Managing Nutrition during Cancer and Treatment

Changes include healthy eating, being physically active, aiming for a healthy weight , and getting healthy amounts of sleep. There are no specific symptoms of overweight and obesity.

The signs of overweight and obesity include a high body mass index BMI and an unhealthy body fat distribution that can be estimated by measuring your waist circumference.

Obesity can cause complications in many parts of your body. Another sign of overweight and obesity is having an unhealthy body fat distribution. Fatty tissue is found in different parts of your body and has many functions. An increased waist circumference is a sign of obesity and can increase your risk for obesity-related complications. Did you know inflammation is thought to play a role in the onset of certain obesity-related complications?

Researchers now know more about visceral fat, which is deep in the abdomen of overweight and obese patients.

Visceral fat releases factors that promote inflammation. More research is needed to understand what triggers inflammation in some obese patients and to find new treatments. Your doctor may diagnose overweight and obesity based on your medical history, physical exams that confirm you have a high body mass index BMI and possibly a high waist circumference, and tests to rule out other medical conditions.

To diagnose overweight and obesity, doctors measure BMI using calculations that depend on whether you are a child or an adult. During your physical exam, your doctor will measure your weight and height to calculate your BMI. If you are of South Asian or Central and South American descent, your doctor may use smaller waist circumference values to diagnose your obesity.

Treatment for overweight and obesity depends on the cause and severity of your condition. Possible treatments include healthy lifestyle changes, behavioral weight-loss treatment programs, medicines, and possibly surgery.

You may need treatments for any complications that you have. To help you aim for and maintain a healthy weight, your doctor may recommend that you adopt lifelong healthy lifestyle changes. Making lifelong healthy lifestyle changes, such as heart-healthy eating and physical activity, can help you modify your energy balance to help you aim for and maintain a healthy weight. Your doctor may recommend you enroll in individual or group behavioral weight-loss programs to treat your overweight and obesity.

In these programs, a trained healthcare professional will customize a weight-loss plan for you. This plan will include a moderately-reduced calorie diet, physical activity goals, and behavioral strategies to help you make and maintain these lifestyle changes.

Researchers know that our brains can become patterned so that we feel pleasure or reward from eating. This can make us unconsciously crave food so our bodies feel that sense of pleasure. It can also make it hard to change our eating patterns, lose weight, or maintain a healthy weight. Researchers are studying whether cognitive behavioral therapies can be an effective treatment for overweight and obesity by retraining the brain to not associate pleasure with food and the act of eating.

When healthy lifestyle changes are not enough, your doctor may treat your overweight and obesity with FDA-approved medicines. These medicines work in the following parts of your body. Weight loss medicines are not recommended as a single treatment for weight loss. These medicines can help you lose weight but when combined with lifestyle changes may result in greater weight loss.

Some of these medicines should not be used if you have certain conditions or are taking certain medicines. Also, these medicines have side effects. Talk to your doctor if you are pregnant, planning to get pregnant, breast feeding, or have a family history of cardiovascular diseases such as high blood pressure, heart attack, or stroke.

Some patients with obesity do not respond to healthy lifestyle changes and medicines. When these patients develop certain obesity-related complications, they may be eligible for the following surgeries.

Talk to your doctor to learn more about the benefits and risks of each type of surgery. Possible complications include bleeding, infection, internal rupture of sutures, or even death.

Read gastric bypass surgery for more information. First, these surgeries reduce the amount of food stored in the stomach and the amount of calories your body can take in. This can help your body restore energy balance. Second, these surgeries change the levels of certain hormones and the way the brain responds to these hormones to control hunger urges. After surgery, some people are less interested in eating or they prefer to eat healthier foods.

If you have been diagnosed with overweight and obesity, it is important that you continue your treatment. Read about tips to help you aim for a healthy weight, the benefit of finding and continuing a behavioral weight-loss program, and ways your doctor may monitor if your condition is stable, worsening, or improving and assess your risk for complications.

Changing lifestyle habits takes time and patience. Follow these tips to help you maintain the healthy lifestyle changes your doctor recommended to aim for a healthy weight.

Some people find it is easier to aim and maintain a healthy weight when they have support from a weight-loss specialist or other individuals who also are trying to lose weight. Behavioral weight-loss programs can provide this support, and they can help you set goals that are specific to your needs. Your weight-loss specialist usually reviews or modifies your goals every six months based on your progress and overall health.

When you are choosing a behavioral weight-loss program, you may want to consider whether the program should:. Your doctor may do any of the following to monitor your condition.

After reading our overweight and obesity Health Topic, you may be interested in additional information found in the following resources. Also known as Adiposity. Overweight and obesity are increasingly common conditions in the United States.

They are caused by the increase in the size and the amount of fat cells in the body. Doctors measure body mass index BMI and waist circumference to screen and diagnose overweight and obesity. Obesity is a serious medical condition that can cause complications such as metabolic syndrome, high blood pressure, atherosclerosis, heart disease, diabetes, high blood cholesterol, cancers and sleep disorders.

Treatment depends on the cause and severity of your condition and whether you have complications. Treatments include lifestyle changes, such as heart-healthy eating and increased physical activity, and Food and Drug Administration FDA -approved weight-loss medicines. For some people, surgery may be a treatment option.

Explore this Health Topic to learn more about overweight and obesity, our role in research and clinical trials to improve health, and where to find more information. Energy imbalances cause the body to store fat. Your body uses certain nutrients such as carbohydrates or sugars, proteins, and fats from the foods you eat to: Sugars are stored as glycogen in the liver and muscles.

White fat tissue can be found around the kidneys and under the skin in the buttocks, thighs, and abdomen. Brown fat tissue is located in the upper back area of human infants. This fat type releases stored energy as heat energy when a baby is cold. It also can make inflammatory substances. Brown fat can be seen in children and adults. Beige fat tissue is seen in the neck, shoulders, back, chest and abdomen of adults and resembles brown fat tissue.

This fat type, which uses carbohydrates and fats to produce heat, increases when children and adults are exposed to cold. Some genetic syndromes and endocrine disorders can cause overweight or obesity. Genetic syndromes Several genetic syndromes are associated with overweight and obesity, including the following. Prader-Willi syndrome Bardet-Biedl syndrome Alström syndrome Cohen syndrome The study of these genetic syndromes has helped researchers understand obesity. People with this condition have low levels of thyroid hormones.

People with hypothyroidism also produce less body heat, have a lower body temperature, and do not efficiently use stored fat for energy. People with this condition have high levels of glucocorticoids , such as cortisol , in the blood. High cortisol levels make the body feel like it is under chronic stress.

As a result, people have an increase in appetite and the body will store more fat. Some tumors, such as craneopharingioma, can cause severe obesity because the tumors develop near parts of the brain that control hunger. Lack of physical activity Lack of physical activity due to high amounts of TV, computer, videogame or other screen usage has been associated with a high body mass index.

Unhealthy eating behaviors Some unhealthy eating behaviors can increase your risk for overweight and obesity. Eating more calories than you use. The amount of calories you need will vary based on your sex, age, and physical activity level.

Find out your daily calorie needs or goals with the Body Weight Planner. Eating too much saturated and trans fats Eating foods high in added sugars Visit Heart-healthy eating for more information about healthy eating patterns. Not enough sleep Many studies have seen a high BMI in people who do not get enough sleep. Many environmental factors can increase your risk for overweight and obesity: Thus, clinicians can use the ratings to differentiate between recommendations based on data from clinical trials and those based on the opinions of experts familiar with the relevant clinical practice and scientific rationale for such practice when clinical trial data are not available.

The antituberculosis medications used in these regimens have varying doses, toxicities, and monitoring requirements Table 8. All patients being given twice-weekly treatment should receive DOT, because nonadherence to intermittent dosing results in a larger proportion of the total doses missed than does daily dosing. DOT should be used whenever feasible, especially with 2-mo regimens and in certain settings e. Isoniazid for 9 mo. The isoniazid daily regimen for 9 mo receives an A recommendation.

Prospective, randomized trials of up to 12 mo of therapy in HIV-uninfected persons suggest that the maximal beneficial effect of isoniazid is achieved by 9 mo; minimal additional benefit is gained by extending treatment to 12 mo.

Thus, this updated recommendation represents a shortening of the previous recommendation of isoniazid daily for 12 mo for HIV-infected persons and a lengthening of the previously recommended 6 mo for HIV-uninfected persons 1. Both mo and 6-mo regimens of isoniazid have substantially reduced rates of TB in HIV-infected persons compared with placebo 88 , but the 6-mo regimen has not been directly compared with the mo regimen in HIV-infected persons.

Thus, the recommendation for 9 mo of isoniazid in HIV-infected persons is based on extrapolation of available data. Intermittent dosing of 9 mo of isoniazid for treatment of LTBI has not been studied comparatively. However, analogous with the continuation phase of treatment for active TB where twice-weekly dosing is equivalent to daily dosing , twice-weekly dosing of isoniazid is also acceptable for treatment of LTBI, but is recommended at the B level as an acceptable alternative regimen.

Isoniazid for 6 mo. Although a 9-mo regimen of isoniazid is the preferred treatment of LTBI for an individual patient, a 6-mo regimen also provides substantial protection and has been demonstrated to be superior to placebo in both HIV-infected and HIV-uninfected persons 32, From a societal perspective, treatment for 6 mo rather than 9 mo may provide a more cost-effective outcome Thus, based on individual situations, health departments or other providers may prefer to concentrate efforts in ensuring the implementation of a 6-mo rather than a 9-mo course of isoniazid.

Isoniazid for 6 mo, taken either daily or twice weekly, is recommended at the B level for HIV-negative persons and at the C level for HIV-positive persons.

The shorter regimen is not recommended for children or persons with radiographic evidence of prior tuberculosis. Rifampin and pyrazinamide for 2 mo. The 2-mo daily regimen of rifampin and pyrazinamide is recommended on the basis of a prospective randomized trial of treatment of LTBI in HIV-infected persons that demonstrated the 2-mo regimen to be similar in safety and efficacy to a mo regimen of isoniazid Although this regimen has not been evaluated in HIV-uninfected persons with LTBI, the efficacy is not expected to differ significantly.

However, the toxicities may be increased ; therefore, the recommendation is made at the A level for HIV-infected persons and at the B level for HIV-uninfected persons until further data are available. Two randomized, prospective trials of intermittent dosing of rifampin and pyrazinamide for 2 and 3 mo, respectively, have been reported in HIV-infected persons 86, ; in neither case was the sample size adequate to conclude with certainty that efficacy was equivalent to daily dosing.

Moreover, both studies compared the twice-weekly rifampin and pyrazinamide regimen to the 6-mo isoniazid regimen. Therefore, rifampin and pyrazinamide given twice weekly for mo may be considered when alternative regimens cannot be given.

This recommendation is made at the C level. Rifampin for 4 mo. Rifampin given daily for 3 mo has resulted in better protection than placebo in treatment of LTBI in HIV-uninfected persons with silicosis in a randomized prospective trial This option may be useful for patients who cannot tolerate isoniazid or pyrazinamide.

Because more than one regimen can be used to treat LTBI, health care providers should discuss options with the patient, and, when possible, help patients make the decision, unless medical indications dictate a specific regimen. Discussion should include the length and complexity of the regimens, possible adverse effects, and potential drug interactions.

Completion of therapy is based on total number of doses administerednot on duration of therapy alone. The 9-mo regimen of daily isoniazid should consist of doses, at minimum, administered within 12 mo, allowing for minor interruptions in therapy. The 6-mo regimen of isoniazid should consist of at least doses administered within 9 mo. Twice-weekly isoniazid regimens should consist of at least 76 doses administered within 12 mo for the 9-mo regimen and 52 doses within 9 mo for the 6-mo regimen.

The daily regimen of rifampin or rifabutin and pyrazinamide should consist of at least 60 doses to be administered within 3 mo. The regimen of daily rifampin alone should consist of at least doses administered within 6 mo. Ideally, patients should receive medication on a regular dosing schedule until completion of the indicated course.

However, in practice some doses may be missed, requiring the course to be lengthened. When reinstituting therapy for patients who have interrupted treatment, clinicians might need to continue the regimen originally prescribed as long as needed to complete the recommended duration of the particular regimen or renew the entire regimen if interruptions were frequent or prolonged enough to preclude completion of treatment as recommended.

In either situation, when therapy is restored after an interruption of more than 2 mo, a medical examination to rule out active TB disease is indicated.

Treatment of HIV-infected persons. Recommendations for HIV-infected adults largely parallel those for HIV-uninfected adults, although the quality of evidence and strengths of the recommendations vary Table In addition, rifampin is generally contraindicated or should be used with caution in persons who are taking protease inhibitors PIs or NNRTIs Experts have recommended that for HIV-infected persons who are candidates for treatment of LTBI and need PI or NNRTI therapy, rifabutin can be substituted for rifampin in some circumstances; rifabutin can safely be used with indinavir, nelfinavir, amprenavir, ritonavir, and efavirenz, but not with hard-gel saquinavir, or delavirdine.

Caution is advised if rifabutin is administered with soft-gel saquinavir, because data regarding use of rifabutin with soft-gel saquinavir or nevirapine are limited. No specific data have been generated for treatment of LTBI with rifabutin-containing regimens, but such a recommendation is supported by analogy with treatment for active TB where rifabutin can be substituted for rifampin with no loss of efficacy and by experimental studies in mice , Rifabutin can be administered at one half the usual daily dose i.

The daily rifabutin dose is mg or mg when used with efavirenz; pharmacokinetic studies suggest that rifabutin might be given at usual doses with nevirapine. For patients receiving multiple PIs or a PI in combination with an NNRTI, drug interactions with rifabutin are likely more complex; in such situations, the use of rifabutin is not recommended until additional data are available. The substitution of rifapentine for rifampin is not recommended because rifapentine's safety and effectiveness have not been established for patients infected with HIV Furthermore, the drug interactions between rifapentine and HIV protease inhibitors have not been studied in detail, although one study has indicated that rifapentine causes substantial reduction in the serum level of indinavir when the drugs are given together Furthermore, some experts recommend treatment of possible LTBI for HIV-infected residents of institutions that pose an ongoing high risk for exposure to M.

These regimens include 9 mo of isoniazid, 2 mo of rifampin plus pyrazinamide, or 4 mo of rifampin with or without isoniazid , providing that infection with drug-resistant organisms is judged to be unlikely. Patients who begin multidrug therapy for suspected pulmonary TB but are subsequently determined not to have active disease i. Persons with evidence suggestive of healed, primary TB i. Their risk for TB and need for treatment of LTBI should be determined by consideration of other risk factors and the size of the tuberculin reaction Table 7.

Although one study demonstrated a decrease in lymphocyte reactivity to tuberculin during pregnancy , other studies have not demonstrated an effect of pregnancy on cutaneous delayed hypersensitivity to tuberculin , The current classification scheme for interpreting the Mantoux tuberculin skin test is likely valid in pregnancy, although it has not been verified in this group of women.

There is no evidence that the tuberculin skin test has adverse effects on the pregnant mother or fetus Although the need for treatment of active TB during pregnancy is unquestioned, the treatment of LTBI in pregnant women is more controversial. Some experts prefer to delay treatment until after delivery because pregnancy itself does not increase the risk of progression to disease, and two studies suggest that women in pregnancy and the early postpartum period may be vulnerable to isoniazid hepatotoxicity 91, However, because conditions that promote hematogenous spread of organisms to the placenta e.

The possible risk for isoniazid hepatotoxicity must be weighed against the risk for developing active TB and the consequences to both the mother and her child should active disease develop. Extensive use of isoniazid during pregnancy has indicated that although it readily crosses the placental barrier, the drug is not teratogenic even when given during the first 4 mo of gestation Hemorrhagic disease of the newborn has been described following the use of rifampin in the mother However, extensive experience with the use of rifampin to treat TB in pregnant women suggests it is safe in most circumstances.

Although pyrazinamide has been used to treat TB in pregnant women, no published data exist concerning the effects of the drug on the fetus. Thus, although pyrazinamide may be considered after the first trimester in women with HIV infection , it should otherwise be avoided. The preferred regimen for treatment of LTBI in pregnant women is isoniazid, administered either daily or twice weekly. Although rifampin is probably safe, no efficacy data support its use.

For women at high risk for progression of LTBI to disease, especially those who are infected with HIV or who have been infected recently, initiation of therapy should not be delayed on the basis of pregnancy alone, even during the first trimester. Pregnant women taking isoniazid should receive pyridoxine supplementation.

Toxic effects of antituberculosis drugs delivered in breast milk have not been reported. Breastfeeding is not contraindicated when the mother is being treated for LTBI. However, infants whose breastfeeding mothers are taking isoniazid should receive supplemental pyridoxine. The amount of isoniazid provided by breast milk is inadequate for treatment of the infant. Several fundamental aspects of the natural history and treatment of LTBI in children must be considered when making recommendations about therapy.

Infants and young children i. The risk for progression decreases gradually through childhood. Infants and young children are more likely than older children and adults to develop life-threatening forms of TB, especially meningeal and disseminated disease.

The risk for isoniazid-related hepatitis is minimal in infants, children, and adolescents, who generally tolerate the drug better than adults , Isoniazid therapy is widely accepted for use in children. Because of differences in pathogenesis of TB infection and disease in children compared with adults, information from clinical trials involving adults cannot be applied directly to children without confirmatory pediatric trials.

The only published efficacy trials of treatment of LTBI in children have studied isoniazid alone. Routine monitoring of serum liver enzyme concentrations is not necessary but should be considered in children at risk for hepatic disease. When children taking antituberculosis therapy develop hepatitis, a search for causes other than isoniazid or other drugs should be undertaken and the therapy discontinued.

Routine administration of pyridoxine is not recommended for children taking isoniazid, but should be given to 1 breastfeeding infants, 2 children and adolescents with diets likely to be deficient in pyridoxine, and 3 children who experience paresthesias while taking isoniazid. Isoniazid given twice weekly has been used extensively to treat LTBI in children, especially schoolchildren and close contacts of case patients On the basis of clinical experience, this method of administration is safe, but its effectiveness has not been established definitively.

DOT should be considered when it is unlikely that the child and family will be adherent to daily self-administration. In the United States, rifampin alone has been used for the treatment of LTBI in infants, children, and adolescents when isoniazid could not be tolerated or the child has had contact with a case patient infected with an isoniazid-resistant but rifamycin-susceptible organism However, no controlled clinical trials have been conducted.

A 3-mo regimen of rifampin and isoniazid has been used in England, with programmatic data suggesting that the regimen is effective No reports have been published concerning the efficacy of rifampin and pyrazinamide therapy in children with LTBI, although a randomized study involving a limited number of children indicated that this regimen was well tolerated The American Academy of Pediatrics currently recommends a 9-mo course of isoniazid Most experts recommend that routine monitoring of serum liver enzyme concentrations be performed and pyridoxine given when HIV-infected children are treated with isoniazid.

The optimal length of rifampin therapy in children with LTBI is not known; however, the American Academy of Pediatrics recommends 6 mo of treatment Similarly, of high school students who took rifampin after being exposed to a patient with isoniazid-resistant, active TB, none developed TB during the second year of the study However, one episode of rifampin prophylaxis failure was reported among contacts of a case patient with isoniazid-resistant TB in a community outbreak For contacts of patients with isoniazid-resistant, rifampin-susceptible TB, a 2-mo regimen of rifampin and pyrazinamide is recommended.

For patients with intolerance to pyrazinamide, a 4-mo regimen of rifampin alone is recommended. In situations in which rifampin cannot be used, rifabutin can be substituted. Persons infected with isoniazid- and rifampin-resistant organisms are unlikely to benefit from treatment with regimens containing these agents. Therefore, use of a regimen containing other agents active against M. When possible, selection of drugs for such a regimen should be guided by in vitro susceptibility test results from the isolate to which the patient was exposed and is presumed infected.

For persons who are likely to be infected with MDR TB and at high risk of developing TB, pyrazinamide and ethambutol or pyrazinamide and a fluoroquinolone i. Immunocompetent contacts may be observed without treatment or treated for at least 6 mo; immunocompromised contacts e. Side effects of pyrazinamide and fluoroquinolones include gastrointestinal symptoms and hepatic transaminase elevations All persons with suspected MDR TB infection should be followed for at least 2 yr, irrespective of treatment.

The combination of pyrazinamide and ethambutol for mo is recommended if the isolate is susceptible to both drugs. Long-term use of fluoroquinolones in children should be avoided. Deleterious effects on growing cartilage have been observed in animals treated with fluoroquinolones , although no defects in bone growth occurred among a limited number of children with cystic fibrosis treated with ciprofloxacin or ofloxacin When pyrazinamide and ethambutol cannot be used, many experts recommend using a combination of two other drugs to which the infecting organism is likely susceptible , Low-risk tuberculin test reactors.

When treatment of LTBI is being considered for persons who are at low risk for developing TB, the decision should be based on factors such as likelihood of drug toxicity if treatment is given and likelihood of TB transmission to vulnerable contacts e.

Included in this decision are the patient's preferences and values. When the assessed risk of drug toxicity exceeds the anticipated benefits of therapy, treatment for LTBI is not usually appropriate. The criteria previously described should be applied without modification Directly observed therapy and measures to increase adherence.

Any regimen that is given intermittently i. Some experts recommend that the 2-mo regimen of daily rifampin and pyrazinamide also be given by DOT, which, for ease of administration, may consist of five observed and two self-administered doses each week. Patients with the highest priority for DOT are those at the highest risk of progression from latent to active TB, including persons with HIV infection and young children who are contacts of infectious patients with pulmonary TB.

DOT may be conveniently and effectively used for the treatment of household contacts of patients receiving DOT for active TB and for treatment observed by staff members in certain facilities e. If it is not possible to provide DOT to enhance adherence with treatment of LTBI, the prescribed regimen should be incorporated into patients' daily routines.

Medical providers can encourage adherence to treatment by establishing rapport with patients. Providers should explain in simple, clear language what LTBI is, the health threat it presents, and how it is eradicated. Patients should be encouraged to ask questions. Patient education should ideally be conducted in the patient's primary language, or through a medical interpreter, if necessary.

Each visit between patient and medical provider during therapy is an opportunity to reinforce the patient's understanding of LTBI and its treatment. In addition to education about potential drug toxicity, patients should be told about common side effects and counseled on drug management. For example, medications should be taken with food when gastrointestinal symptoms have occurred after medication was taken on an empty stomach, and salicylic acid can be used for symptomatic treatment of arthralgia caused by pyrazinamide.

Most interventions to improve adherence require substantial financial resources. Providing flexible clinic hours, reducing waiting times for patients, spending time with patients to counsel and educate, and directly observing patients ingesting medications increase operating expenses. Even the least intensive approaches to improve adherence increase program costs. The costs of these approaches to improving patient adherence underscore the need to target tuberculin testing and treatment of LTBI to those groups with an increased risk for recent infection or those persons at high risk for progression to active TB, if infected.

In addition, programs should invest in approaches to increase adherence, especially for those persons who are at greatest risk for progressing to disease. Better success in motivating patients to accept and to complete treatment is necessary to achieve the full potential of this intervention to protect persons from TB and to reduce the incidence of the disease in the community.

The pretreatment evaluation of persons who are targeted for treatment of LTBI provides an opportunity for health care providers to a establish rapport with patients, b discuss the details of the patients' risk for TB, c emphasize the benefits of treatment and the importance of adherence to the drug regimen, d review possible adverse effects of the regimen, including interactions with other drugs, and e establish an optimal follow-up plan.

The evaluation should include an interview conducted in the patients' primary language with assistance of qualified medical interpreters, if necessary. The patient history should document risk factors for TB, prior treatment for TB or LTBI, and preexisting medical conditions that constitute a contraindication to treatment or are associated with an increased risk for adverse effects of treatment. A detailed history of current and previous drug therapy should be obtained, with particular attention to previous adverse reactions to drugs contemplated for treatment of LTBI, and to current use of drugs which may interact with the drugs used for treatment.

Women receiving rifampin and oral contraceptives are at increased risk for becoming pregnant and should be advised to consider an additional form of contraception. Practitioners should consider using a standardized history form to ensure that all elements of the pretest evaluation are thoroughly covered for each patient.

Baseline laboratory testing is not routinely indicated for all patients at the start of treatment for LTBI Table 8. Baseline testing is also indicated for patients infected with HIV, pregnant women and those in the immediate postpartum period i.

Baseline testing is no longer routinely indicated in persons older than 35 yr of age. Clinical monitoring is indicated for all patients; this involves education of patients about the symptoms and signs that can result as adverse effects of the drug s being prescribed and the need for prompt cessation of treatment and clinical evaluation should symptoms occur. These include any of the following: Clinical monitoring begins at the first visit and should be repeated at each monthly visit.

At monthly visits, patients should be instructed to interrupt therapy and contact their providers immediately upon the onset of such symptoms or any unexplained illness occurring during treatment. Patients being treated for LTBI should receive a clinical evaluation, including a brief physical assessment checking for signs of hepatitis, at least monthly if receiving isoniazid alone or rifampin alone and at 2, 4, and 8 wk if receiving both rifampin and pyrazinamide Table 8.

These evaluations represent opportunities to review the indications for treatment, adherence with therapy since the last visit, symptoms of adverse drug effects and drug interactions, and plans to continue treatment. As with the baseline evaluation, a standardized questionnaire may facilitate those interviews.

Routine laboratory monitoring during treatment of LTBI is indicated for patients whose baseline liver function tests are abnormal and for other persons at risk for hepatic disease Table 8. In addition, laboratory testing e. Some experts recommend that isoniazid be withheld if a patient's transaminase level exceeds 3 times the upper limit of normal if associated with symptoms and five times the upper limit of normal if the patient is asymptomatic.

Reporting of serious adverse events. Practitioners and other health professionals should report serious adverse events associated with the treatment of LTBI to the U. Food and Drug Administration's MedWatch program. Serious adverse events include those associated with hospitalization, permanent disability, or death.

However, the specificity of the test is decreased by cross reactions from BCG vaccination and sensitization by nontuberculous mycobacteria. When used in populations in which the risk for TB is low, the test's positive predictive value is poor. In addition, the requirement that the person tested return for the test to be read h after test administration creates operational problems.

Thus, more specific and sensitive tests are needed to diagnose LTBI and to identify persons at greatest risk for progressing to active disease. Especially useful would be tests that distinguish skin-test reactions caused by TB infection from those caused by BCG vaccination or infection with nontuberculous mycobacteria, tests that correlate with the presence of living organisms, and tests that accurately identify LTBI in immunodeficient persons.

More data are needed regarding the acceptability, tolerability, and effectiveness of the 2-mo regimen of daily rifampin and pyrazinamide in HIV-negative persons.

Data are especially needed from older adults and children. No studies of rifampin alone taken twice weekly for the treatment of LTBI have been conducted. Data from two studies in HIV-infected persons that included intermittent i. Before additional trials of intermittent rifampin regimens are undertaken, animal model data are needed to compare these regimens with regimens using other longer-acting rifamycin derivatives see Efficacy Studies of New Drugs.

It is unlikely that a formal efficacy study of intermittent isoniazid for the treatment of LTBI will be undertaken, unless it is included as a control arm for studies of newer regimens.

However, several TB-control programs have had considerable experience using this regimen. Data from these programs should be examined, especially as they relate to acceptability and completion of treatment. The analysis of aggregate data available in TB programs may also be useful in estimating the effectiveness of this regimen.

Studies are needed to provide information regarding the use of newer regimens for the treatment of LTBI in children and pregnant women. The safety of pyrazinamide for pregnant women and their fetuses should be determined. More information is needed regarding hepatotoxicity of isoniazid in pregnant and postpartum women.

Studies are needed to establish the safety and effectiveness of rifampin alone and rifampin plus pyrazinamide for treatment of LTBI in infants, children, and adolescents. The best target populations for these studies would be HIV-infected children in places in which TB is prevalent and household contacts of TB case patients. In addition, the effectiveness of twice-weekly regimens for treatment of LTBI in children should be confirmed. Finally, epidemiologic research to determine the best tools to identify children at high risk for LTBI should be undertaken.

These recommendations call for the establishment of LTBI treatment programs in new community settings e. Consequently, operational research will be needed to evaluate the implementation of these programs in settings other than health departments. These studies should assess the knowledge base of treating clinicians and identify the obstacles to be overcome for the successful implementation of community-based LTBI treatment programs.

If field and programmatic data establish the effectiveness and acceptability of the rifampin and pyrazinamide regimen for the treatment of LTBI, the availability of a combination product would facilitate its administration. However, the argument concerning the usefulness of combination products in preventing the emergence of drug resistance in patients with active TB is not as compelling for persons being treated for LTBI.

Nonetheless, methods to facilitate provision of this treatment and increase adherence e. However, several rifamycin derivatives with half-lives substantially greater than rifampin are of interest because of the possibility of widely spaced, intermittent administration.

In experimental studies involving mice, the combination of rifapentine and isoniazid given once weekly for 3 mo was as active as rifampin and pyrazinamide given daily for 2 mo Rifalazil, which has an even longer half-life, is more active than rifapentine and perhaps could be dosed less frequently without compromising efficacy The class of nitroimidazole compounds is also of interest because of their potential activity against dormant tubercle bacilli Unfortunately, no animal models of LTBI exist that optimize the preclinical evaluation of new drugs.

Studies of Immunomodulators and Vaccines Recent studies have indicated that immunotherapy with specific cytokines and immunomodulators may be beneficial to response to TB treatment. However, their application in the treatment of LTBI is uncertain. Some epidemiologic studies have suggested that high levels of certain cytokines e. If further studies support this finding, interventions that stimulate production of protective cytokines may have a role in the treatment of LTBI.

The development of a postinfection vaccine to be administered to persons with LTBI has been given high priority Future decision and cost-effectiveness analyses should be expanded to include targeted testing. Instead of beginning at the "treat-don't-treat" point, new models might be most useful if they begin with the decision of whether to test.

These studies should focus on groups at high risk and specific subgroups characterized by varied risks and benefits of treatment. Using this conceptual framework will help place decision modeling more clearly into a "real world" context, incorporating the linked contingencies that exist. Future decision and cost-effectiveness analyses should compare the shorter course regimens to the longer, 9-mo regimen of daily isoniazid.

These analyses will benefit from investigations of the toxicities and efficacies of shorter regimens. In addition, although adherence presumably will be better with shorter treatment regimens, the rifampin and pyrazinamide regimen may be less well-tolerated in some groups of patients, thus resulting in low adherence. Decision and cost-effectiveness analyses should explore a range of toxicities in the models until investigations better establish these risks.

By investigating the effect of a range of toxicities and adherence on the decision outcome, studies can help identify priority areas for research.

Updated analyses on the use of alternate regimens for the treatment of drug-resistant LTBI are also needed. When two different perspectives are relevant for a decision, both perspectives should be modeled and analyzed. For example, when the benefits to an individual person with LTBI are different from the benefits to the public, both perspectives must be made explicit in decision models. When decision analysis is inadequate to deal with public health issues e.

Policies designed to target and treat populations at high risk for TB are motivated by the need to benefit the individual patient as well as the health of the public by averting active disease in persons most likely to develop it. As policies are instituted that identify high-risk groups for testing and treatment, the social and ethical ramifications of these policies must be considered. The individual persons who comprise many of the high-risk groups targeted for testing and treatment often represent disenfranchised segments of urban populations e.

Ideally, the outcomes and utilities that are used in these decision models will incorporate the values and preferences of these patients and the outcomes important to the general public.

As the parent of a toddler who has an eating problem, we've tried everything and then some to encourage our daughter to eat. I'm guessing that you can't imagine celebrating your child eating 3 blueberries each cut into quaters so that she can swallow them We were lucky because our daughter would still drink almost enough calories to meet her needs, and she had plenty of energy.

So far it has been 7 months of early intervention and numerous sessions Yes, she actually couldn't eat for a number of sensory reasons For some families, it takes a decade or longer and externally given nutrition.

Having a child who can eat well is something to be greatful for. My 2 year old son will not eat very well no matter what. He had bad reflux as a baby and is working with an OT for eating, but that still has not gotten him to eat better.

He will be getting a feeding tube in a few weeks. A feeding tube sounds so scary I'm sorry he and you have to go through that! Best wishes for his speedy recovery.

In regards to not eating check for EE our son has it, only found out because he was refusing to eat had not gained a pound in over year in half. It's very typical for toddlers to be picky eaters or eat what perceive to be very little.

However, at this stage of the development, they are not growing as much as they did the first year and don't need that many calories for their bodies. It's best to offer food that is nutritional and what they like and not force them to eat. I'm sorry, but I disagree with making this a general statement. Parents should discuss this with their Peds because some toddlers are functionally starving.

There is an important difference between a picky toddler It can be really hard to find the line between the two. Kids can most certainly starve themselves! You may not know it, but they may not be eating enough to support their system and that could cause serious organ failure. And if you don't like the answers they give, talk with someone else. You are your child's only advocate. There is some information that would have been nice to have from the parent.

One thing is why is a 3. Does she have a motor impairment that makes it so she can't feed herself or does she just refuse to do it. Is this child developing typically otherwise no cognitive, social, or motor delays. Has she always been this small or has there been a drop in her growth percentile over time.

How much liquids does the child drink is she filling up on milk and juice and thus not eating and not getting her nutrients specifically enough iron.

She definitely needs to see a doctor for the simple fact that the child is acting overly tired and cranky. A referral to an ST or OT may be needed if a feeding disorder is suspected.

I agree with most of the parents here — the child needs to be evaluated to see if motor skills or other development is delayed for some physical reason, and to see if there is some underlying medical condition.

My nephew started losing weight because he turned down his food and they found out his tonsils were so large they were practically clogging his throat. He probably always had a mild sore throat but wasn't a complainer — he just didn't want to eat.

OTH my older son was always at the very bottom of the percentile chart — even off the chart for a little while! He didn't eat a lot, but nobody was worried about him. I kept waiting for him to enter that phase where he eats you out of house and home but he never did that, and he never was sickly or dreadfully underweight, so I didn't make an issue of it.

My other son, however, definitely had a bottomless pit stage Could be a milk allergy. I just discovered my twin girls have one. Now that we are off of milk, they are eating alot more. The milk was causing constipation and so they were not as hungry. I disagree with doctors when they say toddlers are supposed to eat like birds. My girls run all day long so how could they not need food energy.

I think there's a reason if kids aren't eating. And if kids are hungry then they are going to be cranky. I too was from a family where we had no lxiurues and mum always used to put dinner on the table with no choices etc.

I have two children both being boys. My eldest is a very good eater and I always used to use our food for his meals. From an early age he used to eat and enjoy a variety of varied foods and when on holiday in France or Spain used to try and eat everything in the restaurants the same as use from a very early age around 4. My second son is the problem eater. He used to until just before his second birthday eat our meals the next mashed or precessed and then heated up.

It was when he had a bad cold one day is simply refused his dinner. From then on he has never eaten meat or vegetables as a meal. He did for many years only eat peanut butter sandwiches and yogurts. He will now eat pizza and chips, together with crisps and chocolate, but his diet is very limited. He is now 17 and nothing has changed over the last few years.

I still cannot understand to this day why this happened especially as my first son is an extremely good eater. He does though surprise me sometimes and will ask to try something new! My youngest will be 3yrs old tomorrow. She weighs 22lb and has been off the growth chart since she turned a year old.

I let her doctor test her for way too many things unfortunately. All those crazy and sometimes invasive test showed that nothing they know of is wrong with her. I should have went with my gut which was tell me nothing she is perfectly fine. Some people are just meant to be little and she is one of them. If your LO is not even trying to feed herself you should probably get her evaluated.

The not feeding herself and being lethargic would set off alarms for me to take my LO to a doctor. My 1 year old daughter is about 15 lbs born 3 weeks early and was 5 lbs at birth , she is very active and seems very normal. Her pediatrician is concerned about her weight and wanted to do several tests to rule out potential issues. The doctor asked us to give my daughter pediasure once a day for a month and if there is no decent weight gain, she would want to start the tests.

Some of friends say that a child in their 1st year birthday should weigh about 3 times the birth weight, if this is true my daughter should ok given that she is very active as well. Wish me good luck. I guess you could give them candy bars Just keep them at the table and have them visually see the family eating.

And, eventually, they'll eat. Unless there is an actual medical issue, kids will eventually eat. If a kid has the ability to put sweets in their mouth, chew and swallow it, then they have the ability to do the same with nutritious food. Make all options well rounded and nutritious and only have sweets as an occasional reward after eating real food.
