Elevated levels of conjugated bilirubin refect obstruction of bile fow in the liver or signifcant liver cell injury. Liver cell function can be investigated by testing how quickly the blood clots. A Doppler ultrasound may reveal the accumulation of fat or scar tissue, impaired blood fow, and obstruction of bile fow in the liver. Patients with elevated liver enzyme levels should have a full evaluation of their liver by a hepatologist or pediatric hepatologist. Patients should be immunized against varicella zoster virus (unless live virus vaccines are contraindicated), hepatitis A virus, and hepatitis B virus. The levels of antibodies against these viruses should be measured to insure that the patient has acquired immunity. Drugs that are toxic to the liver, including alcohol, should be avoided when possible. Levels of fat-soluble vitamins should be monitored on a yearly basis in patients with most forms of liver disease, particularly in cases where bile fow is reduced, known as cholestatic disease. In addition, diarrhea should be evaluated to detect opportunistic organisms, optimal nutritional status should be achieved, and the liver cell injury and/or function should be evaluated (see above) prior to the transplant. Pancreatic insuffciency—a lack of digestive enzymes made by the pancreas that results in impaired food digestion—is uncommon, but should be considered in patients with poor absorption of fat. Cholestasis may lead to poor absorption of the fat-soluble vitamins A, E, D, and K; therefore, levels of these vitamins should be monitored to determine whether vitamin supplementation is needed. Physicians participating in the long-term management of these patients must be aware of this risk. Good to Know Transferrin is a protein in the body that binds and transports iron in the blood. Transferrin saturation refers to the amount of iron carried by the transferrin protein in the blood. The unsaturated iron binding capacity test reveals the amount of transferrin that is not being used to transport iron. A single transfusion unit of packed red blood cells contains 200-250 mg of elemental iron. The body is unable to excrete excess iron; thus, all iron obtained via transfusions must be deposited somewhere in the body. The organs most commonly affected by iron overload include the liver, pancreas, and heart. Patients with iron overload are generally asymptomatic; fatigue is the only commonly reported symptom. Patients often have an enlarged liver, which may be discovered by physical exam, and elevated blood levels of the liver enzyme aminotransferase. Cirrhosis is a rare but irreversible complication of iron overload; therefore, it is important to prevent liver fbrosis, the scarring process 92 Chapter 4: Gastrointestinal, Hepatic, and Nutritional Problems that occurs in response to liver injury that can lead to cirrhosis. Fibrosis may occur earlier than usual in patients with viral hepatitis (particularly hepatitis C), non-alcoholic fatty liver disease, and/or alcohol abuse. Diabetes, joint pain, and heart disease are common in patients with severe iron overload and liver disease. Heart disease may include cardiomyopathy (weakening and enlargement of the heart muscle), irregular heartbeats, or heart failure. Patients receiving blood transfusions should be screened yearly for iron overload. Screening is performed using blood tests to measure transferrin saturation, ferritin, and unsaturated iron binding capacity. A transferrin saturation measurement of greater than 45% or a transferrin saturation measurement of less than 45% with elevated levels of ferritin should prompt further testing and investigation into the patient’s medical history. Patients with highly elevated blood levels of amino acids, obesity, or those suspected of chronic alcohol consumption may need a liver biopsy to detect liver disease or to determine the extent of liver injury due to other causes. Patients who develop iron overload at an early stage in their blood transfusion history or who have a family history of primary iron overload should undergo genetic testing for hemochromatosis, an inherited disorder that causes the body to absorb too much iron. Free radicals are naturally produced in the body as our cells use energy, and may be produced in response to environmental factors such as pollution. Patients with iron overload should avoid vitamins or medications containing iron and vitamin C, but do not need to restrict their consumption of foods 93 Fanconi Anemia: Guidelines for Diagnosis and Management containing iron and vitamin C. Oral chelation should be chosen and monitored in consultation with a physician with some experience with these agents. Nutrition as Therapy Complementary and alternative therapies include any treatments and practices that have not been shown to be effective by evidence-based clinical studies. Complimentary therapies are used in conjunction with standard medical care, and alternative therapies are used in place of standard medical care. Many families view food, and by extension, dietary supplements, vitamins, and micronutrients, as “natural” and thus safe. The multi-billion dollar industry that produces complementary/alternative nutritional regimes lacks federal regulation and has a clear incentive to promote its products regardless of the degree of evidence of the effectiveness of these products. Many complementary/alternative nutritional regimes and supplements are directly harmful or, by displacing standard medical therapy, indirectly harmful. Controlled clinical trials of 94 Chapter 4: Gastrointestinal, Hepatic, and Nutritional Problems supplements are necessary to demonstrate effectiveness and limit the risk of toxicity. Products containing iron must be avoided to reduce the risk of exacerbating iron accumulation in the liver and other tissues. Vitamin C increases iron absorption; therefore, products containing vitamin C, such as multivitamins or fortifed fruit juices/drinks should be avoided. In large studies, both vitamin A and vitamin E supplements have been associated with an increased risk of some cancers; therefore, they should be avoided until further study indicates otherwise. Large doses of omega-3 fatty acids, commonly found in fsh oil supplements, can increase the risk of bleeding due to inactivation of platelets, blood cells that mediate blood clotting. Patients and their families often have the desire to control some aspect of the patient’s care; in this respect, diet seems a harmless choice. Establishing a non-judgmental, but candidly informative discussion of complementary and alternative therapies offers the physician a chance to educate parents about their choices. Physicians and families can access information about complementary/alternative nutritional therapies at the website of the Offce of Complementary and Alternative Medicine of the National Institutes of Health, available at.

A surgical procedure that creates a functional thumb by moving the index fnger and its nerves, arteries, tendons, and muscles to the thumb position. A so-called “foating” thumb that lacks bones and is composed of skin and soft tissue. Children with these anomalies might have a shortened or absent thumb, radius, or both, due to incomplete growth. Therapy or surgery may be required to maximize the function and appearance of the patient’s hands and arms. There are no standardized treatment procedures for congenital hand and arm abnormalities; treatments must be tailored to each child and family. The decision process is multi-factorial and requires participation from the family, physician team, and a physical or occupational therapist. Initial Evaluation Children born with limb abnormalities should be referred to an upper extremity specialist within the frst few months of life. This physician should be comfortable with and profcient in the diagnosis and management of congenital limb anomalies. The initial exam will lay the foundation for the relationship between the doctor, patient, and the patient’s family. It will also provide parents with an opportunity to ask questions about the potential causes, treatments, and outcomes of their child’s limb abnormalities. It is important for physicians to encourage this type of conversation; otherwise, parents often seek health information via the Internet, which can be a source of misinformation. A physical therapist can help to stretch and strengthen the affected limb, and provide adaptive devices that maximize the patient’s independence. As children get older and begin to perform increasingly complex physical activities, many parents will worry that their child’s impairment is worsening, but in reality their child’s activities may simply require additional strength and dexterity.
