In order to assess the seroprevalence and coprevalence of hepatitis-B surface antigen (HBsAg), human immunodeficiency virus-1 and -2 (HIV-1 and -2) antibodies in Nigerian children with/without protein energy malnutrition (PEM), we studied plasma specimens of 206 children with PEM and 200 apparently healthy reference children aged between 1 and 3 years by enzyme-linked immunosorbent assays (ELISA). HIV-seropositive cases were confirmed by immunoblotting (IB). Of the children studied, eight (4%) of the healthy and four (1.9%) of the malnourished (P = 0.22, Fisher's exact test) were positive for HIV-1 antibodies, 40 (20%) of the healthy and 54 (26%) of the malnourished (P = 0.14) were positive for HBsAg, and five (2.5%) of the healthy and four (1.9%) of the malnourished (P = 0.70) were positive for both HIV-1/HBsAg. No case of HIV-2 antibodies was found. While the seroprevalence of HBsAg was higher in the malnourished subjects, the reverse was the case with HIV antibodies. However, all the four HIV-1-positive malnourished children and five of eight of the HIV-1-positive reference children were simultaneously positive for HBsAg. This is the first epidemiological report on the seroprevalence and coprevalence of HIV and HBsAg in apparently healthy and malnourished Nigerian children.

Only about 15% of the subjects abusing ethanol will eventually develop cirrhosis of the liver, suggesting that other factors in addition to the consumption of large quantities of ethanol play a role in the pathogenesis of alcoholic cirrhosis. Important contributors may be infection with hepatitis viruses, in particular HCV, protein-calorie malnutrition and immunologic factors. Abstinence improves the prognosis of patients with alcoholic cirrhosis, provided that the liver disease is not too far advanced. No pharmacotherapeutic intervention has shown a convincing improvement of the prognosis of alcoholic liver disease, so that the therapeutic efforts should be mainly directed towards abstinence. The patient with alcoholic liver disease needs support and guidance by the treating physicians. Supportive treatment with Disulfiram, Acamprosate or Naltrexon can help with achieving durable abstinence.

Deficiency of 3beta-hydroxy-delta5-C27-steroid dehydrogenase (3beta-HSDH), the enzyme that catalyses the second reaction in the principal pathway for the synthesis of bile acids, has been reported to present with prolonged neonatal jaundice with the biopsy features of neonatal hepatitis. It has also been shown to present between the ages of 4 and 46 months with jaundice, hepatosplenomegaly, and steatorrhoea (a clinical picture resembling progressive familial intrahepatic cholestasis). This paper reports two children with 3beta-HSDH deficiency who developed rickets during infancy and did not develop clinically evident liver disease until the age of 3 years. Bile acid replacement resulted in considerable clinical and biochemical improvement. The importance of thorough investigation of fat soluble vitamin deficiencies in infancy is emphasised.

The present study aimed to describe the clinical manifestations of celiac sprue related to malnutrition and to analyze the associations between celiac sprue and other diagnoses. A case-control study compared the occurrence of comorbid diagnoses in case and control subjects with and without celiac sprue, respectively. All patients with a primary or secondary diagnosis of celiac sprue (ICD-579.0) who were discharged from hospitals of the Department of Veterans Affairs between 1986 and 1995 were selected as case subjects. In a multivariate logistic regression analysis, the occurrence of celiac disease served as outcome variable, while age, gender, ethnicity, and the comorbid occurrences of other diagnoses served as predictor variables. A total of 458 individual patients with celiac sprue were identified. The data confirmed the known associations of celiac sprue with dermatitis herpetiformis, lactase deficiency, enlargement of lymph nodes, and lymphoma. Celiac sprue was also found to be statistically significantly associated with pancreatic insufficiency, Crohn's disease, functional bowel symptoms, chronic nonalcoholic hepatitis, and pulmonary eosinophilia. The nutritional manifestations associated with celiac disease included nutritional marasmus, cachexia, weight loss, hypocalcemia, osteoporosis, vitamin B-complex deficiency, and various types of iron- and vitamin-deficiency anemias. The large variety of complex associations clearly indicates that celiac sprue is a systemic disease that involves multiple organs and exceeds an isolated nutritional intolerance to gluten.

Schistosomiasis is one of the main health problems hindering socio-economic development in Egypt. It affects millions at an early age, diminishing productivity and exerting a significant socio-economic impact. Schistosomiasis endemicity in Egypt varies in different areas. Schistosoma mansoni, with a prevalence generally ranging between 20 to 40%, has replaced Schistosoma haematobium in the Nile Delta, and the latter is now localized to upper Egypt with low endemicity levels (5-10%). The pathology of schistosomiasis consists essentially of a series of chronic inflammatory lesions produced in and around blood vessels by eggs or their products and sometimes by dead adult worms. If the ova continued to be deposited in sufficient numbers and over several years, they would ultimately lead to progressive fibrosis of the portal tracts and urinary bladder, or may be carried in blood and become trapped in the lungs, gastro-intestinal and genital tracts with only occasional association with other organs. The etiology of human pipe-stem fibrosis is still not understood. The host immune response and frequency of exposure and the time of re-infection interval appear to be involved in the overall process of fibrosis. Additional factors are probably involved in the human disease as genetic host susceptibility, malnutrition, repeated infections and repeated treatment, mixed infections including hepatitis, tuberculosis and typhoid. Reversibility of the fibrosis might be related to the proportion of the collagen types present. Immuno-histopathological demonstration of various types of collagen confirms the importance of time for administration of the treatment and period of follow-up. According to previous studies, the timing for treatment affects the reversibility of liver fibrosis emphasizing the importance of early treatment of schistosomiasis to prevent complications.

Thirty-two patients were enrolled in an open-label, dose/schedule ranging clinical trial to evaluate the efficacy and tolerability ofliposomal amphotericin B (Ambisome) in the treatment of visceral leishmaniasis. All patients received a dose of 2mg/kg daily for the first 4 days, followed by a single repeat dose of 2mg/kg at day 10 in 4 patients (total dose 10mg/kg); repeat doses on days 5, 6, and 10 in 13 patients (total dose 14mg/kg); or daily doses were continued on days 5 through 10 in 15 patients (total dose 20mg/kg). Patients had a mean age of 9 years, ranging between 3 and 26 years. Their mean weight was 25.9kg, ranging between 9.5kg and 75kg. All patients had splenomegaly, 31/32 had hepatomegaly, and 20 patients tested had leishmania documented on splenic aspirate. Six of the 32 patients were treated after relapse following antimony therapy. The duration of illness prior to therapy was a mean of 2 months, ranging between 2 weeks and 23 months. During and after treatment, there were significant reductions in liver and spleen sizes, and significant increases in body weight, hemoglobin levels and white blood cell counts. All patients showed initial cure at the 1 month follow-up. Seven patients relapsed between 2 and 6 months after the start of treatment. There was no dose relationship to the occurrence of relapse. The relapse rate in children 5 years of age or less was 7/15 (47%). Associated causes of relapse were refractory disease (i.e., previous relapses) in 2, severe malnutrition in 1, and concurrent disease (meningococcal meningitis) in 1. In the other 2 cases, no associated event was observed except young age (ages 3 and 5 years). One relapsed patient was treated successfully with 14 days of lipid amphotericin B, and the others were cured by use of antimony for 20 to 30 days. There were no dose related adverse events. The most common event was fever which occurred in 13/32 patients (41%); 3/4 patients in the 10mg dose group, 7/13 in the 14mg dose group, and 3/15 in the 20mg dose group. Three patients had cardiac arrhythmia, one also with myocarditis diagnosed 2 weeks after therapy was discontinued. One patient developed hepatitis after dose 3 and the drug was discontinued. We concluded that liposomal amphotericin B is effective in a daily dose of 2mg/kg given for 5-10 doses as an initial cure, but that relapse occurs in young children, particularly those with documented treatment resistant disease or concurrent malnutrition or infection. Patients should be carefully monitored for these risk factors before and during the months alter therapy, and for the occurrence of arrhythmia, cardio-pulmonary effects or hepatotoxicity. This treatment provides an important advance over previously used antimony therapy and appears to be more effective and well-tolerated than non-lipid amphotericin B.

ADDs can occur as primary genetic disorders or may develop secondary to various other conditions, including infections, trauma, malnutrition, and protein-losing states. Although antibiotics are the first-line therapy for acute infection, using them prophylactically can select for resistant organisms. IM ISG and fresh frozen plasma were the principal agents for antibody-replacement therapy until the advent of IVIG 2 decades ago. IVIG is now the definitive product for antibody-replacement therapy. Although IVIG has a long history of safety regarding the infectious pathogens, the identification of more than 100 patients with non-A, non-B hepatitis apparently acquired from a single product prompted additional modifications, improving the safety profile of IVIG. Despite the excellent safety record of IVIG, the unexpected occurrence of hepatitis in some recipients served as a reminder that IVIG is a biologic product derived from human plasma. Newer products are being developed that may supplement polyvalent IVIG including humanized MAbs and hyperimmune IVIG preparations to address specific clinical requirements.

Polycystic liver disease (PLD) may provoke massive hepatomegaly and severe physical and social handicaps. Data on orthotopic liver transplantation (OLT) for PLD are rare and conflicting. Conservative surgery (resection or fenestration) is indicated for large single cysts, but its value for small diffuse cysts is questionable. In addition, conservative surgery is not devoid of morbidity and mortality. OLT offers the prospect of a fully curative treatment, but controversy remains because those patients usually have preserved liver function. Thus, we reviewed our experience with OLT for PLD. Sixteen adult women underwent OLT for small diffuse PLD between 1990 and 1999. Mean age was 45 years (range, 34 to 56 years). Fourteen patients had combined liver and kidney cystic disease, but only 1 patient required combined liver and kidney transplantation, whereas 13 patients underwent OLT alone. Two patients had isolated PLD. Indications for transplantation were massive hepatomegaly causing physical handicaps (n = 16), social handicaps (n = 16), malnutrition (n = 4), and cholestasis and/or portal hypertension (n = 5). OLT caused no technical difficulty in 15 of 16 patients (surgery duration, 6.8 hours; range, 5 to 8 hours), with blood transfusions of 7.9 units (range, 0 to 22 units). One patient who underwent attempted liver-mass reduction pre-OLT died of bleeding and pulmonary emboli. Native liver weight was 10 to 20 kg. Posttransplantation immunosuppression consisted of cyclosporine or FK506, azathioprine, and steroids (discontinued at 3 months). Morbidity included biliary stricture (2 patients), revision for bleeding and hepatitis (1 patient), pneumothorax and subphrenic collection (1 patient), and tracheostomy (1 patient). One patient died of lung cancer 6 years posttransplantation. Both patient and graft survival rates are 87.5% (follow-up, 3 months to 9 years). Of 15 patients who underwent OLT alone, only 1 patient needed a kidney transplant 4 years after OLT. Kidney function has remained satisfactory in the other patients despite the use of cyclosporine or FK506 (last follow-up creatinine level, 1.55 mg/dL; range, 0.80 to 2.85 mg/dL). OLT had a dramatic impact on daily quality of life, enabling these patients to go back to a fully active life style. OLT offers the chance of a definitive treatment in patients with extensive, small, diffuse PLD that has evolved into severely handicapping hepatomegaly. In contrast to previous studies, combined liver and kidney transplantation is rarely needed. Patient symptoms and chances of definitive palliation offered by OLT must be balanced against the risks of transplantation and lifelong commitment to immunosuppression.

Lisa Capaldini, a physician who treats patients with HIV-related fatigue, discusses symptoms, diagnosis techniques, and treatments of depression, anemia, and various other roots of fatigue in HIV-positive patients. Biochemical depression, caused by abnormal levels of serotonin and norepinephrine in the brain, is easily misdiagnosed or overlooked. Physical and emotional symptoms of depression mirror common effects of HIV such as exhaustion, anger, and irritability. Knowing the history of depression prior to HIV infection, including previous drug abuse and family history of depression, will help to diagnose fatigue. Dr. Capaldini recommends antidepressants provided the condition is properly diagnosed and the side effects are not harmful to the patient. Selective serotonin reuptake inhibitors (SSRI), the most frequently prescribed antidepressants, can cause short term sexual dysfunction. Bupropion and Wellbutrin can be prescribed to avoid this side effect. Psychotherapy can be effective if therapists are familiar with HIV disease and can distinguish between symptoms brought on by behavior, addictive habits, or pre-existing depression. Consideration also must be given to drug interactions, particularly with the antiretrovirals ritonavir and delavirdine, which can cause seizures or disturb cardiac rhythm. Anemia is most noticeable after physical exertion, and symptoms are more evident based on the increased rate that red blood cells move out of the normal range. To determine the course of treatment, physicians need to clarify the cause of anemia. Anemia can be caused by drugs, vitamin deficiencies, or other nutritional problems. Adrenal insufficiency, methemoglobinemia, and malnutrition are also causes of fatigue. Diagnosing fatigue due to hepatitis B or C, rather than HIV, can be achieved by measuring hepatitis levels and observing T cell counts and viral load. Dr. Capaldini suggests that proper diet and exercise prevent fatigue from getting worse.

We present the case of dual adult celiac disease and liver disease with portal hypertension (esophageal varices); a percutaneous liver biopsy was compatible with nonspecific reactive hepatitis. Clinically, celiac disease was characterised by poor response to a gluten-free diet, with the development of a biochemical cholestasis and marked malnutrition. Our patient died of cerebral hemorrhage, at the age of 50 years, without associated risk factors. The necropsy demonstrated the existence of a nodular regenerative hyperplasia of the liver, splenic atrophy, gelatinous transformation of the bone marrow, and lymphocytic colitis. We discuss the different types of liver disorders associated with celiac disease and the possible relation between nodular regenerative hyperplasia and celiac disease, based on immunologic mechanisms.
