Forty-one Egyptian schoolchildren (36 boys and five girls; age, 12-16 years) who were heavily infected with Schistosoma mansoni were studied. Symptomatic subjects had swimmer's itch and hematochezia. Hepatomegaly was found in 39 and splenomegaly in 31 children. All subjects had eosinophilia, 13 had anemia, 31 had elevated levels of serum globulins, and nine had elevated levels of alkaline phosphatase. All but one subject had antibody to hepatitis A virus, and 26 had antibody to hepatitis B core antigen, antibody to hepatitis B surface antigen, or both. Oxamniquine was given in single daily doses of 20 mg/kg of body weight for either two or three days and cured 50% and 85%, respectively, of subjects treated; ova excretion was reduced by 86%-93% for up to 12 months. Morbidity was associated with heavy S. mansoni infection. Therapy with oxamniquine was safe and efficacious.

A study of 90 asymptomatic hepatitis B surface antigen (HBsAg) carriers in Jerusalem showed a predominance of males over females (4:1) and of North African Jews over Jews of European or American Origin. The predominance of males remained apparent, but was not significant, when origin was controlled. Possible sources of infection were contact with jaundiced patients (29%), dental treatment (58%) and drug addiction (8%). Fifty-one percent had hepatitis B core antibody (anti-HBc) of the IgM class, 2% had hepatitis B e-antigen (HBeAg), 94% hepatitis B e-antibody (anti-HBe) and 93% had hepatitis A antibody (anti-HAV). Fourty-two percent had donated blood at least once prior to the detection of the carrier state. Fifty-five percent of 128 asymptomatic family contacts had evidence of hepatitis B virus infection. Minor abnormalities in liver function tests were found in 22% of the carriers and splenomegaly in 11%. Of ten liver biopsies performed in these cases, one had chronic active hepatitis, five had minimal histological changes, and four were normal.

Hepatitis B e antigen (HBeAg) was detected by agar gel diffusion in the serum of four Ugandan adults (three patients with tropical splenomegaly syndrome and one healthy adult) who did not have detectable hepatitis B surface antigen (HBsAg) by radioimmunoassay. Two of them had antibody to hepatitis B core antigen, and the other two had antibody to HBsAg. Detection of HBeAg by a relatively insensitive immunodiffusion test in the absence of HBsAg detectable by a sensitive radioimmunoassay suggested that production or removal of these two antigens may occur independently.

Persons with hemophilia or other HIV-1 risk factors may be more likely to have idiopathic CD4+ T-lymphocytopenia (ICL). We determined the frequency of ICL in prospectively followed cohorts of HIV-1 seronegative hemophilic men and seronegative female sex partners of HIV-1 infected hemophilic men, and examined factors potentially associated with ICL. Seven of 304 (2.3%) seronegative hemophilic men and one of 160 (0.6%) female partners met the ICL definition, but the condition resolved for two of the men and for the sole female partner. All five men with persistent ICL had lymphocytopenia (< 1,200 total lymphocytes/microliters) and < 300 total CD4+ lymphocytes/microliters; only one had a low CD4+ percentage. On the most recent measurement, 14.5% of the 304 seronegative hemophilic men had lymphocytopenia. Compared with matched hemophilic controls, men with persistent ICL more often had a history of liver disease (3/5 cases, 0/21 controls, P = 0.007) or splenomegaly (3/5 cases, 4/21 controls; P = 0.04), but not severe hemophilia, greater clotting factor concentrate exposure, high alanine aminotransferase levels, hepatitis B virus antigenemia, or detectable hepatitis C virus RNA in plasma. All five cases and 20/21 controls had antibodies to hepatitis C virus present in their serum. In this cohort of hemophilic men, ICL was related to lymphocytopenia associated with liver disease rather than selective loss of CD4+ lymphocytes.

We review the charts of the hospital with diagnostic of acute viral hepatitis. We classified them using serologic markers in hepatitis B (60 patients), hepatitis A (27 patients) and C (4 patients). Fatigue, anorexia, fever, chills and lymphadenopathy where more common in hepatitis A. Arthralgias, pruritus and rash where more common in hepatitis B. Bilirubin levels where higher in patients with hepatitis B (10.3 = -6.04 S.E:0.80) and C (9.7 +/- 4.09 S.E:1.24) compared with hepatitis A (6.7 +/- 6.04 S.E:0.80) p < 0.01 and p < 0.05. Alamine-Aminotransferase (ALT) levels where higher in patients with hepatitis B (1.918 +/- 1.099 S.E:215.5) and hepatitis A (1879 +/- 1.099 S.E:215.5) and lower in hepatitis C (988 +/- 764 E.E:382) p < 0.05. Abdominal Ultrasound reveal splenomegaly in 45% and 50% of patients with hepatitis A and C and only in 15% of patients with hepatitis B. Changes in gallbladder wall where found in 50% of patients with hepatitis A. 3.3% of patients with hepatitis B and 75% of patients with hepatitis C developed chronic infection.

A multicenter longitudinal study was performed to assess the survival of hepatitis B surface antigen positive compensated cirrhosis, primarily in relation to hepatitis B virus replication and hepatitis delta virus infection, and to construct a prognostic index based on entry characteristics. This cohort study involved nine university medical centers in Europe. Three hundred and sixty-six Caucasian HBsAg positive patients with cirrhosis who had never had clinical manifestations of hepatic decompensation were enrolled and followed for a mean period of 72 months (6 to 202 months). Inclusion criteria were biopsy-proven cirrhosis, information on serum hepatitis B e antigen and antibody to hepatitis D virus at the time of diagnosis and absence of complications of cirrhosis. At entry 35% of the patients were HBeAg positive, 48% of the patients tested were HBV-DNA positive and 20% anti-HDV positive. Death occurred in 84 (23%) patients, mainly due to liver failure (45 cases) or hepatocellular carcinoma (23 cases). The cumulative probability of survival was 84% and 68% at 5 and 10 years, respectively. Cox's regression analysis identified six variables that independently correlated with survival: age, albumin, platelets, splenomegaly, bilirubin and HBeAg positivity at time of diagnosis. According to the contribution of each of these factors to the final model, a prognostic index was constructed that allows calculation of the estimated survival probability. No difference in survival of hepatitis D virus infected and uninfected patients was observed. Termination of hepatitis B virus replication and/or biochemical remission during follow up correlated with a highly significant better survival. These data show that in compensated cirrhosis B, hepatitis B virus replication, age and indirect indicators of poor hepatic reserve and established portal hypertension significantly worsen the clinical course of the disease, whereas hepatitis D virus infection does not influence the prognosis. The highly significant improvement in life expectancy following cessation of hepatitis B virus replication and biochemical remission favors antiviral therapy in those patients with a guarded prognosis, as estimated by a prognostic index.

A total of 471 Israel Defense Forces (IDF) blood donors identified as hepatitis B virus (HBV) carriers were examined a few months after blood donation. When compared to the general population of IDF blood donors the HBV carriers were older, belonged to certain ethnic groups and were predominantly males. Physical examination revealed minimal findings: 1 (0.3%) had splenomegaly and 5 (1.6%) had hepatomegaly. Fifty-two individuals (11.1%) had elevated liver enzymes. E antigen was present in 3.2% of HBV carriers, 94% had anti-e antibodies and 1.9% had anti-delta antibodies. Of 258 carriers tested for HBV DNA, 29 (11.2%) were positive. Abnormal liver enzymes were significantly associated with the presence of e antigen as well as with the presence of HBV DNA.

In order to examine the character and phases of injury to the nervous system in HIV infection, 207 persons were observed. In 100, antibodies to the virus and to its separate proteins were discovered by immunofermentation analysis (IFA) reaction and by Western blot test. In 67, first phases of acute inflammation asymptomatic of persistent generalized lymphadenopathy were registered; and in 33, other ailments were found. In this group, which consisted of 74 men and 26 women aged 18-45, 91 were citizens of the Community of Independent States (15 of whom had served in the military) and 9 were citizens of other countries (4 had seen military duty). 75% of cases contracted the infection via sexual transmission. The control group comprised 65 seropositive people at the first screening confirmed by IFA but negative or doubtful by Western blot. Clinical laboratory and special psychological investigations were carried out using a 16-factor personality questionnaire and standard personality analysis methods. Generalized lymphadenopathy was found in 78%, hepatomegaly in 69%, chronic infection of the upper respiratory tract 67%, dermatological pathologies 33%, acute infections 32% (syphilis, hepatitis B), splenomegaly 20%, diarrhea and loss of more than 10% of body mass 11%. There was significant decrease of T-helper cells in 82.8%, in the correlation of the quality of T helper cells and T suppressor cells in 72.4%. In 67 persons who were in the second stage of HIV infection, there was a high frequency of pathological psychological symptoms. According to the personality scale, 60% had schizoid signs, 50% had depression, 40% had psychopathy, 30% had psychasthenia, and 20% had paranoia. When 33 persons in the second and third phase of the disease were measured, schizoid signs increased to 85.7%, depression to 78.6%, psychopathy to 57.1%, psychasthenia to 71.4%, and paranoia to 64.3%. In the first phases of the disease mainly hypochondria, depression, and hysteria predominated, and as the disease progressed, psychopathy, paranoia, psychasthenia, schizoid signs, and mania rose.

Acute splenic sequestration, a well recognized complication of the various sickle cell syndromes, is characterized by increasing splenomegaly and a sudden fall in hemoglobin concentration. In this article, the authors describe a 21-year-old woman with previously undiagnosed hemoglobin SC disease whose initial presentation was that of acute, severe splenic sequestration. Despite the severity of her illness, prompt diagnosis and appropriate therapy led to a complete recovery. The splenic sequestration in this case was apparently exacerbated by a recent hepatitis B infection. To date, this presentation of hemoglobin SC disease has not been described in the medical literature.

Use of long-term total parenteral nutrition (TPN) is often presumed to be associated with serious hepatic dysfunction. In this retrospective study, we reviewed the complete charts of patients who had received TPN for more than 2.5 years, starting in infancy or childhood, for evidence of liver dysfunction. There were 16 male and 10 female patients with a total of 254.5 patient years on TPN. Seventeen patients have been on TPN since birth or early infancy. Thirteen of 26 patients derive > or = 90% of their calorie intake from TPN. Six patients had hepatomegaly; two of them also had splenomegaly. Twenty-one patients had normal transaminases, nine have had past episodes of raised enzymes ranging from 2.5 to 7.5 times normal. Seventeen patients always had normal bilirubin levels, five had past episodes of hyperbilirubinaemia, while four patients had persistently raised bilirubin levels (range 1.5-20.7 g/dl). Alkaline phosphatase was normal for age in all patients except two. Hepatic synthetic function, as measured by albumin, pre-albumin levels and prothrombin time, was within the normal range in all patients except one. Liver biopsies were performed in eight patients. Two biopsies showed cirrhosis, one showed chronic active hepatitis (CAH) with cholestasis, two patients had fibrosis, one showed cholestasis and two biopsies were normal. One patient with cirrhosis and one with CAH were positive for hepatitis C antibody. Another asymptomatic patient was positive for hepatitis B. Only the patient with CAH had hepatic decompensation. We conclude that clinical hepatic failure is uncommon in our group of patients on long-term TPN for 2.5 years or more. Cirrhosis and fibrosis, when found, could not be solely attributed to TPN.
