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.

Clinicoimmunological features of viral hepatitis A and B (VH A and VH B) were studied in residents of unfavorable (from the environmental standpoint) regions. 180 VH A, 86 VII B patients were examined. Clinical picture of VH was characterized by predominance of more severe forms, frequent occurrence of cholestatic variant of VH, high rate of protracted and recurrent (in VH B) course of VH, hepato- and splenomegaly of long duration. The immunologic status was characterized by more pronounced T-lymphopenia, noticeable imbalance of T-helpers and T-suppressors, decrease in the level of immunoglobulins, as well as in phagocytic activity of neutrophilic granulocytes and monocytes in peripheral blood. The use of adaptogens and antioxidants in multimodality treatment promotes rapid normalization of clinicoimmunological parameters in VH.

It is well known that cytomegalovirus infection is often accompanied by hepatitis, but there have been few comparative studies with respect to clinical features of cytomegalovirus-associated hepatitis and other acute viral hepatitides. In the present study, clinical and pathological features of 11 acute sporadic cytomegalovirus hepatitis infections in previously healthy adults were compared with those of 45 acute sporadic viral hepatitis, including type A, type B and type C. As a result, the characteristics of cytomegalovirus hepatitis were a long-lasting fever, splenomegaly, atypical lymphocytosis, a mild transaminasemia, a low ratio of alanine aminotransferase level to lactate dehydrogenase level, and mild hepatic histopathological changes.

Hemophagocytic lymphohistiocytosis, a variant of histiocytosis, is characterized by an uncontrolled activation of the cellular immune system, including hepatic mononuclear phagocytic cells. Abdominal ultrasound findings in children are evaluated in this disease. We present six pediatric cases, two with familial and four with sporadic hemophagocytic lymphohistiocytosis, examined by abdominal sonography. Three signs were frequently observed: thickening of the gallbladder wall (all cases), increased periportal echogenicity (four cases), and enlarged lymph nodes in the porta hepatis (four cases). Hepatomegaly, splenomegaly, and ascitic fluid may also be found. These imaging findings are not specific and may be seen in viral hepatitis. However, once hepatitis is excluded, they may suggest the diagnosis of hemophagocytic lymphohistiocytosis in a critically ill child. A bone smear must be done to establish the diagnosis.

Diagnostic difficulties of Gaucher disease, a disorder resulted from a deficient activity of glucocerebrosidase is reported. Gaucher disease was described in the 16 year old male, 5 years after manifestation of the very first symptoms (fracture and osteomyelitis). At the age of 14, the cirrhosis due to viral hepatitis accompanied with splenomegaly was diagnosed. This findings was not associated with the earlier osseous disorders. Histopathologic examination of the removed spleen facilitate the diagnosis. The second case refers to 20 year old female. Clinical symptoms and additional test pointed to malignant neoplasm of thyroid, the reproductive organs or cancer of indistinguishable primary focus with metastases in the liver. Trepanobiopsy of bone marrow had made an accurate diagnosis possible, while determination of beta-glucosidase activity in peripheral white blood cells, chitotriosidase activity, and molecular investigations of gene specific to beta-glucocerebrosidase proved it.

Health questionnaires and parasitologic examinations of urine and stool were performed upon a stratified random sample of 10,899 individuals from 1,537 households in 27 rural communities in Menofia Governorate in Egypt in 1992 to investigate the prevalence of, risk factors for, and changing pattern of infection with Schistosoma sp. in the governorate. A subset, every fifth household, or 1,480 subjects, had physical and ultrasound examinations to investigate prevalence of and risk factors for morbidity. The prevalence of S. mansoni ranged from 0.3% to 72.9% and averaged 28.5%. The geometric mean egg count was 81.3 eggs/gram of stool. Age-stratified prevalence and intensity of infection was 30-40% and 60-80 eggs/gram of stool from the age of 10 onward; males had higher infection rates and ova counts than females in all age groups > 10 years old. Schistosoma haematobium was rare, being consequential in only 1 community. Risk factors for S. mansoni infection were male gender; age > 10 years; living in smaller communities; exposures to canal water; history of or treatment for schistosomiasis or blood in the stool; detection of splenomegaly by either physical or ultrasound; and ultrasound-detected periportal fibrosis (PPF). The more severe grades of PPF were rarely (21 of 1,450 examinations) detected. Risk factors for morbidity, i.e., ultrasound-detected PPF, were similar to those for infection. Schistosoma mansoni has almost totally replaced S. haematobium in Menofia. The prevalence of S. mansoni in rural communities remains high and average intensities of infection are moderate. The association of morbidity with schistosomal infection was variable and is obviously markedly influenced by both the frequent use of antischistosomal chemotherapy in communities in Menofia and by the prevalence of complications from chronic viral hepatitis in the population: hepatomegaly did not correlate with infection; PPF and splenomegaly, however, were related to S. mansoni infection in both individuals and communities.

The literature on the assessment of morbidity due to Schistosoma mansoni infection is updated. Imaging techniques such as ultrasonography, echodoppler cardiography, computerized tomography (CT scan) and magnetic resonance imaging (MRI) introduced a new perspective, and expanded our knowledge on morbidity. Three well-defined syndromes caused by schistosomiasis mansoni have been described: the stage of invasion, acute schistosomiasis (Katayama fever), and chronic schistosomiasis. Complications of the acute and chronic syndromes have also been reported: pulmonary hypertension, neuroschistosomiasis, association with Salmonella, association with Staphylococci, viral hepatitis B, glomerulonephritis. In most individuals with hepatosplenic schistosomiasis the spleen is increased in size. Hepatosplenic schistosomiasis can, however, occur without splenomegaly. The definition of hepatosplenic schistosomiasis in endemic areas as the finding of S. mansoni eggs in the stools in an individual with hepatosplenomegaly is not satisfactory anymore. Many aspects of morbidity are expected to change after schistosomiasis control. Some are expected to change quickly (worm burden, Salmonella bacteremia, hepatosplenic schistosomiasis in children) whereas others shall remain for years (pulmonary hypertension, glomerulonephritis, neuroschistosomiasis). Intestinal schistosomiasis in individuals with low worm burdens is very difficult to diagnose and therefore laborious to control.

The pathogenesis of thrombocytopenia in chronic hepatitis is not well known. This study evaluated the relationship between liver injury, serum thrombopoietin, splenomegaly and thrombocytopenia in chronic viral hepatitis. Two hundred and nine patients were enrolled, 85 with splenomegaly and 124 without. Thrombocytopenia was present in 71% and 23% of patients with or without splenomegaly respectively. In subjects with low platelet count, those with splenomegaly showed significantly lower platelet numbers than those without splenomegaly. The spleen size correlated with portal hypertension. An inverse correlation between spleen size and platelet count was observed (r = -0.54; P < 0.0001). In patients without splenomegaly, thrombocytopenia was associated with the grade of fibrosis; platelet counts were the highest in patients with fibrosis 0-2, lower in those with grade 3 (P < 0.008) and lowest in those with grade 4 (P < 0.05). These findings were independent of demographic and biochemical characteristics, hepatic necroinflammatory activity, portal hypertension and splenomegaly. Patients with normal platelet counts showed higher thrombopoietin levels than those with low platelet counts (P < 0.0001). An inverse correlation between thrombopoietin levels and fibrosis grade was observed (r = - 0.50; P < 0.0001). Median thrombopoietin levels were 58 and 27 pg/ml for fibrosis grade 0-1 and grade 4 respectively (P < 0.001). These data indicate that advanced hepatic fibrosis, causing an altered production of thrombopoietin and portal hypertension, plays the central role in the pathogenesis of thrombocytopenia in chronic viral hepatitis.

Schistosomiasis mansoni is a widespread parasitic disease in the Brazilian territory that affects over 8 million individuals. Hepatosplenic schistosomiasis is a serious clinical presentation of this disease, associated with splenomegaly, liver fibrosis, and portal hypertension, and is responsible for approximately 7% of schistosomotic patients. The surgical treatment of portal hypertension in schistosomotic patients has distinct features when compared with cirrhotic patients, mostly because hepatic function is preserved in schistosomotic liver disease. Therefore, when attempting to reduce the portal pressure, the surgeon must be aware that the surgery might interfere with hepatic perfusion, and consequently with hepatic function. The aim of this study was to report the results achieved with splenectomy, division of the left gastric vein, devascularization of great gastric curvature, and postoperative endoscopic variceal sclerosis, as a surgical option to esophageal varices in hepatosplenic schistosomiasis. A total of 111 patients were studied, and the following is a list of inclusion criteria: age >16 years, history of gastrointestinal (GI) bleeding, presence of esophageal varices on preoperative endoscopy, hematocrit >22% and prothrombin enzymatic activity >50%, negative viral hepatitis on serologic tests (anti-HBV and anti-HCV), and definition, after liver biopsy, of exclusive schistosomotic liver disease. The following list includes exclusion criteria used: presence of liver disease other than schistosomotic, history of alcohol abuse, and preoperative thrombosis of the portal vein. The rebleeding rate was 14.4% during a mean 30-month follow-up period; portal vein thrombosis was 13.2%, and there was a global mortality of 5.4%. Gastric varices were present in 46.9% of the patients; for those patients, a gastrotomy and running suture of the varices achieved an eradication rate of the varices of 75.6%. The degree of periportal fibrosis was also analyzed. Periportal fibrosis staging revealed that patients with class II or III liver fibrosis had a significant increased risk of recurrent GI bleeding when compared with patients with class I liver fibrosis. Despite the elevation on alanine aminotransferase (ALT) and aspartate aminotransferase (AST), most other liver function tests showed no alteration or were corrected after surgery. We conclude that splenectomy, division of the left gastric vein, devascularization of great gastric curvature, and postoperative endoscopic variceal sclerosis showed good results globally and should be considered as therapeutic options in the treatment of hepatosplenic schistosomiasis.

From August 1997 to January 2000, 172 children (< or = 14 years) with acute viral hepatitis were studied. Their clinical features, investigations and outcome were noted. Viral markers (IgM anti-HAV, IgM anti-HEV, HBsAg and anti-HCV) were measured by ELISA using commercial kits. The mean age of these children was 5.6 +/- 2.9 (range, 4 months to 14 years) with a male to female ratio of 120:52. Prodromal symptoms were present in 161 (94 per cent) and icteric hepatitis was diagnosed in 168 (98 per cent) cases. Splenomegaly was noted in 53 (31 per cent), ascites in 52 (30 per cent) and encephalopathy (ALF) in 56 (32.6 per cent) cases. Sixteen (31 per cent) children with ascites had spontaneous bacterial peritonitis (SBP). Fifteen (27 per cent) children with encephalopathy died. Viral markers were positive in 166 (96.5 per cent) and they were: A in 111 (64.5 per cent), E in 28 (16.3 per cent), B in 13 (7.6 per cent), A + E in 12 (7 per cent), A + E + C and A + C in one each. Mortality in acute liver failure was more when associated with SBP (100 per cent) than without (20 per cent) (p < 0.001). We conclude that HEV is the second most common cause of sporadic acute viral hepatitis in children. Atypical presentations, such as splenomegaly, ascites, and SBP were present in virtually one-third of cases. In cases of ALF, the presence of ascites and SBP depicts a worse outcome.
