Circulating soluble antigens and antibody in schistosomiasis.

Some patients with Schistosoma mansoni and S. haematobium infections were shown to have soluble schistosomal antigen in their plasma. Antibody to this antigen and to other antigens of adult worms were also present. These findings may be relevant to schistosomal-related immune-complex disease, especially the nephrotic syndrome.

Hepatitis C virus genotyping versus serotyping in Egyptian patients.

BACKGROUND: The RNA genome of hepatitis C virus (HCV) displays extensive sequence variation. In this study, serotyping and genotyping techniques were applied to assess this variability by comparing the performance of the serotyping assay with a panel of well-characterized HCV strains isolated from chronic active hepatitis (CAH) patients. PATIENTS AND METHODS: 60 serum samples from CAH patients were analyzed. All isolates were genotyped by a line probe assay and the results of genotyping and serotyping were evaluated. RESULTS: The overall sensitivity of the serotyping and genotyping techniques was 81.16% with a concordance of 73.3%. Type 4 was detected in 73.3% of cases and it was highly heterogeneous. CONCLUSION: Type 4 HCV is the most prevalent type in Egyptian CAH patients and there is a high concordance between the results of serotyping and genotyping techniques.

The relationship between uncomplicated schistosomiasis and hepatitis B infection.

Clinical and laboratory findings and hepatitis B virus (HBV) markers were compared in 105 patients with uncomplicated schistosomiasis mansoni, schistosomiasis haematobium, or both infections. 34 (32%) had HBs antigen (Ag); 51 (49%) had anti-HBs and/or anti-HBc; 20 (19%) had no markers for HBV. In comparison with the non-HBV-infected group, the group with HBsAg had more complaints of nausea and vomiting, and higher mean values for serum bilirubin and aspartate aminotransferase, and were less likely to complain of loose stools. In comparison with the non-HBV-infected group both groups having HBV markers were older, more likely to have received prior therapy (parenteral therapy in particular) for schistosomiasis, less likely to complain of blood in their stools, and more likely to have higher serum total proteins, albumin, globulin, and alanine aminotransferase. This study supports two mechanisms which could cause an association between HBV infection and schistosomiasis: (i) self-selection by patients with schistosomiasis seeking medical care for symptoms due to HBV infection and (ii) iatrogenic infection with HBV during parenteral treatment for schistosomiasis. It also suggests that much of the clinical morbidity ascribed to uncomplicated chronic schistosomiasis may be caused by a concomitant occult HBV infection.
