Comparison between HBe antigen-negative patients and HBe antigen-positive patients with chronic hepatitis B infection in Benghazi, Libya

To determine the frequency of HBeAg-negative/anti-HBe-positive chronic hepatitis B in patients with chronic hepatitis B, in Benghazi, Libya, and to compare the epidemiological, biochemical, serologic and histologic features in HBe-Ag-negative patients and HBeAg-positive patients with chronic hepatitis B in these two groups of patients. One hundred and fifty HBsAg-positive patients with chronic hepatitis presented consecutively to the liver clinic, Al-Jamahiriya Teaching Hospital, Benghazi, between January 2002 and December 2003 were studied. The 150 patients were divided into two groups, according to their HBe status: group 1 consisted of 30 patients with serum HBeAg-positive group 2 comprised 120 patients with positive serum anti-HBe and negative serum HBeAg. Epidemiological features were assessed in all patients from their medical records. Serological tests for HBsAg, HBeAg and HBeAb were performed by ELISA techniques. HBV-DNA levels were performed by quantitative polymerase chain reaction. The two groups did not differ in sex distribution, and the average age was higher in patients who were HBeAg-negative. History of hepatitis in family members was more observed in the HBeAg-negative group [p=0.01]. No difference was observed between the two groups with respect to other risk factors and serum ALT levels at the time of diagnosis. The time course of ALT levels observed in patients during the 6 month follow up did not differ between the two groups [p = NS]. Cirrhosis and fibrosis were more common in patients with HBeAg-negative chronic hepatitis B group [p<0.05 for both parameters]. The frequency of HBeAg-negative chronic hepatitis B infection is high in Libya. This high prevalence rate has an impact on the natural history and prognosis of the disease in this part of the world

Seroprevalence of anti-hepatitis D antibodies in hepatitis B virus infected patients in Benghazi, Libya

Hepatitis D virus [HDV] infection is considered to be high in the Mediterranean basin. Data regarding this infection in Libyan population are scarce. The aim of the present study was to determine the seroprevalence of anti-HDV antibodies in hepatitis B virus [HBV] infected patients in Benghazi. The study population comprised one hundred thirty-eight patients with chronic HBV infection who were attending the liver clinic, Aljamahiriya Teaching Hospital, Benghazi. The diagnosis of HBV infection in those patients was based on repeatedly positive HBsAg in the serum with other laboratory and / or radiologic features of liver disease. All patients were tested for the presence of Anti-HDV IgM antibodies and Anti-HDV IgG antibodies using ELISA techniques. At the same time the level of HBV-DNA was measured using polymerase chain reaction [PCR] techniques for both Anti-HDV antibodies positive and negative patients. Fifteen patients were positive for anti-HDV IgG antibodies [10.8%] and none was positive for Anti-HDV IgM antibodies [0%]. The HBV-DNA levels were higher in HBV patients with Anti-HDV antibodies than in patients positive for Anti:HDV Anti- HDV antibodies [P=0.01]. HDV infection does not appear to be commonly prevalent in Libyan patients with HBV. In comparison to data from previous results from Mediterranean area, the seroprevalence of HDV in Libyan patients who were attending the liver clinic, Benghazi is considered to be intermediate
