RESUMO

BACKGROUND: Early detection of hepatocellular carcinoma is very important in the treatment which is feasible. Alpha-fetoprotein plus ultrasound in surveillance programs is controversial. GP73 is a protein. Golgi increase significantly in the sera of patients with hepatitis B virus and HCV-related HCC, providing a marker for its early detection. The aim is to detect serum Golgi protein 73 (GP73) in patients with cirrhosis and with hepatocellular carci-noma (HCC), and to determine its sensitivity and specificity as a screening tool for the detection of HCC. METHODS: A case control study was conducted in four groups of 32 participants each: 1- healthy controls; 2 - chronic liver disease; 3 - decompensated liver disease; 4 - HCC group. The HCC group included 25 males and 7 females with a mean age of 58 ± 7 years, fulfilling diagnostic criteria for HCC. GP73 was estimated in the serum samples taken from the HCC group and control groups. RESULTS: GP73 was elevated in patients with HCC and liver cirrhosis. Serum level was very high in HCC patients (p < 0.01) when compared with the other studied groups. GP73 had a sensitivity of 96.9% and specificity of 96.9% at a cutoff value of 17.5 ng/mL when compared with α-fetoprotein (AFP) that showed a sensitivity of 75% and specificity of 92% at a cutoff value of 9.4 ng/mL. CONCLUSIONS: GP73 can be used as a screening tool for the detection of HCC with higher diagnostic performance than AFP.

RESUMO

The transmission rate of intra-familial hepatitis B virus (HBV) and mode of transmission were investigated in north eastern Egypt. HBV infection was investigated serologically and confirmed by molecular evolutionary analysis in family members (N = 230) of 55 chronic hepatitis B carriers (index cases). Hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) prevalence was 12.2% and 23% among family members, respectively. HBsAg carriers were prevalent in the age groups; <10 (16.2%) and 21-30 years (23.3%). The prevalence of HBsAg was significantly higher in the family members of females (19.2%) than males (8.6%) index cases (P = 0.031). HBsAg and anti-HBc seropositive rates were higher significantly in the offspring of females (23%, 29.8%) than those of the males index cases (4.3%, 9.8%) (P = 0.001, 0.003), as well as higher in the offspring of an infected mother (26.5, 31.8%) than those of an infected father (4.7%, 10.5%) (P = 0.0006, 0.009). No significant difference was found in HBsAg seropositive rates between vaccinated (10.6%) and unvaccinated family members (14.8%). Phylogenetic analysis of the preS2 and S regions of HBV genome showed that the HBV isolates were of subgenotype D1 in nine index cases and 14 family members. HBV familial transmission was confirmed in five of six families with three transmission patterns; maternal, paternal, and sexual. It is concluded that multiple intra-familial transmission routes of HBV genotype D were determined; including maternal, paternal and horizontal. Universal HBV vaccination should be modified by including the first dose at birth with (HBIG) administration to the newborn of mothers infected with HBV.
