The study was carried out to investigate some immunogenetic aspects in Basrah patients with hepatitis B virus infection.

The study included 205 individuals of both sexes, comprising 155 individuals as the patients group, consisting of 122 males, 33 females with age ranged 3-80 years and 50 individuals randomly selected as control groups consisting of 29 males, 21 females with age ranged 20-50 years. The total markers of HBV (HBsAg, anti-HBs, HBeAg, anti-HBe, Total anti-HBc and IgM Anti-HBc) were detected by application of ELISA technique.

The results showed a positive sera of 151 patients, thus a total of 155 individuals divided into usual markers (78.72 %) and unusual markers (18.7 %) in addition to (2.58 %) of individual groups of vaccinated and non-infected.

Usual markers of patients were divided into eight studied groups including : Incubation ( 2.58 %),Active acute (3.87 %) , Acute (13.55 %) , Active chronic ( 1.29 %) , chronic ( 5.17 %) , Inactive HBsAg Carrier (44.52 %),HBsAg-negative patients ( 5.8 %) and liver cancer (1.94 %) groups.

According to annual statistical the prevalence of HBV infection which was observed in public health department and blood bank center at period 2005-2010 were 1.36 % and 0.27 %, respectively. The present study showed that 78.14 % of the males in both markers more susceptibility to the infection with highly significant differences (P < 0.001) than females (21.86 %).

From these, Married patients (61.59%) showed significantly elevated (P < 0.05) than single patients (38.41 %).

Also (44.37 %) uneducated patients, (97.35 %) non-vaccinated patients and (94.7 %) non- treated patients were more susceptible to the infection with highly significant differences (P < 0.001) in usual markers and unusual markers, respectively. Furthermore, the age ranges of the infected patients varied between 3 and 80 years .The age period between (20-29) and (30-39) were significantly prone to the infection (P < 0.05).

In contrast, the age period (10-19) years was significantly decreased to the infection (P < 0.05).

Interestingly, both markers of patients showed no significant differences among different symptoms.

Big portion (33 %) of both markers of patients acquired HBV infection through unknown routes of infection, particularly in Male patients (P < 0.001).

Blood transfusion and contacting with HBV Patients form the main probable routes of transmission (25 %) ; significant differences (P < 0.001). Analysis of HLA complex was carried out for 50 patients with chronic HBV infection and 50 healthy control persons to have a clearer integrative idea on the impact of HLA (class II ,HLA- DRB1 plus ) on the susceptibility and resistance to HBV infection.

Alleles DRB1 * 3 (P = 0.001) sub-allele DRB1 * 030101 (P = 0.007) and DRB1*11 (P = 0.014) were might be responsible for susceptibility.

Alleles DRB1 * 01(P = 0.006), sub-allele DRB1* 070101(P = 0.015) and DRB1* 13 (P = 0.013) were might be responsible for resistance. On the other hand this study determinated the genotype of HBV in Basrah patients for the first time.

The genotype D was the only detected type found in all patients. sFas levels (Mean ± SD ) showed highly significant differences (P< 0.001) among studied groups.

Chronic (2.34 ± 0.69), Inactive HBsAg carrier (1.08 ± 0.36) and liver cancer (2.69 ± 0.35) groups had elevated mean values in comparison with healthy control (0.64 ± 0.12).

Also sFasL levels (Mean ± SD) showed significantly elevated (P=0.003) in chronic (0.1 ± 0.02) and significant differences (P = 0.02) in Inactive HBsAg carrier (0.08 ± 0.03) in comparison with healthy control (0.06 ± 0.01). Liver function tests were more significantly elevated (P < 0.001 or 0.05) in liver cancer, unusual markers and chronic groups than other groups.
