“…Furthermore, the seroprevalence of hepatitis A in the general population of Tehran, Golestan and Hormozgan provinces did not differ between males and females (15). Moreover, same anti-HAV seropositivity among males and females has been observed in other countries such as Croatia (23). These could reflect similar risk factors for infection between both genders.…”

Background: Hepatitis A Virus (HAV) is the most common cause of acute viral hepatitis worldwide, mostly in developing countries.Objectives: This population-based survey was performed to investigate HAV seroprevalence in Mashhad, northeast of Iran. Patients and Methods: A cross-sectional study was performed on 1563 randomly selected individuals from general population of Mashhad, Iran, between May to September 2009. Serum samples were tested for total anti-HAV antibody using an enzyme-linked immunosorbent assay (ELISA) kit. Data was analyzed using SPSS ver. 18.0 by Chi-square and student t tests. Results: Seroprevalence of HAV infection was 69.6% (95% CI: 67.3-71.9%) with no difference between males and females. Anti-HAV seropositivity increased with rising age from 9.4% in subjects younger than five years to 100.0% in individuals older than 65 years old (P < 0.001). Conclusions: As it was previously reported by the World Health Organization (WHO) on HAV infection in the country, this study revealed a high prevalence of HAV infection in Mashhad city, Northeastern Iran.

“…As this disease is x-linked, 79.9% of all patients were male who could superimpose our results (76.2% of seropositive cases were male) in opposite of some related studies (12,13) but similar to this study in Thailand (14). In addition, thalassemia patients were 5 years younger than hemophilia patients with higher prevalence of HAV infection.…”

Background: Hepatitis A and E virus (HAV and HEV) infections are acute and self-limited diseases that usually spread through oral-fecal route. Also, blood transfusion as a possible route of entrically transmitted hepatitis has been suggested. Hemophilia and thalassemia patients are highly at risk of transfusion-transmissible viruses (HBV, HCV, and HIV). Any superimposed infection with other viral hepatitis (in particular hepatitis A) cause active liver failure in hemophilia and thalassemia patients. Objectives: The aim of this study is to consider seroprevalence of anti HAV and HEV antibodies (Ab) in thalassemia and hemophilia patients with chronic hepatitis C in Iran. Patients and Methods:In a cross-sectional study and under general census sampling, sera of 219 thalassemia and hemophilia patients infected with HCV were examined in Tehran Hepatitis Center (THC) between 2009 and 2010. Enzyme-linked immunisorbentassey (ELISA) was done to observe anti HAV and HEV IgG Ab. Patients were chosen from all provinces of Iran. Results: Anti-HAV IgG antibodies were observed more frequently in thalassemia patients (60/64; 93.8%) than in hemophilia patients (104/155; 67.1%, P < 0.001). The seroprevalence of both antibodies increased with age. Among thalassemia patients, there was no significant association between HAV seropositivity and other variables, but in hemophilia group, seropositive patients were significantly older than seronegative group (P < 0.05). Totally, anti HEV Ab (1/64; 1.6% thalassemia and 5/155; 3.2% hemophilia) was seropositive in six patients. There was no significant association between HEV infection and other variables in thalassemia patients, however, in hemophilia patients, HEV positive ones were significantly older than HEV negative group (P=0.01). Conclusions: Vaccination of non-immune individuals against HAV infection in high risk groups especially hemophilia and thalassemia patients is recommended. Results did not show any differences about seroprevalence of HEV among Iranian general population.

“…HAV infection is a considerable hygienic problem in developing countries with low socioeconomic conditions, especially among some specific populations such as injection drug abusers and patients with clotting factors disorders. This infection is transmitted person to person through fecal-oral route ( 3 , 4 ). Seafood can be a common HAV infection source if not cooked well.…”

Background:Enterically-transmitted acute viral hepatitis is caused predominantly by hepatitis A virus (HAV) and hepatitis E virus (HEV). The prevalence of HEV and HAV infections varies in different geographical regions.Objectives:This study was conducted to determine the prevalence of HEV and HAV infections among Iranian healthy individuals in southern Iran.Patients and Methods:Totally, 1030 samples were collected from healthy subjects in schools, those referred to tertiary outpatient clinics and health centers in Shiraz between November 2011 and May 2012. Their ages ranged between six months and 95 years. The presence of total anti-HAV and anti-HEV immunoglobulin M (IgM) in plasma was assessed by ELISA.Results:The results showed that 66.2% and 0.6% of the general population in this area were positive for total anti-HAV and IgM antibodies by ELISA, respectively. As seen, 13.4% and 0.9% were positive for total anti-HEV and IgM antibodies, respectively. The difference in total anti-HAV and anti-HEV antibodies was significant among the age groups (P < 0.001).Conclusions:This study showed that the prevalence rates of HAV and HEV antibodies were positively correlated with age. The results demonstrated that the infection with these two viruses in the region was high and some high-risk individuals including females at child-bearing age were more susceptible. HAV vaccination could be recommended for antibody-negative adults.
