background: sen virus (senv) is the latest virus proposed as a cause of unknown hepatitis cases. among nine detected genotypes of the virus, genotypes d and h are more frequent in hepatitis cases of unknown origin. the aim of this study was to determine the frequency of senv-d and senv-h genotypes in the sera of healthy individuals and hepatitis b and c patients. methods: totally, 200 serum sam...

BACKGROUND Hepatitis D virus (also known as hepatitis delta virus) can establish a persistent infection in people with chronic hepatitis B, leading to accelerated progression of liver disease. In sub-Saharan Africa, where HBsAg prevalence is higher than 8%, hepatitis D virus might represent an important additive cause of chronic liver disease. We aimed to establish the prevalence of hepatitis D...

Background and aims: Hepatitis B vaccination is the most successful way to prevent the virus infection. Serum concentration of vitamin D has recently been proposed as a novel predictor of response to antiviral treatment in chronic hepatitis infection. The main target of this paper was to review the recent knowledge regarding the association between obesity and vitamin D level and immune respons...

BACKGROUND Hepatitis D virus (HDV) is a defective RNA virus that depends on the hepatitis B surface antigen (HBsAg) of hepatitis B virus for its replication, developing exclusively in patients with acute or chronic hepatitis B. There are little data regarding the routes of HDV transmission in Iran. The risk factors for HDV infection in Iran are blood transfusion, surgery, family history, Hejama...

We read with interest the paper entitled “Prevalence of Hepatitis D Virus Infection among Hepatitis B Virus Infected Patients in Qom Province, Center of Iran” by Ghadir et al. (1) which was performed to determine the prevalence of hepatitis D in the general population of Qom province and the potential risk factors for acquiring HDV. They found 48 subjects (1.3%) suffered from hepatitis B and on...

Hepatitis D, also referred to as hepatitis D virus, or delta virus (HDV) is considered be a subviral satellite because it can propagate only in the presence of B (HBV) (WHO, 2020). There are uncertainties about epidemic patterns HDV infection and its contribution burden liver disease. defective that completes life cycle with (HBV). The HBV super-infection has been one most severe forms chronic ...

conclusions the main and frequent hbv genotype among azerbaijani patients with chronic hepatitis b virus infection was genotype d followed by genotype a. results the mean age of patients was 35.9 ± 11.7 years (19-66). of 103 patients, 72 (69.9%) were male. in the present study, the predominant hbv genotype was d (93.2%) followed by genotype a (5.8%) and concurrent infection with a and d genotyp...

results there were no significant differences in baseline characteristics between two groups except serum ast level. complete evr rate at week 12 in the vitamin d group was significantly higher than the controls (100% vs 84.4%; p = 0.023) whereas this figure was not significant when genotypes 1 and 4 or 2 and 3 in the test group were compared to those of the control (100% vs 86.7%; p = 0.19 and...
