results liver function tests in the healthy blood donors were within the normal range. the incidence rates of senv-d and senv-h in the 184 total blood donors were 10 (5.4%) (95% confidence interval (ci): 2.1% - 9.0%) and 32 (17.4%) cases (95% ci: 12.0% - 23.0%), respectively. senv-h/d co-infection occurred in 2 (1.1%) patients. the sera of 8/184 (4.3%) were positive for anti-hbc antibody but ne...
Abstract Background & aim: Occult hepatitis B virus infection in blood donors threats the safety of the blood supply. It is characterized by detection of low viral DNA in the serum subjects who have negative test for Hepatitis B surface antigen (HBsAg). The aim of this study was to assess the prevalence of occult hepatitis B virus infection among HBsAg negative and HBcAb positive in blood ...
results of 45 patients, 4 (8.9% [95% ci: 4.4-15.6]) had detectable genomic hcv-rna in their pbmc specimens. hcv genotypes were determined in the pbmcs of these subjects showed that 2 (50.0%) subjects with occult hcv infection had hcv subtype 3a, and 2 (50.0%) had hcv subtype 1b. conclusions this study found that 8.9 % of the iranian candidates for liver transplant with cryptogenic cirrhosis had...
Background and Objectives: Hepatitis B virus (HBV) infection is a major public health problem worldwide. Islamic Republic of Iran is located in mesoendemic region (prevalence 2%-7%). The aim of this study was to assess prevalence of chronic HBV in Iran according to demographic characteristics. Methods: Medline, Embase, Science Citation Index Expanded, Ovid, Google Scholar, IranMedex, SID, Ma...
objective: occult hepatitis b infection is a form of hepatitis in which despite of absence of detectable hbsag, hbv-dna is present in peripheral blood of patients. this clinical form of b hepatitis creates some problems for the iranian blood transfusion services. therefore, the aim of this study was the evaluation of status of occult hepatitis b infection in the rafsanjanese blood donors. mate...
Background: With due attention to the prevalence of thalassemia in Iran and patients' importunate needs for blood intake, this study aimed to inspect contaminations due to repeated blood transfusion which does not sift in blood donation. One such contamination is cytomegalovirus infection, which is an important pathogen in immunosuppressive patients or receivers of transplanted organs. Methods...
Background: Hepatitis is among the major health problems, especially in developing countries. During past decades, the association between type of blood group (ABO) and hepatitis B and C virus has always been discussed. This study was designed to investigate the possible association between type of ABO blood group and chronic hepatitis B and C infection. Methods: In the present analytical stud...
Background: Geographical distribution of ABO blood groups affects by race, ethnicity, migration and some infectious agents, such as Plasmodium species. P. falciparum is the major causative agent of death in malaria that can affect ABO blood group distribution in different populations. Therefore, the objective of the current study was to determine the effect of p. falciparum on ABO blood group d...
Background: Bilirubin encephalopathy is a clinical syndrome, associated with bilirubin toxicity in the central nervous system, resulting in chronic and permanent sequelae. It has been estimated that approximately 60% and 80% of term and preterm newborns develop jaundice in the first week of life, respectively. In the present study, we aimed to determine the prevalence, morbidity, and mortality ...
seven hundred and sixty-eight blood samples of pregnant cattle from four holstein dairy herds that are farmed in the vicinity of tehran were used to evaluate the seroprevalence of neospora caninum infection by enzyme-linked immunosorbent assay (elisa). two hundred and ninety-eight of the 768 blood samples (38.8%) were positive for this infection. the prevalence of infection in the herds varied ...
