Background. Relationship between blood groups and dermatologic diseases remains controversial and was not yet fully elucidated nor explained clearly. The aim of this study was to examine if any relation exists between different types of pemphigoid diseases and ABO blood group. Methods. In this case-control study, 159 pemphigoid patients and 152 healthy matched-controls were evaluated. All blood...

background: determining of gene frequencies of a, band 0 genes from abo blood group system and d and d genes from rhesus system are objectives of the present study. methods: the study was a cross sectional descriptive study. all the voluntary blood donors, 7361 people, attending to the hamadan, iran, blood bank during 1996 were studied. primary information from the sex of blood donors and their...

Background: Protein C (PC) deficiency has been reported in sickle cell disease (SCD) and postulated to contribute to the pathogenesis as well as clinical manifestations of SCD. However there is paucity of data on PC in Nigerian patients with SCD. Objectives: This study was aimed at evaluating the levels of Protein C (PC) antigen and activity in SCD subjects; the prevalent type of PC deficiency ...

Aim. To explore whether first-trimester levels of pregnancy-associated plasma protein-A (PAPPA) and serum free ß-human chorionic gonadotrophin (free ß-hCG) vary with maternal blood group and rhesus status and to determine their implications for Down syndrome. Methods. Blood samples were collected from all 539 singleton pregnancies undergoing first-trimester screening. Values of maternal serum P...

BACKGROUND Hemoglobinopathies are a group of inherited disorders of hemoglobin synthesis. It could be formed a fatal scenario in concern of lacking of actual information. Beside this, ABO and Rh blood grouping are also important matter in transfusion and forensic medicine and to reduce new born hemolytic disease (NHD). MATERIALS AND METHODS The spectrum and prevalence of various hemoglobinopa...

The frequencies of ABO and rhesus blood groups vary from one population to another. We studied blood group distribution in 120 Nepalese students; 34% were blood group A, 29% group B, 4% group AB and 32.5% group O. The frequency of Rh-negative blood was 3.33% and Rh-positive 96.66%.

abstract the association between abo blood groups and helicobacter pylori seroprevalence is still controversial. we aimed to study the association between abo/rh antigens and igg seropositivity in an iranian adult population for the first time. blood samples of 300 healthy young adults aging 18-30 years were collected for h. pylori antibody detection and abo/rhesus blood group antigen typing. 5...

This prospective study was designed to provide the frequencies of the haemoglobin genotypes, ABO and Rh blood groups and their effects on the haematocrit values among pregnant women in Port Harcourt. One hundred and eighty (180) pregnant women at their first clinic attendance and in their first pregnancy (parity - 0) participated in this study. The overall frequencies obtained for ABO and Rh bl...

Frequency of Rhesus and ABO blood groups was determined in 3012 mothers. The blood groups in order of frequency were B, O, A and AB. Only 6.2% mothers were rhesus negative. ABO haemolytie disease of the newborn (HDN) accounted for 15.7% and Rh-HDN for 12.7% of 306 neonate admitted with Jaundice. No significant difference was found in two groups when levels of serum bilirubin, exchange transfusi...
