background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...

BACKGROUND Echocardiographic screening for detection of latent RHD has shown potential as a strategy to decrease the burden of disease. However, further research is needed to determine optimal implementation strategies. RHD results from a complex interplay between environment and host susceptibility. Family members share both and relatives of children with latent RHD may represent a high-risk g...

Ciljana zaščita z imunoglobulinom anti-D je program, ki na podlagi presejalnega testa omogoča neinvazivno določitev plodovega genotipa RHD iz periferne krvi RhD-negativne nosečnice. Pred uvedbo določanja predvidenega fenotipa RhD so vse nosečnice prejele zaščito v 28.–30. tednu nosečnosti. V Evropi 40 % RhD-negativnih nosečnic nosi RhD-negativen plod in zaščite ne potrebuje, saj med materjo plo...

BACKGROUND Immunoprophylaxis with IgG anti-D is a standard prevention of hemolytic disease of the fetus and newborn. Fetal Rhesus D (RhD) blood group genotyping from maternal plasma of RhD-negative pregnant women allows targeted prophylaxis with IgG anti-D in RhD-positive pregnancies only. We set up a reliable protocol for prenatal RHD genotyping. METHODS 153 pregnant Caucasian RhD-negative w...

Australia has articulated a commitment to eliminate rheumatic heart disease (RHD) by 2031. Business as usual will not achieve this goal. Diverse sectors need work together in implementing complementary strategies towards ambitious target. Rheumatic Heart Disease Australia’s ‘Champions4Change’ program is one important element that provides novel and vital approach. Champions4Change culturally sa...

BACKGROUND Rheumatic heart disease (RHD) and HIV are prevalent diseases in sub-Saharan Africa, but little is known about their potential interrelationships. The objective of this study was to assess the prevalence of protective natural autoantibodies among patients with RHD in Uganda, and to determine whether the levels of these autoantibodies are affected by HIV status. METHODS Participants ...

Background: RhD antigen system is the leading cause of hemolytic disease of the fetus and newborn (HDFN). Paternal molecular RhD zygosity test is valuable to decide on the use of anti-D immunoglobulin prophylaxis in Rh D-negative pregnant women. We aimed to investigate the paternal RhD zygosity by two molecular methods among blood donors in Kurdistan province, the west of Iran. We also compared...

The RhD protein which is the RHD gene product and a major component of the Rh blood group system carries the strongest blood group immunogen, the D-antigen. This antigen is absent in a significant minority of the human population (RhD-negatives) due to RHD deletion or alternation. The origin and persistence of this RhD polymorphism is an old evolutionary enigma. Before the advent of modern medi...

Recent molecular studies on the Rh blood group system have shown that the Rh locus of each haploid RhD-positive chromosome is composed of two structural genes: RHD and RHCE, whereas the locus is made of a single gene (RHCE) on each haploid RhD-negative chromosome. We analyzed the presence or absence of the RHD gene in 130 Japanese RhD-negative donors using the PCR method. The RhD-negative pheno...
