Molecular studies on Yemeni sickle-cell-disease patients: Xmn I polymorphism
AbstractOur studies of the Saudi population have shown that in patients with mild presentation of sickle-cell disease [SCD] from Saudi Arabia's eastern region, the prevalence of polymorphic sites is high. However, the prevalence is very low in patients with severe SCD from the south-west of the country. We expanded these studies to a group of Yemeni patients with severe SCD, resident in Riyadh. We investigated a total of 60 chromosomes carrying the sickle-cell [Hb S] gene and 14 chromosomes carrying the Hb A gene. Amongst the Hb AA group, the prevalence was 42.9% and 57.1% for the presence [+] and absence [-] of Xmn I polymorphic sites. In the Hb SS individuals, the prevalence of Xmn I polymorphic sites was similar to the prevalence reported in the south-western region of Saudi Arabia

Bashawri, L.A.M.; Al Mulhim, A.A.; Ahmed, M.A.; Bahnassi, A.A. (2007)During the period January 2002- December 2004, we assessed 30 sickle- cell anaemia patients admitted to hospital in Al Khobar with vaso- occlusive crisis for levels of antithrombin [AT] III, protein C [PC] and protein S [PS]. We also did platelet aggregation studies. Steady state levels were assessed during follow- up and compared with 36 adult controls. Levels of PC, PS and AT III in the group were significantly higher than in those in vaso- occlusive crisis and those in steady state control [P < 0.001]. There was a statistically significant ...
Al Arrayed, Sheikha S.; Haites, Neva (1995)Genetic disorders of haemoglobin are prevalent in Bahrain. In a study of the hospital population covering 56 198 Bahrainis, we found that 2% of newborns have sickle-cell disease [SCD] and 18% have sickle-cell trait, while 24% are carriers of the [-thalassaemia gene. In a study of the presentation of SCD among Bahrainis it was found that the mild form of the disease predominates, but a wide clinical variability is apparent. It was also found that their haematological values are similar to those of patients from Eastern Province, Saudi Arabia, where ...
