Glucose-6-Phosphate Dehydrogenase Deficiency among Male Blood Donors inSana’a City, Yemen
Journal Title: Oman Medical Journal - Year 2012, Vol 27, Issue 1
Abstract
Objectives: To determine the prevalence of Glucose-6-phosphatedehydrogenase (G-6-PD) deficiency among Yemeni people fromdifferent regions of the country living in the capital city, Sana’a,giving an indication of its overall prevalence in Yemen. Methods: A cross-sectional study was conducted among Yemenimale blood donors attending the Department of Blood Bank atthe National Centre of the Public Health Laboratories in thecapital city, Sana’a, Yemen. Fluorescent spot method was used forscreening, spectrophotometeric estimation of G-6-PD activityand separation by electrophoresis was done to determine the G-6-PD phenotype. Results: Of the total 508 male blood donors recruited into thestudy, 36 were G-6-PD deficient, giving a likely G-6-PD deficiencyprevalence of 7.1%. None of these deficient donors had history ofanemia or jaundice. Thirty-five of these deficient cases (97.2%)showed severe G-6-PD deficiency class II (<10% of normalactivity), and their phenotyping presumptively revealed a G-6-PDMediterraneanvariant. Conclusion: The results showed a significant presence of G-6-PD deficiency with predominance of a severe G-6-PD deficiencytype in these blood donors in Sana’a City, which could representan important health problem through occurrence of hemolyticanemia under oxidative stress. A larger sample size is needed todetermine the overall prevalence of G-6-PD deficiency, and shouldbe extended to include DNA analysis to identify its variants in Yemen.
