[Glucose-6-phosphate dehydrogenase deficiency in Mali. Epidemiology and pathological aspects]
Abstract:
I,858 semi quantitative G6PD determinations were done in Mali (mostly in the Point G Hospital, in Bamako). 15.7% of the men and 4.5% of the women had a G6PD deficiency. The age did not affect the incidence of the disease. G6PD deficiency was more frequent among the Sonrais than among the other ethnic groups tested. It did not occur more frequently among subjects having the sickling trait of AC hemoglobinopathy but no G6PD was found among subjects having a major hemoglobinopathy (SS or SC). Severe hemolytic anemia was rather infrequent among adults subjects. Hemolysis was induced by drugs--such as dapsone or niridazole--but it was usually mild and time-limited.
Insights
Glucose-6-phosphate dehydrogenase (G6PD) deficiency affects 15.7% of men and 4.5% of women in Mali. This common genetic disorder is more prevalent in certain ethnic groups but is not linked to age or sickle cell trait.
Area of Science:
- Clinical Medicine
- Hematology
- Genetics
Background:
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common inherited red blood cell disorder.
- The prevalence and clinical manifestations of G6PD deficiency can vary significantly across different populations and geographic regions.
Purpose of the Study:
- To determine the prevalence of G6PD deficiency in a Malian population.
- To investigate the association of G6PD deficiency with demographic factors, ethnic groups, and hemoglobinopathies.
- To describe the clinical presentation of hemolysis induced by G6PD deficiency.
Main Methods:
- Semi-quantitative G6PD testing was performed on 1,858 individuals in Mali.
- Data were analyzed to assess G6PD deficiency prevalence by sex, age, ethnicity, and hemoglobin type.
- Clinical data on drug-induced hemolysis were collected and reviewed.
Main Results:
- G6PD deficiency was identified in 15.7% of men and 4.5% of women.
- Age did not significantly impact the incidence of G6PD deficiency.
- The Sonrai ethnic group exhibited a higher frequency of G6PD deficiency compared to other groups.
- No G6PD deficiency was observed in individuals with major hemoglobinopathies (SS or SC).
- Drug-induced hemolysis (e.g., by dapsone, niridazole) was generally mild and transient.
Conclusions:
- G6PD deficiency is prevalent in the studied Malian population, with notable sex and ethnic variations.
- The study highlights the importance of considering ethnic background in understanding G6PD deficiency distribution.
- While severe hemolytic anemia was infrequent, drug-induced hemolysis can occur but is typically manageable.
