Background: It is now well-known that some antimalarials such as primaquine may induce severe hemolytic anemia
in people with G-6-PD deficiency. Antimalarial drug prescriptions must, therefore take into account the patient’s G-6-PD status in malaria endemic areas such as Burkina Faso, where the prevalence of this genetic abnormality is relatively high. Although great clinical heterogeneity is observed depending on the molecular nature of the deficiency and the residual enzyme activity in the red blood cell, there is very poor data on the prevalence of G-6-PD deficiency and the distribution of involved genetic variants in Burkina Faso. In this systematic review, we present a synthesis of the various studies carried out on the G-6-PD deficiency in Burkina Faso in order to determine its prevalence, probable distribution of the genetic variants involved and their clinical implications for a national systematic screening policy among the groups most vulnerable to malaria.
Methods: A systematic review was carried out to analyze available published data on the prevalence, phenotypes and
mutations responsible for G-6-PD deficiency in Burkina Faso. The key words used were “G-6-PD deficiency AND Burkina Faso” or “Déficit en G-6-PD AND Burkina Faso” in French. To identify the relevant articles, two independent reviewers reviewed the titles, abstracts and the full text of the selected papers.
Results: An average prevalence of 16.6% (183/1100; CI 95%: 0.145–0.190) and 6.5% (69/1066; CI 95%: 0.051–0.081) of G6-PD deficiency was found respectively in men and women in this systematic review. Although the predominance (99.8% of G-6-PD deficient cases) of 202A/376G G-6-PD A- variant, the Santamaria and Betica Selma variants were identified in Burkina Faso. Independently of the method used, the enzymatic deficiency was significantly higher in males (2.5–20.5%) compared to females (3.3–12.3%).
Conclusion: This systematic review suggests that despite the ubiquity of the 202A/376G G-6-PD A- variant in Burkina
Faso, it will be necessary to consider the Santamaria and Betica Selma variants although their frequencies remain to be specified. A systematic screening of the G-6-PD deficiency is also needed to prevent the occurrence of iatrogenic
hemolytic accidents.
