Population

Children presenting with acute haemolytic crisis, New Children Hospital, Cairo University

Country

Egypt (Cairo)

Period

March-June 2016

5. Actual results

Results

76/143 (53.1%) G6PD deficiency; 36 (25.2%) chronic haemolytic anaemia; 31 (21.7%) undiagnosed acute haemolytic anaemia. Authors note that Egypt has no G6PD screening programme.

Not applicable

Authors' conclusion

Haemolytic anaemia is a very common ED presentation; G6PD deficiency is the most common cause (53.1%).

  • Prospective
  • Paediatric Egyptian setting

9. Assessment of the statistical interpretation

Proportions among haemolysis cases, not population incidence.

10. Relevance to the specific claim

Shows that G6PD-related haemolysis is a leading cause of acute haemolytic crises in Egyptian children (safety relevance of C-LEG-03).

11. Independent contrary findings

None.

12. Transferability to Germany and Europe

Egypt-specific.

13. Overall methodological judgement

Supports the clinical importance of G6PD deficiency for Egyptian children.
