Hemoglobin C disease, a global variant, was studied in 111 Moroccan cases over 12 years. Diagnosis involved various etiological groups, highlighting the need for genetic counseling and neonatal screening.

Area of Science:

  • Hematology
  • Biochemistry
  • Genetics

Background:

  • Hemoglobin C is a globally prevalent hemoglobin variant, with high incidence in West Africa and Southeast Asia.
  • This study focuses on cases of Hemoglobin C disease observed over a 12-year period at the Rabat Military Hospital Mohammed V.

Purpose of the Study:

  • To report and analyze cases of Hemoglobin C disease diagnosed over the past twelve years.
  • To characterize the epidemiological and clinical profiles of Hemoglobin C disease in the Moroccan population.

Main Methods:

  • A retrospective analysis of 111 Hemoglobin C disease cases.
  • Data collection included epidemiological, clinical, and biological exploration results via questionnaire.
  • Screening involved hemoglobin electrophoresis (acid and alkaline pH) and hematological tests.

Main Results:

  • The study identified a sex ratio of 1.22, with diagnosis ages ranging from 4 to 80 years (mean 38).
  • North-West Morocco showed a higher prevalence. Common reasons for testing included biological abnormalities, splenomegaly, and anemia.
  • Etiological groups identified were heterozygous A/C (75%), homozygous C/C (8%), double heterozygous S/C (9%), C/β+-thal (6%), and C/O-Arab (2%).

Conclusions:

  • Findings align with existing literature on Hemoglobin C disease.
  • Emphasizes the critical role of genetic counseling.
  • Recommends the implementation of a national systematic neonatal screening program.
