Pubertal patterns in children with sickle cell anemia: A case–control study in Cameroon

Abstract

BackgroundPuberty may be impaired in children with sickle cell anemia (SCA). Therefore, we aimed to explore the clinical and hormonal features of puberty in Cameroonian children. MethodsIn a case–control study, we included 64 children aged 8–18 years with SCA matched to healthy controls. We assessed height, weight, body mass index, body composition, and Tanner stages. Hormonal measurements included anti-mullerian hormone, follicle-stimulating hormone, luteinizing hormone, and sex hormones (estrogens/testosterone). We used the Mann–Whitney Wilcoxon test to compare the median values between cases and controls. We looked for associations between the severity criteria of SCA and delayed puberty through multivariate analysis. ResultsDelayed puberty was reported in 27.3% of girls and 10% of boys with SCA. The median age of menarche was delayed by 2 years compared to controls. SCA patients had a low lean body mass compared to controls (p = 0.03). Anti-mullerian hormone levels were significantly higher in boys with SCA than those of controls (45.9 ng/mL vs. 17.65 ng/mL; p = 0.018). A history of severe infection, acute chest syndrome, and low hemoglobin level was associated with delayed sexual maturation in children with SCA. ConclusionOur study revealed delayed puberty in children with SCA. Moreover, puberty is affected by the severity of the disease. This highlights the importance of regular monitoring of puberty during the follow-up of these children.
