Plain-language summary
Suboptimal vitamin D status is well reported in sickle cell disease (SCD) patients and associated with a negative impact on health-related quality of life (HRQL). The investigators enrolled 42 SCD patients and 42 healthy controls, subjects within each group received monthly oral vitamin D3 dose according to the baseline status of vitamin D as follows: sufficient: 100,000 IU, insufficient: 150,000 IU, and deficient: 200,000 IU. The investigators assessed safety and efficacy on normalization of vitamin D level, bone mineral density (BMD), hand grip strength (HGS), and HRQL.
