Abstract
OBJECTIVE: To review the literature about the prevalence of vitamin D deficiency and its consequences in children and adolescents with sickle-cell disease. DATA SOURCES: The literature survey was performed through the bibliographic databases Medline; U.S. National Library of Medicine and National Institutes of Health (PubMed); Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), and the Cochrane Library. The keywords were selected using Medical Heading Terms (MeSH): "Vitamin D" OR "Vitamin D deficiency" AND "Anemia, Sickle Cell" AND "Child" AND "Adolescent". The search was limited to articles in English, Spanish and Portuguese, published until April 2014. DATA SYNTHESIS: Eleven articles were selected among the 18 found. In 6 of the 11 studies, serum levels of vitamin D in children and/or adolescents with sickle-cell anemia were low. The prevalence of vitamin D deficiency in patients with sickle-cell anemia exceeded that of the comparison group. The low intake of vitamin D, seasonality, exposure to sun, increased metabolism associated with the hemoglobinopathy, and age increase were factors associated with the deficiency. There was an association between a significant vitamin D deficiency and bone weakness and painful crises. There was a positive correlation between increased levels of vitamin D by supplementation and functional, physical capacity.Entities:

Summary of selected articles for the review: sickle cell disease and vitamin D.
| Reference | Level of evidence | Sample ( | Conclusion |
|---|---|---|---|
| Osunkwo et al. | 2 | 46 | The results suggest the potential benefit of vitamin D supplementation in the reduction of the number of days with pain in sickle cell disease. |
| Shams et al. | 2 | 58 | Vitamin D administration was associated with lower postoperative analgesia requirement and postoperative complications. |
| Jackson et al. | 6 | 139 | Low levels of vitamin D were associated with lung function, but were not associated with painful crises and acute chest syndrome. |
| Osunkwo et al. | 6 | 53 | Patients with sickle-cell disease have a tendency to vitamin D deficiency, and research suggests an association between vitamin D deficiency and bone fragility. |
| Garrido et al. | 6 | 78 | Vitamin D deficiency was prevalent in children with sickle-cell disease in Madrid. |
| Van der Dijs et al. | 6 | 18 | The vitamin D levels in patients with sickle-cell anemia in Curacao are appropriate. |
| Chapelon, et al. | 6 | 53 | A slight decrease in bone mineral density, unrelated to vitamin D deficiency, was found in children with sickle-cell disease, beginning at puberty and being more marked among females. |
| Buison et al. | 6 | 65 | Low serum levels of vitamin D had a high prevalence in children with sickle-cell disease and were associated with seasonal variations and diet. |
| Rovner et al. | 6 | 150 | The risk of individuals with sickle-cell disease to have vitamin D deficiency was 5.3 times higher than that of healthy subjects. |
| Lal et al. | 6 | 25 | Children with severe manifestations of sickle-cell disease have low bone density, as well as a diet poor in calcium and vitamin D. Vitamin D deficiency was higher in patients whose weight and/or height were below average. |
| Ozen et al. | 6 | 50 | The results suggest the potential benefit of vitamin D supplementation on reducing the number of days with pain in sickle-cell disease |

| Referência | Nível de evidência | Amostra (n) | Conclusão |
|---|---|---|---|
| Osunkwo et al., 2012 | 2 | 46 | Os resultados sugerem benefício potencial da suplementação da vitamina D na redução do número de dias com dor na doença falciforme |
| Shams et al., 2014 | 2 | 58 | A administração de vitamina D esteve associada com menores necessidades de analgesia pós‐ operatória e complicações pós‐operatórias |
| Jackson et al., 2012 | 6 | 139 | Os baixos níveis de vitamina D estavam associados à função pulmonar, mas não tiveram associação com crises álgicas e síndrome torácica aguda |
| Osunkwo et al., 2011 | 6 | 53 | Pacientes com doença falciforme têm uma tendência à deficiência de vitamina D e a pesquisa sugere ligação entre a deficiência de vitamina D e fragilidade óssea |
| Garrido et al., 2012 | 6 | 78 | Deficiência de Vitamina D foi prevalente em crianças com doença falciforme de Madrid |
| Van der Dijs et al., 1997 | 6 | 18 | O nível de vitamina D em pacientes com anemia falciforme de Curaçao é adequado |
| Chapelon, et al., 2009 | 6 | 53 | Uma leve diminuição da densidade mineral óssea, sem relação com hipovitaminose D, foi encontrada em crianças com anemia falciforme. Iniciaou‐se na puberdade e foi mais marcante entre mulheres |
| Buison et al., 2004 | 6 | 65 | Baixos níveis séricos de vitamina D tiveram alta prevalência em crianças com anemia falciforme e estavam associados às variações sazonais e dieta |

| Lal et al., 2006 | 6 | 25 | Crianças com manifestações graves de doença falciforme apresentam baixa densidade óssea, bem com dieta pobre em cálcio e vitamina D. A deficiência de vitamina D foi maior em pacientes cujos pesos e/ou altura estavam abaixo da média |
