Objetivo: realizar dosagens de biomarcadores de função renal não convencionais em pacientes com anemia falciforme e associar com os níveis séricos de vitamina D. Métodos: trata-se de um estudo observacional, analítico de corte transversal. Participaram do estudo 51 pacientes adultos com anemia falciforme, e o grupo controle foi composto por 17 adultos saudáveis doadores de sangue. Os níveis séricos de 25- hidroxi-vitamina D foram determinados por imunoensaio quimioluminecente de micropartículas (CMIA), e a função renal foi avaliada pelas dosagens de molécula-1 de lesão renal (KIM-1) e proteína-1 quimiotática de monócitos (MCP-1). Os resultados foram expressos como mediana (intervalo interquartil). Os testes t-Student de amostras independentes, análise de variância de Welch e teste não paramétrico de Kruskal-Wallis foram realizados para comparar as diferenças entre os grupos. Resultados: os pacientes apresentaram níveis séricos de vitamina D superiores ao grupo controle, além de uma maior prevalência de suficiência de vitamina D. Os níveis urinários de KIM-1 e MCP-1 estavam aumentados nos pacientes em relação ao grupo controle. Não houve relação entre baixos níveis séricos de vitamina D e a probabilidade de desenvolvimento de doença renal. Conclusões: este estudo fornece dados importantes sobre a prevalência da deficiência de vitamina D em pacientes com anemia falciforme e demonstra não haver relação entre baixos níveis de vitamina D e desenvolvimento de doença renal.
