Hypercalcemia and renal function impairment associated with vitamin D toxicity: case report

Abstract: Nowadays vitamin D (25-OHD) deficiency is supposed to be a global epidemic condition. Expectedly, vitamin D measurement and intake exponentially increased in Brazil in this decade. Although the benefit of vitamin D to general health is still in debate, its indiscriminate use potentially may lead to enhance the incidence of vitamin D intoxication, which is considered a rare disorder. We report a case of a 70 year old diabetic male with chronic renal disease (blood creatinine of 1.6 mg/dL) who progressed suddenl… Show more

“…Seven paediatric cases of hypercalcaemia due to vitamin D intoxication were reported in association with a fish oil supplement, where the stated dose was roughly 4000 times less than the actual dose [31]; in one of these cases, an infant in whom the stated daily dose was 2000 IU day -1 was actually taking 6000 IU day -1 [30]. Toxicity associated with inaccurately manufactured and labelled vitamin D supplements is a globally reported problem [32,[34][35][36][37][38][39][40][41][42][43]. To our knowledge, such errant labelling has not been reported in conjunction with licensed formulations.…”

“…Atualmente, muitos brasileiros têm utilizado vitamina D3 como suplemento vitamínico para prevenção de diversas doenças crônicas, apesar da falta de dados científicos consistentes sobre o papel desta molécula na prevenção de doenças que não as do metabolismo mineral (17). Embora suplementos vitamínicos sejam muitas vezes usados com a in-tenção de alcançar benefícios para a saúde, efeitos cumulativos de seu uso generalizado, sem a correta indicação terapêutica, pode elevar os níveis séricos a concentrações acima do recomendado ocasionando efeitos adversos e intoxicação (37).…”

“…A intoxicação por vitamina D é muitas vezes de difícil detecção quando considerados apenas os sintomas clínicos que são não-específicos, entre eles: anorexia, vômitos, constipação, cefaléia, hipertensão, polidipsia e poliúria, dificultando inclusive a execução da farmacovigilância por parte do farmacêutico e outros profissionais de saúde (17,38). Assim, investigações bioquímicas são necessárias.…”
