Abstract

We present the case of a 55-year-old female patient with alcohol-related liver damage who presented with hypercalcemia and hyperphosphatemia but also showed severe paradoxical reduction in serum 25-OH vitamin D levels. The serum levels of 1, 25-(OH) 2 vitamin D, parathyroid hormone, and renal function parameters were normal. Therefore, we examined the renal reabsorption of calcium and phosphate and found a mild increase in both. The serum levels of calcium and phosphate might be determined by 1, 25-(OH) 2 vitamin D-mediated excessive renal reabsorption of calcium and phosphate in alcoholics with 25-OH vitamin D deficiency but normal renal function.
