vitamin d intoxication with hypercalcemia due to overuse of supplement
we describe a patient with hypercalcemia associated with the injection of high doses vitamin d as supplement for a period of six months. a 76-year-old woman had been taking an intramuscular injection of vitamin d 300,000 iu every ten days for six months. she was hospitalized with symptoms of hypercalcemia: chronic constipation, unstable gait, a chronic generalized musculoskeletal pain and incre...
متن کاملSevere hypercalcemia following vitamin d supplementation in a patient with multiple sclerosis: a note of caution.
OBJECTIVE To describe a patient with multiple sclerosis (MS) who developed severe hypercalcemia, attributed to the additive effect of 5500 IU of cholecalciferol and 2020 mg of calcium daily. DESIGN Case report. SETTING University hospital. PATIENT A 58-year-old woman with MS and osteoporosis presenting with acute-onset tremors and confusion.

متن کاملEffects of vitamin D-induced chronic hypercalcemia on rat renal cortical plasma membranes and mitochondria.
Increases in intracellular and mitochondrial calcium content that accompany ischemic and toxic acute renal failure have been suggested to mediate renal tubular cell injury and dysfunction, but the mechanism(s) are unknown. We studied the effects of in vivo vitamin D-induced chronic hypercalcemia on rat renal cortical brush-border and basolateral membranes and mitochondria. In the brush-border m...
متن کاملHypocalcemic Cardiomyopathy and Pseudohypoparathyroidism Due to Severe Vitamin D Deficiency.
Hypocalcemic cardiomyopathy is a rare entity. We describe a patient with severe heart failure, decreased ejection fraction and global hypokinesia documented on echocardiogram, associated with severe hypocalcemia, very low vitamin D status, increased QT intervals, increased BNP (serum brain natriuretic peptide) levels and CPK (creatine phosphokinase) levels. All these defects reversed on treatme...
متن کاملHypercalcemia and elevated concentration of vitamin D: A case report too easy to be true.
BACKGROUND Endogenous (heterophile, human anti-animal …) antibodies are a known cause of interference in immunoassays. CASE REPORT A patient with hypercalcemia and low PTH levels was investigated. The serum 25OH vitamin D (25OHD) concentration was above the analytical range of the automated analyser (>150ng/mL) but serum dilutions were not linear. A myeloma-related monoclonal peak of immunogl...
