[Secondary hyperparathyroidism of chronic hemodialysis].
Secondary hyperparathyroidism is defined as autonomic secretion of parathormon (PTH) whose 1-84 fraction level is up to 60 ng/l. The aim of this study was to determine incidence of secondary hyperparathyroidism on patients undergoing hemodialysis in Le Dantec Hospital of Dakar, and describe its diagnostic and therapeutical aspects. Between 22 patients followed in chronically hemodialysis, 11 patients had effective blood test of parathormon. Seven of them had high level of PTH and the other had normal rate. They were 5 men and 7 women with a mean age of 56 years. The mean duration undergoing hemodialysis was 42 months. Clinical signs were rare and non specific, dominated bony pains and anemia. Ectopic calcifications had been found in 3 cases. Hypocalcemia was present in 5 cases and high level of phosphoremia in all cases. The D3 vitamin was at a normal rate in all cases up to 10 ng/ml. Calcium supplementation with 1.5 to 2.5 g/day was effective associated with rich calcium dietary. This level of calcium supplementation appeared too low even though it must be closely estimated because of the possibility of improving ectopic calcifications. At the opposite, D3 vitamin supplementation seems to be unuseful under tropical areas.
