Obesity, a well-known phenomenon in Western society, is frequently associated with cardiovascular and endocrine disease. Strokes, myocardial infarction, diabetes and hyperlipidemia are classical reasons for the high mortality and morbidity of overweight people. For this reason, intensive weight-reduction programs have been proposed: low-calorie diets, total starvation, drugs and even surgery. Total starvation and some low-calorie diets are, however, also associated with sudden death, most probably of cardiac origin. Experimental data from our laboratory show that total starvation is accompanied by a severe depletion of magnesium in myocardial tissue. Protein-sparing modified low-calorie diets, however, can protect against this mineral loss even if magnesium supplementation alone cannot obtain this goal. Applying these principles in overweight man show weight reduction without mineral loss or cardiac disturbance. Surgery with 'ileal bypass' procedures gives rise to severe hypomagnesemia and hypocalcemia with tetany and spasmophilia. New procedures, derived from experimental surgery, are 'gastric bypass' and 'gastroplasty'. These methods, only applied in very obese patients (body mass index greater than 40, normal 23-27) show no change in mineral concentrations of calcium and magnesium and no clinical symptoms suggestive for mineral loss. A good, controlled weight-reduction program under strict medical surveillance can, in this way, offer new perspectives in the treatment of one of our most frequent 'culture-induced' diseases.

We report a case of severe citrate toxicity during volunteer donor apheresis platelet collection. The donor was a 40-year-old female, first-time apheresis platelet donor. Past medical history was remarkable for hypertension, hyperlipidemia, and depression. Reported medications included bumetanide, pravastatin, and paroxetine. Thirty minutes from the start of the procedure, the donor noted tingling around the mouth, hands, and feet. She then very rapidly developed acute onset of severe facial and extremity tetany. Empirical treatment with intravenous calcium gluconate was initiated, and muscle contractions slowly subsided over approximately 10 to 15 minutes. The events are consistent with a severe reaction to calcium chelation by sodium citrate anticoagulant resulting in symptomatic systemic hypocalcemia. Upon additional retrospective analysis, it was noted that bumetanide is a loop diuretic that may cause significant hypocalcemia. We conclude that careful screening for medications and underlying conditions predisposing to hypocalcemia is recommended to help prevent severe reactions due to citrate toxicity. Laboratory measurement of pre-procedure serum calcium levels in selected donors may identify cases requiring heightened vigilance. The case also illustrates the importance of maintaining preparedness for managing rare but serious reactions in volunteer apheresis blood donors.
