A nutritional survey in the elderly: blood and urine vitamin levels.

In this survey of vitamin levels in 93 acute geriatric admissions to hospital, none had a completely normal nutritional profile. Twenty-two patients had over 50% of test abnormal and for all patients the average % of abnormal tests was 29%. The most common abnormalities were albumin, leucocyte vitamin C, vitamin E, carotene and nicotinic acid where over 50% of patients had abnormal results. Transferrin and vitamin A levels were abnormal in over 30% of patients while there was little evidence for riboflavin or thiamine malnutrition. It is postulated that an inadequate dietary intake, due to disease or to physical and mental deterioration was the most likely cause of these multiple nutritional abnormalities.

Plasma and urinary zinc in patients with malabsorption syndromes or hepatic cirrhosis.

Plasma and urinary zinc have been measured in 19 patients with malabsorption and 21 patients with hepatic cirrhosis. The results have been compared with those of 20 control subjects and 23 patients with a variety of other diseases. The diurnal variation in plasma zinc levels has been confirmed and is of such magnitude that this must be taken into account in comparing results in groups of subjects. Plasma zinc levels, both fasting and after a meal, are significantly lower in patients with cirrhosis (71 and 60 mug/100 ml) and malabsorption (76 and 64 mug/100 ml) than in controls (97 and 81 mug/100 ml). In the patients with cirrhosis or malabsorption similar correlations exist between plasma zinc and plasma albumin, suggesting that the low plasma zinc levels may be, at least in part, dependent on the plasma albumin level. Urinary zinc excretion is increased in cirrhosis, but not in malabsorption, indicating that increased urinary loss is unlikely to explain the low plasma levels.
