[Failure in self care and heart failure, thiamine deficiency in geriatric patients].

In two patients admitted to a geriatric ward cardiac failure was based on a thiamine deficiency (wet beri-beri). After supplementation with thiamine they recovered completely. The first patient had a insufficient diet of only canned food, whereas the second patient suffered from both alcoholism and insufficient nutrients. These geriatric patients suffered from a serious illness due to a combination of somatic, psychological, functional en social factors. Thiamine is a co-enzyme in many metabolic processes. A thiamine deficiency is defined as a serum concentration below 95 nmol/1. Other diseases associated with thiamine deficiency are the Wernicke-Korsakoff syndrome and peripheral polyneuropathy (dry beri-beri). Not only alcoholics but also elderly patients with malnutrition are at risk of thiamine deficiency and associated diseases. Do not hesitate to supplement thiamine in case of cardiac failure because of possible thiamine deficiency.
