Thiamine deficiency in the chronic alcoholic would appear to have a triple origin: inadequate intake, absorption and utilisation. Its consequences are well known: peripheral neuropathy, WERNICKE and KORSAKOFF type encephalopathies and cardiac problems (with asystole at the extreme). The active principle of thiamine, TPP or cocarboxylase, is involved as a coenzyme of pyruvate decarboxylase and of alphaketoglutarate decarboxylase in the ocidative decarboxylation reactions of the Krebs cycle. TPP is involved as a coenzyme of transketolase in the transketolisation reactions of the pentose pathway. The stimation of transketolase demonstrates a deficiency in thiamine. Fourteen patients suffering from surgical ENT malignancies were involved in the present study. Seven patients received vitamin B therapy before and after the operation. The results showed a significant decrease in thiamine deficiency. Seven were used as controls and did not receive vitamin B therapy. Transketolase estimations showed and increase in the deficiency. Thiamine deficiency exists in the chronic alcoholic and may be corrected by the administration of B vitamins.
