title: Prophylaxis of folate deficiency in acutely ill patients: results of a randomized clinical trial.
abstract: A trial was carried out of prophylaxis of folate deficiency in 105 acutely ill patients immediately following admission to an ICU with evaluation of folate status. These patients were fed either orally or by enteral or parenteral nutrition. Three groups were established regardless of the type of nutrition: - Group 1 received 5 mg/day parenteral folinic acid; - Group 2 received 50 mg/week parenteral folinic acid; - Group 3 received no parenteral folinic acid. Before treatment, 19% of the patients presented very low serum folate levels (less than 2.7 ng/ml). Two of them developed acute folate deficiency with severe hematological disturbances quite reversed with folinic acid. Folate levels were inversely correlated with the severity of the clinical status and were lower in septic and feverish patients. The effect of folinic acid administration was assessed after seven days of treatment: daily administration of 5 mg folinic acid appeared to be the best regimen with normalization of serum folate levels in all cases; results appeared to be better than with 50 mg once weekly. Oral and enteral administration of folate supplies considered to be physiological (300 micrograms/day folic acid) did not appear to be sufficient to normalize in all cases blood folate levels in these acutely ill patients.
