1. Thiamin, riboflavin and pyridoxine status of 'low-income-group' mothers and their newborn infants was assessed by analysing paired samples of maternal and umbilical cord blood for erythrocyte transketolase (EC 2.2.1.1) (ETK), erythrocyte glutathione reductase (EC 1.6.4.2) (EGR), and erythrocyte aspartate aminotransferase (EC 2.6.1.1) (EAA) activities. 2. The vitamin status of the infants was better than that of the mothers. 3. Most of the mothers and some of the infants had biochemical evidence of thiamin and riboflavin deficiency. 4. The pregnant women had a higher EAA activity and also higher stimulation with pyridoxal-5-phosphate than the non-pregnant women of the same community. 5. There was a significant correlation between maternal and umbilical blood samples for ETK and EGR activities, but not for EAA activity or any of the coenzyme stimulation tests.

Vitamin B1, B2 and B6 status were determined in 90 male heroin addicts admitted to Pramongkutklao Army Hospital. Their age (Mean +/- S.D.) was 25.5 +/- 7.8 years. Their activation coefficients of the enzyme transketolase, glutathione oxidoreductase and aspartate aminotransferase (ETK AC, EGR AC and EAST AC respectively) were significantly increased for addicts who were on drugs for a long time which indicated a biochemical deficiency. In addition, 26 follow-up cases treated with methadone for a period of one and two weeks were compared before and after treatment and it was found that ETK AC, EGR AC, and EAST AC were significantly decreased. This means that improvement in the vitamin B1, B2 and B6 status was obtained during admission.

The aim of this study was to assess the prevalence of thiamin, riboflavin and pyridoxine deficiencies at admission to an acute hospital. One hundred and twenty adult patients were selected at random from those admitted via the Accident and Emergency department over 3 days. Comparisons were made with a group of 80 healthy blood donors sequentially attending a local transfusion centre. The alcohol intake of 500 patients admitted sequentially via the same Accident and Emergency department was also assessed. Erythrocyte transketolase (ETK), glutathione reductase (EGR) and aspartate aminotransferase (EAA) coenzyme activation assays were used to determine thiamin, riboflavin and pyridoxine deficiencies. The prevalences of deficiency states in the inpatient group were 21, 2.7 and 32% for thiamin, riboflavin and pyridoxine deficiencies respectively with 49.2% being deficient in one or more vitamin. The mean alcohol intake in the group of patients in whom this was assessed was 9.7 units per week compared with 10 units per week amongst blood donors.
