The frequency of thiamine deficiency in chronic alcoholics and in patients at a long-term care facility / 대한내과학회지

ABSTRACT

BACKGROUND: As socioeconomic status has improved, malnutrition has become rare in Korea and generally it is no longer considered as a serious problem in medical practice. However, contrary to the above general belief we managed four patients with beriberi in 1999 and it became apparent that malnutrition might remain a problem in certain groups of patients. In this study, we assessed the nutritional state, especially with respect to thiamine deficiency, in chronic alcoholics and in patients residing at a long-term care facility (LTCF). METHODS: Fourteen chronic alcoholic patients and twenty patients being hospitalized in a long-term care facility were assigned as the study groups. The subjects' mean ages and standard deviations were 48.9+/-10.2 and 50.6+/-6.7, respectively. Medical records were reviewed to determine other aspects of their nutritional status and their dietary patterns. Ten peoples who visited the health promotion center at Inha University Hospital, for routine check-ups were allocated to the control group. Blood total thiamine levels were measured by high-performance liquid chromatography. RESULTS: Body mass indices were significantly lower in chronic alcoholics and in patients at the LTCF than in the control group (p=0.0065). Serum albumin levels were within the reference range in all three groups, but were significantly lower in patients at the LTCF than in the control group (p=0.0013). Moreover, no difference was detected between the alcoholic group and the control group in terms of thiamine levels. However, the mean thiamine level in patients at the LTCF was statistically lower than that of the control group and four (20%) patients in the LTCF group showed subnormal blood thiamine levels. The thiamine level tended to decrease with age in both alcoholics and patients at the LTCF. No correlation was found between thiamine level and the other variables examined, namely, hospital stay, body mass index, and serum albumin level. CONCLUSION: A considerable portion of patients in a long term care facility showed thiamine deficiency, however, no evidence of thiamine deficiency was found among alcoholics. This result suggests that thiamine deficiency in patients at long-term care facility may be more prevalent and that thiamine supplementation may be warranted, especially for those with other thiamine deficiency risk factors.
