BACKGROUND: Owing to high diarrhoea and protein malnutrition frequencies in pellagra, we hypothesised that pellagra patients would have higher electrolyte disturbances than non-pellagra alcoholics.
OBJECTIVE: To compare serum electrolytes of hospitalised alcoholics with or without pellagra.
DESIGN: Retrospective and descriptive case-control study.
SETTING: Internal Medicine wards at a University Hospital, Medical School of Uberaba, Brazil.
SUBJECTS: Medical records were reviewed to obtain relevant clinical details, main diagnosis and laboratory data, including serum electrolytes on hospital admission of pellagra patients (n=33) and a randomly chosen control group of alcoholics (n=37), matched in age, gender and socio-economic status. Anaemia was ascertained by haemoglobin <12.5 g/dl (men) and 1.5 g/dl (women), and hypoalbuminemia by serum albumin <3.3 g/dl.
RESULTS: Pellagra and controls showed similar age (39.4+/-13.1 vs 45.0+/-11.4 years) and a male predominance of gender (69.7 vs 78.4%), and similar associated diagnoses, including high blood pressure (21.2 vs 16.2%), peripheral neuropathy (12.1 vs 13. 5%), and pneumonia (9.1 vs 13.5%). Despite displaying similar serum sodium (136.6+/-6.1 vs 137.8+/-5.7 mEq/I), magnesium (1.72+/-0.74 vs 1.62+/-0.34 mg/dl), phosphorus (3.79+/-0.87 vs 3.87+/-0.78 mEq/1) than controls,in addition to higher hypoalbuminemia (76.2 vs 33%) and anaemia (60.6 vs 35.1%) frequencies.
CONCLUSIONS: Higher anaemia and hypoalbuminemia frequencies associated with lower serum potassium levels suggest increased protein malnutrition prevalence among pellagrins.
