The usefulness of serum albumin and urinary creatinine as biochemical indices for monitoring the nutritional status of Nigerians with pulmonary tuberculosis

The objective is to evaluate the relative roles of urinary creatinine and serum albumin as biochemical markers for monitoring the nutritional status of pulmonary tuberculosis patients during treatment. Thirty-one newly diagnosed pulmonary tuberculosis patients were placed on six months short course regimen. Their weight, body mass index, serum albumin and 24-hour urinary creatinine excretion were determined before treatment, at the end of the 1st, 2nd, 4th and 6th month of treatment. Subjecting the mean values of the weight, BMI and Urinary Creatinine excretion and serum albumin to Friedman test showed significant changes for all the four indices. Further analysis with paired student t-test of the pre-treatment values with end of 6th month values confirmed significant changes in the mean values of weight, BMI and serum albumin. Of these three indices serum albumin with chi-square value of 103.515 demonstrated the most significant changes, while the minimal change observed in urinary creatinine excretion could not be confirmed with paired t-test. We recommend serum albumin (as a more sensitive index) for monitoring the nutrition of patient with pulmonary tuberculosis.
