Determine renal function and factors that influence reduction in renal function among Minahasanese with chronic gout arthritis and tophi.
This is a descriptive cross-sectional study where study subjects are recruited using multi-stage sampling. The data are descriptively processed using T-test, Pearson correlates, and multiple regression analysis.
The proportion of mild, moderate, and severe reductions in renal function in Minahasanese with chronic gout arthritis and tophi were as follows: 25 patients (69.7%), 7 patients (19.5%), and 5 patients (11%). According to Pearson correlation, only urinary uric acid excretion (r=0.626, p=0.000). The same findings were found using multiple regression, only urinary uric acid excretion is significant (p=0.001).
Most Minahasanese with chronic gout arthritis and tophi suffer from a mild reduction in renal function associated with the amount of uric acid excreted in the urine, but not associated with age, serum uric acid level, duration of gout arthritis, or tophi. Correlation with duration of gout arthritis, or tophi. Correlation with hypertension and use of NSAID are not evident in this study.
