To the Editor: In their intriguing report relating hypokalemia to the development of renal cysts, Torres et al. (Feb. 8 issue)1 note with surprise a positive correlation of plasma renin activity with the extent of cystic involvement and demonstrate that higher plasma renin activity is the only factor other than a low plasma potassium concentration that is independently predictive of the presence of cysts in a multiple logistic regression analysis. The investigators suggest that uncommon sources, such as renal tubular epithelial cells or the adrenal gland, could contribute to renin levels, but it seems more likely that the renin is.
