BACKGROUND
The occurrence of deteriorating renal function test results along with the attempts at diuresis of anasarca has been described but not named, and no solution other than the standard treatment of related medical conditions such as congestive heart failure (CHF) and reducing or stopping diuretics has been offered. Phosphodiesterase type 5 inhibitors (PD5I) are known to reduce pulmonary hypertension (PH). The PD5Is sildenafil and, just recently, tadalafil, have FDA indications in primary pulmonary hypertension (PPH).
METHODS
In this observational study of CorPRADA patients treated with PD5I, 12 out of 19 cases met criteria for inclusion in statistical analysis. Medication reductions/discontinuations generally were made. Pre- and post-treatment data were analyzed using matched pairs.
RESULTS
There were significant improvements in edema, glomerular filtration rate (GFR), weight, and loop diuretic dosage required, while strong trends were seen in urine output per day and urine output per unit loop diuretic per day.
CONCLUSIONS
The identification of CorPRADA and the use of standard treatments for PH plus PD5I medication show promise in achieving successful diuresis of anasarca while stabilizing or improving renal function simultaneously.
