Biologic Therapy improves Renal Function in Psoriasis: Study

This study is aimed at evaluating renal function in patients with moderate-to-severe chronic plaque psoriasis treated with biological therapy. A group of researchers analyzed 92 patients, correlating PASI and serum creatinine levels at baseline, after 6 months and after 1 year of continuous treatment with biological therapy. Data were analyzed using paired t-test and the linear mixed model for PASI and serum creatinine levels correlation, whereas the analysis of variances (ANOVA) was used for creatinine levels assessment between the baseline, the 6-months and, 1-year later evaluation.

The results of the study are:

The researchers observed a significant mean decrease in comparing serum creatinine levels after 1 year of biological therapy (p < 0.001). Interestingly, PASI reduction is correlated with creatinine decrease, and the renal function improvement is greater when complete psoriasis remission is attained.

Thus, the researchers concluded that their data suggest that a drop in systemic inflammation, secondary to biological therapy administration, might improve renal function. Future research is needed to confirm and expand our findings.
