High alcohol consumption and the risk of renal damage: a systematic review and meta-analysis

BACKGROUND: The risk of renal damage in patients with high alcohol consumption is controversial. The objective of this meta-analysis was to evaluate the associations between high alcohol consumption and progression of kidney damage including chronic kidney disease (CKD), end-stage renal disease (ESRD) and proteinuria.

METHODS: A literature search was performed using MEDLINE, EMBASE and CochraneCochrane is a global independent network of health practitioners researchers patient advocates and o... Databases from inception through August 2014 to identify studies investigating the association between high alcohol consumption and CKD, ESRD or proteinuria. Studies that reported odds ratios, relative risks or hazard ratios comparing the risk of CKD, ESRD or proteinuria in patients consuming high amount of alcohol versus those who did not consume alcohol were included. Pooled risk ratios (RRs) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method.

RESULTS: Twenty studies with 292 431 patients were included in our analysis to assess the associations between high alcohol consumption and progression of kidney damage. The pooled RRs of CKD, proteinuria and ESRD in patients with high alcohol consumption were 0.83 (95% CI: 0.71-0.98), 0.85 (95% CI: 0.62-1.17) and 1.00 (95% CI: 0.55-1.82), respectively. Post hoc analysis assessing the sex-specific association between high alcohol consumption and CKD demonstrated pooled RRs of 0.72 (95% CI: 0.57-0.90) in males and 0.78 (95% CI: 0.58-1.03) in females.

CONCLUSIONS: Our study demonstrates an inverse association between high alcohol consumption and risk for developing CKD in males. There is no significant association between high alcohol consumption and the risk for developing proteinuria or ESRD.
