OBJECTIVE: This systematic review and meta-analysis aimed to synthesize the latest evidence on pentoxifylline effect on the contrast-induced nephropathy (CIN) and whether the quality evidence is sufficient to make a definite conclusion
MATERIALS AND METHODS: We performed a systematic literature search on topics that assesses pentoxifylline and CIN in coronary angiography/intervention up until 01 April 2021 using PubMed, Scopus, Embase, and hand-sampling. Primary outcome was CIN defined as ≥0.5 mg/dL or 25% rise in the SCr 48 h after procedure.
RESULTS: There were a total of 1142 subjects from 6 studies. There was no difference between pentoxifylline and control group in terms of serum creatinine at baseline (p=0.46) and after the procedure (p=0.33). The incidence of CIN was 51/571 (8.9%) in the pentoxifylline group and 61/571 (10.7%) in the control group. Pentoxifylline was not significantly associated with increase or decrease in the risk of CIN (RR 0.84 [0.59, 1.19], p=0.32; I2: 0%, p=0.89). Subgroup analysis for elective studies showed a non-significant result (RR 0.77 [0.47, 1.27], p=0.31; I2: 0%). Meta-regression analysis showed that the association between pentoxifylline and mortality was not affected by age (p=0.994), gender (reference: male, p=0.562), hypertension (p=0.336), diabetes (p=0.536), baseline serum creatinine (p=0.344), contrast used (p=0.431), and CIN incidence (p=0.521). GRADE Approach showed a low certainty of evidence for the effect estimate of pentoxifylline on CIN.
CONCLUSIONS: Our meta-analysis showed that pentoxifylline was not associated with the risk of CIN with low certainty of evidence. Hence, larger, multicentre, double-blind randomized controlled trials are required.Free PDF Download
