Oral Statin Exposure Linked to Risk Reduction of Noninfectious Uveitis

This systematic review and meta-analysis found that the occurrence of noninfectious uveitis in patients with statin exposure may be less than that seen within the general population. This exposure also conferred a significant risk reduction for noninfectious uveitis, and this result remained in after risk of bias-stratified analysis and for most leave-out analyses.

Besides statins’ lipid-lowering properties, their potential effects on inflammatory ocular diseases have garnered clinical interest in statins as potential adjunctive therapies in autoimmune and inflammatory conditions. Recently statins have been investigated in ophthalmic conditions such as age-related macular degeneration, diabetic retinopathy and glaucoma.Because of this, a recent systematic review and meta-analysis published in Ophthalmology Science sought to synthesize the available literature on the association of oral statin use and noninfectious occurrence (incidence, prevalence or recurrence). Researchers based out of Toronto, Canada, hypothesized that oral statins may confer a protective effect against the condition’s onset. After identifying five studies, they found low-certainty evidence that supported a possible association between oral statin use and lower occurrence of noninfectious uveitis events. Nevertheless, the team noted that larger studies would help characterize the dose-response activity further.The meta-analysis consisted of five observational studies (n=864,465 participants). Over five studies, oral statin use was significantly associated with a lower occurrence of noninfectious uveitis (odds ratio: 0.76) compared to non-users. This result remained consistent in subgroup analysis excluding “high” risk of bias studies and, with the exception of one study, predominantly returned consistent results in the leave-one-out analysis.This one noted study contributed the majority of participants. Its exclusion yielded an attenuated and nonsignificant result.“These findings indicate that while the protective association persisted, the precision and statistical significance varied depending on which study was omitted, underscoring some instability in the results,” the study authors wrote. “We believe this reflects the limited number of available studies and the dominance of a single large dataset in an emerging research area, rather than contradictory evidence.”Publication bias was not significant. Four studies had “low” risk of bias, while one study had “high” risk of bias given a highly specific inclusion population. Overall, the researchers rated the evidence certainty of the evidence as “low,” due to the reliance on observational literature.Regarding study limitations, the study team did note that their analysis could not consider individual patient data due to data unavailability, which thereby introduces a risk of uncontrolled confounding or effect modifiers.“Our results should therefore be considered as hypothesis-generating,” they stated.Click here for the journal source.
