The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in December 2019 in Wuhan city, Hubei province, China. This is the third and largest coronavirus outbreak since the new millennium after SARS in 2002 and Middle East respiratory syndrome (MERS) in 2012. Over 3 million people have been infected and the COVID-19 has caused more than 217 000 deaths. A concern exists regarding the vulnerability of patients who have been treated with immunosuppressive drugs prior or during this pandemic. Would they be more susceptible to infection by the SARS-CoV-2 and how would their clinical course be altered by their immunosuppressed state? This is a question the wider medical fraternity—including ophthalmologists, rheumatologists, gastroenterologist and transplant physicians among others—must answer. The evidence from the SARS and MERS outbreak offer some degree of confidence that immunosuppression is largely safe in the current COVID-19 pandemic. Preliminary clinical experiences based on case reports, small series and observational studies show the morbidity and mortality rates in immunosuppressed patients may not differ largely from the general population. Overwhelmingly, current best practice guidelines worldwide recommended the continuation of immunosuppression treatment in patients who require them except for perhaps high-dose corticosteroid therapy and in patients with associated risk factors for severe COVID-19 disease.
Topic: Herpes simplex virus (HSV) and varicella zoster virus (VZV) are the most common ocular pathogens associated with infectious anterior uveitis. Currently, there are a number of antiviral agents administered to treat viral anterior uveitis (VAU). However, there is no consensus or guidelines about the most appropriate approach leading for the best treatment outcomes with fewer ocular complications.Clinical Relevance: To perform a systematic review and meta-analysis of the efficacy of different antiviral therapies in the management of anterior uveitis secondary to HSV and VZV.Methods: We searched PubMed, Web of Science, CINAHL, OVID, and Embase up to January 2020. Randomized trials, non-randomized intervention studies, controlled before and after studies and observational studies assessing the effect of oral and or topical treatments for VAU were considered. Data extraction and analysis with evaluation of the risk of bias in the included trials were performed.Results: Oral acyclovir demonstrated a statistically significant good treatment outcome in the management of VZV anterior uveitis (vs. placebo) (OR 0.26, 95% CI 0.11–0.59), but did not have similar effect in HSV anterior uveitis (OR 0.47, 95% CI 0.15–1.50). In the treatment of VZV anterior uveitis, there was significant superiority of oral acyclovir−7 day course—over topical acyclovir (OR 4.17, 95% CI 1.28–13.52). Whereas, there was no significant superiority of one of the following treatment regimens over the others: topical acyclovir over topical corticosteroids (OR 1.86, 95% CI 0.67–5.17), and oral acyclovir−7 day course—over oral acyclovir−14 day course—(OR 0.21, 95% CI 0.01–4.50) or oral valaciclovir (OR 1.40, 95% CI 0.48–4.07).Conclusion: Treatment of HSV and VZV anterior uveitis is currently based on individual experiences and limited literature, largely due to weak clinical trial evidence in this regard. Our results highlight the existence of a substantial gap in our evidence base. This finding might contribute to future research studies to ascertain the role of different antiviral therapies in the treatment of VAU.Systematic Review Registration: PROSPERO registration number: CRD420202 00404.
Purpose: To report a case of bisphosphonate-induced bilateral anterior uveitis and choroidal effusions with secondary angle closure in a 64-year-old female patient.Methods: Observational case report.Results: A 64-year-old woman with history of scleroderma and antiphospholipid syndrome, presented with bilateral painless blurring of vision after commencement of alendronate. Clinical examination revealed bilateral anterior uveitis and choroidal effusions with resultant secondary angle closure in the left eye. Ultrasound biomicroscopy showed bilateral anteriorly rotated ciliary bodies. There was also a −2D myopic shift in the left eye. On drug cessation, complete resolution was seen within 2 weeks.
Conclusion:In the absence of other plausible etiologies and with recent commencement of a new drug, we postulate that the anterior uveitis and choroidal effusions are likely due to alendronate. This is further supported by complete resolution of the inflammation and effusions once alendronate was withheld.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
