Efficacy and Safety of Lotilaner Ophthalmic Solution (0.25%) for the Treatment of Demodex Blepharitis: A GRADE Assessed Systematic Review and Meta-Analysis of Observational & Experimental Studies.

PURPOSE: Several treatments have been in use for Demodex blepharitis, before the discovery of lotilaner, like tea tree oil and antibiotics; however, they either have irritable effects or systemic adverse effects, respectively. Lotilaner, a novel ectoparasiticide, has been proposed as a treatment for patients grappling with Demodex blepharitis. This review aims to assess the safety and efficacy of lotilaner in the treatment of Demodex blepharitis. DESIGN: Systematic review and meta-analysis. METHODS: An extensive search was conducted on PubMed, Cochrane Library, Scopus, and Google Scholar to find relevant literature till July 31, 2023 following the PRISMA guidelines. A total of 143 articles were retrieved by database searching, out of which 6 studies met the inclusion criteria and were included in the review. Four randomized controlled trials were included in the meta-analysis of mite eradication incidence. The review is registered with PROSPERO: CRD42023459997. RESULTS: Lotilaner is effective in eradicating Demodex mites in individuals suffering from Demodex blepharitis according to RR for the intervention versus the control group of 3.55 (95% confidence interval [CI]: 2.87-4.40, P < .00001, I2 = 0%). The meta-analysis of clinically meaningful collarette score revealed the summary RR for the intervention versus the control group was 3.15 (95% CI: 2.56-3.89, P < 0.00001, I2 = 27%). In conclusion, the results of the included studies were comparable and consistent. CONCLUSIONS: Our results indicated that lotilaner is an effective, well-tolerated, and promising drug in treating patients with Demodex blepharitis. Lotilaner administration and cost-effectiveness should now be contemplated for the study population as these constituents have a vital impact on its treatment success.

Evaluation of non-invasive diagnostic tools for diarrhea: a systematic review of point-of-care tests and biomarkers.

Background: Diarrhea is a prevalent condition affecting millions worldwide. However, current standard diagnostic methods have many drawbacks. This review examines various non-invasive point-of-care (POC) tests and biomarkers aiding rapid diagnosis of diarrhea from different causes. Methods: PubMed, PubMed Central, ScienceDirect, Cochrane Library, and Google Scholar were searched from 2013 to present for relevant literature. Two reviewers independently assessed included studies' quality using the Critical Appraisal Skills Programme (CASP) checklist. Results: The search yielded 1453 studies, of which 39 were included after screening and applying eligibility criteria. Polymerase chain reaction (PCR) was the POC test in 25 studies, providing consistent sensitivity and specificity. For biomarkers, C-reactive protein (CRP), fecal calprotectin, and procalcitonin offered high sensitivity and specificity for conditions like acute pediatric diarrhea, microscopic colitis, and inflammatory diarrhea, respectively. Conclusion: PCR proved the ideal POC test for rapid diarrhea diagnosis, while the procalcitonin biomarker helps differentiate inflammatory from non-inflammatory diarrhea. Other reviewed tools also demonstrated promising diagnostic performance, though improvements in sensitivity, specificity, and usability are still needed.
