Back ground: Leptospirosis is one of the common zoonotic diseases, endemic among farmers. Globally, awareness of risk factors is reported to be very low. This study aims to quantitatively analyze the knowledge and attitude related to leptospirosis in Madurai district and to identify misconceptions that result in poor practice.Material & methods: A cross-sectional survey on rural and urban population using a structured, validated questionnaire to assess Knowledge, Attitude and Practice on Leptospirosis.Results: 902 participants from rural and 1074 participants from urban population were enrolled. More than 98% knew seasonal fever to be common during rainy season, of them only 2.8% and 3.6% from rural and urban population mentioned microbes as a cause.Conclusion: Vulnerable populations were found to be less knowledgeable on risk factors and they had poor practice. Education had significant impact on knowledge and attitude of urban population; however, their practice did not improve with education. [ABSTRACT FROM AUTHOR]

Background: The antimetabolites methotrexate (MTX) and mycophenolate mofetil (MMF) are commonly used as initial corticosteroid-sparing treatment for uveitis. There is little data examining risk factors for failing both MTX and MMF. The objective of this study is to determine risk factors for failing both MTX and MMF in patients with non-infectious uveitis. Main body: This is a sub-analysis of the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial, which was an international, multicenter, block-randomized, observer-masked, comparative effectiveness trial comparing MTX and MMF as initial treatments for non-infectious uveitis. This study was undertaken at multiple referral centers in India, the United States, Australia, Saudi Arabia and Mexico between 2013 and 2017. A total of 137 patients who completed all 12 months of follow-up from the FAST trial, were included in this study. The primary outcome was failing both antimetabolites over the 12 months of the trial. Potential predictors included: age, sex, bilateral involvement, anatomic location of the uveitis, presence of cystoid macular edema (CME) and retinal vasculitis at baseline visit, uveitis duration, and country/study sites as risk factors for failing both MTX and MMF. The presence of retinal vasculitis posterior to the equator on fluorescein angiogram was associated with failing both MTX and MMF. Conclusion: Retinal vasculitis may be a risk factor for failing multiple antimetabolites. Clinicians could consider more quickly advancing these patients to other medication classes, such as biologics. [ABSTRACT FROM AUTHOR]

Purpose Methods Results Conclusion Some patients taking methotrexate (MTX) or mycophenolate mofetil (MMF) experience intolerable side effects at full doses. We evaluated whether dose reduction affected treatment outcomes in uveitis patients.Subanalysis of the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial. Patients were randomized to receive MTX (25 mg weekly) or MMF (3 g daily). A pre-specified dose reduction protocol could be employed for intolerable side effects. Primary analysis was performed at 6 months.43/194 patients (22%) required dose reduction. 88/151 patients (58%) on maximum doses and 32/43 patients (74%) on reduced doses were deemed treatment successes at 6 months. The odds ratio point estimate (1.60, 95% CI 0.72–3.74) favored dose-reduction but this was not significant. Following reduction, adverse events improved at the subsequent study visit (79 events reduced to 63 events).Dose reduction of antimetabolites was not associated with worse outcomes in this subanalysis of a uveitis trial.

To look at markers to differentiate ocular sarcoidosis from ocular tuberculosis in a high TB endemic population. Retrospective multicenter study involving seven tertiary eyecare centers in India between July 2016 to December 2016. Demographic, clinical and laboratory data were retrieved from respective hospital databases. Group A included biopsy-proven ocular sarcoidosis while group B included ocular tuberculosis. Data from 2726 consecutive patients with uveitis were retrieved from the databases. Group A had 61 cases while group B included 307 cases. The mean age in group A was 43 ± 16.55 years while in group B was 38 ± 13.13 years. Females were more common in group A. Uveitis with low Schirmer test (OR-30, CI-95%), candlewax retinal vasculitis (OR-8.69, CI-95%), hilar lymphadenopathy (OR-15.23, CI-95%), fissural nodules (OR-39.11, CI-95%) had higher odds of having ocular sarcoidosis. Presence of dry eye, candlewax retinal vasculitis, hilar lymphadenopathy, and fissural nodules if present in a patient with uveitis, could help differentiate ocular sarcoidosis from ocular tuberculosis in a high TB endemic population.

Sub-analysis of the FAST Trial comparing change in CD4 (∆CD4) from baseline through 12 months in uveitis patients treated with mycophenolate mofetil (MMF) and methotrexate (MTX). Patients were randomly allocated to 1.5 g twice daily MMF or 25 mg weekly MTX. Individuals with CD4 counts at baseline, 6 months (or treatment failure prior), and 12 months (or treatment failure between 6 and 12 months) were included. The association between treatment and ∆CD4 (cells/μL) was analyzed using multivariable linear regression. There was no significant difference in ∆CD4 between MMF and MTX at 6 months (−31.7 cells/μL for MMF compared to MTX; 95% CI: −358.2 to 294.8, P =.85) and 12 months (−78.3 cells/μL for MMF compared to MTX; 95% CI: −468.0 to 311.3; P =.69). There was no significant difference in ∆CD4 between MMF and MTX from baseline to 12 months, suggesting that MMF does not confer additional risk of CD4 lymphopenia in uveitic patients.

Purpose: To develop an algorithm for the diagnosis of Behçet's disease (BD) uveitis based on ocular findings. Methods: Following an initial survey among uveitis experts, we collected multi-center retrospective data on 211 patients with BD uveitis and 207 patients with other uveitides, and identified ocular findings with a high diagnostic odds ratio (DOR). Subsequently, we collected multi-center prospective data on 127 patients with BD uveitis and 322 controls and developed a diagnostic algorithm using Classification and Regression Tree (CART) analysis and expert opinion. Results: We identified 10 items with DOR >5. The items that provided the highest accuracy in CART analysis included superficial retinal infiltrate, signs of occlusive retinal vasculitis, and diffuse retinal capillary leakage as well as the absence of granulomatous anterior uveitis or choroiditis in patients with vitritis. Conclusion: This study provides a diagnostic tree for BD uveitis that needs to be validated in future studies. [ABSTRACT FROM AUTHOR]
