Factors Influencing Polymerase Chain Reaction Outcomes in Patients with Clinically Suspected Ocular Tuberculosis
Journal of Ophthalmic Inflammation and Infection.
Mar, 2014 |
Pubmed ID: 24661354 Polymerase chain reaction (PCR) assay can be a useful method for definitive diagnosis in paucibacillary infections such as ocular tuberculosis (TB). In this study, we have evaluated factors affecting PCR outcomes in patients with clinically suspected ocular TB. Patients with clinically suspected ocular TB were investigated by PCR of aqueous or vitreous samples. Three control groups were also tested: group 1 included culture-proven non-tuberculous endophthalmitis, group 2 culture-negative non-tuberculous endophthalmitis, and group 3 patients undergoing surgery for uncomplicated cataract. PCR targeted one or more of following targets: IS6110, MPB64, and protein b genes of Mycobacterium tuberculosis complex. Multiple regression analysis (5% level of significance) was done to evaluate the associations between positive PCR outcome and laterality of disease, tuberculin skin test (TST)/interferon-gamma release assay (IGRA), chest radiography, and type of sample (aqueous or vitreous). The main outcome measures were positive PCR by one or more gene targets, and factors influencing positive PCR outcomes.

Dataset of Tear Film Cytokine Levels in Dry Eye Disease (DED) Patients with and Without HIV Infection
Data in Brief.
Feb, 2017 |
Pubmed ID: 27942559 The tear film cytokine profiling data in this article was obtained from a prospective case-control study with a sample size of 34 dry eye disease (DED) patients with HIV infection and 32 DED patients without HIV infection, see "A distinct cytokines profile in tear film of dry eye disease (DED) patients with HIV infection" (R. Agrawal, P.K. Balne, A. Veerappan, V.B. Au, B. Lee, E. Loo, A. Ghosh, L. Tong, S.C. Teoh, J. Connolly, P. Tan, 2016) [1]. Tear samples were collected from all the subjects using Schirmer׳s strips and cytokine profiling was done using the Luminex bead based multiplex assay with a panel of 41 analytes. The cytokine level differences in each group of subjects were analyzed using logistic regression models.

Zika Virus and Eye
Ocular Immunology and Inflammation.
Mar, 2017 |
Pubmed ID: 28318359 Zika virus (ZIKV), a mosquito-borne flavivirus, is the latest global health concern. Transmission is mainly via Aedes mosquitoes and the infection can be diagnosed on molecular or serologic testings. It typically causes a mild self-remitting illness of low-grade fever, maculopapular rash, and myalgia, but when severe, it is associated with neurological deficits and congenital structural defects. Ocular manifestations are usually mild like nonpurulent conjunctivitis in adults, though it may be linked to uveitis, maculopathy, and hypertensive iridocyclitis. Ocular signs seem to be more significant in congenital ZIKV-macular pigment mottling, neuroretinal atrophy with macular involvement, iris coloboma, and changes in retinal vasculature are noted in infants with infected mothers. Risk factors include ZIKV infection in first trimester and smaller cephalic diameter at birth. Hence, ophthalmic examination in newborns is now recommended. Currently, prevention and active surveillance are integral as there is no known vaccine, and treatment is only symptomatic.
