Clinical, radiologic and serologic profile of patients with interstitial pneumonia with autoimmune features: a cross-sectional study.

The current study aimed to characterize patients from a rheumatology referral center in north India, who satisfied the definition of interstitial pneumonia with autoimmune features (IPAF) as given by the American Thoracic Society and European Respiratory Society (ATS/ERS) consensus committee in 2015. Thirty-five adult patients aged 18 years and above, fulfilling the 2015 ATS/ERS criteria for IPAF were included in the study. The clinical and immunological profile, and radiologic findings on high-resolution computerized tomography thorax were noted.

Prevalence of hydroxychloroquine retinopathy with long-term use in a cohort of Indian patients with rheumatic diseases.

The study aims to estimate the prevalence of hydroxychloroquine (HCQ) retinopathy in a cohort of Indian patients and analyse the associated factors. Adult patients with rheumatological disorders aged ≥ 18 years using HCQ for more than 5 years and/or having received a cumulative dose > 400 g were included. Demographic and clinical data were collected and all underwent ophthalmological tests which included Humphrey automated visual fields (AVF) and spectral domain optical coherence tomography (SD-OCT).

Prevalence of liver fibrosis by Fibroscan in patients on long-term methotrexate therapy for rheumatoid arthritis.

Introduction: Data on the long-term use of methotrexate (MTX) causing liver fibrosis in patients with rheumatoid arthritis (RA) is sparse. Liver biopsy is the gold standard to assess fibrosis but is an invasive procedure. Transient elastography (TE) by Fibroscan is a noninvasive validated tool to detect and quantify liver fibrosis.

Reevaluating the true diagnostic accuracy of dipstick tests to diagnose urinary tract infection using Bayesian latent class analysis.

Objective: Previous studies on diagnostic accuracy of dipstick testing for leukocyte esterase (LE) and nitrite to diagnose urinary tract infection (UTI) had used urine culture, which is an imperfect gold standard. Estimates of diagnostic accuracy obtained using the classical gold standard framework might not reflect the true diagnostic accuracy of dipstick tests.

Methods: We used the dataset from a prospective, observational study conducted in the emergency department of a teaching hospital in southern India.
