Awareness, perspectives and satisfaction levels among patients with psoriatic arthritis: a multicentric cross-sectional survey.

Perception of the disease and its management impacts patients with Psoriatic arthritis (PsA) to a great degree. Studies examining patients' viewpoints and perception of their disease and its management are scarce. This multicentric cross-sectional survey was undertaken to understand the perspectives of patients with PsA. A survey questionnaire with items on demographics, awareness about their disease, treatment, physical therapy, quality of life and satisfaction with the care received was designed. After internal and external validation, a pilot survey was conducted, and the questionnaire was finalized. The final survey (with translations in local languages) was carried out at 17 centres across India. There were 262 respondents (56% males) with mean age of 45.14 ± 12.89 years. In 40%, the time lag between onset of symptoms and medical assessment for it was more than a year. In most of the patients, the diagnosis of PsA was made by a rheumatologist. Over 83% of patients were consulting their rheumatologist periodically as advised and fully compliant with the treatment. Lack of time and cost of therapy were the most common reasons for non-adherence to therapy. Eighty-eight patients (34%) were not fully satisfied with their current treatment. Over two-third of patients had never seen a physiotherapist due to barriers including a lack of time, pain, and fatigue. The daily activities and employment status were affected in nearly 50% of patients with PsA. The current survey has identified a gap in patients' awareness levels and helps healthcare providers in understanding the varied perceptions of patients with PsA. Addressing these issues in a systematic manner would potentially improve the treatment approaches, outcomes, and patient satisfaction levels.

Elucidating potential molecular signatures through host-microbe interactions for reactive arthritis and inflammatory bowel disease using combinatorial approach.

Reactive Arthritis (ReA), a rare seronegative inflammatory arthritis, lacks exquisite classification under rheumatic autoimmunity. ReA is solely established using differential clinical diagnosis of the patient cohorts, where pathogenic triggers linked to enteric and urogenital microorganisms e.g. Salmonella, Shigella, Yersinia, Campylobacter, Chlamydia have been reported. Inflammatory Bowel Disease (IBD), an idiopathic enteric disorder co-evolved and attuned to present gut microbiome dysbiosis, can be correlated to the genesis of enteropathic arthropathies like ReA. Gut microbes symbolically modulate immune system homeostasis and are elementary for varied disease patterns in autoimmune disorders. The gut-microbiota axis structured on the core host-microbe interactions execute an imperative role in discerning the etiopathogenesis of ReA and IBD. This study predicts the molecular signatures for ReA with co-evolved IBD through the enveloped host-microbe interactions and microbe-microbe 'interspecies communication', using synonymous gene expression data for selective microbes. We have utilized a combinatorial approach that have concomitant in-silico work-pipeline and experimental validation to corroborate the findings. In-silico analysis involving text mining, metabolic network reconstruction, simulation, filtering, host-microbe interaction, docking and molecular mimicry studies results in robust drug target/s and biomarker/s for co-evolved IBD and ReA. Cross validation of the target/s or biomarker/s was done by targeted gene expression analysis following a non-probabilistic convenience sampling. Studies were performed to substantiate the host-microbe disease network consisting of protein-marker-symptom/disease-pathway-drug associations resulting in possible identification of vital drug targets, biomarkers, pathways and inhibitors for IBD and ReA.Our study identified Na(+)/H(+) anti-porter (NHAA) and Kynureninase (KYNU) to be robust early and essential host-microbe interacting targets for IBD co-evolved ReA. Other vital host-microbe interacting genes, proteins, pathways and drugs include Adenosine Deaminase (ADA), Superoxide Dismutase 2 (SOD2), Catalase (CAT), Angiotensin I Converting Enzyme (ACE), carbon metabolism (folate biosynthesis) and methotrexate. These can serve as potential prognostic/theranostic biomarkers and signatures that can be extrapolated to stratify ReA and related autoimmunity patient cohorts for further pilot studies.

Rheumatoid arthritis with necrotic lung nodules.

Rheumatoid arthritis is a multisystemic in˜flammatory disease. Lungs are the commonest site of extra-articular involvement. Rheumatoid lung nodules occur infrequently and can undergo necrosis giving rise to necrobiotic lung nodules. Infections, malignancy and granulomatosis with polyangiitis are more common causes of cavitating lung nodules. Presence of rheumatoid factor, history of smoking and use of methotrexate increase the chances of developing rheumatoid lung nodulosis. Histopathological examination of the nodule is essential to make a correct diagnosis. We present a 74-year-old male with long-standing rheumatoid arthritis who had multiple cavitating lung nodules. Biopsy from the lung nodule could not be performed as the patient refused to consent. However, infection, malignancy and granulomatosis with polyangiitis were ruled out on the basis of blood investigations and bronchoscopy. He was empirically treated with a moderate dose of glucocorticoid along with conventional synthetic disease-modifying antirheumatic drugs. After three months of treatment, the lung nodules disappeared completely and his articular symptoms showed marked improvement.
