Ankylosing spondylitis (AS), psoriatic arthritis, undifferentiated (U) spondyloarthritis (SPA) in india: results from who ilar copcord india program stage i survey 2000–2010

Background: Using a low cost low infrastructure model, the WHO ILAR COPCORD (Community Oriented Program for Control of Rheumatic Diseases) surveys have covered several population in Asia and Latin America. The reported prevalence of AS based on large sample surveys was 0.2–0.3 in China and 0.12 in Iran. We used the Bhigwan COPCORD model to complete comprehensive surveys at several urban and rural site in India. Objectives: To describe the prevalence of SpA in India with a focus on AS Results: 51 741 population (66% rural) in 11 sites all over India was screened using a suitable COPCORD core questionnaire and protocol. Stage I survey was carried out in 3 concurrent overlap phases. House to house visit identified respondents with current/past musculoskeletal pain (last 7 days). Paramedics interviewed respondents to map MSK pain and record patient centric outcome including an Indian version HAQ (Phase 2). Clinical evaluation was carried out by rheumatologists with minimal investigations (Phase 3). The diagnosis was clinical. Survey sites and samples were chosen by convenience. Data was centrally processed and analysed using standard software; significant p<0.05. Data standardised (age-gender) as per; India census 2002 adjusted prevalence reported. Abstract AB1286 – Table 1 Disorder Male (%) Mean age (Range)years Prevalence (95% confidence interval) Spondyloarthritis 44.8 43 (19–80) 0.24 (0.20–0.29) Ankylosing Spondylitis 72.2 39 (19–65) 0.03 (0.02–0.06) Psoriatic Arthritis 64 54 (40–80) 0.02 (0.00–0.03) Undifferentiated SpA 38.4 42 (21–80) 0.19 (0.16–0.23) Abstract AB1286 – Figure 1 Conclusions: The burden of SpA in India (1.2 billion population) is enormous. Compared to global statistics, the prevalence of clinical AS and psoriatic arthritis in the Indian population appears low. References: www.copcord.org Chopra & Nasser.
