Spectrum of initial clinical presentations in Pakistani patients with systemic lupus erythematosus in the Arthritis Care Foundation lupus cohort

Objective: The aim is to determine the pattern of initial clinical presentations of systemic lupus erythematous (SLE) in patients in a Pakistani lupus cohort. Methods: This is a multi-centric, retrospective, descriptive study that was done through the analysis of electronic records of patients registered with outdoor clinics of the Arthritis Care Foundation (ACF) from November 2021 to March 2023. Follow-up records of all patients diagnosed and labeled as SLE as per ACR/EULAR criteria 2019 were reviewed and only those patients whose initial presentation of SLE was documented at their incident visit (after verifying the signs and symptoms from record of their GP/referring physicians' visits) were included in the study. A total of 388 patients diagnosed with SLE were included in the study. Their data was then entered and analyzed by using SPSS 23. The qualitative data was expressed as percentages and numbers while the quantitative variables were expressed as mean and standard deviation. Data correlation was calculated by Chi-Square test, and a p-value of less than 0.05 was considered statistically significant. Results: Of our 388 patients, 360 (92.8%) were females and 28 (7.2%) were males giving a female-to-male ratio of 12:1. The mean age of our patients was 32.8 + 9.8 years. Mucocutaneous manifestations were most commonly reported in our patient group by 336 (86.7%) patients. Musculoskeletal complaints were the next most common presenting feature reported by 246 (61.9%) patients followed by constitutional symptoms in 78 (20.1%) patients, and renal involvement in 42 (10.8%) patients. Conclusion: In our study, a majority of patients presented with mucocutaneous symptoms. It is therefore of paramount importance to suspect autoimmune diseases in patients with these system involvements.

Automated summary

This study aimed to determine the pattern of initial clinical presentations of systemic lupus erythematous (SLE) in a Pakistani lupus cohort. The results showed that mucocutaneous manifestations were the most commonly reported symptoms, indicating the importance of considering autoimmune diseases in patients with these symptoms.
