Pulmonary involvement in early systemic lupus erythematosus

Aim of the workSLE is an autoimmune disease characterized by a variety of clinical and laboratory abnormalities. It may affect many organs and pulmonary involvement is a common finding in SLE. The purpose of this study was to disclose the pulmonary involvement in early SLE patients not more than 2 years of disease duration using the computed tomography (CT) as well as the pulmonary function tests as ways of pulmonary involvement assessment.Patients and methodsForty-two patients aged 29 ± 12.5 with early SLE not more than 2 years of disease duration were recruited for the study. All patients were assessed clinically for their SLE with BILAG which was utilized for disease activity determination.ResultsNine and half percent of our patients were found to be clinically involved by ILD, where 28.6% have abnormal HRCT finding, 26.2% with abnormal PFT. Variants that were associated with an abnormal forced vital capacity FVC < 80% in a significant manner were: smoking, long disease duration, self-reported pulmonary symptoms (p 0.001), BILAG global score (p 0.006), Anti dsDNA (p 0.001), Antiphospholipid (IgM or IgG) (p 0.01), anti Sm (p 0.002), anti-RNP (p 0.005), HRCT abnormalities (p 0.001), current medication of steroid (any dose) (p 0.005), immunomodulator therapy (p 0.002), and Rituximab therapy (p 0.001).ConclusionsILD occurs as early as in the first 2 years in the course of SLE patients. There was a clear predilection of ILD with certain variables in our cohort of patients.
