Background Some patients with Systemic Lupus Erythematosus (SLE) have lymphadenopathy (LAP) at diagnosis or at follow-up. The prevalence of LAP in SLE was 59% in the oldest series,1 12% in the 1993 EUROLUPUS series2 and in the last two decades its prevalence was not mentioned. However, the presence of LAP and their histological type may have clinical relevance.3 Objectives To study the prevalence and histologic charasteristics of LAP in a cohort of patients with definite SLE and evaluate its relationship with clinical manifestations. Methods All patients diagnosed with SLE according to the 1997-ACR criteria at the Autoimmunity Units of three different hospitals since 2005 were followed looking for lymph node enlargement at every consult. The moment when LAP was detected, the concomitant clinical symptoms, SLE manifestations and laboratory variables were recorded. The group of patients with and without LAP were compared. A tissue sample was obtained when indicated. All patients agree to participate in the study. Results 103 patients with definite SLE were included in the study. Valuable LAP (>10 mm) was found in 28 patients (27%). The gender and age of SLE patients with and without LAP was similar (80% vs 78% females, and 34±15 vs. 40±28 years respectively). LAP was detected at the time of SLE diagnosis in 54% of patients. Fever was significantly more frequent in patients with LAP (60% vs 5%, p Conclusions Patients con SLE and lymphadenopathy had significantly more fever, cutaneous lesions and serositis. High levels of anti-dsDNA antibodies and hypocomplementemia were more frequent in these patients. In some occasions malignancy could be the cause of lymphadenopathy.
