Abstract

Objective: Systemic lupus erythematosus (SLE) rarely has a late onset. Late-onset SLE (LSLE) has a milder course and less organ involvement. The purpose of the present study was to compare the clinical and laboratory (lab) findings of SLE regarding age at onset.


Materials and methods
: Seventy-two patients with SLE were included in the study. The age at onset was considered adult-onset SLE (ASLE) if it was <50 years and LSLE if it was ≥50 years. Lab parameters and clinical findings were compared accordingly.


Results
: Overall, 41 (56.9%) patients had ASLE, and 31 (43.05%) patients had LSLE based on the age at onset. The ratio of female-to-male patients was higher in ASLE, and no significant difference was found with regard to gender distribution (12.6:1 and 5.2:1 for ASLE and LSLE, respectively; p=0.239). While malar rash and fever were more common in ASLE, no difference was found regarding the other clinical findings. Only IgG anti-cardiolipin was more common in LSE between the lab parameters.


Conclusions
: Although it is known that LSLE has a milder course and less organ involvement, there are differences in clinical and lab findings and organ involvement in various studies. The results of our study showed no significant difference in organ involvement between ASLE and LSLE.
