Prevalence and risk factors for serositis in patients with systemic lupus erythematosus: A case-control study.

The overall prevalence of serositis was 9.42%, being significantly higher in men (30%). Therefore, male gender constitutes a risk factor for serositis, and almost one third of men will develop this manifestation, so greater awareness is required in SLE men. CrithidiaDNA+ was also identified as a risk factor, and it should be determined in all SLE patients. Cases significantly received more corticosteroid pulses and higher maximum doses in relation to other SLE severe manifestations, which could imply a more aggressive form of SLE in patients with serositis.
