Brief summary: The investigators aim to compare the clinical characteristics and outcomes of SLE between male and female Egyptian patients at Assuit University Hospital.

Detailed description: Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown etiology and is characterized by a multifaceted clinical presentation and disease course. Female predominance is a well-known characteristic of SLE, particularly during the reproductive years. Sex differences are another peculiarity of SLE with respect to clinical manifestations and outcomes. Previous studies have recognized male patients with lupus as a distinct minority; such patients often exhibit a poorer prognosis, especially involving the renal, cardiovascular, and neurologic systems. Higher mortality rates in male than in female patients with SLE have also been reported. Andrade et al reported that multiple conditions (for example, severe skin lesions, serositis, thrombotic events, and seizures) are more frequent in males than females.

Lu et al investigated the frequency of renal failure and end-stage renal disease among both genders and found out that these conditions were more prevalent among males. Another study shows no difference in complications and prognosis between both genders.

The results of these previous studies may not be applicable to all ethnic groups. For example, Mok et al studied the males in the local Chinese population had different disease features in term of clinical features at diagnosis, rate, and severity of relapse, organ damage and cumulative damage score. They found through a retrospective review that at the time of diagnosis, there was a trend, however not statistically significant, that males had less Raynaud's, alopecia, arthritis, anti-Ro antibody, but more thrombocytopenia and discoid lesions. Also, a significantly higher number of males had impaired renal functions.

There are few studies that have assessed the differences between male and female Egyptian patients with SLE according to the presentation, complication, prognosis, and mortality. One of these studies shows a more aggressive disease detected in male patients. This was evident by a higher prevalence of nephritis, fever, cutaneous vasculitis in male patients. on the other hand, alopecia and arthritis were significantly higher in females.
