“…Systemic lupus erythematosus (SLE) is a chronic, multisystem, autoimmune disease that mostly appears in young women. Studies described that SLE is associated with low vitamin D levels in disease expression, relapses, and pathogenesis [ 214 , 283 , 284 , 285 , 286 , 287 , 288 , 289 , 290 , 291 , 292 ].
