There are no established direct causes of systemic lupus erythematosus. Common contributory factors in the development of systemic lupus erythematosus include [[genetic]] predisposition, [[Auto-immune disease|auto-immune diseases]], and use of drugs. Less common factors include environmental factors and exposure to [[Ultraviolet light|ultraviolet (UV) light.]]

Despite the dramatic rise in '''lupus''' research in recent years, the exact cause of the disease remains unknown.  Indeed, consensus is still lacking on whether lupus is a single condition or a group of related diseases. [[SLE]] is a chronic [[inflammation|inflammatory]] disease believed to be a [[Hypersensitivity#Type III - immune complex|type III hypersensitivity]] response with potential [[Hypersensitivity#Type 2 - antibody-dependent|type II]] involvement,<ref>[http://pathmicro.med.sc.edu/ghaffar/hyper00.htm University of South Carolina lecture on immunology]</ref> characterized by the body's production of antibodies against the nuclear components of its own cells. There are three mechanisms by which lupus is thought to develop:
** [[Epstein-Barr virus|Epstein-Barr virus (EBV)]]
* Genetic predisposition
** [[Trypanosomiasis]]
* Environmental triggers
** [[Mycobacterial infection|Mycobacterial infections]] 
* Drug reaction ([[drug-induced lupus]]) - here are about 400 medications currently in use that can cause this condition, though the most common drugs are

Overview

There are no established direct causes of systemic lupus erythematosus. Common contributory factors in the development of systemic lupus erythematosus include genetic predisposition, auto-immune diseases, and use of drugs. Less common factors include environmental factors and exposure to ultraviolet (UV) light.

Causes

  • Exposure to ultraviolet (UV) light[3]
    • Can exacerbate or induce systemic manifestations of SLE 
  • Drug-induced lupus
