Abstract:In this review, we analyze the effects of systemic lupus erythematosus and scleroderma on the gastrointestinal tract. There is a wide variation of gastrointestinal manifestations from these autoimmune disorders including but not limited to: oral ulcers, dysphagia, gastroesophageal refl ux disease, abdominal pain, constipation, diarrhea, fecal incontinence, pseudo-obstruction, perforation and gastrointestinal bleeding. The purpose of this review is to discuss these manifestations, the appropriate diagnostic tests, and treatment.Keywords: systemic lupus erythematosus, scleroderma, gastrointestinal manifestations
Systemic Lupus ErythematosusSystemic Lupus Erythematosus (SLE) is a multisystem disease characterized by antinuclear antibodies and complement deposition. The disease affects women more then men (especially African-American women) with a reported female/male ratio of 10:1.1 Gastrointestinal (GI) complications are common in patients with active SLE. In 1895, William Osler was the fi rst to describe how the GI complications of SLE can mimic any type of abdominal condition and overshadow the other organ complications associated with SLE. Gastrointestinal complications can lead to a variety of symptoms across a large portion of the GI tract. Up to 50% of patients will experience anorexia, nausea or vomiting.
Oral Cavity and SLEOral or nasopharyngeal ulceration, usually painless, observed by a physician is one of the eleven diagnostic criteria of SLE. Mucous membrane involvement occurs in 12%-45% of patients. The wide variation may be explained by demographic differences. One cross-sectional analysis reported that 46% of English patients with SLE had oral lesions compared to 15% of patients in Brazil and 11% of patients in Sweden.2 Another study reported oral ulcerations at a prevalence of 26% in an Arab population of SLE patients, and noted a signifi cant association with the presence of anti-smith antibodies (P = 0.033).
3Causes of the mucosal ulcerations include the underlying disease activity, associated Sjogren's syndrome, intra-oral infections and complications associated with treatment.The ulcers are generally classifi ed as either discoid, erythematous or ulcerative. Discoid lesions, characterized by erythema, atrophy, and depigmentation, usually occur on the lips. Punched-out erosions/ ulcers with surrounding erythema, irregularly shaped raised white plaques, and areas of erythema tend to occur on the hard or soft palate and the buccal mucosa. The discoid lesions are painful while the erythematous lesions (the majority) are painless. It has been reported by Jonsson et al that only those patients with active disease can have ulcerative and discoid lesions. However, they found no correlation between overall prevalence of oral lesions and SLE disease activity. 4 The treatment options for oral lesions include topical glucocorticoids, tacrolimus ointment, intralesional corticoids, and systemic antimalarial drugs. Most lesions respond to steroids in days to weeks.
