BACKGROUND: Gastrointestinal tract (GIT) involvement is a common cause of
debilitating symptoms in patients with systemic sclerosis (SSc). There are no
disease modifying therapies for this condition and the treatment remains
symptomatic, largely owing to the lack of a clear understanding of its
pathogenesis. AIMS: To investigate novel aspects of the pathogenesis of
gastrointestinal involvement in SSc. To summarise existing knowledge regarding
the cardinal clinical gastrointestinal manifestations of SSc and its
pathogenesis, emphasising recent investigations that may be valuable in
identifying potentially novel therapeutic targets. METHODS: Electronic
(PubMed/Medline) and manual Google search. RESULTS: The GIT is the most common
internal organ involved in SSc. Any part of the GIT from the mouth to the anus
can be affected. There is substantial variability in clinical manifestations and
disease course and symptoms are nonspecific and overlapping for a particular
anatomical site. Gastrointestinal involvement can occur in the absence of
cutaneous disease. Up to 8% of SSc patients develop severe GIT symptoms. This
subset of patients display increased mortality with only 15% survival at 9 years.
Dysmotiity of the GIT causes the majority of symptoms. Recent investigations have
identified a novel mechanism in the pathogenesis of GIT dysmotility mediated by
functional anti-muscarinic receptor autoantibodies. CONCLUSIONS: Despite
extensive investigation, the pathogenesis of gastrointestinal involvement in
systemic sclerosis remains elusive. Although treatment currently remains
symptomatic, an improved understanding of novel pathogenic mechanisms may allow
the development of potentially highly effective approaches including intravenous
immunoglobulin and microRNA based therapeutic interventions.
