Overview of Causes of Scleroderma

The cause of scleroderma is generally unknown, however areas being investigated include autoimmunity, environmental exposures, genetics, and infections.

Many researchers feel that several factors work together to induce scleroderma, such as a genetic inclination along with exposure to a toxin or infection which triggers the illness. (Also see: What is Scleroderma?, Types of Scleroderma, and Systemic Sclerosis)

Scleroderma is not believed to be contagious; you cannot get it by hugging or kissing someone or other intimate contact.
There is an increased incidence of certain types other autoimmune diseases and cancer among scleroderma patients. (Also see: Associated Conditions and Cancer and Scleroderma)
Prevention of autoimmune rheumatic disease: state of the art and future perspectives. The road map towards prevention of autoimmune rheumatic diseases includes increased understanding of how genes, environment and immunity interact. Klareskog L. (PubMed) Ann Rheum Dis. 2010 Dec. (Also see: Autoimmunity)

Advanced Glycation Endproducts (AGES)

Noninvasive measurement of skin autofluorescence is increased in patients with systemic sclerosis: an indicator of increased advanced glycation endproducts? Autofluorescence is increased in patients with dcSSc compared to primary RP and to healthy controls. This suggests increased oxidative stress and the potential for autofluorescence as a biomarker. J Rheumatol. 2012 Aug;39(8):1654-8.

Proteins

Increased expression of S100A8 and S100A9 in patients with diffuse cutaneous systemic sclerosis (dcSSc). A correlation with organ involvement and immunological abnormalities. These two proteins may play important roles in the development of systemic sclerosis. PubMed, Clin Rheumatol, 2013 Jun 11.
Researchers implicate well-known protein in fibrosis. We now know that TLR4 plays a role in scleroderma, but much research remains to be done to develop safe and effective drugs to inhibit this pathway. EurekAlert, 11/20/12.
Researchers identify molecular gatekeeper of arthritis. The protein, researchers noted, determines the fate of damaging cells that mistakenly attack the body's own tissues and lead to autoimmune disorders such as rheumatoid arthritis. The finding could help researchers explore new types of treatments for patients whose arthritis has not been effectively treated by other means. OrthoSuperSite. 09/10/10.

Serum TIMP-2

Serum Levels of Tissue Inhibitors of Metalloproteinase 2 in Patients With Systemic Sclerosis (SSc). This study confirms the probable role of TIMP-2 in inducing fibrosis in the course of SSc, and suggests a possible role of TIMP-2 in the development of pulmonary involvement in diffuse scleroderma (dSSc) patients, and cardiac lesions in limited scleroderma (lSSc) patients, with disease duration equal to or more than 2 years. Amira Shahin. (PubMed) Mediators Inflamm. 2006; 2006(6): 38458.

Serum sCD40

Increased Serum Soluble CD40 Levels in Patients with Systemic Sclerosis. Elevated serum sCD40 levels were associated with lcSSc. These results suggest that the blockade of CD40/CD40 ligand interaction could be a potential therapeutic strategy in SSc. J Rheumatol 2007 February;34:353–8. (Also see: Limited Scleroderma)

Tissue Kallikrein (t-kallikrein)

Increased circulating levels of tissue kallikrein in systemic sclerosis correlate with microvascular involvement. T-kallikrein levels are increased in patients with SSc, particularly in lSSc, and are associated with early and active capillaroscopic patterns. T-kallikrein may play a part in SSc microvascular changes. PubMed. Ann Rheum Dis. 2005 Mar;64(3):382-7. (Also see: Raynaud's)
