What is scleroderma (types and symptoms)

What is Scleroderma?

Judy Williamson,
Scleroderma Patient

The word “scleroderma” is Greek for hard skin, the most visible characteristic of the disease. In fact, scleroderma is much more than this; chronic, complex and debilitating, it often affects the internal organs with life-threatening consequences. Depending on the subtype of illness, scleroderma can damage the lungs, kidneys and gastrointestinal tract with grave results. Peripheral vasculature damage due to scleroderma can result in loss of digits or limbs. In some cases, the joints and muscles are affected, resulting in a loss of mobility.

Scleroderma falls into several different disease categories: It is a vascular disease because it can constrict and injure tiny blood vessels. It is a connective tissue disease because it can cause abnormal changes to the skin, tendons and bones. Like many other rheumatic disorders, scleroderma is believed to be an autoimmune disease because the disease can apparently trigger the body to make antibodies against itself.

The symptoms and severity of scleroderma vary from one person to another and the course of the disease is often unpredictable. The number of women affected with scleroderma is disproportionately high with some estimates suggesting as many as four out of every five patients being female. The disease most often strikes between the ages of 20 and 50; however, children and those above age 50 across all ethnic groups are also affected.

Today, there is no way to prevent scleroderma and there is no cure. Treatments are available for some, but not all of the most serious complications of the disease. Current treatments include medications that modulate the immune system, chemotherapy drugs, vasodilators and ACE-inhibitors. Presently, most treatments act to slow the progression of the disease and limit damage rather than truly arresting the disease. In addition, some of the drugs currently in use can have serious side effects. There is much work that remains to be done.

Despite the number of people affected by scleroderma and the devastating effect the disease can have, scleroderma research remains critically underfunded by the National Institutes of Health. Contributions made to the Scleroderma Research Foundation support promising exploratory projects as well as innovative research studies that may provide the basis for longer term investment by federal research funding programs. Until new therapies are made possible by advances in medical research, people living with scleroderma continue to have hope, knowing that scientists are working every day on their behalf.

Screening for PAH in Systemic Sclerosis: Does It Matter?

Author: Kevin Deane, MD
Date Published: February-2012
Source: Medscape Today

ulmonary arterial hypertension (PAH) is a leading cause of mortality in patients with systemic sclerosis (SSc).[1] Once commonly thought to be a late complication of SSc, support for PAH as an early manifestation of disease is growing. PAH is present within 5 years of the onset of the first non-Raynaud symptoms of SSc in approximately 50% of patients.

Stimulation of soluble guanylate cyclase reduces experimental dermal fibrosis

Author: C. Beyer, N. Reich, S. Schindler, et al
Date Published: January-2012
Source: Annals of the Rheumatic Diseases

Fibrosis and vascular disease are cardinal features of systemic sclerosis (SSc). Stimulators of soluble guanylate cyclase (sGC) are vasoactive drugs that are currently being evaluated in phase III clinical trials for pulmonary arterial hypertension.

Emerging patterns of genetic overlap across autoimmune disorders.

Author: Richard-Miceli C, Criswell LA.
Date Published: January-2012
Source: Genome Medicine

Most of the recently identified autoimmunity loci are shared among multiple autoimmune diseases. The pattern of genetic association with autoimmune phenotypes varies, suggesting that certain subgroups of autoimmune diseases are likely to share etiological similarities and underlying mechanisms of disease.

Gender and ethnicity differences in the prevalence of scleroderma-related autoantibodies.

Author: Krzyszczak ME, Li Y, Ross SJ, et al
Date Published: October-2011
Source: Journal of Cellular and Molecular Medicine

Autoantibodies to topoisomerase I (topo I), RNA polymerase III (RNAPIII), centromere, U3RNP/fibrillarin, Th, PM-Scl, and U1RNP found in scleroderma (SSc) are associated with unique clinical subsets. The effects of race and gender on autoantibody prevalence and clinical manifestations were examined.

Elevated expression of cav-1 in a subset of SSc fibroblasts contributes to constitutive Alk1/Smad1 activation.

Author: Haines P, Hant FN, Lafyatis R, Trojanowska M, Bujor AM.
Date Published: January-2012
Source: Journal of Cellular and Molecular Medicine

Previous studies have shown that the TGFβ/Alk1/Smad1 signaling pathway is constitutively activated in a subset of systemic sclerosis (SSc) fibroblasts and this pathway is a critical regulator of CCN2 gene expression. Caveolin-1 (cav-1), an integral membrane protein and the main component of caveolae, has also been implicated in SSc pathogenesis.

An Evaluation of Long-Term Survival From Time of Diagnosis in Pulmonary Arterial Hypertension From REVEAL.

The Registry to EValuate Early And Long-Term Pulmonary Arterial Hypertension Disease Management (REVEAL) was established to characterize the clinical course, treatment, and predictors of outcomes in patients with pulmonary arterial hypertension (PAH) in the US. To date, estimated survival based on time of patient enrollment has been established and reported.

Evidence of the contribution of the X chromosome to systemic sclerosis susceptibility: association with the functional IRAK1 196Phe/532Ser haplotype.

Several autoimmune disorders, including systemic sclerosis (SSc), are characterized by a strong sex bias. To date, it is not known whether genes on the sex chromosomes influence SSc susceptibility. Recently, an IRAK1 haplotype that contains the 196Phe functional variant (rs1059702), located on Xq28, was found to confer susceptibility to systemic lupus erythematosus (SLE).

Mechanism, Potential Therapy for Scleroderma Lung Disease Uncovered

Author: NIAMS / Tourkina E, et al
Date Published: January-2012

Investigators, partially supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases, have found that a deficiency in the protein caveolin-1 (cav-1) is linked to the development of interstitial lung disease, the scarring of lung tissue that causes disability and death in people with scleroderma.
