Scleroderma is a rare disease. Approximately 80% of patients are females, and one-half present before the age of 40. Some studies suggest a higher incidence and severity of disease in black females than in whites. Scleroderma affect approximately 20 new patients per million per year and has an estimated prevalence of approximately 250 patients per million in the United States, the synonyms from...

Scleroderma, which follows rheumatoid arthritis and systemic lupus erythematosus as the third most prevalent rheumatic disorder, is poorly understood. Connective tissue abnormalities have been explored extensively (1); recently, vascular involvement has been emphasized as a unifying pathogenetic concept (2, 3). The vascular features in scleroderma include Raynaud's phenomenon; an early, edemato...

OBJECTIVE To determine the presence of antiubiquitin antibody (AUbA) in localised scleroderma and systemic sclerosis, as it is frequently found in the sera of patients with systemic lupus erythematosus (SLE) and has also been shown to have a close relationship with antihistone antibodies that have an important role in scleroderma. METHODS Serum samples from patients with localised scleroderma...

OBJECTIVES There have been many studies suggesting that localized scleroderma has a strong autoimmune background, although the lesions are usually limited to the skin and subcutaneous tissue. Here we summarize previous data on the autoimmunity of localized scleroderma, mostly published in the last two decades, because there has not been a review paper summarizing autoimmunity in this disorder. ...

Systemic sclerosis is a systemic, inflammatory, autoimmune disease affecting the skin and viscera, manifesting pathologically with microvascular lesions, perivascular infiltration by mononuclear cells and increased deposition of extracellular collagen. The rarity of the disease as well as its propensity to appear in the early 1940s, explain the low frequency of concurrent scleroderma and pregna...

OBJECTIVES To evaluate the prevalence and clinical significance of cathepsin G antibodies in patients affected with systemic sclerosis (SSc, scleroderma). METHODS 115 patients affected by SSc, 55 (47,8%) with diffuse scleroderma (dSSc) and 60 (52,2%) with limited scleroderma (lSSc), were tested for cathepsin G antibodies by ELISA method. Moreover these sera were evaluated by indirect immunofl...

High resolution computed tomography (HRCT) was recently demonstrated to be as good as open lung biopsy for the diagnosis of pulmonary involvement in patients with scleroderma. Nevertheless, in view of its price and related irradiation, HRCT cannot be recommended as a screening test. Serum III procollagen (sPIIINP) is an aminopropeptide of type III collagen, which is released during conversion i...

Nondigital lower extremity ulcers are a difficult to treat complication of scleroderma, and a significant cause of morbidity. The purpose of this study was to evaluate the prevalence of nondigital lower extremity ulcers in scleroderma and describe the associations with autoantibodies and genetic prothrombotic states. A cohort of 249 consecutive scleroderma patients seen in the Georgetown Univer...

INTRODUCTION The aim of the study was to interrogate the genetic architecture and autoimmune pleiotropy of scleroderma susceptibility in the Australian population. METHODS We genotyped individuals from a well-characterized cohort of Australian scleroderma patients with the Immunochip, a custom array enriched for single nucleotide polymorphisms (SNPs) at immune loci. Controls were taken from t...

BACKGROUND Scleroderma is a chronic autoimmune disease characterized by progressive connective tissue sclerosis and microcirculatory changes. Localized scleroderma is considered a limited disease. However, in some cases atrophic and deforming lesions may be observed that hinder the normal development. Literature reports indicate phototherapy as a therapeutic modality with favorable response in ...
