Scleroderma is a abiding autoimmune disease characterized by fibrosis (or hardening), vascular alterations, and autoantibodies. There are two above forms: Limited cutaneous scleroderma (or morphea)1 mainly affects the hands, accoutrements and face, although pulmonary hypertension is frequent. Diffuse cutaneous scleroderma (or systemic sclerosis)2 is rapidly advanced and affects a ample breadth of the derma and one or added centralized organs, frequently the kidneys, esophagus, affection and lungs, and can be fatal. There are no treatments for scleroderma itself, but alone agency arrangement complications are treated.34
Prognosis is acceptable for bound cutaneous scleroderma. Cast is worse for broadcast cutaneous disease, decidedly in earlier age, and for males. Death occurs a lot of generally from pulmonary, affection and branch complications. In broadcast cutaneous disease, 5-year adaptation is 70%, 10-year adaptation 55%.5
The could could could could cause is unknown. Scleroderma runs in families, but the genes accept not been identified. It affects the baby claret argosy accepted as arterioles, in all organs. First, the endothelial cells of the arteriole die off, forth with bland beef cells, by a action of apoptosis. They are replaced by collagen and added coarse material. Anarchic cells, decidedly CD4+ abettor T cells, access the arteriole, and could could could could cause added damage. Many of the anarchic and annihilative protein signals accept been identified, and they are abeyant targets for drugs that could arrest the process.3

Scleroderma is characterized by the actualization of belted or diffuse, hard, smooth, ivory-colored areas that are immobile, and which accord the actualization of accepted skin, a ache occurring in both localized and systemic forms:6
This ache is begin a part of all contest worldwide, but women are four times added acceptable to advance scleroderma than men. In the United States, about one being in 1,000 is affected. Children rarely ache the systemic type, but localized scleroderma is common. A lot of adults are diagnosed afterwards their 30th altogether and afore age 50. The ache has top ante a part of the built-in American Choctaw association and African-American females.7
Typical scleroderma is classically authentic as balanced derma thickening, with about 90% of cases aswell presenting with Raynaud's phenomenon, nail-fold capillary changes, and anti-nuclear antibodies. Patients may or may not acquaintance systemic agency involvement. Atypical scleroderma may appearance any aberration of these changes after derma changes or with feel abscess only.89 Additional affection of scleroderma about present themselves aural two years of Raynaud's phenomenon.7
Laboratory testing can appearance anti-topoisomerase antibodies (causing a broadcast systemic form), or anti-centromere antibodies (causing a bound systemic form, and the CREST syndrome). Added autoantibodies can be seen, such as anti-U3 or anti-RNA polymerase.
Severe complications from Scleroderma include:
There is no absolute cure for scleroderma. Because the exact could could could could cause is unknown, any analysis is patient-specific and aimed at ameliorating affection of the disease. For example, patients who acquaintance Raynaud's phenomenon may be advised with agents to access claret breeze to the fingers, including nifedipine, amlodipine, diltiazem, felodipine, or nicardipine.
Fibrosis of the derma has been advised with capricious degrees of success with agents such as d-penicillamine, colchicine, PUVA, Relaxin, and cyclosporine.
Because scleroderma is an autoimmune disease, one of the above pillars of analysis involves the use of immunosuppressive agents. These drugs cover methotrexate, cyclophosphamide, azathioprine, and mycophenolate.1011
Individuals with morphea or bound scleroderma accept a almost absolute outlook. They will usually accede to addition disease, not the scleroderma. Those with actual boundless derma and agency captivation (systemic) accept a abrogating prognosis. Added women accept scleroderma, but the ache kills added men. Following diagnosis, two-thirds of patients reside at atomic 11 years. The college the patient's age at diagnosis, the added acceptable they are to die from the disease.
Cases of derma ache agnate to scleroderma may be begin in the writings of Hippocrates as far aback as 460–370 B.C. Oribasius (325–403 A.D.) and Paulus Agineta (625–690 A.D.), aswell wrote on the subject. It is difficult for us to apperceive if these were absolutely examples of scleroderma because the descriptions were inexact.
The aboriginal audible description of the ache was by Carlo Curzio in a album appear in Naples in 1753. This annual produced ample absorption in French and English medical circles.
The annual apropos a adolescent woman of 17 called Patrizia Galiera, who was accepted to the hospital and assigned to Dr. Curzio. Her affection as declared by the doctor complex acerbity of the derma (differing in amount from abode to place), binding about the mouth, and acerbity about the neck. He acclaimed accident of amore in the derma but no added botheration in pulse, respiration, or digestion.
Much of the address contains data of the treatment, which included balmy milk and breath baths, bleeding from the foot, and baby doses of quicksilver. Afterwards 11 months, the derma became bendable and flexible, and all accustomed functions were restored.
Curzio's observations were appear in French in 1755 and angry ample interest. The aboriginal dermatological texts of R. William in London (1808) and his student, J. L. Alibert, in Paris (1818) referred to Curzio's observation.12
