Scleroderma causes significant physical stress, is disfiguring, and may decrease normal life expectancy. variable expression; therefore any treatment plan must be alternative yet at the same time focus on the dominating organ disease. The goal of therapy is definitely both to improve quality of life by minimizing specific organ involvement and subsequent life-threatening disease. At the same time the many factors that alter daily function need to be tackled including nutrition, pain, deconditioning, musculoskeletal disuse, co- morbid conditions and the emotional aspects of the disease such as fear, depression and the sociable withdrawal caused by disfigurement. Intro Scleroderma is considered a rare disease with an estimated prevalence in the United States of 276C300 instances per million 1C3 and an incidence of about 20 instances per million per year 2. Females are more commonly affected (4.6 to 1 1) 2 and it tends to be more severe among African and Native People in america than Caucasians4,5. It is rare in children with a maximum age of onset about 45C60 years and has a worse prognosis in older individuals; for example, an increased risk for developing pulmonary hypertension is present with late-age disease onset ( 65 years) 6,7. Scleroderma is definitely a DMXAA (ASA404, Vadimezan) complex polygenetic disease. A recent Genome Wide Association Study (GWAS) confirmed a strong association with the Major Histocompatibility Complex (MHC) and autoimmunity8. Multicase families are uncommon but do occur with a relative risk among first degree relatives of 13 (95% CI 2.9C48.6, p 0.001) with a recurrence DMXAA (ASA404, Vadimezan) rate of 1 1.6% within families versus 0.026% in the general population9. A study of twin pairs showed an overall concordance rate of disease in only 4.7%, a rate that is the same for both monozygotic and dizygotic pairs10. Only circumstantial evidence has implicated certain environmental triggers including silica11 and solvents12. An immune response to cancer is likely another trigger for the disease in a subset of patients13. Scleroderma causes significant physical distress, is usually disfiguring, and can decrease normal life expectancy. The 10-12 months survival has reportedly improved from the 1970s (54C60%) to the 1990s (66C78%)14,15. This improvement is likely due to earlier disease detection and better management of specific organ disease, especially DMXAA (ASA404, Vadimezan) the successful treatment of scleroderma renal crisis with ACE inhibitors. Risk factors for increased mortality include African American race, later age of disease onset, the presence of interstitial lung disease (ILD) or pulmonary hypertension (PH), and higher levels of altered Rodnan skin score or rapid progression of skin disease2,14,16,17. Scleroderma often causes significant disability and general poor quality of life (QOL) 18C20. Dissatisfaction with appearance and interpersonal discomfort due to distress from DMXAA (ASA404, Vadimezan) body image is usually common and often not properly managed21,22. Making a Diagnosis Early detection of scleroderma provides the opportunity to manage the disease process before damage and fibrosis leads to organ failure and poor outcomes. The most common first sign of scleroderma is usually Raynauds phenomenon, a clinical problem of cold and stress induced vasospasm of the digital arteries and cutaneous arterioles involved in body thermoregulation. Raynauds occurs for a variety of reasons in about 3C5% of the general populace23. Most cases are due to primary Raynauds phenomenon, a benign disorder without systemic disease. Primary Raynauds phenomenon usually develops in younger individuals (20sC30s) as compared to scleroderma-associated Raynauds phenomenon. Raynauds TNFRSF9 phenomenon associated with scleroderma is also distinguished from primary Raynauds phenomenon by its positive serologic status, nailfold capillary abnormalities, and severity of the events in frequency, duration and patient related morbidity; it also is usually often accompanied by finger swelling (Physique 1D) and stiffness and/or the presence digital ischemic ulcers or digital tip pitting (Physique 1B). After the onset of Raynauds phenomenon, patients may be otherwise asymptomatic for years or they may rapidly develop other early symptoms and indicators of disease activity such as fatigue, weight loss, musculoskeletal pain, gastrointestinal reflux disease (GERD), nailfold capillary changes (Physique 1A), edema in the extremities or obvious skin thickening.
