परिभाषा

Scleroderma is a rare disease of the connective tissue. It can cause the tissue in skin, joints, and internal organs to thicken and stiffen. There are three major forms of the disease:

  • Localized scleroderma (also known as morphea)—usually affects only the skin in isolated parts of the body. This form is less serious.
  • Systemic scleroderma—affects widespread areas of skin and/or internal organs, most often the lungs (Certain categories of this form of scleroderma are more serious and can be fatal.)
  • Overlap syndrome—may involve features of scleroderma and features of other autoimmune syndromes

का कारण बनता है

Overproduction of collagen and other connective tissue proteins is the main feature of scleroderma. It is not clear what causes this overproduction. Malfunction of the immune system may contribute to excess collagen production. There is also evidence that scleroderma may result from vascular abnormalities.

जोखिम कारक

These factors increase your chance of developing scleroderma. Tell your doctor if you have any of these risk factors:

  • Sex: Female
  • Age: 30-50 years
  • Occupational exposures (such as, polyvinyl chloride or silica dust)
  • Genetic predisposition

लक्षण

Localized Scleroderma

Symptoms are usually restricted to the skin. This disorder does not progress to involve internal organs. The त्वचा क्षति may completely reverse themselves in a few months or a few years. In some cases, they lead to permanent disfigurement. Symptoms include:

  • Hard patches on the skin, most often on the face or trunk (morphea)
  • Lines of thickened skin that can extend to underlying muscles and bones (linear scleroderma or linear morphea)

Systemic Scleroderma

This form of the disease is typically categorized as either limited or diffuse disease. Many cases of limited disease begin gradually with Raynaud’s phenomenon. This involves swelling, tingling, numbness, blue and white color, and pain in fingers and toes. It is brought on by cold or emotional distress. The condition can progress over the years to thickened skin.

Diffuse scleroderma comes on more suddenly and can progress to involve not only the skin but the internal organs. Other symptoms of diffuse scleroderma may include:

  • Diffuse thickening and hardening of the skin
  • Joint and muscular pain, stiffness, and swelling
  • Problems with breathing, swallowing, and digesting food due to thickening and hardening of lung, esophagus, bowel tissues
  • Inflammation and thickening of large and small blood vessels

Complications of diffuse scleroderma can affect virtually every system of the body. Prominent complications include:

  • खून बह रहा है
  • Pulmonary hypertension
  • Heart rhythm problems
  • दिल की धड़कन रुकना
  • Kidney failure
  • उच्च रक्तचाप
  • गैंग्रीन को समझें

निदान

The doctor will ask about your symptoms and medical history, and perform a physical exam. Diagnosis is based on changes in the skin. Other tests may include:

  • रक्त परीक्षण
  • Esophagus motility study
  • एक्स-रे-एक परीक्षण जो शरीर के अंदर संरचनाओं, विशेष रूप से हड्डियों की तस्वीर लेने के लिए विकिरण का उपयोग करता है
  • MRI scan—a test that uses magnetic waves to make pictures of structures inside the body
  • सीटी स्कैन- एक प्रकार का एक्स-रे जो शरीर के अंदर संरचनाओं के चित्र बनाने के लिए कंप्यूटर का उपयोग करता है
  • Biopsies of skin and other tissues—removal of a sample of tissue to test

उपचार

There is no treatment to cure scleroderma. Treatments are aimed at relieving symptoms.

Joints and Muscles

  • एस्पिरिन
  • नॉन स्टेरिओडल आग रहित दवाई
  • Corticosteroids, or prednisone (Deltasone, Orasone, Prednicen-M)

Esophagus and Digestive Tract

  • Medicines to limit acid production in the stomach
  • Small, frequent meals
  • Sleeping with your head elevated to avoid acid reflux

Skin and Internal Organs

  • Corticosteroids
  • Immune suppressants, or azathioprine (Imuran, Azasan)
  • फोटोथेरेपी

Kidney Problems and/or High Blood Pressure

  • Angiotensin-converting enzyme (ACE) inhibitors and other antihypertensive drugs
  • Gleevec (imatinib mesylate)—already approved for the treatment of certain leukemias; used in several trials and may inhibit the production of fibrosis in scleroderma
  • Pulmonary hypertension treatment (such as, bosentan, sildenafil)

Raynaud’s Phenomenon

  • Calcium channel blockers, like nifedipine (Adalat, Procardia, Afeditab, Nifediac)—to dilate blood vessels in the extremities
  • Proper shelter and clothing to avoid cold
  • Not smoking

Restricted Mobility

  • Physical therapy and exercise to maintain circulation, joint flexibility, and muscle strength

रोकथाम

There are no guidelines for preventing scleroderma because the cause is unknown.
