“Scleroderma” = more than one syndrome n Localized scleroderma or morphea: confined to the skin and subcutaneous structures n n Systemic sclerosis: more uniform skin involvement and the potential for involvment of multiple visceral organs n n Multiple clinical variants Limited, Diffuse, Overlap Syndrome CREST: variant of Limited SSc

Localized Scleroderma n Each of the several forms of localized scleroderma is a disorder

Localized Scleroderma n Each of the several forms of localized scleroderma is a disorder of skin and sometimes the deeper tissues. n The most visible effects of the disease are skin lesions referred to as morphea. n Morphea can be differentiated from SSc by the distribution of lesions (no sclerodactyly or perioral involvement), absence of Raynaud’s and/or periungual telangiectasia, and rarity of severe systemic disease n Age of diagnosis usually 20 -40, linear disease <18 yrs, deep morphea mean age 46

Morphea n The typical morphea lesion begins as a patch of erythema or edema

Morphea n The typical morphea lesion begins as a patch of erythema or edema that may have an associated violaceous border (inflammatory stage). n Primary lesions=hyperpigmented patches. Become progressively indurated, porcelain white or yellow hue. n Upon resolution, atrophy, depigmentation, or hyperpigmentation may occur.

Plaque morphea n n n Involves dermis and, occasionally, the superficial panniculus. Trunk is

Plaque morphea n n n Involves dermis and, occasionally, the superficial panniculus. Trunk is generally more commonly involved than the extremities, although the face, neck, or scalp can be involved. Plaque morphea comprises more than 50% of cases.

n Guttate morphea: This subset usually occurs on the upper trunk. Typically, it presents

n Guttate morphea: This subset usually occurs on the upper trunk. Typically, it presents as multiple oval lesions between 2 -10 mm in diameter. n The lesions often manifest as faint erythema, followed by mild induration and hypopigmentation or hyperpigmentation. n Keloid morphea: This presents as nodules that resemble keloids in the presence of typical morphea.

n Lichen sclerosus et atrophicus: shiny, white plaques often preceded by violaceous discoloration of

n Lichen sclerosus et atrophicus: shiny, white plaques often preceded by violaceous discoloration of the skin; predilection for the anogenital area. n There is higher incidence of autoimmune-related diseases (eg, vitiligo, alopecia areata). n Atrophoderma of Pasini and Pierini: asymptomatic, hyperpigmented atrophic patches with well demarcated "cliff drop borders" on the trunk. n There are no pronounced inflammatory or sclerotic changes. n The course is chronic, with spontaneous resolution usually after 10 years.

n Localized scleroderma including deep and extensive lesions can prevent normal motion of joints

n Localized scleroderma including deep and extensive lesions can prevent normal motion of joints and interfere with daily activities. n However, localized scleroderma does not affect internal organs of the body.

Generalized morphea n n Generalized morphea or linear scleroderma: widespread lesions; thickness and scarring

Generalized morphea n n Generalized morphea or linear scleroderma: widespread lesions; thickness and scarring spreads down to the underlying structures including fat, muscle and, on rare occasion, bone. Disease can be more serious. n n n Individual plaques of morphea become confluent lesions. It can affect more than 2 anatomic sites, including the upper trunk, breasts, abdomen, and upper thighs. Arms, legs, face, neck, and scalp also may be involved. Bullae may develop in localized areas, particularly around the abdomen. Keratoses and calcinosis may occur. Contractures may occur in limbs, and mobility may be restricted.

Linear scleroderma n n One or more linear streaks and induration that can involve

Linear scleroderma n n One or more linear streaks and induration that can involve dermis, subcutaneous tissue, muscle, and bone. It occurs on the extremities, face, or scalp of children and adolescents. n Linear scleroderma: discrete linear induration that primarily affects the extremities. n In more than 90% involvement is unilateral. n Complicated by deformities, joint contractures, and severe limb atrophy. n Can affect the growth of bony structures.

Linear Scleroderma n Lesions en coup de sabre: If the face or scalp is

Linear Scleroderma n Lesions en coup de sabre: If the face or scalp is affected with linear scleroderma, the involvement is often compared to a stroke from a sword (sabre). n Lesions start with contractions and firmness of the skin over the affected area. n Then, an ivory, irregular, sclerotic plaque with hyperpigmentation at the edge will develop. n Progressive hemifacial atrophy (Parry. Romberg syndrome): results in hemiatrophy of the face. n The primary lesions occur in the subcutaneous tissue, muscle, and bone. n The disease usually begins in the first 2

Deep morphea: deep dermis, subcutaneous tissue, fascia, or superficial muscle. n Lesions more diffuse

Deep morphea: deep dermis, subcutaneous tissue, fascia, or superficial muscle. n Lesions more diffuse than in linear scleroderma n Subcutaneous morphea: panniculus or subcutaneous tissue. The onset is rapid, occurring during a period of several months. n More inflammatory condition than other types. n Morphea profunda: entire skin feels thickened, bound down, and taut. Patients develop deep sclerosis of the skin. n Patients younger than 14 years. n The extensor aspect of the extremities and trunk develops sclerotic plaques that extend deep into the subcutaneous tissue, fascia, muscle, and bone. .

Deep morphea: deep dermis, subcutaneous tissue, fascia, or superficial muscle n Disabling pansclerotic morphea

Deep morphea: deep dermis, subcutaneous tissue, fascia, or superficial muscle n Disabling pansclerotic morphea of childhood: aggressive and mutilating generalized, fullthickness involvement of the trunk, extremities, face, and scalp. n Fingertips and toes usually are spared. n Eosinophilic fasciitis: painful peau d'orange appearance involving the extremities, proximal to the hands and feet. n The fascia is the predominant level of involvement. n Patients seem to spontaneously regress or remain unchanged for years.

n The diagnosis of morphea is based on clinical findings, although histopathologic confirmation is

n The diagnosis of morphea is based on clinical findings, although histopathologic confirmation is often needed to exclude other disorders n Eosinophilia can be seen in generalized and linear scleroderma and often correlates with extent of disease. n Polyclonal hypergammaglobulinemia can occur in 50% of patients with linear scleroderma

Autoantibodies? n Most titers correlate with the burden of skin disease antinuclear antibodies (46%-80%)

Autoantibodies? n Most titers correlate with the burden of skin disease antinuclear antibodies (46%-80%) n anti–single-stranded DNA antibodies (50%) n antihistone antibodies (47%). n The presence of rheumatoid factor (60% of cases) may predict articular involvment n Although anticentromere antibodies have been detected in up to 12% of patients with morphea, anti-topoisomerase I antibodies have only been reported in a handful of cases. n

n n n Progression to SSc is rare (0. 9%-5. 7% of cohorts) Despite this, certain extra-cutaneous manifestations can occur. Arthralgias commonly occur, then resolve with progression of skin disease. Other findings: synovitis, uveitis, congenital vertebral abnormalities (especially spina bifida), cardiomyopathies, fever, and lymphadenopathy. Raynaud’s and carpal tunnel syndrome can develop as a secondary result of extensive extremity fibrosis.

n n n The pathogenesis is initiated by microvascular injury (i). This induces inflammation

n n n The pathogenesis is initiated by microvascular injury (i). This induces inflammation and autoimmunity (ii), which have direct and indirect roles in inducing fibroblast activation (iii), a key event in the development of fibrosis. The number of fibroblasts and their precursors in affected tissues is increased by trafficking as well as by the differentiation of mesenchymal cells (iv). Activated myofibroblasts in the lesional tissue perform a series of functions

Transforming growth factor–b n Stimulates cell growth, apoptosis, and differentiation n Promotes collagen and matrix protein production n Decreases the synthesis of collagen-degrading metalloproteinases n Stimulates fibroblasts to maintain an activated state. n Stimulates CTGF synthesis in fibroblasts, vascular smooth muscles, and endothelial cells. n n CTGF can trigger angiogenesis, apoptosis, chemotaxis, extracellular matrix formation, and the structural organization of connective tissues. Non–TGFb–related pathways that involve the activities of p 38 kinase, C-delta kinase, and phosphatidylcholine phospholipase C kinase may also play a role

n Genetics likely predisposes patients to the disease, but whether scleroderma is the result

n Genetics likely predisposes patients to the disease, but whether scleroderma is the result of some combination of genetic factors and other exposures is unknown. n Some data suggests that exposure to industrial solvents or an environmental agent may play a role in predisposing to scleroderma. n Scleroderma-like syndromes also have been clearly linked to agents as varied as contaminated rapeseed oil, polyvinylchloride, and a contaminant in one preparation of L-tryptophan. n Majority of patients with scleroderma do not have a history of exposure to any suspicious toxins.

PAH n Pulmonary hypertension is more common than previously thought (up to 30% of patients) and can occur early. n Signs of pulmonary arterial hypertension (PAH) occur in approximately 10% to 15% patients with SSc but may be found on echocardiogram or right heart catheterization in 20% to 40% of patients. n There are 3 patterns of PAH: n n severe isolated PAH without significant interstitial fibrosis, which occurs predominantly in patients with lc. SSc after 10 to 30 years; PAH complicating interstitial pulmonary fibrosis, which occurs predominantly in dc. SSc patients

n Third type of pulmonary vascular disease reflects the combined vascular and fibrotic pathologic processes of the disease and results in a more indolent pulmonary process. n n Found in those patients who have very slow progressive PAH and who have a secondary pulmonary vascular component in the context of relatively mild fibrosis, distinct from the severe interstitial process seen in true secondary PAH. Symptomatically, patients will present with progressive dyspnea but, in late PAH, may present with syncopy.

Renal n Kidney involvement in SSc may be manifested by scleroderma renal crisis (SRC). n Scleroderma renal crisis used to be the most severe complication in scleroderma and the most frequent cause of the death in these patients.

Renal n Over the last 20 to 25 years, ACE-I have dramatically improved SRC

Renal n Over the last 20 to 25 years, ACE-I have dramatically improved SRC outcome. n Although death and dialysis within 6 weeks were common before the advent of aggressive ACE inhibitor use, 60% of patients with SRC no longer require dialysis or require only temporary dialysis. n Clinically evident renal involvement is almost exclusive to persons with dc. SSc, especially those with rapidly progressive skin thickening than 5 years in duration.

n Microangiopathic hemolytic anemia with thrombocytopenia frequently occurs n Non renal crisis abnormalities: n Mild proteinuria, mild elevation in the plasma creatinine concentration, and/or hypertension are observed in as many as 50% of patients. n Impaired renal reserve may be present in patients in the absence of clinical renal disease. n Clinically evident disease is less common, but autopsy studies suggest that 60% to 80% of patients with dc. SSc have pathologic evidence of renal involvement

Treatment n Prompt detection is the most important aspect of therapy for renal crisis.

Treatment n Prompt detection is the most important aspect of therapy for renal crisis. n Patients with early dc. SSc are advised to take their blood pressure every several days to weekly and to report a rise of systolic pressure of 30 mm Hg or greater. n ACE inhibitors are the drugs of choice, but early aggressive therapy with other potent antihypertensive agents can also be successful. n Some patients may require dialysis, but most can be maintained on ACE inhibitors, and dialysis can be discontinued after 3 to 24 months. Successful renal transplants have been reported. n

Cardiac n Primary cardiac involvement: myocardial fibrosis, LV or biventricular CHF, myocarditis, pericarditis with or without effusion, valvular abnormalities, or supraventricular or ventricular arrhythmias. n Acute symptomatic pericarditis is unusual. n Left sided congestive heart failure secondary to myocardial fibrosis occurs in fewer than 5% of dc. SSc patients.

Cardiac n Cardiac arrhythmias include complete heart block and other EKG abnormalities. n Valvular

Cardiac n Cardiac arrhythmias include complete heart block and other EKG abnormalities. n Valvular disease usually minor, not hemodynamically significant. n Secondary cardiac disease occurs in association with SSc pulmonary or renal disease or in overlap with other illnesses such as systemic lupus erythematosus or polymyositis.

Treatment n Nonsteroidal anti-inflammatory drugs or low-dose corticosteroids can be used for symptomatic pericarditis.

Treatment n Nonsteroidal anti-inflammatory drugs or low-dose corticosteroids can be used for symptomatic pericarditis. n If myocarditis is identified clinically or by endomyocardial biopsy, high-dose glucocorticoid therapy should be tried. n Digitalis and diuretics are the mainstay of therapy. n The typical progressive left ventricular failure caused bymyocardial fibrosis is unaffected by any therapy and may lead to cardiac transplantation. n Serious arrhythmias are treated in the standard way

MSK n n Manifestations may include muscle weakness and rheumaticcomplaints ranging from simple arthralgias

MSK n n Manifestations may include muscle weakness and rheumaticcomplaints ranging from simple arthralgias to frank arhtritis. In dc. SSc, symptoms often start with symmetric polyarthralgia and joint stiffness (with or without gross synovitis), myalgia, and puffiness of the skin. Joint pain, immobility, and contractures are the result of fibrosis around tendons and other periarticular structures. Contractures of the hands from this process are most common, but large joint contractures involving the wrists, elbows, hips and ankles may also occur.

MSK n Some patients may have palpable and/or audible deep periarticular tendon friction rubs

MSK n Some patients may have palpable and/or audible deep periarticular tendon friction rubs during motion; this may be due to fibrinous tenosynovitis. n Severe arthritis or destructive joint disease should make one suspect an overlap syndrome with rheumatoid arthritis. n 2 principal patterns of muscle involvement n n Scleroderma myopathy, frequently mild and relatively nonprogressive, p/w minor proximal weakness and slight to moderate elevations of CPK Sclerodermatomyositis, a true overlap between scleroderma and polymyositis n n Far less common. Weakness is often more profound, with significantly elevated CPK and EMG/muscle biopsy abnormalities typical for inflammatory myopathy.

Benefits and Survival n After a median follow-up of 5. 3 (1– 7. 5) years 81% (n=21/26) of the patients demonstrated a clinically beneficial response. n The Kaplan–Meier estimated survival at 5 years was 96. 2% (95% CI 89– 100%) and at 7 years 84. 8% (95% CI 70. 2– 100%) and event-free survival, defined as survival without mortality, relapse or progression of SSc, resulting in major organ dysfunction was 64. 3% (95% CI 47. 9– 86%) at 5 years and 57. 1% (95% CI 39. 3– 83%) at 7 years. n The positive effect of HSCT on survival rate needs to be interpreted with care, due to a wide range in the duration of patients’ follow-up and the uncontrolled nature of this study, but the results are encouraging.

Prevention of vascular damage n Prostacyclin analoge: analog poprostenol and treprostinil, benefit exercise capacity, dyspnea score, cardiopulmonary hemodynamics, and survival. n n n The inhaled form of Iloprost, another prostacyclin derivative, is also available in the United States. Data supporting the use of Iloprost in SSc PAH are mostly symptomatic Bosentan: oral mixed endothelin A/B antagonist, which improves PAH because it antagonizes endothelin-1, a potent vasoconstrictor and smooth muscle mitogen. n Two randomized, placebo-controlled studies have shown that bosentan improves exercise capacity, cardiopulmonary hemodynamics, decreased pulmonary vascular resistance, and decrease pulmonary artery pressure.

Prevention of vascular damage n Sildenafil: phosphodiesterase-5 inhibitor causes preferential pulmonary vasodilation, decreases pulmonary vascular resistance index, and improves gas exchange in patients with severe lung fibrosis and secondary pulmonary hypertension n ACE-I: despite rising serum creatinine concentrations while taking an ACE inhibitor, the drug should be continued as part of the antihypertensive therapy.

n Twenty- two months after the diagnosis of limited SSc, her skin thickening began to rapidly progress above elbows and knees, and finally involved the trunk. n Blood pressure was in the normal range. n The diagnosis was converted to SSc of the diffuse cutaneous subset and she was started on D-penicillamine 250 mg/day. n A month later, she visited the emergency room due to the sudden onset of facial edema and severe dyspnea. n Her blood pressure was 220/134 mm. Hg, heart rate 120 beats/ min, respiration rate 48/min, and body temperature 35℃. n She reported that the dyspnea had begun 10 days previously and that her urine output had decreased markedly.

n A physical examination revealed facial and pre-tibial edema, and pulmonary rales in the whole lung field. n Laboratory data showed hemoglobin at 9. 9 g/d. L, LDH 703 IU/L, total bilirubin 2. 9 mg/d. L, indirect bilirubin 1. 8 mg/d. L, and schistocytes with polychromasia on peripheral blood smear, suggesting intravascular hemolysis. n Antineutrophil cytoplasmic antibody was negative. n Urinalysis and microscopic examination showed mild proteinura (1+), hematuria (≥ 100 RBC per high power field with dysmorphic RBC >90%), and pyuria (20 -29 white blood cells per high power field).
