[Current treatment of systemic scleroderma]

[Systemic sclerosis]

BACKGROUND

Systemic sclerosis (SSc) is a very heterogeneous, chronic, rare, but socioeconomically important disease with a severe disease course and severe impairment of the quality of life of affected patients.

OBJECTIVES

Overview of the current state of research on the pathogenesis, diagnosis and therapy of SSc.

METHODS

A literature search was performed.

RESULTS

The pathogenesis of SSc is not fully understood. ACR/EULAR criteria allow the diagnosis of early forms of SSc. Classification into limited cutaneous SSc and diffuse cutaneous SSc is of prognostic and therapeutic relevance. New organ-specific treatment options for SSc have led to improved quality of life and prognosis.

[The skin and rheumatism]

The skin is commonly affected in chronic inflammatory disorders and may act as a visual marker for internal or systemic inflammation. Frequent inflammatory skin diseases, like psoriasis and atopic dermatitis (AD), are associated with rheumatic and inflammatory bowel diseases. Metabolic, mental and cardiovascular comorbidity are frequent consequences of chronic inflammation. Further intersections between skin and joints are connective tissue diseases (collagenoses) and can be observed in complex diseases, e.g. systemic lupus erythematosus. Clinically, these diseases range from predominant cutaneous to severe systemic implication of several organs. Localized scleroderma should be clinically distinguished from systemic sclerosis and treated sufficiently to avoid long-term damage and disability. Thus, interdisciplinary disease management is of crucial importance.

[Sclerosing skin diseases]

Sclerosing skin manifestations are more a symptom than a diagnosis and must therefore be meticulously clarified. Systemic scleroderma as a multiorgan disease must be distinguished from localized scleroderma or morphea because in addition to a different clinical picture they have a different prognosis and necessitate other therapeutic procedures. Rare sclerosing skin diseases with implications for internal medicine are eosinophilic fasciitis, Buschke's scleredema adultorum, scleromyxedema and nephrogenic systemic fibrosis.
