Anti-RNA-Polymerase-III-Antikörper bei renaler Krise der systemischen Sklerose


Schorn, R; Gaspert, A; Cohen, C D (2010). Anti-RNA-Polymerase-III-Antikörper bei renaler Krise der systemischen Sklerose. Deutsche Medizinische Wochenschrift, 135(22):11118-11121.

Abstract

HISTORY AND CLINICAL FINDINGS: A 67-year old patient underwent a kidney biopsy because of newly diagnosed hypertension, haemolytic anemia with fragmentocytes and acute kidney failure requiring dialysis therapy. The biopsy showed thrombotic microangiopathy. Since last winter Raynaud's phenomenon and changes of hands and lips were recognised. INVESTIGATIONS: Initial immunological tests revealed anti-nuclear antibodies (ANA) but neither anti-centromere nor anti-Scl70 antibodies. The positive analysis of anti-RNA polymerase III antibodies confirmed the clinical suspicion of scleroderma renal crisis in the setting of first diagnosis of systemic sclerosis. TREATMENT AND COURSE: After diagnosis therapy with lisinopril, candesartan and amlodipin was established. Four months after discharge dialysis dependency persisted. CONCLUSION: Scleroderma renal crisis is an important differential diagnosis in the setting of acute kidney failure. Medical history, clinical examination and immunological test confirm the diagnosis. The mainstay of therapy is aggressive blood pressure control with ACE-inhibitors (or angiotensin receptor blocking agents).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
