Post-infection immunocomplex glomerulonephritis and Legionnaires' disease in a patient with adult Still's disease during treatment with interleukin 1 receptor antagonist anakinra: a case report


Scholtze, D; Varga, Z; Imhof, A (2011). Post-infection immunocomplex glomerulonephritis and Legionnaires' disease in a patient with adult Still's disease during treatment with interleukin 1 receptor antagonist anakinra: a case report. Journal of Medical Case Reports, 5:299.

Abstract

ABSTRACT: INTRODUCTION: Legionellosis is a systemic disease that primarily affects the lungs. However, dysfunction in many organ systems, including the kidneys, has also been described. There are only a few reported cases of renal dysfunction in patients with legionellosis. CASE PRESENTATION: A 27-year-old Caucasian woman with known adult Still's disease was admitted to our hospital for community-acquired pneumonia, due to Legionella infection, with acute renal failure. Although her respiratory symptoms responded well to antibiotic treatment, her renal function worsened, with severe proteinuria and edema. A renal biopsy showed extracapillary and endocapillary proliferative glomerulonephritis with accompanying chronic and acute interstitial nephritis. This was consistent with a post-infection immunocomplex glomerulonephritis. After initiation of steroid therapy, her renal function improved. Additionally, therapy with diuretics and an angiotensin-converting enzyme inhibitor was initiated because of persistent proteinuria. Under this treatment regimen, her severe edema and proteinuria disappeared. CONCLUSION: To the best of our knowledge, there is only a handful of reported cases of post-infection glomerulonephritis with a nephrotic syndrome in a patient with legionellosis. Our findings suggest that, in patients with Legionnaires' disease with renal failure, post-infection immunocomplex glomerulonephritis should be considered and steroid therapy may be an effective modality to treat the renal complication.

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.
