A case report: Acute kidney injury with progression to chronicity in an eldery woman.

Acute renal failure in elderly patients can be caused by a wide spectrum of diseases that usually have a cause outside the kidney. The most common causes include renal impairment as part of ANCA vasculitis, another category includes clonal plasmatic cell disease with light chain cast nephropathy; and there also exists an increasing number of drug-induced tubulointerstial damage. We present a case of iatrogenic less common form of acute failure in a 73-year-old woman, who did not suffer from any serious disease until then. Although the biopsy helped to determine the cause of the failure and thus affect subsequent therapy, the function did not return to the previous state and the patient progressed to CKD G3bA1 with serum creatinine values of around 170-140 µmol/l.

Renal involvement of a patient with Crohn´s disease: A case report.

Inflammatory bowel disease (IBD) is a group of chronic relapsing intestinal inflammatory processes primarily represented by ulcerative colitis (UC) and Crohn´s disease (CD). Nearly half of IBD cases are followed by extraintestinal complications and renal involvement can occur independatly or along with other complications and are described with the patients sufferring from UC or CD. Most frequent renal involvement is nephrolithiasis, tubulointerstinal nephritis, different kinds of glomerulonephritis and AA amyloidosis. We are presenting an unusal form of renal involvement of a young female patient with a severe form of Crohn´s disease treated with recombinant monoclonal antibodies.
