[Case Report] Glomerulonephritis triggered by a chronically infected left ventricular assist device

A 55-year-old man on the waiting list for heart transplantation with severe dilated cardiomyopathy was admitted for evaluation of low-grade fever in October, 2014. He had had a left ventricular assist device (LVAD; HeartMate II) implanted as a bridge to transplant 4 years previously. Examination was unremarkable. Investigations showed acute kidney injury (serum creatinine increased to 354 μmol/L from 124 μmol/L 2 months previously), raised C-reactive protein, and raised procalcitonin. Urinary protein excretion was 2·2 g/day and urinalysis showed microhaematuria without dysmorphic erythrocytes or casts; previous urinalyses had been unremarkable.
