We report a case of acute renal failure in which renal biopsy showed immune complex-mediated proliferative glomerulonephritis. The patient had been afflicted with progressive lower back pain for 2 months. No fever was noted. Magnetic resonance imaging of the lumbar spine demonstrated characteristic findings of vertebral osteomyelitis and bilateral psoas abscesses. Culture of the computed tomogr...

A 78-year-old woman developed acute-onset nephrotic syndrome. A renal biopsy showed mild mesangial proliferative glomerulonephritis. Immunofluorescence studies revealed granular IgG3- λ deposits within the mesangial area and along the glomerular capillary walls. Electron microscopy showed mesangial and subendothelial granular electron-dense deposits. The pattern of deposition was predominantly ...

We report two cases of Lyme disease-associated glomerulonephritis. A 57-year-old female presented with rash, volume overload, hypertension and rapidly progressive glomerulonephritis. Biopsy confirmed an immune complex-mediated, membranoproliferative lesion. She was treated successfully with steroids and antibiotics. In a second case, a 40-year-old male, with a previously known microscopic hemat...

Acute poststreptococcal glomerulonephritis (APSGN) is one of the most common and important renal diseases resulting from a prior infection with group A β-hemolytic streptococcus (GAS) (Ash and Ingulli, 2008). Typical clinical features of the disease include an acute onset with gross hematuria, edema, hypertension and moderate proteinuria (acute nephritic syndrome) 1 to 2 weeks after an antecede...
