Enterobacter cloacae osteomyelitis induced post-infectious glomerulonephritis on diabetic nephropathy with progressive renal failure

Infection has been well documented to cause glomerulonephritis (GN), with Streptococcus being the most common pathogen. However, the pattern of the disease has changed over recent decades [1–3]. The bacterial flora now comprises Staphylococcus and Gram-negative strains, and the focus of infection is wider than the throat and the skin [1]. GN secondary to osteomyelitis has rarely been reported. We report a case of immune complex-mediated diffuse proliferative GN with acute on chronic renal failure, superimposed on diabetic nephropathy due to osteomyelitis caused by Enterobacter cloacae.
