BACKGROUND Accounts of renal pathological findings in infective endocarditis are mostly based on studies from many years ago. We reviewed a group of patients with infective endocarditis in the light of modern concepts of renal pathology, including the largest reported series of renal biopsies in this condition. METHODS Renal tissue was available for retrospective study from 62 patients with c...

Acute glomerulonephritis (AGN) is a type of renal disease which indicates the inflammation of glomerulus and nephrons. This study was carried on 94 children, <15 years old with the diagnosis of AGN who were admitted to Qom and Yazd's hospitals between 2000 and 2006. Data were collected using hospital records on admission, progression notes and outpatient follow up. Among 94 patients, 55.3% were...

IgA nephropathy is the most common primary glomerulonephritis, but the pathogenesis of IgA nephropathy is still unclear. A 32-year-old woman was found to have IgA nephropathy and acute myeloid leukaemia. She was treated with allogenic bone marrow transplantation (BMT). After BMT, immunoflourescent staining of IgA and proteinuria disappeared. These findings suggest bone marrow cells are involved...

Following the induction of aortic insufficiency, 15 dogs received intravenous injections of either Staphylococcus aureus or Streptococcus mitis. The clinical course and pathologic picture resembled those of acute and subacute bacterial endocarditis respectively. The valvular lesions were confined largely to contacting surfaces of aortic and mitral leaflets. The dogs given S. mitis often develop...

Since the mid-1980s, concern has grown that invasive group A Streptococci (GAS) has been increasing in incidence and severity. Invasive infections caused by group A Streptococcus or Streptococcus pyogenes include sepsis, arthritis, pneumonia, meningitis, necrotizing fasciitis (NF) and streptococcal toxic shock syndrome (STSS). GAS also causes noninvasive suppurative disease as pharyngitis and o...

Henoch-Schönlein purpura (HSP) is the most common small vessel vasculitis of childhood. It is characterized by nonthrombocytopenic palpable purpura, abdominal pain, arthritis, and glomerulonephritis. Although HSP is typically known to be self-limited, serious complications can occur. Acute pancreatitis rarely presents as a complication of HSP. It is even rarer as an initial presenting feature o...

A non-immunocompromised man developed acute Aspergillus pneumonia after spreading mouldy tree bark mulch. Despite normal renal function at presentation, he developed rapidly progressive glomerulonephritis with acute kidney injury due to anti-glomerular basement membrane antibodies (anti-GBM) 4 weeks later. He remained dialysis dependent and died of sepsis 10 months later. We hypothesise that he...

Contrary to group A beta-hemolytic streptococcus as the most common cause of postinfectious glomerulonephritis (PIGN), Epstein-Barr virus (EBV) is only occasionally associated with acute renal involvement. We describe an 11-year-old boy who presented with clinical signs of infective mononucleosis and acute glomerulonephritis characterized by edema, hypertension and dark colored urine with dimin...
