Group A beta-hemolytic streptococcus can cause several postinfectious, nonsuppurative immune- mediated diseases including acute rheumatic fever, poststreptococcal reactive arthritis, pediatric autoimmune neuropsychiatric disorders, and poststreptococcal glomerulonephritis. Except for sporadic outbreaks, poststreptococcal autoimmune syndromes occur most commonly in sub-Saharan Africa, India, Australia, and New Zealand. Children younger than three years are rarely affected by group A streptococcus pharyngitis or rheumatic fever, and usually do not require testing. Read More

We present a case of acute post-streptococcal glomerulonephritis (APSGN) with autoimmune hemolytic anemia (AIHA). Along with the classic findings of APSGN, the patient had a positive direct antiglobulin test and an anticardiolipin antibody without any typical clinical manifestations of antiphospholipid syndrome (APS). This case raises questions of the relationship between Streptococcus and the development of autoimmune hemolytic anemia in children. Read More

This report summarizes a case of a 4-year-old girl with poststreptococcal glomerulonephritis and diffuse alveolar hemorrhage, an atypical presentation in this age group and type of vasculitic disease. We propose that her rapid improvement in clinical status was due to her treatment, continuous renal replacement therapy (CRRT). This mechanism would have impacted recovery by removing factors such as endothelial microparticles, superantigens, and immune complexes that have been postulated as the pulmonary-renal link.

Background: Posterior reversible encephalopathy syndrome is a neurotoxic condition that occurs as a result of the failure of posterior circulatory autoregulation in response to acute changes in blood pressure. Overperfusion with resultant disruption of the blood-brain barrier results in vasogenic edema, but not infarction. Posterior reversible encephalopathy syndrome can be the presenting feature of postinfectious glomerulonephritis, which has been reported in approximately 5% of hospitalized children, and it has been reported in very few cases of adult patients with sickle cell anemia.

Infection-related glomerulonephritis (IRGN) is an immune-mediated glomerulo-nephritis, most commonly caused by bacterial infections. Although there is an increased incidence of infectious episodes in renal transplant recipients, IRGN as a cause of de novo glomerulonephritis is rarely seen probably due to impaired immunity. We hereby report a 28-year-old male renal transplant recipient, who developed IRGN following impetigenous skin lesions after six years of transplant. Read More

Streptococcus pyogenes, the Group A Streptococcus (GAS), is the most common cause of bacterial pharyngitis in children and adults. Innate and adaptive host immune responses are fundamental for defense against streptococcal pharyngitis and are central to the clinical manifestation of disease. Host immune responses also contribute to the severe poststreptococcal immune diseases that constitute the major disease burden for this organism. Read More

Retropharyngeal abscess is an infection involving the retropharyngeal space which is posterior to the pharynx and oesophagus, and it results as a complication of a primary infection elsewhere in the head and neck including the nasopharynx, paranasal sinuses, or middle ear, which drain lymph to the retropharyngeal lymph nodes. Their lymph nodes are prominent in children and atrophy with age. Therefore, retropharyngeal abscess is most frequently encountered in children, with 75% of cases occurring before the age of 5 years, and often in the first year of life. Read More

Acute poststreptococcal glomerulonephritis (APSGN) is a well-established disease. Although various immune responses are thought to be involved in the pathogenesis of APSGN, the disease has a self-limiting nature in clinical practice, despite the presence of severe acute symptoms. We herein report the case of a 78-year-old woman with APSGN who developed primary biliary cirrhosis (PBC) after achieving remission of renal manifestations, including anasarca and elevation of serum creatinine, indicating that persistent alterations in the immune system can cause extrarenal disorders.

Background: Streptococcus pyogenes is responsible for 5-15% and 20-30% of acute pharyngitis/tonsillitis in adults and children, respectively. It not only causes acute illness but also can give rise to local suppurative complications such as peritonsillar abscess as well as trigger the postinfectious syndromes of glomerulonephritis, acute rheumatic fever and poststreptococcal reactive arthritis. Here, we report a case of a young healthy adult in whom both peritonsillar abscess and poststreptococcal reactive arthritis developed as a complication of acute streptococcal tonsillitis. Read More

In addition to being the main cause of glomerulonephritis in children, poststreptococcal glomerulonephritis (PSGN) has recently been shown in older patients, especially those with malignancy or diabetes mellitus. The pathogenesis of PSGN has been ascribed to activation of complement 3 (C3) of the alternative complement cascade which, along with immunoglobulin (Ig) G and IgM deposits, is observed in renal tissue. Our aim here is to discuss the probable causes of PSGN developing with isolated IgM deposition in a 52-year-old patient with essential thrombocytosis followed-up over the previous 3. Read More

Postinfectious glomerulonephritis is an immune-mediated disease occurring as a result of the host response to an extrarenal infection. The classical form of poststreptococcal disease is decreasing worldwide but remains a significant health care problem in developing countries, especially in children. In industrialised countries postinfectious glomerulonephritis is now primarily due to non-streptococcal disease. Read More

On the basis of strong research evidence, the prevalence of poststreptococcal glomerulonephritis (PSGN) is decreasing worldwide, although it still remains the leading cause of glomerulonephritis in children. The overall decrease in prevalence of PSGN has been mainly driven by a significant decrease in pyoderma seen in the last half-century, such that postpharyngitic PSGN is most commonly seen in developed nations. On the basis of primarily consensus because of a lack of relevant clinical studies, the latency period between streptococcal infection and the development of nephritis is a hallmark of PSGN, with this period lasting 1 to 2 weeks with pharyngeal infections or 2 to 6 weeks with skin infections.

Streptococcus pyogenes, also known as group A Streptococcus (GAS), causes mild human infections such as pharyngitis and impetigo and serious infections such as necrotizing fasciitis and streptococcal toxic shock syndrome. Furthermore, repeated GAS infections may trigger autoimmune diseases, including acute poststreptococcal glomerulonephritis, acute rheumatic fever, and rheumatic heart disease. Combined, these diseases account for over half a million deaths per year globally. Read More
