Overview on Acute Poststreptococcal Glomerulonephritis in Pediatrics: A Review
Journal of Pharmaceutical Research International, 2021
Acute poststreptococcal glomerulonephritis (APSGN) is the most common kind of post-infectious glomerulonephritis and is caused by group A streptococcus (Streptococcus pyogenes). Although the prevalence of PSGN has decreased in affluent nations, non-streptococcal species are becoming more common. and it is still the major cause of glomerulonephritis in children. APSGN can manifest itself in epidemic outbreaks or clusters of instances, as well as in single persons. Epidemic outbreaks have previously been documented as a result of upper respiratory or cutaneous streptococcal infections in various parts of the world. In developed nations, APSGN is now mostly a disease of the elderly, who are more likely to have disabling illnesses such as cancer, alcoholism, or diabetes. Children between the ages of 3 and 12 (with a peak incidence between the ages of 5 and 6 years) and seniors over the age of 60 are the most commonly affected. The pathophysiology of APSGN is complicated by inflammation....

BACKGROUND The incidence of post-infectious glomerulonephritis (PIGN) has decreased over the last decades. As a result, recent epidemiological data from industrialized countries are scarce. OBJECTIVES To evaluate patterns of PIGN in children and detect possible predictors of disease severity. METHODS We collected clinical and laboratory data of patients with PIGN admitted to Schneider Children's Medical Center during 1994-2011. Diagnostic criteria included presence of hematuria with/without other features of nephritic syndrome along with hypocomplementemia and/or microbiological/serological evidence of streptococcal infection. Patients with other diseases (systemic lupus erythematosus, vasculitis, etc.) were excluded from the study. RESULTS A total of 125 patients with a mean age of 5.8 ± 3.3 years (range 1.5-17.6), of whom 16% were < 3 years, matched the study criteria. Presenting features included hypertension in 103 (82.4%) patients, azotemia in 87 (70.2%), fever in 49 (40...
Protracted Clinical Course of Postinfectious Glomerulonephritis in a Previously Healthy Child
Case reports in nephrology and dialysis
Acute postinfectious glomerulonephritis (PIGN) affects children typically after upper respiratory tract or skin infections with streptococci but can complicate the course of other infections. In children, it is generally a self-limiting disease with excellent prognosis. This paper reports a previously healthy 4-year-old boy who experienced a protracted course of PIGN with persisting episodes of gross haematuria, proteinuria, decreased complement C3c levels but normal P-creatinine levels. Due to the protracted course and the nephrotic-range proteinuria, a renal biopsy was performed 6 months after the initial presentation and the overall pathology was consistent with acute endocapillary glomerulonephritis.
Clinical Presentations and Outcome of Acute Glomerulonephritis in Children

The majority of children with the epidemic form of acute post-streptococcal glomerulonephritis (APSGN) have an excellent prognosis, which contrasts with the poor long-term outcome of sporadic cases. Therapy is largely supportive. Rarely, the disease shows long-term complications, worsening to chronic kidney disease requiring long-term interventional measures. To compare the effectiveness of different therapeutic strategies for the prevention and treatment of APSGN in childhood, the authors reviewed randomized controlled trials on the prevention and treatment of APSGN in children. Nine studies fit the inclusion criteria. Primary outcomes were the development of APSGN, the effectiveness of medication for controlling hypertension, and the development of chronic renal failure in patients with crescentic glomerulonephritis. No advantages of antimicrobials (cefuroxim, ceftibuten, and others) given for 5 days were found over penicillin V given for 10 days (4 trials). Nifedipine showed adva...
Prognostic factors for mortality in pediatric acute poststreptococcal glomerulonephritis
Paediatrica Indonesiana, 2016
Background Acute post-streptococcal glomerulonephritis (APSGN) is one of the most common causes of glomerular disease in developing countries, including Indonesia. It can lead to end stage renal failure and higher mortality rates. To decrease morbidity and mortality, it is important to understand the prognostic factors affecting the disease.Objective To identify prognostic factors affecting outcomes in pediatric APSGN patients.Methods Study data were collected from medical records of patients with APSGN hospitalized in Wahidin Sudirohusodo Hospital, Makassar in 2009-2013. Possible prognotic factors analyzed were gender, age, nutritional status, level of consciousness, as well as proteinuria, hemoglobin, serum albumin, urea, and creatinine levels.Results Of 86 subjects, 82 (95.3%) survived and 4 (4.7%) died. Fifty-three (61.6%) patients were male and 33 (38.4%) were female. Subjects’ ages ranged from 3.42 to 14.67 years, with a mean age of 9.36 years. Multivariate analysis revealed s...
Acute Post-Streptococcal Glomerulonephritis in Children A Review
Bangladesh Journal of Child Health, 2014
Acute poststreptococcal glomerulonephritis (APSGN) is characterized by abrupt onset of hematuria, edema, hypertension, oliguria and impaired renal function following streptococcal group A â hemolytic streptococcal throat and skin infection. There is a declining incidence of APSGN worldwide, particularly in industrialized nations because of easier and earlier access to competent medical treatment of streptococcal infections and the widespread use of fluorination of water since virulence factors in streptococcus pyogens are reduced with fluoride exposure. But in the underdeveloped world, global burden of APSGN continues to be significant with lower estimate of 9.3 to 9.8 cases per 1,00,000 population per year to higher estimates as high as three times these values. Furthermore, clusters of cases are more frequently reported in poor communities in industrialized countries while epidemics of more than 100 cases are reported in the middle ranger countries with mean annual health expenditure per capita of about 550 US dollars. APSGN typically follows 1to2 weeks after pharyngeal infection and 2 to 4 weeks after skin infection by nephritogenic strains of group A â hemolytic streptococcus in a range of 5-15 years of age. Subclinical cases are 4-10 times higher than symptomatic patients. The acute phase generally resolves within 4-8 weeks but microscopic hematuria may persist for 1-2 yr after the initial presentation. Acute complications of symptomatic patients are hypertensive heart failure, encephalopathy and retinopathy. There can be acute renal failure and rarely rapidly progressive (crescentic) glomerulonephritis, hyperkalemia, hyperphosphatemia, hypocalcemia and acidosis.

Objectives To evaluate the clinical characteristics, complications and outcome of post-infectious glomerulonephritis (PIGN). Methods This prospective observational study was conducted from January 2013 through July 2014 at a tertiary care hospital in south India. Post-streptococcal glomerulonephritis (PSGN) was diagnosed in the presence of: a) Hematuria and proteinuria b) Clinico-serological evidence of recent streptococcal infection [recent pyodermas or pharyngitis; positive antistreptolysin-O (ASO) titres, anti-DNAse B titres or throat swab positivity for Group A streptococcus], and c) Low serum C3 levels, with normalization on 8 wk follow up. PIGN included PSGN and other infectious etiologies. AKI was classified as per Acute Kidney Injury Network (AKIN) criteria. Clinical features, biochemical and serological investigations in the study subjects were recorded. Results Among 83 children with acute nephritic syndrome (ANS) recruited, 72 (86.7 %) had PIGN. PSGN was the most common etiology [65(90.3 %)] among the PIGN cases. Pyodermas, upper respiratory infections and varicella preceded hematuria in 58 (80.6 %)
Outcome of severe acute post-streptococcal glomerulonephritis in New Zealand children
Pediatric Nephrology, 2008
Post-streptococcal glomerulonephritis (PSGN) is the commonest cause of severe acute glomerulonephritis in New Zealand children, with the majority (85%) of the patients being of either Pacific Island or Maori ethnicity. We have performed a retrospective study on 27 pediatric patients with acute PSGN. Of these patients, those with crescentic glomerulonephritis (n=11) had a greater tendency (72.7%) for needing acute dialysis and were left with persistent urinary sediment abnormalities after a mean follow-up of 3.2 years (95% confidence interval 2.1-4.3). The efficacy of immunosuppression in the group with crescentic disease was uncertain. The severity of renal histopathological abnormalities as judged by the total biopsy score did not correlate with either presentation or eventual outcome. Severe childhood acute post-streptococcal glomerulonephritis, although uncommon, results in significant long-term renal morbidity, particularly among Maori and Pacific Island children.
A Cluster of Cases of Acute Poststreptococcal Glomerulonephritis in a Family
Chattagram Maa-O-Shishu Hospital Medical College Journal, 2014
Acute post streptococcal glomerulonephritis (APSGN) remains a common cause of acute nephritis in children. Acute poststreptococcal glomerulonephritis usually occurs as sporadic cases, occasionally an unusually high incidence of acute nephritis has been recorded. In our country we need to recognize, document and analyze epidemic attacks of acute post streptococcal glomerulonephritis. Then we can plan for its prevention. We have reported here a cluster of cases of APSGN prevailed in a family of a rural setting of southeast part of Bangladesh which was admitted in a subdistrict level hospital and also noticed that total admitted cases of APSGN in that hospital was more during the month of notification in comparison to other months but were not able to identify all the cases of APSGN prevailing in that area. Prophylactic antibiotic treatment is advisable in epidemic conditions and to household contacts of index cases in communities where the prevalence of the disease is high. It is ex...
