This study compared the pattern of acute glomerulonephritis (AGN), a disease known to be influenced by socioeconomic and environmental factors, in children 12 years and under, for the years 1971 and 1985. All children admitted to the four major paediatric departments with haematuria and at least two of the following (oedema, hypertension or oliguria) had an initial diagnosis of AGN. A sample population from one unit from 1980 to 1984 showed that over 70% of these children had evidence of a post-streptococcal aetiology. In 1971, 411 children were admitted with AGN, as compared with only 58 in 1985. The age-sex-race standardized rates for 1971 and 1985 were 0.632 and 0.023/1,000 children 12 years and under, respectively (P less than 0.001). The mean age of presentation was lower in 1971. Over this period, Singapore saw a threefold rise in the gross national product, accompanied by rapid urbanization. On analysis of the housing pattern, only 31% of the children lived in high-rise apartments in 1971, in contrast with 86% in 1985 (P less than 0.001). The majority of non-apartment dwellers had homes in rural districts. From an epidemiological perspective, factors which could have led to the highly significant decline in prevalence of AGN in Singapore children included improvement in the socioeconomic status and health care system, and urbanization of the country.

This prospective study involved 102 patients who had acute renal failure and were treated at Aleppo University Hospital during the period 1980-1986. Acute renal failure in this group was categorized, according to the aetiology, into 12 causes. Obstructive uropathy, surgery, and crush injuries constituted 64% of all cases in males. In females, 56% of all cases were due to obstetrical trauma, acute glomerulonephritis and eclampsia. Haemodialysis was used for the treatment of 77 patients, with 65% cure, and 33% mortality. Conservative treatment was adopted for 21 patients with 62% cure, and 38% mortality. Four patients were treated by peritoneal dialysis, and they all survived. The prognosis in the studied group depended on the aetiology of acute renal failure, and accompanying risk factors such as infection, electrolyte disturbances, encephalopathy, failure of other end organs, etc. It was also found that patients presenting with anuria or oliguria had worse prognosis when compared with patients who had normal urine output.

Twenty-seven adults with acute poststreptococcal glomerulonephritis were divided into two groups according to the severity of reduction in renal function: (1) 14 patients with mild depression of renal function, and (2) 13 patients with more severe renal insufficiency. In the first group the outcome was favourable, with complete clinical recovery in 11 patients. Only two patients in the second group have recovered. Five have died of renal failure and in six the chronic stage has developed. The most notable histopathological lesion observed in this group of patients was severe proliferative glomerulonephritis with a large number of epithelial crescents. According to the mode of development and time of onset of renal failure, these 13 patients could be divided into three sub-groups: (1) early renal failure without oliguria (three patients), (2) early renal failure with severe oliguria or anuria (three patients) and (3) delayed renal failure (seven patients).Although there are exceptions, the development of renal insufficiency in an adult patient suffering from acute glomerulonephritis is usually associated with a guarded prognosis.

A four-year-old boy developed oliguria, proteinuria and hypocomplementemia, without hematuria, in the course of proven infectious mononucleosis. A chest radiograph revealed a mild cardiomegaly, prominent pulmonary vasculature and pleural fluid. These abnormalities were compatible with acute glomerulonephritis and were in support of this clinical diagnosis in spite of the absence of hematuria.

Fifty two children (upto 12 years age) with acute renal failure (ARF) admitted to the Nephrology services between January, 1989 to August, 1992 were studied to determine the cause and outcome. Of these, 39 were boys and 13 girls; 27 (51.9%) patients were below 4 years of age. Hemolytic uremic syndrome (HUS) was the commonest cause of ARF (30.8%) followed by acute tubular necrosis (ATN) in 28.84% and acute glomerulonephritis in 19.23%. All patients had severe renal involvement with anuria in 53.6% and oliguria in 46.4% at presentation. HUS was the leading cause of anuria (53.6%), followed by obstructive uropathy (21.4%). Thirty five patients required dialytic support for a median duration of 18 days (2-90 days). The mortality was 34.6%. Seven patients of HUS, 4 patients of ARF following surgery, 3 patients each of ATN and glomerulonephritis and one patient of obstructive uropathy died. Anuria at onset, central nervous system or respiratory complications and delay in institution of dialytic support were bad prognostic factors. We conclude that early referral and prompt institution of dialytic support may be helpful in decreasing the mortality.

Acute glomerulonephritis is a distinct clinical entity, more frequently found in younger age. We report 69 patients with AcGN (25 female and 44 male) mean age 26 years (range 15-58). The disease is clinically characterized with hypertension (57%), edema (59%) and oliguria (35%). Urine analysis showed microhaematuria/proteinuria (36%) and micro/macrohaematuria alone in 89%, while azothaemia was observed in 16% pts, and decreased serum complement levels in one third of patients, more often decrease of C3 (33%) than C4 (15%). Initial infection of the upper respiratory tract was seen in 65%, pneumonia in 8%. In 25% of pts. there were no data of previous infection. Cultures of pharyngeal smear revealed. Streptococcus only in 2 pts. Elevated AST titer was found in 32% pts. Eleven kidney biopsies were made, and histological examination showed 2 normal findings, 6 mesangioproliferative GH, 2 endocapillary GN and 1 membranoproliferative GN. Follow ups have showed urinary abnormalities in 25% of pts., without developing renal failure.

A full-term neonate with a history of umbilical venous catheterization followed by coagulase-negative staphylococcal sepsis is presented. The infant developed a solitary hepatic abscess with saprophytic organisms. Her liver abscess resulted in acute glomerulonephritis characterized by hypertension, proteinuria, oliguria, and azotemia. Surgical drainage and antibiotic treatment of the abscess was associated with resolution of the glomerulonephritis. Glomerulonephritis due to solitary liver abscess in a neonate has not been reported previously. Acute onset of glomerulonephritis should prompt a search for occult sources of infection.

Post-infectious acute glomerulonephritis with hypertensive encephalopathy is characterized by episodic hypertension with headache, vomiting, and hematuria. The association between hypertensive encephalopathy and cortical blindness in children with acute glomerulonephritis is extremely rare. We report the case of a 10-year-old boy with acute glomerulonephritis who presented with gross hematuria, headache, vomiting, and oliguria, and developed transient cortical blindness as a complication of hypertensive encephalopathy. No occurrence of seizure was observed during the clinical course. T2-weighted cranial magnetic resonance imaging showed a high-intensity signal over cortical and subcortical areas of bilateral occipital regions. His vision recovered fully, 2 days after receiving antihypertensive therapy. The patient was well without complaint at 1-year follow-up. This case highlights the possibility that cortical blindness may develop as a complication of acute glomerulonephritis in children. Prevention of the occurrence of neurological deficits in children with acute glomerulonephritis and hypertensive encephalopathy requires careful evaluation and appropriate management of hypertension.

In children post-infectious acute glomerulonephritis is usually caused by beta-hemolytic streptococcus and has a fair prognosis with spontaneous remission in most cases. Rarely, however, the disease may be complicated by oliguria and/or severe hypertension which can cause cardiac congestion or cerebral edema. In adults the acute glomerulonephritis may be caused by a number of different micro-organisms and it often develops in patients with other diseases. The prognosis may be severe and is worsening over the years. The risk of chronic renal failure is increased in patients with crescents and with large interstitial infiltrates. A renal biopsy is recommended in adults with acute glomerulonephritis to make possible a differential diagnosis with other diseases presenting with a nephritic syndrome, to assess the prognosis and to evaluate the pro's and the con's of a treatment with steroid and/or immunosuppressive agents.

Nineteen adults who had acute glomerulonephritis were reviewed with respect to the clinical course and long-term follow-up. The age range was from 17 to 55 years. Only one patient died during the acute episode. In 11 cases, onset occurred between November and January and 15 of the patients had a known respiratory tract infection three to 30 days before the onset. The most important symptoms noted were weight gain, edema, dyspnea, oliguria and red or smoky urine. The most prominent physical signs were elevated blood pressure, edema, abnormalities in the chest and fever of over 100 degrees F. Fifteen patients showed roentgen evidence of pulmonary vascular congestion, pleural effusion, cardiomegaly, pneumonia or a combination of these abnormalities. All the patients had proteinuria and red blood cells in the urine, and half of them had red blood cell casts. Azotemia, when present, subsided in 9.4 days. The average diastolic pressure was 105 mm. of mercury and the mean fall was 26 mm. in 23.5 days. At six months, nine of the 13 patients still being observed continued to show proteinuria or microscopic hematuria (seven showed both). A late follow-up of ten patients showed one to have significant hypertension and one to have early functional impairment and inconstant proteinuria. In these cases the average blood pressure was 140/91 mm. as compared with 119/74 mm. at the time of discharge. Sporadic glomerulonephritis in adults presents essentially the same pattern as it does in children. Urinary abnormalities may persist for months or even years, and neither the present series nor those reported by others clearly reveal the ultimate prognosis.
