Acute glomerulonephritis in Kelantan--a prospective study

Area of Science:

• Pediatric Nephrology
• Infectious Diseases
• Immunology

Background:

• Acute nephritis, specifically acute glomerulonephritis, is a significant pediatric renal disease.
• Understanding the clinical patterns and etiological factors is crucial for effective management in children.
• Socioeconomic factors may influence the incidence and presentation of childhood nephritis.

Purpose of the Study:

• To investigate the clinical presentation and etiological profile of acute glomerulonephritis in Malaysian children.
• To identify common preceding infections and assess the incidence of complications.
• To determine the role of streptococcal infections using immunological markers.

Main Methods:

• Prospective observational study involving 124 children admitted with acute glomerulonephritis.
• Data collection included clinical history, socioeconomic status, preceding infections (skin and throat), and complications.
• Immunological investigations included Anti-Streptolysin O Titer (ASOT), anti-DNase B, and complement C3 levels.

Main Results:

• The majority of patients (121/124) were diagnosed with post-streptococcal nephritis, predominantly following skin infections.
• High rates of complications were observed, including severe hypertension (43.6%), pulmonary edema (36.3%), and severe azotemia (10.5%).
• A significant proportion of families belonged to lower socioeconomic groups, with 54% below the poverty line.

Conclusions:

• Post-streptococcal glomerulonephritis is the primary cause of acute nephritis in this pediatric cohort, often linked to preceding skin infections.
• The study highlights a high burden of severe complications, emphasizing the need for prompt diagnosis and management.
• Lower socioeconomic status appears to be a contributing factor, suggesting a need for targeted public health interventions.
