Assessment of risk factors in pyogenic liver abscesses in children

Area of Science:

• Pediatric Gastroenterology
• Hepatology
• Infectious Diseases

Background:

• Pyogenic liver abscess (LA) is a significant cause of illness and death in developing nations, particularly India.
• Risk factors for pediatric LA, especially in children without other illnesses, are not well understood.
• Previous studies have yielded inconclusive results regarding the causes of LA in children.

Purpose of the Study:

• To identify risk factors associated with pyogenic liver abscess (LA) in children in India.
• To evaluate the outcomes of different management strategies for pediatric LA.
• To investigate the role of socioeconomic status and immunodeficiency in pediatric LA.

Main Methods:

• Prospective observational study conducted at a tertiary teaching hospital in New Delhi, India.
• Inclusion of 52 children aged 2 months to 12 years with sonographically confirmed LA.
• Management involved intravenous antibiotics, investigations, and interventions such as needle aspiration or pigtail catheter drainage.

Main Results:

• The mean age of patients was 6 years and 4 months, with a male:female ratio of 1.4:1. Approximately 50% of children were malnourished.
• Fever, abdominal pain, and loss of appetite were the most common symptoms. Poor socioeconomic status and anemia were identified as significant associated risk factors.
• Selective immunoglobulin A (IgA) deficiency was the most common primary immunodeficiency, followed by T-cell defects. Clinical jaundice, elevated GGT, and impending rupture correlated with time to defervescence.

Conclusions:

• Poor socioeconomic status leading to malnutrition is a significant risk factor for pediatric LA.
• Selective IgA deficiency was the most frequent immunodeficiency observed in affected children.
• Conservative management, including aspiration and percutaneous drainage, resulted in reduced mortality and favorable recovery rates.
