Chronic liver disease in black children in Durban, South Africa
Insights
Chronic liver disease in South African children is commonly caused by infections like Hepatitis B (HBsAg) and Schistosoma mansoni, unlike in developed nations. Many cases are preventable, highlighting a key difference in etiology.
Area of Science:
- Hepatology
- Pediatrics
- Infectious Diseases
Background:
- Chronic liver disease (CLD) etiology varies significantly between developed and developing countries.
- Previous research on pediatric CLD predominantly reflects causes found in industrialized nations.
Purpose of the Study:
- To investigate the specific causes and clinical presentation of chronic liver disease in South African black children.
- To compare the etiological profile of pediatric CLD in this population with that reported globally.
Main Methods:
- Prospective study involving 130 South African black children diagnosed with chronic liver disease.
- Analysis of etiological factors, including infectious, inherited, autoimmune, iatrogenic, and cryptogenic disorders.
Main Results:
- Hepatitis B surface antigen (HBsAg) and Schistosoma mansoni infestation were the most frequent causes of CLD.
- HBsAg was associated with cirrhosis and chronic active hepatitis; Schistosoma mansoni affected 41 children.
- Inherited, autoimmune, iatrogenic, and cryptogenic disorders were less prevalent compared to developed countries.
Conclusions:
- Infectious agents are the primary drivers of chronic liver disease in this pediatric cohort from a developing region.
- The high prevalence of infection-related CLD suggests potential for widespread prevention strategies in similar settings.
- The majority of children presented with asymptomatic, compensated liver disease, differing from some developed country reports.
Abstract:
In a prospective study of 130 South African black children with chronic liver disease, it was found that the aetiology differed from that reported from developed countries. The most common cause of chronic liver disease (CLD) was HBsAg (33 of 55 with cirrhosis and 24 of 28 with chronic active hepatitis) and Schistosoma mansoni infestation (41 children). Inherited, auto-immune, iatrogenic and cryptogenic disorders, which are the usual causes in the developed world, were less common. The majority of children seen in this series were in an asymptomatic compensated state in contrast to reports from some developed countries. It is concluded that because infection is a common cause of CLD in the Third World it may be preventable in many cases.
