Factors affecting C3 in intestinal schistosomiasis

Area of Science:

• Immunology
• Hepatology
• Parasitology

Background:

• Schistosomiasis is a parasitic disease affecting millions worldwide.
• Complement component C3 (C3) plays a crucial role in immune responses.
• Hepatitis B virus (HBV) infection is common in schistosomiasis-endemic areas.

Purpose of the Study:

• To investigate complement component C3 (C3) levels in patients with schistosomiasis.
• To explore the relationship between C3 levels, Schistosoma mansoni (S. mansoni) egg count, Hepatitis B surface antigen (HBsAg) presence, and liver function.

Main Methods:

• Serum C3 levels were measured in schistosomal patients without obvious nephritis.
• C3 levels were analyzed in relation to S. mansoni egg count, HBsAg status, and liver function tests.
• Statistical analysis was performed to determine correlations and significant differences.

Main Results:

• C3 levels were significantly lower in schistosomal patients compared to normal individuals.
• C3 levels were low in both HBsAg-negative and HBsAg-positive patients.
• No significant difference in C3 levels was observed based on HBsAg status or S. mansoni egg count (categorized as >400 or <400 eggs/1g).
• Ascites presence did not affect C3 concentration.
• A positive correlation was found between C3 and serum albumin levels.

Conclusions:

• Complement component C3 (C3) levels are reduced in patients with schistosomiasis, irrespective of HBsAg status or S. mansoni egg burden.
• Serum albumin may influence C3 levels in schistosomal patients.
• Further research is needed to understand the implications of C3 dysregulation in schistosomiasis and its impact on liver function.
