Brief Summary:

Randomized Controlled Trial:

The investigational materials used in this trial were administered to subjects each day by trained clinicians.

Primary Objectives:

  • assess the effect of dietary supplementation with arachidonic acid on the cure rates for Schistosomiasis mansoni with and without concomitant treatment with praziquantel.
  • assess the safety of dietary supplementation using arachidonic acid in children with clinically confirmed schistosomiasis mansoni infection.

Secondary objective:

  • to measure changes in total phospholipids in plasma.

Condition or disease Intervention/treatment Phase
Schistosomiasis Bilharzia Drug: Praziquantel (PZQ) Dietary Supplement: Arachidonic acid (ARA) Dietary Supplement: PZQ+ARA Not Applicable

Arm Intervention/treatment
Active Comparator: Praziquantel (PZQ)
A single dose of praziquantel (40 mg/kg) was administered orally on day-1 only, and after 7 days, 1 g of corn oil/soybean oil (50%/50%), for 15 consecutive days of school.
Drug: Praziquantel (PZQ)

40 mg/kg, a single dose, administered orally

1 g of corn/soybean oil (50%/50%), administered orally

Other Names:
  • Praziquantel (generic)
  • Biltricide
  • trematodicide

Experimental: Arachidonic acid (ARA)
A single daily dose of 1 g microbial arachidonic acid-rich oil administered orally for 15 consecutive days of school.
Dietary Supplement: Arachidonic acid (ARA)
ARA (40% of total fatty acid)
Other Names:
  • Microbial arachidonic acid-rich oil

Experimental: PZQ + ARA
A single dose of PZQ (40 mg/kg) was administered orally on day-1 only, and after 7 days, followed the next day by 1 g of microbial ARA-rich oil, administered orally as a single dose on 15 consecutive days of school.
Dietary Supplement: PZQ+ARA
A single dose of PZQ administered seven days in advance of initial treatment with ARA.
Other Names:
  • praziquantel

Primary Outcome Measures :
  1. Percent egg reduction [ Time Frame: 4 weeks after end of 1 day PZQ treatment ]
    Stool samples were collected from each child on three consecutive days to determine egg counts per gram of stool.

Secondary Outcome Measures :
  1. Biochemical and hematological parameters [ Time Frame: Three days after a 15-day ARA supplementation ]
    Blood samples were collected using 4 vacutainer tubes. Serum was used to measure enzyme markers of liver and kidney functions. Coagulation tests included prothrombin- and activated thromboplastin times were measured using citrated blood. Complete hematological profiles were obtained using EDTA-anticoagulated blood samples.

  2. Total plasma phospholipids [ Time Frame: Three days after 15-day ARA supplementation. ]
    Blood samples (10 ml) were collected 2-3 days before the start of treatment, and 3 days after completion of treatment with ARA or PZQ+ARA for analysis of the phospholipids in plasma.
