Ivermectin treatment showed a slight, non-significant increase in prothrombin ratios in Sierra Leone subjects. No bleeding occurred, suggesting ivermectin has minimal impact on blood coagulation for mass treatment programs.

Area of Science:

  • Pharmacology
  • Hematology
  • Tropical Medicine

Background:

  • Ivermectin is widely used for treating parasitic infections.
  • Concerns exist regarding potential effects of ivermectin on blood coagulation.
  • Understanding ivermectin's impact on coagulation is crucial for public health initiatives.

Purpose of the Study:

  • To assess the effect of ivermectin on prothrombin ratios in subjects from Sierra Leone.
  • To investigate potential interference with vitamin K metabolism and liver function.
  • To evaluate the safety of ivermectin regarding coagulation for mass treatment.

Main Methods:

  • A double-blind, placebo-controlled trial involving 148 subjects.
  • Measurement of prothrombin ratios 13-16 days post-treatment.

  • Investigation of liver function and coagulation factor levels (VII and II).

    • Main Results:

    • Prolonged prothrombin ratios were observed more frequently in the ivermectin group, but the difference was not statistically significant.
    • No bleeding complications were reported in any patients.
    • Reduced levels of coagulation factors VII and II were noted in affected individuals, suggesting potential vitamin K metabolism interference.
    • No abnormalities in liver function tests were detected.

    Conclusions:

    • Ivermectin demonstrates a minimal effect on blood coagulation.
    • Concerns regarding ivermectin's impact on coagulation for mass treatment appear to be unwarranted.
    • Further investigation into vitamin K metabolism may be warranted for specific patient groups.
