Overview

Case-control study examines HTLV-1 prevalence and genetic factors in Iraqi brain tumor patients, suggesting risk markers.

Key Points

  • The study aimed to assess HTLV-1 infection and genetic polymorphisms in Iraqi brain tumor patients compared to controls.
  • Case-control study involving 100 brain tissue samples (75 tumors, 25 controls) from January to September 2022.
  • Tissue samples stored at -80°C for RNA extraction and analyzed using quantitative real-time PCR and conventional PCR.
  • Evaluation of TNF-α, KIR, and IL-1Ra gene polymorphisms in brain tumor patients and control groups.
  • 66.7% of brain tumor specimens had HTLV-1 viral infection, with a 42% infection rate (21 of 50).
  • Gene polymorphisms in TNF-α and KIR associated with increased risk, showing significant differences (P < 0.05) compared to controls.
  • IL-1Ra gene polymorphism did not show significant differences for certain variants.
