Our study also reports an absence of post-operative, acute renal failure requiring dialysis, neurological complications and sepsis in both groups, including HIV seropositive patients who were not on HAART treatment even though they are at high risk to infections.12 We also found that differences in pre-operative and post-operative CRP levels correlated strongly with duration of mechanical ventilation in the study group. The gene discussed is CRP; the disease is Sepsis.
