title: Comorbidities and their impact on mortality in HCV and HCV-HIV-coinfected persons on dialysis.
abstract: OBJECTIVE
  To determine the rates of non-human immuno deficiency virus (HIV)-related comorbidities and their impact on survival in hepatitis C virus (HCV) and HCV-HIV coinfected persons on dialysis.
  
  
  METHODS
  We identified HCV-infected subjects and diagnoses of medical and psychiatric comorbidities in the United States Renal Data System using ICD-9 codes. Logistic regression was used to determine the odds of comorbidities and predictors of mortality.
  
  
  RESULTS
  We identified 5310 HCV-infected and 427 HCVHIV-coinfected subjects. The latter were younger, more likely to be male, black race, and had a lower body mass index. After adjusting for age, race, and sex we found that coronary artery disease (CAD), diabetes mellitus (DM) as primary cause of renal failure and cirrhosis were less frequently diagnosed in the HCVHIV-coinfected subjects, whereas hepatitis B, wasting, drug and alcohol abuse, and dependence were more frequently diagnosed.Increasing age, CAD, stroke, DM, cirrhosis, wasting, cancer,and drug abuse and dependence were associated with higher odds of death in the HCV monoinfected subjects, whereas cirrhosis, wasting, and smoking were the only such factors in the HCV-HIV-coinfected subjects.
  
  
  CONCLUSIONS
  The frequency and patterns of comorbidities and predictors of death differ in HCV-monoinfected and HCVHIV-coinfected persons on dialysis. These differences should be taken into account when designing future interventions.
