  4. Background Race has been shown to be a factor in the prevalence and the response to therapy for hepatitis C virus (HCV) infection 2.1% Mexican Americans vs 1.5% non-Hispanic white NEngl J Med1999 Latinos and other ethnic subpopulations have been underrepresented in clinical trials

  5. Am J Med. 2004 Differences in treatment outcome for hepatitis C among ethnic groups. A total of 661 patients. Sustained virologic response was highest among Asians (61% [22/36]), followed by whites (39% [193/496]), Hispanics (23% [18/79]), and African Americans (14% • P R Health Sci J. 2004 Response to combination therapy of interferon alfa-2b plus ribavirin in Hispanics with chronic hepatitis C.Hispanic patients had a low response rate to combination therapy

  6. Prospective multicentric (52 centers) non randomized • INCLUSION CRITERIA: • Latino: spanish speaking countries I (south and central America, mexico and carabbean) • HCV RNA >10 IU/ml • High LFT • Compensated LD ( CHILD PUGH <6) • CIRRHOSIS 10% IN BOTH GROUP • EXCLUSION CRITERIA: • Hb <12 female < 13 male • WBC <11.5 10 9 plt <100 000 • Drug abuse last 12 months or all other liver diseases hepA,B,HIV • Severe psychiatric D/O • Clinically significant cardiac, renal, seizure and retinopathy

  7. I OUTCOME: Sustained virologic response defined as undetectable HCV RNA level (<28IU/ml) 24 weeks after the end of treatment period (week 72) • II OUTCOME: VR during all the treatment period • Rapid virologic responses (undetectable HCV RNA at week 4) • Complete early virologic response(undetectable HCV RNA at week 12) • Virologic response at week 24 • Virologic response at week 48 • Relapse between 48 & 72 weeks

  8. Methods

  9. Conclusions • Latino with HCV I have lower response to standard therapy with peginterferon and ribavirin vs non latino • Baseline viral load predictive of SVR as previous studies • Low ALT predicted of better response in latino; the opposite for non-latino • BMI not related to SVR
