At completion of the scholarly study, all participants were examined by us for HIV infection, using an enzyme-connected immunosorbent assay . Particular laboratory assessments are shown in Table S1 in the Supplementary Appendix. For participants with indeterminate or excellent results on HIV testing of oral transudate, we performed dual, parallel, fingerstick rapid HIV assessment and provided counseling . Furthermore, we obtained blood samples to test for HIV an infection by means of ELISA and to gauge the baseline viral load and CD4+ lymphocyte count; we also tested for antiretroviral resistance mutations, using standard and ultrasensitive techniques.These data support the ongoing Phase 3 development system for daclatasvir and further studies of daclatasvir as a component of DAA-centered HCV treatment regimens. A characterization of ALT flares seen in hepatitis B treatment with the investigational interferon Lambda vs. Alfa interferon, reflecting differing profiles for both compounds. Lambda is being developed as a potential option for alfa wherever interferon is used in the treatment of either HCV or HBV. An analysis of sustained virologic response with daclatasvir plus sofosbuvir, with or without ribavirin, in sufferers with HCV genotype 1 who failed telaprevir or boceprevir previously.
