RESUMO

BACKGROUND: Persons involved with the justice system have an elevated risk of hepatitis C virus (HCV) yet remain marginalized from treatment. Efforts to eliminate HCV will require targeted interventions within the justice system effective at providing diagnosis and treatment. METHODS: We implemented a novel HCV screening and treatment intervention for persons under community supervision in Rhode Island, USA during April 2018--March 2020. Participants received rapid point-of-care HCV antibody testing onsite and referral to community laboratory and treatment services as indicated. We assessed the HCV care cascade to identify areas for improvement. RESULTS: Overall, 483 individuals were screened for HCV antibody; 85 (18%) were positive. A minority of participants with positive HCV antibody tests (n=25/85, 29%) presented to community laboratories for confirmatory testing. Among participants that received HCV viral load results and linked to a treatment provider (n=12), four initiated treatment, three had record of completing treatment, and two were confirmed to have achieved cure. CONCLUSION: Linkage to HCV viral load testing and treatment was challenging in this community supervision population, with substantial loss to follow-up at each step of the HCV cascade. Community supervision remains an important venue for case identification but substantial barriers to accessing HCV treatment exist. Innovative HCV diagnosis and treatment strategies are needed for community supervision populations.

RESUMO

Biospecimen quality can vary depending on many pre- and post-collection variables. In this study, we consider a natural disaster as a post-collection variable that may have compromised the quality of frozen tissue specimens. To investigate this possible link, we compared the quality of nucleic acids, the level of antigenicity, and the preservation of histology from frozen specimens collected before and after the power outage caused by Hurricane Sandy. To analyze nucleic acid quality, we extracted both DNA and RNA and performed capillary electrophoresis to compare the quality and concentrations of the nucleic acids. To compare antigenicity, frozen sections were cut and immunostained for thyroid transcription factor 1 (TTF-1), a nuclear transcription protein commonly used as a diagnostic biomarker for multiple cancer types, including thyroid and lung cancers. Positive expression of TTF-1, as noted by homogenous nuclear staining, would demonstrate that the TTF-1 proteins could still bind antibodies and, therefore, that these proteins were not significantly degraded. Furthermore, representative frozen sections stained with hematoxylin and eosin were also assessed qualitatively by a trained pathologist to examine any possible histologic aberrations. Due to the similar quality of the tissue samples collected before and after the storm, Hurricane Sandy had no discernable effect on the quality of frozen specimens, and these specimens exposed to the natural disaster are still valuable research tools.
