Elimination of Hepatitis C Virus Among Users of Substances
- Conditions
- Hepatitis C in Substance Users
- Interventions
- Registration Number
- NCT05503979
- Lead Sponsor
- Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran
- Brief Summary
Substance users are a vulnerable group that should be prioritized in HCV (Hepatitis C Virus) elimination efforts in Mexico and in which it is feasible to carry out micro-elimination programs. It is an important group to treat both because of its high prevalence and because of the dynamic spread of infection among the general population. HCV seropositivity has not been documented in this group of people in Mexico City, the metropolitan area and the northern states of the country, nor has the sustained viral response been evaluated in this group of patients in the Mexican population.
- Detailed Description
The investigators would use a work team, the program and the value proposal would be presented to the local authorities, the coordinator of the national commission against dependencies and doctors. The investigators would use an algorithm designed for the first-step diagnosis of HCV in SUs (Substances Users) , and defined the key centers for screening and linking to care.
The project is planned as follows:
* Screening: SUs in centers of substance users in Mexico City, the metropolitan area and states in the North of the country will be evaluated with rapid tests. Those with a positive result will be selected.
* Diagnosis: Patients with a positive rapid test result will undergo a viral load test against HCV. Those with positive results will be selected.
* Link-up: Those who are confirmed positive will be profiled to receive treatment at INCMNSZ. they will receive damage reduction to prevent reinfection or primary infection in negatives (granted by the rehabilitation center).
* Treatment: The treatment will be received in a certified hospital (INCMNSZ) to treat patients with HCV infection, the treatment will be indicated by doctors who work in this hospital in the treatment consultations for hepatitis C or in centers with substance users with doctors trained to administer the treatment. This training will be received by telementoring. And also during the treatment, follow-up will be given with telementoring sessions if necessary. This group of people has personality characteristics that require a integral treatment, so it will be a integral and multidisciplinary treatment with psychological care and harm reduction (provided by the rehabilitation center)
* Confirm SVR: A viral load test will be performed 12 weeks after the end of treatment to corroborate SVR. They will be given after this a mentorship for harm reduction and advice against reinfections
The importance of this project is characterized by minimal monitoring, patients and doctors education by telementoring, multidisciplinary teams and integral treatment

Group Intervention Description Substances Users Sofosbuvir 400 MG / Velpatasvir 100 MG [Epclusa] Substances users confirmed with Viral Load for HCV. after that will be evaluated through laboratory studies (CBC and blood chemistry), HIV/HBV (Hepatitis B Virus) serology, fibrosis status will be evaluated through APRI (AST to Platelet Ratio Index) and FIB-4. The antiviral treatment (sofosbuvir/Velpatasvir) will be chosen according to the characteristics of each patient and follow-up will be maintained according to the national plan with a visit at the end of treatment and 12 weeks after its end to assess SVR. The importance of this project is characterized by minimal monitoring, patients and doctors education by telementoring, multidisciplinary teams and integral treatment.
- Primary Outcome Measures
Name Time Method Sustained viral response (SVR) in people who use substances in the Mexico City metropolitan area and the northern states of the country. through study completion, an average of 1 year Number por participants who achive SVR whit the treatment
- Secondary Outcome Measures
Name Time Method Seroprevalence and prevalence of HCV in people who use substances in the Mexico City metropolitan area and the northern states of the country. through study completion, an average of 1 year Number of participants with chronic HCV infection
No Sustained viral response (SVR) in people who use Substances in the Mexico City through study completion, an average of 1 year Number of participants who does not achive RVS
