Continuum of hepatitis C care cascade in prison and following release in the direct-acting antivirals era.

BACKGROUND: People with criminal justice involvement contribute remarkably to the rising hepatitis C virus (HCV) burden; however, the continuum of care is a major barrier to prison-based programs. We aimed to evaluate a comprehensive HCV care model in an Iranian provincial prison. METHODS: Between 2017-2018, in the Karaj Central Prison, newly admitted male inmates received HCV antibody testing and venipuncture for RNA testing (antibody-positive only). Participants with positive RNA underwent direct-acting antiviral (DAA) therapy (Sofosbuvir/Daclatasvir). Sustained virological response was evaluated at 12 weeks post-treatment (SVR12). RESULTS: Overall, from 3485 participants, 182 (5.2%) and 117 (3.4%) tested positive for HCV antibody and RNA, respectively. Among 116 patients who were eligible for treatment, 24% (n = 28) were released before treatment and 72% (n = 83) initiated DAA therapy, of whom 81% (n = 67/83) completed treatment in prison, and the rest were released. Of total released patients, 68% (n = 30/44) were linked to care in community, and 70% (n = 21/30) completed treatment, including 60% (n = 12/20) and 90% (n = 9/10) among those who were released before and during treatment, respectively. The overall HCV treatment uptake and completion were 89% (n = 103/116) and 85% (n = 88/103), respectively. From people who completed treatment, 43% (n = 38/88) attended for response assessment and all were cured (SVR12 = 100%). CONCLUSIONS: Integrated HCV care models are highly effective and can be significantly strengthened by post-release interventions. The close collaboration of community and prison healthcare systems is crucial to promote high levels of treatment adherence. Future studies should investigate the predictors of engagement with HCV care following release.

Incidence pattern and spatial analysis of breast cancer in Iranian women: Geographical Information System applications.

BACKGROUND: Breast cancer is the leading cancer in Iranian women, but no studies have yet been conducted on the distribution and pattern of its incidence. AIM: To perform a spatial analysis and determine the incidence pattern of breast cancer in the Islamic Republic of Iran. METHODS: This was a cross-sectional, pathology-based study of all new female patients with breast cancer registered in the Islamic Republic of Iran in 2011 (n=10 233). Initially, crude incidence rates were calculated for each province and the whole country per 100 000 person-years. Then, a direct standardization method and World Health Organization standard population were used to adjust for age effects on a geographical scale. Stata and Arc GIS software were used to calculate incidence rates and conduct spatial analysis. RESULTS: The mean (standard deviation) age of the patients was 50.9 (12.6) years. The national age-standardized incidence rate for breast cancer in women was 29.88 per 100 000 person-years, with a range of 5-72 in different provinces. The clustering incidence pattern was observed in Mazandaran, Tehran, Alborz, Isfahan and Markazi Provinces (P < 0.01). There was a significant cluster of high incidence of breast cancer in Iranian women. CONCLUSION: These findings may help to establish etiological hypotheses of cancer causation and identify spatial anomalies in cancer incidence or registration in the Islamic Republic of Iran. Our findings may also aid further research on the possible explanations for these clusters and associations.

Drug use and risk behaviour profile, and the prevalence of HIV, hepatitis C and hepatitis B among people with methamphetamine use in Iran.

BACKGROUND: Stimulants substances use, particularly methamphetamine use, is increasing globally, including in Iran. This study assessed the drug use and risk behaviour profile, and prevalence of HIV, hepatitis C virus (HCV), and hepatitis B virus (HBV) among a large population using methamphetamine as their primary drug in Iran. METHODS: This cross-sectional study was conducted in eight provinces of Iran. Individuals using methamphetamine for ≥3 months during the past three years, with no life-time history of injecting opioid drugs were enrolled. Drug use and risk behaviour data were collected through interviews. Blood samples were tested for HIV antibodies (HIV Ab), HCV antibodies (HCV Ab), and HBV surface antigen (HBs Ag). RESULT: Among 567 participated, 84% were men and mean age was 36 years. Smoking with pipe was the most common method of methamphetamine use (53%), while 13% had a history of injecting methamphetamine, among whom 30% shared needles or syringes. Among those having sex during intoxication phase (n = 270), 48% never used condom. The prevalence of HIV Ab, HCV Ab and HBs Ag was 6.7% (95%CI: 4.7-9.1), 19.4% (95%CI: 16.2-22.9) and 1.4% (95%CI: 0.6-2.7), respectively. Age ≥ 30 years (adjusted OR [aOR]: 2.10, 95%CI: 1.18-3.76), lower education (high school vs. tertiary education, aOR: 13.95, 95%CI: 1.90-102.60), and injecting methamphetamine (aOR: 1.92, 95%CI 1.10-3.35) were significantly associated with HCV exposure. No factor was found associated with HIV infection. Among those reporting no potential injecting or sexual risk factors, 19.8% and 6.8% have HCV Ab positive and HIV Ab positive, respectively. CONCLUSION: High prevalence of injecting and sexual risk behaviours, HIV infection and HCV exposure were found among individuals using methamphetamine as their primary drug, demonstrating them as an emerging population at risk of HIV and HCV in Iran. Targeted screening and harm reduction programs for this population are required.

Incidence of hepatocellular carcinoma in southeast iran.

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) is a well-known consequence of chronic liver disease (CLD). The aim of this study was to extract the HCC incidence rate in the province of Kerman, located in southern part of Iran, and compare the data with other parts of the country. MATERIALS AND METHODS: All medical records related to HCC were collected through hospitals or outpatient services in public or private centers. The records of all oncology, radiotherapy, and pathology centers in Kerman province were actively searched between 1999 and 2006. The annual incidence of HCC around the country was calculated, using the national cancer registry database provided by the Health Ministry of IR Iran from 2005 to 2006. Using Stata version 8, the crude and age-sex-standardized annual incidence rates were computed. RESULTS: The crude annual incidence rates of HCC per 100,000 persons in Kerman and Iran were 0.522 (95% CI = 0.238- 0.88) and 0.199 (95% CI = 0.167-0.234), respectively. When adjusting for age and sex, the annual incidence rates of HCC in Kerman and Iran were 0.7 (95% CI = 0.4-1.1) and 0.2 (95% CI = 0.2-0.3) per 100,000 persons, respectively (P<0.01).The mean age of patients in Kerman was around 5.5 years younger than other parts of Iran (56.17 ± 18.32 years versus 61.68 ± 14.62 years; P=0.004). CONCLUSIONS: In general, the incidence of HCC is not very high in Iran; however, the higher incidence of HCC in Kerman and also the lower age of onset mandates further research to detect HCC's risk factors in this part of country.
