Ordak M, Nasierowski T, Muszynska E, Bujalska-Zadrozny M. Psychoactive Substances Taken with Mephedrone and HCV Infection. J Clin Med 2021; 10:jcm10153218. [PMID: 34362002 PMCID: PMC8348849 DOI: 10.3390/jcm10153218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 07/16/2021] [Accepted: 07/21/2021] [Indexed: 11/24/2022] Open
Abstract
Background: In recent years, the observed frequency of hospitalization of patients taking mephedrone with other psychoactive substances has increased. There are no data in the literature on the effect of mephedrone use on liver function in patients, including the frequency of HCV infection. We have analysed the impact of taking mephedrone together with other psychoactive substances on the incidence of HCV infection. We have also analysed the effect of taking mephedrone with heroin, alcohol, and benzodiazepines on liver enzyme levels. Methods: The study included patients taking mephedrone with: alcohol (n = 115), heroin (n = 85) and benzodiazepines (n = 130) hospitalized in 2010–2018. The control group consisted of patients addicted to alcohol (n = 180), heroin (n = 221) and benzodiazepines (n = 152). Clinical data and laboratory findings were collected from medical records. Results: Taking mephedrone together with benzodiazepines is a statistically significant predictor of HCV infection in this group of patients, OR (8.44); 95% CI 5.63–12.64; p < 0.001). A statistically significant interaction of the group with HCV infection was observed, i.e., for the level of alanine transaminase (p < 0.001) and aspartate transaminase (p < 0.001). Increased levels of liver enzymes in each of the studied groups was characteristic in patients with HCV infection (p < 0.001). Taking additional mephedrone by this group of patients did not increase the level of liver enzymes. Conclusion: HCV infection is a statistically significant factor affecting the increase in liver enzymes levels in the group of patients taking mephedrone.

Phylogenetic and Phylodynamic Analyses of HCV Strains Circulating among Patients Using Injectable Drugs in Central Italy. Microorganisms 2021; 9:microorganisms9071432. [PMID: 34361868 PMCID: PMC8304011 DOI: 10.3390/microorganisms9071432] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 06/21/2021] [Accepted: 06/25/2021] [Indexed: 01/13/2023] Open
Abstract
Approximately 71 million people worldwide are infected with the hepatitis C virus (HCV). Injectable drug use represents the most common route of transmission in Europe and other developed countries. We studied the molecular characteristics of the HCV infection among mono-infected people who used drugs (PWUD) in Italy. Among 208 PWUD with anti-HCV antibodies, 101 (48.6%) were HCV RNA-positive, the majority (47%) were infected with the HCV genotype (Gt)1a, followed by Gt3a (34.9%), Gt4 (9.1%), Gt1b (4.5%), and Gt2 (4.5%). Bayesian phylogenetic analyses of clustered HCV NS5B sequences from 66 HCV-positive PWUDs with available plasma samples indicated age and neighborhood proximity as the most common characteristics between closely related HCV strains. Population dynamics, as measured by a coalescent Bayesian skyline analysis, revealed an increase in HCV Gt1a infections from the mid-1980s to mid-1990s. While HCV Gt3a infections were first detected in the 1980s, patient numbers with this genotype subtype remained relatively constant. For both Gt1a and Gt3a, Birth–Death Bayesian Skyline analyses produced higher reproduction numbers post 2014. For earlier time intervals, slow growths were observed for both Gt1a and Gt3a with reproduction numbers (Re) of approximately 1. The evolutionary rates for Gt1a and Gt3a were estimated as 2.23 × 10−4 and 3.85 × 10−4, respectively.

Hepatitis C virus infection status and associated factors among a multi-site sample of people who used illicit drugs in the Amazon region. BMC Infect Dis 2019; 19:634. [PMID: 31315569 PMCID: PMC6637600 DOI: 10.1186/s12879-019-4270-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Accepted: 07/10/2019] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Elevated rates of Hepatitis C Virus (HCV) infection have been reported in epidemiological studies with people who used illicit drugs (PWUIDs) in different Brazilian regions. In Brazil's Amazon region, studies have already identified the common use of illicit drugs among adolescents and the high prevalence of HCV infections among PWUIDs. However, all studies done with PWUIDs were conducted with small samples and within limited geographic coverage. This study determined the prevalence and risk factors for HCV infection in PWUIDs in the Amazon region, northern Brazil, as well as estimating the prevalence and factors associated with the HCV spontaneous clearance (HSC). METHODS This cross-sectional study accessed 1666 PWUIDs from multiple municipalities of the Amazon region. Socio-demographic, economic, drug use and health-related information were collected through interviews. Blood samples collected were tested for the presence of anti-HCV antibodies and RNA-HCV. HCV genotypes were identified by real-time polymerase chain reaction (PCR). Logistic regressions were run to identify factors independently associated with HCV infection status and HSC. RESULTS In total, 577 (34.6%) featured HCV antibodies, of which 384 (23.1%) had active HCV infection and 193 (11.6%) indicated HSC. Genotypes 1 (80.2%) and 3 (18.8%) were detected. HCV infection status was associated with the length of illicit drug use history, factors related to parenteral and sexual transmission, and factors of socio-economic marginalization leading to potential risk activities for HCV. HSC was associated with the ethnic (including indigenous) background of participants. CONCLUSIONS High levels of HCV infection were detected in PWUIDs. Genotype 1 was predominant. Intense use of illicit drugs, unprotected sexual intercourse, high number of sexual partners and social marginalization were associated with all HCV infection. HSC was associated with origin (Amazonian-born) and non-white (e.g., Black or Indigenous) of PWUIDs. These findings emphasize the need for improve HCV prevention and control services and care for PWUIDs in the Brazilian Amazon region.

Abstract
Introduction Drug abuse and co-occurring infections are associated with significant morbidity and mortality. In regions with high rates of drug usage, infections like hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) are highly prevalent. Epidemiological studies on HBV, HCV and HIV infections among users of illicit drugs are scarce in Turkey. The primary aim of this cross-sectional and retrospective study was to determine the hepatitis B surface antigen (HBsAg), anti-HCV antibody (anti-HCV) and anti-HIV antibody (anti-HIV) seroprevalences in drug users who applied to a psychiatric outpatient clinic of drug addiction of a university hospital. Secondarily, the assessment of HBsAg, anti-HCV and anti-HIV parameters among intravenous drug users was aimed. Methods Serum samples of all patients on probation who applied to a psychiatric outpatient clinic of drug addiction of a university hospital between 2013-2017 and sent to the department of medical microbiology for routine serologic testing were included in the study. The serologic results were obtained retrospectively from laboratory records. For the statistical analysis of the data IBM SPSS 20.0 program was used. Results Among the studied individuals, the ELISA results demonstrated the existence of HBsAg, anti-HCV and anti-HIV in 94 out of 4357 patients (2.2%), 27 out of 4451 patients (0.6%) and 10 (0.2%) out of 4464 patients, respectively. According to the records, 17 of the patients reported intravenous drug usage. Among this patient group, three patients were found to be anti-HCV positive and one patient was found to be anti-HIV positive. Conclusion In our study, the prevalence of HCV and HIV was increased in patients with intravenous drug usage, whereas in non-intravenous drug users the prevalence is similar to the normal population. In order to plan prevention and harm reduction services for this high-risk population, more national data is needed on HBV, HCV and HIV rates among this group.

Abstract
OBJECTIVE Cocaine/levamisole-associated autoimmunity syndrome (CLAAS) is a poorly understood form of drug-induced autoimmunity. Our goals were to better characterize the spectrum of clinical and immunologic features of CLAAS, to identify demographic risk factors, and to generate new hypotheses regarding pathogenesis. METHODS CLAAS subjects were identified between 2001 and 2015 at the University of Washington Medical Center, Harborview Medical Center, and affiliated clinics in Seattle, Washington, USA. Demographic, clinical, and immunologic variables were collected and correlated using contingency and logistic regression analyses. We used similar analyses to compare CLAAS subjects with all individuals exhibiting antineutrophil cytoplasmic antibodies (ANCA+) or cocaine use (Cocaine+) in an associated deidentified clinical data repository. RESULTS We identified 50 CLAAS subjects. Compared to all Cocaine+ individuals (n = 2740), CLAAS subjects were more likely to be female and less likely to self-identify as black/African American. CLAAS subjects showed several ANCA patterns, including anti-MPO (myeloperoxidase)/anti-PR3 (proteinase 3) dual reactivity, a finding that appears to be specific to CLAAS. Hematologic, renal, and skin abnormalities were most frequently reported, including neutropenia and skin purpura. Finally, we observed strong, independent associations between the cytoplasmic ANCA (C-ANCA) pattern and mortality. CONCLUSION We identify sex and race as important risk modifiers in the developing CLAAS among cocaine users. The development of C-ANCA was associated with increased mortality. Moreover, we confirm the enriched presence of anti-MPO/anti-PR3 dual reactivity in CLAAS, further supporting the diagnostic utility of this feature.

Abstract
Hepatitis C virus (HCV) infection causes acute and chronic liver disease and may lead to cirrhosis, liver failure or hepatocellular carcinoma. The behavior of illicit drug users (DUs) typically exposes them to risks of viral infection. In the Brazilian Amazon region, a number of studies have identified high rates of drug use among adolescents, and a high prevalence of HBV infection in DUs, disseminated by sexual and parenteral activities. However, the epidemiological scenario of HCV infection in the region is still poorly understood. This study determined the prevalence, genotypes, and risk factors for HCV infection among DUs of the Marajó Archipelago. This cross-sectional study collected samples and epidemiological information from DUs in 11 municipalities. The diagnosis was established by EIA and real-time PCR, and the samples were genotyped by multiplex real time PCR. The data were analyzed by simple and multiple logistical regression. In 466 DUs, 28.3% had anti-HCV antibodies, and 25.5% had HCV-RNA. In 92 injecting drug users, 88.0% had anti-HCV antibodies, and 80.4% had HCV-RNA. Genotypes 1 and 3 were detected, with three cases of mixed infections. The multivariate analysis indicated associations of HCV infection with age (≥ 35 years), tattoos, intravenous drug use, shared use of injection equipment, and the daily and long-term (> 3 years) use of illicit drugs. These findings will contribute to the development of effective measures for the prevention of HCV infection among Brazilian DUs, as well as its general population.

Abstract
Objectives Summarize hepatitis C virus (HCV) prevalence in injecting (IDU) and non-injecting drug users (NIDU), men who have sex with men (MSM), sex workers, and prison inmates in Latin America and the Caribbean (LAC). Methods Systematic review on HCV prevalence in sub-populations in LAC. Databases searched from 1-1-2000 to 10-30-2013. Inclusion criteria: prevalence studies in sub-populations in LAC. HCV-antibody was marker for prevalence of current/past HCV infection and HCV-RNA for prevalence of HCV current infection. Results IDU HCV current/past infection presented highest prevalence, from 1.7 % in Colombia to over 95 % in Ciudad Juarez and Tijuana, Mexico and pooled regional anti-HCV prevalence was 49 % (CI 95 % 22.6–76.3 %). NIDU, MSM and sex workers anti-HCV prevalence was below 10 %, and pooled regional prevalence of 4 % (CI 95 % 2.6–4.5 %), 3 % (CI 95 % 1.7–4.5 %) and 2 % (CI 95 % 1.0–3.4 %), respectively. Prison inmates presented higher values, but prevalence decreased over the 15-year time span (p < 0.001). Current HCV infection from three countries showed prevalence under 10 % in prison inmates and 1–46 % among drug users. Conclusions Disease burden is high and surveillance, prevention and treatment should target these groups in LAC.

Abstract
This study evaluated epidemiological factors for HCV infection
associated with sharing perforating and cutting instruments among candidates for
blood donation (CBD) in the city of Belém, Pará, Brazilian
Amazon. Two definitions of HCV infection cases were used: anti-HCV positivity
shown by EIA, and HCV-RNA detection by PCR. Infected and uninfected CBD
completed a questionnaire about possible risk factors associated with sharing
perforating and cutting instruments. The information was evaluated using simple
and multiple logistic regressions. Between May and November 2010, 146
(1.1%) persons with anti-HCV antibodies and 106
(0.8%) with HCV-RNA were detected among 13,772 CBD in Belém.
Risk factors associated with HCV infection based on the EIA (model 1)
and PCR (model 2) results were: use of needles and syringes sterilized
at home; shared use of razors at home, sharing of disposable razors in
barbershops, beauty salons etc.; and sharing manicure and pedicure material. The
models of HCV infection associated with sharing perforating and cutting
instruments should be taken into account by local and regional health
authorities and by those of other countries with similar cultural practices, in
order to provide useful information to guide political and public strategies to
control HCV transmission.

Abstract
BACKGROUND Currently, sharing of drug paraphernalia is the main form of HCV transmission worldwide. In South America, consistent findings indicate that shared sniffing equipment is an important factor in the spread of HCV among non-injecting drug users. Epidemiological data on the status of HCV infection in illicit drug users in the Amazon region are scarce, although reports of clinical cases of hepatitis or pathologies associated with HCV infection in other population groups are numerous. Thereby, this study investigated the prevalence, genotype frequency, and epidemiological factors associated with HCV infection in non-injecting drug users in the state of Pará, eastern Amazon. RESULTS During 2008-2011, 300 non-injecting drug users attending drug-treatment centers participated in this study. Most non-injecting drug users were male (63.7%). The mean age was 32.5 years. The non-injecting drugs most consumed were: cannabis (15.6%), cocaine paste (21.3%), and oxi cocaine (25.7%). Tobacco (60.9%) and alcohol (79.4%) were also commonly consumed. One hundred six (35.1%; CI 95%: 29.8 - 41.1) non-injecting drug users presented anti-HCV antibodies by EIA. The HCV-RNA prevalence was 28.0% (95% CI: 20.6 - 35.8). Genotypes 1 (76.9%) and 3 (23.1%) of HCV have been identified. A multivariate analysis demonstrated that HCV infection was independently associated with the following factors: "age (≥ 35 years)", "tattoos", "use of a needle or syringe sterilized at home", "shared use of drug paraphernalia", "uses drugs for more than 5 years", and "use of drugs everyday". CONCLUSIONS This study revealed a high prevalence of HCV infection in non-injecting drug users, and most infections are occasioned by genotype 1. Likely, HCV transmission is associated with the tattoos, the use of needle or syringe sterilized at home by people over the age of 35 years, and sharing, time and frequency of use of non-injecting drugs. These findings should serve as an incentive for the establishment of a program of Hepatitis C prevention and control by the local public-health authorities in order to develop effective policies and strategies for contain the spread of HCV infection.
