Projecting severe sequelae of injection-related hepatitis C virus epidemic in the UK. Part 1: Critical hepatitis C and injector data.

BACKGROUND: Hepatitis C is transmitted by transfusion of unscreened blood, through injecting drugs, from mother-to-child and, on occasion, sexually. Transmission generally requires that the infector is hepatitis C virus (HCV) RNA positive, a 'carrier'. About three-quarters of injectors who are hepatitis C antibody positive are HCV-RNA positive and so infectious to others. Incubation periods from HCV infection to cirrhosis and hepatocellular carcinoma are even longer than from HIV infection to AIDS, being counted in decades; they depend on age, gender, alcohol consumption and co-infection with other viruses. We identify 25 data sources that are available, or required, for projecting the severe sequelae of the injection-related hepatitis C epidemic. DATA SOURCES: Three data sources relate to hepatitis C diagnosis: register of confirmed HCV infections (with initial of first name + soundex of surname + date of birth + gender = master index, exposure category, year of starting to inject, and region); surveys of HCV test-uptake by injectors and others; documentation of pregnancy and its outcome in HCV-infected women (injectors and others). Four data sources relate to HCV prevalence and incidence among injectors and others: anonymous testing for HCV antibodies in blood or saliva (for sentinel groups ranging from new blood donors, pregnant women, patients awaiting kidney transplantation, non-injector prisoners, health-care workers, non-injector heterosexuals attending genitourinary medicine clinics; to injectors in the community, at drug treatment centres or in prison); historical data on HCV prevalence in injectors; HCV incidence studies in injectors; and uptake of harm reduction measures--frequency of sharing and methadone substitution--by injectors. Key reporting problems in HCV incidence studies, which inhibit checks on the convenient exponential assumption for time from start of injecting to hepatitis C infection, are discussed. Nine critical data sources are identified for monitoring the late sequelae of hepatitis C carriage, its investigation and treatment: linkage surveillance, for example by master index, to identify deaths, hospitalisations or cancer registrations among confirmed HCV infections; surveys of HCV status among patients who undergo liver biopsy, are newly diagnosed with cirrhosis or are newly diagnosed with liver cancer; surveys of liver-biopsy rate in HCV-infected injectors and others; uptake and outcome of interferon + ribavirin in the treatment of hepatitis C carriers; cohort studies of HCV progression; sample surveys of genotype in HCV-infected injectors, and others; acute hepatitis B infections and uptake of hepatitis B immunisation by injectors; liver transplantation in HCV-infected patients; and hepatitis C-status and other risk factors in deaths from cirrhosis or liver cancer, to determine whether they are HCV and injector-related. Finally, nine critical data sources are identified for quantitative understanding of the underlying injector epidemic: drug misuse databases plus capture-recapture methods to assess number of injectors, drug-related deaths by region to assess injector numbers; number of HIV-infected injectors; HIV progression in injectors; overdose and other causes of death in injectors; expert opinion on injector incidence historically, plus survey information on age-distribution at initiation and duration of injector careers; injector incidence historically inferred from hepatitis C infected blood donors; age-distribution of current injectors and at initiation, as a check on the assumptions made in stochastic simulation about injector incidence and 'outcidence' from injecting historically; mortality of former injectors; and general population or other survey ratios of surviving ever-injectors to injectors in the last 5 years, last year and currently, as a check on simulations. RECOMMENDATIONS: We recommend a common HCV diagnosis report form to improve ascertainment of risk-factor information, especially year of starting to inject--which is a key date epidemiologically. We also recommend updated surveys of current and former injectors' HCV-test uptake, or a denominator study that registers master index and risk factor information for all HCV testees. We recommend that injector surveys ask about typical frequency of needle sharing per 4 weeks in three distinct periods this year, last year and in the first year of injecting. We also recommend the location of stored historical samples from injectors to be tested retrospectively and anonymously for HCV antibodies. We recommend immediate attention to the uptake of, and response to, combination treatment by hepatitis C carriers who are former or recovering injectors. We rec

An outbreak of acute hepatitis B infection among injecting drug users in Inverclyde, Scotland.

This large outbreak of acute hepatitis B infection among injecting drug users (IDUs) was precipitated by an increase in injecting heroin use in Inverclyde in the West of Scotland, between 1997 and 1999. Ninety-two cases of hepatitis B infection in residents of Inverclyde were reported to Argyll and Clyde Health Board from January 1996 to December 1999. An investigation of risk factors found 87% (80/92) of the cases were IDUs, of whom four-fifths were men. Fifty six per cent of cases were aged 20-29 years old and 12% were aged 16-19 years old. Further investigations among this close community of young and relatively inexperienced IDUs revealed that many admitted to sharing injecting equipment particularly spoons, water and filters. Only a minority had been using local needle exchange facilities in the area. After public consultation a second needle exchange was opened in 1998 staffed by a dedicated needle exchange development worker who has continued to develop harm reduction services locally.

Hospital utilization and costs in a cohort of injection drug users.

BACKGROUND: Many injection drug users (IDUs) seek care at emergency departments and some require hospital admission because of late presentation in the course of their illness. We determined the predictors of frequent emergency department visits and hospital admissions among community-based IDUs and estimated the incremental hospital utilization costs incurred by IDUs with early HIV infection relative to costs incurred by HIV-negative IDUs. METHODS: The Vancouver Injection Drug User Study (VIDUS) is a prospective cohort study involving IDUs that began in 1996. Our analyses were restricted to the 598 participants who gave informed consent for our study. We used the participants' responses to the baseline VIDUS questionnaire and, from medical records at St. Paul's Hospital, Vancouver, we collected detailed information about the frequency of emergency department visits, hospital admissions and the primary diagnosis for all visits or hospital stays between May 1, 1996, and Aug. 31, 1999. The incremental difference in hospital utilization costs by HIV status was estimated, based on 105 admissions in a subgroup of 64 participants. RESULTS: A total of 440 (73.6%) of the 598 IDUs made 2763 visits to the emergency department at St. Paul's Hospital during the study period. Of these 440, 265 (160.2%) made frequent visits (3 or more). The following factors were associated with frequent use: HIV-positive status (seroprevalent: adjusted odds ratio [OR] 1.7, 95% confidence interval [CI] 1.2-2.6; seroconverted during study period: adjusted OR 3.0, 95% CI 1.6-5.7); more than 4 injections daily (adjusted OR 1.5, 95% CI 1.1-2.1); cocaine use more frequent than use of other drugs (adjusted OR 2.0, 95% CI 1.2-3.6); and unstable housing (adjusted OR 1.5, 95% CI 1.1-2.2). During the study period 210 of the participants were admitted to hospital 495 times; 118 (56.2%) of them were admitted frequently (2 or more admissions). The 2 most common reasons for admission were pneumonia (132 admissions among 79 patients) and soft-tissue infections (cellulitis and skin abscess) (90 admissions among 59 patients). The following factors were independently associated with frequent hospital admissions: HIV-positive status (seroprevalent: adjusted OR 5.4, 95% CI 3.4-8.6; seroconverted during study period: adjusted OR 2.9, 95% CI 1.4-6.0); and female sex (adjusted OR 1.8, 95% CI 1.1-3.1). The incremental hospital utilization costs incurred by HIV-positive IDUs relative to the costs incurred by HIV-negative IDUs were $1752 per year. INTERPRETATION: Hospital utilization was significantly higher among community-based IDUs with early HIV disease than among those who were HIV negative. Much of the hospital use was related to complications of injection drug use and may be reduced with the establishment of programs that integrate harm reduction strategies with primary care and addiction treatment.

Incidence of hepatitis C virus infection among injection drug users during an outbreak of HIV infection.

BACKGROUND: Beginning in 1994, Vancouver experienced an explosive outbreak of HIV infection among injection drug users (IDUs). The objectives of this study were to measure the prevalence and incidence of hepatitis C virus (HCV) infection in this context and to examine factors associated with HCV seroconversion among IDUs. METHODS: IDUs recruited through a study site and street outreach completed interviewer-administered questionnaires covering subjects' characteristics, behaviour, health status and service utilization and underwent serologic testing for HIV and HCV at baseline and semiannually thereafter. A Cox proportional hazards model was used to identify independent correlates of HCV seroconversion. RESULTS: As of Nov. 30, 1999, 1345 subjects had been recruited into the study cohort. The prevalence of anti-HCV antibodies was 81.6% (95% confidence interval [CI] 79.6% to 83.6%) at enrollment. Sixty-two HCV seroconversions occurred among 155 IDUs who were initially HCV negative and who returned for follow-up, for an overall incidence density rate of 29.1 per 100 person-years (95% CI 22.3 to 37.3). The HCV incidence remained above 16 per 100 person-years over 3 years of observation (December 1996 to November 1999), whereas HIV incidence declined from more than 19 to less than 5 per 100 person-years. Independent correlates of HCV seroconversion included female sex, cocaine use, injecting at least daily and frequent attendance at a needle exchange program. INTERPRETATION: Because of high transmissibility of HCV among those injecting frequently and using cocaine, the harm reduction initiatives deployed in Vancouver during the study period proved insufficient to eliminate hepatitis C transmission in this population.

Addiction medicine for the primary care physician.

Addiction and the consequences including medical, social, and legal are seen almost daily in a primary care office. To effectively deal with these problems it is imperative that the physician view addiction as a disease. This article explores the disease concept and the basis for the view as well as providing a guide to diagnosis and assessment. Useful screening tools are also provided as well as a discussion of biochemical markers currently available. A guideline for delivering the diagnosis is also discussed. An overview of the stages of treatment is provided as well, with particular emphasis on what the primary care physician needs to know. Outcome data regarding types of treatment looking at abstinence, harm reduction, and economic impacts are provided. Finally a look at parity for addiction treatment with a discussion of the cost and the benefits to society are also outlined.

The network of Centres for the Prevention and Treatment of Drug Addiction in the Republic of Slovenia.

The methadone maintenance program is one of the fundamental treatment and harm reduction programs in current drug policy that aims to protect the users of illegal drugs by increasing the number of users who make contact with the medical service and go on to join higher threshold therapy programs. National guidelines for management of drug addicts including methadone maintenance treatment were adopted by the Health Council at the Ministry of Health in 1994 and methadone maintenance program policies were confirmed. Fourteen regional Centers for the Prevention and Treatment of Drug Addictions have been established from 1995, and the professional staff working at the Centers have received additional training.

HIV/AIDS in prisons: more new developments.

Since our last review, there have been new developments in several jurisdictions in the area of HIV/AIDS and prisons. This column reviews some important developments in Canada and in the US: the results of the evaluation of HIV/AIDS harm-reduction measures in the Canadian federal prison system; another Canadian inmate's fight for methadone maintenance treatment in prison; an important article on health care in Canadian prisons which states that there is little evidence that the federal prison system "is making any serious effort to provide treatment to any drug users"; the US Supreme Court's refusal to review a lower court's ruling permitting Alabama prisons to segregate HIV-positive inmates; an important ruling stating that inmates are entitled to receive medications in jail without interruption; and research showing that women inmates in the US are 23 times more likely to have AIDS than women in the general population.

Social characteristics, HIV/AIDS knowledge, preventive practices and risk factors elicitation among prisoners in Lagos, Nigeria.

BACKGROUND: Although many behavioral research studies and public enlightenment campaigns have been undertaken by both government and non-governmental organizations in the general public, no such study has been documented on prison inmates in Nigeria. This study aimed at documenting the social characteristics, HIV/AIDS knowledge and preventive practices of selected prisoners in Nigeria. It also elicited risk factors HIV/AIDS transmission in Nigeria prisons. METHODS: A cross-sectional study of prison inmates using an anonymous risk-factors identification questionnaire was undertaken in January 1997. The Kiri-kiri (maximum, medium and female) prisons were selected by balloting. Thereafter, two hundred and fifty two inmates were selected by systematic random sampling method using the full listing of all inmates as at the time of the survey. The study comprised of an interview session using a well structured questionnaire to seek information about their social data, their knowledge about HIV/AIDS including its transmission and preventive social data, and their indulgence in HIV/AIDS risky behaviour. RESULTS: The majority (53.6%) of the respondents were in the age group 20-29 years, 18 (7.1%) were less than 20 years old one of whom was in the maximum-security prison and three were females (table 1). The majority (52%) had secondary education while 9.9% had tertiary education and 7.1% had no formal education. About 97.2% of the study population had heard about AIDS although only 20.6% had known or seen someone with AIDS before and about 34.1% knew the causative agent of AIDS. 60.3% knew the correct mode of transmission of AIDS. 15.5% claimed fidelity and 12.7 % claimed use of condom for casual sexual contact, were measures that could help prevent AIDS but 7.9% did not know any preventive measure. Since hearing about AIDS, 59.5% claimed to have taken steps to protect themselves. 42.7% of the 89 who had not taken any protective steps against AIDS had no knowledge of how to protect themselves. About 56.3% claimed to have used condom before although only 38.7% used it for their last sexual exposure while 28.2% claimed they used it for all casual sexual intercourse. Many (42.8%) said they knew that homosexuality was the most prevalent sexual practice in the prison while 28.6% claimed there was no sexual practice and 13.1% feigned ignorance of any sexual practices in the prisons. Many (53.2%) claimed to have multiple sexual partners although 94.8% denied any sexual practice whilst still in prison. CONCLUSION: This study demonstrated that (i) almost all THE prisoners studied had heard of AIDS although only a few had seen or known a case of AIDS; (ii) despite the fact that many of them knew the correct modes of transmission, many indulged in high risk behaviours for AIDS transmission; (iii) there is a considerable proportion of receptive naïve inmates who stand the risk of being infected due to their high level of ignorance about HIV/AIDS. Well designed information, education and communication (IEC) programmes on AIDS with such formidable support structures as the provision of harm-reduction devices and risk-reduction counselling are urgently recommended for the Nigerian prisoners to effectively combat the imminent HIV/AIDS epidemic among the prison inmates.

Microbicides to prevent heterosexual transmission of HIV: ten years down the road.

The development of topical microbicides for HIV prevention originated in response to the unabated spread of HIV despite the availability of an effective HIV prevention tool (condoms), as well as the lack of an effective HIV vaccine. Initially, hopes were pinned on existing over-the-counter spermicides containing nonoxynol-9. Concern about the toxicity of nonoxynol-9 with frequent use, and its small or nonexistent protective effect against HIV and other sexually transmitted infections (STIs), has spurred the development of new microbicides with a number of novel mechanisms of action. Significant progress has been made in the last decade. The microbicides pipeline currently contains approximately 34 products in preclinical development, 15 in Phase I safety trials, four in Phase II expanded safety and preliminary effectiveness trials, and three in Phase II/III or Phase III effectiveness trials. Laboratory and clinical research has been complemented by a growing body of research and literature on microbicide acceptability, harm reduction and dual protection strategies, and potential markets. However, many challenges remain, including the need for a significant increase in investment to accelerate product development and complementary research, and to plan for availability and access once effective microbicides are available.

Drug use among the urban poor in Kolkata: behaviour and environment correlates of low HIV infection.

BACKGROUND: HIV infection in injecting drug users (IDUs) has worked as a driving force for further spread of the virus in other population groups. Major metropolitan cities such as Mumbai, Kolkota, Chennai and Delhi have seen a diffusion of injecting drug use within the last decade. The prevalence of HIV infection among injectors ranges from 2% to 30%. Identifying effective interventional elements that have kept the prevalence of HIV low for the past 7 years among IDUs of Kolkata is thus of public health importance. METHODS: A purposive sample of opioid/opiate users was studied. Primary and secondary data on drug users, law-enforcement environment, records at drug treatment centres, jail admission data related to the 'Narcotic Drug and Psychotropic Substance Act' and interventions in other risk groups were collected. Laboratory tests for HIV, hepatitis B surface antigen and syphilis were done on consenting IDUs (n=129) and non-IDUs (n=120). For univariate and multivariate analysis, IDUs were taken as cases and non-IDUs as controls. RESULT: Of the IDUs, 2% were positive for HIV. No non-IDU was HIV-positive. Significantly more non-IDUs (10% v. 4%, p=0.05) were positive for syphilis. Sharing injection equipment within the past 6 months was reported by 71% of IDUs; sharing partners were stable and ranged from 1 to 3. More IDUs compared to non-IDUs reported being in touch with intervention programmes. The police has been tolerant to needle-syringe exchange and oral sublingual buprenorphine substitution conducted in Kolkata. Unlike in the early 1990s, non-IDUs did not switch to injecting during non-availability of brown sugar in the latter half of the 1990s and instead sought tratment. The availability of high quality heroin (>20%-50%) was low and the proportion of moderate quality heroin (>10%-20%) went up during these times due to increased police seizures. No intervention exists in jails despite the fact that a large number of drug users spend time in jail. CONCLUSION: Stable and few injection equipment-sharing partners of IDUs, launching of early targeted interventions among IDUs and sex workers in the city, police tolerance to harm reduction activities and preference of non-IDUs for detoxification during heroin draught periods have kept HIV prevalence at a low level among drug users of Kolkata for the past 7 years. immediate launching of interventions for drug users in jails seems necessary. Similar multi-pronged strategies with targeted and environmental intervention could work in other settings as well.

Methadone treatment in Ontario after the 1996 regulation reforms. Results of a physician survey.

Over two decades of rather restrictive regulations have kept the availability of methadone treatment (MT) at low levels in the province of Ontario, Canada. Regulatory changes in the Province of Ontario in the mid-1990s relaxed relevant authorization and treatment practice guidelines. Subsequently, the number of physicians authorized for methadone treatment and treatment spots increased substantially. A large number of the newly authorized physicians are general/local medical practitioners. This study reports on the results of a survey conducted with the majority of MT prescribing physicians in Ontario authorized at the time of study. Physicians were surveyed on their attitudes and practices with regards to the MT authorization system, treatment approaches, requirements and workload, patient 'stability', additional opiate substitution treatment needs, and with regards to general issues and concerns about the new MT governance system. The article also discusses patterns and differences that were found between physicians when comparing their geographic location, whether they see themselves practicing under a 'harm reduction' or an 'abstinence' approach, and whether they received MT authorization under the old or the new guidelines. It is concluded that the liberalized regulations and the increased incorporation of local physicians seems to provide for an overall more desirable system of governance of MT. However, some relevant concerns about the current system exist and are discussed.

Illicit drug use related attendances at accident and emergency services in Aberdeen: a prospective six month survey.

OBJECTIVE: To quantify and examine the nature of known illicit drug related attendances at the Accident and Emergency Department of Aberdeen Royal Hospital over a six month period. DESIGN: A structured questionnaire was completed by Accident and Emergency staff. SETTING: The Accident and Emergency Department of Aberdeen Royal Hospital. SUBJECTS: All patients presenting at the Accident and Emergency Department as a result of known illicit drug use between November 1996 to April 1997 inclusive. RESULTS: One hundred and fifty seven subjects presented at Accident and Emergency during the six month period. Peak attendance was between 18.00 and 21.00 hours. Twenty seven percent of patients chose to visit Accident and Emergency rather than their own general practitioner. Thirty seven percent had no involvement with any health care professional regarding their drug use. Heroin was used by 62% of cases of which the majority (94.9%) had injected and stimulants such as amphetamine and ecstasy were used by a large proportion of cases. Only 4.5% of subjects admitted to not using clean equipment yet 15% admitted to have loaned equipment (to someone else) and 22% of subjects had injecting related problems. Thirteen percent of subjects were considered unco-operative by staff. Fifty four percent of subjects required admission to a ward and ten patients (6%) died. CONCLUSION: Heroin continues to be the main drug causing major health problems. Harm reduction messages are not adequately reaching/or being taken up by drug users given the high proportion with injecting related problems and those being prepared to lend needles. The receptive attitude amongst subjects highlighted the opportunity for patient education as well as giving contact addresses of relevant organisations.

['Treatment of drug-addicted detainees': and advisory report by the Health Council of the Netherlands].

The Minister of Health, Welfare and Sport and the Minister of Justice requested advice from the Health Council of the Netherlands, on options for the treatment of detainees addicted to drugs. It is estimated that 15,000 to 23,000 people per year with addiction problems are detained. On the basis of the Custodial Institutions Act detainees have the right to adequate medical, psychological and psychiatric care, including treatment for drug addiction. The legal possibilities for using compulsion in the treatment of addicted persons in detention are very limited. A consensus needs to be reached on methadone medication; professional groups must reach this consensus. As well as abstinence, Addiction Support Sections should aim to achieve harm reduction, for example, by means of stabilisation with a maintenance dose of methadone. The success of interventions among addicted detainees is largely dependent on both the introduction of pressure in the area of follow-up care and the continuity of care. Bearing in mind the frequent psychiatric comorbidity, more psychiatric care should be available within the penitentiary setting. The Penal Care Facility for Addicts [Dutch acronym: SOV] is a new sanction option in the Penal Code with which drug-addicted repeat offenders can be involuntarily admitted to a drug addiction treatment centre for a maximum of 2 years. There is not enough scientific evidence to support the effectiveness of the SOV approach. The compulsory placement of an addict in the SOV could reduce the addict's motivation to do something about his addiction problem. SOV is a harsh sanction that should only be used once lighter sanctions (based on pressure by means of special conditions) have been shown to be ineffective for the persons concerned.

Temporal correlation between opiate seizures in East/Southeast Asia and B.C. heroin deaths: a transoceanic model of heroin death risk.

BACKGROUND: Because heroin supply changes cannot be measured directly, their impact on populations is poorly understood. British Columbia has experienced an injection drug use epidemic since the 1980s that resulted in 2,590 illicit drug deaths from 1990-1999. Since previous work indicates heroin seizures can correlate with supply and B.C. receives heroin only from Southeast Asia, this study examined B.C. heroin deaths against opiate seizures in East/Southeast Asia. METHODS: Opiate seizures in East/Southeast Asia and data from two B.C. mortality datasets containing heroin deaths were examined. The Pearson correlation coefficient for seizures against each mortality dataset was determined. RESULTS: Opiate seizures, all illicit drug deaths and all opiate deaths concurrently increased twice and decreased twice from 1989-1999, and all reached new peak values in 1993. Three B.C. sub-regions exhibited illicit drug deaths rate trends concurrent with the three principal datasets studied. The Pearson correlation coefficient for opiate-induced deaths against opiate seizures from 1980-1999 was R=0.915 (p<0.0001), and for illicit drug deaths against opiate seizures from 1987-1999 was R=0.896 (p<0.0001). CONCLUSIONS: From 1980-1999, opiate seizures in East/Southeast Asia were very strongly correlated with B.C. opiate and illicit drug deaths. The number of B.C. heroin-related deaths may be strongly linked to heroin supply. Enforcement services are not effective in preventing harm caused by heroin in B.C.; therefore, Canada should examine other methods to prevent harm. The case for harm reduction is strengthened by the ineffectiveness of enforcement and the unlikelihood of imminent eradication of heroin production in Southeast Asia.

Reconsideration of contemporary U.S. drug policy.

In their recent book Drug War Heresies: Learning From Other Vices, Times, and Places (Cambridge: Cambridge University Press, 2001), MacCoun and Reuter challenge the continuation of contemporary U.S. drug policy. Depenalization and legalization of illicit drugs are evaluated as alternatives to U.S. prohibition policy, with harm reduction (mitigation of social damages) as the criterion for guiding drug regime change. The appraisal encompasses an analysis of underlying philosophical and social mechanisms of current U.S. policy as well as drawing analogies from a comprehensive review of American vices and also Western European governmental interventions into illicit drug activities. What is apparent is that the evaluation and the available evidence entail substantial complexity and do not readily present unequivocal positions. The evaluation also strongly indicates that considerable difficulty would be encountered not only for the implementation of alternative regimes but also for the engagement in open political discussion of prohibition alternatives.
