Association of genetic variants in RAB23 and ANXA11 with uveitis in sarcoidosis.

Purpose: Uveitis occurs in a subset of patients with sarcoidosis. The purpose of this study was to determine whether genetic variants that have been associated previously with overall sarcoidosis are associated with increased risk of developing uveitis. Methods: Seventy-seven subjects were enrolled, including 45 patients diagnosed with sarcoidosis-related uveitis as cases and 32 patients with systemic sarcoidosis without ocular involvement as controls. Thirty-eight single nucleotide polymorphisms (SNPs) previously associated with sarcoidosis, sarcoidosis severity, or other organ-specific sarcoidosis involvement were identified. Allele frequencies in ocular sarcoidosis cases versus controls were compared using the chi-square test, and p values were corrected for multiple hypotheses testing using permutation. All analyses were conducted with PLINK. Results: SNPs rs1040461 and rs61860052, in ras-related protein RAS23 (RAB23) and annexin A11 (ANXA11) genes, respectively, were associated with sarcoidosis-associated uveitis. The T allele of rs1040461 and the A allele of rs61860052 were found to be more prevalent in ocular sarcoidosis cases. These associations remained after correction for the multiple hypotheses tested (p=0.01 and p=0.02). In a subanalysis of Caucasian Americans only, two additional variants within the major histocompatibility complex (MHC) genes on chromosome 6, in HLA-DRB5 and HLA-DRB1, were associated with uveitis as well (p=0.009 and p=0.04). Conclusions: Genetic variants in RAB23 and ANXA11 genes were associated with an increased risk of sarcoidosis-associated uveitis. These loci have previously been associated with overall sarcoidosis risk.

Factors affecting clinician educator encouragement of routine HIV testing among trainees.

BACKGROUND: Adoption of CDC recommendations for routine, voluntary HIV screening of all Americans age 13­64 years has been slow. One method to increase adherence to clinical practice guidelines is through medical school and residency training. OBJECTIVE: To explore the attitudes, barriers, and behaviors of clinician educators (CEs) regarding advocating routine HIV testing to their trainees. DESIGN/PARTICIPANTS: We analyzed CE responses to a 2009 survey of Society of General Internal Medicine members from community, VA, and university-affiliated clinics regarding HIV testing practices. MAIN MEASURES: Clinician educators were asked about their outpatient practices, knowledge and attitudes regarding the revised CDC recommendations and whether they encouraged trainees to perform routine HIV testing. Associations between HIV testing knowledge and attitudes and encouraging trainees to perform routine HIV testing were estimated using bivariate and multivariable logistic regression. RESULTS: Of 515 respondents, 367 (71.3%) indicated they supervised trainees in an outpatient general internal medicine clinic. These CEs demonstrated suboptimal knowledge of CDC guidelines and over a third reported continued risk-based testing. Among CEs, 196 (53.4%) reported that they encourage trainees to perform routine HIV testing. Higher knowledge scores (aOR 5.10 (2.16, 12.0)) and more positive attitudes toward testing (aOR 8.83 (4.21, 18.5)) were independently associated with encouraging trainees to screen for HIV. Reasons for not encouraging trainees to screen included perceived low local prevalence (37.2%), competing teaching priorities (34.6%), and a busy clinic environment (34.0%). CONCLUSIONS: Clinician educators have a special role in the dissemination of the CDC recommendations as they impact the knowledge and attitudes of newly practicing physicians. Despite awareness of CDC recommendations, many CEs do not recommend universal HIV testing to trainees. Interventions that improve faculty knowledge of HIV testing recommendations and address barriers in resident clinics may enhance adoption of routine HIV testing.

Hepatic safety and antiretroviral effectiveness in HIV-infected patients receiving naltrexone.

BACKGROUND: We sought to determine the impact of naltrexone on hepatic enzymes and HIV biomarkers in HIV-infected patients. METHODS: We used data from the Veterans Aging Cohort Study-Virtual Cohort, an electronic database of administrative, pharmacy, and laboratory data. We restricted our sample to HIV-infected patients who received an initial oral naltrexone prescription of at least 7 days duration. We examined aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and HIV biomarker (CD4 and HIV RNA) values for the 365 days prior to, during, and for the 365 days post-naltrexone prescription. We also examined cases of liver enzyme elevation (LEE; defined as >5 times baseline ALT or AST or >3.5 times baseline if baseline ALT or AST was >40 IU/l). RESULTS: Of 114 HIV-infected individuals, 97% were men, 45% white, 57% Hepatitis C co-infected; median age was 49 years; 89% of the sample had a history of alcohol dependence and 32% had opioid dependence. Median duration of naltrexone prescription was 49 (interquartile range 30 to 83) days, representing 9,525 person-days of naltrexone use. Mean ALT and AST levels remained below the upper limit of normal. Two cases of LEE occurred. Mean CD4 count remained stable and mean HIV RNA decreased after naltrexone prescription. CONCLUSIONS: In HIV-infected patients, oral naltrexone is rarely associated with clinically significant ALT or AST changes and does not have a negative impact on biologic parameters. Therefore, HIV-infected patients with alcohol or opioid dependence can be treated with naltrexone.

Provider and practice characteristics associated with use of rapid HIV Testing by general internists.

BACKGROUND: Rapid HIV testing could increase routine HIV testing. Most previous studies of rapid testing were conducted in acute care settings, and few described the primary care providers' perspective. OBJECTIVE: To identify characteristics of general internal medicine physicians with access to rapid HIV testing, and to determine whether such access is associated with differences in HIV-testing practices or perceived HIV-testing barriers. DESIGN: Web-based cross-sectional survey conducted in 2009. PARTICIPANTS: A total of 406 physician members of the Society of General Internal Medicine who supervise residents or provide care in outpatient settings. MAIN MEASURES: Surveys assessed provider and practice characteristics, HIV-testing types, HIV-testing behavior, and potential barriers to HIV testing. RESULTS: Among respondents, 15% had access to rapid HIV testing. In multivariable analysis, physicians were more likely to report access to rapid testing if they were non-white (OR 0.45, 95% CI 0.22, 0.91), had more years since completing training (OR 1.06, 95% CI 1.02, 1.10), practiced in the northeastern US (OR 2.35; 95% CI 1.28, 4.32), or their practice included a higher percentage of uninsured patients (OR 1.03; 95% CI 1.01, 1.04). Internists with access to rapid testing reported fewer barriers to HIV testing. More respondents with rapid than standard testing reported at least 25% of their patients received HIV testing (51% versus 35%, p = 0.02). However, access to rapid HIV testing was not significantly associated with the estimated proportion of patients receiving HIV testing within the previous 30 days (7.24% vs. 4.58%, p = 0.06). CONCLUSION: Relatively few internists have access to rapid HIV testing in outpatient settings, with greater availability of rapid testing in community-based clinics and in the northeastern US. Future research may determine whether access to rapid testing in primary care settings will impact routinizing HIV testing.

Food insecurity is associated with poor virologic response among HIV-infected patients receiving antiretroviral medications.

BACKGROUND AND OBJECTIVE: Food insecurity negatively impacts HIV disease outcomes in international settings. No large scale U.S. studies have investigated the association between food insecurity and severity of HIV disease or the mechanism of this possible association. The objective of this study was to examine the impact of food insecurity on HIV disease outcomes in a large cohort of HIV-infected patients receiving antiretroviral medications. DESIGN: This is a cross-sectional study. PARTICIPANTS AND SETTING: Participants were HIV-infected patients enrolled in the Veterans Aging Cohort Study between 2002-2008 who were receiving antiretroviral medications. MAIN MEASUREMENTS: Participants reporting "concern about having enough food for you or your family in the past 30 days" were defined as food insecure. Using multivariable logistic regression, we explored the association between food insecurity and both low CD4 counts (<200 cells/µL) and unsuppressed HIV-1 RNA (>500 copies/mL). We then performed mediation analysis to examine whether antiretroviral adherence or body mass index mediates the observed associations. KEY RESULTS: Among 2353 HIV-infected participants receiving antiretroviral medications, 24% reported food insecurity. In adjusted analyses, food insecure participants were more likely to have an unsuppressed HIV-1 RNA (AOR 1.37, 95% CI 1.09, 1.73) compared to food secure participants. Mediation analysis revealed that neither antiretroviral medication adherence nor body mass index contributes to the association between food insecurity and unsuppressed HIV-1 RNA. Food insecurity was not independently associated with low CD4 counts. CONCLUSIONS: Among HIV-infected participants receiving antiretroviral medications, food insecurity is associated with unsuppressed viral load and may render treatment less effective. Longitudinal studies are needed to test the potential causal association between food insecurity, lack of virologic suppression, and additional HIV outcomes.

Oral substitution treatment of injecting opioid users for prevention of HIV infection.

BACKGROUND: Injecting drug users are vulnerable to infection with Human Immunodeficiency Virus (HIV) and other blood borne viruses as a result of collective use of injecting equipment as well as sexual behaviour OBJECTIVES: To assess the effect of oral substitution treatment for opioid dependent injecting drug users on risk behaviours and rates of HIV infections SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and PsycINFO to May 2011. We also searched reference lists of articles, reviews and conference abstracts SELECTION CRITERIA: Studies were required to consider the incidence of risk behaviours, or the incidence of HIV infection related to substitution treatment of opioid dependence. All types of original studies were considered. Two authors independently assessed each study for inclusion DATA COLLECTION AND ANALYSIS: Two authors independently extracted key information from each of the included studies. Any differences were resolved by discussion or by referral to a third author. MAIN RESULTS: Thirty-eight studies, involving some 12,400 participants, were included. The majority were descriptive studies, or randomisation processes did not relate to the data extracted, and most studies were judged to be at high risk of bias. Studies consistently show that oral substitution treatment for opioid-dependent injecting drug users with methadone or buprenorphine is associated with statistically significant reductions in illicit opioid use, injecting use and sharing of injecting equipment. It is also associated with reductions in the proportion of injecting drug users reporting multiple sex partners or exchanges of sex for drugs or money, but has little effect on condom use. It appears that the reductions in risk behaviours related to drug use do translate into reductions in cases of HIV infection. However, because of the high risk of bias and variability in several aspects of the studies, combined totals were not calculated. AUTHORS' CONCLUSIONS: Oral substitution treatment for injecting opioid users reduces drug-related behaviours with a high risk of HIV transmission, but has less effect on sex-related risk behaviours. The lack of data from randomised controlled studies limits the strength of the evidence presented in this review.

A meta-analysis of the efficacy of nonphysician brief interventions for unhealthy alcohol use: implications for the patient-centered medical home.

Brief physician interventions can reduce alcohol consumption. Physicians may not have the time to provide brief interventions, and it is unclear whether nonphysicians can do so effectively. We conducted a systematic review and meta-analysis to examine the efficacy of brief interventions by nonphysician clinicians for unhealthy alcohol use. We searched the English-language literature in MEDLINE and other databases covering the domains of alcohol problems, primary care, nonphysician, and brief interventions. Studies of brief interventions delivered at least in part by nonphysicians in primary care and examining drinking outcomes were included. Sensitivity analyses examined the effect of excluding studies that contributed disproportionately to the heterogeneity of results. Thirteen studies, conducted 1996-2008, met our criteria. Seven studies with a total of 2,633 patients were included in the meta-analysis. Nonphysician interventions were associated with 1.7 (95% confidence interval [CI]=-.03 to -3.5) fewer standard drinks per week than control conditions (p = .054). Excluding the one study that increased heterogeneity, the effect was smaller but reached statistical significance; nonphysician counseling was associated with 1.4 (95% CI = .3- 2.4) fewer standard drinks per week compared to control (p = .012). Nonphysician brief interventions are modestly effective at reducing drinking in primary care patients with unhealthy alcohol use.

Effect of incarceration history on outcomes of primary care office-based buprenorphine/naloxone.

BACKGROUND: Behaviors associated with opioid dependence often involve criminal activity, which can lead to incarceration. The impact of a history of incarceration on outcomes in primary care office-based buprenorphine/naloxone is not known. OBJECTIVE: The purpose of this study is to determine whether having a history of incarceration affects response to primary care office-based buprenorphine/naloxone treatment. DESIGN: In this post hoc secondary analysis of a randomized clinical trial, we compared demographic, clinical characteristics, and treatment outcomes among 166 participants receiving primary care office-based buprenorphine/naloxone treatment stratifying on history of incarceration. MAIN RESULTS: Participants with a history of incarceration have similar treatment outcomes with primary care office-based buprenorphine/naloxone than those without a history of incarceration (consecutive weeks of opioid-negative urine samples, 6.2 vs. 5.9, p = 0.43; treatment retention, 38% vs. 46%, p = 0.28). CONCLUSIONS: Prior history of incarceration does not appear to impact primary care office-based treatment of opioid dependence with buprenorphine/naloxone. Community health care providers can be reassured that initiating buprenorphine/naloxone in opioid dependent individuals with a history of incarceration will have similar outcomes as those without this history.

Drug interactions of clinical importance among the opioids, methadone and buprenorphine, and other frequently prescribed medications: a review.

Drug interactions are a leading cause of morbidity and mortality. Methadone and buprenorphine are frequently prescribed for the treatment of opioid addiction. Patients needing treatment with these medications often have co-occurring medical and mental illnesses that require medication treatment. The abuse of illicit substances is also common in opioid-addicted individuals. These clinical realities place patients being treated with methadone and buprenorphine at risk for potentially toxic drug interactions. A substantial literature has accumulated on drug interactions between either methadone or buprenorphine with other medications when ingested concomitantly by humans. This review summarizes current literature in this area.

Substance use in patients with sexually transmitted infections: results from a national U.S. survey.

Little is known about the prevalence and correlates of substance use in patients diagnosed with sexually transmitted infections (STIs) in the general population. We examined the relationship between STIs and substance use. Of the 54,623 respondents, 1% reported a past-year STI. STI was associated with alcohol abuse/dependence (AOR 1.8, 95% CI 1.1-3.3), and marijuana use (AOR 2.0, 95% CI 1.4-3.0); but not with past-year alcohol use, cocaine use, nonmedical use of prescription opioids, or past-month binge or heavy drinking. A diagnosis of an STI should prompt clinicians to screen for substance use, in particular, alcohol abuse/dependence and marijuana use.

The association between cocaine use and treatment outcomes in patients receiving office-based buprenorphine/naloxone for the treatment of opioid dependence.

Cocaine use in patients receiving methadone is associated with worse treatment outcomes. The association between cocaine use and office-based buprenorphine/naloxone treatment outcomes is not known. We evaluated the association between baseline and in-treatment cocaine use, treatment retention, and urine toxicology results in 162 patients enrolled in a 24-week trial of primary care office-based buprenorphine/naloxone maintenance. Patients with baseline cocaine metabolite-negative urine toxicology tests compared with those with cocaine metabolite-positive tests had more mean weeks of treatment retention (18.3 vs. 15.8, p = .04), a greater percentage completed 24 weeks of treatment (50% vs. 33%, p = .04) and had a greater percentage of opioid-negative urines (47% vs. 34%, p = .02). Patients with in-treatment cocaine metabolite-negative urine toxicology tests compared with cocaine metabolite-positive patients had more mean weeks of treatment retention (19.0 vs. 16.5, p = .003), a greater percentage completed 24 weeks of treatment (60% vs. 30%, p < .001), and had a greater percentage of opioid-negative urines (51% vs. 35%, p = .001). We conclude that both baseline and in-treatment cocaine use is associated with worse treatment outcomes in patients receiving office-based buprenorphine/naloxone and may benefit from targeted interventions.

Counseling plus buprenorphine-naloxone maintenance therapy for opioid dependence.

BACKGROUND: The optimal level of counseling and frequency of attendance for medication distribution has not been established for the primary care, office-based buprenorphine-naloxone treatment of opioid dependence. METHODS: We conducted a 24-week randomized, controlled clinical trial with 166 patients assigned to one of three treatments: standard medical management and either once-weekly or thrice-weekly medication dispensing or enhanced medical management and thrice-weekly medication dispensing. Standard medical management was brief, manual-guided, medically focused counseling; enhanced management was similar, but each session was extended. The primary outcomes were the self-reported frequency of illicit opioid use, the percentage of opioid-negative urine specimens, and the maximum number of consecutive weeks of abstinence from illicit opioids. RESULTS: The three treatments had similar efficacies with respect to the mean percentage of opioid-negative urine specimens (standard medical management and once-weekly medication dispensing, 44 percent; standard medical management and thrice-weekly medication dispensing, 40 percent; and enhanced medical management and thrice-weekly medication dispensing, 40 percent; P=0.82) and the maximum number of consecutive weeks during which patients were abstinent from illicit opioids. All three treatments were associated with significant reductions from baseline in the frequency of illicit opioid use, but there were no significant differences among the treatments. The proportion of patients remaining in the study at 24 weeks did not differ significantly among the patients receiving standard medical management and once-weekly medication dispensing (48 percent) or thrice-weekly medication dispensing (43 percent) or enhanced medical management and thrice-weekly medication dispensing (39 percent) (P=0.64). Adherence to buprenorphine-naloxone treatment varied; increased adherence was associated with improved treatment outcomes. CONCLUSIONS: Among patients receiving buprenorphine-naloxone in primary care for opioid dependence, the efficacy of brief weekly counseling and once-weekly medication dispensing did not differ significantly from that of extended weekly counseling and thrice-weekly dispensing. Strategies to improve buprenorphine-naloxone adherence are needed. (ClinicalTrials.gov number, NCT00023283 [ClinicalTrials.gov].).

Integrating buprenorphine treatment into office-based practice: a qualitative study.

BACKGROUND: Despite the availability and demonstrated effectiveness of office-based buprenorphine maintenance treatment (BMT), the systematic examination of physicians' attitudes towards this new medical practice has been largely neglected. OBJECTIVE: To identify facilitators and barriers to the potential or actual implementation of BMT by office-based medical providers. DESIGN: Qualitative study using individual and group semi-structured interviews. PARTICIPANTS: Twenty-three practicing office-based physicians in New England. APPROACH: Interviews were audiotaped, transcribed, and entered into a qualitative software program. The transcripts were thematically coded using the constant comparative method by a multidisciplinary team. RESULTS: Eighty percent of the physicians were white; 55% were women. The mean number of years since graduating medical school was 14 (SD = 10). The primary areas of clinical specialization were internal medicine (50%), infectious disease (20%), and addiction medicine (15%). Physicians identified physician, patient, and logistical factors that would either facilitate or serve as a barrier to their integration of BMT into clinical practice. Physician facilitators included promoting continuity of patient care, positive perceptions of BMT, and viewing BMT as a positive alternative to methadone maintenance. Physician barriers included competing activities, lack of interest, and lack of expertise in addiction treatment. Physicians' perceptions of patient-related barriers included concerns about confidentiality and cost, and low motivation for treatment. Perceived logistical barriers included lack of remuneration for BMT, limited ancillary support for physicians, not enough time, and a perceived low prevalence of opioid dependence in physicians' practices. CONCLUSIONS: Addressing physicians' perceptions of facilitators and barriers to BMT is crucial to supporting the further expansion of BMT into primary care and office-based practices.

Narrative review: buprenorphine for opioid-dependent patients in office practice.

The profile of opioid dependence in the United States is changing. Abuse of prescription opioids is more common than that of illicit opioids: Recent data indicate that approximately 1.6 million persons abuse or are dependent on prescription opioids, whereas 323,000 abuse or are dependent on heroin. Despite this prevalence, nearly 80% of opioid-dependent persons remain untreated. One option for expanding treatment is the use of buprenorphine and the buprenorphine-naloxone combination. Buprenorphine is a partial opioid agonist that can be prescribed by trained physicians and dispensed at pharmacies. This article addresses the clinical presentation of a patient with opioid dependence and describes the relatively new practice of office-based treatment with buprenorphine-naloxone. The different components of treatment; the role of the physician who provides this treatment; and the logistics of treating this growing, multifaceted patient population are also examined.

The impact of alcohol use on depressive symptoms in human immunodeficiency virus-infected patients.

AIMS: To examine the impact of alcohol use on depressive symptoms in human immunodeficiency virus (HIV)-infected patients. DESIGN: Data were collected at 6-month intervals and analyzed to evaluate the association between alcohol dependence and consumption on depressive symptoms using longitudinal mixed-effects regression models controlling for specified covariates. MEASUREMENTS: The two independent variables were current alcohol dependence assessed using the Composite International Diagnostic Interview (CIDI) and past month consumption (heavy versus not heavy drinking) using a validated calendar-based method. The primary outcome was depressive symptoms as measured by the Center for Epidemiologic Studies Depression Scale (CES-D). PARTICIPANTS: HIV-infected adults with current or past alcohol problems. FINDINGS: Alcohol dependence and heavy alcohol use were significantly associated with higher CES-D scores in unadjusted models. In adjusted analyses, the association of current alcohol dependence persisted [mean difference in CES-D was 3.49 for dependence versus non-dependence; 95% confidence interval (CI): 1.76-5.22]; however, the effect of heavy drinking was no longer statistically significant (mean difference in CES-D was 1.04 for heavy versus not heavy drinking; 95% CI: -0.24-2.32). CONCLUSIONS: Alcohol use is associated with more depressive symptoms in HIV-infected patients with alcohol problems. This association remains significant after adjusting for potential confounders only when alcohol use meets the criteria for alcohol dependence.

Gender and non-medical use of prescription opioids: results from a national US survey.

AIMS: Gender differences exist regarding alcohol and illicit drug use disorders in the United States. Little is known about the gender-related factors associated with non-medical use of prescription opioids. DESIGN: Using data from the 2003 National Survey on Drug Use and Health, we examined risk factors for past-year non-medical use of prescription opioids stratified by gender. SETTING: Non-institutionalized US residences. Participants Civilian, non-institutionalized US citizens aged 12 years and older. MEASUREMENTS: Self-reported alcohol and drug use, focusing specifically on past-year non-medical use of prescription opioids. FINDINGS: Among 55 023 respondents, 4.8% reported past-year, non-medical use of prescription opioids. For both women and men, alcohol abuse/dependence and marijuana, hallucinogen, cocaine, non-medical stimulant and sedative/tranquilizer use were associated with past-year non-medical use of prescription opioids. Among women but not men, first use of illicit drugs beginning at 24 years or older [adjusted odds ratios (AOR) 1.90, 95% CI 1.05-3.44], serious mental illness (AOR 1.67, 95% CI 1.29-2.17) and cigarette smoking (AOR 1.33, 95% CI 1.05-1.68) were associated with past-year non-medical use of prescription opioids. Among men but not women, past-year inhalant use (AOR 1.93, 95% CI 1.28-2.92) was associated with the outcome. CONCLUSIONS: For both women and men, illicit drug use is associated with the non-medical use of prescription opioids. Additionally, certain factors associated with the non-medical use of prescription opioids are notably gender-specific. Clinicians should recognize that patients with a history of illicit substance use or misuse of other prescription medications are at increased risk for non-medical use of prescription opioids, and that gender-specific factors can help to identify individuals at greatest risk.

Non-medical use, abuse and dependence on prescription opioids among U.S. adults: psychiatric, medical and substance use correlates.

BACKGROUND: Non-medical use of prescription opioids carries risks including development of abuse/dependence. Such use may correlate with psychiatric, medical, and substance use characteristics. METHODS: Cross-sectional survey, the 2002-2004 National Survey on Drug Use and Health. Respondents 18 years and older (n=91,823). Bivariate and multivariable associations were investigated. RESULTS: The prevalence of past-year non-medical use of prescription opioids was 4.5%. Of those with non-medical use, 12.9% met criteria for abuse/dependence. On multivariable analysis, past-year non-medical use was associated with panic (AOR 1.2; 95% CI 1.04-1.5), depressive (AOR 1.2; 95% CI 1.01-1.5) and social phobic/agoraphobic symptoms (AOR 1.2; 95% CI 1.1-1.4). Among those with past-year non-medical prescription opioid use, those with abuse/dependence were more likely to have panic (AOR 1.7; 95% CI 1.2-2.4) and social phobic/agoraphobic symptoms (AOR 1.7; 95% CI 1.2-2.4). In addition, they were more likely to report fair/poor health (AOR 2.1; 95% CI 1.4-3.0), have misused another class of prescription medication (AOR 1.7; 95% CI 1.2-2.3), have used heroin (AOR 2.9; 95% CI 1.2-6.9) and initiated substance use before the age of 13 (AOR 4.7; 95% CI 1.1-19.9). CONCLUSIONS: Non-medical use of prescription opioids is common. Furthermore, nearly 13% of those with non-medical use meet criteria for abuse/dependence. Panic, social phobia and agoraphobia, low self-rated health status, and other substance misuse among those with non-medical use of prescription opioids should alert clinicians to screen for abuse and dependence.

Long-term treatment with buprenorphine/naloxone in primary care: results at 2-5 years.

To examine long-term outcomes with primary care office-based buprenorphine/naloxone treatment, we followed 53 opioid-dependent patients who had already demonstrated six months of documented clinical stability for 2-5 years. Primary outcomes were retention, illicit drug use, dose, satisfaction, serum transaminases, and adverse events. Thirty-eight percent of enrolled subjects were retained for two years. Ninety-one percent of urine samples had no evidence of opioid use, and patient satisfaction was high. Serum transaminases remained stable from baseline. No serious adverse events related to treatment occurred. We conclude that select opioid-dependent patients exhibit moderate levels of retention in primary care office-based treatment.

Buprenorphine/naloxone treatment in primary care is associated with decreased human immunodeficiency virus risk behaviors.

Methadone treatment reduces human immunodeficiency virus (HIV) risk, but the effects of primary-care-based buprenorphine/naloxone on HIV risk are unknown. The purpose of this study was to determine whether primary-care-based buprenorphine/naloxone was associated with decreased HIV risk behavior. We conducted a longitudinal analysis of 166 opioid-dependent persons (129 men and 37 women) receiving buprenorphine/naloxone treatment in a primary care clinic. We compared baseline and 12- and 24-week overall, drug-related, and sex-related HIV risk behaviors using the AIDS/HIV Risk Inventory (ARI). Buprenorphine/naloxone treatment was associated with significant reductions in overall and drug-related ARI scores from baseline to 12 and 24 weeks. Intravenous drug use in the past 3 months was endorsed by 37%, 12%, and 7% of patients at baseline and at 12 and 24 weeks, respectively (p< .001). Sex while you or your partner were "high" was endorsed by 64%, 13%, and 15% of patients at baseline and at 12 and 24 weeks, respectively (p< .001). Inconsistent condom use during sex with a steady partner was high at baseline and did not change over time. We conclude that primary-care-based buprenorphine/naloxone treatment is associated with decreased drug-related HIV risk, but additional efforts may be needed to address sex-related HIV risk when present.

Patient satisfaction with primary care office-based buprenorphine/naloxone treatment.

BACKGROUND: Factors associated with satisfaction among patients receiving primary care-based buprenorphine/naloxone are unknown. OBJECTIVE: To identify factors related to patient satisfaction in patients receiving primary care-based buprenorphine/naloxone that varied in counseling intensity (20 vs 45 minutes) and office visit frequency (weekly vs thrice weekly). DESIGN AND PARTICIPANTS: One hundred and forty-two opioid-dependent subjects. MEASUREMENTS: Demographics, drug treatment history, and substance use status at baseline and during treatment were collected. The primary outcome was patient satisfaction at 12 weeks. RESULTS: Patients' mean overall satisfaction score was 4.4 (out of 5). Patients were most satisfied with the medication and ancillary services and indicated strong willingness to refer a substance-abusing friend for the same treatment. Patients were least satisfied with their interactions with other opioid-dependent patients, referrals to Narcotics Anonymous, and the inconvenience of the treatment location. Female gender (beta = .17, P = .04) and non-White ethnicity/race (beta = .17, P = .04) independently predicted patient satisfaction. Patients who received briefer counseling and buprenorphine/naloxone dispensed weekly had greater satisfaction than those whose medication was dispensed thrice weekly (mean difference 4.9, 95% confidence interval 0.08 to 9.80, P = .03). CONCLUSIONS: Patients are satisfied with primary care office-based buprenorphine/naloxone. Providers should consider the identified barriers to patient satisfaction.
