HIV testing at a community health center before and after implementing universal screening.

This study analyzed the quality of HIV screening at one of the largest community health centers in Connecticut. The data indicated that implementing universal HIV screening increased the proportion of underrepresented minorities and women tested, reducing the HIV testing disparities that previously existed at this center.

Improvements in health-related quality of life among methadone maintenance clients in Dar es Salaam, Tanzania.

Background: Injection of heroin has become widespread in Dar es Salaam, Tanzania and is spreading throughout the country. To prevent potential bridging of HIV epidemics, the Tanzanian government established a methadone maintenance treatment (MMT) clinic in February 2011. We assess the effect of MMT on health-related quality of life (HRQOL) and examine factors, particularly HIV infection and methadone dose, associated with changes in HRQOL.

The Impact of Enhanced Screening and Treatment on Hepatitis C in the United States.

Background: The effectiveness of interferon-free direct-acting antivirals (DAA) in treating chronic hepatitis C virus (HCV) is limited by low screening and treatment rates, particularly among people who inject drugs (PWIDs).

Methods: To evaluate the levels of screening and treatment with interferon-free DAAs that are required to control HCV incidence and HCV-associated morbidity and mortality, we developed a transmission model, stratified by age and by injection drug use, and calibrated it to epidemiological data in the United States from 1992 to 2014. We quantified the impact of administration of DAAs at current and at enhanced screening and treatment rates, focusing on outcomes of HCV incidence, prevalence, compensated and decompensated cirrhosis, hepatocellular carcinoma, liver transplants, and mortality from 2015 to 2040.

Novel Alleles of gon-2, a C. elegans Ortholog of Mammalian TRPM6 and TRPM7, Obtained by Genetic Reversion Screens.

TRP (Transient Receptor Potential) cation channels of the TRPM subfamily have been found to be critically important for the regulation of Mg2+ homeostasis in both protostomes (e.g., the nematode, C.

Implementation and Operational Research: Linkage to Care Among Methadone Clients Living With HIV in Dar es Salaam, Tanzania.

Background: The first methadone maintenance treatment clinic in Tanzania was launched in February 2011 to address an emerging HIV epidemic among people who inject drugs. We conducted a retrospective cohort study to understand factors associated with linkage to HIV care and explore how a methadone maintenance treatment clinic can serve as a platform for integrated HIV care and treatment.

Methods: This study used routine programmatic and clinical data on clients enrolled in methadone at Muhimbili National Hospital from February 2011 to January 2013.

The pharmacokinetic and pharmacodynamic interactions between buprenorphine/naloxone and elvitegravir/cobicistat in subjects receiving chronic buprenorphine/naloxone treatment.

Background: Interactions between HIV and opioid-dependence therapies are known to occur. We sought to determine if such interactions occurred between buprenorphine/naloxone and elvitegravir boosted with cobicistat.

Methods: We performed a within-subject open-labeled pharmacokinetic and pharmacodynamic study in 17 HIV-seronegative subjects stabilized on at least 2 weeks of buprenorphine/naloxone therapy.

Testing an optimized community-based human immunodeficiency virus (HIV) risk reduction and antiretroviral adherence intervention for HIV-infected injection drug users.

The authors conducted a preliminary study of the 4-session Holistic Health for HIV (3H+), which was adapted from a 12-session evidence-based risk reduction and antiretroviral adherence intervention. Improvements were found in the behavioral skills required to properly adhere to HIV medication regimens. Enhancements were found in all measured aspects of sex-risk reduction outcomes, including HIV knowledge, motivation to reduce sex-risk behavior, behavioral skills related to engaging in reduced sexual risk, and reduced risk behavior.

Pharmacokinetic drug interactions and adverse consequences between psychotropic medications and pharmacotherapy for the treatment of opioid dependence.

Background: Psychiatric comorbidities among opioid-dependent patients are common. Many medications used to treat both conditions are metabolized through complimentary cytochrome P450 isoenzymes. When medication-assisted treatment for opioid dependence is concurrently used with psychotropic medications, problematic pharmacokinetic drug interactions may occur.

Pharmacokinetic interactions between buprenorphine/naloxone and once-daily lopinavir/ritonavir.

Background: This study was conducted to examine the pharmacokinetic interactions between buprenorphine/naloxone (BUP/NLX) and lopinavir/ritonavir (LPV/r) in HIV-seronegative subjects chronically maintained on BUP/NLX.

Methods: This study was an open labeled pharmacokinetic study in twelve HIV-seronegative subjects stabilized on at least 3 weeks of BUP/NLX therapy. Subjects sequentially underwent baseline and steady-state pharmacokinetic evaluation of once-daily LPV/r (800/200 mg).

Persistence of virological benefits following directly administered antiretroviral therapy among drug users: results from a randomized controlled trial.

Background: Although directly administered antiretroviral therapy (DAART) has demonstrated impressive biological benefits compared with self-administered therapy (SAT) among drug users, the persistence of DAART after transition to SAT has not been examined.

Methods: We conducted a community-based, prospective, randomized controlled trial of 6 months of DAART compared with SAT. The primary outcome was the proportion of subjects who achieved virological success at 6 months postintervention, defined as either a 1.

Clinical outcomes of hepatitis C treatment in a prison setting: feasibility and effectiveness for challenging treatment populations.

Background: More than one-third of people in the United States with hepatic C virus (HCV) infection pass through the correctional system annually. Data are lacking on outcomes of treatment with pegylated interferon plus ribavirin (PEG-RBV) in correctional settings.

Methods: During 2002-2006, we analyzed patients in the Connecticut Department of Correction who received PEG-RBV.

A pilot survey of attitudes and knowledge about opioid substitution therapy for HIV-infected prisoners.

A majority of inmates in the state of Connecticut Department of Corrections use opioids or are opioid dependent before incarceration. None of the state's prisons offer opioid substitution therapy other than for detoxification or maintenance therapy for women during pregnancy. On release to the community, most prisoners relapse to drug use and this has been associated with higher recidivism rates, and less adherence to antiretroviral medications for HIV-infected persons.

Estimating GFR using serum cystatin C alone and in combination with serum creatinine: a pooled analysis of 3,418 individuals with CKD.

Background: Serum cystatin C was proposed as a potential replacement for serum creatinine in glomerular filtration rate (GFR) estimation. We report the development and evaluation of GFR-estimating equations using serum cystatin C alone and serum cystatin C, serum creatinine, or both with demographic variables.

Study Design: Test of diagnostic accuracy.

Case series on the safe use of buprenorphine/naloxone in individuals with acute hepatitis C infection and abnormal hepatic liver transaminases.

Background: Hepatitis C virus (HCV) is the most prevalent chronic viral illness in the United States. Many individuals with virus HCV are opioid dependent requiring treatment with opiate substitution treatment such as buprenorphine. Previous reports in the literature have suggested hepatotoxicity with buprenorphine tempering initial enthusiasm of the safety of buprenorphine in HCV-infected patients.

Initial strategies for integrating buprenorphine into HIV care settings in the United States.

The Centers for Disease Control and Prevention's HIV Prevention Strategic Plan Through 2005 advocated for increasing the proportion of persons with human immunodeficiency virus (HIV) infection and in need of substance abuse treatment who are successfully linked to services for these 2 conditions. There is evidence that integrating care for HIV infection and substance abuse optimizes outcomes for patients with both disorders. Buprenorphine, a recently approved medication for the treatment of opioid dependence in physicians' offices, provides the opportunity to integrate the treatment of HIV infection and substance abuse in one clinical setting, yet little information exists on the models of care that will most successfully facilitate this integration.

Adherence to hepatitis B virus vaccination at syringe exchange sites.

Injection drug users (IDUs) are at high risk for hepatitis B virus (HBV); however, they often do not receive preventive vaccination. IDUs who use mobile health care services linked to a syringe exchange program in New Haven were routinely screened for HBV, hepatitis C virus, and syphilis. Individuals without prior exposure to HBV were offered three-part vaccination series.

Developing a directly administered antiretroviral therapy intervention for HIV-infected drug users: implications for program replication.

Directly administered antiretroviral therapy (DAART) is one approach to improving adherence to among human immunodeficiency virus (HIV)-infected drug users. We evaluated the essential features of a community-based DAART intervention in a randomized, controlled trial of DAART versus self-administered therapy. Of the initial 72 subjects, 78% were racial minorities, and 32% were women.
