Public health detailing to increase naloxone access in NYC pharmacies.

Background: Drug overdose is a public health crisis in the United States. Opioid overdose deaths are preventable using naloxone, an opioid antagonist that reverses the effect of an opioid and prevents fatal overdose.

Objectives: This study aimed to evaluate changes in naloxone standing order status, attitudes, and practice behavior after an 8-week public health detailing campaign on increasing naloxone access conducted among pharmacists in independent pharmacies in New York City (NYC).

Costs of opioid overdose education and naloxone distribution in New York City.

Naloxone is an opioid antagonist medication that can be administered by lay people or medical professionals to reverse opioid overdoses and reduce overdose mortality. Cost was identified as a potential barrier to providing expanded overdose education and naloxone distribution (OEND) in New York City (NYC) in 2017. We estimated the cost of delivering OEND for different types of opioid overdose prevention programs (OOPPs) in NYC.

Hepatitis C Treatment Outcomes for People Who Inject Drugs Treated in an Accessible Care Program Located at a Syringe Service Program.

Hepatitis C virus (HCV) is a significant public health problem that disproportionately afflicts people who inject drugs. We describe outcomes of HCV treatment co-located within a syringe services program (SSP). Fifty-three participants started therapy, and 91% achieved sustained virologic response.

Witnessed overdoses and naloxone use among visitors to Rikers Island jails trained in overdose rescue.

With the opioid overdose mortality rates rising nationally, The New York City Department of Health and Mental Hygiene (NYC DOHMH) has worked to expand overdose rescue training (ORT) and naloxone distribution. This study sought to determine rates of overdose witnessing and naloxone use among overdose rescue-trained visitors to the NYC jails on Rikers Island. We conducted a six-month prospective study of visitors to NYC jails on Rikers Island who received ORT.

Risk factors for hepatitis C seropositivity among young people who inject drugs in New York City: Implications for prevention.

Background: Hepatitis C virus (HCV) infection remains a significant problem in the United States, with people who inject drugs (PWID) disproportionately afflicted. Over the last decade rates of heroin use have more than doubled, with young persons (18-25 years) demonstrating the largest increase.

Methods: We conducted a cross-sectional study in New York City from 2005 to 2012 among young people who injected illicit drugs, and were age 18 to 35 or had injected drugs for ≤5 years, to examine potentially modifiable factors associated with HCV among young adults who began injecting during the era of syringe services.

Can hepatitis C be eradicated in the United States?

The advent of highly effective antiviral regimens will make the eradication of hepatitis C in high-income countries such as the United States technically feasible. But eradicating hepatitis C will require escalating our response to the epidemic in key domains, including surveillance and epidemiology, prevention, screening, care and treatment, policy, research, and advocacy. Surveillance must be nimble enough to quickly assess the magnitude of new transmission patterns as they emerge.

Spontaneous clearance of chronic hepatitis C virus infection is associated with appearance of neutralizing antibodies and reversal of T-cell exhaustion.

Background: Hepatitis C virus (HCV) readily establishes chronic infection with exhaustion of HCV-specific T cells and escape from neutralizing antibodies. Spontaneous recovery from chronic infection is rare and has never to our knowledge been studied immunologically.

Methods: We prospectively studied, from prior to infection through >2 years of follow-up, cytokines, HCV-specific T cells, and antibodies, as well as viral sequence evolution in a white male who spontaneously cleared HCV genotype 1a after 65 weeks.

Induction of CXCR3- and CCR5-associated chemokines during acute hepatitis C virus infection.

Background & Aims: Characterization of inflammatory mediators, such as chemokines, during acute hepatitis C virus (HCV) infection might shed some light on viral clearance mechanisms.

Methods: Plasma levels of CXCR3 (CXCL9-11)- and CCR5 (CCL3-4)-associated chemokines, ALT, and HCV RNA were measured in nine injection drug users (median 26 samples/patient) before and during 10 acute (eight primary and two secondary) HCV infections. Using functional data analysis, we estimated smooth long-term trends in chemokine expression levels to obtain the magnitude and timing of overall changes.
