Clinical Characteristics and Outcomes of Patients With Mpox Who Received Tecovirimat in a New York City Health System

Background

The 2022 global mpox outbreak was notable for transmission between persons outside of travel and zoonotic exposures and primarily through intimate contact. An understanding of the presentation of mpox in people with human immunodeficiency virus (HIV) and other immunocompromising conditions and knowledge of the efficacy of tecovirimat continue to evolve.

Methods

This retrospective study describes clinical features and outcomes of persons with mpox who received tecovirimat. Data were obtained via medical record review of patients prescribed tecovirimat in a health system in New York City during the height of the outbreak in 2022.

Results

One hundred thirty people received tecovirimat between 1 July and 1 October 2022. People with HIV (n = 80) experienced similar rates of recovery, bacterial superinfections, and hospitalization compared to patients without immunocompromising conditions. Individuals determined to be severely immunocompromised (n = 14) had a higher risk of hospitalization than those without severe immunocompromise (cohort inclusive of those with well-controlled HIV, excluding those without virologic suppression, n = 101): 50% versus 9% (P < .001). Hospitalized patients (n = 18 [13% of total]) were primarily admitted for bacterial superinfections (44.4%), with a median hospital stay of 4 days. Of those who completed follow-up (n = 85 [66%]), 97% had recovery of lesions at time of posttreatment assessment. Tecovirimat was well tolerated; there were no reported severe adverse events attributed to therapy.

Conclusions

There were no significant differences in outcomes between people with HIV when evaluated as a whole and patients without immunocompromising conditions. However, mpox infection was associated with higher rates of hospitalization in those with severe immunocompromise, including patients with HIV/AIDS. Treatment with tecovirimat was well tolerated.Key Points: In our mpox cohort, people with HIV had similar rates of recovery and complications as those without HIV or other immunocompromising conditions. Severe immunocompromise was associated with a higher hospitalization rate. Tecovirimat was well tolerated, with minimal side effects.

Attitudes Toward Peer-Delivered Sexual-Health Services Among New York City Sexual and Gender Minority Individuals Who Have Sex with Men and Attend Collective Sex Venues

Collective sex venues such as sex clubs are strategic sites to promote sexual health among sexual and gender minority individuals. We present qualitative findings from a multiple-method study on the acceptability of sexual-health services at collective sex venues in New York City (NYC) among attendees who identified as men, transgender, or gender non-conforming. In a survey used for sample selection (n = 342), most respondents (82.7%) agreed that "having outreach workers at sex venues is a good thing." Interviewees (n = 30) appreciated how on-site services could promote sexual health in their community. They felt peer workers should be familiar with collective sex venues and share demographic characteristics with attendees. Some participants felt workers should keep some boundaries from attendees, while others felt they could be fully integrated in the environment, suggesting that either peer outreach or popular-opinion leader types of interventions could be feasible.

The other side of screening: predictors of treatment and follow-up for anal precancers in a large health system

BACKGROUND

Anal cancer disproportionately affects people with HIV (PWH). High-grade squamous intraepithelial lesions (HSIL) are cancer precursors and treating them might prevent anal cancer. Data on adherence to HSIL treatment and surveillance is limited but needed to identify deficiencies of screening strategies.

METHODS

We collected data on high-resolution anoscopy (HRA) attendance and outcomes from 2009 to 2019 in a large urban anal cancer-screening program. Patients with an initial HSIL diagnosis were followed for return for HSIL electrocautery ablation within 6 months of index HSIL diagnosis, and follow-up HRA within 18 months of index HSIL diagnosis. We also evaluated predictors of these outcomes in univariable and multivariable analyses.

RESULTS

One thousand one hundred and seventy-nine unique patients with an anal HSIL diagnosis were identified and 684 (58%) returned for electrocautery ablation. Of those treated, only 174 (25%) and only 9% of untreated HSIL patients (47 of 495) underwent surveillance HRA within 18 months of index HSIL diagnosis. In multivariable analyses, black patients and PWH regardless of virologic control were less likely to undergo HSIL ablation within 6 months of HSIL diagnosis whereas patients with commercial insurance were more likely to be treated within 6 months of diagnosis. Among treated HSIL patients, PWH with viremia had a lower likelihood of engaging in post-treatment surveillance within 18 months of HSIL diagnosis.

DISCUSSION

Even in large specialized anal cancer screening programs adherence to HSIL treatment and surveillance is low. Psychosocial and economic determinants of health may impact retention in care. Addressing both personal and structural barriers to patient engagement may improve the effectiveness of anal cancer screening.

Comparing Anal Cancer Screening Algorithms Using Cytology and HPV DNA Testing in Three High-risk Populations

BACKGROUND

Screening strategies for high-risk human papillomavirus (hrHPV)-associated anal cancer are evolving. This study compares the screening performance of anal cytology to hrHPV DNA testing and two novel cytology/hrHPV cotesting algorithms among three high-risk populations.

METHODS

Anal cytology, hrHPV DNA testing, and high-resolution anoscopy (HRA)-guided biopsy results were analyzed from 1,837 participants comprising 1,504 HIV-infected men who have sex with men (MSM), 155 HIV-uninfected MSM, and 178 HIV-infected women. Screening performance to detect histological high-grade squamous intraepithelial lesions (HSIL)/cancer was compared between four strategies with distinct HRA referral thresholds: cytology (ASCUS); hrHPV testing (any hrHPV+); algorithm A (benign cytology/HPV16/18+ or ASCUS/hrHPV+); and algorithm B (benign or ASCUS cytology/hrHPV+).

RESULTS

Histological HSIL/cancer was detected in 756 (41%) participants. Cytology alone had the lowest sensitivity (0.76-0.89) but the highest specificity (0.33-0.36) overall and for each subgroup. Algorithm B was the most sensitive strategy overall (0.97) and for MSM (HIV-infected 0.97; HIV-uninfected 1.00). For HIV-infected women, hrHPV testing and both algorithms yielded higher sensitivity than cytology (0.96, 0.98, and 0.96). Specificity was low for all strategies and subgroups (range 0.16-0.36).

CONCLUSIONS

Screening algorithms that incoporate cytology and hrHPV testing significantly increased sensitivity and further decreased specificity to detect anal precancer/cancer among high-risk populations.

PrEP in the Real World: Predictors of 6-Month Retention in a Diverse Urban Cohort

The effectiveness of HIV pre-exposure prophylaxis (PrEP) depends on adherence, which requires retention in PrEP care. We sought to examine factors associated with six-month retention in PrEP care among individuals prescribed PrEP between 2011 and 2015 in a large, academic health system in the Bronx, New York. We used multivariable logistic regression to identify factors independently associated with six-month retention. Among 107 patients, retention at 6 months was 42%. In the multivariable analysis, heterosexual individuals were less likely to be retained in PrEP care at 6 months, but individuals who received prescriptions from attending physicians were more likely to be retained in care. Larger prospective studies are needed to better evaluate the individual and health system factors associated with long-term engagement in PrEP care.

Development and evaluation of a pilot overdose education and naloxone distribution program for hospitalized general medical patients

Background: Overdose education and naloxone distribution (OEND) to people at risk of witnessing or experiencing an opioid overdose has traditionally been provided through harm reduction agencies. Expanding OEND to inpatient general medical settings may reach at-risk individuals who do not access harm reduction services and have not been trained. An OEND program targeting inpatients was developed, piloted, and evaluated on 2 general medicine floors at Montefiore Medical Center, a large urban academic medical center in Bronx, New York. Methods: The planning committee consisted of 10 resident physicians and 2 faculty mentors. A consult service model was piloted, whereby the primary inpatient care team paged the consult team (consisting of rotating members from the planning committee) for any newly admitted patient who had used any opioid in the year prior to admission. Consult team members assessed patients for eligibility and provided OEND to eligible patients through a short video training. Upon completion, patients received a take-home naloxone kit. To evaluate the program, a retrospective chart review over the first year (April 2016 to March 2017) of the pilot was conducted. Results: Overall, consults on 80 patients were received. Of these, 74 were eligible and the consult team successfully trained 50 (68%). Current opioid analgesic use of ≥50 morphine milligram equivalents daily was the most common eligibility criterion met (38%). Twenty-four percent of patients were admitted for an opioid-related adverse event, the most common being opioid overdose (9%), then opioid withdrawal (8%), skin complication related to injecting (5%), and opioid intoxication (2%). Twenty-five percent had experienced an overdose, 35% had witnessed an overdose in their lifetime, and 83% had never received OEND previously. Conclusions: Integrating OEND into general inpatient medical care is possible and can reach high-risk patients who have not received OEND previously. Future research should identify the optimal way of implementing this service.

Awareness of post-exposure HIV prophylaxis in high-risk men who have sex with men in New York City

OBJECTIVES

To understand the factors associated with knowledge of non-occupational post-exposure prophylaxis (nPEP) and pre-exposure prophylaxis (PrEP), bathhouse patrons in New York City (NYC) were surveyed.

METHODS

554 men who have sex with men (MSM) at two NYC bathhouses were given a standardised survey focused on nPEP and PrEP at the time of HIV testing.

RESULTS

In the previous 90 days, 63% of respondents reported unprotected sex with a male partner and 7% reported any sex with a known HIV-positive male partner. Less than half reported having a primary provider (primary care practitioner) who was aware of their MSM behaviour. 201 men (36%) were aware of nPEP or PrEP. In univariate analyses, race/ethnicity, previous HIV testing, gay self-identification, higher education level, having a primary provider aware of MSM behaviour, reported interaction with the healthcare system, use of the internet for meeting sex partners, reporting unprotected sex in the previous 90 days, reporting any sex with an HIV-positive male partner in the previous 90 days and having a higher number of sex partners were each significantly associated with being aware of nPEP or PrEP. In multivariate analysis, having a higher number of sex partners was significantly associated (OR 5.10, p=0.02) with post-exposure prophylaxis (PEP)/PrEP knowledge and disclosure to a primary care provider was also associated, although less robustly (OR 2.10, p=0.06).

CONCLUSIONS

Knowledge of nPEP or PrEP among sexually active MSM in NYC is low and is associated with having a primary provider aware of their patient's same-sex behaviours. These findings show the need for improving education about nPEP among high-risk MSM in NYC and the role of providers in these efforts.

The Development and Implementation of an Outreach Program to Identify Acute and Recent HIV Infections in New York City

Introduction:

Since 2004, the authors have been operating First Call NYU, an outreach program to identify acute and recent HIV infections, also called primary HIV infections, among targeted at-risk communities in the New York City (NYC) metropolitan area.

Materials and Methodology:

First Call NYU employed mass media advertising campaigns, outreach to healthcare providers in NYC, and Internet-based efforts including search engine optimization (SEO) and Internet-based advertising to achieve these goals.

Results:

Between October 2004 and October 2008, 571 individuals were screened through this program, leading to 446 unique, in-person screening visits. 47 primary HIV infections, including 14 acute and 33 recent HIV infections, were identified.

Discussion:

Internet and traditional recruitment methods can be used to increase self-referrals for screening following possible exposure to HIV.

Conclusion:

Community education of at-risk groups, with the goal of increased self-diagnosis of possible acute HIV infection, may be a useful addition to traditional efforts to identify such individuals.

Implementation of HIV testing at 2 New York City bathhouses: from pilot to clinical service

BACKGROUND

Commercial sex venues (e.g., bathhouses) that cater to men who have sex with men (MSM) continue to function in most urban areas. These venues present a challenge to developing strategies to prevent the spread of the human immunodeficiency virus (HIV), but they also provide opportunities for interventions to reduce the risk and rate of disease transmission. Several cities in the United States have developed programs that offer HIV testing in these venues. Similar programs have not existed before in New York City.

METHODS

A pilot HIV testing program was implemented at 2 New York City bathhouses. Testing included rapid HIV testing, the use of the serologic testing algorithm for recent HIV seroconversion, and pooled plasma HIV viral load to detect and date incident and acute HIV infections. In addition to HIV tests, behavioral and demographic data were collected from 493 presumed HIV-negative participants.

RESULTS

The pilot program recruited MSM who were at high risk for HIV infection. Of the 493 men tested, 20 (4%) were found to be positive for HIV, and 8 (40%) of these 20 men demonstrated evidence of acute or recent HIV infection. The program tested men often not tested in more traditional medical settings. Significant disparities were demonstrated in the testing habits of MSM who reported having sex with women and had not disclosed same-sex activities to their caregivers.

CONCLUSIONS

Bathhouse-based testing for HIV infection can be implemented in New York City and would include a population of MSM who are at high risk for HIV infection. Because of the high rate of recent HIV infection, expanded testing in these venues may be a good strategy to reduce the forward transmission of HIV in this highly sexually active population.

Endocrine and metabolic abnormalities involved in obesity associated with typical antipsychotic drug administration

In this study, the authors assessed the endocrine system and glucose tolerance in obese and non-obese women chronically treated with typical antipsychotic drugs (AP). In particular, we tested the hypotheses that these subjects display hypogonadism and increased insulin resistance compared to healthy weight-matched controls, as these abnormalities create a tendency towards excessive body weight gain. Twenty-six AP-treated women were matched with 26 healthy women by age, body mass index and day of the menstrual cycle. The following serum variables were evaluated in each subject: glucose tolerance after an oral glucose overload, insulin, leptin, beta-endorphin, reproductive hormones, adrenal steroids and lipids. Compared to controls, AP-treated women displayed significantly higher levels of basal glucose, insulin after 60 min of the glucose overload, prolactin, thyroid stimulating hormone and beta-endorphin, with lower levels of C-Peptide, progesterone, 17-OH progesterone, androstenedione and high-density lipoprotein cholesterol. The levels of estradiol, estrone and leptin did not differ between the groups. Thus, women treated with typical AP appeared to display more insulin resistance than healthy controls, predisposing them to excessive weight gain. Insulin sensitivity might be further impaired when the subject switches to atypical AP administration. Metformin and related agents may reduce body weight in these subjects. The high levels of the opiate beta-endorphin suggest that opiate antagonists such as naloxone and naltrexone might be useful as well. Even though the luteal phase of the menstrual cycle appears to be severely disturbed, the normal serum levels of estradiol and estrone do not support the proposal derived from animal experimental studies about the use of estrogens or tamoxifen to counteract AP-induced obesity.

Body weight gain after administration of antipsychotic drugs: correlation with leptin, insulin and reproductive hormones

Excessive body weight gain, hyperprolactinemia and low gonadal steroid serum levels are often observed during chronic administration of antipsychotic drugs (AP). Clinical and experimental findings suggest that leptin, the peptidic hormone involved in long-term body weight regulation, and reproductive hormones are interrelated. Therefore, we assessed circulating leptin levels in healthy, lean women (n = 12) and men (n = 7) before and after short-term administration of the AP sulpiride (SUL, 200 mg/day). In addition, we studied psychotic obese (n = 9) and lean women (n = 13) under chronic treatment with diverse AP. No significant weight changes were observed after SUL administration in healthy women--initial weight: 54.9+/-2.6 Kg; final weight: 55.04+/-2.6, NS. Leptin levels did not change either: 11.9+/-1.5 ng/ml. vs. 10.6+/-1.3, NS. By contrast, a small, but significant weight gain was found in SUL-treated men--60.6+/-1.9 Kg. vs. 61.3+/-2.1, p = 0.004. Leptin and insulin levels were significantly higher after SUL administration--leptin: 2.77+/-0.22 ng/ml. vs. 13.9+/-2.5, p=0.035; insulin: 3.59+/-0.17 mIU/ml vs. 8.81+/-0.81, p = 0.0001. In these subjects, leptin levels positively correlated with body weight change (p = 0.006), and serum prolactin change (p = 0.001). Obese psychotic women (Body Mass Index, BMI, Kg/m2 = 31.5+/-1.03) displayed higher leptin levels than non-obese psychotic women (BMI = 25.5+/-0.52): 26.8+/-4.8, vs. 12.8+/-3.4 ng/ml, p = 0.006. In these women, a significant positive correlation was found between leptin levels and BMI (p = 0.0001), and between leptin and basal insulin levels (p = 0.001). These results show that the expected circulating leptin elevation which is observed when body weight raises, is preserved in people treated with AP drugs.
