Taking an Alternative Approach to Drug Delivery

Increased awareness of the carbon footprint associated with pharmaceutical products and the replacement of high global warming potential (GWP) constituents used in the final product, or within the manufacturing process, may drive further diversification of formulation approaches in the future. [...]the nose offers an opportunity to deliver drugs directly to the brain or central nervous system (CNS) via the olfactory pathway. Two relatively recent commercializations for intranasal delivery are naloxone nasal spray to treat suspected opioid overdose emergencies and diazepam nasal spray for short term rescue treatment of seizure clusters. [...]in cystic fibrosis, the overproduction of mucus and alteration of mucus properties, represents a challenge for effective drug delivery by inhalation alone.

A Descriptive Study on Opioid Misuse Prevalence and Office-Based Buprenorphine Access in Ohio Prior to the Removal of the Drug Addiction Treatment Act of 2000 Waiver.

Background Medications for the treatment of opioid use disorder (MOUD) are effective evidence-based strategies to reduce opioid overdose deaths. Strategies to optimize MOUD availability and uptake are needed. Objective We aim to describe the spatial relationship between the estimated prevalence of opioid misuse and office-based buprenorphine access in the state of Ohio prior to the removal of the Drug Addiction Treatment Act of 2000 (DATA 2000) waiver requirement. Methods We conducted a descriptive ecological study of county-level (N=88) opioid misuse prevalence and office-based buprenorphine prescribing access in Ohio in 2018. Counties were categorized into urban (with and without a major metropolitan area) and rural. The county-level prevalence estimates of opioid misuse per 100,000 were derived from integrated abundance modeling. Utilizing data from the Ohio Department of Mental Health and Addiction Services, as well as the state's Physician Drug Monitoring Program (PDMP), buprenorphine access per 100,000 was estimated by the number of patients in each county that could be served by office-based buprenorphine (prescribing capacity) and the number of patients served by office-based buprenorphine (prescribing frequency) for opioid use disorder. The ratios of opioid misuse prevalence to both prescribing capacity and frequency were calculated by county and mapped. Results Less than half of the 1,828 waivered providers in the state of Ohio in 2018 were prescribing buprenorphine, and 25% of counties had no buprenorphine access. The median estimated opioid misuse prevalence and buprenorphine prescribing capacity per 100,000 were highest in urban counties, particularly those with a major metropolitan area. Although the median estimated opioid misuse prevalence was lower in rural counties, all counties in the highest quartile of estimated misuse prevalence were rural. In addition, the median buprenorphine prescribing frequency was highest in rural counties. While the ratio of opioid misuse prevalence to buprenorphine prescribing capacity was lowest in urban counties, the ratio of opioid misuse prevalence to buprenorphine prescribing frequency was lowest in rural counties. Opioid misuse prevalence and buprenorphine prescribing frequency demonstrated similar spatial patterns, with highest levels in the southern and eastern portions of the state, while office-based buprenorphine prescribing capacity did not. Conclusion Urban counties had higher buprenorphine capacity relative to their burden of opioid misuse; however, access was limited by buprenorphine prescribing frequency. In contrast, in rural counties, a minimal gap was evident between prescribing capacity and frequency, suggesting that buprenorphine prescribing capacity was the major factor limiting access. While the recent deregulation of buprenorphine prescribing should help improve buprenorphine access, future research should investigate whether deregulation similarly impacts buprenorphine prescribing capacity and buprenorphine prescribing frequency.

The impact of the implementation of medication for opioid use disorder and COVID-19 in a statewide correctional system on treatment engagement, postrelease continuation of care, and overdose.

BACKGROUND: People with opioid use disorder (OUD) are overrepresented in US correctional facilities and experience disproportionately high risk for overdose after release. Medications for OUD (MOUD) are highly efficacious but not available to most incarcerated individuals. In 2018, Vermont began providing MOUD for all incarcerated individuals with OUD statewide. In 2020, the COVID-19 state of emergency began. We assessed the impact of both events on MOUD utilization and treatment outcomes. METHODOLOGY: Analyses linked Vermont Department of Corrections administrative data and Medicaid claims data between 07/01/2017 and 03/31/2021. The study used logistic regression to analyze treatment engagement among all incarcerated individuals in Vermont. Multilevel modeling assessed change in clinical outcomes among release episodes that occurred among individuals with an OUD diagnosis Medicaid claim. RESULTS: Prescriptions for MOUD while incarcerated increased from 0.8% to 33.9% of the incarcerated population after MOUD implementation (OR = 67.4) and subsequently decreased with the onset of COVID-19 to 26.6% (OR = 0.7). After MOUD implementation, most prescriptions (63.1%) were to individuals who had not been receiving MOUD prior to incarceration, but this figure decreased to 53.9% with the onset of COVID-19 (OR = 0.7). Prescriptions for MOUD within 30 days after release increased from 33.9% of those with OUD before to 41.0% after MOUD implementation (OR = 1.4) but decreased to 35.6% with the onset of COVID-19 (OR = 0.8). Simultaneously, opioid-related nonfatal overdoses within 30 days after release decreased from 1.2% before to 0.8% after statewide MOUD implementation (OR = 0.3) but increased to 1.9% during COVID-19 (OR = 3.4). Fatal overdoses within 1 year after release decreased from 27 deaths before to ≤10 after statewide MOUD implementation and remained ≤10 during COVID-19. CONCLUSIONS: This longitudinal evaluation demonstrated increased treatment engagement and a decrease in opioid-related overdose following implementation of MOUD in a statewide correctional system. In contrast, these improvements were somewhat attenuated with the onset of COVID-19, which was associated with decreased treatment engagement and an increase in nonfatal overdoses. Considered together, these findings demonstrate the benefits of statewide MOUD for incarcerated individuals as well as the need to identify and address barriers to continuation of care following release from incarceration in the context of COVID-19.

Non-fatal drug overdose among persons who inject drugs during first two years of the COVID-19 pandemic in New York City: Prevalence, risk factors.

Background: We examined non-fatal drug overdoses during the COVID-19 pandemic among persons who inject drugs (PWID) in New York City (NYC). Methods: We recruited 275 PWID through respondent driven sampling and staff outreach from Oct. 2021-Sept. 2022 and enrolled in a cross-sectional survey. Information was collected on demographics, drug use behaviors, overdose experiences, substance use treatment history and strategies for coping with overdose threat. We compared PWID who did and did not experience non-fatal overdoses during lifetime and during the COVID-19 pandemic. Results: Participants were 71% male, and the mean age was 49 (SD 10). Heroin was the most frequently reported drug used (79%), 82% were fentanyl positive at enrollment urinalysis, 60% had overdosed in their lifetime and 34% had overdosed during the COVID-19 pandemic. In multivariable logistic regression, having previous overdosed, having a received a psychiatric diagnosis, and having a regular group of injectors were independently associated with experiencing an overdose during the pandemic. Overdose during the pandemic was unexpectedly high (approximately 30%) among persons reporting less than daily use of their main drug. Among PWID, 95% reported practicing at least one and 75% at least two overdose coping strategies. Practicing the different strategies, however, was generally not associated with a lower probability of experiencing an overdose. Conclusions: There has been a high rate of non-fatal overdoses among PWID in NYC during the pandemic. Fentanyl is almost ubiquitous in the drug supply in the city. PWID coping strategies are not yet providing strong protective effects against non-fatal overdose.

Opioid use in the era of COVID-19: a multifaceted study of the opioid epidemic in Canada.

Introduction: The COVID-19 pandemic has had wide economic, social, and health impacts, and has disproportionately affected individuals who were already vulnerable. Individuals who use opioids have dealt with evolving public health measures and disruptions while also dealing with the ongoing opioid epidemic. Opioid-related mortalities in Canada increased throughout the COVID-19 pandemic, but it is unclear to what extent public health measures and the progression of the pandemic contributed to opioid-related harms. Methods: To address this gap, we used emergency room (ER) visits recorded in the National Ambulatory Care Reporting System (NACRS) between 1 April 2017, and 31 December 2021, to investigate trends of opioid-related harms throughout the pandemic. This study also included semi-structured interviews with service providers in the field of opioid use treatment, to help contextualize the trends seen in ER visits and offer perspectives on how opioid use and services have changed throughout the COVID-19 pandemic. Results: Overall, the number of hospitalizations related to an opioid use disorder (OUD) decreased with progressing waves of the pandemic and with increasing severity of public health measures in Ontario. The rate of hospitalizations related to opioid poisonings (e.g., central nervous system and respiratory system depression caused by opioids) significantly increased with the progressing waves of the pandemic, as well as with increasing severity of public health measures in Ontario. Discussion: The increase in opioid-related poisonings is reflected in the existing literature whereas the decrease in OUDs is not. Moreover, the increase in opioid-related poisonings aligns with the observations of service providers, whereas the decrease in OUD contradicts the trends that service providers described. This discrepancy could be explained by factors identified by service providers, including the pressures on ERs during the pandemic, hesitancy to seek treatment, and drug toxicity.

Clostridium Difficillae Infection in Post-Covid Patients

Intro: The ongoing pandemic caused by the SARS-CoV-2 virus has brought many new insights into medicine. During the first months of the pandemic, when there were no comprehensive guidelines for precise antimicrobial therapy, empirical overuse of broad-spectrum antibiotics was observed. Which resulted in the development of clostidium infection in certain cases. In our report, we address 83 cases of clostridial colitis in post-covid patients from 3/2020 to 3/2021 and their specific therapy. Method(s): Retrospective analysis of risk factors for clostridial infection and therapy of clostridial colitis. Finding(s): In the period 3/2020-3/2021, 9617 patients were diagnosed with SARS-CoV-2 virus infection in our hospital, of which 1247 were hospitalized. In 83 cases, clostridial colitis occurred during or after the covid infection had resolved. Mortality in this group was 17%, which corresponds to 14 patients. Previous empirical administered antiobiotics in COVID-19 infection contributed to the development of clostridial colitis in case of 22 patients (27%) by clarithromycin, in 14 pacients (17%) by penicillins and by 3rd generation cephalosporins in 9 patients (11%). The average duration of therapy with broad-spectrum antibiotics was 15.63 days (+-8.99). Other risk factors we observed are: PPI use (25%), active malignant disease (10%), previous glucocorticoid therapy (22%). Vancomycin was used in clostridial infection therapy in 47% (39), metronidazole in 31% (25) and fidaxonicin in 7% (6). In the group, we observed recurrence of clostridium difficile infection in 14% of patients and FMT was performed in 6 patients. Conclusion(s): This study shows a higher percentage of clostridial infection in cases of long-term therapy with broad-spectrum antibiotics. It also points to the effect of specific antimicrobial therapy for infection caused by the bacterium Clostridium difficile and the possibility of using fecal bacteriotherapy.Copyright © 2023

A Case Report of Ivermectin-Induced Liver Failure

Introduction: Ivermectin is an antiparasitic medication that is primarily metabolized by the liver. During the COVID-19 pandemic, researchers demonstrated that Ivermectin successfully inhibited the replication of SARS-COV-2 in vivo, but current research has failed to demonstrate clinical benefit for treatment of COVID-19. Despite this, misinformation campaigns have misled patients to ingest Ivermectin at concentrations meant for domestic animals. Here, we present a case of acute liver failure secondary to the use of Ivermectin. Case Description/Methods: A 61-year-old man with medical history of ischemic cardiomyopathy with last echocardiogram showing ejection fraction at 21%, atrial fibrillation on warfarin for oral anticoagulation, and previously treated Hepatitis C presented with generalized weakness and yellowish discoloration of the skin worsening over the last two weeks. The patient denied significant alcohol use, acetaminophen use, or illicit drugs. He admitted to injecting himself with two doses of weight-based horse ivermectin, for COVID prophylaxis, two weeks prior to his presentation. Physical exam was pertinent for scleral icterus and hepatomegaly with no abdominal tenderness. Initial labs revealed elevated liver chemistries in a mixed pattern (Figure 1). Acute hepatitis panel, HSV, and CMV were negative. Hepatitis C antibodies were positive, but the patient was in sustained virologic response. Full workup for chronic liver disease was unremarkable. Ultrasound revealed hepatosplenomegaly with patent portal and hepatic vasculature. Subsequently, the patient developed hepatic encephalopathy along with his coagulopathy, raising concern for acute hepatic failure. The patient was transferred to the ICU and started on NAcetylcysteine, rifaximin, and supportive care. The patient recovered well and fortunately did not require liver transplant. Discussion(s): While the FDA recommends against the use of Ivermectin for COVID-19, many continue to inappropriately consume it. Ivermectin-induced liver failure is a rare but deadly side effect. Given our patient's rapid onset of symptoms post-self injection of Ivermectin, his liver injury was presumed to be related to Ivermectin. The drug interaction between Ivermectin and warfarin had worsened the patients coagulopathy. Physicians should be aware of the ways Ivermectin overdose may clinically present to avoid delayed treatment. This case demonstrates the detriments of perpetuation of medical misinformation to care.

A Case of Primary Biliary Cirrhosis With New Onset Hyperthyroidism and Supratherapeutic INR

Introduction: Hyperthyroidism is known to increase catabolism of vitamin-K-dependent clotting factors (II, VII, IX, X) and increase the response of vitamin K antagonists, usually warfarin. Primary biliary cirrhosis (PBC) has been associated with thyroid dysfunction (TD), especially with autoimmune thyroid disease. In the below case, a patient with known PBC on warfarin is found to have severely elevated INR related to new-onset hyperthyroidism with clinical consequences of hemorrhage including upper GI bleed. Case Description/Methods: A 64-year-old female with PBC and antiphospholipid antibody syndrome on warfarin was admitted for hemorrhagic epiglottitis requiring emergency intubation and supratherapeutic INR. Her PBC was diagnosed as stage II on biopsy 23 years ago and has remained clinically stable on ursodiol therapy. On presentation, the patient was tachycardic, tachypneic, and had O2 saturations <90% on HFNC prior to intubation. Physical exam significant for larger goiter with diffuse upper airway swelling. She was admitted and found to have COVID-19 infection, INR .16.0 and PT>200.0 (limit of lab), WBC of 22.8, and lactate of 2.5. LFTs WNL aside from albumin of 2.0. TSH was <0.0017 (limit of lab) and free T4 of 3.4, free T3 of 5.3. TSH receptor antibody (TRAB) and thyroid stimulating immunoglobulin (TSI) levels were normal. Her last TSH was normal a year ago. CTA chest found a 5.7cm heterogeneous, partially calcified superior mediastinal mass consistent with multinodular thyroid goiter. Patient was initially given prothrombin complex concentrate and vitamin K with correction of INR over the following few days. She was extubated and started on methimazole. During the hospital course, she was found to have coffee ground emesis for which an EGD was done with findings of non-bleeding gastric ulcer (Forrest Class IIc) and LA Grade D esophagitis with adherent clot and bleeding for which hemostatic spray was applied. Patient was discharged a few days later following resumption of warfarin and on pantoprazole and methimazole. Discussion(s): The above case demonstrates a rare case of PBC and new-onset hyperthyroidism due to multinodular thyroid goiter causing significantly elevated INR in the setting of warfarin use with hospital course complicated by GI bleed. PBC is associated with TD - hyperthyroidism, hypothyroidism, and thyroid cancer. Hyperthyroidism is less commonly associated with PBC compared to other TDs but should be considered especially with a finding of elevated INR.

Community partner perspectives on the implementation of a novel safer supply program in Canada: a qualitative study of the MySafe Project.

BACKGROUND: The adulteration of the illicit drug supply with fentanyl and its analogues is driving the ongoing overdose crisis in North America. While various harm reduction interventions address overdose-related risks, there is growing interest in safer supply programs, including the MySafe Project which utilizes a biometric dispensing machine that provides pharmaceutical opioid alternatives to the toxic drug supply. However, the experiences and perspectives of professional community partners on program implementation remain unexplored. This study aims to examine professional community partner perspectives on the feasibility, as well as barriers and facilitators to the implementation of the MySafe program. METHODS: Semi-structured qualitative interviews were conducted with 17 professional community partners involved in program implementation across four pilot locations in Canada. Thematic analysis of interviews focused on perspectives on safer supply, barriers and facilitators faced during program implementation, and recommendations to inform future scale-up of low-barrier safer supply models across Canada. RESULTS: Participants identified a variety of barriers, including the dependence on clinician buy-in, coupled with regulatory and logistical constraints. In addition, some participants perceived hydromorphone to be an inadequate substitute to the increasingly toxic street opioid supply. Lastly, technical difficulties were described as barriers to service uptake and delivery. Conversely, having political and community buy-in, availability of wrap-around services, and collaborative communication from the MySafe team served as facilitators to program implementation. Though community partners preferred establishing MySafe machines into existing community organizations, they also discussed benefits of housing-based MySafe programs. The potential role of this program in mid-sized to rural cities was also emphasized. CONCLUSIONS: To address the overdose crisis, there is an urgent need to implement and evaluate novel solutions that address supply drivers of crisis. Community partner-informed research plays an integral role in ensuring program acceptability and proper implementation. Our findings identify current gaps and facilitators underlying the efficacy of one such model, together with future directions for improvement. Participant recommendations included a diversification of medications offered and types of locations for MySafe programs, a streamlined national approach to prescribing guidelines coupled with more robust training for healthcare professionals, and an emphasis on service delivery within an integrated services model. Our findings underscore a potential gap between the goals of healthcare providers in ensuring comprehensive care and the necessity for low-barrier models such as MySafe that can function both within and outside of integrated service models.

Considerations for the design of overdose education and naloxone distribution interventions: results of a multi-stakeholder workshop.

INTRODUCTION: Opioid overdose epidemic is a public health crisis that is impacting communities around the world. Overdose education and naloxone distribution programs equip and train lay people to respond in the event of an overdose. We aimed to understand factors to consider for the design of naloxone distribution programs in point-of-care settings from the point of view of community stakeholders. METHODS: We hosted a multi-stakeholder co-design workshop to elicit suggestions for a naloxone distribution program. We recruited people with lived experience of opioid overdose, community representatives, and other stakeholders from family practice, emergency medicine, addictions medicine, and public health to participate in a full-day facilitated co-design discussion wherein large and small group discussions were audio-recorded, transcribed and analysed using thematic approaches. RESULTS: A total of twenty-four participants participated in the multi-stakeholder workshop from five stakeholder groups including geographic and setting diversity. Collaborative dialogue and shared storytelling revealed seven considerations for the design of naloxone distribution programs specific to training needs and the provision of naloxone, these are: recognizing overdose, how much naloxone, impact of stigma, legal risk of responding, position as conventional first aid, friends and family as responders, support to call 911. CONCLUSION: To create an naloxone distribution program in emergency departments, family practice and substance use treatment services, stigma is a central design consideration for training and naloxone kits. Design choices that reference the iconography, type, and form of materials associated with first aid have the potential to satisfy the need to de-stigmatize overdose response.

Feasibility and Acceptability of an Overdose Prevention Intervention Delivered by Community Pharmacists for Patients Prescribed Opioids for Chronic Non-Cancer Pain.

There have been increases in prescriptions of high strength opioids for chronic non-cancer pain (CNCP), but CNCP patients perceive themselves as being at low risk of opioid overdose and generally have limited overdose awareness. This study examined how an overdose prevention intervention (opioid safety education, naloxone training, and take-home naloxone (THN)) delivered by community pharmacists for patients prescribed high-strength opioids for CNCP would work in practice in Scotland. Twelve patients received the intervention. CNCP patients and Community Pharmacists were interviewed about their experiences of the intervention and perceptions of its acceptability and feasibility. CNCP patients did not initially perceive themselves as being at risk of overdose but, through the intervention, developed insight into opioid-related risk and the value of naloxone. Pharmacists also identified patients' low risk perceptions and low overdose awareness. While pharmacists had positive attitudes towards the intervention, they outlined challenges in delivering it under time and resource pressures and during the COVID-19 pandemic. Overdose prevention interventions are required in the CNCP population as this group has elevated risk factors for overdose but are commonly overlooked. Customised overdose prevention interventions for CNCP patients attend to gaps in overdose awareness and risk perceptions in this population.

No Single Path: Review of Amy Sullivan's Opioid Reckoning

According to this framework, the pandemic is a two-part problem: one part virus, one part social resistance to the cure for the disease. [...]we hear that medical scientists have developed "gold standard" treatments for addiction, but that for reasons of bureaucratic lethargy, public skepticism, or sheer hopelessness among those suffering from addiction, the treatments are not adequately made available and sought out. The stories in the book are drawn from oral-history interviews that the author conducted with family members of people with addictions, doctors, community organizers, and treatment-center directors over a period of four years. Chapter Two reconstructs the life of a single man from the memories of his surviving family members, from the moment of his first exposure to opioids through fourteen separate rounds of addiction treatment and up to the moment of his fatal fentanyl overdose.

A survey of chloroquine use for prevention and treatment of COVID-19 in Nigeria

Background: Rampant chloroquine/hydroxychloroquine poisoning in Nigerian hospitals following suggestions of its possible efficacy in the treatment and prevention of the newly emerged COVID-19 disease informed this survey. Objective(s): The aim of this study was to assess the knowledge, attitude and perception of the Nigerian populace on the use of chloroquine in the COVID-19 pandemic. Method(s): This cross-sectional study was done by administering an electronic questionnaire created using Google Docs, through social media cascade methods including the WhatsApp application software to capture data on chloroquine use between April 20 and June 20, 2020. Result(s): Six hundred and twenty-eight people responded to the questionnaire (response rate 99.2%, mean age 41.05 +/- 12.3) from the six geopolitical zones in Nigeria with 556 (88.5%) having tertiary level education. Only 21 (3.3%) of the respondents took chloroquine for treatment or prevention. Respondents from the North-west geopolitical zones used chloroquine 5.8 (95% CI: 1.55, 21.52, p=0.02) more times than other zones while the age group 20-29 were 8.8 times more likely to use chloroquine than any other age group (95% CI: 3.53, 21.70, p = 0.00). Female respondents were 2.3 times more likely to use chloroquine than the males (OR 2.26 95% CI: 0.90-5.68;p=0.08) and those in the income bracket of N75,000-99,000, 2.5 times more than other income groups. Conclusion(s): Young adults, North-western geopolitical zone, and female gender should be target groups for education on rational chloroquine use. The danger of chloroquine overdose should be communicated to the general population in Nigeria.Copyright © 2023 Olukosi AY et al. Licensee African Health Sciences.

Optimizing Medication Treatment of Opioid Use Disorder During COVID-19 (SARS-CoV-2)

The COVID-19 health crisis joined, rather than supplanted, the opioid crisis as the most acutely pressing threats to US public health. In the setting of COVID-19, opioid use disorder treatment paradigms are being disrupted, including the fact that methadone clinics are scrambling to give "take-home"doses where they would typically not. The rapid transition away from in-person examination, dosing and group therapy in an era of social isolation calls for adjustments to clinical practice, including emphasizing patient-provider communication, favoring new inductees on buprenorphine and leveraging technology to optimize safety of medication treatment.

Expanding Access to Opioid Use Disorder Treatment Via Telehealth in Lewis County, Washington

Purpose of Study Lewis County is in southwest Washington state. With a population per square mile of 31.4, Lewis County is more rural than the rest of the state (101.2 per square mile). Citizens of the county, as well as health care workers at Chehalis Family Medicine (located in Lewis County), report concerns over rates of opioid use disorder. While Lewis County's age adjusted rate per 100,000 of deaths due to opioid overdose from 2014-2017 was lower than that of Washington state (7.6 vs 9.3), its rate of opioid related hospitalizations was significantly higher (110.7 vs 81.5). Methods Used An asset-based approach was used to learn how Lewis County has been addressing opioid use disorder amongst its citizens. Interviews with health care providers, patients at Chehalis Family Medicine, and the pastor of a local church were performed. These conversations revealed a lack of access to public transportation creates a major barrier to receiving opioid use disorder treatment. A literature review of interventions implemented in rural areas to deliver medically assisted opioid use disorder treatment was performed. Summary of Results The recent use of telemedicine to deliver suboxone treatment at Chehalis Family Medicine has increased access to medically assisted treatment of opioid use disorder. Telemedicine has become more prevalent with some loosening of governmental regulations due to the COVID-19 pandemic. Based upon articles by Guille et al and Weintraub et al, administration of medically assisted opioid use disorder treatment via telehealth offers a means to expand access to care in rural communities. They demonstrated no significant differences in patient outcomes. Implementation of telemedicine at other suboxone clinics in Lewis County would improve access to suboxone treatment. Conclusions A strength-based framework allows the existing assets in Lewis County to be appraised so future work can build upon what has already proved effective for the community. Regarding opioid use disorder treatment, Lewis county has several low barrier suboxone clinics which could increase access for rural patients through implementation of telemedicine. Chehalis Family Medicine's recent success with telemedicine in suboxone treatment could serve as a template for how to do so effectively.

High Pandemic-Related Mortality Amongst People with Hiv in Saskatchewan, Canada

Background: Saskatchewan, a Canadian Prairie province, faces a complicated HIV epidemic characterized by high rates of transmission due to injection drug use (IDU) and disproportionate representation of younger persons, women, and persons of Indigenous ethnicity. HIV incidence in Saskatchewan in 2021 was 19.7 per 100,000, 4.5 times higher than the Canadian average. Concurrently, during the COVID-19 pandemic, the recreational use of synthetic opioids such as fentanyl increased, leading to high numbers of overdose events & deaths. We characterized the difference in cascade of care outcomes & mortality amongst people with HIV (PWH) living in southern Saskatchewan during the COVID-19 pandemic. Method(s): We conducted a retrospective cohort study for all PWH cared for in the Infectious Diseases Clinic (IDC) at Regina General Hospital between December 31/19 and June 10/22. Age, sex, ethnicity & primary mode of HIV acquisition were collected from the IDC database, along with cascade of care & mortality data. Deaths, including most likely cause of death were characterized via individualized case review. Result(s): On December 31/19, IDC cared for 518 PWH. This increased to 585 by June 10/22. Amongst the current cohort, 245 (42%) were female, 163 (28%) were <= 35 years old, 306 (52%) were Indigenous, and 318 (54%) had acquired HIV through IDU. Cascade of care indicators worsened during the COVID-19 pandemic. 58.1% of the cohort were retained in care & 76.1% virally suppressed (HIV RNA <= 200 copies/mL) in December 2019, decreasing to 51.3% retained (p=0.02) & 68.8% suppressed (p=0.06) by June 2022. There were 80 deaths during the study period, representing 15.4% of the cohort from the end of 2019. Most deaths (49, 61.3%) were due to suspected or confirmed drug overdose. 10 (12.5%) additional deaths occurred due to complications from IDU (i.e., sepsis). No deaths were directly attributable to COVID-19. Most who died acquired HIV from IDU (69/80, 86%). Conclusion(s): We describe intersecting epidemics of HIV and IDU disproportionately affecting high-risk populations, leading to significant morbidity & mortality during the COVID-19 pandemic. Contributing factors may have included disruption of safe opioid supply and disrupted access to harm reduction services due to COVID-19. Comprehensive population-level harm reduction and addictions management strategies are urgently needed to reduce morbidity & mortality from drug use amongst PWH in Saskatchewan.

It's Not Always Just a Rash

[...]it may have been difficult to get him admitted since it is not our current practice to admit patients with mild COVID-19 infections. [...]our financial incentives are to see many patients each shift, which does not always leave time to care for more socially challenging cases. Burnout is rising in the field of emergency medicine, and I think a part of that burnout can be attributed to the uphill battle that providers are fighting daily to care for patients that our health system leaves behind.

Racial and ethnic differences and COVID-19 pandemic-related changes in drug overdose deaths in North Carolina.

PURPOSE: To examine racial and ethnic differences and COVID-19 pandemic-related changes in key characteristics of drug overdose deaths in North Carolina. METHODS: We used North Carolina State Unintentional Drug Overdose Reporting System data to describe specific drug-involvement, bystander presence, and naloxone administration for drug overdose deaths by race and ethnicity during pre-COVID-19 (May 2019-February 2020) and COVID-19 periods (March 2020-December 2020). RESULTS: For all racial and ethnic groups, drug overdose death rates and the percentage with fentanyl and alcohol involvement increased from the pre-COVID-19 to COVID-19 period, with fentanyl involvement highest among American Indian and Alaska Native (82.2%) and Hispanic (81.4%) individuals and alcohol involvement highest among Hispanic individuals (41.2%) during the COVID-19 period. Cocaine involvement remained high among Black non-Hispanic individuals (60.2%) and increased among American Indian and Alaska Native individuals (50.6%). There was an increase in the percentage of deaths with a bystander present from the pre-COVID-19 to COVID-19 period for all racial and ethnic groups, with more than half having a bystander present during the COVID-19 period. There was a decrease in the percentage of naloxone administered for most racial and ethnic groups, with the lowest percentage among Black non-Hispanic individuals (22.7%). CONCLUSIONS: Efforts to address increasing inequities in drug overdose deaths, including expanded community naloxone access, are needed.

Acceptability of a Fentanyl Vaccine to Prevent Opioid Overdose and Need for Personalized Decision-Making.

BACKGROUND: The opioid epidemic worsened during the coronavirus disease 2019 (COVID-19) pandemic. Synthetic opioids (primarily fentanyl) comprise the most common drugs involved in overdose (OD) death. A vaccine that blocks fentanyl from reaching the brain to prevent OD is under development, and insight is needed into its acceptability. METHODS: Using a semi-structured interview guide, persons with opioid use disorder (OUD), family, professionals, and the public were interviewed about attitudes and concerns regarding a fentanyl vaccine. Reactions to fictional clinical vignettes of persons at risk of OUD because of pain and/or substance use histories were collected, analyzed, and quantified for favorability. Interviews were transcribed, coded, and analyzed thematically. RESULTS: Among N = 64 participants, (70.3% female, average age 32.4 years), attitudes were favorable toward a fentanyl vaccine, with preference for lifelong durability (76% of n = 55 asked). Perceived benefits centered on the potential for a life-saving intervention, suffering averted, healthcare dollars saved, and the utility of a passive harm reduction strategy. Concerns centered on uncertainty regarding vaccine safety, questions about efficacy, worry about implications for future pain management, stigma, and need for supportive counseling and guidance to personalize decision making. Reactions to vignettes revealed complex attitudes toward fentanyl vaccination when considering recipient age, health history, and future risks for addiction and pain. CONCLUSIONS: Positive responses to a fentanyl vaccine were found along with appreciation for the complexity of a vaccine strategy to prevent OD in the setting of pain and uncertain durability. Further research is needed to elucidate operational, ethical, and communications strategies to advance the model.

The increase in benzodiazepine-laced drugs and related risks in Canada: The urgent need for effective and sustainable solutions.

The overdose crisis in Canada has continuously evolved and is increasingly challenging to contain, while efforts from governments and policymakers to address it have often fallen short and resulted in unintended consequences. One of the main repercussions has been an unprecedented rise in adulterants in the illegal drug supply, including a wide array of pharmacological and psychoactive compounds and chemicals, which has resulted in a progressively toxic drug supply. Most recently, there has been a stark increase in synthetic benzodiazepine-laced opioids (i.e., 'benzodope') in some Canadian jurisdictions. This unique combination carries distinct and amplified risks for people who use drugs including fatal and non-fatal overdoses, increased dependence and withdrawal symptoms, and places them in extremely vulnerable positions. The emergence of benzodiazepines within the illicit drug supply has substantially contributed to drug-related morbidity and mortality in Canada, and has further complicated current public health initiatives and overdose prevention efforts. This reality underscores the need for effective and sustainable policy solutions to address the evolving overdose epidemic including increased knowledge and education on the specific harms of opioid and benzodiazepine co-use (especially in regards to the complexity of opioid/benzodiazepine overdoses), scaling-up harm reduction measures, and eliminating the toxic drug supply altogether.
