Tianeptine as an opiate replacement in a patient on methadone treatment: A case report.

Tianeptine, an antidepressant and full µ-opioid receptor agonist, has increased in popularity and has been used as an over-the-counter supplement over the past decade. Due to its well-documented euphoric effects, there exists elevated risk for potential abuse. Buprenorphine-naloxone has been successfully utilized to treat opioid use disorder (OUD) in patients concurrently using tianeptine, limiting withdrawal symptoms and abstinence. However, there is limited evidence on the management of tianeptine use disorder, specifically methadone or naltrexone. The current opioid epidemic, the emerging use of tianeptine, and the lack of physician awareness have emphasized the need for further research on the role of tianeptine in medication-assisted treatment for OUD. This case report aims to demonstrate how medication-assisted therapy can be successfully utilized in a patient with opioid and severe other (tianeptine) drug use disorder.

Revisiting Estrogen for the Treatment of Endocrine-Resistant Breast Cancer: Novel Therapeutic Approaches.

Estrogen receptor (ER)-positive breast cancer is the most common subtype, representing 70-75% of all breast cancers. Several ER-targeted drugs commonly used include the selective estrogen receptor modulator (SERM), tamoxifen (TAM), aromatase inhibitors (AIs) and selective estrogen receptor degraders (SERDs). Through different mechanisms of action, all three drug classes reduce estrogen receptor signaling. Inevitably, resistance occurs, resulting in disease progression. The counterintuitive action of estrogen to inhibit ER-positive breast cancer was first observed over 80 years ago. High-dose estrogen and diethylstilbestrol (DES) were used to treat metastatic breast cancer accompanied by harsh side effects until the approval of TAM in the 1970s. After the development of TAM, randomized trials comparing TAM to estrogen found similar or slightly inferior efficacy but much better tolerability. After decades of research, it was learned that estrogen induces tumor regression only after a period of long-term estrogen deprivation, and the mechanisms of tumor regression were described. Despite the long history of breast cancer treatment with estrogen, this therapeutic modality is now revitalized due to the development of novel estrogenic compounds with improved side effect profiles, newly discovered predictive biomarkers, the development of non-estrogen small molecules and new combination therapeutic approaches.

Hospital Readmission in Alcohol Use Disorder Patients: The Role of Anti-Craving Medications and Discharge Disposition.

Background: Alcohol use disorder (AUD) results in frequent hospital readmissions. Although the literature has shown the efficacy of anti-craving medications (ACM), they are infrequently prescribed upon discharge. The outcomes of discharge to substance use treatment facilities (STF) have also not been fully explored. This study seeks to determine the impact of ACM as well as discharge to STF on readmissions for people with AUD. Methods: This retrospective case-control study analyzed encounters made within HCA Healthcare hospitals across the United States from 2016 to 2018 for adults with AUD. The case definition was the presence of ACM defined as acamprosate or naltrexone upon discharge as well as discharge disposition (STF vs. all others). The main outcomes were the likelihood of 30- and 90-day readmission and blood alcohol concentration (BAC) on 30-day readmission in cases versus adults with AUD declining/not referred to an STF or not using ACM. The controlled variables included age, sex, race, and insurance status. Results: A total of 14 691 patients were identified for the study. Of these, 3308 patients were prescribed ACM and 1125 patients were discharged to an STF. Patients without ACM were 1.18 times more likely to be readmitted within 30 days (95% CI, 1.07-1.30; P = .0005). Patients discharged to an STF were 1.57 times more likely to be readmitted within 30 days (95% CI, 1.37-1.79; P < .0001), but these patients had a BAC that was 26.74 units lower on 30-day readmission than those who were not discharged to an STF. Conclusion: The prescription of ACM on discharge was associated with decreased 30-day readmission rates. The lower BAC of those who were readmitted within 30 days suggests discharge to STF may be beneficial for the treatment of AUD in the longer term. Practitioners are encouraged to prescribe ACM for people admitted with AUD to reduce the likelihood of 30-day readmission.
