Patients' perspectives on buprenorphine subcutaneous implant: a case series.

BACKGROUND: Considering the enormous burden represented by the opioid use disorder (OUD), it is important to always consider, when implementing opioid agonist therapy (OAT), the potential impact on patient's adherence, quality of life, and detoxification. Thus, the purpose of the study is to evaluate how the introduction of a novel OAT approach influences these key factors in the management of OUD. CASE PRESENTATION: This article marks the pioneering use of OAT through buprenorphine implant in Europe and delves into the experience of six patients diagnosed with OUD at a relatively young age. The patients, comprising both males and a female, are of Caucasian Italian and African Italian ancestry (case 4) and exhibit an age range from 23 to 63, with an average drug abuse history of 19 ± 12 years. All patients were on stable traditional OAT before transitioning to buprenorphine implants. Despite the heterogeneity in social and educational backgrounds, health status, and drug abuse initiation histories, the case series reveals consistent positive treatment outcomes such as detoxification, absence of withdrawal symptoms and of side effects. Notably, all patients reported experiencing a newfound sense of freedom and improved quality of life. CONCLUSIONS: These results emphasise the promising impact of OAT via buprenorphine implants in enhancing the well-being and quality of life in the context of OUD.

The experience of buprenorphine implant in patients with opioid use disorder: a series of narrative interviews.

Background: This study used narrative medicine (NM) to assess the point of view of patients with opioid use disorder (OUD) and the impact that addiction and a new treatment approach via buprenorphine implant had on their daily lives as compared with previous oral Opioid Agonist Therapy (OAT). Methods: Five patients with OUD undergoing treatment with a buprenorphine subcutaneous implant participated voluntarily and provided their anonymity by self-describing, in response to questions prompted by the clinician, their experience with this innovative therapy. The narratives were analyzed according to standard NM methodology. Citations of patients' positive or negative experiences with traditional OAT and buprenorphine implant were classified according to five categories-patient's determination toward complete opioid abstinence, emotional impact, impact on life, smoothness of therapy, and therapy dependency-and quantified to obtain a picture of the overall therapy experience. Results: The analysis revealed the extent of the burden not only of addiction but also of the traditional OAT on patients' life, including relationships with family, job management, and free time. Conversely, the therapy with buprenorphine implant revealed a significant improvement in the quality of life of the patients, who also largely reported a positive emotional outcome during this therapy, as well as a solid determination to achieve complete recovery. Conclusions: This study illustrates the complex problems of living with OUD and provides insights into the added value of an innovative buprenorphine implant therapy that, due to its administration route and prolonged duration, allows patients to take an additional step toward total opioid abstinence and complete recovery of daily life.

Cerebrospinal fluid interferon-gamma-inducible protein 10 (IP-10, CXCL10) in HIV-1 infection.

Interferon-gamma-inducible protein (IP-10 or CXCL10) is a potent chemoattractant and has been suggested to enhance retrovirus infection and mediate neuronal injury. In order to assess this chemokine in central nervous system (CNS) HIV infection, we measured the cerebrospinal fluid (CSF) and plasma concentrations of CXCL10 by immunoassay in samples derived from 97 HIV-infected subjects across a spectrum of immunological progression and CNS complications and from 16 HIV seronegative control subjects studied at three clinical centers between 1994 and 2001. We also examined changes in the CSF and plasma CXCL10 concentrations in 30 subjects starting and three stopping antiretroviral therapy. CSF CXCL10 concentrations: (1) correlated with CSF HIV RNA and white blood cell (WBC) counts, but not with blood CXCL10, HIV RNA, or CD4 counts; (2) were increased in subjects with primary and asymptomatic HIV infections and AIDS dementia complex, but less frequently in those with more advanced infection, with or without CNS opportunistic diseases except cytomegalovirus encephalitis; (3) decreased in subjects starting antiretroviral in association with decreases in CSF and plasma HIV RNA and CSF WBCs; and (4) conversely, increased in subjects stopping treatment in parallel with CSF HIV RNA and WBCs. These results confirm that CSF CXCL10 associates closely with both CSF HIV and WBCs and suggest that this chemokine may be both a response to and contributing determinant of local infection. High CSF levels may be useful in the diagnosis of ADC in subjects with advanced immunosuppression in whom CMV encephalitis has been ruled out, though this issue requires further study.
