RESUMO

INTRODUCTION: Buprenorphine is used to treat opioid use disorder (OUD). However, therapy is often disrupted during acute pain episodes, and re-initiation is often deferred due to intolerable interruption in opioid analgesics. This case report describes a unique strategy for inducing buprenorphine without stopping opioid analgesics. CASE: One patient with OUD and acute pain was initiated on buprenorphine using intravenous microdosing without precipitated withdrawal or pain exacerbation. Full agonist opioids were successfully weaned after discharge and the patient was linked with a community-based treatment program. CONCLUSION: This case describes use of intravenous buprenorphine to treat OUD and acute pain without adverse consequences.

RESUMO

BACKGROUND: Buprenorphine is a life-saving treatment for opioid use disorder (OUD). Low-dose initiation (LDI) is an emerging buprenorphine initiation strategy that circumvents barriers associated with standard initiation. This study aims to describe tolerability and completion of LDI using intravenous (IV) buprenorphine and to define dosing protocols in a cohort of patients hospitalized in an urban academic hospital. METHODS: Data was collected via retrospective chart review for IV buprenorphine LDI cases initiated between September 1, 2020 and February 28, 2021. Cases were excluded if diagnostic criteria for OUD was not met, Clinical Opiate Withdrawal Scale (COWS) scores were not recorded, or sublingual (SL) buprenorphine was given within 24 h before IV buprenorphine. Completion of LDI and COWS data were assessed for all cases. Cases were categorized based on adherence to a dosing strategy and LDI indication, including OUD and acute pain, non-prescribed fentanyl exposure, and transition from methadone. RESULTS: Seventy-two cases were identified, and thirteen cases were excluded, leaving 59 cases in the population. Of these cases, 72.9% (43/59) tolerated LDI, and 91.5% (54/59) completed buprenorphine initiation. Forty-four (44/59, 75%) cases were adherent. Median duration of LDI within the adherent group was 23.7 h (IQR 22.8-27.0), 37.1 h (IQR 36.2-40.9), and 48.8 h (IQR 47.0-52.4) for the "rapid," "moderate," and "slow" dosing strategies, respectively. CONCLUSIONS: IV buprenorphine LDI was tolerated and completed in a majority of patients. Dosing protocols allowed for rapid transition to sublingual buprenorphine. Acute pain or recent methadone or fentanyl exposure may inform IV LDI dosing strategy selection.

RESUMO

For patients with opioid use disorder transitioning from methadone or requiring opioid analgesia, initiating buprenorphine for opioid use disorder can be difficult because of the risk of precipitated withdrawal. Low-dose initiation, also known as micro-dosing, is an alternative to standard initiation. Prior studies relied on nonstandard dosing of tablets or films, patches, or buccal formulations, all of which are unavailable in many hospitals. We report a novel approach to micro-dosing using intravenous buprenorphine. Two patients, one on methadone maintenance and another requiring postoperative opioid analgesia, were transitioned to buprenorphine with concurrent full-agonist opioids and without precipitated withdrawal.

RESUMO

OBJECTIVES: Clinical practice guidelines for eradication of Pseudomonas aeruginosa (PA) in patients with cystic fibrosis (CF) have been established, but current studies have not assessed how these guidelines translate into clinical practice. This study aimed to characterize the real-world eradication strategies, eradication rates, and microbiologic outcomes of patients with first acquisition of PA at an urban pediatric CF center. METHODS: The Cystic Fibrosis Foundation Patient Registry was used to identify patients with CF who received care between January 2014 and September 2018 and had PA isolated from an airway culture. Patients were included if they had a first positive PA culture or the first positive culture in 2 years. Data regarding patient demographics, timing and results of airway cultures, and treatment regimens were collected. RESULTS: Over a 3.75-year period, 75 patients had an initial positive culture for PA. Of those patients, 74 (98.7%) received eradication treatment. Tobramycin inhalation solution (TIS) monotherapy was the most common regimen prescribed (52.7%) followed by TIS plus an oral fluoroquinolone (28.4%) (TIS + FQ). Of those treated, 62 (83.8%) patients had eradication of PA at first follow-up culture (median, 58 days; IQR, 49-77 days). Eradication rates (84.6% vs 76.2%, p = 0.421) and times to recurrence (6.37 months vs 5.1 months, p = 0.726) were comparable between TIS and TIS + FQ cohorts. CONCLUSIONS: The eradication rate for PA in clinical practice is similar to that published in the literature. Consistent with published guidelines, these microbiologic outcomes do not support the addition of an oral FQ to TIS for initial PA eradication.

RESUMO

Anti-factor Xa (anti-Xa) monitoring of unfractionated heparin (UFH) is associated with less time to achieve therapeutic anticoagulation compared to the activated partial thromboplastin time (aPTT). However, it is unknown whether clinical outcomes differ between these methods of monitoring. The aim of this research was to compare the rate of venous thrombosis and bleeding events in patients that received UFH monitored by anti-Xa compared to the aPTT. A retrospective review of electronic health records identified adult patients that received UFH given intravenously (IV) for ≥2 days, with either anti-Xa or aPTT monitoring at an academic tertiary care hospital. This was a pre/post study design conducted between January 1 to December 30, 2014 (aPTT), and January 1 to December 30, 2016 (anti-Xa). All UFH adjustments were based on institutional nomograms. The primary outcome was venous thrombosis and the secondary outcome was bleeding, both of which occurred between UFH administration and discharge from the index hospitalization. A total of 2500 patients were in the anti-Xa group and 2847 patients aPTT group. Venous thrombosis occurred in 10.2% vs 10.8% of patients in the anti-Xa and aPTT groups, respectively (P = .49). Bleeding occurred in 33.7% vs 33.6% of patients in the anti-Xa and aPTT groups, respectively (P = .94). Anti-Xa monitoring was not an independent predictor of either outcome in multivariate logistic regression analyses. Our study found no difference in clinical outcomes between anti-Xa and aPTT-based monitoring of UFH IV.

RESUMO

BACKGROUND: Bronchial stenosis is a known complication of lung transplantation, but there are limited data regarding whether transplant recipients with bronchial stenosis develop more infectious complications than those without bronchial stenosis. METHODS: We conducted a retrospective single-center observational cohort study between January 1, 2011 and September 29, 2016 of 35 lung transplant recipients diagnosed with bronchial stenosis and a random sample of 35 lung transplant recipients without bronchial stenosis. Data collected included donor/recipient demographic and anatomic information, respiratory cultures, episodes of respiratory infections diagnosed using CDC-NNIS criteria, hospitalizations, and 1-year all-cause mortality. Patients were followed up to 1 year after transplant. RESULTS: Bronchial stenosis occurred at a median of 54 days post-transplant (range 5-365 days). Bronchial stenosis patients spent more time in the hospital (87.4 vs 46.8 days, P = 0.011) and had more total hospitalizations (4.54 vs 2.37, P < 0.01) than their counterparts. The relative risk of pneumonia among cases vs controls was 4.0 (95% CI 2.2-7.3, P < 0.01); for purulent tracheobronchitis the relative risk was 3.1 (95% CI 1.6-6.1, P < 0.01). Patients with bronchial stenosis were significantly more likely to have respiratory cultures growing Staphylococcus aureus (RR 5.0; P = 0.001) and Pseudomonas aeruginosa (RR 2.1, P = 0.026). Mortality within the first year following transplant was equal in both the groups (14.3% vs 14.3%). CONCLUSIONS: There was no significant increase in 1-year mortality for lung transplant patients who developed bronchial stenosis. However, bronchial stenosis patients had significantly higher risks of pneumonia and tracheobronchitis, and spent more days in the hospital than those without bronchial stenosis.
