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.

Real World Experience of Eradication at an Urban Pediatric Cystic Fibrosis Center.

J Pediatr Pharmacol Ther 2020 ;25(7):623-628

Objectives: Clinical practice guidelines for eradication of (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.

Clinical outcomes with unfractionated heparin monitored by anti-factor Xa vs. activated partial Thromboplastin time.

Am J Hematol 2019 09 16;94(9):1015-1019. Epub 2019 Jul 16.

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.

Infectious complications of bronchial stenosis in lung transplant recipients.

Transpl Infect Dis 2019 Aug 18;21(4):e13100. Epub 2019 May 18.

Section of Infectious Diseases, Department of Internal Medicine, Temple University Hospital, Philadelphia, Pennsylvania.

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.
