Abstract
It has been established that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses angiotensin-converting enzyme 2 (ACE2), a membrane-bound regulatory peptide, for host cell entry. Renin-angiotensin-aldosterone system (RAAS) inhibitors have been reported to increase ACE2 in type 2 pneumocyte pulmonary tissue. Controversy exists for the continuation of ACE inhibitors, angiotensin II receptor blockers, and mineralocorticoid receptor antagonists in the current pandemic. ACE2 serves as a regulatory enzyme in maintaining homeostasis between proinflammatory angiotensin II and anti-inflammatory angiotensin 1,7 peptides. Derangements in these peptides are associated with cardiovascular disease and are implicated in the progression of acute respiratory distress syndrome. Augmentation of the ACE2/Ang 1,7 axis represents a critical target in the supportive management of coronavirus disease 2019–associated lung disease. Observational data describing the use of RAAS inhibitors in the setting of SARS-CoV-2 have not borne signals of harm to date. However, equipoise persists, requiring an analysis of novel agents including recombinant human-ACE2 and existing RAAS inhibitors while balancing ongoing controversies associated with increased coronavirus infectivity and virulence.

Abstract
BACKGROUND Chronic lung allograft dysfunction (CLAD) is the major complication limiting long-term survival in lung transplant recipients (LTRs), with those developing donor-specific anti-human leukocyte antigen (HLA) antibodies (DSAs) previously found to have increased risk for CLAD. However, as DSA responses vary in timing of development, specificity, breadth, persistence, and complement-binding capacity, we hypothesized that these characteristics would impact CLAD and survival outcomes. METHODS We retrospectively analyzed DSA characteristics and outcomes in a single-center cohort of 582 LTRs who had serum samples collected prospectively from 2010 to 2016. Luminex-based single antigen bead assays were performed to assess DSA. RESULTS DSAs were detected in 247 LTRs (42%), of which 124 (21.3%) were de novo DSAs and 53 (9.1%) were complement-binding (C1q+). CLAD developed in 208 LTRs (35.7%) during the follow-up period, with 67.8% determined as bronchiolitis obliterans syndrome phenotype and 32.2% as restrictive allograft syndrome phenotype. We found a shorter time to CLAD in LTRs with persistent DSAs (p = 0.04) and HLA-DQ-specific DSAs (p = 0.03). LTRs who developed C1q+ DSAs had significantly shorter time to CLAD (p < 0.001), with 100% of C1q+ DSAs being persistent and no differences between CLAD phenotypes. CLAD-free survival was significantly reduced in LTRs who developed C1q+ DSAs (p = 0.001), HLA-DQ-specific DSAs (p = 0.03), and multiple DSAs (p = 0.02). CONCLUSIONS Together, our findings demonstrate that DSA characteristics of persistence, HLA-DQ specificity, and C1q+ DSAs are associated with shorter time to CLAD. Additionally, C1q+, HLA-DQ-specific, and multiple DSAs are associated with decreased CLAD-free survival. These characteristics may improve DSA risk stratification for deleterious outcomes in LTRs.

Abstract
BACKGROUND A lung transplant patient with invasive aspergillosis (IA) manifested symptoms of voriconazole-induced transaminitis with systemic voriconazole and progression of IA after switching to oral posaconazole. With limited options for standard triazole therapy, aerosolized delivery with one of the second-generation triazoles was considered. METHODS Feasibility for aerosolized delivery was evaluated using cascade impactor and analysis of physicochemical characteristics of voriconazole (10 mg/mL) and posaconazole (6, 12 mg/mL) solutions. RESULTS Both triazoles showed favorable characteristics for aerosol delivery with mass median aerodynamic diameter, geometric standard deviation, respirable fraction (<5.4 µm) of 2.8 µm, 2.0, 86%; 3.4 µm, 2.4, 78%; and 3.0 µm, 2.3, 79% for voriconazole and 6, 12 mg/mL of posaconazole, respectively. Aspergillus fumigatus isolate from the patient was more susceptible to voriconazole, and hence aerosolized voriconazole was introduced around the third month posttransplant at 40 mg TID for 1 week, 40 mg BID for 1 week, followed by 40 mg daily thereafter, along with IV caspofungin (50 mg/d) and liposomal amphotericin B (300 mg/d). The aerosol regimen was well tolerated by the patient with undetectable trough plasma levels of voriconazole. Bronchoscopy at the fourth month revealed improvement in anastomotic plaques with reduction in bronchoalveolar lavage galactomannan values (7.48-2.15 ng/mL). This consolidated aerosolized and intravenous regimen was maintained until 2.97 years posttransplant. CONCLUSIONS The intravenous solutions of both second-generation triazoles showed characteristics that were suitable for aerosol delivery. Our report further adds to the therapeutic experience with the use of aerosolized voriconazole for IA in a lung transplant patient.

Abstract
The purpose of this study was to examine the influence of extracorporeal membrane oxygenation (ECMO) as a bridge to reoperative lung transplantation (LT) on outcomes and survival. A total of 1960 LT recipients transplanted a second time between 2005 and 2017 were analyzed using the United Network for Organ Sharing (UNOS) Organ Procurement and Transplantation Network (OPTN). Of these recipients, 99 needed ECMO as a bridge to reoperative LT. Mean age was 50 ± 14 years, 47% were females, and the group with ECMO was younger [42 (30-59) vs. 55 (40-62) years]. In both univariate and multivariable analyses (adjusting for age and gender), the ECMO group had greater incidence of prolonged ventilation >48 h (83% vs. 40%, P < 0.001) and in-hospital dialysis (27% vs. 7%, P < 0.001). There were no differences in incidence of acute rejection (15% vs. 11%, P = 0.205), airway dehiscence (4% vs. 2%, P = 0.083), stroke (3% vs. 2%, P = 0.731), or reintubation (20% vs. 20%, P = 0.998). Kaplan-Meier survival analysis showed the ECMO group had reduced 1-year survival (66.6% vs. 83.0%, P < 0.001). After covariate adjustment, the ECMO group only had increased risk for 1-year mortality in the 2005-2011 era (HR = 2.57, 95% CI = 1.45-4.57, P = 0.001). For patients who require reoperative LT, bridging with ECMO was historically a significant predictor of poor outcome, but may be improving in recent years.

Abstract
Epstein-Barr virus (EBV)-associated posttransplant lymphoproliferative disorder (EBV-PTLD) is a serious complication in lung transplant recipients (LTRs) associated with significant mortality. We performed a single-center retrospective study to evaluate the risks for PTLD in LTRs over a 7-year period. Of 611 evaluable LTRs, we identified 28 cases of PTLD, with an incidence of 4.6%. Kaplan-Meier analysis showed a decreased freedom from PTLD in idiopathic pulmonary fibrosis (IPF)-LTRs (P < .02). Using a multivariable Cox proportional hazards model, we found IPF (hazard ratio [HR] 3.51, 95% confidence interval [CI] 1.33-8.21, P = .01) and alemtuzumab induction therapy (HR 2.73, 95% CI 1.10-6.74, P = .03) as risk factors for PTLD, compared to EBV mismatch (HR: 34.43, 95% CI 15.57-76.09, P < .0001). Early PTLD (first year) was associated with alemtuzumab use (P = .04), whereas IPF was a predictor for late PTLD (after first year) (P = .002), after controlling for age and sex. Kaplan-Meier analysis revealed a shorter time to death from PTLD in IPF LTRs compared to other patients (P = .04). The use of alemtuzumab in EBV mismatch was found to particularly increase PTLD risk. Together, our findings identify IPF LTRs as a susceptible population for PTLD. Further studies are required to understand the mechanisms driving PTLD in IPF LTRs and develop strategies to mitigate risk.

Abstract
Objective. To design, integrate the curriculum for, and evaluate an innovative program to facilitate placement of students into postgraduate pharmacy residency training programs involving direct patient care. Methods. The Pharmacotherapy Scholars Program (PSP) was designed to prepare fourth-professional year students to become highly proficient in a direct patient care role and to successfully match with postgraduate residency training programs. The following elements were included in the year-long curriculum: integrated synchronous advanced pharmacy practice experiences with personal advising, team-based mentoring, peer-to-peer learning, longitudinal research, and professional development. Program goals were modeled after the accreditation standards for postgraduate year one (PGY1) pharmacy residency programs. Program faculty members ensured that the PSP had a broad scope, included rigorous student assessments, had a strong research focus, and provided scholarship opportunities. Results. Sixty-eight students completed the program from fall 2013 through spring 2019. The overall residency match rate was 93%. Students' performance on both knowledge and clinical skills assessments significantly improved after completing the program. There was an approximately 15% increase in knowledge and a 30% improvement in clinical skills based on comprehensive readiness assessments and an intermittent clinical examination that used patient simulation, respectively. Conclusion. The Pharmacotherapy Scholars Program is an innovative training program designed to enhance PharmD students' preparation for advanced clinical training. Students who completed the PSP achieved a high PGY1 residency placement rate while demonstrating significant improvements in pharmacotherapy knowledge and clinical skills in direct patient care activities.

Abstract
RATIONALE Cytomegalovirus (CMV)-related morbidities remain one of the most common complications after lung transplantation and have been linked to allograft dysfunction, but the factors that predict high risk for CMV complications and effective immunity are incompletely understood. OBJECTIVES To determine if short telomeres in idiopathic pulmonary fibrosis (IPF) lung transplant recipients (LTRs) predict the risk for CMV-specific T-cell immunity and viral control. METHODS We studied IPF-LTRs (n = 42) and age-matched non-IPF-LTRs (n = 42) and assessed CMV outcomes. We measured lymphocyte telomere length and DNA sequencing, and assessed CMV-specific T-cell immunity in LTRs at high risk for CMV events, using flow cytometry and fluorescence in situ hybridization. MEASUREMENTS AND MAIN RESULTS We identified a high prevalence of relapsing CMV viremia in IPF-LTRs compared with non-IPF-LTRs (69% vs. 31%; odds ratio, 4.98; 95% confidence interval, 1.95-12.50; P < 0.001). Within this subset, IPF-LTRs who had short telomeres had the highest risk of CMV complications (P < 0.01) including relapsing-viremia episodes, end-organ disease, and CMV resistance to therapy, as well as shorter time to viremia versus age-matched non-IPF control subjects (P < 0.001). The short telomere defect in IPF-LTRs was associated with significantly impaired CMV-specific proliferative responses, T-cell effector functions, and induction of the major type-1 transcription factor T-bet (T-box 21;TBX21). CONCLUSIONS Because the short telomere defect has been linked to the pathogenesis of IPF in some cases, our data indicate that impaired CMV immunity may be a systemic manifestation of telomere-mediated disease in these patients. Identifying this high-risk subset of LTRs has implications for risk assessment, management, and potential strategies for averting post-transplant CMV morbidities.

Abstract
Occupational lung diseases (OLD) including silicosis, asbestosis, and pneumoconiosis progress to end stage lung disease requiring lung transplantation (LT). Prognosis and treatment of OLDs are poorly understood and a paucity of data exists regarding LT outcomes. Additionally, transplant operative complexity for patients with OLD is high. A single center retrospective review of all single and bilateral LT recipients between May 2005 and Oct 2016 was performed. Patients were grouped by OLD, and nearest neighbor matching was performed at a ratio of 1:3 cases to controls. Thirty cases were matched to 88 controls. Seventeen patients (57%) with OLD required intraoperative support with either extra-corporeal membrane oxygenation (ECMO) or cardiopulmonary bypass (P = 0.02), and 5 (17%) required delayed chest closure (P = 0.05) which was more frequent than matched controls. In addition, operative time was significantly longer in patients with OLD (P = 0.03). Despite these factors, there were no significant differences in immediate post-operative outcomes including mechanical ventilator support, post-operative ECMO, and tracheostomy. Chronic lung allograft dysfunction and long-term survival were also similar between cases and controls. OLDs should not preclude LT. The operation should be performed at experienced centers.

Abstract
INTRODUCTION The number of solid organ transplants completed annually continues to trend upwards each year. Despite this, maintenance immunosuppression available on the market has remained relatively stagnant. Standard triple immunosuppression, composed typically of tacrolimus, mycophenolate, and steroids, lead to many side effects that limit the use of these medications. Tacrolimus, specifically, causes nephrotoxicity that can lead to renal dysfunction requiring a kidney transplant down the road. Alternative therapies for the management of immunosuppression need to be identified to try to mitigate these adverse effects. BODY: Cytokines are responsible for facilitating T cell differentiation and lead to the activation of inflammatory mediators that can contribute to graft damage and ultimately rejection. IL-4, IL-6, IL-12/23, and IL-15 are attractive targets for medications to try to ameliorate graft rejection. Various cytokine-targeted medications are currently available on the market for the treatment of inflammatory and autoimmune conditions such as rheumatoid arthritis, psoriatic arthritis, Crohn's, and multiple sclerosis. CONCLUSION This article reviews cytokine involvement in alloimmunity and the potential role cytokine-targeted therapy may play in prevention of allograft rejection in solid organ transplant recipients.

Abstract
BACKGROUND: Hypogammaglobulinemia (HGG), immunoglobulin G (IgG) <700 mg/dL, is associated with infections, chronic lung allograft dysfunction, and death following lung transplantation. This study evaluates the use of on-demand intravenous IgG in lung transplant recipients with HGG. MATERIALS AND METHODS: This single-center retrospective cohort study of adult lung recipients evaluated 3 groups, no, untreated (u), or treated (t) HGG at first IgG administration or a matched time posttransplant. Primary outcome was freedom from allograft dysfunction. Secondary outcomes included development of advanced dysfunction, rejection, infection burden, and mortality. RESULTS: Recipients included 484 (no HGG: 76, uHGG: 192, tHGG: 216). Freedom from chronic allograph dysfunction was highest in the non-HGG group 2 years post-enrollment (no HGG 77.9% vs uHGG 56.4% vs tHGG 52.5%; P = .002). Freedom from advanced dysfunction was significantly different 2 years post-enrollment (no HGG 90.5% vs uHGG 84.7% vs tHGG 75.4%; P = .017). Patients without HGG and those with uHGG had less mortality at 2 years post-enrollment (no HGG 84.2% vs uHGG 81.3% vs tHGG 64.8%; P < .001). Gram-negative pneumonias occurred more often in the tHGG group ( P = .02). CONCLUSIONS: Development of chronic lung allograft dysfunction, patient survival, rejection burden, and key infectious outcomes in lung transplant recipients were still problematic in the context of on-demand IgG therapy. Prospective studies are warranted.

Abstract
Current immunosuppressive regimens with calcineurin inhibitors have improved the management of patients after transplantation. However, their adverse effects are linked to increased morbidity and limit the long-term survival of heart and lung transplant recipients. Belatacept, a costimulation inhibitor interfering with the interaction between CD28 on T cells and the B7 ligands on antigen presenting cells, has shown success and is currently approved for use in renal transplant recipients. Furthermore, it lacks many of the cardiovascular, metabolic, neurologic, and renal adverse of effects of calcineurin inhibitors that have the largest impact on long-term survival in cardiothoracic transplant. Additionally, it requires no therapeutic drug monitoring and is only administered once a month. Limitations to belatacept use have been observed that must be considered when comparing immunosuppression options. Despite this, maintenance immunosuppression with belatacept has the potential to improve outcomes in cardiothoracic transplant recipients, as it has with kidney transplant recipients. However, no large clinical trials investigating belatacept for maintenance immunosuppression in heart and lung transplant recipients exist. There is a large need for focused research of belatacept in cardiothoracic transplantation. Belatacept is a viable treatment option for maintenance immunosuppression, and it is reasonable to pursue more evidence in cardiothoracic transplant recipients.

Abstract
CONTEXT Anticoagulation therapy is common in thoracic transplant recipients. Direct oral anticoagulants (DOACs) are alternatives to warfarin therapy, but characterization of their use in solid organ transplant is absent. OBJECTIVE The primary objective of this study was to describe a thoracic transplant patient population initiated on DOAC therapy. Secondary objectives were to assess adverse reactions, venous thromboembolism (VTE) recurrence, and drug-drug interactions during DOAC therapy. STUDY DESIGN Single-center retrospective cohort study. SETTING A tertiary care medical center including inpatient hospitalization and outpatient transplant clinic visits. PATIENTS Thoracic transplant recipients who were initiated on DOACs between May 1, 2011, and March 1, 2015, at the University of Pittsburgh Medical Center were included. RESULTS A total of 37 patients were included in the analysis. A majority of the patients were lung transplant recipients (86.4%) with a median age of 60.7 years. Twenty-eight patients had a history of VTE. The primary indication for DOAC initiation was VTE (86.5%). Rivaroxaban (78.4%) was the most commonly utilized agent. Dose reductions for major drug interactions (37.8%), renal insufficiency (10.8%), or both (8.1%) occurred within the study. Two patients had breakthrough VTE during DOAC therapy. Eight bleeding events were reported in the cohort, one of which was considered a major bleed. There was no difference in the incidence of bleeding in patients with drug-drug interactions and without drug-drug interactions during DOAC therapy (26.0% vs 7.1%, P = .154). CONCLUSION Direct oral anticoagulant therapy was well tolerated by thoracic transplant recipients. Drug interactions and renal dose adjustments were common.

Abstract
Calcineurin inhibitors (CNIs) are the backbone of traditional immunosuppressive regimens for lung transplant recipients (LTR). The CNIs are both narrow therapeutic index drugs with significant interpatient and intrapatient variability that require therapeutic drug monitoring to ensure safety and effectiveness. We hypothesized that tacrolimus time-in-therapeutic range (TTR) affects acute and chronic rejection rates in LTRs. This was a single-center, observational, cross-sectional study of 292 adult LTRs. Subjects who received tacrolimus posttransplant for the first year were included. TTR was calculated at 1 year using protocol goal ranges (12-15 mg/mL months 0-6; 10-12 mg/mL for months 7-12). The primary outcome was acute cellular rejection (ACR) burden at 1 year. Chronic lung allograft dysfunction (CLAD), mortality, and infection rate were assessed as secondary outcomes at 1 year. Primary and secondary outcomes were assessed using logistic regression. Increasing TTR by 10% was associated with a significantly lower likelihood of high-burden ACR at 1 year on univariable (OR 0.46, 95% CI 0.40-0.54, P < .001) and multivariable (OR 0.64, 95% CI 0.47-0.86, P = .003) assessment, controlling for age and induction agent. Increasing TTR by 10% was also associated with lower rates of CLAD (P < .001) and mortality (P < .001) at 1 year. Prospective studies confirming these findings appear warranted.

Abstract
A systematic review of papers in English on post-transplant lymphoproliferative disorder (PTLD) in lung transplant recipients (LTR) using MEDLINE, EMBASE, SCOPUS, and Cochrane databases was performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations were strictly adhered to. Pooled odds ratios (pOR) were calculated from a random-effects model, and heterogeneity among studies was quantitated using I2 values. Fourteen studies published from 2005 to 2015 were included in the meta-analysis. One hundred and sixty-four lung transplant recipients were included. LTRs who received single vs bilateral were associated with a 7.67-fold risk of death after PTLD (6 studies with 64 LTRs; pOR 7.67 95% CI 1.98-29.70; P = .003). pOR of death for early onset PTLD (<1 year post-LT) vs late onset (>1 year post-LT) was not different (3 studies with 72 LTRS; pOR 0.62, 95% CI 0.20-1.86, P = .39). Standardized mean difference (SMD) in time from transplant to PTLD onset between LTRs who died vs alive was not different (9 studies with 109 LTRs; SMD 0.03, 95% CI -0.48-0.53, P = .92). Survival in polymorphic vs monomorphic PTLD and extranodal vs nodal disease was similar (4 studies with 31 LTRs; pOR 0.44, 95% CI 0.08-2.51; P = .36. 6 studies with 81 LTRs; pOR 1.05 95% CI 0.31-3.52, P = .94). This meta-analysis demonstrates that single LTRs are at a higher risk of death vs bilateral LTRs after the development of PTLD.

Abstract
BACKGROUND Cellular and molecular mechanisms of acute and chronic lung allograft rejection have yet to be clearly defined, and obliterative bronchiolitis (OB) remains the primary limitation to survival in lung transplant recipients (LTRs). We have previously shown that T-bet-deficient recipients of full major histocompatibility complex (MHC)-mismatched, orthotopic left lung transplants develop accelerated obliterative airway disease (OAD) in the setting of acute cellular rejection characterized by robust alloimmune CD8+ interleukin (IL)-17 and interferon (IFN)-γ responses that are attenuated with neutralization of IL-17. Azithromycin has been shown to be beneficial in some LTRs with bronchiolitis obliterans syndrome/OB. Here, we evaluated the effects of azithromycin on rejection pathology and T-cell effector responses in T-bet-/- recipients of lung transplants. METHODS Orthotopic left lung transplantation was performed in BALB/c → B6 wild type or BALB/c → B6 T-bet-/- strain combinations as previously described. Mice treated with azithromycin received 10 mg/kg or 50 mg/kg subcutaneously daily. Lung allograft histopathology was analyzed at day 10 or day 21 post-transplantation, and neutrophil staining for quantification was performed using anti-myeloperoxidase. Allograft mononuclear cells were isolated at day 10 for T-cell effector cytokine response assessment using flow cytometry. RESULTS We show that while azithromycin significantly decreases lung allograft neutrophilia and CXCL1 levels and attenuates allospecific CD8+ IL-17 responses early post-transplantation, OAD persists in T-bet-deficient mice. CONCLUSIONS Our results indicate that lung allograft neutrophilia is not essential for the development of OAD in this model and suggest allospecific T-cell responses that remain despite marked attenuation of CD8+ IL-17 are sufficient for obliterative airway inflammation and fibrosis.

Abstract
We present this observational study of lung transplant recipients (LTR) treated with carfilzomib (CFZ)-based therapy for antibody-mediated rejection (AMR) of the lung. Patients were considered responders to CFZ if complement-1q (C1q)-fixing ability of their immunodominant (ID) donor-specific anti-human leukocyte antibody (DSA) was suppressed after treatment. Treatment consisted of CFZ plus plasma exchange and immunoglobulins. Fourteen LTRs underwent CFZ for 20 ID DSA AMR. Ten (71.4%) of LTRs responded to CFZ. DSA IgG mean fluorescence intensity (MFI) fell from 7664 (IQR 3230-11 874) to 1878 (653-7791) after therapy (p = 0.001) and to 1400 (850-8287) 2 weeks later (p = 0.001). DSA C1q MFI fell from 3596 (IQR 714-14 405) to <30 after therapy (p = 0.01) and <30 2 weeks later (p = 0.02). Forced expiratory volume in 1s ( FEV1 ) fell from mean 2.11 L pre-AMR to 1.92 L at AMR (p = 0.04). FEV1 was unchanged after CFZ (1.91 L) and subsequently rose to a maximum of 2.13 L (p = 0.01). Mean forced expiratory flow during mid forced vital capacity (25-75) (FEF25-75 ) fell from mean 2.5 L pre-AMR to 1.95 L at AMR (p = 0.01). FEF25-75 rose after CFZ to 2.54 L and reached a maximum of 2.91 L (p = 0.01). Responders had less chronic lung allograft dysfunction or progression versus nonresponders (25% vs. 83%, p = 0.04). No deaths occurred within 120 days and 7 patients died post CFZ therapy of allograft failure. Larger prospective interventional studies are needed to further describe the benefit of CFZ-based therapy for pulmonary AMR.

Abstract
BACKGROUND Dual antiplatelet therapy is a mainstay of care for percutaneous coronary intervention (PCI) patients; however, uncertainty exists in real-world practice about comparative effectiveness and safety outcomes. OBJECTIVE To evaluate outcomes of different oral P2Y12 inhibitors in PCI patients. METHODS We retrospectively studied patients treated between July 1, 2010, and December 31, 2013. Patients received clopidogrel, prasugrel, ticagrelor, or more than 1 antiplatelet (switch) during PCI. Outcomes were evaluated for major adverse cardiovascular events (MACE) and bleeding at 1 year. Propensity score matching with Cox proportional hazards analysis was used to determine predictors of MACE and bleeding. RESULTS A total of 8127 patients were included: clopidogrel (n = 6872), prasugrel (n = 605), ticagrelor (n = 181), and switch (n = 469). Treatment with prasugrel was associated with the lowest risk of MACE using multivariate regression (odds ratio [OR] = 0.57; 95% CI = 0.36-0.92; P = 0.02). In the propensity score-matched analysis, only the prasugrel group was associated with a lower risk of MACE compared with the clopidogrel group. Clopidogrel was associated with the lowest risk of major bleeding using multivariate regression (OR = 0.64; 95% CI = 0.42-0.98; P = 0.042). Both ticagrelor (hazard ratio [HR] = 2.00; 95% CI = 1.11-3.59) and the switch groups (HR = 1.65; 95% CI = 1.09-2.50) were associated with a greater risk of major bleeding compared with clopidogrel. However, no differences were found in the propensity score-matched analysis. CONCLUSIONS Dual antiplatelet therapies differed in both MACE and bleeds in a real-world setting of PCI. Prasugrel was associated with fewer MACE, whereas clopidogrel had fewer major bleeding events.

Abstract
BACKGROUND: The usefulness of glucocorticoids after cardiac surgery with cardiopulmonary bypass has been a matter of debate for many years. Exposure to cardiopulmonary bypass evokes the systemic inflammatory response syndrome in patients undergoing cardiac surgery. Intravenous glucocorticoids have been used to reduce proinflammatory cytokine release, slow leukocyte migration, and decrease capillary leak associated with cardiopulmonary bypass. OBJECTIVE: To assess the impact of early postoperative hydrocortisone administration on duration of vasoactive medication administration and the incidence of postoperative atrial fibrillation in cardiac surgical patients after cardiopulmonary bypass. METHODS: A retrospective cohort study (between July 1, 2004, and June 30, 2008) was conducted at a large, university-affiliated, tertiary-care medical center. One-hundred forty-seven patients who underwent cardiac surgery with cardiopulmonary bypass, 72 of whom received at least 1 dose of hydrocortisone (treatment), and 75 similar patients who did not receive hydrocortisone (control), were randomly selected. RESULTS: Cardiopulmonary bypass and aortic cross-clamp times were similar between treatment and control groups (128 vs 124 minutes, p = 0.56; 103 vs 98 minutes, p = 0.39). Patients who received hydrocortisone had a significantly shorter time to discontinuation of all vasoactive medications (79.6 vs 21.1 hours, p < 0.001), and less postoperative atrial fibrillation (OR 0.28, 95% CI 0.14 to 0.56, p < 0.001). Patients in the treatment group experienced significantly more hyperglycemia (89 vs 71%, p = 0.006); however, major and minor bleeding or infection rates did not differ significantly between groups. CONCLUSIONS: Patients treated with hydrocortisone after cardiac surgery with cardiopulmonary bypass experienced a significantly shorter time to discontinuation of all vasoactive medications and less postoperative atrial fibrillation than patients not treated with hydrocortisone. These benefits came at the expense of significantly more hyperglycemia.

Abstract
Refractory acute cellular rejection (rACR) is associated with death and bronchiolitis obliterans syndrome (BOS) post-lung transplantation. We report the largest cohort of lung transplant recipients (LTRs) treated with rescue alemtuzumab for rACR or BOS. RACR outcomes included burden of ACR 30 days before and 180 days after rescue assessed by a novel composite rejection standardized score (CRSS, range 0-6) and freedom from ≥A2 ACR. BOS outcomes included freedom from BOS progression and FEV1 decline >10%. Univariate parametric and nonparametric statistical approaches were used to assess treatment response. Kaplan-Meier method with log rank conversion was used to assess freedom from events. Fifty-seven alemtuzumab doses (ACR 40 and BOS 17) given to 51 patients were included. Median time to rescue was 722 (IQR 42-1403) days. CRSS declined significantly (3 vs 0.67, P<0.001) after rescue. Freedom from ≥A2 was 62.5% in rACR. Freedom from BOS progression was 52.9% at 180 days in the BOS cohort. Freedom from FEV1 decline >10% was 70% in BOS grade 1 and 14.3% in advanced BOS grades 2-3. Infections developed in 72.5% and 76.5% of rACR and BOS groups. Rescue alemtuzumab appears useful for rACR. Patients with BOS 1 may have transient benefit, and patients with advanced BOS seem not to respond to alemtuzumab.

Abstract
Inhibition of the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway for immunosuppression in solid organ transplantation is appealing due to its specificity for immune cell function, particularly for JAK3. This is due to its unique association with only the common gamma chain (γc). The γc is an appealing immunosuppression target in transplantation because of the critically important lymphokines that act at it, including IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. Tofacitinib was initially purported to selectively inhibit solely JAK3, but subsequent analyses have also demonstrated its activity at the other members of the JAK family. Clinical outcomes have validated tofacitinib's pan-JAK activity in kidney transplantation after demonstrating an increased risk of infection and malignancy as compared to CNI-based regimens. After these trials, tofacitinib investigation for use in transplantation has effectively ceased. However, a post-hoc analysis has shed new light on the monitoring of tofacitinib exposure in order to predict infection and oncologic events. With new methods to monitor tofacitinib exposure, clinicians may be able to effectively reduce toxicities while providing a high level of immunosuppression. The purpose of this review to identify when, and for whom, JAK inhibitors may provide benefit in solid organ transplantation.

Abstract
BACKGROUND The development of human leukocyte antigen (HLA) antibody responses has been associated with worse clinical outcomes, such as bronchiolitis obliterans syndrome (BOS) and death, in lung transplant recipients (LTRs). However, the role of donor-specific HLA antibody (DSA) responses as a risk factor for poor outcomes remains controversial. METHODS We prospectively screened 445 LTRs for DSA at our institution at the time of surveillance bronchoscopies for the first 2 years after transplantation between 2003 and 2008, and evaluated clinical outcomes. For this purpose, we used the combination of panel-reactive antibodies (PRA) by enzyme-linked immunosorbent assay (ELISA) and the Luminex single-antigen bead (SAB) assay (One Lambda, Canoga Park, CA). RESULTS We detected de novo DSA (dnDSA) in 58 of 445 (13%) LTRs in our cohort. Freedom from BOS was significantly reduced in LTRs with dnDSA versus those without dnDSA (p < 0.001). Using a Cox proportional hazards model, the development of dnDSA was associated with a significantly increased hazard ratio (HR = 6.59 [4.53 to 9.59]; p < 0.001) for BOS and high-grade BOS (Stage ≥ 2) (HR = 5.76 [3.48 to 9.52]; p < 0.001). Freedom from death was significantly reduced in LTRs with dnDSA (p < 0.001), including mortality attributable to BOS (HR = 9.86 [4.91 to 19.78]; p < 0.001). CONCLUSIONS Taken together, our findings provide evidence that dnDSA is associated with accelerated BOS kinetics and severity, as well as death due to BOS after lung transplantation. In addition, these data support regular monitoring for the development of dnDSA in LTRs and underscore the need for novel strategies to mitigate the increased risk of poor outcomes associated with dnDSA.

Abstract
Evidence demonstrates a link between gastroesophageal reflux disease and chronic allograft dysfunction in lung transplant recipients. Delayed gastric emptying plays an important role in the occurrence of gastroesophageal reflux disease, with limited therapeutic options available for treatment. This retrospective observational study reports the use of domperidone in the management of delayed gastric emptying in lung transplant recipients. All patients who underwent lung transplant at our institution from 2007 to 2011 were reviewed and patients who were treated with domperidone were identified. Clinical symptoms and results of gastric emptying studies before and after initiation of domperidone were documented. QTc intervals were compared from before to after domperidone treatment at 3 months and at 1 year. Weight and dose-normalized calcineurin inhibitor troughs were evaluated before and 2 weeks after domperidone treatment was started. Of 82 patients, 24% (n = 20) had documented delayed gastric emptying and 35% (n = 29) had documented gastroesophageal reflux disease. Twelve of the 20 patients with delayed gastric emptying started treatment with domperidone. All patients responded symptomatically and 6 patients with gastric emptying studies before and after domperidone had documented improvement. No adverse effects were observed in any patients treated with domperidone. Results indicate that domperidone can be used safely and may improve symptoms related to delayed gastric emptying in lung transplant recipients.

Abstract
CONTEXT United Network for Organ Sharing (UNOS) 2011 bylaws and Centers for Medicare and Medicaid Services (CMS) regulations require a transplant pharmacist to be an active participant in the care of transplant patients. Transplant centers must be members in good standing with UNOS in order to perform transplants and must be certified by CMS to participate with Medicare. OBJECTIVE To identify characteristics of transplant-related pharmacy services at comprehensive transplant centers. DESIGN Survey regarding number of full-time equivalent (FTE) transplant pharmacists relative to number of annual transplants, transplant pharmacy model, roles in inpatient and clinic environments, training and specialization, funding sources, and expansion plans.Participants-Surveys were received from 14 (74%) of 19 identified centers that performed 200 to 400 kidney, liver, pancreas, simultaneous kidney/pancreas, heart, and lung transplants in 2010, representing 55 transplant pharmacists. RESULTS A mean of 325 transplants were performed in 2010 at the surveyed centers. The mean number of pharmacist FTEs was 4.25, which yielded a transplant-to-pharmacist ratio of 76.5. Nine centers (64%) practiced in a pharmacy specialist-only model, 12 (86%) practiced in a service-based fashion, and 10 (71%) saw patients in clinic. Fifty-four pharmacists (98%) had obtained a PharmD degree, 45 (82%) had completed 1 postgraduate year, and 28 (51%) had completed 2 postgraduate years of training. Nine centers (64%) funded FTEs solely through the pharmacy department. Ten centers (71%) plan to expand transplant pharmacist staff by a mean of 1.4 FTEs. CONCLUSIONS Large comprehensive transplant centers use multiple transplant pharmacists to perform patient care in the inpatient and outpatient environments. Most centers plan to expand FTEs. Further characterization of transplant pharmacists appears warranted.

Abstract
PURPOSE The most recent published evidence on the use of colloids versus crystalloids in critical care is reviewed, with a focus on population-dependent differences in safety and efficacy. SUMMARY Colloids offer a number of theoretical advantages over crystalloids for fluid resuscitation, but some colloids (e.g., hydroxyethyl starch solutions, dextrans) can have serious adverse effects, and albumin products entail higher costs. The results of the influential Saline Versus Albumin Fluid Evaluation (SAFE) trial and a subsequent SAFE subgroup analysis indicated that colloid therapy should not be used in patients with traumatic brain injury and other forms of trauma due to an increased mortality risk relative to crystalloid therapy. With regard to patients with severe sepsis, two meta-analyses published in 2011, which collectively evaluated 82 trials involving nearly 10,000 patients, indicated comparable outcomes with the use of either crystalloids or albumins. For patients requiring extracorporeal cardiopulmonary bypass (CPB) during heart surgery, the available evidence supports the use of a colloid, particularly albumin, for CPB circuit priming and postoperative volume expansion. In select patients with burn injury, the published evidence supports the use of supplemental colloids if adequate urine output cannot be maintained with a crystalloid-only rescue strategy. CONCLUSION The results of the SAFE trial and a subgroup analysis of SAFE data suggest that colloids should be avoided in patients with trauma and traumatic brain injury. There are minimal differences in outcome between crystalloids and hypo-oncotic or iso-oncotic albumin for fluid resuscitation in severe sepsis; in select populations, such as patients undergoing cardiac surgery, the use of iso-oncotic albumin may confer a survival advantage and should be considered a first-line alternative.

Abstract
OBJECTIVE To review available evidence about the safety and efficacy of alemtuzumab for induction of immunosuppression in heart transplant recipients. DATA SOURCES Searches of MEDLINE, EMBASE, and Cochrane databases were conducted. Key search terms included alemtuzumab, Campath-1H, CD52, lymphocyte, cytolytic, induction, immunosuppression, rejection, and cardiac transplantation. Additional pertinent data were identified through a search of abstracts from major transplant meetings. STUDY SELECTION AND DATA EXTRACTION All English-language articles and abstracts identified from the data sources were evaluated. All primary data were eligible for inclusion if they evaluated the safety or efficacy of alemtuzumab for induction of immunosuppression in heart transplant patients. One retrospective cohort, 1 case series, 1 case-control series, and 1 open-label trial were identified and included for review. DATA SYNTHESIS Acute cellular rejection occurs in 40% to 70% of heart transplant recipients within the first 6 months after transplant and is associated with significant morbidity and mortality. Depleting and nondepleting antibodies have displayed positive outcomes in inducing immunosuppression; however, the ideal induction strategy that balances efficacy and toxicity remains elusive. Alemtuzumab, a cytolytic anti-CD52 antibody, has been used to induce immunosuppression in kidney, pancreas, liver, intestine, and lung transplant recipients, and its use in heart transplant has been investigated. Studies of use of alemtuzumab to induce immunosuppression in heart transplant patients have shown low rates of rejection; however, it has not been directly compared with other immunosuppression-inducing agents and safety data are limited. CONCLUSIONS Although alemtuzumab may be a practical option for inducing immunosuppression, data are insufficient to recommend its routine use in deference to more established agents. Large, randomized clinical trials with extended durations of follow-up must be conducted to characterize its efficacy and safety further.

Abstract
OBJECTIVE To review the literature regarding current strategies and strategies under active development for the prevention and treatment of respiratory syncytial virus (RSV) infections in immunocompromised adults. DATA SOURCES The MEDLINE/PubMed, EMBASE, and Cochrane databases were queried from January 1980 to December 2011 for articles in English using these associated search terms: respiratory syncytial virus, ribavirin, intravenous immunoglobulin, IVIG, palivizumab, motavizumab, lung, pneumonia, transplantation, bone marrow, cancer, malignancy, and vaccine. STUDY SELECTION AND DATA EXTRACTION All relevant original studies, meta-analyses, systematic reviews, and review articles were assessed for inclusion. References from pertinent articles were examined for additional content not found during the initial search. DATA SYNTHESIS RSV in the immunocompromised adult can lead to significant morbidity and mortality. Treatment of RSV-infected adults is limited to antiviral therapy with ribavirin (aerosolized, oral, intravenous) and immunomodulation with intravenous immunoglobulins, corticosteroids, and palivizumab. Existing literature is predominantly case reports, small trials, and retrospective reviews of patients infected with RSV who have undergone lung or hematopoietic stem cell transplantation (HSCT). Palivizumab may be a viable option for prophylaxis against RSV in high-risk adults. Ribavirin is the most studied treatment option and should remain the backbone of multidrug regimens. Of the routes of administration, aerosolized ribavirin carries the preponderance of evidence and, though challenging, is preferred to limit systemic toxicities in the infected patient. Addition of an immunomodulator to ribavirin may provide a survival benefit over ribavirin alone; however, this has only been studied in a subset of HSCT patients with lower respiratory tract RSV infection. CONCLUSIONS Research most strongly supports the use of aerosolized ribavirin as the treatment strategy for immunocompromised adults with RSV. Addition of an immunomodulator may provide a survival benefit over ribavirin alone. Strategies and supportive data for the prevention of RSV infection in the high-risk adult are critically needed.

Abstract
OBJECTIVE To review the literature on the safety and effectiveness of neostigmine for the treatment of postoperative acute colonic pseudo-obstruction. DATA SOURCES The MEDLINE/PubMed, EMBASE, and Cochrane databases from November 1969 to November 2011 were queried for articles published in English, using the search terms neostigmine, acute colonic pseudo-obstruction, postoperative, surgery, and Ogilvie syndrome. STUDY SELECTION AND DATA EXTRACTION All relevant original studies, meta-analyses, systematic reviews, guidelines, and review articles were assessed for inclusion. References from pertinent articles were examined for additional content not found during the initial search. DATA SYNTHESIS Neostigmine may provide an effective treatment option for postoperative acute colonic pseudo-obstruction (ACPO) after conservative treatment measures have failed. One randomized controlled trial, 8 prospective and 3 retrospective observational studies, and 9 case reports evaluated neostigmine for ACPO. Included studies were limited by small sample sizes and heterogeneous populations not focused on postoperative patients, use of adjuvant agents, and lack of a consistent neostigmine regimen. CONCLUSIONS Neostigmine may be a safe and effective treatment option for postoperative ACPO; however, current data do not support its use as a first-line intervention. Prospective and retrospective studies have demonstrated improvement in clinical symptoms, reduction in time to resolution, and reduction of recurrence for patients who failed conservative management. Prospective clinical trial data that evaluate early neostigmine versus conservative management are critically needed to determine neostigmine's role as a first-line therapy for ACPO.

Abstract
Objective To provide a comprehensive review of the pharmacotherapy associated with the provision of mechanical circulatory support (MCS) to patients with end-stage heart failure and guidance regarding the selection, assessment, and optimization of drug therapy for this population. Data Sources: The MEDLINE/PubMed, EMBASE, and Cochrane databases were searched from 1960 to July 2010 for articles published in English using the search terms mechanical circulatory support, ventricular assist system, ventricular assist device, left ventricular assist device, right ventricular assist device, biventricular assist device, total artificial heart, pulsatile, positive displacement, axial, centrifugal, hemostasis, bleeding, hemodynamic, blood pressure, thrombosis, antithrombotic therapy, anticoagulant, antiplatelet, right ventricular failure, ventricular arrhythmia, anemia, arteriovenous malformation, stroke, infection, and clinical pharmacist. Study Selection And Data Extraction: All relevant original studies, metaanalyses, systematic reviews, guidelines, and reviews were assessed for inclusion. References from pertinent articles were examined for content not found during the initial search. Data Synthesis: MCS has advanced significantly since the first left ventricular assist device was implanted in 1966. Further advancements in MCS technology that occurred in the tatter decade are changing the overall management of end-stage heart failure care and cardiac transplantation. These pumps allow for improved bridge-to-transplant rates, enhanced survival, and quality of life. Pharmacotherapy associated with MCS devices may optimize the performance of the pumps and improve patient outcomes, as well as minimize morbidity related to their adverse effects. This review highlights the knowledge needed to provide appropriate clinical pharmacy services for patients supported by MCS devices. Conclusions: The HeartMate II clinical investigators called for the involvement of pharmacists in MCS patient assessment and optimization. Pharmacotherapeutic management of patients supported with MCS devices requires individualized care, with pharmacists as part of the team, based on the characteristics of each pump and recipient.

Abstract
Abstract A procoagulant effect may occur when enzymatic inhibitors of CYP2C9, 1A2, or 3A4 are therapeutically coadministered with warfarin. To our knowledge, there have been no case reports of such an interaction between warfarin and selegiline. We describe a case of a 49-year-old female who was taking warfarin for prevention of a venous thromboembolism after orthopedic surgery. During routine follow-up, the patient's international normalized ratio (INR) suddenly elevated to 9.0. Her INR had been subtherapeutic for 2 months prior despite escalating doses of warfarin. The only identifiable change to the patient's lifestyle or medications was the initiation of transdermal selegiline 5 days prior to this supratherapeutic INR. Recent laboratory tests revealed no significant abnormalities, with the exception of slightly depressed serum albumin. Her warfarin was held for 2 days, oral phytonadione 2.5 mg was given, and selegiline was held. The Drug Interaction Probability Scale revealed a probable drug-drug interaction between warfarin and selegiline. The likely mechanism of this interaction is selegiline-mediated moderate inhibition of CYP1A2 and weak or competitive inhibition of 2C9 and 3A4. Clinicians should be hypervigilant to this probable drug-drug interaction when initiating either therapy in a patient maintained on the opposing drug.

Abstract
The CardioWest temporary total artificial heart serves as a viable bridge to orthotopic heart transplantation in patients who are experiencing end-stage refractory biventricular heart failure. This device is associated with a low, albeit still substantial, risk of thrombosis. Platelet interactions with artificial surfaces are complex and result in continuous activation of contact proteins despite therapeutic anticoagulation. We searched the medical literature (publication dates, January 1962-October 2009) in order to evaluate means of mitigating adverse events that have occurred after implantation of the CardioWest temporary total artificial heart.We conclude that the use of a multitargeted antithrombotic approach, involving anticoagulation (bivalirudin and warfarin) and antiplatelet therapy (dipyridamole and aspirin), can mitigate the procoagulative effects of mechanical circulatory assist devices, particularly those that are associated with the CardioWest temporary total artificial heart. Careful monitoring with use of a variant multisystem approach, involving efficacy tests (thrombelastography and light transmittance aggregometry), safety tests (laboratory analyses), and warfarin genomics, may maximize the therapeutic actions and minimize the bleeding risks that are associated with the multitargeted antithrombotic approach. The development and monitoring of individualized antithrombotic regimens require that informed health professionals appreciate the complexities and grasp the hazards that are associated with these therapies.

Abstract
Objectives To describe the appropriateness and safety of induction immunosuppression for patients at risk for fatal rejection, and to describe the safety and effectiveness profiles of the induction regimens available in the United States. Data Sources MEDLINE/PubMed database, EMBASE database, Google Scholar; references from pertinent articles were also reviewed to identify additional data. Study Selection A systematic literature review from January 1, 1980, through June 30, 2008, was performed. Included articles ranged from case series to prospective randomized controlled double-blind placebo-controlled trials that detailed the following topics with respect to induction immunosuppression: risk of fatal rejection, renal sparing, malignancy, OKT3, rabbit or equine antithymocyte globulin, daclizumab, basiliximab, and alemtuzumab. Results Patients at highest risk for fatal rejection experienced a survival benefit from induction immunosuppression, whereas all other patients experienced no benefit or harm. Most of the early data detail positive experiences with polyclonal antibody regimens. Several newer trials compare the use of polyclonal strategies with the use of anti-CD25 targeted monoclonal antibodies. Few researchers have assessed the usefulness of an anti-CD52 approach. Overall, induction therapy remains a poorly studied and widely variable practice among the major US heart transplant centers. Conclusion At present, the unrestricted use of induction for all patients does not seem prudent. Induction should be individualized for each patient on the basis of a well-designed protocol, careful analysis of the transplant center's demographics, and the effectiveness and safety profiles of the regimens used.
