Rural-Urban Disparities in Colorectal Cancer Screening, Diagnosis, Treatment, and Survivorship Care: A Systematic Review and Meta-Analysis.

BACKGROUND: Rural residents have a higher prevalence of colorectal cancer (CRC) mortality compared to urban individuals. Policies have been aimed at improving access to CRC screening to reduce these outcomes. However, little attention has been paid to other determinants of CRC-related outcomes, such as stage at diagnosis, treatment, or survivorship care. The main objective of this analysis was to evaluate literature describing differences in CRC screening, stage at diagnosis, treatment, and survivorship care between rural and urban individuals. MATERIALS AND METHODS: We conducted a systematic review of electronic databases using a combination of MeSH and free-text search terms related to CRC screening, stage at diagnosis, treatment, survivorship care, and rurality. We identified 921 studies, of which 39 were included. We assessed methodological quality using the ROBINS-E tool and summarized findings descriptively. A meta-analysis was performed of studies evaluating CRC screening using a random-effects model. RESULTS: Seventeen studies reported disparities between urban and rural populations in CRC screening, 12 on treatment disparities, and 8 on staging disparities. We found that rural individuals were significantly less likely to report any type of screening at any time period (pooled odds ratio = 0.81, 95% CI, 0.76-0.86). Results were inconclusive for disparities in staging at diagnosis and treatment. One study reported a lower likelihood of use of CRC survivorship care for rural individuals compared to urban individuals. CONCLUSION: There remains an urgent need to evaluate and address CRC disparities in rural areas. Investigators should focus future work on assessing the quality of staging at diagnosis, treatment, and survivorship care in rural areas.

Characterization of direct oral anticoagulants use in adult hematopoietic stem cell transplant recipients.

Direct oral anticoagulants (DOACs) for venous thromboembolism (VTE) treatment are of interest in oncology due to ease of administration and lack of need for therapeutic monitoring compared to other anticoagulants. Data supporting their use in patients with hematologic malignancies post-hematopoietic stem cell transplant (HCT) are limited. The purpose of the study is to characterize DOAC use in HCT patients. This multicenter, retrospective cohort analysis included allogeneic and autologous HCT recipients. The primary outcome was major bleeding. Secondary outcomes included clinically relevant non-major bleeding (CRNMB)/minor bleeding and VTE recurrence. Of 126 patients, 91 (72.2%) patients received an autologous HCT, and 35 (27.8%) patients received an allo-HCT. No major bleeding occurred in either transplant recipient groups. In autologous HCT recipients, CRNMB/minor bleeding occurred in four (4.4%) patients and VTE recurrence occurred in one (1.1%) patient. For allogeneic HCT recipients, CRNMB/minor bleeding occurred in five (14.3%) patients and VTE recurrence occurred in two (5.7%) patients. For patients that experienced a CRNMB, five (100%) of the allogeneic HCT and two (50%) of the autologous HCT recipients were thrombocytopenic at the time of bleeding. Only 38.5% of patients who experienced a drug-drug interaction requiring DOAC dose adjustment received the appropriate dose adjustment. DOACs were associated with low rates of recurrent VTE and no major bleeding events, similar to published data on DOAC use in the general cancer patient population. This suggests that DOACs may be safe therapeutic options with proactive management of drug interactions and careful monitoring for bleeding events, especially in the allogeneic HCT population where minor bleeding rates were slightly higher.

Vaccine response after pneumococcal vaccination in allogeneic hematopoietic stem cell transplant recipients.

Current guidelines for vaccination in allogeneic hematopoietic stem cell transplant (HCT) recipients recommend initiation of pneumococcal vaccination series three to six months post-HCT, with most data supporting initiation at six months due to a more robust immune response. This single-center, retrospective, observational chart review aimed to evaluate the impact of initiating the pneumococcal vaccine series at three months post-HCT compared to six months post-HCT. The primary endpoints were defined as a percentage of patients with a serologic response of >1 and >1.3 µg/mL for over 50% of the defined serotypes. Outcomes showed no difference in immunologic response between the two groups.

Estimation of Kidney Function in Patients With Multiple Myeloma: Implications for Lenalidomide Dosing.

BACKGROUND: Lenalidomide is an immunomodulatory drug used to treat multiple myeloma that requires renal dosing adjustment based on Cockcroft-Gault (CG). Various equations to estimate kidney function exist and pose a potential issue with lenalidomide dosing. OBJECTIVE: The objective of this analysis was to evaluate the impact of estimating kidney function in newly diagnosed multiple myeloma patients with CG, Modification of Diet in Renal Disease (MDRD), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and their potential impact on lenalidomide dosing. METHODS: Data from 1121 multiple myeloma patients at the time of diagnosis acquired from the Mayo Clinic were used to calculate creatinine clearance (CrCl) using Cockcroft-Gault with actual body weight (CGABW), ideal body weight (CGIBW), or adjusted body weight (CGAdjBW); MDRD; and CKD-EPI for each subject. Discordances in dosing were then analyzed, and lenalidomide exposure was calculated for each subject to assess impact on pharmacokinetics of lenalidomide for patients who received discordant doses. RESULTS: Overall, approximately 16% of patients received a discordant dose when using MDRD or CKD-EPI instead of CGABW. The most common dose discordance was the decrease of a full dose of lenalidomide 25 mg when using CGABW down to 10 mg and when using MDRD or CKD-EPI with 53.8% to 55.6% of all discordances in this category. When assessing different body weights, the most common discordance was a decrease from 25 to 10 mg when using CGIBW instead of CGABW; the same trend was observed when using CGAdjBW instead as well. Patients were also at risk of over- or underexposure based on area under the concentration versus time curve (AUC) for discordant dosing. CONCLUSION AND RELEVANCE: A significant proportion of patients are at risk of under- or overdose of lenalidomide if CKD-EPI or MDRD are used instead of CGABW. Physicians should use CGABW when estimating renal function to dose lenalidomide.

Evaluation of direct oral anticoagulants versus low molecular weight heparins for venous thromboembolism treatment in patients with gastrointestinal malignancies.

BACKGROUND: Direct oral anticoagulant (DOAC) use in cancer-associated venous thromboembolism (CA-VTE) has increased due to updates in recent guidelines and literature. However, select guidelines caution against DOAC use in patients with gastrointestinal (GI) malignancies due to reported increased bleeding events. The objective of this study was to compare the safety and effectiveness of DOACs versus low-molecular-weight heparins (LMWHs) for CA-VTE treatment in patients with GI malignancies. PATIENTS AND METHODS: This multicenter, retrospective cohort study included patients with primary GI malignancies who received therapeutic anticoagulation with a DOAC or LMWH for CA-VTE between January 1, 2018, and December 31, 2019. The primary outcome was the incidence rate of bleeding events (major, clinically relevant non-major, or minor bleeding events) within a 12-month period following the initiation of therapeutic anticoagulation. The secondary endpoint was the incidence rate of recurrent VTE events within a 12-month period following the start of therapeutic anticoagulation. RESULTS: After screening, 141 patients met inclusion criteria. The incidence rate of all bleeding events significantly differed between DOAC (4.98 events/100 person-months) and LWMH (10.2 events/100 person-months) recipients. The corresponding incidence rate ratio (IRR) with the DOAC group serving as the reference was 2.05 (p = 0.01), with the majority of bleeds in both groups presenting as minor bleeds. No difference was found between the incidence rate of recurrent VTE within a 12-month period of starting therapeutic anticoagulation between groups (IRR 3.08, p = 0.06). CONCLUSION: Our results suggest that DOACs do not pose an additional bleeding risk compared to LMWH in patients with certain GI malignancies. Careful selection of DOAC therapy with respect to bleeding risk is still warranted.

Predictors of lenalidomide maintenance duration after autologous stem cell transplant in patients with multiple myeloma.

BACKGROUND: For patients with multiple myeloma (MM) who have undergone autologous stem cell transplant (auto-SCT), the immunomodulatory agent lenalidomide is a first-line option for maintenance therapy. Because longer durations of lenalidomide maintenance are associated with improved survival, identifying strategies to avoid premature cessation of maintenance is an important priority in the post-transplant setting. OBJECTIVES: The primary objective of this analysis was to identify specific clinical predictors of lenalidomide treatment duration that could guide optimal medication management. Key secondary objectives included predictors of intolerable toxicity, rationale for lenalidomide dose reduction/discontinuation, and characterization of dose adjustments. STUDY DESIGN: This retrospective, multi-center cohort study included adults with MM who underwent auto-SCT and initiated maintenance lenalidomide between 01/01/2012 and 02/28/2021. Variables assessed as potential predictors of maintenance duration or intolerable toxicity included age, body mass index (BMI), Eastern Cooperative Oncology Group (ECOG) performance status at time of auto-SCT, renal function, initial lenalidomide dose, use of combination maintenance therapy, and cytogenetic risk category. RESULTS: Among 299 patients included, the median age at time of auto-SCT was 62 years (range 30-77). The majority of patients had standard-risk cytogenetics (64%) and an ECOG performance status of 0 or 1 (72%). In the overall population, the median duration of maintenance was 1.3 years (range 0.3-8.6 years). The median initial dose of lenalidomide was 10 mg daily (range 2.5-25 mg). During the study period, 35% of patients had a dose reduction due to toxicity, 21% stopped lenalidomide due to disease progression, and 19% stopped due to toxicity. Multivariate linear regression analyses did not identify any significant predictors of lenalidomide duration or discontinuation due to intolerable toxicity. The most frequently reported toxicities leading to discontinuation were cytopenias, rash, and fatigue. CONCLUSION: This analysis did not identify any significant risk factors to predict the duration of lenalidomide maintenance or discontinuation for toxicity following auto-SCT in patients with MM. While limited by the retrospective design and relatively small sample size, our findings suggest that a priori lenalidomide dose reductions based on patient co-morbidities or performance status may not substantially affect the duration of lenalidomide maintenance.

Slowed progression: The utility of Test to Treat initiatives in improving the neglected inequities of COVID-19 among racially/ethnically minoritized groups.

In the United States, coronavirus disease 2019 (COVID-19) has resulted in more than 95 million infections and 1 million deaths (as of September 2022), with individuals of racially/ethnically minoritized groups being disproportionately represented among these numbers. Despite the apparent pandemic fatigue in many communities, systemic and structural racism continue to place racially/ethnically minoritized groups at a disadvantage for overcoming the virus, especially as it relates to receiving vaccinations and COVID-19 targeted therapeutics. Test to Treat programs have the potential to mitigate these disparities by rapidly identifying the presence of a COVID-19 infection and readily offering treatment options. Nonetheless, Test to Treat programs must be optimized to adequately address the limitations to care within racially/ethnically minoritized communities.

Effectiveness of letermovir for cytomegalovirus prophylaxis in allogeneic hematopoietic stem cell transplant recipients: A global systematic review.

OBJECTIVE(S): Letermovir (LET), a novel antiviral, has largely supplanted more traditional preemptive therapy (PET) for cytomegalovirus (CMV) prophylaxis in allogeneic hematopoietic stem cell transplant (allo-HCT) patients. Use of LET demonstrated efficacy against placebo in phase III randomized controlled trials, but is considerably more expensive than PET. This review aimed to evaluate the real-world effectiveness of LET in preventing clinically significant CMV infection (csCMVi) for allo-HCT recipients and related outcomes. DESIGN: A systematic literature review was performed using an a priori protocol using PubMed, Scopus, and ClinicalTrials.gov from January 2010 to October 2021. SETTING AND PARTICIPANTS: Studies were included if they met the following criteria: LET compared with PET, CMV-related outcomes, patients aged 18 years or older, and English language-only articles. Descriptive statistics were used to summarize study characteristics and outcomes. OUTCOME MEASURES: CMV viremia, csCMVi, CMV end-organ disease, graft-versus-host-disease, all-cause mortality. RESULTS: A total of 233 abstracts were screened, with 30 included in this review. Randomized trials demonstrated efficacy of LET prophylaxis in preventing csCMVi. Observational studies demonstrated varying degrees of effectiveness of LET prophylaxis compared with use of PET alone. All studies with a comparator group resulted in lower rates of csCMVi for patients using LET. Included studies varied widely by CMV viral load threshold cutoff and CMV test units, limiting synthesis of results owing to high heterogeneity. CONCLUSION: LET reduces risk of csCMVi, but lack of standardized clinical definitions on how to evaluate csCMVi and related outcomes largely prevent synthesis of results. Clinicians must consider this limitation in the context of evaluating the effectiveness of LET to other antiviral therapies, especially for patients at risk of late-onset CMV. Future studies should focus on prospective data collection through registries and concordance of diagnostic definitions to mitigate study heterogeneity.

Characterisation of infections in patients with acute myeloid leukaemia receiving venetoclax and a hypomethylating agent.

We investigated the incidence of invasive fungal infections (IFIs) and other infectious complications in patients receiving venetoclax and hypomethylating agent therapy for acute myeloid leukaemia (AML). This retrospective, multicentre cohort study included adult patients with AML who received at least one cycle of venetoclax and either azacitidine or decitabine between January 2016 and August 2020. The primary outcome was the incidence of probable or confirmed IFI. Secondary outcomes included antifungal prophylaxis prescribing patterns, incidence of bacterial infections, and incidence of neutropenic fever hospital admissions. Among 235 patients, the incidence of probable or confirmed IFI was 5.1%. IFI incidence did not differ significantly according to age, antifungal prophylaxis use, or disease status. In the subgroup of patients with probable or confirmed IFIs, six (50%) were receiving antifungal prophylaxis at the time of infection. The overall incidence of developing at least one bacterial infection was 33.6% and 127 (54%) patients had at least one hospital admission for febrile neutropenia. This study demonstrated an overall low risk of developing probable or confirmed IFI as well as a notable percentage of documented bacterial infections and hospital admissions due to neutropenic fever.

Brighter horizons: The necessity of concentrated sponsorship targeted toward minoritized student pharmacists.

Due to the effects of structural racism, disproportionately lower numbers of Black, Hispanic or LatinX, American Indian, and Alaska Native students pursue a career in pharmacy and successfully matriculate into the profession. Despite these disparities being present for many years, little progress has been achieved in diversifying the pharmacy profession, resulting in a persistent lack of diversity within pharmacy leadership across employers and pharmacy organizations. Consistent with recent recommendations for improving diversity in pharmacy, the PharmGradWishlist (PGWL) initiative was created as a way for practicing pharmacists and organizations to provide direct financial sponsorship to racially and ethnically minoritized trainees to offset costs incurred during training and during the transition from student to practicing pharmacist. Many of these costs, such as residency and fellowship application fees, job interview travel costs, board exam and licensing fees, and moving expenses, are not typically subsidized by federal student funding. Offsetting these costs is an important way to reduce barriers to entering the profession and postgraduate training, the latter of which may be particularly important in trainees' pursuit of academic and leadership positions in pharmacy. The initial development and advertisement of the initiative occurred through social media and the grassroots efforts of the PGWL team, a group of 10 volunteer pharmacists from across the country, and resulted in generous donations from a small proportion of practicing pharmacists nationwide. It is now time for the profession as a whole to embrace the role of direct sponsorship in improving diversity in the profession. We call upon pharmacists and pharmacy organizations to advocate for and participate in financial sponsorship of racially and ethnically minoritized trainees and pharmacists as a way to increase diversity and promote health equity.

Characterization of relapse patterns in patients with acute lymphoblastic leukemia treated with blinatumomab.

INTRODUCTION: Blinatumomab is a CD19/CD3 bispecific T-cell engager (BiTE) antibody that simultaneously binds CD19 on the surface of B-cells and CD3 on the surface of T-cells, resulting in tumor cell lysis. It is approved for the treatment of patients with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) and in patients with minimal residual disease after intensive induction chemotherapy. Relapse patterns after treatment with blinatumomab have not been well characterized. METHODS: We reviewed patients treated with blinatumomab with relapsed, refractory or minimal residual disease-positive B-ALL from 1 December 2014 to 31 December 2018 at a single academic medical center. Patient demographics, blast percentage prior to blinatumomab initiation, prior lines of therapy, blinatumomab treatment duration, sites of relapse, progression free survival, and overall survival were collected. RESULTS: A total of 20 patients were identified. Four (20%) patients developed extramedullary relapse following blinatumomab. The median time from treatment initiation to extramedullary relapse was 179 days (range 47-241). Sites of extramedullary relapse included the pancreas, adrenal gland, kidneys, liver, parotid gland, and brain. CONCLUSION: Extramedullary relapse occurs frequently following treatment of B-ALL with blinatumomab. Further studies aimed at preventing extramedullary relapse following blinatumomab treatment are warranted.

Real-World Toxicity Experience with BRAF/MEK Inhibitors in Patients with Erdheim-Chester Disease.

BACKGROUND: Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis. The BRAF inhibitor vemurafenib is approved by the U.S. Food and Drug Administration (FDA) for patients with ECD harboring a BRAF V600E mutation. Successful treatment has also been reported with MEK-targeted therapies, likely because of the fact that BRAF mutant-negative patients harbor MEK pathway alterations. In our Rare Tumor Clinic, we noted that these patients have frequent drug-related toxicity, consistent with previous reports indicating the need to markedly lower doses of interferon-alpha when that agent is used in these patients. PATIENTS AND METHODS: We performed a review of ten patients with ECD seen at the Rare Tumor Clinic at University of California San Diego receiving 16 regimens of targeted BRAF, MEK, or combined therapies. RESULTS: The median age of the ten patients with ECD was 53 years (range, 29-77); seven were men. The median dose percentage (percent of FDA-approved dose) tolerated was 25% (range, 25%-50%). The most common clinically significant adverse effects resulting in dose adjustments of targeted therapies were rash, arthralgias, and uveitis. Renal toxicity and congestive heart failure were seen in one patient each. In spite of these issues, eight of ten patients (80%) achieved a partial remission on therapy. DISCUSSION: Patients with ECD appear to require substantially reduced doses of BRAF and MEK inhibitors but are responsive to these lower doses.

Safety and efficacy of direct oral anticoagulants for venous thromboembolism and stroke prophylaxis in patients with hematologic malignancies.

PURPOSE: Low-molecular-weight heparins are currently the recommended antithrombotic therapy for treatment and prevention of malignancy-related venous thromboembolism. Currently, the evidence evaluating direct oral anticoagulants versus low-molecular-weight heparins or a vitamin K antagonist in cancer patients with hematologic malignancies is limited. We evaluated the safety and efficacy of direct oral anticoagulants for venous thromboembolism treatment or stroke prevention for non-valvular atrial fibrillation in patients with hematologic malignancies. METHODS: This was a retrospective evaluation of adult patients with hematologic malignancies who received at least one dose of the Food and Drug Administration-approved direct oral anticoagulant for venous thromboembolism treatment or stroke prevention. We determined the frequency of major bleeding events, non-major bleeding events, stroke, systemic embolism, appropriateness of initial direct oral anticoagulant doses, holding practices prior to procedures, and the rate of all-cause mortality. An analysis was also performed to compare the incidence of bleeding between patients with a history of hematopoietic stem cell transplant to non-transplant patients. RESULTS: A total of 103 patients were identified, with the majority of patients receiving rivaroxaban for venous thromboembolism treatment. Major bleeding events occurred in four patients and no fatal bleeding events occurred. Non-major bleeding occurred in 29 patients, most commonly epistaxis and bruising. Two patients experienced a systemic embolism while on direct oral anticoagulant therapy. CONCLUSION: Direct oral anticoagulants may be a safe and effective alternative for anticoagulation therapy in patients with hematologic malignancies. However, larger prospective studies comparing direct oral anticoagulants to low-molecular-weight heparins or vitamin K antagonists are warranted to compare efficacy and safety outcomes in this patient population.

Pegaspargase-induced hypertriglyceridemia in a patient with acute lymphoblastic leukemia.

Pegaspargase, a long acting formulation of L-asparaginase, is an asparagine specific enzyme that selectively kills leukemic cells by depleting plasma asparagine. Pegaspargase is FDA approved for the first-line treatment of adult acute lymphoblastic leukemia and is a critical component of numerous multi-chemotherapeutic regimens. Pegaspargase is associated with well-described toxicities including hypersensitivity reactions, hepatotoxicity, and thrombosis. However, hypertriglyceridemia is a much rarer complication of pegaspargase and has only been described in a limited number of reports. We present a case of severe hypertriglyceridemia after a single dose of pegaspargase. The patient was re-challenged with pegaspargase and again developed hypertriglyceridemia which was complicated by pancreatitis. Here, we summarize published reports and a literature review describing the incidence of pegaspargase-induced hypertriglyceridemia in common acute lymphoblastic leukemia protocols.

Evaluation of pharmacist interventions in a head and neck medical oncology clinic.

INTRODUCTION: Head and neck cancers (HNC) are a complex and heterogeneous group of cancers, often necessitating a multidisciplinary approach across the care continuum. Oncology pharmacists are uniquely qualified to play a vital role on a multidisciplinary team and provide specialized care to optimize medication therapy. METHODS: This was a retrospective chart review evaluating the role of a board-certified oncology pharmacist in the head and neck oncology clinic at an academic, comprehensive cancer center from April 2017 through March 2018. The primary objective of the study was to describe the types of interventions made by the oncology pharmacists. Secondary objectives included quantifying time spent on patient education and number of prescriptions sent to pharmacies. RESULTS: The pharmacist had 873 encounters with 151 patients, resulting in 2080 interventions. Approximately 57% of the interventions were performed in the clinic. Patient education (58%), facilitation of new prescriptions or refill requests (49.9%), and supportive care management (32.6%) were the most frequent interventions. The oncology pharmacist spent 154.1 h on patient education and sent 811 prescriptions to pharmacies, with 63.6% of prescriptions sent to the institution's cancer center pharmacy. CONCLUSION: The incorporation of an oncology pharmacist in the HNC team optimized patient care through comprehensive and timely interventions across the care continuum. Our study is the first to highlight the vital role oncology pharmacists have in improving the overall quality of care of HNC patients. Future directions include exploring the impact of oncology pharmacist interventions on select Quality Oncology Practice Initiative measures by the American Society of Clinical Oncology.

Characterization of collaborative practice agreements held by hematopoietic stem cell transplant pharmacists.

BACKGROUND: Current workforce shortages within the hematopoietic stem cell transplant field necessitate capitalizing on the role of oncology-trained pharmacists. Working within an agreed-upon protocol, pharmacists are able to expand patient care delivery through optimal medication therapy management. METHODS: An electronic survey was developed by the Advocacy & Policy Working Committee of the American Society for Blood and Marrow Transplantation Pharmacy Special Interest Group and distributed to pharmacists involved in the care of hematopoietic stem cell transplant patients. The primary objective was to assess the current state of collaborative practice agreements in the hematopoietic stem cell transplant setting. RESULTS: Forty-eight responses representing 41 institutions were returned. Respondents were mostly female (67%) and practiced in the adult setting (83%). Reponses represented a range of practice experience in hematopoietic stem cell transplant with the majority of the hematopoietic stem cell transplant positions (83%) funded by the department of pharmacy at an academic medical center. Of the 48 responses, 22 (46%) respondents reported having collaborative practice agreements in place; 10 (21%) respondents did not currently have collaborative practice agreements, but were planning to implement them; and 16 (33%) respondents did not have collaborative practice agreements at their institution. Clinical activities performed under a collaborative practice agreement included medication selection and dosing modifications, therapeutic drug monitoring, supportive care management, and management of comorbid conditions and chronic diseases. The most commonly cited barrier to establishing collaborative practice agreements was the inability to secure reimbursement for services provided. No respondents reported a negative impact on job satisfaction. CONCLUSIONS: The results of this survey provide the pharmacy community with a robust understanding of the current landscape of hematopoietic stem cell transplant pharmacy collaborative practice agreements.

Topical cidofovir-induced acute kidney injury in two severely immunocompromised patients with refractory multidrug-resistant herpes simplex virus infections.

Cidofovir, a nucleoside analog of deoxycytidine monophosphate, is a water-soluble polar molecule that exhibits antiviral activity against a broad range of DNA viruses. Cidofovir for injection is approved for the treatment of cytomegalovirus retinitis in patients with acquired immune deficiency syndrome. The safety and efficacy of topical cidofovir has been described in a limited number of patients. We present two cases of multidrug-resistant herpes simplex virus infections that responded to topical cidofovir therapy yet resulted in irreversible acute kidney injury.

General and Virus-Specific Immune Cell Reconstitution after Double Cord Blood Transplantation.

Cord blood transplantation (CBT) is curative for many patients with hematologic malignancies but is associated with delayed immune recovery and an increased risk of viral infections compared with HLA-matched bone marrow or peripheral blood progenitor cell transplantation. In this study we evaluated the significance of lymphocyte recovery in 125 consecutive patients with hematologic malignancies who underwent double-unit CBT (DUCBT) with an antithymocyte globulin-containing regimen at our institution. A subset of 65 patients was prospectively evaluated for recovery of T, natural killer (NK), and B cells, and in 46 patients we also examined viral-specific T cell recovery against adenovirus, Epstein-Barr virus, cytomegalovirus, BK virus, respiratory syncytial virus, and influenza antigen. Our results indicate that in recipients of DUCBT, the day 30 absolute lymphocyte count is highly predictive of nonrelapse mortality and overall survival. Immune recovery post-DUCBT was characterized by prolonged CD8+ and CD4+ T lymphopenia associated with preferential expansion of B and NK cells. We also observed profound delays in quantitative and functional recovery of viral-specific CD4+ and CD8+ T cell responses for the first year post-CBT. Taken together, our data support efforts aimed at optimizing viral-specific T cell recovery to improve outcomes post-CBT.

The impact of pre-transplant valganciclovir on early cytomegalovirus reactivation after allogeneic hematopoietic stem cell transplantation.

Cytomegalovirus reactivation is a common complication of allogeneic hematopoietic stem cell transplant. The use of pre-transplant valganciclovir during the conditioning regimen followed by preemptive therapy has been used in an attempt to reduce the rate of early cytomegalovirus reactivation, but efficacy data are lacking. In this retrospective study, we evaluated the impact of pre-transplant valganciclovir during the conditioning regimen followed by a preemptive approach on the rate of early cytomegalovirus reactivation through day 100. The rate of cytomegalovirus reactivation through day 100 was 41% in the no-valganciclovir group compared to 46% in the valganciclovir group (p = 0.4). Interestingly, median time to cytomegalovirus reactivation was earlier in the no-valganciclovir group compared to the valganciclovir group (26 vs. 34 days; p = 0.008) and there was a trend toward a higher rate of cytomegalovirus disease through day 100 in the no-valganciclovir group (0.7% valganciclovir vs. 4% no-valganciclovir; p = 0.1). Day 100 survival was similar between the groups (90% valganciclovir vs. 91% no-valganciclovir; p = 0.8). Although the time to cytomegalovirus reactivation is significantly longer in the valganciclovir group, this did not impact the rate of cytomegalovirus reactivation or survival by day 100 suggesting that other strategies need to be explored.
