RESUMEN

Background: Iron deficiency anemia (IDA) is a common cause of fatigue and impaired quality of life. The present study aimed to evaluate the impact of intravenous iron supplementation with ferric carboxymaltose (FCM) on fatigue, physical function, and general health among patients with IDA attending routine clinical care. Methods: This was a prospective, single arm, observational study of adult patients prescribed with intravenous FCM for the treatment of IDA during routine clinical care. We used Patient-Reported Outcomes Measurement Information System (PROMIS) instruments to evaluate fatigue (PROMIS Short Form v1.0 13a [FACIT-Fatigue]), general health status (PROMIS Scale v1.2), and physical function (PROMIS Short Form v2.0 4a) before and at 3 and 6 months after FCM treatment. Results: A total of 152 patients were enrolled. Mean age was 47.4 ± 16.0 years and 82.2% were female. Mean serum hemoglobin was 10.2 ± 1.4 g/dL at baseline. All patients were treated with at least one FCM dose at baseline, with 77.6% receiving a two-dose treatment course. The mean baseline FACIT-Fatigue score was 61.0 ± 9.0, improving significantly to 50.2 ± 9.5 at 3 months after FCM treatment. A minimum 5-point improvement, pre-defined as clinically meaningful, was seen in the FACIT-Fatigue, PROMIS Global Physical Health, Global Mental Health and PROMIS Physical Function scores for 72.7%, 52.8%, 41.7% and 39.8% of patients at 3 months (p < 0.0001 for each change from baseline), with statistically significant improvement continuing at 6 months. Mean serum hemoglobin was significantly increased at both 3 and 6 months (12.8 g/dL [N = 44] and 12.4 g/dL [N = 54], respectively). Conclusion: IDA patients attending routine clinical practice reported substantial levels of fatigue and impairments in physical function and global health prior to intravenous iron treatment. Patients experienced significant improvements in fatigue symptoms, physical function, and global health at 3 months after treatment with FCM, which were sustained at 6 months.

RESUMEN

Background: An antithrombotic stewardship program was implemented to reduce IV DTI use and increase fondaparinux and direct oral anticoagulant (DOAC) use for suspected or confirmed Heparin-induced thrombocytopenia (HIT). Objectives: This study evaluated the impact of an antithrombotic stewardship program on IV DTI utilization in patients with HIT. Methods: A retrospective analysis of adults receiving IV DTIs or fondaparinux from July 2016 to July 2017 (pre-stewardship) and October 2017 to July 2019 (post-stewardship) was conducted. Results: The median duration of IV DTI administration was not significantly different in HIT-negative patients between the pre- and post-stewardship cohorts (1.6 days (25th percentile (p25), 75th percentile (p75): .5, 3.3) vs 1.7 days (p25, p75: .9, 3.9), P = .31). The median duration of IV DTI administration in HIT-positive patients was 9.9 days (p25, p75: 7.6, 21.0) pre-stewardship and 7.3 days (p25, p75: 4.8, 16.5) post-stewardship (P = .18). For HIT-positive patients, the time from HIT diagnosis to discharge was 12.8 days (p25, p75: 8.9, 24.9) and 9.2 days (p25, p75: 4.0, 18.1) in the pre- and post-stewardship cohorts, respectively (P = .07). Fondaparinux and DOAC prescribing rates were 40.7% and 62.2% in the pre- and post-stewardship cohorts, respectively (P = .09). The percentage of patients with no contraindications to IV DTI alternatives receiving these agents increased from 31.2% to 78.6% (P = .01) following stewardship implementation. Conclusions: Intravenous DTI alternative utilization increased significantly after stewardship implementation. Stewardship implementation was associated with a non-statistically significant trend towards decreased IV DTI utilization and decreased length of stay for HIT-positive patients.

RESUMEN

Purpose: We report the first case of ocular involvement in TEMPI syndrome, a rare disease characterized by telangiectasias, elevated erythropoietin with erythrocytosis, monoclonal gammopathy, perinephric fluid collections, and intra-pulmonary shunting. Observations: A 64-year-old Caucasian man with history of TEMPI syndrome presented with subacute bilateral painless vision loss. Ocular examination showed chronic retinal ischemia with microvascular damage, which was likely associated with the chronic systemic hypoxemia, and spontaneous wax and wane of cystoid macular edema, presumedly related to the systemic bortezomib treatment. Conclusions and importance: Our case demonstrates that pathologic retinal vascular changes could be seen in association with TEMPI syndrome and suggests that a comprehensive ophthalmological examination may be beneficial for these patients.

RESUMEN

Immune checkpoint blockade has demonstrated durable clinical benefits in a variety of malignancies. These immune checkpoint inhibitors (ICIs) produce unwanted autoimmune reactions due to an impaired self-tolerance. Hematologic immune-related adverse events (heme-irAEs) have been increasingly reported in the literature with a reported fatality rate of 12%. In this review, we illustrate 3 cases treated at Johns Hopkins Hospital for ICI-induced agranulocytosis, aplastic anemia, and thrombocytopenia. We then summarize the available evidence regarding the incidence and prevalence of heme-irAEs. We identified immune thrombocytopenia and hemolytic anemia as the most commonly reported heme-irAEs which are more commonly observed with nivolumab therapy. Median time to onset of heme-irAEs varies between patients but occurs earlier with CTLA-4 inhibitors than with anti-PD-L1/PD-1 agents. We also describe the current challenges regarding the recurrence of heme-irAEs despite immune checkpoint blockade termination. We provide the available evidence supporting a mixed T-cell and B-cell immune-mediated response. Finally, we review the treatment algorithm of these complications and provide treatment alternatives to steroid-refractory cases.

RESUMEN

Immune checkpoint inhibitors (ICIs) are the standard of care for the treatment of several cancers. While these immunotherapies have improved patient outcomes in many clinical settings, they bring accompanying risks of toxicity, specifically immune-related adverse events (irAEs). There is a need for clear, effective guidelines for the management of irAEs during ICI treatment, motivating the Society for Immunotherapy of Cancer (SITC) to convene an expert panel to develop a clinical practice guideline. The panel discussed the recognition and management of single and combination ICI irAEs and ultimately developed evidence- and consensus-based recommendations to assist medical professionals in clinical decision-making and to improve outcomes for patients.

RESUMEN

ABSTRACT: Medical diagnosis and therapy often rely on laboratory testing. We observed mistaken testing in evaluations for hemophagocytic lymphohistiocytosis (HLH) that led to delays and adverse outcomes. Physicians were mistakenly ordering interleukin-2 and quantitative natural killer cell flow cytometry, rather than soluble interleukin 2 receptor (sIL2R) or qualitative natural killer functional tests in the evaluation of patients suspected to have HLH.We initiated a prospective quality improvement project to reduce mistaken testing, reduce delays in correct testing due to mistaken ordering, and improve HLH evaluations. This consisted of provider education, developing an evaluation algorithm, and ultimately required systems interventions such as pop-ups and removal of the mistaken tests from the electronic ordering catalog.Active education reduced mistaken testing significantly in HLH evaluations from baseline (73.3% vs 33.3%, P = .003, relative risk reduction (RRR) 54.5%), but failed to meet the pre-specified RRR cutoff for success (70%). Education alone did not significantly reduce the proportion of HLH evaluations with delays in sIL2R testing (23.3% vs 7.4%, P = .096). Mistaken testing increased after the active intervention ended (33.3% vs 43.5%, P = .390, with RRR 40.7% from baseline. Mistaken test removal was successful: mistaken testing dropped to 0% (P < .001, RRR 100%), saved $14,235 yearly, eliminated delays in sIL2R testing from mistaken testing (23.3% vs 0%, P = .008), and expedited sIL2R testing after admission for HLH symptoms (14.6 days vs 3.8 days, P = .0012). These data show systems controls are highly effective in quality improvement while education has moderate efficacy.

RESUMEN

Introduction: The newest intravenous (IV) iron products show an improved safety profile over predecessors, allowing for the rapid administration of relatively high doses. Ferric derisomaltose (FDI; also known as iron isomaltoside), ferric carboxymaltose (FCM), and ferumoxytol (FER), are successful treatments for iron deficiency (Europe; FDI and FCM) and iron deficiency anemia (US; FDI, FCM, and FER).Areas covered: This review focusses on the chemistry and structure of FDI, FCM, and FER, and on three key aspects of IV iron safety: (1) hypersensitivity; (2) hypophosphatemia and sequelae; (3) cardiovascular safety.Expert opinion: Although the safety of modern IV iron has improved, immediate infusion reactions and the development of hypophosphatemia must be appreciated and recognized by those who prescribe and administer IV iron. Immediate infusion reactions can occur with any IV iron and are usually mild; severe reactions - particularly anaphylaxis - are extremely rare. The recognition and appropriate management of infusion reactions is an important consideration to the successful administration of IV iron. Severe, persistent, hypophosphatemia is a specific side effect of FCM. No cardiovascular safety signal has been identified for IV iron. Ongoing trials in heart failure will provide additional long-term efficacy and safety data.

RESUMEN

OBJECTIVES: Medicare Part B payment methods incentivize the use of more expensive injectable and infused drugs. We examined prescribing patterns in the context of intravenous (IV) iron, for which multiple similarly safe and efficacious formulations exist, with wide variations in price. STUDY DESIGN: We conducted a retrospective cohort analysis of IV iron utilization and payment in the Medicare population between 2015 and 2017. METHODS: This analysis used a national, random 20% sample of Medicare fee-for-service beneficiaries with Part B claims for IV iron between January 2015 and December 2017-a period before, during, and after a national shortage of iron dextran. This sample included 66,710 Medicare fee-for-service beneficiaries with at least 1 Part B claim for IV iron. RESULTS: The greatest increase in utilization occurred in the most expensive iron formulation, ferric carboxymaltose; its market share rose from 27.4% of use in 2015 to 47.7% in 2017. The use of a less expensive formulation, iron dextran, decreased from 26.7% to 18.7% over the same period. An alternative payment model in Maryland hospitals was associated with markedly less utilization of ferric carboxymaltose, accounting for 4.7% of IV iron utilization in Maryland hospitals. CONCLUSIONS: There was an increase in the dispensing of a higher-priced IV iron formulation associated with a shortage of a less expensive drug that persisted once the shortage ended. These findings in IV iron have broader implications for Part B drug payment policy because the price of the drug determines the physician and health system payment.

RESUMEN

Systems-based hematology is dedicated to improving care delivery for patients with blood disorders. First defined by the American Society of Hematology in 2015, the idea of a systems-based hematologist arose from evolving pressures in the health care system and increasing recognition of opportunities to optimize the quality and cost effectiveness of hematologic care. In this review, we begin with a proposed framework to formalize the discussion of the range of initiatives within systems-based hematology. Classification by 2 criteria, project scope and method of intervention, facilitates comparison between initiatives and supports dialogue for future efforts. Next, we present published examples of successful systems-based initiatives in the field of hematology, including efforts to improve stewardship in the diagnosis and management of complex hematologic disorders (eg, heparin-induced thrombocytopenia and thrombophilias), the development of programs to promote appropriate use of hematologic therapies (eg, blood products, inferior vena cava filters, and anticoagulation), changes in care delivery infrastructure to improve access to hematologic expertise (eg, electronic consultation and disorder-specific care pathways), and others. The range of projects illustrates the broad potential for interventions and highlights different metrics used to quantify improvements in care delivery. We conclude with a discussion about future directions for the field of systems-based hematology, including extension to malignant disorders and the need to define, expand, and support career pathways.

RESUMEN

Cutaneous T cell lymphomas (CTCL) comprise of a heterogeneous group of non-Hodgkin lymphomas derived from skin-homing T cells. Variation in clinical presentation and lack of definitive molecular markers make diagnosis especially challenging. The biology of CTCL remains elusive and clear links between genetic aberrations and epigenetic modifications that would result in clonal T cell expansion have not yet been identified. Nevertheless, in recent years, next generation sequencing (NGS) has enabled a much deeper understanding of the genomic landscape of CTCL by uncovering aberrant genetic pathways and epigenetic dysregulations. Additionally, single cell profiling is rapidly advancing our understanding of patients-specific tumor landscape and its interaction with the surrounding microenvironment. These studies have paved the road for future investigations that will explore the functional relevance of genetic alterations in the progression of disease. The ultimate goal of elucidating the pathogenesis of CTCL is to establish effective therapeutic targets with more durable clinical response and treat relapsing and refractory CTCL.

RESUMEN

Mycosis fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma (CTCL), and Sézary syndrome (SS) is a rare erythrodermic and leukemic subtype of CTCL characterized by significant blood involvement. Although early-stage disease can be effectively treated predominantly with skin-directed therapies, systemic therapy is often necessary for the treatment of advanced-stage disease. Systemic therapy options have evolved in recent years with the approval of novel agents such as romidepsin, brentuximab vedotin, and mogamulizumab. These NCCN Guidelines Insights discuss the diagnosis and management of MF and SS (with a focus on systemic therapy).

RESUMEN

PURPOSE: To assess the efficacy of pembrolizumab in patients with advanced relapsed or refractory mycosis fungoides (MF) or Sézary syndrome (SS). PATIENTS AND METHODS: CITN-10 is a single-arm, multicenter phase II trial of 24 patients with advanced MF or SS. Patients were treated with pembrolizumab 2 mg/kg every 3 weeks for up to 24 months. The primary end point was overall response rate by consensus global response criteria. RESULTS: Patients had advanced-stage disease (23 of 24 with stage IIB to IV MF/SS) and were heavily pretreated with a median of four prior systemic therapies. The overall response rate was 38% with two complete responses and seven partial responses. Of the nine responding patients, six had 90% or more improvement in skin disease by modified Severity Weighted Assessment Tool, and eight had ongoing responses at last follow-up. The median duration of response was not reached, with a median response follow-up time of 58 weeks. Immune-related adverse events led to treatment discontinuation in four patients. A transient worsening of erythroderma and pruritus occurred in 53% of patients with SS. This cutaneous flare reaction did not result in treatment discontinuation for any patient. The flare reaction correlated with high PD-1 expression on Sézary cells but did not associate with subsequent clinical responses or lack of response. Treatment responses did not correlate with expression of PD-L1, total mutation burden, or an interferon-γ gene expression signature. CONCLUSION: Pembrolizumab demonstrated significant antitumor activity with durable responses and a favorable safety profile in patients with advanced MF/SS.

RESUMEN

Allogeneic blood or marrow transplantation (allo-BMT) remains the only treatment for chronic lymphocytic leukemia (CLL) with curative potential. Although post-transplantation cyclophosphamide (PTCy) reduces allo-BMT toxicity by decreasing the risk of graft-versus-host disease (GVHD), its effect on CLL allo-BMT outcomes is unknown. We studied 64 consecutive patients with CLL who underwent nonmyeloablative (NMA) haploidentical allo-BMT at Johns Hopkins Sidney Kimmel Comprehensive Cancer Center. In this cohort, the 4-year overall survival was 52% (95% confidence interval [CI], 40% to 68%), and progression-free survival was 37% (95% CI, 26% to 54%). Six patients experienced engraftment failure. PTCy prophylaxis was associated with a modest cumulative incidence of 1-year grade II-IV acute GVHD (27%; %95% CI, 15% to 38%) and %%%2-year chronic GVHD (17%; 95% CI, 7% to 26%). We demonstrate that NMA haploidentical allo-BMT with PTCy is a safe and effective treatment option.

RESUMEN

Synthetic cannabinoids have become increasingly popular drugs of abuse due to low cost and inability to detect these substances on routine drug screenings. In the United States, incidence of synthetic cannabinoid contamination with long-acting anticoagulant rodenticides (LAARs) resulting in coagulopathy and bleeding complications has been described.We sought to describe the natural history, management approach, and outcomes of bleeding secondary to synthetic cannabinoid-associated LAAR toxicity in an observational case series of patients evaluated at an urban academic medical system.We conducted an observational study of patients with suspected exposure to LAAR-contaminated synthetic cannabinoids and associated bleeding treated within the Johns Hopkins Health System.In this 16 subject cohort, hematuria was the most common bleeding symptom at presentation. The majority of the cohort (75%) had international normalized ratio (INR) > 9.6 at presentation. Of the 13 patients with brodifacoum testing, 12/13 (92%) were positive. Twelve patients (75%) had at least 1 INR value below 2 within 24 hours of the first INR measurement. Of this cohort, 1/16 (6%) died in hospital. The median length of hospital stay was 4 days, (interquartile range = 3-6). The average cost of pharmacological treatment for coagulopathy during inpatient hospitalization was $5300 (range, $2241-$8086).In patients presenting with unexplained coagulopathy it is important for emergency department providers to consider LAAR intoxication and consider formal testing for brodifacoum to assist with treatment planning. Use of a standardized management algorithm including intravenous/oral vitamin K, judicious use of blood products and close laboratory monitoring is essential to optimizing outcomes.

RESUMEN

With timely and effective treatment, most patients with thrombotic thrombocytopenic purpura (TTP) survive the acute TTP episode. In addition to the risk of relapse, TTP survivors have higher all-cause mortality than the general population and increased rates of chronic morbidities, including hypertension, depression, and mild cognitive impairment. We conducted this retrospective-prospective cohort study to determine the incidence and prevalence of stroke after recovery from acute TTP and to test the hypothesis that lower ADAMTS13 activity after recovery from TTP is associated with an increased risk of stroke during remission. Of 170 consecutive patients treated for TTP at The Johns Hopkins Hospital from 1995 through 2018, 14 (8.2%) died during the index episode and 19 were observed for less than 1 month after recovery. Of the remaining 137 patients, 18 (13.1%) developed stroke unrelated to an acute TTP episode over a median observation period of 3.08 years, which is fivefold higher than the expected prevalence of 2.6% from an age- and sex-matched reference population (P = .002). ADAMTS13 activity during remission was measured in 52 patients and was >70% in 44.2%, 40% to 70% in 23.1%, 10% to 39% in 25%, and <10% in 7.7%. Stroke after recovery from acute TTP occurred in 0% (0 of 22) of patients with normal remission ADAMTS13 activity (>70%) and in 27.6% (8 of 29) of patients with low ADAMTS13 activity (≤70%; P = .007). In conclusion, stroke is common after recovery from TTP and is associated with reduced ADAMTS13 activity during remission.

RESUMEN

ABSTRACT: We report a patient with a high-titer factor VIII inhibitor refractory to immunosuppression. He initially presented with myocardial infarction requiring percutaneous coronary intervention (PCI) with bare metal stent placement. Despite Feiba prophylaxis, inadequate hemostasis prompted premature discontinuation of dual antiplatelet therapy (DAPT). Fifteen weeks later, the patient presented with a left anterior descending artery in-stent restenosis. This case report examines the Key Clinical Question of how to manage in-stent restenosis in a patient with acquired hemophilia A (AHA). After multidisciplinary discussions including hematology, cardiology, cardiac surgery, laboratory medicine, and pharmacy, emicizumab was initiated to facilitate PCI. Four weeks after emicizumab initiation, the patient underwent successful PCI with drug-eluting stent placement. Five months after discharge, he remains without signs or symptoms of cardiac disease or bleeding on DAPT and emicizumab. This case provides evidence of the potential of emicizumab for bleeding prophylaxis in AHA.

RESUMEN

PURPOSE OF REVIEW: A multitude of new drug and cell therapy approvals for lymphoma has prompted questions about the role of allogeneic blood or marrow transplantation (allo-BMT). We sought to review the latest evidence examining the role of allo-BMT for lymphoma in this evolving landscape. RECENT FINDINGS: Despite several new drug classes, there remains a large unmet need, particularly in hard to treat subtypes of lymphoma and for patients with relapsed/refractory disease. Allo-BMT can provide an opportunity for cure due to a potent graft vs lymphoma effect in high-risk relapse/refractory follicular lymphoma, mantle cell lymphoma, and aggressive T cell lymphomas. Chimeric antigen receptor T cell therapy and checkpoint blockers have improved outcomes for patients with relapsed /aggressive B cell lymphomas and Hodgkin lymphoma respectively; the role of allo-BMT consolidation in the treatment algorithm for responders to these therapies is an evolving topic. Expanded donor availability including haploidentical relatives has improved access to allo-BMT. Non-myeloablative conditioning regimens and post-transplant cyclophosphamide prophylaxis have improved early transplant-related morbidity and rates of graft versus host disease and translated into long-term survival for patients with lymphoid malignancies. Patient selection remains key, but allo-BMT remains the only modality able to deliver durable long-term remissions across different types of lymphoma.

RESUMEN

BACKGROUND: Immune checkpoint inhibitors (ICIs) may cause immune-related adverse events (irAEs). Methods to obtain real-time multidisciplinary input for irAEs that require subspecialist care are unknown. This study aimed to determine whether a virtual multidisciplinary immune-related toxicity (IR-tox) team of oncology and medicine subspecialists would be feasible to implement, be used by oncology providers, and identify patients for whom multidisciplinary input is sought. PATIENTS AND METHODS: Patients treated with ICIs and referred to the IR-tox team in August 2017 through March 2018 were identified. Feasibility was defined as receipt of electronic referrals and provision of recommendations within 24 hours of referral. Use was defined as the proportion of referring providers who used the team's recommendations, which was determined through a postpilot survey. Demographics and tumor, treatment, and referral data were collected. Patient features and irAE associations were analyzed. RESULTS: The IR-tox team was found to be feasible and used: 117 referrals from 102 patients were received in 8 months, all providers received recommendations within 24 hours, 100% of surveyed providers used the recommendations, and 74% changed patient management based on IR-tox team recommendations. Referrals were for suspected irAEs (n=106; 91%) and suitability to treat with ICIs (n=11; 10%). In referred patients, median age was 64 years, 54% were men, 13% had prior autoimmunity, and 46% received ICI combinations versus monotherapy (54%). The most commonly referred toxicities were pneumonitis (23%), arthritis (16%), and dermatitis (15%); 15% of patients had multisystem toxicities. Multiple referrals were more common in those treated with combination ICIs (odds ratio [OR], 6.0; P=.035) or with multisystem toxicities (OR, 8.1; P=.005). The IR-tox team provided a new multidisciplinary forum to assist providers in diagnosing and managing complex irAEs. This model identifies educational and service needs, and patients with irAEs for whom multidisciplinary care is most sought. CONCLUSIONS: A virtual multidisciplinary toxicity team for irAEs was a feasible and used service, and facilitated toxicity identification and management.
