COVID-19 in multiple myeloma patients: frequencies and risk factors for hospitalization, ventilatory support, intensive care admission and mortality -cooperative registry from the Grupo Brasileiro de Mieloma Multiplo (GBRAM).

INTRODUCTION: This study evaluated outcomes and risk factors for COVID-19 in 91 Brazilian multiple myeloma (MM) patients between April 2020 and January 2022. RESULTS: Of the 91 MM patients diagnosed with COVID-19, 64% had comorbidities and 66% required hospitalization due to COVID-19, with 44% needing ventilatory support and 37% intensive care. Age (OR 2.02; 95%CI 1.02 - 7.7) and hypertension OR 4.5; 95%CI 1.3 - 15.5) were independently associated with hospitalization and certain MM therapies (corticosteroids and monoclonal drugs) were associated with ventilatory support (OR 4.3; 95%CI 1.3 - 14 and OR 5.7; 95%CI 1.8 - 18, respectively), while corticosteroids and immunomodulatory drugs were linked to ICU admission (OR 5.1; 95% CI 1.4 - 18 and OR 3.4; 95%CI 1.1 - 10, respectively). The overall mortality rate was 30%, with the highest rate observed in the ICU (73%). Additionally, the ECOG performance status was linked to increased mortality (OR 11.5; 95%CI 1.9 - 69). The MM treatment was delayed in 63% of patients who recovered from COVID-19. CONCLUSIONS: The findings highlight the need for preventing COVID-19 and prioritizing vaccination among MM patients, as they have high rates of severe outcomes in the event of COVID-19. It is also essential to monitor the potential clinical impacts of COVID-19 on MM patients in the long-term. Given the limited resources available in treating MM patients in Brazil during the COVID-19 pandemic, outcomes might be worse in this population.

Application of EBMT, MASCC, and qSOFA Scores to Predict Complicated Febrile Neutropenia and Mortality in Autologous Stem Cell Transplant Recipients.

BACKGROUND AND OBJECTIVES: Three different scores were addressed as predictors of outcomes in autologous stem cell transplant (Auto SCT): one was calculated by pretransplant characteristics (European Society for Blood and Marrow Transplantation [EBMT] risk score), and two were calculated at the onset of febrile neutropenia (Multinational Association for Supportive Care in Cancer [MASCC] and Quick Sequential Organ Failure Assessment [qSOFA]). We considered bloodstream infection (BSI), carbapenem prescription, admission to the intensive care unit (ICU), and mortality as outcomes. PATIENTS: A total of 309 patients with a median age of 54 years were enrolled. RESULTS: Patients with EBMT score ≥4 (EBMT 4+) had higher ICU rates (14% vs. 4%; p < 0.01) and more carbapenem prescriptions (61% vs. 38%; p < 0.001) than those with EBMT score <4. MASCC <21 points (MASCC HR) was associated with carbapenem prescription (59% vs. 44%; p = 0.013), ICU (19% vs. 3%; p < 0.01), and death (4% vs. 0; p = 0.014). Patients with at least two points by qSOFA (qSOFA 2+) had more frequent BSI (55% vs. 22%; p = 0.03), ICU admissions (73% vs. 7; p < 0.01), and death (18% vs. 0.7, p = 0.02). EBMT 4+ and MASCC HR achieved the best sensitivities for ICU. For death, the best sensitivity was obtained with MASCC. CONCLUSION: In conclusion, risk scores for Auto SCT showed an association with outcomes and had different performances when combined or used alone. Therefore, risk scores for Auto SCT are useful in supportive care and clinical surveillance in stem cell transplant recipients.

Metagenomic next-generation sequencing (mNGS) for diagnostically challenging infectious diseases in patients with acute leukemia.

This report shows the contribution of next-generation metagenomic sequencing (mNGS) as an alternative to challenging diagnostic infection in immunosuppressed individuals. Herein, we report three acute leukemia patients who developed severe invasive infections due to different etiologies: fungi, viruses, and protozoa. mNGS improved the diagnosis of the infections and provided the opportunity for adequate therapy. The mNGS is a hypothesis-free diagnostic platform, increasing potential in challenging diseases in hematological patients due to the extended diagnostic panel and the expedite access to the result.

COVID-19 in hematology: data from a hematologic and transplant unit

ABSTRACT During the COVID-19 pandemic, special attention has been addressed in cancer care to mitigate the impact on the patient's prognosis. We addressed our preparation to face COVID-19 pandemic in a Hematological and Stem Cell Transplant Unit in Brazil during the first two months of COVID-19 pandemic and described COVID-19 cases in patients and health care workers (HCW). Modifications in daily routines included a separation of area and professionals, SARS-CoV-2 screening protocols, and others. A total of 47 patients and 54 HCW were tested for COVID-19, by PCR-SARS-CoV-2. We report 11 cases of COVID-19 in hematological patients (including 2 post stem cell transplant) and 28 cases in HCW. Hematological cases were most severe or moderate and presented with several poor risk factors. Among HCW, COVID-19 were mostly mild, and all recovered without hospitalization. A cluster was observed among HCW. Despite a decrease in the number of procedures, the Transplant Program performed 8 autologous and 4 allogeneic SCT during the period, and 49 onco-hematological patients were admitted to continuing their treatments. Although we observed a high frequency of COVID-19 among patients and HCW, showing that SARS-CoV-2 is disseminated in Brazil, hematological patients were safely treated during pandemic times.

Managing patients with multiple myeloma during the COVID-19 pandemic: recommendations from an expert panel - ABHH monoclonal gammopathies committe

ABSTRACT Since the World has been facing the COVID-19 pandemic, special attention has been taken concerning cancer patients; related to their immunosuppression status, adding risk for more aggressive COVID-19 and mortality, but also concerns about the access and the quality of care in cancer therapy. The COVID-19 pandemic impacts the number of infected, its related mortality, as well as the care of cancer patients. Multiple myeloma patients are a particular group with several important aspects to be considered during pandemic times. In essence, they are immunosuppressed in different intensities during their treatment. Most of them are elderly and all of them require long-term therapy, with prolonged contact with the health care system, possibly including a stem cell transplant during the treatment. A panel of experts in multiple myeloma and infectious diseases discusses pieces of evidence and the lack of the same in the scenario of COVID-19 in myeloma patients, while also exposing what is expected for the next phases of the COVID-19 pandemic.

Daunorubicin 90 mg/m2 in Acute Myeloid Leukemia Induction: Increased Toxicity in Young Patients.

BACKGROUND: The combination of an anthracycline and cytosine arabinoside has been the standard induction therapy for acute myeloid leukemia for more than 3 decades. The clinical benefit of intensification of the daunorubicin dose to 90 mg/m2 has been supported by randomized trials. Based on these promising results, in 2010 we changed our induction protocol of acute myeloid leukemia, increasing the dose of daunorubicin. PATIENTS AND METHODS: We retrospectively analyzed the treatment outcome of patients treated with high-dose daunorubicin (90 mg/m2 on days 1-3) and cytosine arabinoside (200 mg/m2/day continuous infusion on days 1-7) compared with patients receiving 45 to 60 mg/m2 of daunorubicin. Twenty-six previously untreated patients younger than 60 years of age were included. Twelve received high-dose daunorubicin (HD) and 14 the low-dose (LD). Seventeen patients were in complete remission after 1 induction cycle. RESULTS: There was no overall difference in complete remission rate between HD and LD (66% vs. 64%; P = 1.0). Thirty-day induction mortality was 15.3% overall, with a nonsignificant difference between groups (25% vs. 7.1%; P = .3). Relapses were observed in 9 (53%) patients: 3 (37.5%) in the HD group and in 6 (66.6%) in the LD group (P = .34). Invasive fungal disease (41.6% vs. 0%; P = .012), creatinine elevation (P = .001), abdominal pain (33% vs. 0%; P = .033), and need for intensive care unit admission (33.3% vs. 0%; P = .033) were more frequent in the HD group. Four patients in the HD group developed neutropenic enterocolitis (P = .033). CONCLUSION: These data indicate that 90 mg/m2 of daunorubicin increased the toxicity compared with lower doses.

Diagnostic-driven antifungal therapy in neutropenic patients using the D-index and serial serum galactomannan testing

Abstract Introduction Invasive mold disease is an important complication of patients with hematologic malignancies, and is associated with high mortality. A diagnostic-driven approach has been an alternative to the classical empiric antifungal therapy. In the present study we tested an algorithm that incorporated risk stratification using the D-index, serial serum galactomannan and computed tomographic-scan to guide the decision to start antifungal therapy in neutropenic patients. Patients and methods Between May 2010 and August 2012, patients with acute leukemia in induction remission were prospectively monitored from day 1 of chemotherapy until discharge or death with the D-index and galactomannan. Patients were stratified in low, intermediate and high risk according to the D-index and an extensive workup for invasive mold disease was performed in case of positive galactomannan (≥0.5), persistent fever, or the appearance of clinical manifestations suggestive of invasive mold disease. Results Among 29 patients, 6 (21%), 11 (38%), and 12 (41%) were classified as high, intermediate, and low risk, respectively. Workup for invasive mold disease was undertaken in 67%, 73% and 58% (p = 0.77) of patients in each risk category, respectively, and antifungal therapy was given to 67%, 54.5%, and 17% (p = 0.07). Proven or probable invasive mold disease was diagnosed in 67%, 45.5%, and in none (p = 0.007) of high, intermediate, and low risk patients, respectively. All patients survived. Conclusion A risk stratification using D-index was a useful instrument to be incorporated in invasive mold disease diagnostic approach, resulting in a more comprehensive antifungal treatment strategy, and to guide an earlier start of treatment in afebrile patients under very high risk.

Invasive fungal diseases in patients with acute lymphoid leukemia.

Invasive fungal disease (IFD) represents an important complication in patients with acute lymphoid leukemia (ALL). The objectives of this study were to determine the prevalence of IFD in ALL patients with neutropenia, identify factors associated with IFD, and estimate the impact of IFD on the outcome. All patients with ALL who developed febrile neutropenia from 1987 to 2013 were evaluated. Cases of IFD were classified as proven or probable. Factors associated with IFD were evaluated by comparing episodes with and without a diagnosis of IFD. Among 350 episodes of febrile neutropenia, 31 IFDs were diagnosed (8.8%). Prolonged neutropenia was the only factor associated with IFD caused by yeasts. Factors associated with IFD caused by molds by multivariate analysis were the period after 2008, receipt of allogeneic transplant, relapsed ALL and prolonged neutropenia. Patients in relapse should receive induction chemotherapy in rooms with HEPA filter and receive antifungal prophylaxis.

Feasibility and outcome of the hyper-CVAD regimen in patients with adult acute lymphoblastic leukemia.

BACKGROUND: Current chemotherapy regimens for adults with acute lymphoblastic leukemia (ALL) result in high rates of complete remission (CR), but relapses are still frequent. PATIENTS AND METHODS: In this retrospective single-center study, we evaluated the results of the Hyper-CVAD (fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone) regimen in 49 ALL patients treated between 2001 and 2013. No exclusion criteria were applied. The primary outcome measure was the CR rate. RESULTS: Forty-six of the 49 patients (93.8%) obtained CR, and 3 (6%) patients died during induction. Philadelphia chromosome was present in 6 patients (12.2%); in all a CR was obtained. Among the 46 patients in CR, 30 (65.2%) received the full planned intensive-phase treatment (8 cycles). Allogeneic hematopoietic cell transplantation was performed in 2 (4%) patients in first CR and in 3 (6%) patients after a second CR. Nonrelapse mortality was observed in 8 patients (16.3%). The median overall survival (OS) and 5-year OS were 24.4 months and 35%, respectively. Initial leukocyte count (> 30 × 10(9)/L) was an important prognostic factor. CONCLUSION: Hyper-CVAD as an induction regimen for adults and adolescents with ALL was feasible and yielded a high rate of CR. Relapse rates and OS were comparable to other series but still unsatisfactory.

Risk factors for invasive fusariosis in patients with acute myeloid leukemia and in hematopoietic cell transplant recipients.

BACKGROUND: Risk factors for invasive fusariosis (IF) have not been characterized. We attempted to identify risk factors for IF in a prospective cohort of hematologic patients treated in 8 centers in Brazil. METHODS: Patients with (cases) and without (controls) proven or probable IF diagnosed in a cohort of patients with acute myeloid leukemia (AML) or myelodysplasia (MDS), and in allogeneic hematopoietic cell transplant (HCT) recipients (early, until day 40; late, after day 40 posttransplant) were compared by univariate Cox regression analysis. RESULTS: Among 237 induction remission courses of AML/MDS and 663 HCTs (345 allogeneic and 318 autologous), 25 cases of IF were diagnosed. In the AML/MDS cohort, active smoking (hazard ratio [HR], 9.11 [95% confidence interval {CI}, 2.04-40.71]) was associated with IF. Variables associated with IF in the early phase of allogeneic HCT were receipt of antithymocyte globulin (HR, 22.77 [95% CI, 4.85-101.34]), hyperglycemia (HR, 5.17 [95% CI, 1.40-19.11]), center 7 (HR, 5.15 [95% CI, 1.66-15.97]), and AML (HR, 4.38 [95% CI, 1.39-13.81]), and in the late phase were nonmyeloablative conditioning regimen (HR, 35.08 [95% CI, 3.90-315.27]), grade III/IV graft-vs-host disease (HR, 16.50 [95% CI, 2.67-102.28]), and previous invasive mold disease (HR, 10.65 [95% CI, 1.19-95.39]). CONCLUSIONS: Attempts to reduce the risk of IF may include smoking cessation, aggressive control of hyperglycemia, and the use of a mold-active agent as prophylaxis in patients receiving nonmyeloablative HCT or ATG in the conditioning regimen. Future research should further explore smoking and other prehospital variables as risks for IF.

Randomized double-blind clinical trial comparing clobetasol and dexamethasone for the topical treatment of symptomatic oral chronic graft-versus-host disease.

Patients who undergo allogeneic stem cell transplantation frequently develop an immunologic disease caused by the reactivation of the graft to the host tissues. This disease is called graft-versus-host disease (GVHD) and it is usually a systemic disorder. In a large proportion of cases, oral disorders that are related to a chronic phase of GVHD (cGVHD) occur, and their treatment involves the use of topical immunosuppressive drugs. Several medications have been studied for this purpose, but only a small number of clinical trials have been published. The present study is a randomized, double-blind clinical trial that compares topical clobetasol and dexamethasone for the treatment of symptomatic oral cGVHD. Patients were randomly assigned to treatment with clobetasol propionate .05% or dexamethasone .1 mg/mL for 28 days. In both arms, nystatin 100,000 IU/mL was administered with the corticosteroid. Oral lesions were evaluated by the modified oral mucositis rating scale (mOMRS) and symptoms were registered using a visual analogue scale. Thirty-five patients were recruited, and 32 patients were randomized into the study groups: 18 patients (56.3%) to the dexamethasone group and 14 patients (43.8%) to the clobetasol group. The use of clobetasol resulted in a significant reduction in mOMRS total score (P = .04) and in the score for ulcers (P = .03). In both groups, there was significant symptomatic improvement but the response was significantly greater in the clobetasol group (P = .02). In conclusion, clobetasol was significantly more effective than dexamethasone for the amelioration of symptoms and clinical aspects of oral lesions in cGVHD.
