ABSTRACT
Background: During the initial surge of the COVID-19 pandemic in the spring and summer of 2020, pediatric heart centers were forced to rapidly alter the way patient care was provided in order to minimize interruption to patient care as well as exposure to the virus. In this study, we used a survey-based approach to characterize the changes that occurred in pediatric cardiology practices across the country during and just following the initial peak of COVID-19. Methods: In this survey based descriptive study we characterize changes that occurred within pediatric cardiology practices across the United States and describe provider experience and attitudes towards these changes during the pandemic. decision making during this period. This survey was emailed to an existing list serve of American Academy of Pediatrics Section on Cardiology and Cardiothoracic Surgery (AAP:SOCCS) members. Recipients of the survey included pediatric cardiologists, cardiothoracic surgeons, and fellows-intraining. The questionnaire was initially distributed in June 2020 and was active through August 2020. Results: Surveys were returned by 79 participants across 28 states. Areas of practice of respondents included general cardiology, non-invasive imaging, electrophysiology, heart failure/transplant, interventional cardiology, and adults with congenital heart disease. Common changes that were implemented included decreased numbers of procedures, limiting visitors, and shifting towards telemedicine encounters. There was a high level of satisfaction among providers with telemedicine encounters and a variety of platforms were utilized. Echocardiography was less likely to be performed during the pandemic as compared to prior to the pandemic in nearly all clinical scenarios presented. More than half of respondents expressed concerns about financial stability with regards to personal or practice situation but most were not frequently concerned about their personal safety. Conclusion: Pediatric cardiology practice across the country was heavily impacted by COVID-19 and required many adaptations including minimization of non-essential procedures and increasing use of telemedicine. Providers were generally satisfied with telemedicine and utilized several platforms. Financial concerns were common;however, most participants were not frequently concerned about personal safety. Inter-institutional collaboration could be useful in creating standardized protocols based on shared experiences that could be rapidly implemented in future public health crises. Experience with Telemedicine. A) Barriers to implementing telemedicine. B) Provider rated effectiveness of telemedicine. C) Home monitoring devices used as part of telemedicine program. D) Provider satisfaction vs perceived patient satisfaction with telemedicine encounters. Likelihood of Performing Echocardiography Prior to and During COVID-19 Pandemic. Participants were asked to rate the likelihood for each scenario as always, frequently, occasionally, or never. Responses were converted to a 5-point scale. Pre- and post- responses were analyzed using Wilcoxon signed-rank test. Significant decreases in likelihood of echocardiography were found in nearly all situations.
ABSTRACT
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for an ongoing global pandemic. Phase III trials have demonstrated excellent efficacies of mRNA vaccines against SARS-CoV-2 in large population studies (Baden LR, NEJM, 2021;Polack FP, NEJM, 2020). Immunosuppressed individuals such as chronic lymphocytic leukemia (CLL) patients are at risk for a suboptimal response to 2 vaccine doses (Herishanu Y, Blood, 2021). The French National Authority for Health recommends the use of a third dose in immunosuppressed patients. However, seroconversion rate after the triple-dose vaccine is not yet known. The objective of our study was to evaluate SARS-CoV-2 antibody responses after the first, second and third doses of the BNT162b2 and mRNA-1273 vaccines. Data were collected from 17 French Innovative Leukemia Organization (FILO) investigating centers and the French CLL patients' association (SILLC). SARS-CoV-2 IgG anti-Spike levels were measured at 4-6 weeks after each vaccine dose. A total of 530 patients and 14 controls were included in the study. Vaccine response was evaluated post-dose 1 for 158 CLL patients, post-dose 2, for 506 patients and post-dose 3 for 66 patients. Peripheral blood lymphocyte subsets were studied post-dose 2 by flow cytometry in 80 CLL patients and 14 controls. The median age of the patients was 71 years (range 37-93), 218 (40%) were treatment-naïve (TN), 136 (26%) had a prior CLL treatment and 176 (34%) were on therapy. Post-dose 1, the global response rate was 27% (43/158). TN patients had a response rate of 34% (23/67), similar to those who had a prior CLL treatment (33%,12/36), and higher compared to on-therapy patients (15%, 8/55, P=0.02). Post-dose 2, the global response rate was 52% (265/506). TN patients had the highest response rate of 72% (151/210) compared to previously treated patients, mostly by immunochemotherapy (60%, 78/130, P=0.02) and on-therapy patients (22%, 36/166, P<0.001) (Figure 1A). Among the 166 on-therapy patients, mostly receiving targeted agents, those receiving venetoclax monotherapy achieved a significantly higher response rate (52%, 12/23) than those treated with BTK inhibitors (BTKi) ibrutinib or acalabrutinib (22%, 23/104, P<0.001). Patients treated with venetoclax+anti-CD20 monoclonal antibodies (n=19) or venetoclax+BTKi (n=6) were all seronegative after the second dose of vaccine (Figure 1B). In multivariate analysis, the variables found to be significantly associated with seroconversion were age >65 years (OR 0.55, 95% CI 0.33-0.92, P=0.02), ongoing CLL treatment (OR 0.13, 95% CI 0.07-0.23, P<0.001) and gamma-globulins ≤6g/L (OR 0.41, 95% CI 0.19-0.88, P=0.03). Flow cytometry results suggest a differential balance of the T CD4+ cell subpopulations in Binet stage A and in patients on targeted therapy compared to healthy controls. Post-dose 2 seronegative patients were proposed a third dose and to date, 66 have been tested for the antibody response 4-6 weeks post-dose 3. The post-dose 3 response rate was 42% (28/66). TN patients and previously treated patients had a significantly higher response rate (57%, 16/28) compared to on-therapy patients (32%, 12/38, P=0.03). We further analyzed patients tested post-dose 2 with the Abbott Architect SARS-CoV-2 IgG anti-Spike assay (n=24). Those who achieved seroconversion after the third dose (n=10) had significantly higher titers post-dose 2 (median 12, IQR 3.0-40.8) compared to those who remained seronegative (n=14) (median 2.2, IQR 0.5-5.1, p<0.01), although both median values are considered below the threshold by the manufacturer. An additional cohort of 40 CLL patients who presented a SARS-CoV-2 infection prior to vaccination participated to the study and was analyzed independently. All patients achieved seroconversion after infection and a single dose of vaccine, even though 30% (n=12) had an ongoing CLL treatment. In conclusion, double-dose mRNA vaccination generated a humoral response in 52% of our CLL cohort and a third dose induced seroconversion in 42% of the patients who remained seronegat ve after the second dose. The major independent predictor of negative antibody response was ongoing treatment with BTKi. The strongest boost to immune response against the virus seems to be SARS CoV-2 infection, as a substantial increase in anti-Spike antibodies was observed in all CLL patients with prior infection, after a single dose vaccination.
ABSTRACT
Chronic lymphocytic leukemia (CLL) patients experience both humoral and cellular immune deficiency, with a reduced number of normal B lymphocytes, and hypogammaglobulinemia. Previous large studies on vaccination efficacy are scarce but it is well-established that CLL patients have a poorer response than normal subjects to vaccination and are at increased risk of infection. Efficacy of anti-SARS-Cov-2 vaccination in CLL has been recently published by the Israeli group (Herishanu, 2021) showing that among hematological malignancies, patients who presented CLL disease are the least responsive to vaccination. We have collected the results of a large cohort of 502 French patients after vaccination by either BNT162b2 or mRNA-1273 mRNA vaccine. Patients received 2 doses at a 4-week interval. For those who received the 3rd dose, the interval was usually longer (between 6 and 8 weeks after 2nd dose). The median time to sample collection for serology was 4 weeks, and IgG anti-SARS-CoV-2 Spike antibody levels were measured by commercially available tests. We evaluated patients after the 1st and 2nd doses and collected matched samples whenever possible. Patients who had a previous COVID-19 infection were analyzed separately. We evaluated 176 patients after the 1st dose and the global seroconversion rate was only 31% (55/176). We evaluated 455 patients after the 2nd dose, and the global rate of seroconversion was 54% (246/455). Matched samples after both first and second doses were available for 118 patients. In this cohort, among the 87 patients who were seronegative after the first dose, 42 patients (48%) became positive after the second dose. Most patients who remained seronegative after two doses, received the third dose. The administration of the third dose program started recently, therefore, to date, we have the results for 31 patients only. Among these patients, 18 remained negative after this 3rd dose, while 13 (42%) seroconverted. Therefore, if we extrapolate these data, it is expected that approximately only 70-75% of CLL patients will be protected by vaccination (either by two or three doses) at the end of the vaccination program. On the other hand, 40 patients who received at least one dose of vaccine had presented a COVID-19 infection before vaccination. In this group of patients, the humoral response was evaluated in 29 patients. All of them except one, presented very high anti-Spike antibodies titer, even after one dose, and the only patient who remained seronegative after vaccination was on prolonged anti-CD20 therapy for autoimmune thrombocytopenia. We also collected cases of COVID-19 infection post-vaccination. Nineteen patients presented a COVID-19 infection after vaccination, 11/19 presented the infection after the first dose, and 8/19 after the second dose. Among those eight patients, five presented the first symptoms within the first 2 weeks after the second dose and had a more severe COVID-19 infection while the three patients with a later onset of symptoms (4-6 weeks after vaccination) had very mild symptoms. All patients tested had no antibody response before COVID infection but had highly positive anti-Spike titers after infection. Currently, the COVID- 19 pandemic has settled down and it is difficult to know if the absence of post-vaccination COVID-19 infection is related to the slowing of the pandemic or if CLL patients are protected by cell-mediated immunity, even in the absence of antibody response. In conclusion, double-dose mRNA vaccination generated a humoral response in 54% of our CLL cohort, and a third dose induced seroconversion in 40% of the patients who were seronegative after the second dose. However, the strongest boost to the immune response against the virus seems to be the COVID-19 infection, as a substantial increase in anti-Spike antibodies was observed in all CLL patients after infection, even if they were negative post-vaccination.
ABSTRACT
With the emergence of targeted therapies, defining the best strategy for the treatment of previously untreated CLL patients remains challenging. The aim of this phase 2 study was to compare the efficacy of an association with ibrutinib and venetoclax (IV) to the standard FCR regimen in fit patients with intermediate-risk CLL defined by either unmutated IGHV status, 11q deletion, or complex karyotype in the absence of TP53 abnormality. Patients were randomized 1:1 between two treatment arms, i.e. FCR 6 cycles or IV. After a lead-in phase of ibrutinib as a single agent from the month (M)1 to M3, the total duration of treatment with IV was based on the response achieved at M9;if bone marrow (BM) MRD was <0.01% using flow cytometry, the treatment was continued for 6 additional months until M15 and then stopped;if BM MRD at M9 was ≥0.01%, the treatment with IV was continued for 18 additional months until M27. The primary endpoint was the percentage of patients with BM MRD <0.01% at M27 in both arms. We present here the preliminary results on the first evaluation done at M9 including CT-scan, BM biopsy, and MRD assessment in PB and BM after the inclusion of all the 120 patients as initially planned. One hundred and twenty patients were enrolled from September 2019 to February 2021. The median age was 59 [34-72] and 61 [34-74] years in the FCR and IV arms, respectively. The characteristics of the patients were well-balanced between the 2 arms in terms of gender (male 72% FCR, 74% IV), PS ECOG 0-1 (59% FCR, 68% IV), and Binet stage (A, B, and C 15, 64, 21% for FCR;8.5, 59, and 32% for IV). No major difference in terms of cytogenetic features was noted, all patients but one had unmutated IGHV. At the time of data cut-off for this interim analysis, the median follow-up for all cohort was 12.7 [4.5.9-21.4] months. The frequency of patients presenting all grades adverse events (AE) so far was 90% (grade ≥3: 45%) in the FCR arm and 80% (grade ≥3: 45%) in the IV arm. The rate of infusion-related reactions (IRR) in the FCR arm was 35% on cycle 1-day 1 (14% grade 3-4);for the IV arm, 5% of patients experienced tumor lysis syndrome (TLS) (grade 3 for 1 patient). Ibrutinib doses were reduced for seven patients (four permanently stopped and three resumed at a lower dose because of toxicities (digestive, hepatic, or hematological). Venetoclax was permanently discontinued before M9 in four patients (digestive toxicities and grade 4 neutropenia). Fifty-two serious adverse events were reported of which 22 were in the IV arm (among them one sudden death, one ischemic stroke, one acute coronary syndrome, two atrial fibrillations, two TLS, two acute renal failures, one hepatitis, one neutropenia, two COVID pneumonitis, and one osteoporotic fracture) and 30 in the FCR arm (among them five febrile neutropenia, one hemolytic anemia, one thrombocytopenia, three IRR, three TLS, three COVID pneumonitis, one acute myeloid leukemia, one myelodysplasic syndrome). All patients with COVID pneumonitis had a favorable evolution with the need for intensive care and convalescent plasma for three of them. The first 85 patients included in the study have reached M9 and among them, nine prematurely discontinued the study, (one active hemolysis, one ischemic stroke, one TLS, one hepatitis, and one sudden death in the IV arm;three hematologic toxicities and one early progression in the FCR arm). In the evaluated patients (n=74), 69% of patients in the FCR arm and 43% of patients in the IV arm achieved bone BM MRD <0.01%. The complete (CR, CRi) and partial response rates were 56 and 44% in the FCR arm and 74 and 26% in the IV arm, respectively. In conclusion, preliminary results show a lower BM MRD rate in the IV arm compared to the FCR arm at M9, with toxicity that remains significant and relatively similar between the two arms. However, BM MRD rate may improve after longer exposure to the IV combination and the analysis of the primary endpoint at M27 will be decisive in determining the best therapeutic strategy.
ABSTRACT
Background. Safety net HIV providers face operational challenges during the COVID pandemic with services often transformed to telehealth. HIV infected persons are a priority population for SARS CoV-2 vaccination. Medical mistrust of COVID vaccines has been cited as a contributor to vaccine hesitancy. Data on efficient and successful vaccination efforts of HIV infected persons in safety net health systems is needed. In San Mateo County, Latino persons comprised 42% of all COVID cases, Whites 16%, and African Americans 2%. Methods. SARS CoV2 vaccination with BNT162b2 (Pfizer-BioNTech), mRNA-1273 (Moderna) or Ad26.COV2.S (Janssen) vaccine were offered beginning February 2, 2021 through May 28, 2021 in a northern California public County HIV clinic. Clinic patients were contacted by bilingual English/Spanish speaking HIV clinic staff and appointments scheduled at County affiliated vaccination sites. Clinic staff followed up by phone with patients who did not initially accept vaccine. We calculate the percentage of patients who completed vaccine series and use multivariable logistic regression analysis to estimate the odds of series completion by patient race/ethnicity, gender and age. Results. Virtually all, 95% (349/365) of HIV patients in our County HIV clinic were offered vaccine during a 17 week period. Among those, 86% (313/365) accepted and received at least one dose and 80% completed the series (292/365) at time of this analysis. Janssen vaccine was given to only 2% (7/313) patients. Series completion was highest among Latinos and Asians. Latinos had the highest odds of vaccine series completion (OR = 4.12;95% CI 1.71 - 9.93). COVID-19 Vaccine Series Completion in a California Public HIV Clinic by Race/ Ethnicity, Age and Sexual Orientation, n=364 Conclusion. HIV patients offered SARS CoV2 vaccine by County HIV clinic staff with established patient care relationships had high vaccine acceptance (80%), comparable to 68% series completion in the county overall and 56% in the health equity quartile county census tracts. Latino HIV infected persons were most likely to complete the COVID vaccine series. Ryan White funded HIV clinics are ideal hubs to coordinate HIV patient COVID vaccination efforts. Adding COVID vaccine completion to HIV clinic performance measures would likely be beneficial.

ABSTRACT
Introduction Au cours des pneumopathies à SARS-CoV-2, plusieurs stratégies thérapeutiques ont été proposées La description d’une aggravation secondaire liée à un orage cytokinique a justifié l’utilisation de molécules anti-inflammatoires Du fait de la disponibilité, du faible coût, de son utilisation dans d’autres pathologies infectieuses, les corticoïdes ont été proposés pour la prise en charge des patients à ce stade de l’infection Nous avons analysé l’ensemble des données d’une cohorte de patients hospitalisés pour une infection grave à SARS-CoV-2 L’objectif principal était d’étudier l’effet des corticoïdes sur l’incidence de ces évènements graves : intubation orotrachéale (IOT) ou décès (DC) Matériels et méthodes Les données ont été recueillies de manière rétrospective chez les patients hospitalisés pour une infection grave documentée par PCR (81 %) ou scanner thoracique (93 %) entre le 15/03/2020 et le 15/04/2020 Nous avons inclus les patients avec un score OMS=5 et nécessitant un débit d’O2 supérieur à 3 L/min pour maintenir une saturation>94 % Les patients décédés ou transférés en réanimation dans les 48heures suivant l’admission ont été exclus, ainsi que ceux inclus dans des protocoles thérapeutiques La corticothérapie était administrée, après discussion pluridisciplinaire, à la posologie de 2mg/kg équivalent prednisone de j1 à j3 puis 1mg/kg les 3jours suivants Les malades traités par corticoïdes (groupe CT) ont été comparés aux malades de même niveau de gravité pris en charge avant la mise en place de la RCP le 2 avril, et traités selon le même standard de soin (groupe sans CT) Le critère d’évaluation principal était la survenue d’une IOT ou le DC Résultats Un total de 120 patients a été analysé : 39 dans le groupe CT, 81 dans le groupe sans CT Les 2 groupes avaient la même moyenne d’âge (66,4±14 ans groupe CT, 66,1±15 ans groupe sans CT ;p=−0,9), même sexe ratio (p=0,4), même niveau d’atteinte sur le TDM, même paramètres d’inflammation à l’entrée (CRP 135±86mg/L groupe CT et 118±90mg/L groupe sans CT) Le nombre de patient en limitation de soin était le même dans chaque groupe, n=14 (35 %) groupe CT, n=27 (33 %) groupe sans CT (p=0,9) Le nombre de malades IOT ou DC était significativement différent dans le groupe CT n=9 (23 %), comparativement au groupe sans CT n=42 (53 %) avec p<0,01 Cette différence était plus importante chez les patients sans limitation de soins : groupe CT aucun IOT ou DC, groupe sans CT n=20 (37 %) La différence d’incidence d’IOT ou DC n’était pas significative dans le sous-groupe des patients limités, groupe CT n=9 (64 %) et groupe sans CT n=22 (81 %) IOT/DC (p=0,27) Conclusion Même si le nombre limité de patients, le caractère rétrospectif et monocentrique de l’étude ne permettent pas d’extrapoler les données, nous confirmons l’intérêt de la corticothérapie pour la prise en charge des patients atteints de pneumopathie à SARS-CoV-2 aigu, à la phase inflammatoire Les bénéfices à long terme restent à être évalués
