ABSTRACT

At the end of 2019, Wuhan, China, experienced an outbreak of a novel coronavirus. The SARS-CoV2 epidemiologic burden was constantly evolving, with numbers of infected persons, hospital admissions and deaths growing near exponentially. The pandemic outbreak of COVID-19 worldwide caught the health care systems in every country by storm and without a proper defense mechanism to cope and control such a pandemic, causing an overwhelming burden of illnesses that stressed the Health System capacity. In this context, telemedicine has been promoted and scaled up to reduce the risk of transmission. During the "lockdown", the AOU "Federico II" was forced to create peculiar pathways to ensure the safety of the patients and medical staff, and to keep an appropriate medical assistance, therefore it was introduced the telemedicine, wherever possible, by modifying the Information Technology (IT) related to the waiting times, rescheduling all booked visits and identifying several outpatient clinics suitable for telemedicine activities. In this paper the Authors reports their own experience with Telemedicine.

ABSTRACT

Background: Vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are highly effective. Nevertheless, immunocompromised participants were excluded from randomized controlled clinical trials. This study evaluates the efficacy and safety of the Pfizer/BioNTech BNT162b2 (BNT162b2) vaccine in patients with breast and gynecological cancer treated with active anticancer therapy versus a control cohort of healthy participants. Methods: Immune responses to the BNT162b2 vaccine in patients with breast cancer (n = 44) or a gynecological malignancy (n = 6) on active anticancer therapy (28 on chemotherapy, mostly anthracycline- or taxane-based, and 22 on target therapy) and in a control cohort of participants without cancer (n = 67) were investigated by SARS-CoV-2 neutralizing antibody titers measured by S1-binding immunoglobulin G (IgG) concentrations assessed using the LIAISON XL tools (DiaSorin S.p.A.). Response was assessed after a second dose of the BNT162b2 vaccine administered before and at least 3 weeks after the vaccine dose. Results: Overall, 43/50 (86%) patients of the cancer cohort (74% in the breast cancer group and 100% in the gynecological malignancy group) developed IgG antibodies after the second dose of the BNT162b2 vaccine. There were no statistically significant differences in responder rates between patients treated with chemotherapy and those on target therapy. The majority of patients who received chemotherapy with or without target therapy, 21/28 (75%), developed a reliable antibody titer after a vaccine. All seven non-responder patients were undergoing an anthracycline-based regimen. Based on IgG levels (0-400 AU/ml), patients were classified as negative ('non-responders'), weakly positive, or strongly positive ('responders'). No delay in cancer therapy schedule or reported side effects were recorded after BNT162b2 vaccine administration. All healthy participants were strongly positive. Responder rates differed significantly between the two study cohorts (p < 0.001). Conclusions: Most patients develop antibody titers after the second immunization. However, given the persistence of non-responders or weak responders, additional immunization booster seems to be required, along with proactive planning in the vaccination schedule, with vaccine administration spaced out over time with respect to chemotherapy.

ABSTRACT

INTRODUCTION: Since the pandemic of COVID-19 started from December 2019, remarkable numbers of infections and deaths associated with COVID-19 have been recorded worldwide. End-stage kidney disease patients on dialysis are particularly at high risk of infections due to impairments in the innate and adaptive immune systems. Vaccination on dialysis patients (DP) still remains challenging because of the variable response and a low seroconversion rate compared with healthy participants (HP). Therefore, it is urgently necessary to establish a different vaccination strategy for DP, in terms of the dose and administration time. METHODS: Here, we report an observational prospective cohort study in which the immunogenic efficacies of SARS-CoV-2 vaccine BNT162b2 on DP and HP were evaluated by absolute quantification of IgG levels in the blood. RESULTS: DP showed a delayed seroconversion after two vaccine doses, with a low absolute IgG levels compared to HP. While HP reached complete seroconversion within 10 days from the administration of a second dose, only 76% of DP were seropositive. After the booster dose, DP had a strongly improved seroconversion rate as well as antibody levels, reaching 97% seropositivity and 50 times enhancement on antibody levels. DISCUSSION/CONCLUSION: These results prompt to suggest an additional vaccine dose in DP, reducing the interval of time from the second dose. Since limited data are available on immune response in DP overtime after three vaccine doses currently, our study is among the first reports demonstrating the improved seropositivity and IgG levels in DP after the booster vaccine dose.

ABSTRACT

BACKGROUND: Immunosuppression induced by anticancer therapy in a COVID-19-positive asymptomatic patient with cancer may have a devastating effect and, eventually, be lethal. To identify asymptomatic cases among patients receiving active cancer treatment, the Federico II University Hospital in Naples performs rapid serological tests in addition to hospital standard clinical triage for COVID-19 infection. METHODS: From 6 to 17 April 2020, all candidates for chemotherapy, radiotherapy or target/immunotherapy, if negative at the standard clinical triage on the day scheduled for anticancer treatment, received a rapid serological test on peripheral blood for COVID-19 IgM and IgG detection. In case of COVID-19 IgM and/or IgG positivity, patients underwent a real-time PCR (RT-PCR) SARS-CoV-2 test to confirm infection, and active cancer treatment was delayed. RESULTS: Overall 466 patients, negative for COVID-19 symptoms, underwent serological testing in addition to standard clinical triage. The average age was 61 years (range 25-88 years). Most patients (190, 40.8%) had breast cancer, and chemotherapy with or without immunotherapy was administered in 323 (69.3%) patients. Overall 433 (92.9%) patients were IgG-negative and IgM-negative, and 33 (7.1%) were IgM-positive and/or IgG-positive. Among the latter patients, 18 (3.9%), 11 (2.4%) and 4 (0.9%) were IgM-negative/IgG-positive, IgM-positive/IgG-negative and IgM-positive/IgG-positive, respectively. All 33 patients with a positive serological test, tested negative for RT-PCR SARS-CoV-2 test. No patient in our cohort developed symptoms suggestive of active COVID-19 infection. CONCLUSION: Rapid serological testing at hospital admission failed to detect active asymptomatic COVID-19 infection. Moreover, it entailed additional economic and human resources, delayed therapy administrationand increased hospital accesses.

ABSTRACT

Background: At the end of 2019, Wuhan, China, experienced an outbreak of a novel coronavirus. The epidemiologic burden of COVID-19 is constantly evolving, with numbers of infected persons, hospital admissions and deaths growing near exponentially. The recent pandemic outbreak of COVID-19 worldwide caught the health care systems in every country around the world by storm and without a proper defense mechanism to cope and control such a pandemic. In fact, this outbreak is causing an overwhelming burden of illnesses that stresses health system capacity and adverse effects on healthcare workers including the risk of infection. In this context, telemedicine has been promoted and scaled up to reduce the risk of transmission. In this paper the Authors reports their own experience with Telemedicine. Methods: During the “lockdown”, the AOU“Federico II” was forced to create peculiar pathways to ensure the safety of the patients and medical staff, and to keep an appropriate medical assistance, therefore it was introduced the telemedicine, wherever possible, by modifying the Information Technology (IT) related to the waiting times, rescheduling all booked visits and identifying several outpatient’s clinics suitable for telemedicine activities. Besides, safe pathways were properly studied to screening all patients who had a medical consult in person.Results: Since the introduction of telemedicine service, 953 consultations were provided in this way, about 13 % of all medical consults delivered by AOU “Federico II” in this period; 97,38% of them were follow-up visits, that otherwise would have been missed during the current pandemic, so an economic loss has been avoided.  In addition, it has been calculated that, using Telemedicine visits vs a face-to-face consultation, about 65-70% of direct costs were spared by our Healthcare Company.Conclusions: Telemedicine has been the keystone that has allowed a rapid, appropriate response of whole overloaded healthcare systems to current Pandemic, and, as reported by Ohannessian et al., all stakeholders are encouraged to address the challenges and collaborate to promote the safe and evidence-based use of telemedicine during the current pandemic and future outbreaks, and the COVID-19 pandemic is a call to adopt the necessary regulatory changes supporting wide adoption of telemedicine.
