Psychiatric Admissions in a Large Hospital in Madrid during COVID-19 Lockdown: Was There a Change in Patient Profile?

COVID-19 led to a reorganization of health care in Madrid. The objective of this study is to describe the sociodemographic and clinical profile of psychiatric patients admitted to Gregorio Marañón Hospital during lockdown.

Impact of chemotherapy and/or immunotherapy on neutralizing antibody response to SARS-CoV-2 mRNA-1237 vaccine in patients with solid tumors.

Patients with solid tumors have been a risk group since the beginning of the SARS-CoV-2 pandemic due to more significant complications, hospitalizations or deaths. The immunosuppressive state of cancer treatments or the tumor itself could influence the development of post-vaccination antibodies. This study prospectively analyzed 89 patients under chemotherapy and/or immunotherapy, who received two doses of the mRNA-1237 vaccine, and were compared with a group of 26 non-cancer individuals. Information on adverse events and neutralizing antibodies against the ancestral strain of SARS-CoV-2 (WH1) have been analyzed. Local reactions accounted for 65%, while systemic reactions accounted for 46% of oncologic individuals/cancer patients. Regarding the response to vaccination, 6.7% of cancer patients developed low neutralizing antibody levels. Lower levels of neutralizing antibodies between cancer and non-cancer groups were significant in individuals without previous SARS-CoV-2 infection, but not in previously infected individuals. We also observed that patients receiving chemotherapy or chemoimmunotherapy have significantly lower levels of neutralizing antibodies than non-cancer individuals. In conclusion, our study confirms the importance of prioritizing cancer patients receiving anticancer treatment in SARS-CoV-2 vaccination programs.

Immune Response and Effects of COVID-19 Vaccination in Patients with Lung Cancer-COVID Lung Vaccine Study.

Lung cancer patients represent a subgroup of special vulnerability in whom the SARS-CoV-2 infection could attain higher rates of morbidity and mortality. Therefore, those patients were recommended to receive SARS-CoV-2 vaccines once they were approved. However, little was known at that time regarding the degree of immunity developed after vaccination or vaccine-related adverse events, and more uncertainty involved the real need for a third dose. We sought to evaluate the immune response developed after vaccination, as well as the safety and efficacy of SARS-CoV-2 vaccines in a cohort of patients with lung cancer. Patients were identified through the Oncology/Hematology Outpatient Vaccination Program. Anti-Spike IgG was measured before any vaccine and at 3-6-, 6-9- and 12-15-month time points after the 2nd dose. Detailed clinical data were also collected. In total, 126 patients with lung cancer participated and received at least one dose of the SARS-CoV-2 vaccine. At 3-6 months after 2nd dose, 99.1% of baseline seronegative patients seroconverted and anti-Spike IgG titers went from a median value of 9.45 to 720 UI/mL. At the 6-9-month time point, titers raised to a median value of 924 UI/mL, and at 12-15 months, after the boost dose, they reached a median value of 3064 UI/mL. Adverse events to the vaccine were mild, and no SARS- CoV-2 infection-related deaths were recorded. In this lung cancer cohort, COVID-19 vaccines were safe and effective irrespective of the systemic anticancer therapy. Most of the patients developed anti-Spike IgG after the second dose, and these titers were maintained over time with low infection and reinfection rates with a mild clinical course.

Immune-checkpoint inhibitors for lung cancer patients amid the COVID-19 pandemic: a case report of severe meningoencephalitis after switching to an extended-interval higher flat-dose nivolumab regimen.

Alternative dosage regimens for some anticancer therapies have been proposed in the midst of the SARS-COV-2 pandemic in order to protect the patients from attending to health care facilities. Flat-dosing of several immune-checkpoint inhibitors (ICIs), including nivolumab, have been established. Although generally well tolerated with no new safety signals, new dosages can associate novel individual toxicities. As the use of ICIs is increasing in cancer patients, the present case report is a reminder for clinicians of potential novel toxicities, as well as the need for an interdisciplinary approach for their recognition and treatment. We report the occurrence of a severe neurologic toxicity in a patient with non-small cell lung cancer (NSCLC) who developed should be changed to which occurred after two doses of extended higher interval flat-dose nivolumab despite two years of clinical stability on prior nivolumab regimen. Patient developed fever, language impairment and altered mental status. The work-up tests excluded other potential causes and the most likely diagnosis was meningoencephalitis. Fortunately, with medical treatment, which consisted of high dose steroids, the patient recovered to his baseline situation and symptoms did not recurred, even though nivolumab was resumed. Alternate ICI regimens may have unique immune-related adverse event profiles.
