COVAD survey 2 long-term outcomes: unmet need and protocol

Vaccine hesitancy is considered a major barrier to achieving herd immunity against COVID-19. While multiple alternative and synergistic approaches including heterologous vaccination, booster doses, and antiviral drugs have been developed, equitable vaccine uptake remains the foremost strategy to manage pandemic. Although none of the currently approved vaccines are live-attenuated, several reports of disease flares, waning protection, and acute-onset syndromes have emerged as short-term adverse events after vaccination. Hence, scientific literature falls short when discussing potential long-term effects in vulnerable cohorts. The COVAD-2 survey follows on from the baseline COVAD-1 survey with the aim to collect patient-reported data on the long-term safety and tolerability of COVID-19 vaccines in immune modulation. The e-survey has been extensively pilot-tested and validated with translations into multiple languages. Anticipated results will help improve vaccination efforts and reduce the imminent risks of COVID-19 infection, especially in understudied vulnerable groups

Lung cancer acting as a trigger of autoimmunity: a medical challenge

6 páginasThere is a complex, dynamic, and bidirectional connection between autoimmunity and cancer. The underlying mechanisms of carcinogenesis and physiopathological aspects of autoimmune diseases are not fully understood. However, there is a common immunological base related to expression of autoantigens by tumour cells that cause an anti-cancer immune response, thereby, triggering the development of paraneoplastic rheumatic syndromes and autoimmune rheumatic diseases in a genetically predisposed population. The case is reported of a 57 year-old man presenting with pulmonary renal syndrome, and who was diagnosed lung cancer and systemic lupus erythematosus at the same time.Existe una relación compleja, dinámica y bidireccional entre la autoinmunidad y el cáncer. Si bien los mecanismos carcinogénicos y fisiopatológicos de las enfermedades autoinmunes no están claramente dilucidados, existe una base inmunológica común relacionada con la expresión de autoantígenos por parte de las células tumorales que desencadenan una respuesta antitumoral, facilitando el desarrollo de síndromes paraneoplásicos reumáticos y enfermedades autoinmunes reumáticas en población genéticamente susceptible. Se presenta un caso de un hombre que debutó con un síndrome pulmón riñón y se diagnosticó cáncer de pulmón y lupus eritematoso sistémico de forma simultánea
