Significance There is growing evidence that preexisting autoantibodies neutralizing type I interferons (IFNs) are strong determinants of life-threatening COVID-19 pneumonia. It is important to estimate their quantitative impact on COVID-19 mortality upon SARS-CoV-2 infection, by age and sex, as both the prevalence of these autoantibodies and the risk of COVID-19 death increase with age and are higher in men. Using an unvaccinated sample of 1,261 deceased patients and 34,159 individuals from the general population, we found that autoantibodies against type I IFNs strongly increased the SARS-CoV-2 infection fatality rate at all ages, in both men and women. Autoantibodies against type I IFNs are strong and common predictors of life-threatening COVID-19. Testing for these autoantibodies should be considered in the general population.

Rev Alerg Mex. 2017;64 Supl 1:s11-s128. AbstractBackground: The need for a national guideline, with a broad basis among specialists and primary care physicians was felt in Mexico, to try unifying asthma management. As several high-quality asthma guidelines exist worldwide, it was decided to select the best three for transculturation. Methods: Following the internationally recommended methodology for guideline transculturation, ADAPTE, a literature search for asthma guidelines, published 1-1-2007 through 31-12-2015 was conducted. AGREE-II evaluations yielded 3/40 most suitable for transculturation. Their compound evidence was fused with local reality, patient preference, cost and safety considerations to draft the guideline document. Subsequently, this was adjusted by physicians from 12 national medical societies in several rounds of a Delphi process and 3 face-to-face meetings to reach the final version. Results: Evidence was fused from British Thoracic Society Asthma Guideline 2014, Global Initiative on Asthma 2015, and Guía Española del Manejo del Asma 2015 (2016 updates included). After 3 Delphi-rounds we developed an evidence-based document taking into account patient characteristics, including age, treatment costs and safety and best locally available medication. Conclusion: In cooperation pulmonologists, allergists, ENT physicians, paediatricians and GPs were able to develop an evidence-based document for the prevention, diagnosis and treatment of asthma and its exacerbations in Mexico.Keywords: Clinical practice guideline; Asthma; Asthmatic exacerbation; Bronchodilator; Inhaled corticosteroid; Spirometry; Immunotherapy. IntroducciónLa presentación de este documento muestra la importancia del asma en México por su alta prevalencia, pero también por su subdiagnóstico y tratamiento deficiente, que propician un mal control de los pacientes con asma, crisis más frecuentes y sintomatología activa. En consecuencia, el asma tiene un impacto socioeconómico considerable para el paciente y la sociedad en su conjunto, al igual que afecta la calidad de vida del paciente y su familia. En México, el paciente con asma puede recibir atención médica en los ámbitos pú-blico o privado, en los diferentes niveles de salud y por múltiples especialidades. Todas estas particularidades de la situación nacional indican la necesidad de un documento guía actualizado, con base amplia en múltiples gremios médicos, tanto de primer nivel de atención como de especialidad.El objetivo de la GUIMA 2017 es facilitar la reducción de la morbimortalidad por asma en México, no solo al mejorar el conocimiento acerca de esta patología, sino también al ayudar a la parte administrativa del Sector Salud a gestionar la selección y adquisición más precisa de los medicamentos necesarios para su tratamiento a nivel de la salud pública. Para tal fin se ofrecen lineamientos par...
The importance of the immunomodulatory effects of vitamin D has recently been associated with autoimmune and chronic inflammatory diseases. Vitamin D deficiency has been linked to the development of autoimmune conditions. Antiphospholipid syndrome is an autoimmune disease characterized by thrombotic events and obstetric complications in patients with antiphospholipid antibodies. Current data show that patients with antiphospholipid syndrome have a high prevalence of vitamin D deficiency even without classic risk factors. Several studies have suggested vitamin D may have anti-thrombotic functions. In antiphospholipid syndrome, low vitamin D serum levels have been associated with thrombotic manifestations, suggesting a possible protective role of vitamin D in antiphospholipid syndrome. This literature review presents current evidence on the haemostatic functions of vitamin D and their possible relationship with the clinical manifestations of antiphospholipid syndrome.
