Dins el programa TLC organitzat per la UVIC, el dia 24 de novembre i en format telem\u00e0tic, el Dr. Bonaventura Clotet, Cap de servei de Malalties Infeccioses de l\u2019Hospital Universitari Germans Trias i Pujol de Badalona. Director de l\u2019Institut de Recerca de la Sida IrsiCaixa. Catedr\u00e0tic Infeccioses de la Facultat de Medicina UVIC- ens ha parlat sobre la Covid 19, el sistema immunitari i les vacunes.<\/p>\n

Ha parlat sobre la malaltia, la seva simptomatologia i les seves fases, la variaci\u00f3 de la c\u00e0rrega viral durant la infecci\u00f3 -la qual disminuiex de forma significativa al cap d\u2019uns 10 dies despr\u00e9s de l\u2019inici-, la detecci\u00f3 `per PCR (es detecta l\u2019ARN v\u00edric-i per testos serol\u00f2gics – es detecten immunoglobulines- i la seva transmissi\u00f3.
\nPer al tractament de la Covid 19 cal seguir una triple via: administrar heparina (anticoagulant), antiv\u00edrics o anticossos monoclonals (neutralitzen el virus) i antiinflamatoris.<\/p>\n

Immunitat: la immunitat a la Covid 19 \u00e9s a partir de la immunitat innata (interfer\u00f3: mol\u00e8cula pr\u00f2pia del sistema immunitari que actua com a senyal d\u2019alerta i provoca el bloqueig de la infecci\u00f3 viral) i la immunitat adaptativa, tant per immunitat humoral, atrav\u00e9s de la s\u00edntesi d\u2019anticossos (immunoglobulines) elaborats per les c\u00e8l\u00b7lules plasm\u00e0tiques derivades dels limf\u00f2cits B, com per immunitat cel\u00b7lular, a partir de limf\u00f2cits T (dits CD8 i CD4), els quals poden atacar c\u00e8l\u00b7lules infectades per virus.
\nS\u2019assolir\u00e0 la immunitat de grup quan un 60% de la poblaci\u00f3 estigui immunitzada.<\/p>\n

Vacunes: de les moltes que s\u2019estan elaborant, les tres m\u00e9s representatives fins al moment s\u00f3n la de la casa Pfizer, amb un 90% d\u2019efic\u00e0cia (proporciona m-RNA que porta informaci\u00f3 perqu\u00e8 el cos produeixi una part del virus -esp\u00edcula S- i aix\u00ed el sistema immunitari hi pugui donar resposta), la de Moderna amb un 95% d\u2019efic\u00e0cia, utilitza un adenovirus hum\u00e0 com a vehicle per a fer arribar a les c\u00e8l\u00b7lules m-RNA v\u00edric, mentre que Astrazeneca (Oxford), introdueix la informaci\u00f3 gen\u00e8tica per a les esp\u00edcules del virus a partir de DNA transportat per en un adenovirus de ximpanz\u00e9.<\/p>\n

Referent a les vacunes necessitem saber:
\n. Com protegeixen la poblaci\u00f3 m\u00e9s gran i vulnerable (tenen immunosenesc\u00e8ncia)
\n. Si generen defenses a llarg termini
\n. Si poden disminuir la c\u00e0rrega viral dels que s\u2019infecten i, per tant, disminuir la transmissi\u00f3
\n. Distribuci\u00f3 de les vacunes perqu\u00e8 arribi arreu<\/p>\n

Trigarem molts mesos fins que la poblaci\u00f3 estigui immunitzada, no podem deixar d\u2019anar amb mascaretes.<\/p>\n
