In questo studio retrospettivo, sono stati analizzati possibili cambiamenti nelle sottopopolazioni linfocitarie in pazienti ospedalizzati affetti da malattia da Coronavirus19 (COVID-19). Sono stati arruolati 107 pazienti COVID-19 di età superiore ai 18 anni, ricoverati presso l’Azienda Ospedaliera di Alessandria con diagnosi confermata di infezione da SARS-CoV-2 mediante Reverse Transcriptase- Polymerase Chain Reaction (RT-PCR), che hanno eseguito l’analisi delle sottopopolazioni linfocitarie, tra il 01 marzo 2020 e il 31 maggio 2021. I pazienti sono stati suddivisi in due gruppi, in base alle manifestazioni cliniche: Gruppo 1 (malattia non grave (n=44)) e Gruppo 2 (malattia grave (n=63)), secondo le indicazioni dell’Organizzazione Mondiale della Sanità (OMS). Per il confronto tra i due gruppi di pazienti, la significatività statistica è stata testata con il test di Mann-Whitney e il test del Chi-quadro. Nel gruppo di pazienti con malattia grave, l’analisi delle cellule ematiche ha mostrato una riduzione significativa della conta di linfociti totali, dei linfociti CD3 assoluti e dei linfociti CD8, nonché una riduzione significativa della percentuale di monociti e un aumento molto significativo della conta dei neutrofili. Dai risultati ottenuti, si può affermare che la linfocitopenia è associata alla progressione della malattia e ad un aumento della mortalità.
