Impact of viral co-infection on clinical outcomes and mortality of COVID-19 patients: a study from Saudi Arabia
Keywords:
COVID-19, virus, coinfection, outcomes, clinical, mortality, hospitalization, impactAbstract
Background: In COVID-19 patients undetected co-infections may have severe clinical implications associated with prolonged hospitalization, ICU admission and mortality. Therefore, we aimed to investigate the impact of viral co-infections on the outcomes of hospitalized patients with COVID-19 in a large tertiary Saudi Arabian Hospital.
Methods: A total of 178 adult patients with confirmed SARS-CoV-2 who were hospitalized at the Armed Forces Hospital Southern Region (AFHSR), Saudi Arabia, from March 1st to June 30th 2022, were enrolled. Real-time PCR for the detection of viral co‑infections was carried out. Cases (SARS-CoV-2 with viral coinfections) and control (SARS-CoV-2 mono-infection) groups were compared.
Results: 12/178 (7%) of enrolled COVID-19 patients had viral coinfections. 82/178 (46%) of patients were males. 58% of patients had comorbidities. During the study period, 4/12 (33%) and 21/166 (13%) cases and control patients died, p=0.047, respectively. Duration of hospitalization was the only significant independent factor associated with SARS-CoV-2 coinfections, OR 1.140, 95% CI 1.020–1.274, p=0.021.
Conclusions: The findings of this study from a large tertiary Saudi Arabian Center revealed a prevalence of 7% for SARS-CoV-2 viral coinfections. SARS-CoV-2 coinfected patients had a significantly prolonged duration of hospitalization and higher mortality than those with SARS-CoV-2 alone. Future studies are needed.
