Tenofovir Disoproxil Fumarate in the Treatment of COVID-19: Evaluation of 78 Patients.

One of the drugs that has been suggested for the treatment of SARS-CoV-2 infection is tenofovir disoproxil (TDF). Herein, it was aimed to evaluate the outcomes of TDF receiving COVID-19 cases in terms of day 7-10 PCR negativity and day 30 survival. Patients who received TDF due to PCR-confirmed COVID-19 between 27.04.2021 and 31.12.2021 were included in our study. The primary outcome was considered to be 7-10 days of PCR negativity, while the secondary outcome was considered 30-day survival after diagnosis of COVID-19. Patients who died before completing the treatment period (7-10 days) were also considered as PCR failures. Data were analyzed both in terms of intention to treat basis and in the subgroup that survived to the end of treatment. A total of 78 patients (30 women, mean age: 61.15±18.5 years) met the inclusion criteria. In the intention to treat analysis group, one-month-mortality was 44.87% (35/78) in the overall cohort. In the end of treatment analysis group, one-month-mortality was 29.5% (18/61) in the overall cohort. Day 7-10 PCR negativity was detected in 55.7% of the overall EOT cohort. Our data suggest that TDF may be an alternative salvage treatment option in antiviral unresponsive patients. We suggest evaluating TDF in well-designed controlled trials involving treatment-naïve cases.
