Abstract
Background and Objective: The ambiguity and lack of consensus in both domestic (including national protocols) and international sources regarding the efficacy of doxycycline in improving clinical symptoms and preventing disease progression in patients with CORONAVIRUS Disease 2019 (Covid-19) led to the decision to conduct this study. The objective was to evaluate the effectiveness of doxycycline in the clinical course and improvement of outpatients with the disease..
Materials and Methods: The present clinical trial was conducted on 82 patients diagnosed with the disease (in accordance with the established clinical criteria) who presented at Shahid Beheshti Hospital during the years 2021-2022 and did not require hospitalization. The control group received the standard care and medication for patients with the disease. In addition to these care measures, the intervention group received doxycycline capsules at a dose of 100 mg twice daily for a duration of 10 days. The need for hospitalization, mortality, complete recovery, and the progression of clinical symptoms were monitored and compared for 30 days in both patient groups. For the purpose of comparing the disease outcomes based on nominal and ordinal categorical variables, the Chi-square test (Fisher's exact test) was utilized, while paired t-test was employed for the purpose of comparing quantitative variables.
Results: There were 41 patients in the intervention group and 37 patients in the control group with no statistically significant difference in terms of average age, gender, and clinical symptoms at the time of referral. Hospitalization rate was 8 cases (19.5%) in the intervention group and 9 cases (24.3%) in the control group (P=0.784). One month after treatment, 21 (56.8%) patients in the control group and 29 (70.7%) patients in the intervention group had complete recovery. In both groups, the percentage of arterial oxygen saturation increased over time in both groups and this increase was greater in the intervention group, the difference between the two groups was statistically significant (P=0.001).
Conclusion: doxycycline can be effective in outpatients with covid-19 due to faster recovery and less need for hospitalization.
