RESUMEN

The COVID-19 pandemic has had a significant impact on the health and economy of the global population. Even after recovery from the disease, post-COVID-19 symptoms, such as pulmonary fibrosis, continue to be a concern. This narrative review aims to address pulmonary fibrosis (PF) from various perspectives, including the fibrotic mechanisms involved in idiopathic and COVID-19-induced pulmonary fibrosis. On the other hand, we also discuss the current therapeutic drugs in use, as well as those undergoing clinical or preclinical evaluation. Additionally, this article will address various biomarkers with usefulness for PF prediction, diagnosis, treatment, prognosis, and severity assessment in order to provide better treatment strategies for patients with this disease.

RESUMEN

SARS-CoV-2 is the etiological agent of COVID-19 and may evolve from asymptomatic disease to fatal outcomes. Real-time reverse-transcription polymerase chain reaction (RT-PCR) screening is the gold standard to diagnose severe accurate respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but this test is not 100% accurate, as false negatives can occur. We aimed to evaluate the potential false-negative results in hospitalized patients suspected of viral respiratory disease but with a negative previous SARS-CoV-2 RT-PCR and analyze variables that may increase the success of COVID-19 diagnosis in this group of patients. A total of 55 hospitalized patients suspected of viral respiratory disease but with a previous negative RT-PCR result for SARS-CoV-2 were included. All the participants had clinical findings related to COVID-19 and underwent a second SARS-CoV-2 RT-PCR. Chest-computed axial tomography (CT) was used as an auxiliary tool for COVID-19 diagnosis. After the second test, 36 patients (65.5%) were positive for SARS-CoV-2 (COVID-19 group), and 19 patients (34.5%) were negative (controls). There were differences between the groups in the platelet count and the levels of D-dimer, procalcitonin, and glucose (p < 0.05). Chest CT scans categorized as COVID-19 Reporting and Data System 5 (CO-RADS 5) were more frequent in the COVID-19 group than in the control group (91.7% vs. 52.6%; p = 0.003). CO-RADS 5 remained an independent predictor of COVID-19 diagnosis in a second SARS-CoV-2 screening (p = 0.013; odds ratio = 7.0, 95% confidence interval 1.5−32.7). In conclusion, chest CT classified as CO-RADS 5 was an independent predictor of a positive second SARS-CoV-2 RT-PCR, increasing the odds of COVID-19 diagnosis by seven times. Based on our results, in hospitalized patients with a chest CT classified as CO-RADS 5, a second SARS-CoV-2 RT-PCR test should be mandatory when the first one is negative. This approach could increase SARS-CoV-2 detection up to 65% and could allow for isolation and treatment, thus improving the patient outcome and avoiding further contagion.

RESUMEN

INTRODUCTION: Coronavirus disease 19 (COVID-19) has been a global public health emergency, with 209.89 million cases of infection with SARS-CoV-2 recorded, resulting in 4,401,675 deaths. After recuperation, it is probable that COVID-19 patients have sequelae of the disease. This study aimed to evaluate the respiratory anatomical-functional sequelae in Mexican patients who recovered from COVID-19. METHODOLOGY: This study included twenty-four patients who recovered from COVID-19 and eight non-infected patients (controls). Participants were screened for SARS-CoV-2 and the presence of IgM/IgG antibodies. Pulmonary function and lung anatomical abnormalities were evaluated by spirometry and computerized tomography. RESULTS: A total of 45.8% of the patients had pulmonary function with obstructive patterns: 70.8% of recovered cases had COVID-19 Reporting and Data System (CO-RADS) 1, 20.8% CO-RADS 3 and 16.7% CO-RADS 4. A total of 35.3% of patients with CO-RADS 1 also showed bilateral nodal growth; 70.8% of patients tested positive for IgG and 8.4% for IgG/IgM, and 20.8% tested negative for both antibodies. CONCLUSIONS: There were respiratory anatomical and functional sequelae in Mexican patients who recovered from COVID-19, with a high occurrence of pulmonary obstructive patterns in the study population. These observations indicate the importance of the routine evaluation of sequelae in Mexican patients who recovered from COVID-19 and the need for strict follow-up to improve the quality of life of these patients.
