Changes in spirometry and pulmonary diffusing capacity in Mexican Hispanics approximately one year after having...

This observational longitudinal study was conducted at the Long-term follow-up COVID-19 Clinic in Mérida, Mexico, from March to August 2021. A total of 100 patients hospitalized for severe COVID-19 were enrolled. Inclusion criteria required participants to be adults over 18, recovering from severe COVID-19 as defined by the World Health Organization (oxygen saturation below 90 %, severe pneumonia, or signs of severe respiratory distress). Exclusion criteria included pneumonia from non-SARS-CoV-2 causes, mild or moderate COVID-19, or a single follow-up evaluation. Pulmonary function tests were conducted at approximately 100 and 400 days after diagnosis. The dataset includes 82 patients with baseline and follow-up spirometry, pulmonary diffusing capacity and alveolar volume. Morbidity history and fibrosis scores from high-resolution CT scans were also obtained. Finally, fitted z-scores for spirometry and pulmonary diffusing capacity were acquired from established reference equations. The freely accessible data (Version 4) is provided in both SPSS (.sav) and .csv format. at the Mendeley Data cloud-based repository and includes nominal data, ordinal data, and scalar data.
