Objective To describe the clinical data from the first 108 patients seen in the Mayo Clinic post–COVID-19 care clinic (PCOCC). Methods After Institutional Review Board approval, we reviewed the charts of the first 108 patients seen between January 19, 2021, and April 29, 2021, in the PCOCC and abstracted from the electronic medical record into a standardized database to facilitate analysis. Patients were grouped into phenotypes by expert review. Results Most of the patients seen in our clinic were female (75%; 81/108), and the median age at presentation was 46 years (interquartile range, 37 to 55 years). All had post-acute sequelae of SARS-CoV-2 infection, with 6 clinical phenotypes being identified: fatigue predominant (n=69), dyspnea predominant (n=23), myalgia predominant (n=6), orthostasis predominant (n=6), chest pain predominant (n=3), and headache predominant (n=1). The fatigue-predominant phenotype was more common in women, and the dyspnea-predominant phenotype was more common in men. Interleukin 6 (IL-6) was elevated in 61% of patients (69% of women; P =.0046), which was more common than elevation in C-reactive protein and erythrocyte sedimentation rate, identified in 17% and 20% of cases, respectively. Conclusion In our PCOCC, we observed several distinct clinical phenotypes. Fatigue predominance was the most common presentation and was associated with elevated IL-6 levels and female sex. Dyspnea predominance was more common in men and was not associated with elevated IL-6 levels. IL-6 levels were more likely than erythrocyte sedimentation rate and C-reactive protein to be elevated in patients with post-acute sequelae of SARS-CoV-2 infection.

Objective Constrictive bronchiolitis (CB) is a poorly understood pulmonary manifestation of primary Sjögren syndrome (pSS). We aimed to clarify the presenting clinicoradiologic features and clinical course of pSS-associated CB through a retrospective cohort study. Methods We retrospectively identified 11 patients with pSS and CB (defined by mosaic pattern with air trapping on computed tomography) encountered at our institution over 9 years from 2007 to 2015. Presenting clinical features, laboratory results, radiologic findings, and clinical course were analyzed. Results Our patients were mostly women (91%), with a median age 53 years (range, 31–76 years) at the time of pulmonary symptom (dyspnea or cough) onset. Most (64%) were nonsmokers. Average interval between diagnosis of pSS and the onset of pulmonary symptoms was 4.4 years; in 4 patients (36%), CB was the presenting manifestation of pSS. Chest radiographs were normal (67%) or demonstrated hyperinflation (33%). Pulmonary function testing demonstrated airflow obstruction in 7 patients (63%), and 2 patients (18%) had an isolated reduction in diffusing capacity, whereas the remaining 2 patients manifested mixed physiology or normal results. Surgical lung biopsy was performed in 2 patients and confirmed the diagnosis of CB in both. Treatment was variable among our patients included glucocorticoids, hydroxychloroquine, mycophenolate mofetil, and cyclophosphamide. Among 6 patients with follow-up computed tomography and pulmonary function, the results remained stable or worsened. Conclusions Constrictive bronchiolitis is a rare extraglandular manifestation and can sometimes be the presenting manifestation of pSS. This pulmonary manifestation is associated with an indolent clinical course and does not respond well to immunosuppressive therapy.
