[Complaints and clinical findings six months after COVID-19: outpatient follow-up at the University Medical Center Freiburg].

Abstract

BACKGROUND\n\u2002Increasing evidence suggests that some patients suffer from persistent symptoms for months after recovery from acute COVID-19. However, the clinical phenotype and its pathogenesis remain unclear. We here present data on complaints and results of a diagnostic workup of patients presenting to the post-COVID clinic at the University Medical Center Freiburg.\n\n\nMETHODS\n\u2002Retrospective data analysis of persistently symptomatic patients presenting to our clinic at least 6 months after onset of acute COVID-19. All patients were assessed by a doctor and routine laboratory analysis was carried out. Quality of life was assessed using SF-36 questionnaire. In case of specific persisting symptoms, further organ-specific diagnostic evaluation was performed, and patients were referred to respective departments/specialists.\n\n\nFINDINGS\n\u2002132 Patients (58 male, 74 female; mean age 53.8\xa0years) presented to our clinic at least 6 months after COVID-19. 79 (60\u200a%) had been treated as outpatients and 53 (40\u200a%) as inpatients. Most common complaints were persistent fatigue (82\u200a%) and dyspnea on exertion (61\u200a%). Further common complaints were impairments of concentration (54\u200a%), insomnia (43\u200a%), and impairments of smell or taste (35\u200a%). Quality of life was reduced in all sections of the SF-36 questionnaire, yielding a reduced working capacity. Significant pathological findings in laboratory, echocardiographic and radiological work-up were rare. Impairments in lung function tests were more common in previously hospitalized patients.\n\n\nCONCLUSION\n\u2002Patients presenting 6 months after onset of acute COVID-19 suffer from a diverse spectrum of symptoms with impaired quality of life, also referred to as Long COVID or Post-Acute Sequelae of SARS-CoV-2 infection (PASC). Further research is needed to determine the frequency of these post-COVID syndromes and their pathogenesis, natural course and treatment options. Evaluation and management should be multi-disciplinary.
