Background In Patients suffering from post-COVID syndrome, in addition to physical limitations, cognitive limitations, fatigue, dyspnea as well as depression and anxiety disorders may also be present. Up to now (as of May 2022), approx. 514 million people worldwide have been infected with SARS-CoV-2, in Germany this affects approx. 25 million. In Germany, 2.5 million people could potentially be affected by post-COVID syndrome. Post-COVID is thus a highly relevant public health issue. So far, there is no specific causal therapy for the post-COVID syndrome, but with multimodal symptom-oriented rehabilitation, the course can be favourably influenced. However, there is no study yet that focuses on patients in different rehabilitation indications and compares the focal symptomatology and coping strategies as well as the patients' benefit per indication. Methods/design As first objective, pulmonal, cardiac, neurological, cognitive or/and psychological functional impairments in rehabilitation patients after COVID-19 disease will be described. The second objective is the differentiated review of the specific rehabilitation measures, in the short term and in the longer term for the purpose of future prognoses and optimisation of therapeutic interventions. This prospective, non-randomised, controlled longitudinal study, plus multi-group comparisons will take place in seven rehabilitation clinics of different specialisations: cardiological rehab, pneumological rehab, neurological rehab, psychosomatic rehab. Within 12 months, 1000 cases across all participating centres will be included. Somatic and psychological testing will be conducted at three measurement points: Admission (t0), discharge (t1), 6-montas Catamnesis (t2). The patients receive the usual care according to the respective rehabilitation priorities, adapted to the special challenges of post-COVID symptoms. Patients of the post-COVID outpatient clinic without rehabilitation will be used as a control group. Discussion This study will precisely assess the extent to which subclinical neurological or/and psychological impairments are present in post-COVID-19 rehabilitation and the results will help, developing, providing and evaluating appropriate treatment concepts. This may also have relevant implications for the improvement of physical ability and quality of life in post-COVID-19 patients and increase the probability of return to work.

Recently, unexpectedly high virus-specific IgG4 levels were reported after more than two mRNA vaccinations. Class switch towards IgG4 occurs after long-term antigen exposure, downregulates immune responses and is associated with several autoimmune diseases.Here, we examined differences in antigen-specific IgG subtypes in serum samples from 64 Post-COVID patients and an equally sized cohort of convalescent controls.In both cohorts, the relative amounts of spike protein-specific IgG subtypes were comparable. IgG1 was the most frequent, followed by IgG3, IgG2, and IgG4. A difference between cohorts was observed only for IgG2, which was significantly lower in the Post-COVID cohort. Further analysis of the reactive IgG4 revealed a small but significant difference for the spike protein receptor-binding domain but not for the spike ectodomain.Since the total IgG4 levels are very low, we do not expect a biologically relevant role in Post-COVID syndrome. However, reduced virus-specific IgG2 levels could contribute to the persistence of SARS-CoV-2, causing chronic inflammation in the setting of Post-COVID syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
