Brief Summary

The MLC-R aims to create a large-scale registry that provides data on epidemiology, phenotypes, and disease trajectories of and health care for Long COVID at any age in Germany, which can be used for future clinical trials.

Detailed Description

Infections with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been observed in Germany since January 2020 and can result in acute coronavirus disease 2019 (COVID-19) as well as in long-term sequela, referred to as Long COVID. The umbrella term Long COVID comprises ongoing new SARS-CoV-2-associated symptoms later than four weeks from the onset of acute COVID-19. The term Post-COVID-Condition (PCC) was introduced by the WHO and stands for ongoing or new SARS-CoV-2-associated symptoms, which persisted for at least two months. These symptoms often include fatigue, brain fog, dyspnea, orthostatic intolerance, as well as exercise intolerance, with a worsening of symptoms after mild daily activities (post-exertional malaise, PEM). PCC can severely impair daily function, social participation, and health-related quality of life. The prevalence was estimated as up to 15% in infected people with pre-Omicron variants and lower with Omicron variants. Risk factors include female gender and pre-existing morbidity, with low risk in young children. The most severe form of PCC in people with initially mild or moderate COVID-19 is myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The prevalence of ME/CFS was shown to increase in the context of the pandemic. While progress has been made in deciphering the pathogenesis of acute COVID-19, the mechanisms of Long COVID/PCC are poorly understood. Increasing evidence indicates that remaining viral particles, as well as inflammation, altered microcirculation, dysfunction of the autonomic nervous system, and/or autoimmunity, may contribute.

With the web-based German MLC-R, we aim at deep phenotyping of PCC, identification of subtypes and risk factors, describing trajectories of the disease and patient journeys, and providing clinical data for future clinical trials. Patients are also invited to contribute biosamples for future translational research.

Primary Outcome Measures
NameTimeMethod
Phenotyping of Post-COVID condition: Medical History5 years

Routine assessment of the medical history, such as current and previous medication, vaccinations, comorbidities, and more, to achieve a profound and detailed Post-COVID condition phenotype.

Phenotyping of Post-COVID condition: Physical Examination5 years

Routine physical examination to achieve a profound and detailed Post-COVID condition phenotype.

Phenotyping of Post-COVID condition: Laboratory Parameters5 years

Measurement of a routine set of laboratory parameters including blood tests (cell count, C-reactive protein, organ function, immunoglobulins, antibodies, etc.) and urine/stool analysis (calprotectin, blood) to achieve a profound Post-COVID condition phenotype.

Phenotyping of Post-COVID condition: Functional Tests5 years

Technical exams (e.g. pulmonary function tests, electrocardiography, ultrasound, magnetic resonance imaging, etc.) will be performed as indicated to achieve a profound and detailed Post-COVID condition phenotype.

Secondary Outcome Measures
NameTimeMethod
Definition of Sub-cohorts5 years

Sub-cohorts are identified using routine data. By means of e.g. trigger, disease severity (e.g. Bell score from the worst outcome with 0 points till the best outcome with 100 points), daily functioning (e.g. SF-36).

Analyzation of numbers of physicians involved5 years

Patients' journeys will be analyzed in terms of the number of physicians involved

Evaluation of kind of spezializations of physicians involved5 years

Patients' journeys will be analyzed in terms of the kind of specializations of physicians involved

Evaluation of kind of the latency of symptoms5 years

Patients' journeys will be analyzed in terms of the kind of specializations of physicians involved

Evaluation of kind of the onset of therapy5 years

Patients' journeys will be analyzed in terms of the latency from symptom onset to initiation of therapy in months.

Prevalence of Comorbidities5 years

Prevalence of comorbidities of patients with Post-COVID condition will be analyzed.

Identification of Candidate Prognostic Markers5 years

Correlation of routine clinical data (e.g., medical history, routine laboratory, and physical examination) with clinical outcome (e.g., health-related quality of life, disease severity, and social participation).
