Brief summary in lay language
The investigation of protein fragment patterns in urine (urine proteomics) is intended to predict the severity of Covid-19 disease.
Brief summary in scientific language
Three urine samples are collected from each patient or sent from home, a first urine sample at the time of the first presentation (day 0-1), a second on day 4-5 and a third on day 10-14, to determine the best time to collect the sample for prognostic purposes. A classification into moderate, severe and critical courses of disease is carried out according to the WHO classification criteria (to be found at: https://www.who.int/docs/default-source/coronaviruse/who-china-joint-mission-on-covid-19-final-report.pdf), which also includes intensive care, ventilation and death as patient-relevant endpoints. The urine samples are collected, prepared, measured by CE-MS, evaluated and patient-specific peptide lists prepared according to established SOP specifications and in conformity with ISO standard 13485/2016. The peptide profiles of the first 250 patients at all sample times will be used to verify the 31 peptide markers associated with the severity of SARS-CoV-2 infection identified in the pilot study. The higher statistical power will also be used to search for additional peptide markers that show a correlation to the severity of SARS-CoV-2 infection. Based on the results of the statistical analysis, the COVID31 classification model established in a previous pilot study will be adapted. By classifying the first 250 patients at all sample times, the threshold value for a positive test result is determined with regard to the prediction of a critical course of disease in total cross-validation. The completion of the first phase of model optimization is documented before the model is then validated prospectively in routine operation on a further 750 patients using the predetermined threshold value for a positive test result. The final evaluation of the study will be performed using the established statistical methods Receiver Operating Characteristics and Precision Recall curves, as well as univariate and multivariate Cox regression analyses.

- Study abstract:
- Background The SARS-CoV-2 pandemic is a worldwide challenge. The CRIT-CoV-U pilot study generated a urinary proteomic biomarker consisting of 50 peptides (COV50), which predicted death and disease progression from SARS-CoV-2. After the interim analysis presented for the German Government, here, we aimed to analyse the full dataset to consolidate the findings and propose potential clinical applications of this biomarker. Methods CRIT-CoV-U was a prospective multicentre cohort study. In eight European countries (Austria, France, Germany, Greece, North Macedonia, Poland, Spain, and Sweden), 1012 adults with PCR-confirmed COVID-19 were followed up for death and progression along the 8-point WHO scale. Capillary electrophoresis coupled with mass spectrometry was used for urinary proteomic profiling. Statistical methods included logistic regression and receiver operating characteristic curve analysis with a comparison of the area under curve (AUC) between nested models. Hospitalisation costs were derived from the care facility corresponding with the Markov chain probability of reaching WHO scores ranging from 3 to 8 and flat-rate hospitalisation costs adjusted for the gross per capita domestic product of each country. Findings From June 30 to Nov 19, 2020, 228 participants were recruited, and from April 30, 2020, to April 14, 2021, 784 participants were recruited, resulting in a total of 1012 participants. The entry WHO scores were 1–3 in 445 (44%) participants, 4–5 in 529 (52%) participants, and 6 in 38 (4%) participants; and of all participants, 119 died and 271 had disease progression. The odds ratio (OR) associated with COV50 in all 1012 participants for death was 2·44 (95% CI 2·05–2·92) unadjusted and 1·67 (1·34–2·07) when adjusted for sex, age, BMI, comorbidities, and baseline WHO score; and for disease progression, the OR was 1·79 (1·60–2·01) when unadjusted and 1·63 (1·41–1·91) when adjusted (p<0·0001 for all). The predictive accuracy of the optimised COV50 thresholds was 74·4% (71·6–77·1%) for mortality (threshold 0·47) and 67·4% (64·4–70·3%) for disease progression (threshold 0·04). When adjusted for covariables and the baseline WHO score, these thresholds improved AUCs from 0·835 to 0·853 (p=0·033) for death and from 0·697 to 0·730 (p=0·0008) for progression. Of 196 participants who received ambulatory care, 194 (99%) did not reach the 0·04 threshold. The cost reductions associated with 1 day less hospitalisation per 1000 participants were million Euro (M€) 0·887 (5–95% percentile interval 0·730–1·039) in participants at a low risk (COV50 <0·04) and M€2·098 (1·839-2·365) in participants at a high risk (COV50 ≥0·04). Interpretation The urinary proteomic COV50 marker might be predictive of adverse COVID-19 outcomes. Even in people with mild-to-moderate PCR-confirmed infections (WHO scores 1–4), the 0·04 COV50 threshold justifies earlier drug treatment, thereby potentially reducing the number of days in hospital and associated costs
