Disease progression of 213 patients hospitalized with Covid-19 in the Czech Republic in March-October 2020: An exploratory analysis.

We collected a multi-centric retrospective dataset of patients (N = 213) who were admitted to ten hospitals in Czech Republic and tested positive for SARS-CoV-2 during the early phases of the pandemic in March-October 2020. The dataset contains baseline patient characteristics, breathing support required, pharmacological treatment received and multiple markers on daily resolution. Patients in the dataset were treated with hydroxychloroquine (N = 108), azithromycin (N = 72), favipiravir (N = 9), convalescent plasma (N = 7), dexamethasone (N = 4) and remdesivir (N = 3), often in combination. To explore association between treatments and patient outcomes we performed multiverse analysis, observing how the conclusions change between defensible choices of statistical model, predictors included in the model and other analytical degrees of freedom. Weak evidence to constrain the potential efficacy of azithromycin and favipiravir can be extracted from the data. Additionally, we performed external validation of several proposed prognostic models for Covid-19 severity showing that they mostly perform unsatisfactorily on our dataset.

Clinical and laboratory characteristics of the COVID-19 disease in adult patients.

BACKGROUND: In December 2019, a new coronavirus, SARS-CoV-2, appeared in Wuhan, China. This virus is the cause of the COVID-19 disease. This infection later spread to the whole world. The goal of this article is to present the clinical and laboratory characteristics of patients with COVID-19 treated in the Faculty Hospital Pilsen. METHODS: In this monocentric, retrospective study, clinical and biochemical data of 89 adult patients with COVID-19 was analyzed. These patients were in the care of the Faculty Hospital Pilsen between March 14 and April 7. RESULTS: In this cohort, made up of 89 patients, 63 were treated as outpatients and 26 were hospitalized. 10 patients required intensive care. The most common symptoms among patients were cough and fever. Dyspnea was present in 29 patients. A CT scan showed bilateral pneumonia in 23 of the admitted patients. Fever and bilateral pneumonia were significantly more common in patients ≥ 60 years old (p=0.047, and p=0.001, respectively). Of lab results, the patients in intensive care had significantly higher values of C-reactive protein, procalcitonin, lactate dehydrogenase, interleukin 6, myoglobin and ferritin. CONCLUSION: The most common symptoms of COVID-19 are fever and cough. These two symptoms are simultaneously present in more than half the cases. Approximately 1/10th of patients requires intensive care. Higher values of lactate dehydrogenase, myoglobin and ferritin on patient admission appear to be a strong predictive factor of the patient's status progressing into requiring ICU attention.
