Preprints with The Lancet is a collaboration between The Lancet Group of journals and SSRN to facilitate the open sharing of preprints for early engagement, community comment, and collaboration. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early-stage research papers that have not been peer-reviewed. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. The findings should not be used for clinical or public health decision-making or presented without highlighting these facts. For more information, please see the FAQs.

Background: The pneumonia associated with the novel coronavirus (Severe Acute Respiratory Syndrome Coronavirus 2, SARS-CoV-2) is breaking out in Wuhan, China. We aimed to clarify the differences of clinical, laboratory, radiological, and outcome characteristics between SARS-CoV-2 infective pneumonia (Corona Virus Disease 2019, COVID-19) patients with diarrhea and those without.
Methods: In this retrospective, single-center study, we included 84 confirmed patients of SARS-CoV-2 pneumonia in Wuhan Union Hospital from Jan 19 to Feb 7. Patients were confirmed by Real-Time Reverse-Transcriptase–Polymerase-Chain-Reaction Testing in pharyngeal swab. The clinical manifestations, laboratory examinations, imaging manifestations and outcomes of patients with diarrhea and those without diarrhea were compared.
Findings: Of 84 patients with SARS-CoV-2 pneumonia, diarrhea occurred in 26 (31%) patients. Patients with diarrhea, compared to those without diarrhea, were more likely to have headache (57.7% vs 22.4%, p = 0.003), myalgia or fatigue (94.4% vs 50.0%,p = 0.010), cough(84.6% vs 44.8%, p < 0.001), sputum production(53.8% vs 20.7%, p = 0.0004), nausea(38.5% vs 10.3, p < 0.005) and vomiting(19.2% vs 1.7%, p = 0.010). The duration of fever and dyspnea in patients with diarrhea was significantly longer than those without diarrhea (10.5±4.7 vs 7.6±3.4(day), p = 0.005; 8.1±3.2 vs 4.7±2.3(day), p = 0.002; respectively). There are no differences in most of the laboratory findings between these two groups, including lymphocyte count, creatinine, lactate dehydrogenase and D-Dimer. The positive rate of testing SARS-CoV-2 from stool of COVID-19 patients with diarrhea was much higher than that of patients without (69.2% vs 17.2%, p < 0.001). As of Feb 19, the negative rate in retesting SARS-CoV-2 from throat swab of diarrhea group was significantly lower, as compared with non-diarrhea group (76.9% vs 96.6%, p = 0.010). Of 76 COVID-19 patients whose throat swab test have turn to be negative for SARS-CoV-2, the positive rate in retesting SARS-CoV-2 from stool was significantly higher in diarrhea group, as compared to non-diarrhea group (45.0% vs 19.6%, p = 0.039).
Interpretation: COVID-19 patients with diarrhea suffered discomfort longer, as compared with COVID-19 pneumonia patients without diarrhea. The elimination of SARS-CoV-2 from digestive system took much more time than that from respiratory system, in some COVID-19 patients with diarrhea.
