Background: COVID-19, the latest outbreak of infectious disease, has caused huge medical challenges to China and the entire globe. No unified diagnostic standard has been formulated. The initial diagnosis remains based on the positive of nucleic acid tests. However, early nucleic acid tests were identified to be negative in some patients, whereas the patients exhibited characteristic CT changes of lung, and positive test results appeared after repeated nucleic acid tests, having caused the failure to diagnose these patients early. The study aimed to delve into the relationships between initial nucleic acid testing and early lung CT changes in patients with COVID-19. Method: In accordance with the latest COVID-19 diagnostic criteria, 69 patients diagnosed with COVID-19 treated in the infected V ward of Xiaogan Central Hospital from 2020/1/25 to 2020/2/6 were retrospectively analyzed. The consistency between the first COVID-19 nucleic acid test positive and lung CT changes was studied. In addition, the sensitivity and specificity of CT and initial nucleic acid were studied. Result: The Kappa coefficient of initial nucleic acid positive changes and lung CT changes was −1.52. With a positive nucleic acid test as the gold standard, the sensitivity of lung CT was 12.00 %, 95 % CI: 4.6-24.3; with the changes of CT as the gold standard, the sensitivity of nucleic acid positive was 30.16 %, 95 % CI: 19.2−43.0. Conclusion: The consistency between the initial positive nucleic acid test and the CT changes in the lungs is poor; low sensitivity was achieved for initial nucleic acid detection and CT changes.
ResultsUsing the SSPS16.0 software package, Kappa coefficient was adopted to measure the consistency of nucleic acid and the changes of lung CT. The initial Kappa of positive nucleic acid changes and lung CT changes reached −1.52 (Tables 1, 2). Based on the gold standard of
The etiology of unexplained periodic fever is often complex, and hereditary factors play an important role. This article describes a 26-year-old chinese women with intermittent fever for 9 years, with 10-year history of IgA nephropathy. Her fever is relieved during pregnancy, but after a baby is born, fever reappears, accompanied by headache, gasping after activity, chest pain, abdominal pain, blood in the stool, ataxia, intermittent back erythema, skin biopsy suggests amyloidosis, the autoinflammatory PLCG2 associated antibody deficiency and immune dysregulation was diagnosed by genetic testing. The fever was gradually relieved after treatment with rilonacept.
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.
