    Background: Previous studies have focused on the clinical characteristics of hospitalized patients with the novel 2019 coronavirus disease MESHD (COVID-19). Limited data are available for convalescent patients. This study aimed to evaluate the clinical characteristics of discharged COVID-19 patients.Methods: In this retrospective study, we extracted data for 134 convalescent patients with COVID-19 in Guizhou Provincial Staff Hospital from February 15 to March 31, 2020. Cases were analyzed on the basis of demographic, clinical, and laboratory data as well as radiological features. Results: Of 134 convalescent patients with COVID-19, 19 (14.2%) were severe cases, while 115 (85.8%) were non-severe cases. The median patient age TRANS was 33 years (IQR, 21.8 to 46.3), and the cohort included 69 men and 65 women. Compared with non-severe cases, severe patients were older and had more chronic comorbidities, especially hypertension MESHD hypertension HP, diabetes, and thyroid disease MESHD (P<0.05). Leukopenia MESHD Leukopenia HP was present in 32.1% of the convalescent patients and lymphocytopenia was present in 6.7%, both of which were more common in severe patients. 48 (35.8%) of discharged patients had elevated levels of alanine aminotransferase, which was more common in adults TRANS than in children TRANS (40.2% vs 13.6%, P=0.018). A normal chest CT was found in 61 (45.5%) patients during rehabilitation. Severe patients had more ground-glass opacity, bilateral patchy shadowing, and fibrosis MESHD. No significant differences were observed in the positive rate of IgG and/or IgM antibodies SERO between severe and non-severe patients.Conclusion: Leukopenia MESHD Leukopenia HP, lymphopenia MESHD lymphopenia HP, ground-glass opacity, and fibrosis MESHD are common in discharged severe COVID-19 patients, and liver injury is common in discharged adult TRANS patients. We suggest physicians develop follow-up treatment plans based on the different clinical characteristics of convalescent patients.

    Background: A pandemic of severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) is on-going. Clinical characters of afebrile cases infected with SARS-CoV-2 remain poorly understood and informations are limited on the duration of SARS-CoV-2 viral positivity.Methods: We performed a single-center retrospective study of 125 patients with SARS-CoV-2 infection MESHD in Beijing Ditan Hospital, Capital Medical University from January 26 to March 15, 2020. Differences were compared among patients with/without fever MESHD fever HP. Risk factors for the duration of SARS-CoV-2 viral positivity were evaluated.Results: A total of 125 patients with positive SARS-CoV-2 test were enrolled, including 38 afebrile patients and 87 febrile patients. On admission, a total of 35 (28%) patients had leukopenia MESHD leukopenia HP, 41 (32.8%) had lymphopenia MESHD lymphopenia HP and 6 (4.8%) had thrombocytopenia MESHD thrombocytopenia HP. 73 patients (58.4%) had a loss of T lymphocytes and 96 patients (76.8%) had decreased CD4+T lymphocytes. Compared with febrile cases, afebrile patients had a significantly higher white blood SERO cell count (P = 0.001), total lymphocytes (P < 0.001), platelet count (P < 0.001), T lymphocytes (P = 0.013) and CD8+ T lymphocytes (P = 0.002). The median SARS-CoV-2 viral positivity duration of these 125 patients was 14 days (IQR, 10-30 days) and for febrile and afebrile group were 12 days (IQR, 9-23 days) and 23 days (IQR, 11-30 days) respectively. Multivariate Cox regression results showed that the fever MESHD fever HP [hazard ratio (HR) = 0.497, P = 0.006], young age TRANS (HR = 0.965, P = 0.018), and higher count of platelet (HR = 4.555, P = 0.034) were the predominant risk factor for the SARS-CoV-2 viral positivity duration.Conclusion: The SARS-CoV-2 virial positivity duration of the afebrile group was significantly longer than that in the febrile group. Fever MESHD Fever HP, young age TRANS and a higher count of platelet were the independent protective factors for a shorter SARS-CoV-2 RNA positivity duration.

    Background In December, 2019, a type of novel coronavirus which was designated novel coronavirus 2019 (2019-nCoV) by World Health Organization (WHO) occurred in Wuhan, Hubei, China. The epidemiological and clinical characteristics of those patients under 18 years old in the recovery stage are limited. To compare the difference of epidemiological and clinical characteristics of COVID-19 involving 25 patients under 18 years old in recovery stage between confirmed and asymptomatic infections MESHD asymptomatic TRANS.Methods Retrospective, single-center cohort study of COVID-19 involving 25 patients under 18 years old in the recovery stage at Guizhou Provincial Staff Hospital in Guiyang, China, from January 29, to March 31, 2020; final date of follow-up was April 22. Epidemiological, demographic, clinical, laboratory, radiological, and treatment data were collected and analyzed. Epidemiological and clinical characteristics of confirmed COVID-19 infections and asymptomatic MESHD asymptomatic TRANS infections MESHD were compared.Results Among the 25 COVID infections MESHD under 18 years old, 16 (64%) were mild or moderate confirmed cases TRANS, and 9 (36%) were asymptomatic TRANS. The shortest treatment period was 6 days, the longest 26 days, and the average treatment period 14 days. Four cases (44.4%) had visited Wuhan or had a living story in the city. There were 9 (100%) asymptomatic TRANS cases were familial cluster outbreak, with an average infection MESHD number was 6 cases among all families. The number of asymptomatic TRANS COVID-19 infections’ Leukopenia MESHD Leukopenia HP were significantly more than confirmed cases TRANS (p = 0.04).Conclusions Leukopenia MESHD Leukopenia HP mostly occurred in asymptomatic TRANS COVID-19 infections MESHD under 18 years old compared with the confirmed patients.

    Background: Multicenter retrospective comparison of the first high-resolution computed tomography (HRCT) findings of coronavirus disease MESHD 2019 (COVID-19) and other viral pneumonias MESHD pneumonias HP.Methods: We retrospectively collected clinical and imaging data from 254 cases of confirmed TRANS viral pneumonia MESHD pneumonia HP in 20 hospitals in Yunnan Province, China, from March 1, 2015, to March 15, 2020. According to the virus responsible for the pneumonia MESHD pneumonia HP, the pneumonias MESHD pneumonias HP were divided into non-COVID-19 (133 cases) and COVID-19 (121 cases). The non-COVID-19 pneumonias MESHD pneumonias HP included 3 types: cytomegalovirus (CMV) (31 cases), influenza A virus (82 cases), and influenza B virus (20 cases). The differences in the basic clinical characteristics, lesion distribution, location and imaging signs among the four viral pneumonias MESHD pneumonias HP were analyzed and compared.Results: Fever MESHD Fever HP and cough MESHD cough HP were the most common clinical symptoms of the four viral pneumonias MESHD pneumonias HP. Compared with the COVID-19 patients, the non-COVID-19 patients had higher proportions of fatigue MESHD fatigue HP, sore throat, expectorant and chest tightness HP (all p<0.000). In addition, in the CMV pneumonia MESHD pneumonia HP patients, the proportion of patients with combined acquired immunodeficiency syndrome MESHD immunodeficiency HP syndrome (AIDS) and leukopenia MESHD leukopenia HP were high (all p<0.000). Comparisons of the imaging findings of the four viral pneumonias MESHD pneumonias HP showed that pulmonary lesions of COVID-19 were more likely to occur in the peripheral and lower lobes of both lungs, while those of CMV pneumonia MESHD pneumonia HP were diffusely distributed. Compared with the non-COVID-19 pneumonias MESHD pneumonias HP, COVID-19 pneumonia MESHD pneumonia HP was more likely to present as ground-glass opacity (GGO), intralobular interstitial thickening HP, vascular thickening and halo sign (all p<0.05). In addition, in the early stage of COVID-19, extensive consolidation, fibrous stripes, subpleural lines, crazy-paving pattern, tree-in-bud HP, mediastinal lymphadenectasis, pleural thickening HP and pleural effusion MESHD pleural effusion HP were rare (all p<0.05).Conclusion: The HRCT findings of COVID-19 pneumonia MESHD pneumonia HP and other viral pneumonias MESHD pneumonias HP overlapped significantly, but many important differential imaging features could still be observed.

    Background: Novel coronavirus pneumonia MESHD pneumonia HP (COVID-19) outbreak caused by severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) has rapidly spread over the globe. The knowledge about SARS-CoV-2 infection MESHD in immunocompromised patients was limited. Case presentation: We presented here two human immunodeficiency HP virus (HIV)-infected cases with laboratory confirmed COVID-19 and clinically confirmed COVID-19, respectively. The patients both presented with fever MESHD fever HP at illness onset and patchy shadows in radiological images of lungs. Laboratory findings revealed leukopenia MESHD leukopenia HP, lymphopenia MESHD lymphopenia HP and positive anti-HIV antibody SERO. The younger case had a moderate course and was discharged after a 28-day hospitalization. However, the elder case with multiple comorbidities developed dyspnea MESHD dyspnea HP and died on the fourth day after admission. Conclusions: Combining our data with two case reports, we summarize that disease MESHD course varies in HIV-infected patients with COVID-19. More attention should be paid to the management of these patients. Whether there is any difference about clinical characteristics and prognosis of COVID-19 between HIV-infected and non-HIV infected patients, remains to be further investigated.

    Background: The clinical and CT manifestations of COVID-19 pneumonia MESHD pneumonia HP and non-COVID-19 pneumonia MESHD pneumonia HP in the same period have not been compared in detail. The purpose of this study is to analyze the clinical and CT manifestations of COVID-19 pneumonia MESHD pneumonia HP and perform a comparison of those isolated patients for presumed COVID-19 infection MESHD and of non-COVID-19 pneumonia MESHD pneumonia HP in the same period.Methods: 173 patients with pneumonia MESHD pneumonia HP from January 1, 2020 to March 20, 2020 were retrospectively enrolled and classified into three groups: patients with COVID-19 pneumonia MESHD pneumonia HP (Group I, N=4), patients in hospital-isolation for presumed COVID-19 pneumonia MESHD pneumonia HP (Group Ⅱ, N=5), and patients with non-COVID-19 pneumonia MESHD pneumonia HP (Group III, N=163). Clinical symptoms, laboratory test results and CT imaging features were compared among three groups.Results: Fever MESHD Fever HP and cough MESHD cough HP were the most common clinical symptoms in the three groups. 30/163 (18.4%) patients were asymptomatic TRANS in Group III. Leukopenia MESHD Leukopenia HP, lymphocytopenia, and elevated C-reactive protein was identified in 1 (25%), 1 (25%), and 1 (25%) patient in Group I; 1 (20%), 1 (20%), and 2 (40%) patients in Group II; 10/157 (6.4%), 33/157(21.0%), and 94/136 (69.1%) patients in Group III. Demarcated GGO/mixed GGO, ill-defined GGO/mixed GGO, consolidation, centrilobular nodule, tree-in bud opacity, bilateral involvement, peripheral distribution, posterior part/lower lobe predilection was observed in 3/4 (75%), 2/4 (50%), 4/4 (100%), 2/4 (50%), 0, 3/4 (75%), 3/4 (75%), and 2/4 (50%) patients, respectively in Group I; 1/5 (20%), 5/5 (100%), 4/5 (80%), 4/5 (80%), 3/5 (60%), 4/5 (80%), 2/5 (40%), and 3/5 (60%) patients in Group Ⅱ; 1/163 (0.6%), 87/163 (54.3%), 115/163 (70.6%), 117/163 (71.8%), 95/163 (58.3%), 52/163 (31.9%), 9/163 (5.5%), and 9/163 (5.5%) patients in Group III, respectively.Conclusions: Demarcated GGO and consolidation prefer the diagnosis of COVID-19 pneumonia MESHD pneumonia HP, whereas ill-defined GGO and consolidation, centrilobular nodule surrounded by GGO, and tree-in-bud opacity are preferred for non-COVID-19 pneumonia MESHD pneumonia HP. chest CT has potential in early identification of COVID-19 and implementation of isolation for appropriate case.

    Background: The international outbreak of respiratory illness termed coronavirus disease MESHD 2019 (COVID-19) began in December 2019 that has affected more than 0.8 million individuals. To date, there are no specific therapeutic agents for coronavirus infections MESHD. One of the drugs that have an effective role in improving the condition of patients with COVID-19 is hydroxychloroquine (HCQ). This drug is not a definitive treatment for this disease MESHD and has a supportive role. Like all medications, HCQ has side effects and may occur in COVID-19 patients. Stevens-Johnson syndrome MESHD caused by HCQ is very rare.Case presentation: A 42-year-old woman, presented with fever MESHD fever HP and dry cough MESHD cough HP in the past two days to her family physician. Lab tests revealed elevated lactate dehydrogenase (LDH, 648 units/liter (U/L)), C-reactive protein level (CRP, 52 milligrams/Liter (mg/L), normal: <10 mg/L), aspartate aminotransferase (AST, 59 U/L, normal: 10-40 U/L), thrombocytopenia MESHD thrombocytopenia HP, and leukopenia MESHD leukopenia HP. Mild bilateral patchy ground-glass opacity was seen in lung CT-Scan. Due to COVID-19 pandemic and clinical findings, the nasopharyngeal swab test was done and SARS-CoV-2 nucleic acid was detected by RT-PCR. HCQ 200 mg twice daily was started. After two days, the patient presented with a pruritic erythematous maculopapular rash and flat atypical targets that started from the distal of upper extremities and rapidly, involved the entire body, and torn blisters MESHD which were only be seen as ulcers MESHD on orolabial area. The Nikolsky sign was positive. Due to the likelihood of a drug reaction, HCQ was discontinued, and COVID-19 treatment was changed to lopinavir/ritonavir (LPV/RTV) 400 mg twice daily. Finally, she was discharged after five days with nonpruritic scalded skin on the distal of upper extremities. Conclusions: It is worth noting that although HCQ appears to be safe and has mild side effects, however, the boundary between therapeutic and toxic doses is narrow and severe disorders of their use can life-threatening. One of the side effects of HCQ is SJS caused by the drug, and given the worldwide pandemic of COVID-19 and the increasing need for this drug, we need to be careful about its use in order to control and manage the side effects of this drug.

    Background: Coronavirus disease MESHD 2019 (COVID-19), caused by severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2), was declared a global pandemic by World Health Organization in March 2020. Case Presentation:We report a case of a 51-year-old Chinese woman who was evacuated from Wuhan, China and diagnosed with COVID-19 infection MESHD at a Southern California quarantine facility. Clinical course was notable for high fevers MESHD fevers HP, night sweats HP, productive cough HP cough MESHD, transient leukopenia MESHD leukopenia HP, lymphopenia MESHD lymphopenia HP, thrombocytopenia MESHD thrombocytopenia HP, and transaminitis. Evolving hypoxia MESHD and infiltrates on chest imaging warranted the trial of an investigational antiviral drug - remdesivir. The patient recovered and was discharged after two weeks of hospitalization. Conclusion:This case highlights the patient’s clinical course including diagnostic work-up, medical management, and challenges in defining non-infectivity in a relatively unknown disease MESHD.

    The coronavirus disease MESHD (COVID-19) is currently prevalent worldwide. We analysed the occurrence of diarrhoea of these patients after treatment. All patients were treated with nebulised α-interferon and oral administration of Lopinavir/Ritonavir tablets. Of the 62 patients, 38 (61.3%) developed diarrhoea after treatment. Of these 38 cases, 63.2% (24/38 cases) had their first diarrhoea within 24 hours after medication. Only 13.2% (5/38 cases) had more than 5 bowel movements per day with a maximum of 10 per day. Patients with diarrhoea had lower white blood SERO cell counts. Leukopenia MESHD Leukopenia HP was a risk factor for the development of diarrhoea. We conclude that COVID-19 patients had a relatively high rate of diarrhoea after treatment. Lopinavir/Ritonavir was speculated to contribute to diarrhea MESHD diarrhea HP, which is a common adverse drug reaction to Lopinavir/Ritonavir. Patients with reduced white blood SERO cell counts at admission may be more likely to develop diarrhoea after admission.

    Background: Outbreak of COVID-19 has brought catastrophe to huge numbers of families. However, even though numerous tragedies occurred, there were few reports about family cluster infection MESHD in the academic journals. Methods: The electronic medical records of 10 COVID-19 patients in a big family were retrospectively reviewed and analyzed.Results: These 10 patients, 4 males TRANS and 6 females TRANS, were infected through two successive family feasts during Spring Festival. The infection MESHD source was a family member TRANS at asymptomatic TRANS state, who lived in Hubei but travelled TRANS to Nanjing. The median age TRANS of these 10 patients was 61.5, with the oldest 95 and youngest 38. The incubation period TRANS varied from 3 to 17 days, with the median of 5.5. Of them, 2 patients were asymptomatic TRANS. The most common symptoms at onset TRANS were fever MESHD fever HP (6/10) and dry cough MESHD cough HP (6/10). All of them displayed lesions on the chest CT. 40% of them had leukopenia MESHD leukopenia HP, neutropenia MESHD neutropenia HP and lymphopenia MESHD lymphopenia HP. After anti-virus treatment, all the patients significantly improved and were discharged. Conclusions: SARS-Cov-2 was highly contagious and so crafty that a varied incubation period TRANS did exist. Part of patients might be asymptomatic TRANS, which was the potential source of transmission TRANS. More measures for protection or quarantine should be taken at home if family member TRANS had travel TRANS history nearby the epidemic area.
