RESUMEN

Coronavirus disease 2019 (COVID-19) was first reported in Wuhan, Hubei Province, China in December 2019. At present, COVID-19 has emerged as a global pandemic. The clinical features of this disease are not fully understood, especially the interaction of COVID-19 and preexisting comorbidities and how these together further impair the immune system. In this case study, we report a COVID-19 patient with cirrhosis. A 73-year-old woman with cirrhosis reported a fever and cough on February 6, 2020. CT of the chest indicated an infection in her bilateral lungs. She tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The woman was treated with lopinavir and ritonavir tablets and interferon alpha-2b injection, but there was no obvious effect. Although this patient was basically asymptomatic after 2 days in the hospital, the inflammation of the bilateral lungs was slow to subside as shown in CT of the chest. In addition, the white blood cell count (WBC), absolute neutrophil count, and absolute lymphocyte count remained decreased and the result of real-time reverse transcription polymerase chain reaction (PCR) (rRT-PCR) assay was still positive for SARS-CoV-2 on hospital day 28. After infusion of plasma from a recovered COVID-19 patient four times, the patient tested negative for SARS-CoV-2. She was discharged on March 13, 2020. This patient tested negative for SARS-CoV-2 after infusion of plasma from a recovered COVID-19 patient four times. Cirrhosis could impair the homeostatic role of the liver in the systemic immune response, which may affect the removal of SARS-CoV-2. This could lead to a diminished therapeutic effect of COVID-19. Thus, clinicians should pay more attention to COVID-19 patients with cirrhosis.

RESUMEN

INTRODUCTION: The coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread throughout China and worldwide. Little is known about the dynamic changes in the patient immune responses to SARS-CoV-2 and how different responses are correlated with disease severity and outcomes. METHODS: Seventy-four patients with confirmed COVID-19 were enrolled in this prospective research. The demographic information, medical history, symptoms, signs and laboratory results were analyzed and compared between severe and non-severe patients. The leukocytes, lymphocyte subsets and inflammatory cytokines were longitudinally collected. RESULTS: Of the 74 patients included, 17 suffered from severe disease. The severe patients tended be older (65.29 ± 12.33 years vs. 45.37 ± 18.66 years) and had a greater degree of underlying disease (41.18% vs. 24.56%), lower baseline lymphocyte counts [0.64 (0.46-0.95) × 109 vs. 1.27 (0.95-1.70) × 109], higher neutrophil-lymphocyte ratios [NLRs; 3.76 (3.15-5.51) vs. 2.07 (1.48-2.93)] and lower baseline eosinophil counts [0 (0-0.01) × 109 vs. 0.03 (0.01-0.06) × 109] than those in non-severe patients. The baseline helper T (Th) cells (335.47 vs. 666.46/µl), suppressor T(Ts) cells (158 vs. 334/µl), B cells (95 vs. 210/µl) and natural killer (NK) cells (52 vs. 122/µl) were significantly decreased in severe cases compared to that in non-severe cases. In addition, the baseline neutrophils were positively correlated with the severity of COVID-19, and the baseline lymphocytes were negatively correlated with the severity of COVID-19. The dynamic change of T cells, Th cells and IFN-γ in the severe cases were parallel to the amelioration of the disease. CONCLUSIONS: Collectively, our study provides novel information on the kinetics of the immune responses in a cohort of COVID-19 patients with different disease severities. Furthermore, our study indicates that both innate and adaptive immune responses correlate with better clinical outcomes.

RESUMEN

With the outbreak of coronavirus disease-19 (COVID-19), Changsha faced an increasing burden of treating the Wuhan migrants and their infected patients. This study is a retrospective, single-center case series of the 238 consecutive hospitalized patients with confirmed COVID-19 at the First Hospital of Changsha city, China, from 01/21 to 02/14, 2020; the final date of follow-up was 02/27, 2020. Of 238 patients 43.7% visited Wuhan, 58.4% got in touch with Wuhan people, and 47.5% had contacted with diagnosed patients. 37.8% patients had family members infected. 190 cases had mild / general disease, and 48 cases had severe / critical disease. Compared to mild or general patients, more severe or critical patients visited Wuhan (59.6% vs 40.2%; P=0.02) and contacted with Wuhan people (74.5% vs 55.0%; P=0.02). All patients received antiviral treatment, including Lopinavir / Ritonavir (29.3%), Interferon (14.6%) and their combination (40.6%), Arbidol (6.7%), Xuebijing (7.1%) and Chloroquine phosphate (1.3%). Severe and critical patients received glucocorticoid, Gamma-globulin and oxygen inhalation. Some received mechanic ventilation support. As of 02/27, 161 patients discharged. The median length of hospital stay was 13 days. The 10-, 14-, 20- and 28-day discharge rate was 19.1%, 42.8%, 65.0% and 76.4%, respectively. No hospital-related transmission was observed.

RESUMEN

The COVID-19 pandemic causes severe morbidity and mortality. This multi-country study aimed to explore risk factors that drive mortality in COVID-19 patients who received neither dexamethasone nor remdesivir. We analyzed a cohort of 568 survivors and 507 non-survivors from China, European regions, and North America. Elderly males ≥70 years accounted for only 25% of survivors, but this rate was significantly higher in non-survivors from China (55%), European regions (63%), and North America (47%). Compared with survivors, non-survivors had more incidences of comorbidities such as cerebrovascular disease and chronic obstructive pulmonary disease (COPD, p-values<0.05). Survival analyses revealed age, male gender, shortness of breath, cerebrovascular disease, and COPD as mortality-associated factors. Survival time from symptom onset was significantly shorter in elderly versus young patients (median: 29 versus 62 days), males versus females (median: 46 versus 59 days), and patients with versus without comorbidities (mean: 41 versus 61 days). Mortality risk was higher in elderly males with comorbidities than in young females without comorbidities (p-value<0.01). Elderly male survivors with comorbidities also had longer hospital stays than other survivors (25 versus 18.5 days, p-value<0.01). Overall, the high mortality risk in elderly males with COVID-19-associated comorbidities supports early prevention and critical care for elderly populations.

RESUMEN

BACKGROUND: In December 2019, the novel coronavirus disease 2019 (COVID-19) emerged in Wuhan, Hubei Province, China. It rapidly spread and many cases were identified in multiple countries, posing a global health problem. Here, we report the first patient cured of COVID-19 infection in Changsha, China, and the symptoms, diagnosis, treatment, and management of this patient are all described in this report. CASE PRESENTATION: A 57-year-old woman developed cough and fever after returning to Changsha from Wuhan on January 9, 2020. She tested positive for COVID-19 infection, a diagnosis which was supported by chest CT. The patient was treated with lopinavir and ritonavir tablets and interferon alfa-2b injection. A low dose of glucocorticoids was used for a short period to control bilateral lung immune response, and this patient avoided being crushed by cytokine storms that might have occurred. The clinical condition of this patient improved, and a COVID-19 assay conducted on January 25, 2020 generated negative results. This patient recovered and was discharged on January 30, 2020. CONCLUSIONS: Currently, there are numerous reports on COVID-19 infections focusing on the disease's epidemiological and clinical characteristics. This case describes the symptoms, diagnosis, treatment, and management of a patient cured of COVID-19 infection, which may serve as reference for future cases, while further studies are needed.

RESUMEN

OBJECTIVES: To analyze the clinical characteristics in patients of coronavirus disease 2019 (COVID-19) complicated with liver injury, to explore the relationship between COVID-19 clinical classification and liver injury, and to elucidate whether COVID-19 complicated with hepatitis B virus can aggravate liver injury. METHODS: The abnormal liver function in 110 patients in the First Hospital of Changsha, who were confirmed COVID-19 and admitted to the designated hospital from January 17, 2020 to February 20, 2020, wereretrospectively analyzed. The detection indexes included serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBIL). RESULTS: A total of 49.1% of the COVID-19 patients had liver injury. There were significant difference in the ALT, AST, ALB (all P<0.05), but there was no significant difference in the TBIL (P>0.05) between the severe (critical) patients and the general (light) patients. There was also no significant difference in the liver function injury between the HBsAg-positive COVID-19 patients and HBsAg-negative COVID-19 patients (P>0.05). Acute liver injury was not found to be a direct cause of death in the patients. CONCLUSIONS: In the COVID-19 patients, the incidence of liver injury is high with the increase of ALT and AST and the decrease of ALB. Severe and critical patients have obvious liver injury, and those patients complicated with hepatitis B virus infection don't show aggravated liver injury.

RESUMEN

In December 2019, a cluster of coronavirus Disease 2019 (COVID-19) occurred in Wuhan, Hubei Province, China. The present study was conducted to report the clinical characteristics of 201 COVID-19 patients in Changsha, China, a city outside of Wuhan. All of the patients with confirmed COVID-19 were admitted to the First Hospital of Changsha City, the designated hospital for COVID-19 assigned by the Changsha City Government. The clinical and epidemiological characteristics, data of laboratory, radiological picture, treatment, and outcomes records of 201 COVID-19 patients were collected using electronic medical records. This study population consisted of 201 hospitalized patients with laboratory-confirmed COVID-19 in Changsha by April 28, 2020. The median age of the patients was 45 years (IQR 34-59). About half (50.7%) of the patients were male, and most of the infected patients were staff (96 [47.8%]). Concerning the epidemiologic history, the number of patients linked to Wuhan was 92 (45.8%). The most common symptoms were fever (125 [62.2%]), dry cough (118 [58.7%]), fatigue (65 [32.3%]), and pharyngalgia (31 [15.4%]). One hundred and forty-four (71.6%) enrolled patients showed bilateral pneumonia. Fifty-four (26.9%) patients showed unilateral involvement, and three (1.5%) patients showed no abnormal signs or symptoms. The laboratory findings differed significantly between the Intensive Care Unit (ICU) and non-ICU groups. Compared with non-ICU patients, ICU patients had depressed white blood cell (WBC), neutrocytes, lymphocytes, and prolonged prothrombin time (PT). Moreover, higher plasma levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), procalcitonin (PCT), alanine aminotransferase (ALA), aspartate aminotransferase (AST), creatine kinase (CK), creatine kinase-MB (CK-MB), creatinine (CREA), and lactate dehydrogenase (LDH) were detected in the ICU group. In this single-center study of 201 COVID-19 patients in Changsha, China, 22.4% of patients were admitted to ICU. Based on our findings, we propose that the risk of cellular immune deficiency, hepatic injury, and kidney injury should be monitored. Previous reports focused on the clinical features of patients from Wuhan, China. With the global epidemic of COVID-19, we should pay more attention to the clinical and epidemiological characteristics of patients outside of Wuhan.

RESUMEN

BACKGROUND: The antiviral effects of Novaferon, a potent antiviral protein drug, on COVID-19 was evaluated in the laboratory, and in a randomized, open-label, parallel-group trial. METHODS: In the laboratory, Novaferon's inhibition of viral replication in cells infected with SARS-CoV-2, and prevention of SARS-CoV-2 entry into healthy cells was determined. Antiviral effects of Novaferon in COVID-19 patients with treatment of Novaferon, Novaferon plus Lopinavir/Ritonavir, or Lopinavir/Ritonavir were evaluated. The primary endpoint was the SARS-CoV-2 clearance rates on day six of treatment, and the secondary endpoint was the time to SARS-CoV-2 clearance. RESULTS: Novaferon inhibited viral replication (EC50=1.02ng/ml), and prevented viral infection (EC50=0.10ng/ml). Results from the 89 enrolled COVID-19 patients showed that both Novaferon and Novaferon plus Lopinavir/Ritonavir groups had significantly higher viral clearance rates on day six than Lopinavir/Ritonavir group (50.0% vs. 24.1%, p=0.0400, and 60.0% vs. 24.1%, p=0.0053). The median time to viral clearance was six days, six days, and nine days for three groups, respectively, a 3-day reduction in both the Novaferon and Novaferon plus Lopinavir/Ritonavir groups compared with the Lopinavir/Ritonavir group. CONCLUSIONS: Novaferon exhibited anti-SARS-CoV-2 effects in vitro and in COVID-19 patients. These data justify further evaluation of Novaferon.

RESUMEN

BACKGROUND: SARS-CoV-2 causes high mortality risk in older patients. This study aims to characterize the clinical features of older and younger SARS-CoV-2 infected patients. RESULTS: A total of 239 patients were divided into the younger group (<60 years; n=181) and the older group (≥60 years; n=58). In both groups, fever and cough were common symptoms. However, dyspnea was more frequent in older patients than younger patients (20.7% versus 9.9%, p=0.032). Compared with younger patients, older patients harbored more severe cases (37.9% versus 17.1%, p=0.001) and comorbidities (58.6% versus 21.0%, p<0.001) such as hypertension and diabetes. The baseline values of eosinophils and C-reactive protein were abnormal in older and younger groups. From baseline to day 14, significant decreases of three biomarkers (C-reactive protein, hemoglobin, albumin) and dramatic increases of three biomarkers (lymphocytes, platelets, blood urea nitrogen) were observed in older patients. CONCLUSION: Older and younger patients exhibited differences in dyspnea, comorbidities, and proportions of severe cases. Moreover, the disease progression of SARS-CoV-2 in older patients is observed with the dynamics of laboratory biomarkers, supporting their potential use in disease monitoring. METHODS: We retrieved clinical symptoms, laboratory findings, comorbidities, and hospitalization information of SARS-CoV-2 cases in Changsha.

RESUMEN

BACKGROUND: Since December 8, 2019, an epidemic of coronavirus disease 2019 (COVID-19) has spread rapidly, but information about children with COVID-19 is limited. METHODS: This retrospective and the single-center study were done at the Public Health Clinic Center of Changsha, Hunan, China. We identified all hospitalized children diagnosed with COVID-19 between January 8, 2019 and February 19, 2020, in Changsha. Epidemiological and clinical data of these children were collected and analyzed. Outcomes were followed until February 26th, 2020. RESULTS: By February 19, 2020, nine pediatric patients were identified as having 2019-nCoV infection in Changsha. Six children had a family exposure and could provide the exact dates of close contact with someone who was confirmed to have 2019-nCoV infection, among whom the median incubation period was 7.5 days. The initial symptoms of the nine children were mild, including fever (3/9), diarrhea (2/9), cough (1/9), and sore throat (1/9), two had no symptoms. Two of the enrolled patients showed small ground-glass opacity of chest computed tomography scan. As of February 26, six patients had a negative RT-PCR for 2019-nCoV and were discharged. The median time from exposure to a negative RT-PCR was 14 days. CONCLUSIONS: The clinical symptoms of the new coronavirus infection in children were not typical and showed a less aggressive clinical course than teenage and adult patients. Children who have a familial clustering or have a family member with a definite diagnosis should be reported to ensure a timely diagnosis.
