Drugs and natural products for the treatment of COVID-19 during 2020, the first year of the pandemic / Fármacos y productos naturales para el tratamiento de la COVID-19 durante 2020, el primer año de la pandemia

Abstract This work aimed to show which treatments showed efficacy against coronavirus disease 2019 (COVID-19); therefore, the results of 37 clinical trials started in 2020 and completed in 2021 are reviewed and discussed here. These were selected from databases, excluding vaccines, computational studies, in silico, in vitro, and those with hyperimmune sera from recovered patients. We found 34 drugs, one vitamin, and one herbal remedy with pharmacological activity against symptomatic COVID-19. They reduced mortality, disease progression, or recovery time. For each treatment, the identifier and type of trial, the severity of the disease, the sponsor, the country where the trial was conducted, and the trial results are presented. The drugs were classified according to their mechanism of action. Several drugs that reduced mortality also reduced inflammation in the most severe cases. These include some that are not considered anti-inflammatory, such as Aviptadil, pyridostigmine bromide, anakinra, imatinib, baricitinib, and bevacizumab, as well as the combination of ivermectin, aspirin, dexamethasone, and enoxaparin. Nigella sativa seeds with honey have also been reported to have therapeutic activity. On the other hand, tofacitinib, novaferon with ritonavir, and lopinavir were also effective, as well as in combination with antiviral therapies such as danoprevir with ritonavir. The natural products colchicine and Vitamin D3 were only effective in patients with mild-to-moderate COVID-19, as was hydroxychloroquine. Drug repositioning has been the main tool in the search for effective therapies by expanding the pharmacological options available to patients.

Resumen El objetivo del presente trabajo fue conocer qué tratamientos mostraron efectividad contra COVID-19, para lo cual se revisan y discuten los resultados de 37 estudios clínicos iniciados durante 2020 y concluidos en 2021. Estos fueron seleccionados de bases de datos, excluyendo vacunas, estudios computacionales, in silico, in vitro y con sueros hiperinmunes de pacientes recuperados. Se documentaron 34 fármacos, una vitamina y un remedio herbolario, con actividad farmacológica ante COVID-19 sintomático. Estos redujeron la mortalidad, el progreso de la enfermedad, o el tiempo de recuperación. Para cada tratamiento se presenta identificador y tipo de estudio, la gravedad de la enfermedad, patrocinador, país donde se realizó, así como sus resultados. Los fármacos se clasificaron de acuerdo con su mecanismo de acción. Varios fármacos que redujeron la mortalidad también disminuyeron la inflamación en los casos más graves. Esto incluyendo algunos no considerados antiinflamatorios, como el aviptadil, el bromuro de piridostigmina, el anakinra, el imatinib, el baricitinib y el bevacizumab, así como la combinación de ivermectina, aspirina, dexametasona y enoxaparina. También se reportaron con actividad terapéutica las semillas de Nigella sativa con miel. Además, resultaron efectivos el tofacitinib, el novaferón con ritonavir y lopinavir, así como los antivirales en terapias combinadas como el danoprevir con ritonavir. Los productos naturales colchicina y vitamina D3, solo tuvieron actividad en los pacientes en estado leve a moderado de la COVID-19, así como la hidroxicloroquina. El reposicionamiento de fármacos fue la principal herramienta para buscar terapias efectivas ampliando las opciones farmacológicas accesibles a los pacientes.

Association between loneliness and mental health among nurses: a cross-sectional research in China

This study explored the association between loneliness and mental health among nurses in China during the COVID-19 pandemic. This cross-sectional study was conducted from March to April 2022. We enrolled 2,811 nurses from a tertiary hospital in China. Demographic characteristics, lifestyle factors, work-related factors, and psychological characteristics were collected from participants via a self-reported questionnaire. Loneliness was measured with the three-item short form of the Revised UCLA Loneliness Scale, and the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder (GAD-7) scale were used to measure mental health. Adjusted odds ratios (ORs) and 95% confidence intervals (CI) were determined using binary logistic regression. Among participants in this study, 12.0% (337) experienced loneliness, and 7.8% (219) and 6.7% (189) reported depression and anxiety, respectively. The loneliness scores were categorized into three levels (3, 4-6, and 7-9). For depression, compared with the lowest reference, the ORs and 95% CI across the tertile were 1.31 (0.69-1.84) and 2.53 (1.11-5.76) after adjustment, respectively, and the P-value for trend was 0.045. For anxiety, compared with the lowest reference, the ORs and 95%CI across the tertile were 1.84 (1.28-2.63) and 2.52 (1.57-4.10) after adjustment, respectively; the P-value for trend was 0.004. This study showed that loneliness was significantly associated with poor mental health among nurses during the COVID-19 pandemic. These findings suggested that medical establishments should offer interventions for nurses to prevent mental health problems by targeting this modifiable risk factor.

Objective To explore the application value of lymphocyte subsets combined with various cytokines in the disease progression of elderly patients with corona virus disease 2019(COVID-19).Methods From December 2022 to January 2023,146 elderly patients with COVID-19 diagnosed in the emergency ward of the Eighth Medical Center of PLA General Hospital were selected and divided into two groups according to the prognosis:127 cases in the COVID-19 survival group,19 cases in the COVID-19 death group.In addition,51 osteoporosis patients in geriatric medicine department were collected as control group.The proportion and absolute count of lymphocyte subsets(including T,B and NK cells),and 12 cytokines in plasma(including IL-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-17,TNF-α and IFN-γ)were compared between the control group and COVID-19 group,survival group and death group.The receiver operating characteristic(ROC)curve was used to evaluate its prognostic value in elderly patients with COVID-19 infection.Results Compared with the control group:① The proportion of NK cells in COVID-19 group was decreased,while the proportion of B cells was increased,and the differences were statistically significant(Z=-3.386,-4.140,all P<0.01).There was no significant difference in the proportion of T,CD8+T and CD4+T cells,and the differences were not statistically significant(Z=-1.244,-1.770,-0.951,all P>0.05).② The absolute numbers of T,CD8+T,CD4+T,NK and B cells in COVID-19 group were decreased,and the differences were statistically significant(Z=-9.418～-6.539,all P<0.01).③ The concentrations of IL-2,IL-6,IL-1β,IFN-γ,IL-8,IL-17,IL-12P70 and IL-10 in COVID-19 group were all increased,and the differences were statistically significant(Z=-8.851～-1.986,all P<0.05).There was no significant difference in the concentrations of IL-5,IFN-α,TNF-α and IL-4,and the differences were not statistically significant(Z=-0.460～-0.217,all P>0.05).Compared with the survival group:① There was no significant difference in the proportion of T,CD8+T,CD4+T,NK and B cells in the death group(Z=-1.873～-0.422,all P>0.05).② The absolute numbers of T,CD8+T and CD4+T cells in the death group were all decreased,and the differences were statistically significant(Z=-2.667,-2.287,-2.556,all P<0.05),while there was no significant difference in absolute numbers of NK and B cellsm and the differences were not statistically significant(Z=-1.934,-0.532,all P>0.05).③ The concentrations of IL-6,IFN-γ,IL-8,IL-17 and IL-10 in the death group were all increased,and the differences were not statistically significant(Z=-4.211～-2.655,all P<0.05),and there was no significant difference in the concentrations of IL-5,IFN-α,IL-2,IL-1β,IL-12p70,TNF-α and IL-4 the differences were not statistically significant(Z=-1.329～-0.279,all P>0.05).ROC curve analysis for the prognostic value of lymphocyte subsets combined with cytokines in elderly patients with COVID-19 showed that:the areas of total T cells,B cells and NK cells under ROC curve for predicting the prognosis of COVID-19 infection were 0.94,0.80 and 0.93,respectively.The areas of CD4+T cells and CD8+T cells under ROC curve for predicting the prognosis of COVID-19 infection were 0.93 and 0.90,respectively.The areas of IL-6,IFN-γ,IL-8,IL-17 and IL-10 in cytokines under the ROC curve for predicting the prognosis of COVID-19 infection were 0.91,0.71,0.87,0.74 and 0.90,respectively.However,the area of combined lymphocyte subsets and cytokines under ROC curve for predicting the prognosis of COVID-19 infection reached 0.99.Conclusion The immune status of elderly patients with COVID-19 was generally low.Evaluation of immune status has important clinical guidance significance in disease diagnosis,disease observation and prognosis.

Multisystem inflammatory syndrome in children in the context of coronavirus disease 2019 pandemic / 中国当代儿科杂志

Multisystem inflammatory syndrome in children (MIS-C) is a complex syndrome characterized by multi-organ involvement that has emerged in the context of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak. The clinical presentation of MIS-C is similar to Kawasaki disease but predominantly presents with fever and gastrointestinal symptoms, and severe cases can involve toxic shock and cardiac dysfunction. Epidemiological findings indicate that the majority of MIS-C patients test positive for SARS-CoV-2 antibodies. The pathogenesis and pathophysiology of MIS-C remain unclear, though immune dysregulation following SARS-CoV-2 infection is considered a major contributing factor. Current treatment approaches for MIS-C primarily involve intravenous immunoglobulin therapy and symptomatic supportive care. This review article provides a comprehensive overview of the definition, epidemiology, pathogenesis, clinical presentation, diagnosis, treatment, and prognosis of MIS-C.

Analysis of risk factors for severe illness caused by coronavirus disease 2019 in Fuzhou city / 解放军医学杂志

Objective To analyze the risk factors for severe illness caused by coronavirus disease 2019 in Fuzhou city.Methods The data of 4081 confirmed cases with current address in Fuzhou was collected from China Information System for Disease Control and Prevention from January 1 to June 30,2023.The epidemiological data of those cases was investigated such as the demographic characteristics,clinical manifestations and past medical history,etc.The risk factors of severe cases were analyzed by using the logistic regression.Results 4081 confirmed cases had been reported including 671 severe cases and 3410 non-severe cases.The demographic characteristics of severe cases,such as the proportion of male,age and current address in community were higher than that of non-severe cases,vaccination rate was lower than non-severe cases(59.02%vs.80.12%),the differences are statistically significant(P＜0.001).The clinical manifestations such as interval time between onset and visit(P=0.001),fever(P=0.002),difficulty in breathing/shortness of breath(P=0.001)were the factors related to severe illness.The past medical histories such as history of chronic lung disease,history of heart cerebrovascular disease of severe cases,were higher than that of non-severe cases(P＜0.001).Multivariate logistic regression showed that the male,the higher age,current address in community,no vaccination,the longer interval time between onset and visit,fever,difficulty in breathing/shortness of breath,the history of chronic lung disease,the history of heart cerebrovascular disease raised the risk of becoming severe cases.The healing time for severe cases was longer than that for non-severe cases(P＜0.001).Conclusion Sex,age,current address,vaccination,interval time between onset and visit,fever,difficulty in breathing/shortness of breath,history of chronic lung disease,and history of heart cerebrovascular disease are the influencing factors for severe illness.

Objective To explore the impact factors on early neurological deterioration(END)in patients with cerebral infarction combined with coronavirus disease 2019(COVID-19).Methods The clinical characteristics and laboratory of patients with acute ischemic stroke and COVID-19 in Brain Hospital Affiliated to Nanjing Medical University were retrospectively analyzed from December 15,2022 to January 15,2023.According to whether or not END occurred,all patients were divided into END group and non-END group.The clinical data of two groups were analyzed.Results A total of eligible 56 patients were included in this study,with 16 cases in END group and 40 cases in non-END group.The average age of END group(74.31±12.04)was older than non-END group(67.18±8.15)(P＜0.05).The proportion of previous history of coronary heart disease and diabetes were higher than non-END group(all P＜0.05).In terms of laboratory examination,the number of monocytes,C-reactive protein,glycated hemoglobin,lactate dehydrogenase,myoglobin,albumin,D-dimer,and fibrin degradation products in END group were significantly higher than that in non-END group(all P＜0.05).Logistic analysis showed that C-reactive protein is an independent risk factor for cerebral infarction combined with COVID-19(OR =1.084,95%CI:1.002-1.173,P＜0.05).Area under the ROC curve was0.825(95%CI:0.709-0.941,P＜0.001).Conclusions For patients with cerebral infarction combined with COVID-19,early neurological deterioration is more likely to occur in elderly patients with multiple underlying diseases,abnormal coagulation and inflammation indicators.Increased C-reactive protein has good predictive ability.

Acute pancreatitis complicated with diabetic ketoacidosis following COVID-19 mRNA vaccination: a case report / Journal of Rural Medicine

Objective: Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, COVID-19 vaccination has substantially reduced mortality and hospitalization rates worldwide, with rare adverse events reported in clinical settings. Herein, we present a case of acute pancreatitis complicated by diabetic ketoacidosis (DKA) following the third COVID-19 vaccination dose.Patient: A 72-year-old male with a history of diabetes mellitus developed generalized fatigue, mild epigastric pain, nausea, and frequent vomiting after receiving the COVID-19 vaccine.Results: Blood analysis revealed elevated levels of pancreatic enzymes, hyperglycemia, and acidemia. Computed tomography revealed evidence of acute pancreatitis, leading to a diagnosis of both DKA and acute pancreatitis. Treatment with a large volume of saline and intravenous insulin improved both DKA and acute pancreatitis. After a thorough examination, no other factors capable of causing acute pancreatitis were identified. Hence, we concluded that acute pancreatitis was induced by COVID-19 vaccination.Conclusion: Acute pancreatitis is a rare but potentially life-threatening adverse event associated with COVID-19 vaccination. Delaying the treatment or diagnosis of acute pancreatitis can increase mortality risk in patients with both acute pancreatitis and DKA. Hence, it is crucial for healthcare professionals to consider the potential occurrence of acute pancreatitis and DKA following COVID-19 vaccination.

Patient with Heterotopic Ossification Post-SARS‑CoV‑2 Infection Regained Ability to Walk Independently Indoors after Rehabilitation and Drug Therapy：A Case Report / The Japanese Journal of Rehabilitation Medicine

A 31-year-old woman infected with severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) at 33-weeks pregnant was subject to cesarean delivery due to a worsening respiratory condition. On the fourth day of illness, the patient was placed on a ventilator, with extracorporeal membrane oxygenation (ECMO) treatment initiated on the ninth day. Passive range of motion (ROM) training started on the day 33 of illness. She was weaned off ECMO on day 55 of illness and taken off of the ventilator on day 8. The tracheostomy tube was replaced with a speech cannula on day 87 of illness, at which time the patient began to complain of pain during passive ROM training. Plain X-ray photography and computed tomography (CT) showed ossification around the bilateral shoulder and hip joints, as well as on medial thighs, accompanied by an alkaline phosphatase (ALP) value of 942 U/L. She was subsequently diagnosed with heterotopic ossification, after which passive ROM training was changed to protective ROM training, in addition to treatment with indomethacin farnesyl and etidronate disodium. The patient was transferred to our hospital on day 122 of illness for the purpose of continuing rehabilitation. On day 155 of illness, ossification decreased on the medial thighs, according to CT. She was able to walk independently indoors and was discharged home on day 181 of illness. This case demonstrates the importance of checking the ALP levels and palpating the periarticular area in patients infected with SARS‑CoV‑2 before initiating passive ROM training, as well as being aware of any pain experienced during training. In the case of any abnormalities, assessing the ossification around the joints of extremities by imaging examination is a priority.

Introduction：Intracranial hemorrhage after severe coronavirus disease 2019 (COVID-19) is associated with increased mortality and unfavorable patient outcomes.Case：A man in his 60s with independent activities of daily living (ADL) was diagnosed with COVID-19, and placed on a ventilator on Day (D)-3 and VV-ECMO on D-5. On D-23, an emergency craniotomy was performed for a left acute subdural hematoma. The patient was weaned from VV-ECMO on D-27. On D-33, sitting was initiated. On D-36, the patient was weaned from the ventilator and began exercise therapy. The Glasgow coma score (GCS) was E2V1TM4. Basic movement as assessed by the Functional Status Score for ICU (FSS-ICU) and Barthel Index (BI), was 3 and 0 points, respectively. On D-40, wheelchair use commenced. He began standing with a long leg orthosis on D-50, and began walking on D-53.On D-67, the patient transferred to a convalescent hospital. His GCS was E4V4M6. Generalized cognitive decline and motor paralysis were noted. The right upper limb, hand, and lower limb were assessed as Brunnstrom recovery stage IV, V, and V, respectively. The patient's grip strength was 11.9 kg [right] and 18.3 kg [left]. His knee extensor strength was 0.13 kgf/kg [right] and 0.19 kgf/kg [left]. The FSS-ICU, walking speed, and BI were 21 points, 0.17 m/sec, and 40 points, respectively. The patient was discharged on D-240.Discussion：The Early Mobilization and Rehabilitation Expert Consensus reports that early mobilization and active exercise can improve ADL at discharge. Our patient was weaned from VV-ECMO as soon as possible and practiced standing and walking with a long leg orthosis, resulting in a better outcome.

Difference of clinical characteristics and prognosis of COVID-19 complicated with or without pneumoconiosis in hospitalized patients / 环境与职业医学

Background The novel coronavirus infection is widespread in the world, resulting in more pneumoconiosis patients complicated with coronavirus disease 2019 (COVID-19). Objective To understand the clinical characteristics and prognosis of hospitalized COVID-19 patients complicated with or without pneumoconiosis. Methods A total of 36 COVID-19 patients admitted to the Shandong Provincial Occupational Disease Hospital from 10 December to 31 December 2022 were selected, including 21 cases in the complication group (pneumoconiosis complicated with COVID-19) and 15 cases in the COVID-19 group without pneumoconiosis. Symptoms, signs, laboratory test results(e.g. routine blood test), imaging findings, treatment plans and prognosis of the two groups were observed and compared. Results Regarding symptoms and signs in the complication group and the COVID-19 group, the proportions of dyspnea (57.14% vs 0.00%), lung wheezing (28.57% vs 0.00%), wet rales (76.19% vs 33.30%), and fever (61.90% vs 93.33%) were significantly different (P<0.05). Compared with the COVID-19 group, the level of D-dimer in the complication group was significantly increased [2.340 (1.0, 6.5) mg·L−1 vs 0.250 (0.2, 0.4) mg·L−1] (P<0.01), the serum sodium level was decreased [(138.10±2.68) mmol·L−1 vs (140.47±2.27) mmol·L−1] (P<0.05). In terms of drug treatment and prognosis, there were statistically significant differences in the proportion of antiviral drugs (19.00% vs 80.00%), glucocorticoids (38.10% vs 80.00%), and anticoagulants (28.60% vs 0.00%) between the complication group and the COVID-19 group (P<0.05). Compared with the COVID-19 group, the cure rate of the complication group (90.50% vs 100.00%) showed no statistical difference. However, there were 2 deaths in the complication group. Conclusion Patients with pneumoconiosis complicated with COVID-19 have less fever and more dyspnea, wheezing, and wet rales. The increase of plasma D-dimer is a potential predictor in patients with pneumoconiosis complicated with COVID-19.

Analysis of clinical characteristics and risk factors for adverse outcomes in type 2 diabetic mellitus patients with COVID-19 / 中华临床营养杂志

Objective:The purpose of this study is to explore the clinical characteristics of Coronavirus Disease 2019 (COVID-19) in patients with type 2 diabetes mellitus (T2DM), and analyze the risk factors for adverse outcomes.Methods:2 052 patients diagnosed with COVID-19 who were hospitalized in Shanxi Bethune Hospital between December 1, 2022 and March 20, 2023 were included. They were divided into diabetes group ( n=70) and non-diabetes group ( n=1 982) according to the presence or absence of comorbid T2DM. The two groups were matched at 1:1 via propensity score matching. Clinical characteristics and laboratory examination results of the two groups were compared. According to the outcomes during hospitalization, the two groups were further divided into two subgroups respectively. Univariate analysis and subsequent binary Logistic regression was used to analyze the risk factors of adverse outcomes in patients with COVID-19 and type 2 diabetes. Results:After the propensity score matching, the most common comorbid condition in diabetes group and non-diabetes group was hypertension. The proportion of patients with severe or critical disease in diabetes group was higher compared with non-diabetes group. The levels of hemoglobin A1c (HbA1c), fasting blood glucose (FBG), blood urea, IL-4, IL-6, IL-10, IFN-γ and TNF-α were significantly higher in the diabetes group ( P<0.05). Logistic regression analysis within the diabetes group showed that hypertension ( OR=3.640, 95% CI: 3.156 to 4.290), FBG>11 mmol/L ( OR=3.283, 95% CI: 1.416 to 7.611), HbA1c>10% ( OR=2.718, 95% CI: 1.024 to 7.213) were independent risk factors for adverse outcomes in patients with COVID-19 and type 2 diabetes(all P<0.05). Conclusions:Compared with the non-diabetes group, patients with COVID-19 and T2DM have worse inflammatory response and higher levels of inflammatory cytokines. The elevated levels of FBG and HbA1c are related to the adverse outcome in patients with COVID-19 and T2DM.

Multisystem inflammatory syndrome in children related with COVID-19 infection / 中国免疫学杂志

Multisystem inflammatory syndrome in children is a disease related with severe acute respiratory syndrome corona-virus 2 infection,which can involve multiple system damage.Most cases included features of shock,cardiac dysfunction,gastrointestinal symptoms,significantly elevated markers of inflammation and cardiac damage,and positive test results for SARS-CoV-2 by serology.Although its clinical features overlap with Kawasaki disease,it is more likely to occur in older children and adolescents,and most of them need to be treated with intensive care and a variety of immunomodulators.At present,the pathogenesis and long-term prognosis of the disease need to be further studied.

Enhancing understanding of SARS-CoV-2 infection among individuals with Down syndrome: An integrative review

ABSTRACT BACKGROUND: Down syndrome (DS) is a non-rare genetic condition that affects approximately 1 in every 800 live births worldwide. Further, it is associated with comorbidities, anatomical alterations of the respiratory tract, and immunological dysfunctions that make individuals more susceptible to respiratory infections. OBJECTIVE: To systematize the current scientific knowledge about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among individuals with DS. DESIGN AND SETTING: This integrative review was conducted at the Universidade Federal de São Carlos, São Paulo, Brazil. METHODS: This review was conducted in the following databases: the Virtual Health Library (Biblioteca Virtual em Saúde, BVS), PubMed, and Web of Science, using MeSH descriptors. The search included English or Portuguese studies published between January 1, 2020, and October 14, 2022. RESULTS: A total of 55 articles from 24 countries were selected, comprising 21 case-control or cohort studies, 23 case reports or series, and 11 narrative reviews or opinion studies. The articles were grouped into five categories: previous comorbidities, coronavirus disease 2019 (COVID-19) clinical features and evolution, cytokine storm and interleukins, living in institutions as a risk factor, and behavioral actions as a protective factor against SARS-CoV-2 infection. CONCLUSION: Individuals with DS are more susceptible to COVID-19 infection due to variables such as previous comorbidities, immunological factors, and their habitable environments. These aspects confer a higher risk of infection and an unfavorable clinical course. The precise pathways involved in the pathophysiology of COVID-19 in individuals with DS are not clear, thus requiring further studies. SYSTEMATIC REVIEW REGISTRATION: The Open Science Framework registered the research protocol (https://osf.io/jyb97/).

COVID-19 in Children with West Syndrome: An Ambispective Study

Objectives To study the course of West syndrome (WS) and coronavirus disease-19 (COVID-19) in children with WS who contracted SARS-CoV-2 infection. Methods This ambispective study was conducted at a tertiary-care center in North India between December 2020 and August 2021 after approval from the Institute Ethics Committee. Five children with WS, positive for COVID-19 based on RT-PCR, fulflled the inclusion criteria. Results One child with COVID-19 during the frst wave was retrospectively included while four children (of the 70 children screened) were prospectively enrolled. The median age at onset of epileptic spasms was 7 mo (2 boys), and that at presentation with COVID-19 was 18.5 mo. Three had underlying acquired structural etiology. Three were in remission following standard therapy, while two had ongoing spasms at the time of COVID-19 illness. During the illness, two of those in remission continued to be in remission while one child had a relapse. The children with ongoing epileptic spasms had variable course [one had persistent spasms and other had transient cessation lasting 3 wk from day 2 of COVID-19 illness, but electroencephalography (on day 8 of COVID-19 illness) continued to show hypsarrhythmia]. Fever was the most typical symptom (and sometimes the only symptom) of COVID-19, with a duration ranging from 1–8 d. Two children had moderate COVID-19 illness requiring hospitalization, while the rest had a mild illness. All the afected children had complete recovery from COVID-19. Conclusion The severity of COVID-19 illness in children with WS is often mild, while the subsequent course of WS is variable.

Pleural empyema after COVID-19: A delayed presentation

Globally, the number of coronavirus disease-2019 (COVID-19) cases and deaths shows a declining trend since a peak in January 2022. For now, the pandemic phase looks to be ended, until a severe new variant may trigger another wave. At present, in India, small pockets of COVID-19 cases and post-COVID complications are still being reported. Therefore, physicians should remain vigilant about the atypical presentations and potential delayed or long-term complications of SARS-CoV-2 infection, even in individuals who had a mild COVID-19 infection. Here, we present the case of a 52-year-old male patient with a history of hypertension, who is a non-smoker and developed culture-negative pleural empyema 7 months after a mild COVID-19 infection. The patient was successfully treated with antibiotics and early video-assisted thoracoscopic surgery
