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/).

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.

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

Awareness, perceptions, and attitude towards Coronavirus disease 2019 vaccine among pregnant women in India: A cross-sectional study

Introduction: The present study was conducted to explore the awareness and perception of the coronavirus disease 2019 (COVID-19) vaccine among pregnant women. Material and Methods: A descriptive cross-sectional study was conducted from September 01, 2021, to September 28, 2021, among 301 pregnant women aged 18–35 years at antenatal care outpatient department in a tertiary care hospital of Western Maharashtra. Results: On assessing the knowledge and awareness score, the mean score (± standard deviation) was 7.83 ± 1.2 out of 16. A total of 176 (58.5%) had good scores(?8). There was no statistically significant association between knowledge and awareness scores and the level of education, type of residence, and age or with weeks of gestation. Although the overall awareness of study participants was satisfactory, 177 (58.8%) felt that COVID-19 vaccines should be avoided during the first trimester. Interestingly, 45 (15.3%) felt that vaccines should not be given during menstruation. There were misconceptions about perceived contraindication, with 81(26.9%), 50(16.6%) and 43(14.4%) responding that diabetes, hypertension and heart disease are contradicts respectively. Interestingly, a total of 52 (17.3%) responded as likely when enquired whether the present vaccine can cause infertility. Similarly, about 62% of study participants felt that the vaccine might alter the DNA. Conclusion: The present study revealed good overall knowledge and awareness about the COVID-19 vaccine among pregnant with certain misconceptions. The findings suggest that immediate health education programs, risk communication, and correct information should be disseminated by respective health authorities.

Comparative study of the clinicoepidemiological profile of COVID-19 patients of first wave and second wave admitted in a tertiary care teaching hospital in Nadiad, Gujarat, India

Background: According to other studies, second wave was different as compared to the first wave in clinical outcomes and laboratory parameters. Aims and Objectives: We aimed to compare the clinicoepidemiological features and their effect on mortality in coronavirus disease-2019 (COVID-19) patients of first wave versus second wave. Materials and Methods: We carried out cross-sectional, observational, and retrospective study among two groups of COVID-19 patients of first and second wave. Each group contains a 135 patients of COVID-19 admitted at our hospital. We analyzed the demographic profile, clinical features, comorbidities, and inflammatory markers. Results: In our study, majority patients were male (67%). Majority number of the patients were between 18 and 60 years of age in both the groups. Presenting complaint of shortness of breath was significantly higher in second wave and sore throat was significantly higher in first wave. SpO2 on admission was significantly lower in second wave (93% vs. 98%). Median value of C-reactive protein (6.865 vs. 2.805), neutrophil-leucocyte ratio (4.647 vs. 2.917), and D-dimer (679.5 vs. 450) were significantly higher in second wave. Second wave had significantly higher mortality as compared to first wave (18.5% vs. 4.4%). However, level of D-dimer was found significantly higher in patients who died during first wave (6820 vs. 848). Higher mortality was seen in male patients of second wave. Conclusion: Overall higher mortality was seen during the second wave which was supported by increased in the inflammatory markers. Delta variant, late admission, increased demand of oxygen support, and intensive care unit beds may have led to higher mortality.

A review of venous thromboembolism in India

Venous thromboembolism (VTE), which entails the formation of a thrombus (blood clot) in a vein, has a significant disease burden worldwide. While VTE has traditionally been considered to predominantly affect Caucasian populations, recent studies have indicated a gradual shift in the disease burden towards Asian populations, with added significance of it being a key driver of post-operative mortality. It is imperative to develop a sound understanding of the various factors that affect VTE in stratified local populations. However, there is a glaring paucity of quality data on VTE and its ramifications among Indians - both in terms of quality of life and cost of healthcare. This review aims to throw light on the disease burden, epidemiology, risk factors, environmental factors, food and nutrition that plays a key role in VTE. We also explored the association of VTE with coronavirus disease 2019 to grasp the interplay between the two most significant public health crises of our time. It is vital to place a special emphasis on future research on VTE in India to plug the gaps, which exist in our current knowledge of the disease, particularly with respect to Indian population

Bilateral acute depigmentation of the iris determined in two cases after COVID-19 infection

Bilateral acute depigmentation of the iris (BADI) is a rare disease characterized by iris atrophy. Although it can be self-limiting, it is sometimes progressive and can lead to glaucoma and severe vision loss. Two female patients were admitted to our clinic because of a change in iris color following coronavirus disease 2019 (COVID-19) infection. After the exclusion of other etiologies in the eye examination, BADI was diagnosed in both cases. Thus, it was shown that COVID-19 may also be involved in the etiology of BADI.

Lipschütz acute vulvar ulcer related to COVID-19 vaccination: First case report in South America / Úlcera vulvar aguda de Lipschütz relacionada con la vacunación por COVID-19: primer caso notificado en Sudamérica

Lipschütz ulcer is a non-sexually transmitted genital lesion of unknown etiology, which presents as a painful vulvar ulcer. Lipschütz ulcers have been described in most continents. This is the first case reported in Peru and South America. We present the case of a 33-year-old female patient with a Lipschütz ulcer after being vaccinated with the second dose of the AstraZeneca COVID-19 vaccine. She reported having had only one sexual partner in her lifetime. Laboratory results were negative for herpes simplex 2, Cytomegalovirus, Toxoplasma gondii, Epstein-Barr virus, and syphilis. The patient received symptomatic treatment. Ten days after the onset, the patient was significantly better during follow-up. This case report displays a potential adverse effect of the AstraZeneca COVID-19 vaccine as a Lipschütz ulcer triggered by the host humoral immune response. However, further research is needed to establish the causal relationship between these two.

La úlcera de Lipschütz es una lesión genital no transmitidas por vía sexual de etiología desconocida, se presenta como una úlcera vulvar muy dolorosa. Las úlceras de Lipschütz se han descrito en la mayoría de los continentes. Este es el primer caso que se reporta en Perú y Sudamérica. En este reporte de caso se presentauna paciente de 33 años con una úlcera de Lipschütz luego de haber sido vacunada con la segunda dosis de la vacuna AstraZeneca COVID-19. Refirió haber tenido una sola pareja sexual a lo largo de su vida. Los resultados de laboratorio fueron negativos para herpes simplex 2, Citomegalovirus, Toxoplasma gondii, virus de Epstein-Barr y sífilis. La paciente recibió tratamiento sintomático. Diez días después, durante el seguimiento, la paciente estaba significativamente mejor. Este reporte de caso expone un potencial efecto adverso de la vacuna AstraZeneca COVID-19, en forma de úlcera de Lipschütz, desencadenado por la respuesta inmune humoral del huésped. Sin embargo, es necesario realizar más investigación para establecer la relación causal entre ambos.

Pulmonary embolism in an adolescent with COVID-19 pneumonia / Tromboembolismo pulmonar en un adolescente con neumonía COVID-19

Abstract Background: Pulmonary embolism (PE) is a complication reported in the adult population with coronavirus disease 2019 (COVID-19); however, its documentation in the pediatric population is limiteda. Case report: We report the case of a 15-year-old male with obesity and Down syndrome who was admitted for severe COVID-19 pneumonia. On day 7 of admission, he presented with chest pain, hemoptysis, respiratory distress, and marked elevation of D-dimer. Pulmonary CT angiography found an extensive thrombus in the right lower lobar artery. He received treatment with enoxaparin and rivaroxaban and had a favorable clinical outcome. In the tomographic control 1 month after treatment, thrombus was not evidenced and was successfully resolved. Conclusions: There are few reports of PE in children with COVID-19. Prompt diagnosis and early anticoagulant treatment are important to avoid life-threatening complications.

Vascular endothelial growth factor gene insertion/deletion polymorphism is associated with Vitamin D level in Turkish patients with coronavirus disease 2019

SUMMARY OBJECTIVE: Coronavirus disease 2019 emerges as a disease caused by severe acute respiratory syndrome coronavirus 2. It is a systemic disease associated with vascular inflammation and endothelial damage. In this study, we aimed to investigate whether vascular endothelial growth factor gene insertion/deletion polymorphism is associated with coronavirus disease 2019 in the Turkish population. METHODS: The study included 179 participants (79 patients with coronavirus disease 2019 and 100 controls). DNA isolation was made from peripheral blood, and then the polymerase chain reaction analysis was performed. RESULTS: When we analyze vascular endothelial growth factor gene insertion/deletion polymorphism in the study group, we found that the DD genotype and D allele were found to be statistically significantly different when compared to coronavirus disease 2019 patients with high vitamin D value (p=0.005 for DD genotype and p=0.006 for D allele) in the control group. In this high-level control group, when we analyze II+ID genotype versus DD, a statistically significant difference was also detected (p=0.007). CONCLUSION: As a result of the study, we found that DD genotype and D allele were associated with vitamin D level in Turkish patients with coronavirus disease 2019.

After action review of the COVID-19 pandemic response in North West province, South Africa

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused coronavirus disease 2019 (COVID-19) pandemic with major disruptions globally. Northwest Province Department of Health (NWDoH) in South Africa set up comprehensive epidemiological emergency response plans for preventing, finding, containing and stopping the spread of COVID-19 in accordance with the National Disaster Management Act. Objectives: This After-Action Report (AAR) describes the provincial response to the pandemic from September 2020 to October 2022. Method: The AAR was conducted using the World Health Organization AAR methodology. Focus groups discussed five items: coordination, leadership and governance; epidemiology, surveillance and laboratory; case management and continuity of essential services; risk communication and community engagement and COVID-19 vaccination. Results: The timely establishment and activation of provincial intergovernmental and intersectoral coordinating structures led to effective coordination, resource mobilisation, leadership, decision-making and intervention. The effective communication in the department and other stakeholders resulted in improved surveillance data quality, timelier response and increased ownership of data. Dissemination, training and implementation of case management protocols ensured standardised case management. The multi-channel information dissemination targeting different audiences empowered people with real-time knowledge on the infection and encouraged health-seeking behaviours. Conclusion: The AAR demonstrated the importance of coordinated epidemiological, laboratory and communication response that requires significant public health reserve capacity in peacetime for rapid expansion in an emergency. Contribution: This review contributes to the body of knowledge emerging from the COVID-19 pandemic and provides guidance on enhanced public health response to future emergencies.

Acute and subacute oral toxicity characterization and safety assessment of COVID organics® (Madagascar's Anti­COVID Herbal Tea) in animal models

Introduction: Coronavirus disease 2019 (COVID 19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. No drug has been generally approved as safe and effective for the treatment of COVID 19. Several therapeutic agents such as COVID Organics® (CVO) have been explored as treatment options. CVO is an herbal tea composed of 62% of Artemisia annua and 38% of other plants. There is presently no existing scientific report and data on the safety and efficacy of CVO herbal drug. Thus, acute and subacute toxicity studies were undertaken to evaluate the safety and toxicity of CVO on short and long term usage in animal models. Materials and Methods: Phytochemical and nutritional compositions of CVO were determined using standard methods. Acute oral toxicity was investigated using female Swiss albino mice (three per group). While subacute oral toxicity was done using female and male Swiss albino rats (five per group). The animals were administered 2000 mg/kg, 5000 mg/kg, therapeutic dose; 5500 mg/kg and supratherapeutic dose; 11,000 mg/kg of CVO herbal product. The control group received water ad libitum. The oral toxicity studies were done in accordance with Organization for Economic Corporation and Development guidelines. The experimental protocol was approved by the Institutional Animal Care and Use Committee, Nigerian Institute of Medical Research (Ethics No. IRB/17/043). Results: CVO is rich in antioxidants: flavonoids(10.3%), tannins(29.1%), and phenolics(434.4 mg). It contains proteins (33.8%), carbohydrates (34.5%), fat (6.8%), and fiber (0.5%). In the acute toxicity study, no mortality was recorded in all the treated and untreated groups. The lethal dose of CVO is >5000 mg/kg body weight. The hematological, biochemical, lipid profile, and histologic parameters were all normal at therapeutic doses when compared to the control group. Conclusion: The acute and subacute oral toxicity studies revealed that CVO is not toxic. The specific organ toxicity evaluations also indicated that CVO has no toxic effects on blood parameters and vital organs structure and function at therapeutic dose. Thus, CVO is safe for short and long term usage. We recommend that CVO should be subjected to efficacy studies to investigate whether it is effective for COVID 19 treatment as claimed by the manufacturer.

Analysis on the influencing factors for re-positive nucleic acid test result in discharged COVID-19 patients in Chengdu / 中国胸心血管外科临床杂志

@#Objective    To analyze the influencing factors for re-positive nucleic acid test in discharged corona-virus disease 2019 (COVID-19) patients in Chengdu, Sichuan Province, and to provide data support for the epidemics prevention and control. Methods    The clinical data of 660 discharged COVID-19 patients from January 23, 2020 to February 28, 2021 in our center were retrospectively analyzed. The patients were divided into two groups according to the reexamination of virus nucleic acid, including a negative group [549 patients, including 428 males and 121 females with a median age of 33.0 (28.0, 48.0) years] and a positive group [111 patients, including 76 males and 35 females with a median age of 39.0 (28.0, 51.0) years]. The clinical data of the two groups were compared. Results     The re-positive rate of the discharged patients was 16.82%. Univariate analysis showed that the re-positive rate of females was higher than that of males (χ2=4.608, P=0.032). The re-positive rate of confirmed patients was higher than that of asymptomatic infected patients (χ2=8.140, P=0.004). The re-positive rate of domestic patients was higher than that of imported patients (χ2=9.178, P=0.002). The counts of CD3+ (P=0.038), CD4+ (P=0.048) and CD8+ (P=0.040) T lymphocytes in the negative group were higher than those in the positive group. The binary logistic regression analysis showed that the clinical classification and CD8+ T lymphocyte count were independent risk factors affecting the recurrence of virility. Conclusion    The gender, origin, T lymphocyte subsets count and clinical type are the influencing factors for re-positive result, and clinical type and CD8+ T lymphocyte count are the independent influencing factors for re-positive result. Therefore, improving the immunity of infected patients, as well as early detection and timely treatment are effective means to reduce the re-positive occurrence.

Predictive value of the simplified signs scoring system for the severity and prognosis of patients with COVID-19: A multicenter observational study / 中国胸心血管外科临床杂志

@# Objective    To explore the predictive value of a simplified signs scoring system for the severity and prognosis of patients with coronavirus disease 2019 (COVID-19). Methods     Clinical data of 1 605 confirmed patients with COVID-19 from January to May 2020 in 45 hospitals of Sichuan and Hubei Provinces were retrospectively analyzed. The patients were divided into a mild group (n=1 150, 508 males, average age of 51.32±16.26 years) and a severe group (n=455, 248 males, average age of 57.63±16.16 years). Results    Age, male proportion, respiratory rate, systolic blood pressure and mean arterial pressure in the severe group were higher than those in the mild group (P<0.05). Peripheral oxygen saturation (SpO2) and Glasgow coma scale (GCS) were lower than those in the mild group (P<0.05). Multivariate logistic regression analysis showed that age, respiratory rate, SpO2, and GCS were independent risk factors for severe patients with COVID-19. Based on the above indicators, the receiver operating characteristic (ROC) curve analysis showed that the area under the curve of the simplified signs scoring system for predicting severe patients was 0.822, which was higher than that of the quick sequential organ failure assessment (qSOFA) score and modified early warning score (MEWS, 0.629 and 0.631, P<0.001). The ROC analysis showed that the area under the curve of the simplified signs scoring system for predicting death was 0.796, higher than that of qSOFA score and MEWS score (0.710 and 0.706, P<0.001). Conclusion    Age, respiratory rate, SpO2 and GCS are independent risk factors for severe patients with COVID-19. The simplified signs scoring system based on these four indicators may be used to predict patient's risk of severe illness or early death.

Coronavirus disease 2019 in kidney transplant recipients: a systematic review and meta-analysis

INTRODUCTION@#The clinical presentation and outcomes of coronavirus disease 2019 (COVID-19) in kidney transplant recipients (KTRs) have not been well studied.@*METHODS@#We performed a meta-analysis to examine the presenting features, outcomes and the effect of treatment on outcomes of KTRs with COVID-19. Database search was performed up to 5 September 2020 through PubMed, Embase, Web of Science, Scopus and CENTRAL.@*RESULTS@#Overall, 23 studies (1,373 patients) were included in the review and meta-analysis. The most common presenting symptoms included fever (74.0%, 95% confidence interval [CI] 65.3-81.1), cough (63.3%, 95% CI 56.5-69.6) and dyspnoea (47.5%, 95% CI 39.6-55.6). Pooled rates of mortality and critical illness were 21.1% (95% CI 15.3-28.4) and 27.7% (95% CI 21.5-34.8), respectively. Acute kidney injury occurred in 38.9% (95% CI 30.6-48.1) and dialysis was required in 12.4% (95% CI 8.3-18.0) of the cases.@*CONCLUSION@#Kidney transplant recipients with COVID-19 have a similar clinical presentation as the general population, but they have higher morbidity and mortality. It is uncertain whether high-dose corticosteroid or hydroxychloroquine reduces the risks of mortality in KTRs with COVID-19.

Uptake and impact of COVID-19 vaccination among HIV key populations: a cohort study from Tamil Nadu, India / Journal of Rural Medicine

Objective: Human Immunodeficiency Virus (HIV) Key Populations (KPs) include Female Sex Workers (FSWs), men who have sex with men (MSM), transgender (TG), and transsexual (TS) persons. This study assessed coronavirus disease 2019 (COVID-19) vaccine uptake among KPs for HIV in India, adverse events following immunization (AEFI), and breakthrough infections among the vaccinated.Materials and Methods: This retrospective cohort study was conducted among 421 KPs enrolled in 41 Targeted Intervention (TI) clusters in 31 districts of the Tamil Nadu State Acquired Immunodeficiency Syndrome (AIDS) Control Society (TANSACS), India, from June to September 2022. A semi-structured, bilingual (English and Tamil), interviewer-administered questionnaire was used to collect data on socio-demographic characteristics, vaccination status, AEFIs, and breakthrough infections among the KPs under the TIs.Results: Among the KPs, 45.4% were FSWs, 37.1% were MSM, 16.2% were TG, and 1.4% were TS persons. Among them, 4.3% had HIV, and 2.9% had syphilis or other sexually transmitted infections (STIs). The COVID-19 vaccine uptake rate was 96%. Among the KPs, TG/TS persons had the highest vaccine uptake (98.6%), followed by FSWs (96.3%) and MSM (94.2%). AEFIs were reported by 85.4% of the participants. HIV positive status was significantly associated with the incidence of AEFI. The breakthrough infection rate was 5.4% among the vaccinated participants.Conclusion: The COVID-19 vaccine uptake among HIV KPs was high in Tamil Nadu. AEFIs and breakthrough infections among COVID-19 vaccinated HIV KPs may be low, with mild AEFIs.
