RESUMEN

ABSTRACT Unvaccinated identical twins developed bilateral anterior uveitis soon after the onset of coronavirus disease 2019 symptoms. During follow-up, both patients developed choroiditis, and one twine developed posterior scleritis and serous retinal detachment. Prompt treatment with oral prednisone ameliorated the lesions, and no recurrence was observed at the 18-month follow-up. Choroiditis may rarely be associated with severe acute respiratory syndrome coronavirus 2 infection, and it responds well to corticosteroid therapy. Although the exact mechanism is unknown, we hypothesize that the virus may act as an immunological trigger for choroiditis.

RESUMEN

A síndrome respiratória aguda grave (SRAG) é caracterizada por sintomas de febre alta, tosse e dispneia, e, na maioria dos casos, relacionada a uma quantidade reduzida de agentes infecciosos. O objetivo foi avaliar a prevalência dos vírus respiratórios Influenza A (FluA), vírus sincicial respiratório (RSV) e do novo coronavírus (SARS-CoV-2) em pacientes com internação hospitalar por SRAG. Estudo transversal, com pacientes em internação hospitalar com SRAG entre novembro de 2021 e maio de 2022. Dados sociodemográficos e clínicos e amostras da nasofaringe foram coletados/as, as quais foram submetidas à extração de RNA e testadas quanto à positividade para Influenza A, RSV e SARS-CoV-2 por meio da técnica de PCR em tempo real pelo método SYBR Green. Foram incluídos 42 pacientes, sendo 59,5% do sexo feminino, 57,1% idosos, 54,8% com ensino fundamental. A maior parte dos pacientes reportou hábito tabagista prévio ou atual (54,8%), não etilista (73,8%) e 83,3% deles apresentavam alguma comorbidade, sendo hipertensão arterial sistêmica e diabetes mellitus tipo 2 as mais prevalentes. Um total de 10,5% dos pacientes testou positivo para FluA, nenhuma amostra positiva para RSV e 76,3% positivos para SARS-CoV-2. Na população estudada, SRAG com agravo hospitalar foi observado em maior proporção, em mulheres, idosos e pessoas com comorbidades, embora sem significância estatística, sendo o novo coronavírus o agente etiológico mais relacionado, o que evidencia a patogenicidade desse agente e suas consequências ainda são evidentes após quase 2 anos de período pandêmico.


Severe acute respiratory syndrome (SARS) is characterized by symptoms of high fever, cough and dyspnea, and is in most cases related to a reduced amount of infectious agents. The objective was to assess the prevalence of respiratory viruses Influenza A (FluA), respiratory syncytial virus (RSV) and the new coronavirus (SARS-CoV-2) in patients hospitalized for SARS. Cross-sectional study, with patients hospitalized with SARS between November 2021 and May 2022. Sociodemographic and clinical data and nasopharyngeal samples were collected, which were subjected to RNA extraction and tested for positivity for Influenza A, RSV and SARS-CoV-2 using the real-time PCR technique using the SYBR Green method. 42 patients were included, 59.5% female, 57.1% elderly, 54.8% with primary education. Most patients reported previous or current smoking habits (54.8%), non-drinkers (73.8) and 83.3% of them had some comorbidity, with systemic arterial hypertension and type 2 diabetes mellitus being the most prevalent. A total of 10.5% of patients tested positive for FluA, no samples positive for RSV, and 76.3% positive for SARS-CoV-2. In the studied population, SARS with hospital injury was observed more frequently in women and the elderly, with associated comorbidities, with the new coronavirus being the most related etiological agent, which shows, although not statistically significant, that the pathogenicity of this agent and its consequences are still evident after almost 2 years of period pandemic.

RESUMEN

O presente estudo buscou analisar a prevalência e os fatores associados à necessidade de cuidados intensivos por adultos hospitalizados, devido à Covid-19, no estado do Paraná. Para atingir o objetivo proposto, realizou-se um estudo transversal com notificações compulsórias da Síndrome Respiratória Aguda Grave, associada à Covid-19. Na análise, foram aplicados modelos de regressão de Poisson em modelos univariados e multivariados, com associações estimadas por Razão de Prevalência. No período analisado, foram registradas 61.213 hospitalizações por Covid-19 no estado. Os pacientes possuíam, maioritariamente, entre 45 e 59 anos, sexo masculino, raça branca e sem fatores de risco/comorbidade. Os principais achados permitiram inferir que a gravidade e necessidade de cuidados intensivos foi associada à idade, sexo raça/cor, uso de imunizante contra gripe, diagnóstico de comorbidades prévias, ter apresentado sintomas moderados/graves e local de residência diferente do município de hospitalização. Ainda, os piores desfechos da Covid-19 foram influenciados por fatores sociodemográficos, clínicos e epidemiológicos, os quais estiveram relacionados à gravidade da doença e necessidade de cuidados intensivos. Assim sendo, identificou-se uma elevada prevalência de hospitalização em Unidades de Terapia Intensiva, diante características intrínsecas e extrínsecas aos indivíduos acometidos pela doença.


This study sought to analyze the prevalence and factors associated with the need for intensive care by adults hospitalized due to Covid-19 in the state of Paraná. To achieve the proposed objective, a cross-sectional study was carried out with compulsory notifications of Severe Acute Respiratory Syndrome associated with Covid-19. In the analysis, Poisson regression models were applied in univariate and multivariate models, with associations estimated by Prevalence Ratio. In the period analyzed, 61,213 hospitalizations due to Covid-19 were recorded in the state. The majority of patients were between 45 and 59 years old, male, white and had no risk factors/comorbidities. The main findings allowed us to infer that the severity and need for intensive care was associated with age, gender, race/color, use of influenza immunization, diagnosis of previous comorbidities, having presented moderate/severe symptoms and place of residence other than the municipality of hospitalization. Furthermore, the worst Covid-19 outcomes were influenced by sociodemographic, clinical and epidemiological factors, which were related to the severity of the disease and the need for intensive care. Therefore, a high prevalence of hospitalization in Intensive Care Units was identified, given the intrinsic and extrinsic characteristics of individuals affected by the disease.


Este estudio buscó analizar la prevalencia y los factores asociados a la necesidad de cuidados intensivos por adultos hospitalizados debido al Covid-19 en el estado de Paraná. Para alcanzar el objetivo propuesto, se realizó un estudio transversal con notificaciones obligatorias de Síndrome Respiratorio Agudo Severo asociado a Covid-19. Se aplicaron modelos de regresión de Poisson en modelos univariados y multivariados, con asociaciones estimadas por Razón de Prevalencia. En el periodo analizado, se registraron 61.213 hospitalizaciones por Covid-19 en el estado. La mayoría de los pacientes tenían entre 45 y 59 años, eran varones, de raza blanca y no presentaban factores de riesgo/comorbilidades. Los principales hallazgos permitieron inferir que la gravedad y la necesidad de cuidados intensivos se asociaron a la edad, el sexo, la raza/color, el uso de la vacuna antigripal, el diagnóstico de comorbilidades previas, haber presentado síntomas moderados/graves y el lugar de residencia distinto al municipio de hospitalización. Además, los peores resultados del Covid-19 se vieron influidos por factores sociodemográficos, clínicos y epidemiológicos, que estaban relacionados con la gravedad de la enfermedad y la necesidad de cuidados intensivos. Por tanto, se identificó una elevada prevalencia de hospitalización en Unidades de Cuidados Intensivos, dadas las características intrínsecas y extrínsecas de los individuos afectados por la enfermedad.

RESUMEN

Background: Coronavirus disease 2019 (COVID-19) novel severe acute respiratory syndrome affected the world population with an infectious condition for which therapeutic forms are limited and vascular sequelae are major challenges. Pregnant women are physiologically immunocompromised and can be more affected by the pandemic than the general population. Extra precaution measures against COVID-19 during and after the outbreak are essential to ensure the safety of the newborn. The aim of the present study was to report the cesarean birth of a female child with Klippel-Trenaunay of a mother currently infected by COVID-19. Case Description: A newborn of a 21-year-old mother with COVID-19 in the final stage of the disease was born through a cesarean section at full term. The physical examination at birth revealed substantial edema of the left lower limb associated with port-wine stains on the limb and left torso. The ultrasound revealed venous-lymphatic malformation affecting the entire left lower limb, suprapubic region and ipsilateral abdominal region. Two evaluations for COVID-19 were performed and both were negative. Infants of mothers with active COVID-19 infection during the birth period have a low probability of being positive for the disease, but precautions should be taken. Conclusions: The association with malformations, such as the rare Klippel-Trenaunay syndrome (KTS), constitutes another challenge regarding the diagnosis and proper conduct to be taken with these children.

RESUMEN

The multiplex molecular diagnostic assays described for severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), influenza A (IAV) and B (IBV) viruses have been mainly based on real-time reaction, which limits their access to many laboratories or diagnostic institutions. To contribute to available strategies and expand access to differential diagnosis, we describe an end-point multiplex RT-PCR targeting SARS-CoV-2, IAV and IBV with simultaneous endogenous control amplification. Initially, we looked for well-established primers sets for SARS-CoV-2, IAV, IBV and RNAse P whose amplicons could be distinguished on agarose gel. The multiplex assay was then standardized by optimizing the reaction mix and cycle conditions. The limit of detection (LoD) was determined using titrated viruses (for SARS-CoV-2 and IAV) and by dilution from a pool of IBV-positive samples. The diagnostic performance of the multiplex was evaluated by testing samples with different RNAse P and viral loads, previously identified as positive or negative for the target viruses. The amplicons of IAV (146 bp), SARS-CoV-2 (113 bp), IBV (103 bp) and RNAse P (65 bp) were adequately distinguished in our multiplex. The LoD for SARS-CoV-2, IAV and IBV was 0.02 TCID50/ml, 0.07 TCID50/ml and 10-3 from a pool of positive samples, respectively. All samples positive for SARS-CoV-2 (n=70, Ct 17.2-36.9), IAV (n=53, Ct 14-34.9) and IBV (n=12, Ct 23.9-31.9) remained positive in our multiplex assay. RNAse P from negative samples (n=40, Ct 25.2-30.2) was also amplified in the multiplex. Overall, our assay is a timely and alternative tool for detecting SARS-CoV-2 and influenza viruses in laboratories with limited access to supplies/equipment.

RESUMEN

Numerous commercial tests for the serological diagnosis of COVID-19 have been produced in recent years. However, it is important to note that these tests exhibit significant variability in their sensitivity, specificity, and accuracy of results. Therefore, the objective of this study was to utilize bioinformatics tools to map SARS-CoV-2 peptides, with the goal of developing a new serological diagnostic test for COVID-19. Two peptides from the S protein and one from the N protein were selected and characterized in silico, chemically synthesized, and used as a serological diagnostic tool to detect IgM, IgG, and IgA anti-SARS-CoV-2 antibodies through the ELISA technique, confirmed as positive and negative samples by RT-qPCR or serology by ELISA. The results showed a sensitivity, specificity, Positive Predictive Value and Negative Predictive Value of 100% (p < 00001, 95% CI) for the proposed test. Although preliminary, this study brings proof-of-concept results that are consistent with the high-performance rates of the ELISA test when compared to other well-established methods for diagnosing COVID-19.

RESUMEN

We conducted a multicountry retrospective study using data from COVID-19 national surveillance databases to analyze clinical profiles, hospitalization rates, intensive care unit (ICU) admissions, utilization of ventilatory support, and mortality rates in five Latin American countries in the context of COVID-19 vaccination implementation. We analyzed the sociodemographic characteristics, comorbidities, clinical outcomes, and vaccination status of laboratory-confirmed COVID-19 cases from January 2021 to December 2022. We calculated the yearly and quarterly hospitalization rates per 1000 confirmed COVID-19 cases and ICU admissions, use of mechanical ventilators, and mortality rates per 1000 hospitalized cases, with their corresponding 95% confidence interval (CI) of 38,852,831 confirmed COVID-19 cases. Rates of hospitalization, ICU admission, ventilatory support, and death were higher among males than among females (38.2 vs. 32.4, 148.4 vs. 117.7, 282.9 vs. 236.2, and 346.9 vs. 320.1 per 1000, respectively); higher in 2021 than in 2022 (50.7 vs. 19.9, 207.8 vs. 58.2, 441.5 vs. 114.9, and 352.5 vs. 285.2 per 1000, respectively); and in the >50 age group (range: 5.7-18.6, 20.1-71.5, 12.2-67.9, and 353.1-577.4, per 1000) than the <50 age group (range: 2.2-9.3, 5.4-33.2, 41.4-135.8, and 22-243.5 per 1000). Hypertension and diabetes mellitus were the most common comorbidities in Mexico and Colombia. Prevention and treatment strategies for these case profiles could bring benefits from a public health perspective.

RESUMEN

Introduction: The expansion of telehealth during the COVID-19 pandemic may widen digital divides. It is essential to better understand the use of telehealth by the elderly population for the development of equitable telehealth tools. Objectives: This study aimed to describe the socioeconomic, clinical, and functional characteristics of elderly patients who were supported by a COVID-19 telehealth program. It also investigated the characteristics associated with the need for support for teleconsultations, hospitalization, and mortality. Methods: >Elderly patients supported by the TeleCOVID-MG program, between June 2020 and December 2021, in two Brazilian municipalities (Divinópolis and Teófilo Otoni) were included. Data were collected from electronic records and through phone call interviews. Descriptive and multivariable analyses were performed. Results: Among the 237 patients,121 were women (51.1%), mean age was 70.8 years (±8.5), 121 (51.1%) had less than 4 years of formal education, 123 patients (51.9%) had two or more comorbidities, and 68 (29%) reported functional decline in activities of daily life. Age greater than 80 years (odds ratio [OR]:4.68, 95% confidence interval [CI] 1.93-11.37, p = 0.001), lower educational level (OR:3.85, 95% CI 1.8-8.21, p < 0.001), hearing (OR:5.46, 95% CI: 1.24-11.27, p = 0.019), and visual (OR:15.10, 95% CI: 3.21-71.04, p = 0.001) impairments were characteristics associated with the need for support for teleconsultations. The need for support was associated with hospitalization and mortality (OR:5.08, 95% CI: 2.35-10.98, p < 0.001). Conclusion: Older age, lower educational level, and sensory impairments may compromise the effectiveness and the safety of the telehealth assistance to the elderly population. Functional evaluation and frailty screening should be considered part of the telehealth assessment of elderly patients.

RESUMEN

OBJECTIVE: To describe the clinical-laboratory profile and analyze the factors associated with the severity of COVID-19. METHODS: A prospective cohort study involving patients with COVID-19 admitted to a tertiary hospital in Recife, Brazil. All cases were confirmed by RT-PCR and classified according to severity criteria. A descriptive statistical analysis of the population's characteristics was conducted. Risk factors associated with the outcome of the case according to severity were analyzed by calculating the odds ratio (OR) using the general equation estimation (GEE) model. RESULTS: Among the 75 cases included, 64% were female, and 62.7% were aged 65 years or older. The median length of stay was 9 days (6 - 14). Hypertension (65.3%) and Diabetes Mellitus (36%) were the most frequent comorbidities. Severe forms of COVID-19 constituted 41.3% of the sample. The factors associated with severity were a history of asthma (OR=4.58, 95%CI:1.13 - 18.7), report of anorexia (OR=1, 12, 95%CI:1.01-1.24), and laboratory changes that included elevated platelets (OR=1.00, 95% CI:1.00-1.01), elevated D'Dimer (OR=1, 26, 95% CI:1.04-1.52), elevated aspartate aminotransferase (OR=1.00, 95% CI:1.00-1.01), and gamma-glutamyl transferase (OR=1.22, IC95 %:0.98-1.51), hypernatremia (OR=1.31, 95%CI:1.12-1.52), and hyperkalemia (OR=1.21, 95% CI:1.04-1.41). CONCLUSION: Multisystemic involvement with a tendency for thrombophilia, electrolyte disturbances, and hepatic aggression, reflected by laboratory changes, were factors associated with the severity of COVID-19.

RESUMEN

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted health, mental well-being, and societal functioning, particularly for individuals with psychiatric conditions and substance use disorders. Recent evidence highlights a concerning increase in alcohol consumption during the pandemic, with a study spanning 2015-2020 indicating heightened usage, especially among young and middle-aged adults, for relaxation and tension relief. Additionally, addressing challenges exacerbated by the pandemic, another study underscored persistent barriers to healthcare access, resulting in increased alcohol and tobacco use rates and limited healthcare options. These findings shed light on the unique vulnerabilities exposed by the pandemic, emphasizing the need to investigate further its impact on alcohol consumption in diverse non-urban American communities. AIM: To investigate the impact of the COVID-19 pandemic on alcohol abuse using socioeconomic and medical parameters in diverse non-urban community in America. METHODS: Based on a cross-sectional analysis of 416 participants the United States in 2021, the study utilized The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria to categorize alcohol consumption levels. Participants aged 21 years and above were surveyed through an online platform due to COVID-19 challenges. The survey was conducted from January 14 to January 31, 2022, recruiting participants via social media and ensuring anonymity. Informed consent was secured, emphasizing the voluntary nature of participation, and participants could only take the survey once. RESULTS: Out of 416 survey respondents, 396 met eligibility criteria, with 62.9% reporting increased alcohol consumption during COVID-19. Males (68.8%) and ages 21-29 years (34.6%) predominated. Low alcohol consumption decreased by 2.8% (P = 0.237), moderate by 21.4% (P < 0.001), and heavy increased by 14.9% (P < 0.001). Alcohol abuse rose by 6.5% (P = 0.0439), with a 7% increase in self-identified alcohol abusers/alcoholics. Seeking treatment during COVID-19 rose by 6.9%. Easier alcohol access (76.0%) was reported, while 80.7% found it harder to access medical care for alcohol-related issues. These findings highlight the pandemic's impact on alcohol consumption and healthcare access, emphasizing the need for targeted interventions during public health crises. CONCLUSION: The COVID-19 pandemic exacerbated alcoholism and abuse, with increased heavy consumption (P < 0.001) and abuse (P = 0.0439). Access to medical programs for addressing alcohol abuse declined, highlighting the need for targeted intervention.

RESUMEN

Objective: To analyze the death of Brazilian pregnant and postpartum women due to COVID-19 or unspecific cause. Methods: This is retrospective, descriptive-exploratory, population-based study carried out with the Sistema de Informação de Vigilância Epidemiológica da Gripe (SIVEP-Gripe) database, with pregnant and postpartum women of reproductive age who died from confirmed COVID-19 between 2020 and 2021. The chosen variables were: age, gestational period, type and number of comorbidities, skin color, using the statistical software R Foundation for Statistical Computing Platform, version 4.0.3 and Statistical Package for Social Science, version 29.0 for analysis. Results: A total of 19,333 cases of pregnant and postpartum women aged between 10 and 55 years diagnosed with SARS were identified, whether due to confirmed COVID-19 or unspecific causes. Of these, 1,279 died, these cases were classified into two groups according to the cause of death: deaths from COVID-19 (n= 1,026) and deaths from SARS of unspecific cause (n= 253). Conclusion: The risk of death increased among black and brown women, in the postpartum period and with the presence of comorbidities, mainly diabetes, cardiovascular diseases and obesity. The data presented here draw attention to the number of deaths from SARS, especially among sociodemographic profiles, precarious access to health, such as the black population. In addition, limitations in adequate access to health care are reinforced by even lower rates of ICU admissions among women who died from SARS of an unspecified cause.

RESUMEN

BACKGROUND: The efficacy and safety of adjunctive statin therapy in hospitalized patients with coronavirus disease 2019 (Covid-19) remains uncertain. METHODS: We systematically searched Medline, Embase, Cochrane, and ClinicalTrials.gov databases from inception to late April 2024 for randomized controlled trials (RCTs) comparing statin versus no statin use in patients hospitalized with Covid-19. We pooled risk ratios (RRs) and hazard ratios (HRs) with 95% confidence intervals (CIs) applying a random-effects model. R version 4.3.1 was used for statistical analyses. RESULTS: We included 7 RCTs comprising 4,262 patients, of whom 2,645 (62%) were randomized to receive statin therapy. Compared with no statin, statin use significantly reduced case-fatality rate (RR 0.88; 95% CI 0.80-0.98; I2 = 0%). In a time-to-event analysis, we found similar results (HR 0.86; 95% CI 0.75-0.99; I2 = 0%). Statin use also significantly reduced World Health Organization (WHO) scale at 14 days (mean difference -0.27; 95% CI -0.54 to -0.01; I2 = 0%). There was no statistically significant difference between the two groups in length of hospital stay, elevation of liver enzymes, and C-reactive protein levels. CONCLUSIONS: In patients hospitalized with Covid-19, statins significantly reduced case-fatality rate and WHO scale score. REGISTRATION: A prospective register was recorded in International Prospective Register of Systematic Reviews (PROSPERO) with the number CRD42023479007.

RESUMEN

Protein ADP-ribosylation plays important but ill-defined roles in antiviral signalling cascades such as the interferon response. Several viruses of clinical interest, including coronaviruses, express hydrolases that reverse ADP-ribosylation catalysed by host enzymes, suggesting an important role for this modification in host-pathogen interactions. However, which ADP-ribosyltransferases mediate host ADP-ribosylation, what proteins and pathways they target and how these modifications affect viral infection and pathogenesis is currently unclear. Here we show that host ADP-ribosyltransferase activity induced by IFNγ signalling depends on PARP14 catalytic activity and that the PARP9/DTX3L complex is required to uphold PARP14 protein levels via post-translational mechanisms. Both the PARP9/DTX3L complex and PARP14 localise to IFNγ-induced cytoplasmic inclusions containing ADP-ribosylated proteins, and both PARP14 itself and DTX3L are likely targets of PARP14 ADP-ribosylation. We provide evidence that these modifications are hydrolysed by the SARS-CoV-2 Nsp3 macrodomain, shedding light on the intricate cross-regulation between IFN-induced ADP-ribosyltransferases and the potential roles of the coronavirus macrodomain in counteracting their activity.

RESUMEN

Background and Objectives: Medical and public recognition of "long-COVID or post-COVID syndrome", as well as its impact on the quality of life (QoL), is required to better address the disease burden. Objectives: We aimed to describe the persistence of COVID-19 symptoms and QoL among patients at three and twelve months after their discharge from the hospital. Materials and Methods: We conducted an observational, prospective, and longitudinal analytic study from September 2021 to April 2022. To measure QoL, we used a validated version of the 36-item Short-Form Health Survey (SF-36). Results: We included 68 patients in the study. A total of 54 (79.4%) patients reported at least one persistent symptom at three months vs. 52 (76.4%) at twelve months (p = 0.804). Some persistent symptoms (myalgia, alopecia, and cough) decreased significantly at twelve months (50% vs. 30.9%, 29.4% vs. 13.2%, and 23.5% vs. 7.4%; respectively, p = 0.007); in contrast, other persistent symptoms (sleep-wake and memory disorders) were more frequent (5.9% vs. 32.4% and 4.4% vs. 20.6%; respectively, p = ≤0.001). Regarding QoL, a statistically significant improvement was observed in some scores over time, p = ≤0.037. At twelve months, dyspnea, myalgia, and depression were risk factors associated with a poor physical component summary (PCS), p = ≤0.027, whereas anxiety, depression, and fatigue were associated with a poor mental component summary (MCS), p = ≤0.015. Conclusion: As the proportion of persistent symptoms at twelve months is high, we suggest that patients must continue under long-term follow up to reclassify, diagnose, and treat new onset symptoms/diseases.

RESUMEN

BACKGROUND: COVID-19 is a multisystemic disease characterized by respiratory distress. Disease severity is associated with several factors. Here we characterize virological findings and evaluate the association of laboratorial, epidemiological, virological findings and clinical outcomes of 251 patients during the first and second epidemic waves of COVID-19. METHODS: This transversal study used biological samples and data from patients hospitalized with COVID-19 between May 2020 and August 2021 in the metropolitan region of Cuiabá, Mato Grosso Brazil. Biological samples were subjected to RT-qPCR and MinION sequencing. Univariate and multivariate logistic regression and Odds ratio were used to correlate clinical, laboratorial, epidemiological data. FINDINGS: Patients were represented by males (61.7%) with mean age of 52.4 years, mild to moderate disease (49,0%), overweight/obese (69.3%), with comorbidities (66.1%) and evolving to death (55.38%). Severe cases showing symptoms for prolonged time, ≥ 25% of ground-glass opacities in the lungs and fatality rate increased significantly in second wave. Fatality was statistically associated to > 61 years of age,>25% ground-glass opacities in the lungs, immune, cardiac, or metabolic comorbidities. Higher viral load (p < 0.01/p = 0.02 in each wave), decreased erythrocyte (p < 0.01), hemoglobin (p < 0.05/p < 0.01), hematocrit (p < 0.01), RDW (p < 0.01), lymphocyte (p < 0.01), increased leucocyte (p < 0.01), neutrophil (p < 0.01) and CRP levels (p < 0.01) showed significant association with fatality in both waves, as did Neutrophil/Platelet (NPR; p < 0.01), Neutrophil/Lymphocyte (NLR; p < 0.01) and Monocyte/Lymphocyte ratio (MLR; p < 0.01). SARS-CoV-2 genomes from lineage B.1.1.33(n = 8) and Gamma/P.1(n = 15) shared 6/7 and 20/23 lineage-defining mutations, respectively. MAIN CONCLUSIONS: Severity and mortality of COVID-19 associated with a panel of epidemiological and laboratorial findings, being second wave, caused by Gamma variant, more severe in this in-hospital population.

RESUMEN

BACKGROUND: A distinct phenotype in Coronavirus disease 2019 (Covid-19) was observed in severe patients, consisting of a highly impaired interferon (IFN) type I response, an exacerbated inflammatory response. OBJECTIVE: The aim of the present study was to investigate a possible association of single nucleotide polymorphisms (SNPs), in five genes related to the immune response, rs3775291 in TLR3; rs2292151 in TICAM1; rs1758566 in IFNA1; rs1800629 in TNF, and rs1800795 in IL6 with the severity of Covid-19. METHODS: A cross-sectional study was performed, with non-severe and severe/critical patients diagnosed with Covid-19, by two public hospitals in Brazil. In total, 300 patients were genotyped for the SNPs, 150 with the non-severe form of the disease and 150 with severe/critical form. RESULTS: The T/T genotype of TLR3 in recessive model shows 58% of protection against severe/critical Covid-19; as well as the genotypes G/A+A/A of TICAM1 in dominant model with 60% of protection, and in a codominant model G/A with 57% and A/A with 71% of protection against severe/critical Covid-19. Comparing severe and critical cases, the T/C genotype of IFNA1 in the codominant model and TC+C/C in the dominant model showed twice the risk of critical Covid-19. CONCLUSION: We can conclude that rs3775291, rs2292151 and rs1758566 can influence the COVID-19 severity.

RESUMEN

At the beginning of December 2019, a new type of coronavirus emerged, SARS-CoV-2. This virus causes COVID-19, a highly contagious disease that can initially present asymptomatically and can also lead to death. Our ecological study goal was to evaluate the incidence, mortality, and lethality rates for COVID-19 between the states of Espírito Santo and Minas Gerais, with time series analysis using secondary and public databases on COVID-19 from January 2020 to December 2022. Prais-Winsten linear regression was used for trend analyses. In 2020, the rate in Espírito Santo was 2.19 times greater than in Minas Gerais. This trend continued in 2021, with Espírito Santo's rate being 1.29 times greater. In 2022, Espírito Santo's rate remained 2.65 times higher than Minas Gerais. Furthermore, Espírito Santo had the highest mortality, with the exception of 2021. In turn, Minas Gerais had the highest fatality rate throughout the analyzed pandemic period. The state of Espírito Santo had a higher incidence of COVID-19, as well as higher mortality when compared to the state of Minas Gerais. Furthermore, both states showed similar trends for mortality, lethality, and incidence in the years 2020 and 2021.

RESUMEN

We describe 5 children who had Rocky Mountain spotted fever (RMSF) and manifested clinical symptoms similar to multisystem inflammatory syndrome in Sonora, Mexico, where RMSF is hyperendemic. Physicians should consider RMSF in differential diagnoses of hospitalized patients with multisystem inflammatory syndrome to prevent illness and death caused by rickettsial disease.
