Prevalência de Influenza A, vírus sincicial respiratório eSARS-CoV-2 em pacientes com síndrome respiratóriaaguda grave em Passo Fundo, Rio Grande do Sul / Prevalence of Influenza A, respiratory syncytial virus andSARS-CoV-2 in patients with severe acute respiratorysyndrome in Passo Fundo, Rio Grande do Sul

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.

Concepciones de usuarios sobre nuevas vías de administración de profilaxis pre-exposición para el VIH / Users' expectations of the new pre-exposure prophylaxis for the HIV modalities

Resumen Este artículo tiene como objetivo discutir las concepciones de los Hombres Gay, Hombres Bisexuales y una Mujer Transgénero que usan o quieren usar profilaxis previa a la exposición por el virus de la inmunodeficiencia humana oral (PrEP) sobre nuevas vías de administración. Fueron entrevistados 17 usuarios del BCN Checkpoint. Las entrevistas fueron grabadas en audio, sometidas a análisis categorial temático teniendo en cuenta la perspectiva praxeográfica. Todos están adaptados al uso de la PrEP diaria y a demanda. En relación con las nuevas vías de administración (PrEP inyección intramuscular cada dos meses; pastilla mensual; inyección subcutánea cada seis meses) todos son muy receptivos a esas posibilidades, pero les falta información sobre las especificidades de cada una de ellas y una evaluación específica de sus necesidades. Tanto la satisfacción con el uso de PrEP oral, como las expectativas sobre las nuevas vías de administración son positivas. Sin embargo, lo más importante para los/a entrevistados/a es la garantía de que tendrán seguimiento para continuar cuidando de la salud afectivo-sexual, lo que no depende del tipo de vía de administración.

Abstract This article aims to discuss the expectations of Homosexual Men, Bisexual Men and a Transgender Woman, who use or want to use an oral pre-exposure prophylaxis (PrEP) for the human immunodeficiency virus (HIV) about PrEP modalities. Sixteen PrEP users, who are followed up in the BCN Checkpoint, were interviewed,. The interviews were audio-recorded, subjected to thematic categorical analysis within the theoretical framework from the praxiographic perspective. They are all adapted to the use of daily oral and event-based PrEP. In relation to the new PrEP modalities (monthly pill; intramuscular injection every two months; subcutaneous injection every six months), they are all very receptive to these possibilities, but they lack information on the specificities of each and specific assessment of their needs. Comments about the use of oral PrEP are positive, and expectations regarding the new PrEP modalities are visibly high. However, the most important thing for the interviewees is the guarantee that they will have follow-up appointments to continue taking care of their affective-sexual health, which is not dependent on the type of PrEP modalities.

Risk factors for acute kidney injury in patients hospitalized with COVID-19 / Fatores de risco para lesão renal aguda em pacientes hospitalizados com COVID-19

Abstract Introduction: Acute kidney injury (AKI) occurs frequently in COVID-19 patients and is associated with greater morbidity and mortality. Knowing the risks of AKI allows for identification, prevention, and timely treatment. This study aimed to identify the risk factors associated with AKI in hospitalized patients. Methods: A descriptive, retrospective, cross-sectional, and analytical component study of adult patients hospitalized with COVID-19 from March 1 to December 31, 2020 was carried out. AKI was defined by the creatinine criteria of the KDIGO-AKI guidelines. Information, regarding risk factors, was obtained from electronic medical records. Results: Out of the 934 patients, 42.93% developed AKI, 60.59% KDIGO-1, and 9.9% required renal replacement therapy. Patients with AKI had longer hospital stay, higher mortality, and required more intensive care unit (ICU) admission, mechanical ventilation, and vasopressor support. Multivariate analysis showed that age (OR 1.03; 95% CI 1.02-1.04), male sex (OR 2.13; 95% CI 1.49-3.04), diabetes mellitus (DM) (OR 1.55; 95% CI 1.04-2.32), chronic kidney disease (CKD) (OR 2.07; 95% CI 1.06-4.04), C-reactive protein (CRP) (OR 1.02; 95% CI 1.00-1.03), ICU admission (OR 1.81; 95% CI 1.04-3.16), and vasopressor support (OR 7.46; 95% CI 3.34-16.64) were risk factors for AKI, and that bicarbonate (OR 0.89; 95% CI 0.84-0.94) and partial pressure arterial oxygen/inspired oxygen fraction index (OR 0.99; 95% CI 0.98-0.99) could be protective factors. Conclusions: A high frequency of AKI was documented in COVID-19 patients, with several predictors: age, male sex, DM, CKD, CRP, ICU admission, and vasopressor support. AKI occurred more frequently in patients with higher disease severity and was associated with higher mortality and worse outcomes.

RESUMO Introdução: Lesão renal aguda (LRA) ocorre frequentemente em pacientes com COVID-19 e associa-se a maior morbidade e mortalidade. Conhecer riscos da LRA permite a identificação, prevenção e tratamento oportuno. Este estudo teve como objetivo identificar fatores de risco associados à LRA em pacientes hospitalizados. Métodos: Realizou-se estudo descritivo, retrospectivo, transversal e de componente analítico de pacientes adultos hospitalizados com COVID-19 de 1º de março a 31 de dezembro, 2020. Definiu-se a LRA pelos critérios de creatinina das diretrizes KDIGO-LRA. Informações sobre fatores de risco foram obtidas de prontuários eletrônicos. Resultados: Dos 934 pacientes, 42,93% desenvolveram LRA, 60,59% KDIGO-1 e 9,9% necessitaram de terapia renal substitutiva. Pacientes com LRA apresentaram maior tempo de internação, maior mortalidade e necessitaram de mais internações em UTIs, ventilação mecânica e suporte vasopressor. A análise multivariada mostrou que idade (OR 1,03; IC 95% 1,02-1,04), sexo masculino (OR 2,13; IC 95% 1,49-3,04), diabetes mellitus (DM) (OR 1,55; IC 95% 1,04-2,32), doença renal crônica (DRC) (OR 2,07; IC 95% 1,06-4,04), proteína C reativa (PCR) (OR 1,02; IC 95% 1,00-1,03), admissão em UTI (OR 1,81; IC 95% 1,04-3,16) e suporte vasopressor (OR 7,46; IC 95% 3,34-16,64) foram fatores de risco para LRA, e que bicarbonato (OR 0,89; IC 95% 0,84-0,94) e índice de pressão parcial de oxigênio arterial/fração inspirada de oxigênio (OR 0,99; IC 95% 0,98-0,99) poderiam ser fatores de proteção. Conclusões: Documentou-se alta frequência de LRA em pacientes com COVID-19, com diversos preditores: idade, sexo masculino, DM, DRC, PCR, admissão em UTI e suporte vasopressor. LRA ocorreu mais frequentemente em pacientes com maior gravidade da doença e associou-se a maior mortalidade e piores desfechos.

Niños hospitalizados con influenza en un hospital pediátrico de Argentina durante 2019-2022: ¿qué ha cambiado luego de la pandemia por COVID-19? / Children with influenza admitted at a children's hospital in Argentina in the 2019­2022 period: What has changed after the COVID-19 pandemic?

Introducción. Durante 2020 y 2021, la circulación de los virus influenza se mantuvo por debajo de lo esperado en todo el mundo. En Argentina, en el año 2022 observamos una circulación ininterrumpida de influenza todo el año. Nuestros objetivos fueron describir los patrones de circulación y las características clínicas de niños internados con influenza. Población y métodos. Estudio retrospectivo, analítico, observacional. Se incluyeron todos los niños internados en un centro pediátrico con detección del virus influenza durante los años 2019-2022. Resultados. Se internaron 138 pacientes en 4 años; en 2019 se observó una tasa del 4,5/1000 egresos hospitalarios mientras que en 2022, fue del 15,1/1000. En 2020 y 2021 no hubo casos. En el 2019 la mayoría de los casos ocurrieron en invierno, la causa de la internación fue la infección respiratoria aguda baja (IRAB) en el 79 % y se detectó influenza A en el 92 % de los casos. En el 2022, la mayoría de los casos ocurrieron en primavera, el 62 % presentó IRAB y en el 56 % se detectó influenza A. Ambos períodos tuvieron similares frecuencias de vacunación y de comorbilidades. Conclusiones. En el 2022 se registraron más internaciones por influenza, lo que podría corresponder a que se realizaron métodos diagnósticos moleculares, que son más sensibles, y se observó un cambio en la estacionalidad con más casos en primavera. En 2019 predominó influenza A en infecciones del tracto respiratorio inferior, mientras que en el 2022 influenza A y B fueron similares, y hubo más formas extrapulmonares.

Introduction. During 2020 and 2021, the circulation of influenza virus remained below expectations worldwide. In Argentina, in 2022, we observed an uninterrupted circulation of influenza all year round. Our objectives were to describe the circulation patterns and clinical characteristics of hospitalized children with influenza. Population and methods. Retrospective, analytical, observational study. All children with influenza virus admitted to a children's hospital during the 2019­2022 period were included. Results. A total of 138 patients were admitted over 4 years; in 2019, the rate of hospital discharges was 4.5/1000, compared to 15.1/1000 in 2022. No cases were recorded in 2020 and 2021. In 2019, most cases were observed in the winter; in 79%, the cause was acute lower respiratory tract infection (ALRTI); influenza A was detected in 92%. In 2022, most cases occurred in the spring; 62% developed ALRTI; and influenza A was detected in 56%. Similar rates of vaccination and comorbidities were observed in both periods. Conclusions. In 2022, more hospitalizations due to influenza were recorded, which may have correlated with the use of more sensitive molecular diagnostic testing and a change in seasonality, with more cases observed in the spring. In 2019, influenza A predominated in lower respiratory tract infections, while in 2022, cases of influenza A and B were similar, with more extra-pulmonary forms.

Antibody persistence 7 years after hepatitis-A vaccine in children with human immunodeficiency virus infection / Persistencia de anticuerpos siete años después de la vacuna de la hepatitis A en niños con infección por el virus de la inmunodeficiencia humana

Abstract Background: HIV-infected children have a higher risk of presenting infections, including the hepatitis A virus (HAV). The inactivated HAV vaccine is immunogenic in immunocompetent hosts; however, there are insufficient studies on the duration of seroprotection in HIV-infected children. Methods: An analytical cohort study was conducted. HIV-1-infected children who received the inactivated HAV vaccine (2 doses) were included. Blood samples were taken for antibody measurement, the first one 28 days after the second dose and another 7 years after the vaccination schedule. Information on viral load, immunological category, weight, height, and response to antiretroviral treatment from diagnosis to the last assessment was obtained. Results: 19 patients were included, with a mean age of 12.6 years (SD ± 2.29). 58% were male. 80% of the patients presented protective immunoglobulin G antibodies against HAV 7-year post-vaccination. The antibody concentration was found to be between 13 and 80 mIU/mL (median of 80 mIU/mL). 52% showed some degree of immunosuppression. There was no statistically significant relationship between the presence of seroprotection and viral load, treatment failure, immunological category, and malnutrition. Twelve patients presented with antiretroviral treatment failure, and in 33% of them, the antibodies did not offer satisfactory seroprotection. Conclusion: 7-year post-vaccination, 80% of HIV-infected children maintain seroprotection titers against HAV.

Resumen Introducción: Los niños infectados por el virus de la inmunodeficiencia humana (VIH) tienen mayor riesgo de presentar infecciones, incluyendo hepatitis por virus A (VHA). La vacuna inactivada contra el VHA es inmunógena en el huésped inmunocompetente. No hay estudios suficientes sobre el tiempo de seroprotección en niños infectados por el VIH. Método: Estudio de cohorte, analítico. Se incluyeron niños con infección por VIH-1 que recibieron la vacuna inactivada contra el VHA (dos dosis). Se les tomaron muestras sanguíneas para medición de anticuerpos, una 28 días después de la segunda dosis y otra 7 años después del esquema de vacunación. Se obtuvo información de carga viral, categoría inmunológica, peso y talla, y respuesta al tratamiento antirretroviral desde el diagnóstico hasta la última valoración. Resultados: Se incluyeron 19 pacientes con una edad media de 12.6 años (± 2.29). El 58% fueron del sexo masculino. El 80% de los pacientes presentaron anticuerpos immunoglobulin G (IgG) contra el VHA protectores a los 7 años de la vacunación. La concentración de anticuerpos se encontró entre 13 y 80 mUI/ml (mediana: 80 mUI/ml). El 52% mostraron algún grado de inmunosupresión. No existe relación estadísticamente significativa entre la presencia de seroprotección y la carga viral, la falla al tratamiento, la categoría inmunológica ni la desnutrición. Doce pacientes presentaron falla al tratamiento antirretroviral; en el 33% de ellos los anticuerpos no ofrecían seroprotección satisfactoria. Conclusiones: A 7 años posvacunación, el 80% de los niños con VIH mantienen títulos de seroprotección frente al VHA.

Immune Deficiency/Dysregulation Associated Lymphoid Proliferations, EBV+ In Persons Living With HIV

ABSTRACT Background: The 5th edition of the World Health Organization Classification of Hematolymphoid Tumors recently defined immune deficiency/dysregulation (IDD)-associated-lymphoid-proliferations in HIV settings, where information is scarce, often gone under or misdiagnosed. Objectives: To describe the clinical picture, histopathology, and outcomes of IDD-associated-lymphoid-proliferations Epstein-Barr virus+ (EBV) in people living with HIV without organ transplantation, antiretroviral therapy (ART) treated. Methods: HIV+ patients diagnosed with IDD-associated-lymphoid-proliferations seen at an academic medical center in Mexico from 2016 to 2019 were included. Immunohistochemical studies, in situ hybridization, and polymerase chain reaction analysis for EBV and LMP1 gene deletions were performed and correlated with clinical data. Results: We included 27 patients, all men who have sex with men, median age 36 years (interquartile range [IQR] 22-54). The median baseline CD4+ T cells were 113/mL (IQR 89-243), the CD4+/CD8+ ratio was 0.15 (IQR: 0.09-0.22), and the HIV viral load was 184,280 copies/mL (IQR: 76,000-515,707). Twenty patients (74.07%) had IDD-associated-lymphoid-proliferations hyperplasia plasma cell type EBV+, 3 (11.1%) had hyperplasia mononucleosis-like type (IM-type), 1 patient (3.70%) had florid follicular hyperplasia, 3 (11.1%) IDD-associated-lymphoid-proliferations polymorphic type, and there were 22 cases (81.4%) of synchronic Kaposi Sarcoma. Two patients were diagnosed with Hodgkin lymphoma following a second positron emission tomography-computed tomography scan-guided biopsy. The median follow-up was 228 weeks (IQR 50-269); 6 patients died (22.2%) of causes unrelated to IDD-associated-lymphoid-proliferations related. Conclusion: IDD-associated-lymphoid-proliferations EBV+ occured in severely immunosuppressed HIV+ patients, a high percentage of whom had concomitant Kaposi sarcoma. The prognosis was good in patients treated only with ART.

Características de recién nacidos hijos de madre con IgM positiva para el Virus Herpes Simplex

Introducción: El herpes connatal es una entidad infrecuente asociada a elevada morbimortalidad. La probabilidad de transmisión al recién nacido va de 5% al 85%. El diagnóstico se dificulta por falta de clínica, serología no confiable y por la no disponibilidad de PCR en los servicios públicos de países en vías de desarrollo. La IgM en gestantes podría ser utilizada como un marcador de sospecha para evaluar al neonato. Objetivo: Caracterizar a los recién nacidos, hijos de gestantes con IgM positiva para HVS 1-2 y la frecuencia de encefalitis en los infantes. Materiales y métodos : Estudio observacional, descriptivo, prospectivo, realizado de mayo de 2020 a octubre de 2021. Se incluyeron recién nacidos (RN) de madres con IgM positiva para Herpes Virus Simplex (HVS) a partir de la segunda mitad del embarazo. En el RN se realizó serología IgG e IgM, y además, PCR- RT para HVS 1-2 en sangre y/o LCR, excluyéndose los nacidos en otras maternidades y/o sin datos de serología materna. Resultados: 36 pacientes. Edad materna 28 años (DS + 4), 5% con antecedentes de HVS, 61% cesárea. 36% prematuros, 13% RCIU. Síntomas agudos en el RN 22%. De ellos, 19% plaquetopenia, 44% alteración de GOT. 63% PCR HVS en sangre y 44% en LCR. Se encontró hemorragia, hidrocefalia, leucomalacia en 27%. No se encontró diferencias en la expresión clínica por tipo de parto. Conclusiones: Los RN hijos de gestantes con IgM positiva para VHS desde la segunda mitad del embarazo o periparto, presentaron infección por VHS determinada por PCR en sangre o LCR, independiente de la vía del parto. El diagnóstico serológico en embarazadas permite la pesquisa, diagnóstico y tratamiento temprano del RN.

Introduction: neonatal herpes is a rare entity associated with high morbidity and mortality. The probability of transmission to the newborn ranges from 5% to 85%. The diagnosis is difficult due to the lack of clinical signs, unreliable serology and the non-availability of PCR in public services in developing countries. IgM in pregnant women could be used as a suspected marker to evaluate the neonate. Objective: To characterize newborn children of pregnant women with positive IgM for HSV 1-2 and the prevalence of encephalitis in infants. Materials and methods: Observational, descriptive, prospective study, carried out from May 2020 to October 2021. Newborns (NB) of mothers with positive IgM for Herpes Virus Simplex (HSV) from the second half of pregnancy were included. In newborns, IgG and IgM were performed, and in addition, PCR-RT for HSV 1-2 in blood and/or CSF, excluding those born in other hospitales and/or without maternal serology data. Results: We included 36 patients. Maternal age was 28 years (DS + 4), 5% with a history of HSV. 61% were delivered via cesarean section, 36% were premature, 13% had IUGR. 22% of the newborns had acute symptoms. 19% had thrombocytopenia, 44% had GOT alteration. 63% were PCR positive for HSV in serum and 44% were CSF-positive. Hemorrhage, hydrocephalus and leukomalacia were found in 27%. No differences were found in clinical expression by type of delivery. Conclusions: Newborns born to pregnant women with positive IgM for HSV from the second half of pregnancy or peripartum, presented HSV infection as determined by PCR in blood or CSF, regardless of the route of delivery. Serological diagnosis in pregnant women allows early screening, diagnosis and treatment of the NB.

Persistencia de signos y síntomas a los 6 meses posinfección por chikungunya en pacientes de un hospital público en Paraguay

Introducción: El virus chikungunya (CHIKV) causa una enfermedad con manifestaciones agudas bien documentadas, pero existen pocos datos sobre la persistencia de síntomas y secuelas a largo plazo. Objetivos: Evaluar la persistencia de signos, síntomas y factores asociados en pacientes con infección por CHIKV en un seguimiento de 6 meses posinfección. Materiales y métodos: Estudio de cohorte ambispectivo que incluyó casos confirmados de CHIKV notificados en abril de 2023 en Coronel Oviedo, Paraguay. Se realizaron entrevistas al mes, a los tres meses y a los 6 meses posinfección. Se analizaron características demográficas, comorbilidades, manifestaciones reumáticas y sintomáticas. Resultados: Ingresaron 333 participantes, completando seguimiento a 6 meses 170 pacientes. A los 6 meses persistieron: dolor de espalda (61.2%), artritis (57.1%), cefalea (54.1%), fatiga (51.2%), mialgia (49.4%), debilidad (47.6%), depresión (45.9%) y artralgia (45.9%). La persistencia de artritis (OR 7.54; p=0.008) y mialgia (OR 3.24; p=0.031) a 6 meses fue mayor en el grupo de 36-45 años. Conclusiones: Alta persistencia de síntomas musculoesqueléticos y fatiga hasta 6 meses posinfección, con tendencia decreciente, pero exacerbación de depresión. Edad entre 36-45 años asociada a mayor persistencia. Se requieren protocolos de seguimiento integral, investigar mecanismos fisiopatológicos y fortalecer prevención, dado el impacto individual y socioeconómico de la enfermedad.

Introduction: Chikungunya virus (CHIKV) causes a disease with well-documented acute manifestations, but there is limited data on the persistence of symptoms and long-term sequelae. Objectives: To evaluate the persistence of signs, symptoms, and associated factors in patients with CHIKV infection during a 6-month post-infection follow-up. Material and Methods: An ambispective cohort study that included confirmed cases of CHIKV reported in April 2023 in Coronel Oviedo, Paraguay. Interviews were conducted at 1, 3 and 6 months post-infection. Demographic characteristics, comorbidities, rheumatic, and symptomatic manifestations were analyzed. Results: 333 participants were enrolled, with 170 patients completing the 6-month follow-up. At 6 months, the following symptoms persisted: back pain (61.2%), arthritis (57.1%), headache (54.1%), fatigue (51.2%), myalgia (49.4%), weakness (47.6%), depression (45.9%), and arthralgia (45.9%). The persistence of arthritis (OR 7.54, p=0.008) and myalgia (OR 3.24, p=0.031) at 6 months was higher in the 36-45 age group. Conclusions: High persistence of musculoskeletal symptoms and fatigue up to 6 months post-infection, with a decreasing trend but exacerbation of depression. Age between 36-45 years was associated with greater persistence. Comprehensive follow-up protocols, investigation of pathophysiological mechanisms, and strengthening prevention are required, given the individual and socioeconomic impact of the disease.

Do oral antiseptics used in the dental routine have anti-viral efficacy? a systematic review of in vitro studies / Os antissépticos orais utilizados na rotina odontológica têm eficácia anti-viral? Uma revisão sistemática de estudos in vitro / ¿Los antisépticos orales utilizados en la rutina odontológica tienen eficacia antiviral? Una revisión sistemática de estudios in vitro

Introduction: Mouthwashes play an important role in the dental clinic, but their role on viruses requires investigation. Objective:to review in vitro studies to identify the effect of different mouthwashes on the main viruses associated with routine dental care. Methodology:The following databases were searched in September 2023: PubMed, Embase, Scopus and Web of Science databases; the Cochrane Library and the Virtual Health Library (VHL); and grey literature. In vitro studies that used mouthwashes to reduce the viral load were selected. The PICOS strategy was considered to define eligibility criteria: the Population (viruses involved in the etiology of oral infection), the Intervention (oral antiseptics), the appropriate comparator (positive and negative controls), the Outcomes of interest (reduction of viral load) and the Study design (in vitro studies). Results:Considering the eligibility criteria, 19 articles were included in this review. The efficacy of povidone-iodine (PVP-I), chlorhexidine, Listerine®, essential oils, and cetylpyridinium chloride (CPC) rinses were investigated. PVP-I (0.23%) had its effects mainly associated with coronaviruses SARS(Severe Acute Respiratory Syndrome),demonstrating a significant reduction in viral load after 15 seconds of exposure. Chlorhexidine (0.05%; 0.1% and 0.5%) was ineffective against adenovirus, poliovirus, and rhinovirus respiratory viruses. Listerine® demonstrated superior efficacy against HSV-1 and 2 viruses and influenza A, and cetylpyridine chloride also demonstrated virucidal activity against influenza A. Conclusions:The type, concentration, and time of exposure to antiseptics varied between studies. PVP-I and chlorhexidine digluconate were the most studied substances, butin general, PVP-I was more effective in reducing viral titers, especially concerning coronaviruses. Other antiseptics such as CPC, H2O2 and Listerine® have also shown significant reduction in viral load, but this is a limited number of studies (AU).

Introdução: Os enxaguantes bucais desempenham um papel importante na clínica odontológico, porém seu papel sobre os vírus requer investigações. Objetivo: revisar estudos in vitro para identificar o efeito de diferentes colutórios sobre os principais vírus associados ao atendimento odontológico de rotina. Metodologia: As seguintes bases foram pesquisadas até setembro de 2023: PubMed, Embase, Scopus e Web of Science; a Biblioteca Cochrane e a Biblioteca Virtual em Saúde (BVS); e literatura cinzenta. Foram selecionados estudos in vitro que utilizaram bochechos com o objetivo de reduzir a carga viral. A estratégia PICOS foi considerada para a definição dos critérios de elegibilidade: População (vírus envolvidos na etiologia da infecção oral), Intervenção (antissépticos orais), Comparador (controles positivos e negativos), os Desfechos de interesse (redução da carga viral) e o desenho do estudo (estudos in vitro). Resultados: Considerando os critérios de elegibilidade, 19 artigos foram incluídos para esta revisão. A eficácia da povidona-iodo (PVP-I), clorexidina, Listerine®, óleos essenciais e lavagens com cloreto de cetilpiridínio foram investigadas. O PVP-I(0.23%)teve seus efeitos principalmente associados ao coronavírusSARS (Síndrome Respiratória Aguda Severa),demonstrando uma redução significativa da carga viral após 15 segundos de exposição. A clorexidina mostrou-se ineficaz contra vírus respiratórios de adenovírus, poliovírus e rinovírus. Listerine® demonstrou eficácia superior contra vírus HSV-1 e 2 e vírus influenza A, e cloreto de cetilpiridinio também demonstrou atividade virucida contra influenza A.Conclusões:O tipo, concentração e tempo de exposição aos antissépticos variaram entre os estudos. O PVP-I e o digluconato de clorexidina foram as substâncias mais estudadas, mas no geral, o PVP-I foi mais eficaz na redução dos títulos virais, principalmente no que diz respeito aos coronavírus. Outros antissépticos como CPC, H2O2 e Listerine® também mostraram redução significativa da carga viral, mas trata-se de um número limitado de estudos (AU).

Gravedad y complicaciones en lactantes con infección por el virus respiratorio sincitial posterior a la pandemia por SARS-CoV-2 / Severity and complications in infants with respiratory syncytial virus infection after the SARS-CoV-2 pandemic

Resumen Introducción: Posterior a la pandemia por SARS-CoV-2 se ha observado un incremento en la hospitalización por virus respiratorio sincitial (VRS), con mayores complicaciones. Se han encontrado alteraciones extrapulmonares asociadas, disfunción biventricular y lesión renal aguda, entre otras. El objetivo de este estudio fue analizar la evolución y las complicaciones en niños hospitalizados con enfermedad respiratoria de vías bajas secundaria a infección por VRS tras la pandemia de COVID-19. Métodos: Se incluyeron todos los menores de 2 años que ingresaron al servicio de urgencias con infección por VRS. Se analizaron las características clínicas, la necesidad de oxígeno suplementario, el uso de aminas, el índice de angina renal y el requerimiento de terapia de sustitución renal. Se realizó ecografía pulmonar al ingreso. En el análisis estadístico, para las variables cuantitativas se determinaron la media y la desviación estándar, y para las variables cualitativas la frecuencia y el porcentaje. Se evaluaron las diferencias de la distribución con la prueba exacta de Fisher. Resultados: Hubo 45 pacientes con infección por VRS. El 26.7% requirieron ventilación mecánica invasiva y el 11.1% diálisis peritoneal. La letalidad fue de cuatro casos, tres de ellos menores de 12 meses con puntuación de LUS > 7; esto contrasta con el 90.2% de los sobrevivientes con puntaje < 7 (p = 0.0004). Conclusiones: Se observó un aumento en la incidencia de bronquiolitis tras la pandemia, en más de la mitad de los casos con cuadros de moderados a graves, y todos requirieron oxígeno suplementario al ingreso. La lesión renal aguda fue la manifestación extrapulmonar más frecuente.

Abstract Background: After the SARS-CoV-2 pandemic, there has been an increase in hospitalization for lower respiratory infection secondary to respiratory syncytial virus (RSV), with greater complications. Associated extrapulmonary alterations, biventricular dysfunction, acute kidney injury, among others, have been found. The objective of this study was to analize the evolution and complications in hospitalized children with lower respiratory infection secondary to RSV after COVID-19 pandemic. Methods: All pediatric patients under 2 years of age admitted to the emergency department with RSV infection were included. Clinical characteristics, need for supplemental oxygen, use of amines, renal angina index, and requirement for renal replacement therapy were analyzed. Lung ultrasound was performed upon admission. Statistical analysis was carried out for the quantitative variables by means of mean and standard deviation, and qualitative variables by frequency and percentage. Differences in the distribution were evaluated with Fisher’s exact distribution. Results: 45 patients with RSV infection were identified, 26.7% required invasive mechanical ventilation and 11.1% requiered peritoneal dialysis. Fatality was observed in four cases, three of these younger than 12 months with a LUS score > 7; contrasts with 90.2% of survivors with a score < 7 (p = 0.0004). Conclusions: An increase in the incidence of bronchiolitis after pandemic was observed, with more than half having moderate to severe symptoms and requiring supplemental oxygen support in all patients upon admission. Acute kidney injury is the most common extrapulmonary manifestation.

Mycobacterium tuberculosis y virus linfotrópico humano, una co-infección fatal / Mycobacterium tuberculosis and human lymphotropic virus, a fatal co-infection

La tuberculosis es una infección de alta incidencia en Latinoamérica. Su presentación como infección activa está determinada por factores de riesgo del hospedero. Comunicamos el caso clínico de una mujer joven que presentó una forma grave de tuberculosis pulmonar. Al explorar sus factores de riesgo se confirmó un estado de inmunosupresión profundo, causado por un linfoma de células T, asociada a una co-infección por virus linfotrópico T humano tipo 1. Se destacan los aspectos microbiológicos y de pronóstico de la co-infección de Mycobacterium tuberculosis y HTLV-1

Tuberculosis is a high-incidence infection in Latin America. Its presentation as an active infection is determined by risk factors in the host. We report the case of a young woman who presented a severe form of pulmonary tuberculosis. When exploring her risk factors, a profound state of immunosuppression was found, caused by T-cell lymphoma, associated with co-infection with human lymphotropic virus. Microbiological and prognostic aspects of Mycobacterium tuberculosis and HTLV-1 co-infection are highlighted.

Estado nutricional de crianças com microcefalia congênita transmitida pelo vírus Zika / Nutritional status of children with congenital microcephaly transmitted by Zika Virus / Estado nutricional de niños con microcefalia congénita transmitida por el Virus Zika

A microcefalia é uma condição sem tratamento causa alterações de cunho sensorial, cognitivo, motor, auditivo e visual, podendo ser adquirida por meio da infecção congênita pelo vírus Zika. O objetivo desta pesquisa foi avaliar o estado nutricional, o consumo alimentar e os fatores socioeconômicos que implicam na alimentação das crianças com microcefalia oriunda da infecção pelo Zika Vírus. Este estudo é uma pesquisa de campo descritiva, de delineamento transversal, que foi realizada com dez crianças na faixa etária de 2 a 3 anos. O estado nutricional foi avaliado utilizando balança digital e fita métrica, e os questionários sobre o consumo alimentar e condições socioeconômicas foram respondidos pelos cuidadores das crianças. Os resultados encontrados apresentaram inadequações das seguintes maneiras: 60% na estatura por idade, 50% no peso por idade e 40% no peso por estatura. Sobre a alimentação, 70% tinham uma alimentação inadequada e 60% apresentavam condições socioeconômicas de risco. Perante os achados, é possível interligar os fatores pesquisados com um retardo no desenvolvimento infantil. Portanto, ressalta-se que a microcefalia associada à alimentação inadequada e baixa condição social é capaz de agravar o estado nutricional.

Microcephaly is an untreated condition that leads to sensory, cognitive, motor, auditory and visual changes and can be acquired through congenital infection by the Zika Virus. Hence, this study evaluates the nutritional status, food consumption and socioeconomic factors that affect the nutrition of children with microcephaly transmitted by Zika Virus infection. A descriptive, cross-sectional field research was conducted with ten children aged 2 to 3 years. Nutritional status was assessed using a digital scale and measuring tape. Questionnaires on food consumption and socioeconomic conditions were answered by the children's caregivers. The results found presented the following inadequacies: 60% in height for age, 50% in weight for age, and 40% in weight for height. Regarding nutrition, 70% of the children had inadequate nutrition and 60% lived under risky socioeconomic conditions. Given these findings, the factors researched can be linked with a delay in child development. Therefore, microcephaly associated with inadequate nutrition and low social status can worsen nutritional status.

La microcefalia es una afección no tratada que conlleva cambios sensoriales, cognitivos, motores, auditivos y visuales, y puede adquirirse a través de una infección congénita por el virus Zika. El objetivo de este estudio fue evaluar el estado nutricional, el consumo de alimentos y los factores socioeconómicos que afectan la nutrición de niños con microcefalia provocada por la infección por el virus Zika. Se trata de un estudio descriptivo, de enfoque transversal, que se realizó con 10 niños de entre 2 y 3 años. El estado nutricional se evaluó mediante una balanza digital y una cinta métrica, y los cuidadores de los niños respondieron cuestionarios sobre consumo de alimentos y condiciones socioeconómicas. Los resultados encontrados presentaron insuficiencias en los siguientes aspectos: 60% en talla para la edad, 50% en peso para la edad y 40% en peso para la talla. En cuanto a la nutrición, el 70% tenía una nutrición inadecuada y el 60% tenía condiciones socioeconómicas de riesgo. Teniendo en cuenta los hallazgos, es posible relacionar los factores investigados con un retraso en el desarrollo infantil. Por tanto, cabe destacar que la microcefalia asociada a una nutrición inadecuada y un bajo estatus social es capaz de empeorar el estado nutricional.

HIV and childhood tuberculosis: fragmentation of the flow of information in the countryside of the state of São Paulo / HIV e tuberculose infantil: a fragmentação do fluxo de informação no interior paulista / VIH y tuberculosis infantil: la fragmentación del flujo de información en el interior del estado de São Paulo

Background and objectives: children are still affected by HIV and tuberculosis (TB). This study aimed to identify the occurrence of HIV and TB cases in children. Methods: this is an epidemiological, non-experimental, retrospective study, in which the population was made up of records of HIV and TB cases in children living in a municipality in the countryside of the state of São Paulo, from 2012 to 2022, in the age group of zero to 13 years old. After data collection, data consistency and validity was checked, followed by categorization of information for descriptive analyses and presentation in absolute and relative frequency tables. Results: during the study period, six HIV cases and seven TB cases were identified in children with a respective average annual incidence of 0.033 and 0.031 cases/1,000 inhabitants aged up to 13 years. There were 146 notifications of HIV-exposed children. There was a difference of months to years between the dates of diagnosis and notification, which deviates from the Ministry of Health recommendations. Incompatibility was found between municipal and state registration platforms, which shows a breakdown in flow of information on notifications. Conclusion: there have been HIV and childhood TB cases in the last ten years. Structural problems were identified in the fragmentation of the flow of information that subsidizes health actions according to the population's needs, which overshadows the health system's ability to respond.(AU)

Justificativa e Objetivos: crianças ainda são afetadas pelo HIV e pela tuberculose (TB). Dessa forma, o objetivo do estudo foi identificar a ocorrência de casos de HIV e TB em crianças. Métodos: trata-se de estudo epidemiológico, não experimental, retrospectivo, em que a população foi constituída pelo registro de casos infantis de HIV e TB residentes em um município do interior do estado de São Paulo, no período de 2012 a 2022, na faixa etária de zero a 13 anos de idade. Após a coleta de dados, foi realizada a verificação de consistência e validade dos dados, seguida do tratamento categorizado das informações para análises descritivas e apresentação em tabelas de frequência absoluta e relativa. Resultados: no período de estudo, foram identificados seis casos de HIV e sete de TB em crianças com média anual respectiva de 0,033 e 0,031 casos/1.000 habitantes com idade até 13 anos. Verificaram-se 146 notificações de criança exposta ao HIV. Houve diferença de meses a anos entre as datas de diagnóstico e de notificação, o que diverge do recomendado pelo Ministério da Saúde. Foi verificada a incompatibilidade entre plataformas de registro de âmbito municipal e estadual, o que evidencia uma quebra do fluxo de informação das notificações. Conclusão: houve ocorrência de casos de HIV e TB infantil nos últimos dez anos. Foram identificados problemas estruturais na fragmentação do fluxo da informação que subsidia ações de saúde de acordo com as necessidades da população, o que ofusca a capacidade de resposta do sistema de saúde.(AU)

Antecedentes y Objetivos: los niños siguen estando afectados por el VIH y la tuberculosis (TB). El objetivo de este estudio fue identificar la ocurrencia de casos de VIH y TB en niños. Métodos: se trata de un estudio epidemiológico, no experimental, retrospectivo, en el cual la población fue constituida por los registros de casos de VIH y TB en niños residentes en un municipio del interior del estado de São Paulo entre 2012 y 2022, con edad entre cero y 13 años. Después de la recolección de datos, se verificó la consistencia y validez de los mismos, seguido del tratamiento categorizado de la información para análisis descriptivos y presentación en tablas de frecuencias absolutas y relativas. Resultados: durante el periodo de estudio, se identificaron seis casos de VIH y siete de TB en niños, con una incidencia media anual respectiva de 0,033 y 0,031 casos/1.000 habitantes de hasta 13 años. Hubo 146 notificaciones de niños expuestos al VIH. Hubo una diferencia de meses a años entre las fechas de diagnóstico y notificación, lo que se desvía de lo recomendado por el Ministerio de Salud. Hubo incompatibilidad entre las plataformas de registro municipal y estatal, lo que muestra una ruptura en el flujo de información sobre las notificaciones. Conclusión: se han registrado casos de VIH y de tuberculosis infantil en los últimos diez años. Se identificaron problemas estructurales en la fragmentación del flujo de información que subvenciona las acciones sanitarias según las necesidades de la población, lo que ensombrece la capacidad de respuesta del sistema sanitario.(AU)

Epidemiological profile of individuals with HIV/Aids in a municipality in Maranhão State, Brazil, from 2017 to 2020 / Perfil epidemiológico de individuos con VIH/SIDA en municipio en Maranhão, Brasil, de 2017 a 2020 / Perfil epidemiológico de indivíduos com HIV/Aids em município no Maranhão, Brasil, de 2017 a 2020

Background and Objective: To understand the main forms of transmission of HIV in order to foster the containment of the transmission chain, early diagnosis and the epidemiological profile of patients. In this sense, it will enable the analysis of the epidemiological profile and the transmissibility variables of patients with HIV/Aids from the municipality of Imperatriz-MA.. Method: This is an observational cross-sectional study. Data collection was performed from the analysis of patients' records registered in the Center for Testing and Counseling (CTA) from 2017 to 2020. For data collection, a questionnaire with transmission variables and epidemiological characteristics of patients was used. Results: From January 2017 to December 2020, 211 medical records were filed. Of these, 71.6% were male, 55.5% of the participants were between 21 and 40 years, and 66.4% from Imperatriz-MA. The most prevalent type of exposure was sexual intercourse without a condom. Among the participants, 83.9% (n=177) were positive only for HIV. About 140 people with HIV had an undetectable viral load (VL) (< 50 copies/ml) after 6 months of using antiretroviral therapy, making it low transmissibility. Conclusion: The study was able to characterize the epidemiological profile of patients from the Specialized Assistance Service (SAE) in Imperatriz between 2017 and 2020. Despite the increase in the number of cases among women, the most affected public remains young men, from 21 to 40 years of age, with 8 to 11 years of education, single and brown. Sexual intercourse without a condom is the main type of exposure.(AU)

Tumor de Buschke-Löwenstein en el embarazo adolescente / Buschke-Löwenstein Tumor in Adolescent Pregnancy

Resumen El tumor de Buschke-Löwenstein, también denominado condiloma acuminado gigante, es una entidad rara causada por el virus del papiloma humano (VPH), con una incidencia de 0.01% en la población en general y solo 6 casos reportados en embarazadas. No existe un consenso con respecto al tratamiento; sin embargo, la cirugía es la técnica más descrita. Caso clínico: Paciente primigesta de 14 años, con un embarazo de 21 semanas de gestación, quien ingresó a urgencias por una masa dolorosa en región perineal de 5 meses de evolución. A la exploración física se encontraron en región perineal 2 lesiones exofíticas, coliformes, irregulares, ulceradas de aproximadamente 20 × 10 cm con presencia de secreción amarillenta fétida. Se realizó escisión del tumor con amplios márgenes quirúrgicos y cierre por segunda intención. Por parte de patología se reportó un condiloma acuminado gigante sin lesión en borde quirúrgico. La prueba por PCR detectó el genotipo 53 del virus de papiloma humano. Después de 12 semanas se presentó epitelización completa, sin complicaciones. Conclusión: El tumor de Buschke-Löwenstein es considerado como benigno, no obstante, representa cierto grado de malignidad y tiende a recurrir después del tratamiento, por lo que es importante reforzar las medidas de tamizaje y prevención del Virus del Papiloma Humano.

Abstract Buschke-Löwenstein tumor also called giant condyloma acuminatum is a rare condition due to the human papillomavirus with an incidence of 0.01% and just 6 cases reported in pregnancy. There is no consensus on the treatment, although surgery has been the most reported. Clinical case: A 14 year-old primigravid patient with a 21- week pregnancy who was admitted to the Emergency Department due to a perineal painful tumor which appeared 5 months before. On physical examination two irregular exophytic, cauliflower-like and ulcerated lesions of 20 × 10 cm of size each one with malodorous discharge were found on her perineal region suggestive of giant condyloma acuminatum. We decided to resect the tumor with tumor-free margin control and healing per secundam. The pathology report showed a giant condyloma acuminatum with tumor-free margin. The PCR analysis revealed human papillomavirus genotype 53. Complete epithelialization was noted at 12 weeks with no complications noted. Conclusion: Buschke-Löwenstein tumor is considered as a benign tumor, but it carries a risk of malignant transformation and it can appear after treatment, which makes important to strengthen the prevention and screening of human papillomavirus.

Longitudinal Trends in HIV-1 Subtypes and Drug Resistance in Children from Argentina over a 15-Year Period (2006-2021)

ABSTRACT Background: Human immunodeficiency virus (HIV) drug resistance is a major cause of treatment failure in children and adolescents infected with the virus. Objectives: The objectives of the study are to investigate HIV drug resistance (HIVDR) in patients who attended a referral care center in Argentina over a 15-year period and to compare mutational patterns between HIV-1 pol sequences characterized as B or BF recombinants. Methods: Individual resistance-associated mutations (RAMs) (to protease and reverse transcriptase inhibitors) were identified according to IAS-USA guidelines in 374 HIV-1-infected children and adolescents. HIV-1 subtype was characterized by phylogenetic and recombination analysis using MEGA5.1 and Simplot. Poisson linear regression was used to model the dynamics of the RAMs over time. Results: The prevalence of RAMs to protease inhibitors (R2 = 0.52, p = 0.0012) and nucleoside reverse transcriptase inhibitors (R2 = 0.30, p = 0.0225) decreased over time. HIVDR to non-nucleoside reverse transcriptase inhibitors remained moderate to high, ranging between 33% and 76%. BF recombinants showed a higher frequency of thymidine analog mutation 1 RAMs profile and I54V mutation. Conclusion: In Argentina, HIVDR observed in children and adolescents has decreased over the past 15 years, regardless of the viral subtype.

Resistencia a los inhibidores de la integrasa en niños con el virus de la inmunodeficiencia humana por transmisión vertical: primeros casos en Uruguay / Resistance to integrase inhibitors in children with vertically-transmitted human immunodeficiency virus: First cases in Uruguay

La resistencia a los antirretrovirales (ARV) es un problema de salud pública. Con el uso de inhibidores de la integrasa (INSTI) en pediatría, también comienzan a aparecer resistencias. El objetivo de esta comunicación es describir 3 casos con resistencia a los INSTI. Se describen 3 pacientes pediátricos con transmisión vertical del virus de la inmunodeficiencia humana (VIH). Iniciaron ARV de lactantes y preescolares, con mala adherencia al tratamiento, cursaron con diferentes planes secundarios a comorbilidades asociadas y fallas virológicas por resistencia. Los 3 casos clínicos describen la rápida aparición de resistencia frente a la falla virológica y el compromiso de los INSTI. La adherencia debe ser supervisada para detectar precozmente el aumento de la viremia. La falla virológica en un paciente tratado con raltegravir obliga a un rápido cambio de esquema ARV, ya que continuar utilizándolo podría favorecer nuevas mutaciones y resistencia a los INSTI de segunda generación.

Antiretroviral (ARV) drug resistance is a public health issue. Resistance has also been observed in the case of integrase strand transfer inhibitors (INSTIs) used in pediatrics. The objective of this article is to describe 3 cases of INSTI resistance. These are the cases of 3 children with vertically-transmitted human immunodeficiency virus (HIV). They were started on ARVs as infants and preschoolers, with poor treatment adherence, and had different management plans due to associated comorbidities and virological failure due to resistance. In the 3 cases, resistance developed rapidly as a result of virological failure and INSTI involvement. Treatment adherence should be monitored so that any increase in viremia can be detected early. Virological failure in a patient treated with raltegravir forces to a rapid change in ARV therapy because its continued use may favor new mutations and resistance to second-generation INSTIs.
