ABSTRACT

INTRODUCTION: Meningeal cryptococcosis (MC) is a frequent cause of meningoencephalitis in people living with HIV (PLHIV), leading to substantial morbidity (20-55%). Clinical characteristics, lethality and adverse prognostic factors in PLHIV with MC admitted to intensive care units (ICUs) are described. METHODS: A retrospective observational study. Period from 11/21/2006 to 05/24/2023. It involved 154 adult PLHIV diagnosed with MC and admitted to ICUs. Percentages and absolute values were compared by Chi-Square or Fisher's test and medians by Mann-Whitney test. The association with mortality was assessed by logistic regression. SPSS 23.0 software was used. A p-value <0.05 was considered significant. RESULTS: Patients who died and those who survived were comparable in age and sex (p>0.05). Univariate analysis showed that impaired functional and nutritional status, lack of previous highly active antiretroviral therapy, CD4 <100 cells, APACHE II ≥ 13 and a PLHIV prognostic score ≥ 8 points, requiring mechanical ventilation (MV), respiratory failure, renal failure, neurological dysfunction or sepsis could be associated (p<0.05) with mortality. Logistic regression established that impaired functional and nutritional status, a PLHIV prognostic score ≥ 8, need for MV and presence of sepsis would be independent variables associated with mortality. CONCLUSION: The results indicate that altered functional and nutritional status, a PLHIV prognostic score ≥ 8 points, requiring MV and suffering sepsis on admission to the ICU are more frequent in deceased patients, and they could therefore serve as independent variables to predict a higher risk of mortality.


Introducción: La criptococosis meníngea (CM) es una causa frecuente de meningoencefalitis en personas que viven con HIV (PVHIV) y produce una importante morbimortalidad (20-55%). Se describen las características clínicas, la letalidad y las variables de mal pronóstico en PVHIV con CM, en unidades de cuidados intensivos (UCI). Métodos: Estudio observacional y retrospectivo. Período 21/11/2006 a 24/05/2023. Población evaluada: 154 PVHIV adultos, admitidos en UCI con diagnóstico de CM. Los porcentajes y valores absolutos, fueron comparados mediante Chi-Cuadrado o test de Fisher y las medianas mediante test de Mann-Whitney. La asociación con mortalidad se evaluó por regresión logística. Se utilizó el programa SPSS 23.0. Un valor p<0.05 fue considerado significativo. Resultados: Los pacientes que fallecieron y los que sobrevivieron fueron comparables en edad y sexo (p>0.05). El análisis univariado, observó que un estado funcional y nutricional alterado, falta de tratamiento antirretroviral previo (TARV), CD4 <100 células/µl, APACHE II ≥ 13 y un score pronóstico de PVHIV ≥ 8 puntos, requerir ventilación mecánica (VM), sufrir insuficiencia respiratoria, renal, disfunción neurológica o sepsis, podrían estar asociados (p<0.05) con mortalidad. La regresión logística estableció que un estado funcional y nutricional alterado, un score pronóstico PVHIV ≥ 8, necesitar VM y sufrir sepsis serían variables independientes asociadas a mortalidad. Conclusión: Los resultados indican que el estado funcional y nutricional alterado, un score pronóstico PVHIV ≥ 8 puntos, requerir VM y sufrir sepsis al ingreso a UCI podrían servir como variables independientes para predecir un mayor riesgo de mortalidad.

ABSTRACT

Chikungunya virus is an Alphavirus, it belongs to the family Togaviridae and is transmitted by mosquitoes. It was first described during an outbreak in Southern Tanzania in 1952. It generally causes a febrile syndrome, accompanied by joint pain and arthritis, which is often debilitating and may persist for months or years. Its overall fatality rate is not high, around 0.1%. Atypical and severe cases have been reported. This virus has been detected in more than 110 countries globally. In Northeastern Brazil autochthonous cases have been diagnosed since September 2014. In Argentina, as well as in neighboring countries, cases were increasing during 2023, compared to the same periods in previous years. Until epidemiological week 26 of 2023, 1460 cases of chikungunya fever were reported in Argentina, 72% of them were considered of autochthonous transmission. The case of a 76-year-old female patient is here presented, her comorbidities were hypertension and aortic stenosis, who was admitted to intensive care unit due to septic shock with respiratory focus, interstitial pneumonia in X-ray pattern, and torpid evolution. She died within 24 hours of admission. A report of detectable Chikungunya virus by real-time polymerase chain reaction in real time was received post-mortem. This case results of clinical relevance due to its atypical presentation and the country low prevalence of severe infections by this virus. It warns of the need to include the differential diagnosis in cases with suspected diagnosis.


El virus Chikungunya es un Alfavirus de la familia Togaviridae trasmitido por mosquitos. Fue descrito por primera en un brote en el sur de Tanzania en 1952. Genera clásicamente un síndrome febril con poliartralgias y artritis, que pueden ser incapacitantes y tener una duración prolongada. La mortalidad global ronda en 0.1%. Existen reportes en la literatura de presentaciones atípicas y graves con compromiso de múltiples órganos. Se ha detectado la presencia del virus en más de 110 países. En Brasil, en la región noreste, se han hallado casos autóctonos desde septiembre de 2014. En Argentina y países limítrofes, se presentan casos en aumento durante 2023, con respecto a iguales periodos en años previos. Hasta la semana epidemiológica N° 26 del año 2023 se registraron en Argentina 1460 casos de fiebre chikungunya, considerándose autóctonos 72% de ellos. Se presenta el caso de una mujer de 76 años, con antecedentes de hipertensión arterial y estenosis aortica, admitida en terapia intensiva por shock séptico con foco respiratorio, con patrón de neumonía intersticial, evolución tórpida y óbito dentro de las 24 horas del ingreso. Se recibe postmorten el resultado detectable de virus Chikungunya por reacción en cadena de la polimerasa en tiempo real. Este caso, resulta de importancia clínica dada la presentación atípica del mismo y por la baja prevalencia nacional de infecciones graves por dicho virus, alerta sobre la necesidad de incluir el diagnóstico diferencial en los pacientes con sospecha diagnóstica.

ABSTRACT

Resumen El tétanos es causado por el Clostridium tetani, una bacteria ubicua que frente a condiciones de anaerobio sis puede sintetizar y liberar sus toxinas, responsables del cuadro clínico. Dado que es una bacteria que se encuentra en el suelo y en el tracto gastrointestinal de muchas especies, se trata de una enfermedad no erra dicable pero si controlable a través de la inmunización para la prevención. Las tasas de inmunización han disminuido en los últimos años, evento que se ha acentuado durante la COVID-19. Se presentan a continuación dos casos clínicos in gresados durante el año 2022. El primero es un hombre de 39 años cuya puerta de entrada fue una herida de arma de fuego conevolución favorable y el segundo caso se trata de una mujer de 83 años sin puerta de entrada clara quien falleció durante su internación en terapia intensiva. La importancia de esta presentación es mos trar la gravedad de la enfermedad, cuyavaloración es principalmente clínica y no debe escapar al algoritmo de diagnósticos diferenciales, acentuando que se debe instaurar el tratamiento de forma precoz o frente a la duda consultar con un centro especializado. Asímismo, es importante revisar las tasas de inmuni zación en nuestro país y los cambios que se presentaron durante la pandemia, teniendo en cuenta, como se ha expuesto previamente, se trata de una enfermedad in munoprevenible.


Abstract Tetanus is an infectious disease caused by a ubiqui tous bacterium Clostridium tetani, that synthesizes and releasesa potent neurotoxin under anaerobic conditions, which is responsible for the clinical manifestations. As it is found in soil contaminated with animal and human excreta, it is difficult to eradicate but it may be prevented by immunization. Immunization rate has decreased in the last years, especially during the COVID-19 pandemic. We report two cases of tetanus, attended during 2022. A 39-year-old man whose entry route was a gunshot wound and he was discharged from the intensive care unit (ICU) and a second case of an 83-year-old woman with unknown entry point, who died during her ICU stay. The cases reported highlight that it is a life-threatening disease, its diagnosis is mainly clinical and it should be in the algorithm of differential diagnoses. We emphasize about the prompt treatment administration or consulta tion to a specialized healthcare center. The importance of this presentation is to show the severity of the dis ease, whose assessment is mainly clinical and should not escape the algorithm of differential diagnoses, em phasizing that treatment should be instituted early or when in doubt consult a specialized center. In addition to this, it is important to check theimmunization rate in our country, especially during thepandemic, becauseit is a vaccine-pre ventable disease.

ABSTRACT

Introduction. Fungal infections in patients with COVID-19 was one of the most debated topics during the pandemic. Objectives. To analyze the clinical characteristics and evolution of people living with HIV/ AIDS and coinfection with cryptococcus and COVID-19 (group A) or without it (group B). Materials and methods. This is an analytical and retrospective study. We reviewed medical records of patients with meningeal cryptococcosis between April 2020 and May 2021. Results. We studied 65 people living with HIV/AIDS and with cryptococcosis infection diagnosed from April 2020 to May 2021. Fifteen patients with HIV/AIDS suffered from cryptococcosis and COVID-19, and out of these, 14 presented meningitis (group A), while 28 suffered from meningeal cryptococcosis, but did not have COVID-19 (group B). Conclusions. No statistically significant differences were observed between the two groups (A and B) considering: intracranial hypertension, presence of Cryptococcus antigens in cerebrospinal fluid, sensorium deterioration or mortality. The detection of Cryptococcus antigens in serum by lateral flow assay was highly effective to rapidly diagnose cryptococcosis in patients with HIV/AIDS who also developed COVID-19. Patients of both groups consulted for cryptoccocosis sometime after, in comparison with the pre-pandemic cases related to this infection.


Introducción. Las infecciones fúngicas en pacientes con COVID-19 fue uno de los temas más debatidos durante la pandemia. Objetivo. Analizar las características clínicas y la evolución de personas con VIH/SIDA que presentaron la asociación de criptococosis meníngea y COVID-19 (grupo A), y compararlas con aquellas personas con VIH/SIDA que padecieron criptococosis meníngea, pero sin infección de COVID-19 (grupo B). Materiales y métodos. Se realizó un estudio analítico y retrospectivo en el que se revisaron las historias clínicas de pacientes que padecieron criptococosis meníngea entre abril de 2020 y mayo de 2021. Resultados. Se estudiaron 65 pacientes con HIV/SIDA y con criptococosis, diagnosticados entre abril de 2020 y mayo de 2021 (63 habían desarrollado sida y 2 eran negativos para VIH). De estos, 15 de los pacientes con sida padecían criptococosis y COVID-19, y 14 presentaban meningitis (grupo A), mientras que 28 pacientes padecieron criptococosis meníngea, pero no tuvieron COVID-19 (grupo B). Conclusiones. No se observaron diferencias estadísticamente significativas, entre los dos grupos, respecto a la hipertensión intracraneal, la presencia de antígenos de criptoccoco en líquido cefalorraquídeo, el deterioro del sensorio o la mortalidad. La detección de antígenos de Cryptococcus en suero por ensayo de flujo lateral fue efectiva para diagnosticar rápidamente criptococosis en personas con VIH/sida y con infección de COVID-19. Se observó que los pacientes de ambos grupos consultaron tarde por criptococosis en comparación con los casos prepandémicos de esta infección.

ABSTRACT

El virus de la viruela símica es un orthopoxvirus de características zoonóticas endémico en las regiones de África Central y África Occidental, donde causa brotes desde 1970. En las últimas décadas se registró un aumento exponencial de casos, probablemente asociado a la disminución en la inmunidad conferida por la vacuna antivariólica, discontinuada luego de la erradicación de la viruela. En los últimos años se registraron casos esporádicos fuera del continente africano, siempre relacionados epidemiológicamente a la permanencia en áreas endémicas o contacto con animales infectados. Desde el 13 de mayo de 2022 se encuentra en curso el mayor brote de viruela símica registrado fuera de las áreas endémicas de África, con casos en los cinco continentes. La extensión, el impacto y la duración del brote permanecen aún inciertos.


Monkeypox virus is an orthopoxvirus with zoonotic characteristics endemic in Central and West Africa regions, where it has caused outbreaks since 1970. An exponential increase in cases has been registered in the last decades, probably associated with a decrease in the immunity conferred by the smallpox vaccine, discontinued after smallpox eradication. In recent years, sporadic cases have been reported outside the African continent, always epidemiologically related to permanence in endemic areas or contact with infected animals. Since May 13, 2022, the largest monkeypox outbreak ever reported outside Africa endemic areas, with cases on the five continents, is unfolding. The extent, impact and duration of this outbreak still remain uncertain

ABSTRACT

BACKGROUND: The role of oral vitamin D3 supplementation for hospitalized patients with COVID-19 remains to be determined. The study was aimed to evaluate whether vitamin D3 supplementation could prevent respiratory worsening among hospitalized patients with COVID-19. METHODS AND FINDINGS: We designed a multicentre, randomized, double-blind, sequential, placebo-controlled clinical trial. The study was conducted in 17 second and third level hospitals, located in four provinces of Argentina, from 14 August 2020 to 22 June 2021. We enrolled 218 adult patients, hospitalized in general wards with SARS-CoV-2 confirmed infection, mild-to-moderate COVID-19 and risk factors for disease progression. Participants were randomized to a single oral dose of 500 000 IU of vitamin D3 or matching placebo. Randomization ratio was 1:1, with permuted blocks and stratified for study site, diabetes and age (≤60 vs >60 years). The primary outcome was the change in the respiratory Sepsis related Organ Failure Assessment score between baseline and the highest value recorded up to day 7. Secondary outcomes included the length of hospital stay; intensive care unit admission; and in-hospital mortality. Overall, 115 participants were assigned to vitamin D3 and 105 to placebo (mean [SD] age, 59.1 [10.7] years; 103 [47.2%] women). There were no significant differences in the primary outcome between groups (median [IQR] 0.0 [0.0-1.0] vs 0.0 [0.0-1.0], for vitamin D3 and placebo, respectively; p = 0.925). Median [IQR] length of hospital stay was not significantly different between vitamin D3 group (6.0 [4.0-9.0] days) and placebo group (6.0 [4.0-10.0] days; p = 0.632). There were no significant differences for intensive care unit admissions (7.8% vs 10.7%; RR 0.73; 95% CI 0.32 to 1.70; p = 0.622), or in-hospital mortality (4.3% vs 1.9%; RR 2.24; 95% CI 0.44 to 11.29; p = 0.451). There were no significant differences in serious adverse events (vitamin D3 = 14.8%, placebo = 11.7%). CONCLUSIONS: Among hospitalized patients with mild-to-moderate COVID-19 and risk factors, a single high oral dose of vitamin D3 as compared with placebo, did not prevent the respiratory worsening.

ABSTRACT

Hantavirus cardiopulmonary syndrome is an emerging zoonosis in Argentina, which has low incidence but high death rates. No specific pharmacological therapy is available and symptomatic therapy is the only current alternative. This article presents the pathogenesis of hantavirus cardiopulmonary syndrome through a review of clinical experiences in neighbor South American countries, mainly Chile, and the experience acquired at the Infectious Diseases Hospital Francisco Javier Muñiz, Buenos Aires, Argentina. The role of early corticosteroid therapy is discussed taking into account that there is insufficient evidence favoring its use in the hantavirus cardiopulmonary syndrome.


El síndrome cardiopulmonar por hantavirus es una zoonosis emergente en la Argentina, que presenta baja incidencia, pero elevada mortalidad. No existe tratamiento farmacológico especifico y la única alternativa actual es la terapia de apoyo. En este artículo se expone la patogenia del síndrome cardiopulmonar por hantavirus a través de la revisión de las experiencias clínicas de otros países de Sudamérica, en particular Chile, y la adquirida en el Hospital de Infecciosas Francisco Javier Muñiz de Buenos Aires, Argentina. Se discute sobre la administración temprana de corticoides en este síndrome, teniendo en cuenta que la evidencia a favor de su uso es insuficiente.

ABSTRACT

Chagas disease (ChD), caused by the protozoan Trypanosoma cruzi, is an endemic anthropozoonosis in Latin America, linked to deficients socio-economic and cultural aspects and is considered one of the neglected tropical diseases. We report a fatal case of Chagas disease reactivation with central nervous system involvement in a patient with HIV infection, whose diagnosis was confirmed by positive PCR (polymerase chain reaction) test of blood, with treatment response efficiency with benznidazol and management and etiologic treatment was difficult due to limited number of antitrypanosomal drugs and the occurrence of frequent and serious adverse effects.

La enfermedad de Chagas, causada por el protozoo Trypanosoma cruzi, es una antropo-zoonosis endémica en Latinoamérica, vinculada con aspectos socio-económico-culturales deficitarios y considerada una de las enfermedades desatendidas. Presentamos un caso fatal de una reactivación de la enfermedad de Chagas con afectación del sistema nervioso central en un paciente con infección por VIH. El diagnóstico se confirmó por reacción de polimerasa en cadena (RPC) positiva en sangre. Tuvo una buena respuesta al tratamiento con benznidazol. Las dificultades en el manejo del tratamiento etiológico se debieron al número limitado de medicamentos antitripanosomiásicos y la aparición de efectos adversos graves.
