Propuesta para superar las dificultades diagnósticas de las úlceras de Lipschütz, a propósito de un caso / Proposal to overcome the diagnostic difficulties of Lipschütz ulcers. A case study

La úlcera de Lipschütz, llamada así por el dermatólogo austríaco que la describió por primera vez en 1913, es una patología poco frecuente que se debe considerar en el diagnóstico diferencial de las úlceras genitales de mujeres con o sin vida sexual activa. Es precedida por síntomas sistémicos típicos de una viriasis y tiene buen pronóstico por su curso autolimitado. La falta de conocimiento de esta entidad (sobre todo en su etiopatogenia), su baja incidencia y la ausencia de criterios diagnósticos claros contribuyen a que siga siendo infradiagnosticada. Con el presente trabajo, pretendemos minimizar este problema al crear un método diagnóstico simplificado que a su vez permite una clasificación pionera.(AU)

Lipschütz ulcer is named after the Austrian dermatologist who first reported this in 1913. It’s a rare pathology that should be considered in the differential diagnosis of genital ulcers in women with or without an active sexual life. It’s preceded by systemic symptoms typical of a viral infection and it has a good prognosis as it’s self-limited. This entity is underdiagnosed due to limited knowledge (especially in aetiopathogenesis), its low incidence and because there are no clear diagnostic criteria. We tried to improve this problem by creating a simplified diagnostic method and a pioneer classification.(AU)

Analysis of selective screening for congenital cytomegalovirus in a secondary hospital: Problems and solutions.

Universal hearing screening offers unique possibilities for detection of congenital deafness as a consequence of congenital cytomegalovirus (CMVc) infection, so its selective study in the case of a failed test could be a non-negligible screening opportunity while other guidelines covering the possibility of universal screening are adopted. The aim of this study is to analyse the possibility of selective screening for CMVc after an altered hearing test in a regional hospital. During the period studied, the results obtained were unsatisfactory, especially in children born outside the hospital of residence, showing an excessive delay in hearing screening in many cases and in the few cases where CMVc screening could be performed, only 30% had the test ordered in a timely manner. The reasons for this are varied and the solution is to include selective screening for CMVc in the hearing screening programme. This implies shortening the timing of the hearing screening protocol to allow CMVc testing in saliva or urine (preferably) before 21 days of age and providing screening programmes with the necessary staff and time to perform it properly.

Catarata congênita nas infecções intrauterinas mais comuns (STORCH): revisão de literatura / Congenital cataract in the most common intrauterine infections (STORCH): a review of the literature

RESUMO Objetivo: O objetivo deste estudo foi revisar os aspectos clínicos e patológicos da catarata congênita secundária às infecções por sífilis, toxoplasmose, rubéola, citomegalovírus e herpes simples. Métodos: Trata-se de uma revisão de literatura, na qual foram incluídos artigos de periódicos indexados às bases de dados PubMed®, Cochrane, Lilacs, Embase e SciELO de 2010 a 2023. Resultados: Foram encontrados 45 artigos, e, após seleção, restaram 9 artigos. Além disso, foram adicionados artigos para enriquecer a discussão. A infecção por sífilis está relacionada a alterações corneanas. O citomegalovírus e a toxoplasmose estão relacionados com a coriorretinite e/ou microftalmia. A rubéola é responsável por causar catarata, glaucoma, microftalmia e retinite em sal e pimenta. Conclusão: Foram abordadas as principais etiologias infecciosas e seu quadro clínico na CC. O melhor tratamento para CC é cirúrgico associado a acompanhamento clínico, mas a prevenção é a maneira mais eficaz de combater a CC de etiologia infecciosa. O diagnóstico precoce e o tratamento efetivo previnem alterações e sequelas visuais irreversíveis. Nesse contexto, mostram-se importantes as ações de políticas públicas para o melhor desfecho clínico e melhor qualidade de vida.

ABSTRACT Objective: To review the clinical and pathological aspects of CC secondary to infections by syphilis, toxoplasmosis, rubella, cytomegalovirus, herpes simplex. Methods: This is a literature review. Articles from journals indexed to PubMed, COCHRANE, LILACS, EMBASE and SCIELO from 2010 to 2023 were included. Results: A total of 45 articles were found, which, after selection, remained in 9 articles. Some articles were included to enrich the discussion in this topic. The infection caused by syphilis is related to corneal changes. Cytomegalovirus and Toxoplasmosis due to chorioretinitis and/or microphthalmia. Rubella is responsible for causing cataracts, glaucoma, microphthalmia, and salt and pepper retinitis. Conclusion: The main infectious etiologies and their clinical status in CC were addressed. The best treatment for CC is surgery associated with clinical follow-up, but prevention is the most effective way to combat CC of infectious etiology. Early diagnosis and effective treatment prevent irreversible visual changes and sequelae. In this context, public policy actions are important for the best clinical outcome and better quality of life.

Infección congénita por citomegalovirus en neonatos muy bajo peso

Introducción: La infección congénita por el citomegalovirus en neonatos menores de 1500 gramos puede ser causa de morbilidad, mortalidad y discapacidad. Objetivo: Describir el comportamiento de la infección congénita por citomegalovirus en un servicio de neonatología. Métodos: Se realizó un estudio descriptivo y transversal con 61 neonatos. Se les realizó detección de citomegalovirus en la primera semana de vida en suero y orina, mediante reacción en cadena de la polimerasa, para determinar infección congénita. Se evaluaron variables perinatales en todos los neonatos, así como elementos clínicos y resultados de exámenes complementarios en los infectados. Resultados: La incidencia de infección congénita fue de un 10 % (6/61). El 5 % de los estudios fueron positivos (6/122). Ninguna muestra de orina resultó positiva (0/61) y en el 10 % de las muestras de suero (6/61) se detectó el genoma del virus. Se encontró asociación entre valoración nutricional al nacer e infección por citomegalovirus (p< 0,05). El 83 % de los neonatos infectados presentaron algún signo clínico y el síndrome de dificultad respiratoria fue el más frecuente (67 %). En todos los neonatos con infección congénita el ultrasonido cerebral fue normal y en el 33 % se detectó retinopatía de la prematuridad en el fondo de ojo. Conclusiones: La incidencia de infección congénita por citomegalovirus es alta en este grupo de riesgo. Los signos clínicos encontrados y los resultados del fondo de ojo en neonatos con infección congénita se relacionaron con la prematuridad y la valoración nutricional de hipotrófico se asoció con esta infección.

Introduction: Congenital cytomegalovirus infection in neonates weighing less than 1500 grams can be a cause of morbidity, mortality, and disability. Objective: To describe the behavior of congenital cytomegalovirus infection in a neonatal service. Methods: A descriptive and cross-sectional study was conducted with 61 neonates. Cytomegalovirus was detected in the first week of life in serum and urine, by polymerase chain reaction, to determine congenital infection. Perinatal variables were evaluated in all neonates, as well as clinical elements and results of complementary examinations in infected infants. Results: The incidence of congenital infection was 10% (6/61). 5% of the studies were positive (6/122). No urine samples were positive (0/61) and the virus genome was detected in 10% of serum samples (6/61). An association was found between nutritional assessment at birth and cytomegalovirus infection (p < 0.05). A total of 83% of infected neonates had some clinical sign, with respiratory distress syndrome being the most common (67%). In all neonates with congenital infection, brain ultrasound was normal, and retinopathy of prematurity was detected in 33% of patients with fundus retinopathy. Conclusions: The incidence of congenital cytomegalovirus infection is high in this risk group. The clinical signs found and the results of the fundus in neonates with congenital infection were related to prematurity and the nutritional assessment of hypotrophic was associated with this infection.

Importancia del citomegalovirus congénito en el programa de cribado auditivo neonatal / Importance of congenital cytomegalovirus in the neonatal hearing screening program

Introducción En recién nacidos, la hipoacusia secundaria a una infección congénita por citomegalovirus (CMVc), pese a su baja prevalencia, puede generar un grave problema en el desarrollo personal y la integración social de los pacientes. Por ello, es importante incluir la determinación del ADN de CMV como herramienta del cribado neonatal. Materiales y métodos Hemos realizado un estudio retrospectivo de 5 años, mediante la descripción de las CMVc en la Comunidad Autónoma del País Vasco en los recién nacidos que no superaron el cribado auditivo en el programa de detección precoz de hipoacusia. Se describen los tiempos de detección, confirmación (incidencia) e intervención (tratamiento). Resultados De 18.782 sujetos estudiados, 58 (3 por cada 1.000 nacidos vivos) presentaron hipoacusia. De ellos, se confirmó CMVc en 4pacientes (una mujer y 3hombres).El tiempo promedio para el cribado auditivo fue de 6,5 días (DE:±3,69) y para detectar el CMV mediante reacción en cadena de la polimerasa en orina y saliva fue de 4,2 días (DE:±3,94).El tiempo para confirmar la hipoacusia mediante PEATC e intervención audiológica fue de 2,2 meses (DE:±0,957) y 5 meses (DE:±3,741), respectivamente. Se realizaron 4adaptaciones audioprotésicas y un implante coclear. Discusión y conclusión El cribado auditivo neonatal se ha consolidado como un buen programa de salud pública. La determinación del ADN viral permite un diagnóstico y tratamiento precoz, específico e interdisciplinar, en el que la otorrinolaringología tiene un papel fundamental. Nuestro estudio resalta la importancia de incluir la reacción en cadena de la polimerasa del CMV como herramienta de cribado universal. (AU)

Introduction In newborns, hearing loss secondary to congenital cytomegalovirus (CMVc) infection, despite its low prevalence, can cause a serious problem in the personal development and social integration of patients. Therefore, it is important to include the determination of CMV DNA as a neonatal screening tool. Materials and methods We have carried out a 5-year retrospective study, by describing the CMVc in the Autonomous Community of the Basque Country (Spain) in newborns who did not pass the hearing screening in the early hearing loss detection program. The times of detection, confirmation (incidence) and intervention (treatment) are described. Results Of 18,782 subjects studied, 58 (3 per 1,000 live births) presented hearing loss. Of these, CMVc is guaranteed in 4patients (one woman and 3men). The mean time to hearing screening was 6.5 days (SD: ±3.69) and to detect CMV by polymerase chain reaction in urine and saliva was 4.2 days (SD: ±3.94). Time to confirm hearing loss by BAEP and audiological intervention 2.2 (SD: ±0.957) and 5 months (SD: ±3.741), respectively. Four hearing aid adaptations and one cochlear implant were performed. Discussion and conclusion Neonatal hearing screening has established itself as a good public health program. The determination of viral DNA allows an early, specific and interdisciplinary diagnosis and treatment, in which otorhinolaryngology plays a fundamental role. Our study highlights the importance of including CMV polymerase chain reaction as a universal screening tool. (AU)

In vitro assessment of the combined effect of letermovir and sirolimus on cytomegalovirus replication / Evaluación in vitro del efecto combinado de letermovir y sirolimus en la replicación de citomegalovirus

Introduction. Letermovir (LMV) is used for prophy laxis of cytomegalovirus (CMV) reactivation and end-or gan disease in adult CMV-seropositive allogeneic hemato poietic stem cell transplant recipients (allo-HSCT). In turn, sirolimus (SLM) which displays in vitro anti-CMV activity, is frequently employed for prophylaxis of Graft vs. Host disease in allo-HSCT. Here, we aimed at assessing whether LMV and SLM used in combination may act synergistically in vitro on inhibiting CMV replication. Material and methods. The antiviral activity of LMV and SLM alone or in combination was evaluated by a checkerboard assay, using ARPE-19 cells infected with CMV strain BADrUL131-Y. LMV and SLM were used at con centrations ranging from 24 nM to 0.38 nM and 16 nM to 0.06 nM, respectively. Results. The mean EC50 for LMV and SLM was 2.44 nM (95% CI, 1.66-3.60) and 1.40 nM (95% CI, 0.41-4.74), re spective. LMV and SLM interaction yielded mainly additive effects over the range of concentrations tested. Conclusion. The additive nature of the combination of LMV and SLM against CMV may have relevant clini cal implications in management of CMV infection in al lo-HSCT recipients undergoing prophylaxis with LMV (AU)

Introducción. Letermovir (LMV) se utiliza para la pro filaxis de la reactivación de la infección y de la enfermedad orgánica por citomegalovirus (CMV) en adultos receptores de trasplante alogénico de células madre hematopoyéticas (alo TPH) en pacientes seropositivos para CMV. A su vez, sirolimus (SLM), que muestra actividad anti-CMV in vitro, se usa con fre cuencia para la profilaxis de la enfermedad de injerto contra huésped en alo-TPH. Nuestro objetivo fue evaluar si LMV y SLM utilizados en combinación pueden actuar sinérgicamente in vi tro en inhibir la replicación del CMV. Material y métodos. La actividad antiviral de LMV y SLM individualmente o en combinación se evaluó mediante un en sayo de tablero de ajedrez, utilizando células ARPE-19 infec tadas con la cepa BADrUL131-Y de CMV. Se utilizaron LMV y SLM en concentraciones que variaron entre 24 nM y 0,38 nM y entre 16 nM y 0,06 nM, respectivamente. Resultados. La EC50 media para LMV y SLM fue de 2,44 nM (IC del 95 %, 1,66-3,60) y 1,40 nM (IC del 95 %, 0,41-4,74), respectivamente. La interacción LMV y SLM produjo principal mente efectos aditivos en el rango de concentraciones ensa yadas. Conclusión. La naturaleza aditiva de la combinación de LMV y SLM frente a CMV puede tener implicaciones clínicas re levantes en el tratamiento de la infección por CMV en alo-TPH que reciben profilaxis con LMV (AU)

Letermovir para prevención de la infección por citomegalovirus en receptores de trasplante alogénico de progenitores hematopoyéticos

Introducción: La infección por citomegalovirus (CMV) sigue siendo la infección con relevancia clínica más frecuente luego del trasplante alogénico de progenitores hematopoyéticos (TPHa), presentando alta morbilidad y mortalidad. Por este motivo, es importante implementar estrategias de prevención para reducir la frecuencia de la infección por CMV. Objetivo: Describir la frecuencia de infección, infección clínicamente significativa (ICS) y enfermedad por CMV en pacientes seropositivos que recibieron un TPHa y profilaxis primaria con letermovir. Pacientes y Métodos: Estudio descriptivo de cohorte longitudinal, en pacientes con TPHa seropositivos para CMV que recibieron profilaxis primaria con letermovir hasta el día 100 posTPH. Resultados: Se incluyeron 25 pacientes adultos con una mediana de edad de 41 años, el 44% fue de donante no relacionado y 36% de donante haploidéntico. Ochenta por ciento tenía tres o más factores de riesgo para infección por CMV y a 52% se le estratificó como de alto riesgo para enfermedad por CMV. La profilaxis con letermovir tuvo una mediana de duración de 97 días. Durante los 100 días pos-TPH, 20% de los pacientes presentaron infección por CMV, con carga viral plasmática detectable no cuantificable, que se negativizó en el siguiente control semanal sin discontinuación del letermovir. Ningún paciente presentó ICS ni enfermedad por CMV durante este período. Conclusión: La profilaxis con letermovir fue efectiva para prevenir la ICS y la enfermedad por CMV.

Background: Cytomegalovirus (CMV) infection remains the most common clinically significant infection after allogeneic stem cell transplantation (aSCT), with a high morbidity and mortality rate. In order to reduce its frequency, prevention strategies should be implemented. Aim: To describe the frequency of infection, clinically significant infection (CSI) and CMV disease in seropositive patients who received aSCT and primary prophylaxis with letermovir. Methods: Longitudinal descriptive cohort study in seropositive patients who received aSCT and primary prophylaxis with letermovir until day 100 post-SCT. Results: Twenty-five adult patients with a median age of 41 years were included; 44% were unrelated donors, and 36% were haploidentical donors. Eighty percent had three or more risk factors for CMV infection, and 52% were stratified as high risk for CMV disease. Letermovir prophylaxis had a median duration of 97 days. Twenty percent of the patients developed CMV infection through day 100 post-SCT, with detectable non-quantifiable CMV viral load in plasma. This became negative in the following weekly control without discontinuation of letermovir. No patient developed CSI or CMV organ disease during this period. Conclusion: Letermovir prophylaxis proved to be effective in preventing CSI and CMV disease.

Villitis crónica granulomatosa asociada a citomegalovirus. Un hallazgo inusual que induce a confusión. A propósito de un caso / Chronic granulomatous villitis due to cytomegalovirus. An unusual finding that may cause confusion. A case report

La villitis crónica por citomegalovirus (CMV) cursa típicamente con inflamación de células plasmáticas. La reacción granulomatosa en el árbol velloso placentario está generalmente causada por patógenos distintos del CMV, como el toxoplasma o la rubéola. Se presenta el caso de una paciente con un feto sin latido cardíaco en la semana 20de embarazo. El estudio de su placenta reveló una villitis crónica por CMV, en la que se observa una reacción granulomatosa, en lugar de la típica inflamación de células plasmáticas.(AU)

Chronic cytomegalovirus (CMV) villitis typically causes inflammation with predominance of plasma cells. The granulomatous reaction in the chorionic villi is usually caused by pathogens other than CMV, such as toxoplasma or rubella. We present a case of a pregnant woman presenting with foetal death in the twentieth week of gestation. The study of the placenta revealed chronic CMV villitis with a granulomatous reaction, rather than the more common plasma cell inflammation.(AU)

Seroprevalence of Toxoplasma, Rubella and Cytomegalovirus in Women of Fertility Age in Our Region

Objective: Toxoplasma gondii (T. gondii), Rubella and Cytomegalovirus (CMV) infections can cause severe morbidity in the fetus when transmissed during pregnancy. In our study, it was aimed to examine the seropositivity rates for T. gondii, Rubella and CMV infections in women of childbearing age who applied to our hospital. Methods: Anti-Toxoplasma IgG, anti-Toxoplasma IgM, anti-Rubella IgG, anti-Rubella IgM, anti-CMV IgG and anti-CMV were studied in women of childbearing age (18-49 years old) who applied to our hospital's outpatient clinics between January 2018 and December 2020. The tests were performed in our microbiology laboratory using the ELISA method on Architect i2000 (Abbott, USA) and COBAS e601 (Roche, Germany) devices. Results: As a result of the data obtained, the percentages of IgM and IgG positivity for anti-Toxoplasma were calculated as 1.4% and 30.9%, respectively. Anti-Rubella IgM positivity was 0.7%, anti-Rubella IgG positivity was 91%, anti-CMV IgG positivity was 98.8%, and anti-CMV IgM positivity was 2%. Conclusion: Having its own seroprevalence for each region has is important in terms of planning pregnancy screenings. The seropositivity rates in our region are in line with other studies in the country. Since CMV seropositivity is very high in the population and there is no effective treatment or vaccine, screening may not be not necessary. T. gondii and Rubella screenings can be recommended due to the lower immunity rates and the availability of vaccine and treatment options.

Enfermedad por citomegalovirus en los pacientes inmunodeprimidos por glomerulonefritis necrosante pauciinmune / Cytomegalovirus disease in immunosuppressed patients with necrotizing pauci-immune glomerulonephritis

Introducción: La afectación renal por glomerulonefritis necrosante pauciinmune (GNPI) asociada a vasculitis de pequeño vaso requiere tratamiento inmunodepresor, cuyos efectos secundarios incluyen un mayor riesgo de procesos infecciosos, como la enfermedad por citomegalovirus (CMV), aunque no hay recomendaciones sobre su manejo en las guías de práctica clínica (GPC).ObjetivoEstudiar la incidencia de enfermedad por CMV y sus determinantes.Pacientes y métodosPacientes con diagnóstico histológico de GNPI en los últimos 10 años, determinando la carga viral de CMV y analizando los determinantes de su concurrencia.ResultadosSe realizaron 44 biopsias durante el periodo de estudio. Del total, 11 pacientes (25%) desarrollaron enfermedad por CMV; todos habían recibido tratamiento inmunodepresor. Cuatro (30,8%) fallecieron durante el ingreso. Los factores determinantes de la enfermedad fueron la edad (por cada 10 años OR: 3,0, IC 95%: 1,0 a 8,9, p = 0,012) y la albúmina (por cada g/L OR: 0,8, IC 95%: 0,6 a 1,0, p = 0,012).ConclusionesLa incidencia de enfermedad por CMV en pacientes inmunodeprimidos por GNPI es alta, con alta mortalidad. Sería necesario incluir estrategias en las GPC para prevenir su desarrollo. (AU)

Introduction: Renal involvement due to necrotizing pauci-immune glomerulonephritis (PIGN) associated with small vessel vasculitis requires the use of immunosuppressive. Associated side effects include an increased risk of infectious processes, such as cytomegalovirus (CMV) disease; therefore, there are no recommendations on its management in the various clinical practice guidelines (CPG).ObjectiveTo study the incidence of CMV disease and its determinants.Patients and methodsPatients with histological diagnosis of necrotizing pauci-immune glomerulonephritis in the last 10 years, who were determined the viral load of CMV, analyzing the determinants of its occurrence.ResultsForty-four biopsies were performed during the study period. Eleven patients (25%) developed CMV disease; all had received immunosuppressive treatment. Four (30.8%) died during admission. The determinants of CMV disease were age (for every 10 years OR: 3.0, 95% CI: 1.0-8.9, p = 0.012), and plasma albumin (for each g/L OR: 0.8, 95% CI: 0.6-1.0, p = 0.012).ConclusionsThe incidence of CMV disease in immunocompromised patients due to PIGN is high, with high mortality. It would be necessary to include strategies in the CPGs to prevent it. (AU)

Cytomegalovirus reactivation in patients diagnosed with severe COVID-19: A point prevalence study in a general hospital / Reactivación de citomegalovirus en pacientes diagnosticados de COVID-19 grave: Un estudio de prevalencia en un hospital general

Purpose: To determine the prevalence of CMV reactivation in a population admitted for severe COVID-19 to a general hospital. Methods: Point prevalence study in all hospitalized patients with severe COVID-19 (admitted either to general wards or ICU). Determination of the presence of CMV DNA in circulating blood. COVID-19 was confirmed in patients with compatible clinical manifestations, usually with pneumonia and a positive nasopharyngeal PCR test. Results: We included 140 hospitalized patients with COVID-19 who consented to participate. A total of 16 patients (11.42%), had circulating CMV-DNA in peripheral blood at the time of the study. Patients with positive CMV viral load were mainly ICU patients (11/37 -29,7%) and only 5/103 cases (4,85%) were hospitalized into general wards. The accumulated doses of corticosteroids (prednisone equivalents) in the study day were (median and IQR) 987.50 mg (396.87-2,454.68) and 187.50 mg (75.00-818.12) respectively in CMV positive and negative patients (p < 0.001). A significant proportion of CMV positive patients were discovered because of the study and were clinically unsuspected by their physicians. The coinfected COVID-CMV positive population had a higher risk of accumulated secondary nosocomially-acquired infections and a worse prognosis. Conclusion: CMV reactivation should be systematically searched in patients in COVID-19 cases admitted to the ICU. (AU)

Objetivo: Determinar la prevalencia de reactivación del CMV en una población ingresada por COVID-19 grave en un hospital general. Métodos: Estudio de prevalencia en todos los pacientes hospitalizados con COVID-19 (ingresados en salas generales o UCI). Determinación de la presencia de ADN de CMV en sangre. COVID-19 fue confirmado en pacientes con manifestaciones clínicas compatibles, generalmente con neumonía y una prueba de PCR nasofaríngea positiva. Resultados: Se incluyeron 140 pacientes hospitalizados con COVID-19 que firmaron el consentimiento. Un total de 16 pacientes (11,42%), tenían ADN-CMV circulante en sangre periférica en el momento del estudio. Los pacientes con carga viral CMV positiva eran principalmente pacientes de UCI 11/37 (29,7%) y solo 5/103 casos (4,85%) fueron hospitalizados en salas generaleres. Las dosis acumuladas de corticoides (equivalentes de prednisona), en el día del estudio fueron (mediana y RIQ) 987,50 mg (396,87-2.454,68) y 187,50 mg (75,00-818,12) respectivamente en pacientes con CMV positivo y negativo (p< 0,001). Una proporción significativa de pacientes con CMV positivos fueron descubiertos debido al estudio y fueron clínicamente insospechados por sus médicos. La población coinfectada con COVID-CMV positivo tuvo un mayor riesgo de infecciones nosocomiales secundarias acumuladas y un peor pronóstico. Conclusión: La reactivación de CMV debe buscarse sistemáticamente en pacientes con COVID-19 ingresados en la UCI. (AU)

"Blueberry muffin": Manifestación atípica de una infección congénita frecuente

El síndrome "blueberry muffin" es una dermatosis maculopapular eritematoviolácea como resultado de una hematopoyesis extramedular. Se ha asociado con infecciones del espectro TORCH y causas no infecciosas. Presentamos el caso de un recién nacido pretérmino, quien desde el control prenatal presentó una ecografía con signos sugerentes de infección congénita por citomegalovirus (microcefalia, ventriculomegalia y calcificaciones intracerebrales). Al examen físico presentaba una dermatosis macular violácea compatible con síndrome "blueberry muffin". Se detectó carga viral de citomegalovirus en orina (81,200 copias/ml) e inició tratamiento con ganciclovir, con desenlace fatal. La infección congénita por CMV debe considerarse ante el síndrome "blueberry muffin"; el adecuado abordaje diagnóstico debe ser oportuno y debe incluir antecedentes maternos y perinatales, así como estudios serológicos para infecciones por TORCH con el fin del inicio precoz de tratamiento para evitar complicaciones y secuelas.

Blueberry muffin syndrome is characterized by an erythematousviolaceous maculopapular dermatosis due to extramedullary hematopoiesis. This entity has been associated with TORCH spectrum infections and noninfectious causes. We present the case of a preterm newborn, who since the prenatal control gave an ultrasound with data suggestive of congenital infection by cytomegalovirus (microcephaly, ventriculomegaly, intracerebral calcifications). On physical examination, he presented a violaceous macular dermatosis compatible with blueberry muffin syndrome. Cytomegalovirus viral load was detected in urine (81,200 copies/ml), with fatal outcome. Congenital cytomegalovirus infection should be considered in the presence of a blueberry muffin syndrome; an adequate diagnostic approach that includes maternal and perinatal history is essential, as well as serology studies for diseases of the TORCH spectrum in order to start early with treatment and avoid major comorbidities.

[Cytomegalovirus reactivation in patients with immune-mediated gastritis]. / Reactivación de citomegalovirus en pacientes con gastritis inmunomediada.

INTRODUCTION: Reactivation of cytomegalovirus can complicate the evolution of patients with gastritis induced by immune checkpoint inhibitors. METHODS: The experience in our center is described and a review of the literature is performed. RESULTS: A case of severe gastritis induced by treatment with a programmed cell death receptor-1 (anti-PD1) inhibitor, associated with reactivation of cytomegalovirus (CMV) is described. In the systematic review, we identified 5 cases of immune-related gastritis associated with CMV reactivation. Ganciclovir treatment contributed to clinical improvement in most patients. CONCLUSION: The early identification of a CMV infection in patients with severe or refractory immune-related gastritis will allow the initiation of targeted treatment, and may avoid increasing immunosuppressive therapy.

Coste efectividad de la estrategia de cribado de citomegalovirus en recién nacidos mayores de 34 semanas de bajo peso para la edad gestacional / Cost-effectiveness of a cytomegalovirus screening strategy in neonates born after 34 weeks small for gestational age

Introducción: El citomegalovirus (CMV) es una de las infecciones congénitas más frecuentes, con una prevalencia del 0,3-2,4%. En España, al no formar parte del cribado gestacional, se realiza screening de los recién nacidos con factores de riesgo y, en muchos centros, de los que presentan bajo peso para la edad gestacional (BPEG). Para ello se realiza, generalmente, determinación de Polymerase Chain Reaction (PCR) del virus en orina y/o ecografía transfontanelar en busca de imágenes compatibles. El objetivo del estudio es evaluar el rendimiento de la PCR de CMV en orina y ecografía transfontanelar, en recién nacidos >34 semanas asintomáticos, sin factores de riesgo, con BPEG. El objetivo secundario es evaluar el coste-efectividad. Material y métodos: Estudio observacional, descriptivo y retrospectivo, entre enero y diciembre de 2019, en un hospital de tercer nivel (IIIC). Incluye recién nacidos >34 semanas, sin factores de riesgo con BPEG, con PCR de CMV en orina y/o ecografía transfontanelar realizada. (AU)

Introduction: Infection by cytomegalovirus (CMV) is one of the most common congenital infections, with a global prevalence of 0.3%-2.4%. In Spain, CMV screening is not performed during pregnancy, but rather in neonates with risk factors, and, in many hospitals, in those born small for gestational age (SGA). Screening is usually performed by measurement of the viral load in urine by polymerase chain reaction (PCR) and/or head ultrasound in search of compatible features. The aim of the study was to assess the yield of the CMV PCR test in urine and head ultrasound examination in asymptomatic neonates born SGA after 34 weeks’ gestation. The secondary objective was to assess the cost-effectiveness of this strategy. Design and methods: We conducted an observational and retrospective study between January and December 2019 in a tertiary care hospital. It included neonates delivered after 34 weeks, SGA and without additional risk factors assessed with a CMV PCR test in urine and/or head ultrasound. (AU)

Cytomegalovirus Infection-related Immune Thrombocytopenia: A Case Report / Púrpura Trombocitopênica Imune Associada à Infecção por Citomegalovírus: Relato de Caso

Immune thrombocytopenia (ITP) is an acquired cause of thrombocytopenia characterized by the presence of autoantibodies against platelets. It may be primary or secondary to several conditions. We present the case of a 63-year-old woman with a diagnosis of immune thrombocytopenia refractory to conventional therapy. After she was tested for secondary causes of ITP, a diagnosis of acute cytomegalovirus (CMV) infection was made. She was treated with ganciclovir and presented normalization of platelet count. CMV-related Immune Thrombocytopenia should always be considered in certain cases of refractory ITP. If the diagnosis of ITP secondary to acute CMV infection is made, specific antiviral therapy with ganciclovir should be considered. In these cases, immunosuppressive agents, such as steroids, may worsen the ITP and should be tapered or withdrawn as rapidly as feasible.

A Púrpura Trombocitopênica Imune (PTI) é uma causa de trombocitopenia adquirida caracterizada pela presença de autoanticorpos contra plaquetas. A doença pode ser primária ou secundária a diversas condições. Apresentamos o caso de uma mulher de 63 anos com diagnóstico de PTI refratária à terapêutica convencional. A investigação de causas secundárias evidenciou infecção aguda por citomegalovírus (CMV). A paciente foi tratada com ganciclovir e evoluiu com normalização no nível de plaquetas. A PTI relacionada ao CMV deve sempre ser investigada em pacientes com PTI refratária, sendo a terapia antiviral específica com ganciclovir o tratamento de escolha. Nestes casos, os agentes imunossupressores, como os corticosteroides, podem piorar a PTI e devem ser reduzidos gradualmente ou retirados o mais rapidamente possível.

[Cytomegalovirus disease in immunosuppressed patients with necrotizing pauci-immune glomerulonephritis]. / Enfermedad por citomegalovirus en los pacientes inmunodeprimidos por glomerulonefritis necrosante pauciinmune.

INTRODUCTION: Renal involvement due to necrotizing pauci-immune glomerulonephritis (PIGN) associated with small vessel vasculitis requires the use of immunosuppressive. Associated side effects include an increased risk of infectious processes, such as cytomegalovirus (CMV) disease; therefore, there are no recommendations on its management in the various clinical practice guidelines (CPG). OBJECTIVE: To study the incidence of CMV disease and its determinants. PATIENTS AND METHODS: Patients with histological diagnosis of necrotizing pauci-immune glomerulonephritis in the last 10 years, who were determined the viral load of CMV, analyzing the determinants of its occurrence. RESULTS: Forty-four biopsies were performed during the study period. Eleven patients (25%) developed CMV disease; all had received immunosuppressive treatment. Four (30.8%) died during admission. The determinants of CMV disease were age (for every 10 years OR: 3.0, 95% CI: 1.0-8.9, p = 0.012), and plasma albumin (for each g/L OR: 0.8, 95% CI: 0.6-1.0, p = 0.012). CONCLUSIONS: The incidence of CMV disease in immunocompromised patients due to PIGN is high, with high mortality. It would be necessary to include strategies in the CPGs to prevent it.

Cost-effectiveness of a cytomegalovirus screening strategy in neonates born after 34 weeks small for gestational age.

INTRODUCTION: Infection by cytomegalovirus (CMV) is one of the most common congenital infections, with a global prevalence of 0.3%-2.4%. In Spain, CMV screening is not performed during pregnancy, but rather in neonates with risk factors, and, in many hospitals, in those born small for gestational age (SGA). Screening is usually performed by measurement of the viral load in urine by polymerase chain reaction (PCR) and/or head ultrasound in search of compatible features. The aim of the study was to assess the yield of the CMV PCR test in urine and head ultrasound examination in asymptomatic neonates born SGA after 34 weeks' gestation. The secondary objective was to assess the cost-effectiveness of this strategy. DESIGN AND METHODS: We conducted an observational and retrospective study between January and December 2019 in a tertiary care hospital. It included neonates delivered after 34 weeks, SGA and without additional risk factors assessed with a CMV PCR test in urine and/or head ultrasound. RESULTS: The sample included 259 patients. It was divided in 2 groups: group 1, patients with a head circumference, weight and length below the 10th percentile (53 patients; 20.5%), and group 2, patients in whom only the weight was below the 10th percentile (206 patients; 79.5%). The incidence of late preterm birth, twin pregnancy, neonatal admission and exposure to illicit drugs during gestation was higher in group 1. A total of 186 urine PCR tests and 223 head ultrasounds were performed overall, and both tests were performed more frequently in group 1 (P=.002). There was only 1 positive CMV PCR test result in the sample (0.54%), corresponding to a patient in group 2 with no abnormal sonographic findings who remained asymptomatic throughout the follow-up. Two head ultrasound examinations yielded abnormal findings, in both cases unrelated to congenital CMV infection. We performed a cost-effectiveness analysis and determined that the cumulative cost of head ultrasound examinations and urine CMV PCR tests in our sample amounted to Є17 000 for the detection of a single asymptomatic positive case. CONCLUSION: In our population, screening for congenital CMV infection in asymptomatic late preterm and term newborns whose only risk factor is SGA does not seem to be cost effective. It would be necessary to expand the sample to other populations.

Reactivación de citomegalovirus en pacientes críticos con infección por COVID-19 / Cytomegalovirus reactivation in critically ill patients with COVID-19 infection

Introducción: Existe bastante evidencia sobre la reactivación del citomegalovirus (CMV) en pacientes críticos y se ha planteado que pueda ser una de las coinfecciones que puedan aumentar la morbimortalidad en pacientes con infección severa por COVID-19. Por ello, se plantea un estudio para analizar las características de los pacientes COVID-19 que recibieron tratamiento anticitomegalovirus en la Unidad de Ciudados Intensivos (UCI). Material y métodos: Estudio multidisciplinar, observacional, retrospectivo, unicéntrico que incluyó todos los pacientes con COVID-19 en UCI que fueron tratados con ganciclovir o foscarnet entre marzo-2020 y abril-2021 en un hospital terciario. Variables: demográficas, relacionadas con el tratamiento para CMV, tratamiento recibido para COVID-19, estancia hospitalaria, mortalidad intrahospitalaria y al alta. Resultados: En el período de estudio, 26 pacientes críticos con COVID-19, recibieron algún tratamiento anticitomegalovirus (69,2% hombres, mediana de edad 64 años). En 15 (57,7%) se confirmó la reactivación microbiológicamente, y estos pacientes tuvieron estancias más prolongadas que los tratados sin confirmación. La mortalidad en el grupo tratado fue del 84,6% (80,0% en los que se confirmó reactivación), frente al 43,0% de mortalidad en el global de 300 pacientes COVID-19 que requirieron UCI en ese período. La tasa de infección demostrada de CMV fue del 5,0%. Conclusiones: Aunque existen publicaciones que sugieren un mayor riesgo de reactivación de CMV en pacientes COVID-19, la incidencia en nuestro estudio fue inferior a la descrita en pacientes críticos COVID. Hay que destacar la elevada mortalidad en los pacientes del estudio frente al global de pacientes atendidos en UCI por COVID-19. (AU)

Introduction: There is considerable evidence on the reactivation of cytomegalovirus (CMV) in critically ill patients and it has been suggested that it may be one of the co-infections that may increase morbidity and mortality in patients with severe COVID-19 infection. Therefore, a study was proposed to analyze the characteristics of COVID-19 patients who received anti-cytomegalovirus treatment in the Intensive Care Unit (ICU). Material and methods: Multidisciplinary, observational, retrospective, single-center study that included all patients with COVID-19 in ICU who were treated with ganciclovir or foscarnet between March-2020 and April-2021 in a tertiary hospital. Variables: demographic, related to treatment for CMV, treatment received for COVID-19, hospital stay, in-hospital mortality and at discharge. Results: In the study period, 26 critically ill patients with COVID-19 received some anti-cytomegalovirus treatment (69.2% men, median age 64 years). In 15 (57.7%) reactivation was confirmed microbiologically, and these patients had longer stays than those treated without confirmation. Mortality in the treated group was 84.6% (80.0% in those with confirmed reactivation), compared to 43% mortality in the overall of 300 COVID-19 patients who required ICU in that period. The demonstrated infection rate of CMV was 5.0%. Conclusions: Although there are publications that suggest a higher risk of CMV reactivation in COVID-19 patients, the incidence in our study was lower than that described in critical COVID patients. It should be noted the high mortality in the study patients compared to the overall number of patients seen in the ICU for COVID-19. (AU)
