ABSTRACT

Objective: To analyze the clinical characteristics and prognosis of adenovirus infection after allogeneic hematopoietic stem cell transplantation. Methods: A total of 26 patients with adenovirus infection admitted to the posttransplant ward of the First Affiliated Hospital of Soochow University from 2018 to 2022 were enrolled. Their data on baseline and clinical characteristics, treatment, and follow-up were analyzed. Results: The median patient age was 30 (22, 44) years. Twenty-two patients received related haploid stem cell transplantation, three received unrelated stem cell transplantation, and one received umbilical cord stem cell transplantation. Antithymocyte globulin was included in the conditioning regimen in 25 patients. The median time of adenovirus infection was +95 (+44, +152) days. The median peripheral blood lymphocyte count was 0.30 (0.11, 0.69) × 10(9)/L. Twelve patients had acute graft-versus-host disease. Twenty-four patients received antirejection therapies at diagnosis. Sixteen cases had combined infection with other pathogens with adenovirus infection. Eight cases were diagnosed as asymptomatic infection, and 18 were diagnosed as adenovirus disease, including pneumonia (38.89% ) , gastrointestinal disease (38.89% ) , encephalitis (33.33% ) , hepatitis (5.56% ) , and urinary tract inflammation (5.56% ) . The age of >30 years was a risk factor for adenovirus disease (P=0.03) . Eighteen patients received tapering of immunosuppression, and all 26 patients received at least one antiviral drug. Other treatments included high-dose gamma globulin and donor lymphocyte infusion. Adenovirus infection improved in 10 cases and progressed in 16 cases. The median follow-up time was 30 (7, 237) days. Twenty-two patients died. The all-cause mortality rate was (88.5±7.1) % , and the attributable mortality rate was 45.5% . There was no significant difference in the 100 d survival rate between asymptomatic infected patients and patients diagnosed with adenovirus disease (37.5% vs 22.2% , HR=1.83, 95% CI 0.66-5.04, P=0.24) . Conclusion: The age of >30 years was a risk factor for adenovirus disease. Mortality was high in patients with adenovirus infection after allogeneic hematopoietic stem cell transplantation.

ABSTRACT

OBJETIVO. Comparar la gravedad de las infecciones respiratorias agudas bajas (IRAb) producidas por Adenovirus (ADV) entre los años 2015 y 2016, en el Hospital de Niños Roberto del Río. MÉTODOS. Se identificó a pacientes hospitalizados por IRAb por ADV, y se registró edad, sexo, días de hospitalización, ingreso a unidad de paciente crítico (UPC), necesidad de ventilación mecánica (VM), entre otros. Se comparó la evolución de los pacientes, y se analizó la relación entre gravedad y presencia de infecciones asociadas a atención de salud (IAAS). RESULTADOS. Se identificó 158 pacientes hospitalizados por IRAb por ADV. La relación hombre: mujer fue 6:4, con una edad promedio de 17.4 meses. La media de días de hospitalización fue de 9.88 el 2015 y 16.06 el 2016 (p=0.01). El promedio de días de oxigenoterapia fue de 5.86 el 2015 y 8.76 el 2016. Un 22.8% (n:36) de los pacientes ingresó a UPC, y el 20.25% (n:32) requirió VM. Un 41.8% de los casos (n:66) correspondió a IAAS. 3 pacientes fallecieron. CONCLUSIONES. Durante el 2016 hubo hospitalizaciones más prolongadas en comparación al 2015, sin diferencias estadísticamente significativas en relación a requerimientos de oxigenoterapia, VM y fallecimiento. La prolongación de la hospitalización se podría asociar a mayor presencia de IAAS.


OBJETIVE. To compare the severity of lower respiratory infections produced by Adenovirus between 2015 and 2016 at the Hospital de Niños Roberto del Río. METHODS. We identified patients hospitalized for lower respiratory tract infection for ADV and we recorded age, sex, days of hospitalization, admission to Intensive Care Unit (ICU), need for mechanical ventilation (MV), among others. The evolution of the patients between the two years were compared. The relationship between severity and the presence of nosocomial infections was also analyzed. RESULTS. We identified 158 hospitalized patients for ADV. The male:female ratio was 6:4, with an average age of 17.4 months. The mean of hospitalization days was 9.88 days in 2015 and 16.06 days in 2016 (p = 0.01). The average number of oxygen therapy days was 5.86 in 2015 and 8.76 in 2016. The 22.8% (n: 36) of cases required admission in the ICU, and 20.25% (n: 32) required MV. The 41.8% (n: 66) of cases corresponded to nosocomial infections. 3 patients died. CONCLUSIONS. During 2016, there were longer hospitalizations for adenovirus infections compared to 2015, without significant differences in relation to oxygen therapy, MV requirements and death. The prolongation of the hospitalization could be associated by the greater presence of nosocomial infections.

ABSTRACT

Las infecciones por ADV ocurren primariamente en niños menores de cinco años y dan cuenta del 2 a 5 por ciento de las infecciones respiratorias pediátricas y 4 a 10 por ciento de las neumonías. La severidad de las infecciones respiratorias bajas por ADV varía de acuerdo al serotipo involucrado y a factores del huésped como edad, respuesta inmune, factores socioeconómicos y ambientales. La fase aguda de la neumonía por ADV es con condensaciones pulmonares extensas, semejante a una neumonía bacteriana, acompañada de compromiso sistémico y de múltiples órganos muy severa, asociándose a morbilidad y mortalidad importantes. La fase crónica se caracteriza por sibilancias, crepitaciones y dificultad respiratoria, y a veces con dependencia de ventilación mecánica o de oxigeno de curso prolongado. Histológicamente esto corresponde a una Bronquiolitis Obliterante. Entre el 14 y el 50 por ciento de los pacientes pueden desarrollarla. Radiológicamente hay hiperinsuflación, hernias mediastínicas, atelectasias cambiantes y en TC mosaico y bronquiectasias. La evolución de los primeros años es tormentosa. Hacia la edad escolar se estabilizan con compromisos variables de la función pulmonar y persistencia del compromiso obstructivo hasta la adolescencia, edad en la que pueden aparecer nuevas complicaciones y evolucionan como las EPOC de los adultos. Otro grupo de pacientes desarrolla síntomas de asma. Los ADV gatillas crisis de asma y su ADN se ha encontrado en lavados broncoalveolares de asma persistente, todo lo cual lo ubica como un patógeno relevante.
