Central-line-associated bloodstream infections and central-line-associated non-CLABSI complications among pediatric oncology patients.

OBJECTIVE: To assess central venous catheter (CVC) harm in pediatric oncology patients, we explored risks for central-line-associated bloodstream infections (CLABSIs) and central-line-associated non-CLABSI complications (CLANCs). DESIGN: Retrospective cohort study. SETTING: Midwestern US pediatric oncology program. PATIENTS: The study cohort comprised 592 pediatric oncology patients seen between 2006 and 2016. METHODS: CLABSIs were defined according to Centers for Disease Control and Prevention (CDC)/National Health Safety Network (NHSN) definitions. CLANCs were classified using a novel definition requiring CVC removal. Patient-level and central-line-level risks were calculated using a negative binomial model to adjust for correlations between total events and line numbers. RESULTS: CVCs were inserted in 62% of patients, with 175,937 total catheter days. The inpatient CLABSI and CLANC rates were 5.8 and 8.5 times higher than outpatient rates. At the patient level, shared risks included acute myeloid leukemia (AML) and age <1 year at diagnosis. At the line level, shared risks included age <1 year at diagnosis, non-mediports, and >1 lumen. AML was a CLABSI-specific risk. CLANC-specific risks included non-brain-tumor diagnosis, younger age at diagnosis or central-line placement, and age <1 year at diagnosis or line placement. Multivariable risks were for CLABSI >1 lumen and for CLANC age <1 year at placement. CONCLUSIONS: Among patients with CVCs, CLABSI and CLANC rates were similar, higher among inpatients than outpatients. For both CLABSIs and CLANCs, infants and patients with AML were at higher risk. In both univariate and multivariate models, lines with >1 lumen were associated with CLABSIs and placement during infancy with CLANCs.

Extranodal marginal zone B cell lymphoma: An unexpected complication in children with Sjögren's syndrome / Linfoma no Hodgkin de linfocitos B de la zona marginal, extranodal: una complicación inesperada en niños con síndrome de Sjögren

Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by the infiltration of lymphocytes into exocrine glands, resulting in the typical sicca symptoms. Unlike adults, primary SS is a very rare condition in childhood, and the risk of malignancy in juvenile SS (JSS) has not been defined. We report the detection of extranodal marginal zone B-cell lymphoma (EMZL) occurring in two children with SS. Fine needle aspiration of the salivary glands (SG) showed nonspecific findings that led to delayed diagnosis of SS. The diagnosis of B-cell lymphoma associated with JSS was based on morphologic and immunohistochemical staining done during the biopsy. To highlight awareness of EMZL as a timely and appropriate update of an unusual complication in children with SS

El síndrome de Sjögren (SS) es una enfermedad sistémica autoinmune caracterizada por la infiltración de linfocitos en glándulas exocrinas, provocando el típico síndrome seco. A diferencia de los adultos, el SS es una afección rara en niños, y el riesgo de malignización no ha sido descrito. Describimos la detección de linfoma B de la zona marginal extranodal de tejido linfoide asociado a mucosa (linfoma MALT) en 2 niños con SS. La aspiración con aguja fina de las glándulas salivares (SG) mostró hallazgos inespecíficos que retrasaron el diagnóstico de SS. El diagnóstico de linfoma B asociado a SS juvenil se realizó con base en los hallazgos morfológicos e inmunohistoquímicos detectados en biopsia. Hay que tomar conciencia de que un linfoma B puede acontecer en el curso de un SS como una complicación inesperada en niños, principalmente para realizar una derivación correcta a oncología
