A Disseminated Mycobacterium Abscessus Infection in a Patient Affected by Pulmonary Graft versus Host Disease: Case Report with a Revision of Literature.

Mycobacterium abscessus complex, hereinafter Mab, is a taxonomic group of rapidly growing, nontuberculous mycobacteria (NTM). Despite major advances in understanding virulence, pathogenicity and mechanism of antibiotic resistance, Mab remains a significant cause of pulmonary and extra-pulmonary disease. Herein, we describe a disseminated, macrolide-resistant, Mab subspecies abscessus infection occurring in a severely immune-compromised 34-year-old allotransplanted female patient affected by pulmonary chronic graft versus host disease (cGVHD).

Characteristics and Outcomes of Bloodstream Infections in a Tertiary-Care Pediatric Hematology-Oncology Unit: A 10-Year Study.

Bloodstream infections (BSIs) after chemotherapy or hematopoietic stem cell transplantation (HSCT) are a leading cause of morbidity and mortality. Data on 154 BSIs that occurred in 111 onco-hematological patients (57 hematological malignancies, 28 solid tumors, and 26 non-malignant hematological diseases) were retrospectively collected and analyzed. Monomicrobial Gram-positive (GP), Gram-negative (GN), and fungal BSIs accounted for 50% (77/154), 38.

Hematopoietic Cell Transplantation Cures Adenosine Deaminase 2 Deficiency: Report on 30 Patients.

Purpose: Deficiency of adenosine deaminase 2 (DADA2) is an inherited inborn error of immunity, characterized by autoinflammation (recurrent fever), vasculopathy (livedo racemosa, polyarteritis nodosa, lacunar ischemic strokes, and intracranial hemorrhages), immunodeficiency, lymphoproliferation, immune cytopenias, and bone marrow failure (BMF). Tumor necrosis factor (TNF-α) blockade is the treatment of choice for the vasculopathy, but often fails to reverse refractory cytopenia. We aimed to study the outcome of hematopoietic cell transplantation (HCT) in patients with DADA2.

Long-term and quality of survival in patients treated for acute lymphoblastic leukemia during the pediatric age.

Long-term survival for acute lymphoblastic leukemia (ALL) in children improved over the last three decades up to 80-90% of affected patients. Consequently, the quality of life of survivors has become increasingly important. This study analyses the clinical features and outcome of 119 children with ALL, focusing on the quality of long-term survival in a subset of 22 patients over 18 years of age.

Clinical Characteristics and Outcome of Severe Acute Respiratory Syndrome Coronavirus 2 Infection in Italian Pediatric Oncology Patients: A Study From the Infectious Diseases Working Group of the Associazione Italiana di Oncologia e Ematologia Pediatrica.

Background: Little is known as yet about the outcome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children being treated for cancer.

Methods: We collected information on the clinical characteristics and outcomes of a cohort of 29 children (16 female and 13 male; median age, 7 years [range, 0-16 years]) diagnosed with SARS-CoV-2 infection while on chemotherapy/immunotherapy (n = 26), or after stem cell transplantation (n = 3) during the peak of the epidemic in Italy. These patients suffered from leukemia (n = 16), lymphoma (n = 3), solid tumors (n = 10), and Langerhans cell histiocytosis (n = 1).

Posaconazole delayed-release tablets in paediatric haematology-oncology patients.

Background: To date, there are few studies that describe pharmacokinetics, safety and efficacy of posaconazole delayed-release tablet (DRT) formulation in the paediatric population.

Objectives: We evaluated retrospectively posaconazole plasma concentrations and safety of posaconazole DRT in paediatric haematology-oncology patients.

Patients And Methods: Posaconazole DRT was assessed in 28 haematological paediatric patients with a median age 15 of years (range 5-18) and a median body weight of 50 kg (range 22-83 kg).

Retrospective study on the incidence and outcome of proven and probable invasive fungal infections in high-risk pediatric onco-hematological patients.

Background: Invasive fungal infection (IFI) is a cause of morbidity, mortality and increased health costs in children undergoing chemotherapy or hematopoietic stem cell transplant (HSCT).

Methods: Multicenter, retrospective study to assess the incidence, outcome of proven and probable IFI (PP-IFI) in children treated for acute leukemia, non-Hodgkin lymphoma or who underwent HSCT from 2006 to 2012.

Results: Over the 7-year period, 127 PP-IFI were diagnosed in 123 patients, median age of 9.
