Abstract
Large granular lymphocytic (LGL) leukemia is a rare form of incurable chronic leukemia frequently complicated by life-threatening cytopenias. The less common NK-cell variant of this disorder poses a diagnostic challenge and its etiologic basis is poorly understood. Here we present the case of an elderly man diagnosed with LGL leukemia after presenting with severe Coombs-negative hemolytic anemia, who had a robust durable response to oral cyclophosphamide. Close to two years after initial diagnosis, he developed a florid Mycobacterium avium-intracellulare (MAI) infection of the lungs. We discuss the clinical and pathologic features of this case, highlighting aspects common to this disorder and areas of clinical uncertainty. We hope to both raise awareness of the risk for pulmonary MAI infection in patients treated with lymphodepleting drugs and to motivate the prospective evaluation of strategies to prevent opportunistic infections in LGL leukemia.

Abstract
Prophylaxis of Pneumocystis jiroveci pneumonia (PJP) with trimethoprim/sulfamethoxazole is a standard of care for children with hematologic malignancies, while its use in solid tumor patients is still debated. A retrospective study focusing on the use of PJP prophylaxis in patients with solid tumors was performed among 16 AIEOP centers: 1046/2863 patients did not receive prophylaxis and no cases of PJP were reported.

Abstract
Current recommendations for prophylaxis of Pneumocystis jirovecii pneumonia in oncology patients include administration of trimethoprim/sulfamethoxazole (TMP/SMX) three times weekly or the same total weekly dose given daily. The primary objective of this study was to evaluate the efficacy of two consecutive days per week of TMP/SMX for prevention of Pneumocystis jirovecii pneumonia (PJP) in pediatric oncology patients. A retrospective cohort, single-center analysis was conducted in oncology patients 21 years and younger who received TMP/SMX for PJP prophylaxis between February 1, 2013 and July 31, 2017. Changes to the prophylaxis regimen were documented and analyzed. A total of 322 patients received TMP/SMX on two consecutive days per week for PJP prevention, of whom four had confirmed PJP (1.3%). Neutropenia was the most common reason for switching to alternative prophylaxis therapy (11.5%). Two consecutive prophylaxis days with TMP/SMX may be insufficient to prevent PJP in children with hematologic malignancies. Neutropenia remains a barrier for TMP/SMX use for PJP prophylaxis. Further studies to compare PJP incidence in children receiving alternative prophylaxis regimens should be considered.

Abstract
Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection that mostly affects children with suppressed cellular immunity. PJP was the most common cause of infectious death in children with acute lymphoblastic leukemia prior to the inclusion of cotrimoxazole prophylaxis as part of the standard medical care in the late 1980s. Children with acute leukemia, lymphomas, and those undergoing hematopoietic stem cell transplantation, especially allogeneic transplantation, are also at high risk of PJP. Persistent lymphopenia, graft versus host disease, poor immune reconstitution, and lengthy use of corticosteroids are significant risk factors for PJP. Active infection may be due to reactivation of latent infection or recent acquisition from environmental exposure. Intense hypoxemia and impaired diffusing capacity of the lungs are hallmarks of PJP, while computerized tomography of the lungs is the diagnostic technique of choice. Immunofluorescence testing with monoclonal antibodies followed by fluorescent microscopy and polymerase chain reaction testing of respiratory specimens have emerged as the best diagnostic methods. Measurement of (1-3)-β-D-glucan in the serum has a high negative predictive value in ruling out PJP. Oral cotrimoxazole is effective for prophylaxis, but in intolerant patients, intravenous and aerosolized pentamidine, dapsone, and atovaquone are effective alternatives. Ιntravenous cotrimoxazole is the treatment of choice, but PJP has a high mortality even with appropriate therapy.

Abstract
The improvement in overall survival in children with acute lymphoblastic leukemia (ALL) over the last 5 decades has been considerable, with around 90% now surviving long term. The risk of relapse has been reduced to such an extent that the risk of treatment-related mortality is now approaching that of mortality caused by relapse. Toxicities may also lead to the suboptimal delivery of chemotherapy (treatment delays, dose reductions, dose omissions), potentially increasing relapse risk, and short- and long-term morbidity, adding to the "burden of therapy" in an increasing number of survivors. Thus, the need to reduce toxicity in pediatric ALL is becoming increasingly important. This work focuses on the risk factors, pathogenesis, clinical features, and emergency management of the life-threatening complications of ALL at presentation and during subsequent chemotherapy, including leucostasis, tumor lysis syndrome, infection, methotrexate encephalopathy, thrombosis, and pancreatitis. Potential strategies to abrogate these toxicities in the future are also discussed.

Abstract
STUDY OBJECTIVE To study dapsone in comparison with trimethoprim/sulfamethoxazole (TMP/SMX) for Pneumocystis jiroveci (PJP) prophylaxis in children with acute lymphoblastic leukemia (ALL). DESIGN A retrospective study with a prospective follow-up. PATIENTS Pediatric ALL patients diagnosed between May 2009 and May 2014, who are still receiving or have completed their maintenance chemotherapy. Patients who completed chemotherapy were prospectively followed up for neutropenia. METHODS TMP/SMX was used as the initial PJP prophylaxis. An alternative drug was indicated if the patient remained cytopenic for >3 weeks. Average absolute neutrophilic count (ANC), average % of oral mercaptopurine (6-MP), and methotrexate doses were calculated over a period of 6 months before and after shifting to dapsone. RESULTS Sixty-two ALL patients were eligible for analysis. Twenty-four patients (38.7%) received TMP/SMX for PJP prophylaxis, whereas 34 patients received Dapsone (54.8%). Only 3 patients received IV pentamidine (4.8%), whereas 1 patient (1.6%) received atovaquone. The incidence of prophylaxis failure was 1/1041 months on TMP/SMX and 1/528 months on dapsone. After shifting to dapsone, patients maintained significantly higher ANC (1.46±0.46 vs. 1.17±0.40, P=0.0053), and received significantly higher doses of 6-MP (62.61%±11.45 vs. 57.45±10.14, P=0.0081) and methotrexate (64.9%±14.29 vs. 56.5%±9.9, P=0.0176), with a significantly shorter duration of chemotherapy interruption (1.94±1.2 vs. 3.25±1.29 wk, P=0.0002). CONCLUSIONS Dapsone for PJP prophylaxis in ALL allowed patients to maintain higher ANC and to receive higher doses of chemotherapy, while maintaining a low incidence of PJP breakthrough infection.

Abstract
Pediatric patients receiving conventional chemotherapy for malignant disease face an increased risk of bloodstream infection (BSI). Since BSI may represent an acute life-threatening event in patients with profound immunosuppression, and show further negative impact on quality of life and anticancer treatment, the prevention of BSI is of paramount importance to improve and guarantee patients' safety during intensive treatment. The great majority of all pediatric cancer patients (about 85%) have a long-term central venous access catheter in use (type Broviac or Port; CVAD). Referring to the current surveillance definitions a significant proportion of all BSI in pediatric patients with febrile neutropenia is categorized as CVAD-associated BSI. This state of the art review summarizes the epidemiology and the distinct pathogen profile of BSI in pediatric cancer patients from the perspective of infection surveillance. Problems in executing the current surveillance definition in this patient population are discussed and a new concept for the surveillance of BSI in pediatric cancer patients is outlined.

Abstract
The 5th European Conference on Infections in Leukaemia (ECIL-5) meeting aimed to establish evidence-based recommendations for the prophylaxis of Pneumocystis jirovecii pneumonia (PCP) in non-HIV-infected patients with an underlying haematological condition, including allogeneic HSCT recipients. Recommendations were based on the grading system of the IDSA. Trimethoprim/sulfamethoxazole given 2-3 times weekly is the drug of choice for the primary prophylaxis of PCP in adults ( A-II: ) and children ( A-I: ) and should be given during the entire period at risk. Recent data indicate that children may benefit equally from a once-weekly regimen ( B-II: ). All other drugs, including pentamidine, atovaquone and dapsone, are considered second-line alternatives when trimethoprim/sulfamethoxazole is poorly tolerated or contraindicated. The main indications of PCP prophylaxis are ALL, allogeneic HSCT, treatment with alemtuzumab, fludarabine/cyclophosphamide/rituximab combinations, >4 weeks of treatment with corticosteroids and well-defined primary immune deficiencies in children. Additional indications are proposed depending on the treatment regimen.

Abstract
Infections in children and adolescents with cancer are a significant cause of morbidity and mortality, especially in those receiving chemotherapy who are neutropenic and/or immunocompromised. The aim of this article is to review existing evidence in order to provide a practice recommendation to prevent or minimize infections in neutropenic and/or immunocompromised patients receiving chemotherapy and/or stem cell transplant. Systematic reviews were undertaken and research was graded according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. A variety of interventions are implemented to reduce infections in the neutropenic and/or immunocompromised population; however, few are supported by research evidence. Existing literature should continue to be reviewed to further identify interventions that can influence positive patient outcomes and provide opportunities for individuals in the medical field to work together to improve clinical care.

Abstract
OBJECTIVE To determine whether a simplified, 1-day/week regimen of trimethoprim/sulfamethoxazole is sufficient to prevent Pneumocystis (jirovecii [carinii]) pneumonia (PCP). Current recommended regimens for prophylaxis against PCP range from daily administration to 3 consecutive days per week dosing. STUDY DESIGN A prospective survey of the regimens adopted for the PCP prophylaxis in all patients treated for childhood cancer at pediatric hematology-oncology centers of the Associazione Italiana Ematologia Oncologia Pediatrica. RESULTS The 20 centers participating in the study reported a total of 2466 patients, including 1093 with solid tumor and 1373 with leukemia/lymphoma (or primary immunodeficiency; n = 2). Of these patients, 1371 (55.6%) received the 3-day/week prophylaxis regimen, 406 (16.5%) received the 2-day/week regimen, and 689 (27.9%), including 439 with leukemia/lymphoma, received the 1-day/week regimen. Overall, only 2 cases of PCP (0.08%) were reported, both in the 2-day/week group. By intention to treat, the cumulative incidence of PCP at 3 years was 0.09% overall (95% CI, 0.00-0.40%) and 0.51% for the 2-day/week group (95% CI, 0.10%-2.00%). Remarkably, both patients who failed had withdrawn from prophylaxis. CONCLUSION A single-day course of prophylaxis with trimethoprim/sulfamethoxazole may be sufficient to prevent PCP in children with cancer undergoing intensive chemotherapy regimens. This simplified strategy might have implications for the emerging need for PCP prophylaxis in other patients subjected to the increased use of biological and nonbiological agents that induce higher levels of immune suppression, such as those with rheumatic diseases.

Abstract
Pneumocystis pneumonia (PCP) remains a leading opportunistic infection in patients with weakened immune systems. The fungus causing the infection belongs to the genus, Pneumocystis, and its members are found in a large variety of mammals. Adaptation to the lung environment of a host with an intact immune system has been a key to its successful survival. Unfortunately, the metabolic strategies used by these fungi to grow and survive in this context are largely unknown. There were considerable impediments to standard approaches for investigation of this unique pathogen, the most problematic being the lack of a long term in vitro culture system. The absence of an ex vivo cultivation method remains today, and many fundamental scientific questions about the basic biology, metabolism, and life cycle of Pneumocystis are unanswered. Recent progress in sequencing of the Pneumocystis carinii genome, a species infecting rats, permitted a more informative search for genes and biological pathways within this pathogen that are known to be targets for existing antifungal agents. In this work, we review the classes of antifungal drugs with respect to their potential applicability to the treatment of PCP. Classes covered in the review are the azoles, polyenes, allylamines, and echinocandins. Factors limiting the use of standard antifungal treatments and the currently available alternatives (trimethoprim-sulfamethoxazole, atovaquone, and pentamidine) are discussed. A summary of genomic sequences within Pneumocystis carinii associated with the corresponding targeted biological pathways is provided. All sequences are available via the Pneumocystis Genome Project at http://pgp.cchmc.org/.
