Abstract
OBJECTIVES Pentamidine is an antifungal that is used alternatively to sulfamethoxazole-trimethoprim for the prophylaxis and treatment of Pneumocystis jirovecii pneumonia (PJP). The primary objective of this study was to assess the tolerability of aerosolized versus intravenous pentamidine for PJP prophylaxis in pediatric, adolescent, and young adult immunosuppressed patients. Secondary objectives included comparing pentamidine formulation reaction to dosing frequency and diagnosis. METHODS This retrospective chart review used electronic medical record (EMR) data from patients at a tertiary care pediatric teaching institution from January 1, 2014, to January 1, 2017. Information used from the EMR included pentamidine dosing, ordering, and laboratory values. Inclusion criteria consisted of patients with a cancer diagnosis, hematopoietic stem cell transplant (HSCT) recipients, and renal transplant recipients who received pentamidine for PJP prophylaxis. RESULTS Ninety-six patients met inclusion criteria, of which 31 received aerosolized pentamidine. Ten of the 96 patients experienced a drug-related reaction to either aerosolized or intravenous pentamidine (p = 0.134). Nine of 10 patients who experienced a reaction received intravenous pentamidine versus 1 patient who received aerosolized pentamidine (p = 0.132). In those patients who reacted to pentamidine there was a higher incidence of reactions after subsequent administration (p = 0.039) and in patients with a blood cancer diagnosis (p = 0.042). CONCLUSIONS Data suggest that patients who receive aerosolized pentamidine may tolerate therapy better compared to intravenous administration. Additional studies involving larger numbers of pediatric, adolescent, and young adult patients are needed for stronger statistically significant clinical differences in tolerability of aerosolized versus intravenous pentamidine.

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
BACKGROUND Pneumocystis carinii pneumonia (PCP) is a potentially life-threatening but preventable infection that may occur after hematopoietic stem cell transplantation (HSCT). Intravenous pentamidine has been used in the prevention of PCP in the post-transplant period, although there are few trials published in the literature evaluating its safety and efficacy. METHODS We retrospectively reviewed the medical records of children who underwent HSCT from January 1, 2005, to October 1, 2011, who received intravenous pentamidine as first-line PCP prophylaxis initiated at admission. Demographic, clinical, microbiologic, management and outcome data were collected. RESULTS One hundred sixty-seven consecutive HSCTs in 137 pediatric patients were given intravenous pentamidine before myeloablation and then every 28 days until the subject was at least a minimum 30 days post-HSCT, had stable neutrophil engraftment (absolute neutrophil count >1000/mm for 3 days without growth factor support) and for allogeneic patients, no evidence of active graft versus host disease and weaning on their immunosuppressive therapy. No cases of PCP were seen in this cohort. Ten (7%) had a grade I side effect of nausea/vomiting requiring slower infusion time and 2 (2%) had a grade IV reaction with anaphylaxis (rash) and hypotension with 1 child requiring transfer to the intensive care unit. CONCLUSIONS Intravenous pentamidine was safe and effective for the prevention of PCP in pediatric HSCT patients. Given the potential neutropenic effects of trimethoprim-sulfamethoxazole, compliance with drug administration and inferior efficacy of other PCP prophylactic medications, intravenous pentamidine should be considered as first-line therapy for the prevention of PCP in children undergoing HSCT.

Abstract
Infants with acute lymphoblastic leukemia have a poor prognosis. The Children's Cancer Group (CCG) 1953 protocol tested the hypothesis that intensification of therapy would improve outcome for these patients. This intensified therapy resulted in better disease control, but resulted in greater toxicity. In this paper, we report the infectious complications associated with this intensified therapy. We retrospectively analyzed the infectious complications reported on the case report forms of all 115 patients enrolled on CCG 1953. Overall 495 infectious complications were identified in 115 patients. Bacterial infections occurred most frequently (74%), followed by viral (13%), fungal (11%), and protozoan (1%). Infection related mortality disproportionately occurred with viral (31%) and fungal (19%) infections. Twenty-three percent (n=26) of patients died of infectious complications, with the majority occurring during induction/intensification. Lower respiratory infections contributed to death in 12 patients and were most commonly viral (n=6) and fungal (n=3). Intensification of therapy resulted in increased infectious complications and deaths compared with previous studies. Future studies will need to focus on: (1) decreasing intensification during the first month of therapy, (2) developing targeted therapies, and (3) improving measures designed to prevent, quickly diagnose, and appropriately treat infections.

Abstract
BACKGROUND Pneumocystis jirovecii, formerly carinii, pneumonia (PCP) poses a life-threatening risk to oncology patients. The use of trimethoprim-sulfamethoxazole (TMP-SMZ) prophylaxis virtually eliminates the risk of infection; however, many patients cannot tolerate TMP-SMZ. We performed a retrospective analysis to determine the PCP breakthrough rate in pediatric oncology patients receiving intravenous pentamidine as second line PCP prophylaxis. PROCEDURE We conducted a retrospective chart review of pediatric oncology patients who received intravenous pentamidine from 2001 to 2006 at our institution. The diagnosis, age and bone marrow transplant (BMT) status were determined. A subset of patients had review of their records to determine the justification for discontinuing TMP-SMZ. Children who developed symptoms of pneumonia with a clinical suspicion of PCP underwent bronchoscopy, allowing for identification of Pneumocystis. RESULTS A total of 232 patients received 1,706 doses of intravenous pentamidine and no toxicities were identified. The main reasons for discontinuing TMP-SMZ were bone marrow suppression and drug allergy. Three children developed PCP, equating to a breakthrough rate of 1.3%. Two of these children had undergone BMT (1.9% breakthrough rate) and both were under the age of two (6.5% breakthrough rate). CONCLUSIONS The use of intravenous pentamidine as PCP prophylaxis results in a breakthrough rate of 1.3%. TMP-SMZ is the first choice for PCP prophylaxis. However, when necessary, the use of intravenous pentamidine has an acceptably low failure rate, even in high-risk BMT patients. Other options should be considered for children less than 2 years of age.

Abstract
Pneumocystis carinii pneumonia (PCP) poses a serious risk to allogeneic bone marrow transplant (BMT) patients, who are often intolerant of trimethoprim-sulfamethoxazole (TMP-SMX), the traditional first-line prophylactic agents. There are limited published data supporting the use of aerosolized pentamidine (AP) prophylaxis in the BMT population. We assessed the effectiveness of AP in BMT recipients by reviewing the experience at our center. We divided our review into four time periods from January 1990 to March 2000, during which approximately 700 BMTs were performed. The first period includes patients receiving AP treatments from January 1990 to July 1997 (baseline), the second from August 1997 to July 1998 (pre-outbreak), the third from August 1998 to October 1999 (outbreak), and the fourth from November 1999 to March 2000 (post-outbreak). At our center, TMP-SMX is the first-line agent for PCP prophylaxis, which is routinely continued for at least one year, or for the duration of enhanced immunosuppression. During the baseline period, 505 BMTs were performed and 192 patients (38%) received AP for part of their time at risk. Six patients (3%) experienced toxicities requiring discontinuation of AP. Three cases of PCP were diagnosed over 1114 patient-months of treatment in the baseline period. During the last 42 months of the baseline period, 2/154 patients receiving AP and 2 of an estimated 293 patients receiving exclusively oral prophylaxis developed breakthrough PCP (p = 0.61). During the outbreak period, 9 of 180 patients receiving AP developed PCP compared to none in the group receiving exclusively oral prophylaxis. Either changes in our AP protocol during the pre-outbreak period or pentamidine resistance may have led to this failure of prophylaxis. There were no further cases during the 5-month post-outbreak period. Our observed overall breakthrough rate was 12 cases out of 439 patients (2.7%). Our study shows that AP is an effective and well-tolerated second-line agent in preventing PCP post BMT and we recommend its continued use in this regard. However, it should be administered using a well-studied protocol, and only when TMP-SMX is not tolerated.

Abstract
SUMMARY We assessed the long-term feasibility, safety, and tolerability of two regimens of aerosolized pentamidine (AP) as primary prophylaxis of Pneumocystis carinii pneumonia (PCP) in a large sample of infants and children with symptomatic HIV infection in 21 pediatric departments. One hundred forty children were assigned to receive 60 mg every 2 weeks (n = 60) or 120 mg every 4 weeks (n = 80) of AP, delivered by the ultrasonic nebulizer Fisoneb under the supervision of trained personnel. Children underwent monthly clinical and laboratory controls for toxicity and/or development of PCP for an 18-month period. Baseline characteristics were similar in the two treatment groups. The median age was 5 years. The feasibility of administering AP was excellent in 84 (60 percent) and good in 38 (27 percent) children. All children aged <2 years showed excellent or good feasibility. Long-term compliance was good with both regimens. No child had severe adverse reactions requiring discontinuation of the treatment. Cough, sneezing, and bronchospasm were the most frequent side effects occurring, respectively, in 12, 3.7, and 0.7 percent of the 60-mg treatments and in 19.1, 6. 1, and 2.8 percent of 120-mg treatments (p < 0.05). Their incidence was not different in children younger or older than 5 years. Two episodes of PCP were observed in the group receiving 120 mg monthly, whereas none of the 60 children in the biweekly schedule had PCP (p = 0.20). AP can be safely administered to very young children with few adverse side effects.
