Antimicrobial Sensitivity Test

Infection in pediatric cancer patients has become a concerning problem due to increasing antimicrobial resistance. The goal of this study was to determine the antimicrobial resistance patterns of blood isolates from pediatric oncology patients in Iran to determine if quinolones are appropriate for empiric therapy. Methods Children with cancer who were admitted with or developed fever during admission to Aliasghar Children’s Hospital or Mahak Hospitals July 2009 through June 2011 were eligible for enrollment. Two blood cultures were obtained.  Antimicrobial sensitivity test was performed for ciprofloxacin, moxifloxacin, gatifloxacin, meropenem, cefepime, and piperacillin-tazobactam on isolates from children who were bacteremic. Results Blood cultures were positive for 39 episodes in 169 enrolled children but 9 episodes were excluded as blood cultures were thought to be contaminated,  yielding a bacteremia rate of 29/160 (18%). The mean age of children and the stage of malignancy did not differ between those with and without bacteremia. Meropenem was the most likely antibiotic to cover isolates (97%) with cefepime having the lowest coverage rate (21%). Quinolone coverage ranged from 63%  to 76%. Conclusion Quinolones are not suitable for use as empiric therapy in febrile pediatric oncology patients in Iran.

Objective: The study aimed to describe the identity and antimicrobial resistance patterns of the causative agents of bacterial meningitis in children referred to Children’s Medical Center (CMC) Hospital, Tehran, Iran. Methods: This retrospective study was performed at CMC Hospital during a six-year period from 2011 to 2016. The microbiological information of the patients with a diagnosis of bacterial meningitis was collected and the following data were obtained: patients’ age, sex, hospital ward, the results of CSF and blood cultures, and antibiotic susceptibility profiles of isolated organisms. Results: A total of 118 patients with bacterial meningitis were admitted to CMC hospital. Sixty-two percent (n=73) of the patients were male. The median age of the patients was ten months (interquartile range [IQR]: 2 months-2 years) and the majority of them (n=92, 80%) were younger than two years of age. The highest number of patients (n=47, 40%) were admitted to the surgery department. Streptococcus epidermidis was the most frequent isolated bacterium (n=27/127, 21%), followed by Klebsiella pneumoniae (n=20/127, 16%), and Staphylococcus aureus (n=16/127, 12.5%). Blood culture was positive in 28% (n=33/118) of patients. Ampicillin-sulbactam and imipenem were the most effective antibiotics against Gram-negative bacteria isolated from CSF cultures. In the case of Gram-positive organisms, ampicillinsulbactam, vancomycin, and linezolid were the best choices. Imipenem was the most active drug against Gram-negative blood pathogens. Also, ampicillin and vancomycin had the best effect on Gram-positive bacteria isolated from blood cultures. Conclusion: Results of this study provide valuable information about the antibiotic resistance profiles of the etiologic agents of childhood meningitis, which can be used for prescription of more effective empirical therapies.

The Impact

Abstract Background Infectious processes are frequent complications presented in pediatric patients with cancer. Currently, the indiscriminate use of antibiotics induces resistance to available treatments, creating the emergence of multi-drug-resistant organisms (MDROs). Due to the impact in morbidity and mortality secondary to MDRO infection, we aimed to identify risk factors associated with mortality in infections due to MDROs in pediatric patients with cancer. Methods Case–control study nested in a prospective cohort of pediatric oncology patients with febrile neutropenia (FN) at Hospital Infantil de México Federico Gómez (HIMFG) in Mexico City from March 2015 to September 2017. MDRO was defined as acquired non-susceptibility to at least one agent in three or more antimicrobial categories. Patients with FN episodes who died from an infection due to MDROs were defined as cases and patients with FN episodes of an infection due to MDROs who did not die were defined as controls. Mucositis, septic shock, PICU stay, and bacterial prophylaxis (Trimethoprim/Sulfamethoxazole) were compared between groups. Descriptive statistics was performed and Pearson χ 2 or Student’s t-test were used to compare risk factors between groups. Results A total of 929 FN episodes were documented, 44.4% episodes occurred in male patients, mean age was 7.9 years, with the population under 5 years being the most represented (68.2%). The most frequent diagnosis was acute lymphoblastic leukemia in 75% followed by rhabdomyosarcoma in 10.5% and acute myeloid leukemia in 9.6%. Prophylaxis (trimethoprim/sulfamethoxazole) was used in 86%, mucositis was present in 9.2% of episodes. 12.1% had septic shock and 4.7% were admitted to PICU. In 148 FN episodes (15.9%) a microorganism was identified, of these 50 (33.7%) were due to an MDROs. Urinary tract infection was the most frequent site (49%), followed by bloodstream infections (47%). K. pneumoniae was the most frequent MDRO in 22.8%, followed by E. coli in 19.2% and P. aeruginosa in 14%. Septic shock was presented in 26% of MDROs infections. Overall mortality was 1.94% and only 0.86% (8) were secondary to MDROs. Of patients with MDRO isolated mortality was 30% (15/50). Mortality associated with bloodstream infection due to MDROs was 25% compared with other source of MDROs infections (3%) (P = 0.01). Septic shock was present in 40% of patients with death due to MDROs infection (P = 0.001). Conclusions In our population of children with FN episodes who had an isolated microorganism, infection due to MDROs are high (33.7%) and MDROs infection-directed mortality was as high as 30%. Bloodstream infections and septic shock were risk factors associated with mortality due to MDROs.

Abstract Background Choice of empiric therapy for pneumonia depends on risk for antimicrobial resistance. Models to predict resistance are derived from blood and respiratory culture results. We compared these results to understand if organisms and resistance patterns differed by site. We also compared characteristics and outcomes of patients with positive cultures by site. Methods We studied adult patients discharged from 177 US hospitals from July 2010 through June 2015, with principal diagnoses of pneumonia, or principal diagnoses of respiratory failure, acute respiratory distress syndrome, respiratory arrest, or sepsis with a secondary diagnosis of pneumonia, and who had blood or respiratory cultures performed. Demographics, treatment, microbiologic results, and outcomes were examined. Results Among 138 561 hospitalizations of patients with pneumonia who had blood or respiratory cultures obtained at admission, 12 888 (9.3%) yielded positive cultures: 6438 respiratory cultures, 5992 blood cultures, and 458 both respiratory and blood cultures. Forty-two percent had isolates resistant to first-line therapy for community-acquired pneumonia. Isolates from respiratory samples were more often resistant than were isolates from blood (54.2% vs 26.6%; P < .001). Patients with both culture sites positive had higher case-fatality, longer lengths of stay, and higher costs than patients who had only blood or respiratory cultures positive. Among respiratory cultures, the most common pathogens were Staphylococcus aureus (34%) and Pseudomonas aeruginosa (17%), whereas blood cultures most commonly grew Streptococcus pneumoniae (33%), followed by S. aureus (22%). Conclusions Patients with positive respiratory tract cultures are clinically different from those with positive blood cultures, and resistance patterns differ by source. Models of antibiotic resistance should account for culture source.

26 Background: Traditionally, pediatric oncology patients with fever and severe neutropenia (absolute neutrophil count [ANC] <500) are admitted on empiric intravenous (IV) antibiotics pending blood cultures, fever resolution, and a rising ANC. Based on significant evidence that risk-stratification of these patients with fever and neutropenia (FN) and outpatient management of “low-risk” FN (LRFN) patients with oral antibiotics can be safe and effective, we implemented an institutional clinical practice guideline (CPG) to provide outpatient care for children with LRFN. Methods: A validated “Alexander” clinical decision rule was adopted to risk stratify pediatric oncology patients with FN. A new CPG was formulated for the outpatient management of LRFN patients, with either discharge on presentation or at 24-48 hours after admission, with levofloxacin and close follow-up. All stakeholders were educated regarding the new guidelines and process prior to implementation, and the guidelines were approved by the institutional Evidence Based Outcomes Center. Results: In 9 months since guideline implementation, 10/11 (91%) of the eligible patients have been managed outpatient for LRFN (mean ANC 160, range 0 - 480). Seven patients were discharged home from the ER or oncology clinic. Three patients were discharged early at 24 – 48 hours after admission. Outpatient management was safe, and all but one patient had resolution of fever within 48 hours and negative blood cultures. One patient had a positive blood culture with Staphylococcus epidermidis and was admitted for IV antibiotics with no complications. Parents of 9/10 patients responded to surveys. All 9 families found outpatient management to be a good experience, follow-up easy, and reported no adverse effects with levofloxacin. One family preferred inpatient care due to anxiety, while importantly 8/9 (89%) parents said they preferred outpatient care compared to inpatient observation. Conclusions: Pediatric oncology patients with low-risk fever and neutropenia were successfully idenitified and managed in the outpatient setting without adverse events with a high level of parent satisfaction.

Abstract Background Clostridioides difficile infection (CDI) is a significant source of morbidity in pediatric cancer patients. Few reports to date have evaluated risk factors and short-term outcomes for this population. Methods We retrospectively evaluated pediatric oncology admissions at St Louis Children’s Hospital from 2009 to 2018. All inpatient cases of diagnosed initial CDI were identified. We aimed to investigate the prevalence of CDI and associated risk factors, including coadmission with another patient with CDI, and to evaluate short-term outcomes including length of stay and delays in subsequent scheduled chemotherapy. Results Review of 6567 admissions from 952 patients revealed 109 CDI cases (11.4% of patients). Patients with leukemia or lymphoma, compared to those with solid tumors, were more likely to have CDI (odds ratio [OR], 3 [95% CI, 1.4–6.6], and 3 [95% CI, 1.3–6.8], respectively). Autologous hematopoietic stem cell transplant (HSCT) was also a risk factor (OR, 3.5 [95% CI, 1.7–7.4]). Prior antibiotic exposure independently increased the risk for CDI (OR, 3.0 [95% CI, 1.8–4.8]). Concurrent admission with another patient with CDI also significantly increased the risk (OR, 84.7 [95% CI, 10.5–681.8]). In contrast to previous reports, exposure to acid-suppressing medications decreased the risk for CDI (OR, 0.5 [95% CI, .3–.7]). CDI was associated with increased length of stay (mean difference, 8 days [95% CI, 4.6–11.4]) and prolonged delays for subsequent chemotherapy (mean difference, 1.4 days [95% CI, .1–2.7]). Conclusions CDI in pediatric oncology patients significantly prolongs hospitalization and delays chemotherapy treatment plans. Interventions to control CDI will improve the care of pediatric oncology patients.
