Safety of empirical antibiotic therapy discontinuing for fever of unknown origin during high-risk neutropenia in children. J Infect 2024; 88:106171. [PMID: 38697268 DOI: 10.1016/j.jinf.2024.106171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 04/19/2024] [Accepted: 04/24/2024] [Indexed: 05/04/2024]
Abstract
BACKGROUND ECIL-2021 recommends discontinuing empirical antibiotic therapy (EAT) in febrile-neutropenic children after 72 h of treatment and at least 24-48 h of apyrexia in the case of fever of unknown origin (FUO). These guidelines are rarely applied to high-risk children's neutropenia. MATERIAL AND METHODS We retrospectively included all consecutive FUO episodes occurring during profound neutropenia ≥ 10 days in children in our institution. We evaluated the safety of EAT discontinuation in patients for whom the ECIL guidelines were followed compared to those for whom they didn't. We used a combined criterion of mortality and intensive care unit admission at 30 days. We identified risk factors for recurrent fever after EAT discontinuation. RESULTS Fifty-one FUO episodes occurred in 37 patients. EAT discontinuation followed ECIL guidelines in 19 (37 %) episodes. No deaths and-or transfers in ICU occurred in the ECIL group. The duration of EAT was shorter by nine days in the group following ECIL guidelines (p < 0.001). We observed 14 (27 %) episodes of recurrent fever. Mucositis was significantly associated with recurrent fever (p < 0.01). CONCLUSION EAT discontinuation seems feasible and safe in FUO during prolonged febrile neutropenia in children. However, mucosal lesions should prompt thorough surveillance due to the risk of recurrent fever.

Abstract
PURPOSE Congenital malformations are strong risk factors for childhood cancer. Our objective was to determine whether cancer survival differs by birth defect status among Oklahoma children. METHODS We used accelerated failure time models to estimate survival time ratios (SRs) and 95% confidence intervals (CIs), adjusted for maternal race/ethnicity and census tract-level poverty, among children diagnosed with cancer and born in Oklahoma from 1997 to 2012 (n = 971), by linking records from birth certificates, birth defects, and cancer registries. RESULTS We observed decreased, though imprecise, survival time among survivors with any birth defect (SR: 0.82, 95% CI: 0.29, 2.31) or chromosomal defects (n = 24) (SR: 0.43, 95% CI: 0.06, 3.30) compared to those without birth defects. We observed no difference in survival time among children with non-chromosomal defects (SR: 0.98, 95% CI: 0.31, 3.12) compared to children with no birth defects. CONCLUSION Our study did not identify significant differences in cancer survival for children with and without birth defects. Future studies should consider pooling data from multiple states to allow in-depth study of specific birth defects and cancer types and confirm whether survival differs by type and number of birth defects.

Abstract
PURPOSE Outcome of T-cell lymphoblastic lymphoma (T-LBL) in children is around 75-85% of event-free survival. The role of early intensification to improve outcome while using short infusions of high dose methotrexate (HDMTX) and shorter maintenance treatment was addressed by the French Society of Pediatric Oncology (SFOP) group. METHODS From 1997 through 2003, 79 children (52 males; median age 10.5 years) were prospectively registered into the SFOP LMT 96 trial. The LMT96 protocol, with elements from the protocol of the Berlin-Frankfurt-Münster (BFM) Group included four main modifications: (a) 10 courses of HD-MTX (3 g/m(2) ) delivered over the first 44 weeks; (b) early intensification with cyclophosphamide together with the first course of HD-MTX; (c) a maintenance phase that included 6 monthly intensified chemotherapy pulses; and (d) treatment duration of 18 months for stages I-III. RESULTS Eighty-nine percent of patients had an initial mediastinal involvement. With a median follow-up of 87 months, the 5-year event-free survival was 85% and overall survival 89%. Nine patients relapsed, eight during treatment. The early intensification did not change the pattern of relapses. Only 58% of patients experienced grade 3-4 neutropenia during the induction phase, 13% patients experienced grade 3 and 4 mucositis, and 5% patients experienced diabetes. The early intensification did not delay phases of chemotherapy. CONCLUSIONS Early intensification in treatment for T-LBL in children is manageable. Three-hour infusion of HD-MTX did not jeopardize patient outcome. Our results are comparable with those of other international protocols in spite of shorter maintenance treatment for stages I-III.

Abstract
BACKGROUND Down syndrome is known for its association with neoplasms. The aim of this study was to examine this association. METHODS We surveyed the association with benign and malignant neoplasms in Down syndrome patients registered in the Annual of Pathological Autopsy Cases of Japan (1974-2000), a database of autopsied cases operated by the Japanese Society of Pathology. RESULTS In a total of 1514 cases with Down syndrome, there were eight cases with 10 benign tumors (four male and four female) and 104 cases with malignant disorders (61 male, 42 female and one case with unrecorded sex), in which 87 cases with hematopoietic malignancies (83.7%) and 17 cases with solid tumors (16.3%), were identified. The association of gallbladder adenocarcinoma with a benign tumor of the colon was noted in one case, while a further two cases with double benign tumors were confirmed as well. No case with a double malignancy was found. Hematopoietic malignancies (87 cases) included 31 cases (35.6%) with acute myelocytic leukemia, 10 (11.4%) with acute lymphocytic leukemia and two (2.3%) with chronic myelocytic leukemia. The ratio of acute myelocytic leukemia to acute lymphocytic leukemia was 3.1 in the present study. A peak in the age distribution was at 0 years in our data in contrast to the previous data (at 1 year) for myelocytic leukemia. The 17 solid tumors identified included three hepatocellular carcinomas, three extrahepatic cholangiocarcinomas, two gallbladder adenocarcinomas, three brain tumors, and three seminomas. CONCLUSION We present new associations of benign and malignant tumors with Down syndrome.

Abstract
WHAT IS KNOWN AND OBJECTIVE In industrialized countries, acute lymphoblastic leukaemia (ALL) is the most frequent cancer in children aged less than 15 years. High-dose methotrexate is a common component of many chemotherapeutic protocols for childhood with ALL. Our objective was to retrospectively evaluate the pharmacokinetics and plasma levels of high-dose methotrexate as it relates to event-free survival (EFS) in children with ALL. METHODS Relapsed patients and subjects in EFS were compared for MTX serum concentrations 24, 36, 48 and 72 h after the start of 24 h infusion. Clearance (Cl), area under the curve (AUC) and volume of distribution (V(d) ) of the drug were estimated by the NONMEM computer program and also compared between both groups. RESULTS AND DISCUSSION Among 69 children included, 54 (78·3%) were still in EFS, whereas 15 (21·7%) relapsed. The difference between relapsed and EFS patients for the pharmacokinetic parameters studied was not significant. On the contrary, the cohort studied was representative and known prognostic factors for relapse in ALL were significantly associated with relapse. WHAT IS NEW AND CONCLUSION Serum concentrations and pharmacokinetic parameters of MTX are not associated with outcome in ALL. Prognoses based on single-drug pharmacokinetic estimates within a complex multiple-agent protocol appear to be unreliable. However, therapeutic drug monitoring of high-dose methotrexate remains a useful tool for early detection of impaired elimination and for avoiding systemic toxicity.

Abstract
BACKGROUND We assessed the number and causes of treatment-related deaths (TRDs) in childhood cancer over time and correlated them with adherence to therapeutic guidelines. PROCEDURE We compared two cohorts of children of the Childhood Cancer Registry of the Rhône-Alpes Region: Cohort I (1987-1992, 909 patients) and Cohort II (1996-1999, 648 patients). RESULTS In all cancers together, 75 TRDs were reported in Cohort I and 24 in Cohort II (P = 0.001). Cumulative incidence at 5 years declined from 7.9% to 4.1%, and overall survival (OS) increased from 71.0% to 77.2%. TRDs declined by nearly 10-fold in patients with solid malignant tumors (P = 0.02) and central nervous system tumors (P = 0.001), but OS improved for patients with solid malignant tumors only (P = 0.01). No difference was observed in treatment- and transplantation-related deaths in patients with acute lymphoblastic leukemia (ALL) and acute myeloblastic leukemia (AML), but OS was better in patients with AML (P = 0.02). Between the two cohorts, transplantation-related mortality did not decrease and was higher at 5 years in patients with ALL who received unrelated-matched donor transplants (41.3%) than in those receiving sibling-matched donor transplants (18.7%). OS improved in the respective transplant groups (37.0% and 64.2%). Severe graft-versus-host disease was also observed among patients with ALL (P = 0.036). The decrease in TRDs was correlated with compliance to therapeutic guidelines. CONCLUSION Although mortality declined, improved adherence to therapeutic guidelines and more restricted indications of allograft are needed to preclude further treatment- and transplantation-related deaths, particularly among those with leukemia.

Abstract
The authors report the results of 58 children with ALL in 2CR after related (n = 31) or unrelated (n = 27) AHSCT. Characteristics at diagnosis and initial and after relapse antileukemic treatment were similar in the related donor (RD) and the unrelated donor (UD) groups. Conditioning consisted of TBI/CY +/- VP-16 for patients > or = 3 years old (n = 43) and Bu/CY for the rest. Median recipient age was 8 years (range 1-17) in the RD and 9 years (range 3-14) in the UD group. Median follow-up was 54 months (range 24-80) and 52 months (range 22-85) in the RD and the UD groups repectively. The 5-year EFS probability was 43 +/- 9% for the RD group and 36 +/- 9% in the UD group (p = .25). The transplant-related mortality was 16% in the RD and 37% in the UD group (p = .016). In the RD group 36.7% of patients relapsed versus 18.6% in the UD group (p = .05). GvHD associated with organ failure or infection caused most of the transplant-related deaths in both groups. Survivor quality of life for both groups was good (Lansky score < or = 90).

Abstract
Background The t(12;21)(p13;q22) translocation is found in 20 to 25% of cases of childhood B-lineage acute lymphoblastic leukemia (B-ALL). This rearrangement results in the fusion of ETV6 (TEL) and RUNX1 (AML1) genes and defines a relatively uniform category, although only some patients suffer very late relapse. TEL/AML1-positive patients are thus an interesting subgroup to study, and such studies should elucidate the biological processes underlying TEL/AML1 pathogenesis. We report an analysis of gene expression in 60 children with B-lineage ALL using Agilent whole genome oligo-chips (44K-G4112A) and/or real time RT-PCR. Results We compared the leukemia cell gene expression profiles of 16 TEL/AML1-positive ALL patients to those of 44 TEL/AML1-negative patients, whose blast cells did not contain any additional recurrent translocation. Microarray analyses of 26 samples allowed the identification of genes differentially expressed between the TEL/AML1-positive and negative ALL groups. Gene enrichment analysis defined five enriched GO categories: cell differentiation, cell proliferation, apoptosis, cell motility and response to wounding, associated with 14 genes -RUNX1, TCFL5, TNFRSF7, CBFA2T3, CD9, SCARB1, TP53INP1, ACVR1C, PIK3C3, EGFL7, SEMA6A, CTGF, LSP1, TFPI – highlighting the biology of the TEL/AML1 sub-group. These results were first confirmed by the analysis of an additional microarray data-set (7 patient samples) and second by real-time RT-PCR quantification and clustering using an independent set (27 patient samples). Over-expression of RUNX1 (AML1) was further investigated and in one third of the patients correlated with cytogenetic findings. Conclusion Gene expression analyses of leukemia cells from 60 children with TEL/AML1-positive and -negative B-lineage ALL led to the identification of five biological processes, associated with 14 validated genes characterizing and highlighting the biology of the TEL/AML1-positive ALL sub-group.

Abstract
Non-Hodgkin lymphoma (NHL) is rarely observed during infancy and data on its incidence, characteristics and outcome are scarce. The present study aimed to assess the prevalence, clinical presentation and treatment results of all infants who were diagnosed with NHL between October 1986 and December 2002 among 2084 patients treated according to the NHL-BFM (Berlin-Frankfurt-Münster) multicentre trials 86, 90 and 95. We identified 20 (1%) infants with NHL including five with T-cell lymphoblastic lymphoma (T-cell LBL), seven with precursor B-cell LBL (pB-cell LBL), two with a mature Burkitt neoplasm, five with anaplastic large cell lymphoma (ALCL) and one with peripheral T-cell lymphoma (PTCL). The PTCL patient, 3/7 pB-cell LBL and 1/5 ALCL patients relapsed. One patient each from the T-cell LBL and Burkitt lymphoma groups suffered from a second malignancy and one patient each with ALCL and Burkitt leukaemia died from treatment-related toxicity. The 5-year event-free survival rate was 53 +/- 12% for the 20 cases. This study has provided preliminary evidence that infants with NHL have a dismal prognosis and showed that infant NHL differed to lymphomas in older patients with respect to the distribution of gender, histopathologic subtypes as well as the ratio of T- to pB-cell LBL and the frequency of relapses of pB-cell LBL.

Abstract
MLL gene rearrangement is common in both adult and childhood acute myeloid leukaemia (AML), and its role in oncogenesis has been investigated. While over 50 translocated-partner genes have been identified so far, few studies have detailed the molecular mechanism of partial tandem duplication (PTD) of the MLL gene. The prognostic impact and contribution to leukaemogenesis of MLL-PTD, especially in childhood cases, remain unknown. We have established a novel cell line containing MLL-PTD derived from an 11-year-old patient with AML and designated as KOPM-88. KOPM-88 cells exhibited certain characteristics associated with the myeloid lineage including abundant primary granules in the cytoplasm and the expression of myeloperoxidase. The cell growth of KOPM-88 was cytokine independent but was accelerated by granulocyte colony-stimulating factor and granulocyte-macrophage colony-stimulating factor. MLL-PTD of exon 2 to exon 6 and exon 2 to exon 8 was revealed using Southern blotting, fluorescence in situ hybridisation, and reverse transcription polymerase chain reaction/DNA sequencing. Furthermore, non-obese diabetic/severe combined immunodeficient mice inoculated with KOPM-88 cells exhibited leukaemic infiltrations in the bone marrow and hemiparalysis because of compression myelopathy. This is the first report of an in vivo animal model exhibiting the systemic involvement of childhood AML containing MLL-PTD. KOPM-88 cells and our murine model may be useful for investigating the pathogenesis of childhood AML associated with MLL gene rearrangement.

Abstract
OBJECTIVE Berlin-Frankfurt-Munster 95 (BFM-95) is a common chemotherapeutic protocol against acute lymphoblastic leukemia (ALL). This prospective study investigates whether this protocol has an adverse effect on the medial olivocochlear bundle (MOCB) and/or outer hair cells' (OHCs) function. The distortion product otoacoustic emissions (DPOAEs) and their suppression by means of contralateral application of white noise were used for assessing the function of OHCs and the MOCB, respectively. STUDY DESIGN Prospective study. SETTING Oncology and otorhinolaryngology departments in a pediatric hospital. PATIENTS Thirty-six children treated with ALL-BFM-95. INTERVENTIONS Before chemotherapy, a baseline audiologic evaluation with tympanogram, standard and extended high frequency, pure-tone audiometry, and DPOAEs in the absence and presence of white noise was performed in all children. This population was divided in three groups. In a first group (n = 12), the evaluation was repeated after four sessions of vincristine administration; in the second group (n = 12), after 8 sessions; and in the third group (n = 12), several months after completion of the protocol. MAIN OUTCOME MEASURE DPOAEs suppression by contralateral application of white noise. RESULTS In the first and the third groups, we observed no changes in DPOAE amplitudes. Nevertheless, in the second group, the DPOAEs demonstrated significant decrease at 1416, 1685, 2002, and 2380 Hz. At baseline examination, all groups presented significant suppression at all frequencies. After eight vincristine sessions, instead of suppression, an increase of amplitudes was noted at 5 of 12 frequencies. Efferent-mediated DPOAE suppression reappeared in the third group at all frequencies (significant at 5 of 12 frequencies). CONCLUSION ALL-BFM-95 seems to exert an early and reversible toxic effect on the MOCB, whereas its effects on OHCs are minimal and reversible. These minimal cochleotoxic and neurotoxic properties of ALL-BFM-95 might prove useful for research studies on the role of efferent innervation in hearing.

Abstract
Leukaemias constitute approximately one-third of cancers in children (age 0-14 years) and 10% in adolescents (age 15-19 years). Geographical patterns (1988-1997) and time trends (1978-1997) of incidence and survival from leukaemias in children (n=29,239) and adolescents (n=1929) were derived from the ACCIS database, including data from 62 cancer registries in 19 countries across Europe. The overall incidence rate of leukaemia in children was 44 per million person-years during 1988-1997. Lymphoid leukaemia (LL) accounted for 81%, acute non-lymphocytic leukaemia (ANLL) for 15%, chronic myeloid leukaemia (CML) for 1.5% and unspecified leukaemia for 1.3% of cases. Adjusted for sex and age, incidence of childhood LL was significantly lower in the East and higher in the North than in the British Isles. The overall incidence among adolescents was 22.6 per million person-years. The incidence of LL was rising in children (0.6% per year) and adolescents (1.9% per year). During 1988-1997 5-year survival of children with leukaemias was 73% (95% CI 72-74) and approximately 44% for infants and adolescents. Similar differences in survival between children and adolescents were observed for LL, much less so for ANLL. Survival differed between regions; prognosis was better in the North and West than the East. Remarkable improvements in survival occurred in most of the subgroups of patients defined by diagnostic subgroup, age, sex and geographic categories during the period 1978-1997. For children with ANLL most improvements in survival were observed in the 1990s.
