Abstract
Acute leukemias are complex diseases to treat and have a high mortality rate. The immunosuppression caused by chemotherapy also causes the patient to become susceptible to a variety of infections, including invasive fungal infections. Protocols established in many countries attempt to prevent these infections through the use of pharmacological antifungal prophylaxis. This systematic review and meta-analysis investigates the existing evidence for the use of antifungal prophylaxis in patients undergoing induction chemotherapy for acute leukemia, and how prophylaxis can affect treatment response and mortality. Through the use of a population-variable-outcome strategy, keywords were utilized to search online databases. The included studies were selected and the data was collected to develop descriptive results for all studies, and, for studies that met the criteria, a meta-analysis of the Relative Risk (RR) was analyzed for infection rates, in-hospital mortality, and complete remission. A total of 33 studies were included in this systematic review, with most studies presenting positive results (n = 28/33) from the use of antifungal prophylaxis. Using a random effects model, the pooled results of the meta-analysis presented lower invasive fungal infections in AML (RR: 0.527 (95% CI: 0.391; 0.709). p < 0.001). p < 0.001) and ALL (RR: 0.753 (95% CI: 0.574; 0.988). p = 0.041). when antifungal prophylaxis was used. No discernible difference was encountered in the rate of complete remission when using prophylaxis. Antifungal prophylaxis provides a lower risk of invasive fungal infections and in-hospital mortality in acute leukemia patients undergoing induction chemotherapy.

Abstract
Infections cause notable treatment-related morbidity during pediatric acute lymphoblastic leukemia/lymphoma (ALL/LLy) therapy. Infections are the most critical cause of morbidity and mortality in children undergoing treatment for acute lymphoblastic leukemia (ALL). Children with ALL, who are frequently underweight, are at increased risk of community-acquired pathogens, nosocomial multidrug-resistant pathogens, and opportunistic microorganisms. A weakened immune system from ALL itself and chemotherapy's side effects further worsen the prognosis. PubMed and Google Scholar articles were curated in a Google document with shared access. Discussion and development of the paper were achieved over Zoom meetings. This narrative review aims to analyze and summarize various pathogens responsible for infections in children receiving treatment for ALL and their treatment regimen and prophylaxis. The incidence of viral infection is higher in ALL patients, followed by bacterial and fungal infections. Prevention via prophylaxis and timely initiation of treatment is essential for positive outcomes.

Dufresne SF, Bergeron J, Beauchemin S, Abou Chakra CN, Vadnais B, Bouchard P, Labbé AC, Laverdière M. Real-life comparison of posaconazole versus fluconazole for primary antifungal prophylaxis during remission-induction chemotherapy for acute leukemia. JOURNAL OF THE ASSOCIATION OF MEDICAL MICROBIOLOGY AND INFECTIOUS DISEASE CANADA = JOURNAL OFFICIEL DE L'ASSOCIATION POUR LA MICROBIOLOGIE MEDICALE ET L'INFECTIOLOGIE CANADA 2023; 8:18-28. [PMID: 37008582 PMCID: PMC10052906 DOI: 10.3138/jammi-2022-0027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 10/23/2022] [Accepted: 11/03/2022] [Indexed: 06/19/2023]
Abstract
BACKGROUND Patients undergoing remission-induction intensive chemotherapy for acute leukemia are at high risk for life-threatening invasive fungal infections (IFIs). Primary antifungal prophylaxis with posaconazole has been shown to reduce the incidence of IFI compared to fluconazole, but real-life data are limited and the effect on mortality remains unclear. METHODS This retrospective cohort study compared fluconazole and posaconazole as primary prophylaxis in real-life practice over a 10-year period, in a Canadian hospital. RESULTS A total of 299 episodes were included (fluconazole, n = 98; posaconazole, n = 201), of which 68% were first inductions. The underlying hematologic malignancy was acute myeloid leukemia or myelodysplastic syndrome in 88% of episodes and acute lymphoblastic leukemia in 9%. Overall, 20 cases of IFI occurred (aspergillosis, n = 17; candidiasis, n = 3) and 14 were considered as breakthrough IFI. IFI incidence was significantly lower in the posaconazole group (3.5% versus 13.2%; p = 0.001). Empirical or targeted antifungal therapy was also reduced in the posaconazole cohort. Mortality was similar in both groups. CONCLUSIONS In a real-life setting in Canada, primary posaconazole prophylaxis reduces the incidence of IFI during remission-induction chemotherapy, compared to fluconazole.

Abstract
Abstract
Introduction Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Its outcome in India is not as good as that in the western world. One of the important reasons for lesser survival rates is opportunistic infections, including invasive fungal infections (IFIs). Antifungal prophylaxis (AFP) in ALL children is routinely not followed. However, owing to its incidence in high-risk ALL, this study is focused on the use of AFP in those children.
Objectives This retrospective study investigated the role of AFP in newly diagnosed children with high-risk ALL on intensive blocks of therapy on regimens B and C of the United Kingdom Acute Lymphoblastic Leukemia 2003 protocol.
Materials and Methods The study was conducted in a tertiary care center from 1st December 2013 to 31st December 2019 and included children with ALL from 1 to 18 years of age. Routine AFP with voriconazole was commenced for high-risk ALL children from 1st July 2017 onward in our center. We analyzed data of all IFIs in children before and after AFP with National Cancer Institute high-risk status who had been started on regimen B induction and regimen B or C consolidation and intensification phases.
Results A total of 55 children with high-risk ALL were included in the study. The median age was 4 years, with the majority being between the age of 1 and 10 years (38 out of 55; 65%) and predominantly male (36 out of 55; 69%). Total incidence of IFI in our cohort was 51% (28 out of 55). A significant number of children (16 out of 22 [70%]) who were not on prophylaxis developed IFI versus children (12 out of 33 [28%]) on prophylaxis (p = 0.008). The most common organisms isolated were Candida parapsilosis and Candida tropicalis. Children not receiving AFP were found to be 4.7 times (95% confidence interval: 1.44–15.13) more likely to get IFI than the ones receiving AFP. The presence of concurrent bacterial infection increases the risk of IFI (p = 0.04).
Conclusion The incidence of IFI was high in high-risk ALL children who were not on AFP. The introduction of routine AFP reduced the incidence of IFI.

J Cardiovasc Pharmacol 2022; 79:833-845. [PMID: 35266922 DOI: 10.1097/fjc.0000000000001258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Accepted: 02/26/2022] [Indexed: 11/25/2022]
Abstract
ABSTRACT Cytochrome P450 1B1 (CYP1B1) is known to be involved in the pathogenesis of several cardiovascular diseases, including cardiac hypertrophy and heart failure, through the formation of cardiotoxic metabolites named as mid-chain hydroxyeicosatetraenoic acids (HETEs). Recently, we have demonstrated that fluconazole decreases the level of mid-chain HETEs in human liver microsomes, inhibits human recombinant CYP1B1 activity, and protects against angiotensin II-induced cellular hypertrophy in H9c2 cells. Therefore, the overall purpose of this study was to elucidate the potential cardioprotective effect of fluconazole against cardiac hypertrophy induced by abdominal aortic constriction (AAC) in rats. Male Sprague-Dawley rats were randomly assigned into 4 groups such as sham control rats, fluconazole-treated (20 mg/kg daily for 4 weeks, intraperitoneal) sham rats, AAC rats, and fluconazole-treated (20 mg/kg) AAC rats. Baseline and 5 weeks post-AAC echocardiography were performed. Gene and protein expressions were measured using real-time PCR and Western blot analysis, respectively. The level of mid-chain HETEs was determined using liquid chromatography-mass spectrometry. Echocardiography results showed that fluconazole significantly prevented AAC-induced left ventricular hypertrophy because it ameliorated the AAC-mediated increase in left ventricular mass and wall measurements. In addition, fluconazole significantly prevented the AAC-mediated increase of hypertrophic markers. The antihypertrophic effect of fluconazole was associated with a significant inhibition of CYP1B1, CYP2C23, and 12-LOX and a reduction in the formation rate of mid-chain HETEs. This study demonstrates that fluconazole protects against left ventricular hypertrophy, and it highlights the potential repurposing of fluconazole as a mid-chain HETEs forming enzymes' inhibitor for the protection against cardiac hypertrophy.
