A Review of the Safety of Interleukin-17A Inhibitor Secukinumab. Pharmaceuticals (Basel) 2022; 15:ph15111365. [PMID: 36355537 PMCID: PMC9695424 DOI: 10.3390/ph15111365] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 10/28/2022] [Accepted: 11/02/2022] [Indexed: 11/09/2022] Open
Abstract
Secukinumab is an anti-interleukin (IL)-17A IgG1-κ monoclonal antibody approved for psoriasis, psoriatic arthritis, and ankylosing spondylitis. Its efficacy is well documented, but the complete safety profile of secukinumab, especially on long-term use, needs to be studied. IL-17 inhibitors increase the risk of infections, especially respiratory tract infections and candidiasis, and inflammatory bowel disease; the causal relationships are well described. However, evidence regarding the other adverse events is scarce, and causal associations between the adverse events and the biologic remain unresolved. This review aims to present a narrative perspective on the safety of secukinumab and identify some key areas where the safety of secukinumab may potentially be useful in understanding the scope of secukinumab therapy and making informed clinical decisions.

Characteristics and Outcomes of Bloodstream Infections in a Tertiary-Care Pediatric Hematology-Oncology Unit: A 10-Year Study. J Clin Med 2022; 11:jcm11030880. [PMID: 35160334 PMCID: PMC8836920 DOI: 10.3390/jcm11030880] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 01/24/2022] [Accepted: 02/03/2022] [Indexed: 12/21/2022] Open
Abstract
Bloodstream infections (BSIs) after chemotherapy or hematopoietic stem cell transplantation (HSCT) are a leading cause of morbidity and mortality. Data on 154 BSIs that occurred in 111 onco-hematological patients (57 hematological malignancies, 28 solid tumors, and 26 non-malignant hematological diseases) were retrospectively collected and analyzed. Monomicrobial Gram-positive (GP), Gram-negative (GN), and fungal BSIs accounted for 50% (77/154), 38.3% (59/144), and 3.2% (5/154) of all episodes. Polymicrobial infections were 7.8% (12/154), while mixed bacterial-fungal infections were 0.6% (1/154). The most frequent GN isolates were Escherichia coli (46.9%), followed by Pseudomonas aeruginosa (21.9%), Klebsiella species (18.8%), and Enterobacter species (6.3%). Overall, 18.8% (12/64) of GN organisms were multidrug-resistant (seven Escherichia coli, three Klebsiella pneumoniae, and two Enterobacter cloacae), whereas GP resistance to glycopeptides was observed in 1% (1/97). Initial empirical antibiotic therapy was deemed inappropriate in 12.3% of BSIs (19/154). The 30-day mortality was 7.1% (11/154), while the bacteremia-attributable mortality was 3.9% (6/154). In multivariate analysis, septic shock was significantly associated with 30-day mortality (p = 0.0001). Attentive analysis of epidemiology and continuous microbiological surveillance are essential for the appropriate treatment of bacterial infections in pediatric onco-hematological patients.

Abstract
Background The main causes of mortality in patients with acute leukemia are the infectious complications. The author wanted to know the induction-related mortality and treatment-related mortality in the acute leukemia patients at the Instituto Nacional de Cancerologia (INCan), Mexico. Also the author is interested in finding out the micro-organism and the main site of infection to make some changes in the management of patients in these clinics. Primary objective was induction chemotherapy-related mortality and treatment-related mortality. Secondary objective was to determine the site of infection, micro-organism, type of chemotherapy related with more mortality and relapse mortality. Methods This was a retrospective case-series analysis of all patients who were admitted to the INCan Acute Leukemia Clinic between January 2012 and December 2015 with febrile neutropenic complications. We reviewed the case histories of all patients, including those with acute lymphoblastic leukemia (ALL), acute myeloblastic leukemia (AML), acute biphenotypic leukemia and acute promyelocytic leukemia, regardless of disease status (newly diagnosed or relapsed) at the time of clinic attendance. Patients who died as the result of an infectious complication during the analysis window were identified, and their demographics, disease characteristics, treatment history (chemotherapy within 45 days of date of death) and details of the infectious complication resulting in death were collected. Results Of the 313 patients studied during that time period, 84 (27%) died as a result of infectious complications. Lung infections were the most common, accounting for 67% of all deaths from infectious complications. Escherichia coli producing extended-spectrum beta-lactamases was the most frequently isolated infectious organism (12 patients; 14%). The majority of deaths occurred during either induction therapy (27 patients; 32%) or treatment for a first relapse (25 patients; 30%). Hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone (hyper-CVAD) was the chemotherapy regimen most commonly received within 45 days prior to death (17 patients; 20%). Conclusions Our findings suggest a need for long-term management and supportive care to prevent infectious complication-associated fatalities during both initial chemotherapy and subsequent disease relapse in patients with acute leukemia. The use of prophylaxis will help patients to prevent complications.

Abstract
INTRODUCTION Febrile neutropenia represents one of the most common treatment-associated complications in the management of acute myeloid leukemia (AML) and is considered an oncologic emergency. Rapid and detailed workup as well as the initiation of empiric broad-spectrum antibiotic therapy are critical to avoid sepsis and to reduce mortality. Although a definitive source of infection is frequently not identified, the severely immunosuppressed status of the AML patient undergoing cytotoxic therapy results in a high risk for a wide array of bacterial, fungal, and viral etiologies. AREAS COVERED The authors herein review the diagnostic and therapeutic approach to the neutropenic leukemia patient based on the current knowledge. Special consideration is given to the rapidly changing therapeutic landscape in AML, creating new challenges in the management of infectious complications. EXPERT OPINION Multidrug-resistant organisms pose a major challenge in the management of neutropenic fever patients with hematologic malignancies - including AML. Future directions to improve outcomes demand innovative treatment approaches as well as advances in biomarker research to facilitate diagnosis and disease monitoring. Recent achievements in AML-targeted therapy led to an increased incidence of differentiation syndrome, a potentially life-threatening side effect that frequently resembles clinical infection and requires prompt recognition and aggressive intervention.

Abstract
Background In sub-Saharan Africa where sickle cell trait (SCT) and malaria is prevalent, significant proportions of blood donors may be affected by one or more of these abnormalities. The haemato-biochemical properties of SCT and asymptomatic malaria in donor blood have not been evaluated. This study evaluated the haemato-biochemical impact of SCT and asymptomatic malaria infections in citrate-phosphate-dextrose-adenine (CPDA-1) stored donor blood units. Methods Fifty-milliliters of sterile CPDA-1 anti-coagulated blood were drained into the sample pouch attached to the main blood bag. Ten units each of sickle cell/malaria negative, sickle cell and malaria positive blood were analyzed. Baseline and weekly haematological profiling and week 1, 3 and 5 concentrations of plasma haemoglobin, % haemolysis, sodium, potassium and chloride and lactate dehydrogenase (LDH) were assayed. Differences between baseline and weekly data were determined using one-way analysis of variance (ANOVA) and Kruskal-Wallis test, whereas differences between baseline parameters and week 1-3 data pairs were determined using paired t-test. P-value < 0.05 was considered statistically significant. Results Storage of SCT and malaria infected blood affected all haematological cell lines. In the SCT donors, red blood cells (RBC) (4.75 × 1012/L ± 1.43baseline to 3.49 × 1012/L ± 1.09week-5), haemoglobin (14.45 g/dl ± 1.63baseline to 11.43 g/dl ± 1.69week-5) and haematocrit (39.96% ± 3.18baseline to 33.22% ± 4.12week-5) were reduced. In the asymptomatic malaria group, reductions were observed in RBC (5.00 × 1012/L ± 0.75baseline to 3.72 × 1012/L ± 0.71week-5), haemoglobin (14.73 g/dl ± 1.67baseline to 11.53 g/dl ± 1.62week-5), haematocrit (42.72% ± 5.16baseline to 33.38% ± 5.80week-5), mean cell haemoglobin concentration (35.48 g/dl ± 1.84baseline to 35.01 g/dl ± 0.64week-5) and red cell distribution width coefficient of variation (14.81% ± 1.54baseline to 16.26% ± 1.37week-5). Biochemically, whereas plasma LDH levels significantly increased in asymptomatic malaria blood donors (319% increase at week 5 compared to baseline), SCT blood donors had the most significant increase in plasma potassium levels at week 5 (382% increase). Sodium ions significantly reduced in SCT/malaria negative and sickle cell trait blood at an average rate of 0.21 mmol/L per day. Moreover, elevations in lymphocytes-to-eosinophils and lymphocytes-to-neutrophils ratios were associated with SCT and malaria positive blood whilst elevation lymphocytes-to-basophils ratio was exclusive to malaria positive blood. Conclusion Severe storage lesions were significant in SCT or malaria positive donor blood units. Proper clinical evaluation must be done in prospective blood donors to ensure deferral of such donors.

Abstract
Febrile neutropenic patients are at a high risk of life-threatening bacterial infections. Tigecycline was developed to treat multidrug-resistant isolates, however resistance to tigecycline in Klebsiella pneumoniae has been reported. Here, we investigated tigecycline resistance among K. pneumoniae isolated from febrile neutropenic patients admitted to Hematology ICU, Egypt. Out of 75 enrolled febrile neutropenic patients, 48 cases showed bacteriologically confirmed infection. The majority of cases were infected with K. pneumoniae, of which nine were tigecycline non-susceptible. Expression levels of the efflux pump genes acrB and oqxB and their regulatory genes ramA and rarA were analysed. Six isolates had overexpression of the four efflux-related genes while one showed baseline expression. This study emphasizes the importance of growing tigecycline resistance in K. pneumoniae infecting febrile neutropenic patients. Concerning the mechanism of resistance, it was clear that the ramA gene plays the major role, although alternative resistance mechanisms may also exist.

Abstract
BACKGROUND We aimed to identify the impact of the presence of neutropenia on serum vancomycin concentration (SVC). METHODS A retrospective study was conducted from January 2005 to December 2015. The study population was comprised of adult patients who were performed serum concentration of vancomycin. Patients with renal failure or using non-conventional dosages of vancomycin were excluded. RESULTS A total of 1307 adult patients were included in this study, of whom 163 (12.4%) were neutropenic. Patients with neutropenia presented significantly lower SVCs than non-neutropenic patients (P<0.0001). Multiple linear regressions showed significant association between neutropenia and trough SVC (beta coefficients, -2.351; P=0.004). Multiple logistic regression analysis also revealed a significant association between sub-therapeutic vancomycin concentrations (trough SVC values<10mg/l) and neutropenia (odds ratio, 1.75, P=0.029) CONCLUSIONS: The presence of neutropenia is significantly associated with low SVC, even after adjusting for other variables. Therefore, neutropenic patients had a higher risk of sub-therapeutic SVC compared with non-neutropenic patients. We recommended that vancomycin therapy should be monitored with TDM-guided optimization of dosage and intervals, especially in neutropenic patients.

Abstract
Fever of unknown origin (FUO) remains a challenging clinical problem, namely in patients with cancer. In cancer patients, FUO may be due to the cancer itself, as it is the case of hematological malignancies; digestive tumors (colon cancer, liver metastases) are significantly associated with FUO and infection can be demonstrated in some cases. Prevention with G-CSF and empirical antimicrobial therapy are essential approaches for the management of FUO in cancer patients. New diagnostic approaches, such as PET imaging, should be further evaluated in cancer patients with FUO.

Abstract
Introduction The aim of this analysis was to describe in real-world settings the clinical outcomes and safety associated with daptomycin treatment in patients with neutropenia and Gram-positive infections. Methods Patients with an absolute neutrophil count (ANC) ≤1000 cells/mm3 who received at least one dose of daptomycin between 2006 and 2012 were selected from a non-interventional, multicenter, retrospective registry (European Cubicin® Outcome Registry and Experience; EU-CORESM). Results Of the 6075 patients enrolled in EU-CORE, 446 (7.3%) had an ANC ≤ 1000 cells/mm3 at baseline or during daptomycin therapy; they were all included in efficacy and safety populations. Half of the patients had severe neutropenia (ANC ≤ 100 cells/mm3). Most patients had hematologic malignancy (60.5%), an immunosuppressed state (39.7%) or had undergone a transplant (27.8%). The most common primary infections were bacteremia (42.2%) and complicated skin and soft tissue infection (13.9%). Cultures were positive for 68.6% (254/370) of patients with available culture results; coagulase-negative staphylococci (43.7%; 111/254) and Staphylococcus aureus (18.9%; 48/254) were the most commonly isolated primary pathogens. Median duration of daptomycin therapy was 10.0 (range 1–98) days. Most patients (82.8%) received antibiotics concomitantly with daptomycin; the most common were carbapenems (51.2%), penicillins (42.1%), and aminoglycosides (19.9%). The overall clinical success rate (cured or improved) associated with daptomycin was 77.1%. Adverse events possibly related to daptomycin treatment were reported in seven (1.6%) patients and led to drug discontinuation in 27 (6.1%) patients. Conclusion The study results suggest that daptomycin is an effective therapeutic option for the treatment of a broad range of Gram-positive infections in patients with neutropenia, and has a good safety profile.

Abstract
Antimicrobial treatment is often indicated to neutropenic patients. Although renal failure is a common complication of many antibiotics, no information could be found in the literature defining which are the best screening criteria for detecting renal injury. In this paper, the authors aim to assess the progress to renal failure in neutropenic patients on antimicrobial use and to compare different diagnostic criteria of renal failure in association to antimicrobial agents used. This is a cohort study conducted from February to August 2006 at the Hospital das Clínicas of the Universidade Federal de Minas Gerais, which included patients with neutropenia and antimicrobial therapy for the treatment of Healthcare Associated Infections notified by the Hospital Infection Control Committee. Renal injury has ensued in 25% of patients and no statistical difference between distinct criteria for renal injury was observed. Association of greater number of antimicrobials was associated with renal impairment. Time required for renal injury was independent of the antimicrobial regimen used, but mortality among patients with renal injury was higher when compared to those who had preserved renal function.

Abstract
Patients with a hematological malignancy are a heterogeneous patient population who are afflicted with diseases that range from rapidly fatal acute leukemia to indolent lymphoma or chronic leukemia. Treatment options for these patients range from observation to hematopoietic stem cell transplantation (HSCT), but all patients are more susceptible to infection. The problem of infection is dynamic with continued shifts in pathogenic organisms and microbial susceptibilities, new treatment regimens that further diminish immune function, and patients receiving treatment who are now older and frailer. The classic patterns of immunodeficiency for patients with a hematological malignancy include: periods of profound neutropenia, increased iatrogenic risks (i.e., central vascular catheters), and cellular immune suppression that affects HSCT recipients, patients with lymphoid malignancies, and those receiving treatment with corticosteroids or agents like alemtuzumab [1–4]. Recent advances in antimicrobial drug development, new technology, clinical trial results, and further clinical experience have enhanced the database on which to make infection prophylaxis and treatment decisions. However, the practicing clinician must remember that the majority of basic infection management principles for patients who are neutropenic remain unchanged.

Abstract
OBJECTIVE The aim of this study was to analyze the characteristics and infectious complications of neutropenic patients in a referral hospital. METHODS A cross-sectional study was carried out between April and September 2008, which enrolled all neutropenic patients identified by daily blood counts in the Universidade Federal de Minas Gerais. Demographic data and information on infections were obtained from the Hospital Infection Control Committee. Statistical analysis was performed using the Statistical Package for Social Sciences. RESULTS One hundred and sixteen patients were followed up during 129 hospitalizations. The patients had a mean age of 48.7 years old. Sixty-four (55.2%) patients were male and 25 (21.6%) died during the follow-up. In 97 (75.2%) of the hospitalizations, patients had episodes of febrile neutropenia. Patients classified as low-risk had a mortality rate of 16.2% (n = 12) vs. 39.1% (n = 9) among high-risk patients (p-value = 0.02). The death rate of the patients who had been submitted to hematopoietic stem cell transplantation was 13.5% (n = 5) vs. 26.7% (n = 16) among patients not submitted to transplantation (p-value = 0.13). Of the 155 infections diagnosed, 45.5% were defined as clinically documented. The etiological agent most frequently isolated was Escherichia coli and the main topography reported was bloodstream infections. The most used antimicrobial agents were cefepime, vancomycin and fluconazole. Approximately 24% of patients evolved with impaired renal function during hospitalization. CONCLUSION Most reported infections in neutropenic patients were defined as clinically documented, which shows the importance of suspicion in patients without specific signs and symptoms for early diagnosis and the need for the classification of risk for timely interventions.

Abstract
This document updates and expands the initial Infectious Diseases Society of America (IDSA) Fever and Neutropenia Guideline that was published in 1997 and first updated in 2002. It is intended as a guide for the use of antimicrobial agents in managing patients with cancer who experience chemotherapy-induced fever and neutropenia. Recent advances in antimicrobial drug development and technology, clinical trial results, and extensive clinical experience have informed the approaches and recommendations herein. Because the previous iteration of this guideline in 2002, we have a developed a clearer definition of which populations of patients with cancer may benefit most from antibiotic, antifungal, and antiviral prophylaxis. Furthermore, categorizing neutropenic patients as being at high risk or low risk for infection according to presenting signs and symptoms, underlying cancer, type of therapy, and medical comorbidities has become essential to the treatment algorithm. Risk stratification is a recommended starting point for managing patients with fever and neutropenia. In addition, earlier detection of invasive fungal infections has led to debate regarding optimal use of empirical or preemptive antifungal therapy, although algorithms are still evolving. What has not changed is the indication for immediate empirical antibiotic therapy. It remains true that all patients who present with fever and neutropenia should be treated swiftly and broadly with antibiotics to treat both gram-positive and gram-negative pathogens. Finally, we note that all Panel members are from institutions in the United States or Canada; thus, these guidelines were developed in the context of North American practices. Some recommendations may not be as applicable outside of North America, in areas where differences in available antibiotics, in the predominant pathogens, and/or in health care-associated economic conditions exist. Regardless of venue, clinical vigilance and immediate treatment are the universal keys to managing neutropenic patients with fever and/or infection.

Abstract
This study was undertaken to investigate the synergistic interaction between amphotericin B (AmB) and acteoside, isolated from the aerial parts of the shrub Colebrookea oppositifolia (Lamiaceae). Acteoside alone exhibited no intrinsic antifungal activity but showed a potent synergism in combination with AmB against selected pathogenic species, with fractional inhibitory concentration indices in the range of 0.0312-0.1562. The combination of acteoside at 3.12 and 12.5 µg ml(-1) with subinhibitory concentrations of AmB resulted in a potent fungicidal effect and also exhibited a significantly extended post-antifungal effect. Furthermore, the combination also reduced the minimum biofilm reduction concentration values of AmB (2-16-fold) in preformed biofilms of Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus. There was decreased viability of the cells, increased uptake of propidium iodide and enhanced leakage of 260 nm-absorbing material by Candida albicans cells when exposed to AmB in the presence of acteoside. The reason for potentiation is likely to be that the subinhibitory concentrations of AmB facilitated the uptake of acteoside, which resulted in increased killing of the fungal cells. Administration of acteoside in mice at up to 2000 mg (kg body weight)(-1) by the intraperitoneal or oral route produced no overt toxicity. The data presented here support synergism between acteoside and AmB, and it is therefore proposed that a prospective new management strategy for therapeutic application of this combination should be explored.

Abstract
BACKGROUND Guidelines advocate >7d of broad-spectrum antibiotics for unexplained fever (UF) during neutropaenia. However, effective antimicrobial prophylaxis reduces the incidence of gram-negative infections, which may allow shorter treatment. This study evaluates the safety of discontinuing empirical broad-spectrum antibiotics if no microbial source is documented after an initial work-up of 72 h. METHODS Prospective observational study at a tertiary-care haematology-unit in patients suffering from haematologic malignancies and treatment-induced prolonged neutropaenia of 10d. Oral fluoroquinolone and fluconazole prophylaxis was given from day 1. Fever was empirically treated with imipenem which was discontinued after 72 h if, following a standardised protocol, no infectious aetiology was documented. Duration of fever, antimicrobial therapy and overall mortality were registered. RESULTS One hundred and sixty six patients were evaluated during 276 neutropaenic episodes. One hundred and thirty six patients (82.5%) experienced 1 febrile episode. A total of 317 febrile episodes were observed, of which 177 (56%) were diagnosed as UF. In 135 febrile episodes (43%), a probable/definite infectious origin was documented. Mean duration of fever in neutropaenic periods with 1 febrile episode was 5d, and mean time of treatment with imipenem was 4.7d. In patients without documented infection, mean time of imipenem treatment was only 3.7d. Overall mortality 30 d after neutrophil recovery was 3.6% (6/166); no patient died from untreated bacterial infection. CONCLUSION Discontinuation of broad-spectrum antibiotics during neutropaenia in haematology patients on fluoroquinolone and fluconazole prophylaxis is safe, provided that no infectious aetiology is established after 72 h.

Abstract
Recent years have seen the release of multiple new systemic antifungal agents, significantly increasing options for the treatment of most serious fungal infections. Newly available drugs include those in the echinocandin class, including caspofungin, micafungin, and anidulafungin, as well as the newer generation triazoles, voriconazole and posaconazole. Ordering of these agents is variably restricted, depending on a given institution's policies, and all are costly. In this review we examine the available evidence and outline the role of newer antifungal medications in several common and/or important situations, including invasive and mucocutaneous Candida infection, febrile neutropenia, invasive aspergillosis, zygomycosis, and endemic mycoses.

Isobolographic analysis of pharmacodynamic interactions between antifungal agents and ciprofloxacin against Candida albicans and Aspergillus fumigatus. Antimicrob Agents Chemother 2008; 52:2196-204.

Abstract
Patients suffering from invasive mycoses often receive concomitant antifungal therapy and antibacterial agents. Assessment of pharmacodynamic interactions between antifungal and antibacterial agents is complicated by the absence of a common antifungal end point for both agents. Ciprofloxacin has no intrinsic antifungal activity but may interact with antifungal agents, since it inhibits DNA gyrase (topoisomerase II), which is abundant in fungi. We therefore employed isobolographic analysis adapted to incorporate a nonactive agent in order to analyze the potential in vitro interaction between the fluoroquinolone ciprofloxacin and several representative antifungal agents against Candida albicans and Aspergillus fumigatus strains by using a microdilution checkerboard technique. In agreement with earlier in vitro studies, conventional fractional inhibitory concentration index analysis was unable to detect interactions between ciprofloxacin and antifungal agents. However, isobolographic analysis revealed significant pharmacodynamic interactions between antifungal agents and ciprofloxacin against C. albicans and A. fumigatus strains. Amphotericin B demonstrated concentration-dependent interactions for both species, with synergy (interaction indices, 0.14 to 0.81) observed at ciprofloxacin concentrations of <10.64 microg/ml. Synergy (interaction indices, 0.10 to 0.86) was also found for voriconazole and caspofungin against A. fumigatus. Isobolographic analysis may help to elucidate the pharmacodynamic interactions between antifungal and non-antifungal agents and to develop better management strategies against invasive candidiasis and aspergillosis.
