Abstract
Invasive fungal infections pose significant morbidity and mortality risks, particularly those caused by moulds. Available antifungal classes are limited by toxicities and are increasingly susceptible to resistance, particularly amongst challenging fungal pathogens. The purpose of this case series and literature review was to characterize the use of a high-dose lipid formulation of amphotericin B. A case series is presented including patients who received high-dose lipid formulation amphotericin B (≥7.5 mg/kg/day) between June 2012 and August 2021. Additionally, a systematic literature review was conducted by searching the PubMed database for English-language studies involving individuals who received high-dose amphotericin B therapy (≥7.5 mg/kg) using lipid formulations. Nine patients were included in the case series, receiving an average of 8.9 ± 1.3 mg/kg liposomal amphotericin B over a mean of 11.0 ± 10.8 days predominantly for mould infections including Mucorales, aspergillosis and Fusarium. The patients were primarily cared for in intensive care units, with varying treatment histories and outcomes. A total of 11 studies (n=260 patients) met inclusion criteria for the literature review. Responses to high-dose liposomal amphotericin B ranged from 8% to 100%, often showing favourable outcomes. High doses of liposomal amphotericin B were well tolerated both in the case series and in published literature, with serum creatinine changes being the most commonly reported adverse event. However, multi-patient studies continue to report less than favourable (range 8-62%) response rates. High-dose liposomal amphotericin B, either alone or in combination with other antifungal agents, might be a viable strategy for managing invasive fungal infections when few treatment choices exist. This article is part of the Challenges and strategies in the management of invasive fungal infections Special Issue: https://www.drugsincontext.com/special_issues/challenges-and-strategies-in-the-management-of-invasive-fungal-infections.

Zou J. Site-specific delivery of cisplatin and paclitaxel mediated by liposomes: A promising approach in cancer chemotherapy. ENVIRONMENTAL RESEARCH 2023; 238:117111. [PMID: 37734579 DOI: 10.1016/j.envres.2023.117111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 08/25/2023] [Accepted: 09/09/2023] [Indexed: 09/23/2023]
Abstract
The site-specific delivery of drugs, especially anti-cancer drugs has been an interesting field for researchers and the reason is low accumulation of cytotoxic drugs in cancer cells. Although combination cancer therapy has been beneficial in providing cancer drug sensitivity, targeted delivery of drugs appears to be more efficient. One of the safe, biocompatible and efficient nano-scale delivery systems in anti-cancer drug delivery is liposomes. Their particle size is small and they have other properties such as adjustable physico-chemical properties, ease of functionalization and high entrapment efficiency. Cisplatin is a chemotherapy drug with clinical approval in patients, but its accumulation in cancer cells is low due to lack of targeted delivery and repeated administration results in resistance development. Gene and drug co-administration along with cisplatin/paclitaxel have resulted in increased sensitivity in tumor cells, but there is still space for more progress in cancer therapy. The delivery of cisplatin/paclitaxel by liposomes increases accumulation of drug in tumor cells and impairs activity of efflux pumps in promoting cytotoxicity. Moreover, phototherapy along with cisplatin/paclitaxel delivery can increase potential in tumor suppression. Smart nanoparticles including pH-sensitive nanoparticles provide site-specific delivery of cisplatin/paclitaxel. The functionalization of liposomes can be performed by ligands to increase targetability towards tumor cells in mediating site-specific delivery of cisplatin/paclitaxel. Finally, liposomes can mediate co-delivery of cisplatin/paclitaxel with drugs or genes in potentiating tumor suppression. Since drug resistance has caused therapy failure in cancer patients, and cisplatin/paclitaxel are among popular chemotherapy drugs, delivery of these drugs mediates targeted suppression of cancers and prevents development of drug resistance. Because of biocompatibility and safety of liposomes, they are currently used in clinical trials for treatment of cancer patients. In future, the optimal dose of using liposomes and optimal concentration of loading cisplatin/paclitaxel on liposomal nanocarriers in clinical trials should be determined.

Abstract
Chronic disseminated candidiasis (CDC) occurs mostly in patients with acute hematologic malignancy and its clinical manifestations derive from immune reconstitution following neutrophil recovery. The aim of this study was to describe epidemiological and clinical characteristics of CDC and define risk factors for disease severity. Demographic and clinical data were collected from medical files of patients with CDC hospitalized in two tertiary medical centers in Jerusalem between 2005 and 2020. Associations between different variables and disease severity were evaluated, as well as characterization of Candida species. The study included 35 patients. CDC incidence slightly increased during study years and the average number of involved organs and disease duration was 3 ± 1.26 and 178 ± 123 days, respectively. Candida grew in blood in less than third of cases and the most common isolated pathogen was Candida tropicalis (50%). Histopathological or microbiological workup in patients who underwent an organ biopsy demonstrated Candida in about half of the patients. Nine months after starting antifungals, 43% of the patients still didn't have resolution of organ lesions in imaging modalities. Factors associated with protracted and extensive disease were prolonged fever prior to CDC and absence of candidemia. A C- Reactive Protein (CRP) cutoff level of 7.18 mg/dL was found to predict extensive disease. In conclusion, CDC incidence is increasing and the number of involved organs is higher than previously described. Clinical factors such as fever duration prior to CDC and absence of candidemia can predict severe course of disease and assist in treatment decisions and follow-up planning.

Abstract
Today, nanoscience has grown and developed in various fields of medicine and treatment, including cancer treatment. Currently, the existing treatments, including chemotherapy and radiotherapy, cause side effects that are unpleasant to the patient. Due to the fact that anticancer drugs cause severe and widespread side effects, liposomes are considered as new drug carriers to minimize the untimely destruction of the drug when it is delivered to the target tissue and to prevent the side effects of toxic drugs. This systematic review study examined the importance of using liposomes as new drug carriers for the delivery of genes and anticancer drugs. The articles published in English in the databases of Google scholar, WoS, PubMed, Embase, Scopus and science direct were reviewed. According to the results of this study, a new targeted nanosystem has been used for loading and delivering anticancer drugs, genes and controlled drug release which has a significant therapeutic effect compared to the same amount of free drug. In general, liposomal systems have been considered because of their capability in preserving the effect of the drug along with reducing the side effects and toxicity of the drug, especially in the case of anticancer drugs. Accumulation of the drug in a target tissue which results in a reduction of the drug entry into other tissues is the main reason for reducing the side effects of these drugs.

Abstract
Background Patients with acute myeloid leukemia (AML) are at risk of hepatosplenic candidiasis (HSC). HSC is often associated with prolonged fever and difficulty in definitive clinical diagnosis. We aimed to explore the incidence, clinical features, image findings and outcomes of HSC among patients with AML in a tertiary hospital, Taiwan. Methods We did a chart review of patient data in our institute from 2009 to 2012. The diagnosis of HSC was based on risk factors, febrile symptoms and image findings. Results Two hundred and ninety-two patients with AML were analyzed. In total, 1051 chemotherapy sessions were administered. Eleven patients (4 males and 7 females) experienced HSC (incidence 3.8%, 95% conference interval 2.11–6.72%). Among those with HSC, the median age was 62. Eight patients developed HSC following induction or re-induction chemotherapies. Three developed HSC following consolidation chemotherapies. The median duration of severe neutropenia was 25 days (range 10–142). In all patients with HSC, multiple hypodense lesions were found in the involved organs by computed tomography scans. Lesions consistent with HSC could be identified by ultrasound in 5 out of 6 patients. Other than liver and spleen, lung was frequently (7 cases) and kidney occasionally (3 cases) involved. Four patients died within 90 days. Prolonged neutropenia was associated with mortality. Conclusion HSC occurred more often during induction or re-induction periods. Lungs are commonly involved and pleural effusion was frequently seen in CT scans. Pleural effusion may suggest more serious infections but its clinical relevance should be investigated in large-scale studies. Prolonged neutropenia is the only prognostic factor. Prophylaxis should be considered. In the absence of prophylaxis, we advise early image studies and prompt antifungal treatment in patients at risk for HSC.

Abstract
In the last decades, pharmaceutical interested researches aimed to develop novel and innovative drug delivery techniques in the medical and pharmaceutical fields. Recently, phospholipid vesicles (Liposomes) are the most known versatile assemblies in the drug delivery systems. The discovery of liposomes arises from self-forming enclosed phospholipid bilayer upon coming in contact with the aqueous solution. Liposomes are uni or multilamellar vesicles consisting of phospholipids produced naturally or synthetically, which are readily non-toxic, biodegradable, and are readily produced on a large scale. Various phospholipids, for instance, soybean, egg yolk, synthetic, and hydrogenated phosphatidylcholine consider the most popular types used in different kinds of formulations. This review summarises liposomes composition, characterisation, methods of preparation, and their applications in different medical fields including cancer therapy, vaccine, ocular delivery, wound healing, and some dermatological applications.

Abstract
Abstract
Objectives
Despite its broad spectrum, conventional amphotericin B (AB) is associated with serious adverse events. Lipid-based formulations may offer safer options. We aimed to synthesize the evidence of efficacy and safety of AB formulations.
Methods
We performed a systematic review and network meta-analysis (NMA) to compare all available formulations: conventional AB; lipid complex or ABLC; colloidal dispersion or ABCD; liposomal or LAB; AB in Intralipid. Randomized controlled trials were searched in four databases. Cure, fever, chills, nephrotoxicity, death and drug discontinuation were assessed. NMA was based on Bayesian methods accounting for direct and indirect comparisons. Probability ranks estimating the best formulation were built for each outcome. The relative benefit–risk of formulations was assessed with stochastic multicriteria acceptability analyses (SMAA).
Key findings
We identified 25 trials (n = 2996). No significant differences among drugs were observed for cure or death. All lipid-based formulations were safer than conventional AB for nephrotoxicity. AB-Intralipid was more tolerable than conventional AB and caused less chills than ABCD. AB-Intralipid was the best therapy (>60%) regarding nephrotoxicity, fever, chills and discontinuation. The scenario from SMAA favoured AB-Intralipid (81% acceptability). Conventional AB was secondary to all lipid-based formulations.
Conclusions
Amphotericin B-Intralipid was identified as safer, cost-saving treatment in comparison with other formulations.

Abstract
The enzyme β-1,3-glucan synthase, which catalyzes the synthesis of β-1,3-glucan, an essential and unique structural component of the fungal cell wall, has been considered as a promising target for the development of less toxic anti-fungal agents. In this study, a robust pharmacophore model was developed and structure activity relationship analysis of 42 pyridazinone derivatives as β-1,3-glucan synthase inhibitors were carried out. A five-point pharmacophore model, consisting of two aromatic rings (R) and three hydrogen bond acceptors (A) was generated. Pharmacophore based 3D-QSAR model was developed for the same reported data sets. The generated 3D-QSAR model yielded a significant correlation coefficient value (R2 = 0.954) along with good predictive power confirmed by the high value of cross-validated correlation coefficient (Q2 = 0.827). Further, the pharmacophore model was employed as a 3D search query to screen small molecules database retrieved from ZINC to select new scaffolds. Finally, ADME studies revealed the pharmacokinetic efficiency of these compounds.
