Khan MSA. Synergistic Interaction of Certain Essential Oils and Their Active Compounds with Fluconazole against Azole-resistant Strains of Cryptococcus neoformans. Ann Afr Med 2024; 23:391-399. [PMID: 39034564 DOI: 10.4103/aam.aam_197_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 02/26/2024] [Indexed: 07/23/2024] Open
Abstract
OBJECTIVES This study investigated the anti-cryptococcal potential of certain essential oils (EOs)/compounds alone and in combination with fluconazole. MATERIALS AND METHODS We investigated the antifungal activity of oils of Cinnamomum verum, Cymbopogon citratus, Cymbopogon martini, and Syzygium aromaticum, and their major active ingredients cinnamaldehyde, citral, eugenol, and geraniol against clinical and standard strains of Cryptococcus neoformans (CN). Disc diffusion, broth microdilution, checkerboard methods, and transmission electron microscopy were employed to determine growth inhibition, synergistic interaction, and mechanism of action of test compounds. RESULTS EOs/compounds showed pronounced antifungal efficacy against azole-resistant CN in the order of cinnamaldehyde > eugenol > S. aromaticum > C. verum > citral > C. citratus > geraniol ≥ C. martini, each exhibiting zone of inhibition >15 mm. These oils/compounds were highly cidal compared to fluconazole. Eugenol and cinnamaldehyde showed the strongest synergy with fluconazole against CN by lowering their MICs up to 32-fold. Transmission electron microscopy indicated damage of the fungal cell wall, cell membrane, and other endomembranous organelles. CONCLUSION Test oils and their active compounds exhibited potential anti-cryptococcus activity against the azole-resistant strains of CN. Moreover, eugenol and cinnamaldehyde significantly potentiated the anti-cryptococcal activity of fluconazole. It is suggested that multiple sites of action from oils/compounds could turn static fluconazole into a cidal drug combination in combating cryptococcosis.

Abstract
Invasive fungal disease (IFD) during neutropenia goes along with a high mortality for patients after allogeneic hematopoietic cell transplantation (alloHCT). Low-dose computed tomography (CT) thorax shows good sensitivity for the diagnosis of IFD with low radiation exposure. The aim of our study was to evaluate sequential CT thorax scans at two time points as a new reliable method to detect IFD during neutropenia after alloHCT. We performed a retrospective single-center observational study in 265/354 screened patients admitted for alloHCT from June 2015 to August 2019. All were examined by a low-dose CT thorax scan at admission (CT t0) and after stable neutrophil recovery (CT t1) to determine the incidences of IFD. Furthermore, antifungal prophylaxis medications were recorded and cohorts were analyzed for statistical differences in IFD incidence using the sequential CT scans. In addition, IFD cases were classified according to EORTC 2008. At CT t0 in 9.6% of the patients, an IFD was detected and antifungal therapy initiated. The cumulative incidence of IFD in CT t1 in our department was 14%. The use of Aspergillus-effective prophylaxis through voriconazole or posaconazole decreased CT thorax t1 suggesting IFD is statistically significant compared to prophylaxis with fluconazole (5.6% asp-azol group vs 16.3% fluconazole group, p = 0.048). In 86%, CT t1 was negative for IFD. Low-dose sequential CT thorax scans are a valuable tool to detect pulmonary IFDs and guide antifungal prophylaxis and therapies. Furthermore, a negative CT t1 scan shows a benefit by allowing discontinuation of antifungal medication sparing patients from drug interactions and side effects.

Abstract
OBJECTIVE To assess the impact of cytochrome P450 (CYP) 2C19 polymorphisms on the clinical efficacy and safety of voriconazole. METHODS We systematically searched PubMed, EMBASE, CENTRAL, ClinicalTrials.gov, and three Chinese databases from their inception to 18 March 2021 using a predefined search algorithm to identify relevant studies. Studies that reported voriconazole-treated patients and information on CYP2C19 polymorphisms were included. The efficacy outcome was success rate. The safety outcomes included overall adverse events, hepatotoxicity, and neurotoxicity. RESULTS A total of 20 studies were included. Intermediate metabolizers (IMs) and poor metabolizers (PMs) were associated with increased success rates compared with normal metabolizers (NMs) [risk ratio (RR), 1.18; 95% confidence interval (CI), 1.03-1.34; I2 = 0%; P = 0.02; RR, 1.28; 95% CI, 1.06-1.54; I2 = 0%; P = 0.01]. PMs were at increased risk of overall adverse events in comparison with NMs and IMs (RR, 2.18; 95% CI, 1.35-3.53; I2 = 0%; P = 0.001; RR, 1.80; 95% CI, 1.23-2.64; I2 = 0%; P = 0.003). PMs demonstrated a trend towards an increased incidence of hepatotoxicity when compared with NMs (RR, 1.60; 95% CI, 0.94-2.74; I2 = 27%; P = 0.08), although there was no statistically significant difference. In addition, there was no significant association between CYP2C19 polymorphisms and neurotoxicity. CONCLUSION IMs and PMs were at a significant higher success rate in comparison with NMs. PMs were significantly associated with an increased incidence of all adverse events compared with NMs and IMs. Researches are expected to further confirm these findings. Additionally, the relationship between hepatotoxicity and CYP2C19 polymorphisms deserves clinical attention.

Abstract
Abstract
Background
Invasive fungal diseases (IFD) remain a major complication of allogeneic hematopoietic stem cell transplantation (alloHSCT) and are associated with high mortality rates in patients receiving alloHSCT. Antifungal prophylaxis is increasingly being used in the management of IFDs in patients receiving alloHSCT.
Methods
A post-hoc analysis of the cross-sectional observational AFHEM study was carried out to describe the use of antifungal drugs in real-life clinical practice in alloHSCT recipients hospitalized in French hematological units.
Results
A total of 147 alloHSCT recipients were enrolled; most were adults (n = 135; 92%) and had received alloHSCT < 6 months prior to enrollment (n = 123; 84%). Overall, 119 (81%) patients received a systemic antifungal therapy; of these, 95 (80%) patients received antifungal prophylaxis. Rates of patients receiving systemic antifungal treatment were similar irrespective of transplant time, neutropenic, and graft-versus-host disease status. Among patients on systemic antifungal treatment, 83 (70%) received an azole, 22 (18%) received an echinocandin, and 16 (13%) received a polyene.
Conclusions
This work provides evidence of the antifungal strategies used in alloHSCT recipients hospitalized in French hematological units. Unlike earlier studies, the AFHEM study showed that prophylaxis appears to be the leading antifungal strategy used in alloHSCT recipients in France.

Abstract
OBJECTIVE Fluconazole or posaconazole is a standard of care in antifungal prophylaxis for patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). However, many patients need to interrupt standard prophylaxis due to intolerability, drug-drug interactions, or toxicity. Micafungin has come to prominence for these patients. However, the optimal biological dose of micafungin stays unclear. METHODS We retrospectively evaluated the efficacy of micafungin as antifungal prophylaxis in HSCT patients. Micafungin was applied as bridging in patients who were not eligible to receive oral posaconazole. Micafungin was either given at a dose of 100 mg or 50 mg SID. RESULTS A total of 173 patients received micafungin prophylaxis, 62 in the 100 mg and 111 in the 50 mg dose group. The incidence of probable or proven breakthrough IFDs during the observation period was one in the 100 mg and one in the 50 mg group. Fungal-free survival after 100 days was 98% and 99% (P = .842), and overall survival after 365 days was 60% and 63% (P = .8) respectively. In both groups, micafungin was well tolerated with no grade 3 or 4 toxicities. CONCLUSION In this retrospective analysis, which was not powered to detect non-inferiority, micafungin is effective and complements posaconazole as fungal prophylaxis in HSCT.

Abstract
OBJECTIVE To improve the clinical understanding of fungal esophagitis in patients with hematologic malignancies. METHOD The clinical data of a cohort of 279 patients with hematologic malignancies who underwent gastroscopy between 2012 and 2015 in the Endoscopy Center of Henan Tumor Hospital were retrospectively analyzed. To investigate the clinical characteristics and prognosis of fungal esophagitis in patients with heratologic malignancies. RESULTS 13 of the 279 patients were diagnosed as fungal esophagitis (4.66% ). C. albicans was prevalent (12/13), and only 1 case was cryptococcus. All of the 13 patients had lymphatic systemic diseases (8 cases with diffuse large B cell lymphoma, 1 with peripheral T-cell lymphoma, 2 with acute lymphoblastic leukemia, and 1 with multiple myeloma). 6 patients had gastrointestinal symptoms (3 cases with nausea and anorexia as well as the sentation of having a foreign body in pharyngeal, 2 cases with pain or a burning sensation behind the sternum, and 1 case having difficulty or pain when swallowing), while 7 patients had no obvious manifestations. 6 patients accepted fluconazole 400 mg/d for 2 weeks and achieved satisfactory results; Meanwhile 7 cases were given nystatin 1 million uint 3 times a day for 2 weeks, of which 6 cases responded well, and 1 case was not relieved until he was given fluconazole 400 mg/d for 1 week. Treatmentassociated adverse events included mildly elevated aminotransferase (1 case) and mild gastrointestinal adverse reaction (1 case). CONCLUSION The fungal esophagitis in patients with hematologic malignancies was not rare. Most of those patients had lymphatic systemic diseases and the main pathogen was candida albicans. The clinical manifestations of fungal esophagitis were quite atypical and about more than half of those patients had no gastrointestinal symptoms. Either fluconazole or nystatin was safe and effective treatment with slight adverse reactions.

Abstract
Invasive fungal infections are a major cause of morbidity and mortality in patients with hematopoietic stem cell transplantation. A prospective multicenter post-marketing observational surveillance study was conducted from July 2007 to June 2010 to assess the safety and efficacy of micafungin, an echinocandin antifungal, for prophylaxis against invasive fungal infections in Japanese patients undergoing hematopoietic stem cell transplantation. Among 241 patients evaluated for safety, 143 adverse drug reactions were reported in 86 patients (35.7%), with hepatobiliary disorders the most frequently reported adverse drug reactions. The success rate for prophylaxis at the end of observation was 72.8% (131/180 patients), and the incidence of breakthrough infections was only 4.4% (8/180 patients). In conclusion, micafungin had sufficient safety and efficacy for prophylaxis against invasive fungal infections in Japanese patients with various backgrounds undergoing hematopoietic stem cell transplantation.

Abstract
The objective of this study was to evaluate the efficacy and safety of micafungin for the prevention of invasive fungal infection (IFI) during the neutropenic phase of allogeneic hematopoietic SCT (allo-HSCT) in children and adolescents. This was a prospective, multicenter, open-label, single-arm study. Micafungin was administered i.v. at a dose of 1 mg/kg/day (max 50 mg) from the beginning of conditioning until neutrophil engraftment. Treatment success was defined as the absence of proven, probable, possible or suspected IFI through to 4 weeks after therapy. From April 2010 to December 2011, 155 patients were enrolled from 11 institutions in Korea, and 147 patients were analyzed. Of the 147 patients, 121 (82.3%) completed the protocol without premature interruption. Of the 132 patients in whom micafungin efficacy could be evaluated, treatment success was achieved in 119 patients (90.2%). There was no proven fungal infection in any patient. The number of patients with probable, possible and suspected IFI was two, two and nine, respectively. Thirty-five patients (23.8%) experienced 109 adverse events (AEs) possibly related to micafungin. No patients experienced grade IV AEs. Two patients (1.4%) discontinued micafungin administration due to adverse effects. None of the deaths were related to the study drug.

Abstract
PURPOSE The cost-effectiveness of voriconazole versus fluconazole prophylaxis against fungal infections in hematopoietic cell transplant (HCT) recipients is investigated. METHODS A decision-analytic model was developed to estimate the drug costs associated with planned or supplemental prophylaxis and empirical therapy and the costs of treating suspected or documented invasive fungal infections (IFIs) in HCT recipients. Published clinical trial data on 599 patients who received 100-180 days of prophylactic therapy with voriconazole or fluconazole were used to model specified IFI-prevention and mortality outcomes; 6-month, 12-month, and lifetime incremental cost-effectiveness ratios (ICERs) were estimated, with a bootstrap analysis performed to reffect the uncertainty of the clinical trial data. RESULTS Estimated mean total prophylaxis and IFI-related costs associated with voriconazole versus fluconazole prophylaxis over 12 months were higher in the entire study population and among patients receiving HCT for diagnoses other than acute myeloid leukemia (AML) but were not significantly different for patients with AML. The cost per IFI avoided ($66,919) and the cost per life-year gained ($5,453) were lower among patients with AML who received voriconazole relative to the full study population. ICERs were more favorable for voriconazole over a 6-month time frame and when modeling was conducted using generic price data. Assuming a threshold value of $50,000 for one year of life gained, the calculated probability of voriconazole being cost-effective was 33% for the full study population and 85% for the AML subgroup. CONCLUSION The decision model indicated that voriconazole prophylaxis was cost-effective for patients undergoing allogeneic HCT for AML.

Abstract
OBJECTIVES To conduct a retrospective analysis of the association between drug tolerability and potential economic impact measured by medical resource utilization (MRU) for prophylaxis of invasive antifungal infections (IFI) after allogeneic hematopoietic stem cell transplantation (alloHCT). METHODS An open-label, multi-center study (IMPROVIT) included patients (≥12-years old) who were randomized to receive oral voriconazole (VOR) or oral itraconazole (ITR) from the alloHCT day for at least 100 days and up to 180 days. Trial data on discontinuation and MRU for the first 100 days were analyzed. RESULTS Two hundred and twenty-four patients were in VOR and 241 in ITR, with similar demographic distributions (average age of 43 years, 58% male, 92% Caucasian). All-cause and study drug intolerance discontinuations were less frequent with VOR than ITR (50% vs 63%, p = 0.0137; 7% vs 22%, p < 0.0001). VOR patients had longer study drug exposure (median = 96 vs 68 days, p < 0.0001; mean = 68 vs 60 days, p = 0.0044). ITR patients were 2-times more likely (p = 0.0110) to use other antifungals vs VOR patients. Controlling for treatment and key baseline variables, longer IFI prophylaxis was associated with fewer hospital days (p < 0.0001) and less other antifungal use (p < 0.0001). Patients who discontinued prophylaxis during the first 100 days incurred 10 more hospital days (p < 0.0001) and 17 more other antifungal days (p < 0.0001) compared to their counterparts. Eight more prophylaxis days were associated with ∼1 less hospital day and 3.6 less other antifungal days (p < 0.0001). Key limitation: MRU data collection was limited to the first 100 days post-transplant, which may not fully capture the real-world utilization and outcomes. CONCLUSIONS Patients' ability to tolerate and continue their antifungal prophylaxis after alloHCT is associated with less use of MRU such as other antifungals and hospital days. In the current resource-constrained healthcare environment, it is important to consider the potential economic impact of the tolerability of antifungal prophylaxis.

Abstract
PURPOSE To assess the pattern and probable risk factors for moderate and major drug-drug interactions in a referral hematology-oncology ward in Iran. METHODS All patients admitted to hematology-oncology ward of Dr. Shariati Hospital during a 6-month period and received at least two anti-cancer or non-anti-cancer medications simultaneously were included. All being scheduled anti-cancer and non-anti-cancer medications both prescribed and administered during ward stay were considered for drug-drug interaction screening by Lexi-Interact On-Desktop software. RESULTS One hundred and eighty-five drug-drug interactions with moderate or major severity were detected from 83 patients. Most of drug-drug interactions (69.73 %) were classified as pharmacokinetics. Fluconazole (25.95 %) was the most commonly offending medication in drug-drug interactions. Interaction of sulfamethoxazole-trimethoprim with fluconazole was the most common drug-drug interaction (27.27 %). Vincristine with imatinib was the only identified interaction between two anti-cancer agents. The number of administered medications during ward stay was considered as an independent risk factor for developing a drug-drug interaction. CONCLUSIONS Potential moderate or major drug-drug interactions occur frequently in patients with hematological malignancies or related diseases. Performing larger standard studies are required to assess the real clinical and economical effects of drug-drug interactions on patients with hematological and non-hematological malignancies.

Abstract
The incidence of invasive fungal infections (IFIs) has seen a marked increase in the last two decades. This is especially evident among transplant recipients, patients suffering from AIDS, in addition to those in receipt of immunosuppressive therapy. Worryingly, this increased incidence includes infections caused by opportunistic fungi and emerging fungal infections which are resistant to or certainly less susceptible than others to standard antifungal agents. As a direct response to this phenomenon, there has been a resolute effort over the past several decades to improve early and accurate diagnosis and provide reliable screening protocols thereby promoting the administration of appropriate antifungal therapy for fungal infections. Early diagnosis and treatment with antifungal therapy are vital if a patient is to survive an IFI. Substantial advancements have been made with regard to both the diagnosis and subsequent treatment of an IFI. In parallel, stark changes in the epidemiological profile of these IFIs have similarly occurred, often in direct response the type of antifungal agent being administered. The effects of an IFI can be far reaching, ranging from increased morbidity and mortality to increased length hospital stays and economic burden.

Abstract
Many patients suffer from chronic gastrointestinal diseases characterized by chronic inflammation, increased intestinal permeability and visceral pain in which there is no definitive treatment. Adult stem cells have recently been used in various disease states to contribute wound-healing processes. In the current study we investigated the ability of intra-colonic adult stem cells application to heal colonic inflammation in IL-10(-/-) mice with active colitis. The aims of this study were to determine whether intra-colonic infusion of adult colonic stem cells (CSCs) (local stem cell transplantation): (i) restores intestinal permeability; (ii) attenuates visceral hypersensitivity; (iii) heals murine colitis. IL-10(-/-) mice with active colitis were transplanted with adult stem cells. Mice received either a single intracolonic infusion of CSCs or colonic epithelial cells. Two weeks after transplantation, we measured visceral hypersensitivity and intestinal permeability and correlated these with histological improvement of colitis. IL-10(-/-) mice that received stem cell transplantation showed histopathologic evidence of recovery from colitis. Improvement in colitis as graded by pathology scores correlated with restoration of intestinal permeability and decreased visceral hypersensitivity. Intra-colonic administration of CSCs is a potential therapeutic method for treating refractory symptoms in patients with chronic gastrointestinal diseases associated with chronic inflammation and visceral hypersensitivity. This method may be safer and should have far fewer side effects than systemic stem cell administration.
