Abstract
BACKGROUND Aspergillus spp liver abscess is a relatively rare entity and thus far no systematic review has been performed examining patients' demographics, clinical manifestations, diagnosis, management, and outcome. METHODS We performed a systematic review of the literature using MEDLINE and LILACS databases. We searched for articles published in the period from January 1990 to December 24, 2022, to identify patients who developed liver abscesses due to Aspergillus spp. RESULTS Our search yielded 21 patients all of whom had invasive aspergillosis confirmed on liver biopsy. Of these patients 81% were adults, and 60% were males. The majority (86%) of patients were immunocompromised and 95% had symptomatic disease at the time of diagnosis. The most common symptoms were fever (79%), abdominal pain (47%), and constitutional symptoms (weight loss, chills, night sweats, fatigue) (38%). Liver enzymes were elevated in 50%, serum galactomannan was positive in 57%, and fungal blood cultures were positive in only 11%. Co-infection with other pathogens preceded development of apsergillosis in one-third of patients, and the majority of the abscesses (43%) were cryptogenic. In the remaining patients with known source, 28% of patients developed liver abscess through dissemination from the lungs, 19% through the portal vein system, and in 10% liver abscess developed through contiguous spread. The most common imaging modality was abdominal computerized tomography done in 86% of patients. Solitary abscess was present in 52% of patients while 48% had multiple abscesses. Inadequate initial empiric therapy was prescribed in 60% of patients and in 44% of patients definite treatment included combination therapy with two or more antifungal agents. Percutaneous drainage of the abscesses was done in 40% of patients, while 20% required liver resection for the treatment of the abscess. Overall mortality was very high at 38%. CONCLUSION Further studies are urgently needed for a better understanding of pathophysiology of liver aspergillosis and for developement of newer blood markers in order to expedite diagnosis and decrease mortality.

Abstract
BACKGROUND Out of the context of haematological patients, Candida sp. is rarely retrieved from pyogenic liver abscesses (PLA). OBJECTIVES Our objective was to assess the risk factors for occurrence, and clinical, microbiological characteristics, management and outcome of Candida pyogenic liver abscesses (C-PLA). PATIENTS/METHODS We retrospectively analysed C-PLA cases and compared them to pyogenic liver abscesses exclusively due to bacteria (B-PLA) included in our monocentric database on liver abscesses. Unfavourable course was defined as the occurrence of a primary treatment failure (PTF), recurrence after an initial cure, or death within 3 months after diagnosis. RESULTS Between 2010 and 2018, 15 C-PLA and 292 B-PLA were included. All C-PLA had a biliary origin and were polymicrobial. All patients with C-PLA had at least one comorbidity at risk for Candida infection and 7 (53.3%) presented with sepsis requiring an admission in intensive care unit. Median duration of antifungal treatment was 42 days [24-55]. In multivariate analysis, compared with B-PLA, a medical history of malignancy (OR 4.16; 95%CI 1.15-18.72) or liver abscess (OR 7.39; 95%CI 2.10-26.62), and sepsis with severity criteria (OR 3.52; 95%CI 1.07-11.90) were independently associated with the occurrence of C-PLA. In multivariate analysis, C-PLA was associated with a higher risk of recurrence (HR 3.08; 95%CI 1.38-11.22). CONCLUSION Candida liver abscesses in non-neutropenic is a rare and severe disease. The high rate of recurrence should lead to discuss a more intensive treatment.

Can amphotericin B and itraconazole be co-delivered orally? Tailoring oral fixed-dose combination coated granules for systemic mycoses. Eur J Pharm Biopharm 2023; 183:74-91. [PMID: 36623752 DOI: 10.1016/j.ejpb.2023.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 12/06/2022] [Accepted: 01/03/2023] [Indexed: 01/09/2023]
Abstract
The incidence and prevalence of invasive fungal infections have increased significantly over the last few years, leading to a global health problem due to the lack of effective treatments. Amphotericin B (AmB) and itraconazole (ITR) are two antifungal drugs with different mechanisms of action. In this work, AmB and ITR have been formulated within granules to elicit an enhanced pharmacological effect, while enhancing the oral bioavailability of AmB. A Quality by Design (QbD) approach was utilised to prepare fixed-dose combination (FDC) granules consisting of a core containing AmB with functional excipients, such as inulin, microcrystalline cellulose (MCC), chitosan, sodium deoxycholate (NaDC) and Soluplus® and polyvinyl pyrrolidone (PVP), coated with a polymeric layer containing ITR with Soluplus® or a combination of Poloxamer 188 and hydroxypropyl methyl cellulose-acetyl succinate (HPMCAS). A Taguchi design of experiments (DoE) with 7 factors and 2 levels was carried out to understand the key factors impacting on the physicochemical properties of the formulation followed by a Box-Behnken design with 3 factors in 3 levels chosen to optimise the formulation parameters. The core of the FDC granules was obtained by wet granulation and later coated using a fluidized bed. In vitro antifungal efficacy was demonstrated by measuring the inhibition halo against different species of Candida spp., including C. albicans (24.19-30.48 mm), C. parapsilosis (26.38-27.84 mm) and C. krusei (11.48-17.92 mm). AmB release was prolonged from 3 to 24 h when the AmB granules were coated. In vivo in CD-1 male mice studies showed that these granules were more selective towards liver, spleen and lung compared to kidney (up to 5-fold more selective in liver, with an accumulation of 8.07 µg AmB/g liver after twice-daily 5 days administration of granules coated with soluplus-ITR), resulting in an excellent oral administration option in the treatment of invasive mycosis. Nevertheless, some biochemical alterations were found, including a decrease in blood urea nitrogen (∼17 g/dl) and alanine aminotransferase (<30 U/l) and an increase in the levels of bilirubin (∼0.2 mg/dl) and alkaline phosphatase (<80 U/l), which could be indicative of a liver failure. Once-daily regimen for 10 days can be a promising therapy.

Abstract
Light was shield on Fe2+ application as antifungal agent on pitaya postharvest. Fe2+ prevents A. flavus infection by directly binding to A. flavus DNA. This research will promote the research on the mechanism of fungal death. A new strategy was provided to combat fungal infection in fruit postharvest industry.
Aspergillus flavus (A. flavus) is a postharvest fungus, causing pitaya fruit decay and limiting pitaya value and shelf life. However, safer and more efficient methods for preventing A. flavus contamination for pitaya fruit remain to be investigated. In this study, we successfully proved exogenous Fe2+ could inhibit A. flavus colonization in pitaya fruit and extend pitaya’s shelf life after harvest. Moreover, gel electrophoresis, CD analysis and Raman spectrum tests revealed Fe2+ could more effectively and thoroughly promote conidial death by directly binding to A. flavus DNA. Increased expression of DNA damage repair-related genes after Fe2+ treatment was observed by transcription analysis, which might eventually lead to SOS response in A. flavus. These results indicated Fe2+ could prevent A. flavus infestation on pitaya in a novel, quickly responsive mechanism. Our results shed light on the potential application of Fe2+ in the food industry and provided a more universal antifungal agent against food pathogens.

Abstract
Background: Chronic pancreatitis (CP) has been described as a multifactorial, ongoing inflammatory condition of the pancreas of varying intensity that produces persistent pain, leading to exocrine and endocrine insufficiency and a decreased lifespan. Currently, there are three primary forms of chronic pancreatitis: chronic autoimmune pancreatitis (steroid-sensitive pancreatitis), chronic obstructive pancreatitis, and chronic calcific pancreatitis, the latter being closely related to excessive alcohol consumption for one or even two decades before the onset of symptoms. Case report: We present the case of a 29 year old man who required medical attention for a significant unintentional weight loss and a history of upper abdominal pain. Blood tests revealed substantial abnormalities, and the patient was admitted for further investigation. CT and MRI confirmed the presence of a pancreatic pseudocyst and extensive pancreatic parenchymal calcifications and revealed multiple hepatosplenic microabscesses of fungal etiology. Conclusions: Chronic calcifying pancreatitis is a complex clinical entity that can lead to secondary diabetes due to progressive destruction of the pancreatic parenchyma. Protein malnutrition, caused by malabsorption syndrome, immune cell dysfunction, and a high glucose environment caused by diabetes mellitus, may create a state of immunodeficiency, predisposing the patient to opportunistic infections.

Abstract
Hepatic abscesses are a seldom finding although they are the most common type of intraabdominal abscess. We find that this localized collection of pus can be a result of bacteria, ameba, or fungi. This study will mainly focus on the first type, the pyogenic liver abscess (PLA), in which management is predicated on size of abscess. There is no standard definition as to what constitutes a small or large hepatic abscess. Here, we present a case of a 10 cm PLA found in the right lobe of the liver. We aimed to discuss the relevant epidemiology, pathophysiology, clinical manifestations, and management of PLAs.

Abstract
Nutrient uptake is essential for cellular life and the capacity to perceive extracellular nutrients is critical for coordinating their uptake and metabolism. Commensal fungal pathogens, e.g., Candida albicans, have evolved in close association with human hosts and are well-adapted to using diverse nutrients found in discrete host niches. Human cells that cannot synthesize all amino acids require the uptake of the “essential amino acids” to remain viable. Consistently, high levels of amino acids circulate in the blood. Host proteins are rich sources of amino acids but their use depends on proteases to cleave them into smaller peptides and free amino acids. C. albicans responds to extracellular amino acids by pleiotropically enhancing their uptake and derive energy from their catabolism to power opportunistic virulent growth. Studies using Saccharomyces cerevisiae have established paradigms to understand metabolic processes in C. albicans; however, fundamental differences exist. The advent of CRISPR/Cas9-based methods facilitate genetic analysis in C. albicans, and state-of-the-art molecular biological techniques are being applied to directly examine growth requirements in vivo and in situ in infected hosts. The combination of divergent approaches can illuminate the biological roles of individual cellular components. Here we discuss recent findings regarding nutrient sensing with a focus on amino acid uptake and metabolism, processes that underlie the virulence of C. albicans.

Abstract
Fungal respiratory tract colonisation is a common finding in patients with hematologic neoplasms due to immunosuppression inherent in the diseases and exacerbated by therapy. This greatly increases the risk of fungal infections of the lungs, which is associated with significant mortality. Therefore, reliable diagnostic methods with rapidly available results are needed to administer adequate antifungal therapy.We have established an improved method for fungal DNA extraction and amplification that allows simultaneous detection of fungal families based on a set of multiplexed real time PCR reactions (fuPCR). We analysed respiratory rinses and blood of 94 patients with haematological systemic diseases by fuPCR and compared it with the results of culture and serological diagnostic methods. 40 healthy subjects served as controls.Regarding Candida species, the highest prevalence resulted from microbiological culture of respiratory rinses and from detection of antibodies in blood serum in patients (61% and 47%, respectively) and in the control group (29% and 51%, respectively). Detection of other pathogenic yeasts, such as Cryptococcus and Trichosporon, and moulds, such as Fusarium, was only possible in patients by fuPCR from both respiratory rinses and whole blood and serum. These fungal species were found statistically significantly more frequent in respiratory rinses collected from patients after myeloablative therapy for stem cell transplantation compared to samples collected before treatment (p<<0.05i>).The results show that fuPCR is a valuable complement to culturing and its inclusion in routine mycological diagnostics might be helpful for early detection of pathophysiologically relevant respiratory colonisation for patients with hematologic neoplasms. LAY ABSTRACT We validated a set of PCR reactions (fuPCR) for use in routine diagnostic. In contrast to culture and serological methods, only by fuPCR pathogenic yeasts (Cryptococcus and Trichosporon) and moulds (Aspergillus and Fusarium) were detected in respiratory rinses and blood of haematological patients.

Abstract
Hepatic candidiasis is a manifestation of disseminated candidiasis, which typically presents in immunocompromised patients. Focal hepatic candidiasis in immunocompetent patients, however, is infrequent/extremely rare. We present the case of an immunocompetent female patient who presented with respiratory distress and right-sided pleural effusion. The pleural fluid tap did not grow anything, and a contrast-enhanced computed tomography (CT) scan revealed a right liver lobe subcapsular collection. CT-guided aspiration and culture resulted in Candida albicans growth. The patient responded to oral fluconazole, and a follow-up CT scan demonstrated resolution of the collection. Although hepatic candidiasis rarely occurs in immunocompetent patients, it should be included in the differential diagnosis of hepatic abscesses, as timely diagnosis and management are crucial in conferring a good prognosis.

Abstract
Intra-abdominal infection (peritonitis) is a leading cause of severe disease in surgical intensive care units, as over 70% of patients diagnosed with peritonitis develop septic shock. A critical role of the immune system is to return to homeostasis after combating infection. S100A8/A9 (calprotectin) is an antimicrobial and pro-inflammatory protein complex used as a biomarker for diagnosis of numerous inflammatory disorders. Here we describe the role of S100A8/A9 in inflammatory collateral tissue damage (ICTD). Using a mouse model of disseminated intra-abdominal candidiasis (IAC) in wild-type and S100A8/A9-deficient mice in the presence or absence of S100A9 inhibitor paquinimod, the role of S100A8/A9 during ICTD and fungal clearance were investigated. S100A8/A9-deficient mice developed less ICTD than wild-type mice. Restoration of S100A8/A9 in knockout mice by injection of recombinant protein resulted in increased ICTD and fungal clearance comparable to wild-type levels. Treatment with paquinimod abolished ICTD and S100A9-deficient mice showed increased survival compared to wild-type littermates. The data indicates that S100A8/A9 controls ICTD levels and antimicrobial activity during IAC and that targeting of S100A8/A9 could serve as promising adjunct therapy against this challenging disease.

Abstract
BACKGROUND Liver abscesses caused by Candida species are mainly found in immunocompromised hosts, associated with conditions (such as neutropenia and mucositis) that facilitate the spreading of microorganisms from the gastrointestinal tract. CASE REPORT We present the case of a non-immunocompromised 72-year-old woman with a liver abscess caused by Candida haemulonii var. vulnera, in whom potential associated conditions could be polycystic kidney disease and renal replacement therapy. The patient experienced clinical resolution after percutaneous drainage and treatment with caspofungin. CONCLUSIONS To our knowledge, this is the first case reported in Peru of a liver abscess due to Candida haemulonii var. vulnera, a clinical presentation that has not been described previously. This finding should prompt us to establish active surveillance of causal agents of systemic candidiasis.

Hepatic dysfunction impairs prognosis in critically ill patients with hematological malignancies: A post-hoc analysis of a prospective multicenter multinational dataset. J Crit Care 2020; 62:88-93.

Abstract
PURPOSE Hyperbilirubinemia is frequent in patients with hematological malignancies admitted to the intensive care unit (ICU). Literature about hepatic dysfunction (HD) in this context is scarce. METHODS We investigated the prognostic impact of HD analyzing a prospective multicenter cohort of 893 critically ill hematology patients. Two groups were defined: patients with HD (total bilirubin ≥33 μmol/L at ICU admission) and patients without HD. RESULTS Twenty one percent of patients were found to have HD at ICU admission. Cyclosporine, antimicrobials before ICU admission, abdominal symptoms, ascites, history of liver disease, neutropenia, increased serum creatinine and myeloma were independently associated with HD. Etiology remained undetermined in 73% of patients. Hospital mortality was 56.3% and 36.3% respectively in patients with and without HD (p < 0.0001). Prognostic factors independently associated with hospital mortality in HD group were, performance status >1 (OR = 2.07, 95% CI = 1.49-2.87, p < 0.0001), invasive mechanical ventilation (OR = 3.92, 95% CI = 2.69-5.71, p < 0.0001), renal replacement therapy (OR = 1.74, 95% CI = 1.22-2.47, p = 0.002), vasoactive drug (OR = 1.81, 95% CI = 1.21-2.71, p = 0.004) and SOFA score without bilirubin level at ICU admission (OR = 1.09, 95% CI = 1.04-1.14, p < 0.0001). CONCLUSIONS HD is common, underestimated, infrequently investigated, and is associated with impaired outcome in critically ill hematology patients. HD should be considered upon ICU admission and managed as other organ dysfunctions.

Aspergillus fumigatus population dynamics and sensitivity to demethylation inhibitor fungicides in whole-crop corn, high moisture corn and wet grain corn silages. PEST MANAGEMENT SCIENCE 2020; 76:685-694. [PMID: 31347787 DOI: 10.1002/ps.5566] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 07/22/2019] [Accepted: 07/22/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Aspergillus fumigatus, the causal agent of aspergillosis in humans, is commonly present as a saprophyte in various organic substrates, such as spoiled silages. Aspergillosis is generally combated with demethylation inhibitor (DMI) fungicides, but the recent appearance of resistant medical and environmental strains made current treatment strategies less reliable. The goal of this study was to determine the evolution of A. fumigatus populations during the ensiling process of whole-crop corn, high moisture corn and wet grain corn, and to monitor the sensitivity of isolates from treated and untreated fields to one medical and one agricultural DMI fungicide. RESULTS A. fumigatus was isolated from fresh forage at harvest at rather low concentrations (102 cfu g-1 ). The low frequency lingered during the silage process (at 60 and 160 days), whereas it significantly increased during air exposure (at 7 and 14 days of air exposure). Field treatment of corn with a mixture of prothioconazole and tebuconazole did not affect the sensitivity of A. fumigatus isolates. One of 29 isolates from the untreated plot was resistant to voriconazole. A unique amino acid substitution (E427K) was detected in the cyp51A gene of 10 of 12 sequenced isolates, but was not associated with DMI resistance. CONCLUSION A. fumigatus significantly increased during aerobic deterioration of ensilaged corn after silo opening, compared with the low presence in fresh corn and during ensiling. Field treatment of corn with DMI fungicides did not affect the sensitivity of A. fumigatus isolates collected from fresh and ensiled corn. © 2019 Society of Chemical Industry.

Abstract
Liver disease in children occurs via a multitude of primary illnesses such as autoimmune hepatopathy, biliary atresia, and nonalcoholic fatty liver disease. However, jaundice, hepatitis, and alterations in liver tests can often be a manifestation of systemic diseases. The liver is involved in many critical functions such as circulation, immunity, toxin clearance, and metabolism; when the heart, lungs, gastrointestinal tract, immune system, or endocrine systems are compromised, the liver will be affected. This article reviews common causes of liver injury as well as highlights key associations that should not be missed when diagnosing and managing children with liver disease. Becoming familiar with patterns of liver injury and arranging clues in the context of a thorough history and physical examination can help providers navigate the broad differential diagnosis of secondary liver disease. [Pediatr Ann. 2018;47(11):e458-e464.].
