Abstract
Background Perforated peptic ulcer disease has a high mortality rate, and there is consensus regarding the use of antifungals in the management of immunocompromised patients; however, there is variability in the utilization of antifungals in the non-immunocompromised cohort. This study aims to describe the current practice related to the use of antifungals in perforated peptic ulcer disease in Western Australia and to determine the peri-operative morbidity and mortality in the immunocompromised and non-immunocompromised cohort receiving antifungals. Methods Medical records of patients who underwent surgical repair of perforated peptic ulcer in all Western Australian tertiary hospitals between January 1, 2010, and December 31, 2017, were reviewed retrospectively. Data regarding pre-operative patient factors such as age, gender, and comorbidities, post-operative outcomes such as intra-abdominal sepsis/bleeding, peri-operative antifungal prescription, and abundance of fungal growth on intra-operative samples were collected. Results The study included 359 patients. The antifungal prescription was variable. An American Society of Anesthesiologists (ASA) score of 3 or more, presence of pre-operative shock and acidosis, and level of abundance of fungal growth on intra-operative samples were associated with antifungal prescription. Amongst the non-immunocompromised cohort, receiving antifungals was associated with higher morbidity. Conclusion The use of antifungals for patients with perforated peptic ulcer disease was variable. An ASA score of 3 or greater and pre-operative shock and acidosis are pre-operative factors predisposing patients to receiving antifungals. There was no difference in morbidity or mortality amongst immunocompromised patients regardless of antifungal prescription or non-prescription. However, in the non-immunocompromised cohort, those who received antifungals had a higher morbidity compared to those who did not.

Farnesol remodels the peritoneal cavity immune environment influencing Candida albicans pathogenesis during intra-abdominal infection. Infect Immun 2023; 91:e0038423.

Abstract
Candida albicans is a lifelong member of the mycobiome causing mucosal candidiasis and life-threatening, systemic, and intra-abdominal disease in immunocompromised and transplant patients. Despite the clinical importance of intra-abdominal candidiasis with mortality rates between 40% and 70%, the contribution of fungal virulence factors and host immune responses to disease has not been extensively studied. Secretion of the quorum-sensing molecule, farnesol, acts as a virulence factor for C. albicans during systemic infection, while inducing local, protective innate immune responses in oral models of infection. Previously, we reported that farnesol recruits macrophages to the peritoneal cavity in mice, suggesting a role for farnesol in innate immune responses. Here, we expand on our initial findings, showing that farnesol profoundly alters the peritoneal cavity microenvironment promoting innate inflammation. Intra-peritoneal injection of farnesol stimulates rapid local death of resident peritoneal cells followed by recruitment of neutrophils and inflammatory macrophages into the peritoneal cavity and peritoneal mesothelium associated with an early increase in chemokines followed by proinflammatory cytokines. These rapid inflammatory responses to farnesol significantly increase morbidity and mortality of mice with intra-abdominal candidiasis associated with increased formation of peritoneal adhesions, despite similar rates of fungal clearance from the peritoneal cavity and retro-peritoneal organs. C. albicans ddp3Δ/ddp3Δ knockout and reconstituted strains recapitulate these findings. This indicates that farnesol may be detrimental to the host during intra-abdominal infections. Importantly, our results highlight a need to understand how C. albicans virulence factors modulate the host immune response within the peritoneum, an exceedingly common site of Candida infection.

Antibiotics (Basel) 2023; 12:antibiotics12040701. [PMID: 37107063 PMCID: PMC10135368 DOI: 10.3390/antibiotics12040701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/16/2023] [Accepted: 03/22/2023] [Indexed: 04/07/2023] Open
Abstract
The role of empiric antifungals for post-surgical abscesses (PSAs) is controversial, and international guidelines on invasive mycoses focus on bloodstream infections. We analyzed a retrospective cohort of 319 patients with PSA at a tertiary-level hospital in Italy during the years 2013–2018. Factors associated with empiric antifungal administration were analyzed and compared with factors associated with fungal isolation from the abdomen. Forty-six patients (14.4%) received empiric antifungals (65.2% azoles). Candida was isolated in 34/319 (10.7%) cases, always with bacteria. Only 11/46 patients receiving empirical antifungals had abdominal Candida. Only 11/34 patients with a fungal isolate received empiric antifungal therapy. Upper GI surgery (OR: 4.76 (CI: 1.95–11.65), p = 0.001), an intensive care unit stay in the previous 90 days (OR: 5.01 (CI: 1.63–15.33), p = 0.005), and reintervention within 30 days (OR: 2.52 (CI: 1.24–5.13), p = 0.011) were associated with empiric antifungals in a multivariate analysis, while pancreas/biliary tract surgery was associated with fungal isolation (OR: 2.25 (CI: 1.03–4.91), p = 0.042), and lower GI surgery was protective (OR: 0.30 (CI: 0.10–0.89), p = 0.029) in a univariate analysis. The criteria for empiric antifungal therapy in our practice seem to be inconsistent with the risk factors for actual fungal isolation. Better guidance for empiric therapy should be provided by wider studies.

Invasive Fungal Breakthrough Infections under Targeted Echinocandin Prophylaxis in High-Risk Liver Transplant Recipients. J Fungi (Basel) 2023; 9:jof9020272. [PMID: 36836384 PMCID: PMC9961099 DOI: 10.3390/jof9020272] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 02/15/2023] [Accepted: 02/17/2023] [Indexed: 02/22/2023] Open
Abstract
Invasive fungal infections (IFIs) are frequent and outcome-relevant complications in the early postoperative period after orthotopic liver transplantation (OLT). Recent guidelines recommend targeted antimycotic prophylaxis (TAP) for high-risk liver transplant recipients (HR-LTRs). However, the choice of antimycotic agent is still a subject of discussion. Echinocandins are increasingly being used due to their advantageous safety profile and the increasing number of non-albicans Candida infections. However, the evidence justifying their use remains rather sparse. Recently published data on breakthrough IFI (b-IFI) raise concerns about echinocandin efficacy, especially in the case of intra-abdominal candidiasis (IAC), which is the most common infection site after OLT. In this retrospective study, we analyzed 100 adult HR-LTRs undergoing first-time OLT and receiving echinocandin prophylaxis between 2017 and 2020 in a tertiary university hospital. We found a breakthrough incidence of 16%, having a significant impact on postoperative complications, graft survival, and mortality. The reasons for this may be multifactorial. Among the pathogen-related factors, we identified the breakthrough of Candida parapsilosis in 11% of patients and one case of persistent IFI due to the development of a secondary echinocandin resistance of an IAC caused by Candida glabrata. Consequently, the efficacy of echinocandin prophylaxis in liver transplantation should be questioned. Further studies are necessary to clarify the matter of breakthrough infections under echinocandin prophylaxis.

Incidence of Invasive Fungal Infections in Liver Transplant Recipients under Targeted Echinocandin Prophylaxis. J Clin Med 2023; 12:jcm12041520.

Abstract
Invasive fungal infections (IFIs) are one of the most important infectious complications after liver transplantation, determining morbidity and mortality. Antimycotic prophylaxis may impede IFI, but a consensus on indication, agent, or duration is still missing. Therefore, this study aimed to investigate the incidence of IFIs under targeted echinocandin antimycotic prophylaxis in adult high-risk liver transplant recipients. We retrospectively reviewed all patients undergoing a deceased donor liver transplantation at the Medical University of Innsbruck in the period from 2017 to 2020. Of 299 patients, 224 met the inclusion criteria. We defined patients as being at high risk for IFI if they had two or more prespecified risk factors and these patients received prophylaxis. In total, 85% (190/224) of the patients were correctly classified according to the developed algorithm, being able to predict an IFI with a sensitivity of 89%. Although 83% (90/109) so defined high-risk recipients received echinocandin prophylaxis, 21% (23/109) still developed an IFI. The multivariate analysis identified the age of the recipient (hazard ratio-HR = 0.97, p = 0.027), split liver transplantation (HR = 5.18, p = 0.014), massive intraoperative blood transfusion (HR = 24.08, p = 0.004), donor-derived infection (HR = 9.70, p < 0.001), and relaparotomy (HR = 4.62, p = 0.003) as variables with increased hazard ratios for an IFI within 90 days. The fungal colonization at baseline, high-urgency transplantation, posttransplant dialysis, bile leak, and early transplantation showed significance only in a univariate model. Notably, 57% (12/21) of the invasive Candida infections were caused by a non-albicans species, entailing a markedly reduced one-year survival. The attributable 90-day mortality rate of an IFI after a liver transplant was 53% (9/17). None of the patients with invasive aspergillosis survived. Despite targeted echinocandin prophylaxis, there is still a notable risk for IFI. Consequently, the prophylactic use of echinocandins must be critically questioned regarding the high rate of breakthrough infections, the increased occurrence of fluconazole-resistant pathogens, and the higher mortality rate in non-albicans Candida species. Adherence to the internal prophylaxis algorithms is of immense importance, bearing in mind the high IFI rates in case algorithms are not followed.

Abstract
Candida, as a part of the human microbiota, can cause opportunistic infections that are either localised or systemic candidiasis. Emerging resistance to the standard antifungal drugs is associated with increased mortality rate due to invasive Candida infections, particularly in immunocompromised patients. While there are several species of Candida, an increasing number of Candida tropicalis isolates have been recently reported from patients with invasive candidiasis or inflammatory bowel diseases. In order to establish infections, C. tropicalis has to adopt several strategies to escape the host immune attack. Understanding the immune evasion strategies is of great importance as these can be exploited as novel therapeutic targets. C. albicans pH-related antigen 1 (CaPra1), a surface bound and secretory protein, has been found to interact strongly with the immune system and help in complement evasion. However, the role of C. tropicalis Pra1 (CtPra1) and its interaction with the complement is not studied yet. Thus, we characterised how pH-related antigen 1 of C. tropicalis (CtPra1) interacts with some of the key complement proteins of the innate immune system. CtPra1 was recombinantly produced using a Kluyveromyces lactis yeast expression system. Recombinant CtPra1, was found to bind human C3 and C3b, central molecules of the complement pathways that are important components of the innate immune system. It was also found to bind human complement regulatory proteins factor-H and C4b-binding protein (C4BP). CtPra1-factor-H and CtPra1-C4BP interactions were found to be ionic in nature as the binding intensity affected by high sodium chloride concentrations. CtPra1 inhibited functional complement activation with different effects on classical (∼20 %), lectin (∼25 %) and alternative (∼30 %) pathways. qPCR experiments using C. tropicalis clinical isolates (oral, blood and peritoneal fluid) revealed relatively higher levels of expression of CtPra1 gene when compared to the reference strain. Native CtPra1 was found to be expressed both as membrane-bound and secretory forms in the clinical isolates. Thus, C. tropicalis appears to be a master of immune evasion by using Pra1 protein. Further investigation using in-vivo models will help ascertain if these proteins can be novel therapeutic targets.

Abstract
Candidal infection of the gastrointestinal tract (GIT) is rare but has recently increased due to the increased number of immunocompromised patients, injudicious use of antibacterial agents, and prolonged use of antacid drugs in immunocompetent patients. The most frequent organ involved in GIT candidiasis is the esophagus, followed by the stomach, small intestine, and large intestine. The clinical spectrum of gastric candidiasis ranges from asymptomatic to gastric perforation and even shock. This case report presents a 58-year-old immunocompetent male patient diagnosed with Candida tropicalis-induced gastric perforation peritonitis.

Abstract
Invasive candidiasis (IC) has emerged in the last decades as an important cause of morbidity, mortality, and economic load in the intensive care unit (ICU). The epidemiology of IC is still a difficult and unsolved enigma for the literature. Accurate estimation of the true burden of IC is difficult due to variation in definitions and limitations inherent to available case-finding methodologies. Candidemia and intra-abdominal candidiasis (IAC) are the two predominant types of IC in ICU. During the last two decades, an increase in the incidence of candidemia has been constantly reported particularly in the expanding populations of elderly or immunosuppressed patents, with a parallel change in Candida species (spp.) distribution worldwide. Epidemiological shift in non-albicans spp. has reached worrisome trends. Recently, a novel, multidrug-resistant Candida spp., Candida auris, has globally emerged as a nosocomial pathogen causing a broad range of healthcare-associated invasive infections. Epidemiological profile of IAC remains imprecise. Though antifungal drugs are available for Candida infections, mortality rates continue to be high, estimated to be up to 50%. Increased use of fluconazole and echinocandins has been associated with the emergence of resistance to these drugs, which affects particularly C. albicans and C. glabrata. Crucial priorities for clinicians are to recognize the epidemiological trends of IC as well as the emergence of resistance to antifungal agents to improve diagnostic techniques and strategies, develop international surveillance networks and antifungal stewardship programmes for a better epidemiological control of IC.

Abstract
Background: The delayed diagnosis of the presence of Candida in severe intra-abdominal infections exposes patients to an increased risk of mortality. The prevalence of intra-abdominal candidiasis (IAC) varies with the type of intra-abdominal infection, the underlying conditions and the presence of risk factors for Candida infection. This study aims to evaluate the interest of the measure of 1.3-β-D-glucan (BDG) in the peritoneal fluid for the early diagnosis of IAC. Methods and analysis: This is a prospective multicenter (n = 5) non-interventional study, focusing on all critically ill patients with an intra-abdominal infection requiring intra-abdominal surgery. The primary objective is to assess the diagnostic performance of the BDG measured in the peritoneal fluid for the early detection of IAC using the Candida culture as the gold standard. The secondary objective is to report the prevalence of IAC in the selected population. This study aims to enroll 200 patients within 48 months. By estimating the prevalence of IAC in the selected population at 30%, 50 patients with IAC (cases) are expected. These 50 IAC cases will be matched with 50 non-IAC patients (as a control group). The peritoneal BDG will be measured a posteriori in all of these 100 selected patients. This article presents the protocol and the current status of the study. Only the prevalence of IAC is reported as preliminary result.

Abstract
Invasive candidiasis is a common healthcare-associated infection with high mortality and is difficult to diagnose due to nonspecific symptoms and limitations of culture based diagnostic methods. T2Candida, based on T2 magnetic resonance technology, is FDA approved for the diagnosis of candidemia and can rapidly detect the five most commonly isolated Candida sp. in approximately 5 h directly from whole blood. We discuss the preclinical and clinical studies of T2Candida for the diagnosis of candidemia and review the current literature on its use in deep-seated candidiasis, its role in patient management and prognosis, clinical utility in unique populations and non-blood specimens, and as an antifungal stewardship tool. Lastly, we summarize the strengths and limitations of this promising nonculture-based diagnostic test.

Abstract
Abstract
The gastrointestinal tract perforation is one of the leading causes of acute abdomen. Mycotic infections have become a significant clinical problem over the last few decades. Despite the advance in diagnostics and treatment of patients with fungal peritonitis, the mortality remains high.
Objective. The objective of the study was to determine the type and incidence of causative pathogens of acute peritonitis in patients with gastroduodenal perforation, and to estimate the impact of microbial flora on the disease outcome.
Materials and methods. We performed a retrospective study among 83 adult patients with acute peritonitis due to gastroduodenal perforation treated at our centre.
Results. A total of 40 mycotic agents were isolated in 39 of the abdominal samples. The primary mycotic isolates were Candida albicans (52.5%) and C. glabrata (64.3%); C. krusei (14.3%) and C. tropicalis (7.1%) predominated among non-albicans Candida species (35.0%). The most common bacterial agents were Escherichia coli (24.0%) and Enterococcus spp. (24.0%). 77.1% of all enrolled patients survived, and 19 of them deceased due to sepsis and multiple organ dysfunction syndrome.
Conclusion. Candida albicans is the most common mycotic pathogen in patients with acute peritonitis due to gastroduodenal perforation. It is obligatory to examine the peritoneal fluid samples for bacterial and fungal pathogens with determination of their antimicrobial susceptibility profile. Timely initiation of adequate treatment and multidisciplinary approach is crucial for the outcome of patients with fungal peritonitis.

Abstract
INTRODUCTION Peritonitis is still an important health problem associated with high morbidity and mortality. A multidisciplinary approach to the management of patients with peritonitis may be an important factor to reduce the risks for patients and improve efficiency, outcome, and the cost of care. METHODS Expert panel discussion on Peritonitis was held in Bucharest on May 2017, during the 17th ECTES Congress, involving surgeons, infectious disease specialists, radiologists and intensivists with the goal of defining recommendations for the optimal management of peritonitis. CONCLUSION This document is an updated presentation of management of peritonitis and represents the summary of the final recommendations approved by a panel of experts.

Abstract
Background Peptic ulcer disease is common with a lifetime prevalence in the general population of 5-10% and an incidence of 0.1-0.3% per year. Despite a sharp reduction in incidence and rates of hospital admission and mortality over the past 30 years, complications are still encountered in 10-20% of these patients. Peptic ulcer disease remains a significant healthcare problem, which can consume considerable financial resources. Management may involve various subspecialties including surgeons, gastroenterologists, and radiologists. Successful management of patients with complicated peptic ulcer (CPU) involves prompt recognition, resuscitation when required, appropriate antibiotic therapy, and timely surgical/radiological treatment. Methods The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the board of the WSES to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the 5th WSES Congress, and for each statement, a consensus among the WSES panel of experts was reached. Conclusions The population considered in these guidelines is adult patients with suspected complicated peptic ulcer disease. These guidelines present evidence-based international consensus statements on the management of complicated peptic ulcer from a collaboration of a panel of experts and are intended to improve the knowledge and the awareness of physicians around the world on this specific topic. We divided our work into the two main topics, bleeding and perforated peptic ulcer, and structured it into six main topics that cover the entire management process of patients with complicated peptic ulcer, from diagnosis at ED arrival to post-discharge antimicrobial therapy, to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

Abstract
Background: Fungal isolates from peritoneal fluid sampling in patients with perforated peptic ulcer (PPU) is not uncommon and its management unclear. This study aims to evaluate whether the presence of fungus in peritoneal fluid cultures is a predictor of morbidity and mortality after laparotomy for PPU. Method: This is a single-center retrospective study including adult patients with perforated gastric and duodenal ulcers over a 10-year period (January 2004 to January 2014). Evaluation of predictors contributing to fungal growth was conducted using multiple logistic regression analysis. Operative factors and 30-day mortality and morbidity outcomes were compared against fungal growth using a multivariable generalized linear mixed model analysis. Results: The median age was 58 (interquartile range [IQR] 44-70) years with 110 (20.3%) females. In addition to hypertension and hyperlipidemia, diabetes mellitus (13.5%), ischemic heart disease (2.6%), and heart failure (2.4%) were common. Fungus was cultured from peritoneal fluid in 209 (38.6%) patients. Median American Society of Anesthesiology (ASA) score was 2 (IQR 2-3) and median Mannheim peritonitis index (MPI) score was 15 (IQR 10-20). Free air was detected in 323 (59.6%) patients and 52 (9.6%) patients had gastrectomy. Median length of stay was 7 (IQR 6-11) days. All-cause complications were seen in 53 (9.8%) patients, of whom 37 patients (6.8%) developed intra-abdominal collection, 20 patients (3.7%) had anastomotic leakage, and 12 patients (2.2%) required repeat operation. Thirty-day mortality was seen in 47 (8.7%) patients. Multivariable analysis showed age (median age, 64; IQR 53-74) as a predictor of fungal growth (p < 0.001) but fungal growth not a predictor of adverse peri-operative outcomes. Conclusion: Fungal isolates in peritoneal fluid cultures are more likely to occur in older patients who have PPU. Presence of fungal isolates does not impact peri-operative outcomes.

Abstract
BACKGROUND There currently exists no substantial evidence reporting the efficacy of peritoneal irrigation in reducing the incidence of postoperative intra-abdominal abscess in pediatric patients. The purpose of our study was to perform a meta-analysis to compare rates of intra-abdominal abscess after appendectomy between irrigation and suction alone groups. METHODS We identified studies by a systematic search in EMBASE, PubMed, Web of Science, and the Cochrane Library to recognize randomized controlled trials and case control studies from the 1950 to May 2019. We limited the English language studies. We checked the reference list of studies to recognize other potentially qualified trials. We analyzed the merged data with use of the Review Manager 5.3. RESULTS We identified 6 eligible papers enrolling a total of 1633 participants. We found no significant difference in the incidence of postoperative intraabdominal abscess, wound infection, and the length of hospitalization between 2 group, but duration of surgery is longer in irrigation group (MD = 6.76, 95% CI = 4.64 to 8.87, P < .001; heterogeneity, I = 25%, P = .26). CONCLUSION Our meta-analysis did not provide strong evidence allowing definite conclusions to be drawn, but suggested that peritoneal irrigation during appendectomy did not decrease the incidence of postoperative IAA. This meta-analysis also indicated the need for more high-quality trials to identify methods to decrease the incidence of postoperative IAA in pediatric perforated appendicitis patients.Trial registration number Standardization of endoscopic treatment of acute abdomen in children: 14RCGFSY00150.

Abstract
PURPOSE Peritonitis is a major complication of bariatric surgery due to direct damage to the natural barriers to infection. Most such secondary peritoneal infections are caused by Gram-negative microorganisms; however, under certain conditions, Candida species can infect the peritoneal cavity following bariatric surgery. MATERIALS AND METHODS We retrospectively analyzed the clinical and microbiological data of morbidly obese patients who suffered infectious complications following laparoscopic sleeve gastrectomy (LSG) at the Soroka Medical Center between January 2010 and June 2015. RESULTS Out of 800 patients who underwent LSG, 43 (5.3%( developed secondary peritonitis and were admitted to our General Intensive Care Unit during the study period. Intraperitoneal leaks, intraabdominal abscesses and pleural effusions were significantly more common in patients with fungal infection than in those with non-fungal infections (p values 0.027, < 0.001, and < 0.014, respectively). Leaks situated at the suture line of gastro-esophageal area occurred much more frequently in the fungal infection group than in the non-fungal infection group (94.7 vs 41.7%, p < 0.001). Microbiological analysis of the abdominal and pleural fluids of patients with invasive fungal infectious complications showed the presence of commensal polymicrobial bacterial infections-mainly Streptoccocus constellatus and coagulase negative Staphylococcus spp. Leakage at the suture line of gastro-esophageal area (upper suture part) and administration of parenteral nutrition were found to be independent predictors for invasive fungal infections after LSG. CONCLUSION Our study demonstrates that invasive fungal infection is a significant postoperative infectious complication of bariatric LSG surgery in morbidly obese patients.

Abstract
A robust, sensitive, and time-competitive system to detect Candida albicans in less than 30 min in clinical samples based in capped nanoporous anodic alumina (NAA) is developed. In the proposed design, NAA pores are loaded with rhodamine B and then blocked with an oligonucleotide that is able to recognize C. albicans DNA. The capped material shows negligible cargo release, whereas dye delivery is selectively accomplished when genomic DNA from C. albicans is present. This procedure has been successfully applied to detect C. albicans in clinical samples from patients infected with this yeast. When compared with classical C. albicans detection methods, the proposed probe has a short assay time, high sensitivity and selectivity, demonstrating the high potential of this simple design for the diagnosis of infection produced by C. albicans.

Abstract
High ascitic amylase concentration has been reported to be a characteristic of pancreatic ascites. However, values greater than 2000 U/l can also be seen in intestinal perforation. Fungal peritonitis is a serious entity that could also be caused by hollow viscous perforation. Herein we report a 22-year-old woman with epigastric pain, imitating an acute pancreatitis, and abdominal distention. Laboratory and radiological investigations revealed a high ascitic Amylase level with secondary fungal peritonitis due to gastric ulcer perforation. This case highlights the importance of careful clinical evaluation and a multi-disciplines approach in patients with high ascitic Amylase levels especially in limited-resources areas in order not to miss a diagnosis in which a surgical approach can be lifesaving. To the best of our knowledge, this is the first reported case of concomitant very high ascetic Amylase level and fungal peritonitis as a manifestation of gastric perforation.

Abstract
Despite advances in antifungal therapy, invasive fungal infections remain a significant cause of morbidity and mortality worldwide. One important factor contributing to the relative ineffectiveness of existing antifungal drugs is insufficient drug exposure at the site of infection. Despite the importance of this aspect of antifungal therapy, we generally lack a full appreciation of how antifungal drugs distribute, penetrate, and interact with their target organisms in different tissue subcompartments. A better understanding of drug distribution will be critical to guide appropriate use of currently available antifungal drugs, as well as to aid development of new agents. Herein we briefly review current perspectives of antifungal drug exposure at the site of infection and describe a new technique, matrix-assisted laser desorption ionization (MALDI) mass spectrometry imaging, which has the potential to greatly expand our understanding of drug penetration.

Abstract
BACKGROUND Decision to start an anti-fungal therapy in intra-abdominal candidiasis (IAC) is complex. Yeast culture, considered the gold standard, suffers from a delayed response time and exposes the patient to delayed introduction of anti-fungal therapy. We sought to evaluate the performance and feasibility of measuring 1,3-β-D-glucan (1,3-BDG) in the peritoneal fluid (PF) for the diagnosis of IAC. METHODS We analyzed retrospectively all PF obtained during abdominal surgery for critically ill adult patients presenting intra-abdominal infections. For each PF sample, direct examination, bacterial and fungal culture, fungal PCR and 1,3-BDG measurements were performed. The diagnostic performance of each technique and the Peritonitis score were calculated considering the positive yeast culture as the reference. The levels of 1,3-BDG were compared between IAC and non-IAC patients. RESULTS During an 8-month period in 2016, 33 PF samples were recovered. Median (interquartile range) SAPS 2 and SOFA scores were 44 (9-94) and 9 (4-15), respectively. There were seven cases of IAC, 14 of bacterial peritonitis and 12 of undocumented peritonitis. All IAC cases were secondary peritonitis, with a 1,3-BDG level of 1461 (325-5000) versus 224 (68-1357) pg/mL in the non-IAC group (P=0.03). When the 1,3-BDG level was ≤310 pg/mL, its negative predictive value was 100%. CONCLUSIONS In secondary peritonitis, a peritoneal measurement of 1,3-BDG ≤310 pg/mL could rule out IAC.

Abstract
The mortality associated with invasive candidiasis remains unacceptably high. The T2 magnetic resonance (T2MR) assay is a novel US FDA-approved molecular diagnostic assay for the diagnosis of candidemia that can rapidly detect the five most commonly isolated Candida spp. In clinical trials, T2MR has exhibited good clinical sensitivity and specificity. Potential benefits from the adoption of T2MR technology in the diagnostic and therapeutic algorithms for invasive candidiasis can arise from timely diagnosis of disease, increased case detection, tailored therapy and decrease in empiric antifungal treatment. As everyday clinical experience with the assay is evolving, we discuss the utility of T2MR in invasive candidiasis with and without candidemia based on the currently available evidence regarding its performance.

Abstract
Upper gastrointestinal tract (GIT) surgical procedures are more likely to cause nosocomial Candida peritonitis than lower GIT procedures and they thus constitute an independent risk factor for mortality. Because of the severity of postsurgical fungal infections complications, intensivists and surgeons need to be extremely aware of their clinical importance in critically ill postsurgical intensive care unit (ICU) patients. We analyzed the clinical and microbiological data of 149 oncologic patients who were hospitalized in the ICU at Soroka Medical Center between January 2010 and January 2015 after undergoing upper GIT surgery for gastric cancer. Invasive fungal infections related to secondary peritonitis following oncologic upper GIT surgery had a higher mortality rate than patients with nonfungal postoperative infectious complications. The presence of gastroesophageal junction leakage and advanced age were found to be independent risk factors for invasive fungal infection after oncologic upper GIT surgery.

Abstract
Intra-abdominal candidiasis (IAC) is a prominent invasive fungal infection associated with high mortality. Prompt antifungal therapy and source control are crucial for successful treatment. Echinocandin antifungal drugs are first-line agents; however, their clinical effectiveness is highly variable, with known potential for breakthrough resistance, and little is known about drug exposure at the site of infection. Using matrix-assisted desorption ionization mass spectrometry imaging technology, we investigated the spatial and quantitative distribution in tissue lesions for two echinocandin drugs, micafungin and CD101, in a clinically relevant IAC mouse model. Drug accumulation within lesions was observed with both drugs at their humanized therapeutic doses. CD101, but not micafungin, accumulated in lesions at levels above the mutant prevention concentration of the infecting strain. These findings indicate that current echinocandin drugs are limited by penetration at the site of infection and have implications for clinical outcomes and emergence of resistance in patients with IAC.

Abstract
INTRODUCTION Delayed initial antifungal therapy is associated with high mortality rates caused by invasive candida infections, since accurate detection of the opportunistic pathogenic yeast and its identification display a diagnostic challenge. diagnosis of candida infections relies on time-consuming methods such as blood cultures, serologic and histopathologic examination. to allow for fast detection and characterization of invasive candidiasis, there is a need to improve diagnostic tools. trends in diagnostics switch to non-culture-based methods, which allow specified diagnosis within significantly shorter periods of time in order to provide early and appropriate antifungal treatment. Areas covered: within this review comprise novel pathogen- and host-related testing methods, e.g. multiplex-PCR analyses, T2 magnetic resonance, fungus-specific DNA microarrays, microRNA characterization or analyses of IL-17 as biomarker for early detection of invasive candidiasis. Expert commentary: Early recognition and diagnosis of fungal infections is a key issue for improved patient management. As shown in this review, a broad range of novel molecular based tests for the detection and identification of Candida species is available. However, several assays are in-house assays and lack standardization, clinical validation as well as data on sensitivity and specificity. This underscores the need for the development of faster and more accurate diagnostic tests.

Abstract
BACKGROUND Previous evidence-based guidelines on the management of intra-abdominal infection (IAI) were published by the Surgical Infection Society (SIS) in 1992, 2002, and 2010. At the time the most recent guideline was released, the plan was to update the guideline every five years to ensure the timeliness and appropriateness of the recommendations. METHODS Based on the previous guidelines, the task force outlined a number of topics related to the treatment of patients with IAI and then developed key questions on these various topics. All questions were approached using general and specific literature searches, focusing on articles and other information published since 2008. These publications and additional materials published before 2008 were reviewed by the task force as a whole or by individual subgroups as to relevance to individual questions. Recommendations were developed by a process of iterative consensus, with all task force members voting to accept or reject each recommendation. Grading was based on the GRADE (Grades of Recommendation Assessment, Development, and Evaluation) system; the quality of the evidence was graded as high, moderate, or weak, and the strength of the recommendation was graded as strong or weak. Review of the document was performed by members of the SIS who were not on the task force. After responses were made to all critiques, the document was approved as an official guideline of the SIS by the Executive Council. RESULTS This guideline summarizes the current recommendations developed by the task force on the treatment of patients who have IAI. Evidence-based recommendations have been made regarding risk assessment in individual patients; source control; the timing, selection, and duration of antimicrobial therapy; and suggested approaches to patients who fail initial therapy. Additional recommendations related to the treatment of pediatric patients with IAI have been included. SUMMARY The current recommendations of the SIS regarding the treatment of patients with IAI are provided in this guideline.

Abstract
BACKGROUND The frequency of Candida isolates as a cause of hospital infections has risen in recent years, leading to high rates of morbidity and mortality. The knowledge of the epidemiology of those hospital acquired fungal infections is essential to implement an adequate antifungal therapy. AIMS To describe the epidemiology of Candida infections in Intensive Care Units (ICUs) from a surveillance network in Colombia. METHODS Information was collected from the microbiology laboratories of 20 tertiary healthcare institutions from 10 Colombian cities using the Whonet® software version 5.6. A general descriptive analysis of Candida species and susceptibility profiles focusing on fluconazole and voriconazole was completed between 2010 and 2013, including a sub-analysis of healthcare associated infections (HAIs) during the last year. RESULTS Candida isolates made up 94.5% of the 2680 fungal isolates considered, with similar proportions for Candida albicans and non-C. albicans Candida species (48.3% and 51.7%, respectively). Among the latter, Candida tropicalis (38.6%) and Candida parapsilosis (28.5%) were the most frequent species. Of note, among the blood isolates C. albicans was not the main species. Most of the species isolated were susceptible to fluconazole and voriconazole. From the HAIs reported, 25.5% were caused by Candida; central line-associated bloodstream infection was the most common HAI (58.8%). There were no statistically significant differences regarding length of hospital stay and device days among HAIs. CONCLUSIONS In ICUs of Colombia, non-C. albicans Candida species are as frequent as C. albicans, except in blood samples where non-C. albicans Candida isolates predominate. Further studies are needed to evaluate Candida associated risk factors and to determine its clinical impact.

Morphology-Independent Virulence of Candida Species during Polymicrobial Intra-abdominal Infections with Staphylococcus aureus. Infect Immun 2015; 84:90-8.

Abstract
Intra-abdominal polymicrobial infections cause significant morbidity and mortality. An experimental mouse model of Candida albicans-Staphylococcus aureus intra-abdominal infection (IAI) results in 100% mortality by 48 to 72 h postinoculation, while monomicrobial infections are avirulent. Mortality is associated with robust local and systemic inflammation without a requirement for C. albicans morphogenesis. However, the contribution of virulence factors coregulated during the yeast-to-hypha transition is unknown. This also raised the question of whether other Candida species that are unable to form hyphae are as virulent as C. albicans during polymicrobial IAI. Therefore, the purpose of this study was to evaluate the ability of non-albicans Candida (NAC) species with various morphologies and C. albicans transcription factor mutants (efg1/efg1 and cph1/cph1) to induce synergistic mortality and the accompanying inflammation. Results showed that S. aureus coinoculated with C. krusei or C. tropicalis was highly lethal, similar to C. albicans, while S. aureus-C. dubliniensis, S. aureus-C. parapsilosis, and S. aureus-C. glabrata coinoculations resulted in little to no mortality. Local and systemic interleukin-6 (IL-6) and prostaglandin E2 (PGE2) levels were significantly elevated during symptomatic and/or lethal coinfections, and hypothermia strongly correlated with mortality. Coinoculation with C. albicans strains deficient in the transcription factor Efg1 but not Cph1 reversed the lethal outcome. These results support previous findings and demonstrate that select Candida species, without reference to any morphological requirement, induce synergistic mortality, with IL-6 and PGE2 acting as key inflammatory factors. Mechanistically, signaling pathways controlled by Efg1 are critical for the ability of C. albicans to induce mortality from an intra-abdominal polymicrobial infection.

Abstract
BACKGROUND/PURPOSE Although patients suffering community-acquired perforated peptic ulcer (PPU)-associated peritonitis with Candida species isolated from their peritoneal fluid have higher chances of mortality and experiencing a complicated postoperative clinical course, universal antifungal therapy for these patients remains controversial. METHODS This is a retrospective analysis of the impacts of antifungal therapy on outcomes of patients suffering community-acquired PPU-associated peritonitis with Candida species isolated from their ascites at a medical center in Taiwan. All included patients received source control and antibiotic treatment, with or without additional postoperative antifungal therapy with fluconazole or an echinocandin for at least 3 days. RESULTS Among the 133 included patients, 76 did not receive (Group 1) and 57 did receive (Group 2) antifungal therapy. Sixteen (12%) of the overall included patients died within 30 days. Shock [odds ratio (OR), 5.6; 95% confidence interval (CI), 1.9-16.5; p = 0.002] and higher Acute Physiology and Chronic Health Evaluation II score (>20; OR, 9.5; 95% CI, 1.1-80.7; p = 0.04) were independently associated with 30-day mortality. Among the 80 matched patients from Groups 1 and 2 (1:1 matched) with the closest propensity score, no significant difference was found in 30-day all-cause mortality, time to mortality, the need for reoperation/abscess formation/anastomotic leakage, prolonged intensive care unit stay, and prolonged mechanical ventilator dependence between patients with and without antifungal therapy. CONCLUSION Our study provides solid evidence supporting the notions that antifungal therapies do not benefit patients suffering PPU peritonitis with Candida species isolated from their ascites in general, and antifungal therapy could be reserved for patients who are critically ill and/or severely immunocompromised.

Abstract
PURPOSE Clinical data on patients with intra-abdominal candidiasis (IAC) is still scarce. METHODS We collected data from 13 hospitals in Italy, Spain, Brazil, and Greece over a 3-year period (2011-2013) including patients from ICU, medical, and surgical wards. RESULTS A total of 481 patients were included in the study. Of these, 27% were hospitalized in ICU. Mean age was 63 years and 57% of patients were male. IAC mainly consisted of secondary peritonitis (41%) and abdominal abscesses (30%); 68 (14%) cases were also candidemic and 331 (69%) had concomitant bacterial infections. The most commonly isolated Candida species were C. albicans (n = 308 isolates, 64%) and C. glabrata (n = 76, 16%). Antifungal treatment included echinocandins (64%), azoles (32%), and amphotericin B (4%). Septic shock was documented in 40.5% of patients. Overall 30-day hospital mortality was 27% with 38.9% mortality in ICU. Multivariate logistic regression showed that age (OR 1.05, 95% CI 1.03-1.07, P < 0.001), increments in 1-point APACHE II scores (OR 1.05, 95% CI 1.01-1.08, P = 0.028), secondary peritonitis (OR 1.72, 95% CI 1.02-2.89, P = 0.019), septic shock (OR 3.29, 95% CI 1.88-5.86, P < 0.001), and absence of adequate abdominal source control (OR 3.35, 95% CI 2.01-5.63, P < 0.001) were associated with mortality. In patients with septic shock, absence of source control correlated with mortality rates above 60% irrespective of administration of an adequate antifungal therapy. CONCLUSIONS Low percentages of concomitant candidemia and high mortality rates are documented in IAC. In patients presenting with septic shock, source control is fundamental.

Abstract
FKS mutant Candida isolates were recovered from 24% (6/25) of abdominal candidiasis patients exposed to echinocandin. Candida glabrata (29%) and Candida albicans (14%) mutants were identified. Multidrug-resistant bacteria were recovered from 83% of FKS mutant infections. Mutations were associated with prolonged echinocandin exposure (P = 0.01), breakthrough infections (P = 0.03), and therapeutic failures despite source control interventions (100%). Abdominal candidiasis is a hidden reservoir for the emergence of echinocandin-resistant Candida.

Abstract
BACKGROUND Abdominal infections are frequent causes of sepsis and septic shock in the intensive care unit (ICU) and are associated with adverse outcomes. We analyzed the characteristics, treatments and outcome of ICU patients with abdominal infections using data extracted from a one-day point prevalence study, the Extended Prevalence of Infection in the ICU (EPIC) II. METHODS EPIC II included 13,796 adult patients from 1,265 ICUs in 75 countries. Infection was defined using the International Sepsis Forum criteria. Microbiological analyses were performed locally. Participating ICUs provided patient follow-up until hospital discharge or for 60 days. RESULTS Of the 7,087 infected patients, 1,392 (19.6%) had an abdominal infection on the study day (60% male, mean age 62 ± 16 years, SAPS II score 39 ± 16, SOFA score 7.6 ± 4.6). Microbiological cultures were positive in 931 (67%) patients, most commonly Gram-negative bacteria (48.0%). Antibiotics were administered to 1366 (98.1%) patients. Patients who had been in the ICU for ≤ 2 days prior to the study day had more Escherichia coli, methicillin-sensitive Staphylococcus aureus and anaerobic isolates, and fewer enterococci than patients who had been in the ICU longer. ICU and hospital mortality rates were 29.4% and 36.3%, respectively. ICU mortality was higher in patients with abdominal infections than in those with other infections (29.4% vs. 24.4%, p < 0.001). In multivariable analysis, hematological malignancy, mechanical ventilation, cirrhosis, need for renal replacement therapy and SAPS II score were independently associated with increased mortality. CONCLUSIONS The characteristics, microbiology and antibiotic treatment of abdominal infections in critically ill patients are diverse. Mortality in patients with isolated abdominal infections was higher than in those who had other infections.

Abstract
The pathogenesis of Candida glabrata infections is poorly understood. We studied the pathogenesis of intra-abdominal candidiasis (IAC) in mice that were infected intraperitoneally with C. glabrata and sterile feces. C. glabrata BG2 (5 × 10(8) CFU) caused a 100% mortality rate. Sublethal inocula of BG2 (1 × 10(8) or 1 × 10(7) CFU) caused peritonitis that progressed to abscesses. Three clinical C. glabrata strains (5 × 10(8) CFU) caused 80 to 100% mortality rates, while a fourth (strain 346) caused a 29% mortality rate. Following sublethal inocula (1 × 10(7) CFU), the intra-abscess burdens of virulent strain 356 were ∼1 log greater than those of strain 346. A C. glabrata Δplb1-2 mutant (phospholipase B genes disrupted) killed mice as well as BG2 did. When sublethal inocula were used, however, the Δplb1-2 mutant was associated with more rapid abscess resolution and lower intra-abscess burdens; these findings were reversed by PLB1 and PLB2 reinsertion. The Δplb1-2 mutant was also more susceptible than BG2 to killing by human neutrophils in vitro. BG2 and the Δplb1-2 mutant were indistinguishable during hematogenously disseminated candidiasis. C. albicans SC5314 was more virulent than C. glabrata BG2 during IAC, causing a 100% mortality rate following a challenge with 5 × 10(7) CFU. In contrast, a sublethal inoculum (1 × 10(7) CFU) of BG2 caused less neutrophil infiltration and greater burdens in peritoneal fluid than SC5314 did and abscesses that persisted longer and contained greater burdens. In conclusion, a mouse model of C. glabrata IAC mimics disease in humans and distinguishes the relative virulence of clinical and gene disruption strains. C. glabrata differed from C. albicans during IAC by being less lethal and eliciting dampened neutrophil responses but resulting in more persistent peritonitis and abscesses.

Abstract
PURPOSE OF REVIEW The clinical spectrum of intra-abdominal fungal infections has not been systematically analyzed in the literature. RECENT FINDINGS Even though intra-abdominal fungal infections have been recognized with increasing frequency in the recent years, most clinical experience is limited to case reports or uncontrolled case series. These infections are more common than clinically recognized disease. The clinical presentation varies broadly depending on the organism and host's immune status, but it is frequently severe, difficult to treat, and associated with significant morbimortality. Predisposing factors, clinical characteristics, and advances in the management are discussed. SUMMARY Intra-abdominal fungal infections are increasingly important in clinical practice. Early recognition and a combined treatment approach, usually consisting of surgical intervention and systemic antifungal therapy, are required for improved outcomes.

Abstract
BACKGROUND The pathogenesis of intra-abdominal candidiasis is poorly understood. METHODS Mice were intraperitoneally infected with Candida albicans (1 × 10(6) colony-forming units) and sterile stool. nanoString assays were used to quantitate messenger RNA for 145 C. albicans genes within the peritoneal cavity at 48 hours. RESULTS Within 6 hours after infection, mice developed peritonitis, characterized by high yeast burdens, neutrophil influx, and a pH of 7.9 within peritoneal fluid. Organ invasion by hyphae and early abscess formation were evident 6 and 24 hours after infection, respectively; abscesses resolved by day 14. nanoString assays revealed adhesion and responses to alkaline pH, osmolarity, and stress as biologic processes activated in the peritoneal cavity. Disruption of the highly-expressed gene RIM101, which encodes an alkaline-regulated transcription factor, did not impact cellular morphology but reduced both C. albicans burden during early peritonitis and C. albicans persistence within abscesses. RIM101 influenced expression of 49 genes during intra-abdominal candidiasis, including previously unidentified Rim101 targets. Overexpression of the RIM101-dependent gene SAP5, which encodes a secreted protease, restored the ability of a rim101 mutant to persist within abscesses. CONCLUSIONS A mouse model of intra-abdominal candidiasis is valuable for studying pathogenesis and C. albicans gene expression. RIM101 contributes to persistence within intra-abdominal abscesses, at least in part through activation of SAP5.

Abstract
Despite advances in medical device fabrication and antimicrobial treatment therapies, fungal-bacterial polymicrobial peritonitis remains a serious complication for surgery patients, those on peritoneal dialysis, and the critically ill. Using a murine model of peritonitis, we have demonstrated that monomicrobial infection with Candida albicans or Staphylococcus aureus is nonlethal. However, coinfection with these same doses leads to a 40% mortality rate and increased microbial burden in the spleen and kidney by day 1 postinfection. Using a multiplex enzyme-linked immunosorbent assay, we have also identified a unique subset of innate proinflammatory cytokines (interleukin-6, granulocyte colony-stimulating factor, keratinocyte chemoattractant, monocyte chemoattractant protein-1, and macrophage inflammatory protein-1α) that are significantly increased during polymicrobial versus monomicrobial peritonitis, leading to increased inflammatory infiltrate into the peritoneum and target organs. Treatment of coinfected mice with the cyclooxygenase (COX) inhibitor indomethacin reduces the infectious burden, proinflammatory cytokine production, and inflammatory infiltrate while simultaneously preventing any mortality. Further experiments demonstrated that the immunomodulatory eicosanoid prostaglandin E2 (PGE2) is synergistically increased during coinfection compared to monomicrobial infection; indomethacin treatment also decreased elevated PGE2 levels. Furthermore, addition of exogenous PGE2 into the peritoneal cavity during infection overrode the protection provided by indomethacin and restored the increased mortality and microbial burden. Importantly, these studies highlight the ability of fungal-bacterial coinfection to modulate innate inflammatory events with devastating consequences to the host.

Abstract
PURPOSE This study evaluates the effect of peritoneal irrigation and drainage on postoperative morbidity when used together for perforated appendicitis. MATERIAL AND METHODS This study was conducted on children undergoing open appendectomy for perforated appendicitis. Sixty-one children with perforated appendicitis operated on with irrigation and drainage between July 1998 and September 2001 (group DI) and 173 children with perforated appendicitis who underwent surgery without irrigation and drainage (group NDI) between October 2001 and November 2011 were retrospectively evaluated (a total of 234 patients). All patients were treated and followed up by the same pediatric surgeon using the same protocol. Both groups were compared in respect to postoperative complications, including wound infection, wound dehiscence, intraabdominal abscess, prolonged ileus, the presence of small bowel obstruction requiring surgery, operative time, and length of postoperative hospital stay. RESULTS Of the total 234 patients, 151 were male and 83 were female with a mean age of 8.9 ± 3.7 years (range, 1.5-15 years). The wound infection rates were 4.9% in group DI and 1.7% in group NDI (P = .184). Wound dehiscence was seen in 1.6% vs 0%, prolonged ileus in 8% vs 2.3%, intraabdominal abscess in 4.9% vs 1.7%, and small bowel obstruction requiring surgery in 1.6% vs 0.6% of the patients (P = .261, P = .054, P = .184, and P = .454, respectively). No statistically significant difference in postoperative infectious complications was found between both groups. The length of postoperative hospital stay was 9.9 ± 4.1 days in group DI vs 6.3 ± 2.4 days in group NDI (P < .001). The operation times were 39 ± 8 and 31 ± 11 minutes, respectively (P < .001). CONCLUSION This study demonstrates that peritoneal irrigation and drainage in children with perforated appendicitis is not required, and in fact, these procedures cause an increase in operative time.
