Abstract
Purpose
The aim of this document was to develop standardized research definitions of invasive fungal diseases (IFD) in non-neutropenic, adult patients without classical host factors for IFD, admitted to intensive care units (ICUs).
Methods
After a systematic assessment of the diagnostic performance for IFD in the target population of already existing definitions and laboratory tests, consensus definitions were developed by a panel of experts using the RAND/UCLA appropriateness method.
Results
Standardized research definitions were developed for proven invasive candidiasis, probable deep-seated candidiasis, proven invasive aspergillosis, probable invasive pulmonary aspergillosis, and probable tracheobronchial aspergillosis. The limited evidence on the performance of existing definitions and laboratory tests for the diagnosis of IFD other than candidiasis and aspergillosis precluded the development of dedicated definitions, at least pending further data. The standardized definitions provided in the present document are aimed to speed-up the design, and increase the feasibility, of future comparative research studies.

Introduction
Invasive fungal diseases (IFD) are widely recognized as a cause of morbidity and mortality in immunocompromised patients, but can also occur in non-neutropenic, adult patients admitted to intensive care unit (ICU), without classical host factors for IFD [1,2,3,4,5].
The population of non-neutropenic, critically ill adult patients is highly heterogenous, including medical and surgical patients, with a wide range of baseline comorbidities and predisposing conditions for IFD [6,7,8,9,10,11,12]. Together with the frequent absence of classical host factors predisposing to IFD, such as neutropenia, hematological malignancies, or solid organ transplantation (SOT), this wide heterogeneity has led to the development of different definitions of IFD in this patient population, each with different denominators (i.e., different subgroups of critically ill patients by predisposing factors/conditions) [13,14,15,16,17,18,19]. While certainly useful for providing information on the burden of IFD and for increasing awareness and recognition of IFD in specific categories of critically ill patients (e.g., patients with chronic obstructive pulmonary disease [COPD], influenza, or coronavirus disease 2019 [COVID-19]), these definitions remain of limited generalizability outside the specific populations for which they were developed.
The Invasive Fungal Diseases in Adult Patients in ICU (FUNDICU) project was conceived with the aim of developing a standard set of definitions for IFD in non-neutropenic, ICU patients outside the classical immunocompromised patient populations, which could improve the generalizability and comparability of research results. The FUNDICU definitions have been developed for clinical research, and not for clinical practice. Furthermore, they are not meant to replace but rather to complement the definitions of IFD provided by the European Organization for Research and Treatment of Cancer (EORTC) and the Mycoses Study Group Education and Research Consortium (MSGERC) [20]. The EORTC/MSGERC consensus document remains the reference for standardized IFD definitions in patients with classical host factors, even when they are admitted to the ICU. More in detail, the definitions of IFD included in the present document do not apply to those ICU patients who fulfill the EORTC/MSGERC host factors: (i) hematology and SOT patients; (ii) prolonged use of corticosteroids; (iii) treatment with other recognized T-cell immunosuppressants; (iv) treatment with recognized B-cell immunosuppressants; (v) inherited severe immunodeficiency; (vi) acute graft-versus-host disease grade III or IV involving the gut, lung, or liver and refractory to first-line treatment with steroids [20].
Methods
The detailed protocol of the FUNDICU project has been published previously [21]. A multidisciplinary panel of experts was selected by the chairs of the Critically Ill Patients Study Group (ESGCIP) and the Fungal Infections Study Group (EFISG) of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) [21]. The panel was approved by the Executive Committees of ESGCIP and EFISG, and then by the relevant bodies/committees of the European Society of Intensive Care Medicine (ESICM), the European Confederation of Medical Mycology (ECMM), and the MSGERC [21]. The second step was to identify the existing relevant literature on the performance of existing definitions and tests for the diagnosis of different IFDs in the target population. Four different systematic reviews were conducted, with subsequent updates of the literature searches up to 31 March 2022. Their results were published and used to develop the initial definitions, which were discussed and approved by the expert panel [22,23,24,25]. The definitions were then evaluated by the expert panel using the RAND/UCLA appropriateness method [26]. Briefly, each member of the expert panel rated each of the proposed definitions from 1 to 9 using the REDCap electronic data capture software (with 1 and 9 indicating “inappropriate” and “fully appropriate” definitions, respectively) [27]. After all experts had voted, the median score was used to classify each of the rated definitions as follows: (i) inappropriate (score 1–3); (ii) possibly considered (score 4–6); (iii) appropriate (score 7–9). During the rating process, experts were also given the opportunity to provide alternative definitions [21]. A total of two voting rounds were necessary to rate initial and alternative definitions. Finally, definitions ranked as “appropriate” or “possibly considered” were discussed by the panel during an online meeting with an anonymized vote for acceptance or rejection. Participants were also offered the possibility to select no preference over agreement or rejection (neutral votes). Consensus was defined as a ≥ 70% agreement towards acceptance with < 15% disagreement (with the denominator also including neutral votes) [28]. A total of three voting rounds preceded by dedicated discussions and modifications were necessary during the online meeting to achieve provisional consensus on all proposed definitions. Then, a fourth round of remote voting of definitions was conducted after peer review to discuss and evaluate reviewers’ comments, even for minor text changes for fluency. The voting round after peer review was performed to consider suggestions provided by referees during the peer-review process without losing the rigorous methodological approach for consensus achievement adopted in the previous phases. Changes were implemented only in case of ≥ 70% agreement towards acceptance with < 15% disagreement. Deviations from the original protocol are reported and justified in the supplementary material.
Invasive candidiasis
Background
Invasive candidiasis (IC) is the most common IFD in non-neutropenic, critically ill adult patients in the ICU, and is associated with high mortality that may exceed 50% in patients presenting with septic shock [2, 6, 29,30,31,32,33,34,35,36]. Invasive candidiasis develops when Candida spp., common colonizers of the skin and mucosal surfaces, invade the normally sterile compartments of the body [37, 38]. IC can be divided into two non-mutually exclusive forms: (i) candidemia; (ii) deep-seated candidiasis. The most common form of deep-seated candidiasis in non-neutropenic, critically ill patients in the ICU is intra-abdominal candidiasis (IAC) [6, 8, 31, 39].
Development process for invasive candidiasis definitions
Isolation of Candida spp. from at least one blood culture obtained from venipuncture (not from a catheter) is an unequivocal evidence (proven diagnosis) of candidemia, which is the most common form of proven IFD in non-neutropenic, critically ill adult ICU patients [2, 8, 37].
When a proven diagnosis of IC is not available or difficult to achieve, patients with a high probability of IC can still be included in research studies. To define probable IC for research purposes, the expert panel evaluated (in the presence of consistent clinical criteria) the role of cultures from non-sterile sites and fungal antigen-based biomarkers [24]. Regarding fungal antigen-based biomarkers, most of the available evidence in non-neutropenic, critically ill adult patients is limited to the serum biomarker (1,3)-β-D-glucan (BDG). The positive predictive value (PPV) of BDG varies widely between studies, possibly reflecting the prevalence of IC in the study population and its targeted or untargeted use (e.g., the PPV of BDG is expected to be the highest in the subgroup of patients with signs and symptoms of infection and risk factors for IC), but the use of different BDG cut-offs in the different studies [24] may also influence the results.
The panel eventually decided not to develop a “probable” category for research studies on candidemia. This decision was based on the fact that blood cultures are always obtained in patients with suspected candidemia and, if collected properly through venipuncture (two pairs of blood culture bottles of 10 mL each for aerobic and anaerobic culture before initiating any antifungal therapy [40]), their sensitivity could potentially increase to 70–80% by augmenting the number of blood cultures pairs collected over 24 h [39]. Therefore, a large number of patients with proven candidemia (or without candidemia if a sufficient number of negative blood cultures have been collected to provide a reliable reference standard) can usually be identified and included in research studies. On the other hand, a plausible argument for developing a definition of probable candidemia is to consider positivity of blood cultures from at least two sites (e.g., from a central venous catheter and from an arterial catheter) when venipuncture is not available. The panel will consider this possibility in future updates of the consensus document, if restriction to proven diagnosis by venipuncture will eventually prove insufficient to achieve adequate sample sizes in research studies.
The scenario is different for deep-seated candidiasis, for which a proven diagnosis is usually less frequently obtained than for candidemia, and for which cultures from non-sterile sites and fungal antigen-based biomarkers (in particular serum BDG, to which most of the available evidence refers, see above) could be considered for defining probable IC in research studies. Important limitations to recognize are that the use of fungal antigen-based biomarkers in deep-seated candidiasis is still not standardized and that they could be hampered by low specificity for defining probable IC for research purposes. Furthermore, most evidence on their use in critically ill adult patients comes from studies evaluating candidemia or IC in general (i.e., both candidemia and deep-seated candidiasis) [24]. After careful consideration and discussion, the panel ultimately agreed that serum BDG positivity may not achieve sufficient specificity in the target population as a mycological criterion to be used in conjunction with at least one clinical criterion to define “probable” deep-seated candidiasis in research studies. Implementation of serum BDG as a mycological criterion was the most debated topic during consensus development. It was initially included in the provisional definition, although, while the panel almost unanimously agreed on the other mycological criteria, major comments regarding serum BDG inclusion highlighted its possible low specificity for defining probable deep-seated candidiasis for research purposes. Discussions were protracted after peer review, when it was eventually agreed not to include serum BDG as mycological criterion for the current FUNDICU research definition for probable deep-seated candidiasis, at least pending further evidence.
An even more difficult task is to define IC when its presence is suspected clinically but the criteria for either proven or probable IC are not fulfilled. The expert panel considered once again (as for the use of antigen-based biomarkers for probable deep-seated candidiasis, see above) that a crucial aspect in developing research definitions is the conceptual distinction between clinical suspicion of IC (which may lead to early therapy in the daily clinical practice) and the definition of IC intended for research purposes. Specifically, a low but non-negligible probability of IC may prompt empirical antifungal therapy in patients with severe clinical presentation (i.e., septic shock) in clinical practice, but may not be sufficient to ensure homogeneity and control for confounding when defining IC for research purposes. For this reason, the panel ultimately decided not to develop a “possible” category for the definition of IC. Indeed, according to the results of the baseline systematic review conducted to support the development of this document [24], the definition of a “possible IC” category would have carried an unacceptable risk of including a large proportion of patients without IC, thereby precluding reliable comparison and generalization of research results.
Definitions of proven invasive candidiasis and probable deep-seated candidiasis
The developed definitions of proven IC and probable deep-seated candidiasis in non-neutropenic, critically ill adult ICU patients without classical host factors for IFD are detailed in Tables 1 and 2, respectively. A flowchart to identify patients fulfilling the definition of probable deep-seated candidiasis is also displayed in Fig. 1.
Proven invasive candidiasis
The expert panel universally agreed that the identification of Candida spp. from normally sterile sites defines IC (either candidemia or deep-seated candidiasis). Identification can be made by direct microscopy, culture, or histology. The histological evidence of budding cells consistent with Candida spp. directly defines proven invasive candidiasis, whereas species identification by polymerase chain reaction (PCR) or culture is required for hyphae or pseudohyphae, which may also be observed with other yeasts [37].
Probable deep-seated candidiasis
The presence of at least one mycological criterion and at least one clinical criterion is necessary for defining probable deep-seated candidiasis, as agreed upon by the panel. Two mycological criteria were eventually defined. The first one is recovery of Candida spp. from a specimen collected in a sterile manner from an abdominal, mediastinal, or pleural space or abscess/empyema after alteration of the gastrointestinal or urogenital wall integrity (perforation/surgery). Specimens should preferably be obtained during surgery or from a ultrasound (US)-guided or computerized tomography (CT)-guided aspirate or from a newly inserted drain no later than 24 h after placement [41]. However, contamination of specimens obtained from colonized drains should always be considered. In particular, this mycological criterion does not apply to the isolation of Candida spp. from peritoneal fluid after gastrointestinal or urogenital perforation if source control is rapidly achieved (within 24 h from perforation and after peritoneal fluid collection). A similar situation may reflect contamination prior to the development of invasive disease. In the case of source control performed more than 24 h after perforation or in the case of recurrent peritonitis (e.g., anastomotic leakage), isolation of Candida spp. from the peritoneum (from an intra-abdominal specimen during surgery or obtained from an external drainage inserted within 24 h) defines a mycological criterion for probable deep-seated candidiasis. The same concepts apply to Candida mediastinitis and pleuritis/empyema following esophageal perforation. The second mycological criterion is as follows: for other deep sites (and for the mediastinum and the abdomen in the absence of perforation), the presence of concomitant proven candidemia can be considered as a mycological criterion for probable deep-seated candidiasis. In this latter case, the disease should be classified as proven IC in research studies (proven candidemia plus probable deep-seated candidiasis).
Regarding clinical criteria, the following were defined: (i) funduscopic lesions compatible with invasive candidiasis or (ii) radiological abnormalities consistent with an infectious disease process that remain unexplained after investigation for other infectious/non-infectious processes; these abnormalities should be present in sites where IC could develop either because of direct inoculation or because of previous unrecognized hematogenous spread (e.g., IAC, endocarditis, osteomyelitis, arthritis, mediastinitis, meningitis); very importantly, the investigations undertaken for excluding alternative diagnoses should be reported in detail in all research studies in which the probable deep-seated candidiasis definition is employed.
Of note, the systematic reviews that underpinned the development of this document highlighted that very few studies investigating the performance of PCR (including assays exploiting miniaturized magnetic resonance technology) for the diagnosis of IC on blood cultures or other deep specimens met the inclusion criteria necessary to reliably assess the role of PCR in defining IC in non-neutropenic, critically ill adult ICU patients without classical host factors for IFD. The same applies to fungal antigen-based biomarkers other than BDG and to combinations of biomarkers. Nevertheless, the panel strongly recognizes that both PCR and fungal antigen-based tests (including further investigation on BDG in the target population) represent an important area of future research in an attempt to improve current IC diagnosis for both research and clinical purposes in the target population.
Invasive aspergillosis
Background
Invasive aspergillosis (IA) has traditionally been reported in classical at-risk populations, such as hematology or SOT patients [20, 42, 43]. However, IA can also develop outside these classical categories. In non-neutropenic, adult ICU patients, IA usually presents as invasive pulmonary aspergillosis (IPA), which poses particular diagnostic challenges: (i) the classical radiological features of IPA (e.g., halo or air crescent sign) described in immunocompromised patients are often absent; (ii) non-culture-based tests such as galactomannan and DNA amplification may have lower diagnostic accuracy than in classical at-risk populations [1, 22, 44,45,46,47,48,49,50,51,52,53]. These problems could be overcome by proven diagnosis requiring histology. However, obtaining samples for histology by biopsy of infected tissue is often not feasible, e.g., due to hemodynamic instability, mechanical ventilation, or coagulopathy. For this reason, various definitions of probable IA for use in critically ill ICU patients have been proposed over the years [14,15,16,17,18,19]. However, although they are certainly useful, they are not based on a broad consensus and/or are limited to very specific categories of ICU patients, which precludes their generalization. Another diagnostic challenge is that distinguishing Aspergillus colonization from IA in non-neutropenic, adult patients in ICU may be more difficult in the absence of classical host factors.
Development process for invasive aspergillosis definitions
The non-specific clinical/radiological presentation and the wide heterogeneity of predisposing conditions remain important issues when attempting to develop a universal definition of IA in non-neutropenic adult ICU patients without classical host factors. The results of the systematic review conducted to support the development of the present document resulted in the identification of common features in the performance of existing definitions and laboratory tests, which ultimately helped to achieve consensus [22, 25]. Specifically, (i) although based on small samples, the existing AspICU definition of putative IPA showed a good ability to discriminate between colonization and infection in critically ill patients with positive respiratory cultures, when tested against the proper diagnostic reference (autopsy/histology); (ii) the diagnostic performance of bronchoalveolar lavage fluid (BALF) galactomannan was better than that of serum galactomannan in the target population; (iii) BALF and serum BDG consistently showed suboptimal specificity for the diagnosis of IPA in non-neutropenic, adult ICU patients [22, 25]. With this baseline information, and after sharing opinions and experiences related to the application of concepts developed for other patient populations, the expert panel was finally able to reach a consensus on the definitions of proven IA and probable IPA/tracheobronchial aspergillosis (TBA) in non-neutropenic, critically ill adult ICU patients without classical host factors. The panel decided against developing a “possible” category of IA for research purposes. Yet, it did not discourage the use of the possible definition developed elsewhere for specific ICU populations (e.g., patients with COVID-19-associated pulmonary aspergillosis [CAPA]) to target early antifungal treatment in selected situations in clinical practice [16, 18].
Three important points need to be discussed more in detail. First, while the definition of proven IA is inherently applicable to all forms of IA (not only pulmonary), the evidence that led to the development of the definition of probable IA in the current document was limited to IPA and TBA. Therefore, the panel did not consider it feasible to define probable IA for forms other than IPA and TBA, pending further evidence. Second, as anticipated above, the panel did not support to develop a definition of possible IPA/TBA for research purposes. In clinical practice, physicians may decide to administer antifungals in selected cases of suspected IPA/TBA that do not meet the definition for probable disease (e.g., critically ill patients with influenza or COVID-19 who have no alternative diagnoses, have positive mycological tests from non-bronchoscopic lavage, and do not respond to antibacterial therapy for pulmonary infiltrates) [19, 54, 55]. However, the number of false-positive tests in a possible category would be too high to avoid confounding the results of research studies, thereby compromising comparability and generalizability. Third, the presence of signs and symptoms defined in the AspICU criteria was considered by the panel as a necessary condition to evaluate patients for probable IPA/TBA (with very few exceptions, see below), to improve the chance of distinguishing true infection from colonization [14].
The definitions of probable IPA and probable TBA required prolonged discussions. While generic risk factors (e.g., short courses of corticosteroids) may prompt clinicians to consider antifungal therapy in selected cases, they are too vague to contribute defining probable IPA and probable TBA for research purposes. Rather than risk factors, the panel decided to define precise predisposing conditions, i.e., baseline conditions that carry a substantial risk of IA (eventually defined as ICU host factors). Surely, this could be seen as a conservative approach. However, it makes it possible to preserve comparability and generalization of research results without necessarily impacting on clinical practice (since physicians should follow guidelines for patient management rather than research definitions for early treatment decisions).
Definitions of proven invasive aspergillosis and probable invasive pulmonary aspergillosis/probable tracheobronchial aspergillosis
The definitions of proven IA and of probable IPA and probable TBA in non-neutropenic, critically ill adult ICU patients without classical host factors for IFD are detailed in Table 3 and Table 4, respectively. A flowchart to identify patients fulfilling the definition of probable IPA/probable TBA is also displayed in Fig. 2.
Proven invasive aspergillosis
The expert panel agreed to define proven IA in non-neutropenic, critically ill adult ICU patients without classical host factors as the combination of Aspergillus detection and tissue invasion. More in detail, proven IA is defined by the presence of tissue invasion demonstrated by histological or cytopathological evidence in a specimen obtained from a normally sterile site or the lung by biopsy or needle aspiration, combined with detection of hyphae compatible with Aspergillus spp. (confirmed by culture or PCR). Alternatively, the recovery from culture of Aspergillus spp. from a specimen obtained by biopsy or needle aspiration from a lesion consistent with an infectious process and obtained from a normally sterile site is also defined as proven IA.
Probable invasive pulmonary aspergillosis and probable tracheobronchial aspergillosis
To define probable IPA/TBA, the following should be present: (i) at least one compatible sign or symptom; (ii) at least one ICU host factor; (iii) at least one clinical criterion; (iv) at least one mycological criterion. The only allowed exception is probable TBA in patients with COVID-19 or influenza that can be defined also in the absence of compatible signs and symptoms (see Table 4 and Fig. 2).
Regarding compatible signs and symptoms, at least one of the following signs or symptoms should be present (and compatible with the site/progression of IPA or TBA) to proceed with the evaluation of the patients who may meet the definitions of probable IPA or probable TBA for research studies: (i) fever persisting after at least 3 days of appropriate antibiotic therapy (and source control for bacterial infection, if necessary); (ii) relapse of fever after a period of at least 48 h of defervescence while still on antibiotics and without other apparent causes; (iii) pleuritic chest pain; (iv) pleuritic rubbing of the lungs on examination; (v) dyspnea (not applicable for patients ventilated from more than 48 h at the time of assessment for probable IPA/TBA, and applicable in the first 48 h if dyspneic at the time of initiation of ventilation); (vi) hemoptysis; (vii) worsening respiratory insufficiency despite appropriate antibiotic therapy and ventilatory support [14].
ICU host factors include the following: (i) influenza; (ii) COVID-19; (iii) moderate/severe COPD; (iv) decompensated liver cirrhosis; (v) Uncontrolled infection by human immunodeficiency virus (HIV) with CD4 cell count < 200/mm3; (vi) solid tumors. The expert panel recognize the usefulness of existing consensus definitions for specific categories of ICU patients (i.e., patients with influenza or with COVID-19) as valuable baseline information for development of this document [16, 19].
Clinical criteria include the following: (i) presence of tracheobronchial ulceration and/or nodules and/or pseudomembrane and/or plaque, and/or eschar on bronchoscopy (to define probable TBA); (ii) presence of pulmonary infiltrate(s) by chest CT, or presence of cavitation not attributable to other causes (to define probable IPA).
With regard to the mycological criteria, the panel agreed on the following: (i) detection of mold elements in BALF by microscopy; (ii) positive Aspergillus BALF culture; (iii) serum galactomannan > 0.5 optical density index (ODI); (iv) BALF galactomannan ≥ 1.0 ODI. With regard to Aspergillus PCR, while its use in BALF, serum, plasma, and/or whole blood could be useful in clinical practice to identify patients with suspected IPA/TBA and could prompt early treatment (as such it is included in the clinical consensus definition for probable CAPA developed by the ECMM and the International Society for Human and Animal Mycology [ISHAM] [16]), the overall evidence regarding its general performance in non-neutropenic, critically ill ICU patients is still limited [22, 25]. Therefore, additional studies conducted in the target population may lead to the inclusion of PCR for the diagnosis of IA in future updates of the current definitions. In particular, this should not discourage the use of PCR as a mycological criterion in research studies conducted in patients with COVID-19 using the ECMM/ISHAM definition of probable CAPA as a reference standard, as this may provide indirect evidence of the suitability of PCR as a useful mycological criterion (e.g., indirect evidence arising from prognostic considerations). The same considerations generally apply to the Aspergillus lateral flow device (AspLFD) and the GM lateral flow assay galactomannan lateral flow assay (GM-LFA) [16]. The latest update of the systematic review on the diagnostic performance of laboratory tests for IPA provided some evidence on the use of BALF GM-LFA in the population of interest [25]. Although the sensitivity and specificity varied between studies, the panel eventually deemed it appropriate, when the Platelia test is unavailable, to suggest using other GM tests for defining probable IPA/TBA in research studies, provided they were compared with the Platelia test in well-designed studies and shown to have comparable specificity to the 1.0 Platelia cut-off. Overall, whenever available, the use of GM remains preferable for defining probable IPA/TBA in research studies in the population of interest, pending further evidence.
Other invasive fungal diseases
Definition development process
For IFD other than IC and IA, such as Pneumocystis jirovecii pneumonia (PJP), the systematic reviews supporting the development of this document highlighted the lack of sufficient evidence on the diagnostic performance of existing definitions and laboratory tests for their diagnosis in non-neutropenic, critically ill adult patients in the ICU [23]. While for proven IFD other than IA and IC, the expert panel suggested adhering to the definitions already provided in the EORTC/MSGERC consensus document [20], defining a probable category for these IFD was considered unfeasible in the population of interest. For this reason, dedicated initiatives have been started to assess the use and performance of diagnostic tests for IFD other than IC and IA in ICU patients [56, 57], aimed to support the development of definitions of probable disease in future updates of this document.
Conclusions
The FUNDICU consensus document provides definitions for IC and IA in non-neutropenic, adult patients in the ICU who do not fulfil the host factors included in the recent EORTC/MSGERC consensus document [20], for use in clinical research. Although many gaps remain, we hope that, if widely adopted, the standardized definitions provided in this document will facilitate the design of future research studies and increase the comparability of their results. The ultimate goal is to standardize the diagnosis of IFD and optimize the management and outcomes of critically ill patients with IFD.
