Doub JB, Siddiqui H. Propensity of Candida spp. prosthetic joint infection clinical isolates to form aggregates in synovial fluid and the clinical ramifications. Mycoses 2024; 67:e13769. [PMID: 39039764 DOI: 10.1111/myc.13769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 07/12/2024] [Accepted: 07/13/2024] [Indexed: 07/24/2024]
Abstract
BACKGROUND Bacterial aggregation has been shown to occur in synovial fluid which are resistant to high concentrations of antibiotics. Yet the propensity of Candida spp. to form aggregates is unknown. OBJECTIVE To assess the ability of numerous Candida spp. to form synovial fluid aggregates and the clinical ramifications of the aggregates. METHODS Nine different Candidal prosthetic joint infection clinical isolates were evaluated for their ability to form aggregates at static and dynamic conditions and their resistance to high concentrations of amphotericin. Furthermore, the ability of tissue plasminogen activator (TPA) to disrupt the aggregates and enhance amphotericin activity was assessed. RESULTS The results show that all species of Candida spp. evaluated formed aggregates in synovial fluid under dynamic conditions that were resistant to amphotericin. Yet no aggregates formed in tryptic soy broth under any conditions or in synovial fluid under static conditions. As well, when TPA was combined with amphotericin there was a statistically significant decrease (p < .005) in the amount of colony forming units per mL for all Candidal species evaluated. Interestingly, for Candida krusei there was no colony forming units observed after exposure to TPA and amphotericin. CONCLUSION Our findings suggest that Candidal species form synovial fluid aggregates that are resistant to high dose amphotericin similar to those that occur with bacteria. However, the varying ability of the different Candida spp. to form hyphae and pseudohyphae compared to yeast cells may have direct impacts on the hardiness of the aggregates and thereby have clinical ramifications with respect to treatment durations.

Braz J Microbiol 2024:10.1007/s42770-024-01418-7. [PMID: 38896342 DOI: 10.1007/s42770-024-01418-7] [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: 02/18/2024] [Accepted: 06/04/2024] [Indexed: 06/21/2024] Open
Abstract
Osteomyelitis caused by non-Candida species is rare and often neglected, and current recommendations are based on primarily clinical experience and expert opinion. The objective of this study was to describe a case series of non-Candida fungal osteomyelitis. This retrospective study included 10 patients with non-Candida fungal osteomyelitis. Patients with osteomyelitis and microbiologically confirmed non-Candida species from bone fragment cultures were selected from the institution Infection Control Board database. Fusarium spp. were the most commonly isolated fungus from bone fragment cultures in five patients (50%). The majority did not present immunosuppression. The most common etiology was post-traumatic (n = 7, 70%), particularly open fractures. All patients were treated with antifungals associated with surgery. The antifungals used were itraconazole in five patients (50%), and voriconazole in another five patients (50%), with a median duration of antifungal therapy of four weeks (range: 3-25). There were no observed deaths within 30 days and one year. An antifungal approach combined with surgical treatment demonstrated favorable clinical outcomes, including low mortality rates and effective remission.

Diagnosis, Treatment, and Outcome of Coccidioidal Osseous Infections: A Systematic Review. J Fungi (Basel) 2024; 10:270. [PMID: 38667941 PMCID: PMC11050809 DOI: 10.3390/jof10040270] [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: 03/08/2024] [Revised: 03/31/2024] [Accepted: 04/03/2024] [Indexed: 04/28/2024] Open
Abstract
Extrapulmonary infections by Coccidioides spp., though rare, can occur via dissemination, affecting singular or multiple sites, including the skin and musculoskeletal system. Skeletal involvement often manifests as osteomyelitis, particularly in the axial skeleton. The present systematic review evaluates all documented cases of skeletal coccidioidomycosis to assess the diagnostic and treatment strategies alongside the outcomes, drawing insights from an analysis of 163 verified cases. A systematic review following PRISMA guidelines identified all studies reporting skeletal infections by Coccidioides spp. up to 2023 from the PubMed and Scopus databases. Eligible studies evaluated osteoarticular infections from Coccidioides spp. Data extraction included demographics, microbiological data, diagnostic methods, and treatment outcomes. Of the 501 initially identified records, a total of 163 patients from 69 studies met the inclusion criteria. Most cases were from the USA, predominantly males, while the median age of the population was 36 years. Diabetes mellitus was the common comorbidity (14.7%). C. immitis was the most prevalent pathogen. The spine and hand were common sites of infection (17.5% and 15.1%, respectively). Osteomyelitis by Coccidioides spp. was diagnosed, in most cases, by positive cultures (n = 68; 41.7%), while, in 49 (30.9%), both the histological examination and cultures yielded the fungus. Surgical debridement was performed in 80.9% of cases. A total of 118 (72.3%) patients were treated with monotherapy, while combination therapy with two or more antifungal agents was reported in 45 (17.7%). Amphotericin B (either liposomal or deoxycholate) was the most commonly given agent as monotherapy in 51 (31.2%) patients, while 30 (18.4%) patients received itraconazole as monotherapy. The rate of infection's resolution was higher in patients undergoing surgical debridement (79.5%), compared to those treated only with antifungal agents (51.6%, p = 0.003). Treatment outcomes showed complete resolution in 74.2% of patients, with a mortality rate of 9.2%. Coccidioidal osseous infections present diagnostic and therapeutic challenges. Surgical intervention is often necessary, complementing antifungal therapy. Vigilance for Coccidioides spp. infections, especially in regions with endemicity, is crucial, particularly when bacterial cultures yield negative results.

Is Silver Addition to Scaffolds Based on Polycaprolactone Blended with Calcium Phosphates Able to Inhibit Candida albicans and Candida auris Adhesion and Biofilm Formation? Int J Mol Sci 2024; 25:2784. [PMID: 38474027 DOI: 10.3390/ijms25052784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 02/19/2024] [Accepted: 02/23/2024] [Indexed: 03/14/2024] Open
Abstract
Candida spp. periprosthetic joint infections are rare but difficult-to-treat events, with a slow onset, unspecific symptoms or signs, and a significant relapse risk. Treatment with antifungals meets with little success, whereas prosthesis removal improves the outcome. In fact, Candida spp. adhere to orthopedic devices and grow forming biofilms that contribute to the persistence of this infection and relapse, and there is insufficient evidence that the use of antifungals has additional benefits for anti-biofilm activity. To date, studies on the direct antifungal activity of silver against Candida spp. are still scanty. Additionally, polycaprolactone (PCL), either pure or blended with calcium phosphate, could be a good candidate for the design of 3D scaffolds as engineered bone graft substitutes. Thus, the present research aimed to assess the antifungal and anti-biofilm activity of PCL-based constructs by the addition of antimicrobials, for instance, silver, against C. albicans and C. auris. The appearance of an inhibition halo around silver-functionalized PCL scaffolds for both C. albicans and C. auris was revealed, and a significant decrease in both adherent and planktonic yeasts further demonstrated the release of Ag+ from the 3D constructs. Due to the combined antifungal, osteoproliferative, and biodegradable properties, PCL-based 3D scaffolds enriched with silver showed good potential for bone tissue engineering and offer a promising strategy as an ideal anti-adhesive and anti-biofilm tool for the reduction in prosthetic joints of infections caused by Candida spp. by using antimicrobial molecule-targeted delivery.

Abstract
Introduction Infection is one of the most distressing complications of total knee arthroplasty (TKA), requiring a long treatment process and may negatively affect patient satisfaction. All surgeons aim to achieve infection-free survival, painless, functional, and stable knee after treatment of periprosthetic joint infection (PJI) with two-stage revision treatment. Many factors play a role in determining clinical outcomes. We aimed to evaluate the factors influencing the clinical outcomes of patients undergoing two-stage revision knee arthroplasty for PJI. Methods Forty-nine patients were retrospectively evaluated. Forty-four patients met the inclusion criteria. Spacer types, growth rates in culture, types and amount of antibiotics added to the cement, and intervals between stages were evaluated. Pre- and post-treatment infection parameters, changes in the range of motion (ROM), clinical and functional (C&F) Knee Society Score (KSS) results, and complications were also studied. Results After a mean follow-up of 48.8 ± 16.5 months, re-infection was detected in five out of 44 patients (10.4%). No significant difference was noted regarding C&F KSS when comparing time intervals between the two stages, whether they were shorter or longer than 10 weeks. However, better ROM results were obtained in patients with less than 10 weeks between stages. The relationship between spacer type, ROM, and C&F KSS was not found to be significant. Particularly, the addition of 4g of teicoplanin to the cement shortened the time between the two stages. Conclusion C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels can be considered safe parameters for diagnosis, reimplantation timing, and follow-up. The use of dynamic spacers or reimplantation performed within 10 weeks after the first stage is associated with better ROM outcomes. Additionally, the addition of teicoplanin to the cement shortened the duration of antibiotic therapy.

Abstract
Introduction: Spinal Coccidioidomycosis, although rare, represents the most frequent osseous presentation of Coccidioides spp infection. The present review aims to describe the anatomical distribution, the epidemiological characteristics, and the diagnostic and therapeutic approach of this severe infection. Methods:A meticulous review of all published spinal Coccidioidomycosis cases was carried out. The studied population's demographics and the anatomical distribution of the infection were recorded. Furthermore, the medical and operative management as well as the disease outcome were studied. Results:Seventy-six cases (of which 78.9% males) with a mean age of 35.5 years were located. Regarding the anatomical distribution of the infection, the thoracic area was the most commonly affected spine region (26.3%). Among the studied patients, 14 (18.4%) were immunocompromised. Pain was the most commonly reported symptom (21.1%). Regarding the diagnostic approach of this infection, plain x-ray or CT scan indicated the disease in the majority of cases (44.7%). Pathology (48.7%), serology (42.1%) and microbiological examinations (35.5%) further established the firm diagnosis, with Coccidioides immitis being the most frequently isolated fungus. Medical management included mainly amphotericin B (in 57.9% of cases), followed by fluconazole (in 38.2% of cases). The disease required surgical intervention in the majority of cases (76.3%), while the infection had a successful outcome in 80.3% of cases. Conclusion:Spinal Coccidioidomycosis seems to require prolonged medical treatment, including proper antifungal therapy and, in most cases, operative management. Multidisciplinary approach, including infectious disease specialists, orthopaedic and/or spine surgeons, microbiologists and radiologists seems to be of utmost important for yielding favorable outcomes.

Abstract
Prosthetic joint infections (PJIs) caused by fungi, although relatively rare, represent a major surgery-related complication. An extremely rare fungal PJI, following revised total knee replacement (TKR) caused by Candida lusitaniae, is reported, and a meticulous review of similar cases is provided. A 74-year-old female, who underwent primary total knee arthroplasty 10 years ago and a revision surgery three weeks ago, presented with signs and symptoms of PJI. C. lusitaniae was eventually isolated from the periprosthetic tissue using the MALDI-TOF VitekMS–bioMérieux technique. Multiple strategies for managing this fungal PJI were performed, and finally, the patient was treated successfully with an intramedullary arthrodesis system and proper antifungal treatment, including fluconazole. A multidisciplinary approach is essential for the diagnosis and treatment of such severe infections. In persistent cases and in cases where revision surgery is extremely difficult to perform, arthrodesis seems to be an effective solution for the elimination of the infection. The efficacy of the therapeutic management of fungal PJIs remains unclear. Therefore, more research should be reported, focusing on proper treatment so that the optimal strategy in treating these severe infections may be established.

Abstract
The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre‐evaluation of the safety of microorganisms, intended for use in the food or feed chains, to support the work of EFSA's Scientific Panels. The QPS approach is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of relevant knowledge, safety concerns and occurrence of antimicrobial resistance. Safety concerns identified for a taxonomic unit (TU) are, where possible, confirmed at the species/strain or product level and reflected by ‘qualifications’. In the period covered by this statement, no new information was found that would change the status of previously recommended QPS TUs. Of the 50 microorganisms notified to EFSA in October 2021 to March 2022 (inclusive), 41 were not evaluated: 10 filamentous fungi, 1 Enterococcus faecium, 1 Clostridium butyricum, 3 Escherichia coli and 1 Streptomyces spp. because are excluded from QPS evaluation, and 25 TUs that have already a QPS status. Nine notifications, corresponding to seven TUs were evaluated: four of these, Streptococcus salivarius, Companilactobacillus formosensis, Pseudonocardia autotrophica and Papiliotrema terrestris, being evaluated for the first time. The other three, Microbacterium foliorum, Pseudomonas fluorescens and Ensifer adhaerens were re‐assessed. None of these TUs were recommended for QPS status: Ensifer adhaerens, Microbacterium foliorum, Companilactobacillus formosensis and Papiliotrema terrestris due to a limited body of knowledge, Streptococcus salivarius due to its ability to cause bacteraemia and systemic infection that results in a variety of morbidities, Pseudonocardia autotrophica due to lack of body of knowledge and uncertainty on the safety of biologically active compounds which can be produced, and Pseudomonas fluorescens due to possible safety concerns.

Abstract
Fungal prosthetic joint infections (PJIs), despite the fact that they are rare, represent a devastating complication. Such infections in revised knee arthroplasties pose a unique surgical and medical challenge. A rare case of Candida parapsilosis PJI in revised knee arthroplasty is reported. Furthermore, a thorough review of all published fungal PJIs cases in revised knee arthroplasties is provided. A 72-year-old female with total knee replacement surgery due to osteoarthritis 10 years ago, followed by two revision surgeries six and two years ago due to aseptic loosening, presented with signs and symptoms of septic loosening of the knee components. Resection arthroplasty and cement-spacer placement was performed and periprosthetic tissue cultures yielded Candida parapsilosis. The patient was commenced on proper antifungal treatment (AFT) for six months and then the second stage of the revision surgery was performed successfully. From 2000 to 2022, a total of 46 patients with median age 69 years [interquartile range (IQR = 10)], suffering fungal PJI occurring in revised knee arthroplasty have been reported. The median time from initial arthroplasty to symptoms’ onset was 12 months (IQR = 14). Cultures of local material (52.2%) and histology (6.5%) were the reported diagnostic method, while Candida species were the most commonly isolated fungi. Regarding surgical management, two-stage revision arthroplasty (TSRA) was performed in most cases (54.3%), with median time-interval of six months (IQR = 6) between the two stages. Regarding AFT, fluconazole was the preferred antifungal compound (78.3%), followed by voriconazole and amphotericin B (19.6% each). The median duration of AFT was five months (IQR = 4.5). Infection’s outcome was successful in 38 cases (82.6%). Fungal PJIs, especially in revised knee arthroplasties, are devastating complications. A combination of AFT and TSRA seems to be the treatment of choice. TSRA in these cases poses a special challenge, since major bone defects may be present. Therapeutic procedures remain unclear, thus additional research is needed.

[PMID: 35884133 PMCID: PMC9311527 DOI: 10.3390/antibiotics11070879] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 06/27/2022] [Accepted: 06/29/2022] [Indexed: 11/16/2022] Open
Abstract
Little is known about the clinical use of antifungal-loaded acrylic bone cement in the treatment of periprosthetic hip and knee joint infections (PJIs). Hence, we performed a literature search using PubMed/MEDLINE from inception until December 2021. Search terms were “cement” in combination with 13 antifungal agents. A total of 10 published reports were identified, which described 11 patients and 12 joints in which antifungal-loaded cement was employed. All studies were case reports or case series, and no randomized controlled trials were identified. In 6 of 11 patients, predisposing comorbidities regarding the emergence of a fungal PJI were present. The majority of the studies reported on infections caused by Candida species. In six cases (seven joints), the cement was solely impregnated with an antifungal, but no antibiotic agent (amphotericin B, voriconazole, and fluconazole). In the other five joints, the cement was impregnated with both antibiotic(s) and antifungals. Great discrepancies were seen regarding the exact loading dose. Four studies investigated the local elution of antifungal agents in the early postoperative period and observed a local release of antifungals in vivo. We conclude that there is a paucity of data pertaining to the clinical use of antifungal-loaded bone cement, and no studies have assessed the clinical efficacy of such procedures. Future studies are urgently required to evaluate this use of antifungals in PJI.

Abstract
Background: Coccidioidomycosis represents an endemic and challenging disease, with rare extrapulmonary manifestations. The present review of all published cases of core and extremities osseous coccidioidomycosis aims to describe epidemiology, patients’ characteristics, symptoms as well as medical and surgical treatment options and their effectiveness. Methods: A thorough review of all published skeletal core and extremity infections due to Coccidioides species was conducted. Information regarding demographics, causative fungus, antifungal treatment (AFT), surgical management as well as the infection outcome was recorded. Results: A total of 92 cases of Coccidioides spp. skeletal infections were recorded in 87 patients. The patients’ mean age was 35.3 years. The most common site of infection was the spine (82.6%), followed by the foot (6.5%), while the predominant symptom upon presentation was pain (29.9%). Immunosuppressive conditions and/or medications were observed in 21 patients (24.1%). Regarding imaging methods, indicating diagnosis, plain X-rays or CT scans were performed in most patients (50.6%), followed by magnetic resonance imaging (MRI) (47.1%). Most cases were diagnosed through histopathology (62; 71.3%), followed by serology testing (36; 42.4%) and by cultures (35; 40.2%). In 32 cases (36.8%), Coccidioides immitis was cultured, while in the remaining 55 cases (63.2%) the fungus was not further characterized. Regarding AFT, amphotericin B was the preferred agent (52.9%), followed by fluconazole (43.3%). In most cases (78.2%) surgical treatment was also performed. Treatment was successful in 80.5% of cases. Conclusions: Skeletal core and extremity infections due to Coccidioides spp. represent a severe disease. With the available data, the combination of prolonged proper AFT with surgical intervention seems to be the optimal current therapeutic approach.

Abstract
Background: Osteomyelitis caused by Aspergillus spp. is a severe, but rare, clinical entity. However, clear guidelines regarding the most effective medical management have not yet been established. The present study is a literature review of all such cases, in an effort to elucidate epidemiology, as well as the therapeutic management and the infection’s outcome. Methods: A thorough review of all reports of osteomyelitis of the appendicular and the axial skeleton, without the skull and the spine, caused by Aspergillus spp. was undertaken. Data about demographics, imaging techniques facilitating diagnosis, causative Aspergillus, method of mold isolation, antifungal treatment (AFT), surgical treatment, as well as the infection’s outcome were recorded and evaluated. Results: A total of 63 cases of osseous infection due to Aspergillus spp. were identified. The studied population’s mean age was 37.9 years. The most commonly affected site was the rib cage (36.8%). Most hosts suffered immunosuppressive conditions (76.2%). Regarding imaging methods indicating diagnosis, computer tomography (CT) was performed in most cases (42.9%), followed by plain X-ray (41.3%) and magnetic resonance imaging (MRI) (34.9%). The most frequent isolated mold was Aspergillus fumigatus (49.2%). Cultures and/or histopathology were used for definite diagnosis in all cases, while galactomannan antigen test was additionally used in seven cases (11.1%), polymerase chain reaction (PCR) in four cases (6.3%), and beta-d-glucan testing in three cases (4.8%). Regarding AFT, the preferred antifungal was voriconazole (61.9%). Most patients underwent surgical debridement (63.5%). The outcome was successful in 77.5%. Discussion: Osteomyelitis due to Aspergillus spp. represents a severe infection. The available data suggest that prolonged AFT in combination with surgical debridement is the preferred management of this infection, while identification of the responsible mold is of paramount importance.

Abstract
Background: Septic arthritis due to Aspergillus spp. represents a rare, but severe disease. Nevertheless, clear guidelines regarding most effective medical treatment have not yet been established. The present study is a literature review of all reported cases of fungal septic arthritis due to Aspergillus spp, in order to clarify epidemiology, as well as the medical and operative management and their outcome. Methods: A meticulous review of all published septic arthritis infections due to Aspergillus has been conducted. Information regarding demographics, causative fungus, antifungal treatment (AFT), surgical intervention, as well as the infection’s outcome were recorded and evaluated. Results: A total of 30 Aspergillus spp. strains from 29 hosts have been studied. The patients’ mean age was 45.8 years. The most commonly affected joint was the knee (45.7%), while the predominant symptom was joint pain (62%). Most patients were immunocompromised (72.4%). Diagnosis was established through cultures and/or histopathology. Aspergillus fumigatus was the most common responsible fungi (63.3%), followed by A. flavus (16.6%) and A. terreus (10%). Regarding AFT, the preferred agent proved to be Amphotericin B (14 cases; 48.3%), followed by voriconazole (11; 37.9%), while the mean AFT duration was 5.6 months. In most cases surgical treatment was also performed (in 4 cases no surgery was reported). Treatment was effective in 20 cases (69%). Conclusions: Septic arthritis caused by Aspergillus spp. represents a severe clinical entity. It seems that, with the available data, prolonged AFT along with surgical intervention is the preferred management of this infection, while identification of the responsible fungus is of utmost importance.

Abstract
Postoperative infections after arthroscopic anterior cruciate ligament (ACL) reconstruction (ACLR) represent a rare but severe complication. An extremely rare case of Aspergillus septic arthritis in a 27-year-old patient following arthroscopic ACLR is reported. The patient presented with signs of knee infection 14 days after ACLR. Two consecutive arthroscopic debridements were performed, while eventually histopathology, cultures and multiplex PCR test revealed Aspergillus identified as A. fumigatus by mass spectrometry. The patient commenced long-term treatment with voriconazole. Fungal arthritis or osteomyelitis following ACLR has a mild local and general inflammatory reaction when compared to the bacterial ones. Nevertheless, such infections may lead to aggressive osseous destruction and necrosis. A high index of suspicion is of utmost importance for early detection, while microscopic, histological examination and multiplex PCR may be more helpful for the diagnosis than cultures since cultures are more time-consuming and may vary depending on different factors.

Abstract
Background: Spondylodiscitis caused by Aspergillus spp. is a rare but life-threatening clinical entity. However, a consensus on diagnostic criteria and most effective medical management is still missing. The present study is a review of all published cases of spondylodiscitis caused by Aspergillus spp., in an effort to elucidate epidemiology, patients’ characteristics, andand the medical and surgical treatment options and their effectiveness. Methods: A thorough review of all existing spondylodiscitis cases caused by Aspergillus was performed. Data regarding demographics, responsible fungus, time between symptoms’ onset and firm diagnosis, antifungal treatment (AFT), surgical intervention, andand the infection’s outcome were investigated. Results: A total of 118 Aspergillus spondylodiscitis cases, yielding 119 Aspergillus spp. isolates, were identified in the literature. The patients’ mean age was 40.6 years. Magnetic resonance imaging (MRI) (after its introduction) indicated the diagnosis in most cases (66.7%), while definite diagnosis was established through cultures in the majority of cases (73.7%). Aspergillus fumigatus was isolated in most cases (73; 61.3%), followed by Aspergillus flavus (15; 12.6%) andand Aspergillus nidulans and terreus (7; 5.9%, each). The mean time between symptoms’ onset and diagnosis was 5.7 months. Amphotericin B was the preferred antifungal regiment (84 cases; 71.2%), followed by voriconazole (31; 26.3%), and the mean AFT duration was 6.1 months. The final outcome was successful in 93 cases (78.8%). Furthermore, 77 patients (65.3%) underwent surgery. Conclusions: Spondylodiscitis caused by Aspergillus spp. represents a clinical challenge, requiring a multidisciplinary approach. The present review has shown that prolonged AFT has been the standard of care of the studied cases, while surgical treatment seems to play an important role in selected patents.
