INTERNATIONAL ORTHOPAEDICS 2024; 48:5-20. [PMID: 37792014 PMCID: PMC10766661 DOI: 10.1007/s00264-023-05989-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 09/10/2023] [Indexed: 10/05/2023]
Abstract
OBJECTIVES Knowledge of Candida spondylodiscitis is limited to case reports and smaller case series. Controversy remains on the most effective diagnostical and therapeutical steps once Candida is suspected. This systematic review summarized all cases of Candida spondylodiscitis reported to date concerning baseline demographics, symptoms, treatment, and prognostic factors. METHODS A PRISMA-based search of PubMed, Web of Science, Embase, Scopus, and OVID Medline was performed from database inception to November 30, 2022. Reported cases of Candida spondylodiscitis were included regardless of Candida strain or spinal levels involved. Based on these criteria, 656 studies were analyzed and 72 included for analysis. Kaplan-Meier curves, Fisher's exact, and Wilcoxon's rank sum tests were performed. RESULTS In total, 89 patients (67% males) treated for Candida spondylodiscitis were included. Median age was 61 years, 23% were immunocompromised, and 15% IV drug users. Median length of antifungal treatment was six months, and fluconazole (68%) most commonly used. Thirteen percent underwent debridement, 34% discectomy with and 21% without additional instrumentation. Median follow-up was 12 months. The two year survivorship free of death was 80%. The two year survivorship free of revision was 94%. Younger age (p = 0.042) and longer length of antifungal treatment (p = 0.061) were predictive of survival. CONCLUSION Most patients affected by Candida spondylodiscitis were males in their sixties, with one in four being immunocompromised. While one in five patients died within two years of diagnosis, younger age and prolonged antifungal treatment might play a protective role.

Abstract
Antimicrobial resistance is a matter of rising concern, especially in fungal diseases. Multiple reports all over the world are highlighting a worrisome increase in azole- and echinocandin-resistance among fungal pathogens, especially in Candida species, as reported in the recently published fungal pathogens priority list made by WHO. Despite continuous efforts and advances in infection control, development of new antifungal molecules, and research on molecular mechanisms of antifungal resistance made by the scientific community, trends in invasive fungal diseases and associated antifungal resistance are on the rise, hindering therapeutic options and clinical cures. In this context, in vitro susceptibility testing aimed at evaluating minimum inhibitory concentrations, is still a milestone in the management of fungal diseases. However, such testing is not the only type at a microbiologist's disposal. There are other adjunctive in vitro tests aimed at evaluating fungicidal activity of antifungal molecules and also exploring tolerance to antifungals. This plethora of in vitro tests are still left behind and performed only for research purposes, but their role in the context of invasive fungal diseases associated with antifungal resistance might add resourceful information to the clinical management of patients. The aim of this review was therefore to revise and explore all other in vitro tests that could be potentially implemented in current clinical practice in resistant and difficult-to-treat cases.

Abstract
Background Osteomyelitis due to Candida krusei are extremely rare, given that only six cases have been reported, all of which are limited to the patients with immunocompromising risk factors. Here we report a case of C. krusei osteomyelitis in an immunocompetent patient, presenting with multiple huge cystic lesions of talus. Case presentation A 66-year-old female presented with one year history of painful swelling of right ankle and a draining sinus around lateral malleolus. Five months and three months ago, she had undergone arthroscopic synovectomy and bursectomy which revealed no causative organism. Open bursectomy with sinus tract excision was performed and intravenous antibiotic was administered. Two year after the surgery, the patient revisited the clinic for recurrent painful swelling with pus drainage at the same location. Multiple huge cystic lesions with osteolysis and sclerotic rim of talus were found and C. krusei was isolated from tissue culture. The patient received surgical debridement and prolonged antifungal treatment comprising caspofungin and voriconazole. Conclusions In this case, C. krusei infection showed atypically aggressive osteolysis shown as multiple huge cystic abscess. High index of suspicion is critical for early diagnosis and treatment to prevent such devastating results even in an immunocompetent patient.

Abstract
Although Candida albicans remains the main cause of candidiasis, in recent years a significant number of infections has been attributed to non-albicans Candida (NAC) species, including Candida krusei. This epidemiological change can be partly explained by the increased resistance of NAC species to antifungal drugs. C. krusei is a diploid, dimorphic ascomycetous yeast that inhabits the mucosal membrane of healthy individuals. However, this yeast can cause life-threatening infections in immunocompromised patients, with hematologic malignancy patients and those using prolonged azole prophylaxis being at higher risk. Fungal infections are usually treated with five major classes of antifungal agents which include azoles, echinocandins, polyenes, allylamines, and nucleoside analogues. Fluconazole, an azole, is the most commonly used antifungal drug due to its low host toxicity, high water solubility, and high bioavailability. However, C. krusei possesses intrinsic resistance to this drug while also rapidly developing acquired resistance to other antifungal drugs. The mechanisms of antifungal resistance of this yeast involve the alteration and overexpression of drug target, reduction in intracellular drug concentration and development of a bypass pathway. Antifungal resistance menace coupled with the paucity of the antifungal arsenal as well as challenges involved in antifungal drug development, partly due to the eukaryotic nature of both fungi and humans, have left researchers to exploit alternative therapies. Here we briefly review our current knowledge of the biology, pathophysiology and epidemiology of a potential multidrug-resistant fungal pathogen, C. krusei, while also discussing the mechanisms of drug resistance of Candida species and alternative therapeutic approaches.

Abstract
Introduction: Candida species have been regarded as global health threats due to their ability to cause invasive infections. It is challenging to treat Candida bloodstream infections, which are associated with high mortality levels. Monotherapy with antifungals is sometimes not effective against severe Candida infections, and combination therapy is needed in clinical practice.Areas covered: This review was undertaken based on data from a PubMed search for English language reports published before March 2021 by using the terms 'caspofungin,' 'Candida species,' 'combination therapy,' 'antifungal effect,' and 'novel antifungal agent.'Expert opinion: Combination therapy is an empirical strategy for treating refractory Candida infections. Caspofungin has been recommended to treat candidaemia. Caspofungin in combination therapy has some applications, while the efficacy of combination therapy in the treatment of refractory Candida infections needs more study, such as randomized controlled trials. In addition, novel compounds or drugs with potential antifungal activities have been examined, and some of them exhibit synergistic interactions with caspofungin. Thus, the antifungal activity of caspofungin in combination with antifungals or non-antifungals against Candida species in vitro and in clinical therapy is summarized.

Abstract
While the incidence of spondylodiscitis is rising because of longer life expectancy and the increasing use of immunosuppressant drug, indwelling devices and spinal surgeries, the fungal aetiology remains rare, sometimes affecting intravenous drug users. Candida spondylodiscitis is an extremely rare complication post aortic aneurysm repair. It is potentially fatal due to the risk of aneurysm rupture and septic complications. The growing problem of systemic diseases caused by Candida species reflects the enormous increase of patients at risk. The treatment of this complicated entity is challenging and often requiring a multidisciplinary team. We reported the rare case of Candida spondylodiscitis contiguous to infected aortic aneurysm in a 74-year-old male intravenous drug user, to the extent which the vertebral body bony destruction progressed to need one-stage posterior and anterior spinal fusion surgery with curettage. Our surgical intervention combined with prolonged course of antifungal therapy could successfully eradicate the infection and resolve the neurological deficits.

Abstract
Background Invasive infections with Candida krusei are uncommon and rarely complicated by spondylitis. Previous described cases were solely treated with antimycotic therapy, despite guidelines recommending surgical interventions. Case presentation We describe a case of C. krusei spondylitis in a patient treated with chemotherapy for acute myeloid leukemia. After induction chemotherapy, the patient developed a candidemia, which was treated with micafungin. One month after the candidemia, the patient was admitted with severe lumbar pain. Spondylitis of the L4 and L5 vertebra was diagnosed on MR-imaging, with signs suggesting an atypical infection. The patient was treated with anidulafungin combined with voriconazole. Despite maximal conservative management symptoms gradually worsened eventually requiring surgical intervention. Conclusions In contrast to previous case reports, antimycotic treatment alone could be insufficient in treating C. krusei spondylitis.

Abstract
To report a rare case of fungal spondylodiscitis in a patient recovered from H7N9 virus infection and perform a literature review of the different characteristics of Candida and Aspergillus spondylodiscitis, we reviewed cases of spondylodiscitis caused by Candida and Aspergillus species. Data, including patients' information, pathogenic species, treatment strategy, outcomes, and relapses, were collected and summarized. The characteristics of Candida and Aspergillus spondylodiscitis were compared to see if any differences in clinical features, management, or consequences could be detected. The subject of the case study was first misdiagnosed as having a vertebral tumor, and then, following open biopsy, was diagnosed as having fungal spondylodiscitis. The patient made a good recovery following radical debridement. Seventy-seven additional cases of Candida spondylodiscitis and 94 cases of Aspergillus spondylodiscitis were identified in the literature. Patients with Candida spondylodiscitis tended to have a better outcome than patients with Aspergillus spondylodiscitis (cure rate 92.3% vs. 70.2%). Candida was found more frequently (47.8%) than Aspergillus (26.7%) in blood cultures, while neurological deficits were observed more often in patients with Aspergillus spondylodiscitis (43.6% vs. 25.6%). Candida spinal infections were more often treated by radical debridement (60.5% vs. 39.6%). Patients with Candida spondylodiscitis have better outcomes, which may be associated with prompt recognition, radical surgical debridement, and azoles therapy. A good outcome can be expected in fungal spondylodiscitis with appropriate operations and anti-fungal drugs.

Abstract
Yeasts have a tradition in biotechnological applications, and Saccharomyces species are the most dominating representatives. Among the yeast species, Candida krusei has been isolated from different habitats, and in recent years, it has gained increased interest because of its diverse biotechnological role. It is found in many fermented food items and dairy products and has also been exploited for production of biochemicals and enzymes. However, because of its opportunistic pathogenic nature, it draws scientific attention regarding the safety of its industrial exploitation. Candida krusei generally causes infections in immunocompromised patients, such as those suffering from Human immunodeficiency virus - acquired immune deficiency syndrome, and also in cancer patients. The recent increase in the use of immunosuppressive drugs has increased the chances of C. krusei infections. Candida krusei possesses an intrinsic resistance to many triazole antifungal drugs, especially fluconazole, which is a main drug used in antifungal therapy; therefore, there is serious concern regarding its safe industrial use.

Abstract
Spondylodiscitis is an inflammatory disease, usually infectious, of one or more vertebral bodies and of corresponding intervertebral discs. The fungal aetiology is rare (less than 5% of cases), affecting mostly immunocompromised individuals. It is often a delayed diagnosis by the indolence of symptoms, presenting itself as a serious infection, which may result in important functional consequences. The authors present the case of a 75-year-old male, with constitutional complaints and intense back pain. Prior recent history of left hemicolectomy due to diverticulitis with multiple surgical complications, resulted in prolonged intensive care unit hospitalisation, and, later on, an episode of fungal endophthalmitis. The diagnosis of spondylodiscitis L5/S1 was performed by MRI. The patient underwent surgical disco-vertebral debridement and isolation of a Candida albicans was seen in the collected surgical material. No evidence of an immunossupressive status was found. Treatment was complemented with liposomal amphotericin B in the maximum recommended dose.

Abstract
BACKGROUND CONTEXT Discitis or epidural abscess after discogram is a rare but known complication. It is more commonly bacterial; however, fungal discitis has been previously reported in immunocompromised patients. The management of fungal discitis in immunocompetent patients is rarely presented or addressed in the literature. PURPOSE To present a rare atypical fungal discitis after routine discogram with a typical presentation in an immunocompetent host, review diagnostic and management guidelines for discitis, and provide recommendations for management of atypical discitis in immunocompetent patients. STUDY DESIGN Case report and review of the literature. METHODS A 40-year-old woman presented with a 3-week history of progressively worsening low back pain after a lumbar discogram. Magnetic resonance imaging revealed L3-L4 discitis without an epidural abscess. Left L3 and L4 hemilaminectomies with L3-L4 discectomy were performed. An inflammatory mass was seen in the L3-L4 disc space region extending to the left L3 foramen. RESULTS Culture specimens obtained during surgery from both the disc and epidural space speciated to Candida lusitaniae. The patient completed a 6-month course of fluconazole therapy. At 2-year follow-up, she continued to be asymptomatic, without any recurrence of infection or neurologic sequelae. CONCLUSIONS We report a case of C. lusitaniae spondylodiscitis after discography in an immunocompetent patient with long-term follow-up. Clinicians must maintain a high index of suspicion for discitis in patients who undergo this procedure. If discitis is suspected, culture specimens must be evaluated for fungal and mycobacterial organisms, even in the immunocompetent host. With proper surveillance, surgical intervention, and appropriate postoperative follow-up, this complication can be effectively managed with excellent long-term outcome.

Abstract
Candidal vertebral osteomyelitis represents an extremely rare invasive mycosis and can be difficult to treat due to poor drug penetration into bony tissue. We report on a case of vertebral osteomyelitis caused by Candida krusei in a patient who had neutropenia as a result of chemotherapy for acute myelogenous leukaemia. The patient received prophylactic liposomal amphotericin B during chemotherapy but became febrile and experienced severe lumbar pain. Magnetic resonance imaging revealed vertebral osteochondrosis. C. krusei was recovered from blood cultures and voriconazole monotherapy was initiated but proved unsuccessful. The patient was then started on caspofungin monotherapy, which was discontinued after Candida krusei was no longer recoverable from blood cultures. However, as lumbar pain increased and spinal biopsy confirmed the presence of Candida krusei, caspofungin therapy was resumed. Oral posaconazole was added to the regimen when the patient did not improve after 30 days of caspofungin therapy. Combined antimycotic therapy resulted in a successful outcome.

Abstract
Candida krusei is well known as a fungal pathogen for patients with hematologic malignancies and for transplant recipients. Using the ARTEMIS Antifungal Surveillance Program database, we describe geographic and temporal trends in the isolation of C. krusei from clinical specimens and the in vitro susceptibilities of 3,448 isolates to voriconazole as determined by CLSI (formerly NCCLS) disk diffusion testing. In addition, we report the in vitro susceptibilities of bloodstream infection isolates of C. krusei to amphotericin B (304 isolates), flucytosine (254 isolates), anidulafungin (121 isolates), caspofungin (300 isolates), and micafungin (102 isolates) as determined by CLSI broth microdilution methods. Geographic differences in isolation were apparent; the highest frequency of isolation was seen for the Czech Republic (7.6%) and the lowest for Indonesia, South Korea, and Thailand (0 to 0.3%). Overall, 83% of isolates were susceptible to voriconazole, ranging from 74.8% in Latin America to 92.3% in North America. C. krusei was most commonly isolated from hematology-oncology services, where only 76.7% of isolates were susceptible to voriconazole. There was no evidence of increasing resistance of C. krusei to voriconazole from 2001 to 2005. Decreased susceptibilities to amphotericin B (MIC at which 90% of isolates were inhibited [MIC(90)], 4 microg/ml) and flucytosine (MIC(90), 16 microg/ml) were noted, whereas 100% of isolates were inhibited by < or =2 microg/ml of anidulafungin (MIC(90), 0.06 microg/ml), micafungin (MIC(90), 0.12 microg/ml) or caspofungin (MIC(90), 0.25 microg/ml). C. krusei is an uncommon but multidrug-resistant fungal pathogen. Among the systemically active antifungal agents, the echinocandins appear to be the most active against this important pathogen.
