Clinical Characteristics, Prognosis Factors and Metagenomic Next-Generation Sequencing Diagnosis of Mucormycosis in patients With Hematologic Diseases.

INTRODUCTION: New diagnostic methods and antifungal strategies may improve prognosis of mucormycosis. We describe the diagnostic value of metagenomic next⁃generation sequencing (mNGS) and identify the prognostic factors of mucormycosis. METHODS: We conducted a retrospective study of hematologic patients suffered from mucormycosis and treated with monotherapy [amphotericin B (AmB) or posaconazole] or combination therapy (AmB and posaconazole). The primary outcome was 84-day all-cause mortality after diagnosis. RESULTS: Ninety-five patients were included, with "proven" (n = 27), "probable" (n = 16) mucormycosis confirmed by traditional diagnostic methods, and "possible" (n = 52) mucormycosis with positive mNGS results. The mortality rate at 84 days was 44.2%. Possible + mNGS patients and probable patients had similar diagnosis processes, overall survival rates (44.2% vs 50.0%, p = 0.685) and overall response rates to effective drugs (44.0% vs 37.5%, p = 0.647). Furthermore, the median diagnostic time was shorter in possible + mNGS patients than proven and probable patients (14 vs 26 days, p < 0.001). Combination therapy was associated with better survival compared to monotherapy at six weeks after treatment (78.8% vs 53.1%, p = 0.0075). Multivariate analysis showed that combination therapy was the protective factor (HR = 0.338, 95% CI: 0.162-0.703, p = 0.004), though diabetes (HR = 3.864, 95% CI: 1.897-7.874, p < 0.001) and hypoxemia (HR = 3.536, 95% CI: 1.874-6.673, p < 0.001) were risk factors for mortality. CONCLUSIONS: Mucormycosis is a life-threatening infection. Early management of diabetes and hypoxemia may improve the prognosis. Exploring effective diagnostic and treatment methods is important, and combination antifungal therapy seems to hold potential benefits.

Treatments for pathogen infection rescued 2 patients with renal artery rupture after kidney transplantation: A case report.

RATIONALE: Renal artery rupture due to allograft infection, especially by fungi, is a serious clinical complication that can occur after kidney transplantation, and may lead to graft loss and death. PATIENT CONCERNS: Two kidney recipients from China who developed renal artery rupture at our hospital on 5 days (47-year-old female) and 45 days (39-year-old male) after surgery. DIAGNOSES: The male had immunoglobulin A nephropathy as a primary disease, and experienced a postoperative attack of vascular rejection and mixed infection by Mucor and bacteria. The female had chronic glomerulonephritis as a primary disease, and experienced renal artery rupture near the anastomosis site with infection by fungi and other pathogens. INTERVENTIONS: The male received resection of the implanted kidney and antibiotic therapy with intravenous vancomycin (0.5 g, 2 days) and amphotericin B (530 mg in 33 days). The female received replacing the segment of renal arterial and internal iliac artery by saphenous vein, as well as antibiotic therapy with amphotericin B (320 mg in 8 days). OUTCOMES: The male was recovered and received a second transplantation, while the female was discharged on postoperative day 19. LESSONS: In both patients, prompt surgery and aggressive treatment with an antifungal drug (amphotericin B) and antidrugs led to successful rescue.

Mucormicosis: un dulce enemigo, serie de casos.

La mucormicosis es una infección fúngica poco frecuente causada por hongos del orden Mucorales, la cual se presenta en individuos inmunocomprometidos o con pérdida de la integridad de la barrera de piel o mucosas. Se reportan cuatro casos de mucormicosis rinocerebral atendidos en un hospital de tercer nivel de Cali (Colombia) durante un periodo de tres años. Los cuatro pacientes presentaron diferentes cuadros clínicos y tiempos de evolución. Todos tenían diagnóstico de diabetes mellitus de tipo 2, de novo o previo, con una hemoglobina glucosilada de ingreso mayor del 10 % y en todos se descartaron otras enfermedades que explicaran su compromiso inmunitario. La mucormicosis se diagnosticó por la visualización directa de hifas hialinas sincitiales (coenocytic) en las biopsias tomadas. El pilar del tratamiento fue la anfotericina B liposómica junto con el desbridamiento quirúrgico. Dos pacientes presentaron coinfección bacteriana. De los cuatro, uno firmó su egreso voluntario sin completar el tratamiento y otro falleció. Los dos pacientes restantes han asistido a los controles y han mostrado una adecuada evolución.

Novel combinatorial approach: Harnessing HIV protease inhibitors to enhance amphotericin B's antifungal efficacy in cryptococcosis.

Cryptococcosis is a fungal infection that is becoming increasingly prevalent worldwide, particularly among individuals with compromised immune systems, such as HIV patients. Amphotericin B (AmB) is the first-line treatment mainly combined with flucytosine. The scarcity and the prohibitive cost of this regimen urge the use of fluconazole as an alternative, leading to increased rates of treatment failure and relapses. Therefore, there is a critical need for efficient and cost-effective therapy to enhance the efficacy of AmB. In this study, we evaluated the efficacy of the HIV protease inhibitors (PIs) to synergize the activity of AmB in the treatment of cryptococcosis. Five PIs (ritonavir, atazanavir, saquinavir, lopinavir, and nelfinavir) were found to synergistically potentiate the killing activity of AmB against Cryptococcus strains with Æ©FICI ranging between 0.09 and 0.5 against 20 clinical isolates. This synergistic activity was further confirmed in a time-kill assay, where different AmB/PIs combinations exhibited fungicidal activity within 24 hrs. Additionally, PIs in combination with AmB exhibited an extended post-antifungal effect on treated cryptococcal cells for approximately 10 hrs compared to 4 hours with AmB alone. This promising activity against cryptococcal cells did not exhibit increased cytotoxicity towards treated kidney cells, ruling out the risk of drug combination-induced nephrotoxicity. Finally, we evaluated the efficacy of AmB/PIs combinations in the Caenorhabditis elegans model of cryptococcosis, where these combinations significantly reduced the fungal burden of the treated nematodes by approximately 2.44 Log10 CFU (92.4%) compared to the untreated worms and 1.40 Log10 ((39.4%) compared to AmB alone. The cost-effectiveness and accessibility of PIs in resource-limited geographical areas compared to other antifungal agents, such as flucytosine, make them an appealing choice for combination therapy.

Mechanism of azole resistance in Candida vulturna, an emerging multidrug resistant pathogen related with Candida haeumulonii and Candida auris.

BACKGROUND: Candida vulturna is an emerging pathogen belonging to the Metshnikowiaceae family together with Candida auris and Candida haemulonii species complex. Some strains of this species were reported to be resistant to several antifungal agents. OBJECTIVES: This study aims to address identification difficulties, evaluate antiungal susceptibilities and explore the molecular mechanisms of azole resistance of Candida vulturna. METHODS: We studied five C. vulturna clinical strains isolated in three Colombian cities. Identification was performed by phenotypical, proteomic and molecular methods. Antifungal susceptibility testing was performed following CLSI protocol. Its ERG11 genes were sequenced and a substitution was encountered in azole resistant isolates. To confirm the role of this substitution in the resistance phenotype, Saccharomyces cerevisiae strains with a chimeric ERG11 gene were created. RESULTS: Discrepancies in identification methods are highlighted. Sequencing confirmed the identification as C. vulturna. Antifungal susceptibility varied among strains, with four strains exhibiting reduced susceptibility to azoles and amphotericin B. ERG11 sequencing showed a point mutation (producing a P135S substitution) that was associated with the azole-resistant phenotype. CONCLUSIONS: This study contributes to the understanding of C. vulturna's identification challenges, its susceptibility patterns, and sheds light on its molecular mechanisms of azole resistance.

American Cutaneous Leishmaniasis: Imported cases in Berlin 2000-2023.

BACKGROUND: American Cutaneous Leishmaniasis (ACL) shows variable response to therapy, but data on species-specific treatment efficacy is scarce. We describe the clinical characteristics and outcome of patients with ACL imported to a tertiary centre in Germany and determine whether species-specific therapy according to the 2014 "LeishMan" group recommendations is associated with cure. METHODS: A retrospective chart review was conducted at the Charité Institute of International Health in Berlin. We analysed data on PCR-confirmed ACL cases collected between 2000 and 2023. Systemic therapy included liposomal amphotericin B, miltefosine, pentavalent antimony, ketoconazole or itraconazole. Localized therapy included perilesional pentavalent antimony or paromomycin ointment. Cure was defined as re-epithelialization of ulcers or disappearance of papular-nodular lesions after 3 months of treatment. Logistic regression models were used to quantify the effect of species-specific systemic therapy on the outcome. RESULTS: 75 cases were analysed. Most patients were male (62%), median age was 35 years, no patient had a history of immunosuppression. The most common reason for travel was tourism (60%), the most common destination was Costa Rica (28%), the median duration of illness was 8 weeks, and most patients presented with ulcers (87%). Lesions were complex in 43%. The most common Leishmania (L.) species was L. braziliensis (28%), followed by L. panamensis (21%). 51/73 (70%) patients were cured after initial therapy and 17/21 (81%) after secondary therapy. Cure after systemic therapy was more frequent when species-specific treatment recommendations were followed (33/45; 73%), compared to when not followed, (6/17; 35%, P = 0.008). This association was independent of age, sex, previous therapy, complex lesions, and Leishmania species (adjusted OR, 5.06; 95% CI, 1.22-24.16). CONCLUSIONS: ACL is a rare, imported disease in Germany. Complex lesions were common, challenging successful therapy. This study highlights the importance of identifying the parasite species and suggests that a species-specific approach to treatment leads to better outcomes.

Propensity of Candida spp. prosthetic joint infection clinical isolates to form aggregates in synovial fluid and the clinical ramifications.

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.

Resistant C. albicans implicated in recurrent vulvovaginal candidiasis (RVVC) among women in a tertiary healthcare facility in Kumasi, Ghana.

BACKGROUND: Vulvovaginal candidiasis is a common fungal infection that affects the female lower genital tract. This study determined the major risk factors associated with vulvovaginal infection (VVI) in the Ashanti region of Ghana and also determined the antifungal resistance patterns of Candida albicans isolates to some antifungals. METHODS: Three hundred and fifty (350) high vaginal swab (HVS) samples were collected from women who presented with signs and symptoms of VVI. A structured questionnaire was administered to one hundred and seventy-two (172) of the women. HVS samples were cultured on Sabouraud dextrose agar with 2% chloramphenicol. The polymerase chain reaction was employed to confirm C. albicans. Antifungal susceptibility testing was performed and the susceptibility of C. albicans isolates to fluconazole, clotrimazole, amphotericin B, nystatin, miconazole and 5-flurocytosine were assessed. RESULTS: Vaginal infection was most prevalent amongst females in their reproductive age (21 to 30 years; 63.0%). The study found a significant association between vaginal infections and some risk factors such as sexual practices (p < 0.001), antibiotic misuse (p < 0.05), poor personal hygiene (p < 0.005) and birth control methods (p < 0.049). Out of the 350 HVS samples collected, 112 yielded yeast cells with 65 (58%) identified as C. albicans. The C. albicans isolates were resistant to 5' flucytosine (100%), fluconazole (70%), voriconazole (69.2%), miconazole (58.5%) and nystatin (49.2%). C. albicans isolates were more susceptible to amphotericin B (53.8%) and clotrimazole (45.1%), although an appreciable number of isolates showed resistance (46.1% and 52.3%, respectively). CONCLUSION: There should be nationwide education on all associated risk factors of VVI. Also, use of the various antifungal agents in vaginal candidiasis should proceed after antifungal susceptibility testing to ensure efficacious use of these agents.

Sterol 14-alpha demethylase (CYP51) activity in Leishmania donovani is likely dependent upon cytochrome P450 reductase 1.

Liposomal amphotericin B is an important frontline drug for the treatment of visceral leishmaniasis, a neglected disease of poverty. The mechanism of action of amphotericin B (AmB) is thought to involve interaction with ergosterol and other ergostane sterols, resulting in disruption of the integrity and key functions of the plasma membrane. Emergence of clinically refractory isolates of Leishmania donovani and L. infantum is an ongoing issue and knowledge of potential resistance mechanisms can help to alleviate this problem. Here we report the characterisation of four independently selected L. donovani clones that are resistant to AmB. Whole genome sequencing revealed that in three of the moderately resistant clones, resistance was due solely to the deletion of a gene encoding C24-sterol methyltransferase (SMT1). The fourth, hyper-resistant resistant clone (>60-fold) was found to have a 24 bp deletion in both alleles of a gene encoding a putative cytochrome P450 reductase (P450R1). Metabolic profiling indicated these parasites were virtually devoid of ergosterol (0.2% versus 18% of total sterols in wild-type) and had a marked accumulation of 14-methylfecosterol (75% versus 0.1% of total sterols in wild-type) and other 14-alpha methylcholestanes. These are substrates for sterol 14-alpha demethylase (CYP51) suggesting that this enzyme may be a bona fide P450R specifically involved in electron transfer from NADPH to CYP51 during catalysis. Deletion of P450R1 in wild-type cells phenocopied the metabolic changes observed in our AmB hyper-resistant clone as well as in CYP51 nulls. Likewise, addition of a wild type P450R1 gene restored sterol profiles to wild type. Our studies indicate that P450R1 is essential for L. donovani amastigote viability, thus loss of this gene is unlikely to be a driver of clinical resistance. Nevertheless, investigating the mechanisms underpinning AmB resistance in these cells provided insights that refine our understanding of the L. donovani sterol biosynthetic pathway.

Aneuploidy underlies brefeldin A-induced antifungal drug resistance in Cryptococcus neoformans.

Cryptococcus neoformans is at the top of the list of "most wanted" human pathogens. Only three classes of antifungal drugs are available for the treatment of cryptococcosis. Studies on antifungal resistance mechanisms are limited to the investigation of how a particular antifungal drug induces resistance to a particular drug, and the impact of stresses other than antifungals on the development of antifungal resistance and even cross-resistance is largely unexplored. The endoplasmic reticulum (ER) is a ubiquitous subcellular organelle of eukaryotic cells. Brefeldin A (BFA) is a widely used chemical inducer of ER stress. Here, we found that both weak and strong selection by BFA caused aneuploidy formation in C. neoformans, mainly disomy of chromosome 1, chromosome 3, and chromosome 7. Disomy of chromosome 1 conferred cross-resistance to two classes of antifungal drugs: fluconazole and 5-flucytosine, as well as hypersensitivity to amphotericin B. However, drug resistance was unstable, due to the intrinsic instability of aneuploidy. We found overexpression of AFR1 on Chr1 and GEA2 on Chr3 phenocopied BFA resistance conferred by chromosome disomy. Overexpression of AFR1 also caused resistance to fluconazole and hypersensitivity to amphotericin B. Furthermore, a strain with a deletion of AFR1 failed to form chromosome 1 disomy upon BFA treatment. Transcriptome analysis indicated that chromosome 1 disomy simultaneously upregulated AFR1, ERG11, and other efflux and ERG genes. Thus, we posit that BFA has the potential to drive the rapid development of drug resistance and even cross-resistance in C. neoformans, with genome plasticity as the accomplice.

Cutaneous mucormycosis infection owing to Rhizomucor variabilis presenting as recurrent lower limb ulceration and cellulitis in a diabetic patient.

Primary cutaneous mucormycosis is caused by environmental fungi and may complicate leg ulcers or traumatic wounds even in immunocompetent individuals. This case report highlights recurrent lower limb ulcers and cellulitis in a patient with type two diabetes mellitus, which was unresponsive to conventional antibiotic treatment. Histopathology revealed the diagnosis of cutaneous mucormycosis, and fungal cultures identified Rhizopus variabilis as the causative organism. Initial courses of oral azole antifungals yielded only partial response and he eventually required more aggressive treatment with i.v. amphotericin B and oral posaconazole. Good treatment outcomes for this condition require a high index of clinical suspicion, early histopathological and microbiological diagnosis, targeted systemic antifungal therapy, and surgical debridement if necessary.

Concanavalin A, lectin from Canavalia ensiformis seeds has Leishmania infantum antipromastigote activity mediated by carbohydrate recognition domain.

Leishmaniases, caused by Leishmania parasites, are widespread and pose significant health risks globally. Visceral leishmaniasis (VL) is particularly prevalent in Brazil, with high morbidity and mortality rates. Traditional treatments, such as pentavalent antimonials, have limitations due to toxicity and resistance. Therefore, exploring new compounds like lectins is crucial. Concanavalin A (ConA) has shown promise in inhibiting Leishmania growth. This study aimed to evaluate its leishmanicidal effect on L. infantum promastigotes and understand its mechanism of action. In vitro tests demonstrated inhibition of promastigote growth when treated with ConA, with IC50 values ranging from 3 to 5 µM over 24-72 h. This study suggests that ConA interacts with L. infantum glycans. Additionally, ConA caused damage to the membrane integrity of parasites and induced ROS production, contributing to parasite death. Scanning electron microscopy confirmed morphological alterations in treated promastigotes. ConA combined with the amphotericin B (AmB) showed synergistic effects, reducing the required dose of AmB, and potentially mitigating its toxicity. ConA demonstrated no cytotoxic effects on macrophages, instead stimulating their proliferation. These findings reinforce that lectin exhibits promising leishmanicidal activity against L. infantum promastigotes, making ConA a potential candidate for leishmaniasis treatment.

Association between the hypokalaemia index based on area over the serum potassium concentration curve and occurrence of acute kidney injury in patients administered liposomal amphotericin B.

BACKGROUND: Acute kidney injury (AKI) and hypokalaemia are common adverse events after treatment with liposomal amphotericin B (L-AMB). OBJECTIVES: Because excess potassium (K) leakage occurs during renal tubular injury caused by L-AMB, measuring the decrease in rate of serum K concentration might be more useful to assess the renal impact of L-AMB than hypokalaemia identified from a one-point measurement. The effects of a decrease in K concentration and duration of hypokalaemia on AKI were investigated. METHODS: A ≥ 10% decrease in K concentration from the reference concentration within a 7-day timeframe was evaluated. The hypokalaemia index, which combines the duration of K concentration lower than the reference and a marked low K concentration, was calculated from the area over the concentration curve. RESULTS: Eighty-six patients were included in the study. The incidences of AKI and decrease in K concentration were 36.0% and 63.9%, respectively. Of patients who developed both adverse events, a decrease in K concentration occurred first in 22 of 26 patients, followed by AKI 7 days later. Hypokalaemia did not increase AKI risk whereas a decrease in K concentration was an independent risk factor for AKI. The hypokalaemia index in patients with AKI was significantly higher than those without AKI (5.35 vs. 2.50 points, p = 0.002), and ≥3.45 points was a significant predictor for AKI. CONCLUSION: A ≥ 10% decrease in the K concentration was a significant factor for AKI in patients receiving L-AMB therapy. In such patients, dose reduction or alternative antifungals could be considered based on the hypokalaemia index.

A cost-effectiveness analysis of the use of oral ibrexafungerp versus fluconazole for acute vulvovaginal candidiasis in the UK NHS primary care service.

BACKGROUND: Vulvovaginal Candidiasis (VVC) is a fungal infection causing inflammation of the vagina and/or the vulva. Symptoms include itching, irritation, and discharge. VVC presents commonly across primary care and, despite its mild symptoms, carries psychological burden and has a significant impact on women's quality of life. UK guidelines support treatment via oral or topical azole antifungal agents. Recent evidence attests to the superiority of novel non-azole antifungals. Thus, rigorous financial assessment of both antifungals is necessary for optimal VVC treatment allocation in UK primary care. AIM: To evaluate the cost-effectiveness of ibrexafungerp against the gold standard fluconazole as first-line treatment of VVC within the NHS. METHOD: A systematic review on the efficacy of ibrexafungerp and fluconazole in acute VVC was conducted. Cost-effectiveness analysis was initiated using health outcome data from the DOVE trial, a Phase 2 RCT. Costs in pound sterling were ascertained in monetary units, and effectiveness determined as reduced need for follow-up medication. RESULTS: An incremental cost-effectiveness ratio of £2185.74 was determined. This suggests oral ibrexafungerp being largely more costly yet slightly more effective than fluconazole, and thus has unfavourable net benefit. Two sensitivity analyses were conducted considering follow-up medication combination and market price, which provided confidence in the calculated cost-effectiveness ratio. CONCLUSION: This analysis highlights fluconazole's cost-effectiveness in current UK guidelines and favourability.

Hepatoprotective effect of diammonium glycyrrhizinate and neuroprotective effect of piperazine ferulate on AmB-induced liver and kidney injury by suppressing apoptosis in vitro and in vivo.

Amphotericin B (AmB) induced liver and kidney injury is often responsible for hepatic and renal dysfunction. Therefore, the protection strategy on liver and renal functions in patients treated with AmB should be emphasized. In this paper, diammonium glycyrrhizinate (DG) and piperazine ferulate (PF) were taken as the research object to study its hepatoprotective and neuroprotective effect on AmB-induced liver and kidney damage in vitro and in vivo. The microplate method and ELISA kits were employed for the biochemical detection in the serum and urine of mice. Flow cytometric analysis and western blotting analysis were conducted to study the mechanism of DG and PF. Our results confirmed the prevention capacity of DG and PF on AmB-induced liver and kidney injury through the alleviation of pathological changes and enzyme reducing action. Furthermore, DG and PF suppressed ROS-mediated mitochondrial apoptosis in AmB-treated mice and cells through Caspase pathway and Caspase-independent AIF pathway. In summary, DG and PF could protect AmB-induced hepatotoxicity and nephrotoxicity by disrupting oxidative stress and apoptosis.

A phase II, non-comparative randomised trial of two treatments involving liposomal amphotericin B and miltefosine for post-kala-azar dermal leishmaniasis in India and Bangladesh.

BACKGROUND: In Southeast Asia, treatment is recommended for all patients with post-kala-azar dermal leishmaniasis (PKDL). Adherence to the first-line regimen, twelve weeks of miltefosine (MF), is low and ocular toxicity has been observed with this exposure period. We assessed the safety and efficacy of two shorter-course treatments: liposomal amphotericin B (LAmB) alone and combined with MF. METHODOLOGY/PRINCIPAL FINDINGS: An open-label, phase II, randomized, parallel-arm, non-comparative trial was conducted in patients with parasitologically confirmed PKDL, 6 to ≤60 years. Patients were assigned to 20 mg/kg LAmB (total dose, in five injections over 15 days) alone or combined with allometric MF (3 weeks). The primary endpoint was definitive cure at 12 months, defined as complete resolution of papular and nodular lesions and >80% re-pigmentation of macular lesions. Definitive cure at 24 months was a secondary efficacy endpoint. 118/126 patients completed the trial. Definitive cure at 12 months was observed in 29% (18/63) patients receiving LAmB and 30% (19/63) receiving LAmB/MF (mITT), increasing to 58% and 66%, respectively, at 24 months. Most lesions had resolved/improved at 12 and 24 months for patients receiving LAmB (90%, 83%) and LAmB/MF (85%, 88%) by qualitative assessment. One death, unrelated to study drugs, was reported; no study drug-related serious adverse events were observed. The most frequent adverse drug reactions were MF-related vomiting and nausea, and LAmB-related hypokalaemia and infusion reactions. Most adverse events were mild; no ocular adverse events occurred. CONCLUSIONS/SIGNIFICANCE: Both regimens are suitably safe and efficacious alternatives to long-course MF for PKDL in South Asia. TRIAL REGISTRATION: CTRI/2017/04/008421.

[Saksenaea caused invasive infection in an immunocompetent patient after trauma]. / Saksenaea-svamp gav invasiv infektion hos frisk traumapatient.

This text discusses a rare case of soft tissue infection caused by the fungus Saksenaea in a young, immunocompetent woman following an all-terrain vehicle accident abroad. Despite initial treatment, her wound worsened, necessitating multiple surgical revisions and aggressive antifungal therapy with liposomal Amphotericin B. The interdisciplinary collaboration among orthopedic surgeons, infectious disease specialists, and plastic surgeons played a vital role in her successful treatment. Prompt identification of the fungus and immediate intervention were crucial. This case emphasizes the importance of awareness among healthcare providers regarding this rare condition and underscores the significance of early diagnosis and timely surgical and medical interventions for a positive outcome.

Compare the efficacy of antifungal agents as primary therapy for invasive aspergillosis: a network meta-analysis.

BACKGROUND: Several antifungal agents are available for primary therapy in patients with invasive aspergillosis (IA). Although a few studies have compared the effectiveness of different antifungal agents in treating IA, there has yet to be a definitive agreement on the best choice. Herein, we perform a network meta-analysis comparing the efficacy of different antifungal agents in IA. METHODS: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Clinical Trials databases to find studies (both randomized controlled trials [RCTs] and observational) that reported on treatment outcomes with antifungal agents for patients with IA. The study quality was assessed using the revised tool for risk of bias and the Newcastle Ottawa scale, respectively. We performed a network meta-analysis (NMA) to summarize the evidence on antifungal agents' efficacy (favourable response and mortality). RESULTS: We found 12 studies (2428 patients) investigating 11 antifungal agents in the primary therapy of IA. There were 5 RCTs and 7 observational studies. When treated with monotherapy, isavuconazole was associated with the best probability of favourable response (SUCRA, 77.9%; mean rank, 3.2) and the best reduction mortality against IA (SUCRA, 69.1%; mean rank, 4.1), followed by voriconazole and posaconazole. When treated with combination therapy, Liposomal amphotericin B plus caspofungin was the therapy associated with the best probability of favourable response (SUCRA, 84.1%; mean rank, 2.6) and the best reduction mortality (SUCRA, 88.2%; mean rank, 2.2) against IA. CONCLUSION: These findings suggest that isavuconazole, voriconazole, and posaconazole may be the best antifungal agents as the primary therapy for IA. Liposomal amphotericin B plus caspofungin could be an alternative option.
