Amphotericin B (AmB) has long stood as a cornerstone in the treatment of invasive fungal infections (IFIs), especially among immunocompromised patients. However, the landscape of antifungal therapy is evolving. New antifungal agents, boasting novel mechanisms of action and better safety profiles, are entering the scene, presenting alternatives to AmB’s traditional dominance. This shift, prompted by an increase in the incidence of IFIs, the growing demographic of immunocompromised individuals, and changing patterns of fungal resistance, underscores the continuous need for effective treatments. Despite these challenges, AmB’s broad efficacy and low resistance rates maintain its essential status in antifungal therapy. Innovations in AmB formulations, such as lipid complexes and liposomal delivery systems, have significantly mitigated its notorious nephrotoxicity and infusion-related reactions, thereby enhancing its clinical utility. Moreover, AmB’s efficacy in treating severe and rare fungal infections and its pivotal role as prophylaxis in high-risk settings highlight its value and ongoing relevance. This review examines AmB’s standing amidst the ever-changing antifungal landscape, focusing on its enduring significance in current clinical practice and exploring its potential future therapeutic adaptations.

Macrophage activation syndrome (MAS) is a life-threatening systemic hyperinflammatory syndrome triggered by various infections, particularly viral infections, autoimmune disorders, and malignancy. The condition is characterized by an increased production of proinflammatory cytokines resulting in a cytokine storm and has been associated with poor clinical outcomes. During the COVID-19 pandemic, patients with severe manifestations developed features similar to those of MAS, although these characteristics remained well defined within the lung. Additionally, other viral infections including EBV, the herpes family of viruses, hepatitis viruses, influenza, HIV, and hemorrhagic fevers can be complicated by MAS. The diagnosis and management of the condition remain challenging due to the lack of consensus on specific guidelines, especially among the adult population. Currently, therapeutic options primarily rely on medications that are typically used to treat primary hemophagocytic lymphohistiocytosis, such as corticosteroids and etoposide. In addition, cytokine-targeted therapies present promising treatment options. The objective of this review is to discuss the emergence of MAS in the context of viral infections including, but not limited to, its occurrence in COVID-19.

Background/Objectives: Vulvovaginal candidosis (VVC) is a common condition among women, with current diagnostic methods relying on clinical evaluation and laboratory testing. These traditional methods are often limited by the need for specialized training, variable performance, and lengthy diagnostic processes, leading to delayed treatment and inappropriate antifungal use. This review evaluates the efficacy of molecular diagnostic tools for VVC and provides guidance on their application in clinical practice. Methods: A literature search was conducted using PubMed to identify studies evaluating rapid diagnostic tests specifically for vulvovaginal Candida isolates. Inclusion criteria focused on studies utilizing molecular diagnostics for the detection of Candida species in VVC. Articles discussing non-vaginal Candida infections, non-English studies, and animal or in vitro research were excluded. Results: Twenty-three studies met the inclusion criteria, predominantly evaluating nucleid acid amplification tests/polymerase chain reaction (NAAT/PCR) assays and DNA probes. PCR/NAAT assays demonstrated high sensitivity and specificity (>86%) for VVC diagnosis, outperforming conventional diagnostic methods. Comparatively, DNA probes, while simpler, exhibited lower sensitivity. The included studies were mostly observational, with only one randomized controlled trial. Emerging diagnostic technologies, including artificial intelligence and integrated testing models, show promise for improving diagnostic precision and clinical outcomes. Conclusions: Molecular diagnostics offer a significant improvement in VVC management, though traditional methods remain valuable in resource-limited settings.

Bone infections, including osteomyelitis, prosthetic joint infections, and fracture-related infections, represent a persistent and growing clinical problem associated with substantial morbidity, mortality, and healthcare costs. Their management is complicated by limited bone vascularization, biofilm formation, intracellular bacterial persistence, dysregulated host immune responses and reduced antibiotic delivery to the infection site, which promote chronic infection and recurrence. The limitations of conventional treatment strategies based on surgical debridement and prolonged systemic antibiotic therapy, together with their association with antimicrobial resistance and systemic toxicity, have led to growing interest in alternative and adjunctive therapeutic approaches. Local antibiotic delivery systems, such as polymethyl methacrylate, calcium sulfate, hydroxyapatite-based composites, hydrogels, antibiotic-impregnated bone grafts, and nanoparticle carriers, enable high local antimicrobial concentrations while minimizing systemic exposure. From a different therapeutic perspective, immunomodulatory strategies, including mesenchymal stem cell-based therapies, cytokine-targeted interventions, bacteriophages, quorum-sensing inhibitors, and non-antibiotic antimicrobials, represent emerging approaches aimed at improving infection control and supporting bone regeneration. Advances in biomarker profiling, molecular diagnostics, and artificial intelligence-assisted analyses further support personalized approaches to diagnosis, monitoring, and treatment. Despite encouraging early results, clinical translation remains limited by methodological and regulatory challenges, underscoring the need for integrated, innovative treatment strategies.

Hepatitis E virus (HEV) poses significant health concerns worldwide, particularly among people living with HIV (PLWHIV), due to an increased risk of chronic infection and progression to cirrhosis in individuals with low CD4 cell counts. This study aimed to investigate the prevalence, chronicity potential, and risk factors of HEV infection among PLWHIV in Greece, where data are currently absent. A synchronic multicentric study encompassing five major Greek university hospitals was executed over 24 months, recruiting 696 PLWHIV participants. The prevalence of HEV IgG antibodies was 16.5%, with 8.6% showing evidence of acute HEV infection (HEV IgM). Active viral replication (HEV RNA) was present in 2.3% of the study population. Longitudinal analysis revealed that of the 25 initially anti-HEV IgM-positive individuals, only 3 seroconverted to IgG positivity, and among those with prior HEV RNA positivity (16), none showed evidence of active replication in subsequent tests. Comparative subgroup analysis highlighted the lack of significant differences in HIV-related parameters between HEV seropositive and seronegative individuals. Laboratory evaluations generally showed no significant disparities across most parameters; however, a higher seropositivity for Hepatitis A was observed in the HEV-positive subgroup. Our findings highlight a considerable prevalence of HEV among PLWHIV in Greece, with no observed cases of chronicity.

Infective endocarditis (IE) during pregnancy, while uncommon, is associated with substantial maternal and fetal morbidity and mortality due to the complex physiological adaptations of pregnancy. Hemodynamic alterations, including increased cardiac output and changes in vascular resistance, combined with immunological modulation, predispose pregnant individuals to increased risk of infection and associated complications. Predominant pathogens implicated in pregnancy-associated IE are Staphylococcus aureus, Streptococcus viridans, and Enterococcus faecalis, with S. aureus infections frequently leading to poorer clinical outcomes. Diagnosis remains challenging due to commonly atypical presentation and relies on microbiological identification via blood cultures in conjunction with imaging modalities such as transthoracic echocardiography. IE in pregnancy is associated with increased maternal mortality rates (5–17%) and adverse fetal outcomes, including preterm birth, intrauterine growth restriction (IUGR), and fetal loss. Management necessitates careful selection of antimicrobial therapy to ensure efficacy while minimizing fetal toxicity, especially in settings of increased antimicrobial resistance. Anticoagulation and surgical interventions must be judiciously considered, with surgical timing individualized based on the severity of heart failure and coordinated multidisciplinary care. In conclusion, IE during pregnancy constitutes a significant clinical challenge, underscoring the need for enhanced diagnostic strategies, optimized therapeutic protocols, and the development of pregnancy-specific management guidelines to improve maternal and fetal outcomes.
