Summary: Expanding the antifungal drug arsenal is crucial for treating Candida infections, which are increasing in prevalence and often resistant to existing treatments. This review provides a comprehensive summary of antimicrobial peptides (AMPs) with anti-Candida activity that have undergone successful preclinical or clinical trials. The source, mode of action, and animal model of infection or clinical trial for these AMPs are presented. The advantages of combination therapy using AMPs and other drugs to fight Candida infections are also discussed.

Summary: Oral candidiasis remains a common opportunistic fungal infection among PLWHA in the era of HAART. Though there is an increasing prevalence of new Candida species, Candida albicans still remains the predominant species. Low BMI and CD4 count <= 200 cells/mm³ are predictors of OC occurrence.

Summary: Oropharyngeal candidiasis (OPC) is a common infection that can range from mild to severe, depending on the patient. The transcriptional regulation of C. albicans biofilm formation on abiotic surfaces involves six key factors, some of which play roles in OPC infectivity in a mouse model. The relationship between fungal burden, hyphae morphogenesis, and infectivity is of significant research interest.

Summary: Oropharyngeal candidiasis (OPC) is a common infection that can cause mild or severe disease depending on the patient. The transcriptional regulation of C. albicans biofilm formation on abiotic surfaces is also involved in OPC, but the network characteristics and functional connections during infection are distinct from those observed in vitro.

Summary: Candida albicans, a commensal of the human gastrointestinal tract, is a common cause of human fungal disease. This study compared the gene expression profiles of C. albicans during oral infection and disseminated infection of the kidney, revealing niche-specific differences in gene expression. The findings shed light on the interactions between the pathogen and the host.

Summary: This study characterized mature biofilms of various Candida species obtained from the oral mucosa of children, adults, and elders. It was found that children were more likely to be infected by non-Candida albicans Candida species (NCACs) and these NCACs formed biofilms richer in matrix components. This finding is clinically important, especially in pediatric care, due to the association of stronger biofilms with antimicrobial resistance, recurrent infections, and higher therapeutic failure.

Summary: Oral candidiasis is a common fungal infection in people living with HIV/AIDS. A study was conducted to analyze the susceptibility profiles of Candida spp. to six antifungal agents. The prevalence of oral Candida infection was 34.06%. The study found low-level resistance to some antifungal agents and identified mixed infections and multidrug resistance in some patients.

Summary: Oropharyngeal candidiasis (OPC) is a common infection caused by Candida albicans, with high mortality rates. The limited treatment options and increasing drug resistance highlight the need for new drugs. This study confirmed that riboflavin (RF) has broad-spectrum anti-Candida activity by inhibiting hyphae and biofilm formation. Mechanistically, RF disrupts membrane and cell wall integrity and promotes reactive oxygen species and pyruvate accumulation. RF also targets multiple essential pathways. In a mouse model of OPC, RF exhibited therapeutic efficacy and potential benefits in treating OPC.

Summary: Oropharyngeal candidiasis (OPC) is a type of oral infection caused by Candida albicans. This study found that the combination therapy of paeonol (PAE) plus fluconazole (FLU) or amphotericin B (AmB) can reduce fungal burden, restore mucosal integrity, and decrease the hypoxic microenvironment and inflammation in OPC mice. Furthermore, the drug combinations can also rectify the abnormal expression of hypoxia-inducible factor (HIF)-1 alpha, IL-17A, and IL-23 mRNA.

Summary: Oral bacteria can influence the virulence of Candida albicans in causing oropharyngeal candidiasis (OPC). A prebiotic diet enriched with xylo-oligosaccharides (XOS) can modulate the oral microbiome composition and attenuate Candida infection in an OPC mouse model.

Summary: This study examines a novel pathogen, Candida haemulonii, causing cutaneous infection in a Boa constrictor snake. The fungus was identified and its drug sensitivity was tested, revealing strong inhibition for all drugs except fluconazole and itraconazole. A biogenic silver nanoparticle-based ointment successfully treated the clinical symptoms in the snake. The presence of these infections in snakes near human habitats highlights the importance of wildlife health monitoring for emerging and opportunistic diseases in peri-urban environments.

Summary: Cardiac channelopathies are a group of inherited cardiac diseases that are associated with mutations in genes encoding cardiac ion channels. The two main hereditary arrhythmias in children and adolescents, Brugada Syndrome and Long QT Syndrome, show different clinical manifestations. Brugada Syndrome is more commonly observed in this population and is characterized by episodes of syncope or sudden cardiac death. On the other hand, Long QT Syndrome has a milder phenotype but requires monitoring and correction of electrolyte disturbances.

Summary: The engineered salivary peptide DR9-RR14 has been shown to effectively reduce enamel demineralization, but has no significant impact on biofilm biomass or the expression of cariogenic bacterial proteins. This suggests that DR9-RR14 may primarily control caries development through a physicochemical mechanism.

Summary: Salivary proteins play an important role in the repair of damaged tissues and the maintenance of oral health. This systematic review aimed to assess the association between caries and salivary proteins by comparing caries-free (CF) and caries-active (CA) individuals. The results showed that the levels of certain salivary proteins were significantly increased in CA patients, while others were significantly increased in CF subjects. However, there were conflicting results regarding the salivary levels of immunoglobulin-A and total proteins among CA and CF subjects. Due to significant heterogeneity among the included studies, no meta-analysis could be performed. Therefore, larger prospective studies are needed to verify the diagnostic value of salivary proteins as biomarkers for caries.
