World J Clin Cases 2024; 12:6077-6086. [DOI: 10.12998/wjcc.v12.i27.6077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Revised: 06/23/2024] [Accepted: 07/15/2024] [Indexed: 07/29/2024] Open
Abstract
BACKGROUND Oral candidiasis (OC) is an oral health disease that could influence patients’ oral health quality of life.
AIM To estimate prevalence of OC among disabled and non-disabled individuals and its potential risk factors in the Al-Baha region, Saudi Arabia.
METHODS An observational cross-sectional study was carried out among 148 disabled and non-disabled participants. The technique of concentrated oral rinse employing the Sabouraud Dextrose Agar medium accompanied with 0.05% chloramphenicol was conducted to assess and isolate candida. Oral examination using the World Health Organization guidelines was conducted to examine participants’ oral health status. A pre-designed questionnaire was also used to evaluate sociodemographic, medical history, and oral hygiene habits of the studied population.
RESULTS Out of 148 participants (n = 57, 38%) had colonized candida. None of the studied population had visible Candida lesions. However, Candida was found in the oral rinses without the subject presenting any lesions or issues caused by Candida (asymptomatic colonization). The most common prevalent OC among participants were Candida albicans,Candida glabrata, Candida dubliniensis, Candida krusei, Candida tropicalis, and Candida parapsilosis (n = 35, 61%; n = 8, 14%; n = 6, 10%; n = 5, 9%; n = 2, 4%; and n = 1, 2%) respectively. Diabetes, smoking, poor plaque, and gingival status were key potential risk factors that significantly associated with candida’s density and presence (P = 0.001, P = 0.001, P = 0.01, and P = 0.01) respectively. Disability status had no statistically significant effect on presence and density of Candida.
CONCLUSION The prevalence of OC is almost third of the studied population; thus, may provoke a need to develop preventive strategies to reduce the OC rate and establish solid treatment plans.

Arch Oral Biol 2024; 157:105827. [PMID: 37918303 DOI: 10.1016/j.archoralbio.2023.105827] [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: 04/04/2023] [Revised: 10/10/2023] [Accepted: 10/16/2023] [Indexed: 11/04/2023]
Abstract
OBJECTIVE This study aimed to elucidate the difference in virulence of Candida albicans derived from oral candidiasis and non-oral candidiasis patients, and its genotype differences in Hokkaido to obtain a clue of a platform to develop new approaches for diagnosis and treatment. DESIGN C. albicans strains were collected from patients who visited the Hokkaido University Hospital Dental Center. Each strain was examined to i) identify the Candida albicans genotype by PCR, ii) measure the strain's extracellular secretory enzyme activity, iii) determine the strain's ability to induce the production of interleukin-8, and iv) determine the strain's ability to induce cell death. RESULTS Certain virulence-related protease activities and cytotoxicity were higher in strains derived from patients with oral candidiasis compared with strains derived from patients without oral candidiasis. This is the first report on genotypes and the virulence-related activities, such as some protease secretion, IL-8 induction and cytotoxicity of C. albicans in Hokkaido. CONCLUSIONS The virulence-related activities of the fungal strain may influence the pathogenesis of oral candidiasis, such as production of secreted aspartyl protease and cytotoxicity. In addition, C. albicans genotype C may be important for pathogenicity in Hokkaido, because the ratio of genotype C was increased in strains derived from oral candidiasis patients.

Abstract
Our understanding of the relationship between oral Candida and systemic conditions has significantly increased recently, which this study aims to extend further by investigating the risks of oral candidiasis. A total of 314 patients were involved in this study and underwent an oral swab test at the Department of Oral Medicine, Hokkaido University Hospital, between January and December 2021. Data were collected on age, sex, white and red blood cell counts, Hb, total protein, vitamin B12, as well as serum albumin, iron, copper, and zinc levels. The clinical fungus samples were swabbed to identify those with Candida species using a MALDI Biotyper, then applied analysis of covariance and multivariant logistic regression analysis. It was possible to assess the oral swab test results without considering the difference between sex (p = 0.946). The oral swab test results were associated with aging (odds ratio: 1.03) and serum albumin levels (odds ratio: 0.32). In summary, the results of our study suggest a relationship between aging and oral candidiasis and offer in-depth insights into how to prevent or treat oral candidiasis onset.

Molecular mechanisms of azole resistance in Candida glabrata isolated from oropharyngeal candidiasis in head and neck cancer patients. Arch Oral Biol 2023; 154:105757. [PMID: 37419061 DOI: 10.1016/j.archoralbio.2023.105757] [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: 03/18/2023] [Revised: 06/24/2023] [Accepted: 06/29/2023] [Indexed: 07/09/2023]
Abstract
OBJECTIVE The aim of the current work was to assess the molecular mechanisms of fluconazole-resistant Candida glabrata strains isolated from oropharyngeal candidiasis (OPC) in head and neck patients, as well as evaluation of virulence factors. DESIGN Antifungal susceptibility pattern of sixty six clinical isolates of C. glabrata were evaluated by broth-microdilution method. The expression of ERG11, CDR1, CDR2, PDR1 genes as well as ERG11 gene capable of possible mutations was also detected in 21 fluconazol-resistant C. glabrata isolates. Phospholipase and proteinase activity of these isolates was estimated, too. The correlation between the virulence factors, antifungal susceptibility patterns and cancer type was also analyzed. RESULTS Seven synonymous and four non-synonymous mutations were found in 21 fluconazole-resistant C. glabrata isolates; subsequently, four amino acid substitutions including H257P, Q47H, S487Y and I285N were then reported for the first time. High expression of CDR1 and PDR1 in related to other gene findings were tested in these isolates. Additionally, there was no significant difference between stage of cancer and MIC of all antimicrobial drugs. Significant differences between MIC of fluconazole, voriconazole and cancer types were also, found. The proteinase activity (92.4%) was higher than phospholipase activity in the isolates. Further, no significant difference between proteinase (rs: 0.003), phospholipase (rs: -0.107) activity and fluconazole MICs was observed. CONCLUSION C. glabrata isolated from OPC in head and neck patients represented high capacities for proteolytic enzymes activity and high mRNA level of CDR1 and PDR1 gene and ERG11 mutations play an important role in azole drug resistance.

Abstract
Predicting evolution is a fundamental problem in biology with practical implications for treating antimicrobial resistance, which is a complex system-level phenomenon. In this perspective article, we explore the limits of predicting antimicrobial resistance evolution, quantitatively define the predictability and repeatability of microevolutionary processes, and speculate on how these quantities vary across temporal, biological, and complexity scales. The opportunities and challenges for predicting antimicrobial resistance in the context of systems biology are also discussed. Based on recent research, we conclude that the evolution of antimicrobial resistance can be predicted using a systems biology approach integrating quantitative models with multiscale data from microbial evolution experiments.

Abstract
Cigarette smoking is regarded as a major global health risk, therefore the aim of this work was to investigate the association of oral Candida spp. as one of the etiological agents of denture stomatitis with smokers of cigarette, hookah (shisha), and electronic smoking, also a dose-response relationship between the duration of smoking and the probability of denture stomatitis between volunteers. Oral rinse samples were collected from 47 male volunteers including 34 smokers and 13 non-smokers, also data of volunteers were collected via a questionnaire forum. Patterns of smoking were shown that smokers using tobacco cigarettes 17 (36.2 %), electronic cigarettes 16 (34.04 %), and hookah smokers 8 (17.02 %). A comparison of smokers and non-smokers regarding effects on oral health showed significantly finding (P < 0.05) indicating that smoking affects oral health in all evaluated parameters (an oral mucosal abnormality, mouth ulcers, bad breath, and feeling of dry mouth). Out of 19 Candida isolates, 18 (94.7 %) were identified as Candida albicans and 1 (5.3 %) as Candida tropicalis. Among the volunteers who presented with oral Candida (19 volunteers), 17 (89.5%) were smokers, while non-smoker volunteers were 2 (10.5 %), so it can be concluded that smoking was a significant positive correlation to the presence of Candida in the oral cavity. Five volunteers suffered from chronic diseases; 4 (8.5%) diabetes mellitus and 1 (2.1%) anemia as a systemic predisposing factor for oropharyngeal infection. Amphotericin and Nystatin had varying degrees of activity against isolated Candida isolates.

Abstract
Recent years have been marked by a paradigm shift in the study of the human microbiota, with a re-emergence of culture-dependent approaches. Numerous studies have been devoted to the human microbiota, while studies on the oral microbiota still remain limited. Indeed, various techniques described in the literature may enable an exhaustive study of the microbial composition of a complex ecosystem. In this article, we report different methodologies and culture media described in the literature that can be applied to study the oral microbiota by culture. We report on specific methodologies for targeted culture and specific culture techniques and selection methodologies for cultivating members of the three kingdoms of life commonly found in the human oral cavity, namely, eukaryota, bacteria and archaea. This bibliographic review aims to bring together the various techniques described in the literature, enabling a comprehensive study of the oral microbiota in order to demonstrate its involvement in oral health and diseases.
