A recent article by Yerbanga, et al., (2024) titled “Epidemiology, Clinical Features and Antifungal Resistance Profile of Candida auris in Africa: Systematic Review” published in Journal of Biosciences and Medicines, examines that Candida auris shows very high resistance to fluconazole, moderate resistance to amphotericin B, and high susceptibility to echinocandins.

Candida auris prevalence in Africa, its resistance profile, and urgent need for proactive public health interventions.-Yerbanga, et al., 2024
The systematic review on the current page scrutinizes the prevalence and resistance patterns of Candida auris across Africa, shedding light on its epidemiology, clinical manifestations, and resistance to antifungal treatments. Notably, it underscores the paucity of comprehensive data in many African nations, indicating a critical gap in our understanding of this emerging pathogen’s impact on the continent’s healthcare landscape. Highlighting Candida auris as a formidable healthcare menace, the review accentuates its formidable resistance profile against conventional antifungal therapies, compounded by its propensity to incite outbreaks within healthcare facilities. This dual threat underscores the pressing need for proactive measures to curb its spread and mitigate its clinical consequences. Moreover, the study delves into the genetic diversity of C. auris, delineating four distinct phylogenetic clades prevalent in Africa. Within these clades, the review elucidates specific genetic mutations associated with antifungal resistance, providing valuable insights into the pathogen’s evolutionary trajectory and adaptive mechanisms. In light of these findings, the review advocates for a multifaceted approach to public health intervention, emphasizing the imperative of heightened awareness, stringent infection control measures, and robust research initiatives. By amplifying awareness and bolstering surveillance efforts, healthcare systems can better detect and contain outbreaks, thereby curtailing the dissemination of this insidious pathogen.
How the Study was Conducted
The authors utilized databases like PubMed, ScienceDirect, Google Scholar, and AJOL for articles related to the epidemiology, clinical features, and antifungal resistance of Candida auris in Africa. The authors explore original data reports such as case reports, series, and observational studies without date or design restrictions. Excluded commentary articles and studies outside African countries and also extract data which involved screening titles, abstracts, and full texts by two independent reviewers, with discrepancies resolved through discussion or a third reviewer. In addition, the authors followed PRISMA guidelines for systematic reviews, focusing on prevalence, risk factors, case fatality rate, phylogenetic clades, clinical features, and antifungal resistance profile of C. auris
What the Authors Found
The authors found that the prevalence of Candida auris in Africa is 8.74%, with data reported from only 6 African countries. South Africa has the most reported cases. The authors also found that the main risk factors include cardiovascular disease, renal failure, diabetes, HIV, recent intake of antimicrobial drugs, ICU admissions, surgery, hemodialysis, parenteral nutrition, and indwelling devices. In addition, the study posits that Candida auris shows very high resistance to fluconazole, moderate resistance to amphotericin B, and high susceptibility to echinocandins.
Why is this important
Healthcare Preparedness: Understanding the prevalence, risk factors, and resistance patterns of C. auris helps healthcare systems prepare for potential outbreaks. Early detection and containment are critical to prevent its spread.
Antifungal Treatment Strategies: The high resistance to fluconazole and moderate resistance to amphotericin B highlight the need for alternative antifungal therapies. Echinocandins remain effective, but targeted treatment based on resistance profiles is essential.
Phylogenetic Insights: Clade-specific mutations associated with antifungal resistance provide insights into the evolution of C. auris. This knowledge can guide research on novel drug targets and therapeutic approaches.
Public Health Interventions: The study emphasizes the importance of surveillance, infection control measures, and awareness campaigns. Healthcare professionals and policymakers can use this information to develop effective strategies.
Global Impact: As a multidrug-resistant pathogen, C. auris poses a global threat. By studying its behavior in Africa, we contribute to the broader understanding of this emerging pathogen.
What the Authors Recommend
- The authors suggest that stakeholders should improve surveillance systems to track the prevalence, incidence, and distribution of C. auris cases across African countries. This includes standardized reporting mechanisms and collaboration between healthcare facilities.
- The authors suggest that stakeholders implement strict infection control protocols in healthcare settings. These should include measures to prevent nosocomial transmission, such as proper hand hygiene, isolation precautions, and environmental cleaning.
- The study recommends that healthcare authorities develop guidelines for appropriate antifungal use. Given the high resistance to fluconazole, judicious use of antifungal agents is crucial. Echinocandins should be considered as first-line therapy.
- Healthcare authorities should strengthen laboratory infrastructure for accurate identification and antifungal susceptibility testing of C. auris. This includes training personnel, ensuring access to necessary reagents, and quality assurance, and educating healthcare professionals, patients, and the public about C. auris. Awareness campaigns can help prevent outbreaks and promote early detection.
- Furthermore, healthcare authorities should encourage research on novel antifungal agents, vaccine development, and understanding the genetic basis of resistance. Collaborate across borders to share knowledge and resources.
In conclusion, the systematic review sheds crucial light on the evolving landscape of Candida auris in Africa, emphasizing its prevalence, resistance patterns, and the imperative for proactive public health measures. With a pressing need for enhanced surveillance, robust infection control protocols, and judicious antifungal strategies, stakeholders must unite in a concerted effort to combat this formidable pathogen. By fostering collaboration, bolstering research endeavors, and amplifying awareness, we can fortify healthcare systems and mitigate the impact of Candida auris, safeguarding the health and well-being of communities across the continent and beyond.
