Unexplored Root Causes Behind Ineffective Toenail Fungus Treatments
Berlin, Germany - A recent study by researchers reveals that the majority of toenail fungus treatments fail due to an overlooked root cause. The treatment's inability to address this underlying issue significantly contributes to its ineffectiveness.
The hard and keratinized nail structure, along with the fungus' resilience, makes it challenging for topical medications to penetrate sufficiently and reach the site of infection, particularly in thick or dystrophic nails. Furthermore, the slow growth rate of nails means that even successful treatments may take several months to exhibit results, often resulting in patients discontinuing therapy before the infection is fully eradicated.
Another concern is the emergence of antifungal resistance, notably against terbinafine, the most effective oral antifungal. Fungi with mutations in their squalene epoxidase gene can become resistant to this drug, complicating treatment. Moreover, the risk of relapse (about 20–25% within two years) due to reinfection from the environment, untreated fungal infections elsewhere on the body, or persistent fungal spores contributes to the treatment's failure.
Other contributing factors include poor adherence to the treatment regimen, misdiagnosis, and anatomical or health issues such as diabetes, poor circulation, advanced age, and ongoing trauma to the nail. The root cause of most treatment failures is the combination of poor drug penetration into the nail, slow nail growth requiring prolonged therapy, patient noncompliance, and the risk of recurrence or reinfection, according to the study. In addition, growing concerns about increasing antifungal resistance (especially to terbinafine) further complicate successful treatment.
It is essential for medical professionals and pharmacies to acknowledge these root causes and develop strategies to address them for more effective treatment options for toenail fungus infections.
- To improve the effectiveness of toenail fungus treatments, it's crucial for medical professionals and pharmacies to focus on addressing the root causes, such as poor drug penetration into the nail, slow nail growth, patient noncompliance, and the risk of recurrence or reinfection.
- In the realm of health-and-wellness and skin-care, further research and development in science are required to better understand and tackle medical-conditions like toenail fungus, particularly in view of the growing concerns about antifungal resistance, especially against terbinafine.
