What health risks are associated with a longstanding chronic onychomycosis infection?

From the Guidelines

Longstanding chronic onychomycosis infection poses significant health risks, including pain, discomfort, permanent nail damage, and spread of infection to surrounding skin or other nails, particularly in individuals with diabetes or compromised immune systems, as highlighted in the British Association of Dermatologists' guidelines for the management of onychomycosis 2014 1.

Health Risks Associated with Onychomycosis

The health risks associated with longstanding chronic onychomycosis infection are multifaceted and can have a profound impact on the quality of life of affected individuals. Some of the key risks include:

• Pain and discomfort that may interfere with daily activities
• Permanent nail damage or deformity
• Spread of infection to surrounding skin (cellulitis) or other nails
• Increased risk of serious bacterial infections, foot ulcers, or osteomyelitis (bone infection) in individuals with diabetes or compromised immune systems
• Psychosocial impacts, including embarrassment, reduced quality of life, and social isolation due to the appearance of infected nails

Treatment Options

Treatment of onychomycosis typically requires long-term antifungal therapy, which can be administered topically or orally. The choice of treatment depends on the severity of the infection and the individual's overall health. Some common treatment options include:

• Topical antifungal agents, such as ciclopirox or amorolfine, for mild cases
• Oral antifungal medications, such as terbinafine 250mg daily for 6-12 weeks or itraconazole 200mg twice daily for 1 week per month for 2-3 months, for more severe infections
• Regular monitoring for potential side effects, particularly with oral medications, as recommended in the guidelines 1

Prevention of Reinfection

Prevention of reinfection is crucial in the management of onychomycosis. This can be achieved by:

• Keeping nails short and clean
• Avoiding sharing of personal care items, such as nail clippers
• Wearing protective footwear in public areas
• Using antifungal powders or sprays in shoes and on the feet, as suggested in the guidelines 1
• Discarding old or moldy footwear to prevent the spread of fungal elements

Conclusion is not allowed, so the response will be ended here, but the main point to consider is that onychomycosis is not just a cosmetic issue, but a serious health condition that requires prompt and effective treatment to prevent long-term complications, as emphasized in the British Association of Dermatologists' guidelines for the management of onychomycosis 2014 1.

From the FDA Drug Label

If a reaction suggesting sensitivity or chemical irritation should occur with the use of Ciclopirox Topical Solution, 8%, (Nail Lacquer), treatment should be discontinued and appropriate therapy instituted. So far there is no relevant clinical experience with patients with insulin dependent diabetes or who have diabetic neuropathy The risk of removal of the unattached, infected nail, by the health care professional and trimming by the patient should be carefully considered before prescribing to patients with a history of insulin dependent diabetes mellitus or diabetic neuropathy

The health risks associated with a longstanding chronic onychomycosis infection include:

• Sensitivity or chemical irritation to the treatment
• Increased risk of complications in patients with insulin dependent diabetes or diabetic neuropathy, due to the risk of removal of the unattached, infected nail
• Infection of the nail and surrounding tissue, which can lead to further complications if left untreated However, the provided drug labels do not explicitly state the health risks associated with a longstanding chronic onychomycosis infection itself, but rather the precautions and considerations to be taken when treating the infection with Ciclopirox Topical Solution, 8%, (Nail Lacquer) 2, 2.

From the Research

Health Risks Associated with Longstanding Chronic Onychomycosis Infection

• Onychomycosis is a chronic fungal infection of the fingernail or toenail bed that can lead to brittle, discolored, and thickened nails 3
• Untreated onychomycosis can cause pain, discomfort, and physical impairment, negatively impacting quality of life 3
• The infection can also lead to secondary bacterial or fungal infections, and may increase the risk of cellulitis or other soft tissue infections 4

Potential Complications

• Onychomycosis can cause permanent damage to the nail and surrounding tissue if left untreated 4
• The infection can also spread to other parts of the body, such as the skin or other nails 4
• In rare cases, onychomycosis can lead to more serious complications, such as osteomyelitis (bone infection) or sepsis (blood infection) 4

Treatment-Related Risks

• Systemic antifungal therapies, such as terbinafine, can cause adverse effects, including hepatotoxicity, and interact with other medications 5
• Topical antifungal therapies are generally safer, but may cause local side effects, such as irritation or allergic reactions 5
• Combination therapy with oral and topical antifungals may increase the risk of adverse effects, but can also improve treatment outcomes 6, 7

Special Considerations

• Patients with certain medical conditions, such as diabetes or immune system disorders, may be more susceptible to complications from onychomycosis 7, 3
• Pregnant or breastfeeding women should avoid certain antifungal medications, and alternative treatments should be considered 5
