Itraconazole pulse therapy improves the quality of life of patients with toenail onychomycosis

More than Nail Deep: The Effect of Efinaconazole 10% Treatment on the Quality of Life in Patients with Onychomycosis: A post hoc Study

INTRODUCTION

Onychomycosis is a common, difficult-to-treat fungal nail infection. Clinical signs include nail discoloration and thickening, which patients often find embarrassing, causing a negative impact on their quality of life (QOL).

METHODS

In this post hoc study, we analyze the effect of efinaconazole 10% solution on a patient's QOL using patient-reported scores from the OnyCOE-t™ questionnaire (appearance, stigma, physical problems, symptom frequency, symptom bothersomeness, treatment satisfaction, and overall problem). Higher scores corresponded to better functioning, thus higher QOL.

RESULTS

Efinaconazole 10% treatment and clinical efficacy were positively correlated with improved QOL in all domains for all groups, except with symptom bothersomeness (how much the onychomycosis symptoms worried or concerned the patient) for female patients <40 years. While still showing improvement in most domains during efficacious treatment, female and younger patients reported lower QOL scores than their male and older counterparts, despite having better clinical outcomes at follow-ups.

DISCUSSION

Female and younger patients appear to be more emotionally bothered by their symptoms, regardless of treatment success or improvement of their nail's appearance, suggesting that onychomycosis is more than nail deep and has a greater psychological effect on these patients. Therefore, younger female patients may require more assurance and mental support.

Effect of onychomycosis and treatment on patient-reported quality-of-life outcomes: A systematic review

BACKGROUND

Onychomycosis is the most common nail disorder, often causing physical, emotional, and aesthetic consequences. The effect of both the condition itself and treatment on quality of life has not been well studied.

OBJECTIVE

The objectives of this study were to systematically review the available literature describing the effect of onychomycosis and treatment on quality of life.

METHODS

We performed a search of the onychomycosis literature published before April 13, 2020. Articles were included in the review if primary data were presented, patient-reported outcome measures were used, and onychomycosis was specifically examined.

RESULTS

Thirty studies were included in the final analysis. Poorest quality-of-life scores were associated with women and fingernail involvement. Quality-of-life scores improved from baseline with all treatment types; there were greater improvements reported with oral treatments compared with topical ones.

CONCLUSIONS

This review affirms that onychomycosis significantly influences quality of life, warranting effective treatment. All treatments resulted in quality-of-life improvements; however, studies on oral and topical therapies were of higher quality than those evaluating devices. Increased efforts are needed to understand the effect of the disease and therapy as assessed by validated, nail-specific outcome measures that accurately assess patients' cosmetic, physical, and social difficulties.

[Prevalence of dermatomycoses in professional football players : A study based on data of German Bundesliga fitness check-ups (2013-2015) compared to data of the general population]

BACKGROUND

The prevention, early diagnosis and treatment of onychomycosis is of great importance for professional athletes to avoid physical limitations by complications. So far, there is only little data on the prevalence of dermatomycosis in professional athletes.

OBJECTIVES

The aim of the study was to detect the prevalence of dermatomycosis in professional football players compared to the general population.

MATERIALS AND METHODS

The prospective, non-interventional, controlled study on the prevalence of dermatomycosis in professional football players was carried out on football players of a German Bundesliga team compared with a previously studied, equivalently aged German working population. A questionnaire survey, a dermatological check-up and a microbiological detection of pathogens in cases of suspicion were performed.

RESULTS

Data of 84 football players (n = 45 in 2013; n = 39 in 2015) were compared to data of n = 8186 male employees between 17 and 35 years of age. In the group of athletes, there were findings of 60.7% onychomycosis, 36.9% of tinea pedis and 17.8% of pityriasis versicolor. In the group of the age-equivalent general German working population the findings were: onychomycosis 3.3%, tinea pedis 3.2%, pityriasis versicolor 1.4%.

CONCLUSION

Our study shows a clearly higher risk for fungal diseases of the skin especially on the feet of professional football players. The results show a necessity for elucidation within prevention and the establishment of an appropriate therapy of dermatomycosis for professional football players.

Patient-Reported Outcomes in Onychomycosis: A Review of Psychometrically Evaluated Instruments in Assessing Treatment Effectiveness

PURPOSE

Onychomycosis is the most common nail disorder and causes morbidity and impaired quality of life (QOL). Patient-reported outcomes (PRO) are patients' assessment of their health status or treatment response. PROs help assess what is most bothersome to patients to identify targets for intervention. We sought to review the PRO instruments currently used to assess QOL and treatment response in onychomycosis patients.

PROCEDURES

A systematic review was performed by searching PubMed, Embase, CINAHL, and PsycINFO databases through December 31, 2016, to identify all English language literature on onychomycosis, PRO, and QOL.

RESULTS

Currently, 5 validated PRO instruments exist specifically for onychomycosis. Oral therapies were most extensively studied using PRO instruments. QOL data generally correlated with clinical change, although patients sometimes reported improvement without any clinically significant nail clearance. The only psychometrically validated PRO instrument used to evaluate treatment response is the OnyCOE-t™.

CONCLUSIONS

Clinicians may underestimate the impact of onychomycosis on patients. With recent initiatives from health-care management organizations to improve patient experience and the recent approval of expensive and nonsuperior topical antifungal medications, PROs will be increasingly important in onychomycosis to assess patient priorities and optimize treatment. Future research should evaluate these instruments in special populations and fingernail disease.

Clinical study of Dermatophyte Test Strip, an immunochromatographic method, to detect tinea unguium dermatophytes

The Dermatophyte Test Strip visualizes mycotic antigens by immunochromatography. It allows easy and fast detection of dermatophytes. A multicenter, single-arm, comparative clinical study was designed to evaluate the capacity of Dermatophyte Test Strip to detect dermatophytes in suspected tinea unguium specimens in comparison with direct microscopy and polymerase chain reaction (PCR). Signed consent was obtained from 222 subjects and all subjects completed the study. With the Dermatophyte Test Strip, dermatophytes were detected in 201 of 222 (90.5%) specimens but not in 21 of 222 (9.5%) specimens. With direct microscopy, dermatophytes were detected in 170 of 222 (76.6%) specimens but not in 52 of 222 (23.4%). Of the 45 specimens that showed inconsistent results between the two methods, PCR gave further results for 40 specimens, of which 37 (92.5%) specimens were positive and three (7.5%) were negative for dermatophytes. The positive concordance rate, negative concordance rate and overall concordance rate between the Dermatophyte Test Strip and direct microscopy were 81.1%, 66.7% and 79.7%, respectively. When inconsistent results were corrected using the results of PCR, these rates were 97.5%, 71.4% and 95.0%, respectively. When five specimens that could not be tested by PCR because no piece for the PCR test was left were excluded from analysis, these rates were 99.0%, 78.9% and 97.2%, respectively. The present results indicate good detection capacity of the Dermatophyte Test Strip. The Dermatophyte Test Strip provides a reliable, convenient and quick method to test for tinea unguium.

Itraconazole (Sporanox®) in superficial and systemic fungal infections

Itraconazole (Sporanox) is a triazole antifungal agent with a broad activity spectrum and favorable pharmacokinetic and safety profiles. Numerous clinical trials have established the efficacy and safety of itraconazole in the treatment of superficial fungal infections. In this field, full exploitation of its pharmacokinetics in keratinized tissues has led to the development of intermittent (pulse) treatment regimens that allow similar efficacy with lower overall drug exposure as well as a reduction in treatment costs. The additional anti-inflammatory action of itraconazole also makes it suitable for application in difficult-to-treat inflammatory skin disorders, such as seborrheic dermatitis. Recently, a new oral liquid formulation and an intravenous formulation have been developed, extending the therapeutic application of itraconazole to systemic fungal infections. Due to its broad activity spectrum and excellent tolerability, itraconazole is a valuable addition to the antifungal armamentarium used for prophylactic and empiric treatment in immunocompromised hosts.

Health-related quality of life in patients with nail disorders

Fingernails and toenails are important organs of our body, serving as protection for the tips of fingers and toes. Fingernails also enhance fine touching and tactile sensitivity, as well as aid in the picking up of small objects. Healthy-looking nails are an important part of an individual's body image, and any nail abnormalities may be considered by patients as a significant cosmetic problem, markedly influencing their self-esteem. However, recent data have indicated that nail lesions are not only important because of cosmetic disfigurement, but may be a symptom of significant morbidity. Severe nail involvement was also shown to negatively impair social functioning and to interfere with work ability, thus markedly influencing a patient's well-being. Based on literature data and our own experience we conclude that nail diseases cause a marked decrease in health-related quality of life in a substantial percentage of patients. Nail changes are an important medical concern for patients and, therefore, nail diseases should raise attention and receive proper care from both physicians and other healthcare providers.

Stigmatisation in onychomycosis patients: a population-based study

Patients with onychomycosis may experience significant psychosocial problems, similarly to other skin diseases. The objectives of this study were to analyse the level of stigmatisation among subjects with onychomycosis and the effect of anti-mycotic therapy on this feeling. This prospective study was carried out among 1684 patients (1050 women and 634 men, mean age 52.2 ± 15.5 years) with onychomycosis. All subjects were asked to fulfil the stigmatisation questionnaire at the baseline visit and after the completion of the anti-mycotic therapy. Stigmatisation level was assessed with reference to gender, age, education, type and duration of onychomycosis and the number of involved nails. Patients with onychomycosis reported markedly increased feeling of stigmatisation. Fingernail involvement was the major variable negatively influencing the stigmatisation level. Female patients and younger ones appeared to be more stigmatised. No significant relationships were found between stigmatisation level and education, number of involved fingernails or toenails, as well as the duration of onychomycosis. The anti-mycotic therapy resulted in significant reduction of all analysed aspects of stigmatisation to about 40% of the baseline level. Onychomycosis should be considered as an important problem for patients, significantly reducing their physical, mental and social well-being, also leading to marked stigmatisation of patients.

Deep fungal dermatitis in three inland bearded dragons (Pogona vitticeps) caused by the Chrysosporium anamorph of Nannizziopsis vriesii

The Chrysosporium anamorph of Nannizziopsis vriesii (CANV), a keratinophilic fungus that naturally and experimentally causes severe and often fatal dermatitis in multiple reptile species, was isolated in pure culture from skin samples of three inland bearded dragons (Pogona vitticeps) with deep granulomatous dermatomycosis. The first animal presented with a focal maxillary swelling involving the skin and gingiva. This lizard died while undergoing itraconazole and topical miconazole therapy. The second presented with focally extensive discoloration and thickening of the skin of the ventrum and was euthanized after 10 weeks of itraconazole therapy. A third lizard presented with hyperkeratotic exudative dermatitis on a markedly swollen forelimb. Amputation and itraconazole therapy resulted in a clinical cure. Histopathology of tissue biopsies in all cases demonstrated granulomatous dermatitis with intralesional hyphae morphologically consistent with those produced by the CANV. The second lizard also had granulomatous hepatitis with intralesional hyphae. Evidence in this report suggests that the CANV is the etiologic agent of an emerging condition in captive bearded dragons that has been called 'yellow fungus disease'.

Evaluation of quality of life in patients with toenail onychomycosis by Polish version of an international onychomycosis-specific questionnaire

BACKGROUND

Onychomycosis is the most frequent nail disease, which could impair the patient's quality of life.

OBJECTIVE

The present study was undertaken to evaluate the impact of toenail onychomycosis on quality of life among Polish population.

PATIENTS AND METHODS

Three thousand nine-hundred and four (3904: 2269 females and 1635 males) individuals fulfilled an international onychomycosis-specific quality-of-life questionnaire consisting of statements regarding social, emotional and symptoms problems. All patients had toenail onychomycosis confirmed by the positive direct microscopic examination and/or by the positive mycologic culture. Seven hundred and sixty-seven patients simultaneously had fingernail onychomycosis. All patients were divided into subgroups according to sex, age, education level, place of living, type of onychomycosis, number of involved toenails, fingernails involvement, duration of illness and previously used antimycotic therapy.

RESULTS

Most of the patients demonstrated significantly reduced quality of life. The degree of life impairment varied between analysed subgroups. Patients with more advanced toenail onychomycosis and with fingernail involvement were more seriously affected. Both social and emotional impairments were more pronounced in female than in male patients, although there were no differences according to symptoms. Moreover, patients with better educational level and people living in towns or cities were more emotionally and socially affected by onychomycosis, although people living in the country or with poorer education level presented with significantly more severe symptoms.

CONCLUSIONS

Toenail onychomycosis is still a serious medical problem, which can significantly reduce the patient's quality of life.
