The prevalence of onychomycosis in patients with chronic renal failure undergoing dialysis: A cross-sectional study. Heliyon 2024; 10:e25737. [PMID: 38434055 PMCID: PMC10906168 DOI: 10.1016/j.heliyon.2024.e25737] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 01/29/2024] [Accepted: 02/01/2024] [Indexed: 03/05/2024] Open
Abstract
Onychomycosis is one of the most common cutaneous symptoms in patients with chronic renal failure. In the present study, we aimed to investigate the prevalence and determine the factors likely associated with developing onychomycosis among dialysis patients. This cross-sectional study was conducted between 2022 and 2023 with 312 chronic renal failure patients undergoing dialysis visiting the dialysis departments of Guilan University of Medical Sciences. Participants were selected by consecutive sampling method. A dermatologist subjected the patients to a detailed clinical assessment of the fingernails and toenails to find evidence of Onychomycosis. Periodic acid-Schiff (PAS) staining was performed in case of suspicion of Onychomycosis. A total of 312 inpatients were investigated during the time frame of the present study. Among study patients, 62.5% were male, the average age of the patients was 59.3 ± 13.9 years, and the mean duration of dialysis was 37.5 ± 38.5 months. A total of 12.8% (n = 40) of patients undergoing dialysis had Onychomycosis. Diabetes mellitus was present in 37.5% of dialysis patients. Diabetes and Onychomycosis were significantly associated, so the prevalence rate of Onychomycosis in diabetic patients was almost twice that of non-diabetic patients (17.9% vs. 9.7%; P < 0.001). Logistic regression analysis revealed that age, sex, education level, and type of dialysis access were the predictors of Onychomycosis development. Onychomycosis puts people at risk for more severe infections, including erysipelas, cellulitis, and amputations; thus, dialysis patients need to learn how to take care of their toenails properly.

Patient Prefer Adherence 2024; 18:475-486. [PMID: 38410773 PMCID: PMC10896105 DOI: 10.2147/ppa.s450215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 02/13/2024] [Indexed: 02/28/2024] Open
Abstract
Background Toenail onychomycosis affects approximately 6.7% of Canadians. Symptoms include nail discolouration/disfiguration and pain; psychosocial impacts contribute to reduced health-related quality-of-life. Comorbid diabetes increases the risk of complications and exacerbates burden. Treatment may include topical therapy and/or oral agents. Purpose To understand toenail onychomycosis treatment preferences, and to quantify the impact of toenail onychomycosis, with or without diabetes, on patient well-being. Methods Adults living in Canada with self-reported, physician-diagnosed, toenail onychomycosis were recruited online. A discrete choice experiment was used to quantify treatment preferences. Scenarios were randomized; data were analyzed using conditional logit regression. Health state utilities were estimated using the Health Utilities Index Mark 3®. Results were stratified by diabetes status and toenail onychomycosis severity; the Wilcoxon Rank Sum test was used to assess between-group utility differences. Results Three-hundred thirteen participants with toenail onychomycosis were included (161 had comorbid diabetes; 61.3%, severe onychomycosis). The mean age was 57.7 years; 55.9% were male. Treatment attributes with statistically significant impacts on patient preferences were efficacy (odds ratio [OR],1.04; 95% confidence interval [CI], 1.02-1.05 per 1% increased treatment success), administration method (one pill versus topical nail lacquer reference, 1.14; 1.04-1.26; topical solution applicator versus reference: 1.15; 1.03-1.29), severe adverse events (0.85; 0.80-0.90 per 1% increased risk), and risk of potential pharmacodynamic (0.80; 0.76-0.85) and alcohol (0.93; 0.88-0.98) interactions; preferences were more pronounced for efficacy and avoiding severe adverse events among toenail onychomycosis patients with comorbid diabetes. The mean (95% CI) utility value was 0.73 (0.70-0.75) overall, and statistically significantly lower (p=0.02) for toenail onychomycosis patients with diabetes (0.70; CI, 0.66-0.73) than those without (0.76; CI, 0.72-0.79). Conclusion Among patients with toenail onychomycosis, the presence of diabetes was associated with differing treatment-related preferences. Utility values for patients with toenail onychomycosis represent a significant decline from full health that is exacerbated by comorbid diabetes.

[PMID: 38099045 PMCID: PMC10718108 DOI: 10.4103/idoj.idoj_642_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 05/19/2023] [Accepted: 05/25/2023] [Indexed: 12/17/2023] Open
Abstract
Background Onychomycosis (OM) is the most common nail disorder accounting for 40-50% of all onychopathies. Onychomycosis is caused by dermatophytes in majority, mostly Trichophyton (T.) rubrum followed by T. mentragrophytes var. interdigitale. However, there is a variation in the etiological profile with the subset of population, time, and geographical location. In immunocompromised hosts, non-dermatophytic molds (NDMs) and yeasts like Candida albicans and Candida parapsilosis are the main causative agents. Diabetes mellitus (DM) is a well-established risk factor for OM. Aim and Objectives This study was conducted to determine the clinical and mycological characteristics of OM in diabetic patients and to evaluate the clinico-etiological correlation, if any. Materials and Methods Three hundred consecutive diabetic patients were screened, of whom 102 (34%) patients were diagnosed with OM based on clinical, mycological, dermoscopic, and histological criteria. Results Distal lateral subungual onychomycosis was the most common clinical variant seen in 80 (78.43%) patients. Fungal culture was positive in 57 (55.88%) of which NDMs constituted approximately half (47.61%) of the isolates, followed by Candida species (30.15%) and dermatophytes (22.22%). The clinico-mycological correlation was performed to look for the association of various fungi with the clinical type of OM. Distal lateral subungual onychomycosis was majorly caused by NDMs (51.02%), followed by Candida species (28.57%), and dermatophytes (20.40%). Conclusion Non-dermatophytic molds are increasingly incriminated as the causative organisms for OM in DM and must be considered as potential pathogens in the present scenario, thus necessitating the change in the treatment options accordingly.

Abstract
Background Though diabetes mellitus (DM) is a well-recognised risk factor for onychomycosis (OM), the epidemiology of OM in diabetic patients remains largely unexplored, especially from the Indian subcontinent. Aims and objectives To estimate the prevalence of OM in diabetic patients, to identify and analyse risk factors, and correlate the severity of nail changes with glycemic control (HBA1c). Methods This cross-sectional, analytical study involved 300 diabetic patients. Patients with the clinical diagnosis of OM, supplanted by at least two of the four tests (KOH, culture, onychoscopy and nail histopathology) were considered cases of OM. Demographic and haematological profile was analysed using chi-square test/ Fischer's exact test. Logistic regression was applied to assess the independent risk factors. Results The prevalence of OM in DM patients was 34% (102/300) and significant risk factors included; age >60 years, male gender, closed shoes, disease duration >5 years, high BMI (>25) and lack of awareness about nail changes. Distal and lateral subungual OM (78%) was the commonest presentation followed by proximal subungual OM, superficial OM and total dystrophic OM. Correlation between HbA1c and the number of nails involved was found to be significant. Limitation As cases were recruited from a hospital setting, there could be chances of Berksonian bias. Conclusion The prevalence of OM in diabetic patients is high and the severity of nail changes correlates with HbA1C levels. It is important to diagnose OM early in order to treat and prevent complications.

Abstract
BACKGROUND A systematic review was conducted to investigate the prevalence of onychomycosis in patients with diabetes. The association of onychomycosis with risk factors in patients with diabetic foot syndrome was also examined. METHODS The recommendations in the preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist were applied, and the included studies were assessed using the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) method. Searches were conducted in October 2022 using PubMed (Medline) and Scopus for clinical studies, clinical trials, comparative studies, observational studies, and randomised clinical trials or controlled clinical trials addressing the prevalence and consequences of onychomycosis in patients with diabetes, diagnoses or treatments. Two authors performed the study selection and data extraction, and any discrepancies between the two reviewers were resolved through discussion with a third reviewer. RESULTS The systematic review included ten studies that met the inclusion criteria, and these studies enrolled 5664 patients with diabetes. Among these patients, 29.18% had onychomycosis that was mainly caused by Trichophyton rubrum. A significant association was found between the occurrence of onychomycosis and the presence of diabetic neuropathy (p = .012) and elevated glycosylated haemoglobin values (p = .039). There was no significant association between onychomycosis and ulceration (p = .185). Eight studies had a grade 4 level of evidence and a grade C recommendation, and one study had a grade 1b level of evidence and a grade A recommendation. CONCLUSION The information described in the literature is insufficient and heterogeneous regarding the association of risk factors and ulceration in patients with diabetic foot compared with developing onychomycosis. There is also a need to implement onychomycosis diagnostic testing instead of relying only on a clinical diagnosis. Additional prospective, randomised, comparative studies are needed to increase the quality of studies in the literature.

Abstract
This study aimed to determine the prevalence of onychomycosis and interdigital tinea pedis in a cohort of Spanish patients with diabetes in whom onychomycosis was clinically suspected (n = 101). Samples from a first toenail scraping and the fourth toe clefts were subjected to potassium hydroxide direct vision and incubated in Sabouraud and dermatophyte test medium. Fifty-eight samples were also analyzed by a pathologist using periodic acid-Schiff staining and Calcofluor white direct fluorescence microscopy. Onychomycosis was only confirmed in 41 patients (40.6%). The most frequent aetiological agent was Trichophyton rubrum, isolated in 10 patients (36%), followed by Candida parapsilosis in 7 patients (25%). Tests on the fourth toe cleft samples were only positive in 11 patients (10.9%), and in all cases, onychomycosis was also diagnosed. Neuroischemic foot was the only significant variable associated with onychomycosis in the univariate analysis (P < .01). A positive result for mycosis in the fourth toe cleft was found in 11 cases (10.9%) and was associated with a history of myocardial infarction (P< .01; odds ratio [OR]: 84.2, confidence interval [CI]: 6.8-1036.4) and neuroischemic foot (P< .01; OR: 13.7, CI: 12.6-71.6) in the multivariate model. In conclusion, the prevalence of onychomycosis and tinea pedis in patients with diabetes in whom onychomycosis was clinically suspected was 40.6% and 10.9%, respectively. In addition, onychomycosis was not always associated with tinea pedis. These results show that clinical diagnosis has low accuracy in people with diabetes mellitus, and that diagnosis should not be based on clinical toenail characteristics alone.

Abstract
Objective: To provide an overview of onychomycosis and current treatments and to identify opportunities for pharmacy technicians to improve treatment outcomes. Data Sources: A MEDLINE/PubMed search (1966 to October 2018) was performed using search terms designed to identify English-language articles on onychomycosis diagnosis, treatment, and prevention, as well as articles on the impact of pharmacy technicians on onychomycosis outcomes and the use of pharmacy technicians to improve treatment adherence. Study Selection and Data Extraction: Review articles and clinical studies describing onychomycosis, risk factors, treatment efficacy, and prevention of recurrent infections were included. Data Synthesis: Although no articles on the impact of pharmacy technicians in the treatment of onychomycosis were found, the importance of treatment adherence on positive outcomes highlights a potential role of pharmacy technicians. Pharmacy technicians can identify patients with potential onychomycosis based on questions about over-the-counter products and refer patients to the pharmacist for counseling on treatment. Pharmacy technicians can also reinforce treatment adherence at refill visits. Conclusions: Pharmacy technicians can have a positive impact on onychomycosis treatment outcomes by addressing barriers to successful treatment and promoting treatment adherence.

Abstract
Onychomycosis is a fungal nail infection caused by dermatophytes, non-dermatophyte molds, and yeasts. Treatment of this infection can be difficult, with relapse likely to occur within 2.5 years of cure. The objective of this article is to review factors that can impact cure and to suggest practical techniques that physicians can use to maximize cure rates. Co-morbidities, as well as disease severity and duration, are among the many patient factors that could influence the efficacy of antifungal therapies. Furthermore, organism, treatment, and environmental factors that may hinder cure include point mutations, biofilms, affinity for non-target enzymes, and exposure to fungal reservoirs. To address patient-related factors, physicians are encouraged to conduct confirmatory testing and treat co-morbidities such as tinea pedis early and completely. To combat organism-focused factors, it is recommended that disruption of biofilms is considered, and drugs with multiple routes of delivery and unique mechanisms of action are prescribed when traditional agents are not effective. Extending follow-up periods, using combination treatments, and considering pulse regimens may also be of benefit. Through these practical techniques, physicians can maximize cure and limit the risk of relapse and re-infection.

Abstract
Onychomycosis is a fungal nail infection caused by dermatophytes, nondermatophyte molds, and yeasts. This difficult-to-treat chronic infection has a tendency to relapse despite treatment. This paper aims to offer a global perspective on onychomycosis management from expert physicians from around the world. Overall, the majority of experts surveyed used systemic, topical, and combination treatments approved in their countries and monitored patients based on the product insert or government recommendations. Although the basics of treating onychomycosis were similar between countries, slight differences in onychomycosis management between countries were found. These differences were mainly due to different approaches to adjunctive therapy, rating the severity of disease and use of prophylaxis treatment. A global perspective on the treatment of onychomycosis provides a framework of success for the committed clinician with appreciation of how onychomycosis is managed worldwide.

Abstract
OBJECTIVES To examine the correlations between elements of feet-washing behavior, presence of tinea pedis (TP), and patients' background characteristics in order to identify a concrete intervention method to prevent TP. DESIGN AND PARTICIPANTS A cross-sectional study of 30 patients with diabetes (16 with TP) who were admitted to or visited the university hospital. MAIN OUTCOME MEASURES The presence of TP was confirmed by the detection of dermatophytes by direct microscopy. Data on elements of feet-washing behavior, such as scrubbing between the toes, were collected by observing recorded videos of participants normally washing their feet as they do at home. The patients' background characteristics included demographic data; diabetes-related factors; patient knowledge regarding diabetes, foot problems, and TP prevention; purpose for feet washing; and any difficulties in feet washing. MAIN RESULTS The number of times patients scrubbed between their toes while washing with soap was significantly lower in patients with TP (odds ratio, 0.95; P = .036; with a cutoff value of 35 times) and those who had difficulty in reaching their feet with their hands (B = -14.42, P = .041). CONCLUSIONS An effective foot-washing protocol should include specific instructions for patients to scrub between their toes at least 35 times in all 8 spaces while washing with soap. Appropriate advice is also needed for individuals who have difficulty reaching their feet with their hands. Education about appropriate foot-washing behavior may potentially prevent TP.

Abstract
BACKGROUND Fungal infection of the toenails, also called onychomycosis, is a common problem that causes damage to the nail's structure and physical appearance. For those severely affected, it can interfere with normal daily activities. Treatment is taken orally or applied topically; however, traditionally topical treatments have low success rates due to the nail's physical properties. Oral treatments also appear to have shorter treatment times and better cure rates. Our review will assist those needing to make an evidence-based choice for treatment. OBJECTIVES To assess the effects of oral antifungal treatments for toenail onychomycosis. SEARCH METHODS We searched the following databases up to October 2016: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers and checked the reference lists of included and excluded studies for further references to relevant randomised controlled trials (RCTs). We sought to identify unpublished and ongoing trials by correspondence with authors and by contacting relevant pharmaceutical companies. SELECTION CRITERIA RCTs comparing oral antifungal treatment to placebo or another oral antifungal treatment in participants with toenail onychomycosis, confirmed by one or more positive cultures, direct microscopy of fungal elements, or histological examination of the nail. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included 48 studies involving 10,200 participants. Half the studies took place in more than one centre and were conducted in outpatient dermatology settings. The participants mainly had subungual fungal infection of the toenails. Study duration ranged from 4 months to 2 years.We assessed one study as being at low risk of bias in all domains and 18 studies as being at high risk of bias in at least one domain. The most common high-risk domain was 'blinding of personnel and participants'.We found high-quality evidence that terbinafine is more effective than placebo for achieving clinical cure (risk ratio (RR) 6.00, 95% confidence interval (CI) 3.96 to 9.08, 8 studies, 1006 participants) and mycological cure (RR 4.53, 95% CI 2.47 to 8.33, 8 studies, 1006 participants). Adverse events amongst terbinafine-treated participants included gastrointestinal symptoms, infections, and headache, but there was probably no significant difference in their risk between the groups (RR 1.13, 95% CI 0.87 to 1.47, 4 studies, 399 participants, moderate-quality evidence).There was high-quality evidence that azoles were more effective than placebo for achieving clinical cure (RR 22.18, 95% CI 12.63 to 38.95, 9 studies, 3440 participants) and mycological cure (RR 5.86, 95% CI 3.23 to 10.62, 9 studies, 3440 participants). There were slightly more adverse events in the azole group (the most common being headache, flu-like symptoms, and nausea), but the difference was probably not significant (RR 1.04, 95% CI 0.97 to 1.12; 9 studies, 3441 participants, moderate-quality evidence).Terbinafine and azoles may lower the recurrence rate when compared, individually, to placebo (RR 0.05, 95% CI 0.01 to 0.38, 1 study, 35 participants; RR 0.55, 95% CI 0.29 to 1.07, 1 study, 26 participants, respectively; both low-quality evidence).There is moderate-quality evidence that terbinafine was probably more effective than azoles for achieving clinical cure (RR 0.82, 95% CI 0.72 to 0.95, 15 studies, 2168 participants) and mycological cure (RR 0.77, 95% CI 0.68 to 0.88, 17 studies, 2544 participants). There was probably no difference in the risk of adverse events (RR 1.00, 95% CI 0.86 to 1.17; 9 studies, 1762 participants, moderate-quality evidence) between the two groups, and there may be no difference in recurrence rate (RR 1.11, 95% CI 0.68 to 1.79, 5 studies, 282 participants, low-quality evidence). Common adverse events in both groups included headache, viral infection, and nausea.Moderate-quality evidence shows that azoles and griseofulvin probably had similar efficacy for achieving clinical cure (RR 0.94, 95% CI 0.45 to 1.96, 5 studies, 222 participants) and mycological cure (RR 0.87, 95% CI 0.50 to 1.51, 5 studies, 222 participants). However, the risk of adverse events was probably higher in the griseofulvin group (RR 2.41, 95% CI 1.56 to 3.73, 2 studies, 143 participants, moderate-quality evidence), with the most common being gastrointestinal disturbance and allergic reaction (in griseofulvin-treated participants) along with nausea and vomiting (in azole-treated participants). Very low-quality evidence means we are uncertain about this comparison's impact on recurrence rate (RR 4.00, 0.26 to 61.76, 1 study, 7 participants).There is low-quality evidence that terbinafine may be more effective than griseofulvin in terms of clinical cure (RR 0.32, 95% CI 0.14 to 0.72, 4 studies, 270 participants) and mycological cure (RR 0.64, 95% CI 0.46 to 0.90, 5 studies, 465 participants), and griseofulvin was associated with a higher risk of adverse events, although this was based on low-quality evidence (RR 2.09, 95% CI 1.15 to 3.82, 2 studies, 100 participants). Common adverse events included headache and stomach problems (in griseofulvin-treated participants) as well as taste loss and nausea (in terbinafine-treated participants). No studies addressed recurrence rate for this comparison.No study addressed quality of life. AUTHORS' CONCLUSIONS We found high-quality evidence that compared to placebo, terbinafine and azoles are effective treatments for the mycological and clinical cure of onychomycosis, with moderate-quality evidence of excess harm. However, terbinafine probably leads to better cure rates than azoles with the same risk of adverse events (moderate-quality evidence).Azole and griseofulvin were shown to probably have a similar effect on cure, but more adverse events appeared to occur with the latter (moderate-quality evidence). Terbinafine may improve cure and be associated with fewer adverse effects when compared to griseofulvin (low-quality evidence).Only four comparisons assessed recurrence rate: low-quality evidence found that terbinafine or azoles may lower the recurrence rate when compared to placebo, but there may be no difference between them.Only a limited number of studies reported adverse events, and the severity of the events was not taken into account.Overall, the quality of the evidence varied widely from high to very low depending on the outcome and comparison. The main reasons to downgrade evidence were limitations in study design, such as unclear allocation concealment and randomisation as well as lack of blinding.

Abstract
Background: Diabetic patients are more susceptible to cutaneous fungal infections. The higher blood sugar levels cause increasing the cutaneous fungal infections in these patients. The main objective of this study was to find the frequency of fungal infections among cutaneous lesions of diabetic patients and to investigate azole antifungal agent susceptibility of the isolates. Materials and Methods: In this study, type 1diabetes (n = 78) and type 2 diabetes (n = 44) comprised 47 cases (38.5%) with diabetic foot ulcers and 75 cases (61.5%) with skin and nail lesions were studied. Fungal infection was confirmed by direct examination and culture methods. Antifungal susceptibility testing by broth microdilution method was performed according to the CLSI M27-A and M38-A references. Results: Out of 122 diabetic patients, thirty (24.5%) were affected with fungal infections. Frequency of fungal infection was 19.1% in patients with diabetic foot ulcer and 28% of patients with skin and nail lesions. Candida albicans and Aspergillus flavus were the most common species isolated from thirty patients with fungal infection, respectively. Susceptibility testing carried out on 18 representative isolates (13 C. albicans, five C. glabrata) revealed that 12 isolates (10 C. albicans and two C. glabrata isolates) (66.6%) were resistant (minimum inhibitory concentration [MIC] ≥64 mg/ml) to fluconazole (FCZ). Likewise, eight isolates (80%) of Aspergillus spp. were resistant (MIC ≥4 mg/ml), to itraconazole. Conclusion: Our finding expands current knowledge about the frequency of fungal infections in diabetic patients. We noted the high prevalence of FCZ-resistant Candida spp., particularly in diabetic foot ulcers. More attention is important in diabetic centers about this neglected issue.

Abstract
INTRODUCTION Approximately, 33% patients with diabetes are afflicted with onychomycosis. In the past, nondermatophyte molds have been regarded as opportunistic pathogens; recently, Aspergillus species are considered as emerging pathogens of toenail infections. In Sri Lanka, the prevalence of Aspergillus species in onychomycosis among diabetics is not well documented. OBJECTIVE To determine the proportion of Aspergillus onychomycosis, risk factors and knowledge among diabetics. MATERIALS AND METHODS This was descriptive cross-sectional study. Three hundred diabetic patients were included. Clinical examinations of patients' toenails were performed by a clinical microbiologist. Laboratory identification was done, and pathogens were identified to the species level by morpho-physiological methods. All inferential statistics were tested at P < 0.05. RESULTS Among clinically suspected patients, 85% (255/300) were mycologically confirmed to have onychomycosis. Aspergillus species were most commonly isolated n = 180 (71%) followed by dermatophytes, yeasts, and other molds n = 75 (29%). Of the patients having Aspergillus onychomycosis, 149 (83%) were in the > age group. In men, Aspergillus onycomycosis was seen in 82%. Among patients who had Aspergillus nail infection, 114 (63%) had diabetes for a period of > years. Among patients who were engaged in agricultural activities, 77% were confirmed to have infected nails due to Aspergillus species. CONCLUSION Aspergillus niger was the most common pathogen isolated from toenail infection. Aspergillus species should be considered as an important pathogen in toenail onychomycosis in diabetic patients. Risk factors associated with Aspergillus onychomycosis were age, gender, duration of diabetes, length of exposure to fungi, and occupation.

Abstract
Background Onychomycosis has several clinical presentations and is caused by various infectious organisms. Objective To provide guidance for selection of appropriate treatment. Methods The literature on onychomycosis management was reviewed to generate an evidence-based decision tree. Results and Conclusion Several options are available: terbinafine, itraconazole, fluconazole, ciclopirox 8% nail lacquer, efinaconazole 10% nail solution, and laser therapy. Further studies on lasers are needed before use can be recommended. Nondermatophyte molds or mixed infection can be managed with terbinafine or itraconazole with or without topicals. Itraconazole, fluconazole, and efinaconazole can be used for Candida infection. For dermatophytes, topicals can be considered for mild to moderate onychomycosis. For moderate to severe cases, any oral monotherapy can be used; however, we suggest terbinafine if there is a possibility of a drug interaction. These recommendations can be applied for all ages, immune function, or metabolic status, but proper monitoring and contraindications should be taken into consideration.

Abstract
INTRODUCTION Diabetic foot ulcers, especially when they become infected, are a leading cause of morbidity and may lead to severe consequences, such as amputation. Optimal treatment of these diabetic foot problems usually requires a multidisciplinary approach, typically including wound debridement, pressure off-loading, glycemic control, surgical interventions and occasionally other adjunctive measures. AREAS COVERED Antibiotic therapy is required for most clinically infected wounds, but not for uninfected ulcers. Unfortunately, clinicians often prescribe antibiotics when they are not indicated, and even when indicated the regimen is frequently broader spectrum than needed and given for longer than necessary. Many agents are available for intravenous, oral or topical therapy, but no single antibiotic or combination is optimal. Overuse of antibiotics has negative effects for the patient, the health care system and society. Unnecessary antibiotic therapy further promotes the problem of antibiotic resistance. EXPERT OPINION The rationale for prescribing topical, oral or parenteral antibiotics for patients with a diabetic foot wound is to treat clinically evident infection. Available published evidence suggests that there is no reason to prescribe antibiotic therapy for an uninfected foot wound as either prophylaxis against infection or in the hope that it will hasten healing of the wound.

Abstract
Tinea pedis (TP) may lead to the development of foot ulcers in diabetic patients; thus, its prevention in diabetic patients is important. TP occurs after dermatophytes on the skin scales of TP patients attach to the feet. Therefore, it is necessary to remove the scales and dermatophytes, and this can be performed using various methods, including foot washing. This study aimed to objectively examine the association between the presence of TP and foot-washing habits. We included 33 diabetic patients, and, of these, 17 had TP. The presence of washing residue on the feet was determined by applying a fluorescent cream to the participants' feet, and images of the feet were captured under ultraviolet light before and after foot washing. Our results showed that diabetic patients with TP had higher levels of washing residue on their feet than those without TP. The importance of washing feet to prevent TP needs to be emphasized through educational programs for diabetic patients. Furthermore, the development of an effective foot-washing technique is essential.

Abstract
Les infections mycosiques du pied constituent un motif fréquent de consultation chez les diabétiques, le diabète constituant à la fois un facteur favorisant et aggravant les lésions cutanéomuqueuses. L'objectif de ce travail était d'identifier la flore mycologique locale responsable des lésions du pied chez le diabétique et déterminer les facteurs favorisant la survenue de mycoses. Il s'agissait d'une étude transversale intéressant des diabétiques suivis en consultation; un prélèvement mycologique, avec examen direct et culture, a été réalisé devant toute suspicion clinique de lésion mycosique. Quatre-vingt-deux patients ont été inclus. L'hémoglobine glycosylée moyenne a été de9,2% ± 2,23. Un intertrigo inter orteil a été noté dans 90,2% des cas; l'examen mycologique était positif dans 64,8% des cas, avec 18 cas de Trichophyton rubrum et 11 cas de Candida albicans. Une atteinte unguéale a été suspectée chez 65,9% patients; la culture a mis en évidence un Trichosporon pathogène chez sept patients, un Candida albicansdans six cas, un Trichophyton rubrum dans quatre cas, avec trois cas de Trichophyton mentagrophytes et deux cas de Scytalidium dimidiatum. L’étude analytique, après confirmation mycologique, en fonction des principales caractéristiques des patients a montré que l'atteinte mycosique du pied est significativement corrélée au déséquilibre glycémique. Ce travail a montré la prédominance du Trichophyton rubrum dans les lésions d'intertrigo inter orteil et du Trichosporon dans les onychomycoses, avec une prédominance globale plus globale plus élevée du TR.

Abstract
INTRODUCTION Onychomycosis causes approximately one-half of all nail disorders and its prevalence has been steadily increasing. It is difficult to treat, partly due to the subungual location and the inability of both oral and topical antifungals to reach the site of infection. Published cure rates with oral drugs are < 50% and even lower with topical drugs. Pathogenic factors include the diversity of fungal organisms and the difficulty of drugs penetrating the nail plate. Tavaborole is a broad-spectrum oxaborole antifungal agent with low molecular weight, permitting optimal nail plate penetration. In vitro and ex vivo studies have demonstrated the superior nail-penetrating properties of tavaborole compared to existing topical antifungal medications approved for the treatment of onychomycosis. AREAS COVERED The clinical characteristics and prevalence of onychomycosis, currently available treatments, and the chemistry, safety and pharmacokinetic properties of tavaborole for the treatment of onychomycosis. EXPERT OPINION Tavaborole is a novel, topical antifungal pharmaceutical agent pending FDA approval for the treatment of toenail onychomycosis due to dermatophytes. Efficacy has been demonstrated by a clinical development program including in vitro data and two large Phase III trials that enrolled ∼ 1200 patients. When approved, tavaborole topical solution, 5% may become a safe and effective option for the treatment of onychomycosis.

Abstract
Onychomycosis describes a chronic fungal infection of the nails most frequently caused by dermatophytes, primarily Trichophyton rubrum. In addition, yeasts (e. g. Candida parapsilosis), more rarely molds (Scopulariopsis brevicaulis), play a role as causative agents of onychomycosis. However, in every case it has to be decided if these yeasts and molds are contaminants, or if they are growing secondarily on pathological altered nails. The point prevalence of onychomycosis in Germany is 12.4%, as demonstrated within the "Foot-Check-Study", which was a part of the European Achilles project. Although, onychomycosis is rarely diagnosed in children and teens, now an increase of fungal nail infections has been observed in childhood. More and more, diabetes mellitus becomes important as significant disposing factor both for tinea pedis and onychomycosis. By implication, the onychomycosis represents an independent and important predictor for development of diabetic foot syndrome and foot ulcer. When considering onychomycosis, a number of infectious and non-infectious nail changes must be excluded. While psoriasis of the nails does not represent a specific risk factor for onychomycosis, yeasts and molds are increasing isolated from patients with psoriatic nail involvement. In most cases this represents secondary growth of fungi on psoriatic nails. Recently, stigmatization and impairment of quality of life due to the onychomycosis has been proven.

Abstract
The skin should not be considered as an isolated organ but rather as a definite functioning system that communicates with the internal environment. Skin signs of systemic diseases occur frequently and sometimes feature the first symptoms of an internal disease; furthermore, these manifestations may be the sole expressions of otherwise asymptomatic systemic disorders. A number of dermatologic signs, symptoms, and disorders can be invaluable as markers of systemic disease. Although a plethora of specialized modern diagnostic tests are available, the skin still remains the only organ of the body that is immediately and completely accessible to direct clinical examination. This contribution reviews the skin signs of systemic diseases. The description of the clinical features of skin lesions observed in several internal diseases will be useful to general physicians, internists, and dermatologists in the diagnosis of a systemic disease.

[PMID: 22136082 PMCID: PMC3248359 DOI: 10.1186/1757-1146-4-26] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2011] [Accepted: 12/04/2011] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Effective treatment of tinea pedis and onychomycosis is crucial for patients with diabetes as these infections may lead to foot ulcers and secondary bacterial infections resulting in eventual lower limb amputation. Although numerous studies have assessed the effectiveness of antifungal drug and treatment regimens, most exclude patients with diabetes and examine otherwise healthy individuals. While these studies are useful, results cannot necessarily be extrapolated to patients with diabetes. The purpose of this study was to therefore identify the best evidence-based treatment interventions for tinea pedis or onychomycosis in people with diabetes. METHODS The question for this systemic review was: 'what evidence is there for the safety and/or efficacy of all treatment interventions for adults with tinea pedis and/or onychomycosis in people with diabetes'? A systematic literature search of four electronic databases (Scopus, EbscoHost, Ovid, Web of Science) was undertaken (6/1/11). The primary outcome measure for safety was self-reported adverse events likely to be drug-related, while the primary outcome measures assessed for 'efficacy' were mycological, clinical and complete cure. RESULTS The systematic review identified six studies that examined the safety and/or efficacy of treatment interventions for onychomycosis in people with diabetes. No studies were identified that examined treatment for tinea pedis. Of the studies identified, two were randomised controlled trials (RCTs) and four were case series. Based on the best available evidence identified, it can be suggested that oral terbinafine is as safe and effective as oral itraconazole therapy for the treatment of onychomycosis in people with diabetes. However, efficacy results were found to be poor. CONCLUSIONS This review indicates that there is good evidence (Level II) to suggest oral terbinafine is as safe and effective as itraconazole therapy for the treatment of onychomycosis in people with diabetes. Further research is needed to establish the evidence for other treatment modalities and treatment for tinea pedis for people with diabetes. Future efforts are needed to improve the efficacy of treatment intervention.

Abstract
Diabetic wounds remain a major medical challenge with often disappointing outcomes despite the best available care. An impaired response to tissue hypoxia and insufficient angiogenesis are major factors responsible for poor healing in diabetic wounds. Here we show that the antimycotic drug ciclopirox olamine (CPX) can induce therapeutic angiogenesis in diabetic wounds. Treatment with CPX in vitro led to upregulation of multiple angiogenic genes and increased availability of HIF-1α. Using an excisional wound splinting model in diabetic mice, we showed that serial topical treatment with CPX enhanced wound healing compared to vehicle control treatment, with significantly accelerated wound closure, increased angiogenesis, and increased dermal cellularity. These findings offer a promising new topical pharmacologic therapy for the treatment of diabetic wounds.

Activity of TDT 067 (terbinafine in Transfersome) against agents of onychomycosis, as determined by minimum inhibitory and fungicidal concentrations. J Clin Microbiol 2011; 49:1716-20.

Abstract
TDT 067 is a novel carrier-based dosage form (liquid spray) of 15 mg/ml of terbinafine in Transfersome that has been developed to deliver terbinafine to the nail bed to treat onychomycosis. In this study, we report the in vitro activities of TDT 067 against dermatophytes, compared with those of the Transfersome vehicle, naked terbinafine, and commercially available terbinafine (1%) spray. The MICs of TDT 067 and comparators against 25 clinical strains each of Trichophyton rubrum, T. mentagrophytes, and Epidermophyton floccosum were determined according to the CLSI M38-A2 susceptibility method (2008). Minimum fungicidal concentrations (MFCs) were determined by subculturing visibly clear wells from the MIC microtiter plates. TDT 067 demonstrated potent activity against the dermatophyte strains tested, with an MIC range of 0.00003 to 0.015 μg/ml. Overall, TDT 067 MIC(50) values (defined as the lowest concentrations to inhibit 50% of the strains tested) were 8-fold and 60-fold lower than those of naked terbinafine and terbinafine spray, respectively. The Transfersome vehicle showed minimal inhibitory activity. TDT 067 demonstrated lower MFC values for T. rubrum and E. floccosum than naked terbinafine and terbinafine spray. TDT 067 has more potent antifungal activity against dermatophytes that cause nail infection than conventional terbinafine preparations. The Transfersome vehicle appears to potentiate the antifungal activity of terbinafine. Clinical investigation of TDT 067 for the topical treatment of onychomycosis is warranted.

Factors associated with presence and severity of toenail onychomycosis in patients with diabetes: a cross-sectional study. Int J Nurs Stud 2011; 48:1101-8. [PMID: 21367414 DOI: 10.1016/j.ijnurstu.2011.02.005] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2010] [Revised: 02/02/2011] [Accepted: 02/05/2011] [Indexed: 01/18/2023]
Abstract
OBJECTIVE To identify the factors associated with toenail onychomycosis in patients with diabetes. METHODS In this cross-sectional, observational study, the presence and severity (area of nail involvement and nail thickness) of toenail onychomycosis and related factors were examined. One hundred and thirteen patients with diabetes were surveyed at the Diabetic Foot Outpatient Clinic at the University hospital. Toenails of all patients enrolled in the survey were examined whether onychomycosis was present or absent by mycological examination. The severity of onychomycosis was assessed by clinical evaluation, using the area of nail involvement and the nail thickness. RESULTS Fifty eight (51.3%) patients had toenail onychomycosis. The presence of onychomycosis was significantly associated with not washing of feet every day (the unadjusted model, OR: 3.45, 95% CI: 1.24-9.65, P=0.018). The median area of nail involvement was 50.0% (range 5.0-100.0%). A larger area of involvement was significantly related to a lower toe brachial index (β=-67.46, P=0.040). The median nail thickness with onychomycosis was 1.14 mm (range 0.68-9.86 mm). Increasing thickness was significantly correlated with higher hemoglobin A(1)c levels (β=0.98, P=0.003). CONCLUSIONS This study suggested that daily washing of feet may reduce the risk of onychomycosis in patients with diabetes. This suggested that education regarding the importance of the washing of feet every day and support for continuous self-care might be effective in the prevention of onychomycosis in patients with diabetes. Furthermore, good control of blood glucose might prevent increasing nail thickness. This study may highlight importance of early nursing educational intervention to improve patients' daily life style for prevention of onychomycosis induced diabetic foot ulcers.
