Pulse itraconazole vs. continuous terbinafine for the treatment of dermatophyte toenail onychomycosis in patients with diabetes mellitus.

BACKGROUND: Oral terbinafine and oral itraconazole are two of the most common agents used for the treatment of toenail dermatophyte onychomycosis. Despite the fact that diabetic patients are more likely to have onychomycosis than normal individuals are, there is little research into the efficacy of standard oral regimens of terbinafine and itraconazole for onychomycosis in the diabetic population. STUDY DESIGN: We present a prospective, randomized, single-blind, parallel group, comparator-controlled, multi-centre study designed to assess the efficacy of the pulse itraconazole (200 mg twice daily, 1 week on, 3 weeks off, for 12 weeks) vs. continuous terbinafine (250 mg once daily for 12 weeks) oral therapies in the treatment of dermatophyte toenail distal and lateral subungual onychomycosis (DLSO) in the diabetic population. EFFICACY PARAMETERS: Primary efficacy measures included mycological cure rate (negative KOH and culture) and effective cure (mycological cure plus nail plate involvement of 10% or less) at Week 48. RESULTS: At Week 48, mycological cure was attained by 88.2% (30 of 34) and 79.3% (23 of 29) of patients in the itraconazole and terbinafine groups, respectively (P not significant). Effective cure (mycological cure with <or=10% of nail plate involvement) was attained by 52.9% (18 of 34) of the itraconazole group and 51.7% (15 of 29) of the terbinafine group (P not significant). Three itraconazole patients experienced side effects in the form of gastrointestinal problems. There were no serious adverse events and no interactions with concomitant medications recorded. DISCUSSION: Both continuous terbinafine and itraconazole pulse therapy are effective and safe in the management of dermatophyte toenail onychomycosis in people with diabetes.

Moisturizers: what they are and a practical approach to product selection.

Moisturizers are widely used products that are important in many dermatologic and cosmetic skin therapies. They contain varying combinations of emollients, occlusives, and humectants to achieve their beneficial effects, and there is an overwhelming number of formulations available. To develop a rational approach for prescribing moisturizers, commercially available products can be categorized on the basis of application site.

Itraconazole and terbinafine treatment of some nondermatophyte molds causing onychomycosis of the toes and a review of the literature.

BACKGROUND: Onychomycosis may be caused by dermatophytes (which form the majority of organisms), Candida species, and nondermatophyte molds. OBJECTIVE: To evaluate the efficacy and safety of itraconazole and terbinafine in the treatment of some nondermatophyte molds that cause toe onychomycosis and to review the literature on the treatment of nondermatophyte mold toe onychomycosis using the oral antifungal agents. PATIENTS AND METHODS: Patients with nondermatophyte mold toe onychomycosis were treated in an open, prospective manner with either itraconazole (pulse) or terbinafine therapy. In each instance, light microscopic examination was consistent with the diagnosis of a nondermatophyte mold. For each patient, mycological evaluation of the target nail resulted in 3 or more successive cultures yielding growth of the mold alone. RESULTS: All 15 patients had onychomycosis of the toes which was of the distal and lateral type. The patients were treated with itraconazole given as the standard 3 pulses with additional pulses administered depending upon the response exhibited by the toe onychomycosis in the patient. Similarly, terbinafine was given for 12 weeks with additional therapy administered as dictated by the response. Efficacy parameters were mycological cure (MC) and clinical cure (CC). Mycological cure was negative light microscopic examination (KOH) and culture. Clinical cure was the appearance of a completely normal-looking nail. At month 12 from the start of treatment, the response was as follows: Scopulariopsis brevicaulis: itraconazole (MC 4/4, CC 2/4) and terbinafine (MC 0/1, CC 0/1), Fusarium species: itraconazole (MC 1/1, CC 1/1) and terbinafine (MC 0/1, CC 0/1), Aspergillus species: itraconazole (MC 5/6, CC 3/6), Alternaria alternata: itraconazole (MC 0/1,CC 0/1), and Onychocola canadensis: itraconazole (MC 1/1, CC 0/1). There were no significant clinical or laboratory adverse effects. CONCLUSIONS: In the present series itraconazole demonstrated efficacy against onychomycosis of the toenails caused by S. brevicaulis and Aspergillus species. A review of the literature confirms our experience with itraconazole and further suggests that terbinafine may also demonstrate efficacy against cases of S. brevicaulis and Aspergillus toe onychomycosis. Additionally, reports in the literature suggest that pedal onychomycosis caused by Fusarium species may also show response to itraconazole and terbinafine. For the other species, there are fewer data, making it difficult to draw conclusions.

Single-blind, randomized, prospective study of sequential itraconazole and terbinafine pulse compared with terbinafine pulse for the treatment of toenail onychomycosis.

OBJECTIVE: Efficacy and safety of sequential pulse therapy with itraconazole and terbinafine were compared with pulse terbinafine alone in the treatment of toenail onychomycosis. METHODS: This was a 72-week prospective, single-blind, randomized, multicenter, comparative, parallel group, nonindustry-sponsored trial. A total of 190 patients were recruited from 3 outpatient dermatology offices in North America. Patients were at least 18 years old and had a clinical and mycologic diagnosis of dermatophyte toenail onychomycosis. Patients were randomly assigned to receive sequential pulse therapy (IIT) with 2 pulses of itraconazole followed by 1 or 2 pulses of terbinafine (itraconazole pulse is 200 mg twice daily for 1 week and terbinafine pulse is 250 mg twice daily for 1 week) versus 3 or 4 pulses of terbinafine (TTT). Main outcome measures at week 72 evaluated mycologic cure rate (negative light microscopy and culture), clinical cure (nail appears completely or totally normal), complete cure (clinical and mycologic cure), and effective therapy (mycologic cure and clinical response with at least 5 mm of new, uninvolved nail growth). RESULTS: At week 72, in the IIT versus TTT groups, the mycologic cure rate was 54 of 75 (72.0%) versus 44 of 90 (48.9%), clinical cure rate was 42 of 75 (56.0%) versus 35 of 90 (38.9%), effective therapy 49 of 75 (65.3%) versus 41 of 90 (45.6%), and complete cure 39 of 75 (52.0%) versus 29 of 90 (32.2%), respectively. Both regimens were well tolerated with no new adverse effects being identified. The rate of permanent discontinuation of therapy because of adverse effects was 2 of 81 (2.5%) with IIT and 2 of 95 (2.1%) with TTT. Each of the adverse effects normalized over time. The number of patients who reported an adverse effect in the 2 groups was 12 of 81 (14.8%) versus 22 of 95 (23.2%), respectively. All these adverse effects were reversible and mild to moderate in severity. CONCLUSION: Sequential pulse therapy with itraconazole and terbinafine is effective and safe for the treatment of dermatophyte toenail onychomycosis.

Single-blind, randomized, prospective study on terbinafine and itraconazole for treatment of dermatophyte toenail onychomycosis in the elderly.

BACKGROUND: The 2 most common agents used to treat dermatophyte onychomycosis of the toe are terbinafine (continuous) and itraconazole (pulse). Although comparative studies have been performed evaluating the efficacy of these 2 agents in adults, no such studies have been reported specifically in the elderly subset. OBJECTIVE: This prospective, randomized, single-blind, non--industry-sponsored, comparative study evaluated the efficacy and safety of terbinafine (continuous) and itraconazole (pulse) therapies in the treatment of dermatophyte onychomycosis of the toe in the elderly population. METHODS: Elderly patients (> or =60 years old) with dermatophyte onychomycosis of at least 1 great toe were randomly assigned to receive either terbinafine 250 mg/day for 12 weeks or itraconazole (pulse) 200 mg twice a day for 1 week, given for 3 pulses. At month 6 from the start of therapy, if there was less than 50% reduction in the affected nail plate area compared with baseline, or if there was less than 3 mm outgrowth of unaffected nail plate as measured in midline, then patients who had been administered terbinafine (continuous) therapy were given an extra 4 weeks of the drug (total of 16 weeks of therapy), and those who had received itraconazole (pulse) therapy were given an extra pulse (fourth pulse). Patients were evaluated at 1.5, 3, 6, 12, and 18 months from the start of therapy. The efficacy measures included mycologic cure rate and clinical efficacy (mycologic cure plus clinical cure or clinical improvement so that 10% or less of nail plate was clinically involved). RESULTS: There were 101 elderly patients enrolled in the study with 50 and 51 patients receiving terbinafine and itraconazole, respectively. The terbinafine group consisted of 28 men and 22 women, age (mean +/- standard error [SE]) 68.0 +/- 0.9 years, duration of onychomycosis (mean +/- SE) 18.2 +/- 1.4 years, number of nails involved (mean +/- SE) 5.5 +/- 0.5, and percent baseline nail plate area involved (mean +/- SE) 67.5% +/- 4.2%. The corresponding figures for the itraconazole (pulse) group were 24 men and 27 women, age (mean +/- SE) 68.8 +/- 0.8 years, duration of onychomycosis (mean +/- SE) 16.1 +/- 1.7 years, number of nails involved (mean +/- SE) 6.0 +/- 0.7, and percent baseline nail plate area involved (mean +/- SE) 74.9% +/- 3.8%, respectively, with no significant difference between the groups. At month 6, the number of patients that required an extra 4 weeks of terbinafine in the allylamine group or an extra itraconazole pulse in the triazole group was 13 of 50 and 23 of 51, respectively. The mycologic cure rate and clinical efficacy at 18 months from the start of therapy for the terbinafine group were 64.0% and 62.0%, respectively. The corresponding figures for the itraconazole (pulse) group were 62.7% and 60.8%, respectively, with no significant difference between the 2 groups. There were no dropouts during therapy. For both groups the drug appeared safe with no significant adverse events (AEs) or clinically significant laboratory abnormalities. All the AEs were mild and transient. There was high compliance with both regimens. CONCLUSIONS: In the elderly, for the treatment of dermatophyte toe onychomycosis, both terbinafine (continuous) and itraconazole (pulse) therapies are effective, safe, and associated with high compliance.

The treatment of moderate to severe psoriasis with a new anti-CD11a monoclonal antibody.

BACKGROUND: Anti-CD11a (hu1124) is a humanized monoclonal antibody directed against the CD11a subunit of LFA-1. This study investigated whether treatment with anti-CD11a antibody provides clinical benefit to patients with moderate to severe plaque psoriasis. METHODS: This was a double-blind, placebo-controlled, phase II, multicenter study. In total, 145 patients with minimum Psoriasis Area and Severity Index scores of 12 and affected body surface area of 10% or more were sequentially enrolled into low-dose (0.1 mg/kg, n = 22) or high-dose (0.3 mg/kg, n = 75) groups. Within groups, patients were randomized to treatment or placebo (n = 48) in a 2:1 ratio. Drug was administered intravenously at weekly intervals for 8 weeks. RESULTS: The percentage of subjects achieving more than 50% improvement in physician's global assessment at day 56 (1 week after final dose) was 15% and 48% for placebo and 0.3 mg/kg of drug, respectively (P =.002). A physician's global assessment of excellent (>75% improvement) was greater in the 0.3 mg/kg group versus placebo (25% vs 2%, P =.0003). Average Psoriasis Area and Severity Index scores at day 56 were 13.9 +/- 7.5 (placebo) and 10.9 +/- 8.4 (0.3 mg/kg) (P <.0001). Epidermal thickness was reduced in the 0.3 mg/kg group compared with the placebo group (37% vs 19%, P =.004). Treatment was well tolerated; mild to moderate flu-like complaints were the most common adverse events. White blood cell counts and lymphocyte counts transiently increased. Depletion of circulating lymphocytes did not occur. CONCLUSIONS: Anti-CD11a antibody administered intravenously in 8 weekly doses of 0.3 mg/kg was well tolerated and induced clinical and histologic improvements in psoriasis.

Moisturizers: what they are and how they work.

Moisturizers are widely used in various dermatologic and cosmetic skin therapies. Different classes of moisturizers are based on their mechanism of action, including occlusives, humectants, emollients and protein rejuvenators. Commercially available moisturizers often utilize components of each of these classes to provide their beneficial effect. Dry skin (xerosis) is the major indication of use. Others include atopic dermatitis, irritant contact dermatitis, ichthyosis, and dermatoheliosis. Although generally efficacious, moisturizers can cause a number of unwanted side-effects, including occlusive folliculitis, irritation, allergic contact dermatitis and contact urticaria.

Once weekly fluconazole is effective in children in the treatment of tinea capitis: a prospective, multicentre study.

In an open, multicentre evaluation carried out in Brazil, Canada and South Africa we have demonstrated that fluconazole 8 mg kg-1 once weekly is effective in tinea capitis caused by Trichophyton and Microsporum species. There were 61 children, aged (mean +/- SE) 5.0 +/- 0.3 years; weight (mean +/- 5.6) 20.0 +/- 0.9 kg; 41 males, 20 females; one Asian, 57 Black, one Caucasian and two Hispanic. The organisms were Trichophyton violaceum (33 patients), T. tonsurans (11) and Microsporum canis (17). The extent of tinea capitis at pretherapy was: mild (18 patients), moderate (30) and severe (13). Patients with tinea capitis due to Trichophyton species were initially treated for 8 weeks with an extra 4 weeks of fluconazole if clinically indicated. All 44 patients with tinea capitis due to Trichophyton species were completely cured (clinically and mycologically) when evaluated 8 weeks after completion of active treatment, following 8 weeks of once weekly dosing in 35 patients and 12 weeks of once weekly dosing in nine patients. In Microsporum canis tinea capitis, an extra 4 weeks was administered at week 12 in patients where it was clinically indicated at the time. Sixteen of 17 patients with M. canis tinea capitis were completely cured (clinically and mycologically) when evaluated 8 weeks following the end of treatment when given for 8, 12 and 16 weeks in 12, one and three patients, respectively. Overall, complete cure (clinical and mycological) occurred in 60 of 61 patients at follow-up 8 weeks from the end of therapy. The duration of once weekly fluconazole in the 60 patients was 8 weeks (47 patients), 12 weeks (10 patients) and 16 weeks (three patients), respectively. Clinical adverse effects consisted of a mild, reversible gastrointestinal complaint in three (4.9%) of 61 children. A laboratory abnormality with elevated liver function tests was observed in one (5.9%) of 17 patients; this was asymptomatic, and reversible. No patient discontinued therapy. The data suggest that once weekly fluconazole dosing is effective, safe and associated with high compliance when used to treat tinea capitis.

Prevalence and epidemiology of onychomycosis in patients visiting physicians' offices: a multicenter canadian survey of 15,000 patients.

A prospective, multicenter study to determine the epidemiology of onychomycosis was performed in the offices of 3 dermatologists and 1 family physician in Ontario, Canada. In the sample of 15,000 patients, abnormal-appearing nails were observed in 2505 persons (16. 7%). There were 1199 patients (8%) with toenail or fingernail onychomycosis confirmed on mycologic examination, with 1137 patients (7.6%) who had only pedal onychomycosis, 40 patients with toenail and fingernail onychomycosis (0.27%), and 22 patients (0.15%) with only fingernail onychomycosis. The condition was more common in male patients (P <.0001) and older persons (P <.0001). The ratio of onychomycosis in toenails/fingernails was 19:1. When onychomycosis was present in toenails, the ratio of distal/lateral subungual onychomycosis (DLSO) to white superficial onychomycosis to proximal subungual onychomycosis was 360:59:1. The extent of DLSO in toenails was mild (< or =25% nail involvement), moderate (26%-74% disease), and severe (> or =75% nail involvement) in 27.6%, 39.9%, and 32.5% of patients, respectively. After adjusting for the age and sex distribution of the general population, the projected rate of onychomycosis in Canada is 6.5% (95% confidence interval [CI], 6. 1%-6.9%). The organisms causing toenail onychomycosis were 90.5% dermatophyte, 7.8% nondermatophyte molds, and 1.7% Candida spp. The corresponding organisms causing fingernail onychomycosis were 70.8%, 0%, and 29.2%, respectively. In a large sample of 15,000 patients, abnormal-appearing nails were present in 17% of the sample with mycologic evidence of toenail or fingernail onychomycosis in 8%. The projected prevalence of onychomycosis in Canada is 6.5% (95% CI, 6. 1%-6.9%).

Intermittent short duration therapy with fluconazole is effective for tinea capitis.

We have demonstrated in an open multicentre investigation that oral fluconazole 6 mg/kg daily for 2 weeks, followed, if clinically indicated four weeks from the start of therapy, by an extra week of treatment at the same dosage, may be effective and safe in the treatment of tinea capitis. Of a total of 48 patients, there were 42 evaluable children < 18 years old (19 boys, 23 girls; mean age 6.2 years, range 1.5-16). The causative organisms were Trichophyton tonsurans (38 subjects) and T. violaceum (four). In the 42 evaluable patients, a 2-week course of fluconazole was administered in 21, with the remainder requiring 1 additional week of therapy. At follow-up 12 weeks from the start of therapy, mycological and clinical cure was recorded in 37 of the 42 evaluable patients (88.1%, 95% confidence interval 83.1-93.1%). The treatment was well tolerated, with no clinical adverse effects. This regimen appears to be effective and safe, and is associated with high compliance. The preliminary results of the investigation need to be evaluated in a larger sample of patients, and in tinea capitis caused by zoophilic species.

Onychomycosis: predisposed populations and some predictors of suboptimal response to oral antifungal agents.

The population groups predisposed to onychomycosis and factors associated with a poor response to antifungal therapy may be subdivided into (a) genetic, (b) environmental, (c) systemic conditions, (d) local nail characteristics, and (e) other miscellaneous items. By paying attention to the scenarios that may lead to a suboptimal response to the therapy and a higher probability of relapse of the onychomycosis, it may be possible to improve the overall cost-effectiveness of treatments for onychomycosis. Besides attempting to achieve a cure when treating onychomycosis it is important to take steps to prevent reinfection with fungal organisms.

Cutaneous adverse effects associated with terbinafine therapy: 10 case reports and a review of the literature.

Terbinafine is an allylamine antifungal agent widely used to treat dermatophyte onychomycosis and dermatomycoses. We report 10 severe cutaneous adverse reactions associated with terbinafine therapy which required discontinuation of the antifungal agent: erythema multiforme (five patients), erythroderma (one), severe urticaria (one), pityriasis rosea (one) and worsening of pre-existing psoriasis (two patients). The spectrum of cutaneous adverse effects associated with terbinafine therapy is reviewed. Patients should be counselled about discontinuing terbinafine at the onset of a cutaneous eruption and about seeking medical advice about further management.

Hepatitis associated with terbinafine therapy: three case reports and a review of the literature.

Terbinafine is an allylamine antifungal agent first launched in the USA in May 1996 with an estimated 7.5 million individuals worldwide having used the drug. Given orally it is effective for the treatment of dermatophyte infections and is prescribed predominantly for the superficial mycoses. Adverse effects have been reported in 46.7% of patients receiving the oral drug (compared with 29.2% receiving placebo, the attributable risk to terbinafine being 17.5%). Thus, oral terbinafine is associated with the rare development of symptomatic idiosyncratic hepatobiliary dysfunction (1:45,000-1:54,000) and we now describe three patients who developed this disorder whilst taking the medication. The hepatitis produced has the features of both hepatocellular necrosis (with elevations of hepatic enzyme concentrations) and cholestatic injury (with elevations of alkaline phosphatase and cholesterol levels), the latency period between the start of medication and the development of liver injury being approximately 4-6 weeks. The US terbinafine product monograph recommends that serum hepatic enzymes should be assessed in individuals receiving terbinafine for more than 6 weeks, as a result of which some physicians monitor these values at baseline and at 4-6 weeks.

Carbon dioxide laser-treatment of resistant verrucae vulgaris: retrospective analysis.

BACKGROUND: Verrucae are a very common dermatological problem that can be both painful and bothersome to the individual as well as costly to the health care system. In some cases verrucae can be notoriously resistant to therapy. OBJECTIVE: To determine the cure rate, side effect profile, and overall satisfaction with CO2 laser treatment of recalcitrant verrucae vulgaris. METHODS: A retrospective survey was sent to over 200 patients who had resistant verrucae vulgaris treated with the carbon dioxide laser at The Toronto Hospital (Western Division) from 1989 to 1994. RESULTS: Ninety-two complete responses were received. The overall cure rate was 64.1% at 12 months. There was no significant difference in cure rates between single compared to multiple warts (p = .824 Fisher's exact test). The duration of the wart being present showed no difference in cure rate (p = .801 Fisher's exact test). The location of the wart also had no influence on the cure rate (p = .433 Fisher's exact test). Overall, 71.7% of the patients were happy with the laser treatment and 85.7% would have it done again. CONCLUSION: The carbon dioxide laser is an effective treatment of resistant verrucae vulgaris.

Terbinafine therapy may be associated with the development of psoriasis de novo or its exacerbation: four case reports and a review of drug-induced psoriasis.

Adverse effects may occur in 10.4% of patients receiving terbinafine therapy, with cutaneous reactions in 2.7%. We describe the development of psoriasis in four patients who took oral terbinafine. Two patients had plaque-type psoriasis that flared 12 and 17 days, respectively, after starting terbinafine. Another patient developed pustular-type psoriasis de novo after 27 days of terbinafine therapy. The fourth patient was a psoriatic with stable plaque disease who experienced a pustular flare after taking terbinafine for 21 days. We are aware of only one report in the literature in which a patient developed pustular psoriasis de novo after 5 days of terbinafine therapy. In all patients the psoriasis cleared or lessened after discontinuation of terbinafine and institution of antipsoriatic therapy.

Onychomycosis in children: prevalence and treatment strategies.

BACKGROUND: Onychomycosis is observed less frequently in children than adults. Until recently management of onychomycosis in children included topical formulations, oral griseofulvin, and in some cases deferral of treatment. OBJECTIVE: We attempted to determine the prevalence of onychomycosis in North American children 18 years old or younger attending our dermatology offices (three Canadian, two U.S.) and to report the group's experience using fluconazole, itraconazole, and terbinafine for onychomycosis. METHODS: We undertook a prospective, multicenter survey in which all children, regardless of presenting complaint, were examined for onychomycosis by a dermatologist. In instances of clinical suspicion appropriate nail samples were obtained for light microscopy and culture. RESULTS: A total of 2500 children under age 18 were examined in the five-center survey (1117 males and 1383 females, mean +/- S.E. age: 11.2 +/- 0.1 years). There was one child with fingernail and ten with mycologically confirmed toenail dermatophyte onychomycosis. The overall prevalence of onychomycosis was 0.44%. Considering those children whose primary or referring diagnosis was not onychomycosis or tinea pedis, the prevalence of onychomycosis was 0.16%. Outside the survey we have seen six other children with dermatophyte onychomycosis; these 17 cases form the basis for the remainder of the report. Of the 17 children, eight (47%) had concomitant tinea pedis infection, and in 11 (65%) a sibling, parent, or grandparent had onychomycosis or tinea pedis. Management included topical terbinafine (two patients: one cured, one failed therapy), topical ketoconazole (one patient: clinical improvement), oral fluconazole (two patients: one cured, one had Down's syndrome and was noncompliant), oral itraconazole (four patients: three cured with subsequent recurrence at follow-up in one patient, one lost to follow-up), oral terbinafine (five patients: four cured with subsequent recurrence at follow-up in one patient, one failed therapy). One child received no therapy following discussion with the parents, one was lost to follow-up and one was found to have asymptomatic hepatic dysfunction with hepatitis C at pretherapy bloodwork. CONCLUSION: The prevalence of onychomycosis in our sample of North American children 18 years old or younger was 0.44% (n = 2500). In the subset of children whose primary or referring diagnosis was not onychomycosis, the prevalence of onychomycosis was 0.16%. Children with onychomycosis should be carefully examined for concomitant tinea pedis, and their parents and siblings checked for onychomycosis and tinea pedis. The newer oral antifungal agents fluconazole, itraconazole, and terbinafine may be effective and well-tolerated in the treatment of onychomycosis in this age group. These drugs should be carefully evaluated in a larger cohort of children with onychomycosis.

Itraconazole pulse therapy is effective in the treatment of tinea capitis in children: an open multicentre study.

In an open multicentre study we have demonstrated that itraconazole pulse therapy, 5 mg/kg per day, is effective and safe in the management of tinea capitis in 10 children (seven boys, three girls, mean age: 6.6 years, age range 4-11 years). The causative organisms were Trichophyton tonsurans (six cases), T. violaceum (two cases), T. soudanense (one case) and Microsporum gypseum (one case). Each pulse of drug therapy lasted 1 week with 2 weeks off between consecutive pulses. One, two and three pulses produced complete, clinical and mycological, cure in one, six and three patients, respectively. The children tolerated the treatment well and there were no clinical or laboratory adverse effects. This 1-week pulse therapy regimen resulted in a high degree of compliance. The preliminary results of this study are promising and need to be evaluated in a larger sample of patients.
