Methodological and reporting quality of non-inferiority randomized controlled trials comparing antifungal therapies: a systematic review. Clin Microbiol Infect 2021; 28:640-648. [PMID: 34763055 DOI: 10.1016/j.cmi.2021.11.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 10/30/2021] [Accepted: 11/01/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Detailed reporting is essential in non-inferiority randomized controlled trials (NI-RCTs) to assess evidence quality, as these trials inform standards of care. OBJECTIVES The primary objective was to evaluate the methodological and reporting quality of antifungal NI-RCTs. DATA SOURCES Medline, EMBASE, the Cochrane CENTRAL and the United States Federal Drug Administration (FDA) drugs database were searched to 9 September 2020. STUDY ELIGIBILITY CRITERIA NI-RCTs differing by antifungal formulation, type, dose, administration and/or duration were included. Articles were independently assessed in duplicate using quality indicators developed by the Consolidated Standards of Reporting Trials (CONSORT) group. PARTICIPANTS Patients enrolled in antifungal trials for prophylactic and therapeutic use. METHODS The Cochrane RoB 2.0 tool was used to assess risk of bias. Descriptive statistics were used; all statistical tests were two sided. RESULTS Of 32 included studies, 22 (68.7%) did not justify the NIM. Handling of missing data was not described in 20 (62.5%). Intention-to-treat (ITT) and per-protocol (PP) analyses were both reported in 12/32 (37.5%) studies. Eleven of 32 studies (34.3%) reported potentially misleading conclusions. Industry-financed studies were more likely to report only the ITT analysis (n = 14/27, 51.9%). Methodological and reporting quality was unaffected by publication year; risk of bias from missing data changed over time. Overall risk of bias across included studies was moderate to high, with high risk in randomization process (n = 8/32, 25%), missing outcome data (n = 5/32, 15.6%), and selection of reported result (n = 9/32, 28.1%). CONCLUSIONS Justification of the non-inferiority margin, reporting of ITT and PP analyses, missing data handling description, and ensuring conclusions are consistent with reported data is necessary to improve CONSORT adherence. Small sample size and overall risk of bias are study limitations. (Systematic Review Registration Number PROSPERO CRD42020219497).

Abstract
Non-inferiority randomized controlled trial (RCT) effectiveness may erode when results favour the active control over time, and when a decreasingly effective control arm is used in serial trials. We analyzed 32 antifungal noninferiority RCTs (NI-RCTs) for these scenarios in this secondary analysis of a systematic review. Our exploratory analysis suggests that the erosion risk in the effectiveness of antifungal non-inferiority trials is uncommon. Findings are limited by small sample size, and overall risk of bias.

Tacrolimus 0.1% versus ciclopiroxolamine 1% for maintenance therapy in patients with severe facial seborrheic dermatitis: A multicenter, double-blind, randomized controlled study. J Am Acad Dermatol 2020; 84:1278-1284. [PMID: 33010323 DOI: 10.1016/j.jaad.2020.09.055] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 09/01/2020] [Accepted: 09/03/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND No long-term maintenance therapy has been tested in patients with seborrheic dermatitis (SD). OBJECTIVE We sought to compare the efficacy and tolerance of tacrolimus 0.1% ointment versus ciclopiroxolamine 1% cream as maintenance therapy for severe SD. METHODS This double-blind randomized controlled study was conducted from 2014 to 2017 in 5 Dermatology Departments and 15 dermatology practices in France. Consecutive patients with severe and chronic facial SD were included. Patients were initially treated with desonide 0.05% cream twice daily for 7 days. Patients cleared after this open phase were randomized to receive tacrolimus 0.1% or ciclopiroxolamine 1% cream 2 times a week 24 weeks. The primary endpoint was disease-free-duration, defined as the time from randomization to first relapse. RESULTS One hundred fourteen patients were randomized (tacrolimus, n = 57; ciclopiroxolamine, n = 57). Twelve patients relapsed in the tacrolimus group after a median delay of 91.5 days (range 15-195 days) versus 23 patients in the ciclopiroxolamine group (median delay, 27 days [range 13-201 days]). Comparison of disease-free duration curves showed that patients in the tacrolimus group had a longer duration of complete remission than those in the ciclopiroxolamine group (P = .018), corresponding to a hazard ratio of relapse of 0.44 (95% confidence interval 0.22-0.89; P = .022). LIMITATIONS The theoretical sample size was not reached. CONCLUSION Tacrolimus 0.1% is more effective than ciclopiroxolamine 1% as maintenance therapy for patients with facial SD.

Abstract
The injudicious use of antifungals, indiscriminate use of corticosteroids for instant relief, persistence of predisposing factors like sweat retention and uncontrolled diabetes, and emerging resistance to antifungals across the globe have rendered the management of an erstwhile simple infection, the superficial cutaneous mycoses highly complicated and tricky. Ciclopirox is an old yet efficacious, versatile, and safe topical antifungal of the hydroxypyridone family. Despite its numerous beneficial properties over the majority of other topical antifungals, it remains underutilized.

Abstract
BACKGROUND Facial seborrheic dermatitis (SD), a chronic inflammatory skin condition, can impact quality of life, and relapses can be frequent. Three broad categories of agents are used to treat SD: antifungal agents, keratolytics, and corticosteroids. Topical therapies are the first line of defense in treating this condition. OBJECTIVE Our objective was to critically review the published literature on topical treatments for facial SD. METHODS We searched PubMed, Scopus, Clinicaltrials.gov, MEDLINE, Embase, and Cochrane library databases for original clinical studies evaluating topical treatments for SD. We then conducted both a critical analysis of the selected studies by grading the evidence and a qualitative comparison of results among and within studies. RESULTS A total of 32 studies were eligible for inclusion, encompassing 18 topical treatments for facial SD. Pimecrolimus, the focus of seven of the 32 eligible studies, was the most commonly studied topical treatment. CONCLUSION Promiseb®, desonide, mometasone furoate, and pimecrolimus were found to be effective topical treatments for facial SD, as they had the lowest recurrence rate, highest clearance rate, and the lowest severity scores (e.g., erythema, scaling, and pruritus), respectively. Ciclopirox olamine, ketoconazole, lithium (gluconate and succinate), and tacrolimus are also strongly recommended (level A recommendations) topical treatments for facial SD, as they are consistently effective across high-quality trials (randomized controlled trials).

Abstract
BACKGROUND Lithium succinate and gluconate are effective alternative options licensed for the topical treatment of seborrhoeic dermatitis (SD). OBJECTIVE Their mode of action is not fully elucidated. Minimal inhibitory concentrations against Malassezia (M.) yeasts, which play an important role in SD, are very high. METHODS An assay based on the hydrolysis of ethyl octanoate enables us to test the hydrolytic activity of reference strains of the species M. globosa, M. sympodialis and M. furfur solely without interference by fungal growth as the free octanoic acid generated has antifungal activity. RESULTS In this assay the presence of alkali salts (lithium, sodium and potassium succinate resp.) in concentrations of 2%, 4% and 8% does not influence hydrolytic activity but the availability of the generated free fatty acid in a dose-dependent manner which was analysed by means of high-performance thin layer chromatography and densitometry. This was best effected with the lithium, followed by the sodium and only to a low degree by the potassium salt. As shown by attenuated total reflection Fourier transform infrared spectroscopy the free fatty acid reacted to the respective alkali soap and precipitate from solution. The alkali soaps could not be utilized by the M. spp. as shown in a modified Tween auxanogram and in lack of fungal growth by ethyl oleate in the presence of 8% lithium succinate. CONCLUSION The effect of lithium succinate on growth of M. yeasts and presumably in SD can be explained by a precipitation of free fatty acids as alkali soaps limiting their availability for the growth of these lipid-dependent yeasts.

Abstract
BACKGROUND Seborrhoeic dermatitis is a chronic inflammatory skin condition that is distributed worldwide. It commonly affects the scalp, face and flexures of the body. Treatment options include antifungal drugs, steroids, calcineurin inhibitors, keratolytic agents and phototherapy. OBJECTIVES To assess the effects of antifungal agents for seborrhoeic dermatitis of the face and scalp in adolescents and adults.A secondary objective is to assess whether the same interventions are effective in the management of seborrhoeic dermatitis in patients with HIV/AIDS. SEARCH METHODS We searched the following databases up to December 2014: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 11), MEDLINE (from 1946), EMBASE (from 1974) and Latin American Caribbean Health Sciences Literature (LILACS) (from 1982). We also searched trials registries and checked the bibliographies of published studies for further trials. SELECTION CRITERIA Randomised controlled trials of topical antifungals used for treatment of seborrhoeic dermatitis in adolescents and adults, with primary outcome measures of complete clearance of symptoms and improved quality of life. DATA COLLECTION AND ANALYSIS Review author pairs independently assessed eligibility for inclusion, extracted study data and assessed risk of bias of included studies. We performed fixed-effect meta-analysis for studies with low statistical heterogeneity and used a random-effects model when heterogeneity was high. MAIN RESULTS We included 51 studies with 9052 participants. Of these, 45 trials assessed treatment outcomes at five weeks or less after commencement of treatment, and six trials assessed outcomes over a longer time frame. We believe that 24 trials had some form of conflict of interest, such as funding by pharmaceutical companies.Among the included studies were 12 ketoconazole trials (N = 3253), 11 ciclopirox trials (N = 3029), two lithium trials (N = 141), two bifonazole trials (N = 136) and one clotrimazole trial (N = 126) that compared the effectiveness of these treatments versus placebo or vehicle. Nine ketoconazole trials (N = 632) and one miconazole trial (N = 47) compared these treatments versus steroids. Fourteen studies (N = 1541) compared one antifungal versus another or compared different doses or schedules of administration of the same agent versus one another. KetoconazoleTopical ketoconazole 2% treatment showed a 31% lower risk of failed clearance of rashes compared with placebo (risk ratio (RR) 0.69, 95% confidence interval (CI) 0.59 to 0.81, eight studies, low-quality evidence) at four weeks of follow-up, but the effect on side effects was uncertain because evidence was of very low quality (RR 0.97, 95% CI 0.58 to 1.64, six studies); heterogeneity between studies was substantial (I² = 74%). The median proportion of those who did not have clearance in the placebo groups was 69%.Ketoconazole treatment resulted in a remission rate similar to that of steroids (RR 1.17, 95% CI 0.95 to 1.44, six studies, low-quality evidence), but occurrence of side effects was 44% lower in the ketoconazole group than in the steroid group (RR 0.56, 95% CI 0.32 to 0.96, eight studies, moderate-quality evidence).Ketoconozale yielded a similar remission failure rate as ciclopirox (RR 1.09, 95% CI 0.95 to 1.26, three studies, low-quality evidence). Most comparisons between ketoconazole and other antifungals were based on single studies that showed comparability of treatment effects. CiclopiroxCiclopirox 1% led to a lower failed remission rate than placebo at four weeks of follow-up (RR 0.79, 95% CI 0.67 to 0.94, eight studies, moderate-quality evidence) with similar rates of side effects (RR 0.9, 95% CI 0.72 to 1.11, four studies, moderate-quality evidence). Other antifungalsClotrimazole and miconazole efficacies were comparable with those of steroids on short-term assessment in single studies.Treatment effects on individual symptoms were less clear and were inconsistent, possibly because of difficulties encountered in measuring these symptoms.Evidence was insufficient to conclude that dose or mode of delivery influenced treatment outcome. Only one study reported on treatment compliance. No study assessed quality of life. One study assessed the maximum rash-free period but provided insufficient data for analysis. One small study in patients with HIV compared the effect of lithium versus placebo on seborrhoeic dermatitis of the face, but treatment outcomes were similar. AUTHORS' CONCLUSIONS Ketoconazole and ciclopirox are more effective than placebo, but limited evidence suggests that either of these agents is more effective than any other agent within the same class. Very few studies have assessed symptom clearance for longer periods than four weeks. Ketoconazole produced findings similar to those of steroids, but side effects were fewer. Treatment effect on overall quality of life remains unknown. Better outcome measures, studies of better quality and better reporting are all needed to improve the evidence base for antifungals for seborrhoeic dermatitis.

Abstract
Seborrhoeic dermatitis (SD) is a common chronic inflammatory skin disease. Although the exact pathogenesis of SD is unknown, Malassezia yeasts as well as genetic and environmental factors have been implicated. The aim of this study was to evaluate the efficacy of terbinafine 1% cream on SD lesions with face localisation. Thirty-five patients with SD were included in the study. Patients applied terbinafine 1% cream twice daily for four weeks. The severity of the signs (erythema, scaling, infiltration) was assessed using a 4-point score (0=absent, 1=mild, 2=moderate, and 3=intense) at baseline and at the 2nd and 4th weeks of the therapy. Also, self-assessment was done by the patients on a 100 mm visual analogue score (VAS) at each visit. Complete remission was observed in 10 (32.3%) patients at the end of the therapy. Statistically significant reductions in the scores of all parameters were observed at both the 2nd and 4th weeks of the therapy. Patients' self assessments in the 2nd and 4th weeks were similarly better than at the baseline.

Abstract
WHAT IS KNOWN AND OBJECTIVE 6-Cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridone (ciclopirox) and specifically its olamine salt 6-cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridone 2-aminoethanol salt (ciclopirox olamine) are anti-fungal agents currently used for the treatment of mild to moderate cutaneous fungal infection. Our objective is to comment on the opportunity to rapidly reposition ciclopirox and its olamine for the treatment of haematologic malignancy by leveraging its prior published toxicology and pharmacology data. COMMENT Ciclopirox olamine chelates intracellular iron and displays preclinical efficacy in the treatment of haematologic malignancy. Currently, an ongoing study is evaluating topical ciclopirox olamine for the treatment of cervical cancer. Doses of ciclopirox olaine required for a systemic anti-cancer effect appear pharmacologically achievable. However, caution is required as at the highest doses tested in animal toxicology studies, irreversible cardiac degeneration was observed. WHAT IS NEW AND CONCLUSION The existing pharmacology and toxicology data suggest that systemic ciclopirox olamine could be repositioned as a new investigational anti-cancer agent. The available pharmacology and toxicology data should aid in the design of phase I clinical trials of this agent in patients with refractory haematologic malignancies.

Abstract
Invasive fungal infections with primary and opportunistic mycoses have become increasingly common in recent years and pose a major diagnostic and therapeutic challenge. They represent a major area of concern in today's medical fraternity. The occurrence of invasive fungal diseases, particularly in AIDS and other immunocompromised patients, is life-threatening and increases the economic burden. Apart from the previously known polyenes and imidazole-based azoles, newly discovered triazoles and echinocandins are more effective in terms of specificity, yet some immunosuppressed hosts are difficult to treat. The main reasons for this include antifungal resistance, toxicity, lack of rapid and microbe-specific diagnoses, poor penetration of drugs into sanctuary sites, and lack of oral or intravenous preparations. In addition to combination antifungal therapy, other novel antimycotic treatments such as calcineurin signaling pathway blockers and vaccines have recently emerged. This review briefly summarizes recent developments in the pharmacotherapeutic treatment of invasive fungal infections.

Abstract
BACKGROUND Retapamulin is a novel pleuromutilin antibacterial developed for topical use. OBJECTIVE To compare the efficacy and safety of retapamulin ointment, 1% (twice daily for 5 days), with sodium fusidate ointment, 2% (3 times daily for 7 days), in impetigo. METHODS A randomized (2:1 retapamulin to sodium fusidate), observer-blinded, noninferiority, phase III study in 519 adult and pediatric (aged > or = 9 months) subjects. RESULTS Retapamulin and sodium fusidate had comparable clinical efficacies (per-protocol population: 99.1 and 94.0%, respectively; difference: 5.1%, 95% confidence interval: 1.1-9.0%, p = 0.003; intent-to-treat population: 94.8 and 90.1%, respectively; difference: 4.7%, 95% confidence interval: -0.4 to 9.7%, p = 0.062). Bacteriological efficacies were similar. Success rates in the small numbers of sodium-fusidate-, methicillin- and mupirocin-resistant Staphylococcus aureus were good for retapamulin (9/9, 8/8 and 6/6, respectively). Both drugs were well tolerated. CONCLUSION Retapamulin is a highly effective and convenient new treatment option for impetigo, with efficacy against isolates resistant to existing therapies.

Abstract
Ciclopirox olamine is a synthetic hydroxypiridone derived, broad spectrum, antifungal agent which has been used effectively to treat seborrheic dermatitis. Seborrheic dermatitis is a chronic dermatosis, more common in men than women, which usually occurs in sites dense with sebaceous glands in the form of mild inflammatory desquamate erythema. Treatment modalities for seborrheic dermatitis include keratolytic agents, corticosteroids and antifungal agents. Due to its antimycotic and anti-inflammatory activities, ciclopirox olamine is established as an effective treatment for this condition.

Abstract
Seborrhoeic dermatitis (SD) is a recurrent, chronic inflammation of the skin that occurs on sebum rich areas such as the face, scalp and chest, characterised by red scaly lesions. The are many studies indicating that Malassezia yeasts play an important role in the aetiology of this condition, most of the evidence for which comes from demonstrated responsiveness to treatment with antifungal agents. Its aetiology, however, is far from being resolved. Some believe that it is the immune response of the skin to the Malassezia that is the cause of the disease. Traditional treatments of SD have been the use of keratolytic agents or corticosteroids. Since the discovery of ketoconazole, a considerable amount of research has been focused on determining the efficacy of various antifungal agents. This article reviews clinical trial data on treatment options available for SD.

Abstract
Seborrheic dermatitis (SD) is a common dermatological disorder that varies greatly in severity between individuals and with time. The etiology of this disease is poorly understood. Early investigators focused on the role of Malassezia (previously Pityrosporum) yeasts in the development of SD. Some researchers have hypothesized that there is an immunological component to SD and that this disease is caused by an altered immune response to Malassezia yeasts. However, other researchers view this condition as the result of hyperproliferation. Both antifungal and anti-inflammatory preparations have been used to treat SD effectively and safely. The wide range of antifungal formulations available (creams, shampoos, oral drugs) provides safe, effective and flexible treatment options for SD.

Abstract
Seborrheic dermatitis is a superficial fungal disease of the skin, occurring in areas rich in sebaceous glands. It is thought that an association exists between Malassezia yeasts and seborrheic dermatitis. This may, in part, be due to an abnormal or inflammatory immune response to these yeasts. The azoles represent the largest class of antifungals used in the treatment of this disease to date. In addition to their antifungal properties, some azoles, including bifonazole, itraconazole, and ketoconazole, have demonstrated anti-inflammatory activity, which may be beneficial in alleviating symptoms. Other topical antifungal agents, such as the allylamines (terbinafine), benzylamines (butenafine), hydroxypyridones (ciclopirox), and immunomodulators (pimecrolimus and tacrolimus), have also been effective. In addition, recent studies have revealed that tea tree oil (Melaleuca oil), honey, and cinnamic acid have antifungal activity against Malassezia species, which may be of benefit in the treatment of seborrheic dermatitis. In cases where seborrheic dermatitis is widespread, the use of an oral therapy, such as ketoconazole, itraconazole, and terbinafine, may be preferred. Essentially, antifungal therapy reduces the number of yeasts on the skin, leading to an improvement in seborrheic dermatitis. With a wide availability of preparations, including creams, shampoos, and oral formulations, antifungal agents are safe and effective in the treatment of seborrheic dermatitis.
