Prevalence of prescribing topical corticosteroids to patients with lichen sclerosus following surgery for vulvar cancer: a survey among gynaecologic oncologists in The Netherlands

BACKGROUND

Vulvar lichen sclerosus (LS) is a chronic inflammatory dermatosis which can progress to precursor lesion differentiated vulvar intraepithelial neoplasia (dVIN) and vulvar squamous cell carcinoma (VSCC). The risk of developing recurrent vulvar cancer following LS-associated VSCC is high. Evidence suggests that treatment of LS with topical corticosteroids (TCS) can prevent progression to dVIN, VSCC and recurrences. However, current guidelines do not give any recommendation on the management of LS following surgery for VSCC. The aim of this study was to conduct a survey among all registered gynaecologic oncologists (GOs) in the Netherlands to evaluate the current management of LS patients without a history of VSCC (LSnoVSCC) and patients with LS following surgery for VSCC (LSVSCC).

METHODS

An online survey was distributed to all registered GOs in the Netherlands. Primary outcome measures were the frequency, type and duration of TCS treatment prescribed for LSnoVSCC and LSVSCC patients, separately. As a secondary outcome measure, reasons for treating or not treating patients with LSnoVSCC and LSVSCC with TCS were analysed.

RESULTS

Forty-four GOs completed the survey, resulting in a response rate of 75%. TCS were prescribed more often to patients with LSnoVSCC as compared to patients with LSVSCC (86% versus 52%, respectively, p < 0.001). If treatment was initiated, ultra-potent (class IV) TCS were most commonly prescribed for an indefinite period of time for both patient groups. The most reported reason for treating patients in both groups with TCS was symptoms, followed by clinical aspects of the lesion and prevention of progression to dVIN and VSCC.

CONCLUSION

The majority of GOs who participated in our study endorse the utilisation of long-term ultra-potent TCS therapy in both patients with LSnoVSCC and LSVSCC. Nevertheless, Dutch GOs are currently prescribing TCS more frequently to patients with LSnoVSCC than to patients with LSVSCC.

Drug-induced Steatohepatitis Caused by Long-term Use of Topical Steroids for Atopic Dermatitis: A Case Report

Atopic dermatitis is common in children and often treated with topical corticosteroids (TCs). A boy in his late teens who had been using TCs for atopic dermatitis was diagnosed with liver damage during a health checkup. A medical examination revealed severe steatotic liver disease and elevated liver enzyme levels despite the absence of typical symptoms such as central obesity. After discontinuation of TCs, an improvement in liver enzyme levels was observed, leading to the diagnosis of drug-induced steatohepatitis. This case underscores the potential liver risks associated with prolonged TC use in children, highlighting the need for parental education.

Clinical pharmacokinetics and pharmacodynamics of topical non-biological therapies for psoriasis patients

INTRODUCTION

Psoriasis is a chronic inflammatory cutaneous disease that causes patients psychosocial distress. Topical therapies are utilized for mild-to-moderate disease and for more severe disease in conjunction with systemic therapies. Topical corticosteroids are a cornerstone of treatment for psoriasis, but long-term use can cause stria and cutaneous atrophy and as well as systemic side effects such as topical steroid withdrawal. Non-steroidal topical therapies tend to be safer than topical corticosteroids for long-term use.

AREAS COVERED

We conducted a literature review on the pharmacokinetic (PK) and pharmacodynamic (PD) properties of topical therapies for psoriasis. We discuss how the PK and PD characteristics of these therapies inform clinicians on efficacy and toxicity when prescribing for patients.

EXPERT OPINION

Topical corticosteroids, used intermittently, are very safe and effective. Long-term, continuous use of topical corticosteroids can cause systemic side effects. Several generic and newly approved non-steroidal options are available, but no head-to-head studies compare the effectiveness of the generics (vitamin D analogs, tacrolimus, pimecrolimus) against the newer therapies (roflumilast, tapinarof). Patients often do not respond to topical therapies due to poor adherence to treatment regimens. For patients resistant to topical treatment, phototherapy or systemic therapy may be an option.

Integrative Approaches for the Diagnosis and Management of Erosive Oral Lichen Planus

Erosive oral lichen planus (EOLP) represents a significant challenge in dental and medical management due to its chronic inflammatory nature, painful symptoms, and impact on quality of life. This study aims to evaluate the current diagnostic approach with novel non-invasive techniques, such as dermoscopy, and also the landscape of treatment options for EOLP, focusing on its efficacy, safety, and the challenges that it present in clinical practice. Through a comprehensive literature review, we explored the use of topical corticosteroids, systemic immunosuppressants, biologics, and Janus kinase (JAK) inhibitors in treating EOLP, alongside examining patient compliance, psychological impacts, and the risk of adverse effects and recurrence. Our findings reveal that while topical corticosteroids are the cornerstone of EOLP treatment, offering symptomatic relief, their long-term use is limited by side effects and tolerance development. Systemic therapies and biologics provide alternatives for refractory cases but necessitate careful adverse effect monitoring. JAK inhibitors show promise as an innovative treatment avenue but require more evidence on long-term safety and efficacy. This study highlights the necessity of personalized treatment approaches due to the variable disease course and response to treatment, underscoring the importance of a multidisciplinary strategy in managing EOLP. The complexity of EOLP treatment, compounded by its psychological and quality of life impacts, demands ongoing research into targeted therapies, the establishment of standardized treatment protocols, and the development of effective outcome measures to improve patient care and treatment outcomes.

Adverse events from topical corticosteroid use in chronic hand eczema - Findings from the Danish Skin Cohort

Background

Topical corticosteroids (TCS) are used to treat most patients with chronic hand eczema (CHE), but knowledge about TCS-related adverse events in CHE is limited.

Objectives

To investigate patient-reported adverse events to TCS in CHE patients.

Methods

Data on adverse events related to TCS use in patients with CHE were analyzed from the Danish Skin Cohort; a prospective survey of a hospital cohort. We assessed patients' knowledge about TCS use and adverse event risks, and preference of TCS versus a nonsteroidal topical alternative.

Results

Of 724 adults with CHE (64.0% women; mean age 57.5 [standard deviation 12.8] years), 64.1% reported skin atrophy, 41.4% cracks/fissures, 23.9% bleeding, 45.9% pain/stinging sensation, 40.0% reduced hand dexterity, and 40.2% worsening of CHE signs or symptoms from using TCS. We observed CHE-severity-dependent associations (all groups; P < .0001). Most patients (76.4%) would prefer a nonsteroidal option, 10.9% were neutral/indifferent, and 12.7% would prefer TCS for CHE. The median numerical rating scale-score (ranging from 0 to 10) was 10 (interquartile range 6-10) for preferring a nonsteroidal topical treatment.

Limitations

Differences across TCS formulations were unexplored.

Conclusion

TCS-related cutaneous adverse events were common. There is a desire from patients for novel steroid-free topical alternatives for CHE treatment.

Advancing Treatment in Atopic Dermatitis: A Comprehensive Review of Clinical Efficacy, Safety, and Comparative Insights Into Corticosteroids, Calcineurin Inhibitors, and Phosphodiesterase-4 Inhibitors as Topical Therapies

Atopic dermatitis (AD) is a pervasive and multifaceted dermatological disorder causing daily distress to afflicted individuals worldwide. This comprehensive review synthesizes the historical and contemporary advancements in therapeutic strategies, offering a critical analysis of their efficacy, safety profiles, and adaptability. The enduring role of topical corticosteroids in managing AD is examined, acknowledging their potent anti-inflammatory properties alongside their potential adverse side effects, particularly in extended usage. The article explores the utilization of topical calcineurin inhibitors like tacrolimus and pimecrolimus, highlighting their novel anti-inflammatory pathways while also scrutinizing concerns over potential malignancies that relegate them to second-line therapy. The present investigation features the emergence of crisaborole, a phosphodiesterase four inhibitor. Its innovative mode of action, benign safety profile, and applicability to mild and moderate AD are thoroughly evaluated. The review also includes challenges, particularly cost considerations, which constrain accessibility and necessitate nuanced implementation in therapeutic regimens. This study underscores the need for persistent investigation, teamwork, and innovations in managing AD. In this regard, AD requires a united approach between clinicians, researchers, affected individuals, and policymakers to refine patient-focused treatment and develop precise, economical strategies to address this chronic and frequently life-altering health condition.

Comparative efficacy of systemic treatments for atopic dermatitis in adults

INTRODUCTION

Atopic dermatitis is a prevalent skin condition causing dry, pruritic, inflammatory skin lesions that can result in patient distress. Various emerging classes of therapy, including biologics and Janus kinase inhibitors, have been developed in recent years.

AREAS COVERED

A literature search of PubMed was conducted to explore existing literature and clinical trials. Treatment options and adverse effects were summarized by class and severity. JAK inhibitors and biologics are efficacious options for adults with severe atopic dermatitis. Using the Eczema Area and Severity Index (EASI) from 11 randomized control trials, the highest efficacy was seen with upadacitinib 30 mg with 70% of patients achieving EASI-75. Older, immune-inhibiting treatment options are still appropriate options to improve patient conditions. A meta-analysis of 39 randomized control trials concluded high dose cyclosporine is more effective at improving quality of life and itch when compared to azathioprine and methotrexate. Newly developed topical and systemic medications improve disease and itch severity and can be considered in patients without adequate control with their initial treatment regimen. Adverse effects must be considered when using the newer options, although major adverse events were not seen.

EXPERT OPINION

Current management options are efficacious, but adherence is required for any effect.

Pretibial myxedema in Grave's disease: A case report and treatment review of the literature

Key Clinical Message

Pretibial myxedema is a rare skin lesion in Grave's disease, which required topical glucocorticoid administration in long-term treatment. The patient's lesion has shrunk and become flatter than before treatment.

Abstract

We present a case of biopsy-verified pretibial myxedema in a 70-year-old male patient with diagnosed hyperthyroidism and no prior history of Graves' disease. Topical corticosteroid and antithyroid drug administration led to successful resolution of the skin lesions. This case emphasizes the importance of considering pretibial myxedema even in atypical presentations of Graves' disease and underscores the value of prompt treatment.

The efficacy of a transdermal hydrogel patch containing betamethasone dipropionate for treatment of chronic hand eczema: A single-blind, randomized and controlled trial

BACKGROUND

Topical corticosteroids under occlusion have been used to enhance the treatment of eczema. However, no study has investigated the efficacy of a steroid-containing transdermal patch for the treatment of chronic hand eczema.

METHODS

We conducted a randomized, controlled, assessor-blinded trial to determine the efficacy of a transdermal patch containing betamethasone dipropionate compared to topical betamethasone dipropionate ointment in the treatment of mild to moderate chronic hand eczema. The patients were included and assigned to receive either the transdermal patch once daily at night or the ointment twice daily for a period of 8 weeks. The outcomes were assessed using the Hand Eczema Severity Index (HECSI), Physical Global Assessment (PGA) score, self-reported compliance, level of patient satisfaction, quality of life, and side effects.

RESULTS

Fifty-six patients completed this study. At 8 weeks, there was a significant reduction in the HECSI scores in both the transdermal patch and topical ointment groups compared to those measured at baseline (14.61 to 1.86, p < 0.001; 18.46 to 3.43, p < 0.001, respectively) without a statistically significant difference between the two groups. Similarly, the two groups did not show any significant difference in the PGA scores, quality of life and side effects. However, the transdermal patch group reported better compliance and a higher level of patient satisfaction than the topical ointment group.

CONCLUSION

The transdermal corticosteroid patch has proven to be a safe and effective treatment, comparable to topical corticosteroids, after 8 weeks of use. Its sustained-release properties, along with once-daily use, can improve patient satisfaction and promote greater adherence to the treatment.

Trends in price for topical corticosteroids from 2017 to 2021 and the opportunity for cost savings identifiable at the point of care: A retrospective cross-sectional study

BACKGROUND

Topical corticosteroids possess numerous generics and similar-strength substitutes. Affordability can impact obtaining the medication prescribed.

OBJECTIVE

To determine recent trends in topical corticosteroid pricing and potential for cost saving.

METHODS

A retrospective cross-sectional study analyzing all prescriptions dispensed for topical corticosteroids from January 1, 2017 through December 31, 2021, using a US all-payer pharmacy-claims database and commercial coupon dataset, was performed.

RESULTS

Two hundred thirty-seven unique drug products (≥1 claim) were identified. Factors that predicted for higher cost (P < .05) were branded products (105% more expensive than generics) and ultrapotent class (55% more expensive than low potency) while ointments predicted for lower cost (19% less expensive than creams). Cash prices remained relatively stable, except for ultrapotent branded topical corticosteroids (63% increase). Cost savings were available for both brand-to-generic ($14.75 per unit) and generic-to-generic ($6.82 per unit) switching. Coupon prices were consistently lower than cash prices (r = 0.89).

LIMITATIONS

Contracted rates through insurance plans were not included.

CONCLUSIONS

Topical corticosteroid prices over the past 5 years have stabilized, the exception being branded ultrapotent corticosteroids. Savings from switching among similar-strength substitutes remain significant despite price stabilization. Coupon prices mirror the hierarchy of cash prices and can help assess real-time costs.

Disseminated Superficial Porokeratosis: A Case Report

Disseminated superficial porokeratosis is a rare dermatological disorder characterized by annular keratotic lesions, presenting diagnostic challenges due to its variable clinical manifestations. The pathogenesis involves genetic predisposition and environmental factors, with mutations in the mevalonate pathway implicated. Despite its benign nature, this condition significantly impacts patients' quality of life, necessitating accurate diagnosis and effective therapeutic strategies. We present the case of a 45-year-old female with a three-year history of annular plaques on sun-exposed areas progressing to involve multiple body regions. The characteristic histopathological finding of coronoid lamellae confirmed the diagnosis of disseminated superficial porokeratosis. Treatment involved a multimodal approach, including topical corticosteroids, calcineurin inhibitors, and systemic retinoids, resulting in satisfactory clinical outcomes. Long-term follow-up emphasized the need for ongoing disease monitoring and patient education regarding sun protection. The presented case underscores the importance of recognizing characteristic histopathological features for accurate diagnosis and highlights the significance of long-term follow-up, disease monitoring, and patient education to optimize outcomes and enhance overall quality of life.

Safety and efficacy of Pimecrolimus in atopic dermatitis among Chinese infants: a sub-group analysis of a five-year open-label study

INTRODUCTION

Atopic dermatitis (AD) exhibits difference in immune polarization between Caucasians and Asian races due to which an evaluation of the efficacy and safety of Pimecrolimus (PIM) in Asian population is called for. The current study addresses the need via a sub-group analysis of the PETITE study (NCT00120523) to evaluate the safety and efficacy of PIM in Chinese infants.

MATERIALS AND METHODS

Patients with AD (≥3 months-<12 months of age) were randomized in a 1:1 ratio to either PIM 1% cream or topical corticosteroids (TCS). The primary endpoint was safety. The secondary endpoint was efficacy.

RESULTS

120 patients were randomized to either PIM 1% or TCS (n = 61 for PIM, n = 59 for TCS). The most often reported adverse events were reported by similar proportions of patients treated with PIM or TCS. There was a progressive increase in overall IGA treatment success in infants treated with PIM (82.9%, p < .05, 95% CI: 70.4, 95.3) after 26 weeks which was comparable to the TCS group (88.5%, p < .05, 95% CI: 79.8, 97.1).

CONCLUSION

PIM showed an early and sustained efficacy in the Chinese sub-population with a substantial corticosteroid-sparing effect in patients with AD.

Corticophobia among Parents of Children with Atopic Dermatitis: Assessing Major and Minor Risk Factors for High TOPICOP Scores

Corticophobia, fear of applying topical corticosteroids (TCSs), is a rising issue in industrialized countries, despite the actual safety of TCSs for atopic dermatitis (AD). Patients attending the Pediatric Dermatology Unit for skin examination were screened for AD. AD patients were included, and data were collected. Parental corticophobia was evaluated through the Topical Corticosteroid Phobia (TOPICOP) questionnaire. The χ2 test and logistic regression were used to analyze statistical associations between parental corticophobia (mild/moderate vs. severe) and patients' and parents' characteristics. Overall, 100 patients were included (53 females; 47 males; mean age 5.9 years): 44 had mild/moderate AD (EASI ≤ 21), and 56 had severe AD (EASI > 21) (mean EASI 19.7). Of the patients, 33 never consulted healthcare providers for AD, and 67 did. Parental education was low/intermediate in 60 cases and high (gymnasium/university degree) in 40. Mean parental DLQI was 10.7. Mean parental TOPICOP was 39.1%: 51 had mild/moderate corticophobia (TOPICOP ≤ 50%), and 49 had severe corticophobia (TOPICOP > 50%). At the χ2 test, corticophobia was associated with mild/moderate AD (OR 20.9487; 95% CI 7.2489-60.5402; p < 0.001), older age of patients (OR 4.1176; 95% CI 1.7880 to 9.4828; p < 0.001), early disease onset (OR 9.8925; 95% CI 2.7064-36.1596; p < 0.001), and previous healthcare professional consultations (OR 4.9279; 95% CI 1.9335-12.5597; p < 0.001). Also, severe parental corticophobia was very significantly associated with severe parental involvement of life quality (OR 33.3333; 95% CI 10.9046-101.8937; p < 0.001) and with high education of parents (gymnasium or university degree) (29/49) (OR 5.2727; 95% CI 2.1927-12.6790; p < 0.001). At logistic regression, high parental DLQI (p < 0.0001), high parental education (p < 0.0338), older age of patients (p = 0.0015), and early disease onset (p < 0.0513) accounted for major risk factors influencing severe parental corticophobia. Assessing risk factors for corticophobia is essential for addressing groups of parents at higher risk for corticophobia using educational programs, to overcome unfounded fears and augment treatment adherence.

Childhood guttate psoriasis: an updated review

Background

Guttate psoriasis is common and affects 0.5-2% of individuals in the paediatric age group. This review aims to familiarize physicians with the clinical manifestations, evaluation, diagnosis and proper management of guttate psoriasis.

Methods

A search was conducted in July 2023 in PubMed Clinical Queries using the key term "guttate psoriasis". The search strategy included all observational studies, clinical trials and reviews published within the past 10 years. The information retrieved from the search was used in the compilation of the present article.

Results

Guttate psoriasis typically presents with an abrupt onset of numerous, small, scattered, tear-drop-shaped, scaly, erythematous, pruritic papules and plaques. Sites of predilection include the trunk and proximal extremities. There may be a history of preceding streptococcal infection. Koebner phenomenon is characteristic. Guttate psoriasis may spontaneously remit within 3-4 months with no residual scarring, may intermittently recur and, in 40-50% of cases, may persist and progress to chronic plaque psoriasis. Given the possibility for spontaneous remission within several months, active treatment may not be necessary except for cosmetic purposes or because of pruritus. On the other hand, given the high rates of persistence of guttate psoriasis and progression to chronic plaque psoriasis, some authors suggest active treatment of this condition.

Conclusion

Various treatment options are available for guttate psoriasis. Triggering and exacerbating factors should be avoided if possible. Topical corticosteroids alone or in combination with other topical agents (e.g. tazarotene and vitamin D analogues) are the most rapid and efficient treatment for guttate psoriasis and are therefore the first-line treatment for mild cases. Other topical therapies include vitamin D analogues, calcineurin inhibitors, anthralin, coal tar and tazarotene. Ultraviolet phototherapy is the first-line therapy for moderate-to-severe guttate psoriasis, as it is more practical than topical therapy when treating widespread or numerous small lesions. Systemic immunosuppressive and immunomodulatory therapies (e.g. methotrexate, cyclosporine, retinoids, fumaric acid esters and biologics) may be considered for patients with moderate-to-severe guttate psoriasis who fail to respond to phototherapy and topical therapies.

Pimecrolimus 1% cream for mild-to-moderate atopic dermatitis: a systematic review and meta-analysis with a focus on children and sensitive skin areas

This systematic literature review (SLR) and meta-analysis assessed the efficacy and safety of pimecrolimus vs other topical treatments in patients with mild-to-moderate atopic dermatitis (AD), focusing on children and sensitive skin areas. An SLR was conducted in MEDLINE, Embase and Cochrane Library databases on January 15th, 2020, to identify randomized controlled trials (RCTs) with pimecrolimus as a study arm. Another SLR performed on October 5th, 2020 identified RCTs with a crisaborole study arm. Direct pair-wise meta-analysis was used to compare pimecrolimus with vehicle, tacrolimus or topical corticosteroids (TCS; n = 27 studies). Outcomes included Investigator's Global Assessment (IGA) score 0/1 up to week 6 and adverse events. Pimecrolimus was more efficacious than vehicle in achieving IGA 0/1 up to week 6 in children, and similar safety profiles were observed with pimecrolimus and vehicle in children and the mixed population, including on sensitive skin. No significant differences in efficacy and safety were observed between pimecrolimus and tacrolimus 0.03%. Efficacy and safety were similar for pimecrolimus and mild medium potency TCS; mildly potent steroids caused transient epidermal thinning in sensitive skin areas (not seen with pimecrolimus). Pimecrolimus can be considered as a first-line option for mild-to-moderate AD, particularly in children and sensitive skin areas.

A Review of Topical Roflumilast for the Treatment of Plaque Psoriasis

OBJECTIVE

This article reviews clinical trials to assess the efficacy, safety, and clinical application of once-daily roflumilast 0.3% cream for the treatment of plaque psoriasis.

DATA SOURCES

A systematic review of the literature was performed using the terms roflumilast OR Zoryve OR ARQ-151 in MEDLINE (PubMed) and EMBASE databases between January 2012 and October 2022. Bibliographies and the ClinicalTrials.gov website were also searched to identify further studies.

STUDY SELECTION AND DATA EXTRACTION

Studies written in English and relevant to pharmacology, clinical trials, and safety were considered for inclusion.

DATA SYNTHESIS

In two 8-week phase III clinical trials, disease severity as assessed by a score of "clear" or "almost clear" and a 2-point improvement on Investigator Global Assessment (IGA) was 42.4% and 37.5% at week 8 in DERMIS-1 and DERMIS-2, respectively, compared to 6.1% and 6.9% in the control groups. In the 52-week phase III trial, treatment success rates for plaque psoriasis and intertriginous psoriasis were similar to the 8-week data with 45% of patients in the treatment group were evaluated as an IGA of "clear" or "almost clear" at week 52.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS

Roflumilast is a new US Food and Drug Administration (FDA)-approved topical phosphodiesterase inhibitor that shows promise for the treatment of mild-severe plaque psoriasis. It is an effective and safe topical nonsteroidal alternative to currently available topical corticosteroids, but there are currently no comparative studies with other psoriasis treatments.

CONCLUSION

Roflumilast is effective and safe for the treatment of plaque psoriasis and intertriginous psoriasis. Future trials should compare its efficacy and tolerability with that of the older, clinically established topical corticosteroids. Prohibitive factors may include limited patient adherence to topical treatments and cost.

Corticosteroid-eluting implants for the management of chronic rhinosinusitis with or without nasal polyps

INTRODUCTION

Topical corticosteroid therapies are the most popular prescribed medications for patients with chronic rhinosinusitis (CRS). While topical corticosteroids effectively reduce the inflammatory burden associated with CRS, their distribution inside the nasal cavity is limited and primarily dependent on their delivery device. Corticosteroid-eluting implants serve as relatively novel technology, allowing targeted, sustained release of a high concentration of corticosteroids directly onto the sinus mucosa. Three types of corticosteroid-eluting implants can be characterized: 1. intraoperatively inserted corticosteroid-eluting sinus implants, 2. postoperatively inserted, office-based corticosteroid-eluting sinus implants, and 3. office-based corticosteroid-eluting implants for naïve paranasal sinuses.

AREAS COVERED

The review summarizes the different steroid-eluting sinus implants, their indications for use in CRS patients, and the existing evidence regarding their clinical efficacy. We also highlight potential areas for improvement and development.

EXPERT OPINION

Corticosteroid-eluting sinus implants highlight an evolving field that is constantly investigating and adding new treatment options to the market. Presently, corticosteroid-eluting implants for CRS are most commonly applied intraoperatively and postoperatively with endoscopic sinus surgery, providing significant improvements in mucosal healing and reducing the amount of surgical failures. Future development around corticosteroid-eluting implants should focus on strategies to reduce the amount of crusting around the implants.

Novel corticosteroid formulations in the treatment of eosinophilic esophagitis: what is the evidence?

Background and study aims

Eosinophilic esophagitis (EoE) is a food allergen-induced disease of the esophagus. Chronic, eosinophil-predominant inflammation eventually leads to fibrosis, esophageal dysfunction and severe morbidity. Swallowed topical corticosteroids (STCs) are a mainstay of anti-inflammatory therapy in the treatment of active EoE. Data on the efficacy of novel corticosteroid formulations, developed specifically for esophageal delivery, have recently become available.

Methods

A comprehensive review was performed aiming to summarize evidence on the role of STCs in the treatment of EoE. Two biomedical bibliographic databases (PubMED, EMBASE) were searched for articles providing original information on the efficacy and safety of STCs in adult EoE patients.

Results

Budesonide orodispersible tablet (BOT) and budesonide oral suspension (BOS) both surpassed placebo formulations regarding the efficacy of inducing and maintaining histologic, symptomatic and endoscopic remission. Overall, BOT displayed the highest grade of efficacy with clinico-histologic remission rates up to 75% after 1 year. Fluticasone propionate (APT-1011) achieved and maintained histologic and endoscopic responses in the majority of patients, whereas only a positive trend was demonstrated for symptomatic improvement. Mometasone and ciclesonide were studied in a limited number of smaller-scale trials and placebo-controlled data are required to substantiate the promising findings. All STCs displayed a similar side effects profile and were generally considered safe and well-tolerated.

Conclusions

Current evidence supports long-term treatment with novel corticosteroid formulations, challenging the established treatment paradigm of EoE. BOT appears to be the most effective steroid therapy, although head-to-head comparative trials between STCs are needed.

Loteprednol-Loaded Nanoformulations for Corneal Delivery by Quality-by-Design Concepts: Optimization, Characterization, and Anti-inflammatory Activity

Loteprednol etabonate (LE) is a topical corticosteroid that uses inflammatory conditions of the eye. It has a low ocular bioavailability and side effects such as corneal disorder, eye discharge, and ocular discomfort. Therefore, it was decided to select the delivery systems, which are solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC), and nanoemulsion (NE). Design of experiments (DoE) of SLN, NLC, and NE formulations were formulated by using the quality by design (QbD) approach. Precirol® ATO 5 and oleic acid were used as solid and liquid lipids, respectively, in SLN, NLC, and NE formulations. Physiochemical characterization was performed on the formulations. The optimized formulations' inflammatory effects have been appraised on human corneal epithelial cells employing the ELISA test. Physicochemical characterization studies and inflammatory effects were appraised. The sizes of optimized formulations of SLN, NLC, and NE were 86.19 nm, 82.38 nm, and 126.35 nm, respectively, with minimum polydispersity. The release behavior of the formulations is composed of both diffusion and erosion. ELISA test results proved that the formulations significantly reduced IL-1 and IL-6 levels (p < 0.05). D-optimal mixture experimental design allowed us to develop the most precise formulations of SLN, NLC, and NE. Furthermore, the optimized formulations could be promising candidates for treating an inflammation-based corneal disease of the eye.

Treatment of Olfactory Disorders After SARS - CoViD 2 Virus Infection

OBJECTIVE

The benefit of a nasal corticosteroid in the treatment of persistent post-infectious smell disorders is not as clear in previous studies as is assumed for olfactory training. This study would therefore like to describe the treatment strategies using the example of a persistent olfactory dysfunction as a result of a proven infection with SARS-CoViD-2-virus.

METHODS

Twenty patients (average age of 33.9 ± 11.9 years) with hyposmia were included in this study from December 2020 to July 2021. Every second patient received additionally a nasal corticosteroid. The two resulting randomized groups of equal size were screened with the TDI test, a 20-item taste powder test for the assessment of retronasal olfaction and otorhinolaryngological examination. The patients were asked to train twice daily using a standardized odor training kit and followed up after 2 months and 3 months, respectively.

RESULTS

We documented a significant overall improvement in olfactory ability over the investigation period in both groups. While the TDI score steadily increased on average under the combination therapy, the rise under olfactory training alone was initially steeper. This short-term interaction effect over mean two months was not statistically significant. According to Cohen, however, a moderate effect (eta2 = 0.055, Cohen`s d = 0.5) can still be assumed. This effect could be explained by a possibly higher compliance at the beginning of the sole olfactory training due to the lack of further drug treatment offers. When the training intensity decreases, the recovery of the sense of smell stagnates. Adjunctive therapy ultimately outweighs this short-term benefit.

CONCLUSIONS

The results reinforce the recommendation of early and consistent olfactory training on patients with dysosmia due to COVID-19. For continuous improvement of the sense of smell, an accompanying topical treatment seems at least to be worth consideration. The results should be optimized with larger cohorts and using new objective olfactometric methods.

A comparison of family physician and dermatologist topical corticosteroid prescriptions: A population-based cross-sectional study

BACKGROUND

Topical corticosteroids (TCS) are commonly prescribed to treat inflammatory skin diseases, and appropriate prescription is necessary for treatment success.

OBJECTIVE

To quantify differences between TCS prescribed by dermatologists at consultation and family physicians for patients treated for any skin condition.

METHODS

Using administrative health data in Ontario, we included all Ontario Drug Benefit recipients who filled at least one TCS prescription from a dermatologist at consultation and a family physician in the year prior between January 2014 and December 2019. We estimated mean differences and 95% confidence intervals in amount (in grams) and potency between the index dermatologist prescription and the highest and most recent family physician prescription amounts and potencies in the preceding year using linear mixed-effect models.

RESULTS

A total of 69,335 persons were included. The mean dermatologist amount was 34% larger than the highest amount and 54% larger than the most recent amount prescribed by family physicians. There were small but statistically significant differences in potency using established 7-category and 4-category potency classification systems.

CONCLUSIONS

Compared to family physicians, dermatologists prescribed substantially larger amounts and similarly potent TCS at consultation. Further research is needed to determine the effect of these differences on clinical outcomes.

Crusted Hyperkeratotic Scabies: A Case Report

Crusted scabies is a rare form of classic scabies characterized by severe symptoms, mainly observed in immunosuppressed patients. This disease has been associated with a variety of health problems, such as delayed diagnosis, infection risk, and high mortality, mainly from sepsis. We report the case of a patient with hyperkeratotic scabies in the context of immunosuppression associated with malnutrition and the use of topical corticosteroids. Ivermectin is critical for successfully treating crusted scabies. However, a higher cure rate has been reported with the combination of oral ivermectin and topical permethrin. In our study, we chose to use a plan suitable for grade two scabies, resulting in a subtotal regression of the lesions. Crusted scabies is a highly contagious parasitic cutaneous disease, and there are few reports in the national and international literature. It is necessary to suspect this presentation form in order to establish a timely diagnosis and detect and treat associated comorbidities.

Shedding light on key pharmacological knowledge and strategies for pediatric atopic dermatitis

INTRODUCTION

Atopic dermatitis (AD) is an inflammatory disease affecting over 20% of the pediatric population, with 85% of cases presenting before the age of five. Recently, therapeutic options in pediatric patients have evolved rapidly, following extensive development in adult treatments.

AREAS COVERED

This review will encompass relevant molecular drivers, along with an overlook on treatment modalities in pediatric AD, as well as a summary of pipeline treatments in clinical trials for pediatric patients from PubMed, Google Scholar, and Clinicaltrials.gov up to July 2022. Topical corticosteroids are the mainstay for AD flares in adults and children. Topical approved agents in pediatric AD are calcineurin inhibitors, crisaborolecrisaborole, and ruxolitinib. Dupilumab is the only FDA approved biologic for patients with AD from six months of age. A Janus kinase inhibitor, upadacitinib, is a systemic treatment approved for pediatric AD patients (age >12 years). Systemic immunosuppressants used in pediatric AD include methotrexate, azathioprine, cyclosporinecyclosporine, and mycophenolate mofetil.

EXPERT OPINION

Data regarding disease prevention are conflicting, however, an abundance of research has transpired regarding amelioration of symptoms and induction of disease clearance by targeting numerous pathological mechanisms. Understanding the pediatric AD phenotype will further advance the field and the development of improved therapeutics.

Topical corticosteroid phobia in adolescents with eczema and caregivers of children and adolescents with eczema: A cross-sectional survey

Steroid phobia is an increasing phenomenon that affects treatment adherence. The purpose of this study was to assess the prevalence and associated factors of steroid phobia among adolescents with eczema and the caregivers of children and adolescents with eczema by using questionnaires and TOPICOP© scale. The prevalence of steroid phobia is approximately 12% and 37% in the adolescent and caregiver groups, respectively. Caregivers who obtained information about topical corticosteroid (TCS) from dermatologists and whose children had fewer number of flares, demonstrated less concern about using TCS.

Risk factors of admission in school children with severe atopic dermatitis

There are no data about risk factor of admission and long-term (>1 year) prognosis of proactive therapy using topical corticosteroids (TCSs) in school children. This study aims to identify the prognosis of school children over 3 years treated with proactive therapy after hospitalization due to atopic dermatitis (AD). This retrospective cohort study used electronic medical record data of schoolchildren (aged 5-19 years) with a long-term admission program for AD at the National Center for Child Health and Development from January 2008 to December 2013. Long-term prognosis at 1 and 3 years after discharge were retrospectively identified from their medical records. The most common exacerbation factor was poor adherence (51.8%). At 1 and 3 years after hospitalization, 87.3% and 74.3%, respectively, of the children used TCSs on their trunk and limbs less than twice a week. Investigator's Global Assessment of AD scores were ≤1 for 81.0%and 75.7% at 1 and 3 years after discharge, respectively. AD was well-controlled during follow-up. Rehospitalization due to AD was observed in 11.8% children. Poor adherence was biggest risk factor for admission. Children with severe AD could achieve well-controlled AD with a long-term admission AD program and home-based proactive therapy using TCSs for 3 years after discharge. Maintaining good adherence for AD treatment is required to prevent exacerbation and improve future prognosis in school children. However, we need to engage for the children who required rehospitalization.

Photodynamic Therapy, Photobiomodulation and Acetonide Triamcinolone 0.1% in the Treatment of Oral Lichen Planus: A Randomized Clinical Trial

Objective: To evaluate the efficacy of photodynamic therapy (PDT) and photobiomodulation (PBM) in the treatment of oral lichen planus (OLP) in comparison with the use of topical corticosteroids. Material and methods: Sixty patients with OLP were randomized to three groups: group 1 photodynamic therapy applied once a week for four sessions, with orabase cream; group 2 low-power laser application with orabase cream; and group 3 inactive laser with triamcinolone acetonide 0.1%. Patient pain was evaluated, and the Thongprasom severity score, the Oral Health Impact Profile-14 (OHIP-14), and the Hamilton anxiety and depression scale at one and three months of follow-up. (ClinicalTrials.gov Identifier: NCT05127083). Results: Pain decreased significantly over time in all groups, though the symptoms relapsed over follow-up at one and three months in group 3. The OHIP-14 score improved significantly in groups 1 and 2 (p < 0.05), and this improvement was maintained after three months. Lesion resolution evaluated by the Thongprasom score at one month showed significant differences between groups 1 and 3 (p = 0.032) and between groups 2 and 3 (p = 0.024). Conclusions: Photodynamic therapy and photobiomodulation once a week for four weeks are safe and non-invasive treatment options, with the important advantage of lacking adverse effects. Further studies are needed to confirm it.

Topical Anti-Inflammatory Agents for Non-Infectious Uveitis: Current Treatment and Perspectives

Non-infectious uveitis represents a heterogenous group of immune-mediated ocular diseases, which can be associated with underlying systemic disease. While the initial choice of treatment of non-infectious uveitis depends on a number of factors such as anatomical location and degree of inflammation, topical therapies often remain the initial choice of non-invasive therapy. In this narrative review, we aim to describe the literature on non-infectious uveitis, with specific focus on the current perspective on topical anti-inflammatory therapy.

Why do some patients with vulval lichen sclerosus on long-term topical corticosteroid treatment experience ongoing poor quality of life?

OBJECTIVE

To identify reasons for ongoing poor quality of life (pQOL) in a subset of long-term topical corticosteroid-treated vulval lichen sclerosus (VLS) patients.

METHODS

A prospective cross-sectional study of patients attending a dermato-gynaecology practice in Sydney, Australia, comparing VLS patients with good quality of life (gQOL) and pQOL, in pre-treatment and long-term treatment groups, using the Vulval Quality of Life Index (VQLI). Demographics, VQLI scores and treatment characteristics were compared between gQOL and pQOL patients.

RESULTS

A total of 255 biopsy-proven VLS patients, 67 in pre-treatment and 188 in long-term treated groups were considered. There were 33 (49.3%) pQOL patients in pre-treatment and 13 (6.9%) in treatment groups (p < 0.001). The highest-scoring domain in treated pQOL patients was sexuality (1.7 [interquartile range (IQR) 1.0-2.0]), followed by anxiety [1.3 (IQR 1.0-1.5]), symptoms (1.0 [IQR 0.5-1.5]) and activities of daily living (0.7 [IQR 0.3-1.0]). Compared to treated gQOL, treated pQOL had significantly higher proportions of patients with partial treatment adherence (8 [61.5%] vs 42 [24.0%], p = 0.006), suboptimal disease control (7 [53.8%] vs 20 [11.4%], p < 0.001), scarring progression (3 [23.1%] vs 7 [4.0%], p = 0.024) and urinary incontinence (5 [38.5%] vs 27 [15.4%], p = 0.049).

CONCLUSIONS

Only a minority of long-term treated VLS patients reported ongoing pQOL. Of those who did, sexuality and anxiety domains were found to be the main sources of distress. Three major areas distinguishing gQOL from pQOL patients were (1) treatment adherence and disease control, (2) psychological factors and (3) urinary incontinence.

Management of pediatric pemphigus vulgaris with rituximab: A case report and review of the literature

Pemphigus vulgaris (PV), an acquired autoimmune bullous disease, is caused by autoantibodies targeting desmosomal proteins in the skin and mucous membranes. Recent data from the adult PV population supports the use of rituximab, a chimeric anti-CD20 IgG1 antibody, as a primary treatment strategy, but limited data exist regarding treatment in the pediatric population. We report the case of a 13-year-old male with PV treated successfully with systemic corticosteroids and rituximab, and review the literature supporting the treatment of pediatric PV with rituximab.

Patches as Polymeric Systems for Improved Delivery of Topical Corticosteroids: Advances and Future Perspectives

Mucoadhesive polymer patches are a promising alternative for prolonged and controlled delivery of topical corticosteroids (CS) to improve their biopharmaceutical properties (mainly increasing local bioavailability and reducing systemic toxicity). The main biopharmaceutical advantages of patches compared to traditional oral dosage forms are their excellent bioadhesive properties and their increased drug residence time, modified and unidirectional drug release, improved local bioavailability and safety profile, additional pain receptor protection, and patient friendliness. This review describes the main approaches that can be used for the pharmaceutical R&D of oromucosal patches with improved physicochemical, mechanical, and pharmacological properties. The review mainly focuses on ways to increase the bioadhesion of oromucosal patches and to modify drug release, as well as ways to improve local bioavailability and safety by developing unidirectional -release poly-layer patches. Various techniques for obtaining patches and their influence on the structure and properties of the resulting dosage forms are also presented.

Fitting Pharmacodynamic Data to the Emax Model to Assess the Inherent Potency of Topical Corticosteroids

The widespread use of topical corticosteroids (TCs) in dermatotherapy requires a consideration of their potency and benefit/risk ratios. Although there are a variety of topical corticosteroid products (TCPs) available on the market and their potencies are ranked using different classification systems, to our knowledge, no classification system to rank the inherent potencies of TC active pharmaceutical ingredients (APIs) currently exists. Most of the published classification systems for TCPs are based on randomized clinical comparative studies and/or vasoconstrictor assay (VCA) data. The objective was to apply the US FDA's VCA to classify the inherent potencies of several TCs using standardized doses to make appropriate comparisons of the relevant APIs in solutions of the same molar concentrations. Six TC APIs were assessed for their relative potencies using healthy human participants. The E_max model was used to fit skin blanching data following application of the respective TCs, and the parameters, E_max and ED₅₀, were derived. E_max values were used as the metric to assess potency. Statistical analyses of the data revealed that the inherent potencies of fluticasone propionate, mometasone furoate, and hydrocortisone butyrate were similar. However, there was no significant difference between hydrocortisone butyrate and clobetasol propionate, while there was a significant difference between clobetasol propionate, fluticasone propionate, and mometasone furoate. Hence, the potency of hydrocortisone butyrate appears to overlap two potency classes. Furthermore, the potencies of betamethasone valerate and methylprednisolone aceponate were similar but lower than those of all of the other APIs. The application of the VCA to classify inherent potency provides a reliable method to establish a classification system for TCs. Inherent potency assessment of TCs provides information that will be useful when choosing an appropriate TC for the development of a TCP for a specific clinical indication.

Characterization of acne associated with upadacitinib treatment in patients with moderate-to-severe atopic dermatitis: a post hoc integrated analysis of three phase 3 randomized, double-blind, placebo-controlled trials

BACKGROUND

Acne is the most frequent adverse event (AE) associated with upadacitinib treatment in patients with moderate-to-severe atopic dermatitis (AD).

OBJECTIVE

To characterize the AE of acne associated with upadacitinib.

METHODS

This was a post hoc integrated analysis of three phase 3 randomized, double-blind, placebo-controlled trials of upadacitinib, alone (NCT03569293 and NCT03607422) or in combination with topical corticosteroids (NCT03568318). Data included were from the 16-week placebo-controlled period.

RESULTS

Over 16 weeks, 84/857 (9.8%), 131/864 (15.2%), and 19/862 (2.2%) patients randomized to receive upadacitinib 15 mg, upadacitinib 30 mg, and placebo, respectively, experienced acne. All cases of acne, except 1, were mild/moderate in severity; 2 patients discontinued treatment due to moderate acne. Acne occurred at higher rates among younger, female, and non-White patients. Acne required no intervention in 40.5% and 46.6% of patients receiving upadacitinib 15 or 30 mg, respectively; most remaining cases were managed with topical antibiotics, benzoyl peroxide, and/or retinoids. Acne also had no impact on patient-reported outcomes.

LIMITATIONS

This study was relatively short in duration and had a small patient population.

CONCLUSIONS

Acne associated with upadacitinib for AD treatment is usually mild/moderate in severity and managed with topical therapies or no intervention.

Development of Lipid Nanoparticles for Transdermal Loteprednol Etabonate Delivery

AIM

Loteprednol etabonate (LE) is a new generation corticosteroid that is used for the treatment of inflammatory and allergic conditions of the eye. Therefore, solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) were attempted to improve for transdermal LE delivery for the first time.

METHODS

SLN and NLC were produced by hot homogenization and ultrasonication technique. Their physical stability was monitored for 3 months of storage. Drug release and permeation of SLN and NLC through the porcine skin were investigated.

RESULTS

It was determined that SLN and NLC mean particle size as 139.1 nm had a homogeneous particle size distribution (∼0,169 PI) and mean charge as -23.6. They were found to be stable both physically and chemically at room temperature.

CONCLUSION

SLN and NLC formulations of LE can be stated among the systems that can be an alternative to conventional systems with less side-effect in the treatment of inflammatory problems.

Budesonide orodispersible tablets for induction of remission in patients with active eosinophilic oesophagitis: A 6-week open-label trial of the EOS-2 Programme

Background

A novel budesonide orodispersible tablet (BOT) has been proven effective in adult patients with active eosinophilic oesophagitis (EoE) in a 6‐week placebo‐controlled trial (EOS‐1).

Aims

To report the efficacy of an open‐label induction treatment with BOT in a large prospective cohort of EoE patients within the EOS‐2 study.

Methods

Patients with clinico‐histological active EoE were treated with BOT 1 mg BID for 6 weeks. The primary endpoint was clinico‐histological remission (≤2 points on numerical rating scales [0–10] each for dysphagia and odynophagia, and peak eosinophil count <16 eos/mm² hpf (corresponds to <5 eos/hpf)). Further study endpoints included clinical and histological remission rates, change in the EEsAI‐PRO score, change in peak eosinophil counts, and deep endoscopic remission using a modified Endoscopic Reference Score.

Results

Among 181 patients enrolled, 126 (69.6%) achieved clinico‐histological remission (histological remission 90.1%, clinical remission 75.1%). The mean peak eosinophil counts decreased by 283 eos/mm² hpf (i.e., by 89.0%). Mean EEsAI‐PRO score decreased from baseline by 29 points and deep endoscopic remission was achieved in 97 (53.6%) patients. The majority of patients judged tolerability as good or very good (85.6%) and compliance was high (96.5%). Local candidiasis was suspected in 8.3% of patients; all were of mild severity, resolved with treatment and none led to premature withdrawal from the study.

Conclusions

In this large prospective trial, a 6‐week open‐label treatment with BOT 1 mg BID was highly effective and safe in achieving clinico‐histological remission of active EoE and confirmed the results of the placebo‐controlled EOS‐1 trial.

A phase 3 randomized, multicenter, double-blind study to evaluate the safety of upadacitinib in combination with topical corticosteroids in adolescent and adult patients with moderate-to-severe atopic dermatitis in Japan (Rising Up): An interim 24-week analysis

BACKGROUND

Systemic atopic dermatitis treatments that have acceptable safety are needed.

OBJECTIVE

To evaluate the safety of the oral Janus kinase inhibitor upadacitinib in combination with topical corticosteroids (TCSs) for the treatment of atopic dermatitis.

METHODS

In this phase 3, double-blind study (Rising Up), Japanese patients (12-75 years) with moderate-to-severe atopic dermatitis were randomized in a 1:1:1 ratio to receive 15 mg of upadacitinib + TCS, 30 mg of upadacitinib + TCS, or a placebo + TCS (rerandomized in a 1:1 ratio to receive either 15 or 30 mg of upadacitinib + TCS at week 16). Adverse events and laboratory data were assessed for safety.

RESULTS

In 272 treated patients, the serious adverse event rates were similar for 15- and 30-mg upadacitinib + TCS at week 24 (15 mg, 56%; 30 mg, 64%) but greater than those for placebo + TCS (42%). Acne (all mild or moderate; none leading to discontinuation) occurred more frequently with upadacitinib + TCS (15 mg, 13.2%; 30 mg, 19.8%) than with placebo + TCS (5.6%). Furthermore, herpes zoster infection (4.4% vs 0%), anemia (1.1% vs 0%), neutropenia (4.4% vs 1.1%), and creatine phosphokinase elevations (2.2% vs 1.1%) occurred more frequently with 30-mg upadacitinib + TCS than with 15-mg upadacitinib + TCS; none of these events were reported with placebo + TCS. No thromboembolic events, malignancies, gastrointestinal perforations, active tuberculosis, or deaths occurred.

LIMITATIONS

The limitations included a small sample size and short observation period as well as nongeneralizability of the results beyond Japanese populations.

CONCLUSIONS

The results were generally consistent with those of previous reports; no new safety risks were detected.

Technologies for Type 1 Diabetes and Contact Dermatitis: Therapeutic Tools and Clinical Outcomes in a Cohort of Pediatric Patients

The increasing use of technological devices for the management of diabetes is related to the prolonged exposure of patients' skin to chemical and mechanical agents and, consequently, to the increased risk of developing dermatological complications. Among these, contact dermatitis is the most insidious skin disorder. Despite the magnitude of the issue, no universally accepted recommendations on the management of this common complication are currently available. Our observational study aimed to describe all the solutions adopted by patients and their caregivers to treat and prevent the appearance of contact dermatitis and to describe the clinical impact of this cutaneous complication. Twenty-one pediatric patients (mean age 12.1 ± 3.7 years) with type 1 diabetes were recruited in the study. The most common treatment used to treat acute skin lesions was the application of topical corticosteroids, sometimes associated with topical antibiotics (9.5%). In order to prevent the further appearance of dermatitis, the most frequently adopted measure was the use of hydrocolloid and/or silicone-based adhesives, followed by the application of protective barrier films. One patient reported benefit from the off-label use of fluticasone propionate nasal spray. However, only 52.4% of the study participants achieved a definitive resolution of the skin issue, and 38.1% of patients were forced to discontinue insulin pump therapy and/or continuous glucose monitoring. No differences were observed in glycated hemoglobin values between the period before and after the onset of contact dermatitis. Our study confirms the severity of this dermatological complication that may hinder the spread of new technologies for the management of diabetes. Finally, our findings highlight the importance of establishing close collaboration both with pediatric allergy specialists to prescribe the most suitable treatment and with manufacturing companies to ensure that adhesives of technological devices are free of harmful well-known sensitizers.

Novel Predictive Model for Adrenal Insufficiency in Dermatological Patients with Topical Corticosteroids Use: A Cross-Sectional Study

Purpose

This study aimed to identify predictive factors and to develop a predictive model for adrenal insufficiency (AI) related to topical corticosteroids use.

Methods

The research was conducted using a cross-sectional design. Adult patients with dermatological conditions who had been prescribed topical steroids for at least 12 months by the dermatology outpatient departments of the Faculty of Medicine, Chiang Mai University from June through October 2020 were included. Data on potential predictors, including baseline characteristics and laboratory investigations, were collected. The diagnoses of AI were based on serum 8AM cortisol and low-dose ACTH stimulation tests. Multivariable logistic regression was used for the derivation of the diagnostic score.

Results

Of the 42 patients, 17 (40.5%) had AI. The statistically significant predictive factors for AI were greater body surface area of corticosteroids use, age <60 years, and basal serum cortisol <7 µg/dL. In the final predictive model, duration of treatment was added as a factor based on its clinical significance for AI. The four predictive factors with their assigned scores were: body surface area involvement 10–30% (20), >30% (25); age <60 years old (15); basal serum cortisol of <7 µg/dL (30); and duration of treatment in years. Risk of AI was categorized into three groups, low, intermediate and high risk, with total scores of <25, 25–49 and ≥50, respectively. The predictive performance for the model was 0.92 based on area under the curve.

Conclusion

The predictive model for AI in patients using topical corticosteroids provides guidance on the risk of AI to determine which patients should have dynamic ACTH stimulation tests (high risk) and which need only close follow-up (intermediate and low risk). Future validation of the model is warranted.

Influence of topical corticosteroids on malignant transformation of oral lichen planus

BACKGROUND

Oral lichen planus (OLP) is considered an oral potentially malignant disorder. While OLP has been associated with the development of oral squamous cell carcinoma (OSCC), little is known about the role of topical corticosteroids therapy (TCT) in the promotion of carcinogenesis. The study aimed to determine if TCT influences the time of malignant transformation of OLP to OSCC. The study also investigates this correlation in the presence or absence of Candida overgrowth, and in the context of conventional OSCC risk factors such as smoking, alcohol use, and male gender.

METHODS

A retrospective analysis of electronic health records at a tertiary care academic medical center was performed. Patients with OLP and OSCC were considered for inclusion. The diagnosis of OLP required both clinical and histological documentation.

RESULTS

Eighty-two patients met inclusion criteria, consisting of 48 women (58.25%) and 34 men (41.5%) and the mean patient age was 65.9 years (SD = 13.25). Forty-five patients (54.9%) received TCT for OLP before they developed OSCC. The time between the OLP and OSCC diagnoses increased by four years in patients who received topical steroid therapy for OLP (p < 0.001) and decreased by three years (p = 0.010) in those with Candida overgrowth. Gender, smoking, and alcohol use did not have a statistically significant influence on the time between OLP and OSCC.

CONCLUSION

The management of OLP using TCT potentially delayed cancer development in our study. Conversely, it appears that Candida may play a role in the field cancerization of OLP patients.
