Association Between Topical Corticosteroid Use and Type 2 Diabetes in Two European Population-Based Adult Cohorts

Evaluating Efficacy and Safety of Crisaborole in Managing Childhood Mild to Moderate Atopic Dermatitis: A Systematic Review and Meta-Analysis

Aims/Background Atopic dermatitis (AD) is a common chronic inflammatory skin disorder globally. Crisaborole, a nonsteroidal topical phosphodiesterase 4 inhibitor (PDE4i), has been utilized in treating AD. Crisaborole regulates the production of inflammatory cytokines, which are usually overactive among AD patients. Therefore, this study aimed to explore the efficacy and safety of crisaborole in treating AD in patients aged ≤18 years. Methods A literature search was performed across PubMed, MEDLINE, Embase, Cochrane, and Google Scholar. The inclusion criteria involved primary studies evaluating the effect of crisaborole in treating dermatitis, articles exploring the use of crisaborole in AD patients below 18 years (>two years), and articles published in English between 2000 and 2022. However, the studies evaluating AD in adult patients, those reporting treatments other than crisaborole, those published before 2000, and articles written in languages other than English were excluded from this analysis. Furthermore, secondary data sources such as case reports, newspaper articles, magazines, and other systematic reviews and meta-analyses were excluded. A meta-analysis was conducted using RevMan 5.4. The risk of bias in the manuscripts was assessed using the Cochrane tool. The I-square test statistic was used to determine heterogeneity, and Egger's test was used to evaluate publication bias. Results Ten studies met the eligibility criteria and were included in the final analysis. Most of the studies exhibited a low risk of bias with no publication bias. Meta-analysis indicated a significant difference in the number of patients attaining Investigator Static Global Assessment (ISGA) success at day 29, with significantly higher patients in the crisaborole group than in the vehicle group (odds ratio (OR) 1.56, 95% CI 1.24 to 1.96; I2 = 77%; p = 0.0001). Similarly, pruritus improvement was significant between the two cohorts at day 29, indicating significantly higher heterogeneity (OR 1.70, 95% CI 1.10 to 2.63; I2 = 91%; p = 0.02). Furthermore, the safety profiling of the treatments was insignificant, demonstrating no statistical difference in the treatment-emergent adverse events (TEAEs) between the two groups with high heterogeneity (OR 0.53, 95% CI 0.14 to 1.98; I2 = 99%; p = 0.35). Conclusion Crisaborole demonstrates substantial efficacy in treating mild to moderate AD compared to vehicle therapies, as it reduces the signs and symptoms of the disease. Furthermore, crisaborole is well tolerated and has an acceptable safety profile in treating mild to moderate AD patients.

Prevalence and clinical impact of topical corticosteroid phobia among patients with chronic hand eczema-Findings from the Danish Skin Cohort

BACKGROUND

Topical corticosteroid phobia (TOPICOP) is associated with poor treatment adherence and is common among patients with skin disease. Knowledge about corticosteroid phobia and treatment adherence among patients with chronic hand eczema (CHE) is limited.

OBJECTIVES

To investigate patient-reported outcomes regarding topical corticosteroids (TCSs), and their impact on treatment adherence in patients with CHE.

METHODS

Patients with CHE from the Danish Skin Cohort answered a questionnaire including the TOPICOP scale and Medication Adherence Report Scale. Response rate was 69.2%.

RESULTS

Of 927 with CHE, 75.5% totally or almost agreed that TCS damage the skin, 48.9% totally or almost agreed that TCS would affect their future health and 36.3% reported some degree of fear of TCS although they were unaware of any TCS-associated risks. Most patients (77.9%) always or often stop treatment as soon as possible, whereas 54.8% always or often wait as long as possible before starting treatment. Overall, 38.8% reported that they had taken less medicine than prescribed and 54.0% had stopped treatment throughout a period. Treatment adherence decreased with increasing corticosteroid phobia (P = .004).

LIMITATIONS

TOPICOP has not been validated in patients with CHE.

CONCLUSIONS

Corticosteroid phobia is common among patients with CHE and negatively associated with treatment adherence.

Is It Time for a New Algorithm for the Pharmacotherapy of Steroid-Induced Diabetes?

Glucocorticoids (GS) are widely used in multiple medical indications due to their anti-inflammatory, immunosuppressive, and antiproliferative effects. Despite their effectiveness in treating respiratory, skin, joint, renal, and neoplastic diseases, they dysregulate glucose metabolism, leading to steroid-induced diabetes (SID) or a significant increase of glycemia in people with previously diagnosed diabetes. The risk of adverse event development depends on the prior therapy, the duration of the treatment, the form of the drug, and individual factors, i.e., BMI, genetics, and age. Unfortunately, SID and steroid-induced hyperglycemia (SIH) are often overlooked, because the fasting blood glucose level, which is the most commonly used diagnostic test, is insufficient for excluding both conditions. The appropriate control of post-steroid hyperglycemia remains a major challenge in everyday clinical practice. Recently, the most frequently used antidiabetic strategies have been insulin therapy with isophane insulin or multiple injections in the basal-bolus regimen. Alternatively, in patients with lower glycemia, sulphonylureas or glinides were used. Taking into account the pathogenesis of post-steroid-induced hyperglycemia, the initiation of therapy with glucagon-like peptide 1 (GLP-1) analogs and dipeptidyl peptidase 4 (DPP-4) inhibitors should be considered. In this article, we present a universal practical diagnostic algorithm of SID/SIH in patients requiring steroids, in both acute and chronic conditions, and we present a new pharmacotherapy algorithm taking into account the use of all currently available antidiabetic drugs.

Medication-Induced Hyperglycemia and Diabetes Mellitus: A Review of Current Literature and Practical Management Strategies

With the increasing global incidence of diabetes mellitus, physicians may encounter more patients with acute and chronic complications of medication-induced hyperglycemia and diabetes. Moreover, medication-induced diabetes may be an important contributing factor to the high rates of diabetes, and recognizing its impact and risk is a critical step in curtailing its effect on the global population. It has long been recognized that multiple classes of medications are associated with hyperglycemia through various mechanisms, and the ability to foresee this and implement adequate management strategies are important. Moreover, different antihyperglycemic medications are better suited to combat the hyperglycemia encountered with different classes of medications, so it is critical that physicians can recognize which agents should be used, and which medications to avoid in certain types of medication-induced hyperglycemia. In this review, we will discuss the evidence behind the main classes of medications that cause hyperglycemia, their mechanism of action, specific agents that are associated with worsened glycemic control, and, most importantly, management strategies that are tailored to each specific class.

Higher cumulative dose of topical corticosteroids is associated with osteoporosis and major osteoporotic fracture: A nationwide case-control study

BACKGROUND

Connections between long-term use of topical corticosteroids (TCSs) of varying potency and osteoporosis and major osteoporotic fracture (MOF) are unclear. Susceptibility to adverse bone effects of TCSs in different sex, age and ethnic groups is unknown too.

OBJECTIVES

To demonstrate the association between cumulative dose of TCSs of varying potency and osteoporosis and MOF in Taiwanese population, with stratified analysis of sex and age.

METHODS

We conducted a nationwide case-control study and obtained data from Taiwan National Health Insurance Research Database. Cumulative TCS doses in different exposure periods were calculated, and the potency of TCSs was converted to prednisolone equivalent. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for osteoporosis and MOF associated with TCS use.

RESULTS

From 2017 to 2020, 129,682 osteoporosis cases and 34,999 MOF cases were selected and randomly matched with 518,728 and 139,996 controls by sex and age. We found clear dose-response relationships between long-term TCS exposure and osteoporosis and MOF. For example, compared to no TCS use, adjusted ORs of osteoporosis were 1.216 (95% CI 1.189-1.243), 1.260 (95% CI, 1.241-1.280) and 1.341 (95% CI, 1.314-1.369) for exposure to low, medium and high cumulative TCS doses, respectively, over 5 years. Adjusted ORs of MOF were 1.118 (95% CI 1.069-1.170), 1.191 (95% CI, 1.156-1.227) and 1.288 (95% CI, 1.238-1.340) for exposure to low, medium and high cumulative TCS doses, respectively, over 5 years. Stratified analysis showed women had higher ORs of osteoporosis and MOF compared to men. Younger people (<50 years) had highest OR of osteoporosis compared to other age groups.

CONCLUSIONS

Higher cumulative TCS dose was associated with increased risk of osteoporosis and MOF. Long-term use of TCSs should be cautious, especially in susceptible populations such as women and young people.

Interplay between diabetes mellitus and atopic dermatitis

Inflammatory dermatoses such as atopic dermatitis (AD) have long been linked to the pathogenesis of diabetes mellitus. Indeed, numerous studies show an increased risk of diabetes mellitus in individuals with AD although lower prevalence of diabetes mellitus is also observed in few studies. Though the underlying mechanisms accounting for the reciprocal influence between these two conditions are still unclear, the complex interplay between diabetes mellitus and AD is attributable, in part, to genetic and environmental factors, cytokines, epidermal dysfunction, as well as drugs used for the treatment of AD. Proper management of one condition can mitigate the other condition. In this review, we summarize the evidence of the interaction between diabetes mellitus and AD, and discuss the possible underlying mechanisms by which these two conditions influence each other.

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.

Treating the Side Effects of Exogenous Glucocorticoids; Can We Separate the Good From the Bad?

It is estimated that 2% to 3% of the population are currently prescribed systemic or topical glucocorticoid treatment. The potent anti-inflammatory action of glucocorticoids to deliver therapeutic benefit is not in doubt. However, the side effects associated with their use, including central weight gain, hypertension, insulin resistance, type 2 diabetes (T2D), and osteoporosis, often collectively termed iatrogenic Cushing's syndrome, are associated with a significant health and economic burden. The precise cellular mechanisms underpinning the differential action of glucocorticoids to drive the desirable and undesirable effects are still not completely understood. Faced with the unmet clinical need to limit glucocorticoid-induced adverse effects alongside ensuring the preservation of anti-inflammatory actions, several strategies have been pursued. The coprescription of existing licensed drugs to treat incident adverse effects can be effective, but data examining the prevention of adverse effects are limited. Novel selective glucocorticoid receptor agonists and selective glucocorticoid receptor modulators have been designed that aim to specifically and selectively activate anti-inflammatory responses based upon their interaction with the glucocorticoid receptor. Several of these compounds are currently in clinical trials to evaluate their efficacy. More recently, strategies exploiting tissue-specific glucocorticoid metabolism through the isoforms of 11β-hydroxysteroid dehydrogenase has shown early potential, although data from clinical trials are limited. The aim of any treatment is to maximize benefit while minimizing risk, and within this review we define the adverse effect profile associated with glucocorticoid use and evaluate current and developing strategies that aim to limit side effects but preserve desirable therapeutic efficacy.

Incidence of Cardiovascular Disease and Venous Thromboembolism in Patients With Atopic Dermatitis

BACKGROUND

Atopic dermatitis (AD) may increase risk for atherothrombotic and cardiovascular (CV) disease.

OBJECTIVE

Determine CV disease and venous thromboembolism risk among patients with AD.

METHODS

Cohort study using electronic health data from U.K. general practices in 1994 to 2015. Children (<18 y) and adults (≥18 y) with AD were matched to patients without AD on age, same practice, and encounter date. Treatments and specialist referrals served as proxies of AD severity. Outcomes were incident myocardial infarction, cerebrovascular accident (CVA), diabetes, hypertension, dyslipidemia, deep vein thrombosis (DVT), and pulmonary embolism. Cox regression analysis was used to compare outcomes in AD versus non-AD patients.

RESULTS

Comparing 409,341 children with AD (93.2% mild, 5.5% moderate, and 1.3% severe) to 1,809,029 unaffected children, AD was associated with higher risk of DVT (hazard ratio [HR] 1.23; 95% confidence interval [95% CI] 1.02-1.48) and severe AD was associated with higher risk of CVA (HR 2.43; 95% CI 1.13-5.22) and diabetes (HR 1.46; 95% CI 1.06-2.01). Comparing 625,083 adults with AD (65.7% mild, 31.4% moderate, and 2.9% severe) to 2,678,888 unaffected adults, AD, especially when severe, was associated with higher risk of DVT (HR 1.14; 95% CI 1.11-1.18; and HR 1.64; 95% CI 1.49-1.82, respectively) and small but increased risks of CVA, diabetes, and dyslipidemia. Adults with severe AD had higher risk of myocardial infarction (HR 1.27; 95% CI 1.15-1.39), CVA (HR 1.21; 95% CI 1.13-1.30), diabetes (HR 1.15; 95% CI 1.09-1.22), dyslipidemia (HR 1.11; 95% CI 1.06-1.17), and pulmonary embolism (HR 1.39; 95% CI 1.21-1.60) compared with adults without AD.

CONCLUSIONS

Atopic dermatitis, particularly when severe, is associated with small but increased risks of CV risk factors and events and significantly increased risk of venous thromboembolism.

Guidelines of care for the management of atopic dermatitis in adults with topical therapies

BACKGROUND

New evidence has emerged since the 2014 guidelines that further informs the management of atopic dermatitis (AD) with topical therapies. These guidelines update the 2014 recommendations for management of AD with topical therapies.

OBJECTIVE

To provide evidence-based recommendations related to management of AD in adults using topical treatments.

METHODS

A multidisciplinary workgroup conducted a systematic review and applied the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) approach for assessing the certainty of evidence and formulating and grading recommendations.

RESULTS

The workgroup developed 12 recommendations on the management of AD in adults with topical therapies, including nonprescription agents and prescription topical corticosteroids (TCS), calcineurin inhibitors (TCIs), Janus kinase (JAK) inhibitors, phosphodiesterase-4 inhibitors (PDE-4), antimicrobials, and antihistamines.

LIMITATIONS

The pragmatic decision to limit the literature review to English-language randomized trials may have excluded data published in other languages and relevant long-term follow-up data.

CONCLUSIONS

Strong recommendations are made for the use of moisturizers, TCIs, TCS, and topical PDE-4 and JAK inhibitors. Conditional recommendations are made for the use of bathing and wet wrap therapy and against the use of topical antimicrobials, antiseptics, and antihistamines.

Effects of topical corticosteroid versus tacrolimus on insulin sensitivity and bone homeostasis in adults with atopic dermatitis-A randomized controlled study

INTRODUCTION

Topical corticosteroids (TCS), used to treat atopic dermatitis (AD), have been associated with type 2 diabetes and osteoporosis in epidemiological studies, possibly explained by systemic absorption.

OBJECTIVES

We examined whether intensive daily whole-body TCS treatment over 2 weeks followed by twice weekly application for 4 weeks could elicit insulin resistance and increase bone resorption in adults with AD.

METHODS

A randomized parallel-group double-blind double-dummy non-corticosteroid-based active comparator study design was completed in Copenhagen, Denmark. Thirty-six non-obese, non-diabetic adults with moderate-to-severe AD were randomized to whole-body treatment with betamethasone 17-valerate 0.1% plus a vehicle once daily or tacrolimus 0.1% twice daily after washout. Insulin sensitivity assessed by the hyperinsulinemic-euglycemic clamp combined with tracer infusions and biomarkers of bone formation (P1NP) and resorption (CTX) were evaluated at baseline, after 2 weeks of daily treatment and after further 4 weeks of twice-weekly maintenance treatment.

RESULTS

AD severity improved with both treatments and systemic inflammation was reduced. After 2 weeks, we observed similar increase in peripheral insulin sensitivity with use of betamethasone (n = 18) and tacrolimus (n = 18). Bone resorption biomarker, CTX, was unchanged, while bone formation marker, P1NP, decreased after betamethasone treatment after both 2 and 6 weeks but remained unchanged in the tacrolimus arm.

CONCLUSIONS

Whole-body treatment with TCS leads to systemic exposure but appears not to compromise glucose metabolism during short-term use, which may be a result of reduced systemic inflammatory activity. The negative impact on bone formation could be regarded an adverse effect of TCS.

Topical Glucocorticoid Use and the Risk of Posttransplant Diabetes

Systemically administered glucocorticoids constitute an essential part of the immunosuppressive regimen for transplant recipients, yet their known risks of causing hyperglycemia or posttransplant diabetes require close monitoring and minimisation of use, when possible, to prevent detrimental effects on patient morbidity and graft survival. Topical glucocorticoids, on the other hand, are rarely considered to affect glucose metabolism and therefore seldomly monitored, despite their wide and in some cases, long-term use. We report a case of a renal transplant recipient presenting with acute hyperosmolar hyperglycemia after treatment with topical glucocorticoids and present a mini review of the literature.

Comorbidities of atopic dermatitis-what does the evidence say?

Atopic dermatitis (AD) is a common disease that is associated with atopic and nonatopic comorbidities. There has been a growing interest in this area of AD, because presence or risk of comorbidities can in many ways impact the management of patients with AD. Thus, some treatments for AD may improve its comorbidities as well, whereas others may increase their risk. In this review article, we discuss various comorbidities of AD mostly on the basis of the results of recent multiple systematic reviews and meta-analyses to update readers about this rapidly developing area of dermatology. We emphasize the important information provided by studies presenting both relative risk and absolute risk, and show that AD is associated with, among others, atopic comorbidities such as asthma, rhinitis, and food allergy, nonatopic comorbidities such as ocular, psychiatric, infectious, endocrine, autoimmune, and cardiovascular diseases, and certain cancers. Clinicians need to be aware of these and be cognizant about positive and negative effects of existing and new treatments for AD.

Complications of Corticosteroid Therapy: A Comprehensive Literature Review

Relevance to Patient Care and Clinical Practice: Corticosteroids are among the most prescribed medications, particularly during the COVID-19 era. The literature has clearly highlighted the dangers of prolonged, high-dose corticosteroid use, which is important for clinicians to consider before treating patients in their clinical practices. Objective: The objective of this article is to review the literature on complications of corticosteroid use, review corticosteroid pharmacokinetics, and provide an updated reference on risks associated with corticosteroid therapy, especially at higher doses. Data Sources: A conventional literature search of PubMed was conducted without restrictions on publication date. Search terms included "corticosteroids," "avascular necrosis," "gastrointestinal bleeding," and "complications." Study Selection and Data Extraction: Pertinent systematic review/meta-analyses and randomized controlled trials were reviewed for study inclusion. Data Synthesis: Corticosteroids were associated with complications including avascular necrosis, gastrointestinal bleeding, myocardial infarction, heart failure, cerebrovascular events, diabetes mellitus, psychiatric syndromes, ophthalmic complications, tuberculosis reactivation, and bacterial sepsis. Increased daily and cumulative doses were associated with increased excess risk of complications. Cumulative doses greater than 430 mg prednisone equivalent were shown to increase the excess risk of avascular necrosis, with progressively higher rates with higher doses. Risk of gastrointestinal bleeding was significantly increased with corticosteroid usage in the in-patient but not out-patient setting. Conclusion: Since corticosteroids have been associated with the aforementioned severe complications and frequent medicolegal malpractice claims, counseling and informed consent should be performed when prescribing moderate-high dosages of corticosteroids. Further research is needed to characterize the long-term effects of corticosteroid usage in COVID-19 patients.

Fresh insights into glucocorticoid-induced diabetes mellitus and new therapeutic directions

Glucocorticoid hormones were discovered to have use as potent anti-inflammatory and immunosuppressive therapeutics in the 1940s and their continued use and development have successfully revolutionized the management of acute and chronic inflammatory diseases. However, long-term use of glucocorticoids is severely hampered by undesirable metabolic complications, including the development of type 2 diabetes mellitus. These effects occur due to glucocorticoid receptor activation within multiple tissues, which results in inter-organ crosstalk that increases hepatic glucose production and inhibits peripheral glucose uptake. Despite the high prevalence of glucocorticoid-induced hyperglycaemia associated with their routine clinical use, treatment protocols for optimal management of the metabolic adverse effects are lacking or underutilized. The type, dose and potency of the glucocorticoid administered dictates the choice of hypoglycaemic intervention (non-insulin or insulin therapy) that should be provided to patients. The longstanding quest to identify dissociated glucocorticoid receptor agonists to separate the hyperglycaemic complications of glucocorticoids from their therapeutically beneficial anti-inflammatory effects is ongoing, with selective glucocorticoid receptor modulators in clinical testing. Promising areas of preclinical research include new mechanisms to disrupt glucocorticoid signalling in a tissue-selective manner and the identification of novel targets that can selectively dissociate the effects of glucocorticoids. These research arms share the ultimate goal of achieving the anti-inflammatory actions of glucocorticoids without the metabolic consequences.

Asthma in Youth and Early-onset Type 2 Diabetes: A Nationwide Study of 1.72 Million Israeli Adolescents

BACKGROUND

The prevalence of both asthma and early-onset diabetes is on the rise; however, the association between them remains unclear. We examined a possible association of asthma at adolescence with type 2 diabetes in young adulthood.

METHODS

This is a nationwide, population-based study of 1 718 541 Israeli adolescents (57% males; mean age 17.3 years; range 16-19 years), examined before compulsory military service between 1992 and 2016, with data linked to the Israeli National Diabetes Registry. Asthma diagnosis and severity were determined by a board-certified pulmonologist and based on spirometry tests.

RESULTS

Type 2 diabetes developed in 58/9090 (0.64%), 507/97 059 (0.52%), 114/23 332 (0.49%), and 7095/1 589 060 (0.44%) persons with moderate-to-severe, mild, inactive, and no history of asthma, respectively, during a mean follow-up >13 years. The respective odds ratios (ORs) were 1.33 (95% CI, 1.02-1.74), 1.17 (1.06-1.28), and 1.09 (0.9-1.31), considering those without asthma history as the reference, in a model adjusted for birth year, sex, body mass index, and other sociodemographic variables. The association persisted when the analysis accounted for coexisting morbidities, and when persons without asthma, individually matched by age, sex, birth year, and body mass index were the reference. Both mild and moderate-to-severe asthma were associated with type 2 diabetes before age 35 years: ORs 1.18 (1.05-1.34) and 1.44 (1.05-2.00), respectively. The strength of the association was accentuated over time. The effect was unchanged when adjusted for oral and inhaled glucocorticoid use.

CONCLUSION

Adolescents with active asthma have higher risk to develop type 2 diabetes. This seems related to disease severity, independent of adolescent obesity status, apparent before age 35 years, and more pronounced in recent years.

Appraisal of Proactive Topical Therapy in Atopic Dermatitis: Pros and Cons

Atopic dermatitis is a common inflammatory skin disease that can affect both children and adults. It is a chronic disease with recurrent, highly pruritic eczematous lesions. Topical treatment with anti-inflammatory agents is the mainstay of treatment for atopic dermatitis, either in a reactive or proactive approach according to severity of the disease and always in combination with daily application of an emollient cream. Several studies have shown that proactive therapy with either topical corticosteroids or topical calcineurin inhibitors is significantly superior at reducing the number of flares and increasing the interval between flares compared with reactive therapy in patients with moderate and severe disease. The risk of side effects is considered low, and there seem to be no extra economic costs related to this treatment approach. Proactive therapy is an advisable treatment option for patients with moderate and severe atopic dermatitis to gain prolonged disease control; however, long-term safety data and data on when to stop do not yet exist.

Association of Potent and Very Potent Topical Corticosteroids and the Risk of Osteoporosis and Major Osteoporotic Fractures

Importance

Systemic and inhaled corticosteroids negatively affect bone remodeling and cause osteoporosis and bone fracture when given continuously or in high doses. However, risk of osteoporosis and major osteoporotic fracture (MOF) after application of topical corticosteroids (TCSs) is largely unexplored.

Objective

To examine the association between cumulative exposure to potent and very potent TCSs and risk of osteoporosis and MOF.

Design, Setting, and Participants

This nationwide retrospective cohort study included 723 251 Danish adults treated with potent or very potent TCSs from January 1, 2003, to December 31, 2017. Data were obtained from Danish nationwide registries. Filled prescription data were converted in equipotent doses to mometasone furoate (1 mg/g). Data were analyzed from June 1 to August 31, 2019.

Exposures

Patients were considered exposed when they had filled prescriptions of cumulative amounts corresponding to the equivalent of at least 500 g of mometasone, using filled prescriptions of 200 to 499 g as the reference group.

Main Outcomes and Measures

The co-primary outcomes were a diagnosis of osteoporosis or MOF. Hazard ratios (HRs) adjusted for age, sex, socioeconomic status, medication use, and comorbidity were calculated with 95% CIs using Cox proportional hazards regression models.

Results

A total of 723 251 adults treated with the equivalent of at least 200 g of mometasone were included in the analysis (52.8% women; mean [SD] age, 52.8 [19.2] years). Dose-response associations were found between increased use of potent or very potent TCSs and the risk of osteoporosis and MOF. For example, HRs of MOF were 1.01 (95% CI, 0.99-1.03) for exposure to 500 to 999 g, 1.05 (95% CI, 1.02-1.08) for exposure to 1000 to 1999 g, 1.10 (95% CI, 1.07-1.13) for exposure to 2000 to 9999 g, and 1.27 (95% CI, 1.19-1.35) for exposure to at least 10 000 g. A 3% relative risk increase of osteoporosis and MOF was observed per doubling of the cumulative TCS dose (HR, 1.03 [95% CI, 1.02-1.04] for both). The overall population-attributable risk was 4.3% (95% CI, 2.7%-5.8%) for osteoporosis and 2.7% (95% CI, 1.7%-3.8%) for MOF. The lowest exposure needed for 1 additional patient to be harmed (454 person-years) was observed for MOF with exposure of at least 10 000 g.

Conclusions and Relevance

These findings demonstrate that use of high cumulative amounts of potent or very potent TCSs was associated with an increased risk of osteoporosis and MOF.

A Practical Guide for the Management of Steroid Induced Hyperglycaemia in the Hospital

Glucocorticoids represent frequently recommended and often indispensable immunosuppressant and anti-inflammatory agents prescribed in various medical conditions. Despite their proven efficacy, glucocorticoids bear a wide variety of side effects among which steroid induced hyperglycaemia (SIHG) is among the most important ones. SIHG, potentially causes new-onset hyperglycaemia or exacerbation of glucose control in patients with previously known diabetes. Retrospective data showed that similar to general hyperglycaemia in diabetes, SIHG in the hospital and in outpatient settings detrimentally impacts patient outcomes, including mortality. However, recommendations for treatment targets and guidelines for in-hospital as well as outpatient therapeutic management are lacking, partially due to missing evidence from clinical studies. Still, SIHG caused by various types of glucocorticoids is a common challenge in daily routine and clinical guidance is needed. In this review, we aimed to summarize clinical evidence of SIHG in inpatient care impacting clinical outcome, establishment of diagnosis, diagnostic procedures and therapeutic recommendations.

Drugs Affecting Body Weight, Body Fat Distribution, and Metabolic Function-Mechanisms and Possible Therapeutic or Preventive Measures: an Update

PURPOSE OF REVIEW

Weight gain and body fat redistribution are common side effects of many widely used drugs. We summarize recent literature on prevalence data and mechanisms associated with drug-induced body fat changes and mechanisms to prevent or treat metabolic side effects.

RECENT FINDINGS

The highest prevalence of metabolic complications is seen with antipsychotics and antiretroviral drugs used in the treatment of HIV and may, at least partly, be responsible for the increased risk for co-morbid diseases such as diabetes, steatosis of the liver, and cardiovascular disease. The pathogenetic mechanisms leading to weight gain from antipsychotics are increasingly known and help to unravel the complex interaction that exists between psychopathology and metabolic complications. Although the classic lipodystrophy mainly occurred with older HIV drugs, also with the newer HIV treatment, weight gain seems to be a major side effect. Early detection of the metabolic consequences of drugs can lead to an early diagnosis of the complications and their treatment. Different medications, including the newer antidiabetics, are being studied in the therapy of drug-induced obesity. Future research should focus on identifying individuals at risk for metabolic side effects and on early markers to identify individuals with side effects so that timely treatment of metabolic complications can be initiated.

Joint AAD-NPF Guidelines of care for the management and treatment of psoriasis with topical therapy and alternative medicine modalities for psoriasis severity measures

Psoriasis is a chronic, inflammatory, multisystem disease that affects up to 3.2% of the United States population. This guideline addresses important clinical questions that arise in psoriasis management and care and provides recommendations based on the available evidence. The treatment of psoriasis with topical agents and with alternative medicine will be reviewed, emphasizing treatment recommendations and the role of dermatologists in monitoring and educating patients regarding benefits as well as risks that may be associated. This guideline will also address the severity assessment methods of psoriasis in adults.

Treatment of adult atopic dermatitis patients according to disease characteristics and demographics

Little is currently known about possible associations between disease specific characteristics of atopic dermatitis (AD) and use of medical treatments. We explored the use of AD treatments within the past 12 months in Danish adults according to distinct patient characteristics. Patients who had received a diagnosis of AD in a hospital in- or outpatient setting as adults were surveyed and data cross-linked to a national prescription registry. AD severity was measured by the Patient-Oriented SCORing Atopic Dermatitis (PO-SCORAD). A total of 3834 patients participated. Use of topical medication in the past 12 months increased with increasing AD severity, whereas no difference was observed for systemic medication use. Positive associations between AD in the face and neck, and use of mild and moderately potent topical corticosteroids were observed, while involvement of palms and chest was associated with use of more potent topical corticosteroids. The mean DLQI, skin pain, and itch severity scores were lower in patients managed only with topical corticosteroids (5.5, 3.2, and 4.3, respectively) compared to patients treated with both oral and topical medication (7.1, 3.8, and 5.0, respectively). Patients with frequent topical corticosteroid use tended to be older (50.7 vs 48.6 years), males (50.0% vs 33.6%), current daily smokers (17.3% vs 13.7%), and having asthma (59.1% vs 43.8%) compared with infrequent users of topical corticosteroids. We found a disconnect between the severity of AD signs and symptoms, and use of AD therapies. In particular, a very modest use of systemic immunosuppressants was seen even among patients with severe AD symptoms. However, the underlying clinical decisions and reasons behind this disconnect is not clear based on the current data.

Normal insulin sensitivity, glucose tolerance, gut incretin and pancreatic hormone responses in adults with atopic dermatitis

AIM

To examine whether adults with mild to moderate atopic dermatitis (AD) had reduced insulin sensitivity and/or exhibited other gluco-metabolic disturbances compared with carefully matched healthy controls.

MATERIALS AND METHODS

Sixteen adult, non-obese, non-diabetic patients with mild to moderate AD and 16 gender-, age- and body mass index (BMI)-matched healthy controls underwent a hyperinsulinaemic euglycaemic clamp (insulin infusion rate: 40 mU/m² /minute) and an oral glucose tolerance test (OGTT) with frequent blood sampling for gut and pancreatic hormones.

RESULTS

The two groups were similar in age (33 ± 3 vs. 33 ± 3 years, mean ± standard error of the mean [SEM]), gender (56% women), BMI (24.5 ± 0.7 vs. 24.4 ± 0.7 kg/m² ), physical activity level, fasting plasma glucose and HbA1c. Patients with AD had a mean Eczema Area and Severity Index score of 8.5 ± 1.0 (moderate disease) and a mean AD duration of 28 ± 3 years. During the OGTT, circulating glucose, insulin, C-peptide, glucagon and glucose-dependent insulinotropic polypeptide, respectively, were similar in the two groups, except glucagon-like peptide-1, which was higher in patients with AD. The clamp showed no differences in insulin sensitivity between groups (M-value 9.2 ± 0.6 vs. 9.8 ± 0.8, P = .541, 95% CI -1.51; 2.60), or circulating insulin, C-peptide and glucagon levels.

CONCLUSIONS

Using OGTT and the hyperinsulinaemic euglycaemic clamp technique, we found no difference in insulin sensitivity or other gluco-metabolic characteristics between patients with mild to moderate AD and matched healthy controls, suggesting that the inflammatory skin disease AD has little or no influence on glucose metabolism.

Crisaborole Ointment, 2%, for Treatment of Patients with Mild-to-Moderate Atopic Dermatitis: Systematic Literature Review and Network Meta-Analysis

Introduction

There is a need to compare efficacy and safety profiles of crisaborole ointment, 2%, versus other topical treatments across randomized clinical trials (RCTs). We performed this review/network meta-analysis to evaluate the comparative efficacy and safety of crisaborole versus other topical pharmacologic therapies for mild-to-moderate atopic dermatitis (AD) among patients aged ≥ 2 years.

Methods

Searches were conducted in MEDLINE, Embase, the Cochrane Collection Central Register of Clinical Trials, and the Database of Abstracts of Reviews of Effects using Ovid to identify English language articles reporting RCTs of topical anti-inflammatory agents in patients aged ≥ 2 years with mild-to-moderate AD published between inception and 10 March 2020. This review used a prespecified protocol with eligibility criteria for population, interventions, comparisons, outcomes, and study design. Efficacy was evaluated using the Investigator’s Static Global Assessment (ISGA) of clear (0) or almost clear (1) and expressed by hazard ratios (HR) with 95% credible intervals.

Results

Patients treated with crisaborole or tacrolimus ointment, 0.1% or 0.03%, versus vehicle alone were significantly more likely to achieve ISGA 0/1 at 28–42 days, with the greatest point estimate observed for the crisaborole comparison (hazard ratio: 2.07; 95% credible interval 1.76 to − 2.36; probability HR above 1 [p better]: 100.0%). Patients were also more likely to achieve ISGA 0/1 with crisaborole than with pimecrolimus cream, 1% (HR: 1.62; 95% credible interval 1.04–2.48; p better: 98.3%). While network meta-analysis for safety was not feasible because of data limitations, crisaborole pivotal studies (AD-301/AD-302) showed crisaborole was well tolerated.

Conclusions

Crisaborole was shown to be superior to vehicle and pimecrolimus and comparable to tacrolimus, 0.1% or 0.03%, with respect to ISGA 0/1 at 28–42 days in patients aged ≥ 2 years with mild-to-moderate AD. This evaluation of comparative efficacy of crisaborole further supports use of crisaborole as an effective therapeutic option in this population.

Allergen Immunotherapy and Atopic Dermatitis: the Good, the Bad, and the Unknown

PURPOSE OF REVIEW

In light of the recent advancements in atopic dermatitis treatment, this review aims to summarize the utility and efficacy of allergy immunotherapy in atopic dermatitis patients. We examine its mechanism, pathophysiology, cost-efficacy, and current guidelines for clinical practice.

RECENT FINDINGS

The literature supports the use of allergy immunotherapy in atopic conditions such as allergic rhinitis and asthma but insufficient evidence exists to suggest its efficacy in atopic dermatitis. The use of allergy immunotherapy has been shown to provide long-term cost savings in both the USA and the European Union in certain populations but differences in prescribing patterns and manufacturing make it difficult to study its impact on a larger, generalizable scale. Conflicting meta-analyses data and conclusions highlight the need for better, higher quality research to better understand allergy immunotherapy utility in atopic dermatitis.
