Abstract
BACKGROUND Daily diaries are an important modality for patient-reported outcome assessment. They typically comprise multiple questions, so understanding their underlying structure is key to appropriate analysis and interpretation. Structural evaluation of such measures poses challenges due to the high volume of repeated measurements. Potential strategies include selecting a single day, averaging item-level observations over time, or using all data while accounting for its multilevel structure. METHOD The above strategies were evaluated in a simulated dataset via exploratory and confirmatory factor modelling by comparing their impact on various estimates (i.e., inter-item correlations, factor loadings, model fit). Each strategy was additionally explored using real-world data from an observational study (the Asthma Nighttime Symptoms Diary). RESULTS Both single day and item average strategies resulted in biased factor loadings. The former displayed lower overall bias (single day: 0.064; item average: 0.121) and mean square error (single day: 0.007; item average: 0.016) but greater frequency of incorrect factor number identification compared with the latter (single day: 46.4%; item average: 0%). Increased estimated inter-item correlations were apparent in the item-average method. Non-trivial between- and within-person variance highlighted the utility of a multilevel approach. However, convergence issues and Heywood cases were more common under the multilevel approach (90.2% and 100.0%, respectively). CONCLUSIONS Our findings suggest that a multilevel approach can enhance our insight when evaluating the structural properties of daily diary data; however, implementation challenges still remain. Our work offers guidance on the impact of data handling decisions in diary assessment.

Abstract
To obtain current epidemiological information on primary focal hyperhidrosis in Japan, a large epidemiological survey was conducted using a web-based questionnaire. The prevalence of primary focal hyperhidrosis was 10.0% and the site-specific prevalence was highest for primary axillary hyperhidrosis (5.9%). The proportion of respondents with primary focal hyperhidrosis who had consulted a physician was 4.6%, which was similar to the low prevalence reported previously in 2013 in Japan. A questionnaire survey for physicians and individuals with primary axillary hyperhidrosis on the current medical management of primary axillary hyperhidrosis showed that physicians recognized the existence of patients who were very worried about hyperhidrosis, but failed to provide active treatment. Regarding the information provided by patients to physicians at presentation, it was found that patients failed to provide sufficient information to the physicians about their worries in daily life. Among individuals who had sought medical care with primary axillary hyperhidrosis, 62.3% reported that they were not currently receiving treatment, highlighting a challenge to be addressed regarding continued treatment. Frequently chosen options leading to willingness to receive treatment were less expensive treatment and highly effective treatment as well as feeling free to consult a physician, suggesting a desire for an improved medical environment.

Association of primary focal hyperhidrosis with anxiety induced by sweating: A cross-sectional study of Japanese university students focusing on the severity of hyperhidrosis and site of sweating. J Dermatol 2023; 50:364-374. [PMID: 36282908 DOI: 10.1111/1346-8138.16617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 10/04/2022] [Accepted: 10/09/2022] [Indexed: 12/01/2022]
Abstract
Hyperhidrosis significantly reduces patients' quality of life, with many reporting feeling highly anxious. However, the relationship between hyperhidrosis and anxiety induced by sweating has not been examined in detail. The current study examined the relationship between: (1) the presence of hyperhidrosis symptoms, (2) hyperhidrosis severity, and (3) the sites of the most sweating and anxiety induced by sweating. A cross-sectional web-based survey was conducted among university students, and 1080 consenting participants (600 males and 480 females; mean age, 18.8 years) were included in the analysis. The survey items were: (1) diagnostic criteria for hyperhidrosis, (2) Hyperhidrosis Disease Severity Scale, (3) presence of anxiety induced by sweating, and (4) site of the most sweating. The results of multiple logistic regression analysis adjusted for sex and age showed that the odds ratio (OR) for anxiety induced by sweating was significantly higher in participants who screened positive for hyperhidrosis than in those who screened negative (OR, 9.72 [95% CI, 5.80-16.27]). The OR of anxiety induced by sweating was 7.11 (95% CI, 3.99-12.65) for mild/moderate hyperhidrosis and 23.46 (95% CI, 7.15-76.93) for severe hyperhidrosis, compared with those who screened negative for hyperhidrosis. Compared with those who screened negative for hyperhidrosis, the OR for anxiety induced by sweating in those with the palmar, plantar, axillary, and head/face as the site of the most sweating was 7.74 (95% CI, 3.91-15.33), 14.86 (95% CI, 1.83-120.58), 16.92 (95% CI, 5.95-48.14), and 5.38 (95% CI, 1.39-20.74), respectively. Our findings suggest that participants who screened positive for hyperhidrosis, mild/moderate or severe, are at a higher risk of anxiety induced by sweating than participants who screened negative for hyperhidrosis.

J Dermatol 2021; 49:86-94. [PMID: 34636057 PMCID: PMC9293301 DOI: 10.1111/1346-8138.16188] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 08/19/2021] [Accepted: 09/25/2021] [Indexed: 11/24/2022]
Abstract
Glycopyrronium tosylate cloth, an anticholinergic drug, has been approved for the topical treatment of primary axillary hyperhidrosis in the USA, but its effects in Japanese patients have not been previously investigated. This 4-week, randomized, double-blind, vehicle-controlled, multicenter study was conducted to evaluate the efficacy and safety of glycopyrronium tosylate cloth for primary axillary hyperhidrosis patients in Japan. Eligible patients, who were ≥9 years of age and had primary axillary hyperhidrosis ≥6 months, with gravimetrically-measured sweat production ≥50 mg/5 min, and Hyperhidrosis Disease Severity Scale ≥3 (moderate) were randomized 1:1:1 to once daily topical glycopyrronium tosylate 3.75%, 2.5%, or vehicle. Overall, 497 patients (163 in the glycopyrronium tosylate 3.75% group, 168 in the glycopyrronium tosylate 2.5% group, and 166 in the vehicle group, hereinafter in this order) were randomized. Statistically higher proportions of patients in the glycopyrronium tosylate groups achieved ≥2-point improvement in Hyperhidrosis Disease Severity Scale and ≥50% reduction in sweat production from baseline versus vehicle at week 4 (51.6%, 41.1%, and 16.4%, respectively; p < 0.001 in both cases). Higher responder rates in the glycopyrronium tosylate groups compared with the vehicle group occurred as early as week 1. The most common treatment-emergent adverse events in patients treated with glycopyrronium tosylate were photophobia, mydriasis, thirst, and dysuria. Most treatment-emergent adverse events were mild as determined by the investigators. The incidence of treatment-emergent adverse events leading to treatment modification was low in the three groups. The 4-week use of topical glycopyrronium tosylate improved the patient-reported outcome measure Hyperhidrosis Disease Severity Scale and objectively-evaluated sweat production with a favorable benefit/risk profile.

Abstract
BACKGROUND Effective topical treatment options for patients with primary axillary hyperhidrosis (PAHH) are limited. A phase I trial showed promising results regarding the efficacy and safety of a topical cream containing glycopyrronium bromide (GPB). OBJECTIVES To assess the efficacy, safety and tolerability of a 4-week topical treatment of GPB 1% cream in patients with PAHH vs. placebo. METHODS In total, 171 patients (84 receiving placebo; 87 receiving GPB 1%) with PAHH were included in the 4-week, multicentre, randomized, double-blind, placebo-controlled phase IIIa part of the pivotal study. Sweat production was measured by gravimetry. Patients rated the impact of disease with the Hyperhidrosis Disease Severity Scale (HDSS) and Hyperhidrosis Quality of Life Index (HidroQoL© ). RESULTS Absolute change in sweat production from baseline to day 29 in logarithmic values was significantly larger in the GPB 1% group compared with the placebo group (P = 0·004). The improvement in HidroQoL exceeded the minimal clinically important difference of 4. The proportion of responders was twofold higher for sweat reduction (-197·08 mg GPB 1% vs. -83·49 mg placebo), HDSS (23% GPB 1% vs. 12% placebo) and HidroQoL (60% GPB 1% vs. 26% placebo). Treatment was safe: most treatment-emergent adverse effects were mild or moderate, and transient. Local tolerability was very good, with 9% of patients having only mild or moderate application-site reactions. The most reported adverse drug reaction was dry mouth (16%), an expected anticholinergic effect of the treatment. CONCLUSIONS GPB 1% cream may provide an effective new treatment option exhibiting a good safety profile for patients with PAHH. The long-term open-label part (phase IIIb) is ongoing.

Abstract
PURPOSE To critically appraise, compare and summarize the quality of all existing PROMs that have been validated in hyperhidrosis to at least some extend by applying the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. Thereby, we aim to give a recommendation for the use of PROMs in future clinical trials in hyperhidrosis. METHODS We considered studies evaluating, describing or comparing measurement properties of PROMs as eligible. A systematic literature search in three big databases (MEDLINE, EMBASE and Web of Science) was performed. We assessed the methodological quality of each included study using the COSMIN Risk of Bias checklist. Furthermore, we applied predefined quality criteria for good measurement properties and finally, graded the quality of the evidence. RESULTS Twenty-four articles reporting on 13 patient-reported outcome measures were included. Three instruments can be further recommended for use. They showed evidence for sufficient content validity and moderate- to high-quality evidence for sufficient internal consistency. The methodological assessment showed existing evidence gaps for eight other PROMs, which therefore require further validation studies to make an adequate decision on their recommendation. The Hyperhidrosis Disease Severity Measure-Axillary (HDSM-Ax) and the short-form health survey with 36 items (SF-36) were the only questionnaires not recommended for use in patients with hyperhidrosis due to moderate- to high-quality evidence for insufficient measurement properties. CONCLUSION Three PROMs, the Hyperhidrosis Quality of Life Index (HidroQoL), the Hyperhidrosis Questionnaire (HQ) and the Sweating Cognitions Inventory (SCI), can be recommended for use in future clinical trials in hyperhidrosis. Results obtained with these three instruments can be seen as trustworthy. Nevertheless, further validation of all three PROMs is desirable. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42020170247.

How to diagnose and measure primary hyperhidrosis: a systematic review of the literature. Clin Auton Res 2021; 31:511-528.

Abstract
PURPOSE Hyperhidrosis (i.e. excessive sweating) is diagnosed from patient medical history and physical examination. In addition, focal sweat measurements can substantiate the hyperhidrosis diagnosis. Likewise, the impact of living with hyperhidrosis can be assessed with patient-reported outcome measures. However, no consensus exists on how to diagnose hyperhidrosis, how to quantify the disease, or how to measure the impact hyperhidrosis has on patients. Therefore, the objective of this review was to summarize the literature on diagnostic criteria, focal sweat measurement methods, and patient-reported outcome measures of hyperhidrosis. METHODS A literature search of Cochrane Library, Embase, and PubMed was conducted. Studies that included and aimed at developing or validating hyperhidrosis diagnostic criteria, focal sweat measurement methods, or patient-reported outcome measures for individuals with hyperhidrosis were eligible for inclusion. The methodological quality of diagnostic accuracy studies about focal sweat measurement methods was determined using the Quality Assessment of Diagnostic Accuracy Studies-2. RESULTS Overall, 33 studies were included. We identified two sets of hyperhidrosis diagnostic criteria, one scale for assessment of severity of hyperhidrosis sweating, four focal sweat measurement methods, and 15 patient-reported outcome measures. CONCLUSION The algorithm for diagnosing hyperhidrosis and focal sweat measurement methods needs validation in large cohorts. Most patient-reported outcome measures for hyperhidrosis are not adequately validated. A potential solution is to develop a core outcome set that can standardize outcomes reported in clinical trials.

Abstract
BACKGROUND Glycopyrronium tosylate (GT; Qbrexza® [glycopyrronium] cloth, 2.4%) is a topical anticholinergic approved (USA) for primary axillary hyperhidrosis in patients aged ≥ 9 years. OBJECTIVE The objective of this study was to compare the pharmacokinetics and safety of GT to oral glycopyrrolate (phase I study) and assess the relationship between glycopyrronium pharmacokinetics and anticholinergic-related adverse events or efficacy with population pharmacokinetics using data from two phase II studies. METHODS In the phase I study, study staff applied GT to axillae of patients with primary axillary hyperhidrosis (aged 9-65 years) once daily (5 days); oral glycopyrrolate was administered to healthy adults (aged 18-65 years) every 8 hours (15 days). In the phase II studies (NCT02016885 [20 December, 2013], NCT02129660 [2 May, 2014]), adults with primary axillary hyperhidrosis applied topical glycopyrronium (0.8-3.2%) or vehicle to axillae once daily (4 weeks). Pharmacokinetic and adverse event data were collected in all studies. RESULTS Glycopyrronium pharmacokinetic parameters were similar between adult and pediatric patients treated with GT; there was no evidence of accumulation. Systemic absorption of glycopyrronium was lower with GT vs oral glycopyrrolate. No anticholinergic-related adverse events occurred with GT in the phase I study, while dry mouth and nasal dryness occurred with oral glycopyrrolate; anticholinergic adverse events occurred in the phase II studies. In the population pharmacokinetic analysis, frequency/severity of anticholinergic-related adverse events increased with higher glycopyrronium concentration; no relationship was observed between efficacy and pharmacokinetic measures. CONCLUSIONS These studies indicate limited absorption of GT compared to oral glycopyrrolate and a low risk of anticholinergic adverse events with proper GT administration when following instructions for use (wipe each underarm once with same cloth, wash hands, avoid ocular contact).

Abstract
BACKGROUND The Hyperhidrosis Quality of Life Index (HidroQoL©) is a validated patient-reported outcome measure capturing the quality of life of people affected by hyperhidrosis. OBJECTIVES We aimed to extend the validity evidence to physician-confirmed diagnosis of primary axillary hyperhidrosis. METHODS Data from a phase III randomized placebo-controlled clinical trial were used (n = 171). Confirmatory factor analysis was carried out to confirm the a priori two-factor structure of the HidroQoL. Internal consistency was assessed using Cronbach's α. Intraclass correlation coefficients (ICCs) were calculated to evaluate test-retest reliability after days -7 to -4. Convergent validity was assessed using correlations with the Dermatology Life Quality Index (DLQI), the Hyperhidrosis Disease Severity Scale (HDSS) and gravimetric sweat production. Known groups were analysed to evaluate discriminative validity. Responsiveness after 29 days was assessed and minimal important difference (MID) values were calculated using both anchor- and distribution-based approaches. All analyses were carried out for total HidroQoL and its two domains. RESULTS The two-factor structure of the HidroQoL was confirmed. Internal consistency and test-retest reliability were strong (Cronbach's α 0·81-0·90; ICCs 0·89-0·93). Correlations with other outcome measures were in line with a priori hypotheses. The HidroQoL discriminated between different severity groups (P ≤ 0·001) and showed sensitivity to change towards improvement (P < 0·001). An MID value of 4 is proposed for the total scale. CONCLUSIONS This study supports excellent measurement properties including clinical applicability of the HidroQoL in primary axillary hyperhidrosis and suggests a MID of 4 be applied to clinical trial data.

Abstract
BACKGROUND/OBJECTIVES Glycopyrronium tosylate (GT) cloth, 2.4% is a topical anticholinergic approved in the United States for primary axillary hyperhidrosis in patients ≥9 years. This post hoc analysis evaluated long-term response (efficacy and safety) in pediatric patients (≥9 to ≤16 years) to GT in the 44-week, open-label extension (NCT02553798) of two, phase 3, double-blind, vehicle-controlled, 4-week trials (NCT02530281, NCT02530294). METHODS In the double-blind trials, patients ≥9 years with primary axillary hyperhidrosis were randomized 2:1 to once-daily GT:vehicle. Those who completed the study could receive open-label GT for up to an additional 44 weeks. Safety assessments included treatment-emergent adverse events (TEAEs) and local skin reactions (LSRs). Descriptive efficacy assessments included gravimetrically measured sweat production, Hyperhidrosis Disease Severity Scale response (≥2-grade improvement), and Children's Dermatology Life Quality Index. RESULTS Of 43 pediatric patients completing either double-blind trial, 38 (88.4%) entered the open-label extension (age, years: 9 [n = 1], 12 [n = 2], 13 [n = 7], 14 and 15 [n = 9 each], 16 [n = 10]). The safety profile observed was similar to the double-blind trials. Most TEAEs (>95%) were mild/moderate, related to anticholinergic activity, and infrequently led to discontinuation (n = 1/38 [2.6%]). No pediatric patients experienced a serious TEAE. Most anticholinergic TEAEs did not require a dose modification and resolved within 7 days. Approximately, one-third of patients (n = 13/38 [34.2%]) had LSRs; most were mild/moderate in severity. Improvements in efficacy measures were maintained from the double-blind trials. CONCLUSIONS Long-term, once-daily GT for up to 48 weeks (4-week double-blind plus 44 week open label) provides a noninvasive, well-tolerated treatment option for pediatric patients with primary axillary hyperhidrosis.

Abstract
Glycopyrronium tosylate (Qbrexza™) is available as single-use, pre-moistened cloths and has been approved in the USA for the topical treatment of primary axillary hyperhidrosis in adults and children ≥ 9 years of age. Glycopyrronium tosylate is effective in reducing patient-reported severity of disease and gravimetrically measured sweat production in this patient population; improvements have been shown to be maintained throughout long-term treatment (up to 48 weeks). Glycopyrronium tosylate is generally well tolerated, with most adverse events being mild to moderate in severity. Glycopyrronium tosylate thus provides a self-administered, non-invasive alternative to topical antiperspirant therapy and clinic-based treatments in adults with primary axillary hyperhidrosis, and is the only alternative to topical antiperspirants specifically approved in children and adolescents ≥ 9 years of age.

Abstract
BACKGROUND Glycopyrronium tosylate (GT) is a topical anticholinergic approved in the USA for primary axillary hyperhidrosis in patients aged ≥ 9 years. GT was evaluated for primary axillary hyperhidrosis in replicate, randomized, double-blind, vehicle-controlled, phase III trials. GT reduced sweating severity and production versus vehicle and was generally well tolerated. OBJECTIVE Our objective was to evaluate patient-reported outcomes (PROs) from these trials. METHODS Patients aged ≥ 9 years with primary axillary hyperhidrosis ≥ 6 months, gravimetrically measured sweat production ≥ 50 mg/5 min in each axilla, Axillary Sweating Daily Diary (ASDD) Item 2 severity score ≥ 4, and Hyperhidrosis Disease Severity Scale (HDSS) score ≥ 3 were randomized 2:1 to GT 3.75% or vehicle applied once daily to each axilla for 4 weeks. The 4-item ASDD, 6 Weekly Impact (WI) items, Patient Global Impression of Change (PGIC), HDSS, and Dermatology Life Quality Index (DLQI) were utilized. RESULTS In the pooled population, 463 patients were randomized to GT and 234 to vehicle; 426 (92.0%) and 225 (96.2%) completed the trials. At baseline, most patients considered their axillary sweating to be at least moderate in severity, impact, and bothersomeness (ASDD items 2, 3, and 4, respectively). Improvement was substantially greater for GT than for vehicle at every study week, and, at week 4, ASDD scores improved from baseline by 62.6 versus 34.0% (severity), 65.5 versus 40.3% (impact), and 65.4 versus 39.0% (bothersomeness). Improvements favoring GT versus vehicle also occurred for WI items, PGIC, HDSS, and DLQI. CONCLUSIONS PRO results demonstrated that GT reduced the disease burden of primary axillary hyperhidrosis. TRIAL REGISTRATION Clinicaltrials.gov; ATMOS-1 (NCT02530281), ATMOS-2 (NCT02530294).
