The impact of hyperhidrosis on patients' daily life and quality of life: a qualitative investigation

What do Hyperhidrosis Quality of Life Index (HidroQoL©) scores mean? Transferring science into practice by establishing a score banding system

BACKGROUND

The Hyperhidrosis Quality of Life Index (HidroQoL©) is a measure of quality of life (QoL) impacts in hyperhidrosis (HH).

OBJECTIVES

We aimed to establish score banding systems for the HidroQoL total score for specific contexts representing different severity/impact categories by using the Dermatology Life Quality Index (DLQI) and the Hyperhidrosis Disease Severity Scale (HDSS) as anchors, including data from 357 patients from a phase III clinical trial.

METHODS

We used the HDSS, the established DLQI score bands and two single items (items 5 and 7) of the DLQI as anchors for the creation of banding systems for the HidroQoL. These anchors were chosen via consensus among an expert group according to relevance to patient experience. Due to the distribution of the HDSS and the single DLQI item 7, receiver operating characteristic curves were computed in order to create an optimal cut-off value of the HidroQoL total score. For the DLQI banding system and the single DLQI item 5, we created a banding system for the HidroQoL based on the distribution of their different categories.

RESULTS

A score of 30 and greater is proposed as the cut-off value for sweating that 'always interferes in daily activities', based on the HDSS as anchor. In terms of overall skin QoL effects, score bands of 0-6, 7-18, 19-25, 26-32 and 33-36 represent 'no effect', 'small effect', 'moderate effect', 'very large effect' and 'extremely large effect' on the patient's life, respectively.

CONCLUSIONS

In this study, we propose different banding systems for four different contexts: skin-specific QoL (DLQI banding), HH severity (HDSS), working and studying (single DLQI item 7) and social and leisure activities (single DLQI item 5). These banding systems and cut-off values can be used in clinical research and practice to place the patients in different severity categories.

Impostor phenomenon is a common feature among individuals with primary hyperhidrosis

Background

Primary hyperhidrosis consists of excessive focal sweating. Affected individuals camouflage the sweating on their body, avoiding stigmatisation. Hence, misrepresentation in social interactions is a common feature in patients with hyperhidrosis. The aim of this study was to investigate impostor phenomenon, perfectionism, self-compassion, stress and anxiety among individuals with primary hyperhidrosis.

Methods

A cross-sectional study was conducted at our clinic among 100 participants with axillary and palmar primary hyperhidrosis. The questionnaire contained a hyperhidrosis part and Perceived Stress Scale-4, Generalised Anxiety Disorder Scale-2, Clinical Perfectionism Questionnaire-6, Self-Compassion Scale Short form and Clance Impostor Phenomenon Scale. Descriptive statistics was used for analyses of categorical variables. As data were normally distributed independent t-test and one-way analysis of variance with post hoc Tukey test were used to compare the mean values for the questionnaires with other variables. Pearson's correlation was used, and a forward multiple linear regression model was performed to predict presence of impostor phenomenon with gender, age and other scales in this study.

Results

Impostor phenomenon occurred in almost half of our patients (48%) with hyperhidrosis. While feelings of impostor phenomenon were more common in women, there was no difference between gender regarding its intensity levels (p = 0.07). In addition, we found a significant (p < 0.001) negative correlation between impostor phenomenon and self-compassion, while feelings of impostoer phenomenon increased with stress, anxiety and perfectionism (p < 0.001).

Conclusions

Feelings of impostor phenomenon was found in 48% of individuals with hyperhidrosis which indicates that it is a common feature in this patient group. Future research is warranted regarding the prevalence of impostor phenomenon in hyperhidrosis and other medical conditions, among men and women, seeking medical healthcare. Psychological interventions in hyperhidrosis may be beneficial both for the individual and in public health, by facilitating management of patients' daily lives and saving considerable resources in healthcare regarding pharmacological interventions and medical consultations.

Longitudinal Assessment of Facial Hyperhidrosis Management: Evaluating the Utility and Quality of Life Improvements following Botulinum Toxin Injection

Facial hyperhidrosis is a debilitating condition that can severely impact the quality of life. This study aimed to assess the long-term utility of Botulinum toxin type A therapy (BTA) for facial hyperhidrosis and its impact on quality of life over a one-year period. Conducted at the Pius Brinzeu Clinical Emergency Hospital in Timisoara, Romania, this longitudinal observational study involved 77 adult patients with primary facial hyperhidrosis. Participants received two sessions of Botulinum toxin injections (50 U IncoBTX-A each) and were evaluated at baseline, 6 months, and 12 months using the Hyperhidrosis Disease Severity Scale (HDSS), WHOQOL-BREF, Dermatology Life Quality Index (DLQI), and a bespoke survey. The study demonstrated significant reductions in HDSS scores from 3.6 ± 0.5 to 1.2 ± 0.8 post-treatment, sustained at 1.3 ± 0.6 at 12 months (p-value < 0.001). DLQI scores markedly decreased from 24.8 ± 4.2 to 6.2 ± 2.1 post-treatment, stabilizing at 6.5 ± 2.5 at 12 months (p-value < 0.001). Sweat production significantly dropped from 0.75 g ± 0.15 to 0.18 g ± 0.07 per 15 min (p-value < 0.001). WHOQOL-BREF scores improved notably in the mental domain from 66.7 ± 6.1 to 70.8 ± 5.2 at 12 months (p-value < 0.001), with physical and social domains also showing significant improvements. Correlation analysis revealed strong negative correlations between DLQI total score and HDSS (rho = -0.72, p-value < 0.001) and sweat production (rho = -0.68, p-value < 0.001). Regression analysis indicated significant predictors for DLQI total score, including HDSS (B Coefficient = -3.8, p-value < 0.001) and sweat production (B Coefficient = -2.2, p-value < 0.001). BTA therapy significantly improved the quality of life in facial hyperhidrosis patients, with lasting effects on symptom severity, sweat production, and quality of life domains. The correlation and regression analyses further substantiated the treatment's impact on both physical and psychological aspects. These findings advocate Botulinum toxin as a viable long-term treatment for facial hyperhidrosis.

Videothoracoscopic surgery in children

Video-assisted thoracic surgery (VATS) is now being used with increasing frequency for a wide variety of indications in pediatric patients. Although there is no high level of evidence for the advantages of VATS in the pediatric patient group, the proven benefits of this method in the adult patient group have encouraged thoracic surgeons to perform VATS in this patient population. In this study, the procedures performed in pediatric patients under 18 years of age and their results were reviewed with the help of articles obtained as a result of searches using relevant keywords in the English literature (PubMed, Web of Science, EMBASE, and Cochrane). The frequency, indications, and results of the procedures performed differed according to age groups.

Reconstituted and frozen botulinum toxin A is as effective and safe as fresh for treating axillary hyperhidrosis: A retrospective study

The use of reconstituted and frozen left-over botulinum toxin A, for treatment of patients with axillary hyperhidrosis seems to be common practice in healthcare. Thus, the objective of this study was to investigate the efficacy and safety of frozen and thawed versus fresh reconstituted abobotulinum toxin (Dysport®) and onabotulinum toxin (Botox®) in the treatment of axillary hyperhidrosis. A retrospective study was conducted analysing efficacy and data from pre- and 24 weeks post-treatment questionnaires together with medical records of individuals with moderate to severe axillary hyperhidrosis. The patients had received fresh prepared botulinum toxin A in their right axilla while frozen and thawed botulinum toxin A had been administered in their left axilla. Treatment was conducted at our Hyperhidrosis Clinic, Umeå University Hospital, Sweden 2019-2021. Pre- and post-treatment questionnaires from 106 patients were analysed. The patients were 18 to 55 years old, with a mean age of 30.7 ± 9.9 years. No significant differences in patient-reported variables, Hyperhidrosis Disease Severity Scale and VAS 10-point scale, were found between the different preparations (frozen compared to fresh) for abobotulinum toxin and onabotulinum toxin, before treatment and at 6 months follow-up. Multivariable regression analysis resulted in no significant difference regarding side-effects between the preparations or brands of botulinum toxin. The findings of this study support our clinical experience that both abobotulinum toxin and onabotulinum toxin, reconstituted, frozen and thawed, seem to be as effective and safe as fresh prepared botulinum toxin when treating axillary hyperhidrosis. Our findings indicate that left-over preparations of abo- and onabotulinum toxins, stored and frozen for up to 6 months, is a cost-and time-effective way of handling botulinum toxin for treatment of axillary hyperhidrosis.

The Efficacy of Botulinum Toxin A in Treating Palmar Hyperhidrosis - a Literature Review

Background:Palmar hyperhidrosis, a condition characterized by excessive sweating in the palms, considerably impacts the quality of life (QoL). Although various treatment modalities are available, the efficacy and safety of Botulinum toxin type A (BTX-A) needed further investigation. Methods:We conducted a literature review, with open-label, controlled trial, double-blind placebo-controlled and observational designs being eligible for inclusion, according to the PRISMA guidelines. Results:All the six selected studies consistently reported the efficacy of BTX-A in reducing symptoms of hyperhidrosis, without significant side effects. Botulinum toxin type A treatment was found to improve the QoL significantly, to reduce sweat rate and production and to have no detrimental effect on grip strength. The duration of the antisudorific effect also indicated the potential for long-term management of palmar hyperhidrosis with BTX-A. Conclusions:Our findings corroborated the effectiveness and safety of BTX-A in managing palmar hyperhidrosis across diverse patient outcomes and experiences. Botulinum toxin type A emerged as a promising treatment modality for this condition, capable of improving the QoL, reducing symptoms and offering long-term relief without significant side effects.

Development and Validation of a Nomogram to Predict Recurrence of Primary Hyperhidrosis after CT-guided Percutaneous Radiofrequency Sympathectomy

PURPOSE

To evaluate the recurrence rate of primary hyperhidrosis (PH) after computed tomography (CT)-guided radiofrequency sympathectomy (RFS) and identify risk factors associated with recurrence.

MATERIALS AND METHODS

A total of 290 patients with PH who underwent CT-guided RFS were included in this retrospective cohort study. The electronic medical record was reviewed for patients' information and procedural parameters. Follow-ups were conducted for recurrence rate, and Hyperhidrosis Disease Severity Scale was used to assess presence or absence of recurrence. Stepwise regression and the least absolute shrinkage and selection operator regression algorithms were used for feature selection.

RESULTS

The recurrence rate 1 year after procedure was 17.6%. Male (hazard ratio [HR], 2.35; 95% confidence interval [CI], 1.08-5.15), low postoperative palm or foot temperature (HR, 0.77; 95% CI, 0.60-0.98), high postoperative heart rate (HR, 1.06; 95% CI, 1.02-1.10), low preoperative and postoperative hospital anxiety and depression score difference (HR, 0.59; 95% CI, 0.43-0.80), and the absence of compensatory hyperhidrosis immediately after procedure (HR, 0.46; 95% CI, 0.22-0.98) were established as independent factors affecting prognosis. A nomogram was built accordingly. The C indices of the training and testing sets were 0.773 and 0.659, respectively.

CONCLUSIONS

Follow-up results showed that the recurrence rate of PH treated with CT-guided RFS was low. This study constructed and validated a nomogram to predict the recurrence of PH 1 year after CT-guided RFS, which is convenient for interventionalists to evaluate accurately the prognosis of patients postoperatively and to identify high-risk patients who need more active treatment.

Long-term evaluation of the safety and efficacy of a novel 20% oxybutynin hydrochloride lotion for primary palmar hyperhidrosis: An open-label extension study

The long-term safety and efficacy of 52-week application of oxybutynin hydrochloride 20% lotion (20% OL) for the treatment of primary palmar hyperhidrosis (PPHH) in Japanese patients aged ≥12 years were evaluated in an open-label extension (OLE) of a 4-week, randomized, double-blind (DB) study. The OLE included 114 patients who completed the DB study and wished to continue treatment and 12 new patients. In the safety analysis population (125 patients), the incidence of adverse events (AEs) and adverse drug reactions (ADRs) was 79.2% and 36.0%, respectively. Serious AEs were observed in two patients but were considered unrelated to the investigational drug. The incidence of AEs that led to study discontinuation was 1.6%. The incidence of application site AEs and ADRs was 35.2% and 26.4%, respectively. The severity of most events was mild. The incidence of anticholinergic AEs related to dry mouth was 3.2% for thirst and 0.8% for dry throat. The long-term efficacy of 20% OL was confirmed by a long-lasting reduction in sweat volume and improvement in the Hyperhidrosis Disease Severity Scale and Dermatology Life Quality Index. This study has several limitations: First the results may include some bias because most of the participants were from the prior DB study; second, the results may not be generalizable because only a few participants were in the age group most susceptible to PPHH (i.e., < 15 years old); and third, the study did not obtain safety information from treatment for more than 52 weeks, so this information must be collected in clinical practice in the future. No reduced therapeutic effect was observed in patients with PPHH in this study after 52-week application of 20% OL. Also, few patients experienced serious AEs or AEs that led to study treatment discontinuation.

Patients' satisfaction after bilateral thoracoscopic sympathicolysis

Background

Palmar hyperhidrosis is a distressing condition implicating individuals' social life and self-esteem. Surgery has proven to be highly effective with excellent safety profile. However, compensatory hyperhidrosis (CH), a relatively common adverse event of the procedure, is sometimes problematic in a few patients.

Patients and Methods

A questionnaire, including Hyperhidrosis Disease Severity Scale (HDSS), was designed to assess the overall satisfaction of patients who underwent bilateral endoscopic thoracic sympathectomy between November 2018 and July 2021. They were requested to respond to the questionnaire before surgery and during the follow-up visits.

Results

Sixty-three patients were recruited, 37 males and 26 females. The age of the participants ranged from 6 to 27 years (mean 17.05 ± 5.55 years). Most patients reported a positive impact on their professional and social life. Two patients experienced significant compensatory hyperhydrosis impacting their daily life. There was a significant improvement of the HDSS score after surgery. Around 95.2% of the participants (n = 60) had three-point improvement indicating 80% reduction of sweat production.

Conclusion

: Bilateral endoscopic thoracoscopic sympathectomy has shown a high success rate with low adverse events. CH, however, remains a significant cause of morbidity in few patients. Therefore, continuous evaluation of patients' satisfaction is of utmost importance to help improve our understanding to risk factors and prevalence of CH, improve our techniques to minimise its occurrence and treat patients with distressing symptoms. These data will guide surgeons when counselling patients to make insightful decisions based on the benefits and risks of the procedure.

A novel lotion formulation of 20% oxybutynin hydrochloride for the treatment of primary palmar hyperhidrosis: A randomized, placebo-controlled, double-blind, phase III study

BACKGROUND

No previous controlled studies have been specifically designed or adequately powered to show the efficacy of topical oxybutynin for palmar hyperhidrosis by using quantitative measures.

OBJECTIVE

To evaluate efficacy of 20% oxybutynin hydrochloride lotion (20% OL) in reducing palmar sweat volume in patients with primary palmar hyperhidrosis (PPHH).

METHODS

In a randomized controlled trial, Japanese patients with PPHH aged 12 years and older received either 20% OL (n = 144) or placebo (n = 140) on both palms once daily for 4 weeks. Palmar sweat volume was measured by the ventilated capsule method. For the primary outcome, response was defined as a reduction of sweat volume of at least 50% from baseline.

RESULTS

At week 4, the responder rate for sweat volume was significantly higher in the 20% OL arm than in the placebo arm (52.8% vs 24.3%, respectively; treatment difference, 28.5% [95% CI, 17.7% to 39.3%]; P < .001). No serious adverse events occurred, and no adverse events led to treatment discontinuation.

LIMITATIONS

The treatment period was only 4 weeks.

CONCLUSIONS

In patients with PPHH, 20% OL is superior to placebo in reducing palmar sweat volume.

Questionnaire-based epidemiological survey of primary focal hyperhidrosis and survey on current medical management of primary axillary hyperhidrosis in Japan

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.

The Impact of Hyperhidrosis on Quality of Life: A Review of the Literature

Hyperhidrosis is a condition of excessive sweating, which can have profound physical and mental effects. Hyperhidrosis is a significantly impactful and distressing illness that warrants equal attention as other more well-known dermatologic conditions. However, because of a lack of awareness among the public, stigma, and difficulty with access to treatments (due to cost or insurance coverage), patients are less likely to be diagnosed and treated. In hyperhidrosis, quality-of-life surveys can be useful for determining the magnitude of symptoms and to evaluate treatment outcomes. The purpose of this study was to conduct a narrative literature review to investigate the impact of hyperhidrosis on quality of life. A total of 49 articles investigating the impact of primary hyperhidrosis on quality of life were selected for the review. Hyperhidrosis is a potentially debilitating illness that affects multiple domains of patients' lives including their psychological, physical, and social functioning. Despite the significant impacts, patients with hyperhidrosis are less likely to seek care. Here, we explore these impacts, and disparities in care, in more detail.

Percutaneous Radiofrequency Sympatholysis in the Treatment of Primary Palmar Hyperhidrosis: A Retrospective Case-Controlled Study of Rib-Based Anatomical Targeting

PURPOSE

To compare the efficacy, adverse reactions, quality of life, and patient satisfaction of percutaneous radiofrequency (RF) thoracic sympatholysis at different rib-based anatomic targets for primary palmar hyperhidrosis (PPHH).

MATERIALS AND METHODS

Patients with PPHH were divided according to the target, namely, the upper edge (Group U) and lateral border (Group L) of the fourth rib; there were 30 patients (mean age, 24.9 years; women, 31, 51.7%) and 60 cases in each group. The Hyperhidrosis Disease Severity Scale (HDSS) and Dermatology Life Quality Index (DLQI) were assessed.

RESULTS

From before RF sympatholysis to 12 months after, the proportion of patients with HDSS Grades III and IV (100%-26.7%) and the DLQI (19.78 ± 5.08 to 4.98 ± 4.18) decreased significantly (P < .001). At 3, 6, and 12 months after RF, the HDSS grades were better in Group L than in Group U (P = .005, .002, and .004). At 6 and 12 months after RF, the DLQI in Group L was lower than that in Group U (P = .012 and .016), and at 1, 6, and 12 months after RF, patient satisfaction was higher than that in Group U (P = .025, .014, and .009). Adverse events were mild; 8 patients (13.3%) demonstrated compensatory hyperhidrosis at 12 months after RF, and there was no difference between the 2 groups (P = .448); neuralgia and pneumothorax also did not differ (P = .522 and .643).

CONCLUSIONS

RF sympatholysis targeting the lateral border of the fourth rib had higher efficacy, better quality of life, and higher patient satisfaction.

Computed Tomography-Guided Percutaneous T4 Thoracic Sympathetic Radiofrequency Thermocoagulation for Primary Palmar Hyperhidrosis: A Retrospective Observational Trial

PURPOSE

To evaluate the efficacy, safety, and patient satisfaction of computed tomography (CT)-guided percutaneous T4 thoracic sympathetic radiofrequency thermocoagulation (RFT) for the treatment of primary palmar hyperhidrosis (PPHH).

MATERIALS AND METHODS

A total of 158 patients who underwent bilateral thoracic sympathetic RFT at the T4 level were analysed. Hyperhidrosis Severity Scale (HDSS), Dermatologic Quality of Life Index (DLQI), patient satisfaction, and adverse events were evaluated within 12 months after RFT.

RESULTS

The mean age of the patients was 25.27 years, and 95 (60.1%) were females. The technical success, defined as planned needle placement and completion of RFT, was 99.4%. After the procedure, 243 hands (77.4%) were completely dry; and 58 hands (18.4%) were partially dry. From before RFT to 12 months after RFT, the proportion of hands with the HDSS grades 3 and 4 from 100% decreased to 31.9%; and that with the DLQI scores D and E from 100% decreased to 4.0% (P < .001). The clinical success rate was 76.6%, and the patient satisfaction rate was 80.8% at 12 months after RFT. During the procedures, there was unilateral local bleeding in two patients (0.6%) and bradycardia in five patients (3.2%); after the procedures, unilateral pneumothorax occurred in 15 patients (4.7%) and closed thoracic drainage was performed in two patients (0.6%); thoracic neuralgia occurred in 24 patients (15.2%). The incidence of compensatory hyperhidrosis (CH) 12 months after RFT was 15.2%.

CONCLUSIONS

CT-guided percutaneous T4 thoracic sympathetic RFT is safe, effective, and minimally invasive for the treatment of PPHH.

LEVEL OF EVIDENCE

Level 2 observational study with dramatic effect.

Transfersomal eosin topical delivery assisted by fractional CO2 laser for photodynamic treatment of palmar hyperhidrosis: case study

Hyperhidrosis is a condition in which the cholinergic receptors on the eccrine glands are overstimulated, resulting in excessive sweating. It is considered a serious cosmetic and psychological problem that affects the patient's quality of life. Searching for novel treatment modalities is required to minimize the side effects and to attain better patient satisfaction.Photodynamic therapy (PDT), using eosin as a photosensitizer, is developed as a promising modality of the treatment of palmar and axillary hyperhidrosis. In this study, we treated six cases suffering palmar hyperhidrosis by applying the fractional CO₂ laser prior to PDT session. For PDT, a hydrogel of eosin loaded in a transfersomes as a nano-delivery carrier was applied for 5 min, followed by irradiation by intense pulsed light (IPL). The prepared transfersomes loaded by eosin were spherical in shape with encapsulation efficiency of 33 ± 3.5%, particle size 305.5 ± 5.7 nm, average zeta potential of - 54 ± 7.6 mV with 80 ± 4% of the loaded eosin was released after 3 h. Two cases achieved 90% improvement after four sessions, three patients needed six sessions to show 75% improvement, while one patient showed only 25% improvement after six sessions. This resulted in shortening the time of PS application and decreasing the number of sessions required to achieve acceptable improvement. More clinical studies on large number of patients are required to optimize the results.

Uses of eye drops in dermatology, literature review

Background: Since medication absorption through the skin and eye tissue seems similar, commercially available eye-drops could be used to treat skin diseases when topical therapies are unavailable or unaffordable. The FDA-approved and off-label applications of various eye drops used as topical treatments in dermatological clinical practice were highlighted in this review.Methodology: A thorough PubMed and Google Scholar library search using various combinations of the keywords (Eye drop, ocular solution, conjunctival installation, and skin diseases, topical, local, beta-blockers, prostaglandin, cyclosporin, apraclonidine, atropine, oxymetazoline).Results and conclusions: Based on the findings of the studies reviewed, timolol is highly recommended for infantile hemangioma and other vascular skin conditions such as angiomas, Kaposi sarcoma, acne, rosacea, and wound healing. Bimatoprost is a drug that can be used to treat hypotrichosis of any kind, as well as mild localized alopecia areata and leukoderma. Oxymetazoline ispromising for treating facial erythema. We recommend apraclonidine for mild upper eyelid ptosis induced botulinum neurotoxin. We don't recommend atropine for hyperhidrosis, although it can help with hydrocystomas and pruritis produced by syringomas. Tobramycin will need to be tested in RCTs before it can be confirmed as a viable alternative to systemic treatments for treating green nail syndrome.

Microneedling Delivery of Botulinum Toxin Versus Intradermal Injection in the Treatment of Facial Hyperhidrosis

BACKGROUND

The current treatments of Facial hyperhidrosis (FH) are often limited and are associated with many adverse effects.

OBJECTIVE

The objective was to study the efficacy and safety of botulinum toxin-A delivery by microneedling versus its intradermal injection in the treatment of FH. Forty-two patients with FH were subjected to microneedling (Mn) followed by topical application of BTX-A on one side of the face and intra-dermal injection of BTX-A on the other side. Two sessions were performed at two week intervals. The assessment tools were Hyperhidrosis Disease Severity Scale (HDSS), the Dermatology Life Quality Index (DLQI), and patient satisfaction.

RESULTS

A score of one of HDSS was achieved in 85.7 percent of patients on the intradermally injected side versus 83.3 percent on the microneedling side (P=0.76%). Most of the patients on the injection side responded with the first session while the microneedling side responded with the second one (P<0.001). The DLQI was highly significant on both sides post-treatment (P<0.001). The side effects were mild in the form of pain on the intradermally injected sides, and mild transient erythema on the microneedling side. The microneedling side showed higher patient satisfaction compared to the intradermally injected side.

CONCLUSION

Both techniques were safe and effective in controlling the FH. Microneedling delivery of BTX-A was less painful and had higher patient satisfaction.

THE PHARMACOLOGICAL TREATMENT AND MANAGEMENT OF HYPERHIDROSIS

INTRODUCTION

Idiopathichyperhidrosis is a dysfunctional disorder involving eccrine sweat glands and its impact on patients' daily quality of life is well-known. Unlike some years ago, when only poor effective and safe therapeutic alternatives were available, nowadays, several emerging pharmacological active substances have gained significant space as treatment options.

AREAS COVERED

The authors report on, in this narrative review, the emerging data from the literature focusing on the pharmacological treatments to draw up a drug treatments flow-chart for patients with idiopathic hyperhidrosis, taking into consideration specific differences among axillary, palmoplantar and craniofacial hyperhidrosis.

EXPERT OPINION

Idiopathic hyperhidrosis, regardless of the site of involvement, remains a functional disorder that places a significant burden on patients. After balancing efficacy against adverse events, systemic therapy, although off-label for all forms of hyperhidrosis can represent an additive therapeutic option for patients with insufficient response to topical treatment according to a step wise therapeutic approach. Until the pathophysiological mechanisms underlying hyperhidrosis are clear, and the etiological therapeutic approach become realistic, the greatest challenge in the therapeutic management of hyperhidrotic patients seems to be the search for the most convenient combination between different therapeutic modalities (topical and systemic agents, and botulinum toxins) to achieve long-term control of the disease symptoms.

Hyperhidrosis Comorbidities and Treatments: A Register-based Study among 511 Subjects

Hyperhidrosis is a dermatological condition that causes psychosocial impairment and has a negative impact on patients’ quality of life. The epidemiology of hyperhidrosis is currently poorly understood. The aim of this study was to analyse comorbidities and treatments in 511 subjects with hyperhidrosis selected from the patient records of Oulu University Hospital. The mean age of patients with local hyperhidrosis was 27.9 years and the majority were female (62.7%). The most common anatomical site of symptoms in the youngest age group was the palms, whereas the axillae were a more common site in advanced age. Depression was a common comorbidity in both local (11.6%) and generalized hyperhidrosis (28.6%). Anxiety affected 12.7% of patients with generalized hyperhidrosis. In 36.8% of the patients with local hyperhidrosis there was a delay in diagnosis of more than 10 years. The most commonly used treatments included topical antiperspirants, iontophoresis and botulin toxin injections.

Effectiveness of unilateral sequential video-assisted sympathetic chain blockage for primary palmar hyperidrosis in children and adolescents

INTRODUCTION

Primary palmar hyperhidrosis (PPH) is a severely debilitating condition that can affect patients of any age. Thoracoscopic sympathectomy provides a definitive treatment for PPH. Aim of this study is to investigate the effectiveness of unilateral sequential video-assisted thoracic sympathetic chain clamping (VATSCC) by clips application in pediatric population.

METHODS

The surgical procedure was done in the semi-sitting position, under general anesthesia with orotracheal intubation. Mean operation time was 23 ± 6 min (range 12-45). Two 5 mm ports were inserted at the level of the middle axillary line in the second and fourth intercostal space respectively. The sympathetic chain was identified, and two clips were applied, the first one at the level of the third and the second one, at the level of the fourth rib. No chest tube was used. Resolution of symptoms, complications, recurrence rate, onset and duration of compensatory hyperhidrosis were analyzed.

RESULTS

From August 2017 to September 2021, 58 patients (male:female ratio 32:26), mean age 16.5 years (range 14-19), with PPH underwent unilateral sequential VATSCC by clips application, starting on the dominant hand. The contralateral side was operated 2 months after. All patients except one (transient pneumothorax) were discharged on the first post-op day. No immediate or late complications have been recorded. Mean follow-up was 32 months (range 6-41). All patients except one (1,7%), affected by Raynaud's disease, showed a complete resolution of the symptom. Seven patients (12%) developed transient moderate compensative hyperhidrosis (CH) that spontaneously disappeared in the postoperative period.

CONCLUSIONS

Unilateral sequential thoracoscopic sympathetic chain clamping for PPH in pediatric patients is a safe and very effective procedure with a low complication rate and low incidence of postoperative CH that, in our experience, resolved spontaneously in the postoperative period, after the second surgery leading to an improvement in the quality of life.

Navigating in the fog. Facing delays, rejection and ignorance when seeking help for primary hyperhidrosis

Primary hyperhidrosis (PH) is a disease characterized by focal and excessive sweating.Purpose: The aim of this study was to describe the experiences of men and women with PH when seeking help for their condition.Method: A qualitative interview study with 30 men and women diagnosed with PH was conducted. Data was inductively analysed using manifest and latent content analysis.Results: The analysis resulted in a theme: Navigating in the fog, based on the categories doubtful encounters with health care professionals, helpful encounters with health care professionals, delays due to inadequate knowledge, and supported urge for help.Conclusions: Deficient knowledge and understanding about PH create a sense of resignation in individuals, resulting in delay of seeking treatment. Support from others, life-changing events, and finding information about PH were important motivating factors in seeking help and demanding access to treatment. A holistic approach towards patients with PH is important to reduce stigma and acknowledge the problems that are encountered in their daily lives. Educating health care professionals and students so that patients can be identified and assessed without delay and making information available about PH in schools and pharmacies could improve the general knowledge and facilitate obtaining treatment for individuals with PH.

Topical glycopyrronium tosylate in Japanese patients with primary axillary hyperhidrosis: A randomized, double-blind, vehicle-controlled study

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.

Selective T3-T4 sympathicotomy versus gray ramicotomy on outcome and quality of life in hyperhidrosis patients: a randomized clinical trial

Compensatory hyperhidrosis is the leading cause of patients' dissatisfaction after thoracic sympathicotomy. The study aimed to reduce compensatory hyperhidrosis to increase patients’ satisfaction. A prospective randomized study on palmar hyperhidrosis, May 2016–September 2019. Twenty-one patients T₃–T₄ sympathicotomy and 21 T₃–T₄ gray ramicotomy. Data prospectively collected. Analysis at study's end. Focus on the sweating, temperature, quality of life baseline and postoperatively, compensatory hyperhidrosis, hand dryness, patients' satisfaction, and if they would undergo the procedure again and recommend it. No baseline differences between groups. Hyperhidrosis was controlled postoperatively in all patients. No mortality, serious complications, or recurrences. Sympathicotomy worse postoperative quality of life (49.05 (SD: 15.66, IR: 35.50–63.00) versus ramicotomy 24.30 (SD: 6.02, IR: 19.75–27.25). After ramicotomy, some residual sweating on the face, hands, and axillae. Compensatory sweating worse with sympathicotomy. Satisfaction higher with ramicotomy. Better results with ramicotomy than sympathicotomy regarding hand dryness, how many times a day the patients had to shower or change clothes, intention to undergo the procedure again or recommend it to somebody else, and how bothersome compensatory hyperhidrosis was. T₃–T₄ gray ramicotomy had better results than T₃–T₄ sympathicotomy, with less compensatory sweating and higher patients' satisfaction.

Botulinum Toxin Versus Placebo: A Meta-Analysis of Treatment and Quality-of-life Outcomes for Hyperhidrosis

AIMS

This study aims at assessing the treatment effect, disease severity and quality-of-life outcomes of botulinum toxin (BTX) injections for focal hyperhidrosis.

METHODS

We included randomized controlled trials of BTX injections compared with placebo for patients with primary or secondary focal hyperhidrosis. PubMed, Embase and the Cochrane Library were searched to August 2020. Gravimetric sweat rate reduction, disease severity measured by Hyperhidrosis Disease Severity Scale and quality-of-life assessment measured by Dermatology Life Quality Index were the outcomes of interest. Cochrane risk-of-bias tools were employed for quality assessment of given randomized controlled trials.

RESULTS

Eight studies met our inclusion criteria (n=937). Overall, risk bias was mixed and mostly moderate. BTX injections showed reduced risk in comparison with placebo for the gravimetric quantitative sweat reduction of > 50 % from baseline (risk difference: 0.63, 95% CI 0.51 to 0.74). Additionally, improvements were seen for disease severity and quality-of-life assessments evaluated by Hyperhidrosis Disease Severity Score reduction of ≥ 2 points (risk difference: 0.56, 95% CI 0.42 to 0.69) and mean change in Dermatology Life Quality Index (mean difference: - 5.55, 95% CI - 7.11 to - 3.98). The acquired data were insufficient to assess for long-term outcomes and limited to an eight-week follow-up period.

CONCLUSIONS

In focal axillary hyperhidrosis, BTX significantly reduces sweat production and yields superior outcomes in assessments of disease severity and quality-of-life. However, the quality-of-evidence is overall moderate and included studies account for short-term trial periods only. Further studies assessing BTX in comparison with first-line treatments for hyperhidrosis are warranted.

A glycopyrronium bromide 1% cream for topical treatment of primary axillary hyperhidrosis: efficacy and safety results from a phase IIIa randomized controlled trial

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.

Measurement properties of patient-reported outcome measures (PROMs) in hyperhidrosis: a systematic review

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.

'Excessive sweating is not a feminine thing': A qualitative study of women's experiences suffering from primary hyperhidrosis

BACKGROUND

Primary hyperhidrosis, excessive focal sweating is a common disease equally affecting men and women. Women tend to seek care more often and assess being more affected by hyperhidrosis in their daily life. The aim of this study was to explore experiences of living with primary hyperhidros in a sample of 15 women.

METHODS

Individual, semi-structured interviews with a purposive sample of 15 women diagnosed with primary hyperhidrosis and analysed by qualitative content analysis utilising an inductive approach.

RESULTS

The analysis resulted in a theme, constantly guarding the female image, based on three categories, misfitting the feminine norms, avoiding the attention of others and passing like any woman. Primary hyperhidrosis in women disrupted the ideal feminine appearance. Wearing clothes that concealed hyperhidrosis and distancing from social gatherings, in combination with negative remarks by others, created stress and anxiety and had a negative effect on self-esteem. Women felt poorly understood by others regarding the extent of their sweating and were misunderstood in intimate situations while trying to reduce the sweat production. Choices regarding education and career opportunities were affected, since being exposed and receiving attention due to primary hyperhidrosis was unwanted. Treatment with botulinum toxin liberated women from excessive sweating and removed a social handicap they described living with.

CONCLUSION

Primary hyperhidrosis in women disrupts the feminine appearance, lowers self-esteem and hinders social interactions. Clinicians assessing primary hyperhidrosis need to be aware that women may report the impairments from primary hyperhidrosis as being more associated with body image and appearance than with functional reductions in daily life. Educating patients, providing accurate information regarding the disease via media and cooperating with patient groups are important for increasing awareness and achieving progress in care for women with primary hyperhidrosis.

Measurement properties of patient-reported outcome measures (PROMs) in patients with hyperhidrosis: protocol for a systematic review

BACKGROUND

Hyperhidrosis is a chronic skin condition that impairs the patient's quality of life (QoL). There are several patient-reported outcome measures (PROMs) for patients affected by hyperhidrosis available; however an evidence-based assessment of their quality has not been undertaken so far.

OBJECTIVE

In our systematic review, we aim to identify all existing PROMs that were developed and/or validated for measuring patient-reported outcomes in patients with hyperhidrosis and assess their measurement properties in a transparent and structured way to give a recommendation for future clinical research.

METHODS/DESIGN

Our systematic review aims to contain all PROMs developed and/or validated for patients with hyperhidrosis. We will perform a highly sensitive, systematic literature search including the databases MEDLINE (Ovid), EMBASE (Ovid), and Science Citation Index Expanded and Social Sciences Citation Index (Web of Science). Especially studies which evaluate, describe, or compare measurement properties of PROMs for patients with hyperhidrosis will be considered as eligible. Two independent reviewers will judge the eligibility of the studies found in the literature search. The study and PROM characteristics will be summarized in evidence tables. The methodological quality of each study will be assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. We will apply predefined and consensus-based quality criteria for good measurement properties. Subsequently, the quality of the evidence will be graded. Furthermore, aspects on interpretability and feasibility will be described. A final recommendation will be given.

DISCUSSION

In our systematic review, we aim to provide a comprehensive description of the quality of all existing PROMs for patients with hyperhidrosis. The assessment of measurement properties, interpretability, and feasibility will serve as a guidance regarding the selection of PROMs for future clinical hyperhidrosis trials.

Evaluation of the serum magnesium and vitamin D levels and the risk of anxiety in primary hyperhidrosis

BACKGROUND

Excessive sweating is considered primary hyperhidrosis if it is triggered by emotional states without any thermogenic or other underlying disease from the eccrine glands. This may be due to dysfunction in the autonomic nervous system.

AIMS

To investigate the relationship between Vitamin D and Mg deficiency and the risk of anxiety and depression in patients with primary hyperhidrosis.

PATIENTS/METHODS

This cross-sectional, case-control study was conducted between July and October 2019. 49 primary hyperhidrosis patients in Group I and 47 age and gender matched healthy individuals in Group II were included in the study.

RESULTS

The mean 25 (OH) D and Mg levels in Group I were statistically significantly lower than in Group II (p < 0.001 and p = 0.002, respectively). Statistically significant differences were found between the groups in terms of anxiety and depression (p < 0.001 and p = 0.033, respectively). There was no significant relationship between the HADS-A / HADS-D scores and the severity of primary hyperhidrosis (r = -0.131, p = 0.096; correlation coefficient = 0.232, p = 0.447). However, a significant correlation was observed between HADS-A scores and serum Mg levels (r = -0.439, p = 0.007).

CONCLUSION

Anxiety and depression are common in patients with primary hyperhidrosis. As shown in this study, both anxiety and depression can be seen with low Mg levels in patients with primary hyperhidrosis. This could possibly be related to the pathological mechanism involving Vitamin D and Mg, which determines the common pathway affecting primary hyperhidrosis and anxiety/depression.

Limited Systemic Exposure with Topical Glycopyrronium Tosylate in Primary Axillary Hyperhidrosis

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).

Cost-effectiveness of topical glycopyrronium tosylate for the treatment of primary axillary hyperhidrosis

AIMS

Primary axillary hyperhidrosis (PAHH) is a condition characterized by excessive sweating that negatively impacts health-related quality of life, with significant psychological and social impacts. Glycopyrronium tosylate (GT) is a topical anticholinergic approved in the United States for treatment of PAHH in patients 9 years of age and older. Our objective was to assess the cost-effectiveness of GT as first-line topical therapy compared to topical aluminum chloride from a United States commercial perspective.

MATERIALS AND METHODS

A Markov model was developed consisting of four health states based on the Hyperhidrosis Disease Severity Scale (HDSS) over a time horizon of 5 years with discount rates of 3% for both costs and outcomes. Transitions between health states were driven by HDSS response, defined as an improvement of ≥2 points. Non-responders and those who discontinue could switch to later line treatments or no treatment. Health utility scores were based on HDSS scores, supported by published literature.

RESULTS

Over 5 years, GT yielded 0.12 greater QALYs and 0.93 greater LYs with response compared to treatment with prescription aluminum chloride at an incremental cost of $10,584. Relative to prescription aluminum chloride, GT resulted in an incremental cost-effectiveness ratio (ICER) of $87,238 per QALY gained, $11,349 per LY with response. The ICER fell below $100,000 for 66% of probabilistic sensitivity analysis simulations and below $150,000 for 82% of simulations.

LIMITATIONS

This analysis represents a simplified scenario of a hypothetical PAHH patient. Due to sparse data, assumptions were required for treatment patterns, efficacy, and persistence.

CONCLUSION

Based on the analysis of incremental cost per QALY gained, GT may be cost-effective relative to prescription aluminum chloride at commonly accepted willingness to pay thresholds.

A systematic evidence-based review of treatments for primary hyperhidrosis

Objective

Hyperhidrosis (excessive sweating) is associated with significant quality-of-life burden yet is often undertreated. With limited FDA-approved treatments, health care providers must determine optimal treatment among approved and off-label options. Key objectives of this review were to reassess, update, and expand a previous systematic review of commonly used treatment options for primary hyperhidrosis, including consideration of aluminum and zirconium compounds.

Methods

We performed a qualitative systematic review of efficacy, health-related quality of life, satisfaction, and safety of interventions, replicating and expanding the strategy outlined in a previous systematic review, with the addition of studies utilizing a within-patient design. We performed a critical appraisal of identified studies to determine risk of bias (RoB) and strength of evidence (SOE).

Results

A total of 32 studies were eligible for critical appraisal. Only three studies - two clinical trials of glycopyrronium cloth (2.4%) and one trial of botulinum toxin A injections in axillary hyperhidrosis were rated as "low" RoB; both had SOE ratings of "moderate" for use in axillary hyperhidrosis - the highest rating included in this review.

Conclusions

Optimal treatment choice depends on several factors, including understanding the quality of evidence regarding each treatment's efficacy and safety (considerations of convenience and cost are beyond the scope of this review). In hyperhidrosis, as in other clinical conditions, treatment decisions should be patient centered. At this time, because of the quality of evidence, only imprecise estimates of effect are possible for hyperhidrosis treatments included in this review, and statements about comparative effectiveness are not possible.

Efficacy of photodynamic therapy for treatment of primary palmar hyperhidrosis

Palmar hyperhidrosis represents a condition with a significant cosmetic and psychological burden. Various treatment modalities are available; however, searching for newer options to meet patients' needs and expectations is encouraged. The study aimed to evaluate the efficacy of photodynamic therapy (PDT) for treatment of primary palmar hyperhidrosis. Two different photosensitizers for PDT were evaluated: eosin Y, and methylene blue. The study focused on the clinical efficacy, patient's satisfaction, and the time and number of sessions needed to achieve a satisfactory response. Twenty patients with primary palmar hyperhidrosis were enrolled in a single-center clinical study. Patients were treated with PDT for a maximum of eight sessions. Two photosensitizers were tested: eosin Y, and methylene blue for the right and left hand, respectively. The Hyperhidrosis disease severity scale (HDSS), and Sweating Intensity Visual Scale of Minor's test were used for assessment. Photodynamic therapy effectively reduced the severity scores of hyperhidrosis with comparable results between the two photosensitizers. The treatment effect was maintained up to 3 months after the last procedure. Photodynamic therapy is a good treatment option for primary palmar hyperhidrosis with results maintainable for 3 months after the treatment end.

The Meaning of Living for Men Suffering From Primary Hyperhidrosis

Primary hyperhidrosis means excessive focal sweating and it has a negative effect on the mental health of those affected. Although there is no gender difference regarding the prevalence of the disease, men are less likely to seek help for this condition. The aim of this study was to explore the meaning of living with primary hyperhidrosis in men. Interviews with 15 men, selected by purposive sampling, were performed at Umeå University Hospital in Sweden between June 2016 and October 2017, and analyzed using qualitative content analysis technique according to Graneheim and Lundman (2004). This study found one theme, namely, to be captured in a filthy body, based on the categories: surrender to the condition reluctantly; prepare for a sweat attack; withdraw from close contacts; and worry about others' perceptions. The theme describes men living with hyperhidrosis feeling filthy while they struggle to control or hide the excessive sweating. Insufficient understanding from others and being reminded from the sweating is stressful and results in a sense of captivity. Interpreting the result, we conclude that the disease could stigmatize the individual, which has a negative effect on mental health and the will to seek help. Meanwhile, providing information about the disease early, as in schools, could increase the willingness of men to seek medical help. The results of this study also reinforce quantitative studies reporting the negative effects of primary hyperhidrosis on mental health.

Treatment Patterns, Depression, and Anxiety Among US Patients Diagnosed with Hyperhidrosis: A Retrospective Cohort Study

Introduction

Hyperhidrosis is associated with social and emotional stress due to limitations on health-related quality of life. This study examined real-world treatment patterns and concomitant depression and/or anxiety in patients with hyperhidrosis.

Methods

Commercial health plan members in the US with ≥ 2 hyperhidrosis diagnosis codes and/or antiperspirant prescription claims were identified from January 2010 through November 2017. A control cohort (CC) of patients without hyperhidrosis was matched to the hyperhidrosis cohort on demographic characteristics. Depression and/or anxiety were identified by ≥ 1 relevant diagnosis code or pharmacy claim. A multivariable logistic regression model estimated odds of treatment in the hyperhidrosis cohort, and depression/anxiety in the hyperhidrosis cohort and CC, adjusting for patient characteristics.

Results

A total of 44,484 patients with hyperhidrosis were identified, of whom 58.5% were female, with a mean (± standard deviation) age of 36.5 ± 16.5 years (83.5% ≥ 18 years). A small majority of patients (51.6%, 0.69/person-year) received treatment with prescription antiperspirants. Post-index oral systemic therapies, medical procedures, and surgical options were uncommon. At 12 months post-index, 48.4% of the sample had not filled a prescription for extra- or prescription-strength antiperspirants. Compared with the CC (n = 137,451), a higher percentage of patients with hyperhidrosis had depression or anxiety reported during follow-up (41.1 vs. 28.2%, p < 0.001); this corresponded to higher adjusted odds of depression/anxiety in patients with hyperhidrosis [odds ratio (OR) 1.76, 95% confidence interval (CI) 1.72–1.80, p < 0.001]. Baseline depression and/or anxiety were associated with lower odds of receiving hyperhidrosis treatment (OR 0.77, 95% CI 0.73–0.80), as was increasing age and male gender. Patients with hyperhidrosis also had more frequent incident depression/anxiety during follow-up (18.2 vs. 10.6%, p < 0.001).

Conclusion

In this real-world analysis, hyperhidrosis was associated with increased odds of depression and/or anxiety. However, relatively low percentages of patients received prescription topical or oral treatments or underwent surgery, suggesting that tolerability, efficacy, and provider awareness may be limiting factors in the effective treatment of hyperhidrosis.

The impact of adolescents' everyday life experiences on their primary hyperhidrosis treatment - a qualitative study

INTRODUCTION

Hyperhidrosis is a disease affecting around 5% of the western population. The qualitative field within hyperhidrosis among adolescents has been sparsely investigated. The aim of this study was to investigate the impact of adolescent hyperhidrosis patients' everyday life experiences on their hyperhidrosis treatment.

METHODS

Qualitative, semi-structured interviews were carried out. In total, 10 adolescents, aged 12-18 years, participated in the study. Data were analyzed using a set of inseparable activities as described by Van Manen.

RESULTS

Three main themes were identified to represent common shared experiences across participants. The first theme was related to the impact of hyperhidrosis on the physical and psychological dimensions of life as it negatively affected both physical abilities and one's self-concept. Having hyperhidrosis was experienced as living a life in secrecy, characterized by individual routines for concealment and isolation in order to protect social identity.

CONCLUSION

The large negative impact of hyperhidrosis on adolescents is a strong justification for treatment of the disease. The substantial emotional distress suggests that treatment may need to include psychological support.

Hyperhidrosis Quality of Life Index (HidroQoL©): further validation and clinical application in patients with axillary hyperhidrosis using data from a phase III randomized controlled trial

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.

Quality of life after thoracic sympathectomy for palmar hyperhidrosis: a meta-analysis

OBJECTIVE

Palmar hyperhidrosis affects 0.6-10% of the general population, having an important impact in patients' quality of life. The definitive treatment for palmar hyperhidrosis is thoracic sympathectomy. The purpose of this study is to evaluate the quality of life after thoracic sympathectomy for palmar hyperhidrosis.

METHODS

The interest studies were searched in six comprehensive databases. The quality of the studies was assessed using the risk of bias tool recommended by the Cochrane system evaluation manual. Meta-analysis was performed with RevMan version 5.3. The outcome of interest was quality of life. The subgroup analysis and sensitive analysis were performed.

RESULTS

Nine trials, including 895 patients, with accessible data comparing preoperative quality of life score with postoperative quality-of-life score were used for data analysis. Compared with preoperative quality-of-life score, application of thoracic sympathectomy improved the postoperative quality of life of palmar hyperhidrosis patients (MD = 57.81, 95% CI 53.33-62.30). Subgroup analysis of the different thoracic sympathectomy segment showed that there was no significant difference in the results obtained when operated with single segment or multiple segments (single segment: MD = 61.16, 95% CI [56.10, 66.22], multiple segments: MD = 52.14, 95% CI [48.39, 55.88]).

CONCLUSION

The meta-analysis provided evidence of the improved quality of life after thoracic sympathectomy for palmar hyperhidrosis.

Correlation between benign joint hypermobility syndrome and primary focal hyperhidrosis in children: a novel concept

Background

Benign joint hypermobility syndrome (BJHS) is one of the most common hereditary connective tissue disorders in children in which autonomic nervous system involvement has been reported. This study aimed to evaluate the frequency of primary focal hyperhidrosis in children with BJHS.

Methods

This observational-analytical study was conducted in a case-control setting on children aged 3 to 15 years in 2018 at Mofid Children’s Hospital, Tehran, Iran. Benign joint hypermobility syndrome was diagnosed according to the Brighton criteria; then, the patients referred to a dermatologist for evaluation of hyperhidrosis.

Results

In total, 130 eligible patients with confirmed BJHS and 160 age- and sex-matched healthy subjects were enrolled in this study. Primary focal hyperhidrosis (PFH) was seen in 56.2 and 16.3% of the cases and controls, respectively, indicating a significant difference (P < 0.05). The severity of hyperhidrosis did not differ between the two groups.

Conclusion

Although the results of the study showed a significant correlation between BJHS and PFH, more comprehensive studies are needed to confirm these findings.

Topical Glycopyrronium Tosylate in Primary Axillary Hyperhidrosis: A Profile of Its Use

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.

Impact of Video-Assisted Thoracoscopic Sympathectomy and Related Complications on Quality of Life According to the Level of Sympathectomy

BACKGROUND

Primary hyperhidrosis is defined as excessive sweating of idiopathic etiology, associated with sympathetic hyperactivity, which greatly impacts patients' quality of life (QoL). The definitive treatment for palmar and axillary hyperhidrosis (PAH) is video-assisted thoracic sympathectomy (VATS). The objective of this study was to evaluate the quality of life of patients with PAH before and after VATS according to the level of sympathectomy performed, as well as the presence of compensatory hyperhidrosis (CH) and other complications.

METHODS

All patients who underwent VATS in our vascular surgery department between January 2011 and December 2016 were included in the analysis. From 120 contact attempts, 88 interviews were carried out. Patients were divided into 2 groups according to the intervened thoracic level: high thoracic ganglion (HTG; T2, T2-T3, T2-T3-T4; n = 68) and low thoracic ganglion (LTG; T3, T3-T4, T4; n = 20). The questionnaire evaluated preoperative PAH severity, the presence of CH, preoperative and postoperative QoL, and postoperative satisfaction.

RESULTS

The median age of patients was 29 years, and the median follow-up period was 32 months (IQR of 34 months). Most patients had severe or very severe PAH (97.7%) and preoperative QoL was bad or very bad (95.5%). Postoperatively, QoL was significantly improved in all domains evaluated, with no differences observed between the groups. The overall percentage of complications was 11.4%, mostly pneumothorax, but there was a significantly lower incidence of complications in the HTG group (P = 0.029). Compensatory hyperhidrosis developed in 85.2% of cases, but it was only considered intolerable in 10.2%. The incidence of CH was 82.4% in the HTG group and 95% in the LTG group, with no statistically significant differences between the groups (P = 0.147).

CONCLUSIONS

Palmar and axillary hyperhidrosis severely affects QoL, and video-assisted thoracic sympathectomy was proven to be effective regardless of the target ganglion resected. Although CH was frequent, it was tolerated in most cases.

Management Strategies Of Palmar Hyperhidrosis: Challenges And Solutions

Palmar hyperhidrosis is a potentially disabling condition for which management remains a therapeutic challenge. Given the significant impact on quality of life, various treatment options are available, ranging from topical agents and medical devices to systemic therapies and surgical interventions. Nonsurgical approaches, i.e. topical antiperspirants, botulinum toxin injections, iontophoresis, and systemic agents, are all supported by the current literature. Patients with mild-to-moderate disease can often benefit from topical therapies only. As disease severity progresses, systemic oral medication, such as anticholinergic drugs, usually becomes necessary. Last-line surgical approaches (sympathetic denervation) should be reserved for severe refractory cases. Recently, therapeutic strategies have been evolving with several new agents emerging as promising alternatives in clinical trials. In practice, however, each modality comes with its own benefits and risks. An individual therapeutic ladder is generally recommended, taking into account disease severity, benefit-to-risk profile, treatment cost, patient preference, and clinician expertise. This review will provide an update on current and emerging concepts of management for excessive hand sweating to help clinicians optimize therapeutic decision-making.
