J Dermatolog Treat. 2021 Jun 21:1-25. doi: 10.1080/09546634.2021.1944971. Online ahead of print.

ABSTRACT

Background A few studies have described an increased prevalence of skin infections in individuals with hyperhidrosis compared to others. However, it remains uncertain whether hyperhidrosis is an independent risk factor for skin infections.Objective To compare the risk of skin infections in individuals with and without hyperhidrosis.Methods In this retrospective cohort study, data on hyperhidrosis were collected from the Danish Blood Donor Study. Blood donors included in 2010-2019 were followed from inclusion until December 2019. Data on redeemed prescriptions against skin infections were collected from the National Prescription Register. The intensity of prescription-use by hyperhidrosis status was assessed in Andersen-Gill models.Results Overall, 4,176 (9.6%) of 43,477 blood donors had self-reported hyperhidrosis and 437 (0.34%) of 127,823 blood donors had hospital diagnosed hyperhidrosis. Self-reported hyperhidrosis was associated with the use of antibiotic prescriptions (adjusted hazard ratio =1.21; 95% confidence interval 1.00-1.45, p = 0.047). Hospital diagnosed hyperhidrosis was associated with the use of antibiotic (adjusted hazard ratio =1.33; 95% confidence interval 1.03-1.68, p = 0.028) and topical antifungal prescriptions (adjusted hazard ratio =1.43; 95% confidence interval 1.04-1.97, p = 0.027).Conclusions Hyperhidrosis is associated with the use of prescriptions for antibiotics and topical antifungals. This suggests a clinically relevant association between hyperhidrosis and skin infections.

Progress and lack of progress in hyperhidrosis research 2015-2020. A concise systematic review

Int J Dermatol. 2021 May 26. doi: 10.1111/ijd.15654. Online ahead of print.

ABSTRACT

Hyperhidrosis is excessive sweating that is uncontrollable and occurring regardless of temperature. Quality of life is significantly impaired, and psychiatric comorbidity is common. The objective of the study is to undertake a systematic review of research in the last 5 years regarding hyperhidrosis. Five databases were searched from July 2015 to July 2020 for all research on hyperhidrosis. High-quality research articles were sought for progress in diagnosis, etiology and epidemiology, and use of patient reported outcomes (PROs) as well as randomized clinical trials (RCTs) on any treatment intervention. Outcomes of interest were disease severity, sweat rate, quality of life, patient satisfaction, and adverse events. Trial quality was assessed by the Cochrane risk-of-bias tool. A narrative synthesis was presented. Twenty-nine papers were included in the review: 13 investigational articles, 10 RCTs, three cohort studies, and three reviews. The studies varied in terms of quality, population, intervention, and methods of outcome assessment. The majority were very small studies, and most RCTs were at high risk of bias. Few studies on diagnosis, epidemiology, and etiology were of sufficient quality to be presented. The interventions discussed were iontophoresis, botulinum toxin, anticholinergic medication, curettage, and energy-based technologies. Progress in the diagnostics and etiology of hyperhidrosis is limited with the same being true for treatment. In a 5-year-old systematic review, it was concluded that there was moderate-quality evidence to support the use of botulinum toxin for axillary hyperhidrosis. It was advocated to conduct a trial comparing BTX and iontophoresis for palmar hyperhidrosis. Unfortunately, this has not yet been performed. Hyperhidrosis is still as underserved and under-studied as before.

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

Syst Rev. 2021 Jun 2;10(1):163. doi: 10.1186/s13643-021-01701-w.

ABSTRACT

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.

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

Int J Qual Stud Health Well-being. 2021 Dec;16(1):1930642. doi: 10.1080/17482631.2021.1930642.

ABSTRACT

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.

A phase III, 52-week, open-label study to evaluate the safety and efficacy of 5% sofpironium bromide (BBI-4000) gel in Japanese patients with primary axillary hyperhidrosis

J Dermatol. 2021 May 26. doi: 10.1111/1346-8138.15927. Online ahead of print.

ABSTRACT

A long-term study was conducted in Japanese patients with primary axillary hyperhidrosis who completed the preceding 6-week phase III, confirmatory study of 5% sofpironium bromide gel (hereinafter referred to as sofpironium) to evaluate the safety and efficacy of 52-week treatment with sofpironium. In the long-term study, 185 patients who completed the confirmatory study (94 and 91 patients in the vehicle and sofpironium groups, respectively) started to receive sofpironium (switching and extension groups, respectively), and all these patients were included in both the full analysis set (FAS) and the safety analysis set (SAF). In the FAS, there were more females than males (73.0% vs. 27.0%), and median age was 38.0 years. A total of 161 patients (86 and 75 patients in the switching and extension groups, respectively) completed the study at week 52. The proportions of patients with hyperhidrosis disease severity score of 1 or 2 and a 50% or more reduction in total gravimetric weight of sweat were 57.4% in the switching group and 58.2% in the extension group at week 52. The proportions of patients who achieved this efficacy end-point in the long-term study were similar to that (53.9%) in the sofpironium group in the confirmatory study. In the SAF, the incidences of adverse events (AEs) were 80.9% in the switching group and 83.5% in the extension group, and the incidences of adverse drug reactions were 39.4% and 45.1%, respectively. AEs that occurred in at least 20% of patients in both treatment groups were application site dermatitis (25.5% and 33.0%, respectively) and nasopharyngitis (31.9% and 23.1%, respectively). Reported AEs were generally mild, and there were no deaths. Serious AEs occurred in three patients, but none were considered related to the study drug. In this study, the efficacy of sofpironium was maintained during 52-week treatment, and no new safety risk was observed.

Pathological Changes in Axillary Hyperhidrosis and Axillary Osmidrosis Induced by Microwave Treatment: Comparison of Single- and Double-Pass Irradiation

Lasers Surg Med. 2021 May 26. doi: 10.1002/lsm.23412. Online ahead of print.

ABSTRACT

BACKGROUND AND OBJECTIVES: To analyze histopathological changes and degree of damage to the axillary tissue due to single- and double-pass irradiation therapy using a microwave energy-based device. STUDY DESIGN/MATERIALS AND METHODS: We included 15 axillary hyperhidrosis and axillary osmidrosis patients who received microwave irradiation therapy between March 2017 and March 2019. Ten patients underwent single-pass irradiation and five underwent double-pass irradiation, after which skin samples were collected from the right and left axillae for pathological analysis. Samples were taken in a consistent manner from Patient 6 onwards and a comparative study of five single-pass and five double-pass patients was conducted (n = 10).

RESULTS: Histopathological analysis showed destruction and fibrosis in addition to necrosis and damage to the adipose tissue in apocrine and eccrine sweat glands. In the superficial microvasculature, blood vessel wall damage and thrombus formation were observed as well as damage in the hair follicles and hair bulbs. No obvious damage was observed in the epidermis and nerves. The amount of damage to sweat glands was higher in patients undergoing double-pass instead of single-pass irradiation.

CONCLUSION: From a histopathological point of view, microwave energy-based irradiation therapy can be considered efficient, as there was no damage to epidermis and nerves and favorable destruction of apocrine and eccrine glands. As the amount of damaged sweat glands was higher after double-pass irradiation, it can be considered more effective than single-pass irradiation. Lasers Surg. Med. © 2021 Wiley Periodicals LLC.

Comparison of EQ-5D-3L and metabolic components between patients with hyperhidrosis and the general population: a propensity score matching analysis

Qual Life Res. 2021 May 11. doi: 10.1007/s11136-021-02856-8. Online ahead of print.

ABSTRACT

PURPOSE: It is important to understand the characteristics of patients with hyperhidrosis, which are different from the general population, for treating hyperhidrosis. Sympathetic overactivity, which might play an important role in hyperhidrosis, can contribute to metabolic diseases and the decreased quality of life (QoL). We compared the metabolic components and health-related QoL between patients with hyperhidrosis and the general population.

METHODS: We conducted a case-control study and compared the characteristics of the patients (N = 196) with hyperhidrosis and propensity score-matched controls (N = 196) selected from the Korean National Health and Nutrition Examination Survey. Metabolic components and EQ-5D-3L (EQ-5D) index were compared using a two-way mixed analysis of covariance after adjusting for confounders.

RESULTS: Patients with hyperhidrosis had significantly higher waist circumference (estimated mean values ± SD for patients and the control group, 85.5 ± 10.8 cm vs 81.3 ± 10.3 cm, p < 0.001), blood pressure (SBP, 121.1 ± 16.9 vs 111.7 ± 10.3, p < 0.001 AND DBP, 77.5 ± 12.8 vs 73.6 ± 8.6, p < 0.001, respectively), fasting glucose (97.1 ± 11.3 vs 91.5 ± 9.2, p < 0.001), and the number of components of metabolic syndrome (1.4 ± 1.3 vs 1.0 ± 1.2, p = 0.002), and significantly lower estimated glomerular filtration rate (144.3 ± 53.2 vs 158.3 ± 55.7, p = 0.002) and EQ-5D values (estimated mean values (standard error) for patients and the control group, 0.92 (0.01) vs 0.97 (0.01), p < 0.001) compared to the control group after adjustment.

CONCLUSION: The patients with hyperhidrosis had more central obesity and unfavorable metabolic parameters and a lower EQ-5D index compared with the general population, emphasizing clinical importance of hyperhidrosis to be cured in aspect of metabolic components as well as patients’ QOL.

Management of Primary Focal Hyperhidrosis: An Algorithmic Approach

J Drugs Dermatol. 2021 May 1;20(5):523-528. doi: 10.36849/JDD.5774.

ABSTRACT

Hyperhidrosis (HH) is defined as perspiration beyond the level required to maintain temperature regulation. HH affects nearly 4.8% of the population in the United States. It can have a great impact on patient&rsquo;s quality of life by disturbing daily activity, performance, confidence, social interactions, and mental health. In the majority of patients with HH (93%), the etiology of excess sweating is idiopathic, which classifies it as primary focal HH. Mild HH may be controlled with topical antiperspirants and lifestyle modifications. Based on the location of involvement, iontophoresis and botulinum toxin may be considered if the patient does not respond to topical therapies. Despite minimizing sweating, chronic use of systemic anticholinergics, in particular oxybutynin, may result in detrimental adverse effects such as dementia. Local surgery, radiofrequency, microwave, and lasers are other potential modalities for HH. Sympathectomy can be a last resort for the treatment of focal HH of the palmar, plantar, axillary, and craniofacial areas after failure of less invasive therapeutic options. In this review, we conducted a comprehensive search in the PubMed electronic database to summarize an algorithmic approach for the treatment of HH. This can help broaden options for managing this difficult disease. J Drugs Dermatol. 20(5): doi:10.36849/JDD.5774.

Paroxysmal localized Hyperhidrosis, a case-report: When excessive sweating occurs in combination with severe headaches

Cephalalgia. 2021 May 2:3331024211006843. doi: 10.1177/03331024211006843. Online ahead of print.

ABSTRACT

BACKGROUND: Paroxysmal localized hyperhidrosis is a rare disorder of the central autonomic nervous system. No association between paroxysmal hyperhidrosis and severe headache has been previously described in literature.Case description: A 65-year-old woman with idiopathic paroxysmal localized hyperhidrosis combined with severe holocranial headache attacks is described in this case report. Extensive diagnostic testing by means of laboratory examinations, 24-hour urinalyses, chest X-ray, abdominal ultrasound and computed tomography scans, and brain and spinal cord magnetic resonance imaging could not identify an underlying disorder. A diagnosis of idiopathic paroxysmal localized hyperhidrosis was made, and the patient was successfully treated with clonidine 0.075 mg three times a day, without any side effects.

CONCLUSION: Paroxysmal localized hyperhidrosis is a rare central autonomic nervous system disorder that can occur in combination with severe headache. Both the headache and paroxysmal hyperhidrosis complaints were treated effectively with clonidine in the patient described in this case-report.
