Hyperhidrosis: disease aetiology, classification and management in the light of modern treatment modalities

Postepy Dermatol Alergol. 2022 Apr;39(2):251-257. doi: 10.5114/ada.2022.115887. Epub 2022 May 9.

ABSTRACT

Hyperhidrosis is a disorder of sweat glands characterized by overproduction of sweat, which is inadequate to the thermoregulatory needs of the body system. Owing to the heavy social and economic burden of the disproportionate perspiration, current treatment methods still do not seem to be sufficient enough to reach patients’ expectations. Therefore, the researchers continue a robust pursuit of novel therapy modalities such as topical treatment methods, oral agents, minimally-invasive medical approach and surgical techniques. In this review article authors summarise the disease outline with the emphasis on the new era of hyperhidrosis treatment methods.

Open-Label Cohort Study to Evaluate Efficacy and Safety of Application of Glycopyrronium Cloth, 2.4% for Palmar Hyperhidrosis

J Drugs Dermatol. 2022 May 1;21(5):488-495. doi: 10.36849/JDD.6688.

ABSTRACT

BACKGROUND: Hyperhidrosis of the palms has a significant negative impact on quality of life. There is no FDA-approved treatment; however, clinicians often use glycopyrronium cloth off-label for this indication despite the lack of published guidance on optimal method of application for treatment of palms.

OBJECTIVE: To compare the safety and efficacy of 4 different methods of application of glycopyrronium cloth to give clinicians guidance when treating palmar hyperhidrosis.

STUDY DESIGN: This study, conducted completely virtually using live interactive telemedicine, compared application times of 15 minutes, 30 minutes, and overnight without occlusion and 30 minutes under occlusion. The primary endpoint was a decrease in the mean of the Hand Severity Score (HHS) after 4 weeks of once-daily application. Safety data, including local skin reactions and other adverse events, were tabulated by cohort.

RESULTS: Of the application times and methods tested, 30 minutes without occlusion produced the greatest decrease in the HHS with an acceptable safety profile. The most common adverse event was unilateral mydriasis, which presumably occurred from inadvertent introduction of study drug into the eye despite multiple warnings to the subjects to avoid eye contact. A few subjects had adverse events presumably due to systemic absorption of the drug similar to those seen in the pivotal trials for treatment of axillary hyperhidrosis.

CONCLUSION: Glycopyrronium cloth can be used successfully to treat palmar hyperhidrosis. Occlusion for 30 minutes had the poorest response presumably due to the increased sweating causing dilution of the study drug.

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

Drug Deliv Transl Res. 2022 Apr 20. doi: 10.1007/s13346-022-01164-z. Online ahead of print.

ABSTRACT

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.

Two-week prospective observational study of 5% sofpironium bromide gel in Japanese patients with primary axillary hyperhidrosis

J Dermatol. 2022 Apr 8. doi: 10.1111/1346-8138.16384. Online ahead of print.

ABSTRACT

In 2020, 5% sofpironium bromide (ECCLOCK® ) gel (hereinafter referred to as sofpironium) was approved in Japan for the topical treatment of primary axillary hyperhidrosis. A phase III study of sofpironium demonstrated the efficacy and safety of sofpironium; however, no study has assessed its early efficacy at <6 weeks after starting treatment. Therefore, to assess the earlier effectiveness of sofpironium, we conducted a 2-week, single-center, exploratory, prospective, observational study in Japanese patients with primary axillary hyperhidrosis. Patients aged ≥20 years and satisfying with a Hyperhidrosis Disease Severity Scale (HDSS) score of 3 or 4 at baseline were eligible for the study. The primary endpoint for the effectiveness was change in the proportion of patients with a HDSS score of 1, 2, 3, or 4 during the 2-week study period. In 80 patients included in the full analysis set (FAS), there were more women than men (93.8% vs. 6.3%), and the mean age (±standard deviation [SD]) was 33.3 ± 9.4 years. In the FAS, the proportion of patients with a HDSS score of 1 or 2 was 55.0% on day 7, and statistically significant changes were observed after day 3 compared to baseline (p < 0.05). Mean HDSS scores (±SD) were significantly decreased from baseline value of 3.5 ± 0.5 to 2.4 ± 0.9 on day 7 (p < 0.001). The median period for sofpironium treatment to achieve a HDSS score of 1 or 2 for a continuous 2 days was 6 days (95% confidence interval, 4-8). Safety was evaluated in 92 patients in the safety analysis set, and no adverse events were reported during the study period of 2 weeks. These results suggest that after 1-week treatment with sofpironium for patients with a HDSS score of 3 or 4, approximately 50% of the patients can achieve a HDSS score of 1 or 2, which is a clinically significant improvement for the patients.

Clinical utility of botulinum toxin type A local injection therapy for head and forehead hyperhidrosis

J Dermatol. 2022 Apr 7. doi: 10.1111/1346-8138.16368. Online ahead of print.

ABSTRACT

Head and forehead hyperhidrosis (HFH) is a disease that causes a large amount of sweating from the head region, and it significantly reduces patients’ quality of life. Only a few reports have shown the effectiveness of botulinum toxin type A (BTX-A) local injection therapy (BTX-A therapy) for HFH. To clarify the benefits of BTX-A for HFH, BTX-A therapy was performed in 15 patients, and its efficacy was evaluated. The amount of sweating was measured by the ventilation capsule method and Minor’s iodine-starch test. Evaluation was also performed using the Hyperhidrosis Disease Severity Scale (HDSS) and the Dermatology Life Quality Index (DLQI). In most cases, a remarkable antiperspirant effect was observed from 2 weeks after the injection, and the effect lasted for approximately 30 weeks. HDSS and DLQI improved along with the decrease in sweating. Two patients (13.3%) complained of transient mild ptosis. There were no serious side-effects. This study showed that BTX-A therapy is a safe and effective treatment for HFH.

A Practical Approach to the Diagnosis and Treatment of Palmar Hyperhidrosis

Plast Reconstr Surg Glob Open. 2022 Mar 7;10(3):e4172. doi: 10.1097/GOX.0000000000004172. eCollection 2022 Mar.

ABSTRACT

Palmar hyperhidrosis (PH), a condition characterized by excess sweating of the palms, is a common concern that presents to the plastic surgeon, which can have major impacts on patient confidence and quality of life. While several studies summarize treatment options for hyperhidrosis in general, few outline the therapeutic options available specifically for PH.

METHOD: The authors reviewed the current literature specific to the diagnostic workup and treatment of PH.

RESULTS: In this article, we show a practical approach to managing patients presenting with PH, summarize its main nonsurgical and surgical treatment options, provide a suggested treatment ladder, and outline emerging therapeutic approaches. We suggest that, after diagnosing PH and classifying its severity, nonsurgical treatments (ie, topical antiperspirants, iontophoresis, botulinum toxin A injection, and topical/oral anticholinergics) should be utilized in a stepwise manner. In patients with severe palmar hyperhidrosis who do not respond to nonsurgical treatments, surgical intervention may be warranted, generally in the form of sympathetic denervation.

CONCLUSION: This article provides a clear overview of PH treatment options, stepwise guidelines for physicians, and educational video resources demonstrating botulinum toxin A injections with cryotherapy and nerve blocks.

Cohort study on 20 years’ experience of bilateral video-assisted thoracic sympathectomy (VATS) for treatment of hyperhidrosis in 2431 patients

Sao Paulo Med J. 2022 Feb 21:S1516-31802022005004202. doi: 10.1590/1516-3180.2021.0078.R1.23072021. Online ahead of print.

ABSTRACT

BACKGROUND: Primary hyperhidrosis is a condition characterized by excessive sweating, inconsistent with the needs for thermoregulation.

OBJECTIVE: To assess the effectiveness and the change in the quality of life of patients undergoing bilateral VATS (video-assisted thoracoscopic sympathectomy) for treatment of hyperhidrosis, in a large case series.

DESIGN AND SETTING: Cohort study conducted in a tertiary hospital specializing in hyperhidrosis located in São Paulo, Brazil.

METHODS: A total of 2,431 patients who underwent surgery consisting of bilateral video-assisted thoracoscopic sympathectomy between January 2000 and February 2017 were retrospectively assessed in an outpatient clinic specializing in hyperhidrosis. The patients underwent clinical and quality of life assessments on two occasions: firstly, prior to surgery, and subsequently, one month after the operation. The presence or absence of compensatory hyperhidrosis (CH) and general satisfaction after the first postoperative month were also evaluated.

RESULTS: All the patients operated had poor or very poor quality of life before surgery. In the postoperative period, an improvement in the quality of life was observed in more than 90% of the patients. Only 10.7% of the patients did not present CH, and severe CH occurred in 22.1% of the patients in this sample.

CONCLUSION: Bilateral VATS is a therapeutic method that decreases the degree of sweating more than 90% of patients with palmar and axillary hyperhidrosis. It improves the quality of life for more than 90% of the patients, at the expense of development of CH in approximately 90% of the patients, but not intensely.

Unexpected improvement of hyperhidrosis with cannabidiol

Einstein (Sao Paulo). 2022 Feb 14;20:eRC5795. doi: 10.31744/einstein_journal/2022RC5795. eCollection 2022.

ABSTRACT

Hyperhidrosis is characterized by excessive sweating and it affects almost 5% of the population. The affected age group is wide, and it can affect from children to elderlies. There are two types of hyperhidrosis: generalized and focal. Treatment depends on the symptoms presented. In more severe cases, radiofrequency sympatholysis and bilateral thoracic sympathectomy are the options. However, recurrence is possible or the postoperative appearance of conditions called compensatory hyperhidrosis or reflex hyperhidrosis. We describe two cases of patients treated with Cannabidiol who had significant and unexpected improvement of hyperhidrosis. The first patient received Cannabidiol specific for public presentations at work, and the second patient had a diagnosis of autism spectrum disorder. The hyperhidrosis improved in both patients immediately after using Cannabidiol.

Minimally Invasive Sympathicotomy for Palmar Hyperhidrosis and Facial Blushing: Current Status and the Hyperhidrosis Expert Center Approach

J Clin Med. 2022 Jan 31;11(3):786. doi: 10.3390/jcm11030786.

ABSTRACT

Hyperhidrosis, the medical term for excessive sweating beyond physiological need, is a condition with serious emotional and social consequences for affected patients. Symptoms usually appear in focal areas such as the feet, hands, axillae and face. Non-surgical treatment options such as topical antiperspirants or systemic medications are usually offered as a first step of treatment, although these therapies are often ineffective, especially in severe and intolerable cases of hyperhidrosis. In the treatment algorithm for patients suffering from hyperhidrosis, surgical thoracoscopic sympathicotomy offers a permanent solution, which is particularly effective in the treatment of palmar hyperhidrosis and facial blushing. In this review, we describe the current status of thoracoscopic sympathicotomy for palmar hyperhidrosis and facial blushing. In addition, we share the specific treatment approach, technique and results of our Hyperhidrosis Expert Center. Last, we share recommendations to ensure an effective, reproducible and safe application of single-port thoracoscopic sympathicotomy for palmar hyperhidrosis and facial blushing, based on our extensive experience.
