Adv Clin Exp Med. 2023 May 22. doi: 10.17219/acem/162178. Online ahead of print.

ABSTRACT

BACKGROUND: The regulatory effect of integrin β6 (ITGB6) on sweat gland cells in primary palmar hyperhidrosis (PPH) remains unclear.

OBJECTIVES: This study investigated the involvement of ITGB6 in the pathogenesis of PPH.

MATERIAL AND METHODS: Sweat gland tissues were collected from PPH patients and healthy volunteers. The expression levels of ITGB6 in sweat gland tissues were detected with quantitative polymerase chain reaction (qPCR), western blot and immunohistochemical staining. Sweat gland cells were extracted from PPH patients, and identified with immunofluorescence staining of CEA and CK7. The expression of aquaporin 5 (AQP5) and Na-K-Cl cotransporter 1 (NKCC1) in primary sweat gland cells that overexpress ITGB6 were also detected. Through a series of bioinformatic methods, differentially expressed genes in sweat gland tissues were examined and validated via comparing PPH samples and controls. The key proteins and biological functions enriched in PPH were determined using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses.

RESULTS: The ITGB6 was upregulated in sweat gland tissues of PPH patients compared to that of healthy volunteers. The CEA and CK7 were positively expressed in sweat gland cells extracted from PPH patients. The overexpression of ITGB6 upregulated AQP5 and NKCC1 protein expression in the sweat gland cells of PPH patients. A total of 562 differentially expressed mRNAs were identified using high-throughput sequencing (394 upregulated, 168 downregulated), which were mainly active in the chemokine and Wnt signaling pathways. After verification with qPCR and western blot, the overexpression of ITGB6 significantly upregulated CXCL3, CXCL5, CXCL10, and CXCL11, and downregulated Wnt2 mRNA and protein expression in sweat gland cells.

CONCLUSIONS: The ITGB6 is upregulated in PPH patients. It may be involved in the pathogenesis of PPH by upregulating AQP5, NKCC1, CXCL3, CXCL5, CXCL10, and CXCL11, and downregulating Wnt2 expression in sweat glands.

Evaluation of quality of life (QOL) of young patients with primary hyperhidrosis (PH) before and after endoscopic thoracic sympathectomy (ETS)

J Am Acad Dermatol. 2023 May;88(5):e197-e201. doi: 10.1016/j.jaad.2015.10.048.

ABSTRACT

BACKGROUND: Primary hyperhidrosis (PH) affects young patients and may cause emotional distress and a negative quality of life (QOL).

OBJECTIVE: We sought to evaluate the QOL of children and adolescents with PH treated by endoscopic thoracic sympathectomy.

METHODS: A study of 220 patients was performed, based on submitted QOL questionnaires from their first consultation. Patients were evaluated within 1 week and 24 months after surgery.

RESULTS: Before endoscopic thoracic sympathectomy, the QOL in relation to PH was declared very poor by 141 patients, and poor by the remaining 79 (P = .552). Postoperative cure was reported in 100% of palmar and axillary PH cases, and in 91.7% of facial PH. After 24 months, the QOL was described as much better by 212 patients, a little better by 6 patients, and 2 patients reported no change.

LIMITATIONS: Convenience sampling was used and patients were taken from private practice only, raising the possibility of bias in gathering the data.

CONCLUSION: Onset of PH symptoms was mainly before the age of 10 years and substantially affected daily activities. Endoscopic thoracic sympathectomy cured PH and promoted significant improvement in the QOL of these young patients.

Comparison of the efficacy of ETS with different segments for palmar, axillary and plantar hyperhidrosis

BMC Surg. 2023 Apr 11;23(1):82. doi: 10.1186/s12893-023-01976-x.

ABSTRACT

BACKGROUND: To compare the near and long-term outcomes of endoscopic thoracic sympathectomy (ETS) for palmar, axillary and plantar hyperhidrosis.

METHODS: We retrospectively analyzed the clinical data of 218 patients with hyperhidrosis who were admitted to the Department of Thoracic Surgery of Gansu Provincial People’s Hospital for surgical treatment from April 2014 to August 2021. The patients were divided into three groups according to the method of ETS and the perioperative clinical data and postoperative follow-up data were collected to compare the near and long term outcomes of the three groups.

RESULTS: There were 197 eligible patients at follow-up, 60 patients in the R4 cut-off group, 95 patients in the R3 + R4 cut-off group and 42 patients in the R4 + R5 cut-off group. There were no statistically significant differences in baseline indicators such as sex, age and positive family history among the three groups (P > 0.05). There was no statistically significant difference between the three groups in terms of operative time (P = 0.148), intraoperative bleeding (P = 0.308) and postoperative hospital stay (P = 0.407). Postoperatively, all three groups showed significant relief of palmar hyperhidrosis symptoms, with the R3 + R4 group having an advantage in terms of relief of axillary hyperhidrosis symptoms, patient satisfaction and quality of life index at 6 months postoperatively and the R4 + R5 group having an advantage in terms of relief of plantar hyperhidrosis symptoms. The difference in compensatory hyperhidrosis at 12 months postoperatively was not statistically significant among the three groups (P = 0.867), but the incidence was higher in the R3 + R4 and R4 + R5 groups than that in the R4 group.

CONCLUSION: Patients with simple palmar hyperhidrosis can first consider R4 cut-off treatment; R3 + R4 cut-off is more effective in treating palmar hyperhidrosis combined with axillary hyperhidrosis; R4 + R5 cut-off is more effective in treating palmar hyperhidrosis combined with plantar hyperhidrosis. However, patients need to be informed that R3 + R4 and R4 + R5 dissection may increase the risk of severe compensatory hyperhidrosis after surgery.

Anatomical variations of the thoracic sympathetic ganglions and their effects on sympathicotomy for primary palmar hyperhidrosis

Clin Auton Res. 2023 Apr 5. doi: 10.1007/s10286-023-00932-2. Online ahead of print.

ABSTRACT

PURPOSE: The results and side effects of sympathicotomy for primary palmar hyperhidrosis (PPH) can vary due to anatomical variations of the sympathetic ganglions. The aim of our study was to clarify anatomical variations of the sympathetic ganglions by near-infrared (NIR) thoracoscopy and determine their effects on sympathicotomy for PPH.

METHODS: The cases of 695 consecutive patients with PPH treated with either R3 or R4 sympathicotomy either by normal thoracoscopy or by NIR fluorescent thoracoscopy between March 2015 and June 2021 were retrospectively reviewed and followed up.

RESULTS: The variation rate of third and fourth ganglions was 14.7% and 13.3% on the right side and 8.3% and 11.1% on the left side. Real T3 sympathicotomy (RTS3) was more effective than real T4 sympathicotomy (RTS4) in the short-term and long-term follow-up (p < 0.001 and p < 0.001, respectively). RTS3 was more satisfactory than RTS4 in the long-term follow-up (p = 0.03), but no significant difference was found in the short-term follow-up (p = 0.24). The incidence and severity of compensatory hyperhidrosis (CH) in the areas of the chest and back in the RTS4 group were significantly lower than those in the RTS3 group according to both the short-term results (12.92% vs. 26.19%, p < 0.001; 17.97% vs. 33.33%, p = 0.002, respectively) and the long-term results (19.66% vs. 28.57%, p = 0.017; 21.35% vs. 34.52%, p < 0.001, respectively).

CONCLUSIONS: RTS3 may be more effective than RTS4 for PPH. However, RTS4 appears to be associated with a lower incidence and severity of CH in the areas of the chest and back than RTS3. NIR intraoperative imaging of thoracic sympathetic ganglions may improve the quality of sympathicotomy surgeries.

Oxybutynin gel versus nanoemulgel for treating primary palmar hyperhidrosis: A pilot double-blind randomized controlled trial

J Cosmet Dermatol. 2023 Mar 31. doi: 10.1111/jocd.15715. Online ahead of print.

ABSTRACT

INTRODUCTION: Palmar hyperhidrosis or excessive palmar sweating can reduce one’s quality of life as it is associated with significant physical and occupational disabilities. We compared the gel and nanoemulgel of oxybutynin in treating these patients.

MATERIALS AND METHODS: This pilot study was performed as a double-blind controlled randomized clinical trial at Shahid Faghihi Hospital, Shiraz, Iran. In two randomly allocated groups of 15, patients diagnosed with primary palmar hyperhidrosis by an attending dermatologist applied half a fingertip (roughly 0.25 g) of 1% oxybutynin topical gel or 1% oxybutynin nanoemulgel to both palms every 12 h for one month. The Hyperhidrosis Disease Severity Scale (HDSS), Visual Analog Scale (VAS), and Dermatology Life Quality Index (DLQI) were used to assess the patients at the beginning and end of the study. Statistical analysis was performed using SPSS version 25.

RESULTS: The groups were similar in terms of age (p = 0.800), sex (p = 0.096), and baseline HDSS, VAS, and DLQI scores. The mean HDSS scores decreased significantly (p = 0.001) over time in patients receiving the gel (3.00 ± 1.00 vs. 2.33 ± 0.61) or nanoemulgel (2.92 ± 0.82 vs. 2.14 ± 0.53), without a significant difference between the groups. The same was true for the VAS and DLQI scores. Three patients in each group experienced transient, self-limited anticholinergic side effects (p = 0.983).

CONCLUSION: Oxybutynin gel and nanoemulgel offer equal safety and similar efficacy in reducing the disease severity and increasing the quality of life of patients with palmar hyperhidrosis.

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

J Am Acad Dermatol. 2023 Mar 27:S0190-9622(23)00511-X. doi: 10.1016/j.jaad.2023.03.025. Online ahead of print.

ABSTRACT

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 (AEs) occurred, and no AEs 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.

Impact of endoscopic thoracic R4 sympathicotomy combined with R3 ramicotomy for primary palmar hyperhidrosis

Front Surg. 2023 Feb 24;10:1144299. doi: 10.3389/fsurg.2023.1144299. eCollection 2023.

ABSTRACT

BACKGROUND: Endoscopic thoracoscopic sympathectomy (ETS) is the preferred method for treating primary palmar hyperhidrosis (PPH) that bears the risk of compensatory hyperhidrosis (CH) following surgery. The current study aims to evaluate the effectiveness and safety of an innovative surgical procedure of ETS.

METHODS: A survey of the clinical data of 109 patients with PPH who underwent ETS in our department from May 2018 to August 2021 was retrospectively conducted. The patients were organized into two groups. Group A underwent R4 sympathicotomy combined with R3 ramicotomy. Group B underwent R3 sympathicotomy. Patients were followed up to evaluate the safety, effectiveness and the incidence of postoperative CH of the modified surgical approach.

RESULTS: A total of 102 patients completed follow-up, and seven of the total enrolled patients were lost to follow-up, with a loss rate of 6% (7/109). Among these, Group A constitutes 54 cases, group B constitutes 48 cases, and the mean follow-up was 14 months (interquartile range 12-23 months). There was no statistically difference in surgical safety, postoperative efficacy, and postoperative quality of life (QoL) score between group A and group B (p > 0.05). The score of the psychological assessment was higher (p = 0.004) in group A (14.15 ± 2.06) compared to group B (13.30 ± 1.86). The incidence of CH in group A was lower than in group B (p = 0.019).

CONCLUSION: R4 sympathicotomy combined with R3 ramicotomy is safe and effective for PPH treatment, along with a reduced incidence of postoperative CH rate and improved postoperative psychological satisfaction.

Postoperative diaphragmatic hernia following endoscopic thoracic sympathectomy for primary palmar hyperhidrosis: A case report

Front Surg. 2023 Jan 6;9:1059604. doi: 10.3389/fsurg.2022.1059604. eCollection 2022.

ABSTRACT

Postoperative diaphragmatic hernia (DH) following endoscopic thoracic sympathectomy for primary palmar hyperhidrosis is extremely rare. We present a 21-year-old female patient who developed a left DH with herniation of the stomach and gastric perforation on the first postoperative day after undergoing bilateral video-assisted thoracoscopic sympathectomy R4 ablation. She complained of severe dyspnea and chest pain, and an emergency chest x-ray and computed tomography revealed left pleural effusion, collapsed lung, and left DH, which allowed the stomach to herniate into the chest. Emergency thoracoscopic surgery was performed. We repaired the diaphragmatic defect intraoperatively and replaced the stomach with the peritoneal cavity from the thoracic field. The patient was discharged without complications. She did not present with recurrent symptoms at the 3-month follow-up. Postoperative DH should be considered when patients complain of gastrointestinal or respiratory symptoms after sympathectomy, although it is very rare.

Efficacy, Safety and Quality of Life of Oxybutynin versus Aluminum Chloride Hexahydrate in Treating Primary Palmar Hyperhidrosis

Indian J Dermatol. 2022 May-Jun;67(3):222-227. doi: 10.4103/ijd.IJD_799_20.

ABSTRACT

BACKGROUND: Palmar hyperhidrosis is characterized by excessive sweating beyond the physiological needs of the patient’s body and the most frequent form is primary or essential. Different treatments protocols have been proposed to control or decrease sweating.

AIMS AND OBJECTIVES: This study aimed to compare the efficacy and safety of oral oxybutynin versus topical aluminum chloride hexahydrate (ACH) in treating primary palmar hyperhidrosis. Also, to assess quality of life (QOL) as a measure of improvement of hyperhidrosis state.

MATERIALS AND METHODS: Patients were randomized using the block randomization with sealed envelope method into two treatment groups; oral oxybutynin group and topical ACH group. Hyperhidrosis Disease Severity Scale (HDSS) was used as a primary outcome measure to assess the efficacy of the drug in both groups. Clinical grading and the QOL were used as secondary outcome measures. The safety was evaluated by recording side effects in the follow-up visits.

RESULTS: HDSS, clinical grading and QOL score showed a statistically significant improvement in the oral oxybutynin groups. One week after stoppage of treatment, the symptoms recurred again in both groups with return of HDSS and QOL scores to pretreatment levels. The most common side effects were dry mouth (65.8%) and itching (65.0%) for oral oxybutynin group and topical ACH group; respectively.

CONCLUSION: Treatment of primary palmar hyperhidrosis with oxybutynin is a good initial alternative for treatment given that it gives better results and much more improvement in QOL when compared to topical ACH. QOL questionnaire and clinical grading should also be considered as useful tools in the assessment of response to treatment.
