Total glucosides of paeony capsule plus compound glycyrrhizin tablets for the treatment of severe alopecia areata in children: a randomized controlled trial

Botanical extract combined with minoxidil improve hidrotic ectodermal dysplasia caused by p.G11R mutations: a case report

PURPOSE

We aim to explore a potential treatment strategy for hair loss.

MATERIALS AND METHODS

A male 6-year-old child was diagnosed with hidrotic ectodermal dysplasia 2 (HED2) caused by GJB6 (p.G11R) mutations. He presented at our clinic with diffuse thinning and fine and brittle hair since birth. Additionally, the child exhibited abnormal development of teeth, fingernails, and toenails. The condition of the child's hair had not improved significantly with age. He was treated with botanical extracts combined with Minoxidil.

RESULTS

After one and a half months of treatment, the patient showed remarkable hair growth.

CONCLUSIONS

Our team has previously used botanical extracts in combination for the treatment of autosomal recessive wooly hair in children. In the present case, treatment with botanical extract combined with minoxidil was found to be equally efficacious. This case report provides valuable information for future studies on the use of botanical extracts in treating hair loss, as well as a safe and effective potential treatment strategy for children with congenital alopecia.

Efficacy and safety of compound glycyrrhizin in the patients with vitiligo: a systematic review and meta-analysis

OBJECTIVE

Compound glycyrrhizin (CG) is widely used to treat vitiligo in China, and the efficacy and adverse events (AEs) of CG for vitiligo need further analysis. This study aimed to systematically reevaluate the efficacy and safety of CG in the patients with vitiligo.

RESEARCH DESIGN AND METHODS

Eight literature databases were searched up to 31 December 2022, and randomized controlled trials which compared CG plus conventional treatments with conventional treatments alone were included.

RESULTS

17 studies with 1492 patients were included. The pooled results showed that the combination of CG and conventional treatments was superior to conventional treatments alone in the total efficacy rate (risk ratio (RR) = 1.54, 95% confidence interval (CI) = 1.40 to 1.69, P < 0.00001), cure rate (RR = 1.62, 95%CI = 1.32 to 1.99, P < 0.00001), the levels of serum IL-6, TNF-α, IL-17, and TGF-ß, and the ratio of CD4⁺/CD8⁺ T cell in blood. Moreover, few patients suffered from the mild and tolerable AEs of CG.

CONCLUSIONS

CG plus conventional treatments is an effective treatment for vitiligo with mild and tolerable AEs. More high-quality and large-sample studies are required in the future to provide more evidence of CG for vitiligo.

Complementary and alternative medicine for alopecia areata: A systematic review

BACKGROUND

Despite high use of complementary and alternative medicine (CAM) for alopecia areata (AA), efficacy and safety remain unclear.

OBJECTIVE

To identify all CAM therapies studied for treatment of AA. Outcomes of interest included disease course and psychologic well-being.

METHODS

PubMed and Embase were searched to identify English articles containing original data investigating CAM in individuals with AA from 1950-2018. Quality was assessed with Oxford Centre for Evidence Based Medicine criteria.

RESULTS

Of 1015 initial citations, 16 articles met inclusion criteria: 5 randomized controlled trials, 5 prospective controlled cohorts, 4 prospective noncontrolled cohorts, 1 retrospective cohort, and 1 case series. CAM therapies with best evidence and efficacy for hair growth in AA include essential oil aromatherapy, topical garlic, and oral glucosides of peony with compound glycyrrhizin. Hypnosis and mindfulness psychotherapy represent low-quality evidence for improvement of psychologic and quality of life outcomes. Adverse events were rare and mild for all therapies evaluated.

LIMITATIONS

Inconsistent or poorly reported study methodology and nonstandardized outcomes limit the conclusions that can be made from these studies.

CONCLUSIONS

This work serves to inform physician treatment of patients with AA seeking CAM while encouraging further investigation into these therapies to address some of the therapeutic challenges of AA.

Evaluation of the Safety and Effectiveness of Nutritional Supplements for Treating Hair Loss: A Systematic Review

Importance

Despite the widespread use of nutritional supplements and dietary interventions for treating hair loss, the safety and effectiveness of available products remain unclear.

Objective

To evaluate and compile the findings of all dietary and nutritional interventions for treatment of hair loss among individuals without a known baseline nutritional deficiency.

Evidence Review

The MEDLINE, Embase, and CINAHL databases were searched from inception through October 20, 2021, to identify articles written in English with original findings from investigations of dietary and nutritional interventions in individuals with alopecia or hair loss without a known baseline nutritional deficiency. Quality was assessed with Oxford Centre for Evidence Based Medicine criteria. Outcomes of interest were disease course, both objectively and subjectively measured. Data were evaluated from January 3 to 11, 2022.

Findings

The database searches yielded 6347 citations to which 11 articles from reference lists were added. Of this total, 30 articles were included: 17 randomized clinical trials (RCTs), 11 clinical studies (non-RCT), and 2 case series studies. No diet-based interventional studies met inclusion criteria. Studies of nutritional interventions with the highest-quality evidence showed the potential benefit of Viviscal, Nourkrin, Nutrafol, Lamdapil, Pantogar, capsaicin and isoflavone, omegas 3 and 6 with antioxidants, apple nutraceutical, total glucosides of paeony and compound glycyrrhizin tablets, zinc, tocotrienol, and pumpkin seed oil. Kimchi and cheonggukjang, vitamin D3, and Forti5 had low-quality evidence for disease course improvement. Adverse effects were rare and mild for all the therapies evaluated.

Conclusions and Relevance

The findings of this systematic review should be interpreted in the context of each study's design; however, this work suggests a potential role for nutritional supplements in the treatment of hair loss. Physicians should engage in shared decision-making by covering the potential risks and benefits of these treatments with patients experiencing hair loss. Future research should focus on larger RCTs with active comparators.

Prediction of the Mechanism of Shaoyao Gancao Decoction in the Treatment of Alopecia Areata by Network Pharmacology and Its Preliminary Verification Study

Objective

To explore the mechanism of Shaoyao Gancao decoction (SGD) in treatment of alopecia areata (AA) by network pharmacology and animal experiments.

Methods

Based on the traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP), the components and targets of SGD were determined. Then, the related targets of AA were retrieved from DrugBank, GeneCards, OMIM, and DisGeNET databases. The intersection of drug targets and disease targets was determined, and the key targets of the protein-protein interaction network were obtained with the String database. Gene Ontology (GO) biological process enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of potential key targets were carried out using the DAVID database using AutoDock for molecular docking verification. Finally, the key pathway was validated by animal experiments.

Results

A total of 102 active components, 212 predicted targets, and 812 AA disease-related targets were obtained. Topological analysis yielded 45 key targets of SGD in the treatment of AA, including IL-6, PTGS2, TNF, VEGFA, CCL2, IL-1B, CXCL8, CASP3, MPO, and IL-10. There were 324 GO entries obtained through GO biological process enrichment analysis, and 20 pathways were obtained through KEGG pathway enrichment analysis, involving the PI3K-Akt signaling pathway, osteoclast differentiation, and Jak-STAT signaling pathway. The molecular docking results showed effective ingredients (quercetin, kaempferol, and 7-methoxy-2-methyl isoflavone) have good docking results with targets (IL-6, PTGS2, and TNF). The results of animal experiments showed that SGD can effectively upregulate the expression of PI3K and AKT proteins.

Conclusion

This is the first in-depth study on the mechanism of SGD's treatment effect in AA using network pharmacology, and preliminary animal experiments verified that it is closely related to the PI3K/AKT signaling pathway. This finding may provide a new basis for SGD's clinical application in AA.

Botanical extracts in combination improves autosomal recessive woolly hair/ hypotrichosis caused by LIPH mutations

Mutation in the lipase H (LIPH) gene is a main reason for autosomal recessive woolly hair (ARWH)/ hypotrichosis [1]. Although some studies reported that topical minoxidil could improve ARWH [2] [3], an effective treatment method for this disease still lacks. In this paper, we reported a case of hair growth in an ARWH patient with a LIPH gene mutation, using combined treatment of botanical extracts, and attempted to explore potential treatment options for ARWH.

Clinical application of compound Glycyrrhizin tablets in the treatment of patients with Simplex Henoch-Schonlein Purpura and its effect on immune function

Objectives:

To investigate the curative effect of Compound Glycyrrhizin Tablets in the adjuvant treatment of simplex Henoch-Schonlein purpura and its influence in improving immune function.

Methods:

In this retrospective study design was used in this study. Eighty newly diagnosed patients with purpura simplex who visited the outpatient department of Baoding First Central Hospital from June 2017 to February 2020 were included. They were randomly divided into treatment group and control group. The two groups were provided with the same conventional comprehensive treatment. Patients in the treatment group received oral administration of Compound Glycyrrhizin Tablets on the basis of conventional treatment. The clinical efficacy of the treatment group and the control group were compared according to the time and effect of purpura regression, followed by the comparison of changes of T cell subsets before and after treatment.

Results:

The total effective rate of the treatment group was 92.5%, which was higher than that of the control group (77.5%) (P < 0.05). The purpura subsidence time of effective patients in treatment group was shorter than that in control group (P < 0.05). There was no significant difference in lymphocyte subsets between the treatment group and the control group before treatment. After treatment, the proportion of CD4+ cells and CD4+/CD8+ cells in the treatment group were obviously higher than that in the control group, and the count of CD8+ cells was evidently lower than that in the control group (P < 0.05).

Conclusions:

Compound Glycyrrhizin is effective in the adjuvant treatment of simplex Henoch-Schonlein purpura without obvious adverse reactions, which is valuable for clinical application as an adjuvant.

Compound glycyrrhizin combined with antihistamines for chronic urticaria: A protocol for systematic review and meta analysis

BACKGROUND

To investigate the efficacy and safety of compound glycyrrhizin (CG) combined with antihistamines in the treatment of chronic urticaria (CU).

METHODS

We will use computers to search all databases including Medline, Embase, Pubmed, Web of Science and Cochrane Central Register of Controlled Trials and China's 4 databases: China National Knowledge Infrastructure Database, China Biomedical Literature Database, China Science Journal Database, and Wanfang Database. Find data from creation date to July 2020. In addition, we will manually search the list of medical journals as a supplement. The scope of the search included randomized controlled clinical studies related to CG combined with antihistamines for CU. The primary outcome is the disease activity control. Secondary outcomes include response rate, adverse events, and recurrence rates. The Cochrane RevMan V5.3 Deviation Assessment Tool will be used to assess bias assessment risk, data integration risk, meta-analysis risk, and subgroup analysis risk (if conditions are met). The average difference, standard mean difference, and binary data will be used to represent continuous results.

RESULTS

This study will comprehensively review the existing evidence on CG combined with antihistamines for CU.

CONCLUSION

This systematic review will provide a basis for judging the effectiveness and safety of CG combined with antihistamines in the treatment of CU.

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of Compound Glycyrrhizin Capsules Combined with a Topical Corticosteroid in Adults with Chronic Eczema

BACKGROUND

Glycyrrhizin is widely used in skin disorders, such as psoriasis, alopecia areata, and allergic diseases, but has not been extensively studied in patients with chronic eczema.

OBJECTIVE

To evaluate the efficacy and safety of oral compound glycyrrhizin (OCG) plus topical corticosteroid (TCS) in adults with chronic eczema.

METHODS

This was a multicenter, randomized, double-blind, placebo-controlled study in patients with chronic eczema (n = 199). Randomized participants from 6 centers in China received either 75 mg OCG capsules or placebo capsules three times a day and TCS (i.e., 0.1% mometasone furoate ointment) once a day for 28 days. Efficacy was determined by analyzing the mean change from the baseline using standardized measures including the Investigator's Global Assessment (IGA) score, Eczema Area and Severity Index (EASI), and the visual analogue scale score (VAS) of itching.

RESULTS

Decreases in absolute EASI were significantly greater in the OCG-treated group versus placebo on day 14 (-3.41 ± 1.41 vs. -2.71 ± 1.25, P < 0.001) and day 28 (-7.39 ± 1.71 vs. -6.64 ± 1.75, P=0.003). OCG-treated patients also saw greater benefit in other EASI metrics including EASI-50 (96.8% vs. 87.9%, P=0.021) and EASI-75 (47.9% vs. 21.2%, P < 0.001) on day 28 compared with placebo. The absolute IGA score reductions were also significantly greater in the OCG group than the placebo (all P < 0.05). In addition, proportions of patients who achieve clear (0) IGA scores or almost clear (1) IGA scores were significantly higher in the treated group than placebo on day 14 (22.8% vs. 6.2%, P=0.001) and day 28 (93.5% vs. 79.4%, P=0.005). Moreover, the proportions of patients with reduced pruritus were significantly greater in the treated group than placebo on day 28 (94.7% vs. 83.8%, P=0.016) and eczema recurrence was notably less in the OCG group versus placebo (3.19% vs. 12.12%, P=0.021). Eleven patients experienced adverse events, but there was no significant difference in the proportion of patients affected (3.0% vs. 8.5%, P > 0.05). The most common adverse events were edema of both lower limbs.

CONCLUSION

For adults with chronic eczema, OCG capsules combined with TCS is an effective and well-tolerated treatment, suggesting that OCG may be a useful nonsteroidal agent with an additional effect for the treatment of chronic eczema by TCS.

A Review of the Pharmacological Efficacy and Safety of Licorice Root from Corroborative Clinical Trial Findings

Since ancient times, licorice, the root of Glycyrrhiza glabra, has been known to have a wide spectrum of therapeutic effects. Glycyrrhizin is cleaved to glycyrrhizic acid, which is subsequently converted to glycyrrhetic acid by human intestinal microflora. Glycyrrhetic acid is a potent inhibitor of 11β-hydroxysteroid dehydrogenase (11β-HSD) and performs a range of corticosteroid-like activities. The pharmacologic effects of licorice contribute to its anti-inflammatory, antioxidative, anti-allergenic, and antimicrobial properties. Licorice has been used to treat liver disease, gastrointestinal disorders, oral disease, and various skin disorders and has been used in gum, candy, herbs, alcoholic beverages, and food supplements. Licorice and its extracts, especially glycyrrhizin, can be taken orally, through the skin (in the form of gels and oils), and intravenously. Licorice demonstrates mineralocorticoid-like activity not only by inhibiting 11β-HSD2, but also by binding to a mineralocorticoid receptor, leading to potentially adverse risks of mineralocorticoid-like overactivity. Chronic use of licorice can lead to hypokalemia and hypertension, and some people are more sensitive to licorice exposure. Based on clinical trials, this review summarizes the positive effects of licorice and other reported side effects.

Combination therapy of orally administered glycyrrhizin and UVB improved active-stage generalized vitiligo

Glycyrrhizin has been used clinically for several years due to its beneficial effect on immunoglobulin E (IgE)-induced allergic diseases, alopecia areata and psoriasis. In this study, glycyrrhizin, ultraviolet B light (UVB) or a combination of both were used to treat active-stage generalized vitiligo. One hundred and forty-four patients between the ages of 3 and 48 years were divided into three groups: group A received oral compound glycyrrhizin (OCG); group B received UVB applications twice weekly, and group C received OCG+UVB. Follow-ups were performed at 2, 4, and 6 months after the treatment was initiated. The Vitiligo Area Scoring Index (VASI) and the Vitiligo Disease Activity (VIDA) instrument were used to assess the affected body surface, at each follow-up. Results showed that 77.1, 75.0 and 87.5% in groups A, B and C, respectively, presented repigmentation of lesions. Responsiveness to therapy seemed to be associated with lesion location and patient compliance. Adverse events were limited and transient. This study showed that, although the three treatment protocols had positive results, OCG and UVB combination therapy was the most effective and led to improvement in disease stage from active to stable.

Possible alternative therapies for oral lichen planus cases refractory to steroid therapies

Oral lichen planus (OLP) is a chronic inflammatory disorder with a multifactorial etiopathogenesis. Immune dysregulation plays a critical role in the development and progression of this disease. Patients' lives may be affected by pain caused by atrophic-erosive lesions. Given the obscure etiology, treatment is usually symptomatic. Topical steroids remain the mainstay of management. However, their therapeutic benefits are not always evident. There are substantial data on the possible therapeutic strategies that are effective in OLP cases refractory to steroids. This review provides an overview of the current approaches for the management of steroid-refractory OLP. The miscellaneous treatment regimens include tacrolimus, pimecrolimus, thalidomide, low-level laser therapy, photodynamic therapy, and surgical excision. Some results obtained from these studies were promising. However, further studies, especially randomized controlled trials with strict inclusion and exclusion criteria and larger sample sizes, are required for the evaluation of the long-term safety and efficacy of these therapies.

Successful treatment of necrobiotic xanthogranuloma with total glucosides of paeony

Necrobiotic xanthogranuloma (NXG) is a rare granulomatous condition that is often associated with a paraproteinemia and in some cases multiple myeloma. We report a case of isolated NXG that responded very well to total glucosides of paeony treatment. Characteristic clinical and histological features of NXG are presented, as well as a discussion regarding management and the use of glucosides of paeony. Treatment with total glucosides of paeony is an effective, safe treatment, which avoids the side effects associated with systemic corticosteroid or cytotoxic agent therapy.
