Efficacy of Herbal Medicine in Hand Osteoarthritis: A Narrative Review.

OBJECTIVE: Osteoarthritis (OA) is one of the most prevalent joint disorders in the world that has placed an enormous economic and social burden on governments and healthcare sectors in many countries. Hand OA (HOA) is the most common peripheral arthritis, which is less investigated than knee and hip OA. Due to limited approved drug choices and adverse effects of long-term use of current regimens, we aimed to review the existing evidence that were used as oral herbal medicine to treat HOA. METHODS: The PubMed database was searched for both observational and interventional studies that have investigated herbal medicine safety and efficacy in HOA, written in English and published between 2010 and 2022. RESULTS: A total of 5 original articles fulfilled the inclusion criteria, and each article assessed a different herbal regimen. Overall, it seems desirable to add specific herbal treatments to the regimen of HOA patients, specifically in case of early stages of HOA. CONCLUSION: Currently, the need for a low-risk alternative treatment in HOA patients is felt more than ever. There are reliable references relating to the safety of Korean red ginseng, GCSB-5, XLGB, and GS-GCu in these patients, although their efficacy was limited. Additionally, herbs like curcumin and Boswellia serrata have positively affected patients with knee osteoarthritis. However, there is a lack of strong evidence supporting their effectiveness in hand osteoarthritis (HOA). This emphasizes the potential benefits that these herbs may have for HOA patients.

Endothelin-1, α-Klotho, 25(OH) Vit D levels and severity of disease in scleroderma patients.

Considering the role of endothelin-1 (ET-1) in tissue remodeling and fibrosis during the development of scleroderma as well as the effect of α-Klotho in pathogenesis of calcinosis and/or endothelial cell injury and its correlation with severity of disease, this study aimed to evaluate serum ET-1, α-Klotho and 25(OH) vitamin D levels in patients with limited and diffuse scleroderma compared to healthy subjects. In this cross-sectional study, 60 scleroderma patients according to the ACR/EULAR 2013 criteria and 60 age- and sex-matched healthy controls were included. In patients, clinical examination was performed and Medsger severity scale was assessed. Serum ET-1, soluble α-Klotho and 25(OH)D3 levels were measured using ELISA kits. The mean ± SD age of patients and controls was 46.2 ± 9.6 and 47.2 ± 7.0 years, respectively. Compared to healthy controls, serum ET-1 was significantly higher in SSc patients (p = 0.001); whilst serum α-Klotho and 25(OH)D3 were significantly lower in patients (p = 0.001). The most common organs involved in patients were skin, lung, peripheral vascular and gastrointestinal system and the severity of involvement was mainly mild and/or moderate. There were no significant differences in serum ET-1 and α-Klotho levels according to the severity of different organ involvement (p > 0.05). There was no significant correlation between presence or absence of calcinosis and negative or positivity of auto-antibodies with ET-1, α-Klotho and 25(OH)D3 levels. Although our study revealed higher serum ET-1 and lower serum α-Klotho levels in SSc patients compared to healthy controls, there were not any significant correlations between their serum levels with severity of organ involvement.
