Thermal water of Vetriolo, Trentino, inhibits the negative effect of interleukin-1β on nitric oxide production and apoptosis in human osteoarthritic chondrocyte.

The thermal water of Vetriolo in Trentino, Italy (VW) has been known over 150 years for its therapeutic properties in the treatment of osteoarthritis (OA). This is a highly mineralized water, strongly acidic sulfate, rich in calcium, magnesium and iron and used for balneotherapy after dilution. The aim of our study was to investigate the possible in vitro effects of the VW in human OA chondrocytes cultivated in the presence or in the absence of Interleukin-1 beta (IL-1beta). OA chondrocytes were cultivated in Deionized Water (DW) (DW-DMEM, controls), or in one of three different VW-DMEM media, in which DW had been totally (100 percent) or in part (25 or 50 percent) substituted with VW. All samples were analyzed before and after treatment with IL-1beta at a concentration of 5 ng/ml. After 48 h, we evaluated the cell viability, the release of nitric oxide (NO) in culture medium, the inducible nitric oxide synthase (iNOS) expression, and the percentage of apoptosis and necrosis. Finally, we carried out a morphological assessment using a transmission electron microscope (TEM). Our data showed that VW alone at 25 or 50 percent concentration did not affect the viability of cultured OA chondrocytes, and determined a significant survival recovery rate in cultures stimulated with IL-1beta. On the contrary, the VW alone at 100 percent of concentration reduced, in a significant (P less than 0.05) manner, the cells viability. NO levels were low both in DW-DMEM cultures and in those reconstituted with 25 or 50 percent of VW, and were significantly (P less than 0.05) increased in cultures with 100 percent of VW. VW at 25 or 50 percent concentration significantly (P less than 0.001) reduced the NO production induced by IL-1beta. The data of the NO levels were confirmed by the immunocytochemistry assay for iNOS. Our experiments confirmed the pro-apoptotic effect of IL-1beta and demonstrated a protective effect of VW at 25 or 50 percent concentration. These findings were confirmed by TEM. In conclusion, our study demonstrated that VW alone at 25 or 50 percent concentration modifies neither morphology nor NO production and neither iNOS expression nor apoptosis, but it inhibits the negative effects of IL-1beta in chondrocytes cultures.

Phytothermotherapy: a possible complementary therapy for fibromyalgia patients.

OBJECTIVE: It is a traditional practice in the Alpine region of Trentino and Alto Adige (Italy) to use phytothermotherapeutic treatment with fermenting grass ("hay baths") for rheumatic diseases. However, despite its long history and popularity, a clinical validation of the efficacy and tolerability of the treatment has yet to be found in current literature. Fibromyalgia syndrome (FMS) is characterised by generalised musculoskeletal pain, high tender point counts, sleep disturbance, fatigue, headaches, irritable bowel syndrome, frequent psychological distress and depressed mood. There is no standard therapy regime for FMS and the variety of medical treatments used have given limited benefits. The aim of this study was to assess the efficacy and tolerability of a cycle of phytothermotherapy through a single-blind, controlled, randomised trial, in patients with primary FMS. METHODS: Fifty-six patients with primary FMS according to the ACR criteria were randomly allocated to two groups: 30 were submitted to phytothermotherapy at the thermal resort of Garniga Terme (Trento, Italy) and the other 26 were considered as controls. All patients were evaluated by FIQ, Tender Points Count, HAQ and AIMS1 at baseline, after 10 days, then after 12 and 24 weeks. RESULTS: Patients submitted to phytothermotherapy showed visible and significant improvement of all evaluation parameters at the end of the treatment, which persisted during the follow-up period. No significant difference was found in the control group. Regarding the tolerability, none of the patients presented side effects. CONCLUSIONS: Our results suggest the efficacy and the tolerability of phytothermotherapy in patients with primary FMS.

[Phytothermotherapy with fermenting alpine grass in knee osteoarthritis: mid-long term results]. / Fitobalneoterapia con bagni nell'erba di montagna in fermentazione nella gonartrosi: risultati a medio-lungo termine.

This is an observational study of the mid-long-term results of a single course of phytothermotherapy with grass baths (group A, 54 patients), of a course of usual medical care (group B, 58 patients) and of a course of physiokinesistherapy (FKT, group C, 30 patients) in knee osteoarthritis. For each group of consecutively treated patients we evaluated the Lequesne algo-functional Index, the drug consumption, the frequency of the patient-physician contacts and laboratory or radiological examinations after 10-15 days of treatment and at 3, 6, 9 and 12 months with blind telephonic follow-up. The mean Lequesne-score at basal time was 7.5+/-3.3, 11.9+/-5.3 and 11.0+/-2.7 in group A, B and C respectively. In each group this score diminished at the end of the treatment (p<0.001). At 3, 6, 9 and 12 months the score remained lower than at basal time in group A (p<0.001) and group B (p<0.01), but not in group C. Drug consumption, patient-physician contacts and lab examinations were 5 times lower in group A than in group B and group C at basal time and throughout the follow-up. The study underlines the mid-long term efficacy of grass baths on both pain and functionality in knee osteoarthritis; this effect, compared to basal values, was even more evident at 3 and 6 months than that of usual medical care. FKT shows improvement only at the end of the treatment, but not long-lastingly.
