Does group-based high-intensity aerobic interval training improve the inflammatory status in patients with chronic heart failure?

BACKGROUND: Chronic heart failure (CHF) is a multifaceted syndrome associated with endothelial dysfunction and increased inflammation. Despite the existing controversies regarding the appropriate training modality, it is widely accepted that supervised cardiac rehabilitation (CR) interventions lead to proinflammatory biomarkers reduction and cellular adhesion molecules in patients with CHF. AIM: The aim of the study was to quantify the effects of 12-week group-based high-intensity aerobic interval training (HIAIT)/modified group-based HIAIT intervention (m-Ullevaal) vs. moderate continuous training (MICT) on serum levels of proinflammatory biomarkers. DESIGN: Single-blind, two-arm, prospective randomized controlled trial conducted on CHF outpatients performing group-based CR interventions throughout a 12-week period. SETTING: The setting of the study was the Medical Center of Outpatient Rehabilitation and Sports Medicine, Plovdiv, Bulgaria. POPULATION: The population included a total of 120 outpatients of both genders, mean age of 63.73±6.68 years, with stable CHF (NYHA classes II to IIIB, were randomly assigned to HIAIT/ m-Ullevaal (N.=60) or to MICT (N.=60) group. METHODS: Functional exercise capacity (FEC) of the eligible subjects was evaluated through 6-minute walk test (6MWT) and peak oxygen uptake. Blood samples were drawn at baseline, after 12 weeks follow-up for analyses of C-reactive protein (CRP), tumor necrosis factor-α (TNFα) and cellular adhesion molecules (CAM). RESULTS: Significant decreases in the serum levels of CRP (P=0.029), TNF-α (P=0.036), and vascular cell adhesion molecule-1 (VCAM-1) (P=0.040), were observed after 48 training sessions in the group-based HIAIT/m-Ullevaal intervention, except for intercellular adhesion molecule-1 (ICAM-1), which was higher in the MICT (P=0.034). FEC was significantly inversely related to CRP (r=-0.72, P<0.05), and the levels of VCAM-1 (r=-0.68, P<0.05). CONCLUSIONS: Both group-based CR interventions (HIAIT/m-Ullevaal and MICT) significantly reduced the serum levels of CRP, TNF- α, ICAM-1 and VCAM in patients with CHF. However, selected proinflammatory biomarkers changes and CAMs favorably decreased in the group-based HIAIT/m-Ullevaal intervention. The responses on serum levels of proinflammatory biomarkers and CAMs are dependent upon the type, intensity, and CR intervention duration. CLINICAL REHABILITATION IMPACT: The group-based high-intensity aerobic interval training reduces significantly the proinflammatory biomarkers and cellular adhesion molecules in patients with chronic heart failure.

[Mesotherapy as a treatment of pain and disability in patients affected by neck pain in spondylartrosis]. / La mesoterapia come trattamento del dolore e della disabilità in pazienti affetti da cervicalgia in spondilartrosi.

Mesotherapy is a technique that treats locoregional pain with intradermal injection of a drug in the affected area. Its short-term efficacy was observed in patients with low back pain using both normal saline solution, if there were contraindications to drugs' use, or a cocktail of drugs (normal saline solution, lidocaine hydrochloride, and lysine acetylsalicylate), whereas only the latter provided benefit for up to three months after treatment. The aim of this study was to measure the effects of mesotherapy in patients affected by neck pain in spondylarthrosis, a common pathology in rehabilitation, associated with significant disability and increased health expenditure. One hundred patients participated in the study, of whom 50 (mean age 66.9 years) were treated with mesotherapy with a cocktail of drugs and 50 (mean age 64.7 years) with normal saline solution. Pain and disability were measured at different times (i.e. before treatment, at the end of five weeks of treatment, four weeks and 12 weeks after treatment), by using different pain scales, including a visual analogue scale, the short-form McGill pain questionnaire, the Present Pain Intensity scale and the Neck Disability Index. Mesotherapy with either normal saline solution or with a cocktail of drugs were both found to be effective in the short term in reducing pain and disability. However, only patients treated with a cocktail of drugs showed improvement at three months following treatment.

[Short-term and medium-term efficacy of mesotherapy in patients with lower back pain due to spondyloarthrosis]. / Efficacia della mesoterapia a breve e medio termine in pazienti affetti da lombalgia muscolotensiva da spondilartrosi.

Mesotherapy is an intradermal treatment for patients with local pain. The literature describes the efficacy of mesotherapy in the treatment of musculoskeletal disorders measuring a reduction of analgesic drug intake and of healthcare spending. The aim of this study was to measure the effects of mesotherapy on pain and disability in patients with low back pain due to spondyloarthrosis.

Efficacy of mesotherapy using drugs versus normal saline solution in chronic spinal pain: a retrospective study.

Mesotherapy, or intradermal therapy, is a therapeutic approach that is gaining popularity, but there is still a significant lack of information on its mechanisms of action or the pharmacokinetics of the therapeutic regimens. This retrospective study on 220 records compared the short-term and long-term effects of mesotherapy using a mixture of drugs versus normal saline solution in the treatment of patients with chronic spinal pain (CSP). At the end of treatment, outcome measures showed a significant improvement (P<0.003) in both groups, which persisted at the follow-up assessments. At 12 weeks of follow-up, the improvement was significantly greater in patients treated with the drug cocktail than with the saline solution (P<0.05). Mesotherapy was effective in patients affected by CSP, with high patient satisfaction reported irrespective of the agent used. Considering the risks and costs of drugs, normal saline solution appears to be the best agent in cost-benefit terms for treating localized pain by mesotherapy in CSP.

The efficacy and safety of a combination of glucosamine hydrochloride, chondroitin sulfate and bio-curcumin with exercise in the treatment of knee osteoarthritis: a randomized, double-blind, placebo-controlled study.

BACKGROUND: Knee osteoarthritis (OA) conservative treatment aims to delay cartilage degeneration; chondroprotective agents are a valid approach in this sense. A commercially available dietary supplement, CartiJoint Forte, containing glucosamine hydrochloride (GH), chondroitin sulfate (CS) and Bio-Curcumin BCM-95®, was used in this trial. AIM: The aim of this study was to assess efficacy and safety of CartiJoint Forte combined with physical therapy in treating subjects with knee OA. DESIGN: A multicenter, prospective, randomized, double blind, placebo-controlled clinical trial. SETTING: Outpatients referred to the Rehabilitation Departments of two University Hospitals. POPULATION: Fifty-three patients were randomly assigned to an experimental group (N=26) or a control group (N.=27). Experimental subjects received two tablets of CartiJoint Forte each day for 8 weeks, while those in the control group were provided with a placebo. Three subjects dropped out during the course of the study. METHODS: The two groups both received 20 sessions of physical therapy during the course of the trial. Primary outcome was pain intensity, measured both at motion and at rest, using the Visual Analogue Scale (VAS). A secondary outcome was an assessment of knee function by Western Ontario and McMaster Universities Arthritis Index and Lequesne Index, knee ROM, and two inflammation markers (C-reactive protein and erythrocyte sedimentation rate). Each assessment was carried out at baseline (T0), at 8 weeks (T1) and at 12 weeks (T2). RESULTS: VAS at rest was found to be reduced between T0 and T1, as well as between T0 and T2 (F=13.712; P=0.0001), with no differences between groups (F=1.724; P=0.191). VAS at motion revealed a significant "group × time-check" interaction (F=2.491; P=0.032), with increasing effect of time on VAS reduction (F=17.748; P=0.0001). This was most pronounced in the experimental group at 8 weeks (F=3.437; P=0.045). The Lequesne Index showed reductions at T1 and T2 compared to T0 (F=9.535; P=0.0001), along with group effect, since the experimental group presented a lower score at T2 (F=7.091; P=0.009). No significant changes were found in the knee ROM and inflammation markers. CONCLUSION: CartiJoint Forte, added to physical therapy, may ameliorate pain and help to improve algofunctional score in knee OA patients. CLINICAL REHABILITATION IMPACT: Treatment of knee OA with curcuminoids plus glycosaminoglycans, added to physical therapy, improves VAS at motion and Lequesne Index scores.

CB1 receptor affects cortical plasticity and response to physiotherapy in multiple sclerosis.

OBJECTIVES: Therapeutic effects of physical therapy in neurologic disorders mostly rely on the promotion of use-dependent synaptic plasticity in damaged neuronal circuits. Genetic differences affecting the efficiency of synaptic plasticity mechanisms could explain why some patients do not respond adequately to the treatment. It is known that physical exercise activates the endocannabinoid system and that stimulation of cannabinoid CB1 receptors (CB1Rs) promotes synaptic plasticity in both rodents and humans. We thus tested whether CB1R genetic variants affect responsiveness to exercise therapy. METHODS: We evaluated the effect of a genetic variant of the CB1R associated with reduced receptor expression (patients with long AAT trinucleotide short tandem repeats in the CNR1 gene) on long-term potentiation (LTP)-like cortical plasticity induced by transcranial magnetic theta burst stimulation (TBS) of the motor cortex and, in parallel, on clinical response to exercise therapy in patients with multiple sclerosis. RESULTS: We found that patients with long AAT CNR1 repeats do not express TBS-induced LTP-like cortical plasticity and show poor clinical benefit after exercise therapy. CONCLUSIONS: Our results provide the first evidence that genetic differences within the CB1R may influence clinical responses to exercise therapy, and they strengthen the hypothesis that CB1Rs are involved in the regulation of synaptic plasticity and in the control of spasticity in humans. This information might be of great relevance for patient stratification and personalized rehabilitation treatment programs.

Transcranial magnetic stimulation primes the effects of exercise therapy in multiple sclerosis.

Exercise therapy (ET) can be beneficial in disabled multiple sclerosis (MS) patients. Intermittent transcranial magnetic theta burst stimulation (iTBS) induces long-term excitability changes of the cerebral cortex and may ameliorate spasticity in MS. We investigated whether the combination of iTBS and a program of ET can improve motor disability in MS patients. In a double-blind, sham-controlled trial, 30 participants were randomized to three different interventions: iTBS plus ET, sham stimulation plus ET, and iTBS alone. Before and after 2 weeks of treatment, measures of spasticity through the modified Ashworth scale (MAS) and the 88 items Multiple Sclerosis Spasticity Score questionnaire (MSSS-88), fatigue through the Fatigue Severity Scale (FSS), daily living activities (ADL) through the Barthel index and health-related quality of life (HRQoL) through the 54 items Multiple Sclerosis Quality of life inventory (MSQoL-54) were collected. iTBS plus ET reduced MAS, MSSS-88, FSS scores, while in the Barthel index and MSQoL-54, physical composite scores were increased. iTBS alone caused a reduction of the MAS score, while none of the measured scales showed significant changes after sham iTBS plus ET. iTBS associated with ET is a promising tool for motor rehabilitation of MS patients.
