Biophysics and clinical practice for regenerative processes in cirrhosis of the liver/of liver cirrhosis assisted by Delta-S Entropy Variation Systems.

AIM: The therapy in question uses an innovative bioengineering device denoted as ''Delta-S DVD Entropy Variation System''. Previous research indicated regression of cirrhosis as evaluated in its morphofunctional and symptomatological aspects. The aim of the study is to confirm and extend previous experimental observations by enhancing hemodynamic evaluation techniques. In order to clarify scar regression, it was decided to include in the endpoints a quantitative evaluation of portal hypertension called HVPG, which is sensitive to the breakdown of hepatic architecture and the influence of regeneration nodules and therefore the advance of cirrhosis. METHODS: The experimental design consists of a self-controlled study carried out on Child A-B cirrhosis patients with portal hypertension (hepatic venous pressure gradient, HVPG > or = 10 mmHg). Five patients were enrolled, 4 HCV positive, one with autoimmune cirrhosis, all showing extensive symptoms. RESULTS: At the end of the treatment all patients showed a reduction in portal hypertension (mean reduction HVPG = 40.2%, P<0.011), together with an improved ultrasound flowmeter pattern and a sharp decrease or disappearance of the symptoms. No adverse effects were reported. Efficacy on autoimmune cirrhosis was unaffected. CONCLUSIONS: By means of a quantitative analysis of portal hypertension and of functional aspects, this study confirms that the Delta-S DVD system can lead to the regression of the scar component of cirrhosis, promote the regeneration of functioning liver tissue with positive effects on hepatic functionality and prevent symptoms and the risk of varicose vein rupture.

Biophysics of aging and therapeutic interventions by entropy-variation systems.

The cell is thermodynamically an open system and aging is characterized by an increasingly higher structural disorder (increase of entropy) and functional loss. If a variation of negative entropy is introduced by an external source, an anti-clockwise effect leading to regenerative processes and/or increase of the functional reserve supporting regenerative tissue changes is theoretically expected. The achievement of a negative variation of entropy is the main principle of a new technology which implies an exogenous delivery of energy with higher performance than the physiological production. Promising clinical experiences in liver cirrhosis and in long-standing scarring lesions seem to confirm the clinical applicability of the theoretical model.

Cirrhosis progression as a model of accelerated senescence: affecting the biological aging clock by a breakthrough biophysical methodology.

To test new treatment modalities, a pilot study with a novel noninvasive biophysical methodology (Delta-S DVD) that can artificially exert a "decrease of entropy" through the patented electromagnetic-driven delivery of "energy clusters" was designed. This process has been modulated and integrated by the body as a "self" source to support the energy-dependent functional stores, thus modifying reparative into regenerative mechanisms of liver parenchyma. Seven long-standing hepatitis C virus-positive (Child A-B) cirrhosis patients with overt symptoms and portal hypertension and failure or side effects of antiviral drug treatment underwent 40-min sessions of Delta-S DVD daily for six months and were followed up monthly. At the end of the first month, rapid improvement of symptoms and a decrease of portal hypertension were noted. At the end of treatment, all patients showed either a complete (80%) or a partial (20%) regression of fatigue (FISK score), peripheral edema, pruritus, and palmar erythema. As observed, despite having stopped beta-blockers, F1 esophageal varices disappeared (60%), whereas F2 decreased to F1. The Doppler ultrasound aspect of partial (40%) or total (20%) atrophy was either reduced (60%) or reverted to normal (20%), and the respiratory dynamics of the portal vein improved (80%) or normalized (20%), whereas gross scarring nodules disappeared in 40% of cases. These promising data pave the way for an innovative physiopathological approach with extensive clinical applications.

Scrambler therapy.

UNLABELLED: In neuropathies there are complex reactions that modify the homeostatic equilibrium of pain system. In such a context the Scrambler Therapy (ST5) interferes with pain signal transmission, by ''mixing'' a ''non-pain'' information into the nerve fibres. The aim of this study is to evaluate the effectiveness of ST5 in the treatment of neuropathic pain. The ST5 consists of a multiprocessor apparatus able to simulate 5 artificial neurons by the application of surface electrodes on skin pain areas. A total of 226 patients, all suffering from intense drug-resistant neuropathic pain, were recruited for this trial in 2004. INCLUSION CRITERIA: neuropathic pain, very high baseline visual analogue scale (VAS). EXCLUSION CRITERIA: pacemaker users, neurolithic blocks or neurolesive pain control treatment. The treated neuropathic pain syndromes were: failed back surgery syndrome (FBSS), sciatic and lumbar painpost-herpetical (PHN), trigeminal neuralgia, post-surgery nerve lesion neuropathy, pudendal neuropathy, brachial plexus neuropathy, low back pain (LBP), others. The trial programme: 1 to 6 therapy sessions of 5 treatments, each one lasting 30 min. Pain intensity was evaluated using VAS before and after each treatment. The statistical significance of VAS was measured using the paired t-test. The total results show 80.09% of responders (pain relief>50%), 10.18% of partially responders (pain relief from 25% to 49%) and 9.73% of no responders (patients with pain relief<24% or VAS>3). The CONCLUSIONS: is draen that ST5 produced a statistically significant (P<0.0001) pain relief in all treated neuropathies.
