          Abstract

          We conducted an 8-week, open, randomized controlled clinical trial on 141 subjects affected by neuropathic pain to investigate the role of an adjunctive therapy added to the administration of dexibuprofen (400 mg twice a day) and based on a multi-ingredient formula (Lipicur), consisting of lipoic acid plus curcumin phytosome and piperine, in patients with a diagnosis of lumbar sciatica, lumbar disk herniation, and/or lumbar canal stenosis (96 subjects), or with carpal tunnel syndrome (45 subjects). A total of 135 participants completed the study. Treatment with the multi-ingredient formula (Lipicur) reduced neuropathic pain by more than 66% in both conditions (subjects with lumbar sciatica and with carpal tunnel syndrome), and these reductions were statistically significant. Moreover, the treatment reduced dexibuprofen use by about 40%. An add-on therapy with only lipoic acid has not shown any significant results. On the basis of its safety and efficacy, Lipicur could be considered an effective complementary therapy to be added to conventional treatments to achieve better efficacy in reducing neuropathic pain.

          The genetic contribution to carpal tunnel syndrome in women: a twin study.

          To assess the relative genetic and environmental contribution to carpal tunnel syndrome (CTS) using a classic twin study of monozygotic (MZ) and dizygotic (DZ) twins. The study group comprised unselected female twin pairs, between 20 and 80 years of age, from the St Thomas' UK Adult Twin Registry. Individuals completed a questionnaire that included details on potential risk factors for CTS. The diagnosis of CTS was made using a standardized hand pain diagram and validated criteria. The genetic contribution to CTS was assessed using variance component and regression methods, the heritability was adjusted for environmental confounders. The role of individual risk factors was assessed by a nested case-control study. An overall prevalence of 14.2% for CTS was found in a population of 4,488 females, comprising 867 MZ and 970 DZ twin pairs, and 814 singletons. The concordance for CTS was significantly higher in MZ compared with DZ twins (case-wise concordance values of 0.35 and 0.24 respectively, with a significantly increased MZ:DZ ratio of 1.48; P = 0.03). Modeling produced a heritability estimate of 0.46 (95% CI 0.34-0.58) that was essentially unchanged after adjustment for environmental risk factors including age, body mass index, physical activities, and hormonal/reproductive factors. No major influence of any individual risk factor was seen in the case-control analysis of 520 cases and 3,154 controls, apart from a modest association with menopausal status with an increased risk of 1.53 and 1.43 in the peri and postmenopausal groups. There was no overall effect of age or body mass index. This is the first study to explore the genetic component of CTS. Our data show that up to half of the liability to CTS in women is genetically determined, and this appears to be the single strongest risk factor, with only minor contributions from known environmental factors. Further studies should focus on genetic mechanisms that may lead to tests for susceptibility and detection of those at risk of developing CTS.

            Comparative evaluation of the pain-relieving properties of a lecithinized formulation of curcumin (Meriva®), nimesulide, and acetaminophen

            In addition to its anti-inflammatory activity, Meriva®, a proprietary lecithin formulation of curcumin, has been anecdotally reported to decrease acute pain in patients with various chronic diseases. Given that curcumin can desensitize transient receptor potential A1, a nociceptor seemingly also mediating the analgesic effect of acetaminophen, as well as inhibiting and downregulating the expression of cyclo-oxygenase 2, the selective target of nimesulide, a nonsteroidal anti-inflammatory agent, we carried out a pilot comparative study of the acute pain-relieving properties of these three agents. At a dose of 2 g (corresponding to 400 mg of curcumin), Meriva showed clear analgesic activity, comparable with that of a standard dose (1 g) of acetaminophen, but lower than that of a therapeutic (100 mg) dose of nimesulide. The analgesic activity of lower (1.5 g) doses of Meriva was less satisfactory, and the onset of activity was longer than that of nimesulide for both doses. On the other hand, gastric tolerability was significantly better than that of nimesulide and comparable with that of acetaminophen. Taken together, our results show that the preclinical analgesic properties of curcumin have clinical relevance, at least at a dose of 2 g as the Meriva formulation. While this dose is significantly higher than that used to relieve chronic inflammatory conditions (1–1.2 g/day), its pain-relieving activity could benefit from the general downregulation of the inflammatory response induced by curcumin, considering that the transient receptor potential channel-mediated mechanisms of analgesia are magnified by attenuation of inflammation. In patients on treatment with Meriva, this would also translate into better control of acute pain, providing a rationale for the analgesic properties associated with this curcumin formulation.

              Quality of life assessment in a living donor kidney transplantation program: evaluation of recipients and donors.

              Quality of life (QOL) in donors before and after living kidney donor transplantation (LKDT) has been an important concern. Investigation of these issues in related recipients is not as common. Since 2002, a protocol of psychosocial evaluation for donors and recipients was included in the living kidney donation program. We sought to evaluate QOL in donors and recipients, before and after transplantation, and to compare the 2 groups.
