Capsaicin Patch Relieves Painful HIV-Associated Neuropathy

NEW YORK (Reuters Health) Jun 23 - In a double-blind randomized study,
a single application of a high-concentration capsaicin skin patch
(NGX-4010) produced a sustained reduction in pain over 3 months in
patients with HIV-associated distal sensory polyneuropathy, the most
common neurologic complication of HIV infection.

"NGX-4010 could provide a promising new treatment for painful HIV
neuropathy," Dr. David M. Simpson, from Mount Sinai School of Medicine
in New York, and colleagues say in the June 10 issue of Neurology.

Following application of a topical anesthetic, 307 patients with
painful HIV-associated distal sensory neuropathy applied a single
NGX-4010 or control patch for 30, 60, or 90 minutes to painful areas
on the feet.

After a transient treatment-related pain increase, the capsaicin patch
resulted in a mean pain reduction of 22.8% during weeks 2 to 12
compared to a mean pain reduction of 10.7% in the control arm (p =
0.0026), the investigators report. "Significant improvement was
apparent by week 2 and continued throughout the controlled 12-week
observation period," they write.

Mean pain reduction in the 30-, 60-, and 90-minute application groups
was 27.7%, 15.9%, and 24.7%, respectively. One-third of NGX-4010-
treated patients reported a 30% or greater drop in pain from baseline
compared with 18% of control patients (p = 0.0092).

Self-limited, mild-to-moderate local skin reactions were common but
"manageable," Dr. Simpson and colleagues report.

"Data from the current study support the use of NGX-4010 both in
combination with systemically acting analgesics and as monotherapy,"
they conclude.

NGX-4010 is being developed by NeurogesX, Inc of San Mateo,
California.

Antioxidant and Iron-Binding Properties of Curcumin, Capsaicin, and
S-
Allylcysteine Reduce Oxidative Stress in Rat Brain Homogenate.

Dairam A, Fogel R, Daya S, Limson JL.
j.limson@@@ru.ac.za.

Research demonstrates that antioxidants and metal
chelators may be of beneficial use in the treatment of
neurodegenerative diseases, such as Alzheimer's disease (AD). This
study investigated the antioxidant and
metal-binding properties of curcumin, capsaicin, and S-allylcysteine,
which are major components found in commonly used dietary spice
ingredients turmeric, chilli, and garlic, respectively.
The DPPH assay demonstrates that these compounds readily scavenge free
radicals.
These compounds significantly curtail iron- (Fe (2+)) and quinolinic
acid (QA)-induced lipid peroxidation and potently scavenge the
superoxide anion generated by 1 mM cyanide in rat brain homogenate.
The ferrozine assay was used to measure the extent of Fe (2+)
chelation, and electrochemistry was employed to measure the Fe (3+)
binding activity of curcumin, capsaicin, and S-allylcysteine. Both
assays demonstrate that these compounds bind Fe (2+) and Fe (3+) and
prevent the redox cycling of iron, suggesting that this may be an
additional method through which these agents reduce Fe (2+)-induced
lipid peroxidation.
This study demonstrates the antioxidant and metal-
binding properties of these spice ingredients, and it is hereby
postulate that these compounds have important implications in the
prevention or treatment of neurodegenerative diseases such as AD.

They are now **targeting** iron as a **SPECIFIC** pain reliever.
This study of a 'patch' containing an iron chelator BEING.. soooo ..
good .. would give credence to my hypothesis.

"Vegetable lecithin applied topically would make a powerful cheap
natural healthy pain relieving anti-ageing skin rejuvenating liver
regenerating heart regenerating skin lightening cholesterol lowering
anti-inflammatory body oil."

http://tinyurl.com/3pnagf

Vegetable oils have been shown to have their 'properties' pass through
the skin into the body when they are applied to the skin ..
slathered .. on.
This would allow the phytic acid / phytate IN the vegetable lecithin
to bind up the iron in the body.
Phytic acid applied to the skin has been shown to raise the phytic
acid levels in the body.
Phytate is the substance drug companies 'hold up to the light' WHEN
they attempt to make iron chelators.

"Does it work as good as phytate?"

They've shown adverse effects with synthetic iron chelators.

ORIGINAL RESEARCH COMMUNICATION

Effects of soy isoflavones and phytate on homocysteine, C-reactive
protein, and iron status in postmenopausal women 1,3

Marian L Kohut and Manju B Reddy
From the Departments of Food Science and Human Nutrition (LNH, HME,
DLA, KLS, and MBR) and of Health and Human Performance (MLK), Iowa
State University, Ames, IA

Background:Soy protein or its components may protect against the
atherosclerotic cardiovascular disease (CVD) risk factors total
homocysteine (tHcy), C-reactive protein (CRP), and excess body iron,
which generally increase with menopause.

Objective:The primary objective of this study was to determine the
independent effect of the soy protein components isoflavones and
phytate on CVD risk factors in postmenopausal women. The secondary
objective was to identify factors [blood lipids, oxidative stress
indexes, serum ferritin, plasma folate, plasma vitamin B-12, and body
mass index (BMI)] contributing to tHcy and CRP concentrations.

Design:In a double-blind, 6-wk study, 55 postmenopausal women aged 47–
72 y were randomly assigned to 1 of 4 soy protein (40 g/d) isolate
treatments: native phytate and native isoflavone (n = 14), native
phytate and low isoflavone (n = 13), low phytate and native isoflavone
(n = 14), or low phytate and low isoflavone (n = 14). We measured iron
indexes, tHcy, CRP, and BMI.

Results:Soy protein with native phytate significantly reduced tHcy (P
= 0.017), transferrin saturation (P = 0.027), and ferritin (P =
0.029), whereas soy protein with native isoflavones had no effect on
any variables. At baseline, BMI was highly correlated with tHcy (r =
0.39, P = 0.003) and CRP (r = 0.55, P < 0.0001), whereas HDL
cholesterol was correlated with CRP (r = –0.30, P = 0.02). Multiple
regression analysis showed that LDL cholesterol and BMI contributed
significantly (R2 = 19.9%, P = 0.003) to the overall variance in
tHcy.

Conclusion:Consuming phytate-rich foods and maintaining a healthy
weight may reduce atherosclerotic CVD risk factors in postmenopausal
women.

Key Words: Postmenopausal women • homocysteine • C-reactive protein •
iron • cardiovascular disease • soy protein • isoflavones • phytate

Chorea is a hyperkinetic movement disorder characterised by excessive
spontaneous movements that are irregularly timed, randomly
distributed
and abrupt. In this article, the authors discuss the causes of
chorea,
particularly Huntington's disease and the genetic syndromes that may
resemble it, including HDL1-3, inherited prion disease,
spinocerebellar ataxias 1, 3 and 17, neuroacanthocytosis,
dentatorubro-
pallidoluysian atrophy (DRPLA), brain iron accumulation disorders,
Wilson's disease, benign hereditary chorea, Friedreich's ataxia and
mitochondrial disease. Acquired causes of chorea include vascular
disease, post-infective autoimmune central nervous system disorders
(PANDAS), drugs, systemic lupus erythematosus, antiphospholipid
syndrome, thyrotoxicosis, AIDS, chorea gravidarum, and polycythaemia
rubra vera. The authors suggest an approach to the clinical
assessment
of chorea, the value of investigations, including genetic tests (for
which they offer a structured framework highlighting the importance
of
prior counselling), and finally briefly discuss symptomatic drug
treatment of chorea.

Trehalose opens new approach to treatment of polyglutamine diseases

Huntington's disease (HD) is a progressive neurodegenerative disorder
caused by a mutation that expands the CAG polyglutamine repeat in the
huntingtin gene beyond normal.
As the formation of insoluble protein aggregates may be linked to the
cellular distortions underlying HD, molecules or proteins that inhibit
their formation have been investigated at RIKEN.
In vitro screening studies showed that various disaccharides can
inhibit polyglutamine-mediated protein aggregation.
The most potent compound, trehalose, stabilized proteins containing
an expanded polyglutamine and decreased formation of aggregates dose-
dependently without inducing any cellular toxicity.
Oral administration (2%) in the R6/2 transgenic mouse model of HD
decreased polyglutamine aggregates in the cerebrum and liver, improved
motor
dysfunction and extended life-span in a dose-dependent manner.
The elevated rate of diabetes in R6/2 mice mimics symptoms observed in
HD
patients.
The examination of fasting blood glucose in R6/2 and wild- type
trehalose-treated (2%) mice were comparable to that of control
mice.
The interaction between disaccharide compounds and polyglutamine-
mediated protein aggregation may provide a novel approach for the
treatment of polyglutamine diseases
(Tanaka, M. et al. Nat Med 2004, 10(2): 148).

PROPERTIES OF TREHALOSE
Trehalose is a disaccharide composed of two glucose molecules bound by
an alpha, alpha-1, 1 linkage.
Since the reducing end of a glucosyl residue is connected with the
other,
trehalose has no reducingpower.
Trehalose is widely distributed in nature.
It is known to be one of the sources of energy in mostliving
organisms and can be found in many organisms, including bacteria,
fungi, insects, plants, and invertebrates.
Mushrooms contain up to 10- 25 % trehalose by dry weight.
Furthermore, trehalose pro-tects organisms against various stresses,
such as dryness, freezing, and osmopressure.
In the case of resurrection plants, which can live in a
dry state, when the water dries up, the plants dry up too.
However,they can successfully revive when placed in water.
The anhydrobitic organisms are able to tolerate the lack of water
owing to
their ability to synthesize large quantities of trehalose, and the
trehalose plays a key role in stabilizing membranes and other
macromolecular assemblies under extreme environmental conditions.
The properties of trehalose are shown in Table 1.
Its relative sweetness is 45 % of sucrose.
Trehalose has high thermostability and a wide pH- stability range.
Therefore, it is one of the most sta-ble saccharides.
When 4 % trehalose solutions with 3.5 to 10 pH were heated at 100 °C
for 24 h, nodegradation of trehalose was observed in any case.
Because of nonreducing sugar, this saccharide does not show Maillard
reaction
with amino compounds such as amino acids or proteins.
Its particular physical features make it an extremely attractive
substance for
industrial applications.
Furthermore, this saccharide shows good sweetness like sucrose, and in
the food industry, this saccharide is used as a sweetener.
