Pain with hernia and treatment with palmitoylethalonamide ( PeaPure)

Heavy neuralgia radiating to the leg is also called sciatica or lumbosacral radiculopathy. Doctors have called this neuritis or neuritis of the sciatic nerve, the Nervus Ischiadicus, for a long time. This old concept has now been given a complete new turn.

Sciatica is caused by mechanic pressure by an intervertebral disc on the beginning of the sciatic nerve, the so-called nerve root within or just outside the vertebral column. Because of that pressure the nerve becomes inflamed and then the pain starts usually quite sudden. Then an inflammation that is maintained by the pressure on that nerve, the hernia, starts.

Pain in Chronic idiopathic axonal polyneuropathy treated with palmitoylethalonamide (PEA)

ciap-pea.jpg There is no evidence from randomised trials of drug therapy for chronic idiopathic axonal polyneuropathy, accrding to a Cochrane review. We quote from that review. Chronic idiopathic axonal polyneuropathy is a not uncommon disorder of the elderly causing very slowly progressive numbness or weakness of the feet and lower legs, and sometimes also the hands. By definition, the cause is not known. No randomised trials of drug treatment for chronic idiopathic axonal polyneuropathy have been conducted. Trials will need sensitive outcome measures and long follow-up periods.

That is why treatments like these need attention, palmitoylethalonamide clearly resulted in decreasing pain in an intractable pain patient suffering from CIAP.

Cancer and neuropathic pain

You are definitely familiar with symptoms as numbing, tingling, or prickling sensatiob,  after you have hit your funny bone, or your foot falls asleep. But for cancer patients, these sensations can be symptoms of either cancer itself, or, more often, a serious side effect of cancer therapy called neuropathy (injury to the nerves).

Management of diabetic painful neuropathy

More than 20 million Americans, representing around 7% of the population, have diagnosed or undiagnosed diabetes, and diabetic polyneuropathy (DPN) is a well known complication and contributes up to nearly 1/3 of all the direct medical costs associated with diabetes.  Around 1/5 of all patients with DPN are suffering from neuropathic pain. How are these patients treated and followed?

Measuring outcome in neuropathic pain trials

neupsig1.jpgDr. Nadine Attal from INSERM, discussed measurements in RCT’s of neuropathic pain and showed that there are great number of pain scales and questionnaires that have been used in clinical trials to assess the efficacy of interventions in neuropathic pain, varying from a simple visual analogue scale (VAS) or the numerical rating scale (NRS) to assess pain intensity to more complex multidimensional scales to assess pain, sleep, depression, quality or life or disability.NRS and VAS remain both the most suitable instruments to assess effects of treatment on pain intensity. Furthermore, clinical global impression of doctors (CGI) and responder rates are recommended for the assessment of overall change of neuropathic pain due to treatment.

Cannabinoids and nerve regeneration or neurogenesis

Most people and neurologist view nerves as ‘copper ropes’ conducting electricity. If the copper rope breaks, the nerve is damaged, and the damage is for the rest of our life. This creates great nihilism for therapeutic innovations. And even more disturbing, patients feel this metaphore is a desription of reality. The message patients often get from their neurologist is: nothing can be done, what is dead remains dead….

The search for the palmitoylethanolamide receptor

pea.jpegPalmitoylethanolamide is hot. It is a body-own compound which seems quite interesting for a number of clinical reasons, and most importantly for its analgesic properties in neuropathic pain. But how does it work? 

The search for the palmitoylethanolamide receptor was the title of a publication in Life Sciences, written by pharmacologists from the Department of Experimental Pharmacology, University of Naples, and the Department of Pharmacology, University of California, Irvine, USA.

Adenosine agonists and neuropathic pain

Adenosine is a neuromodulator that interacs with four adenosine receptors, A(1), A(2A), A(2B) and A(3). Adenosine receptors are new inroads in treating neuropathic pain. Even better, these compounds are inroads to treating gliopathic pain. Gliopathic pain is a new name for the chronic wind-up state of glia and neurons in chronic painstates we see in diabetic neuropathy, herpes zoster and many related painstates.

Palmitoylethanolamide (PEA), an ALIAmide regulating mast cells

montalcini-ngf-1.png

Identification of palmitoylethanolamide (PEA) as regulatory mechanism for the metabolism of mast cells by Nobel Price Laureate Rita Levi Montalcini in 1993, and it’s use as a analgesic and anti-inflammatory compound

Searching for non psychoactive Cannabinoids our clinic identified in 2010 the small molecule palmitoylethanolamide (PEA) as a potent novel and promising analgesic and anti-inflammatory agent. This molecule has been developed based on the work and insights of Rita Levi Montalcini, as an off spin of her work with nerve growth factors.

As PEA, trade names PeaPure and is gaining more and more international recognition as a break through molecule in the treatment of chronic pain and inflammation, it is worth while to shortly analyze how the mast cell modulation concept, palmitoylethanolamide and the ALIA concepts came into existence.

CIDP associated with MGUS treated with palmitoylethanolamide and low dose naltrexone

mgus.jpg MGUS is a very rare peripheral neuropathy, usually late-onset in terms of the sufferer’s age. It is one of the chronic demyelinating polyneuropathy group, that are mixed motor-sensory nerve affected and symmetrical in the damage caused. Paraproteinaemic Demyelinating Neuropathy may be known by a variety of other titles: MGUS-associated neuropathy, polyneuropathy, Paraprotein-associated demyelinating neuropathy, Paraprotein associated neuropathy/polyneuropathy, CIDP associated with a paraprotein, CIDP associated with MGUS, paraprotein-related or associated demyelinating neuropathy, demyelinating paraproteinaemic neuropathy, MGUS polyneuropathy and Peripheral Neuropathy associated with benign monoclonal gammopathy. We treated the pain, which was refractory to classical analgesics, with a combination of palmitoylethanolamide and low dose naltrexone, and a tiny amount of pregabaline (25 mg and 50 mg) and could reduce the pain for around 50%.

Multimodal therapy in neuropathic pain: 2 is more than 1!

The famous Dutch surgeon Noordenbos wrote in 1959: "One-one synaptic transmission must be the exception rather than the rule in the nervous system. Any nerve cell located in the anterior horn. . . could hardly be expected to synapse at higher level with one such similar cell only. It will probably send ramifications to many other locations, and in turn be acted upon by the ramifications of many other cells. . . Far from being a continuous chain of short neurons, these fibres must constitute links in an extremely complicated nerve net in which, within limits, everything synapses more or less with everything else." It is clear that half a century later our therapy of pain is based on these deep insights of Noordenbos, and multimodal therapy is now the hallmark of how to treat neuropathic pain. This is because it is difficult to treat neuropathic pain with one drug only. In our centre we nearly always prescribe two or more oral drugs and mostly also topical creams and supplements together to get the patients out of the red zone of discomfort.

Ziconotide in chronic pain requiring intraspinal analgesia: orphan drug

Ziconotide is a man-made equivalent of a molecule composed of a 25-amino acid chain, which is found in the venom of a fish-eating marine snail, Conus magus. Ziconotide blocks the action of specific molecules found in nerve tissue, called N-type voltage-sensitive calcium channels. These molecules play an important role in chronic pain. Ziconotide is expected to decrease pain by blocking the function of these molecules.
