Efficacy of Ketamine in Bipolar Depression: Systematic Review and Meta-analysis.

Parsaik AK1, Singh B, Khosh-Chashm D, Mascarenhas SS.

.

OBJECTIVE: To consolidate the evidence from the literature to evaluate the role of ketamine in the treatment of bipolar depression.

.

METHODS: Major databases, including MEDLINE, EMBASE, Cochrane, and Scopus, were searched through October 2014, for studies reporting the role of ketamine in the treatment of bipolar depression. Only randomized controlled trials were included in the meta-analysis. We calculated standardized mean differences (SMDs) with SE for each study included in the meta-analysis. A random effect model was used to calculate the pooled SMDs. Heterogeneity was assessed using the Cochran Q test and I statistic.

.

RESULTS: Of the 721 articles that were screened, 5 studies that enrolled a total of 125 subjects with bipolar depression (mean age, 44.6+/-4.3y and 65.6% females) were included in the systematic review; 3 randomized controlled trials (69 subjects) were included in the meta-analysis. The meta-analysis showed significant improvement in depression among patients receiving a single dose of intravenous ketamine compared with those who received placebo (SMD=-1.01; 95% confidence interval, -1.37, -0.66; P<0.0001). The maximum improvement was observed 40 minutes after the ketamine infusion. No heterogeneity was observed between the studies (Cochran Q test P=0.38, I=0%). The 2 studies that were excluded from the meta-analysis also showed significant improvement in depression after ketamine therapy. Individual studies also reported improvement in anhedonia and suicidal ideation after ketamine therapy. None of the subjects had serious side effects, and the side effects were similar between the ketamine and placebo groups.

.

CONCLUSIONS: This study suggests that ketamine is effective in treatment-resistant bipolar depression and may reduce suicidal ideation and anhedonia.

Ketamine Prescribed Since 1994 – My Experience


.

.

.

Ketamine offers an opportunity for normal life unmatched by any medication I know of when given off-label for chronic treatment of intractable pain, treatment resistant depression, bipolar depression, juvenile bipolar disorder. It is one of the safest medications I have prescribed in 41 years of medicine. I have never seen anything more effective – it is not a cure, but remission is highly possible. Please refer to peer reviewed references since 2009 on this website on ketamine and depression or pain. Read elsewhere about street drugs, junkies, addicts and media headlines.

.

Never Ketamine Alone

.

Ketamine is short acting no matter how it is given.

.

I never prescribe ketamine by itself – a fools errand; the religion of ketamine is like the religion of opioids. Decades of intractable conditions and chronic neuroinflammation require more than one short acting drug and usually require a multi-disciplinary approach. I work with psychologists or psychiatrists and other specialists when indicated.

.

1994 – I first prescribed IV when teaching cancer pain at MD Anderson Cancer Center.

.

2001 – prescribed for outpatient care of chronic intractable pain

.

2011 – prescribed for treatment resistant depression, bipolar depressed, juvenile bipolar/fear of harm phenotype often diagnosed as oppositional defiant disorder.

.
2009 – writing about ketamine, neuro-inflammation and glial modulators on this site, with classic references to publications from the foremost peer reviewed journals, including low dose naltrexone, oxytocin.

.

Dosing

.
Depression, Bipolar Disorder, Juvenile Bipolar/FOH, treatment resistant – may need a dose only twice daily or every 3 days. The dose and frequency of use cannot be predicted – it is idiosyncratic – look up that word.

.

Intractable pain – dosing and frequency of medications is very different than for depression.

.
My work with these medications, these glial modulators, is too extensive to annotate on these pages. This website since April 2009 has references for context and guidance with active links to peer reviewed publications. Example:

.
Clinical experience using intranasal ketamine in the treatment of pediatric bipolar disorder/fear of harm phenotype. D Papolos et al, J Affect Disord. 2013 May;147(1-3):431-6.

.

RESULTS:

Ketamine administration was associated with a substantial reduction in measures of mania, fear of harm and aggression. Significant improvement was observed in mood, anxiety and behavioral symptoms, attention/executive functions, insomnia, parasomnias and sleep inertia. Treatment was generally well-tolerated.

.

CONCLUSIONS:

Intranasal ketamine administration in treatment-resistant youth with BD-FOH produced marked improvement in all symptomatic dimensions. A rapid, substantial therapeutic response, with only minimal side effects was observed. Formal clinical trials to assess safety and efficacy are warranted.

mTOR-Dependent Synapse Formation Underlies the Rapid Antidepressant Effects of NMDA Antagonists. R Duman et al, August 2010, Science, Science 2010 Aug: Vol. 329, Issue 5994, pp. 959- 964. [this article free with registration]
.

ABSTRACT:

.

We observed that ketamine rapidly activated the mammalian target of rapamycin (mTOR) pathway, leading to increased synaptic signaling proteins and increased number and function of new spine synapses in the prefrontal cortex of rats. Moreover, blockade of mTOR signaling completely blocked ketamine induction of synaptogenesis and behavioral responses in models of depression. Our results demonstrate that these effects of ketamine are opposite to the synaptic deficits that result from exposure to stress and could contribute to the fast antidepressant actions of ketamine.

.

.

“The resulting protein synthesis and neuronal alterations in the medial prefrontal cortex are the opposite of those produced by chronic stress….”

John C. Liebeskind, 1935 – 1997, distinguished scholar and researcher, past president of the American Pain Society, had the radical idea that pain can affect your health.

 

Research decades ago by an Israeli team at UCLA and others had shown “that pain can accelerate the growth of tumors and increase mortality after tumor challenge.” Decades ago Professor Liebeskind lectured all over the country: Pain kills.

 

He wrote an editorial in 1991, summarizing a life’s work:

 

“Pain and stress can inhibit immune function.”

 

 

Quoting John Bonica, the father of modern pain management, he wrote:

 

“Bonica has long argued that the term ‘chronic benign pain’ (used in distinction to pain associated with cancer) is seriously misleading.  Chronic pain is never benign, he contends; “it is a ‘malefic force’ that can devastate its victims’ lives and even lead to suicide.”

 

 

Liebeskind continues, “It appears that the dictum ‘pain does not kill,’ sometimes invoked to justify ignoring pain complaints, may be dangerously wrong.”

 

Pain mediates immune function

 

Importantly

 

  Opioids mediate the suppressive effect of stress on natural killer cells,

 

 published in 1984, immune system.

 

Alcohol increases tumor progression, 1992, immune system.

 

It used to be news.

He did not live to see change.

 

People just want to go on doing what they’re doing.

They want business as usual.

 

 

After 1991, we saw the great discoveries of neuroinflammation, pioneered by Linda Watkins, PhD, the early understanding of the innate immune system, its involvement in chronic pain and depression, and a few weeks ago, a British team showed neuroinflammation in teens with early signs of schizophrenia and DNA markers.

 

 

Major Depression has the same neuro-inflammation found in chronic pain, often responding to same medications, in particular glial modulators – immune modulators. Now, perhaps early schizophrenia will respond to glial modulators, reducing inflammation seen on scan in teens, before they become homeless and burned out by antipsychotic drugs

 

Inflammation out of control destroys neurons

 

Fire on the brain

 

 

We must be the change we wish to see

 

It’s not just the Bern. It’s been starting. Forces are finally coming together. We want change. It’s been too much. Too long.

 

We won’t take it anymore.

 

I figure if I tell you about it, you might just mention it to someone to pass it on. That is all. One small action may lead to change. Activate inputs to the NIH strategic plan.

In the 1970’s, Professor Liebeskind and an Israeli team at UCLA injected cancer cells to two groups of rats that had sham surgery. Cancer spread much faster and killed far sooner in the group with poor treatment of surgical pain.

He lectured all over the country

 

Forty five years ago

 

 

I’m gonna be dead before I see this country do anything but unaffordable opioids and the magical ineffective trio of gabapentin, Lyrica, Cymbalta to treat chronic pain. The devastating, blind, nationwide emphasis does nothing to address the cause: inflammation, the innate immune system gone wild.

Untreated pain suppresses the hormone systems too.

 

Untreated depression – same inflammation kills lives.

People are dying from prescription opioids and those who need them find they don’t work well enough. Prescriptions opioid costs must be a huge fraction of the medical costs in the United States GDP. You are required  to see a doctor every single month each year, often lifelong, just for one opioid, 12 months a year x 30 years x tens of millions of people and increasing – a growth industry. Not even counting $600 a day for the opioid, what the cost of monthly visits for 30 years? Not counting the army of DEA, FDA, CDC agents watching the opioids like a hawk. We all have to be sharp, addiction is growing. Addiction aside, deaths from prescription opioids are shaking up the CDC forcing urgent change this coming month.

We are at a turning point and we will fail to catch the sail that’s coming fast to carry all research money in their shiny big stem cell direction. They never look back.

 

 

There is so many medications we can use today, FDA approved drugs that can be re-purposed and applied to recent cutting edge science. Someone must pay to do the work to study this.

 

 

Re-purpose old drugs

 

 

Stanford just showed a popular generic drug improved recovery of stroke paralysis in mice to begin at 3 days rather than 30. Old drug, new purpose, of course more years of testing to confirm in humans. Brilliant team applying new science.

Hundreds of old drugs, already approved, could be involved in mechanisms we have recently learned about. Speak up or money will go to shiny new stem cells. None for chronic pain or major depression. No company will find this profitable – it must be funded by NIH. A popular generic sleeping pill can bring astonishing return from stroke paralysis.

Analgesic Response to Ketamine Linked to Circulating microRNA in Complex Regional Pain Syndrome


.

.

Analgesic Response to Intravenous Ketamine

Is Linked to a Circulating microRNA Signature

in Female Patients

With Complex Regional Pain Syndrome

.

.


The ability to measure Micro RNS’s (miRNA) in blood looks like it may become an important tool someday once it is available for the clinic. It could be used to predict if your condition will respond to various medications.

.

MicroRNAs are emerging as important modulators of various psychiatric (schizophrenia, bipolar disorder) and neurological conditions including pain, epilepsy, cognitive dysfunction, neuronal development, structure and function. “MicroRNAs are small, non-coding RNAs that act as post-transcriptional regulators of gene expression.  miRNA’s can be affected by morphine and affected by other drugs. It is hoped that complex clinical phenotypes may be profiled in assays of peripheral blood and may predict response to treatment such as in this study. Ketamine is given for selected patients that have failed to respond to standard treatment.

.

This research was published in Pain, June 2015, by Professor Schwartzman’s group at Drexel University. Seven of his patients with Complex Regional Pain Syndrome were ketamine responders and 6 were poor responders. They note that, “Although [ketamine] treatment is generally effective, approximately 30% of patients have an inadequate response to ketamine.”

.

“Stability in circulation and dysregulation in disease state are 2 features making extracellular miRNAs useful candidates for biomarker discovery. Alterations in miRNA profiles have been reported for rheumatoid arthritis and systemic lupus erythematosus as well as for painful conditions such as irritable bowel syndrome, chronic bladder syndrome, endometriosis, and migraine. Cerebrospinal fluid from patients with fibromyalgia showed differential expression of 9 miRNAs.”

.

Quoting directly from the article:

.

Highlights

.
•We studied ketamine treatment–induced miRNA alterations in blood from patients with CRPS.
•Differential miRNA expression was observed in whole blood before and after treatment.
•Before therapy, 33 miRNAs differed between responders and poor responders.
•Lower pretreatment levels of miR-548d-5p may contribute to higher UDP-GT activity.
•Circulating miRNAs can be potential biomarkers in predicting treatment response.

.

From the Abstract

.

Investigation of the mechanistic significance of hsa-miR-548d-5p downregulation in poor responders showed that this miRNA can downregulate UDP-glucuronosyltransferase UGT1A1 mRNA. Poor responders had a higher conjugated/unconjugated bilirubin ratio, indicating increased UGT1A1 activity. We propose that lower pretreatment levels of miR-548d-5p may result in higher UDP-GT activity, leading to higher levels of inactive glucuronide conjugates, thereby minimizing the therapeutic efficacy of ketamine in poor responders.

.

Perspective

.
This study suggests the usefulness of circulating miRNAs as potential biomarkers. Assessing miRNA signatures before and after treatment demonstrated miRNA alterations from therapy; differences in miRNA signature in responders and poor responders before therapy indicate prognostic value. Mechanistic studies on altered miRNAs can provide new insights on disease.

 

.

 

From the Discussion

.

Ketamine is also considered to be the prototype for a new generation of glutamate- based antidepressants that can alleviate depression within hours of treatment. Several biological measures have been explored to characterize treatment response and to gain insight into mechanisms underlying the rapid antidepressant effects of ketamine. A plasma metabolomics study in patients with bipolar depression suggested that the basal mitochondrial b-oxidation of fatty acids differed between responders and nonresponders to ketamine. Other studies have shown differences in baseline plasma concentrations of D-serine, serum levels of interleukin 6, and plasma levels of Shank3, a postsynaptic density protein involved in NMDA receptor tethering and dendritic spine rearrangement.

.

.

Differences in the ability to metabolize ketamine because of interindividual differences and pharmacogenetic factors have been proposed to contribute to the varied responses to ketamine therapy and its clinical outcome. Similar conclusions have been drawn for patients with depression; plasma from patients with treatment- resistant bipolar depression who had undergone a single 40-minute infusion of a subanesthetic dose of ketamine showed that although NK is an initial metabolite, it is not the major circulating metabolite. This again suggests that other downstream metabolites of ketamine may play a role in the pharmacological effects of the drug. It is also known that (2S,6S)-hydroxynorketamine is an active and selective inhibitor of the a7 subtype of the nicotinic acetylcholine receptor; this activity was shown to contribute to the pharmacological responses associated with the antidepressant activity of (R,S)-ketamine. We postulate that in patients with CRPS, 1 factor contributing to resistance is an altered pharmacokinetic profile produced by enhanced elimination of active metabolites downstream of NK, which is mediated by hsa-miR-548d-5p. However, because we have relied on indirect evidence of a higher percentage of direct/indirect bilirubin in poor responders, indicating increased UDP-GT enzyme activity, additional studies investigating hydroxynorketamine and its downstream metabolites along with their glucuronide conjugates in plasma and urine will provide direct evidence for the role of miR-548d-5p in mediating response to ketamine therapy in responders and poor responders.

.

They noted a significant difference in body weight between responders and nonresponders (heavier), but not in duration of disease and analgesic response to ketamine. Toward that end, they will publish separately upon

.

… investigating the link between miR-34a, which showed 28-fold reduction in poor responders relative to responders (Table 2), and the neuroendocrine system….

.

From the Conclusion

.

Our studies showed that miR-548d-5p can regulate UDP-GT but not CYP3A4, suggesting that UDP-GT activity in responders and poor responders may be mediated by differences in the level of circulating miR-548d-5p. Lower levels of miR-548d-5p in poor responders before treatment could result in higher UDP-GT activity, leading to the production of more inactive glucuronide conjugates and faster elimination of active ketamine metabolites downstream of NK. Thus, the levels of hsa-miR-548d-5p could minimize the therapeutic efficacy of ketamine and pain relief. Differences in miRNA signature can thus provide molecular insights distinguishing responders from poor responders. High failure rates of drugs targeted to treat neuropathic pain warrant changes in approaches. Studies targeting well-defined patient populations for clinical trials will play a crucial in developing drugs that may be efficacious in a subset of patients. Extending this approach to other treatment and outcome assessments might permit stratification of patients for maximal therapeutic outcome.

.

.

How frustrating it is for patients and family who must cope with an intractable condition such as pain or Bipolar Disorder or treatment resistant Major Depression that has failed all commonly prescribed medications. For all of them, we need changes in approach.

.

“High failure rates of drugs targeted

to treat neuropathic pain

warrant changes in approaches.”

.

Perhaps scientists reading this would comment upon how it may relate to tolerance as it differentially occurs in those receiving intermittent ketamine vs continuous intravenous infusion.

.

Dysregulation of miRNA’s has been shown in psychiatric disorders including depression and schozophrenia, neurodevelopmental disorders, cognitive dysfunction,  epilepsy, chronic pain states with implication for the cause and treatment of these disorders.

.

Research targeting miRNA’s as novel treatment for depression has shown that chronic fluoxetine, repeated electroconvulsive shock therapy, and acute ketamine have the capacity to alter hippocampal miRNA levels.

.

It is hoped these tests may be available someday clinically as the cost of off-label treatment not covered by insurance is a great burden for those already disabled by intractable pain or treatment resistant depression.

Intranasal Ketamine in Major Depressive Disorder


.

.

Physicians at Icahn School of Medicine at Mount Sinai, New York, studied intranasal ketamine in 18 patients with Major Depressive Disorder, published in 2014:

.

A Randomized Controlled Trial of

Intranasal Ketamine in Major Depressive Disorder

.


Conclusions

.

“This study provides the first controlled evidence for the rapid antidepressant effects of intranasal ketamine. Treatment was associated with minimal adverse effects. If replicated, these findings may lead to novel approaches to the pharmacologic treatment of patients with major depression.”

.

I have previously posted more detail on this study. They report a significant antidepressant effect occurred as early as 40 minutes in some. I have seen some respond in seconds. But the dose is unique and specific to each person and there is no response until that dose is reached.

.

~~~

.

It is hoped that more studies will be funded, though that seems unlikely since congress slashed the NIH budget in 2010 by the unthinkable 30%, never done in history.

.

Entire generations of scientists are now lost forever.

.

Ketamine Safety

.

Ketamine is one of the safest medications I have prescribed in 40 years of medicine. And I meticulously obtain laboratory studies at least twice a year to verify any potential harm as it has been reported in addicts that it may affect bladder, kidney, liver or biliary system. I first prescribed ketamine about 14 years ago for intractable pain rated 10 on a scale of 10 for 30 years; and prescribed ketamine since Spring 2012 for Major Depression. For years I searched to find a spray with a metered dosing system. Thus since late 2011, intranasal has been the delivery I find most useful. When given as nasal spray or under the tongue, not swallowed, it goes straight to the bloodstream, bypassing the liver, and works for depression because the liver does not convert it to a different metabolite.

.

Nevertheless, it is important to stress that ketamine must be monitored for any possible adverse effects including toxicity and/or addiction. I require long distance patients to be followed by a psychiatrist or psychologist regularly while on ketamine. So far, my returning patients have been stable for years.

.

Further, when given by the nasal or sublingual route, I do not see the side effects that my anesthesiology colleagues see after I.V. infusion. I’ve been in board meetings with some of the finest anesthsiology pain specialists in the country sharing and comparing experience. I don’t see those complications. But that is what is published and I.V. is how it is given in the few centers where ketamine is used for treatment of Major Depression or Bipolar Depression.

.

Ketamine is a short acting medication whether it is given I.V. or nasally or under the tongue. But it is quite bitter and most prefer nasal delivery.  Review the case study of the professional who traveled out of state once or twice weekly for one year to receive I.V. ketamine. She had failed ECT 9 or 10 times – memory loss was so bad she got lost in her own neighborhood. She now does very well on a small dose every 48 hours given nasally. In the same post, I reported the patient with Juvenile Bipolar Disorder, Fear of Harm phenotype whose profound thermoregulatory abnormalities respond in seconds to ketamine, with a very small dose of 10 mg nasal spray every 3 days. That’s it! Temperature responds in seconds, and the depression responds in 10 minutes in her case.

.

Unfortunately research protocols require the study of fixed dosages in order to be a cost effective study for one sample size at one dose to be even slightly meaningful, even then 18 patients studied at Mt. Sinai is a small study at the one dose they used.

.

The principle that I have always used is “start low, go slow.” That allows for the discovery that some large men may require the tiniest dose and some tiny 90 pound seniors may require some of the largest doses I’ve seen. It cannot be predicted by body weight. Anesthesiologists generally think in terms of mg/kg body weight, for example the 0.5 mg/kg I.V. generally used for depression. But ketamine’s dosage variance is unrelated to weight. That likely explains why some develop frightening symptoms when given IV, and others do not respond. One size does not fit all. That method either under-doses or overdoses.

.

There are case reports on this website giving examples of some individuals I have seen with Major Depressive Disorder. One man is unusual in needing a small dose only every 6 to 8 weeks, but most use the nasal spray daily or every second or third day. I suspect that after initially starting ketamine on a daily basis for one or two weeks, the frequency of dosing may be lowered to every two or three days. Less is more.

.

Professor David Feifel at UCSD guesstimates that ketamine helps 70% of persons with Major Depression. I think that’s a fair statement given that we are unlikely even to see the unknown number who remain at home, forever feeling they are unable to leave their confinement. We know that effects of ketamine are blocked in mice that are deficient in BDNF. We may speculate that when ketamine fails in persons with Major Depression, that may be due to lack of BDNF. We know exercise helps Major Depression and exercise increases BDNF. Much more research is needed.

.

The use of ketamine is essentially a first line drug for Complex Regional Pain Syndrome (CRPS). That may never be said in publications, but that has been the case for years in persons with CRPS who have failed all other medications. I specialize in CRPS, a form of neuropathic pain that leads to suicide more often than any other pain syndrome.

.

For pain, intranasal ketamine is far shorter lasting, typically three hours, rarely six. And requires doses far higher than for Major Depression or Bipolar Depression. Even then, when used for pain six times daily in very high doses, it has proven to be profoundly safe with few if any side effects that last less than half an hour, if present at all.

.

.

Inflammation

.

The role of inflammation and glia in the pathogenesis of depression has been well established since 2000, and discussed here. The study of ketamine has taken on new life with the discovery that it profoundly lowers pro-inflammatory cytokines produced by microglia. Inflammatory cytokines have been shown to be elevated in chronic pain and in Major Depression. That is why I feel it is important to prescribe adjuncts that also lower inflammatory cytokines. And patients with Major Depression and Bipolar Depression have reported the adjuncts make ketamine stronger and last longer. Some don’t even need ketamine after awhile, but remain on the adjuncts.

.

Ketamine is not a cure and I find it is best used with adjunct medication. In my experience, ketamine and adjunct medications are likely to help as long as prior to treatment, patients are still able to function, to work at least somewhat. I do have 4 patients in the last four years who have not left their home or their bed for many years, and they failed to respond. Sadly, one older woman had to be institutionalized for life, her melancholic depression was so deep. When ketamine is even partially effective, I have patients who had been too fatigued to work before treatment, yet who are able to return to graduate school for a PhD and do well for years on a stable dose. It is immensely rewarding to be a part of this unique therapy, to see them regain life and function after years of misery and disability.

 

.

.

Studies

.

S-Ketamine

It is my hope to be able to compare S-ketamine, that is not yet FDA approved, with the racemic* ketamine that we now have, that was FDA approved in 1970 in high dose as an anesthetic. Obviously we do not use high anesthetic doses for control of pain or Major Depression. I understand unfortunately that when clinical studies are completed, S-ketamine will be available only in emergency departments.

.

*Racemic means the molecule has equal amounts of left and right-handed enantiomers (mirror images) of a chiral molecule (meaning, you cannot superimpose the left hand with the right hand. They mirror but do not superimpose). Thus both left and right racemic ketamine mixture has been FDA approved, but the S-ketamine, the left sided molecule is considered a different drug, and must be FDA approved.

.

Without FDA approval, ketamine can be studied with FDA permission that provides an Investigational New Drug (IND) application.

.

Given the lack of funding for almost any research in this country, I would consider doing a patient-funded study if patients showed interest. It would be modeled on the intranasal study published in the Mt. Sinai study, above, i.e. short term, randomized, double blind, placebo controlled.

.

It is reported that S-ketamine may be more effective with fewer side effects. This must be proven and cannot be taken at face value without several studies. Shockingly, some publications in recent years have been fabricated and woven into mythology.

.

.

Finally, ketamine is off-label for pain and for major depression.

.

Papolos et al have published Clinical experience using intranasal ketamine in the treatment of pediatric bipolar disorder/fear of harm phenotype

..

“Ketamine administration was associated with a substantial reduction in measures of mania, fear of harm and aggression. Significant improvement was observed in mood, anxiety and behavioral symptoms, attention/executive functions, insomnia, parasomnias and sleep inertia. Treatment was generally well-tolerated.”

Ketamine – small doses work in depression and bipolar disorder


.

.

Everyone is very edgy right now with depression. Media is sensationalizing, which is the worst thing to do. I even hesitate to write this now.

.

Ketamine really does work

.

Small doses may be all that’s needed. Even large doses are safe.

.

Two Cases

.

I hate to play on emotion that is strong right now, but Robin Williams might be alive today if his doctors prescribed ketamine nasal spray.

.

Every one, doctors and patients alike, worry about ketamine. It sells newspaper headlines and distorted media coverage that then overtakes the life saving stories of its profound safety when used under good medical supervision. Experience helps.

.

Two cases from yesterday and today really must be shared. These two patients would not be alive today if they did not have ketamine nasal spray for their depression.

.

I don’t mean to say every one will respond to these extremely tiny doses, but it’s always exciting to hear the effective dose is simply so small.

.

These details would make good case reports if time permitted, but there is never enough time. I wanted simply to say a few things now because these two patients were seen.

.

**1**

.

In May 2014, saw a fifty-ish woman who is now responding to 20 mg (4 nasal sprays) given as one dose every 48 hours. She has been treated at well known university psychiatry departments, failed ECT 9 or 10 times – memory loss was so bad she got lost in her own neighborhood. Received IV ketamine once or twice weekly for one year before I saw her.

.

Diagnoses:  dysthymia as long as she can remember, and 25 years of Major Depressive Disorder, PTSD, anxiety, etc. Olympic level athlete —

.

.

**2**

.

Second patient now in late teens, Juvenile Bipolar Disorder/Fear of Harm phenotype, profound thermoregulatory changes respond in seconds to ketamine, dose of 10 mg nasal spray every 3 days. That’s it! Temperature responds in seconds, and the depression responds in 10 minutes in her case. She was so violent before treatment that she had been hospitalized 7 times in 2-1/2 years. Doing very very well. And the low dose naltrexone, by the way, is involved in thermoregulation.

.

I should mention, no side effects whatsoever. I have never seen toxicity. I watch kidney and bladder function meticulously, and patients with massive pain on very high doses have never had any organ toxicity.

.

.

NEURO-INFLAMMATION AND GLIA – brain on fire.

.

I mention Olympic athlete because so many people I see with Complex Regional Pain Syndrome – the pain that so often leads to suicide, seems to occur more often in top level athletes, either state or national level, professional or sponsored in their teens. Yes, they occur in others, but there is a striking predominance in athletes for unknown reasons.

.

Glia are triggered by trauma, then they become activated and produce pro-inflammatory cytokines. Inflammation is out of balance. Ketamine profoundly reduces the pro-inflammatory cytokines, and so does low dose naltrexone. I write about these mechanisms with more frequency that anything else. This is what we must address – the brain is essentially “on fire.” And this inflammation, these pro-inflammatory cytokines, are involved in almost every known disease: Alzheimer’s disease, Parkinson’s disease, ALS, chronic pain, major depressive disorder, cancer, autoimmune disease, and atheroscloerosis.

.

Inflammation kills. Unfortunately this new research on glia and inflammatory diseases, these diseases could be called gliopathies, all based on new research since the turn of the century. We now know glia are your innate immune system in brain and spinal cord. They need a balance the anti-inflammatory cytokines with the pro-inflammatory cytokines. Inflammation may be lifesaving when you have caught a virus, but not as a steady diet. Give the brain a break or it leads to hyperexcitable glutamate that triggers calcium flooding into the neuron, cell death, brain atrophy and memory loss. Seen in people with Major Depression and those with chronic low back pain.

.

Do doctors know about the innate immune system? or the receptor that won the Nobel Prize 2 and 1/2 years ago? or glia?

.

Answer: no.

Dr. Papolos’ video on treatment points out, ketamine nasal spray is off-label

for Bipolar Disorder. And I add, ketamine is off-label for pain and for major depression.

He posts this:

Do You Have Depression? Are you the one who runs into snow wearing shorts?


.

.

.Th

Since you were a baby, thermoregulation may be the source of the problem

that triggers your depression or the depression of someone you know.

.

You may be a candidate for a research study if you have other key characteristics.

Treatment may help.

.

Contact the Juvenile Bipolar Research Foundation.

.

OR

.

Demitri Papolos, MD, is the psychiatrist who, in collaboration with many others, has discovered that body temperature appears to be at the origin of this condition:

.

Juvenile Bipolar Disorder, Fear of Harm phenotype.

.

Dr. Papolos has written many publications and has published a book, with Janice Papolos, describing this serious disorder. “The Papoloses were the first to sound a national alarm about the dangers of using antidepressant and stimulant drugs with this population of children.”

.

Either the link to Dr. Papolos or the Research Foundation, above, can give you further information on treatment.

.

.

I am not affiliated with Dr. Papolos, but wish to call attention to the dedicated academic work they have been doing for this devastating mood disorder. .

.

Of interest, thermoregulation appears to be modulated by low dose naltrexone (LDN).

.

It has been anecdotally reported to relieve heat intolerance in persons with Multiple Sclerosis.

I have seen a response with Juvenile Bipolar Disorder/Fear of Harm, and

severe postmenopausal hot flashes were completely reversed by LDN.

.

Naltrexone blocks the TLR4 receptor. There is a strong literature on TLR4 and temperature regulation. This raises the interesting question whether anyone has done objective studies to show that low dose naltrexone may be modulating temperature in patients. If you have experience with this, please add your comments below.
