Constant Pain Can Lead to Diabetes, High Cholesterol and Heart Problems

By Dr. Forest Tennant, PNN Columnist

Intractable Pain Syndrome (IPS) is constant pain with cardiovascular, metabolic and hormonal complications. Constant pain is a severe stressor that causes the adrenal hormones cortisol and adrenalin to rise in the blood as the body attempts to reduce stress.

These hormonal elevations can lead to serious metabolic consequences that need to be well known to persons who have IPS, as well as their family and medical practitioners. High levels of adrenalin cause blood pressure and the pulse rate to rise. When cortisol is elevated, it causes the hormone insulin and blood sugar (glucose) to rise in the blood.

If blood sugar remains too high for too long, a person can develop diabetes or pre-diabetes, which is often called “insulin resistance.” Most persons believe that diabetes is a metabolic disease and is unrelated to hormones. The fact is that insulin, cortisol and adrenaline are hormones.

In addition to diabetes, a person with constant pain is also at high risk of developing or experiencing any or all of the following: 

  • Heart Attack

  • Heart Pain (Angina)

  • Stroke

  • Dementia

  • Arteriosclerosis

Some persons with IPS have died suddenly and unexpectedly, sometimes while asleep. Often these cases are falsely labelled as a drug overdose.

There are three reasons for sudden, unexpected death in persons with IPS who are undertreated and have cardiovascular, metabolic and hormonal complications.

  • Cardiac Arrythmia

  • Adrenal Failure          

  • Hypoglycemia (Excess Insulin)

Every person with IPS needs to be evaluated for diabetes, pre-diabetes, hypertension, tachycardia and excess cholesterol. Steps must be taken to eliminate or reduce any or all of these IPS complications. Consult your medical practitioner at your earliest opportunity for an evaluation of these complications.

Stem Cells Could Help Diabetics Produce Their Own Insulin  

By Pat Anson, PNN Editor

With insulin prices soaring out-of-reach for many U.S. patients, there’s hope on the horizon for people with Type 1 diabetes. Researchers are making significant progress in developing stem cell therapies that could restore their ability to produce their own insulin.

Interim findings from two early stage clinical trials, published today in the journals Cell Stem Cell and Cell Reports Medicine, show that pancreatic endoderm cells derived from human pluripotent stem cells (PSCs) began producing insulin in diabetic patients within months of being implanted in a tiny device under the skin.

While the amount of insulin secreted by the cells was not enough to cure Type 1 diabetes, they were sufficient enough to reduce the insulin requirements of some patients by as much as 20% and increase the amount of time spent in their targeted blood glucose range. Both studies showed that the stem cells can survive up to 59 weeks after implantation.

"A landmark has been set. The possibility of an unlimited supply of insulin-producing cells gives hope to people living with type 1 diabetes," says Eelco de Koning, MD, of Leiden University Medical Center in the Netherlands, who co-authored a commentary published in Cell Stem Cell. "Despite the absence of relevant clinical effects, this study will remain an important milestone for the field of human PSC-derived cell replacement therapies as it is one of the first to report cell survival and functionality one year after transplantation."

There are a number of caveats here. Less than three dozen patients participated in the Phase 1/2 studies, the outcomes were highly variable, and there were no control groups to compare the results with. The implanted stem cells were also derived from donors – meaning the patients had to take immunosuppressive drugs to prevent their bodies from rejecting the implants, leaving them vulnerable to infections. At least two patients experienced serious adverse events associated with having their immune systems suppressed.

Researchers still need to determine at what stage the stem cells are optimal for transplantation and the best place to implant them. It is also not clear how long the cells remain effective and whether the need for immunosuppressive therapy can be eliminated.

But the studies demonstrate that stem cells can mimic the insulin-producing pancreas cells that diabetics lack.

"The clinical road to wide implementation of stem cell-derived islet replacement therapy for type 1 diabetes is likely to be long and winding,” de Koning says. "But an era of clinical application of innovative stem-cell based islet replacement therapy for the treatment of diabetes has finally begun."    

About 460 million people worldwide have diabetes mellitus, a disorder in which the body does not produce enough insulin, causing blood sugar (glucose) levels to be abnormally high.  In Type 1 diabetes, the body’s immune system attacks the insulin producing cells of the pancreas. Left untreated, diabetes damages blood vessels and significantly raises the risk of stroke, heart attack and diabetic neuropathy.

Diet, exercise and regular insulin injections can help control Type 1 diabetes. But with insulin selling for about $300 a vial in the United States – 10 times more than in other developed countries --  some diabetics have rationed or even stopped taking the life-saving injections.

Another encouraging stem cell study -- involving just one patient -- was recently reported by Vertex Pharmaceuticals. A chronically ill man with Type 1 diabetes who has been taking insulin injections for decades – up to 34 units per day – began producing his own insulin after being injected with an experimental stem cell product called VX-880.

As a test, researchers only injected him with about half the targeted amount of VX-880, but within 90 days the man had reduced his need for insulin injections by 91 percent.

“These results from the first patient treated with VX-880 are unprecedented. What makes these results truly remarkable is that they were achieved with treatment at half the target dose,” Bastiano Sanna, PhD, Executive Vice President of Vertex, said in a statement. “While still early, these results support the continued progression of our VX-880 clinical studies, as well as future studies using our encapsulated islet cells, which hold the potential to be used without the need for immunosuppression.”

Vertex plans to expand the study to eventually include up to 17 patients, at multiple sites in the U.S. and Canada.

Study Identifies Medications Most Involved in ER Visits

By Pat Anson, PNN Editor

Here’s a question for you: What type of medication is most likely to be involved in a visit to a hospital emergency room?

  1. Opioid pain relievers

  2. Blood thinners

  3. Psychiatric drugs

  4. Insulin

  5. Antibiotics

Given the well-publicized risks of addiction and overdose associated with opioids, you might assume it was opioid pain relievers. You’d also be wrong, according to a large new study that looked at medications associated with emergency department (ED) visits in the U.S. from 2017 to 2019.

CDC researchers looked at a representative sample of nearly 97,000 cases of adverse events involving medication and found that warfarin (Coumadin) and other anti-coagulant blood thinners – typically prescribed to reduce the risk of heart attack and stroke -- were the leading cause of ED visits.

Among patients of all ages, insulin was the second leading cause of medication-related adverse events, followed by psychiatric drugs, antibiotics and the over-the-counter pain relievers ibuprofen and acetaminophen. The opioid oxycodone came in last on a Top 10 list of drugs involved in ED visits.

The study findings, published in JAMA, help dispel many of the myths associated with the risks of opioids — at least in comparison to other widely used medications.

There are many reasons for someone to have an adverse reaction to medication, ranging from allergies to dosage errors to taking drugs intended for someone else. About a third of the ED visits were so serious, the patient was admitted for hospitalization.

Compared to seniors age 65 and older, young adults were significantly more likely to abuse a medication or to use it for intentional self-harm. Seniors were far more likely to only take a drug for its intended therapeutics use.

The age of a patient also plays a significant role in the type of drug they have an adverse reaction to. For example, the antibiotic amoxicillin was the leading cause of medication harm for patients under the age of 14; while the anti-anxiety drug alprazolam (Xanax) was the leading cause of adverse events for patients aged 15 to 44.  Insulin ranked first for patients aged 45-64; while warfarin was first for patients aged 65 and older.

Analgesics, sedatives and antidepressants were the drugs most likely to be abused. About 63% of adverse events involving prescription opioids were cases of “non-therapeutic” abuse, while 89% of cases involving benzodiazepines were classified as abuse. The vast majority of cases involving blood thinners, insulin or antibiotics were for their intended therapeutic use.    

The role of opioids in ED visits has been falling for over a decade. A 2017 study showed a significant decline in the number of patients admitted to U.S. hospitals for abusing opioid medication. Hospital admissions for overdoses from opioid medication started falling in 2010, the same year that opioid prescriptions peaked in the U.S.
