<![CDATA[Vaccinations & Neuro-Diversity --- The Need for a more Nuanced Approach]]>Fri, 25 Apr 2025 08:42:15 GMThttps://orchidadvocacy.org/translational-medicine-friday/vaccinations-neuro-diversity-the-need-for-a-more-nuanced-approach
Val's Take/Conjecture
  • ​If you ask Google AI about autism or ADHD, it's going to come back and say current research finds that Vaccinations do not "CAUSE" autism or ADHD.
  • I asked Google AI about vaccinations and NEUROIMMUNE Disorders, this is the result:
  • Vaccinations are generally safe and recommended for people with neuroimmune disorders, but timing and specific vaccine types should be considered.

  • Inactivated vaccines are considered safe, while live vaccines are generally avoided during immunotherapy.

  • Vaccinations must also be avoided during relapses or exacerbations of neuroimmune diseases. 
In fact, medical professionals do have guidelines regarding vaccinations and people with Neuro-Immune Disorders such as Multiple Sclerosis.
"COVID-19 vaccination increased the risks of depression, anxiety, dissociative, stress-related, and somatoform disorders, and sleep disorders while reducing the risk of schizophrenia and bipolar disorder.
"Therefore, special cautions are necessary for administering additional COVID-19 vaccinations to populations vulnerable to psychiatric AEs (Adverse Events)."
"CAUSE"
  • When it comes to "CAUSE" and not only Neuro-Developmental & Psychiatric Disorders but also classic Neuro-Immune Disorders & Cancer ----
    • ​There is often NOT 1 Cause --- they are "MULTI-FACTORAL" 
    • The Multitude of these FACTORS are driving the need for Individualized, Personalized Medicine.
ON THE OTHER HAND
  • People with Neuro-Developmental & Psychiatric Disorders, Classic Neuro-Immune Disorders and Cancer ----
    • ​Are the very people who would be most at risk for the most serious outcomes of some of these diseases.
Understanding Neuro-Developmental & Psychiatric Disorders as Neuro-Immune Disorders 
Conclusion: Studies indicate that the immune system’s response influences the emergence of ADHD.

The findings greatly improve our understanding of the interplay between immune responses and ADHD risk, aiding in the development of treatment strategies from an immunological perspective.
I just don't think it is that counter-intuitive that there might need to be some special considerations with regard to vaccines and Neuro-Immune Neuro-Developmental & Psychiatric Disorders.

We need to get out of the Anti-Vaxx/Conspiracy Theorist construction of this debate.

Recognizing legitimate issues and nuance supported by the evidence might help.

"DNA methylation is the addition of a methyl group to the molecular structure of DNA, which then alters the gene expression."

​DNA and RNA methylation directly linked for the first time
 (2025)
Val's Take/ Conjecture
  • I think  "Lifestyle Choices" are important AND so are DNA Methylation Patterns established In Utero.
  • There is a certain amount of "FETAL PROGRAMMING" that seems to be going on that we feel highly uncomfortable acknowledging.
  • These are DEVELOPMENTAL DISORDERS --- if we are missing that --- we're missing the boat.
"Here we synthesize these new findings from genomics and genetic causal inference studies on the role of immune dysfunction in major psychiatric disorders and reconcile these new data with pre-omics findings.

"By reconciling these evidences, we aim to identify key gaps and propose directions for future studies in the field."
"DNA methylation patterns are essential for the growth and maintenance of tissue-specific expression profiles in different cell types during development, and these patterns become set during in utero development."
"Our study indicates that male aging exert an influence not only on DNA methylation modification in sperm and pre-implantation embryo, but also on neurobehavioral abnormalities of their offspring.

"Repairing DNA methylation in pre-implantation embryos may offer a promising avenue for ameliorating abnormal social behavior in offspring."
"Ultimately, rather than a focus on therapeutic intervention during adolescence or adulthood, principles of prediction and prophylaxis in the pre- and perinatal and neonatal stages may best comport with the biology of schizophrenia to address the early-stage perturbations that alter the normative neurodevelopmental trajectory."

Highlights

Paternal immune activation might enhance schizophrenia risk.


Epigenetic processes might mediate the effects of paternal immune activation.

Bi-parental immune priming seems to drive schizophrenia immunopathogenesis.
"This study demonstrates that the gut-germline axis influences sperm small RNA profiles and offspring physiology, with specific impacts on offspring affective and/or coping behaviors.

"These findings may have broader implications for other animal species with comparable gut microbiota, intergenerational epigenetics and developmental biology, including humans."

Neuropsychiatric Manifestations of Mast Cell Activation Disease (MCAS)
Picture
Abstract

Mast cell activation syndrome (MCAS) is an immune disease with an estimated prevalence of 17%.

Mast cell chemical mediators lead to heterogeneous multisystemic inflammatory and allergic manifestations.

This syndrome is associated with various neurologic and psychiatric disorders, including headache, dysautonomia, depression, generalized anxiety disorder, and many others.

Although MCAS is common, it is rarely recognized, and thus, patients can suffer for decades.

The syndrome is caused by aberrant mast cell reactivity due to the mutation of the controller gene.

​ A case series is presented herein including eight patients with significant neuropsychiatric disorders that were often refractory to standard medical therapeutics. Five patients had depression, five had generalized anxiety disorder, and four had panic disorder.

Other psychiatric disorders included attention-deficit hyperactivity disorder, obsessive compulsive disorder, phobias, and bipolar disorder.

All eight patients were subsequently diagnosed with mast cell activation syndrome; six had comorbid autonomic disorders, the most common being postural orthostatic tachycardia syndrome; and four had hypermobile Ehlers-Danlos syndrome.

All patients experienced significant improvements regarding neuropsychiatric and multisystemic symptoms after mast-cell-directed therapy.

In neuropsychiatric patients who have systemic symptoms and syndromes, it is important to consider the presence of an underlying or comorbid MCAS [Mast Cell Activation Syndrome].

<![CDATA[Atypical response to the common Epstein-barr Virus --- Auto-immune Disease, Cancer & Major Mental Illness]]>Fri, 18 Apr 2025 15:52:04 GMThttps://orchidadvocacy.org/translational-medicine-friday/atypical-response-to-the-common-epstein-barr-virus-auto-immune-disease-cancer-major-mental-illness
Val's Take/Conjecture
  • It's estimated that 90 to 95% of the population have the Epstein-Barr Virus.
  • So the virus itself is far from rare --- what's rare in various diseases and disorders is an ATYPICAL RESPONSE to the Epstein-Barr Virus.
  • Further, Epstein-Barr often becomes a problem for people but often in the context of "Aging."
  • For younger people and re-activated Epstein Barr Virus as well as re-activated Microglia -- this may be a form of premature aging.
  • For people with Neuro-Developmental and Psychiatric Disorders, their Microglia may have been dysregulated IN UTERO and easily re-activated.
AUTO-IMMUNE DISEASE
  • Multiple Sclerosis (MS) is now greatly associated with the Epstein-Barr Virus.
  • Further, there is some overlap between MS and Bipolar Disorder.
"This clinical vignette with literature review is an illustration of the interesting, yet still unknown relationship between MS and affective disorders, where one might be influenced by the other but also have a common pathophysiology.

"This highlights that the dividing line between neurology and psychiatry, whose pathophysiology often takes place in the same organ, is often arbitrary."
PSYCHIATRIC DISORDERS
"Perspectives on the etiology of mental illness have evolved from demonic possession toward multisystem biologically based models that include gene expression, environmental triggers, immune mediators, and infectious diseases.

"Microbes are associated with a number of mental disorders, including autism, schizophrenia, bipolar disorder, depressive disorders, and anxiety disorders, as well as suicidality and aggressive or violent behaviors. "
CANCER
"Epidemiological studies have provided strong evidence that Epstein-Barr virus (EBV) lytic replication is linked to cancer development."

Val's Take/Conjecture
  • When we think about Neuro-Developmental and Psychiatric Disorders --- there is not 1 gene or 1 environmental factor or epigenetic factor that accounts for everything.
    • ​This very much sounds like Stanford Biology and Neurology Professor Robert Sapolsky --- "It doesn't work that way." 
Many Neuro-Developmental and Psychiatric Disorders are being conceptualized as beginning IN UTERO and then having "a life of their own."

<![CDATA[lactoferrin ---Selected recent research]]>Fri, 11 Apr 2025 19:32:51 GMThttps://orchidadvocacy.org/translational-medicine-friday/lactoferrin-selected-recent-research
Val's Take/Conjecture
  • NOTE:  I am NOT a doctor --- I'm not recommending any treatments.
  • On the other hand, I am recommending we investigate Lactoferrin further.
This is complicated, of course.
  • There is a study from 1982 showing that people with schizophrenia have MORE LACTOFERRIN.
At the time, this was thought to reflect an abnormal inflammatory response in people with schizophrenia.
Lactoferrin alleviates Western diet-induced cognitive impairment through the microbiome-gut-brain axis (2023)

​"Thus, Lf [Lactoferrin] intervention alleviated cognitive impairment by inhibiting microglial activation and neuroinflammation through the microbiome-gut-brain axis."
Abstract

Numerous harmful factors that affect the human body from birth to old age cause many disturbances, e.g., in the structure of the genome, inducing cell apoptosis [programmed cell death] and their degeneration, which leads to the development of many diseases, including cancer.

Among the factors leading to pathological processes, microbes, viruses, gene dysregulation and immune system disorders have been described.

The function of a protective agent may be played by lactoferrin as a "miracle molecule", an endogenous protein with a number of favorable antimicrobial, antiviral, antioxidant, immunostimulatory and binding DNA properties.

The purpose of this article is to present the broad spectrum of properties and the role that lactoferrin plays in protecting human cells at all stages of life.
Abstract

Nutrition during the early postnatal period exerts a profound impact on both infant development and later-life health.


Breast milk, which contains lactoferrin, a dynamic protein, plays a crucial role in the growth of various biological systems and in preventing numerous chronic diseases.

Based on the relationship between early infant development and chronic diseases later in life, this paper presents a review of the effects of lactoferrin in early life on neonates intestinal tract, immune system, nervous system, adipocyte development, and early intestinal microflora establishment, as well as the preventive and potential mechanisms of early postnatal lactoferrin against adult allergy, inflammatory bowel disease, depression, cancer, and obesity.

Furthermore, we summarized the application status of lactoferrin in the early postnatal period and suggested directions for future research.
"Our findings suggest that lactoferrin intake during lactation protects neurons by regulating microglial activation, thereby effectively reducing depressive symptoms in adults."

<![CDATA[Maternal Immune activation, Fetal Inflammatory REsponse syndrome]]>Tue, 08 Apr 2025 20:06:01 GMThttps://orchidadvocacy.org/translational-medicine-friday/maternal-immune-activation-fetal-inflammatory-response-syndromeand MULTI-SYSTEM Neuro-developmental & Psychiatric Neuro-immune developmental disorders
Conclusion:

Overall, MIA exposure in utero caused failure in UPR [unfolded protein response] as well as immune overreaction to the second attack of inflammation in offspring.

Our results suggested that prenatal exposure to MIA might contribute to the congenital inflammatory constitution after birth.
"Cytokine-mediated inflammation is increasingly recognized for playing a vital role in the pathophysiology of a wide range of brain disorders, including neurodegenerative, psychiatric, and neurodevelopmental problems. . . .
"As research advances, the creation of personalized, cytokine-centered therapeutics has the potential to alter the therapy landscape for brain illnesses, giving patients hope for better results and a higher quality of life."
Key points
  • Human studies are uncovering a role for maternal immune activation (MIA) in the pathogenesis of common neurodevelopmental disorders, such as autism spectrum disorder, attention-deficit/hyperactivity disorder and Tourette syndrome, in the offspring.
 
  • Prenatal, in utero and postnatal embedding of environmental factors in the epigenetic architecture of both the brain and the peripheral immune system can modulate individual susceptibility to neurodevelopmental disorders.
 
  • The effects of MIA, mediated by acute and chronic inflammation in pregnancy, are transduced to the fetus through inflammatory cell signalling pathways and epigenetic mechanisms.
  • Pathogen-associated molecular patterns, damage-associated molecular patterns and Toll-like receptors represent a convergent cellular pathway between heterogeneous environmental factors and innate immune activation.
​​
  • In conjunction with individual genetic risk, sex-related factors and second ‘immune’ hits during life, MIA-induced aberrant immune programming results in a loss of immune homeostasis, which is associated with behavioural abnormalities in animal models.
Children born to placentas meeting criteria for FIRS [Fetal Immune Response Syndrome] were more likely to be diagnosed with neuropsychiatric disorders.
Specifically, they were more likely to be diagnosed with
  • autism spectrum disorder,
  • conduct disorder,
  • adjusting for maternal history of
    • psychiatric disorders,
    • intra-partem substance use, and
    • prescriptions of anti-inflammatory drugs.
  • Children born with placental inflammation are at an increased risk to develop neuropsychiatric disorders.
  • This has profound implications for future research, and early detection, monitoring, and treatment in these children.
