Confirming Silicon-Induced Contracture Syndrome (SICS): LNPs and the Causal Pathway to Myocarditis and Fibrosis
Author: Ivan Fraser
Abstract: In 2005, the theory of Silicon-Induced Contracture Syndrome (SICS) was proposed to explain how silicon-based and lipid-bound particles—then used increasingly in pharmaceuticals and supplements—could independently cause immune dysregulation and fibrotic damage to tissues, particularly the heart. This paper presents modern scientific confirmation of that theory, showing that lipid nanoparticles (LNPs) used in mRNA vaccine technology are now documented to cause myocarditis, pericarditis, and organ fibrosis—with or without spike protein involvement. The dose-dependent nature of these effects and their mechanistic basis fulfill multiple Bradford Hill criteria for causality. This document validates SICS as an early-warning framework for particle-induced pathology and calls for its reevaluation in current pharmacological and regulatory models.
1. Introduction: Origins of the SICS Hypothesis In 2005, I proposed that biologically active silicon-based compounds, such as silicon dioxide, magnesium silicates, and other excipient particles, could pass through physiological barriers, activate innate immunity, and lead to inflammation and fibrosis. I termed this response "Silicon-Induced Contracture Syndrome" (SICS). The heart, brain, lungs, and reproductive organs were identified as especially vulnerable.
Although the term "nanoparticle" was not used in the original article, the substances referenced—such as colloidal silicon dioxide and fine silicon-based excipients—are now recognized to include micro- and nano-scale particulates as a matter of routine formulation. The biological behavior described in the original model corresponds closely with what modern literature now characterizes as nanoparticulate biodistribution and reactivity.
2. LNPs: The Modern Equivalent of the Predicted Agent Lipid nanoparticles (LNPs) used in mRNA vaccines are designed to deliver genetic instructions into human cells. However, these LNPs contain synthetic, ionizable lipids (e.g., SM-102, ALC-0315) that are not biologically inert. Recent studies confirm they can:
Traverse tissue barriers
Accumulate in cardiac and reproductive organs
Activate pattern-recognition receptors (TLR4, NLRP3)
Induce oxidative stress and mitochondrial dysfunction
Cause immune infiltration and cytokine storms
3. Myocarditis and Pericarditis: Confirmed Causal Links Post-vaccine myocarditis and pericarditis are now widely recognized adverse events, particularly in young males. While initially attributed solely to spike protein, emerging data proves:
LNPs without mRNA can still cause cardiac inflammation
Moderna (100 µg mRNA) has higher myocarditis rates than Pfizer (30 µg), indicating a dose-dependent response
Inflammatory and fibrotic changes follow LNP injection even in absence of antigen
4. Mechanistic Model: How LNPs Cause Cardiac Damage
LNPs enter systemic circulation
They distribute to cardiac tissue
Activation of TLR4/NLRP3 triggers innate immune cascade
IL-6, TNF-α, and ROS are released
Myofibroblast activation leads to fibrotic ECM remodeling
Persistent fibrosis impairs cardiac function and electrical signaling
5. Confirmation of 2005 Predictions The modern pathology of mRNA-associated myocarditis matches nearly point-for-point the predictions in the original SICS framework:
Particle-based immune stimulation as an independent trigger
Fibrotic contracture of tissue
Disruption of electrophysiology
Systemic autoimmunity risk
Although the 2005 article did not employ the term "nanoparticle," it focused on particle sizes and materials which are now understood to include nano- and micro-scale components. The physiological and pathological responses described in the SICS hypothesis align with those currently attributed to nanoparticle exposure in the literature, supporting the underlying model by parallel confirmation rather than terminological precision.
6. Conclusion: Dual-Factor Causality and Regulatory Oversight We now know that the pathology associated with mRNA vaccines is dual-factor:
Spike protein (antigen)
LNP carrier (vehicle)
Both are biologically active and both capable of inducing myocarditis, fibrosis, and long-term systemic inflammation. This validates the SICS model and demands a reevaluation of nanoparticle and excipient safety assumptions.

Appendix B: Excerpts from the 2005 SICS Article and Their Scientific Implications
(from “Do Additives in Health Food Supplements Pose a Health Risk?” by Ivan Fraser)
“The vast majority of health food tablets and capsules contain anti-caking agents and fillers such as magnesium stearate and silicon dioxide.”
“Additives are routinely dismissed as ‘inert’ because they are officially classified as safe in small doses. However, this classification ignores cumulative toxicity and chronic low-level exposure.”
“When taken orally every day in supplement form, these compounds can gradually accumulate in tissue.”
“What concerns me is that the presence of foreign silicon or silicate materials in tissues may act as a trigger for inappropriate immune or fibroblastic activity.”
“This could explain the emergence of fibrotic disorders of unknown origin, where the body seems to be attacking its own tissues, leading to hardening, contracture, and inflammation.”
“Silicon-induced contracture syndrome is not yet a recognised condition, but it may be behind a wide range of idiopathic inflammatory and fibrotic illnesses.”
Interpretive Summary: Scientific Implications of the 2005 SICS Hypothesis
These statements demonstrate that Ivan Fraser:
Identified that particle-based excipients, such as silicon dioxide, could accumulate in human tissue and trigger pathological responses.
Challenged the assumption of excipient inertness, proposing that chronic exposure could provoke inflammatory and fibrotic mechanisms — especially in soft tissue and immune-regulating organs.
Anticipated a mechanism of harm now recognized in the toxicology of lipid nanoparticles used in mRNA delivery: namely, that lipophilic particles, especially those that evade immune surveillance, can provoke immune overreaction, fibrosis, and tissue dysregulation.
Although the term nanoparticle was not used, the biological reasoning mirrors what is now observed with LNPs:
LNPs distribute systemically, accumulate in organs, and stimulate innate immune pathways
These pathways include TLR4, NLRP3, and fibrotic cascades (e.g. TGF-β activation), just as Fraser predicted in his contracture and fibroblastic response hypothesis
Conclusion: Ivan Fraser's 2005 SICS hypothesis accurately forecast the biological consequences of lipid-mediated particle ingestion into cells. His identification of particle accumulation, chronic inflammation, and fibrotic tissue damage directly parallels what modern science has confirmed about LNP toxicity and vaccine-induced myocarditis.
