Forskningen bag behandling med µguld

Behandling med µguld bygger på forskning i metallisk gulds lokale biologiske virkning i væv. Forskningen har blandt andet undersøgt, hvordan små partikler af metallisk guld kan påvirke lokale inflammatoriske processer tæt på det sted, hvor guldet er placeret.

På Auron Klinikken anvendes µguld som en lokal injektionsbehandling ved slidgigt og vedvarende ledsmerter. De sterile guldmikropartikler injiceres i det smertefulde led sammen med hyaluronsyre og forbliver lokalt i det behandlede område.

Den biologiske virkning er, at µguldpartiklerne over tid frigiver små mængder guldioner i vævet. Formålet er at dæmpe lokal inflammation og dermed reducere smerter og forbedre funktion i det behandlede led.

Behandlingen tilbydes efter en individuel lægefaglig vurdering. Effekten kan variere fra patient til patient.

Du behøver ikke vide på forhånd, om behandling med µguld eller hyaluronsyre er relevant for dig. Det vurderes først ved en forundersøgelse.

Intraarticular gold microparticles using hyaluronic acid as the carrier for hip osteoarthritis. A 2-year follow-up pilot study

In this study, we aimed to evaluate whether there may be a clinical relevant effect of intra-articular injection of gold microparticles on hip osteoarthritis.

A cohort of 22 patients, aged ≥ 18 years, with pain ≥ 3 months, and Kellgren-Lawrence OA grade 2–4, were included. Metallic gold 20 mg, 72.000 pieces, 20–40 µ-meter BerlockMicroImplants (BMI) were injected into the hip joint using hyaluronic acid as the carrier. In total, we treated 26 hip joints.

The primary outcome was the Western Ontario and McMaster Universities Arthritis Index (WOMAC). WOMAC pain decreased from 11 (2–20 to 3 (0–8), stiffness from 6 (0–8) to 1 (0–4), and activity from 43 (18–68) to 11 (0–27), all P = 0.0001. When adjusting for the minimally relevant differences, the P-values were 0.0015 for WOMAC pain, 0.26 for stiffness, and 0.011 for activity. Combined intraarticular treatment with metallic gold microparticles and hyaluronic acid may improve hip joint pain and function. Joint stiffness did not improve when assessed against the minimal clinically relevant difference.

Inhibition of Local Inflammation by Implanted Gold: A Narrative Review of the History and Use of Gold

Gold is highly prized for its luster, is malleable, and may have been among the first metals used for medical purposes by humans. The first documentation of the use of gold metal as a medical device is in 4500-year-old Egyptian mummies. The ancient Egyptians used dental implants in one form or another to replace missing teeth and tried to stabilize teeth that were periodontally involved using ligature wire made of gold.

NanoGold and μGold inhibit autoimmune inflammation: a review

The newest data on metallic gold have placed the noble metal central in the fight for the safe treatment of autoimmune inflammation. There are two different ways to use gold for the treatment of inflammation: gold microparticles > 20 μm and gold nanoparticles. The injection of gold microparticles (μGold) is a purely local therapy. μGold particles stay put where injected, and gold ions released from them are relatively few and taken up by cells within a sphere of only a few millimeters in diameter from their origin particles.

Metallic gold slows disease progression, reduces cell death and induces astrogliosis while simultaneously increasing stem cell responses in an EAE rat model of multiple sclerosis

Multiple sclerosis (MS) is the most common neurodegenerative disease in the Western world affecting younger, otherwise healthy individuals. Today no curative treatment exists. Patients suffer from recurring attacks caused by demyelination and underlying neuroinflammation, ultimately leading to loss of neurons. Recent research shows that bio-liberation of gold ions from metallic gold implants can ameliorate inflammation, reduce apoptosis and promote proliferation of neuronal stem cells (NSCs) in a mouse model of focal brain injury

Intra-articular injection of gold micro-particles with hyaluronic acid for painful knee osteoarthritis

Recently, in an open pilot study, we found up to two years, a potential pain-relieving effect of intra-articular gold micro-particles using the patient’s synovial fluid for patients with knee osteoarthritis (KOA). During the study the excluded group of patients, due to multisite pain, co-morbidities, and other exclusion criteria., received intra-articular gold micro-particles using hyaluronic acid,. We aimed to identify if pre-treatment characteristics influence the global outcome two years after intra-articular treatment for painful KOA with gold microparticles using hyaluronic acid.
