再生醫學和慢性痛症治療

甚麼是再生療法？

再生醫學是一個迅速發展的領域，利用身體自身的修復機制來修復、替換或恢復受損的組織。最終目的是緩解痛楚並改善患者的功能。

再生療法是一種再生醫學，主要利用身體的自我修復能力來治療慢性痛症。在過去，許多慢性痛症被誤認為是由發炎引起，而錯誤地把治療重點放在消炎。但隨著醫學進步，現在有更多醫學證據證明這些痛症是由退化引起，同時很多醫學證據也發現，用再生療法去治療這類型的痛症會比用消炎方法更為有效。這些包括骨關節炎、網球肘、肩膊旋轉肌炎、足底筋膜炎等。

再生療法背後的科學

再生療法背後的科學可以被理解為涉及幹細胞或原始細胞、細胞外基質 (ECM) 和細胞因子 / 生長激素的細胞成長的三角形。幹細胞或原始細胞是獨特的，因為它們可以變形為其他細胞類型。ECM 就像一個支持結構，幫助調節細胞功能。細胞因子和生長激素是參與細胞信號的分子，在治療過程中起著關鍵作用。

不同的再生療法技術

強化療法

強化療法包括將刺激性化學物質注射到受傷區域以引發炎症並促進癒合。大多使用葡萄糖來達至這個目的。然而，由於治療後會引起嚴重疼痛且效果不如其他後來發展的治療方法，所以使用葡萄糖的方式正在失寵。

血小板豐富血漿 (PRP) 療法

PRP 療法使用患者自身血小板的濃縮物注射，加速受傷的肌腱、韌帶、肌肉和關節的治療。血小板被活化以釋放細胞因子和生長激素，這些物質吸引白細胞和纖維母細胞到傷害部位。這種療法在過去幾十年中已經變得越來越受歡迎，目前許多活躍的研究都在關注這一主題。

間質幹細胞 (MSC) 療法

MSC 療法涉及到使用存在於各種組織中的 MSC，包括骨髓和脂肪組織。這些細胞可以區分和替代細胞。

Regenerative Medicine for Pain Management: An Overview

Regenerative medicine is a rapidly evolving field that uses the body's own healing mechanisms to repair, replace, or restore damaged tissue. This is achieved through the use of autologous or allogenic biologics, with the ultimate goal of alleviating pain and improving function in patients suffering from a variety of conditions.

What is Regenerative Therapy?

Regenerative therapy is a type of regenerative medicine that focuses on the body's natural ability to heal. It is used to treat a variety of conditions, many of which were previously thought to be inflammatory but are now understood to be degenerative. These include osteoarthritis, rotator cuff tendinitis, plantar fasciitis, and lateral epicondylitis.

The Science Behind Regenerative Therapy

The science behind regenerative therapy can be understood as a triangle of cell growth involving stem cells or progenitor cells, the extracellular matrix (ECM), and cytokines/growth hormones.

Stem cells or progenitor cells are unique because they can transform into other cell types. The ECM is like a support structure that helps regulate cell functions. Cytokines and growth hormones are molecules involved in cell signaling that play a crucial role in the healing process.

Different Regenerative Therapy Techniques

Prolotherapy

Prolotherapy involves injecting an irritating chemical into the injured area to trigger inflammation and promote healing. Dextrose is commonly used for this purpose. However, it is falling out of favor because it induces severe pain after treatment and is less robust compared to other later-developed treatments.

Platelet-Rich Plasma (PRP) Therapy

PRP therapy uses injections of a concentration of a patient’s own platelets to accelerate the healing of injured tendons, ligaments, muscles, and joints. The platelets are activated to release cytokines and growth hormones, which attract white blood cells and fibroblasts to the site of injury. It has been gaining popularity in recent decades, with many active research studies currently focusing on this topic.

Mesenchymal Stem Cell (MSC) Therapy

MSC therapy involves the use of MSCs, which are present in various tissues, including bone marrow and adipose tissue. These cells can differentiate and replace cells, promote tissue repair, and transfer organelles and exosomes or microvesicles.

Hyaluronic Acid Therapy

Hyaluronic acid therapy is a commonly employed treatment for joint pain. Some authors regard it as a form of regenerative therapy. It involves the use of hyaluronic acid, which provides physical lubrication, scavenges free radicals, regulates protein binding of cells, stimulates endogenous hyaluronic acid production, and has anti-inflammatory effects.

Safety and Efficacy of Regenerative Therapy

Regenerative therapy is generally considered safe if it involves autologous (from the same individual) substances and minimal manipulation of biological substances. However, the evidence for its efficacy is mixed, with some studies suggesting benefits for conditions such as tennis elbow, rotator cuff tendinitis, patella tendinopathy, plantar fasciitis, and osteoarthritis of the knee. More large-scale randomized controlled trials are needed to confirm these findings.

Conclusion

Regenerative medicine offers a promising approach to pain management, with the potential to treat or even cure diseases or conditions for which few effective treatment options exist. However, more research is needed to fully understand the mechanisms involved and to optimize the techniques used in regenerative therapy. As this field continues to evolve, it is hoped that it will provide new avenues for pain relief and improved quality of life for patients suffering from chronic pain conditions.
