Effect of corticosteroids on collagen synthesis
Surgery
|July 1, 1977
Summary
Corticosteroids may not inhibit collagen synthesis in wound healing as previously thought. Some steroid types and doses did not affect collagen, suggesting they might enhance collagen degradation instead.
Area of Science:
- Biochemistry
- Wound Healing Research
- Pharmacology
Background:
- Corticosteroids are known to impede wound healing, specifically contraction and epithelization.
- The precise impact of corticosteroids on collagen synthesis and wound remodeling remains incompletely understood.
- Existing research methods questioning steroid inhibition of collagen synthesis require re-evaluation.
Purpose of the Study:
- To investigate the effect of various corticosteroid treatments on collagen synthesis in different models.
- To clarify the mechanism by which corticosteroids influence wound healing and remodeling.
- To challenge the established view that steroids universally inhibit collagen synthesis.
Main Methods:
- Collagen synthesis was measured in cultured steroid-treated chick embryo calvaria.
- Assessed collagen synthesis in 5-day-old open wounds in corticosteroid-treated rats.
- Analyzed collagen synthesis in intralesionally injected human keloids.
Main Results:
- Collagen synthesis was suppressed only by long-term, high-dose systemic administration of sustained-release methylprednisolone (Depo-Medrol).
- Large, intermittent doses of triamcinolone and Solu-Medrol did not alter collagen synthesis rates.
- Intralesional triamcinolone softened and reduced human keloids without decreasing high collagen synthesis rates.
Conclusions:
- Corticosteroids do not consistently inhibit collagen synthesis during wound healing.
- The effects of corticosteroids on collagen synthesis are dose- and duration-dependent.
- Corticosteroids may promote collagen degradation, contributing to keloid softening and reduction.

01:13Collagens are the Major Structural Proteins of ECM
Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein subunits linked together to form a long, straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the body's movement.

01:11Fibril-associated Collagen
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
01:21Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...
01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
