Insights

Biological drugs, including TNF blockers, offer new hope for rheumatoid arthritis (RA) patients, improving symptoms and quality of life. Combination therapies and alternative biologics show promise for treatment resistance.

Area of Science:

  • Rheumatology
  • Immunology
  • Pharmacology

Background:

  • Rheumatoid arthritis (RA) is a chronic inflammatory disease causing joint destruction and disability.
  • Existing treatments often fail to fully control RA progression and symptoms.
  • Biological drugs, particularly TNF blockers, have emerged as a significant therapeutic advance.

Purpose of the Study:

  • To review the efficacy and safety of biological disease-modifying antirheumatic drugs (bDMARDs) in rheumatoid arthritis.
  • To compare the effectiveness of different biologic agents and combination therapies.
  • To discuss the role of biologics in patients with inadequate response to conventional treatments.

Main Methods:

  • Review of randomized clinical trials (RCTs) and long-term observational studies.
  • Analysis of data on TNF blockers, tocilizumab, abatacept, and rituximab.
  • Evaluation of treatment outcomes including clinical signs, radiographic progression, and quality of life.

Main Results:

  • TNF blockers improve RA signs, symptoms, and radiographic progression, especially when combined with methotrexate (MTX).
  • Alternative biologics like tocilizumab, abatacept, and rituximab are effective in patients unresponsive to anti-TNF agents.
  • Combined biologic and MTX therapy is generally well-tolerated and safe in the short term.

Conclusions:

  • Biological therapies represent a crucial advancement in managing rheumatoid arthritis.
  • Treatment selection should consider individual patient response, potential for combination therapy, and alternative mechanisms of action.
  • While improving quality of life, biological drugs significantly increase healthcare costs.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...

Drugs 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...

Combined Effects of Drugs: Antagonism

The combined effects of drugs can result in various interactions, of which an important type is antagonism. Antagonism is a mechanism where one drug inhibits or counteracts the effects of another drug. Antagonism can occur through various means, including receptor binding, allosteric modulation, functional interaction, chemical reactions, and pharmacokinetic processes.
The most common type is receptor antagonism, where one drug acts as an antagonist to block the effects of another drug by...
Principles of Drug Action01:24

Principles of Drug Action

Drugs are chemical substances that modify biological responses by interacting with macromolecular targets such as receptors, ion channels, transporters, and enzymes. Pharmacodynamics describes the course of action of drugs leading to the physiological effect at a specific site in the body.
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...
T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...
Effects of Chemicals: Overview01:27

Effects of Chemicals: Overview

Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
