Insights

Treat-to-target (T2T) strategies have improved rheumatoid arthritis (RA) care, but patient heterogeneity necessitates risk stratification. This review proposes new models for refractory RA and precision medicine implementation to optimize individualized treatment.

Area of Science:

  • Rheumatology
  • Immunology
  • Precision Medicine

Background:

  • Targeted therapies and treat-to-target (T2T) strategies have advanced rheumatoid arthritis (RA) management.
  • Significant patient heterogeneity in clinical practice complicates risk-stratified treatment selection and shared decision-making.
  • Considerations for infection, cardiovascular disease, malignancy, thromboembolism, and reproductive health are crucial in RA patient care.

Purpose of the Study:

  • To review current RA standard-of-care and identify unmet needs.
  • To propose a framework for understanding treatment-refractory RA, distinguishing inflammatory and non-inflammatory causes.
  • To outline strategies for identifying high-risk RA populations and implementing precision medicine.

Main Methods:

  • Literature review of current RA management and T2T strategies.
  • Proposal of a novel framework for refractory RA pathophysiology.
  • Discussion of challenges and a roadmap for precision medicine in RA.

Main Results:

  • A proposed model differentiates persistent inflammatory refractory RA from non-inflammatory refractory RA.
  • Strategies for identifying high-risk RA patients and minimizing overtreatment are discussed.
  • Barriers to precision medicine, including biospecimen access and trial design, are delineated.

Conclusions:

  • Refining T2T paradigms with a focus on refractory disease and precision medicine can lead to more optimized, individualized RA therapies.
  • Addressing challenges in pathophysiology understanding and precision medicine implementation is key.
  • A phased roadmap is proposed to facilitate the integration of these advanced concepts into clinical practice.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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...

Rheumatic Heart Disease III: Medical Management

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

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...
