Seven Wonders in the World of Rheumatology
A Story of Romance, Reminiscences and Renaissance
Introduction
For centuries, the mysterious world of rheumatic diseases remained an enigma—a medical terra incognita where patients suffered from what was loosely called "rheumatism" and physicians had little more than aspirin and sympathy to offer. The term itself, derived from the Greek "rheuma" meaning flux or flow, reflected the ancient belief that these conditions resulted from harmful substances flowing through the body and settling in joints 9 .
Today, we stand witness to a remarkable transformation—a genuine renaissance in how we understand, diagnose, and treat these complex conditions. The field of rheumatology has evolved from rudimentary descriptions of "arthritis deformans" (the original term for rheumatoid arthritis) to a sophisticated understanding of immune pathways, genetic markers, and targeted therapies 9 .

The Therapeutic Revolution: Targeted Treatments and Personalized Approaches
Biologics and Pathway Precision
TNF inhibitors led the revolution, followed by drugs targeting IL-6, IL-1, and other cytokines 5 .
Development of B-cell depletion therapies and T-cell costimulation modulators provided further options 8 .
Latest innovations include dual-pathway inhibitors demonstrating dose-dependent efficacy 4 .
Cellular Therapies and Immune Reset
CAR-T cell therapy shows remarkable promise in autoimmune diseases 4 .
The RESET program demonstrated drug-free remission in conditions like SLE, myositis, and systemic sclerosis 4 .
In vivo CAR-T cell engineering represents a paradigm shift toward reprogramming the immune system 1 .

A Closer Look: In Vivo CAR-T Cell Engineering in Refractory SLE
Methodology
The groundbreaking experiment demonstrating in vivo CAR-T cell engineering represents one of the most innovative approaches in rheumatology:
- Nanoparticle Design: Developing specialized lipid nanoparticles (LNPs) containing mRNA sequences coding for CARs
- Targeted Delivery: Infusing these LNPs intravenously to target specific immune cell populations
- In Vivo Reprogramming: Leveraging the body's cellular machinery to produce CAR-T cells directly within the patient
- B-cell Depletion: Resulting CAR-T cells eliminate pathogenic B-cells, fundamental drivers of SLE autoimmunity
This approach circumvented traditional CAR-T therapy requirements of cell extraction, external genetic modification, and reinfusion 1 .
Results and Analysis
Preliminary results from this innovative approach have been remarkable. Patients with treatment-refractory systemic lupus erythematosus achieved significant B-cell depletion and disease control through this in vivo engineering technique 1 .

Conclusion: From Romance to Renaissance
The journey of rheumatology mirrors the evolution of its terminology—from the vague but evocative "rheumatism" to the precise yet complex "ANCA-associated vasculitis" 9 .
The seven wonders of modern rheumatology—from autoantibody discovery and biomarker identification to targeted therapies, cellular engineering, and digital transformation—represent a collective triumph of the scientific spirit.
The romance of rheumatology lies in its ongoing mystery—the recognition that we still have much to learn about the immune system's complexities. The reminiscences honor the journey from diagnostic uncertainty to therapeutic precision.
The renaissance is happening now—in the clinics where patients receive treatments unimaginable a generation ago, in the laboratories where scientists unravel ever-deeper layers of immunological complexity, and in the lives reclaimed from what was once considered inevitable disability.
As we stand at this precipice of even greater discoveries—with gene editing, cellular reprogramming, and artificial intelligence poised to write the next chapter—we can appreciate how far the field has come while anticipating the wonders yet to emerge in this golden age of rheumatology.
