CD19 Chimeric Antigen Receptor (CAR) T-Cell Therapy for Systemic Autoimmune Diseases

A small number of drugs have been the sole stay of conventional treatment for autoimmune illnesses for the past 10 years. These medications have a number of side effects that restrict their usage and necessitate continuous administration to keep a patient in a state of remission. While many new treatments are being researched to address this problem, chimeric antigen receptor (CAR) T-cell therapy currently shows the greatest potential. Current medical guidelines do not currently advocate the use of this medicine because it is still in its early stages of development due to continuing clinical research. Therefore, the aim of this systematic review was to determine what new findings have been reported in recent studies about the safety and efficacy of CAR T-cells. From the nine studies collected in total, it was found that systemic lupus erythematosus (SLE) was the most often researched autoimmune disease. The CAR T-cell therapy had noticeable results after one to two months on average. The most frequent adverse effect was cytokine release syndrome (CRS), which was treated cautiously and infrequently necessitated extensive intervention. All serological tests showed improvement, and clinical remission was always achieved. This review concludes that, due to the one-time infusion and low adverse reaction rate, the therapy not only outperforms conventional drugs but is also more practical. There is even more cause to look forward to the full deployment of this innovative therapeutic alternative, as variations of the therapy are currently being explored.
