Old Age, B Cell Function and Count Are the Critical Factors for Predicting Infection Risk in Patients With Autoimmune Rheumatic Diseases Undergoing Immunosuppression: A Cohort Study

Older age, low IgG, low B cell count (CD19) predict susceptibility to infections; high neutrophil counts, low platelets, and elevated NLR are key predictors of developing infection in ARDs patients. Careful monitoring and tailored treatment strategies are essential to reduce infection risks. Further research is needed in this direction to develop predictive algorithms.
