Expanded CD8⁺CD38⁺ T Cell Population in Patients With Systemic Lupus Erythematosus Is Linked to Increased Infection Rates: A Prospective Study.

15 Our study is limited in several ways: (1) enrolled subjects were from one tertiary academic center limiting generalizability, albeit the population was racially diverse; (2) although differences were detected for the first three months of follow‐up, the small sample size and relatively short follow‐up period of the study most likely accounted for the detection of a statistical trend of increased infection rates for the whole follow‐up period.
