Annexin-V analysis of apoptosis in peripheral lymphocyte sub-populations from South African rheumatoid arthritis patients and race-matched controls ex vivo

Cell population	Patients [Mean % (SEM)]	Controls [Mean % (SEM)]
Total PBL	30.0 (1.5)*	7.2 (0.9)
CD4+ PBL	26.3 (1.6)*	7.6 (0.8)
CD19+ PBL	60.5 (7.4)*	16.1 (1.9)

* Significant difference (p < 0.05; Mann-Whitney test). CD4, cytotoxic T-lymphocyte marker; CD19, pan B-lymphocyte marker.
