To study the mechanism of Condyloma acuminatum (CA) recurrence, and the associa-tion of CA recurrence with the ability of the host derived lymphoblastoid cell lines (LCL) stimulatedby LPS to produce tumor necrosis factor (TNF), EBV-transformedB LCL were used as TNF pro-ducing cells. The ability of LCL stimulated by LPS to produce TNF was measured by bioassay.The results showed that the LCL from CA patients (including recurrent and non-recurrent CA pa-tients) produced similar level of TNF stimulated by LPS to that of normal controls (29.54% ±11.28% vs 34. 31%±11.46%, P=0. 1498). The LCL of CA recurrent patients produced significantly lower amount of TNF than that of non-recurrent CA patients (23.72%±7.41% vs 37.33%± 11.10%, P=0. 0032). Compared with the normal controls, CA recurrent patients showed a de-creased ability to produce TNF (23.72% ± 7.41 vs 34.31% ± 11.46, P = 0. 0054 ), whereas CAnon recurrent patients had the similar ability to the controls (37.33%±11.10 vs 34.31%±11.46,P=0. 4914). It was concluded that the onset of CA was not relevant to the individual's ability toproduce TNF. But the recurrence of CA was associated with the ability to produce TNF. It was al-so indicated that the TNF involved cellular immunity might play an important role in the clearanceof the residual HPV by the host after treatment.
