title: The lymphoblastoid cell lines of recurrence condyloma acuminatum patients produce lower level of tumor necrosis factor stimulated with LPS.
abstract: To study the mechanism of Condyloma acuminatum (CA) recurrence, and the association of CA recurrence with the ability of the host derived lymphoblastoid cell lines (LCL) stimulated by LPS to produce tumor necrosis factor (TNF), EBV-transformed B LCL were used as TNF producing 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 patients) 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 decreased ability to produce TNF (23.72% +/- 7.41 vs 34.31% +/- 11.46, P = 0.0054), whereas CA non 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 to produce TNF. But the recurrence of CA was associated with the ability to produce TNF. It was also indicated that the TNF involved cellular immunity might play an important role in the clearance of the residual HPV by the host after treatment.
