Abstract

To evaluate whether there is a relation between Korean red ginseng (KRG)-intake and the suppression of immune hyperactivation in HIV-1-infected patients, we measured serum soluble CD8 (sCD8) over 31-48 months in 168 patients. They were divided into four groups; HIV-1-infected control (n = 49), zidovudine (ZDV) group (n = 22), KRG group (n = 48), and combination of KRG and ZDV group (n = 49). In control, sCD8 and the ratio of sCD8/CD8+ T cells significantly increased by 33% (paired t-test, P < 0.05) and 54% over $21\;{\pm}\;13$ months (P < 0.001), respectively. In ZDV group, sCD8 decreased within first 6 months and then showed steady increase and the ratio also increased over $19\;{\pm}\;10$ months. In KRG group, sCD8 and the ratio of sCD/CD8+ T cells continuously decreased by 45% (P < 0.01) and 19% over $19\;{\pm}\;11$ months (P < 0.05), respectively. In combination group, sCD8 gradually decreased by 29% (P < 0.01). There was a clear difference in the changes in serum sCD8 over time among 4 groups. There was no rebound phenomenon in KRG group as shown in ZDV group. These results suggest that KRG-intake suppresses immune hyperactivation state by HIV antigen itself in the HIV-infected patients.

고려홍삼이 HIV-1 감염자에게서 바이러스의 활발한 증식으로 유발된 면역계의 과활성화를 장기간에 걸쳐 억제하는지 살펴보기 위해 면역 활성화 지표인 soluble CD8항원(sCD8)을 측정하였다. HIV-1 감염 대조군 49명, zidovudine (ZDV) 복용군 22명, KRG 복용군 48명, KRG와 ZDV 병용군(49명)을 대상으로 하였다. HIV-1 감염 대조군에서는 혈청 sCD8 농도가 31-48개월 동안 33% 증가하였으며(P < 0.05), sCD8/CD8+T 림프구 비도 $21{\pm}13$개월동안 54% 증가하였다(P < 0.001). ZDV 복용군에서는 혈청 sCD8농도가 초기 6개월 동안은 감소하였으나 그 이후로는 서서히 증가하였으며, sCD8/CD8+T 림프구 비도 증가하였다. KRG 복용군은 sCD8 농도가 31-48개월 동안 45% 감소하였으며(P < 0.01), sCD8/CD8+T 림프구 비도 $19\;{\pm}\;11$개월 동안 19% 감소하였다(P < 0.05). 병용군에서는 sCD8 농도가 31-48개월 동안 29%(P < 0.01) 감소하였다. 추적관찰 기간 동안 각 군간의 sCD8 농도 변화가 명확한 차이를 보였으며, KRG 복용군에서는 ZDV 복용군에서 관찰된 'rebound현상'(sCD8이 초기에 감소하다가 다시 증가하는 경향)이 없었다. 결론적으로 본 연구에서는 HIV-1 감염환자에서 KRG를 장기간 복용시켰을 경우 sCD8 농도가 지속적으로 감소하여, KRG가 면역계의 소모적인 과활성화 상태를 방지함을 알 수 있었다.
