Abstract:
Objective To investigate the compartmentalization of human immunodeficiency virus (HIV)infection and CD4~+ T lymphocytes between gastric mueosa and peripheral blood from patients with acquired immune deficiency syndrome(AIDS).Methods Thirty-five AIDS patients and 10 HIV seronegative subjects were enrolled in this study.The gastric mucosal biopsies were done by gastroscope and peripheral blood samples were collected.The digoxin labeled HIV-1 double-stranded cDNA probes for the long terminal repeat(LTR)and gag gene of HIV-1 genome were prepared by polymerase chain reaction(PCR).In situ hybridization was used to detect HIV infection in gastric mucosal tissues and peripheral blood mononuclear cells(PBMC)of AIDS patients.CD4~+ T lymphocytes were determined by immunohistochemistry method.The data were analyzed using t test.Results HIV positive rates were(1.67±1.48)% in gastric mucosa and(19.37±9.23)% in PBMC of AIDS patients who had not received highly active antiretroviral therapy(HAART).The HIV positive rates in gastric mucosa were not significantly different between AIDS patients without treatment and those treated with HAART(t=-0.996,t=-0.794,t=-0.461;P＞0.05).HIV positive rate on PBMC film preparation in patients who had received HAART for 1-4 years was (4.25±3.47)%,which was significantly lower than untreated group[(19.37±9.23)%](t=3.000,P＜0.05).The positive rate of CD4~+ T lymphocytes was(12.53±8.14)% in gastric mucosal mononuclear cells(MMC)and(19.00±9.55)% in PBMC of AIDS patient who had not received HAART.Even after received HAART for 1-4 years,the positive rate of CD4 ~+ T lymphocytes in MMC were(37.44±18.00)%,which was still lower than control group[(50.35±3.41)%](t=-4.620,P＜0.01);while the positive rate of CD4~+ T lymphocyte in PBMC was similar with that of control group(t=-2.094,P＞0.05).Conclusion The compartmentalization of HIV infection and CD4~+ T lymphocyte counts exists between gastric mucosa and peripheral blood from AIDS patients.
