Objective To investigate the pathological types and features of lymph nodes in human immunodeficiency virus(HIV)/acquired immune deficiency syndrome(AIDS)patients with superficial lymphadenectasis.Methods The tissues of lymph nodes were obtained from 151 HIV/AIDS patients with superficial lymphadenectasis for pathological examination.The pathological results were observed by light microscope after Hematoxylin-Eosin(HE),acid-fast,periodic acid-Schiff (PAS),and digested-PAS(D-PAS)staining.The pathological results of lymph nodes were described and the correlation between pathological changes and CD4+T lymphocyte count was analyzed.Chisquare test was used for the statistic analysis.Results The benign lesions were found in 145 patients (96.0%),while the malignant tumors were found in 6 patients(4.0%).The pathological findings in the 151 HIV/AIDS patients included tuberculosis(72 patients),lymph node reactive hyperplasia(34patients),lymphatic fungal infections(23 patients,including penicillium diseases in 19 cases),AIDSrelated lymphadenectasis(14 cases),non-Hodgkin lymphoma(5 cases),benign fibrous histiocytoma (1 case).In addition,there were 83 patients(55.0%)with CD4+T lymphocyte count lower than 100×106/L.The frequency of penicillium diseases was higher in patients with lower CD4+T lymphocyte count(x2=7.757,P=0.021).Conclusions The major reasons for superficial lymphadenectasis in HIV/AIDS patients are infectious diseases,such as tuberculosis and fungal infections,which are common in patients with lower CD4+T lymphocyte counts.Non-Hodgkin lymphoma is the most common malignant tumor in this patient population.

Objective To investigate the problem of adverse effects in common AIDS patients and AIDS patients with tuberculosis after highly active antiretroviral therapy (HAART). Methods The case group was composed of 106 patients with both AIDS and tuberculosis. The control group was composed of 134 common AIDS patients. The rates of adverse effects and the increase of CD4 + T cell count in those groups after first year HAART were observed and compared. Results The rates of adverse effects in the case group was 36. 8% ,which was more than that in the control group (26. 9%), but the difference was not significantly different(x2 =2.715, P =0. 099). The count of CD4+ T cell in most of the patients was increased after HAART (P ＜ 0. 01). The increase of CD4 + T cell count in the case group [(147.2 ±137.6)/μl] was higher that in the control group[(142. 1 ± 127. 0)/μl after six months HAART vs. (166. 5±133. 1)/μl in case group], and it was lower than that in control group after nine months HAART [(172.7±107.5)/μl], however the difference was not significant(P ＞0.05). Conclusions HAARTcould reconstruct the immunition of AIDS patients. The increase of CD4 + T cell count did not show significant difference between common AIDS patients and AIDS patients with tuberculosis after HAART. AIDS patients with tuberculosis might not increase the risk of development of adverse effects during HAART.
