Detection of Epstein Barr virus in an hepatic leiomyomatous neoplasm in an adult human immunodeficiency virus 1-infected patient

We report the first case of a human immunodeficiency virus (HIV)-related primary hepatic leiomyoma in an adult patient. The diagnosis was made at autopsy and confirmed by immunohistochemistry. Epstein Barr virus (EBV) was identified in tumour cells by in situ hybridization. Review of the literature revealed 13 cases of visceral myogenic tumours occuring in acquired immunodeficiency syndrome children, and only 2 cases in adults. One was a spinal epidural leiomyoma, the other multiple smooth muscle tumours of the colon and adrenal gland. This is the first report of EBV in smooth muscle neoplastic cells in an HIV-infected adult patient.     

肠道淋巴瘤与EB病毒相关性研究

目的：探讨EB病毒（Epstein-Barr virus,EBV)感染在肠道淋巴瘤发病中的意义。方法：采用EBV的DNA原位杂交及S－P法免疫组化技术（第一抗体为EBV、CD3、CD20、CD43、CD45、CD45RO、CD74等），观察24例肠道淋巴瘤患者（8例肠病相关T细胞淋巴瘤、16例黏膜相关淋巴组织B细胞淋巴瘤）EBV感染情况。以20例慢性结肠炎作为对照。结果：患者年龄21－92岁（平均52．8岁），男女之比为3．8：1。临床上均以腹痛、腹胀或便血就诊。组织病理学：T细胞淋巴瘤细胞多形性、核大，不规则，嗜血管性及大片坏死；B细胞淋巴瘤细胞中等大小，多呈圆形、椭圆形、胞质较少淡染，核稍大，核分裂象多见，可见“淋巴上皮病变”。24例淋巴瘤中检出（原位杂交及免疫组化）EBV－DNA 14例（检出率为58．3％），其中T细胞淋巴瘤EBV的检出率为75％，B细胞淋巴瘤EBV的检出率为50％（P＜0．01）。结论：肠道淋巴瘤的发生与EBV的感染有明显的相关性。     

鼻咽癌患者鼻咽组织和血清中EBV检测

目的：比较血清爱泼斯坦－巴尔病毒（ＥＢＶ）抗体滴定度测定与癌组织ＥＢＶ基因组检测对鼻咽癌（ＮＰＣ）的诊断价值。方法：１４６例患者采用双盲法测定血清ＥＢＶ－ＶＣＡ－ＩｇＡ,ＥＢＶ－ＥＡ－ＩｇＡ和活检组织ＥＢＶ－ＤＮＡ（ＰＣＲ）。全组病例按活检病理检查结果分析：ＮＰＣ组,非ＮＰＣ组（对照组）。结果：ＮＰＣ组中ＥＢＶ－ＤＮＡ（ＰＣＲ）,ＥＢＶ－ＶＣＡ－ＩｇＡ和ＥＢＶ－ＥＡ－ＩｇＡ的阳性率分别为９０．８％     

淋巴组织增生性疾病组织中EB病毒的原位杂交检测

目的探讨ＥＢ病毒与我国各类淋巴组织增生性疾病的关系。方法以ＥＢ病毒ＬＭＰ基因为探针,对２１４例淋巴组织增生性疾病组织中ＥＢ病毒进行原位杂交检测,并用ＳＹＳＴＡＴ软件对实验结果进行分析。结果霍奇金淋巴瘤（ＨＤ）、非霍奇金淋巴瘤（ＮＨＬ）、淋巴组织良性增生（ＢＬＰ）组织中ＥＢ病毒阳性率分别为３０．０％（１５／５０）,１４．０％（１８／１２９）及２．９％（１／３５）。在ＮＨＬ中,高度恶性（ＨＮＨＬ）、中度恶性（ＭＮＨＬ）及低度恶性（ＬＮＨＬ）ＥＢ病毒阳性率分别为２８．１％（９／３２）、１０．５％（９／８４）及０％（０／９）。ＨＤ与ＨＮＨＬ间ＥＢ病毒阳性率均显著高于ＢＬＰ（Ｐ＜０．０１,Ｐ＜０．０５）,ＭＮＨＬ和ＬＮＨＬ与ＢＬＰ间ＥＢ病毒阳性率差异无显著性（Ｐ＞０．０５）。结论ＥＢ病毒与ＨＤ及ＨＮＨＬ的发生有关,而与ＭＮＨＬ及ＬＮＨＬ的发生关系不大。     

EB病毒与原发性鼻咽部B细胞性淋巴瘤有关与继发性者无关

目的：对１９ 例鼻咽部Ｂ细胞性恶性淋巴瘤与ＥＢ 病毒（ＥｐｓｔｅｉｎＢａｒｒ ｖｉｒｕｓ,ＥＢＶ） 感染的相关性进行研究。方法：利用免疫组织化学及原位杂交方法对ＥＢＶ 进行检测,并用免疫组化及原位杂交双染法标记肿瘤细胞,以鉴定ＥＢＶ阳性的细胞为Ｂ淋巴瘤细胞。结果：ＥＢＶ 编码的小ｍ ＲＮＡ探针（ＥＢＥＲ） 原位杂交显示,８ 例原发性鼻咽部Ｂ细胞性恶性淋巴瘤中３ 例绝大多数肿瘤细胞呈阳性表达,１ 例潜在性膜蛋白１（ｌａｔｅｎｔ ｍｅｍｂｒａｎｅ ｐｒｏｔｅｉｎ １,ＬＭＰ１）阳性。而１１ 例继发性鼻咽部Ｂ细胞性恶性淋巴瘤ＥＢＥＲ全部为阴性。全部病例进行了ＬＭＰ１ 检测,除１ 例原发者,全部阴性。利用ＥＢＥＲＩＳＨ（ＥＢＥＲ原位杂交） 和免疫组化ＣＤ 标记物进行双标记染色证实,ＥＢＥＲ 和ＬＭＰ１阳性细胞为ＣＤ２０ 阳性,ＣＤ４５ＲＯ 阴性。鼻咽部原发性Ｂ细胞性恶性淋巴瘤ＥＢＶ 表达４／８ ,而继发者为０／１１。结论：ＥＢＶ 与鼻咽部原发性Ｂ细胞恶性淋巴瘤有较高的相关性,而与继发性者无关。     

B‐Cell lymphoproliferative disorder not associated with Epstein‐Barr Virus in a child with relapsed acute lymphoblastic leukemia

Lymphoproliferative disorder (LPD) is described in only a few children receiving chemotherapy for cancer. In all of them, an association between LPD and EBV (Epstein‐Barr Virus) was found. We report on a patient who developed LPD not associated with EBV while receiving chemotherapy for relapsed acute lymphoblastic leukemia (ALL). Despite discontinuation of chemotherapy, administration of intravenous immunoglobulins and surgery the patient died. Growing experience with this disorder may allow better treatment options in the future and will show whether LPD not associated with EBV requires different therapeutic strategies.

Correlation between Epstein Barr virus antibodies, serum IgE and atopic disease

It is currently accepted that vinil infections may influence the development of atopy. In the present study we evaluated serum IgE levels as well as the prevalence of symptom-, indicative of utopic disease and EBV antibodies in 353 children aged from I month to 19 years. Antibodies against EBV were detected by immunofluorescence. IgE levels in serum were measured by en/. yme imimmoassay. Dividing ihe study population according to EBV seropositivity and age, we noted that the prevalence of high IgE levels (> 2 s. d.) was, in total, more frequent in the EBV negative (32. 9%) than in the positive subjects (27. 6%). Interestingly, this higher prevalence was found only in the groups aged under six, especially in the 7 to 29 month group, where it was statistically significant (p=0.037), whereas in the 6-19 year group the situation was reversed. Furthermore, selecting only the atopic children younger than 3 years of age with high IgE levels and clinical symptoms of atopy (wheezing and/or dermatitis) it was possible to demonstrate lower EBV seropositivity compared with the normal IgE controls for each group, even though these differences were not statistically significant. In conclusion, the results of our study suggest that, in our selected population, EBV infection in the first years of life is associated with a lower prevalence of high IgE levels.
