AIDS患者胃黏膜CD4~+T淋巴细胞与HIV感染关系的初步分析

目的探讨AIDS患者胃黏膜CD4^＋T淋巴细胞的丢失、重建与HIV感染的关系。方法对35例AIDS患者胃黏膜组织冰冻切片和PBMC涂片采用核酸原位杂交方法及免疫组化双重染色,观察CD4^＋T淋巴细胞的HIV感染情况。结果①高效抗逆转录病毒治疗（HAART）治疗1～4年后,AIDS患者胃黏膜单个核细胞（MMC）中CD4^＋T细胞计数仍然低于对照组[（37.44±18.00]%vs（50.35±3.41）%]（P〈0.01）;但PBMC中CD4^＋T细胞计数与对照组无显著性差异[（42.70±10.66）%vs（51.00±6.60）%]（P〉0.05）。②未治疗组与治疗〈1年组胃黏膜MMC中CD4^＋T细胞HIV阳性率无显著性差异[（2.76±1.92）%vs（1.88±1.56）%]（P〉0.05）;治疗1～4年组则明显低于未治疗组[（0.54±0.49）%vs（2.76±1.92）%（P〈0.01）;三组AIDS患者PBMC中CD4^＋T细胞HIV感染率均具有显著性差异[（19.44±8.17）%vs（9.76±6.98）%vs（4.95±8.26）%]（P〈0.05）。结论相对于外周血,AIDS患者胃黏膜免疫重建可能是不完全的。AIDS患者胃黏膜CD4^＋T细胞HIV感染在胃黏膜CD4^＋T细胞的丢失与重建延迟过程中可能并非发挥主要的作用。     

HIV、HCV复合感染患者HAART治疗后CD4＋细胞计数和HCV RNA变化的研究

目的了解河南省某县HIV感染者HIV、HCV复合感染状况以及高效抗逆转录病毒治疗（HAART）后CD4＋细胞计数和HCV RNA的变化。方法测定HIV感染者HCV—IgG、CD4＋细胞计数、血浆HIV和HCV病毒栽量。采用单因素方差分析比较应用HAART后CIM＋细胞计数和HCV RNA的变化。结果228名HIV感染者中，HCV—IgG阳性率88、6％（202／228）。在HAART超过6个月且HCV—IgG阳性的病人中，HIV RNA阴性（B组）的CD4＋细胞计数显著高于HIV RNA阳性的患者（A组）（P=0．020）；而两组的HCV RNA病毒栽量差异无统计学意义（P=0．749）。结论河南地区HIV、HCV复合感染在血液传播的HIV感染者中普遍存在。经HAART治疗的患者随着血浆HIV RNA转阴，CD4＋细胞计数显著升高，但血浆中HCV RNA的含量无显著变化。     

Secondary syphilis-related oral ulcers: report of four cases

Establishing a diagnosis of syphilis, whatever the stage of the disease, can be difficult because syphilis is a great mimic in clinical morphology and histology. Many patients infected with venereal diseases have oral manifestations, but very few dentists and physicians have the proper experience to diagnose syphilis or other STDs from oral lesions. Oral secondary syphilis appears to be very uncommon, and few cases have been reported over the recent past. We present 4 patients who developed secondary syphilis-related oral lesions of moist ulcers, irregular linear erosions termed 'snail-track' ulcers, or erythematous mucous patches on the labial mucosa, buccal mucosa, palate, or tongue. Concurrent human immunodeficiency virus (HIV) infection was diagnosed in 1 patient. The histological examination in 2 patients showed dense subepithelial inflammatory cell infiltration comprised predominantly of plasma cells, and it was of practical help in the diagnosis of syphilis. The diagnostic value of a histological examination, serologic tests, and treatment of syphilis are discussed. Obviously, coinfection with HIV will complicate the clinical presentation, diagnosis, and management of syphilis. Concurrent HIV infection should be considered in any patient with a sexually transmitted disease including syphilis.     

Orocutaneous Manifestations as Markers of Disease Progression in HIV Infection in Indian Setting

CD4, CD8 and absolute lymphocyte counts (ALC) were carried out by flowcytometry in 36 HIV-infected cases with various orocutaneous manifestations, 50 asymptomatic HIV infected individuals and 50 HIV-negative controls. Average CD4 counts and CD4 : CD8 ratio in symptomatic HIV-infected cases were found to be 245.39/cmm and 0.27 respectively, significantly lower than that of HIV-infected asymptomatic individuals (622.4 and 0.45 respectively) and HIV-negative controls (798.81 and 1.03 respectively). Patients with one (77.78%), two (19.44%) and three (2.78%) orocutaneous manifestations had average CD4 counts of280.25, 131.3 and 68/cmm respectively. All the 7 cases with oral mucosal candidiasis had CD4 counts lower than 200/cmm (average 105.28/cmm), thus fulfilling AIDS-defining criteria. Although 6 (85.71%) of the 7 cases had CD4 counts less than 200, Herpes zoster should not be considered as an AIDS-defining illness, as the HIV-infected who had had H zoster in the past had higher CD4 count (average 299/cmm). Dermatoses like seborrhoeic dermatitis and lichen planus, and some infections and infestations like scabies, bacillary angiomatosis, human papilloma virus infection, molluscum contagiosum and dermatophytosis cannot be considered as AIDS-defining illnesses per se.Key Words: CD4 counts, HIV infection, Orocutaneous manifestations     

HIV／AIDS患者CD4^＋、CD8^＋及WBC检测分析

目的分析HIV／AIDS患者外周血T辅助细胞（CD4^＋）、T抑制细胞（CD8^＋）和白细胞（WBC）检测结果。方法CD4^＋和CD8^＋计数通过免疫荧光标记,采用流式细胞仪检测;白细胞（WBC）计数采用全自动细胞分析仪检测。结果118例HIV／AIDS住院患者,WBC降低组（3．00±0．61）×10^9/L的CD4^＋和CD8^＋分别为（68．60±38．98）个/ul和（266．89±126．52）处／ul,WBC正常组（7．13±5．12）×10^9／L的CD4＋和CD8＋分别为（104．39±61．37）个/ul和（380．17±134．06）个/ul,两者差异有统计学意义（t1＝5．78,守3．62,t3=5．35,P均〈0．01）;两组别CD4^＋／CD8^＋比值比较均呈有统计学意义（P〈0．05）。结论HIV,AIDS患者在发病过程中与CD4^＋、CD4^＋／CD8^＋、WBC有密切相关,建议HIV感染者尽早进行医学咨询并做CD4^＋、CD8^＋和血常规的检测,以了解病情的进展及进行抗病毒治疗。     

急性HIV感染者HLA-A、B携带Bw4簇对CD4 T细胞计数、病毒载量的影响

目的 观察急性人类免疫缺陷病毒(HIV)感染者人类白细胞抗原(HLA)A、HLA-B携带Bw4簇对其CD4 T细胞计数、病毒载量的影响.方法 用序列特异性引物-聚合酶链反应(SSP-PCR)对2006-2009年北京及其周边地区的95例急性HIV感染者的HLA-A、B等位基因分型,检测CD4 T细胞计数和病毒载量,分析HLA-A、B携带Bw4对急性HIV感染者CD4 T细胞计数、病毒载量的影响.结果 (1)在95例急性HIV感染者中,HLA-A、HLA-B携带Bw4分别占32.6%(31/95)、60.0%(57/95).HLA-B携带Bw4/4、Bw4/6、Bw6/6的感染者分别为21.1%(20/95)、38.9%(37/95)、40.0%(38/95).(2)与CD4 T细胞计数＜500个/μl患者比较,CD4 T细胞计数≥500个/μl患者携带Bw4数量更多(平均秩次:56.7比41.6,U=749.5,P＜0.01).最少的感染者是HLA-A、B携带3个Bw4且CD4 T细胞＜500个/μl(1例),其次是HLA-A、B携带0或3个Bw4且CD4 T细胞≥500个/μl(均为7例,x2=12.6,P＜0.01).(3)HLA-A、B携带0或1个Bw4的感染者其CD4 T细胞计数均低于携带3个Bw4的感染者(中位数:430、425个/μl比651个/μl),而病毒载量均高于携带3个Bw4的感染者(对数值,中位数:4.48、4.40比3.43,均P＜0.05).但是HLA-A、B携带2个或3个Bw4的感染者CD4T细胞计数和病毒载量差异均无统计学意义(均P＞0.05).(4)不考虑HLA-A是否携带Bw4,HLA-B携带Bw4/4纯合子的感染者其CD4 T细胞计数(中位数:538个/μl))显著高于HLA-B携带Bw4/6或Bw6/6的感染者(433、427个/μl)而病毒载量(对数值,中位数:3.53)显著低于HLA-B携带Bw4/6或Bw6/6的感染者(4.29、4.48,均P＜0.05).而不考虑HLA-B是否携带Bw4,HLA-A携带Bw4与不携带Bw4的感染者比较,CD4 T细胞计数和病毒载量差异无统计意义(P＞0.05).结论 Bw4可能与HIV感染者高CD4 T细胞计数、低病毒载量有关,并且可能是HLA-B携带Bw4/4纯合子起作用,从而延缓疾病进展.     

Ocular manifestations in 321 male consecutive cases of human immunodeficiency virus infection/acquired immunodeficiency syndrome at an HIV-referral centre

Background

Most studies on the ocular manifestations of human immunodeficiency virus (HIV) infection are on cases of acquired immunodeficiency syndrome (AIDS), not including asymptomatic carriers of HIV. With this background, we proceeded to study all the HIV-infected individuals attending our centre, with the aim:a. To study the ocular manifestations of HIV.b. To correlate those manifestations with the CD4+ T-lymphocyte counts.c. To compare our findings with other studies.

Method

A cross-sectional study involving a detailed ocular examination of 321 cases of HIV/AIDS was done. Automated perimetry, digital fundus photography and fundus fluorescein angiography were done for relevant cases. The last 125 cases were subjected to Schirmer's test and tear film break-up time.

Results

We studied 321 male HIV cases (642 eyes), with a mean age of 36.78 years, mean CD4+ count of 276.54 cells/μL, 78.82% of them being on anti-retroviral therapy. Ocular manifestations were seen in 87 out of 321 cases, 72.41% of them being asymptomatic carriers of HIV. The ocular findings seen were conjunctival microvasculopathy, molluscum contagio-sum, dry eye, neuro-ophthalmic manifestations, anterior uveitis, posterior uveitis, and HIV retinopathy, only the last three of which had a significant association with CD4+ counts. The overall prevalence of ocular lesions also had a significant association with CD4+ counts.

Conclusion

Ocular manifestations are common in asymptomatic carriers of HIV. Anterior uveitis, posterior uveitis and HIV retinopathy have a significant association with CD4+ counts and are reliable indicators of low CD4+ count.     

Reduction of CD55 and/or CD59 in red blood cells of patients with HIV infection.

BACKGROUND: Anemia is a common feature in HIV infection. An increased sensitivity of lymphocytes from HIV patients to lysis by complement has been correlated with a decreased expression of CD55 and CD59 in their surface. The aim of this study was to evaluate CD55/CD59 presence in red cells of HIV patients and explore possible correlations with clinical parameters. MATERIAL/METHODS: CD55/CD59 expression was evaluated in erythrocytes of 37 patients (30M/7F, median age: 39 years) with HIV infection (25 also having hemophilia), 121 controls, and 8 PNH patients using the sephacryl-gel microtyping system. Ham and sucrose tests were also performed. RESULTS: Anemia was present in 14/37 (37%) HIV patients. Interestingly, all HIV patients had deficient CD55 and/or CD59 erythrocytes: 8 (21%) for both CD55 andCD59 and 29 (78%) isolated CD55 and/or CD59 negativity. Deficient erythrocytes did not account for more than 10% of the total in the vast majority of patients. In controls, only 2 (1%) had red cells with double CD55/CD59 negativity and 3 (2%) had isolated deficiency. All PNH patients had a simultaneous CD55/CD59 deficiency. Positive Ham and sucrose tests were found only in PNH. There was no correlation between the presence of deficient CD55/CD59 erythrocytes and anemia, hemolysis, antiretroviral therapy, CD4+ counts, viral load, or concomitant hepatitis C infection in HIV patients. CONCLUSIONS: This study provides evidence supporting the presence of erythrocytes with CD55 and/or CD59 deficiency in HIV. Further studies using molecular techniques will be required to clarify the exact role of this deficiency in HIV patients.     

CD4+ T-lymphopenia in HIV negative tuberculous patients at King Khalid University Hospital in Riyadh,Saudi Arabia

Tuberculosis (Tb) is a chronic infectious disease in which the cellular immunity (specifically CD4+ and CD8 lymphocytes) provides the most important defense in controlling infection. CD4 lymphopenia is a well-defined risk factor for the development of active tuberculosis in patients infected with Human Immunodeficiency Virus. In HIV - negative patients, CD4 and CD8 cell count suppression has been associated with Tb infection. Our study was designed to determine the baseline and post-treatment values of CD4 and CD8 in HIV negative patients diagnosed with active Tb in Saudi Arabian patients. We recruited twenty-eight, non-HIV patients with tuberculosis for the study group comprising 16 males and 12 females with either disseminated or localized active Tb infection. Two control groups were selected one of twenty-one matched healthy controls and the second of forty-two subjects from pool of controls of an ongoing study in same population for normal CD4 and CD8 counts. The baseline pre-treatment CD4 and CD8 counts in the study group were significantly lower than either control group. Specifically the mean ± SD of CD4 counts were 556.79 ± 298.81 in the study group vs 1,132.38 ± 259.90 in control group 1 and 1,424.38 ± 870.98 in control group 2 (p 0.000). Likewise the CD8 counts in the study group were 1,136.00 ± 512.06 vs. 1,461.90 ± 367.02 in control group 1 and 1,495.90 ± 565.32 in control group 2 (p 0.000) respectively. After treatment of tuberculosis, the study patients experienced a significant increase in their mean ± SD CD4 and CD8 cell counts, from 556.79 ± 297.81 to 954.29 ± 210.90 for CD4 cells (p 0.005) and 1136.00 ± 512.06 to 1,316.54 ± 286.17 for CD8 cells (p 0.002). Analysis of study patients with disseminated disease found significantly lower CD4 cells (but not lower CD8 cells) compared to study patients with localized disease, both at baseline and after treatment. The mean ± SD baseline CD4 cells were 247.60 ± 187.80 with disseminated vs 728.56 ± 186.32 for localized disease (p = 0.000) which rose to 842.30 ± 93.55 vs 1016.50 ± 233.51 (p = 0.033) respectively. We conclude that tuberculosis may be associated with CD4 and CD8 lymphopenia even in patients without human immunodeficiency virus infection, there was the tendency of recovery towards normality especially of the CD4 and CD8 counts after treatment, and that disseminated disease is associated specifically with profound CD4 lymphopenia.     

Rates of disease progression by baseline CD4 cell count and viral load after initiating triple-drug therapy.

CONTEXT: Current recommendations for initiation of antiretroviral therapy in patients infected with human immunodeficiency virus type 1 (HIV) are based on CD4 T-lymphocyte cell counts and plasma HIV RNA levels. The relative prognostic value of each marker following initiation of therapy has not been fully characterized. OBJECTIVE: To describe rates of disease progression to death and AIDS or death among patients starting triple-drug antiretroviral therapy, stratified by baseline CD4 cell count and HIV RNA levels. DESIGN, SETTING, AND PARTICIPANTS: Population-based analysis of 1219 antiretroviral therapy-naive HIV-positive men and women aged 18 years or older in British Columbia who initiated triple-drug therapy between August 1, 1996, and September 30, 1999. MAIN OUTCOME MEASURE: Cumulative mortality rates from the initiation of triple-drug antiretroviral therapy to September 30, 2000, determined using various CD4 cell and plasma HIV RNA thresholds. RESULTS: As of September 30, 2000, 82 patients had died of AIDS-related causes, for a crude AIDS-related mortality rate of 6.7%. The product limit estimate (SE) of the cumulative mortality rate at 12 months was 2.9% (0.5%). In univariate analyses, a prior diagnosis of acquired immunodeficiency syndrome (AIDS), CD4 cell count, use of protease inhibitors, and HIV RNA level were associated with mortality. There was no difference in mortality by age or sex. Only CD4 cell count remained statistically significant in the multivariate analysis. After controlling for AIDS, protease inhibitor use, and plasma HIV RNA level at baseline, patients with CD4 cell counts of less than 50/microL were 6.67 (95% confidence interval [CI], 3.61-12.34) times and those with counts of 50/microL to 199/microL were 3.41 (95% CI, 1.93-6.03) times more likely to die than those with counts of at least 200/microL. CONCLUSION: Our data demonstrate uniformly low rates of disease progression to death and AIDS or death among patients starting antiretroviral therapy with CD4 cell counts of at least 200/microL. In our study, disease progression to death and AIDS or death was clustered among patients starting therapy with CD4 cell counts less than 200/microL.

CD4T淋巴细胞计数与HIV感染者手术风险评估

目的根据CD4T淋巴细胞计数评估HIV感染者手术并发症发生率的关系。方法回顾性分析上海公共卫生临床中心2009年1月-2010年3月收治的60例HIV阳性手术患者,按照不同CIMT淋巴细胞计数分为A（CIM〈100cell／μl）、B（100cell／μl〈CD4〈300cell／μl）和C（C134〉300cell／μl）三组。结果三组间术前白蛋白、血红蛋白、白细胞数量差异无统计学意义;A组术前HIV感染相关性并发症发生率为40％（6／15）,术后甲级愈合率为66．7％（10／15）,乙级愈合率为33．3％（5／15）,手术死亡率为13．3％（2／15）;其余二组Ⅰ类和Ⅱ类手术切口术前均无感染相关性并发症。术后伤口愈合均达到甲级,无手术死亡。结论CD4T淋巴细胞计数对HIV阳性患者的手术风险评估有重要意义．当CD4T淋巴细胞计数〈100cell／μl时手术死亡率和感染性并发症发生率明显增加。     

云南省玉溪市未抗病毒治疗HIV/AIDS患者T淋巴细胞计数自然变化

目的 探讨玉溪市未抗病毒治疗HIV感染者/艾滋病患者（HIV/AIDS）T淋巴细胞计数（CD3、CD4和CD8）自然变化,了解其艾滋病自然病程。方法 收集2006—2014年间玉溪市新报告HIV/AIDS未抗病毒治疗资料,获取首次与末次CD3、CD4和CD8数据,描述并比较CD3、CD4和CD8自然变化速率。结果 CD3、CD4和CD8月均自然变化速率分别为4.14个/μL、-2.13个/μL和7.57个/μL。其中886例（62.66%）CD4末次较首次低,表现为自然下降。首次CD4越高,其月均下降越快,而首次CD4较低,其月均下降较慢甚至出现上升,差异有统计学意义（P<0.05）。男性、汉族、≥50岁者、传播途径为注射吸毒者月均CD4自然变化下降速率较快,而女性、少数民族、50岁以下者、传播途径为性传播者CD3、CD8上升速率较快,差异均有统计学意义（P均<0.05）。结论 玉溪市HIV/AIDS CD3、CD4和CD8自然变化总体平缓,但仍然有部分HIV/AIDS的CD4下降较快,或是CD3 、CD8上升较快,需对该类人群加强随访,及时介入抗病毒治疗。     

Ocular manifestations in 321 male consecutive cases of human immunodeficiency virus infection/acquired immunodeficiency syndrome at an HIV-referral centre

Results

We studied 321 male HIV cases (642 eyes), with a mean age of 36.78 years, mean CD4+ count of 276.54 cells/μL, 78.82% of them being on anti-retroviral therapy. Ocular manifestations were seen in 87 out of 321 cases, 72.41% of them being asymptomatic carriers of HIV. The ocular findings seen were conjunctival microvasculopathy, molluscum contagio-sum, dry eye, neuro-ophthalmic manifestations, anterior uveitis, posterior uveitis, and HIV retinopathy, only the last three of which had a significant association with CD4+ counts. The overall prevalence of ocular lesions also had a significant association with CD4+ counts.

Conclusion

Ocular manifestations are common in asymptomatic carriers of HIV. Anterior uveitis, posterior uveitis and HIV retinopathy have a significant association with CD4+ counts and are reliable indicators of low CD4+ count.     

脂多糖对干燥综合征患者唇腺上皮细胞表达TLR4及CD14的影响

目的 探讨LPS-TLR4-CD14信号传导通路在干燥综合征(sjogren's syndrome,SS)发病机制中的作用。 方法 选择解放军第285医院风湿科2015年3月-2016年3月收治SS患者7例为研究组;另5例排除SS诊断,且无其他疾病的作为对照组。①取患者唇腺组织进行体外培养,一周后采用抗细胞角蛋白19的单克隆抗体PAP法对新生细胞和唇腺组织细胞进行染色,以鉴定新生细胞来源。②分别于培养成功的新生细胞PSS组和对照组加入浓度为1 μg/ml的内毒素(lipopolysaccharide,LPS),在继续培养后1、8、12、24、48、72 h时间点提取细胞总RNA,采用RT-PCR法分别检测不同时间点TLR4、CD14 mRNA的表达。③对新生细胞pSS组分别加入浓度为1、10、100、103、104、105 ng/ml的LPS,对照组不加LPS,继续培养24 h后分别检测TLR4和CD14 mRNA表达。 结果 ①结果显示新生细胞和唇腺组织中导管上皮细胞染色为阳性反应,唇腺组织中的淋巴细胞、腺泡细胞呈阴性反应,证明本次培养的新生细胞来源于唇腺组织的导管上皮细胞。②在新生细胞中加入LPS,作用1 h后TLR4和CD14 mRNA表达增强,分别于8、12 h后达高峰期,作用72 h后明显下降。③浓度为1 ng/ml的LPS即可引起PSS组新生细胞TLR4和CD14 mRNA表达显著增高,随着LPS浓度的增高,TLR4和CD14 mRNA表达持续升高,当LPS浓度达到104 ng/ml以上时,TLR4和CD14 mRNA表达呈平台期,变化不显著。 结论 经LPS刺激后,唇腺导管上皮细胞高表达TLR4和CD14 mRNA,且反应在一定范围内呈时间、浓度依赖性,由此推断LPS-TLR4-CD14信号转导通路参与了SS的发病机制,进而揭示感染与SS发病有关。
