Human immunodeficiency virus infection in elderly patients

BACKGROUND: The proportion of older individuals infected with the human immunodeficiency virus (HIV) is rising. METHODS: We performed a retrospective case-control study of 58 patients more than 60 years old at the time of diagnosis of HIV infection and compared them with 232 controls (matched by CD4+ lymphocyte count). Clinical and demographic data were obtained from the Adult Spectrum of Diseases (ASD) database at the Medical Center of Louisiana. RESULTS: Patients in the older age group were more likely to be male and African American or Hispanic. The most common risk factor for acquisition of HIV infection among the patients was homosexual contact (53%). Disease staging was similar in both groups as determined by CD4+ lymphocyte counts and history of opportunistic infections. There was no difference in the use of antiretroviral therapy. In a Cox proportional hazard model and regression models, age > or = 60 years was associated with shorter survival. CONCLUSION: Patients who are older than 60 years at the time of diagnosis of HIV infection have a shorter survival than younger patients.     

Defects in cell-mediated immunity in HIV-1 infection: implications for immunotherapy and vaccine development

HIV infects a variety of cell types within the lymphon. Viral replication occurs in CD4+ T cells, B cells and antigen presenting cells. As in other viral infections, cell-mediated and antibody responses develop against infected cells. Cell-mediated effector mechanisms include cytotoxic CD8+ T cells specific for HIV core or envelope antigens and NK cells reacting with target cell bound HIV envelope protein gp120. Antibodies to gp20 are produced which mediate lymphoayte dependent cytotoxicity (ADCC) against cells carrying HIV envelope protein. HIV gp120 binds to CD4 glycoptotein both at the cell surface and within the cytoplasm of HIV infected cells. At the cell surface of CD4+ cells gp120 may induce cytolysis by T, NK cells or ADCC. Interaction between CD4 and gp120 in cytoplasm prevents CD4 transport to the plasma membrane. As surface CD4 acts as a ligand for T cell recognition of and response to antigen presenting cells, failure to express CD4 leads to functional failure of T helper cells. HIV envelope protein may also induce anti-idiotype antibodies with CD4 receptor affinity and putative blocking activity. Antigenic activation of HIV infected CD4+ T cells augments virtal replication and cytopathicity. A decline in CD4+ cell number and function usually occurs in HIV infected persons. This is characterised by failure of T cell help for CD8+ and NK and antibody responses with subsequent development of opportunistic infections. Attempts to remedy the CD4 cell defect have included biochemical, cellular and pharmocological reconstitution. To date none have shown prolonged effect. Preliminary vaccine trials in HIV seronegative persons have induced antibody responses to HIV envelope protein. Future research requires the definition of antigens capable of evoking a protective immune response to HIV without attendant immunopathology.     

Clinical applications and availability of CD4+ T cell count testing in sub-Saharan Africa

The absolute CD4+ T cell count in adults and CD4+ T cell percentage of lymphocytes (CD4%) in pediatrics compliment clinical history and physical examination to inform decisions about initiating antiretroviral therapy (ART). In addition, these immunologic markers predict host susceptibility to specific opportunistic infections, selected drug toxicities, and mortality. These benefits argue strongly for the availability of CD4+ T cell testing capacity in all settings where HIV infection is treated. Several currently available flow cytometry-based devices, and novel CD4+ T cell enumeration techniques such as the panleucogating CD4 are especially suitable for resource-constrained settings. At this time, unfortunately, the landscape of HIV care in sub-Saharan Africa is a mosaic characterized by large areas where CD4+ T cell testing capacity is limited or unavailable, and small, but growing, pockets where the capacity exists. Routine HIV quantification is currently unaffordable and unsustainable in the great majority of the region; therefore, a reliance on CD4+ T cell testing is inevitable for now. To this end, correcting the disparities in CD4+ T cell testing capacity and defining the minimum laboratory requirements for the safe use of antiretroviral drugs through well-designed clinical studies are some of the most urgent priorities of the ongoing global scale-up of ART.     

农村地区HIV/AIDS患者CD4+细胞计数与机会性感染对应关系的临床研究

目的通过随访病例,分析山东省菏泽市AIDS病毒(HIV)感染者/AIDS(AIDS)患者机会性感染发生的频率与CD4+细胞计数之间的关系,观测CD4细胞计数对机会性感染的预示作用。方法跟踪HIV/AIDS患者的随访以及CD4+检测结果,对山东省菏泽市的HIV/AIDS患者进行分析。结果在CD4+细胞计数小于200个/μl的117例HIV/AIDS患者中,有99例发生了多种机会性感染,其发生比例为84.6%,CD4+细胞计数大于300个/μl的38例患者中,有6例发生了机会性感染,其发生比例为15.8%,CD4+小于100个/μl其机会性感染率发生比例为100%。结论不同水平的CD4+细胞计数,机会性感染的发生几率不同,两者有着非常密切的关系。CD4+细胞计数越低,发生机会性感染的几率越大,因而将CD4+细胞计数作为机会性感染预防的参照指标是合理的,定期监测CD4+并作为一项常规的工作,及早预防机会性感染对提高HIV/AIDS患者的生活质量有很重要的意义。

Immunological abnormalities in human immunodeficiency virus (HIV)-infected asymptomatic homosexual men. HIV affects the immune system before CD4+ T helper cell depletion occurs.

To investigate the effect of persistent HIV infection on the immune system, we studied leukocyte functions in 14 asymptomatic homosexual men (CDC group II/III) who were at least two years seropositive, but who still had normal numbers of circulating CD4+ T cells. Compared with age-matched heterosexual men and HIV-negative homosexual men, the CD4+ and CD8+ T cells from seropositive men showed decreased proliferation to anti-CD3 monoclonal antibody and decreased CD4+ T-helper activity on PWM-driven differentiation of normal donor B cells. Monocytes of HIV-infected homosexual men showed decreased accessory function on normal T cell proliferation induced by CD3 monoclonal antibody. The most striking defect in leukocyte functional activities was observed in the B cells of HIV-infected men. B cells of 13 out of 14 seropositive men failed to produce Ig in response to PWM in the presence of adequate allogeneic T-helper activity. These findings suggest that HIV induces severe immunological abnormalities in T cells, B cells, and antigen-presenting cells early in infection before CD4+ T cell numbers start to decline. Impaired immunological function in subclinically HIV-infected patients may have clinical implications for vaccination strategies, in particular the use of live vaccines in groups with a high prevalence of HIV seropositivity.     

Screening of blood donors for idiopathic CD4+ T-lymphocytopenia

BACKGROUND: The recent recognition of idiopathic CD4+ T-lymphocytopenia (ICL) had led to concern that an unknown immunodeficiency virus may be transmissible by transfusion. STUDY DESIGN AND METHODS: To evaluate the prevalence and significance of low CD4+ values among blood donors, CD4+ data on 2030 blood donors who were negative for antibody to human immunodeficiency virus type 1 (HIV-1) were compiled. Those with CD4+ values below ICL cutoffs (< 300 CD4+ T cells/microL, or < 20% CD4+ T cells) were recalled for follow-up investigations. Serial CD4+ data on 55 homosexual men who seroconverted during prospective follow-up and data on 139 anti-HIV-1-positive blood donors initially evaluated in 1986 were reviewed as well. RESULTS: Five seronegative donors (0.25%) had absolute CD4+ counts < 300 cells per microL and/or < 20 percent. On follow-up, all five donors had immunologic findings within normal ranges, lacked HIV risk factors, and tested negative for HIV types 1 and 2 and human T-lymphotropic virus type I and II infections by antibody and polymerase chain reaction assays. Four of five donors reported transient illness shortly after their low CD4+ count donations. The median interval from HIV-1 seroconversion to an initial CD4+ value below ICL CD4+ cutoffs was 63 months for infected homosexual men. Of 139 HIV-1-infected blood donors studied 1 to 2 years after seropositive donations, 34 (24%) had CD4+ counts < 300 cells per microL and/or < 20 percent. CONCLUSION: Low CD4+ counts are rare among anti- HIV-1-negative volunteer blood donors and are generally associated with transient illnesses. If any unknown virus progresses similarly to HIV- 1, CD4+ count donor screening would be a poor surrogate for its detection.     

Correlation analysis on total lymphocyte count and CD4 count of HIV-infected patients

Objective: To determine the relationship between CD4 count and other blood indices and to explore the prediction of total lymphocyte count (TLC) for CD4 count in HIV‐infected patients. Methods: Cross‐sectional study was performed for the prediction of TLC and other indices for CD4 count, and historical cohort study was performed for the TLC changes as a surrogate for CD4 changes of patients on antiretroviral therapy (ART) to further understanding the utility of TLC changes for AIDS patients’ management. Results: In our cross‐sectional study, both TLC and white blood corpuscle count positively correlated to CD4 count, but differed in these patients. For patients on ART, the prediction of TLC for CD4 count is better than that of patient without ART. Further investigation of historical cohort study indicated that, among AIDS patients on highly active antiretroviral therapy, their TLC and haemoglobin changes also positively correlated to CD4 change, with a total correlation coefficient of 0.31 (p < 0.01) and 0.19 (p < 0.01) respectively. The prediction of TLC change for CD4 change differed each time point when patients underwent ART. Conclusions: Total lymphocyte count and its change can be used as alternative in conjunction with other indices to CD4 count and its change in the management of HIV‐infected individuals in China.
