To identify virological and immunological correlates of microbial-specific immune reconstitution in children with advanced human immunodeficiency virus (HIV) infection, Candida- and tetanus-specific lymphocyte proliferation was measured in 165 children initiating a new highly active antiretroviral therapy (HAART) regimen. During the study, the proportions of children with immunity to Candida and tetanus increased from 53% to 66% and 19% to 22%, respectively. Tetanus immunity was associated with an HIV load ⩽400 RNA copies/mL and with Candida immunity. At the end of the study, 23% of the patients with baseline negative lymphocyte proliferation had tetanus immunity, and 65% had Candida immunity. Reconstitution of tetanus immunity correlated with lower end-of-study HIV loads and activated CD8+ cell percentages and higher baseline and in-study CD4+ cell percentages, but not with a gain of CD4+ cells. Reconstitution of Candida immunity showed similar trends. In conclusion, children with advanced ...

We have proposed that researchers independent of the HIV establishment should audit the Centers for Disease Controls records of AIDS cases, bearing in mind that the correlation of HIV with AIDS, upon which the case for HIV causation rests, is itself an artefact of the definition of AIDS. Since 1985, exactly the same diseases or conditions have been defined as AIDS when antibodies are present, and as non-AIDS when HIV and antibodies are absent. Independent professional groups such as the Society of Actuaries should be invited to nominate members for an independent commission to investigate the following question: How frequently do AIDS-defining diseases (or low T cell counts) occur in the absence of HIV? Until we have a definition of AIDS that is independent of HIV, the supposed correlation of HIV and AIDS is mere tautology. Other independent researchers should examine the validity of the so-called AIDS tests, especially when these tests are used in Africa and Southern Asia, to see if they ...

AIDS-defining clinical conditions (a.k.a. AIDS-defining illnesses or AIDS-defining diseases) is the list of diseases published by the Centers for Disease Control and Prevention (CDC) that are associated with AIDS, and used worldwide as a guideline for AIDS diagnosis. CDC exclusively uses the term AIDS-defining clinical conditions, but the other terms remain in common use. This list governs the US government classification of HIV disease. This is to allow the government to handle epidemic statistics and define who receives US government assistance. However, considerable variation exists in the relative risk of death following different AIDS defining clinical conditions.[further explanation needed] According to the CDC definition, a patient has AIDS if they are infected with HIV and have either: a CD4+ T-cell count below 200 cells/µL a CD4+ T-cell percentage of total lymphocytes of less than 15% or one of the defining illnesses. A patient presenting one of the above conditions but with laboratory ...
As the survival of patients with HIV increases, it is becoming increasingly important to identify those patients who are at increased risk for accelerated atherosclerosis. In the present study, we determined the relationship between intermediate end points of CVD and clinically easily obtainable anthropometric, hemodynamic, and laboratory parameters in HIV-infected patients. Our main findings are that HIV-infected patients without the MS have endothelial dysfunction similar to that of type 2 diabetic patients. The presence of the MS in HIV was associated with even more advanced functional and structural vascular abnormalities.. In the present study, 41% of the patients fulfilled the definition of the MS according to the NCEP-ATPIII guidelines. In the U.S., approximately 24% of the general population fulfills this definition (23). Elevated triglyceride levels were the most prevalent component of the MS, whereas an increased waist circumference and high fasting plasma glucose level were less ...

Cryptococcal meningitis remains the leading cause of adult meningitis in Sub-Saharan Africa. Immune Reconstitution Inflammatory Syndrome (IRIS) following anti-retroviral therapy (ART) initiation is an important complication. Here we report the first documented case of a IRIS reaction presenting as an ischemic stroke. A 38 year old newly diagnosed HIV-infected, ART naive Malawian male presented to a tertiary referral hospital in Blantyre, Malawi with a 2 week history of headache. A diagnosis of cryptococcal meningitis was made and the patient was started on 1200 mg fluconazole once daily and flucytosine 25 mg/kg four times daily as part of the Advancing Cryptococcal Treatment for Africa (ACTA) clinical trial. There was an initial clinical and microbiological response to anti-fungal treatment and anti-retroviral therapy was started at week 4. The patient re-presented 16 days later with recurrence of headache, fever, and a sudden onset of left sided weakness in the context of rapid immune reconstitution;

AU - Galimberti, Daniela. AU - Scarpini, Elio. PY - 2015/7/1. Y1 - 2015/7/1. N2 - The term Immune reconstitution inflammatory syndrome (IRIS) was originally introduced to describe the phenomenon of paradoxical clinical deterioration in HIV-infected patients despite the successful virological and immunological recovery after treatment with antiretroviral therapy. This condition has actually been described even in the central nervous system (CNS) when immunosuppressed patients experience an opportunistic infection, as a result of an aberrant response of the immune function. Since new immunosuppressant therapies for autoimmune diseases or graft rejection in transplanted patients have been established, IRIS has become much more frequent, as a consequence of sudden immunosuppressive drug removal. In Natalizumab treated ...

The exaggerated immune response to the subclinical opportunistic microorganisms or their antigens can be found in HIV-1 infected patients after receiving antiretroviral (ARV) therapy. We report a case of unmasking tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) in the HIV-1 infected patient who had no previous history of mycobacterial infection. She had tuberculosis of intestines, peritoneum and mesenteric glands within 2 months of ARV. However, her sputum acidfast bacilli stain, sputum, blood and cervical lymph node aspiration cultures for mycobacterium were negative. Her CD4 cell count increased of from 46 cells/μL at baseline before receiving ARV to 155 cells/μL at month 6 of ARV. In addition, her plasma pro-inflammatory (IFN-γ and TNF-α) and anti-inflammatory (IL-10) cytokine measurement was supported the occurrence of immune restoration reaction. Therefore, the changing in these cytokine profiles may be an important marker of developing unmasking TB-IRIS ...

In human immunodeficiency virus (HIV)-infected individuals, the proportion of circulating mononuclear cells (PBMCs) which carry HIV provirus and the number of HIV proviral sequences per infected PBMC have been matters for conjecture. Using a double polymerase chain reaction which allows the detection of single molecules of provirus and a method of quantifying the provirus molecules, we have measured provirus frequencies in infected individuals down to a level of one molecule per 10(6) PBMCs. As a general rule, only a small proportion of PBMCs contain provirus (median value of samples from 12 patients, one per 8,000 cells), and most if not all of the infected cells carry a single provirus molecule. The frequency of provirus-carrying cells correlated positively both with the progression of the disease and with the success with which virus could be isolated from the same patients by cocultivation methods. Of seven asymptomatic (Centers for Disease Control stage II) patients, all but one contained one

PY - 2000/6/10. Y1 - 2000/6/10. N2 - Cytokines and β-chemokines play an important role in the complex interaction between HIV-1 and the immune system. We studied platelet-free plasma (PFP) levels and ex vivo production of cytokines and β-chemokines at different HIV disease stages and the influence of potent protease inhibitor therapy on their production in late-stage patients. Mitogen-induced production of MIP-1α, MIP-1β, and RANTES by PBMCs was higher in HIV- infected patients than in HIV-seronegative controls. Patients with late-stage HIV infection (CD4+ cells + cells ,150/μl). Pretreatment RANTES production correlated negatively with ...

Opportunistic infections are so named because they occur in people whose immune systems are not working properly; they are opportunistic insofar as theinfectious agents take advantage of their hosts compromised immune systems and invade to cause disease.. The organisms that cause opportunistic infections are categorized as protozoa, fungi, viruses and bacteria. These organisms are found widely in nature andoften live in the human body. When the immune system is working properly, itcan control the germs. However, persons with defective immune systems are unable to fight off the growth and destructive action of these organisms withinthe body. Opportunistic infections are seldom spread to people who have normal healthy immune systems.. One of the ways the immune system can be damaged is when the person is infected by HIV. In addition, drugs used to treat cancer, and drugs used to facilitate organ transplants can also suppress the immune system.. A person infected with HIV can get an ...
The population of HIV-infected women is increasing over time, and a recent study showed that while the incidence of AIDS-defining cancers decreased by three-fold from 1991-1995 to 2001-2005, the incidence of non-AIDS-defining cancers is increasing by almost the same amount [4]. Historically, multiple studies have focused on AIDS-defining diseases, such as cervical cancer; however, there are significantly less data on HIV-infected women with vulvar cancer [16-18], and only limited reports on HIV-infected women with ovarian and endometrial cancers [19-23]. To our knowledge, there is no case series describing guideline-specific care and outcomes of HIV-infected women with gynecologic cancers. As these cancers increase, our ability to meet the standard of care and to understand the impact of standard-of-care treatment on this population is critical. In this retrospective cohort study of women with HIV infection and gynecologic cancers, we found that almost 50% of women did not receive optimal ...

Researchers found that in the combined-integrated therapy group the incidence of death was 5.4 for every 100 person-years of observation. The sequential therapy group saw an incidence of death of 12.1 for every 100 person-years of observation. After adjustment for various confounding factors, researchers found that patients in the combined-integrated therapy group had a relative risk reduction of 54%. Two and a half years into the study the data and safety monitoring committee recommended all patients be put onto the combined-integrated therapy regimen for the remainder of the study. The combined-integrated therapy group saw nearly three times the cases of immune reconstitution inflammatory syndrome, however there were no deaths resulting from this syndrome ...
HIV can eventually cause AIDS by attacking a type of white blood cell called CD4 cells [2]. These are the same cells in the immune system [3] that are supposed to protect the body from disease. When your immune system loses too many CD4 cells, you are less able to fight off infection and can develop serious illnesses, cancers [4], and neurological (nerve system) problems. These are called opportunistic infections (OIs), because they take advantage of the bodys weakened defenses.. Many viruses can be controlled by the immune system [3]. But HIV takes over CD4 cells and turns them into virus factories that produce thousands of viral copies. As the virus multiplies, it damages or kills CD4 cells, which damages the immune system and weakens the bodys defenses. OIs take an opportunity to infect you when your defenses are down. OIs can lead to hospitalization and disability, and are responsible for most of the deaths in people with AIDS (acquired immune deficiency syndrome).. The US Centers for ...
