OBJECTIVE It is well known that thoracotomy leads to several complications. In this study, effects of thoracotomy on cellular and humoral immunities have been investigated. Leukocyte counts and lymphocyte counts of 100 patients operated by thoracotomy have been determined preoperatively and on the postoperative 3rd hour, and 1st, 2nd, 3rd, 5th days. Also lymphocyte surface markers (CD3, CD4, CD...

Cryptococcus neoformans is the most common cause of laboratory-confirmed meningitis in South Africa. 1 Despite the increased coverage of antiretroviral treatment (ART), the country' s incidence of cryptococcal meningitis remains high, and in routine care settings, the disease has a case-fatality ratio of >50% at 12 weeks post-diagnosis. 2-4 Screening and pre-emptive antifungal treatment is desi...

BACKGROUND CD4 lymphocyte counts are used to monitor immune status in HIV disease. An understanding of the variability of CD4 counts which occurs in the absence of HIV infection is essential to their interpretation. The sources and degree of such variability have not been extensively studied. OBJECTIVES To establish reference ranges for CD4 counts in HIV-seronegative women and heterosexual me...

Clinical characteristics associated with bacillary angiomatosis and bacillary peliosis (BAP) in patients with human immunodeficiency virus (HIV) infection were evaluated in a case-control study; 42 case-patients and 84 controls were matched by clinical care institution. Case-patients presented with fever (temperature, > 37.8 degrees C; 93%), a median CD4 lymphocyte count of 21/mm3, cutaneous or...

To describe long-term CD4+ T-cell reconstitution after rabbit antithymocyte globulin (rATG) treatment and identify predictive factors following kidney transplantation. A single-center retrospective study analyzed lymphocyte subsets in rATG-treated kidney transplant recipients (1986-2009). 589 patients were analyzed (maximum follow-up 21 years). A comparator group (n=298) received an anti-IL-2 r...

BACKGROUND Cirrhosis of the liver can induce splenic sequestration of peripheral blood cells, recently suggested to reduce the number but not percentage of circulating CD4(+) T cells in persons uninfected with human immunodeficiency virus (HIV). We investigated whether earlier stages of liver fibrosis prior to cirrhosis were associated with discordance between CD4 count (CD4N) and CD4 percentag...

Immunophenotyping of lymphocytes is very essential for evaluation of immune system. Due to the effect of environmental factors and ethical diversity on immune system, establishment of an internal normal range of lymphocyte subsets is a necessity for each population. The aim of this study was to determine the normal range of T and B lymphocytes, and NK cells in normal Iranian adults. Two hundred...

UNLABELLED The advent of new antiretroviral drugs such as protease inhibitors has generated sensible changes in morbity and mortality in HIV-infected patients. OBJECTIVES To evaluate the impact of Highly Active Antiretroviral Therapy (HAART) on the prevalence of chronic otitis media in HIV-infected pediatric population. METHODS We analyzed medical charts of 471 children aged zero to 12 year...

Despite the impressive global results of DOTS in India, the effectiveness of DOTS for the treatment of tuberculosis in HIV-infected patients is not well known. This is an observational prospective cohort study performed in Anantapur District, Andhra Pradesh, India. The study included 1000 DOTS antituberculosis treatment (ATT) episodes and 840 person-years. CD4 lymphocyte count was below 200 cel...

OBJECTIVES We have analyzed the parameters (bacterial translocation, immune activation and regulation, presence of HCV coinfection) which could be implicated in an inappropriate immune response from individuals with chronic HIV infection. The influence of them on the evolution of CD4+ T cell count has been investigated. PATIENTS AND METHODS Seventy HIV-infected patients [monoinfected by HIV (...
