To investigate the mechanisms of HIV-1 cytopathogenicity, functional biological HIV-1 clones were isolated from two infected children with high viral loads in vivo. Clone HC4 was isolated from a symptomatic child and clone GC6 8-4 was isolated from an asymptomatic child. These clones were characterized for their ability to induce syncytia, and to replicate and induce single-cell death in periph...

People with HIV infection are at increased risk for community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) skin and soft tissue infections (SSTIs). Lower CD4 T-cell counts, higher peak HIV RNA levels and epidemiological factors may be associated with increased risk but no specific immune defect has been identified. We aimed to determine the immunologic perturbations that predi...

patients and methods in the present cross-sectional study, 109 patients with established hiv infection, who visited a governmental and referral center for hiv screening in tehran (tehran west health center (twhc)) between may 2014 and july 2015 were enrolled according to the convenience sample strategy. after peripheral blood collection, isolation of plasma and peripheral blood mononuclear cell...

Tuberculosis has emerged as an epidemic fueled by the large number of individuals infected with the human immunodeficiency virus, especially those who are injecting drug users. We found a striking increase from 4- to 208-fold in p24 levels in bronchoalveolar lavage fluid from involved sites of Mycobacterium tuberculosis infection vs uninvolved sites in three HIV+ patients. We used an in vitro c...

conclusions the results of the current study showed a high rate of co-infection of m. tuberculosis and p. jirovecii in the iranian patients with hiv. as the immune system condition worsened, the probability of occurrence of pneumocystis pneumonia (pcp) increased. therefore, more specific, most rapid and sensitive tests should be utilized for diagnosis of pcp in this group of patients. results a...

background and objective: opportunistic infections are the leading cause of death among patients subjected to the human immunodeficiency virus (hiv) infection and acquired immune deficiency syndrome (aids). the aim of this study was to compare the seroprevalence of cytomegalovirus (cmv)  and toxoplasmosis infection in newly diagnosed hiv infected patients with healthy controls and it’s correlat...

BACKGROUND AND AIMS Patients with liver disease infected with the human immunodeficiency virus (HIV) exhibit accelerated progression of hepatic fibrosis and liver cirrhosis compared to uninfected individuals. We studied the effects of soluble factors secreted by HIV-infected peripheral blood mononuclear cells (PBMCs) on hepatic stellate cells (HSCs), which are central mediators of liver fibrosi...

Introduction: The human immunodeficiency virus (HIV) is a threat to global health and the need for finding new methods of antivirus research, in particular against HIV has increased in recent years. In this study, we investigated the ability of the cold atmospheric pressure plasma jet (CAPPJ) using helium to inhibit the replication of HIV virions. Methods: Single cycle replicable HIV (SCR-HIV) ...

BACKGROUND & OBJECTIVES Sexually transmitted infections (STIs) enhance the transmission of human immunodeficiency virus (HIV). Thus, screening for STIs is a routine component of primary HIV care. There are limited data for selective screening guidelines for genital mycoplasmas and Chlamydia trachomatis in HIV-infected adults. The aim of the present study was to determine the frequency of genita...

objective(s): htlv-i and hiv virus quantification is an important marker for assessment of virus activities. since there is a direct relationship between the number of virus and disease progression, htlv- i and hiv co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated.   materials and method...
