HIV-DNA undetectability during chronic HIV infection: frequency and predictive factors.

Background: HIV-DNA is a marker of HIV reservoirs. Objectives of the study were to determine prevalence of HIV-DNA < 100 copies/106 PBMCs in blood and to identify factors associated with this in a cohort of HIV-1-infected subjects treated with ART and with undetectable viral load (VL).

Methods: This was a cross-sectional study on chronic HIV-1-infected people living with HIV (PLWH) followed up at the Department of Infectious Diseases of San Raffaele Scientific Institute on current ART without change for 12 months, with available pre-ART HIV-RNA and with undetectable VL for ≥12 months.

IVS4-14 A/G and IVS4-73 C/T polymorphisms in OLR1 gene in patients with ischemic cerebrovascular diseases.

Introduction: Oxidized low-density lipoprotein (ox-LDL) plays a key role in the processes of atherogenesis, the major cause of myocardial infarction. Increased levels of ox-LDL relate to plaque instability in human coronary atherosclerotic lesions. Moreover, ox-LDL levels show a direct correlation to the severity of coronary syndromes.

I219V polymorphism in hMLH1 gene in patients affected with ulcerative colitis.

Introduction: hMLH1 gene, lying on chromosome 3p21-23, is a key factor of the mismatch repair (MMR) complex, which amends DNA replication errors. MMR alterations are involved in the development of both hereditary and sporadic forms of colorectal carcinoma related to ulcerative colitis (UC). I219V Polymorphism is located on exon 8 of hMLH1 and provides an aminoacidic substitution of isoleucine to valine, on the protein codon 219.
