OBJECTIVES HIV prevalence among older people is on the increase. The aim of this study was to evaluate the epidemiological and clinical features at diagnosis and survival of older patients. METHODS This was a retrospective analysis of the data of 558 newly diagnosed antiretroviral-naïve patients between January 1998 and December 2008. Patients were(More)
The aim of the study was to evaluate the penetration of linezolid into cerebrospinal fluid (CSF) and brain tissue after a single i.v. dose of 600 mg. The penetration of linezolid into cerebrospinal fluid and brain tissue was studied in 18 patients undergoing a neurosurgical procedure. Linezolid 600 mg i.v. was given with the induction of anesthesia. Mean(More)
OBJECTIVES To determine the contribution of transmission clusters to transmitted drug resistance (TDR) in newly diagnosed antiretroviral-naive HIV-1-infected patients in Northern Greece during 2000-07. METHODS The prevalence of TDR was estimated in 369 individuals who were diagnosed with HIV-1 infection in the period 2000-07 at the National AIDS Reference(More)
We conducted a retrospective study on the prevalence and correlates of transmitted drug resistance among newly-diagnosed antiretroviral naive human immunodeficiency virus (HIV) patients in Northern Greece, during the period 2009-11. Transmitted drug resistance was documented in 21.8% of patients enrolled, affecting approximately 40% of subtype A(More)
BACKGROUND The aim of our study was to assess the extent of late presentation for HIV care in Northern Greece during the period 2000 to 2010 and to explore correlations aiming to provide guidance for future interventions. METHODS HIV-positive patients with no prior history of HIV care at presentation and with a CD4 T cell count within three months from(More)
Plasmablastic lymphoma (PBL) of the oral cavity is a rare form of non-Hodgkin lymphoma that is most frequently met in human immunodeficiency (HIV) positive patients. Only a few cases have been reported worldwide since 1997. This clinical entity may escape detection due to its unusual immunophenotype and rare occurrence. Our aim is to present two cases with(More)
Although there is evidence that HCV progresses rapidly in HIV/HCV coinfected patients in comparison with HCV monoinfected, the HIV-, HCV- and host/genetic-related factors, as well as the exact mechanisms implicated in this process are not fully elucidated. Furthermore, cure of HCV in those coinfected seems possible with the new antiviral drugs, but high(More)
BACKGROUND The incidence of infectious spondylodiscitis has been increasing over the last few years. This reflects the expanding elderly and immunocompromised populations and the rising implementation of invasive spinal procedures. Infection may be inoculated into the disc space directly during invasive spinal procedures. Osteomyelitis caused by(More)
