Outcomes of Universal Access to Antiretroviral Therapy (ART) in Georgia

through 2009. Of 752 patients, 76% were men, 60% were injection drug users (IDU), 59% had a history of an AIDS-defining illness, and 53% were coinfected with hepatitis C. The median baseline CD4 cell count was 141 cells/mm 3 . During followup, 152 (20%) patients died, with the majority of deaths occurring within 12 months of ART initiation. Mortality was associated with advanced immunodeficiency or the presence of incurable disease at baseline. Among patients remaining on treatment, the median CD4 gain was 216 cell/mm 3 and 86% of patients had viral load <400 copies/ml at the last clinical visit. The Georgia ART program has been successful in treating injection drug users infected with HIV

Fine-scale analysis of habitat occupancy by Kura lizard (Darevskia portschinskii) and its daughter parthenogenetic form (Darevskia dahli)

Two species of rock lizards, the parthenogenetic D. dahli and the sexually reproducing D. portschinskii, coexist in a rocky outcrop in an area of ca. 1 ha, in the vicinity of Tbilisi, Georgia; the location has been well-known since the middle 1960s. The population density of the parthenogenetic lizard is five times higher than that of the sexual breeder. We studied the distribution of active lizards in space and time over three consecutive years, during the spring and autumn activity periods, to explore spatial and temporal differences between the species on a fine spatial scale. We studied the influence of temperature, humidity, and quantitative characteristics of the surface and the distance from permanent water source on the spatial distribution of D. dahli and D. portschinskii. Darevskia portschinskii was less dependent on the distance from the water source and more evenly distributed in space and time than D. dahli. Despite potential competitive interactions, the species did not avoid each other on the microhabitat scale, suggesting that the observed ecological differences are not caused by a niche shift. More individuals of the sexual breeder than individuals of the parthenogen were found in suboptimal habitats. This feature may increase the evolutionary success of D. portschinskii in a long-term perspective

Late presentation of HIV infection in the country of Georgia: 2012-2015.

Late presentation for HIV care has important individual and population implications. The objective of this study was to explore the problem of late presentation in the country of Georgia. Data on adult persons newly diagnosed with HIV in Georgia between 2012 and 2015 were extracted from the national AIDS Health Information System. Late presenter was defined as a person diagnosed with HIV with a CD4 cell count <350 cells/mm3 or an AIDS defining illness regardless of the CD4 cell count in the six months after HIV diagnosis. Late presenter with advanced disease was defined as a person diagnosed with HIV with a CD4 cell count <200 cells/mm3 or an AIDS defining illness, regardless of CD4 cell count in the six months after HIV diagnosis. Among 2267 adults diagnosed with HIV in Georgia in 2012-2015, 1987 (87.6%) had CD4 cell count measured within 6 months of HIV diagnosis and were included in the analysis. Among them 1260 (63.4%) patients were classified as late presenters and 870 (43.8%) as late presenters with advanced disease. The proportion of late presenters declined from 71.1% in 2012 to 55.5% in 2015 (p<0.0001), while presentation late with advanced disease decreased from 56.6% in 2012 to 34.5% in 2015 (p<0.0001). Late presentation was most common among people who inject drugs (77.7%). Overall 186 patients died over the studied period. Mortality was higher both among late presenters (6.74 per 100 person-years vs. 1.08 per 100 person-years, p<0.0001) and late presenters with advanced disease (8.93 per 100 person-years vs. 1.34 per 100 person-years, p<0.0001). High prevalence of late presentation in Georgia reflects insufficiency in HIV testing services. Better testing strategies are needed to improve earlier diagnosis and disease outcomes

Etiologic agents of central nervous system infections among febrile hospitalized patients in the country of Georgia.

OBJECTIVES: There is a large spectrum of viral, bacterial, fungal, and prion pathogens that cause central nervous system (CNS) infections. As such, identification of the etiological agent requires multiple laboratory tests and accurate diagnosis requires clinical and epidemiological information. This hospital-based study aimed to determine the main causes of acute meningitis and encephalitis and enhance laboratory capacity for CNS infection diagnosis. METHODS: Children and adults patients clinically diagnosed with meningitis or encephalitis were enrolled at four reference health centers. Cerebrospinal fluid (CSF) was collected for bacterial culture, and in-house and multiplex RT-PCR testing was conducted for herpes simplex virus (HSV) types 1 and 2, mumps virus, enterovirus, varicella zoster virus (VZV), Streptococcus pneumoniae, HiB and Neisseria meningitidis. RESULTS: Out of 140 enrolled patients, the mean age was 23.9 years, and 58% were children. Bacterial or viral etiologies were determined in 51% of patients. Five Streptococcus pneumoniae cultures were isolated from CSF. Based on in-house PCR analysis, 25 patients were positive for S. pneumoniae, 6 for N. meningitidis, and 1 for H. influenzae. Viral multiplex PCR identified infections with enterovirus (n = 26), VZV (n = 4), and HSV-1 (n = 2). No patient was positive for mumps or HSV-2. CONCLUSIONS: Study findings indicate that S. pneumoniae and enteroviruses are the main etiologies in this patient cohort. The utility of molecular diagnostics for pathogen identification combined with the knowledge provided by the investigation may improve health outcomes of CNS infection cases in Georgia
