The incidence of lead (Pb) poisoning in children in Georgia has been identified as a major health concern, with a recent national survey identifying that 41% of children aged 2–7 years had blood lead concentrations (BLCs) greater than the blood lead reference value (BLRV) of ≥5 µg dL−1. This study collected samples of blood, spices, paint, soil, dust, flour, tea, toys, milk, and water from 36 households in Georgia where a child had previously been identified as having a BLC > BLRV. The Pb concentrations of these samples were determined and compared to Georgian reference values. Samples from 3 households were analysed for their Pb isotope composition. The Pb isotope composition of the environmental and blood samples were compared to identify the most likely source(s) of Pb exposure. This approach identified that some spice and dust samples were the likely sources of Pb in the blood in these cases. Importantly, some soil, paint, and dust sources with high Pb concentrations could be discounted as contributing to blood Pb based on their distinct isotope composition. The data presented demonstrate the significant contribution that Pb surveillance and Pb isotope ratio analyses can make to managing Pb exposure in regions where high BLCs are identified.

In recent years, reports of lead contamination have dramatically increased in Georgia. Given concerns about the exposure of children to lead (Pb), the National Multiple Indicator Cluster Survey (MICS-2018) included a blood sampling component. The results showed that 41% of the children that participated had blood Pb levels (BLL) ≥ 5 µg/dL and that BLL in children living in Western Georgia were higher than those in Eastern regions. In response to these findings, NCDC implemented written and verbal advice to the families of children who participated in the MICS-2018 on how to reduce Pb exposure. From August 2019 onwards, the state program of clinical follow-up was implemented. The design of this study was a longitudinal study. The intervention of interest was the public health advice and medical follow-up, and the outcome was defined as the difference in BLL between the MICS-2018 survey and the state program follow-up. We observed a significant overall reduction in median BLL between MICS-2018 and state program follow-up in both August 2019 and the latest results (until December 2019). However, we did not observe any significant further reduction between August and the most recent BLL results. In the Georgian setting, written and verbal communication targeting individual households, alongside home visits to the most exposed, effectively reduced BLL in children.

Substance abuse has been considered as a growing challenge in Georgia that is closely linked with human immune deficiency virus (HIV) and hepatitis C transmission due to unsafe injection and other uncontrolled behaviors. Methadone maintenance therapy is one of the major treatment options for opioid-dependent individuals. It has proven efficacy in decreasing illegal opioid consumption and criminal behavior as well as reducing the level of HIV infection, mortality, HCV infection, and increasing social functioning. The data was initially extracted from the electronic database, as of October 30, 2015, for the patients undergoing methadone maintenance therapy in 2014 and 2015. We used two types of statistical analysis: binary regression and time-to-event analysis (Kaplan-Meier). For binary regression analysis, patients who initiated the treatment 12, 9, 6, and 3 months prior to October 30, 2015, respectively, were eligible for >12-, >9-, >6-, and >3-month retention analysis. We identified two types of the retention periods: (I) “the program specific retention period” (the time spent (uninterruptedly) in the Global Fund to Fight HIV/AIDS, Tuberculosis, and Malaria (GFATM) opioid substitution treatment (OST) program after the clients’ last entry) and (II) “being on OST retention period” (the time spent (uninterruptedly) on OST since the clients’ last entry). For time-to-event analysis, the two different endpoints were investigated: (i) dropouts and (ii) being detained. The analysis showed that at each time point, “being on OST retention” rates are slightly higher than “program specific retention” rates. The percentages of patients retained in OST treatment after 3, 6, 9, and 12 months from the initiation of the treatment, respectively, were 89, 86, 85, and 83% and the percentages of patients retained in the GFATM program at the same time points were 88, 83, 82, and 80%. Patients older than 40 years are twice as likely to stay in the program compared to younger individuals. Gender is only associated with >9 and >12 months retention with approximately three times the odds for men compared to women. The strength of the association between hepatitis C status and “program specific” retention increases with time spent in the program as p values decrease from 0.07 for >3- and >6-month retention to 0.01 for >9- and >12-month retention. The younger age group was more likely to get dropouts and be detained. HIV status and social status did not show statistically significant association with retention. These findings identify the need for more support for younger patients as they are more vulnerable to dropouts and detention compared to the older age group, especially during the early stage of treatment.

In the Republic of Georgia, a 2018 national survey estimated that more than 40% of children aged 2–7 years had a blood lead concentration (BLC) of more than 5 µg/dL. The objective of this study was to document the feasibility of employing lead isotope ratios (LIRs) to identify and rank the Pb (lead) exposure sources most relevant to children across Georgia. A cross-sectional survey between November 2019 and February 2020 of 36 children previously identified as having BLCs > 5 µg/dL from seven regions of Georgia involved the collection of blood and 528 environmental samples, a questionnaire on behaviours and potential exposures. The LIRs in blood and environmental samples were analysed in individual children and across the whole group to ascertain clustering. A fitted statistical mixed-effect model to LIR data first found that the blood samples clustered with spices, tea, and paint, then, further isotopically distinct from blood were sand, dust, and soil, and lastly, milk, toys, pens, flour, and water. Analysis of the LIRs provided an indication and ranking of the importance of Pb environmental sources as explanatory factors of BLCs across the group of children. The findings support the deployment of interventions aimed at managing the priority sources of exposure in this population.

Introduction: The major challenge in the HIV epidemic in Georgia is a high proportion of undiagnosed people living with HIV (estimated 48%) as well as a very high proportion of late presentations for care, with 66% presenting for HIV care with CD4 count <350 and 40% with 36). In addition, CD4 count at diagnosis (cells/mm3) (≤350 or >350) together with all above factors were tested for the association with attrition through Poisson regression. Results: Overall, 317 patients retained in care, representing 65% of those diagnosed (n = 488). Out of eligible 295 patients, 89.5% were on treatment and 84% of those viral load count was measured after 6 months of antiretroviral treatment initiation had HIV-1 viral load <1000 copies/mL. Patients reporting injecting drug use as a route-of HIV transmission had two times the odds (95% confidence interval = 1.34–3.49) to be diagnosed late and patients reporting male-to-male contact as a way of HIV transmission had half the odds (odds ratio = 0.46 (95% confidence interval = 0.26–0.81)) of late diagnosis compared to patients acquiring HIV through heterosexual contact. Patients older than 36 years were more likely to being diagnosed late. Conclusion: More attention should be given to injecting drug users as they represent the most at-risk population for late diagnosis together with older age and attrition.
