Linking intravenous drug users to treatment through non-governmental organizations in Ukraine: how well is it working?

INTRODUCTION: Alliance for Public Health, the International Charitable Foundation, coordinates HIV prevention in Non-Governmental Organizations (NGO) working with people who inject drugs (PWID) in Ukraine. We aimed to describe the performance of the differential model of linking PWID to HIV care and treatment (Community Initiated Treatment Intervention - CITI). METHODOLOGY: A retrospective cohort study using routine program data was conducted among 8,927 PWID who were tested positive for the first time during January 2016 - June 2017. Study outcomes were enrollment into CITI and initiating antiretroviral treatment (ART). Factors associated with outcomes were estimated by logistic regressions with random effects. RESULTS: Among the study participants, 54% enrolled into CITI and 23% initiated ART. CITI enrolment was associated with being married (adjusted odds ratio (AOR) = 1.17; 95%: 1.02-1.34); less than weekly compared to daily (AOR = 1.31; 95%: 1.13-1.52); less than 5 years of drug use compared to > 14 years (AOR = 1.73; 95%: 1.40-2.13), and having no criminal records (AOR = 1.30; 95%: 1.12-1.50). Factors of non-ART initiation were male gender (AOR = 1.33; 95%: 1.16-1.53); being single (AOR = 1.48; 95%: 1.21-1.82); drug use duration > 14 years compared to < 5 years (AOR = 1.38; 95%: 1.03-1.85), unemployment (AOR = 1.45; 95%: 1.15-1.83) and history of incarceration (AOR = 1.21; 95%: 1.003-1.45). CONCLUSION: Mobilizing the NGO community and PWID to engage in outreach HIV testing activity and harm reduction for key populations has succeeded in opening the gateway to prevention, care and ART for thousands of PWID in Ukraine.

Engaging people who inject drugs and their peers in HIV testing and harm reduction in Ukraine: do they make a difference?

INTRODUCTION: People Who Inject Drugs (PWID) should be offered HIV-testing and harm reduction services. We assessed the effectiveness of including PWID and their peers in HIV-testing by comparing for a period before (2013-2014) and after their introduction (2015-2017), the a) numbers HIV tested b) number enrolled in harm reduction and c) frequency of HIV-testing. METHODOLOGY: An analysis of programme data involved PWID aged ≥ 14 years (1st January 2013-31st December 2017) in Ukraine. Between 2013-2014, HIV-testing (VCT) was done by trained health workers. From 2015, this was Directly Assisted HIV Self-testing (DAST) done by social workers and peers. Optimized HIV case finding (OCF) was introduced (in 2016) as an overlapping strategy with DAST. RESULTS: A total of 844,837 HIV tests were done with 23,427 (2.8%) HIV-positive results. With VCT, there were 164,417 HIV tests compared to 639,685 after engagement of PWID and their peers (>3-fold increase). The highest HIV positive yield (20%) was when OCF was included. With increasing HIV-testing caseload, a progressive decrease in enrollment in harm reduction was seen (85% in 2014 to 47% in 2017, X2 for trend P < 0.001). OCF resulted in enrollment into harm reduction of 2722 HIV-positives, which was 35% higher than through DAST alone (7,5%). HIV re-testing almost doubled with DAST. CONCLUSION: Active engagement of PWID and their peers in HIV-testing increased uptake of HIV-testing. Including OCF has a synergistic effect in HIV-positive yield. Strategies are urgently needed to ensure that individuals who are HIV tested are enrolled in harm reduction.

Lymphotropic administration of photosensitizer as a model of target therapy of testicle inflammation: Experimental and clinical data.

BACKGROUND: The existence of zones of humoral skin-subskin tissue linkage with internal organs as well as the possibility of targeted administration of preparation into the affected organs were studied. METHODS: An experimental study of preparation and distribution in the bodies of mice was held by both intravenous and lymphotropic methods of administration. By means of detection with a photosensitizer (as a marker), the study was conducted on healthy mice and mice with testicle inflammation. Based on the experimental results, the study has been implemented into the clinical practice of treatment of acute inflammatory diseases of testicle and its epididymis. Patients were administered antibiotics either by the lymphotropic method, or by traditional methods. RESULTS: The concentration of the preparation, administered by the lymphotropic method, maintained in target organs (testicles) at a high level for a longer time, while the intravenous injections provided fast achievement of high concentrations. Moreover there was a lower level of accumulation of the photosensitizer in parenchymal organs after subcutaneous (lymphotropic) administration. CONCLUSIONS: The presence of humoral connection of certain areas of skin and subcutaneous tissue with testicles and their epididymis was proved. It was found that the lymphotropic administration leads to earlier clinical improvement and normalization of laboratory indices, and, thus, to significant reduction in hospital stay. Such results open the possibility of targeted drug delivery to the diseased organs. In perspective, the method may be used in treating patients not only in urology, but also in surgery, as well as for many acute, chronic or cancer diseases.

Ex vivo investigations on the potential of optical coherence tomography (OCT) as a diagnostic tool for reproductive medicine in a bovine model.

Routine infertility investigations in the male and female include imaging techniques such as ultrasonography and endoscopy (fertiloscopy). However, these techniques lack the resolution to localize vital sperm or to reveal detailed morphological analysis of the oviduct which is often the cause of infertility in females. Therefore we set out to evaluate the efficiency of optical coherence tomography (OCT) as a diagnostic imaging tool for micron-scale visualization of the male and female genital tract. Using the bovine as a model, the optical features of the Telesto(TM) , Ganymede(TM) (both Thorlabs) and Niris(TM) (Imalux) OCT imaging systems were compared.

Coryneform bacteria in human semen: inter-assay variability in species composition detection and biofilm production ability.

BACKGROUND: Coryneform bacteria constitute an important segment of male urogenital microbiota. They have been generally considered as saprophytes, although some species have been associated with prostatitis as well. At the same time, biofilm infections have been suspected as a cause of prostatitis. OBJECTIVE: To identify a set of coryneform bacteria isolated from semen of either healthy men or prostatitis patients applying different methods to reveal inter-assay variability and to determine their ability of adhesion and biofilm production. DESIGN: Coryneform bacteria were identified by API Coryne 2.0 biochemical identification system and 16S rDNA sequencing using different primer sets. Quantitative assessment of biofilm production was performed using crystal violet binding assay method. RESULTS: The most common species were Corynebacterium seminale, C. minutissimum, and Dermabacter hominis. Altogether 14 species and related genera were found. We observed the best inter-assay agreement when identifying C. seminale. Biofilm was observed in 7 out of 24 strains. The biofilm-producing strains belonged to Arthrobacter cumminsii, Dermabacter hominis, C. minutissimum, and Actinomyces neuii. No differences were found between the strains originating from prostatitis patients and healthy men. Dermabacter hominis strains were more potent biofilm producers than C. seminale strains (p=0.048). CONCLUSIONS: We can conclude that a wide variety of coryneform bacteria can be found from the male genital tract, although their exact identification is problematic due to insufficient representation in databases. Nearly one third of the strains are able to form biofilm that may give them an advantage for surviving several host- and treatment-related conditions.
