RESUMO

This study aimed to analyse the seroprevalence of SARS-CoV-2 in Kazakhstan. This is a cross-sectional study of adult population in Kazakhstan for the period from October 2021 to May 2022. For the study, 6 720 people aged 18 to 69 were recruited (from 17 regions). The demographic data were collected and analysed. Gender was evenly distributed (males 49.9%, females 50.1%). Women exhibited a higher seroprevalence than men (IgM 20.7% vs 17.9% and IgG 46.1% vs 41.5%). The highest prevalence of IgM was found in the age group of 30-39. However, the highest prevalence of IgG was detected in the age group of 60-69. The seroprevalence of IgG increased across all groups (from 39.7% in 18-29 age groups to 53.1% in 60-69 age groups). The odds for a positive test were significantly increased in older age groups 50-59 (p < 0.0001) and 60-69 (p < 0.0001). The odds of a positive test were 1.12 times higher in females compared to males (p = 0.0294). The odds for a positive test were significantly higher in eight regions (Astana, Akmola, Atyrau, Western Kazakhstan region, Kostanai, Turkestan, Eastern Kazakhstan region, and Shymkent) compared to Almaty city. The odds of a positive test were three times higher in Astana and the Western Kazakhstan region than in Almaty city. In urban areas, the odds of a positive test were 0.75 times lower than in rural areas (p < 0.0001). The study's results showed an adequate level of seroprevalence (63%) that exceeds the essential minimum of herd immunity indicators in the country. There was significant geographic variability with a higher prevalence of IgG/IgM antibodies to SARS-CoV-2 in rural areas.

RESUMO

BACKGROUND: Ambulatory based treatment of tuberculosis has been recently introduced in Kazakhstan. We sought to assess the attitudes of the general population, TB patients and their household members towards ambulatory TB treatment and identify how knowledge of TB is associated with these attitudes. METHODS: New pulmonary TB cases and their household and community controls were recruited from three regions of Kazakhstan in 2012-2014. 1083 participants completed audio computer-assisted self interviews to assess their knowledge of TB and attitudes towards ambulatory care. Mixed effects logistic regression models were used to identify factors associated with attitudes toward ambulatory TB treatment. RESULTS: The proportion of people who considered ambulatory TB treatment as appropriate was very low (24.9%). Positive attitudes towards ambulatory TB treatment were significantly associated with region of residence, higher level of education, family support and experience with TB. The association between sufficient tuberculosis knowledge and favorable attitude toward ambulatory treatment was stronger among community controls compared to TB patients and their family members. CONCLUSIONS: This study provides insight into attitudes toward ambulatory TB treatment among different groups and the specific influence of TB knowledge on these attitudes. Our findings can inform the process of integration of new TB treatment strategies and the development of appropriate education and advocacy programs in the general population.

RESUMO

This study compares sexual risk behaviors among male and female migrant market vendors in Almaty, Kazakhstan. From the Barakholka Market, 209 male and 213 female market vendors were randomly recruited. Self-reported data were collected through standardized face-to-face interviews. Dry blood spot was used as specimen for syphilis testing. Propensity score stratification was used to estimate adjusted prevalence or rate ratios by gender. Compared to male migrant workers, females had lower HIV knowledge and were less likely to have multiple sexual partners. There was no evidence of a gender difference for prevalence of syphilis, condom use with unsteady partners, and safe sex communication between couples. Associations between mobility patterns and engagement in multiple sexual partnerships were stronger among women than men. Efforts should be made to mitigate the gender differential in HIV knowledge among migrants, especially women. Such efforts need to be implemented in both home and host countries.

RESUMO

This paper examines prevalence rates of HIV, HCV, and syphilis among a sample of injecting drug users (IDUs) and their heterosexual intimate partners (N = 728) from Almaty, Kazakhstan. The study uses baseline data from Project Renaissance, a couple-based HIV prevention intervention delivered to a couple where one or both partners are IDUs. HIV prevalence rates among female and male IDUs were 28 %. Among the full sample, 75 % had HCV, and 13 % tested positive for the syphilis antibody test. Only 10 % of the sample ever visited a needle exchange program. One-fourth (25.3 %) had never been tested for HIV. One-quarter of those who tested positive were unaware of their status. Being HIV positive was associated with a history of incarceration, being an IDU, and having access to needle exchange programs. The findings call for increasing efforts to improve access to HIV testing, prevention, treatment, and care for IDUs in Almaty, Kazakhstan.

RESUMO

BACKGROUND: Vaccination rates worldwide have declined in recent years. This decrease is primarily driven by vaccine hesitancy, which remains understudied in Central Asia, including Kazakhstan. Furthermore, there is great concern about parental hesitancy toward COVID-19 vaccines, as previous studies have focused on adult vaccine hesitancy. The current study was conducted by UNICEF and funded by USAID to explore the drivers of routine and COVID-19 immunization behaviors among parents and caregivers in Kazakhstan. METHODS: Using a cross-sectional methodology, researchers conducted 3081 face-to-face interviews with parents and caregivers of children aged 0-17 years across cities and villages in Kazakhstan. A tablet-based questionnaire (CAPI) was utilized, collecting participants' data on sociodemographic characteristics, childhood and COVID-19 vaccination behaviors, and potential drivers. RESULTS: Total of 239 participants (7.8%) were found to previously refuse vaccination due to their own beliefs. Stronger belief that vaccines are efficacious (AdjOR = 0.47), stronger belief that childhood vaccines are safe and danger of vaccine-preventable diseases is high (AdjOR = 0.73), firmer trust in societal factors (AdjOR = 0.77) and positive attitudes of family members toward immunization (AdjOR = 0.6) were significantly associated with parental refusal of childhood vaccines. The large proportion of respondents (N = 2,634, 85.6%) missed the COVID-19 vaccination of their child or were unwilling to get vaccinated. Stronger belief that COVID-19 vaccines are safe and efficacious (AdjsOR = 0.18), lacking important information about COVID-19 vaccines (AdjOR = 1.25) and parents being unvaccinated against COVID-19 (AdjOR = 2.3) were significant predictors of vaccine hesitancy. CONCLUSION: This study revealed numerous socio-demographic and behavioral factors significantly associated with parental refusal of childhood vaccines and hesitancy toward COVID-19 vaccines. Many parents not refusing vaccination possessed negative attitudes towards vaccines. Potential changes in their attitudes and beliefs of parents were observed compared to findings from pre-COVID era. Continuous monitoring of parental hesitancy, proper interventions and education of healthcare workers are suggested to reduce parental vaccine hesitancy.

RESUMO

The study aimed to identify the possible causes of COVID-19 outbreak and its development in a general hospital in Almaty (from April 11 to May 6, 2020), where 682 persons were identified with a COVID-19. 546 were hospital employees (48.9%), including doctors (57.8%), nurses (53.4%), junior medical personnel (54.4%) and other personnel (23.3%), and also among 136 patients. The attack rate among women was 50.0%, and incidence rate was higher amongst young employees < 30 years old (57.0%). The analysis showed that there was a failure of the management of the medical personnel in such critical situation.

RESUMO

The COVID-19 pandemic had significant impacts on mental health. We examined factors associated with symptoms of depression and anxiety during the COVID-19 pandemic in Kazakhstan. We surveyed 991 adults in Kazakhstan in July 2021 using multistage stratified sampling. Depression and anxiety were measured with the Patient Health Questionnaire-4. We conducted logistic regression to assess associations between depression and anxiety and sociobehavioral factors. Overall, 12.01% reported depressive symptoms and 8.38% anxiety. Higher likelihood of depression was associated with being female (AOR: 1.64; 95% CI [1.05, 2.55]), having experience with COVID-19 in the social environment (AOR: 1.85; 95% CI [1.1-3.14]), experiencing food insecurity (AOR: 1.80; 95% CI [1.11-2.89]), increased family conflict (AOR: 2.43; 95% CI [1.32-4.48]) and impaired healthcare access (AOR: 2.41; 95% CI [1.32-4.41]). Higher likelihood of anxiety was associated with being female (AOR: 3.43; 95% CI [1.91-6.15]), increased family conflict (AOR: 2.22; 95% CI [1.11-4.44]) and impaired healthcare access (AOR: 2.63; 95% CI [1.36-5.12]). Multiple factors were associated with mental health in Kazakhstan during the COVID-19 pandemic. Further research is needed to determine the extent to which these factors and their associated mental health outcomes may persist.

RESUMO

Background and Aims: Seroprevalence studies are needed to determine the cumulative prevalence of SARS-CoV-2 infection and to develop pandemic mitigation strategies. Despite the constant monitoring and surveillance, the true level of infection in the population of Kazakhstan remains unknown. The aim of this study was to determine the sero-prevalence of SARS-CoV-2 in the main cities of Kazakhstan. Methods: The research was conducted as a cluster-randomized cross-sectional national household study in three cities of Kazakhstan. The study covered the period: from October 24, 2020, to January 11, 2021. A total of 5739 people took part in the study. All participants agreed to be tested for antibodies to IgM/IgG. Demographic characteristics were analyzed. The presence of symptoms of respiratory diseases and the results of polymerase chain reaction (PCR) testing were determined. The antibodies to the SARS-CoV-2 virus were detected using the method of enzyme-linked immunosorbent assay (ELISA). Results: There was significant geographic variability with a higher prevalence of IgG/IgM antibodies to SARS-CoV-2 in Almaty 57.0%, in Oskemen 60.7% than in Kostanay 39.4%. There were no significant differences in prevalence between men and women (p ≥ 0.05). In Almaty, only 19% of participants with antibodies reported the presence of respiratory symptoms during a pandemic. At the same time, the percentage of patients with antibodies who had respiratory symptoms was 36% in Oskemen and 27% in Kostanay. Conclusion: The findings indicate that despite reasonable level of seroprevalence, the country has not yet reached the baseline minimum of herd immunity scores. The prevalence estimates for asymptomatic or subclinical forms of the disease ranged from 64% to 81%. Thus, given that almost half of the population of Kazakhstan remains vulnerable, the importance of preventive strategies such as social distancing, the use of medical masks, and vaccination to protect the population from the transmission of SARS-CoV-2 is highly critical.

RESUMO

OBJECTIVES: We examined the relationships between mobility characteristics and sexual risk behaviors among male and female migrant market vendors in Almaty, Kazakhstan. METHODS: Participants completed a structured interview covering sociodemographics, mobility characteristics, sexual behaviors, and biomarkers for HIV, HCV, and syphilis. We used multivariate analyses to examine associations between mobility patterns and HIV risks after adjusting for sociodemographics. RESULTS: Longer duration of a participant's last trip outside Almaty increased the odds of reporting multiple sexual partners. More frequent travel to visit family or friends was associated with multiple sexual partners and unprotected sex with steady partners. More frequent travel to buy goods in the past year was associated with multiple sexual partners. Men who traveled more often to buy goods were more likely to have purchased sex within the previous 90 days. CONCLUSIONS: Relationships between mobility patterns and sexual risk behaviors underscore the need for HIV-prevention strategies targeting the specific transmission dynamics that migrant vendors are likely to present.

RESUMO

Background: To date, there have been no studies of COVID-19 infection in children in Central Asia, particularly the Republic of Kazakhstan. This report analyses the epidemiological data on COVID-19 infection in children in Kazakhstan.Methods: The study included 650 paediatric patients diagnosed with COVID-19. Demographic and epidemiological data and the symptoms and radiological evidence of complications were collected and analysed. Children were sub-divided into four groups: neonates/infants, young children, older children and adolescents.Results: All of the 650 children were under 19 years of age, 56.3% of whom were male, and 122 (18.8%) were newborns and infants. The majority of cases (n = 558, 85.8%) were asymptomatic and only four cases were severe (0.6%). The symptoms were as follows in descending order: cough (14.8%), sore throat (12.8%), fever (9.1%) and rhinorrhoea (5.5%). Diarrhoea (2%), dyspnoea (1.8%) and muscle pain were rare (1.1%). Only three children required intensive care, including invasive ventilation. One patient had acute respiratory distress syndrome. There were no deaths.Conclusion: Most cases of COVID-19 infection in children in Kazakhstan were asymptomatic or the symptoms were mild. Only three patients required intensive care.

RESUMO

BACKGROUND: This study aimed to analyze the demographic and epidemiological features of identified COVID-19 cases in Kazakhstan. STUDY DESIGN: A cross-sectional study. METHODS: This cross-sectional study aimed to analyze COVID-19 cases (n=5116) collected from March 13 to June 6, 2020, in Kazakhstan. The data were obtained from a state official medical electronic database. The study investigated the geographic and demographic data of patients as well as the association of COVID-19 cases with gender and age. The prevalence of symptoms, the presence of comorbidities, complications, and COVID-19 mortality were determined for all patients. RESULTS: The mean±SD age of the patients in this study was 34.8±17.6 years, and the majority (55.7%) of COVID-19 cases were male and residents of cities (79.6%). In total, 80% of the cases had the asymptomatic/mild form of the disease. Cough (20.8 %) and sore throat (17.1%) were the most common symptoms among patients, and pneumonia was diagnosed in 1 out of 5 cases. Acute respiratory distress syndrome (ARDS) was recorded in 1.2% of the patients. The fatality rate was 1% in the study population and lethality was 2.6 times higher in males compared to females.  Each additional year in age increased the probability of COVID-19 infection by 1.06 times. The presence of cardiovascular, diabetes, respiratory, and kidney diseases affected the rate of mortality (P<0.05). CONCLUSION: The results demonstrated a high proportion (40%) of the asymptomatic type of coronavirus infection in the Kazakhstan population. The severity of COVID-19 symptoms and lethality were directly related to the age of patients and the presence of comorbidities.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a global public health problem, and continuous monitoring is essential for both its management as well as the management of other chronic diseases. Telemonitoring using mobile health (mHealth) devices has the potential to promote self-management, improve control, increase quality of life, and prevent hospital admissions. OBJECTIVE: This study aims to demonstrate whether a large-scale study assessing the use of mHealth devices to improve the treatment, assessment, compliance, and outcomes of chronic diseases, particularly COPD and cardio-metabolic syndrome, is feasible. This will allow our team to select the appropriate design and characteristics for our large-scale study. METHODS: A total of 3 cohorts, with 9 participants in each, will use mHealth devices for 90 days while undergoing the current standard of care. These groups are: 9 "non-COPD," otherwise healthy, smokers; 9 "grey zone" smokers (forced expiratory volume in 1 second/ forced vital capacity ≥0.70 after bronchodilator treatment; COPD Assessment Test ≥10); and 9 smokers diagnosed with Stage 1-3 COPD. Rates of recruitment, retention, and adherence will be measured. Overall, two mHealth devices will be utilized in the study: the AnaMed Original Equipment Manufacturer device (measures distance, energy expenditure, heart rate, and heart rate variability) and the Air Next mobile spirometry device. The mHealth devices will be compared against industry standards. Additionally, a questionnaire will be administered to assess the participants' perceptions of the mHealth technologies used. RESULTS: The inclusion of participants started in June 2019. Study results will be published in peer-reviewed scientific journals. CONCLUSIONS: This study will demonstrate whether a large-scale study to assess the use of mHealth devices to improve the treatment, assessment, compliance, and outcomes of chronic diseases, particularly COPD and cardio-metabolic syndrome, is feasible. It will also allow the research team to select the appropriate design and characteristics for the large-scale study.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a global public health problem. It is the third-leading cause of death in the world, the fourth leading cause of death in Kazakhstan, and is strongly associated with smoking. Smoking cessation reduces the severity of respiratory symptoms and COPD exacerbations. Heated tobacco products, such as HeatSticks heated by the iQOS device, a smoke-free electronic device, may serve as less risky alternatives to conventional combustible cigarettes. OBJECTIVE: The purpose of this study is to evaluate frequency of exacerbations, respiratory symptoms, physical exercise intolerance, and abnormal lung functions, as well as other parameters and comorbidities among men and women aged 40-59 residing in Almaty, Kazakhstan, who use iQOS with HeatSticks compared to smokers of conventional cigarettes. METHODS: This is a 5-year single-center cohort observational study. It includes two cohorts of participants consisting of men and women aged 40-59 residing in the city of Almaty, Kazakhstan: (1) smokers of combustible cigarettes (control group) and (2) users of iQOS with HeatSticks (exposure group). The study has baseline and periodic (ie, annual) comprehensive clinical assessments, as well as continuous COPD case-finding activities and registration of acute respiratory exacerbations over the course of the 5-year observation period. Study measures include spirometry, chest computed tomography, electrocardiography, physical exams, laboratory testing of serum for biomarkers of inflammation and metabolic syndrome, anthropometry, and the 6-minute walk test. Information about COPD symptoms will be collected using the COPD Assessment Test. RESULTS: Participant recruitment began December 2017, and enrollment is expected to last until late summer 2018. CONCLUSIONS: This is the first cohort observational study in Kazakhstan to assess differences in lung function between users of the heated tobacco product, iQOS with HeatSticks, and smokers of conventional combustible cigarettes. The study results will add to knowledge on whether switching from combustible cigarettes to iQOS with HeatSticks affects respiratory symptoms and diseases, including the development and progression of COPD.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is significantly underdiagnosed in Kazakhstan, and there is no previously conducted study on COPD prevalence in the country. OBJECTIVE: The purpose of this study is to assess the prevalence of COPD among individuals aged 40 to 59 years based on results of spirometry before and after bronchodilator, presence of structural changes in the lungs (emphysema, inflammatory changes, and thickening of the walls of the large and small airways) detected by computer tomography, and the symptoms of COPD. The study has 3 study groups: smokers of conventional cigarettes, those who had quit smoking 1 to 5 years ago, and those who haven't smoked cigarettes. METHODS: This is an observational study with a cross-sectional design among individuals aged 40 to 59 years in Almaty, Kazakhstan. The sample of 900 individuals of both sexes contains 500 smokers, 200 ex-smokers, and 200 never-smokers. Study measures include spirometry, chest computed tomography, electrocardiography, physical exams, laboratory testing of serum, anthropometry, and 6-minute walk test. Data are collected by computer-assisted personal interviewing with tablets. The questionnaire was designed to explore possible COPD risk factors including history of smoking, current smoking, level of smoking exposure (in pack-years), passive smoking, occupational and environmental hazards, and covariates: age, gender, ethnicity, education, occupation, and self-reported morbidity. COPD Assessment Test (CAT) is used to collect information about COPD symptoms. RESULTS: We have completed the participant recruitment and study procedures. Currently, we are working on data processing and data analysis. The authors anticipate the preliminary results should be available by September 2017. Study results will be published in peer-reviewed scientific journals. CONCLUSIONS: This is the first study in Kazakhstan that assesses prevalence of COPD and its comorbidities in the adult population aged 40 to 59 years. The results of the study will be useful for improving COPD preventive measures, better COPD screening, identification, and registration. Findings of the study will also contribute to global knowledge on the epidemiology of COPD.

RESUMO

BACKGROUND: Sputum smear-positive tuberculosis (TB) patients have a high risk of transmission and are of great epidemiological and infection control significance. Little is known about the smear-positive populations in high TB burden regions, such as Kazakhstan. The objective of this study is to characterize the smear-positive population in Kazakhstan and identify associated modifiable risk factors. METHODS: Data on incident TB cases' (identified between April 2012 and March 2014) socio-demographic, risk behavior, and comorbidity characteristics were collected in four regions of Kazakhstan through structured survey and medical record review. We used multivariable logistic regression to determine factors associated with smear positivity. RESULTS: Of the total sample, 193 (34.3%) of the 562 study participants tested smear-positive. In the final adjusted multivariable logistic regression model, sex (adjusted odds ratio (aOR) = 2.0, 95% CI:1.3-3.1, p < 0.01), incarceration (aOR = 3.6, 95% CI:1.2-11.1, p = 0.03), alcohol dependence (aOR = 2.6, 95% CI:1.2-5.7, p = 0.02), diabetes (aOR = 5.0, 95% CI:2.4-10.7, p < 0.01), and physician access (aOR = 2.7, 95% CI:1.3-5.5p < 0.01) were associated with smear-positivity. CONCLUSIONS: Incarceration, alcohol dependence, diabetes, and physician access are associated with smear positivity among incident TB cases in Kazakhstan. To stem the TB epidemic, screening, treatment and prevention policies should address these factors.

RESUMO

BACKGROUND: This study examined the association between incident pulmonary tuberculosis (TB) and social and behavioral characteristics in Almaty Oblast, Kazakhstan from 2012 to 2013. METHODS: We used a matched case-control design to estimate the role of factors for acquiring pulmonary TB. Totally 324 individuals were recruited from Sep 2012 to Mar 2013. Participants included 110 TB index cases with newly detected pulmonary TB. Each case was matched with one household and one community control. A total of 107 household and 107 community controls were included to the study. Adjusted odds ratios measuring associations between TB and risk factors were calculated by using a conditional multiple logistic regression analysis. RESULTS: TB cases were more likely to be younger, recent smokers and have diabetes, when compared to household controls. Between TB cases and community controls, TB was significantly associated with age, non-married family status, living in a rented home, recent smoker, and having diabetes. Comparing TB cases with community controls, we found that foreign birth was marginally associated with incident TB case status. CONCLUSION: Our findings confirm the role of modifiable risk factors for TB in Kazakhstan; highlighting the importance of developing interventions addressing social determinants and proximate risk factors for high TB burden regions.

RESUMO

SETTING: Tuberculosis (TB) is highly prevalent in prisons of the former Soviet Union. OBJECTIVE: To understand the behavioral, demographic and biological factors placing inmates in Tajikistan at risk for active TB. DESIGN: We administered a behavioral and demographic survey to 1317 inmates in two prison facilities in Sughd province, Tajikistan along with radiographic screening for pulmonary TB. Suspected cases were confirmed bacteriologically. Inmates undergoing TB treatment were also surveyed. In-depth interviews were conducted with former prisoners to elicit relevant social and behavioral characteristics. RESULTS: We identified 59 cases of active pulmonary TB (prevalence 4.5%). Factors independently associated with increased prevalence of active TB were: HIV-infection by self-report (PR 7.88; 95%CI 3.40-18.28), history of previous TB (PR 10.21; 95%CI 6.27-16.63) and infrequent supplemental nutrition beyond scheduled meals (PR 3.00; 95%CI 1.67-5.62). Access to supplemental nutrition was associated with frequency of visits from friends and family and ability to rely on other inmates for help. CONCLUSION: In prison facilities of Tajikistan, HIV-infection, injection drug use and low access to supplemental nutrition were associated with prevalent cases of active pulmonary TB. Policies that reduce HIV transmission among injection drug users and improve the nutritional status of socially isolated inmates may alleviate the TB burden in Tajikistan's prisons.

RESUMO

BACKGROUND: Kazakhstan and other countries in Central Asia are experiencing a rapidly growing HIV epidemic, which has historically been driven by injection drug use, but is more recently being fueled by heterosexual transmission. METHODS: This paper examines HIV and HCV infection, as well as sexual and drug-related risks among female partners of men who inject drugs (MWID), comparing females who inject drugs (FWID) to non-injecting female partners on socio-demographic, relationship context, and structural characteristics. RESULTS: The prevalence rate of HIV was 30.1% among FWID and 10.4% among non-IDU female partners of MWID. The prevalence rate of HCV was 89.8% among FWID and 14.8% among female non-IDUs. Less than one-fifth of all female participants had access to HIV education and services or harm reduction programs. Although high rates of non-injection drug use and sexual risk behaviors were found among both FWID and non-injecting female partners of MWID, we found that FWID were more likely to be HIV seropositive (aRR=3.03; 95% CI=1.78, 5.18) and HCV seropositive than non-IDU females (aRR=6.05; 95% CI=4.05, 9.04), were more likely to have used alcohol or drugs before sex (aRR=1.67; 95% CI=1.40, 2.00), and were more likely to have used sedatives, barbiturates, tranquilizers, sleeping pills, or painkillers that were not prescribed by a physician (aRR=17.45; 95% CI=8.01, 38.01). CONCLUSION: Given the spread of the HIV epidemic to heterosexual partners in Kazakhstan, more attention is needed in research, prevention, and policies regarding female partners of male injection drug users.

RESUMO

OBJECTIVE: Project Renaissance is a randomized controlled trial of an HIV/hepatitis C virus (HCV)/sexually transmitted infection (STI) prevention intervention conducted in Almaty, Kazakhstan. We hypothesized that couples assigned to the intervention of interest will have lower incidence of HIV, HCV, STIs, rates of unprotected sex, and unsafe injection over the 12-month follow-up period compared with those assigned to an attention control arm. DESIGN: A total of 300 couples (600 participants) where one or both partners reported injecting drugs in the past 90 days were randomized to 1 of 2 arms: (1) a 5-session HIV/HCV/STI prevention intervention (risk reduction: RR) or (2) a 5-session Wellness Promotion (WP) intervention. RESULTS: Over the 12-month follow-up period, assignment to RR compared with WP significantly lowered the incidence of HCV infection by 69% [incidence rate ratios (IRR) = 0.31, 95% (CI) confidence interval: 0.10 to 0.90, P = 0.031]. Although differences were not statistically significant, RR participants had a lower incidence of HIV infection by 51% (IRR = 0.49, 95% CI: 0.16 to 1.48, P = 0.204) and any STI by 37% (IRR = 0.63, 95% CI: 0.21 to 1.93, P = 0.418) than WP participants. RR participants reported significantly fewer numbers of unprotected vaginal sex acts with their study partners (IRR = 0.58, 95% CI: 0.36 to 0.93, P = 0.024) and more consistent condom use (odds ratios = 2.30, 95% CI: 1.33 to 4.00, P = 0.003) over the entire follow-up period compared with WP participants. CONCLUSIONS: Project Renaissance demonstrated a significant effect for biological and behavioral endpoints. Findings draw attention to an HIV/HCV/STI prevention intervention strategy that can be scaled up for drug-involved couples in harm reduction programs, drug treatment, and criminal justice settings.

RESUMO

INTRODUCTION: As a population profoundly affected by the HIV epidemic and in critical need of linkages to HIV treatment and care, PWID in Central Asia remain largely underserved. This paper provides an overview of the current state of HIV testing and counseling in Central Asia for PWID, identifies main barriers leading to gaps in service delivery, and discusses implications for improving strategies that promote HIV testing for PWID. METHODS: We reviewed a number of sources for this paper including unpublished government reports, published papers, and Ministries of Health of Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan country progress reports to the UN General Assembly Special Session on HIV/AIDS (UNGASS) for 2012. RESULTS: Between 29 and 65% of PLWH in some Central Asian countries have been tested for HIV in the last 12 months. The rates have been increasing in the recent years but still are relatively low. Stigma, discrimination, human rights violations, and repressive legislation are barriers to HTC for people who inject drugs (PWID). CONCLUSION: The use of innovative evidence-based HTC models, such as community mobile-vans, self-testing at home, and rapid HIV testing among PWID in Central Asia are discussed and recommendations given regarding amendments in legislation and scaling up of existing community-based pilot projects to support HIV testing among PWID in CA.
