Epidemiologic and clinical characteristics of HIV/AIDS patients in Turkey, where the prevalence is the lowest in the region

Epidemiological trends and seasonal dynamics of tuberculosis in Southeastern Turkey

Background

Tuberculosis (TB) is an important public health issue. Determining TB trend and seasonal variability provides useful information for designing treatment strategies and control programs.

Aim

The present study attempts to investigate the epidemiological trend and the seasonal variations.

Materials and Methods

TB data containing 2450 cases were collected over a period of seven years in the province of Diyarbakir in southeast Turkey. Trend function and seasonal variability were investigated by statistical curve fitting, surface fitting, and autoregressive time series analysis.

Results

The study revealed a gradually decreasing trend in the number of TB cases over a period of seven years. Total TB incidence had seasonal variations (P = 0.04); there was a greater number of TB cases between April and July, with a peak in June. There were significant monthly seasonal variations with June peaks among females (P < 0.001), in patients in the age groups of 0-15 (P < 0.001) and 36-45 years (P < 0.001), in new cases (P < 0.001) and in the patients with pulmonary TB (P = 0.01). The extra-pulmonary TB cases peak in May (P = 0.01). Pulmonary TB and TB patients in the 36-45 age group had summer peak, while the other groups peaked at spring.

Conclusions

Spring and summer peaks detected in total TB cases and in many subgroups indicate that multicenter and comprehensive clinical studies are needed to explain these variations.

Opportunistic Infections Among Human Immunodeficiency Virus (HIV) Infected Patients in Turkey: A Systematic Review

This study aimed to identify opportunistic infections among human immunodeficiency virus (HIV) infected patients in Turkey. Therefore, we conducted a systematic literature review of the studies published up to October 1, 2022, in the Pubmed, Web of Science (WoS), and ULAKBİM TR Dizin databases. We searched for medical subject headings (MeSH) terms of (HIV) OR (AIDS) OR (human immunodeficiency virus) AND (opportunistic infections) AND (Turkey). Fifty-five studies in Pubmed, 68 in WoS, and 212 in ULAKBİM TR Dizin were listed with these keywords. After removing duplicated studies, we included 22 original articles, two poster presentations, one short communication, one letter to the editor, and 17 case reports/series. Out of 1582 patients, we defined 788 patients (49.8%) as late presenters. In addition, we detected tuberculosis (286, 5.5%), candidal infections (207, 4%), and Pneumocystis jirovecii pneumonia (PCP) (113, 2.1%) as the most frequent opportunistic infections. According to our analysis, late presentation is a major problem in our country, and more screening and sensitization campaigns should be carried out to ensure early diagnosis and earlier care of patients.

The Correlation of CD4+ T-Lymphocyte Count and Chemokine Ligand 13 Levels in Human Immunodeficiency Virus Patients Receiving Anti-retrovirus Therapy in Sanglah Central General Hospital

BACKGROUND: Human immunodeficiency virus (HIV) infection is an infectious disease caused by the HIV-1 or HIV-2 virus. Cluster of differentiation 4+ (CD4+) T lymphocytes have an important role in the immune process. Chemokine Ligand 13 (CXCL13) is chemotactic for receptor-expressing cells (CXCR5), including B cells and follicular helper (Tfh) T cells. CXCL13 examination can be used to detect HIV antibodies and as a marker of disease progression and monitoring anti-retrovirus therapy (ART) in HIV-infected patients. Giving ART will reduce CXCL13 levels and show B cell activation, so CXCL13 can be used as a new marker of immune or antibody formation during acute or chronic HIV infection. CXCL13 examination can be used to detect HIV antibodies and as a marker of disease progression and monitoring ART in HIV-infected patients. Giving ART will reduce CXCL13 levels and show B cell activation, so CXCL13 can be used as a new marker of immune or antibody formation during acute or chronic HIV infection. AIM: The aim of the study was to propose a study on the relationship between CD4+ T lymphocyte levels and CXCL13 levels in HIV patients who had received ART at the Sanglah Central General Hospital (RSUP), Denpasar. This study was start from March 2021 to August 2021 at the Sanglah Central General Hospital. MATERIALS AND METHODS: This study used analytic observational study with a cross-sectional design, conducted at the Voluntary Counseling and Testing and the Clinical Pathology Laboratory at Sanglah Central General Hospital with 55 samples include in inclusion criteria. RESULTS: In this study, the mean age of the research subjects was 42.18 ± 10.31 years with 58.2% male, 41.8% female having received ART with a mean of 63 months. The average number of CD4+ T lymphocytes was 451.53 ± 295.118. Median CXCL13 level was 50,551. The correlation between CXCL13 levels and the number of CD4+ T lymphocytes was −0.209. This correlation was not significant with p = 0.127 (p < 0.05), then partial correlation was performed. The partial correlation of CXCL13 levels and the number of CD4+ T lymphocytes was −0.308, a negative direction indicating there was an inverse correlation. This correlation is a significant with p = 0.023 (p < 0.05) after partial correlation and is in the category of weak correlation. CONCLUSIONS: There are a significant negative correlation after partial correlation of CXCL13 levels and the number of CD4+ T lymphocytes in HIV patients at Sanglah Hospital during the treatment phase.

Global prevalence and associated risk factors of diarrheagenic Giardia duodenalis in HIV/AIDS patients: A systematic review and meta-analysis

Giardia duodenalis is one of the leading causes of diarrhea, mostly in underdeveloped nations of Africa and Asia. The present review provides insights into the prevalence, odds ratios (ORs) and associated risk factors of giardiasis in HIV/AIDS patients. Four major English databases (Web of Science, PubMed, Scopus, and Google Scholar) were excavated for relevant literature without time limitation until 20 November 2020. Next, meta-analysis was performed using a random-effects model and 95% confidence intervals (CIs). As well, heterogeneity among studies was evaluated using Cochran's Q and the I²-statistic. Totally, 19,218 HIV/AIDS patients in 130 studies were examined, showing a 5% (95% CI: 4.2%-6%) pooled prevalence. Also, the weighted random-effects OR of G. duodenalis infection among HIV/AIDS patients in comparison with their controls in 48 case-control studies was estimated as 1.71% (95% CI: 1.1%-2.66%, p = 0.016). Based on sensitivity analysis, there was no remarkable variation in the pooled OR upon omitting individual studies. Diarrhea was a potent risk factor, since HIV/AIDS patients with diarrhea were 3.8-times (95% CI: 1.6-8.9, p = 0.002) more prone to G. duodenalis infection than those without diarrhea. Moreover, the prevalence of the parasitic infection was 1.2-times higher in patients without antiretroviral therapy (ART) than those with ART (p = 0.312). Meta-regression was employed to evaluate the possible association between G. duodenalis frequency in HIV/AIDS patients and some variables such as sample size, publication year, and HDI. Additionally, the pooled prevalence of G. duodenalis infection was estimated based on several subgroups, including publication years, WHO regions, countries, continents, country incomes, and CD4⁺ T-cell levels. Altogether, the epidemiology of giardiasis in HIV/AIDS patients and its association with various risk factors is still open to question and requires more detailed and comprehensive investigations.

Temporal Trends in the Epidemiology of HIV in Turkey

OBJECTIVE

The aim of this study was to analyze the temporal trends of HIV epidemiology in Turkey from 2011 to 2016.

METHODS

Thirty-four teams from 28 centers at 17 different cities participated in this retrospective study. Participating centers were asked to complete a structured form containing questions about epidemiologic, demographic and clinical characteristics of patients presented with new HIV diagnosis between 2011 and 2016. Demographic data from all centers (complete or partial) were included in the analyses. For the cascade of care analysis, 15 centers that provided full data from 2011 to 2016 were included. Overall and annual distributions of the data were calculated as percentages and the Chi square test was used to determine temporal changes.

RESULTS

A total of 2,953 patients between 2011 and 2016 were included. Overall male to female ratio was 5:1 with a significant increase in the number of male cases from 2011 to 2016 (p<0.001). The highest prevalence was among those aged 25-34 years followed by the 35-44 age bracket. The most common reason for HIV testing was illness (35%). While the frequency of sex among men who have sex with men increased from 16% to 30.6% (p<0.001) over the study period, heterosexual intercourse (53%) was found to be the most common transmission route. Overall, 29% of the cases presented with a CD4 count of >500 cells/mm3 while 46.7% presented with a CD4 T cell count of <350 cells/mm3. Among newly diagnosed cases, 79% were retained in care, and all such cases initiated ART with 73% achieving viral suppression after six months of antiretroviral therapy.

CONCLUSION

The epidemiologic profile of HIV infected individuals is changing rapidly in Turkey with an increasing trend in the number of newly diagnosed people disclosing themselves as MSM. New diagnoses were mostly at a young age. The late diagnosis was found to be a challenging issue. Despite the unavailability of data for the first 90, Turkey is close to the last two steps of 90-90-90 targets.

Clinico-Epidemiological Analysis of HIV/AIDS Patients

OBJECTIVE

The aim of this study was to examine clinico-epidemiological properties of HIV/AIDS patients.

MATERIALS AND METHODS

For this purpose, 115 HIV/AIDS patients monitored in our clinic between January 1, 1998, and December 31, 2013, were retrospectively evaluated.

RESULTS

For the 115 patients with a diagnosis of HIV/AIDS that we monitored, the mean age at the time of presentation was 34.5±13.21 (10-79) years. Eighty-nine (76.5%) patients were male and 27 (23.5%), female. In this study, HIV/AIDS was the most prevalent in the young male population with a low educational and sociocultural level. The most common mode of transmission in our patients was heterosexual relations: approximately 1 patient in 3 had a history of traveling to countries with a high prevalence of HIV/AIDS, namely, Russia and Ukraine. The examination of diagnosis with respect to years showed an increase in new cases since 2008. Only 21 (18.3%) of our patients were diagnosed through clinical symptoms, while 91 (81.7%) during routine scanning. At first presentation, 68% of our patients were stage A; 4.7%, stage B; and 27.3%, stage C. The mean length of the monitoring of our patients was 2.74 years (2-180 months). Thirteen (11.3%) patients died due to opportunistic infections and malignities. The most common opportunistic infection was tuberculosis (16.5%), followed by syphilis and HBV. Malignity, most commonly intracranial tumor, was seen in 8.6% patients.

CONCLUSION

The disease was generally seen in the young male population with a low sociocultural level, and it was most frequently transmitted by heterosexual sexual contact. This clearly shows the importance of sufficient, accurate information, and education on the subject of the disease and its prevention. The fact that many of our patients were diagnosed in the late stage due to stigma and that diagnosis was largely made through scanning tests confirms the importance of these tests in early diagnosis.

HIV prevalence among men who have sex with men in Istanbul

OBJECTIVES

The re-emergence of the HIV epidemic among men who have sex with men (MSM) represents a serious health issue. This study aimed to assess the HIV prevalence among MSM in a very low prevalence population of a large city.

METHODS

A public campaign to raise awareness of HIV infection and to provide access to anonymous testing was conducted in places frequented by MSM and through a mobile phone application. No identity information was requested from individuals contacting the call centre, and anonymous and free HIV testing was offered proactively. Those who agreed to have a test were provided a code number, which was used in blood sampling procedures.

RESULTS

Of 1200 subjects who contacted the call centre, 197 consented to undergo HIV testing and visited the laboratory to give a blood sample. Twenty-five subjects were found to have a reactive ELISA result on two different occasions plus a positive Western blot test result. Thus, the HIV prevalence in this group of MSM was 12.7%.

CONCLUSIONS

MSM remain a high risk group for HIV infection in a low prevalence setting, and thus represent a key target population for diagnostic and therapeutic interventions.

Changes in HIV demographic patterns in a low prevalence population: no evidence of a shift towards men who have sex with men

OBJECTIVES

This study aimed to examine the changes in HIV demographics over time in an exceptionally low prevalence population, with particular emphasis on men who have sex with men (MSM).

METHODS

A total of 1292 newly diagnosed HIV-positive patients registered in the ACTHIV-IST Study Group database between 2000 and 2014 were included. The changes occurring over time in the characteristics of patients at the time of initial admission were examined retrospectively.

RESULTS

A gradual increase in the total number of newly diagnosed patients was evident during the study period; however, it was not possible to show an increase in the proportion of MSM within the study population (p=0.63). There was a male predominance throughout the study (85% vs. 15%), with further increases in the proportion of males in recent years. The mean age was lower at the end of the study (p<0.05) and there was an increase in the number of unmarried patients (p<0.05).

CONCLUSIONS

Sexual preference patterns of HIV patients in extremely low prevalence populations may be different, possibly due to an early phase of the epidemic. Nevertheless, MSM still represent a target subgroup for interventions, since they account for a substantial proportion of cases and a resurgent epidemic may be expected among this group in later phases of the epidemic.

Scaling up combined community-based HIV prevention interventions targeting truck drivers in Morocco: effectiveness on HIV testing and counseling

Background

Truck drivers constitute an important bridging group in the HIV epidemic in Morocco. This study examined the effect of a community-based educational intervention in Morocco on HIV testing and counseling, in representative samples of truck drivers before (2007) and after (2012) the intervention.

Methods

Face-to-face structured interviews, adapted from UNAIDS documents, collected data on socio-demographic characteristics, HIV testing and counseling, and HIV risk behaviors in both the 2007 and 2012 surveys. Information about exposure to the intervention was also collected in the latter. Individuals exposed to the intervention were compared with those unexposed (i.e. unexposed in 2012, and all the 2007 pre-intervention sample).

Results

The 2012 group included 459 men with a median [IQR] age of 38 [31–44] years, 53% of whom reported exposure to the educational intervention. The percentage of participants tested for HIV and receiving HIV counseling in the last 12 months, was significantly higher in the 2012 group (29.6% vs 4.3% in 2007). Data from the 2012 survey confirmed a significant positive trend between being HIV tested and receiving counseling and the number of times a participant was exposed to the intervention (once: (OR = 5.17(2.38-11.25)), twice or more (OR = 19.16(10.33 - 35.53)). These results were confirmed after adjustment for employment, knowledge that the HIV test results would remain confidential, inconsistent condom use with occasional partners or sex workers, and when including individuals from 2007 considered unexposed.

Conclusions

Community-based educational interventions targeting truck drivers can be effective in increasing coverage of HIV testing and counseling, particularly if they are repeated and cover a considerable portion of this at-risk population. These results are encouraging for other countries which urgently need to implement prevention interventions for most-at-risk populations. Furthermore, they clearly show the power of community-based organization interventions in settings where resources for HIV prevention remain limited.

Need for multilevel strategies and enhanced acceptance of contraceptive use in order to combat the spread of HIV/AIDS in a Muslim society: a qualitative study of young adults in urban Karachi, Pakistan

This qualitative study explored knowledge, attitudes, beliefs and perceptions of sexual and reproductive health, focusing specifically on contraceptive use and HIV prevention among young unmarried men and women, 17-21 years, in urban Karachi, Pakistan. The main theme, identified as underlying meaning in the focus group discussions was “Societal norms and perceptions create barriers to knowledge and awareness about sexual and reproductive health matters among young adults”. A knowledge gap was revealed concerning HIV/AIDS and contraceptive use among young males and females, who have to rely on media and peers for information seeking. Study participants perceived that HIV/AIDS is incurable and carries a social stigma. It was further revealed, that there is an opposition towards contraceptive use from religious leaders. Young adults in Pakistan are in need of improved knowledge about HIV/AIDS and contraceptive use. Youth clinics and schools/colleges may play a significant role in this regard. The religious leaders need to be informed about the beneficial effects of contraceptives and they should be part of any family planning/contraceptive use program to ensure better community acceptance. At the structural level there is an urgent need for policies targeting the issue of sexual and reproductive health, particularly HIV/AIDS information and contraceptive use to target the young population. The health care services should be able to respond by offering relevant services.

HIV risk behaviors differ by workplace stability among Mexican female sex workers with truck driver clientele

Background

In a study of female sex workers (FSWs) servicing truck driver clients in Mexican border cities, we evaluated differences in HIV/STI risk behaviours determined by workplace.

Design and Methods

Our study was cross-sectional and its population comprised 100 FSWs from Nuevo Laredo (US border) and 100 FSWs from Ciudad Hidalgo (Guatemalan border). The main outcome was primary place of sex work defined as unstable (street, vehicle, gas station, etc.) vs stable (bar, brothel, and hotel). Logistic regression was used to identify correlates associated with trading sex at unstable workplaces in the last month.

Results

Of the FSWs surveyed, 18% reported an unstable workplace. The majority of FSWs surveyed were young (<30 years), single, had <9^th grade education, and had worked in the sex trade for a median of 4.9 years. After controlling for study site, FSWs with unstable vs stable workplaces were more likely to have a majority/all truck driver clientele, but were less likely to have visited a gynaecologist in the last year (OR 0.1, 95% CI 0.03-0.4) or ever had an HIV test (OR 0.1, 95% CI 0.06-0.3), and there was a trend towards lower condom use self-efficacy scores (OR 0.8 per unit increase, 95% CI 0.7-1.0). On multivariate regression, unstable workplace was associated with having majority/all truck driver clientele, being surveyed in Nuevo Laredo, and decreased odds of ever having an HIV test.

Conclusions

Among Mexican FSWs with truck driver clients, providing safe indoor spaces for sex work may help facilitate public health interventions that improve HIV/STI prevention and reproductive health outcomes.

Correlates of STI symptoms among female sex workers with truck driver clients in two Mexican border towns

Background

Female sex workers (FSW) are at increased risk for HIV and other STI due to occupation-related risks and exposures. Long-distance truck drivers have been implicated in the spread of HIV, but less is known about HIV/STI risks of FSW servicing truck drivers, especially in North America. As part of an international collaborative pilot study, we interviewed FSWs servicing truck driver clients along two major transportation corridors to explore factors associated with recent STI symptoms.

Methods

A cross-sectional study of 200 FSW was conducted in Mexico: 100 from Nuevo Laredo (U.S. border); 100 from Ciudad Hidalgo (Guatemalan border). Eligibility criteria included age ≥18 years, speaking English or Spanish, and having ≥1 truck driver client in the past month. The main outcome was reporting any recent STI symptoms, defined as experiencing genital/anal warts, genital ulcers/sores, genital itching, or abnormal vaginal discharge in the past 6 months. Logistic regression was used to identify correlates of recent STI symptoms.

Results

Median age of FSW was 29 years, 74% were single, 87% had <9^th grade education, and median income was 4000 pesos/month ($300 USD). Sex work occurred at a bar/cantina for 70%. One-quarter had never been tested for HIV, 53% reported lifetime drug use, 22% reported drinking alcohol before/during transactional sex and 17% reported recent STI symptoms. After controlling for age and study site, factors associated with STI symptoms were lifetime drug use (AOR 2.9, 95% CI 1.2-6.9), drug use before/during sex (AOR 2.8, 95% CI 1.1-7.1), alcohol use before/during sex (AOR 5.2, 95% CI 2.2, 12.6), forced sex ever (AOR 2.6, 95% CI 1.1-6.1), lifetime history of arrest (AOR 2.3, 95% CI 1.0-5.0), and being surveyed in Nuevo Laredo rather than Ciudad Hidalgo (AOR 4.8, 95% CI 2.0-10.0).

Conclusions

The associations we observed between recent STI symptoms and drug and alcohol use suggest that interventions are needed that promote consistent and effective safer sex practices, especially while under the influence of alcohol or other substances.

Profile of HIV/AIDS patients in a tertiary hospital in Istanbul, Turkey

BACKGROUND

In Turkey, the first HIV/AIDS case was reported in 1985. Although HIV/AIDS incidence has been increasing, only 3,671 cases have been documented to date in this country, with a population of 71,517,100. The aim of this study was to determine the epidemiologic and clinical features of patients with HIV infection and AIDS followed during a 3.5-year period.

METHODS

A total of 136 HIV-infected patients attending Infectious Diseases and Clinical Microbiology Outpatient Clinic of Haseki Training and Research Hospital between January 2006 and June 2009 were included in the study. Epidemiologic and clinical data, such as age, gender, marital status, occupation, level of education, transmission routes, condom usage, type of screening tests, clinical findings, and CD4 T-cell counts and viral loads at diagnosis, were collected retrospectively from case records completed on admission.

RESULTS

Patients with a diagnosis of HIV infection comprised a group of 136 persons (80% men, mean age 36 years [range, 20-72 years]). Six patients (8%) were university graduates. Heterosexual intercourse was the most common route of transmission (60%), followed by homosexual intercourse and intravenous drug use. Almost all women (24 out of 25; 96%) acquired the infection from their husbands. Median CD4 T-cell count at diagnosis was 302/mm3 (range, 9-1,270). On admission, CD4 T-cell count was < 200/mm3 in 39%, 200-350/mm3 in 30%, and ≯350/mL in 31%. Mean viral load at diagnosis was 1,033,871 copies/mL. Forty-four percent of the patients were admitted with obvious clinical signs and symptoms, whereas 56% were diagnosed through screening tests.

CONCLUSIONS

Poorly educated individuals and men constituted the majority of the cases. Most women acquired the disease from their husbands. Considering the poor level of education among the patients we studied, effective educational programs should be developed to reduce the transmission of HIV. Although heterosexual intercourse was the most common route of transmission, 38% of the patients we studied reported male-to-male intercourse. This is markedly higher than the 9% rate of transmission by this route in Turkey.
