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

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.

The impact of socioeconomic factors on the healthcare costs of people living with HIV in Turkey

Background

This study addresses an important field within HIV research, the impact of socioeconomic factors on the healthcare costs of people living with HIV/AIDS (PLHIV). We aimed to understand how different socioeconomic factors could create diverse healthcare costs for PLHIV in Turkey.

Methods

Data were collected between January 2017 and December 2017. HIV-positive people attending the clinic who had been referred to the national ART programme from January 1992 until December 2017 were surveyed. The questionnaire collected socioeconomic data. The cost data for the same patients was taken from the electronic database Probel Hospital Information Management System (PHIMS) for the same period. The PHIMS data include costs for medication (highly active antiretroviral therapy or HAART), laboratory, pathology, radiology, polyclinic, examination and consultation, hospitalisation, surgery and intervention, blood and blood products, supplies and other costs. Data were analysed using STATA 14.2 to estimate the generalised linear model (GLM).

Results

The findings of our GLM indicate that age, gender, marital and parental status, time since diagnosis, employment, wealth status, illicit drug use and CD4 cell count are the factors significantly related to the healthcare cost of patients. We found that compared with people who have AIDS (CD4 cells < 200 cells/mm³), people who have a normal range of CD4 cells (≥ 500 cells/mm³) have $1046 less in expenditures on average. Compared to younger people (19–39 years), older people (≥ 55) have $1934 higher expenditures on average. Costs are $644 higher on average for married people and $401 higher on average for people who have children. Healthcare costs are $518 and $651 higher on average for patients who are addicted to drugs and who use psychiatric drug(s), respectively. Compared to people who were recently diagnosed with HIV, people who were diagnosed ≥10 years ago have $743 lower expenditures on average.

Conclusion

Our results suggest that in addition to immunological status, socioeconomic factors play a substantial role in the healthcare costs of PLHIV. The key factors influencing the healthcare costs of PLHIV are also critical for public policy makers, healthcare workers, health ministries and employment community programs.

Evaluation of Nursing Practice in Patients With HIV/AIDS With the Omaha System Electronic-Based Information Program: A Retrospective Study

The Omaha System is a standardized health care terminology that has been used in many different settings for nursing care worldwide for more than 20 years. In Turkey, it has been used mainly in nursing education and research. In this context, the purpose of this study was to examine paper-based nursing care plans of inpatients with HIV/AIDS according to the Omaha System and to assess the clinical suitability of the Omaha System. The study has a descriptive-retrospective design and was carried out at the Department of Infectious Diseases and Clinical Microbiology in a hospital. The sample consisted of 30 patients with HIV/AIDS who were chosen randomly from patients hospitalized between January 2007 and April 2017. Nursing care plans were reevaluated and encoded according to the Omaha System. The five most frequently diagnosed problems were oral health (27.2%), neuromusculoskeletal function (20.2%), communicable/infectious condition (19.4%), skin condition (13.2%), and circulation (5.7%). A total of 4409 nursing interventions were applied to solve the problems, and almost 74% of the interventions were categorized in the surveillance. Among the targets, physical signs/symptoms were indicated for more than 68% (3.026). The results confirmed the clinical suitability of the Omaha System.

Late presentation among patients with human immunodeficiency virus infection in Turkey

OBJECTIVE

Late presentation of the patients with human immunodeficiency virus (HIV) infection is associated with less favourable treatment responses, more accelerated clinical progression, and a higher mortality risk. Although HIV prevalence is low in Turkey, it is steadily increasing and the information about late presentation among HIV-positives is limited. We aimed to analyze the status of late presentation among HIV-positive patients in Turkey.

METHODS

All newly diagnosed HIV/AIDS patients from 2003 to 2016 were enrolled in this study by five dedicated centres in Istanbul, Turkey. Demographic data, CD4+ counts, and HIV RNA were collected from medical records and were transferred to a HIV database system. Late pre- sentation was defined as presentation for care with a CD4 count &lt; 350 cells/mm³ or presentation with an AIDS-defining event, regardless of the CD4 cell count. A medical literature search was done for the analysis of late presentation in Turkey.

RESULTS

The cohort included 1,673 patients (1,440 males, median age 35 years). Among them, 847 (50.6%) had an early diagnosis, with a CD count of more than 350 cells/mm³. The remaining 826 were late presenters. Among late presenters, 427 (25.5% of all, 51.7% of late presenters) presented with advanced HIV disease. Late presenters were more elderly and less educated. The gender seemed comparable between groups. Late presentation was more likely among married patients. Early presenters were more likely among homosexuals, those diagnosed in screening studies, and in lower HIV-RNA viral load category. There has been a decreasing trend among late presenters in 2011-2016 when compared to 2003-2011 period.

CONCLUSION

Current data suggest that half of HIV-infected patients present late in Turkey. In our cohort, those presented late were more elderly, less educated, married and had heterosexual intercourse. On admission, late presenters had more HIV-related diseases and were more likely in higher HIV-RNA category. In the cohort, men having sex with men were less likely late presenters. Efforts to reduce the proportion of late presentation are essential for almost every country. The countries should identify the risk factors of late presentation and should improve early diagnosis and presentation for HIV care.

Real world survival data of a rare malignancy: Anal cancer results in HIV negative patients from Turkey

BACKGROUND/AIMS

An organ preservation approach using chemoradiotherapy has been established for anal cancer. This retrospective cohort study aimed to define the clinico-demographic characteristics and outcomes of cases of human immunodeficiency virus (HIV)-negative anal carcinoma during a period of 20 years in a single comprehensive cancer institute.

MATERIALS AND METHODS

This was a single-center retrospective cohort study of patients who were treated between January 1995 and January 2015. The primary outcome measures that were investigated included overall survival (OS), progression-free survival (PFS), colostomy rates, and colostomy-free survival (CFS).

RESULTS

A total of 28 patients who were principally treated with standard 5-fluorouracil + mitomycin combination chemoradiotherapy were eligible for analysis. The 3- and 5-year PFS rates were 92.4% and 63%, respectively. The lower T stage was found to be associated with a prolonged PFS (p=0.001). The 3- and 5-year CFS rates were 84.3% and 74.9%, respectively. A longer CFS was observed with lower T stages (p=0.05). At the last follow-up, 75% of the patients with anal cancer were alive, and 71.4% of the patients were disease free. The median OS was not reached with a median follow-up of 54 months (range, 6-115 months). The 3- and 5-year OS rates were 82% and 71.1%, respectively. No late toxicity was observed during the follow-up period.

DISCUSSION

The short- and long-term prognoses of HIV-negative patients with anal squamous cell carcinoma were good, and low-grade toxicity was rare, thereby demonstrating that these patients can be successfully treated in a real-life setting with favorable outcomes.

Proportion and factors associated with recent HIV infection in a cohort of patients seen for care in Italy over 1996-2014: Data from the ICONA Foundation Study cohort

In Italy the prevalence of recent HIV infection (RHI) isn't currently monitored. Early diagnosis is crucial to allow introduction of antiretroviral therapy (cART) in the recent phase of infection. We aimed to estimate the proportion and the determinants of RHI among patients enrolled in the ICONA cohort; we explored differences in the median time from HIV diagnosis to cART initiation and in the viro-immunological response between RHI and Less Recent HIV infections (NRHI). We included antiretroviral-naïve HIV-positive patients enrolled in the cohort with documented dates of HIV-negative and positive antibodies tests, grouped in RHI (estimated date of seroconversion within 12 months of enrolment) and NRHI. Proportion of RHI and the trend of this proportion by calendar period (1996-2014) were investigated (Chi-square test). Logistic regression analysis was employed to identify factors associated with RHI. The time from seroconversion to cART initiation was compared in RHI and NRHI overall and after stratification by calendar period (survival analysis). We finally explored the time from starting cART to HIV-RNA <50 copies/mL and to CD4+ gain ≥200 cells/mmc by Cox regression. HIV seroconversion could be estimated for 2608/12,616 patients: 981/2608 (37.6%) were RHI. Proportion of RHI increased in recent calendar periods and was associated with younger age, baseline higher HIV-RNA and CD4+ count. There wasn't difference in the 2-year estimates of cART start between RHI and NRHI, regardless of calendar period. Rates and hazards of virological response were similar in RHI versus NRHI. RHI showed a 1.5-fold higher probability of CD4+ gain, also following adjustment for calendar period and cART regimen, and for age, HCV and smoking; the difference in probability was however attenuated after further controlling for baseline HIV-RNA and CD4+ T-cells. The increased proportion of RHI over time suggests that in recent years in Italy HIV infections are more likely to be detected earlier than before. The similar rates of cART introduction and viro-immunological response in RHI and NRHI probably reflect the efficacy of the modern cART regimens. An improvement of the prevention services is warranted to allow an early cART access, also in the perspective of therapy as prevention.

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.
