Acquired immune deficiency syndrome (AIDS) and late presentation in Poland - data from Test and Keep in Care (TAK) Polska project

OBJECTIVES

Late presentation (LP) at HIV diagnosis is associated with worse prognosis and an increase in the number of new infections. We analyse the proportion of patients diagnosed late and factors related to LP in Poland in 2016-2017.

METHODS

Data were obtained from 13 out of 17 HIV centres in Poland from 2016 and 2017, including date of diagnosis, age, sex, transmission route, anti-hepatitis C virus (anti-HCV), Venereal Diseases Research Laboratory (VDRL) antibodies, AIDS diagnosis, baseline HIV viral load and CD4 count.

RESULTS

Out of 1522 patients, 88.9% were male with median age of 33.6 years. Men who have sex with men (MSM) comprised 69.4% of all new infections, heterosexual route of transmission (HTX) 18.2% and injecting drug use (IDU) 4.7%. Late presenters comprised 44.8% of the study group. Factors associated with LP were female sex [odds ratio (OR) = 1.5, 95% confidence interval (95% CI): 1.09-2.08], older age (OR = 1.59, 95% CI: 1.42-1.79 per decade), route of transmission (HTX: OR = 1.96, 95% CI: 1.50-2.56; IDU: OR = 3.17, 95% CI: 1.92-5.37), positive HCV results (OR = 1.90, 95% CI: 1.23-2.95) and syphilis diagnosis (OR = 2.06, 95% CI: 2.29-3.31). Adjusting for these factors, the only independent factors associated with LP were age (OR = 1.52, 95% CI: 1.35-1.71) and route of transmission (HTX: OR = 1.73, 95% CI: 1.23-2.44; IDU: OR = 2.24, 95% CI: 1.25-4.10).

CONCLUSIONS

Late presentation in Poland follows European trends. A total of 44.8% of all newly diagnosed patients in Poland continue to present late or at the AIDS stage. Independent factors associated with LP/AIDS were older age, IDU and HTX. Patients from these groups should be targeted to improve early diagnosis and medical care.

Factors responsible for incomplete linkage to care after HIV diagnosis: preliminary results from the Test and Keep in Care (TAK) project

OBJECTIVES

Linkage to care after HIV diagnosis remains underinvestigated in Europe, yet delays in linkage to care are an important obstacle to controlling the HIV epidemic. The Test and Keep in Care (TAK) project aims to determine the prevalence of HIV-positive persons who are lost or late to care and factors associated with this.

METHODS

Data from community-based voluntary counselling and testing that occurred in 2010-2011 were linked with data from HIV clinics using unique test numbers. Persons not registered in HIV clinics were considered lost to care (LTC). For statistical analysis, nonparametric tests were used for comparison, and a multivariable logistic regression model was developed that included all variables with P<0.1 from the univariable models.

RESULTS

A total of 110 persons were diagnosed as HIV-positive: 91% lived in central Poland, 5% were female and 71% were men who have sex with men (MSM). Forty-seven (42%) persons were LTC, seven of whom did not collect their enzyme-linked immunosorbent assay (ELISA) test result. Of those who registered, 75% registered within 1 month from HIV diagnosis, and 54% were late presenters. LTC individuals were more likely to have heterosexual or bisexual orientation, to have >20 sexual partners, to not be in a relationship with an HIV-positive partner, to not use condoms, and to be taking their first HIV test. In a logistic regression model, after adjusting for these factors, using condoms in a stable relationship decreased the odds of LTC by 72% (odds ratio 0.28; confidence interval 0.11-0.67).

CONCLUSIONS

Integration into care after HIV diagnosis requires improvement. Our results suggest that broadening awareness and counselling about sexual risks may have a positive impact.
