Cascade of care and factors associated with virological suppression among HIV-positive persons linked to care in the Test and Keep in Care (TAK) project

Has COVID-19 Changed the Incidence and Profile of Late Presenters for HIV Infection in Lodz, Polish Reference Centre, Poland?

Objectives: The aim of this study was to compare the prevalence and characteristics of HIV late presenters (LPs) and advanced LPs (aLPs) registered in the Lodz HIV centre during the COVID-19 pandemic (2020-2021) with those of the pre-pandemic period (2017-2019). Methods: A retrospective analysis was performed of the predictive factors associated with HIV LPs and aLPs based on multivariable logistic regression. The patient entry into specialist HIV care after diagnosis during the pandemic was analysed. Results: Of 121 newly diagnosed HIV infections during the pandemic, 49.6% had late presentation and 36.4% had advanced HIV disease (AHD). In the pre-pandemic period, out of 154 newly diagnosed patients, 58.4% were LPs and 38.3% were aLPs. Independent risk factors for HIV late presentation were older age (OR: 1.04, 95% CI: 1.01-1.076; p = 0.008), diagnosis in hospital (OR: 5.63, 95% CI: 2.87-11.05; p < 0.001) and negative VDRL as compared to positive VDRL (OR: 2.48, 95% CI: 1.19-5.15; p = 0.015). The same predictive factors were associated with aLPs: older age (OR: 1.07, 95% Cl 1.04-1.11; p < 0.001), HIV diagnosis in hospital (OR: 4.25, 95% CI 2.17-8.29; p < 0.001) and negative VDRL as compared to positive VDRL (OR: 4.95, 95% CI 1.87-13.10; p = 0.001). HIV diagnosis during the pandemic was not a risk factor for late presentation nor for advanced late presentation. However, the time between HIV diagnosis and the first visit to an HIV centre was statistically lower in the pre-pandemic period (p = 0.0048); the median lengths of time between the date of HIV testing, the first visit to the centre and the initiation of ART did not differ between these two periods in LPs and aLPs (p > 0.05). Conclusions: The COVID-19 pandemic did not change the prevalence or characteristics of late presentation and aLPs among newly diagnosed patients, nor did it extend the time to enrolment in HIV care or ART introduction in these groups.

Transmitted HIV drug resistance and subtype patterns among blood donors in Poland

Surveillance on the HIV molecular variability, risk of drug resistance transmission and evolution of novel viral variants among blood donors remains an understudied aspect of hemovigilance. This nationwide study analyses patterns of HIV diversity and transmitted resistance mutations. Study included 185 samples from the first time and repeat blood donors with HIV infection identified by molecular assay. HIV protease, reverse transcriptase and integrase were sequenced using population methods. Drug resistance mutation (DRM) patterns were analyzed based on the Stanford Interpretation Algorithm and standardized lists of transmitted mutations. Phylogeny was used to investigate subtyping, clustering and recombination patterns. HIV-1 subtype B (89.2%) followed by subtype A6 (7.6%) were predominant, while in three (1.6%) cases, novel recombinant B/A6 variants were identified. Non-B variants were more common among repeat donors (14.5%) compared to the first time ones (1.8%), p = 0.011, with higher frequency (9.9%) of A6 variant in the repeat donor group, p = 0.04. Major NRTI DRMs were observed in 3.8%, NNRTI and PI in 0.6% and INSTI 1.1% of cases. Additionally, E157Q polymorphism was observed in 9.8% and L74I in 11.5% of integrase sequences. Transmission of drug resistance among blood donors remains infrequent. Subtype patters increase in complexity with emergence of novel intersubtype A6B recombinants.

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.
