Excess liver-related mortality among people with AIDS compared to the general population: an Italian nationwide cohort study using multiple causes of death

The sex differences in diseases progression and prognosis among persons with HIV and HBV coinfection

To investigate sex differences in liver disease development and prognosis in individuals with HIV and HBV co-infection. This study comprised 752 HIV/HBV co-infected people who were diagnosed with HIV and started on combination antiretroviral therapy (cART) between January 31st, 2015 and January 31st, 2023. Their clinical data, including CD4+ T lymphocyte counts, HBV-DNA, and FIB-4 scores, were tracked once a year. The prognosis was determined during the long-term surveillance period. Risk factors related with the progression of liver diseases were included in both univariable and multivariable logistic regression. Then, sex differences in CD4+ T lymphocyte counts, HBV-DNA, FIB-4 scores, changes in liver fibrosis levels, and prognosis were investigated. Multivariable logistic regression analysis identified male as an independent risk factor for liver disease progression. Compared to the male group, the female group had a significantly greater decline of HBV DNA levels at years 1, 2, 3, 3-5, and > 5 post-cART. At each assessment point, the female group showed a significantly greater rise in CD4+ T lymphocyte counts than the male group based on their respective baseline values. Furthermore, females had greater CD4+ T lymphocyte counts and a lower prevalence of liver cirrhosis than males throughout the study period. Compared to female, higher incidence of end-stage-liver disease (1.190/100 person-years vs 0.714/100 person-years), higher all-cause mortality (0.440/100 person-years vs 0.148/100 person-years) and higher mortality associated with end-stage-liver diseases (0.273/100 person-years vs 0.074/100 person-years) were found in male. Among individuals with HIV and HBV coinfection, males had a worse therapeutic effect of HBV-active therapy and poorer prognosis than females.

Mortality Risk Factors Among People Living with HIV Receiving Second-line Antiretroviral Therapy in Rural China

BACKGROUND

Second-line antiretroviral therapy (ART) was introduced in Henan Province in 2009. The number of people living with human immunodeficiency virus (HIV) starting this therapy is increasing.

OBJECTIVE

This study aimed to investigate the survival and factors affecting mortality among this group.

METHODS

We conducted a retrospective cohort study of people living with HIV (PLHIV) who switched to second-line ART between May 1, 2010, and May 1, 2016, using the Kaplan-Meier method and Cox proportional hazards models.

RESULTS

We followed 3,331 PLHIV for 26,988 person-years, of whom 508 (15.3%) died. The mortality rate was 1.88/100 person-years. After adjusting for confounding factors, we found being a woman (hazard ratio (HR), 0.66; 95% confidence interval (CI) 0.55-0.79), > 50 years old (HR, 2.69; 95% CI, 2.03-3.56), single/widowed (HR, 1.26; 95% CI, 1.04-1.52), having > 6 years of education (HR, 0.78; 95% CI, 0.65-0.94), Chinese medicine (HR, 0.75; 95% CI, 0.52-0.96), liver injury (HR, 1.58; 95% CI, 1.19-2.10), and CD4+ T cell count <200 cells/μl (HR, 1.94; 95% CI, 1.47-2.55), or 200-350 cells/μl (HR, 1.37; 95% CI, 1.03-1.82) were associated with mortality risk.

CONCLUSIONS

We found lower mortality among PLHIV who switched to second-line ART than most previous studies. The limitations of a retrospective cohort may, therefore, have biased the data, and prospective studies are needed to confirm the results. Moreover, Chinese medicine combined with second-line ART shows potential as a treatment for HIV.

Survival in People Living with HIV with or without Recurrence of Hepatocellular Carcinoma after Invasive Therapy

Background and Aims: To address the overall survival (OS) and recurrence (RE) in people living with HIV (PLWH) treated with invasive therapy (IT) for hepatocellular carcinoma (HCC). Methods: This is a retrospective cohort study on 41 PLWH with HCC receiving IT, defined as liver resection (LR), orthotopic liver transplantation (OLT), radiofrequency thermo-ablation (RFTA) trans arterial chemo, or radioembolization (CRE). OS and RE were investigated by Kaplan–Meier curves. The Cox proportional hazard regression model was used for multivariate analyses. Results: Recurrence occurred in 46.3% PLWH; in 36.7% of participants at 2 years and in 52% at 5 years from HCC diagnosis; it was less frequent in males, p = 0.036. Overall, 2- and 5-year survival after HCC diagnosis was 72% and 48%, respectively. Two-and five-year survival was 100% and 90.9%, respectively, in PLWH receiving OLT, compared to other IT (60.9% and 30.6%, respectively) log-rank p = 0.0006. Two- and five-year survival in participants with no-RE was 70.5% and 54.6%, respectively, and 73.7% and 42.1% among RE, respectively, log-rank p = 0.7772. By multivariate analysis, AFP at values < 28.8 ng/mL, at HCC diagnosis, was the only factor predicting survival. Conclusions: Fifty percent of PLWH survived five years after HCC diagnosis; 90.9% among OLT patients. Recurrence after IT was observed in 46% of HCC/PLWH. AFP cut-off levels of 28.8 ng/mL were the only independent variable associated with survival.

Increased kidney disease mortality among people with AIDS versus the general population: a population-based cohort study in Italy, 2006-2018

OBJECTIVES

This study aimed to assess whether an excess mortality related to kidney and other urinary tract diseases exists among Italian people with AIDS (PWA), as compared with the general population without AIDS (non-PWA).

DESIGN

Population-based, retrospective cohort study.

SETTING AND PARTICIPANTS

We conducted a nationwide study including 9481 Italian PWA, aged 15-74 years, reported to the National AIDS Registry between 2006 and 2018.

METHODS

Vital status and causes of death were retrieved by record linkage with the National Register of Causes of Death up to 2018. Excess mortality for PWA versus non-PWA was estimated through sex-standardised and age-standardised mortality ratios (SMRs) with corresponding 95% CIs.

RESULTS

Among 2613 deceased PWA, 262 (10.0%) reported at least one urinary tract disease at death, including 254 (9.7%) non-cancer diseases-mostly renal failures (225 cases, 8.6%)-and 9 cancers (0.3%). The overall SMR for non-cancer urinary tract diseases was 15.3 (95% CI 13.4 to 17.3) with statistically significant SMRs for acute (SMR=22.3, 95% CI 18.0 to 27.4), chronic (SMR=8.4, 95% CI 6.0 to 11.3), and unspecified renal failure (SMR=13.8, 95% CI 11.2 to 16.8). No statistically significant excess mortality was detected for urinary tract cancers (SMR=1.7, 95% CI 0.8 to 3.3). The SMRs were particularly elevated among PWA aged <50 years, injecting drug users, or those with the first HIV-positive test >6 months before AIDS diagnosis.

CONCLUSIONS

The excess mortality related to non-cancer kidney and other urinary tract diseases reported among PWA highlights the importance of implementing the recommendation for screening, diagnosis and management of such conditions among this population.

Incidence and mortality of non-AIDS-defining cancers among people living with HIV: A systematic review and meta-analysis

Background

Non-AIDS-defining cancers (NADCs) are now becoming a rising cause of morbidity among people living with HIV (PLHIV) in the highly active antiretroviral therapy (HAART) era. We conducted a systematic review and meta-analysis to estimate the summary risk of incidence and mortality of a wide range of NADCs among PLHIV compared with the general population.

Methods

This systematic review and meta-analysis was registered in the PROSPERO (registration number CRD42020222020). We searched PubMed, EMBASE, Cochrane library, and Web of Science for relevant studies published before Jan 24, 2022. Cohort or registry linkage studies comparing the incidence or mortality of individual NADCs in PLHIV with that in the general population were included. Studies simply reporting outcomes of cancer precursor lesions or combined NADCs were excluded. We calculated pooled standardised incidence (SIRs) and standardised mortality ratios (SMRs) and their 95% confidence intervals (CIs) using random-effects models, and used robust variance estimation to account for non-independence in study-level effect sizes.

Findings

We identified 92 publications arising from 46 independent studies including 7 articles out of 7 studies from developing countries. Among the 40 types of NADCs investigated, all of the 20 infection-related NADCs, cancers related with human papillomavirus infection in particular, and half of the 20 non-infection-related NADCs occurred in excess in PLHIV compared with the general population. This risk pattern was consistent in most WHO regions and in both high-income and low-and middle-income countries. The increased SIRs for various NADCs were more evident among PLHIV with advanced immunodeficiency, and was explored by HIV transmission route, and use of HAART. PLHIV had increased mortality for anal cancer (SMR 124·07, 95% CI 27·31-563·72), Hodgkin lymphoma (41·03, 2·91-577·88), liver cancer (8·36, 3·86-18·11), lung cancer (3·95, 1·52-10·26), and skin melanoma (3·95, 1·28-12·2).

Interpretation

PLHIV had increased incidence and mortality for a wide spectrum of NADCs. Primary prevention and effective treatment for NADCs in this population is urgently needed.

Effects of Chinese Medicine on the Survival of AIDS Patients Administered Second-Line ART in Rural Areas of China: A Retrospective Cohort Study Based on Real-World Data

Objectives

Chinese medicine (CM) improves the symptoms of patients with acquired immune deficiency syndrome (AIDS) and prolongs their survival. This real-world study aimed to evaluate the effects of CM on the survival of AIDS patients administered second-line antiretroviral therapy (ART).

Methods

We conducted a retrospective cohort study of the medical records of patients with AIDS who switched to second-line ART between January 2009 and December 2014. Patients were divided into ART and CM + ART groups. Propensity score matching (PSM) was performed to correct for biases between groups. Kaplan–Meier analysis and the log-rank test were used to compare survival rates, and Cox regression models were employed to identify factors significantly associated with survival.

Results

The study population (n = 4180) was comprised of the CM + ART group (n = 855) and the ART group (n = 3325). After 1 : 2 PSM, 855 patients in the CM + ART group and 1699 in the ART group were selected for analysis. Patients in the CM + ART group were followed for 4246.8 person-years, and the mortality rate was 2.12/100 person-years. Patients in the ART group were followed for 8381.2 person-years, and the mortality rate was 2.91/100 person-years. Cox regression model analysis revealed that patients in the CM + ART group survived significantly longer than those in the ART group (hazard ratio: 0.73 and 95% confidence interval: 0.57–0.93). Gender, age, symptoms, CD4 cell counts, and viral loads were independently associated with the survival of AIDS patients treated with second-line ART.

Conclusions

CM significantly improved the survival rate of AIDS patients treated with second-line ART.
