Immunoaging at Early Ages Could Drive a Higher Comorbidity Burden in People with HIV on Antiretroviral Therapy Compared with the Uninfected Population.

This is an observational, cross-sectional, comparative case-control, pilot study aimed at assessing the impact of HIV infection and age on immunological markers in people with HIV (PWH) on antiretroviral therapy (ART). The study included 40 PWH on ART, divided into two age groups (40-45 years vs. ≥60 years), and 30 HIV-uninfected controls matched by sex and age. The results show that older PWH on ART had more comorbidities and a higher frequency of CD8 T cells compared to older controls, with a significant decrease in CD8 naïve T cells with age. Additionally, younger PWH on ART exhibited higher frequencies of activated CD8 T cells and elevated levels of inflammatory markers (sCD14, IL-6) compared to age-matched controls, with values similar to those of older PWH on ART. These findings suggest that younger PWH on ART may experience accelerated immunoaging, highlighting the need for early interventions in this population.

Identifying the needs of older people living with HIV (≥ 50 years old) from multiple centres over the world: a descriptive analysis.

BACKGROUND: Older People Living with HIV (OPWH) combine both aging and HIV-infection features, resulting in ageism, stigma, social isolation, and low quality of life. This context brings up new challenges for healthcare professionals, who now must aid patients with a significant comorbidity burden and polypharmacy treatments. OPWH opinion on their health management is hardly ever considered as a variable to study, though it would help to understand their needs on dissimilar settings. METHODS: We performed a cross-sectional, comparative study including patients living with HIV aged ≥50 years old from multiple centers worldwide and gave them a survey addressing their perception on overall health issues, psychological problems, social activities, geriatric conditions, and opinions on healthcare. Data was analyzed through Chisquared tests sorting by geographical regions, age groups, or both. RESULTS: We organized 680 participants data by location (Center and South America [CSA], Western Europe [WE], Africa, Eastern Europe and Israel [EEI]) and by age groups (50- 55, 56-65, 66-75, >75). In EEI, HIV serostatus socializing and reaching undetectable viral load were the main problems. CSA participants are the least satisfied regarding their healthcare, and a great part of them are not retired. Africans show the best health perception, have financial problems, and fancy their HIV doctors. WE is the most developed region studied and their participants report the best scores. Moreover, older age groups tend to live alone, have a lower perception of psychological problems, and reduced social life. CONCLUSIONS: Patients' opinions outline region- and age-specific unmet needs. In EEI, socializing HIV and reaching undetectable viral load were the main concerns. CSA low satisfaction outcomes might reflect high expectations or profound inequities in the region. African participants results mirror a system where general health is hard to achieve, but HIV clinics are much more appealing to them. WE is the most satisfied region about their healthcare. In this context, age-specific information, education and counseling programs (i.e. Patient Reported Outcomes, Patient Centered Care, multidisciplinary teams) are needed to promote physical and mental health among older adults living with HIV/AIDS. This is crucial for improving health-related quality of life and patient's satisfaction.

Prevalence, progression, and management of advanced chronic kidney disease in a cohort of people living with HIV.

BACKGROUND: Advanced kidney disease is an emerging problem in people living with HIV despite sustained viral suppression. METHODS: We performed a prospective cohort study to identify people living with HIV with advanced kidney disease according to the Kidney Disease Improving Global Outcomes criteria and to assess disease progression over a 48-week period following the offer of targeted multidisciplinary management. RESULTS: From our cohort of 3090 individuals, 55 (1.8%, 95% confidence interval [CI] 1.31-2.25) fulfilled the inclusion criteria. Most were male (83.6%), and the median (interquartile range [IQR]) age was 58 (53.25-66.75) years. Nadir CD4 T-cell count was 135.5 (IQR 43.5-262.75) cells/µl, current CD4 T-cell count was 574 (IQR 438.5-816) cells/µl, and 96% had maintained HIV viral suppression. The most frequent comorbidity was arterial hypertension (85.5%). Inadequate antiretroviral dose was detected in three individuals (5.5%), and drug-drug interactions were recorded in eight (14.5%), mainly involving the use of cobicistat (n = 5 [9%]). Four individuals (7%) required modification of their concomitant treatment. Seven (13%) had to start or resume follow-up with a nephrologist. Nine participants (16.4%) experienced an improvement in kidney disease stage, three individuals (5.5%) underwent renal transplantation, and one (2%) started haemodialysis. CONCLUSIONS: Our results show that a multidisciplinary approach, including a critical review of treatment and evaluation of specific requirements, could be useful for anticipating drug-drug interactions and toxicities and for reducing death and hospitalization in people living with HIV with advanced kidney disease.

Accentuated aging associated with HIV in a Mediterranean setting occurs mainly in persons aged>70 years: a comparative cohort study (Over50 cohort).

In an ongoing Mediterranean cohort, we compared age-related conditions between 208 HIV-infected persons and 104 matched controls. ≥3 comorbidities were found in 31.0% of HIV-infected patients and 8.7% of controls. Conditions significantly more frequent among the HIV-infected population were: lipid abnormalities, cancer, osteopenia/osteoporosis, liver disease, sexual dysfunction, hearing deficit, sleep disorders, falls, cognitive complaints, being single, living alone, and being elderly at risk. HIV-infected patients aged >70 years had a significantly higher number of cardiovascular risk factors (CVRF) and comorbidities than controls. HIV-infected persons who had never smoked had a higher prevalence of CVRFs, ≥3 comorbidities, liver disease, cancer, and cognitive complaints compared to controls. Factors associated with frailty were being a man who has sex with men, ≥3 CVRFs, nadir CD470 years. The multidisciplinary assessment also revealed concerning findings in social, cognitive, and functional variables among HIV-infected individuals, with a higher prevalence of elderly at risk than among controls.

Potential prescribing issues among older HIV-infected subjects in a Mediterranean cohort: Does the current prevalence give cause for concern?

AIMS: To determine the prevalence of potential prescribing issues (PPI) in HIV-infected subjects aged ≥65 years according to the Beers and STOPP/START criteria and antiretroviral drug-drug interactions (Liverpool website). Secondary objectives were to assess the concordance between Beers and STOPP/START criteria in our population, and to identify the drugs most frequently involved in PPI. METHODS: Cross-sectional cohort study based on a systematic review of the electronic drug prescriptions confirmed by an interview of 91 HIV-infected patients aged ≥65 years. Discrepancies between prescription criteria were assessed using crosstabs and compared using the χ2 test or Fisher exact test. RESULTS: The mean age was 72.1 (5.6) years, 75.8% had ≥3 comorbidities and 59.3% polypharmacy. PPI were identified in 87.9%: 71.4% by STOPP/START and 45.1% by Beers. Comparing both criteria, 56.9% of PPI by STOPP/START were detected by Beers, while 92.5% of those detected by the Beers criteria were detected by STOPP/START (P < .001). Amber/red flag interactions between antiretrovirals and comedications were found in 45.1%: 3 severe (red) in 2 patients (2.2%). The most frequent drugs involved in PPI were benzodiazepines (>30%). Cobicistat was the drug most frequently involved in potential interactions (42.2%). CONCLUSION: The prevalence of PPI among older HIV-infected persons gives cause for concern, as it is almost 90%. Optimization strategies, including a critical review of the treatment plan, should be implemented in clinical routine by a multidisciplinary team, in particular in patients with multiple comorbidities and polypharmacy. The STOPP/START criteria seem to detect more PPI, mainly for European populations.

A Specific Mobile Health Application for Older HIV-Infected Patients: Usability and Patient's Satisfaction.

Background: HIV infection is an increasingly complex chronic disease associated with numerous medical, psychological, and social problems. The life expectancy of affected patients has increased considerably. Medical apps could also play a role in prevention and management of comorbid conditions in the HIV-infected population. Objectives: To determine the usefulness of an app designed specifically for HIV-infected patients aged 60 years or older and to assess changes in patient satisfaction, adherence to treatment, and quality of health care. Methods: A randomized clinical trial was conducted, including 100 patients (50 per group): (1) an experimental group comprising patients using the app + routine medical care (app group) and (2) with routine medical care (control group). The usability of the app and patient satisfaction were evaluated in the app group at week 48. Quality of life, adherence to treatment, and clinical parameters were compared between both groups at 48 weeks, as well as the number of face-to-face visits. Results: We found that 52.2% and 73.8% of patients in the app group used the app at weeks 24 and 48, respectively. Patients used the app for a mean of 23.7 (±2.84) days over the 48 weeks. The most visited screens were health counseling and medical records (24.8% and 22.2%, respectively). At week 48, 85.2% of patients thought that the app was useful and 91.4% would recommend the app to friends or relatives. The app was well valued by participants (4.79 [±0.21] of 5.00) and 64.6% thought that the app improved their health care.

Vagus nerve dysfunction in the post-COVID-19 condition: a pilot cross-sectional study.

OBJECTIVES: The post-COVID-19 condition (PCC) is a disabling syndrome affecting at least 5%-10% of subjects who survive COVID-19. SARS-CoV-2 mediated vagus nerve dysfunction could explain some PCC symptoms, such as dysphonia, dysphagia, dyspnea, dizziness, tachycardia, orthostatic hypotension, gastrointestinal disturbances, or neurocognitive complaints. METHODS: We performed a cross-sectional pilot study in subjects with PCC with symptoms suggesting vagus nerve dysfunction (n = 30) and compared them with subjects fully recovered from acute COVID-19 (n = 14) and with individuals never infected (n = 16). We evaluated the structure and function of the vagus nerve and respiratory muscles. RESULTS: Participants were mostly women (24 of 30, 80%), and the median age was 44 years (interquartile range [IQR] 35-51 years). Their most prevalent symptoms were cognitive dysfunction 25 of 30 (83%), dyspnea 24 of 30 (80%), and tachycardia 24 of 30 (80%). Compared with COVID-19-recovered and uninfected controls, respectively, subjects with PCC were more likely to show thickening and hyperechogenic vagus nerve in neck ultrasounds (cross-sectional area [CSA] [mean ± standard deviation]: 2.4 ± 0.97mm2 vs. 2 ± 0.52mm2 vs. 1.9 ± 0.73 mm2; p 0.08), reduced esophageal-gastric-intestinal peristalsis (34% vs. 0% vs. 21%; p 0.02), gastroesophageal reflux (34% vs. 19% vs. 7%; p 0.13), and hiatal hernia (25% vs. 0% vs. 7%; p 0.05). Subjects with PCC showed flattening hemidiaphragms (47% vs. 6% vs. 14%; p 0.007), and reductions in maximum inspiratory pressure (62% vs. 6% vs. 17%; p ≤ 0.001), indicating respiratory muscle weakness. The latter findings suggest additional involvement of the phrenic nerve. DISCUSSION: Vagus and phrenic nerve dysfunction contribute to the complex and multifactorial pathophysiology of PCC.

Disseminated tuberculosis and diagnosis delay during the COVID-19 era in a Western European country: a case series analysis.

Background: Disseminated tuberculosis is frequently associated with delayed diagnosis and a poorer prognosis. Objectives: To describe case series of disseminated TB and diagnosis delay in a low TB burden country during the COVID-19 period. Methodology: We consecutively included all patients with of disseminated TB reported from 2019 to 2021 in the reference hospital of the Northern Crown of the Metropolitan Area of Barcelona. We collected socio-demographic information, clinical, laboratory and radiological findings. Results: We included all 30 patients reported during the study period-5, 9, and 16 in 2019, 2020, and 2021 respectively-20 (66.7%) of whom were male and whose mean age was 41 years. Twenty-five (83.3%) were of non-EU origin. The most frequent system involvement was central nervous system (N = 8; 26.7%) followed by visceral (N = 7; 23.3%), gastro-intestinal (N = 6, 20.0%), musculoskeletal (N = 5; 16.7%), and pulmonary (N = 4; 13.3%). Hypoalbuminemia and anemia were highly prevalent (72 and 77%). The median of diagnostic delay was 6.5 months (IQR 1.8-30), which was higher among women (36.0 vs. 3.5 months; p = 0.002). Central nervous system involvement and pulmonary involvement were associated with diagnostic delay among women. We recorded 24 cured patients, two deaths, three patients with post-treatment sequelae, and one lost-to-follow up. We observed a clustering effect of patients in low-income neighborhoods (p < 0.001). Conclusion: There was a substantial delay in the diagnosis of disseminated TB in our study region, which might impacted the prognosis with women affected more negatively. Our results suggest that an increase in the occurrence of disseminated TB set in motion by diagnosis delay may have been a secondary effect of the COVID-19 pandemic.

Determinants of the onset and prognosis of the post-COVID-19 condition: a 2-year prospective observational cohort study.

Background: At least 5-10% of subjects surviving COVID-19 develop the post-COVID-19 condition (PCC) or "Long COVID". The clinical presentation of PCC is heterogeneous, its pathogenesis is being deciphered, and objective, validated biomarkers are lacking. It is unknown if PCC is a single entity or a heterogeneous syndrome with overlapping pathophysiological basis. The large US RECOVER study identified four clusters of subjects with PCC according to their presenting symptoms. However, the long-term clinical implications of PCC remain unknown. Methods: We conducted a 2-year prospective cohort study of subjects surviving COVID-19, including individuals fulfilling the WHO PCC definition and subjects with full clinical recovery. We systematically collected post-COVID-19 symptoms using prespecified questionnaires and performed additional diagnostic imaging tests when needed. Factors associated with PCC were identified and modelled using logistic regression. Unsupervised clustering analysis was used to group subjects with PCC according to their presenting symptoms. Factors associated with PCC recovery were modelled using a direct acyclic graph approach. Findings: The study included 548 individuals, 341 with PCC, followed for a median of 23 months (IQR 16.5-23.5), and 207 subjects fully recovered. In the model with the best fit, subjects who were male and had tertiary studies were less likely to develop PCC, whereas a history of headache, or presence of tachycardia, fatigue, neurocognitive and neurosensitive complaints and dyspnea at COVID-19 diagnosis predicted the development of PCC. The cluster analysis revealed the presence of three symptom clusters with an additive number of symptoms. Only 26 subjects (7.6%) recovered from PCC during follow-up; almost all of them (n = 24) belonged to the less symptomatic cluster A, dominated mainly by fatigue. Recovery from PCC was more likely in subjects who were male, required ICU admission, or had cardiovascular comorbidities, hyporexia and/or smell/taste alterations during acute COVID-19. Subjects presenting with muscle pain, impaired attention, dyspnea, or tachycardia, conversely, were less likely to recover from PCC. Interpretation: Preexisting medical and socioeconomic factors, as well as acute COVID-19 symptoms, are associated with the development of and recovery from the PCC. Recovery is extremely rare during the first 2 years, posing a major challenge to healthcare systems. Funding: Fundació Lluita contra les Infeccions.

A randomized pilot trial to evaluate the benefit of the concomitant use of atorvastatin and Raltegravir on immunological markers in protease-inhibitor-treated subjects living with HIV.

OBJECTIVE: Optimization of antiretroviral therapy and anti-inflammatory treatments, such as statins, are among the strategies aimed at reducing metabolic disorders, inflammation and immune activation in people living with HIV (PLWH). We evaluated the potential benefit of combining both strategies. DESIGN: Forty-two PLWH aged ≥40 years receiving a protease inhibitor (PI)-based regimen were randomized (1:1) to switch from PI to Raltegravir (n = 20), or to remain on PI (n = 22). After 24 weeks, all patients received atorvastatin 20mg/day for 48 weeks. METHODS: We analyzed plasma inflammatory as well as T-cell maturation, activation, exhaustion and senescence markers at baseline, 24 and 72 weeks. RESULTS: Plasma inflammatory markers remained unchanged. Furthermore, no major changes on T-cell maturation subsets, immunoactivation, exhaustion or immunosenescence markers in both CD4 and CD8 T cell compartments were observed. Only a modest decrease in the frequency of CD38+ CD8 T cells and an increase in the frequency of CD28-CD57+ in both CD4 and CD8 T-cell compartments were noticed in the Raltegravir-switched group. CONCLUSIONS: The study combined antiretroviral switch to Raltegravir and Statin-based anti-inflammatory strategies to reduce inflammation and chronic immune activation in PLWH. Although this combination was safe and well tolerated, it had minimal impact on inflammatory and immunological markers. CLINICAL TRIALS REGISTRATION: NCT02577042.
