Spanish Cohort of Patients With HIV Infection Older Than 50 Years for the Study of Fragility and Physical Function
- Conditions
- HIV InfectionsFrail Older Adults
- Registration Number
- NCT03558438
- Lead Sponsor
- Fundacion SEIMC-GESIDA
- Brief Summary
It's a prospective observational study to assess frailty and physical function
- Detailed Description
We stimate to recruit 1120 patients older tan 50 years to assess frailty and define a simplified fragility index
Recruitment & Eligibility
- Status
- ACTIVE_NOT_RECRUITING
- Sex
- All
- Target Recruitment
- 802
-
Patients with confirmed HIV + infection.
-
Patients aged ≥ 50 years at the time of starting the study, followed in the Infectious-HIV consultations of the centers participants.
This limit has been chosen because it is accepted by the scientific community for define the elderly patient in patients with HIV infection.
-
Have signed the informed consent and be willing to comply with the study visits.
- Have an established disability that does not allow you to walk.
- Patients who can not comply with the visits and study procedures or who are not usually followed at the center.

- Primary Outcome Measures
Name Time Method To study the prognostic value of the CD4 / CD8 ratio in relation to frailty Change from Basal to Year 5 Analyze the relationship between exposure time to different families of antiretroviral drugs with fragility. Change from Basal to Year 5 To know the prevalence of frailty in the population over 50 years old with HIV infection according to Fried's fragility phenotype Change from basal to year 5 Fragility is defined according to the 5 Fried criteria:
* Involuntary weight loss: (\> 4.5Kg in the last year)
* Declined mood: through two questions from the Scale for Depression of the Center for Epidemiological Studies (CES-D).
* Speed of walking adjusted for height and sex,
* Weekly physical activity adjusted by sex.
* Muscle weakness according to manual grip strength adjusted for BMI and sex.Define fragility biomarkers Change from Basal to Year 5 immunological profile, oxidative damage, microbiome.
Define a new simplified fragility index for the elderly patients with HIV infection easily applicable in clinical routine practice Year 5 The simplified fragility index for the elderly patient with HIV infection can not be defined a priori, so a multivariate logistic regression analysis will be performed for those variables that are associated with fragility in the analysis univariate, which will allow us to determine the variables that are associated in a independent with fragility, which will be with which we will define the fragility index simplified. Fragility will be treated as a binary variable: pre-fragile and robust will form a group that will serve as control. The fragility phenotype defined by the 5 Fried criteria will be considered the gold standard test to measure fragility when validating the simplified fragility screening test specific for elderly patients with HIV infection that we want to define
- Secondary Outcome Measures
Name Time Method Analyze the possible association of fragility in this population group with the comorbidity and the presence of other geriatric syndromes Year 1, year 2, year 3, year 4 and year 5 To know the prevalence of other geriatric syndromes Year 1, year 2, year 3, year 4 and year 5 polypharmacy, falls, cognitive impairment, depression, risk of malnutrition.
To know the risk of fragility fractures in the population over 50 years old with HIV infection in our cohort Year 1, year 2, year 3, year 4 and year 5 Know the functional situation and the risk of functional deterioration of the population over 50 years of age with HIV infection in our cohort Year 1, year 2, year 3, year 4 and year 5 To analyze the possible association of bone fragility with the presence of the syndrome clinical of fragility in this population group Year 1, year 2, year 3, year 4 and year 5
