Trial summary

The purpose of this study is to determine the risk factors associated with the occurrence of arterial insufficiency in patients with HIV / AIDS, and to identify the prevalence of this disease.

About this study

Official title: Prevalence and Risk Factors of Arterial Insufficiency in Patients With HIV / AIDS

The purpose of this study is to determine the risk factors associated with the occurrence of arterial insufficiency in patients with HIV / AIDS, and to identify the prevalence of this disease. The estimated prevalence is 10%, similar to that reported in the general population.

Read the detailed description

A case study nested in a cohort of patients with HIV / AIDS at Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico, with a cohort of 1500 patients , a sample size of 206 individuals was calculated. Data collection was performed in a prospective cross shape.

During the interview, written informed consent for inclusion in the study, along with a standard query of vascular surgery in which the patient's history as well as cardiovascular risk factors. Also, a vascular physical examination including palpation of pulses in upper and lower extremities (brachial, radial, ulnar, femoral, popliteal, posterior tibial and dorsalis pedis), femoral murmurs search and determining ankle / brachial indexes with a standardized method.

In determining the ABI was counted with a Doppler ultrasound 8 mHz, transducer gel and a sleeve for manual measurement of blood pressure, 20% longer than the largest diameter of the arm circumference.

If the patient is diagnosed with, symptomatic or asymptomatic arterial insufficiency, ABI measurements were performed at rest and effort, plus pressure index finger-arm or plethysmography. Patients with altered rates were followed in vascular surgery care.

The data were recorded in a single database unique protected by password. The results were analyzed using the statistical program STATA v 9.0.

    Defined as the last digit of HDL-C in patient serum, which is less than 50 mg / dL.

    Measured: 1 time

  7. Hypertension (High blood pressure)

    Defined as diagnosis in previous notes or use of antihypertensives.

    Measured: 1 time

Questions about this trial

What is this clinical trial studying?

An observational study of Arterial Insufficiency and Acquired Immunodeficiency Syndrome, run by Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran at 1 site in Mexico.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Arterial insufficiency (time frame: 1 time). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02264509, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2016; AzTrials last refreshed its copy on 31 Oct 2026.
