Ischemia Modified Albumin (IMA) Expression in the Male and Female Population (IMAandGENDER)

September 5, 2016 updated by: Giovanni Bracci, Istituto Ortopedico Rizzoli
The study has as general objective to analyze in the adult population, (male and female) the presence of a very common protein, in its normal form and modified, isolated from the blood of patients and called albumin. The opportunity to observe the distribution of this protein in the population, provides the basis to be able to perform this type of assay also in the population of patients with pathologies, in the near future, with the aim of increasing knowledge on the subjective tolerability to orthopedic implants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

100 patients, waiting for elective surgical intervention (such as hip replacement or primary knee ligament reconstruction, arthroscopy), distributed evenly by gender and age (50 men, 50 women including 25 postmenopausal and 25 in bearing age) and afferent to the Department of Surgery Prosthetic hip and knee of our Institute, will be enrolled. At execution time of blood sampling routine, a further specimen of whole blood (7 ml) will be added which will be sent to the Medical technology laboratory for IMA dosage. In addition, total albumin, ferritin, transferrin and serum iron will be analyzed from clinical pathological laboratory. The investigators will be able to analyze the IMA and normalized IMA distributions with respect to gender factor and correlation with the three listed blood tests (ferritin, transferrin and serum iron).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
IMA dosage
Time Frame: one year
Dosage of IMA (mg/ml), with ELISA assay for each patient
one year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
iron, transferrin dosages
Time Frame: one year
Dosage of iron and transferrin (mg/ml) values in patients blood
one year
Ferritin dosages
Time Frame: one year
Dosage of ferritin (ng/ml) values in patients blood
one year
