Changes in Cytokine Levels After Dextrose Injection in Stage IV Knee Osteoarthritis

August 10, 2022 updated by: Gaston Andres Topol, Fisiatria y Traumatología

Changes in Cytokines After Masked Intraarticular Injection of Dextrose or Aspiration Only in Stage IV Knee Osteoarthritis

Twenty participants with severe arthritis will be enrolled. For the first week participants will either be injected with dextrose or just have fluid withdrawn for testing. The remaining participants will be given dextrose injection at the end of the week. After one week dextrose injections will be given at one, two, three, four, five, and six months. Fluid will be withdrawn from the knee at time zero, one week, and three months. The hypothesis is that dextrose injection will cause a change in proteins in the knee consistent with improved repair signals, along with improving knee pain and function. .

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

Participants with stage IV knee osteoarthritis will be evaluated for eligibility and randomized 1 to 1 using an Internet randomization method to ensure random allocation.

At time zero all participants will receive aspiration of their knees from the suprapatellar pouch of 5.5 mL of synovial fluid for cytokine analysis. After that 10 of the participants will receive injection of 10 mL of 12.5% dextrose. The other 10 will receive no injection after aspiration. Pain levels will be measured at time zero, 15 minutes, two hours and 48 hours after aspiration with or without injection to gather information about the time course of analgesia.

At one week all participants will receive aspiration of 2.0 mL from the suprapatellar pouch for cytokine analysis, followed by injection of the remaining 10 participants with dextrose 12.5%. Pain levels will be measured at the same time intervals to complete evaluation of dextrose analgesia.

After two weeks injections will be open label with 10 mills of dextrose 12 and have percent injected at one, two, three, four, five, and six months. At the three month. Another 2 mL of synovial fluid will be sent to the laboratory for cytokine analysis.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

21 years to 75 years (Adult, Older Adult)

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.
