A statement of how the project demonstrates exceptional merit in advancing the mission of Ferris State University.
Include how the project compliments and enhances other efforts on campus and how the project compliments and enhances
other efforts on campus and how the project will continue in the future.
One of the primary objectives of Ferris State University is to be involved in collaborative research activities across its campuses and
beyond. This pilot study will be a collaboration between faculties in Ferris State University, College of Pharmacy (COP) and
Michigan College of Optometry (MCO). It will enhance the research collaborative effort in this community.
The study will provide a direction for a larger study. Upon successful completion of this pilot clinical study, the investigators will
apply for NIH (National Institute of Health) funding to conduct a randomized study with a larger population sample. This will
further enhance the collaboration effort between the two colleges (MCO and COP).
Secondly, during the reaccreditation process for the College of Pharmacy there was a strong emphasis from the accreditation body
that FSU College of Pharmacy should direct their effort toward research. The success of this study will be one way of meeting the
college needs.
Third, the execution of this study has the potential to expose Doctors of Pharmacy students and Optometry to areas of research.
Interested students will actively be involved in research and students will be mentored by different investigators. This will provide
the avenue to teach the students basic principles of research design and methodology.
There is no better way to accomplish this than by mentoring students one on one in an ongoing research. This is an opportunity
that has been rarely offered to FSU PharmD students. Clinical research is an area that students least think about. Again, through
one on one mentoring, students will be able to take advantage of this opportunity.
A brief description of the project being proposed and the desired outcomes (maximum 1 page).
Objective:
The proposed study will be a 12-month pilot study demonstrating the role of alpha lipoic acid in patients who have moderate nonproliferative diabetic retinopathy. The primary aim of this study is to test the hypothesis that the addition of alpha lipoic acid in a
diabetic patient’s therapeutic regimen can decrease the progression of diabetic retinopathy and preserve visual acuity.
Methods: This study is designed to be a 12-month double blinded randomized trial. Eligible patients will be randomized to control
or intervention group. Study participants in the “treatment” assignment group will receive 600 mg oral administration of lipoic acid
while control group will follow routine care alone (without lipoic acid).
Rationale:
Increased production of free radicals and depletion of antioxidants are commonly observed in diabetic patients. Based on animal
studies, increased production of free radicals tends to persist even after blood glucose is tightly controlled. The rationale of using a
potent antioxidant is based on the observation that increased oxidative stress associated with hyperglycemia can contribute to
cellular injury leading to apoptosis; consequently, leading to diabetic retinopathy. Evidence from animal model showed that alpha
lipoic acid (a potent antioxidant) was effective for decreasing the progression of diabetic retinopathy and in reducing free radicals.
However, there is no randomized study that has investigated the use of alpha lipoic acid in the management of diabetic
retinopathy. Human studies showing the beneficial effect of alpha lipoic acid has only been shown on diabetic patient with
neuropathy. It is important to note that exaggerated production of reactive oxygen species (ROS) is related to progression of nerve
dysfunction and is one of the primary causes of diabetic neuropathy.
Therefore, we hypothesize that therapy that can exert a powerful antioxidant activity can provide a therapeutic modality needed to
target the pathogenesis of diabetic retinopathy.
Significance of the Research:
In the United States alone, approximately 60% of those patients diagnosed with type 2 diabetes for 20 years have diabetic
retinopathy. Health care expenditures associated with diabetic retinopathy increases as the severity of the disease progresses. The
main stay of treatment of proliferative diabetic retinopathy is photocoagulation, the use of VEGF inhibitors, and tight glucose
control. Photocoagulation and VEGF inhibitors are expensive and invasive treatment modalities. This study will explore a less
expensive alternative to target free radicals, with the specific aim of exploring its efficacy in reducing the rate of progression of nonproliferative diabetic retinopathy to the potentially blinding proliferative type.
Primary Hypothesis:
1. Patients who receive oral administration of alpha lipoic acid 600 mg daily will experience decreased progression of retinopathy
compared to patient who did not. Decrease in progression of retinopathy has been demonstrated by measuring the levels of
inflammatory cytokines.
- The hypothesis stems from scientific evidence that certain cytokines such as M-CSF, interleukin 6 and 8 levels are elevated in
patients with diabetic retinopathy. Evidence of suppressed inflammatory cytokines will be an indication for decreased progression
of retinopathy.
2. Preservation of visual acuity and retinal thickness of patients, with moderate diabetic retinopathy, who received oral
administration of alpha lipoic acid 600 mg.
Secondary hypothesis:
1. Patients who receive oral administration of alpha lipoic acid 600 mg daily will have higher blood level of glutathione than those
who did not.
- The hypothesis stems from the evidence that elevated levels of glutathione is maintained in the presence of alpha lipoic acid.
Maintained elevated levels of glutathione will suggest the activity and efficacy of alpha lipoic acid.
Outcome Variables:
Primary Outcome Variables:
1. Decreased progression of diabetic retinopathy as measured and graded by using Standard ETDRS 7 –field color stereoscopic
funds photograph, and also by measuring the levels of interleukin 6, 8 and M-CSF using flow cytometer
2. Changes in retinal thickness and visual acuity as measured by Optical coherence tomography (OCT) and Electronic Visual Testing
algorithm respectively
Secondary Outcome Variable:
1. Changes in the plasma level of glutathione as measured by Tandem-Mass Spectrometer
