Painful Diabetic Neuropathy Clinical Trial
Official title:
The Benefits of Astaxanthin as Add on Therapy in the Management of Painful Diabetic Neuropathy Patient: Randomized Clinical Trial
Diabetes is one of the main health care problemsworldwide with 5% average increased number of cases every year. According to International Diabetes Federation the prevalence of people with diabetes reached the number of 425 million people in 2017 and estimated rising to 628 million by 2045. Painful Diabetic Neuropathy (PDN) is the most common complication of diabetes affecting 90% of the patients. The symptoms of PDN include numbness, burning, stabbing pain, paraesthesia or hyperesthesiaof both symmetrical limbthat could reduce the quality of life. Several studies have found several therapeutic options to cope with pain in the PDN, but the results are not as satisfactory due to the uncertain pathophysiology of the disease and the limitations of the drug that can be administered because of itspolypharmaceutical side effects. The causes of diabetic neuropathy not only include vascular and metabolic factors but also Reactive Oxygen Species. There are several therapeutic options that can be administered such as glycemic index arrangement,foot care, symptomatic treatment, and predominantly pain therapy. According to guidelines, there are drugs therapy thatrecommended for PDN, among others, Gabapentin, Pregabalin and anticonvulsants until the pain subsides. Unfortunately, this treatment is only aimed at relieving the symptoms of existing pain but not working on existing pathophysiological mechanisms and fixing sensory deficits of neuropathy trials. Multi-target treatments is needed to attenuate neuronal inflammation, oxidative stress and apoptosis. Additional therapy can be an option to support healing and also the process of metabolic pathophysiology that occurs due to rising glycemic index in the body that causes the work of hexosamine pathway and trigger the formation of ROS and inflammation. There is evidence of research demonstrating the neuroprotective effects of Astaxanthin as oxidative, anti-inflammatory and anti-apoptotic agent. Not only that, Astaxanthin is also a good supplement addition with no toxic effects when consumed, as well as hydrophilic and also lipophilic nature which makes Astaxanthin can penetrate the BBB effectively.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Improvement in Visual Analogue Scale (VAS) at week 4 | Change in pain impact on daily life as measured by Visual Analogue Scale (VAS) from its baseline value. Visual analogue scale is a continuous scale comprised of a horizontal or vertical line, usually 10 centimeters (100 mm) in length, anchored by 2 verbal descriptors, one for each symptom extreme. The scale is most commonly anchored by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 100). The respondent is asked to place a line perpendicular to the VAS line at the point that represents their pain intensity. Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. | 4 weeks after treatment initiation | |
Primary | Improvement in Visual Analogue Scale (VAS) at week 8 | Change in pain impact on daily life as measured by Visual Analogue Scale (VAS) from its baseline and week 4 value. Visual analogue scale is a continuous scale comprised of a horizontal or vertical line, usually 10 centimeters (100 mm) in length, anchored by 2 verbal descriptors, one for each symptom extreme. The scale is most commonly anchored by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 100).

Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. | 8 weeks after treatment initiation | |
Primary | Improvement in Numeric Pain Scale at week 4 | Change in pain impact on daily life as measured by Numeric Pain Scale from its baseline value. Numeric pain scale is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. Higher scores indicating greater pain intensity. | 4 weeks after treatment initiation | |

Primary | Improvement in Brief Pain inventory at week 4 | Change in pain impact on daily life as measured by Brief Pain Inventory from its baseline value. The Brief Pain Inventory evaluates a patient's pain experience through a number of different scales. There are line drawings of the front and back of a human body on which patients mark the location of their pain. Patients are asked to list the treatments or medications that they are using and how much relief they have provided in the past 24 hours. In addition, patients fill out 11 different numeric rating scale that ask about pain intensity (ranging from 0 to 10) and the effect of the pain on their ability to function during various activities of daily living. A higher score indicates greater pain intensity. | 4 weeks after treatment initiation | |
