Brief Summary

Management of symptoms associated with diabetic neuropathy is a difficult issue for clinicians since it usually does not respond to standard analgesics. Resveratrol is a naturally occurring plant-derived, polyphenolic compound, it exerts pleiotropic activity. The investigators believed that the implementation of multidisciplinary approaches including pharmacotherapy and provision of healthcare professional services such as pharmacist intervention are needed for alleviation of diabetic associated neuropathy.Therefore, the hypothesis of the present protocol is that the administration of resveratrol and/or provision of pharmaceutical care in patients with diabetic neuropathy might be of value in improving quality of life and managing diabetic neuropathic pain.The study is designed as a four-arm randomized, placebo-controlled clinical trial. Group one will be given only conventional hypoglycemic drugs. Group two patients will receive conventional hypoglycemic drugs accompanied by pharmacist interventions. Group three; patients will receive resveratrol 500 mg orally once daily after meals for three months, in addition to their regular hypoglycemic drugs. Group four; patients will receive resveratrol 500 mg orally once daily after meals along with their regular hypoglycemic drugs for a period of three months, accompanied by pharmacist interventions. Neuropathic pain will be measured by various neuropathic pain assessment tools. Nerve conduction studies will be performed to assess the effect of interventional therapy. The expected outcome will be the improvement of diabetic neuropathy associated symptoms along with glycemic status.

Outcome Measures

Primary Outcomes (6)

  • visual analog scale (VAS)

    to assess neuropathic pain, VAS scale ranges between 0-10 , 0 indicates no pain while 10 indicates severe pain.

    up to 3 months

  • Douleur Neuropathique 4 questionnaire (DN4)

    to assess the severity of diabetic peripheral neuropathy.

    up to 3 months

  • The Michigan Neuropathy Screening Instrument (MNSI)

    to assess the severity of diabetic peripheral neuropathy

    up to 3 months

  • Electroneurography

    Motor nerve conduction velocity (m/s), sensory nerve conduction velocity(m/s) will be measured using surface electrodes.

    up to 3 months

  • Assessment of Quality of Life

    using the RAND-36 health survey questionnaire

    up to 3 months

  • Serum neopterin levels

    biochemical marker for peripheral neuropathy

    up to 3 months

Secondary Outcomes (3)

  • The mean change in fasting blood glucose

    up to 3 months

  • Mean change of glycated hemoglobin (HbA1c)-mmol/l

    up to 3 months

  • Measurement of serum level of LDL, cholesterol, HDL, Triglyceride

    up to 3 months

Eligibility Criteria

Age50 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with pain due to bilateral peripheral neuropathy caused by type 2 diabetes mellitus.
  • HbA1c of greater than 7%
  • The daily pain must be present for at least 6 months, and the diagnosis will be confirmed by a score \>4 on the Michigan Neuropathy Screening Instrument (MNSI), Douleur Neuropathique 4 (DN4). The severity of pain when evaluated for the past 24 was ≥4 on the 10 cm Visual Analogue Scale (VAS) at baseline without the use of analgesic for 48 hours.

You may not qualify if:

  • Older subjects with high risks of cardiovascular diseases,
  • Pregnant or breastfeeding,
  • Having a prior renal transplant or current renal dialysis,
  • Patients have a diagnosis of major depressive disorder, generalized anxiety disorder, heavy alcohol drinkers,
  • Significant hepatic or renal disease,
  • Patients on antioxidant therapy, or pentoxyphylline within the last month.
