About this trial

This is an interventional treatment trial for Type 2 Diabetes (Adult Onset) focused on measuring diabetes mellitus, diabetic neuropathy, hyperglycemia

Eligibility Criteria

25 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients with a diagnosis of type 2 diabetes mellitus (T2DM).
  • HbA1c at baseline: ≥7.5 % to 8.5 %.
  • BMI between ≥26 and ≤35 kg/ m2.
  • Established Diabetic neuropathy diagnosed by nerve conduction study (NCS).

Exclusion Criteria:

  • Patients diagnosed with type 1 diabetes mellitus or diabetes secondary to pancreatitis or resection of the pancreas.
  • Patients diagnosed with hemoglobinopathies, hemolytic anemia, or other diseases which interfere with HbA1c measurement.
  • Thyroid disease, cardiovascular disease, peripheral vascular disease, coagulopathy, moderate to severe liver disease (bilirubin>1.5mg), or renal excretion ≤90ml/min.
  • Patients on medications which can result in a change of weight (orlistat, metformin, clozapine, gabapentin) and patients on medications that can interfere with glucose or lipid metabolism (corticosteroids, non-selective β-blockers, thiazides, etc.)
  • Treatment with any diabetes medications other than glimepiride prior to intervention.
  • Clinically significant cardiac abnormalities (diagnosed clinically, history, or by X-ray/ECG) that were not related to type 2 diabetes mellitus and that required further evaluation.
  • Patients with morbid obesity (BMI ≥ 40 kg/ m2).
  • History or current diagnosis of major depressive disorders or other psychiatric disorders.
  • Pregnant and breastfeeding women.
  • Patients with any inflammatory diseases.
  • Patients on cytochrome P450 inducers (e.g., rifampicin, phenobarbital, carbamazepine, phenytoin, etc.).
  • Patients with Low vitamin B12 levels according to suggested normal values for T2DM patients over 60 years old (<400 pmol/L).

Arms of the Study

Arm 1

Arm 2

Arm Type

Active Comparator

Experimental

Arm Label

Alpha-lipoic acid arm

Roflumilast arm

Arm Description

Administration of alpha-lipoic acid 600 mg orally once daily for 3 months.

Administration of roflumilast 500 mcg orally once daily for 3 months.

Outcomes

Primary Outcome Measures

Change in fasting blood glucose
Using glucose oxidase method for assessment of blood glucose and subtracting pre-treatment from post-treatment values
Change in plasma insulin level
Subtracting pre-treatment from post-treatment values of plasma insulin
Change in HOMA-IR index
HOMA-IR will be calculated for all patients at baseline and 3 months later.
Change in HOMA-B index
HOMA-B will be calculated for all patients at baseline and 3 months later.
Change in HbA1c
Subtracting pre-treatment from post-treatment values of HbA1C

Secondary Outcome Measures

Changes in TNF-alfa serum level
Subtracting pre-treatment from post-treatment values of TNF-alfa.
Changes in malondialdehyde serum level (MDA)
Subtracting pre-treatment from post-treatment values of MDA.
Changes in neurotensin serum levels
Subtracting pre-treatment from post-treatment values of neurotensin serum levels.
Ewing score
Subtracting pre-treatment from post-treatment changes in summation of the cardiac autonomic reflex tests (CARTs) including heart response to a deep breathing test, changes in immediate heart rate response to standing, and changes in blood pressure response to sustained handgrip testing.
Changes of Michigan Neuropathy Screening Instrument
A 15-item questionnaire (MNSIQ) is used to assess deformation, infection, skin thickening of the skin's stratum corneum, and ulcers. MNSIQ was designed to screen for diabetic neuropathy through questionnaires on 15 questions that are related to neuropathic symptoms (pain, temperature, and sensation). Two of 15 (number 4 and 10) are vascular symptoms and are excluded from the total score regardless of the results. If you answered 'No' to questions 7 and 13, you will get 1 point. In the end, scores ranging from 0 to 13 indicate that the higher the score, the more severe the neuropathic symptoms.
Changes of Michigan Neuropathy Screening Instrument(MNSIE)
A foot test (MNSIE) is used to assess deformation, infection, skin thickening of the skin's stratum corneum, and ulcers. MNSIE evaluates foot shape, foot ulceration, ankle reflex, sense of vibration of big toe, monofilament right and left. The score ranges from point 0 to 10, and when the score is above 2, it is diagnosed as neuropathy.
Changes of Douleur Neuropathique-4 (DN4) questionnaire (DN4)
DN4 Neuropathic Pain Diagnostic Questionnaire which reflect positive symptoms for pain ( burning, painful cold, electric shocks, )
