Background: Type 2 diabetic patients have a higher prevalence of thyroid disorders, particularly hypothyroidism.  Peripheral neuropathy is a common and disabling complication of diabetes mellitus. Peripheral nervous system involvement in hypothyroidism is also a well-documented fact. Nerve conduction studies are generally considered to be the most sensitive and reproducible in the assessment of peripheral neuropathies. This study helped to determine the prevalence of peripheral neuropathy in diabetic hypothyroid patients as well as to compare it in diabetic patients with or without hypothyroidism. It compared the onset latency, amplitude, conduction velocity and F- wave latency of some nerves in type 2 diabetes mellitus patients with or without hypothyroidism.Methods: With RMS, EMG, EP MARK-II, nerve conduction studies are done in 30 cases (type 2 diabetes mellitus patients with hypothyroidism) and 30 controls (type 2 diabetes mellitus patients of diabetes without hypothyroidism) respectively, attending the Diabetic Clinic and Biochemistry Laboratory of North Bengal Medical College.Results: Data were treated with Unpaired t-Test. The study reveals that type 2 diabetes mellitus patients with hypothyroidism have higher prevalence of peripheral neuropathy. There is statistically significant (p<0.00) decrease in motor nerve conduction study in both right and left median nerves in diabetic patients with hypothyroidism than in diabetic patients without hypothyroidism.Conclusions: All diabetic patients should be screened for early detection of hypothyroidism as type 2 diabetic patients with hypothyroidism have higher prevalence of peripheral neuropathy. The nerve conduction study remains the most reliable, accurate, and sensitive method to evaluate peripheral nerve function.

This cross-sectional study is aimed at determining the prevalence of distal symmetrical polyneuropathy (DSPN) and diabetic peripheral neuropathic pain (DPNP) in participants with type 2 diabetes mellitus (T2DM); finding the risk factors for DSPN and DPNP via biochemical tests; and correlating DSPN and DPNP with the results of electrophysiologic studies, quantitative sensory tests, and neurologic examination. The 145 participants with T2DM enrolled were divided into the DSPN (abnormal nerve conduction studies (NCS) with signs of polyneuropathy), subclinical DSPN (abnormal NCS without signs of polyneuropathy), minimal DSPN (normal NCS with signs of polyneuropathy), and no DSPN groups. The biochemical risk factors of diabetic peripheral neuropathy were investigated. Neurologic examinations, laboratory tests, NCS, vibration threshold tests, and thermal threshold tests were conducted. The modified Michigan Neuropathy Screening Instrument (mMNSI) and Douleur Neuropathique 4 were used to evaluate the severity of DSPN and DPNP, respectively. In all, 30% of participants had DSPN and 11% had DPNP. DSPN correlated strongly with male gender and higher glycohaemoglobin levels; NCS abnormality correlated with higher glycohaemoglobin levels; DSPN severity correlated with NCS of each stimulating nerve. DPNP commonly occurred with clinical and electrophysiologic evidence of DSPN. Symptomatic diabetic polyneuropathy significantly correlated with longer disease duration, higher glycohaemoglobin levels, and abnormal vibration tests. The thermal threshold test combined with nerve conduction tests could detect most of the patients with DSPN, subclinical DSPN, and minimal DSPN. Poor diabetic control was independently associated with the development of DSPN. DPNP was associated with DSPN. The combination of thermal threshold tests with NCS can potentially provide the diagnosis of DSPN.

Peripheral neuropathy is a common disabling complication in patients with diabetes and this complication is related to the duration of the disease process. Nerve conduction study is widely used for the assessment of diabetic polyneuropathy not only to evaluate the degree of abnormality but also to document serial changes in the clinical course of the disease. This study was designed to characterize motor nerve conduction abnormalities in subjects having relatively shorter and longer duration of type 2 diabetes mellitus and also to assess whether time related variable like duration of diabetes has any influence on motor nerve function of the subjects. Forty-four type 2 diabetic subjects were included in two groups:- Group B consisted of 23 diabetic subjects having duration of diabetes for 5-10 years (shorter duration) and Group C consisted of 21 diabetic subjects having duration of diabetes for 10-15 years (longer duration). Twenty-five age and BMI matched healthy subjects without family history of diabetes were included as Group A (non-diabetic) subjects. Motor nerve conduction velocities, action potential amplitudes and latencies of ulnar and peroneal nerves were measured by standard Nerve Conduction Velocity- Electromyography (NCV-EMG) equipment. Motor conduction parameters like ulnar compound muscle action potential (U CMAP), peroneal compound muscle action potential (P CMAP) and peroneal  nerve conduction velocity (P NCV) were found to be significantly reduced (p<0.001, <0.01, <0.01 respectively) in diabetic group with shorter duration of diabetes(Group B) in comparison to non-diabetic control group (Group A). In the diabetic group with relatively longer duration of diabetes (Group C) motor nerve conduction parameters like U CMAP and P NCV were significantly reduced (p<0.001, <0.01 respectively). The results showed that in the type 2 diabetic population, motor nerve conduction parameters were affected early and there was gradual deterioration of motor function as duration of diabetes increased. Though previous studies on diabetic neuropathy suggest that abnormalities of sensory nerve conduction are early features of diabetic nerve damage and sensory nerves are more susceptible to fall prey to metabolic assaults, the present study indicates that motor nerves are also involved and the neuropathic changes assessed by electro diagnostic methods in motor nerves may occur early in patients with type 2 diabetes mellitus. So, there may be some genetic and biochemical basis (other than hyperglycaemia) for early motor involvement in type 2 diabetic population of Bangladesh.
