Abstract

Objectives: To determine the frequency of sensory motor neuropathy in type 2 diabetics at the time of presentation to the hospital.

Study design: Non interventional, descriptive.

Subjects and methods: The study was conducted at Medical Unit-1, Jinnah Postgraduate Medical Center, Karachi, from November 2005 to April 2006. Patients of different ages and either gender with history of confirmed diabetes for ten years and above, on regular follow up were included. Those with non-diabetic causes of hyperglycemia or neuropathy were excluded. Relevant features like age, gender, treatment, symptoms , signs, nerve conduction study (NCS) results, duration of Diabetes mellitus (DM), fasting blood sugar (FBS) and serum values of glycosylated hemoglobin (HB1Ac) were  recorded. Results: Out of a total of 300 patients, there were 111 female and 189 male patients. Mean age was 58 11.23 years. Mean duration of diabetes was 13.6 5.48 years. One hundred and twenty three patients had symptoms of neuropathy. Clinical examination revealed mixed sensory and motor signs in 135 (45%) patients. Nerve conduction studies revealed abnormalities in 159 (53%) patients. Among patients having an abnormal NCS, the fasting blood glucose (FBS) was <120 mg/dl in 12 (7.5%) patients, while it was > 120mg/dl in 147 (91%) patients. The glycosylated hemoglobin ranged from 4-15% with mean of 8.1% and standard deviation of 2.5%. This showed significant association (p <0.001) of peripheral neuropathy with abnormal FBS, HB1Ac and duration of diabetes.

Conclusion:  NCS diagnosed the neuropathy in more than half of the total number of patients, including both symptomatic and asymptomatic patients. Majority of the patients revealed symmetrical and a mixed type (motor and sensory) polyneuropathy.  This shows that nerve conduction may not be concordant with the clinical signs and symptoms. NCS detects neuropathy much earlier, before it becomes evident clinically. The neuropathy is associated with abonromal fasting blood sugar, HBIAC and duration of diabetes.
