In a previous study, we observed that the Results of an organized questionnaire to assess the presence of diabetic neuropathy (Diabetic Neuropathy Symptoms-DNS) were associated with the presence of scores of depressive symptoms (BDI ≥10).
To evaluate how different scores for the presence of symptoms/signs of neuropathy (Neuropathy Diabetes Score-NDS; Neuropathy Symptoms Score-NSS; DNS and esthesiometry) had sensitivity and specificity, compared to the gold standard score of Michigan (MNSI) (≥2,5) and the gold standard score of Beck depressive symptoms (BDI).
Materials and methods
207 patients with Diabetes type 2 were evaluated with MNSI, BDI, NDS, esthesiometry, NSS and DNS.
Questionnaires used to define the presence of polyneuropathy have a similar sensitivity for the detection of symptoms of depression (70 to 80%), while the physical examination for the presence of polyneuropathy (NDS) and esthesiometry has a sensitivity of ±50% and specificity of ±85% compared to MNSI and a sensitivity of ±23% and specificity of ±85% when compared to BDI (Figure 1). The symptom questionnaires have sensitivity and specificity of±75% and±35%, respectively, for both MNSI and BDI.
We suggest not to use only questionnaires to define the presence of neuropathy in diabetic patients-in daily practice, physical examination (MNSI or NDS) must be used.
