Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. Many factors such as diabetes mellitus, hypothyroidism, hormonal replacement therapy, corticosteroid use, rheumatoid arthritis and wrist fractures may cause CTS. Metabolic syndrome includes abdominal obesity, dyslipidemia, hyperglycemia, and hypertension that may cause CTS. In this study, we aimed to evaluate the relation between CTS and metabolic syndrome. We studied 107 (96 female and 11 male) right-handed patients who had a clinical and electrophysiologically confirmed diagnosis of CTS. We then divided the patients into two groups (patients with and without metabolic syndrome) according to the criteria of ATP III definition. Eighty (75%) of the patients with CTS had metabolic syndrome. Among the 80 patients with metabolic syndrome, CTS was found in 150 hands (43 mild, 58 moderate and 49 severe cases). Among the 27 patients without metabolic syndrome, CTS was found in 43 hands (27 mild, 14 moderate and 2 severe cases). The electrophysiological parameters (median nerve distal motor latency, median nerve motor amplitude, median nerve motor conduction velocity, median nerve sensory onset latency, median nerve sensory amplitude and median nerve sensory conduction velocity) were worse in patients with metabolic syndrome (P < 0.05). In conclusion, metabolic syndrome was found to be three times more common in patients with CTS and CTS was more severe in patients with metabolic syndrome when compared with those without metabolic syndrome.

Insulin resistance syndrome is characterized by hyperglycemia, atherogenic dyslipidemia, hypertension, and abdominal obesity. Hyperglycemia is the major risk factor for microvascular complications in type 2 diabetes. However, 70% to 80% of patients with type 2 diabetes will die of macrovascular disease. Atherogenic dyslipidemia-characterized by elevated triglyceride levels, low high-density lipoprotein cholesterol (HDL-c) levels, and a preponderance of small, dense, low-density lipoprotein (LDL) particles-is the major cause of atherosclerosis in individuals with type 2 diabetes. Therefore, treatment of type 2 diabetes must address hyperglycemia to prevent microvascular disease (retinopathy, neuropathy, and nephropathy) and atherogenic dyslipidemia to prevent macrovascular complications. Emerging evidence indicates lipid and glucose homeostasis are interrelated via bile acid-activated nuclear hormone receptor signaling pathways. Agents that act on these pathways could simultaneously address hyperglycemia and dyslipidemia in patients with type 2 diabetes. Recent studies have shown that bile acid sequestrants, including cholestyramine, colestimide, and colesevelam HCl, significantly improve glycemic control and reduce LDL cholesterol levels in patients with type 2 diabetes. This paper will review the effects of bile acid sequestrants on both glucose and lipid metabolism in patients with type 2 diabetes.

The lowest glycemic threshold for and the risk factors associated with neuropathic pain have not been established. The aim of this study was to determine the prevalence and risk factors of neuropathic pain in survivors of myocardial infarction with diabetes, impaired glucose tolerance (IGT), impaired fasting glucose (IFG), normal glucose tolerance (NGT). Subjects aged 25-74 years with diabetes (n=214) and controls matched for age and sex (n=212) from the population-based KORA (Cooperative Health Research in the Region of Augsburg) Myocardial Infarction Registry were assessed for neuropathic pain by the Michigan Neuropathy Screening Instrument using its pain-relevant questions and an examination score cutpoint >2. An oral glucose tolerance test was performed in the controls. Among the controls, 61 (28.8%) had IGT (either isolated or combined with IFG), 70 (33.0%) had isolated IFG, and 81 had NGT. The prevalence of neuropathic pain was 21.0% in the diabetic subjects, 14.8% in those with IGT, 5.7% in those with IFG, and 3.7% in those with NGT (overall p<0.001). In the entire population studied (n=426), age, waist circumference, peripheral arterial disease (PAD), and diabetes were independent factors significantly associated with neuropathic pain, while in the diabetic group it was waist circumference, physical activity, and PAD (all p<0.05). In conclusion, the prevalence of neuropathic pain is relatively high among survivors of myocardial infarction with diabetes and IGT compared to those with isolated IFG and NGT. Associated cardiovascular risk factors including abdominal obesity and low physical activity may constitute targets to prevent neuropathic pain in this population.

Chronic pain is more common in the elderly and impairs functioning and quality of life. Though obesity, defined by body mass index (BMI), has been associated with pain prevalence among older adults, the mechanism of this association remains unclear. We examined components of the metabolic syndrome, insulin resistance, a marker of inflammation, and the presence of painful comorbidities as possible mediators of this association. Participants were 407 individuals aged >70 in the Einstein Aging Study. Chronic pain and pain over the last 3 months were defined using the Total Pain Index (TPI). Insulin resistance was modeled as fasting insulin, HOMA and QUICKI. High sensitivity C-reactive protein was used as a marker of inflammation. Cross-sectional logistic regression models were constructed to assess the associations of these factors with prevalent pain, adjusted for other known pain correlates. Prevalence of chronic pain was 52%. Of the clinical components of metabolic syndrome, central obesity was significantly associated with pain (OR 2.03, 95% CI 1.36-3.01). After adjustment for insulin resistance, inflammation, and pain-related comorbidities, central obesity predicted higher TPI scores (OR 1.55, 95% CI 1.04-2.33) and nearly doubled the risk of chronic pain (OR 1.70, 95% CI 1.05-2.75). Central obesity is the metabolic syndrome component showing the strongest independent association with pain, and the relationship is not explained by markers of insulin resistance or inflammation, nor by the presence of osteoarthritis or neuropathy.

Meralgia paresthetica is a compression neuropathy of the lateral femoral cutaneous nerve. Despite its rarity, it is the most common nerve entrapment of the lower limbs. It produces similar symptoms as those associated with the more common L4 or L5 radiculopathy. Therefore, it is often diagnosed late (sometimes only after several years of latency) or not at all. This diagnosis should be considered especially in patients with obesity and diabetes who have chronic irritation of the ventrolateral areas of the thigh not responding to conservative therapy and a negative finding on lumbar MRI. We present our experience with surgical nerve decompression in three patients with pain, paresthesias, and sensory loss within the distribution of the lateral cutaneous nerve of the thigh. They all suffered from severe abdominal obesity. All conservative treatments, including weight reduction attempts, were unsuccessful. Nerve release caused an immediate effect in two cases. One patient experienced a temporary worsening of pain, which gradually improved within one month. In spite of the controversy surrounding the surgical treatment of meralgia (neurolysis or nerve resection), it can be concluded that nerve decompression has a good effect. Nerve resection is, in our view, considered to be a reserve option when primary surgery fails. Key words: meralgia paresthetica - nerve entrapment - peripheral nerve.
