Aim: Epidemiological evidence regarding the relationship between fish and fatty acid intake and carotid intima-media thickness (CIMT) has been limited and inconsistent. The current cross-sectional study investigated this issue using baseline data from the Aidai Cohort Study. Methods: Study subjects were 2024 Japanese men and women aged 34-88 years. Right and left CIMT were measured at the common carotid artery using an automated carotid ultrasonography device. Maximum CIMT was defined as the largest CIMT value in either the left or right common carotid artery. Carotid wall thickening was defined as a maximum CIMT value >1.0 mm. Results: The prevalence of carotid wall thickening was 13.0%. In men, intake of n-3 polyunsaturated fatty acids (PUFA) was independently positively related to the prevalence of carotid wall thickening, while no associations were found between intake of fish and the other fatty acids and carotid wall thickening or maximum CIMT. In women, intake levels of fish, n-3 PUFA, eicosapentaenoic acid, docosahexaenoic acid, and arachidonic acid were independently inversely associated with carotid wall thickening and intake levels of fish, n-3 PUFA, α-linolenic acid, n-6 PUFA, and linoleic acid were independently inversely associated with the maximum CIMT. No significant relationships were found between intake of total fat, saturated fatty acids, or monounsaturated fatty acids and carotid wall thickening or maximum CIMT regardless of sex. Conclusions: In women, higher intake of fish and n-3 and n-6 PUFA may be associated with a lower prevalence of carotid wall thickening and a decrease in maximum CIMT.

Dipeptidyl peptidase-4 (DPP-4) inhibitors are a newer class of oral hypoglycemic agents for the management of diabetes that elevate the plasma concentration of active glucagon-like peptide-1 via inhibition of DPP-4. They effectively lower not only glycosylated hemoglobin levels, but also fasting and postprandial plasma glucose levels. Patients with diabetes occasionally consume an overdose of oral hypoglycemic agents in suicide attempts: the prevalence of depression is high in patients with diabetes, and depression is a strong risk factor for suicide. We encountered an 86-year-old woman with type 2 diabetes and depression, who was transferred to the emergency room 4h after ingestion of 1,700 mg of the DPP-4 inhibitor sitagliptin (1,700 mg is 17 times greater than the approved maximum dose). Upon arrival, she was fully conscious, plasma glucose was 124 mg/dl, and serum immunoreactive insulin level was 5.81 μU/ml. Thereafter, the plasma concentration of sitagliptin rose to 3,793 nM, which is 4.5 times higher than the value found under regular treatment with the maximum dose. The patient did not suffer from hypoglycemia, suggesting that a single oral overdose of sitagliptin is unlikely to cause hypoglycemia. A literature review of oral anti-diabetic agents revealed that overdose of biguanides is occasionally fatal when immediate intensive care is not provided. In summary, sitagliptin is a good treatment option for diabetic elderly patients or patients with psychiatric disorders who are suicidal and do not require insulin.

Subclinical hypothyroidism (SCH) has been associated with type 2 diabetes mellitus. However, it is unknown whether common complications of type 2 diabetes, such as diabetic nephropathy, are also present with SCH. Here, we investigated the association between SCH and diabetic nephropathy among Japanese patients with type 2 diabetes mellitus. In this multicenter cross-sectional study, we recruited 414 such patients who had no previous history of thyroid disease. Serum thyroid hormone levels and the urinary albumin:creatinine ratio were measured. SCH was defined as an elevated thyroid-stimulating hormone (TSH) level (>4.0 mIU/L), and diabetic nephropathy was defined as creatinine levels ≥300 mg/g. The prevalence of SCH was 8.7% (n = 36) among patients with type 2 diabetes mellitus. The SCH group had a higher prevalence of dyslipidemia (p = 0.008) and diabetic nephropathy (p = 0.014) than the euthyroid group. Multivariate analysis identified significant positive associations between diabetic nephropathy and SCH (odds ratio [OR], 3.51; 95% confidence interval [CI], 1.10-10.0; p = 0.034), hypertension (OR, 4.56; 95% CI, 1.69-14.7; p = 0.001), and smoking (OR, 3.02; 95% CI, 1.14-7.91; p = 0.026). SCH may be independently associated with diabetic nephropathy in Japanese patients with type 2 diabetes mellitus.
