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.

Objective We attempted to elucidate the clinical features of chronic hepatitis C patients who develop hepatocellular carcinoma (HCC) after achieving a sustained viral response (SVR) to interferon (IFN) therapy. Methods The clinical features of 130 patients at 19 hospitals who developed HCC after obtaining an SVR were retrospectively reviewed. Results Overall, 107 (82%) of the 130 patients were men, with 92 (71%) being ≥60 years of age and 76, 38 and 16 developing HCC within 5, 5-10 and 10-16.9 years after IFN therapy, respectively. Before receiving IFN therapy, 92 (71%) patients had cirrhosis and/or a low platelet count (<15×104 cells/μL). Lower albumin (<3.9 g/dL) and higher alpha fetoprotein (AFP) (≥10 ng/mL) levels were identified in a multivariate analysis to be independent variables of the development of HCC within five years after IFN therapy. Among 4,542 SVR patients, HCC occurred in 109 (2.4%) during a 5.5-year follow-up period, thus resulting in an occurrence rate of 4.6% for men and 0.6% for women. Conclusion SVR patients with lower albumin or higher AFP levels require careful assessments to prevent early HCC development after IFN therapy. HCC occurrence within >10 years of IFN therapy is not uncommon, and the risk factors remain uncertain, thus suggesting that all SVR patients should undergo long-term follow-up examinations for HCC development.
