Objective The causes of fever of unknown origin (FUO) vary depending on the region and time period. We herein present a study of patients with classic FUO where we investigated differences based on patient background factors, such as age and causative diseases, and changes that have occurred over time. Methods We extracted and analyzed data from the medical records of 256 patients ≥18 years old who met the criteria for classic FUO and were hospitalized between August, 1994 and December, 2012. Results The median age of the patients was 55 years (range: 18-94 years). The cause of FUO was infection in 27.7% of the patients (n=71), non-infectious inflammatory disease (NIID) in 18.4% (47), malignancy in 10.2% (26), other in 14.8% (38), and unknown in 28.9% (74). The most common single cause was human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (n=17). NIID and malignancy were more common in patients ≥65 years old than in patients <65 years old. During 2004-2012, compared to 1994-2003, infections and "other" causes were decreased, whereas NIID, malignancy, and unknown causes were increased. Conclusion FUO associated with HIV/AIDS is increasing in Japan. In addition, as in previous studies in Japan and overseas, our study showed that the number of patients in whom the cause of FUO remains unknown is increasing and exceeds 20% of all cases. The present study identified diseases that should be considered in the differential diagnosis of FUO, providing useful information for the future diagnosis and treatment of FUO.

Aim: The aim was to investigate the respective associations between lifestyle and proteinuria and the estimated glomerular filtration rate (eGFR).Methods: The lifestyle habits of 25,493 middle-aged participants were investigated in a cross-sectional study to find habits that are associated with a low eGFR (<60 mL/min/1.73 m2) and/or the presence of proteinuria. The lifestyle habits of the participants were evaluated using a questionnaire. Unhealthy lifestyle habits were defined as follows: 1. obesity, 2. being a current/former smoker, 3. eating irregular meals, 4. having less than 5 hours sleep, 5. exercising less than once a week, and 6. drinking more than once a week. The associations among unhealthy habits, eGFR, and proteinuria were evaluated using multivariate analysis.Results: The following lifestyle factors were significantly and independently associated with proteinuria: obesity (odds ratio (OR): 1.18, 95%C.I: 1.04-1.34), being a current/former smoker (OR: 1.26, 95%C.I: 1.11-1.42), eating irregular meals (OR: 1.40, 95%C.I: 1.22-1.61), sleeping less than 5 hours (OR: 1.38, 95%C.I: 1.15-1.65), and exercising less than once a week (OR: 1.18, 95%C.I: 1.05-1.33). In contrast, the following unhealthy lifestyle factors were not clearly associated with a low eGFR: obesity (OR: 1.05, 95%C.I: 0.95-1.17), being a current/former smoker (OR: 0.76, 95%C.I: 0.69-0.84), eating irregular meals (OR: 0.91, 95%C.I: 0.79-1.04), sleeping less than 5 hours (OR: 1.02, 95%C.I: 0.85-1.22), and exercising less than once a week (OR: 0.91, 95%C.I: 0.83-0.99).Conclusion: Associations between proteinuria and unhealthy lifestyle habits were observed in our cross-sectional study. Unhealthy lifestyles should be monitored during the management of CKD patients with proteinuria.

Objective The aim of this study was to investigate the associations between the incidence of diabetes and the accumulation of markers of impaired glucose metabolism; i.e., pre-diabetes. Methods This retrospective cohort study recruited 1,631 men without diabetes at baseline who attended more than two routine health check-ups at our institution between 2006 and 2012. The participants were divided into four groups based on the number of markers of impaired glucose metabolism exhibited at the initial examination. The following markers of impaired glucose metabolism were defined as risk factors for diabetes: a fasting plasma glucose level of ≥110 mg/dL, 2-hour plasma glucose level of ≥140 mg/dL and glycated hemoglobin (HbA1c) value of ≥6.0% (42 mmol/moL). The risk of developing diabetes was assessed using a multivariate analysis. Results The median examination interval was 1,092 days. The incidence of diabetes rose in association with the number of markers. The subjects with two markers displayed a multivariate-adjusted odds ratio (OR) for diabetes of 19.43 [95% confidence interval (CI): 9.70-38.97] and the subjects with three markers displayed an OR of 48.30 (95% CI: 20.39-115.85) compared with the subjects with one or no markers. Conclusion The present results demonstrate the impact of accumulating markers of impaired glucose metabolism on the risk of developing diabetes. Anti-diabetes intervention strategies should aim to comprehensively assess an individual's risk of developing diabetes at the pre-diabetes stage.
