Objective While an association between a reduced kidney function and hyperuricemia has been reported, its association with hypouricemia is not well understood. The present study therefore investigated this association. Methods Using a large Japanese health examination dataset, we performed a multivariable logistic regression analysis to assess the association between serum uric acid (SUA) levels and a reduced kidney function. ⋯ Compared with the 2nd group, the other 4 groups groups had a significantly higher prevalence of a reduced kidney function [odds ratio (OR), 2.58; 95% confidence interval (CI), 1.64-4.06 in men; OR, 1.66; 95% CI, 1.16-2.39 in women]. Conclusion The prevalence of a reduced kidney function was high in both men and women in the hypouricemia and high-SUA groups. SUA levels and the prevalence of a reduced kidney function showed a J-shaped association.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder that causes abnormal blood vessel formation and bleeding. We herein report a 61-year-old woman with aggravated HHT symptoms after hemodialysis initiation. ⋯ Eventually, the patient died of extensive cerebral hemorrhaging. Our experience suggests that special attention should be paid to bleeding complications in high-risk patients.

Objectives Fabry disease is characterized by the systemic accumulation of globotriaosylceramide (Gb3) and globotriaosylsphingosine (Lyso-Gb3), which are widely used as biomarkers of the disease. However, few reports have described the relationship of Lyso-Gb3 analogs and Gb3 isoforms with the disease. The present study determined the profiles of Lyso-Gb3 analogs and Gb3 isoforms accumulated in body fluids from various phenotypic Fabry patients to elucidate the basis of the disease. ⋯ However, minor differences in the ratio of each Lyso-Gb3 analog and Gb3 isoform with respect to the total Lyso-Gb3 analogs and Gb3 isoforms, respectively, were observed among individual classic Fabry men. Their time courses were well associated with the development and attenuation of anti-drug antibodies in a patient with classic Fabry disease during ERT. Conclusion Quantification of Lyso-Gb3 analogs and Gb3 isoforms provides us with more detailed information about the substrates that accumulated in the body fluids of Fabry patients than does quantification of Lyso-Gb3 and Gb3 alone, so this approach may be useful for elucidating the basis of Fabry disease.

Zinc Administration Favorably Affects Prophylactic Therapy-refractory Migraine Attacks: A Case Series.
Notably, certain nutrients are effective in preventing migraine. Nonetheless, zinc replacement therapy for migraine treatment has yet to be explored. ⋯ Zinc administration may be an option for treating patients with prophylaxis-refractory migraine. Further investigation is required to determine the efficacy of zinc replacement therapy as a treatment option for migraine.
