A 40-year-old female visited our hospital because of malaise. She had no history of early loss of primary teeth nor family history of skeletal dysplasia. Laboratory examination showed low serum alkaline phosphatase levels of 18 U/L. In addition, hypozincemia was also observed, but alkaline phosphatase level did not increase after zinc replacement. Mediators, including calcium and phosphorus metabolism, were within normal range. X-ray examination showed no evidence of osteomalacia, but mineral bone density was slightly decreased compared with the young adult mean. Urine phosphoethanolamine level was increased, and we then suspected hypophosphatasia. Genetic tests detected ALPL gene heterozygous missense mutation (c.529G>A p.Ala177Thr and c.670A>G p.Lys224Glu) and adult-onset hypophosphatasia was finally diagnosed. It is important to evaluate alkaline phosphatase levels in the screening of patients with non-specific symptoms.

The effect of white rice (WR) mixed with high β-glucan-containing barley at 50% on improvement of postprandial blood glucose levels was assessed by meal tolerance test and continuous glucose monitoring (CGM) in 15 healthy subjects with normal glucose tolerance (age 31.6 ± 12.9 years old, 4 males and 11 females). A meal tolerance test (500 kcal) was conducted using 2 types of test meals: a test meal only with WR and a test meal WR mixed 50% barley, and the side dish was the same in both meals. Blood glucose levels of the subjects 180 minutes after ingestion of the test meals were compared. In addition, a CGM device was attached to the subjects for 2 days when the WR or barley as a staple food was provided 3 times a day for consecutive days, and the daily variation of glucose was investigated. The glucose levels 30 minutes after dietary loads and the area under the blood concentration-time curve over 180 minutes were significantly decreased in the barley consumption group. In CGM, 24-hour mean blood glucose and 24-hour standard deviation of blood glucose were also significantly decreased after ingestion of the barley. Postprandial glucose level elevation was suppressed by mixing high-β-glucan barley with WR in subjects with normal glucose tolerance.
