Deterioration of Phosphate Homeostasis Is a Trigger for Cardiac Afterload　- Clinical Importance of Fibroblast Growth Factor 23 for Accelerated Aging.

Background: After the discovery of the Klotho gene, phosphate came into focus as a pathogenetic aging agent. Phosphate homeostasis is controlled by phosphate-regulating hormones: fibroblast growth factor 23 (FGF23), vitamin D3, and parathyroid hormone. This study investigated the relationship between the deterioration in phosphate homeostasis and arterial stiffness by measuring serum FGF23 concentrations. Methods and Results: The study subjects comprised 82 hospitalized patients (31 males, 51 females; mean [±SD] age 78.6±10.5 years). All patients underwent chest computed tomography, measurement of central blood pressure (BP), and blood chemistry tests. Arterial calcification and/or stiffness was evaluated using the Agatston calcification score (ACS) and pulse wave velocity (PWV). PWV was significantly correlated with age (t=23.47, P<0.0001), estimated glomerular filtration rate (eGFR; t=-4.40, P<0.0001), and ACS (t=4.36, P<0.0001). Serum FGF23 concentrations were significantly correlated with age (t=2.52, P=0.014), eGFR (t=-3.37, P<0.001), serum inorganic phosphorus concentrations (t=3.49, P<0.001), serum vitamin D3 concentrations (t=-4.57, P<0.001), ACS (t=2.30, P=0.025), augmentation pressure (t=2.48, P=0.015), central systolic BP (t=2.00, P=0.049), plasma B-type natriuretic peptide (BNP) concentrations (t=3.48, P<0.001), and PWV (t=2.99, P=0.004). PWV was positively related to augmentation pressure (t=4.09, P<0.001), central systolic BP (t=3.13, P=0.002), and plasma BNP concentrations (t=3.54, P<0.001). Conclusions: This study shows that the increase in serum FGF23 concentrations reflects deterioration of phosphate homeostasis and is an important predictor for arterial stiffness, which intensifies cardiac afterload.

[Effective TS-1+paclitaxel administration for gastric cancer with malignant ascites--a case report].

We report a case in which TS-1 + paclitaxel (PTX) administration was effective for gastric cancer with malignant ascites. The patient was a 66-year-old male who received total gastrectomy, distal pancreatectomy and splenectomy. He complained of abdominal fullness and ascites 18 months later. The administered regimen of chemotherapy was TS-1 100 mg/day for two weeks, and PTX 120 mg/day on day 1 and 8 of TS-1 intake, followed by 1-week rest. Computed tomography (CT) showed complete loss of malignant ascites. The toxic events were grade 2 leukopenia and grade 2 alopecia.

[A clinical study of hepatic arterial infusion chemotherapy with low-dose CDDP and 5-FU for liver metastases].

We followed patients who underwent hepatic arterial infusion chemotherapy with low-dose CDDP+5-FU for liver metastases from colorectal cancer in the outpatient setting. A catheter was inserted from the femoral artery into the proper hepatic artery using the interventional technique. Two complete response (CR) and seven partial response (PR) were achieved, but later 2 of these patients had lung metastases. We conclude that this therapy may be effective, but control of extrahepatic lesions is necessary for life prolongation.

[Antispasm therapy using combination of midazolam and propofol for severe tetanus].

A 68-year-old healthy woman without any evidence of recent wound, developed nuchal pain, difficulty in swallowing and trisumus in 10 days. Because of respiratory failure due to generalized muscle spasm, she was intubated and required mechanical ventilation. Midazolam was administered as an antispastic therapy followed by human tetanus immune globulin and tetanus toxoid. Propofol was added on 9 days after intubation, since muscle spasm such as opisthotonus or respiratory spasm did not improve under midazolam and intermittent administration of vecuronium. Thereafter, her muscle spasm and hypertensive response were well controlled. The authors suggested that a combined use of midazolam and propofol was an optional antispastic therapy in patients with severe tetanus.
