Progression of anemia in patients with chronic kidney disease (CKD) is associated with an increased risk of death and hospitalization. It is not sufficiently clear whether treating renal anemia with recombinant human erythropoietin (rHuEPO) has a beneficial effect on early survival after hemodialysis (HD) initiation in patients with CKD. The study was an(More)
This Japanese nation-wide survey was carried out on long-term survivors among children with leukemia, i.e. those who had survived more than 5 years by October of 1974. Eighty-three children were surveyed. This was about 2.5 times as many as the 31 children surveyed in the first Japanese nation-wide survey in 1971. Clinical and laboratory data were also(More)
We have evaluated the relation between cancer of the lower urinary tract ("bladder cancer") and the use of artificial sweeteners, by means of case-control studies in Manchester, U.K., and Nagoya, Japan, areas where extensive use occurred 30-40 years ago. In each area, a broadly based series of cases (555 in Manchester, 293 in Nagoya) was interviewed and a(More)
The effect of recombinant human erythropoietin (rHuEPO) treatment on the progression of chronic kidney disease (CKD) has not been fully evaluated in Japan. We therefore retrospectively evaluated this in a sub-cohort of a prospective multicenter study to investigate optimal hemoglobin (Hb) level of CKD patients on hemodialysis (HD) treated with rHuEPO; Japan(More)
BACKGROUND Attitudes of healthcare professionals regarding spontaneous reporting of adverse drug reactions (ADRs) in Japan are not well known, and Japan's unique system of surveillance, called early post-marketing phase vigilance (EPPV), may affect these reporting attitudes. Our objectives were to describe potential effects of EPPV and to test whether ADR(More)
Although erythropoiesis-stimulating agents (ESAs) are effective at treating anemia, the association between hemoglobin (Hb) levels and survival is still unclear, especially for the incident Japanese hemodialysis (HD) population. The Japan Erythropoietin Treatment (JET) Study is an open multi-center, prospective, observational study designed to evaluate the(More)
BACKGROUND Although several reports have suggested that patient-generated data from Internet sources could be used to improve drug safety and pharmacovigilance, few studies have identified such data sources in Japan. We introduce a unique Japanese data source: tōbyōki, which translates literally as "an account of a struggle with disease." OBJECTIVE The(More)
