PURPOSE To detect the mechanism of intraocular pressure elevation during hemodialysis. METHODS We measured intraocular pressure, as well as serum osmolality and plasma CO2 pressure, every 30 min during hemodialysis, in 5 eyes with severely compromised aqueous outflow facility (Group A) from 4 renal failure patients. The same measurements were repeated on(More)
BACKGROUND beta2-microglobulin (beta2-m) is considered a major pathogenic factor in dialysis-related amyloidosis (DRA), often seen in long-term dialysis patients. No effective therapy for this severely debilitating disease is currently available. Lixelle, an adsorption column, has been developed for the elimination of beta2-m; the efficacy of this column(More)
We report on a case of factor VIII inhibitor-positive acquired hemophilia in which combined therapy of plasma exchange (PE) and steroids was effective. The patient, a 68-year-old man, had undergone hemodialysis since April 1998, due to chronic renal failure caused by diabetic nephropathy. The hemostasis of blood access sites gradually became difficult after(More)
A 55-year-old man was admitted to our hospital because of myelopathy. He had a history of chronic renal failure due to polycystic kidney disease at the age of 39, being treated by hemodialysis for 9 years with several blood transfusions for the treatment of renal anemia. After cadaver renal transplantation at the age of 48, he discontinued hemodialysis. At(More)
A 71-year-old woman was admitted to the Wakayama Medical University Hospital with dizziness and loss of body balance. She had started hemodialysis at the age of 70. During the 33 days before admission, she received oral tizanidine hydrochloride at 3 mg/day for leg cramps. An admission electrocardiogram (ECG) demonstrated sinus bradycardia of 47 bpm. A 24-h(More)
Plasma exchange (PE) is often performed in combination with hemodialysis (HD) or hemodiafiltration. However, most methods were developed for the treatment of renal failure, so various problems may arise during treatment of liver failure (LF). In this study, we investigated the impact of PE alone and in combination with HD, and we assessed the complications(More)
Hemodialysis is essential for the survival of patients suffering from chronic renal failure. However, in diabetics the incidence of dry eye disease is higher than in non-diabetic individuals. Accordingly, we evaluated if this difference is attributable to different effects of hemodialysis on basal tear fluid secretion. A modified Schirmer´s eye test(More)
We experienced a case of thrombotic thrombocytopenic purpura (TTP) finally relieved after 74 sessions of plasma exchange (PE). The patient was a 56-year-old male. In August 1999, he was examined in emergency because of brown urine and a lowered level of consciousness. As TTP was suspected according to the laboratory findings of abnormally high lactate(More)
Bullous pemphigoid (BP) is an autoimmune disease caused by an antidermal basal lamina antibody. In recent years double filtration plasmapheresis (DFPP) has been reported to be an effective therapy for BP. We experienced 3 cases of BP treated by DFPP. DFPP resulted in an improvement in clinical symptoms and remission allowing a decrease in the required dose(More)
