Investigation of treatment volume versus circulating blood volume during Rheocarna treatment.

Introduction: Rheocarna's therapeutic effect is associated with fibrinogen (Fib) and low-density lipoprotein cholesterol (LDL-C) adsorptive removal. This study aimed to retrospectively investigate the association between treatment volume (TV) and circulating blood volume (CBV) and the Fib removal rate (Fib-RR) and LDL-C-RR.

Methods: CBV and TV/CBV, cut-off value (CO value), and area under the receiver operating characteristic (ROC) curve (AUC) were calculated.

Evaluation of the treatment volume and removal rate of Rheocarna: A novel adsorption-type blood purification device for patients with chronic limb-threatening ischemia.

Introduction: Chronic limb-threatening ischemia (CLTI) is a clinical syndrome defined by peripheral arterial disease (PAD) combined with rest pain, gangrene, or leg ulceration for longer than two weeks resulting in lower extremity amputation. In recent years, low-density lipoprotein apheresis (LDL-A) has been implemented for PAD treatment. However, it has not been possible to ensure insurance coverage for patients with lower LDL levels than 140 mg/dL under cholesterol-lowering drugs.

Low-Density Lipoprotein Adsorption by Centrifugal Plasma Separation Can Shorten Treatment Time.

Low-density lipoprotein (LDL) apheresis is effective for nephrotic syndrome in drug-resistant focal segmental glomerulosclerosis (FSGS). Dextran sulfate adsorption of LDL (DSAL) is widely used for this purpose. The Liposorber LA-15 system performs DSAL by membrane plasma separation (mDSAL) using an MA-03 plasma purification device.

Adjustment by hematocrit level in calculation of removal rate in therapeutic apheresis.

Plasma volume (PV) variation during therapeutic apheresis (TA) (such as plasma exchange [PE] and selective PE using albumin solution as replacement solution or immunoadsorption plasmapheresis) has been considered to be unignorable. It changes the concentration of the target molecule and might impact its removal rate (RR.) This study aimed to evaluate the effects of PV variation on the calculation of the RR of fibrinogen and immunoglobulin by categorizing the hematocrit (Ht) change during TA into two patterns, that is, increased group and decreased group.

Removal Characteristics of Immunoadsorption with the Tryptophan-Immobilized Column Using Conventional and Selective Plasma Separators in the Treatment of Myasthenia Gravis.

Autoimmune neurological diseases are often treated by immunoadsorption using a conventional plasma separator and tryptophan-immobilized column (IA). However, there is only one case report on treatment with immunoadsorption using a selective plasma separator and tryptophan-immobilized column (SeIA) in clinical practice. This study aimed to investigate the removal characteristics of antibodies against acetylcholine receptors (AChRAb), immunoglobulin G, fibrinogen, and factor XIII (FXIII) in IA and SeIA in four patients with myasthenia gravis.

Removal Dynamics of Autoantibodies, Immunoglobulins, and Coagulation Factors by Selective Plasma Exchange on Three Consecutive Days.

Selective plasma exchange has been shown to be effective in various diseases, but no studies have assessed the benefits of daily treatment. We aimed to investigate the removal dynamics of immunoglobulins, fibrinogen, and factor XIII on three consecutive days in three patients. For mean processed plasma volumes of 1.

Selective plasma exchange.

Selective plasma exchange (SePE) is a new modality of simple plasma exchange that uses a selective membrane plasma separator Evacure EC-4A10 (EC-4A) (Kawasumi Laboratories Inc., Tokyo, Japan). EC-4A has a relatively small pore size of 0.

Fibrinogen Reduction During Selective Plasma Exchange due to Membrane Fouling.

Fibrinogen is substantially reduced by most plasmapheresis modalities but retained in selective plasma exchange using Evacure EC-4A10 (EC-4A). Although EC-4A's fibrinogen sieving coefficient is 0, a session of selective plasma exchange reduced fibrinogen by approximately 19%. Here, we investigated sieving coefficient in five patients.

Selective Plasma Exchange for the Removal of Pemphigus Autoantibodies, Fibrinogen, and Factor XIII in Pemphigus Vulgaris.

Pemphigus vulgaris is a serious autoimmune skin disorder associated with desmoglein 1 and 3. Selective plasma exchange (SePE) for pemphigus vulgaris remains unknown. We investigated the removal characteristics of pemphigus autoantibodies, immunoglobulins, and fibrinogen in three cases.

Influence of proton pump inhibitors and histamine H receptor antagonists on serum phosphorus level control by calcium carbonate in patients undergoing hemodialysis: a retrospective medical chart review.

Background: Hyperphosphatemia is one of the common complications in patients undergoing hemodialysis. Although calcium carbonate (CaC) is often used to control serum inorganic phosphorus level in dialysis patients, co-administration of gastric acid reducers (ARs) may interfere with the phosphate binding effect of CaC. We performed a retrospective medical chart review to study whether ARs attenuate the hypophosphatemic effect of CaC in patients undergoing hemodialysis.

Removal Characteristics of Immunoadsorption With the Immusorba TR-350 Column Using Conventional and Selective Plasma Separators.

In Japan, immunoadsorption (IA) is performed using a conventional plasma separator and Immusorba TR-350 column (TR-350) for the treatment of neurological immune diseases. By this method, TR-350 has the limited maximal capacity of the immunoglobulin G (IgG) adsorption, and fibrinogen (Fbg) is reduced remarkably. Evacure EC-4A10 (EC-4A) is a selective plasma separator and the sieving coefficients of IgG and Fbg using EC-4A were 0.

Removal Dynamics of Immunoglobulin and Fibrinogen by Conventional Plasma Exchange, Selective Plasma Exchange, and a Combination of the Two.

While plasma exchange (PE) can eliminate plasma proteins, including all immunoglobulin (Ig) and coagulation factors, selective plasma exchange (SePE) can retain fibrinogen (Fbg). Here, we investigated the removal dynamics of Ig and Fbg in 53 patients with immunological disorders by PE, SePE, and a combination of the two. When the mean processed plasma volume (PPV) was 0.

SLAP repair with arthroscopic decompression of spinoglenoid cyst.

Introduction: A spinoglenoid cyst with suprascapular nerve disorders is highly associated with superior labrum anterior posterior (SLAP) lesion. Conservative or surgical treatment is applied to relieve pain and neurological symptoms. The purpose of this study was to evaluate clinical outcomes of patients treated by arthroscopic surgery for SLAP lesion with a spinoglenoid cyst.

Removal Characteristics of Immunoglobulin G Subclasses by Conventional Plasma Exchange and Selective Plasma Exchange.

Selective plasma exchange (SePE) using a selective membrane separator is a modified method of simple plasma exchange (PE). Immunoglobulin G (IgG) subclass distribution is one of the important immunological characteristics of IgG. However, there is little information regarding the removal characteristics of IgG subclasses by SePE and conventional PE.

Stress fracture of the radial styloid process in a judo player: a case report.

Stress fractures of the upper limbs are uncommon, and are most often reported as individual cases or small series. In particularly, stress fractures around the wrist are even less common. A stress fracture of the radial styloid process in a judo player was surgically treated, and a favorable treatment outcome was obtained.

The outcome of hemiarthroplasty for proximal humeral fractures is dependent on the status of the rotator cuff.

Purpose: The purpose of this study was to evaluate clinical and radiological outcomes of hemiarthroplasty for proximal humerus fractures.

Methods: Thirty-five patients (33 women and two men), average age at the time of surgery of 75.1 (range, 64-92) years, who underwent hemiarthroplasty for proximal humerus fracture or fracture-dislocation of the shoulder were enrolled in this study.

Removal kinetics of antibodies against glutamic acid decarboxylase by various plasmapheresis modalities in the treatment of neurological disorders.

Plasmapheresis is one of the acute treatment modalities for neurological disorders associated with antibodies against glutamic acid decarboxylase (anti-GAD). However, there is little information about the removal kinetics of anti-GAD by various plasmapheresis modalities. Here, we investigated the removal rate of anti-GAD and fibrinogen (Fib) by immunoadsorption (IA), plasma exchange using a conventional plasma separator (OP-PE), and plasma exchange using a high cut-off selective membrane plasma separator (EC-PE) in two cases of anti-GAD-associated neurological diseases.

Solute removal capacity of high cut-off membrane plasma separators.

In vitro blood filtration was performed by a closed circuit using high cut-off membrane plasma separators, EVACURE EC-2A10 (EC-2A) and EVACURE EC-4A10 (EC-4A). Samples were obtained from sampling sites before the plasma separator, after each plasma separator, and from the ultrafiltrate of each separator. The sieving coefficient (S.

Effects of kojic acid on thyroidal functions in rats by single-dose administration and in cultured rat thyroid cells (FRTL-5 cells).

The effects of kojic acid (KA) on thyroidal function were studied by single-dose administration in rats and in cultured rat thyroid cells (FRTL-5 cells). In rats receiving a single dose of 1,000 mg/kg KA orally, the 125I uptake from blood into the thyroid gland was significantly lower than that of the control group from 30 min to 24 hr after administration. The 125I organification activity of the KA groups was significantly lower than control from 30 min to 6 hr after administration.
