まとめ
慢性イディオパシー性ウルティカリア (CIU) 患者におけるヒスタミンを放出する自己抗体が,プラズマフェレスで標的とされた. この治療は,一部において有意な症状緩和をもたらし,オートアンチボディがCIUの病原性において重要な役割を果たすことを示唆した.

背景:
- ヒスタミンを放出する自己抗体は,慢性イディオパシー性ウルティカリア (CIU) に関わっている.
- 重度のCIU症例では,しばしば血清でヒスタミン放出活性を示します.
研究 の 目的:
- 重症疾患のCIU患者に対するプラズマフェレシスの治療効果を調査する.
- CIUの病原性におけるヒスタミンを放出する自己抗体の役割を調査する.
主な方法:
- プラズマフェレシスは,重度のCIUとヒスタミン放出性血清活性を有する8人の患者に実施されました.
- オートログの血清と皮内ヒスタミンに対する皮膚検査の反応は,プラズマフェレシス前と後の評価が行われました.
- 血液細胞ヒスタミンとインビトロ血清ヒスタミン放出活性が測定されました.
主要な成果:
- 症状の緩和は様々で,2例の患者で完全回復,2例の患者で一時的な緩和,2例の患者で最小限の変化が見られた.
- プラズマフェレシス後の血清は,交換前の血清と比較して,皮膚検査の反応が低下したことを示した.
- 血液ヒスタミン濃度が上昇し,インビトロ血清ヒスタミン放出活性が術後減少した.

Dialysis
Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications
Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
Chronic Kidney Disease I: Introduction
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...
Chronic Kidney Disease III: Interprofessional Care
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
