Disorders of Leukocytes01:27

Disorders of Leukocytes

749
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Burn Injuries

2.3K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Factors Affecting Renal Clearance: Renal Impairment

36
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Nephrons

1.7K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Dialysis

235
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...

Kidney Structure01:45

Kidney Structure

67.2K
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

  • 腎臟醫學 腎臟醫學
  • 血液学 血液学 血液学

背景情况:

  • 白细胞症是由于系统性炎症导致的烧伤的常见反应.
  • 虽然烧伤后72-96小时全白细胞计数 (TLC) 的下降是典型的,但早期白血病 (<72小时) 描述不好.
  • 了解TLC的早期变化可能会揭示与复苏需求和结果的关联.

研究的目的:

  • 确定烧伤后早期,极度减少的白细胞总数 (TLC) 是否与增加的液体复苏需求有关.
  • 调查早期TLC降低和复苏相关并发症之间的关系,包括急性损伤 (AKI) 和肌球蛋白尿.
  • 评估烧伤患者早期TLC降低和7天生存率之间的关联.

主要方法:

  • 来自Burn Navigator数据库的295名烧伤患者 (>20%TBSA,>40kg) 的分析,他们使用临床决策支持系统进行了复苏.
  • 根据入院后TLC的减少,患者被分为两组:>15,000细胞/μL与<15,000细胞/μL.
  • 收集的数据包括人口统计,复苏量,并发症 (肌红蛋白尿,AKI) 和7天生存率,并对TBSA进行调整.

主要成果:

  • 在TLC下降>15,000细胞/μL的患者有显著更高的全厚烧伤率和更大的TBSA.
  • 超过15,000个细胞/μL的TLC下降与在48小时内接受肌球蛋白尿和AKI的发生率明显增加有关,即使在TBSA调整后也是如此.
  • 当对TBSA进行调整时,七天生存率在两组之间没有显著差异.

结论:

  • 在烧伤患者中,白细胞计数 (WBC) 在治疗后至少减少15,000个细胞/μL,这与早期的AKI和肌球蛋白尿增加有关.
  • 早期白血病和不良结果 (如AKI和肌球蛋白尿) 之间的这种关联需要进一步调查.
  • 未来的研究应该探索这种观察到的关联的潜在早期干预和潜在早期干预的潜在机制.
