Bacteremia aguda en pacientes de trasplante renal asplenico
JAMA
|May 16, 1977
Resumen
Los receptores de trasplante de riñón asplénico pueden enfrentar un alto riesgo de bacteriemia abrumadora, similar a la sepsis post-esplenectomía. La extirpación del bazo, en lugar de la inmunosupresión, parece ser el principal factor de riesgo para estas infecciones tardías.
Área de la Ciencia:
- Nefrología Nefrología.
- Inmunología Inmunología.
- Enfermedades infecciosas Enfermedades infecciosas.
Sus antecedentes:
- Los receptores de trasplante renal a menudo experimentan infecciones debido a la inmunosupresión.
- La sepsis abrumadora post-esplenectomía es un riesgo conocido en individuos asplenicos.
Objetivo del estudio:
- Para investigar la bacteriemia abrumadora de aparición tardía en pacientes de trasplante renal asplenico.
- Determinar los factores de riesgo primarios para estas infecciones después del trasplante.
Principales métodos:
- Análisis de la serie de casos de cuatro pacientes con trasplante renal asplenico.
- Revisión de los hallazgos bacteriológicos y la presentación clínica de las infecciones.
Principales resultados:
- Cuatro casos de bacteriemia abrumadora ocurrieron entre 12 y 20 meses después del trasplante.
- Las infecciones imitaban las presentaciones clásicas de sepsis post-esplenectomía.
- Los pacientes estaban en tratamiento de inmunosupresión con azatioprina y prednisona.
Conclusiones:
- La asplenia, no la inmunosupresión, es el probable factor predisponente para estas infecciones tardías.
- El estado asplénico plantea un riesgo significativo de sepsis en los receptores de trasplante renal.
- Estas infecciones poco comunes resaltan el papel crítico del bazo en la defensa inmune.

01:26Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

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...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
