Parainfluenza tipo 3 en una unidad de trasplante
JAMA
|January 26, 1979
Resumen
Los brotes de virus de parainfluenza tipo 3 en pacientes trasplantados de riñón causaron episodios de rechazo más agudos. Sin embargo, las tasas de supervivencia del paciente y del injerto a los seis meses no se vieron afectadas por la infección viral.
Área de la Ciencia:
- Nefrología Nefrología.
- Enfermedades infecciosas Enfermedades infecciosas.
- Inmunología del trasplante Inmunología del trasplante.
Sus antecedentes:
- El virus de la parainfluenza tipo 3 (PIV3) puede causar una morbilidad significativa en individuos inmunocomprometidos.
- Los receptores de trasplante renal son particularmente vulnerables a las infecciones oportunistas debido a la inmunosupresión.
- El impacto de la infección por PIV3 en los resultados del trasplante renal requiere una mayor aclaración.
Objetivo del estudio:
- Para investigar la presentación clínica y el impacto de una epidemia de infección viral por PIV3.
- Para evaluar el efecto de la infección por PIV3 en la función del trasplante renal y los resultados del paciente.
- Para comparar los resultados entre los receptores de trasplante renal infectados y no infectados.
Principales métodos:
- Diseño del estudio de cohorte retrospectivo.
- La inclusión de 16 recientes receptores de trasplante renal con infección por PIV3.
- Comparación con un grupo de control emparejado de receptores de trasplante renal no infectados.
Principales resultados:
- Infección por PIV3 presentada con síntomas leves de infección del tracto respiratorio superior.
- Se observó un aumento significativo en los episodios de rechazo agudo en pacientes infectados durante el período de infección.
- No hay diferencia significativa en la supervivencia del paciente y del injerto a los seis meses entre los grupos infectados y de control.
Conclusiones:
- La infección por PIV3 en receptores de trasplante renal se asocia con un mayor riesgo de rechazo agudo.
- A pesar del aumento de los episodios de rechazo, la infección por PIV3 no afectó negativamente la supervivencia a corto plazo del paciente o del injerto.
- El monitoreo cercano de la infección por PIV3 y el manejo rápido del rechazo son cruciales en los receptores de trasplante renal.

Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Acute Respiratory Failure-II
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Acute Respiratory Failure-III
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without causing...
Kidney Transplant III: Nursing Management
Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...
Influenza
Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...
Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
