Insights

Intensive plasma exchange (IPE) or whole blood exchange (WBE) effectively treated coagulopathy in critically ill children with meningococcemia. This procedure improved coagulation markers and survival rates without causing fluid overload.

Area of Science:

  • Pediatric Critical Care Medicine
  • Hematology
  • Infectious Diseases

Background:

  • Fulminant meningococcemia presents with purpura and disseminated intravascular coagulation (DIC), often leading to poor prognoses.
  • Standard medical therapy may be insufficient for critically ill pediatric patients with severe coagulopathy.

Purpose of the Study:

  • To evaluate the safety and efficacy of intensive plasma exchange (IPE) or whole blood exchange (WBE) in pediatric patients with fulminant meningococcemia and DIC.
  • To assess the impact of IPE/WBE on coagulation parameters and patient outcomes.

Main Methods:

  • Eight pediatric patients with fulminant meningococcemia, purpura, and DIC received IPE/WBE in addition to standard therapy.
  • IPE/WBE utilized fresh frozen plasma and cryoprecipitate as replacement solutions, performed with a continuous flow system.
  • Coagulation parameters (fibrinogen, PT, APTT) and fluid balance were monitored.

Main Results:

  • IPE/WBE rapidly improved coagulation parameters: fibrinogen increased, PT and APTT decreased significantly.
  • Seven of eight patients (87.5%) survived the initial presentation; the only early death was due to meningitis with cerebral edema.
  • The procedure was safe, with no significant bleeding or cardiovascular complications, and no evidence of fluid overload.

Conclusions:

  • IPE/WBE is a safe and effective therapeutic option for critically ill pediatric patients with meningococcemia-induced coagulopathy.
  • This exchange therapy can rapidly correct coagulopathy without inducing fluid overload, improving survival in high-risk patients.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

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...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
