Introduction:
In recent years, hypervirulent Klebsiella pneumoniae (hvKp) has attracted increasing attention. It usually causes liver abscesses, which spread through the bloodstream to other parts such as the eyes, brain, lungs. 5.5% of all paroxysmal sympathetic hyperactivity syndrome are associated with infection, hydrocephalus, brain tumors, and some unknown causes. Younger patients with focal lesions of the brain parenchyma are at higher risk of paroxysmal sympathetic hyperactivity (PSH).
Case Presentation:
This case report details the clinical features of Klebsiella pneumoniae diagnosed in a healthy individual. In addition to liver abscesses, bacteremia, and hyperglycemia, there are also brain abscesses, hernias, and postoperative paroxysmal sympathetic hyperactivity, an unexpected association between diseases or symptoms. The patient stabilized after comprehensive treatment, including early drainage of abscesses, rapid pathogen diagnosis, and timely and appropriate antibiotics. At a two-month follow-up, no signs of infection recurrence were noted, and the patient regained neurological function and could participate in regular physical activity.
Discussion:
Symptoms of Klebsiella pneumoniae infection usually appear gradually, and misdiagnosis is common. When young patients suddenly develop high fever and abscess at a particular site, Klebsiella pneumoniae infection should be considered routine. Paroxysmal sympathetic hyperactivity syndrome caused by infection is rare, but a clinical score (PSH assessment measure, PSH-AM score) should be performed when clinical features appear. Early diagnosis and treatment can improve the prognosis.
Insights
Hypervirulent Klebsiella pneumoniae can cause severe infections, including liver and brain abscesses. Early diagnosis and treatment are crucial for recovery, even in rare cases involving paroxysmal sympathetic hyperactivity.
Area of Science:
- Infectious Diseases
- Neurology
- Critical Care Medicine
Background:
- Hypervirulent Klebsiella pneumoniae (hvKp) is an emerging pathogen causing severe infections, including liver abscesses that can disseminate to other organs.
- Paroxysmal sympathetic hyperactivity (PSH) is a rare syndrome, with a small percentage linked to infections, brain tumors, or unknown causes.
- Younger patients with focal brain lesions face a higher risk of developing PSH.
Observation:
- This case report describes a healthy individual with Klebsiella pneumoniae infection presenting with liver abscesses, bacteremia, hyperglycemia, brain abscesses, and postoperative paroxysmal sympathetic hyperactivity.
- The patient's condition improved with comprehensive treatment, including abscess drainage, rapid pathogen identification, and appropriate antibiotics.
- Neurological function was regained, and the patient could resume regular physical activity within two months.
Findings:
- Klebsiella pneumoniae infections can present insidiously, leading to common misdiagnoses.
- Sudden onset of high fever and localized abscess in young patients warrants consideration of Klebsiella pneumoniae infection.
- Infectious causes of PSH are rare but should be suspected, with clinical scoring (PSH-AM) recommended.
Implications:
- Prompt diagnosis and management of Klebsiella pneumoniae infections, even with unusual presentations like PSH, are vital for favorable outcomes.
- Raising clinical suspicion for hvKp in young patients with unexplained fever and abscesses is essential.
- Further research into the link between hvKp and PSH may uncover new diagnostic and therapeutic strategies.
