Case report: A case of high virulence and multidrug resistant Klebsiella pneumoniae liver abscess in Ningxia, China.

ABSTRACT

RATIONALE Highly virulent multidrug-resistant Klebsiella pneumoniae (KP) is becoming more and more common in clinical practice, especially the rise of carbapenem-resistant KP in clinical practice, resulting in the emergence of KP liver abscess in Ningxia, China. For the prognosis of liver abscess patients, it is particularly important to identify the types of pathogens and identify antibiotics that are sensitive to the pathogens. PATIENT CONCERNS A 73-year-old man from China presents to our hospital with abdominal pain, jaundice and fever. Patients have no obvious cause of abdominal pain, abdominal distension, and abdominal pain is persistent. Abdominal examination showed hepatomegaly, no tenderness 2 cm from the right costal margin, abdominal distension and other general examinations did not have obvious abnormalities. He had no history of hypertension and diabetes, ERCP was performed for cholangiocarcinoma 1 year before the current visit, and no significant complications occurred. DIAGNOSES His initial diagnosis was obstructive cholangitis, and computed tomographic images and liver drainage fluid bacterial culture and genetic polymerase chain reaction tests later determined that the patient had KP liver abscess. INTERVENTIONS: Drainage by liver catheter and antibiotic treatment for 7 weeks. OUTCOMES: The patient liver abscess is basically gone. LESSION It is particularly important to optimize the diagnosis of liver abscess pathogens for timely and effective treatment of patients.
