Klebsiella pneumoniae-Induced Multiple Infections in a Diabetes Mellitus Patient: Pneumonia, Liver Abscess, Endogenous Endophthalmitis, Urinary Tract Infection

Klebsiella pneumoniae-induced endogenous endophthalmitis is a rare but devastating disease, which usually occurs in immunosuppressed patients. Poorly controlled diabetes mellitus is a significant risk factor for this disease. The most common distant infection in patients with K. pneumoniae-induced endogenous endophthalmitis was reported to be liver abscess. Other less commons distant infections were found to be catheter-related bloodstream infection, urinary tract infection, soft tissue infection, renal and psoas abscesses, and endocarditis. Patients with coexisting multiple infection sites are rare according to previous studies. These patients may have a high risk of sepsis and death. Here, we present a case of a 64-year-old male who presented with a progressive visual disturbance with general malaise. A K. pneumoniae-induced endogenous endophthalmitis was suspected. After surveying distant infection sites, pneumonia, liver abscess, and urinary tract infection were reported. This paper also describes the clinical features of endogenous endophthalmitis and highlights K. pneumoniae-induced multiple infections in a diabetes mellitus patient, thus providing information that will be useful for physicians to perform timely interventions and avoid sepsis.
