Abstract Background There is a dearth of information on liver abscesses in the United Arab Emirates. Herein, we describe the clinical features of liver abscesses and determine their incidence rates and clinical outcomes. Methods We retrospectively reviewed the clinical charts of adult patients with a primary diagnosis of liver abscess at a major hospital over a 7-year period. Results Amongst 45 patients, 82.2% (37/45) had a pyogenic liver abscess (PLA) and 17.8% (8/45) had amoebic liver abscesses (ALA). Overall, patients were young (median age 42 years, IQR 35–52), mostly males (77.8%, 35/45) from the Indian subcontinent (55.6%, 25/45), presented with fever (88.9%, 40/45) and abdominal pain (88.9%, 40/45), and had a solitary abscess on imaging (71.1% (32/45). Crude annual incidence rates were 35.9/100,000 hospital admissions (95% CI 26.2–48.0) and 5.9/100,000 inhabitants (95% CI 4.3–7.9). All ALA patients were from the Indian subcontinent (100%, 8/8). Klebsiella pneumoniae was the most frequent pathogen in PLA (43.2% [16/37], 95% CI 27.1–60.5%). The hospital stay was shorter in ALA (7.5 days, IQR 7–8.5) than in PLA (14 days, IQR 9–17). No deaths were recorded within 30 days of hospitalisation. Conclusions ALA was exclusively seen in migrants from the Indian subcontinent, suggesting importation. Further research to characterise K. pneumoniae isolates and assess potential risk factors is needed.

Klebsiella pneumoniae (K. pneumoniae) is a common pathogenic bacteria that causes numerous infectious diseases. Hypervirulent K. pneumoniae (hvKP) can lead to invasive K. pneumoniae liver abscess syndrome, which can induce life-threatening multiple organ dysfunction syndrome or septic shock. We report a case of invasive K. pneumoniae liver abscess syndrome caused by hvKP and discuss the treatment options of this syndrome. Appropriate antimicrobial drugs should be administered to improve prognosis and prevent complications, and laboratory testing is essential to guide clinical management and optimize patient outcomes.

ABSTRACTKlebsiella pneumoniaeliver abscess (KPLA) is prevalent in East Asia. Liver abscess can develop after translocation ofK. pneumoniaefrom a patient's bowel into the liver via the portal circulation. TREM-1 (triggeringreceptorexpressed onmyeloid cells1) amplifies inflammatory signaling during infection, but its role in KPLA is poorly understood. We used an animal study to characterize the role of TREM-1 in KPLA. We compared survival rates, bacterial burdens in tissues, inflammatory cytokine levels, and histology findings between wild-type andTrem-1knockout (KO) mice after oral inoculation of capsular type K1K. pneumoniae. Translocation ofK. pneumoniaeto mesenteric lymph nodes and liver was examined, and intestinal permeability, antimicrobial peptide expression, and the clearance ofK. pneumoniaein the small intestine were determined. In the absence of TREM-1, KPLA model mice showed increasedK. pneumoniaedissemination, enhanced liver and systemic inflammation, and reduced survival. Impaired bacterial clearance in the small intestine causes enhancedK. pneumoniaetranslocation, which rendersTrem-1KO mice more susceptible toK. pneumoniaeoral infection. In conclusion, TREM-1-mediated bacterial clearance in the small intestine is an important immune response againstK. pneumoniae. TREM-1 deficiency enhancesK. pneumoniaetranslocation in the small intestine and increases mortality rates in mice with KPLA.

Abstract Background: Klebsiella pneumoniae is considered the most clinically relevant species of Enterobacteriaceae, known to cause severe infections including liver abscesses. To the best of our knowledge, a large proportion of iron in the human body is accumulated and stored in the liver. We hypothesize that increased iron availability is an important factor driving liver abscess formation and we therefore aim to understand the effects of iron on K. pneumoniae causing liver abscesses. Results: All tested K. pneumoniae clinical isolates, including those isolated from liver abscesses and other abdominal invasive infection sites, grew optimally when cultured in LB broth supplemented with 50 μM iron and exhibited the strongest biofilm formation ability under those conditions. Decreased growth and biofilm formation ability were observed in all tested strains when cultured with an iron chelator (P<0.05). The infection model of G. mellonella larvae indicated the virulence of liver abscess-causing K. pneumoniae (2/3) cultured in LB broth with additional iron was significantly higher than those under iron-restricted conditions (P<0.05). The relative expression levels of the four siderophore genes (iucB, iroB, irp1, entB) in K. pneumoniae strains isolated from liver abscesses cultured with additional iron were lower than those under iron-restricted conditions (P<0.05). Conclusions: It is suggested by our research that iron in the environment can promote growth, biofilm formation and enhance virulence of K. pneumoniae causing liver abscesses. A lower expression of siderophore genes correlates with increased virulence of liver abscess-causing K. pneumoniae. Further deeper evaluation of these phenomena is warranted.
