[PMID: 39286224 PMCID: PMC11402988 DOI: 10.1016/j.heliyon.2024.e37050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 08/25/2024] [Accepted: 08/27/2024] [Indexed: 09/19/2024] Open
Abstract
Objectives Our objective was to establish a rapid and precise method for detecting hypervirulent Klebsiella pneumoniae (hvKP) by utilizing a duplex real-time multienzyme isothermal rapid amplification (real-time MIRA) and to evaluate its performance in clinical spiked blood specimens. Methods The research comprised two phases: an initial pilot study to establish the methodology and a clinical validation study to assess its effectiveness. In the pilot phase, we designed specific primers and probes targeting the hvKP pg344 and incA genes and subsequently developed a duplex real-time MIRA assay to evaluate its detection limits, specificity, and efficiency. In the clinical validation phase, we analyzed thirty-three spiked blood specimens using the duplex real-time MIRA assay. Results The duplex real-time MIRA assay demonstrated no cross-reactivity with other strains. Sensitivity experiments confirmed that the assay had a detection limit as low as 8 × 102 CFU per reaction for hvKP. The analysis of clinical spiked blood specimens indicated that the sensitivity and specificity of the duplex real-time MIRA assay were on par with those of duplex real-time PCR. Conclusions These findings confirm that the duplex real-time MIRA assay is a fast, straightforward, and dependable method for detecting hvKP.

Abstract
Klebsiella endophthalmitis is a rare cause of endogenous endophthalmitis, with very few cases documented in the US. We present a male patient in his 60s with a history of latent tuberculosis who presented to the hospital with complaints of acute bilateral vision loss that began three days prior to admission. The workup revealed Klebsiella pneumoniae bacteremia, a large hepatic abscess, severe orbital swelling, and acute angle-closure glaucoma. The patient received intravitreal antibiotics, intravenous antibiotics, a hepatic drain, intraocular pressure-lowering medications, and steroids. Bacteremia was cleared with antibiotics and source control; however, vision loss did not improve. This case emphasizes the acuity and severity of Klebsiella endogenous endophthalmitis and outlines the need for immediate intervention with the onset of symptoms to prevent irreversible vision loss.

Abstract
This study assessed prognostic factors and the role of vitrectomy in patients with subretinal abscesses secondary to K. pneumoniae endophthalmitis. We reviewed published studies, including three cases from our cohort. Among 50 eyes, 26 had poor visual outcomes (final visual acuity <20/800, eyeball removal, or phthisis bulbi). Poor outcomes correlated with delayed ocular symptom-to-diagnosis time, initial visual acuity <20/800, severe vitritis, and macular involvement of abscesses (p < 0.001, p = 0.008, p < 0.001, and p = 0.033, respectively). Vitrectomy had a trend towards reducing eyeball removal and phthisis bulbi rates compared with non-vitrectomy (10.8% vs 30.8%, p = 0.181). However, the final visual acuity was not different and the rate of retinal detachment tended to be higher in vitrectomized eyes (45.9% vs 15.4%, p = 0.095). The study suggested that vitrectomy and drainage of K. pneumoniae subretinal abscesses could be avoided in patients with a mild degree of vitritis.

Abstract
PURPOSE To investigate the clinical features of endogenous Klebsiella pneumoniae endophthalmitis (EKPE) and the molecular characteristics of pathogenic K. pneumoniae. METHODS A retrospective study was conducted between January 2014 and January 2021. Clinical data were extracted. K. pneumoniae isolates cultured from EKPE patients' specimens were characterized by antimicrobial susceptibility testing, multilocus sequence typing, capsular serotyping, and virulence gene profiles. Virulence phenotypes were confirmed by mouse lethality assay. RESULTS Thirty-nine patients (47 eyes) were diagnosed with EKPE. Administration of systemic antibiotics and eye treatment within 24 hours of ocular symptom onset was statistically associated with better visual outcomes (p = .007). Sixteen K. pneumoniae isolates were collected, three of which were carbapenem-resistant and avirulent. Only salmochelin encoding gene was harbored by all isolates. CONCLUSIONS Systemic and eye treatment administered within 24 hours from the onset improves visual prognosis. Besides hypervirulent strains, avirulent carbapenem-resistant K. pneumoniae can cause EKPE.

Abstract
Endogenous endophthalmitis represents an ophthalmological emergency requiring immediate diagnostics and treatment. Pathogens should be detected using appropriate methods, such as the Freiburg endophthalmitis set. In bacterial endophthalmitis both Gram-positive and Gram-negative bacteria can be detected. Frequent underlying sources include endocarditis, gastrointestinal or urogenital surgery, indwelling venous catheters, liver abscesses, skin or soft tissue infections, meningitis or less commonly, intravenous drug abuse. The treatment consists of systemic and intraocular administration of antibiotics and vitrectomy. Systemic or intraocular corticosteroids can additionally be considered.

Abstract
CA is a plant derivative with antibacterial and antiviral pharmacological effects, however, the therapeutic effect of CA on Klebsiella pneumonia and its mechanism study is still unclear. A rat KP model was established in vitro, a pneumonia cell model was established in vivo, the histopathological changes in the lungs were observed by HE staining after CA treatment, the expression of relevant inflammatory factors was detected by ELISA, the changes in the expression of proteins related to the AhR-Src-STAT3-IL-10 signaling pathway were detected by Western blot and immunofluorescence in the lungs, and the interactions between the proteins were verified by COIP relationship. The results showed that CA was able to attenuate the injury and inflammatory response of lung tissues, and molecular docking showed that there were binding sites between CA and AhR, and COIP demonstrated that AhR interacted with both STAT3 and Ser. In addition, CA was able to up-regulate the expression levels of pathway-related proteins of AhR, IL-10, p-Src, and p-STAT3, and AhR knockdown was able to reduce LPS-induced inflammatory responses and up-regulate pathway-related proteins, whereas CA treatment of AhR-knockdown-treated A549 cells did not show any statistically significant difference compared with the AhR knockdown group, demonstrating that CA exerts its pharmacological effects. These findings elucidated the mechanism of CA in the treatment of KP and demonstrated that CA is a potential therapeutic agent for KP.

Abstract
Clinical practices on acute post-operative and endogenous endophthalmitis (EnE) are highly variable among clinicians due to a lack of up-to-date, high-quality evidential support. An expert consensus is thus much needed. A panel consisting of ten retinal specialists in Taiwan was organized. They evaluated relevant literature and developed key questions regarding acute post-operative and EnE that are cardinal for practice but yet to have conclusive evidence. The panel then attempted to reach consensus on all the key questions accordingly. There were eight key questions proposed and their respective consensus statements were summarized as follows: Gram staining and culture are still the standard procedures for the diagnosis of endophthalmitis. Vitrectomy is recommended to be performed earlier than the timing proposed by the Endophthalmitis Vitrectomy Study (EVS). Routine intracameral antibiotic injection for post-cataract surgery endophthalmitis prophylaxis is not recommended because of potential compounding error hazards and a lack of support from high-quality studies. Routine fundus examination is recommended for all patients with pyogenic liver abscess. In EnE, vitrectomy is recommended if diffused and dense vitritis is present, or if the disease progresses. These consensus statements may work as handy guidance or reference for clinical practices of acute post-operative and EnE.

Abstract
Introduction Endogenous endophthalmitis-related Klebsiella pyogenic liver abscess is a rare complication of metastatic infection. In most cases, visual acuity results are often impaired, even blind, and even with aggressive treatment with topical antibiotics, the final results are unsatisfactory. The objective of this study is to retrospectively based on medical records to describe clinical features, risk factors, and visual outcomes of patients with endogenous endophthalmitis-related pyogenic liver abscesses. Methods We reported a case series of 12 endogenous endophthalmitis-related pyogenic liver abscess patients from March 2021 to 2023. All cases of endogenous endophthalmitis were diagnosed at admission or during the hospital stay. Results From the medical records of 588 pyogenic liver abscess patients, we found 12 cases of endogenous endophthalmitis with 2.0%. The result showed a mean age of 61.5 ± 12.0 (41-78), diabetes mellitus (7 of 12), right lobe (7 of 12), single abscess (9 of 12), and the mean largest abscess diameter of 5.8 ± 1.7 cm (3.3-9). All patients had ocular symptoms such as eye pain (9 of 12), pus discharge (3 of 12), hypopyon (1 of 12), swollen eyelids (2 of 12), and corneal edema (2 of 12), pyogenic liver abscess before endogenous endophthalmitis (10 of 12), the median interval between endogenous endophthalmitis and pyogenic liver abscess 6.1 ± 1.9 days, ocular symptoms before diagnosis endogenous endophthalmitis 4.4 ± 2.3 days. All affected eyes were injected intravitreously with ceftazidime, amikacin, and vancomycin. Two patients underwent evisceration. Conclusions Endogenous endophthalmitis has permanent morbidity, reducing visual acuity, poor quality of life, and lacks the warning signs, so it is essential for early detection of symptoms and referral to ophthalmologists.

Abstract
Klebsiella pneumoniae bacteremia is known to present a virulent clinical course, including multiple metastatic infections, which is not uncommon in Asia. However, there are limited data on the incidence and risk factors for ocular involvement in K. pneumoniae bacteremia. We retrospectively reviewed the medical records of all patients with K. pneumoniae bacteremia who underwent ophthalmologic examination in a tertiary center in Seoul, Korea, from February 2012 to December 2020. Two retinal specialists reviewed the findings of the ophthalmologic examinations and classified them as endophthalmitis, chorioretinitis, and no ocular involvement. Of 689 patients, 56 [8.1%; 95% confidence interval (CI) 6.2-10.4] had ocular involvement, and 9 (1.3%; 95% CI 0.6-2.5) were diagnosed with endophthalmitis. Of 47 patients with chorioretinitis, 45 (95.7%) improved with systemic antibiotic therapy alone. Community-onset bacteremia (100% vs 62.1% vs 57.4%, P = 0.04), cryptogenic liver abscess (55.6% vs 11.8% vs 8.5%, P = 0.003), and metastatic infection (66.7% vs 5.8% vs 10.6%, P < 0.001) were more common in endophthalmitis than in no ocular involvement or chorioretinitis. In the multivariable analysis, cryptogenic liver abscess [adjusted odds ratio (aOR), 6.63; 95% CI 1.44-35.20] and metastatic infection (aOR, 17.52; 95% CI 3.69-96.93) were independent risk factors for endophthalmitis. Endophthalmitis was not associated with 30-day mortality. Endophthalmitis is rare in Asian patients with K. pneumoniae bacteremia. Targeted ophthalmologic examination in those with cryptogenic liver abscess, metastatic infection, or ocular symptoms may be more appropriate than routine examination of all patients.

Abstract
Purpose: To describe the characteristics of Klebsiella pneumoniae endogenous endophthalmitis (KEE) encountered during the COVID-19 pandemic. Methods: This retrospective consecutive case series evaluated eyes that presented with KEE between March 2020 and July 2022. Results: Seven eyes of 5 patients developed KEE. Between January 2020 and July 2022, KEE was observed in 42% of consecutive EE cases compared with 7.8% during the preceding 13 years. COVID-19 was positive in 4 of 5 patients before they developed KEE. Only 1 patient presented with a VA better than hand motions (20/400). All eyes were treated with urgent vitrectomy and intravitreal and systemic antibiotics. No improvement in vision occurred in any patient; VA remained light perception to no light perception in 60% of eyes. Conclusions: The visual prognosis in KEE is extremely poor. The presence of a preceding COVID-19 infection in 80% of patients may signal a new risk factor for KEE. Patients with a hypervirulent Klebsiella syndrome should be routinely screened for EE.

Chen Y, Gong Y, Song B, Du Y, Cai K. Pyogenic liver abscess complicated with endogenous endophthalmitis caused by Klebsiella pneumoniae: A case report and Literature Review. Immun Inflamm Dis 2023; 11:e943. [PMID: 37506152 PMCID: PMC10373569 DOI: 10.1002/iid3.943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 06/08/2023] [Accepted: 07/06/2023] [Indexed: 07/30/2023] Open
Abstract
OBJECTIVE Pyogenic liver abscess (PLA) is a common surgical infectious disease caused by various pathogens. Klebsiella pneumoniae is a relatively recent cause, often affecting patients with low immunity. Endogenous endophthalmitis (EE), a rare and serious complication of PLA, may appear with eye symptoms before PLA. By reviewing a case of Klebsiella pneumoniae-induced PLA complicated with EE, we want to summarize the information about the characteristics, causes, and complications of PLA based on the literature review. METHODS This case report describes a 37-year-old male who had fever high to 39°C for 10 days experienced blurred vision followed by nonlight perception vision. He reported a history of diabetes irregularly taking oral medications and insulin therapy. Imaging examination found a large low-density area in the right lobe of the liver with an unclear border and vague surrounding fat gap. The blood culture was not positive. The culture of the drainage fluid from the liver puncture showed Klebsiella pneumonia. Blood and liver puncture drainage fluid were sent for microbial high-throughput gene detection with next-generation sequencing technology (NGS), which confirmed the diagnosis of Klebsiella pneumoniae-induced PLA complicated with EE. RESULTS The patient's surgical incision had healed well at discharge, and he could feel light at his left eye. But the patient was lost to follow-up since the third month after discharge. CONCLUSION By reviewing this case and summarize the information about the characteristics, causes, and complications of PLA based on the literature review, we concluded that it is necessary to promptly perform liver puncture drainage and empirically use antibiotics for patients with PLA, especially those with poor glycemic control, to avoid serious complications such as EE.

Abstract
PURPOSE OF REVIEW This review provides a framework for understanding inflammatory eye disease diagnosis, differential diagnosis, and management for rheumatologists. Uveitis, scleritis, episcleritis, peripheral ulcerative keratitis, and orbital inflammation are all discussed. The goal is to facilitate the development of approaches to inflammatory eye diseases that will help rheumatologists co-manage these patients with eye care providers specializing in ocular inflammation. RECENT FINDINGS In recent years, studies have aimed to advance biologic treatments and define standard-of-care therapy. Inflammatory eye diseases are highly heterogeneous and often rare, which poses significant challenges to their research and the interpretation of existing data. To date, glucocorticoids, mycophenolate, methotrexate, and TNF inhibitors remain the mainstay of treatment options for many of these diseases. SUMMARY Patients with inflammatory eye diseases require multidisciplinary care for best outcomes, frequently including rheumatologists. Understanding the differentials, diagnostics, and treatment are essential to preserving vision in these patients. The diverse nature of the disease processes within this field requires focusing on specific disease phenotypes and endotypes in research and clinical practice.

Abstract
BACKGROUND Klebsiella pneumoniae is a common species in the gut of mammals and is widely distributed in the environment. However, the environmental source of hvKp that precedes gut colonization is unclear, but once that it reaches the gut there is a possible generalized spread y fecal-oral transmission especially in endemic areas. Liver abscess might develop when the bacteria, using its virulence factors, cross the intestinal barrier and invade the liver by the portal circulation. This syndrome, prevalent mostly in Asian countries, is increasingly reported in Western Countries and leaves open questions about the source of infection. CASE Here we describe for the first time in Italy, a case of pyogenic liver abscess caused by a hypervirulent Klebsiella pneumoniae (HvKp) complicated by endophthalmitis and other metastatic infections in lung and prostate in an immunocompetent Chinese healthy individual with no recent travel in Asia. CONCLUSION This case underlines the need for increased awareness of hypervirulent K. pneumoniae, even in settings where it occurs infrequently and where there are not evident epidemiological links.

Gram-Negative Endogenous Endophthalmitis: A Systematic Review. Microorganisms 2022; 11:microorganisms11010080. [PMID: 36677371 PMCID: PMC9860988 DOI: 10.3390/microorganisms11010080] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 12/20/2022] [Accepted: 12/24/2022] [Indexed: 12/29/2022] Open
Abstract
Background: Gram-negative bacteria are causative agents of endogenous endophthalmitis (EBE). We aim to systematically review the current literature to assess the aetiologies, risk factors, and early ocular lesions in cases of Gram-negative EBE. Methods: All peer-reviewed articles between January 2002 and August 2022 regarding Gram-negative EBE were included. We conducted a literature search on PubMed and Cochrane Controlled Trials. Results: A total of 115 studies and 591 patients were included, prevalently Asian (98; 81.7%) and male (302; 62.9%). The most common comorbidity was diabetes (231; 55%). The main aetiologies were Klebsiella pneumoniae (510; 66.1%), Pseudomonas aeruginosa (111; 14.4%), and Escherichia coli (60; 7.8%). Liver abscesses (266; 54.5%) were the predominant source of infection. The most frequent ocular lesions were vitreal opacity (134; 49.6%) and hypopyon (95; 35.2%). Ceftriaxone (76; 30.9%), fluoroquinolones (14; 14.4%), and ceftazidime (213; 78.0%) were the most widely used as systemic, topical, and intravitreal anti-Gram-negative agents, respectively. The most reported surgical approaches were vitrectomy (130; 24.1%) and evisceration/exenteration (60; 11.1%). Frequently, visual acuity at discharge was no light perception (301; 55.2%). Conclusions: Gram-negative EBEs are associated with poor outcomes. Our systematic review is mainly based on case reports and case series with significant heterogeneity. The main strength is the large sample spanning over 20 years. Our findings underscore the importance of considering ocular involvement in Gram-negative infections.

Abstract
Percutaneous catheter drainage is the first-line treatment for pyogenic liver abscess (PLA). Some patients need hepatectomy because of underling hepatobiliary pathology or unresponsiveness to nonoperative treatment, the traditional method is open hepatectomy (OH). Laparoscopic hepatectomy (LH) for PLA is rarely reported. The purpose of this study is to describe our experience of LH for treating PLA and to compare LH with OH. The medical records of patients who underwent LH for treating PLA were retrospectively analyzed, and the results were compared with those of patients with OH. From January 2015 to December 2021, 61 patients with PLA underwent hepatectomy, and 28 patients who underwent LH (LH group) were compared with 33 patients who underwent OH (OH group). There were no significant differences in the basic data between the 2 groups. Two patients in the LH group were converted to open surgery due to hemorrhage and dense perihepatic adhesions, there was no significant difference between the 2 groups in the operation time (186.2 ± 85.6 vs. 175.9 ± 76.7 minutes, P = .239), Institut Mutualiste Montsouris classification, extent of hepatectomy and drainage tube removal time, however, the blood loss (200.0 ± 100.5 vs. 470.9 ± 120.1 mL, P = .003), numerical rating scale (5.2 ± 1.8 vs. 9.1 ± 1.6, P = .042), the time to resume oral diet (12.3 ± 6.5 vs. 24.6 ± 10.2 hours, P = .005), the ambulant time (20.2 ± 7.3 vs. 40.2 ± 10.8 hours, P = .010), incidence of postoperative complications (14.3% vs.33.3%, P = .002), comprehensive complication index (46.2 vs. 60.6, P = .013), postoperative hospital stay (8.5 ± 7.3 vs. 13.5 ± 10.2 days, P = .025) in the LH group was significantly less than that in the OH group. Wit experience laparoscopic surgeons, treating PLA by LH is safe and feasible and compares favorably with OH.

Abstract
OBJECTIVES Klebsiella pneumoniae liver abscess (KPLA) complicated with extrahepatic migratory infection (EMI) is defined as invasive KPLA. The current study aimed to develop and validate a risk prediction model for the invasiveness of KPLA. METHODS From 2010 to 2020, KPLA patients from four institutes were selected retrospectively. In the development cohort, risk factors from a logistic regression analysis were utilized to develop the prediction model. External validation was performed using an independent cohort. RESULTS A total of 382 KPLA patients comprised two separate cohorts: development cohort (institute 1, n = 286) and validation cohort (institute 2-4, n = 86). The overall incidence of EMI was 19.1% (development cohort, n = 55; validation cohort, n = 18, p > 0.05). In the development cohort, four risk factors (age ≤ 40 years, fasting blood glucose (FBG) > 7 mmol/L, no rim enhancement, and thrombophlebitis on CT), significantly associated with EMI, were incorporated into the scoring system. The area under curve (AUC) of the receiver operating characteristic curve (ROC) in the development and validation cohorts was 0.931 (95% confidence interval [CI]: 0.93-0.95) and 0.831 (95% CI: 0.86-0.91), respectively. The calibration curves fitted well. The incidence of EMI was 3.3% and 56.5% for the low- (total scores ≤ 4) and high-risk (total scores > 4) groups in the development cohort, and 3.2% and 66.7% in the validation cohort (all p < 0.001), respectively. CONCLUSIONS Age ≤ 40 years, FBG > 7 mmol/L, no rim enhancement, and thrombophlebitis were independent risk factors for EMI. This validated prediction model may aid clinicians in identifying KPLA patients at increased risk for invasiveness. KEY POINTS • Four risk factors are significantly associated with extrahepatic migratory infections (EMI): age ≤ 40 years, fasting blood glucose (FBG) > 7 mmol/L, no rim enhancement, and thrombophlebitis on CT. • Based on these risk factors, the current study developed and validated a prediction model for the invasiveness of Klebsiella pneumoniae liver abscess (KPLA). • This validated prediction model may in the help early identification of KPLA patients at increased risk for invasiveness.

Abstract
Endophthalmitis is a severe form of ocular inflammation. The source of pathogens in endogenous endophthalmitis is located inside the body, and infection spreads hematogenously. Although rare, endogenous endophthalmitis is a very serious condition, as this type of inflammation is very devastating for ocular tissues. Prognosis is very poor, and the patients are often in a serious general condition, so they require special care and an individual approach in the treatment process. Thanks to the knowledge of the risks associated with infections of individual tissues and organs as well as potential pathogens and the clinical picture, it is possible to make a correct diagnosis faster and implement the correct treatment. In the case of endogenous endophthalmitis, reaction time is absolutely crucial for prognosis. In this review, we focus primarily on the importance of the primary source of infection for the course of the disease and prognosis.

Abstract
Objective: This study aimed to reveal the prevalence and fitness of qnrS1-carrying plasmids in hypervirulent Klebsiella pneumoniae (hvKP) isolates. Materials and Methods: Two hundred ninety-nine hvKP strains carrying qnrS1 were collected and screened for resistance genes using PCR and sequencing. The location of qnrS1 and rmpA2 was identified by Southern blotting. The transferability and fitness of qnrS1-carrying plasmids were analyzed by conjugation experiments and plasmid stability assay. Result: In 299 hvKP isolates, the most frequently detected capsular serotype was K64 (81.9%, 245/299), followed by K1 (4.7%, 14/299) and K2 (3.7%, 11/299). All K64-hvKP were sequence type (ST) 11. The qnrS1 and rmpA2 gene mainly was located on the ∼70-210 kb IncFrepB and ∼170-220 kb IncFIB plasmid, respectively. QnrS1-carrying plasmids could be transferred into Escherichia coli J53. However, the plasmid was transferred at a low rate of 13.4% (40/299). The 40 donor isolates belong to 4 STs-ST11, ST700, ST592, and ST86, and none contains the CRISPR-Cas loci. CRISPR-Cas loci were mainly found in ST23 K. pneumoniae. The relative fitness (RF) of qnrS1-carrying plasmids in ST86 and ST11 (cotransfer with blaTEM-1 genes) was more than one and enhanced during cultivation, especially in ST86. However, the RF of qnrS1-carrying plasmids in ST592 and ST700 showed a high fitness cost. Whole-genome sequencing showed that the qnrS1-carrying plasmids in ST86 harbored more maintenance modules (SOS inhibitor protein psiB, parA, and parB partition systems) and insertion sequence (IS) elements (IS91, IS481-like, IS1380), indicating that the qnrS1-carrying plasmid in ST86 is more stable than the other types of qnrS1-carrying plasmids. Conclusion: QnrS1-carrying IncFrepB plasmids were highly prevalent and show polymorphism in hvKP strains. The qnrS1-carrying IncFrepB plasmid in ST86 hvKP should be highlighted due to its remarkable adaptability advantages.

Abstract
BACKGROUND/AIMS Although the epidemiology of pyogenic liver abscess (PLA) continues to change, only a few population-based studies have been conducted in Korea. This study investigated the epidemiology and clinical outcomes of PLA patients during a period of 10 years. METHODS We analysed the Health Insurance Review and Assessment Service data between 2007 and 2017. The data included annual incidence rates, demographic data, underlying diseases, complications and mortality of PLA patients. RESULTS The annual incidence of PLA for all age groups was 10.9 per 100 000 population. The incidence was gradually increased from 5.7 per 100 000 in 2007 to 14.4 per 100 000 in 2017. In patients with liver abscess, the prevalence of diabetes and malignancy were 37.24% and 26.5% respectively. Metastatic infection was reported in 1.74% of the patients, and endophthalmitis was most common. The mean in-hospital mortality was 9.6%, and there was no significant difference in mortality by year during the observation period. Mortality increased with age and was greatly affected by the underlying diseases, especially cancer. Based on the multivariate analysis results, the mortality of PLA patients was associated with older age, female sex, diabetes, malignancy and chronic kidney disease. CONCLUSION The PLA incidence is rapidly increasing in Korea, especially in people with comorbidities. In addition, the causes and risk factors of PLA infections are changing and thus further research on epidemiology, different diagnosis and management approaches is required.

Abstract
We describe a case of endogenous endophthalmitis caused by sequence type 66-K2 hypervirulent Klebsiella pneumoniae in a diabetic patient with no travel history outside the United States. Genomic analysis showed the pathogen has remained highly conserved, retaining >98% genetic similarity to the original strain described in Indonesia in 1935.
