ABSTRACT
A cost-minimization analysis was conducted for Klebsiella pneumoniae liver abscess (KLA) patients enrolled in a randomized controlled trial which found oral ciprofloxacin to be non-inferior to intravenous (IV) ceftriaxone in terms of clinical outcomes. Healthcare service utilization and cost data were obtained from medical records and estimated from self-reported patient surveys in a non-inferiority trial of oral ciprofloxacin versus IV ceftriaxone administered to 152 hospitalized adults with KLA in Singapore between November 2013 and October 2017. Total costs were evaluated by category and payer, and compared between oral and IV antibiotic groups over the trial period of 12 weeks. Among the subset of 139 patients for whom cost data were collected, average total cost over 12 weeks was $16,378 (95% CI, $14,620-$18,136) for the oral ciprofloxacin group and $20,569 (95% CI, $18,296-$22,842) for the IV ceftriaxone group, largely driven by lower average outpatient costs, as the average number of outpatient visits was halved for the oral ciprofloxacin group. There were no other statistically significant differences, either in inpatient costs or in other informal healthcare costs. Oral ciprofloxacin is less costly than IV ceftriaxone in the treatment of Klebsiella liver abscess, largely driven by reduced outpatient service costs.Trial registration: ClinicalTrials.gov Identifier NCT01723150 (7/11/2012).

OBJECTIVES: The Enterobacter cloacae complex is responsible for a variety of infections in hospitalized patients and is resistant to ß-lactam antibiotics owing to the expression of AmpC ß-lactamase. We report emerging resistance in Enterobacter roggenkampii exposed to ceftriaxone and explore the mechanism underlying mutations responsible for this resistance. METHODS: Three strains were derived from different samples from one patient (blood and liver abscess fluid). Antimicrobial susceptibility was evaluated by standard broth microdilution, while ampC expression was determined via RT-PCR. Genetic relatedness was evaluated via pulsed-field gel electrophoresis (PFGE). Species identification and comparative genome analysis were performed via genome sequencing. Mutation rate testing and selection of AmpC-derepressed mutants were conducted to explore the mutation mechanism. RESULTS: E. roggenkampii F1247 was susceptible to third-generation cephalosporins (3GCs); F95 and F1057, found in blood sample on day 11 and liver abscess drainage fluid on day 25, were resistant. ampC expression was 341- and 642-fold higher in F95 and F1057, respectively, than in F1247. Three isolates were the same PFGE and sequence types (ST1778) and were highly homologous (2 and 4 core genome single nucleotide polymorphism differences). Compared to F1247, F95 possessed a 575 bp deletion, including 537 bp of ampD, whereas F1057 harbored only one amino acid mutation (Leu140Pro in ampD). The mutation rates from F1247 exposure to cefotaxime, ceftazidime, ceftriaxone, piperacillin-tazobactam, and cefepime were (1.90 ± 0.21) × 10-8, (3.18 ± 0.43) × 10-8, (2.00 ± 0.20) × 10-8, (2.92 ± 0.29) × 10-9, and zero, respectively. In vitro-selected mutations responsible for resistance were identified in ampD, ampR, and dacB. CONCLUSIONS: E. roggenkampii may develop resistance in vivo and in vitro upon exposure to 3GCs and to a lesser extent to piperacillin-tazobactam. 3GCs should not be used as a monotherapy for E. roggenkampii infections. Therapy using cefepime or carbapenems may be preferred to piperacillin-tazobactam in the treatment of E. roggenkampii, especially if source control is difficult.

Acinetobacter baumannii is naturally resistant to several classes of antibiotics and readily develops further resistance mechanisms under antibiotic pressure. For patients infected with extremely drug-resistant organisms, effective antibiotic treatments are intravenous and often require inpatient hospitalization for monitoring and dose adjustment. A 31-year-old active duty service member, stationed in Southeast Asia, sustained thermal burns from an electrical arc injury to over 40% of his total body surface area. His hospital course was complicated by multiple extensively drug resistant (XDR) A. baumanii infections including bacteremia and hepatic abscesses. To facilitate discharge to his family, his hepatic abscesses were treated successfully as an outpatient with several weeks of parenteral colistin monotherapy. With regular renal function testing, his dosages were held and/or adjusted to compensate for acute kidney injuries, and he was successfully cleared of his infection. Up to 50% of A. baumannii isolates in American hospitals, including major DOD facilities, are carbapenem resistant. As a result, historically last-line therapies, such as polymyxins, are increasingly used as treatment. New dosing guidance is emphasized to minimize renal toxicities. This case demonstrates the ability to administer parenteral colistin as an outpatient under close supervision.

Multi drug resistant (MDR) Pseudomonas aeruginosa and Extended- Spectrum-lactamase (ESBL) Enterobacteriaceae are becoming an increasing difficult clinical problem. Immediate resistance to some of the new antimicrobials such as ceftolozane/tazobactam is unusual and is due to a variety of mechanisms such as hyper-production of inactivating enzymes and gene mutation. In addition, previous antimicrobial administration is a well-recognized risk factor to develop resistance. We present a patient with a liver abscess where the organism was resistant to ceftolozane/tazobactam resulting in a poor clinical outcome.

Background: Chronic granulomatous disease (CGD) is a rare genetic disorder causing recurrent infections. More than one-quarter of patients develop hepatic abscesses and liver dysfunction. Recent reports suggest that disease-modifying treatment with corticosteroids is effective for these abscesses. Comparison of corticosteroid therapy to traditional invasive treatments has not been performed. Methods: Records of 268 patients with CGD treated at the National Institutes of Health from 1980 to 2014 were reviewed. Patients with liver involvement and complete records were included. We recorded residual reactive oxygen intermediate (ROI) production by neutrophils, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase germline mutation status, laboratory values, imaging characteristics, time to repeat hepatic interventions, and overall survival among 3 treatment cohorts: open liver surgery (OS), percutaneous liver-directed interventional radiology therapy (IR), and high-dose corticosteroid management (CM). Results: Eighty-eight of 268 patients with CGD suffered liver involvement. Twenty-six patients with a median follow-up of 15.5 years (8.5-32.9 years of follow-up) had complete records and underwent 100 standard interventions (42 IR and 58 OS). Eight patients received a treatment with high-dose corticosteroids only. There were no differences in NADPH genotype, size, or number of abscesses between patients treated with OS, IR, or CM. Time to repeat intervention was extended in OS compared with IR (18.8 vs 9.5 months, P = .04) and further increased in CM alone (median time to recurrence not met). Impaired macrophage and neutrophil function measured by ROI production correlated with shorter time to repeat intervention (r = 0.6, P = .0019). Conclusions: Treatment of CGD-associated liver abscesses with corticosteroids was associated with fewer subsequent hepatic interventions and improved outcome compared to invasive treatments.

BACKGROUND: Melioidosis caused by Burkholderia pseudomellei is an infection with protean clinical manifestations. Guillain-Barré syndrome [GBS] associated with melioidosis is very rare. CASE PRESENTATION: A 42-year-old woman with diabetes presented with abdominal pain, vomiting and intermittent fever for one month. Six months before presentation she had recurrent skin abscesses. Three months before presentation she had multiple liver abscesses which were aspirated in a local hospital. The aspirate grew "coliforms" resistant to gentamicin and sensitive to ceftazidime. On presentation she had high fever and tender hepatomegaly. Ultra Sound Scan of abdomen showed multiple liver and splenic abscesses. Based on the suggestive history and sensitivity pattern of the previous growth melioidosis was suspected and high dose meropenem was started. Antibodies to melioidin were raised at a titre of 1:10240. The growth from the aspirate of liver abscess was confirmed as Burkholderia pseudomellei by polymerase chain reaction [PCR]. After a week of treatment, patient developed bilateral lower limb weakness. Deep tendon reflexes were absent. There was no sensory loss or bladder/bowel involvement. Analysis of the cerebro-spinal fluid showed elevated proteins with no cells. There was severe peripheral neuropathy with axonal degeneration. A diagnosis of GBS was made and she was treated with plasmapharesis with marked improvement of neurological deficit. Continuation of intravenous antibiotics lead to further clinical improvement with normalization of inflammatory markers and resolution of liver and splenic abscess. Eradication therapy with oral co-trimoxazole and co-amoxyclav was started on the seventh week. Patient was discharged to outpatient clinic with a plan to continue combination of oral antibiotics for 12 weeks. At the end of 12 weeks she was well with complete neurological resolution and no evidence of a relapse. CONCLUSIONS: Guillaine Barre syndrome is a rare complication of melioidosis and should be suspected in a patient with melioidosis who develop lower limb weakness. Plasmapharesis can be successfully used to treat GBS associated with active melioidosis.

Caso clínico: Paciente diabético que desarrolla una uveítis unilateral con un foco de coriorretinitis en el ojo derecho asociada a fiebre y disminución de la visión. Sospechándose una endoftalmitis endógena se realizaron pruebas complementarias encontrándose abscesos hepáticos con biopsia positiva para Klebsiella. La afectación ocular se fue resolviendo gracias a antibioticoterapia intravenosa y al drenaje percutáneo de los abscesos. Conclusión: La endoftalmitis endógena por Klebsiella es un hallazgo poco frecuente con consecuencias graves. Un diagnóstico y un tratamiento antibioticoterápico tempranos pueden mejorar el cuadro aunque la visión resultante suele ser pobre(AU)
Case report: A diabetic patient who developed a unilateral uveitis with a chorioretinitis patch in his right eye associated with decreased visual acuity and fever. Endogenous endophthalmitis was suspected and complementary tests were performed, finding hepatic abscesses with Klebsiella isolation in the biopsy. The ocular disorder slowly improved with intravenous therapy and guided percutaneous liver drainage. Conclusion: Endogenous Klebsiella endophthalmitis is an uncommon condition with severe complications. An early diagnosis and aggressive antibiotic therapy can ameliorate the final course but the visual outcome still remains poor(AU)

HISTORY AND ADMISSION FINDINGS: A 71-year-old man was admitted to the emergency unit of another hospital with a mild gastroenteritis and high fever. On admission g-GT and C-reactive protein (CRP) levels were markedly elevated. Under nonspecific antibiotic therapy with ampicillin/sulbactam the fever persisted and for the first time, on day 5, the patient complained of right-sided abdominal pain. An increase in the laboratory values indicated cholestasis. After changing the antibiotics to ceftriaxon and metronidazole, acute cholangitis being suspected, the fever subsided immediately and the CRP level decreased. The patient was discharged after seven days of antibiotic treatment. But he was once more admitted after four weeks to another hospital because of severely reduced general condition and mild fever. He was transferred to our unit after two weeks. INVESTIGATIONS AND DIAGNOSIS: The test values indicated cholestasis and CRP was markedly elevated, while aminotransferase activity was slightly increased and normocytic normochromic anemia developed. Viral hepatitis, autoimmune and metabolic liver diseases, toxic liver damage, extrahepatic cholestasis and an endocarditis were excluded. Bile was aspirated by endoscopic retrograde cholangiopancreatography and added to blood culture bottles. Salmonella enterica serovar choleraesuis var. Kunzendorf was isolated. TREATMENT AND FURTHER COURSE: The patient was treated with ciprofloxacin, 2 x 250 mg by mouth for a total of five weeks. After 17 days of treatment no Salmonella bacteria were grown from a newly aspirated bile sample and the patient became free of fever. CONCLUSION: Salmonella infections do not always present as gastroenteritis. Bacteremia should be considered in the differential diagnosis of such infections. If cholangitis persists, the aspiration of bile for microbiological tests can be a rational diagnostic step and facilitates treatment. Prolonged administration of antibiotics is necessary to avoid relapse. and follow-up is very important when treatment is finished.

OBJECTIVES: The aim of the study was to characterize the genetic basis of beta-lactam resistance developed in clinical isolates of Klebsiella pneumoniae after exposure to cefuroxime. METHODS: Clinical features of two episodes of liver abscess caused by K. pneumoniae in a diabetic patient were reported. Four isolates (KP(1)/KP(2) and KP(3)/KP(4)) of K. pneumoniae were recovered from cultures of blood/pus in the first and second episodes, respectively. Laboratory investigation of the K. pneumoniae isolates included genotyping by PFGE, resistance gene analysis by PCR amplification and DNA sequencing, and outer membrane protein analysis by SDS-PAGE. RESULTS: KP(3) and KP(4) were recovered after a 21 day cefuroxime therapy and demonstrated identical genotypes to that of KP(1) and KP(2). However, compared with KP(1) and KP(2), emerging resistance to piperacillin, cefalotin, cefuroxime and cefoxitin was observed. The other antibiotics tested, except ampicillin, retained the same effectiveness against the four isolates, although increases (4- to 8-fold) in the MICs of cefotaxime, ceftriaxone, ceftazidime, cefepime, flomoxef and aztreonam were observed in KP(3) and KP(4). None of the isolates produced extended-spectrum beta-lactamases or plasmid-mediated AmpC beta-lactamases. Deficiency in the expression of an outer membrane protein (OmpK35) was observed in the cefuroxime-resistant isolates, KP(3) and KP(4). CONCLUSIONS: The increased resistance to cephalosporins in these clinical isolates of K. pneumoniae after exposure to cefuroxime might be related to the loss of OmpK35.

The Bi-Digital O-Ring Test has been very useful in the identification of bacterial and viral infections, as well as other etiological agents, in difficult clinical cases. Case report of a patient with multiple hepatic abscesses (pylephlebitis induced hepatic abscess is the most difficult abscess to treat), in which the etiological agent was suggested through Bi-Digital O-Ring Test with excellent clinical evolution after modification of previously ineffective multi anti-microbial treatment is presented. 45 years old, female with a history of pain at right hypochondria for 15 days, with jaundice, oscillating fever and shivering. Computerized tomography showed liver with multiples nodules in the parenchyma with additional appendicitis. An appendectomy was performed with drainage of intra abdominal abscesses. Treatment with metronidazol, ceftazidim and amicacine was performed with no improvement while the general condition of the patient was deteriorating progressively in the following 3 weeks. Bi-Digital O-Ring Test was then performed to determine the etiological agent and the drug compatibility test among effective antimicrobial agents. Based on the Bi-Digital O-Ring Test, the main etiological agent was found to be Enterobacter aerogenes. Amongst the three antibiotics that were being used, only metronidazol was effective and the other 2 was cancelled its effect. Based on Bi-Digital O-Ring Test findings two new antibiotics (cefadroxil and imipenen), were added to metronidazol and additional cilantro tablets by Hayashibara, Japan was given, and Selective Drug Uptake Enhancement Method performed, with excellent clinical, laboratory testing and tomography improvement within 10 days. Bi-Digital O-Ring Test suggested the etiological agent, and effective and mutually compatible antibiotics for treating the abscesses which resulted in a good clinical evolution, characterized by relief of fever and reduction of the hepatic abscesses in a short period and followed complete disappearance of hepatic abscess.

Bacterial flora of liver abscesses from cattle fed tylosin or no tylosin and susceptibilities of the predominant bacterial isolates to tylosin and other antimicrobial compounds were determined. Abscessed livers were collected at slaughter from cattle originating from feedlots that had fed tylosin (n = 36) or no tylosin (n = 41) for at least 2 yr, and segments of livers with one or two intact abscesses were transported to the laboratory. Abscesses were cultured for anaerobic and facultative bacteria. Fusobacterium necrophorum, either as single culture or mixed with other bacteria, was isolated from all abscesses. The incidence of subsp. necrophorum, as part of the mixed infection, was lower (P < .05) in the tylosin group than in the no-tylosin group (33 vs 61%). However, the incidence of Actinomyces pyogenes was higher (P < .01) in the tylosin group than in the no-tylosin group (53 vs 10%). Totals of 119 F. necrophorum and 21 A. pyogenes isolates were used for determinations of susceptibilities to bacitracin, oxytetracycline, chlortetracycline, lasalocid, monensin, tylosin, tilmicosin, and virginiamycin. The minimum inhibitory concentrations (MIC) of antibiotics were determined with a broth microdilution method. The mean MIC of tylosin for F. necrophorum and A. pyogenes were not different between isolates from tylosin and no-tylosin groups. We concluded that continuous feeding of tylosin did not induce resistance in F. necrophorum or A. pyogenes. Also, the higher incidence of mixed infection of F. necrophorum and A. pyogenes in liver abscesses of tylosin-fed cattle suggests a potential synergistic interaction between the two organisms in causing liver abscesses.

Clostridium septicum bacteremia is frequently associated with hematologic and colonic malignancies and neutropenia. It frequently produces 'metastatic' gangrene with excessive mortality. Standard therapy usually includes surgical debridement and antibiotics. We present a patient with metastatic breast cancer treated with high-dose chemotherapy and bone marrow transplantation. She was treated successfully with antibiotics alone despite developing Cl. septicum bacteremia and gas in hepatic metastases. The pathophysiology of this infection is reviewed.

We are reporting on a 36-year-old man with septicemia and a liver abscess due to Actinomyces sp. The infection was most probably acquired while eviscerating a deer he had shot. The possibility of an infection involving Actinomyces bovis is discussed. The liver abscess was diagnosed on the basis of non-invasive procedures. Therapy consisted of high-dose penicillin without surgical drainage of the abscess. The infection did not recur during the three-and-a-half year follow-up period. No previous reports of successful antibiotic therapy for actinomycotic liver abscess without surgical procedures are known.

The investigation of microbial flora and its sensitivity in 196 patients with the kidney abscesses of various etiology showed expediency of the use of aminoglycosides, ampicillin and lincomycin. The local use of colloid iodine promoted rapid inhibition of the microbial flora. The dynamic observations showed an increase in the number of gramnegative pathogens by the 7th--10th day of the treatment. Rational surgical intervention, the antibiotic use with control of the microbial flora sensitivity, specific chemotherapy provided a decrease in the lethality up to 6.7 per cent.
