Infections by OXA-48-like-producing Klebsiella pneumoniae non-co-producing extended-spectrum beta-lactamase: Can they be successfully treated with cephalosporins?
OXA-48 is an Ambler class D β-lactamase that hydrolyses penicillin and imipenem but has poor hydrolytic activity against cephalosporins. However, very few clinical experiences of treating extended-spectrum β-lactamase (ESBL)-negative OXA-48 producers with cephalosporins have been published.. The aim of this study was to report clinical experience of infections due to ESBL-negative OXA-48-producing Klebsiella pneumoniae (K. pneumoniae) treated with cephalosporins.. A retrospective study was conducted at Vall d'Hebron University Hospital, in Barcelona (Spain). It reviewed all microbiological isolates of OXA-48-producers that did not co-produce ESBL from May 2014 to May 2017, and included only clinical strains of patients treated with a cephalosporin for ≥72h.. From the 75 isolations of OXA-48 producers, there were 17 isolations of ESBL-negative OXA-48-producing K. pneumoniae. Three patients were treated with cephalosporins with successful outcomes: a pneumonia in a neutropenic patient treated with cefepime and amikacin; an acute focal nephritis of a renal graft treated with ceftriaxone; and an intrabdominal post-surgical infection treated with cefepime in combination with tigecycline at the beginning, and ciprofloxacin afterwards.. Cephalosporins could be an alternative treatment in selected patients with ESBL-negative OXA-48-producing K. pneumoniae infections, especially to avoid carbapenem use. However, it remains unknown if they should be given in combination.

Acute focal bacterial nephritis in a cohort of hospitalized adult patients with acute pyelonephritis. Assessment of risk factors and a predictive model.
Acute focal bacterial nephritis (AFBN) is a complicated form of acute pyelonephritis (APN) characterized by single or multiple areas of localised infection in the kidney without liquefaction or abscess. Studies investigating AFBN in adults are scarce.. The present study was aimed at evaluating the prevalence, associated factors, and presence of atypical clinical and radiological manifestations in adult AFBN patients. Also, we developed a clinical prediction model to evaluate the probability of AFBN in patients with APN.. The clinical records of 377 patients (mean age 54years, 74.0% females) admitted to a hospital over a 5-year period with APN were reviewed.. A total of 57 cases of AFBN were radiologically identified (prevalence, 15.1%). Patients with AFBN were younger and displayed atypical manifestations more frequently than patients without AFBN; these included both clinical and radiological (pleural effusion, gallbladder wall thickening, fluid around the gallbladder, perirenal fluid, and ascites) manifestations. Patients with AFBN showed lower systolic blood pressure and needed more days of therapy to become afebrile, longer total duration of antibiotic therapy, and longer hospital stay than patients without AFBN. Contraceptive use was more frequent in patients with AFBN. A model based on five clinical variables showed good discrimination performance for the diagnosis of AFBN (Area under the curve, 0.77 (95% CI, 0.69-0.89)).. Patients with AFBN frequently present with atypical clinical and radiological manifestations. Clinical presentation by means of a predictive model may predict the presence of AFBN. Patients with AFBN need more intensive therapy, which is followed by a favourable outcome.

Focal bacterial nephritis without pyuria in a boy presenting with high urinary β2-MG and NAG levels.
Acute focal bacterial nephritis (AFBN) is a localized bacterial infection of the kidney presenting as an inflammatory mass without frank abscess formation. We report a case of acute focal bacterial nephritis without pyuria in a five-month-old boy presenting with high urinary β2-microglobulin (β2-MG) and N-Acetyl-β-(D)-Glucosaminidase (NAG) levels. The infant initially presented with high-grade fever, and plain computed tomography (CT) showed a nearly isodense mass, and contrast-enhanced abdominal CT showed a wedge-shaped hypodense lesion. Enterococcus was detected in the subsequent urine culture. A diagnosis of AFBN was made on the basis of his high inflammatory reaction, contrast-enhanced abdominal CT findings and high urinary β2-MG and NAG levels. He was treated with Ceftriaxone and subsequent improvement in inflammatory reaction and contrast-enhanced CT findings were observed. Voiding cystourethrogram (VCUG) showed a grade V right VUR. This case suggests that urinary β2-MG and NAG levels may be useful additional markers for the diagnosis of AFBN without pyuria.
