Abstract
BACKGROUND Pyelonephritis is a common infection at any age. Urine neutrophil gelatinase-associated lipocalin (NGAL), a novel biomarker of acute renal failure, is related to pyelonephritis in pediatric patients, although the significance of this urine biomarker in adult patients are not clear. We investigated the relationship between urine NGAL of pyelonephritis and non-pyelonephritis. PATIENTS AND METHODS We prospectively enrolled adult patients who were hospitalized due to pyelonephritis or non-pyelonephritis. Pyelonephritis was diagnosed in patients with fever and bacteriuria, with no any other infection focuses. Non-pyelonephritis was diagnosed in patients who had fever and another infection focus without bacteriuria. Urine samples were collected on days 0, 3 and 7. Urine NGAL levels were measured by ELISA. RESULTS There were 35 patients in the pyelonephritis group and 19 patients in the non-pyelonephritis group. Urine NGAL level were significantly higher in the pyelonephritis group than the non-pyelonephritis group on day 0 (median 302 ng/mL vs 25 ng/mL, p = 0.006). The area under the receiver operating characteristic curve of NGAL was 0.78 (p = 0.006). Urine NGAL level had a specificity of 66.7% and sensitivity of 87.0% at the cut-off level of 250 ng/mL for diagnosing pyelonephritis. CONCLUSIONS Urine NGAL level at the diagnosis of infection are elevated in adult patients with pyelonephritis, but not in those with non-pyelonephritis. Urine NGAL might be a supportive biomarker for the diagnosis of pyelonephritis.

Prevalence of and factors associated with atypical presentation in bacteremic urinary tract infection. Sci Rep 2022; 12:5197. [PMID: 35338229 PMCID: PMC8956699 DOI: 10.1038/s41598-022-09222-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 03/16/2022] [Indexed: 12/17/2022] Open
Abstract
A delay in the diagnosis of urinary tract infection (UTI) is not uncommon. Atypical presentation is often cited as one of the causes of diagnostic delays. However, few studies have investigated the prevalence of atypical presentation and determined factors associated with atypical presentation at initial contact among patients with UTI. Therefore, a retrospective and prospective cohort study using chart review was conducted in two acute care hospitals. We included 285 consecutive patients hospitalized for bacteremic UTI. The primary outcome was atypical presentation, defined as the absence of any urinary tract symptom or sign at initial contact. Of all patients, the median age was 82 years, 186 (65.3%) were women, and 53 (18.6%) had dementia. Urinary tract symptoms and signs were absent at initial contact in 144 patients (50.5%; 95% CI 44.7–56.4%). The multivariable analysis revealed that older age, male sex, dementia, and early visit from symptom onset were significantly associated with an increased risk of atypical presentation. Patients with atypical presentation were less likely to receive a correct diagnosis at initial contact than patients with urinary tract symptoms and signs (OR 0.30; 95% CI 0.17–0.51). Atypical presentation in patients with bacteremic UTI is common and negatively affects the correct diagnosis of UTI.

Abstract
BACKGROUND In older adults, the diagnosis of acute pyelonephritis is challenging because of non-specific symptoms and false-positive urine test results. Few studies have investigated the diagnostic performance of computed tomography (CT) signs. PURPOSE To evaluate the diagnostic performance of CT signs for acute pyelonephritis in older patients suspected of infection with unknown focus. MATERIAL AND METHODS This cross-sectional study was conducted between 2015 and 2018. Patients aged ≥65 years who underwent blood cultures, urine culture, and non-contrast or contrast-enhanced CT on admission were included. Cases with clinically presumable infection focus before CT were excluded. Two radiologists blinded to clinical information independently reviewed five CT signs: perirenal fat stranding; pelvicalyceal wall thickening and enhancement; renal enlargement; thickening of Gerota's fascia; and area(s) of decreased attenuation. The final diagnoses were made by a clinical expert panel. RESULTS Among 473 eligible patients, 61 were diagnosed with acute pyelonephritis. When the laterality of findings between the left and right kidneys were considered, the positive and negative likelihood ratios of perirenal fat stranding were 4.0 (95% confidence interval [CI] = 2.3-7.0) and 0.8 (95% CI = 0.7-0.9) in non-contrast CT, respectively. The other signs in non-contrast CT showed similar diagnostic performance with positive and negative likelihood ratios of 3.5-11.3 and 0.8-0.9, respectively. CONCLUSION CT signs can help physicians diagnose acute pyelonephritis in older patients suspected of infection with unknown focus.

Abstract
To investigate the differences in clinical and microbiological features in men hospitalized with community-acquired (CA) and healthcare-associated (HA) nonobstructive acute pyelonephritis (APN), as well as the predictive factors associated with bacteremia.Men discharged from urological centers with nonobstructive APN were identified using an electronic medical records system. We compared the clinical and microbiological data between subjects with CA-APN and HA-APN.Of the 245 men with nonobstructive APN, 175 had CA-APN, and 70 had HA-APN. The HA group was significantly older, had a longer hospital stay, and had more underlying diseases, bacteremia, and intensive care unit admissions than the CA group. The most commonly cultured microorganism was Escherichia coli. The susceptibility of the cultured bacteria to fluoroquinolone was 68.7% in the CA group and 45.3% in the HA group (P = .005). The proportion of extended-spectrum beta-lactamase-producing bacteria was 22.7% for CA and 53.5% for HA (P < .001). The sensitivity to piperacillin/tazobactam was 94.9% for CA and 90.0% for HA, and the sensitivity to amikacin was more than 95% for both groups. The multivariate analysis revealed that an age ≥65 years and chronic liver disease were independent predictive factors for bacteremia.The incidence of antibiotic resistance and bacteremia was higher in the HA group than in the CA group. However, resistance to fluoroquinolone and the presence of extended-spectrum beta-lactamase-producing bacteria were high in both groups. Piperacillin/tazobactam and amikacin may be suitable treatment options in men with nonobstructive APN.

Abstract
Introduction The incidence of acute pyelonephritis (APN) in the diabetic population is comparatively higher and tends to be more complicated, with serious outcomes. Although complicated pyelonephritis (PN) needs hospital admission and intravenous antibiotics, the magnitude of hospital stay due to comorbidities is limited. This study's aim was to assess the impact of diabetes mellitus on length of hospital stay among patients with PN. Methods We did a retrospective data review of 520 randomly selected hospitalized patients of PN from March 2015 to December 2019 from a tertiary care center. Electronic medical records were used for identifying medical conditions through ICD-10 coding. Length of stay (LOS) was categorized as < five days and ≥ five days. Chi‐squared tests were used to compare categorical parameters. Logistic regression models were used for multivariate analyses. Results The study included 520 patients with PN; 194 (37.3 %) men and 326 (62.7%) women. Overall, there were 353 (67.8 %) and 167 (32.1 %) patients with LOS < five and ≥ five days respectively. Most of the patients had lower urinary tract symptoms (90%); among them, the majority (92%) were discharged within five days. Likewise, half of the patients had diabetes (51.2); among them, 53% were discharged after five days. Older age (OR:1.7, 95%CI: 1.1 - 2.6), upper urinary tract symptoms (OR:1.6, 95%CI: 1.1 - 2.4), lower urinary tract symptoms (OR:1.9, 95%CI: 1.1 - 3.5), creatinine greater than 1.5 mg/dl (OR:1.6, 95% CI: 1.1 - 2.4) was positively associated with LOS ≥ 5 days after adjusting for other covariates. Diabetes mellitus was not found to be associated with LOS ≥ 5 days (OR: 0.9, 95%CI: 0.8 - 1.5). Conclusion In patients with acute PN, diabetes mellitus is not independently associated with prolonged hospital stay beyond five days.

Abstract
Background The purpose of this study was to compare clinical characteristics and outcomes in individuals of different age groups with urinary tract infection (UTI), and to identify the relationships among advanced age and uroseptic shock. Methods This retrospective study compared clinical characteristics and outcomes in patients in different age groups with UTI and identified relationships between advanced age and uroseptic shock among hospitalized patients with UTI in an acute hospital care setting from January 2006 to October 2018. Patients were divided into young (age below 65 years), old (65–80 years), and very old (above 80 years) groups. Results Of 1,043 participants, 269 (25.8%) were very old and 200 (19.2%) developed uroseptic shock. Very old age [odds ratio (OR) 1.99, 95% confidence interval (CI): 1.25–3.19, P=0.004], male (OR 1.54, 95% CI: 1.07–2.24, P=0.022), presented flank pain (OR 1.54, 95% CI: 1.05–2.24, P=0.025), congestive heart failure (CHF) (OR 2.54, 95% CI: 1.27–5.06, P=0.008), acute kidney injury (AKI) (OR 4.19, 95% CI: 2.78–6.30, P<0.001), bacteremia (OR 1.78, 95% CI: 1.25–2.53, P=0.001), and multiple drug-resistant (MDR) bacteria (OR 1.43, 95% CI: 1.02–2.00, P=0.039) were associated with an increased risk of uroseptic shock in patients with UTI. In very old patients with UTI, bacteremia (OR 2.54, 95% CI: 1.38–4.69, P=0.003) and AKI (OR 4.37, 95% CI: 2.15–8.90, P<0.001) were independently associated with uroseptic shock. Conclusions Very old patients with UTI had a higher risk of developing uroseptic shock than younger patients. Bacteremia was an independent risk factor for uroseptic shock in very old patients with UTI.

Abstract
Background Urinary tract infections (UTI) are among the most frequent bacterial infections in older adults. The aim of the study was to analyse the existence of differences in clinical features, microbiological data and risk of infection by multidrug-resistant organisms (MDRO) between older and non-older men with febrile UTI (FUTI). Methods This was an ambispective observational study involving older males with a FUTI attended in the Emergency Department. Variables collected included age, comorbidity, diagnostic of healthcare-associated (HCA)-FUTI, clinical manifestations, hospitalization, mortality, and microbiological data. Results Five hundred fifty-two males with a FUTI, 329 (59.6%) of whom were older adults, were included. Older males had a higher frequency of HCA-FUTI (p < 0.001), increased Charlson scores (p < 0.001), had received previous antimicrobial treatment more frequently (p < 0.001) and had less lower urinary tract symptoms (p < 0.001). Older patients showed a lower frequency of FUTI caused by E. coli (p < 0.001) and a higher rate of those due to Enterobacter spp. (p = 0.003) and P. aeruginosa (p = 0.033). Resistance rates to cefuroxime (p = 0.038), gentamicin (p = 0.043), and fluoroquinolones (p < 0.001) in E. coli isolates and the prevalence of extended-spectrum beta-lactamase and AmpC producing E. coli and Klebsiella spp. strains (p = 0.041) and MDRO (p < 0.001) were increased in older males. Inadequate empirical antimicrobial treatment (p = 0.004), frequency of hospitalization (p < 0.001), and all cause in-hospital mortality (p = 0.007) were higher among older patients. In the multivariate analysis, being admitted from an long term care facility (OR 2.4; 95% CI: 1.06–5.9), having a urinary tract abnormality (OR 2.2; 95% CI: 1.2–3.8) and previous antimicrobial treatment (OR 3.2; 95% CI: 1.9–5.4) were associated to FUTI caused by MDRO. Conclusions Older male adults with a FUTI have different clinical characteristics, present specific microbiological features, and antimicrobial resistance rates. In the multivariate analysis being an older male was not associated with an increased risk of FUTI caused by MDRO.

Abstract
PURPOSE OF REVIEW Complicated infections of the urinary tract (UTI) including pyelonephritis and urosepsis are also called febrile UTI. This review describes insights from the literature on this topic since July 2014. RECENT FINDINGS Recent studies regarding risk factors and consequences of febrile UTI confirmed existing knowledge. It remains difficult to obtain insight into the epidemiology of febrile UTI because urine and blood cultures are frequently missing. The relationship between host and virulence factors of Escherichia coli was further explored showing that less virulent strains can cause infection in immunocompromised patients. In contrast to obstructive uropathy, diabetes, and being older, neutropenia was not a risk factor for lower UTI or urosepsis. A randomized controlled trial revealed that ceftolozane-tazobactam was marginally superior to levofloxacin as treatment for complicated UTI. Case series supported the notion that xanthogranulomatous and emphysematous pyelonephritis are more common in diabetic patients and that drainage or surgery is often required. SUMMARY Neutropenia was not a risk factor for lower UTI or urosepsis. When local resistance percentages to the frequently prescribed fluoroquinolones are high, the combination of ceftolozane-tazobactam may be an alternative as treatment for complicated UTI. Xanthogranulomatous and emphysematous pyelonephritis need to be considered in diabetic patients presenting with UTI symptoms.
