The significance of bacteriuria in patients with end-stage renal disease (ESRD) on hemodialysis (HD) is unclear. It is not known whether treatment of asymptomatic bacteriuria is associated with lower rates of urinary tract infection or readmission. Adult patients with ESRD on HD were retrospectively evaluated to assess factors associated with the recurrence of bacteriuria and readmission. We included 68 patients in the analysis. There were 20 patients (29.4%) with urinary symptoms. All symptomatic patients received antibiotic therapy, whereas half of the asymptomatic patients received antibiotics...

BACKGROUND: Infection is a rare complication following implantation of prosthetic material into a joint. The impact of asymptomatic bacteriuria (ASB) before elective operations and the subsequent risk of prosthetic joint infection (PJI) are not well understood. AIMS: • Assess the prevalence of ASB amongst patients undergoing total arthroplasty of the hip and knee. • Determine the rates of PJI diagnosed within two years of the arthroplasty and if ASB is an independent risk factor for developing PJI...

Urinary tract infections are common in the elderly. They are a frequent reason for antibiotic prescription in nursing homes and hospitals. Doctors are confronted daily to the challenge that it is to diagnose urinary tract infections in older patients. The incidence of asymptomatic bacteriuria and the presence of unspecific symptoms and signs in this population transform guidelines for prevention and treatment into some kind of a battle. In this article we will : 1) make a reminder of the particular features of urinary tract infection in the elderly person ; 2) present the recommendations made by the experts and 3) emphasize the prevention of catheter-related urinary tract infection...

Urine culture still has to be considered as the gold standard to rule out bacteriuria and should, therefore, be obtained prior to invasive endoscopic or open urological procedures to minimize the risk of severe infectious complications.

Acute lobar nephritis (ALN) is a focal interstitial bacterial infection of the renal parenchyma. ALN is described as a midpoint between an acute pyelonephritis and renal abscess. ALN is underdiagnosed in children due to both non-specific symptoms and negative urinalysis/bacteriuria laboratory findings. The gold standard for diagnosis of ALN is CT scanning, however MRI can be considered to avoid radiation exposure. Diagnosing ALN is relevant, because it requires prolonged antibiotic treatment. Insufficient antibiotic treatment could cause renal scarring and subsequent hypertension or renal failure...

Asymptomatic bacteriuria is frequently detected in women aged up to 60 years, patients with diabetes and elderly patients. The benefit of antibiotic treatment for this condition is controversial. The objective of this Cochrane systematic review was to assess the effectiveness and safety of antibiotic treatment for asymptomatic bacteriuria in adults. A systematic review of the literature up to 24 February 2015 was performed using the Cochrane Renal Group's Specialised Register. Randomised controlled trials (RCTs) and quasirandomised controlled trials comparing antibiotics to placebo or no treatment for asymptomatic bacteriuria in adults were included...

OBJECTIVE: To investigate an association between Group B streptococci in urine culture during pregnancy and preterm delivery. METHODS: A population-based cohort consisted of all pregnant women (n = 36 097) from the catchment area of Lillebaelt Hospital, Denmark, during the period January 2002 -December 2012. The cohort of 34 285 singleton pregnancies used in this study was divided into three groups. Group I (N = 249) included women whose urine culture was positive for Group B streptococci (GBS); group II (N = 5765) included women whose urine culture was negative for GBS; and group III (N = 28 271) included women whose urine had not been cultured during pregnancy...

BACKGROUND: Pelvic organ prolapse (POP) is the herniation of pelvic organs from its anatomical confines, and it is of considerable importance to the practicing gynaecologist in middle and low income countries. It is commonly associated with, urinary tract infection (UTI), both symptomatic and asymptomatic due to anatomical and physiological changes. The aim of this study was to determine the prevalence of asymptomatic bacteriuria among women with pelvic organ prolapse, to know the organisms commonly implicated and the sensitivity pattern...

We present a case of pyeloduodenal fistula in an 89-year-old woman with history of nephrolithiasis and recurrent urinary tract infection (UTI) who presented to the emergency department with back pain. CT revealed a malrotated right kidney with a large renal stone and possible fistulous connection between the second portion of the duodenum and the right renal collecting system. Technetium-99m scintigraphy confirmed presence of the fistula. The patient declined intervention and was discharged from the hospital with oral antibiotic suppressive therapy...

Infections caused by extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) have become increasingly prevalent, posing a serious public threat worldwide. It is commonly believed that untreated urinary tract infections (UTI) and asymptomatic bacteriuria (ABU) during pregnancy are associated with poor obstetric outcomes. Currently, there is a paucity of data regarding the outcomes or risk factors of such ESBL-E infections in pregnant women. We conducted a retrospective 1:2 matched case-control study of hospitalised pregnant women with ESBL-E- vs...

Uropathogenic Escherichia coli (UPEC) strains cause most uncomplicated urinary tract infections (UTIs). These strains are a subgroup of extraintestinal pathogenic E. coli (ExPEC) strains that infect extraintestinal sites, including urinary tract, meninges, bloodstream, lungs, and surgical sites. Here, we hypothesize that UPEC isolates adapt to and grow more rapidly within the urinary tract than other E. coli isolates and survive in that niche. To date, there has not been a reliable method available to measure their growth rate in vivo Here we used two methods: segregation of nonreplicating plasmid pGTR902, and peak-to-trough ratio (PTR), a sequencing-based method that enumerates bacterial chromosomal replication forks present during cell division...

CASE DESCRIPTION 4 cats were examined because of ureteral obstruction. CLINICAL FINDINGS Clinical and clinicopathologic abnormalities were nonspecific and included anorexia, lethargy, weight loss, anemia, leukocytosis, neutrophilia, lymphopenia, and azotemia. A diagnosis of pyonephrosis was made in all cats. The presence of bacteriuria was confirmed by means of urinalysis in 2 cats, bacterial culture of a urine sample obtained by means of preoperative cystocentesis in 2 cats, and bacterial culture of samples obtained from the renal pelvis intraoperatively in 3 cats...

OBJECTIVE: To evaluate GBS colony numbers in the urine at 35-37 weeks' gestation to predict the load of GBS-colonization of the vagina at birth. STUDY DESIGN: In this prospective observational study, we included 902 unselected pregnant women. Exposure was GBS colony forming units (CFU) per mL urine at 35-37 weeks' gestation. Outcome was vaginal GBS colonization at birth as assessed by a semi-quantitative culture of a vaginal swab sample (negative, +1, +2, +3). RESULTS: Bacteriuria with GBS at 35-37 weeks' gestation performed with a sensitivity of 30% concerning any degree of vaginal GBS colonization at birth (31 of 104 cases); 19% for light (+1), 17% for medium (+2), and 52% for high load (+3) vaginal GBS colonization...

Asymptomatic bacterial colonization of the urinary bladder (asymptomatic bacteriuria, ABU) can prevent bladder colonization by uropathogens and thus symptomatic urinary tract infection (UTI). Deliberate bladder colonization with Escherichia coli ABU isolate 83972 has been shown to outcompete uropathogens and prevent symptomatic UTI by bacterial interference. Many ABU isolates evolved from uropathogenic ancestors and, although attenuated, may still be able to express virulence-associated factors. Our aim was to screen for efficient and safe candidate strains that could be used as alternatives to E...

BACKGROUND: Staphylococcus aureus bacteriuria (SABU) concomitant to S. aureus bacteremia (SAB) has been associated with deep-seated infections and worse prognosis. However, the relevant studies were small and inconsistent. Here, we aim to provide a review of the relevant literature, and a meta-analysis of these studies. METHODS: We searched PubMed and Scopus for studies comparing patients with SAB and concomitant SABU to patients with SAB without SABU. RESULTS: Nine relevant studies were identified, involving 1429 patients with SAB, of whom 18...

Early-onset neonatal bacterial sepsis (EOS) is sepsis occurring within the first 7 days of life. This statement provides updated recommendations for the care of term (≥37 weeks' gestational age) newborns at risk of EOS, during the first 24 hours of life. Maternal Group B streptococcus (GBS) colonization in the current pregnancy, GBS bacteriuria, a previous infant with invasive GBS disease, prolonged rupture of membranes (≥18 hours) and maternal fever (temperature ≥38°C) are the factors most commonly associated with EOS...
