ABSTRACT

Platelet counts in reactive thrombocytosis rarely exceed 1000 × 109/L. We present the case of a male patient, aged 80 years, with quiescent rheumatoid arthritis who was found to have a platelet count of 1011 × 109/L on routine laboratory testing. The patient was initially asymptomatic but developed leukocytosis to 23.1 × 109/L on hospital day 2. Diagnostic work-up revealed obstructive nephrolithiasis and pyelonephritis, and the thrombocytosis and leukocytosis gradually resolved with empiric antibiotic treatment and ureteral stent placement. Tests for myeloproliferative disorders, including JAK-2V617F mutation, BCR-ABL for chronic myeloid leukemia and acute lymphocytic leukemia, and myeloproliferative neoplasms (MPL/CALR), were negative. Physicians should be aware that in rare cases reactive thrombocytosis can exceed 1000 × 109/L, and that markedly elevated platelet counts in the setting of urinary tract infections may be an early sign of obstructive uropathy.

ABSTRACT

To identify the best combination of potential predictors of septic shock in patients with obstructive acute pyelonephritis associated with ureteral stones (OAPN-US) according to Sepsis-3 criteria. Patients who underwent percutaneous nephrostomy (PCN) with OAPN-US were retrospectively evaluated. Recursive feature elimination (RFE) was applied to patients with and without septic shock to identify factors associated with the prediction of progression to septic shock. We compared combinations of the selected features based on area under the receiver operating curve (AUROC) to determine which combination was most effective. This study included 81 patients who were treated with PCN due to OAPN-US. A comparison was made between 37 patients with septic shock (SS) and 44 patients without septic shock (NSS). SS group had a higher age, poorer Eastern Cooperative Oncology Group status, and significantly higher levels of positivity in urine cultures and blood cultures. There were also differences in laboratory tests between the 2 groups. Procalcitonin (PCT), international normalized ratio (INR), and absolute lymphocyte count (ALC) were selected based on RFE. We compared the predictive power for SS when each marker was used alone, when 2 markers were combined, and when all 3 markers were combined. Among these combinations, using all 3 variables together yielded the highest AUROC of 0.942. Of the 3 variables, PCT had the highest Gini importance score, indicating that it was the most influential factor. Clinical characteristics were different between the SS and the NSS groups. In patients with OAPN-US, the combination of PCT, ALC, and INR was an excellent predictor of septic shock.

ABSTRACT

Urinary tract infections (UTIs), including cystitis and pyelonephritis, are common. Each year, they account for more than 10 million outpatient visits and more than 3 million emergency department visits. Recurrent UTIs (defined as three in 1 year or two in 6 months) also are common, occurring in 20% to 30% of women. The annual incidence of UTIs is 12.1% among women and 3% among men. Cystitis symptoms include lower abdominal pain, dysuria, and urinary urgency or frequency. Escherichia coli is the most common pathogen. Cystitis often is diagnosed inappropriately when patients have asymptomatic bacteriuria (ie, positive urine culture result without symptoms). This can result in unnecessary antibiotic therapy. For uncomplicated acute cystitis in women, guidelines recommend nitrofurantoin for 5 days, trimethoprim-sulfamethoxazole for 3 days (if local drug-resistance rates are less than 20%), fosfomycin in a single dose, or pivmecillinam for 5 days. Effective prophylactic options for UTI include antibiotics and vaginal estrogen for postmenopausal women. Antibiotics are most effective but are associated with a risk of increased drug resistance. Patients with pyelonephritis present with costovertebral tenderness, fever, and urinary symptoms. Third-generation cephalosporins are preferred for management. Significant complications of pyelonephritis include sepsis or septic shock, obstructive pyelonephritis, emphysematous pyelonephritis, perinephric abscess, and kidney transplant rejection. For pregnant patients with pyelonephritis, hospitalization and intravenous antibiotics are indicated.

ABSTRACT

Acute pyelonephritis (AP) is a severe urinary tract infection (UTI) syndrome with a large population of patients worldwide. Current approaches to confirming AP are limited to urinalysis, radiological imaging methods and histological assessment. Fourier transform infrared (FTIR) microspectroscopy is a promising label-free modality that can offer information about both morphological and molecular pathologic alterations from biological tissues. Here, FTIR microspectroscopy serves to investigate renal biological histology of a rat model with AP and classify normal cortex, normal medulla and infected acute pyelonephritis tissues. The spectra were experimentally collected by FTIR with an infrared Globar source through raster scanning procedure. Unsupervised analysis methods, including integrating, clustering and principal component analysis (PCA) were performed on such spectra data to form infrared histological maps of entire kidney section. In comparison to Hematoxylin & Eosin-stained results of the adjacent tissue sections, these infrared maps were proved to enable the differentiation of the renal tissue types. The results of both integration and clustering indicated that the concentration of amide II decreases in the infected acute pyelonephritis tissues, with an increased presence of nucleic acids and lipids. By means of PCA, the infected tissue was linearly separated from normal ones by plotting confident ellipses with the score values of the first and second principal components. Moreover, supervised analysis was performed based on the supported vector machines (SVM). Normal cortex, normal medulla and infected acute pyelonephritis tissues were classified by SVM models with the best accuracy of 96.11% in testing dataset. In addition, these analytical methods were further employed on synchrotron-based FTIR spectra data and successfully form high-resolution infrared histological maps of glomerulus and necrotic cell mass. This work demonstrates that FTIR microspectroscopy will be a powerful manner to investigate AP tissue and differentiate infected tissue from normal tissue in a renal infected model system.

ABSTRACT

Here, we describe an interesting case of a patient with the duplication of inferior vena cava, high-positioned bifurcation of the abdominal aorta with transposition of iliac arteries, and right renal aplasia associated with end-stage renal disease who underwent kidney transplant. In this case, the patient with anorectal malformations with a vaginal fistula was prepared and underwent a kidney transplant. During the surgery, we discovered duplicated inferior vena cava and transposed iliac arteries. After the surgery, computed tomography angiography revealed the inferior vena cava duplication with the 2 connections between the right and left inferior vena cava with the formation of an anomalous circle, high-positioned bifurcation of the abdominal aorta at the level of the L2 vertebral body, and transposition of right and left iliac arteries. Also, we observed the right kidney aplasia and absence of blood circulation in the left native kidney. In our case, a delayed diagnosis of pyelonephritis resulted in the progression to end-stage renal disease that necessitated a kidney transplant, during which we found these anomalies. We confirmed the asymptomatic course of these anomalies, diagnosed only during radiological imaging or surgical intervention. Patients with congenital anomalies of the kidney and urinary tract should undergo complete investigations before surgical decisions. Diagnosis of this pathology in the preoperative period, especially in transplant patients, will alert the surgery team in advance of the operation and allow preparation for the intraoperative difficulties that are typically associated with anomalies such as inferior vena cava transposition or aplasia.

ABSTRACT

Urinary tract infections caused by Aerococcus urinae have rarely been reported in children, and the clinical characteristics remain unclear. We reviewed medical records of children whose urine cultures grew A. urinae (≥104 CFU/mL) at a tertiary children's hospital in Tokyo, Japan. We found 17 pediatric patients in a review of 22,769 urine cultures between June 2006 and May 2022. The median age of 17 patients was 10.7 years (IQR 8-13 years), and males represented 76.5 % of the patients. Sixteen patients (94.1 %) had underlying urological conditions (neurogenic bladder, vesicoureteral reflux, urethral stenosis, bladder exstrophy, or urinary catheterization). The chief symptoms were fever (35.3 %), malodorous urine (23.5 %), nausea (11.8 %), and back pain (5.9 %). Ten patients were asymptomatic. Pyelonephritis was diagnosed in five male patients. All of them had underlying abnormal conditions of the bladder, and two had malodorous urine. All patients had favorable outcomes after 10-14 days of ampicillin/amoxicillin-based antimicrobial therapy.

ABSTRACT

Urinary tract infections (UTIs) are serious bacterial infections affecting children of all ages. An understanding of the methods of urine collection is important to prevent the contamination of urine specimens and to interpret results. The diagnosis of a UTI requires appropriate interpretation of both urinalysis and urine culture results because testing must indicate evidence of inflammation and the presence of bacteria. Rapid treatment of UTIs is imperative to prevent acute decompensation and systemic illness. Empiric antibiotics should be narrowed as soon as possible to tailor antibiotic treatment and limit antibiotic overuse. Imaging with a renal ultrasound scan is recommended for all infants with first febrile UTIs rather than a voiding cystourethrogram. An additional goal of UTI treatment is to prevent renal scarring, which can lead to lifelong health consequences. Children with anatomic abnormalities of the urinary tract and those who have recurrent UTIs are at increased risk of renal scarring. [Pediatr Ann. 2024;53(6):e217-e222.].

ABSTRACT

The aim of the study was to investigate the peculiarities of morphometric parameters of peripheral blood lymphocytes in chronic pyelonephritis in elderly patients in comparison with young and middle-aged patients. A total of 81 patients with chronic pyelonephritis in the exacerbation phase were examined. All patients were divided into three age groups according to WHO recommendations: the 1st - 42patients of young age (18-44 years); the 2nd - 17 patients of middle age (45-59 years); the 3rd - 22 elderly patients (60-74 years). Computer morphometry of lymphocytes was performed in all examined patients. In elderly patients with chronic pyelonephritis the size and сytoplasmic-nuclear ratio of lymphocytes increase. This indicates the preservation of lymphocyte defense responses at this age. In male patients with chronic pyelonephritis in the 1st and 2nd age groups the size of lymphocytes increases, and in female patients - decreases. The сytoplasmic-nuclear ratio increases in males of these age groups, while it remains unchanged or decreases in females. Indirect indications of reduced immunity in young and middle-aged women with chronic inflammation in the kidneys have been obtained.

ABSTRACT

OBJECTIVES: Modern immunosuppressive regimens have reduced rejection episodes in renal allograft recipients but have increased the risk of opportunistic infections. Infections are considered to be the second leading cause of death after cardiovascular complications in renal allograft recipients. Data on opportunistic infections affecting the allograft itself are scarce. The present study describes the spectrum of renal opportunistic infections and their outcomes diagnosed on renal allograft biopsies and nephrectomy specimens. MATERIALS AND METHODS: Our retrospective observational study was conducted from December 2011 to December 2021. We analyzed infectious episodes diagnosed on renal allograft biopsies or graft nephrectomy specimens. We obtained clinical, epidemiological, and laboratory details for analyses from hospital records. RESULTS: BK virus nephropathy was the most common opportunistic infection affecting the allograft, accounting for 47% of cases, followed by bacterial graft pyelonephritis (25%). Mucormycosis was the most common fungal infection. The diagnosis of infection from day of transplant ranged from 14 days to 39 months. Follow-up periods ranged from 1 to 10 years. Mortality was highest among patients with opportunistic fungal infection (62%), followed by viral infections, and graft failure rate was highest in patients with graft pyelonephritis (50%). Among patients with BK polyomavirus nephropathy, 45% had stable graft function compared with just 33% of patients with bacterial graft pyelonephritis. CONCLUSIONS: BK polyoma virus infection was the most common infection affecting the renal allograft in our study. Although fungal infections caused the highest mortality among our patients, bacterial graft pyelonephritis was responsible for maximum graft failure. Correctly identifying infections on histology is important so that graft and patient life can be prolonged.

ABSTRACT

BACKGROUND: The diagnosis of pyelonephritis in cats is challenging and development of a noninvasive and accurate biomarker is needed. HYPOTHESES: Serum amyloid A (SAA) is increased in cats with pyelonephritis, but not in cats with other urinary tract diseases. ANIMALS: A cohort of 125 cats (149 observations). METHODS: This was a prospective study. Group 1 included cats with a diagnosis of pyelonephritis either confirmed by bacterial culture of pelvic urine (Group 1a) or presumed (1b). Group 2 included cats for which pyelonephritis was ruled out (with certainty: Group 2a or judged unlikely: Group 2b). SAA concentration was compared between groups, and accuracy of SAA for the diagnosis of pyelonephritis was calculated using a Receiver Operating Characteristic (ROC) curve analysis. RESULTS: Median SAA concentration was significantly higher in Group 1a (86.8 mg/L [73.3; 161.5]; n = 8) than in Group 2a (4 mg/L [1.8; 5.6], n = 19; P < .001) and in Group 2b (5.4 mg/L [3.1; 9.7], n = 113; P < .001). It was also significantly higher in Group 1b (98.8 mg/L [83.1; 147.3]; n = 9) than in Group 2b (P < .001) and Group 2a (P < .001). Optimal diagnostic cut-off for SAA concentration was 51.3 mg/L. yielding a sensitivity of 88% (95% confidence interval: [64%; 99%]) and a specificity of 94% (95% confidence interval: [88%; 97%]). CONCLUSIONS AND CLINICAL IMPORTANCE: Measurement of SAA could be used to rule out pyelonephritis in the case of low suspicion of the disease. Increased SAA concentration is suggestive of pyelonephritis despite a lack of specificity.

ABSTRACT

Salmonella enterica subspecies enterica serovar Choleraesuis (S. Choleraesuis) is a nontyphoidal Salmonella pathogen that causes swine paratyphoids. S. Choleraesuis is a zoonotic pathogen transmitted to humans via contaminated food and causes sepsis. Here, we report a rare case of pyelonephritis caused by S. Choleraesuis in a Japanese patient with a carcinoma of unknown primary origin. On the day of admission, the patient was diagnosed with pyelonephritis associated with ureteral stent obstruction. He had no history of raw pork consumption or gastrointestinal symptoms. Gram-negative rods were isolated from urine and blood cultures, identified as Salmonella enterica subsp. enterica using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The serological typing results were O7: -: 1 and 5; however, the serotypes could not be determined. The isolate was identified as S. Choleraesuis using multilocus sequence typing, nucleotide sequence analysis of the fliC gene, and biochemical examination. Four days after a 14-day course of intravenous piperacillin-tazobactam (9 g/day), the patient showed relapse of the condition. Subsequently, the patient was treated with intravenous ceftriaxone (2 g/day) and oral amoxicillin (1000 mg/day) for 14 days each; recurrence was not observed. This novel case of pyelonephritis with bacteremia was caused by S. Choleraesuis in Japan. Conventional testing methods could not identify the serotypes; however, the case highlights the importance of adopting advanced diagnostic techniques based on molecular biology to ensure accurate pathogen identification.

ABSTRACT

BACKGROUND: In the emergency department (ED), pyelonephritis is a fairly common diagnosis, especially in patients with unilateral flank pain. Xanthogranulomatous pyelonephritis (XGP) is a rare type of pyelonephritis that is associated with unique features, which may lead to its diagnosis. CASE REPORT: A 30-year-old male patient presented to the ED for evaluation of right-sided abdominal pain that has been ongoing for the past 24 hours. He noted the pain was located predominantly in the right flank and described it as sharp in nature. The pain was nonradiating and was associated with scant hematuria. He stated that he had similar pains approximately 1 month earlier that resolved after a few days. The patient underwent a bedside ultrasound and a subsequent computed tomography (CT) scan of the abdomen and pelvis, which showed an enlarged, multiloculated right kidney with dilated calyces and a large staghorn calculus, findings that represent XGP. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report highlights an unusual variant of pyelonephritis, a relatively common ED diagnosis. XGP should be considered in patients with recurrent pyelonephritis, as treatment for XGP may require surgical intervention in addition to traditional antibiotic management.

ABSTRACT

INTRODUCTION: Antibiotic resistance is a worldwide concern. No study has ever examined the correlation between ethnicity and antibiotic resistance. We examined those parameters among hospitalized pregnant patients diagnosed with pyelonephritis. AIMS: Should ethnic origin play a role in optimizing antibiotic therapy? To better comprehend, we have chosen a cohort of hospitalized pregnant patients with a pyelonephritis diagnosis. METHODS: A total of 105 cases of patients hospitalized in the Shamir Medical Center between the years 2017-2020 were analysed. Feto-maternal outcomes and antibiotic resistance in relation to ethnicity were plotted statistically using chi-square tests (Arab, 40%; North Africa, 13%; Europe-Ashkenaz,10%; Ethiopia/Iran/Kavkaz/Iraq/other, 3%; Turkey/Uzbekistan/Yemen 2%). RESULTS: Ethnic groups included Arab (40%), others referred as "None-Arab". The antibiotic resistance panel revealed differences comparing the two largest groups (Arab% VS non-Arab%), whereas there was no correlation between any ethnic group and obstetrics parameter. Arab women were more resistant to ciprofloxacin (33% vs 7%, P= 0.026) and less sensitive to imipenem (60% vs 90.9%, P= 0.03); less sensitive to ceftriaxone and cefuroxime. CONCLUSIONS: There was a correlation between ethnic origin of pregnant patients diagnosed with pyelonephritis and antibiotic resistance. We hope ethnicity, might, in some cases, assist physicians choosing the optimal therapy.

ABSTRACT

BACKGROUND: One of the most common bacterial infections in childhood is urinary tract infection (UTI). Toll-like receptors (TLRs) contribute to immune response against UTI recognizing specific pathogenic agents. Our aim was to determine whether soluble TLR4 (sTLR4), soluble TLR5 (sTLR5) and interleukin 8 (IL-8) can be used as biomarkers to diagnose UTI. We also aimed to reveal the relationship between urine Heat Shock Protein 70 (uHSP70) and those biomarkers investigated in this study. METHODS: A total of 802 children from 37 centers participated in the study. The participants (n = 282) who did not meet the inclusion criteria were excluded from the study. The remaining 520 children, including 191 patients with UTI, 178 patients with non-UTI infections, 50 children with contaminated urine samples, 26 participants with asymptomatic bacteriuria and 75 healthy controls were included in the study. Urine and serum levels of sTLR4, sTLR5 and IL-8 were measured at presentation in all patients and after antibiotic treatment in patients with UTI. RESULTS: Urine sTLR4 was higher in the UTI group than in the other groups. UTI may be predicted using 1.28 ng/mL as cut-off for urine sTLR4 with 68% sensitivity and 65% specificity (AUC = 0.682). In the UTI group, urine sTLR4 levels were significantly higher in pyelonephritis than in cystitis (p < 0.0001). Post-treatment urine sTLR4 levels in the UTI group were significantly lower than pre-treatment values (p < 0.0001). CONCLUSIONS: Urine sTLR4 may be used as a useful biomarker in predicting UTI and subsequent pyelonephritis in children with UTI. A higher resolution version of the Graphical abstract is available as Supplementary information.

ABSTRACT

Pyelonephritis is a prevalent diagnosis of emergency department visits. It commonly presents as flank pain and costovertebral tenderness with urinary symptoms. However, some cases occur without typical symptoms. Our study highlights the dubious presentation of pyelonephritis with lower urinary tract symptoms (LUTS) only. This study was conducted at a tertiary care hospital, where charts and files were reviewed from January 11, 2018 to February 28, 2019 for all the patients with a diagnosis of acute pyelonephritis from medical records. In our study, 521 patients were included and 492 (94%) of the participants were suffering from pyelonephritis. Approximately 22.8% of the patients showed the absence of both flank pain and costovertebral tenderness but were diagnosed with pyelonephritis based on computed tomography (CT) and magnetic resonance imaging (MRI). Moreover, 27% of the patients reported upper urinary tract symptoms only and were diagnosed by CT or MRI findings. Out of that only 24% and 16% of the patients reported flank pain and costovertebral tenderness, respectively. Insignificant associations with pyelonephritis were found for age, gender and other comorbidities. Our study showed a significant number of patients with pyelonephritis without any upper urinary tract symptoms. Patients with LUTS should be evaluated further by imaging if they belong to the high-risk population.

ABSTRACT

RATIONALE: To describe the diagnostic and treatment approaches of renal abscesses complicated with acute pyelonephritis in children. PATIENT CONCERNS: Two children presented with fever, vomiting, and abdominal pain with no typical manifestations, like frequent urination, urgency, dysuria, hematuria, foam urine, and lumbago. Renal abscess complicating acute pyelonephritis was diagnosed by B-ultrasound and computed tomography enhancement. Moreover, inflammatory markers were elevated significantly, but routine blood and urine cultures were repeatedly negative. The empirical anti-infection therapy had no obvious effect. A pathogenic diagnosis was confirmed in case two, and macro gene detection in blood and urine guided the follow-up treatment. DIAGNOSES: Both children were diagnosed with acute gastroenteritis on admission, but renal abscess complicating acute pyelonephritis were diagnosed by imaging examination. INTERVENTIONS: Both children were given anti-infection therapy of third-generation cephalosporin, which had no obvious effect. Routine blood and urine cultures were repeatedly negative. Case one was changed to piperacillin sodium tazobactam. We further carried out blood and urinary metagenomic next-generation sequencing detection for case two. Meanwhile, meropenem and linezolid anti-infection treatment was given. The results showed overlapping infection with Escherichia coli and Enterococcus faecalis. According to the genetic test results, amoxicillin clavulanate potassium combined with nitrofurantoin were prescribed after discharge. OUTCOMES: Clinical symptoms of the 2 children disappeared, the infection was controlled, and imaging showed that renal abscess complicated with acute pyelonephritis disappeared. LESSONS: The clinical spectrum of renal abscess complicating acute pyelonephritis is vague, with no specific manifestations, and can be easily misdiagnosed. B-ultrasound and computed tomography enhancement are helpful in making a definite diagnosis. Moreover, the sensitivity of routine culture is low, and metagenomic next-generation sequencing might be helpful to detect pathogenic microorganisms and guided treatment. Early treatment with broad-spectrum antibiotics might have favorable outcomes.

ABSTRACT

INTRODUCTION: Our study aimed to evaluate the performance of Quick Sepsis-related Organ Failure Assessment (qSOFA), Modified Early Warning Score (MEWS), National Early Warning Score (NEWS), Systemic Inflammatory Response Syndrome (SIRS), and Global Research in the Emphysematous Pyelonephritis group (GREMP) in predicting the need of admission in intensive care units (ICU) for emphysematous pyelonephritis (EPN) patient. PATIENTS AND METHODS: In this retrospective study, we reviewed 70 patients admitted to our department from January 2008 to October 2022. Data on clinical presentation and EPN management were noted. The five scoring systems were calculated by one investigator. Univariate and multivariate analyses were used to assess predictive factors of severe sepsis and mortality. Statistical analysis was made using SPSS version 22. RESULTS: Mean age was 61.83 years with 65.7% diabetes. As per Huang and Tseng classification, 41 patients had class I EPN, 7 had class II EPN, 8 had class IIIa, 6 class IIIB EPN, and 8 had class IV EPN. Seventeen patients (24.28%) were admitted to ICU with an 18.57 mortality rate. Univariate analysis showed that ICU admission was significantly associated with higher respiration rate and heart rate, lower systolic blood pressure, confusion, CRP, lactate and creatinine serum (p = 0.0001, p = 0.0001, p = 0.001, p = 0.007, p = 0.004, p = 0.001, p = 0.001, respectively). All five scores and Huang and Tseng classification were significantly predictive of admission to ICU. All five scores showed good results under the area curves to predict ICU entry with 0.915, 0.895, 0.968, 0.887, and 0.846 for qSOFA, MEWS score, NEWS score, SIRS, and GREMP score, respectively. CONCLUSION: NEWS score seemed to be the best performing physiologic score among the five scoring systems studied and may help with biological and radiological findings to quickly identify EPN patients that need intensive care unit.

ABSTRACT

SUMMARY: Urinary tract infection (UTI) is one of the more common perinatal complications, affecting approximately 8% of pregnancies (1, 2). These infections represent a spectrum, from asymptomatic bacteriuria, to symptomatic acute cystitis, to the most serious, pyelonephritis. The presence of UTIs has been associated with adverse pregnancy outcomes, including increased rates of preterm delivery and low birth weight. Screening for and treating asymptomatic bacteriuria have been shown in multiple studies to reduce the incidence of pyelonephritis in pregnancy (3-5). Given the frequency at which UTIs are encountered in pregnancy, the ability to recognize, diagnose, and treat them is essential for those providing care to pregnant individuals. This Clinical Consensus document was developed using an established protocol in conjunction with the authors listed.
