SETTING: There are concerns about the occurrence of multidrug resistance (MDR) in patients with urine tract infections (UTI) in Nepal.OBJECTIVE: To determine culture positivity, trends in MDR among Escherichia coli and Klebsiella pneumoniae infections and seasonal changes in culture-positive UTI specimens isolated from 2014 to 2018 at the B P Koirala Institute of Health Sciences, Dharan, Eastern Nepal.DESIGN: This was a cross-sectional study using secondary laboratory data.RESULTS: Among 116,417 urine samples tested, 19,671 (16.9%) were culture-positive, with an increasing trend in the number of samples tested and culture positivity. E. coli was the most common bacteria (54.3%), followed by K. pneumoniae (8.8%). Among E. coli and K. pneumoniae isolates, MDR was found in respectively 42.5% and 36.0%. MDR was higher in males and people aged >55 years, but showed a decreasing trend over the years. The numbers of isolates increased over the years, with a peak always observed from July to August.CONCLUSION: Low culture positivity is worrying and requires further work into improving diagnostic protocols. Decreasing trends in MDR are a welcome sign. Information on seasonal changes that peak in July–August can help laboratories better prepare for this time with adequate buffer stocks to ensure culture and antibiotic susceptibility testing.

Background: Urinary tract infections are a common occurrence in pregnancy. The physiological and anatomical changes associated with pregnancy predispose to UTIs. Main aim of the study is to determine the prevalence of asymptomatic bacteriuria in pregnant women, to identify the commonest microorganisms and antibacterial susceptibility of the isolated organism and to study the adverse maternal and fetal outcome.Methods: Prospective cross sectional study, conducted between July 2016 to July 2017 in a tertiary hospital. All pregnant women without the symptoms of UTI attending prenatal checkups were included, they were evaluated with urine microscopy and culture sensitivity.Results: Out of 250 pregnant women, 24 urine samples were contaminated and were excluded from the study.165 pregnant women had sterile culture. 10 women had insignificant bacteruria. 30 women had significant growth on culture. 2 of the culture positive women and 21 culture negative women lost for follows. So total number of culture positive women were 28 so incidence of asymptomatic bacteruria is 13.7%.Conclusions: Routine urine culture sensitivity even in asymptomatic women should be offered during antenatal visits so that adverse maternal and fetal outcomes can be prevented.

Abstract Purpose: PIDs associates with autoimmune diseases include autoimmune liver diseases (AILD); however, the frequency of PIDs among patients with AILD is unknown. This study aimed to evaluate the strength of the association between AILD and PIDs. Methods: We conducted this single-center, cross-sectional, and descriptive study in a tertiary hospital. We evaluated eighty-two patients with AILD (39 autoimmune hepatitis (AIH), 32 with primary biliary cholangitis (PBC), seven with variant syndromes (VS), and four with primary sclerosing cholangitis (PSC) for the presence of PIDs. We obtained a detailed history of infections, comorbidities, family history, and laboratory data from the files. All patients were evaluated in the immunology department for further examination, and PID diagnoses were made according to ESID (The European Society for Immunodeficiencies) criteria. Results: Out of 82 patients with AILD, PIDs were diagnosed in 18% (15 patients); there were four patients with common variable immunodeficiency (CVID), four with partial IgA deficiency (PIgAD), four with selective IgM deficiency (SIgMD), and three with combined immunodeficiency (CID). PIDs were present in 29% of patients with VS, 25 % of patients with PSC, 23% of patients with AIH, and 9% of patients with PBC. Conclusion: Although PIDs are rare diseases in the general population, they have a strong association with AILD and were detected in one-fifth of the patients. Further research with larger patient groups is needed to evaluate the diagnostic and prognostic impacts of PIDs on AILD.

Globally, urinary tract infections are one of the most common infections in need of urgent clinical attention. The prevalence of extended spectrum beta-lactamases (ESBL)- producing Escherichia coli isolated from urine samples of some UTI patients and s of apparently healthy individuals in Minna, Nigeria, is investigated. Standard microbiological techniques were used to conduct this study. A total of 170 catch midstream urine samples submitted to the Medical Microbiology Laboratories of 4 different hospitals (and samples from healthy individuals) were randomly collected for 5 months and examined for microbial growths. Female patients (65.9%) submitted more urine samples for UTI test than their male counterpart (34.1%). The age ranges of 21 -30 (26.5%) and 31 - 40 (25.3%) had the highest percentages of infection rate while those within the ages 1- 10 (3.5%) and ≥ 71 (2.3%) were the least infected. This study observed a prevalence of 23.5% of E. coli in Minna metropolis and a significant number (30%) of healthy individuals (HI) was observed to harbor the E. coli in their urine. The isolates were highly susceptible to Gentamicin (65%), Ofloxacin (65%), Tetracycline (62.5%), Cotrimoxazole (62.5%), and Streptomycin (57.5%). Mildly susceptible to Pefloxacin (37.5%), Chloramphenicol (37.5%), and Ciprofloxacin (35%). There were significant resistance to most of the beta-lactames tested [Cefuroxime (80%), Amoxicillin (42.5%), Augmentin (40), Cefotaxime (20%) and Ceftaxidime (7.5%)]. Two of the isolates were resistant to all the 13 antibiotics tested; 70% (28) of the isolates had multiple antibiotics resistance index (MARI) ≥0.3. Multidrug resistance was expressed in 37.5% of the isolates tested. The study showed a vast resistant pool in the environment. Only 25% of the E. coli isolated from the urine samples produced beta-lactamases phenotypically, most of which expressed resistance to more than 5 of the antibiotics tested and had MARI of ≥ 0.5. Further evaluation showed that 25% (10/40) of the E. coli isolated from the UTI patients in Minna, Nigeria, were ESBL- producers and could harbor one or two of the genes. TEM gene was expressed in 70% (7) of the isolates that produced ESBL phenotypically, 60% 6) harbored CTXM gene, 20% (2) had the OXA gene while none of the bacteria harbored the SHV gene. The study established a 5.9% ESBL prevalence among the E. coli isolated from UTI in the environment studied. This study established that E. coli is one of the prevalent bacteri urea majorly isolated from UTI patients in Minna. The prevalent E. coli are multidrug resistant and could harbor more than one ESBL gene . keywords: Escherichia coli, Minna, UTI, ESBL, Multidrug resistance

BACKGROUND Urinary tract infections (UTI) constitute a common cause of morbidity in infants and children. When associated with abnormalities of urinary tract, they may lead to long-term complications including renal scarring, loss of function and hypertension. Most urinary tract infections remain undiagnosed if investigations are not routinely performed to detect them. Prompt detection and treatment of urinary tract infections and any complicating factors are important. The objective of the study is to know the clinical, epidemiological and bacteriological profile (i.e. clinical signs and symptoms, age, sex, family history, associated urinary tract abnormalities, & causative organisms) of urinary tract infections in febrile children with culture positive urinary tract infection. METHODS This descriptive, cross sectional observational study was conducted at outpatient clinics of our “child health clinics” between May 2016 and April 2017 (one year). All children aged 0 to 12 years with culture positive urinary tract infections were included in this study to evaluate the clinical, epidemiological and bacteriological profile. RESULTS A total of 69 children with culture positive urinary tract infections were included in this study. Out of 69 children included in this study, 36 (52.2 %) were females and 33 (47.8 %) were males. Overall female preponderance was seen and the M: F ratio was 0.9:1. But during first year of life in our study group we had more boys (10, 14.49 %) affected with urinary tract infection than girls. 49.3 % of urinary tract infections in the present study belonged to lower socio-economic status. Most common organism causing urinary tract infection in our group was E. coli (56.5 %). Fever (100 %), anorexia or refusal of feeds (52.2 %), dysuria (46.4 %), vomiting (46.4 %) and abdominal pain (39.1 %) were the predominant clinical manifestations observed in our study. CONCLUSIONS Urinary tract infection is a common medical problem in children and it should be considered as a potential cause of fever in children. As febrile children with urinary tract infection usually present with non-specific signs and symptoms, urine culture should be considered as a part of diagnostic evaluation.

Abstract Background Procalcitonin (PCT) and c-reactive protein (CRP) have been utilized in children to assess risk for serious bacterial infections. However, there have been different cut-offs reported for PCT and CRP, which yield different sensitivity and specificity. This study aims to compare the sensitivity and specificity of PCT and CRP in detecting serious bacterial infections (SBIs), specifically urinary tract infections, bacteremia and meningitis. Methods In this retrospective, single center cohort study from January 2018 to June 2019, we analyzed children with a fever greater than 38C with both PCT and CRP value within 24 hours of admission. Each patient had a blood, urine and/or cerebrospinal fluid culture collected within 48 hours of admission. No antibiotics were administered from the admitting hospital prior to collection of the PCT or CRP. Our gold standard was a positive culture obtained from blood, cerebrospinal fluid, or urine. The statistical analysis included categorical variables as percentages and compared them using the Fisher exact test. The optimal cutoff values for PCT or CRP were based on ROC curve analysis and Youden Index. Sensitivity and specificity analysis were based on literature review cut offs and ROC curves cut offs. Results Among 202 children, we had 45 culture positive patients (11 urinary tract infections, 4 meningitis, and 32 bacteremia). The patients with culture positivity had higher PCT levels (7.9 ng/mL vs 2.5 ng/mL, P=0.0111), CRP levels (110.9 mg/L vs 49.6 mg/L, P<0.0001) and temperature (39.2C vs 39C, P<0.0052). The area under the curve (AUC) comparing culture positivity vs negativity for all culture types was 0.72 (p<0.0001) for PCT and 0.66 (p=0.001) for CRP. In Figure 1, the AUC for culture positive bacteremia was 0.68 (p=0.0011) for PCT and 0.70 (p=0.0003). The AUC for culture positive urinary tract infections (UTI) only was 0.86 (p=0.0001) for PCT and 0.70 (p=0.3607). For the cut-off value for PCT at 0.5 ng/mL, the sensitivity and specificity was 64% (95% confidence interval [CI] 0.5–0.77) and 70% (95% CI 0.62–0.77) respectively in identifying children with bacterial infection. For the cut-off value for CRP at 20 mg/L, the sensitivity and specificity was 67% (95% CI 0.52–0.79) and 52% (95% CI 0.44–0.59) respectively in identifying children with bacterial infection. Conclusion In this study, PCT and CRP are nearly equivalent classifiers for detecting SBIs as a group and bacteremia, but PCT is statistically better for urinary tract infections; however, the clinical utility is unknown.

Oversight of information on biochemistry requisition forms may lead to laboratory errors. The aim of this study was to evaluate the level of completion of these forms. The observational cross-sectional study was conducted between December 2014 and March 2015 in the biochemistry department of a tertiary hospital in Kathmandu after approval by the Institutional Ethical Review Committee. Two thousand and thirty nine request forms were randomly assessed for the completeness of information provided by the requesting physician. Microsoft excels software and SPSS-17 was used for analysis. Patient confidentiality was maintained. Out of 2039 request forms examined, the only 100% documented parameter was the pa­tient’s name. Date of specimen collection was recorded in 79.74% of forms and age in 98.53%. The working diagnosis was recorded in 28.44% but no information regarding patient preparation. While the consultants name were stated in 13.29% of cases, drug history in 0.24%. Parameters like gender were recorded in 98.82%, sample type in 0.29%. Whether the patient was present in the ward or in the outpatient department was documented in 15.11% whereas patient number in 38.35%. Doctors were more likely to sign the forms rather than providing their name/designation. This study demonstrates that the custom of completion of request forms was poor. As laboratory data plays a significant role in medical diagnosis and re­search, incomplete data provided to the laboratory could significantly impact on the comments and successful outcome of treatment. Closer interaction between clinicians and laboratory personnel by means of request forms can improve the quality of services to patients.

Urinary tract infection (UTI) is increasingly rising in Bangladesh due to the development of resistance of causative pathogens against commonly prescribed antibiotics. Present study attempted to examine the prevalence of such uropathogens and their antibiogram profiles. Among 462 urine samples collected from patients with UTI, 100 were found to be culture positive. Escherichia coli (70%) was predominating, while Klebsiella spp. (11%) and Enterococcus spp. (6%) were also prevalent. About 96% uropathogens were sensitive against imipenem, and 75% against amikacin. The resistance rate of E. coli and Klebsiella spp. against ampicillin was 98.5 and 100%, respectively, and to cefotaxime, 84.3 and 72.8%, respectively. More than 80% resistance against these antibiotics was scored for other isolates. The frequency of drug resistance was found to be comparatively elevated in E. coli, Pseudomonas spp. and Proteus spp. Overall, the present investigation emphasized the need for routine screening of antibiotic resistance to promote effective medication against UTI.

Abstract Objectives The prevalence of ESBL-producing Escherichia coli (ESBL-E. coli) in community-acquired urinary tract infections (UTI) has been increasing worldwide since 2000, but with large geographical variations. The aim of this study was to determine whether the ESBL-E. coli rate in urine samples from individuals with community-acquired UTI was associated with the local socio-economic, environmental, agricultural and healthcare characteristics. Methods This was a cross-sectional study in western France using data on antibiotic susceptibility of E. coli isolated from urine samples of individuals with community-acquired UTI analysed in non-hospital laboratories from 2015 to 2017. The ESBL-E. coli rate was calculated for each laboratory. Data on socio-economic characteristics, human antibiotic consumption, hospital bed density, animal farming density and percentage of agricultural land and surface water were retrieved at the municipality level and aggregated by study area. Their association with ESBL-E. coli prevalence was quantified using multivariate linear regression models with a backward selection. Results From 358 291 E. coli isolates from urine samples tested in 92 laboratories, the mean ESBL-E. coli prevalence for the study period was 3.30%. In an adjusted model, the ESBL-E. coli rate was significantly (P < 0.05) and positively associated with the local percentage of people >65 years old, third-generation cephalosporin use (DDD/1000 inhabitants), number of hospital beds/km2, poultry density, pig density and percentage of agricultural land. Lower deprivation was associated with a higher ESBL-E. coli rate. Conclusions Several anthropogenic factors (primary care, hospitals and animal farming) are associated with the local ESBL-E. coli rate in community-acquired UTI. These results could contribute to improve risk management, including identification of at-risk patient groups.

Abstract Objectives To assess whether resistance estimates obtained from sentinel surveillance for antimicrobial resistance (AMR) in community-acquired urinary tract infections (UTIs) differ from routinely collected laboratory community UTI data. Methods All patients aged ≥18 years presenting to four sentinel general practices with a suspected UTI, from 13 November 2017 to 12 February 2018, were asked to provide urine specimens for culture and susceptibility. Specimens were processed at the local diagnostic laboratory. Antibiotic susceptibility testing was conducted using automated methods. We calculated the proportion of Escherichia coli isolates that were non-susceptible (according to contemporaneous EUCAST guidelines) to trimethoprim, nitrofurantoin, cefalexin, ciprofloxacin and amoxicillin/clavulanic acid, overall and by age group and sex, and compared this with routine estimates. Results Sentinel practices submitted 740 eligible specimens. The specimen submission rate had increased by 28 specimens per 1000 population per year (95% CI 21–35). Uropathogens were isolated from 23% (169/740) of specimens; 67% were E. coli (113/169). Non-susceptibility of E. coli to trimethoprim was 28.2% (95% CI 20.2–37.7) on sentinel surveillance (33.4%; 95% CI 29.5–37.6 on routine data) and to nitrofurantoin was 0.9% (95% CI 0–5.7) (1.5%; 95% CI 0.7–3.0 on routine data). Conclusions Routine laboratory data resulted in a small overestimation in resistance (although the difference was not statistically significant) and our findings suggest that it provides an adequate estimate of non-susceptibility to key antimicrobials in community-acquired UTIs in England. This study does not support the need for ongoing local sentinel surveillance.

Abstract Background E. coli is a leading cause of healthcare-associated infections; clonal group ST131, which has expanded worldwide with notable increased severity of infections, is commonly resistant to extended-spectrum cephalosporins (ESC) and fluoroquinolones (FQ). Herein, we relate ESC and FQ resistance profiles from CDC’s National Healthcare Safety Network (NHSN) with specific strain types from CDC laboratory surveillance collections. Methods NHSN isolate and antibiotic susceptibility testing data were collected from all E. coli associated with central line-associated bloodstream infections, catheter-associated urinary tract infections, ventilator-associated events, or surgical site infections from 2013–2017. Resistance was scored as non-susceptibility to at least one drug per class [susceptible (S); resistant (R)]. ESC and FQ susceptibilities and multilocus sequence types (ST) using the Achtman 7 loci scheme were determined for a contemporaneous set of E. coli isolates collected through CDC laboratory surveillance. Results Of 96,672 E. coli infections reported to NHSN, 13% were ESC-R/FQ-R, 23% ESC-S/FQ-R, 4% ESC-R/FQ-S, and 60% were ESC-S/FQ-S. Among 105 ESC-R/FQ-R and 21 ESC-S/FQ-R laboratory isolates, the majority (67.6% and 52.4%, respectively) were ST131, whereas of 38 ESC-R/FQ-S and 53 ESC-S/FQ-S isolates, ST131 was a minority (18.4% and 7.5%, respectively). The odds of an isolate being ST131 were 10.5 if FQ-R (P < 0.001), 3.4 if ESC-R (P < 0.001), and 6.0 if ESC-R/FQ-R (P < 0.001). Using the national distribution of resistance combinations from NHSN, and assuming static ST-resistance distribution, we can infer that ST131 was responsible for 25.8% (95% CI, 23.9%-27.6%) of all E.coli healthcare-associated infections in the United States in 2013–2017. Conclusion Molecular inferences generated by applying laboratory data to resistance signature data in reportable datasets may make national E. coli ST burden estimates possible. Further characterization of resistance combinations with strain type, infection rates, and clinical outcomes may inform targeted prevention strategies at the local/regional level.
