Management of urinary tract infection in patients with spinal cord injuries

System failure: Systemic inflammation following spinal cord injury

Spinal cord injury (SCI) affects hundreds of thousands of people in the United States, and while some effects of the injury are broadly recognized (deficits to locomotion, fine motor control, and quality of life), the systemic consequences of SCI are less well-known. The spinal cord regulates systemic immunological and visceral functions; this control is often disrupted by the injury, resulting in viscera including the gut, spleen, liver, bone marrow, and kidneys experiencing local tissue inflammation and physiological dysfunction. The extent of pathology depends on the injury level, severity, and time post-injury. In this review, we describe immunological and metabolic consequences of SCI across several organs. Since infection and metabolic disorders are primary reasons for reduced lifespan after SCI, it is imperative that research continues to focus on these deleterious aspects of SCI to improve life span and quality of life for individuals with SCI.

Factors associated with urinary tract infection in the early phase after performing intermittent catheterization in individuals with spinal cord injury: a retrospective study

Objectives

To investigate the occurrence rate of urinary tract infections (UTIs) in the early phase after performing intermittent catheterization (IC) and to explore the possible factors associated with UTIs after performing IC among people with spinal cord injury (SCI).

Setting

An inpatient rehabilitation department of a teaching hospital in China.

Design

Retrospective chart review.

Methods

A retrospective chart review was carried out for traumatic and non-traumatic SCI patients after performing IC during their inpatient stay. Demographic information, comorbidity of diabetes, urine analysis results before IC, method of IC (sterile or clean), use of bladder irrigation, cessation of IC and its reasons, and UTI events were collected.

Results

A total of 183 adult individuals were included, of which 60 (32.8%) of them were women. The median age was 49.0 years. The median time post-injury was 2 months. The overall occurrence rate of UTI after performing IC was 1.31 (95% confidence intervals: 0.96-1.77) events per 100 days. Sixty-nine (37.7%) patients discontinued IC during hospitalization, and UTIs were the leading reason for cessation (50.7%). Female sex, use of antibiotics for infections other than UTI, and use of bladder irrigation were found to be associated with a lower occurrence rate of UTI in the early phase after performing IC, with an odds ratio of 0.38 (p = 0.019), 0.20 (p = 0.022), and 0.24 (p < 0.001), respectively.

Conclusion

UTI after performing IC is prevalent among people with SCI. The study indicated that antibiotic prophylaxis and routine bladder irrigation might be associated with the reduction in UTI in the early phase after performing IC. Further research is needed to provide more evidence.

No adverse consequences associated with targeting clinical signs to initiate antimicrobial treatment of postoperative subclinical bacteriuria in dogs following surgical decompression of Hansen type I thoracolumbar disk herniation

OBJECTIVE

To describe the prevalence of postoperative bacteriuria, clinical course of subclinical bacteriuria in the absence of antimicrobial intervention, clinical signs of bacteriuria that trigger antimicrobial treatment, and outcomes for dogs with subclinical bacteriuria following surgical decompression of acute intervertebral disc herniation (IVDH) Hansen type I.

ANIMALS

Twenty client-owned dogs undergoing hemilaminectomy for acute (≤ 6 days) IVDH Hansen type I affecting the thoracolumbar spinal cord segments between August 2018 and January 2019.

PROCEDURES

In this prospective study, dogs were serially evaluated at presentation, hospital discharge, 2 weeks postoperatively, and between 4 and 6 weeks postoperatively. Dogs were monitored for clinical signs of bacteriuria, underwent laboratory monitoring (CBC, biochemical analyses, urinalysis, urine bacterial culture), and were scored for neurologic and urinary status. In the absence of clinical signs, bacteriuria was not treated with antimicrobials.

RESULTS

Four of the 18 dogs developed bacteriuria without clinical signs 4 days to 4 to 6 weeks after surgery. In all 4 dogs, bacteriuria resulted in lower urinary tract signs 13 to 26 weeks postoperatively. No dogs had evidence of systemic illness despite delaying antimicrobial treatment until clinical signs developed. New-onset incontinence was the only clinical sign in 3 dogs. All bacterial isolates had wide antimicrobial susceptibility. Bacteriuria and clinical signs resolved with beta-lactam antimicrobial treatment.

CLINICAL RELEVANCE

Postoperative bacteriuria occurs in some dogs with IVDH Hansen type I and, when present, may lead to clinical signs over time. Clinical signs of bacteriuria may be limited to new-onset urinary incontinence, inappropriate urination, or both. Delaying antimicrobial treatment until clinical signs of bacteriuria developed did not result in adverse consequences or systemic illness.

Pregnancy, delivery, and neonatal outcomes among women with spinal cord injury in Sweden 1997-2015: A population-based cohort study

INTRODUCTION

The aim of this study was to describe the rate of pregnancy in spinal cord injured women in Sweden as well as pregnancy, delivery, and neonatal outcomes.

MATERIAL AND METHODS

This study was based on data from the Swedish Medical Birth Register and the National Patient Register. The study population included women with spinal cord injury who gave birth in Sweden during the period 1997 to 2015. The general population was used as reference and included all non-spinal cord injured patients who gave birth during the same period of time.

RESULTS

In the spinal cord injury group, 109 births were identified. Eighty-nine (82%) of them were among paraplegic women and 20 (18%) were among tetraplegic women. Women with spinal cord injury in our study population had urinary tract infections during pregnancy in five cases (5%) and anemia during pregnancy in nine cases (8%), compared with 0.2% and 4%, respectively, in the general population. Compared with the general population more deliveries were induced in the study population, 18 (17%) in the spinal cord injury group and 12% in the general population. Vaginal delivery was achieved in 52 (48%) of the births with 42 of them (39%) being non-instrumental and 10 (9%) being instrumental vaginal deliveries. Elective cesarean section rate was 34% (n = 37). Sixteen infants (15%) were born preterm (gestational week <37). We found an overall low rate of pregnancy and delivery complications.

CONCLUSIONS

Our results show predominantly favorable outcomes of pregnancy and delivery in women with spinal cord injury as well as their infants. These results are in concordance with previous research.

Incidence of urinary tract infection following initiation of intermittent catheterization among patients with recent spinal cord injury in Germany and the Netherlands

Objective: To assess incidence of urinary tract infection (UTI) among patients with recent spinal cord injury (SCI) who initiated intermittent catheterization (IC).Design: Retrospective chart review.Setting: Two European SCI rehabilitation centers.Participants: Seventy-three consecutive patients with recent SCI who initiated IC.Outcome measures: Incidence of UTI, using six different definitions, each based on microbiology ± symptomatology ± mention of UTI . Rates were expressed in terms of numbers of UTIs per 100 patient-months (PMs). Attention was focused on first-noted UTI during the three-month follow-up, as assessed with each of the six definitions.Results: Fifty-eight percent of patients (n = 33) met ≥1 definitions for UTI during follow-up (rate: 31.5 UTIs per 100 PMs), ranging from 14% (5.3 per 100 PMs; definition requiring bacteriuria, pyuria, and presence of symptoms) to 45% (22.7 per 100 PMs; definition requiring "mention of UTI"). Ten cases were identified using the definition that required bacteriuria, pyuria, and symptoms, whereas definitions that required bacteriuria and either pyuria or symptoms resulted in the identification of 20-25 cases. Median time to UTI ranged from 42 days ("mention of UTI") to 81 days (definition requiring bacteriuria and ≥100 leukocytes/mm3).Conclusion: Depending on definition, 14% to 45% of patients with recent SCI experience UTI within three months of initiating IC. Definitions requiring bacteriuria and either pyuria or symptoms consistently identified about twice as many cases as those that required all three conditions. Standardizing definitions may help improve detection, treatment, and prevention of UTI within this vulnerable population.

Trans-Spinal Electrical Stimulation Therapy for Functional Rehabilitation after Spinal Cord Injury: Review

Spinal cord injury (SCI) is one of the most debilitating injuries in the world. Complications after SCI, such as respiratory issues, bowel/bladder incontinency, pressure ulcers, autonomic dysreflexia, spasticity, pain, etc., lead to immense suffering, a remarkable reduction in life expectancy, and even premature death. Traditional rehabilitations for people with SCI are often insignificant or ineffective due to the severity and complexity of the injury. However, the recent development of noninvasive electrical neuromodulation treatments to the spinal cord have shed a ray of hope for these individuals to regain some of their lost functions, a reduction in secondary complications, and an improvement in their life quality. For this review, 250 articles were screened and about 150 were included to summarize the two most promising noninvasive spinal cord electrical stimulation methods of SCI rehabilitation treatment, namely, trans-spinal direct current stimulation (tsDCS) and trans-spinal pulsed current stimulation (tsPCS). Both treatments have demonstrated good success in not only improving the sensorimotor function, but also autonomic functions. Due to the noninvasive nature and lower costs of these treatments, in the coming years, we expect these treatments to be integrated into regular rehabilitation therapies worldwide.

Multidrug-resistant bacteria in urine culture among patients with spinal cord injury and disorder: Time to first detection and analysis of risk factors

STUDY DESIGN

Retrospective cohort study.

OBJECTIVES

The aim of this study was to assess the time to first detection of multidrug-resistant bacteria (MDRB) in urine culture and identify risk factors associated with the first detection of MDRB (1^st MDRB).

SETTING

Spinal Care Ward and Department of Microbiology, Regional Hospital Liberec a.s., Liberec, Czech Republic.

METHOD

We cultured urine samples from patients in the acute phase of spinal cord injury or disorder (SCI/D). Multidrug resistance (MDR) was defined as acquired nonsusceptibility to at least one agent from three or more antimicrobial categories. Multivariate logistic regression was used to assess the association of bladder management, broad-spectrum antibiotic exposure, mechanical ventilation, pressure ulcers, positive urine culture on admission, and other risk factors with 1^st MDRB. We used only the first urine culture with MDRB for evaluation.

RESULTS

A total of 655 urine cultures from 246 individuals were evaluated, and 829 isolates were obtained. The MDRB prevalence among all isolates was 40.2%. MDRB was detected in 146 (59.3%) patients for the first time, and 76.0% of these isolates were from patients with asymptomatic bacteriuria. The median time to 1^st MDRB was 37 days (95% CI, 33-41). According to multivariate logistic regression, 1^st MDRB was associated with bladder management with urethral or suprapubic catheterization (OR: 2.8, 95% CI, 1.1-7.2).

CONCLUSION

The prevalence of infections caused by MDRB was high among the SCI/D population, with three-quarters from patients with asymptomatic bacteriuria. Bladder management with an indwelling catheter is associated with an increased risk of 1^st MDRB.

Management of Acute Traumatic Spinal Cord Injury: A Review of the Literature

Traumatic spinal cord injury (TSCI) is a debilitating disease that poses significant functional and economic burden on both the individual and societal levels. Prognosis is dependent on the extent of the spinal injury and the severity of neurological dysfunction. If not treated rapidly, patients with TSCI can suffer further secondary damage and experience escalating disability and complications. It is important to quickly assess the patient to identify the location and severity of injury to make a decision to pursue a surgical and/or conservative management. However, there are many conditions that factor into the management of TSCI patients, ranging from the initial presentation of the patient to long-term care for optimal recovery. Here, we provide a comprehensive review of the etiologies of spinal cord injury and the complications that may arise, and present an algorithm to aid in the management of TSCI.

Safety of Every-Other-Day Fasting in the Treatment of Spinal Cord Injury: A Randomized Controlled Trial

ABSTRACT

Every-other-day fasting is effective for a variety of major human diseases, but the safety of these interventions is uncertain for patients with spinal cord injury. A randomized controlled study was conducted to investigate the safety of every-other-day fasting in patients with spinal cord injury. Participants who met the diagnostic inclusion and exclusion criteria were randomly divided into the control and every-other-day fasting groups. In the every-other-day fasting group, fasting lasted from 09:00 p.m. on day 1 to 06:00 p.m. on the following day (day 2). Dinner on day 2 was restricted to approximately 30% of the average daily calorie intake. The changes in plasma glucose were recorded daily for 2 days and every other day from the third day after every-other-day fasting intervention. The changes in albumin, prealbumin, plasma potassium, serum sodium, blood calcium, body weight, and body mass index were monitored at the baseline and at the end of the every-other-day fasting intervention. The results showed that compared with the control group, the mean blood glucose levels were significantly decreased from the second week after every-other-day fasting intervention. The body weight of patients in the every-other-day fasting group was notably reduced compared with that at baseline, whereas in body mass index, no obvious differences were observed before and after treatment with every-other-day fasting. In general, every-other-day fasting could be considered as a safe approach for individuals with spinal cord injury.

The Stockholm Spinal Cord Uro Study: 3. Urodynamic characteristics in a regional prevalence group of persons with spinal cord injury and indications for improved follow-up

AIMS

Examine the outcome of urodynamic studies in a regional prevalence group of patients with traumatic spinal cord injury (SCI), explore relationships between urodynamic parameters and renal complications/other SCI-related dysfunctions, assess the role of urodynamics in SCI follow-up.

METHODS

In a cross-sectional study, 211 patients were included, who attended a yearly check-up and had urodynamics performed as part of the follow-up in addition to S-creatinine, S-cystatin-C, renal ultrasound, and a questionnaire regarding complications. Relationships between urodynamic parameters and renal complications/other SCI-related dysfunctions were explored by descriptive and comparative statistics.

RESULTS

Neurogenic detrusor overactivity (NDO) was found in 150, underactive/acontractile detrusor in 44, normal detrusor function in 17 patients. Maximum detrusor pressures during filling/voiding in NDO attained mean levels of >40 cm H₂O in 68% of patients and >25 cm H₂O in 83%. Reduced compliance of the bladder wall, cystometric bladder capacity <250 mL, and detrusor overactivity leakage during filling were associated with higher detrusor pressures. Detrusor overactivity during more than one-third of the filling phase was significantly related to signs of renal complications among patients with SCI duration 11-20 years. No significant relationships were found between other urodynamic parameters and renal/other SCI-related complications. Renal complications in underactive/acontractile and normal detrusor function co-varied with evidence of previous NDO and other co-morbidities which may negatively influence kidney function.

CONCLUSIONS

Maximum detrusor pressures during the filling/voiding phases attained high levels in a majority of patients. Detrusor overactivity during more than one-third of the filling phase was significantly related to signs of renal complications.

Clinical features and prognosis of COVID-19/SARS-CoV-2 infections in persons with spinal cord injury: a review of current literature

Study design

Focused literature review.

Objectives

Objective of the study was to perform a literature search and summarise the clinical features and prognosis of persons with spinal cord injury (SCI) infected with COVID-19 from the published articles.

Setting

India.

Methods

PubMed, CENTRAL and MEDLINE were systematically searched using specific keywords. The study assessed 2747 scientific studies involving COVID-19 and SCI for possible inclusion in a meta-analysis of SCI and SARS-COV-2. Studies involving persons with SCI who were tested positive for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in the nasopharyngeal or throat swab polymerase chain reaction were included.

Results

Out of 2747 articles, 11 articles (206 participants), including six case reports, were included in this review. Fever was the most frequently observed symptom of COVID-19 infection in the SCI population. C-reactive protein (CRP) and lymphocytopenia were common abnormal laboratory parameters. The most common radiological finding in COVID-19 infection was ground glass opacities in lung fields. Prophylactic/therapeutic anticoagulation was given in a significant number of SCI persons infected with COVID-19. Persons with SCI who were diagnosed early showed good outcomes.

Conclusions

Based on the few studies published on COVID-19 and SCI populations since 2019, this study determined fever, elevated CRP, lymphocytopenia and ground glass opacities, which indicated inflammation, compromised immune response, and lung edema, as the main clinical features of COVID-19 infection in SCI population. Though COVID-19 infection reported an increased number of deaths in few studies, a significant number of SCI populations with positive RT-PCR were treated successfully and discharged at home.

Asymptomatic bacteriuria among medical inpatients: Data from an Indian teaching hospital

Studies indicate that asymptomatic bacteriuria in medical inpatients is often inappropriately treated with antibiotics. We prospectively studied the proportion of asymptomatic bacteriuria among 200 positive urine cultures which were ordered in hospitalised medical inpatients of a teaching hospital in southern India. We used pre-defined criteria to classify patients as urinary tract infection and asymptomatic bacteriuria. Median age of patients was 53.5 (42-65) years, and 51% were male. In all, 157 (78.5%) patients had urinary tract infection (131 [66.5%] definite and 26 [13%] probable) and 43 (21.5%) had asymptomatic bacteriuria. In patients with asymptomatic bacteriuria, 18 (41.8%) received urinary tract infection-directed antibiotics; broad spectrum antibiotics were used in 10 (23%). Patients with asymptomatic bacteriuria were younger, more likely to be on a urinary catheter, had higher prevalence of chronic kidney disease and congestive cardiac failure and had lower prevalence of pyuria and lower total leucocyte counts. Urine cultures should be ordered only in indicated patients. Inappropriate antibiotic treatment in patients with asymptomatic bacteriuria should be avoided.

Secondary health conditions and disability among people with spinal cord injury: A prospective cohort study

Objective: To examine how secondary health conditions (SHCs) that develop early after a spinal cord injury (SCI) are related to disability over time.Design: Prospective cohort study.Setting: Two spinal units in New Zealand (Burwood Spinal Unit and Auckland Spinal Rehabilitation Unit).Participants: Between 2007 and 2009, 91 people participated in three telephone interviews approximately 6, 18, and 30 months after the occurrence of a SCI.Outcome measures: SHCs were measured using 14 items derived from the Secondary Complications Survey. Disability was measured using the 12-item World Health Organization Disability Assessment Schedule 2.0. Linear regression analyses were performed to investigate associations between SHCs at 6 months and disability at each assessment point.Results: The most prevalent SHCs were leg spasms, constipation, back pain, pain below the level of SCI, and shoulder pain. Constipation, urinary tract infection, and headaches at 6 months post-SCI were associated with significantly higher levels of disability at each subsequent follow-up, independent of age, sex and SCI impairment. Back pain, and pain below the SCI, at 6 months were associated with significantly greater disability at 18 months, and difficulty coughing at 6 months was associated with significantly greater disability at 30 months.Conclusion: The experience of specific SHCs in the first 6 months after an SCI is related to greater long-term disability. In order to reduce the disability burden of people with SCI, efforts should be directed toward early prevention of these SHCs.

Comparing the causes, circumstances and consequences of falls across mobility statuses among individuals with spinal cord injury: A secondary analysis

OBJECTIVE

To compare the occurrence of falls and fall-related injuries, and the circumstances of falls among individuals with spinal cord injury (SCI) who ambulate full-time, use a wheelchair full-time and ambulate part-time.

DESIGN

A secondary analysis.

SETTING

Community.

PARTICIPANTS

Adults with SCI.

INTERVENTION

None.

OUTCOME MEASURES

The occurrence and circumstances of falls and fall-related injuries were tracked over six-months using a survey. Participants were grouped by mobility and fall status. A chi-square test compared the occurrence of falls and fall-related injuries, and the time and location of falls, and a negative binomial regression was used to predict the likelihood of falls by mobility status. Kaplan-Meier analysis was used to determine differences in the time to first fall based on mobility status. Group characteristics and causes of falls were described.

RESULTS

Data from individuals who ambulated full-time (n = 30), used a wheelchair full-time (n = 27) and ambulated part-time (n = 8) were analyzed. Mobility status was a significant predictor of falls (P < 0.01); individuals who used a wheelchair full-time had a third of the likelihood of falling than those who ambulated full-time (P < 0.01). Type of fall-related injuries differed by mobility status. Those who ambulated full-time fell more in the daytime (P < 0.01). Individuals who ambulated full-time and part-time commonly fell while walking due to poor balance, and their legs giving out, respectively. Those who used a wheelchair full-time typically fell while transferring when rushed.

CONCLUSION

Mobility status influences the likelihood and circumstances of falls. Mobility status should be considered when planning fall prevention education/training for individuals with SCI.

Association between ureteric stent dwell time and urinary tract infection

BACKGROUND

Ureteric stone obstruction commonly presents to the emergency department, with definitive management often involving ureteroscopy and laser lithotripsy. Insertion of a ureteric stent prior to staged lithotripsy is commonly performed in the public healthcare system. Foreign bodies in the urinary tract are also known to increase urinary tract infection (UTI) risk. This study aims to evaluate the association between stent dwell time and UTI prior to lithotripsy.

METHODS

The medical records of all patients who were treated for ureteric stones with initial stent insertion and staged lithotripsy, from 1 January 2018 to 30 June 2019 at a single tertiary centre, by eight urologists were retrospectively reviewed. Demographic features, disease factors and urine culture data were collected and analysed.

RESULTS

Of the 172 patients (median age 56.7 years) identified, one-third had a positive pre-stent urine culture. Twenty-three percent had a positive pre-lithotripsy urine culture with 38% of females compared with 15% of males having a positive culture (P = 0.001). Only 4.3% of patients had a pre-lithotripsy UTI when the stent dwell time was less than 1 month compared with 26.2% when ureteric stents were in situ for longer than 1 month (P = 0.021). The correlation between ureteric stent dwell time and pre-lithotripsy UTI was not linear. Patient comorbidities, stone size, burden and location were not statistically correlated to pre-lithotripsy UTI.

CONCLUSION

In delayed two-staged surgical management of acute urolithiasis, optimal ureteric stent dwell time is less than 1 month to reduce pre-lithotripsy UTI. Female gender is an independent risk factor for pre-lithotripsy UTI.

High risk of Clostridium difficile infection among spinal cord injured patients after the use of antibiotics commonly used to treat urinary tract infections

AIM

To characterize the use of common urinary tract infections (UTI)-relevant antibiotics after an SCI and determine the risk of Clostridium difficile infection (CDI) from these antibiotics.

METHODS

We used routinely collected data from Ontario (Canada) to conduct a retrospective, cohort study. We identified people >18 years of age with a traumatic SCI between April 2003 and March 2017. The primary exposure was an outpatient UTI-relevant antibiotic prescription during our observation period, and the primary outcome was evidence of a CDI. An adjusted cox proportional hazards model was used, and antibiotic exposure was modeled as a categorical, time-varying variable based on whether the patient likely had a UTI or not.

RESULTS

We identified 2528 people with SCI; 1642 (65%) were exposed at least once to an antibiotic of interest. The most commonly prescribed UTI-relevant antibiotic was fluoroquinolone (34%). Most patients did not have investigations for a UTI before the use of any of the different antibiotic classes. A small number of patients (5%) used chronic (>3 months) UTI-relevant antibiotics. The overall proportion of patients diagnosed with CDI was 7.4% (9.3/10 000 patient-days). The adjusted hazard ratio for CDI within 30 days was 3.5 (95% confidence interval, 1.9-6.7, p < .01) if they were exposed to a UTI-relevant antibiotic likely associated with a UTI, which was similar to the risk from UTI-relevant antibiotics which may not have been for a UTI.

CONCLUSIONS

The rate of CDI is high in this population and outpatient antibiotics that are commonly used for UTIs are a significant risk factor for CDI.

COVID-19: Screening and triage challenges in people with disability due to Spinal Cord Injury

An outbreak of a novel coronavirus disease (COVID-19) that emerged in the Chinese city of Wuhan has rapidly become a global public health pandemic. As of March 2020, the Centers for Disease Control and Prevention (CDC) has described priority levels for testing patients with suspected COVID-19 and information on when to seek medical attention. However, there is a paucity of further guidance for people with spinal cord injury (SCI) who may not present with typical symptoms of COVID-19 due to altered physiology. This may pose challenges with surveillance, risk stratification, and initial management of this vulnerable population. In this point-counterpoint discussion, we outline important differences in presentation along with COVID-19 cases co-morbid with SCI.

Satisfaction with access and quality of healthcare services for people with spinal cord injury living in the community

Objective: To identify barriers to access healthcare services and reveal determinants of satisfaction with healthcare services in people with chronic spinal cord injury (SCI).Design: Cross-sectional survey.Setting: Community setting in Switzerland.Participants: People with chronic SCI.Interventions: Non-applicable.Outcome Measures: Questionnaire-based evaluation of availability and quality of healthcare services for secondary health conditions, satisfaction with fulfillment of healthcare needs, and preference for care from a hypothetical service provider with limited specialized SCI care expertise but in close proximity over comprehensive care from an existing specialized SCI center located at a greater distance.Results: Close to three-quarter of participants (70%) indicated satisfaction with healthcare services received for SCI related health conditions. Elderly individuals (61+ years old) rated the availability and quality of healthcare 6% to 11% higher than younger individuals. The perceived fulfillment of healthcare needs was lower in people with incomplete paraplegia (odds ratio (OR) 2.11, 95%-credibility interval (CI) 1.18-3.84), chronic pain (OR 1.85, CI 1.12-3.08), insufficient access to long distance transportation (OR 5.81, CI 2.74-12.82), and longer travel distances to specialized SCI centers.Conclusion: Perceived inadequateness of access to healthcare services was partly related to transportation barriers, suggesting that outreach services or support with transportation are possible solutions. People with incomplete paralysis and pain consistently rated the fulfillment of care needs associated with SCI less favorably, pointing to the need for enhanced advocacy for this vulnerable groups.

Conception and development of Urinary Tract Infection indicators to advance the quality of spinal cord injury rehabilitation: SCI-High Project

Context: Urinary tract infections (UTI) are the most frequent secondary health condition following spinal cord injury or disease (SCI/D) that adversely impact overall health and quality of life, and often result in rehabilitation service interruptions, emergency department visits, and urinary sepsis. Methods: Experts in Urohealth and/or UTI recognition and management and the SCI-High Project Team used a combination of evidence synthesis and consensus methods for developing the UTI indicators. A systematic search and a Driver diagram analysis were applied to identify key factors influencing UTI. This Driver diagram guided the UTI Working Group when defining the construct, specifying the aim for the UTI SCI/D quality indicators, and developing the UTI diagnostic checklist and fever definition. Results: The structure indicator was the proportion of patients with a health care professional (i.e. family physician or urologist) able to follow-up with the patient regarding urine culture and sensitivity results within 48-72 h of collection. The Working Group knowingly adopted a single checklist for UTI diagnosis, recognizing the stark contrast in the complexity of diagnosis in acute versus community settings. The process indicator is the proportion of SCI/D rehabilitation inpatients with UTI as defined by the UTI diagnostic checklist. The outcome indicator is the proportion of SCI/D rehabilitation inpatients with inappropriate antibiotic prescription. Conclusion: UTI can be diagnosed using the developed symptoms and signs checklist. These structure, process, and outcome quality indicators will ultimately reduce inappropriate antibiotic therapy for UTI and the rising incidence of antibiotic resistance among community-dwelling individuals with chronic SCI/D.

Evaluation of functional outcomes in traumatic spinal cord injury with rehabilitation-acquired urinary tract infections: A retrospective study

OBJECTIVE

The objective of this study was to evaluate the impact of urinary tract infections (UTIs) acquired during acute inpatient traumatic Spinal Cord Injury (tSCI) rehabilitation on Functional Independence Measure (FIM) gains.

DESIGN

Retrospective chart review of consecutive patients with tSCI admitted to an acute rehabilitation facility from 2007-2012. The primary outcome was FIM scores and the association with UTI.

RESULTS

The sample included 110 patients and 70 acquired UTIs. No demographic differences were observed between groups with and without UTI. Those with UTIs had significantly lower FIM motor scores, on admission, discharge, and gain, as well as lower FIM efficiency and longer lengths of stay compared to those without a UTI. Recurrence of UTI was associated with increased length of stay, but did not impact FIM motor gains.

CONCLUSIONS

There was a statistically significant correlation between acquired UTIs and lower FIM motor scores on admission, gain, and discharge in tSCI rehabilitation. The correlation of UTI and decreased FIM gains are similar to other neurorehabilitation populations with UTI occurrence. UTIs are an important negative variable when measuring functional outcomes in rehabilitation. Further prospective studies should be performed to investigate this correlation.

National Survey of Bladder and Gastrointestinal Dysfunction in People with Spinal Cord Injury

Small-scale studies indicate that spinal cord injury (SCI) may lead to significant gastrointestinal and bladder dysfunction. However, how the prevalence of chronic disease related to these dysfunctions compares with non-SCI individuals and whether there are robust relationships to level and severity of injury are still unclear. Here, our goal was to provide high-level evidence on the association between bladder and gastrointestinal dysfunction and SCI using population-level data from the Canadian Community Health Survey (CCHS) and the SCI Community Survey. Data from more than 60,000 individuals in the 2010 CCHS and 1500 individuals with SCI from the SCI Community Survey were analyzed. We used bi-variable and multi-variable logistic regression to examine relationships between explanatory and outcome variables. We found that SCI was associated with increased odds of urinary incontinence (adjusted odds ratio [aOR] = 5.0, 95% confidence interval [CI]: 3.4-7.1), bowel disorders (aOR = 2.3, CI: 1.5-3.4), as well as gastric ulcers (aOR: 3.3, CI: 2.1-4.8), even after adjusting for key confounding variables. Additionally, we found that complete SCI was associated with increased odds of urinary tract infections (aOR = 2.0, CI: 1.6-2.5) and bowel incontinence (aOR = 2.1, CI: 1.7-2.6). Individuals with SCI are at increased odds for having bladder and gastrointestinal dysfunction, certain aspects of which are dependent on the level and severity of injury. Targeted intervention and prevention strategies to manage bladder and bowel problems after SCI should be a priority for both caregivers and policy makers.

The relationship of seasonality and the increase in urinary tract infections among hospitalized patients with spinal cord injury

BACKGROUND

Urinary tract infection (UTI) is the most frequent complication in patients who have spinal cord injury (SCI). The occurrence rate of UTI in this type of hospitalized patients was correlated to seasonality, age, and gender.

METHODS

Patients hospitalized during the 4-year study period with underlying SCI were identified from Taiwan's National Health Insurance Research Database. Patients with a discharge diagnosis of UTI were identified as those with SCI and UTI; they were divided into the following four age groups: <18 years, 18 to 44 years, 45 to 64 years, and ≥65 years. The gender, monthly number of cases, major complication rate, seasonal differences, and odds ratios (ORs) of associated factors were analyzed.

RESULTS

Data of 30 149 hospitalized patients diagnosed with SCI were retrieved. SCI and UTI were diagnosed in 3405 (11.3%) patients, of them 2296 were males (67.4%) and 1109 were females (32.6%). The UTI occurrence rate in hospitalized SCI patients was higher in males (11.8%) than in females (10.4%) (OR: 1.24; 95% CI: 1.15-1.34); it was highest in the ≥65-year-old age group (12.8%) and lowest in the <18-year-old age group (5.8%) (OR: 2.51; 95% CI: 1.83-3.44). The UTI occurrence rate varied from 7% to 18%, and it was highest in the summer (13.0% ± 2.6%) and lowest in the winter (10.2% ± 1.9%) (OR: 1.27; 95% CI: 1.15-1.40). Acute pyelonephritis was the most common complication in SCI and UTI cases.

CONCLUSION

The mean occurrence rate of UTI in hospitalized SCI patients was 11.3%; it was higher in males, in patients aged ≥65 years, and in the summer. Therefore, physicians should pay attention to the occurrence of UTI in aged male patients with SCI, especially in the summer.

Urinary tract infections in patients with neurogenic bladder

Urinary tract infections (UTIs) in patients with neurogenic bladder are a major public health issue due to their high incidence and major consequences. Despite their frequency and potential severity, their physiopathology and management are poorly known. We provide a narrative literature review on the epidemiology, physiopathology, diagnostic criteria, microbiology, antimicrobial management, and prevention. UTIs among patients with neurogenic bladder are associated with high morbidity and healthcare utilization. Risk factors for UTI among this population are: indwelling catheter, urinary stasis, high bladder pressure, and bladder stones. Their diagnosis is a major challenge as clinical signs are often non-specific and rare. A urinary sample should be analyzed in appropriate conditions before any antibiotic prescription. According to most guidelines, a bacterial threshold≥103CFU/ml associated with symptoms is acceptable to define UTI in patients with neurogenic bladder. The management of acute symptomatic UTI is not evidence-based. A management with a single agent and a short antibiotic treatment of 10 days or less seems effective. Antibiotic selection should be based on the patient's resistance patterns. Asymptomatic bacteriuria should not be treated to avoid the emergence of bacterial resistance. Regarding preventive measures, use of clean intermittent catheterization, intravesical botulinum toxin injection, and prevention using antibiotic cycling are effective. Bacterial interference is promising but randomized controlled trials are needed. Large ongoing cohorts and randomized controlled trials should soon provide more evidence-based data.

Patient subjective assessment of urinary tract infection frequency and severity is associated with bladder management method in spinal cord injury

STUDY DESIGN

The Neurogenic Bladder Research Group (NBRG) registry is a multicenter prospective observational study. This manuscript is retrospective based on a cross-sectional survey.

OBJECTIVES

To assess patient subjective assessment of urinary tract infection (UTI) frequency and severity are associated with the degree of use of catheters or incontinence products.

SETTING

Multiple hospitals across the United States.

METHODS

Eligibility included: age > 18 years and acquired SCI. Over 1.5 years, 1479 eligible participants were enrolled. We excluded those with surgical reconstruction or diversion of the bladder. In total, 1282 participants were grouped by bladder management: (1) indwelling catheter (IDC), (2) clean intermittent catheterization (CIC), (3) external devices (pads/condom), and (4) volitional voiding (Void). UTI frequency was classified as 0, 1-3, 4-6, or > 6 over the prior year. UTI severity was determined by hospitalization for UTI in the prior year. Multivariate regression compared these factors across groups.

RESULTS

UTIs were least frequent in Void followed by pads/condom, CIC, and IDC (all p ≤ 0.001). UTI severity followed a similar pattern. Controlling for covariates, the adjusted odds of UTI frequency (Void = reference) were 2.28 (1.38-3.76) for pads/condom, 3.42 (2.25-5.18) for CIC, and 4.3 (2.59-6.70) for IDC (all p ≤ 0.001).

CONCLUSIONS

Patient subjective assessment of UTI frequency is highest with IDC, followed by CIC, pads/condom, and lowest with spontaneous voiding. The odds of hospitalization for UTI were three times higher for IDC than spontaneous voiding. UTI risk should be considered when counseling patients about bladder management options. These associations do not imply causation but warrant further investigation in a prospective manner.

Probiotics [LGG-BB12 or RC14-GR1] versus placebo as prophylaxis for urinary tract infection in persons with spinal cord injury [ProSCIUTTU]: a randomised controlled trial

STUDY DESIGN

Randomised double-blind factorial-design placebo-controlled trial.

OBJECTIVE

Urinary tract infections (UTIs) are common in people with spinal cord injury (SCI). UTIs are increasingly difficult to treat due to emergence of multi-resistant organisms. Probiotics are efficacious in preventing UTIs in post-menopausal women. We aimed to determine whether probiotic therapy with Lactobacillus reuteri RC-14+Lactobacillus GR-1 (RC14-GR1) and/or Lactobacillus rhamnosus GG+Bifidobacterium BB-12 (LGG-BB12) are effective in preventing UTI in people with SCI.

SETTING

Spinal units in New South Wales, Australia with their rural affiliations.

METHODS

We recruited 207 eligible participants with SCI and stable neurogenic bladder management. They were randomised to one of four arms: RC14-GR1+LGG-BB12, RC14-GR1+placebo, LGG-BB12+ placebo or double placebos for 6 months. Randomisation was stratified by bladder management type and inpatient or outpatient status. The primary outcome was time to occurrence of symptomatic UTI.

RESULTS

Analysis was based on intention to treat. Participants randomised to RC14-GR1 had a similar risk of UTI as those not on RC14-GR1 (HR 0.67; 95% CI: 0.39-1.18; P = 0.17) after allowing for pre-specified covariates. Participants randomised to LGG-BB12 also had a similar risk of UTI as those not on LGG-BB12 (HR 1.29; 95% CI: 0.74-2.25; P = 0.37). Multivariable post hoc survival analysis for RC14-GR1 only vs. the other three groups showed a potential protective effect (HR 0.46; 95% CI: 0.21-0.99; P = 0.03), but this result would need to be confirmed before clinical application.

CONCLUSION

In this RCT, there was no effect of RC14-GR1 or LGG-BB12 in preventing UTI in people with SCI.

Illness Among Paralympic Athletes: Epidemiology, Risk Markers, and Preventative Strategies

Paralympic athletes have unique preexisting medical conditions that predispose them to increased risk of illness, but data are limited to studies conducted during the last 3 Paralympic Games. This article reviews the epidemiology of illness (risk, patterns, and predictors) in Paralympic athletes and provides practical guidelines for illness prevention. The incidence rate of illness (per 1000 athlete-days) in Paralympic athletes is high in Summer (10.0-13.2) and Winter (18.7) Paralympic Games. The authors propose general and specific guidelines on preventative strategies regarding illness in these athletes.

Change in urodynamic pattern and incidence of urinary tract infection in patients with traumatic spinal cord injury practicing clean self-intermittent catheterization

Objective: To observe changes in cystometric parameters in individuals with spinal cord injury (SCI) with neurogenic bladder practicing clean intermittent self-catheterization (CIC) and incidence of urinary tract infection (UTI) in such patients.Design: Prospective, observational study.Setting: Tertiary Urban Rehabilitation Hospital.Participants: Persons with neurogenic bladder caused by traumatic SCI and practicing CIC.Interventions: Clinical evaluation, complete urine analysis, urine culture and sensitivity, ultrasonography of the abdomen and urodynamic study were evaluated at baseline and at follow-up (6 months to 1 year).Outcome Measures: Detrusor pattern, cystometric capacity, detrusor compliance, detrusor leak point pressure, residual urine, incidence of UTI.Results: Thirty-one participants were included in the study. The baseline cystometric study showed that 15 had overactive detrusor and 16 had detrusor areflexia. The mean cystometric capacity decreased significantly between baseline and follow-up in both the groups but remained within the normal threshold limit, decline being more marked in the overactive detrusor group, who also had more marked decrease in compliance. Mean detrusor leak point pressure was below 40 cm H₂O in all participants in both groups at baseline and follow-up. Mean residual urine improved at follow-up in both groups. Incidence of UTI was 2.29 episodes per patient per year, and more frequent in the overactive detrusor group. Escherichia coli was the causative agent in 45%.Conclusion: The cystometric capacity and compliance decreased significantly though patients were doing regular CIC and managed on antimuscarinics for detrusor overactivity (DO). UTI is more common in individuals with SCI with DO and E. coli is the most common cause of UTI.

Bladder emptying method is the primary determinant of urinary tract infections in patients with spinal cord injury: results from a prospective rehabilitation cohort study

OBJECTIVE

To understand the occurrence of and risk factors for urinary tract infections (UTIs) in patients with spinal cord injury (SCI) undergoing specialized SCI rehabilitation in Switzerland.

PATIENTS AND METHODS

This study used data collected from 369 patients, who participated in a nationwide rehabilitation cohort for SCI in Switzerland between 2013 and 2017. Information on UTIs as well as their potential determinants, including demographics, lesion characteristics, and time-updated data on functional independence and bladder management, was used. Multivariable regression methods were applied to perform a time-updated evaluation of determinants of UTI risk.

RESULTS

The crude incidence rate (IR) of UTIs was 0.55 UTIs per 100 person-days (95% confidence interval [CI] 0.49-0.62), the cumulative IR was 43%, and the median length of stay was 122 days. The bladder emptying method at discharge was largely determined by 28 days after admission. Among those using indwelling or assisted intermittent catheterization (IC), the likelihood of self-IC at discharge was positively related to the level of self-care independence, negatively related to age at injury, and lower in women than men. Catheter users consistently had higher adjusted IRs for UTI than spontaneous voiders. The IR ratios were: indwelling catheter: 5.97 (95% CI 2.63-13.57); assisted IC: 6.05 (95% CI 2.63-13.94); self-IC: 5.16 (95% CI 2.31-11.52); test for differences across catheter groups: P = 0.82. Lesion severity and previous UTI had additional but smaller effect sizes.

CONCLUSIONS

Bladder emptying method was identified as the main risk factor for UTI in patients with SCI. As spontaneous voiders had the lowest UTI rate, further research is warranted to reduce voiding dysfunction, for instance using neuromodulation procedures.

Describing Functioning in People Living With Spinal Cord Injury in Switzerland: A Graphical Modeling Approach

OBJECTIVE

To describe functioning in people living with spinal cord injuries (SCI) in Switzerland.

DESIGN

Secondary analysis of cross-sectional survey data.

SETTING

Community, Switzerland.

PARTICIPANTS

Individuals (N=1549) 16 years of age or older with a history of traumatic or nontraumatic SCI and permanently residing in Switzerland.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Functioning was operationalized through 4 domains: (1) impairments in body functions; (2) impairments in mental functions; (3) independence in performing activities; and (4) performance problems in participation.

RESULTS

Univariate analysis indicated a high prevalence of problems in 5 areas: (1) housework; (2) climbing stairs; (3) tiredness; (4) spasticity; and (5) chronic pain. Graphical modeling showed a strong association among the four domains of functioning. Moreover, we found that the differences in the dependence structures were significant between the paraplegia SCI population and the tetraplegia SCI population.

CONCLUSIONS

This study is a first study in the epidemiology of functioning of people living with SCI in Switzerland. Using univariate and graphical modeling approaches, we proposed an empirical foundation for developing hypotheses on functioning in each domain and category that could inform health systems on people's health needs.

Enhancing quality practice for prevention and diagnosis of urinary tract infection during inpatient spinal cord rehabilitation

OBJECTIVES

To reduce the incidence of Urinary Tract Infection (UTI) in subacute SCI individuals admitted for tertiary inpatient rehabilitation.

DESIGN

A quality improvement team was assembled to improve UTI prevention/diagnosis. To plan data collection, UTI-related factors were mapped in an Ishikawa (fishbone) driver diagram. Data including patient demographics, presence and frequency of signs and/or symptoms of UTI and antibiotic initiation from August to December 2015 were recorded. Sensitivity, Specificity, Positive and Negative Predictive Values (PPV, NPV), and Likelihood Ratios (LR) were calculated for each sign and symptom.

SETTING

Tertiary SCI Rehabilitation Results: Among 55 inpatients with subacute SCI who had signs/symptoms prompting urine culture and sensitivity (C&S), 32 (58.18%) were diagnosed with a UTI. The most frequent symptoms were foul smelling urine (41%), change in urine color (31%), and incontinence (25%), and the most common sign was fever (34%). Most UTIs (81%) occurred among individuals using Clean Intermittent Catheterization (CIC), with 46% of catheterizations performed by nurses. Foul smelling urine had the highest sensitivity (0.50, 95% CI: 0.31-0.69), and new incontinence had the highest specificity (0.88, 95% CI: 0.69-0.97) for UTI diagnosis. The highest PPV belonged to the cloudy urine (0.71, 95% CI: 0.42-0.92). The combination of cloudy and foul smelling urine increased the PPV to 78% (95% CI: (0.40-0.97).

CONCLUSIONS

The concurrent presence of cloudy and foul smelling urine is predicted of UTI diagnosis inpatients tertiary setting. SCI inpatients are susceptible to UTI when learning CIC technique from nurses.

The Frequency and Clinical Implications of Bacteriuria in Chronically Paralyzed Dogs

Background

Paralysis is a known risk factor for urinary tract infections (UTI), sepsis, and death in paralyzed people, but there are no data available on diagnostic criteria for UTI versus bacteriuria, their frequency, or clinical implications in chronically paralyzed dogs.

Hypothesis/Objectives

That chronically paralyzed dogs suffer frequent bacteriuria causing reduced duration of survival. We documented the frequency of bacteriuria, associated clinical signs, and survival rate in chronically paralyzed dogs.

Animals

Forty‐seven client‐owned dogs paralyzed with no pelvic limb pain perception for >3 months and at least one urine culture (UC) performed.

Methods

Retrospective, observational study. Medical records of dogs meeting inclusion criteria were reviewed for results of UC, urinalysis, and clinical signs. Outcome was compared between dogs with and without bacteriuria.

Results

Thirty‐five of 47 dogs had at least 1 positive UC, and 13 had recurrent bacteriuria. Rectal temperature and urinalysis results were extracted from records. Fever was present at time of UC in 5 of 68 observations, 2 with and 3 without bacteriuria. Pyuria was significantly associated with positive cultures (P < 0.001), cloudiness was not (P = 0.076). Survival data in 35 dogs (8 dead) showed no association between bacteriuria and survival (P = 0.69).

Conclusions and Clinical Importance

Bacteriuria is common in paralyzed dogs but does not cause fever; diagnostic criteria of UTI are unclear. We did not detect an association of bacteriuria with survival, but this needs further confirmation.

Intermittent catheter users' symptom identification, description and management of urinary tract infection: a qualitative study

OBJECTIVES

To elucidate the views of intermittent catheter (IC) users regarding urinary tract infection (UTI) symptom presentation, terminology for describing signs and symptoms, the cause of UTI and management strategies.

DESIGN

Qualitative study with semi-structured interviews. The transcribed text was analysed thematically.

SETTING

12 general practitioner (GP) surgeries in Hampshire and Dorset, UK.

PARTICIPANTS

A convenience sample of 30 IC users, aged over 18, using IC for at least 3 months who had at least one self-reported UTI since starting IC.

RESULTS

Participants reported a variety of signs and symptoms, such as urine cloudiness and smell, as indicators of UTI. The terms used often differed from those in the modified National Institute on Disability and Rehabilitation Research (NIDRR) symptom set. IC users had difficulty distinguishing possible UTI symptoms from those of their comorbidities. They expressed uncertainty about the cause of UTI, often attributing it to poor hygiene and lifestyle behaviours. Whereas some viewed UTI as an expected consequence of IC use that could be self-managed, others felt more concerned and were more reliant on their GP for support. A range of management strategies was described, including drinking more fluids, increased attention to personal hygiene and self-medicating with antibiotics.

CONCLUSIONS

There is uncertainty among IC users about UTI signs and symptoms and when to seek help. Individual accounts of UTI fitted generally within the modified NIDRR descriptors but adopted less technical and more 'lay' language. IC users' descriptions of UTI signs and symptoms can lack precision, owing partly to the presence of underlying health conditions. This, together with differing levels of concern about the need to seek help and self-medication with antibiotics, presents challenges for the GP. This study provides the basis for developing a self-help tool which may aid identification of UTI and enhance communication with healthcare professionals.

Recurrent urinary tract infections in patients with incomplete bladder emptying: is there a role for intravesical therapy?

The goal of this review article is to discuss the etiology of recurrent urinary tract infections (UTIs) in individuals with impaired bladder emptying, evaluate existing studies regarding UTI prevention strategies in this population, and explore the published experiences with intravesical therapy for the prevention and treatment of recurrent UTIs in patients performing clean intermittent catheterization (CIC). We will also describe the intravesical antibiotic protocol utilized at our institution.

New and developing diagnostic technologies for urinary tract infections

Timely and accurate identification and determination of the antimicrobial susceptibility of uropathogens is central to the management of UTIs. Urine dipsticks are fast and amenable to point-of-care testing, but do not have adequate diagnostic accuracy or provide microbiological diagnosis. Urine culture with antimicrobial susceptibility testing takes 2-3 days and requires a clinical laboratory. The common use of empirical antibiotics has contributed to the rise of multidrug-resistant organisms, reducing treatment options and increasing costs. In addition to improved antimicrobial stewardship and the development of new antimicrobials, novel diagnostics are needed for timely microbial identification and determination of antimicrobial susceptibilities. New diagnostic platforms, including nucleic acid tests and mass spectrometry, have been approved for clinical use and have improved the speed and accuracy of pathogen identification from primary cultures. Optimization for direct urine testing would reduce the time to diagnosis, yet these technologies do not provide comprehensive information on antimicrobial susceptibility. Emerging technologies including biosensors, microfluidics, and other integrated platforms could improve UTI diagnosis via direct pathogen detection from urine samples, rapid antimicrobial susceptibility testing, and point-of-care testing. Successful development and implementation of these technologies has the potential to usher in an era of precision medicine to improve patient care and public health.

The growing threat of carbapenem resistant enterobacteriaceae (CRE) within in-patient spinal rehabilitation units

This case report highlights the present threat and challenges with treatment and transmission of infections caused by carbepenem-resistant enterobacteriaceae (CRE) within in-patient spinal rehabilitation units. The setting is within the Spinal Cord Injury Unit, Royal North Shore Hospital, Sydney, Australia. We report the case of a 45-year-old female with T9 complete paraplegia who developed CRE urinary tract infection (UTI) and sepsis 1 month post injury while in an in-patient spinal rehabilitation unit. We describe the challenges in treatment with colistin, the implications of infection on her rehabilitation and challenges in containing the spread of CRE to other patients in the unit. We present our experience with the management of CRE bactaeraemia in a spinal rehabilitation unit and the enhanced importance of infection control and surveillance strategies required to successfully contain risk of transmission.

The reliability and validity of using the urine dipstick test by patient self-assessment for urinary tract infection screening in spinal cord injury patients

Aims:

The aim of this is to evaluate the reliability of the urine dipstick test by patients’ self-assessment for urinary tract infection (UTI) screening and to determine the validity of urine dipstick test.

Settings:

Rehabilitation Department, Srinagarind Hospital, Thailand.

Study Design:

A diagnostic study.

Subjects and Methods:

This study compared the urine dipstick test (index test) with the National Institute on Disability and Rehabilitation Research (NIDRR) criteria (gold standard test) in spinal cord injury (SCI) patients. The urine dipstick test informed positive and negative results. Besides the NIDRR criteria classified as UTI and no UTI. The interrater reliability was measured in the sense of Kappa whereas the validity of urine dipstick test was reported in terms of sensitivity, specificity, positive likelihood ratio (LR) (+LR), negative LR (−LR), positive predictive value (PPV), and negative predictive value (NPV).

Results:

Out of the 56 participants, the kappa of urine dipstick test for leukocyte esterase, nitrite, and combined leukocyte esterase and nitrite were 0.09, 0.21, and 0.52, respectively. The nitrite urine dipstick test showed the highest sensitivity (90%). The combined leukocyte esterase and nitrite urine dipstick test gave the highest specificity (87%), PPV (60%), NPV (93%), and +LR (5.63).

Conclusions:

The interrater reliability of combined leukocyte esterase and nitrite urine dipstick test was moderate agreement. The combined leukocyte esterase and nitrite urine dipstick test showed high level of both sensitivity and specificity. The combined leukocyte esterase and nitrite urine dipstick test should be promoted for patients’ self-assessment for UTI screening in SCI patients.

Management of febrile urinary tract infection among spinal cord injured patients

BACKGROUND

Urinary tract infection (UTI) among patients with neurogenic bladder is a major problem but its management is not well known. We studied the relationship between antibiotic regimen use and the cure rate of those infections among 112 patients with neurogenic bladder.

METHODS

We studied a retrospective cohort of febrile UTI among patients with neurogenic bladder. Drug selection was left to the discretion of the treating physicians, in accordance with current guidelines. Patients were divided into 3 groups according to antibiotic treatment duration (<10 days, between 10 and 15 days, and >15 days). We analysed clinical and microbiogical cure rate one month after the end of antibiotic treatment.

RESULTS

The three groups of patients were similar, especially in terms of drug treatment (equal distribution). The cure rates were not significantly different (71.4 %, 54.2 %, and 57.1 %, respectively; p = 0.34). Moreover, there was no difference in cure rate between mono and dual therapy (44 % for monotherapy vs. 40 % for dual therapy; p = 0.71).

CONCLUSION

This descriptive study supports the efficacy of antimicrobial treatment duration of less than 10 days and the use of monotherapy to treat febrile UTI among patients with neurogenic bladder. A randomized control trial is required to confirm these data.

Prevalence of and Risk Factors for Multidrug-Resistant Bacteria in Urine Cultures of Spinal Cord Injury Patients

Objective

To identify the prevalence of multidrug-resistant (MDR) bacteria and identify their specific risk factors in routine urine specimens of spinal cord injury (SCI) patients.

Methods

This study was designed in a retrospective manner, reviewing the medical records of SCI patients who were admitted to a specialized SCI unit between January 2001 and December 2013. Patients were investigated for age, gender, American Spinal Injury Association impairment scale, SCI level, duration after injury, bladder management method, and hospitalization history within four weeks prior to visiting our unit. The results of routine urine cultures including presence of MDR organisms were analyzed.

Results

Among the total 2,629 urine samples from the newly admitted SCI patients, significant bacteriuria was identified in 1,929 (73.4%), and MDR organisms were isolated in 29 (1.1%) cultures. There was an increasing trend of MDR organism prevalence from 2001 to 2013 (p<0.01). The isolation of MDR organisms in inpatients who were admitted for rehabilitation (1.3%) was significantly higher than it was among community-residing persons (0.2%) (p<0.05). By voiding method, patients who used a suprapubic indwelling catheter (3.3%) or a urethral indwelling catheter (2.6%) showed a higher rate of MDR organism isolation (p<0.05).

Conclusion

There was an increasing trend of MDR organism isolation in SCI patients. Inpatients and persons who used indwelling catheters showed a higher risk of MDR organism isolation.

Spontaneous thoracolumbar hematomyelia secondary to hemophilia B in a cat

Case summary

A 10-year-old neutered male domestic shorthair cat presented for evaluation of acute onset of paraplegia with loss of nociception and thoracolumbar spine hyperesthesia and no history of trauma. Activated partial thromboplastin time (aPTT) was markedly prolonged, and specific coagulation factor testing revealed a factor IX level of 4% of normal activity, confirming the presence of mild hemophilia B. Prior abnormal bleeding had occurred at the time of castration as a kitten, as well as with laceration to a toe. Advanced imaging, including computed tomography (CT) and magnetic resonance imaging (MRI) of the thoracolumbar spine, confirmed the presence of multifocal intradural and intramedullary spinal cord hemorrhage through demonstration of focal ring enhancement on CT and multifocal areas of signal void on gradient echo T2* images on MRI. Despite factor IX supplementation through the use of fresh frozen plasma transfusions and normalization of the aPTT time, the cat’s neurological status did not improve. Owing to repeated urinary tract infections, with increasing resistance to antibiotic therapy, the cat was ultimately euthanized. Post-mortem examination showed no evidence of another underlying primary pathology for the hematomyelia.

Relevance and novel information

To our knowledge, this case demonstrates the first reported occurrence of spontaneous hematomyelia secondary to hemophilia B in a cat.

Abdominal strength in voiding cystometry: a risk factor for recurrent urinary tract infections in women

INTRODUCTION AND HYPOTHESIS

Recurrent urinary tract infections are a common condition in women. The aim of this study is the evaluation of lower urinary tract dysfunctions that are risk factors for recurrent urinary tract infections in women.

METHODS

We conducted a case-control study in 49 women with recurrent urinary tract infections (rUTIs) and 49 control women without rUTIs, comparing the urinary symptoms and urodynamic data of both groups.

RESULTS

The main significant differences between these groups were age (the women were older in the control group) and the value of abdominal pressure during voiding cystometry (this was higher in the group with rUTIs). After controlling age as a confounding factor, it was confirmed that the value of maximum abdominal pressure during voiding was the only factor to facilitate the rUTIs and the ideal cut-off was 28 cm H(2)O.

CONCLUSIONS

Abdominal strength in the voiding phase constitutes a risk factor for recurrent urinary tract infections in women.

UTIs in patients with neurogenic bladder

Urinary tract infections (UTI) remain one of the most prevalent and frustrating morbidities for neurogenic bladder patients, and death attributed to urosepsis in the spinal cord injury (SCI) patient is higher when compared to the general population. Risk factors include urinary stasis, high bladder pressures, bladder stones, and catheter use. While classic symptoms of UTI include dysuria, increased frequency and urgency, neurogenic bladder patients present differently with increased spasticity, autonomic dysreflexia, urinary incontinence, and vague pains. Multiple modalities have been assessed for prevention including catheter type, oral supplements, bladder irrigation, detrusor injections and prophylactic antimicrobials. Of these, bladder inoculation with E. coli HU2117, irrigation with iAluRil(®), detrusor injections, and weekly prophylaxis with alternating antibiotics appear to have a positive reduction in UTI but require further study. Ultimately, treatment for symptomatic UTI should account for the varied flora and possible antibiotic resistances including relying on urine cultures to guide antibiotic therapy.

Urinary tract infections in children with myelodysplasia in whom clean intermittent catheterization was administered

AIM

In this study, it was aimed to evaluate the frequency of significant bacteriuria and antibiotic resistance characteristics in children with myelodysplasia in whom clean intermittent catheterization was administered.

MATERIAL AND METHODS

The study group was composed of 71 patients with myelodysplasia who were found to have significant bacteriuria (age: 8.20±4.57 years; 39 girls) and the control groups was composed of 49 children who were diagnosed with community-acquired urinary tract infection (age: 7.94±4.17 years; 29 girls). The patient and control groups were evaluated in terms of the microorganisms grown in urinary cultures and antibiotic resistance characteristics. The study approved by the ethics committe (14/02/2012-19/E).

RESULTS

Growth of Escherichia coli (E. coli) was found with the highest rate in myelodysplasic patients. However, when compared with the control group in terms of microorganism types, an increase in the growth rates of the microorganisms excluding E. coli was observed in the patients with myelodysplasia which was close to the significance limit (p=0.055). When antibiotic resistance properties were examined, a significantly increased resistance against cotrimaxazole was found in the patient group compared to the control group (p=0.001). 84.5% of the patients were using prophylactic antibiotic including mainly co-trimoxazole. A significantly increased co-trimoxazole resistance was also found in the patients who were using prophylactic antibiotic compared to the patients who were not using prophylactic antibiotic (p=0.025). The rate of symptomatic UTI was found to be 21% in the patients with myelodysplasia and a significant increase was found in the complaints of abdominal/side pain and nausea/vomiting as well as fever in these patients compared to the patients with asymptomatic bacteriuria (p=0.029 and p=0.032, respectively).

CONCLUSION

Our results show that UTI is still a significant problem in patients with myelodysplasia. In addition, they show that use of prophylactic antibiotic may increase the frequency of development of resistance and co-trimoxazole used for this objective is not a good option..
