SummaryBackground and Aims: PSC is an autoimmune biliary inflammatory disorder that is often associated with inflammatory bowel disease (IBD), with 50%-75% of patients with PSC having coexisting IBD, most commonly ulcerative colitis. Currently, no medical therapies have been shown to improve the disease course or slow its progression. However, ongoing research has resulted in a growing interest in the use of antibiotics for treatment of PSC, of which vancomycin is the most studied. In this review, we summarise the current evidence on the use of vancomycin in PSC and comment on future research areas of interest.Methods: A comprehensive PUBMED and EMBASE literature search for articles on vancomycin, PSC, therapeutic options and microbiome was performed.Results: Two randomised clinical trials, three case series and two case reports were included in the study. These include uncontrolled data from at least 98 patients that include promising improvements in biochemistry and imaging. Optimal dosing regimens are unclear. Conclusion:Vancomycin is one of the most studied antibiotics used in the treatment of PSC with promising results. There is not currently sufficient evidence to support treatment recommendations. Further research is needed to establish if vancomycin is a PSC treatment.
Background Pediatric inflammatory bowel disease (IBD) — consisting of Crohn’s disease (CD) and ulcerative colitis (UC) — can result in significant morbidity requiring frequent healthcare utilization. While it is known that the overall financial impact of pediatric IBD is significant, the direct out-of-pocket (OOP) cost burden on the parents of children with IBD has not been explored. We hypothesized that affected children with a more relapsing disease course and families in lower income strata, ineligible for need-based assistance programs, disparately absorb ongoing financial stress. Methods We completed a cross-sectional analysis among parents of children with IBD residing in California using an online HIPAA-secure Qualtrics survey. Multicenter recruitment occurred between December 4, 2013 and September 18, 2014 at the point-of-care from site investigators, informational flyers distributed at regional CCFA conferences, and social media campaigns equally-targeting Northern, Central, and Southern California. IBD-, patient-, and family-specific information were collected from the parents of pediatric IBD patients <18 years of age at time of study, carry a confirmed diagnosis of CD or UC, reside in and receive pediatric gastroenterology care in California, and do not have other chronic diseases requiring on-going medical care. Results We collected 150 unique surveys from parents of children with IBD (67 CD; 83 UC). The median patient age was 14 years for both CD and UC, with an overall 3.7 years (SD 2.8 years) difference between survey completion and time of IBD diagnosis. Annually, 63.6%, 28.6%, and 5.3% of families had an OOP cost burden >$500, >$1000, and >5000, respectively. Approximately one-third (36.0%) of patients had emergency department (ED) visits over the past year, with 59.2% of these patients spending >$500 on ED copays, including 11.1% who spent >$5,000. While 43.3% contributed <$500 on procedure and test costs, 20.0% spent >$2,000 in the past year. Families with household income between $50k–100k had a statistically significant probability (80.6%) of higher annual OOP costs than families with lower income <$50k (20.0%; P<0.0001) or higher income >$100k (64.6%; P<0.05). Multivariate analysis revealed that clinical variables associated with uncontrolled IBD states correlated to higher OOP cost burden. Annual OOP costs were more likely to be >$500 among patients who had increased spending on procedures and tests (OR 5.63, 95% CI 2.73 – 11.63), prednisone course required over the past year (OR 3.19, 95% CI 1.02 – 9.92), at least one ED visit for IBD symptoms (OR 2.84, 95% CI 1.33 – 6.06), at least 4 or more outpatient primary medical doctor (PMD) visits for IBD symptoms (OR 2.82, 95% CI 1.40 – 5.68), and history of 4 or more lifetime hospitalizations for acute IBD care (OR 2.60, 95% CI 1.13 – 5.96). Conclusions Previously undocumented, a high proportion of pediatric IBD families incur substantial OOP cost burden. Patients who are frequently in relapsing and uncontrolled IBD states require more a...
Unnecessary use of antibiotics is an increasing problem. In this study, we sought to determine the diagnostic accuracy of procalcitonin in predicting bacteremia in children with a central line and fever, and we sought to determine optimal cutoff values to maximize sensitivity and specificity. This is the largest study to date in which procalcitonin is examined as a predictive marker of bacteremia in pediatric patients with a central line and fever. METHODS: We conducted a retrospective cohort study of children aged 0 to 23 years with a central line and fever of 38°C who had procalcitonin and blood cultures drawn before initiation of antibiotics and had no other identified bacterial infection. Patients were also prospectively monitored via a custom-built electronic medical record dashboard for eligibility. RESULTS: There were 523 patients and .2500 procalcitonin values reviewed for eligibility. Of these, 169 (47%) patients and 335 blood cultures with procalcitonin were included. There were 94 (28%) positive bacterial blood cultures and 241 (72%) negative bacterial blood cultures. In bacteremic cultures, the mean procalcitonin level was 9.96 6 15.96 ng/mL, and the median procalcitonin level was 4.85 ng/mL (interquartile range 18.5). In nonbacteremic cultures, the mean procalcitonin level was 1.23 6 10.37 ng/mL, and the median procalcitonin level was 0.3 ng/mL (interquartile range 0.7). A receiver operating characteristic analysis indicated a procalcitonin level of $0.6 ng/mL as the best cutoff point that produced a sensitivity of 85.6% and a specificity of 65.7% (area under the curve 0.85). CONCLUSIONS: Procalcitonin is a sensitive biomarker in predicting bacteremia in children with a central line and fever.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
