BackgroundCT-P13 is a biosimilar of Remicade®, an agent approved in some countries for use in inflammatory bowel disease (IBD). Controlled clinical trials have demonstrated the efficacy and safety of CT-P13 in rheumatic diseases, but not in IBD.AimsTo assess the effectiveness and safety of CT-P13 in IBD patients in real clinical practice.MethodsThis is a prospective observational study in patients with moderate to severe Crohn’s disease or ulcerative colitis treated with CT-P13. The study was performed in one single center. Patients included were naive or switched to anti-TNF treatment from the reference infliximab (Remicade®) to CT-P13. Efficacy and safety were assessed in naive and switched patients who were in remission at the time of the switch at months 3 and 6 of therapy.Results87.5 and 83.9% of switched CD patients who were in remission at the time of the switch continued in remission, and 66.7 and 50% of naive CD patients reached remission, at months 3 and 6. In UC switched cases, 92 and 91.3% of patients in remission at the time of the switch continued in remission, at 3 and 6 months. In naive UC patients, the remission rates were 44.4 and 66.7%, at months 3 and 6. Adverse events occurred in 7.5% of patients during 6 months of study.ConclusionsCT-P13 was efficacious and well tolerated in patients with CD or UC.

S100B protein showed higher prognostic capacity than NSE to predict short/long-term mortality in sTBI patients.

Within the first 6 hours post-TBI, serum S100β seems to be an effective biochemical indicator of IL in patients without a decrease in consciousness. These results indicate that higher S100β cut-off values substantially improve the clinical relevance of this protein.

Despite improvements in the process of organ donation and transplants, the number of organ donors is progressively declining in developed countries. Therefore, the early detection of patients at risk for brain death (BD) is a priority for transplant teams seeking more efficient identification of potential donors. In the extensive literature on S100B as a biomarker for traumatic brain injury (TBI), no evidence appears to exist on its prognostic capacity as a predictor of BD after severe TBI. The objective of this study is to assess the value of including acute S100B levels in standard clinical data as an early screening tool for BD after severe TBI. This prospective study included patients with severe TBI (Glasgow Coma Scale score [GCS] £ 8) admitted to our Neurocritical Care Unit over a 30 month period. We collected the following clinical variables: age, gender, GCS score, pupillary alterations at admission, hypotension and pre-hospital desaturation, CT scan results, isolated TBI or other related injuries, Injury Severity Score (ISS), serum S100B levels at admission and 24 h post-admission, and a final diagnosis regarding BD. Of the 140 patients studied, 11.4% developed BD and showed significantly higher S100B concentrations ( p < 0.001). Multivariate analysis showed that bilateral unresponsive mydriasis at admission and serum S100B at 24 h post-admission had odds ratios (ORs) of 21.35 ( p = 0.005) and 4.9 ( p = 0.010), respectively. The same analysis on patients with photomotor reflex in one pupil at admission left only the 24 h S100B sample in the model (OR = 15.5; p = 0.009). Receiver operating characteristics (ROC) curve analysis on this group showed the highest area under the curve (AUC) (0.86; p = 0.001) for 24 h S100B determinations. The cut off was set at 0.372 lg/L (85.7% sensitivity, 79.3% specificity, positive predictive value [PPV] = 18.7% and negative predictive value [NPV] = 98.9%). This study shows that pupillary responsiveness at admission, as well as 24 h serum S100B levels, could serve as screening tools for the early detection of patients at risk for BD after severe TBI.

The realization of multifactorial interventions involving professionals from both levels of care could be an effective strategy to improve the use of antimicrobials in primary care.

BackgroundBiological agents, such as infliximab, have transformed the outcomes of patients with immune-mediated inflammatory diseases. The advent of biosimilar treatment options such as CT-P13 promises to improve the availability of biological therapy, yet real-world switching data are currently limited. Here, we assess the effectiveness and safety of switching to CT-P13 from infliximab reference product (RP) in patients with inflammatory bowel disease.Materials and methodsThis was a prospective single-center observational study in patients with moderate to severe Crohn’s disease (CD) and ulcerative colitis (UC). All patients were switched from infliximab RP (Remicade) to CT-P13 treatment and followed up for up to 12 months. The efficacy endpoint was the change in clinical response assessed at 3-monthly intervals, according to the Harvey–Bradshaw score and partial Mayo score for patients with CD and UC, respectively. C-reactive protein (CRP) was also measured. Adverse events were monitored and recorded throughout the study.ResultsA total of 98 patients with inflammatory bowel disease (67 CD/31 UC) were included. A total of 83.6% (56/67) of patients with CD were in remission at the time of the switch and 62.7% were in remission at 12 months. The Harvey–Bradshaw score showed a significant change at 12 months (P=0.007) but no significant change was observed in median CRP at this timepoint (P=0.364). A total of 80.6% (25/31) of patients with UC were in remission at the time of the switch and 65.3% (18/28) were in remission at 12 months. No significant changes in the median partial Mayo score (P=0.058) or CRP (P=0.329) were observed at 12 months. Serious adverse events related to medication were reported in 11 (11.2%) patients.ConclusionSwitching from infliximab RP to CT-P13 is efficacious and well tolerated in patients with CD or UC for up to 12 months.
