Usefulness of mid-regional proadrenomedullin levels in the resuscitation phase of severely burned patients and its utility in early sepsis detection.

INTRODUCTION: Mid-regional proadrenomedullin (MR-proADM) reflects the adrenomedullin level, which has vasodilatory activity, decreases endothelial permeability, and downregulates proinflammatory cytokines. Sepsis diagnosis in these patients is difficult, and MR-proADM is a widely studied sepsis biomarker. This study evaluates MR-proADM levels during the resuscitation phase, considering the potential influence of haemodynamic changes and its usefulness for the early sepsis detection in burn patients. METHODS: A prospective observational study performed in the Critical Burn Unit. Demographic data, burn characteristics, comorbidities, prognostic/severity scales, and haemodynamic parameters were collected. The resuscitation protocol guided by diuresis, transpulmonary thermodilution, and lactate levels was followed. Blood samples were collected at various time points for biomarker measurement. Biomarker levels, including MR-proADM, C-reactive protein, and procalcitonin were measured during the resuscitation phase and septic episodes. RESULTS: Twenty-seven patients were included, with a mean age of 51 years, a mean total body surface area burn of 41.8%, a mean Abbreviated Burn Severity Index of 9.7, and a mean Baux score of 92. MR-proADM levels were elevated on admission (0.9 ± 0.5 nmol/l) and continued to increase slightly during the resuscitation phase (2.4 ± 2.2 nmol/l). Haemodynamic changes during resuscitation did not significantly affect MR-proADM levels. Twelve of the 27 patients developed sepsis, whose MR-proADM levels were significantly elevated on the day of clinical diagnosis (3.91 ± 2.99 nmol/l) and even the day before (2.57 ± 3.37). Higher MR-proADM levels were associated with greater severity as measured by the Sequential Organ Failure Assessment score. The mean MR-proadrenomedullin values during resuscitation in the patients who died was 3.51 ± 2.30 nmol/l, whereas in the survivors it was 1.28 ± 1.10 nmol/l (p = 0.0001). CONCLUSION: MR-proadrenomedullin values are elevated after thermal injury but are not affected by haemodynamic changes. During septic episodes in burn patients, MR-proADM rises early (the day before sepsis diagnosis). Higher levels of MR-proADM are associated with greater organ dysfunction and mortality.

Development of a Prediction Model for Short-Term Remission of Patients with Crohn's Disease Treated with Anti-TNF Drugs.

Therapy with anti-tumor necrosis factor (TNF) has dramatically changed the natural history of Crohn's disease (CD). However, these drugs are not without adverse events, and up to 40% of patients could lose efficacy in the long term. We aimed to identify reliable markers of response to anti-TNF drugs in patients with CD. A consecutive cohort of 113 anti-TNF naive patients with CD was stratified according to clinical response as short-term remission (STR) or non-STR (NSTR) at 12 weeks of treatment. We compared the protein expression profiles of plasma samples in a subset of patients from both groups prior to anti-TNF therapy by SWATH proteomics. We identified 18 differentially expressed proteins (p ≤ 0.01, fold change ≥ 2.4) involved in the organization of the cytoskeleton and cell junction, hemostasis/platelet function, carbohydrate metabolism, and immune response as candidate biomarkers of STR. Among them, vinculin was one of the most deregulated proteins (p < 0.001), whose differential expression was confirmed by ELISA (p = 0.054). In the multivariate analysis, plasma vinculin levels along with basal CD Activity Index, corticosteroids induction, and bowel resection were factors predicting NSTR.

Real-world outcomes of switching from adalimumab originator to adalimumab biosimilar in patients with inflammatory bowel disease: The ADA-SWITCH study.

BACKGROUND AND AIMS: Data on the outcomes after switching from adalimumab (ADA) originator to ADA biosimilar are limited. The aim was to compare the treatment persistence, clinical efficacy, and safety outcomes in inflammatory bowel disease patients who maintained ADA originator vs. those who switched to ADA biosimilar. METHODS: Patients receiving ADA originator who were in clinical remission at standard dose of ADA originator were included. Patients who maintained ADA originator formed the non-switch cohort (NSC), and those who switched to different ADA biosimilars constituted the switch cohort (SC). Clinical remission was defined as a Harvey-Bradshaw index ≤4 in Crohn's disease and a partial Mayo score ≤2 in ulcerative colitis. To control possible confounding effects on treatment discontinuation, an inverse probability treatment weighted proportional hazard Cox regression was performed. RESULTS: Five hundred and twenty-four patients were included: 211 in the SC and 313 in the NSC. The median follow-up was 13 months in the SC and 24 months in the NSC (p < 0.001). The incidence rate of ADA discontinuation was 8% and 7% per patient-year in the SC and in the NSC, respectively (p > 0.05). In the multivariate analysis, switching from ADA originator to ADA biosimilar was not associated with therapy discontinuation. The incidence rate of relapse was 8% per patient-year in the SC and 6% per patient-year in the NSC (p > 0.05). Six percent of the patients had adverse events in the SC vs. 5% in the NSC (p > 0.05). CONCLUSION: Switching to ADA biosimilar did not impair patients' outcomes in comparison with maintaining on the originator.

One year follow-up on a randomized study investigating serratus anterior muscle and pectoral nerves type I block to reduced neuropathic pain descriptors after mastectomy.

Breast cancer is the second most common diagnosed type of cancer in women. Chronic neuropathic pain after mastectomy occurs frequently and is a serious health problem. In our previous single-center, prospective, randomized controlled clinical study, we demonstrated that the combination of serratus anterior plane block (SAM) and pectoral nerve block type I (PECS I) with general anesthesia reduced acute postoperative pain. The present report describes a prospective follow-up study of this published study to investigate the development of chronic neuropathic pain 12 months after mastectomy by comparing the use of general anesthesia alone and general anesthesia with SAM + PECS I. Additionally, the use of analgesic medication, quality of life, depressive symptoms, and possible correlations between plasma levels of interleukin (IL)-1 beta, IL-6, and IL-10 collected before and 24 h after surgery as predictors of pain and depression were evaluated. The results showed that the use of SAM + PECS I with general anesthesia reduced numbness, hypoesthesia to touch, the incidence of patients with chronic pain in other body regions and depressive symptoms, however, did not significantly reduce the incidence of chronic neuropathic pain after mastectomy. Additionally, there was no difference in the consumption of analgesic medication and quality of life. Furthermore, no correlation was observed between IL-1 beta, IL-6, and IL-10 levels and pain and depression. The combination of general anesthesia with SAM + PECS I reduced the occurrence of specific neuropathic pain descriptors and depressive symptoms. These results could promote the use of SAM + PECS I blocks for the prevention of specific neuropathic pain symptoms after mastectomy.Registration of clinical trial: The Research Ethics Board of the Hospital Sirio-Libanes/Brazil approved the study (CAAE 48721715.0.0000.5461). This study is registered at Registro Brasileiro de Ensaios Clinicos (ReBEC), and ClinicalTrials.gov, Identifier: NCT02647385.

Preoperative Management of Medications for Rheumatologic and HIV Diseases: Society for Perioperative Assessment and Quality Improvement (SPAQI) Consensus Statement.

Perioperative medical management is challenging because of the rising complexity of patients presenting for surgical procedures. A key part of preoperative optimization is appropriate management of long-term medications, yet guidelines and consensus statements for perioperative medication management are lacking. Available resources use recommendations derived from individual studies and do not include a multidisciplinary focus on formal consensus. The Society for Perioperative Assessment and Quality Improvement identified a lack of authoritative clinical guidance as an opportunity to use its multidisciplinary membership to improve evidence-based perioperative care. The Society for Perioperative Assessment and Quality Improvement seeks to provide guidance on perioperative medication management that synthesizes available literature with expert consensus. The aim of this consensus statement is to provide practical guidance on the preoperative management of immunosuppressive, biologic, antiretroviral, and anti-inflammatory medications. A panel of experts including hospitalists, anesthesiologists, internal medicine physicians, infectious disease specialists, and rheumatologists was appointed to identify the common medications in each of these categories. The authors then used a modified Delphi process to critically review the literature and to generate consensus recommendations.

Using Interpretable Machine Learning to Identify Baseline Predictive Factors of Remission and Drug Durability in Crohn's Disease Patients on Ustekinumab.

Ustekinumab has shown efficacy in Crohn's Disease (CD) patients. To identify patient profiles of those who benefit the most from this treatment would help to position this drug in the therapeutic paradigm of CD and generate hypotheses for future trials. The objective of this analysis was to determine whether baseline patient characteristics are predictive of remission and the drug durability of ustekinumab, and whether its positioning with respect to prior use of biologics has a significant effect after correcting for disease severity and phenotype at baseline using interpretable machine learning. Patients' data from SUSTAIN, a retrospective multicenter single-arm cohort study, were used. Disease phenotype, baseline laboratory data, and prior treatment characteristics were documented. Clinical remission was defined as the Harvey Bradshaw Index ≤ 4 and was tracked longitudinally. Drug durability was defined as the time until a patient discontinued treatment. A total of 439 participants from 60 centers were included and a total of 20 baseline covariates considered. Less exposure to previous biologics had a positive effect on remission, even after controlling for baseline disease severity using a non-linear, additive, multivariable model. Additionally, age, body mass index, and fecal calprotectin at baseline were found to be statistically significant as independent negative risk factors for both remission and drug survival, with further risk factors identified for remission.

Myostatin Levels and the Risk of Myopenia and Rheumatoid Cachexia in Women with Rheumatoid Arthritis.

Background: Myostatin is a regulator of muscle size. To date, there have been no published studies focusing on the relation between myostin levels and myopenia in rheumatoid arthritis (RA). Objective: Evaluate the value of serum myostatin as a biomarker of cachexia and low skeletal muscle mass (LSMM) in RA patients, along with whether high serum myostatin is associated to these conditions after adjusting for potential confounders. Methods: This cross-sectional study included 161 female RA patients and 72 female controls. In the RA group, we assessed several potential risk factors for LSMM and rheumatoid cachexia. Dual-energy X-ray absorptiometry was used to quantify the skeletal muscle mass index (SMMI) (considering LSMM ≤ 5.5 kg/m2) and the presence of rheumatoid cachexia (a fat-free mass index ≤ 10 percentile and fat mass index ≥ 25 percentile of the reference population). Serum myostatin concentrations were determined by ELISA. To identify a cut-off for high serum myostatin levels, we performed ROC curve analysis. Multivariable logistic regression analysis was used to identify the risk factors for LSMM and rheumatoid cachexia. The risk was expressed as odds ratios (ORs) and their 95% confidence intervals (95% CIs). Results: Compared to the controls, the RA group had a higher proportion of LSMM and exhibited high serum myostatin levels (p < 0.001). ROC curve analysis showed that a myostatin level ≥ 17 ng/mL was the most efficient cut-off for identifying rheumatoid cachexia (sensitivity: 53%, specificity: 71%) and LSMM (sensitivity: 43%, specificity: 77%). In the multivariable logistic regression, RA with high myostatin levels (≥17 ng/mL) was found to increase the risk of cachexia (OR = 2.79, 95% CI: 1.24-6.29; p = 0.01) and LSMM (OR = 3.04, 95% CI: 1.17-7.89; p = 0.02). Conclusions: High serum myostatin levels increase the risk of LSMM and rheumatoid cachexia. We propose that high myostatin levels are useful biomarkers for the identification of patients in risk of rheumatoid cachexia and myopenia.

Long-Term Real-World Effectiveness and Safety of Ustekinumab in Crohn's Disease Patients: The SUSTAIN Study.

BACKGROUND: Large real-world-evidence studies are required to confirm the durability of response, effectiveness, and safety of ustekinumab in Crohn's disease (CD) patients in real-world clinical practice. METHODS: A retrospective, multicentre study was conducted in Spain in patients with active CD who had received ≥1 intravenous dose of ustekinumab for ≥6 months. Primary outcome was ustekinumab retention rate; secondary outcomes were to identify predictive factors for drug retention, short-term remission (week 16), loss of response and predictive factors for short-term efficacy and loss of response, and ustekinumab safety. RESULTS: A total of 463 patients were included. Mean baseline Harvey-Bradshaw Index was 8.4. A total of 447 (96.5%) patients had received prior biologic therapy, 141 (30.5%) of whom had received ≥3 agents. In addition, 35.2% received concomitant immunosuppressants, and 47.1% had ≥1 abdominal surgery. At week 16, 56% had remission, 70% had response, and 26.1% required dose escalation or intensification; of these, 24.8% did not subsequently reduce dose. After a median follow-up of 15 months, 356 (77%) patients continued treatment. The incidence rate of ustekinumab discontinuation was 18% per patient-year of follow-up. Previous intestinal surgery and concomitant steroid treatment were associated with higher risk of ustekinumab discontinuation, while a maintenance schedule every 12 weeks had a lower risk; neither concomitant immunosuppressants nor the number of previous biologics were associated with ustekinumab discontinuation risk. Fifty adverse events were reported in 39 (8.4%) patients; 4 of them were severe (2 infections, 1 malignancy, and 1 fever). CONCLUSIONS: Ustekinumab is effective and safe as short- and long-term treatment in a refractory cohort of CD patients in real-world clinical practice.

This large retrospective study demonstrated the short- and long-term effectiveness and safety of ustekinumab in patients with Crohn's disease in real-world clinical practice, including those with refractory disease.

Mesalazine induced interstitial pneumonitis in the COVID era.

Mesalazine is the most widely used aminosalicylate for induction and maintenance of remission in patients with mild-to-moderate ulcerative colitis (UC). Drug-induced hypersensitivity pneumonitis is considered very rare (<1/10.000 patients). Due to its rarity and the scarce cases reported, mesalazine-induced lung injury needs to be highly suspected in a patient with onset of respiratory symptoms and UC under treatment with salicylates. It should make the clinician formulate a differential diagnosis that includes not only infections (tuberculosis, bacterial...) or the inflammatory bowel disease itself, but also the current coronavirus disease 2019 (COVID-19) since their clinical and radiological manifestations may be very similar.

Risk of Immunomediated Adverse Events and Loss of Response to Infliximab in Elderly Patients with Inflammatory Bowel Disease: A Cohort Study of the ENEIDA Registry.

BACKGROUND AND AIMS: Immunomediated adverse events [IAEs] are the most frequently reported infliximab [IFX]-related adverse events. Combination therapy may reduce their incidence, although this strategy is not recommended in elderly patients. We aimed to compare the rates of IFX-related IAEs and loss of response [LOR] in elderly and younger patients. METHODS: Adult patients in the ENEIDA registry who had received a first course of IFX therapy were identified and grouped into two cohorts regarding age at the beginning of treatment [over 60 years and between 18 and 50 years]. The rates of IAEs and LOR were compared. RESULTS: In total, 939 patients [12%] who started IFX over 60 years of age and 6844 [88%] below 50 years of age were included. Elderly patients presented a higher proportion of AEs related to IFX [23.2% vs 19%; p = 0.002], infections [7.1% vs 4.3%; p < 0.001] and neoplasms [2.2% vs 0.5%; p < 0.001]. In contrast, the rates of IAEs [14.8% vs 14.8%; p = 0.999], infusion reactions [8.1% vs 8.1%; p = 0.989], late hypersensitivity [1.3% vs 1.2%; p = 0.895], paradoxical psoriasis [1% vs 1.5%; p = 0.187] and drug-induced lupus erythematosus [0.6% vs 0.7%; p = 0.947] were similar in elderly and younger patients. LOR rates were also similar between the two groups [20.5% vs 19.3%; p = 0.438]. In the logistic regression analysis, IFX monotherapy, extraintestinal manifestations and female gender were the only risk factors for IAEs, whereas IFX monotherapy, extraintestinal manifestations and Crohn's disease were risk factors for LOR. CONCLUSIONS: Elderly patients with inflammatory bowel disease have a similar risk of developing IFX-related IAEs and LOR to that of younger patients.

High Dose Ascorbic Acid During Acute Resuscitation in Critically Burn Patients.

Ascorbic acid (AA) is a potent oxygen-free radical scavenger. We hypothesized that treating severe burn patients with high doses of AA (HDAA) can reduce fluid resuscitation requirements and prevent organ dysfunction. We performed a unicentric, retrospective case-control study of 75 burn patients: 25 patients admitted from 2018 to 2019 with more than 30% Total Surface Body Surface Area (TSBA) burned who received HDAA (66 mg/kg/h as soon as possible after admission until 36 h after injury), and 50 patients admitted from 2014 to 2017 with similar Abbreviated Burn Severity Index (ABSI)/Baux scores who were treated with the same protocol but did not receive HDAA. During the first 24 hours of burn resuscitation the HDAA group required less fluids than the control group (3.06 ± 0.87 ml/kg/%TBSA vs 4.32 ± 1.51 P < .05), but the overall reduction of fluid requirements during the first 72 hours was not significant. There were no significant differences in Sequential Organ Failure Assessment (SOFA), other hemodynamic parameters, complications, or mortality. We also did not find an increase acute kidney injury in patients who received HDAA even though the mean urine oxalate/creatinine ratio was 0.61 (0.02-0.96). We conclude that in severe burn patients treated with a restrictive fluid therapy protocol, administration of HDAA can decrease only the initial fluid requirements but not total fluid intakes. We did not find differences in severity score after resuscitation or in mortality. Nor did we find an increase in renal failure in patients administered with HDAA.

Fendrix vs Engerix-B for Primo-Vaccination Against Hepatitis B Infection in Patients With Inflammatory Bowel Disease: A Randomized Clinical Trial.

INTRODUCTION: To compare Engerix-B and Fendrix hepatitis B virus for primo vaccination in inflammatory bowel disease (IBD). METHODS: Patients with IBD were randomized 1:1 to receive Engerix-B double dose or Fendrix single dose at months 0, 1, 2, and 6. Anti-HBs titers were measured 2 months after the third and fourth doses. Response to vaccination was defined as anti-HBs ≥100 UI/L. Anti-HBs titers were measured 2 months after the third and fourth doses and again at 6 and 12 months after the fourth dose. RESULTS: A total of 173 patients were randomized (54% received Engerix-B and 46% Fendrix). Overall, 45% of patients responded (anti-HBs ≥100 IU/L) after 3 doses and 71% after the fourth dose. The response rate after the fourth dose was 75% with Fendrix vs 68% with Engerix-B (P = 0.3). Older age and treatment with steroids, immunomodulators, or anti-tumor necrosis factor were associated with a lower probability of response. However, the type of vaccine was not associated with the response. Anti-HBs titer negativization occurred in 13% of patients after 6 months and 20% after 12 months. Anti-HBs ≥100 IU/L after vaccination was the only factor associated with maintaining anti-HBs titers during follow-up. DISCUSSION: We could not demonstrate a higher response rate of Fendrix (single dose) over Engerix-B (double dose). A 4-dose schedule is more effective than a 3-dose regimen. Older age and treatment with immunomodulators or anti-tumor necrosis factors impaired the success. A high proportion of IBD patients with protective anti-HBs titers after vaccination loose them over time. The risk of losing protective anti-HBs titers is increased in patients achieving anti-HBs <100 IU/L after the vaccination.

Antitumor Necrosis Factor Agents to Treat Endoscopic Postoperative Recurrence of Crohn's Disease: A Nationwide Study With Propensity-Matched Score Analysis.

INTRODUCTION: Patients with Crohn's disease experiencing endoscopic postoperative recurrence (POR) may benefit from antitumor necrosis factor (TNF) agents but scarce data on this are available. Our aim was to assess the efficacy of anti-TNF in improving mucosal lesions in patients with endoscopic POR. METHODS: Multicenter, retrospective, study of patients with Crohn's disease who underwent therapy with anti-TNF agents for endoscopic POR (Rutgeerts score > i1). Treatment outcomes were assessed by the findings in the last ileocolonoscopy performed after anti-TNF therapy was initiated. Endoscopic improvement and remission were defined as any reduction in the baseline Rutgeerts score and by a Rutgeerts score < i2, respectively. RESULTS: A total of 179 patients were included, 83 were treated with infliximab and 96 with adalimumab. Median time on anti-TNF therapy at the last endoscopic assessment was 31 months (interquartile range, 13-54). Endoscopic improvement was observed in 61%, including 42% who achieved endoscopic remission. Concomitant use of thiopurines and treatment with infliximab were associated with endoscopic improvement (odds ratio [OR] 2.15, 95% confidence interval [CI] 1.04-4.46; P = 0.03, and OR 2.34, 95% CI 1.18-4.62; P < 0.01, respectively) and endoscopic remission (OR 3.16, 95% CI 1.65-6.05; P < 0.01, and OR 2.01, 95% CI 1.05-3.88; P = 0.04, respectively) in the multivariable logistic regression analysis. These results were confirmed in a propensity-matched score analysis. DISCUSSION: In patients with endoscopic POR, anti-TNF agents improve mucosal lesions in almost two-thirds of the patients. In this setting, concomitant use of thiopurines and use of infliximab seem to be more effective in improving mucosal lesions.

Diabetes tipo 2 em doentes com mais de 35 anos na população de Villafranco Del Guadiana / Type 2 diabetes in patients aged over 35 years in the population of Villafranco Del Guadiana

A diabetes é uma das maiores epidemias do século XXI a nível mundial, especialmente a diabetes mellitus tipo 2, sendo esta situação agravada com as previsões futuras negativistas, tendo um impacto significativo tanto a nível da saúde como a nível económico, e, estando por outro lado intimamente relacionada com fatores de risco cardiovascular, como a presença de obesidade ou inatividade física, ambos fatores crescentes na população atual. Motivada pela necessidade de conhecer a distribuição desta doença na população onde presto cuidados, foi realizado um estudo "Prevalência de Diabetes tipo 2 em indivíduos com mais de 35 anos na localidade de Villafranco del Guadiana", em uma amostra de 106 indivíduos, 65 homens e 41 mulheres, obtendo-se um resultado de 11,67%, que se assemelha ao resto da Espanha e ao mundo. Como aluna do Mestrado em Enfermagem Comunitária e Saúde Pública e de acordo com as Estratégias de Abordagem à Doença Crónica do SNS e da OMS efetuámos um projeto de intervenção comunitária, utilizando a metodologia de Planeamento em Saúde, e direcionado para o diagnóstico precoce da doença, bem como para a modificação de estilos de vida de doentes já diagnosticados e da população em geral com o objetivo final de tentar reduzir estes números alarmantes e procurando dar resposta a este problema.

Diabetes is one of the largest epidemics of the 21st century worldwide, especially type 2 diabetes mellitus, and this situation is aggravated by future negativist forecasts, having a significant impact both in the terms of health and at the economic level, and, on the other hand, closely related to cardiovascular risk factors, such as the presence of obesity or physical inactivity, both increasing factors in the current population. Motivated by the need to know the distribution of this disease in the population where I care, a study was conducted "Prevalence of Type 2 Diabetes in individuals over 35 years of age in the locality of Villafranco del Guadiana", in a sample of 106 individuals, 65 men and 41 women, obtaining a result of 11.67%, which is similar to the rest of Spain and the world. As a student of the Master's degree in Community Nursing and Public Health and in accordance with the Strategies for Addressing Chronic Disease of the SNS and WHO we carried out a community intervention project, using the Methodology of Health Planning, and directed to the early diagnosis of the disease, as well as to the modification of lifestyles of patients already diagnosed and the general population with the ultimate goal of trying to reduce these alarming numbers and seeking to respond to this problema.

Real-world long-term effectiveness of ustekinumab in Crohn's disease: results from the ENEIDA registry.

BACKGROUND: Data on the long-term administration of ustekinumab in recommended doses are limited. AIM: To assess the real-world, long-term effectiveness of ustekinumab in refractory Crohn's disease (CD). METHODS: Multi-centre study of CD patients starting ustekinumab at the recommended dose, followed for 1 year. Values for the Harvey-Bradshaw Index (HBI), endoscopic activity, C-reactive protein (CRP), and faecal calprotectin (FC) were recorded at baseline and at weeks 26 and 52. Demographic and clinical data, previous treatments, adverse events (AEs) and hospitalisations were documented. Potential predictors of remission were examined. RESULTS: A total of 407 patients were analysed. The initial maintenance dose of 90 mg SC was administered every 12, 8 and 4 weeks in 56 (14%), 347 (85%) and 4 (1%) patients, respectively. After 52 weeks, treatment was discontinued in 112 patients (27.5%). At baseline, 295 (72%) had an HBI >4 points. Of these, 169 (57%) and 190 (64%) achieved clinical remission at weeks 26 and 52, respectively. FC levels returned to normal in 44% and 54% of patients at weeks 26 and 52, and CRP returned to normal in 36% and 37% of patients at weeks 26 and 52, respectively. AEs were recorded in 60 patients. The use of fewer previous anti-TNFα agents and ileal localisation were associated with clinical remission, and endoscopic severity was associated with poor response. No factors correlated with endoscopic remission. CONCLUSION: After 52 weeks, ustekinumab demonstrated effectiveness in inducing clinical and endoscopic remission in patients with refractory CD.

Changes in the requirement for early surgery in inflammatory bowel disease in the era of biological agents.

BACKGROUND AND AIM: Biological therapies may be changing the natural history of inflammatory bowel diseases (IBDs), reducing the need for surgical intervention. We aimed to assess whether the availability of anti-TNF agents impacts the need for early surgery in Crohn's disease (CD) and ulcerative colitis (UC). METHODS: Retrospective, cohort study of patients diagnosed within a 6-year period before and after the licensing of anti-TNFs (1990-1995 and 2007-2012 for CD; 1995-2000 and 2007-2012 for UC) were identified in the ENEIDA Registry. Surgery-free survival curves were compared between cohorts. RESULTS: A total of 7370 CD patients (2022 in Cohort 1 and 5348 in Cohort 2) and 8069 UC patients (2938 in Cohort 1 and 5131 in Cohort 2) were included. Immunosuppressants were used significantly earlier and more frequently in both CD and UC post-biological cohorts. The cumulative probability of surgery was lower in CD following anti-TNF approval (16% and 11%, 22% and 16%, and 29% and 19%, at 1, 3, and 5 years, respectively P < 0.0001), although not in UC (3% and 2%, 4% and 4%, and 6% and 5% at 1, 3, and 5 years, respectively; P = 0.2). Ileal involvement, older age at diagnosis and active smoking in CD, and extensive disease in UC, were independent risk factors for surgery, whereas high-volume IBD centers (in both CD and UC) and immunosuppressant use (in CD) were protective factors. CONCLUSIONS: Anti-TNF availability was associated with a reduction in early surgery for CD (driven mainly by earlier and more widespread immunosuppressant use) but not in UC.

Adalimumab or Infliximab for the Prevention of Early Postoperative Recurrence of Crohn Disease: Results From the ENEIDA Registry.

BACKGROUND: Anti-tumor necrosis factor agents (anti-TNFs) are efficacious at preventing the postoperative recurrence (POR) of Crohn disease, as demonstrated in 2 randomized controlled trials. However, real-life data for infliximab or adalimumab in this setting are scarce. Our aim was to assess both the efficiency of anti-TNFs at preventing early POR of Crohn disease in clinical practice and the associated risk factors for POR. METHODS: Patients in whom anti-TNFs were prescribed for the prevention of POR within 3 months after ileocolonic resection and who had an endoscopic assessment within 18 months were identified from the ENEIDA registry. Clinical and endoscopic features were collected within 18 months after surgery. RESULTS: In total, 152 patients were included (55 treated with infliximab, 97 with adalimumab, and 39% with concomitant immunosuppressants). Anti-TNF treatment was started after a median time of 29 days (IQR 13-44) after surgery. Eighty-two percent of patients had at least one risk factor for POR, and 82% had been exposed to anti-TNFs before the index surgery. Overall, 34% had endoscopic POR (as defined using a Rutgeerts endoscopic score > i1); 14% had advanced endoscopic POR (>i2); and 20% had clinical POR, with no differences between infliximab and adalimumab. In the multivariate analysis, only perianal disease (odds ratio 2.73, 95% confidence interval [CI] 1.26-5.91) and rectal involvement (odds ratio 2.79, 95% CI 1.09-7.14) were independent predictors of endoscopic POR. CONCLUSIONS: In clinical practice, anti-TNFs for the prevention of POR of Crohn disease are frequently used in patients experienced with anti-TNFs and with concomitant immunosuppressants. The efficacy of infliximab and adalimumab for POR prevention is similar and in accordance with the results obtained in randomized controlled trials.

Characteristics of inflammatory bowel disease in patients of Roma/Gypsy ethnicity. A case-control study.

BACKGROUND: Peculiarities of inflammatory bowel disease (IBD) have been explored in ethnic groups, such as Asians, Hispanics, and Afro-Americans, but not in other ethnic minorities, such as Roma/Gypsies. METHODS: In a retrospective, hospital-based study, all adult Roma/Gypsy patients included in the IBD databases of seven Spanish centres were identified as cases. For each Roma/Gypsy patient, a Caucasian patient, matched for several demographic features, was searched as a control. Data on phenotypic features, therapeutic requirements, and familial aggregation were recorded. RESULTS: Sixty-eight Roma/Gypsy patients were identified, 29 of them being women. The mean age at diagnosis of IBD was 24.9±9.5years, and the mean time elapsed since diagnosis was 96.6±72.2months. Roma/Gypsy IBD patients showed a significantly higher rate of familial aggregation (43%) than their Caucasian controls (9%) (p=0.00001). CD in Roma/Gypsies had more often a complicated pattern (mainly penetrating) while UC patients showed a marked trend to more often developing extraintestinal manifestations. In addition, Roma/Gypsy IBD patients had a somewhat greater need for immunosuppressants, biological agents or surgery. CONCLUSIONS: These are the first data on IBD in Roma/Gypsy patients. Familial aggregation is the most prominent feature in these patients, suggesting a predominant role of genetics in its pathogenesis.
