Diverticular Inflammation and Complication Assessment classification, CODA score and fecal calprotectin in clinical assessment of patients with diverticular disease: A decision curve analysis.

BACKGROUND AND AIMS: The Diverticular Inflammation and Complication Assessment (DICA) classification and the Combined Overview on Diverticular Assessment (CODA) were found to be effective in predicting the outcomes of Diverticular Disease (DD). We ascertain whether fecal calprotectin (FC) can further aid in improving risk stratification. METHODS: A three-year international, multicentre, prospective cohort study was conducted involving 43 Gastroenterology and Endoscopy centres. Survival methods for censored observations were used to estimate the risk of acute diverticulitis (AD) in newly diagnosed DD patients according to basal FC, DICA, and CODA. The net benefit of management strategies based on DICA, CODA and FC in addition to CODA was assessed with decision curve analysis, which incorporates the harms and benefits of using a prognostic model for clinical decisions. RESULTS: At the first diagnosis of diverticulosis/DD, 871 participants underwent FC measurement. FC was associated with the risk of AD at 3 years (HR per each base 10 logarithm increase: 3.29; 95% confidence interval, 2.13-5.10) and showed moderate discrimination (c-statistic: 0.685; 0.614-0.756). DICA and CODA were more accurate predictors of AD than FC. However, FC showed high discrimination capacity to predict AD at 3 months, which was not maintained at longer follow-up times. The decision curve analysis comparing the combination of FC and CODA with CODA alone did not clearly indicate a larger net benefit of one strategy over the other. CONCLUSIONS: FC measurement could be used as a complementary tool to assess the immediate risk of AD. In all other cases, treatment strategies based on the CODA score alone should be recommended.

Prevalence and Natural History of Segmental Colitis Associated With Diverticulosis.

INTRODUCTION: We assessed the prevalence and clinical outcomes of segmental colitis associated with diverticulosis (SCAD) in patients with newly diagnosed diverticulosis. METHODS: A 3-year international, multicenter, prospective cohort study was conducted involving 2,215 patients. RESULTS: SCAD diagnosis was posed in 44 patients (30 male patients; median age: 64.5 years; prevalence of 1.99%, 95% confidence interval, 1.45%-2.66%). Patients with SCAD types D and B showed worse symptoms, higher fecal calprotectin values, needed more steroids, and reached less likely complete remission. DISCUSSION: Although SCAD generally had a benign outcome, types B and D were associated with more severe symptoms and worse clinical course.

Incidental papillary thyroid microcarcinoma in consecutive patients undergoing thyroid surgery for benign disease. A single center experience.

BACKGROUND: There has recently been an increase in the incidental histological diagnosis of papillary thyroid microcarcinoma (I-PTMC), that varies from 3.5% in autopsies studies, to 5.2% in thyroid specimens from thyroid surgery, up to 9.4% in patients from areas of endemic goiter. AIM: To evaluate the incidence and the histological characteristics of I-PTMC in patients undergoing thyroidectomy for benign thyroid diseases, and to evaluate sex, age, toxic and non-toxic goiter, Hashimoto's thyroiditis as potential risk factors. MATERIALS AND METHODS: Prospective observational study on 124 patients, median age 56.3±13.25sd range 24-80 years, 93(75%)F, 31(25%)M, with surgical indications for toxic and non-toxic uni/multinodular goiters, in pharmacological euthyroidism. An accurate histological examination (HE) of entirely embedding thyroid samples was performed to identify microscopic foci of I-PTCM. Logistic regression analysis of the abovementioned parameters was performed to identify the risk factors. RESULTS: Total incidence of I-PTMC was 15.3%(19/124), with F/M ratio 2:1. All I-PTMCs were intraparenchymal with an intact thyroid capsule; 68.5% were bilateral-multifocal, 21% unilateral-unifocal, 10.5% unilateral-multifocal; maximum diameter was <5mm in 57.9% and ≥5mm in 42.1%; 63.1% were follicular variant, 36.9% classical variant; intra-thyroid lymphatic invasion and lymph node infiltration of the central compartment and para-tracheal was found in the only patient with "tall-cell" classical variant. No risk factors was found. CONCLUSIONS: The incidence higher than that reported in the literature, is probably due to the accurate HE of entirely embedding thyroid samples, which is the most important tool to identify microscopic foci of I-PTCM. The highest reported rate of bilateral multifocality of the neoplasm recommend the total thyroidectomy as surgical treatment of choice, also in patients undergoing thyroid surgery for "presumptive" benign diseases.

A rare case of primary gastric Burkitt's lymphoma associated with malignant pleural mesothelioma.

BACKGROUND: Primary gastric Burkitt lymphoma (PG BL) and malignant pleural mesothelioma (MPM) are rare and aggressive tumors with poor prognosis. HIV and EBV infection have a link in the aetiology of PG BL, while MPM is usually associated with asbestos exposure. Endoluminal bleeding from massive solid tumor, and dyspnea usually due to pleural effusion, are the typical clinical manifestations respectively of PG BL and MPM. In most patients just palliative treatment is indicated. CASE REPORT: A caucasian elderly male, negative for the proven risk factors, presenting respiratory failure due to massive left pleural effusion with severe mediastinal shift. Contrast enhanced - Computed Tomography (CE-CT) showed a large mass causing circumferential thickening of the gastric fundus, infiltrating the left diaphragmatic dome and the ipsilateral crus. Macroscopically, on endoscopy the gastric fundus appeared completely occupied by an ulcerated large mass protunding in the gastric lumen. Histopathological examination from biopsy specimens taken during esophagogastroduodenoscopy and thoracoscopy allowed to make diagnosis of PG BL and MPM. The patient first underwent a placement of a chest tube drainage for the pleural effusion and then a thoracoscopic talc insufflation (TTI) in the left hemithorax. A surgical treatment of the gastric lesion was planned, due to the rapid growth and the high risk of bleeding. The patient died because of fatal cardiac arrhythmia, before undergoig abdominal surgery. CONCLUSIONS: This report presents an unique case of PG BL associated with MPM and highlights the real challenge for the physicians to identify them in early stage, especially in patients without the proved risk factors. The onset symptoms make it a very singular case, characterized by severe dyspnea up to respiratory failure, due to massive left pleural effusion and contralateral mediastinal fluttering, without an active bleeding from the gastric mass, while CE-CT findings were instead negative for pleural thickening and positive for circumferential thickening of the gastric fundus.

Faecalibacterium prausnitzii is not decreased in symptomatic uncomplicated diverticular disease of the colon.

In this letter, assessment of the amount of fecal Faecalibacterium prausnitzii in symptomatic uncomplicated diverticular disease (SUDD) is described. Among 44 consecutive patients, comprising 15 SUDD patients, 13 patients with asymptomatic diverticulosis (AD), and 16 healthy controls (HC), the fecal amount of Faecalibacterium prausnitzii was not found to be significantly different between HC, AD and SUDD subjects (p=0.871). Moreover, its count in the HC microbiota (-4.57 ± 2.15) was lower compared with those in the AD (-4.11 ± 1.03) and SUDD subjects (-4.03 ± 1.299). This behavior seems to be different from that occurring in inflammatory bowel disease (IBD) and similar to that of other mucin-degrading species in a SUDD setting.

Comparison of Performances of Adalimumab Biosimilars SB5, ABP501, GP2017, and MSB11022 in Treating Patients with Inflammatory Bowel Diseases: A Real-Life, Multicenter, Observational Study.

BACKGROUND: Adalimumab (ADA) biosimilars have entered the therapeutic armamentarium of inflammatory bowel disease (IBD), allowing for the treatment of a greater number of patients for their reduced cost than the originator. However, comparative data on the efficacy and safety of the various ADA biosimilars remains scarce.We compare the efficacy and safety of ADA biosimilars SB5, ABP501, GP2017, and MSB11022 in treating IBD outpatients in a real-life Italian setting. METHODS: A retrospective analysis was performed on consecutive IBD outpatients with complete clinical, laboratory, and endoscopic data. Clinical activity was measured using the Mayo score in ulcerative colitis (UC) and the Harvey-Bradshaw Index in Crohn's disease (CD). The primary endpoints were the following: (1) induction of remission in patients new to biologics and patients new to ADA but previously exposed to other anti-tumor necrosis factor agents or other biologics; (2) maintenance of remission in patients switched from the ADA originator to an ADA biosimilar; and (3) safety of various biosimilars. RESULTS: A total of 533 patients were enrolled according to the inclusion criteria: 162 patients with UC and 371 patients with CD. Clinical remission was obtained in 79.6% of patients new to biologics and 59.2% of patients new to ADA but not to other biologics; clinical remission was maintained in 81.0% of patients switched from the originator, and adverse events were recorded in 6.7% of patients. There was no significant difference between the 4 ADA biosimilars for each predetermined endpoint. CONCLUSIONS: Adalimumab biosimilars are effective and safe in IBD treatment, both in new patients and in patients switched from the ADA originator. No difference in efficacy and safety was found between ADA biosimilars.

We treated 533 IBD patients with adalimumab (ADA) biosimilars SB5, APB501, GP2017, and MSB11022. No differences between these 4 ADA biosimilars were found for reaching remission in naive patients, maintaining remission for nonmedical switching, clinical response, steroid-free remission, surgery rate, mucosal healing, or safety.

Pilonidal sinus disease. A single center retrospective series analysis.

The surgical approach to chronic pilonidal disease has been significantly changed by minimally invasive and targeted procedures, with the aim to minimize costs and favoring less dressings, faster recovery, and prompt return to work or to school activity. Less invasive procedures are gaining wide acceptance as first approach. We present a single-center experience with the Gips technique, also called Israeli technique or trephine technique, and a brief review of the literature, focusing on minimally invasive procedures. KEY WORDS: Pilonidal Disease, Punch, Minimally Invasive Surgery, Trephines.

Replacement of Adalimumab Originator to Adalimumab Biosimilar for a Non-Medical Reason in Patients with Inflammatory Bowel Disease: A Real-life Comparison of Adalimumab Biosimilars Currently Available in Italy.

BACKGROUND AND AIMS: Adalimumab (ADA) biosimilars have been included into the therapeutic armamentarium of inflammatory bowel disease (IBD); however, comparative data on the efficacy and safety of the different ADA biosimilars after replacing the ADA originator for a non-medical reason remains scarce. We aimed to compare in a real-life setting the efficacy and safety of four ADA biosimilars SB5, APB501, GP2017, and MSB11022 in IBD patients after replacing the originator for a non-medical reason. METHODS: A multicenter retrospective study was performed on consecutive IBD patients, analyzing clinical, laboratory, and endoscopic data. The primary endpoints of the study were maintenance of clinical remission and safety of the different biosimilars. RESULTS: 153 patients were enrolled, 26 with UC and 127 with CD. Clinical remission was maintained in 124 out of 153 (81%) patients after a median (IQR) follow-up of 12 (6-24) months, without any significant difference between the four ADA biosimilars. ADA biosimilars dosage was optimized in five patients (3.3%). Loss of remission was significantly higher in UC patients (10/26 patients, 38.5%) than in CD patients (19/127 patients, 14.9%, p<0.025). Adverse events occurred in 12 (7.9%) patients; the large majority were mild. CONCLUSIONS: No difference in efficacy and safety was found between ADA biosimilars when used to replace the ADA originator for a non-medical reason. However, in UC patients the replacement of ADA originator for this reason should be carefully assessed.

Post-traumatic multifocal abdominal splenosis. The role of the clinical history. Case report and review of literature.

BACKGROUND: Splenosis is a benign clinical condition caused by the heterotopic autotransplantation of spleen's tissue tipically occurring after spleen rupture. Splenosis may be asymptomatic and found accidentally. When signs and symptoms occur they are due to mass effect or bleeding of the splenic nodules. CASE REPORT: 74-years-old male presenting with intestinal sub-occlusion and past medical history of post-traumatic splenectomy at 18-years-old. Based on TC findings of multiple hyperenhanced solid lesions located in greater omentum, mesentery and parietal peritoneum of right pelvic walls, the presumptive diagnosis was peritoneal carcinomatosis of unknown primary site. Stenosis of a ileum loop in the right pelvis, with dilatation and faecal stasis of the upstream loops proximal, required surgical procedure. At the opening of the peritoneal cavity the multifocal lesions varied in size, were reddish blu color, sessile, lobulate and with strong adhesions to the visceral peritoneum. Omentectomy and the blunt exicision of 3 extraparietal solid nodules, which had tenacious adhesions with stenotic ileum loop serosa for the lenght of 8 cm, were performed. Histopathological examination of surgical specimens showed splenic tissue with red pulp. CONCLUSION: CT scan usually do not allow to make a certain diagnosis of splenosis, so the clinical history of splenic trauma or splenectomy, positive in all cases reported in literature, represent the key in the diagnostic pathway of splenosis. Management should be conservative as much as possible nonetheless in abdominal splenosis the surgical approach should be chosen for the symptomatic patients who present abdominal pain, occlusion or bleeding. KEY WORDS: Abdominal, Splenosis, Spleen, Surgery.

Clinical and epidemiological features of ulcerative colitis patients in Sardinia, Italy: Results from a multicenter study.

BACKGROUND: There are little data on the epidemiological and clinical features of adult patients with ulcerative colitis (UC) in the different Italian regions, mainly derived from the absence of a national registry. This prevents correct interpretation of the disease burden. AIM: To assess the main clinical and epidemiological features of adult patients diagnosed with UC in Sardinia, Italy. METHODS: We performed a multicenter, observational, cross-sectional study that included adult patients with UC enrolled in seven gastroenterology unit centers in Sardinia. Data were obtained from the patients' medical records and from a questionnaire administered at the inclusion visit. RESULTS: Four hundred and forty-two patients with UC were included. The median age at diagnosis was 39 years (interquartile range 28-48). After a median disease duration of 10 years, 53 patients experienced proximal extension of proctitis or left-sided colitis. Seventy-five patients developed extraintestinal manifestations. Nineteen patients (4.3%) developed cancer: two with colorectal cancer and seventeen with extracolonic cancers. Mesalazine (5-ASA) remains the mainstay of treatment for UC. Overall, 95 patients (21.5%) were treated with one or more biologic agents, whereas 15 patients (3.4%) underwent surgery, mostly colectomy. CONCLUSION: Our results provide important insights into the clinical and epidemiological features of patients with UC, and while waiting for a national Italian registry, present eligible data on the UC population in Sardinia.

Adalimumab Biosimilar GP2017 versus Adalimumab Originator in Treating Patients with Inflammatory Bowel Diseases: A Real-Life, Multicenter, Observational Study.

The approval of adalimumab (ADA) biosimilars for inflammatory bowel disease (IBD) has reduced the cost of treatment. While several ADA biosimilars are currently available, comparative data on the ADA biosimilar GP2017 (HyrimozTM) and its originator (HumiraTM) in IBD are lacking. We compared the efficacy and safety of GP2017 versus originator in IBD outpatients in an Italian real-life setting. This retrospective analysis enrolled consecutive IBD patients with complete clinical, laboratory, and endoscopic data. Clinical activity was assessed with the Mayo score in ulcerative colitis (UC) and the Harvey-Bradshaw Index in Crohn's disease (CD). The primary endpoints were the induction of remission and the safety of GP2017 versus ADA originator. One hundred and thirty-four patients (30.6% with UC and 69.4% with CD, median age 38 years) were enrolled: 62 (46.3%) patients were treated with GP2017, and 72 (53.7%) with ADA originator; 118 (88.1%) patients were naïve to ADA. Clinical remission was obtained in 105 (78.4%) patients, during a median follow-up of 12 months, 82.3% and 75% in the GP2017 and ADA originator groups, respectively (p = 0.311). Treatment was well tolerated in both groups. This analysis of real-world data suggests that GP2017 and its originator are equivalent in terms of efficacy and safety in patients with IBD.

Comparison of performances of infliximab biosimilars CT-P13 versus SB2 in the treatment of inflammatory bowel diseases: a real-life multicenter, observational study in Italy.

BACKGROUND: To compare the performances of Infliximab (IFX) biosimilar CT-P13 and SB2 in the treatment of Inflammatory Bowel Diseases (IBD) outpatients in Italy. RESEARCH DESIGN AND METHODS: Three hundred and eighty IBD outpatients were retrospectively evaluated. The primary endpoint was to compare the two IFX biosimilars in terms of reaching and maintenance of remission at any timepoint. RESULTS: 197 patients with Ulcerative Colitis (UC) and 183 patients with Crohn's Disease (CD) treated with CT-P13 or SB2 and having a median (IQR) follow-up of 12 (6-36) months were compared: 230 (60.5%) were naïve to anti-TNFα, 20 (5.26%) were switched from IFX originator or from IFX CT-P13 to IFX SB2. Clinical remission was achieved in 133 (67.5%) UC patients and in 164 (89.6%) CD patients (p < 0.000), with no differences between CT-P13 and SB2 in the rate of remission in UC (p = 0.667) and CD (p = 0.286). Clinical response, steroid-free remission, rate of surgery, mucosal healing (MH) in UC, switching from IFX originator or from other biosimilar, and safety were similar. Higher MH rate was obtained in CD patients treated with CT-P13 (p = 0.004). CONCLUSION: This first comparative study found that both IFX biosimilars CT-P13 and SB2 are effective and safe in managing IBD outpatients.

Prognostic performance of the 'DICA' endoscopic classification and the 'CODA' score in predicting clinical outcomes of diverticular disease: an international, multicentre, prospective cohort study.

OBJECTIVE: To investigate the predictive value of the Diverticular Inflammation and Complication Assessment (DICA) classification and to develop and validate a combined endoscopic-clinical score predicting clinical outcomes of diverticulosis, named Combined Overview on Diverticular Assessment (CODA). DESIGN: A multicentre, prospective, international cohort study. SETTING: 43 gastroenterology and endoscopy centres located in Europe and South America. PARTICIPANTS: 2215 patients (2198 completing the study) at the first diagnosis of diverticulosis/diverticular disease were enrolled. Patients were scored according to DICA classifications. INTERVENTIONS: A 3-year follow-up was performed. MAIN OUTCOME MEASURES: To predict the acute diverticulitis and the surgery according to DICA classification. Survival methods for censored observation were used to develop and validate a novel combined endoscopic-clinical score for predicting diverticulitis and surgery (CODA score). RESULTS: The 3-year cumulative probability of diverticulitis and surgery was of 3.3% (95% CI 2.5% to 4.5%) in DICA 1, 11.6% (95% CI 9.2% to 14.5%) in DICA 2 and 22.0% (95% CI 17.2% to 28.0%) in DICA 3 (p<0.001), and 0.15% (95% CI 0.04% to 0.59%) in DICA 1, 3.0% (95% CI 1.9% to 4.7%) in DICA 2 and 11.0% (95% CI 7.5% to 16.0%) in DICA 3 (p<0.001), respectively. The 3-year cumulative probability of diverticulitis and surgery was ≤4%, and ≤0.7% in CODA A; <10% and <2.5% in CODA B; >10% and >2.5% in CODA C, respectively. The CODA score showed optimal discrimination capacity in predicting the risk of surgery in the development (c-statistic: 0.829; 95% CI 0.811 to 0.846) and validation cohort (c-statistic: 0.943; 95% CI 0.905 to 0.981). CONCLUSIONS: DICA classification has a significant role in predicting the risk of diverticulitis and surgery in patients with diverticulosis, which is significantly enhanced by the CODA score. TRIAL REGISTRATION NUMBER: NCT02758860.

Long-term, Real-life, Observational Study in Treating Outpatient Ulcerative Colitis with Golimumab.

BACKGROUND AND AIMS: Several studies have found Golimumab (GOL) effective and safe in the short-term treatment of ulcerative colitis (UC), but few long-term data are currently available from real world. Our aim was to assess the long-term real-life efficacy and safety of GOL in managing UC outpatients in Italy. METHODS: A retrospective multicenter study assessing consecutive UC outpatients treated with GOL for at least 3-month of follow-up was made. Primary endpoints were the induction and maintenance of remission in UC, defined as Mayo score ≤2. Several secondary endpoints, including clinical response, colectomy rate, steroid free remission and mucosal healing, were also assessed during the follow-up. RESULTS: One hundred and seventy-eight patients were enrolled and followed up for a median (IQR) time of 9 (3-18) months (mean time follow-up: 33.1±13 months). Clinical remission was achieved in 57 (32.1%) patients: these patients continued with GOL, but only 6 patients (3.4%) were still under clinical remission with GOL at the 42nd month of follow-up. Clinical response occurred in 64 (36.4%) patients; colectomy was performed in 8 (7.8%) patients, all of them having primary failure. Steroid-free remission occurred in 23 (12.9%) patients, and mucosal healing was achieved in 29/89 (32.6%) patients. Adverse events occurred in 14 (7.9%) patients. CONCLUSIONS: Golimumab does not seem able to maintain long-term remission in UC in real life. The safety profile was good.

Effectiveness and Safety of A Nutraceutical Formulation for the Treatment of Functional Dyspepsia in Primary Care.

BACKGROUND: Although FD may affect up to 10% of the general population, the therapy for FD is not standard. Recently, ginger-based food supplements have been proposed in order to restore FD symptoms. Our aim was to assess the efficacy of a new nutraceutical formulation containing extract of gingerol and thymus as a possible natural treatment in managing the symptoms of functional dyspepsia (FD). METHODS: We retrospectively analyzed the efficacy and safety profiles of a nutraceutical formulation containing Zingiber officinalis root extract and a standardized Thymus extract. It was administered as 1 ml/day twice a day for 90 days. Patients were assessed at baseline and after 1, 2 and 3 months of treatment, following a month of pharmacological washout by completing a questionnaire reporting the trend of the following symptoms: epigastric pain, epigastric heaviness, early satiety, belching, and regurgitation. Every symptom was assessed by a Visual Analogic Scale (VAS), ranging from 0= absence to 10= maximal severity. RESULTS: We enrolled 272 patients (99 males and 173 females; median IQR age 49.5, 36-64 yrs). Obesity (BMI>30) was present in 28 (12.5%) patients; smokers were 83 (30.5%); and comorbidities were present in 107 (39.3%) patients. Improvement of symptom scores during treatment and one month after its suspension was extremely significant (p<0.000). CONCLUSION: This large study found that nutraceutical formulation could be one of the tools for an empirical approach to treat patients with FD, especially when a non-conventional drug treatment is preferable for the patient and considered suitable by the physician.

The prevalence of symptomatic uncomplicated diverticular disease could be lower than expected: a single-center colonoscopy-based cohort study.

AIM: The real prevalence of symptomatic uncomplicated diverticular disease (SUDD) is still unknown. The aim of this study was to assess the prevalence of SUDD, post-diverticulitis SUDD (PD-SUDD) and irritable bowel syndrome (IBS)-like symptoms in a real-life population. METHODS: A cohort of patients, submitted to colonoscopy from 1st January 2012 to 30th April 2018 was revised. RESULTS: A cohort of 5451 patients with diverticulosis was identified during the study period. Abdominal pain was recorded in 1141 patients (20.93%), diarrhea in 288 (5.28%) and constipation in 536 (9.83%) patients. SUDD was recorded in 371 patients (6.81% of the patients having diverticulosis and 32.51% of the patients experiencing abdominal pain), PD-SUDD was recorded in 103 patients (1.89% of the patients having diverticulosis and 9.03% of the patients experiencing abdominal pain) and IBS-like was recorded in 348 patients (6.38% of the patients having diverticulosis and 30.5% of the patients experiencing abdominal pain). Three hundred and nineteen patients were not part of any of the previous categories (5.85% of the patients having diverticulosis and 27.96% of the patients experiencing abdominal pain). SUDD and PD-SUDD were more frequent in older ages (>60 years), while IBS-like symptoms were more frequent in younger. Nonspecific abdominal pain was equally distributed in through the ages. CONCLUSION: The prevalence of SUDD seems to be lower than expected, and most of patients with diverticulosis and abdominal symptoms may suffer from IBS-like or other causes.

Long-term real-life efficacy and safety of infliximab and adalimumab in the treatment of inflammatory bowel diseases outpatients.

BACKGROUND: Infliximab and adalimumab are widely used for the treatment of Crohn's disease and ulcerative colitis. AIM: To compare the long-term efficacy and safety of infliximab and adalimumab in a large cohort of Crohn's disease and ulcerative colitis patients reflecting real-life clinical practice. METHODS: Seven hundred twelve patients were retrospectively reviewed, 410 with Crohn's disease (268 treated with adalimumab and 142 with infliximab; median follow-up 60 months, range, 36-72) and 302 with ulcerative colitis (118 treated with adalimumab and 184 with infliximab; median follow-up 48 months, range, 36-84). RESULTS: In Crohn's disease, clinical remission was maintained in 75.0% of adalimumab vs. in 72.5% of infliximab patients (P = 0.699); mucosal healing and steroid-free remission were maintained in 49.5% of adalimumab vs. 63.9% of infliximab patients (P = 0.077) and in 77.7% of adalimumab vs. 77.3% in infliximab group (P = 0.957), respectively. In ulcerative colitis, clinical remission was maintained in 50.0% of adalimumab vs. 65.8% of infliximab patients (P < 0.000); mucosal healing and steroid-free remission were maintained in 80.6% of adalimumab vs. 77.0% of infliximab patients (P = 0.494) and in 90.2% of adalimumab vs. 87.5% of infliximab patients (P = 0.662), respectively. At the multivariate analysis, ileocolonic location and simple endoscopic score for Crohn's disease >10 were predictors of failure in Crohn's disease; treatment with adalimumab, BMI ≥30 and Mayo score >10 were predictors of failure in ulcerative colitis. infliximab was more likely to cause adverse events than adalimumab (16.6 vs. 6.2%, P < 0.000). CONCLUSION: Both adalimumab and infliximab are effective in long-term outpatients management of inflammatory bowel diseases. Adalimumab had a lower rate of adverse events.

Histological Remission in Ulcerative Colitis in Deep Remission under Treatment with Adalimumab.

BACKGROUND AND AIMS: Histological remission (HR) has been recently demonstrated as the last therapeutic goal in ulcerative colitis (UC), but it is unknown whether and how it may occur. Our aim was to assess the histology during the follow-up of an UC population in deep remission under treatment with adalimumab (ADA). METHODS: We performed a retrospective study on 22 UC patients who were in deep remission and followed-up while receiving therapy with ADA. Colonoscopy in those patients was performed every year. Four-quadrant biopsies every 10 cm were obtained during each colonoscopy and assessed by hematoxylin and eosin stain. Histological activity was classified using the Geboes scale. RESULTS: A total of 22 patients were enrolled in the study. The mean follow-up of those patients was 28±7 months, and 2,592 biopsy specimens in total were taken during 108 colonoscopies performed during the follow-up. At the beginning of the follow-up, histological inflammation was found in 15/22 (68.2%) of patients in deep remissio while receiving maintenance ADA therapy, 8/22 (36.4%) of them with Geboes score ≥3.1. At the end of the follow-up, when patients were still in deep remission while receiving maintenance ADA therapy, only 4 patients (18.2%) had at least one biopsy specimen with evidence of any histological inflammation during the follow-up; only two patients (9.1%) had Geboes score ≥3.1. CONCLUSIONS: Our study shows for the first time that UC patients in deep remission under ADA may reach HR, but it seems slower than other clinical or endoscopic goals.

The natural history of symptomatic uncomplicated diverticular disease: a long-term follow-up study.

BACKGROUND: Symptomatic uncomplicated diverticular disease (SUDD) affects about 20% of patients who have diverticulosis. However, the natural history of SUDD is not yet completely understood. Our aim was to assess the outcomes of a cohort of SUDD patients during a long-term follow up. METHODS: One hundred eighty-five patients suffering from SUDD were identified from a large electronic database. Symptoms assessed were abdominal pain, bloating, bowel movement/day, each of which was scored using a visual analogic scale (VAS); the symptom score was calculated by considering the value of the worst symptom present during assessment. Another VAS was used to assess patients' quality of life (QoL). Patients were treated at the physician's discretion (with rifaximin, mesalazine, probiotics, spasmolytics) only when symptoms occurred during the follow up. Follow-up visit was performed every year or whenever patients consider it necessary. RESULTS: During the follow up (156 months, interquartile range 9-171), 47 patients were lost to follow up. Among these, 9 died from causes not related to SUDD. Acute diverticulitis occurred in 14 patients (7.6% of the overall population): 6 patients (3.2% of the overall population) underwent surgery, and 2 patients (1.1% of the overall population) died because of peritonitis. Both the symptom score and the QoL score were substantially unmodified during the study period. CONCLUSIONS: SUDD is an important disease able to affect patients significantly in the long term. Acute diverticulitis may sometimes occur in these patients, often leading to surgery with possible severe complications.
