Frequency of Bowel Movements and Risk of Diverticulitis. Clin Gastroenterol Hepatol 2022; 20:325-333.e5. [PMID: 33418133 PMCID: PMC8957846 DOI: 10.1016/j.cgh.2021.01.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 12/29/2020] [Accepted: 01/01/2021] [Indexed: 02/07/2023]
Abstract
OBJECTIVE The etiology of diverticulitis is poorly understood. The long-held belief that constipation and low-fiber diet are risk factors for diverticulosis has recently been challenged by studies that suggest that more frequent bowel movements predispose to diverticulosis. We aim to prospectively explore the association between bowel movement frequency and incident diverticulitis. DESIGN We studied participants of the Nurses' Health Study (NHS) and Health Professional Follow-up Study (HPFS). Participants' medical history, lifestyle factors and diet were used in Cox proportional hazards regression models to estimate multivariable-adjusted hazard ratios(HRs) and 95% confidence intervals(CI). RESULTS In the NHS during over 24 years of follow-up encompassing 1,299,922 person-years, we documented 5,214 incident cases of diverticulitis, and in the HPFS over 14 years encompassing 368,661 person-years of follow-up, we documented 390 incident cases of diverticulitis. We observed an inverse association between the frequency of bowel movements and risk of diverticulitis. In the NHS, compared with women who had daily bowel movements, those with more than once daily bowel movements had a HR of 1.30 (95% CI, 1.19, 1.42) and those with less frequent bowel movements had a HR of 0.89 (95% CI, 0.82, 0.95; p-trend < 0.0001). In the HPFS, the corresponding HRs were 1.29 (95% CI, 1.04, 1.59) and 0.61 (95% CI, 0.36, 1.03; p-trend = 0.003). The association between bowel movements and diverticulitis was not modified by categories of age, BMI, physical activity, laxative use or fiber intake. CONCLUSION More frequent bowel movements appear to be a risk factor for subsequent diverticulitis both in men and women. Further studies are needed to understand the potential mechanisms that may underlie this association.

Yan Y, Wu JS, Pan S. Age, alcohol, sex, and metabolic factors as risk factors for colonic diverticulosis. World J Clin Cases 2022; 10:136-142. [PMID: 35071513 PMCID: PMC8727266 DOI: 10.12998/wjcc.v10.i1.136] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 10/28/2021] [Accepted: 11/30/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The pathogenesis of colonic diverticulosis is not well understood. Moreover, only a few studies on colonic diverticulosis have been reported in mainland China.
AIM To evaluate the prevalence of and risk factors for asymptomatic colorectal diverticulosis in Eastern China.
METHODS From August 2016 to July 2020, 6180 asymptomatic individuals were enrolled in this cross-sectional study. These individuals had undergone physical examinations, laboratory testing, and colonoscopy. Data regarding the baseline characteristics and their general health status were obtained through interviews.
RESULTS The prevalence of colonic diverticulosis was 7.3% (449/6180). Colonic diverticulosis was detected predominantly on the right side of the colon (88.4%). Logistic regression analysis revealed that an age ≥ 60 years (adjusted odds ratio [OR] 2.149, 95% confidence interval [CI] 1.511-3.057, P < 0.001), male sex (adjusted OR: 1.878, 95%CI: 1.373-2.568, P < 0.001), obesity (adjusted OR: 1.446, 95%CI: 1.100-1.902, P = 0.008), alcohol intake (adjusted OR: 1.518, 95%CI: 1.213-1.901, P < 0.001), hypertension (adjusted OR: 1.454, 95%CI: 1.181-1.789, P < 0.001), hypertriglyceridemia (adjusted OR: 1.287, 95%CI: 1.032-1.607, P = 0.025), and hyperuricemia (adjusted OR: 1.570, 95%CI: 1.257-1.961, P < 0.001) significantly increased the risk of colonic diverticulosis.
CONCLUSION Advanced age, male sex, alcohol intake, obesity, and other metabolic-related factors, such as hypertension, hypertriglyceridemia, and hyperuricemia, were independent risk factors for colonic diverticulosis. Understanding the true prevalence of colonic diverticulosis and its associated risk factors will aid in its prevention and treatment.

Routine antibiotics may not be needed to treat uncomplicated right diverticulitis: A retrospective cohort study. PLoS One 2021; 16:e0255384. [PMID: 34324608 PMCID: PMC8320899 DOI: 10.1371/journal.pone.0255384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 07/14/2021] [Indexed: 11/19/2022] Open
Abstract
We aimed to investigate whether antibiotic administration is necessary for patients with uncomplicated right colonic diverticulitis. Data from patients diagnosed with uncomplicated right colonic diverticulitis, who received inpatient treatment at a single center between January 2019 and January 2021, were retrospectively examined. The patients were divided into two groups according to whether antibiotics were administered. The patients were matched between groups using propensity score matching in a 1:1 ratio using logistic regression with the nearest-neighbor method. The primary study outcome was the length of hospital stay, and the secondary outcomes were time to the introduction of sips of water and a soft diet. The study included 138 patients who received antibiotics and 59 who did not. After propensity score matching, 55 patients were assigned to each treatment group. There was no significant difference between the two groups in terms of age (p = 0.772), sex (p>0.999), body mass index (p = 0.121), prehospital symptom duration (p = 0.727), initial body temperature (p = 0.661), white blood cell count (p = 0.688), or C-reactive protein level (p = 0.337). There was also no statistically significant difference in the length of hospital stay between the no antibiotic and antibiotic groups (3.1±0.7 days vs. 3.0±1.0 days, p = 0.584). Additionally, no significant difference was observed between the no antibiotic and antibiotic groups with respect to time to sips of water (2.1±0.7 days vs. 1.8±0.9 days, p = 0.100) and time to the introduction of a soft diet (2.4±0.8 days vs. 2.1±0.9 days, p = 0.125). The findings suggest that routine antibiotics may be not required for treating patients with uncomplicated right colonic diverticulitis.

Abstract
Uncomplicated diverticulitis is common, and its evaluation and treatment have evolved over time. Most patients present in a nontoxic manner with localized pain, leukocytosis, and reliable findings on computed tomography (CT). Healthy and stable patients are typically treated in the outpatient setting with very high rates of success. Recently, the necessity of antibiotic therapy has come into question, and several alternative agents have emerged, with the jury still out on their relative roles in diverticular disease. Currently, colonoscopy is still recommended after the resolution of an index episode of uncomplicated diverticulitis, and recurrence rates remain low. Several diet and lifestyle modifications have been shown to impact the rates of diverticulitis recurrence.

Abstract
BACKGROUND Despite the existing evidence, the omission of antibiotics in the management of acute uncomplicated diverticulitis has not gained widespread acceptance. OBJECTIVE This study aims to incorporate the input of both patients and physicians on the omission of antibiotics in uncomplicated diverticulitis to generate noninferiority margins for 3 outcomes. DESIGN This was a mixed-methods study, including in-person interviews with patients and a Delphi process with physicians. SETTINGS North American patients and physicians participated. PATIENTS Consecutive patients undergoing colonoscopy, 40% of whom had a previous history of diverticulitis, were selected. INTERVENTIONS Informational video (for patients) and evidence summaries (for physicians) regarding antibiotics in diverticulitis were reviewed. MAIN OUTCOMES MEASURES Noninferiority margins were generated for time to reach full recovery, persistent diverticulitis, and progression to complicated diverticulitis in the context of a nonantibiotic strategy. Consensus was defined as an interquartile range <2.5. RESULTS Fifty patients participated in this study. To avoid antibiotics, patients were willing to accept up to 5.0 (3.0-7.0) days longer to reach full recovery, up to an absolute increase of 4.0% (4.0-6.0) in the risk of developing persistent diverticulitis, and up to an absolute increase of 2.0% (0-3.8) in the risk of progressing to complicated diverticulitis. A total of 55 physicians participated in the Delphi (round 1 response rate = 94.8%; round 2 response rate = 100%). Consensus noninferiority margins were generated for persistent diverticulitis (4.0%, 4.0-5.0) and progression to complicated diverticulitis (3.0%, 2.0-3.0), but could not be generated for time to reach full recovery (5.0 days, 3.5-7.0). LIMITATIONS Patients were recruited from a single institution, and Delphi participants were invited and not randomly selected. CONCLUSION Noninferiority margins were generated for 3 important outcomes after the treatment of acute uncomplicated diverticulitis in the context of a nonantibiotic strategy.

Abstract
Diverticular disease (DD) is an umbrella definition that includes different clinical conditions ranging from diverticulosis to severe and potentially life-threatening complications. In the last decade, new concepts regarding pathogenetic alterations have been developed, while the diagnostic, clinical and therapeutic approaches to the management of DD patients have changed. The protective role of dietary factors (i.e., fiber) has been questioned, whilst some drugs widely used in clinical practice have been found to have a deleterious effect. The use of antibiotics in all patients with acute uncomplicated diverticulitis was reconsidered, as well as the need for a surgical approach in these patients. Conflicting recommendations in different guidelines were proposed for the treatment of symptomatic uncomplicated DD. An endoscopic classification of DD was introduced, and a "curative" endoscopic approach has been pioneered. Based on these observations, which together amount to a kind of "Copernican revolution" in the management of DD patients, we performed a comprehensive and critical reappraisal of the proposed modifications, aiming to discriminate between certainties and doubts on this issue.

Abstract
PURPOSE Antibiotics are widely used in the treatment of uncomplicated left-sided colonic diverticulitis. In Asian countries, however, right-sided colonic diverticulitis is more common than left-sided colonic diverticulitis. The aim of the present study was to evaluate the need for antibiotics in the treatment of uncomplicated right-sided colonic diverticulitis in an Asian population. METHODS Patients were randomized to two management strategies: antibiotics and no antibiotics. At 4-6 weeks after discharge, the patients in both groups underwent computed tomography or were contacted by phone to confirm the effectiveness of the treatment. The primary end point was the treatment failure rate of the initial treatment, and secondary end points were the length of hospital stay and total admission costs. RESULTS Patients were randomized to treatment with (61 patients) or without (64 patients) antibiotics. The rates of treatment failure in the antibiotics and no antibiotics groups were 1.7% and 4.6%, respectively, with no significant difference (P = 0.619). There was also no significant difference in the length of hospital stay between the groups (P = 0.983). Total admission costs were lower in the no antibiotics group than in the antibiotics group (US$1004.70 vs US$1112.40, respectively, P = 0.037). CONCLUSION Conservative management of uncomplicated right-sided colonic diverticulitis without antibiotics shows similar treatment failure rates and length of hospital stay, and is associated with lower hospital costs, compared with standard antibiotic treatment. Therefore, conservative management can be considered as a safe treatment option. TRIAL REGISTRATION ClinicalTrial.gov No. NCT02314013.

Abstract
Background The aim of this study was to evaluate the risk of development of colorectal adenomas in patients with colorectal cancer (CRC) with and without colonic diverticulosis. Methods We performed a retrospective cohort study that included patients with CRC between 2008 and 2011. All patients underwent preoperative colonoscopic and barium enema examinations. Follow-up colonoscopic examinations were performed within 1 year and between 3 and 5 years postoperatively. The incidence of colorectal adenomas was compared based on the presence or absence of diverticulosis. Additionally, multivariate logistic regression analysis was performed to identify the factors independently associated with the development of synchronous and metachronous colorectal adenomas. Results Of the 168 patients with CRC included in the study, 55 showed colonic diverticulosis. Synchronous colorectal adenomas were more common in CRC patients with diverticulosis than in those without diverticulosis (P > 0.001). Multivariate regression analysis showed that colonic diverticulosis (odds ratio (OR) 3.874, 95% confidence interval (CI) 1.843–8.144, P > 0.001) and obesity (body mass index > 25.0 kg/m2, OR 2.395, 95% CI 1.089–5.270, P = 0.030) were associated with an increased risk of synchronous colorectal adenomas. The presence of synchronous colorectal adenomas increased the risk of metachronous colorectal adenomas (OR 4.407, 95% CI 1.855–10.473, P > 0.001). Conclusions Colonic diverticulosis was associated with synchronous colorectal adenomas in patients with CRC, which is eventually increasing the risk of metachronous adenomas.

Abstract
BACKGROUND Uncomplicated colonic diverticulitis is common. There is no consensus regarding the most appropriate management. Some authors have reported the efficacy and safety of observational management, and others have argued for a more aggressive approach with oral or intravenous antibiotic treatment. OBJECTIVE The purpose of this study was to perform an updated meta-analysis of the different management strategies for uncomplicated diverticulitis with 2 separate meta-analyses. DATA SOURCES MEDLINE, Embase, and Cochrane databases were used. STUDY SELECTION All randomized clinical trials, prospective, and retrospective comparative studies were included. INTERVENTIONS Observational and antibiotics treatment or oral and intravenous antibiotics treatment were included. MAIN OUTCOME MEASURES Successful management (emergency management, recurrence, elective management) was measured. RESULTS After review of 293 identified records, 11 studies fit inclusion criteria: 7 studies compared observational management and antibiotics treatment (2321 patients), and 4 studies compared oral and intravenous antibiotics treatment (355 patients). There was no significant difference between observational management and antibiotics treatment in terms of emergency surgery (0.7% vs 1.4%; p = 0.1) and recurrence (11% vs 12%; p = 0.3). In this part, considering only randomized trials, elective surgery during the follow-up occurred more frequently in the observational group than the antibiotic group (2.5% vs 0.9%; p = 0.04). The second meta-analysis showed that failure and recurrence rates were similar between oral and intravenous antibiotics treatment (6% vs 7% (p = 0.6) and 8% vs 9% (p = 0.8)). LIMITATIONS Inclusion of nonrandomized studies, identification of high risks of bias (selection, performance, and detection bias), and presence of heterogeneity between the studies limited this work. CONCLUSIONS Observational management was not statistically different from antibiotic treatment for the primary outcome of needing to undergo surgery. However, in patients being treated by antibiotics, our studies demonstrated that oral administration was similar to intravenous administration and provided lower costs. Although it may be difficult for physicians to do, there is mounting evidence that not treating uncomplicated colonic diverticulitis with antibiotics is a viable treatment alternative.

Abstract
INTRODUCTION Diverticulitis is a significant cause of morbidity among older women, and little attention has been paid to understanding its etiology. We have shown that menopausal hormone therapy (MHT) is associated with the risk of inflammatory bowel disease. In this study, we prospectively examined the association between MHT and the risk of incident diverticulitis. METHODS We studied 65,367 postmenopausal women enrolled in the Nurses' Health Study who provided detailed information on hormone use and other medical and lifestyle factors biennially, and on diet every 4 years. Between 2008 and 2014, participants reported any episodes of diverticulitis that required antibiotics and the date of occurrence. We used Cox proportional hazards regression models to estimate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS Over 24 years encompassing 1,297,165 person-years of follow-up, we documented 5,425 incident cases of diverticulitis. We observed an increased risk of diverticulitis among both current (HR 1.28; 95% CI 1.18-1.39) and past (HR 1.35; 95% CI 1.25-1.45) MHT users compared to never users. The increased risk was observed among participants using estrogen only (HR 1.30; 95% CI 1.20-1.41) and those using combined estrogen and progesterone (HR 1.31; 95% CI 1.21-1.42) compared to nonusers. The risk did not increase with longer duration of use (P-trend = 0.76). The association between MHT and diverticulitis was not modified by age, body mass index, past oral contraceptive use, or fiber intake (all P-interaction >0.11). CONCLUSIONS Menopausal hormone therapy was associated with an increased risk of diverticulitis. Further studies are needed to understand the potential mechanisms that may underlie this association.

Abstract
Frailty, which is a syndrome that encompasses losses in physical, psychological and social domains, is responsible for enhanced vulnerability to endogenous and/or exogenous stressors. Frailty is a public health problem for an ageing society; however, it is poorly understood and often under-recognised in clinical settings. In particular, the impact of frailty on either intestinal functions, i.e. immune response, permeability, and absorption, or gut microbiota composition is as yet mostly unexplored. A better comprehension of the intestinal dysfunction occurring in the elderly would help in clarifying the mechanisms predisposing frail patients to a higher risk of infectious or inflammatory events. Moreover, recent evidence suggests that senescence-induced perturbations of the gut-brain axis are involved in the neuroinflammation process, thus raising the hypothesis that preserving gut permeability and preventing frailty-related changes in the microbiota composition might reduce the susceptibility to develop neurodegenerative disorders. In this review, we highlight the current insights concerning the relationship between frailty, intestinal functions, microbiota, and gut-brain axis.

Abstract
BACKGROUND Diverticular disease is a common condition that increases in prevalence with age. Recent theories on the pathogenesis of diverticular inflammation have implicated chronic inflammation similar to that seen in ulcerative colitis. Mesalamine, or 5-aminosalicylic acid (5-ASA), is a mainstay of therapy for individuals with ulcerative colitis. Accordingly, 5-ASA has been studied for prevention of recurrent diverticulitis. OBJECTIVES To evaluate the efficacy of mesalamine (5-ASA) for prevention of recurrent diverticulitis. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 8), in the Cochrane Library; Ovid MEDLINE (from 1950 to 9 September 2017); Ovid Embase (from 1974 to 9 September 2017); and two clinical trials registries for ongoing trials - Clinicaltrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform database (9 September 2017).We also searched proceedings from major gastrointestinal conferences - Digestive Disease Week (DDW), United European Gastroenterology Week (UEGW), and the American College of Gastroenterology (ACG) Annual Scientific Meeting - from 2010 to September 2017. In addition, we scanned reference lists from eligible publications, and we contacted corresponding authors to ask about additional trials. SELECTION CRITERIA We included randomised controlled clinical trials comparing the efficacy of 5-ASA versus placebo or another active drug for prevention of recurrent diverticulitis. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as defined by Cochrane. Three review authors assessed eligibility for inclusion. Two review authors selected studies, extracted data, and assessed methodological quality independently. We calculated risk ratios (RRs) for prevention of diverticulitis recurrence using an intention-to-treat principle and random-effects models. We assessed heterogeneity using criteria for Chi2 (P < 0.10) and I2 tests (> 50%). To explore sources of heterogeneity, we conducted a priori subgroup analyses. To assess the robustness of our results, we carried out sensitivity analyses using different summary statistics (RR vs odds ratio (OR)) and meta-analytical models (fixed-effect vs random-effects). MAIN RESULTS We included in this review seven studies with a total of 1805 participants. We judged all seven studies to have unclear or high risk of bias. Investigators found no evidence of an effect when comparing 5-ASA versus control for prevention of recurrent diverticulitis (31.3% vs 29.8%; RR 0.69, 95% confidence interval (CI) 0.43 to 1.09); very low quality of evidence).Five of the seven studies provided data on adverse events of 5-ASA therapy. The most commonly reported side effects were gastrointestinal symptoms (epigastric pain, nausea, and diarrhoea). No significant difference was seen between 5-ASA and control (67.8% vs 64.6%; RR 0.98, 95% CI 0.91 to 1.06; P = 0.63; moderate quality of evidence), nor was significant heterogeneity observed (I2 = 0%; P = 0.50). AUTHORS' CONCLUSIONS The effects of 5-ASA on recurrence of diverticulitis are uncertain owing to the small number of heterogenous trials included in this review. Rates of recurrent diverticulitis were similar among participants using 5-ASA and control participants. Effective medical strategies for prevention of recurrent diverticulitis are needed, and further randomised, double-blinded, placebo-controlled trials of rigorous design are warranted to specify the effects of 5-ASA (mesalamine) in the management of diverticulitis.

Abstract
Increasing interest in diverticular disease by the scientific community in the last 10-15 years has resulted in an increased number of publications. Among other things, nonevidence-based therapeutic paradigms were tested in randomized, controlled therapy studies. The importance of surgery in the therapy of diverticulitis has diminished in recent years; in particular, it has no role in the treatment of diverticulitis types 1a, 1b, and 2a according to the Classification of Diverticular Disease (CDD) treated successfully by conservative means. Surgery has only a subordinate role in recurrent type 3b diverticulitis according to the CDD. Diverticulitis is therefore increasingly treated using conservative or drug therapy. However, only the classic, established antibiotics are currently available as effective drugs for the treatment of diverticular disease. However, these are also decreasing in significance. Over 90% of patients with type 1a/1b diverticulitis can be safely treated according to current data without the use of antibiotics. It is possible that type 2a diverticulitis will also be successfully treated without antibiotics in the future. Substances such as rifaximin, mesalazine, or probiotics, which were tested above all in patients with chronic recurrent forms (CDD type 3a/3b), have not yet been established.

Abstract
PURPOSE OF REVIEW The composition of activated adipose tissue with adipocytes secreting a broad spectrum of immune-modulatory adipokines next to adipose tissue-derived stromal cells and professional immune effector cells in the visceral fat creates a complex network of inflammatory processes shaping local immune responses in the adjacent inflamed intestinal mucosa. RECENT FINDINGS In Crohn's disease a particular phenomenon called 'creeping fat' can be observed. Here the hyperplastic mesenteric fat tissue not only grows around inflamed small intestinal segments but also furthermore affects the regulation of the mucosal immune system. Diverticular disease is highly prevalent in the western world but the knowledge about its immunopathology remains incomplete. Interestingly, adipose tissue also frequently covers the basolateral site of inflamed diverticula, hence locally reflecting the phenomenon seen in Crohn's disease. SUMMARY This review aims to summarize the current knowledge in which measures this intraabdominal fat participates in the regulation of intestinal inflammation with a particular focus on differences and possible parallels in Crohn's disease and diverticulitis. The available data allow for suggesting that each inflamed diverticula mechanistically reflects Crohn's disease on a miniature scale.

Pathophysiology and Therapeutic Strategies for Symptomatic Uncomplicated Diverticular Disease of the Colon. Dig Dis Sci 2016; 61:673-83.

Abstract
Colonic diverticulosis imposes a significant burden on industrialized societies. The current accepted causes of diverticula formation include low fiber content in the western diet with decreased intestinal content and size of the lumen, leading to the transmission of muscular contraction pressure to the wall of the colon, inducing the formation of diverticula usually at the weakest point of the wall where penetration of the blood vessels occurs. Approximately 20 % of the patients with colonic diverticulosis develop abdominal symptoms (i.e., abdominal pain and discomfort, bloating, constipation, and diarrhea), a condition which is defined as symptomatic uncomplicated diverticular disease (SUDD). The pathogenesis of SUDD symptoms remains uncertain and even less is known about how to adequately manage bowel symptoms. Recently, low-grade inflammation, altered intestinal microbiota, visceral hypersensitivity, and abnormal colonic motility have been identified as factors leading to symptom development, thus changing and improving the therapeutic approach. In this review, a comprehensive search of the literature regarding on SUDD pathogenetic hypotheses and pharmacological strategies was carried out. The pathogenesis of SUDD, although not completely clarified, seems to be related to an interaction between colonic microbiota alterations, and immune, enteric nerve, and muscular system dysfunction (Cuomo et al. in United Eur Gastroenterol J 2:413-442, 2014). Greater understanding of the inflammatory pathways and gut microbiota composition in subjects affected by SUDD has increased therapeutic options, including the use of gut-directed antibiotics, mesalazine, and probiotics (Bianchi et al. in Aliment Pharmacol Ther 33:902-910, 2011; Comparato et al. in Dig Dis Sci 52:2934-2941, 2007; Tursi et al. in Aliment Pharmacol Ther 38:741-751, 2013); however, more research is necessary to validate the safety, effectiveness, and cost-effectiveness of these interventions.

Abstract
INTRODUCTION Diverticulitis is a common surgical admission that presents with a wide range of symptoms and severity. Overall there has been a shift to conservative management practices, including the consideration of non-antibiotic treatment approaches in select cases. METHODS A national survey of all consultant surgeons evaluating their practices was performed. Reasons for changes in management, use of radiological imaging, role of non-antibiotic treatment approaches and indications for elective surgical management were evaluated. RESULTS Response rate for this survey was 67.7% (n = 67/99). An overwhelming 92.5% stated that computed tomography imaging was routinely used to investigate acute presentations. Interestingly, 22.4% stated they would consider a non-antibiotic treatment approach in uncomplicated diverticulitis. Main reasons for adopting this approach was low inflammatory markers with short duration of symptoms. Co-amoxiclav was the most common antibiotic used for acute diverticulitis, with considerable variability in duration of treatment. Additionally, there was considerable heterogeneity regarding how many recurrences were necessary before surgical management was required. CONCLUSION This review highlights substantial variation in the management of diverticulitis across Ireland. Shifts to non-antibiotic treatment approaches for uncomplicated cases are observed, but less so than in Northern Europe. National guidelines are required to establish uniform treatment protocols including indications for surgical resection.

Abstract
Acute diverticulitis is a common disease with increasing incidence. In most of cases, diagnosis is made at an uncomplicated stage offering a curative attempt under medical treatment and use of antibiotics. There is a risk of diverticulitis recurrence. Uncomplicated diverticulitis is opposed to complicated forms (perforation, abscess or fistula). Recent insights in the pathophysiology of diverticulitis, the natural history, and treatments have permitted to identify new treatment strategies. For example, the use of antibiotics tends to decrease; surgery is now less invasive, percutaneous drainage is preferred, peritoneal lavage is encouraged. Treatments of the diverticulitis are constantly evolving. In this review, we remind the pathophysiology and natural history, and summarize new recommendations for the medical and surgical treatment of acute diverticulitis.

Abstract
The statements produced by the Consensus Conference on Diverticular Disease promoted by GRIMAD (Gruppo Italiano Malattia Diverticolare, Italian Group on Diverticular Diseases) are reported. Topics such as epidemiology, risk factors, diagnosis, medical and surgical treatment of diverticular disease (DD) in patients with uncomplicated and complicated DD were reviewed by a scientific board of experts who proposed 55 statements graded according to level of evidence and strength of recommendation, and approved by an independent jury. Each topic was explored focusing on the more relevant clinical questions. Comparison and discussion of expert opinions, pertinent statements and replies to specific questions, were presented and approved based on a systematic literature search of the available evidence. Comments were added explaining the basis for grading the evidence, particularly for controversial areas.

Abstract
BACKGROUND Previous prospective studies have found the incidence of intestinal diverticular disease decreased with increasing intakes of dietary fibre, but associations by the fibre source are less well characterised. We assessed these associations in a large UK prospective study of middle-aged women. METHODS AND FINDINGS During 6 (SD 1) years follow-up of 690 075 women without known diverticular disease who had not changed their diet in the last 5 years, 17 325 were admitted to hospital or died with diverticular disease. Dietary fibre intake was assessed using a validated 40-item food questionnaire and remeasured 1 year later in 4265 randomly-selected women. Mean total dietary fibre intake at baseline was 13.8 (SD 5.0) g/day, of which 42% came from cereals, 22% from fruits, 19% from vegetables (not potatoes) and 15% from potatoes. The relative risk (95% CI) for diverticular disease per 5 g/day fibre intake was 0.86 (0.84 to 0.88). There was significant heterogeneity by the four main sources of fibre (p<0.0001), with relative risks, adjusted for each of the other sources of dietary fibre of 0.84 (0.81 to 0.88) per 5 g/day for cereal, 0.81 (0.77 to 0.86) per 5 g/day for fruit, 1.03 (0.93 to 1.14) per 5 g/day for vegetable and 1.04 (1.02 to 1.07) per 1 g/day for potato fibre. CONCLUSIONS A higher intake of dietary fibre is associated with a reduced risk of diverticular disease. The associations with diverticular disease appear to vary by fibre source, and the reasons for this variation are unclear.

Abstract
Disease-specific variations in intestinal microbiome composition have been found for a number of intestinal disorders, but little is known about diverticulitis. The purpose of this study was to compare the fecal microbiota of diverticulitis patients with control subjects from a general gastroenterological practice and to investigate the feasibility of predictive diagnostics based on complex microbiota data. Thirty-one patients with computed tomography (CT)-proven left-sided uncomplicated acute diverticulitis were included and compared with 25 control subjects evaluated for a range of gastrointestinal indications. A high-throughput polymerase chain reaction (PCR)-based profiling technique (IS-pro) was performed on DNA isolates from baseline fecal samples. Differences in bacterial phylum abundance and diversity (Shannon index) of the resulting profiles were assessed by conventional statistics. Dissimilarity in microbiome composition was analyzed with principal coordinate analysis (PCoA) based on cosine distance measures. To develop a prediction model for the diagnosis of diverticulitis, we used cross-validated partial least squares discriminant analysis (PLS-DA). Firmicutes/Bacteroidetes ratios and Proteobacteria load were comparable among patients and controls (p = 0.20). The Shannon index indicated a higher diversity in diverticulitis for Proteobacteria (p < 0.00002) and all phyla combined (p = 0.002). PCoA based on Proteobacteria profiles resulted in visually separate clusters of patients and controls. The diagnostic accuracy of the cross-validated PLS-DA regression model was 84 %. The most discriminative species derived largely from the family Enterobacteriaceae. Diverticulitis patients have a higher diversity of fecal microbiota than controls from a mixed population, with the phylum Proteobacteria defining the difference. The analysis of intestinal microbiota offers a novel way to diagnose diverticulitis.

Abstract
INTRODUCTION Diverticular disease (DD) of the colon is a widespread disease, which shows worldwide increasing incidence and represents a significant burden for National Health Systems. The current guidelines claim that symptomatic uncomplicated DD (SUDD) has to be treated with spasmolithics and high-fiber diet, whereas both uncomplicated and complicated acute diverticulitis has to be treated with antibiotics. However, new physiopathological knowledge suggests that further treatment may be promising. AREAS COVERED Pathogenetic and treatment studies on SUDD and acute diverticulitis published in PubMed, www.clinicaltrials.gov , and in the main International Congress were reviewed. EXPERT OPINION Although absorbable antibiotics and 5-aminosalycilic acid seem to be effective in treating SUDD, their role in preventing diverticulitis recurrence is still under debate. Antibiotic use in managing acute diverticulitis is at least questionable, and use of probiotics seems to be promising but need further robust studies to confirm the preliminary results.

Abstract
Diverticulosis and diverticular disease are a common problem in daily practice and one third of the patients with diverticulosis develop symptoms. Patients with uncomplicated diverticulitis are very often treated with antibiotics. There is growing evidence that antibiotics are not necessary in uncomplicated cases. One problem is the different classification of diverticulitis and diverticular disease. Therefore, it is not easy to compare different studies. The evidence for therapy with antibiotics, mesalamine, probiotics and fibers are initially discussed and secondly therapeutic recommendations are given for the various stages of diverticular disease.

Abstract
BACKGROUND Diverticular disease (DD) and irritable bowel syndrome (IBS) share a similar symptom pattern. However, comparative studies are flawed by different age at onset of symptoms. We aimed to verify whether clinical features distinguish DD from IBS. MATERIALS AND METHODS Patients with DD or IBS, matched for age and gender (1/1) were consecutively recruited. Data on demographic parameters, voluptuary habits, inheritance of disease and symptoms were collected. Moreover, the association between pain > 24 h, and clinical parameters were evaluated. RESULTS Ninety patients with DD and 90 patients with IBS (DD: F/M: 46/44; age: 50.9 years; IBS: 46/44; 50.4) were selected from an overall population of 1275 patients. Only nine patients with DD (10%) fulfilled the criteria for IBS diagnosis. Abdominal pain > 24 h was more prevalent in SDD than in patients with IBS (20 vs. 6 patients; P < 0.01). Furthermore, compared with IBS, patients with DD showed more episodes of pain > 24 h requiring medical attention (80% vs. 33%; P < 0.01). CONCLUSIONS Abdominal pain lasting for more than 24 h discriminates patients with DD compared with those with IBS. Identifying this symptom could be an appropriate strategy to define the diagnosis and management.

Abstract
Acute diverticulitis of the colon represents a significant burden for national health systems, in terms of direct and indirect costs. Past guidelines claimed that recurrent episodes (two or more) of diverticulitis need surgery, but revised guidelines recommend an individualized approach to patients after an attack of acute diverticulitis. For these reasons, conservative treatment has become the preferred choice after an episode of diverticulitis. Thus, significant efforts are now being focused to identify the correct therapeutic approach to prevent diverticulitis relapses. Nonabsorbable antibiotics, 5-aminosalicylic acid and probiotics are currently being investigated in this way. The effectiveness and the future perspectives of these treatments are discussed herein.

Abstract
BACKGROUND AND AIM Recurrence of diverticulitis is frequent within 5 years from the uncomplicated first attack, and its prophylaxis is still unclear. We have undertaken a multicentre, randomised, double-blind, placebo-controlled pilot study in order to evaluate the role of mesalazine in preventing diverticulitis recurrence as well as its effects on symptoms associated to diverticular disease. METHODS Ninety-six patients with the recent first episode of uncomplicated diverticulitis were randomised to receive mesalazine 800 mg twice daily for 10 days every month or placebo for 24 months. The primary efficacy end point was the diverticulitis recurrence at intention to treat analysis. Clinical evaluations were performed using the Therapy Impact Questionnaire (TIQ) for physical condition and quality of life at admission and at 3-month intervals. Treatment tolerability and routine biochemistry parameters as well as the use of additional drugs were also evaluated. RESULTS Ninety-two patients (mean age, 61.5) completed the study, 45 of whom received mesalazine, and 47, placebo. Diverticulitis relapse incidence in mesalazine-treated group was 5/45 (11%) at the 12th month and 6/45 (13%) at the 24th month; in the placebo-treated group, the correspondent rates were 13% (6/47) and 28% (13/47), respectively. Mean values of TIQ at 24 months were significantly better in mesalazine-treated group than in placebo-treated group (p = 0.02); in addition, average additional drug consumption was significantly lower (-20.4%, p < 0.03) in mesalazine than in placebo. CONCLUSIONS Diverticulitis recurrence occurred in as many as 28% of patients under placebo within 24 months from the initial episode. Intermittent prophylaxis with mesalazine did not significantly reduce the risk of relapse but induced a significant improvement of patients' physical conditions and significantly lowered the additional consumption of other gastrointestinal drugs.

Abstract
BACKGROUND Placebo-controlled studies in maintaining remission of symptomatic uncomplicated diverticular disease (SUDD) of the colon are lacking. AIM To assess the effectiveness of mesalazine and/or probiotics in maintaining remission in SUDD. METHODS A multicentre, double-blind, placebo-controlled study was conducted. Two hundred and ten patients were randomly enrolled in a double-blind fashion in four groups: Group M (active mesalazine 1.6 g/day plus Lactobacillus casei subsp. DG placebo), Group L (active Lactobacillus casei subsp. DG 24 billion/day plus mesalazine placebo), Group LM (active Lactobacillus casei subsp. DG 24 billion/day plus active mesalazine), Group P (Lactobacillus casei subsp. DG placebo plus mesalazine placebo). Patients received treatment for 10 days/month for 12 months. Recurrence of SUDD was defined as the reappearance of abdominal pain during follow-up, scored as ≥5 (0: best; 10: worst) for at least 24 consecutive hours. RESULTS Recurrence of SUDD occurred in no (0%) patient in group LM, in 7 (13.7%) patients in group M, in 8 (14.5%) patients in group L and in 23 (46.0%) patients in group P (LM group vs. M group, P = 0.015; LM group vs. L group, P = 0.011; LM group vs. P group, P = 0.000; M group vs. P group, P = 0.000; L group vs. P group, P = 0.000). Acute diverticulitis occurred in six group P cases and in one group L case (P = 0.003). CONCLUSION Both cyclic mesalazine and Lactobacillus casei subsp. DG treatments, particularly when given in combination, appear to be better than placebo for maintaining remission of symptomatic uncomplicated diverticular disease. (ClinicalTrials.gov: NCT01534754).

Abstract
Diverticulosis is one of the most common gastrointestinal conditions affecting the general population in the Western world. It is estimated that over 2.5 million people are affected by diverticular disease in the United States. The spectrum of clinical manifestations of diverticulosis ranges from asymptomatic diverticulosis to complicated diverticulitis. Treatment for symptomatic diverticular disease is largely based on symptoms. Traditional therapy includes fiber, bowel rest, antibiotics, pain control and surgery for selected cases. This review discusses recent advances in the medical treatment of diverticular disease such as the use of mesalamine, rifaximin and probiotics as our understanding of the disease evolves.

Abstract
BACKGROUND Gut mast cells represent an important cell population involved in intestinal homeostasis and inflammatory processes. However, their possible role has not to date been investigated in colonic diverticular disease. AIMS This study aims to evaluate colonic mast cells in patients undergoing surgery for diverticular disease. METHODS Surgical resection samples from 27 patients undergoing surgery for diverticular disease (12 emergency procedures for severe disease and 15 elective procedures) were evaluated. The number of mast cells was assessed in the various layers by means of a specific antibody (tryptase) and compared with those evaluated in ten controls. In patients with mast cells degranulation, double immunohistochemistry, also assessing nerve fibres, was carried out. In addition, the presence of myenteric plexitis was sought. RESULTS Compared with controls, the number of mast cells in diverticular patients was significantly increased, both as an overall figure and in the various layers of the large bowel. In patients in whom mast cells degranulation was present, these were always closed to nerve fibres. No differences were found between the two subgroups of patients with respect to the number and distribution of mast cells; however, all patients undergoing emergency surgery (but none of those undergoing elective procedures) had myenteric plexitis, represented by lymphocytic infiltration in 67 % and eosinophilic infiltration in 33 % of cases. CONCLUSIONS Patients with diverticular disease display an increase of mast cells in the large bowel. The presence of myenteric plexitis in those with complicated, severe disease, suggest that this could represent a histopathologic marker of more aggressive disease.

Abstract
Diverticular disease imposes a significant burden on Western and industrialized societies. The traditional pathogenesis model posits that low dietary fiber predisposes to diverticulosis, and fecalith obstruction prompts acute diverticulitis that is managed with broad-spectrum antibiotics or surgery. However, a growing body of knowledge is shifting the paradigm of diverticular disease from an acute surgical illness to a chronic bowel disorder composed of recurrent abdominal symptoms and considerable psychosocial impact. New research implicates a role for low-grade inflammation, sensory-motor nerve damage, and dysbiosis in a clinical picture that mimics irritable bowel syndrome (IBS) and even inflammatory bowel disease (IBD). Far from being an isolated event, acute diverticulitis may be the catalyst for chronic symptoms including abdominal pain, cramping, bloating, diarrhea, constipation, and "post-diverticulitis IBS." In addition, studies reveal lower health-related quality of life in patients with chronic diverticular disease vs. controls. Health-care providers should maintain a high index of suspicion for the multifaceted presentations of diverticular disease, and remain aware that it might contribute to long-term emotional distress beyond traditional diverticulitis attacks. These developments are prompting a shift in therapeutic approaches from widespread antimicrobials and supportive care to the use of probiotics, mesalamine, and gut-directed antibiotics. This review addresses the emerging literature regarding epidemiology, pathophysiology, and management of chronic, symptomatic diverticular disease, and provides current answers to common clinical questions.

Abstract
The aim of this work was to compare the recurrence of diverticulitis during a 5-year follow-up in a population of patients affected by symptomatic uncomplicated diverticular disease (SUDD), taking either 800 mg of mesalamine b.i.d for 10 days every month or no 5-ASA. Sixty-seven consecutive patients affected by SUDD followed-up every 6 months for 5 years. All patients in this group (M-group) were requested to consume mesalamine 800 mg b.i.d for 10 days every month. A control group (C-group) of 82 subjects with SUDD allocated in an institution for the elderly and taking no 5-ASA medications was also followed-up for the same period. As a result in the M-group 14.9% of patients did not complete the follow-up, and diverticulitis developed in two patients (4%; 95% CI 1.1-13.5). In the C-group 6.1% patients did not complete the follow-up, and diverticulitis developed in 8 patients (10.4%; 95% CI 5.4-19.2). The difference between the two groups was not significant (difference = -6.4%; 95% CI -15.6 to 4.3; log rank test: p = 0.1256). Cyclic treatment with mesalazine seems to be clinical, although not statistically effective in reducing the incidence of diverticulitis. In future well-designed RCTs are necessary to demonstrate the therapeutic gain of the use of mesalazine, if any, in the management of patients with SUDD.

Abstract
AIM Conservative treatment of mild colonic diverticulitis usually consists of observation, restriction of oral intake, intravenous fluids and antibiotics. The beneficiary effect of antibiotics remains unclear. The aim of this study is to evaluate the need for antibiotics in mild colonic diverticulitis. METHOD A retrospective case-control study was performed in 272 patients with mild colonic diverticulitis admitted to two hospitals with distinctly different treatment regimes concerning antibiotic use. RESULTS A total of 191 patients were treated without antibiotics and 81 with antibiotics. Groups were comparable at baseline with respect to age, sex, comorbidity, and use of nonsteroid anti-inflammatory drugs, steroids and aspirin. All patients had imaging-confirmed diverticulitis. C reactive protein and white blood count levels did not differ significantly. In the antibiotics group there were significantly more patients with a temperature of 38.5°C or higher on admission. (8 vs 19%; P=0.014). Treatment failure did not differ between groups (4 vs 6%; P=0.350). The risk of recurrence was higher in the antibiotics group on logistic regression analysis but did not reach statistical significance (odds ratio, 2.04; confidence interval, 0.88-4.75; P=0.880). The only factor that increased the risk of recurrence was nonsteroid anti-inflammatory drug use (odds ratio, 7.25; confidence interval, 1.22-46.88; P=0.037). CONCLUSION Antibiotics can be omitted in selected patients with mild colonic diverticulitis and should be given on indication only.

Abstract
Colonic diverticular disease is one of the most common gastrointestinal disorders in the Western world, affecting approximately 50% of the population above the age of 70 years. Symptoms develop only in about one quarter of the affected individuals with complications in one-third of the symptomatic patients. Diagnosis is mostly confirmed by colonoscopy. Abdominal CT is the most sensitive for the diagnosis of complicated severe diverticulitis, while colonoscopy or in severe cases angiography may be performed in bleeding patients. Initial therapy of non-complicated symptomatic diverticulitis includes antibiotics and more recently non-absorbable antibiotics. In complicated cases should be treated with broad spectrum i.v. antibiotics, however surgery may became necessary in a minority of the cases. The proportion of patients needing acute surgical intervention has decreased in the last decades with the advancement of conservative management including medical therapy, endoscopy and imaging techniques and the indication of elective was also changed.

Abstract
BACKGROUND The standard of care for acute uncomplicated diverticulitis today is antibiotic treatment, although there are no controlled studies supporting this management. The aim was to investigate the need for antibiotic treatment in acute uncomplicated diverticulitis, with the endpoint of recovery without complications after 12 months of follow-up. METHODS This multicentre randomized trial involving ten surgical departments in Sweden and one in Iceland recruited 623 patients with computed tomography-verified acute uncomplicated left-sided diverticulitis. Patients were randomized to treatment with (314 patients) or without (309 patients) antibiotics. RESULTS Age, sex, body mass index, co-morbidities, body temperature, white blood cell count and C-reactive protein level on admission were similar in the two groups. Complications such as perforation or abscess formation were found in six patients (1·9 per cent) who received no antibiotics and in three (1·0 per cent) who were treated with antibiotics (P = 0·302). The median hospital stay was 3 days in both groups. Recurrent diverticulitis necessitating readmission to hospital at the 1-year follow-up was similar in the two groups (16 per cent, P = 0·881). CONCLUSION Antibiotic treatment for acute uncomplicated diverticulitis neither accelerates recovery nor prevents complications or recurrence. It should be reserved for the treatment of complicated diverticulitis.

Abstract
AIM The study aimed to investigate current management strategies for left-sided diverticulitis and compare them with current international guidelines. Differences between surgeons and gastroenterologists and between gastrointestinal and nongastrointestinal surgeons were assessed. METHOD A web-based survey of treatment options for uncomplicated and complicated diverticulitis was carried out among surgeons and gastroenterologists in the Netherlands. Only surgeons were asked about surgical strategy. RESULTS A total of 292 surgeons and 87 gastroenterologists responded, representing 92% of all surgical and 46% of all gastroenterology departments. Ninety per cent of respondents treated mild diverticulitis without antibiotics. About one-fifth (18% gastroenterologists; 19% surgeons) regarded a CT scan as mandatory in the initial assessment. Most surgeons and gastroenterologists used some form of bowel rest, would consider outpatient treatment and would perform a colonoscopy on follow up. For Hinchey Stage 3, 78% of surgeons would consider resection and primary anastomosis and laparoscopic lavage was viewed as a valid alternative by 30% of gastrointestinal and 2% of nongastrointestinal surgeons. For Hinchey stage 4, 46% of gastrointestinal and 72% of nongastrointestinal surgeons would always perform Hartmann's procedure. CONCLUSION The treatment of diverticulitis in the Netherlands shows major differences when compared with guidelines for all stages of disease.

Abstract
Diverticular disease is a common bowel condition, the pathogenesis of which is incompletely understood. Acute exacerbations of diverticular disease usually require dietary changes, antibiotic therapy, and may necessitate urgent surgery. Approximately 25-33% of patients experience symptomatic and acute inflammatory disease recurrence, suggesting that current long-term management is inadequate. Because inflammatory complications of diverticular disease, including diverticulitis, are similarities to inflammatory bowel diseases, evidence suggests that patients may respond to anti-inflammatory therapies used in these conditions. Here, we explore the rationale and evidence for use of inflammatory bowel disease treatment, namely 5-aminosalicylic acid (5-ASA; mesalamine), in diverticular disease, and review clinical data on the efficacy of mesalamine either alone or in combination with other agents for the treatment of diverticular disease. PubMed and conference abstracts were searched for clinical studies examining the use of mesalamine in treating diverticular disease. Studies were evaluated for treatment efficacy in symptom reduction, recurrence prevention, or improving quality of life. The results of our search suggest that single-agent mesalamine can reduce diverticular disease symptoms and improve quality of life more effectively than antibiotic treatment alone. Mesalamine in combination with antibiotics can also reduce symptoms and improve quality of life with greater efficacy than either treatment alone. Combining mesalamine and probiotics treatments may reduce recurrent attacks of diverticular disease. Further randomized, well-controlled studies are required for validation; however, it seems that mesalamine is an important agent in future diverticular disease management.

Abstract
BACKGROUND The value of antibiotics in the treatment of acute uncomplicated left-sided diverticulitis is not well established. The aim of this review was to assess whether or not antibiotics contribute to the (uneventful) recovery from acute uncomplicated left-sided diverticulitis, and which types of antibiotic and route of administration are most effective. METHODS Medline, the Cochrane Library and Embase databases were searched. Randomized controlled trials (RCTs), prospective or retrospective cohort studies addressing conservative treatment of mild uncomplicated left-sided diverticulitis and use of antibiotics were included. RESULTS No randomized or prospective studies were found on the topic of effect on outcome. One retrospective cohort study was retrieved that compared a group treated with antibiotics with observation alone. This study showed no difference in success rate between groups. Only one RCT of moderate quality compared intravenous and oral administration of antibiotics, and found no differences. One other RCT of very poor quality compared two different kinds of intravenous antibiotic and also found no difference. A small retrospective cohort study comparing antibiotics with and without anaerobe coverage showed no difference in group outcomes. CONCLUSION Evidence on the use of antibiotics in mild or uncomplicated diverticulitis is sparse and of low quality. There is no evidence mandating the routine use of antibiotics in uncomplicated diverticulitis, although several guidelines recommend this. Copyright © 2011 British Journal of Surgery Society Ltd.

Abstract
BACKGROUND Acute uncomplicated diverticulitis (AUD) may show histologic and serologic signs of inflammation. GOALS To assess whether serologic markers of inflammation may be predictive of abnormal histology in AUD. STUDY Twenty-one consecutive patients affected by AUD were studied (15 Males, 6 Females, mean age 66.19 y, range 43 to 85 y). Diagnosis of AUD was based on specific endoscopic and CT scan patterns. Several serologic markers were assessed [White blood cells (WBC), Erytro-sedimentation Rate, C-reactive protein (CRP), fibrinogen, α1-acid glycoprotein]. Neutrophilic and lymphocytic inflammatory infiltrate was also scored. RESULTS WBC was increased in 4/21 pts (19.4%), Erytro-sedimentation Rate in 12/21 pts (57.14%), CRP in 13/21 pts (61.9%), fibrinogen in 5/21 pts (23.8%), and α1-acid glycoprotein in 6/21 pts (28.57%). All serologic markers were related with the degree of histologic damage. In patients scoring 3 in neutrophilic infiltrate (severe active inflammation), all markers showed a statistical significant relation (ranging from P=0.004 for WBC to P=0.00001 for fibrinogen). CRP was the most sensitive marker of mild-moderate histologic damage, as it was increased in 4/10 (40%) patients scoring 0 or 1 in neutrophilic infiltrate (absence of mild active inflammation) (P=0.005). CONCLUSIONS Serologic markers showed a strict relation with the degree of histologic damage in AUD. Moreover, CRP is the most sensitive marker of mild-moderate histologic damage.

Abstract
OBJECTIVES A subset of patients with colonic diverticular disease have chronic gastrointestinal symptoms, and some have a clinical diagnosis of irritable bowel syndrome (IBS), but whether IBS and diverticular disease are linked is uncertain. We aimed to evaluate this association in the community. METHODS A population-based, cross-sectional survey was conducted by mailing a valid symptom questionnaire to the eligible residents of Olmsted County, MN, aged 30-95 years. Colonic diverticular disease (diverticulosis and diverticulitis) was ascertained through a review of the complete medical history of all responders. Subjects with at least one relevant test (colonoscopy, computed tomography (CT) scan, CT colonography, or barium enema) were included. IBS was defined using Rome II criteria. RESULTS Among 2,267 eligible respondents, there were 1,712 subjects who had undergone colon testing (76%): 919 women (54%); mean (+/-s.d.) age 65 (+/-11 years). Colonic diverticular disease was identified in 44.4% (95% confidence interval (CI) 42.1-46.8) of the subject. IBS was reported by 8.8% (95% CI 6.9-11.0) of men and 17.0% (95% CI 14.6-19.6) of women. After adjusting for age and gender, the presence of IBS was associated with an increased odds for diverticulosis (odds ratio (OR) =1.8, 95% CI 1.3-2.4) but not diverticulitis (OR=1.7, 95% CI 0.9-3.2). In those 65 years of age or older, the presence of IBS was associated with a ninefold higher odds for diverticulosis (OR=9.4, 95% CI 5.8-15.1). Relative to the non-IBS subgroup, diarrhea-predominant IBS and mixed IBS were significantly associated with an increased odds for diverticular disease (OR=1.9, 95% CI 1.1-3.2; OR=2.6, 95% CI 1.0-6.4, respectively). CONCLUSIONS There is a significantly increased odds for colonic diverticulosis in subjects with IBS (relative to those without IBS). These results suggest that IBS and colonic diverticular disease may be connected.

Abstract
Formation of colonic diverticula, via herniation of the colonic wall, is responsible for the development of diverticulosis. When diverticulosis becomes symptomatic, it becomes diverticular disease. Diverticular disease is common in Western and industrialized countries, and it is associated with numerous abdominal symptoms (including pain, bloating, nausea, diarrhea, and constipation). Standard medical therapies with antibiotics are currently recommended for patients affected by diverticular disease. However, changing concepts on the pathophysiology of the disease suggest that diverticular disease may share many of the hallmarks of inflammatory bowel diseases. On this basis, the addition of therapies using mesalazine and probiotics may enhance treatment efficacy by shortening the course of the disease and preventing recurrences.
