World J Gastrointest Pharmacol Ther 2022; 13:57-66. [PMID: 36051180 PMCID: PMC9297289 DOI: 10.4292/wjgpt.v13.i4.57] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 04/27/2022] [Accepted: 05/28/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Low bone mineral density (BMD) is common in patients with inflammatory bowel disease. However, nutritional risk factors for low BMD in the ulcerative colitis (UC) population are still poorly understood.
AIM To investigate the association of anthropometric indicators and body composition with BMD in patients with UC.
METHODS This is a cross-sectional study on adult UC patients of both genders who were followed on an outpatient basis. A control group consisting of healthy volunteers, family members, and close people was also included. The nutritional indicators evaluated were body mass index (BMI), total body mass (TBM), waist circumference (WC), body fat in kg (BFkg), body fat in percentage (BF%), trunk BF (TBF), and also lean mass. Body composition and BMD assessments were performed by dual-energy X-ray absorptiometry.
RESULTS The sociodemographic characteristics of patients with UC (n = 68) were similar to those of healthy volunteers (n = 66) (P > 0.05). Most patients (97.0%) were in remission of the disease, 58.8% were eutrophic, 33.8% were overweight, 39.0% had high WC, and 67.6% had excess BF%. However, mean BMI, WC, BFkg, and TBF of UC patients were lower when compared to those of the control group (P < 0.05). Reduced BMD was present in 41.2% of patients with UC (38.2% with osteopenia and 2.9% with osteoporosis) and 3.0% in the control group (P < 0.001). UC patients with low BMD had lower BMI, TBM, and BFkg values than those with normal BMD (P < 0.05). Male patients were more likely to have low BMD (prevalence ratio [PR] = 1.86; 95% confidence interval [CI]: 1.07-3.26). Those with excess weight (PR = 0.43; 95%CI: 0.19-0.97) and high WC (PR = 0.44; 95%CI: 0.21-0.94) were less likely to have low BMD.
CONCLUSION Patients with UC in remission have a high prevalence of metabolic bone diseases. Body fat appears to protect against the development of low BMD in these patients.

Risk Factors for Worsening of Bone Loss in Patients Newly Diagnosed with Inflammatory Bowel Disease. Gastroenterol Res Pract 2022; 2022:1498293. [PMID: 35419052 PMCID: PMC9001094 DOI: 10.1155/2022/1498293] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Accepted: 02/23/2022] [Indexed: 11/17/2022] Open
Abstract
Background. Bone loss is common in patients with inflammatory bowel disease (IBD). The aim of the present study was to determine the prevalence of metabolic bone disease in patients newly diagnosed with IBD and to identify the risk factors for bone loss over time. Methods. We performed a retrospective, both cross-sectional and longitudinal, study to extract the risk factors of bone loss (including osteopenia and osteoporosis) in patients newly diagnosed with IBD, using dual-energy X-ray absorptiometry (DXA). Results. A total of 639 patients newly diagnosed with IBD that had at least one DXA were included in the cross-sectional study. Osteopenia and osteoporosis were diagnosed in 24.6% and 5.4% of patients, respectively. Age at diagnosis, body mass index, and serum phosphorus were identified as independent factors associated with bone loss at baseline. A total of 380 of the 639 IBD patients (including 212 CD patients and 168 UC patients) with at least a second DXA scan were included in the longitudinal study. 42.6% of the patients presented a worsening of bone loss in the follow-up study. Menopause, albumin, and use of corticosteroids were identified as independent factors associated with worsening of bone loss. Conclusions. Metabolic bone disease is common in IBD patients, and there is a significant increase in prevalence of bone loss over time. Postmenopausal female, malnourished patients, and those requiring corticosteroid treatment are at risk for persistent bone loss. Therefore, BMD measurements and early intervention with supplementation of calcium and vitamin D are recommended in IBD patients with high-risk factors.

Abstract
PURPOSE OF REVIEW Patients with inflammatory bowel disease (IBD) are not receiving preventative care services at the same rate as the general population. IBD patients are at increased risk for infections, osteoporosis, and certain malignancies secondary to their disease and as they are on immunosuppressive therapy. They are a younger population and often times consider their gastroenterologist as their primary care physician. In this review, we discuss up-to-date evidence pertaining to vaccine-preventable illnesses in the immunosuppressed IBD patient, screening for bone health, cervical cancer, skin malignancies, psychological wellbeing, and smoking cessation. RECENT FINDINGS Vaccinations are recommended in the IBD population as they are immunosuppressed and at increased risk for acquiring influenza and pneumonia. Not only are they at greater risk to acquire it but they also have a much severe complicated course. Ideally, IBD patients should be vaccinated prior to initiating immunosuppression and most inactive vaccines can be administered to them while they are on therapy. All IBD patients should be encouraged to stop smoking and have adequate vitamin D intake along with appropriate applicable cancer screenings. Gastroenterologists must work in collaboration with primary care providers along with other specialists to help provide our patients well-rounded care for their IBD.

Abstract
Inflammatory bowel disease (IBD) is associated with low bone mineral density (BMD). In this study, the association between disease severity and BMD in patients with IBD was evaluated. Associations between BMD and the Montreal classification, disease activity and drug therapy were also tested. A cross-sectional prevalence study with a comparison group was conducted. One hundred and twenty-eight patients were evaluated: 68 patients with ulcerative colitis (UC), and 60 with Crohn's disease (CD). The control group consisted of 67 healthy subjects. All patients and controls had BMD measured and in IBD patients, current medications, hospitalization, and disease location, extent and phenotype, according to the Montreal classification, were recorded. Multiple correspondence analysis was applied to evaluate categorical variables. In the CD group, most patients were diagnosed between 17–40 years of age. Ileocolonic and non-stricturing non-penetrating disease were the most frequent disease location and behavior, respectively. In UC patients, extensive colitis was the most frequent disease location. UC and CD patients were more likely to have osteopenia than controls (OR=14.93/OR=24.38, respectively). In the CD group, male patients, perianal disease, penetrating behavior and age at diagnosis >40 years were associated with low BMD. Taking azathioprine and infliximab also seemed to be associated with osteopenia. In the UC group, we observed an association between low BMD and male patients, left colitis, corticosteroid use and hospitalization. Disease activity was not associated with osteopenia or osteoporosis in CD and UC patients. Disease severity seems to be associated with osteopenia in IBD patients.

Abstract
BACKGROUND Our previous study showed that nephrolithiasis is a common complication in ulcerative colitis patients after ileal pouch anal anastomosis (IPAA). However, the pathogenesis of nephrolithiasis in IPAA patients has not been studied. The aim of this study was to compare urine and serum metabolic compositions in IPAA patients with nephrolithiasis and controls with IPAA and no nephrolithiasis. METHODS Using cross-sectional study design, serum and 24-hour urine metabolic compositions were compared between IPAA patients with nephrolithiasis (the study group) and those without (the control group). Urinary supersaturation of calcium oxalate, calcium phosphate, and uric acid was calculated. RESULTS A total of 40 patients were enrolled in the study. There were no significant differences in serum electrolytes, vitamin D, parathyroid hormone, and kidney function tests between the study (n = 20) and control groups (n = 20). Patients in the study group were found to have a significantly higher 24-hour urine supersaturation of calcium oxalate (8.8 versus 5.0, P = 0.037) and calcium phosphate (0.61 versus 0.27, P = 0.028) as compared with controls. Nineteen (95%) patients in the study group were symptomatic due to nephrolithiasis with several requiring procedural intervention for treatment, including ureteroscopy in 3 (15%) patients, lithotripsy in 5 (25%) patients, and percutaneous surgery in 1 (5%) patient. CONCLUSIONS Ulcerative colitis-IPAA patients are at risk for the development of calcium oxalate and calcium phosphate stones. Nephrolithiasis is symptomatic in a majority of the patients and frequently requires procedural intervention for treatment.

Abstract
Inflammatory bowel disease (IBD) patients exhibit higher risk for bone loss than the general population. The chronic inflammation causes a reduction in bone mineral density (BMD), which leads to osteopenia and osteoporosis. This article reviewed each risk factor for osteoporosis in IBD patients. Inflammation is one of the factors that contribute to osteoporosis in IBD patients, and the main system that is involved in bone loss is likely RANK/RANKL/osteoprotegerin. Smoking is a risk factor for bone loss and fractures, and many mechanisms have been proposed to explain this loss. Body composition also interferes in bone metabolism and increasing muscle mass may positively affect BMD. IBD patients frequently use corticosteroids, which stimulates osteoclastogenesis. IBD patients are also associated with vitamin D deficiency, which contributes to bone loss. However, infliximab therapy is associated with improvements in bone metabolism, but it is not clear whether the effects are because of inflammation improvement or infliximab use. Ulcerative colitis patients with proctocolectomy and ileal pouches and Crohn’s disease patients with ostomy are also at risk for bone loss, and these patients should be closely monitored.

Abstract
PURPOSE OF REVIEW Pouchitis, representing a spectrum of disease phenotypes, is the most common long-term complication in patients who have undergone restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Its management and prevention are challenging. RECENT FINDINGS Treatment modalities vary according to phenotypes of pouchitis. The medical therapy of pouchitis remains largely empiric and antibiotic-based. However, patients may develop de-novo chronic antibiotic-refractory pouchitis (CARP) or progress from acute antibiotic-responsive phenotype. Patients with CARP often require alternative medical approaches to routine antibiotics, including the use of oral or topical mesalazine, corticosteroids, and sometimes immunomodulators or biological agents against tumour necrosis factor. There are two strategies to prevent pouchitis, the primary (i.e., the prevention of the initial episode) and secondary (i.e., the prevention of recurrent episodes) prophylaxis. There are scant data in the literature on nutritional aspects. SUMMARY We evaluated the efficacy of current strategies of prevention and treatments of pouchitis and propose algorithms, including attention to nutrition wherein data exist.

Abstract
BACKGROUND Clostridium difficile infection (CDI) might contribute to a refractory course of pouchitis. However, the association between preoperative CDI and postoperative CDI in ileal pouch patients has not been investigated. AIM Our study aimed to evaluate whether preoperative CDI had an impact on the occurrence of postoperative CDI in pouch patients. METHODS Consecutive eligible ileal pouch patients from February 2005 to December 2012 were identified from the Pouchitis Registry at the Cleveland Clinic. Patients in the registry with known status of CDI of the pouch were surveyed with a structured questionnaire regarding preoperative C. difficile test and its treatment. Medical records were also reviewed. Demographics and clinical characteristics and outcomes were evaluated with univariable and multivariable analyses. RESULTS A total of 102 patients with preoperative C. difficile test were identified for this study and 21 patients (20.6%) tested positive for C. difficile test after colectomy. In logistic regression analysis, male patients were 7.85 (P = 0.003) times more likely to have CDI than women. In addition, preoperative significant comorbidities (P = 0.037) and preoperative use antibiotics for other indications (P = 0.005) were found to be associated with postoperative CDI of the pouch. However, there was no evidence to suggest that the preoperative CDI was associated with the occurrence of postoperative CDI (P = 0.769). CONCLUSIONS Postoperative CDI occurred frequently in male patients with IPAA. In addition, preoperative comorbidities and antibiotic use were found to be risk factors for CDI of the pouch. However, preoperative CDI did not appear to be associated with an increased risk for postoperative CDI in pouch patients.

Abstract
Low bone mineral density (BMD) or low bone mass is common in patients with inflammatory bowel disease (IBD). Studies have shown that low BMD is also common in patients with ulcerative colitis (UC) even after colectomy and ileal pouch–anal anastomosis (IPAA). The reported frequency of osteopenia ranged from 26–55% and that of osteoporosis ranged from 13–32% in patients with IPAA. Increasing age, low body mass index, lack of calcium supplementation and high inflammatory activity with villous atrophy in the ileo-anal pouch are risk factors for low bone mass in pouch patients. Bone loss is also common in patients with IBD and ostomy. Current professional society guidelines do not specifically address the need for surveillance in patients with ileal pouches or ostomy. A growing body of evidence suggests that patients with ileal pouch or ostomy are at an increased risk of bone loss. Pending prospective studies, screening and surveillance using dual energy X-ray absorptiometry (DEXA) along with calcium/vitamin D supplementation may be beneficial in those patients.

Abstract
PURPOSE OF REVIEW To provide a synopsis on established and new research evaluating bone disease in patients with inflammatory bowel disease (IBD). RECENT FINDINGS Persons with IBD, including Crohn's disease and ulcerative colitis are believed to be at high risk for osteoporosis and fracture. As osteoporosis is clinically silent and persons with IBD are not universally screened, the burden of bone disease in IBD has been difficult to accurately assess. It is also unclear whether bone disease is due to inflammatory activity, medication use, poor nutrient intake/absorption, or body habitus characteristics. Recent studies using population-wide databases of bone mineral density (BMD) analyses suggest that Crohn's disease is responsible for a small effect on BMD after adjusting for other risk factors for low BMD, whereas ulcerative colitis does not appear to confer an independent risk. Furthermore, IBD does not appear to be a risk for overall fracture once controlling for factors which are associated with both IBD and fracture risk. The ability to assess BMD on incidentally performed computed tomography scans may allow detection of low BMD in IBD patients. SUMMARY Although reduced BMD and fracture are more common in persons with IBD, the precise burden is not well characterized. Also, the relative impact of IBD-associated factors and IBD-specific inflammation on bone health is still uncertain.

Abstract
BACKGROUND Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the preferred surgical treatment for ulcerative colitis (UC). Little is known of how the operation affects bone metabolism and fracture risk. The aim of this retrospective cohort study was to investigate fracture risk and serum markers of bone metabolism following IPAA in a national cohort of Danish UC patients. METHODS Diagnostic codes for 1757 patients and 8785 controls were obtained from the National Patient Register while blood results were collected from a regional database. Postoperative fracture free survival was evaluated on a Kaplan-Meier plot. Fracture hazard ratios (HR) after IPAA were calculated from Cox proportional hazards regression analysis. RESULTS Fracture risk after IPAA was significantly reduced (adjusted HR = 0.49, 95% CI: 0.43; 0.55, p<0.001). Prior fractures and alcoholism independently increased fracture risk significantly. Osteoporotic fracture risk after IPAA was reduced, significantly for wrist fractures (aHR = 0.39, 95% CI: 0.22; 0.71, p = 0.002), and borderline insignificantly for spine fractures (aHR = 0.51, 95% CI: 0.26; 1.01, p = 0.054). Vitamin D and calcium levels were significantly higher in the patient group (61.2 nmol/L vs. 58.9 nmol/L, p = 0.04 and 1.24 mmol/L vs. 1.21 mmol/L, p<0.01, respectively), while parathyroid hormone and phosphate levels were significantly lower (4.9 pmol/L vs. 6.2 pmol/L, p<0.01 and 1.08 mmol/L vs. 1.12 mmol/L, p<0.01, respectively). CONCLUSION Fracture risk after IPAA is significantly reduced compared to the general population. Prospective studies are needed to verify the biochemical results.

Abstract
BACKGROUND Bone loss in patients with inflammatory bowel disease (IBD) with ostomy has not been systemically studied. The aims of the study were to evaluate the frequency, risk factors, and sequelae of bone loss in patients with IBD and stomas and to monitor the change in bone mineral density (BMD) over time after ostomy. METHODS A total of 126 patients met the inclusion criteria (i.e., those with IBD diagnosis and stoma), including ileostomy (N = 120), colostomy (N = 3), and jejunostomy (N = 3). BMD was measured on dual-energy X-ray absorptiometry (DEXA). Patients were classified as having normal or low BMD based on the International Society for Clinical Densitometry criteria. Thirty-two demographic and clinical variables were evaluated with logistic regression models. RESULTS At a median of 6.6 years (interquartile range, 2-18.7 yr) after stoma, 37 (29.4%) patients had a low BMD. On univariate analysis, there were no significant differences between the normal and low BMD groups in the following variables: gender, race, age at diagnosis of IBD, prevalence of Crohn's disease and ulcerative colitis, age at ostomy, duration from diagnosis to DEXA and from ostomy to DEXA, menopausal age, diabetes, hypothyroidism, renal stones, short bowel syndrome, history of smoking or excessive alcohol use, family history of IBD or osteoporosis, daily calcium and vitamin D supplement, estrogen replacement, and steroid use. Body mass index was significantly lower in the low BMD group than the normal BMD group (23.3 ± 5.5 versus 26.0 ± 5.2, P = 0.013). Fragility fracture occurred in 8 (21.6%) patients in low BMD group and 4 (4.5%) patients in normal BMD group (P = 0.006). In a multivariate analysis, low body mass index was the only covariate-adjusted factor associated with low BMD. In patients with multiple DEXA scans available over time after ostomy, hip BMD was found to improve marginally, and the lumbar and femoral BMD remained stable. CONCLUSIONS Low BMD was common in patients with IBD after ostomy, largely based on the findings in patients with CD with ileostomy. Fragility fracture was 5 times more frequent in patients with ostomy with low BMD compared with those with normal BMD. The low BMD was associated with a low body mass index. Screening and surveillance of BMD should routinely be performed, particularly in these patients at risk. Bone mass tends to stabilize over time after stoma.

Abstract
BACKGROUND Vitamin D (25(OH) D3) levels in pouch patients are not well defined. AIM To evaluate the frequency and factors associated with low 25(OH) D3 levels in pouch patients with underlying inflammatory bowel disease (IBD). METHODS A consecutive of 157 pouch patients was identified from our Pouchitis Registry. A sample of 155 ulcerative colitis (UC) patients without IPAA served as controls. RESULTS The mean age of the cohort was 37.5 ± 14.2 years, with 86 (54.8%) being female. Low 25(OH)D3 levels (<31 ng/mL) were detected in 69.4% of patients (N=109). 34 (21.7%) of the 157 patients examined were 25(OH)D3 deficient (<20 ng/mL). This was higher than the frequency of vitamin D insufficiency or deficiency in a sample of UC patients without IPAA. Between patients with and without normal 25(OH) D3 levels (>31 ng/mL), no differences were identified in terms of demographic, pouch, and medication variables. A low hemoglobin level was found to be associated with low 25(OH) D3 levels in both univariate (p=0.02) and multivariate analyses (odds ratio [OR]=3.37; 95% confidence interval [CI]: 1.41-8.06; p=0.01). Low levels of 25(OH)D3 was not related to markers of pouch inflammation, in particular there was no relation to pouchitis (OR=1.20; 95% CI: 0.41-3.52; p=0.74). CONCLUSION Low 25(OH)D3 level was common in this cohort, irrespective of inflammation of the pouch, possibly suggesting a strategy of routine testing in this population. Anemia was found to be associated with a low 25(OH)D3 level.

Abstract
Ileal pouch-anal anastomosis (IPAA) is a classical surgery for ulcerative colitis patients. However, knowledge on trace element alteration in patients who had undergone this surgery is limited. This study was conducted to assess trace element alteration in patients with ulcerative colitis before and after ileal pouch-anal anastomosis. Preoperative (40) and postoperative (35) ulcerative colitis patients were studied. The dietary assessment of trace element intake was undertaken by a semiquantitative food frequency questionnaire. Patients' trace element status of zinc, copper, manganese, selenium, calcium, iron, and vitamin D3 was assessed by measuring their blood concentrations. We found that with the similar dietary intake, there was no statistical difference in the concentrations of plasma copper, iron, calcium, and vitamin D3 in the two groups (P > 0.05). Compared with preoperative patients, postoperative patients had higher concentrations of plasma zinc (14.51 ± 4.75 μmol/l) and manganese (0.21 ± 0.11 μmol/l) and lower concentrations of plasma selenium (0.86 ± 0.58 μmol/l). Both preoperative and postoperative mean concentrations of plasma calcium and vitamin D3 were below their reference range, respectively. We conclude that IPAA does not seem to alter patients' abnormal trace elements completely. It is important to monitor and supply some specified trace elements even in postoperative patients.

Abstract
Extra-intestinal manifestations (EIMs) are reported frequently in patients with inflammatory bowel disease (IBD) and may be diagnosed before, concurrently or after the diagnosis of IBD. EIMs in IBD may be classified based on their association with IBD disease activity. The first group has a direct relationship with the activity of the bowel disease and includes pauciarticular arthritis, oral aphthous ulcers, erythema nodosum and episcleritis. The second group of EIMs appears to follow an independent course from the underlying bowel disease activity and include ankylosing spondylitis and uveitis. The third group includes EIMs that may or may not be related to intestinal inflammation, such as pyoderma gangrenosum and probably primary sclerosing cholangitis (PSC). Genetic susceptibility, aberrant self-recognition and immunopathogenic autoantibodies against organ-specific cellular antigens shared by the colon and extra-colonic organs may contribute to the pathogenesis and development of these EIMs. The use of biological agents in the IBD armamentarium has expanded the treatment options for some of the disabling EIMs and these agents form the cornerstone in managing most of the disabling EIMs. PSC is one of the most common hepatobiliary manifestations associated with IBD in which no clear treatment options exist other than endoscopic therapy and liver transplantation. Future research targeting the pathogenesis, early diagnosis and treatment of these EIMs is required.

Abstract
BACKGROUND AND AIMS Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become a standard of care in patients with ulcerative colitis (UC). Nephrolithiasis is common in patients with inflammatory bowel disease (IBD), but has never been studied as a complication of IPAA. We aimed to assess the risk factors for nephrolithiasis in patients with IPAA. METHODS Using an IRB-approved, prospectively maintained pouch registry, we identified 1221 patients between 2000 and 2010. Those with post-IPAA nephrolithiasis served as the study group whereas IPAA patients without nephrolithiasis served as the controls. Demographic and clinical variables were analyzed using multivariable logistic regression to identify risk factors. RESULTS There were a total of 218 IPAA patients: 81 with nephrolithiasis (37%) and 137 without (63%). Of the 81 patients in the study group, 17 were excluded due to limited clinical data. Three risk factors were found to be associated with nephrolithiasis: the presence of extra-intestinal manifestations (odd's ratio [OR]=2.9, 95% confidence interval [CI]: 1.4, 5.8, p=0.003), no use of antibiotics (OR=3.2, 95% CI: 1.5, 6.5, p=0.002) and low serum bicarbonate level (OR=0.87, 95% CI: 0.77, 0.99, p=0.038). CONCLUSION Nephrolithiasis was a common finding in our patients with IPAA. As pouch patients with nephrolithiasis can develop adverse clinical complications, those with at least one of the risk factors we identified may need to be monitored more closely and possibly receive prophylactic treatment with oral bicarbonate.

Abstract
IPAA is a technically demanding procedure that requires appropriate skills and expertise. Adverse sequelae of IPAA are common. Accurate diagnosis and classification of pouch disorders and associated complications are important for proper management and prognosis. Based on presenting symptoms, appropriate and combined diagnostic modalities should apply. A multidisciplinary approach involving gastroenterologists, colorectal surgeons, gastrointestinal pathologists, and gastrointestinal radiologists is advocated for diagnosis and treatment of pouch disorders.

Abstract
BACKGROUND Inflammatory complications of ileal pouch-anal anastomosis (IPAA), including pouchitis and Crohn's disease (CD) of the pouch, are common in patients with restorative proctocolectomy for ulcerative colitis. It is not clear whether these inflammatory conditions can affect upper GI tract. The aim of the study was to evaluate correlation between duodenal and pouch histology in patients with healthy and diseased pouches. METHODS All IPAA patients who had esophagogastroduodenoscopy with biopsy after colectomy (N = 96) were included. H&E slides of gastric, duodenal, neo-terminal ileum, and pouch body biopsies were blindly re-reviewed by an expert GI pathologist for acute and chronic inflammation. Demographic and clinical variables and pouch outcome were analyzed. RESULTS There was a significant correlation between acute inflammation in the duodenum as measured by neutrophil infiltration score and the presence of chronic pouchitis (kappa coefficient = 0.21, P < 0.05). Intraepithelial lymphocytosis of the duodenum, though uncommon, only occurred in patients with irritable pouch syndrome, chronic pouchitis, or CD of the pouch. Crypt distortion of duodenal epithelium was only seen in patients with inflammatory or structural diseases of the pouch, including acute (18.2%) and chronic (5%) pouchitis, CD of the pouch (14.3%), and surgical complications of the pouch (14.4%). CONCLUSION Histologic evaluation of duodenal biopsy may provide additional information in patients with ileal pouches, as patients with normal histology of the pouch may have an abnormal duodenal histology.

Abstract
Osteoporosis is a leading cause of morbidity in patients with inflammatory bowel disease (IBD). Bone loss is an early systemic process and occurs even before clinical disease manifests. Bone disease is attributed to vitamin D deficiency, steroid use, and/or systemic inflammation. In this review, we discuss the molecular pathways of bone loss mediated by inflammatory cytokines and other mediators. Further research will hopefully clarify the mechanisms of inflammation-induced bone loss in IBD and guide effective treatment modalities.

Abstract
BACKGROUND AND AIM Patients with ulcerative colitis (UC) are at an increased risk for low bone mineral density (BMD). It is unclear whether proctocolectomy with ileal pouch-anal anastomosis (IPAA) for UC alters the risk of bone loss. The aim of this study was to compare BMD in UC patients with and without IPAA. METHODS A total of 267 patients with UC and IPAA (study group) were compared to 119 UC patients without IPAA (control group) in this cross-sectional study. The demographic and clinical variables including dual-energy X-ray absorptiometry scan results were compared. Patients were classified as having normal or low BMD, based on the criteria by the International Society for Clinical Densitometry. Univariate and multivariate analyses were performed to assess risk factors associated with low BMD. Age, gender, race, smoking status, steroid use, alcohol use, body mass index, years of absent estrogen protection, use of calcium, vitamin D supplements and disease duration were selected as covariates. RESULTS 83 (31.1%) had low BMD in the study group vs. 18 (15.1%) in the control group (p=0.001). 2/13 (15.4%) had low BMD before surgery. The mean age of patients in the study and control groups were 44.7 ± 14.1 vs. 52.4 ± 17.7 years, respectively (p<0.001). The hip BMD was lower in the study group (0.93 ± 0.17 g/cm2) than that in the control group (0.98 ± 0.17 g/cm2) (p=0.038). Fragility fracture was documented in 23 (8.6%) patients in the study group vs. 3 (2.5%) in the control group (p=0.038) Sixty-four (24.0%) of the study group patients were using corticosteroids after surgery in contrast to 93 (78.2%) in the control group (p<0.001). On multivariable analyses, covariate adjusted factors associated with a low BMD in UC patients were advanced age [odds ratio (OR) 1.51 per 5 years; 95% confidence interval [CI], 1.34-1.71], low body mass index (OR=2.37 per 5 kg/m(2) decrease; 95% CI, 1.68-3.36), and the presence of IPAA (OR=6.02; 95% CI, 2.46-14.70). For the 13 IPAA patients who had information available, BMD before IPAA was low. After a median of 46 (Range 7-84) months after IPAA, BMD improved in 7/13 patients (53.8%), while it continued to be low in 6/13 (46.2%) patients. CONCLUSIONS Low BMD is common in patients with UC. The risk appears to persist even after colectomy and IPAA surgery suggesting that these patients need to be monitored for bone loss.

Abstract
BACKGROUND Ulcerative colitis (UC) and increasing age are associated with an increased risk of osteoporosis. Screening of postmenopausal women and men older than 50 years with ulcerative colitis for osteoporosis is recommended. The prevalence of osteoporosis in restorative proctocolectomy (RPC) patients more than 50 years old is not known. METHODS Fifty-three consecutive patients older than age 50 who had undergone RPC for UC underwent a bone density scan (DXA). Sex, smoking status, age at diagnosis of UC, duration of UC, age at RPC, years since RPC, age at DXA, and pouch histological inflammatory score were recorded. The Kruskal-Wallis test and Spearman's correlation coefficient were used to analyze the data. RESULTS Fifty-three patients were studied; their median age was 58 years, and the median age at RPC was 45. The prevalence of osteopenia and osteoporosis was 43.4% and 13.2%, respectively. Age at RPC was negatively correlated with bone density (P = 0.041, r = 0.281), and there was a negative correlation approaching significance with age at the time of DXA (P = 0.071, r = -0.250). No other factor studied correlated with bone density. CONCLUSIONS The prevalence of osteoporosis and osteopenia found in this study is similar to that reported for UC patients who have not undergone RPC. Patients having RPC should be screened in line with current UC guidelines, targeting those older than 50 years.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for patients with medically refractory ulcerative colitis (UC) or UC-associated dysplasia, and for the majority of patients with familial adenomatous polyposis. Pouchitis and other complications of IPAA are common. There are scant data on laboratory markers for the evaluation and diagnosis of pouch disorders. The presence of immunogenotypic markers such as genetic polymorphisms of interleukin-1 (IL-1) receptor antagonist, NOD2/CARD15, Toll-like receptor, and tumor necrosis factor-alpha has been reported to be associated with pouchitis. Immunophenotypic/serologic markers such as perinuclear antineutrophil cytoplasmic antibody and anti-CBir1 have been investigated as possible markers for predicting and diagnosing pouchitis. Fecal markers including lactoferrin and calprotectin seem to be useful in distinguishing inflammatory from noninflammatory pouch disorders. In our practice, we have encountered a large number of pouch patients with Clostridium difficile infection. Laboratory evaluation provides information on the etiology and pathogenesis of pouchitis, and it also helps practicing clinicians with accurate diagnosis, differential diagnosis, disease stratification, and management of ileal pouch disorders.
