RESUMO
Colonic diverticulosis and diverticular disease are among the most common gastrointestinal disorders encountered in clinical practice. These Italian guidelines focus on the diagnosis and management of diverticulosis and diverticular disease in the adult population, providing practical and evidence-based recommendations for clinicians. Experts from five Italian scientific societies, constituting a multidisciplinary panel, conducted a comprehensive review of meta-analyses, systematic reviews, randomised controlled trials, and observational studies to formulate 14 PICO questions. The assessment of the quality of the evidence and the formulation of the recommendations were carried out using an adaptation of the GRADE methodology. The guidelines covered the following topics: i) Management of diverticulosis; ii) Symptomatic uncomplicated diverticular disease: diagnosis and treatment; iii) Acute diverticulitis: diagnosis and treatment; iv) Management of diverticular disease complications; v) Prevention of recurrent acute diverticulitis; vi) Interventional management of diverticular disease.
RESUMO
BACKGROUND: Portal vein thrombosis (PVT) is a common complication of cirrhosis and can be a cause or consequence of liver disease progression. It is unclear whether PVT treatment is affecting clinical outcomes in cirrhotics. METHODS: This is a multicenter study of cirrhotics with PVT, initially retrospectively and thereafter prospectively registered in a data base. We studied the impact of PVT treatment on this population for efficacy, safety and the impact on survival. In survival analysis Mantel-Cox and Wilcoxon-Breslow-Gehan tests were used. A P value of <0.05, was considered significant. For statistical computations the STATA 12.1 was used. RESULTS: Seventy-six patients were included (76% decompensated, median MELD score 12 and Child-Pugh score 7), 47% with concomitant HCC. Fifty-one patients with PVT were treated with Vitamin-K antagonists or Low-Molecular-Weight Heparin. Patients were followed up for at least 6 months after PVT diagnosis, or until death or transplantation. PV patency after 6 months was not statistically different between patients receiving or not anticoagulation (complete-partial recanalization 27.4% of treated vs. 20% of untreated, P=0.21). Median survival was statistically worse between patients treated with anticoagulation than those untreated (10 vs. 15 months, P=0.036). Less portal hypertensive bleeding and less decompensation rates were found in treated cirrhotics vs. untreated (45.8% vs. 54.2%, P=0.003 and 78% vs. 80.9%, P=0.78, respectively). Patients with HCC had worse survival when treated vs. untreated (P=0.047). CONCLUSIONS: In our cohort of cirrhotics with PVT, treatment was feasible with acceptable side effects, but without meaningful clinical benefits.

BACKGROUND: Hereditary colorectal cancer syndromes require timely endoscopic surveillance. METHODS: This study evaluated the approach of Italian gastroenterologists to the management of such patients. It then assessed the impact of SARS-CoV-2. All members affiliated with the leading Italian gastroenterology societies (AIGO, SIED, and SIGE) received an online questionnaire. RESULTS: One hundred and twenty-one clinicians from 96 centers answered, not necessarily experts in the field (mean age 50.26 ± 11.22 years). Many collected family history for genetic risk assessment (74.4%), but only 14.0% used an online predictive software. 65.6% discussed cases in multidisciplinary units. Genetic analysis was available to most centers, but only a few hospitals offered dedicated endoscopy (19.0%), outpatient clinics (33.9%), or surgeries (23.1%). Since the start of the SARS-CoV-2 pandemic, the number of clinicians with a high volume of patients decreased (from 38.8% to 28.1%). Almost half of the responders (45.5%) reported a delay in the surveillance (median: 4-12 months). Ultimately, 30.6% detected one interval colorectal cancer in at least one of their patients. CONCLUSION: The SARS-CoV-2 pandemic directly affected the surveillance of hereditary colorectal cancer syndromes in Italy. Endoscopic surveillance should resume in all centers to avoid the possible long-term consequences of its interruption, especially for inherited colorectal cancer syndromes.

BACKGROUND: A relevant number of adenomas can be missed during colonoscopy. AIMS: Assess the current status of colonoscopy procedures in Italian centers. METHODS: A prospective observational study involving 17 hospitals (34 endoscopists) included consecutive patients undergoing standard colonoscopy. In the first phase, endoscopists performed consecutive colonoscopies. In the second phase, retraining via an online learning platform was planned, while in the third phase data were collected analogously to phase 1. RESULTS: A total of 3,504 patients were enrolled. Overall, a BBPS score ≥6 was obtained in 95.6% of cases (94.8% and 96.9% in the pre- and post-training phases, respectively). 88.4% of colonoscopies had a withdrawal time ≥6 min (88.2% and 88.7% in the pre- and post-training phases). Median adenoma detection rate (ADR) was 39.1%, with no significant differences between the pre- and post-training phases (40.1% vs 36.9%; P = 0.83). In total, 81% of endoscopists had a ADR performance above the 25% threshold. CONCLUSION: High colonoscopy quality standards are achieved by the Italian hospitals involved. Quality improvement initiatives and repeated module-based colonoscopy-training have been promoted in Italy during the last decade, which appear to have had a significant impact on quality colonoscopy metrics together with the activation of colorectal cancer screening programs.

In randomized clinical trials, no survival benefit has been observed for selective internal radiation therapy (SIRT) over sorafenib in patients with advanced hepatocellular carcinoma (HCC). This study aimed to assess, through a metaanalysis, whether overall survival (OS) with SIRT, as monotherapy or followed by sorafenib, is noninferior to sorafenib and to compare safety profiles for patients with advanced HCC. Methods: We searched MEDLINE, EMBASE, and the Cochrane Library up to February 2019 to identify randomized clinical trials comparing SIRT, as monotherapy or followed by sorafenib, with sorafenib monotherapy among patients with advanced HCC. The main outcomes were OS and frequency of treatment-related severe adverse events (≥grade 3). The per-protocol population was the primary analysis population. A noninferiority margin of 1.08 in terms of hazard ratio was prespecified for the upper boundary of 95% confidence interval for OS. Prespecified subgroup analyses were performed. Results: Three randomized clinical trials, involving 1,243 patients, comparing sorafenib with SIRT (SIRveNIB and SARAH) or SIRT followed by sorafenib (SORAMIC), were included. After randomization, 411 of 635 (64.7%) patients allocated to SIRT and 522 of 608 (85.8%) allocated to sorafenib completed the studies without major protocol deviations. Median OS with SIRT, whether or not followed by sorafenib, was noninferior to sorafenib (10.2 and 9.2 mo [hazard ratio, 0.91; 95% confidence interval, 0.78-1.05]). Treatment-related severe adverse events were reported in 149 of 515 patients (28.9%) who received SIRT and 249 of 575 (43.3%) who received sorafenib only (P < 0.01). Conclusion: SIRT as initial therapy for advanced HCC is noninferior to sorafenib in terms of OS and offers a better safety profile.

Alcohol use disorder which includes alcohol abuse and dependence represents one of the leading risk factors for premature mortality in Europe and it is responsible of over 200 conditions, including neuropsychiatric disorders, chronic diseases, cancers and accidents leading to permanent disability. Alcohol use disorder represents the most common cause of liver damage in the Western world, with a wide spectrum of diseases ranging from steatosis, steatohepatitis, fibrosis, cirrhosis and cancer. The present clinical practice guidelines by the Italian Association for the Study of the Liver (AISF) are focused on the current knowledge about epidemiology, pathophysiology, clinical features, diagnosis and treatment of alcohol associated liver disease, aiming to provide practical recommendations on the management of this complex pathological condition.

BACKGROUND/AIMS: Small intestinal bacterial overgrowth (SIBO) diagnosis is usually based on non-invasive breath tests (BTs), namely lactulose BT (LBT) and glucose BT (GBT). However, divergent opinions and problems of parameter standardization are still controversial aspects. We aim to perform a meta-analysis to analyze diagnostic performance of LBT/GBT for SIBO diagnosis. METHODS: We searched in main literature databases articles in which SIBO diagnosis was achieved by LBT/GBT in comparison to jejunal aspirate culture (reference gold standard). We calculated pooled sensitivity, specificity, positive, and negative likelihood ratios and diagnostic odd ratios. Summary receiver operating characteristic curves were drawn and pooled areas under the curve were calculated. RESULTS: We selected 14 studies. Pooled sensitivity of LBT and GBT was 42.0% and 54.5%, respectively. Pooled specificity of LBT and GBT was 70.6% and 83.2%, respectively. When delta over baseline cut-off > 20 H2 parts per million (ppm) was used, GBT sensitivity and specificity were 47.3% and 80.9%; when the cutoff was other than and lower than > 20 ppm, sensitivity and specificity were 61.7% and 86.0%. In patients with abdominal surgery history, pooled GBT sensitivity and specificity gave the impression of having a better performance (81.7% and 78.8%) compared to subjects without any SIBO predisposing condition (sensitivity = 40.6% and specificity = 84.0%). CONCLUSIONS: GBT seems to work better than LBT. A cut-off of delta H2 expired other than and lower than > 20 ppm shows a slightly better result than > 20 ppm. BTs demonstrate the best effectiveness in patients with surgical reconstructions of gastrointestinal tract.
RESUMO
BACKGROUND AND AIMS: Increasing literature data show that adherence to the Mediterranean diet is undergoing profound changes in recent years, albeit with marked differences across nations. In Italy, one of the cradles of the Mediterranean diet, the literature regarding the trend for Mediterranean diet adherence is conflicting. Thus, we aimed to explore the trends of adherence to the Mediterranean diet in a large cohort of participants living in South Italy, over 20 years from 1985-86 to 2005-06. METHODS AND RESULTS: Cross-sectional study with two evaluations, one made in 1985-86 and another in 2005-06; all participants were adults aged 30-70 years of age. The adherence to the Mediterranean diet was evaluated using the score proposed by Panagiotakos et al. This score features values ranging from 0 to 55, higher scores reflecting a greater adherence. The data are reported by age (30-49 vs. 50-69 years). Overall, 2451 subjects were included in 1985-86 and 2375 in 2005-06. A significant reduction was observed in the adherence to the Mediterranean diet (age 30-49 years: 31.82 ± 4.18 in 1985-86 vs. 29.20 ± 4.48 in 2005-06, reduction by 8.2%, p < 0.0001; age 50-69: 32.20 ± 4.09 in 1985-86 vs.30.15 ± 4.27 in 2005-06, reduction by 6.3%, p < 0.0001). Among all these items, the most dramatic change was observed for olive oil consumption, that decreased by 2.35 points in younger and 0.89 in older people. CONCLUSION: The adherence to the Mediterranean diet decreased from 1985-86 to 2005-06 in South Italy, particularly in younger people, above all due to a decreased olive oil consumption.

Aberrant function of Smad2, a crucial member of transforming growth factor beta (TGF-ß) signaling, is associated with the development of malignancies, particularly in the gastrointestinal district. However, little is known about its possible prognostic role in such tumor types. With the first meta-analysis on this topic, we demonstrated that the lack of the activated form of Smad2 (phosphor-Smad2 or pSmad2), which was meant to be the C-terminally phosphorylated form, showed a statistically significant association with an increased risk of all-cause mortality in patients with gastrointestinal cancers (RR, 1.58; 95% CI, 1.05-2.37, p = 0.029, I2 = 84%), also after having adjusted for potential confounders (RR, 1.65; 95% CI, 1.24-2.18; p < 0.001; I2 = 4%). This finding highlights the importance of the TGF-ß signaling in this type of cancer. In this line, further studies are needed to explore more in depth this important molecular pathway, focusing also on potential therapeutic strategies based on its effectors or molecular targets.

OBJECTIVE: Alcoholic fatty liver (AFLD) and non-alcoholic fatty liver (NAFLD) are two common conditions. However, if they can increase the risk of death is poorly explored. We therefore aimed to investigate the potential association between the presence and severity of liver steatosis and mortality in a large sample of older people. DESIGN: Prospective. SETTING: Community. PARTICIPANTS: Women and men randomly sampled from the electoral rolls of the population of Castellana Grotte, a town in Southern Italy (Apulia region) between 2005 and 2006. Among 1942 initially contacted, 1708 (=87.9%) participated to the baseline survey (Multicentrica Colelitiasi III (MICOL III)). This specific study included 1445 older participants (mean age=65.2 years, females=44.2%). EXPOSURE: NAFLD or AFLD. PRIMARY AND SECONDARY OUTCOMES: Mortality (all-cause and specific-cause). RESULTS: After a median of 12 years, 312 participants (=21.6%) died. After adjusting for nine potential confounders, the presence of steatosis was not associated with any increased risk of death in both NAFLD and AFLD. The severity of liver steatosis was not associated with any increased risk of mortality in NAFLD, while in AFLD, the presence of moderate steatosis significantly increased the risk of overall (HR=2.16; 95% CI 1.19 to 3.91) and cancer-specific (HR=3.54; 95% CI 1.16 to 10.87) death. CONCLUSIONS: Liver steatosis is not associated with any increased risk of death in NAFLD, while moderate steatosis could be a risk factor for mortality (particularly due to cancer) in people affected by AFLD.

BACKGROUND/AIMS: Post-liver transplant (LT) metabolic syndrome (PTMS) and cardiovascular (CVS) mortality are becoming increasingly prevalent following sustained improvements in post-LT survival. We investigated the prevalence and predictors of PTMS and CVS complications in a cohort of consecutive LT recipients. METHODS: We reviewed prospectively collected data of patients (n = 928) who underwent LT (1995-2013) and survived at least 1-year post-LT or died before that due to a major CVS complication. RESULTS: Median follow-up was 85 months (IQR = 106). The prevalence of PTMS was 22.4% and it developed de novo in 183 recipients (19.7%). A total of 187 (20.2%) patients developed at least one CVS event post-LT within a median of 49 months (IQR = 85). Overall mortality rate was 22.6% (n = 210). Causes of death were CVS events (n = 45, 21.4%), malignancies (21%), liver-related deaths (20%) and infections (6.7%). Independent predictors of major CVS events were: documented CVS disease pre-LT (Hazard Ratio (HR) = 3.330; 95% CI = 1.620-6.840), DM (HR = 1.120; 95% CI 1.030-1.220), hypertension (HR = 1.140; 95% CI 1.030-1.270), dyslipidaemia (HR = 1.140; 95% CI 1.050-1.240) and creatinine levels at 1 year (HR = 1.010; 95% CI = 1.005-1.013). Among LT recipients without pre-LT CVS disease or MS components (n = 432), 85 recipients developed ≥1 CVS events (19.7%) with independent predictors being DM (HR = 1.150; 95% CI = 1.010-1.320), creatinine levels at 1 year (HR = 1.020; 95% CI = 1.010-1.030) and hypertension (HR = 1.190; 95% CI = 1.040-1.360). CONCLUSIONS: Post-LT patients are at increased risk of CVS morbidity even in the absence of pre-existing metabolic risk factors. Renal sparing immunosuppressive protocols might reduce CVS events post-LT.

BACKGROUND: Unresectable gastric or pancreatic malignancies are the most common cause of gastric outlet obstruction (GOO). Although several authors reported better outcomes in patients submitted to gastric partitioning gastrojejunostomy (GPGJ) compared to conventional gastrojejunostomy (CGJ), clinical experience with GPGJ is poor, studies comparing the two techniques are few and no randomized trials were performed. Our systematic review aimed at comparing GPGJ (partial or complete) with CGJ in patients operated for GOO for gastric or pancreatic cancer. METHODS: A computerized literature search was performed on Medline until January 2017. The studies included were 8 with a total of 226 patients. Study outcomes included delayed gastric emptying (DGE), nutrition by oral intake, length of hospital stay and survival time. The pooled effects were estimated using a fixed effect model or random effect model based on the heterogeneity test. Results were expressed as odds ratio (OR) and 95% confidence interval (CI) for dichotomous outcomes. For continuous outcomes, the mean of the measures of central tendency was calculated. RESULTS: The GPGJ group had lower rates of DGE (OR =4.997, 95% CI: 2.310-10.810) and length of hospital stay (19.7 versus 23.3 days) and higher rates of nutrition by oral intake (OR =0.156, 95% CI: 0.055-0.442) and survival time (189.2 versus 115.2 days). CONCLUSIONS: GPGJ is associated with lower rates of DGE and higher rates of normal oral intake compared to CGJ with a tendency towards better survival in the GPGJ group. Multicenter randomized controlled trials would be required to confirm these results.
RESUMO
BACKGROUND: Collagen proportionate area (CPA) measurement is a technique that quantifies fibrous tissue in liver biopsies by measuring the amount of collagen deposition as a proportion of the total biopsy area. CPA predicts clinical outcomes in patients with HCV and can sub-classify cirrhosis. AIM: To test the ability of CPA to quantify fibrosis and predict clinical outcomes in patients with NAFLD. METHODS: We assessed consecutive patients with biopsy-proven NAFLD from three European centres. Clinical and laboratory data were collected at baseline and at the time of the last clinical follow-up or death. CPA was performed at two different objective magnifications, whole biopsy macro and ×4 objective magnification, named standard (SM) and high (HM) magnification respectively. The correlation between CPA and liver stiffness was assessed in a sub-group of patients. RESULTS: Of 437 patients, 32 (7.3%) decompensated and/or died from liver-related causes during a median follow-up of 103 months. CPA correlated with liver stiffness and liver fibrosis stage across the whole spectrum of fibrosis. HM CPA was significantly higher than SM CPA in stages F0-F3 but similar in cirrhosis, reflecting a higher ability to capture pericellular/perisinusoidal fibrosis at early stages. Age at baseline (HR: 1.04, 95% CI: 1.01-1.08), HM CPA (HR: 1.04 per 1% increase, 95% CI: 1.01-1.08) and presence of advanced fibrosis (HR: 15.4, 95% CI: 5.02-47.84) were independent predictors of liver-related clinical outcomes at standard and competing risk multivariate Cox-regression analysis. CONCLUSIONS: CPA accurately measures fibrosis and is an independent predictor of clinical outcomes in NAFLD; hence it merits further evaluation as a surrogate endpoint in clinical trials.

Anaemia is a common pathologic condition, present in almost 5% of the adult population. Iron deficiency is the most common cause; other mechanisms can be involved, making anaemia a multi-factorial disorder in most cases. Anaemia being a frequent manifestation in the diseases of the gastrointestinal tract, patients are often referred to gastroenterologists. Furthermore, upper and lower endoscopy and enteroscopy are pivotal to the diagnostic roadmap of anaemia. In spite of its relevance in the daily clinical practice, there is a limited number of gastroenterological guidelines dedicated to the diagnosis of anaemia. For this reason, the Italian Association of Hospital Gastroenterologists and Endoscopists and the Italian Society of Paediatric Gastroenterology, Hepatology and Nutrition commissioned a panel of experts to prepare a specific guideline on anaemia and its diagnostic roadmap in the gastroenterological scenario. The panel also discussed about the potential involvement of gastroenterologists and endoscopists in the management of patients with anaemia, with particular attention to the correct use of investigations. The panel paid particular attention to practical issues with the aim to support gastroenterologists in their clinical practice when dealing with patients with anaemia.

Modern medicine provides almost infinite diagnostic and therapeutic possibilities if compared to the past. As a result, patients undergo a multiplication of tests and therapies, which in turn may trigger further tests, often based on physicians' attitudes or beliefs, which are not always evidence-based. The Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO) adhered to the Choosing Wisely Campaign to promote an informed, evidence-based approach to gastroenterological problems. The aim of this article is to report the five recommendations of the AIGO Choosing Wisely Campaign, and the process used to develop them. The AIGO members' suggestions regarding inappropriate practices/interventions were collected. One hundred and twenty-one items were identified. Among these, five items were selected and five recommendations were developed. The five recommendations developed were: (1) Do not request a fecal occult blood test outside the colorectal cancer screening programme; (2) Do not repeat surveillance colonoscopy for polyps, after a quality colonoscopy, before the interval suggested by the gastroenterologist on the colonoscopy report, or based on the polyp histology report; (3) Do not repeat esophagogastroduodenoscopy in patients with reflux symptoms, with or without hiatal hernia, in the absence of different symptoms or alarm symptoms; (4) Do not repeat abdominal ultrasound in asymptomatic patients with small hepatic haemangiomas (diameter < 3 cm) once the diagnosis has been established conclusively; (5) Do not routinely prescribe proton pump inhibitors within the context of steroid use or long-term in patients with functional dyspepsia. AIGO adhered to the Choosing Wisely Campaign and developed five recommendations. Further studies are needed to assess the impact of these recommendations in clinical practice with regards to clinical outcome and cost-effectiveness.

BACKGROUND: Irritable bowel syndrome (IBS) is the most frequent functional gastrointestinal disorder, both in primary and secondary care. AIMS: (1) To describe diagnostic tools and treatments suggested to IBS patients by Italian gastroenterologists; (2) To evaluate patients' quality of life and psychological involvement and the relationship of these factors with symptom severity. METHODS: Twenty-six gastroenterologists recorded the demographic and clinical data of 677 IBS patients. Diagnostic and treatment measures taken in the previous year and those suggested by gastroenterologists were analysed. RESULTS: IBS with constipation was found in 43.4%, with diarrhoea in 21.6%, mixed-IBS in 35.0%. Routine blood tests, ultrasonography, colonoscopy, barium enema and CT were more frequently requested in the previous year than by the gastroenterologists (pâ¯<â¯0.001). Colonoscopy (11%), and ultrasonography (20.4%) were also suggested by the gastroenterologists in a non-negligible number of patients. Abdominal pain and distension, bowel dissatisfaction, anxiety and depression were more severe in females than in males. Quality of life decreased with increasing IBS-symptom severity. CONCLUSIONS: IBS diagnosis is still largely based on exclusion criteria even if gastroenterologists try to improve diagnostic appropriateness. However, therapy remains symptom-based also in the gastroenterological setting even if gastroenterologists use a wide variety of approaches, including innovative therapies such as linaclotide and psychotherapy.

BACKGROUND AND AIM: Endoscopic ultrasonography (EUS) with or without fine needle aspiration/biopsy (FNA/B) is a well-established diagnostic tool in adults for the evaluation and management of gastrointestinal (GI) tract disorders. Its use in children is still limited as well as literature in pediatric age is limited, although the application of EUS is now increasing. The present article aims to review the current literature about EUS indication, accuracy and safety in pediatric age. METHODS: Electronic literature searches were conducted using Pubmed, Medline, Embase, and the Cochrane Central Register of Controlled Trials using the word pediatric endoscopic ultrasound, pediatric pancreaticobiliary AND/OR EUS, pediatric EUS technique. Main patients and procedures characteristics were analyzed. The primary endpoint was the indication of EUS. Secondary endpoints were the accuracy of the technique and the incidence of complications. RESULTS: Data were extracted from 19 articles. A total of 571 patients were investigated, with a median age of 12,7 years. A total of 634 EUS procedures were performed. The majority of EUS procedures investigated the pancreaticobiliary tract (77,7%). Most studies showed a high positive impact on management with a median value of 81,7%. No major complications were reported. Five studies reported minor complications with a median value of 2%. CONCLUSIONS: EUS is safe and has a significant role in the diagnosis of pancreaticobiliary and GI diseases even in children, with a high therapeutic success. An increasing EUS utilization by pediatric gastroenterologists is expected and offering dedicated EUS training to some selected pediatric gastroenterologists might be indicated.

BACKGROUND: The small bowel has often been considered the mysterious "black hole" of the gastrointestinal tract. With regards to this, the development of the wireless capsule endoscopy (WCE) has represented a turning point. It is a non-invasive technique, enabling an excellent visualization of the small bowel (SB) mucosa without the use of radiation. The WCE was approved by the Food and Drug Administration (FDA) in 2001 for adults and in 2004 for children. The aim of the present review is to provide an update on indications, diagnostic yield, safety and limitations of WCE in children. Even though literature regarding the use of WCE in pediatric age is more limited than in adults, WCE is a useful and safe diagnostic tool for the exploration of the small bowel also in children. The indications for WCE are similar at any age, however the main indication in children is Crohn's disease (CD), while in the adults is the research of SB bleeding. The main limitation in pediatric age is the possibility for younger children to swallow the capsule. WCE in pediatric is a rapidly advancing technology and has the potential to further transform the evaluation and management of SB disease.

BACKGROUND AND AIM OF THE WORK: Historical studies have demonstrated that the prevalence of symptomatic nephrolithiasis is higher in patients with inflammatory bowel disease (IBD), compared to general population. The aim of the review was to analyze literature data in order to identify the main risk conditions described in literature and the proposed treatment. METHODS: A research on the databases PubMed, Medline, Embase and Google Scholar was performed by using the keywords "renal calculi/lithiasis/stones" and "inflammatory bowel diseases". A research on textbooks of reference for Pediatric Nephrology was also performed, with focus on secondary forms of nephrolithiasis. RESULTS: Historical studies have demonstrated that the prevalence of symptomatic nephrolithiasis is higher in patients with inflammatory bowel disease (IBD), compared to general population, typically in patients who underwent extensive small bowel resection or in those with persistent severe small bowel inflammation. In IBD, kidney stones may arise from chronic inflammation, changes in intestinal absorption due to inflammation, surgery or intestinal malabsorption. Kidney stones are more closely associated with Crohn's Disease (CD) than Ulcerative Colitis (UC) in adult patients for multiple reasons: mainly for malabsorption, but in UC intestinal resection may be an additional risk. Nephrolithiasis is often under-diagnosed and might be a rare but noticeable extra-intestinal presentation of pediatric IBD. Secondary enteric hyperoxaluria the main risk factor of UL in IBD, this has been mainly studied in CD, whether in UC has not been completely explained. In the long course of CD recurrent urolithiasis and calcium-oxalate deposition may cause severe chronic interstitial nephritis and, as a consequence, chronic kidney disease. ESRD and systemic oxalosis often develop early, especially in those patients with multiple bowel resections. Even if we consider that many additional factors are present in IBD as hypomagnesuria, acidosis, hypocitraturia, and others, the secondary hyperoxaluria seems to finally have a central role. Some medications as parenteral vitamin D, long-term and high dose steroid treatment, sulfasalazine are reported as additional risk factors. Hydration status may also play an important role in this process. Intestinal surgery is a widely described independent risk factor. Patients with ileostomy post bowel resection may have relative dehydration from liquid stool, which, added to the acidic pH from bicarbonate loss, is responsible for this process. In this acidic pH, the urinary citrate level excretion reduces. The stones most commonly seen in these patients contain uric acid or are mixed. In addition, the risk of calcium containing stones also increases with ileostomy. The treatment of UL in IBD involves correction of the basic gastrointestinal tract inflammation, restricted dietary oxalate intake, and, at times, increased calcium intake. Citrate therapy that increases both urine pH and urinary citrate could also provide an additional therapeutic benefit. Finally, patients with IBD in a pediatric study had less urologic intervention for their calculosis compared with pediatric patients without IBD.

BACKGROUND: Adherence to a healthy diet has been reported to be essential for the primary prevention of colorectal cancer, through a reduction of tissue inflammation, a low concentration of circulating lipoproteins and lower levels of serum cholesterol. Since an altered expression of the fatty acids pattern has been demonstrated to be a crucial event in colorectal carcinogenesis, lipidomic analysis is considered able to identify early diagnostic and prognostic biomarkers of complex diseases such as colorectal cancer. METHODS: cell membrane fatty acid profile and serum lipoproteins pattern were evaluated by gas chromatography and electrophoresis method respectively. RESULTS: There is a close association between diet and lipidomic profile in colorectal cancer, both in pre-clinical and clinical studies. A modified serum lipoproteins pattern has been demonstrated to be predominant in intestinal tumors. CONCLUSIONS: The study of fatty acids profile in cell membrane and the evaluation of serum lipoproteins subfractions could be useful to have an integrate vision on the interactions between lipids and the pathogenesis of colorectal cancer and to understand the mechanisms of action and the consequences of these interactions on human health status.
