Abstract
Introduction Background: little information is availaible on the effect of fructose on bile lipids. The first stage in the formation of gallstones corresponds to biliary cholesterol crystallization, derived from the vesicular transporters. The aim of this study was to investigate the influence of consuming diets with different fructose concentrations on serum lipids and their implications on gallstones formation. Methods: BALB/c mice divided into a control group as well as groups were treated with different fructose concentrations (10 %, 30 %, 50 % or 70 %) for different periods (1, 2 or 5 months). Blood, liver and bile samples were obtained. In bile samples, cholesterol and phospholipids levels were analyzed, and cholesterol transporters (vesicles and micelles) were separated by gel filtration chromatography. Results: treated animals showed: 1) increases in body weight similar to the control group; 2) a significant increase in plasma triglycerides only at very high fructose concentrations; 3) a significant increase in total serum cholesterol in the treatment for 1 month; 4) no variations in HDL-cholesterol; 5) a significant increase in serum glucose only at very high fructose concentrations in the second month of treatment; 6) no differences in the plasma alanine-aminotransferase activity; 7) a significant increase in liver triglyceride levels only at very high fructose concentrations; 8) no change in biliary lipid concentrations or in micellar and vesicular phospholipids. Conclusion: changes in plasma, liver and bile lipids were only observed at very high fructose concentrations diets. We conclude that fructose apparently does not alter the gallstone formation process in our experimental model.

Abstract
BACKGROUND The prevalence of gallstones varies between less than 1% and 64% in different populations and is thought to be increasing in response to changes in nutritional intake and increasing obesity. Some people with gallstones have no symptoms but approximately 2% to 4% develop them each year, predominantly including severe abdominal pain. People who experience symptoms have a greater risk of developing complications. The main treatment for symptomatic gallstones is cholecystectomy. Traditionally, a low-fat diet has also been advised to manage gallstone symptoms, but there is uncertainty over the evidence to support this. OBJECTIVES To evaluate the benefits and harms of modified dietary fat intake in the treatment of gallstone disease in people of any age. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials in the Cochrane Library, MEDLINE ALL Ovid, Embase Ovid, and three other databases to 17 February 2023 to identify randomised clinical trials in people with gallstones. We also searched online trial registries and pharmaceutical company sources, for ongoing or unpublished trials to March 2023. SELECTION CRITERIA We included randomised clinical trials (irrespective of language, blinding, or status) in people with gallstones diagnosed using ultrasonography or conclusive imaging methods. We excluded participants diagnosed with another condition that may compromise dietary fat tolerance. We excluded trials where data from participants with gallstones were not reported separately from data from participants who did not have gallstones. We included trials that investigated other interventions (e.g. trials of drugs or other dietary (non-fat) components) providing that the trial groups had received the same proportion of drug or other dietary (non-fat) components in the intervention. DATA COLLECTION AND ANALYSIS We intended to undertake meta-analysis and present the findings according to Cochrane recommendations. However, as we identified only five trials, with data unsuitable and insufficient for analyses, we described the data narratively. MAIN RESULTS We included five trials but only one randomised clinical trial (69 adults), published in 1986, reported outcomes of interest to the review. The trial had four dietary intervention groups, three of which were relevant to this review. We assessed the trial at high risk of bias. The dietary fat modifications included a modified cholesterol intake and medium-chain triglyceride supplementation. The control treatment was a standard diet. The trial did not report on any of the primary outcomes in this review (i.e. all-cause mortality, serious adverse events, and health-related quality of life). The trial reported on gallstone dissolution, one of our secondary outcomes. We were unable to apply the GRADE approach to determine certainty of evidence because the included trial did not provide data that could be used to generate an estimate of the effect on this or any other outcome. The trial expressed its finding as "no significant effect of a low-cholesterol diet in the presence of ursodeoxycholic acid on gallstone dissolution." There were no serious adverse events reported. The included trial reported that they received no funding that could bias the trial results through conflicts of interest. We found no ongoing trials. AUTHORS' CONCLUSIONS The evidence about the effects of modifying dietary fat on gallstone disease versus standard diet is scant. We lack results from high-quality randomised clinical trials which investigate the effects of modification of dietary fat and other nutrient intakes with adequate follow-up. There is a need for well-designed trials that should include important clinical outcomes such as mortality, quality of life, impact on dissolution of gallstones, hospital admissions, surgical intervention, and adverse events.

Abstract
The Japanese Society of Gastroenterology first published evidence-based clinical practice guidelines for cholelithiasis in 2010, followed by a revision in 2016. Currently, the revised third edition was published to reflect recent evidence on the diagnosis, treatment, and prognosis of cholelithiasis conforming to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Following this revision, the present English version of the guidelines was updated and published herein. The clinical questions (CQ) in the previous version were reviewed and rearranged into three newly divided categories: background questions (BQ) dealing with basic background knowledge, CQ, and future research questions (FRQ), which refer to issues that require further accumulation of evidence. Finally, 52 questions (29 BQs, 19 CQs, and 4 FRQs) were adopted to cover the epidemiology, pathogenesis, diagnosis, treatment, complications, and prognosis. Based on a literature search using MEDLINE, Cochrane Library, and Igaku Chuo Zasshi databases for the period between 1983 and August 2019, along with a manual search of new information reported over the past 5 years, the level of evidence was evaluated for each CQ. The strengths of recommendations were determined using the Delphi method by the committee members considering the body of evidence, including benefits and harms, patient preference, and cost-benefit balance. A comprehensive flowchart was prepared for the diagnosis and treatment of gallbladder stones, common bile duct stones, and intrahepatic stones, respectively. The current revised guidelines are expected to be of great assistance to gastroenterologists and general physicians in making decisions on contemporary clinical management for cholelithiasis patients.

Abstract
Dietary factors are believed to potentially influence the risk of pancreatitis. Here, we systematically investigated the causal relationships between dietary habits and pancreatitis by using two-sample Mendelian randomization (MR). Large-scale genome-wide association study (GWAS) summary statistics for dietary habits were obtained from the UK Biobank. GWAS data for acute pancreatitis (AP), chronic pancreatitis (CP), alcohol-induced AP (AAP) and alcohol-induced CP (ACP) were from the FinnGen consortium. We performed univariable and multivariable MR analyses to evaluate the causal association between dietary habits and pancreatitis. Genetically driven alcohol drinking was associated with increased odds of AP, CP, AAP and ACP (all with p < 0.05). Genetic predisposition to higher dried fruit intake was associated with reduced risk of AP (OR = 0.280, p = 1.909 × 10-5) and CP (OR = 0.361, p = 0.009), while genetic predisposition to fresh fruit intake was associated with reduced risk of AP (OR = 0.448, p = 0.034) and ACP (OR = 0.262, p = 0.045). Genetically predicted higher consumption of pork (OR = 5.618, p = 0.022) or processed meat (OR = 2.771, p = 0.007) had a significant causal association with AP, and genetically predicted higher processed meat intake increased the risk of CP (OR = 2.463, p = 0.043). Our MR study showed that fruit intake may be protective against pancreatitis, whereas dietary intake of processed meat has potential adverse impacts. These findings may inform prevention strategies and interventions directed toward dietary habits and pancreatitis.

Abstract
Cholelithiasis is a common and frequent condition all over the world with a high prevalence rate in western countries. Individuals with cholesterol gallstone disease experience intense gastrointestinal symptoms and have a high risk of developing comorbidities like cholecystitis, Gall bladder (GB) cancer and pancreatitis. Multiple risk factors associated with cholesterol gallstones include but not limited to genetics, dietary habits, lifestyle changes, comorbid conditions and various drugs. These factors may lead to alteration in bile, cholesterol & phospholipids homeostasis in the GB, intestine and hepatocytes culminating in cholesterol gallstones formation. Surgical (cholecystectomy) and non-surgical (oral dissolution therapy) treatments are available for the disease, albeit with certain complications and high treatment cost. Thus, there is a need for interventions, complementary or alternative therapies for the treatment and prevention of cholesterol gallstones. Currently available drug therapies used for cholesterol gallstones include statins and ezetimibe. Many patients consider traditional herbal practitioners due to their promise of non-invasive and pain free management of gall stones. This present a positive shift towards generally acceptable safety and cost effectiveness of herbal treatment warranting extensive research for alternative or complementary choice such as herbal plants as an emerging area for their potential therapeutic effects. This review discusses current strategies, latest trends available in the disease pathogenesis, drug development for novel targets, risk management, newer anti-lithogenic drugs and herbal plants that target the different aspects of the disease.

Abstract
The increasing prevalence of cholesterol gallstone disease places an economic burden on the healthcare system. To identify novel therapeutics, we assessed the effects of n-3 polyunsaturated fatty acids (PUFA) in combination with UDCA in a mouse model of cholesterol gallstones. Gallstone dissolution, gallbladder wall thickness, mucin gene expression in the gallbladder, and levels of phospholipids, cholesterol, and bile acids in bile and serum were analysed. RNA was extracted from the liver for mRNA sequencing and gene expression profiling. Combination treatment resulted in greater gallstone dissolution compared with the control group, and PUFA and combination treatments reduced the thickness of the gallbladder wall. Expression levels of mucin genes were significantly lower in the UDCA, PUFA, and combination groups. Transcriptome analyses revealed that combination treatment modulated hepatic lipid metabolism. The PUFA and combination groups showed elevated bile phospholipid and bile acid levels and a lower cholesterol saturation index. Combination treatment with PUFA and UDCA dissolves cholesterol gallstones in mice by decreasing mucin production, increasing levels of phospholipids and bile acids in bile, and decreasing cholesterol saturation. Further studies of the therapeutic effects of combination PUFA and UDCA treatment in patients with cholesterol gallstones are warranted.

Abstract
Cholesterol gallstone disease is a major health problem in Westernized countries and depends on a complex interplay between genetic factors, lifestyle and diet, acting on specific pathogenic mechanisms. Overweigh, obesity, dyslipidemia, insulin resistance and altered cholesterol homeostasis have been linked to increased gallstone occurrence, and several studies point to a number of specific nutrients as risk- or protective factors with respect to gallstone formation in humans. There is a rising interest in the identification of common and modifiable dietetic factors that put the patients at risk of gallstones or that are able to prevent gallstone formation and growth. In particular, dietary models characterized by increased energy intake with highly refined sugars and sweet foods, high fructose intake, low fiber contents, high fat, consumption of fast food and low vitamin C intake increase the risk of gallstone formation. On the other hand, high intake of monounsaturated fats and fiber, olive oil and fish (ω-3 fatty acids) consumption, vegetable protein intake, fruit, coffee, moderate alcohol consumption and vitamin C supplementation exert a protective role. The effect of some confounding factors (e.g., physical activity) cannot be ruled out, but general recommendations about the multiple beneficial effects of diet on cholesterol gallstones must be kept in mind, in particular in groups at high risk of gallstone formation.

[PMID: 30310412 PMCID: PMC6166389 DOI: 10.1155/2018/8134918] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/09/2018] [Revised: 05/28/2018] [Accepted: 07/22/2018] [Indexed: 12/16/2022]
Abstract
The study attempted to elucidate whether lipid genes are closely associated with lipid metabolic abnormalities during the lithogenic time and how Yinchenhao Decoction (YCHD) works on the transcriptions of lipid genes against cholesterol gallstone model. C57BL/6J mice fed on lithogenic diet (LD) were used for model establishment and randomized into 5 groups. All groups received LD for different weeks with isometrically intragastric administration of YCHD or NS. Biochemical tests were measured and liver tissues were harvested for histological and genetic detection. It was found that all groups with increasing LD showed a following tendency of gallstone incidence, bile cholesterol, phospholipids, total bile acid, and cholesterol saturation index (CSI). Conversely, YCHD could significantly normalize the levels of gallstone incidence, bile lipids, and CSI (CSI<1). As lithogenic time progressed, ABCG5, ABCG8, PPAR-α, and ABCB4 were upregulated, and SREBP2, CYP7A1, and CYP7B1 were downregulated, while CYP7A1, CYP7B1, LXR, and HMGCR mRNA were increased 3-fold under the administration of YCHD. It was concluded that abnormal expressions of the mentioned genes may eventually progress to cholesterol gallstone. CYP7A1, CYP7B1, LXR, and HMGCR mRNA may be efficient targets of YCHD, which may be a preventive drug to reverse liver injury, normalize bile lipids, facilitate gallstone dissolution, and attenuate gallstone formation.

Abstract
BACKGROUND Gallstone disease (GD) belongs to the most frequent disorders in gastroenterology and causes high costs in our health-care systems. Gallstones are uncommon in children but frequent in adults, in particular in women, and are triggered by exogenous risk factors. Here, we summarize the current knowledge concerning the contribution of inherited predisposition to gallstone risk. DESIGN In this review, we present the current data and recent research on the genetics of gallstone disease. RESULTS Several GD-predisposing gene variants have been reported, with most prominent effects being conferred by a common variant (p.D19H) of the hepatic and intestinal cholesterol transporter ABCG5/G8. A smaller group of patients might develop gallstones primarily due low phosphatidylcholine concentrations in bile as a result of loss-of-function mutations of the ABCB4 transporter (low phospholipid-associated cholelithiasis syndrome). Regardless of the origin, the risk factors for gallstones lead to the supersaturation of bile with insoluble compounds, in particular cholesterol. As result, cholesterol stones develop and present the most frequent type of gallstones. Laparoscopic cholecystectomy with low morbidity and mortality is currently the most common and effective method for the therapy of symptomatic gallbladder stones. CONCLUSIONS Gallstone disease represents a multifactorial condition and previous studies have identified the major genetic contributors to gallstone formation. The increasing knowledge about the pathomechanisms of hepatobiliary metabolism and GD as well as the identification of additional risk factors might help to overcome the current invasive therapy by specific lifestyle intervention and precise molecular treatment.

Abstract
BACKGROUND Gallbladder disease (GBD) is a highly prevalent condition; however, little is known about potential differences in risk factors by sex and ethnicity/race. Our aim was to evaluate dietary, reproductive and obesity-related factors and GBD in multiethnic populations. METHODS We performed a prospective analysis from the Multiethnic Cohort study who self-identified as non-Hispanic White (n = 32,103), African American (n = 30,209), Japanese (n = 35,987), Native Hawaiian (n = 6942) and Latino (n = 39,168). GBD cases were identified using Medicare and California hospital discharge files (1993-2012) and self-completed questionnaires. We used exposure information on the baseline questionnaire to identify exposures of interest. Associations were estimated by hazard ratios and 95% confidence intervals using Cox models adjusted for confounders. RESULT After a median 10.7 years of follow-up, there were 13,437 GBD cases. BMI over 25 kg/m2, diabetes, past and current smoking, red meat consumption, saturated fat and cholesterol were significant risk factors across ethnic/racial populations (p-trends < 0.01). Protective factors included vigorous physical activity, alcohol use, fruits, vegetables and foods rich in dietary fiber (p-trends < 0.01). Carbohydrates were inversely associated with GBD risk only among women and Latinos born in South America/Mexico (p-trend < 0.003). Parity was a significant risk factor among women; post-menopausal hormones use was only associated with an increased risk among White women (estrogen-only: HR = 1.24; 95% CI = 1.07-1.43 and estrogen + progesterone: HR = 1.23; 95% CI = 1.06-1.42). CONCLUSION Overall, dietary, reproductive and obesity-related factors are strong risk factors for GBD affecting men and women of different ethnicities/races; however some risk factors appear stronger in women and certain ethnic groups.

Abstract
OBJECTIVES This study aimed to examine the relationship between diet and cholecystectomy risk, using three approaches, in a large French cohort. METHODS In a prospective cohort study in French women who completed a food-frequency questionnaire at baseline, we analyzed diet with three approaches: food groups, dietary patterns obtained by factor analysis, and the Mediterranean diet score. The primary outcome was cholecystectomy. We used Cox proportional hazards regression to assess the relationship between diet and cholecystectomy risk, adjusting for the main potential confounders. RESULTS During 1,033,955 person years of follow-up, we identified 2,778 incident cases of cholecystectomy. Higher intakes of legumes, fruit, vegetable oil, and wholemeal bread were associated with decreased cholecystectomy risk. Two dietary patterns were identified by factor analysis: "Western" (essentially processed meat, pizza, pies, high-alcohol beverages, French fries, sandwiches…) and "Mediterranean" (essentially fruits, vegetables, seafood, and olive oil). The "Mediterranean" pattern was inversely associated with cholecystectomy risk in the subgroup of postmenopausal women who ever used menopausal hormone therapy (hazard ratio for quartile 4 vs. 1=0.79, 95% confidence interval (CI): 0.65-0.95; P for linear trend=0.008). High adherence to the Mediterranean diet was associated with decreased risk of cholecystectomy (hazard ratio for a 6-9 score vs. 0-3=0.89, 95% CI: 0.80-0.99; P for linear trend=0.02). CONCLUSIONS Adherence to a diet rich in fruit, vegetables, legumes, and olive oil was associated with a reduction in cholecystectomy risk in French women. Further studies in different settings are requested.

Abstract
BACKGROUND & AIMS Pancreatitis is a source of substantial morbidity and health cost in the United States. Little is known about how diet might contribute to its pathogenesis. To characterize dietary factors that are associated with risk of pancreatitis by disease subtype, we conducted a prospective analysis of 145,886 African Americans, Native Hawaiians, Japanese Americans, Latinos, and whites in the Multiethnic Cohort. METHODS In the Multiethnic Cohort (age at baseline, 45-75 y), we identified cases of pancreatitis using hospitalization claim files from 1993 through 2012. Patients were categorized as having gallstone-related acute pancreatitis (AP) (n = 1210), AP not related to gallstones (n = 1222), or recurrent AP or suspected chronic pancreatitis (n = 378). Diet information was obtained from a questionnaire administered when the study began. Associations were estimated by hazard ratios and 95% confidence intervals using Cox proportional hazard models adjusted for confounders. RESULTS Dietary intakes of saturated fat (P trend = .0011) and cholesterol (P trend = .0008) and their food sources, including red meat (P trend < .0001) and eggs (P trend = .0052), were associated positively with gallstone-related AP. Fiber intake, however, was associated inversely with gallstone-related AP (P trend = .0005) and AP not related to gallstones (P trend = .0035). Vitamin D, mainly from milk, was associated inversely with gallstone-related AP (P trend = .0015), whereas coffee consumption protected against AP not related to gallstones (P trend < .0001). With the exception of red meat, no other dietary factors were associated with recurrent acute or suspected chronic pancreatitis. CONCLUSIONS Associations between dietary factors and pancreatitis were observed mainly for gallstone-related AP. Interestingly, dietary fiber protected against AP related and unrelated to gallstones. Coffee drinking protected against AP not associated with gallstones. Further studies are warranted to confirm our findings.

Abstract
This study explores the environmental impact of metal exposure on humans through detailed phase and structural characterization of gallstones from two environmentally contrasting populations in Huelva Province (SW Spain). A total of 42 gallstone samples, obtained after surgical intervention at the Riotinto Hospital, were studied by powder X-ray diffraction (XRD), Fourier Transformed Infra-Red spectroscopy (FTIR), FTIR-μ-ATR (Attenuated Total Reflection) coupled with an optical microscope, and by Environmental Scanning Electron Microscope with Energy Dispersive X-ray Spectroscopy (ESEM-EDS), and subsequently classified according to their phase composition and structure. Additionally, the patients were enquired for their living habits in order to analyze the source of possible exposure to metal contamination. The gallstones were classified into pure, mixed and composite cholesterol stones, black and brown pigment stones, and carbonate stones. The patients from the study group residing in a region with acknowledged metal contamination of both natural and anthropogenic origin have a higher risk of metal exposure through contaminated soil, particle matter in the air, and consumption of local water and food products. According to our findings, the metal exposure is related to a higher tendency of forming black pigment stones in the study group in comparison to the control group residing in a natural park with nearly pristine environmental conditions. Moreover, the gallstones from the study group showed to contain more abundant metal components, such as Cu, Fe, Ni, and Zn, than those from the control group. To our knowledge this is the first study to examine the regional environmental impact of metal exposure on human gallstones.

Abstract
It has been reported that intake of ω-3 polyunsaturated fatty acids (PUFAs) reduces the risk of coronary heart disease. It also influences bile composition, decreasing biliary cholesterol saturation in the bile of patients with gallstones. In addition to bile composition disturbances, gallbladder hypomotility must be a cofactor in the pathogenesis of cholelithiasis, as it leads to the prolonged nucleation phase. Our current knowledge about gallbladder motility has been enhanced by the study of a population of newly described interstitial (stromal) cells-telocytes (TCs). The purpose of this study was to determine whether TC loss, reported by our team recently, might be related to bile lithogenicity, expressed as cholesterol saturation index or the difference in biliary PUFA profiles in patients who suffer from cholecystolithiasis and those not affected by this disease. We determined biliary lipid composition including the fatty acid composition of the phospholipid species in bile. Thus, we investigated whether differences in biliary fatty acid profiles (ω-3 PUFA and ω-6 PUFA) in gallbladder bile may influence its lithogenicity and the quantity of TCs within the gallbladder wall. We conclude that the altered PUFA concentrations in the gallbladder bile, with elevation of ω-6 PUFA, constitute important factors influencing TC density in the gallbladder wall, being one of the possible pathophysiological components for the gallstone disease development. This study established that altered bile composition in patients with cholelithiasis may influence TC quantity within the gallbladder muscle, and we concluded that reduction in TC number may be a consequence of the supersaturated bile toxicity, while some other bile components (ω-3 PUFA, glycocholic, and taurocholic acids) may exert protective effects on TC and thus possibly influence the mechanisms regulating gallbladder and extrahepatic bile duct motility. Thus, ω-3 PUFA may represent a possible option to prevent formation of cholesterol gallstones.

Abstract
The aim of the study was to examine the mechanism of action of Lidan Granule (LDG) for the prevention of gallstones using a guinea pig model. One hundred guinea pigs were divided into five groups randomly: control (standard diet and saline), model [lithogenic diet (LD) and saline], LDG-H (LD and 2 g/kg of LDG), LDG-L (LD and 1 g/kg of LDG), and ursodeoxycholic acid (UDCA) (LD and UDCA) as the positive control. At 6 weeks, the rate of gallstone formation and weight of the adrenal gland were recorded and serum levels of inflammatory cytokines were measured. Levels of corticotrophin-releasing hormone (CRH) in the hypothalamus, adrenocorticotropic hormone (ACTH) in the hypophysis, and serum cortisol were determined. Bile components were tested with colorimetry. At 6 weeks, the rate of gallstone formation was significantly decreased in the LDG-H (14.29%) and LDG-L (21.43%) groups compared to the model group (81.25%; P<0.01). LDG treatment decreased the serum levels of interleukin (IL)-1, IL-6, and tumor necrosis factor-α (P<0.01). LDG decreased bile cholesterol and increased bile acid and phospholipid levels in the bile (P<0.01). LDG treatment recovered the function of the hypothalamic-pituitary-adrenal (HPA) axis by increasing the expression of CRH (P<0.01) and ACTH (P<0.05). LDG made the bile less lithogenic, improved the function of the HPA axis, and regulated the expression of inflammatory cytokines for the prevention of cholelithiasis.

Abstract
AIM There is emerging evidence from animal and human studies that current statins can decrease the formation of gallbladder cholesterol gallstones and subsequently decrease the risk of gallstone disease, but consistent results have not been reported. We performed a meta-analysis to provide an overview of the relevant studies. METHODS Relevant studies published between January 1980 and February 2014 were identified by searching Medline, Embase and the Cochrane Library. Studies were selected using a priori defined criteria. The strength of the relationship between statin use and risk of gallstone disease was assessed by adjusted odds ratio (OR). RESULTS A total of 622 868 participants from six studies (four case-control studies, one cohort study and one cross-sectional study) were identified in this meta-analysis. The studies provided adjusted overall OR estimates for current statin use versus non-use, leading to a pooled OR of 0.86 (95% confidence interval [CI], 0.77-0.97; P < 0.001). The overall OR of population-based case-control studies and cholecystectomy due to gallstone disease were 0.83 (95% CI, 0.73-0.95; P = 0.0131) and 0.78 (95% CI, 0.74-0.82; P = 0.615), respectively. CONCLUSION There is evidence that current statin use lowers the risk of gallstone disease compared with non-use, especially for cholecystectomy due to gallstone disease. Low statin use (1-4 prescriptions) did not decrease the risk of gallstone disease, but moderate and high statin use significantly decreased the risk. Further multicenter and better controlled studies are needed to confirm these findings.

Abstract
BACKGROUND Gallstone disease (GD) incidence and prevalence rates differ between populations. Diet and lifestyle may be involved in GD development. To our knowledge, no study to date has evaluated quantitative data on diet when studying the relationship between fat consumption levels and GD in an Argentinean population. The present study aimed to assess the association between dietary fat intake and GD. METHODS A nested case-control study design was applied. Data were taken from subjects who participated in a previous cross-sectional study carried out in a random sample of asymptomatic people in Rosario, Argentina. Participants underwent a personal interview, and current weight and height, ancestor's ethnicity, and socio-economic status were recorded. Applying a food-frequency questionnaire and a food photography atlas, quantitative dietary data were estimated by combining the intake frequency, portion size and food composition. Logistic regression analysis was used to compute odds ratios and 95% confidence intervals adjusted by age, sex, ancestor's ethnicity, body mass index and daily total energy intake as potential confounders. RESULTS In total, 114 patients were studied (49 cases and 65 controls), without any statistically significant differences for age, sex, socio-economic status, body mass index and ancestry. The mean energy intake was higher in cases than in controls, and significant differences were found for dietary fat consumption. Obese or overweight people have a higher GD risk than subjects with normal weight. Increased GD risks were associated with high intakes of energy, total fat, and saturated and monounsaturated fatty acids. CONCLUSIONS According to our results, total fat, saturated and monounsaturated fatty acids high intakes are associated with increased GD risk.

Abstract
AIM: To investigate the role of caveolin-3 (CAV3) and cholecystokinin A receptor (CCKAR) in cholesterol gallstone disease (CGD).
METHODS: To establish a mouse model of CGD, male C57BL/6 mice were fed with a lithogenic diet containing 1.0% cholic acid, 1.25% cholesterol and 15% fat; a similar control group was given a normal diet. The fresh liver weights and liver-to-body weight ratio were compared between the two groups after one month. Serum lipid profile and bile composition were determined with an autoanalyzer. The Cav3 and Cckar mRNA and CAV3 and CCKAR protein levels in the liver and gallbladder were determined via real-time polymerase chain reaction and Western blot, respectively.
RESULTS: Establishment of the mouse CGD model was verified by the presence of cholesterol gallstones in mice fed the lithogenic diet. Compared with mice maintained on a normal diet, those fed the lithogenic diet had significantly higher mean liver-to-body weight ratio (0.067 ± 0.007 vs 0.039 ± 0.007, P < 0.01), serum total cholesterol (4.22 ± 0.46 mmol/L vs 2.21 ± 0.11 mmol/L, P < 0.001), bile total cholesterol (1.33 ± 0.33 mmol/L vs 0.21 ± 0.11 mmol/L, P < 0.001), and bile phospholipid concentrations (3.55 ± 1.40 mmol/L vs 1.55 ± 0.63 mmol/L, P = 0.04), but lower total bile acid concentrations (726.48 ± 51.83 μmol/L vs 839.83 ± 23.74 μmol/L, P = 0.007). The lithogenic diet was also associated with significantly lower CAV3 in the liver and lower CAV3 and CCKAR in the gallbladder compared with the control mice (all P < 0.05).
CONCLUSION: CAV3 and CCKAR may be involved in cholesterol gallstone disease.

Abstract
A growing body of evidence supports a connection among diabetes (predominantly type 2), obesity, and cancer. Multiple meta-analyses of epidemiological data show that people with diabetes are at increased risk of developing a variety of different cancers and suffer from an increased rate of perioperative complications and cancer mortality. Computed tomography (CT) has played an important role in diagnosis and staging of cancer. Positron emission tomography is complementary to CT in the diagnosis, staging, and evaluation of treatment response for many types of cancer. Because of generally poor clinical outcome of cancers when they are detected in late stages, more research is now focused on stratifying risk to allow personalized screening of at-risk patients and cancer detection at an earlier stage. In this review, we summarize basic noninvasive imaging techniques currently in use to detect cancer with emphasis on the challenges of imaging for early cancer detection in obese patients with diabetes.

Abstract
Gallstone disease represents one of the most common gastroenterological disorders worldwide. Gallstones affect over 15% of adults in Europe and 25-30% of Hispanic populations in Central and South America. The heritability of gallstones varies considerably according to ethnicity, with Native Americans and Hispanics with Amerindian admixture being the most susceptible populations. Genetic factors have been shown to account for 25-30% of total gallstone risk in Europe, however, in Hispanic populations, this risk percentage may increase to 45-65%. Recent genome-wide association and candidate gene studies have identified common polymorphisms in enterohepatic transporters (ABCG5/8, SLC10A2) and the Gilbert syndrome UGT1A1 variant as genetic determinants of gallstone formation. Together, these polymorphisms cover a significant proportion of the previously predicted genetic background of gallstones in European populations. New lithogenic genes need to be discovered in future studies in high-risk populations. In this review, we address the latest developments in the genetic analysis of gallstones and discuss the ethnic background of this condition in European, Central and South American and Asian populations.

Abstract
BACKGROUND AND AIM The increasing prevalence of cholesterol gallstone (CG) disease has become an economic burden to the healthcare system. Ursodeoxycholic acid (UDCA) is the only established medical agent used to dissolve gallstones. In investigating novel therapeutics for CG, we assessed the preventive effects of n-3 polyunsaturated fatty acids (n-3PUFA) on the formation of CG induced by feeding a lithogenic diet (LD) containing high cholesterol levels to mice. METHODS Mice were divided into the following six groups: (A) regular diet (RD); (B) RD+n-3PUFA; (C) LD; (D) LD+n-3PUFA; (E) LD+UDCA; (F) LD+n-3PUFA+UDCA. After RD/LD feeding for 2 weeks, n-3PUFA or UDCA was administered orally and the diet maintained for 8 weeks. The levels of phospholipids and cholesterol in bile, CG formation, gallbladder wall thickness, MUC gene expression in gallbladder were analyzed. RESULTS No stone or sludge was evident in the RD groups (Groups A, B). Mice in the n-3PUFA treatment (Groups D, F) showed significantly lower stone formation than the other LD groups (Groups C, E). The combination treatment of n-3PUFA and UDCA suppressed stone formation more than mono-therapy with n-3PUFA or UDCA. Bile phospholipid levels were significantly elevated in the Group F. Hypertrophy of the gallbladder wall was evident in mice fed LD. MUC 2, 5AC, 5B and 6 mRNA expression levels were significantly elevated in the LD-fed group, and this was suppressed by n-3PUFA with or without UDCA. CONCLUSIONS N-3PUFA attenuated gallstone formation in mouse, through increasing the levels of bile phospholipids and suppressing bile mucin formation.

Abstract
Diseases of the gallbladder are common and costly. The best epidemiological screening method to accurately determine point prevalence of gallstone disease is ultrasonography. Many risk factors for cholesterol gallstone formation are not modifiable such as ethnic background, increasing age, female gender and family history or genetics. Conversely, the modifiable risks for cholesterol gallstones are obesity, rapid weight loss and a sedentary lifestyle. The rising epidemic of obesity and the metabolic syndrome predicts an escalation of cholesterol gallstone frequency. Risk factors for biliary sludge include pregnancy, drugs like ceftiaxone, octreotide and thiazide diuretics, and total parenteral nutrition or fasting. Diseases like cirrhosis, chronic hemolysis and ileal Crohn's disease are risk factors for black pigment stones. Gallstone disease in childhood, once considered rare, has become increasingly recognized with similar risk factors as those in adults, particularly obesity. Gallbladder cancer is uncommon in developed countries. In the U.S., it accounts for only ~ 5,000 cases per year. Elsewhere, high incidence rates occur in North and South American Indians. Other than ethnicity and female gender, additional risk factors for gallbladder cancer include cholelithiasis, advancing age, chronic inflammatory conditions affecting the gallbladder, congenital biliary abnormalities, and diagnostic confusion over gallbladder polyps.

Abstract
Cholesterol gallstones are associated with slow intestinal transit in humans as well as in animal models, but the molecular mechanism is unknown. We investigated in C57L/J mice whether the components of a lithogenic diet (LD; 1.0% cholesterol, 0.5% cholic acid and 17% triglycerides), as well as distal intestinal infection with Helicobacter hepaticus, influence small intestinal transit time. By quantifying the distribution of 3H-sitostanol along the length of the small intestine following intraduodenal instillation,we observed that, in both sexes, the geometric centre (dimensionless) was retarded significantly (P <0.05) by LD but not slowed further by helicobacter infection (males, 9.4±0.5 (uninfected), 9.6±0.5 (infected) on LD compared with 12.5±0.4 and 11.4±0.5 on chow). The effect of the LD was reproduced only by the binary combination of cholesterol and cholic acid. We inferred that the LD-induced cholesterol enrichment of the sarcolemmae of intestinal smooth muscle cells produced hypomotility from signal-transduction decoupling of cholecystokinin (CCK), a physiological agonist for small intestinal propulsion in mice. Treatment with ezetimibe in an amount sufficient to block intestinal cholesterol absorption caused small intestinal transit time to return to normal. In most cholesterol gallstone-prone humans, lithogenic bile carries large quantities of hepatic cholesterol into the upper small intestine continuously, thereby reproducing this dietary effect in mice. Intestinal hypomotility promotes cholelithogenesis by augmenting formation of deoxycholate, a pro-lithogenic secondary bile salt, and increasing the fraction of intestinal cholesterol absorbed.

Abstract
The cholesterol absorption inhibitor ezetimibe can significantly reduce plasma cholesterol concentrations by inhibiting the Niemann-Pick C1-like 1 protein (NPC1L1), an intestinal sterol influx transporter that can actively facilitate the uptake of cholesterol for intestinal absorption. Unexpectedly, ezetimibe treatment also induces a complete resistance to cholesterol gallstone formation and nonalcoholic fatty liver disease (NAFLD) in addition to preventing hypercholesterolemia in mice on a Western diet. Because chylomicrons are the vehicles with which the enterocytes transport cholesterol and fatty acids into the body, ezetimibe could prevent these two most prevalent hepatobiliary diseases possibly through the regulation of chylomicron-derived cholesterol and fatty acid metabolism in the liver. It is highly likely that there is an intestinal and hepatic cross-talk through the chylomicron pathway. Therefore, understanding the molecular mechanisms whereby cholesterol and fatty acids are absorbed from the intestine could offer an efficacious novel approach to the prevention and the treatment of cholesterol gallstones and NAFLD.

Abstract
The protein kinase C (PKC) family of Ca(2+) and/or lipid-activated serine-threonine protein kinases is implicated in the pathogenesis of obesity and insulin resistance. We recently reported that protein kinase Cβ (PKCβ), a calcium-, diacylglycerol-, and phospholipid-dependent kinase, is critical for maintaining whole body triglyceride homeostasis. We now report that PKCβ deficiency has profound effects on murine hepatic cholesterol metabolism, including hypersensitivity to diet-induced gallstone formation. The incidence of gallstones increased from 9% in control mice to 95% in PKCβ(-/-) mice. Gallstone formation in the mutant mice was accompanied by hyposecretion of bile acids with no alteration in fecal bile acid excretion, increased biliary cholesterol saturation and hydrophobicity indices, as well as hepatic p42/44(MAPK) activation, all of which enhance susceptibility to gallstone formation. Lithogenic diet-fed PKCβ(-/-) mice also displayed decreased expression of hepatic cholesterol-7α-hydroxylase (CYP7A1) and sterol 12α-hydroxylase (CYP8b1). Finally, feeding a modified lithogenic diet supplemented with milk fat, instead of cocoa butter, both increased the severity of and shortened the interval for gallstone formation in PKCβ(-/-) mice and was associated with dramatic increases in cholesterol saturation and hydrophobicity indices. Taken together, the findings reveal a hitherto unrecognized role of PKCβ in fine tuning diet-induced cholesterol and bile acid homeostasis, thus identifying PKCβ as a major physiological regulator of both triglyceride and cholesterol homeostasis.

Abstract
Gallstones are common with prevalences as high as 60% to 70% in American Indians and 10% to 15% in white adults of developed countries. Ethnic differences abound with a reduced frequency in black Americans and those from East Asia, while being rare in sub-Saharan Africa. Certain risk factors for gallstones are immutable: female gender, increasing age, and ethnicity/family (genetic traits). Others are modifiable: obesity, the metabolic syndrome, rapid weight loss, certain diseases (cirrhosis and Crohn disease), gallbladder stasis (from spinal cord injury or drugs, such as somatostatin), and lifestyle.

Abstract
The purpose of this study was to examine a previous increase in male gallstone disease and to consider the burden of gallstones in a necropsy study with matched controls over a decade. Gallstone prevalence in 5,050 males fell from 20.2% to 19.1% (P=0.022) and in 4,125 females fell from 30.4% to 29.0% (P=0.03). Female gallstone subjects had a higher BMI than controls 24.5 vs. 23.3 (P<0.01), but males did not. Gallstones were twice as common in diabetics, but not with coronary heart disease (CHD). A third of elderly patients of both sexes had gallstones, but cholecystectomy was more common in females, 17:10%. Gallstone-related mortality was 0.7%. The prevalence of gallstones fell slightly. The association between gallstones and diabetes was confirmed, but not for CHD, and for BMI this was confined to females. Gallstones are very common in the elderly, but most are unoperated and seldom cause death.

Abstract
Gallstone disease is one of the most prevalent gastrointestinal disorders. In addition, the costs associated with the diagnosis and treatment of gallstone disease have been rapidly increasing. The etiology and pathogenesis of gallstone disease remains incompletely understood. Gallstone formation may result from a complex interaction of genetic and environmental factors. This article reviews the prevalence and risk factors associated with gallstone disease. Understanding the pathogenesis of gallstone disease could lead to the development of better therapeutic and preventive strategies for dealing with this disease.

Abstract
BACKGROUND Animal experiments have shown a protective effect of vitamin C on the formation of gallstones. Few data in humans suggest an association between reduced vitamin C intake and increased prevalence of gallstone disease. The aim of this study was to assess the possible association of regular vitamin C supplementation with gallstone prevalence. METHODS An observational, population-based study of 2129 subjects aged 18-65 years randomly selected from the general population in southern Germany was conducted. Abdominal ultrasound examination, completion of a standardized questionnaire, compilation of anthropometric data and blood tests were used. Data were collected in November and December 2002. Data analysis was conducted between December 2005 and January 2006. RESULTS Prevalence of gallstones in the study population was 7.8% (167/2129). Subjects reporting vitamin C supplementation showed a prevalence of 4.7% (11/232), whereas in subjects not reporting regular vitamin C supplementation, the prevalence was 8.2% (156/1897). Female gender, hereditary predisposition, increasing age and body-mass index (BMI) were associated with increased prevalence of gallstones. Logistic regression with backward elimination adjusted for these factors showed reduced gallstone prevalence for vitamin C supplementation (odds ratio, OR 0.34; 95% confidence interval, CI 0.14 to 0.81; P = 0.01), increased physical activity (OR 0.62; 95% CI, 0.42 to 0.94; P = 0.02), and higher total cholesterol (OR 0.65; 95% CI, 0.52 to 0.79; P < 0.001). CONCLUSION Regular vitamin C supplementation and, to a lesser extent, increased physical activity and total cholesterol levels are associated with a reduced prevalence of gallstones. Regular vitamin C supplementation might exert a protective effect on the development of gallstones.

Abstract
OBJECTIVES Gallstones are a common disease worldwide, with disparities in the prevalence of the disease in different settings. The aim of the present study was to assess if different distributions of risk factors could explain the disparities in the prevalence of gallstone disease between Denmark and northeast Germany. METHODS Data of 5,559 subjects from the Danish MONICA survey and of 3,647 subjects of the German Study of Health in Pomerania were investigated. Gallstone disease was defined as a prior history of cholecystectomy or the presence of sonographically diagnosed gallstones. Logistic regression models were performed to assess the confounding effect of selected risk factors on regional disparities in gallstone disease. RESULTS After adjustment for age and vocational training, German subjects (women: Odds ratio, OR, 2.46 (95% confidence interval, CI: 2.07-2.91); men: OR, 1.89 (95% CI: 1.52-2.36)) had approximatively twice the odds of gallstones than Danes. Inclusion of lifestyle factors (smoking, alcohol intake, coffee use) did not affect this result, whereas adjustment for body mass index (BMI), lipids, diabetes, and use of oral contraceptives, menopausal hormone therapy (MHT) and parity (women only) changed the estimates considerable, but still Germans (women: OR, 1.65 (95% CI: 1.36-2.00); men: OR, 1.61 (95% CI: 1.27-2.04)) had higher odds than Danes. CONCLUSIONS German individuals had a higher prevalence of gallstones than Danes. This difference was partly explained by a higher BMI, unfavorable lipid levels, higher prevalence of diabetes, and a more frequent use of OR and MHT in German subjects. Further research is needed to evaluate the impact of unmeasured predictors, including genetic components, on the population-related risk of gallstones.

Abstract
Cholelithiasis is a major source of digestive morbidity worldwide. Cholesterol stones account for the majority of gallstones in the United States and other Western countries. The pathogenesis of cholesterol gallstone disease is multifactorial with key factors including cholesterol supersaturation of bile, altered biliary motility, and nucleation and growth of cholesterol crystals. Increasing evidence suggests that many, but not all, causative factors of cholesterol gallstones are related to insulin resistance which, in association with obesity, has reached an epidemic level worldwide. Experimental studies show that hyperinsulinemia, a key feature of insulin resistance, may cause increased hepatic cholesterol secretion and cholesterol supersaturation of bile and gallbladder dysmotility, and thereby may enhance gallstone formation. Insulin resistance syndrome can be modified by environmental factors, including dietary factors. The impact of diet on insulin sensitivity is mediated by both dietary composition and its energy content. The contribution of specific dietary elements to the prevalence and incidence of cholesterol gallstone disease has been explored in animal and human studies. There is considerable evidence to suggest that different types of fatty acids, independent of the total amount of fat consumption, affect insulin sensitivity and cholesterol gallstone disease differently. The effects of salt intake, consumption of protein and carbohydrates, and alcohol drinking on insulin resistance are controversial. Additional intervention trials and controlled experimental feeding studies are needed to further clarify these relationships and to provide useful prophylactic and therapeutic strategies.

The synthesis of MP-CDCA conjugates and dissolution kinetics of model cholesterol gallstones. Acta Biomater 2008; 4:1421-6. [PMID: 18501688 DOI: 10.1016/j.actbio.2008.01.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2007] [Revised: 11/28/2007] [Accepted: 01/15/2008] [Indexed: 11/22/2022]
Abstract
The comb-like copolymers of polycarboxylic acid were synthesized and then reacted with chenodeoxycholic acid (CDCA) to obtain a series of conjugates, MPn-CDCA, where n is the number of the groups of oxyethylene in each graft chain. This was confirmed by infrared spectroscopy and thin-layer chromatography. We investigated the effects of dissolving model cholesterol gallstones with the MPn-CDCA conjugates in phosphate-buffered saline at pH 7.4. The dissolution rates of CDCA, MP40-CDCA, MP30-CDCA, MP20-CDCA and MP10-CDCA were 5.33, 5.717, 17.59, 6.868 and 9.615x10(-7)kgm(-2)s(-1), micellar solubilities were 0.2431, 3.095, 12.972, 5.248 and 5.790kgm(-3) and total resistances were 5.33, 5.717, 17.59, 6.868 and 9.615x10(-7)kgm(-2)s(-1), respectively. These studies suggested that the interfacial resistance was the dominant rate-determining factor in dissolving model cholesterol gallstones. Model cholesterol gallstones could be more effectively dissolved by increasing the steric interactive potential energy of side chains and ensuring that the hydrophilic-lipophilic properties of MP-CDCA are within an appropriate range. The micellar dissolution rates of model cholesterol gallstones by MP20-CDCA were significantly faster than by the other conjugates.

Abstract
BACKGROUND Adenosine triphosphate-binding cassette (ABC) transporters ABCG5 and ABCG8 are sterol export pumps regulating biliary cholesterol excretion. The formation of gallstones, supersaturated with cholesterol in bile, is determined by genetic and environmental factors. The interaction of susceptible gene polymorphisms with age, sex and body mass index in gallstone disease is unclear. METHODS In a cross-sectional study, 979 subjects (880 men and 99 women, mean(s.d.) age 47.7(10.4) years) were recruited from a hospital-based population. Of these, 74 were diagnosed with gallstone disease by abdominal ultrasonography. Five non-synonymous polymorphisms, E604Q (ABCG5), D19H, C54Y, T400K and A632V (ABCG8), were analysed using the TaqMan genotyping assay. RESULTS The serum total cholesterol and both low- and high-density lipoprotein cholesterol levels were significantly lower in subjects with gallstones than in those without. 604Q (CC) and D19H (GC) genotypes were significantly associated with gallstone disease, even when adjusted for age, sex and body mass index. The genetic risk of developing gallstone disease was further stratified by age. The risk was greatly increased in subjects younger than 50 years with the D19H genotype and those of 50 years or more with the 604Q genotype. CONCLUSION Carriers of ABCG5 604Q or ABCG8 D19H polymorphisms have an increased risk of gallstone disease independent of age, sex and body mass index.

Abstract
The number of gallstone patients is increasing in ageing populations with a high prevalence of metabolic syndrome and obesity. Recently variants of hepatic ATP binding cassette transporters have been identified as genetic susceptibility factors for gallstone disease, pointing to novel means for risk assessment and prevention. Although laparoscopic cholecystectomy is the mainstay of therapy for symptomatic gallbladder stones, the clinical management of gallstone disease is changing rapidly, with an increase in day case surgery and the advent of transluminal endoscopic surgery. Here, we summarize the molecular and genetic mechanisms of gallstone formation as well as the current evidence-based algorithms for diagnosis and therapy of gallbladder and bile duct stones.

Abstract
BACKGROUND & AIMS Cholesterol cholelithiasis is one of the most prevalent and most costly digestive diseases in developed countries and its incidence has increased markedly in Asian countries owing to the adoption of Western-type dietary habits. Because animal experiments showed that high efficiency of intestinal cholesterol absorption contributes to gallstone formation, we explored whether the potent cholesterol absorption inhibitor ezetimibe could prevent gallstones and promote gallstone dissolution in mice and reduce biliary cholesterol content in human beings. METHODS Male gallstone-susceptible C57L mice were fed a lithogenic diet and concomitantly administered with ezetimibe at 0, 0.8, 4, or 8 mg/kg/day for 8 or 12 weeks. Gallbladder biles and gallstones were examined by microscopy. Gallbladder emptying in response to cholecystokinin octapeptide was measured gravimetrically. Biliary lipid outputs were analyzed by physical-chemical methods. Cholesterol absorption efficiency was determined by fecal dual-isotope ratio and mass balance methods. Lipid changes in gallbladder biles of gallstone patients vs overweight subjects without gallstones were examined before (day 0) and at 30 days after ezetimibe treatment (20 mg/day). RESULTS Ezetimibe prevented gallstones by effectively reducing intestinal cholesterol absorption and biliary cholesterol secretion, and protected gallbladder motility function by desaturating bile in mice. Treatment with ezetimibe promoted the dissolution of gallstones by forming an abundance of unsaturated micelles. Furthermore, ezetimibe significantly reduced biliary cholesterol saturation and retarded cholesterol crystallization in biles of patients with gallstones. CONCLUSIONS Ezetimibe is a novel approach to reduce biliary cholesterol content and a promising strategy for preventing or treating cholesterol gallstones by inhibiting intestinal cholesterol absorption.

Abstract
Capsule studies can be reviewed by varying rates and speeds; however, the presence of significant debris is frustrating to the reviewer much like the excessive stool that tends to hinder the progress of a colonoscopist. Numerous studies have been published in regards to the advantages of an ideal preparation in the setting of capsule endoscopy. This most recent study by Wei et al. is another study that has demonstrated that a colonic preparation, in this situation, combined with simethicone given just prior to the capsule study results in improved visibility of the mucosa. In theory, this will lead to an improved diagnostic ability to limit excessive reading duration.

Abstract
Gallstone disease is one of the most prevalent gastrointestinal diseases with a substantial burden to health care systems that is supposed to increase in ageing populations at risk. Aetiology and pathogenesis of cholesterol gallstones still are not well defined, and strategies for prevention and efficient nonsurgical therapies are missing. This review summarizes current concepts on the pathogenesis of cholesterol gallstones with focus on the uptake and secretion of biliary lipids and special emphasis on recent studies into the genetic background.
