Occurrence of dietary risk factors in inflammatory bowel disease: Influence on the nutritional status of patients in clinical remission.

BACKGROUND: Among the complex factors that may favor the occurrence of inflammatory bowel disease (IBD), genetic, immunological and environmental initiators, including nutritional factors, are listed. So far, there have been no previous studies on the type and frequency of dietary risk factors for IBD in Poland and their effect on the nutritional status of patients. OBJECTIVES: The aim of the study was to assess the influence of the frequency and type of dietary risk factors for IBD on the nutritional status of patients with ulcerative colitis (UC) and Crohn's disease (CD). MATERIAL AND METHODS: In the study, the dietary habits and nutritional status of patients were assessed using the cross-check dietary history method and the Mini Nutritional Assessment (MNA) questionnaire. The study group consisted of 162 IBD patients: 61 individuals with CD and 101 with UC. The data was compared to the results of a control group (129 healthy volunteers). RESULTS: The results obtained showed that IBD patients during a period of remission disclosed such dietary risk factors as inadequate consumption of fiber and excessive consumption of red meat and meat products, animal fats, and sugars in comparison to the control group. Only low fiber intake was associated with a worse nutritional status of patients with UC. No consistent influence of the number of IBD dietary risk factors on the nutritional status of patients was found. CONCLUSIONS: The nutritional status of IBD patients in remission was related to the type of dietary risk factors, but did not depend on the number of them.

Stool patterns and symptoms of disordered anorectal function in patients with inflammatory bowel diseases.

BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) typically clinically manifest with symptoms like chronic diarrhea, cramps, abdominal pain, and rectal bleeding. However, symptoms of abnormal anorectal function seem to be of equal importance, regardless of the presence or absence of perianal disease. OBJECTIVES: The aim of this study was to assess stool patterns and the prevalence of symptoms of disordered anorectal function, particularly urgency and fecal incontinence, and their severity in patients with inflammatory bowel diseases (IBDs). MATERIAL AND METHODS: Thirty-three patients with CD and 38 patients with UC completed a questionnaire. A push/strain maneuver was performed on all patients and 20 controls. RESULTS: Thirty-three patients had more than 3 bowel movements a day; 44 had loose/watery stools. Two patients had fewer than 3 bowel movements a week, 8 had hard/lumpy stools, and 3 used laxatives. Excessive straining and incomplete evacuation were reported by 17 and 38 patients, respectively. Fifty-two patients complained of urgency and 32 of tenesmus. Significantly, more UC patients than CD patients had urgency at least once a day (p < 0.04). The following symptoms were reported by patients in the following numbers: fecal incontinence (31), passive (20) and urge incontinence (16), incontinence to gas (24), as well as liquid (33) and solid stool (7). Stool/gas discrimination was defective in 28 patients. Eleven patients had to wear pads. Everyday functioning was worsened because of urgency/tenesmus in 39 patients and because of fecal incontinence in 28 patients. The push/strain maneuver was abnormal in 12 patients with CD, 15 patients with UC and 1 control subject. The differences between the 2 study groups and the controls were significant (p < 0.03 and p < 0.01). CONCLUSIONS: A majority of patients with IBD complain of urgency. Fecal incontinence is reported by over 50% of patients. Both worsen patients' everyday functioning. A relevant proportion of patients have symptoms consistent with constipation, which is in connection with an abnormal push/strain maneuver in more than 1/3 of them.

Diagnostic challenges in celiac disease.

Diagnosis of celiac disease in adults is currently based on serologic tests in combination with histopathological assessment of small intestinal biopsy specimens. High titers of celiac-specific antibodies in immunocompetent patients with villous atrophy in a good quality biopsy sample allow us to state a confident diagnosis. The relief of symptoms and histological improvement after embarking on a gluten free diet further support the initial diagnosis. However, in some cases, these conditions are not fulfilled, which requires a critical evaluation of laboratory and histopathology results and a consideration of other potential causes for the observed pathologies. To avoid diagnostic uncertainty, both biopsy and laboratory testing should be performed on a diet containing gluten. Immune deficiency, cross reaction of antibodies and possibilities of seronegative or latent celiac disease should be considered while evaluating serology results. Uneven distribution and variable intensity of histopathological changes in the small intestine along with multiple disorders presenting a similar specimen image may lead to invalid biopsy results. Additional laboratory testing and careful examination of a patient's history may deliver important data for a differential diagnosis and a more specific biopsy evaluation. Persistence or recurrence of symptoms, despite the ongoing treatment, requires a revision of the initial diagnosis, an evaluation of the gluten free diet and a search for concurrent disorders or complications.

Pancreatic duct stones: A report on 16 cases.

BACKGROUND: Pancreatolithiasis occurs in less than 1% of the general population and is mainly recognized in patients with chronic pancreatitis. Selection of the appropriate treatment method depends on the location, size and number of stones. OBJECTIVES: The aim of the study was to analyze data concerning patients with pancreatic duct stones who were hospitalized at Wroclaw Medical University's Department of Gastroenterology and Hepatology from 2010 to 2014. MATERIAL AND METHODS: The study presents data on 16 patients with pancreatic duct stones, who constituted 7% of all 228 patients with chronic pancreatitis hospitalized at the Department in the study period. The clinical data were compared with findings reported in the literature. RESULTS: Epigastric pain was the most common symptom reported by patients with pancreatolithiasis. The sensitivity of imaging tests in the diagnosis of pancreatic duct stones was as follows: abdominal ultrasonography - 31%, endoscopic retrograde cholangiopancreatography (ERCP) - 67%, computed tomography - 71%, endoscopic ultrasonography - 73%. In 6 patients ERCP and sphincterotomy were performed along with stenting of the main pancreatic duct. Three other subjects were qualified for surgical treatment. In 7 selected patients conservative treatment and further observation were applied. CONCLUSIONS: Endoscopic ultrasonography is characterized by high sensitivity in the diagnosis of pancreatic duct stones. ERCP is the first-line treatment in the case of a small number of stones with sizes below 5 mm located in the head or body of the pancreas. In the case of stones with sizes ≥ 5 mm, extracorporeal shock wave lithotripsy should be performed before endoscopic drainage during ERCP. Stenosis of the main pancreatic duct is the key risk factor for the recurrence of pancreatolithiasis.

Inadequate seroprotection against hepatitis B virus and one detected case of hepatitis C virus infection among patients with inflammatory bowel disease.

OBJECTIVES: The prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among patients with inflammatory bowel disease (IBD) from central and eastern European countries is unknown. Postvaccination HBV immunity in an immunocompromised host may wane. The aims of the study were as follows: to assess the immune status for HBV and HCV among IBD patients, the level of HBV seroprotection, and to compare the immune status of patients who received mandatory versus recommended HBV vaccination. MATERIALS AND METHODS: Serological markers of HBV and HCV (anti-HBs, anti-HBc, HBsAg, and anti-HCV) were determined in 147 consecutive IBD patients. An anti-HBs of 10 IU/l or more was considered as immunity to HBV infection. RESULTS: HBV infection was detected in 21 patients, whereas 11 of them recalled previous HBV vaccination. Sixty-eight noninfected patients had a level of anti-HBs 10 IU/l or more and only 29% reached the cut-off level of 100 IU/l. Among patients vaccinated obligatorily, two patients had previous HBV infection and 15% did not have an adequate seroprotection against HBV. Patients who received a mandatory HBV vaccine more frequently had a protective anti-HBs level than those vaccinated voluntarily (P<0.001). One positive anti-HCV result was found. CONCLUSION: A mandatory HBV vaccination significantly increased the number of patients effectively protected against HBV; however, a remarkable number of vaccinated IBD patients had inadequate HBV seroprotection. All IBD patients should be screened for HBV and HCV infections and monitored for anti-HBs titers.

The HLA-DQß1 insertion is a strong achalasia risk factor and displays a geospatial north-south gradient among Europeans.

Idiopathic achalasia is a severe motility disorder of the esophagus and is characterized by a failure of the lower esophageal sphincter to relax due to a loss of neurons in the myenteric plexus. Most recently, we identified an eight-amino-acid insertion in the cytoplasmic tail of HLA-DQß1 as strong achalasia risk factor in a sample set from Central Europe, Italy and Spain. Here, we tested whether the HLA-DQß1 insertion also confers achalasia risk in the Polish and Swedish population. We could replicate the initial findings and the insertion shows strong achalasia association in both samples (Poland P=1.84 × 10(-04), Sweden P=7.44 × 10(-05)). Combining all five European data sets - Central Europe, Italy, Spain, Poland and Sweden - the insertion is achalasia associated with Pcombined=1.67 × 10(-35). In addition, we observe that the frequency of the insertion shows a geospatial north-south gradient. The insertion is less common in northern (around 6-7% in patients and 2% in controls from Sweden and Poland) compared with southern Europeans (~16% in patients and 8% in controls from Italy) and shows a stronger attributable risk in the southern European population. Our study provides evidence that the prevalence of achalasia may differ between populations.

A Case of Severe Ulcerative Colitis with Colonic Dilatation caused by Renal Mucinous Tubular and Spindle Cell Carcinoma.

We present a case of ulcerative colitis (UC) in a patient during the first severe relapse with colonic dilatation and coexisting of giant renal tumor. Kidney tumor was constricting on colon and imitating toxic megacolon (TM). The patient with severe acute colitis (SAC) was admitted to the Department of Gastroenterology and Hepatology with inflammatory bowel disease (IBD) diagnosed in the previous month, based on clinical symptoms, endoscopy, and histopathology results. Computed tomography (CT) revealed a giant left kidney tumor without evidence of infiltration, a dilatation of the transverse colon up to 6 cm, and narrow light of the descending colon. There were no signs of intestinal obstruction or perforation. The control X-rays revealed maintaining megacolon, with dilatation of splenic flexure projection up to 6.5 to 7.5 cm. The patient was treated conservatively with no apparent improvement and finally operated on. Intraoperatively, a large tumor of the kidney (12 cm) constricting intestine was revealed. Left-sided nephrectomy and partial resection of the colon with the emergence of a colostomy was performed. The histopathology exam revealed renal mucinous tubular and spindle cell carcinoma (RMTSCC), a very rare malignant kidney tumor of low malignant potential and relative good prognosis. It was identified in the past 20 years. To date, approximately 100 such cases of cancer have been described.

Overuse of proton pump inhibitors.

Proton pump inhibitors (PPIs) are currently the most effective drugs inhibiting hydrochloric acid secretion. They have replaced histamine type 2 receptor antagonists in the majority of clinical indications, for example, functional dyspepsia, gastroesophageal reflux disease, or drug­induced upper gastrointestinal tract injury. High prevalence of acid­related upper gastrointestinal tract diseases, as well as the potency, good tolerance, and acceptable costs of treatment with PPIs have largely increased their use in hospitals and outpatient clinics. At present, PPIs are used more frequently, often long­term and in high doses, and not necessarily according to the current recommendations. PPI­induced inhibition of hydrochloric acid secretion causes iatrogenic hypochlorhydria and hypergastrinemia, which may result in parietal cell hypertrophy and enterochromaffin­like cell hyperplasia, exposing patients to rebound hydrochloric acid hypersecretion. It is believed that this phenomenon may be responsible for failure to discontinue pharmacotherapy with PPIs and to their overuse. As a result, an inappropriate, especially chronic, treatment increases the risk of some side effects as well as individual and institutional expenditures. Therefore, a reasonable approach to clinical indications, dosing, and treatment regimen in each individual patient should be recommended.

Genetic polymorphism of ABCB1 gene (C3435T) in patients with inflammatory bowel diseases. Is there any gender dependency?

BACKGROUND: In recent years, an increasing incidence of inflammatory bowel disease (IBD) has been reported, mainly as Crohn's disease (CD) and ulcerative colitis (UC). The individual susceptibility, the disease's course and response to the applied therapy is likely due to genetic factors such as ABCB1 gene mutations, exemplified by C3435T polymorphism. The aim of the study was to evaluate the distribution of C3435T polymorphism regarding the gender in IBD patients and control subjects from Lower Silesia region and its possible association with IBD susceptibility. METHODS: The research was conducted in groups of 61 IBD patients and 101 healthy subjects from the Lower Silesia region. Polymorphism of C3435T was determined using PCR-RFLP method. RESULTS: Frequency distributions of C3435T genotype and of 3435T or 3435C gene alleles of IBD, CD or UC patients were compared to control group; each treated as a whole or split further by gender. The statistically significant correlation was discovered between gender and C3435T genotype both for IBD and CD patients, with 3435CT heterozygote prevailing in IBD and CD males. Odds ratio calculations revealed statistically significant difference for the 3435CT genotype between control and: IBD group considered as a whole; IBD males; CD males; and for 3435TT variant between control and IBD males. Conclusions. The 3435CT genotype could be a risk factor for IBD and CD in men. The 3435TT genotype in males seems to be associated with the lower chance of IBD presence.

A 'cocoon immunization strategy' among patients with inflammatory bowel disease.

BACKGROUND AND AIMS: A 'cocoon strategy' is defined as the strategy of protecting vulnerable patients from infectious diseases by vaccinating those in close contact with them. In our study, we evaluate the vaccination status among children living with patients with inflammatory bowel disease (IBD) to determine the realization of the cocoon strategy and to identify characteristics associated with pediatric vaccine refusal. PATIENTS AND METHODS: A self-completed survey was conducted on 136 hospitalized patients with IBD. The survey comprised questions about household child vaccination coverage, the reasons for vaccine refusal, and the history of infectious diseases among the patients. RESULTS: Fifty-six patients reported living with children. Forty percent of children were vaccinated with at least one of the recommended vaccines. Most frequently, children received pneumococcal (26%) and rotaviruses (22%) vaccines. The most common reason for nonimmunization was patients' opinion that immunizations are not necessary for them (52%). There was a statistically significant association between the nonreimbursed vaccines coverage and the educational level of the patients (P<0.0001). Despite the fact that 28% of the patients could not definitively recall varicella infection, none of them and none of the children in their household had been vaccinated against chickenpox. CONCLUSION: The use of nonmandatory vaccines recommended in family members of patients with IBD is insufficient. Further vaccine promotion and education of patients as well as their healthcare providers is required. A particular concern is associated with the pneumococcal, influenza, rotaviruses, and varicella infections. Nonimmunized and varicella-zoster virus-seronegative patients should be vaccinated, and in case of immunosuppression, vaccination of children in the household is required.

Economic implications of biological therapy for Crohn's disease.

In the early 90s American authors estimated that if a theoretical new drug was introduced that was capable of changing the natural course of the disease and reducing direct non-drug medical costs (including hospitalisation and surgery) by 20%, despite doubling the overall drugs bill, there would still be a reduction in total direct medical costs of Crohn's disease by 13%. Infliximab proved to be efficacious in reducing and maintaining remission in moderate to severe active Crohn's disease and/or fistulising Crohn's disease. A higher acquisition cost still remains its major limitation. Currently only the use of infliximab in case of treatment for flares seems to be cost-effective. However, this statement may be modified in the near future.

Associations between the lower esophageal sphincter function and the level of physical activity.

BACKGROUND: Gastroesophageal reflux disease (GERD) is a very frequent and multifactorial disease. It has been found that GERD is associated with obesity, smoking, esophagitis, diet and lifestyle. Physical activity is among the factors involved in the occurrence of GERD. OBJECTIVES: The aim of the study was to evaluate the associations between the different parameters of lower esophageal pressure (LES) and the level of everyday physical activity in patients with GERD. MATERIAL AND METHODS: The authors examined 100 consecutive patients who underwent manometry and pH-metry because of symptoms suggesting GERD. Physical activity was assessed by means of the International Physical Activity Questionnaire (IPAQ). In accordance with IPAQ categorical scoring, the authors divided the studied subjects into 3 groups according to their level of physical activity. The investigation comprised 59 men and 41 women, with the mean age 49 ± 14 years. RESULTS: The authors analyzed the relationships between the LES parameters (pressure, total LES length and HPZ length) and physical activity. The authors did not find any significant correlations between the studied parameters and the amount of physical activity. The authors also did not observe any association between the LES pressure and the level of physical activity. The subgroups distinguished on the basis of LESP did not differ as to the amount of everyday physical activity as well. CONCLUSIONS: Although most data indicates that intense exercise exacerbates GERD symptoms, the authors did not find any associations between LES parameters and physical activity. In view of the present results maintaining the recommended level of everyday physical activity does not interfere with the mechanisms of GERD.

The influence of deficiencies of essential trace elements and vitamins on the course of Crohn's disease.

In patients with Crohn's Disease (CD), malnutrition is frequently observed and is an important complication, frequently associated with nutritional deficiencies, especially vitamins (both water- and fat-soluble) and essential trace elements. It is often a result of the disease activity, poor oral intake and/or restrictive diets. Nutrition plays an important role in disease management and helps to maintain remission in CD patients. Deficiencies occur in patients with active Crohn's disease, and also in those in remission. Specific supplementation of vitamins and micro- and macronutrients might be helpful or even necessary in this group of patients. This review outlines the most frequent nutritional deficiencies and their complications in relation to the Crohn's Disease Activity Index, and provides an overview of therapeutic perspectives for CD patients in adult patients with inflammatory bowel disease (IBD). Biological therapy, which is being used with increasing frequency, seems not only to mitigate the inflammatory process in the gastrointestinal tract, but also has significant impact on the nutritional status of patients with Crohn's disease.

Lipid peroxidation markers in Crohn's disease: the associations and diagnostic value.

BACKGROUND: Crohn's disease (CD) is an incurable and difficult to diagnose condition. While high sensitive C-reactive protein (CRP) remains the best biochemical marker, we evaluated the diagnostic usefulness of lipid peroxidation indices. METHODS: Malondialdehyde/thiobarbituric acid-reactive substances (MDA/TBARS), peroxidation potential (PP), lipid hydroperoxides (ROOH), oxidized-low density lipoprotein (oxLDL), and oxLDL antibodies (OLAB) were assessed in 52 CD patients and 99 volunteers and referred to clinical activity, inflammation, nutritional and antioxidant status. RESULTS: MDA/TBARS were higher in CD while oxLDL and PP decreased in active disease and ROOH and OLAB did not differ. oxLDL and PP negatively and OLAB positively correlated with CD activity. MDA/TBARS positively correlated with IL-6 and SOD-1 and negatively with catalase. IL-6 and SOD-1 explained 24% in MDA/TBARS variability. PP negatively correlated with CRP, platelets, and IL-6 and positively with glutathione peroxidase-1, paraoxonase-1, cholesterol, triglycerides, and albumins. Cholesterol and CRP explained 57% in PP variability. oxLDL negatively correlated with IL-1 and IL-6 and positively with glutathione peroxidase-1, paraoxonase-1, cholesterol, and albumins. Paraoxonase-1 explained 17% of oxLDL variability. OLAB positively correlated with IL-1 explaining 10% in its variability and negatively with cholesterol. MDA/TBARS were the best predictor of CD, comparable to CRP, with high specificity (MDA/TBARS sensitivity and specificity: 75% and 90%; CRP: 76% and 93%). Combined assessment of MDA/TBARS and CRP improved sensitivity (94%) corresponding with acceptable specificity (81%). CONCLUSIONS: MDA/TBARS are elevated in CD and may help to rule the disease out, while the combined evaluation with CRP may serve for CD confirmation. oxLDL and PP depended on substrate availability, decreased in CD.

Phase I, double-blind, randomized, placebo-controlled, dose-escalation study of NI-0401 (a fully human anti-CD3 monoclonal antibody) in patients with moderate to severe active Crohn's disease.

BACKGROUND: NI-0401 is a fully human monoclonal antibody, which binds to the CD3 subunit of the T-cell receptor, causing modulation of T-cell activity. We investigated the safety and the ability to modulate the TCR-CD3 complex of NI-0401 in patients with active Crohn's disease (CD). METHODS: A double-blind, placebo-controlled, randomized, multicenter, dose-escalating trial was conducted in CD patients age 18-70 years, a Crohn's Disease Activity Index (CDAI) of 220-450, and detectable levels of C-reactive protein. The primary outcome was safety and the ability of NI-0401 to modulate the TCR-CD3 complex on T cells. Efficacy parameters included the proportion of patients achieving remission (CDAI <150), clinical response (CDAI fall ≥100), and change from baseline in the CD Endoscopy Index of Severity (CDEIS). RESULTS: Forty patients received placebo (n = 7) or NI-0401 (n = 33) 0.05-10 mg daily for 5 days. NI-0401 doses ≤1 mg were well tolerated. Infusion reactions occurred at doses ≥2 mg. The extent and duration of TCR-CD3 modulation increased with dose. No differences between groups were observed in the proportions of patients achieving clinical remission or response. The mean CDEIS at week 6 differed significantly between the 1-mg and placebo group. CONCLUSIONS: NI-0401 was tolerated at doses ≤1 mg with manageable side effects. NI-0401 induced a dose-dependent modulation of the TCR-CD3 complex. No significant improvement of CDAI was observed but 1 mg NI-0401 demonstrated an improvement in CDEIS.

Anorectal function and visceral hypersensitivity in celiac disease.

OBJECTIVE: To evaluate anorectal function and rectal sensitivity thresholds in patients with celiac disease (CD). METHODS: In 25 unselected patients with CD (16 female, 9 male; mean age 45, range 24 to 75 y) and 20 controls (12 female, 8 male; mean age 41, range 20 to 65 y) anorectal manometry and rectal balloon distension test were conducted using a 4 lumen water perfused catheter with a polyethylene balloon (Zinectics Manometric Catheter, Medtronic). RESULTS: In celiac patients the maximal anal resting pressure, reflecting the internal anal sphincter function, was significantly higher than that in the controls: 87.8±21.7 mm Hg versus 66.7±15.2 mm Hg (P<0.001). There were no considerable differences between both the groups neither in the maximal anal squeeze nor in the cough pressures. Celiac patients had significantly lower first sensation threshold: 25.6±10.8 mL versus 37.5±12.5 mL (P<0.05). Visceral hypersensitivity (rectal pain/discomfort threshold ≤100 mL) was observed in 36% of celiac patients and in none of the controls (P<0.01). CONCLUSIONS: The increased anal resting pressure and rectal hypersensitivity are observed in CD. Disturbances in gastrointestinal motility and visceral perception in the course of CD may occur at different levels of the brain-gut axis including direct changes in the enteric nervous system.

Anorectal function and dyssynergic defecation in different subgroups of patients with irritable bowel syndrome.

PURPOSE: The purpose of this study was to evaluate anorectal function in different subgroups of patients with irritable bowel syndrome (IBS), including those with mixed bowel habits. MATERIALS AND METHODS: Sixty-six IBS patients selected according to Rome III criteria (39 female and 27 male patients; mean age, 41.5 +/- 15.4) and 20 subjects in the control group (13 female and 7 male patients; mean age, 41.4 +/- 13.7) were examined. The IBS patients were divided into three subgroups according to bowel movement pattern: patients with constipation (27%), patients with diarrhea (27%), and patients with mixed bowel habits (46%). Anorectal manometry and rectal distension test were performed using a four-lumen water-perfused catheter with a polyethylene balloon. RESULTS: No significant differences in manometric parameters between the subgroups of IBS patients and the control group were found, except for pelvic floor dyssynergia (PFD), which was more frequent in all subgroups of IBS (41% of patients) than in controls (5% of subjects) (p < 0.01). Lower rectal pain threshold was observed particularly in IBS patients with diarrhea and mixed bowel habits (p < 0.01). CONCLUSION: Manometric parameters characterizing anal sphincter function are not correlated with the predominant bowel movement pattern in IBS. The features of PFD are significantly more frequent in all subgroups of IBS patients than in controls, suggesting that, in general, IBS patients show changes in the mobility of the pelvic floor. Hypersensitivity to rectal distension is commonly observed in IBS, but it does not seem to be a highly specific marker of the disorder.

Impaired erythrocyte antioxidant defense in active inflammatory bowel disease: impact of anemia and treatment.

BACKGROUND: Oxidative stress contributes to the propagation and exacerbation of inflammatory bowel disease (IBD) but the status of erythrocyte antioxidant defense remains unknown. METHODS: Erythrocyte activities of superoxide dismutase-1 (SOD1), catalase, and glutathione peroxidase-1 (GPx1) were determined in 174 IBD patients and 105 controls and referred to IBD activity, inflammation severity, nutritional status, systemic oxidative stress, anemia, and treatment. RESULTS: Catalase and GPx1 activities were decreased in active IBD, whereas SOD1 became upregulated by IBD-related oxidative stress. In Crohn's disease (CD) corticosteroids decreased SOD1 activity. SOD1 correlated indirectly with CD activity and erythrocyte sedimentation rate (ESR) and directly with transferrin. In ulcerative colitis (UC) anemia downregulated SOD1. Decreases in GPx activity corresponded with IBD activity, anemia, inflammation, and malnutrition. Oxidative stress in UC and corticosteroids in CD also downregulated GPx. Catalase activity was decreased by CD-related anemia, correlating directly with hemoglobin, and indirectly with CD activity, inflammatory and protein oxidative stress markers. When co-analyzed, anemia but not CD activity significantly contributed to catalase downregulation. In UC, catalase activity corresponded indirectly with UC endoscopic activity and inflammation and directly with hemoglobin. UC activity, anemia, and treatment with azathioprine negatively affected catalase. As indicators of active IBD, GPx1 showed a diagnostic accuracy of 73%, whereas catalase showed 63% as compared to 74% of C-reactive protein and ESR. CONCLUSIONS: Erythrocyte antioxidant defense is impaired in active IBD. SOD1, GPx1, and CAT activities are differently affected by the disease type, activity, anemia, inflammation, oxidative stress, and treatment. As an active IBD indicator, GPx1 was comparable to C-reactive protein and ESR.

Assessment of dietary intake of patients with irritable bowel syndrome.

The dietary intake of patients with irritable bowel syndrome was assessed using 24-h dietary recall. The energy value and nutrient contents in the daily food rations were calculated by Nutritionist IV computer program with the Polish database. Differentiations in the Polish RDA coverage for energy and nutrients were observed in the studied group. Fat, saturated fatty acid, phosphorus and also vitamin A, E and C contents were above the RDA in the patients' daily food ration. The majority of IBS individuals did not meet recommendations for carbohydrate intake. Calcium and cooper intake was below the Polish RDA. The insufficient vitamin B2 intake and excessive Fe supply have been shown in the male patients.

[Costs and range of health care consumption under general health insurance and sick leaves among patients with inflammatory bowel disease in chosen countries -- a literature review]. / Koszty i zakres korzystania ze swiadczen zdrowotnych w ramach powszechnego ubezpieczenia zdrowotnego oraz czasowa niezdolnosc do pracy u pacjentów z nieswoistymi zapaleniami jelit w wybranych krajach -- przeglad pismiennictwa.

Inflammatory bowel disease (IBD) is considered to be common in the developed countries of Europe and in North America. A chronic nature of the disease, bowel and systemic symptoms debilitating daily functioning, coexisting extraintestinal complications, recurrent, not infrequently severe and unpredictable clinical course significantly lower patients' quality of life. When compared with the general population, IBD patients more often take use of health care services. They also experience more episodes of sick leave, which is associated with a greater number of sick leave days per year.
