Dermal lesions associated with anti-tumor necrosis factor-α therapy in patients with inflammatory bowel disease: findings from an inflammatory bowel disease tertiary center in Poland.

INTRODUCTION: There is little data on the development of dermal lesions in patients with inflammatory bowel disease (IBD) treated with anti - tumor necrosis factor-α (anti-TNF-α), while their characteristics, clinical course, and impact on treatment are of great concern. OBJECTIVES: The aim of this study is to assess the prevalence, risk factors, and clinical sequelae of dermal lesions in IBD patients treated with anti-TNF-α antibodies. PATIENTS AND METHODS: This retrospective, single-center study evaluated 541 IBD patients treated with anti-TNF-α drugs and compared them with 688 IBD anti-TNF-α-naïve patients. RESULTS: A significant higher prevalence of dermal lesions was noted during the anti-TNF-α therapy of 30.9% patients versus 16.4% (P <0.001). Risk factors for dermal lesions were higher body mass index (BMI), Crohn's disease located in the small intestine, and longer duration of therapy. Some types of dermal lesions were associated with anti-TNF-α therapy: infusion reactions and injection site reactions, cutaneous infection, psorasiform reactions, and lupus-like symptoms. Dermal lesions (alopecia, lupus-like symptoms, melanoma, and psoriasis) occurred in 5.9% of patients who discontinued or changed anti-TNF-α therapy. CONCLUSIONS: We observed a higher prevalence of dermal lesions in patients with IBD undergoing anti-TNF-α therapy, although the development of such lesions rarely necessitated a change in or discontinuation of treatment. Patients with IBD should undergo regular dermatological follow-up, which may improve the detection of dermal lesions. Moreover, biological therapy in IBD patients requires close collaboration with an experienced dermatologist.

SARS-CoV-2 vaccination in inflammatory bowel disease (IBD) patients - does treatment for IBD negatively affect SARS-CoV-2 antibodies? A single-centre, prospective study.

Introduction: Inflammatory bowel disease (IBD) patients use a wide variety of immunosuppressive drugs, including biologics, but their effect on SARS-CoV-2 vaccine antibody levels remains a mystery. Aim: We analysed whether the drugs used in the treatment of IBD patients could affect the concentration of SARS-CoV-2 antibodies. Material and methods: This is a prospective, single-centre evaluation of the persistence of SARS-CoV-2 antibodies after vaccination at various time points: every 2 months throughout the 6th month after the first dose. Results: We included a total of 346 vaccinated IBD patients in the study. A negative correlation between antibody level and time from full vaccination was confirmed for the following types of therapy: infliximab (rho = -0.32, p < 0.001), adalimumab (rho = -0.35, p = 0.025), and vedolizumab (rho = -0.50, p < 0.001). In the case of other, long-term drug administration, a negative correlation between antibody level and time from full vaccination was confirmed for mesalazine (rho = -0.35, p < 0.001), budesonide (rho = -0.58, p = 0.004), systemic glucocorticoids (rho = -0.58, p < 0.001), and azathioprine (rho = -0.44, p < 0.001). Conclusions: Due to the immunosuppressive and biological treatment, IBD patients are exposed to a shorter persistence of SARS-CoV-2 antibodies and require booster doses. The role of gastroenterologists in educating patients about the need to continue SARS-CoV-2 vaccination remains crucial.

Pharmacokinetic interaction between regorafenib and atorvastatin in rats.

BACKGROUND: Regorafenib is used in the treatment of colorectal cancer and hepatocellular carcinoma. Due to the co-morbidity of hyperlipidemia in these conditions, statins, including atorvastatin, are used as potential adjuvant therapy agents. Both regorafenib and atorvastatin are metabolized by CYP3A4. In addition, atorvastatin is a P-gp and BCRP substrate, whereas regorafenib and its active metabolites M-2 and M-5 are inhibitors of these transporters. Hence, the concomitant use of both drugs may increase the risk of a clinically significant drug-drug interaction. Therefore, the present study aimed to assess the pharmacokinetic interactions of atorvastatin and regorafenib and their active metabolites. METHODS: Male Wistar rats were assigned to three groups (eight animals in each) and were orally administered: regorafenib and atorvastatin (IREG+ATO), a carrier with regorafenib (IIREG), and atorvastatin with a carrier (IIIATO). Blood samples were collected for 72 h. UPLC-MS/MS was the method of measurement of regorafenib and atorvastatin concentrations. The pharmacokinetic parameters were calculated with a non-compartmental model. RESULTS: A single administration of atorvastatin increased the exposure to regorafenib and its active metabolites. In the IREG+ATO group, the Cmax, AUC0-t, and AUC0-∞ of regorafenib increased 2.7, 3.2, and 3.2-fold, respectively. Atorvastatin also significantly increased the Cmax, AUC0-t, and AUC0-∞ of both regorafenib metabolites. Regorafenib, in turn, decreased the AUC0-t and AUC0-∞ of 2-OH atorvastatin by 86.9% and 67.3%, and the same parameters of 4-OH atorvastatin by 45.0% and 46.8%, respectively. CONCLUSIONS: This animal model study showed a significant pharmacokinetic interaction between regorafenib and atorvastatin. While this interaction may be clinically significant, this needs to be confirmed in clinical trials involving cancer patients.

Gastrointestinal symptoms in COVID-19.

SARS-CoV-2 infection manifests mainly by involving the respiratory system. Due to the presence of abdominal symptoms, the digestive system is clearly involved in the expression, transmission, and possible pathogenesis of COVID-19. There are many theories regarding the development of abdominal symptoms, including angiotensin 2 receptor, cytokine storm, and disturbances of the intestinal microbiome. This paper provides an overview of the most important meta-analyses and publications on gastrointestinal symptoms and the gut microbiome in COVID-19.

Awareness and Compliance with the Recommendations of Primary and Secondary Prevention of Cancer in Patients with Inflammatory Bowel Disease.

INTRODUCTION: Patients with Inflammatory Bowel Disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are at high risk of developing malignancies, so prevention and adherence to cancer screening may improve detection. The aim of this study was to assess compliance with medical recommendations, especially primary and secondary prevention of cancer. METHODS: This one-center cross-sectional study was carried out between June and December 2021 amongst patients at the Department of Internal Medicine and Gastroenterology, IBD Division, National Medical Institute of Ministry of Interior Affairs and Administrations, or the outpatient clinic. Patients with IBD were asked to complete an anonymous questionnaire, which included 42 questions concerning lifestyle, cancer risk factors, cancer history, and checkups. STATISTICAL METHODS: The results of the qualitative variables were expressed as frequencies and percentages. We used Fisher's exact test and the Chi-squared test. A value of p < 0.05 was considered significant. Statistical analyses were performed with the SPSS statistical package. RESULTS: A total of 313 patients were enrolled in the study: 145 women and 168 men. In the group, 182 had Crohn's disease (CD), 120 had ulcerative colitis (UC), and 11 with IBDU (unclassified IBD). Most participants had a disease duration of over 8 years and received biological treatment, corticoids, and/or immunosuppressive therapy. Amongst respondents, 17% (31) of patients with CD and 25.8% (31) with UC were overweight, and 10.5% (19) with CD and 15.8% (19) with UC were obese (p = 0.017). We found that 16.3% of all respondents were smokers (79.6% (144) with CD, 90.8% (109) with UC, and 72.7% (8) with IBDU; p = 0.053), and 33.9% declared that they consumed alcohol (39.4% (71) with CD, 26.9% (32) with UC, and 18.2% (2) with IBDU; p = 0.045). A total of 25.4% of patients were exposed to UV radiation, but only 18.8% used sunblock. In addition, 58.8% (67) of patients with CD and 35.8% (19) with UC receiving immunosuppressants had regular laboratory tests (p = 0.02). Furthermore, 41.4% (46) of patients with UC, 27.1% (49) of patients with CD, and 70.0% (7) of patients with IBDU declared not to perform any dermatological control (p = 0.013). A total of 77% of patients had abdominal ultrasound. Out of 52.9% of patients for whom colonoscopy was recommended, only 27.3% had it performed (16.9% (30) with CD vs. 43.1% (50) with UC p < 0.001). Most examinations were ordered by gastroenterologists. Female patients had regular breast control (CD, 78.6% (66); UC, 91.2% (52); IBDU, 50% (2); p = 0.034), and 93.8% (76) had gynecological examinations. Additionally, 80.2% of patients knew about HPV, but most declared not to be vaccinated. A total of 17.9% of patients had urological control, but most had no important pathology detected. CONCLUSIONS: According to our study, many patients are still exposed to risk factors, such as obesity, smoking, and low physical activity, that are modifiable. Laboratory tests in patients with immunosuppressive treatment should be performed regularly. Systematic control, especially dermatological checkups, should be recommended. Additionally, not only gastrologists but also other specialists and GPs should remind patients about regular checkups. Primary prevention, such as HPV vaccinations, should be recommended to all patients.

Effect of Intravenous Iron Administration on Bone Mineral and Iron Homeostasis in Patients with Inflammatory Bowel Disease-Results of a Prospective Single-Centre Study.

INTRODUCTION: Anaemia and bone metabolism alterations are common in inflammatory bowel disease (IBD), which is a heterogeneous group of diseases that include Crohn's disease (CD) and ulcerative colitis (UC) with a rich intestinal and extraintestinal symptomatology. All these make the diagnostic procedures complicated and difficult. PURPOSE AND SCOPE: The aim of this study was to assess the effect of parenteral iron administration on biomarkers of mineral and bone homeostasis over time. MATERIALS AND METHODS: The study was a single-centre non-randomised prospective study. It was carried out between 2016 and 2020 in a group of patients in the Department of Internal Medicine and Gastroenterology Subunit of Inflammatory Bowel Diseases at the National Institute of Medicine of the Ministry of the Interior and Administration in Warsaw. At the first examination, the baseline disease severity, initial evaluation of anaemia (morphology, iron (Fe), total iron binding capacity (TIBC), ferritin, vitamin B12, folic acid) and bone mineral metabolism including C-reactive protein (CRP), albumins, alkaline phosphatase (ALP), Calcium, osteocalcin, phosphate in serum and in urine, parathyroid hormone (PTH), vitamin D3, fibroblast growth factor (iFGF23) and procollagen type 1N propeptide (P1NP) C-terminal telopeptide (CTX), was initially assessed. On the basis of peripheral blood counts, an appropriate dose of iron (iron derisomaltose or caboxymaltose) was administered. During the subsequent appointments on week 1, 4, and 12 morphology, iron (Fe), total iron binding capacity (TIBC), ferritin, vitamin B12, folic acid, C-reactive protein (CRP), albumins, alkaline phosphatase (ALP), Calcium, osteocalcin, phosphate in serum and in urine, parathyroid hormone (PTH), vitamin D3, fibroblast growth factor (iFGF23) and procollagen type 1N propeptide (P1NP) C-terminal telopeptide (CTX), were evaluated. RESULTS: A total of 56 patients were enrolled into the study: 24 women and 32 men. In the group, 32 patients had Crohn's disease (CD) and 24 had ulcerative colitis (UC). We found a statistically significant increase in the concentration of albumin (p = 0.031), haemoglobin (p < 0.001), haematocrit (p < 0.001), MCV (p < 0.001), MCHC (p = 0.001), iron (p < 0.001) and ferritin (p < 0.001) after the administration of parenteral iron. The influence of individual iron formulations on the analysed parameters (phosphate concentration in serum and in the urine, iFGF23, P1NP, PTH, vitamin D, haemoglobin and ferritin) was similar. Interestingly, an inverse correlation was found between the concentration of phosphorus in the blood and iFGF23 at certain time-points; however, in the study group they did not significantly affect the disturbances of calcium and phosphate metabolism. CONCLUSIONS: In the study group, transient and non-significant disorders of phosphate metabolism were found, which does not constitute a contraindication to treatment with parenteral iron in inflammatory bowel disease patients, which was safe and efficient.

Long-lasting dyspeptic symptoms - another consequence of the COVID-19 pandemic?

Introduction: It is known that the virus SARS-CoV-2 can attack the gastrointestinal (GI) tract and induce gastroenteritis. This can trigger a wide variety of disorders of gut-brain interaction (DGBIs) or functional gastrointestinal disorders (FGIDs), including post-infectious dyspepsia, which remains underestimated. Aim: To estimate the prevalence of dyspeptic symptoms following COVID-19, immediately after discharge and 3, 6, and 9 months after hospitalization. Material and methods: A prospective, single-centre evaluation of questions regarding functional dyspepsia (FD) as assessed by the Gastroduodenal Module of ROME IV Diagnostic Questionnaire for Adult FGIDs among 320 patients who had had COVID-19. Results: The FD ROME IV criteria were met at the respective time-points by 0.0% (0), 4.8% (12), 3.2% (8), and 3.2% (8) of cases. However, the presence of GI symptoms that suggested FD but did not meet the timeframe ROME IV criteria for FD were found in 9.6% (24), 23.5% (59), 20.7% (52), and 20.7% (52) of cases, respectively. Conclusions: The presence and persistence of gastrointestinal dyspeptic symptoms following COVID-19 is a significant problem. The timeframe of the Rome IV criteria may underestimate the number of patients with persistent dyspeptic symptoms following COVID-19 disease.

Risk Factors for Osteoporosis among Patients with Inflammatory Bowel Disease-Do We Already Know Everything?

INTRODUCTION: There are many known risk factors for osteoporosis (OST) among patients with inflammatory bowel disease (IBD), one of which is physical activity. MATERIAL AND METHODS: The aim of the study is to assess the frequency and risk factors of OST among 232 patients with IBD compared to a group of 199 patients without IBD. The participants underwent dual-energy X-ray absorptiometry, laboratory tests, and completed a questionnaire about their physical activity. RESULTS: It was found that 7.3% of IBD patients suffered from OST. Male gender, ulcerative colitis, extensive inflammation in the intestine, exacerbation of disease, rare physical activity, other forms of physical activity, past fractures, lower levels of osteocalcin, and higher levels of C-terminal telopeptide of type 1 collagen were risk factors for OST. As many as 70.6% of OST patients were rarely physically active. CONCLUSIONS: OST is a common problem in IBD patients. OST risk factors differ significantly between the general population and those with IBD. Modifiable factors can be influenced by patients and by physicians. The key to OST prophylaxis may be regular physical activity, which should be recommended in clinical remission. It may also prove valuable to use markers of bone turnover in diagnostics, which may enable decisions regarding therapy.

Bone Metabolism Alteration in Patients with Inflammatory Bowel Disease.

Background: Metabolic bone disease is a common disorder, but there is a lack of data on it in patients with inflammatory bowel disease (IBD). Methods: In this prospective, one-centre study, we assessed bone mineral and vitamin D alterations in 187 IBD patients (119 with Crohn's disease (CD) and 68 with ulcerative colitis (UC)). Results: While 81.3% of the patients had vitamin D deficiency, 14.2% of them had a severe deficiency. Elevated serum PTH concentrations were found in 14.9% of the patients. Only in 4.1% of cases was there an elevated level of a serum marker for bone formation (osteocalcin), whereas in 14.4% of cases, the bone resorption marker (CTX) was raised. The concentration of phosphate in urine was higher in the CD than in the UC group (51.20 vs. 31.25; p = 0.003). PTH was negatively associated with vitamin D level. Among the patients receiving corticosteroids, the CTX and CRP median levels were higher (0.49 vs. 0.38; p = 0.013 and 6.45 vs. 2.2; p = 0.029, respectively) compared with the group who did not receive them. Urine phosphate levels were lower (48.60 vs. 26.00; p = 0.005), as were osteocalcin (15.50 vs. 23.80; p < 0.001), and PTH (29.05 vs. 36.05; p = 0.018). Conclusions: Bone mineral alterations were common in patients with IBD, mostly in the CD patients. This may be associated with poor absorption, making CD patients vulnerable to changes in bone mineralization. Vitamin D supplementation remains crucial, especially when taking corticosteroids.

Diet as therapeutic intervention in Crohn's disease.

Diet plays an important role in the pathogenesis of inflammatory bowel disease. It has an impact on microbiome, host barrier, and immune response. Clinical studies indicate that various dietary interventions such as exclusive enteral nutrition and exclusion diets might be useful for induction of remission in mild to moderate Crohn's disease, but also for patients failing biological therapy. Current treatment strategies try to solve the problem of poor patient compliance due to the required strict dietary regime. The number of adverse events associated with the use of dietary alternatives is incomparable with the side effects of glucocorticosteroids or biological treatment, which makes them a tempting therapeutic option.

The effectiveness of microencapsulated sodium butyrate at reducing symptoms in patients with irritable bowel syndrome.

Aim: The aim of the study was to assess the effectiveness of a patented preparation of sodium butyrate in the triglyceride matrix at reducing clinical symptoms and improving quality of life in patients with irritable bowel syndrome (IBS). Material and methods: In this prospective multicenter clinical trial, we observed a total of 3000 non-hospitalized patients with confirmed IBS who were treated with sodium butyrate in a triglyceride matrix at a dosage of 150 mg twice a day for 12 weeks. The primary outcome was to evaluate the efficacy of sodium butyrate at reducing the severity of clinical symptoms and improving quality of life in patients with IBS. Results: A total of 2990 complete surveys were collected. A statistically significant improvement in severity of abdominal pain was noticed (p < 0.001). Moreover, flatulence, diarrhea, constipation, urgent pressure for bowel movements, nausea, and vomiting decreased significantly (p < 0.001). Most of the respondents (93.90%) declared that they would continue the therapy and 88.9% would recommend using sodium butyrate to other IBS patients. Conclusions: Sodium butyrate in the triglyceride matrix, as a postbiotic substance, may be effective in relieving the symptoms of IBS by modifying the intestinal microbiota.

Low-FODMAP Diet for the Management of Irritable Bowel Syndrome in Remission of IBD.

Approximately 30% of patients with quiescent inflammatory bowel disease (IBD) meet the diagnostic criteria for irritable bowel syndrome (IBS). The aim of this study was to evaluate the effectiveness of a low-FODMAP diet in patients who meet the diagnostic criteria for IBS whilst in IBD remission. A total of 200 patients in remission of IBD were included in the study. Sixty-five of these patients (32.5%) were diagnosed with IBS according to the R4DQ. On the patients who met the IBS diagnostic criteria, anthropometric measurements, laboratory tests and lactulose hydrogen breath tests were performed. A low-FODMAP diet was introduced for 6 weeks. Of the 59 patients with IBS diagnosed at baseline for whom data were collected at the end of follow-up, after the low-FODMAP intervention IBS-like symptoms were not present in 66.1% (n = 39) (95% CI (53.4%; 76.9%)). The difference between the two groups (with SIBO at baseline (33 of 48 patients) and without SIBO at baseline (6 of 11 patients)) in the low-FODMAP diet's effectiveness was not statistically significant (p = 0.586). The low-FODMAP diet improved the gut symptoms of flatulence and diarrhea. It had no effect on the occurrence of constipation. In IBD patients in remission who meet the IBS criteria, the dietary intervention of a low-FODMAP diet is effective for a reduction in IBS-like symptoms, regardless of the coexistence of bacterial overgrowth.

Gastrointestinal symptoms in patients with coronavirus disease 2019 (COVID-19) - friend or foe?

Introduction: Gastrointestinal (GI) symptoms can be considered as a manifestation of coronavirus disease 2019 (COVID-19). Aim: Our study analysed GI symptoms depending on their occurrence, and their possible causes and impact on the course of COVID-19. Material and methods: A retrospective, single-centre assessment of the frequency, risk factors, and impact of GI symptoms in 441 patients with COVID-19. Results: A statistically significant reduction in the length of stay (LOS) (15 days vs. 17 days; p = 0.04), intensive care unit admission (ICU) (16.9% vs. 26.8%; p = 0.02), and need for mechanical ventilation (14.1% vs. 23.4%; p = 0.02) in the group who had experienced GI symptoms before hospitalization was noticed. For comparison, patients who developed GI symptoms during hospitalization had statistically significantly longer LOS (21 days vs. 15 days; p = 0.0001), were more frequently admitted to the ICU (38.1% vs. 18.6%; p = 0.0003), and had a higher need for mechanical ventilation (32.7% vs. 16.2%; p < 0.001). Risk factors for GI symptoms during hospitalization in COVID-19 patients included age, Clostridioides difficile infection, and receiving certain treatment (antibiotics and lopinavir + ritonavir). Conclusions: The GI symptoms that developed before admission to hospital correlated with reduced severity of the course of COVID-19. However, in the group of patients who developed GI symptoms during hospitalization, attention should be paid to concomitant treatment. The use of antibiotics should be limited because they are associated with the deterioration of the course of COVID-19; one of the reasons might be changes in the intestinal microbiome.

Selected Aspects of Nutrition in the Prevention and Treatment of Inflammatory Bowel Disease.

Inflammatory bowel disease has become a global health problem at the turn of the 21st century. The pathogenesis of this disorder has not been fully explained. In addition to non-modifiable genetic factors, a number of modifiable factors such as diet or gut microbiota have been identified. In this paper, the authors focus on the role of nutrition in the prevention of inflammatory bowel disease as well as on the available options to induce disease remission by means of dietary interventions such as exclusive and partial enteral nutrition in Crohn's disease, the efficacy of which is reported to be comparable to that of steroid therapy. Diet is also important in patients with inflammatory bowel disease in the remission stage, during which some patients report irritable bowel disease-like symptoms. In these patients, the effectiveness of diets restricting the intake of oligo-, di-, monosaccharides, and polyols is reported.

Irritable bowel syndrome following COVID-19: an underestimated consequence of SARS-CoV-2 infection.

INTRODUCTION: Gastrointestinal (GI) symptoms are a common manifestation of COVID­19. OBJECTIVES: We aimed to investigate whether GI symptoms persist in patients previously infected with SARS­CoV­2 in the form of post­infection irritable bowel syndrome (PI­IBS). PATIENTS AND METHODS: A prospective, single­center evaluation of questions regarding IBS was conducted using the Rome IV Adult Diagnostic Questionnaire among 257 patients previously hospitalized for COVID­19. RESULTS: GI symptoms (abdominal pain with diarrhea or constipation) were reported at the following time points: at discharge from the hospital, and after 3 and 6 months of follow­up. GI symptoms not meeting the full Rome IV diagnostic criteria for IBS due to too short symptom duration were reported by 28 individuals (10.6%) at hospital discharge, 58 (22.3%) after 3 months, and 70 (26.9%) after 6 months. The full Rome IV criteria for IBS were not met at discharge by any of the participants, but they were met after 3 and 6 months of follow­up in 14 (5.4%) and 15 individuals (5.8%), respectively. CONCLUSION: Persistent GI symptoms following COVID­19 are frequent and deserve significant and growing attention of gastroenterologists and other health care practitioners. The Rome IV criteria may be too strict to address the full spectrum of GI symptoms following COVID­19.

Preparation for endoscopic examinations in patients with diabetes and hypoglycaemia.

Endoscopy is a procedure used for diagnostic and therapeutic purposes, which requires proper preparation. Patients with diabetes mellitus are particularly predisposed to inadequate cleansing for endoscopy due to slowing bowel movements, dietary preparation restrictions, glucose reduction, and the resulting symptoms of hypoglycaemia. So far, no comprehensive guidelines of preparation for endoscopic examinations for patients with these metabolic disorders have been developed. Considering the number of patients who may be subjected to colonoscopy and the possible effects of suboptimal preparation for the examination, the lack of such recommendations seems to be a significant gap in the healthcare system. The article reviews the literature on the above topic.

The Use of Virtual Reality to Reduce Stress among Inflammatory Bowel Disease Patients Treated with Vedolizumab.

(1) Background: The use of virtual reality (VR) in improving patient comfort related to medical procedures in oncology patients raised the question of whether similar benefits could be obtained by patients with inflammatory bowel disease (IBD). (2) Methods: In this prospective, randomized, controlled, single-center clinical trial, a total of 90 patients with IBD treated with vedolizumab were enrolled and randomized in a 1:1 allocation to either the VR immersion group or the routine-treated group. The primary outcome was to evaluate whether VR could decrease stress and anxiety related to a medical procedure. The secondary outcome was to assess the safety of the VR. (3) Results: A statistically significant improvement in well-being and psychological comfort (p = 0.046), feeling of relaxation (p = 0.046), sense of influence on the treatment process (p < 0.001), improved perception of the way the drug works (p < 0.001), improved positive attitude while waiting for the next administration of the drug (p = 0.026), and increased motivation for treatment (p = 0.026) was noticed in the intervention group. There were no statistically significant differences in the incidence of complications in the intervention and control groups. (4) Conclusions: The use of VR had a positive effect on the reduction of stress associated with vedolizumab treatment and could improve compliance.

Management of anaemia in patients with inflammatory bowel disease - results of a questionnaire among Polish healthcare professionals.

INTRODUCTION: Anaemia is the most common systemic and extraintestinal complication of inflammatory bowel disease (IBD). Its impact on quality of life is significant; hence, it is important for healthcare professionals to manage it correctly. AIM: To assess the knowledge among doctors about the diagnostics and treatment of anaemia in IBD patients. MATERIAL AND METHODS: The questionnaire survey was conducted among 169 doctors of different specialties. Eighty-seven (51.5%) of the respondents were gastroenterologists. RESULTS: 97.7% (84) of gastroenterologists and 92.6% (75) of all responders replied that all IBD patients should be monitored for anaemia (p = 0.266); however, only one-third of gastroenterologists knew the exact haemoglobin cut-off level in men with Crohn's disease. The necessity of monitoring vitamin B12 was indicated by 53.7% (36) of gastroenterologists and by 24.1 % (13) of other specialists (p = 0.002). Nine percent (6) of gastrologists and 3.7% (2) of other specialists screened for folic acid (p = 0.0431). 13.1% (11) of gastroenterologists and 35% (28) of other specialists frequently used iv iron (p = 0.003). 44.1% (26) of gastroenterologists and 52% (26) of other specialists administered between 1000 mg and 1500 mg of iv iron during hospitalization. Only 11.9 % (7) of GI-specialists and 2% (1) of non-GI-specialists administered total doses over 1500 mg (p = 0.155). 71% (62) of gastroenterologists and 73% (60) of all physicians did not observe any adverse events of iv iron. CONCLUSIONS: Although the diagnostic approach to anaemia in IBD patients varies among respondents, knowledge of guidelines was slightly better among GI-professionals then among other doctors.

Clostridioides difficile infection in coronavirus disease 2019 (COVID-19): an underestimated problem?

INTRODUCTION: The use of antibiotics and possibility of microbiota disruption during the coronavirus disease 2019 (COVID­19) pandemic have raised questions about the incidence of Clostridioides difficile infection (CDI). OBJECTIVES: This study aimed to assess the frequency of and risk factors for CDI in patients with COVID­19. PATIENTS AND METHODS: We conducted a retrospective, single­center evaluation study on the frequency of and risk factors for CDI in patients with COVID­19 and in the prepandemic era. The analysis included 441 patients with severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) infection and 2961 pa­ tients hospitalized before the pandemic. RESULTS: A significant increase in the incidence of CDI was noted during the COVID­19 pandemic compared with the prepandemic period: 10.9% versus 2.6%, P <0.001. Risk factors for CDI in patients with COVID­19 included: age, length of hospital stay, occurrence of diarrhea during hospitalization, use of antibiotics other than azithromycin, and coexistence of nervous system disease or chronic kidney disease-all of these factos had a weak association with CDI development. The multivariable logistic regression model indicated other unassessed variables that had an impact on the CDI incidence rate. CONCLUSIONS: We observed a higher incidence of CDI in patients with COVID­19. Antibiotic therapy was a relevant risk factor for CDI, although its effect was weak. Other drugs used during the pandemic were not found to have an impact on disease development. Possible causes of CDI may include fecal microbiota disruption by SARS­CoV­2 infection, but further research is needed to validate this hypothesis.
