Inflammatory bowel disease evolution in the past two decades: a chronological multinational study.

Background: The multifactorial nature of inflammatory bowel disease (IBD), which manifests differently in individuals creates a need for a better understanding of the behaviour and pattern of the disease due to environmental factors. The current study aimed to study the changes in IBD behaviour, presentation, and characteristics in patients over the past two decades with a goal of improving patients' diagnosis, management and outcomes. Methods: During a 6-month period (1/02/2022-30/07/2022), the information of patients with IBD who attended IBD outpatient clinics of 11 referral centre's in six countries was collected, and based on the first time of diagnosis with IBD, they were allocated as group A (those who were diagnosed more than 15 years ago), group B (those who were diagnosed with IBD between 5 and 15 years ago) and group C (IBD cases who diagnosed in recent 5 years). Then the most prevalent subtypes and characters of the disease are evaluated and compared to make clear if the presenting pattern and behaviour of the disease has changed in the last 2 decades. Findings: Overall 1430 patients with IBD including 1207 patients with ulcerative colitis (UC) (84.5%) and 205 patients with Crohn's disease (CD; 14.3%) included. Mean age of participants at the first time of diagnosis with IBD was 30 years. The extra-intestinal involvement of IBD in groups A and B was more prevalent in comparison with group C. Most of those in groups A & B had academic education but in group C, the most prevalent educational status was high school or diploma (P = 0.012). In contrast to groups A and B, the relative prevalence of medium socioeconomic level in group C had decreased (65%). Relative prevalence of UC subtypes was similar among groups A and B (extensive colitis as most prevalent) but in group C, the most prevalent subtype is left side colitis (38.17%). The most prevalent subtype of CD in groups A and B was ileocolic involvement while in group C, upper GI involvement is significantly increased. The rate of food sensitivity among groups A and B was more than group C (P = 0.00001). The relative prevalence of patients with no flare has increased with a steady slope (P < 0.00001). Relative prevalence of presenting symptoms among patients with UC in group C differs and nowadays the rate abdominal pain (70.7%) and bloating (43.9%) have increased and frequency of diarrhoea (67.4%) has decreased. Interpretation: In the recent 5 years, the pattern of UC presentation has changed. The rate of upper GI involvement in CD and relative prevalence of patients with no disease flare increased and the rate of extra intestinal involvement decreased. Funding: None.

Levofloxacin+Tetracycline Quadruple Regimen for Eradication of Helicobacter pylori: A Multicenter Multinational Randomized Controlled Trial.

Background: The ideal combination regimen for Helicobacter pylori (HP) eradication has not yet been determined and the success rate of HP eradication has been extensively reduced worldwide due to increasing antibiotic resistance. So this multinational multi-center randomized controlled trial was designed to evaluate the efficacy of tetracycline +levofloxacin for HP eradication. Methods: During a 6-month period, all of the cases with HP infection in eight referral tertiary centers of three countries were included and randomly allocated to receive either tetracycline + levofloxacin or clarithromycin plus amoxicillin quadruple regimen for two weeks. For all of the participants, pantoprazole was continued for 4 more weeks and after one to two weeks of off-therapy, they underwent urea breath test C13 to prove eradication. Results: Overall 788 patients were included (358 male (45.4%), average age 44.2 years). They were diagnosed as having non-ulcer dyspepsia (516 cases, 65.5%), peptic ulcer disease (PUD) (234 cases, 29.69%), and intestinal metaplasia (38 cases, 4.8%). Racially 63.1% were Caucasian, 14.5% Arab, 15.6% African, and 6.1% Asian. The participants were randomly allocated to groups A and B to receive either tetracycline + levofloxacin or clarithromycin. Among groups A and B in intention to treat (ITT) and per protocol (PP) analysis, 75.2% & 82.1% (285 cases) and 67.5% & 70.1% (276 cases) of participants achieved eradication, respectively (P = 0.0001). The complete compliance rate in groups A and B were 84.4% and 83.6%, respectively. During the study, 33.5% of the participants in group A (127 cases) reported side effects while the complication rate among group B was 27.9% (114 cases, P = 0.041). The most common complaints among groups A and B were nausea and vomiting (12.6% & 9.3%) and abdominal pain (4.48% & 2.68%), respectively. The rate of severe complications that caused discontinuation of medication in groups A and B were 2.1% and 1.46%, respectively (P = 679). In subgroup analysis, the eradication rates of tetracycline+levofloxacin among patients with non-ulcer dyspepsia, PUD, and intestinal metaplasia were 79.4%, 88.1%, and 73.9%, respectively. These figures in group B (clarithromycin base) were 71.3%, 67.6%, and 61.5% respectively (P = 0.0001, 0.0001, and 0.043). Conclusion: Overall, the combination of tetracycline+levofloxacin is more efficient for HP eradication in comparison with clarithromycin+amoxicillin despite more complication rate. In areas with a high rate of resistance to clarithromycin, this therapeutic regimen could be an ideal choice for HP eradication, especially among those who were diagnosed with PUD.

Dormia Basket versus Extraction Balloon in Proximally Migrated Biliary Stents.

Objectives: To compare balloon extraction versus Dormia basket in the retrieval of proximally migrated stent. Method: The prospective study was conducted at Tanta University Hospital and Kafrelsheikh University Hospital, Egypt, from December 2019 to December 2020, and comprised adult patients of either gender who presented with proximally migrated biliary plastic stent who were evaluated with respect to risk factor for migration. The difference in efficacy of and Dormia basket group A and balloon extraction group B was evaluated. Data was analysed using SPSS 21. RESULTS: Of the 80 patients, 43(53.8%) were males and 37(46.3%) were females. The overall mean age was 55.7±14.2 years. Group A had 40(50%) patients; 21(52.2%) males and 19(47.5%) females with mean age 56.9±14.1 years. Group B had 40(50%) patients; 22(55%) males and 18(45%) females with mean age 54.6±14.5 years. (p>0.05). Change-over to the other method was done in 15(37.5%) patients of group A and in 8(20%) of group B (p=0.084). Mean time of the procedure was 57.4±21.7min in group A and 37.5±21.6min in group B (p≤0.001). Complications occurred in 3(7.5%) group A patients and 2(5.0%) group B patients (p=1.0). CONCLUSIONS: Balloon extraction was found to be more successful than Dormia basket in the extraction of proximally migrated stent.

Ascitic Fluid Calprotectin And Ratio Of Calprotectin To Total Protein In Spontaneous Bacterial Peritonitis.

Objectives: To evaluate the diagnostic and prognostic role of ascitic fluid calprotectin and its ratio to total protein in spontaneous bacterial peritonitis cases. Method: The prospective study was conducted at Kafrelsheikh University Hospital, Egypt, from November 2019 to December 2020, and comprised cirrhotic patients of either gender with ascites. Diagnostic abdominal paracentesis was performed for all patients and ascetic fluid calprotectin was measured. Patients were followed for development of spontaneous bacterial peritonitis or mortality. Data was analysed using SPSS 20. RESULTS: Of the 90 patients, 61(67.7%) were males and 29(32.2%) were females. There were 67(74.4%) patients with spontaneous bacterial peritonitis; 48(71.6%) males and 19(28.3%) females with mean age 60.42±8.3 years. The remaining 23(25.5%) did not have spontaneous bacterial peritonitis; 13(56.5%) males and 10(43.4%) females with mean age 59.7±7.4 years. The patients had significantly higher calprotectin, and calprotectin/total protein ratio (p<0.05). Logistic regression identified ascitic fluid calprotectin as a significant predictor of mortality (p=0.05). The non-survivors had significantly higher ascitic fluid calprotectin and calprotectin/total protein ratio compared to the survivors (p<0.05). CONCLUSIONS: Ascites calprotectin level and itsratio to total protein wasfound to be accurate diagnostic and predictive biomarkers for spontaneous bacterial peritonitis.

Is Endoscopy Mandatory In Cases Mimicking Acute Pancreatitis?

Objectives: To detect the utility of nonspecific rising of pancreatic enzymes in patients with stomach discomfort, and to explore the possibility of hyperamylasemia as a differential diagnosis. Method: The cross-sectional study was conducted from April 2020 to April 2021 at two large tertiary care centres in Kafrelsheikh and Zagazig governorates in northern Egypt, and comprised patients complaining of dull aching abdominal pain. They were classified into two groups. Patients with nonspecific rise in pancreatic enzymes less than threefold in the absence of acute pancreatitis were in group I, while those having abdominal pain without rise in pancreatic enzymes were in group II. All patients were subjected to detailed history and clinical examination followed by laboratory assessment, imaging studies and upper endoscopy. Data was analysed using SPSS 20. RESULTS: Of the 270 patients, 170(63%) were in group I; 120(70.5%) males and 50(29.5%) females with mean age 51±6.58 years, There were 100(37%) patientsin group II; 65(65%) males and 35(35%) females with mean age 53±8.96 years (p>0.05). Amylase, lipase, serum glutamic-oxaloacetic transaminase, serum glutamic-pyruvic transaminase, Creactive protein and helicobacter pylori values were significantly different between the groups (p<0.05). CONCLUSIONS: Elevation of pancreatic enzymes with a level less than three-fold in patients with abdominal pain reflected mucosal injury of the gastrointestinal tract and may raise the necessity for diagnostic upper endoscopy.

Relation Between Interleukin-6, Interleukin-10 And Interleukin-2 Receptor And Mortality In Severely Ill COVID-19 Patients.

Objectives: To investigate the relation involving soluble interleukin-2 receptor, interleukin-6 and interleukin-10 in hospitalised patients with severe coronavirus disease-2019 infection. Method: This single-centre cohort study was conducted at the Kafrelshiekh University Hospital, Egypt, from January to June 2022, and included all patients of either gender who were hospitalised with severe infection with the coronavirus disease-2019 isolation ward. Chemiluminescence immunoassay method was used to measure levels of procalcitonin, ferritin, soluble interleukin-2 receptor, interleukin-6 and interleukin-10. Data was analysed using SPSS version. 25. RESULTS: Of the 250 patients with median age 57.5 years (interquartile range: 45.8-66.0 years), 147(59%) were males and 103(41%) were females. Of them, 102(40.8%) patients died; 68(66.7%) males, 34(33.3%) females, median age 60.0 years (interquartile range: 48.8-70.0). Among the 148(59.2%) survivors, 79(53.4%) were males and 69(46.6%) were females, while the overall median age was 55.0 years (interquartile range: 41.5-65.8 years). The survivors had significantly lower levels of soluble interleukin-2 receptor, interleukin-6 and interleukin-10 (p<0.001). Correlation analysisidentified significant positive correlation between IL-2R, IL-6 and IL-10 levels and almost all the inflammatory and coagulation parameters, including C-reactive protein, lactate dehydrogenase, procalcitonin, ferritin, D-dimer and fibrinogen (p<0.05). CONCLUSIONS: Elevated levels of soluble interleukin-2 receptor, interleukin-6 and interleukin-10 were found to be associated with greater risk of mortality in coronavirus disease-2019 patients.

Do You Have To Evaluate The Heart Of The Cirrhotic Patients?

Objectives: To identify patients with occult cardiac dysfunction and itsrelationship with the severity of liver impairment. Method: This is a Judgment (Purposive) Sampling, cross-sectionalstudy that was conducted at Kafrelsheikh University Hospital, Egypt, from November 2019 to December 2020, and comprised adult patients of either gender with liver cirrhosis. After detailed history, a clinical examination, pathological assessment and cardiac evaluation based on electrocardiogram and echocardiography, the patients were divided into three groups. Patients who had dyspnoea or cyanosis were in group A, those who did not have dyspnoea or cyanosis but had electrocardiogram and echocardiography abnormalities were in group B, and patients who did not have dyspnoea, cyanosis or electrocardiogram and echocardiography abnormalities were in group C. The severity of the liver disease was evaluated using Child-Pugh and Model of End Liver Disease scores. Data was analysed using SPSS 20. RESULTS: Of the 300 patients, 153(51%) were males and 147(49%) were females. The overall mean age was 55.1±5.1 years(range: 20-60 years). There were 58(19.33%) patientsin group A, 108(36%) in group B and 134(44.66%) in group C. Group A patientsshowed higher Child-Pugh and Model of End Liver Disease scoresthan the other groups(p<0.05). Child-Pugh score >6 and Model of End Liver Disease score >37 yielded the best accuracy for detecting cardiac abnormalities in group B (p<0.05). CONCLUSIONS: There were significant cardiac changes in cirrhotic patients.

Value Of Abdominal Pressure By Using Abdominal Belt In Facilitating Colonoscopic Procedure In Egyptian Patients.

Objectives: To evaluate the role of applying abdominal pressure using abdominal belt in overall improvement in the practice of colonoscopy. Method: The randomised, single-blind case-control study was conducted from March 2020 to March 2021 at Kafrelsheikh University Hospital, Cairo, Egypt, and comprised patients of either gender aged 30-70 years who underwent elective colonoscopy. The patients were randomised into belly belt group A and control group B. The endoscopist was blinded to the group assignment. Time needed to reach the caecum, requirement for changing the position, dosage of anaesthetic agents, completion of endoscopy, ileal intubation, post-procedure pain and abdominal distension were noted and compared between the groups. Data was analysed using SPSS 24. RESULTS: Of the 160 patients, 80(50%) were in each of the two groups. There were 38 (47.5%) males and 43 (52.5%) (females) in group A with mean age 55.8±4.1 years. In group B, there were 40(50%) males and as many females with mean age 55.4±3.4 years. Group A had significantly better overall outcomesthan group B (p<0.05) except procedure complications (p=0.526). CONCLUSIONS: Abdominal belt wasfound to be an effective and simple method to improve the practice of colonoscopy.

Sonographic gallbladder wall thickness measurement and the prediction of esophageal varices among cirrhotics.

Acute variceal bleeding in patients with liver cirrhosis and portal hypertension (PHT) is the most serious emergency complication among those patients and could have catastrophic outcomes if not timely managed. Early screening by esophago-gastro-duodenoscopy (EGD) for the presence of esophageal varices (EVs) is currently recommended by the practice guidelines for all cirrhotic patients. Meanwhile, EGD is not readily accepted or preferred by many patients. The literature is rich in studies to investigate and validate non-invasive markers of EVs prediction aiming at reducing the unneeded endoscopic procedures. Gallbladder (GB) wall thickness (GBWT) measurement has been found promising in many published research articles. We aim to highlight the validity of sonographic GBWT measurement in the prediction of EVs based on the available evidence. We searched databases including Cochrane library, PubMed, Web of Science and many others for relevant articles. GBWT is associated with the presence of EVs in cirrhotic patients with PHT of different etiologies. The cut-off of GBWT that can predict the presence of EVs varied in the literature and ranges from 3.1 mm to 4.35 mm with variable sensitivities of 46%-90.9% and lower cut-offs in viral cirrhosis compared to non-viral, however GBWT > 4 mm in many studies is associated with acceptable sensitivity up to 90%. Furthermore, a relation was also noticed with the degree of varices and portal hypertensive gastropathy. Among cirrhotics, GBWT > 3.5 mm predicts the presence of advanced (grade III-IV) EVs with a sensitivity of 45%, the sensitivity increased to 92% when a cut-off ≥ 3.95 mm was used in another cohort. Analysis of these results should carefully be revised in the context of ascites, hypoalbuminemia and other intrinsic GB diseases among cirrhotic patients. The sensitivity for prediction of EVs improved upon combining GBWT measurement with other non-invasive predictors, e.g., platelets/GBWT.

Post-cholecystectomy iatrogenic bile duct injuries: Emerging role for endoscopic management.

Post-cholecystectomy iatrogenic bile duct injuries (IBDIs), are not uncommon and although the frequency of IBDIs vary across the literature, the rates following the procedure of laparoscopic cholecystectomy are much higher than open cholecystectomy. These injuries caries a great burden on the patients, physicians and the health care systems and sometime are life-threatening. IBDIs are associated with different manifestations that are not limited to abdominal pain, bile leaks from the surgical drains, peritonitis with fever and sometimes jaundice. Such injuries if not witnessed during the surgery, can be diagnosed by combining clinical manifestations, biochemical tests and imaging techniques. Among such techniques abdominal US is usually the first choice while Magnetic Resonance Cholangio-Pancreatography seems the most appropriate. Surgical approach was the ideal approach for such cases, however the introduction of Endoscopic Retrograde Cholangio-Pancreatography (ERCP) was a paradigm shift in the management of such injuries due to accepted success rates, lower cost and lower rates of associated morbidity and mortality. However, the literature lacks consensus for the optimal timing of ERCP intervention in the management of IBDIs. ERCP management of IBDIs can be tailored according to the nature of the underlying injury. For the subgroup of patients with complete bile duct ligation and lost ductal continuity, transfer to surgery is indicated without delay. Those patients will not benefit from endoscopy and hence should not do unnecessary ERCP. For low-flow leaks e.g. gallbladder bed leaks, conservative management for 1-2 wk prior to ERCP is advised, in contrary to high-flow leaks e.g. cystic duct leaks and stricture lesions in whom early ERCP is encouraged. Sphincterotomy plus stenting is the ideal management line for cases of IBDIs. Interventional radiologic techniques are promising options especially for cases of failed endoscopic repair and also for cases with altered anatomy. Future studies will solve many unsolved issues in the management of IBDIs.

Effect of Helicobacter pylori eradication on metabolic profile: an international, multicenter, case-control study.

BACKGROUND: As a gram-negative and microaerophilic bacterium, Helicobacter pylori (HP) is the main cause of chronic gastritis. Therefore, considering the high prevalence of HP infection worldwide, as well as the increasing prevalence of metabolic disorders, the present study aimed to investigate the relationship between HP infection eradication and metabolic profile. METHODS: This prospective case-control study was performed on patients with HP infection whom referred to 7 medical centers in 3 countries (Iran, Egypt, and Vietnam) in 2020-2021. The metabolic profile of all of the participants evaluated before starting of treatment for HP eradication and 3 months after the treatment. Then changes of metabolic profile compared between those with successful HP eradication (group A) and subjects who failed to eradicate (group B). RESULTS: Overall, 199 patients, including 93 male (46.7%) with the mean age of 44.5 years (18-93 years) included. Based on response to treatment, the participants allocate into group A (those who respond to HP eradication): 164 cases (82.42%); or group B as those who failed to achieve eradication (35 cases, 17.58%). Racially 86.9% of participants were Caucasian and 89% diagnosed as non-ulcer dyspepsia (NUD). The most prevalent comorbidity include hypertension (11.5%) and hyperlipidemia (10%) which were more prevalent in group B (P = 0.002). Three months after therapy, average weight of participants among those who achieved eradication (group A) decreased from 73.1 to 71.4 kg (P = 0.01), but in comparison with group B, was non-significant (P = 0.171). The BMI of patients before and after treatment did not show any significant differences. The biochemical parameters of patients before and after treatment were not significantly different regardless of treatment success (P > 0.05). The levels of total cholesterol and VLDL cholesterol after treatment were not significantly different from baseline values in two groups. HDL and LDL cholesterol levels before and after treatment in the resistant group were significantly higher than the responding group. Average serum TG level decreased significantly after treatment in the group A (P < 0.0001), in contrast to the resistant group (P = 0.356). The liver transaminases (AST and ALT) before and after treatment were not significantly different between the two groups (P > 0.05). The results of logistic regression showed that the eradication of infection has no significant affect any of the metabolic profile parameters. CONCLUSION: HP infection treatment in individuals without significant metabolic disorders does not affect metabolic parameters up to 3 months after eradication. HP eradication among subjects with several comorbidities mandates eradication protocol intensification to avoid treatment failure.

Cisteína oral N-Acetyl versus indometacina retal para prevenção de pancreatite pós-CPRE: um ensaio controlado randomizado multinacional multicêntrico / Oral n-acetyl cysteine versus rectal indomethacin for prevention of post ercp pancreatitis: a multicenter multinational randomized controlled trial

ABSTRACT Background This multicenter multinational RCT designed to compare the efficacy of suppository indomethacin and NAC for prevention of PEP. Methods: During a 6-month period, all of the ERCP cases in seven referral centers were randomly assigned to receive either 1200 mg oral NAC, indomethacin suppository 100 mg, 1200 mg oral NAC plus indomethacin suppository 100 mg or placebo 2 hours before ERCP. The primary outcomes were the rate and severity of any PEP. Results: A total of 432 patients included (41.4% male). They were originally citizens of 6 countries (60.87% Caucasian). They were randomly allocated to receive either NAC (group A, 84 cases), rectal indomethacin (group B, 138 cases), NAC + rectal indomethacin (group C, 115 cases) or placebo (group D, 95 cases). The rate of PEP in groups A, B and C in comparison with placebo were 10.7%, 17.4%, 7.8% vs 20% (P=0.08, 0.614 & 0.01 respectively). The NNT for NAC, indomethacin and NAC + indomethacin was 11, 38 and 8 respectively. Conclusion: Oral NAC is more effective than rectal indomethacin when compared to placebo for prevention of PEP and the combination of NAC and Indomethacin had the lowest incidence of PEP and may have synergistic effect in preventing of PEP (IRCT20201222049798N1; 29/12/2020).

Clinical and genetic characterization of familial Mediterranean fever among a cohort of Egyptian patients.

Introduction: Familial Mediterranean fever (FMF) is an autosomal recessive disease with an autoinflammatory nature. It affects mainly Turkish, Armenian, Arab, and Jewish people. The clinical presentation and the development of complication as amyloidosis. Early diagnosis and predilection of disease severity according to gene mutation facilitates adequate treatment and disease control. Aim: To our knowledge, few studies were done to evaluate FMF in lower Egypt. Material and methods: This is a prospective study that was carried out at Kafrelsheikh University Hospital Outpatient Clinic between March 2019 and February 2020. We recruited all patients who came to our outpatient clinic with symptoms suggestive of FMF (recurrent attacks of abdominal pain and fever), and diagnosis of FMF was confirmed by gene study. One hundred and nine patients were included; however, 9 patients refused to participate in the study, so final analysis was done for 100 patients only. Patients also underwent abdominal ultrasound examination for measurement of the spleen longitudinal diameter. Results: E148Q mutant allele was the most encountered mutation in our studied patients at Kafrelsheikh, with a frequency of 31%; the number of attacks was greater in patients with positive family history and in homozygous patients. Most patients required a dose between 1.5 and 3 mg/day. Conclusions: Patients with positive family history and those with homozygous mutation have more attacks with greater severity and higher amyloid deposition. E148Q mutant allele was the most commonly encountered in the studied patients, with a frequency of 31%, followed by M6801 (G/A), which was associated with the highest amyloid A level.

IS DAIRY FOODS RESTRICTION MANDATORY FOR INFLAMMATORY BOWEL DISEASE PATIENTS: A MULTINATIONAL CROSS-SECTIONAL STUDY.

BACKGROUND: The role of dairy foods in inflammatory bowel disease (IBD) has been controversial and it is debatable if patients with IBD should avoid milk and dairy products or not, as well as the relationship between these foods and symptoms among those population. OBJECTIVE: This multi centric cross-sectional study designed to evaluate if it is really necessary to deprive IBD patients from consumption of dairy foods. METHODS: A multicenter study with 12 gastroenterology referral centers in four countries was designed to evaluate gastrointestinal (GI) symptoms after consumption of dairy foods from all outpatients with IBD during 6 months and to compare patients treated at the same centers without IBD (non IBD cases). RESULTS: Overall 1888 cases included (872 IBD patients and 1016 non IBD cases). 56.6% of participants were female with average age of 40.1 years. Racially 79.8% participants were Caucasians and originally they were citizens of 10 countries. Relative prevalence of IBD was higher in Africans and Indians and the most frequent prevalence of dairy foods intolerance was seen in Asians. Among IBD patients, 571 cases diagnosed as ulcerative colitis and 189 participants as Crohn's disease. Average duration of diagnosis as IBD was 6.8 years (from 2 months to 35 years). The most prevalent GI symptoms after consumption of all the dairy foods were bloating and abdominal pain. Totally, intolerance of dairy foods and lactase deficiency was more prevalent among IBD patients in comparison with non IBD cases (65.5% vs 46.1%, P=0.0001). But the rate of GI complains among IBD patients who had not any family history of lactase deficiency, history of food sensitivity or both were 59.91%, 52.87% & 50.33% respectively and similar to non IBD cases (P=0.68, 0.98 & 0.99 respectively). CONCLUSION: The rate of dairy foods intolerance among IBD patients without family history of lactase deficiency or history of food sensitivity is similar to non IBD cases and probably there is no reason to deprive them from this important source of dietary calcium, vitamin D and other nutrients.

But the rate of GI complains among IBD patients who had not any family history of lactase deficiency, history of food sensitivity or both were 59.91%, 52.87% & 50.33% respectively and similar to non IBD cases (P=0.68, 0.98 & 0.99 respectively). Conclusion: The rate of dairy foods intolerance among IBD patients without family history of lactase deficiency or history of food sensitivity is similar to non IBD cases and probably there is no reason to deprive them from this important source of dietary calcium, vitamin D and other nutrients.

RESUMO Contexto: O papel dos alimentos lácteos na doença inflamatória intestinal (DII) tem sido controverso e é discutível se os pacientes com DII devem ou não evitar leite e laticínios, bem como a relação entre esses alimentos e sintomas nesta população. Objetivo: Estudo transversal multicêntrico foi projetado para avaliar se é realmente necessário privar os pacientes com DII do consumo desta classe de alimentos. Métodos: Um estudo multicêntrico com 12 centros de referência em gastroenterologia de quatro países foi projetado para avaliar sintomas gastrointestinais após o consumo de alimentos lácteos em todos os ambulatórios de DII durante seis meses e comparar pacientes tratados nos mesmos centros sem DII. Resultados: No total, foram incluídos 1888 casos (872 pacientes com DII e 1016 casos sem DII. 56,6% dos participantes eram do sexo feminino com idade média de 40,1 anos. 79,8% dos participantes eram caucasianos e originalmente eram cidadãos de 10 países. A prevalência relativa de DII foi maior em africanos e indianos e a prevalência mais frequente de intolerância a alimentos lácteos observada nos asiáticos. Entre os pacientes com DII, 571 casos foram diagnosticados como colite ulcerativa e 189 participantes como doença de Crohn. A duração média do diagnóstico como DII foi de 6,8 anos (de 2 meses a 35 anos). Os sintomas de gastrointestinais mais prevalentes após o consumo de todos os alimentos lácteos foram inchaço e dor abdominal. No total, a intolerância aos alimentos lácteos e a deficiência de lactase foi mais prevalente entre os pacientes com DII em comparação com os casos sem DII (65,5% vs 46,1%, P=0,0001). A taxa de queixas gastrointestinais entre os pacientes com DII que não tinham histórico familiar de deficiência de lactase, histórico de sensibilidade alimentar ou ambos foram de 59,91%, 52,87% e 50,33% respectivamente e semelhantes aos casos sem DII (P=0,68, 0,98 e 0,99, respectivamente). Conclusão: A taxa de intolerância de alimentos lácteos entre pacientes com DII sem histórico familiar de deficiência de lactase ou histórico de sensibilidade alimentar é semelhante aos casos sem DII e provavelmente não há razão para privá-los dessa importante fonte de cálcio dietético, vitamina D e outros nutrientes.

Endoscopic resection of superficial bowel neoplasia: The unmet needs in the Egyptian practice.

BACKGROUND: Management of superficial bowel neoplasia (SBN) in early stages is associated with better outcomes. The last few decades experienced a paradigm shift in the management of SBN with the introduction of advanced endoscopic resection techniques (ERTs). However, there are no clear data about the aspects of ERTs in Egypt despite the growing gastroenterology practice. AIM: To investigate the knowledge, attitude, and practice of ERTs toward management of SBN among Egyptian practitioners and the suitability of the endoscopy units' infrastructures toward these techniques. METHODS: An online 2-pages questionnaire was used. The first page comprised demographic data, and questions for all physicians, about the knowledge (11 questions) of and attitude (5 questions) toward ERTs as a therapeutic option for SBN. The second page investigated the practice of ERTs by endoscopists (6 questions) and the infrastructures of their endoscopy units (14 questions). The survey was disseminated through July 2021 and the data were collected in an excel sheet and later analyzed anonymously. RESULTS: The complete responses were 833/2300 (36.2%). The majority of the participants were males (n = 560, 67.2%), middle-aged (n = 366, 43.9%), consultants (n = 464, 55.7%), gastroenterologists (n = 678, 81.4%), spending ≥ 15 years in practice (n = 368, 44.2%), and were working in university hospitals (n = 569, 68.3%). The majority correctly identified the definition of SBN (88.4%) and the terms polypectomy, endoscopic mucosal resection (EMR), and endoscopic submucosal dissection (ESD) (92.1%, 90.2%, and 89.1% respectively). However, 26.9%, 43.2% and 49.5% did not recognize the clear indication of polypectomy, EMR, and ESD respectively. Although 68.1% of physicians are convinced about the ERTs for management of SBN; only 8.9% referred all candidate cases for ERTs. About 76.5% of endoscopists had formal training in the basic polypectomy techniques while formal training for EMR and ESD was encountered only in 31.9% and 7.2% respectively. About 71.6% and 88.4% of endoscopists did not perform EMR or ESD in the last one year. Consequently, the complication rate reported by endoscopists was limited to 18.1% (n = 103) of endoscopists. Only 25.8% of endoscopists feel confident in the management of ERTs-related complications and a half (49.9%) were not sure about their competency. Regarding the endoscopy units' infrastructures, only 4.2% of the centers had their endoscopes 100% armed with optical enhancements and 54.4% considered their institutions ready for managing ERTs-related complications. Only 18.3% (n = 104) of endoscopists treated their complicated cases surgically because the most frequent ERTs-related complications were procedural bleeding (26.7%), and perforations (17%). CONCLUSION: A significant deficiency was reported in the knowledge and attitude of Egyptian practitioners caring for patients with SBN toward ERTs. The lack of trained endoscopists in both EMR and ESD in part is due to unsuitable infrastructures of many endoscopy units.

Can fecal calprotectin reflect your colonic status?

Background: Organic colonic manifestation may be difficult to be differentiated from functional one. Inflammatory bowel disease (IBD) is a common chronic inflammatory and destructive disease of the bowel wall. Chronic inflammation is associated with ulcerations, strictures, perforations, and it is a risk factor for dysplasia and cancer. To reduce these long-standing complications, IBD patients are in a continuous need for early diagnosis1. Markers, such as erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP), fecal calprotectin (FC) have been widely used as noninvasive parameters for IBD monitoring. We aimed, in this current study, to evaluate the value of fecal calprotectin and other noninvasive biomarkers in predicting abnormal histologic findings in patients undergoing colonoscopy.in addition to determine the cutoff value which predict IBD2. Methods: The present prospective study included 160 patients with complaint of colicky abdominal pain with frequent diarrhea associated with mucous and infrequent bleeding per rectum for more than 6 months. They presented partial improvement with medication and recurrence once stopping the treatment These patients had been recently diagnosed with IBD at many primary healthcare centers covering the areas of the Kafrelsheikh and Zagazik governorate in the North of Egyptian Nile delta. After complete history, clinical examination, and laboratory investigation, they were referred to the IBD clinic at Kafrelsheikh University Hospital for assessment and ileocolonoscopy with biopsies. Results: There was a wide spectrum of age of the studied patients, with mean age 40.12±7.88 (minimum 18 and maximum 56 years). Regarding gender, males represented 87.5% of the studied patients. Forty percent of the patients with colonic manifestation were smokers, 57% preferred a spicy diet, and the majority had low educational level (77.5%). Forty percent had obvious blood in stool, 55% had occult blood, and raised ESR CRP occurred in 32.5% and 50%, respectively. Fecal calprotectin cutoff was>159, with sensitivity 92.8% and specificity 97.5%. Conclusions: Biomarkers (FC, ESR, CRP) can be used as noninvasive parameters for the early diagnosis and prediction of organic colonic disease. Fecal calprotectin in the IBD group revealed significant area under the curve (AUC) values and cutoff> 159, with sensitivity 92.8% and specificity 97.5%. (AU)

The promising role of CCL2 as a noninvasive marker for nonalcoholic steatohepatitis diagnosis in Egyptian populations.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a common liver problem, including both nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH). In this study, we investigated the role of CCL2 and IL6 as a noninvasive tool for the diagnosis of NASH in clinical practice and to establish criteria for discrimination NASH from NAFL in Egyptian populations with NAFLD. METHOD: In addition to 30 healthy controls, serum samples from 66 NAFLD patients histologically diagnosed by biopsy (32 NAFL and 34 NASH) were analyzed for serum IL6, CCL2, liver biomarkers, complete blood count and lipid profile. Serum IL6 or CCL2 levels were tested for correlation with the NASH activity score (NAS score). RESULT: Both IL6 and CCL2 were significantly upregulated in NASH patients compared with NAFL patients or control. Serum CCL2 was significantly correlated with the degree of hepatocytes ballooning (the diagnostic endpoint for NASH) without any significant correlation with steatosis or lobular inflammation. Serum IL6 was not correlated with the NAS score. The ROC curve analysis of CCL2 for NASH diagnosis revealed an area under curve (AUROC) of 0.959 at cutoff ≥227 pg/ml. While IL6 revealed an (AUROC) of 0.790. CONCLUSION: Serum CCL2 but not IL6 is a promising noninvasive tool for NASH diagnosis and CCL2 can provide a reliable, validated scoring system to discriminate NAFL from NASH in the Egyptian population confirming the role of CCL2 in NASH pathogenesis. These findings will aid in the development of innovative NASH treatment strategies in Egypt and improve the quality of clinical care.

Fecal calprotectin as a predictor of COVID-19 severity

Coronavirus disease 2019 (COVID-19) is highly transmittable through contact with respiratory droplets. The virus is also shed in fecal matter. Some patients may present with effects in more than one system; however, there are no defined biomarkers that can accurately predict the course or progression of the disease. The present study aimed to estimate the severity of the disease, to correlate the severity of the disease with biochemical predictors, to identify valuable biomarkers indicative of gastrointestinal disease, and to determine the cutoff values. A cross-sectional study was conducted on COVID-19 patients admitted to the Kafrelsheikh University Hospital (isolation unit) between July 10, 2020, and October 30, 2020. The diagnosis of COVID- 19 was confirmed via reverse transcription-polymerase chain reaction (RT-PCR), which was employed for the detection of the viral RNA. We conclude that lymphopenia, elevated C-reactive protein (CRP) level, and liver enzymes were among the most important laboratory findings in COVID-19 patients. Statistically significant differences in platelet count, neutrophil count, D-dimer level, and fecal calprotectin levels were observed among patients presenting with chest symptoms only and patients with both chest and gastrointestinal symptoms (p=0.004;<0.001; 0.010; 0.003; and<0.001, respectively). C-reactive protein, D-dimer, and fecal calprotectin levels positively correlated with disease severity. The cutoff value for fecal calprotectin that can predict gastrointestinal involvement in COVID-19 was 165.0, with a sensitivity of 88.1% and a specificity of 76.5%. (AU)
