Gastroesophageal reflux with children requiring adenotonsillectomy.

BACKGROUND: Our aim is to determine the incidence of reflux in children older than 3 years requiring adenotonsillectomy and relationship between GER and diagnostic tests. METHODS: Forty-four patients, who were listed for adenoidectomy/tonsillectomy at Pediatric Ear Nose Throat department due to severe hypertrophy, were evaluated for accompanying GER (Group 1). GER was diagnosed as having at least one positive GER test result (including esophagitis or pH monitoring). Twenty children without reflux symptoms were used as healthy control group (Group 2) and LPR was held. RESULTS: Reflux was detected in 32 children requiring adenotonsillectomy (72.7%). LPR score was negative in all patients in Group 2. There was no correlation between pH monitoring and histopathological evaluation of esophagus. There was a correlation between the LPR score and histological esophagitis in the proximal esophagus. CONCLUSIONS: GER was high in patients with adenotonsillary hypertrophy. LPR score and the history of patients are as effective as invasive techniques like pH monitorization and endoscopy in determining GER disease.

Prevalence and Clinical Features of Celiac Disease in Healthy School-Aged Children.

BACKGROUND/AIMS: The aim of this study was to determine the prevalence of celiac disease (CD) in healthy school-aged children in the northern region of Cyprus and to investigate the existence of potential markers that may accompany CD. This is the first study to measure the prevalence of CD in the northern region of Cyprus. METHODS: This study included 3792 school-aged children who were between the ages of 6 and 10 years between January 2015 and October 2016. CD was screened using total serum IgA, IgA anti-tissue transglutaminase (tTG), and IgA antiendomysial (EMA) antibodies. Subjects with selective IgA deficiency were further tested for IgG-tTG. Small intestinal biopsies were performed on all subjects with tTG antibody positivity. Risk factors and symptoms related to CD were evaluated using questionnaires in both the CD and control groups. RESULTS: Of the 3792 subjects, 39 were antibody positive (IgA-tTG was positive only in 14 subjects, IgA-tTG plus IgA-EMA in 21 subjects, and IgG-tTG in 4 subjects). IgA deficiency was detected in 11 subjects (0.29%). IgG-tTG was positive in 4 subjects with IgA deficiency (36.3%). Intestinal biopsies were performed on 28 of the 39 seropositive subjects. The biopsy findings of 15 children were consistent with CD (IgA-tTG positive in 3, IgA-tTG and IgA-EMA positive in 10, and IgG-tTG positive in 2). Thus, biopsies confirmed CD in 1:256 children (0.39%). CONCLUSIONS: Our study, which is the first study of school-aged children from the northern region of Cyprus, revealed that CD is a prevalent disease in this region.

Evaluation of malnutrition development risk in hospitalized children.

OBJECTIVES: Many screening methods, such as the Screening Tool Risk on Nutritional Status and Growth (STRONGkids) and the Pediatric Yorkhill Malnutrition Score (PYMS), have been developed to detect malnutrition in pediatric patients. We aimed to explore the prevalence of malnutrition risk in hospitalized children via symptoms and identification of contributing factors, and to examine the efficacy of malnutrition screening tools for hospitalized children. METHODS: STRONGkids and PYMS were applied to 1513 inpatients at 37 hospitals in 26 cities from different regions of Turkey. Physical measurements were collected at hospital admission and at discharge. z-Scores of height-for-age, weight-for-age, weight-for-height, and body mass index-for-age were calculated. RESULTS: Overall, 1513 patients were included in the study. A body mass index standard deviation score of less than -2 was present in 9.5% of the study population at hospital admission, whereas 11.2% of the participants had a weight-for-length/height score of less than -2 at hospital admission. According to STRONGkids results, the proportion of the patients with an underlying chronic disease was higher for the patients at high risk of malnutrition than for the patients at medium or low risk (91% compared with 47% or 45%, respectively). PYMS results indicated that patients at high risk of malnutrition have more chronic diseases (75%) than the patients at medium or low risk of malnutrition (55% and 44%, respectively). CONCLUSIONS: Use of anthropometric measurements in addition to screening tools to identify hospital malnutrition (such as PYMS, STRONGkids) will prevent some nutritional risk patients from being overlooked.

Autoimmune hepatitis and long-term disease course in children in Turkey, a single-center experience.

INTRODUCTION: The aim of this study is to determine clinic and laboratory features, treatment protocols, treatment responses, and long term follow-up of children with autoimmune hepatitis (AIH) in a region of Turkey followed at Ege University. MATERIALS AND METHODS: The records of 47 children with AIH between 1998 and 2012 were retrospectively analyzed for clinical profiles, treatment response, relapse rate, and long-term side effects. RESULTS: The median age of the children was 10±4.1 years (55.3% females). A total of 29 patients presented with chronic hepatitis (61.7%). According to the autoantibody profiles, 40 (85.1%) and seven (14.9%) cases were classified as type 1 and type 2, respectively. Presentation with acute hepatitis and chronic hepatitis was significantly higher in type 1 disease. Laboratory findings at presentation was found similar among races as well as AIH types (P>0.05). The prednisolone was used for remission induction in 37 patients; 86.4% (n: 32) achieved a complete response, 2.7% (n: 1) achieved a partial response, and four patients (10.8%) showed no response. Maintenance was attained by low-dose steroid plus thiopurine and relapse in steroid responders (n: 32) was 9.4% (n: 3) at 8, 12, and 48 months. A total of 36% (n: 24) had neither acute nor chronic treatment side effects. Bone marrow suppression was observed in five patients and hyperglycemia was observed in one patient (10.6 and 2.1%), respectively. CONCLUSION: AIH type 1 prevails in children in a region of Turkey during the second decade of life. Low-dose corticosteroids combined with azathioprine are found.

Prevelance of hepatitis D co-enfection in children with hepatitis B infection: cross-sectional analyses from Western Turkey.

BACKGROUND/AIMS: Effective hepatitis B virus control has warranted a decline in hepatitis B virus prevalence over the world with a relevant reduction in hepatitis B virus-associated delta hepatitis. However, despite the dramatic decline in hepatitis D virus infection rate, no further decrease was recorded after 2000. This cross-sectional study aims to investigate: I- The prevalence of hepatitis D virus co-infection in children with hepatitis B virus infection in Western Turkey; II- The influence of neonatal hepatitis B virus vaccination on hepatitis D virus co-infection rate; and III- The impact of co-infection on prognosis of liver disease. MATERIALS AND METHODS: Serological markers of hepatitis B virus and hepatitis D virus infections were determined by ELISA in patients with chronic hepatitis during immune tolerance, immunoactive, HBeAg-negative chronic, and inactive carrier state. Delta co-infection rate was evaluated in two groups, children born before and after the national neonatal mass vaccination has started (before and after 2000). Viral load, serum alanine aminotransferase, and histological grade were evaluated in co-infected cases. RESULTS: Overall hepatitis delta virus infection rate was 1,76% (3/170); two patients with eAg-negative chronic hepatitis B and one patient in the immunoactive phase were infected with hepatitis D virus. Mean fibrosis score of hepatitis D virus -infected cases and hepatitis B virus -infected counterparts were 4±1,7 and 1,3±1, respectively (p: 0,006). Hepatitis D virus infection was detected in 2 out of 158 children born before and in 1 of 12 born after the neonatal vaccination program. Hepatitis B e-antibody was detected in two patients with delta co-infection (11 and 6 years old), and all mothers of delta hepatitis cases were chronically hepatitis B virus-infected. CONCLUSIONS: Delta hepatitis is rare among hepatitis B virus-infected children in the Western region of Turkey. Despite the success of the national vaccination program, delta hepatitis is not a vanishing disease and it has a grave prognosis due to development of early cirrhosis.

An autoimmune disease refractory to immunosuppressive regimens: celiac disease diagnosed long after liver transplantation.

CD is defined as T-lymphocyte-mediated gluten sensitivity. Although CD is known to affect the small intestine, it is nonetheless a multisystem disorder. Liver involvement in CD may vary from isolated hypertransaminasemia to cirrhosis. Because CD is an inappropriate immune response to gluten proteins, strict gluten-free diet is the principal therapy, along with management of liver dysfunction. In patients who fail to respond to a gluten-free diet, immunosuppressive drugs may improve intestinal inflammatory activity in untreated CD. The present case report is of a 25-yr-old woman with diarrhea lasting several weeks. The patient had received a liver transplant 13 yr earlier, and presented with cryptogenic cirrhosis diagnosed as CD. This appears to be the first case of its kind in which a pediatric long-term liver transplant patient presents with diarrhea eventually diagnosed as CD whose diet included gluten, and who was treated by an immunosuppressive drug regimen. Because of the normalization of CD-related antibodies in the post-transplantation period without gluten restriction, CD should be part of a list of diagnostic possibilities in liver transplant patients presenting with diarrhea of unknown etiology.

The diagnostic value of multimodal evoked potentials in the determination of subclinical neurological involvement of Wilson's disease.

AIMS: Wilson's disease (WD) is a progressive degeneration of hepatolenticular tissue caused by excessive tissue-damaging copper accumulation and in which liver involvement most frequently presents in childhood. Neurological signs also accompany liver disease with time. However, subclinical neurological involvement may occur earlier and diagnostic methods that reveal this subclinical involvement are not well established. The aim of the current study is to assess the subclinical neurological involvement by using multimodality evoked potential (EP) measurements and to explore the relationship between neurological disease and the severity of liver damage. METHODS: The patient group included 28 children (mean age 11.8 ± 2.9 years, range 5.5-17) diagnosed with WD and a control group included 24 age-matched healthy children. Multimodality EP tests (Nihon Kohden Neuropack 8 4200K) of both groups were performed at the Department of Neurology Electrophysiology Laboratory of Ege University. RESULTS: At least one abnormal EP value was observed in 53.5% of the children in the patient group. At least on one side, there were abnormal values for visual evoked potential (VEP) P100, brainstem auditory evoked potential (BAEP) and somatosensory evoked potential (SEP), where the ratios were 25, 28.5, and 11%, respectively. Absolute latency values of patients with right-side VEP P100 and left-side BAEP I, and the interpeak latency values of right-side BAEP I-III were significantly high. The difference in right-side BAEP I-III interpeak latency between cirrhotic and noncirrhotic groups was found to be statistically significant (P<0.05). CONCLUSION: The EP examinations can be an indicator of subclinical brain damage in non-neurological WD; however, cirrhosis because of WD does not cause an increase in the EP values. Detection of changes in the EP values periodically, especially at the time of diagnosis and during the treatment follow-up, may be valuable for revealing subclinical impairment.

Gastroesophageal reflux in children with functional constipation.

BACKGROUND/AIMS: Functional constipation and gastroesophageal reflux disease are two major and commonly encountered components of childhood functional gastrointestinal disorders. Epidemiological studies in the adult population support that there is a significant overlap between the different functional disorders of the digestive tract. Therefore, we aimed to investigate the frequency of gastroesophageal reflux disease in children with functional constipation and to compare clinical findings and 24-h esophageal pH monitoring with a group of patients with suspected gastroesophageal reflux disease. MATERIALS AND METHODS: Children between 4 and 16 years old with functional constipation (based on Rome III criteria, Group 1; n=38) were prospectively evaluated. A control group was composed of patients with symptoms suggesting gastroesophageal reflux disease (Group 2; n= 40). All patients included in the study were asked about reflux-related symptoms, and then all cases underwent 24-h esophageal pH monitoring analysis. RESULTS: Delayed gastric emptying symptoms such as belching and hiccups were more common in patients in Group 1 (p=0.002, p=0.021, respectively), whereas chronic cough was more common in patients in Group 2 (p=0.012). According to the 24-h esophageal pH monitoring, pathologic acid reflux in the lower and/or laryngopharyngeal portion of the esophagus was determined in 39.5% of the patients in Group 1 and in 42.5% of the patients in Group 2 (p=0.96). No significant difference was found in terms of age, gender and duration of constipation in patients with and without acid reflux in Group 1 patients. Pyrosis (66.6 vs. 0%, p=0.00001)was more common in Group 1 patients with acid reflux, but hiccups (20 vs. 69.5%, p=0.007) and belching (33.3 vs. 60.8%, p=0.184) were more common in patients in Group 1 without acid reflux. CONCLUSIONS: Gastroesophageal reflux disease should be considered in the treatment and monitoring of patients with functional constipation. Further studies are needed using 24-h pH multichannel impedance.

Peptic ulcer disease in children: an uncommon disorder with subtle symptomatology.

BACKGROUND/AIMS: Data concerning peptic and infectious ulcers in children are limited. The aim of the study was to investigate the prevalence, presenting symptoms and significance of symptomatology in ulcer diagnosis in the pediatric age group. MATERIALS AND METHODS: Between January 2000 and 2009, upper gastrointestinal endoscopy charts were examined retrospectively. All children in whom a diagnosis of ulcer was established were included in the study. Demographic, clinical, endoscopic, and histopathologic data were obtained from the patients' records. Peptic ulcer disease prevalence, presenting symptoms and symptomatology were evaluated. RESULTS: Ulcer disease was observed in 31 (3.4%) of 902 patients. The mean age was 10.85 ± 4.25 (range: 2-17 years), and the male to female ratio was 2:1. The most common symptom was chronic abdominal pain (68%), hematemesis and melena (55%) and vomiting (39%). Helicobacter pylori was identified in 19 patients (61%) with ulcer. In the Helicobacter pylori-positive group, upper intestinal bleeding and pain were the major symptoms. Symptom frequency was not different between Helicobacter pylori-positive and -negative patients (p>0.05). CONCLUSIONS: Ulcer disease is an uncommon disorder in children with nonspecific clinical symptoms. Unlike the adult population, symptoms fail to diagnose peptic ulcer disease before gastrointestinal bleeding occurs.

Dietary vitamin A intake and serum retinol concentrations of preschool children from different socio-economical levels in Izmir, Turkey.

AIM: Vitamin A deficiency (VAD), especially in its subclinical form, is a world health problem in young children. The aim of this study was to determine the prevalence of VAD among preschool children in various socio-economic groups in Izmir, Turkey. METHODS: One hundred and one children aged 24-59 months were selected for the study with cluster sampling method. A questionnaire was completed by the parents, and the dietary pattern was assessed by using a 3-day dietary record method. RESULTS: Mean serum retinol concentration of the children was 28.3 ± 10.2 µg/dL. Serum vitamin A concentration of two children (2%) was below 10 µg/dL (VAD), whereas 18 (18%) children had vitamin A concentrations between 10 and 20 µg/dL (subclinical deficiency). We did not find any relationship between mean serum retinol concentrations and the independent variables such as socio-economical levels, age groups, birth weight and gestational age. However, there was a statistically significant positive correlation between serum retinol concentrations and weight-for-age and weight-for-height Z scores of the children (p < 0.05). CONCLUSION: Because one-fifth of the children under 5 years have VAD in Izmir, Turkey, nutrition education must be given to the families during well-child care visits, and routine vitamin supplementation should be considered especially in children with malnutrition.

Steroid response in moderate to severe pediatric ulcerative colitis: a single center's experience.

BACKGROUND: we aimed to analyze clinical and inflammatory markers of steroid non-response in patients with moderate/severe ulcerative colitis (UC) at the time of diagnosis. METHODS: this study included patients who were graded as having moderate/severe UC and received corticosteroids as first-line therapy. Demographic, clinical and laboratory findings and pediatric ulcerative colitis activity scores (PUCAS) were recorded. Response to corticosteroids was assessed 30 days after the induction and long-term therapy. RESULTS: twenty-eight children were diagnosed as having moderate/severe UC. Their mean age ± SD was 1 2.2 ± 4 years, and 17% were under 5 years of age. PUCAS at their initial admission was 56.9 ± 11.8. UC was observed at the left colon in 9 patients (32.1%), and pancolitis in 19 (67.9%). At the end of the 30th day, UC was completely remitted in 15 patients (53.5%), partially remitted in 2 (7.1%), and no response in 11 (39.2%). Short-term follow-up showed partial remission in 2 patients, and overall remission with steroid in 17 (60.7%). Non-responders were given second-line treatment; steroid dependency was documented in 2 patients (7.1%) and another 2 (7.1%) patients underwent colectomy. Predictors for steroid non-response were analyzed and only PUCAS at the initial admission was found to be associated with non-response to steroids (51.4 ± 11.4 vs. 65.4 ± 6.8, P<0.05). CONCLUSIONS: approximately half of the pediatric patients had complete response to steroid therapy in a long period. PUCAS could be used as a potential marker of "failed response" to steroid, but should be supported with a number of prospective randomized controlled studies.

Determination of intracellular Th1/Th2 type cytokines in lymphocytes of chronic hepatitis B patients treated with interferon-alpha.

BACKGROUND/AIMS: Host-related immune factors in childhood chronic hepatitis B and change in the initial profile with interferon (IFN)-α treatment need to be clarified. METHODS: Sixteen patients were included in the study, and 10 million units of IFN-α treatment 3 times per week for 6 months was initiated. Pre- and post-treatment percentages of interleukin (IL)-2 and IFN-γ in CD4+ T cells were assessed to determine intracellular T helper cell 1 (Th1) type cytokine expression. Similarly, percentages of intracellular IL-2 and IFN-γ were detected to verify cytotoxic T cell 1 (Tc1) type cytokine expression in CD8+ T cells. Percentages of Th2 and Tc2 type cytokine expression (IL-4 and IL-13) were determined in CD4+ and CD8+ T cells, respectively. RESULTS: Six (50%) of these were evaluated as having no response and the other half with partial/complete response. All patients had higher percentages of Th2 cells with respect to healthy controls pre-treatment. Tc percentages, both Tc1 and Tc2, were significantly different between these groups, being higher in the patient group. When values of the nonresponder group were compared with healthy controls, IL-4 expression was higher and the percentages of Th1 type cells were significantly low. IL13 expression in Th and Tc cells decreased after 6 months of treatment in the unresponsive group. The decrease we observed in Th1 percentages with treatment, in the responsive group, may be due to Th1 deposition shifting from the periphery to liver tissue, as reported before. Intracellular cytokine profiles of treatment responders and normal controls were not different. RESULTS: This is the first study in children comparing baseline and post-treatment intracellular cytokine profiles with values in healthy controls.

Giant cell hepatitis and autoimmune hemolytic anemia after chickenpox.

Autoimmune hemolytic anemia with giant cell hepatitis is a distinct entity in children. It is usually fatal with progressive liver disease. Immunosuppressive treatment with conventional drugs offers some response; however, it is usually only temporary. Alternative therapeutic options with monoclonals have been reported with promising remission of the disease. We report a case with autoimmune hemolytic anemia+giant cell hepatitis after varicella infection. She was resistant to standard immunosuppressive combinations, and rescue therapy with rituximab was used. Remission was not achieved with the drug and the child died with septic complication.

A rare cause of refractory ascites in a child: familial Mediterranean fever.

Familial Mediterranean fever (FMF) is hereditary episodic febrile syndrome characterized by acute attacks of fever and serosal inflammation, generally lasting 1-3 days and resolves spontaneously. Apart from abdominal pain, patients may present with variety of abdominal manifestations such as acute peritonitis, mechanical intestinal obstruction, diarrhea, bowel infarction, amyloidosis and small amounts of peritoneal fluid during the acute attacks. A 6-year-old boy was admitted with massive ascites. After extensive laboratory investigations, no causative agent could be identified. On subsequent days, he developed fever and skin eruptions. Acute-phase reactants were increased. A second tomography revealed cystic fluid collection near the anterior side of spleen that invades the stomach. An exploratory was performed and histopathological examination of the all resected specimens revealed mix inflammatory cell infiltrate associated with severe myofibroblast proliferation suggesting chronic inflammatory process on the mesenteric region. A diagnosis of FMF was suspected based on the clinical, laboratory and histopathological findings, and a trial of colchicine therapy initiated. Ascites and other serosal inflammations improved within 1 week without any recurrence during the next 12-month period on colchicine treatment. Atypical presentations of FMF have been increasingly reported. Pediatricians should keep FMF in mind in the differential diagnosis of massive ascites especially in regions where hereditary inflammatory disease are common.

Infectious complications in pediatric liver transplantation candidates.

We analyzed infections that occurred within one month prior to LT, identified factors associated with their occurrence and effect of infections on post-transplant mortality. The study group included 40 consecutive children who underwent LT. Sites and types of infection and culture results were recorded prospectively. IID was assessed. Risk factors for the infectious events were analyzed. Forty infection episodes were found in 24 patients (60%); 90% were bacterial, 7.5% fungal, and 2.5% viral. Overall, IID was 38.2 per 1000 patient days. Sites of bacterial infection were urinary tract in 13 events (36.1%) and blood stream in 11 events (30.5%). Bacteremia (culture positive infection episodes) was identified in 19 events (52.7%). Gram-negative isolates were twice as frequent as Gram-positive infections (63.1% vs. 36.9%). Risk factors for the infectious complications were young age, low body weight, prior abdominal surgery, chronic liver disease related to biliary problems, presence of ascites, portal hypertension and cirrhosis, and high PELD score (p < 0.05 for all). Infectious complications in pediatric LT candidates are common. Preventive measures are important not only to reduce the infectious complications but also to prevent the post-operative mortality.

Chronic constipation in Turkish children: clinical findings and applicability of classification criteria.

We aimed to evaluate general features of children with chronic constipation and classified them according to the Iowa criteria and Rome II criteria in order to analyze applicability of these criteria in our population. The medical records of 485 children who were referred for chronic constipation over a six-year period were evaluated retrospectively. We found that 7.7% of the cases had an organic pathology, and short segment Hirschsprung disease was the leading cause. Other children (92.3%) were classified as functional constipation, with a mean age of 6.4 +/- 4 years and with slight male dominance. Encopresis was found in 117 children (51.7%) aged over four years, and was associated with older age, male predominance and long duration of symptoms. Both of the classification systems showed a similar prevalence of constipation, but 9.9% of the children with pediatric constipation were not recognized by Rome II criteria. Additionally, 1.8% of the children were not recognized by either Iowa or Rome criteria. Functional constipation is common in primary care, and most of the children were school-aged. Constipation associated with encopresis and nutritional problems such as obesity is less common in developing countries. Rome II criteria are too restrictive and do not recognize approximately 12% of the children. A new classification system must be simple, easy to understand especially by the primary care physician, and must include the common features of constipation recognized by the parents.

Long-term effect of gluten-free diet on growth velocity in Turkish children with celiac disease.

We sought to analyze the long-term growth in children with celiac disease (CD) as well as the association of height and weight SD score at the end of 4 years with the demographic and clinical presentation at initial admission. Thirty-four children with CD were enrolled in the study and followed for at least 4 years. Patients were divided into three groups (Group 1: patients 10 years, at the time of diagnosis). Patients' charts were reviewed for demographic and clinical features at initial admission. Anthropometric measurements at initial admission, at 6th months, and 1st, 2nd, 3rd, and 4th years were recorded. Gluten-free diet led to rapid increase in weight SD and height SD score in patients

Impact of liver transplantation on rate-corrected QT interval and myocardial function in children with chronic liver disease*.

Prolonged QTc interval (>440 ms) is a common abnormality in adult patients with CLD and has been reported to predict patient survival. In this study, 88 children who underwent evaluation for LT, including a 12-lead electrocardiogram and echocardiogram included to determine the frequency of QTc prolongation and related factors in children with CLD and the effect of LT on these factors. Sixty-nine healthy, age- and sex-matched children served as controls. QTc interval was prolonged in 40 CLD patients (45.4%). It was found to be related to PELD score and presence of portal hypertension. Mean QTc was higher in patients who died prior to LT than in the survivors without LT. Mortality risk was increased 3.66-fold in patients with prolonged QTc (p = 0.001, 95% CI: 2-7.2). Cox regression analysis showed that only PELD score was an independent predictor of survival (p = 0.001, beta = -0.41, 95% CI: 5.58-1.82). Five of 48 transplanted children died within three months post-transplant; QTc was not related to post-transplant survival (p = 0.27). QTc normalized in 63.8% patients after LT. After LT, LAD, LVEF, and LVPWT decreased. In conclusion, QTc prolongation is common in children with CLD and associated with high mortality. It may be useful for assessment of the severity of CLD and for the timing for transplantation.

Helicobacter pylori infection in children with celiac disease.

OBJECTIVE: To analyze the prevalence of Helicobacter pylori (H. pylori) infection in children with celiac disease (CD) and to examine the role of H. pylori infection in clinical, laboratory and histopathological presentations of CD. MATERIAL AND METHODS: Data on 96 children with CD and 235 children who underwent endoscopy were compared for the prevalence and gastric histology pattern of H. pylori. Clinical presentation, laboratory and histological findings of CD children with and without H. pylori infection were compared. RESULTS: Twenty-one subjects (21.8%) in the CD group and 56 subjects (23.8%) in the control group had H. pylori gastritis. Gastric metaplasia is higher in CD patients with H. pylori gastritis (19%) than in patients without H. pylori gastritis (1.3%) and in the control group (3.5%) (p<0.05 for all groups). Abdominal distension is more common at initial admission in CD patients with H. pylori gastritis (57.1% versus 14.6%, p<0.05). No significant difference was found between H. pylori (+) and (-) CD patients in terms of prevalence of anemia, iron deficiency and iron-deficiency anemia. Only mild duodenal histological findings were more common in H. pylori patients (57.1% versus 26.7%, p<0.05). CONCLUSIONS: CD may be associated with H. pylori gastritis, but it does not affect the clinical presentation of the disease, except for abdominal distension; CD is associated with mild duodenal lesions. A gluten-free diet improves the symptoms in all patients independently of the presence of H. pylori gastritis. Gastric metaplasia increases in the presence of H. pylori gastritis. Further prospective studies are needed to examine the clinical and histopathological outcomes of gastric metaplasia associated with H. pylori gastritis in CD patients.
