CD55 Deficiency, Early-Onset Protein-Losing Enteropathy, and Thrombosis.

BACKGROUND: Studies of monogenic gastrointestinal diseases have revealed molecular pathways critical to gut homeostasis and enabled the development of targeted therapies. METHODS: We studied 11 patients with abdominal pain and diarrhea caused by early-onset protein-losing enteropathy with primary intestinal lymphangiectasia, edema due to hypoproteinemia, malabsorption, and less frequently, bowel inflammation, recurrent infections, and angiopathic thromboembolic disease; the disorder followed an autosomal recessive pattern of inheritance. Whole-exome sequencing was performed to identify gene variants. We evaluated the function of CD55 in patients' cells, which we confirmed by means of exogenous induction of expression of CD55. RESULTS: We identified homozygous loss-of-function mutations in the gene encoding CD55 (decay-accelerating factor), which lead to loss of protein expression. Patients' T lymphocytes showed increased complement activation causing surface deposition of complement and the generation of soluble C5a. Costimulatory function and cytokine modulation by CD55 were defective. Genetic reconstitution of CD55 or treatment with a complement-inhibitory therapeutic antibody reversed abnormal complement activation. CONCLUSIONS: CD55 deficiency with hyperactivation of complement, angiopathic thrombosis, and protein-losing enteropathy (the CHAPLE syndrome) is caused by abnormal complement activation due to biallelic loss-of-function mutations in CD55.

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.

Sinusoidal Obstruction Syndrome During Chemotherapy of Pediatric Cancers and its Successful Management With Defibrotide.

Sinusoidal obstruction syndrome (SOS) is a life-threatening complication generally occurring after hematopoietic stem cell transplantation. SOS after standard dose chemotherapy in malignancies is rare. Between the year 1995 and 2016, 414 patients were diagnosed with acute lymphoblastic leukemia and 113 patients were diagnosed with Wilms tumor in our institution. Among these patients, 4 patients with acute lymphoblastic leukemia (0.96%) and 2 patients with Wilms tumor (1.7%) developed SOS during treatment. SOS behaves like a local disseminated intravascular coagulation. Defibrotide has proved to be effective in SOS. In this article, we report our experience with defibrotide in SOS.

The frequency of the celiac disease among children with familial Mediterranean fever.

We aimed to assess the frequency of celiac disease (CD) in patients with Familial Mediterranean Fever (FMF). This prospective study was carried out from October 2015 to March 2016 and included 303 patients with FMF. We used 98 sex- and age-matched healthy subjects as a control group. Levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in all groups. Those with increased level of tTG IgA were tested for anti-endomysium IgA antibodies (EMA). Patients with positive EMA underwent gastro-duodenoscopy and intestinal biopsy for a definite diagnosis of CD. Only 9 of 303 patients (2.9%) were positive for tTG IgA. Patients positive for tTG IgA were then tested for EMA and only one of them (0.3%) had a positive result. This patient underwent gastro-duodenoscopy. The pathological report was compatible with Marsh 0 classification score for the diagnosis of CD. Two subjects from the control group were positive for tTG IgA but none of them had positive EMA antibodies. We did not find CD in the large cohort of childhood FMF patients. The prevalence of CD did not show association with presence of childhood FMF in this study and CD would not be a considerable complication of childhood FMF.

Clinical features of interleukin 10 receptor gene mutations in children with very early-onset inflammatory bowel disease.

OBJECTIVES: In the present study, we studied a cohort of patients with very early onset inflammatory bowel disease (IBD) to determine the frequency of mutations in the interleukin 10 (IL10) receptor genes as a cause of early-onset IBD. METHODS: Sanger sequencing was performed to determine the presence of IL10 and/or IL10 receptor mutations in 17 patients with a diagnosis of very early onset IBD (disease onset <2 years of age in 15 patients, between 3 and 4 years in the other 2). Mutation screening was performed including all of the coding regions of the IL10, IL10RA, and IL10RB genes. We then compared the follow-up findings of the patients with IL10 receptor mutations in terms of demographic, clinical, laboratory, and treatment response properties with those of patients diagnosed as having very early onset IBD with no mutation. RESULTS: We identified 3 patients bearing mutations in the IL10 or IL10 receptor genes, including 1 mutation in IL10RB that has been described recently (c.G477A, p.Trp159*) and 2 novel mutations affecting the IL10RA gene (c.T192G, p.Tyr64 and c.T133G, p.Trp45Gly). Collectively, these mutations thus provided genetic etiology for 17.6% of the cohort under investigation. The presence of a family history of IBD and the clinical course of Crohn disease differed between patients with mutations in the IL-10 pathway and those without such mutations. Although perianal fistulas were found in all of the patients with IL10 receptor mutations, they were found in only 14.3% of those without such mutations. The lower values of weight-for-age and height-for-age z scores, necessity for more intensive therapy, achievement of longer periods until remission, and frequent relapses in the patients bearing mutations in the IL10 receptor genes all underlined the severity of the disease and its relatively poor response to treatment. CONCLUSIONS: In spite of the small number of patients with mutations affecting the IL-10 signaling pathway in our study, in all of the patients with IL10 receptor mutations, the disease onset occurs at an early age, the prognosis is poor, and the response to treatment is insufficient.

Hereditary tyrosinemia type 1 in Turkey: twenty year single-center experience.

BACKGROUND: Hereditary tyrosinemia type 1(HT1) is a chronic disorder leading to severe hepatic, renal and peripheral nerve damage if left untreated. Despite nitisinone treatment HT1 still carries the risks of hepatocellular carcinoma (HCC) and neuropsychological outcome. METHODS: A retrospective single center study was carried out based on the phenotype, therapy and outcome in 38 Turkish patients with HT1 diagnosed during the last 20 years. RESULTS: None of the patients was diagnosed on newborn screening. The patients were grouped according to acute, subacute and chronic forms of the disorder. The main clinical manifestations were hepatosplenomegaly, liver and renal tubular dysfunction. Thirty-six patients were treated with nitisinone. The mean duration of nitisinone treatment was 64 months and the mean dosage was 1.2 mg/kg/day. Dietary compliance problems were frequent. Eleven patients had cognitive evaluation (mean total IQ, 84 points). Six patients had living donor liver transplantation despite nitisinone treatment: three due to suspected HCC, two for non-compliance to diet, and one for both, at a median age of 90 months. CONCLUSION: Nitisinone treatment is effective and improves both short- and long-term prognosis of HT1. Early diagnosis on newborn screening is needed because delay in treatment increases the risk of the persistence of hepatic disease and HCC. Interruption of the drug can lead to re-occurrence of hepatocellular damage and neurological crisis. Increased α-fetoprotein and new hypoechoic nodule formation are the warning signs for HCC.

Shear wave elastography in the evaluation of liver fibrosis in children.

BACKGROUND: Shear-wave elastography (SWE) is a novel noninvasive method that involves application of local mechanical compression on soft tissue using focused ultrasonography and acquiring strain images that show tissue response. In this study, our goal was to assess the performance of SWE in the staging of liver fibrosis in children with chronic liver disease. METHODS: The study involved measuring SWE values in the right lobe of the liver in a patient group of 76 children with chronic liver disease and a control group of 50 healthy subjects. In the patient group, the shear elastic modulus values were correlated with biopsy results according to the Brunt scoring system (F0: portal fibrosis, F1: perisinusoidal or portal/periportal fibrosis, F2: both perisinusoidal and portal/periportal fibrosis, F3: bridging fibrosis, and F4: cirrhosis). Performance of SWE in estimating liver fibrosis in children was determined based on a receiver-operating characteristics (ROC) analysis. RESULTS: Mean SWE values of the control group and F0 group were not statistically significantly different (P = 0.106). The mean SWE values of the F1, F2, F3, and F4 groups were higher than that of the control group (all P < 0.001). Based on kiloPascal measurement values, the area under the ROC curve was 95.2% (95% confidence interval [CI] 92.1-99.5), with a sensitivity for diagnosing liver fibrosis of 91.5%, a specificity of 94.0%, a positive predictive value of 93.1%, and a negative predictive value of 92.6%. Based on meter-per-second measurement values, the area under the ROC curve was 96.3% (95% CI 92.7-99.8), with a sensitivity for diagnosing liver fibrosis of 93.2%, a specificity of 94.0%, a positive predictive value of 93.2%, and a negative predictive value of 94.0%. Mean SWE values for patients with nonalcoholic steatohepatitis were higher than those in the remainder of the study group. CONCLUSIONS: Although liver fibrosis can be detected using SWE, differentiation of fibrosis stages could not be achieved. The presence of steatosis significantly increased the mean SWE values on elastography and so care should be taken when assessing children with nonalcoholic steatohepatitis.

Association of inflammatory bowel disease with familial Mediterranean fever in Turkish children.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) and familial Mediterranean fever (FMF) share common clinical and biological features. The prevalence of other inflammatory diseases, including IBD, is increased in FMF. We investigated the presence of IBD accompanying FMF in patients who were being followed up with a diagnosis of FMF and the relation of IBD with the MEFV gene mutation. METHODS: A total of 78 children with FMF were enrolled in the study. The patients were included in the study independent of the presence of complaints. Colonoscopy for IBD was performed if any of the following was present: blood mixed with mucus in the stool; chronic diarrhea (loose and frequent stools lasting >4 weeks); abdominal pain incompatible with FMF (localized in a certain part of the abdomen, not occurring during attacks, >3 days); and positive IgA and IgG anti-Saccharomyces cerevisiae antibodies and perinuclear antineutrophil cytoplasmic antibodies. MEFV gene mutations were analyzed in patients diagnosed as having IBD and FMF. RESULTS: Of the 78 patients with a diagnosis of FMF, colonoscopy was performed and biopsy samples were taken in 20 patients (25.6%) who had abdominal pain incompatible with FMF, chronic diarrhea, bloody stools, and/or positive perinuclear anti-neutrophil cytoplasmic antibody or anti-Saccharomyces cerevisiae antibody. Histopathological examination resulted in a diagnosis of IBD in 12 of the 78 patients (15.4%). MEFV gene mutations were present in all 12 patients diagnosed as having IBD. We observed M694 V mutations in 5 of 12 patients (41.7%), M680I mutations in 3 (25%), K695R mutations in 3 (25%), and E148Q mutations in 1 (8.3%). CONCLUSIONS: We found that the number of patients with FMF was higher than the number with IBD in the general population. When IBD accompanied FMF, the most common mutation was M694 V; however, the high rate (25%) of K695R mutation in our patients with FMF and IBD was not observed in previous studies.

Accuracy Rate of Shear Wave Elastography in Detecting the Liver Fibrosis in Overweight and Obese Children with Hepatosteatosis.

OBJECTIVE: The aim of this study was to compare the accuracy rate of liver stiffness calculated by shear wave elastography with liver biopsy results in obese and overweight children. MATERIALS AND METHODS: Obese and overweight children between 3 and 18 years of age, who had hepatic steatosis and a healthy control group were included in this study. A blood sample was obtained for laboratory tests and shear wave elastography was performed for all subjects. Liver biopsies were performed only in patients with hepatosteatosis, providing permission for biopsy, and for whom the biopsy procedure was not contraindicated. RESULTS: A cohort of 142 children (78 overweight/obese and 64 healthy) was included in this study. Shear wave elastography values were significantly higher in the patient group as com- pared to the control group (34.0 vs. 8.2 kPa; P < .001). Obese children had higher elastog- raphy values compared to non-obese children (50.2 vs. 23.7 kPa, P < .001). No correlation was detected between fibrosis score and elastography values. Elastography increased with increasing weight (correlation coefficient: 0.334, P = .003) and body mass index (correlation coefficient: 0.364, P = .001). CONCLUSION: In obese and overweight patients, elastography values are higher than in healthy subjects as well as patients with liver fibrosis. Disease-specific cut-off, mean, and normal ref- erence range values should be defined with large-scale studies to improve interpretation of elastography values. Our results are contradictory in the determination of liver fibrosis with shear wave elastography in obese and overweight patients, thus further research with a larger patient population is recommended.

Lactoferrin levels in the gastric tissue of Helicobacter pylori-positive and -negative patients and its effect on anemia.

AIM: To determine gastric tissue lactoferrin (Lf) levels of Helicobacter pylori- (Hp-) positive and -negative patients and its effect on anemia. METHODS: Cases in which initial presentation was of abdominal pain and that were Hp-positive at endoscopy were included. Hp-positive cases and -negative controls were divided into two groups. RESULTS: The study included 64 cases (average: 10.2 ± 0.4 years, 39 male and 25 female). Lf levels were subsequently studied on 61 cases. 45 (73.8%) of these were Hp-positive, while 16 (22.2%) were Hp-negative. In Hp-positive cases, mean staining percentages and density of glands in the antral mucosa were 45.5 ± 4.7% and 1.9 ± 0.1, respectively. Hp-negative cases showed significantly different values of 17.8 ± 4.5% and 1.3 ± 0.2, respectively. Hemoglobin and serum ferritin values of Hp-positive cases were 12.7 ± 0.2 g/dL and 32.5 ± 2 ng/mL, but these were comparable with Hp-negative cases (12.6 ± 0.1 g/dL and 30.7 ± 4.4 ng/mL). CONCLUSIONS: Tissue Lf was significantly higher in Hp-positive cases compared to Hp-negative cases, but no difference was observed between the two groups with regards to hemoglobin and ferritin level. As a result, it is difficult to say that this rise in Lf plays a role in the development of iron deficiency anemia in Hp-positive patients.

Effects of the contact isolation application on anxiety and depression levels of the patients.

This study was aimed to assess the effects of contact isolation application on anxiety and depression levels of the patients, the effects of certain sociodemographics and patient characteristics on anxiety and depression levels, and the thoughts of the isolated patients about contact isolation. This non-randomized quasi-experimental study was carried out with 60 isolated and 57 non-isolated patients with hospital infection. The data were acquired from Hospital Anxiety and Depression Scale (HADS-A (anxiety) and HADS-D (depression)) and patient information form. There was no statistically significant difference between the anxiety and depression levels of the isolated and non-isolated patients. In the isolated patients, the depression points were higher in patients who were, women, received primary education and had lower income levels. Of the patients, 86.4% of them told that they were happy to be in the isolation room. Contact isolation application did not affect anxiety and depression levels of the patients. However, personal attributes increased the development of depression. In contact isolated patients, personal attributes should be taken into consideration in nursing care planning to prevent development of depression.

Maternal psychopathology and psychomotor development of children with GERD.

OBJECTIVES: The relation between gastroesophageal reflux disease (GERD) and maternal psychopathology as well as the role of impairments in mother-child interactions in the perpetuation of feeding problems in children with GERD was previously implicated but not confirmed. The present study aimed to study the relation between maternal psychopathology and feeding problems in children with GERD and the effects of GERD on the psychomotor development of children. SUBJECTS AND METHODS: The case group included 39 children with GERD and their mothers and the comparison group included 39 healthy children and their mothers. The groups were matched for age, gestational age, socioeconomic status, and sex. Scales used for the psychiatric assessment of mothers were the Beck Anxiety Inventory, Hamilton Rating Scale for Depression, Eating Attitudes Test, and Experiences in Close Relationships-Revised. The children's developmental levels were assessed by the Brunet-Lezine Revised test. RESULTS: Maternal Beck Anxiety Inventory, Hamilton Rating Scale for Depression, Eating Attitudes Test, and Experiences in Close Relationships-Revised scores were significantly higher in the case group. Forced feeding and maternal thoughts of the child's feeding as insufficient were associated with a high level of maternal attachment-related anxiety and avoidance. Children with GERD had significantly lower Brunet-Lezine-Revised scores. CONCLUSIONS: Maternal psychopathology, especially insecure attachment, may play a role in the feeding problems in children with GERD. Children with GERD should be examined for maternal psychopathology and feeding problems so that maladaptive feeding behaviors can receive appropriate intervention before the development of negative reinforcement to feeding. The psychomotor development of children should be kept in mind.

Hand-washing behaviour and nurses' knowledge after a training programme.

The aim of this study was to evaluate the nurses' hand-washing behaviour and knowledge before and after a training programme. This prospective study involved 200 nurses who participated in hand-washing training at a university hospital in Turkey. The data were collected using a personal information form and pre- and post-test surveys that had been developed by the researchers. During the study, the nurses received 40 min of training on hand washing and a handbook prepared by the researchers. The hand-washing behaviour and knowledge of the nurses were assessed before training and 1 month after the training. To analyse the data, descriptive statistics, a t-test and a Mc Nemar chi-squared test were used. Following the training, there was a significant increase in the frequency of hand washing by the nurses (t = -2.202, P = 0.029), together with an increase in the time allowed for hand washing (P = 0.024, P < 0.05), knowledge of hand-washing practices (t = -16.081, P < 0.05) and quality (t = -10.874, P < 0.05). Planned training programmes for hand washing should be implemented to improve the behaviour and knowledge of nurses.

Clostridium difficile Colonization Before and After Hospitalization in Children.

BACKGROUND: Beginning in the early 2000s, Clostridium difficile infection has become a major health problem in the United States, Canada, and in most European countries and has not only increased in incidence but also the severity. There are 2 conditions for the development of C. difficile infection: disruption of the normal gastrointestinal flora, and exogenous ingestion of the microorganism. We aimed to study C. difficile colonization in hospitalized children. We identified 2 issues: (1) the relationship between risks before hospital admission and colonization on the first day of hospitalization and (2) the effect of the factors that patients are exposed to during hospitalization on the colonization status at discharge. METHODS: Patients aged between 2 and 18 years who were hospitalized with various diagnoses were included in this study. C. difficile toxin A/B was investigated in the stool samples taken on the admission and discharge days. RESULTS: One hundred six patients were included in the study, of whom 24.5% and 48.1% of hemato-oncology patients were positive for C. difficile toxin A/B. Antibiotic usage within 1 month preceding hospitalization and the presence of underlying disease impact the C. difficile colonization status on the first day of hospitalization. CONCLUSION: Toxigenic C. difficile colonization prevalence is high in hospitalized children, especially in the hemato-oncology patient group.

Familial Mediterranean Fever Mutation Analysis in Pediatric Patients With Inflammatory Bowel Disease: A Multicenter Study.

BACKGROUND: The aim of the study was to evaluate familial Mediterranean fever (FMF) mutation analysis in pediatric patients with inflammatory bowel disease (IBD). The relation between MEFV mutations and chronic inflammatory diseases has been reported previously. METHODS: Children with IBD (334 ulcerative colitis (UC), 224 Crohn's disease (CD), 39 indeterminate colitis (IC)) were tested for FMF mutations in this multicenter study. The distribution of mutations according to disease type, histopathological findings, and disease activity indexes was determined. RESULTS: A total of 597 children (mean age: 10.8 ± 4.6 years, M/F: 1.05) with IBD were included in the study. In this study, 41.9% of the patients had FMF mutations. E148Q was the most common mutation in UC and CD, and M694V in IC (30.5%, 34.5%, 47.1%, respectively). There was a significant difference in terms of endoscopic and histopathological findings according to mutation types (homozygous/ heterozygous) in patients with UC (P < .05). There was a statistically significant difference between colonoscopy findings in patients with or without mutations (P = .031, P = .045, respectively). The patients with UC who had mutations had lower Pediatric Ulcerative Colitis Activity Index (PUCAI) scores than the patients without mutations (P = .007). CONCLUSION: Although FMF mutations are unrelated to CD patients, but observed in UC patients with low PUCAI scores, it was established that mutations do not have a high impact on inflammatory response and clinical outcome of the disease.

Effect of vitamin C on oxidative liver injury due to isoniazid in rats.

BACKGROUND: The aim of the present study was to investigate the effect of different doses of vitamin C on oxidative liver injury due to isoniazid (INH) in rats. METHODS: Rats were divided into four subgroups, each containing 10 rats. Group 1 was the control group; group 2, INH 50 mg/kg per day; group 3, INH 50 mg/kg per day + low-dose vitamin C (100 mg/kg per day); group 4, INH 50 mg/kg per day + high-dose vitamin C (1000 mg/kg per day). INH and vitamin C were administered into their stomachs through an oral tube. After 21 days, measurements were made in both serum and homogenized liver tissues. The levels of glutathione (GSH), superoxide dismutase (SOD) and other biochemical variables were measured. Malondialdehyde (MDA), glutathione peroxidase (GSH-px) and vitamin C were measured using commercial kits. RESULTS: Aspartate amino transferase and alanine aminotransferase in group 2 were higher than those in groups 1, 3 and 4 (P < 0.008 for both). Serum and tissue levels of MDA in group 2 were higher than that in groups 1 and 3 (P < 0.008 for both). There was no difference in the SOD levels between the four groups (P= 0.095). Erythrocyte and tissue GSH in group 2 were higher than that in groups 1 and 3 (P < 0.008 for both). Interestingly, erythrocyte and tissue GSH in group 4 were lower than those in group 1 (P < 0.008 for both). Erythrocyte level of GSH-px in group 2 was higher than that in groups 1 and 3 (P < 0.008 for both). CONCLUSIONS: INH-induced liver injury is associated with oxidative stress, and co-administration of low-dose vitamin C may reduce this damage effectively in a rat model. The antioxidant effect of high-dose vitamin C does not seem more potent compared to the low dose.

Serological screening for coeliac disease in patients with juvenile idiopathic arthritis.

BACKGROUND AND STUDY AIMS: Juvenile idiopathic arthritis (JIA) is characterized by autoimmune aetiology. A gene locus 4q27 related to rheumatoid arthritis, psoriatic arthritis, and coeliac disease is associated with susceptibility to JIA. There are reports indicating several patients with JIA had been diagnosed with CD. We aimed to assess the frequency of coeliac disease (CD) in patients with juvenile idiopathic arthritis (JIA). PATIENTS AND METHODS: This prospective study was carried out from October 2015 to August 2016 and included 96 patients with JIA. All patients were evaluated in terms of clinical and laboratory findings of CD. Levels of total IgA and tissue transglutaminase antibody (tTG) IgA were measured in all patients. Those with increased level of tTG IgA were further tested for anti-endomysium IgA antibodies (EMA). Gastroduodenoscopy were planned for a definite diagnosis of CD in patients with positive EMA. RESULTS: Of the 96 patients in our study, 34 (35.4%) had oligoarticular form of JIA, 29 (30.2%) had polyarticular form, 12 (12.5%) had ERA form, 11 (11.5%) had systemic form, and 10 (10.4%) had psoriatic form. Sixteen of our patients (16.6%) were not using any drugs during the study. Neither EMA IgA antibodies were analysed nor gastro-duodenoscopy was performed because no patients were positive for tTG IgA. There was no difference in terms of tTG levels between the patients using NSAIDs or other drugs. CONCLUSION: We did not find CD in children with JIA. Long term studies with more JIA patients are needed to provide more precise interpretation.

Serological screening for celiac disease in children with systemic lupus erythematosus.

OBJECTIVE: The aim of the present study was to investigate the frequency of celiac disease (CD) in patients with juvenile systemic lupus erythematosus (JSLE) and the potential association of JSLE and CD. METHODS: This was a cross-sectional study performed from October 2015 to October 2017. A total of 50 patients with JSLE were included in the study. The levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in all patients. Subjects with increased tTG were further evaluated for anti-endomysial antibodies (EMAs). Gastroduodenoscopy and intestinal biopsy were performed in those with increased EMA levels to confirm the diagnosis of CD. RESULTS: The study included 44 (88.0%) female and 6 (12.0%) male patients. Of the 50 patients, 30 (60.0%) received corticosteroids, and only 4 (8.0%) received no therapy at the time of the study. Only 3 (6.0%) patients were positive for tTG IgA. Patients with positive tTG IgA were then tested for EMA IgA antibodies, and none of them had a positive result. CONCLUSION: We did not find CD in children with systemic lupus erythematosus. Studies with more patients with JSLE are needed to conclude a more precise result.
