RESUMO
BACKGROUND: The resistance rate of Helicobacter pylori to clarithromycin (CAM) is high among infected children in Japan. Therefore, a new method for detecting CAM-resistant H. pylori using a minimally invasive technique is strongly desired. We aimed to investigate the clinical usefulness of our newly developed nested polymerase chain reaction-quenching probe (Nested PCR-QP) method using stool specimens. METHODS: We first evaluated our method using a residual solution of the H. pylori stool antigen test for adolescents. Then, we evaluated our method using culture testing for adults. RESULTS: Among 57 middle school students with H. pylori, the Nested PCR-QP test results of 53 (90.3%) were able to be analyzed. A total of 28 students had CAM resistance mutations. We found a genetic mutation in 28 students and no mutation in 23 students, and these results were consistent with those of PCR-direct sequencing. In the 23 adults who were diagnosed with H. pylori infection using the rapid urease test and culture testing, we were able to use Nested PCR-QP for analyzing 21 adults who tested positive in the stool H. pylori antigen test. The results obtained for all 21 adults were consistent with those obtained via the drug susceptibility test. CONCLUSIONS: Our novel method could be useful for non-invasively detecting CAM resistance mutations in H. pylori. This may help select a drug to reduce eradication failure rates against H. pylori.

An 18-month-old girl was suspected fish-bone foreign body on computed tomography. She was finally diagnosed to have the calcification of the ligamentum arteriosum. It is important to be aware of the presence of it to avoid further unnecessary examinations.
RESUMO
Background: Ileocolic intussusception is the most common form of intussusception in children. Intussusception in the appendix or cecum without a lead point in a child is very rare and was found with total colonoscopy (TCS) and computed tomography. Case Presentation: A 9 year-old boy was admitted to our hospital with fever, vomiting, and two episodes of bloody diarrhea. Inflammatory bowel disease was suspected; TCS was performed and revealed intussusception whose advanced region was in the cecum. The diagnosis was idiopathic cecum intussusception. This case was unusual in that intussusception had occurred at a young age but without lead point; in addition, the intussusception had also occurred at the tip of the cecum. The intussusception was safely reduced by endoscopic procedures, and after improvement in the vomiting, the patient was safely discharged and has had no bloody stools since. Conclusion: We demonstrated cecal intussusception without lead point observed on TCS in a child.
RESUMO
RATIONALE: Although percutaneous endoscopic gastrojejunostomy (PEG-J) tubes are believed to reduce the side effect of aspiration, cautious catheter management is required. Intussusception is a serious complication of these tubes. PATIENT CONCERNS: A 7-year-old boy bedridden with hypoxic encephalopathy owing to drowning at the age of 1 year was admitted our hospital with urinary retention for 1 month. At the age of 4 years, a PEG-J tube was inserted. Concomitant with hyperaldosteronemia, an intestinal intussusception from the duodenum to the jejunum was observed via computed tomography (CT). The patient's condition worsened dramatically; gastrointestinal perforation was suspected, and laparotomy was performed. DIAGNOSIS: Jejuno-jejunal intussusception. INTERVENTIONS: Open surgery was performed to release the intussusception. By assessing the reduced intestinal tract, the intussusception starting from a 50 cm portion from the Treitz ligament had been extended to 100âcm from the Treitz ligament. The oral side jejunum was dilated. No evidence of intestinal perforation or strangulated ileus was observed, and the intussusception was manually remediable. OUTCOMES: Preoperative CT examination showed intussusception from the duodenum to the jejunum. Laparotomy showed intussusception on the anal side of the Treitz ligament. With regard to the CT findings associated with the progression of intussusception to the duodenal site, as a result of the telescope phenomenon extending to the duodenum due to the relaxation of the Treitz ligament through repeated intussusception, it was considered that CT examination revealed intussusception extending from the jejunum to the duodenum of oral side. After 3 postoperative weeks, the patient was finally able to return home. LESSONS: If the ileus is observed during the insertion of a PEG-J, clinicians should consider the possibility of intussusception even in the duodenum.

BACKGROUND: Probiotics are beneficial to patients with Helicobacter pylori infections by modulating the gut microbiota. Biofermin-R (BFR) is a multiple antibiotic-resistant lactic acid bacteria preparation of Enterococcus faecium 129 BIO 3B-R and is effective in normalizing the gut microbiota when used in combination with antibiotics. This study aimed to determine the effect of BFR in combination with vonoprazan (VPZ)-based therapy on gut microbiota. METHODS: Patients with positive urinary anti-H pylori antibody test (primary test) and fecal H pylori antigen test (secondary test) were examined. Patients in group 1 (BFR- ) received VPZ (20 mg twice daily), amoxicillin (750 mg twice daily), and clarithromycin (400 mg twice daily) for 7 days. Patients in group 2 (BFR+ ) received BFR (3 tablets/day) for 7 days, in addition to the aforementioned treatments. Following treatment, the relative abundance, α-diversity, and ß-diversity of gut microbiota were assessed. RESULTS: Supplementation with BFR prevented the decrease in a-diversity after eradication therapy (Day 7). ß-diversity was similar between groups. The incidence rate of diarrhea was non-significantly higher in the BFR- than in the BFR+ group (73.1% vs 56.5%; P = .361). Stool consistency was comparable in the BFR+ group on Days 7 and 1 (3.86 ± 0.95 vs 3.86 ± 1.46; P = .415). CONCLUSION: Biofermin-R combined with VPZ-based therapy resulted in higher microbial α-strain diversity and suppressed stool softening during H pylori eradication therapy.

A 13-year-old boy presented to the hospital with a 3-month history of repeated vomiting and abdominal pain. Results of esophagogastroduodenoscopy revealed a diagnosis of eosinophilic gastroenteritis (EGE). We initiated a short-term six-food elimination diet (SFED) and reintroduction therapy over five days. On the third day of SFED, the patient's abdominal symptoms completely disappeared. However, he experienced unbearable abdominal pain six hours after the reintroduction of milk and peanuts. His symptoms remain completely controlled at present after eliminating milk and peanut products. The SFED and reintroduction therapy for EGE may be effective even for short-term treatments over a five-day period.

Citrin deficiency, which is caused by a mutation of SCL25A13, can manifest in older children as failure to thrive and dyslipidemia caused by citrin deficiency (FTTDCD) and in adults as recurrent hyperammonemia with neuropsychiatric symptoms in adult-onset type II citrullinemia (CTLN2). FTTDCD and CTLN2 are known to complicate hypertriglyceridemia and chronic pancreatitis. Here we report, for the first time, the case of a patient with chronic pancreatitis and pancreatic pseudocyst with CTLN2 who was treated using endoscopic ultrasound-guided cyst drainage (EUS-CD). A 33-year-old woman with down syndrome presented to our hospital with complaints of fever, abdominal distention, and biliary vomiting for the previous 2 weeks. Owing to her difficulties in communication, although she had been taking a nutritionally balanced diet regardless of her preference, chronic pancreatitis and pancreatic stones had already been observed at the time of CTLN2 diagnosis at the age of 30 years. Three years later, a merged pancreatic pseudocyst was detected, and EUS-CD was successfully performed. A high-fat diet therapy for FTTDCD and CTLN2 may have caused the development of the pancreatic pseudocyst combined with chronic pancreatitis in this case. Pancreatic pseudocysts associated with FTTDCD or CTLN2 can be treated in a similar manner to those resulting from other causes.

RATIONALE: Helicobacter pylori infection causes atrophic gastritis in childhood, but atrophic gastritis due to H pylori infection is extremely rare in infancy. The relationship between H pylori infection and chronic diarrhea without protein leakage remains controversial. PATIENT CONCERNS: An 8-month-old male infant presented to our hospital with severe watery diarrhea, erythema, and failure to thrive from approximately 1 month after birth. Blood, stool, esophagogastroduodenoscopy, total colonoscopy, and H pylori urease analysis results were positive, thereby suggesting atrophic gastritis. DIAGNOSES: Atrophic gastritis and chronic diarrhea due to H pylori infection. INTERVENTIONS: We performed H pylori eradication therapy using triple therapy with vonoprazan (6âmg/kg), amoxicillin (300âmg/d), and clarithromycin (120âmg/kg) for 7 days. OUTCOMES: From approximately 1 week after the H pylori eradication therapy, the frequency of defecation had decreased, stool shape had improved, and body weight had gradually increased. LESSONS: H pylori infection can cause atrophic gastritis and chronic diarrhea even in infancy. Early eradication therapy for H pylori infection may be useful for prevention of gastric cancer and improvement in growth disorders.

RATIONALE: Eosinophilic esophagitis (EoE) is an inflammatory disease diagnosed based on clinical symptoms and pathological findings. EoE is treated with proton pump inhibitors (PPIs), topical steroids, and elimination diet-reintroduction therapy. After remission is achieved with the elimination diet, foods can be reintroduced sequentially to identify specific food triggers; however, this reintroduction method was not previously standardized. PATIENT CONCERNS: A 12-year-old girl presented to our hospital with a 3-year history of epigastric pain. Esophagogastroduodenoscopy revealed linear furrows, esophageal rings, white exudates, and pallor throughout the esophagus. Histopathological findings revealed eosinophilic infiltration >15âeos/hpf on esophageal biopsy. There were no obvious abnormal findings in the stomach and duodenum. DIAGNOSES: EoE INTERVENTIONS AND OUTCOMES:: Because PPI was ineffective, we proposed a 6-food-group elimination diet (SFGED) and reintroduction therapy for EoE, which was initially planned out over a 6-week interval. However, a 5-day interval of SFGED and reintroduction therapy was performed instead. The treatment was effective and causative food antigens (egg and nuts) were identified. Since her symptoms recovered following short-term treatment, the nutritional impact was minimized, as was the duration of her hospitalization. Consequently, the patient's quality of life was well-preserved. LESSONS: SFGED and reintroduction therapy for EoE may be effective even for short-term treatments involving 5-day intervals.

BACKGROUND: To present the strategies and preliminary findings of the first 3 years after implementing a Helicobacter pylori screening and eradication program to prevent gastric cancer in Saga Prefecture. METHODS: A screening and treatment program to eradicate H. pylori from third-grade junior high students was started in Saga Prefecture in 2016, using local governmental grants. Screening was with urinary anti-H. pylori antibody tests, followed by H. pylori stool antigen tests for students who were antibody positive. Those positive on both tests underwent H. pylori eradication by triple therapy based on a potassium-competitive acid blocker. RESULTS: From 2016 to 2018, the participation rate was 83.1% and the H. pylori infection rate was 3.1% (660/21,042). The participation rates were higher in 2017 (85.4%) and 2018 (85.9%) compared with 2016 (78.5%) (P < 0.0001), and the infection rate also decreased in a time-dependent manner (2016: 3.6%, 2017: 3.3%, 2018: 2.5%, P = 0.0001). In total, 501 students positive for H. pylori received eradication therapy (85.1% success) and adverse events occurred in 20 of these (4.0%). However, no serious complications occurred. CONCLUSIONS: The H. pylori screening and eradication project for school students in Saga Prefecture has started successfully and we have seen both a steady increase in the participation rate and a steady decrease in the infection rate, without major safety concerns.

Coenzyme Q10 deficiency causing gastrointestinal symptoms has not been reported. At least 15 genes are involved in CoQ10 biosynthesis, and one of the genes is AarF domain-containing kinase 4 (ADCK4). This case report first showed a patient who presented with Crohn's disease (CD) combined with ADCK4 glomerulopathy (ADCK4-GN). After approximately 2 years of infliximab treatment for CD, this patient has remained in clinical remission with no adverse effects. Moreover, two important findings were obtained: first, individuals with ADCK4-GN may present with complications, such as CD, which is a gastrointestinal disease, and infliximab may be effective for CD associated with ADCK4-GN. Second, infliximab may also be effective and safe for individuals with CD who are undergoing peritoneal dialysis. Thus, the results of the present study may be used in managing patients with such condition, and as a result, better clinical outcomes will be obtained.

The Quick Chaser H. pylori (QCP), which is a novel antigen detection kit for Helicobacter pylori, was developed recently. The previous examination kits targeted the catalase of H. pylori; however, this new test kit, to the best of our knowledge, is the first kit to target the flagellar protein of H. pylori The present study aimed to evaluate the efficacy of QCP compared with that of the already commercially available rapid test kit Testmate Rapid Pylori Antigen (TRP). TRP and QCP were utilized in 71 participants. The positive and negative concordance ratios of QCP to TRP were 100% (57/57) and 92.9% (13/14), respectively. Sensitivity based on the rapid urease test and culture test was 92.3%. Results of the dilution sensitivity test showed that QCP was eight times more sensitive to an H. pylori standard strain and the clarithromycin (CAM)-resistant clinical isolate and four times more sensitive to a CAM-susceptible clinical isolate than TRP. For the cross-reactivity test, 27 strains that exist in human feces, such as the Helicobacter genus, Bifidobacterium genus, Lactobacillus genus, and other resident bacteria, were selected. The results obtained using QCP were all negative, and no cross-reaction was observed. In conclusion, compared with TRP, QCP can detect H. pylori using clinical specimens with high sensitivity, regardless of CAM susceptibility and tolerance. No cross-reactivity was observed with other intestinal bacteria in humans. The kit is considered extremely useful in clinical settings.
