Management of Portal Hypertension in Children

Management of portal hypertension in children has evolved over the past several decades. Portal hypertension can result from intrahepatic or extrahepatic causes. Management should be tailored to the child based on the etiology of the portal hypertension and on the functionality of the liver. The most serious complication of portal hypertension is gastroesophageal variceal bleeding, which has a mortality of up to 30%. Initial treatment of bleeding focuses on stabilizing the patient. Further treatment measures may include endoscopic, medical, or surgical interventions as appropriate for the child, depending on the cause of the portal hypertension. β-Blockers have not been proven to effectively prevent primary or secondary variceal bleeding in children. Sclerotherapy and variceal band ligation can be used to stop active bleeding and can prevent bleeding from occurring. Transjugular intrahepatic portosystemic shunts and surgical shunts may be reserved for those who are not candidates for transplant or have refractory bleeding despite medical or endoscopic treatment

Prospective multicentre study on antibiotic resistance of Helicobacter pylori strains obtained from children living in Europe

Aim: To prospectively assess the antibacterial resistance rate in Helicobacter pylori strains obtained from symptomatic children in Europe. Methods: During a 4-year period, 17 paediatric centres from 14 European countries reported prospectively on patients infected with H pylori, for whom antibiotic susceptibility was tested. Results: A total of 1233 patients were reported from Northern (3%), Western (70%), Eastern (9%) and Southern Europe (18%); 41 % originated from outside Europe as indicated by mother's birth-country; 13% were <6 years of age, 43% 6-11 years of age and 44% >11 years of age. Testing was carried out before the first treatment (group A, n = 1037), and after treatment failure (group B, n = 196). Overall resistance to clarithromycin was detected in 24% (mean, A: 20%, B: 42%). The primary clarithromycin resistance rate was higher in boys (odds ratio (OR) 1.58; 1.12 to 2.24, p = 0.01), in children <6 years compared with >12 years (OR 1.82, 1.10 to 3.03, p = 0.020) and in patients living in Southern Europe compared with those living in Northern Europe (OR 2.25; 1.52 to 3.30, p<0.001). Overall resistance rate to metronidazole was 25% (A: 23%, B: 35%) and higher in children born outside Europe (A: adjusted. OR 2.42, 95% CI: 1.61 to 3.66, p<0.001). Resistance to both antibiotics occurred in 6.9% (A: 5.3%, B: 15.3%). Resistance to amoxicillin was exceptional (0.6%). Children with peptic ulcer disease (80/1180, 6.8%) were older than patients without ulcer (p = 0.001). Conclusion: The primary resistance rate of H pylori strains obtained from unselected children in Europe is high. The use of antibiotics for other indications seems to be the major risk factor for development of primary resistance

Prospective multicentre study on antibiotic resistance of Helicobacter pylori strains obtained from children living in Europe

AIM: To prospectively assess the antibacterial resistance rate in Helicobacter pylori strains obtained from symptomatic children in Europe. METHODS: During a 4‐year period, 17 paediatric centres from 14 European countries reported prospectively on patients infected with H pylori, for whom antibiotic susceptibility was tested. RESULTS: A total of 1233 patients were reported from Northern (3%), Western (70%), Eastern (9%) and Southern Europe (18%); 41% originated from outside Europe as indicated by mother's birth‐country; 13% were <6 years of age, 43% 6–11 years of age and 44% >11 years of age. Testing was carried out before the first treatment (group A, n = 1037), and after treatment failure (group B, n = 196). Overall resistance to clarithromycin was detected in 24% (mean, A: 20%, B: 42%).

Frequency and risk factors of gastric and duodenal ulcers or erosions in children: A prospective 1-month European multicenter study

There are no solid figures of the frequency of ulcer disease during childhood in Europe. We assessed its frequency and analyzed known risk factors. PATIENTS AND Methods: Ulcers, erosions, indications, and risk factors were recorded in all children undergoing an upper gastrointestinal endoscopy in a prospective study carried out during 1-month simultaneously in 19 centers among 14 European countries. Results: Ulcers and/or erosions were observed in 56 out of 694 children. Children with ulcers/erosions were significantly older than those without lesions (10.3±5.5 vs. 8.1±5.7 years, P=0.002). Helicobacter pylori infection was present in 15 of 56 children (27%) where NSAIDs were used in eight, steroids in five, immune-suppressive drugs in five, antibiotics in six, antacids in one, H2-blockers in six and proton pump inhibitors in eight children (more than one risk factor was detected in 32 of 56 children). No risk factors were observed in 24 of 56 children (43%). The main indications for endoscopy were epigastric or abdominal pain (24%) and suspicion of gastroesophageal reflux disease (15%). Similarly, epigastric tenderness, hematemesis, melena, and weight stagnation were significantly associated with ulcers/erosions, whereas sex, H. pylori infection, socioeconomic and lifestyle factors were equally distributed. Conxlusion: Although limited by the short-time duration and the heterogeneity of the patients included throughout the 19 centers, our study shows a frequency of 8.1% of ulcers and/or erosions in children, occurring mainly in the second decade of life. H. pylori infection and gastrotoxic medications were less frequently implicated than expected. Copyright © Lippincott Williams &amp; Wilkins

Results from the pediatric European register for treatment of Helicobacter pylori (PERTH).

Data on the eradication treatment for childhood Helicobacter pylori are scanty. A register was established on the European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) website to collect data on treatment performed by European pediatricians to ascertain what is practiced in the field.Journal ArticleMulticenter StudySCOPUS: ar.jFLWINinfo:eu-repo/semantics/publishe
