SUMMARY BackgroundThe most commonly used second-line Helicobacter pylori eradication regimens are bismuth-containing quadruple therapy and levofloxacin-containing triple therapy, both offering suboptimal results. Combining bismuth and levofloxacin may enhance the efficacy of rescue eradication regimens.

Parents of children with EA reported lower mental health compared with the general population, especially mothers, and parents of young children, with severe EA, and a frequent school/kindergarten absence. This shows that parents may experience substantial emotional burden and highlights the need for psychosocial support for EA parents, especially in the first years.

Background Different bismuth quadruple therapies containing proton‐pump inhibitors, bismuth salts, metronidazole, and a tetracycline have been recommended as third‐line Helicobacter pylori eradication treatment after failure with clarithromycin and levofloxacin. Aim To evaluate the efficacy and safety of third‐line treatments with bismuth, metronidazole, and either tetracycline or doxycycline. Methods Sub‐study with Spanish data of the “European Registry on H pylori Management” (Hp‐EuReg), international multicenter prospective non‐interventional Registry of the routine clinical practice of gastroenterologists. After previous failure with clarithromycin‐ and levofloxacin‐containing therapies, patients receiving a third‐line regimen with 10/14‐day bismuth salts, metronidazole, and either tetracycline (BQT‐Tet) or doxycycline (BQT‐Dox), or single capsule (BQT‐three‐in‐one) were included. Data were registered at AEG‐REDCap database. Univariate and multivariate analyses were performed. Results Four‐hundred and fifty‐four patients have been treated so far: 85 with BQT‐Tet, 94 with BQT‐Dox, and 275 with BQT‐three‐in‐one. Average age was 53 years, 68% were women. Overall modified intention‐to‐treat and per‐protocol eradication rates were 81% (BQT‐Dox: 65%, BQT‐Tet: 76%, BQT‐three‐in‐one: 88%) and 82% (BQT‐Dox: 66%, BQT‐Tet: 77%, BQT‐three‐in‐one: 88%), respectively. By logistic regression, higher eradication rates were associated with compliance (OR = 2.96; 95% CI = 1.01‐8.84) and no prior metronidazole use (OR = 1.96; 95% CI = 1.15‐3.33); BQT‐three‐in‐one was superior to BQT‐Dox (OR = 4.46; 95% CI = 2.51‐8.27), and BQT‐Tet was marginally superior to BQT‐Dox (OR = 1.67; 95% CI = 0.85‐3.29). Conclusion Third‐line H pylori eradication with bismuth quadruple treatment (after failure with clarithromycin and levofloxacin) offers acceptable efficacy and safety. Highest efficacy was found in compliant patients and those taking 10‐day BQT‐three‐in‐one or 14‐day BQT‐Tet. Doxycycline seems to be less effective and therefore should not be recommended.

In two of 115 patients' causative CNVs were found (2%). The remaining identified rare CNVs represent candidates for further evaluation. Rare inherited CNVs may constitute modifiers of, or contributors to, multifactorial VATER/VACTERL or VATER/VACTERL-like phenotypes.
