Pharmacogenetics of trough serum anti-TNF levels in paediatric inflammatory bowel disease.

Aims: Identifying DNA variants associated with trough serum anti-tumour necrosis factor (TNF) levels could predict response to treatment in inflammatory bowel disease (IBD). To date, no specific studies have been performed in children. The aim of this study was to identify genetic variants associated with trough serum anti-TNF levels and whether these variants are differential markers for infliximab and adalimumab.

Pneumonia and purulent pericarditis caused by Streptococcus pneumoniae: an uncommon association in the antibiotic era.

Bacterial pericarditis in children has become a rare entity in the modern antibiotic era. The most common pathogen is Staphylococcus aureus, being Streptococcus pneumoniae an exceptional cause. We present 2 children, who were diagnosed of pneumonia complicated with a pleural effusion that developed a purulent pericarditis with signs of cardiac tamponade.

[Short bowel syndrome and failure intestinal features in our community].

Introduction: Intestinal failure is being an entity with higher prevalence in the pediatric age, especially due to bowel resections causing the appearance of a short bowel syndrome.

Objectives: To determine the prevalence and etiology of cases of short bowel syndrome (SIC) and Intestinal Failure (FI) existing in Andalusia. Analyze factors involved in evolution, the number of transplant patients and to know the time required to achieve enteral autonomy, studying whether there are differences in management between different participants.
