Clinical Trial Summary

A significant group of children with functional constipation (FC) continues to have symptoms despite recommended standard therapy. Underlying psychiatric problems could explain therapy resistance. However, a work-up for psychiatric problems is only recommended after unsuccessful 6 months standard therapy. Earlier detection and check-up could lead to faster start-up of a more adequate therapy. Therefore, we investigate the prevalence of emotional, behavioural and social problems in the FC-population at the first contact with a paediatric gastroenterologist in a tertiary care hospital.

Clinical Trial Description

The diagnosis of functional constipation (FC) in children leads to several diagnostic and therapeutic challenges. Most children respond well to standard recommended treatment, but there is a considerable group of patients that will continue to have symptoms. In this group, paediatricians sometimes presume the presence of an underlying psychopathology such as a developmental disorder, mood disorder, behavioural disorder. A longer treatment period has shown strong association with behavioural problems, suggestive for treatment resistant constipation.

It is known that functional defecation disorders (FDD) can be associated with behavioural and developmental disorders, such as Autism Spectrum Disorder (ASD) and Attention Deficit and Hyperactivity Disorder (ADHD), though these disorders are often initially unrecognized. Also, there are no clear guidelines reported regarding the timing when to search for underlying psychopathology in FC.

Research using Social Responsiveness Scale (SRS) and Social Communication Questionnaire-Lifetime (SCQ-L), screening tools for social difficulties, did not identify ASD diagnosis, in children with functional constipation. At the other hand, they found a total increase in emotional and behavioural problems in their research group. Prior studies found that 28 % of children with FDD referred to a tertiary centre scored positive on ASD screening questionnaires. A high prevalence of behavioural problems (37 %) in children with FC has been described as well.

According to the Guidelines for children with FC of the North American and European Societies of Paediatric Gastroenterology, Hepatology and Nutrition, the diagnosis of emotional, behavioural and/or developmental disorders (ASD or ADHD) will be considered after an unsuccessful six-month standard treatment.

We hypothesized that it could be useful to incorporate an earlier screening for emotional, behavioural and autism spectrum disorders into the diagnostic work-up of children with functional constipation referred to a tertiary care hospital. FC may have an important impact on the Quality of Life (QoL) in families of these children. Therefore we also measure parental stress and negative life-events from the child's perspective using the 'Opvoedingsbelasting Vragenlijst' (OBVL) for measurement of parental stress and the 'Vragenlijst Meegemaakte Gebeurtenissen' (VMG) for possible stressful life events from the child's perspective.

This study includes Dutch and French-speaking children, age 4-18 years, presenting for the first time at KidZ Health Castle (KHC) Brussels with suspicion of functional constipation complaints. Children could present ambulatory or could be hospitalized and were eligible regardless of previously diagnosed behavioural and developmental problems and regardless of any previous treatment for FDD. The diagnosis of FC was made based on the Rome IV criteria. Given that the 2 month interval listed in the Rome IV criteria for older children may unfairly delay treatment in some children with constipation, children who had difficulty with defecation for at least 2 weeks were also included 3. Children with an underlying organic cause that could have contributed to the development of constipation and children with functional non-retentive faecal incontinence (FNRFI) will be excluded.

The questionnaires will be given to the consenting parents and/or patients at the first visit and after 6 months conventional treatment along with an explanation of the research by the attending pediatrician, informed consent and a return envelope. Each questionnaire will be anonymized and provided with a code that will be linked to the name and number of the participant's file.

The group within the normal range at first visit for the two screening surveys: SRS-2 and CBC-L will serve as a control group.

Both groups will have to fill in the 2 questionnaires 6 months later, after initiation of adequate treatment. If the control results are still abnormal, participants will be directed to the department of Child and Adolescent Psychiatry for further treatment of their behavioral, emotional or developmental problems.

Participants will be seen every 2 - 3 months and outcome will be evaluated at 6 and 12 months after enrollment. ;
