Plain English Summary
Background and study aims
Every day, 24000 children under five die of which more than one third of deaths are associated with malnutrition. Malnourished children have an inability to properly digest food because they lack digestive enzymes made by the pancreas, an abdominal digestive organ. These enzymes are used to break down fats, proteins and carbohydrates into units that can be digested. Loss of digestive enzymes leads to incomplete digestion and insufficient absorption of nutrients. In other diseases with these characteristics, like Cystic Fibrosis, improving this maldigestion with pancreatic enzyme replacement therapy (PERT) is very common. The goal of PERT is to restore normal digestion, achieve adequate nutritional status and to reach a normal pattern of growth. However, we do not know if exocrine pancreatic dysfunction in childhood severe malnutrition can be corrected by PERT and will lead to additional weight gain. Our objective is to test whether PERT results in additional weight gain in severely malnourished children.
Who can participate?
Severely malnourished children, aged between 6 and 60 months, admitted to the ward dedicated to malnourished children: MOYO House or Moyo Nutritional Rehabilitation Unit. Both HIV positive and negative children can participate.
What does the study involve?
100 children will be randomly divided in 2 groups: the group getting the enzymes (PERT) and the control group. Both groups will be treated according to the current departmental refeeding guidelines that are based on what the World Health Organization recommends. The group getting PERT will receive this during a four-week period.
What are the possible benefits and risks of participating?
Several benefits are present for participants. A special study team will follow and take care of the children during the entire admission to MOYO. The study information provided to the parents creates an opportunity to learn more about the nutritional problem and the health of their child.
No more than the maximum recommended daily dose per kilogram bodyweight, as is currently practiced in children with Cystic Fibrosis, will be prescribed. Mild discomfort and minimal bleeding is related to the venous blood drawing.
Where is the study run from?
The study will take place in MOYO Nutritional Rehabilitation Unit, Paediatric Department, Queen Elizabeth Central Hospital, Blantyre, Malawi.
When is the study starting and how long is it expected to run for?
The study will start mid February 2014. We are aiming to recruit all patients within 6 months.
Who is funding the study?
Stichting Steun Emma Kinderziekenhuis (Foundation Support at the Emma Childrens Hospital in Amsterdam). Netherlanfds. See also: http://steunemma.nl/site/stichting/

The OPTIMISM trial: pancreatic exocrine replacement therapy in severely malnourished children: a pilot study
Exocrine pancreatic dysfunction in childhood severe malnutrition can be corrected by pancreatic enzymatic replacement therapy and will lead to enhanced weight gain and ultimately to a reduced morbidity and mortality.

Severe acute malnutrition in children
Children are randomised to two groups: receiving pancreatic enzyme replacement therapy (PERT) or standard treatment. All children admitted to MOYO have a thick blood film examined for parasitaemia and a haematocrit measured. They are all offered an HIV antibody test with appropriate pre- and post counselling. After admission children will be treated according to the current departmental refeeding guidelines that are WHO based. The intervention will be given during a four-week period. PERT is prescribed as 3000 Units Lipase/kilogram bodyweight 3 times per day with an upper limit dose of 10,000 Units Lipase/kg bodyweight per day 35. If the child is discharged before this period, parents will be given transport money to return to the hospital after the four-week period has ended.
Primary outcome measures
1. To compare the percentage of weight gain after 28 days of PERT with the current standard of care (calculated using the final weight at 28 days and the minimum weight during admission)
2. An additional 10% increase in weight will be considered clinically relevant
Secondary outcome measures
We will compare the differences after 28 days of PERT compared to the current standard of care with respect to:
1. Improvement in exocrine pancreatic function assessed by increased serum cationic and faecal elastase-1 levels
2. Decreased time on the ward in the PERT group
3. Overall mortality by 4 weeks in both groups
