Clinical Trial Summary

Feasibility study to understand and gain preliminary information on tolerability and palatability of an oral nutritional supplement gel in a clinical Primary Ciliary Dyskinesia population. To determine if dietary intake is affected by the consumption of the nutritional supplement. Explore possible future outcome measures that could be important in determining impact of this nutritional intervention on this patient group. Participants will be provided with the gel supplements and alongside will have other standard and non standard care measures assessed lung function (FEV1%) number of exacerbation's during study period vitamin D status Bio impedance analysis (BIA) skin-fold measures (e.g. Tricep Skin-fold (TSF) Mid upper arm circumference (MUAC) Handgrip strength (HGS) quality of life measures 6-minute walking tests. Hypothesis Patients with PCD can successfully consume 2 gel supplements per day for a period of 3 months with no effect on dietary intake.

Description:

This is a single site study taking place in a regional PCD clinic. Participants are screened via patient online data system by lead consultants and contacted via telephone to outline study and provide information and contact for queries. participant information sheet and pre-test guidance to be sent to participant prior to next scheduled clinic appointment. Participants attend their usual clinic appointments where routine care measures are completed by healthcare assistants and lead consultants. They then have opportunity to ask study coordinator any questions and complete consent for additional measures to be recorded. This is followed by a trial of the supplement to check for immediate tolerance followed by completion of consent to partake in study and initial palatability and acceptability records. 3 month supply of supplement is provided along with storage and consumption instructions (consume 1 at breakfast and 1 at lunch) a waste box to retain consumed sachets and record time of consumption. Additional telephone appointment made for 1 month to collect further palatability and acceptability along with dietary 24 hour recall. Participant is contacted via telephone at month 1 and 2 to recheck tolerability, acceptability, palatability and dietary intake. Participant can withdraw at any time if unable to continue to tolerate gel supplement. Participant returns to clinic at month 3 to repeat all standard measures, additional outcomes and palatability, acceptability and dietary intake. participant has completed study offered further dietary support through usual clinic route with registered dietitian. Participants can withdraw from the study at any point without giving any reason. Any data collected from them up until that point can be used in analysis. As this is a feasibility study a sample size calculation is not required. The PCD population within the regional clinic at time of recruitment is 54. All patients with PCD will be approached for inclusion in this feasibility if they meet the inclusion criteria until minimum number of 15 and maximum of 20 is reached.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage consumption of supplement gels	To measure through percentage (%) consumed by return of empty sachets over period of three months for each participant	3 months
Primary	Assessment of palatability of supplement gels	To measure using hedonic rating scale (like a lot, like a little, neither like nor dislike, dislike a little, dislike a lot) the appearance, aroma, taste, sweetness, texture mouth feel over the study period of 3 months for each participant	3 months
Primary	Measurement of dietary intake	To collect dietary intake at monthly intervals (baseline, one, two and three) using multiple pass 24 hour recalls conducted through face to face and telephone interviews at each time point recording all food and drink consumption. This is then analysed via Nutritics software, for each participant	3 months
Secondary	Lung Function (Forced Expiratory Volume1 %, Forced Vital Capacity %)	Determine if any changes occur during 3-month period of supplementation	3 months
Secondary	Body Mass Index	Weight and height will be combined to report BMI in kg/m2	3 months
Secondary	Medical Research Council (MRC) breathlessness score	Will be assessed at initial and end points using the degree of breathlessness related activity. Scale is 1-5 (not troubled by breathless except on strenuous exercise to too breathless to leave the house or breathless when dressing and undressing) therefore the higher the score the worse the outcome	3 months
Secondary	Vitamin D levels	To determine any changes during supplementation period	3 months
Secondary	Number of infections over study period	Recorded as part of routine care the number of infections requiring antibiotic treatment either intravenous or oral) over the study period	3 months
Secondary	Quality of life outcome SF-36 questionnaire	Completion of SF-36 quality of life questionnaire questionnaire which is used to determine generic health concepts of functional status and wellbeing. Completed at baseline and end of study period. The higher the score the better the health outcomes	3 months
Secondary	Quality of Life outcome St Georges Respiratory Questionnaire	Completion of St Georges Respiratory questionnaire designed to measure health impairment in respiratory conditions. The results are calculated out of 100 with 100 being the worst possible outcomes and 0 the best.	3 months
Secondary	Habitual activity estimation scale (HAES)	HAES scale which establishes daily activity levels at baseline and end of study for one typical weekday and one typical weekend day and using percentage of time spent on those activities out of 100%.	3 months
Secondary	Hand grip strength dynamometry	Measurement of muscle functionality using hand grip dynamometer recorded as kg/f (kilograms of force)	3 months
Secondary	Tricep skinfold measure	To determine any changes during supplementation period. Measured in millimetres using Harpenden skinfold calipers	3 months
Secondary	Mid upper arm circumference	To determine any changes during supplementation period measured in centimetres, measured using an identified mid point between the acromion and olecranon processes using a tape measure	3 months
Secondary	Six minute walk tests	To determine any changes during supplementation period	3 months
Secondary	Bio electrical impedance analysis	Measure the electrical resistance of tissue to determine skeletal muscle mass reported as percentages and kilograms of participants at baseline and end point	3 months
Secondary	Bio electrical impedance analysis	Measure the electrical resistance of tissue to determine fat mass (FM), reported as percentages and kilograms of participants at baseline and end point	3 months
Secondary	Bio electrical impedance analysis	Measure the electrical resistance of tissue to determine fat free mass (FFM) reported as percentages and kilograms of participants at baseline and end point	3 months
