Definitions
- the invention relates to a composition
- a composition comprising a uridine source, an omega-3 polyunsaturated fatty acid for use in the improvement of a subject's coordination, balance, grip strength or fine motor skills.
- the nervous system plays an essential role in a mammal's life.
- cognitive, emotional, social, sensory, motoric and regulatory functions are mainly determined by the brain.
- Brain functioning can become impaired, e.g. due to traumata (e.g. accidents, violence), abuse of drugs (e.g. alcohol) or systematic malnourishment.
- traumata e.g. accidents, violence
- drugs e.g. alcohol
- Malfunctioning of the brain is therefore especially a problem in the elderly and more in particular in the frail or malnourished elderly.
- diseases and disorders which are associated with or find their cause in a badly functioning nervous system are therefore relatively frequently observed. Examples are several forms of dementia, progressive neurodegenerative disorders, mood disorders but also other diseases or disorders like abnormal behaviour.
- WO 2009/002165 relates to a lipid fraction for the support of brain function.
- the lipid fraction comprises hexanoic acid and/or octanoic acid, eicosapentaenoic acid, and more than 0.4 g [alpha]-linolenic acid per 100 g fatty acids of the lipid fraction for the support of brain function.
- the lipid fraction is administered in combination with non-lipid ingredients, but the lipid fraction preferably contributes to more than 45 en % of the energy of a ready to consume product.
- Nucleotides may be added to support brain function.
- the invention relates to a combination of a uridine source and an omega-3-polyunsaturated fatty acid having 18-24 carbon atoms for at least on use selected from

- the invention relates to a use, in particular a non-medical use of a uridine source and an omega-3-polyunsaturated fatty acid having 18-24 carbon atoms for improving coordination of limbs in a mammal, for improving sense of equilibrium in a mammal, for improving forelimb grip strength in a mammal, for improving a fine-motor skill in a mammal or for improving a gross-motor skill.
- the invention relates to a method of administering a combination suitable for at least one of said uses, comprising administering an effective amount of according to the invention a combination of a uridine source and an omega-3-polyunsaturated fatty acid having 18-24 carbon atoms to a mammal.
- a mammal is typically in need of treatment because it suffers from a disturbance in coordination of limbs in a mammal, a disturbance in equilibrium in a mammal, a disturbance in limb strength, in particular forelimb grip strength in a mammal, a disturbance in a fine-motor skill in a mammal, or a disturbance in a gross-motor skill, or because the mammal belongs to a risk group for developing such a disturbance.
- risk groups are in particular mammals suffering from a disorder of which any one or more of said disturbances are known symptoms. In particular, mammals suffering from a disorder mentioned in the present description or claims belong to such risk groups.
- a combination of an omega3-PUFA and a uridine source has a positive effect on functioning of a limb. It is considered that the improvement is at least partly due to an improvement in the neurological functioning of the mammal treated with a combination.
- FIG. 1 shows results for Example 1: the average time on rotarod (in seconds) at different times (in days) after intra-striatal injection with vehicle (Veh) or rotenone (Rot). Four groups of mice are shown as explained in Table 1.
- FIG. 2 shows results for Example 5, regarding the time spent by mice on a Rotarod in a therapeutic setting.
- Gross motor skills involve movement of the arms, legs, feet, or entire body. This includes actions such as running, crawling, walking, swimming, and other activities that involve larger muscles.
- Fine motor skills are the small movements that occur in the hands, wrists, fingers, feet, toes, lips and tongue. They are the smaller actions that occur such as picking up objects between the thumb and finger, using a pencil to write carefully, holding a fork and using it to eat, and other small muscle tasks that occur on a daily basis.
- a suitable way to test balancing ability in a mammal (under lab conditions), and thus also to test whether a certain treatment has an effect on a disturbance in equilibrium is a rotarod test, as described in detail in the Examples.

Abstract
Description
- The invention relates to a composition comprising a uridine source, an omega-3 polyunsaturated fatty acid for use in the improvement of a subject's coordination, balance, grip strength or fine motor skills.
- The nervous system, in particular the brain, plays an essential role in a mammal's life. For example cognitive, emotional, social, sensory, motoric and regulatory functions are mainly determined by the brain. In society more and more diseases, disorders and problems with a proper functioning of the brain are becoming recognised. Brain functioning can become impaired, e.g. due to traumata (e.g. accidents, violence), abuse of drugs (e.g. alcohol) or systematic malnourishment. Also during aging several deleterious changes occur in the nervous system and in particular in the brain. Malfunctioning of the brain is therefore especially a problem in the elderly and more in particular in the frail or malnourished elderly. In this group, several diseases and disorders which are associated with or find their cause in a badly functioning nervous system are therefore relatively frequently observed. Examples are several forms of dementia, progressive neurodegenerative disorders, mood disorders but also other diseases or disorders like abnormal behaviour.
- Several nutritional approaches have been proposed in the art to support brain function. For instance, WO 2009/002165 relates to a lipid fraction for the support of brain function. The lipid fraction comprises hexanoic acid and/or octanoic acid, eicosapentaenoic acid, and more than 0.4 g [alpha]-linolenic acid per 100 g fatty acids of the lipid fraction for the support of brain function. Optionally, the lipid fraction is administered in combination with non-lipid ingredients, but the lipid fraction preferably contributes to more than 45 en % of the energy of a ready to consume product. Nucleotides may be added to support brain function. Use of fibres is mentioned in order to reduce gastro-intestinal discomfort or to improve postprandial lipid profile. WO 2009/002165 acknowledges that brain function involves various distinct aspects, such as the cognition, social skills, decision making skills and motoric skills. However, even though motoric skills are mentioned as something in which brain function plays a role, there is no specific disclosure of the use of specific combination of components in order to provide a composition that is particularly useful for improving or maintaining the functioning of mammal's limbs.
- There is a need for specific products which contribute to improve, maintain or at least reduce a decline in the functioning of a mammal's, in particular a human's, limbs.
- The inventors found that a specific combination of components has a positive effect on one or more functions of the limbs in order to improve specific aspects in relation to the functioning of brain functioning, in particular coordination, balance, grip strength, fine motor skills or gross motor skills.
- Accordingly the invention relates to a combination of a uridine source and an omega-3-polyunsaturated fatty acid having 18-24 carbon atoms for at least on use selected from
-
- use in the prevention or treatment of a disturbance in coordination of limbs in a mammal
- use in the prevention or treatment of a disturbance in equilibrium in a mammal
- in the prevention or treatment of a disturbance in limb strength, in particular forelimb grip strength in a mammal
- use in the prevention or treatment of a disturbance in a fine-motor skill in a mammal
- use in the prevention or treatment of a disturbance in a gross-motor skill in a mammal.
- Further, the invention relates to the use of a combination of a uridine source and an omega-3-polyunsaturated fatty acid having 18-24 carbon atoms in the manufacture of a medicament or a preparation for at least one of these uses.
- Further, the invention, relates to a use, in particular a non-medical use of a uridine source and an omega-3-polyunsaturated fatty acid having 18-24 carbon atoms for improving coordination of limbs in a mammal, for improving sense of equilibrium in a mammal, for improving forelimb grip strength in a mammal, for improving a fine-motor skill in a mammal or for improving a gross-motor skill.
- Further, the invention relates to a method of administering a combination suitable for at least one of said uses, comprising administering an effective amount of according to the invention a combination of a uridine source and an omega-3-polyunsaturated fatty acid having 18-24 carbon atoms to a mammal. Such mammal is typically in need of treatment because it suffers from a disturbance in coordination of limbs in a mammal, a disturbance in equilibrium in a mammal, a disturbance in limb strength, in particular forelimb grip strength in a mammal, a disturbance in a fine-motor skill in a mammal, or a disturbance in a gross-motor skill, or because the mammal belongs to a risk group for developing such a disturbance. Such risk groups are in particular mammals suffering from a disorder of which any one or more of said disturbances are known symptoms. In particular, mammals suffering from a disorder mentioned in the present description or claims belong to such risk groups.
- It has surprisingly been found that a combination of an omega3-PUFA and a uridine source, said combination optionally comprising one or more further active ingredients, such as vitamin D or butyrate producing fibre, has a positive effect on functioning of a limb. It is considered that the improvement is at least partly due to an improvement in the neurological functioning of the mammal treated with a combination.

FIG. 1 shows results for Example 1: the average time on rotarod (in seconds) at different times (in days) after intra-striatal injection with vehicle (Veh) or rotenone (Rot). Four groups of mice are shown as explained in Table 1. -
FIG. 2 shows results for Example 5, regarding the time spent by mice on a Rotarod in a therapeutic setting. - Motor skills are movements and actions of the muscles. They are categorized in two groups: gross motor skills and fine motor skills. Gross motor skills involve movement of the arms, legs, feet, or entire body. This includes actions such as running, crawling, walking, swimming, and other activities that involve larger muscles. Fine motor skills are the small movements that occur in the hands, wrists, fingers, feet, toes, lips and tongue. They are the smaller actions that occur such as picking up objects between the thumb and finger, using a pencil to write carefully, holding a fork and using it to eat, and other small muscle tasks that occur on a daily basis.
- A suitable way to test balancing ability in a mammal (under lab conditions), and thus also to test whether a certain treatment has an effect on a disturbance in equilibrium is a rotarod test, as described in detail in the Examples.
- In humans, balance abilities are measured with the Berg Balance Scale (BBS), which is generally considered the gold standard. The BBS is a clinical measure of a person's static and dynamic balance ability. The test takes 15-20 minutes and comprises a set of 14 simple balance related tasks, ranging from standing up from a sitting position, to standing on one foot. The degree of success in achieving each task is given a score of zero (unable) to four (independent), and the final measure is the sum of all of the scores” (http://aahf.info/pdf/Berg Balance Scale.pdf) The BBS is a validated measure to assess balance abilities in neurological disorders such as Parkinson's disease (Qutubuddin et al., Arch Phys Med Rehabil., 2005, April; 85(4):789-92 Other tests include the Tinetti Mobility test, which assess also risk of falls in Parkinson disease (Kegelmeyer et al., 2007, Phys Ther. 87(10):1369-78
- Fine motor skills can be evaluated in humans using a panel equipped with digital timing sensors, collecting information on speed and accuracy during specific dexterity tasks as described in Smith et al., Neurology, 53(7):1458-1458, 1999.
- “Coordination” as used herein generally means “coordination of limbs”. Coordination of limbs can be determined by testing the patient's ability to perform rapidly alternating and point-to-point movements correctly. Point-to-point movements are movements performed with the same index finger to bring from one point to another, for instance from the subject's own nose to the examiner's outstretched finger.
- Strength can be tested with a calibrated strength tester, designed for testing the strength of a specific limb or part thereof.
- “Forelimb grip-strength” can be tested with a calibrated grip strength tester. In a mouse model a grip tester (Panlab, Cornella, Spain) is used by prompting the mouse to grip a trapeze bar with both forelimbs and pulling the mouse by the tail (as proximal to the body as possible) parallel to the orientation of the strain gauge and the trapeze bar. For mean grip strength analyses, a set included five repetitions and relative mean grip strength, i.e. the absolute mean grip strength divided by body weight (grams) was calculated (Leiter et al. 2011) In human, grip strength can be measured with a hand dynamometer.

Suitable derivative forms include esters and ethers, including monoglyceride, diglyceride, triglyceride and phospholipid forms, as known in the art. In particular, good results have been achieved with a triglyceride. When making calculations about amounts, one can assume the same bioavailability as the pure fatty acid and a contribution of fatty acid that is similar to the amount moles of fatty acids in the complete molecule, and correcting for the weight of the complete molecule. Polyunsaturated fatty acids are abbreviated as PUFA's.

- The uridine source typically is selected from uracil, (deoxy)uridine, nucleotides of (deoxy)urdine, cytosine, (deoxy)cytidine, nucleotides of (deoxy)cytidine and derivatives thereof. Dietary cytidine, which is capable of being converted into uridine in humans, is regarded as a source of uridine in the context of the present invention.
- Regarding the derivatives, in particular an amino group attached to the heterocyclic six membered ring may be derivatised or one or more of the hydroxyl groups of the ribose or deoxyribose of the nucleoside or nucleotide may derivatised, preferably esterified (acylated), for instance with a C1-C24 carboxylic acid. Preferred acylated forms of the uridine source are those wherein the (deoxy)ribose has been acylated with acetic acid, n-caproic acid, caprylic acid, or n-capric acid, because these increase the bioavailability of the uridine source. Methods for reacting these medium chain fatty acids to uridines, for example to the 5′ position of the uridine are known in the art per se for other fatty acids and comprise conventional acylation methods. In a further embodiment the uridine source is acylated with a PUFA, for instance an omega-3 PUFA. Thus, in a specific embodiment, the combination for use of the invention comprises the PUFA and the uridine source combined in a single molecule, which may be hydrolysed in vivo. Esters of a uridine/cytidine derivatives and methods for making those are generally known in the art. Such derivatives have amongst others been described in EP 1,390,378 and in U.S. Pat. No. 5,470,838.
- Preferred uridine sources in a combination for use according to the invention the uridine source are selected from the group of uracyl, uridine, deoxyuridine, derivatised uridine, derivatised deoxy uridine, cytosine, (deoxy)cytidine and derivatised cytidines; more preferably a uridine source is selected from the group of uridine, UMP, UDP, UTP, CMP, CDP, CTP dUMP, dUDP, dUTP, dCMP, dCDP and dCTP. Optionally one or more hydroxyl moieties of the (deoxy)ribose of said nucleotide or nucleoside is acylated.
- Particularly preferred is a uridine source selected from the group of uridine UMP, UDP, UTP, dUMP, dUDP, dUTP, wherein optionally the (deoxy)ribose of said nucleotide or nucleoside is acylated.
- In a highly preferred embodiment, the present combination for use according to the invention comprises uridine and/or uridine phosphate.
- Preferably at least 50 wt. % of the uridine source in the combination for use according to the invention is provided by UMP, more preferably at least 75 wt. %, most preferably at least 95 wt. %.
- The present combination for use according to the invention is preferably administered (or is in a format) to provide uridine (the cumulative amount of uridine, deoxyuridine, uridine phosphates, uracil and acylated uridine derivatives) in an amount of 0.08-3 g per day, preferably 0.1-2 g per day, more preferably 0.2-1 g per day.
- The present combination for use according to the invention preferably comprises uridine in an amount of 0.08-3 g UMP per 100 ml of a liquid product, preferably 0.1-2 g UMP per 100 ml of a liquid product, more preferably 0.2-1 g per 100 ml liquid product.
- Preferably 1-37.5 mg UMP per kilogram body weight is administered per day.
- The required dosages of the equivalents on a weight base can be calculated from the dose for UMP by taking equimolar amounts using the molecular weight of the equivalent and of UMP, the latter being (about) 324 Dalton. Accordingly a daily dosage of the uridine source in the range of 3-116 μmol per kg body weight per day is preferred. In a particularly preferred embodiment the daily dosage of uridine source is 10-50 μmol per kg body weight per day. If desired a lower amount or higher amount, e.g. from about 1 to about 150 μmol/kg body weight can be administered.
- In a preferred embodiment, the combination for use according to the invention comprises dietary fibre.
- The fibres may be selected from soluble fibres and insoluble fibres.
- The fibres are generally composed of a plurality of carbohydrate units. The fibres may be short-chain indigestible carbohydrates or long-chain indigestible carbohydrates. Dependent on the type of fibre, national food regulations may have different definitions for what constitute short chain or long chain. As used herein, short chain fibres generally have a polymerization degree of less than 20, in particular of 2-12 less, more in particular 3-9; long chain fibres have a polymerization degree at least one higher than specified for short chain fibres, so 10 or more, 13 or more or 20 or more.
- The inventors surprisingly found that the presence of a specific group of fibres in combination with the omega-3-PUFA and the uridine source has a positive effect on specific body functions wherein the limbs play a role. As illustrated by the Examples, mice treated with a diet containing butyrate producing fibre performed better in a rotarod test than mice treated with a diet without such fibre, indicating improved coordination and/or body balance (equilibrium). From the Examples, the inventors realise that in particular Parkinson patients may benefit from the butyrate producing fibre in combination with the uridine source, omega3-PUFA and optionally one or more other components, such as vitamin D. Without being bound by theory, the inventors contemplate that these fibres produce butyrate which is absorbed by the body and provides a neuroprotective effect relevant to improve coordination or body balance. The inventors further consider that butyrate producing fibre is positive for improving for limp grip strength or a fine motor skill.
- Butyrate producing fibres are indigestible carbohydrates that have butyrate as a breakdown product when fermented by colonic flora. The term ‘butyrate producing fibre’ is used herein in particular for fibre that is capable of producing at least 0.5 mmol or more, preferably at least 0.75 mmol or more, more preferably at least 1.0 mmol or more butyrate/gram fibre after 24 hours of in vitro fermentation. In practice, the maximum amount of butyrate producible under these conditions is usually 5 mmol or less, in particular 3.5 mmol or less, more in particular 2.5 mmol or less butyrate/gram fibre after 24 hours of in vitro fermentation.
- The producible amount of butyrate is determinable using a semi-dynamic colon model (e.g. using a TIM artificial gut system). In an alternative model, fresh faecal samples are collected from healthy adults (without gastrointestinal problems; no use of antibiotics for a last 2 weeks prior to sample taking). Faecal samples are divided in smaller portions and mixed with glycerol (10%) in an anaerobic cabinet and stored at −80° C. In each experiment the faecal samples from all donors are pooled at equal concentrations and mixed together in an anaerobic cabinet, to avoid subject-dependent variation in the adult microbiota as much as possible. The samples are inoculated with a fibre under fermentation conditions and fermentation is allowed to take place. Butyrate production is determined after 24 hrs using GC. In particular
-
- the model makes use of samples from four healthy adults (e.g., three male donors and one female donor) in the age of 19-35 years;
- the fibre is inoculated in a faeces suspension at a content of 200 mg/6 ml faeces suspension
- the faeces suspension is made by mixing aeces with a fermentation medium as 1:5 v/v;
- the fermentation medium: buffered peptone water 3.0 g/1, Yeast Extract 2.5 g/1, Tryptone 3.0 g/1, L-Cysteine-HCl 0.4 g/1, Bile salts 0.05 g/1, K2HPO4.3H2O 2.6 g/1, NaHCO3 0.2 g/1, NaCl 4.5 g/1, MgSO4.7H2O 0.5 g/1, CaCl2. 2H2O 0.3 g/1, FeSO4.7H2O 0.005 g/l. Ingredients can be added one by one in 800 ml water, pH is adjusted to 6.3±0.1 with K2HPO4 or NaHCO3 and volume is filled up to 1 liter. Medium is sterilized for 15 minutes at 121° C.
- The fermentation temperature is 37° C.
- The total dosage of butyrate producing fibre in accordance with the invention preferably is 1 to 15 g per dosage, more preferably of 2 to 10 g per dosage, in particular 3-8 g per dosage. The total butyrate producing fibre content, based on total fibre content in a composition for use in accordance with the invention is up to 100 wt %, in particular 99 wt. % or less, more in particular 95 wt. % or less. The total butyrate producing fibre content, based on total fibre content preferably is at least 50 wt. %, based on total fibre content, preferably at least 70 wt. %, more preferably at least 80 wt. %, in particular 90 wt. % or more.
- Preferably the combination or nutritional composition for use according to the invention comprises fibre in an amount sufficient to produce 0.3-5 mmol, more preferably 0.5-3.5, in particular 0.7-3, more in particular 1.0-2.5 mmol butyrate per gram fibre, under the using a semi-dynamic colon model, described above.
- Preferred soluble butyrate producing fibres include fructooligosaccharides (FOS), galactooligosaccharides (GOS), bran and dextrins (e.g. Nutriose®). These are well soluble and are a suitable substrate for colonic flora to produce butyrate, when fermented. Preferred brans are oat bran, rice bran and wheat bran. In a particularly preferred embodiment, several butyrate producing fibres are used, such as at FOS and a dextrin plus optionally bran and/or GOS; or FOS and bran plus optionally dextrin and/or GOS.

- The invention is now illustrated by the following examples.
- In mice, Parkinson's disease (PD), was induced by intra-striatal injection of 2.7 μg of rotenone by stereotaxic surgery into the brain. Epidemiological studies had previously shown that exposure to this pesticide induced Parkinson's disease (PD). The rotarod treadmill consists of a plastic rod, with a non-slippery surface, above the base (trip plate). Mice were placed on an accelerating rod with speeds starting with 2 rpm and gradually increasing to 20 rpm. The rodent's ability to remain on the rotating rod (time to first fall) was recorded for a maximum of 5 minutes. Before baseline, mice were trained with the rotarod apparatus to rule out learning effects throughout the experiment.
- Four experimental groups of 10 mice each were used which were either injected with rotenone or vehicle and which received control or active diet (=UMP+fish oil) according to Table 1. The specific composition of the control and active diets are presented in Table 2. Dietary intervention was started one week before surgery and was continued for six weeks.
