Description

FIELD OF THE INVENTION

The present invention relates to dietary supplements and medical foods for treating fatigue-related syndromes. The compositions of the present invention include rosemary.

BACKGROUND OF THE INVENTION

In 1948, the World Health Organization defined health as not only the absence of disease, but also the presence of physical, mental, and social well-being. (Constitution of the World Health Organization. In: World Health Organization, Handbook of Basic Documents. 5th ed. Geneva: Palais des Nations, 3-20 (1952)). The status of a patient's physical, mental, and social functioning is often referred to in the literature as quality-of-life and is used as a measure of health outcome. In the past 25 years, there has been a nearly exponential increase in the evaluation of quality-of-life as a technique of clinical research as a component of determining clinical benefit from an intervention protocol. For example, in 1973, only five articles listed quality-of-life as a key word in the Medline database, whereas in the subsequent four years there were successively 195,273,490, and 1,252 such articles. (Testa MA and Simonson DC, N Eng J Med. 334:835-840 (1996). In 1998, approximately 3,724 articles listed quality-of-life as a key word. Thus, the health outcome, or quality-of-life, associated with a clinical intervention has been recognized as an important tool in measuring effectiveness and costs of medical care. (Wilson IB and Cleary PD., JAMA., 273:59-65 (1995)).

Extensive research has resulted in the development of instruments that measure health outcome using quality-of-life tools that follow academically well-established and statistically validated psychometric principles. (Ware J E Jr., J Chronic Dis., 40:473-480 (1987); Spilker B., Quality of Life and Pharmacoeconomics in Clinical Trials, 2nd ed. Philadelphia, Pa: Lippincott-Raven Co; 1995.) One such tool is the SF-36 (Short form-36), which has been widely used in clinical trials and in clinical practice to assess health outcome. (Clancy CM and Eisenberg J M, Science, 282:245-246 (1998)). The SF-36 was derived from the Medical Outcomes Study, which involved 11,336 patients from 523 different clinical sites. (Ware J E, Sherbourne C D, Davies A R. Developing and testing the MOS 20-item short-form health survey. In: Stewart AL and Ware J E, eds., Measuring functioning and well-being: The Medical Outcomes Study approach. Durham, N.C.: University Press, 277-290 (1992); Ware J E. SF-36 Health Survey: manual and interpretation guide. Boston, Mass.: Nimrod Press; 2:1-3:22 (1993)). The validity and reliability of the SF-36 has been proven in several studies in which researchers tested internal consistency, within subject reliability, and differentiation between patient populations. (McHorney CA, et al., Medical Care, 31:247-263 (1993); McHorney CA, et al., Medical Care, 30:S253-S265 (1992); Jenkinson C, et al., Br Med J., 306:1436-1440 (1993); Brazier J E, et al., Br Med J. 305:160-164 (1992)). The SF-36 has been shown to predict the course of depression during a two-year study, and to be lower overall in patients who experience chronic health disorders. (Wells K B, et al., Archives General Psychiatry, 49:788-794 (1992); Schlenk E A, et al., Quality of Life Res., 7:57-65 (1998)).

The SF-36 is a 36-item questionnaire that assesses eight dimensions of health outcome: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Results from the questionnaire can be reported as a relative number on a scale of 0 to 100, in which 100 is the highest or most functional and 0 is the most compromised for that category of functioning. A summary of the meaning of high and low scores for each category is shown-in Table 1.

The latter half of the twentieth century has been characterized by an increasing prevalence of chronic disorders. Indeed, seven of the ten leading causes of death in the USA are chronic in nature, accounting for 72% of the deaths from all causes. (National Center for Health Statistics. Health, United States, 1995. Hyattsville, Md.: Public Health Service, 1995.) Chronic disorders such as rheumatic disorders, chronic pain, and fatigue contribute to the 6% of the population that is impaired to some extent in the conduct of major life activities such as work, school, and self-care. (US Department of Health and Human Services, Public Health Service. Healthy People 2000: National Health Promotion and Disease Prevention Objectives. Hyattsville, Md.: Public Health Service; 1991.) Health care use also appears to be substantial for patients with chronic conditions. For example, patients with chronic fatigue syndrome (CFS), fibromyalgia (FM), and multiple chemical sensitivities (MCS) have been shown to visit medical care facilities on average 22.1, 39.7, and 23.3 times per year, respectively. (Buchwald D, Garrity D., Arch Intern Med., 154:2049-2053 (1994)).

In chronic conditions such as rheumatic disorders, fatigue and energy-deficit disorders, and chronic pain, biological and physiological factors have an inconsistent relationship to symptoms. (Wilson IB, Cleary PD., JAMA, 273:59-65 (1995)). Therefore, they are difficult to measure by laboratory values. In fact, in clinical practice, anywhere from 30% to 80% of patients who see a physician may have conditions for which no physiological or organic cause is found after routine investigation. (Wilson IB and Cleary P D, JAMA, 273:59-65 (1995)).

For example, the term fibromyalgia (FM) refers to an illness whose major characteristics are widespread chronic pain and the physical finding of pain in specifically located tender points. (Wolfe F, et al., The American College of Rheumatology 1990 criteria for the classification of fibromyalgia. Arthritis Rheumatology, 33:160-172 (1990)). Fibromyalgia patients also commonly report morning stiffness, fatigue, and sleep disturbances. A patient presenting with fibromyalgia sometimes reports peripheral athralgias, which can be confused with rheumatoid arthritis. (Goldenberg D L., Current Opinions in Rheumatology, 5:199-208 (1993)). However, fibromyalgia is commonly accepted in the field as pain not associated with inflammation nor joint dysfunction, whereas athralgias are considered inflammatory joint disorders.

Another example of a chronic condition is “chronic fatigue syndrome” (CFS). Clinical diagnosis of CFS requires that the patient show evidence of fatigue lasting beyond 6 months, as well as having eight or more of the following minor symptoms: fever, sore throat, myalgia, muscle weakness (which may be exacerbated by exercise), athralgia, lymphadenopathy, sleep disturbance, headaches, acute or subacute onset, and neuropsychological symptoms. (Holmes G P, et al., Ann Intern Med., 108:387-389 (1988)). Other chronic conditions include idiotypic fatigue, myofascial pain syndrome, for which no definition exists, as well as autoimmune disorders, asthma, and gastrointestinal disorders such as irritable bowel syndrome.

In these chronic conditions, pain and fatigue are often suffered over many years without correlation to a diagnosable or definable acute or chronic disease. Therefore, without anatomical or physical correlation, a patient's response to therapy must be monitored by measuring the level of symptoms they report over a period of time. The MOS SF-36 questionnaire is particularly suited to this type of analysis. For example, patients with chronic disorders such as fibromyalgia have been reported to score lower than the norm in several categories of the MOS SF-36, including bodily pain, role-physical, role-emotional, and vitality (Table 2 where numbers in brackets represent standard deviations).

The data presented in Table 2 are from Ware J E., SF-36 Health Survey: manual and interpretation guide. Boston, Mass.: Nimrod Press; 2:1-3:22 (1993); Schlenk EA, et al., Health-related quality of life in chronic disorders: a comparison across-studies using the MOS SF-36, Quality Life Research, 7:57-65 (1998)).

Although similarities in different categories of the MOS can be observed, data from patients who experience chronic conditions suggests that these patients may show higher variability when analyzing individual MOS categories than with the PCS and MCS summary scores. This variability may result from the frequent coexistence of chronic conditions. For example, it has been shown that 70% of patients with fibromyalgia also experience symptoms of irritable bowel syndrome (IBS), whereas only 10% of control patients experience IBS symptoms. (Veale D, et al., Br J Rheumatol., 30:220-222 (1991)). Fibromyalgia patients have also been reported to shown similar symptoms as CFS.

Taking these considerations into accounts, Ware et al. have used principal component analysis on the MOS SF-36 data collected from 2,474 subjects from the U.S. general population to derive summary scores for the eight categories shown above. (Ware J E Jr., Kosinski M, Keller S D. SF-36 Physical & Mental Health Summary Scales: A user's manual. Boston, Mass.: The Health Institute, New England Medical Center; 3:1-4:6 (1994)). The Physical Component Summary (PCS) and Mental Component Summary (MCS) provide two reliable, reproducible scores for the physical and mental health, respectively. The PCS and MCS scores are converted to a scale of 0 to 100, in which 50 is the mean for the U.S. population.

This analysis of the MOS data takes into account the range of symptoms seen with the chronic condition and reduces the variability from individual patient differences. Low scores on the PCS indicate substantial limitations in self care, physical, social, and role activities, severe bodily pain, frequent tiredness, and health generally rated as poor, whereas high scores indicate no physical limitations, high energy level, and health generally rated as excellent. Low scores on the MCS indicate frequent psychological distress, substantial social and role disability due to emotional problems, and/or health generally rated as poor, whereas high scores indicate frequent positive affect and absence of psychological distress and limitations in usual social and role activities. Table 3 shows relative PCS and MCS scores for various chronic health conditions as compared to U.S. population normative data. Standard deviation is abbreviated as S.D.

It has been the experience of the present inventors that many patients with fatigue-related syndromes, such as fibromyalgia, respond with only moderate improvement to dietary programs. Further, this response has been variable, with a large percentage of patients with fatigue-related syndromes not responding to dietary changes at all. Pharmaceutical approaches, such as non-steroidal anti-inflammatories or anti-depressants have been investigated for fibromyalgia with moderate but variable response. In particular, research on the use of anti-inflammatories to treat fatigue-related syndromes has not shown significant improvement above placebo.

Consequently, there is a need for a dietary supplement and/or medical food that ameliorates at least one of the symptoms, preferably all of the symptoms of a fatigue-related syndrome, such as fibromyalgia, idiotypic fatigue, multiple chemical sensitivity and chronic fatigue syndrome, by way of example. In particular, there is a need for a dietary supplement and/or medical food that improves both the physical and mental functioning of a person suffering from a fatigue-related syndrome.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention provides dietary supplements, medical foods and methods effective to ameliorate at least one of the symptoms of a fatigue-related syndrome. Preferred dietary supplements and medical foods of the present invention improve both the physical and mental functioning of a person suffering from a fatigue-related syndrome. As used herein, the term “fatigue-related syndrome” refers to a medical condition characterized by chronic fatigue. Typically, a person suffering from a fatigue-related syndrome exhibits other symptoms in addition to chronic fatigue, such as non-specific joint pain, muscle pain, headache, sleep disturbance, low-grade fever, lymphadenopathy, post-exertional fatigue, pharyngitis, impaired memory or concentration, and muscle weakness. As the term is used herein, a “fatigue-related syndrome” does not include inflammation as a predominant symptom. By way of non-limiting example, the term “fatigue-related syndrome” includes idiotypic fatigue, fibromyalgia, multiple chemical sensitivity and chronic fatigue syndrome. Presently preferred dietary supplements, medical foods and methods of the present invention are especially effective when used to treat fibromyalgia.

The compositions of the present invention include rosemary, curcumin (always present in the dietary supplements, optionally present in the medical foods) and at least one component selected from the group consisting of quercetin and rutin. Preferably rosemary is utilized as an extract of ground rosemary leaves; curcumin is utilized as a tumeric extract in powder form; quercetin is utilized as either pure quercetin or as a quercetin glycoside (e.g., rutin). The compositions of the present invention may preferably include ginger, limonene and hesperidin. Ginger is preferably utilized as a concentrate of a ginger root extract. Any pure, or substantially pure, form of limonene or hesperidin is useful in the compositions of the present invention.

Rosemary contains the flavonoids carnosol, carnosic acid, rosmanol and ursolic acid and the compositions of the present invention can be supplemented with one or more of the foregoing flavonoids. Ginger contains 6-gingerol, zingerone and 6-shogaol. The compositions of the present invention can be supplemented with one or more of the foregoing ginger components.

The medical foods of the present invention include a protein source, preferably hypoallergenic rice protein extract, suitably prepared as described in U.S. Pat. No. 4,876,096, incorporated herein by reference. The hypoallergenic rice protein extract is preferably fortified with at least one of the following amino acids: L-lysine, L-threonine and L-cysteine. In a presently preferred embodiment, the medical foods of the present invention are fortified with L-lysine and L-threonine in amounts of 6.3% and 0.28% of the weight of rice protein, respectively.

Both the dietary supplements and medical foods of the present invention are preferably used in powder form which can be dissolved in a liquid suitable for human consumption, such as water or a fruit juice. The dietary supplements and medical foods of the present invention can, however, be utilized in any suitable form, such as a solid bar, as a paste, gel, tablet, capsule or liquid.

Typically, the dietary supplements and medical foods of the present invention are preferably administered two times per day, preferably once in the morning and once in the afternoon. A typical treatment regime for the dietary supplements or medical foods will continue for four to eight weeks. Depending on such factors as the medical condition being treated and the response of the patient, the treatment regime may be extended. A medical food of the present invention will typically be consumed in two servings per day as either a meal replacement or as a snack between meals. A serving size for a medical food of the present invention will preferably be in the range of from about 45 grams to about 60 grams and will provide from about 180 calories to about 220 calories to the consumer. In a presently preferred treatment regime a person in need of treatment is provided with two servings of a medical food of the present invention per day. A presently preferred serving size is about 52 grams of powdered medical food which delivers about 200 calories to the consumer.

Suitable ranges for each component preferably included in a medical food in accordance with the present invention are set forth in Table 4 of Example 1. For a dietary supplement compounded in accordance with the present invention, the same ranges of specific ingredients to be included(e.g. Rosemary, Curcurmin, Quercetin, etc.) are utilized. The following examples merely illustrate a preferred embodiment now contemplated for practicing the invention, but should not be construed to limit the invention.

EXAMPLE 1

Improvement in PCS and MCS Components of the MOS SF-36 in Patients Treated with a Preferred Medical Food of the Present Invention

Control Subjects: Sixteen subjects were included in the control, no-intervention study. These subjects were asked to complete a MOS questionnaire at the beginning of the study, and subsequently after an interval of between 1 to 15 weeks. Subjects were told to maintain their routines of diet, medication, and lifestyle and make no intentional changes in the intervening time. The control subjects varied in age from 39 to 61 years, with an average age of 49±7 years, and included 4 men and 12 women.

Subjects with fatigue-related syndromes: Five patients with primary symptoms relating to fatigue were evaluated with the intervention protocol for response. Subjects varied in age from 35 to 61 years, with an average age of 46±10 years, and included two men and three women.

Intervention Protocol: Control subjects received no intervention. Nutritional intervention for the subjects with fatigue-related syndromes involved supplementation of the daily diet with a presently preferred medical food of the invention described in Table 4 (Composition 1). Composition 1 was manufactured as a powdered drink mix, which was prepared by each subject at the time of use by mixing the appropriate amount of the composition in either water or a juice of the subject's choosing. Composition 1 was delivered in two servings per day of 52-gram size, which delivered 400 calories per day to the diet.

Intervention Protocol with Clinical Assessment: Subjects on the intervention protocols were provided with Composition 1 in a powdered form and a dietary protocol. The dietary changes prescribed in the dietary protocol consisted of a modified elimination diet, which is described as a diet free of substances known to produce allergenic responses and is preferably vegetarian. Subjects were instructed to make no changes in supplementation, medication, or exercise routine during the course of the intervention. Medications consumed by the subjects were documented at each office visit. Likewise, compliance to the protocol during the previous weeks was documented by questionnaire during the office visit.

Subjects were maintained on the protocol for between four and nine weeks. Subjects were evaluated by the MOS SF-36 questionnaire, a condition-specific questionnaire when appropriate, and a questionnaire to evaluate general physical symptoms called the Medical Symptoms Questionnaire (MSQ), described in Bland, J. S., and Bralley, J. A., Journal of Applied Nutrition 44: 2-15 (1992). Data were analyzed by standard statistical methods.

EXAMPLE 2

Improvement in the MCS and PCS Scores of Fibromyalgia Patients Treated with a Presently Preferred Medical Food of the Invention

Trial Subjects: Twenty-six subjects were selected on the basis of past diagnosis of fibromyalgia, presentation with chronic musculoskeletal pain of greater than six months duration, and reports of unrestorative or disturbed sleep as assessed by a symptoms questionnaire. Subjects were female with an average age of 47 years, and a range in age of 29 to 65 years. The majority of subjects reported experiencing fibromyalgia symptoms for more than five years, and all subjects reported experiencing symptoms for at least 1-2 years.

Intervention Protocol: Nutritional intervention involved the supplementation of daily diets with one of three different nutritional compositions for a six week period. The amount of nutrients delivered each day by the nutritional compositions is indicated in Table 9. Nutritional compositions were manufactured as a powder drink mix which was prepared by each subject at the time of use. Nutritional compositions were prepared by mixing the appropriate amount of the composition in either water or a juice of the subject's choosing. Composition 1 (a presently preferred medical food of the present invention) was delivered in two 52 gram servings per day for a total of 400 calories per day. Compositions 2 and 3 were each delivered in three 44 gram servings per day for a total of 480 calories per day. Subjects were randomized by trial entry date to one of four different intervention protocols:

The four intervention protocols were: Protocol 1: Composition 1 with no other dietary changes; Protocol 2: Composition 1 with dietary changes; Protocol 3: Composition 2 with dietary changes; Protocol 4: Composition 3 with dietary changes.

Dietary changes consisted of a modified elimination diet, which is a diet free of substances known to produce allergenic responses and is preferably vegetarian. Subjects were instructed to make no changes in their supplementation or medication or exercise routine during the study. Medications consumed by the subjects were documented at each office visit. Likewise, compliance with the protocol during the previous weeks was documented by questionnaire during the office visit.

Clinical Assessment: Subjects were evaluated initially, then at three weeks and at six to eight weeks by questionnaire, documentation of tender points, and grip strength test. Questionnaires included the MOS SF-36 questionnaire, a condition-specific questionnaire, which evaluated sleep patterns, perceived pain and functioning, medication use, and compliance to the protocol, and the Medical Symptoms Questionnaire (MSQ) which evaluated general physical symptoms. Data were analyzed by standard statistical methods. In Tables 10-16, “before intervention” means at the beginning of the trial, and “after intervention” means after six to eight weeks of treatment.

Table 15 sets forth a summary of tender points in fibromyalgia patients before and after nutritional intervention with compositions 1, 2, and 3. The population of fibromyalgia patients treated with Composition 1 included a group of patients who had no other dietary changes, and a group of patients who had other dietary changes. Fisher's Exact test was applied to the two groups (with and without dietary changes) and no significant difference was observed between the two groups. Consequently, the data from the two groups was pooled for subsequent analysis as set forth in Tables 15-17.

Table 17 sets forth the results of a medical symptoms questionnaire (MSQ) in fibromyalgia patients before and after nutritional intervention with compositions 1, 2, and 3. In contrast to the MOS SF-36, in which a higher number indicates a healthier subject, a higher number in the MSQ indicates the presence of a higher number and/or intensity of symptoms. Consequently, a lower MSQ score indicates a healthier subject.

Composition 1 resulted in significant improvement in the MCS section of the MOS SF-36 in fibromyalgia patients. This result indicates improved clinical outcome with respect to mental well-being. The improvement in mental well-being observed with Composition 1 was not dependent on whether dietary changes accompanied the nutrient supplementation protocol, since both groups who received Composition 1, those who made dietary changes and those who did not, showed significant improvement.

Composition 1 also resulted in substantial improvement in physical functioning as observed by decreased tender point index, improved grip strength, and decreased symptoms index on the MSQ. Furthermore, improvement in physical parameters was also seen with Composition 1, in particular with Composition 1 when no dietary intervention was included in the protocol. Compositions 2 and 3 did not result in similar improvements.

While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
