The Inuit (Eskimo) gene pool is in many respects similar to that of East Asian populations. Some polymorphisms imply frequent occurrence of disorders comparatively rare in Western Europe (e.g. lactose and sucrose malabsorptions). Low frequencies of alleles for slow isoniazid acetylation and sparteine/debrisoquine oxidation indicate slow elimination of a multitude of drugs. Autoimmune disorders (e.g. rheumatoid arthritis, insulin dependent diabetes mellitus, Graves' disease and psoriasis) are rare, possibly explained by the associations of these disorders with HLA-alleles rare in Inuit (e.g. HLA-B8). Correspondingly high incidence of reactive arthritis may be explained by a frequent HLA-B27 allele. Prevalence of disorders due to instability of mesenchymal tissues (e.g. spondylolisthesis, osteoarthrosis, hernia, heart block) are still in want of a biochemical explanation. Attention is drawn to the urgency of genetic studies in the Arctic because of the accelerating hybridization of Inuit in all circumpolar areas.

It is well known that IDDM cases can be complicated with osteopenia, but most of these results were reported using single photon absorptiometry. There have been few reports of diabetic osteopenia using dual energy X-ray absorptiometry (DXA), a method that is excellent for precise bone mineral measurement. Osteoarthritis and osteophytes of unknown origin in the lumbar vertebrae are often observed in elderly NIDDM patients. In this study, we examined the clinical characteristics of decreased bone mineral density (BMD) and whether anteroposterior (AP) scanning of the lumbar vertebrae (L2-L4) provides sufficient informations concerning osteopenia in elderly diabetic patients. The study was performed using DXA, which can quantify regional BMD throughout the body. The BMD in the total body and that in the lumbar vertebrae were measured by DXA (Lunar Co.) in 68 diabetics over age 60, 33 males and 35 females, mean age 68 +/- 8 yr, (mean +/- SD) and in 94 middle-aged diabetics (40 to 59), 56 males and 38 females, mean age 51 +/- 4 yr. The percentage of decrease in regional BMD in diabetic patients differed significantly by age and gender. The BMD in the head and spine especially decreased after menopause in women. However, the BMD of the leg and spine did not decrease with age in men. When the BMD of the lumbar vertebrae was plotted against the Y axis and the BMD in the total body against the X axis, the slope of the curve showed a greater increase in elderly diabetics than that in middle aged diabetics (1.8 vs 1.5) suggesting the BMD in the lumbar vertebrae has been overestimated.(ABSTRACT TRUNCATED AT 250 WORDS)

The quality of life of women with fibromyalgia was explored and compared to the quality of life of women with rheumatoid arthritis, osteoarthritis, permanent ostomies, chronic obstructive pulmonary disease, insulin dependent diabetes, and healthy controls. The women with fibromyalgia consistently scored among the lowest in all domains measured. These results suggest that fibromyalgia may adversely affect quality of life to an extent not previously recognized.

A well-conducted twin study has the potential to evaluate the relative contribution of genetic and environmental factors to a given disease. Many studies are inconclusive because of problems with methodology. This article reviews the principles underlying the classical twin study and then discusses potential pitfalls. Twin studies in three diseases are evaluated, namely, multiple sclerosis, diabetes, osteoarthritis. Studies in multiple sclerosis are thought to be inconclusive. In type 1 diabetes, genetic factors are very important and according to the single study in females with osteoarthritis, genetic factors are also significant.

Interleukin-1 (IL-1) is involved in a broad range of biological activities that affect immunological, inflammatory, and nonimmunological responses. Although the role of the IL-1 proteins in normal physiological responses in vivo remains incompletely defined, there is substantial evidence that excessive production of IL-1 contributes to the pathogenesis of many illnesses with autoimmune or inflammatory components, including rheumatoid and osteoarthritis, type I diabetes mellitus and atherosclerosis. Despite numerous reports on IL-1 regulation, very little is known regarding the molecular details of IL-1 production, particularly at the transcription level. This review will focus on our studies of transcriptional regulation of the murine IL-1beta gene and, where appropriate, comparison to similar studies of the human IL-1beta gene. A basic understanding at this level should lead to effective pharmacological intervention and, ultimately, to control of inflammatory disease.

Leptin is 16 kDa adipokine that links nutritional status with neuroendocrine and immune functions. Initially thought to be a satiety factor that regulates body weight by inhibiting food intake and stimulating energy expenditure, leptin is a pleiotropic hormone whose multiple effects include regulation of endocrine function, reproduction, and immunity. Leptin can be considered as a pro-inflammatory cytokine that belongs to the family of long-chain helical cytokines and has structural similarity with interleukin-6, prolactin, growth hormone, IL-12, IL-15, granulocyte colony-stimulating factor and oncostatin M. Because of its dual nature as a hormone and cytokine, leptin links the neuroendocrine and the immune system. The role of leptin in the modulation of immune response and inflammation has recently become increasingly evident. The increase in leptin production that occurs during infection and inflammation strongly suggests that leptin is a part of the cytokine network which governs the inflammatory-immune response and the host defense mechanisms. Leptin plays an important role in inflammatory processes involving T cells and has been reported to modulate T-helper cells activity in the cellular immune response. Several studies have implicated leptin in the pathogenesis of autoimmune inflammatory conditions, such as experimental autoimmune encephalomyelitis, type 1 diabetes, rheumatoid arthritis, and intestinal inflammation. Very recently, a key role for leptin in osteoarthritis has been demonstrated: leptin indeed exhibits, in concert with other pro-inflammatory cytokines, a detrimental effect on articular cartilage by promoting nitric oxide synthesis in chondrocytes. Here, we review the recent advances regarding leptin biology with a special focus on those actions relevant to the role of leptin in the pathophysiology of inflammatory processes and immune responses.

Considerable knowledge has accumulated in recent decades concerning the significance of physical activity in the treatment of a number of diseases, including diseases that do not primarily manifest as disorders of the locomotive apparatus. In this review we present the evidence for prescribing exercise therapy in the treatment of metabolic syndrome-related disorders (insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity), heart and pulmonary diseases (chronic obstructive pulmonary disease, coronary heart disease, chronic heart failure, intermittent claudication), muscle, bone and joint diseases (osteoarthritis, rheumatoid arthritis, osteoporosis, fibromyalgia, chronic fatigue syndrome) and cancer, depression, asthma and type 1 diabetes. For each disease, we review the effect of exercise therapy on disease pathogenesis, on symptoms specific to the diagnosis, on physical fitness or strength and on quality of life. The possible mechanisms of action are briefly examined and the principles for prescribing exercise therapy are discussed, focusing on the type and amount of exercise and possible contraindications.

Adult stem cells from bone marrow have been used in the treatment of cancer for many years. Recently, however, interest has developed in the isolation and growth of adult, cord and embryonic stem cells for use in regenerative medicine. Their therapeutic use will undoubtedly be implemented in nursing practice in a variety of clinical areas. This article is a brief introduction to stem cells and addresses the biology of these cells and their potential clinical applications, looking at three possible diseases as examples: myocardial infarction, type 1 diabetes and osteoarthritis.

Vitamin D from ultraviolet-B (UVB) irradiance, food, and supplements is receiving increased attention lately for its role in maintaining optimal health. Although the calcemic effects of vitamin D have been known for about a century, the non-calcemic effects have been studied intently only during the past two-three decades. The strongest links to the beneficial roles of UVB and vitamin D to date are for bone and muscle conditions and diseases. There is also a preponderance of evidence from a variety of studies that vitamin D reduces the risk of colon cancer, with 1000 IU/day of vitamin D or serum 25-hydroxyvitamin D levels >33 ng/mL (82 nmol/L) associated with a 50% lower incidence of colorectal cancer. There is also reasonable evidence that vitamin D reduces the risk of breast, lung, ovarian, and prostate cancer and non-Hodgkin's lymphoma. There is weaker, primarily ecologic, evidence for the role of vitamin D in reducing the risk of an additional dozen types of cancer. There is reasonably strong ecologic and case-control evidence that vitamin D reduces the risk of autoimmune diseases including such as multiple sclerosis and type 1 diabetes mellitus, and weaker evidence for rheumatoid arthritis, osteoarthritis, type 2 diabetes mellitus, hypertension and stroke. It is noted that mechanisms whereby vitamin D exerts its effect are generally well understood for the various conditions and diseases discussed here.

Initially described as a satiety factor with neuroendocrine properties, leptin has been shown to regulate immune and inflammatory processes. Mainly produced by white adipose tissue, this hormone was first known to regulate energy homeostasis by inhibiting food intake and by upregulating energy consumption. Leptin is a dual molecule: apart from its actions as a hormone involved in energy homeostasis, increasing evidence suggests that leptin is a novel proinflammatory adipocyte-derived factor that operates in the cytokine network by linking immune and inflammatory processes to the neuroendocrine system. In fact, recent findings have shown that leptin regulates and participates both in immune homeostasis and inflammatory processes not only by acting as a modulator of T-cell activity, but also by playing a key role in a host of autoimmune inflammatory conditions such as autoimmune encephalomyelitis, type 1 diabetes, bowel inflammation and articular degenerative diseases such as osteoarthritis and rheumatoid arthritis. This review will more closely address leptin's cytokine properties rather than its role as a metabolic hormone by focusing on its biological actions in inflammatory processes, specifically those related to degenerative inflammatory diseases of the joints.
