Summary Cardiovascular disease is so prevalent that even those ages six to medicine man dr dre generic paroxetine 30 mg line 30 will have already developed it in its early stages medicine vile order paroxetine 20mg visa. The current standard treatment in medicine can save your life from an impending heart attack in the emergency room treatment 0f gout generic paroxetine 20 mg mastercard. By noting any and all risk factors, one may effectively prevent heart attack and stroke in most all cases. The underlying inflam mation of the artery endothelium is where all the risk factors influence to some degree. The most impact in your life on heart and blood vessel health will be seen when you decide to get serious about living the true health lifestyle.

Gold therapy occasionally causes autoimmune haemolytic anaemia (Hunziker medicine logo buy paroxetine with visa, 1978) medications made from plants purchase generic paroxetine canada, autoimmune thrombocytopenia (Kotsy et al medicine online purchase paroxetine on line amex. Early studies showed that injections of gold thiomalate caused renal lesions, immune complex nephropathy, and proteinuria in Wistar rats (Nagi et al. The histology of these lesions can be characterized as either interstitial nephritis or glomerulonephritis, with specific diagnosis dependent on the presence of specific autoantibodies. Recent works using inbred animals have provided additional information on the pathogenesis of gold-induced renal autoimmunity. These findings indicate that gold compounds appear to cause polyclonal B cell activation to induce a variety of autoantibodies, but detailed mechanisms have not been established. The main difference between classical low molecular weight pharmaceuticals and biopharmaceuticals is that biopharmaceuticals are large molecules that can be recognized directly by the immune system, without the need of metabolism or haptenation. Indeed, it has become clear that nearly all biopharmaceuticals induce anti bodies, although many are of human origin and thus immunolog ically tolerated (Schellekens, 2003). The formed antibodies may have no effect at all or are neutralizing, but occasionally adverse reactions may occur. For instance, erythropoietin has been shown to induce autoimmune anaemia in macaques (Chenuaud et al. Treatments with recombinant therapeutic cytokines occasionally induce autoimmune phenomena. Identified risk factors included the female sex, presence of pre-existing autoimmune thyroiditis, the treated disease. However, the immune effects described for diethylstilbestrol depend largely on the age of the animals at treatment, exposure to diethylstilbestrol, and sex. Short-term exposure of mice to diethylstilbestrol has been described as inducing differential immunological effects, depending upon the dose of hormone and sex (Calemine et al. Aged mice appear especially sensitive to diethylstilbestrol treatment, as highly significant alterations were seen in the thymus and bone marrow of aged 21-month-old mice exposed subacutely to diethyl stilbestrol. Severe thymic hypocellularity develops in treated mice following five consecutive days of intraperitoneal injection with diethylstilbestrol. In the same study, the levels of serum IgG and IgM antibodies to cardiolipin showed age dependent fluctuations but were similar in controls and diethylstil bestrol-treated females; however, the IgG antibodies in diethylstil bestrol-treated females were qualitatively different from those in controls with respect to sensitivity to bovine serum (a source of? In contrast to the situation with females, diethylstilbestrol-treated males had higher levels of these antibodies than controls (Forsberg, 2000). A potential role of diethylstilbestrol in autoimmunity is also demonstrated by enhanced autoantibody production both in vitro and in vivo. Plaque forming cells producing autoantibodies specific for bromelain treated red blood cells were significantly increased in mice implanted with diethylstilbestrol. IgM antibody production by B1 cells in vitro was also enhanced by diethylstilbestrol treatment. The authors suggested that diethylstilbestrol modulates autoantibody production by B1 cells and may be an etiologic factor in the development of autoimmune diseases (Yurino et al. A number of studies have also demon strated that perinatal exposure to diethylstilbestrol in mice produces profound thymus atrophy; although a direct cause?effect relationship has not been established, this has the potential to influence negative selection processes and subsequently influence autoimmune dis eases. In a follow-up study, using two different groups of diethylstilbestrol-exposed women and an appro priate control group for each, no differences in the prevalence or serum titre of antibodies to five common viral diseases and six less common ones were observed. However, an increased prevalence was found in diethylstilbestrol-exposed women of a relatively rare immunological hyperreactivity, rheumatic fever, subsequent to microbial infection (strep throat) (Blair et al. In a further study (Blair, 1992), sera of diethylstilbestrol-exposed and non exposed women were examined for the presence of factors associ ated with autoimmune diseases. The study demonstrated that the incidence of high antibody titres to red blood cell antigen was higher in the diethyl stilbestrol-exposed females than in the controls. Blair (1992) concluded that, in general, humans exposed prenatally to diethylstilbestrol do not exhibit severe defects in basic immune function, but their propensity to develop autoimmune disease and other diseases associated with defects in immune regulation is increased. There are relatively few data pertaining to risk of specific autoimmune diseases in relation to in utero diethylstilbestrol expo sure, although some studies suggest an increased rate of respiratory tract infections, other infectious diseases, or allergies (Noller et al. However, in a follow-up study of the children born as part of a randomized clinical trial that had been conducted in the 1950s, there was little difference in the rates of reported symptoms or specific diagnoses of infectious, allergic, or autoimmune conditions in diethylstilbestrol exposed individuals (253 sons and 296 daughters) compared with the controls (241 sons, 246 daughters) (Baird et al. Even with this sample size, however, the statistical power to assess the risk of specific autoimmune diseases was very limited.

In Europeans and Asians symptoms 24 order 30mg paroxetine with amex, Lp(a) concentrations are highly skewed with a tail toward higher concentrations (Figure 2 treatment tmj order discount paroxetine on-line, top panel) bad medicine order paroxetine 20mg, and in the Copenhagen General 6 Population Study we have observed concentrations as high as 387 mg/dL. Concentrations of other lipoproteins are often affected by life-style and physiological factors, whereas Lp(a) concentrations remain stable inter individually throughout life, indirectly suggesting that Lp(a) concentrations are mostly genetically determined. In very early studies, Lp(a) was suggested to be an inherited trait with autosomal dominant inheritance(2;3;75 77) and a major gene and polygenic factors were proposed as contributors to the variation in Lp(a) concentrations(78-80). Hasstedt and colleagues found that the major gene and the polygenic factors accounted for 95% of the variation in plasma Lp(a) concentrations(78). However, the correlation between the apo(a) size polymorphism and Lp(a) plasma concentrations was found to vary greatly among individuals of different ethnicity, as does plasma Lp(a) concentrations(69;70;73;74;88). One study found that the apo(a) allele frequencies were different among different populations(69). In that study, the size variation of apo(a) explained from 19% in Sudanese to 77% in Malays of the variability in plasma Lp(a) concentrations. However, although genotyping of this variant can be done in large-scale-studies, it requires at present quantitative polymerase chain reaction(6) or even more complicated techniques(39). In other words, these data indirectly suggest that lowering of Lp(a) pharmacologically is unlikely to lead to increased risk of diabetes. Importantly however, more evidence using even better genetic instruments is needed before this can be concluded definitively(67;97). Genetic studies to infer causality: the Mendelian randomization approach Genetic studies, like randomized intervention trials, are completely free of reverse causation and largely free of confounding. Therefore, if a genetic variant or a drug leads to higher or lower concentrations of a lipoprotein and this further leads to higher or lower risk of cardiovascular disease, then it is quite likely that it is the lipoprotein that causes the effect on cardiovascular disease. In contrast, results from observational epidemiology can mislead through confounding and reverse causation. Confounding is if a third factor influences both lipoprotein concentrations and cardiovascular disease risk, while reverse causation implies that cardiovascular disease leads to changes in lipoprotein concentrations, rather than vise versa. There are several early examples of studies that suggest the idea that if a risk factor is elevated or reduced due to genetic variation, and if such genetic variation is or is not associated with a disease of interest, then it would be possible to infer or exclude causality of the risk factor(98-100). This idea involving the causal genetic influence of high Lp(a) concentrations on risk of coronary heart disease was already presented in 1992 by Gerd Utermann and colleagues(101;102). Growing out of the awareness of the limitations of observational epidemiology, it was suggested that Mendelian randomization, that is, the random assortment of genes from 9 parents to offspring that occurs during gamete formation and conception, would provide a method for assessing the causal nature of risk factors on disease. The clear formulation of these ideas has substantially influenced thinking on how to understand disease causality, especially in cardiovascular medicine and most importantly for the role of Lp(a) as a cause of cardiovascular disease. Epidemiology alone cannot determine causality, due to potential problems with confounding and reverse causation (Figure 4, double-pointed arrow #1). Thus, potential confounders including life-style factors may be unevenly distributed between those with high and low Lp(a) concentrations, and such confounders may be the real explanation for the high risk of cardiovascular disease in those with high Lp(a) (Figure 5, left panel). In contrast, in the Mendelian randomization study design such confounders are always evenly distributed between those with high and low Lp(a), and therefore, cannot explain the high cardiovascular risk in those with genetically high Lp(a) concentrations (Figure 5, middle and left panels). The other major potential limitation of observational studies is reverse causation, that is, the possibility that cardiovascular disease leads to high Lp(a) concentrations, rather than vice versa (Figure 5, left panel). In the Mendelian randomization study design, reverse causation is simply not possible, as cardiovascular disease cannot change your genes (Figure 5, middle and left panels). In other words, the Mendelian randomization study design can be used to infer causality just like a randomized, double-blind, placebo-controlled Lp(a) reducing trial and these two types of studies share many advantages and have similar limitations (see Figure 5 in reference(65)). Unfortunately however, so far no randomized, double-blind, placebo-controlled Lp(a) reducing trials to prevent cardiovascular disease have been published or even initiated. Therefore, for now the human evidence to suggest that high Lp(a) causes cardiovascular disease has to depend on genetics and the Mendelian randomization approach. While these approaches are powerful, it is naturally the totality of evidence that counts in understanding causality. Another limitation of observational studies is the problem of regression dilution bias(109;110) because risk factors typically are only measured once, and therefore the association observed will only represent a single point estimate (Figure 5, left panel). Regression dilution bias means that the effect size of the risk estimate is 10 underestimated, although this bias does not influence statistical significance.
