Para se verificar o efeito de drogas hipolipemizantes sobre a qualidade do ovo, desempenho das aves, níveis de Iípides plasmáticos e colesterol na gema do ovo, foram realizados dois experimentos utilizando-se galinhas poedeiras Shaver. No experimento 1, 240 aves com 30 semanas de idade, foram alimentadas durante 12 semanas com dieta comercial (CON1) acrescida de Probucol a 0,1% (PROB), Gemfibrozil a 0,025% (GEMF) e Lovastatina em três concentrações: 0,0005% (LOV1), 0,001% (LOV2) e 0,0015% (LOV3), totalizando seis tratamentos. No experimento 2, 128 aves com 26 semanas de idade, receberam como alimentação, durante seis semanas, dieta formulada sem ingredientes de origem animal (CON2), acrescida de Colestiramina a 0,2% (COL 1) e 0,3% (COL2) e Lovastatina a 0,005% (LOV4), perfazendo um total de quatro tratamentos. Em ambos os experimentos, a adição das drogas não prejudicou a qualidade da casca e do albúmen dos ovos e, de um modo geral, não determinou efeitos indesejáveis sobre o desempenho produtivo das aves, com exceção da redução observada no peso médio dos ovos no experimento 2. No experimento 1, em relação aos lípides plasmáticos, a adição de drogas à ração determinou reduções de significado estatístico (p<0,05), nos triglicérides, apenas no LOV2 (38,5%), e no colesterol total, nos grupos LOV2 (36,0%), LOV3 (36,8%), PROB (29,6%) e GEMF (30,4%). Não foram consignadas alterações significativas nos níveis de HDL-colesterol em relação ao CON 1, observando-se, com exceção do GEMF, tendência a elevação de seus valores com o uso das diferentes drogas. Verificou-se redução significativa (p<0,05) do colesterol na gema (mg/g) nos grupos LOV1 (7,4%) e LOV3 (12,1%). No experimento 2, os lípides plasmáticos não sofreram alterações de significado estatístico em relação ao CON2, sendo que os triglicérides e o colesterol total mostraram tendência a diminuição no LOV4. A concentração de colesterol na gema (mg/g) permaneceu inalterada, em cotejo com o CON2, mediante a adição das drogas utilizadas no experimento 2. Os efeitos da Lovastatina sobre as concentrações de Iípides sanguíneos e de colesterol do ovo foram menos evidentes no experimento 2, onde as aves apresentavam níveis de Iípides plasmáticos mais reduzidos. Os coeficientes de correlação e as equações de regressão calculados mostraram que o peso da gema aumenta conforme o peso do ovo se eleva (p<0,05), e que um aumento do peso da gema corresponde a um incremento de seu teor de colesterol, indicando que as variações dos níveis de colesterol por gema podem ser, em parte, justificadas pelas diferenças entre os pesos dos ovos. / Two experiments were carried out to evaluate the effect of lipid¬lowering agents upon egg quality, reproductive performance, plasma lipids and egg yolk cholesterol levels of Shaver laying hens. In the first trial, two hundred and forty 30-week-old hens were fed basal diet (commercial ration - CON1) supplemented with 0.1 % Probucol (PROB), 0.025% Gemfibrozil (GEMF), or Lovastatin at 0.0005% (LOV1), 0.001 % (LOV2) and 0.015% (LOV3) for a 12-week experimental period. In experiment 2, one hundred and twenty-eight 26-week-old hens were fed basal diet without animal products (CON2) containing either 0.2% Cholestyramine (CaL 1), 0.3% Cholestyramine (COL2) or 0.005% Lovastatin (LOV4) for a period of six weeks. At the termination of both experiments, it was observed that the supplement of the drugs did not impair albumen and shell quality. In addition, hen performance was not adversely affected, with the exception of the significant reduction (p<0.05) in egg weights observed in experiment 2. In experiment 1, with regard to the plasma lipids, the depression in triglyceride concentrations approached statistical significance (p<0.05) only in LOV2 (38.5%), and total cholesterol was significantly depressed (p<0.05) in LOV2 (36.0%), LOV3 (36.8%), PROB (29.6%) and GEMF (30.4%) groups. HOL-cholesterol levels were not significantly altered by drug treatments; but with the exception of GEMF, there was a trend towards the elevation by the use of other drugs. Egg cholesterol content, expressed per gram of yolk was significantly lowered (p<0.05) in LOV1 (7.4%) and LOV3 (12.1 %). In experiment 2, no significant changes were observed on plasma lipids due to the addition of the drugs, but cholesterol and triglyceride levels tend to reduction in LOV4 group. Egg yolk cholesterol remained unchanged in experiment 2 with the supplement of the drugs. The effect of Lovastatin on plasma lipid and egg yolk cholesterol concentration was less remarkable in experiment 2, when hens presented lower plasma lipid levels. When correlation coefficients and regression equations were calculated, it was found that yolk weight increased linearly (p<0.05) as egg weight raised, and the higher the yolk weight, the higher the yolk cholesterol content, indicating that yolk cholesterol content changes may be partially explained by differences among egg weights.

No presente estudo foram avaliados o perfil lipídico, inflamatório e expressão gênica antes e após cada fase de tratamento de indivíduos hipercolesterolêmicos (HC) com (n=47) e sem (n=37) DM2, e 36 normolipidêmicos (NL). No grupo DM2, foi avaliado o perfil glicêmico. O grupo HC foi orientado a fazer dieta e a não utilizar hipolipemiantes por 4 semanas (fase basal, B), a seguir, tratados com ezetimiba (E: 10mg/d/4sem), sinvastatina (S: 10mg/d/8sem) e sinvastatina e ezetimiba (SE: 10mg cada/d/4sem). O grupo DM2 foi tratado com S (10 ou 20mg/d/4sem) e SE. No plasma foi quantificado, TNF-&#945;, IL1&#946;, IL-6, IL-8, MMP9, MCP1, sICAM1, sVCAM1, e-selectina, leptina, PAI-1, resistina e adiponectina e PCRus. A expressão de mRNA de TNFA, MMP9, MCP1, IL6, IL1B, ICAM1, VCAM1, PAI1, LEP, RETN, ADIPOR1 e ADIPOR2 foi quantificada em células mononucleares por PCR em tempo real. No grupo HC, o colesterol total, LDL-c e apoB foram reduzidos em todas as fases, em comparação com o B (p<0,05). No grupo DM2, o tratamento com SE reduziu o colesterol total, LDL-c e apoB em comparação com S (p<0,05), o perfil glicêmico não foi alterado. No grupo HC, SE reduziu a concentração plasmática de adiponectina quando comparado com as outras fases (p<0,001). A expressão de IL6 foi maior no grupo HC que no grupo NL, e, ao contrário, a expressão de IL1B foi maior no grupo NL (p<0,05). A expressão de IL6 foi maior no tratamento S do grupo com maior resposta de LDL-c (tercil T3>50%, p=0,044) em comparação com o grupo com menor resposta (tercil T1<42%). No grupo DM2, PCRus, sICAM-1 e e-selectina foram reduzidos e sVCAM-1 aumentado, pelo tratamento SE (p<0,05). A expressão de MMP9 foi diminuída na fase SE (p<0,05). PAI1, ICAM1, RETN e ADIPOR1 tiveram maior, e IL6 menor, expressão no grupo que utilizou 20mg que no grupo de 10mg de sinvastatina (p<0,05). Observou-se também que o grupo com maior resposta (T3: redução de LDL-c>30%) teve menor expressão de LEP e ADIPOR1 na fase S, comparado com o grupo com menor resposta (T1: redução de LDL-c<20%) (p<0,05). A expressão de PAI1, VCAM1, RETN LEP, ADIPOR1 e ADIPOR2 foi maior nas fases S e SE, no grupo DM2 que no grupo HC (p<0,05). Em conclusão, a expressão de IL6 é maior em dislipidêmicos, e de IL1B maior em normolipidêmicos. A sinvastatina reduz a expressão de IL6 e a concentração de adiponectina em dislipidêmicos. Em diabéticos, a ezetimiba reduz a concentração de PCRus, sICAM-1 e e-selectina, e a expressão de MMP9, ADIPOR1 e LEP. Diabéticos tem maior expressão de PAI1, VCAM1, RETN, LEP, ADIPOR1 e ADIPOR2 que dislipidêmicos. / We evaluated lipid, inflammatory profiles, and gene expression before and after each treatment of hypercholesterolemic subjects (HC) with (n=47) and without (n=37) T2DM and 36 normolipidemics (NL). The glycemic profile was evaluated in T2DM group. The HC group had a low fat diet, without lowering-cholesterol drugs during four weeks (baseline). Afterwards, this group was treated with ezetimibe (E: 10mg/day/4weeks), sinvastatin (S: 10 mg/day/8weeks), and combined E and S (SE: 10mg each/day/4weeks). The T2DM group was treated with S (10 or 20mg/day/4weeks) and SE. Plasma levels of TNF-&#945;, IL1&#946;, IL-6, IL-8, MMP9, MCP1, sICAM1, sVCAM1, e-selectin, leptin, PAI-1, resistin and adiponectin and hsCRP were measured. TNFA, MMP9, MCP1, IL6, IL1B, ICAM1, VCAM1, PAI1, LEP, RETN, ADIPOR1 e ADIPOR2 mRNA expression in mononuclear cells were quantified by real time PCR. In the HC group, total cholesterol, LDL-C and apoB were reduced in all stages, compared with baseline (p<0.05). In T2DM group, SE treatment reduced total cholesterol, LDL-C and apoB compared with S (p<0.05), glycemic profile was not changed. In HC group, SE reduced plasma adiponectin compared to the other phases (p<0.001). IL6 expression was higher in HC group, and instead, IL1B expression was higher in NL group (p<0.05). IL6 expression was higher in S with higher LDL-c lowering group (tertile T3>50%, p = 0.044) compared with the lower LDL-c lowering group (tertile T1<42%). In the group DM2, hsCRP, sICAM and e-selectin were reduced and sVCAM increased by treatment SE (p<0.05). MMP9 expression was reduced in the SE (p<0.05). PAI1, ICAM1, RETN, ADIPOR1 and ADIPOR2 had higher, and IL6 lower, expression in the 20mg simvastatin group than 10mg group (p <0.05). It was also observed that the higher LDL-c lowering group (T3: reduction of LDL-C>30%) had lower LEP and ADIPOR1 expression in S phase, compared with the lower LDL-c lowering group (T1: reduction of LDL-C<20%) (p <0.05). PAI1, VCAM1, RETN LEP, ADIPOR1 and ADIPOR2 expression was higher in S and SE in T2DM group than in the HC group (p<0.05). In conclusion, IL6 expression is increased and IL1B decreased in dyslipidemia. Simvastatin reduces IL6 expression and adiponectin levels in dyslipidemic. In T2DM, ezetimibe reduces hsCRP, sICAM-1 and E-selectin levels and MMP9, ADIPOR1 and LEP expression. T2DM have higher PAI1, VCAM1, RETN, LEP, ADIPOR1 and ADIPOR2 expression of than dyslipidemics.

Background and aims. In patients consulting for chest pain, it is of great importance to evaluate the possibility of ischemic heart disease (IHD). The aims in this thesis were to investigate the accuracy of the general practitioners’ clinical assessments and the applicability of exercise testing and myocardial perfusion scintigraphy (MPS) in patients consulting for chest pain in primary care. Statins are known to prevent IHD. A further aim was therefore to investigate if a relation could be detected on a population basis between the use of statins and the morbidity of acute myocardial infarction (AMI). Methods. All patients from 20 to 79 years, consulting for a new episode of chest pain in three primary health care centres, were included during almost two years from 1998 to 2000. The patients were managed according to the clinical evaluation. The presence of IHD was excluded either by clinical examination only, or if stable IHD was in question, by exercise testing and if the exercise test was inconclusive by an additional MPS. If unstable IHD or myocardial infarction was suspected, referral for emergency hospital examination was made. Correlations between statin sales and the morbidity of AMI in Sweden’s municipalities were analysed in an ecological, register based study. Adjustment was made for sales of antidiabetics, socio-economic deprivation indexes and geographic coordinates. Results. Consultations for chest pain represented 1.5% of all consultations in the ages 20 to 79 and were made by 554 patients. In 281 patients IHD was excluded by clinical examination only. In 208 patients stable IHD and in 65 unstable IHD was in question. Four patients (1.4%) evaluated as not having IHD, were diagnosed with angina pectoris or AMI within three months. Exercise testing was performed in 191 patients and revealed no IHD in 134 and IHD in 14 patients. In 43 patients the exercise test results were equivocal. Thirty-nine of these patients underwent MPS, which showed no IHD in 20 and IHD in 19 of the patients. In a follow up almost six years later, neither mortality rate nor prevalence of IHD differed significantly between the 384 study patients evaluated not to have IHD and the population controls. Statin sales and AMI-incidence or mortality showed no strong associations from 1998 to 2002. Conclusions. ·Primary care is an appropriate level of care for ruling out IHD as the cause of chest pain, with sufficient safety and for diagnostics of stable IHD. ·Exercise testing and myocardial perfusion scintigraphy are useful procedures when investigating chest pain patients in primary care. ·The results indicate that preventive measures other than increased statin treatment should be considered to further decrease AMI-morbidity.

In the first trial, two hundred and forty 30-week-old hens were fed basal diet (commercial ration - CON1) supplemented with 0.1 % Probucol (PROB), 0.025% Gemfibrozil (GEMF), or Lovastatin at 0.0005% (LOV1), 0.001 % (LOV2) and 0.015% (LOV3) for a 12-week experimental period. In experiment 2, one hundred and twenty-eight 26-week-old hens were fed basal diet without animal products (CON2) containing either 0.2% Cholestyramine (CaL 1), 0.3% Cholestyramine (COL2) or 0.005% Lovastatin (LOV4) for a period of six weeks.

When correlation coefficients and regression equations were calculated, it was found that yolk weight increased linearly (p<0.05) as egg weight raised, and the higher the yolk weight, the higher the yolk cholesterol content, indicating that yolk cholesterol content changes may be partially explained by differences among egg weights.

Medical treatments with statins are prescribed to patients with increased risk of cardiovascular events. The benefits from statin treatment are well documented in clinical trials, but long-term adherence in patients is low, indicating that patients have an uncertainty about the necessity and benefits of treatment. The aims of this thesis were to investigate how patients and doctors view different aspects of statin treatment. Further aims were to investigate if the cardiovascular risk level in patients affects their views about different aspects of statin treatment. Yet further aims were to compare health behaviours and views about risk factors in patients using statins to a non-treated population. Data was obtained from patients (n = 829), doctors (n = 330) and a population sample (n = 720) using postal questionnaires. Views about the effect of statin treatment were assessed in different ways for patients and doctors. Patients based their assessments on their own situation, and doctors’ treatment decisions and assessments of anticipated effect of treatment were based on two hypothetical patient cases. The results indicate that patients greatly overestimate the general effect of statins, compared to efficacy results reported from clinical trials. Patients’ previous coronary heart disease or high overall risk were factors not associated with their views and expectations of treatment effect. Statin users with an internally perceived health control and patients satisfied with their doctor’s treatment explanation reported higher beliefs in treatment necessity and benefits. Statin users reported having better health behaviours and generally rated risk factors as more important than the non-treated population. Doctors had suboptimal understanding of the number of patients expected to benefit following five years of statin treatment and had a varying understanding of statins’ ability to prolong life. Overall the results illustrate that patients and doctors have different perspectives and views of the benefits from statin treatment which puts emphasis on how statin treatment is discussed in the clinical setting.
