ABSTRACT

Objetivo: Avaliar a influência da terapia na morfologia da epiderme de pacientes com Síndrome da Imunodeficiência Adquirida - AIDS. Metodologia: Estudo transversal desenvolvido na Universidade Federal do Triângulo Mineiro, Brasil. Foram selecionados pacientes com AIDS de ambos os sexos, que foram agrupados de acordo com o tratamento com Terapia antir-retroviral de alta eficiência: pacientes em uso de HAART (n = 14) e pacientes sem uso de HAART (n = 14). Outras informações foram coletadas do prontuário clínico. Resultados: A idade média dos pacientes em tratamento foi de 49,07 ± 7,89 anos e dos pacientes sem TARV foi de 55,11 ± 10,17 anos. A maioria dos pacientes na terapia utilizada pertencia ao sexo feminino, 9 (64,28%). Estes apresentaram espessamento epidérmico (150,04 x 86,09µm), número de camadas celulares (8,0 x 5,5 camadas) e densidade de células de Langerhans superiores àquelas que não utilizaram a terapia, com diferença significativa. Conclusão: Nossos achados sugerem que o HAART propor-ciona a recuperação dos constituintes da epiderme alterados pela doença, melhorando sua função como barreira chave na proteção do corpo contra microorganismos ambientais.

Objective: To evaluate the influence of therapy in the morphology of the epidermis of patients with Acquired Immunodeficiency Syndrome. Methodology: Cross-sectional study developed at the Triangulo Mineiro Federal University, Brazil. This study has been approved by Triângulo Mineiro Federal University Research Ethics Committee on protocol number 1780/2010. Patients with AIDS, of both genders were selected and arranged according to treatment with Highly Active Antiretroviral Therapy: patients in use of HAART (n = 14), and patients without use of HAART (n = 14). Other information was collected from the clinical record. Results: The mean age of the patients undergoing therapy was 49.07±7.89 years, and of the patients without HAART was 55.11±10.17 years. The majority of the patients using the therapy, belonged to the female gender, 9 (64.28%). These showed epidermal thickness (150.04 x 86.09µm), number of cell layers (8.0 x 5.5 layers) and density of Langerhans cells higher than those who did not use the therapy, with a significant difference. Conclusion: Our findings suggest that the HAART provides recovery of epidermis constituents altered by the disease, improving its function as a key barrier in protecting the body against environmental microorganisms.

ABSTRACT

Abstract Objectives: to compare the percentage of collagen fibers in the autopsied women's uterine body and cervix with and without the Acquired Immunodeficiency Syndrome (Aids). Methods: 30 autopsied women's medical files were selected from 1988 to 2013. 30 fragments of the uterine body and 30 cervix were collected and then divided into two groups, 15 with Aids and 15 without, The quantification of the collagen fibers of the uterine body and cervix was performed on slides stained with picrosirius, using the KS-300® system. Results: the percentage of collagen fibers was lower for cervix (U=336544; p=0.001) and higher for the uterine body (U=308726,5; p=0.004) in the retroviral group when compared to the group without the disease. The percentage was higher for cervix than the uterine body in the group with Aids (t=0,4793; p=0.0031). the same result was found in the group without Aids (t=2,397; p=0.0637). Conclusions: the increase in the percentage of collagen fibers in the uterine body of women with Aids' indicates an immune response for viral infection and reveals a failure in keeping the infection restricted to the cervix. The interpretation of the histochemical and morphometric parameters can be useful in the diagnosis associated to HIV infection, contributing for clinical improvement and life expectancy.


Resumo Objetivos: comparar a porcentagem de fibras colágenas no corpo e colo uterino de mulheres autopsiadas com e sem a Síndrome da Imunodeficiência Adquirida (Aids). Métodos: foram selecionados 30 prontuários de mulheres autopsiadas no período de 1988 a 2013. Foram coletados 30 fragmentos do corpo uterino e 30 do colo uterino, dividido em dois grupos, 15 com Aids e 15 sem. A quantificação das fibras colágenas do corpo e colo uterino foi feita nas lâminas coradas por picrosirius, utilizando-se o sistema KS-300®. Resultados: a porcentagem de fibras colágenas foi menor no colo (U=336544; p=0,001) e maior no corpo uterino (U=308 726,5; p=0,004) no grupo com a retrovirose quando comparado ao grupo sem a doença. A porcentagem no grupo com Aids foi maior no colo uterino do que no corpo (t=0,4793; p=0,0031). Sendo o mesmo resultado encontrado para o grupo sem Aids (t=2.397; p=0,0637). Conclusões: um aumento da porcentagem de fibras colágenas no corpo uterino das mulheres com Aids indica uma resposta imune frente a infecção viral e revela uma falha em manter a infecção restrita ao colo. A interpretação dos parâmetros histoquímicos e morfométricos podem ser úteis no diagnóstico das condições associadas à infecção pelo HIV, contribuindo para a melhora clínica e expectativa de vida.

ABSTRACT

Summary Introduction: Alcoholism is a major public health problem, which has a high social cost and affects many aspects of human activity. Liver disease is one of the first consequences of alcohol abuse, and steatosis, liver cirrhosis and hepatitis may occur. Other organs are also affected with pathological changes, such as pancreatitis, cardiomyopathies, dyslipidemias and atherosclerosis. Objective: To identify the occurrence and degree of atherosclerosis in alcohol-dependent individuals with liver cirrhosis, observing macroscopic and microscopic changes in lipid and collagen deposits and in the liver. We also aimed to verify the association of lipid and collagen fiber deposits with gender, age and body mass index, and to relate alcoholism, liver cirrhosis and atherosclerosis. Method: We performed a study based on autopsy reports of patients with alcoholic liver cirrhosis, with analysis of aorta and liver fragments to verify the occurrence and degree of atherosclerosis, as well as collagen contents. Results: Microscopic atherosclerosis was higher in young subjects (early injury) and in patients with alcoholic liver cirrhosis. The macroscopic analysis of atherosclerosis in aortas showed that patients in more advanced age groups presented more severe classifications. Atherosclerosis, both micro and macroscopically, and the percentage of fibrosis in the liver and aorta were more expressive in females. Conclusion: Cirrhotic patients presented a higher percentage of fibrosis and lipidosis, and may represent a group susceptible to the accelerated progression of cardiovascular diseases. Investigative studies contribute to targeting health-promoting interventions, reducing the mortality and costs of treating cardiovascular disease.


Resumo Introdução: O alcoolismo é um grande problema de saúde pública, de elevado custo social e que afeta vários aspectos da atividade humana. Hepatopatia é uma das primeiras consequências do abuso de álcool, podendo ocorrer esteatose, cirrose hepática e hepatite. Outros órgãos, porém, também são afetados, ocorrendo alterações patológicas, como pancreatite, cardiomiopatias, dislipidemias e aterosclerose. Objetivo: Identificar a ocorrência e a intensidade de aterosclerose em alcoolistas com cirrose hepática, observando alterações macro e microscópicas do depósito lipídico e de fibras colágenas e fígado. Verificar a associação de depósito lipídico e de fibras colágenas com gênero, idade e índice de massa corporal (IMC). Relacionar alcoolismo, cirrose hepática e aterosclerose. Método: Foi realizado estudo com base em laudos de autópsias de pacientes com cirrose hepática alcoólica, sendo estudados aortas e fígados para verificar a ocorrência e a intensidade de aterosclerose, bem como a quantidade de colágeno encontrada. Resultados: A aterosclerose microscópica foi maior em jovens (lesão inicial) e em pacientes com cirrose hepática alcoólica. A análise macroscópica da aterosclerose nas aortas mostrou que pacientes com faixas etárias mais avançadas apresentaram classificações mais intensas. A aterosclerose, tanto micro quanto macroscopicamente, e a porcentagem de fibrose no fígado e na aorta foram mais expressivas no gênero feminino. Conclusão: Os pacientes cirróticos apresentaram maior porcentagem de fibrose e lipidose, e podem representar um grupo susceptível à acelerada progressão de doenças cardiovasculares. Estudos investigativos contribuem para o direcionamento das intervenções promotoras da saúde, reduzindo a mortalidade e os custos no tratamento das doenças cardiovasculares.

ABSTRACT

OBJECTIVES: To describe the morphological features of atherosclerosis in the aortas of autopsied patients (ranging from young adults to the elderly), thus providing new tools for a more sensitive morphological evaluation. METHOD: We collected 141 aorta samples. We assessed the macroscopic degree of atherosclerosis, thickness of the intima and media, lipid and collagen depositions in the intima, and the infiltration of mast cells into the layers of the aorta. We correlated the findings with gender, age, race and cause of death. RESULTS: The degree of atherosclerosis was significantly higher in the elderly. The aorta was thicker in the elderly and in cases with a cardiovascular cause of death. The thickness of the intima was significantly greater in the elderly, in males and in cases with a cardiovascular cause of death. The lipid content in the intima of the aorta was significantly higher in Caucasians. Older people and men had a significantly higher number of mast cells. CONCLUSION: A macroscopic evaluation is a good indicator of the severity of atherosclerosis, but a more detailed analysis, namely evaluating the thickness of the layers of the aorta and the number of mast cells, may further elucidate the changes in the constituents of this vessel.
