Anticorpos naturais e infecção: anticorpos naturais na doença de Chagas e na paracoccidioidomicose

Using ELISA technique, natural antibodies against self and non self antigens were determined in 80 patients chronically intected by T. cruzi and 40 individuals suffering from a deep mycosis frequentely found in Latin Amarica (Paracoccidioidomycosis - PCM). Two forms of PCM were investigated: adult forms and juvenil type of disease. Eighty percent (80%) of the former group had significantly elevated anti-laminin antibody levels (M=4.7,SD±1.8) compared with healthy controls and different specificities of antibody were associated with anti-laminin in pathological sera. A notable binding to cytoskeletal proteins was observed, specially with band 3 and their peptides derivates, such as 62 kDa peptide. By means of Protein A chromatography we were able to show that natural anti-Gal antibodies may be bound by their Fab region to other immunoglobulins and/or to Protein A by alternative sites of binding. The finding of lgG anti-Gal antibodies in circulating immune complexes isolated from chagasic sera supported the first alternative. However, it is possible that some of lgG anti-Gal antibodies, belong to VH111 subgroup of immunoglobulins, that bind directly to Protein A. Among the 40 sera from PCM examined, the majority was considered as not exhibiting a signilicantly higher binding than normal sera to antigens tested. However thirty percent (30%) of the chronic patients had an increased levels of natural antibodies at least for one specificity such as actyn, myosin and Gala1,3Gal epitopes. ln juvenil type of PCM the mean value found for actyn was also increased 2,42 (range 1,0 to 5,3). Utilizing the polyethylene glicol precipitation the presence of circulating immune complexes was investigated in PCM sera. Specific antibodies for soluble antigens from P. brasiliensis and natural antibodies against myoglobin, myosin and Gala1,3 Gal epitopes were characterized

Influência do tratamento fisioterapêutico em grupo no equilíbrio, na mobilidade funcional e na qualidade de vida de pacientes com Parkinson

Introduction: Parkinson’s disease (PD) is a chronic disease of the nervous system, characterized by degeneration of neurons in the mesencephalic substantia nigra, leading to a clinical state of rest tremor, bradykinesia, muscular rigidity and postural instability. Physical therapy seeks to act by slowing the progression of the disease and when done in a group and maintain and / or improving the motor skills of the individual, can provide psychosocial benefi ts. Objective: examine the infl uence of the physical therapy group in balance, functional mobility and quality of life of individuals with PD. Method: participated in this study 04 subjects were female, mean age 67.75 (± 9.5) years, with medical diagnosis of PD, stages 1 to 3 of the Hoehn & Yahr. Before starting treatment, subjects underwent an assessment of the balance (BBS), functional mobility (TUG) and the quality of life (PDQ-39).The treatment was performed in groups, for a period of 10 weeks, lasting 60 minutes each session twice a week, totaling 20 sessions of physiotherapy. Upon completion of the treatment period the subjects were again assessed for balance, functional mobility and quality of life. The data were analyzed using the Student t-test, with signifi cance level of 5% (p ≤ 0.05). Results: statistical analysis showed signifi cant differences in three variables: equilibrium (p = 0.010), functional mobility (p = 0.029) and quality of life (p = 0.004), after physiotherapy intervention. Conclusion: physiotherapy treatment was group provides better balance, functional mobility and quality of life of patients with PD.

Efeitos da Fisioterapia Respiratória na Mecânica Respiratória de Pacientes com Acidente Vascular Encefálico Ventilados Mecanicamente

Patients who went through a Stroke may require mechanical ventilation (MV) in the acute phase of the disease and, on MV, they may show alterations in the respiratory mechanic. Physiotherapy techniques are applied in patients on MV to improve their respiratory mechanic. Thus, the purpose of this study was to evaluate the effects of the Respiratory Physiotherapy into the dynamic compliance (Cdyn), static compliance (Cst) and airway resistance (Rwa) in Stroke patients on MV. In order to do that, patients with Stroke diagnostic on MV were evaluated, before and after the use of Physiotherapy techniques (manual rib-cage compression, thoracic decompression, zero end expiratory pressure and suctioning). Cdyn, Cst and Rwa were the researched variables. Statistical Analysis was made using Paired T-Test with statistical significance with p-values no greater than 5%. Eleven patients were part of the study, with an average of 64,6±12,5 years old. Cdyn increased after physiotherapy from 29,3±16,1 ml/cmH2O to 33,8±16,7 ml/cmH2O (p=0,03). Cst also increased from 44,4±20,7 ml/cmH2O to 54,0±26,6 ml/cmH2O (p=0,024). No significant difference was detected for Rwa between the before and after moments (Before – 8,0±3,2 cmH2O/l/s, After – 7,3±2,25 cmH2O/l/s; p=0,45). It was possible to conclude that both dynamic and static compliance increased after physiotherapy, but the airway resistance did not increase in patients with stroke on mechanical ventilation.

Distúrbios do Sono em Pacientes com Fibromialgia

Introdução: A fibromialgia é uma doença caracterizada principalmente por dor músculo-esquelética difusa e crônica. Os distúrbios do sono em fibromiálgicos podem ter papel não somente na etiologia da dor crônica, mas também na perpetuação dos sintomas, portanto o estudo das condições do sono nestes pacientes é relevante na medida em que possibilita um entendimento das condições fisiopatológicas e permite uma abordagem ampla para o tratamento da fibromialgia. Objetivo: Apresentar a relação entre os distúrbios do sono e os sintomas da fibromialgia e sua importância na avaliação dos fibromiálgicos. Metodologia: Foi realizado levantamento bibliográfico do período de 1990-2009, nas bases de dados Medline, Pubmed, Lilacs e Scielo, através das palavras chaves: sleep, fibromyalgia, sleep disorders, insomnia, pain. Resultados: A literatura demonstra uma alta prevalência de distúrbios do sono em pacientes portadores de fibromialgia e uma relevante relação entre as anormalidades no padrão do sono e o sintoma da dor crônica.

Fatores prognósticos e análise de sobrevida de pacientes diagnosticados com carcinoma espinocelular nos 10 primeiros anos do Centro de Oncologia Bucal da Unesp, Campus de Araçatuba

Objetivo: Estimar as probabilidades acumuladas de sobrevida dos pacientes diagnosticados com carcinoma espinocelular nos 10 primeiros anos do Centro de Oncologia Bucal da UNESP, Campus de Araçatuba, de 1991 a 2000, observadas até 2005, estabelecendo os possíveis fatores prognósticos significativos para o óbito. Méttodo: A análise de sobrevida foi realizada em uma coorte de 280 pacientes com carcinoma espinocelular, no Centro de Oncologia Bucal da Faculdade de Odontologia de Araçatuba, UNESP, entre 1991 e 2000. Para avaliar a associação entre as variáveis independentes e o óbito, realizou-se o teste Log Rank. A probabilidade do teste com p-valor menor que 0,25 ficou estabelecida para a inclusão das covariáveis no processo de ajustamento do modelo. A sobrevida foi estimada pelo método de produto limite de Kaplan-Meier. Os fatores prognósticos foram estimados pelo modelo de riscos proporcionais de Cox, calculando-se razão da função de risco (HR). A análise de resíduo foi realizada para verificar o ajuste do modelo. Resultados: As taxas de probabilidades acumuladas de sobrevida de 280 pacientes, para os casos em estádio IV, foram, 56,74%, 32,13%, 23,71% e 20,57%, respectivamente, até 1, 2, 3 e 5 anos após o diagnóstico. Pacientes no estádio I apresentaram sobrevida em 5 anos de 81,73%. O estadiamento clínico da doença no diagnóstico foi o único fator prognóstico definido no processo de ajuste de modelo. A estimativa da razão da função de riscos de morrer em pacientes diagnosticados no estádio III (HR=3,3), é praticamente três vezes o risco daqueles em estádio I; da mesma forma, o risco de morrer dos diagnosticados em estádio IV (HR=6,17) é cerca de seis vezes ao daqueles em estádio I. Conclusões: A covariável que permaneceu no modelo final foi estadiamento clínico no momento do diagnóstico, sendo, pois, o único fator prognóstico.

Detecção de DNA de micobactérias dos complexos M. tuberculosis e M. avium em amostras parafinadas de pacientes transplantados renais

Introduction: Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis. The genus Mycobacteriumhas two different complexes: M. tuberculosis Complex and M. avium Complex. This is a global health epidemic and remains a major global health problem, besides, the clinical severity of TB is significantly higher in transplanted patients. The detection of these mycobacteria complexes in transplanted patients, by molecular methods, is fundamental for quick treatment of patients and can contribute for rapid and accuracy of diagnosis. Objective: To detect mycobacteria DNA of M. tuberculosis and M. avium Complexes in formalin fixed paraffin-embedded samples (FFPE) of two patients groups: non transplanted and transplanted. Materials and Methods: The study includes 40 FFPE biopsies separated in four groups: NTP – presence of epithelioid granuloma and positive ZN, non-transplanted patients – 9 samples; NTN - presence of epithelioid granuloma and negative ZN, non-transplanted patients – 10 samples; TP – positive ZN, transplanted patients – 9 samples; TN – negative ZN, transplanted patients – 7 samples. Sections were cut for DNA extraction. Samples were submitted to PCR for amplification of: a) β-actin, b) IS6110 insertion and c) IS1245 insertion. DNA evaluation was made by spectrophotometry and efficiency and PCR analysis was made by agarose gels under UV light. Results: In all samples processed, 97.1% were positive for human β-actin gene. In22.2% of NTP group were found the IS6110 insertion sequencebut the IS1245 wasn´t. In the NTN group was not found any sequence. In theTP group, 11.1% of the samples were positive for IS6110 and also 11,1% werepositive for IS1245. In the TN group, 14.3% of the samples were positive forIS6110 and for IS1245, 14.3% was also positive. Conclusion: Although factors such as DNA degradation after formalin fixation and paraffin embedding, were possible to detect DNA from the human gene ...

Prevalência da excreção e caracterização molecular do poliomavírus humano JC em amostras de urina de pacientes com aids sem leucoencefalopatia multifocal pro-gressiva

The human poliomavirus is the etiologic agente of Progressive multifocal leukoencephalopathy (PML), a disease characterized by focal lesions not expansives of the central nervous system that develops in imunocompromissed patients, specially people with aids. The main aim of the study was to evalute the prevalence of the JCV excretion in urine samples of patients with aids, without PML, to compare two JCV DNA detection techniques through of two diferents genomic regions and to evaluate the genotypic characterization of the positive samples. A total of 75 samples were colected in the Instituto de Infectologia Emílio Ribas, in Sao Paulo, Brazil, between may and november, 2009. To detect the JC virus it was made the DNA extraction and then the polimerase chain reaction (PCR). Firstly a fragment of 215 bp was amplified, which corresponds to the codifying gene of the strutural protein of de JC vírus capsid VP1. All the samples were later submitted to another PCR that uses a pair of primers complementaries to the early region of the JCV (T antigen) amplifying a fragment of 173 bp. Followed by the digestion of the amplified product with the restriction enzime BamH1, resulting in two smaller fragments (120 bp and 53 bp). The JC vírus was detected in 53 samples, for both techniques (70,7% for VP1 PCR, and the restriction enzime BamH1), 34/46 were men (73,9%) and 19/29 were women (65,5%). The JCV excretion was higher in individuals that were over 46 years old. Regarding the seven genotypes described in the literature, the ones that were more prevalent among the JC positive patients were 3B and 3A with 10 samples each (21,0%), the 2B with 9 samples (19,0%) and genotype 6, with six samples (13,0%). As in the brown patients as the white ones, the most prevalent genotype was 3B. In the present study it was observed a high prevalence of JCV DNA (70,7%) and the genotype 3 (43,0%)...

Aspectos Nutricionais na Doença Renal Crônica em Cães

It is understood by Chronic Renal Failure (CRF) or Stage IV Chronic Kidney Disease (CKD) the morbid state in which there is a substantial and irreversible loss of functional capacity, metabolic and endocrine function in both kidneys, leading to a framework of dehydration, azotemia, electrolyte imbalance, anemia, uremic syndrome, secondary hyperparathyroidism, among other conditions that make the patient's life without treatment unfeasible. An adequate nutritional support to patients with CKD at any stage aims to maintain a good clinical condition and an attempt to delay the progression of the disease. The basis of a diet for patients with CKD is the restriction in this protein being of high biological value, low-phosphorus, high energy density, fiber and antioxidants combined with a good dietary practices that allow the patient a good quality of life
