ABSTRACT

The receptor for advanced glycation end products [RAGE] has been implicated in the pathogenesis of RA through its ability to amplify inflammatory pathways. [1] To evaluate the levels of soluble receptors of advanced glycated end products [sRAGE] as well as the gene variant among patients with rheumatoid arthritis [RA]. [2] To assess the association between the sRAGE level and the RAGE gene variants and to correlate the findings with various clinical and laboratory data. All patients were fulfilling the criteria for RA described by the American College of Rheumatology. In all patients assessment of disease activity was done by DAS28-ESR. Soluble RAGE level was determined by enzymatic immunoassay. Molecular study of single nucleotide polymorphisms [SNP] in the glycine82serine [G82S] of the RAGE gene was performed. The data was collected and statistically analyzed. Serum levels of sRAGE were significantly lower in RA patients than controls [840.11 +/- 230.32 pg/ml versus 1111.59 +/- 143.20 pg/ml, p < 0.05]. Genotyping of the RAGE gene showed polymorphisms in the glycine82serine [G82S] allele which did not reach statistical significance between patients and controls. The sRAGE levels were significantly lower in RA patients with Sjogren's syndrome and in those with cardiac disease. Correlation analysis showed that the glycine82serine [G82S] allele is related to MS, CRP and sRAGE in RA patients. Also, the G82S allele was more common in patients with cardiac affection. Linear regression analysis detected CRP and gene polymorphism as significant predictors for sRAGE level. The levels of sRAGE were significantly lower in patients with RA and this reduction was correlated with the disease activity parameters and glycine82serine gene polymorphism. The sRAGE may be an important marker of disease activity. The correlation of sRAGE level and cardiac disease can suggest that RAGE activity influences the co-development of joint and vascular disease in rheumatoid arthritis patients

ABSTRACT

A hiperglicemia näo-cetótica é uma doença genética, de herança autossômica recessiva, que causa distúrbios graves em recém-nascidos, podem levar à morte. Níveis aumentados de glicina no cérebro produzem lesäo neurológica irreversível. O diagnóstico clínico é confirmado por cromatografia líquida (HPLC), comparando-se os níveis de glicina em plasma e líquido cefalorraquidiano - uma relaçäo LCR/plasma maior do que 0,09 fecha o diagnóstico. O presente estudo relata dois casos de hiperglicemia neonatal com quadro clínico e evoluçäo neurológica semelhantes. Nos dois casos, os sintomas começaram nas primeiras 48 horas de vida, e näo havia antecedentes familiares, pré-natais ou perinatais. Os dois recém-nascidos apresentaram boas condiçöes ao nascimento. Além disso, em ambos os casos, o daignóstico laboratorial (HPLC) foi bastante tardio: as amostras de sangue total e liquor foram colhidas 55§ e no 17§ dia, respectivamente. As concentraçöes de glicina em LCR e plasma, e a relaçäo LCR/plasma, foram (em mg/dl), para as crianças número 1 e número 2, repectivamente: 2,8 e 3,3 (R=0,85); 2,4 e 8 (r=0,3). Muito embora os recém-nascidos tenham permanecido em unidade de terapia intensiva e suporte ventilatório e tenham sido medicados com benzoato de sódio e diazepam, o diagnóstico tardio da hiperglicinemia acarretou lesöes neurológicas graves e irreversíveis nas duas crianças. No entanto, a importância do diagnóstico laboratorial para o aconselhamento genético dos dois casais é inquestionável

ABSTRACT

Trinta e dois cäes submetidos a entubaçäo do ducto torácico e cateterismo bilateral dos ureteres, foram divididos em 3 grupos: A- 4 cäes inoculados com RISA 131 I ou EDTA 51 Cr por via intravenosa ou peri-prostática; B- controle de 8 cäes submetidos a irrigaçäo vesical e prostática com 8 litros de glicina a 1,2 por cento contendo os marcadores radioativos; C- 8 cäes manejados como em B mas sujeitos à RTU da próstata. Os cäes foram acompanhados por 5 horas. A absorçäo de líquido de irrigaçäo foi calculada pelos métodos volumétrico e radioisotópico. Em 5 horas, 97 por cento da RISA 131 I inoculada via intravenosa permanecia neste espaço enquanto apenas 4,6 por cento da injetada no espaço peri-prostático penetrou no compartimento vascular. Para o EDTA 51 Cr, 63,6 por cento da massa inoculada no espaço peri-prostático foi recuperada na urina após 5 horas. O método volumétrico mostrou absorçäo média de 22,7 ml no grupo B e 276 ml no C, e o radioisotópico de 6,3 ml e 165,4 ml, respectivamente. O modelo experimental tem similaridades com o ser humano

ABSTRACT

This study aimed at finding the possible immediate metabolic changes that may in the neonate of diabetic mother subjected to operative delivery under either general anesthesia or epidural analgesia. The study was carried out on 40 pregnant females undergoing elective caesarean section. Half of the cases were diabetic under control by oral hypoglycaemic drugs and the other half were non diabetic [control group]. In each of the studied group half of the patients undergoing caesarean section under general anesthesia, the other half under epidural analgesia. After labor a blood sample was taken from the umbilical cord of each neonate for the following: Serum blood glucose, serum insulin, corticosteroid and glycerol [as indirect index of catecholamines]. The same investigations were repeated after 4 hours. From this study, it can be concluded that foetus born after cesarean section to diabetic mothers have significantly high glucose and corticosteroids level than foetus born to non diabetic mothers. Insulin level did not show significant change. Epidural anesthesia was found to cause a significant low level of glycerol than general anesthesia due to reduction of stress response

ABSTRACT

A hiperglicinemia näo cetótica é erro inato do metabolismo que se manifesta por crises epilépticas de difícil controle desde os primeiros dias de vida, em recém-nascido hipotônico. A falta da enzima que catalisa a conversäo de glicina em ácido hidroximetiltetra-hidrofólico, dióxido de carbono e amônia, no fígado e no cérebro, resulta em aumento da concentraçäo de glicina no sangue. Neste estudo é relatado caso de hiperglicinemia diagnosticado no período neonatal e caracterizado por hipotonia e múltiplas convulsöes näo controláveis. Os achados clínicos e eletrencefalográficos, aspectos do tratamento e do estudo anátomo-patológico säo comentados
