ABSTRACT

A inflamação é caracterizada por uma complexa série de eventos que surgem como resposta a uma agressão orgânica. O presente artigo descreve os mecanismos através do qual esse processo ocorre e as principais substâncias envolvidas. Dor, calor, rubor e edema são os sintomas cardinais, mas além dessas alterações locais, manifestações sistêmicas, como febre, podem estar presentes

ABSTRACT

Relata-se o caso de um individuo do sexo masculino, de 52 anos de idade, que desde 20 anos atras vinha apresentando sinais e sintomas de hanseniase multibacilar, mas so procurou tratamento apos 5 anos, quando apresentava manifestacoes de Eritema Nodoso Hansenico (ENH - Reacao tipo 1) inclusive com comprometimento articular. Instalado o tratamento (PQT/MB) o paciente passou a apresentar episodios de ENH, que se continuaram apos a alta medicamentosa alternando-se ou em concomitancia com episodios de reacao tipo 1 (reacao reversa) o que definiu como dimorfo. Assim permaneceu quase 10 anos, tendo apresentado, por algum tempo, esplenomegalia e sinais de hiperesplenismo. So melhorou, quando a deteccao de bacilos viaveis levou a reinstalacao da PQT. A discussao do caso ressalta alguns aspectos interessantes desta evolucao: 1) a demora no diagnostico leva pacientes dimorfos a adquirirem caracteristicas virchovianas com rica baciloscopia (virchovianos sub-polares); 2) estes pacientes tem maior possibilidade de albergarem bacilos persistentes que eventualmente se multiplicam e estimulam reacoes tipo I; 3) a alternancia de reacoes tipo 1 e tipo 2 pode indicar a participacao da imunidade celular no desencadeamento do ENH, onde a reacao granulomatosa romperia os infiltrados especificos regressivos, expondo antigenos intracelulares. Frente ao estado de hipersensibilidade humoral, haveria deposicao de complexos imunes e desencadeamento de reacao inflamatoria aguda; 4) a alta da PQT nao significa cura da hanseniase.

ABSTRACT

É apresentado o caso de um paciente virchoviano tratado com rifampicina e dapsona durante seis meses e depois somente com dapsona durante 14 anos. Depois de permanecer sem lesões e com baciloscopia negativa por 10 anos, voltou a apresentar lesões, desta vez do tipo dimorfo e com aparecimento de bacilos. Os autores sugerem que paciente sempre tenha sido um dimorfo e que havia piorado a ponto de apresentar aspectos virchovianos. Quando os bacilos voltaram a aparecer, a imunidade celular que o paciente sempre teve começou a destruí-los e daí o aparecimento de lesões dimorfas como deve ter sido no início de sua doença. Eles discutem também as causas possíveis que levaram os bacilos, possivlmente persistentes, a voltarem a se multiplicar.

ABSTRACT

Chronic allergic inflammatory reactions involve the infiltration and participation of many different cell types. Although it has been evident for many years that tissue specific mast cells have a primary role in the early stages of these reactions, recent studies indicated that, in addition to mast cells response, a later reaction which selectively recruits the circulating lymphocytes, eosinophils and basophils to the site of inflammation, is the hallmark for the progression of allergic diseases.

ABSTRACT

Circadian variation of temperature, both normal and febrile, is a well known fact. Mediators of fever are also regulators of acute phase response and are associated with stimulation of pituitary hormone production related with defervescence and with a circadian pattern of secretion. Acute phase response may consequently have circadian variations in its components. Measurements of temperature, erythrocyte sedimentation rate, complete blood cell count, serum cortisol and fibrinogen were made at 7:00, 15:00, and 23 h during two consecutive days in 35 patients with fever and acute infection, 15 patients with clinically active ankylosing spondylitis without fever and 10 healthy volunteers. Temperature curves showed statistically significant circadian rhytms, with higher values at night and lower ones during early morning. Erythrocyte sedimentation rate, leukocyte count and fibrinogen also showed statistically significant circadian rhytms, but with higher values at 15:00 h. Serum cortisol also showed statistically significant circadian rhythmicity but with a higher rhytms adjusted mean (MESOR), and a 100º (6 h) phase shift in patients with fever, as compared to patients with ankylosing spondylitis and healthy controls. In conclusion, components of acute phase response, including fever, have circadian rhythmicity, but asunchronically. Differences between fever and ankylosing spondylitis can be due to the intensity of acute phase response stimulation

ABSTRACT

Thirty-one patients bitten by venomous snakes in Botucatu area (State of Säo Paulo - Brazil), sixteen by Bothrops spp. and fifteen by Crotalus durissus terrificus, were studied. The group comprised twenty-nine males and two females, ranging from fourteen to sixty-three years of age (mean 33 ñ 15.Leukocytosis with neutrophilia and lymphopenia, increase of mucoproteins and C reactive protein, decrease of total serum protein and albumin, were observed on the first day after the accident. In addition, increased serum levels of the cytokines IL-6 and IL-8, but not of IL-1 beta and TNF-alpha, were observed. The alterations were generally more intense in patients bitten by Crotalus durissus terrificus than by Bothrops spp. It is concluded that these snakebite envenomations closely resemble an acute trauma, inducing a typical acute-phase response.
