RESUMO

OBJECTIVE: (1) To evaluate the corticosteroid sparing effect of an initial intravenous (i.v.) pulse of methylprednisolone (MP) in the treatment of simple forms of giant cell arteritis (GCA). (2) To analyze corticosteroid response, steroid related side effects, and GCA complications. METHODS: Patients received a 240 mg i.v. pulse of MP followed by 0.7 mg/kg/day oral prednisone (Group 1) or 0.7 mg/kg/day prednisone without an i.v. pulse (Group 2, controls), or a 240 mg i.v. pulse of MP followed by 0.5 mg/kg/day prednisone (Group 3). Corticosteroid dosage was reduced after normalization of 2 biological inflammatory variables to obtain half-dosage after 4 weeks in Groups 1 and 2 and 20 mg/day after 2 weeks in Group 3. Tapering was systematically attempted from the 6th month of treatment. RESULTS: One hundred sixty-four patients were included in the trial (1992-96). Cumulative doses of corticosteroids after one year were identical for all groups (p = 0.39). No significant differences were observed in the time required for normalization of C-reactive protein, corticosteroid resistance (13.5%), and corticosteroid related side effects (39% of patients; p = 0.37). Corticosteroid resistant patients received larger doses and showed a high risk of GCA related complications (p = 0.02). CONCLUSION: MP pulses have no significant longterm, corticosteroid sparing effects in the treatment of simple forms of GCA and should be limited to complicated forms. Moreover, corticosteroid resistance is a real risk factor for GCA complications.

RESUMO

Peri-aortitis retroperitoneal fibrosis is characterized by a reaction of a variable inflammatory nature while constricting the organs crossing the retroperitoneal space, notably the ureters and the blood vessels. It is difficult to diagnose such a rare disease. We bring about here six cases of periaortic retroperitoneal fibrosis diagnosed from systemic, digestive, urinary or vascular signs. Early diagnosis is often difficult and is shown to be established after an average of three months investigation. The average age of these patients, all of the male sex, is 58 years old (54 to 90). In the six cases this disease appears to be idiopathic even though in two cases it is associated to giant temporal arteritis and polymyalgia rheumatica. TDM remains the best diagnostic tool to point out the existence of this fibrosis, to observe its evolution and to investigate for any extension of the disease. The etiology of this fibrosis remains a mysterious one; however an immunologic origin has been suggested. Medical treatment by corticosteroids is often successful but the long term evolution of the disease is still uncertain.

RESUMO

Etiology of deep vein thrombosis in ambulant patients (DVTA = TVPA in text) varies: cancer, blood disease, infectious focus, dysimmunity syndrome, dysglobulinemia, extrinsic compression, metabolic disorder, anomaly of hemostasis. A prospective study was carried out between June 1988 and September 1989 by angiologists in 5 regions of France to evaluate the diagnostic rentability of an epidemiologic survey and to determine possible distinctive characters of DVTA. The survey was comprised of a questionnaire, a full clinical examination and screening tests: chest x-ray, abdominopelvic ultrasound imaging, a-uro/gynecologic examination, full blood count, serum iron, ferritin, uric acid, triglycerides, cholesterol, protein electrophoresis, antinuclear antibodies, circulating anticoagulant, hemostasis factors and liver function tests. The study included 128 patients, mean age 60 +/- 16 years with a DVTA developing without a previous immobilization. The usual predominance in the left leg was not observed. The etiology was identified in 33 cases, including 20 (15.6%) as a result of the screening tests: anomalies of hemostasis (8), blood diseases (3), dysimmunity syndromes (4), extrinsic compression (3), cancer metastasis (1) and hypertriglyceridemia in a diabetic (1). The screening procedure was of no greater value in the absence of a triggering or predisposing factor, on the contrary. An anomaly of hemostasis was detected more frequently in the presence of local or regional triggering factors in the men (4 out of 4) and in the women on the pill (4 out of 4). The number of cancers discovered following screening (2%) was smaller than that expected according to the literature (10%).(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

Single dose disposition of oral quinidine (400 mg sulfate) was studied in a control group of subjects (No. = 6) and in hospitalized alcoholic patients involving one group with (No. = 6) and one group without (No. = 11) hepatic cirrhosis. All subjects also underwent an antipyrine and a debrisoquine test. Patients with cirrhosis had a prolonged elimination half-life (29.5 +/- 5.9 h) and low clearance (24 +/- 7 ml.kg-1.h-1) of antipyrine and also a considerably higher debrisoquine metabolic ratio (18.8 +/- 3.3) than the controls, whereas the alcoholics without cirrhosis had metabolic patterns for these two test compounds comparable to those seen in the controls (antipyrine half-life: 8.8 +/- 1.1 h and 9.8 +/- 2.0 h; debrisoquine metabolic ratio: 3.6 +/- 0.7 and 3.8 +/- 1.2 for alcoholics and controls respectively). In patients with cirrhosis the apparent elimination half-life of quinidine was longer (12.8 +/- 1.8 h) whereas after oral administration clearance of quinidine (15.6 +/- 3.5 l.h-1) and quinidine/3-hydroxyquinidine ratio (9.9 +/- 2.1) were not different from controls (quinidine clearance: 13.45 +/- 1.9 l.h-1; quinidine/3-hydroxyquinidine: 10.3 +/- 2.7). A possible change in distribution patterns of quinidine in cirrhotics may explain these findings.

RESUMO

Stiffness of the jaw was noted in the first descriptions of temporal arteritis. It was only in 1944 that Horton used the term intermittent claudication and related this sign to effort ischemia due to thrombosis of facial arteries. The introduction of ultrasound techniques has enabled the permeability of facial arteries to be confirmed in spite of induration and absence of pulsatility clinically. Anatomical studies have defined the preponderant role of the internal maxillary artery in the vascular supply of the masseter muscles and have enabled the localization of an appropriate and reliable site for ultrasound study: the pterygo-maxillary fossa. The velocimetric data thus collected confirm that the internal maxillary artery is affected and define the etiopathogenesis of intermittent jaw claudication during temporal arteritis. This sign is observed on average in one patient in three suffering from temporal arteritis. While several cases of intermittent jaw claudication have been described in severe atheromatous stenosis of the common carotid or external carotid arteries, or in relation to other causes (rheumatological, neoplastic, psychological ...), the observation of this syndrome in a suspicious clinical and paraclinical context constitutes an excellent orientation sign in favor of temporal arteritis.
