[Course of ischemic risk in treated atheromatous hypertensive patients. The PRIHAM study (Prognosis of Ischemic Risk in Atheromatous Patients under Mediatensyl)].

Hypertension is one of the major cardiovascular risk factors. However it seldom occurs alone in a patient and the antihypertensive treatment should be taken into account when assessing global cardiovascular status. The PRIHAM study was an open study which enrolled 3,216 hypertensive atheromatous patients who already has had a clinical ischaemic accident. Patients were followed-up for 3 years. The lowering effect on cardiovascular risk, starting from the fifteenth month was confirmed to the end of 36-month study. The effect on blood pressure was observed from the third month. Stabilized blood pressure observed within the first year persisted throughout the three years without tachyphylaxis. It was effective on SBP (-14.4%) and on DBP (-15%) while maintaining a stable heart rate both in the supine position or immediately upon standing or after 3 minutes in the standing position. Tolerance was globally judged as good or very good by the investigating practitioners and the patients expressed an improvement in their feeling of well-being. In conclusion, from the level of effectiveness obtained and the low incidence of adverse effects, urapidil appears well adapted and easy to manage in a population with a particularly high cardiovascular risk.

[Is the indomethacin test able to indicate the etiological diagnosis of isolated fever?].

The aim of this study was to determine if evolution of fever after administration of indomethacin to febrile patients could separate those with fever of infectious origin from those with non-infectious origin. All patients with a rectal body temperature superior than 38 degrees C for at last 5 days and without any antibiotic or antipyretic therapy for more than 48 hours, were included in a 1 year prospective study. Each patient received one time 50 mg of indomethacin and rectal body temperature was obtained every 3 hours for 12 hours. Forty-five patients were included, 20 in group I (fever of infectious origin) and 25 in group II (fever of non-infectious origin). The mean age and mean initial body temperature were similar in the two groups. After administration of indomethacin, mean duration and mean amplitude of abatement of fever were similar in the two groups. Hypothermia was observed more frequently in group II (28%) than in group I (10%) (p < 0,05) and was preferentially associated to a malignant lymphoma. Also, diagnostic procedure with indomethacin is of little interest to separate fever of infectious origin from other, but hypothermia would suggest a fever due to a malignant lymphoma.

Amongst diabetic and dyslipidemic patients, an absence of deleterious metabolic effects was noticed, parallel with the effectiveness. Tolerance was globally judged as good or very good by the investigating practitioners and the patients expressed an improvement in their feeling of well-being. In conclusion, from the level of effectiveness obtained and the low incidence of adverse effects, urapidil appears well adapted and easy to manage in a population with a particularly high cardiovascular risk.

["Primum non nocere". Prospective study of 115 cases of iatrogenic diseases collected over one year in 106 patients].

One hundred and fifteen cases of iatrogenic disorders were observed in 106 patients during a one-year prospective study. Each case was included after informed agreement of two investigators. Each case was classified into 4 groups, according to duration time between iatrogenic disorder and hospitalization, and into 3 sections according to responsibility of causative agent. A control group of 200 patients matched for age and sex was studied. Patients represented 8% of the hospitalisations. Mean age (69.2 years) was higher than other patients hospitalized during the same period (61.6 years). Principal causative agents were diuretics (30), physchotrops (13) and technic examinations (12). Main pathologies were electrolytes disorders (28), orthostatic hypotension (19), confusion and/or alteration of mental functions (13), and cutaneous or allergic disorders (12). Mean induced hospitalization duration time was of 8 days. Mean estimate cost was 18,808 francs per patient. Associated factors were elderly, and an elevated number of drugs. A negligency could participate to iatrogenic disorders in 50% of cases. Half part of iatrogenic disorders could be avoided by using simple precautions: respect of contra-indications, restriction on self-therapy and of number of associated drugs.

[Is the immunologic evaluation in endocarditis of value?].

Forty-seven patients were included in a prospective trial to define the interest for searching immunologic abnormalities during endocarditis. No specific abnormalities were found, aside some patients with endocarditis who have a high levels of immune complexes. These results suggest that the interesting immunologic abnormality is the presence of an high level of immune complexes could be of interest in endocarditis.

Relationship of interleukin-4 to isotypic distribution of anti-double-stranded DNA antibodies in systemic lupus erythematosus.

IgG subclasses of anti-double-stranded DNA antibodies were determined in 182 patients with systemic lupus erythematosus. All isotypes were detected, but IgG1 and IgG3 were predominant (62 and 51% of the cases, respectively). An average of 64 +/- 27% was IgG1, 16 +/- 22% IgG2, 16 +/- 19% IgG3 and 4 +/- 10% IgG4. The rank order or frequency was IgG1, IgG3, IgG2 and IgG4 in patients with musculoskeletal involvement; IgG1, IgG2, IgG3 and IgG4 in those with renal complications; IgG3, IgG1, IgG2 and IgG4 in those with cutaneous involvement; and IgG1, IgG3, IgG2 and IgG4 in those with hematological manifestations. Interleukin-4 (IL-4) was detectable in 17 of 36 selected patients, as opposed to 1 of 40 normal controls. The percentage of the total autoantibody contributed by IgG1 was significantly higher (p < 0.03) in these patients than in the remainder with undetectable levels of IL-4.

[Rapidly progressive glomerulonephritis in macroscopic periarteritis nodosa. 7 cases].

Rapidly progressive glomerulonephritis (RPGN) is rarely associated with macroscopic polyarteritis nodosa (PAN), as seen in this series of 7 out of 235 patients. The clinical symptoms of PAN were as follows: myalgias 6; fever 1; arthralgias and mononeuropathy multiplex 5; cutaneous vasculitis 3; arterial hypertension 4, 3 of which were malignant. The mean proteinuria was 2.7 g/24 h; creatininemia 458 microM/l; microscopic hematuria was present in 4 of the 7 patients; only 1 patient was anuric. Markers of hepatitis B virus were absent in all cases. Arteriography revealed microaneurysms and renal infarcts in 6 patients and distal arterial stenosis in one. Renal biopsies from all 7 patients demonstrated extracapillary glomerulonephritis, which was associated with tubulointerstitial fibrosis in one. Necrotizing vasculitis lesions were associated in 5 cases. Immunofluorescence was positive in 5 cases. The association of RPGN and PAN exists and may be underestimated due to the lack of systematic angiographic examinations during RPGN and renal biopsies in PAN patients with renal involvement.

[Idiopathic retroperitoneal fibrosis and ankylosing spondylitis].

A case of ankylosing spondylarthritis in which retroperitoneal fibrosis developed 16 years after onset is reported. The patient also had aortic incompetence and cardiac conduction disorders. Eight other cases of ankylosing spondylitis with retroperitoneal fibrosis have been published. Potential relationships between the two conditions--including the possible role of indomethacin used by the patient for 16 years--are discussed.

Polyarteritis nodosa related to hepatitis B virus. A retrospective study of 66 patients.

In an attempt to establish the characteristics, circumstances leading to infection and development of polyarteritis nodosa (PN) related to hepatitis B virus (HBV), prognostic factors and outcome, and to define the most effective treatment, 66 patients observed between 1972 and 1989 were analyzed. Hepatitis was clinically present in 19/66 patients before PN. In most cases, PN occurred less than 6 months after infection. Clinical manifestations of PN were comparable to those observed in patients without HBV infection except for orchitis which was present in 13.6% and for pulmonary signs which were absent. Transaminases were normal in 38 cases for SGOT and 31 for SGPT and twice the normal range or more in the other cases. Antineutrophil cytoplasmic antibodies (ANCA) were tested in 22 patients and present in 2 (9%). Twenty-eight patients were treated with prednisone +/- oral cyclophosphamide +/- plasma exchanges. Thirty-eight patients were given a short-term treatment with prednisone followed by the association of vidarabine, 15 mg/kg bw/d for one week and 7.5 mg/kg bw/d for 2 weeks, and plasma exchanges: 14 sessions during the 3 weeks of vidarabine infusion, then tapered until stopping treatment after 2 to 3 months depending upon the clinical results obtained. The mean duration of follow-up was 50.3 +/- 46.1 months. At the end of follow-up, 13 of the 28 patients (46.4%) treated with steroids +/- cyclophosphamide +/- plasma exchanges died and 7/38 (18.4%) of those treated with vidarabine and plasma exchanges (p < 0.001) died. HBe/anti-HBe seroconversion was observed in 2 patients treated with prednisone +/- cyclophosphamide +/- plasma exchanges who were alive at the time of final analysis and in 16 patients receiving the other regimen. The outcome of patients treated with a few days of prednisone, vidarabine and plasma exchange was good and, therefore, we propose this protocol as the first viable treatment for polyarteritis nodosa related to HBV, surpassing the conventional treatment with steroids and cyclophosphamide, which stimulates viral replication.

[Antenatal diagnosis of holoprosencephaly and its consequences. Apropos of 2 cases].

Cyclops represents the worst form of a rare malformation of the brain and face: holoprosencephaly. Two cases are reported, including one that was diagnosed at the 23rd week of pregnancy. Now, ultrasonography makes it possible to diagnose early; as soon as the 15th week of gestation. Ultrasound diagnosis is based on hypotelorism and anomalies of the mid-line, with or without facial abnormalities. The outcome is always poor. This malformation is associated with various conditions and a complete assessment, including the karyotype, morphologic studies of the fetus and of his family, and search for related minor facial dysmorphias (median labial or cleft palate with, with a single upper incisor) is mandatory. The condition recurs in 2 to 50% of cases depending on various associated conditions and on the family histories.

Amoxycillin/clavulanic acid ('Augmentin') compared with a combination of aminopenicillin, aminoglycoside and metronidazole in the treatment of pelvic inflammatory disease.

A randomized, multi-centre trial was carried out in 152 hospitalized women with pelvic inflammatory disease to evaluate the efficacy and tolerability of amoxycillin/clavulanic acid compared with that of a standard regimen using three antimicrobial agents (aminopenicillin, an aminoglycoside and metronidazole). Seventy patients initially received 3 to 4 intravenous doses per day of 1 g amoxycillin/200 mg clavulanic acid (mean 7.7 days) and then 4 to 6 tablets per day of 500 mg amoxycillin/125 mg clavulanic acid (mean 11.2 days). The other group of 82 patients initially received parenteral therapy daily (mean 7.7 days) with a combination of 3 to 4 g amoxycillin or ampicillin, 160 mg gentamicin (or 150 mg dibekacin or tobramycin) and 1.5 g metronidazole, and then oral therapy with 2 to 3 g amoxycillin or ampicillin and 1 to 1.5 g metronidazole daily (11.1 days). Clinical results, assessed at discharge from hospital (mean 10 days in both groups), were comparable in both groups, with 96% complete or partial response and no failures in the amoxycillin/clavulanic acid group, and 90% complete or partial successes and 5 failures with the triple therapy regimen. Both treatments were well tolerated and very few side-effects were reported.

[Drug addiction and pregnancy. Principal obstetrical and pediatric complications].

The principal obstetrical and paediatric sequelae were studied in 22 heroin addicts who were followed up at Lariboisière Hospital in Paris between 1980 and 1984. The main effects were on the fetus with 45% showing growth retardation below the 10th percentile, 65% fetal distress, 9% prematurity; 33% had infections and 66% had the withdrawal syndrome. Because of this pathology a high number had to be transferred. Considering the period of study, HIV infection could not be evaluated. The most dramatic result seems to be the long-term effect on these children because only a third apparently live with their families and several suffer from abnormalities in psychomotor development.

HLA class II genes polymorphism in DR4 giant cell arteritis patients.

We have previously reported a significant increase of HLA-DR4 antigen frequency in giant cell arteritis (GCA). This finding suggested an important role of immunogenetic factors in this syndrome. Recent data suggest that inherited susceptibility to several autoimmune diseases was associated with specific DR4 associated DQ beta alleles. DNAs from 27 DR4 positive patients with GCA were digested with Taq I and Bam HI, analysed on 0.7% agarose gel and hybridized with DR beta, DQ alpha and DQ beta probes. DR beta hybridization produced no variant detectable within DR4. DQ beta probe confirmed two clusters among DR4 associated DQW3 alleles: DQW 3.1 (Bam HI 360 Kb) and DQw 3.2 (Taq I 1.9 Kb and Bam HI 11 Kb). Among our 27 DR4 positive patients, 34% were DQW 3.1 and 66% were DQW 3.2. These frequencies are the same as those observed in healthy controls.

[Prognosis and treatment of glomerulonephritis of periarteritis nodosa. The role of plasma exchange].

Fourteen patients with polyarteritis nodosa complicated by histologically confirmed glomerulopathies were included in a prospective multi-center study comparing corticotherapy (group 1, n = 8) with combined cyclophosphamide and steroids (group 2, n = 6). Plasma exchanges were associated on a routine basis. The two groups were comparable apart from initially more severe renal impairment in group 1 (p less than 0.05). Initial control of the disease was obtained in 11 patients (7 from group 1, 4 from group 2) including the patients with oligoanuria. Six patients recovered, 3 had recurrence requiring chronic hemodialysis and 5 patients died from group 1 (p less than 0.05). These preliminary findings suggest that plasma exchange can contribute to control of polyarteritis nodosa with renal complications.

[Prenatal diagnosis and treatment of auricular flutter. Apropos of a case and review of the literature].

In newborns, atrial flutter is a rare, but severe condition. Late diagnosis was usual and based on fetal ECG. Now, fetal ultrasonography can differentiate in utero atrial flutter and other supra ventricular tachycardias; so it can be treated before development of cardiac failure. Among numerous and various available drugs, digoxin is universally recommended, but the delayed effect and the maternal serum levels to obtain effective fetal concentration of digoxin are not well known. Furthermore, endogenous "digoxin-like" substances have been found in maternal blood in late pregnancy; this finding raises the problem of the validity of monitoring the treatment only by serum digoxin levels. A case of atrial flutter, diagnosed in utero by ultrasonography and treated by digoxin before development of cardiac failure is reported. Neonatal echocardiography showed an aneurysm of the atrial septum, which needed simple monitoring. Its responsibility in the pathogenesis of the arrhythmia is unclear. Numerous cases of aneurysm of the atrial septum have been reported in healthy adults without atrial arrhythmias.
