Diffusion of thermophilic Campylobacter in the Pesaro-Urbino area (Italy) from 1985 to 1992.

The results of research on the spreading of campylobacter in the Pesaro-Urbino area carried out from 1985 to 1992 are presented. Materials of different origin were examined: 822 samples of human faeces, 533 animal rectal swabs, 192 samples of domestic sewage, 48 of river water, 96 of sea water and 632 of various types of food. Two hundred and nine strains of campylobacter were isolated (9%), most of which were Campylobacter jejuni (80%), with particular frequency in food products (chicken carcass 45.7%, ground meat and sausage 18.1%) and in river water (31.3%). In contrast, the samples of sea water and dairy cheese products were always negative. It may be concluded that the spreading of campylobacter in the Pesaro-Urbino area is mainly associated with food products of animal origin. Therefore, better controls in the processing of these products may be necessary.

Prevalence of anti-HCV in subjects of various age groups.

812 serum samples from 382 males and 430 females from various age groups were examined. All the samples were tested for anti-HCV hepatitis C virus, anti-HBc and HBsAg with an enzymeimmunoassay. The total serum prevalence was 2.9% for anti-HVC, 22.2% for anti-HBc and 4.6% for HBsAg. The seropositivity rates of anti-HCV and anti-HBc tended to increase with age, while for HBsAg a more regular pattern was observed for the different subject groups. The fact that anti-HCV are more frequently found together with HBV markers confirms the existence of similar modes of transmission of the two viruses.

Captopril and glutathione before thrombolysis in acute myocardial infarction: a pilot study.

This study is aimed at checking whether treatment with glutathione (GL) and captopril (CA) before thrombolysis can further improve the protective effects of ACE-inhibitors in cases with anterior acute myocardial infarction (AMI). Ninety-eight double blind randomized patients (86 men and 12 women) showing symptoms of AMI anterior and undergoing thrombolytic treatment were admitted to our study and subdivided into 4 groups. Group A (25 pts) received thrombolytic treatment only, Group B (23 pts) received 3 g GL intravenously 15 min before thrombolysis and for 2 h thereafter, Group C (26 pts) received 6.25 mg CA orally 15 min before starting thrombolytic treatment, Group D (24 pts) received 3 g GL intravenously before thrombolysis and for 2 h thereafter, and captopril as well like group C. On the third day after AMI onset groups A and B received CA also. In all groups, the doses of CA were gradually increased according to blood pressure values. The following features were considered: a) the occurrence of early (within the first 2 h after thrombolysis) ventricular hyperkinetic arrhythmias; b) CK peak; c) the normalization time of CK peak (NT); d) the occurrence of late ventricular hyperkinetic arrhythmias (VHA) in the predischarge Holter test (Lown's class 2); e) ejection fraction (EF) being measured in 60 pts undergoing haemodynamic test. The results were an follows: Group A: VHA early 13/25, CK peak 1982 +/- 282; NT 71 +/- 2 h; Late VHA 8/25; EF 53.5 +/- 2.5% (16 pts). Group B: VHA early 11/23; CK peak 1917 +/- 242 U/l; NT 69 +/- 3 h; late VHA 7/23; EF 54.5 +/- 5.4% (14 pts). Group C: VHA early 4/26; CK peak 1671 +/- 266 U/l; NT 58 +/- 3 h; late VHA 5/26; EF 55.5 +/- 3% (16 pts). Group D: VHA early 3/24; CK peak 1463 +/- 201; NT 56 +/- 4 h; late VHA 5/24; EF 57.6 +/- 4% (14 pts).

[Effect of captopril on human myocardial ACE-inhibition: neurohumoral variations during coronary sinus cardioplegia. Cardioprotective effect during aortocoronary bypass].

UNLABELLED: The present study is aimed at checking effects exerted by captopril on human myocardial ACE system (ACE-T) as well as the role played by tissue ACE-inhibition in reducing reperfusion damage. A human experimental model was used during cardioplegia due to aortocoronary bypass graft (CABG): 54 patients with coronary artery disease affecting 3 vessels having suffered from acute anterior myocardial infarction, homogeneous as far as ejection fraction (35-55%), number of grafts (3), clamping time, age and sex, were randomised in a double blind experiment, and were given captopril or placebo: 4 mg/l captopril were mixed into the cardioplegic solution with blood according to Buckberg, 8 blood samples were obtained from each patient and norepinephrine, epinephrine were assayed using an HPLC technique. Angiotensin 1 was assayed by RIA. CK was assayed as well (U/L). Blood samples were taken during CABG: pre-pump sample; pump sample; pump preclamping sample; coronary sinus sample; warm reperfusion sample; coronary sinus during warm reperfusion; after clamping sample; after cannulation. RESULTS: captopril group (29 patients): angiotensin 1:8.15; 6.9; 7.45; 8.66; 8.93; 8.70; 9.07; 9.40 versus placebo: 7.09; 7.43; 7.80; 9.31; 9.01; 8.35; 8.85; 8.07 mcg (all NS). Noradrenaline: captopril group: 359; 404; 329; 282; 263; 216; 310; 337 versus placebo: 439; 520; 499; 469; 526; 566; 501; 443 pg (p < 0.001). CK, captopril group: 79.9; 95.1; 100.8; 94.3; 104.2; 94.7; 108.4; 108 versus placebo: 76.2; 120.2; 135.5; 203; 225; 272; 247; 228.7 U/L (p < 0.01). Epinephrine values showed no significant difference between the 2 groups. Norepinephrine and CK decrease as well as angiotensin I increase in treated patients as compared to controls suggest some effect exerted by captopril ACE-T and its capability of reducing reperfusion damage and recommend its use for heart protection during CABG.

Our experience with combined hemodialysis-hemoperfusion treatment in chronic uremia.

Hemodialysis can remove only substances that are highly diffusable, non protein bound and with small and middle-molecular weights. The combination of Hemodialysis-Hemoperfusion (HD-HF) takes advantage of both techniques. Uremic patient could reduce the number of weekly dialysis sessions. Fourteen uremic patients were submitted twice a week to a combined HD-HP treatment for 16 months. Polymethacrylate coated charcoal was inserted in the dialysis circuit before the dialyzer. The treatment resulted in improvement of: MNCV (30.5 + -6 to 38.7 + -5.6 m/sec.) subjective symptoms (disappearance of pruritus and insomnia) and hematological status (red blood cells 3.1 x 106 to 4.02 x 106; and hematocrits 28.3 to 36.1). Good control of serum biochemistries. Creatinine and urea clearances of 228 and 236 ml/min respectively. Significant removal of middle-molecules uremic toxins determinated by gel-filtration on Sephadex G15. In conclusion, we state that combined HD-HP improves the detoxication possibilities in chronic uremia.

[Polycardiography in the diagnosis of latent cardiac insufficiency].

A group of heart patients and another group of healthy subjects have been studied and their systolic intervals (PEP-LVET - PEP/LVET ratio and the telediastolic index) evaluated using the mechanocardiographic system. In both long-standing and recent heart patients, the parameters studied showed significant deviations from the norm. These were even more marked after exercise on the ergonometer bicycle. Acute doses of digitalis reduced deviations from the norm observed under basal conditions and after exercise. Polycardiography, it is concluded, assists in the gathering of extremely valuable information about cardiac performance in relation to latent cardiac insufficiency. Especially useful information can be deduced from PEP indications and from the PEP/LVET ratio. The use of digitalis is suggested for physically active post-infarction subjects in order to give greater tolerance of physical exercise. The concept of long-term polygraphic studies as part of out-patient follow-ups on such patients is outlined.

[The vectorcardiogram of patients with artificial pacemakers].

Frank's technique has been used to study the behaviour of the vectorial loop in 20 subjects wearing fixed frequency pacemakers. A broad study has been carried out non characteristics and modalities of transmission of the artificial stimulus. The morphological features of the vectorcardiogram differ in accordance with the location of the stimulated point. Special attention is paid to the possibility of the catheter-electrode penetrating the coronary sinus during right intracavitary pacing and the consequent vectorial and radiological characteristics such an eventuality involves. Some remarks are offered on the orientation of the extrastimulus, depending on its point of origin. It is concluded that knowledge of the course of the vectorial curve may be extremely useful for establishing the site of the extrastimulus in pacemaker wearers.

[Behavior of the plasma level of digoxin in the rat in induced experimental hyperreninemia].

PRA, plasma and urine aldosterone levels and plasma digoxin were measured in rats in which digoxin had been administered under conditions of high PRA and high aldosterone levels experimentally induced by administering distilled water load and in rats in which digoxin had been administered without distilled water load. Results show that under conditions of high PRA and high aldosterone levels, plasma digoxin concentrations as measured 6 h after treatment were higher (45,3%) than in rats having received digoxin without water load. In assays carried out on rats sacrificed 12 h after digoxin treatment (with or without water load) all values approach basic levels again, thus suggesting that in rats too aldosterone might compete with digoxin at the level of tubular excretion.
