Definitions
- the present invention relates to the use of nitric oxide for the manufacture of a medicament for inhalation intended for humans or animals.
- a drug to be inhaled can be used for the purposes of prevention and / or treatment of immune reactions of the inflammatory type caused by temporary extra-corporeal blood circulation, in particular during a cardiac surgery operation.
- Nitric oxide is produced naturally in humans or animals by an enzyme, NO-synthase, which is expressed constitutively in endothelial cells, platelets, and the central and peripheral nervous systems. Another form of calcium-independent NO-synthase can be induced by different stimuli, including liposaccharides, in many cells such as macrophages, lymphocytes, myocardial cells, endothelial and smooth muscle cells. Nitric oxide is also produced in large quantities in the respiratory tract, particularly in the paranasal sinuses. Each time you breathe in, the nitrogen monoxide produced is self-inhaled.
- Nitric oxide is therefore an important biological messenger in humans and animals.
- NO also plays a decisive role in the local control of hemodynamics. Indeed, the release of NO by endothelial cells has been demonstrated in the event of variations in blood flow. Nitrogen monoxide appears in particular as a major component of the physiological adaptation of the vascular diameter to blood perfusion; thus, at the coronary level, reactive hyperaemia is markedly attenuated in the absence of NO. Conversely, a chronic increase in blood flow produced by an arteriovenous fistula increases dependent relaxations of the endothelium.
- the NO produced at the level of the vascular wall and in the surrounding tissues therefore participates in the precise regulation of the vascular tone by adaptation of the blood flow.
- NO has the property of maintaining a low pressure in the pulmonary circulation, which results in a local vasodilator effect, has suggested its use in the context of therapeutic treatments in patients suffering from respiratory diseases , especially in the treatment of acute pulmonary hypertension.
- Patent application WO 92/10228 and other publications describe the use of inhaled NO for the treatment of pulmonary vasoconstriction and asthma.
- This document teaches the use of inhaled NO for therapeutic or diagnostic purposes in the case of respiratory diseases localized in the patient's lungs. It is explained in particular that since NO which enters the bloodstream would be rapidly inactivated by combination with hemoglobin, the effects of inhaled NO would be limited to blood vessels near the site of entry of NO into the circulation , i.e. to the pulmonary microvessels.
- US patent 5,427,797 relates has, meanwhile, use of inhaled NO to inhibit blood coagulation and platelet aggregation that occur in patients with acute respiratory diseases such as Acute Respiratory Distress Syndrome.
- inhaled NO can also be used to prevent or treat inflammations resulting from extra-bodily blood circulation.
- inhaled NO can also be used to prevent or treat inflammations resulting from extra-bodily blood circulation.
- patients suffer from an acute nitric oxide deficiency and thus become more susceptible to inflammatory reactions arising from extra-bodily blood circulation.
- the extra-corporeal circulation leads to the activation of the inflammatory process, in particular the production of cytotoxins and adhesion molecules, and an activation of circulating cells, in particular leukocytes, which migrate towards the vascular endothelium.
- the lungs are not spared since the inflammatory state induces there high arterial pressures due to the obstruction of the microcirculation by aggregates of circulating cells, in particular leukocytes, and a vasoconstriction phenomenon, and this can result in pulmonary edema.
- the present invention therefore relates to the use of nitric oxide (NO) as a medicament or component of an inhaled medicament intended for preventing or combating inflammatory reactions consecutive to an extra-corporeal blood circulation in man or woman. 'animal.
- NO nitric oxide
- the inventor of the present invention has demonstrated the extrapulmonary effects resulting from an inhalation treatment of nitric oxide following an extracorporeal blood circulation.
- the inventor has also demonstrated other systemic effects of nitric oxide, a relaxing effect in the left ventricle of the heart muscle.
- Said drug to be inhaled is administered to humans or animals, preferably at least during part of the operative preparation phase.
- the administration of inhaled NO to the patient (man or animal) from the operative preparation phase that is to say the time phase preceding the first incision and during which the patient is anesthetized and intubated, makes it possible to considerably reduce, or even avoid, any inflammation during the actual operating phase during which the extra-corporeal blood circulation takes place as well as during the postoperative phase.
- said drug to be inhaled is administered by oral or nasal intubation at an effective concentration.
- NO delivery devices that can be used in the context of the present invention are of conventional type; as non-limiting example may be cited the device described in the patent EP 589 751. N has however 0 during the period of extracorporeal circulation, said drug for inhalation may also be administered to the same device blood circulation comprising a membrane oxygenator or operating on any other equivalent principle.
- said medicament to be inhaled is a mixture of gases comprising nitrogen monoxide.
- the drug to be inhaled can also be a vaporization of a NO-containing or otherwise NO-donating substance.
- said gas mixture comprises nitrogen monoxide and at least one compound chosen from the group formed by N 2 , He, Ar, CO 2 , Xe, Kr, O 2 and their mixtures.
- any inert gas, non-oxidizing and without biological activity is suitable.
- the concentration of nitric oxide in said drug to be inhaled is between 0.5 ppm and 80 ppm, preferably between 1 and 40 ppm, and more preferably, between 3 ppm and 10 ppm, advantageously of the order of 5 ppm.
- Patient monitoring is carried out according to the usual procedures, but additional examinations may nevertheless be included, in particular:
- Group 1 is the control group.
- Group 2 is the hypoxia control group in which pigs inhale a hypoxic gas mixture (15% Fi0 2 ) causing pulmonary vasoconstriction and triggering inflammatory reactions.
- Group 3 is the group receiving NO inhaled at a concentration of 40 ppm.
- Group 4 is the group inhaling a hypoxic gas mixture containing 40 ppm NO.
- catheters were placed in the ureters, the aorta and the renal vein and two markers were injected continuously, they are inuiine and para-amino-hippu ⁇ que acid
- the measurement of the clearance of the two markers makes it possible to calculate the blood flow and the glomerular filtration rate.
- urine flow is also measured.
- the pigs receiving inhaled NO have a urinary flow rate, a glomerular filtration rate and a renal blood flow rate much higher than the control control pigs.
- hypoxia-induced vasoconstriction and inflammation reactions cause a marked decrease in renal blood flow.
- This effect of hypoperfusion of the kidney is at least partially offset by the inhalation of NO, which causes an increase in renal blood flow, glomerular filtration rate and urine flow.
- This study therefore confirms the effect of inhaled NO, which makes it possible to oppose vasoconstrictive and inflammatory systemic reactions, in particular by reducing the adhesion of circulating cells. This results in a beneficial effect on the so-called fragile organs, in particular on the renal, hepatic, cardiac, intestinal and neurological functions of the patient.
- the experiment was carried out in four stages: (i) basic physiological measurements, (ii) phase of pulmonary and systemic hypertension induced by an intravenous infusion of phenylephrine (iii) treatment with nitrogen monoxide or nitroglycerine, (iv ) recovery phase by discontinuation of all treatments.
- phase i In order to make the table easier to read, the measurement values for phase i have been deliberately set to 1; those given for phases ii, iii, and iv correspond to the correlation factors.
