Definitions
- the present invention relates in particular to the treatment of sepsis, systemic inflammatory response syndrome (SIRS) and more particularly to septic shock and SIRS conditions giving similar tables requiring the use of catecholamines after filling or when fast filling phase in case of very sudden aggravation.
- SIRS systemic inflammatory response syndrome
- the present invention also relates to leukemia treatment (for circulating elements).
- the present invention relates to a kit combination of a selenium protein and a selenium compound for the treatment of these syndromes and diseases.
- the present invention also relates to a method of administration which makes it possible to administer effective doses of selenium compounds that are toxic to circulating hyperactive cells and pathogens (bacteria, viruses, fungus and parasites) but beneficial in total for the whole of the organization.
- the invention relates to a delivery device.
- Sepsis is an excessive generalized inflammatory response of the body in response to a bacterial infection, most often, but also parasitic, viral or fungal.
- sepsis is a syndrome and not a disease. Severe sepsis is defined by the presence of one or more organ dysfunctions or failures and signs of peripheral hypofusion, whereas septic shock is defined by the presence of persistent hypotension despite adequate filling associated with the patient. more often to multi-visceral failures. Adequate is generally a filling of 20 to 30 mg / kg. In both cases, an answer excessive or inappropriate body complex, requires the implementation of substitutions of major functions in intensive care to avoid death.
- the interaction of phagocytic cells and endothelium participates in the modification of the endothelium (flip- flap) from a non-adherent, non-inflammatory and non-coagulating endothelium to an adherent, inflammatory and coagulating endothelium and then injured with abrasion of the endothelium surface layer (ESL), formation of nitro-oxygenated reactive derivative - such as peroxynitrite by the joint action of the polynuclear adherents (emission of anion surperoxide) and activated endothelial cells (emission of NO), emission of microparticles, and opening of the tight junctions and suffering of the endothelium.
- endothelium flip- flap
- the objective of the resuscitation is then to bring the subject, once the acute episode passed, to the attractor of homeostasis by gradually releasing survivors of survival related to locums.
- This hyper-inflammatory state most often leads to an acquired immune defect that will cause new infections, possibly with non-dangerous pathogens in a non-immunocompromised subject who may again cause a sepsis reaction.
- the evolution is likely to be then septic shock in septic shock to exhaustion of the subject in a table of marasmus and major undernutrition leading most often to a Therapeutic limitation to an outdated situation where the return to a situation without substitute does not seem possible anymore and corresponds to relentlessness.
- the reactive derivatives of oxygen (polynuclear respiratory oxidation (oxidative metabolism), endothelial cell hyperactivation with NO synthesis, ischemia-reperfusion phenomena and mitochondrial pain) generated by the fight against infectious agents play a major role in endothelial dysfunction, the first step towards multi-visceral failures and death.
- Selenium is a divalent atom in physiopathology. On the physicochemical level, it belongs to column VI which is that of oxygen (chemical family of chalcogens). In fact, chemically and biochemically, small selenium compounds are often toxic oxidizing molecules.
- sodium selenite is one of the most toxic selenium compounds and its toxicity is similar to that of arsenic salts.
- a concentration of 10 ⁇ / L results in cell killing for detached cells (Stewart MS, Free Radic Biol Med 1999 Jan; 26 (1-2): 42-8).
- a selenium concentration of 18 ⁇ / L is observed in cases of fatal intoxication (Nuttall KL, Ann Clin Lab Sci 2006 Autumn, 36 (4): 409-20).
- the lethal dose in humans appears to be in the range of 1.5 to 3 mg / kg.
- Sodium selenite will react preferentially with the disulfide bridges. Its toxicity is greater on free cells than on cellular carpets, and also much more important on hyper-activated cells than on quiescent cells.
- Selenium is incorporated in selenium-like proteins, and is included in the molecule Sodium Selenite, allowing it to be a key element of antioxidant defense in mammals.
- cases of acute poisoning by selenium compounds are completely reversible when they are not fatal, selenium once incorporated into these selenium-containing proteins with an antioxidant action. opposite to that of selenious oxidizing compounds such as selenite.
- mammals and birds have acquired a particular amino acid, selenocysteine, where selenium replace the sulfur in cysteine.
- This replacement is genetically controlled, with the modification of the meaning of the UGA stop codon due to the presence of a neighboring structure and requires energy in the form of ATP.
- the presence of this amino acid at the active site of the selenated enzymes will allow them to have an antioxidant action faster and more robust than their iron precursor and the replacement of selenocysteine by cysteine at the level of active site decreases by a factor of 1000 the effectiveness of these enzymes.
- Selenated proteins are major antioxidant enzymes in mammals. Selenium deficiency is fatal in humans and the knockout model for selenocysteine is lethal.
- selenoprotein-P a protein that is highly conserved among species and exceptionally among selenium-containing enzymes because it contains 9 amino acids selenocysteine (while the others have only one amino acid). selenocysteine) and plasma glutathione peroxidase.
- Selenoprotein-P (Sel-P) accounts for 60% of plasma selenium. It transports biologically active selenium (selenocysteine) between the liver and the tissues and directly contributes to the antioxidant protection of the endothelium by an enzymatic action, likely detoxifying, of the peroxynitrite ion. It has been shown to have a membrane stabilizing role limiting the emission of microparticles.
- the maximum dose of 1000 ⁇ g / day is recommended by Heyland DK (Crit Care 2007; 11 (4): 153), a dose of 4000 ⁇ g / day (55 ⁇ g / kg) administered continuously having had no beneficial effect because in its view of negative effects.
- the administration of 2000 ⁇ g (80 ⁇ g / kg) bolus in sheep was accompanied by positive effects, in contrast to the administration of the same dose continuously, however, it was not possible to conclude on the interest of a bolus administration (Wang Z et al., Shock 2009 Aug; 32 (2): 140-6). In fact, the interest of this bolus administration remains very controversial (Alhazzani, W. et al Crit Care Med 2013 Jun; 41 (6): 1555-64).
- the object of the invention is to propose a solution to this technical problem, and proposes a treatment that targets phagocytes, in particular neutrophils.
- a two-stage administration of compounds, preferably selenic, of different natures at first an antioxidant protein, preferably a selenium protein, then in a second time, an oxidizing compound, preferably a selenium compound, ultra-fast administration (also called flash administration) , and preferably in a few repetitive flashes, and not in a bolus.
- the invention directly and indirectly protects the endothelial cells, limits the adhesion of neutrophils to endothelial cells while allowing to inhibit hyper-activation of phagocytes and particularly immature circulating neutrophils. It can also participate in antibiotic therapy, when the subject is subjected to antibiotic therapy, by a cytotoxic effect on circulating pathogens, including when the subject is resistant to antibiotic therapy.
- Treatment are terms related to therapeutic treatment, and mean delaying the onset of a syndrome or illness, stopping the syndrome or illness, or reversing the syndrome or illness .
- the syndrome is sepsis; the subjects concerned by the invention therefore include subjects at the initial phase of sepsis, diagnosed in particular by a decrease in circulating selenoprotein-P or by any other biomarker of sepsis, and / or subjects in whom the sepsis is already diagnosed or recognized.
- a subject is considered to be effectively treated with sepsis if he or she shows an observable and / or measurable decrease in nitrogen oxide and / or lactate production, and / or a significant decrease in the mortality rate as well as a decreased severity of visceral failures (which can be measured by the SOFA score).
- These evaluation parameters of an effective treatment are easily measurable by routine procedures known to the physician.

- the device according to the invention provides a source of energy for generating a pressure and / or a fluidic flow, while offering the user a tactile and / or audible feedback of the fluidic pressure generated, which allows the user to modulate the pressure and / or flow of the fluid.
- the injection system of the present invention is capable of providing both a low flow rate and / or low pressure delivery mode as well as a high flow and / or high pressure delivery mode.
- the injection system of the device comprises a fluid control module in active connection with an injector connected to a syringe.
- the syringe is in fluid connection with an automatic valve of the fluid control module, which is also in fluid communication with a contrast source through an intermediate flow chamber.
- the dropper chamber preferably comprises a fluid level detection mechanism.
- a preferably automated valve is also in communication with a first lumen inlet of a pressure isolation valve. The valve prevents saline and / or contaminated fluids from entering the syringe and allows the control module to stop the flow of fluid from the syringe quickly at any pressure and / or flow rate. This ability to immediately stop the flow of injection fluid at any pressure and flow rate substantially eliminates the effects of system compliance and allows for both slow administration of a compound and both flash administration of another compound.
- the invention also relates to a kit as described above, for its use in the treatment of sepsis and / or systemic inflammatory response syndrome (SIRS), severe sepsis, septic shock, cancer (in particular leukemia, lymphoma or solid tumor cancer), said use implementing the method of administration described above.
- the treated subject may be in septic shock.
- the treated subject may be in a multi-visceral failure state.
- the present invention relates in particular to a kit for its use in the treatment of sepsis and / or systemic inflammatory response syndrome (SIRS) comprising on the one hand an antioxidant selenium protein, and on the other hand a compound selenium, the selenium antioxidant protein being intended to be administered slowly before administration of the selenium compound, which is to be administered after the selenium protein ultra-fast, preferably repeated flash.
- SIRS systemic inflammatory response syndrome
- the terms sepsis and SIRS as used in the invention may correspond to septic shock and SIRS conditions giving similar tables requiring the use of catecholamines after filling or during rapid filling phase in case of aggravation very deadly. Severe sepsis may be indicated by the presence of one or more organ dysfunctions or failures and signs of peripheral hypofusion.
- Severe sepsis is an inflammatory systemic response to an infection associated with visceral failure, hypo-infusion or hypotension, including lactic acidosis, oliguria, or altered mental status.
- Septic shock can be revealed by the presence of persistent hypotension despite adequate filling. Adequate is generally a filling of 20 to 30 mg / kg.
- Septic shock is often characterized by an inflammatory systemic response to an infection associated with collapse (hypotension) of more than one hour despite adequate filling and in the absence of other causes of hypotension. (Hypotension is later in children and other signs should be considered in pediatrics).
- Hypotension is defined as: systolic blood pressure ⁇ 90 mmHg, mean arterial pressure ⁇ 60 mmHg, or decrease> 40 mmHg in adults or +/- 2 SD below that of reference in children).
- Severe sepsis like septic shock, is a syndrome based on the clinical reflection of visceral failure (s), itself (s) consequence of the metabolic response to aggression.
- the inflammatory systemic response is a descriptive term used to describe the presence of a generalized inflammatory response regardless of its cause, and is recognized by a complex set of signs. According to the latest consensus conference, according to the "2001 SCCM / ESICM / ACCP / ATS / SIS International Sepsis Conference Definitions", these signs are currently defined as follows:
- CRP C reactive plasma protein
- multi-visceral failure corresponds to a clinical syndrome characterized by an acute and potentially reversible dysfunction of an organ or a large function, not directly involved in the initial pathological process.
- Multi-visceral failure is usually associated with hypotension (systolic blood pressure ⁇ 90 mmHg or reduction> 40 mmHg from baseline in the absence of other cause).
- the multi-visceral failures are readily based on the SOFA (Sepsis Related Organ Failure Assessment) score (Table 1), the first two ranks are associated with dysfunctions, the last two with failures. They then associate themselves most often with the need to implement locum to keep the subject alive. This may include (i) ventilating by a device to assist breathing, (ii) infusion and catecholamine administration to maintain satisfactory blood pressure and blood flow, (iii) dialysis to replace the kidneys, (iv) transfusion of blood and platelets. These substitutions, and their supervision, will have a very important impact in the cost of treating subjects in septic shock.
- SOFA Sepsis Related Organ Failure Assessment
- SOFA score is one of the failure scores the most used.
- the definition of sepsis was changed in 2016 and is defined as life-threatening organ dysfunction caused by a deregulated response to infection.
- the Organ dysfunction can be assessed by increasing the SOFA by 2 points (or more) that is associated with a morality of more than 10%.
- Septic shock should be defined as subjects in sepsis where there is particularly pronounced circulatory failure, with cellular and metabolic abnormalities that are associated with higher mortality than in sepsis alone (Singer M and JAMA 2016; 315 (8 ): 801-810).
- Lactate plasma concentration and its evolution is a late but commonly accepted marker of the occurrence of sepsis and the monitoring of the efficacy of the management of septic shock (or severe sepsis).
- other recognized markers are those of visceral failure surveillance as listed in the 2001 consensus conference and in the SOFA score.
- Other markers such as nitrogen oxide NO, cytokines, growth factors in particular endothelium, microparticles, receptor assays are used but in the context of research. The determination of selenoprotein-P has been proposed as an early marker of sepsis and its severity.
