Abstract

Multisystem inflammatory syndrome in children (MIS-C) is a rare and severe condition that follows benign COVID-19. We report autosomal recessive deficiencies of OAS1, OAS2, or RNASEL in five unrelated children with MIS-C. The cytosolic double-stranded RNA (dsRNA)-sensing OAS1 and OAS2 generate 2'-5'-linked oligoadenylates (2-5A) that activate the single-stranded RNA-degrading ribonuclease L (RNase L). Monocytic cell lines and primary myeloid cells with OAS1, OAS2, or RNase L deficiencies produce excessive amounts of inflammatory cytokines upon dsRNA or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stimulation. Exogenous 2-5A suppresses cytokine production in OAS1-deficient but not RNase L-deficient cells. Cytokine production in RNase L-deficient cells is impaired by MDA5 or RIG-I deficiency and abolished by mitochondrial antiviral-signaling protein (MAVS) deficiency. Recessive OAS-RNase L deficiencies in these patients unleash the production of SARS-CoV-2-triggered, MAVS-mediated inflammatory cytokines by mononuclear phagocytes, thereby underlying MIS-C. © 2023 American Association for the Advancement of Science.

Abstract

Circulating autoantibodies (auto-Abs) neutralizing high concentrations (10 ng/ml; in plasma diluted 1:10) of IFN-α and/or IFN-ω are found in about 10% of patients with critical COVID-19 (coronavirus disease 2019) pneumonia but not in individuals with asymptomatic infections. We detect auto-Abs neutralizing 100-fold lower, more physiological, concentrations of IFN-α and/or IFN-ω (100 pg/ml; in 1:10 dilutions of plasma) in 13.6% of 3595 patients with critical COVID-19, including 21% of 374 patients >80 years, and 6.5% of 522 patients with severe COVID-19. These antibodies are also detected in 18% of the 1124 deceased patients (aged 20 days to 99 years; mean: 70 years). Moreover, another 1.3% of patients with critical COVID-19 and 0.9% of the deceased patients have auto-Abs neutralizing high concentrations of IFN-β. We also show, in a sample of 34,159 uninfected individuals from the general population, that auto-Abs neutralizing high concentrations of IFN-α and/or IFN-ω are present in 0.18% of individuals between 18 and 69 years, 1.1% between 70 and 79 years, and 3.4% >80 years. Moreover, the proportion of individuals carrying auto-Abs neutralizing lower concentrations is greater in a subsample of 10,778 uninfected individuals: 1% of individuals 80 years. By contrast, auto-Abs neutralizing IFN-β do not become more frequent with age. Auto-Abs neutralizing type I IFNs predate SARS-CoV-2 infection and sharply increase in prevalence after the age of 70 years. They account for about 20% of both critical COVID-19 cases in the over 80s and total fatal COVID-19 cases. © 2021 The Authors, some rights reserved.

Abstract

The accreditation process of french health care organisations has been based on a combination of self-assessment by hospitals and accreditation survey conducted by surveyors, both making use of the same evaluation criteria. Self-assessment and on-site surveys were therefore based on very similar principles, and self-assessment was considered primarily as a reflective practice to be compared to external assessment. In an effort to improve evaluation mechanisms, the V2014 process replaces self-assessment with the logging of a Quality Account, …

6. Pharmacological properties of AR-C239, 2-[2-[4(o-methoxyphenyl)-piperazine-1-Yl]-ethyl]4,4-dimethyl-1,3(2H-4H) isoquinolinedione, a new alpha-adrenoceptor blocking drug

Abstract

In pentobarbital-treated dogs and rats, AR-C239, a new and potent alpha-adrenoceptor blocking drug, competitively antagonized pressor responses to adrenaline and inhibited pressor responses to noradrenaline, phenylephrine, tyramine, and dimethylphenylpiperazinium. Injected intravenously into closed-chest dogs, AR-C239 (3-50 micrograms/kg) induced a progressive fall in blood pressure, heart rate, and sympathetic nerve activity. The drug appears to be devoid of direct vasodilator action, and the fall in blood pressure results from the peripheral alpha-blockade. AR-C239 did not change the tachycardia induced by stimulation of the cardiac nerve in dogs and, at least in this preparation, seems to be a specific alpha 1-adrenoceptor blocking drug. When administered into the cisterna magna of dogs, AR-C239 did not have any centrally mediated cardiovascular actions and heart rate. AR-C239 did not modify the functioning of the baroreflex arc. Due to its specificity for alpha 1-Adrenoceptors, AR-C239 may be useful for characterizing alpha-adrenoceptors.

Abstract

Objectives: Accreditation in France relies on a mandatory 4-year cycle of self-assessment and a peer review of 82 standards, among which 14 focus priority standards (FPS). Hospitals are also required to measure yearly quality indicators (QIs-5 in 2010). On advice given by the accreditation committee of HAS (Haute Autorité en Santé), based on surveyors proposals and relying mostly on compliance to standards, accreditation decisions are taken by the board of HAS. Accreditation is still perceived by hospitals as a burdensome process and a simplification would be welcomed. The hypothesis was that a more limited number of criteria might give sufficient amount of information on hospitals overall quality level, appraised today by accreditation decisions., Design: The accuracy of predictions of accreditation decisions given by a model, Partial Least Square-2 Discriminant Analysis (PLS2-DA), using only the results of FPS and QIs was measured. Accreditation decisions (full accreditation (A), recommendations or reservation (B), remit decision or non-accreditation (C)), results of FPS and QIs were considered qualitative variables. Stability was assessed by leave one out cross validation (LOOCV)., Setting and Participants: All French 489 acute care organisations (ACO) accredited between June 2010 and January 2012 were considered, 304 of them having a rehabilitation care sector (RCS)., Results: Accuracy of prediction of accreditation decisions was good (89% of ACOs and 91% of ACO-RCS well classified). Stability of results appeared satisfactory when using LOOCV (87% of ACOs and 89% of ACO-RCS well classified). Identification of worse hospitals was correct (90% of ACOs and 97% of ACO-RCS predicted C were actually C)., Conclusions: Using PLS2-DA with a limited number of criteria (QIs and FPS) provides an accurate prediction of accreditation decisions, especially for underperforming hospitals. This could support accreditation committees which give advices on accreditation decisions, and allow fast-track handling of 'safe' reports.

Abstract

Objectives: Because the synthesis of aldosterone is mainly modulated by angiotensin II through type I receptor stimulation and because converting enzyme inhibition (CEI) does not modify aortic extracellular matrix in old normotensive rats, the aim of the present study was to determine whether inhibition of aldosterone formation was able to prevent aortic fibrosis in old Sprague-Dawley normotensive rats., Background: We have previously shown that long-term aldosterone antagonism prevents the age-related increase in aortic collagen accumulation in young spontaneously hypertensive rats, independent of blood pressure changes. In contrast, we reported that the positive effects of CEI in the prevention of aortic collagen accumulation were related to the inhibition of angiotensin II actions on angiotensin II type I receptors., Methods: For this purpose, we studied the histomorphometric and stiffness (echo-tracking technique) changes of an eight-week treatment with the aldosterone antagonist spironolactone by comparison with placebo., Results: At the end of treatment, spironolactone in conscious animals did not change intra-arterial blood pressure, aortic and carotid wall thickness, and cardiac weight. Cardiac collagen density and, to a lesser extent, carotid collagen and elastin densities and contents were significantly decreased in association with an increase of carotid distensibility., Conclusions: These results show that in old normotensive rats, spironolactone can markedly prevent cardiac and, to a lesser extent, arterial fibrosis and improve arterial stiffness, despite a lack of hypotensive effect.

Abstract

The purpose of the present study was to determine the effects of chronic sinoaortic denervation on the mechanical properties and composition of the abdominal aorta in Wistar rats. We used a high-resolution echotracking system to determine in situ under physiological conditions of blood flow and arterial wall innervation the aortic diameter-, compliance-, and distensibility-pressure curves in 16-week-old anesthetized rats that had been denervated at 10 weeks of age for 6 weeks (n = 8). Compared with sham-operated rats (n = 8) we observed a marked reduction of baroreflex response and increase in overall mean blood pressure variability as measured by standard deviation and spectral analysis in sinoaortic-denervated rats. Mean blood pressure was not affected by sinoaortic denervation in both conscious and anesthetized rats. Sinoaortic denervation significantly shifted the distensibility-pressure curve toward lower levels of distensibility, indicating a decreased aortic distensibility for a given level of arterial pressure. Sinoaortic denervation produced a significant increase of aortic wall cross-sectional area and collagen content, one of the less-distensible components of the arterial wall. These results suggest that intact arterial baroreceptors are necessary for maintaining normal functional and structural properties of large arteries in rats. The reduction in arterial distensibility in chronic sinoaortic-denervated rats may have resulted from different factors, including the initial hypertensive phase, aortic wall hypertrophy, and increase in collagen content. The changes in aortic wall structure and related reduction in aortic distensibility, in addition to other mechanisms, might have been direct consequences of an increased blood pressure variability.

Abstract

In pentobarbitalized closed-chest dogs, nicergoline (10--100 microgram/kg, i.v.) reduced blood pressure, heart rate, and splanchnic nerve activity. Intracisternal administration of nicergoline (3 microgram/kg) only reduced splanchnic nerve activity. In open-chest dogs, nicergoline reduced blood pressure, cardiac output, and total peripheral resistance but did not change heart rate. In pithed rats treated with a beta-adrenoceptor-blocking agent, nicergoline reduced the pressor responses to noradrenaline and adrenaline. Nicergoline slightly attenuated the pressor responses of dogs to noradrenaline and tyramine and, in addition, reversed the hypertension induced by adrenaline and dimethylphenylpiperazinium. Nicergoline (100 microgram/kg) increased the tachycardia induced in dogs by stimulation of the right cardiovascular nerve and prevented the inhibitory effect of clonidine on this response. However, nicergoline only partially antagonized the effect of clonidine once it was fully established. Nicergoline did not antagonize the hypotensive and bradycardic effects of clonidine when they were established. Nicergoline did not affect the vagally mediated bradycardia evoked by carotid nerve stimulation in beta-adrenoceptor-blocked dogs. The compound did not change blood pressure in Cl spinal cord transected dogs. In conclusion, nicergoline appears to decrease blood pressure by blocking alpha-adrenoceptors and, at least at some doses, by a central inhibition of the sympathetic tone. Nicergoline appears to be a preferential alpha 1-adrenoceptor-blocking agent.

Abstract

In pentobarbital-treated dogs clonidine (10 micrograms/kg) reduced the increase in heart rate caused by electrical stimulation of the cardiac nerve (1-10 Hz). We studied the actions of six alpha-adrenoceptor blocking drugs. Yohimbine (0.3 mg/kg) and phentolamine (1 mg/kg) potentiated the effects of nerve stimulation and antagonized the inhibitory effects of clonidine. Piperoxan (1 mg/kg) increased the response to nerve stimulation but antagonized the effects of clonidine only at the lowest frequency of stimulation. Thymoxamine (1 mg/kg) and prazosin at high doses (1 mg/kg) also antagonized the effects of clonidine but failed to increase the positive chronotropic response to stimulation of the cardiac nerve. AR-C239, a new and potent alpha-adrenoceptor blocking agent, changed neither the response to nerve stimulation nor the inhibitory effect of clonidine. The effects of all these drugs were observed at doses which reduced or reversed the pressor response to adrenaline. Therefore, our results afford further evidence for a dissimilarity between postsynaptic and presynaptic alpha-adrenoceptors in the dog. In addition, they show that the failure of an alpha-adrenoceptor blocking compound to increase the response to nerve stimulation does not necessarily indicate a lack of presynaptic alpha-adrenoceptor blockade.
