Automédication et conseil pharmaceutique en période de pandémie de COVID-19 à Oran / Self-medication and pharmaceutical advice during the COVID-19 pandemic in Oran

Introduction : L'épidémie de Covid-19 a créé une psychose et une anxiété généralisées. Cela pourrait être lié, d'une part, à la mortalité élevée observée dans le monde, et d'autre part, à l'absence d'une thérapie spécifique. Face à cette situation, de nombreuses substances ont été utilisées sans avis médical. L'objectif de cette étude était d'évaluer les pratiques de l'automédication en situation de Covid-19 à Oran. Matériel et méthodes : Il s'agit d'une enquête transversale observationnelle réalisée par questionnaire électronique anonyme (googleforms) et distribué, par e-mail, à des pharmaciens adhérents à la section ordinale régionale des pharmaciens d'Oran. Les réponses ont été analysées par le logiciel Statistical Package for the Social Sciences (SPSS). Résultats : Au total, 69 réponses ont été obtenues. La proportion de pharmaciens ayant perçu une tendance à la hausse de l'automédication était de 58,0%. Environ le quart des pharmaciens (22,9%) avaient constaté une augmentation de l'automédication à l'hydroxychloroquine ; néanmoins, aucune toxicité secondaire à l'usage de ce médicament n'a été observée. En cette situation d'épidémie de Covid-19, 91.3% de l'échantillon d'étude avaient constaté une augmentation du recours aux vitamines et compléments alimentaires, avec une consommation fréquente de la vitamine C à 1gr/j ainsi que d'autres complexes vitaminiques à base de vitamine D, vitamine B9 et fer chez la femme enceinte ou allaitante. Conclusion : Notre étude a montré qu'en période de Covid - 19 la tendance à l'automédication a augmenté. L'automédication à l'hydroxychloroquine a été observée durant cette pandémie néanmoins l'usage d'autres substances telles que les vitamines et les compléments alimentaires était plus fréquent.

Introduction : the epidemic of Covid-19 has created generalized psychosis and anxiety. This could be linked, on the one hand to the high mortality observed in the word, and the other hand to the absence of specific therapy. Faced with this situation, many substances have been used without medical advice. The objective of this study was to evaluate the practice of self-medication in COVID-19 situation in Oran. Materials and methods : this is an observational cross sectional survey carried out by an anonymous electronic questionnaire and distributed, by email, to pharmacist belonging to the regional ordinal section of pharmacist in Oran. The answers were analysed by the software Statistical Package for the Social Sciences (SPSS). Results : A total of 69 responses were obtained. The proportion of pharmacists who noticed an increasing trend in self-medication was 58,0%. About a quarter of pharmacist had observed an increase in selfmedication with hydroxychloroquin, at least no toxicity secondary to the use of this drug was observed. In this COVID19 epidemic situation, 91.3% of the study sample noted an increase in the use of vitamins and food supplements with frequent consumption of vitamin C at 1g/day as well as other vitamin comlexes based on vitamin D, vitamin B9 and iron for pregnant or breastfeeding women. Conclusion : Our study showed that during COVID-19 the tendency to self-medication increased. Self-medication with hydroxychloroquin was observed during this pandemic, although the use of other substances such as vitamins and food supplements was more frequent.

Identification of chemical constituents of Xiaoer Chiqiao Qingre Granules based on UHPLC-LTQ-Orbitrap-MS/MS and network pharmacology analysis / 中国中药杂志

This study aimed to qualitatively analyze the chemical components in Xiaoer Chiqiao Qingre Granules(XRCQ) by UHPLC-LTQ-Orbitrap-MS/MS and identify its material basis. The absorbed components in plasma were combined for exploring the potential action mechanism by integrated network pharmacology. ACQUITY UPLC HSS T3(2.1 mm×100 mm, 1.8 μm) column and mobile phase system of 0.1% formic acid solution(A)-acetonitrile(B) were used for gradient elution, followed by high resolution liquid chromatography-mass spectrometry in both positive and negative ion scanning modes. According to the precise relative molecular mass and MS/MS fragment ions, a total of 124 chemical components were identified in XRCQ by the comparison with references and literature reports, among which 29 compounds were completely confirmed by comparison with reference substances. Then, the main absorbed components of XRCQ in plasma were also analyzed and clarified by UHPLC-LTQ-Orbitrap-MS/MS. BATMAN-TCM and SwissTargetPrediction were used for target prediction of absorbed components in plasma. Following the plotting of association network with Cytoscape 3.8.2, the core targets were subjected to GO and KEGG pathway enrichment analysis and a component-target-pathway network was constructed. A total of eight main targets of XRCQ against fever in children were obtained together with eight absorbed components in plasma, including glycyrhydinic acid, hesperidin, emodin, reticuline, daidzein, magnolignan C, magnolignan A, and magnolaldehyde D. It was inferred that XRCQ might improve alimentary system abnormality, inflammatory response, oxidative stress, and endocrine disorder through tumor necrosis factor, PI3 K-AKT, and other signaling pathways. The present study comprehensively expounded the chemical profiles of XRCQ and the main absorbed components in plasma and predicted the potential mechanism of XRCQ based on integrated network pharmacology, which has provided certain theoretical reference for the clinical application of XRCQ.

A study to evaluate the correlation between serological profile and histopathology of lupus nephritis

Background: Systemic lupus erythematosus is an autoimmune disease of unknown etiology, characterized by the involvement of multiple organ systems. Organ damage is mediated by tissue binding autoantibodies and immune complexes. High anti-dsDNA titer and low serum complement levels (C3, C4) correlate with disease activity of SLE, especially with lupus nephritis (LN). Aim of the study: To evaluate the correlation between a serological profile (anti-dsDNA, serum C3, and C4) and histopathology of lupus nephritis and to find out the class of LN which has a significant correlation with the serological profile. Materials and methods: This retrospective study was conducted in the Department of Nephrology, Kilpauk Medical College and Hospital, Chennai between 2013-2017 with 50 ANA positive female SLE patients with evidence of lupus nephritis (proteinuria, microscopic hematuria or increased serum creatinine). Serological profile (anti-dsDNA, serum C3, and C4) and renal biopsy were done in all patients. Results: Of 50 patients, 35 (70%) had class IV lupus nephritis, 7 (14%) class II, 4(8%) class V and 4 patients (8%) had class IV and V on renal biopsy. The prevalence of anti dsDNA was 97.1% in LN and 97.4% (38 of 39 pts) in proliferative LN (p<0.001). The C3 level was low in 68% of patients with LN and 84.6% with proliferative LN (p <0.001). C4 level was low in 74% of patients with LN and 87.2% with proliferative LN (p <0.001). In our study, 72% (28 of 39 pts) of the patients with Vasudevan Chelliah, Ramesh Subramanian. A study to evaluate the correlation between serological profile and histopathology of lupus nephritis. IAIM, 2019; 6(4): 36-41. Page 37 proliferative LN (class IV, IV and V) had the combination of anti-dsDNA positivity, low C3,and low C4 levels but none of the patients with class II or class V LN had this combination of serology. Conclusion: In our study, the serological profile of SLE had a significant correlation with histopathology of lupus nephritis. Anti-dsDNA, low C3, and low C4 had a significant independent correlation (p<0.05) with proliferative LN (class IV, IV and V).

Neuroprotective effects of salidroside on complement composition in cerebral ischemia/reperfusion injury rats / 中国药理学通报

Aim To study the effects of salidroside on the complement components in MCAO rats and to further explore the mechanism of neuroprotection of salidroside. Methods Forty-five healthy male Sprague-Dawley rats were randomly divided into sham operation (Sham) group, model (MCAO) group, and salidroside (MCAO + Sal) group. Rats were administered salidroside, or vehicle, daily for 6 days, after middle cerebral artery occlusion( MCAO) 2 h and reperfusion 1 h. The protein expressions of C3 and brain tissue mitochondrial Bax, Bcl-xl were detected by Western blot. The mRNA expressions of Clqa, Clqb, Clqc, C2, C3, C3a, C4a, C5a, Cfh, Cfd were detected by qPCR. Gene chip technology was used for detection. The expressions of C3 and NeuN were detected by im-munofluorescence. Results Compared with MCAO group, salidroside could reduce the protein expression of Bax protein in mitochondria and promote the expression of Bcl-xL protein after salidroside treatment. By gene chip cluster analysis and qPCR detection, salidroside could inhibit the expression of complement-related genes such as Clqa, Clqb, Clqc, C2, C3, C3a, C4a, C5ar, Cfh and Cfd mRNA. According to West-em blot and immunofluorescence, salidroside inhibited the expression of C3 and promoted the expression of NeuN. Conclusions Salidroside can inhibit the complement component, especially the action of the complement central component C3, exerting neuroprotective effects on MCAO rats.

A retrospective analysis of clinicopathology and plasma complement activation in C3 glomerulonephritis / 中华肾脏病杂志

Objective To study the clinicopathological features of C3 glomerulonephritis and the associations between plasma complement fragments level and clinical manifestations.Methods The clinical and pathological data of the 12 patients with C3 glomerulonephritis in our division from January 1999 to June 2010 were analyzed retrospectively.Concentrations of plasma factor B,Ba,C3,C3a,C4a and C5a were detected by commercial available sandwich ELISA kits on the day of renal biopsy.Results Ten of the 12 patients were C3 glomerulonephritis without MPGN,and the rest 2 were C3 glomerulonephritis with MPGN.All the patients presented proteinuria.Two of the 10 C3 glomerulonephritis patients without MPGN presented nephrotic range proteinuria,6 with microhematuria,1 with gross hematuria,and 2 with renal insufficiency.One of the 2 C3 glomerulonephritis patients with MPGN presented nephrotic range proteinuria,accompanied by microhematuria,hypertension and renal insufficiency.The other patient showed moderate proteinuria with normal renal function.Most of C3 glomerulonephritis patients without MPGN showed mild mesangial proliferative glomerulonephritis,and 4/10 patients had various degree cresentic formation.One C3 glomerulonephritis patient with MPGN had 47.1％ cresentic formation.The concentration of plasma C3 in C3 glomerulonephritis patients was normal,while the plasma factor B was significantly decreased,and the concentrations of plasma Ba,C3a,C4a and C5a were significantly elevated.The concentration of plasma Ba was positively correlated with the proteinuria level,while the concentrations of plasma C3a,C4a and C5a were not correlated with the levels of proteinuria or plasma creatinine.Conclusions Majority of these 12 patients were C3 glomerulonephritis without MPGN,manifests as nephritic syndrome clinically and mild mesangial proliferative glomerulonephritis histopathologically.Complement activation via alternative pathway may play an important role in the pathogenesis of C3 glomerulonephritis.

Infection and Innate Immunity / 소아과

As known by other name (natural immunity), the innate immune system comprises all those mechanisms for dealing with infection that are constitutive or built in, changing little with age or with experience of infection. Though in some ways less sophisticated than adaptive immunity, innate immunity should not belittled, since it has evidently protected thousands of species of invertebrates sufficiently to survive for up to 2 billion years. In the innate immune system, molecules of both cellular and humoral types are involved, corresponding to the need to recognize and dispose of different types of pathogen, to promote inflammatory responses and to interact to the adaptive immune system. A major features of innate immunity are the presence of the normal gut flora, complements, macrophages, dendritic cells, natural killer cells and many cytokines that can block the establishment of infection. Both phagocytic cells and complement system have tremendous potential for damaging host cells, but fortunately they are normally only triggered by foreign materials, and usually most of their destructive effects are focussed on the surface of these or in the safe environment of the phagolysosome. This article addreses the comprehensive mechanisms of the major components of the innate immune system to prevent the infection.

A Study of the Anti-porcine Endothelial Immunoglobulin and Complement in the Sera of End-stage Renal Failure Patients and End- stage Liver Failure Patients / 대한이식학회지

PURPOSE: Shortage of donor organs is one of the major barriers of clinical organ transplantation. To overcome the shortage, a huge amount of research into xenotransplantation has been done worldwide. The major problem in xenotransplantation is hyperacute rejection, a rapid and violent rejection that damages the graft within minutes or hours. Hyperacute rejection is mediated by the components of natural immunity, most notably natural antibodies and complements. METHODS: The aim of this study is to explore the quantitative amounts of the natural antibodies and complements in the sera of patential recipients with respect to their diseases. The samples of blood from the 10 patients with end stage renal or liver disease were obtained for the assay of natural xenoreactive antibodies. Natural anti-porcine endothelial antibodies (IgM and IgG) were measured by ELISA with porcine aortic endothelial cells in culture as targets. Quantitative analysis of C3 was also done with the ELISA with porcine endothelial cell in culture. RESULTS: Optical densities measured with the ELISA for IgM or IgG natural antibodies in the blood from the different three groups (healthy volunteer, renal failure patients, and liver failure patients) to cultured porcine aortic endothelial cells were not statistically (P>0.05) different among the three groups. Moreover, those for complement (C3) to porcine endothelial cells were not statistically (P>0.05) different among the groups. CONCLUSION: Further efforts should be made toward modifying the technique for removal of specific natural antibodies and complements for the successful xenotransplantation regardless the disease entities of potential recipient candidates.

Exudative pleurisy induced by cobra venom factor in rats / 中国药理学通报

AIM To establish the model of exudative pleurisy induced by alternatively activating complement and to study protection of anti inflammatory drugs on it. METHODS Purified cobra venom factor (CVF) was injected into the pleura, and then exudate volumn, total leukocyte count, protein content and histamine concentration were determined. RESULTS CVF, injected into rat pleura at dose of 0 08～2 mg?kg -1 , induced exudative inflammation in dose dependent and time dependent manner. Both diphehydramine and isoprenaline reduced significantly exudate volume, total leukocyte count, protein content and histamine concentration, while indomethacin, dexamethasone and cyclophosphamide also reduced exudate volume, total leukocyte count and protein content, although they did change the release of histamine. DLF, one of the toxic components in cobra venom, potentiated CVF induced inflammation. CONCLUSION CVF can induce significantly exudative pleurisy sensitive to anti inflammatory agents. DLF has augmentation on CVF induced inflammation.
