- summary: So far, clinical experience in the use of HCQ arises mainly from treatment in patients with systemic lupus erythematosus (SLE), whose long-term effects show multiple benefits. In the COVID-19 patient, possible cardiac involvement is mainly related to 4 factors: 1) underlying heart disease (often silent in older patients); 2) myocardial involvement caused by the infection and the inflammatory response itself, which leads to myocarditis with elevated troponins; 3) acute toxicity probably associated with the use of antimalarials in high doses, more evident in chloroquine treatments and 4) concomitant use of other treatments that, together with HCQ, prolong the corrected QT interval (QTc), with the risk of serious ventricular arrhythmias 3-5 .

It was reported that relative delayed type I interferon (IFN-I) signaling promoted inflammatory monocyte-macrophage accumulation in BALB/c mice infected with SARS-CoV. 43 Consequently, these accumulated mononuclear macrophages produce more monocyte chemoattractants through activating the IFN-α/β receptors and mononuclear macrophage-derived proinflammatory cytokines, such as TNFα, IL-1β and IL-6, induce apoptosis of T cells. signaling or tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-death receptor 5 (DR5) signaling.

- summary: In addition to the cardiotoxic considerations mentioned by Aggarwal, et al (1), relevant cardiovascular side effects and toxicities associated with the use of repurposing drugs for the treatment of COVID-19 have been stated by researchers of cardiovascular disease who stress the risk of QT interval prolongation, thrombocytopenia and anaemia specifically with the use of CQ and HCQ (10). The researchers argue that the presence of underlying cardiovascular disease could represent a partial explanation of the cardiovascular toxicity associated with the use of CQ or HCQ particularly with the combination of macrolides.

- summary: 79 Supplemental glucosamine may likewise up-regulate the type 1 interferon responses to viruses, while exerting anti-inflammatory effects that render it protective in rodent models of sepsis and lung inflammation induced by LPS or cigarette smoke. Although PTX is known to have broad anti-inflammatory activity, it is employed primarily in the treatment of intermittent claudication; by lessening neutrophil activation, PTX renders these cells more distensible, so that they can more readily pass through narrow capillaries in affected legs.

Since some women may fill prescriptions for 311 medications but not use them, our study may misclassify unexposed pregnancies into the HCQ 312 group, thus underestimating any potential effect; however, a large fraction of our cohort filled 313 prescriptions for HCQ throughout the first trimester.

A feared but utterly rare long-term side effect is retinal deposition leading to progressive visual impairment, whereas theoretical risks of arrhythmic disturbances are clinically negligible (i.e., no cardiac screening is required prior to initiation of HCQ treatment).

- summary: Although further evidence is needed to determine the efficacy of aerosolized HCQ in the treatment of COVID-19, low-dose targeted pulmonary delivery represents a safe and potentially preferred delivery method, particularly given the purported mechanisms by which HCQ acts against SARS-CoV-2. After reviewing the prior literature, Klimke et al. tested the safety and tolerability of inhaled HCQ in two healthy human subjects by dissolving HCQ in 0.9% sodium chloride and administering it via commercial nebulizers.

- date: 2020-10-05
- words: 2766

- summary: We hypothesized that HCQ clinical studies would show significant efficacy more often 32 than not for COVID-19; and that efficacy would be greater if HCQ were used earlier in the course of the 33 disease. The third is that there are no unbiased studies showing a negative 86 effect of HCQ treatment of COVID-19.

- summary: The aim of this manuscript is to comprehensively summarize the current knowledge on the antihyperglycemic properties of HCQ and to critically evaluate the potential risks and benefits related to HCQ use in patients with diabetes, even in light of the current pandemic scenario. Besides the well-known contraindications to HCQ use (including known hypersensitivity to 4aminoquinoline compounds), (2, 44) other conditions or circumstances under which HCQ should be contraindicated or used with caution in the context of diabetes include the following: Pre-existing retinopathy/maculopathy, history or risk for macular edema, and concomitant use of other oculo-toxic agents.

- summary: y los que tienen menos probabilidades de beneficiarse (él «demasiado enfermo»), no prestan suficiente atención a las diferencias entre grupos en términos de la duración de los cuidados intensivos necesarios para lograr resultados. Se recomienda aplicar la escala SOFA al menos cada 48 horas sumado al criterio de fragilidad y años de vida saludables salvados estos criterios podrían ser válidos en pacientes con fallo terapéutico a las medidas óptimas y orientar decisiones de deescalamiento de medidas y de nivel de complejidad de atención cuando la demanda potencial supera la oferta (capacidad y capacidades), estas decisiones deben ser tomadas idealmente en junta médica.

- summary: Indeed, in the absence of a clear recommendation for treatment initiation, it is difficult to assume or to invalidate the effect of anti-infective agents on the prognosis of COVID-19 patients. However, it was carried out in a hospital specialized for decades in the Moreover, considering inherent limitation of a descriptive study with a limited sample size (n=132), we could not infer causality in the association between the use of AZI±HCQ and the ameliorated prognosis in COVID-19 patients.

- summary: They showed that CQ could inhibit endosomal TLR signalling after stimulation with nucleic acids at concentration too low to influence the endosomal pH. Under those conditions, CQ blocks endosomal TLR activation by directly interacting with TLR ligands, such as nucleic acids, which changes the nucleic acid secondary structure and prevents their binding to endosomal TLRs (Macfarlane & Manzel, 1998; Ku znik et al, 2011) . In this context, CQ and HCQ decrease replication of viruses such as dengue virus (DENV2), chikungunya virus, hepatitis A and C virus, influenza A virus, Zika virus, severe acute respiratory syndrome coronavirus (SARS-CoV) and Borna disease virus in cellular models (Bishop, 1998; Gonzalez-Dunia et al, 1998; Keyaerts et al, 2004; Vincent et al, 2005; Blanchard et al, 2006; De Clercq, 2006; Eng et al, 2006; Di Trani et al, 2007; Sourisseau et al, 2007; Khan et al, 2010; Ashfaq et al, 2011; Boonyasuppayakorn et al, 2014; Farias et al, 2015; Delvecchio et al, 2016; Shiryaev et al, 2017) .

- summary: At the cellular level, direct and indirect mechanisms of CQ and HCQ are believed to inhibit immune activation by reducing Toll-like receptor signaling and cytokine production and, in T cells, reducing CD154 expression (Schrezenmeier & D€ orner, 2020) ; however, the absence of binding assay studies between the SProtein and hACE2 protein in the presence of HCQ opens the door to two main possibilities (Vincent et al., 2005) : the first possibility revolves around HCQ prevention of terminal glycosylation of hACE2 protein which consequently impacts the final attachment between the SProtein and hACE2 protein, whereas the second possibility revolves around HCQ interaction with the receptor binding domain (RBD) of SProtein, thus preventing its docking on hACE2 receptor. Figure 8 indicates a good protein-ligand stability for all three complexes, with HCQ protein complex showing the lowest RMSD value (0.22 Å) followed by artenimol-protein complex (0.24 Å) and artemisinin-protein complex (0.26 Å).

- summary: One of the drugs prescribed to improve the condition of COVID-19 patients is the antimalarial hydroxychloroquine (HCQ), which recently reported as a supportive drug for shortening the duration of COVID-19 symptoms, reducing inflammatory reactions to infection, impairing the exacerbation of pneumonia and boosting lung imaging findings [3] . Like all medications, HCQ has side effects and may occur in COVID-19 patients.

- summary: In healthy males who received a single HCQ 200 mg oral dose, a mean peak blood HCQ concentration of 0.1296 mcg/ml was achieved in 3.26 h, while a peak plasma HCQ concentration of 0.0503 mcg/ ml was achieved in 3.74 h. Tett and colleagues performed a randomized, crossover study in which the HCQ 155 mg oral tablet was compared to an intravenous infusion of racemic HCQ 155 mg to evaluate the absolute bioavailability of the commercially available HCQ tablet. Maisonnasse and colleagues found that HCQ concentrations in the lung were higher than in plasma, with lung:plasma ratios ranging from 27 to 177 in macaques [25] .

To the best of our knowledge, this study is the first to test the psychiatric effect of HCQ in an animal model, and our results suggest that, in healthy mice, HCQ administration can induce persistent behavioral changes and disrupt gene expression in the brain.

- summary: For the study of HCQ combined with AZM, follow up started when the second of the two co-administered treatments was initiated while still exposed to the first treatment (e.g. when AZM started during a period of HCQ use, or when HCQ started during a period of AZM use). HCQ use was assumed to be chronic in the management of RA, and AZM was assumed an acute prescription for infection treatment, and therefore inferred persistent exposure to AZM was assessed by allowing up to 30 days between dispensing or prescription records.

Therefore, blood levels should ideally reach 1500 ng/ml during the first days upon diagnosis, especially in severe cases with high viral load, and be kept above 500 ng/ ml for the following days (Durcan et al., 2015; Liu et al., 2020b; Yao et al., 2020) .

- summary: Hydroxychloroquine (HCQ), a common antimalarial and lupus drug, has been shown to potentially reduce viral carriage and the number of symptomatic days in COVID-19 patients according to an open-label non-randomized French case study of 36 patients [2] . The above two cases add to the ongoing discussion as to whether HCQ therapy in COVID-19 patients is beneficial for all, especially given how it was paired with another arrhythmogenic agent AZM.

Then CQ/HCQ could also inhibit iron release from endosomes into the cytosol.
