Salim E, Ilmi H, Widyawaruyanti A, Oka N. Design and synthesis of hydroxychloroquine-sugar conjugates as promising antimalarial agents. Bioorg Med Chem Lett 2025; 125-126:130289. [PMID: 40449854 DOI: 10.1016/j.bmcl.2025.130289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2025] [Revised: 05/11/2025] [Accepted: 05/27/2025] [Indexed: 06/03/2025]
Abstract
Novel hydroxychloroquine (HCQ)-sugar conjugates were evaluated for their antimalarial activity against chloroquine-sensitive (Pf3D7) and multi-resistant (PfDd2) strains of Plasmodium falciparum, cytotoxicity, and hydrolytic stability. HCQ-galactose conjugate with a 1,2-orthioester linkage exhibited the highest activity against Pf3D7 (IC50 value of 0.018 ± 0.001 μg/mL). Per-O-acetyl-β-d-glucopyranosyl-HCQ exhibited the highest activity against PfDd2 (IC50 = 0.20 ± 0.02 μg/mL), while also maintaining comparable activity against Pf3D7. Orthoester-linked conjugates were gradually hydrolyzed in human serum, resulting in HCQ release, which may contribute to their high activity. Glycosidic bond-linked conjugates showed high hydrolytic stability, retaining a certain level of activity, possibly without releasing HCQ. Toxicity assessments using the BHK21 cell line indicated significantly lower cytotoxicity for all HCQ-sugar conjugates compared to HCQ.

Lee SH, Park KE, Kwon SC, Ok SH, Ahn SH, Sim G, Sohn JT. Chloroquine Inhibits Contraction Elicited by the Alpha-1 Adrenoceptor Agonist Phenylephrine in the Isolated Rat Aortas. Int J Mol Sci 2025; 26:4556. [PMID: 40429701 PMCID: PMC12111159 DOI: 10.3390/ijms26104556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2025] [Revised: 05/07/2025] [Accepted: 05/07/2025] [Indexed: 05/29/2025] Open
Abstract
Although chloroquine appears to inhibit the alpha-1 adrenoceptor, whether the chloroquine-mediated inhibition of phenylephrine-induced contraction is associated with the blockade of alpha-1 adrenoceptors remains unknown. This study examined the effect of chloroquine on contractions elicited by the alpha-1 adrenoceptor agonist phenylephrine in isolated rat aortas and determined the underlying mechanism. The effects of chloroquine and the alpha-1 adrenoceptor inhibitor prazosin on phenylephrine-elicited contractions were examined. The effects of the irreversible alpha-adrenoceptor inhibitor phenoxybenzamine followed by washout with fresh Krebs solution, as well as combined treatment with chloroquine and phenoxybenzamine followed by washout with fresh Krebs solution, on phenylephrine-induced contraction were investigated. Chloroquine and prazosin inhibited phenylephrine-induced contractions. However, pretreatment with prazosin eliminated the chloroquine-induced inhibition of contractions elicited by phenylephrine. Additionally, pretreatment with chloroquine and phenoxybenzamine followed by washout produced a higher contraction elicited by phenylephrine than pretreatment with phenoxybenzamine alone followed by washout. Although chloroquine did not affect the contraction induced by KCl in the endothelium-denuded aorta, it inhibited phenylephrine-induced protein kinase C (PKC) and myosin light-chain (MLC20) phosphorylation and Rho-kinase membrane translocation. These results suggest that chloroquine inhibits vasoconstriction elicited by phenylephrine via alpha-1 adrenoceptor inhibition, which is mediated by decreased MLC20 phosphorylation, the attenuation of PKC phosphorylation, and Rho-kinase membrane translocation.

High-dose hydroxychloroquine induces changes in low-frequency brain oscillations in electrocorticographic records not concurrent with alterations in cardiac, hepatic, and renal function in wistar rats. Biomed Pharmacother 2025; 186:117980.

Abstract
The toxicity of hydroxychloroquine (HCQ) can impact the function of vital organs, leading to ocular and cardiovascular damage. This study aims to evaluate the toxicity of HCQ through electrocorticographic evaluation and blood biochemical parameters in Wistar rats. The animals received a dose of HCQ of 350 mg/kg via gavage every 12 hours for periods of 24, 48, 72 and 96 hours, with each group consisting of n = 9. After treatment, the animals underwent surgery to implant electrodes in the motor cortex region and subsequently underwent bipolar electrocorticography. The electrodes for acquiring electrocardiographic recordings were fixed in the D II position and blood samples were analyzed for liver and kidney function. The results demonstrated that high doses of HCQ altered electrocorticographic features, decreased cardiac activity throughout treatment, and significantly elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. However, assessment of renal function, as indicated by serum creatinine levels, revealed no significant changes. These results suggest that exposure to high doses of HCQ in rats may disrupt the structures and functions of vital organs.

Abstract
Hydroxychloroquine (HCQ) is an antimalarial drug that has historically been used to treat and prevent malaria. However, its mechanism of action has not yet been fully elucidated. HCQ affects various cellular and molecular pathways through different mechanisms. HCQ has also been shown to be a disease‑improving agent for the treatment of rheumatic diseases, including systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis and primary Sjögren's syndrome. Although generally considered safe, adverse reactions have been reported with the use of HCQ and clinicians should carefully monitor patients with rheumatism when prescribing these drugs. The purpose of the present review is to strengthen the clinical use of HCQ for autoimmune diseases while highlighting the adverse effects that may occur during treatment.

Evaluation of cardiac function using echocardiography in childhood-onset systemic lupus erythematosus patients treated with hydroxychloroquine. Expert Rev Cardiovasc Ther 2024:1-5. [PMID: 39699079 DOI: 10.1080/14779072.2024.2445800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2024] [Revised: 12/05/2024] [Accepted: 12/18/2024] [Indexed: 12/20/2024]
Abstract
BACKGROUND This study aimed to evaluate the effects of hydroxychloroquine on cardiac functions and left ventricular mass in patients with childhood-onset systemic lupus erythematosus (cSLE). RESEARCH DESIGN AND METHODS Fifty patients with cSLE undergoing treatment with hydroxychloroquine underwent echocardiographic evaluation. All patients exhibited negative disease activity markers and were clinically in remission. RESULTS The median duration of hydroxychloroquine exposure was 7.1 (5.2-9.5) years, with a median cumulative dose of 784.8 (509.5-3437.6) grams. No correlation was identified between the parameters of left ventricular ejection fraction, left ventricular mass index and geometry, and cumulative hydroxychloroquine dose (p = 0.245, p = 0.094, p = 0.146, respectively). Furthermore, no significant correlation was identified between the cumulative dose of hydroxychloroquine and diastolic cardiac parameters (all p > 0.05). A comparison of the patients who received a cumulative dose of hydroxychloroquine below the median dose (the low-dose group) with those who received a higher dose (the high-dose group) revealed no significant differences in the echocardiographic parameters (all p > 0.05). CONCLUSIONS The findings of this study indicate that chronic hydroxychloroquine use in patients with cSLE does not result in adverse changes in left ventricular mass or impairment of cardiac functions. However, these patients should undergo regular evaluation to monitor for the potential development of cardiotoxicity.

Abstract
PURPOSE OF REVIEW This review focuses on the association between RA and heart failure, highlighting the role of inflammation and the prevalence of heart failure with preserved ejection fraction (HFpEF) in this population. RECENT FINDINGS The incidence of heart failure in RA patients is two to three times higher than in the general population, with inflammation playing a significant role independent of traditional cardiovascular risk factors. HFpEF accounts for about half of heart failure cases and is increasingly recognized in RA patients, although it remains underdiagnosed. Atypical presentations and non-specific symptoms further complicate diagnosis. Early control of inflammation has been shown to reduce the risk of heart failure development and progression, improving both morbidity and mortality outcomes. Rheumatoid arthritis (RA) is a systemic inflammatory disease affecting approximately 1% of the population, with cardiovascular disease being the leading cause of premature death in these patients.

The effect of post-oral bitter compound interventions on the postprandial glycemia response: A systematic review and meta-analysis of randomised controlled trials. Clin Nutr 2024; 43:31-45. [PMID: 39317085 DOI: 10.1016/j.clnu.2024.09.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 09/05/2024] [Accepted: 09/11/2024] [Indexed: 09/26/2024]
Abstract
BACKGROUND & AIMS The post-oral sensing of bitter compounds by a family of bitter taste receptors (TAS2Rs) is suggested to regulate postprandial glycemia in humans. However, reports are inconsistent. This systematic review used meta-analysis to synthesise the impact of bitter compound interventions on the postprandial glycaemic response in humans. METHODS Electronic databases (Medline, PubMed, and Web of Science) were systematically searched from inception to April 2024 to identify randomised controlled trials reporting the effect of interventions utilising post-oral bitter compounds vs. placebo on postprandial plasma glucose levels at t = 2 h (2 h-PPG), and area under the curve (AUC) of glucose, insulin, and c-peptide. The random-effect and subgroup analysis were performed to calculate pooled weighted mean differences (WMD), overall and by predefined criteria. RESULTS Forty-six studies (within 34 articles) were identified; 29 and 17 studies described chronic and acute interventions, respectively. The chronic interventions reduced 2 h-PPG (n = 21, WMD = -0.35 mmol/L, 95%CIs = -0.58, -0.11) but not AUC for glucose or insulin. Subgroup analysis showed the former was particularly evident in individuals with impaired glycemia, interventions longer than three months, or quinine family administration. The acute interventions did not improve the postprandial glycemia response, but subgroup analysis revealed a decrease in AUC-glucose after quinine family administration (n = 4 WMD = -90.40 (nmol × time/L), 95%CIs = -132.70, -48.10). CONCLUSION Chronic bitter compound interventions, particularly those from the quinine family, may have therapeutic potential in those with glycemia dysregulation. Acute intervention of the quinine family may also improve postprandial glucose. Given the very low quality of the evidence, further investigations with more rigorous methods are still required.

Abstract
Even though the use of SARS-CoV-2 vaccines during the COVID-19 pandemic showed unprecedented success in a short time, it also exposed a flaw in the current vaccine design strategy to offer broad protection against emerging variants of concern. However, developing broad-spectrum vaccines is still a challenge for immunologists. The development of universal vaccines against emerging pathogens and their variants appears to be a practical solution to mitigate the economic and physical effects of the pandemic on society. Very few reports are available to explain the basic concept of universal vaccine design and development. This review provides an overview of the innate and adaptive immune responses generated against vaccination and essential insight into immune mechanisms helpful in designing universal vaccines targeting influenza viruses and coronaviruses. In addition, the characteristics, safety, and factors affecting the efficacy of universal vaccines have been discussed. Furthermore, several advancements in methods worthy of designing universal vaccines are described, including chimeric immunogens, heterologous prime-boost vaccines, reverse vaccinology, structure-based antigen design, pan-reactive antibody vaccines, conserved neutralizing epitope-based vaccines, mosaic nanoparticle-based vaccines, etc. In addition to the several advantages, significant potential constraints, such as defocusing the immune response and subdominance, are also discussed.

Abstract
Quinoline-related antimalarial drugs have been associated with cardiotoxicity risk, in particular QT prolongation and QRS complex widening. In collaboration with Medicines for Malaria Venture, we discovered novel plasmepsin X (PMX) inhibitors for malaria treatment. The first lead compounds tested in anesthetized guinea pigs (GPs) induced profound QRS widening, although exhibiting weak inhibition of NaV1.5-mediated currents in standard patch clamp assays. To understand the mechanism(s) underlying QRS widening to identify further compounds devoid of such liability, we established a set of in vitro models including CaV1.2, NaV1.5 rate-dependence, and NaV1.8 patch clamp assays, human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM), and Langendorff-perfused isolated GP hearts. Six compounds were tested in all models including anesthetized GP, and 8 additional compounds were tested in vitro only. All compounds tested in anesthetized GP and isolated hearts showed a similar cardiovascular profile, consisting of QRS widening, bradycardia, negative inotropy, hypotension, and for some, QT prolongation. However, a left shift of the concentration-response curves was noted from in vitro to in vivo GP data. When comparing in vitro models, there was a good consistency between decrease in sodium spike amplitude in hiPSC-CM and QRS widening in isolated hearts. Patch clamp assay results showed that the QRS widening observed with PMX inhibitors is likely multifactorial, primarily due to NaV1.8 and NaV1.5 rate-dependent sodium blockade and/or calcium channel-mediated mechanisms. In conclusion, early de-risking of QRS widening using a set of different in vitro assays allowed to identify novel PMX inhibitors with improved cardiac safety profile.

Abstract
PURPOSE OF REVIEW In this review, we aimed to summarize the different aspects of the field of cardio-rheumatology, the role of the cardio-rheumatologist, and future research in the field. RECENT FINDINGS Cardio-rheumatology is an emerging subspecialty within cardiology that focuses on addressing the intricate relationship between systemic inflammation and cardiovascular diseases. It involves understanding the cardiovascular impact of immune-mediated inflammatory diseases on the heart and vascular system. A cardio-rheumatologist's role is multifaceted. First, they should understand the cardiac manifestations of rheumatological diseases. They should also be knowledgeable about the different immunotherapies available and side effects. Additionally, they should know how to utilize imaging modalities, either for diagnosis, prognosis, or treatment monitoring. This field is constantly evolving with new research on both treatment and imaging of the effects of inflammation on the cardiovascular system.

Hydroxychloroquine-induced cardiomyopathy: role of cardiac magnetic resonance for the diagnosis and follow-up of a very rare entity-a case report. Eur Heart J Case Rep 2024; 8:ytae404.

Abstract
Background Hydroxychloroquine (HCQ) is a disease-modifying antirheumatic used in rheumatological diseases such as systemic lupus erythematosus. Long-term exposure to HCQ results in drug accumulation and predisposes to adverse effects. Case summary We present the case of a 45-year-old woman with long-term treatment with HCQ who presented to the Emergency Department with acute heart failure. Transthoracic echocardiogram, previously normal, showed severe biventricular hypertrophy and biventricular systolic dysfunction. Cardiac magnetic resonance (CMR) confirmed the previous findings and showed elevated native T1 and T2 values, elevated extracellular volume, and extensive mid-wall late gadolinium enhancement (LGE). Infiltrative cardiomyopathy was suspected, and endomyocardial biopsy performed. Light microscopy showed myocyte hypertrophy and vacuolar change and absence of lymphocytic inflammatory infiltrates. The diagnosis of HCQ-induced cardiomyopathy was established, and the drug was withdrawn. A CMR performed 1 year later showed normal systolic function of both ventricles and normalization of T2 values, reflecting resolution of myocardial oedema. However, severe hypertrophy, elevated native T1 values, and LGE persisted. Discussion Our case shows that although discontinuation of the drug stops the progression of the disease, established myocardial structural damage persists. Early diagnosis of this entity is therefore essential to improve prognosis.

Abstract
Antimalarials (AMs), particularly hydroxychloroquine (HCQ) and chloroquine (CQ), are the cornerstone of the treatment for both systemic lupus erythematosus (SLE) and cutaneous lupus erythematosus (CLE). HCQ and CQ are recommended as first-line oral agents in all CLE guidelines. Initially thought to have potential therapeutic effects against COVID-19, HCQ has drawn significant attention in recent years, highlighting concerns over its potential toxicity among patients and physicians. This review aims to consolidate current evidence on the efficacy of AMs in CLE. Our focus will be on optimizing therapeutic strategies, such as switching from HCQ to CQ, adding quinacrine to either HCQ or CQ, or adjusting HCQ dose based on blood concentration. Additionally, we will explore the potential for HCQ dose reduction or discontinuation in cases of CLE or SLE remission. Our review will focus on the existing evidence regarding adverse events linked to AM usage, with a specific emphasis on severe events and those of particular interest to dermatologists. Last, we will discuss the optimal HCQ dose and the balance between preventing CLE or SLE flares and minimizing toxicity.

Abstract
BACKGROUND COVID-19 is a new infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS CoV-2). Since the outbreak in December 2019, it has caused an unprecedented world pandemic, leading to a global human health crisis. Although SARS CoV-2 mainly affects the lungs, causing interstitial pneumonia and severe acute respiratory distress syndrome, a number of patients often have extensive clinical manifestations, such as gastrointestinal symptoms, cardiovascular damage and renal dysfunction. PURPOSE This review article discusses the pathogenic mechanisms of cardiovascular damage in COVID-19 patients and provides some useful suggestions for future clinical diagnosis, treatment and prevention. METHODS An English-language literature search was conducted in PubMed and Web of Science databases up to 12th April, 2024 for the terms "COVID-19", "SARS CoV-2", "cardiovascular damage", "myocardial injury", "myocarditis", "hypertension", "arrhythmia", "heart failure" and "coronary heart disease", especially update articles in 2023 and 2024. Salient medical literatures regarding the cardiovascular damage of COVID-19 were selected, extracted and synthesized. RESULTS The most common cardiovascular damage was myocarditis and pericarditis, hypertension, arrhythmia, myocardial injury and heart failure, coronary heart disease, stress cardiomyopathy, ischemic stroke, blood coagulation abnormalities, and dyslipidemia. Two important pathogenic mechanisms of the cardiovascular damage may be direct viral cytotoxicity as well as indirect hyperimmune responses of the body to SARS CoV-2 infection. CONCLUSIONS Cardiovascular damage in COVID-19 patients is common and portends a worse prognosis. Although the underlying pathophysiological mechanisms of cardiovascular damage related to COVID-19 are not completely clear, two important pathogenic mechanisms of cardiovascular damage may be the direct damage of the SARSCoV-2 infection and the indirect hyperimmune responses.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease that affects the living quality of patients, especially the elderly population. RA-related morbidity and mortality increase significantly with age, while current clinical drugs for RA are far from satisfactory and may have serious side effects. Therefore, the development of new drugs with higher biosafety and efficacy is demanding. Black phosphorus nanosheets (BPNSs) have been widely studied because of their excellent biocompatibility. Here, we focus on the inherent bioactivity of BPNSs, report the potential of BPNSs as a therapeutic drug for RA and elucidate the underlying therapeutic mechanism. We find that BPNSs inhibit autophagy at an early stage via the AMPK-mTOR pathway, switch the energy metabolic pathway to oxidative phosphorylation, increase intracellular ATP levels, suppress apoptosis, reduce inflammation and oxidative stress, and down-regulate senescence-associated secretory phenotype (SASP)-related genes in rheumatoid arthritis synovial fibroblasts (RA-SFs). Further, BPNSs induce the apoptosis of macrophages and promote their transition from the M1 to the M2 phenotype by regulating related cytokines. Significantly, the administration of BPNSs can alleviate key pathological features of RA in mice, revealing great therapeutic potential. This study provides a novel option for treating RA, with BPNSs emerging as a promising therapeutic candidate.

Abstract
The use of the antimalarial drug hydroxychloroquine is a standard treatment in patients with systemic lupus erythematosus. It helps reduce disease-associated damage, prevents disease flare, and improves overall survival. The mechanism of action of hydroxychloroquine includes interference with lysosomal degradation of cells leading to the accumulation of vacuoles. Retinopathy is a well-described adverse effect of hydroxychloroquine, thus requiring screening with an ophthalmologist after prolonged use. Although rarely reported, cardiac adverse effects of hydroxychloroquine can also occur. In this report, we present a case of a 23-year-old woman with systemic lupus erythematosus on hydroxychloroquine who presented with stroke possibly due to Libman-Sacks endocarditis and was found to have severe hypertrophic cardiomyopathy on transthoracic echocardiogram.

Abstract
INTRODUCTION Cardiovascular disease (CVD) is the leading cause of mortality in patients with rheumatoid arthritis (RA). Some studies have reported a decrease in CVD in patients with RA using hydroxychloroquine (HCQ). Most of these have had fewer participants and have analyzed only composite outcomes. We aimed to identify the association between the use of HCQ in patients with RA and the incidence of major adverse cardiac events (MACEs), cerebral infarction, and AMI. METHODS This was a retrospective observational study using the TriNetX Diamond Network. Propensity score matching (PSM) was used to equilibrate the cohorts. The dependent variables in our study were MACE, cerebral infarction, and AMI. RESULTS A total of 2,261,643 patients with RA were identified. Approximately 6% had been prescribed HCQ. Of those prescribed HCQ, 80% (112,743) were females, while of those not prescribed HCQ, 72.5% (1,536,937) were females. HCQ was associated with lower rates of MACE (HR 0.827, 95%CI 0.8,0.86), cerebral infarction (HR 0.824, 95% CI 0.78,0.87), and AMI (HR 0.9, 95% CI 0.85,0.96). These associations were not seen in patients taking biologics. HCQ was associated with lower MACE in all other subgroups. CONCLUSION In conclusion, HCQ was slightly beneficial in decreasing MACE and cerebral infarction in patients with RA. These associations were significantly lower in patients taking methotrexate or biologics. Although there was a significant decrease in the risk of AMI in all patients with RA, these results were not replicated in subgroup analyses, and there was an apparent increased risk of AMI with the use of HCQ in patients using biologics.

Abstract
Chloroquine (CQ) has a long clinical history as an anti-malarial agent and also being used for the treatment of other infections and autoimmune diseases. Recently, this lysosomotropic agent and its derivatives are also been tested as adjuncts alongside conventional anti-cancer treatments in combinatorial therapies. However, their reported cardiotoxicity tends to raise concern over their indiscriminate use. Even though the influence of CQ and its derivatives on cardiac mitochondria is extensively studied in disease models, their impact on cardiac mitochondrial respiration under physiological conditions remains inconclusive. In this study, we aimed to evaluate the impact of CQ on cardiac mitochondrial respiration using both in-vitro and in-vivo model systems. Using high-resolution respirometry in isolated cardiac mitochondria from male C57BL/6 mice treated with intraperitoneal injection of 10 mg/kg/day of CQ for 14 days, CQ was found to impair substrate-mediated mitochondrial respiration in cardiac tissue. In an in-vitro model of H9C2 cardiomyoblasts, incubation with 50 µM of CQ for 24 h disrupted mitochondrial membrane potential, produced mitochondrial fragmentation, decreased mitochondrial respiration and induced superoxide generation. Altogether, our study results indicate that CQ has a deleterious impact on cardiac mitochondrial bioenergetics which in turn suggests that CQ treatment could be an added burden, especially in patients affected with diseases with underlying cardiac complications. As CQ is an inhibitor of the lysosomal pathway, the observed effect could be an outcome of the accumulation of dysfunctional mitochondria due to autophagy inhibition.

Abstract
In Morocco, chloroquine/hydroxychloroquine + azithromycin have been used off-label for COVID-19 treatment. This study aimed to describe the distribution, nature and seriousness of the adverse drug reactions (ADRs) associated with the two drug combinations in COVID-19 in-patients. We conducted a prospective observational study based on intensive pharmacovigilance in national COVID-19 patients' management facilities from April 1 to June 12, 2020. Hospitalized patients treated with chloroquine/hydroxychloroquine + azithromycin and who experienced ADRs during their hospital stay were included in the study. The causality and seriousness of the ADRs were assessed using the World Health Organization-Uppsala Monitoring Centre method and the agreed criteria in the ICH guideline (E2A) respectively. A total of 237 (51.7%) and 221 (48.3%) COVID-19 in-patients treated respectively with chloroquine + azithromycin and hydroxychloroquine + azithromycin experienced 946 ADRs. Serious ADRs occurred in 54 patients (11.8%). Gastrointestinal system was most affected both in patients taking chloroquine + azithromycin (49.8%) or hydroxychloroquine + azithromycin (54.2%), followed by nervous system and psychiatric. Eye disorders were more frequent in patients receiving chloroquine + azithromycin (10.3%) than those receiving hydroxychloroquine + azithromycin (1.2%). Cardiac ADRs accounted for 6.4% and 5.1% respectively. Chloroquine + azithromycin caused more ADRs by patients than hydroxychloroquine + azithromycin (2.6 versus 1.5 ADRs/patient). Causality assessment was possible for 75.7% of the ADRs. Diabetes was identified as a risk factor for serious ADRs (ORa 3.56; IC: 95% 1.5-8.6). The off-label use of the two drug combinations in COVID-19 in-patients according to the national therapeutic protocol seems to be safe and tolerable. ADRs were mainly expected. However, precaution should be taken in using the drugs in diabetic patients to prevent the risk of serious ADRs.

Abstract
Hydroxychloroquine is one of the oldest disease-modifying anti-rheumatic drugs in clinical use. The drug interferes with lysosomal activity and antigen presentation, inhibits autophagy, and decreases transcription of pro-inflammatory cytokines. Owing to its immunomodulatory, anti-inflammatory, anti-thrombotic effect, hydroxychloroquine has been an integral part of therapy for systemic lupus erythematosus and lupus nephritis for several decades. The therapeutic versatility of hydroxychloroquine has led to repurposing it for other clinical conditions, with recent studies showing reduction in proteinuria in IgA nephropathy. Research is also underway to investigate the efficacy of hydroxychloroquine in primary membranous nephropathy, Alport's syndrome, systemic vasculitis, anti-GBM disease, acute kidney injury and for cardiovascular risk reduction in chronic kidney disease. Hydroxychloroquine is well-tolerated, inexpensive, and widely available and therefore, should its indications expand in the future, it would certainly be welcomed. However, clinicians should be aware of the risk of irreversible and progressive retinal toxicity and rarely, cardiomyopathy. Monitoring hydroxychloroquine levels in blood appears to be a promising tool to evaluate compliance, individualize the dose and reduce the risk of retinal toxicity, although this is not yet standard clinical practice. In this review, we discuss the existing knowledge regarding the mechanism of action of hydroxychloroquine, its utility in lupus nephritis and other kidney diseases, the main adverse effects and the evidence gaps that need to be addressed in future research.

Abstract
Rheumatoid arthritis (RA) is an autoimmune inflammatory disease, of which the leading cause of death is cardiovascular disease (CVD). The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c) in RA decrease especially under hyperinflammatory conditions. It is conflictive with the increased risk of CVD in RA, which is called "lipid paradox". The systemic inflammation may explain this apparent contradiction. The increased systemic proinflammatory cytokines in RA mainly include interleukin-6(IL-6)、interleukin-1(IL-1)and tumor necrosis factor alpha(TNF-α). The inflammation of RA cause changes in the subcomponents and structure of HDL particles, leading to a weakened anti-atherosclerosis function and promoting LDL oxidation and plaque formation. Dysfunctional HDL can further worsen the abnormalities of LDL metabolism, increasing the risk of cardiovascular disease. However, the specific mechanisms underlying lipid changes in RA and increased CVD risk remain unclear. Therefore, this article comprehensively integrates the latest existing literature to describe the unique lipid profile of RA, explore the mechanisms of lipid changes, and investigate the impact of lipid changes on cardiovascular disease.

[PMID: 37893596 PMCID: PMC10608066 DOI: 10.3390/medicina59101878] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 10/01/2023] [Accepted: 10/18/2023] [Indexed: 10/29/2023]
Abstract
Elderly-onset rheumatoid arthritis (EORA) is a distinct clinical entity defined as the onset of rheumatoid arthritis (RA) in individuals aged over 60 years. EORA presents unique clinical features, including a more equitable distribution of sexes, a potential predilection for male involvement, a higher incidence of acute onset characterized by constitutional symptoms, a propensity for systemic manifestations, elevated sedimentation rates at disease onset, a reduced occurrence of rheumatoid factor positivity, increased titers of anti-citrullinated protein antibodies, a preference for involvement of large joints, elevated disease activity, the presence of bone erosions, and heightened patient disability. RA is recognized to consist of three partially overlapping subsets. One subset mirrors the classical RA clinical presentation, while the remaining subsets exhibit either a polymyalgia rheumatica-like phenotype or present with remitting seronegative symmetrical synovitis accompanied by pitting edema syndrome. In the initial stages of EORA management, non-steroidal anti-inflammatory drugs (NSAIDs) are not typically the first-line treatment choice, because seniors are much more prone to develop side effects due to NSAIDs, and the use of NSAIDs is in reality contraindicated to the majority of seniors due to comorbidities. Disease-modifying antirheumatic drugs (DMARDs), frequently methotrexate, are introduced immediately after the diagnosis is made. In cases where elderly patients demonstrate resistance to conventional DMARD therapy, the introduction of biological or targeted synthetic DMARDs becomes a viable treatment option. EORA presents a unique clinical profile, necessitating tailored treatment strategies. Our study emphasizes the challenges of NSAID use in seniors, highlighting the imperative shift toward DMARDs such as methotrexate. Future research should explore personalized DMARD approaches based on disease activity, comorbidities, and safety considerations, aiming to optimize treatment outcomes and minimize glucocorticoid reliance, thereby enhancing the quality of care for EORA patients.

Abstract
Systemic lupus erythematosus (SLE) is known to have various cardiac manifestations, including arrhythmias and tachycardia. However, it is rare to encounter severe sinus tachycardia as a presenting feature in patients with SLE. Herein, we present a case of a 32-year-old Filipino female with a history of recurrent hospital admissions due to palpitations and uncontrolled tachycardia. Despite trying various symptomatic treatments, her symptoms remained persistent. Ultimately, the patient was diagnosed with SLE during her hospital stay. Eventually, her symptoms improved after initiating steroids. In conclusion, severe sinus tachycardia could be an unusual presentation of SLE that physicians should consider.

Song E. Effects of hydroxychloroquine on atrial electrophysiology in in silico wild-type and PITX2 +/- atrial cardiomyocytes. Herz 2023; 48:384-392. [PMID: 36732468 PMCID: PMC9894744 DOI: 10.1007/s00059-023-05162-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 12/07/2022] [Accepted: 12/30/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Hydroxychloroquine (HCQ) is commonly used in the treatment of autoimmune diseases and increases the risk of QT interval prolongation. However, it is unclear how HCQ affects atrial electrophysiology and the risk of atrial fibrillation (AF). METHODS We quantitatively examined the potential atrial arrhythmogenic effects of HCQ on AF using a computational model of human atrial cardiomyocytes. We measured atrial electrophysiological markers after systematically varying HCQ concentrations. RESULTS The HCQ concentrations were positively correlated with the action potential duration (APD), resting membrane potential, refractory period, APD alternans threshold, and calcium transient alternans threshold (p < 0.05). By contrast, HCQ concentrations were inversely correlated with the maximum upstroke velocity and calcium transient amplitude (p < 0.05). When the therapeutic concentration (Cmax) of HCQ was applied, HCQ increased APD90 by 1.4% in normal sinus rhythm, 1.8% in wild-type AF, and 2.6% in paired-like homeodomain transcription factor 2 (PITX2)+/- AF, but did not affect the alternans thresholds. The overall in silico results suggest no significant atrial arrhythmogenic effects of HCQ at Cmax, instead implying a potential antiarrhythmic role of low-dose HCQ in AF. However, at an HCQ concentration of fourfold Cmax, a rapid pacing rate of 4 Hz induced prominent APD alternans, particularly in the PITX2+/- AF model. CONCLUSION Our in silico analysis suggests a potential antiarrhythmic role of low-dose HCQ in AF. Concomitant PITX2 mutations and high-dose HCQ treatments may increase the risk of AF, and this potential genotype/dose-dependent arrhythmogenic effect of HCQ should be investigated further.

Abstract
Autophagy, a dynamic and complex process responsible for the clearance of damaged cellular components, plays a crucial role in maintaining myocardial homeostasis. In the context of heart failure, autophagy has been recognized as a response mechanism aimed at counteracting pathogenic processes and promoting cellular health. Its relevance has been underscored not only in various animal models, but also in the human heart. Extensive research efforts have been dedicated to understanding the significance of autophagy and unravelling its complex molecular mechanisms. This review aims to consolidate the current knowledge of the involvement of autophagy during the progression of heart failure. Specifically, we provide a comprehensive overview of published data on the impact of autophagy deregulation achieved by genetic modifications or by pharmacological interventions in ischemic and non-ischemic models of heart failure. Furthermore, we delve into the intricate molecular mechanisms through which autophagy regulates crucial cellular processes within the three predominant cell populations of the heart: cardiomyocytes, cardiac fibroblasts, and endothelial cells. Finally, we emphasize the need for future research to unravel the therapeutic potential associated with targeting autophagy in the management of heart failure.

Abstract
Background Evidence from observational epidemiological studies indicated that rheumatoid arthritis (RA) increased the risk of heart failure (HF). However, there is a possibility that the correlation is not explained as a causative role for RA in the pathogenesis of HF. A two-sample Mendelian randomization (MR) framework was designed to explore the potential etiological role of RA in HF to identify the target to improve the burden of HF disease. Methods To assess the causal association between RA and HF, we analyzed summary statistics from genome-wide association studies (GWASs) for individuals of European descent. Genetic instruments for RA were identified at a genome-wide significance threshold (p < 5 × 10-8). Corresponding data were obtained from a GWAS meta-analysis (95,524 cases and 1,270,968 controls) to identify genetic variants underlying HF. MR estimates were pooled using the inverse variance weighted method. Complementary analyses were conducted to assess the robustness of the results. Results There was no evidence of a causal association between genetically predicted RA and HF [odds ratio (OR), 1.00; 95% confidence interval (CI), 0.99-1.02; P = 0.60]. Various sensitivity analyses suggested no pleiotropy detected (all p > 0.05). Conclusion Our findings did not support the causal role of RA in the etiology of HF. As such, therapeutics targeted at the control of RA may have a lower likelihood of effectively controlling the occurrence of HF.

Abstract
Hydroxychloroquine (HCQ) was repurposed for COVID-19 treatment. Subtherapeutic HCQ lung levels and cardiac toxicity of oral HCQ were overcome by intratracheal (IT) administration of lower HCQ doses. The crosslinker-free supercritical fluid technology (SFT) produces aerogels and impregnates them with drugs in their amorphous form with efficient controlled release. Mechanistic physiologically based pharmacokinetic (PBPK) modeling can predict the lung's epithelial lining fluid (ELF) drug levels. This study aimed to develop a novel HCQ SFT formulation for IT administration to achieve maximal ELF levels and minimal cardiac toxicity. HCQ SFT formulation was prepared and evaluated for physicochemical, in vitro release, pharmacokinetics, and cardiac toxicity. Finally, the rat HCQ ELF concentrations were predicted using PBPK modeling. HCQ was amorphous after loading into the chitosan-alginate nanoporous microparticles (22.7±7.6 μm). The formulation showed a zero-order release, with only 40% released over 30 min compared to 94% for raw HCQ. The formulation had a tapped density of 0.28 g/cm3 and a loading efficiency of 35.3±1.3%. The IT administration of SFT HCQ at 1 mg/kg resulted in 23.7-fold higher bioavailability, fourfold longer MRT, and eightfold faster absorption but lower CK-MB and LDH levels than oral raw HCQ at 4 mg/kg. The PBPK model predicted 6 h of therapeutic ELF levels for IT SFT HCQ and a 100-fold higher ELF-to-heart concentration ratio than oral HCQ. Our findings support the feasibility of lung-targeted and more effective SFT HCQ IT administration for COVID-19 compared to oral HCQ with less cardiac toxicity. Graphical abstract.

Abstract
OBJECTIVE To determine whether hydroxychloroquine (HCQ) dose is associated with adverse cardiac outcomes in patients with systemic lupus erythematosus (SLE). METHODS Patients with SLE taking HCQ and with ≥1 echocardiogram followed at a tertiary care center in the Bronx, New York between 2005 and 2021 were included. The HCQ weight-based dose at the HCQ start date was the main exposure of interest. The outcome was incident all-cause heart failure with reduced ejection fraction (HFrEF), life-threatening arrhythmia, or cardiac death. We used Fine-Gray regression models with death as a competing event to study the association of HCQ dose with the outcome. Due to a significant interaction between smoking and HCQ exposure, models were stratified by smoking status. Propensity score analysis was performed as a secondary analysis. RESULTS Of 294 patients, 37 (13%) developed the outcome over a median follow-up time of 7.9 years (interquartile range [IQR] 4.2-12.3 years). In nonsmokers (n = 226), multivariable analysis adjusted for age, body mass index, hypertension, chronic kidney disease, diabetes mellitus, and thromboembolism showed that higher HCQ weight-based doses were not associated with an increased risk of the outcome (subdistribution hazard ratio [HR] 0.62 [IQR 0.41-0.92], P = 0.02). Similarly, higher baseline HCQ doses were not associated with a higher risk of the outcome among smokers (n = 68) (subdistribution HR 0.85 [IQR 0.53-1.34] per mg/kg, P = 0.48). Propensity score analysis showed comparable results. CONCLUSION Higher HCQ doses were not associated with an increased risk of HFrEF, life-threatening arrhythmia, or cardiac death among patients with SLE and may decrease the risk among nonsmokers.

Abstract
Hydroxychloroquine sulfate (HCQ) and chloroquine diphosphate (CQ) have been used at increased rates to treat COVID-19 but can constitute a potential environmental risk. The objective was to evaluate the toxicity of sublethal concentrations of HCQ and CQ in zebrafish embryos/larvae. The 50% lethal concentrations (LC50) of HCQ and CQ at 96 h post-fertilization (hpf) were calculated by testing various concentrations on 2,160 embryos. The LC50 obtained were 560 and 800 µM for HCQ and CQ, respectively. Next, the embryotoxicity assay was performed, where 1,200 embryos were subjected to sublethal concentrations of HCQ and CQ. The hatching and heart rates were recorded. After euthanasia, photomicrographs of all larvae were taken to measure the total length, pericardial and yolk sac areas. The embryos exposed to sublethal concentrations of HCQ and CQ showed delayed hatching at 72 hpf, as well as an increase in the heart rate, larger pericardial and yolk sac areas, and body malformations at 96 hpf. The findings show that HCQ and CQ are toxic to fish in the early development phases. Understanding the mechanisms of toxicity will help extrapolate the effects of 4-aminoquinoline derivatives when they reach the aquatic environment in the context of the COVID-19 pandemic.

Abstract
Introduction: Post-marketing identification and report of unknown adverse drug reactions (ADRs) are crucial for patient safety. However, complete information on unknown ADRs seldom is available at the time of spontaneous ADR reports and this can hamper their contribution to the pharmacovigilance system. Methods: In order to characterize the seriousness and outcome of unknown ADRs at the time of report and at follow-up, and analyze their contribution to generate pharmacovigilance regulatory actions, a retrospective observational study of those identified in the spontaneous ADR reports of patients assisted at a hospital (January, 2016-December, 2021) was carried out. Information on demographic, clinical and complementary tests was retrieved from patients' hospital medical records. To evaluate the contribution to pharmacovigilance system we reviewed the European Union SmPCs, the list of the pharmacovigilance signals discussed by the Pharmacovigilance Risk Assessment Committee, and its recommendations reports on safety signals. Results: A total of 15.2% of the spontaneous reported cases during the study contained at least one unknown drug-ADR pair. After exclusions, 295 unknown drug-ADR pairs were included, within them the most frequently affected organs or systems were: skin and subcutaneous tissue (34, 11.5%), hepatobiliary disorders (28, 9.5%), cardiac disorders (28, 9.5%) and central nervous system disorders (27, 9.2%). The most frequent ADRs were pemphigus (7, 2.4%), and cytolytic hepatitis, sudden death, cutaneous vasculitis and fetal growth restriction with 6 (2%) each. Vaccines such as covid-19 and pneumococcus (68, 21.3%), antineoplastics such as paclitaxel, trastuzumab and vincristine (39, 12.2%) and immunosuppressants such as methotrexate and tocilizumab (35, 11%) were the most frequent drug subgroups involved. Sudden death due to hydroxychloroquine alone or in combination (4, 1.4%) and hypertransaminasemia by vincristine (n = 3, 1%) were the most frequent unknown drug-ADR pairs. A total of 269 (91.2%) of them were serious. Complementary tests were performed in 82.7% of unknown-ADR pairs and helped to reinforce their association in 18.3% of them. A total of 18 (6.1%) unknown drug-ADR pairs were evaluated by the EMA, in 8 (2.7%) the information was added to the drug's SmPC and in 1 case the risk prevention material was updated. Conclusion: Identification and follow-up of unknown ADRs can be of great relevance for patient safety and for the enrichment of the pharmacovigilance system.

Abstract
Zinc ions can hinder the synthesis of proteins required for accomplishing several stages of the viral life cycle. The intracellular zinc concentration can be increased by using zinc ionophores which transport zinc ions into the cells and hinder viral replication. (Hydroxy)chloroquine is an example of a zinc ionophore, but both zinc and (hydroxy)chloroquine can be toxic to the host organism. The nanocarriers may serve as camouflage to evade the adverse effects of drugs, chemicals, and nanoparticles on the host. We formulated ZnO nanoparticles with flower-like morphology (ZnONFs). It was further decorated with chitosan along with hydroxychloroquine (as a zinc ionophore) (CHCZnO NPs). We have chosen the cationic polymer chitosan since it is biocompatible, biodegradable and binds easily with the cells, and enhances the transport of drugs across cell membranes. The formulation was investigated for size, shape, surface charge, and interaction of chemicals used. We evaluated the formulations for cytotoxicity, and biocompatibility in embryonated chicks and their efficacy against bovine coronavirus (BCoV) isolated from a buffalo calf, and pneumo-enteric coronaviruses isolated from a buffalo calf with promising results in comparison to ZnONFs/hydroxychloroquine alone. Furthermore, we elucidate the mechanism underlying the lysosomotropic effect of various formulations on Vero cells infected with the buffalo coronavirus.

Abstract
OBJECTIVE Hydroxychloroquine (HCQ) is one of the most used drugs in patients with systemic lupus erythematosus (SLE). In these patients, where heart involvement is common, cardiac HCQ toxicity may lead to fatal outcomes. The aim of this work is to study the influence of cumulative HCQ (cHCQ) in a selected group of patients with SLE and its association with electrocardiographic (EKG) abnormalities. METHODS Single-center retrospective, observational study in which data were collected from the medical records of consecutive patients with a diagnosis of SLE who started treatment with HCQ and who had a 12-lead EKG before starting treatment and during follow-up. EKG abnormalities were grouped as conduction or structural abnormalities. The association of cHCQ with the occurrence of EKG disturbances was analyzed together with other demographic and clinical variables through univariate and multivariate logistic regression models. RESULTS 105 patients were selected with median cHCQ of 913 g. The sample was classified into two groups, above or below 913 g. Significantly, more conduction disturbances were observed in the group above the median (OR: 2.89; 95%CI: 1.01-8.23). In the multivariate analysis, the OR per 100 g of cHCQ dose was 1.06 (95%CI: 0.99-1.14). Age was the only variable associated with conduction disturbances. There were no significant differences in the development of structural abnormalities and a tendency for more high-grade atrioventricular block was shown. CONCLUSION Our study suggests an association between the cHCQ and the development of EKG conduction disturbances that disappears after multivariate adjustment. No increased number of structural abnormalities was observed.

Abstract
PURPOSE Patients with systemic lupus erythematosus (SLE) are at risk of cardiac disease including antimalarial-induced cardiomyopathy (AMIC). The purpose of this study is to evaluate cardiac magnetic resonance imaging parametric mapping findings in SLE patients with AMIC and investigate the relationship of T1/T2 mapping to antimalarial (AM) treatment duration. MATERIALS AND METHODS All patients with SLE who had undergone cardiac magnetic resonance imaging with T1/T2 mapping for evaluation of suspected cardiac disease between 2018 and 2021 were evaluated and compared with healthy controls. To facilitate comparison between scanners, T1/T2 values were converted to a z -score using scanner-specific local reference values. Patients were classified into 3 groups: AMIC, myocarditis, and other (no AMIC or myocarditis). RESULTS Forty-five SLE patients (47±17 y, 80% female; 8 [18%] with AMIC and 7 [16%] with myocarditis) and 30 healthy controls (39±15 y, 60% female) were included. Patients with AMIC had higher T1 and T2 compared with controls ( z -score 1.1±1.3 vs. 0±0.6, P =0.01 and 1.7±1.1 vs. 0±1.0, P <0.01, respectively) and lower values compared with those with myocarditis (3.7±1.6, P <0.01 and 4.0±2.0, P <0.01, respectively). T1 correlated negatively with AM treatment duration in patients without AMIC or myocarditis ( r =-0.36, P =0.048) and positively in patients with AMIC ( r =0.92, P =0.001). AM treatment duration did not correlate significantly with T1 in patients with myocarditis or with T2 in any group. CONCLUSIONS The relationship between T1 and AM treatment duration differed between groups. Native T1 decreases with longer treatment in patients without AMIC or myocarditis, possibility due to glycosphingolipid accumulation. In patients with AMIC, increasing T1 with longer treatment could reflect fibrosis.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59050863. [PMID: 37241095 DOI: 10.3390/medicina59050863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/14/2023] [Accepted: 04/27/2023] [Indexed: 05/28/2023]
Abstract
Background and Objectives: Hydroxychloroquine (HCQ) combined with azithromycin (AZM) has been widely administered to patients with COVID-19 despite scientific controversies. In particular, the potential of prolong cardiac repolarization when using this combination has been discussed. Materials and Methods: We report a pragmatic and simple safety approach which we implemented among the first patients treated for COVID-19 in our center in early 2020. Treatment contraindications were the presence of severe structural or electrical heart disease, baseline corrected QT interval (QTc) > 500 ms, hypokalemia, or other drugs prolonging QTc that could not be interrupted. Electrocardiogram and QTc was evaluated at admission and re-evaluated after 48 h of the initial prescription. Results: Among the 424 consecutive adult patients (mean age 46.3 ± 16.1 years; 216 women), 21.5% patients were followed in conventional wards and 78.5% in a day-care unit. A total of 11 patients (2.6%) had contraindications to the HCQ-AZ combination. In the remaining 413 treated patients, there were no arrhythmic events in any patient during the 10-day treatment regimen. QTc was slightly but statistically significantly prolonged by 3.75 ± 25.4 ms after 2 days of treatment (p = 0.003). QTc prolongation was particularly observed in female outpatients <65 years old without cardiovascular disease. Ten patients (2.4%) developed QTc prolongation > 60 ms, and none had QTc > 500 ms. Conclusions: This report does not aim to contribute to knowledge of the efficacy of treating COVID-19 with HCQ-AZ. However, it shows that a simple initial assessment of patient medical history, electrocardiogram (ECG), and kalemia identifies contraindicated patients and enables the safe treatment of COVID-19 patients with HCQ-AZ. QT-prolonging anti-infective drugs can be used safely in acute life-threatening infections, provided that a strict protocol and close collaboration between infectious disease specialists and rhythmologists are applied.

Abstract
BACKGROUND Medical therapies can cause cardiotoxicity. Chloroquine (QC) and hydroxychloroquine (HQC) are drugs used in the treatment of malaria and skin and rheumatic disorders. These drugs were considered to help treatment of coronavirus disease (COVID-19) in 2019. Despite the low cost and availability of QC and HQC, reports indicate that this class of drugs can cause cardiotoxicity. The mechanism of this event is not well known, but evidence shows that QC and HQC can cause cardiotoxicity by affecting mitochondria and lysosomes. METHODS Therefore, our study was designed to investigate the effects of QC and HQC on heart mitochondria. In order to achieve this aim, mitochondrial function, reactive oxygen species (ROS) level, mitochondrial membrane disruption, and cytochrome c release in heart mitochondria were evaluated. Statistical significance was determined using the one-way and two-way analysis of variance (ANOVA) followed by post hoc Tukey to evaluate mitochondrial succinate dehydrogenase (SDH) activity and cytochrome c release, and Bonferroni test to evaluate the ROS level, mitochondrial membrane potential (MMP) collapse, and mitochondrial swelling. RESULTS Based on ANOVA analysis (one-way), the results of mitochondrial SDH activity showed that the IC50 concentration for CQ is 20 µM and for HCQ is 50 µM. Based on two-way ANOVA analysis, the highest effect of CQ and HCQ on the generation of ROS, collapse in the MMP, and mitochondrial swelling were observed at 40 µM and 100 µM concentrations, respectively (p < 0.05). Also, the highest effect of these two drugs has been observed in 60 min (p < 0.05). The statistical results showed that compared to CQ, HCQ is able to cause the release of cytochrome c from mitochondria in all applied concentrations (p < 0.05). CONCLUSIONS The results suggest that QC and HQC can cause cardiotoxicity which can lead to heart disorders through oxidative stress and disfunction of heart mitochondria.

Abstract
Hydroxychloroquine (HCQ), a congener of chloroquine, is widely used in prophylaxis and the treatment of malaria, and also as a cure for rheumatoid arthritis, systemic lupus erythematosus, and various other diseases. Physiologically based pharmacokinetic modeling (PBPK) has attracted great interest in the past few years in predicting drug pharmacokinetics (PK). This study focuses on predicting the PK of HCQ in the healthy population and extrapolating it to the diseased populations, i.e., liver cirrhosis and chronic kidney disease (CKD), utilizing a systematically built whole-body PBPK model. The time vs. concentration profiles and drug-related parameters were obtained from the literature after a laborious search and in turn were integrated into PK-Sim software for designing healthy intravenous, oral, and diseased models. The model's evaluation was performed using observed-to-predicted ratios (Robs/Rpre) and visual predictive checks within a 2-fold error range. The healthy model was then extrapolated to liver cirrhosis and CKD populations after incorporating various disease-specific pathophysiological changes. Box-whisker plots showed an increase in AUC0-t in liver cirrhosis, whereas a decrease in AUC0-t was seen in the CKD population. These model predictions may assist clinicians in adjusting the administered HCQ doses in patients with different degrees of hepatic and renal impairment.

Abstract
OBJECTIVE Hydroxychloroquine (HCQ) is used in the treatment of inflammatory rheumatic diseases and is considered a safe drug. The role of HCQ in the COVID-19 pandemic highlighted some deleterious cardiac effects of HCQ. We aim to evaluate the prevalence and development of cardiac-adverse events in HCQ-treated patients with inflammatory rheumatic diseases. METHODS We performed a cross-sectional study where patients aged ≥18 years with a diagnosis of inflammatory rheumatic disease currently exposed or not to hydroxychloroquine underwent electrocardiogram (ECG) and echocardiogram. Comparisons between groups were evaluated using chi-square, t test, and Mann-Whitney U test. Logistic regression was performed to determine predictors of changes in ECG and echocardiography. RESULTS Eighty patients were included, 75 (93.8%) female, aged 52 ± 13 years. ECG changes were seen in higher proportion in patients with hypertension (40.6% vs 12.5%, p = .004) and higher median potassium levels-4.5 (4.1-4.8) versus 4.2 (4.0-4.4), p = .023. Echocardiography changes were seen in older patients (59 ± 11 vs 50 ± 13 years, p = .003) and in patients with higher cumulative dose-1752 (785-2190) versus 438 (328-1022) g, p = 0.008 - and time of exposure to HCQ - 12 (6-15) versus 4 (2-9) years, p = 0.028. HCQ cumulative dose (OR 1.001, CI95% 1.000-1.002, p = .033) and exposure time (OR 1.136, CI95% 1.000-1.289, p = .049) were predictors of echocardiography changes, but when adjusted for age, neither HCQ cumulative dose nor exposure time were predictors of echocardiography changes. CONCLUSION No association was found between changes in ECG and echocardiogram in patients under HCQ, which remains a safe drug in patients with inflammatory rheumatic diseases.

Abstract
Hydroxychloroquine (HCQ) and its close relative chloroquine (CQ) were initially used as antimalarial agents but are now widely prescribed in rheumatology, dermatology and immunology for the management of autoimmune diseases. HCQ is considered to have a better long-term safety profile than CQ and is therefore more commonly used. HCQ has a key role in the treatment of connective tissue diseases including systemic lupus erythematosus (SLE), where it provides beneficial immunomodulation without clinically significant immunosuppression. HCQ can also assist in managing inflammatory arthritis, including rheumatoid arthritis (RA). Debate around toxicity of HCQ in COVID-19 has challenged those who regularly prescribe HCQ to discuss its potential toxicities. Accordingly, we have reviewed the adverse effect profile of HCQ to provide guidance about this therapeutic agent in clinical practice.

Abstract
Systemic autoimmune rheumatic diseases (SARDs) are defined by the potential to affect multiple organ systems, and cardiac involvement is a prevalent but often overlooked sequela. Myocardial involvement in SARDs is medicated by macrovascular disease, microvascular dysfunction, and myocarditis. Systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, eosinophilic granulomatosis with polyangiitis, and sarcoidosis are associated with the greatest risk of myocardial damage and heart failure, though myocardial involvement is also seen in other SARDs or their treatments. Management of myocardial involvement should be disease-specific. Further research is required to elucidate targetable mechanisms of myocardial involvement in SARDs.

Abstract
The global pandemic of COVID-19 had a consequential impact on our lives. (Hydroxy)chloroquine, a well-known drug for treatment or prevention against malaria and chronic inflammatory conditions, was also used for COVID patients with reported potential efficacy. Although it was well tolerated, however in some cases, it produced severe side effects, including grave cardiac issues. The variable reports on the administration of (hydroxy)chloroquine in COVID19 patients led to chaos. This drug is a well-known zinc ionophore, besides possessing antiviral effects. Zinc ionophores augment the intracellular Zn2+ concentration by facilitating the zinc ions into the cells and subsequently impair virus replication. Zinc oxide nanoparticles (ZnO NPs) have been reported to possess antiviral activity. However, the adverse effects of both components are also reported. We discussed in depth their possible mechanism as antiviral and smart delivery perspectives through pH-sensitive polymers/ micelles and ZnO NPs.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that increases the risk of cardiovascular disease, but the causal relationship has remained unknown in the East Asian population. We aim to determine the causal relationship between SLE and congestive heart failure (CHF) in the East Asian population. METHODS We conducted a two-sample Mendelian randomization MR study to examine the potential causal association of SLE with CHF, using the East Asian genome-wide association study datasets for SLE (4222 cases, 8431 controls) and CHF (9413 cases, 203,040 controls). RESULTS The MR analysis showed that genetic susceptibility to SLE was associated with the increased risk of CHF (odds ratio [OR] 1.032, 95% confidence interval [CI] 1.004-1.061, p = .023). After excluding the human leukocyte antigen (HLA) regions, SLE was also associated with a higher risk of CHF (OR 1.034, 95% CI 1.007-1.062, p = .015). The multiple MR sensitivity analyses confirmed that this potential causal association was unlikely to be biased by horizontal pleiotropy. CONCLUSIONS The findings of this MR study suggest that SLE potentially increases the risk of CHF in the East Asian population. Genetic predisposition to SLE may play a significant role in developing CHF in the East Asian population.

Abstract
Background The global community has been affected by the coronavirus disease 2019 (COVID-19), which emerged in December 2019. Since then, many studies have been conducted on cardiovascular diseases (CVDs) and COVID-19. The aim of this study was to perform a bibliometric and visual analysis of the published relationship between CVDs and COVID-19. Methods 1,890 publications were retrieved from the Web of Science Core Collection database on January 5, 2022. Microsoft Office Excel and CiteSpace were then used to carry out scientometric analysis on the relevant literature according to seven aspects: document type, countries/regions, institutions, authors, journals, references, and keywords. Results The research on CVDs and COVID-19 is currently in a period of rapid development, with China, USA, England, and Italy leading the field. There is active cooperation between most countries and institutions. Harvard Medical School stands out among the many institutions not only for the largest number of publications, but also for their high quality. Banerjee A, Solomon SD and Narula J are three representative authors in this field. Frontiers in Cardiovascular Medicine was the journal with the highest number of published studies, and The Lancet was the most cited journal. Two documents with a high degree of significance in this field were identified. Popular research topics in this field are specific diseases, such as acute coronary syndrome and heart failure; pathogenesis related to ACE2, insulin resistance and pericyte; the specific therapeutic drug chloroquine; and clinical characteristics, physical activity, and mental health. ACE2 and NF-κB will be the focus of future research. Conclusions This study provides useful information for the research of CVDs and COVID-19, including potential collaborators, popular research topics, and a reference for more extensive and in-depth research in the future.

Abstract
AbstractWhile health care-associated financial burdens among uninsured individuals are well described, few studies have systematically characterized the array of financial and logistical complications faced by insured individuals with low household incomes. In this mixed methods paper, we conducted 6 focus groups with a total of 55 residents and analyzed programmatic administrative records to characterize the specific financial and logistic barriers faced by residents living in public housing in East and Central Harlem, New York City (NYC). Participants included individuals who enrolled in a municipal community health worker (CHW) program designed to close equity gaps in health and social outcomes. Dedicated health advocates (HAs) were explicitly paired with CHWs to provide health insurance and health care navigational assistance. We describe the needs of 150 residents with reported financial barriers to care, as well as the navigational and advocacy strategies taken by HAs to address them. Finally, we outline state-level policy recommendations to help ameliorate the problems experienced by participants. The model of paired CHW–HAs may be helpful in addressing financial barriers for insured populations with low household income and reducing health disparities in other communities.

Abstract
Malaria remains the leading cause of parasitic death in the world. Artemisinin resistance is an emerging threat indicating an imminent need for novel combination therapy. Given the key role of mass drug administration, it is pivotal that the safety of anti-malarial drugs is investigated thoroughly prior to widespread use. Cardiotoxicity, most prominently arrhythmic risk, has been a concern for anti-malarial drugs. We clarify the likely underlying mechanisms by which anti-malarial drugs predispose to arrhythmias. These relate to disruption of (1) action potential upstroke due to effects on the sodium currents, (2) action potential repolarisation due to effects on the potassium currents, (3) cellular calcium homeostasis, (4) mitochondrial function and reactive oxygen species production and (5) cardiac fibrosis. Together, these alterations promote arrhythmic triggers and substrates. Understanding these mechanisms is essential to assess the safety of these drugs, stratify patients based on arrhythmic risk and guide future anti-malarial drug development.

Abstract
PURPOSE 2019 Coronavirus disease (COVID-19) has caused millions of confirmed cases and deaths worldwide. TMPRSS2-mediated hydrolysis and maturation of spike protein is essential for SARS-CoV-2 infection in vivo. The latest research found that a TMPRSS2 inhibitor called N-0385 could effectively prevent the infection of the SARS-CoV-2 and its variants. However, it is not clear about the mechanism of N-0385 treatment COVID-19. Therefore, this study used computer simulations to investigate the mechanism of N-0385 treatment COVID-19 by impeding SARS-CoV-2 infection. METHODS The GeneCards database was used to search disease gene targets, core targets were analyzed by PPI, GO and KEGG. Molecular docking and molecular dynamics were used to validate and analyze the binding stability of small molecule N-0385 to target proteins. The supercomputer platform was used to simulate and analyze the number of hydrogen bonds, binding free energy, stability of protein targets at the residue level, radius of gyration and solvent accessible surface area. RESULTS There were 4,600 COVID-19 gene targets from GeneCards database. PPI, GO and KEGG analysis indicated that signaling pathways of immune response and inflammation played crucial roles in COVID-19. Molecular docking showed that N-0385 could block SARS-CoV-2 infection and treat COVID-19 by acting on ACE2, TMPRSS2 and NLRP3. Molecular dynamics was used to demonstrate that the small molecule N-0385 could form very stable bindings with TMPRSS2 and TLR7. CONCLUSION The mechanism of N-0385 treatment COVID-19 was investigated by molecular docking and molecular dynamics simulation. We speculated that N-0385 may not only inhibit SARS-CoV-2 invasion directly by acting on TMPRSS2, ACE2 and DPP4, but also inhibit the immune recognition process and inflammatory response by regulating TLR7, NLRP3 and IL-10 to prevent SARS-CoV-2 invasion. Therefore, these results suggested that N-0385 may act through multiple targets to reduce SARS-CoV-2 infection and damage caused by inflammatory responses.

Abstract
Purpose of Review The coronavirus disease 2019 (COVID-19) pandemic has popularized the usage of hydroxychloroquine and chloroquine (HCQ/CQ) as treatments for COVID-19. Previously used as anti-malarial and now commonly used in rheumatologic conditions, preliminary in vitro studies have demonstrated these medications also have anti-viral properties. Retinopathy and neuromyopathy are well recognized complications of using these treatments; however, cardiotoxicity is under-recognized. This review will discuss the implications and cardiotoxicity of HCQ/CQ, their mechanisms of action, and their utility in COVID-19. Recent Findings Early clinical trials demonstrated a modest benefit of HCQ in COVID-19, causing a push for the usage of it. However, further large multi-center randomized control centers, demonstrated no benefit, and even a trend towards worse outcomes. The predominant cardiac complication observed with HCQ in COVID-19 was cardiac arrhythmias and prolonging of the QT interval. However, with chronic usage of HCQ/CQ, the development of heart failure (HF) and cardiomyopathy (CM) can occur. Summary Although, most adverse cardiac events related to HCQ/CQ usage in COVID-19 were secondary to conduction disorders given the short duration of treatment, HCQ/CQ can cause CM and HF, with chronic usage. Given the insufficient evidence, HCQ/CQ usage in COVID-19 is not routinely recommended, especially with novel therapies now being developed and used. Additionally, usage of HCQ/CQ should prompt initial cardiac evaluation with ECG, and yearly monitoring, with consideration for advanced imaging if clinically warranted. The diagnosis of HCQ/CQ cardiomyopathy is important, as prompt cessation can allow for recovery when these changes are still reversible.

Abstract
Background Mental health disorders are among the most significant sequelae of the COVID-19 pandemic. Therefore, the aim of this study is to investigate the mental health status and associated risk factors of Moroccan COVID-19 survivors 3 months after hospital discharge. Methods A case-control study was conducted from September 2021 to February 2022 on 824 participants. 213 were COVID-19 survivors and 611 were control group. Data were collected ether through an online anonymous survey. Anxiety and depression disorders were assessed using Hospital Anxiety and Depression Scale (HADS). Results The average age of all participants was 55.17 ± 16.44. Our findings highlighted higher prevalence of mental health disorders including anxiety and depression in COVID-19 survivors at 3 months after hospital discharge (HADS-A = 12.84; HADS-D = 10.91) compared to control group (HADS-A = 9.90; HADS-D = 8.27) (p < 0.001). Older patients, suffering from type 2 diabetes and kidney diseases, admitted to ICU, who stayed a long duration in the hospital, who had severe and longer duration of symptoms and who used Chloroquine, had higher levels of anxiety and depression after discharge. Conclusions The present investigation highlights the need to develop a post-COVID-19 rehabilitation programs that can better manage the post COVID-19 impact and restore a good mental health for COVID-19 survivors. Also, to create preventative strategies to limit mental health disorders in COVID-19 survivors.
