Hydroxychloroquine: Key therapeutic advances and emerging nanotechnological landscape for cancer mitigation. Chem Biol Interact 2023; 386:110750. [PMID: 37839513 DOI: 10.1016/j.cbi.2023.110750] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 09/12/2023] [Accepted: 10/05/2023] [Indexed: 10/17/2023]
Abstract
Hydroxychloroquine (HCQ) is a unique class of medications that has been widely utilized for the treatment of cancer. HCQ plays a dichotomous role by inhibiting autophagy induced by the tumor microenvironment (TME). Preclinical studies support the use of HCQ for anti-cancer therapy, especially in combination with conventional anti-cancer treatments since they sensitize tumor cells to drugs, potentiating the therapeutic activity. However, clinical evidence has suggested poor outcomes for HCQ due to various obstacles, including non-specific distribution, low aqueous solubility and low bioavailability at target sites, transport across tissue barriers, and retinal toxicity. These issues are addressable via the integration of HCQ with nanotechnology to produce HCQ-conjugated nanomedicines. This review aims to discuss the pharmacodynamic, pharmacokinetic and antitumor properties of HCQ. Furthermore, the antitumor performance of the nanoformulated HCQ is also reviewed thoroughly, aiming to serve as a guide for the HCQ-based enhanced treatment of cancers. The nanoencapsulation or nanoconjugation of HCQ with nanoassemblies appears to be a promising method for reducing the toxicity and improving the antitumor efficacy of HCQ.

Abstract
Chloroquine diphosphate (CQ), a weak base used to inhibit autophagic flux and treat malaria and rheumatoid diseases, has been shown, through unknown mechanisms, to improve glucose and lipid homeostasis in patients and rodents. We investigate herein the molecular mechanisms underlying these CQ beneficial metabolic actions in diet-induced obese mice. For this, C57BL6/J mice fed with either a chow or a high-fat diet (HFD) and uncoupling protein 1 (UCP-1) KO and adipocyte Atg7-deficient mice fed with a HFD were treated or not with CQ (60 mg/kg of body weight/day) during 8 weeks and evaluated for body weight, adiposity, glucose homeostasis and brown and white adipose tissues (BAT and WAT) UCP-1 content. CQ reduced body weight gain and adipose tissue and liver masses in mice fed with a HFD, without altering food intake, oxygen consumption, respiratory exchange ratio, spontaneous motor activity and feces caloric content. CQ attenuated the insulin intolerance, hyperglycemia, hyperinsulinemia, hypertriglyceridemia and hypercholesterolemia induced by HFD intake, such effects that were associated with increases in serum and liver fibroblast growth factor 21 (FGF-21) and BAT and WAT UCP-1 content. Interestingly, CQ beneficial metabolic actions of reducing body weight and adiposity and improving glucose homeostasis were preserved in HFD-fed UCP-1 KO and adipocyte Atg7 deficient mice. CQ reduces body weight gain and adiposity and improves glucose homeostasis in diet-induced obese mice through mechanisms that might involve FGF-21, but not UCP1-mediated nonshivering thermogenesis or inhibition of adipocyte autophagy.

Abstract
PURPOSE OF THE REVIEW Systemic lupus erythematosus (SLE) patients are at increased risk of cardiovascular disease (CVD) compared to the general population, despite most patients being young females, who are not classically considered to be at high risk for cardiovascular disease using traditional risk assessment tools. The purpose of this review is to discuss the pathophysiology of atherosclerosis in SLE and raise awareness of the relationship between SLE and CVD. RECENT FINDINGS The increased risk of CVD in SLE patients is multifactorial, due to proatherogenic lipid profiles, immune dysregulation and inflammation, side effects of lupus treatment, and microvascular dysfunction. Conventional CV risk models often underperform in the identification of SLE patients at high risk of atherosclerosis. The use of non-invasive imaging serves as a strategy to identify patients with evidence of subclinical CVD and in the evaluation of symptomatic patients. Identification of subclinical atherosclerosis allows for aggressive management of CV risk factors. SLE patients experience an increased risk of atherosclerotic CVD, which is not solely explained by traditional CV risk factors. It is imperative that clinicians are aware of this association to implement prompt detection and treatment of atherosclerotic CVD in SLE patients.

Abstract
Background and aims To evaluate the effect of hydroxychloroquine (HCQ) on serum and lipoprotein lipids and serum biomarkers of cholesterol synthesis and absorption in myocardial infarction patients with a high-dose statin. Methods Myocardial infarction patients (n = 59) with a constant statin dose were randomized to receive hydroxychloroquine 300 mg (n = 31) or placebo (n = 28) daily for six months and followed up for one year. Results Statin reduced total-c (-26 ± 22% in hydroxychloroquine and -28 ± 19% in placebo group, P = 0.931), LDL-c (-38 ± 26% vs. -44 ± 23%, respectively, P = 0.299), and cholesterol synthesis biomarkers zymostenol, desmosterol, and lathosterol ratios from baseline to one year (e.g., serum lathosterol ratio -17 ± 45% vs. -15 ± 41%, respectively, P < 0.001 for both, P = 0.623 between groups). Compensatorily, cholesterol absorption increased during the intervention (e.g., serum campesterol ratio 125 ± 90% vs. 113 ± 72%, respectively, P < 0.001 for both, P = 0.488 between groups). Hydroxychloroquine did not affect cholesterol concentrations or cholesterol absorption. It prevented the statin-induced increase in cholesterol precursor, desmosterol ratio, from six months to one year in the hydroxychloroquine group (P = 0.007 at one year compared to placebo). Conclusions Combined with a high-dose statin, hydroxychloroquine had no additional effect on serum cholesterol concentration or cholesterol absorption. However, the findings suggest that hydroxychloroquine interferes with lanosterol synthesis, and thereafter, it temporarily interferes with the cholesterol synthesis pathway, best seen in halting the increase of the desmosterol ratio.Trial Registration ClinicalTrials.gov Identifier: NCT02648464.

Abstract
Chloroquine (CQ) and Hydroxychloroquine (HCQ), initially utilized in the treatment of malaria, have now developed a long list of applications. Despite their clinical relevance, their mechanisms of action are not clearly defined. Major pathways by which these agents are proposed to function include alkalinization of lysosomes and endosomes, downregulation of C-X-C chemokine receptor type 4 (CXCR4) expression, high-mobility group box 1 protein (HMGB1) inhibition, alteration of intracellular calcium, and prevention of thrombus formation. However, there is conflicting data present in the literature. This is likely the result of the complex overlapping pathways between these mechanisms of action that have not previously been highlighted. In fact, prior research has focused on very specific portions of particular pathways without describing these in the context of the extensive CQ/HCQ literature. This review summarizes the detailed data regarding CQ/HCQ's mechanisms of action while also providing insight into the overarching themes. Furthermore, this review provides clinical context to the application of these diverse drugs including their role in malaria, autoimmune disorders, cardiovascular disease, thrombus formation, malignancies, and viral infections.

Abstract
Objective Hydroxychloroquine (HCQ) is widely used in patients with systemic lupus erythematosus (SLE), but its effects on the mortality have not reached a definite conclusion. In this systematic review and meta-analysis, we aimed to assess whether HCQ use could reduce the risk of mortality in SLE patients. Methods PubMed, Embase, Web of Science, and Cochrane database were searched from inception to April 17, 2022 without language restrictions to explore the relationship between HCQ use and SLE mortality. The relative risk (HR) was pooled using the STATA software. Results A total of 21 studies with a pooled patient population of 26,037 were included in the study, including 14 studies on the association between HCQ alone and mortality risk and seven studies on the association between HCQ/chloroquine (CQ) and mortality risk. The pooled findings suggested that HCQ significantly reduced the overall mortality risk of SLE (pooled HR 0.46, 95% CI 0.38–0.57, p < 0.001). In subgroup analysis of SLE complications, HCQ use also decreased the risk of death in SLE patients with renal (HR=0.43, 95% CI 0.26–0.70, p = 0.001) and cardiopulmonary involvement (HR=0.37, 95% CI= 0.25–0.54, p < 0.001). In addition, HCQ use was also protective against the risk of mortality in SLE patients in different regions, such as Asia (HR=0.46, 95% CI=0.33–0.64, p < 0.001), Europe (HR= 0.40, 95% CI = 0.22–0.71, p = 0.002), and America (HR=0.52, 95% CI= 0.42–0.64, p < 0.001). Conclusion Our data suggested that HCQ use was associated with a reduced risk of mortality in patients with SLE.

Abstract
INTRODUCTION The beneficial effect of hydroxychloroquine (HCQ) in decreasing LDL levels on Systemic Lupus Erythematosus (SLE) is well defined. The influence of this drug on HDL levels is still under debate and information about its effect on cholesterol reverse transport is lacking. OBJECTIVE To evaluate the effects of HCQ on HDL levels and the transfer of lipids to this lipoprotein in SLE. METHODS Nineteen SLE patients using only HCQ (SLE WITH HCQ), 19 SLE patients without any therapy (SLE WITHOUT THERAPY), and 19 healthy controls (CONTROL) were included. All three groups were premenopausal women age- and gender-matched. Serum lipids and apolipoproteins were determined by commercial kits. An in vitro transfer of four lipids (14C-Phospolipid, 3H-Cholesteryl ester, 3H-Triglyceride, and 14C-Unesterified cholesterol) from a radioactively labeled nanoemulsion donor to HDL was performed in all participants. RESULTS Groups had comparable mean age, weight, height, BMI(body mass index), and waist circumference (p > .05). Mean HDL levels were higher in SLE WITH HCQ group compared to SLE WITHOUT THERAPY(58.37 ± 14.04 vs 49.79 ± 8.0 mg/dL; p < .05) but lower than CONTROL (58.37 ± 14.04 vs 68.58 ± 9.99 mg/dL; p < .05). Total cholesterol (TC) and LDL levels were also significantly lower in SLE WITH HCQ compared SLE WITHOUT THERAPY(148.16 ± 16.43 vs 167.11 ± 30.18 mg/dL; p < .05, 75.05 ± 22.52 vs 96.05 ± 25.63 mg/dL; p < .05) and CONTROL (148.16 ± 16.43 vs 174.11 ± 23.70 mg/dL; p < .05, 75.05 ± 22.52 vs 88.53 ± 20.24 mg/dL; p < .05). The in vitro lipid transfer to HDL study revealed a significant difference among the three groups (p = .002) with a higher transfer of unesterified cholesterol(UC) in SLE WITH HCQ compared to SLE WITHOUT THERAPY(5.40 ± 1.05% vs. 4.44 ± 1.05%; p < .05). The latter was significantly decreased compared to CONTROL (5.40 ± 1.05% vs. 5.99 ± 1.71%; p < .05).The percentages of transfer of triacylglycerol (4.93 ± 0.69% vs. 4.50 ± 0.69% vs. 5.14 ± 1.01%; p = .054), esterified cholesterol (5.24 ± 0.70% vs. 4.96 ± 0.89% vs. 5.69 ± 1.27%; p = .079), and phospholipid (15.67 ± 1.03% vs. 15.34 ± 1.44% vs. 16.47 ± 1.89%; p = .066) were similar among groups. CONCLUSION The present study is the first to demonstrate that HCQ promoted a higher transfer of unesterified cholesterol which may account for the increased HDL levels in lupus patients under HCQ. This desirable effect may underlie the reported reduced atherosclerosis in SLE.

Abstract
Systemic lupus erythematosus (SLE) is a heterogeneous disease characterized by the production of abnormal autoantibodies and immune complexes that can affect the organ and organ systems, particularly the kidneys and the cardiovascular system. Emerging evidence suggests that dysregulated lipid metabolism, especially in key effector cells, such as T cells, B cells, and innate immune cells, exerts complex effects on the pathogenesis and progression of SLE. Beyond their important roles as membrane components and energy storage, different lipids can also modulate different cellular processes, such as proliferation, differentiation, and survival. In this review, we summarize altered lipid metabolism and the associated mechanisms involved in the pathogenesis and progression of SLE. Furthermore, we discuss the recent progress in the role of lipid metabolism as a potential therapeutic target in SLE.

Abstract
The antimalarial hydroxychloroquine (HCQ) has demonstrated several crucial properties for the treatment of systemic lupus erythematosus (SLE). Herein, we reviewed the main HCQ pharmacologic features, detailed its mechanism of action, and summarized the existing guidelines and recommendations for HCQ use in rheumatology with a systematic literature search for the randomized controlled trials focused on lupus. HCQ has been shown to decrease SLE activity, especially in mild and moderate disease, to prevent disease flare and to lower the long-term glucocorticoid need. The numerous benefits of HCQ are extended to pregnancy and breastfeeding period. Based on cohort studies, antithrombotic and metabolic HCQ’s effects were shown, including lipid-lowering properties, which might contribute to an improved cardiovascular risk. Moreover, early HCQ use in antinuclear antibodies positive individuals might delay the progression to SLE. Finally, HCQ has a significant favorable impact on long-term outcomes such as damage accrual and mortality in SLE. Based on these multiple benefits, HCQ is now the mainstay long-term treatment in SLE, recommended by current guidelines in all patients unless contraindications or side effects. The daily dose associated with the best compromise between efficacy and safety is matter of debate. The concern regarding retinal toxicity rather than proper efficacy data is the one that dictated the daily dosage of ⩽5 mg/kg/day actual body weight currently agreed upon.

Abstract
Coronavirus disease 2019 (COVID-19) is a viral infection affecting multiple organ systems of great significance for metabolic processes. Thus, there is increasing interest in metabolic and lipoprotein signatures of the disease, and early analyses have demonstrated a metabolic pattern typical for atherosclerotic and hepatic damage in COVID-19 patients. However, it remains unclear whether this is specific for COVID-19 and whether the observed signature is caused by the disease or rather represents an underlying risk factor. To answer this question, we have analyzed 482 serum samples using nuclear magnetic resonance metabolomics, including longitudinally collected samples from 12 COVID-19 and 20 cardiogenic shock intensive care patients, samples from 18 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody-positive individuals, and single time point samples from 58 healthy controls. COVID-19 patients showed a distinct metabolic serum profile, including changes typical for severe dyslipidemia and a deeply altered metabolic status compared with healthy controls. Specifically, very-low-density lipoprotein and intermediate-density lipoprotein particles and associated apolipoprotein B and intermediate-density lipoprotein cholesterol were significantly increased, whereas cholesterol and apolipoprotein A2 were decreased. Moreover, a similarly perturbed profile was apparent when compared with other patients with cardiogenic shock who are in the intensive care unit when looking at a 1-week time course, highlighting close links between COVID-19 and lipid metabolism. The metabolic profile of COVID-19 patients distinguishes those from healthy controls and also from patients with cardiogenic shock. In contrast, anti-SARS-CoV-2 antibody-positive individuals without acute COVID-19 did not show a significantly perturbed metabolic profile compared with age- and sex-matched healthy controls, but SARS-CoV-2 antibody-titers correlated significantly with metabolic parameters, including levels of glycine, ApoA2, and small-sized low- and high-density lipoprotein subfractions. Our data suggest that COVID-19 is associated with dyslipidemia, which is not observed in anti-SARS-CoV-2 antibody-positive individuals who have not developed severe courses of the disease. This suggests that lipoprotein profiles may represent a confounding risk factor for COVID-19 with potential for patient stratification.

Abstract
Hydroxychloroquine and chloroquine, also known as antimalarial drugs, are widely used in the treatment of rheumatic diseases and have recently become the focus of attention because of the ongoing COVID-19 pandemic. Rheumatologists have been using antimalarials to manage patients with chronic immune-mediated inflammatory rheumatic diseases for decades. It is an appropriate time to review their immunomodulatory and anti-inflammatory mechanisms impact on disease activity and survival of systemic lupus erythematosus patient, including antiplatelet effect, metabolic and lipid benefits. We also discuss possible adverse effects, adding a practical and comprehensive approach to monitoring rheumatic patients during treatment with these drugs.

Abstract
BACKGROUND Dyslipidemia is a common disorder in systemic lupus erythematosus (SLE) patients. It is still inconclusive whether antimalarial drugs could affect the serum lipids in SLE patients, therefore we conducted a systematic review and meta-analysis of available data to address this issue. METHODS We comprehensively searched the databases of PubMed, EMBASE and Cochrane Library from date of inception to Sep 2018 for both randomized controlled trials (RCTs) and observational studies. Review Manager 5.3 software was used for analysis. We performed meta-analysis using random-effects model and weighted the mean difference (WMD) and its 95% confidence interval (CI). The Q test was used to assess the presence of heterogeneity and the I index was used to quantify the extent of heterogeneity. RESULTS In total, 8 studies met our selection criteria including 2 RCTs, 2 cohort studies, and 4 case-control studies. There were 717 patients (336 patients in CQ (chloroquine) or HCQ (hydroxychloroquine) group, and 381 patients in control group (SLE patients without the therapy of AM)). Compared with the control group, TC, TG, LDL-C, VLDL-C were associated with a significant decrease, respectively (WMD = -21.40 mg/dL, 95% CI -27.62 to -15.18, P < .00001), (WMD = -29.07 mg/dL, 95% CI -45.28 to -12.86, P = .0004), (WMD = -16.25 mg/dL, 95% CI -28.82 to -3.68, P = .01), (WMD = -6.41 mg/dL, 95% CI -12.39 to 0.44, P = .04), however the change of HDL-C did not reach statistically significance (WMD = 4.42 mg/dL, 95% CI -1.21 to 10.06, P = .12). CONCLUSIONS CQ or HCQ can infect the serum lipids in SLE patients. However, these results should be interpreted with cautions since lacking sufficient RCTs.

Abstract
Objectives To evaluate the incidence and variability of traditional coronary artery disease (CAD) risk factors in a cohort of lupus patients and to investigate if prednisone use predicts an increase in the number of risk factors. Methods A total of 151 women, 37.8 ± 11.1 (mean ± SD) years old at baseline, were reevaluated after a median period of 39 (interquartile range 36.5–42.0) months. The cumulative incidence of traditional risk factors, the incidence rate (with 95% confidence interval) of hypertension, diabetes, dyslipidemia and hypertriglyceridemia, and the frequency of the risk factors’ disappearance were calculated. Metabolic syndrome (MetS) and Framingham risk score (FRS) were computed. Logistic regression was used to investigate if maximum or cumulative prednisone dose used during follow-up predicted an increase in the cardiometabolic risk factors’ number. Results The cumulative incidence of risk factors varied from 39.1% (abdominal obesity) to zero (smoking), and the incidence rate varied from 133.2 (87.8–178.6) per 1000 person-years (dyslipidemia) to 10.4 (1.3–19.5) per 1000 person-years (diabetes). The cumulative incidence for MetS was 18.8%, and 11.7% of 143 patients with low FRS at baseline (T1) were classified in the high-risk category at the end of the study (T2). Dyslipidemia was the most variable risk factor, with 43.5% disappearance at T2. The maximum prednisone dose used during follow-up was borderline ( p = 0.050) for prediction of an increase in the number of cardiometabolic risk factors in an adjusted model for antimalarial use, modified Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and age. Conclusion The authors described high incidence and variability of CAD risk factors in female lupus patients, with higher prednisone dose being borderline for an increase in the number of cardiometabolic risk factors.

Abstract
Cardiovascular (CV) morbidity and mortality are a challenge in management of patients with systemic lupus erythematosus (SLE). Higher risk of CV disease in SLE patients is mostly related to accelerated atherosclerosis. Nevertheless, high prevalence of traditional cardiovascular risk factors in SLE patients does not fully explain the increased CV risk. Despite the pathological bases of accelerated atherosclerosis are not fully understood, it is thought that this process is driven by the complex interplay between SLE and atherosclerosis pathogenesis. Hydroxychloroquine (HCQ) is a cornerstone in treatment of SLE patients and has been thought to exert a broad spectrum of beneficial effects on disease activity, prevention of damage accrual, and mortality. Furthermore, HCQ is thought to protect against accelerated atherosclerosis targeting toll-like receptor signaling, cytokine production, T-cell and monocyte activation, oxidative stress, and endothelial dysfunction. HCQ was also described to have beneficial effects on traditional CV risk factors, such as dyslipidemia and diabetes. In conclusion, despite lacking randomized controlled trials unambiguously proving the protection of HCQ against accelerated atherosclerosis and incidence of CV events in SLE patients, evidence analyzed in this review is in favor of its beneficial effect.

Abstract
AIMS Hydroxychloroquine (HCQ) has shown to have significant immunomodulatory effects in the treatment of systemic lupus erythematosus (SLE). Current studies show favorable effects of HCQ on traditional cardiac risk factors in patients with SLE. This review examined the effects of HCQ on serum low-density lipoprotein (LDL) level in patients with SLE. METHODS A systematic search of seven major literature search databases from their inception until 3 April, 2017 identified nine studies. Random-effects pooled mean difference with corresponding 95% confidence intervals (CI) were estimated. Heterogeneity was measured by I2 . Publication bias was assessed by visual inspection of funnel plots. Sensitivity analysis examined whether HCQ effect on serum total cholesterol level was similar to the main analysis. The Grading of Recommendations Assessment, Development, and Evaluation system was used to assess the overall quality of evidence. RESULTS Pooled study participants were 559 patients from eight observation studies (two before-after studies; six case-control studies) examining the effects of HCQ on serum LDL. Pooled study participants' characteristics were as follows: mean age 45.719, female 95.262%, and prednisone use 58.366%. HCQ reduced mean LDL levels by 24.397 mg/dL (95% CI 8.921-39.872; P = 0.002). The number of studies identifying statin use was too few to perform meta-regression analysis of statin use. Heterogeneity was extensive (I2 = 94.739%). Symmetrical funnel plot visualized no evidence of publication bias. CONCLUSION HCQ was associated with serum LDL level reduction by mean 24.397 mg/dL in patients with SLE. Future prospective studies are need to fully characterize the treatment effect.

Abstract
Hydroxychloroquine (HCQ), a commonly used antimalarial drug in rheumatic diseases, has shown favorable metabolic effects on both glucose control and lipid profiles. We describe a case of a young woman with type 1 diabetes whose glycemic control was optimized with the introduction of HCQ as a treatment for her Sjogren syndrome in addition to a subtle yet measurable improvement in her lipid profile. An increasing body of evidence supports the beneficial impacts of HCQ in various ancillary conditions, including diabetes mellitus and dyslipidemia. However, mechanisms of action responsible for these effects remain ill-defined and may include alterations in insulin metabolism and signaling through cellular receptors. These favorable metabolic effects of HCQ and further understanding of underlying mechanisms may provide an additional rational for its use in rheumatic diseases, conditions associated with an elevated cardiovascular risk.

Abstract
The efficacy of antimalarials, especially hydroxychloroquine (HCQ), in preventing systemic lupus erythematosus (SLE) flares is well demonstrated. However, many studies show that the percentage of SLE patients treated with HCQ remains low. By blocking the toll-like receptor 7 and 9 in plasmacytoid dendritic cells, HCQ inhibits interferon-alpha production which plays a crucial role in SLE pathogenesis. In addition to reducing damage accrual in SLE patients, HCQ appears to protect against the occurrence of diabetes, thrombotic events, and dyslipidemia. As a consequence, some studies have suggested that HCQ, which is inexpensive, has a protective effect on survival in SLE patients. Thanks to the pharmacokinetic properties of HCQ (long half-life) and to the availability of its blood assay, very low or undetectable blood HCQ concentrations are a valuable marker of non-adherence to treatment, thus adding a new benefit to HCQ prescriptions. The main side effect of HCQ is retinal toxicity. This complication is very rare, but may be potentially severe, thus requiring regular screening. Retinal toxicity remains the only absolute contra-indication of HCQ in adult SLE patients. Other contra-indications are few and rare. During pregnancy and breast-feeding, HCQ continuation is not only allowed but recommended. In conclusion, the risk/benefit ratio of HCQ is excellent. Many now believe that all SLE patients should be offered this treatment.

Abstract
Antimalarial drugs have been in common use in dermatology since the 1950s. Their mechanism of action is complex, and it is now known that they act through various pathways. We review the indications for antimalarials in dermatology, their adverse effects, and some less well-known effects, such as their antithrombotic and hypolipidemic action. The most recent recommendations concerning ophthalmological screening in patients on antimalarials are also reviewed.

Abstract
OBJECTIVE Many studies have highlighted the hypolipidemic action of hydroxychloroquine (HCQ). We investigated the effect of HCQ on the lipid profile of patients with Sjögren syndrome (SS). METHODS The present retrospective observational study included 71 female patients with SS treated with HCQ. The levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol, triglycerides (TG), and atherogenic index (TC/HDL) were measured at baseline, after 6 months, and 1, 3, and 5 years after initiation of HCQ treatment. Analysis to investigate changes over time was performed in the entire patient group and in the separate subgroups: those receiving (21 patients) and those not receiving (50 patients) hypolipidemic treatment. RESULTS For the entire group of patients a statistically significant decrease in TC was noted (levels before treatment 220 ± 41 mg/dl, and at 5 yrs 206 ± 32 mg/dl, p = 0.006). A statistically significant difference was observed in the levels of HDL (57 ± 14 mg/dl vs 67 ± 17 mg/dl, p < 0.001) and in atherogenic index (4.0 ± 1.3 vs 3.3 ± 0.9, p < 0.001). Patients not receiving a hypolipidemic agent during the same period demonstrated a decrease in TC (214 ± 40 mg/dl vs 208 ± 34 mg/dl, p = 0.049), an increase in HDL levels (55 ± 15 mg/dl vs 67 ± 18 mg/dl, p < 0.001), and a decrease in atherogenic index (4.0 ± 1.4 vs 3.3 ± 0.9, p < 0.001). In the subgroup of patients receiving hypolipidemic treatment, the respective changes in their lipid profile were not significant in the first years but became significant in the long term. CONCLUSION Use of HCQ in patients with SS was related to a statistically significant decrease in TC, an increase in HDL, and improvement in the atherogenic index.

Abstract
OBJECTIVE To assess whether hydroxychloroquine (HCQ) prevents early damage in patients with systemic lupus erythematosus (SLE). METHODS We updated an existing systematic review of literature on clinical effects of HCQ in patients with SLE. We conducted a nested case-control study embedded in an inception cohort of patients with SLE. Systemic Lupus International Collaborating Clinics Damage Index (SDI) at 3 years was considered as our primary outcome. Patients with SDI > 0 at 3 years were considered cases and patients with SDI = 0 were controls. Cases and controls were first compared by univariate analysis. Then conditional logistic regression models adjusting for potential confounders were done to study the effect of HCQ on damage accrual. RESULTS Included in the analysis were 481 patients who had 3 or more years of followup. Out of this cohort, we could match 151 cases with 151 controls. Univariate analysis identified age, the use of any immunosuppressive drugs, HCQ, and cumulative dose of steroids as significant covariates associated with damage accrual. In multivariate analysis, the use of HCQ remained significantly associated with less damage (OR 0.34, 95% CI 0.132-0.867), while age (OR 1.05, 95% CI 1.027-1.078) and a variable combining SLE activity and steroid dose (OR 1.73, 95% CI 1.306-2.295) were associated with damage at 3 years. CONCLUSION We demonstrated that HCQ use was associated with less damage at 3 years after diagnosis of SLE when attention was given and adjustment done for disease activity and steroid dose, duration of disease, and calendar year of diagnosis.

Multifaceted effects of hydroxychloroquine in human disease. Semin Arthritis Rheum 2013; 43:264-72.

Abstract
OBJECTIVES Hydroxychloroquine (HCQ) is a widely used medication for the treatment of rheumatoid arthritis and systemic lupus erythematosus. An increasing body of evidence supports actions of this drug that are not directly related to its immunosuppressive or anti-rheumatic properties. The objective of this systematic review is to characterize the spectrum of conditions that might be responsive to treatment with HCQ. METHODS PubMed was searched using the MeSH for HCQ with relevant subheadings and the limits of human topics and English language. Four-hundred and fifty-six abstracts from this search were examined individually to exclude those that were not focused on the objectives of this review. The resulting 76 articles were grouped according to topic areas and reviewed in detail. RESULTS HCQ has been reported to have therapeutic effects in a wide array of conditions, including diabetes mellitus, dyslipidemias, coagulopathies, infectious diseases and malignancies. Mechanisms of action responsible for these effects likely include altered signaling through cellular receptors, post-glycosylation modifications of infectious agents, changes in levels of inflammatory mediators and inhibition of autophagy. Many of the pathways are likely dependent on drug-induced changes in intra-endosomal acidity. CONCLUSIONS The use of, and interest in, HCQ has spread into many areas of medicine. Actions of this drug may be directly beneficial to patients with non-rheumatic conditions such as diabetes mellitus or viral infections. Further understanding of underlying mechanisms has potential to reveal modifiable pathogenic pathways that might elucidate approaches to the design of more effective therapeutics for many chronic diseases.

Abstract
The influence of antimalarials on lipids in systemic lupus erythematosus (SLE) has been identified in several studies but not in many prospective cohorts. The aim of this study was to longitudinally determine the effect of antimalarials on the lipoprotein profile in SLE. Patients and methods: Fasting total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL) and low-density lipoprotein cholesterol (LDL) plasma levels were determined at entry and after 3 months of hydroxychloroquine (HCQ) treatment in a longitudinal evaluation of 24 patients with SLE. Results: a significant decrease in TC (198 ± 33.7 vs. 183 ± 30.3 mg/dl, p = 0.023) and LDL levels (117 ± 31.3 vs. 101 ± 26.2 mg/dl, p = 0.023) were detected after the 3 months of HCQ therapy. The reduction of 7.6% in TC ( p = 0.055) and 13.7% in LDL levels ( p = 0.036) determined a significant decrease in the frequency of dyslipidemia (26% vs. 12.5%, p = 0.013) after HCQ therapy. Conclusion: This longitudinal study demonstrated the beneficial effect of antimalarials on lipids in SLE since this therapy induced a reduction of atherogenic lipoproteins.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that affects various organs. Lupus nephritis is one of the most common, and most important, serious manifestations of SLE. Antimalarial agents are part of the immunomodulatory regimen used to treat patients with SLE; however, their role in the treatment of patients with lupus nephritis in particular is less well recognized, especially by nephrologists. Not all antimalarial agents have been used in the treatment of lupus; this Review will focus on studies using chloroquine and hydroxychloroquine. In addition, this Review will briefly describe the history of antimalarial drug use in patients with SLE, the theorized mechanisms of action of the agents chloroquine and hydroxychloroquine, their efficacy in patients with SLE and those with lupus nephritis, their use in pregnancy, and potential adverse effects. The Review will also cover the latest recommendations regarding monitoring for hydroxychloroquine-associated or chloroquine-associated retinopathy. Overall, antimalarial drugs have numerous beneficial effects in patients with SLE and lupus nephritis, and have a good safety profile.

Abstract
INTRODUCTION Previous studies have shown that traditional risk factors such as hypercholesterolemia and hypertension account for only a small proportion of the dramatically increased risk of atherosclerotic coronary artery disease (CAD) in systemic lupus erythematosus (SLE). However, in these studies, exposure to risk factors was measured only at baseline. In this study, our objective was to compare measures of cumulative exposure with remote and recent values for each of total cholesterol (TC), systolic (SBP), and diastolic (DBP) blood pressure in terms of ability to quantify risk of atherosclerotic CAD in patients with SLE. METHODS Patients in the Toronto lupus cohort had TC and BP measured at each clinic visit and were followed up prospectively for the occurrence of CAD. For each patient, arithmetic mean, time-adjusted mean (AM) and area-under-the-curve (AUC) were calculated for serial TC, SBP, and DBP measurements. Proportional hazards regression models were used to compare these summary measures with recent and first-available ("remote") measurements in terms of ability to quantify risk of CAD events, defined as myocardial infarction, angina, or sudden cardiac death. RESULTS The 991 patients had a mean ± SD of 19 ± 19 TC measurements per patient. Over a follow-up of 6.7 ± 6.4 years, 86 CAD events occurred; although remote TC was not significantly predictive of CAD, mean and AM TC were more strongly predictive (hazard ratio (HR) 2.07; P = 0.003) than recent TC (HR 1.86, P = 0.001). AUC TC was not predictive of CAD. A similar pattern was seen for DBP and SBP. Older age, male sex, higher baseline and recent disease activity score, and corticosteroid use also increased CAD risk, whereas antimalarials were protective. CONCLUSIONS In contrast to the population-based Framingham model, first-available TC and BP are not predictive of CAD among patients with SLE, in whom measures reflecting cumulative exposure over time are better able to quantify CAD risk. This is an important consideration in future studies of dynamic risk factors for CAD in a chronic relapsing-remitting disease such as SLE. Our findings also underpin the importance of adequate control of SLE disease activity while minimizing corticosteroid use, and highlight the cardioprotective effect of antimalarials.

Abstract
Introduction Total cholesterol (TC) and blood pressure (BP) are likely to take a dynamic course over time in patients with systemic lupus erythematosus (SLE). This would have important implications in terms of using single-point-in-time measurements of these variables to assess coronary artery disease (CAD) risk. The objective of this study was to describe and quantify variability over time of TC and BP among patients with SLE and to determine their correlates. Methods Patients in the Toronto lupus cohort who had two or more serial measurements of TC and systolic and diastolic BP (SBP and DBP) were included in the analysis. Variability over time was described in terms of the proportion of patients whose TC and BP profile fluctuated between normal and elevated (TC > 5.2 mmol/L; SBP ≥ 140 mm Hg or DBP ≥ 90 mm Hg), and also in terms of within- and between-patient variance quantified by using analysis of variance modeling. Generalized estimating equations (GEEs) were used to determine independent correlates of each of TC, SBP, and DBP, treated as continuous outcome variables. Results In total, 1,260 patients, comprising 26,267 measurements of each of TC, SBP, and DBP, were included. Mean ± SD number of measurements per patient was 20.8 ± 20. Mean ± SD time interval between measurements was 5.4 ± 9.7 months. Mean ± SD time interval from the start to the end of the study was 9.3 ± 8.5 years. Over time, 64.7% of patients varied between having normal and elevated cholesterol levels, whereas the status of 46.4% of patients varied between normotensive and hypertensive. By using analysis of variance (ANOVA), the within-patient percentage of total variance for each of TC, SBP, and DBP was 48.2%, 51.2%, and 63.9%, respectively. By using GEE, independent correlates of TC and BP included age, disease activity, and corticosteroids; antimalarial use was negatively correlated with TC (all P values < 0.0001). Conclusions TC and BP vary markedly over time in patients with SLE. This variability is due not only to lipid-lowering and antihypertensive medications, but also to disease- and treatment-related factors such as disease activity, corticosteroids, and antimalarials. The dynamic nature of TC and BP in SLE makes a compelling case for deriving summary measures that better capture cumulative exposure to these risk factors.

Abstract
In contrast to many other medications, chloroquine and hydroxychloroquine are approved treatment options for systemic lupus erythematosus (SLE). Antimalarials reduce the frequency of disease flares and contribute to the maintenance of remission. Apart from its direct effects on SLE activity, antimalarials seem to protect against thrombotic events and have a beneficial effect on glucose and lipid profiles, which might help reduce the high cardiovascular risk of SLE. Hydroxychloroquine is the only treatment shown to be effective in reducing the risk of damage accrual in SLE patients. Finally, antimalarials are inexpensive, especially compared with more recent treatments, and are well tolerated in SLE. Despite all these benefits, still only about 40%-50% of SLE patients are treated with (hydroxy)chloroquine. Particularly in early disease phases, antimalarials should be considered for every lupus patient, assuming there are no contraindications.

Abstract
Systemic lupus erythematosus (SLE) is associated with an increase in the risk of premature cardiovascular complications caused by accelerated atherosclerosis, which significantly contributes to morbidity and mortality. Standard Framingham risk factors seem to be less important predictors of cardiovascular events than the presence of active SLE, and the immune dysregulation characteristic of lupus seems to play a dominant role in atherogenesis. Although both SLE-specific and nonspecific mechanisms have been proposed to play a prominent role in the induction of premature vascular damage in this disease, the exact etiology remains unclear. This review summarizes some of the proposed mechanisms that may promote accelerated vascular damage in lupus and explores potential targets for cardiovascular risk prevention in this patient population.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disease with variable clinical manifestations that is characterized by flares and periods of relative quiescence. The disease occurs approximately 10 times more frequently in women and is more prevalent among certain ethnic groups. The etiology is complex and dependent upon an interaction of genetic, hormonal, and environmental factors. Corticosteroids and immunosuppressive agents have transformed the outlook for patients with lupus. Unfortunately, the increased lifespan unmasked an accelerated process of atherosclerosis and cardiovascular disease. Early mortality is usually attributable to active lupus, but deaths late in the disease process are often secondary to thrombotic events. Advancements in the understanding of molecular and cellular mechanisms involved in the pathogenesis have resulted in development of novel therapies. Immunomodulatory drugs developed for other diseases are being investigated for use in specific manifestations of lupus. Individualization of treatment and lifelong monitoring are required in most patients.

Abstract
The aim of this study was to analyze the effect of exposure to antimalarial drugs at diagnosis of lupus nephritis on the outcome of the disease, especially renal failure, comorbid processes, and survival. We analyzed a cohort of 206 consecutive patients with biopsy-proven lupus nephritis. Renal biopsies were categorized according to the classification proposed by the ISN/RPS in 2003. Exposure to antimalarial drugs (chloroquine and hydroxychloroquine) was defined as the use of these drugs before the diagnosis of lupus nephritis independent of dose and duration. Fifty-six (27%) patients had received antimalarials before the diagnosis of lupus nephritis. During the follow-up, these patients had a lower frequency of creatinine values >4 mg/dL (2% vs 11%, P = 0.029) and end-stage renal failure (2% vs 11%, P = 0.044) in comparison with those never treated with antimalarials. Patients exposed to antimalarials also had a lower frequency of hypertension (32% vs 50%, P = 0.027), infections (11% vs 29%, P = 0.006), and thrombotic events (5% vs 17%, P = 0.039). Twenty patients (10%) died during the study period. Patients exposed to antimalarials had a lower mortality rate at the end of the follow-up (2% vs 13% for those not exposed to antimalarials, P = 0.029). Multivariate analysis identified thrombosis and infections as statistically significant independent variables. Kaplan-Meier plots showed a lower rate of end-stage renal failure (log rank = 0.04) in patients exposed to antimalarials. In conclusion, exposure to antimalarials before the diagnosis of lupus nephritis was negatively associated with the development of renal failure, hypertension, thrombosis and infection, and with a better survival rate at the end of the follow-up. This, together with other published data, suggests that antimalarials should be considered a mandatory therapeutic option in all patients diagnosed with systemic lupus erythematosus.
