Abstract
Obesity, diabetes, and other metabolic disorders place a huge burden on both the physical health and financial well-being of the community. While the need for effective treatment of metabolic disorders remains urgent and the reality is that traditional drug development involves high costs and a very long time with many pre-clinical and clinical trials, the need for drug repurposing has emerged as a potential alternative. Scientific evidence has shown the anti-diabetic and anti-obesity effects of old drugs, which were initially utilized for the treatment of inflammation, depression, infections, and even cancers. The drug library used modern technological methods to conduct drug screening. Computational molecular docking, genome-wide association studies, or omics data mining are advantageous and unavoidable methods for drug repurposing. Drug repurposing offers a promising avenue for economic efficiency in healthcare, especially for less common metabolic diseases, despite the need for rigorous research and validation. In this chapter, we aim to explore the scientific, technological, and economic issues surrounding drug repurposing for metabolic disorders. We hope to shed light on the potential of this approach and the challenges that need to be addressed to make it a viable option in the treatment of metabolic disorders, especially in the future fight against metabolic disorders.

Effect of hydroxychloroquine on beta cell function, insulin resistance, and inflammatory markers in type 2 diabetes patients uncontrolled on glimepiride and metformin therapy. Int J Diabetes Dev Ctries 2023; 43:1-6. [PMID: 36777472 PMCID: PMC9899060 DOI: 10.1007/s13410-023-01173-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Accepted: 01/17/2023] [Indexed: 02/05/2023] Open
Abstract
Background Very few studies have assessed the impact of hydroxychloroquine (HCQ) on insulin resistance, beta cell function, and inflammatory markers in diabetics which takes paramount importance in understanding the mechanism of its anti-diabetic effect. Objective To assess the effect of hydroxychloroquine on beta cell function and insulin resistance and inflammatory markers in type 2 diabetes patients uncontrolled on glimepiride and metformin combination. Study design and method 30 T2DM patients were inadequately controlled on glimepiride and metformin combination with an HbA1c between 7.5 and 10% (both inclusive) and were given hydroxychloroquine 400 mg in addition to glimepiride and metformin during the 12-week study period. Beta cell function, insulin resistance, high-sensitivity C-reactive protein (hsCRP), adiponectin, interleukin-6 (IL6), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), and glycated hemoglobin (HbA1c) were assessed at baseline and at 12 weeks after addition of 400 mg hydroxychloroquine. Results With addition of HCQ, there was a significant improvement in both beta cell function and insulin resistance (p < 0.001). There was also significant improvement in FPG, PPG, and HbA1c along with significant improvement in IL6, hsCRP, and adiponectin levels post 12 weeks of adjunctive treatment with hydroxychloroquine. The changes in beta cell function and insulin resistance correlated significantly with the changes in IL6, hsCRP, and adiponectin levels. Conclusion Addition of hydroxychloroquine as an add-on drug in uncontrolled diabetes significantly improves the beta cell function and the insulin resistance, along with significant improvement in adiponectin, hsCRP levels, and IL6 levels.

Diabetes-Modifying Antirheumatic Drugs: The Roles of DMARDs as Glucose-Lowering Agents. Medicina (B Aires) 2022; 58:medicina58050571.

Abstract
Systemic inflammation represents a shared pathophysiological mechanism which underlies the frequent clinical associations among chronic inflammatory rheumatic diseases (CIRDs), insulin resistance, type 2 diabetes (T2D), and chronic diabetes complications, including cardiovascular disease. Therefore, targeted anti-inflammatory therapies are attractive and highly desirable interventions to concomitantly reduce rheumatic disease activity and to improve glucose control in patients with CIRDs and comorbid T2D. Therapeutic approaches targeting inflammation may also play a role in the prevention of prediabetes and diabetes in patients with CIRDs, particularly in those with traditional risk factors and/or on high-dose corticosteroid therapy. Recently, several studies have shown that different disease-modifying antirheumatic drugs (DMARDs) used for the treatment of CIRDs exert antihyperglycemic properties by virtue of their anti-inflammatory, insulin-sensitizing, and/or insulinotropic effects. In this view, DMARDs are promising drug candidates that may potentially reduce rheumatic disease activity, ameliorate glucose control, and at the same time, prevent the development of diabetes-associated cardiovascular complications and metabolic dysfunctions. In light of their substantial antidiabetic actions, some DMARDs (such as hydroxychloroquine and anakinra) could be alternatively termed “diabetes-modifying antirheumatic drugs”, since they may be repurposed for co-treatment of rheumatic diseases and comorbid T2D. However, there is a need for future randomized controlled trials to confirm the beneficial metabolic and cardiovascular effects as well as the safety profile of distinct DMARDs in the long term. This narrative review aims to discuss the current knowledge about the mechanisms behind the antihyperglycemic properties exerted by a variety of DMARDs (including synthetic and biologic DMARDs) and the potential use of these agents as antidiabetic medications in clinical settings.

Abstract
Aims: No Cochrane meta-analysis with grading of evidence is available on use of hydroxychloroquine (HCQ) in type-2 diabetes (T2DM). This meta-analysis evaluated the efficacy and safety of HCQ in T2DM. Methods: Electronic databases were searched using a Boolean search strategy: ((hydroxychloroquine) OR (chloroquine*)) AND ((diabetes) OR (“diabetes mellitus”) OR (glycemia) OR (glucose) OR (insulin)) for studies evaluating hydroxychloroquine for glycemic control in T2DM. The primary outcome was a change in glycated haemoglobin (HbA1c). The secondary outcomes were changes in other glycemic/lipid parameters and adverse effects. Results: Data from 11 randomized controlled trials (RCTs) (3 having placebo as controls [passive controls] and 8 having anti-diabetes medications as controls [active controls]) involving 2,723 patients having a median follow-up of 24 weeks were analyzed. About 54.54% of the RCTs were of poor quality as evaluated by the Jadad scale. The performance bias and detection bias were at high risk in 63.64% of the RCTs. The HbA1c reduction with HCQ was marginally better compared to the active (mean differences [MD]-0.17% [95%, CI:-0.30–-0.04;P=0.009;I2=89%; very low certainty of evidence, VLCE]), and passive (MD-1.35% [95%CI:-2.10–-0.59;P=0.005;I2=74%]) controls. A reduction in fasting glucose (MD-16.63mg/dL[95%, CI: -25.99 – -7.28mg/dL;P<0.001;I2=97%;VLCE]) and post-prandial glucose [MD -8.41mg/dL (95%CI: -14.71 – -2.12mg/dL;P=0.009;I2=87%;VLCE]), appeared better with HCQ compared to active controls. The total adverse events (risk ratio [RR]0.93 [95% CI:0.68–1.28]; P=0.65;I2=66%) were not different with HCQ compared to the controls. Conclusion: The routine use of HCQ in T2DM cannot be recommended based on the current evidence.

Relationship of Hydroxychloroquine and Ophthalmic Complications in Patients with Type 2 Diabetes in Taiwan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18158154. [PMID: 34360449 PMCID: PMC8345959 DOI: 10.3390/ijerph18158154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Revised: 07/27/2021] [Accepted: 07/28/2021] [Indexed: 11/16/2022]
Abstract
The purpose of this study is to evaluate the relationship between hydroxychloroquine (HCQ) and diabetic retinopathy (DR) via the national health insurance research database (NHIRD) of Taiwan. All patients with newly diagnosed type 2 diabetes (n = 47,353) in the NHIRD (2000–2012) were enrolled in the study. The case group consists of participants with diabetic ophthalmic complications; 1:1 matching by age (±1 year old), sex, and diagnosis year of diabetes was used to provide an index date for the control group that corresponded to the case group (n = 5550). Chi-square test for categorical variables and Student’s t-test for continuous variables were used. Conditional logistic regression was performed to estimate the adjusted odds ratio (aOR) of DR. The total number of HCQ user was 99 patients (1.8%) in the case group and 93 patients (1.7%) in the control group. Patients with hypertension (aOR = 1.21, 95% CI = 1.11–1.31) and hyperlipidemia (aOR = 1.65, 95% CI = 1.52–1.79) significantly increased the risk of diabetic ophthalmic complications (p < 0.001). Conversely, the use of HCQ and the presence of rheumatoid diseases did not show any significance in increased risk of DR. HCQ prescription can improve systemic glycemic profile, but it does not decrease the risk of diabetic ophthalmic complications.

Abstract
BACKGROUND It has been suggested that hydroxychloroquine may have positive effects on LDL-C, HDL-C, and triglyceride levels; however, the hypolipidemic activities of this drug are still uncertain. OBJECTIVE The aim of this meta-analysis of randomized controlled trials was to explore the effect of hydroxychloroquine on circulating lipid concentrations. METHOD Randomized controlled trials examining the impact of hydroxychloroquine on lipid parameters were searched in PubMed, Web of Science, Scopus, and Google Scholar databases. Meta-analysis was performed using a random-effects model and sensitivity analysis through the leave one-out method. RESULTS Meta-analysis showed that patients receiving hydroxychloroquine therapy significantly decreased total cholesterol (WMD: 0.18 mmol/L, 95% CI: -0.28, -0.08, I2 = 6%, p = 0.0004), LDL-C (WMD: -0.21 mmol/L, 95% CI: -0.36, -0.06, I2 = 75%, p = 0.006), triglycerides (WMD: -0.09 mmol/L, 95% CI: -0.15, -0.04, I2 = 22%, p = 0.001), and non-HDL-C (WMD: -0.28 mmol/L, 95% CI: -0.45, -0.12, I2 = 0%, p = 0.0009), and increased HDL-C concentrations (WMD: 0.03 mmol/L, 95% CI: 0.00, 0.06, I2 = 0%, p = 0.03). CONCLUSION Our results suggest that hydroxychloroquine improves lipid parameters by reducing total cholesterol, LDL-C, triglycerides, non-HDL-C, and increasing HDL-C levels.

PURPOSE The aim of this meta-analysis of randomized controlled trials was to evaluate the effect of hydroxychloroquine on glucose control. METHODS Randomized controlled trials examining the impact of hydroxychloroquine on glycemic markers were searched in PubMed, Web of Science, Scopus, and Google Scholar databases. Meta-analysis was performed using a random-effects model and sensitivity analysis through the leave-one-out method. RESULTS Meta-analysis revealed a significant reduction of fasting glucose (WMD: - 8.05 mg/dl; 95% CI: - 11.17, - 4.93; I2 = 75%; p ˂0.0001), 2-h postprandial glucose (WMD: - 15.52 mg/dl; 95% CI: - 20.61, - 10.42; I2 = 53%; p ˂0.00001), and glycated hemoglobin (HbA1c) values (WMD: - 0.19%, 95% CI: - 0.37, - 0.02; I2 = 94%; p = 0.03) after hydroxychloroquine treatment. Otherwise, meta-analysis showed no significant effect of hydroxychloroquine on insulin levels (WMD: 16.52 μUI/ml; 95% CI: - 16.35, 49.40; I2 = 90%; p = 0.32) and HOMA-β (WMD: - 14.62; 95% CI: - 45.84, 16.59; I2 = 0%; p = 0.36). CONCLUSION The present meta-analysis revealed that treatment with hydroxychloroquine improves glucose control through the reduction of fasting glucose, 2-h postprandial glucose, and HbA1c values. Given that the effect of hydroxychloroquine on beta-cell function is based only on two clinical trials, it is not possible to draw definitive conclusions.

Abstract
Chloroquine (CQ) and hydroxychloroquine (HCQ) are traditional anti-malarial drugs that have been repurposed for new therapeutic uses in many diseases due to their simple usage and cost-effectiveness. The pleiotropic effects of CQ and HCQ in regulating blood pressure, glucose homeostasis, lipid, and carbohydrate metabolism have been previously described in vivo and in humans, thus suggesting their role in metabolic syndrome (MetS) prevention. The anti-hyperglycaemic, anti-hyperlipidaemic, cardioprotective, anti-hypertensive, and anti-obesity effects of CQ and HCQ might be elicited through reduction of inflammatory response and oxidative stress, improvement of endothelial function, activation of insulin signalling pathway, inhibition of lipogenesis and autophagy, as well as regulation of adipokines and apoptosis. In conclusion, the current state of knowledge supported the repurposing of CQ and HCQ usage in the management of MetS.

Abstract
Repurposing of antirheumatic drugs has garnered global attention. The aim of this article is to overview available evidence on the use of widely used antirheumatic drugs hydroxychloroquine, methotrexate and colchicine for additional indications. Hydroxychloroquine has endothelial stabilizing and anti-thrombotic effects. Its use has been explored as an adjunctive therapy in refractory thrombosis in antiphospholipid syndrome. It may also prevent recurrent pregnancy losses in the absence of antiphospholipid antibodies. Hydroxychloroquine favourably modulates atherogenic lipid and glycaemic profiles. Methotrexate has been tried for modulation of cardiovascular events in non-rheumatic clinical conditions, although a large clinical trial failed to demonstrate a benefit. Colchicine has been shown to successfully reduce the risk of recurrent cardiovascular events in a large multicentric trial. Potential antifibrotic effects of colchicine require further exploration. Hydroxychloroquine, methotrexate and colchicine are also being tried at different stages of the ongoing Coronavirus Disease 19 (COVID-19) pandemic for prophylaxis and treatment. While the use of these agents is being diversified, their adverse effects should be timely diagnosed and prevented. Hydroxychloroquine can cause retinopathy and rarely cardiac and auditory toxicity, retinopathy being dose and time dependent. Methotrexate can cause transaminitis, cytopenias and renal failure, particularly in acute overdoses. Colchicine can rarely cause myopathies, cardiomyopathy, cytopenias and transaminitis. Strong evidence is warranted to keep balance between benefits of repurposing these old antirheumatic drugs and risk of their adverse effects.

Abstract
BACKGROUND Hypoglycemia is the limiting factor in the glycemic management of diabetes, which need to be addressed critically to avoid complications. Lockdown because of new coronavirus strain (COVID-19) pandemic has further complicated the issue of hypoglycemia due to limitations in access to food, outpatient clinics, pathological services and medicines. AIM To assess the factors associated with the risk of hypoglycemia during April-May 2020 lockdown in people with type 2 diabetes mellitus. METHODOLOGY We analyzed the data retrospectively from 146 patients of type 2 diabetes mellitus (T2DM) reporting to the emergency department (ED) during lockdown period with symptoms suggestive of hypoglycemia. RESULTS The majority of patients were male (90/146) with a mean age of 59.88 ± 10.09 years and a mean random blood glucose level of 57.67 ± 9.00 mg/dL. Two-third of patients (70.83%) had level 1 hypoglycemia, while level 2 hypoglycemia was reported in 29.16% of patients. A combination of Metformin and Sulfonylureas (SU) was most commonly associated with the risk of hypoglycemia (65.75%) followed by insulin (33.56%). Subjects who received insulin reported a lower blood glucose value (50.75 ± 8.20 mg/dL) as compared to those receiving a combination of metformin and SU (60.95 ± 7.10 mg/dl). 330.56% of patients who had received prophylaxis hydroxychloroquine (HCQ) 400 mg twice a day along with the routine anti-hyperglycemic agents without their dose adjustment reported hypoglycemia. Patients with hypertension, micro-vascular, macro-vascular complications, and coexistent with each other had a higher propensity to the risk of hypoglycemia (46.58%, 33.56%, 23.29%, and 32.88%) respectively. CONCLUSION The COVID-19 lockdown has shown to influence the risk of hypoglycemia in patients with T2DM, especially those receiving SU, insulin, HCQ especially in patients with associated co-morbidities. Patient education, support, and telemedicine plays a pivotal role to prevent hypoglycemia.

Abstract
The antimalarial drug hydroxychloroquine (HCQ) has long been used as a disease-modifying antirheumatic drug for the treatment of several inflammatory rheumatic diseases. Over the last three decades, various studies have shown that HCQ also plays a role in the regulation of glucose homeostasis. Although the mechanisms of action underlying the glucose-lowering properties of HCQ are still not entirely clear, evidence suggests that this drug may exert multifaceted effects on glucose regulation, including improvement of insulin sensitivity, increase of insulin secretion, reduction of hepatic insulin clearance, and reduction of systemic inflammation. Preliminary studies have shown the safety and efficacy of HCQ (at a dose ranging from 400 to 600 mg/day) in patients with type 2 diabetes over a short-term period. In 2014, HCQ has been approved in India as an add-on hypoglycemic agent for patients with uncontrolled type 2 diabetes. However, large randomized controlled trials are needed to establish the safety and efficacy profile of HCQ in patients with type 2 diabetes over a long-term period. With regard to the COVID-19 pandemic, several medications (including HCQ) have been used as off-label drugs because of the lack of proven effective therapies. However, emerging evidence shows limited benefit from HCQ use in COVID-19 in general. The aim of this manuscript is to comprehensively summarize the current knowledge on the antihyperglycemic properties of HCQ and to critically evaluate the potential risks and benefits related to HCQ use in patients with diabetes, even in light of the current pandemic scenario.

Abstract
Multiple viral pathogens can pose a significant health risk to individuals. As a recent example, the β-coronavirus family virion, SARS-CoV-2, has quickly evolved as a pandemic leading to coronavirus disease 2019 (COVID-19) and has been declared by the World Health Organization as a Public Health Emergency of International Concern. To date, no definitive treatment or vaccine application exists for COVID-19. Although new investigations seek to repurpose existing antiviral treatments for COVID-19, innovative treatment strategies not normally considered to have antiviral capabilities may be critical to address this global concern. One such avenue that may prove to be exceedingly fruitful and offer exciting potential as new antiviral therapy involves the mechanistic target of rapamycin (mTOR) and its associated pathways of mTOR Complex 1 (mTORC1), mTOR Complex 2 (mTORC2), and AMP activated protein kinase (AMPK). Recent work has shown that mTOR pathways in conjunction with AMPK may offer valuable targets to control cell injury, oxidative stress, mitochondrial dysfunction, and the onset of hyperinflammation, a significant disability associated with COVID-19. Furthermore, pathways that can activate mTOR may be necessary for anti-hepatitis C activity, reduction of influenza A virus replication, and vital for type-1 interferon responses with influenza vaccination. Yet, important considerations for the development of safe and effective antiviral therapy with mTOR pathways exist. Under some conditions, mTOR can act as a double edge sword and participate in virion replication and virion release from cells. Future work with mTOR as a potential antiviral target is highly warranted and with a greater understanding of this novel pathway, new treatments against several viral pathogens may successfully emerge.
