pmid sentence
32150618 Hydroxychloroquine shares the same mechanism of action as chloroquine, but its more tolerable safety profile makes it the preferred drug to treat malaria and autoimmune conditions. […] We propose that the immunomodulatory effect of hydroxychloroquine also may be useful in controlling the cytokine storm that occurs late-phase in critically ill SARS-CoV-2 infected patients. […] Currently, there is no evidence to support the use of hydroxychloroquine in SARS-CoV-2 infection. […] The pharmacological activity of chloroquine and hydroxychloroquine was tested using SARS-CoV-2 infected Vero cells. […] Using the PBPK models, hydroxychloroquine concentrations in lung fluid were simulated under 5 different dosing regimens to explore the most effective regimen whilst considering the drug’s safety profile. […] Hydroxychloroquine (EC50=0.72 μM) was found to be more potent than chloroquine (EC50=5.47 μM) in vitro. […] Based on PBPK models results, a loading dose of 400 mg twice daily of hydroxychloroquine sulfate given orally, followed by a maintenance dose of 200 mg given twice daily for 4 days is recommended for SARS-CoV-2 infection, as it reached three times the potency of chloroquine phosphate when given 500 mg twice daily 5 days in advance. […] Hydroxychloroquine was found to be more potent than chloroquine to inhibit SARS-CoV-2 in vitro.
32171740 In the absence of a known efficient therapy and because of the situation of a public-health emergency, it made sense to investigate the possible effect of chloroquine/hydroxychloroquine against SARS-CoV-2 since this molecule was previously described as a potent inhibitor of most coronaviruses, including SARS-CoV-1.
32196083 We propose that hydroxychloroquine (HCQ), which exhibits an antiviral effect highly similar to that of CQ, could serve as a better therapeutic approach.
32205204 Chloroquine and hydroxychloroquine have been found to be efficient on SARS-CoV-2, and reported to be efficient in Chinese COV-19 patients. […] We evaluate the role of hydroxychloroquine on respiratory viral loads. […] French Confirmed COVID-19 patients were included in a single arm protocol from early March to March 16th, to receive 600mg of hydroxychloroquine daily and their viral load in nasopharyngeal swabs was tested daily in a hospital setting. […] Azithromycin added to hydroxychloroquine was significantly more efficient for virus elimination. […] Despite its small sample size our survey shows that hydroxychloroquine treatment is significantly associated with viral load reduction/disappearance in COVID-19 patients and its effect is reinforced by azithromycin.

[…] We did a multinational registry analysis of the use of hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19. […] Patients who received one of the treatments of interest within 48 h of diagnosis were included in one of four treatment groups (chloroquine alone, chloroquine with a macrolide, hydroxychloroquine alone, or hydroxychloroquine with a macrolide), and patients who received none of these treatments formed the control group. […] Of these, 14 888 patients were in the treatment groups (1868 received chloroquine, 3783 received chloroquine with a macrolide, 3016 received hydroxychloroquine, and 6221 received hydroxychloroquine with a macrolide) and 81 144 patients were in the control group. 10 698 (11·1%) patients died in hospital. […] After controlling for multiple confounding factors (age, sex, race or ethnicity, body-mass index, underlying cardiovascular disease and its risk factors, diabetes, underlying lung disease, smoking, immunosuppressed condition, and baseline disease severity), when compared with mortality in the control group (9·3%), hydroxychloroquine (18·0%; hazard ratio 1·335, 95% CI 1·223-1·457), hydroxychloroquine with a macrolide (23·8%; 1·447, 1·368-1·531), chloroquine (16·4%; 1·365, 1·218-1·531), and chloroquine with a macrolide (22·2%; 1·368, 1·273-1·469) were each independently associated with an increased risk of in-hospital mortality. […] Compared with the control group (0·3%), hydroxychloroquine (6·1%; 2·369, 1·935-2·900), hydroxychloroquine with a macrolide (8·1%; 5·106, 4·106-5·983), chloroquine (4·3%; 3·561, 2·760-4·596), and chloroquine with a macrolide (6·5%; 4·011, 3·344-4·812) were independently associated with an increased risk of de-novo ventricular arrhythmia during hospitalisation. […] We were unable to confirm a benefit of hydroxychloroquine or chloroquine, when used alone or with a macrolide, on in-hospital outcomes for COVID-19.
32450198 The chloroquine (CQ) and its analogue hydroxychloroquine (HCQ) have been used as frontline drugs for treatment and prophylaxis against all types of human malaria worldwide. […] Based on accumulating scientific reports, we have highlighted in this review, the different possible modes of action of chloroquine/hydroxychloroquine that could particularly justify its use against viral infections. […] Considering the global health crisis of the COVID-19 pandemic, the option of using the drugs and repurposing of old drugs in this instance, chloroquine and hydroxychloroquine, specifically, hydroxychloroquine in the treatment of SARS-CoV-2 could be the best choice.
32451259 Repositioning hydroxychloroquine (HQ) seems to be a promising option.

32458599 Currently, chloroquine phosphate and hydroxychloroquine sulfate, two chloroquine derivatives, are under clinical use.
32458969 Two candidate medications have been widely discussed: remdesivir, and hydroxychloroquine+azithromycin. […] Hydroxychloroquine+azithromycin has been widely misrepresented in both clinical reports and public media, and outpatient trials results are not expected until September. […] Evidence about use of hydroxychloroquine alone, or of hydroxychloroquine+azithromycin in inpatients, is irrelevant concerning efficacy of the pair in early high-risk outpatient disease. […] Hydroxychloroquine+azithromycin has been used as standard-of-care in more than 300,000 older adults with multicomorbidities, with estimated proportion diagnosed with cardiac arrhythmias attributable to the medications 47/100,000 users, of which estimated mortality is <20%, 9/100,000 users, compared to the 10,000 Americans now dying each week.

[…] However, hydroxychloroquine did not show significant inhibitory effects on anti-SARS-CoV-2-mediated cytotoxicity or on viral load at either concentration. […] However, the in vitro antiviral activity of hydroxychloroquine at concentrations commonly used in humans was minimal, whether used alone or in combination with lopinavir/ritonavir.
32461326 Tocilizumab was administered to 4 patients and hydroxychloroquine to 1 patient.
32463308 Several pharmacological therapies have been suggested including repurposing of existing drugs such as chloroquine and hydroxychloroquine, sometimes co-administered with azithromycin. […] Chloroquine and hydroxychloroquine were developed in the World War II era for treatment and prophylaxis of malaria, long before modern drug safety surveillance programs. […] How should we proceed with the use of chloroquine and hydroxychloroquine, potentially combined with azithromycin, for COVID-19 given that these agents bring some cardiac toxicity risk and their mechanisms for cardiac toxicity may not be the same?
32463348 Background Despite a lack of clinical evidence, hydroxychloroquine and azithromycin are being administered widely to patients with verified or suspected COVID-19. […] Methods and Results We performed a case series of COVID-19 positive/suspected patients admitted between 2/1/2020 and 4/4/2020 who were treated with azithromycin, hydroxychloroquine, or a combination.

[…] Hydroxychloroquine was found to decrease the viral replication in a concentration-dependent manner in vitro and to be more active when added prior to the viral challenge. […] Thus, we propose a hydroxychloroquine sulphate dose regimen of 400 mg twice daily at Day 1 then 400 mg once daily from Day 2 to Day 10.
32473310 A few clinically approved drugs, such as remdesivir, chloroquine, hydroxychloroquine, nafamostat, camostat, and ivermectin, exhibited anti-SARS-CoV-2 activity in vitro and/or in a small number of patients. […] Bexarotene demonstrated the highest Cmax:EC50 ratio (1.69) which was higher than those of chloroquine, hydroxychloroquine, and ivermectin.
32469265 The role of Chloroquine and Hydroxychloroquine as potential treatments for Covid-19 is still under debate globally because of some side effects associated with it. […] This study involves the In silico interactions of Chloroquine and Hydroxychloroquine with the S-protein of SARS-CoV-2. […] In our research Hydroxychloroquine exhibited potential inhibitory effectsof S-protein with binding energy -7.28 kcal/mol than Chloroquine (-6.30 kcal/mol) at SARS-CoV-2 receptor recognition of susceptible cells. […] The outcomes of this research strongly appeal for in vivo trials of Hydroxychloroquine for the patients infected with Covid-19. […] Furthermore, the recommended doses of Hydroxychloroquine may reduce the chances of catching Covid-19 to the healthcare workers and staff who are in contact with or delivering direct care to coronavirus patients as long as they have not been diagnosed with Covid-19.
32470470 Current treatment of COVID-19 patients relies mainly on antiviral drugs lopinavir/ritonavir, arbidol, and remdesivir, the anti-malarial drugs hydroxychloroquine and chloroquine, and traditional Chinese medicine.
32473681 In logistic regression analysis, independent factors associated with increased 30-day mortality, after partial adjustment, were: increased age (per 10 years; partially adjusted odds ratio 1·84, 95% CI 1·53-2·21), male sex (1·63, 1·07-2·48), smoking status (former smoker vs never smoked: 1·60, 1·03-2·47), number of comorbidities (two vs none: 4·50, 1·33-15·28), Eastern Cooperative Oncology Group performance status of 2 or higher (status of 2 vs 0 or 1: 3·89, 2·11-7·18), active cancer (progressing vs remission: 5·20, 2·77-9·77), and receipt of azithromycin plus hydroxychloroquine (vs treatment with neither: 2·93, 1·79-4·79; confounding by indication cannot be excluded).
32473812 Chloroquine and hydroxychloroquine are drugs that have shown in vitro activity on the replication of certain coronaviruses. […] The results of the first clinical studies evaluating the effect of hydroxychloroquine do not support any efficacy of this drug in patients with COVID-19, due to major methodological weaknesses. […] In the absence of evidence of clinical benefits, the main risk is of exposing patients unnecessarily to the well-known adverse effects of hydroxychloroquine, with a possibly increased risk in the specific setting of COVID-19. […] Meanwhile, serious adverse drug reactions have been reported in patients with COVID-19 receiving hydroxychloroquine, justifying to limit its prescription, and to perform suitable cardiac and therapeutic drug monitoring.
32474476 Given the lack of antiviral therapies or vaccines for the disease, the antimalarial drug hydroxychloroquine (HCQ) obtained much attention as a treatment for COVID-19.

32493478 Primary Objective • To test the efficacy of Hydroxychloroquine (HCQ) (400 mg orally daily for 3 days then 200 mg orally daily for an additional 11 days, to complete 14 days) to prevent incident SARS-CoV-2 infection, compared to ascorbic acid among contacts of persons with SARS-CoV-2 infection Secondary objectives • To determine the safety and tolerability of HCQ as SARS-CoV-2 Post-exposure Prophylaxis (PEP) in adults • To test the efficacy of HCQ (400 mg orally daily for 3 days then 200 mg orally daily for an additional 11 days, to complete 14 days) to prevent incident SARS-CoV-2 infection 2 weeks after completing therapy, compared to ascorbic acid among contacts of persons with SARS-CoV-2 infection • To test the efficacy of HCQ to shorten the duration of SARS-CoV-2 shedding among those with SARS-CoV-2 infection in the HCQ PEP group • To test the efficacy of HCQ to prevent incident COVID-19 TRIAL DESIGN: This is a randomized, multi-center, placebo-equivalent (ascorbic acid) controlled, blinded study of HCQ PEP for the prevention of SARS-CoV-2 infection in adults exposed to the virus.
32493494 Currently there is no accepted chemoprophylaxis but hydroxychloroquine (HDQ) is known to inhibit the coronavirus in vitro. […] Our hypothesis is that oral administration of hydroxychloroquine to healthcare professionals can reduce the incidence and prevalence of infection as well as its severity in this group. […] Exclusion criteria include previous infection with SARS CoV2 (positive SARS-CoV-2 PCR or IgG serology), pregnancy or lactation, any contraindication to hydroxychloroquine or evidence of unstable or clinically significant systemic disease. […] Patients will be randomized (1:1) to receive once-daily oral Hydroxychloroquine 200mg for two months (HC group) or placebo (P group) in addition to the protective measures appropriate to the level of exposure established by the hospital. […] Some evidence of the in vitro efficacy of hydroxychloroquine against this virus is known, along with some clinical data that would support the study of this drug in the chemoprophylaxis of infection. […] If our hypothesis is confirmed, hydroxychloroquine can help professionals fight this infection with more guarantees. […] 1) Previous infection with SARS CoV2 (positive coronavirus PCR or positive serology with SARS Cov2 negative PCR and absence of symptoms); 2) Current treatment with hydroxychloroquine or chloroquine; 3) Hypersensitivity, allergy or any contraindication for taking hydroxychloroquine, in the technical sheet; 4) Previous or current treatment with tamoxifen or raloxifene; 5) Previous eye disease, especially maculopathy; 6) Known heart failure (Grade III to IV of the New York Heart Association classification) or prolonged QTc; 7) Any type of cancer (except basal cell) in the last 5 years; 6) Refusal to give informed consent; 8) Evidence of any other unstable or clinically significant untreated immune, endocrine, hematological, gastrointestinal, neurological, neoplastic or psychiatric illness; 9) Antibodies positive for the human immunodeficiency virus; 10) Significant kidney or liver disease; 11) Pregnancy or lactation. […] 1)Intervention: (n = 225): One 200 mg hydroxychloroquine sulfate coated tablet once daily for two months.2)Comparator (control group) (n = 225): One hydroxychloroquine placebo tablet (identical to that of the drug) once daily for two months MAIN OUTCOMES: The primary outcome of this study will be to evaluate: number and percentage of healthcare personnel presenting symptomatic and asymptomatic infection (see “Diagnosis of SARS CoV2 infection” below) by the SARS-Cov2 virus during the study observation period (8 weeks) in both treatment arms;number and percentage of healthcare personnel in each group presenting with Pneumonia with severity criteria (Curb 65 ≥2) and number and percentage of healthcare personnel requiring admission to the Intensive Care Unit (ICU) in both treatment arms.
32493514 Immunosuppressive therapy (e.g. mycophenolate, azathioprine, methotrexate, biologicals, prednisolone >10mg/d; exceptions are: prednisolone ≤ 10mg/d, sulfasalazine or hydroxychloroquine)9.
32493740 We included studies of ribavirin, chloroquine, hydroxychloroquine, umifenovir (arbidol), favipravir, interferon and lopinavir/ritonavir.
32494896 One hundred fifty-five of 498 (31%) reported regular use of hydroxychloroquine/chloroquine (HCQ) + azithromycin (AZM); concomitant use of AZM was more common in the USA.
32495148 Hydroxychloroquine was recently promoted in patients infected with COVID-19 infection. […] A recent experimental study has suggested an increased toxicity of hydroxychloroquine in association with metformin in mice. […] The present study was undertaken to investigate the reality of this putative drug-drug interaction between hydroxychloroquine and metformin using pharmacovigilance data. […] Data with hydroxychloroquine (or metformin) alone were compared with the association hydroxychloroquine + metformin. […] Of the 10,771 Individual Case Safety Reports (ICSR) involving hydroxychloroquine, 52 were recorded as ‘fatal outcomes’. […] In comparison with hydroxychloroquine alone, hydroxychloroquine + metformin was associated with an ROR value of 57.7 (23.9-139.3). […] In comparison with metformin alone, hydroxychloroquine + metformin was associated with an ROR value of 6.0 (2.6-13.8). […] Our study identified a signal for the association hydroxychloroquine + metformin that appears to be more at risk of fatal outcomes (particularly by completed suicides) than one of the two drugs when given alone.
32495226 Hydroxychloroquine and chloroquine are among the proposed drugs and are the most widely used so far, despite the lack of robust evidence on their usefulness.
32495913 A nasal swab for COVID-19 was performed, which resulted positive, and so therapy with doxycycline, hydroxychloroquine and antiviral agents was started.
32495921 Hence, based upon limited in-vitro and anecdotal data, Chloroquine, or Hydroxychloroquine, Remdesivir, Lopinavir and Ritonavir are being employed in the management.
32496241 Hydroxychloroquine (HCQ), an antimalarial has been proposed as possible treatment for coronavirus disease-2019 (COVID-19).
32496265 All high-risk contacts were given hydroxychloroquine prophylaxis.
32496357 Eighty-percent received hydroxychloroquine ± azithromycin.
32496926 Among the drugs under investigation, anti-malarials, chloroquine (CQ) and hydroxychloroquine (HCQ), are being repurposed as treatment for COVID-19.
32496938 Use of hydroxychloroquine has been popularised on mass media and put forward as a valid treatment option without strong evidence of efficacy. […] Hydroxychloroquine (HCQ) has its own side effects, some of which are very serious like acute haemolysis in glucose-6-phosphate dehydrogenase (G6PD) deficient patients.
32498085 The use of modified protocols for insulin administration, bedside glucose monitoring, and medications such as glucocorticoids and hydroxychloroquine that may affect glycemic control are discussed.
32500556 We read with great interest the recent article by Beauverd et al.1 on an interesting case of severe hemolysis in a patient with COVID-19 treated with hydroxychloroquine. […] However, the article also suggested that hydroxychloroquine possibly worsened the hemolysis, and further cautioned the use of hydroxychloroquine in glucose-6-phosphate dehydrogenase (G6PD)-deficient patients. […] We would like to comment on the authors’ attribution of accentuated hemolysis to the use of hydroxychloroquine.
32501454 We included consecutive patients (aged ≥18 years) with COVID-19, moderate-to-severe ARDS, and hyperinflammation (defined as serum C-reactive protein ≥100 mg/L, ferritin ≥900 ng/mL, or both) who were managed with non-invasive ventilation outside of the ICU and who received standard treatment of 200 mg hydroxychloroquine twice a day orally and 400 mg lopinavir with 100 mg ritonavir twice a day orally.
32501511 To define pediatric-specific dosing regimens for hydroxychloroquine and remdesivir for COVID-19 treatment. […] Physiologically based pharmacokinetic modeling was used to inform pediatric dosing for hydroxychloroquine. […] Simulated drug exposures following a 5-day course of hydroxychloroquine (400 mg every 12 hours × 2 doses followed by 200 mg every 12 hours × 8 doses) and a single 200-mg intravenous dose of remdesivir were computed for simulated adult participants. […] The primary outcome for hydroxychloroquine was average unbound plasma concentrations for 5 treatment days. […] For hydroxychloroquine, the physiologically based pharmacokinetic model analysis included 500 and 600 simulated white adult and pediatric participants, respectively, and supported weight-normalized dosing for children weighing less than 50 kg. […] Simulated unbound hydroxychloroquine concentrations in lung interstitial fluid mirrored those in unbound plasma and were notably lower than in vitro concentrations needed to mediate antiviral activity. […] This analysis provides pediatric-specific dosing suggestions for hydroxychloroquine and remdesivir and raises concerns regarding hydroxychloroquine use for COVID-19 treatment because concentrations were less than those needed to mediate an antiviral effect.
32503662 The hypothesis of the study is that treatment with hydroxychloroquine sulphate in hospitalised patients with coronavirus disease 2019 (Covid-19) is safe and will accelerate the virological clearance rate for patients with moderately severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) when compared to standard care. […] Furthermore, we hypothesize that early treatment with hydroxychloroquine sulphate is associated with more rapid resolve of clinical symptoms as assessed by the National Early Warning Score 2 (NEWS2), decreased admission rate to intensive care units and mortality, and improvement in protein biomarker profiles (C-reactive protein, markers of renal and hepatic injury, and established cardiac biomarkers like cardiac troponin and B-type natriuretic peptide). […] The study is a two-arm, open label, pragmatic randomised controlled group sequential adaptive trial designed to assess the effect on viral loads and clinical outcome of hydroxychloroquine sulphate therapy in addition to standard care compared to standard care alone in patients with established Covid-19. […] Patients will be excluded from participation in the study if they meet any of the following criteria: (1) Requiring intensive care unit admission at screening; (2) History of psoriasis; (3) Known adverse reaction to hydroxychloroquine sulphate; (4) Pregnancy; or (5) Prolonged corrected QT interval (>450 ms). […] Included patients will be randomised in a 1:1 ratio to (1) standard care with the addition of 400 mg hydroxychloroquine sulphate (PlaquenilTM) twice daily for seven days or (2) standard care alone.
32505076 Combined treatment with hydroxychloroquine and azithromycin improves the outcome of Covid-19 in lung cancer patients, detecting only 1/6 deaths between patients under this treatment versus others treatment, with statistical significance in the univariate and multivariate logistic regression (OR 0.04, p = 0.018). […] Combined hydroxychloroquine and azithromycin treatment seems like a good treatment option.
32509485 She clinically improved on hydroxychloroquine and therapeutic anticoagulation.
32510734 Initial enthusiasm for the combination of hydroxychloroquine and azithromycin has abated.
32510771 We reduced immunosuppressive regimen in all these patients, typically holding the antiproliferative agent and augmenting steroids; everybody received hydroxychloroquine, initial empiric antibiotic treatment with piperacillin/tazobactam, and high-dose low molecular weight heparin.
32512263 Patients on hydroxychloroquine, TNFα antagonists or tocilizumab may have a mild viral illness.
32512873 Initial experiences with the use of hydroxychloroquine to prevent COVID-19 also seem promising.
32513231 To determine the efficacy of Hydroxychloroquine vs. […] Hydroxychloroquine + Nitazoxanide in reducing the need for invasive mechanical ventilatory support for patients with COVID-19. […] Hydroxychloroquine is currently being used in multiple trials with varying doses in an attempt to treat COVID-19. […] Dual therapy by combining appropriate doses of these two medications with diverse activities against COVID-19 is expected to be better than monotherapy with hydroxychloroquine. […] Elimination criteria: 1)Patients whose clinical follow-up is lost or who decide not to continue in the study INTERVENTION AND COMPARATOR: The two management alternatives will be: Control - Hydroxychloroquine 200 mg taken orally every 12 hours for 7 days. […] Dual therapy - Hydroxychloroquine 400 mg taken orally every 12 hours for two days and then 200 mg taken orally every 12 hours for four days + Nitazoxanide 500 mg orally every 6 hours taken with food, for seven days.
32514228 Certain drugs that are clinically approved for other diseases were tested against COVID-19 as chloroquine, hydroxychloroquine, ivermectin, favipiravir, ribavirin, and remdesivir.
32514696 Recent attention on the possible use of hydroxychloroquine and chloroquine to treat COVID-19 disease has potentially triggered a number of overdoses from hydroxychloroquine. […] Toxicity from hydroxychloroquine manifests with cardiac conduction abnormalities, seizure activity, and muscle weakness. […] A 27-year-old man with a history of rheumatoid arthritis presented to the emergency department 7 hours after an intentional overdose of hydroxychloroquine. […] Hydroxychloroquine toxicity is rare but projected to increase in frequency given its selection as a potential modality to treat COVID-19 disease. […] It is important for clinicians to recognize the unique effects of hydroxychloroquine poisoning and initiate appropriate emergency maneuvers to improve the outcomes in these patients.
32515383 Hydroxychloroquine/chloroquine, Interferon-l, glucocorticoids, interleukin antagonists, Ulinastatin, intravenous immunoglobulins, plasmapheresis are main immunomodulators showing initial positive outcomes.
32517786 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.
32519117 In the future ophthalmologists could play a decisive role in the screening of maculopathies that might occur during COVID-19 treatment using chloroquine or hydroxychloroquine.
32519281 Hydroxychloroquine has been promoted for its use in treatment of COVID-19 patients based on in-vitro evidences. […] We searched the databases to include randomized and observational studies evaluating the effect of Hydroxychloroquine on mortality in COVID-19 patients. […] In all studies, Hydroxychloroquine was given as add on to the standard care and effect was compared with the standard care alone. […] A pooled analysis observed 251 deaths in 1331 participants of the Hydroxychloroquine arm and 363 deaths in 1577 participants of the control arm. […] There was no difference in odds of mortality events amongst Hydroxychloroquine and supportive care arm [1.25 (95% CI: 0.65, 2.38); I2 = 80%]. […] The odds of mortality were significantly higher in patients treated with Hydroxychloroquine + Azithromycin than supportive care alone [2.34 (95% CI: 1.63, 3.34); I2 = 0%]. […] A pooled analysis of recently published studies suggests no additional benefit for reducing mortality in COVID-19 patients when Hydroxychloroquine is given as add-on to the standard care.
32519406 Hydroxychloroquine was started and continued for 7 days.
32519617 He received treatment with hydroxychloroquine (400 mg/day).
32519786 Hydroxychloroquine (600mg/day), Azithromycine, steroids (dexamethasone 20mg/day), vitamin C (3g/day), Zinc, diuretics and Enoxaparine were equally used for the two patients.
32520683 After the publication of hydroxychloroquine (HCQ) with anti-SARS-COV-2 activity in vitro, a small, non-randomized, open-label clinical trial showed that HCQ treatment was significantly associated with reduced viral load in patients with coronavirus disease-19 (COVID-19). […] Use the keyword ‘Hydroxychloroquine’ to conduct a literature search in PubMed to collect relevant literature on the mechanism of action of HCQ, clinical efficacy and safety, pharmacokinetic characteristics, precautions for clinical use and drug interactions, and extract and organize information.
32522067 Although several known drugs are already under clinical evaluation with many in repositioning strategies, much attention has been paid to the aminoquinoline derivates, chloroquine (CQ) and hydroxychloroquine (HCQ). […] In this short perspective, we discuss the roles of CQ/HCQ in the treatment of COVID-19 patients and propose new ways of possible treatment for SARS-CoV-2 infection based on the molecules that selectivity target autophagy.Abbreviation: ACE2: angiotensin I converting enzyme 2; CoV: coronavirus; CQ: chloroquine; ER: endoplasmic reticulum; HCQ: hydroxychloroquine; MERS-CoV: Middle East respiratory syndrome coronavirus; SARS-CoV: severe acute respiratory syndrome coronavirus; SARS-CoV-2: severe acute respiratory syndrome coronavirus 2.
32522282 The aim of this randomised GCP-controlled trial is to clarify whether combination therapy with the antibiotic azithromycin and hydroxychloroquine via anti-inflammation/immune modulation, antiviral efficacy and pre-emptive treatment of supra-infections can shorten hospitalisation duration for patients with COVID-19 (measured as “days alive and out of hospital” as the primary outcome), reduce the risk of non- invasive ventilation, treatment in the intensive care unit and death. […] Fertile women* must not be pregnant, i.e. negative pregnancy test must be available at inclusion • Informed consent signed by the patient *Defined as after menarche and until postmenopausal (no menstruation for 12 months) Exclusion criteria: • At the time of recruitment, the patient uses >5 LO2/min (equivalent to 40% FiO2 if measured) • Known intolerance/allergy to azithromycin or hydroxychloroquine or hypersensitivity to quinine or 4-aminoquinoline derivatives • Neurogenic hearing loss • Psoriasis • Retinopathy • Maculopathy • Visual field changes • Breastfeeding • Severe liver diseases other than amoebiasis (INR> 1.5 spontaneously) • Severe gastrointestinal, neurological and hematological disorders (investigator-assessed) • eGFR <45 ml/min/1.73 m2 • Clinically significant cardiac conduction disorders/arrhythmias or prolonged QTc interval (QTc (f) of> 480/470 ms). […] Hydroxychloroquine: Furthermore, the patient will be treated with hydroxychloroquine as follows: Day 1-15: 200 mg x 2 MAIN OUTCOMES: • Number of days alive and discharged from hospital within 14 days (summarises both whether the patient is alive and discharged from hospital) (“Days alive and out of hospital”) RANDOMISATION: The sponsor (Chronic Obstructive Pulmonary Disease Trial Network, COP:TRIN) generates a randomisation sequence.
32522754 A rapid recovery of respiratory and general symptoms was observed after 1 week of treatment with lopinavir/ritonavir plus hydroxychloroquine and broad-spectrum antibiotics (piperacillin-tazobactam plus teicoplanin).
32523150 The use of chloroquine/hydroxychloroquine, azithromycin and antiviral treatment and has been proposed by various groups, supported by in-vitro studies and limited patient series, without the adequate scientific rigor that precedes drug prescription.
32524645 We comment on hydroxychloroquine, chloroquine, lopinavir/ritonavir with zinc supplement, remdesivir, tocilizumab, ciclesonide, niclosamide and high-dose intravenous immunoglobulin (IVIG).
32526507 Here we propose to use low doses of hydroxychloroquine (50-100 mg daily orally) and intranasal interferon alpha-2b (IFN α-2b) spray (0.5 × 106 IU twice daily) for the prophylaxis of COVID-19. […] Although there are ongoing clinical trials to test the efficacy of hydroxychloroquine for prophylaxis, there has not been any proposal to test the efficacy of IFN α-2b together with hydroxychloroquine to increase protection against COVID-19.
32528194 In the absence of a vaccine and an effective antiviral chemotherapy, there is currently an intense global interest in repositioning chloroquine (CQ) and its derivative hydroxychloroquine (HCQ) to combat the pandemic.
32529737 Hydroxychloroquine was considered in both strategies but antivirals in none.
32531620 Various treatment regimens including interferon, antivirals, and hydroxychloroquine therapies have been trialed on the pediatric population but there are currently no studies showing efficacy of one regimen over the other.
32531808 We use a mechanistic lung model to demonstrate that accumulation of chloroquine (CQ), hydroxychloroquine (HCQ) and azithromycin (AZ) in the lungs is sensitive to changes in lung pH, a parameter that can be affected in patients with COVID-19.
32532805 If this hypothesis is correct, hydroxychloroquine, spirulina (more specifically, its chromophore phycocyanobilin) and high-dose glycine may have practical potential for mitigating the elevated thrombotic risk associated with COVID-19.
32532939 Hydroxychloroquine, lopinavir/ritonavir, remdesivir, umifenovir, favipiravir, ribavirin and beta-interferon-1 gave rise to variable but still inconsistent proof of clinical efficacy in the treatment of COVID-19.
32532948 A 71-year old gentleman with history of arterial hypertension treated with valsartan presented on was hospitalized at the Infectious Diseases Unit, University of Bologna (Italy) for severe acute respiratory syndrome- coronavirus-2 (SARS-CoV-2) and received treatment with hydroxychloroquine 200mg bid (400 mg bid the first day), azithromycin 400 mg qd, thrombotic prophylaxis with enoxaparin 4000 UI qd and Venturi mask oxygen delivering FiO2 of 31%.
32533263 The co-administration of hydroxychloroquine with azithromycin is proposed in COVID-19 therapy. […] This additional mechanism may therefore explain the synergistic effect when azithromycin is added to hydroxychloroquine, leading to apparently more rapid virus clearance and better clinical benefit, when compared to monotherapy with hydroxychloroquine alone.
32534189 Some preliminary evidences have demonstrated controversial results regarding efficacy of azithromycin in combination with hydroxychloroquine in COVID-19. […] Firstly, a French trial demonstrated 100% of virological negativization of six patients treated with azithromycin plus hydroxychloroquine vs 57.1% of patients treated with only hydroxychloroquine and 12.5% of the control group (p<0.05). […] Furthermore, there are some concerns regarding the association of azithromycin and hydroxychloroquine because of the potential Qt prolongation.
32534369 The Food and Drug Administration (FDA) warned against the use of Hydroxychloroquine or chloroquine for Covid-19 outside of a hospital or a clinical trial setting due to the risk of QT interval prolongation, ventricular tachycardia and the increased risk of these complications when combined with some antibiotics such as azithromycin. […] Several studies have reported no benefit of Hydroxychloroquine or chloroquine, when used alone or with a macrolide in COVID-19 hospitalized patients. […] Despite these warnings, in several developing countries the official guidelines for treatment of Covid-19 patients at the primary care level recommend Hydroxychloroquine and azithromycin, among other treatments, as the first-choice for mild symptomatic Covid-19 patients, asymptomatic contacts or for prophylaxis.
32536150 The efficacies of lopinavir-ritonavir or hydroxychloroquine remain to be determined in patients with coronavirus disease 2019 (COVID-19). […] To compare the virological and clinical responses to lopinavir-ritonavir and hydroxychloroquine treatment in COVID-19 patients. […] This retrospective cohort study included patients with COVID-19 treated with lopinavir-ritonavir or hydroxychloroquine at a single center in Korea from February 17 to March 31, 2020. […] Patients treated with lopinavir-ritonavir and hydroxychloroquine concurrently and those treated with lopinavir-ritonavir or hydroxychloroquine for less than 7 days were excluded. […] Of 65 patients (mean age, 64.3 years; 25 men [38.5%]), 31 were treated with lopinavir-ritonavir and 34 were treated with hydroxychloroquine. […] Patients treated with lopinavir-ritonavir had a significantly shorter time to negative conversion of viral RNA than those treated with hydroxychloroquine (median, 21 days vs. 28 days). […] There was no significant difference in time to clinical improvement between lopinavir-ritonavir- and hydroxychloroquine-treated patients (median, 18 days vs. 21 days). […] Lymphopenia and hyperbilirubinemia were more frequent in lopinavir-ritonavir-treated patients compared with hydroxychloroquine-treated patients. […] Lopinavir-ritonavir was associated with more rapid viral clearance than hydroxychloroquine in mild to moderate COVID-19, despite comparable clinical responses.
32537099 The results of a clinical trial comparing hydroxychloroquine with or without azithromycin to the standard of care for the treatment of COVID-19 were recently published by Philippe Gautret et al. […] This study provides outstanding results for the combination of hydroxychloroquine and azithromycin over the standard of care, but the evidence was deemed insufficiently robust to warrant a public health decision to widen the use of hydroxychloroquine for the treatment of COVID-19.
32540367 Many potential therapies are currently under investigation, with some, like Hydroxychloroquine, being authorized for emergency use in some countries.

32542964 Well known anti-inflammatory properties of Chloroquine and Hydroxychloroquine, agents widely used in dermatology, made them potential candidates for the treatment of COVID-19. […] In addition, we focus more on Chloroquine and Hydroxychloroquine, their pharmacological properties, clinical utility, and current recommendations for their use in COVID-19.
32544304 Here we summarise the evidence for antiretrovirals to treat COVID-19 and, as a drug that has also been studied in HIV, hydroxychloroquine, and flag some of the pitfalls of using therapies that have not been evaluated robustly.
32544867 All patients received conventional therapy including Hydroxychloroquine, and lopinavir/ritonavir. […] Our findings support the use of IFN-β-1a in combination with hydroxychloroquine and lopinavir/ritonavir in the management of COVID-19.
32546029 Tocilizumab and lenzilumab are recombinant monoclonal antibodies against IL-6 and granulocyte macrophage colony-stimulating factor, respectively, and have been proposed as a potential treatment for acute, hypoxic respiratory failure associated with COVID-19. Results & methodology: We present the case of a 68-year-old man with COVID-19 who was initially treated with hydroxychloroquine and lenzilumab, but continued to develop hypoxemia, requiring an increase in respiratory support with an associated rise in serum inflammatory markers.
32546437 All except two patients (97%; n=61) were treated with either chloroquine or hydroxychloroquine, while the three most prescribed antibiotics were ceftriaxone (79%; n=50), azithromycin (71%; n=45), and the piperacillin/tazobactam combination (49%; n=31).

32555446 According to the information that we have collected so far, this article provides an overview of potential therapeutic drugs and compounds with much attention, including favipiravir and hydroxychloroquine, as well as traditional Chinese medicine, which have been reported with good clinical treatment effects.
32555974 These include chloroquine (CQ), hydroxychloroquine (HCQ), nitazoxanide, remdesivir, Lopinavir/ritonavir (LPV / r), in addition to treatment with convalescent plasma.
32556143 Data from non-randomized studies have suggested that hydroxychloroquine could be an effective therapeutic agent against Covid-19. […] Patients who received hydroxychloroquine (200mg tid dosage for 10 days) on a compassionate basis in addition to SOCwere compared to patients without contraindications to hydroxychloroquine who received SOCalone. […] Data from 89 patients with laboratory-confirmed Covid-19 were analyzed, 84 of whom were considered in the primary analysis; 38 patients treated with hydroxychloroquine and 46 patients treated with SOCalone. […] In hospitalized adults with Covid-19, no significant reduction of the risk of unfavorable outcomes was observed with hydroxychloroquine in comparison to standard of care. […] Ongoing controlled trials in patients with varying degrees of initial severity on a larger scale will help determine whether there is a place for hydroxychloroquine in the treatment of Covid-19.
32557209 Hemodialysis therapy was performed in isolation with hydroxychloroquine administration, but the formation of a dialysis membrane clot forced the withdrawal of dialysis therapy. […] The hydroxychloroquine and appropriate fluid management may have contributed to the patient’s recovery.
32558210 The aim of this life size in vitro pharmacokinetic study was to investigate the in-vitro adsorption of chloroquine and hydroxychloroquine from human plasma using equipment that is also used at the bedside. […] Both drugs were determined using a validated HPLC method Median [IQR] plasma clearance of the Seraph for chloroquine / hydroxychloroquine was 1.71 [0.51-4.38] ml/min / 1.79 [0.21-3.68] ml/min respectively. […] As neither chloroquine nor hydroxychloroquine were removed by the treatment with the Seraph dose adjustments in COVID-19 patients undergoing this treatment are not necessary.
32559354 Her hepatitis and respiratory symptoms improved coincident with completing treatment with hydroxychloroquine, reduced immunosuppression, and intravenous gamma globulin (IVIG).
32559589 The goal of this systematic review is to assess the published literature for seizure risk with chloroquine or hydroxychloroquine therapy in persons with and without epilepsy. […] Chloroquine or hydroxychloroquine is one proposed medication that has received substantial public attention. […] PubMed (1970 to March 27, 2020) and the Embase (1970 to March 27, 2020) were searched with the terms chloroquine or hydroxychloroquine and seizure or epilepsy, convulsions, or status epilepticus. […] For hydroxychloroquine, there was one prospective observational study(n = 631) and one case report. […] The clinical trials failed to find any significant relation between seizures and chloroquine or hydroxychloroquine.
32559820 In the absence of a commonly agreed dosing protocol based on pharmacokinetic considerations, the dose and treatment duration for hydroxychloroquine (HCQ) COVID-19 disease currently vary across national guidelines and clinical study protocols.
