[PMID: 37240153 DOI: 10.3390/ijms24108808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 05/08/2023] [Accepted: 05/12/2023] [Indexed: 05/28/2023] Open
Abstract
This study aimed to evaluate and compare the efficacy of cyclodextrans (CIs) and cyclodextrins (CDs) in improving the water solubility of a poorly water-soluble drug, clofazimine (CFZ). Among the evaluated CIs and CDs, CI-9 exhibited the highest percentage of drug inclusion and the highest solubility. Additionally, CI-9 showed the highest encapsulation efficiency, with a CFZ:CI-9 molar ratio of 0.2:1. SEM analysis indicated successful formation of inclusion complexes CFZ/CI and CFZ/CD, accounting for the rapid dissolution rate of the inclusion complex. Moreover, CFZ in CFZ/CI-9 demonstrated the highest drug release ratio, reaching up to 97%. CFZ/CI complexes were found to be an effective means of protecting the activity of CFZ against various environmental stresses, particularly UV irradiation, compared to free CFZ and CFZ/CD complexes. Overall, the findings provide valuable insights into designing novel drug delivery systems based on the inclusion complexes of CIs and CDs. However, further studies are needed to investigate the effects of these factors on the release properties and pharmacokinetics of encapsulated drugs in vivo, in order to ensure the safety and efficacy of these inclusion complexes. In conclusion, CI-9 is a promising candidate for drug delivery systems, and CFZ/CI complexes could be a potential formulation strategy for the development of stable and effective drug products.

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
OBJECTIVE Randomised controlled trials (RCTs) in systemic lupus erythematosus (SLE, lupus) typically adopt composite responder definitions as primary efficacy endpoints, however outcomes within individual organ domains are also important to understand. The aim of this scoping review was to evaluate how organ-specific disease activity and therapeutic responses have been measured and reported in lupus RCTs. METHODS We searched MEDLINE, EMBASE, Cochrane registry and clinicaltrials.gov. Eligible studies were RCTs investigating efficacy of an immune-directed drug therapy in active SLE, published January 2000-March 2021, excluding studies limited to lupus nephritis. Data were extracted independently in duplicate into a template and summarised descriptively. RESULTS Thirty-four RCTs were included, of which 32 (94%) reported activity and/or responses in at least one organ domain. Study populations had a high, although variable, frequency of baseline musculoskeletal and mucocutaneous activity and low but also variable representation of other domains. Definitions of organ-specific responses were inconsistent, even within individual instruments. Response in most organ domains were evaluated using BILAG and SLEDAI components but meaningful comparison between treatment arms was limited by small subgroups analysed in a post hoc fashion. Specific mucocutaneous and arthritis instruments were also used, including within pre-specified organ-specific endpoints, which discriminated between treatment arms in some studies. CONCLUSION Mucocutaneous and musculoskeletal manifestations predominate in SLE RCTs. Organ-specific outcome measures are commonly reported, but definitions of involvement and response are inconsistent. Research into the development of new outcome measures for key organ domains, and validation and comparison of response definitions using existing instruments, is needed.

Abstract
Cutaneous lupus erythematosus (CLE) is an inflammatory, autoimmune disease encompassing a broad spectrum of subtypes including acute, subacute, chronic and intermittent CLE. Among these, chronic CLE can be further classified into several subclasses of lupus erythematosus (LE) such as discoid LE, verrucous LE, LE profundus, chilblain LE and Blaschko linear LE. To provide all dermatologists and rheumatologists with a practical guideline for the diagnosis, treatment and long-term management of CLE, this evidence- and consensus-based guideline was developed following the checklist established by the international Reporting Items for Practice Guidelines in Healthcare (RIGHT) Working Group and was registered at the International Practice Guideline Registry Platform. With the joint efforts of the Asian Dermatological Association (ADA), the Asian Academy of Dermatology and Venereology (AADV) and the Lupus Erythematosus Research Center of Chinese Society of Dermatology (CSD), a total of 25 dermatologists, 7 rheumatologists, one research scientist on lupus and 2 methodologists, from 16 countries/regions in Asia, America and Europe, participated in the development of this guideline. All recommendations were agreed on by at least 80% of the 32 voting physicians. As a consensus, diagnosis of CLE is mainly based on the evaluation of clinical and histopathological manifestations, with an exclusion of SLE by assessment of systemic involvement. For localized CLE lesions, topical corticosteroids and topical calcineurin inhibitors are first-line treatment. For widespread or severe CLE lesions and (or) cases resistant to topical treatment, systemic treatment including antimalarials and (or) short-term corticosteroids can be added. Notably, antimalarials are the first-line systemic treatment for all types of CLE, and can also be used in pregnant patients and pediatric patients. Second-line choices include thalidomide, retinoids, dapsone and MTX, whereas MMF is third-line treatment. Finally, pulsed-dye laser or surgery can be added as fourth-line treatment for localized, refractory lesions of CCLE in cosmetically unacceptable areas, whereas belimumab may be used as fourth-line treatment for widespread CLE lesions in patients with active SLE, or recurrence of ACLE during tapering of corticosteroids. As for management of the disease, patient education and a long-term follow-up are necessary. Disease activity, damage of skin and other organs, quality of life, comorbidities and possible adverse events are suggested to be assessed in every follow-up visit, when appropriate.

Abstract
BACKGROUND Lupus erythematosus is an autoimmune disease with significant morbidity and mortality. Cutaneous disease in systemic lupus erythematosus (SLE) is common. Many interventions are used to treat SLE with varying efficacy, risks, and benefits. OBJECTIVES To assess the effects of interventions for cutaneous disease in SLE. SEARCH METHODS We searched the following databases up to June 2019: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, Wiley Interscience Online Library, and Biblioteca Virtual em Saude (Virtual Health Library). We updated our search in September 2020, but these results have not yet been fully incorporated. SELECTION CRITERIA We included randomised controlled trials (RCTs) of interventions for cutaneous disease in SLE compared with placebo, another intervention, no treatment, or different doses of the same intervention. We did not evaluate trials of cutaneous lupus in people without a diagnosis of SLE. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Primary outcomes were complete and partial clinical response. Secondary outcomes included reduction (or change) in number of clinical flares; and severe and minor adverse events. We used GRADE to assess the quality of evidence. MAIN RESULTS Sixty-one RCTs, involving 11,232 participants, reported 43 different interventions. Trials predominantly included women from outpatient clinics; the mean age range of participants was 20 to 40 years. Twenty-five studies reported baseline severity, and 22 studies included participants with moderate to severe cutaneous lupus erythematosus (CLE); duration of CLE was not well reported. Studies were conducted mainly in multi-centre settings. Most often treatment duration was 12 months. Risk of bias was highest for the domain of reporting bias, followed by performance/detection bias. We identified too few studies for meta-analysis for most comparisons. We limited this abstract to main comparisons (all administered orally) and outcomes. We did not identify clinical trials of other commonly used treatments, such as topical corticosteroids, that reported complete or partial clinical response or numbers of clinical flares. Complete clinical response Studies comparing oral hydroxychloroquine against placebo did not report complete clinical response. Chloroquine may increase complete clinical response at 12 months' follow-up compared with placebo (absence of skin lesions) (risk ratio (RR) 1.57, 95% confidence interval (CI) 0.95 to 2.61; 1 study, 24 participants; low-quality evidence). There may be little to no difference between methotrexate and chloroquine in complete clinical response (skin rash resolution) at 6 months' follow-up (RR 1.13, 95% CI 0.84 to 1.50; 1 study, 25 participants; low-quality evidence). Methotrexate may be superior to placebo with regard to complete clinical response (absence of malar/discoid rash) at 6 months' follow-up (RR 3.57, 95% CI 1.63 to 7.84; 1 study, 41 participants; low-quality evidence). At 12 months' follow-up, there may be little to no difference between azathioprine and ciclosporin in complete clinical response (malar rash resolution) (RR 0.83, 95% CI 0.46 to 1.52; 1 study, 89 participants; low-quality evidence). Partial clinical response Partial clinical response was reported for only one key comparison: hydroxychloroquine may increase partial clinical response at 12 months compared to placebo, but the 95% CI indicates that hydroxychloroquine may make no difference or may decrease response (RR 7.00, 95% CI 0.41 to 120.16; 20 pregnant participants, 1 trial; low-quality evidence). Clinical flares Clinical flares were reported for only two key comparisons: hydroxychloroquine is probably superior to placebo at 6 months' follow-up for reducing clinical flares (RR 0.49, 95% CI 0.28 to 0.89; 1 study, 47 participants; moderate-quality evidence). At 12 months' follow-up, there may be no difference between methotrexate and placebo, but the 95% CI indicates there may be more or fewer flares with methotrexate (RR 0.77, 95% CI 0.32 to 1.83; 1 study, 86 participants; moderate-quality evidence). Adverse events Data for adverse events were limited and were inconsistently reported, but hydroxychloroquine, chloroquine, and methotrexate have well-documented adverse effects including gastrointestinal symptoms, liver problems, and retinopathy for hydroxychloroquine and chloroquine and teratogenicity during pregnancy for methotrexate. AUTHORS' CONCLUSIONS Evidence supports the commonly-used treatment hydroxychloroquine, and there is also evidence supporting chloroquine and methotrexate for treating cutaneous disease in SLE. Evidence is limited due to the small number of studies reporting key outcomes. Evidence for most key outcomes was low or moderate quality, meaning findings should be interpreted with caution. Head-to-head intervention trials designed to detect differences in efficacy between treatments for specific CLE subtypes are needed. Thirteen further trials are awaiting classification and have not yet been incorporated in this review; they may alter the review conclusions.

Abstract
Glucocorticoids (GCs) use is associated with increased organ damage in systemic lupus erythematosus (SLE), and the treatment goal is to stop their use. Treatment with hydroxychloroquine (HCQ) without daily GCs may benefit patients by minimising the cumulative dose of GCs, but clinical experience with HCQ monotherapy is limited. To accumulate evidence for initial HCQ monotherapy in SLE, we retrospectively analysed three new SLE patients who visited Yokohama City University Hospital in 2015. The patients were all Japanese females with a mean age of 26.0 ± 5.3 years, high anti-dsDNA antibody titres, no major organ damage, and a mean pre-treatment Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score of 9.3 ± 3.1. During the mean observation period of 3.8 ± 0.8 years, none of them received daily GCs or immunosuppressants, but one of the three patients were treated with short-term oral GCs and NSAIDs for a skin rash or arthralgia flairs. SLEDAI-2K was reduced to 3.3 ± 1.2. No other new SLE symptoms emerged, and the Systemic Lupus International Collaborating Clinics Damage Index (SDI) of them were maintained at 0. None of the patients developed HCQ-related retinal toxicity. Current experience with initial HCQ monotherapy suggests that such a therapeutic strategy may be useful in managing disease activity and preserving cumulative GCs in SLE patients without organ involvements.

Abstract
The characteristics of the biology of influenza viruses and coronavirus that determine the implementation of the infectious process are presented. With provision for pathogenesis of infection possible effects of serine proteinase inhibitors, heparin, and inhibitors of heparan sulfate receptors in the prevention of cell contamination by viruses are examined. It has been determined that chelators of metals of variable valency and antioxidants should be used for the reduction of replicative activity of viruses and anti-inflammatory therapy. The possibility of a pH-dependent impairment of glycosylation of cellular and viral proteins was traced for chloroquine and its derivatives. The use of low-toxicity drugs as part of adjunct therapy increases the effectiveness of synthetic antiviral drugs and interferons and ensures the safety of baseline therapy.

Abstract
BACKGROUND Chloroquine (CQ) and its derivative hydroxychloroquine (HCQ) have recently emerged as potential antiviral and immunomodulatory options for the treatment of 2019 coronavirus disease (COVID-19). To examine the safety profiles of these medications, we systematically evaluated the adverse events (AEs) of these medications from published randomized controlled trials (RCTs). METHODS We systematically searched MEDLINE, the Cochrane library, the Cochrane Central Register of Controlled Trials (CENTRAL), and the ClinicalTrials.gov for all the RCTs comparing CQ or HCQ with placebo or other active agents, published before June 20, 2020. The random-effects or fixed-effects models were used to pool the risk estimates relative ratio (RR) with 95% confidence interval (CI) for the outcomes. RESULTS The literature search yielded 23 and 19 studies for CQ and HCQ, respectively, that satisfied our inclusion criteria. Of these studies, we performed meta-analysis on 6 studies for CQ and 18 studies for HCQ. We did not limit our analysis to published records involving viral treatment alone; data also included the usage of either CQ or HCQ for the treatment of other diseases. The trials for the CQ consisted of a total of 2,137 participants (n = 1,077 CQ, n = 1,060 placebo), while the trials for HCQ involved 2,675 participants (n = 1,345 HCQ and n = 1,330 control). The overall mild and total AEs were significantly higher in CQ-treated non-COVID-19 patients, HCQ-treated non-COVID-19 patients, and HCQ-treated COVID-19 patients. The AEs were further categorized into four groups and analyses revealed that neurologic, gastrointestinal (GI), dermatologic, and sensory AEs were higher in participants taking CQ compared to placebo, while GI, dermatologic, sensory, and cardiovascular AEs were higher in HCQ-treated COVID-19 patients compared to control patients. Moreover, subgroup analysis suggested higher AEs with respect to dosage and duration in HCQ group. Data were acquired from studies with perceived low risk of bias, so plausible bias is unlikely to seriously affect the main findings of the current study. CONCLUSIONS Taken together, we found that participants taking either CQ or HCQ exhibited more AEs than participants taking placebo or control. Precautionary measures should be taken when using these drugs to treat COVID-19. The meta-analysis was registered on OSF (https://osf.io/jm3d9).

Abstract
Influenza virus and coronaviruses continue to cause pandemics across the globe. We now have a greater understanding of their functions. Unfortunately, the number of drugs in our armory to defend us against them is inadequate. This may require us to think about what mechanisms to address. Here, we review the biological properties of these viruses, their genetic evolution and antiviral therapies that can be used or have been attempted. We will describe several classes of drugs such as serine protease inhibitors, heparin, heparan sulfate receptor inhibitors, chelating agents, immunomodulators and many others. We also briefly describe some of the drug repurposing efforts that have taken place in an effort to rapidly identify molecules to treat patients with COVID-19. While we put a heavy emphasis on the past and present efforts, we also provide some thoughts about what we need to do to prepare for respiratory viral threats in the future.

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.

The overall mild or total AEs were statistically higher comparing CQ or HCQ to placebo. The AEs were further categorized into four groups and analyses revealed that neurologic, gastrointestinal, dermatologic, and ophthalmic AEs were higher in participants taking CQ compared to placebo. Although this was not evident in HCQ treated groups, further analyses suggested that there were more AEs attributed to other organ system that were not included in the categorized meta-analyses. Additionally, meta-regression analyses revealed that total AEs was affected by dosage for the CQ group. CONCLUSIONS Taken together, we found that participants taking either CQ or HCQ have more AEs than participants taking placebo. Precautionary measures should be taken when using these drugs to treat COVID-19.

Abstract
Discoid lupus erythematosus is the most disfiguring and common presentation of chronic cutaneous lupus erythematosus. Although most patients will respond to lifestyle measures and topical treatment, a non-negligible number of patients will require systemic and physical therapy, either alone or in combination. We performed a review of the available evidence on the discoid lupus erythematosus treatment. Lifestyle measures and topical treatment (corticosteroids and topical calcineurin inhibitors) remain the therapeutic strategies with the highest evidence level. Within systemic treatment approaches, antimalarial drugs are still the first-line therapy, while other systemic and physical therapies have highly variable evidence. Hence, we propose a therapeutic algorithm based on the strength of recommendations of the different treatment modalities, focusing on the refractory disease.

Abstract
BACKGROUND Cutaneous lupus erythematosus (CLE), occurring with or without systemic lupus erythematosus (SLE), is a group of inflammatory skin diseases that can be very debilitating, causing significant psychological distress, and sometimes scarring. OBJECTIVES We sought to comprehensively present the evidence for different treatment modalities in patients with cutaneous manifestations of lupus erythematosus (LE). METHODS Medline, Embase, Scopus and Cochrane CENTRAL were searched electronically from 1990 to March 2019, using keywords related to cutaneous lupus and synonyms and treatment. Articles retrieved were screened for relevance, including reference lists of retrieved reviews. We included clinical trials, observational studies or case series with ≥5 patients focussing on treatment of CLE, with or without SLE. RESULTS The search identified 6637 studies, of which 107 were included. Each study commonly included a heterogeneous mixture of CLE subtypes, with or without SLE. The 107 included studies investigated 11 different categories of treatment in 7343 patients. Treatments included topical calcineurin inhibitors (13 studies), sun protection (5 studies), R-salbutamol cream (2 studies), antimalarials (22 studies), synthetic DMARDs (10 studies), retinoids (2 studies), thalidomide/lenalidomide (22 studies), biologic therapies (15 studies), intravenous immune globulin (3 studies), laser (6 studies) and other therapies (7 studies). General measures to be considered include smoking cessation, sun protection measures and optimisation of vitamin D levels. Moderate evidence exists for benefit with topical CNIs, particularly as a steroid sparing agent in areas at high risk of steroid complications (e.g. facial skin). There is moderate evidence for hydroxychloroquine, which is first-line in SLE patients, limited evidence to support other synthetic DMARDs, and moderate evidence supporting thalidomide but with significant risk of toxicity. Of biologic therapies, there are moderate data to support belimumab. Limited evidence exists for other therapies. CONCLUSION Many management options are available for CLE, including topical, systemic and biologic therapies, with a variable balance of efficacy and toxicity. There is a paucity of high-quality clinical trial data. Further trials are required to better understand optimal management of CLE, particularly in specific subgroups.

Abstract
This longitudinal retrospective study aims at describing the safety profile and the reasons for discontinuation of antimalarials in patients with systemic lupus erythematosus (SLE) and discoid lupus erythematosus (DLE), focusing on ocular toxicity. We analyzed the clinical data of 845 SLE and DLE patients; 59% of them were taking antimalarials: 1.4% chloroquine (CQ), 88.5% hydroxychloroquine (HCQ) and 10.1% both. The mean therapy duration was 82.5 ± 77.4 months. At least one side effect was reported by 19.4% of patients, leading to temporary or permanent withdrawal in 9.1% and 10.3% of cases, respectively; 19.3% of patients experienced side effects with HCQ and 8.6% with CQ. In 55.1% of cases, the adverse event was mild or moderate. Ophthalmological alterations were reported by 8.5% but were confirmed by the ophthalmological examination in 5.5% of cases. Retinal alterations were associated with age, disease duration and duration of the antimalarial therapy, but not to drug dose and comorbidities or lupus nephritis. This is the largest monocentric longitudinal study confirming the good safety profile of antimalarials in DLE and SLE patients. The main adverse events during the therapy were mild or moderate, but maculopathy—reported in a low percentage of patients—remains the main cause of treatment withdrawal.

Abstract
Introduction Due to a wide array of dermatologic manifestations, assessment of disease severity in cutaneous lupus erythematosus (CLE) remains challenging. Given a need for some standardization in this field, we conducted a worldwide questionnaire-based study among physicians experienced in CLE management. Aim We asked about CLE assessment, their prophylactic measures advised to patients, and treatment recommendations. Material and methods A total of 83 completed questionnaires were received. Participating physicians recommended assessing disease severity at each patient’s visit (39.1%), monthly (4.9%) or at least every third month (17.3%). Almost half of the responding physicians (47.0%) waited 2–3 months before identifying a specific treatment option as not effective. Results The vast part of the participants informed their patients about of the risks of sun exposure and advised adequate preventive measures. Smoking was less frequently a matter of discussion between physicians and their patients. Recommendations for the timing of CLE severity assessment likely depends on disease severity and the type of therapeutic intervention. Conclusions Proper patient education about effective prophylactic measures should be included during routine CLE patient consultations.

Abstract
Organic anion transporting polypeptides (OATP) 1B1 and OATP1B3 are important hepatic transporters that mediate the uptake of many clinically important drugs, including statins from the blood into the liver. Reduced transport function of OATP1B1 and OATP1B3 can lead to clinically relevant drug-drug interactions (DDIs). Considering the importance of OATP1B1 and OATP1B3 in hepatic drug disposition, substantial efforts have been given on evaluating OATP1B1/1B3-mediated DDIs in order to avoid unwanted adverse effects of drugs that are OATP substrates due to their altered pharmacokinetics. Growing evidences suggest that the transport function of OATP1B1 and OATP1B3 can be regulated at various levels such as genetic variation, transcriptional and post-translational regulation. The present review summarizes the up to date information on the regulation of OATP1B1 and OATP1B3 transport function at different levels with a focus on potential impact on OATP-mediated DDIs.

Abstract
Chloroquine (CQ) has been confirmed to exhibit antitumor effects on different types of cancer cell, but whether it exerts the same effect on acute promyelocytic leukemia (APL) cells remains to be confirmed. In the present study, the effects of various concentrations of CQ on the growth, apoptosis and cell cycle distribution of NB4 cells, as well as the potential mechanisms underlying these effects, were examined. The combined effect of CQ and arsenic trioxide (ATO) on the growth of NB4 cells was also determined. The results of the present study demonstrated that CQ treatment inhibited cell proliferation, and induced mitochondrial pathway apoptosis and S phase arrest in a dose-dependent manner by regulating apoptosis- and cell cycle-related proteins. CQ and ATO had a synergistic effect on the growth inhibition of NB4 cells, which may have been induced through the inhibition of autophagy. In conclusion, the results of the present study indicated that CQ exhibits a cytotoxic effect on NB4 cells and has a synergistic effect when combined with ATO, which thereby improves the curative effect of ATO on APL.

Abstract
Leprosy or Hansen's disease is a chronic infectious disease of the skin and nerves, caused by the intracellular bacilli Mycobacterium leprae. It is characterized by a spectrum of clinical forms depending on the host's immune response to M. leprae. Patients with tuberculoid (TT) leprosy have strong cell-mediated immunity (CMI) with elimination of the bacilli, whereas patients with lepromatous (LL) leprosy exhibit defective CMI to M. leprae. Despite advances in the understanding of the pathogenesis of leprosy and the development of new therapeutic strategies, there is a need for the identification of biomarkers which be used for early diagnosis and to discrimination between different forms of the disease, as prognostic markers. Here, we analyzed the serum levels of IL-1β, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-17A, IFN-γ and TNF in order to address the contribution of these cytokines in late phase of M. leprae infection, and the impact of multidrug therapy (MDT). Our results demonstrated that patients of LL group presented higher expression of serum levels of inflammatory cytokines before MDT, while TT patients presented a balance between inflammatory and regulatory cytokines. MDT changes the profile of serum cytokines in M. leprae infected patients, as evidenced by the cytokine network, especially in TT patients. LL patients displayed a multifaceted cytokine system characterized by strong connecting axes involving inflammatory/regulatory molecules, while TT patients showed low involvement of regulatory cytokines in network overall. Cytokines can be identified as good biomarkers of the impact of MDT on the immune system and the effectiveness of treatment.

Abstract
BACKGROUND Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus, which can cause scarring. Many drugs have been used to treat this disease and some (such as thalidomide, cyclophosphamide and azathioprine) are potentially toxic. This is an update of a Cochrane Review first published in 2000, and previously updated in 2009. We wanted to update the review to assess whether any new information was available to treat DLE, as we were still unsure of the effectiveness of available drugs and how to select the most appropriate treatment for an individual with DLE. OBJECTIVES To assess the effects of drugs for discoid lupus erythematosus. SEARCH METHODS We updated our searches of the following databases to 22 September 2016: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase and LILACS. We also searched five trials databases, and checked the reference lists of included studies for further references to relevant trials. Index Medicus (1956 to 1966) was handsearched and we approached authors for information about unpublished trials. SELECTION CRITERIA We included all randomised controlled trials (RCTs) of drugs to treat people with DLE in any population group and of either gender. Comparisons included any drug used for DLE against either another drug or against placebo cream. We excluded laser treatment, surgery, phototherapy, other forms of physical therapy, and photoprotection as we did not consider them drug treatments. DATA COLLECTION AND ANALYSIS At least two reviewers independently extracted data onto a data extraction sheet, resolving disagreements by discussion. We used standard methods to assess risk of bias, as expected by Cochrane. MAIN RESULTS Five trials involving 197 participants were included. Three new trials were included in this update. None of the five trials were of high quality.'Risk of bias' assessments identified potential sources of bias in each study. One study used an inappropriate randomisation method, and incomplete outcome data were a concern in another as 15 people did not complete the trial. We found most of the trials to be at low risk in terms of blinding, but three of the five did not describe allocation concealment.The included trials inadequately addressed the primary outcome measures of this review (percentage with complete resolution of skin lesions, percentage with clearing of erythema in at least 50% of lesions, and improvement in patient satisfaction/quality of life measures).One study of fluocinonide cream 0.05% (potent steroid) compared with hydrocortisone cream 1% (low-potency steroid) in 78 people reported complete resolution of skin lesions in 27% (10/37) of participants in the fluocinonide cream group and in 10% (4/41) in the hydrocortisone group, giving a 17% absolute benefit in favour of fluocinonide (risk ratio (RR) 2.77, 95% CI 0.95 to 8.08, 1 study, n = 78, low-quality evidence). The other primary outcome measures were not reported. Adverse events did not require discontinuation of the drug. Skin irritation occurred in three people using hydrocortisone, and one person developed acne. Burning occurred in two people using fluocinonide (moderate-quality evidence).A comparative trial of two oral agents, acitretin (50 mg daily) and hydroxychloroquine (400 mg daily), reported two of the outcomes of interest: complete resolution was seen in 13 of 28 participants (46%) on acitretin and 15 of 30 participants (50%) on hydoxychloroquine (RR 0.93, 95% CI 0.54 to 1.59, 1 study, n = 58, low-quality evidence). Clearing of erythema in at least 50% of lesions was reported in 10 of 24 participants (42%) on acitretin and 17 of 25 (68%) on hydroxychloroquine (RR 0.61, 95% CI 0.36 to 1.06, 1 study, n = 49, low-quality evidence). This comparison did not assess improvement in patient satisfaction/quality of life measures. Participants taking acitretin showed a small increase in serum triglyceride, not sufficient to require withdrawal of the drug. The main adverse effects were dry lips (93% of the acitretin group and 20% of the hydroxychloroquine group) and gastrointestinal disturbance (11% of the acitretin group and 17% of the hydroxychloroquine group). Four participants on acitretin withdrew due to gastrointestinal events or dry lips (moderate-quality evidence).One trial randomised 10 people with DLE to apply a calcineurin inhibitor, pimecrolimus 1% cream, or a potent steroid, betamethasone 17-valerate 0.1% cream, for eight weeks. The study reported none of the primary outcome measures, nor did it present data on adverse events.A trial of calcineurin inhibitors compared tacrolimus cream 0.1% with placebo (vehicle) over 12 weeks in 14 people, but reported none of our primary outcome measures. In the tacrolimus group, five participants complained of slight burning and itching, and for one participant, a herpes simplex infection was reactivated (moderate-quality evidence).Topical R-salbutamol 0.5% cream was compared with placebo (vehicle) over eight weeks in one trial of 37 people with DLE. There was a significant improvement in pain and itch in the salbutamol group at two, four, six, and eight weeks compared to placebo, but the trial did not record a formal measure of quality of life. None of the primary outcome measures were reported. Changes in erythema did not show benefit of salbutamol over placebo, but we could not obtain from the trial report the number of participants with clearing of erythema in at least 50% of lesions. There were 15 events in the placebo group (experienced by 12 participants) and 24 in the salbutamol group (experienced by nine participants). None of the adverse events were considered serious (moderate-quality evidence). AUTHORS' CONCLUSIONS Fluocinonide cream may be more effective than hydrocortisone in clearing DLE skin lesions. Hydroxychloroquine and acitretin appear to be of equal efficacy in terms of complete resolution, although adverse effects might be more frequent with acitretin, and clearing of erythema in at least 50% of lesions occurred less often in participants applying acitretin. Moderate-quality evidence found adverse events were minor on the whole. There is not enough reliable evidence about other drugs used to treat DLE. Overall, the quality of the trials and levels of uncertainty were such that there is a need for further trials of sufficient duration comparing, in particular, topical steroids with other agents.

Abstract
BACKGROUND The antimalarials (AMs) hydroxychloroquine (HCQ) and chloroquine (CQ) have demonstrated variable cutaneous response rates in cutaneous lupus erythematosus (CLE). OBJECTIVES We sought to assess the global cutaneous response rates to HCQ and CQ, with respect to CLE subtypes, based on previously published studies. METHODS We performed a systematic review and meta-analysis of studies published in MEDLINE, Embase and the Cochrane Library between 1965 and December 2015. The proportions of responders to AMs according to CLE subtypes were extracted from individual studies and pooled using random-effects or fixed models. The odds ratio (OR) was used as the measure of association to compare the response rates between CLE subtypes and AMs. RESULTS Among 1990 courses of treatment with AMs from 31 included studies, the overall response rate to AMs was 63% [95% confidence interval (CI) 55-70], with important statistical heterogeneity across the included studies. HCQ had a higher overall efficacy than CQ, but this was not significant (OR 1·48, 95% CI 0·98-2·23). The response rate to AMs was different between CLE subtypes, ranging from 31% (95% CI 20-44) for chilblain lupus to 91% (95% CI 87-93) for acute CLE. The response was significantly higher for acute CLE than for subacute CLE and intermittent CLE. In case of failure of monotherapy with AM, the combination of quinacrine with HCQ or CQ seemed effective, whereas too little data were available to assess the efficacy of the switch to another AM agent. CONCLUSIONS Wide discrepancies in cutaneous response to AMs are observed between CLE subtypes. A specific therapeutic approach considering CLE subtypes may improve CLE management.

Abstract
Cutaneous lupus erythematosus (CLE) is a rare inflammatory autoimmune disease with heterogeneous clinical manifestations. To date, no therapeutic agents have been licensed specifically for patients with this disease entity, and topical and systemic drugs are mostly used 'off-label'. The aim of the present guideline was to achieve a broad consensus on treatment strategies for patients with CLE by a European subcommittee, guided by the European Dermatology Forum (EDF) and supported by the European Academy of Dermatology and Venereology (EADV). In total, 16 European participants were included in this project and agreed on all recommendations. Topical corticosteroids remain the mainstay of treatment for localized CLE, and further topical agents, such as calcineurin inhibitors, are listed as alternative first-line or second-line topical therapeutic option. Antimalarials are recommended as first-line and long-term systemic treatment in all CLE patients with severe and/or widespread skin lesions, particularly in patients with a high risk of scarring and/or the development of systemic disease. In addition to antimalarials, systemic corticosteroids are recommended as first-line treatment in highly active and/or severe CLE. Second- and third-line systemic treatments include methotrexate, retinoids, dapsone and mycophenolate mofetil or mycophenolate acid, respectively. Thalidomide should only be used in selected therapy-refractory CLE patients, preferably in addition to antimalarials. Several new therapeutic options, such as B-cell- or interferon α-targeted agents, need to be further evaluated in clinical trials to assess their efficacy and safety in the treatment of patients with CLE.

Macrophage-Mediated Clofazimine Sequestration Is Accompanied by a Shift in Host Energy Metabolism. J Pharm Sci 2016; 106:1162-1174. [PMID: 28007559 DOI: 10.1016/j.xphs.2016.12.009] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2016] [Revised: 12/05/2016] [Accepted: 12/07/2016] [Indexed: 02/07/2023]
Abstract
Prolonged (8 weeks) oral administration of clofazimine results in a profound pharmacodynamic response-bioaccumulation in macrophages (including Kupffer cells) as intracellular crystal-like drug inclusions (CLDIs) with an associated increase in interleukin-1 receptor antagonist production. Notably, CLDI formation in Kupffer cells concomitantly occurs with the formation of macrophage-centric granulomas. Accordingly, we sought to understand the impact of these events on host metabolism using 1H-nuclear magnetic resonance metabolomics. Mice received a clofazimine or vehicle-enriched (sham) diet for at least 8 weeks. At 2 weeks, the antimicrobial activity of clofazimine was evident by changes in urine metabolites. From 2 to 8 weeks, there was a striking change in metabolite levels indicative of a reorientation of host energy metabolism paralleling the onset of CLDI and granuloma formation. This was evidenced by a progressive reduction in urine levels of metabolites involved in one-carbon metabolism with corresponding increases in whole blood, and changes in metabolites associated with lipid, nucleotide and amino acid metabolism, and glycolysis. Although clofazimine-fed mice ate more, they gained less weight than control mice. Together, these results indicate that macrophage sequestration of clofazimine as CLDIs and granuloma formation is accompanied by a profound metabolic disruption in energy homeostasis and one-carbon metabolism.

Abstract
Treatment of skin manifestations in systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and dermatomyositis (DM) is based on the results of only few randomized controlled trials. The first-line treatment for disfiguring and widespread cutaneous involvement in SLE is antimalarials, but some patients are therapy resistant. Recently, the monoclonal antibody belimumab was approved for SLE as an adjunct therapy for patients with autoantibody-positive disease who despite standard therapy show high disease activity, intolerance of other treatments, or an unacceptably high need for corticosteroids. However, a validated skin score has not been used to confirm the efficacy of belimumab on mucocutaneous manifestations. In SSc, another multi-systemic progressive disease, involvement of the lung, kidney, and the heart is frequently treated with corticosteroids and immunosuppressives, but therapeutic modalities for cutaneous lesions, such as skin sclerosis and digital ulcers, are limited. In the past years, treatment with the endothelin-receptor antagonist bosentan has been proven to reduce the occurrence of new digital ulcers in SSc patients but has no or limited effect on healing of digital ulcers. DM is an idiopathic autoimmune disease characterized by inflammation of the muscles and skin, which is treated with immunosuppressives. Corticosteroids are the first-line treatment for muscle involvement in DM, but skin lesions often flare by reduction or discontinuation. In summary, there is a high unmet need for new therapeutic strategies focusing on skin involvement in systemic autoimmune diseases. Therefore, innovative designs of randomized controlled trials with validated skin scores are warranted to develop new therapeutic strategies for patients with cutaneous manifestations.

Clofazimine (CFZ) is a poorly soluble antibiotic and anti-inflammatory drug indicated for the treatment of leprosy. In spite of its therapeutic value, CFZ therapy is accompanied by the formation of drug biocrystals that accumulate within resident tissue macrophages, without obvious toxicological manifestations. Therefore, to specifically elucidate the off-target consequences of drug bioaccumulation in macrophages, we compared the level of inflammasome activation in CFZ-accumulating organs (spleen, liver and lung) in mice after 2 and 8 weeks of CFZ treatment when the drug exists in soluble and insoluble (biocrystalline) forms, respectively. Surprisingly, the results showed a drastic reduction in caspase 1 and interleukin-1β (IL-1β) cleavage in the livers of mice treated with CFZ for 8 weeks (8-week-CFZ-treated mice) compared to 2-week-CFZ-treated and control mice, which was accompanied by a 3-fold increase in hepatic IL-1 receptor antagonist (IL-1RA) production and a 21-fold increase in serum IL-1RA levels. In the lung and spleen, IL-1β cleavage and tumor necrosis factor alpha expression were unaffected by soluble or biocrystal CFZ forms. Functionally, there was a drastic reduction of carrageenan- and lipopolysaccharide-induced inflammation in the footpads and lungs, respectively, of 8-week-CFZ-treated mice. This immunomodulatory activity of CFZ biocrystal accumulation was attributable to the upregulation of IL-1RA, since CFZ accumulation had minimal effect in IL-1RA knockout mice or 2-week-CFZ-treated mice. In conclusion, CFZ accumulation and biocrystal formation in resident tissue macrophages profoundly altered the host's immune system and prompted an IL-1RA-dependent, systemic anti-inflammatory response.

Abstract
Organic anion transporting polypeptide (OATP) 1B1 mediates the hepatic uptake of many drugs including lipid-lowering statins. Decreased OATP1B1 transport activity is often associated with increased systemic exposure of statins and statin-induced myopathy. Antimalarial drug chloroquine (CQ) is also used for long-term treatment of rheumatoid arthritis and systemic lupus erythematosus. CQ is lysosomotropic and inhibits protein degradation in lysosomes. The current studies were designed to determine the effects of CQ on OATP1B1 protein degradation, OATP1B1-mediated transport in OATP1B1-overexpressing cell line, and statin uptake in human sandwich-cultured hepatocytes (SCH). Treatment with lysosome inhibitor CQ increased OATP1B1 total protein levels in HEK293-OATP1B1 cells and in human SCH as determined by OATP1B1 immunoblot. In HEK293-FLAG-tagged OATP1B1 stable cell line, co-immunofluorescence staining indicated that intracellular FLAG-OATP1B1 is colocalized with lysosomal associated membrane glycoprotein (LAMP)-2, a marker protein of late endosome/lysosome. Enlarged LAMP-2-positive vacuoles with FLAG-OATP1B1 protein retained inside were readily detected in CQ-treated cells, consistent with blocking lysosomal degradation of OATP1B1 by CQ. In HEK293-OATP1B1 cells, without pre-incubation, CQ concentrations up to 100 μM did not affect OATP1B1-mediated [(3)H]E217G accumulation. However, pre-incubation with CQ at clinically relevant concentration(s) significantly decreased [(3)H]E217G and [(3)H]pitavastatin accumulation in HEK293-OATP1B1 cells and [(3)H]pitavastatin accumulation in human SCH. CQ pretreatment (25 μM, 2 h) resulted in ∼1.9-fold decrease in Vmax without affecting Km of OATP1B1-mediated [(3)H]E217G transport in HEK293-OATP1B1 cells. Pretreatment with monensin and bafilomycin A1, which also have lysosome inhibition activity, significantly decreased OATP1B1-mediated transport in HEK293-OATP1B1 cells. Pharmacoepidemiologic studies using data from the U.S. Food and Drug Administration Adverse Event Reporting System indicated that CQ plus pitavastatin, rosuvastatin, and pravastatin, which are minimally metabolized by the cytochrome P450 enzymes, led to higher myopathy risk than these statins alone. In summary, the present studies report novel findings that lysosome is involved in degradation of OATP1B1 protein and that pre-incubation with lysosomotropic drug CQ downregulates OATP1B1 transport activity. Our in vitro data in combination with pharmacoepidemiologic studies support that CQ has potential to cause OATP-mediated drug-drug interactions.

Abstract
Chloroquine (CQ) has been widely used in the treatment of malaria since the 1950s, though toxicity and resistance is increasingly limiting its use in the clinic. More recently, CQ is also becoming recognized as an important therapeutic compound for the treatment of autoimmune disorders and has shown activity as an anticancer agent. However, the full extent of CQ pharmacology in humans is still unclear. Herein, we demonstrate that the lysosomal protein saposin B (sapB), critical for select lipid degradation, binds CQ with implications for both CQ function and toxicity. Using isothermal titration calorimetry (ITC) and fluorescence quenching experiments, CQ was shown to bind to the dimeric form of sapB at both pH 5.5 and pH 7.4 with an average binding affinity of 2.3×10(4) m(-1). X-ray crystallography confirmed this, and the first complete crystal structure of sapB with a bound small molecule (CQ) is reported. The results suggest that sapB might play a role in mitigating CQ-based toxicity and that sapB might itself be overwhelmed by CQ causing impaired lipid degradation.

Abstract
Clofazimine (CFZ) is an FDA-approved leprostatic and anti-inflammatory drug that massively accumulates in macrophages, forming insoluble, intracellular crystal-like drug inclusions (CLDIs) during long-term oral dosing. Interestingly, when added to cells in vitro, soluble CFZ is cytotoxic because it depolarizes mitochondria and induces apoptosis. Accordingly, we hypothesized that, in vivo, macrophages detoxify CFZ by sequestering it in CLDIs. To test this hypothesis, CLDIs of CFZ-treated mice were biochemically isolated and then incubated with macrophages in vitro. The cell biological effects of phagocytosed CLDIs were compared to those of soluble CFZ. Unlike soluble CFZ, phagocytosis of CLDIs did not lead to mitochondrial destabilization or apoptosis. Rather, CLDIs altered immune signaling response pathways downstream of Toll-like receptor (TLR) ligation, leading to enhanced interleukin-1 receptor antagonist (IL-1RA) production, dampened NF-κB activation and tissue necrosis factor alpha (TNFα) production, and ultimately decreased TLR expression levels. In aggregate, our results constitute evidence that macrophages detoxify soluble CFZ by sequestering it in a biocompatible, insoluble form. The altered cellular response to TLR ligation suggests that CLDI formation may also underlie CFZ's anti-inflammatory activity.

Abstract
Systemic Lupus Erythematosus is a chronic inflammatory disease with multifactorial etiology. Although clinical manifestations are varied, the skin is an important target-organ, which contributes to the inclusion of skin lesions in 4 out of the 17 new criteria for the diagnosis of the disease, according to the Systemic Lupus International Collaborating Clinics. The cutaneous manifestations of lupus are pleomorphic. Depending on their clinical characteristics, they can be classified into Acute Cutaneous Lupus Erythematosus, Subacute Cutaneous Lupus Erythematosus, Chronic Cutaneous Lupus Erythematosus and Intermittent Cutaneous Lupus Erythematosus. Treatment is based on preventive measures, reversal of inflammation, prevention of damage to target organs and relief of adverse events due to pharmacological therapy. The most commonly used treatment options are topical, systemic and surgical treatment, as well as phototherapy. The correct handling of the cases depends on a careful evaluation of the morphology of the lesions and the patient's general status, always taking into consideration not only the benefits but also the side effects of each therapeutic proposal.

Abstract
For more than two decades, chloroquine (CQ) was largely and deliberately used as first choice drug for malaria treatment. However, worldwide increasing cases of resistant strains of Plasmodium have hampered its use. Nevertheless, CQ has recently been tested as adjunct therapy in several inflammatory situations, such as rheumatoid arthritis and transplantation procedures, presenting intriguing and promising results. In this review, we discuss recent findings and CQ mechanisms of action vis-à-vis its use as a broad adjunct therapy.

Abstract
Cutaneous lupus erythematosus (CLE) encompasses a wide range of dermatologic manifestations, which may or may not be associated with the development of systemic disease. Cutaneous lupus is divided into several sub-types, including acute CLE (ACLE), sub-acute CLE (SCLE) and chronic CLE (CCLE). CCLE includes discoid lupus erythematosus (DLE), LE profundus (LEP), chilblain cutaneous lupus and lupus tumidus. The diagnosis of these diseases requires proper classification of the sub-type, through a combination of physical examination, laboratory studies, histology, antibody serology and occasionally direct immunofluorescence, while ensuring to exclude systemic disease. The treatment of cutaneous lupus consists of patient education on proper sun protection along with appropriate topical and systemic agents. Systemic agents are indicated in cases of widespread, scarring or treatment-refractory disease. In this chapter, we discuss issues in classification and diagnosis of the various sub-types of CLE, as well as provide an update on therapeutic management.

Abstract
Clofazimine, a lipophilic riminophenazine antibiotic, possesses both antimycobacterial and anti-inflammatory activities. However, its efficacy has been demonstrated only in the treatment of leprosy, not in human tuberculosis, despite the fact that this agent is impressively active in vitro against multidrug-resistant strains of Mycobacterium tuberculosis. Recent insights into novel targets and mechanisms of antimicrobial and anti-inflammatory activity coupled with the acquisition of innovative drug delivery technologies have, however, rekindled interest in clofazimine as a potential therapy for multidrug- and extensively multidrug-resistant tuberculosis in particular, as well as several autoimmune diseases. The primary objective of this review is to critically evaluate these recent developments and to assess their potential impact on improving the therapeutic efficacy and versatility of clofazimine.

Abstract
Cutaneous lupus erythematosus (CLE) is an autoimmune inflammatory skin disease seen in patients with or without systemic lupus erythematosus. The management of CLE includes treatment and prevention of lesions as well as routine assessment for systemic disease. Treatment options include topical and systemic therapies. Topical therapies include corticosteroids and calcineurin inhibitors. Systemic therapies generally fall under one of three categories: antimalarials, immunomodulators (eg, dapsone and thalidomide), and immunosuppressives (eg, methotrexate and mycophenolate). Evidence for the treatment of CLE has been limited by few prospective studies and the lack of a validated outcome measure (until recently). There is good evidence to support the use of topical steroids and calcineurin inhibitors, although most of these trials have not used placebo or vehicle controls. There have been no randomized, placebo-controlled trials evaluating systemic therapies in the treatment of CLE.

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
The global tuberculosis crisis urgently demands new, efficacious, orally available drugs with the potential to shorten and simplify the long and complex treatments for drug-sensitive and drug-resistant disease. Clofazimine, a riminophenazine used for many years to treat leprosy, demonstrates efficacy in animal models of tuberculosis via a novel mode of action. However, clofazimine's physicochemical and pharmacokinetic properties contribute to side effects that limit its use; in particular, an extremely long half-life and propensity for tissue accumulation together with clofazimine's dye properties leads to unwelcome skin discoloration. We recently conducted a systematic structure-activity study of more than 500 riminophenazine analogs for anti-Mycobacterium tuberculosis activity. We describe here the characteristics of 12 prioritized compounds in more detail. The new riminophenazine analogs demonstrated enhanced in vitro activity compared to clofazimine against replicating M. tuberculosis H37Rv, as well as panels of drug-sensitive and drug-resistant clinical isolates. The new compounds demonstrate at least equivalent activity compared to clofazimine against intracellular M. tuberculosis and, in addition, most of them were active against nonreplicating M. tuberculosis. Eleven of these more water-soluble riminophenazine analogs possess shorter half-lives than clofazimine when dosed orally to mice, suggesting that they may accumulate less. Most importantly, the nine compounds that progressed to efficacy testing demonstrated inhibition of bacterial growth in the lungs that is superior to the activity of an equivalent dose of clofazimine when administered orally for 20 days in a murine model of acute tuberculosis. The efficacy of these compounds, along with their decreased potential for accumulation and therefore perhaps also for tissue discoloration, warrants further study.

PARTICIPANTS A total of 128 patients with CLE who presented from January 2007 to July 2010 and had at least 2 visits with activity scores. INTERVENTION Administration of antimalarial agents. MAIN OUTCOME MEASURES Response was defined by a 4-point or 20% decrease in activity score. Response to initiation was determined by the difference between the scores before treatment and at the first visit at least 2 months after treatment. Response to continuation was determined by the difference between the scores at the first visit and the most recent visit while undergoing treatment. RESULTS Of 11 patients who initiated treatment with hydroxychloroquine, 55% were responders (n = 6), showing a decrease in median (interquartile range [IQR]) activity score from 8.0 (3.5-13.0) to 3.0 (1.8-7.3) (P = .03). Of 15 patients for whom hydroxychloroquine failed, 67% were responders to initiation of hydroxychloroquine-quinacrine therapy (n = 10), showing a decrease in median (IQR) activity score from 6.0 (4.8-8.3) to 3.0 (0.75-5.0) (P = .004). Nine of 21 patients who continued hydroxychloroquine treatment (43%), and 9 of 21 patients who continued hydroxychloroquine-quinacrine (43%) were responders, showing a decrease in median (IQR) activity score from 6.0 (1.5-9.5) to 1.0 (0.0-4.5) (P = .01) and 8.5 (4.25-17.5) to 5.0 (0.5-11.5) (P = .01), respectively. CONCLUSIONS The use of quinacrine with hydroxychloroquine is associated with response in patients for whom hydroxychloroquine monotherapy fails. Further reduction in disease activity can be associated with continuation of treatment with antimalarial agents.

Abstract
In patients with cutaneous lupus erythematosus (CLE) and mild skin involvement, local therapy consisting of topically applied pharmacological agents, e.g., topical/intralesional steroids, may be sufficient. Recent reports have also shown efficacy of topical calcineurin inhibitors in patients with CLE, particularly on the face. Special attention receives consistent sun protection through photoresistant clothing and application of light-shielding substances with highly potent chemical or physical UVA- and UVB-protective filters. These substances should be applied in sufficient amount (ca. 2 mg/cm(2)) at least 20-30 minutes before sun exposure in order to avoid induction and exacerbation of cutaneous lesions. The mainstay of treatment for disfiguring and widespread skin manifestations in patients with CLE, irrespective of the subtype of the disease, is antimalarial agents. Our understanding of the use of combinations of antimalarials and proper dosing according to the ideal bodyweight limits problems with toxicity. Further therapies, such as methotrexate, or retinoids, dapsone, mycophenolate mofetil, and thalidomide in selected cases, can be helpful for patients with resistant disease; however, side effects need to be taken into consideration. Recent advances in biotechnology resulted in the development of novel systemic agents, but randomized controlled trials are necessary for the approval of new therapeutic strategies in CLE.
