Abstract
BACKGROUND Acne vulgaris commonly affects adults, adolescents, and preadolescents aged 9 years or older. OBJECTIVE The objective of this study was to provide evidence-based recommendations for the management of acne. METHODS A work group conducted a systematic review and applied the Grading of Recommendations, Assessment, Development, and Evaluation approach for assessing the certainty of evidence and formulating and grading recommendations. RESULTS This guideline presents 18 evidence-based recommendations and 5 good practice statements. Strong recommendations are made for benzoyl peroxide, topical retinoids, topical antibiotics, and oral doxycycline. Oral isotretinoin is strongly recommended for acne that is severe, causing psychosocial burden or scarring, or failing standard oral or topical therapy. Conditional recommendations are made for topical clascoterone, salicylic acid, and azelaic acid, as well as for oral minocycline, sarecycline, combined oral contraceptive pills, and spironolactone. Combining topical therapies with multiple mechanisms of action, limiting systemic antibiotic use, combining systemic antibiotics with topical therapies, and adding intralesional corticosteroid injections for larger acne lesions are recommended as good practice statements. LIMITATIONS Analysis is based on the best available evidence at the time of the systematic review. CONCLUSIONS These guidelines provide evidence-based recommendations for the management of acne vulgaris.

Abstract
Conditions referred to as 'male sexual dysfunctions' usually include erectile dysfunction, ejaculatory disorders and male hypogonadism. However, some less common male sexual disorders exist, which are under-recognized and under-treated, leading to considerable morbidity, with adverse effects on individuals' sexual health and relationships. Such conditions include post-finasteride syndrome, restless genital syndrome, post-orgasmic illness syndrome, post-selective serotonin reuptake inhibitor (SSRI) sexual dysfunction, hard-flaccid syndrome, sleep-related painful erections and post-retinoid sexual dysfunction. Information about these disorders usually originates from case-control trials or small case series; thus, the published literature is scarce. As the aetiology of these diseases has not been fully elucidated, the optimal investigational work-up and therapy are not well defined, and the available options cannot, therefore, adequately address patients' sexual problems and implement appropriate treatment. Thus, larger-scale studies - including prospective trials and comprehensive case registries - are crucial to better understand the aetiology, prevalence and clinical characteristics of these conditions. Furthermore, collaborative efforts among researchers, health-care professionals and patient advocacy groups will be essential in order to develop evidence-based guidelines and novel therapeutic approaches that can effectively address these disorders. By advancing our understanding and refining treatment strategies, we can strive towards improving the quality of life and fostering healthier sexual relationships for individuals suffering from these rare sexual disorders.

Abstract
Acne vulgaris is one of the most common skin disorders worldwide. It typically affects skin areas with a high density of sebaceous glands such as the face, upper arms, chest, and/or back. Historically, the majority of research efforts have focused on facial acne vulgaris, even though approximately half of patients with facial lesions demonstrate truncal involvement. Truncal acne vulgaris is challenging to treat and poses a significant psychosocial burden on patients. Despite these characteristics, studies specifically examining truncal acne vulgaris are limited, with treatment guidelines largely derived from facial protocols. Therefore, truncal acne remains an understudied clinical problem. Here, we provide a clinically focused review on the epidemiology, evaluation, and available treatment options for truncal acne vulgaris. In doing so, we highlight knowledge gaps with the goal of spurring further investigation into the management of truncal acne vulgaris.

Abstract
Background Acne vulgaris (AV) is a chronic inflammatory disease that affects the pilosebaceous unit. Leptin (LEP) gene polymorphisms is associated with higher risk of multiple disorders. Insulin-like growth factor-1 (IGF-1) exerts comedogenic effect by stimulating the sebaceous glands. Isotretinoin is an effective oral therapy for AV with many side effects including hyperlipidemia and increased serum levels of liver enzymes. Purpose To evaluate the impact of LEP gene rs7799039 polymorphism in acne patients' clinical response lipid profile and liver enzymes following 6 months oral isotretinoin therapy in Egyptian AV patients. Methods One hundred eligible AV patients received 0.5 mg/kg oral isotretinoin for 6 months. Patients' demographics and clinical data were obtained. Body mass index (BMI), lipid profile, liver enzymes and IGF-1 were measured at baseline and after 6 months of therapy. Genotyping was done for LEP gene rs 7799039. Results Six month administration of oral isotretinoin in Egyptian AV patients is associated with significantly elevated aspartate transaminase (AST) in CC and AC genotypes (P<0.001). Significant alanine aminotransferase (ALT) elevation was observed in CC, AC and AA genotypes (P <0.001, 0.004, 0.002, respectively). Total cholesterol (TC), triglycerides (TG) and low density lipoprotein (LDL) were elevated significantly P<0.001) in the three genotypes. IGF-1 was decreased significantly in CC and AC genotypes (P<0.001). CC genotype is associated with highest response (P<0.001). Conclusion LEP rs7799039 gene had an impact on the clinical response, lipid profile and liver enzymes in AV patients treated with oral isotretinoin. LEP rs7799039 CC genotype is predicted to be the treatment candidate for 6 month oral isotretinoin.

Abstract
Acne is associated with depression and anxiety; however, the relationship between acne and suicide is still unclear. This study is aimed to evaluate the association between acne and suicide by conducting a meta-analysis. Studies were identified by electronic searches of the PubMed and EMBASE databases from their inception through Jan 10, 2020. Two authors separately assessed the quality and extracted data from the selected studies. When the heterogeneity was significant, we used a random-effects model to calculate overall pooled risk estimates.Five studies involving a total of 2,276,798 participants were finally included in the meta-analysis; 52,075 participants had acne. Suicide was positively associated with acne in the overall analysis (odds ratio (OR) 1.50, 95% confidence interval (95% CI): 1.09-2.06, P = .004, I2 = 74.1%). Subgroup analyses were performed for suicidal behavior groups (P = .002, I2 = 80.4%), suicidal ideation or thoughts groups (P = .849, I2 = 0.0%), International Classification of Diseases version 9 (ICD-9) groups (P = .137, I2 = 49.6%), non-ICD-9 groups (P = .950, I2 = 0.0%), American groups (P = .311, I2 = 2.4%), and non-American groups (P = .943, I2 = 0.0%). Sensitivity analyses indicated flawed results. No publication bias was detected.Acne may significantly increase suicide risk. Clinicians should actively treat acne and consider suicide screening. Further international studies with high-quality analyses are needed as more data are published.Ethical approval and patient consent are not required because this study is a literature-based study.

Abstract
Previous approaches to acne management have focused on the four main factors implicated in acne, namely, androgen-mediated sebogenesis (considered integral to acne), hyperkeratinization, colonization with Cutibacterium acnes, and inflammation related to both innate and adaptive mechanisms. Recent advances have facilitated potential novel approaches to acne management, as the pathophysiology and the immunological aspects related to acne and wound healing have evolved. Particular targets that have been shown to be closely involved in acne pathophysiology and wound healing include interleukin (IL)-1β, IL-17, IL-23, and tumor necrosis factor alpha (TNFα). Biological antibodies targeting IL-1β, IL-17, IL-23, and TNFα could provide novel approaches for treating severe acne and related disorders. Acne is primarily a disease associated with sebogenesis. Monosaturated free acids are important components. Insulin growth factor 1 (IGF-1) promotes the proliferation and differentiation of sebocytes and IL-1β. Research into the microbiome may also provide insights into potential future therapeutic options for acne. Scars, both atrophic and hypertrophic, are common sequelae to acne. Risk factors associated with the development of acne scars include genetic, systemic, local, and lifestyle factors. Pro-inflammatory cytokines have been shown to play a crucial role in the development of acne-induced hypertrophic scars. Treatment for extensive inflammatory keloid scarring is limited. Surgery and postoperative radiotherapy are two possible options. Transforming growth factor-β (TGFβ), IL-6, matrix metalloproteinase (MMP), IGF-1, and B cells are found in keloid or hypertrophic scar tissues. Biological antibodies targeting these cytokines may be a potential strategy for the prevention and treatment of this type of scar in the future. Future treatment for acne should embrace approaches that target the main etiological factors of acne. In particular, specific emphasis on aggressive treatment in the acute inflammatory phase to reduce the likelihood of scarring and other clinical sequelae, such as pigmentary changes would be highly desirable. Treatment for established acne-induced sequelae should also be considered.

Abstract
Importance Acne is a common dermatologic condition and significantly affects psychosocial health and quality of life. An international task force recommended routine use of quality-of-life measures for clinic visits associated with acne management, but this has yet to translate into clinical practice. Objective To assess mean Skindex-16 scores over time among patients with moderate to severe acne receiving isotretinoin treatment. Design, Setting, and Participants A longitudinal, retrospective case series study of Skindex-16 data collected at monthly visits from 57 consecutive patients with acne receiving isotretinoin; data were collected and evaluated between November 23, 2016, and January 22, 2019. Continuous variables were compared using quantile regression. Multivariable linear mixed models evaluated mean (95% CI) score trajectory over time. Main Outcomes and Measure Skindex-16 scores, including normalized scores for the emotional, symptomatic, and functional aspects of having skin disease as well as an overall score. Results Fifty-seven patients (31 [54.4 %] males, with median [interquartile range] age of 17.2 [15.9-18.1] years) in this case series study completed the Skindex-16 at baseline and at least once during follow-up. Baseline Skindex-16 scores were similar by sex but worse with increasing age. Emotional impact was more bothersome to patients with acne requiring isotretinoin treatment than either symptoms or functioning. Improvements of greater than 50% in overall and Emotional domain scores were seen by month 2 of receiving isotretinoin treatment (eg, overall scores decreased from 39.4 to 17.5 by month 2; a decrease of 22.0; P < .001). Qualitatively, Skindex-16 scores reached their nadir between months 3 and 5; at month 4, overall Skindex-16 scores showed a 4.4-fold improvement (from 39.4 at baseline to 8.9; P < .001) and Emotional domain scores showed a 4.8-fold improvement (from 57.7 at baseline to 11.9; P < .001). Conclusions and Relevance The findings of this case series suggest that patients receiving isotretinoin treatment achieve greater than a 50% improvement in quality of life by month 2 and can expect approximately 4-fold to 5-fold improvements from baseline with a full course of isotretinoin. This study shows the potential of routine administration of quality of life measures to assess patient care in dermatology.

An Bras Dermatol 2020; 95 Suppl 1:19-38. [PMID: 33036809 PMCID: PMC7772596 DOI: 10.1016/j.abd.2020.09.001] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Accepted: 05/11/2020] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Isotretinoin is a synthetic retinoid, derived from vitamin A, with multiple mechanisms of action and highly effective in the treatment of acne, despite common adverse events, manageable and dose-dependent. Dose-independent teratogenicity is the most serious. Therefore, off-label prescriptions require strict criteria. OBJECTIVE To communicate the experience and recommendation of Brazilian dermatologists on oral use of the drug in dermatology. METHODS Eight experts from five universities were appointed by the Brazilian Society of Dermatology to develop a consensus on indications for this drug. Through the adapted DELPHI methodology, relevant elements were listed and an extensive analysis of the literature was carried out. The consensus was defined with the approval of at least 70% of the experts. RESULTS With 100% approval from the authors, there was no doubt about the efficacy of oral isotretinoin in the treatment of acne, including as an adjunct in the correction of scars. Common and manageable common adverse events are mucocutaneous in nature. Others, such as growth retardation, abnormal healing, depression, and inflammatory bowel disease have been thoroughly investigated, and there is no evidence of a causal association; they are rare, individual, and should not contraindicate the use of the drug. Regarding unapproved indications, it may represent an option in cases of refractory rosacea, severe seborrheic dermatitis, stabilization of field cancerization with advanced photoaging and, although incipient, frontal fibrosing alopecia. For keratinization disorders, acitretin performs better. In the opinion of the authors, indications for purely esthetic purposes or oil control are not recommended, particularly for women of childbearing age. CONCLUSIONS Approved and non-approved indications, efficacy and adverse effects of oral isotretinoin in dermatology were presented and critically evaluated.

Abstract
Congenital heart disease (CHD) has many forms and a wide range of causes. Clinically, it is important to understand the causes. This allows estimation of recurrence rate, guides treatment options, and may also be used to formulate public health advice to reduce the population prevalence of CHD. The recent advent of sophisticated genetic and genomic methods has led to the identification of more than 100 genes associated with CHD. However, despite these great strides, to date only one-third of CHD cases have been shown to have a simple genetic cause. This is because CHD can also be caused by oligogenic factors, environmental factors, and/or gene-environment interaction. Although solid evidence for environmental causes of CHD have been available for almost 80 years, it is only very recently that the molecular mechanisms for these risk factors have begun to be investigated. In this review, we describe the most important environmental CHD risk factors, and what is known about how they cause CHD.

[PMID: 31926435 DOI: 10.1016/j.envint.2020.105464] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 12/13/2019] [Accepted: 01/02/2020] [Indexed: 06/10/2023]
Abstract
In animals, retinoic acids (RAs), one of the main derivatives of vitamin A, are crucial for a variety of physiological processes. RAs, including all-trans-RA, 9-cis-RA, 13-cis-RA, and their corresponding metabolites (i.e., all-trans-4-oxo-RA, 9-cis-4-oxo-RA and 13-cis-4-oxo-RA) can be excreted through urination from humans and animals. Sewage treatment plants (STPs) are a significant source of RAs and 4-oxo-RAs into aquatic environments. RAs and 4-oxo-RAs can be identified and quantified by use of liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). RAs and 4-oxo-RAs have been reported in various environmental matrices including rivers, lakes, reservoirs and coastal marine environments as well as in sewage effluents discharged from STPs. Greater concentrations of RAs and 4-oxo-RAs have been observed during blooms of cyanobacteria and microalgae, suggesting that cyanobacteria and microalgae are natural sources of RAs and 4-oxo-RAs in aquatic environments. These potential sources of RAs and 4-oxo-RAs raise concerns about their concentrations and risks in aquatic environments because excessive intake of these chemicals can result in abnormal morphological development in animals. Teratogenic effects were observed in amphibians, fish embryos, gastropods, mammals and birds when exposed to RAs. This review summarizes sources, concentrations, adverse effects and ecological risks of RAs and 4-oxo-RAs in aquatic environments. An interim, predicted no-effect concentration (PNEC) of RAs (in terms of at-RA) for freshwater environments was determined to be 3.93 ng/L at-RA equivalents. Based on limited data on concentrations of RAs in freshwater ecosystems, their hazard quotients were found to range from zero to 16.41, depending on the environmental conditions of receiving waters. Ecological risks of RAs in marine environments are yet to be explored due to the paucity of data related to both their concentrations in marine environment and toxic potencies to marine species. This review updates current knowledge of RAs and 4-oxo-RAs in aquatic environments and calls for more studies on their concentrations and fate in aquatic environments, especially estuarine and coastal marine environments with a view to enabling a comprehensive assessment of their ecological risks around the globe.

Abstract
Background. According to European and RF clinical guidelines, only the systemic use of isotretinoin in severe acne has a high level of evidence. However, this therapy is frequently associated with the development of retinoid dermatitis, the prevention and correction of which requires the application of emollients. Aim. To evaluate the efficacy and tolerability of the Perfectoin cream during treatment and prevention of retinoid dermatitis in patients with severe acne receiving systemic treatment with isotretinoin.Materials and methods. Two groups of patients each comprising 38 people with moderate, severe and resistant to standard therapy forms of acne were observed. Each group included 22 patients with retinoic dermatitis manifestations and 16 without such symptoms. The patients in the main and comparison groups were prescribed the Perfectoin cream and the dexpanthenol cream, respectively. Control of the skin condition was performed prior to the study and following 1, 3 and 6 months of therapy. Assessment parameters were the main symptoms of retinoid dermatitis (erythema, lichenification, excoriation, itching, feeling of dryness/tightness of the skin), indicators of the hydration of the horny layer of the epidermis and the transepidermal loss of moisture, as well as the dermatology life quality index.Results. The study has shown that the Perfectoin cream in patients with acne receiving isotretinoin therapy helps to restore skin hydration and leads to a rapid regression of the main dermatological symptoms of retinoid dermatitis, thus improving the overall quality of patients’ life.

Abstract
Abstract
Background
Isotretinoin is the only effective treatment for severe acne. An isotretinoin-related suicide risk is still debated and under scrutiny by regulatory agencies. Our objectives were: to assess the risk of suicide attempt before, during and after isotretinoin treatment; to detect any potential triggering effect of isotretinoin initiation on suicide attempt.
Methods
We implemented a cohort and nested case-time-control study of subjects treated with oral isotretinoin (course or initiation) aged 10–50 years, using the Nationwide French Health Insurance data (2009–2016). The main outcome was hospitalized suicide attempt. Standardized incidence ratios for hospitalized suicide attempts were calculated before, during and after isotretinoin treatment. The number of isotretinoin initiations was compared in risk and control periods of 2 months using a case-time-control analysis.
Results
In all, 443 814 patients (median age 20.0 years; interquartile range 17.0–27.0 years) were exposed to isotretinoin, amounting to 244 154 person-years, with a marked seasonality for treatment initiation. Compared with the French general population, the occurrence of suicide attempts under isotretinoin treatment was markedly lower, with a standardized incidence ratio of 0.6 [95% confidence interval (CI) = 0.53–0.67]; the same applied, to a lesser extent, before and after isotretinoin treatment. In the case-time-control analysis, among cases of suicide attempt, 108 and 127 isotretinoin initiations were observed in the risk and control periods respectively (i.e. 0–2 months and 2–4 months before the date of suicide attempt). The comparison with the 1199 and 1253 initiations observed among matched controls in the same two periods yielded a case-time-control odds ratio of 0.89 (95% CI = 0.68–1.16). A sensitivity analysis using three-month periods and a complementary analysis adding completed suicides for case definition showed consistent results.
Conclusion
Compared with the general population, a lower risk of suicide attempt was observed among patients exposed to isotretinoin and there was no evidence for a triggering effect of isotretinoin initiation on suicide attempt. A selection of patients at lower risk for suicidal behaviour and appropriate treatment management could explain these findings. Risk management plans should therefore be maintained.

Abstract
BACKGROUND Acne vulgaris, a chronic inflammatory disease of the pilosebaceous unit associated with socialisation and mental health problems, may affect more than 80% of teenagers. Isotretinoin is the only drug that targets all primary causal factors of acne; however, it may cause adverse effects. OBJECTIVES To assess efficacy and safety of oral isotretinoin for acne vulgaris. SEARCH METHODS We searched the following databases up to July 2017: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO and LILACS. We updated this search in March 2018, but these results have not yet been incorporated in the review. We also searched five trial registries, checked the reference lists of retrieved studies for further references to relevant trials, and handsearched dermatology conference proceedings. A separate search for adverse effects of oral isotretinoin was undertaken in MEDLINE and Embase up to September 2013. SELECTION CRITERIA Randomised clinical trials (RCTs) of oral isotretinoin in participants with clinically diagnosed acne compared against placebo, any other systemic or topical active therapy, and itself in different formulation, doses, regimens, or course duration. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included 31 RCTs, involving 3836 participants (12 to 55 years) with mild to severe acne. There were twice as many male participants as females.Most studies were undertaken in Asia, Europe, and North America. Outcomes were generally measured between eight to 32 weeks (mean 19.7 weeks) of therapy.Assessed comparisons included oral isotretinoin versus placebo or other treatments such as antibiotics. In addition, different doses, regimens, or formulations of oral isotretinoin were assessed, as well as oral isotretinoin with the addition of topical agents.Pharmaceutical companies funded 12 included trials. All, except three studies, had high risk of bias in at least one domain.Oral isotretinoin compared with oral antibiotics plus topical agentsThese studies included participants with moderate or severe acne and assessed outcomes immediately after 20 to 24 weeks of treatment (short-term). Three studies (400 participants) showed isotretinoin makes no difference in terms of decreasing trial investigator-assessed inflammatory lesion count (RR 1.01 95% CI 0.96 to 1.06), with only one serious adverse effect found, which was Stevens-Johnson syndrome in the isotretinoin group (RR 3.00, 95% CI 0.12 to 72.98). However, we are uncertain about these results as they were based on very low-quality evidence.Isotretinoin may slightly improve (by 15%) acne severity, assessed by physician's global evaluation (RR 1.15, 95% CI 1.00 to 1.32; 351 participants; 2 studies), but resulted in more less serious adverse effects (67% higher risk) (RR 1.67, 95% CI 1.42 to 1.98; 351 participants; 2 studies), such as dry lips/skin, cheilitis, vomiting, nausea (both outcomes, low-quality evidence).Different doses/therapeutic regimens of oral isotretinoinFor our primary efficacy outcome, we found three RCTs, but heterogeneity precluded meta-analysis. One study (154 participants) reported 79%, 80% and 84% decrease in total inflammatory lesion count after 20 weeks of 0.05, 0.1, or 0.2 mg/kg/d of oral isotretinoin for severe acne (low-quality evidence). Another trial (150 participants, severe acne) compared 0.1, 0.5, and 1 mg/kg/d oral isotretinoin for 20 weeks and, respectively, 58%, 80% and 90% of participants achieved 95% decrease in total inflammatory lesion count. One RCT, of participants with moderate acne, compared isotretinoin for 24 weeks at (a) continuous low dose (0.25 to 0.4 mg/kg/day), (b) continuous conventional dose (0.5 to 0.7 mg/kg/day), and (c) intermittent regimen (0.5 to 0.7 mg/kg/day, for one week in a month). Continuous low dose (MD 3.72 lesions; 95% CI 2.13 to 5.31; 40 participants; one study) and conventional dose (MD 3.87 lesions; 95% CI 2.31 to 5.43; 40 participants; one study) had a greater decrease in inflammatory lesion counts compared to intermittent treatment (all outcomes, low-quality evidence).Fourteen RCTs (906 participants, severe and moderate acne) reported that no serious adverse events were observed when comparing different doses/therapeutic regimens of oral isotretinoin during treatment (from 12 to 32 weeks) or follow-up after end of treatment (up to 48 weeks). Thirteen RCTs (858 participants) analysed frequency of less serious adverse effects, which included skin dryness, hair loss, and itching, but heterogeneity regarding the assessment of the outcome precluded data pooling; hence, there is uncertainty about the results (low- to very-low quality evidence, where assessed).Improvement in acne severity, assessed by physician's global evaluation, was not measured for this comparison.None of the included RCTs reported birth defects. AUTHORS' CONCLUSIONS Evidence was low-quality for most assessed outcomes.We are unsure if isotretinoin improves acne severity compared with standard oral antibiotic and topical treatment when assessed by a decrease in total inflammatory lesion count, but it may slightly improve physician-assessed acne severity. Only one serious adverse event was reported in the isotretinoin group, which means we are uncertain of the risk of serious adverse effects; however, isotretinoin may result in more minor adverse effects.Heterogeneity in the studies comparing different regimens, doses, or formulations of oral isotretinoin meant we were unable to undertake meta-analysis. Daily treatment may be more effective than treatment for one week each month. None of the studies in this comparison reported serious adverse effects, or measured improvement in acne severity assessed by physician's global evaluation. We are uncertain if there is a difference in number of minor adverse effects, such as skin dryness, between doses/regimens.Evidence quality was lessened due to imprecision and attrition bias. Further studies should ensure clearly reported long- and short-term standardised assessment of improvement in total inflammatory lesion counts, participant-reported outcomes, and full safety accounts. Oral isotretinoin for acne that has not responded to oral antibiotics plus topical agents needs further assessment, as well as different dose/regimens of oral isotretinoin in acne of all severities.

Abstract
This review focuses on the treatment options for adult female patients with acne. Acne in adult female patients may start during adolescence and persist or have an onset in adulthood. Acne has various psychosocial effects that impact patients’ quality of life. Treatment of acne in adult women specifically has its challenges due to the considerations of patient preferences, pregnancy, and lactation. Treatments vary widely and treatment should be tailored specifically for each individual woman. We review conventional therapies with high levels of evidence, additional treatments with support from cohort studies and case reports, complementary and/or alternative therapies, and new agents under development for the treatment of patients with acne.

Abstract
Despite many years of clinical use of isotretinoin, a comprehensive review of evidence for isotretinoin therapy in patients with acne is lacking. We searched MEDLINE, Embase, Cochrane Central, relevant web pages and bibliographies for randomized controlled trials in acne evaluating isotretinoin vs. control (placebo or other therapy). Data were extracted and summarized descriptively. Eleven trials were identified (total 760 patients randomized), containing mostly men. Mean treatment ages ranged from 18 to 47·9 years and participants generally had moderate-to-severe acne. Across all trials, isotretinoin therapy reduced acne lesion counts by a clinically relevant amount, and always by a greater amount than control, which was either placebo (two studies), oral antibiotics (seven studies) or other control (two studies). Across trials with an overall low risk of bias, two of three demonstrated statistically significant differences between isotretinoin and control. The frequency of adverse events was twice as high with isotretinoin (751 events) than with control (388 events). More than half of all adverse events were dermatological and related to dryness. Adverse events from isotretinoin causing participant withdrawal from trials (12 patients) included Stevens-Johnson syndrome, cheilitis, xerosis, acne flare, photophobia, elevated liver enzymes, decreased appetite, headaches and depressed mood. This review suggests that isotretinoin is effective in reducing acne lesion counts, but adverse events are common. This study was registered with PROSPERO number CRD42015025080.

Abstract
Emergence and potential transfer of antibiotic resistance in skin microorganisms is of current concern in medicine especially in dermatology contexts where long term treatment with antibiotics is common. Remarkably, non-antibiotic therapy in the form of isotretinoin – a non-antimicrobial retinoid is effective at reducing or eradicating the anaerobe Propionibacterium acnes which is causally involved in the complex pathogenesis of Acne vulgaris. This study measured the extent of colonization of P. acnes in patients with primary cystic or severe acne from three defined skin sites in ‘non-lesion’ areas before, during and after treatment with isotretinoin. Patients attending acne clinics were investigated using standardized skin sampling techniques and the recovery of anaerobic P. acnes from 56 patients comprising 24 females and 32 males (mean age 22 years, age range 15–46 years) who were given a standard course of isotretinoin (1 mg/kg/day) are reported. P. acnes cultured from the external cheek surface of patients following treatment showed a significant reduction (1–2 orders of magnitude) compared with their pre-treatment status. Interestingly, other distinct sites (nares and toe web) failed to show this reduction. In addition, high levels of antibiotic-resistant P. acnes were recorded in each patients’ skin microbiota before, during and after treatment. In this study, microbial composition of the skin appears substantially altered by isotretinoin treatment, which clearly has differential antimicrobial effects on each anatomically distinct site. Our study confirmed that orally administered isotretinoin shows good efficacy in the resolution of moderate to severe acne that correlates with reductions in the number of P. acnes on the skin, including resistant isolates potentially acquired from previous treatments with antibiotics. Our study suggests that the role of tetracycline’s and macrolides, which are currently first line treatments in dermatology, might be reserved for severe or life-threatening infections since current antibiotic stewardship guidelines from medical departments no longer prescribe these antibiotics for routine use.

Abstract
The treatment of acne, especially severe acne, remains a challenge to dermatologists. Therapies include retinoids, antibiotics, hormones, lights, lasers, and various combinations of these modalities. Acne is currently considered a chronic rather than an adolescent condition. The appropriate treatment depends on the patient and the severity of disease. The purpose of this study was to review current therapies for acne of all severities and to introduce the 650-μs 1064-nm laser for the treatment of acne.

Abstract
BACKGROUND There is limited evidence on the safety and efficacy of spironolactone in the treatment of women with acne. Thus, for many dermatologists spironolactone remains an alternative rather than a mainstay treatment for female patients with acne. METHODS An electronic medical records search tool was used to select data from a group of women who received spironolactone to treat acne and were evaluated with the comprehensive acne severity scale (CASS) before treatment and at all follow-up visits. Data points were collected for CASS scores at each follow-up visit, concurrent and previous treatments, and side effects. These data points were used to draw conclusions about the safety and efficacy of spironolactone in this patient population. RESULTS There were 110 patients that met all eligibility requirements. Of these, 94 patients saw an improvement in their CASS score and 61 patients completely cleared their score to 0. There were 16 patients who did not improve and six who relapsed after initial improvement. The women saw an average improvement in their acne by 73.1% for the face, 75.9% for the chest, and 77.6% for the back. Fifty-one women experienced side effects, but only six found them bothersome enough to stop taking spironolactone. CONCLUSION A majority of women in this study saw a dramatic improvement in their acne while treated with spironolactone. There were low rates of relapse or discontinuation of the medication. To further promote the use of spironolactone as a first-line systemic treatment for women with acne, there must be more prospective controlled trials.

Abstract
Acne is a very common non-infectious skin condition that is frequently treated in dermatological practices. Because acne is often chronic and may persist for years, safe and effective long-term maintenance therapy is often required. Given the increasing frequency of antibiotic-resistant bacteria and the gravity of the consequences of this trend, it behooves dermatologists to maximize use of non-antimicrobial therapy when treating acne. In this review of the literature we present data regarding the efficacy and appropriate use of non-antimicrobial treatments for acne. A variety of topical and oral treatment options exist that can be used in a step-wise manner according to the patients’ severity and therapeutic response. Non-antimicrobial treatments can be highly efficacious at controlling acne, especially when used as maintenance therapy. While antibiotics have a role in acne treatment, they should not be used as monotherapy, and lengthy courses of antibiotic use are discouraged.

A consensus-based practical and daily guide for the treatment of acne patients. J Eur Acad Dermatol Venereol 2016; 30:1480-90.

Abstract
BACKGROUND Many current guidelines provide detailed evidence-based recommendations for acne treatment. OBJECTIVE To create consensus-based, simple, easy-to-use algorithms for clinical acne treatment in daily office-based practice and to provide checklists to assist in determining why a patient may not have responded to treatment and what action to take. METHODS Existing treatment guidelines and consensus papers were reviewed. The information in them was extracted and simplified according to daily clinical practice needs using a consensus-based approach and based on the authors' clinical expertise. RESULTS As outcomes, separate simple algorithms are presented for the treatment of predominant comedonal, predominant papulopustular and nodular/conglobate acne. Patients with predominant comedonal acne should initially be treated with a topical retinoid, azelaic acid or salicylic acid. Fixed combination topicals are recommended for patients with predominant papulopustular acne with treatment tailored according to the severity of disease. Treatment recommendations for nodular/conglobate acne include oral isotretinoin or fixed combinations plus oral antibiotics in men, and these options may be supplemented with oral anti-androgenic hormonal therapy in women. Further decisions regarding treatment responses should be evaluated 8 weeks after treatment initiation in patients with predominant comedonal or papulopustular acne and 12 weeks after in those with nodular/conglobate acne. Maintenance therapy with a topical retinoid or azelaic acid should be commenced once a patient is clear or almost clear of their acne to prevent the disease from recurring. The principal explanations for lack of treatment response fall into 5 main categories: disease progression, non-drug-related reasons, drug-related reasons, poor adherence, and adverse events. CONCLUSION This practical guide provides dermatologists with treatment algorithms adapted to different clinical features of acne which are simple and easy to use in daily clinical practice. The checklists to establish the causes for a lack of treatment response and subsequent action to take will facilitate successful acne management.

Abstract
Acne is the most common skin disease, affecting up to 95% of adolescents. Severe episodes of acne can cause considerable physical and psychological scarring, and overexpression of transforming growth factor-β can lead to formation of hypertrophic scars and keloids. The severity of acne in adolescence is associated with a positive history of severe acne in first-degree relatives, especially the mother. In most cases acne is a chronic disease, and it is often a component of systemic diseases or syndromes. All forms of severe acne require systemic treatment. The available options include oral antibiotics, hormonal antiandrogens for female patients and oral isotretinoin, as well as other combination treatments. Oral isotretinoin is the only drug available that affects all four pathogenic factors of acne. However, due to possible serious side-effects, a European directive states that oral isotretinoin should be used only as a second-line therapy in cases of severe, nodular and conglobate acne. The pharmaceutical quality of generic isotretinoin products and the obtainability of isotretinoin through e-pharmacies without prescription raise new therapeutic problems. New anti-inflammatory compounds, such as the 5-lipoxygenase inhibitor zileuton, may replace systemic antibiotics in the future, especially under the scope of antibiotic resistance prevention. This review looks into the various options and latest approaches, and factors to consider, when combating severe acne.

Abstract
Background: Oral isotretinoin (ISO) is the standard of care for severe inflammatory acne and a threshold dose of 120-150 mg/kg is widely regarded as increasing remission potential. Objective: Our objective was to evaluate the evidence underlying ISO dosing of 120-150 mg/kg in acne remission. Methods: A systematic literature search was performed using keywords “acne,” “isotretinoin,” “efficacy,” “dosing,” “relapse,” and “remission.” Results: Definitions for acne clearance, relapse/remission, and treatment endpoint vary widely across studies. Only 2 studies explicitly evaluated the cumulative dose of 120-150 mg/kg for induction of acne remission—both low grade. Conclusion: The threshold dose of 120-150 mg/kg for oral ISO is based on past parameters of treatment duration and prior studies used vague or inconsistent definitions of clearance and remission. Optimal cumulative doses of ISO required to induce remission appears to vary with severity.

Abstract
Acne vulgaris is a chronic inflammatory disease of pilosebaceous follicles commonly affecting adolescents and young adults. This disease has a profound psychological impact on affected individuals and treatment has been shown to significantly improve both self-esteem and quality of life. Isotretinoin is an effective medication used primarily in severe cystic acne patients. Over the past 30 years, this medication has revolutionized the treatment of acne. However, despite its popularity there are numerous side effects associated with its use. Most of its side effects are predictable and dose dependent, which has led to the development of variable dose regimens. Unfortunately, rare but significant side effects (e.g., depression, inflammatory bowel disease) do occur and necessitate careful monitoring to improve clinical outcomes and minimize potential adverse events.

Abstract
Background: Despite advances in acne therapy in recent years, treatment failure is common. Isotretinoin is the only drug that affects almost all factors in acne pathogenesis, but side-effects are common at the doses reported in published studies in the literature. The aim of this study was to investigate the efficacy of low daily dose isotretinoin in moderate to severe acne patients. The secondary objective was to measure the rate of relapse 5 years after the completion of therapy. Materials and Methods: In this retrospective, noncomparative study, 146 patients with moderate to severe scare prone acne. Treatment regimen consisted of isotretinoin, fixed 20 mg daily, and duration of treatment-based on the weight of patient, until total cumulative dose of 120 mg/kg of body weight is achieved. No topical or other systemic therapy was allowed during the trial. Liver function tests (serum glutamic-oxalocetic transaminase, serum glutamate pyruvate transaminase, direct and total bilirubin), and lipid profiles (total cholesterol, low-density lipoprotein, high-density lipoprotein, triglyceride) were evaluated for all patients, before the initiation of treatment and again after the 2nd month of treatment. All data analyzed by Microsoft Office Excel 2007; in descriptive statics frequency and SPSS.18 software. Results: At the end of treatment course, (96.4%) demonstrated complete clearing of their acne, defined as no acne or occasional isolated lesions. In 5-year follow-up, relapse accrued in 11 (7.9%) of patients. All adverse effects were mild, and discontinuation of treatment was not necessary. Conclusion: Low dose isotretinoin was found to be a safe and effective choice for patients with moderate to severe scar prone acne vulgaris.

Abstract
Uveitis, recurrent oral and genital ulcerations associated with skin lesions are the major symptoms of a chronic multisystemic inflammatory disorder known as Behçet's disease (BD). High prevalence of this dreaded disease has been observed in the Mediterranean basin, including Algeria and along the Silk Road. Although the etiologic agent of this disease remains uncertain, many hypotheses have been advanced in its pathogenesis. Our team has previously reported high levels of nitric oxide (NO) in sera of BD patients, suggesting its deleterious effect during chronic inflammation. In our current study, the aim is to investigate the ex vivo immunomodulatory effect of all-trans-retinoic acid (ATRA) on NO pathway in Algerian BD patients. First, peripheral blood mononuclear cells isolated from active and inactive BD patients and healthy controls were cultured with different concentrations of ATRA. NO production was estimated with the Griess method. To elucidate the underlying mechanisms of ATRA effect on NO production, we analyze inducible nitric oxide synthase expression and nuclear factor-κB (NF-κB) activity by immunofluorescence test. Our results revealed a higher production of NO in active BD compared with the inactive stage and healthy controls. We observed that ATRA inhibits NO production in BD both in active and inactive stages and inhibits NF-κB translocation. In conclusion, we report a relationship between NO production and the disease activity. ATRA down-regulates NO production in BD patients. This immunomodulatory effect seems to be mediated through NF-κB pathway. All these findings suggest that ATRA could be considered as a promising therapy for BD.

Abstract
BACKGROUND Crowdsourcing is a novel process of data collection that can provide insight into the effectiveness of acne treatments in real-world settings. Little is known regarding the feasibility of crowdsourcing as a means of collecting dermatology research data, the quality of collected data, and how the data compare to the published literature. OBJECTIVE The objective of this analysis is to compare acne data collected from a medical crowdsourcing site with high-quality controlled studies from peer-reviewed medical literature. METHODS Crowdsourced data was collected from 662 online acne patients. Online patients reported data in a Likert-type format to characterize their symptom severity (740 total responses) and their treatment outcomes (958 total responses). The crowdsourced data were compared with meta-analyses and reviews on acne treatment from August 20, 2010 to August 20, 2011. RESULTS We compared topical, oral systemic, alternative, phototherapy, and physical acne treatments of crowdsourced data to published literature. We focused on topical tretinoin due to the large number of online patient responses. While approximately 80% of tretinoin users observed clinical improvement after a 12-week treatment period in clinical trials, 46% of online users reported improvement in an unspecified time period. For most topical treatments, medication with high efficacy in clinical trials did not produce high effectiveness ratings based on the crowdsourced online data. CONCLUSION While limitations exist with the current methods of crowdsourced data collection, with standardization of data collection and use of validated instruments, crowdsourcing will provide an important and valuable platform for collecting high-volume patient data in real-world settings.

Abstract
Lupus nephritis is a major cause of morbidity and mortality among patients with systemic lupus erythematosus (SLE). In these patients, treatment with immunosuppressive agents can significantly improve the outcome of lupus nephritis. However, these agents have severe adverse reactions and some patients are refractory to those therapies. Retinoids, a group of natural and synthetic derivatives of vitamin A, play important regulatory roles of cellular proliferation, differentiation and apoptosis. They have been used for the treatment of acute promyelocytic leukemia and inflammatory disorders such as psoriasis and acne. It has also been shown that retinoids have therapeutic effects in various animal models of kidney disease, including lupus nephritis. Based on these findings, retinoids are a promising agent for the treatment of lupus nephritis. We studied the clinical effects of retinoid therapy in patients with lupus nephritis. In open clinical trial, 7 patients with active lupus nephritis that was refractory to steroid therapy were studied. In all these patients, retinoid was added to the immunosuppressive therapy and its therapeutic effects were evaluated. As a result, 4 out of 7 patients showed improvement of the clinical symptoms and laboratory findings, including urinary protein and anti-dsDNA antibody levels. No important adverse effects of ATRA therapy were observed in all patients. Thus, retinoids might be indicated in cases of lupus nephritis that are refractory to conventional immunosuppressive therapy.

Abstract
CLINICAL QUESTION What are the most effective treatment(s) for mild, moderate, severe, and hormonally driven acne? RESULTS Mild acne responds favorably to topical treatments such as benzoyl peroxide, salicylic acid, and a low-dose retinoid. Moderate acne responds well to combination therapy comprising-topical benzoyl peroxide, antibiotics, and/or retinoids, as well as oral antibiotics in refractory cases and oral contraceptive pills for female acne patients. Severe nodulocystic acne vulgaris responds best to oral isotretinoin therapy. In female patients with moderate to severe acne, facial hair, loss of scalp hair and irregular periods, polycystic ovarian syndrome should be considered and appropriate treatment with hormonal modulation given. Adjunctive procedures can also be considered for all acne patients. IMPLEMENTATION PITFALLS TO AVOID WHEN TREATING ACNE: treatment of acne in women of child-bearing age; familiarization of all acne treatments in order to individualize management for patients; indications for specialist referral.

Abstract
BACKGROUND Retinoic acids, a group of natural and synthetic vitamin A derivatives, have potent anti-proliferative, anti-inflammatory and anti-fibrotic properties. We investigated the therapeutic effect of all-trans-retinoic acid (ATRA) on unilateral ureteral obstruction (UUO) model mice. METHODS First, to evaluate the prophylactic effect, we administered 0.5 mg of ATRA for 3 days before UUO (UUO ATRA). Then, to evaluate the therapeutic effects, we administered 0.5 mg of ATRA 3 days after UUO (Day 3 ATRA). We compared the histological changes and immunostaining of macrophages, α-smooth muscle actin (α-SMA) and collagen I, and mRNA expression of monocyte chemotactic protein-1 (MCP-1), transforming growth factor (TGF)-β(1) and TGF-β R-II by RT-PCR 7 days after UUO. RESULTS In the UUO ATRA and Day 3 ATRA groups, we observed a significant improvement in histological and immunological findings, including macrophage infiltration and improved expression of MCP-1, TGF-β(1), α-SMA and collagen I compared with the UUO Day 7 group. CONCLUSION ATRA treatment is not only an effective prophylactic strategy, but also a therapeutic strategy for the treatment of progressive renal fibrosis in diseased kidneys.

Abstract
OBJECTIVES Case reports have described a possible association between isotretinoin and inflammatory bowel disease (IBD). We critically appraised the literature on this association to assess whether it supports a causal relationship. METHODS We systematically searched for case reports, case series, and clinical trials assessing this association. We then applied the Hill criteria to evaluate causality. RESULTS Twelve case reports and one case series reported an association between isotretinoin use and subsequent development of IBD. Cases occurred in seven countries over a 23-year period and differed with respect to reported isotretinoin dose, duration of treatment before development of disease, whether disease developed on or off medication, and clinical presentation of disease. No prospective or retrospective studies have examined the relationship between isotretinoin and IBD. An estimated 59 coincident cases of IBD would be expected in isotretinoin users each year, assuming no increased risk. Alternative explanations may account for the sequence of events seen in case reports. Strength, specificity, and consistency of the association are lacking. CONCLUSIONS Current evidence is insufficient to confirm or refute a causal association between isotretinoin and IBD. Additional prospective or well-designed retrospective (e.g., case-control) pharmacoepidemiological studies are needed to definitively establish causality.

Abstract
Lupus nephritis is a major manifestation of systemic lupus erythematosus. Treatment with such immunosuppressive agents as corticosteroids or cyclophosphamide can decrease the progression of lupus nephritis; however, these agents have potentially severe adverse reactions. Therefore, the development of new drugs with fewer side effects is needed. Here, we report 2 patients with lupus that were treated successfully with retinoids. Initially, both patients were treated with 60 mg/d of prednisolone. However, nephrotic syndrome was not improved. Subsequently, treatment with 10 mg/d of all-trans-retinoic acid was started orally and elicited a good response, showing a decrease in proteinuria. Although additional controlled clinical studies are needed to confirm these findings, we suggest that therapy using retinoids may represent a novel approach to the treatment of patients with lupus nephritis.

Abstract
BACKGROUND Isotretinoin is the only drug that affects almost all factors in acne pathogenesis. Recently, its use for the treatment of chronic mild or moderate acne unresponsive to long-term antibiotic therapy, and with a tendency to cause scarring and leading to negative psychological effects, has became popular. The aim of the study was to investigate the effectiveness of intermittent isotretinoin treatment in mild or moderate acne. METHODS Sixty patients with mild or moderate acne localized to the face were enrolled in the study. The treatment regimen consisted of isotretinoin, 0.5-0.75 mg/kg per day, applied for 1 week every 4 weeks for a total period of 6 months, according to the degree of acne and number of inflammatory lesions. RESULTS Forty-one (68.3%) of the 60 patients completed the 6-month therapy. At the end of the treatment complete improvement was observed in 34 patients (82.9%) out of 41. All adverse effects were mild and discontinuation of the treatment was not necessary. CONCLUSION Intermittent isotretinoin treatment was found to be a safe and effective choice for patients with mild or moderate acne.

Abstract
BACKGROUND Retinoids and active vitamin D(3) analogues regulate the proliferation and differentiation of keratinocytes and are effective in the treatment of psoriasis. Retinoids are known to be effective against acne vulgaris through comedolysis. However, the comedolytic effect of active vitamin D(3) analogues has not been reported. OBJECTIVES To investigate whether maxacalcitol, one of the active vitamin D(3) analogues, has a comedolytic effect by using spontaneously comedogenic rhino mice. METHODS Rhino mice were treated topically with tretinoin and maxacalcitol once daily for 2 and 4 weeks, respectively. The dermal side of the epidermal sheet was observed to determine the size of the utricle. Haematoxylin and eosin-stained vertical sections were used to measure utricle diameter and density and to evaluate histological changes. RESULTS Maxacalcitol (25 microg g(-1)) and tretinoin (0.1%) significantly decreased the size and the diameter of the utricle after 1 week of treatment. However, maxacalcitol did not affect the density while tretinoin did have an effect. Histopathologically, maxacalcitol and tretinoin markedly induced epidermal hyperplasia accompanied by a minor accumulation of inflammatory cells in the dermis, with and without hypercornification, respectively. CONCLUSIONS These results indicate that maxacalcitol has a prominent effect on comedolysis and that its mechanism of action may be different from that of retinoids.

Abstract
Acne is one of the most prevalent skin conditions affecting teenagers. It is a disease of the pilosebaceous unit. Blockage of sebaceous glands and colonisation with Proionobacterium acnes leads to acne. Grading the severity of acne helps to determine the appropriate treatment. Treatment of acne should be started as early as possible to minimise the risk of scarring and adverse psychological effects. It should be tailored to the individual patient, the type of acne, its severity, the patient's ability to use the treatment, and the psychological state. Topical agents are the mainstay for treatment of mild acne. Moderate acne is treated with oral antibiotics. Resistance to antibiotics may be reduced by subsequent use of non-antibiotic topical medications. Severe acne is treated with isotretinoin, and this can lead to permanent remission. With better education and care given by medical profession, acne treatment could be significantly improved.

Abstract
OBJECTIVE To determine whether all-trans-retinoic acid (ATRA) improves the destruction of joints and the effect of cytokines on DBA/1J mice with collagen-induced arthritis (CIA). METHODS Starting from the time of type II collagen injection, DBA/1J mice were injected intraperitoneally with PBS or 0.5 mg of ATRA 3 times per week for 35 days. The effects of treatment were monitored by determining arthritis and histological scores and measuring cellular proliferation, production of cytokines (IL-2, IL-10, IL-12, IL-6, IFN-gamma, and TNF-alpha) and IgG, and the expression of mRNAs for inducible nitric oxide synthase (iNOS), monocyte chemoattractant protein-1 (MCP-1), and CXCR3. RESULTS The arthritis score and incidence of arthritis were lower in the mice treated with ATRA than in those treated with PBS. Histopathologic evidence of joint damage was 34% lower, and the infiltrations of macrophages were reduced in the mice treated with ATRA compared with those treated with PBS. Type II collagen- and ConA-stimulated proliferation of spleen cells, the production of cytokines (IL-6, IL-12, and TNF-alpha), the serum levels of total IgG and IgG1 anti-collagen antibodies, and the expression of mRNAs for MCP-1 were significantly reduced in the mice treated with ATRA than in those treated with PBS. CONCLUSION ATRA improved the clinical course and reduced the production of inflammatory cytokines, immunoglobulin, and chemokines in murine CIA. These data suggest that ATRA might be also effective for the treatment of inflammatory arthritis like human rheumatoid arthritis.

Abstract
Isotretinoin treatment alters the plasma lipid levels but the mechanisms and the effects on the metabolism of triglyceride-rich lipoproteins such as chylomicrons and very-low-density lipoproteins remain unclear. We investigated the effect of isotretinoin on the plasma kinetics of emulsion models of triglyceride-rich lipoproteins and the lipid profile. Ten patients with acne were treated with 0.8 mg/kg of isotretinoin over 4 weeks for comparison with non-treated acne patients. In both groups the plasma kinetic study of a triglyceride-rich emulsion double-labeled with 14C-cholesterol oleate and 3H-triolein was performed after intravenous injection of the emulsion and radioactive counting in plasma samples collected over 60 min. Patients using isotretinoin showed decreased removal from the plasma of the 3H-triglyceride (median 0.019 min-1 TG) compared with controls (median 0.044 min-1, P=0.007), and the removal of the emulsion 14C-cholesterol oleate also tended to be decreased (treatment: 0.011 min-1; controls: 0.024 min-1, P=0.06). The values of total and LDL cholesterol and triglycerides were increased post-treatment (P<0.03). In conclusion, while increasing the fasting plasma concentration of VLDL and LDL, which are traditional risk factors for atherosclerosis, isotretinoin treatment also slows down the metabolism of triglyceride-rich lipoproteins such as chylomicrons, as tested by the emulsion model, an effect that is also increasingly recognized as atherogenic.

Abstract
Corticosteroids are highly effective anti-inflammatory or immunosuppressive drugs used commonly to treat human systemic lupus erythematosus (SLE). All-trans-retinoic acid (ATRA), which belongs to a class of retinoids that exert immunomodulatory and anti-inflammatory functions, can also suppress the development of lupus nephritis in an animal model. However, both agents can inflict serious adverse effects. Here, we have asked whether ATRA can serve as a steroid-sparing drug in the treatment of lupus nephritis. To examine the efficacy of combining predonisolone (PSL) with ATRA, we treated intraperitoneally New Zealand black/white F1 (NZB/W F1) mice with PSL, ATRA or both agents. Survival rate and proteinuria were determined once a month. Cytokine and anti-DNA antibody production were determined by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). Renal histopathology was observed by haematoxylin and periodic acid Schiff (PAS), immunoperoxidase and immunohistochemical assay. Survival rate and proteinuria were improved in all experimental groups, and were much improved in the mice receiving the combination of ATRA and PSL (P <0.05). A single administration of ATRA reduced the Th1 [interleukin (IL)-2, interferon (IFN)-gamma and IL-12], and a Th2 (IL-4) cytokine level, as effectively as administration of PSL. ATRA also suppressed the expression of inducible nitric oxide synthetase (iNOS) and monocyte chemoattractant protein-1 (MCP-1) in the kidney. The combination of PSL and ATRA significantly reduced IgG2 (especially IgG2b)-specific anti-DNA antibody levels in comparison with administration of either agent alone. These data suggest that ATRA might have the potential to act as a new therapeutic and steroid-sparing drug against lupus nephritis.
