Glucocorticoids in the treatment of rheumatic diseases: an update on the mechanisms of action

Lupus nephritis: management challenges during pregnancy

Lupus nephritis (LN), a severe complication of systemic lupus erythematosus (SLE), leads to significant kidney inflammation and damage and drastically increases mortality risk. Predominantly impacting women in their reproductive years, LN poses specific risks during pregnancy, including pre-eclampsia, growth restrictions, stillbirth, and preterm delivery, exacerbated by lupus activity, specific antibodies, and pre-existing conditions like hypertension. Effective management of LN during pregnancy is crucial and involves carefully balancing disease control with the safety of the fetus. This includes pre-conception counseling and a multidisciplinary approach among specialists to navigate the complexities LN patients face during pregnancy, such as distinguishing LN flare-ups from pregnancy-induced conditions. This review focuses on exploring the complex dynamics between pregnancy and LN, emphasizing the management difficulties and the heightened risks pregnant women with LN encounter.

Unintended Consequences: Risk of Opportunistic Infections Associated With Long-term Glucocorticoid Therapies in Adults

Glucocorticoids are widespread anti-inflammatory medications used in medical practice. The immunosuppressive effects of systemic glucocorticoids and increased susceptibility to infections are widely appreciated. However, the dose-dependent model frequently used may not accurately predict the risk of infection in all patients treated with long-term glucocorticoids. In this review, we examine the risks of opportunistic infections (OIs) in patients requiring glucocorticoid therapy by evaluating the influence of the glucocorticoid dose, duration, and potency, combined with biological and host clinical factors and concomitant immunosuppressive therapy. We propose strategies to prevent OIs, which involve screening, antimicrobial prophylaxis, and immunizations. While this review focuses on patients with autoimmune, inflammatory, or neoplastic diseases, the potential risks and preventative strategies are likely applicable to other populations. Clinicians should actively assess the benefit-harm ratios of systemic glucocorticoids and implement preventive efforts to decrease their associated infections complications.

Balancing risks and benefits in the use of hydroxychloroquine and glucocorticoids in systemic lupus erythematosus

INTRODUCTION

Hydroxychloroquine (HCQ) and glucocorticoids (GCs) constitute the oldest and more used drugs in the treatment of systemic lupus erythematosus (SLE). Despite this long experience, both are still subject to a number of uncertainties, mainly regarding the dose.

AREAS COVERED

We review the main mechanisms of action, the clinical and toxic effects of HCQ and GCs and analyze the recommendations for the use of both in guidelines published since 2018. We offer a set of recommendations based on the pharmacology, mechanisms of action and clinical evidence.

EXPERT OPINION

HCQ is the backbone therapy for SLE, and a judicious use must be accomplished, using doses that allow a good control of lupus without compromising the safety of treatments very much prolonged over the time. Stable doses of 200 mg/day seem to accomplish both conditions. GCs should be used more judiciously, with methyl-prednisolone pulses as the main therapy for inducing rapid remission and doses ≤5-2.5 mg/day be never exceeded in long-term maintenance treatments.

Is it safe to withdraw low-dose glucocorticoids in SLE patients in remission?

Glucocorticoids (GCs) remain a cornerstone of the treatment of Systemic Lupus Erythematosus (SLE). Numerous studies have emphasized the risk of damage accrual in SLE patient treated with GC, but currently, it is not possible to dissociate favorable and undesirable effects of GCs because their underlying mechanisms are entangled at the molecular level. Here, we review whether available data suggest that it is possible, feasible and desirable to taper and discontinue GC treatment in SLE. The main potential concern with GC withdrawal is the risk of SLE flare, which is strongly associated with increased organ damage, mortality, healthcare costs, decreased quality of life and work productivity. While most studies have assumed the cut off point for low doses (e.g. 7.5/mg/d) as the limit for safety, it is still controversial whether lower doses may influence damage accrual long-term. Also, a recent randomized trial has shown that a daily dose of 5 mg of prednisone in SLE patients in short-term remission can prevent up to 50-75% of flares, with an acceptable safety profile. However, this treatment is not mandatory for all patients. Yet, several observational studies highlight that discontinuation of GC is associated with lower damage accrual. Currently, we do not have a reliable method to identify patients who may require long-term low-dose GC. Therefore, further research is needed to identify a subgroup at high risk of relapse who would benefit from continuing prednisone. In the meantime, when considering the discontinuation of very low-dose prednisone, the decision must be individualized, as HCQ and conventional immunosuppressive agents are not without risk of side effects.

Systemic lupus erythematosus and glucocorticoids: A never-ending story?

Glucocorticoids (GCs) continue to be essential agents for the management of systemic lupus erythematosus, since there are no other drugs able to active remission of active disease so rapidly. However, their potential for causing irreversible damage greatly limit their use. Fortunately, some strategies may help take advantage of their huge anti-inflammatory power while limiting GC-induced side effects. This article reviews the pharmacological basis of GC action and their translation into the clinical ground. We also offer the practical approach for the use of GC in induction and maintenance therapy as well as the strategies for GC withdrawal of the respective practice of the authors. The three main basic principles are a) using methyl-prednisolone pulses to induce remission not only in severe disease; b) limiting initial doses of prednisone to ≤30 mg/d, with rapid tapering to ≤5 mg/d, which should be the dose for maintenance therapy; and c) individualizing the decision and the strategy to withdraw GCs. Long-term therapy with HCQ and the early introduction of immunosuppressive treatment would help achieve these objectives.

Changes in Arterial Stiffness Monitored Using the Cardio-Ankle Vascular Index in Patients with Rheumatic Disease Receiving Initial Glucocorticoid Therapy: A Clinical Pilot Study

Systemic inflammatory rheumatic diseases predispose to premature birth, accelerated atherosclerosis, and increased cardiovascular disease (CVD). While glucocorticoids (GCs) are used in various rheumatic diseases, and the associations between GC excess and increased prevalence of CVD complications are well established, the mechanisms underlying GCs' role in atheroma development are unclear. We conducted an observational study to address GC therapy's effect on arterial stiffness using the cardio-ankle vascular index (CAVI) in patients with rheumatic diseases. Twenty-eight patients with rheumatic disease received initial GC therapy with prednisolone at doses ranging from 20 to 60 mg/d. CAVI was examined at baseline and 3 and 6 months after GC therapy. Changes in CAVI and inflammatory parameters were evaluated. GC therapy increased the mean CAVI after 3 months but decreased it to pretreatment levels after 6 months. The mean CAVI substantially decreased with GC treatment in patients <65 years but increased in patients ≥65 years. Alterations in CAVI during the 6-month GC treatment negatively correlated with the lymphocyte-to-monocyte ratio (LMR) at baseline. Conversely, no correlation was observed between alterations in CAVI values and conventional inflammatory markers (C-reactive protein and erythrocyte sedimentation rate). Multivariate analysis of factors related to changes in CAVI highlighted young age, high prednisolone dosage, and LMR at baseline. GC temporarily exacerbates but eventually improves arterial stiffness in rheumatic diseases. Particularly in young patients, GC may improve arterial stiffness by reducing inflammation. Therefore, the LMR before GC therapy in rheumatic diseases may be a potential predictor of arterial stiffness.

Advancement in nanotechnology for treatment of rheumatoid arthritis: scope and potential applications

Rheumatoid arthritis is a hyperactive immune disorder that results in severe inflammation in synovial joints, cartilage, and bone deterioration, resulting in immobilization of joints. Traditional approaches for the treatment of rheumatoid arthritis are associated with some limiting factors such as suboptimal patient compliance, inability to control the progression of disorder, and safety concerns. Therefore, innovative drug delivery carriers for efficient therapeutic delivery at inflamed synovial sites with better safety assessment are urgently needed to address these issues. From this perspective, nanotechnology is an outstanding alternative to traditional drug delivery approaches, and it has shown great promise in developing novel carriers to treat rheumatoid arthritis. Considering the current research and future application of nanocarriers, it is believed that nanocarriers can be a crucial element in rheumatoid arthritis treatment. This paper covers all currently available pathophysiological aspects of rheumatoid arthritis and treatment options. Future research for the reduction of synovial inflammation should focus on developing multifunction nanoparticles capable of delivering therapeutic agents with improved safety, efficacy, and cost-effectiveness to be commercialized.

Comparative analysis between the safety and efficacy of oral corticosteroids versus corticosteroids pulse therapies in IgA nephropathy

OBJECTIVE

This study retrospectively compared the safety and efficacy of oral corticosteroid therapy (OCT) and corticosteroid pulse therapy (CPT) in the treatment of IgA nephropathy.

METHODS

One ninety-two patients were diagnosed with IgA nephropathy and had an estimated glomerular filtration rate > 15mL/min/1.73m2 and 24-h urine protein level of 0.75-3.5g. Patients were divided into CPT and OCT groups according to the treatment protocol. The differences in the efficacy and safety between the two groups were assessed by logistic regression analysis and propensity score matching.

RESULTS

Significant differences at baseline, including 24-h urine protein level and eGFR, were observed between the two groups. Logistic regression analysis indicated that the remission rate increased significantly, while the incidences of total adverse events and infections decreased in CPT group compared with the OCT group after adjusting the potential confounding factors. Forty-seven pairs of subjects are matched by using propensity score matching with similar baseline data. The results indicate that the total remission rate and complete remission rate were significantly higher, while the incidences of total adverse events were lower (p = 0.008) in the CPT group than in the OCT group. The subgroup analysis showed that CPT group was more likely to achieve remission in patients with initial 24-h urine protein levels falling into the range of 2-3.5 g and Oxford Classification of S1 or C1/2 (p < 0.05).

CONCLUSION

Among patients with IgA nephropathy and 24-h urine protein levels of 0.75-3.5g, CPT may be more effective than OCT in reducing urinary protein levels and improving renal function with a lower incidence of adverse events.

Transgenic disruption of endogenous glucocorticoid signaling in osteoblasts does not alter long-term K/BxN serum transfer-induced arthritis

BACKGROUND

Disruption of glucocorticoid (GC) signaling in osteoblasts results in a marked attenuation of acute antibody-induced arthritis. The role of endogenous GCs in chronic inflammatory arthritis is however not fully understood. Here, we investigated the impact of endogenous GC signaling in osteoblasts on inflammation and bone integrity under chronic inflammatory arthritis by inactivating osteoblastic GC signaling in a long-term K/BxN serum transfer-induced induced arthritis (STIA) model.

METHODS

Intracellular GC signaling in osteoblasts was disrupted by transgenic (tg) overexpression of 11beta-hydroxysteroid dehydrogenase type 2 (11ß-HSD2). Inflammatory arthritis was induced in 5-week-old male tg mice and their wild type (WT) littermates by intraperitoneal (i.p.) injection of K/BxN serum while controls (CTRLs) received phosphate-buffered saline (PBS). In a first cohort, K/BxN STIA was allowed to abate until  the endpoint of 42 days (STIA). To mimic rheumatic flares, a second cohort was additionally injected on days 14 and 28 with K/BxN serum (STIA boost). Arthritis severity was assessed daily by clinical scoring and ankle size measurements. Ankle joints were assessed histopathologically. Systemic effects of inflammation on long bone metabolism were analyzed in proximal tibiae by micro-computed tomography (μCT) and histomorphometry.

RESULTS

Acute arthritis developed in both tg and WT mice (STIA and STIA boost) and peaked around day 8. While WT STIA and tg STIA mice showed a steady decline of inflammation until day 42, WT STIA boost and tg STIA boost mice exhibited an arthritic phenotype over a period of 42 days. Clinical arthritis severity did not differ significantly between WT and tg mice, neither in the STIA nor in the STIA boost cohorts. Correspondingly, histological indices of inflammation, cartilage damage, and bone erosion showed no significant difference between WT and tg mice on day 42. Histomorphometry revealed an increased bone turnover in tg CTRL and tg STIA boost compared to WT CTRL and WT STIA boost animals, respectively.

CONCLUSIONS

In contrast to the previously reported modulating effects of endogenous GC signaling in osteoblasts during acute K/BxN STIA, this effect seems to perish during the chronic inflammatory and resolution phase. These findings indicate that endogenous GC signaling in osteoblasts may mainly be relevant during acute and subacute inflammatory processes.

Glucocorticoid Treatment in Acute Respiratory Distress Syndrome: An Overview on Mechanistic Insights and Clinical Benefit

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS), triggered by various pathogenic factors inside and outside the lungs, leads to diffuse lung injury and can result in respiratory failure and death, which are typical clinical critical emergencies. Severe acute pancreatitis (SAP), which has a poor clinical prognosis, is one of the most common diseases that induces ARDS. When SAP causes the body to produce a storm of inflammatory factors and even causes sepsis, clinicians will face a two-way choice between anti-inflammatory and anti-infection objectives while considering the damaged intestinal barrier and respiratory failure, which undoubtedly increases the difficulty of the diagnosis and treatment of SAP-ALI/ARDS. For a long time, many studies have been devoted to applying glucocorticoids (GCs) to control the inflammatory response and prevent and treat sepsis and ALI/ARDS. However, the specific mechanism is not precise, the clinical efficacy is uneven, and the corresponding side effects are endless. This review discusses the mechanism of action, current clinical application status, effectiveness assessment, and side effects of GCs in the treatment of ALI/ARDS (especially the subtype caused by SAP).

Pharmacological approaches to pulmonary fibrosis following COVID-19

Background: In the past few years, COVID-19 became the leading cause of morbidity and mortality worldwide. Although the World Health Organization has declared an end to COVID-19 as a public health emergency, it can be expected, that the emerging new cases at the top of previous ones will result in an increasing number of patients with post-COVID-19 sequelae. Despite the fact that the majority of patients recover, severe acute lung tissue injury can in susceptible individuals progress to interstitial pulmonary involvement. Our goal is to provide an overview of various aspects associated with the Post-COVID-19 pulmonary fibrosis with a focus on its potential pharmacological treatment options. Areas covered: We discuss epidemiology, underlying pathobiological mechanisms, and possible risk and predictive factors that were found to be associated with the development of fibrotic lung tissue remodelling. Several pharmacotherapeutic approaches are currently being applied and include anti-fibrotic drugs, prolonged use or pulses of systemic corticosteroids and non-steroidal anti-inflammatory and immunosuppressive drugs. In addition, several repurposed or novel compounds are being investigated. Fortunately, clinical trials focused on pharmacological treatment regimens for post-COVID-19 pulmonary fibrosis have been either designed, completed or are already in progress. However, the results are contrasting so far. High quality randomised clinical trials are urgently needed with respect to the heterogeneity of disease behaviour, patient characteristics and treatable traits. Conclusion: The Post-COVID-19 pulmonary fibrosis contributes to the burden of chronic respiratory consequences among survivors. Currently available pharmacotherapeutic approaches mostly comprise repurposed drugs with a proven efficacy and safety profile, namely, corticosteroids, immunosuppressants and antifibrotics. The role of nintedanib and pirfenidone is promising in this area. However, we still need to verify conditions under which the potential to prevent, slow or stop progression of lung damage will be fulfilled.

Intravenous cyclophosphamide improves functional outcomes in interstitial lung disease related to idiopathic inflammatory myopathies

OBJECTIVE

To compare the efficacy, toxicity and glucocorticoid (GC)-sparing effects of intravenous cyclophosphamide (iv CYC) with other immunosuppressive regimes as the induction treatment for Idiopathic Inflammatory Myopathy-Related Interstitial Lung Disease (IIM-ILD).

METHODS

Observational comparative study of patients with IIM-ILD from the EPIMAR and Cruces cohorts. The main efficacy outcome was a 6 to 12-month improvement >10% in the forced vital capacity (FVC) from baseline.

RESULTS

Overall, 47 patients were included: 22 (47%) in the CYC group and 25 (53%) in the non-CYC group (32% azathioprine, 28% GC alone, 20% mycophenolate, 16% calcineurin-inhibitors and methotrexate and 4% rituximab). 81% patients were female with a mean age of 50.4 years. FVC improvement was achieved by 64% patients in the CYC group vs. 32% in the non-CYC group (p = 0.03). In the logistic regression model, CYC was identified as the only independent predictor of FVC improvement (OR=3.97, 95% CI 1.07-14.75). Patients in the CYC group received more methyl-prednisolone pulses (MP) (59% vs. 28% in the non-CYC group, p = 0.03), less initial GCs doses >30 mg/d (19% vs. 77%, p = 0.001) and lower 6-month average doses of prednisone (11 mg/d vs. 31.1 mg/d, p = 0.001).

CONCLUSION

iv CYC showed better functional outcomes than other immunosuppressants in IIM-ILD. The additional use of MP is likely to potentiate the effects of CYC and allows lowering prednisone doses. Therefore, CYC in combination with MP could be considered as the first line induction therapy in IIM-ILD, without limiting its use to rapidly progressive, life-threatening or refractory disease.

Comparison of mechanisms of angiostasis caused by the anti-inflammatory steroid 5α-tetrahydrocorticosterone versus conventional glucocorticoids

5α-Tetrahydrocorticosterone (5αTHB) is an effective topical anti-inflammatory agent in mouse, with less propensity to cause skin thinning and impede new blood vessel growth compared with corticosterone. Its anti-inflammatory effects were not prevented by RU38486, a glucocorticoid receptor antagonist, suggesting alternative mechanisms. The hypothesis that 5αTHB directly inhibits angiogenesis to a lesser extent than hydrocortisone was tested, focussing on glucocorticoid receptor mediated actions. New vessel growth from aortae from C57BL/6 male mice was monitored in culture, in the presence of 5αTHB, hydrocortisone (mixed glucocorticoid/mineralocorticoid receptor agonist) or the selective glucocorticoid receptor agonist dexamethasone. Transcript profiles were studied, as was the role of the glucocorticoid receptor, using the antagonist, RU38486. Ex vivo, 5αTHB suppressed vessel growth from aortic rings, but was less potent than hydrocortisone (EC50 2512 nM 5αTHB, versus 762 nM hydrocortisone). In contrast to conventional glucocorticoids, 5αTHB did not alter expression of genes related to extracellular matrix integrity or inflammatory signalling, but caused a small increase in Per1 transcript, and decreased transcript abundance of Pecam1 gene. RU38486 did not antagonise the residual effects of 5αTHB to suppress vessel growth or regulate gene expression, but modified effects of dexamethasone. 5αTHB did not alter expression of glucocorticoid-regulated genes Fkbp51 and Hsd11b1, unlike hydrocortisone and dexamethasone. In conclusion, compared with hydrocortisone, 5αTHB exhibits limited suppression of angiogenesis, at least directly in blood vessels and probably independent of the glucocorticoid receptor. Discriminating the mechanisms employed by 5αTHB may provide the basis for the development of novel safer anti-inflammatory drugs for topical use.

Anti-rheumatoid drugs advancements: New insights into the molecular treatment of rheumatoid arthritis

Rheumatoid arthritis (RA) is one of more than 100 types of arthritis. This chronic autoimmune disorder affects the lining of synovial joints in about 0.5% of people and may induce severe joints deformity and disability. RA impacts health life of people from all sexes and ages with more prevalence in elderly and women people. Significant improvement has been noted in the last two decades revealing the mechanisms of the development of RA, the improvement of the early diagnosis and the development of new treatment options. Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and disease-modifying antirheumatic drugs (DMARDs) remain the most known treatments used against RA. However, not all patients respond well to these drugs and therefore, new solutions are of immense need to improve the disease outcomes. In the present review, we discuss and highlight the recent findings concerning the different classes of RA therapies including the conventional and modern drug therapies, as well as the recent emerging options including the phyto-cannabinoid and cell- and RNA-based therapies. A better understanding of their mechanisms and pathways might help find a specific target against inflammation, cartilage damage, and reduce side effects in arthritis.

Intravenous methylprednisolone pulses in hospitalised patients with severe COVID-19 pneumonia, A double-blind, randomised, placebo-controlled trial

Rationale

Pulse glucocorticoid therapy is used in hyperinflammation related to coronavirus disease 2019 (COVID-19). We evaluated the efficacy and safety of pulse intravenous methylprednisolone in addition to standard treatment in COVID-19 pneumonia.

Methods

In this multicentre, randomised, double-blind, placebo-controlled trial, 304 hospitalised patients with COVID-19 pneumonia were randomised to receive 1 g of methylprednisolone intravenously for three consecutive days or placebo in addition to standard dexamethasone. The primary outcome was the duration of patient hospitalisation, calculated as the time interval between randomisation and hospital discharge without the need for supplementary oxygen. The key secondary outcomes were survival free from invasive ventilation with orotracheal intubation and overall survival.

Results

Overall, 112 (75.4%) out of 151 patients in the pulse methylprednisolone arm and 111 (75.2%) of 150 in the placebo arm were discharged from hospital without oxygen within 30 days from randomisation. Median time to discharge was similar in both groups (15 days, 95% CI 13.0–17.0 days and 16 days, 95% CI 13.8–18.2 days, respectively; hazard ratio (HR) 0.92, 95% CI 0.71–1.20; p=0.528). No significant differences between pulse methylprednisolone and placebo arms were observed in terms of admission to intensive care unit with orotracheal intubation or death (20.0% versus 16.1%; HR 1.26, 95% CI 0.74–2.16; p=0.176) or overall mortality (10.0% versus 12.2%; HR 0.83, 95% CI 0.42–1.64; p=0.584). Serious adverse events occurred with similar frequency in the two groups.

Conclusions

Methylprenisolone pulse therapy added to dexamethasone was not of benefit in patients with COVID-19 pneumonia.

The quick and strong anti-inflammatory effect of pulse glucocorticoid therapy seems to be of no benefit in COVID-19 pneumoniahttps://bit.ly/3IkUmSn

Controversies in Systemic Lupus Erythematosus: Are We Treating Our Patients Adequately?

ABSTRACT

Systemic lupus erythematosus (SLE) is characterized by great clinical heterogeneity. The objectives of its management are to make a timely diagnosis and to initiate treatment as promptly as possible so organ damage can be avoided while at the same time exposure to potentially toxic drugs is minimized so that its overall course and outcome improve. In reviewing the current literature, it became quite clear that there are specific topics in which controversies do exist. These include how to treat patients with incomplete lupus erythematosus, the real possibility of abandoning altogether the use of oral glucocorticoids, and the pros and cons of the use of cyclophosphamide and mycophenolate mofetil for the induction treatment of lupus nephritis. Herein we discuss different points of view regarding these still unresolved issues; these comments represent a debate that took place during the PANLAR Virtual Congress (Pan American League of Associations for Rheumatology) and that was organized by the PANLAR Lupus study group, GLADEL (Grupo Latino Americano De Estudio del Lupus) on September 19, 2020.

Use of glucocorticoids megadoses in SARS-CoV-2 infection in a spanish registry: SEMI-COVID-19

OBJECTIVE

To describe the impact of different doses of corticosteroids on the evolution of patients with COVID-19 pneumonia, based on the potential benefit of the non-genomic mechanism of these drugs at higher doses.

METHODS

Observational study using data collected from the SEMI-COVID-19 Registry. We evaluated the epidemiological, radiological and analytical scenario between patients treated with megadoses therapy of corticosteroids vs low-dose of corticosteroids and the development of complications. The primary endpoint was all-cause in-hospital mortality according to use of corticosteroids megadoses.

RESULTS

Of a total of 14,921 patients, corticosteroids were used in 5,262 (35.3%). Of them, 2,216 (46%) specifically received megadoses. Age was a factor that differed between those who received megadoses therapy versus those who did not in a significant manner (69 years [IQR 59-79] vs 73 years [IQR 61-83]; p < .001). Radiological and analytical findings showed a higher use of megadoses therapy among patients with an interstitial infiltrate and elevated inflammatory markers associated with COVID-19. In the univariate study it appears that steroid use is associated with increased mortality (OR 2.07 95% CI 1.91-2.24 p < .001) and megadose use with increased survival (OR 0.84 95% CI 0.75-0.96, p 0.011), but when adjusting for possible confounding factors, it is observed that the use of megadoses is also associated with higher mortality (OR 1.54, 95% CI 1.32-1.80; p < .001). There is no difference between megadoses and low-dose (p .298). Although, there are differences in the use of megadoses versus low-dose in terms of complications, mainly infectious, with fewer pneumonias and sepsis in the megadoses group (OR 0.82 95% CI 0.71-0.95; p < .001 and OR 0.80 95% CI 0.65-0.97; p < .001) respectively.

CONCLUSION

There is no difference in mortality with megadoses versus low-dose, but there is a lower incidence of infectious complications with glucocorticoid megadoses.

Outcome of low-dose prednisolone use for the induction of remission in lupus nephritis patients

OBJECTIVES

This study aimed to compare the efficacy of low-dose prednisolone with conventional high-dose regimen in proliferative lupus nephritis (LN) for remission.

METHODS

This open-label randomized clinical trial was conducted in the Department of Rheumatology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. A total of 32 LN patients were randomized into low-dose (experimental) and high-dose (control) groups. All subjects received standard dose of intravenous (I/V) methylprednisolone and pulse I/V cyclophosphamide. Oral prednisolone, 0.5 mg/kg/d and 1 mg/kg/d were given to experimental and control groups respectively for initially 4 weeks then tapered. The patients were followed for 24 weeks. The rates of renal remission (complete and partial) were assessed at 24 weeks. The disease activity, biochemical markers, and quality of life were evaluated at baseline and at 24 weeks.

RESULTS

Complete renal remission was achieved by 66.7% of patients in each group (P = .99). Renal remission (partial/complete) was achieved by 86.7% and 83.3% of patients in the prednisolone low-dose group and high-dose group respectively (P = .99). In between groups, no significant difference was observed in the improvement of active urinary sediments, serum creatinine level, anti-double-stranded DNA level, complements level, disease activity and Short Form-12 score. The prednisolone dose-related adverse events like cushingoid facies, abdominal stria, infections and serious adverse events like death occurred more in the high-dose prednisolone group.

CONCLUSIONS

It has been observed that low-dose prednisolone regimen may be effective in LN. Steroid dose-related side effects and rate of infections were lower in this group.

Intravenous pegylated liposomal prednisolone outperforms intramuscular methylprednisolone in treating rheumatoid arthritis flares: A randomized controlled clinical trial

Glucocorticoids (GCs) are potent anti-inflammatory drugs but their use is limited by systemic exposure leading to toxicity. Targeted GC delivery to sites of inflammation via encapsulation in long-circulating liposomes may improve the therapeutic index. We performed a randomized, double-blind, active-controlled, multi-center study in which intravenously (i.v.) administered pegylated liposomal prednisolone sodium phosphate (Nanocort) was compared to equipotent intramuscular (i.m.) methylprednisolone acetate (Depo-Medrol®; i.e. a current standards-of-care for treating flares in rheumatoid arthritis patients). We enrolled 172 patients with active arthritis who met all eligibility criteria, eventually resulting in 150 patients randomized in three groups: (1) Nanocort 75 mg i.v. infusion plus i.m. saline injection; (2) Nanocort 150 mg i.v. infusion plus i.m. saline injection; and (3) Depo-Medrol® 120 mg i.m. injection plus i.v. saline infusion. Dosing in each group occurred at baseline and on day 15 (week 2). Study visits occurred at week 1, 2, 3, 4, 6, 8 and 12, to assess both efficacy and safety. The primary endpoint was the "European League Against Rheumatism" (EULAR) responder rate at week 1. Safety was determined by the occurrence of adverse events during treatment and 12 weeks of follow-up. Treatment with Nanocort was found to be superior to Depo-Medrol® in terms of EULAR response at week 1, with p-values of 0.007 (good response) and 0.018 (moderate response). Treatments were well tolerated with a comparable pattern of adverse events in the three treatment groups. However, the Nanocort groups had a higher incidence of hypersensitivity reactions during liposome infusion. Our results show that liposomal Nanocort is more effective than Depo-Medrol® in treating patients with rheumatoid arthritis flares and has similar safety. This is the first clinical study in a large patient population showing that i.v. administered targeted drug delivery with a nanomedicine formulation improves the therapeutic index of glucocorticoids.

Long‐term glucocorticoids for rheumatoid arthritis

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To evaluate the benefits and harms of long‐term glucocorticoid therapy (longer than six months) for adults with rheumatoid arthritis.

The lupus nephritis management renaissance

Over the past year, and for the first time ever, the US Food and Drug Administration approved 2 drugs specifically for the treatment of lupus nephritis (LN). As the lupus community works toward understanding how to best use these new therapies, it is also an ideal time to begin to rethink the overall management strategy of LN. In addition to new drugs, this must include how to use kidney biopsies for management and not just diagnosis, how molecular technologies can be applied to interrogate biopsies and how such data can impact management, and how to incorporate LN biomarkers into management paradigms. Herein, we will review new developments in these areas of LN and put them into perspective for disease management now and in the future.

Inflammatory bowel disease and psoriasis: modernizing the multidisciplinary approach

Psoriasis and inflammatory bowel disease (IBD) are immune-mediated diseases occurring in barrier organs whose main task is to protect the organism from attack. These disorders are highly prevalent especially in northern Europe where psoriasis has a prevalence of around 3-4% and IBD around 0.3%. The prevalence of IBD in North America has been estimated at around 0.4%. The total incidence rates in northern Europe have been estimated at around 6 for Crohn's disease and 11 for ulcerative colitis per 100 000 person-years, compared with an incidence rate of around 280 per 100 000 person-years for psoriasis. Both diseases are less common in countries with a lower index of development. The rise in IBD appears to occur as populations adopt a westernized lifestyle, whereas psoriasis seems more stable and prevalence differences may derive more from variation in genetic susceptibility. The gut microbiota is clearly an important driver of IBD pathogenesis; in psoriasis, changes in gut and skin microbiota have been reported, but it is less clear whether and how these changes contribute to the pathogenesis. Large studies show that most identified genes are involved in the immune system. However, psoriasis and IBD are highly heterogeneous diseases and there is a need for more precise and deeper phenotyping to identify specific subgroups and their genetic, epigenetic and molecular signatures. Epigenetic modifications of DNA such as histone modifications, noncoding RNA effects on transcription and translation and DNA methylation are increasingly recognized as the mechanism underpinning much of the gene-environment interaction in the pathogenesis of both IBD and psoriasis. Our understanding of underlying pathogenetic mechanisms has deepened fundamentally over the past decades developing hand in hand with novel therapies targeting pathways and proinflammatory cytokines incriminated in disease. There is not only substantial overlap between psoriasis and IBD, but also there are differences with implication for therapy. In psoriasis, drugs targeting interleukin-23 and interleukin-17 have shown superior efficacy compared with anti-TNFs, whilst in IBD, drugs targeting interleukin-17 may be less beneficial. The therapeutic toolbox for psoriasis is impressive and is enlarging also for IBD. Still, there are unmet needs reflecting the heterogeneity of both diseases and there is a need for closer molecular diagnostics to allow for the development of precise therapeutics.

Long-Term Safety in HBsAg-Negative, HBcAb-Positive Patients with Rheumatic Diseases Receiving Maintained Steroid Therapy after Pulse Therapy

The risk of hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg)-negative, antibody to hepatitis B core antigen (anti-HBc)-positive patients after glucocorticoid (GC) pulse therapy remains unclear.

AIMS

Our study aimed to examine the safety of GC pulse therapy in HBsAg-negative, anti-HBc-positive rheumatic patients.

METHODS

Medical records of HBsAg-negative, anti-HBc-positive patients receiving GC pulse therapy to treat rheumatic diseases were reviewed. The primary outcome was HBV-associated hepatitis occurring within the first year after GC pulse therapy; the secondary outcome was HBsAg seroreversion occurring during the follow-up period.

RESULTS

We identified 5222 HBsAg-negative, anti-HBc-positive patients with rheumatic diseases who had attended Taichung Veterans General Hospital from October 2006 to December 2018. A total of 689 patients had received GC pulse therapy, with 424 patients being analyzed. Hepatitis was noted in 28 patients (6.6%) within the first year after GC pulse therapy, but none had been diagnosed as HBV-associated hepatitis. Three patients (0.7%) later developed HBsAg seroreversion, with a median interval of 97 months from the first episode of GC pulse therapy. These cases concurrently had maintained high dose oral prednisolone (≥20 mg prednisolone daily for over 4 weeks).

CONCLUSIONS

Amongst the HBsAg-negative, anti-HBc-positive rheumatic patients treated with GC pulse therapy, the risk of HBV-associated hepatitis within the first year was low. HBsAg seroreversion may have developed in the later stage, but only in those patients who had maintained high-dose oral steroid.

Rheumatoid arthritis-interstitial lung disease: manifestations and current concepts in pathogenesis and management

Rheumatoid arthritis (RA) is a systemic inflammatory disorder, with the most common extra-articular manifestation of RA being lung involvement. While essentially any of the lung compartments can be affected and manifest as interstitial lung disease (ILD), pleural effusion, cricoarytenoiditis, constrictive or follicular bronchiolitis, bronchiectasis, pulmonary vasculitis, and pulmonary hypertension, RA-ILD is a leading cause of death in patients with RA and is associated with significant morbidity and mortality. In this review, we focus on the common pulmonary manifestations of RA, RA-ILD and airway disease, and discuss evolving concepts in the pathogenesis of RA-associated pulmonary fibrosis, as well as therapeutic strategies, and have revised our previous review on the topic. A rational clinical approach for the diagnosis and management of RA-ILD, as well as an approach to patients with clinical worsening in the setting of treatment with disease-modifying agents, is included. Future directions for research and areas of unmet need in the realm of RA-associated lung disease are raised.

Treatment Update in Systemic Lupus Erythematous

The recent updates on treatment recommendations for the management of systemic lupus erythematous have provided greater clarity in the way existing anti-inflammatory and immunomodulatory drugs are used, in treating disease activity, preventing flares, and reducing irreversible organ damage and toxicity arising from the treatments themselves. Novel therapies will provide more options in the armamentarium for treating this complex disease, but ongoing studies are needed to improve understanding of the optimal treatment algorithm to maintain quality of life and improve survival for patients.

Glucose Metabolism in Burns-What Happens?

Severe burns represent an important challenge for patients and medical teams. They lead to profound metabolic alterations, trigger a systemic inflammatory response, crush the immune defense, impair the function of the heart, lungs, kidneys, liver, etc. The metabolism is shifted towards a hypermetabolic state, and this situation might persist for years after the burn, having deleterious consequences for the patient's health. Severely burned patients lack energy substrates and react in order to produce and maintain augmented levels of glucose, which is the fuel "ready to use" by cells. In this paper, we discuss biological substances that induce a hyperglycemic response, concur to insulin resistance, and determine cell disturbance after a severe burn. We also focus on the most effective agents that provide pharmacological modulations of the changes in glucose metabolism.

Management of glucocorticoid-induced osteoporosis

Long-term glucocorticoid (GC) therapy is frequently indicated to treat autoimmune and chronic inflammatory diseases in daily clinical practice. Two of the most devastating untoward effects are bone loss and fractures. Doses as low as 2.5 mg of prednisone for more than 3 months can impair bone integrity. Population at risk is defined based on the dose and duration of GC therapy and should be stratified according to FRAX (Fracture Risk Assessment Tool), major osteoporotic fracture, prior fractures, and bone mineral density values (BMD). General measures include to prescribe the lowest dose of GC to control the underlying disease for the shortest possible time, maintain adequate vitamin D levels and calcium intake, maintain mobility, and prescribe a bone acting agent in patients at high risk of fracture. These agents include oral and intravenous bisphosphonates, denosumab, and teriparatide.

[Effectiveness of glucocorticoids in patients hospitalized for severe SARS-CoV-2 pneumonia]

INTRODUCTION

Several studies have reported the beneficial effect of glucocorticoids in the treatment of cytokine storm that occurs in patients with severe COVID-19. Various glucocorticoids regimens have been proposed.

METHODS

Retrospective observational study that includes patients with severe SARS-CoV-2 pneumonia and compares admission to an Intensive Care Unit (ICU) or death during hospitalization in three groups of patients: no glucocorticoids treatment, use of glucocorticoids doses equivalent to less than 250mg of prednisone daily and use of equivalent doses greater than or equal to 250mg of prednisone daily. Multivariate analysis was performed using logistic regression, using the propensity index as a covariant.

RESULTS

Of the 259 patients enrolled in the study, 67 (25.9%) had an unfavorable evolution, dying or requiring ICU admission. Comparative analyzes between different glucocorticoids treatments and the association with ICU admission or death were: glucocorticoids treatment (any dose) versus no glucocorticoids treatment (OR: 0.71 [0.30-1.66]), treatment with glucocorticoids (≥250mg prednisone daily) versus no glucocorticoids treatment (OR: 0.35 [0.11-1.08]) and glucocorticoids treatment (≥250mg prednisone daily) versus patients with glucocorticoids doses <250mg prednisone daily or without glucocorticoids treatment (OR: 0.30 [0.10-0.88]).

CONCLUSION

The results of this study show that patients with severe SARS-CoV-2 pneumonia treated with glucocorticoids pulses with equivalent doses of prednisone greater than or equal to 250mg have a more favorable evolution (less mortality and less admission to ICU).

Should we use glucocorticoid in Early Rheumatoid Arthritis?: Results at 5 years from the ERA UCLouvain Brussels cohort

OBJECTIVES

To evaluate the proportion of patients with ERA who have initiated or not GC, to analyse the baseline characteristics, and to assess the clinical benefit and side effects of GC during 5 years of follow-up.

METHODS

We included patients with ERA from the UCLouvain Brussels cohort who met the ACR/EULAR 2010 classification criteria and were naïve to cDMARDs. We retrospectively collected patient characteristics prior to the introduction of cDMARDs with or without GC. Efficiency and serious adverse events were analysed at 6, 12, 36 and 60 months.

RESULTS

Data from 474 eligible ERA patients were collected. 180 patients initiated GC compared with 294 who did not.At baseline, the increased CRP is the main factor that favors the initiation of GC followed by smoking, absence of ACPA, prescription of methotrexate as a monotherapy and age.5 years follow-up of DAS28-CRP, HAQ or VAS pain values did not differ between the two groups.We also analysed a subgroup of 139 patients who received >1 g of prednisolone during the 5 years period. We confirmed the same baseline differences and observed in addition more males and higher DAS-28CRP values. During the 5 years follow up, DAS-28CRP, VAS pain and HAQ remained significantly higher in this subgroup. More severe infections were also reported.

CONCLUSION

In our ERA cohort, the initiation of GC treatment does not bring additional benefit for the short and long-term control of the disease. GC was more prescribed in seronegative RA patients with a higher level of inflammation.

The Use of Glucocorticoids in Lupus Nephritis: New Pathways for an Old Drug

Glucocorticoids therapy has greatly improved the outcome of lupus nephritis patients. Since their discovery, their adverse effects have counterbalanced their beneficial anti-inflammatory effects. Glucocorticoids exert their effects through both genomic and non-genomic pathways. Differential activation of these pathways is clinically relevant in terms of benefit and adverse effects. Ongoing aims in lupus nephritis treatment development focus on a better use of glucocorticoids combined with immunosuppressant drugs and biologics. Newer regimens aim to decrease the peak glucocorticoid dose, allow a rapid glucocorticoid tapering, and intend to control disease activity with a lower cumulative glucocorticoid exposure. In this review we discuss the mechanisms, adverse effects and recent strategies to limit glucocorticoid exposure without compromising treatment efficacy.

Treating systemic lupus erythematosus in the 21st century: new drugs and new perspectives on old drugs

Besides treating acute flares, the management of SLE should aim at preventing organ damage accrual and drug-associated harms, improving health-related quality of life and prolonging survival. At present, therapy is based on combinations of antimalarials (mainly HCQ), considered the backbone of SLE treatment, glucocorticoids and immunosuppressive drugs. However, these regimens are not universally effective and a substantial degree of damage can be caused by exposure to glucocorticoids. In this review we provide a critical appraisal of the efficacy and safety of available treatments as well as a brief discussion of potentially novel compounds in patients with SLE. We emphasize the use of methylprednisolone pulses for moderate–severe flares, followed by low–moderate doses of oral prednisone with quick tapering to maintenance doses of ≤5 mg/day, as well as the prompt institution of immunosuppressive drugs in the setting of severe disease but also as steroid-sparing agents. Indications for the use of biologic agents, namely belimumab and rituximab, in refractory or organ-threatening disease are also presented. We conclude by proposing evidence- and experience-based treatment strategies tailored to the clinical scenario and prevailing organ involvement that can aid clinicians in managing this complex disease.

Possible value of galectin-3 on follow-up of cardiac remodeling during glucocorticoid treatment

Glucocorticoids are among the most prescribed drugs globally due to their potent anti-inflammatory and immunosuppressive properties. Although they have positive effects on the treatment of various disease states; long-term administration is associated with high blood pressure, insulin resistance, and susceptibility to type 2 diabetes. The heart attempts to cope with increased blood pressure and a decrease in glucose utilization by developing pathological cardiac remodeling. However, in this process, cardiac fibrosis formation and deterioration in heart structure and functions occur. Galectin-3, a member of the β-galactoside binding lectins, is consistently associated with inflammation and fibrosis in the pathogenesis of various disease states including insulin resistance and heart failure. Galectin-3 expression is markedly increased in activated macrophages and a subset of activated fibroblasts and vascular cells. Also, failing and remodeling myocardium show increased Gal-3 expression and elevated Gal-3 levels are related to heart failure severity and prognosis. Furthermore, Gal-3-related pathways are recently suggested as therapeutic targets both pharmacologically and genetically to increase insulin sensitivity in vivo. The objective of this review is to provide a summary of our current understanding of the role of glucocorticoid-associated insulin resistance, which is important for some cardiac events, and the potential role of galectin in this pathophysiological process.

Intravenous methylprednisolone pulse as a treatment for hospitalised severe COVID-19 patients: results from a randomised controlled clinical trial

Introduction

There are no determined treatment agents for severe COVID-19. It is suggested that methylprednisolone, as an immunosuppressive treatment, can reduce the inflammation of the respiratory system in COVID-19 patients.

Methods

We conducted a single-blind, randomised controlled clinical trial involving severe hospitalised patients with confirmed COVID-19 at the early pulmonary phase of the illness in Iran. The patients were randomly allocated in a 1:1 ratio by the block randomisation method to receive standard care with methylprednisolone pulse (intravenous injection, 250 mg·day⁻¹ for 3 days) or standard care alone. The study end-point was the time of clinical improvement or death, whichever came first. Primary and safety analysis was done in the intention-to-treat (ITT) population.

Results

68 eligible patients underwent randomisation (34 patients in each group) from April 20, 2020 to June 20, 2020. In the standard care group, six patients received corticosteroids by the attending physician before the treatment and were excluded from the overall analysis. The percentage of improved patients was higher in the methylprednisolone group than in the standard care group (94.1% versus 57.1%) and the mortality rate was significantly lower in the methylprednisolone group (5.9% versus 42.9%; p<0.001). We demonstrated that patients in the methylprednisolone group had a significantly increased survival time compared with patients in the standard care group (log-rank test: p<0.001; hazard ratio 0.293, 95% CI 0.154–0.556). Two patients (5.8%) in the methylprednisolone group and two patients (7.1%) in the standard care group showed severe adverse events between initiation of treatment and the end of the study.

Conclusions

Our results suggest that methylprednisolone pulse could be an efficient therapeutic agent for hospitalised severe COVID-19 patients at the pulmonary phase.

This study showed that methylprednisolone pulse administration at the beginning of the early pulmonary phase of illness decreased the mortality rate and improved pulmonary involvement, oxygen saturation and inflammatory markers in COVID-19 patientshttps://bit.ly/3hik4JB

Dexamethasone Sodium Phosphate Loaded Modified Cyclodextrin Based Nanoparticles: An Efficient Treatment for Rheumatoid Arthritis

The main aim of the current research was to develop a modified cyclodextrin based nanoparticulate drug delivery system to deliver dexamethasone sodium phosphate (DSP) for the treatment of rheumatoid arthritis (RA). DSP is a glucocorticoid (GC), and its limited application in RA therapy due to poor pharmacokinetics and its severe associated side effects. DSP loaded hydrophobically modified cyclodextrin based nanoparticles (DSP-NPs) prepared by a double emulsion solvent evaporation method. The nanoparticle size was <120 nm, good entrapment efficiency and excellent stability were obtained. TEM study showed that nanoparticles were perfectly spherical shape. The in-vitro drug release from nanoparticle follows the non-Fickian diffusion mechanism. The pharmacokinetic profile of DSP after encapsulation showing the 2.3-fold increase in AUC and extended mean residence time, which increases the chances of nanoparticles to extravasate into the site of inflammation by the EPR effect. The pharmacodynamic studies in the Adjuvant-induced Arthritis (AIA) rat model showing a significant reduction in arthritic score, paw thickness, and inflammatory cytokine level in serum. Adverse effects evaluation studies demonstrate a significant reduction in the associated undesirable effects on body weight, blood glucose level, renal impairment, and hematological abnormalities compared to marketed formulation. These results suggest that DSP-NPs can be used as an efficient therapy for RA.

Second week methyl-prednisolone pulses improve prognosis in patients with severe coronavirus disease 2019 pneumonia: An observational comparative study using routine care data

Objective

To analyze the effects of a short course of methyl-prednisolone pulses (MP) during the second week of disease (week-2) in patients with severe coronavirus disease 2019 (COVID-19) pneumonia.

Methods

Comparative observational study using data collected from routine care at Hospital Universitario Cruces, Barakaldo, Bizkaia, Spain in patients with COVID-19 pneumonia. We compared patients who received week-2-MP (125–250 mg/d x3) with those who did not, with the end-points time to death and time to death or endotracheal intubation.

Results

We included 242 patients with COVID-19 pneumonia and elevated inflammatory markers at admission. Sixty-one patients (25%) received week-2-MP. Twenty-two patients (9%) died and 31 (12.8%) suffered death or intubation. The adjusted HRs for death and death or intubation for patients in the week-2-MP group were 0.35 (95%CI 0.11 to 1.06, p = 0.064) and 0.33 (95%CI 0.13 to 0.84, p = 0.020), respectively. These differences were specifically seen in the subcohort of patients with a SpO2/FiO2 at day 7 lower than 353 (adjusted HR 0.31, 95% CI 0.08 to 1.12, p = 0.073 and HR 0.34, 95%CI 0.12 to 0.94, p = 0.038, respectively) but not in patients with higher SpO2/FiO2. Patients receiving out-of-week-2-MP, non-pulse glucocorticoids or no glucocorticoids had an increased adjusted risk for both outcomes compared with week-2-MP group: HR 5.04 (95% CI 0.91–27.86), HR 10.09 (95% CI 2.14–47.50), HR 4.14 (95% CI 0.81–21.23), respectively, for death; HR 7.38 (95% CI 1.86–29.29), HR 13.71 (95% CI 3.76–50.07), HR 3.58 (95% CI 0.89–14.32), respectively, for death or intubation. These differences were significant only in the subgroup with low SpO2/FiO2.

Conclusions

Week-2-MP are effective in improving the prognosis of patients with COVID-19 pneumonia with features of inflammatory activity and respiratory deterioration entering the second week of disease. The recognition of this high-risk population should prompt early use of MP at this point.

Methylprednisolone pulse therapy: An alternative management of severe COVID-19

We present two cases of severe COVID-19 that were rejected by medical institutions. The management of the disease was done at home with methylprednisolone (MP) pulse therapy for three days. This resulted in a favorable evolution and resolution of most symptoms. COVID-19 infection presents as asymptomatic disease, non-severe symptomatic disease, and severe respiratory inflammatory disease. The first two forms are dependent on viral response and a “cytokine storm” is responsible for the progression into severe disease. Glucocorticoids (GC) reduce inflammation by different mechanism depending of their concentration. Pulses lead to overall apoptosis of immune cells. Studies using pulse MP as treatment for SARS-CoV-1 showed clinical improvement and decreased incidence of ARDS compared with patients who received low dose steroid treatment. Inhibition of excessive inflammation through timely administration of GC in the early stage of inflammatory cytokine storm effectively prevents the occurrence of ARDS.

Rheumatologic Medication Use During Pregnancy

Chronic rheumatic diseases often occur in women of reproductive age, and the effect rheumatic disease has on pregnancy varies depending on the condition. Medical management of rheumatic diseases during pregnancy may prevent joint or organ damage and minimize the adverse effects of the disease itself on pregnancy outcomes. Each patient requires individual assessment to control disease activity while minimizing or avoiding medications with potential maternal or fetal toxicity. An open discussion with shared decision making between patients, obstetricians, rheumatologists, and pharmacists is imperative to create an individualized treatment plan that meets patients' goals. This article will review the current literature for use of disease modifying antirheumatic drugs and biologics during pregnancy and lactation, providing health care professionals with the most up-to-date information available.

Use of glucocorticoids in the management of immunotherapy-related adverse effects

Immune checkpoint inhibitors (ICIs) activate host antitumor immunity to kill tumor cells. However, ICI therapy may be accompanied by a series of immunotherapy‐related adverse effects (irAEs) caused by activated autoreactive T cells. Glucocorticoids are the mainstream therapy for irAEs. However, the usage, dosage and course of treatment of irAEs with glucocorticoids differs from those used in classic autoimmune diseases. Furthermore, the long‐term use of large doses of glucocorticoids may cause serious adverse effects. In this article, the mechanism, dosage forms, adverse effects and management of glucocorticoids are described in detail, providing references and suggestions for oncologists to use glucocorticoids in the treatment of irAEs.

Glucocorticoids are the mainstream therapy for irAEs. We described the mechanism, dosage forms, adverse effects and management of glucocorticoids. We aimed to provide references and suggestions for oncologists to use glucocorticoids in the proper treatment of irAEs.

Glucocorticoids in Systemic Lupus Erythematosus. Ten Questions and Some Issues

Since the discovery of glucocorticoids (GCs), their important anti-inflammatory effect, rapid mechanism of action, low cost, and accessibility have made them one of the mainstays of treatment for Systemic lupus erythematosus (SLE). Although their use has allowed controlling the disease and reducing acute mortality in severe conditions, the implementation of a scheme based on high doses for long periods has inevitably been accompanied by an increase in adverse effects and infections, including long-term damage. The objective of this review is to answer some important questions that may arise from its use in daily clinical practice, and to propose a paradigm based on the use of methylprednisolone pulses followed by medium-low doses and a rapid decrease of prednisone.

Seventy years after Hench’s Nobel prize: revisiting the use of glucocorticoids in systemic lupus erythematosus

In 1950, Hench, Kendall and Reichstein were awarded with the Nobel Prize in Physiology and Medicine for the isolation and first therapeutic use of glucocorticoids. Since then, they have become one of the main agents in the treatment of systemic lupus erythematosus (SLE). The use of high-dose oral glucocorticoids (usually 1 mg/kg/day of prednisone equivalent) have become the rule for treating moderate to severe lupus activity. In addition, tapering schemes have not been well defined, all this leading to prolonged exposures to potentially damaging amounts of glucocorticoids. Several studies have shown that glucocorticoids are a major cause of toxicity in SLE in a dose-dependent manner, with prolonged doses greater than 7.5 mg/day being associated with damage accrual. Thus, there is an urgent need for different therapeutic schedules that can achieve a rapid and durable control of lupus activity while reducing the many unwanted effects of glucocorticoids. Recent data show that pulses of methyl-prednisolone are an effective first-line therapy to treat lupus flares (not only severe ones) without major short or long-term toxicity and allowing a reduction in oral prednisone doses. Universal use of hydroxychloroquine – always recommended, infrequently accomplished – and early therapy with immunosuppressive drugs also help control SLE and reduce prednisone load. Results from observational studies confirm the more rapid achievement of remission and the reduction of long-term damage using these combination schedules with reduced prednisone doses. Seventy years after their first therapeutic use, we are learning to use glucocorticoids in a more efficient and safe manner.

Glucocorticoids in rheumatoid arthritis: the silent companion in the therapeutic strategy

INTRODUCTION

Glucocorticoids (GCs) are key actors in RA management, despite the increasing number of available drugs. In fact, due to their efficacy and safety, the combination therapy between GCs and conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) is still recommended in the early phase of RA treatment, because improving the long-term results.

AREAS COVERED

In this paper, we reviewed the role of GCs in RA management, focusing on mechanisms of action as well as the benefit/risk ratio of GCs and newer therapeutic formulations. Furthermore, we analyzed GCs DMARDs proprieties on disease activity and their long-term effects on radiographic damage. We designed a narrative review aimed to provide an overview concerning GCs in RA management.

EXPERT OPINION

A large amount of evidence supports the use of GCs in RA, especially in the earliest phases of the disease. Besides GCs symptomatic effects due to their strong anti-inflammatory effects, data from several randomized clinical trials have shown a substantial benefit of low-dose GCs in inhibiting the radiographic damage, thus highlighting GCs DMARDs properties. Besides their recognized role in the treatment of early RA, systematic monitoring of adverse events should be recommended to minimize GCs toxicity.
