A Rare Case of Cyclophosphamide-Induced Posterior Reversible Encephalopathy Syndrome in a Patient With Acute Lupus Nephritis Flare

Posterior reversible encephalopathy syndrome (PRES) is a syndrome encompassing both clinical and radiological manifestations with white matter vasogenic edema predominantly of the posterior and parietal lobes of the brain. It may accompany several medical conditions including immunosuppressive/cytotoxic drugs. We present a case of cyclophosphamide-induced PRES in a patient treated for acute lupus flare with biopsy-proven lupus nephritis. A 23-year-old African American female presented with non-specific symptoms over a six-month period on a medical background of systemic lupus erythematosus and biopsy-proven focal lupus nephritis class III on hydroxychloroquine, prednisone, and mycophenolate mofetil for which she was non-compliant. She was borderline hypertensive, tachycardic, saturating well on ambient air, and alert and oriented. Laboratory workup revealed electrolyte imbalance, elevated serum urea, creatinine, and B-type natriuretic peptide, low serum complements, and elevated double-stranded DNA (dsDNA) with negative lupus anticoagulant, anti-cardiolipin, and B2 glycoprotein antibody. Chest imaging revealed cardiomegaly with small pericardial effusion, left pleural effusion, and trace atelectasis, with no deep vein thrombosis on Doppler ultrasound. She was admitted to the intensive care unit for lupus flare with severe hyponatremia and was continued on mycophenolate mofetil, hydroxychloroquine, and prednisone 60 mg for induction therapy as well as intravenous fluids. Hyponatremia resolved, and blood pressure was controlled. She became fluid overloaded and anuric, with pulmonary edema and worsening hypoxic respiratory failure not responding to diuretic challenges. Daily hemodialysis was started, and she was intubated. Prednisone was tapered down, mycophenolate was switched to cyclophosphamide/mesna. She became agitated, restless, and confused, with waxing and waning consciousness and hallucinations. She was continued on bi-weekly cyclophosphamide for induction therapy. After the second dose of cyclophosphamide, her mentation worsened. Non-contrast MRI showed extensive bilateral cerebral and cerebella deep white matter high-intensity signals suggestive of PRES, which was new compared to one year prior. Cyclophosphamide was held and her mentation improved. She was successfully extubated and discharged to a rehabilitation center. The exact pathophysiological mechanism of PRES is not known. Endothelial damage and vasogenic edema have been hypothesized as possible mechanisms. Severe anemia, fluid overload, and renal failure are some of the causes of endothelial dysfunction and vasogenic edema with disruption of the blood-brain barrier, which were found in our patient, but repeated dosing of cyclophosphamide worsened her condition. Discontinuation of cyclophosphamide led to a significant improvement and complete reversal of her neurologic symptoms, implying that prompt recognition and management of PRES is vital to prevent permanent damage and even death in these patients.

Reactive infectious mucocutaneous eruption following COVID-19 in an adolescent boy: Case report and review of the literature

Reactive infectious mucocutaneous eruption (RIME) is a mucosal-predominant eruption that usually affects two or more mucosal sites. We present a case of RIME secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and provide a brief review of the literature with a focus on the natural history and response to treatment. This entity may require inpatient management and systemic corticosteroids for symptom control in the pediatric population.

Efficacy of two different dosages of prednisone for treatment of subacute thyroiditis: a single-centre, prospective, randomized, open-label, non-inferiority trial

INTRODUCTION

The study aimed to explore the efficacy and safety of low-dose (LD) and regular-dose (RD) prednisone (PDN) for the treatment of subacute thyroiditis (SAT).

MATERIAL AND METHODS

Patients were randomly allocated using the block randomization method to the 2 groups. The primary outcome was the time required for PDN treatment. Secondary outcomes included percentages of relapse, mean score for the Morisky Medication Adherence Scale-8© (MMAS-8), time required for symptoms to resolve, cumulative PDN dose (mg), and mean erythrocyte sedimentation rate (ESR) at 2 weeks and at baseline.

RESULTS

The study cohort included 77 patients, randomized 74 participants, and 68 completed the study. There was no significant difference in the treatment duration between the LD and RD groups (55.31 ± 14.05 vs. 61.25 ± 19.95 days, p = 0.053). The mean difference in the time required for PDN treatment between the LD and RD groups was -1.86 [95% confidence interval (CI) = -10.64 to 6.92] days, which was within the non-inferiority margin of 7 days. There was a significant difference in the mean score for MMAS-8 between the LD and RD groups (5.84 ± 0.88 vs. 5.33 ± 1.12, p = 0.031). Also, there was a significant difference in the cumulative PDN dose between the LD and RD groups (504.22 ± 236.86 vs. 1002.28 ± 309.86, p = 0.046). The ESR at 2 weeks was statistically significant compared to baseline values in both groups, with pre-treatment and post-treatment ESRs of 49.91 ± 24.95 and 17.91 ± 12.60/mm/h, (p < 0.0001) in the LD group and 65.08 ± 21.77 and 17.23 ± 13.61/mm/h (p < 0.0001) in the RD group.

CONCLUSION

Low-dose PDN therapy may be sufficient to achieve complete recovery and better outcomes for SAT. This study is registered with the Chinese Clinical Trial Registry (02/10/2021 ChiCTR2100051762).

Should dexamethasone alone or in combination be the initial steroid for adult ITP: Still a relevant question

Corticosteroids are used in first-line treatment in newly diagnosed immune thrombocytopenia. The goal of treatment is primarily to decrease autoantibody-mediated platelet clearance. Ideally initial treatment would not just increase the platelet count but also provide a long-term sustained remission. While many clinicians use prednisone (PDN) as their first choice of corticosteroid, others prefer dexamethasone. The controversy is the subject of debates. Short courses of higher-dose corticosteroids were first reported by the Andersen study in 1994. The study posited high-dose dexamethasone as a 'cure' for all ITP patients. Later, studies addressed the number of dexamethasone cycles, indications to repeat cycles and timing between cycles, with varied long-term results. The results with dexamethasone were compared to PDN in some studies: the four-day cycles of dexamethasone work faster in increasing platelet counts and appear to reduce the occurrence of severe adverse events. Therefore, it is probably a better option for patients with low platelet counts and bleeding diathesis; however, curative superiority, the initial reason to administer it, compared to PDN is not well demonstrated. Across the studies, treatment with high-dose dexamethasone seems to be safer, with lower incidence of all adverse events compared to PDN, which might be a reflection of shorter treatment duration and possibly also lower cumulative steroid dose. Dexamethasone in combination with rituximab in first-line treatment produced higher response rates with better long-term results compared to high-dose dexamethasone alone and is a particularly good option in younger women.

Update on cryptogenic organizing pneumonia

Cryptogenic organizing pneumonia (COP) is a form of idiopathic interstitial pneumonia that results from the pulmonary reaction to various unidentified injuries. Secondary organizing pneumonia is diagnosed when the triggering factor has been identified; it is mainly caused by infections, toxic substance exposure, drugs, connective tissue diseases, malignancies, autoimmune diseases, bone marrow, or organ transplantation, and radiotherapy. There has been an increase in the number of reports of drug-induced organizing pneumonia (OP). New biological therapies, interferon, monoclonal antibodies, anti-interleukin antibodies, and PD1/PDL-1 inhibitors may induce this specific pulmonary reaction. The classical form of COP is usually subacute and does not manifest as severe disease. Patients maintain sufficient respiratory function, and treatment with steroids is usually effective. Several specific forms of OP (e.g., the cicatricial variant or acute fibrinous type) have distinct clinical and histological features, require higher doses of immunosuppressive drugs, and have a worse prognosis. In the era of administering steroid-sparing therapies for the treatment of interstitial lung diseases, connective tissue dases, and other conditions, it is important to emphasize this type of therapy for patients with COP.

Dexamethasone versus prednisone/prednisolone in the management of pediatric patients with acute asthmatic exacerbations: a systematic review and meta-analysis

OBJECTIVE

Acute asthmatic exacerbation is a common condition for pediatric emergency visits. Recently, dexamethasone has increasingly been used as an alternative to prednisone. This study aimed to evaluate the safety and efficacy of dexamethasone (DEX) against prednisone/prednisolone (PRED) in managing pediatric patients with acute asthmatic exacerbation.

DATA SOURCES

Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles from their inception to August 2022 by two independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42022353462).

STUDY SELECTIONS

From 316 studies screened, seventeen studies met the eligibility criteria, with 5967 pediatric patients experiencing an asthma exacerbation requiring treatment with either DEX (n = 2865) or PRED (n = 3102). Baseline patient characteristics (age, sex, PRAM (pediatric respiratory assessment measure), previous corticosteroid and beta-agonist inhaler) were comparable between groups.

RESULTS

After treatment administration, the DEX group had fewer vomiting incidents (OR = 0.24, 95% CI: 0.11, 0.51, I² = 58%) and reduced noncompliance events (OR = 0.12, 95% CI: 0.04, 0.34, I² = 0%) when compared to the PRED group. Regarding emergency-department (ED)-related outcomes, there were no differences in hospital admission rates (OR = 0.83, 95% CI: 0.58, 1.19, I² = 15%), time spent in the ED (MD= -0.11 h, 95% CI: -0.52; 0.30, I² = 82%) or relapse occurrences (OR = 0.67, 95% CI: 0.30, 1.49, I² = 52%) between both groups.

CONCLUSION

Although there were no differences between the DEX and PRED groups in terms of hospital admission rates, time spent in the ED or relapse events, pediatric patients receiving DEX experienced lower noncompliance and vomiting rates.

Controversies in rheumatology: maintenance therapy with low-dose glucocorticoids in rheumatoid arthritis

Since the beginning of the use of glucocorticoids in clinical medicine, the risk-benefit ratio of these still very important drugs has been debated. There is no doubt that they produce many desirable therapeutic effects quickly and reliably. However, their potential to cause adverse effects, especially with prolonged use in high doses, limits their applicability. We discuss the arguments against and in favour of maintenance therapy with low-dose glucocorticoids in patients with RA, and present recent studies, assessments and conclusions on this question.

The association between platelet glycoprotein-specific antibodies and response to short-term high-dose dexamethasone with prednisone maintenance treatment in adult patients with primary immune thrombocytopenia

OBJECTIVE

The aim of the present study was to detect the association between platelet glycoprotein-specific autoantibodies and the patient response to short-term high-dose dexamethasone (HD-DXM) + prednisone maintenance treatment.

METHODS

The data from 112 adult patients newly diagnosed with ITP who were administered first-line HD-DXM + prednisone maintenance therapy between January 2016 and January 2021 were retrospectively analyzed.

RESULTS

A total of 72 patients positive for platelet glycoprotein-specific antibodies were enrolled in the antibody-positive group, and 40 patients not positive for platelet glycoprotein-specific antibodies were enrolled in the antibody-negative group. In the antibody-positive group, six platelet glycoprotein-specific antibody types were found: 41.67% of the patients were anti-GP IIb/IIIa-positive only, 5.56% were anti-GP Ib/IX-positive only, 5.56% were anti-P-selectin-positive only, 19.44% were anti-GP IIb/IIIa- and anti-GP Ib/IX-positive, 16.67% were anti-GP Ib/IX- and P-selectin-positive and 11.11% were positive for all three antibodies. There was no significant difference in the overall response rate between the antibody-positive group and the antibody-negative group (94.44 versus 80.00%, p = .221). However, the CR rate was significantly higher in the antibody-positive group than in the antibody-negative group (69.44% versus 40.00%, p = .032). The logistic regression analysis revealed that platelet glycoprotein-specific antibody positivity and age were two factors that could affect patient response.

CONCLUSIONS

The present study discovered that adult patients newly diagnosed with ITP who had positive platelet glycoprotein-specific antibody test results were likely to achieve a better response after treatment with HD-DXM + prednisone maintenance.

Clinical efficacy and safety of sirolimus in childhood-onset systemic lupus erythematosus in real world

To investigate the effectiveness and safety of sirolimus in childhood-onset systemic lupus erythematosus in a real world. This is a retrospective real world clinical study. All childhood-onset systemic lupus erythematosus patients treated with sirolimus in Children's Hospital of Hebei Province China were analyzed. They were treated with sirolimus and followed up regularly. The patients had systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score, levels of antidouble-stranded DNA antibody, complement components C3 and C4, 24-hour proteinuria and corticosteroid reduction were recorded at baseline and at 6, 12, and 18 months. Adverse events were also collected. Thirty-two patients were enrolled in the study. SLEDAI-2K were improved on all time-points (P < .05). Complement levels increased and the levels of antidouble-stranded DNA antibody decreased during treatment. The mean dose of prednisone tapered and achieved significant reduction after 12 months therapy (15.4 ± 5.8 mg/d to 4.8 ± 2.1 mg/d; P < .05). Sirolimus was well tolerated and only 5 patients (15.6%) experienced adverse events, all of which were classified as infections (2 bacterial infection and 3 viral infections). No deaths, severe infusion reactions, or hypersensitivity reactions were found. Sirolimus use was associated with a decrease in disease activity and ability to tolerate tapering of oral glucocorticoid dose with a favorable risk-benefit profile.

Is prednisone still a reasonable option in the treatment of withdrawal headache in patients with chronic migraine and medication overuse headache in the age of CGRP antibodies? A narrative review

OBJECTIVE

Along with the development of novel migraine therapies as the monoclonal antibodies against calcitonin gene-related peptide (CGRP) and its receptor, the question arises if the treatment of chronic migraine (CM) and medication overuse headache (MOH) must be reconsidered. Have previous therapeutic approaches, including glucocorticoids, lost their role in the management of this debilitating disorder? In this narrative review, we present an overview of the available treatment options in CM and MOH in light of CGRP antibodies as well as an evaluation of the role of glucocorticoids in withdrawal therapy.

BACKGROUND

Chronic migraine and medication overuse continues to be a difficult to treat condition. To date, potent treatment options are scarce and algorithms for advising patients with MOH are often still based on expert consensus rather than evidence-based medicine. For years and probably due to lack of effective alternatives, glucocorticoids have been used in MOH, especially to alleviate withdrawal symptoms caused by detoxification. Small case series report positive effects of steroids in this respective patient group; however, randomized controlled trials did not show a consistent benefit, although this may be due to methodological limitations. Because of these discrepancies, their role in MOH has been under debate ever since.

METHODS

We searched the electronic database PubMed for articles up to June 1, 2022 on the use of glucocorticoids in CM and MOH.

CONCLUSION

Despite popular use in clinical practice, there is currently still no scientific evidence for the efficacy of glucocorticoids in patients with CM and MOH. Treatment with monoclonal antibodies achieved high transition rates from medication overuse to non-overuse. However, further research is needed to evaluate the additional benefit of these new agents.

The Efficacy of Cyclophosphamide Combined with Prednisone in Membranous Nephropathy Patients with Different Cytochrome P450 2B6 Gene Polymorphisms and Analysis of Factors Influencing the Efficacy

OBJECTIVE

To investigate the efficacy of cyclophosphamide combined with prednisone in membranous nephropathy (MN) patients with different cytochrome P450 (CYP) 2B6 gene polymorphisms and explore the factors influencing the efficacy.

METHODS

We performed a prospective and interventional study including 153 outpatients diagnosed with membranous nephropathy from April 2020 to June 2020 in the Bayannur Hospital. Based on the results of CYP2B6 gene polymorphisms, patients were divided into CYP2B6*4 group (785A>G) with 93 cases and CYP2B6*5 group (1459C>T) with 60 cases, and all patients were treated with cyclophosphamide and prednisone. The efficacy of the two groups was compared, and the serum levels of antibody against thrombospondin type-1 domain-containing 7A (THSD7A-Ab), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and antibody against the M-type phospholipase A2 receptor (PLA2R-Ab) determined by the enzyme-linked immunosorbent method were analyzed in the two groups before and after treatment.

RESULTS

After the treatment with cyclophosphamide and prednisone, serum levels of THSD7A-Ab, 8-OHdG, and PLA2R-Ab were higher in the CYP2B6*4 group than those in the CYP2B6*5 group (All three P<0.001). The univariate Logistic regression analysis showed that CYP2B6*4 (OR = 1.727, 95% CI: 1.028-2.654. P=0.012), CYP2B6*5 (OR = 1.802, 95% CI: 1.179-2.752. P=0.031), THSD7A-Ab (OR = 1.832, 95% CI: 0.871-2.348. P=0.023), 8-OHdG (OR = 1.661, 95% CI: 1.123-2.231. P=0.009), PLA2R-Ab (OR = 1.649, 95% CI: 1.083-2.761. P=0.017) were independent influencing factors on the efficacy of MN. The multivariate Logistic regression analysis showed that CYP2B6*4 (OR = 2.009, 95% CI: 1.327-2.703. P<0.001), CYP2B6*5 (OR = 3.009, 95% CI: 1.467-5.231. P=0.005), THSD7A-Ab (OR = 1.396, 95% CI: 1.002-1.897. P=0.019), 8-OHdG (OR = 0.704, 95% CI: 0.591-0.742. P<0.001), PLA2R-Ab (OR = 2.761, 95% CI: 1.231-3.918. P=0.017) were independent factors influencing the efficacy of cyclophosphamide and prednisone on MN.

CONCLUSION

Cyclophosphamide combined with prednisone was effective in treating MN with different CYP2B6 gene polymorphisms. CYP2B6*4, CYP2B6*5, and serum levels of THSD7A-Ab, 8-OHdG, and PLA2R-Ab were independent influencing factors on the outcome of MN.

A Clinical Response-Adjusted Steroid Treatment Protocol for Children With Newly Diagnosed Idiopathic Nephrotic Syndrome

RATIONALE & OBJECTIVE

Prednisone protocols for children with idiopathic nephrotic syndrome (INS) are generally similar in dose and duration, despite wide variations in time to response. We assessed the feasibility of a novel clinical treatment protocol characterized by a shorter duration and lower cumulative dose for children with early clinical response.

STUDY DESIGN

Nonrandomized pilot clinical trial.

SETTING & PARTICIPANTS

The study population included 59 children with newly diagnosed INS treated between 2014 and 2019 who responded to treatment within 8 days.

INTERVENTION

The intervention group (n = 27) was treated with a response-adjusted protocol during which responders received an 8-week course of tapering doses of prednisone. The usual care group (n =32) was treated with the standard protocol (prednisone, 60 mg/m²/24 hours for 6 weeks, followed by 40 mg/m²/48 hours for 4 weeks, followed by a slow taper for a total of 24 weeks).

OUTCOME

Consent rate, cumulative prednisone dose, the development of frequently relapsing or steroid-dependent nephrotic syndrome (FRNS or SDNS, respectively), relapses per year, treatment with steroid-sparing therapies, and adverse effects of steroid therapy over 3 years of follow-up observation.

RESULTS

The consent rate was 88%. The mean cumulative steroid dose for the initial treatment was 70 mg/kg and 141 mg/kg (P < 0.001) in the intervention and usual care groups, respectively. None of the patients in the intervention group relapsed while on faster steroid taper down. The occurrence of FRNS and SDNS in the intervention group was not statistically different than in the usual care group, hazard ratios were 0.80 (95% CI, 0.37-1.73) and 0.61 (95% CI, 0.30-1.27), respectively. The proportions of relapse-free patients were similar (P = 0.5), and adverse steroid events did not differ between the groups.

LIMITATIONS

Lack of randomization and small sample size.

CONCLUSIONS

These findings demonstrate the feasibility of a shortened duration of steroid dosing for INS when patients demonstrate an initial clinical response to treatment. A larger study is needed to characterize the relative efficacy and toxicity of this novel treatment regimen.

The Clinical Effect of Steroids for Hearing Preservation in Cochlear Implantation: Conclusions Based on Three Cochlear Implant Systems and Two Administration Regimes

The main aim of this study was to assess the clinical effect of steroids (dexamethasone and prednisone) on hearing preservation in patients who underwent cochlear implantation with different cochlear implant systems (Oticon®, Advanced Bionics®, Med-El®). 147 adult patients met the inclusion criteria and were enrolled to the study and divided into three groups depending on the brand of cochlear implant they received and participated in all follow-up visits regularly. They were also randomly divided into three subgroups depending on the steroid administration regime: (1) intravenous dexamethasone (0.1 mg/kg body weight twice a day for three days); (2) combined intravenous and oral steroids (dexamethasone 0.1 mg/kg body weight twice a day plus prednisone 1 mg/kg weight once a day); and (3) no steroids (control group). The results were measured by pure tone audiometry (PTA) at three time points: (i) before implantation, (ii) at processor activation, and (iii) 12 months after activation. A hearing preservation (HP) figure was also calculated by comparing the preoperative results and the results after 12 months. Further measures collected were electrode impedance and hearing threshold in the non-operated ear. The highest HP measures (partial and complete) were obtained in the subgroups who were given steroids. Of the 102 patients given steroids, HP was partial or complete in 63 of them (62%). In comparison, partial or complete HP was achieved in only 15 patients out of 45 (33%) who were not given steroids. There were differences between the three cochlear implant groups, with the Med-El and Advanced Bionics groups performing better than the Oticon group (45% and 43% of the former two groups achieved partial or complete HP compared to 20% in the latter). Hearing thresholds in the non-operated ear were stable over 12 months. Generally, impedance was slightly lower in the 12 month follow-up in comparison with the activation period, with the exception of the Oticon group. (4) Conclusions: Pharmacological treatment with steroids in patients undergoing cochlear implantation helps to preserve residual hearing.

Remission and relapses of myasthenia gravis on long-term tacrolimus: a retrospective cross-sectional study of a Chinese cohort

Objective:

To identify the factors that predict the remission and relapses in myasthenia gravis (MG) patients improved by prednisone and tacrolimus treatment.

Methods:

A retrospective, observational cohort analysis of MG patients who achieved remission after receiving prednisone and tacrolimus were performed at Tongji Hospital. The main outcome measures were the time to remission, prednisone discontinuation, tacrolimus reduction–associated relapse, and treatment outcome.

Results:

After adding tacrolimus, 256 patients were able to achieve remission with a mean time to remission of 2.1 ± 1.4 months. After a median follow-up of 2.9 years, 167 patients (65.2%) discontinued prednisone, and 20 patients (7.8%) achieved complete stable remission. Moreover, 53 of the 109 patients who were tapering tacrolimus experienced relapses. In multivariable analysis, female sex, low tacrolimus concentrations, and quantitative myasthenia gravis (QMG) scores have a positive correlation with the time to remission; concomitant additional autoimmune disease (AID) and high anti-acetylcholine receptor antibody (AChR-ab) levels were significantly associated with low probabilities of prednisone discontinuation [odds ratio (OR) = 0.312–0.912, respectively]; rapid tacrolimus decrement speed (⩾0.76 mg/year) was an independent predictor for the development of relapse during tapering tacrolimus (OR = 5.662).

Conclusion:

Sex, tacrolimus concentrations, and QMG scores can be used as potential predictors of the time to remission in MG patients treated with tacrolimus and prednisone. Prednisone should be tapered slowly, especially in patients with additional AID or high serum titers of AChR-ab. To avoid symptoms recurrence, the dose of tacrolimus should reduce slowly, not exceeding 0.76 mg/year.

Urinary excretion profile of prednisolone and prednisone after rectal administration: significance in antidoping analysis

The rectal administration of glucocorticoids, as well as any injectable, and oral ones, is currently prohibited by the World Anti-Doping Agency when occurs "in competition". A reporting level of 100 ng/mL for prednisolone and 300 ng/mL for prednisone was established to discriminate the allowed and the prohibited administration. Here, the urinary excretion profiles of prednisone and prednisolone were evaluated in five volunteers in therapy with glucocorticoid-based rectal formulations containing prednisone or prednisolone caproate. The urinary levels of the excreted target compounds were determined by LC-MS/MS following the procedure validated and currently in use in our laboratory to detect and quantitate glucocorticoids in urine. Predictably, the excretion trend of the analytes of interest were generally comparable to those obtained after oral administration, even if the excretion profile showed a broad inter-individual variability, with the absorption rate and the systemic bioavailability after rectal administration being strongly influenced by the type of formulations (suppository or rectal cream, in our case) as well as the physiological conditions of the absorption area. Results showed that the target compounds were detectable for at least 30 hours after drug administration. After suppository administration, prednisolone levels reached the maximum after 3 hours from drug administration, and then dropped below the reporting level after 15-21 hours; prednisone reached the maximum after 3 hours from drug administration, and then dropped below the reporting level after 12-15 hours. After cream administration both prednisone and prednisolone levels remained in a concentration below the reporting level throughout the entire monitored period.

Prednisone and deflazacort in Duchenne muscular dystrophy: a patient perspective and plain language summary publication of the Cincinnati study

WHAT IS THIS SUMMARY ABOUT?

This is a summary of an article about the Cincinnati study, which was published in the Journal of Comparative Effectiveness Research in January 2020. The Cincinnati study reviewed data from 435 males with Duchenne muscular dystrophy, also known as DMD, who were treated at the Cincinnati Children's Hospital Medical Center. DMD is a rare disease that worsens over time. People with DMD experience inflammation in their muscles and muscle loss over time. They also experience bone problems such as an abnormally bent spine, also known as scoliosis, as well as heart and lung problems.

WHAT HAPPENED IN THE CINCINNATI STUDY?

Prednisone and deflazacort are steroids that help to reduce muscle inflammation and are used as treatments for DMD. The study researchers wanted to further understand the differences between using prednisone and deflazacort in males with DMD by reviewing data from past medical records of patients seen in clinics rather than in clinical studies. This is known as gathering real-world evidence. In the Cincinnati study, the researchers compared males with DMD who started taking prednisone as their first steroid treatment with males who started taking deflazacort as their first steroid treatment.

WHAT WERE THE RESULTS?

Overall, the researchers found that the participants who took deflazacort were able to walk until a later age before they needed to use a wheelchair, compared with those who took prednisone. They also had a lower risk of scoliosis and developed it at a later age.

WHAT DO THE RESULTS OF THE STUDY MEAN?

These results helped the researchers to learn more about the differences between how well prednisone and deflazacort work in males with DMD based on their medical records.

Comparing Deflazacort and Prednisone in Duchenne Muscular Dystrophy

Deflazacort and prednisone/prednisolone are the current standard of care for patients with Duchenne muscular dystrophy (DMD) based on evidence that they improve muscle strength, improve timed motor function, delay loss of ambulation, improve pulmonary function, reduce the need for scoliosis surgery, delay onset of cardiomyopathy, and increase survival. Both have been used off-label for many years (choice dependent on patient preference, cost, and geographic location) before FDA approval of deflazacort for DMD in 2017. In this review, we compare deflazacort and prednisone/prednisolone in terms of their key pharmacological features, relative efficacy, and safety profiles in patients with DMD. Differentiating features include lipid solubility, pharmacokinetics, changes in gene expression profiles, affinity for the mineralocorticoid receptor, and impact on glucose metabolism. Evidence from randomized clinical trials, prospective studies, meta-analyses, and post-hoc analyses suggests that patients receiving deflazacort experience similar or slower rates of functional decline compared with those receiving prednisone/prednisolone. Regarding side effects, weight gain and behavior side effects appear to be greater with prednisone/prednisolone than with deflazacort, whereas bone health, growth parameters, and cataracts appear worse with deflazacort.

Enhancing Prednisone-Based Arthritis Therapy with Targeted IL-27 Gene Delivery

Rheumatoid arthritis (RA) is a chronic autoimmune disease which is characterized primarily by synovial hyperplasia and accumulation of several types of immune infiltrates that promote progressive destruction of the articular structure. Glucocorticoids are often prescribed to treat RA because of their strong anti-inflammatory and immunosuppressive effects. However, their application must be limited to the short-term due to a risk of adverse events. In the present study, we examined the potential combination of low-dose prednisone with gene delivery of an agent of promising and complementary effectiveness in RA, interleukin (IL)-27. IL-27 has been shown to have anti-inflammatory potential, while also acting as an effective bone-normalization agent in prior reports. The present report examined a version of IL-27 targeted at the C-terminus with a short ‘peptide L’ (pepL, LSLITRL) that binds the interleukin 6 receptor α (IL-6Rα) upregulated during inflammation. By focusing on this targeted form, IL-27pepL or 27pL, we examined whether the anti-inflammatory potential of prednisone (at a relatively low dose and short duration) could be further enhanced in the presence of 27pL as a therapy adjuvant. Our results indicate that 27pL represents a novel tool for use as an adjuvant with current therapeutics, such as prednisone, against inflammatory conditions.

Ruxolitinib combined with prednisone, thalidomide and danazol in patients with myelofibrosis: Results of a pilot study

Ruxolitinib is a safe and effective therapy of myeloproliferative neoplasm-associated (MPN) myelofibrosis. However, often there are dose reductions and/or therapy interruptions because of therapy-related adverse events (AEs), especially anemia and thrombocytopenia. We previously reported combined therapy with prednisone, thalidomide and danazol (PTD) reversed anemia and thrombocytopenia in people with MPN-associated myelofibrosis. We wondered whether adding PTD to ruxolitinib might mitigate the hematologic AEs and thereby avoid the dose reduction of ruxolitinib and improve the efficacy. To test this hypothesis, we conducted a baseline hemoglobin and platelet concentration assignment prospective observational study in 72 patients comparing 3-month dose adjustment and efficacy of ruxolitinib with (N = 53, the study group) or without (N = 19, the control group) PTD. According to the platelet counts, the median daily ruxolitinib doses in the study group increased from 30 to 40 mg by week 12, whereas in the control group it remained at 30 mg (p = 0.019). In the study group 35 patients had a hemoglobin increase ≥10 g/L compared with no patient receiving ruxolitinib only (p < 0.001). Platelet increases >100 × 10E+9/L were seen in 56.6% and 5.3% of patients in the two groups, respectively (p < 0.001). In patients with anemia and thrombocytopenia, 18 patients in the study group had an anemia response at week 12 and 12 had a platelet increase of ≥50 × 10E+9/L. No patient in the control group achieved either response (p < 0.001 and p = 0.078). The study group had a more spleen response than the control group (p = 0.046). Peripheral edema and transaminase elevation were the main nonhematologic AEs of PTD. These AEs can be alleviated by adjusting the danazol dose. In conclusion, adding PTD to ruxolitinib improved ruxolitinib-associated anemia and thrombocytopenia, and resulted in a higher ruxolitinib dose.

Glucocorticoid prevents CD138 expression in T cells of autoimmune MRL/lpr mice

CD138⁺ T cells, the majority of which are CD4 and CD8 double-negative (DN) T cells, contribute to the production of anti-dsDNA antibodies in a CD4 receptor-dependent way to promote the development of systemic lupus erythematosus (SLE). Accumulation of CD138⁺ T cells in the spleen of MRL/lpr mice was significantly reduced by prednisone. Reduced expression of CD138 in DN T cells induced by prednisone treatment alleviated the accumulation of DN T cells in MRL/lpr mice. The frequency of CD138⁺ cells in CD4⁺ T cells of prednisone-treated MRL/lpr mice was also significantly reduced, which subsequently contributed to reduced production of anti-dsDNA antibody in the prednisone-treated MRL/lpr mice. Additionally, prednisone significantly reduced serum IgG and IgG subsets and simultaneously increased IgM secretion in serum. This suggested that glucocorticoids played a protective role during SLE treatment in MRL/lpr mice by promoting the production of IgM. The present study provides new insights into the mechanism of glucocorticoid for the treatment of SLE.

Nutritional recommendations for patients undergoing prolonged glucocorticoid therapy

Glucocorticoid (GC) therapy is a common treatment used in rheumatic and autoimmune diseases, owing to its anti-inflammatory and immunosuppressive effects. However, GC therapy can also induce a number of adverse effects, including muscle and bone loss, hypertension, metabolic perturbations and increased visceral adiposity. We review available evidence in this area and provide nutritional recommendations that might ameliorate these adverse effects. Briefly, optimizing calcium, vitamin D, sodium and protein intake and increasing consumption of unprocessed and minimally processed foods, while decreasing the consumption of ultra-processed foods, might counteract some of the specific challenges faced by these patients. Importantly, we identify a dearth of empirical data on how nutritional intervention might impact health-related outcomes in this population. Further research is required to investigate the clinical and therapeutic efficacy of these theory-based recommendations.

Quality of Life in Myasthenia Gravis and Correlation of MG-QOL15 with Other Functional Scales

Health-related quality of life (HRQOL) in myasthenia gravis (MG) is frequently decreased. Further, there are many validated clinical scales and questionnaires to evaluate the clinical status in MG. We aimed to determine if there was an improvement in HRQOL following an intensive treatment for MG, identify which demographic and clinical features influenced patients’ HRQOL, and investigate if the questionnaire MG-QOL15 correlated with other evaluation scales. We recruited 45 patients with generalised MG who were starting immunomodulatory treatment with intravenous immunoglobulins and prednisone for the first time. At each visit, we administered several validated scales for MG. The mean MG-QOL15 score improved significantly at 4 and 6 weeks of the study. Additionally, the MG-QOL15 score correlated strong with the Myasthenia Gravis-Activities of Daily Living (MG-ADL) and the Neuro-QOL Fatigue and weakest with the Quantitative Myasthenia Gravis Scoring System (QMG). The QMG score prior to study enrolment was associated with HRQOL. We observed that HRQOL in MG improved after receiving an intensive immunomodulatory treatment and achieving better control of the symptoms. The questionnaire MG-QOL15 correlated positively with other clinical measures. As MG is a fluctuating condition, and some symptoms are difficult to examine, we direct physicians toward the use of scales and questionnaires composed of items perceived by the patient.
