Methylprednisolone for Heart Surgery in Infants - A Randomized, Controlled Trial.

BACKGROUND: Although perioperative prophylactic glucocorticoids have been used for decades, whether they improve outcomes in infants after heart surgery with cardiopulmonary bypass is unknown. METHODS: We conducted a multicenter, prospective, randomized, placebo-controlled, registry-based trial involving infants (<1 year of age) undergoing heart surgery with cardiopulmonary bypass at 24 sites participating in the Society of Thoracic Surgeons Congenital Heart Surgery Database. Registry data were used in the evaluation of outcomes. The infants were randomly assigned to receive prophylactic methylprednisolone (30 mg per kilogram of body weight) or placebo, which was administered into the cardiopulmonary-bypass pump-priming fluid. The primary end point was a ranked composite of death, heart transplantation, or any of 13 major complications. Patients without any of these events were assigned a ranked outcome based on postoperative length of stay. In the primary analysis, the ranked outcomes were compared between the trial groups with the use of odds ratios adjusted for prespecified risk factors. Secondary analyses included an unadjusted odds ratio, a win ratio, and safety outcomes. RESULTS: A total of 1263 infants underwent randomization, of whom 1200 received either methylprednisolone (599 infants) or placebo (601 infants). The likelihood of a worse outcome did not differ significantly between the methylprednisolone group and the placebo group (adjusted odds ratio, 0.86; 95% confidence interval [CI], 0.71 to 1.05; P = 0.14). Secondary analyses (unadjusted for risk factors) showed an odds ratio for a worse outcome of 0.82 (95% CI, 0.67 to 1.00) and a win ratio of 1.15 (95% CI, 1.00 to 1.32) in the methylprednisolone group as compared with the placebo group, findings suggestive of a benefit with methylprednisolone; however, patients in the methylprednisolone group were more likely than those in the placebo group to receive postoperative insulin for hyperglycemia (19.0% vs. 6.7%, P<0.001). CONCLUSIONS: Among infants undergoing surgery with cardiopulmonary bypass, prophylactic use of methylprednisolone did not significantly reduce the likelihood of a worse outcome in an adjusted analysis and was associated with postoperative development of hyperglycemia warranting insulin in a higher percentage of infants than placebo.

HIF-1α in cartilage homeostasis, apoptosis, and glycolysis in mice with steroid-induced osteonecrosis of the femoral head.

With the prevalence of coronavirus disease 2019, the administration of glucocorticoids (GCs) has become more widespread. Treatment with high-dose GCs leads to a variety of problems, of which steroid-induced osteonecrosis of the femoral head (SONFH) is the most concerning. Since hypoxia-inducible factor 1α (HIF-1α) is a key factor in cartilage development and homeostasis, it may play an important role in the development of SONFH. In this study, SONFH models were established using methylprednisolone (MPS) in mouse and its proliferating chondrocytes to investigate the role of HIF-1α in cartilage differentiation, extracellular matrix (ECM) homeostasis, apoptosis and glycolysis in SONFH mice. The results showed that MPS successfully induced SONFH in vivo and vitro, and MPS-treated cartilage and chondrocytes demonstrated disturbed ECM homeostasis, significantly increased chondrocyte apoptosis rate and glycolysis level. However, compared with normal mice, not only the expression of genes related to collagens and glycolysis, but also chondrocyte apoptosis did not demonstrate significant differences in mice co-treated with MPS and HIF-1α inhibitor. And the effects observed in HIF-1α activator-treated chondrocytes were similar to those induced by MPS. And HIF-1α degraded collagens in cartilage by upregulating its downstream target genes matrix metalloproteinases. The results of activator/inhibitor of endoplasmic reticulum stress (ERS) pathway revealed that the high apoptosis rate induced by MPS was related to the ERS pathway, which was also affected by HIF-1α. Furthermore, HIF-1α affected glucose metabolism in cartilage by increasing the expression of glycolysis-related genes. In conclusion, HIF-1α plays a vital role in the pathogenesis of SONFH by regulating ECM homeostasis, chondrocyte apoptosis, and glycolysis.

Glucocorticoid-induced adrenal insufficiency after therapy with intravenous methylprednisolone in patients with moderate-to-severe and active Graves' orbitopathy: assessment with a low-dose corticotropin test.

PURPOSE: We aimed to assess adrenal function following treatment of moderate-to-severe and active Graves' orbitopathy (GO) with intravenous methylprednisolone (IVMP) in weekly pulses in a cumulative dose of 4.5 or 7.5 g. We evaluated the impact of IVMP pulses on adrenal reserve using a low-dose (1 µg) ACTH stimulation test (LDT) for the first time. METHODS: In this prospective study we evaluated adrenal function in 21 patients with moderate-to-severe and active GO treated with 12 weekly IVMP pulses according to the European Group on Graves' Orbitopathy (EUGOGO) recommendations. We assessed serum cortisol, plasma adrenocorticotropic hormone (ACTH), and dehydroepiandrosterone sulfate (DHEA-S) levels before the 1st and 12th IVMP pulse. We performed dynamic testing using LDT before the 12th IVMP pulse in all patients. In those who failed LDT, adrenal function was reassessed with LDT and the overnight metyrapone test after 4-7 weeks. RESULTS: Two patients failed to achieve serum cortisol levels ≥ 18.1 µg/dL at 30 and 60 min in LDT and were diagnosed with glucocorticoid-induced adrenal insufficiency (GC-induced AI). They were recommended to take hydrocortisone in situations of acute stress. Both patients were reassessed within 4-7 weeks after treatment cessation and showed an adequate response in LDT and overnight metyrapone test. We observed a statistically significant decrease in DHEA-S levels (p = 0.004) before the 12th IVMP pulse compared to baseline in all patients. CONCLUSION: For the first time, our research shows that administering IVMP in 12 weekly pulses can result in GC-induced AI. We suggest that patients should undergo careful evaluation for GC-induced AI, including LDT, after therapy with IVMP according to EUGOGO guidelines. Screening for altered adrenal reserve could prevent life-threatening complications, particularly during acute stress situations.

Comparison of side effects of different steroids used in intratympanic injections.

OBJECTIVES: This study aimed to compare the side effects of different steroids used in the intratympanic injections (IT). METHODS: One hundred and sixty patients diagnosed with sudden sensorineural hearing loss and undergoing IT were assigned to four groups based on the type or concentration of steroids administered (Group DM5: 5 mg/ml Dexamethasone sodium phosphate; Group DM10: 10 mg/ml Dexamethasone sodium phosphate; Group MP: 40 mg/ml Methylprednisolone sodium succinate; Group BM: 4 mg/ml Betamethasone sodium phosphate). Each group comprised 40 patients, and all participants received IT six times. The study assessed and compared the degrees and duration of pain, dizziness, and tympanic membrane damage following IT. Patients were asked to report the pain they felt using the numeric rating scale (NRS). RESULTS: NRS scores for pain after IT showed significant differences among the four groups (p < 0.001). The average NRS scores for pain in each group were as follows: Group DM5: 1.53 ± 1.04; Group DM10: 1.45 ± 1.30; Group MP: 4.33 ± 2.22; Group BM: 6.03 ± 1.46. The durations of pain after IT also exhibited significant differences among the four groups (p < 0.001), with the longest duration observed in Group MP at 31.93 ± 15.20 min. CONCLUSION: Different types of steroids could lead to varying degrees of pain when used in IT. Betamethasone could cause the most severe pain, and methylprednisolone could result in the longest duration of pain.

Methylprednisolone as Adjunct to Endovascular Thrombectomy for Large-Vessel Occlusion Stroke: The MARVEL Randomized Clinical Trial.

Importance: It is uncertain whether intravenous methylprednisolone improves outcomes for patients with acute ischemic stroke due to large-vessel occlusion (LVO) undergoing endovascular thrombectomy. Objective: To assess the efficacy and adverse events of adjunctive intravenous low-dose methylprednisolone to endovascular thrombectomy for acute ischemic stroke secondary to LVO. Design, Setting, and Participants: This investigator-initiated, randomized, double-blind, placebo-controlled trial was implemented at 82 hospitals in China, enrolling 1680 patients with stroke and proximal intracranial LVO presenting within 24 hours of time last known to be well. Recruitment took place between February 9, 2022, and June 30, 2023, with a final follow-up on September 30, 2023. Interventions: Eligible patients were randomly assigned to intravenous methylprednisolone (n = 839) at 2 mg/kg/d or placebo (n = 841) for 3 days adjunctive to endovascular thrombectomy. Main Outcomes and Measures: The primary efficacy outcome was disability level at 90 days as measured by the overall distribution of the modified Rankin Scale scores (range, 0 [no symptoms] to 6 [death]). The primary safety outcomes included mortality at 90 days and the incidence of symptomatic intracranial hemorrhage within 48 hours. Results: Among 1680 patients randomized (median age, 69 years; 727 female [43.3%]), 1673 (99.6%) completed the trial. The median 90-day modified Rankin Scale score was 3 (IQR, 1-5) in the methylprednisolone group vs 3 (IQR, 1-6) in the placebo group (adjusted generalized odds ratio for a lower level of disability, 1.10 [95% CI, 0.96-1.25]; P = .17). In the methylprednisolone group, there was a lower mortality rate (23.2% vs 28.5%; adjusted risk ratio, 0.84 [95% CI, 0.71-0.98]; P = .03) and a lower rate of symptomatic intracranial hemorrhage (8.6% vs 11.7%; adjusted risk ratio, 0.74 [95% CI, 0.55-0.99]; P = .04) compared with placebo. Conclusions and Relevance: Among patients with acute ischemic stroke due to LVO undergoing endovascular thrombectomy, adjunctive methylprednisolone added to endovascular thrombectomy did not significantly improve the degree of overall disability.

Effect of corticosteroid dosing on outcomes in high-grade immune checkpoint inhibitor hepatitis.

BACKGROUND AND AIMS: Consensus guidelines recommend high-dose corticosteroids (1-2 mg/kg/day methylprednisolone equivalents) for treating grade ≥3 immune checkpoint inhibitor (ICI) hepatitis. We examined the effect of corticosteroid dosing on time to alanine aminotransferase (ALT) normalization, need for additional immunosuppression, and steroid-related complications. APPROACH AND RESULTS: We conducted a retrospective cohort study of 215 ICI-treated patients from 2010 to 2020 who developed grade ≥3 (ALT > 200 U/L) ICI hepatitis. Patients were grouped by initial corticosteroid dose (≥1.5 mg/kg or <1.5 mg/kg methylprednisolone equivalents). Propensity scores were calculated predicting the risk of receiving the higher steroid dose and used in inverse probability of treatment weighted (IPTW) logistic or Cox regression. The 87 patients in the ≥1.5 mg/kg group received higher initial (2.0 vs. 0.8 mg/kg/day, p < 0.001) and maximum (2.0 vs. 1.0 mg/kg/day, p < 0.001) steroid doses than the 128 patients in the <1.5 mg/kg group. There was no difference between the higher versus lower-dose groups in development of steroid-refractory hepatitis (OR 1.22, 95% CI 0.79-1.89, p = 0.365) on IPTW-logistic regression. In patients with steroid-responsive disease, there was no difference between the two groups in time to ALT normalization using either standard Cox regression (HR 1.02, 95% CI 0.72-1.45, p = 0.903) or IPTW-Cox regression (HR 1.09, 95% CI 0.78-1.51, p = 0.610). The ≥1.5 mg/kg group had longer exposure to corticosteroids (median 60 vs. 44 days, p = 0.005) and higher incidences of infection (18.4% vs. 7.0%, relative risk [RR] 2.6, 95% CI 1.2-5.6, p = 0.011) and hyperglycemia requiring treatment (23.3% vs. 7.8%, RR 3.0, 95% CI 1.5-6.0, p = 0.001). CONCLUSIONS: In patients with high-grade ICI hepatitis, initial treatment with 1 mg/kg/day methylprednisolone equivalents provides similar hepatitis outcomes with reduced risk of steroid-related complications when compared with higher-dose regimens.

Protective effects of methylprednisolone-cyclophosphamide treatment on bleomycin-induced pulmonary fibrosis.

BACKGROUND: Methylprednisolone (MP) and cyclophosphamide (CTX) combination treatment has shown great benefits in improving pulmonary fibrosis (PF) and high safety. Currently, the mechanism underlying the effects of MP-CTX on improving PF remains unclear. This study determined the effects of MP-CTX combination treatment on the modulation of inflammation, oxidative stress, and T-cell immunity in PF. METHODS: PF rat models were induced by bleomycin stimulation. MP (3 mg/kg) and MP-CTX (MP: 3 mg/kg; CTX: 8 mg/kg) combination were administered in the PF + MP and PF + MP + CTX groups, respectively. Transmission electron microscopy, hematoxylin and eosin staining, Ashcroft score, and Masson trichrome staining were performed to measure lung morphology in PF. Enzyme-linked immunosorbent assay and quantitative polymerase chain reaction assay were performed to quantify inflammatory factors. Malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-PX) levels were determined using commercial kits. α-Smooth muscle actin (SMA) and collagen I levels were determined using western blotting and immunohistochemistry. The T-cell count was evaluated using flow cytometry. RESULTS: MP-CTX reduced lung injury, collagen deposition, and α-SMA and collagen I levels in a bleomycin-induced PF rat model. Additionally, MP-CTX decreased the levels of MDA and inflammatory factors (tumor necrosis factor-α, interleukin-1ß, and interleukin-6) but increased the activities of SOD and GSH-PX. Furthermore, MP-CTX changed T-cell types in lung tissues, such as increasing CD4+CD25+Foxp3+ cell count. CONCLUSIONS: MP-CTX combination treatment improved the degree of PF by reducing inflammation and oxidative stress and improving T-cell immunity. These findings provide novel insights into the mechanisms underlying the effects of MP-CTX on PF.

Effectiveness and safety profile of greater occipital nerve blockade in cluster headache: a systematic review.

BACKGROUND: Greater occipital nerve (GON) blockade is a short-term preventive therapy for cluster headache (CH). We conducted a systematic review to evaluate the effectiveness and safety of GON blockade in patients with CH. METHODS: On 23 October 2020, we searched MEDLINE, Embase, Embase Classic, PsycINFO, CINAHL, CENTRAL and Web of Science databases from their inception date. Studies included participants with a CH diagnosis who received corticosteroid and local anaesthetic suboccipital region injections. Outcomes were change in the frequency/severity/duration of attacks; proportion of participants responding to treatment, time to attack freedom from an attack, change in attack bout length and/or the presence of adverse effects after GON blockade. Risk of bias was assessed with the Cochrane Risk of Bias V.2.0 (RoB2)/Risk of Bias in Non-randomized Studies - of Interventions (ROBINS- I) tools and a specific tool for case reports/series. RESULTS: Two RCTs, eight prospective and eight retrospective studies, and four case reports were included in the narrative synthesis. Every effectiveness study found a significant response in one or more of frequency/severity/duration of individual attacks or proportion of patients responding to treatment (47.8%-100.0%). There were five instances of potentially irreversible adverse effects. A higher injectate volume and use of concurrent prophylaxis may be associated with an increased likelihood of response. Methylprednisolone may have the best safety profile of available corticosteroids. DISCUSSION: GON blockade is safe and effective for CH prevention. Higher injectate volumes may improve likelihood of response, and the likelihood of serious adverse events may be reduced by using methylprednisolone. PROSPERO REGISTRATION NUMBER: CRD42020208435.

Efficacy and safety of methylprednisolone pulse followed by oral prednisone vs. oral prednisone alone in sarcoidosis tubulointerstitial nephritis: a randomized, open-label, controlled clinical trial.

BACKGROUND: We determine the benefit of pulsed methylprednisolone for improving kidney function in patients with sarcoidosis tubulointerstitial nephritis. METHODS: We conducted a multicenter, prospective, randomized, open-label, controlled trial in patients with biopsy-proven acute tubulointerstitial nephritis caused by sarcoidosis at 21 sites in France. Patients were randomly assigned to receive a methylprednisolone pulse 15 mg/kg/day for 3 days, then oral prednisone (MP group) or oral prednisone 1 mg/kg/day alone (PRD group). The primary end point was a positive response at 3 months, defined as a doubling of estimated glomerular filtration rate (eGFR) compared with the eGFR before randomization. RESULTS: We randomized 40 participants. Baseline eGFR before PRD was 22 mL/min/1.73m2 {interquartile range [IQR], 16-44} and before MP was 25 mL/min/1.73m2 (IQR, 22-36) (P = .3). The two groups did not differ in underlying pathological lesions, including mean percentage of interstitial fibrosis and intensity of interstitial infiltrate. In the intent-to-treat population, the median eGFR at 3 months did not significantly differ between the PRD and MP groups: 45 (IQR, 34-74) and 46 (IQR, 39-65) mL/min/1.73m2. The primary end point at 3 months was achieved in 16 of 20 (80%) PRD patients and 10 of 20 (50%) MP patients (P = .0467). The eGFR was similar between the two groups after 1, 3, 6, and 12 months of treatment. For both groups, eGFR at 1 month was strongly correlated with eGFR at 12 months (P < .0001). The two groups did not differ in severe adverse events. CONCLUSION: Compared with a standard oral steroid regimen, intravenous MP may have no supplemental benefit for renal function in patients with tubulointerstitial nephritis caused by sarcoidosis.Trial Registration: ClinicalTrials.gov: NCT01652417; EudraCT: 2012-000149-11.

ANCA-associated pulmonary-renal syndrome treated with cyclophosphamide, rituximab, repeated methyl-prednisolone pulses and a reduced oral glucocorticoid regime: an observational study.

OBJECTIVES: To describe the clinical outcome of patients with pulmonary-renal syndrome (PRS) due to ANCA-associated vasculitis (AAV) from a single centre. METHODS: Observational study of routine clinical care data of patients diagnosed with PRS due to AAV from 2010 to 2020 at the Autoimmune Diseases Unit, Hospital Universitario Cruces. Mortality due to any cause within 24 months was defined as the primary outcome. Secondary outcomes included end-stage kidney disease and the need for oxygen therapy at 24 months. RESULTS: Fourteen patients were identified with a mean age at diagnosis of 62.71 years. At diagnosis, the median serum creatinine was 2.46 mg/dl and the median Birmingham Vasculitis Activity Score (BVAS) was 24. All patients were treated with repeated methyl-prednisolone pulses, 13 patients received iv cyclophosphamide 500 mg every two weeks and 12 patients received rituximab. The mean (SD) initial dose of oral prednisone was 25 (7) mg/d. A rapid tapering of oral prednisone was achieved in all patients as per protocol, with a mean (SD) dose of 10.6 (1.9) mg/d received within the first three months. No cases of death, end-stage kidney disease or with need for long-term oxygen therapy were seen. Three patients suffered a relapse and five patients had major infections, none of them opportunistic. The median creatinine and BVAS at 24 months were 1.30 mg/dl and 0, respectively. CONCLUSIONS: Combination therapy with iv cyclophosphamide and rituximab, with repeated methyl-prednisolone pulses and a rapid prednisone taper, results in early disease control, with low mortality, chronic organ damage and infections.

Efficacy and safety of glucocorticoids use in patients with COVID-19: a systematic review and network meta­analysis.

BACKGROUND: Currently, some meta-analyses on COVID-19 have suggested that glucocorticoids use can reduce the mortality rate of COVID-19 patients, utilization rate of invasive ventilation, and improve the prognosis of patients. However, optimal regimen and dosages of glucocorticoid remain unclear. Therefore, the purpose of this network meta-analysis is to analyze the efficacy and safety of glucocorticoids in treating COVID-19 at regimens. METHODS: This meta-analysis retrieved randomized controlled trials from the earliest records to December 30, 2022, published in PubMed, Embase, Cochrane Library, CNKI Database and Wanfang Database, which compared glucocorticoids with placebos for their efficacy and safety in the treatment of COVID-19, Effects of different treatment regimens, types and dosages (high-dose methylprednisolone, very high-dose methylprednisolone, Pulse therapy methylprednisolone, medium-dose hydrocortisone, high-dose hydrocortisone, high-dose dexamethasone, very high-dose dexamethasone and placebo) on 28-day all-caused hospitalization mortality, hospitalization duration, mechanical ventilation requirement, ICU admission and safety outcome were compared. RESULTS: In this network meta-analysis, a total of 10,544 patients from 19 randomized controlled trials were finally included, involving a total of 9 glucocorticoid treatment regimens of different types and dosages. According to the analysis results, the 28-day all-cause mortality rate was the lowest in the treatment with pulse therapy methylprednisolone (OR 0.08, 95% CI 0.02, 0.42), but the use of high-dose methylprednisolone (OR 0.85, 95% CI 0.59, 1.22), very high-dose dexamethasone (OR 0.95, 95% CI 0.67, 1.35), high-dose hydrocortisone (OR 0.64, 95% CI 0.34, 1.22), medium-dose hydrocortisone (OR 0.80, 95% CI 0.49, 1.31) showed no benefit in prolonging the 28-day survival of patient. Compared with placebo, the treatment with very high-dose methylprednisolone (MD = -3.09;95%CI: -4.10, -2.08) had the shortest length of hospital stay, while high-dose dexamethasone (MD = -1.55;95%CI: -3.13,0.03) and very high-dose dexamethasone (MD = -1.06;95%CI: -2.78,0.67) did not benefit patients in terms of length of stay. CONCLUSIONS: Considering the available evidence, this network meta­analysis suggests that the prognostic impact of glucocorticoids in patients with COVID-19 may depend on the regimens of glucocorticoids. It is suggested that pulse therapy methylprednisolone is associated with lower 28-day all-cause mortality, very high-dose methylprednisolone had the shortest length of hospital stay in patients with COVID-19.

Corticosteroids in the treatment of IgA nephropathy: lessons from the TESTING trial.

IgA nephropathy (IgAN), the most common form of primary glomerulonephritis, is mainly observed in young adults and children. Clinical and basic studies indicate the role of immunity in IgAN pathogenesis; however, corticosteroid therapy has been controversial in past decades. The TESTING study, initiated in 2012, is an international, multicenter, double-blinded, randomized, placebo-controlled trial that aimed to evaluate oral methylprednisolone's safety and long-term efficacy under conditions of optimized supportive treatment in patients with IgAN whose risk of progression is high. After a decade of effort, the successful completion of the TESTING study showed that a 6- to 9-month course of oral methylprednisolone is an effective regimen to protect kidney function in high-risk patients with IgAN, but also demonstrated safety concerns. Compared with the full-dose regimen, the reduced-dose regimen was reported to be beneficial, with successfully increased safety. Overall, the TESTING trial provided more data regarding the treatment dosage and safety of corticosteroids, a cost-effective therapy, in IgAN, which have important implications for pediatric patients with IgAN. With a deeper understanding of the disease pathogenesis of IgAN, ongoing studies of novel therapeutic regimens would help further optimize the benefit-risk ratio.

Corticosteroid-Associated Avascular Necrosis of the Femoral Head in Patients with Severe COVID-19: A Single-Center Study.

BACKGROUND Avascular necrosis (AVN) of the femoral head can result from high-dose corticosteroid therapy. Given that severe COVID-19 pneumonia patients respond positively to corticosteroids, this study aimed to explore the incidence of femoral head AVN associated with corticosteroid therapy in 24 patients diagnosed with severe COVID-19 at a single center. MATERIAL AND METHODS The study included 24 patients who were diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection through real-time reverse transcription polymerase chain reaction test (rRT-PCR) and with COVID-19 pneumonia via high-resolution computed tomography (HRCT). Moderate cases received 2×4 mg Dexamethasone while severe cases were also administered with 3×40 mg Methylprednisolone. Diagnosis of femoral head AVN was confirmed with magnetic resonance imaging (MRI) and radiographs, which was subsequently treated by a total hip arthroplasty (THA) or a core decompression surgery (CDS) in line with the Ficat and Arlet classifications RESULTS Among the patients, 8 had a moderate infection course, while 16 were severe. The mean corticosteroid duration was 15±5 days for Dexamethasone and 30 days for Methylprednisolone. Severe patients presented with higher grade femoral head AVN and greater pain levels compared to moderate cases (p<0.05). Four patients developed bilateral AVN. The treatment resulted in 23 THAs and 5 CDSs CONCLUSIONS The data from this study corroborate earlier studies and case reports, suggesting an increased occurrence of AVN of the femoral head during the COVID-19 pandemic due to the high-dose corticosteroid therapy employed for patients hospitalized with severe COVID-19 pneumonia.

Oral or pulse glucocorticoid use at the onset of giant cell arteritis and its influence on the risk of relapse: a retrospective study.

The objective is to investigate whether initial therapy with intravenous methylprednisolone pulses (ivMTP) or oral glucocorticoid (OG) influences the relapse rate in giant cell arteritis (GCA) patients. This is a retrospective observational study of patients with GCA from 2004 to 2021. Demographics, clinical and laboratory variables, cumulative glucocorticoid dose and relapse rate at 6-month follow-up defined according to EULAR recommendations were recorded. Univariate and multivariate logistic regression models were used to determine possible risk factors for relapse. A total of 74 GCA patients were included for analysis (54 (73%) female, mean (SD) age 77.2 (7.4) years). Overall, 47 (63.5%) patients received ivMTP at disease onset and 27 (36.5%) OG. Mean (SD) cumulative prednisone dose (mg) at 6-month follow-up was 3790.7 (1832.7) for patients with ivMTP vs 4298.1 (2930.6) for the OG group, p = 0.37. A total of 15 (20.3%) relapses occurred at 6-month follow-up. Relapse rates did not differ according to the initial therapy (19.1 vs 22.2%, respectively, p = 0.75). In the multivariate analysis, fever at disease onset (OR 4.837; CI 1.1-21.6) and dyslipidemia (OR 5.651; CI 1.1-28.4) were independent predictors for relapse. Initial therapy with ivMTP or OG does not influence the relapse rate of GCA patients. Fever at disease onset and dyslipidemia are independent predictors of disease relapse.

Comparison of triamcinolone and methylprednisolone efficacy and steroid flare reaction rates after shoulder corticosteroid injection: a prospective interrupted time series study.

BACKGROUND: A corticosteroid flare reaction is a well-described phenomenon that causes significant pain and dysfunction. The paucity of literature impedes decision making regarding which corticosteroid to use for shoulder injection. The purpose of this study was to compare methylprednisolone acetate (MPA) and triamcinolone acetonide (TA) injections in the glenohumeral joint and/or subacromial space in terms of efficacy and the incidence of steroid flare reactions. METHODS: In this prospective, interrupted time series, parallel study, patients received injections in the glenohumeral joint and/or subacromial space. MPA and TA were used during 2 discrete 3-month periods. The injections consisted of 2 mL of lidocaine, 2 mL of bupivacaine, and 80 mg of either MPA or TA. Visual analog scale (VAS) pain scores were recorded immediately before injection; 1-7 days after injection; and 3, 6, and 12 months after injection. The primary outcome was the incidence of a steroid flare reaction, defined as a post-injection increase in the VAS score by ≥2 points. The secondary outcome was injection failure, defined as a post-injection VAS score greater than the baseline score or the need for another intervention. We used linear mixed models with a patient-level random intercept to identify the mean VAS score change for TA injections in the first week after injection. RESULTS: MPA or TA shoulder injections were administered in 421 patients; of these patients, 15 received bilateral-joint injections whereas 406 received a single-joint injection, for a total of 436 injections (209 MPA and 227 TA injections). Pain scores in the first week after injection were available for 193 MPA and 199 TA injections. Significantly more patients in the MPA cohort reported flare reactions compared with the TA cohort (22.8% vs. 4.0%, P < .001) during the first week after injection. In the first week after injection, the mean VAS score of patients receiving TA injections was 1.05 (95% confidence interval, 0.47-1.63) lower than that of patients receiving MPA injections when adjusted for age, sex, race, pain type, surgeon type, and injection site. At 3 months, surveys for 169 MPA and 172 TA injections were completed, with no significant difference in the rate of injection failure for MPA vs. TA (42.6% vs. 36.1%, P = .224). Treatment failure rates were significantly higher for MPA than for TA at 6 months (78.44% vs. 62.5%, P < .001) but not at 12 months (81.18% vs. 81.42%, P = .531.) CONCLUSION: TA injections resulted in a >5-fold reduction in steroid flare reactions, with statistically superior 6-month efficacy rates, compared with MPA injections. This study supports TA as a more viable corticosteroid option for shoulder injection.

The anti-inflammatory effects of minocycline on lipopolysaccharide-induced paw oedema in rats: a histopathological and molecular study.

Minocycline is a semi-synthetic antimicrobial agent with claimed anti-inflammatory properties reported from different experimental models. This study was aimed to evaluate the anti-inflammatory effects of minocycline, compared to the actions of two common anti-inflammatory agents, on lipopolysaccharide (LPS)-induced paw oedema through some clinical, histopathological, haematological and molecular analyses. Forty-eight rats were divided into eight groups (n = 6). In control group (Ctrl), each animal was injected with normal saline into its sub-plantar region of hind paw. In groups 2-7, hind paw oedema was induced by injection of LPS. One hour before injections, groups 1 (Ctrl) and 2 (LPS) were treated orally with distilled water, 3 and 4 with methylprednisolone (Pred) and meloxicam (Melo) and 5-7 with minocycline in doses of 50, 150 and 450 mg/kg (M50, M150 and M450, respectively). The 8th group (MC) was given minocycline (150 mg/kg) orally and normal saline was injected into sub-plantar region. Paw swelling and body temperature were assessed at 0, 2, 4, 6 and 24 h post-injections. At 24 h, samples of blood and liver, kidney, spleen and hind paw tissues were taken for haematological and histopathological examinations. Some samples of the paw were also obtained for molecular analysis of some inflammatory-related cytokines at mRNA level. Paw swelling and body temperature increased in all LPS-injected groups 2 h post-injection. In LPS group, they remained significantly increased up to 24 h; however, these parameters decreased to normal in Pred, Melo and all minocycline groups. The histological findings showed mild-to-moderate signs of inflammation in tissue samples of groups 2-6, but not in group M450. Additionally, gene expression of pro-inflammatory cytokines (IL-1ß and IL-6) increased significantly in LPS group compared to other groups. In conclusion, this study supports the role of minocycline as an anti-inflammatory agent with effects comparable to those of meloxicam and methylprednisolone.

Comparison of the efficacy of equivalent doses of dexamethasone, methylprednisolone, and hydrocortisone for treatment of COVID-19-related acute respiratory distress syndrome: a prospective three-arm randomized clinical trial.

BACKGROUND: This prospective controlled clinical trial aimed to compare the efficacy of methylprednisolone, dexamethasone, and hydrocortisone at equivalent doses in patients with severe COVID-19. METHODS: In total, 106 patients with mild to moderate COVID-19-related acute respiratory distress syndrome (ARDS) were randomized to receive either dexamethasone (6 mg once a day), methylprednisolone (16 mg twice a day), or hydrocortisone (50 mg thrice a day) for up to 10 days. All participants received a standard of care for COVID-19. The primary and secondary efficacy outcomes included all-cause 28-day mortality, clinical status on day 28 assessed using the World Health Organization (WHO) eight-category ordinal clinical scale, number of patients requiring mechanical ventilation and intensive care unit (ICU) care, number of ventilator-free days, length of hospital and ICU stay, change in PaO2:FiO2 ratios during the first 5 days after treatment, and incidence of serious adverse events. P-values below 0.008 based on Bonferroni's multiple-testing correction method were considered statistically significant. RESULTS: According to the obtained results, there was a trend toward more favorable clinical outcomes in terms of needing mechanical ventilation and ICU care, number of ventilator-free days, change in PaO2:FiO2 ratios during the first 5 days after treatment, clinical status score at day 28, length of ICU and hospital stay, and overall 28-day mortality in patients receiving dexamethasone compared to those receiving methylprednisolone or hydrocortisone; however, likely due to the study's small sample size, the difference between groups reached a significant level only in the case of clinical status score on day 28 (p-value = 0.003). There was no significant difference in the incidence of serious adverse events between the study groups. CONCLUSION: Based on the results, severe cases of COVID-19 treated with dexamethasone might have a better clinical status at 28-day follow-up compared to methylprednisolone and hydrocortisone at an equivalent dose. Larger multicenter trials are required to confirm our findings.

A rare case of drug-induced bradycardia associated with the just low dose use of methylprednisolone in a child with COVID-19.

Methylprednisolone (MP) is usually used to reduce inflammation reaction and tissue damage, which may have a beneficial treatment effect on coronavirus disease 2019 (COVID-19). However, we present the case of a child who manifests significant bradycardia with the use of just low dose MP on the premise of the long-term use of arbidol. Arbidol can affect the activity of CYP3A4, which is also a key metabolic enzyme of MP by competitive inhibition, and which is easy to aggravate the side effects of MP. Therefore, more attention should be paid to bradycardia occurrence in the patient with COVID-19 when MP is considered in COVID-19.

Comparison of pulse-dose and high-dose corticosteroids with no corticosteroid treatment for COVID-19 pneumonia in the intensive care unit.

Corticosteroid dosing in the range of 0.5-2 mg/kg/day of methylprednisolone equivalents has become a standard part of the management of intensive care unit (ICU) patients with COVID-19 pneumonia based on positive results of randomized trials and a meta-analysis. Alongside such conventional dosing, administration of 1 gm of methylprednisolone daily (pulse dosing) has also been reported in the literature with claims of favorable outcomes. Comparisons between such disparate approaches to corticosteroids for Coronavirus disease 2019 (COVID-19) pneumonia are lacking. In this retrospective study of patients admitted to the ICU with COVID-19 pneumonia, we compared patients treated with 0.5-2 mg/kg/day in methylprednisolone equivalents (high-dose corticosteroids) and patients treated with 1 gm of methylprednisolone (pulse-dose corticosteroids) to those who did not receive any corticosteroids. The endpoints of interest were hospital mortality, ICU-free days at Day 28, and complications potentially attributable to corticosteroids. Pulse-dose corticosteroid therapy was associated with a significant increase in ICU-free days at Day 28 compared to no receipt: adjusted relative risk (aRR): 1.45 (95% confidence interval [CI]: 1.05-2.02; p = 0.03) and compared with high-dose corticosteroid administration (p = 0.003). Nonetheless, receipt of high-dose corticosteroids-but not of pulse-dose corticosteroids-significantly reduced the odds of hospital mortality compared to no receipt: adjusted Odds ratio (aOR) 0.31 (95% CI: 0.12-0.77; p = 0.01). High-dose corticosteroids reduced mortality compared to pulse-dose corticosteroids (p = 0.04). Pulse-dose corticosteroids-but not high-dose corticosteroids-significantly increased the odds of acute kidney injury requiring renal replacement therapy compared to no receipt: aOR 3.53 (95% CI: 1.27-9.82; p = 0.02). The odds of this complication were also significantly higher in the pulse-dose group when compared to the high-dose group (p = 0.05 for the comparison). In this single-center study, pulse-dose corticosteroid therapy for COVID-19 pneumonia in the ICU was associated with an increase in ICU-free days but failed to impact hospital mortality, perhaps because of its association with development of severe renal failure. In line with existing trial data, the effect of high-dose corticosteroids on mortality was favorable.
