OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

OBJECTIVE: Glucocorticoid-induced osteoporosis (GIOP) is a common complication of prolonged glucocorticoid therapy. Chlorogenic acid (CGA), a polyphenol with antioxidant properties that is extracted from traditional Chinese medicines such as Eucommiae Cortex, has potential anti-osteoporotic activity. This study aimed to investigate the possible effects of CGA on GIOP in mice and murine long bone osteocyte Y4 (MLO-Y4) cells and explore the underlying molecular mechanisms. METHODS: The protective effects of CGA were initially evaluated in the GIOP mouse model induced by dexamethasone (Dex). The micro-computed tomography, hematoxylin-eosin staining, silver nitrate staining, and serum detection were used to assess the efficacy of CGA for improving bone formation in vivo. Then, network pharmacology analysis was used to predict the potential targets and molecular mechanisms underlying the therapeutic efficacy of CGA against GIOP. After that, 2',7'-dichlorofluorescein diacetate staining, flow cytometry, real-time quantitative reverse transcription polymerase chain reaction, and Western blotting were used to verify the mechanisms of CGA against GIOP in vitro. RESULTS: Animal experiments showed that CGA treatment effectively attenuated Dex-induced decreases in bone mass and strength and improved disrupted osteocyte morphology in mice. The protein-protein interaction analysis highlighted erb-b2 receptor tyrosine kinase (ERBB2), which is also known as human epidermal growth factor receptor 2 (HER2), caspase-3, kinase insert domain receptor, matrix metallopeptidase 9, matrix metallopeptidase 2, proto-oncogene tyrosine-protein kinase Src, and epidermal growth factor receptor as core targets. The Kyoto Encyclopedia of Genes and Genomes analysis revealed several significantly enriched pathways (P < 0.05), including the ERBB, phosphoinositide 3 kinase-AKT serine/threonine kinase 1 (AKT), and mechanistic target of rapamycin kinase (mTOR) pathways. Cellular experiments verified that CGA enhanced bone formation and promoted autophagy while inhibiting apoptosis in MLO-Y4 cells exposed to Dex, which was associated with the upregulated expression of HER2 and activation of the HER2/AKT/mTOR signaling pathway. CONCLUSION CGA exerted anti-osteoporotic effects against GIOP, partially through targeting osteocytes and modulating the HER2/AKT/mTOR signaling pathway.

OBJECTIVES: To investigate the clinical characteristics of cytokine release syndrome (CRS) in children with thalassemia major (TM) after haploidentical hematopoietic stem cell transplantation (haplo-HSCT) and their prognosis. METHODS: A retrospective analysis was performed for the clinical data of 280 children with TM who underwent haplo-HSCT in the Department of Hematology and Oncology, Shenzhen Children's Hospital, from January 2019 to December 2021. According to the CRS criteria, they were divided into two groups: CRS grade <3 (260 children) and CRS grade ≥3 (20 children). The children with TM were analyzed in terms of clinical characteristics of CRS after haplo-HSCT and their prognosis. RESULTS: There were significant differences between the two groups in neutrophil engraftment time, clinical manifestations of CRS, and the rate of use of glucocorticoids within 4 days after haplo-HSCT (P=0.012, 0.040, and <0.001 respectively). For the CRS grade <3 group, the incidence rate of acute graft-versus-host disease (aGVHD) was 9.6% within 3 months after transplantation, while no aGVHD was observed in the CRS grade ≥3 group within 3 months after transplantation, but there was no significant difference in the incidence of aGVHD between the two groups within 3 months after transplantation (P=0.146). No transplantation-related death was observed in either group within 3 months after haplo-HSCT. CONCLUSIONS The children with CRS grade≥3 have an early neutrophil engraftment time, severe and diverse clinical manifestations of CRS, and a high rate of use of glucocorticoids within 4 days after haplo-HSCT. For these children, early use of low-dose glucocorticoids after transplantation may alleviate CRS response and reduce the incidence of aGVHD, thereby bringing more benefits to the children. CRS after haplo-HSCT has no significant impact on the prognosis of the children.

Rheumatoid arthritis (RA) and myasthenia gravis (MG) are two distinct autoimmune diseases. Compared with the general population, the incidence of RA is notably higher among patients with MG. Similarly, the rate of MG in patients diagnosed with RA is also significantly increased. In this report, we presented an elderly female patient with a history usage of long-term glucocorticoid and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), whose RA symptoms remained inadequately controlled. She later exhibited drooping of the right eyelid and double vision, leading to a diagnosis of ocular myasthenia gravis (OMG). Then, we made a literature review and found that the RA patients with co-existing MG were relatively more common in middle-aged and elderly women, and most of them did not have thymoma. Thymoma wasn ' t found in our patient, which was consistent with the cli-nical characteristics of RA complicated with MG reported in previous reports. In addition, there was li-mited treatment experience in patients with both RA and MG. The treatment stratergies for RA or MG included glucocorticoids and immunosuppressants. Among the 18 patients we analyzed, 8 patients expe-rienced relief after csDMARDs, while other 8 patients received biologics or targeted DMARDs, including tumor necrosis factor inhibitors (TNFi) in 5 cases, JAK inhibitors in 2 cases, and B-cell depletion therapy (rituximab) in 2 cases. What called for special attention was that one RA patient was diagnosed with MG after using 23 months of methotrexate and 6 weeks of etanercept (TNFi), with rituximab 1 000 mg for the first time, followed by 500 mg every 6 months, and finally both RA and MG were well controlled. For the patient in this study, MG symptoms improved with increased dosage of prednisone. In order to tapper the dose of glucocorticoid, it was necessary for more potent immunosuppressant for both RA and MG. Given her history of cardiac conditions, JAK inhibitors were not considered, and due to the uncertain efficacy of TNFi, we chose to administer low-dose rituximab (100 mg). Subsequent follow-up revealed stable conditions for both RA and MG, allowing for discontinuance of glucocorticoid after 5 months. It reflected the potential efficacy and cost-effectiveness of low-dose, long-interval rituximab in treating RA patients combined with MG, while it also minimized infection risks. However, the duration for subsequent infusions remained uncertain and required further observation. In conclusion, RA combined with MG is rare. For patients exhibiting poor responses to csDMARDs, low-dose, long-interval rituximab might be a promising treatment option.

OBJECTIVES: To investigate the change in the distribution of memory B cell subsets in children with frequently relapsing nephrotic syndrome (FRNS) during the course of the disease. METHODS: A total of 35 children with primary nephrotic syndrome (PNS) who attended the Department of Pediatrics of the Affiliated Hospital of Xuzhou Medical University from October 2020 to October 2021 were enrolled as subjects in this prospective study. According to the response to glucocorticoid (GC) therapy and frequency of recurrence, the children were divided into two groups: FRNS (n=20) and non-FRNS (NFRNS; n=15). Fifteen children who underwent physical examination were enrolled as the control group. The change in memory B cells after GC therapy was compared between groups, and its correlation with clinical indicators was analyzed. RESULTS: Before treatment, the FRNS and NFRNS groups had significantly increased percentages of total B cells, total memory B cells, IgD⁺ memory B cells, and IgE⁺ memory B cells compared with the control group, and the FRNS group had significantly greater increases than the NFRNS group (P<0.05); the FRNS group had a significantly lower percentage of class-switched memory B cells than the NFRNS and control groups (P<0.05). After treatment, the FRNS and NFRNS groups had significant reductions in the percentages of total B cells, total memory B cells, IgM⁺IgD⁺ memory B cells, IgM⁺ memory B cells, IgE⁺ memory B cells, IgD⁺ memory B cells, and IgG⁺ memory B cells (P<0.05) and a significant increase in the percentage of class-switched memory B cells (P<0.05). The FRNS group had a significantly higher urinary protein quantification than the NFRNS and control groups (P<0.05) and a significantly lower level of albumin than the control group (P<0.05). In the FRNS group, urinary protein quantification was negatively correlated with the percentage of class-switched memory B cells and was positively correlated with the percentage of IgE⁺ memory B cells (P<0.05). CONCLUSIONS Abnormal distribution of memory B cell subsets may be observed in children with FRNS, and the percentages of IgE⁺ memory B cells and class-switched memory B cells can be used as positive and negative correlation factors for predicting recurrence after GC therapy in these children.

Objective: To elucidate the clinical features of patients with refractory juvenile dermatomyositis (JDM), and to explore the efficacy and safety of tofacitinib in the treatment of refractory JDM. Methods: A total of 75 JDM patients admitted to the Department of Rheumatology and Immunology in Shenzhen Children's Hospital from January 2012 to January 2021 were retrospectively analyzed, and to analyze the clinical manifestations, efficacy and safety of tofacitinib in the treatment of refractory JDM. Patients were divided into refractory group with using of glucocorticoids in combination with two or more anti-rheumatic drugs for treatment, and the presence of disease activity or steroid dependence after a one-year follow-up. The non-refractory group is defined as clinical symptoms disappeared, laboratory indicators were normal, and clinical remission was achieved after initial treatment, and the clinical manifestations and laboratory indexes of the two groups were compared. The Mann-Whitney U test, Fisher's precision probability test was used for intergroup comparison. Binary Logistic multivariate regression analysis was used to identify risk factors for refractory JDM. Results: Among the 75 children with JDM, 41 were males and 34 were females with a age of onset of 5.3 (2.3, 7.8) years. The refractory group consisted of 27 cases with a age of onset of 4.4 (1.5, 6.8) years, while the non-refractory group consisted of 48 cases with a age of onset of 5.9 (2.5, 8.0) years. Compared with 48 cases in the non-refractory group, the proportion of interstitial lesions and calcinosis in the refractory group was higher than that in the non-refractory group (6 cases (22%) vs. 2 cases (4%), 8 cases (30%) vs. 4 cases (8%), both P<0.05). Binary Logistic regression analysis showed that observation group were more likely to be associated with to interstitial lung disease (OR=6.57, 95%CI 1.22-35.31, P=0.028) and calcinosis (OR=4.63, 95%CI 1.24-17.25, P=0.022). Among the 27 patients in the refractory group, 22 cases were treated with tofacitinib, after treatment with tofacitinib, 15 of 19 cases (86%) children with rashes showed improvement, and 6 cases (27%) with myositis evaluation table score less than 48 score both were improved, 3 of 6 cases (27%) had calcinosis were relieved, and 2 cases (9%) had glucocorticoid-dependence children were successfully weaned off. During the tofacitinib treatment, there was no increase in recurrent infection, blood lipids, liver enzymes, and creatinine were all normal in the 22 cases. Conclusions: Children with JDM with calcinosis and interstitial lung disease are more likely to develop refractory JDM. Tofacitinib is safe and effective for refractory JDM.

Objective: Cancer immunotherapy can lead to various side effects, termed immune-related adverse events (irAE). This study summarized and analyzed the clinical and pathological characteristics of immune-mediated liver injury caused by immune checkpoint inhibitors (ILICI). Methods: This is a retrospective case series study involving 11 patients diagnosed with ILICI at the Peking Union Medical College Hospital from November 2019 to November 2021. Patient demographic information and clinical data, including gender, age, ILICI onset, clinical and radiological manifestations, pathological features, treatment, and resumption of ICI were retrospectively collected and analyzed. Results: The patients were primarily males (9/11) with a median age of 65 (range: 32-73) years. ICI mainly resulted in either partial remission (4/11) or stable disease (3/11). ILICI occurred after a median of two cycles of anti-programmed cell death-1 (PD-1) therapy, with a median time from the initial and last anti-PD-1 therapy to ILICI onset of 57 days and 17 days, respectively. ILICI was mostly severe (3/11) or very severe (6/11). While the clinical and radiological manifestations were non-specific, the pathological features were active lobular hepatitis and portal inflammation, with prominent CD8⁺T lymphocyte infiltration. The basic treatment was hepatoprotective drugs (10/11). Glucocorticoids were used as the primary therapy (9/11) but were ineffective in 4 of 9 cases. Of these, 3 of 9 cases received combined treatment with mycophenolate mofetil (MMF), only one of whom achieved remission. By the end of the study, 2 of 11 cases had resumed ICI and neither had experienced an ILICI relapse. Conclusion: The ILICI patients in this study had a corresponding history of ICI treatment and pathological features. The main treatment included hepatoprotective drugs and glucocorticoids. Immunosuppressive drugs were added for some cases but had poor efficacy.

OBJECTIVES: To investigate the clinical effect of different immunosuppressive treatment regimens in children with ocular myasthenia gravis (OMG). METHODS: A retrospective analysis was conducted on 130 children with OMG who were treated in the Department of Neurology, Jiangxi Children's Hospital, from February 2018 to February 2023. According to the treatment regimen, they were divided into four groups: glucocorticoid (GC) group (n=29), mycophenolate mofetil (MMF) group (GC+MMF; n=33), methotrexate (MTX) group (GC+MTX; n=30), and tacrolimus (FK506) group (GC+FK506; n=38). Treatment outcomes and adverse reactions were compared among the groups. RESULTS: After 3 months of treatment, the FK506 group had significantly lower scores of Myasthenia Gravis Quantitative Scale and Myasthenia Gravis-Specific Activities of Daily Living than the other three groups (P<0.05). After 3 months of treatment, the FK506 group had a significantly lower dose of prednisone than the GC group, and after 6 and 9 months of treatment, the MMF, MTX, and FK506 groups had a significantly lower dose of prednisone than the GC group (P<0.05). After 12 months of treatment, the MMF, MTX, and FK506 groups had a significantly lower incidence rate of GC-related adverse reactions than the GC group (P<0.05). CONCLUSIONS For children with OMG, the addition of various immunosuppressants can reduce the dosage of GC and adverse reactions. Among them, FK506 shows superior efficacy compared to other immunosuppressants in the early treatment of OMG.

Dental erosion is characterized by progressively destroyed teeth, which has no relation to bacteria but to chemicals. Some internal factors, such as gastroesophageal reflux induced by bulimia, anorexia, gastrointestinal diseases, or drugs, and external factors, such as diet, drugs, and occupational acid exposure, are considered promotive factors for this disease. This article presents a patient suffering from severe dental erosion in the whole dentition, especially in the maxillary teeth, due to gastroesophageal reflux induced by glucocorticoid therapy for optic neuritis. This article discusses the mechanism between optic neuritis glucocorticoid therapy and dental erosion.
