Effect of Rituximab Versus Mycophenolate Mofetil or Cyclophosphamide as Control in Lupus Nephritis:A Meta-Analysis

Objective:To evaluate the effects of rituximab versus mycophenolate mofetil or cyclophosphamide as control in lupus nephritis by meta-analysis.Methods:A systematic search was carried out up to January 2022,obtaining 7 studies involving 645 participants with lupus nephritis at the commencement of the investigation;198 of them were treated with rituximab,while 447 were treated with mycophenolate mofetil or cyclophosphamide.We determined the odds ratio(OR)and mean difference(MD)with 95%confidence index(CI)to compare rituximab’s efficacy to that of mycophenolate mofetil or cyclophosphamide as control in lupus nephritis using random-or fixed-effects model by dichotomous or continuous techniques.Results:The rituximab group showed significantly higher complete renal remission rate(OR=2.52;95%CI 1.30-4.91,P=0.006)and total renal remission rates(OR=2.22;95%CI 1.36-3.63,P=0.001)than the control group.However,there was no significant difference in terms of end Systemic Lupus Erythematosus Disease Activity Index(SLEDAI)score(MD-1.16;95%CI-2.88-0.57,P=0.19),proteinuria(MD-0.31;95%CI-0.70-0.09,P=0.013),and serum creatinine(MD 0.01;95%CI-0.04-0.07,P=0.64)between the rituximab group and the control.Conclusion:Rituximab exhibited significantly greater complete renal remission rate and total renal remission rates,with no significant difference in terms of shorter-end SLEDAI,proteinuria,and serum creatinine,compared with the control in individuals with lupus nephritis.

Immunotherapies application in active stage of systemic lupus erythematosus in pregnancy:A case report and review of literature

BACKGROUND Pregnancy in the setting of systemic lupus erythematosus can worsen thecondition from the stable to active stage, with quality of life and fertility desirebeing particular concerns. Pregnancy in the active stage of systemic lupuserythematosus (ASLE), although rare and complicated to manage, can be treatedfavorably with immunotherapies ifs used properly. Here we report such a successcase.CASE SUMMARY A 31-year-old primigravida patient, diagnosed with SLE seven years ago, wasinduced ASLE after a cold at 21 + weeks. The patient’s vital signs on presentationwere normal. Her laboratory exam was remarkable for significant proteinuria,liver and renal dysfunction, and low C3 and C4 levels. Infectious work-up wasnegative. The patient was diagnosed with ASLE. She was given immunosuppressiveagents (methylprednisolone, gamma globulin and azathioprine etc.)and plasma adsorption therapy, monitoring blood pressure every 8 h, fetal heartrate twice a day, and liver and renal function at least twice a week. Successfulmaternal and fetal outcomes are presented here.CONCLUSION Child-bearing in ASLE has become more promising, even for this difficult case ofASLE with multiple organ damage. Thorough antepartum counseling, cautiousmaternal-fetal monitoring, and multi-organ function monitoring bymultidisciplinary specialties are keys to favorable pregnancy outcomes.

Relationship Between Clinical and Immunological Features with Magnetic Resonance Imaging Abnormalities in Female Patients with Neuropsychiatric Systemic Lupus Erythematosus

Background：Conventional magnetic resonance imaging （MRI） is the preferred neuroimaging method in the evaluation ofneuropsychiatric systemic lupus erythematosus （NPSLE）.The purpose of this study was to investigate the association between clinical and immunological features with MRI abnormalities in female patients with NPSLE,to screen for the value of conventional MRI in NPSLE.Methods：A total of 59 female NPSLE patients with conventional MRI examinations were enrolled in this retrospective study.All patients were classified into different groups according to MRI abnormalities.Both clinical and immunological features were compared between MRI abnormal and normal groups.One-way analysis of variance was used to compare the systemic lupus erythematosus disease activity index （SLEDAI） score for MRI abnormalities.Multivariate logistic regression analysis investigated the correlation between immunological features,neuropsychiatric manifestations,and MRI abnormalities.Results：Thirty-six NPSLE patients （61%） showed a variety of MRI abnormalities.There were statistically significant differences in SLEDAI scores （P 〈 0.001）,incidence of neurologic disorders （P =0.001）,levels of 24-h proteinuria （P =0.001） and immunoglobulin M （P =0.004）,and incidence of acute confusional state （P =0.002）,cerebrovascular disease （P =0.004）,and seizure disorder （P =0.028） between MRI abnormal and normal groups.In the MRI abnormal group,SLEDAI scores for cerebral atrophy （CA）,cortex involvement,and restricted diffusion （RD） were much higher than in the MRI normal group （P 〈 0.001,P =0.002,P =0.038,respectively）.Statistically significant positive correlations between seizure disorder and cortex involvement （odds ratio [OR] =14.90;95% confidence interval [CI],1.50-151.70;P =0.023） and cerebrovascular disease and infratentorial involvement （OR =10.00;95% CI,1.70-60.00;P =0.012） were found.Conclusions：MRI abnormalities in NPSLE,especially CA,cortex involvement,and RD might be markers of high systemic lupus erythematosus activity.Some MRI abnormalities might correspond to neuropsychiatric manifestations and might be helpful in understanding the pathophysiology of NPSLE.

Novasure treatment for one case of abnormal uterine bleeding with active systemic lupus erythematosus

Abnormal uterine bleeding（AUB）, especially in the menopausal transition period,is showing a tendency of rising in recent years, and after treatment, high recurrence rate for the treatment of hormone treatment, the endometrial resection and uterine resection. But for patients with severe systemic disease with AUB, it may get worse with the conventional treatment. Novasure provides us with an effective measure for the treatment of AUB with active systemic lupus erythematosus（SLE）.
