The aim of our study was to determine the effects of pregnancy on lupus and vice versa. Material and Methods: This is a retrospective study conducted over a period of 14 years from 2002 to 2015. We included cases of systemic lupus erythematosus associated with pregnancy followed at the obstetrics and gynecology department “C” of the Ibn Rochd University Hospital in Casablanca. Results: The mean age of our parturients was 31.4 years. All our patients were known to have lupus and were followed up. Pregnancy was terminated in six (20%) cases. We noted one (3%) case of intrauterine fetal death, four (13%) cases of intrauterine growth retardation, and five (16%) cases of prematurity. Lupus flare during pregnancy occurred in 16 (52%) cases, including one (3%) patient who developed superimposed pre-eclampsia, had a renal relapse in the third trimester requiring an abortion at 32 weeks of gestation with three sessions of hemodialysis, and another patient who developed eclampsia. Conclusion: A better understanding of the aggravating factors and compatible treatments has led to a more widespread authorization of pregnancy.展开更多

Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.展开更多

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease of unknown etiology that primarily affects women in adulthood. MAS is a serious condition that may be the first presentation of SLE. Here, we report the case of a 4-year-old female with MAS as the primary manifestation of Systemic Lupus Erythematosus (SLE). In this case, we outline the characteristics of a complex case of SLE that was initially accompanied with MAS, and also review the literature to discuss the clinical, biological, and therapeutic aspects of this condition.展开更多

The purpose of the study was to investigate the association between the CD4^(+)CD8^(+)double positive T(DPT) lymphocytes and LN. The study included patients with SLE without renal impairment(SLE-NRI), LN, nephritic syndrome(NS), or nephritis. Peripheral blood lymphocyte subsets were analyzed by flow cytometry. Biochemical measurements were performed with peripheral blood in accordance with the recommendations proposed by the National Center for Clinical Laboratories. The proportions of DPT cells in the LN group were significantly higher than that in the SLE-NRI group(t=4.012, P<0.001), NS group(t=3.240,P=0.001), and nephritis group(t=2.57, P=0.011). In the LN group, the risk of renal impairment increased significantly in a DPT cells proportion-dependent manner. The risk of LN was 5.136 times(95% confidence interval, 2.115–12.473) higher in cases with a high proportion of DPT cells than those whose proportion of DPT cells within the normal range. These findings indicated that the proportion of DPT cells could be a potential marker to evaluate LN susceptibility, and the interference of NS and nephritis could be effectively excluded when assessing the risk of renal impairment during SLE with DPT cell proportion.展开更多

文摘Pregnancy in women with lupus,particularly those with lupus nephritis(LN),carries an increased risk of adverse outcomes.Women with active LN at the time of conception are at a high risk of poor maternal and fetal outcomes.Recent studies indicate that even in the presence of quiescent disease,factors such as hypertension and positive lupus anticoagulant are predictors of worse pregnancy outcomes.Consequently,pre-conception evaluation is essential to ensure that pursuing pregnancy is safe and timely,and to facilitate proper planning for optimizing medical regimens,discontinuing teratogenic agents,and treating active disease.Additionally,pre-existing LN is associated with higher rates of preeclampsia and hemolysis,elevated liver enzymes,and low platelet count syndrome.Women with lupus and prior LN can have successful pregnancies,but a multidisciplinary approach with close monitoring is essential for optimal outcomes.By systematically reviewing the available evidence,this narrative review aims to provide a comprehensive update on the complex interaction between LN and pregnancy,offering insights to guide clinical practice and future research in this field.

文摘BACKGROUND In this study,we retrospectively analysed macrophage infiltration and podocyte injury in three patients with diffuse proliferative lupus nephritis(LN)who un-derwent repeated renal biopsy.CASE SUMMARY Clinical data of three diffuse proliferative LN patients with different pathological characteristics(case 1 was LN IV-G(A),case 2 was LN IV-G(A)+V,and case 3 was LN IV-G(A)+thrombotic microangiopathy)were reviewed.All patients underwent repeated renal biopsies 6 mo later,and renal biopsy specimens were studied.Macrophage infiltration was assessed by CD68 expression detected by immunohistochemical staining,and an immunofluorescence assay was used to detect podocin expression to assess podocyte damage.After treatment,Case 1 changed to LN III-(A),Case 2 remained as type V LN lesions,and Case 3,which changed to LN IV-S(A),had the worst prognosis.We observed reduced macro-phage infiltration after therapy.However,two of the patients with active lesions after treatment still showed macrophage infiltration in the renal interstitium.Before treatment,the three patients showed discontinuous expression of podocin.Notably,the integrity of podocin was restored after treatment in Case 1.CONCLUSION It may be possible to reverse podocyte damage and decrease the infiltrating ma-crophages in LN patients through effective treatment.
文摘AIM:To explore ocular surface manifestations of dry eye disease(DED)and its influencing factors in systemic lupus erythematosus(SLE)patients.METHODS:Ophthalmological examinations were conducted in SLE patients(n=43)and controls(n=41),including Ocular Surface Disease Index(OSDI),objective scatter index(OSI),tear meniscus height(TMH),lipid layer thickness(LLT),non-invasive Keratograph tear breakup time(NIKBUT),corneal fluorescein score(CFS),Schirmer I test.DED was diagnosed according to the Tear Film and Ocular Surface Society Dry Eye Workshop II Criteria.SLE patients were further divided into DED group and non-DED group,the disease activity,clinical manifestations and laboratory investigations were compared between the two groups.The disease activity was evaluated by Systemic Lupus Erythematosus Disease Activity Index 2000(SLEDAI-2K).Receiver operative characteristic(ROC)curve and multiplefactor binary logistic regression were performed.RESULTS:SLE patients showed higher OSDI[9.1(2.8-15.9)vs 6.3(2.2-7.5),P=0.035],higher OSI[1.67(1.09-2.60)vs 0.96(0.87-1.60),P=0.001],higher CFS[1(0-2)vs 0(0-1),P=0.001],lower LLT[65(42-100)vs 100(79.5-100),P=0.010],and lower NIKBUT[8.03(4.02-9.73)vs 9.67(5.26-12.71),P=0.030]than controls.The 32.6%of SLE patients had DED,which was higher than 12.2%of healthy controls.DED group showed higher SLEDAI-2K score[9.7±6.1 vs 5.4±3.4,P=0.025],higher anti-cardiolipin antibody(ACL)[8.7(3.5-13.2)vs 3.6(2.0-6.9),P=0.035],and higher proportion of patients with cutaneous eruption[42.9%vs 6.9%,P=0.015]than non-DED group.According to multiple-factor binary logistic regression analysis,the SLEDAI-2K score(OR=1.194,P=0.041)and cutaneous eruption(OR=7.094,P=0.045)could be consider as risk factors for DED in SLE patients.The ROC curve of the combined factors including age,disease duration,SLEDAI-2K score,ACL,and cutaneous eruption was analyzed,with a sensitivity of 0.786,a specificity of 0.793,and an area under curve of 0.820.CONCLUSION:Ocular surface affection is frequent in SLE patients,and patients with high disease activity and cutaneous eruption show increased risk of DED.
文摘BACKGROUND Systemic lupus erythematosus(SLE)is a chronic inflammatory disease primarily affecting young females.SLE can invade any organ,and various forms of splenic invasion have been reported.Manifestations include splenomegaly and splenic infarction,rupture,and calcification.The study encountered a rare case of splenic involvement,with nodules of various sizes without calcifications or ruptures.CASE SUMMARY A 15-year-old girl presented with arthralgia,weight loss,fever,increased levels of inflammatory markers,and positive antinuclear antibody test results.The patient was diagnosed with SLE.She was asymptomatic while taking steroids and hydroxychloroquine.Ten months after discharge,the patient developed a fever and abdominal pain.Lupus enteritis was suspected,and abdominopelvic computed tomography(AP-CT)was performed.There were no specific findings in the gastrointestinal tract,but multiple splenic nodules were observed.Infection or hemangioma was considered;however,no specific radiological findings were observed.A biopsy of the spleen was performed to determine the possibility of malignancy.The histological findings of the spleen included extensive periarteriolar necrosis with hematoxylin bodies and numerous karyorrhectic debris.Based on the biopsy results,the patient was diagnosed with an SLE flare-up and was maintained on high-dose steroids and immunosuppressants.CONCLUSION As disease activity increased,multiple nodules in the spleen that were previously unseen were observed using AP-CT and histologically confirmed.Spleen invasion by SLE can appear in multiple nodular forms and patterns.Therefore,physicians should consider these findings when differentiating these nodules from infections and malignancies.
文摘BACKGROUND Ulcerative colitis(UC)and systemic lupus erythematosus(SLE)are both systemic immunoreactive diseases,and their pathogenesis depends on the interaction between genes and environmental factors.There are no reports of UC with SLE in China,but six cases of SLE with UC have been reported in China.The combination of these two diseases has distinct effects on the pathogenesis of both diseases.CASE SUMMARY A female patient(30 years old)came to our hospital due to dull umbilical pain,diarrhea and mucous bloody stool in August 2018 and was diagnosed with UC.The symptoms were relieved after oral administration of mesalazine(1 g po tid)or folic acid(5 mg po qd),and the patient were fed a control diet.On June 24,2019,the patient was admitted for treatment due to anemia and tinnitus.During hospitalization,the patient had repeated low-grade fever and a progressively decreased Hb level.Blood tests revealed positive antinuclear antibody test,positive anti-dsDNA antibody,0.24 g/L C3(0.9-1.8 g/L),0.04 g/L C4(0.1-0.4 g/L),32.37 g/L immunoglobulin(8-17 g/L),and 31568.1 mg/24 h total 24-h urine protein(0-150 mg/24 h).The patient was diagnosed with SLE involving the joints,kidneys and blood system.Previously reported cases of SLE were retrieved from PubMed to characterize clinicopathological features and identify prognostic factors for SLE.CONCLUSION The patient was discharged in remission after a series of treatments,such as intravenous methylprednisolone sodium succinate,intravenous human immunoglobulin,cyclophosphamide injection,and plasma exchange.After discharge,the patient took oral prednisone acetate tablets,cyclosporine capsules,hydroxychloroquine sulfate tablets and other treatments for symptoms and was followed up regularly for 1 month,after which the patient's condition continued to improve and stabilize.

文摘BACKGROUND Juvenile systemic lupus erythematosus(SLE)is a severe,life-threatening disease.However,the role of rituximab in managing juvenile SLE remains undefined,although early biological intervention may improve disease outcomes.AIM To assess the differences in the outcomes of different types of rituximab administration(early and late).METHODS In this retrospective cohort study,the information of 36 children with SLE with administration(LRA)was analyzed.We compared initial disease characteristics at onset,at baseline(start of rituximab),and at the end of the study(EOS)at 12 months,as well as outcomes and treatment characteristics.RESULTS The main differences at baseline were a higher daily median dose of corticosteroids,increased MAS frequency,and a higher Systemic Lupus Erythematosus Disease Activity Index(SLEDAI)in the ERA group.No differences in the main SLE outcomes between groups at the EOS were observed.The part of lupus nephritis patients who achieved remission changed from 44%to 31%in ERA and 32%to 11%in the LRA group.Patients with ERA had a shorter time to achieve low daily corticosteroid dose(≤0.2 mg/kg)at 1.2(0.9;1.4)years compared to 2.8(2.3;4.0)years(P=0.000001)and higher probability to achieve this low dose[hazard ratio(HR)=57.8(95%confidence interval(CI):7.2-463.2),P=0.00001 and remission(SLEDAI=0);HR=37.6(95%CI:4.45-333.3),P=0.00001].No differences in adverse events,including severe adverse events,were observed.CONCLUSION ERA demonstrated a better steroid-sparing effect and a possibility of earlier remission or low disease activity,except for lupus nephritis.Further investigations are required.
文摘Introduction: Systemic lupus erythematosus is a multifactorial autoimmune disease characterised by its clinical polymorphism and its course in flares. The aim of our study was to determine the effects of pregnancy on lupus and vice versa. Material and Methods: This is a retrospective study conducted over a period of 14 years from 2002 to 2015. We included cases of systemic lupus erythematosus associated with pregnancy followed at the obstetrics and gynecology department “C” of the Ibn Rochd University Hospital in Casablanca. Results: The mean age of our parturients was 31.4 years. All our patients were known to have lupus and were followed up. Pregnancy was terminated in six (20%) cases. We noted one (3%) case of intrauterine fetal death, four (13%) cases of intrauterine growth retardation, and five (16%) cases of prematurity. Lupus flare during pregnancy occurred in 16 (52%) cases, including one (3%) patient who developed superimposed pre-eclampsia, had a renal relapse in the third trimester requiring an abortion at 32 weeks of gestation with three sessions of hemodialysis, and another patient who developed eclampsia. Conclusion: A better understanding of the aggravating factors and compatible treatments has led to a more widespread authorization of pregnancy.

文摘Systemic lupus erythematosus(SLE)is a chronic autoimmune disease in which multiple organs are damaged that prevails in fertile women.Currently,glucocorticoids and immunosuppressants are widely used to treat SLE patients.However,ovarian dysfunction occurs following the use of these drugs in women with SLE.Here,we summarize recent progress in terms of understanding ovarian injury,the effects of drug application and strategies to improve ovarian function in women with SLE.This review could be helpful to precisely cure SLE in women desiring to have offspring.
文摘Introduction: The association of systemic lupus erythematosus and rheumatoid arthritis (rhupus) is a rare clinical condition. Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.
文摘Macrophage activation syndrome (MAS), in its secondary form, often complicates rheumatic diseases but rarely constitutes a mode of revelation. Systemic lupus erythematosus (SLE) is a systemic autoimmune disease of unknown etiology that primarily affects women in adulthood. MAS is a serious condition that may be the first presentation of SLE. Here, we report the case of a 4-year-old female with MAS as the primary manifestation of Systemic Lupus Erythematosus (SLE). In this case, we outline the characteristics of a complex case of SLE that was initially accompanied with MAS, and also review the literature to discuss the clinical, biological, and therapeutic aspects of this condition.
文摘Systemic lupus erythematosus(SLE)is a multisystemic autoimmune disease characterised by the presence of autoantibodies towards nuclear antigens,immune complex deposition,and chronic inflammation at classic target organs such as skin,joints,and kidneys.Despite substantial advances in the diagnosis and management of SLE,the burden of disease remains high.It is important to appreciate the typical presentations and the diagnostic process to facilitate early referral and diagnosis for patients.In most patients,constitutional,mucocutaneous,and musculoskeletal symptoms represent the earliest complaints;these symptoms can include fatigue,lupus-specific rash,mouth ulcers,alopecia,joint pain,and myalgia.In this Seminar we will discuss a diagnostic approach to symptoms in light of the latest classification criteria,which include a systematic evaluation of clinical manifestations(weighted within each domain)and autoantibody profiles(such as anti-double-stranded DNA,anti-Sm,hypocomplementaemia,or antiphospholipid antibodies).Nonpharmacotherapy management is tailored to the individual,with specific lifestyle interventions and patient education to improve quality of life and medication(such as hydroxychloroquine or immunosuppressant)adherence.
文摘BACKGROUND Lupus mesenteric vasculitis(LMV)is a serious condition that may occur as an acute manifestation of gastrointestinal(GI)involvement and is not easily diagnosed by physicians.Delayed diagnosis and treatment of LMV may lead to rapid disease progression and can be life threatening.CASE SUMMARY A previously healthy 27-year-old woman presented with abdominal pain following a history of fatigue and consumption of cold water.Laboratory invest-igations,physical examinations,and enhanced abdominal computed tomography(CT)suggested systemic lupus erythematosus complicated by LMV.She received treatments,such as GI decompression,somatostatin,glucocorticoids,and immu-nosuppressants,and was evaluated using color ultrasonography.Twenty days later,the patient reported no stomach discomfort and was able to consume semi-liquid food.Laboratory investigations showed that inflammatory factors decreased to normal levels and complement levels increased slightly.One year after discharged,she recovered with methylprednisolone being tapered to 4 mg per day,mycophenolate mofetil to 0.75 g bid,and hydroxychloroquine to 0.2 g bid;however,only C3 complement level was slightly below the normal level.CONCLUSION Early diagnosis of LMV is essential for successful treatment;this depends on a combination of clinical manifestations,laboratory investigations,and imaging findings.Enhanced CT is preferred,but ultrasonography can be used for prompt screening and follow-up.
文摘Membranous lupus nephritis(MLN),class V,is a distinct LN characterized by immune complex deposition on subepithelial kidney biopsy.MLN is often associated with nephrotic syndrome.The histology of MLN is very similar to idiopathic(primary)membranous nephropathy(pMN).However,MLN usually has abundant mesa-glomerular deposits absent in primary membranous nephropathy.The clinical manifestations,management,and prognosis of MLN differ from other types of LN(type III,IV,or mixed type III/IV+V).Although immunosuppressive therapy is often necessary for MLN,the optimal treatment regimen is yet to be determined.This review summarizes the progress in the diagnosis and treatment of MLN and discusses the selection of immunosuppressants for MLN.

文摘Lupus nephritis(LN) has a high incidence in systemic lupus erythematosus(SLE) patients, but there is a lack of sensitive predictive markers. The purpose of the study was to investigate the association between the CD4^(+)CD8^(+)double positive T(DPT) lymphocytes and LN. The study included patients with SLE without renal impairment(SLE-NRI), LN, nephritic syndrome(NS), or nephritis. Peripheral blood lymphocyte subsets were analyzed by flow cytometry. Biochemical measurements were performed with peripheral blood in accordance with the recommendations proposed by the National Center for Clinical Laboratories. The proportions of DPT cells in the LN group were significantly higher than that in the SLE-NRI group(t=4.012, P<0.001), NS group(t=3.240,P=0.001), and nephritis group(t=2.57, P=0.011). In the LN group, the risk of renal impairment increased significantly in a DPT cells proportion-dependent manner. The risk of LN was 5.136 times(95% confidence interval, 2.115–12.473) higher in cases with a high proportion of DPT cells than those whose proportion of DPT cells within the normal range. These findings indicated that the proportion of DPT cells could be a potential marker to evaluate LN susceptibility, and the interference of NS and nephritis could be effectively excluded when assessing the risk of renal impairment during SLE with DPT cell proportion.
文摘BACKGROUND Complement overactivation is a major driver of lupus nephritis(LN).Impaired interactions of C-reactive protein(CRP)with complement factor H(CFH)have been shown as a pathogenic mechanism that contributes to the overactivation of complement in LN.However,genetic variations of neither CRP nor CFH show consistent influences on the risk of LN.AIM To examine whether genetic variations of CRP and CFH in combination can improve the risk stratification in Chinese population.METHODS We genotyped six CRP single nucleotide polymorphisms(SNPs)(rs1205,rs3093062,rs2794521,rs1800947,rs3093077,and rs1130864)and three CFH SNPs(rs482934,rs1061170,and rs1061147)in 270 LN patients and 303 healthy subjects.RESULTS No linkage was found among CRP and CFH SNPs,indicating lack of genetic interactions between the two genes.Moreover,CRP and CFH SNPs,neither individually nor in combination,are associated with the risk or clinical manifestations of LN.Given the unambiguous pathogenic roles of the two genes.CONCLUSION These findings suggest that the biological effects of most genetic variations of CRP and CFH on their expressions or activities are not sufficient to influence the disease course of LN.
文摘BACKGROUND Systemic lupus erythematosus(SLE)is a multisystem autoimmune disease that can affect the gastrointestinal tract.Most cases of lupus enteritis(LE)involve the small intestine,while the involvement of the whole colon and rectum without the small intestine being affected is extremely rare.CASE SUMMARY A 35-year-old woman was diagnosed with colorectal LE after initially presenting with intermittent abdominal pain and vomiting for two months.She had a regular medication history for five years following the diagnosis of SLE but had been irregular in taking medications,which may have contributed to the onset of LE and led to her current hospital admission.According to the 2019 Classification criteria for SLE of the European League Against Rheumatism/American College of Rheumatology,this case scored 14.Additionally,abdominal computed tomography revealed significant wall edema of the colon and rectum,ischemia and hyperemia of the ascending colon intestinal wall,mesenteric vessel engorgement,increased mesangial fat attenuation,ascites,and bilateral ureter-hydronephrosis,all indicative of colon and rectum LE.Laboratory tests also showed lower levels of complement C3 and C4,with an antinuclear antibody titer of 1:100.Overall,it was clear that this case involved the colon and rectum without affecting the small intestine,representing a rare manifestation of SLE.The patient received treatment with 10 mg of methylprednisolone sodium succinate,100 mL of 0.9%sodium chloride,hydroxychloroquine(100 mg),and nutrition support.After one week of methylprednisolone and hydroxychloroquine therapy,her SLE symptoms and disease activity improved significantly.CONCLUSION Although colorectal LE without small intestine involvement is very rare,early diagnosis and excellent management with corticosteroids prevented the need for surgical intervention.Physicians should be aware of colorectal LE without small intestine involvement as a manifestation of lupus flare.
文摘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.
