ABSTRACT
Objective To examine the predictive value of fetal umbilical artery Doppler in preterm birth in pregnant women with systemic lupus erythematosus(SLE).Methods The clinical data from 160 live births of SLE patients were analyzed retrospectively.Results The mean age of SLE patients at pregnancy was(29.7 ± 3.7) years(20 ~ 37 years). Totally,56 patients(32.5%)were preterm births and 76(47.5%)were full-term births without any other adverse pregnancy outcomes. The rate of preterm birth before 34 weeks was 26.9% and that was 73.1% for those preterm deliveries after 34 weeks. Iatrogenic preterm birth was the most common cause of preterm birth(32 cases),followed by spontaneous preterm birth(12 cases)and preterm premature rupture of membranes (10 cases).The pulsatility index(PI),resistance index(RI)as well as S/D value of SLE patients with pre-term delivery was higher than those of patients with full-term delivery(P<0.05).The area below the ROC curve for PI, RI and S/D was 0.6(95% CI 0.5~0.7),0.7(95% CI 0.6~0.8)and 0.6(95% CI 0.5~0.7),respectively.PI with cut-off value of 1.0 indicated the highest risk of preterm birth,with sensitivities of 34.6% and 84.2.The optimal cut-off value for RI and S/D was 0.7 and 2.8 respectivly,at which sensitivity and specificity had the best combination. Conclusions Pregnancies in lupus still have an increased risk of preterm birth. Umbilical artery Doppler was a useful monitoring tool for preterm birth in lupus pregnancies.
ABSTRACT
Objective To investigate the characteristics of bone marrow examination in systemic lupus erythematosus (SLE) patients with blood system damage.Methods The data of 150 SLE patients with bone marrow puncture were analyzed retrospectively.Results Of the 150 patients,68 patients had abnormalities in bone marrow examination.Common bone marrow abnormalities were low proliferative bone marrow (26 cases,38.2％),hemophagocytic (17 cases,25％),pure red blood cells aplastic anemia (6 cases,8.8％),aplastic anemia (12 cases,17.6％) and decreased megakaryocyte count (7 cases,10.4％).10 cases of severe and severe anemia (90.9％ of patients with severe and severe anemia) and 21 patients with severe thrombocytopenia (67.7％ of patients with severe thrombocytopenia) had abnormal bone marrow examination.Conclusions It is not uncommon for SLE patients to have abnormal bone marrow examination.When the peripheral blood test is found to be severe anemia or severe thrombocytopenia,bone marrow aspiration and bone marrow biopsy are needed.
ABSTRACT
Objective To describe the characteristics and risk factors for Mycobacterium tuberculosis (TB)infection in patients with systemic lupus erythematosus(SLE).Methods A retrospective analysis was per-formed. Results Among our sample of 784 hospitalized patients,42(5.4%)were diagnosed with TB infection. Seventeen were pulmonary TB,11 were pulmonary and extra-pulmonary TB and 14 were extra-pulmonary TB.hest X-rays showed Abnormal chest imaging was observed in 34 cases,among which,19 were multi-lobar involvements and 9 were single-lobe involvements. Logistic regression multivariate analysis indicated that anemia and the daily mean dose of glucocorticoid(GC)were associated with TB. Conclusions Manifestations of TB in SLE patients were atypical.Anemia and the daily mean dose of GC were associated with TB.
ABSTRACT
Objective To explore the relationship between Adult-onset Still's disease (AOSD) and macrophage activation syndrome (MAS). Methods A total of 78 patients with AOSD who had completed medical information were included in this study. Eleven patients who were diagnosed as rheumatic disease associated hemophagocytic syndrome among 26 patients who had hemophagocytic syndrome with histological evidence consisted of the MAS group. Clinical and laboratory data were analyzed in 78 patients with AOSD and 11 patients with MAS. Results Among 78 cases of AOSD, 9 patients (12%) could be diagnosed as MAS but didn't have hemophagocytic histological evidence. In the 11 MAS cases with hemophagocytic phenomenon, 6 patients fulfilled the diagnostic criteria of AOSD, 2 cases with panniculitis, 1 case with SLE, 1 case of dermatomyositis and 1 case of systemic vasculitis. Logistic analysis showed that splenomegaly (OR =2.13, 95%CI=1.11-3.42), leukopenia (OR=3.57, 95%CI=2.30～4.86), anaemia (OR=0.85, 95%CI=1.03～2.76), thrombocytopenia (OR=2.98, 95%CI=1.17-4.30) and hypertriglyceridemia (OR=1.66, 95%CI=1.02～2.74) were associated with development of MAS in AOSD. Conclusion The development of MAS in AOSD patient is frequent and hemophagocytic histological evidence could be found in severe cases. When splenomegaly and hypocytomsis present in AOSD patients, bone marrow examination should be done and the level of triglyceride and fibrinogen and activity of NK cells should be measured for early diagnosis.
ABSTRACT
Objective To explore the efficacy of tumor necrosis factor inhibitor in hip joint lesion of ankylosing spondylids (AS). Methods Eight-six patients with hip joint lesion of ankylosing spondylitis were Enrolled in this study. The treatment protocol was: ①Etanercept 25 mg was suncutaneously injected twice a week in the first two months and once a week in the following two months. Then it was injected once every oth-er two weeks in the last two months of the study period.②Methotrexate 15 mg was administered orally or in-travenously once a week.③NSAIDs and prednisone were stopped when symptoms sunsides. Results Twenty-eight cases (33%) stopped NSAIDs because of the disappearance of symptoms in 2 weeks after starting of the study. Forty-three (50%) stopped NSAIDs with in 8 weeks and 36 cases (42%) in them stopped NSAIDs and prednisone. During the 9th and 16th week, etanercept was used once a week and 49 cases (60%) stopped NSAIDs and prednisone. During the 17th and 24th week, etanercept was used once every two weeks, and 38 cases (44%) stopped NSAIDs and prednisone and their disease was stable. Hip Functional Scores of patients were elevated significantly at 2, 4 and 6 months after the treatment (p<0.05) BASDAI and BASFI decreased, and the difference was significant when compared to those before the treatment (P<0.05). For the 19 cases with hip joint synovitis and hydrarthrosis in MRI image but without obvious change in pelvic plain films, syn-ovitis of 11 cases disappeared and 4 cases improved significantly. In 84 hip joints with grade Ⅱ or Ⅲ changes, 13 joints improved for one grade, 16 joints had improvement but less than one grade, and 49 joints had no radiological changes. Conclusion Etanercept, when combined with methotrexate, is effective in treat-ing hip joint lesion of ankylosing spondylitis. The dosage of etanercept can be tapered after the disease is un-der control.
ABSTRACT
AIM: To determine the expression of membrane-bound B lymphocyte stimulator((BLyS)) and its mRNA in peripheral blood mononuclear cells(PBMCs) from individuals with systemic lupus erythematosus(SLE),and to investigate the effect of dexamethasone on(BLyS) expression.METHODS: PBMCs were obtained from 25 individuals with SLE(mean age of 31.40?14.23) and 20 female healthy volunteers(mean age of 28.20?10.36).They were randomized into dexamethasone((1 ?mol/L)) group and media group.PBMCs were gathered at 0,6,12 and 24 h for(BLyS) mRNA assessment using reverse transcription-PCR(RT-PCR).PBMCs were also collected at 72 h for membrane-bound(BLyS) protein detection using flow cytometry(FACS) and direct immunofluorescence.RESULTS:(1) The expression of(BLyS) mRNA and membrane-bound protein were significantly higher in PBMCs from individuals with SLE than that in PBMCs from healthy controls(0.40?0.18 vs 0.27?0.20,P
