Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease that affects multiple organs and systems. It is more common in women of childbearing age. Compared with the general population, pregnant women with SLE are at a significantly increased risk of adverse perinatal outcomes such as preterm birth and intrauterine growth restriction. In addition, the offspring of SLE patients may also be adversely affected by in utero exposure to maternal autoantibodies, cytokines, and drugs. This article summarizes the long-term developmental outcomes of offspring of pregnant women with SLE in terms of the blood system, circulatory system, nervous system, and immune system.

OBJECTIVE: To investigate the fetal and maternal outcomes, risk factors of disease progression and adverse pregnancy outcomes (APOs) in patients with undifferentiated connective tissue disease (UCTD). METHODS: This retrospective study described the outcomes of 106 pregnancies in patients with UCTD. The patients were divided into APOs group (n=53) and non-APOs group (n=53). The APOs were defined as miscarriage, premature birth, pre-eclampsia, premature rupture of membranes (PROM), intrauterine growth restriction (IUGR), postpartum hemorrhage (PPH), and stillbirth, small for gestational age infant (SGA), low birth weight infant (LBW) and birth defects. The differences in clinical manifestations, laboratory data and pregnancy outcomes between the two groups were compared. Logistic regression analysis was performed to analyze the risk factors for APOs and the progression of UCTD to definitive CTD. RESULTS: There were 99 (93.39%) live births, 4 (3.77%) stillbirths and 3 (2.83%) miscarriage, 20 (18.86%) preterm delivery, 6 (5.66%) SGA, 17 (16.03%) LBW, 11 (10.37%) pre-eclampsia, 7 (6.60%) cases IUGR, 19 (17.92%) cases PROM, 10 (9.43%) cases PPH. Compared with the patients without APOs, the patients with APOs had a higher positive rate of anti-SSA antibodies (73.58% vs. 54.71%, P=0.036), higher rate of leukopenia (15.09% vs. 3.77%, P=0.046), lower haemoglobin level [109.00 (99.50, 118.00) g/L vs. 124.00 (111.50, 132.00) g/L, P < 0.001].Multivariate Logistic regression analysis showed that leucopenia (OR=0.82, 95%CI: 0.688-0.994) was an independent risk factors for APOs in UCTD (P=0.042). Within a mean follow-up time of 5.00 (3.00, 7.00) years, the rate of disease progression to a definite CTD was 14.15%, including 8 (7.54%) Sjögren's syndrome, 4 (3.77%) systemic lupus erythematosus (SLE), 4 (3.77%) rheumatoid arthritis and 1 (0.94%) mixed connective tissue disease. Multivariate Cox proportional risk regression analysis showed that Raynaud phenomenon (HR=40.157, 95%CI: 3.172-508.326) was an independent risk factor for progression to SLE. CONCLUSION Leukopenia is an independent risk factor for the development of APOs in patients with UCTD. Raynaud's phenmon is a risk factor for the progression of SLE. Tight disease monitoring and regular follow-up are the key measures to prevent adverse pregnancy outcomes and predict disease progression in UCTD patients with pregnancy.

Systemic lupus erythematosus (SLE) associated macrophage activation syndrome (MAS) is clinically severe, with a high mortality rate and rare neuropsychiatric symptoms. In the course of diagnosis and treatment, it is necessary to actively determine whether the neuropsychiatric symptoms in patients are caused by neuropsychiatric systemic lupus erythematosus (NPSLE) or macrophage activation syndrome. This paper retrospectively analyzed the clinical data of 2 cases of SLE associated MAS with neuropsychiatric lesions, Case 1: A 30-year-old female had obvious alopecia in 2019, accompanied by emaciation, fatigue and dry mouth. In March 2021, she felt weak legs and fell down, followed by fever and chills without obvious causes. After completing relevant examinations, she was diagnosed with SLE and given symptomatic treatments such as hormones and anti-infection, but the patient still had fever. The relevant examinations showed moderate anemia, elevated ferritin, elevated triglycerides, decreased NK cell activity, and a perforin positivity rate of 4.27%, which led to the diagnosis of "pre-hemophagocytic syndrome (HPS)". In May 2021, the patient showed mental trance and babble, and was diagnosed with "SLE-associated MAS"after completing relevant examinations. After treatment with methylprednisolone, anti-infection and psychotropic drugs, the patient's temperature was normal and mental symptoms improved. Case 2: A 30-year-old female patient developed butterfly erythema on both sides of the nose on her face and several erythema on her neck in June 2019, accompanied by alopecia, oral ulcers, and fever. She was diagnosed with "SLE" after completing relevant examinations, and her condition was relieved after treatment with methylprednisolone and human immunoglobulin. In October 2019, the patient showed apathy, no lethargy, and fever again, accompanied by dizziness and vomiting. The relevant examination indicated moderate anemia, decreased NK cell activity, elevated triglycerides, and elevated ferritin. The patient was considered to be diagnosed with "SLE, NPSLE, and SLE-associated MAS". After treatment with hormones, human immunoglobulin, anti-infection, rituximab (Mabthera), the patient's condition improved and was discharged from the hospital. After discharge, the patient regularly took methylprednisolone tablets (Medrol), and her psychiatric symptoms were still intermittent. In November 2019, she developed symptoms of fever, mania, and delirium, and later turned to an apathetic state, and was given methylprednisolone intravenous drip and olanzapine tablets (Zyprexa) orally. After the mental symptoms improved, she was treated with rituximab (Mabthera). Later, due to repeated infections, she was replaced with Belizumab (Benlysta), and she was recovered from her psychiatric anomalies in March 2021. Through the analysis of clinical symptoms, imaging examination, laboratory examination, treatment course and effect, it is speculated that the neuropsychiatric symptoms of case 1 are more likely to be caused by MAS, and that of case 2 is more likely to be caused by SLE. At present, there is no direct laboratory basis for the identification of the two neuropsychiatric symptoms. The etiology of neuropsychiatric symptoms can be determined by clinical manifestations, imaging manifestations, cerebrospinal fluid detection, and the patient's response to treatment. Early diagnosis is of great significance for guiding clinical treatment, monitoring the condition and judging the prognosis. The good prognosis of the two cases in this paper is closely related to the early diagnosis, treatment and intervention of the disease.

OBJECTIVE: To explore the changes of Ⅻ antithrombin (FⅫa-AT), thrombospondin-1 (TSP-1), and lupus anticoagulant (LA) ratio in the peripheral blood factor of patients with systemic lupus erythematosus (SLE) and the clinical value of combined diagnosis of thrombotic events. METHODS: A total of 133 SLE patients treated in Xingtai People's Hospital were selected and divided into simple SLE group (105 cases) and SLE complicated with thrombosis group (28 cases) according to whether thrombotic events occurred, and 102 cases of healthy people in the same period were selected as control. The clinical data of the 3 groups, the level of peripheral blood FⅫa-AT, TSP-1, and LA ratio were compared, the relationship between each peripheral blood index and SLE disease activity index (SLEDAI) score were analyzed. The influencing factors of thrombotic events in SLE patients were analyzed, and the value of each peripheral blood index in the diagnosis of SLE complicated with thrombotic events were evaluated. RESULTS: The proportion of the patients with age ≥60 year, hypertension, and smoking history in SLE complicated with thrombosis group was higher than those in simple SLE group and control group (P＜0.05). The SLEDAI score, peripheral blood FⅫa-AT, TSP-1, LA ratio levels of the patients in SLE complicated with thrombosis group were significantly higher than those in simple SLE group and control group, and the simple SLE group was significantly higher than the control group (P＜0.05). FⅫa-AT, TSP-1, LA ratio in peripheral blood of SLE patients were positively correlated with SLEDAI score (r=0.663, 0.578 and 0.625). Age, blood pressure, smoking history, peripheral blood FⅫa-AT, TSP-1, LA ratio were the important influencing factors of thrombotic events in SLE patients (P＜0.05). The AUC diagnosed by the FⅫa-AT, TSP-1, and LA ratio in peripheral blood was 0.881, the 95% CI was 0.813-0.931, the sensitivity was 82.14%, and the specificity was 91.43%, which was superior to each index alone (P＜0.05). CONCLUSION Peripheral blood FⅫa-AT, TSP-1, LA ratio level changes in SLE patients are significantly related to disease activity, and the combined diagnosis of thrombotic events is more reliable.

OBJECTIVE: To build bridges between anti-α enolase antibody (anti-enolase 1 antibody, anti-ENO1 antibody) and common clinical and laboratory characteristics of systemic lupus erythematosus (SLE) and to analyze the role of anti-ENO1 antibody in the evaluation of SLE disease activity. METHODS: The SLE patients with retinopathy and without retinopathy were enrolled in the study, as well as healthy individuals whose gender and age matched with those of the SLE patients. Serum anti-ENO1 antibodies were measured using enzyme-linked immunosorbent assay (ELISA), presenting as intra-group positive rate and arbitrary units (AU) value. Clinical and laboratory data were obtained from medical records. RESULTS: The SLE retinopathy patients represented various fundus abnormalities. Ranked by percentage, the top three retinopathies were retinal hemorrhage (14/32, 43.75%), cotton-wool spots (8/32, 25.00%) and retinal vein occlusion (3/32, 9.38%). Among the 32 SLE retinopathy patients, 13 (40.63%) suffered from two or more fundus abnormalities. The positive rate and AU value of the SLE patients were higher than of the SLE patients without retinopathy (68.75% vs. 46.00%, P=0.043; 16.11%±10.35% vs. 12.06%±6.47%, P=0.045). Besides, the positive rate and AU value of the two SLE groups were both significantly higher than those of the healthy control group (P < 0.001). Compared with the SLE-without-retinopathy group, the systemic lupus erythematosus disease activity index (SLEDAI)-2000 of the SLE retinopathy patients were significantly higher than those of the SLE patients without retinopathy (17.41±4.25 vs. 9.48±5.35, P < 0.001). Dividing all the SLE patients into an anti-ENO1-positive group and an anti-ENO1-negative group, we found that anti-ENO1-positive was more likely to be correlated to developing fever and positive result of urine occult blood (P=0.011, P=0.042). Comparing with the patients with negative anti-ENO1 antibodies, the patients with positive anti-ENO1 antibodies had significantly higher erythrocyte sedimentation rate (ESR) [the median (range) was 29.50 (1.52-110.00) mg/L vs. 12.00 (4.00-101.00) mg/L, P=0.001], higher immunoglobulin G (IgG) [the median (range) was 14.30 (4.02-37.80) g/L vs. 10.46 (2.50-25.73) g/L, P=0.000 3], and higher blood platelet count (PLT) [(205.87×10⁹±67.98×10⁹) /L vs. (164.57×10⁹±69.57×10⁹) /L, P=0.008], as well as higher immunoglobulin A (IgA) [the median (range) was 2.85 (0.07-27.00) g/L vs. 2.05 (0.42-4.36) g/L, P=0.014]. CONCLUSION The positive rate and AU value of anti-ENO1 antibody suggested higher SLE disease activity and they were elevated in SLE and SLE retinopathy.

OBJECTIVE: To investigate the clinical features, radiologic scores and clinically relevant risk factors prognosis of secondary interstitial lung disease (ILD) in patients with systemic lupus erythematosus (SLE). METHODS: In this study, 60 SLE patients in Department of Rheumatology of the First Affiliated Hospital of Baotou Medical College and Taizhou First People's Hospital from January 2015 to March 2019 were retrospectively analyzed. All of those 60 patients with SLE underwent lung high resolution computed tomography (HRCT) examination. We used a 1 ∶1 case-control study. There was a matching of age and gender between the two groups. Thirty patients with SLE related ILD (SLE-ILD) were in the case group, and 30 patients with SLE without ILE (SLE non-ILD) were in the control group. The clinical features, pulmonary function test, radiologic characteristic of SLE patients were collected and were used to analyze SLE-ILD. RESULTS: In this study, we reached the following conclusions: First, there were statistically significant differences in chest tightness/shortness of breath, Raynaud's phenomenon, and Velcro rale between SLE-ILD and SLE non-ILD patients (both P < 0.05); Second, hemoglobin (Hb) and albumin (ALB) in the patients of SLE-ILD had a significant decrease compared with the patients of SLE non-ILD. Blood urea nitrogen (BUN), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) increased in SLE-ILD patients compared with SLE non-ILD patients, the difference had statistical significance (P < 0.05); Third, for SLE-ILD patients, the most common type was non-specific interstitial pneumonia (NSIP), followed by usual interstitial pneumonia and lymphocytic interstitial pneumonia; Fourth, there was no significant difference in clinical-radiology-physiology scores between the different ILD types (P>0.05), similarly, the lung HRCT score and lung function between different ILD types had no significant difference (P>0.05); Fifth, multivariate Logistic regression analysis showed that decreased albumin and chest tightness/shortness of breath might be the risk factor for SLE-ILD. CONCLUSION There are statistically significant differences between the SLE-ILD group and SLE non-ILD group in terms of chest tightness/shortness of breath, Velcro rale and Raynaud's phenomenon. Decreased albumin and chest tightness/shortness of breath in SLE patients should be alerted to the occurrence of ILD. NSIP is the most common manifestation of SLE-ILD.

OBJECTIVE: To measure the level of serum Semaphorin 3A (Sema3A) and to analyze the relationship between serum Sema3A and systemic lupus erythematosus (SLE) with thrombocytopenia. METHODS: The concentration of serum Sema3A was detected by enzyme-linked immuno sorbent assay (ELISA) in 170 SLE patients, 50 Sjögren's syndrome (SS) patients, 19 hypersplenism (HS) patients and 150 healthy controls (HC). Based on the presence of thrombocytopenia and whether the thrombocytopenia was in remission, the SLE patients were divided into three groups: SLE with thrombocytopenia (41 cases), SLE with thrombocytopenia remission (28 cases), and SLE without thrombocytopenia (101 cases). According to whether there was thrombocytopenia, the SS patients were divided into SS with thrombocytopenia (18 cases) and SS without thrombocytopenia (32 cases). The 28 SLE patients who underwent bone marrow aspiration biopsy were divided into two groups from the aspect of whether the bone marrow hyperplasia was normal (19 cases) or low (9 cases), as well as from the aspect of whether the maturity disturbance of megakaryocyte was positive (8 cases) or negative (20 cases). The serum Sema3A levels in SLE, SS, HS with HC were compared, meanwhile, the correlation between serum Sema3A level and platelet (PLT) in the patients with different diseases analyzed. RESULTS: (1) Serum Sema3A levels in SLE were significantly lower than in HC [(3.84±2.76) μg/L vs. (6.96±2.62) μg/L, P < 0.001], serum Sema3A levels in SS were also obviously lower than in HC [(4.35±3.57) μg/L vs. (6.96±2.62) μg/L, P < 0.001], and in HS it was lower than HC at a certain extant [(5.67±2.26) μg/L vs. (6.96±2.62) μg/L, P=0.041]. (2) Serum Sema3A levels in SLE were slightly lower than in SS, but there was no significant difference [(3.84±2.76) μg/L vs. (4.35±3.57) μg/L, P=0.282]. However, when compared with HS, serum Sema3A levels in SLE were significantly lower [(3.84±2.76) μg/L vs. (5.67±2.26) μg/L, P=0.006]. (3) Serum Sema3A concentration in SLE with thrombocytopenia was significantly lower than in SLE with thrombocytopenia remission [(1.28±1.06) μg/L vs. (3.83±2.65) μg/L, P < 0.001], and in SLE patients without thrombocytopenia [(1.28±1.06) μg/L vs. (4.87±2.60) μg/L, P < 0.001]. There was no significant difference between SLE with thrombocytopenia remission and SLE without thrombocytopenia [(3.83±2.65) μg/L vs. (4.87±2.600 μg/L, P=0.123]. Serum Sema3A concentration in SLE with thrombocytopenia was slightly lower than in SS with thrombocytopenia, but there was no significant difference [(1.28±1.06) μg/L vs. (1.68±1.11) μg/L, P=0.189]. (4) Strong positive correlations were found between serum Sema3A and PLT in SLE (r=0.600, P < 0.001). Positive correlations were also found between serum Sema3A and PLT in SS (r=0.573, P < 0.001). However, there was no such correlation showed in HS patients (P=0.393). (5) There was no significant difference of serum Sema3A concentration in SLE whether the bone marrow hyperplasia was normal or low. And the same situation appeared in the patients whether the maturity disturbance of megakaryocyte was positive or negative (P>0.05). CONCLUSION Serum Sema3A was significantly reduced in SLE patients, and it was highly correlated with the blood damage. Similar conclusions could be drawn in patients with SS. The serum level of Sema3A was generally decreasing in desmosis which merged thrombocytopenia, and was obviously positive correlated with platelet counts.
