Systemic-Lupus-Erythematosus-Related Acute Pancreatitis: A Cohort from South China

Acute pancreatitis (AP) is a rare but life-threatening complication of SLE. The current study evaluated the clinical characteristics and risk factors for the mortality of patients with SLE-related AP in a cohort of South China. Methods. Inpatient medical records of SLE-related AP were retrospectively reviewed. Results. 27 out of 4053 SLE patients were diagnosed as SLE-related AP, with an overall prevalence of 0.67%, annual incidence of 0.56‰ and mortality of 37.04%. SLE patients with AP presented with higher SLEDAI score (21.70 ± 10.32 versus 16.17 ± 7.51, P = 0.03), more organ systems involvement (5.70 ± 1.56 versus 3.96 ± 1.15, P = 0.001), and higher mortality (37.04% versus 0, P = 0.001), compared to patients without AP. Severe AP (SAP) patients had a significant higher mortality rate compared to mild AP (MAP) (75% versus 21.05%, P = 0.014). 16 SLE-related AP patients received intensive GC treatment, 75% of them exhibited favorable prognosis. Conclusion. SLE-related AP is rare but concomitant with high mortality in South Chinese people, especially in those SAP patients. Activity of SLE, multiple-organ systems involvement may attribute to the severity and mortality of AP. Appropriate glucocorticosteroid (GC) treatment leads to better prognosis in majority of SLE patients with AP

Fetal outcomes and associated factors of adverse outcomes of pregnancy in southern Chinese women with systemic lupus erythematosus.

This study aims to investigate the fetal outcomes and associated factors of adverse pregnancy outcomes (APOs) in pregnant women with systemic lupus erythematosus (SLE). Clinical data from 251 SLE patients with 263 pregnancies from 2001 to 2015 were analyzed retrospectively. APOs occurred in 70.0% of pregnancies, in which pregnancy loss occurred in 28.5%; preterm delivery occurred in 21.3%; intrauterine growth retardation occurred in 12.2%; and fetal distress occurred in 8.0%. Over time, the rate of APOs decreased from 82.8% during 2001~2005 to 59.6% during 2011~2015. In multivariate analysis, predictors of APOs included positive antiphospholipid antibodies (OR 8.4, 95% CI 1.7~40.8, P = 0.008), lower complement (OR 3.6, 95% CI 1.3~9.9, P = 0.01), hypoalbuminemia (OR 3.2, 95% CI 1.2~8.3, P = 0.02), and hypertension (OR 14.6, 95% CI 1.5~141.6, P = 0.02). The use of antimalarial medications was associated with lower risk for APOs (OR 0.3, 95% CI 0.1~0.7, P = 0.01). In total, 109 patients underwent fetal umbilical artery Doppler in the third trimester. The The adjusted systole/diastole (S/D) ratio, pulsatility index (PI) and resistance index (RI) of SLE patients with APOs were higher than that of patients without APOs (2.9±0.9 vs. 2.4±0.5, P = 0.001). Lupus pregnancy was still at high risk of APOs in terms of pregnancy loss and preterm delivery. Umbilical artery Doppler was a good monitor method for APOs in the third trimester

Fetal and Maternal Outcomes of Planned Pregnancy in Patients with Systemic Lupus Erythematosus: A Retrospective Multicenter Study

Objective. To investigate the fetal and maternal outcomes as well as predictors of APOs in women with SLE who conceived when the disease was stable, the so-called “planned pregnancy.” Methods. A retrospective multicenter study of 243 patients with SLE who underwent a planned pregnancy was performed. APOs in fetus and mothers were recorded. Results. The average age at conception was 28.9 ± 3.9 years. Duration of SLE prior to pregnancy was 4.4 ± 4.3 years. Fetal APOs occurred in 86 (86/243, 35.4%) patients. Preterm births, intrauterine growth retardation (IUGR), fetal distress, and fetal loss accounted for 22.2%, 14.8%, 11.1%, and 4.9%, respectively. Forty-two preterm infants (42/54, 77.8%) were delivered after the 34th week of gestation. All the preterm infants were viable. Fifty-two patients (52/243, 21.4%) had disease flares, among which 45 cases (45/52, 86.5%) were mild, 6 (6/52, 11.5%) were moderate, and 1 (1/52, 1.9%) was severe. Disease flares were mainly presented as active lupus nephritis (41/52, 78.8%), thrombocytopenia (10/52, 19.2%), and skin/mucosa lesions (9/52, 17.3%). Pregnancy-induced hypertension (PIH) occurred in 29 patients, among which 3 were gestational hypertension and 26 were preeclampsia. Multiple analysis showed that disease flares (OR, 8.1; CI, 3.8–17.2) and anticardiolipin antibody positivity (OR, 7.4; CI, 2.5–21.8) were associated with composite fetal APOs. Conclusion. Planned pregnancy improved fetal and maternal outcomes, presenting as a lower rate of fetal loss, more favorable outcomes for preterm infants, and less severe disease flares during pregnancy

Invasive mycoses in patients with connective tissue disease from Southern China: clinical features and associated factors

Abstract Background A retrospective study was performed to investigate the clinical features and associated factors of invasive mycoses (IM) in patients with connective tissue disease (CTD) from Southern China. Methods Demographic and clinical data were recorded. Associated factors were analyzed by logistic regression analysis. Results A total of 6911 patients with CTD were included. IM was diagnosed in 32 patients (incidence, 0.5%). IM was predominant in patients with ANCA-associated vasculitis (AAV) (incidence, 1.5%, 7/480). Lung was commonly involved (30/32, 93.8%). Aspergillus spp. (81.3%) were the leading strain. The positive rate of fungi detection in sputum culture was 69.0%. Serum galactomannan (GM) test was positive in bronchoalveolar lavage fluid (BALF) from seven (7/10, 70.0%) patients. Ten patients died (31.3%), including three with AAV (42.9%) and seven with SLE (36.8%). Penicillium marneffei was the most fatal (mortality, 100%). Non-survivors had higher prevalence of leukopenia (30.0% vs 4.5%, P = 0.04), lymphopenia (100.0% vs 59.1%, P = 0.02), elevated serum creatinine (70.0% vs 27.3%, P = 0.02), and co-infection (70.0% vs 18.2%, P = 0.004) than survivors. Multivariate logistic regression analysis showed that lymphopenia [odds ratio (OR) = 3.28, 95% confidence interval (CI) 1.29–8.38, P = 0.01] and median-to-high dose of glucocorticoid (GC) [OR = 3.40, 95% CI 1.04–11.13, P = 0.04] were associated with IM in patients with CTD. Conclusions IM tended to develop in patients with AAV, resulting in high mortality. Sputum culture and GM test in BALF were effective methods to distinguish IM. Vigilance against lymphopenia, impaired kidney function, and co-infection improved the prognosis of IM

Porphyrazines with Annulated Diazepine Rings. 2. Alternative Synthetic Route to Tetrakis-2,3-(5,7-diphenyl-1,4-diazepino)porphyrazines: New Metal Complexes, General Physicochemical Data, Ultraviolet−Visible Linear and Optical Limiting Behavior, and Electrochemical and Spectroelectrochemical Properties

Following a previous report on the synthesis and physicochemical characterization of a novel class of porphyrazines carrying peripherally annulated seven-membered rings, i.e., tetrakis-2,3-(5,7-diphenyl-1,4-diazepino)porphyrazine [Ph8DzPzH2]·4H2O and its metal derivatives [Ph8DzPzM]·xH2O (x = 2−7, M = MgII(H2O), CuII, and ZnII), a new more convenient procedure is reported here, allowing the preparation in high yields of the LiI and NaI derivatives of formulas [Ph8DzPzLi2]·5H2O and [Ph8DzPzNa2]·6H2O, which can be directly converted into other metal derivatives under mild conditions (room temperature) and in good yields. The series studied has been extended to include the MnII and CoII complexes also reported here for the first time. Physicochemical characterization of the new “diazepinoporphyrazines” was based on fast atom bombardment (FAB) mass spectrometry and X-ray powder patterns, infrared (IR), electron paramagnetic resonance (EPR), and room-temperature magnetic susceptibility measurements. A detailed discussion of the UV−vis spectra emphasizes the role played by the external diazepine rings in electron delocalization through their tautomeric or protonated forms present in neutral, basic, and acidic media. The nonlinear optical effect of optical limiting for the different species [M = 2H, MgII(H2O), MnII, CoII, CuII, and ZnII] has also been measured. It has been observed that the extent of the optical limiting depends on the specific M center. The observed nonlinear optical features are analyzed and discussed in terms of the electronic and magnetic properties exhibited by some of the metal ions and taking into account the model of the excited-state absorption in which the nature of M determines the kinetics of formation of the highly absorbing state of the specific complex examined. As evidenced by the detailed electrochemical and spectroelectrochemical study carried out on this new class of macrocycles, one of the most important aspects is the facilitated electron delocalization for the oxidized and reduced species allowed by a 1H−6H tautomerism taking place on the peripheral diazepine rings
