Predictors of SLE relapse in pregnancy and post-partum among multi-ethnic patients in Malaysia

Pregnancy outcomes and risk factors analysis in patients with systemic lupus erythematous

BACKGROUND

The management of systemic lupus erythematosus (SLE) during pregnancy remains a challenge currently. Identifying early predictors of adverse pregnancy outcomes in SLE patients can help to develop treatment plan and improve prognosis. The aim of this study is to explore the clinical and laboratory variables in the early pregnancy that can predict adverse neonatal and maternal outcomes, thereby facilitating the grading management of SLE.

METHODS

A retrospective analysis was conducted on 126 pregnant women with SLE who were admitted to Zhongnan Hospital of Wuhan University between January 2017 and December 2022. All enrolled patients were diagnosed (including newly diagnosed and previously diagnosed) during first trimester of pregnancy and their clinical records, laboratory results and pregnancy outcomes were reviewed. The association between the clinical and laboratory characteristics of patients at 12 gestational age and the adverse neonatal (ANOs) as well as maternal outcomes (AMOs) were analyzed.

RESULTS

A total of 117 live births (92.8%) were recorded in the study. ANOs occurred in 59 (46.8%) cases, including fetal loss in 9 cases (7.1%), preterm birth in 40 cases (31.7%), small for gestational (SGA) in 15 cases (11.9%), and complete heart block in 2 cases (1.5%). Univariate analysis showed that disease activity index (P < 0.0001), lupus nephritis (P = 0.0195), anti-SSB positivity (P = 0.0074) and hypocomplementemia (P = 0.0466) were related to ANOs. However, multivariate analysis showed that only disease activity during early pregnancy was an independent predictor for ANOs (OR = 7.053, 95% CI: 1.882 to 26.291, P = 0.004). In addition, 48 patients experienced AMOs during subsequent trimester, including 24 (19.0%) patients with disease flare and 23 (18.3%) patients with pre-eclampsia. Unplanned pregnancy (P = 0.010), active disease (P = 0.0004), new onset SLE (P = 0.0044) and lupus nephritis (P = 0.0009) were associated with AMOs in univariate analysis, while disease activity was identified as an independent risk factor for AMOs (OR = 2.553, 95% CI: 1.012-6.440, P = 0.047).

CONCLUSION

Active disease in early pregnancy is associated with adverse pregnancy outcomes. For patients with high risk factor for ANOs and AMOs, more intensive treatment and follow-up should be a wise measure. Especially for those who suffer from active disease, they should be fully informed and given the option to terminate or continue their pregnancy.

Lupus nephritis: management challenges during pregnancy

Lupus nephritis (LN), a severe complication of systemic lupus erythematosus (SLE), leads to significant kidney inflammation and damage and drastically increases mortality risk. Predominantly impacting women in their reproductive years, LN poses specific risks during pregnancy, including pre-eclampsia, growth restrictions, stillbirth, and preterm delivery, exacerbated by lupus activity, specific antibodies, and pre-existing conditions like hypertension. Effective management of LN during pregnancy is crucial and involves carefully balancing disease control with the safety of the fetus. This includes pre-conception counseling and a multidisciplinary approach among specialists to navigate the complexities LN patients face during pregnancy, such as distinguishing LN flare-ups from pregnancy-induced conditions. This review focuses on exploring the complex dynamics between pregnancy and LN, emphasizing the management difficulties and the heightened risks pregnant women with LN encounter.

Epstein-Barr virus reactivation and disease flare of systemic lupus erythematosus

SLE affects females rather than males with a ratio of about 9:1. Owing to the high morbidity with multiple organ involvement, SLE flare-up remains a challenge for women's health. In an accumulation of the past 70 years of studies globally, EBV has been found to be strongly associated with SLE. In the past two decades, EBV reactivation has been proven as prevalent in SLE patients as well as being strongly associated with higher SLE activity and higher prevalence of SLE flare. Hence, strategies to control EBV reactivation in SLE including pharmacological (such as Tenofovir prodrugs TDF and TAF) and non-pharmacological approaches are being developed. The heterogeneity of SLE constitutes clinical challenges, suggesting a stratification of SLE into subgroups based on EBV reactivation or non-reactivation is reasonable. Future-wise, adding anti-EBV reactivation medication to current immunosuppressants for the subgroup of SLE patients with EBV reactivation could be beneficial to achieve long-term remission of SLE.

Risks and outcomes of pregnancy in neuromyelitis optica spectrum disorder: A comprehensive review

Neuromyelitis optica spectrum disorder (NMOSD) is a rare central nervous system autoimmune disease. Aquaporin-4 antibody (AQP4-IgG) is present in over 75% of cases and criteria also exist for the diagnosis of seronegative NMOSD. AQP4-IgG NMOSD has a strong female predominance (9:1 ratio), with a median onset age of 40 years. Pregnancy in those with NMOSD is therefore an important topic. Fecundity in NMOSD is likely impaired, and for females who conceive, obstetric complications including miscarriages and pre-eclampsia are significantly higher in NMOSD compared to the general population and in related conditions such as multiple sclerosis (MS). In contrast to MS, NMOSD disease activity does not subside during pregnancy. Also, relapse risk substantially rises above pre-pregnancy rates in the early postpartum period. In view of the evolving landscape of NMOSD, we provide a contemporary update of the impacts of pregnancy in NMOSD.

Therapeutic changes of systemic lupus erythematosus (SLE) patients in pregnancy and feto-maternal outcomes: a retrospective cohort study

OBJECTIVES

Patients with systemic lupus erythematosus (SLE) frequently show non-compliance with their medication. We evaluated the compliance of patients with SLE in Jordan with their medication and the relationships with fetal and maternal outcomes.

METHODS

We performed a retrospective cohort study of patients with SLE who had no co-morbidities or antiphospholipid syndrome; and were taking only prednisolone, hydroxychloroquine, and/or antiplatelet and anticoagulant medication.

RESULTS

We studied 173 pregnancies. Prednisolone was administered around pregnancy in 50 (28.9%) of these. The compliance with hydroxychloroquine, prednisolone, and anticoagulant and antiplatelet medication was 87.5%, 91.4%, and 97.3%, respectively. Non-compliance with anticoagulant/antiplatelet therapy was significantly associated with pregnancy-related complications. No complications developed in participants who were non-compliant with prednisolone therapy. The mean pre-pregnancy Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) for the pregnancies was 3.7, indicating low disease activity. Pregnancies with high pre-pregnancy SLEDAI scores tended to be more likely to have preterm deliveries, intrauterine growth restriction, and stillbirth. Postpartum relapse tended to be associated with higher pre-pregnancy SLEDAI.

CONCLUSIONS

In patients with pre-conceptional low SLE activity, changes in therapeutic compliance during pregnancy are not associated with adverse outcomes. In addition, post-partum relapse is not associated with pre-pregnancy SLEDAI score in therapeutically compliant patients.

A decreased number of circulating regulatory T cells is associated with adverse pregnancy outcomes in patients with systemic lupus erythematosus

OBJECTIVE

As an autoimmune disease affecting women of reproductive age, systemic lupus erythematosus (SLE) is linked to adverse fetal and maternal outcomes. However, the status of peripheral lymphocytes in SLE patients with different pregnancy outcomes is unclear. This retrospective cross-sectional study explored the relationship between lymphocyte subpopulations and pregnancy outcomes in married SLE female patients.

METHODS

The absolute numbers of peripheral T, helper T (Th)1, Th2, Th17, regulatory T (Treg), B, and natural killer (NK) cell subpopulations from 585 female SLE patients and 91 female healthy controls (HCs) were assessed. We compared the lymphocyte subpopulations in SLE patients with HCs and analyzed the absolute number and ratio of Treg cells according to pregnancy outcome in SLE patients.

RESULTS

SLE patients had decreased numbers of T, B, NK, Th1, Th2, Th17, and Treg cells and an imbalance in pro- and anti-inflammatory cells (p < .05), as well as adverse pregnancy outcomes. In abortion patients, the number of Treg cells (p = .008) decreased, leading to an imbalance in effector T and Treg cells. The ratio of Treg cells was higher in SLE patients with nulliparity than in those with one or two parities.

CONCLUSIONS

The absolute numbers of lymphocyte subpopulations in SLE patients decreased, which was associated with abortion and parity (p < .05). These results suggest that a loss of immune tolerance mediated by Tregs triggers pregnancy loss.

Hollow Cobalt Oxide/Carbon Hybrids Aid Metabolic Encoding for Active Systemic Lupus Erythematosus during Pregnancy

A noninvasive, easy operation, and accurate diagnostic protocol is highly demanded to assess systemic lupus erythematosus (SLE) activity during pregnancy, promising real-time activity monitoring during the whole gestational period to reduce adverse pregnancy outcomes. Here, machine learning of serum metabolic fingerprints (SMFs) is developed to assess the SLE activity for pregnant women. The SMFs are directly extracted through a hollow-cobalt oxide/carbon (Co₃ O₄ /C)-composite-assisted laser desorption/ionization mass spectrometer (LDI MS) platform. The Co₃ O₄ /C composite owns enhanced light absorption, size-selective trapping, and better charge-hole separation, enabling improved ionization efficiency and selectivity for LDI MS detection toward small molecules. Metabolic fingerprints are collected from ≈0.1 µL serum within 1 s without enrichment and encoded by the optimized elastic net algorithm. The averaged area under the curve (AUC) value in the differentiation of active SLE from inactive SLE and healthy controls reaches 0.985 and 0.990, respectively. Further, a simplified panel based on four identified metabolites is built to distinguish SLE flares in pregnant women with the highest AUC value of 0.875 for the blind test. This work sets an accurate and practical protocol for SLE activity assessment during pregnancy, promoting precision diagnosis of disease status transitions in clinics.

Biomarkers of pneumonia disease in under five children in "grill culture"

OBJECTIVE

Based on data WHO in 2018, almost 802,200 cases of pneumonia occur in children. Indonesia data on Riskesdas in 2018, the increase in pneumonia with the prevalence of pneumonia based on the age group 1-4 years was 5.0. This study aims to obtain more information about biomarkers of the clinical assessment on patient cases and prevention management and then whether postpartum culture contributed to the increase in pneumonia.

METHODS

The method used is a Literature review. Search for scientific articles collected through Scopus indexed journals through Science Direct, Pubmed, Elsevier, MDPI, WHO, Riskesdas, Google Scholar.

RESULT

From the literature articles we read, it shows that the incidence of pneumonia increases from year to year and is the leading cause of death. So it needs prevention from use biomarkers as markers and examined the association of Grill Culture with pneumonia in children under five.

CONCLUSION

The results of the biomarker examination are a marker of the case and prevention management will be carried out using existing cultural approaches.

Impact of Systemic Lupus Erythematosus on Pregnancy: Analysis of a Large 10-Year Longitudinal Mexican Cohort

BACKGROUND

Pregnancy in patients with systemic lupus erythematosus is considered a high risk one since it is associated with a higher rate of maternal-fetal complications compared with the pregnancies in healthy women.

OBJECTIVES

The aim of this study was to describe the maternal-fetal outcomes in a cohort of Mexican patients with systemic lupus erythematosus and to identify risk factors associated with adverse maternal and fetal outcomes.

PATIENTS AND METHODS

A cohort of pregnant lupus patients was analyzed. Maternal-fetal complications were described, and clinical, biochemical, and immunological variables associated with obstetric adverse outcomes were studied. Descriptive statistics, comparison of variables using appropriate tests, and finally logistic regression analysis were performed to identify potential risk factors for adverse maternal and fetal outcomes.

RESULTS

A total of 351 pregnancies were included in a 10-year period. The most frequently observed maternal adverse outcomes were lupus flare (35%) and preeclampsia (14.5%). Active lupus before pregnancy (hazards ratio [HR], 3.7; 95% confidence interval [CI], 1.1-12.5; p = 0.003) was a predictor for these complications, whereas the use of antimalarial drugs (HR, 0.4; 95% CI, 0.2-0.7; p = 0.007) was a protective factor. The most frequent fetal adverse outcomes were preterm birth (38.1%), miscarriages (10%), and low birth weight babies (28%), and very low birth weight newborns (11%). Proteinuria in early pregnancy (HR, 7.1; 95% CI, 1.01-50.3; p = 0.04) and preeclampsia (HR, 9.3; 95% CI, 1.7-49.7; p = 0.009) were risk factors associated with these complications.

CONCLUSIONS

Variables related to systemic lupus erythematosus activity predict an adverse maternal outcome, whereas proteinuria in early pregnancy and preeclampsia are associated with an adverse fetal outcome.

Outcomes of pregnancy and associated factors in sub-Saharan African women with systemic lupus erythematosus: a scoping review

Objective

To scope and summarise available literature on the outcomes of pregnancy and associated factors in sub-Saharan African women with SLE.

Methods

Electronic databases and reference lists of retrieved articles were searched to identify relevant studies published from 1 January 2000 to 28 October 2019. Data were combined through narrative synthesis.

Results

We included four studies retrospectively reporting a total of 137 pregnancies in 102 women over a 26-year period. Mean age at conception ranged from 27.2 to 39.9 years. Kidney damage, the predominant organ manifestation before conception, was reported in 43 (42.2%) patients. Ninety-seven (70.8%) pregnancies resulted in 98 live births. SLE flares occurred in 44 (32.2%) pregnancies, mainly skin (20.4%) and renal (18.2%) flares. Major adverse pregnancy outcomes (APOs) were preterm birth 38.8%, low birth weight 29.8%, pregnancy loss 29.2% and pre-eclampsia 24.8%. The main factors associated with APOs were nephritis and SLE flares.

Conclusion

Over two-thirds of pregnancies resulted in live birth in this cohort of sub-Saharan African women with SLE. The main APOs and associated factors described in other parts of the world are also seen in this region, but with high rates of APOs. A large prospective multinational study is warranted for more compelling evidence.
