RESUMO

BACKGROUND: Complement levels have been proposed as candidate biomarkers of disease activity and obstetric risk in systemic lupus erythematosus (SLE) pregnancies, but their reliability has been questioned due to the physiologic fluctuations of complement during gestation. Thus, this network meta-analysis aimed at assessing the clinical significance of complement fluctuations in lupus pregnant women. METHODS: Corresponding authors of 19 studies meeting inclusion criteria were invited to contribute with additional data including C3 and C4 levels [before pregnancy, at conception, in every trimester (T) and 3 months after delivery]; data were pooled together in a network meta-analysis. RESULTS: A total of 532 lupus women from four studies were included in the analysis. In SLE women, C3 and C4 increased progressively during gestation: levels remained stable during T1 and peaked in T2 to decrease in T3. Patients with previous lupus nephritis (LN) and those who experienced flares during pregnancy had significantly lower mean levels of C3 and C4 at all timepoints. The lowest levels of complement were observed, particularly during T1, in patients with LN and gestational flare. Both reduction and the lack of increase of C3 and C4 levels at T1 versus conception were associated with gestational flares, particularly in LN patients. Pregnancies with flare had a statistically significant higher rate of maternal and fetal complications(60% versus 50.3%; p = 0.03). CONCLUSIONS: Low complement levels, particularly in T1, were associated with a higher frequency of gestational flare. Either reduction or smaller increase of C3 and/or C4 levels, even within normal range, might predict flares especially in early gestation.

RESUMO

OBJECTIVE: The aim of this study was to analyze the occurrence and risk factors associated with infections during pregnancy in patients with systemic lupus erythematosus. METHODS: This is a retrospective cohort study using the data of pregnant women who were followed up between 2011 and 2018 at a university hospital. RESULTS: The data of 221 pregnant women with systemic lupus erythematosus were analyzed. The incidence of infections was 22.6% (50/221), with the urinary tract being the most frequent site of infection (32/221, 14.5%) followed by the respiratory tract (15/221, 6.8%). The bivariate analysis showed that active disease, hematological systemic lupus erythematosus, reduced complement, and use of prednisone ≥5 and ≥10 mg increased the chance of infection during early pregnancy (p=0.05, p=0.04, p=0.003, p=0.008, and p=0.02, respectively), while disease activity and anti-DNA positivity increased it at the end of pregnancy (p=0.03 and p=0.04, respectively). Prednisone at a dose ≥5 mg increased the chance of infection in the beginning (p=0.01) and at the end of pregnancy (p=0.008). Multivariate analysis showed that increasing the dose of prednisone from 5 to 10 mg tripled the chance of developing infections in pregnant women with lupus (p=0.02). CONCLUSION: The study showed an increased chance of infections in pregnant women with systemic lupus erythematosus and it was associated with the use of prednisone.

RESUMO

Acute vulvar ulcer (Lipschütz's ulcer) is a rare lesion with local hyperimmunoreactivity triggered by infection, which is characterized by acute, painful, and necrotic ulcerations. This condition is usually found in non-sexually active adolescents, and it resolves spontaneously. We report a case of a 35-year-old woman who was diagnosed with COVID-19 who did not have severe symptoms, but had high levels of D-dimer for 9 days. The COVID-19 diagnosis was followed by the appearance of an acute, necrotic, extremely painful vulvar ulcer, although symptoms caused by COVID-19 had improved. We emphasize the importance of the differential diagnosis to exclude diseases such as Behçet's syndrome, Sexually Transmitted Infections, as well as the presence of viruses that generally trigger Lipschütz's ulcer, such as Epstein-Barr virus and cytomegalovirus. No treatment is usually necessary, however, in the present report due to the pain experienced by the patient, we successfully used oral prednisone.

RESUMO

OBJECTIVE: The objective of this study was to evaluate the potential impact of irreversible damage accrual in women with systemic lupus erythematosus (SLE) and adverse maternal and/or fetal/neonatal outcomes. METHODS: Retrospective cohort study with SLE pregnant patients was carried out from January 2011 to January 2020 at the Hospital University Pedro Ernesto (HUPE) of the State University of Rio de Janeiro, Brazil. Irreversible damage was defined according to SLICC/ACR damage index (SDI). The association of SDI on pregnancy outcomes was established by univariate and multivariate regression models and included demographic and clinical variables. RESULTS: This study included data from 260 patients in their first pregnancies after SLE diagnosis, with a quarter of them (67/260) scoring one or more points on SDI at the beginning of prenatal care. These patients presented more frequently adverse maternal events, namely, disease activity during pregnancy (p = 0.004) and puerperium (p = 0.001), active lupus nephritis (p = 0.04), and hospitalizations (p = 0.004), than those with no SDI score. Similarly, the risks of adverse fetal and neonatal outcomes were also higher among the patients with SDI ≥ 1 (59.7% vs 38.3% p = 0.001) even after controlling data for disease activity (SLEPDAI > 4). Patients with SDI ≥ 1 presented more frequently preterm deliveries (46.3% vs 31.6%; p = 0.01), small for gestational age infants (28.3% vs 18.1%; p = 0.04), and neonatal intensive care unit admission (26.9% vs 1.5%; p < 0.001). The multivariate analyses showed that SDI ≥ 1 is an independent risk factor for hospitalization due to obstetric complications (p = 0.0008) and preterm delivery (p = 0.009). CONCLUSION: Pregnant SLE patients who present irreversible damage accrual may have higher risk of maternal and fetal adverse outcomes, independently of disease activity. These results should be validated in further prospective studies.

RESUMO

This article describes three complicated cases in rheumatology and pregnancy. The first case elucidates the challenges in treating SLE in conjunction with pulmonary arterial hypertension, while the second case features an SLE-affected pregnancy with development of portal hypertension secondary to portal vein thrombosis related to APS. The third case is a pregnant woman with stable SLE who developed thrombotic microangiopathy caused by atypical haemolytic uraemic syndrome, and failed to improve despite multiple measures including biopsy and elective preterm delivery. There are grave and unique challenges for women with autoimmune disease, but adverse outcomes can sometimes be avoided with careful and multidisciplinary medical management. Pre-conception counselling with regard to medications and disease treatment should also include discussion of the advisability of pregnancy, which may be difficult for a patient, but present the best course for optimizing health outcomes.

RESUMO

Patients with Systemic Lupus Erythematosus (SLE) are at increased risk for infections. Vaccination is a powerful tool to prevent infections, even in immunocompromised patients. Most non-live vaccines are immunogenic and safe in patients with SLE, even if antibody titres are frequently lower than those of healthy controls. Human papillomavirus (HPV) infections are more prevalent in SLE patients when compared to the healthy population. Low-risk types of this virus cause anogenital warts, while high risk types are strongly related to pre-malignant cervical abnormalities and cervical cancer. HPV vaccines have been developed to prevent these conditions. Although little is known about HPV vaccination in SLE, few studies in patients with autoimmune rheumatic diseases (AIRDs) have shown that HPV vaccines are safe, and capable to induce an immunogenic response in this group of patients. To date, available data suggest that HPV vaccines can be given safely to SLE patients. Given the increased incidence of cervical abnormalities due to HPV in SLE patients, this vaccination should be encouraged.
