RESUMEN
AIM: The aim of the study was to evaluate the association between SARS-CoV-2 infection and serum hepatic biomarker levels among women with obstetric cholestasis. METHODS: In this prospective study, we recruited all pregnant women admitted in our hospital with obstetric cholestasis. Among those with a concurrent SARS-CoV-2 infection, we evaluated the following serum hepatic biomarkers: aspartate aminotransferase (AST), alanine aminotransferase (ALT), and biliar acids (BA). RESULTS: Among the 88 women enrolled in the study, 20 presented with a SARS-CoV-2 infection while 68 were negative. SARS-CoV-2 infected women were younger (mean age 30.5 ± 5.7 vs. 34.3 ± 5.4; p < 0.01) and in a greater percentage of non-Caucasian ethnicity when compared to noninfected women (60.0% vs. 17.6%; p < 0.01). Regarding levels of hepatic biomarkers, they showed higher levels of AST (111.5 ± 134.1 vs. 37.3 ± 43.4 UI/L; p = 0.02), ALT (132.2 ± 115.7 vs. 50.5 ± 73.173.1 UI/L; p < 0.01), and BA (41.4 ± 46.8 vs. 18.4 ± 13.4 µmol/L; p = 0.04) compared to noninfected patients. No significant differences in maternal or fetal outcomes were found between infected and noninfected women. CONCLUSION: SARS-CoV-2 infection was associated with higher levels of liver enzymes in patients with obstetric cholestasis. This could be the result of a possible hepatic involvement in patients with SARS-CoV-2 infection.

INTRODUCTION: The aim of the present study was to evaluate fetal umbilical artery (UA) and middle cerebral artery (MCA) blood flow in patients with gestational diabetes (GD), in order to determine whether minimal anomalies of glucose metabolism may influence fetal placental function. METHODS: UA and MCA flows were prospectively measured by transabdominal ultrasound in singleton pregnancies between 34 and 37 weeks of gestation. RESULTS: The study included 35 women with GD and 217 nondiabetic patients. Middle cerebral pulsatility index (PI) was significantly higher in the GD group (mean MCA-PI = 1.82 ± 0.27 vs. 1.71 ± 0.26; p < 0.02). Likewise, MCA peak systolic velocity (MCA-PSV) was higher in the GD group compared to the non-GD group, though the difference was not significant (mean of MCA-PSV = 47.14 ± 8.45 vs. 47.09 ± 11.21; p = 0.98). UA-PI resulted higher in the non-GD group without significant differences (mean of UA-PI = 0.88 ± 0.14 vs. 0.86 ± 0.15; p = 0.32). CONCLUSIONS: Our study shows that even in cases of minimal metabolic derangements, GD is characterized by a significant variation in fetal Doppler velocimetry, particularly in the brain.

INTRODUCTION: We investigated association between sociodemographic characteristics and COVID-19 disease among pregnant women admitted to our unit, the largest high-risk maternity unit in the Milan metropolitan area. METHODS: Between March 1, 2020 and April 30, 2020, 896 pregnant women were admitted to our Institution and tested for COVID-19. We collected information regarding their sociodemographic characteristics. Additional information on geographical area of residence, number of family members, number of family members tested positive for COVID-19, and clinical data was collected for women tested positive for COVID-19. Odds ratios (ORs) and 95% confidence intervals (CIs) for the risk of developing COVID-19 according to sociodemographic characteristics were estimated by unconditional logistic regression models. RESULTS: Among the 896 women enrolled, 50 resulted positive for COVID-19. Pregnant women aged ≥35 years had a significantly lower risk of developing the infection (crude OR = 0.29; 95% CI:0.16-0.55). Conversely, foreign women (crude OR = 3.32; 95% CI:1.89-5.81), unemployed women (crude OR = 3.09; 95% CI: 1.77-5.40), and women with an unemployed partner (crude OR = 3.16; 95% CI: 1.48-6.79) showed a significantly higher risk of infection. Ethnicity was positively associated with the risk of developing COVID-19 (mutually adjusted OR = 2.15; 95% CI:1.12-4.11) in the multivariate analysis. Foreign women with COVID-19 were more likely to have a lower education level (p < 0.01), to be unemployed (p < 0.01), and to live in larger families (p < 0.01) compared to Italian pregnant women. CONCLUSIONS: The socioeconomic conditions described are characteristic of immigration patterns in our metropolitan area. These factors may increase the risk of viral transmission, reducing the effectiveness of lockdown and social distancing.

OBJECTIVES: To investigate pregnancy outcomes in women with autoimmune rheumatic diseases (ARD) in the Italian prospective cohort study P-RHEUM.it. METHODS: Pregnant women with different ARD were enrolled for up to 20 gestational weeks in 29 Rheumatology Centres for 5 years (2018-2023). Maternal and infant information were collected in a web-based database. RESULTS: We analysed 866 pregnancies in 851 patients (systemic lupus erythematosus was the most represented disease, 19.6%). Maternal disease flares were observed in 135 (15.6%) pregnancies. 53 (6.1%) pregnancies were induced by assisted reproduction techniques, 61 (7%) ended in miscarriage and 11 (1.3%) underwent elective termination. Obstetrical complications occurred in 261 (30.1%) pregnancies, including 2.3% pre-eclampsia. Two cases of congenital heart block were observed out of 157 pregnancies (1.3%) with anti-Ro/SSA. Regarding treatments, 244 (28.2%) pregnancies were treated with glucocorticoids, 388 (44.8%) with hydroxychloroquine, 85 (9.8%) with conventional synthetic disease-modifying anti-rheumatic drugs and 122 (14.1%) with biological disease-modifying anti-rheumatic drugs. Live births were 794 (91.7%), mostly at term (84.9%); four perinatal deaths (0.5%) occurred. Among 790 newborns, 31 (3.9%) were small-for-gestational-age and 169 (21.4%) had perinatal complications. Exclusive maternal breast feeding was received by 404 (46.7%) neonates. The Edinburgh Postnatal Depression Scale was compiled by 414 women (52.4%); 89 (21.5%) scored positive for emotional distress. CONCLUSIONS: Multiple factors including preconception counselling and treat-to-target with pregnancy-compatible medications may have contributed to mitigate disease-related risk factors, yielding limited disease flares, good pregnancy outcomes and frequency of complications which were similar to the Italian general obstetric population. Disease-specific issues need to be further addressed to plan preventative measures.

OBJECTIVES: To analyze soluble Fms-like tyrosine Kinase 1 (sFlt-1) and Placental Growth Factor (PlGF) ratio concentrations in COVID-19 pregnant patients with and without Hypertensive Disorders of Pregnancy (HDP), compared with non COVID-19 pregnant patients with HDP and a control group. STUDY DESIGN: We recruited and obtained a complete follow-up of 19 COVID-19 pregnant patients with HDP and of 24 COVID-19 normotensive pregnant patients. Demographic, clinical and sFlt-1/PlGF ratio findings were compared with a group of 185 non COVID-19 pregnant patients with HDP and 41 non COVID normotensive patients. Findings were based on univariate analysis and on a multivariate adjusted model, and a case by case analysis of COVID-19 pregnant patients with an abnormal sFlt-1/PlGF ratio > 38 at recruitment. MAIN OUTCOME MEASURES: sFlt-1/PlGF ratio. RESULTS: We confirmed a significant higher prevalence of HDP in women affected by COVID-19 compared to control population. sFlt-1/PlGF ratio was found high in HDP patients, with and without of Sars-Cov2 infection. COVID-19 patients with worse evolution of the disease showed greater rates of obesity and other comorbidities. sFlt/PlGF ratio proved not to be helpful in the differential diagnosis of the severity of this infection. CONCLUSIONS: COVID-19 pregnant patients showed a higher prevalence of HDP compared to non COVID-19 controls, as well as higher comorbidity rates. In spite of the possible common endothelial target and damage, between Sars-Cov-2 infection and HDP, the sFlt1/PlGF ratio did not correlate with the severity of this syndrome.

The efficacy of low molecular weight heparin (LMWH) is well-established in patients with obstetric antiphospholipid syndrome (O-APS). Their role in women with unexplained recurrent pregnancy loss (U-RPL) and late obstetrical complications (intrauterine growth restriction, IUGR and preeclampsia) is controversial. Here we compared rates of miscarriage and late obstetrical complications in RPL patients diagnosed with O-APS (n = 57) or hereditary thrombophilia (n = 25) (both assuming LMWH from the beginning of pregnancy) and in patients with a history of U-RPL (n = 118), assuming or not LMWH, followed at the 'Pregnancy at risk' and 'Recurrent pregnancy loss' outpatient clinics at the San Raffaele Hospital from April 2010 to April 2020. Patients with systemic autoimmune diseases other than primary O-APS were excluded. We tested for bivariate or multivariate associations among adverse pregnancy outcomes, the presence of thrombophilia and LMWH use by using chi-square test, Anova, propensity score adjusted univariate logistic regression and multivariate analysis as appropriate. U-RPL patients assuming LMWH from the beginning of pregnancy (group A) had a significantly lower rate of miscarriage compared to U-RPL patients who were not treated with LMWH (group B) (13 % vs. 41 % respectively, p 0.001) and similar pregnancy rates compared to both O-APS patients with a history of RPL taking LMWH (group C, 18 %) and RPL patients with thrombophilia and treated with LMWH (group D, 16 %). Our data highlight a protective effect of LMWH on miscarriage in patients with a history of U-RPL. In these patients, LMWH seems as effective as in O-APS and hereditary thrombophilia in reducing RPL.

OBJECTIVE: It is still a matter of debate whether low-dose acetylsalicylic acid (LDASA) should be prescribed to all patients with SLE during pregnancy. This study aimed at investigating the impact of LDASA on pregnancy outcomes in patients with SLE without history of renal involvement and without antiphospholipid antibodies (aPL). METHODS: This is a retrospective analysis of prospectively monitored pregnancies at seven rheumatology centres. Previous/current renal involvement and aPL positivity were the exclusion criteria. Adverse pregnancy outcome (APO) is the composite outcome of the study and included proteinuric pre-eclampsia, preterm delivery <37 weeks, small-for-gestational age infant, low birth weight <2500 g, intrauterine growth restriction and intrauterine fetal death after 12 weeks of gestation of a morphologically normal fetus. RESULTS: 216 pregnancies in 187 patients were included; 82 pregnancies (38.0%) were exposed to LDASA treatment. No differences in terms of age at conception, disease duration, clinical manifestations, comorbidities and disease flare during pregnancy were observed between patients taking LDASA and those who did not take LDASA during pregnancy. APO was observed in 65 cases (30.1%), including 13 cases (6.1%) of pre-eclampsia. The incidence of all complications was similar in the two groups. However, it is interesting to note that pre-eclampsia had lower frequency in patients taking LDASA versus those not taking LDASA (2.4% vs 8.3%, p=0.14). CONCLUSIONS: In pregnant patients with SLE without renal involvement and were aPL-negative, there is a low risk of severe obstetric complications, such as early pre-eclampsia. LDASA treatment does not provide a statistically significant advantage over these complications. However, a careful individual risk-benefit balance is warranted.

Systemic lupus erythematosus (SLE) preferentially affects women of childbearing age. Miscarriages or fetal death, intrauterine growth restriction (IUGR), preterm delivery, preeclampsia and disease flares complicate pregnancy in SLE patients. Treatment is challenging due to the need to prevent disease exacerbations and limit obstetrical complications, while showing an acceptable safety profile for both the mother and the fetus. We collected data from 74 pregnancies in 53 SLE patients prospectively followed in a dedicated 'Pregnancy at risk' outpatient clinic from 2003 to 2019. Out of 74, 45 pregnancies patients were treated with hydroxychloroquine (HCQ). Mothers under HCQ therapy (HCQ+ patients) and those who did not receive HCQ (HCQ-) were homogeneous in terms of age and comorbidities. Disease activity prior to conception was slightly higher in HCQ+ patients. No significant difference was observed in terms of obstetrical history. In patients achieving a viable pregnancy, the rate of IUGR (4/39, 10% in HCQ+ vs 8/25, 32%, in HCQ- patients, p < .05) was significantly lower in HCQ+ patients. Conversely, HCQ+ patients displayed a significantly longer time to delivery (37.8 ± 1.72 vs. 36.3 ± 4.11 in HCQ- patients, p < .05). HCQ is safe in pregnant patients with SLE and protects against obstetrical complications.

The effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the pathophysiology of the placenta and its impact on pregnancy outcome has not yet been fully elucidated. Here, we present a comprehensive clinical, morphological, and molecular analysis of placental tissues from pregnant women with and without SARS-CoV-2 infection. SARS-CoV-2 could be detected in half of placental tissues from SARS-CoV-2-positive women. The presence of the virus was not associated with any distinctive pathological, maternal, or neonatal outcome features. SARS-CoV-2 tissue load was low in all but one patient who exhibited severe placental damage leading to neonatal neurological manifestations. The placental transcriptional response induced by high viral load of SARS-CoV-2 showed an immunopathology phenotype similar to autopsy lung tissues from patients with severe coronavirus disease 2019. This finding contrasted with the lack of inflammatory response in placental tissues from SARS-CoV-2-positive women with low viral tissue load and from SARS-CoV-2-negative women. Importantly, no evidence of vertical transmission of SARS-CoV-2 was found in any newborns, suggesting that the placenta may be an effective maternal-neonatal barrier against the virus even in the presence of severe infection. Our observations suggest that severe placental damage induced by the virus may be detrimental for the neonate independently of vertical transmission.

Background: Systemic lupus erythematosus (SLE) is associated with a constellation of complications affecting multiple organs, including neuropsychiatric manifestations (NPSLE) and ischaemic events, leading to increased long-term morbidity. Antiphospholipid antibodies (aPL) are a major determinant of vascular inflammation and thromboembolic risk. The diagnostic role of anti-phosphatidylserine/prothrombin (aPS/PT) antibodies in this setting is incompletely defined.Aim: To verify whether aPS/PT add to diagnostics and disease stratification in patients with SLE with or without other aPL.Methods: 131 consecutive patients were studied, including 20 patients with SLE and secondary antiphospholipid syndrome (APS). aPS/PT IgG and IgM were assessed through ELISA and patients were stratified based on the presence of other aPL, on their clinical and laboratory features at time of blood sampling and on their clinical history. Synthetic indices of disease activity, chronic damage and cardiovascular risk were calculated at time of venipuncture.Results: Fifty-one (38.9%) patients with SLE had aPS/PT and 15 (11.5%) patients had aPS/PT as the only aPL (aPS/PT-only). aPS/PT-only patients had a significantly higher prevalence of NPSLE than quadruple aPL-negative patients (p = .007). Patients with aPS/PT were more likely to have a history of ischaemia, thrombocytopenia and Libman-Sacks' endocarditis. The presence of aPS/PT also associated with previous accrual of at least one damage item (p = .043), but had limited predictive values for damage progression in the short term.Conclusion: aPS/PT antibodies provide non-redundant information that could contribute to risk assessment and stratification of patients with SLE.

RATIONALE: Hypercoagulability and pregnancy morbidity are hallmarks of the antiphospholipid syndrome (APS). Catastrophic antiphospholipid syndrome (CAPS) is a potentially life-threatening omplication of APS, with widespread acute thrombotic microangiopathy (TMA) that can be precipitated by pregnancy and delivery and result in multiorgan damage. Unrestrained activation of the complement cascade is involved, favoring endothelial activation, tissue factor expression by leukocytes, and platelet aggregation. The complement block, which interrupts this amplification cycle, could prevent CAPS in patients with early TMA who face precipitating events. PATIENT CONCERNS: We present a nulliparous pregnant woman with APS at the 30 week of gestation who has developed thrombocytopenia, intravascular hemolysis, elevated creatinine, proteinuria, and hematuria. DIAGNOSES: These featurs were compatible with the diagnosis of CAPS. Consensually, serum C3 protein levels were rapidly decreasing, reflecting complement consumption. INTERVENTIONS: She was treated with eculizumab, a humanized monoclonal antibody against C5 that prevents the formation of the complement membrane attack complex. OUTCOMES: Laboratory parameters improved and the patient did not develop thrombosis or detectable organ/tissue damage. The patient safely delivered by cesarean section at week 32 of gestation a healthy 1640âg male infant. After 5 days, she received additional eculizumab, with complete resolution of the clinical condition. Low complement activity was detectable in the infant blood for a week after delivery. No infectious complication occurred. LESSONS: Inhibition of the terminal complement activation is safe and might be effective in patients with APS developing early TMA, enabling safe delivery and preventing thrombotic events both in the mother and in the newborn.
