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.

Use of antimalarial drugs is associated with a lower risk of preeclampsia in lupus pregnancy: A prospective cohort study.

Introduction: Several factors have been associated with the development of preeclampsia in women with systemic lupus erythematosus (SLE).

Objective: To identify risk factors associated with preeclampsia in patients with SLE and its impact on fetal outcomes.

Patients And Methods: We studied a prospective cohort of pregnancies in women with SLE from January 2009 to December 2018.

Clinical practice guidelines for the treatment of systemic lupus erythematosus by the Mexican College of Rheumatology.

There are national and international clinical practice guidelines for systemic lupus erythematosus treatment. Nonetheless, most of them are not designed for the Mexican population or are devoted only to the treatment of certain disease manifestations, like lupus nephritis, or are designed for some physiological state like pregnancy. The Mexican College of Rheumatology aimed to create clinical practice guidelines that included the majority of the manifestations of systemic lupus erythematosus, and also incorporated guidelines in controversial situations like vaccination and the perioperative period.

Detection of autoantibodies to DSF70/LEDGFp75 in Mexican Hispanics using multiple complementary assay platforms.

Purpose: Antinuclear autoantibodies (ANA) targeting the dense fine speckled antigen DFS70, also known as lens epithelium-derived growth factor p75 (LEDGF/p75), are attracting attention due to their low frequency in systemic rheumatic diseases but increased frequency in clinical laboratory referrals and healthy individuals (HI). These ANA specifically recognize the stress protein DFS70/LEDGFp75, implicated in cancer, HIV-AIDS, and inflammation. While their frequency has been investigated in various ethnic populations, there is little information on their frequency among Hispanics/Latinos.

Pregnancy outcomes in women with childhood-onset and adult-onset systemic lupus erythematosus: a comparative study.

To compare the maternal and fetal outcomes between childhood-onset and adult-onset systemic lupus erythematosus (SLE), we reviewed the medical records of SLE pregnant women treated from January 2005 to August 2013. For comparison, patients were allocated to one of the two groups, those pregnant patients with SLE onset before 18 years of age (childhood-onset) and ≥18 years (adult-onset). The patients were evaluated at least once in each trimester and postpartum.

Azathioprine during pregnancy in systemic lupus erythematosus patients is not associated with poor fetal outcome.

The objective of this study was to evaluate the risk of adverse fetal outcome in systemic lupus erythematosus (SLE) women exposed to azathioprine during pregnancy. We reviewed the medical records of SLE pregnant women followed from January 2005 to April 2013. The patients were evaluated at least once in each trimester and postpartum.

Prognostic factors for treatment response in patients with lupus nephritis.

Objective: To identify prognostic factors associated with response to induction therapy in lupus nephritis (LN) according to the stage of treatment.

Material And Methods: We analyzed a retrospective cohort of patients of systemic lupus erythematosus (SLE) with biopsy-proven LN from January 2001 to December 2008. LN was classified according to WHO.

Systemic autoimmune diseases in patients with hepatitis C virus infection: characterization of 1020 cases (The HISPAMEC Registry).

Objective: To describe the clinical and immunologic characteristics of a large series of patients with systemic autoimmune diseases (SAD) associated with chronic hepatitis C virus (HCV) infection.

Methods: The HISPAMEC Registry is a multicenter international study group dedicated to collecting data on patients diagnosed with SAD with serological evidence of chronic HCV infection. The information sources are cases reported by physicians of the HISPAMEC Study Group and periodic surveillance of reported cases by a Medline search updated up to December 31, 2007.

Effect of prolactin on lymphocyte activation from systemic lupus erythematosus patients.

The aim was to explore the role of prolactin (PRL) in the lymphocyte activation process in systemic lupus erythematosus (SLE) patients in an in vitro model. Peripheral blood mononuclear cells (PBMCs) were isolated from SLE patients and healthy individuals. The mRNA for PRL and its receptor obtained by standard techniques, with an appropriate primer, were subjected to polymerase chain reaction (PCR) and visualized.

[Influence of non-complicated urinary tract infection on renal relapses in proliferative lupus nephritis].

Objective: In patients with proliferative lupus nephritis treated with IV cyclophosphamide, analyze urinary tract infection (UTI) as a cause of treatment delay and renal relapses, compared with lupus nephritis patients without infection.

Patients And Methods: We studied SLE patients (ACR criteria) with renal biopsy showing nephritis class IV. All patients received monthly intravenous cyclophosphamide (CYC) treatment during 6 months.
