 Type I interferons (IFN) are primarily regarded as an inhibitor of viral replication. However, type I IFN, mainly IFNα, has a major role in activation of both the innate and adaptive immune systems. Systemic lupus erythematosus (SLE) is a chronic, multi-systemic, inflammatory autoimmune disease with undefined etiology. SLE is characterized by dysregulation of both the innate and the adaptive immune systems. An increased expression of type I IFN-regulated genes, termed IFN signature, has been reported in patients with SLE. We review here the role of IFNα in the pathogenesis and course of SLE and the possible role of IFNα inhibition as a novel treatment for lupus patients.

Background: Antiphospholipid syndrome (APS, also known as Hughes syndrome) may manifest itself as a primary or secondary disease, most commonly with systemic lupus erythemathosus (SLE) and various cardiac manifestations. 

Objectives: To report the first results from the Serbian National Cohort study, which was started in January 2000.

Methods: Our study included 374 patients: 260 primary APS patients and 114 SLE patients with secondary APS. Antiphospholipid antibody (aPL) analysis included detection of anticardiolipin antibodies (aCL) (immunoglobulin G and M), ß2-glycoprotein 1, and lupus anticoagulant. Echocardiography was performed in all patients, and data on myocardial infarction, unstable angina, chronic cardiomyopathy and acute heart failure were collected.

Results: There were 30.7% secondary APS patients and 9.2% primary APS patients with pseudo-infective endocarditis (P = 0.0001). Cardiac manifestations were observed in 28.7% of patients who had more than one type of antibody (category I), in 24.1% with category IIa, in 23.1% with category IIb, and in 27.8% with category IIc (P = 0.78). Age was confirmed as a significant factor for cardiac manifestations in APS patients (52.3 and 43.3 years, respectively, P = 0.001). aCL IgG and IgM positivity was related to valvular changes in all APS patients and high levels of those antibodies increased the risk of these manifestations.

Conclusions: Patients with secondary APS had a higher prevalence of valvular lesions, and some aPL types and high levels of aPL were risk factors for specific cardiac manifestations in APS patients.

Erythema nodosum and pyoderma gangrenosum are common skin manifestations in inflammatory bowel diseases. Curiously, these two cutaneous features have seldom been reported to occur simultaneously.  We present three patients affected with inflammatory bowel disease, with concomitant erythema nodosum and pyoderma gangrenosum.

 Systemic lupus erythematosus (SLE) is a complex autoimmune disorder involving multiple organs. One of the main sites of SLE morbidity is the central nervous system (CNS), specifically the brain. In this article we review several imaging modalities used for CNS examination in SLE patients. These modalities are categorized as morphological and functional. Special attention is given to magnetic resonance imaging (MRI) and its specific sequences such as diffusion-weighted imaging (DWI), diffuse tensor imaging (DTI) and magnetic resonance spectroscopy (MRS). These modalities allow us to better understand CNS involvement in SLE patients, its pathophysiology and consequences.

Current treatments for systemic lupus erythematosus (SLE) are effective in reducing morbidity and mortality but are not specific and have severe adverse effects. Based on understanding of the different dysregulated immunological pathways involved in SLE pathogenesis, specific targeted therapies were developed. This review presents the current and the near-future novel biological immune targeted treatments, such as B cell-targeted therapy, cytokine blockade, peptide-based treatments and other novel treatments for SLE.

Background: Data on pediatric antiphospholipid syndrome (APS) are very sparse.

Objectives: To describe the main clinical characteristics, laboratory data and complications of pediatric APS patients, and to analyze the differences between primary APS and APS associated with systemic lupus erythematosus (SLE).

Methods: We retrospectively reviewed clinical and laboratory data of 32 children at “Federico Gomez,” the children’s hospital of México. Nineteen patients had SLE, 12 (37.5%) had primary APS and 1 (3%) had immune thrombocytopenic purpura. We collected information on sociodemographic variables, vaccinations, age at onset, and family history of rheumatic disease, hematological disorders, skin disorders and non-thrombotic neurological disorders. Immunological features included immunoglobulin (Ig) G and M aCl antibodies, IgG and IgM b2 glycoprotein I, lupus anticoagulant, anti-dsDNA and antinuclear antibodies.

Results: The patients included 24 females and 8 males. The most common thrombotic events were small vessel thrombosis (44%), venous thrombosis (28%) mainly deep venous thrombosis (DVT) in lower extremities, and arterial thrombosis (25%). The most common clinical non-thrombotic manifestations were hematological (53%) and neurological disorders (22%). There were no significant differences between groups with regard to the site of thrombosis, non-thrombotic clinical manifestations or laboratory features.

Conclusions: There were some important differences between the clinical manifestations of APS in children compared with adults, but we found no significant differences between patients with primary and APS associated with SLE. Larger studies in Latin American APS children are necessary to determine whether there are differences between ethnic groups.

 Background: The prevalence of vertebral fractures in systemic lupus erythematosus (SLE) ranges between 20% and 21.4%, and patients with these fractures have impaired walking and activities of daily living. Moreover, clinical and radiological vertebral fractures have been associated with increased mortality.
 Objectives: To compare the quality of life of patients with SLE[1] with and without vertebral fractures.

Methods: The study group comprised 140 women with SLE undergoing screening for vertebral fractures using a standardized method. SLE disease activity and organ damage were measured by the Mexican Systemic Lupus Erythematosus Disease Activity Index (MEX-SLEDAI) and Systemic International Collaborating Clinics/American College of Rheumatology damage index (SLICC), respectively. The QUALEFFO and Center for Epidemiologic Studies Depression Scale were used to measure health-related quality of life and depression, respectively.

Results: The median age of the 140 patients was 43 years (range 18–76); disease duration was 72 months (range 6–432); 49.7% were menopausal. Thirty-four patients (24.8%) had vertebral fractures (≥ 1), mostly in the thoracic spine. Patients with vertebral fractures had a higher mean age (49.5 ± 13.4 vs. 41 ± 13.2 years, P = 0.001) and disease damage (57.1% vs. 34.4%, P = 0.001). The global QUALEFFO score was not different between the vertebral fractures group and the non-vertebral group. The only significant difference in the QUALEFFO items was in physical function (P = 0.04). A significant correlation was found between the severity of vertebral fractures and the QUALEFFO pain (r = 0.27, P = 0.001) and physical function (r = 0.37, P = 0.02) scores. The number of vertebral fractures correlated only with physical function (r = 0.01).

Conclusions: The HRQOL of women with SLE is low, regardless of whether they have vertebral fractures or not, but patients with vertebral fractures have worse physical function compared to those without. Strategies to improve the HRQOL of patients with SLE with or without vertebral fractures are necessary.

In recent years the survival of patients with systemic lupus erythematosus has increased markedly. Consequently, long-term complications, such as osteoporosis, are currently of paramount importance. SLE[1] is known to increase the risk of bone fractures, and numerous studies have found that SLE patients have osteoporosis. Of the various risk factors associated with osteoporosis in SLE, disease duration, the use of corticosteroids and chronic disease-related damage are consistently reported, with differences between studies probably due to the different populations studied. The role of chronic inflammation in osteoporosis is also important. On the other hand, little attention has been paid to osteoporotic fractures, especially of the vertebra, which are associated with reduced quality of life, increased mortality rates and increased risk of new vertebral and non-vertebral fractures in the general population.
