Medical practice is a form of art, with each complex detail essential to the welfare of the individuals in the care of the physician. Art and medicine have shared a close relationship in a variety of ways for centuries, as demonstrated by anatomical drawings and textbooks from the 16th century. Leonardo da Vinci, driven by his fascination with the details of the human body and how it functioned, succeeded in creating an anatomical model of the cerebral ventricles and the aorta using molten wax and a glass structure, respectively (Heart and Its Blood Vessels). By using water that contained grass seeds, this experiment enabled him to study blood flow. da Vinci’s engrossment with the complexity of the human body is reflected in many of his drawings, including the famous depiction of the human physique in his drawing of the Vitruvian Man. This drawing, which defines the ideal proportions of the human body and their correlation with geometry, is an example of how artistic and scientific objectives integrate with each other.

Background: Anti-BLyS treatment with the human belimumab monoclonal antibody was shown to be a safe and effective therapeutic modality in lupus patients with active disease (i.e., without significant neurological/renal involvement) despite standard treatment.

Objectives: To evaluate the “real-life” safety and efficacy of belimumab added to standard therapy in patents with active lupus in five Israeli medical centers.

Methods: We conducted a retrospective open-labeled study of 36 lupus patients who received belimumab monthly for at least 1 year in addition to standard treatment. Laboratory tests (C3/C4, anti dsDNA autoantibodies, chemistry, urinalysis and complete blood count) were done every 3–4 months. Adverse events were obtained from patients’ medical records. Efficacy assessment by the treating physicians was defined as excellent, good/partial, or no response.

Results: The study group comprised 36 lupus patients (8 males, 28 females) with a mean age of 41.6 } 12.2 years. Belimumab was given for a mean period of 2.3 } 1.7 years (range 1–7). None of the patients discontinued belimumab due to adverse events. Four patients (11.1%) had an infection related to belimumab. Only 5 patients (13.9%) stopped taking belimumab due to lack of efficacy. The response was excellent in 25 patients (69.5%) and good/partial in the other 6 (16.6%). Concomitantly, serological response (reduction of C3/C4 and anti-dsDNA autoantibodies) was also observed. Moreover, following belimumab treatment, there was a significant reduction in the usage of corticosteroids (from 100% to 27.7%) and immunosuppressive agents (from 83.3% to 8.3%).

Conclusions: Belimumab, in addition to standard therapy, is a safe and effective treatment for active lupus patients.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease with multiorgan involvement and wide variability in presentation and course. Although it can appear at any age, women of childbearing age are primarily affected. This has led to the proposal of a hormonal role in the development of SLE. Among the main hormones shown to have immunomodulatory effects are estradiol, progesterone and prolactin.

Objectives: To report the levels of estradiol and prolactin in SLE patients and establish the relationship between these levels and disease activity, and to determine whether the phases of the menstrual cycle influence the activity of SLE and its relationship to hormone levels.

Methods: In this cross-sectional study, we examined 60 women with SLE. We measured disease activity using SLEDAI and BILAG. We obtained peripheral blood samples to determine the levels of estradiol, progesterone, and prolactin. 

Results: Patients’ age ranged between 16 and 65 years and the mean disease duration was 5.5 years (0–20). SLE was active (SLEDAI > 6) in 13 patients and inactive in 47. Thirty patients were in a pre-ovulatory menstrual cycle phase, 13 in a post-ovulatory cycle, and 17 were menopausal. We found a significant association between C4 levels and disease activity (P = 0.01) and between estradiol levels and disease activity in the kidney (P = 0.04). We did not find hyperprolactinemia in any patient. 

Conclusions: In this population, we found an association between estradiol levels and organ-specific activity in the kidney. One may speculate as to whether our population might benefit from the implementation of anti-estrogen therapy for control of disease activity, particularly in the kidney.

 

Physical, mental and social well-being are important outcomes in patients with chronic rheumatic diseases, including systemic lupus erythematosus (SLE). The MOS SF-36 and the WHO QoL Bref are appropriate for assessing quality of life (QoL) in patients with SLE.  The QoL of patients with SLE is impaired compared with that of controls. Fibromyalgia adversely affects the QoL of SLE patients. Women with SLE had significantly lower scores on subscales of the sense of coherence (SoC) compared with matched controls. This reduced SoC in SLE women represents impaired adaptive coping and is independently associated with reduced QoL in women with SLE. Depression and anxiety are common among SLE patients, and the frequency is similar to that in patients with rheumatoid arthritis. A reciprocal longitudinal relationship between depression and illness intrusiveness was found in patients with SLE. Disease activity and damage are not associated with depression. The subjective experience, not the illness per se, causes depression.

There is growing interest in the contribution of vitamin D deficiency to autoimmunity. Several studies have shown an association between low levels of vitamin D and autoimmune disorders, including multiple sclerosis, rheumatoid arthritis, type 1 diabetes, autoimmune thyroid diseases, celiac disease, and systemic lupus erythematosus (SLE). Vitamin D receptor ligands can mediate immunosuppressive effects. It has been suggested that low levels of this hormone contribute to the immune activation in lupus and other autoimmune diseases. This review updates and summarizes the literature on the association between vitamin D and SLE, and discusses the various correlations between vitamin D and SLE activity, clinical expressions, serology, and gene polymorphisms of vitamin D receptors.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease with a high degree of variability at onset, making it difficult to reach a correct and prompt diagnosis.

Objectives: To present the difficulties faced by the clinician in making a SLE diagnosis, based on the characteristics at study entry of an Italian cohort of SLE patients with recent onset as compared to two similar cohorts.

Methods: Beginning on 1 January 2012 all patients with a diagnosis of SLE (1997 ACR criteria) and a disease duration less than 12 months were consecutively enrolled in a multicenter prospective study. Information on clinical and serological characteristics was collected at study entry and every 6 months thereafter.

Results: Our cohort consisted of 122 patients, of whom 103 were females. Among the manifestations included in the 1997 American College of Rheumatology (ACR) criteria, cutaneous, articular and hematologic symptoms were the most prevalent symptoms at study entry.

Conclusions: Data from the literature confirm that the diagnosis of SLE is challenging, and that SLE is a severe disease even at onset when a prompt diagnosis is necessary for initiating the appropriate therapy.
