Long-term Outcome of Children Born to Women with Autoimmune Rheumatic Diseases: A Multicentre, Nationwide Study on 299 Randomly Selected Individuals.

The concern about the offspring's health is one of the reasons for a reduced family size of women with rheumatic diseases (RD). Increased risk of autoimmune diseases (AD) and neurodevelopmental disorders (ND) has been reported in children born to patients with RD. Within a nationwide survey about reproductive issues of women with RD, we aimed at exploring the long-term outcome of their children. By surveying 398 patients who received their diagnosis of RD during childbearing age (before the age of 45), information about the offspring were obtained from 230 women who declared to have had children. A total of 148 (64.3%) patients were affected by connective tissue diseases (CTD) and 82 (35.7%) by chronic arthritis. Data on 299 children (156 males, 52.1%; mean age at the time of interview 17.1 ± 9.7 years) were collected. Twelve children (4.0%), who were born to patients with CTD in 75% of the cases, were affected by AD (8 cases of celiac disease). Eleven children had a certified diagnosis of ND (3.6%; 6 cases of learning disabilities); 9 of them were born to mothers with CTD (5 after maternal diagnosis). No association was found between ND and prenatal exposure to either maternal autoantibodies or anti-rheumatic drugs. Absolute numbers of offspring affected by AD and ND were low in a multicentre cohort of Italian women with RD. This information can be helpful for the counselling about reproductive issues, as the health outcomes of the offspring might not be an issue which discourage women with RD from having children.

Disease activity assessment of rheumatic diseases during pregnancy: a comprehensive review of indices used in clinical studies.

Pregnancy requires a special management in women with inflammatory rheumatic diseases (RDs), with the aim of controlling maternal disease activity and avoiding fetal complications. Despite the heterogeneous course of RDs during pregnancy, their impact on pregnancy largely relates to the extent of active inflammation at the time of conception. Therefore, accurate evaluation of disease activity is crucial for the best management of pregnant patients. Nevertheless, there are limitations in using conventional measures of disease activity in pregnancy, as some items included in these instruments can be biased by symptoms or by physiological changes related to pregnancy and the pregnancy itself may influence laboratory parameters used to assess disease activity. This article aims to summarize the current literature about the available instruments to measure disease activity during pregnancy in RDs. Systemic lupus erythematosus is the only disease with instruments that have been modified to account for several adaptations which might interfere with the attribution of signs or symptoms to disease activity during pregnancy. No modified-pregnancy indices exist for women affected by other RDs, but standard indices have been applied to pregnant patients. The current body of knowledge shows that the physiologic changes that occur during pregnancy need to be either adapted from existing instruments or developed to improve the management of pregnant women with RDs. Standardized instruments to assess disease activity during pregnancy would be helpful not only for clinical practice but also for research purposes.

"Disease knowledge index" and perspectives on reproductive issues: A nationwide study on 398 women with autoimmune rheumatic diseases.

OBJECTIVE: The reproductive choices of women affected by rheumatic diseases (RD) can be influenced by several factors, including the quality of physician-patient communication. We conducted a survey on reproductive issues aiming at exploring the unmet needs of women with RD during childbearing age. METHODS: We administered 65 multiple-choice and 12 open-answer questions about pregnancy counselling, contraception, use of drugs during pregnancy and other women reproductive issues to 477 consecutive women with RD aged 18-55 years followed-up in 24 rheumatology centres in Italy. Analysis was restricted to 398 patients who received their diagnosis of RD before the age of 45. According to the RD diagnosis, patients were subdivided into 2 groups: connective tissue diseases (n = 249) and chronic arthritis (n = 149). RESULTS: At the time of interview, women in both groups had a mean age of 40 years. Nearly one third of patients in each group declared not to have received any counselling about either pregnancy desire nor contraception. A smaller family size than desired was reported by nearly 37% of patients, because of concerns related to maternal disease in one fourth of the cases. A "Disease Knowledge Index" (DKI) was created to investigate the degree of patients' information about the implications of their RD on reproductive issues. Having received counselling was associated with higher DKI values and with a positive impact on family planning. CONCLUSION: Italian women of childbearing age affected by RD reported several unmet needs in their knowledge about reproductive issues. Strategies are needed to implement and facilitate physician-patient communication.

Pregnancy in systemic sclerosis.

This comprehensive review summarizes retrospective and prospective studies on pregnancy in systemic sclerosis in order to educate physicians on critical management issues. Fertility is normal in women with established systemic sclerosis. Their rates of spontaneous losses are comparable to the general population, except for patients with late diffuse systemic sclerosis and severe internal organ involvement who may have higher risks of abortion. Prematurity is clearly higher among systemic sclerosis women, similarly to other rheumatic diseases such as systemic lupus erythematosus and anti-phospholipid antibody syndrome. A placental vasculopathy has been observed in some women with systemic sclerosis. Overall, the disease generally remains stable in most pregnancies. Women with pulmonary hypertension should avoid pregnancy on account of the high maternal mortality risk. Management of systemic sclerosis patients before and during pregnancy includes evaluation of organ involvement and autoantibody analysis, preconceptional folic acid, and discontinuation of drugs with teratogenic potential (bosentan, mycophenolate mofetil, methotrexate, etc.). Management by high-risk pregnancy teams including neonatologists is very important to ensure the best outcomes.

Steroids and Autoimmunity.

From the middle of the 19th century, it is known that endocrine and immune systems interact bi-directionally in different processes that ensure organism homeostasis. Endocrine and nervous systems have a pivotal role in the balancing of pro- and anti-inflammatory functions of immune system, and constitute a complex circadian neuroendocrine network. Autoimmune diseases have in fact a complex pathogenic origin in which the importance of endocrine system was demonstrated. In this chapter, we will mention the structure and function of steroidal hormones involved in the neuroendocrine immune network and we will address the ways in which endocrine and immune systems influence each other, in a bi-directional fashion. Adrenal hormones, sex hormones, vitamin D, and melatonin and prolactin importantly all contribute to the homeostasis of the immune system. Indeed, some of the steroidal hormone activities determine inhibition or stimulation of immune system components, in both physiological (i.e. suppression of an unwanted response in pregnancy, or stimulation of a protective response in infections) and pathological conditions. We will finally mention the rationale for optimization of exogenous administration of glucocorticoids in chronic autoimmune diseases, and the latest developments concerning these drugs.

Quantitative Alterations of Capillary Diameter Have a Predictive Value for Development of the Capillaroscopic Systemic Sclerosis Pattern.

OBJECTIVE: To quantify earlier capillary diameter abnormalities, observed by nailfold videocapillaroscopy (NVC), in primary Raynaud phenomenon (PRP) subjects compared with RP subjects later evolved to systemic sclerosis (SSc)-associated secondary Raynaud phenomenon (SRP). METHODS: There were 6112 NVC images of 191 subjects analyzed at baseline and after a mean followup of 42.77 ± 35.80 months. We selected 48 patients affected by SRP and 143 matched controls confirmed with PRP. The diameter of the most dilated limbs (arterial, venous, and apical) was measured in 16 images per subject. Statistical analysis was performed using nonparametric tests. The threshold values for capillary diameters associated with the development of SSc-associated SRP were determined through receiver-operating characteristic curves. RESULTS: Mean capillary diameter values were significantly different for arterial, venous, and average diameters (mean value of arterial, venous, and apical) between patients with PRP and SRP (p < 0.0001). These alterations were found to be independent predictors for disease development (p = 0.015). Threshold values of 30 µm (area under the curve = 0.802, sensitivity/specificity = 0.85/0.63) to 31 µm were identified for average, arterial, and venous diameters, with a shortening effect on time to disease development. CONCLUSION: The study showed that capillary diameter is an independent predictor for development of SSc-associated SRP. Progression to SRP is unlikely for subjects affected by RP when average capillary diameter is under 30 µm. Subsequently, the execution of the qualitative/quantitative integrated analysis should be part of the NVC followup of RP subjects.

Clinical utility of the oral JAK inhibitor tofacitinib in the treatment of rheumatoid arthritis.

Immune/inflammatory cells act in rheumatoid arthritis (RA)-affected patients by synthesizing several inflammatory mediators, including cytokines that initiate intracellular signaling. Recently, small molecule inhibitors of transduction and transcription signals that influence the intracellular pathways (such as the Janus kinase [JAK] family of tyrosine kinases) have been tested for RA treatment. Four members of the JAK family are known: JAK1, JAK2, JAK3, and TyK2. JAK1/JAK3 constitutively binds to the cytoplasmic portion of the cytokine receptor - the common gamma chain - that represents a common subunit of several cytokines involved in T-cell and natural killer cell development, as well as in B-cell activation. Tofacitinib is an oral JAK inhibitor that is now available and effective in RA treatment, as shown in multiple Phase II and Phase III clinical trials. However, long-term safety data and comparisons with other disease-modifying antirheumatic drugs and small molecule inhibitors are necessary to better determine the role of tofacitinib in RA.

Brief report: successful pregnancies but a higher risk of preterm births in patients with systemic sclerosis: an Italian multicenter study.

OBJECTIVE: To assess fetal and maternal outcomes in women with systemic sclerosis (SSc). METHODS: Prospectively collected data on 99 women with SSc from 25 Italian centers were analyzed retrospectively. Women with SSc were observed during 109 pregnancies (from 2000 to 2011), and outcomes were compared to those in the general obstetric population (total of 3,939 deliveries). The maternal age at conception was a mean ± SD 31.8 ± 5.3 years, and the median disease duration at conception was 60 months (range 2-193 months). RESULTS: SSc patients, compared to the general obstetric population, had a significantly increased frequency of preterm deliveries (25% versus 12%) and severe preterm deliveries (<34 weeks of gestation) (10% versus 5%), intrauterine growth restriction (6% versus 1%), and babies with very-low birth weight (5% versus 1%). Results of multivariable analysis showed that corticosteroid use was associated with preterm deliveries (odds ratio [OR] 3.63, 95% confidence interval [95% CI] 1.12-11.78), whereas the use of folic acid (OR 0.30, 95% CI 0.10-0.91) and presence of anti-Scl-70 antibodies (OR 0.26, 95% CI 0.08-0.85) were protective. The disease remained stable in most SSc patients, but there were 4 cases of progression of disease within 1 year from delivery, all in anti-Scl-70 antibody-positive women, 3 of whom had a disease duration of <3 years. CONCLUSION: Women with SSc can have successful pregnancies, but they have a higher-than-normal risk of preterm delivery, intrauterine growth restriction, and babies with very-low birth weight. Progression of the disease during or after pregnancy is rare, but possible. High-risk multidisciplinary management should be standard for these patients, and pregnancy should be avoided in women with severe organ damage and postponed in women with SSc of recent onset, particularly if the patient is positive for anti-Scl-70 antibodies.

Estrogens interfere with leflunomide modulation of cytokine production by human activated monocytes.

Rheumatoid arthritis (RA) prevalence is greater in females than in males, supporting estrogens as modulators of immune response. Leflunomide (LEF) is employed in the RA treatment. We studied the combinatory effects of LEF active metabolite A77 1726 (LEF-M) and 17beta-estradiol (E2) on inflammatory cytokine production by cultured macrophages obtained from activated human monocytes (THP-1 cells). Macrophages were cultured with LEF-M alone and in combination with E2. IL-6, TNF-alpha, and TGF-beta were evaluated by immunocytochemistry (ICC), Western blot (WB), and reverse transcriptase-polymerase chain reaction (RT-PCR). ICC, as well as WB and RT-PCR, showed that LEF-M, in respect to untreated cells, significantly downregulated the cytokine production (IL-6 P < 0.01, TNF-alphaP < 0.001, TGF-betaP < 0.01). On the contrary, E2 increased the cytokine production, a result that was significantly reversed when LEF-M was subsequently added (IL-6, TNF-alpha, TGF-betaP < 0.001 vs. E2). E2 seems to contrast the LEF-M activity. These results might support a more efficient therapeutical effect of LEF in male with respect to female RA patients.
