Abstract: In 90% of cases, women with rheumatoid arthritis suffer a disease flare within 3 months of delivery of their baby. Drug treatment is, therefore, required; however, such therapies have implications for mothers who decide to nurse their infants. Unfortunately, because of a paucity of data, little is known about the transfer of antirheumatic drugs into breast milk, and even less is known about whether small amounts of these agents ingested during nursing could harm the infant. Our review of the literature indicates that paracetamol, prednisone, antimalarial agents, sulfasalazine and most NSAIDs can safely be used by lactating mothers. Expert opinions differ regarding the use of azathioprine, ciclosporin, and methotrexate during lactation because of varying views on the potential for short-term and long-term adverse effects. Evidence regarding the transfer of leflunomide and biologic drugs into breast milk is insufficient; therefore, until more studies are conducted, the use of these drugs in breastfeeding mothers should be restricted. At present, many patients feel they have to choose between postpartum disease control and lactation. Extended studies of the transfer of antirheumatic drugs into breast milk and the resulting consequences are, therefore, urgently needed.

Abstract: Anti-Ro/SSA antibodies are associated with neonatal lupus but are also considered a possible cause for unexplained pregnancy loss and adverse pregnancy outcome. In a large multicentres cohort study we have prospectively followed 100 anti-Ro/SSA positive women (53 systemic lupus erythematosus (SLE)) during their 122 pregnancies and 107 anti-Ro/SSA negative women (58 SLE) (140 pregnancies). Anti-Ro/SSA antibodies were tested by immunoblot and counterimunoelectrophoresis. Mean gestational age at delivery (38 vs 37.9 weeks), prevalence of pregnancy loss (9.9 vs 18.6%), preterm birth (21.3 vs 13.9%), cesarean sections (49.2 vs 53.4%), premature rupture of membranes (4.9 vs 8.1%), preeclampsia (6.6 vs 8%), intrauterine growth retardation (0 vs 2.3%)and newborns small for gestational age (11.5 vs 5.8%) were similar in anti-Ro/SSA positive and negative SLE mothers; findings were similar in non-SLE women. Two cases of congenital heart block were observed out of 100 anti-Ro/SSA positive women. In conclusion, anti-Ro/SSA antibodies are responsible for congenital heart block but do not affect other pregnancy outcomes, both in SLE and in non-SLE women. The general outcome of these pregnancies is now very good, ifprospectively followed by multidisciplinary teams with ample experience in this field.

Abstract: Hyperhomocysteinemia (HH) has been associated with cardiovascular and autoimmune diseases and oxidative cell damage. Myelodysplastic syndromes (MDS) are associated with autoimmunity (AI) and increased oxidative stress. We tested the association of HH and oxidative stress in 33 MDS patients, by measuring plasma homocysteine and malondialdehyde (MDA). HH was found in 42% of cases, (4/5) cases with associated cardiovascular events (CVE)(80%), and 9/15 cases with associated AI (60%). Thus in MDS, HH was significantly associated with AI/CVE (chi(2) : p=0.0011), and this association seems to be specific, as demonstrated by the comparison of MDS presenting AI/CVE with the ischemic cardiopathy/rheumatoid arthritis control group (13/20, 65% vs 19/69, 27%; chi(2) : p=0.0021). The levels of MDA indicated increased oxidative stress. Our data may suggest that in a subset of MDS, HH may simultaneously contribute to bone marrow myelodysplasia, CVE and AI pathogenesis, possibly through oxidative cell damage.
