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.

IL-23A, IL-23R, IL-17A and IL-17R polymorphisms in different psoriatic arthritis clinical manifestations in the northern Italian population.

To investigate the genetic variability of IL-17A, IL17-RA, IL-23A and IL-23R genes on an in-depth phenotypically characterized northern Italian Psoriatic arthritis (PsA) case-control cohort, in search for associations specific to different PsA clinical sub-phenotypes. We examined 118 patients with PsA according to CASPAR criteria (mean age 57 ± 13, female 38.4 %, mean disease duration 13.9 ± 8.6 years, peripheral disease 83.8 %, axial manifestations 34.5 %, radiological erosive disease 49 %) compared with 248 controls of the same ethnic origin matched for age and sex. The presence of axial disease was defined by the clinical axial involvement and/or the presence of radiological alteration consistent with spondyloarthropathy according to New York criteria. The presence of peripheral disease (arthritis and/or enthesitis) was defined only on clinical basis. A total of 40 SNPs, mapping within the genes mentioned above, were genotyped in both groups and used to perform association analyses by subdividing the PsA sample into subgroups according to different clinical manifestations on the basis of axial and peripheral involvements. No differences between patients and controls were found in the distribution of the IL-17A, IL17-RA, IL-23A and IL-23R genes allelic variants. Comparing patients with axial disease versus those without, we found that axial manifestations were significantly associated with the presence of IL-23R rs12401432 GG homozygosity (26.8 % vs. 5.3 %, p corr = 0.019, OR 2.63 [95 % CI 1.13-6.16]). No differences in distribution of the allelic variants were found comparing patients with versus those without peripheral disease or patients with versus without radiological peripheral erosions. In PA patients of northern Italian origin, IL-17A, IL17-RA, IL-23A and IL-23R genes allelic variants are not associated with disease susceptibility. However, a strong association with the IL-23RA rs12401432 GG genotype is associated with axial involvement of the disease.

Adalimumab in psoriatic arthritis.

Open prospective studies and randomized controlled trials (RCT) have shown the short-term efficacy of adalimumab (ADA) in psoriatic arthritis (PsA) and psoriasis. ADA effectively treated all varied musculoskeletal manifestations characteristic of PsA, including peripheral arthritis, spinal disease, enthesitis, and dactylitis. ADA significantly inhibited structural changes on radiographs, lessened disability, and improved quality of life in patients with active PsA. One study showed the efficacy of 24-week ADA therapy on bone marrow edema and erosions, as measured by magnetic resonance imaging. The clinical and radiographic efficacy of ADA demonstrated during short-term treatment was sustained during longterm treatment. ADA was generally well tolerated and its safety profile was similar to that reported in studies of ADA in rheumatoid arthritis. Overall, ADA has a favorable risk-benefit profile in PsA. The combination of ADA and cyclosporine seems to be more effective than ADA monotherapy in patients with active PsA and inadequate response to methotrexate; however, this observation must be confirmed in RCT.
