Safety of Abatacept in Rheumatoid Arthritis With Serologic Evidence of Past or Present Hepatitis B Virus Infection.

OBJECTIVE: Rheumatoid arthritis (RA) with concomitant hepatitis B virus (HBV) infection represents a therapeutic challenge due to the risk of HBV reactivation under immunosuppressive treatment. To date there are few data coming from anecdotal case reports that concern HBV reactivation following treatment with abatacept. This observational retrospective study was aimed to assess the safety profile of abatacept in this particular clinical setting. METHODS: Eleven Italian rheumatologic centers provided data from patients with RA and positive HBV serology treated with intravenous abatacept. HBV markers and clinical and laboratory data were checked at followup visits every 3 months. RESULTS: In total, 72 patients were included in the study: 47 inactive carriers, 21 occult carriers, and 4 chronic active carriers for HBV. At baseline all of the patients had normal liver function tests and low or undetectable HBV DNA levels, except for those with chronic active hepatitis. Thirteen patients received prophylaxis with lamivudine, and 4 received treatment with adefovir or tenofovir. At the end of the 24-month followup period, 49 patients were being treated. Data from 316 followup visits showed that abatacept was safe. No patients experienced reactivation of hepatitis B. Treatment withdrawals (23 patients) were due to lack of efficacy, subject decision/lost at followup, or adverse events not related to HBV infection. CONCLUSION: Our study provides reassuring data about the safety profile of abatacept in RA with concomitant HBV infection without universal antiviral prophylaxis. Further prospective studies are needed to confirm these preliminary results.

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.

Cocaine-related peripheral vascular occlusive disease treated with iloprost in addition to anticoagulants and antibiotics.

We describe a case of acute ischemia of the 2nd, 3rd and 4th fingers of the right hand secondary to peripheral vascular occlusive disease induced by repeated intra-arterial cocaine injections. The complete occlusion of the distal arteries resolved following treatment with iloprost, a synthetic stable analogue of prostacyclin PGI2, in addition to anticoagulants and antibiotics.
