For My Patients

Publications by Dr. Sammaritano

Use of estrogen in systemic lupus:

Systemic lupus patients were traditionally counselled to avoid exogenous estrogens due to presumed risk of lupus flare; this concern was based on animal studies, in vitro experiments and isolated case reports. I was one of the investigators that originated and designed a multicenter study that evolved into the SELENA study (Safety of Estrogens in Lupus Erythematosus – National Assessment). Patients were entered into one of two studies, the first evaluated estrogen-progesterone oral contraceptives in reproductive-aged women with lupus, and the second evaluated hormone replacement therapy in postmenopausal lupus patients. These two studies demonstrated a minimal risk of flare with exogenous estrogen in stable lupus patients without antiphospholipid antibodies.

Buyon JP, Petri MA, Kim MY, Kalunian KC, Grossman J, Hahn BH, Merrill JT, Sammaritano L, Lockshin M, Alarcon GS, Manzi S, Belmont HM, Askanase AD, Sigler L, Dooley MA, Von Feldt J, McCune WJ, Friedman A, Wachs J, Cronin M, Hearth-Holmes M, Tan M, Licciardi F. The effect of combined estrogen and progesterone hormone replacement therapy in systemic lupus erythematosus: a randomized trial. Ann Intern Med 2005;142(12):953-62.

Combined oral contraceptives in women with systemic lupus erythematosus.  N Engl J Med 2005; 353(24):2550-8.

Athersclerosis in women with lupus:

Women with lupus have been demonstrated to have earlier onset of atherosclerotic disease and etiology of this has been debated. Factors such as prolonged corticosteroid use, hypertension, and hyperlipidemia are more common in SLE and may contribute to early and severe atherosclerosis. A cohort of women with SLE at Hospital for Special Surgery were evaluated with detailed laboratory and serologic testing, carotid doppler ultrasound and echocardiography and analysis of these data confirmed an independent effect of SLE on atherosclerotic risk

Lupus and Antiphospholipid Syndrome pregnancy outcomes:

Patients with SLE have higher risks of adverse pregnancy outcomes than do those in the general population. Concerns include increased risk of lupus flare, progression of renal disease, and increased rates of miscarriage, stillbirth, preeclampsia and eclampsia, preterm birth and intrauterine growth restriction. The PROMISSE study Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Antibody Syndrome and Systemic Lupus) is a multicenter observational study of women with SLE and aPL antibody; goals included identification of clinical risk factors and determination of possible biomarkers for poor outcome.  Results have identified important clinical risk factors (including lupus anticoagulant and disease activity) as well as demonstrated biomarkers that are associated with adverse outcome.

American College of Rheumatology Reproductive Health Guideline:

Patient with rheumatic and musculoskeletal diseases (RMD) face significant challenges in management of reproductive health, from choice of contraception to planning and management of pregnancy. The American College of Rheumatology has recognized this and developed an evidence-based clinical guideline to aid rheumatologists in assessing and co-managing reproductive health needs for these patients.
