RESUMEN

Resumen El presente caso corresponde a una mujer con antecedentes de tres abortos de menos de 10 semanas y cáncer de mama, que desarrolló isquemia digital grave luego del segundo ciclo de capecitabina. Se determinó la presencia de anticuerpos antifosfolipídicos positivos. Dado que las pacientes con síndrome antifosfolipídico obstétrico tienen incremento del riesgo de desarrollar neoplasia y que la isquemia digital grave puede ser la forma de presentación del síndrome antifosfolipídico en los pacientes con cáncer, se presenta el caso para remarcar el beneficio de pesquisar y realizar un diagnóstico temprano de estas características de la enfermedad.

Abstract The present case corresponds to a woman with history of three miscarrieges less than10 weeks and breast cancer, who develops severe digital ischemia after the second cycle of capecitabine. Positive antiphospholipid antibodies were determined. Patients with obstetric antiphospholipid syndrome have an increased risk of developing cancer, and severe digital ischemia could be an unusual form of presentation of the antiphospholipid syndrome in patients with cancer. This case is presented to highlight the benefit of researching and making an early diagnosis of these characteristics of the disease.

RESUMEN

OBJECTIVE: Calcinosis is a debilitating complication of systemic sclerosis (SSc) with no effective treatments. We sought to identify clinical correlations and to characterize complications and disability associated with calcinosis in a multi-center, international cohort of SSc patients. METHODS: We established a cohort of 568 consecutive SSc patients who fulfill 2013 revised ACR/EULAR criteria at 10 centers within North America, Australia, and Mexico. Calcinosis was defined as subcutaneous calcium deposition by imaging and/or physical examination, or a clear history of extruded calcium. All patients completed the Scleroderma Health Assessment Questionnaire Disability Index and Cochin Hand Functional Scale. RESULTS: 215 (38%) patients had calcinosis. In multivariable analysis, disease duration (OR=1.24, p = 0.029), digital ischemia (OR=1.8, p = 0.002) and Acro-osteolysis (OR=2.97, p = 0.008) were significantly associated with calcinosis. In the subset of patients with bone densitometry (n = 68), patients with calcinosis had significantly lower median T-scores than patients without (-2.2 vs. -1.7, p = 0.004). The most common location of calcinosis lesions was the hands (70%), particularly the thumbs (19%) with decreasing frequency moving to the fifth fingers (8%). The most common complications were tenderness (29% of patients) and spontaneous extrusion of calcinosis through the skin (20%), while infection was rare (2%). Disability and hand function were worse in patients with calcinosis, particularly if locations in addition to the fingers/thumbs were involved. CONCLUSIONS: We confirmed a strong association between calcinosis and digital ischemia. Calcinosis in SSc patients most commonly affects the hands and is associated with a high burden of disability and hand dysfunction.
