RESUMEN
OBJECTIVES: To evaluate the clinical characteristics of patients with interstitial lung disease (ILD) in the setting of a large cohort of systemic sclerosis (SSc) patients, and to analyse the differences according to the SSc subtype (following the modification of classification criteria of the American College of Rheumatology for SSc proposed by LeRoy and Medsger), factors are associated with moderate-to-severe impairment of lung function, as well as mortality and causes of death. METHODS: A descriptive study was performed, using the available data from the Spanish Scleroderma Study Group. RESULTS: Twenty-one referral centers participated in the registry. By April 2014, 1374 patients with SSc had been enrolled, and 595 of whom (43%) had ILD: 316 (53%) with limited cutaneous SSc (lcSSc), 240 (40%) with diffuse cutaneous SSc (dcSSc), and 39 (7%) with SSc sine scleroderma (ssSSc). ILD in the lcSSc and the ssSSc subsets tended to develop later, and showed a less impaired forced vital capacity (FVC) and a ground glass pattern on high-resolution computed tomography (HRCT) less frequently, compared with the dcSSc subset. Factors related to an FVC < 70% of predicted in the multivariate analysis were: dcSSc, positivity to anti-topoisomerase I antibodies, a ground glass pattern on HCRT, an active nailfold capillaroscopy pattern, lower DLco, older age at symptoms onset, and longer time between symptoms onset and ILD diagnosis. Finally, SSc-associated mortality and ILD-related mortality were highest in dcSSc patients, whereas that related to pulmonary arterial hypertension was highest in those with lcSSc-associated ILD. CONCLUSIONS: Our study indicates that ILD constitutes a remarkable complication of SSc with significant morbidity and mortality, which should be borne in mind in all three subgroups (lcSSc, dcSSc, and ssSSc).

Systemic sclerosis (SSc) is a rare, multisystem disease showing a large individual variability in disease progression and prognosis. In the present study, we assess survival, causes of death, and risk factors of mortality in a large series of Spanish SSc patients. Consecutive SSc patients fulfilling criteria of the classification by LeRoy were recruited in the survey. Kaplan-Meier and Cox proportional-hazards models were used to analyze survival and to identify predictors of mortality. Among 879 consecutive patients, 138 (15.7%) deaths were registered. Seventy-six out of 138 (55%) deceased patients were due to causes attributed to SSc, and pulmonary hypertension (PH) was the leading cause in 23 (16.6%) patients. Survival rates were 96%, 93%, 83%, and 73% at 5, 10, 20, and 30 years after the first symptom, respectively. Survival rates for diffuse cutaneous SSc (dcSSc) and limited cutaneous SSc were 91%, 86%, 64%, and 39%; and 97%, 95%, 85%, and 81% at 5, 10, 20, and 30 years, respectively (log-rank: 67.63, Pâ<â0.0001). The dcSSc subset, male sex, age at disease onset older than 65 years, digital ulcers, interstitial lung disease (ILD), PH, heart involvement, scleroderma renal crisis (SRC), presence of antitopoisomerase I and absence of anticentromere antibodies, and active capillaroscopic pattern showed reduced survival rate. In a multivariate analysis, older age at disease onset, dcSSc, ILD, PH, and SRC were independent risk factors for mortality. In the present study involving a large cohort of SSc patients, a high prevalence of disease-related causes of death was demonstrated. Older age at disease onset, dcSSc, ILD, PH, and SRC were identified as independent prognostic factors.

The therapeutic goals for a patient with newly diagnosed lupus nephritis should be to achieve a prompt renal remission, to avoid renal flares, to avoid chronic renal impairment, and to fulfil these objectives with minimal toxicity. An advance in the therapy of LN has been the introduction of concepts of induction of remission (by a sort course of vigorous immunosupression such as monthly intravenous cyclophosphamide) and maintenance of remission (by long-term administration of the same cytotoxic drug given less frequently or a potentially safer immunosupressant such as azathioprine). Mycophenolate mofetil may be an alternative to cyclophosphamide for induction and maintenance therapy of patients with proliferative LN. Optimal care of lupus nephritis patients should include non immunosuppressive measures such as the vigorous management of cardiovascular risk factors and the treatment of proteinuria.

INTRODUCTION: Anti-phospholipid antibodies (APA) may involve heart and valvular heart disease seems to be the most common clinical manifestation. OBJECTIVES: To study the prevalence and characteristics of valvular heart disease in a large patient population with anti-phospholipid syndrome (APS) and also to analyze the clinical and immunological profile of patients with valvular involvement compared with those without involvement. Patients and methods. Retrospective analysis of 113 patients diagnosed of APS. Eighty-one percent were females and the mean age was 39 years (SD:14). Sixty-two percent of patients were diagnosed of primary APS (70 patients) and the remaining 38% (43 patients) corresponded to patients with APS associated with systemic lupus erythematosus (SLE). The median follow-up of patients was 55 months (range: 7-144 months). The cardiologic assessment was performed by means of transthoracic echocardiogram. The study of anti-lupus anticoagulant (AL) was performed by means of coagulometric assays and measurement of anticardiolipin antibodies (aCL), anti-beta2 glycoprotein I (abeta2-PGI) and anti-prothrombin (aPT) by ELISA. RESULTS: The prevalence of valvular heart disease was 19%. The mitral valve was mostly involved (91%) and the most common structural abnormality corresponded to mitral insufficiency. Valvular replacement was required in 24% of patients. In the subgroup of patients with valvular heart disease, a significantly higher prevalence was observed in the following parameters: total thrombosis (71% versus 49%; p = 0.05), arterial thrombosis (57% versus 23%; p = 0.002), stroke (38% versus 13%; p = 0.01), trombocitopenia (71% versus 45%; p = 0.02), hemolytic anemia (29% versus 9%; p = 0.02), and livedo reticularis (48% versus 3%; p < 0.0001). As for immunological differences, only a higher prevalence of LA was found (81% versus 59%; p= 0.04) and abeta2-GPI (IgG isotype) (43% versus 22%; p = 0.05) in patients with valvular heart disease. CONCLUSIONS: Valvular heart disease is more frequent in pa-tients with APS and mitral insufficiency is the most common lesion. In a patient with the diagnosis of APS, an echocar-digram should be obtained in his/her initial assessment and regular controls should be obtained in the follow-up.
