Catastrophic antiphospholipid syndrome immediately after coronary angiography: the unexpected complication.

A 44-year-old woman with obstetric antiphospholipid syndrome (APS) presented to our institution with suspected non ST-elevation myocardial infarction (NSTEMI). Shortly after coronary angiography, she developed diplopia, hypotension and chest pain with inferior ST elevation in 12-lead ECG. According to multidisciplinary evaluation, she promptly underwent systemic thrombolysis, with clinical and haemodynamic improvement. Eventually, a diagnosis of catastrophic APS was made, with multiorgan ischemic involvement confirmed by blood examinations and multimodal imaging techniques. A pluridisciplinary approach was central to define optimal medical therapy and in-hospital management that lead to clinical condition improvement at discharge. In this case, catastrophic APS was triggered or worsened by catheters insertion and invasive manoeuvres within the arterial lumen during coronary angiography. Recognizing catastrophic APS and its potential triggers, can be helpful to deliver prompt and accurate medical assistance. Moreover, in APS patients undergoing coronary angiography, preventive strategies are important to prevent possible unfavourable evolution in catastrophic APS.

Potential role of serum mesothelin in predicting survival of patients with malignant pleural mesothelioma.

Malignant pleural mesothelioma (MPM) is an aggressive tumor with poor survival rates. Therefore, it is essential to have effective biological markers predicting the course of the disease and prognosis. The aim of the present study was to highlight the prognostic significance of serum soluble mesothelin-related protein (Se-SMRP) in patients with MPM at diagnosis. Se-SMRP was determined in 60 patients using an ELISA commercial kit. Se-SMRP levels were subdivided into three tertile-based categories and in each category overall survival (OS) indexes were determined using the Kaplan-Meier and Cox regression analyses. The association between Se-SMRP levels and OS was also assessed by restricted cubic spline (RCS) analysis. No notable differences in the Kaplan-Meier probabilities were identified across the Se-SMRP categories (<0.66 nM, 0.66-1.46 nM, >1.46 nM) although an upward trend in death rate ratios (RR) was pointed out by comparing the higher (RR=1.95) and intermediate (RR=1.86) categories with the lower category (RR=1.00). In addition, such an increasing tendency, particularly when the biomarker exceeded 1.0 nM, was confirmed by an RCS function of Se-SMPR levels fitted to survival data using the Cox regression equation. The present study provided evidence in favor of a prognostic value of Se-SMRP in patients with MPM.

Determination of Mesothelin Levels in Pleural Effusion Does Not Help Predict Survival of Patients With Malignant Pleural Mesothelioma.

AIM: This study evaluated the prognostic value of soluble mesothelin-related protein (SMRP) levels in pleural effusions (PE) from patients with pleural mesothelioma (MPM). PATIENTS AND METHODS: SMRP level in PE was tested using an enzyme-linked immunosorbent assay (ELISA) in 109 patients with MPM at diagnosis before any treatment. The Kaplan-Meier method and the Cox regression were applied to compare overall survival probabilities across tertile categories of SMRP level. RESULTS: No significant differences in Kaplan-Meier overall survival probabilities among the SMRP categories were found. A statistically non-significant trend for increased death rate ratio (RR) was computed (p=0.327) when the higher (>46.5 nM, RR=1.38) and intermediate (8.5-46.5 nM, RR=1.18) SMRP categories were compared to the lower category (<8.5 nM, RR=1.00). Cox regression modelling including a restricted cubic spline showed a moderately rising non-linear trend in death rate. CONCLUSION: The SMRP level in PE does not appear to have prognostic significance and its detection is not recommended in routine clinical management of patients with MPM.

Transplant-related mortality and long-term graft function are significantly influenced by cell dose in patients undergoing allogeneic marrow transplantation.

We have studied the impact of cell dose on short- and long-term graft function and outcome in 905 patients undergoing an unmanipulated allogeneic bone marrow transplantation (BMT) from an HLA-identical sibling (n = 735), a one-antigen mismatched related donor (n = 35), or a matched unrelated donor (n = 135). Median number of nucleated cells infused was 3.4 x 10(8)/kg (25th percentile 2.4 x 10(8)/kg, 75th percentile 5 x 10(8)/kg). Patients were stratified according to cells infused in 3 groups: < or = 2.4 x 10(8)/kg (n = 247; low dose); >2.4 x 10(8)/kg and < or = 5 x 10(8)/kg (n = 452; intermediate dose); and >5 x 10(8)/kg (n = 206; high dose). Patients receiving high cell dose had significantly higher platelet counts on days +20, +50, +100, +180, and +365 after BMT (P <.01) and higher white blood cell counts on days +50, +100, and +180 after BMT (P <.01) as compared with other patients. The actuarial 5-year transplant-related mortality (TRM) was 41% versus 36% versus 28% (P =.01); overall survival was 45% versus 51% versus 56% (P =.0008); and disease-free survival was 41% versus 42% versus 48%, respectively, (P =.04) in patients receiving low, intermediate, or high cell dose. The cell dose effect was more pronounced in patients older than 30 years of age, with advanced disease, with chronic myeloid leukemia, and with alternative donors. In multivariate Cox analysis on TRM, cell dose was a significant predictor (P =.002; relative risk 0.6) together with donor type (P =.0001), year of transplantation (P =.0001), conditioning regimen (P =.02), and recipient age (P =.02). In conclusion, transplantation of high marrow cell dose is associated with reduced transplant mortality and improved survival and results in improved graft function both short and long term.
