Effective and safe off-label use of caplacizumab treatment in a middle-aged obese male.

This study shows clinical efficacy and safety profile of an off-label use of caplacizumab for the treatment of immune-mediated thrombotic thrombocytopenic purpura in a middle-aged obese male patient manifesting aphasia, weakness and unconsciousness. Routine blood tests revealed haemolytic anaemia, severe thrombocytopenia (platelet count=20×109/L) and moderate creatinine increase. Diagnosis was based on the clinical judgement and laboratory determinations (undetectable ADAMTS13 activity and presence of anti-ADAMTS13 antibodies). The patient underwent plasma-exchange and an adjunctive treatment with prednisone (1mg/Kg/day), but the occurrence of a refractory and exacerbated form of disease suggested also using rituximab (375mg/m2 weekly for 4 weeks) and caplacizumab as salvage treatments. The caplacizumab was given at 10mg/day subcutaneously without the first intravenous bolus. Because von Willebrand factor inhibition, platelet count recovery and remission of symptoms were achieved, use of caplacizumab with this scheme appeared to be as effective as the approved one. Although this is an off-label use, this case highlights the potential of this new treatment, in terms of drug's efficacy and safety.

Low-molecular -weight heparin in pregnancies after ART -a retrospective study-.

INTRODUCTION: The utility of an antithrombotic prophylaxis in Assisted Reproductive Technologies (ART) is highly debated. It has been hypothesised that specific effects of heparin on the coagulation system during implantation can improve the number of clinical pregnancies and live births. MATERIALS AND METHODS: We studied a cohort of 327 women undergone at least 1 ART cycle before thrombophilia testing. Overall, a number of 751cycles was analysed. Low-Molecular-Weight Heparin (LMWH) and/or low-dose aspirin (ASA) were prescribed in 132 (17.6%) cycles. Furthermore, all the women underwent thrombophilia screening. RESULTS: The univariate analysis showed that LMWH with/without ASA was significantly associated with both the outcomes clinical pregnancy and live birth, while the use of ASA was not associated with live birth. The logistic regression showed that the use of LMWH was significantly associated with both the outcomes, clinical pregnancy (OR: 6.0, 95%CI: 2.8-15.6) and live birth (OR: 10.7, 95%CI: 3.2-36.1). The type of ART procedure significantly influenced the likelihood of achieving clinical pregnancy. CONCLUSIONS: Present findings suggest that LMWH alone or combined with ASA could have a role in fostering the implantation of embryos and improving the number of live births after ART.

Risk of obstetric and thromboembolic complications in family members of women with previous adverse obstetric outcomes carrying common inherited thombophilias.

BACKGROUND: Factor (F)V Leiden and the prothrombin 20210A mutation (PTm) are associated with the occurrence of obstetric complications, including pregnancy-related venous thromboembolism (VTE). It is not known whether family members of women with FV Leiden or PTm and previous obstetric complications have a higher risk of VTE or adverse obstetric outcomes. METHODS: A retrospective family study including 563 relatives of 177 women with previous adverse outcomes carrying FV Leiden or PTm, referred between April 1993 and June 2010. A history of obstetric complications and VTE was obtained. Prevalence of VTE and obstetric complications in relatives with and without inherited thrombophilias was compared. Adjusted odd ratios (OR) and 95% confidence intervals (CI) were calculated using logistic regression models that controlled for predictors (age, FV Leiden and PTm). RESULTS: Relatives carrying FV Leiden had a significant and independent risk for obstetric complications (OR: 1.98, 95% CI 1.03-3.83); this risk was not observed in the presence of PTm (OR: 1.03, 95% CI 0.46-2.32). The presence of FV Leiden or PTm in heterozygosis was significantly and independently associated with the occurrence of VTE (OR: 5.2, 95% CI: 1.70-15.91). Severe thrombophilias were strong risk factors for VTE (OR: 23.2, 95% CI: 6.0-89.85). Male gender was a significant and independent risk factor for VTE (OR: 3.49, 95% CI: 1.51-8.05). The risk did not change when relatives of women with a previous pregnancy-related VTE were excluded (OR: 3.49, 95% CI: 1.51-8.05). CONCLUSIONS: Knowledge of thrombophilia status may help to better define the obstetric and thromboembolic risks in asymptomatic family members of women who suffered from obstetric complications.

Digitized images of wounds: a nursing practice innovation.

Although clinical photography is not new, the incorporation of digital wound images into computerized patient records is an innovation recently developed in nursing practice. At the Washington, DC Veterans Affairs Medical Center (Washington DC VAMC), a nurse imaging program is being developed through a unique partnership between a clinical nurse specialist and a nurse informaticist. Digitized images are stored as parts of the ViastA computerized patient record system, making them immediately available throughout the entire medical center, on more than 1500 computers in the clinical environment. Any patient condition that can be represented visually, for example, pressure ulcers, which are the most frequently imaged, can be placed into the medical record. The major benefit of this nurse imaging program is that the status of wound healing can be tracked visually over time, from acute care to the clinic setting, and to the home. Progression from the problem, as originally defined, through the innovation process, and a statement of future plans are presented in the article.

Welfare-to-work training: a public/private partnership that shapes the nation.

The nursing service of the James A. Haley Veterans' Hospital (Tampa, FL) was one of the first to join with public and private community agencies to develop a welfare-to-work program. The results of this joint effort have produced a recruitment, training, and preceptorship program that has successfully filled the need for certified nursing assistants, identified the hospital as a source of certified nursing assistants, and provided the opportunity to support local and national welfare-to-work initiatives.

Analysis of serum and plasma beta chemokines in primary HIV infection (PHI).

The levels of certain beta-chemokines in biological fluids do not necessarily reflect their circulating concentrations as they may be dramatically influenced by ex vivo release during sample manipulation. In the present study beta-chemochine levels were evaluated in sequential paired plasma and serum samples collected from a cohort of 18 patients with primary HIV infection (PHI), as well as from 17 HIV-seronegative individuals. In plasma of PHI patients, a significant increase of RANTES (mean 119.1 vs 15.85 ng/ml; p=0.0001) and MIP-1beta (mean 53.4 pg/ml vs 33.6 pg/ml; p=0.0001) was documented. Intra-patient covariance analysis demonstrated no significant association between the variations of RANTES in plasma and serum or between RANTES levels and platelet counts. Reproducibility tests of RANTES measurements in plasma from PHI patients showed a mean coefficient of variation of 1.8%. These data demonstrate that the plasma levels of RANTES and, to a lesser extent, MIP-1beta are persistently perturbed during the early phase of HIV infection. Furthermore they indicate that plasma and serum levels are not directly correlated, being influenced by different physiological phenomena that occur during the ex vivo preparation procedures of the two biological fluids.

Interaction between nonsteroidal anti-inflammatory drugs and high-dose methotrexate: a literature review.

An important step in preventing methotrexate (MTX) toxicity is to assess patient self-medication of over-the-counter drugs before high-dose methotrexate (HD-MTX) treatment is administered. Nonsteroidal anti-inflammatory drugs given within a 10-day period before a patient receives HDMTX leads to a decreased MTX excretion rate causing MTX toxicity. Education of the nursing staff and patients and their families is vital to avoid the potentially dangerous effects of a delayed MTX excretion rate.

Incongruence between self-reported symptoms and objective evidence of respiratory disease among construction workers.

In clinical settings, self-reported symptoms and objective evidence of disease may be poorly correlated. In the present study, symptoms and objective evidence of pulmonary disease were compared in a community sample of construction workers with occupational exposure to asbestos. Symptoms of dyspnea and cough were assessed by a standardized questionnaire. The clinical examination included a chest X-ray, pulmonary function testing (PFT), and a physical examination. Both symptoms and objective clinical findings were strongly related to years in these trades. However, less than 1% of workers reported symptoms in the absence of any clinical evidence of disease. A similar low percentage of workers denied any symptoms yet produced clear evidence of pulmonary disease on clinical examination. Results were interpreted in terms of the variety of factors which have been associated with patients' readiness, and conversely, reluctance to report symptoms. The comparatively low frequency of incongruence between symptoms and objective clinical findings in this study suggests over emphasis of malingering by other authors. Health care might be improved if more attention is given by clinicians and researchers to patients who fail to report symptoms in the presence of disease.
