Impact of immunosuppressive treatment on the cardiovascular system in patients after hand transplantation.

BACKGROUND: Cardiovascular disease is a major cause of mortality in solid organ allograft recipients. Hand transplantation is not a lifesaving procedure, thus the effect of long-term immunosuppression on the cardiovascular system in these patients should be monitored. The aim of this study was to evaluate the morphology and function of heart and blood vessels in patients after hand transplantation. METHODS: The study included 5 patients at ages 32 to 58 years, mean 39 years, who underwent hand transplantation between 2006 and 2010. Immunosuppressive treatment included basiliximab in induction and tacrolimus, mycophenolate mofetil, and prednisone. Cardiac status was assessed by echocardiography (according to the American Society of Echocardiography) and cardiac biomarkers. Blood vessels were estimated by carotid intima-media thickness, pulse wave velocity, and brachial artery flow-mediated dilatation (FMD). The examinations were performed at 28 to 79 (mean 43) months after transplantation. RESULTS: Cardiovascular risk factors were observed in all patients after transplantation: 2 had insulin-dependent diabetes, 3 developed dyslipidemia and hypertension, 2 had chronic kidney disease stage 3. Concentric left ventricular hypertrophy was found in 1 and ventricular concentric remodeling in 4 patients. Impaired diastolic function (E/e' > 8) was observed in 2 patients. The index volume of the left atrium was higher in all patients. The cardiac biomarkers N-terminal pro-brain natriuretic peptide, C-reactive protein, and troponins were within normal range. Carotid intima-media thickness was higher in 1 patient and normal in 4 patients. Arterial stiffness measured by pulse wave velocity was not increased in all patients. Native brachial artery FMD response, an index of endothelium-dependent function, was abnormal in 2 patients, but in the transplanted extremity FMD was abnormal in 4 patients. CONCLUSIONS: Pathologic changes in cardiac structures were found in all patients, but the arterial wall changes and endothelial dysfunction were observed in some patients. Patients after hand transplantation are at higher risk for cardiovascular disease.

Impact of hormonal contraception on prothrombotic activity in vessels.

One of the most common, efficient and convenient methods of contraception is hormonal contraception. Due to its popularity among young women, the safety of this method should be taken into consideration. Alternative ways of hormonal application are used and additional prothrombotic factors are being researched in order to minimize prothrombotic activity. The paper presents current data on the relationship between hormonal contraception and vascular complications based on peer-reviewed medical journals that were published between the years 2001 and 2013.

Chronic lower limb ischemia and advanced renal failure. Do we possess sufficient therapeutic knowledge?

Chronic lower limb ischemia diminishes the quality of life and is associated with a higher risk of limb amputation and cardiovascular mortality. Coexisting chronic renal disease can modulate the response to pharmacotherapy and revascularization, and thus influence prognosis. This paper reviews current literary evidence regarding therapeutic problems observed in patients with obliterative atherosclerosis and renal failure. We reviewed articles from peer-reviewed medical journals which were published between 2000 and 2011. The poorer clinical response in the discussed patients is not only connected with the direct failure of surgical and endovascular procedures, but first of all with the high mortality of the patients. There is still a lack of sufficient evidence on the effectiveness of currently used anti-atherosclerotic agents in patients with end-stage renal failure. A certain priority is the search for an effective therapeutic strategy that would reduce mortality associated with cardiovascular conditions in this particular group of patients. Identifying patients who can benefit most from costly endovascular procedures is another vital issue.

[Abdominal presentation of B-cell non-Hodgkin's lymphoma (B-NHL) - surgical treatment and its results. Report of the Polish Paediatric Leukaemia/Lymphoma Study Group]. / Manifestacja brzuszna chloniaka B-komórkowego u dzieci - interwencja chirurgiczna i wyniki leczenia. Raport PPGLBC.

The aim of this study was to analyse the effect of LMB-89 protocol and surgical procedure at initial laparotomy on the outcome in children with abdominal B-cell NHL. The initial surgery intervention was: complete resection (20% pts), subtotal resection (20%), partial resection (4%), biopsy (36%). Postoperative complications occurred in 5 children. Complete recovery (CR) was achieved in 92% pts. There were 4% non responder patients. Two patients died before CR evaluation (tumour lysis syndrome; bleeding and multi organ failure after initial surgery). One patient died in CCR from sepsis probably influenced by the previous local operation. 10.8% patients relapsed. The estimate EFS for all patients with AB-NHL is 81%, 85% for stage III and 73% for stage IV. Major surgery in advanced stages is not recommended since it delays chemotherapy and fails to improve overall survival.
