Serum thrombin activatable fibrinolysis inhibitor levels in patients with newly diagnosed multiple myeloma.

Multiple myeloma has been associated with the development of thromboembolic events. Thrombin activatable fibrinolysis inhibitor (TAFI) is a carboxypeptidase B-like proenzyme, which potently inhibits fibrinolysis. The purpose of the present study was to assess the TAFI levels in patients with newly diagnosed multiple myeloma. Twenty-seven newly diagnosed multiple myeloma patients (16 women and 11 men) and 27 age-matched healthy individuals (14 women and 13 men) were included in the study. Serum TAFI levels were significantly increased in patients with multiple myeloma (46 ± 13. 3 vs. 36. 6 ± 9.7 µg/ml) compared with healthy individuals. Serum TAFI levels were negatively correlated with serum albumin (CC: -0.453, P < 0.05) and hemoglobin levels (CC: -0.392, P < 0.05) and positively correlated with the ß-2 microglobulin levels (CC: 0.524, P < 0.05). In this study, we observed significantly elevated TAFI levels in patients with multiple myeloma and higher serum TAFI levels were suggested to be associated with higher disease stage. With these results, a possible role of elevated TAFI levels in thromboembolic manifestations in the course of multiple myeloma can be suggested.

Serum BNP concentration and left ventricular mass in CAPD and automated peritoneal dialysis patients.

OBJECTIVE: To compare ultrafiltration under continuous ambulatory peritoneal dialysis (CAPD) and automated PD (APD), disclosing potential effects on serum B-type natriuretic peptide (BNP) levels and echocardiographic findings. PATIENTS AND METHODS: This cross-sectional clinical study included 32 patients on CAPD and 30 patients on APD without clinical evidence of heart failure or hemodynamically significant valvular heart disease. Peritoneal equilibration tests, BNP levels, and echocardiographic measurements were performed in each subject. BNP measurements were also performed in 24 healthy control subjects. RESULTS: Patients on APD had lower ultrafiltration and higher values of BNP and left ventricular mass index (LVMI) compared with patients on CAPD (respectively: 775 +/- 160 vs 850 +/- 265 mL, p = 0.01; 253.23 +/- 81.64 vs 109.42 +/- 25.63 pg/mL, p = 0.001; 185.12 +/- 63.50 vs 129.30 +/- 40.95 g/m(2), p = 0.001). This occurred despite higher mean dialysate glucose concentrations and far more extensive use of icodextrin in the APD group. CONCLUSION: Treatment with APD is associated with higher plasma BNP levels and LVMI compared to CAPD. This may be the result of chronic fluid retention caused by lower ultrafiltration in APD patients.

Active pulmonary tuberculosis with vertebra and rib involvement: case report.

Multifocal skeletal tuberculosis is defined as osteoarticular lesions that occur simultaneously at two or more locations and is generally associated with disseminated disease. Although involvement of bones accounts for 1 to 5% of all tuberculosis cases, multifocal involvement of the skeleton is extremely rare. We present a case of active pulmonary tuberculosis (TB) with vertebral and rib involvement and multiple hypodense lytic lesions accompanied by a paravertebral mass lesion. In the differential diagnosis, metastases, lymphoma, multiple myeloma, chordoma sarcoidosis and rare spinal infections such as brucellosis and fungal disease were considered. The diagnosis was established by surgical biopsy, taken by video-assisted thoracoscopic surgery. Especially for patients from TB-endemic areas, tuberculosis must be considered in the differential diagnosis and treatment should be started without delay.
