Background An increased incidence of thromboembolic events (TE) are reported in nephrotic syndrome (NS) leading to recommendations for prophylactic anticoagulation (PAC). However, as no randomized clinical trial has established the efficacy or risks associated with PAC, guidelines are empiric or substantiated only by estimates of risks and benefits. This study evaluates the risk of TE and hemorrhagic complications in patients with NS treated with PAC and compares to patients not receiving PAC. Methods We included patients diagnosed with NS from two Danish nephrology departments with different practices for the use of PAC. Patients were included if presenting with NS from September 2006 to January 2012, a P-albumin < 30 g/L, and renal biopsy confirming non-diabetic, glomerular disease. Patients aged < 16 years, on renal replacement therapy, or administered anticoagulants at the onset of NS were excluded. Bleeding episodes and/or TE were identified from patient records. Bleeding episodes were divided into minor and major bleeding. Results Of the 79 patients included, 44 patients received PAC either as low or high dose low-molecular-weight heparin (LMWH) or as warfarin with or without LMWH as bridging, while 35 did not receive PAC. P-albumin was significant lower in the PAC group compared to those not receiving PAC. Significantly more TEs was observed in the non-PAC group compared to the PAC group (4 versus 0 episodes, P = 0.035). The TEs observed included one patient with pulmonary embolism (PE), one with PE and deep vein thrombosis, one with PE and renal vein thrombosis, and one with a stroke. Five patients with bleeding episodes were identified among those receiving PAC, of which two were major and three were minor, while two patients in the non-PAC group experienced a minor bleeding episode ( P = 0.45 between groups). The major bleeding episodes only occurred in patients receiving PAC in combination with low dose aspirin. Conclusions In patients with NS the use of PAC was associated with a decreased risk of clinically significant TE, but may also be associated with more bleeding episodes although not statistically significant. Only patients treated with PAC in combination with anti-platelet therapy had major bleeding episodes.

We wanted to test the hypothesis that treatment with amiloride or spironolactone reduced ambulatory (ABP) and central blood pressure (CBP) and that tubular transport via ENaCγ and AQP2 was increased after furosemide treatment. During baseline conditions, there were no differences in ABP, CBP, renal tubular function, or plasma concentrations of vasoactive hormones. After furosemide treatment, an increase in CBP, CH(2)o, FE(Na), FE(K), u-AQP2/min, u-ENaCγ/min, PRC, p-Ang II, and p-Aldo was observed. The increases in water and sodium absorption via AQP2 and ENaC after furosemide treatment most likely are compensatory phenomena to antagonize water and sodium depletion.

Introduction. Small intestinal neuroendocrine tumours (NETs) have increased in incidence during the past decades. In recent years, new promising treatment modalities have been introduced. The aim of the present study was to characterize and compare patients with small intestinal NET seen in the periods 1994–2003 (group 1) and 2004–2011 (group 2) to demonstrate changes in incidence and survival in the two time periods. Patients and Methods. There were 52 NET patients in group 1 and 109 patients in group 2. Results. The incidence of small intestinal NET was 0.3/100.000/year in period 1 and 0.7/100.000/year in period 2. There was no difference in median chromogranin A levels (8709 versus 2381 pmol/L, P = 0.107), presence of liver metastases (56% versus 44%), clinical symptoms (flushing/diarrhea), or Ki67 index (2% versus 2%), between the two time periods. The 5-year survival rate in the two time periods was similar, 64.7%, and 77.0%, respectively, (P = 0.23). Conclusion. We observed an increase in the incidence of small intestinal NET during the period from January 1994 to December 2011, but we were not able to demonstrate an improved survival during the same time period.
