Peritoneal protein loss is one of the inevitable consequences during continuous ambulatory peritoneal dialysis (CAPD). Our objective was to study the effect of sulodexide on the protein loss and efficiency of dialysis. This study included six patients receiving CAPD treated with sulodexide at the dose of 600 IU/day given by intraperitoneal injection for 10 days. Clinical and biologic parameters were assessed before starting the treatment (D0 and after 10 days of treatment (D10. We also evaluated the benefit of therapy persisting 20 days after the end of treatment (D30...

The lymph node is a structurally complex organ of the immune system, whose dynamic cellular arrangements are thought to control much of human health. Currently, no methods exist to precisely stimulate substructures within the lymph node or analyze local stimulus-response behaviors, making it difficult to rationally design therapies for inflammatory disease. Here we describe a novel integration of live lymph node slices with a microfluidic system for local stimulation. Slices maintained the cellular organization of the lymph node while making its core experimentally accessible...

Protein losing enteropathy (PLE) refers to excessive intestinal protein loss, resulting in hypoalbuminemia. Underlying pathologies include conditions leading to either reduced intestinal barrier or lymphatic congestion. We describe the case of a patient with long-lasting diffuse abdominal problems and PLE. Repetitive endoscopies were normal with only minimal lymphangiectasia in biopsies. Further evaluations revealed an indolent marginal zone lymphoma with minor bone marrow infiltration. Monotherapy with rituximab decreased bone marrow infiltration of the lymphoma but did not relieve PLE...

We present a case of a Jehovah's Witness patient who refused blood products, with the exception of albumin and clotting factors, and underwent cesarean section under spinal anesthesia complicated by postpartum hemorrhage. She was fluid resuscitated and treated with multiple uterotonics and internal iliac artery embolization. Because of agitation she required emergency tracheal intubation. Her hemoglobin concentration dropped from a preoperative value of 12mg/dL to 3mg/dL on postoperative day one. She was acidotic, requiring vasopressors for hemodynamic stability and remained ventilated and sedated...

Danhong injection (DHI) is a widely used Chinese medicine injection (CMI) for the clinical treatment of cardiovascular and cerebrovascular diseases. In this study, a simple and efficient in vitro method based on ultrafiltration LC-MS and molecular modeling has been developed to study the human serum albumin (HSA) binding of the compounds in DHI. Seven major components including protocatechuic aldehyde, p-coumaric acid, salvianolic acid D, rosmarinic acid, salvianolic acid E, lithospermic acid and salvianolic acid B were identified as HSA ligands and their binding degrees in the proposed non-saturated model were 26...

Ascites related to metastatic colorectal cancer (mCRC) reduces patient survival and quality of life, and systemic chemotherapy is largely ineffective for managing ascites. Here, we examined the clinical efficacy of intraperitoneal (IP) ziv-aflibercept for managing refractory ascites in 15 mCRC patients who did not respond to standard chemotherapy. Fifty or 100 mg of ziv-aflibercept in 100 mL of saline solution were infused through a pigtail catheter and retained for 24 h. When the ascites drainage volumes were subsequently monitored, 73...

Advanced stage leiomyosarcoma (LMS) is incurable with current systemic antitumor therapies. Therefore, there is clinical interest in exploring novel therapeutic regimens to treat LMS. We reviewed the medical records of 75 consecutive patients with histologically confirmed metastatic LMS, who had been referred to the Clinical Center for Targeted Therapy at MD Anderson Cancer Center. To lay the foundation for potential phase I trials for the treatment of advanced LMS, we analyzed tumor response and survival outcome data...

Specific detection of protein biomarkers plays an important role in diagnostics and therapeutics. We have fabricated polymeric nanogels, which can specifically interact with the cancer biomarker thrombin to serve as a model. Two types of 2-methacryloyloxyethyl phosphorylcholine (MPC) copolymers bearing a thrombin-binding oligonucleotide aptamer and its complementary chain were independently synthesized by redox-initiated radical polymerization. These MPC polymers associate in a complimentary fashion due to double strand formation of the oligonucleotides in aqueous media, leading to the spontaneous formation of spherical nanogels...

Heart failure patients who undergo cardiac surgery are exposed to significant perioperative complications and high mortality. We herein review the literature concerning preoperative optimization of these patients. Salient findings are that end-organ dysfunction and medication should be optimized before surgery. Specifically: (1) reversible causes of anemia should be treated and a preoperative hemoglobin level of 100 g/L obtained; (2) renal function and volume status should be optimized; (3) liver function must be carefully evaluated; (4) nutritional status should be assessed and cachexia treated to achieve a preoperative albumin level of at least 30 g/L and a body mass index > 20; and (5) medication adjustments performed, such as withholding inhibitors of the renin-angiotensin-aldosterone system before surgery and continuing, but not starting, β-blockers...

REVIEW
Xingxing S Cheng, Jane C Tan, W Ray Kim
Renal failure is a late consequence of end-stage liver disease (ESLD). Even with liver transplantation, pretransplant renal impairment remains a strong predictor of posttransplant mortality. This review seeks to summarize and critically appraise common therapies used in this setting, including pharmacologic agents, procedures (transjugular intrahepatic portosystemic shunt, renal replacement therapy), and simultaneous liver-kidney transplantation. More experimental extracorporal modalities, eg, albumin dialysis or bioartificial livers, will not be discussed...

Cytotoxic chemotherapeutic agents are used as the standard therapy for a range of significant cancers, but many of these drugs suffer from poor water solubility and low selectivity, limiting their clinical efficacy. To overcome these shortcomings, Cellax™ drug delivery platform was developed. Cellax™ is a polymer-based nanoparticle drug delivery system designed to solubilize hydrophobic drugs and target them to solid tumors, thereby enhancing the efficacy and reducing the side effects. Cellax-docetaxel (Cellax-DTX) displayed improved pharmacokinetic, safety, and efficacy profiles compared to native DTX (Taxotere®) and Nab-paclitaxel (Nab-PTX, Abraxane®) in multiple animal models...

BACKGROUND: Not all patients respond equally to neoadjuvant chemoradiotherapy (nCRT), with subsequent effects on survival. The systemic inflammatory response has been shown to predict long-term outcomes in colorectal cancer. The current study examined the association between systemic inflammation and nCRT in patients with rectal cancer. METHODS: Between 1999 and 2010, patients who underwent nCRT were identified. Serum measurements of hemoglobin, C-reactive protein, albumin, modified Glasgow prognostic score (mGPS), and differential white cell counts were obtained before and after nCRT...

Hyperhomocysteinemia (hHcys) is an important independent risk factor for the development of cardiovascular disease and end-stage renal disease. Although multiple approaches lowering the levels of homocysteine have been used in experimental studies and clinical trials, there is no effective therapy available to fully prevent homocysteine-induced injury. Therefore, identifying key molecules in the pathogenic pathways may provide clues to develop new therapeutic strategies for the treatment of hHcys-associated injury beyond lowering the plasma homocysteine levels...

Human serum albumin (HSA) is the main plasma protein responsible for a distribution of drugs in the human circulatory system. The binding to HSA is one of the factors that determines both the pharmacological actions and the side effects of drugs. The derivative of heme, protoporphyrin IX (PpIX), is a hydrophobic photosensitizer widely used in photodynamic diagnosis and therapy of various malignant disorders. Using absorption and fluorescence spectroscopy, it has been demonstrated that PpIX forms complexes with HSA...

Albumin is a major plasma protein that has become ubiquitous in regenerative medicine research. As such, many studies have examined its structure and advantageous properties. However, a systematic and comprehensive understanding of albumin's role, capabilities and therapeutic potential still eludes the field. In the present work, we review how albumin is applied in tissue engineering, including cell culture and storage, in vitro fertilization and transplantation. Furthermore, we discuss how albumin's physiological role extends beyond a carrier for metal ions, fatty acids, pharmacons and growth factors...
