Among various albumin posttranslational modifications (PTMs), N- and C-terminal truncations (HSA-DA and HSA-L) have also shown biomarker potential in disease states. We examined albumin truncation longitudinal trends and correlations during diabetes therapy toward possible future clinical applications. In a preliminary longitudinal therapy investigation, mass spectrometry was employed to track PTMs of human serum albumin (HSA), including glycation (GA), cysteinylation (CA or HNA1; reversible), di/trioxidation (OA or HNA2; irreversible), and truncation (TA).

Introduction Primary aldosteronism (PA), once considered rare, is now recognized as the most common cause of secondary hypertension, accounting for almost a quarter of resistant hypertension (RH) cases. Despite this, PA remains underdiagnosed, with an extremely low percentage of RH patients undergoing screening. Methods In a specialty diabetes-endocrinology clinic, the aldosterone:renin ratio (ARR) was assessed in 115 consecutive RH patients (ages 21-93 years; 47% male; 87% with type 2 diabetes).

Article Synopsis
  • - The study investigates how glycation affects human serum albumin (HSA), which is altered by the formation of advanced glycation end products (AGEs), using advanced techniques like liquid chromatography-tandem mass spectrometry (LC-MS/MS) to map glycation sites.
  • - Researchers analyzed samples from healthy individuals to severe diabetic patients and discovered a range of glycated albumin levels (GA), revealing that isolation techniques improved identification of glycation sites compared to direct digestion of whole serum.
  • - The study tested different enzymes, finding that trypsin was more effective than Glu-C for analyzing glycation patterns, which helped pinpoint specific sites on HSA that are most affected by increased glycation levels.

Background And Aims: The study sought to compare the efficacy of endoscopic injection sclerotherapy with cyanoacrylate glue (EIS-CYA) vs EIS-CYA plus a radiologic intervention (RI) (either transjugular intrahepatic portosystemic shunt or balloon-occluded retrograde transvenous obliteration) for secondary prophylaxis in patients with liver cirrhosis who presented with acute variceal bleeding from cardiofundal varices. Primary outcome measure was gastric varix (GV) rebleed rates at 1 year.

Methods: Consecutive cirrhosis patients with acute variceal bleeding from cardiofundal varices were randomized into 2 arms (45 in each) after primary hemostasis by EIS-CYA.

Purpose: To determine the rate of platelet transfusion in patients with cirrhosis and severe thrombocytopenia (platelet counts <50 × 10/L) undergoing high-risk invasive procedures when prescribed by thromboelastography (TEG) compared with empirical and on-demand transfusion strategies.

Materials And Methods: This was a single-center, single-blinded, randomized controlled trial. Patients with cirrhosis and severe thrombocytopenia undergoing high-risk invasive procedures were randomized into 3 groups: TEG group, transfusions based on TEG parameters; standard of care (SOC) group, 3 units of random donor platelets before procedure; and on-demand group, transfusions based on procedural adverse events/clinician's discretion.

Article Synopsis
  • A study was conducted to evaluate the effectiveness of intravenous albumin infusions in patients with acute severe ulcerative colitis (ASUC) who were not responding to standard steroids.
  • The trial involved 61 patients, who were divided into two groups: one receiving albumin with standard care and exclusive enteral nutrition, and the other receiving only standard care and nutrition.
  • Results showed no significant difference in steroid response, need for colectomy, or adverse events between the two groups, indicating that albumin infusion did not provide additional benefits for ASUC patients.

Rapid identification of microbial pathogens "directly" from positive blood cultures (PBCs) is critical for prompt initiation of empirical antibiotic therapy and clinical outcomes. Towards higher microbial identification rates, we modified a published initial serum separator tubes-based MALDI-TOF-MS protocol, for blood culture specimens received at a non-hospital based standalone diagnostic laboratory, Bangalore, India: (a) "Initial" protocol #1: From 28 PBCs, identification= 39% (Gram-negative= 43%: Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa; Gram-positive: 36%: Enterococcus faecalis, Staphylococcus aureus, Staphylococcus haemolyticus); mis-identification= 14%; non-identification= 47%. (b) "Modified" protocol #2: Quality controls (ATCC colonies spiked in negative blood cultures) From 7 analysis, identification= 100% (Escherichia coli, Klebsiella pneumonia, Klebsiella oxytoca, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus); From 7 PBCs, identification= 57%; mis-identification= 14%; non-identification= 29%.

Cys34 albumin redox modifications (reversible "cysteinylation" and irreversible "di/trioxidation"), besides being just oxidative stress biomarkers, may have primary pathogenetic roles to initiate and/or aggravate cell, tissue, and vascular damage in diabetes. In an exploratory "proof-of-concept" pilot study, we examined longitudinal changes in albumin oxidation during diabetes therapy. Mass spectrometric analysis was utilized to monitor changes in human serum albumin (HSA) post-translational modifications {glycation [glycated albumin (GA)], cysteinylation [cysteinylated albumin (CA) or human non-mercaptalbumin-1; reversible], di/trioxidation (di/trioxidized albumin or human non-mercaptalbumin-2; irreversible), and truncation (truncated albumin)} during ongoing therapy.

Hemangiomatosis of the spleen is a benign vascular condition occurring as a manifestation of systemic angiomatosis. It is usually associated with Klippel-Trenaunay syndrome (KTS), which is a rare congenital malformation characterized by a triad of varicose veins, bony and soft tissue hypertrophy, and cutaneous and visceral hemangiomas and/or venous malformations. The association of splenic hemangiomatosis with KTS is less documented in the literature.

Albumin, the most abundant and physiologically vital serum protein, accumulates a range of chemical modifications, as consequence of encounters with large number of reactive molecules whose concentrations increase in serum under pathological conditions. In a "proof of concept" study, mass spectrometric analysis was utilized to quantitate albumin post-translational modifications (glycation, oxidation, and truncation; individual isoforms and total) in four informative subject groups [type 1 diabetes (T1DM), type 2 diabetes (T2DM), prediabetes-obesity and healthy; all with estimated glomerular filtration rate ≥60 mL/(min·m)]. Besides glycated albumin (GA/mass spectrometry), glycated serum protein (GSP/nitro blue tetrazolium colorimetry), and glycated hemoglobin (HbA1c/high-performance liquid chromatography) were also measured.
