First-Line Combination with Proteasome Inhibitor-Based Treatment and Zoledronic Acid Is Effective in Reducing Later Fractures in Multiple Myeloma Irrespective of Multiple Myeloma Bone Disease at Diagnosis.

The present study provides real-world evidence on the treatment of multiple myeloma (MM) bone disease with various bisphosphonates combined for different myeloma-specific treatments as no validated data regarding the best combination treatment for bone disease associated with MM are available. We examined retrospectively 345 MM patients treated with autologous stem cell transplantation in Finland during 1996-2020. The median age of the patients was 60 years with a median follow-up time of 50 months (1-339).

Biallelic hexokinase 1 (HK1) variants causative of non-spherocytic haemolytic anaemia: A case series with emphasis on the HK1 promoter variant and literature review.

The hexokinase (HK) enzyme plays a key role in red blood cell energy production. Hereditary non-spherocytic haemolytic anaemia (HNSHA) caused by HK deficiency is a rare disorder with only 12 different disease-associated variants identified. Here, we describe the clinical features and genotypes of four previously unreported patients with hexokinase 1 (HK1)-related HNSHA, yielding two novel truncating HK1 variants.

Distinct Fatty Acid Compositions of HDL Phospholipids Are Characteristic of Metabolic Syndrome and Premature Coronary Heart Disease-Family Study.

HDL particles can be structurally modified in atherosclerotic disorders associated with low HDL cholesterol level (HDL-C). We studied whether the lipidome of the main phosphatidylcholine (PC), lysophosphatidylcholine (LPC) and sphingomyelin (SM) species of HDL2 and HDL3 subfractions is associated with premature coronary heart disease (CHD) or metabolic syndrome (MetS) in families where common low HDL-C predisposes to premature CHD. The lipidome was analyzed by LC-MS.

RVD induction and autologous stem cell transplantation followed by lenalidomide maintenance in newly diagnosed multiple myeloma: a phase 2 study of the Finnish Myeloma Group.

Autologous stem cell transplantation (ASCT) combined with novel agents is the standard treatment for transplant-eligible, newly diagnosed myeloma (NDMM) patients. Lenalidomide is approved for maintenance after ASCT until progression, although the optimal duration of maintenance is unknown. In this trial, 80 patients with NDMM received three cycles of lenalidomide, bortezomib, and dexamethasone followed by ASCT and lenalidomide maintenance until progression or toxicity.

Incidence of solid cancer in patients with follicular lymphoma.

Patients with follicular lymphoma (FL) have classically had a higher risk of solid cancers than the general population, but there is little data available in patients diagnosed and treated with modern day regimens. We conducted a retrospective multicenter study assessing the cumulative incidence of solid cancers other than nonmelanoma skin cancer in patients with FL between 1997 and 2016 and determined the standardized incidence ratio (SIR) to compare the incidence of solid cancers with that of the general population Among 1002 FL patients with 7 years of median follow-up, we found 74 solid cancers (most common breast [ = 19], lung and colon [ = 9 each]). The cumulative incidence was 3.

Risk of secondary haematological malignancies in patients with follicular lymphoma: an analysis of 1028 patients treated in the rituximab era.

Follicular lymphoma (FL) is the most common indolent lymphoma. Currently there are many comparable treatment options available for FL. When selecting the most optimal therapy it is important to consider possible late effects of the treatment as well as survival.

Altered MicroRNA Profile in Osteoporosis Caused by Impaired WNT Signaling.

Context: WNT signaling is fundamental to bone health, and its aberrant activation leads to skeletal pathologies. The heterozygous missense mutation p.C218G in WNT1, a key WNT pathway ligand, leads to severe early-onset and progressive osteoporosis with multiple peripheral and spinal fractures.

Defective WNT signaling associates with bone marrow fibrosis-a cross-sectional cohort study in a family with WNT1 osteoporosis.

Unlabelled: This study explores bone marrow function in patients with defective WNT1 signaling. Bone marrow samples showed increased reticulin and altered granulopoiesis while overall hematopoiesis was normal. Findings did not associate with severity of osteoporosis.

Impaired HDL2-mediated cholesterol efflux is associated with metabolic syndrome in families with early onset coronary heart disease and low HDL-cholesterol level.

Objective: The potential of high-density lipoproteins (HDL) to facilitate cholesterol removal from arterial foam cells is a key function of HDL. We studied whether cholesterol efflux to serum and HDL subfractions is impaired in subjects with early coronary heart disease (CHD) or metabolic syndrome (MetS) in families where a low HDL-cholesterol level (HDL-C) predisposes to early CHD.

Methods: HDL subfractions were isolated from plasma by sequential ultracentrifugation.

A randomized phase II study of stem cell mobilization with cyclophosphamide+G-CSF or G-CSF alone after lenalidomide-based induction in multiple myeloma.

The most common means of mobilizing autologous stem cells is G-CSF alone or combined with cyclophosphamide (CY) to obtain sufficient CD34+ cells for one to two transplants. There are few prospective, randomized studies investigating mobilization regimens in multiple myeloma (MM), especially after lenalidomide-based induction. We designed this prospective, randomized study to compare low-dose CY 2 g/m2 +G-CSF (arm A) and G-CSF alone (arm B) after lenalidomide-based up-front induction in MM.

Interleukin 8 promoter polymorphism predicts the initial response to bevacizumab treatment for exudative age-related macular degeneration.

Purpose: To study the association of single-nucleotide polymorphisms of interleukin 8, vascular endothelial growth factor, erythropoietin, complement factor H, complement component C3, and LOC387715 genes with the response to bevacizumab treatment in exudative age-related macular degeneration.

Methods: Clinical records, smoking history, optical coherence tomography, and angiographies of 96 bevacizumab-treated exudative age-related macular degeneration patients were analyzed retrospectively. Blood DNA was collected.

Long telomeres in blood leukocytes are associated with a high risk of ascending aortic aneurysm.

Ascending aortic aneurysm is a connective tissue disorder. Even though multiple novel gene mutations have been identified, risk profiling and diagnosis before rupture still represent a challenge. There are studies demonstrating shorter telomere lengths in the blood leukocytes of abdominal aortic aneurysm patients.

Plasma levels of antibodies against oxidized LDL are inherited but not associated with HDL-cholesterol level in families with early coronary heart disease.

Objective: Oxidized low-density lipoproteins (oxLDL) and antibodies against them (anti-oxLDLs) are thought to play a central role in atherosclerosis. One proposed antiatherosclerotic mechanism for HDL is to prevent oxidation of LDL. This study examined whether plasma HDL-cholesterol (HDL-C) is related to plasma anti-oxLDL levels.

Elevated messenger RNA expression and plasma protein levels of osteopontin and matrix metalloproteinase types 2 and 9 in patients with ascending aortic aneurysms.

Objective: Ascending aortic aneurysms result from a degenerative process in the aortic wall, characterized by the loss of smooth muscle cells and elastic fibers. We hypothesized that there would be changes in plasma protein and aortic tissue messenger RNA levels of osteopontin, matrix metalloproteinase type 2, matrix metalloproteinase type 9, and tissue inhibitor of matrix metalloproteinases type 1 in ascending aortic aneurysm samples.

Methods: Plasma, aortic tissue, and aortic mRNA samples were collected from patients with an ascending aortic aneurysm or an abdominal aortic aneurysm and from control individuals.

Low plasma antibodies specific for phosphatidylethanol in alcohol abusers and patients with alcoholic pancreatitis.

Phosphatidylethanol (PEth) is a group of alcohol-modified phospholipids present in cell membranes after heavy drinking. Our aim was to demonstrate the presence of human plasma antibodies binding to PEth and to address their specificity and value in detecting subjects engaged in heavy alcohol consumption. Antibodies to PEth were analyzed in plasma from heavy drinkers (n=20), patients with alcoholic pancreatitis (n=58) and control subjects (n=24), using chemiluminescent immunoassay.

Genetic and environmental determinants of total and high-molecular weight adiponectin in families with low HDL-cholesterol and early onset coronary heart disease.

Objective: Plasma adiponectin and high-density lipoprotein cholesterol (HDL-C) exhibit a well-known positive metabolic correlation. Neither heritability nor genome-wide linkage analysis for the high-molecular weight (HMW) adiponectin is available. This work estimates the genetic and environmental determinants and the heritabilities of the adiponectins and lipid traits in Finnish families with early onset coronary heart disease (CHD) and low HDL-C.

Separating the mechanism-based and off-target actions of cholesteryl ester transfer protein inhibitors with CETP gene polymorphisms.

Background: Cholesteryl ester transfer protein (CETP) inhibitors raise high-density lipoprotein (HDL) cholesterol, but torcetrapib, the first-in-class inhibitor tested in a large outcome trial, caused an unexpected blood pressure elevation and increased cardiovascular events. Whether the hypertensive effect resulted from CETP inhibition or an off-target action of torcetrapib has been debated. We hypothesized that common single-nucleotide polymorphisms in the CETP gene could help distinguish mechanism-based from off-target actions of CETP inhibitors to inform on the validity of CETP as a therapeutic target.

Genome scan for loci regulating HDL cholesterol levels in Finnish extended pedigrees with early coronary heart disease.

Coronary heart disease (CHD) is the leading cause of mortality in Western societies. Its risk is inversely correlated with plasma high-density lipoprotein cholesterol (HDL-C) levels, and approximately 50% of the variability in these levels is genetically determined. In this study, the aim was to carry out a whole-genome scan for the loci regulating plasma HDL-C levels in 35 well-defined Finnish extended pedigrees (375 members genotyped) with probands having low HDL-C levels and premature CHD.

Vascular endothelial growth factor gene variation and the response to photodynamic therapy in age-related macular degeneration.

Purpose: To evaluate the role of vascular endothelial growth factor (VEGF) gene polymorphisms in exudative age-related macular degeneration (AMD).

Design: Retrospective, comparative case series.

Participants: Patients with recent exudative AMD (n = 162) and age-matched subjects without AMD (n = 85).

Polymorphism of the manganese superoxide dismutase gene but not of vascular endothelial growth factor gene is a risk factor for diabetic retinopathy.

Background: In diabetic retinopathy, the vascular endothelium is damaged due to oxidative stress and inflammation, and vitreous VEGF concentration becomes elevated. The association of diabetic retinopathy with single nucleotide polymorphisms (SNPs) was studied on two genes: VEGF, an important mediator of neovascularisation, and MnSOD, a major antioxidant enzyme.

Methods: The study population was 755 individuals consisting of 131 diabetic (type 1 or type 2) patients with diabetic retinopathy (DR group), 98 diabetic controls without retinopathy (DC group) and 526 non-diabetic controls.

Clinical Candida krusei isolates remain susceptible during extensive exposure to antifungal drugs.

We have previously reported a Candida krusei outbreak during which a number of our patients were infected or colonized by several different closely related Candida krusei genotypes. The treatment response in many of our patients was at best modest and the patients remained positive for Candida krusei. We speculated that extended exposure to antifungals in patients with an incomplete treatment response might lead to the conditions for selection of drug resistance in the multiple Candida krusei clones.

Variation in the vascular endothelial growth factor gene, carotid intima-media thickness and the risk of acute myocardial infarction.

Background: Vascular endothelial growth factor (VEGF) is a potent angiogenic growth factor, but its role in atherogenesis is still unclear. Our goal was to study whether three variants of the VEGF gene, previously associated with VEGF production, are linked to atherosclerosis defined as carotid intima-media thickness (IMT) and as the risk of acute myocardial infarction (AMI).

Material And Methods: Three VEGF gene single nucleotide polymorphisms (SNPs) (-2578A>C rs699947, -634C>G rs2010963 and +936C>T rs3025039) were genotyped in 516 control subjects of the OPERA (Oulu Project Elucidating Risk of Atherosclerosis) cohort and in 251 survivors of AMI.

Effects of phosphatidylethanol on mouse adipocyte differentiation and expression of stearoyl-CoA desaturase 1.

Background: Phosphatidylethanol (PEth) is an aberrant phospholipid formed in vivo only in the presence of ethanol. In circulation PEth is associated with lipoproteins and is transferred from one lipoprotein to another. Lipoprotein-associated PEth affects endothelial and smooth muscle cells of blood vessels, but its effects on other cell types have not been explored.

Extracellular superoxide dismutase has a highly specific localization in idiopathic pulmonary fibrosis/usual interstitial pneumonia.

Aims: Recent studies suggest the importance of oxidant stress in the progression of pulmonary fibrosis. The aim of this study was to investigate extracellular superoxide dismutase (ECSOD), the major antioxidant enzyme of the extracellular matrix of human lung, in biopsy-proven idiopathic pulmonary fibrosis (IPF) related to usual interstitial pneumonia (UIP).

Methods And Results: Fibrotic areas and fibroblastic foci in UIP lungs were notable for absence of ECSOD by immunohistochemistry.
