Glycosylated ferritin

Protein self-assembling nanoparticles (NPs) can be used as carriers for antigen delivery to increase vaccine immunogenicity. NPs mimic the majority of invading pathogens, inducing a robust adaptive immune response and long-lasting protective immunity. In this context, we investigated the potential of NPs of different sizes and shapes-ring-, rod-like, and spherical particles-as carriers for bacterial oligosaccharides by evaluating in murine models the role of these parameters on the immune response. Oligosaccharides from Neisseria meningitidis type W capsular polysaccharide were conjugated to ring-shape or nanotubes of engineered Pseudomonas aeruginosa Hemolysin-corregulated protein 1 (Hcp1cc) and to spherical Helicobacter pylori ferritin...

Congenital disorder of glycosylation type Ia (CDG-Ia) is an autosomal recessive genetic disease caused by a mutation in the phosphomannomutase 2 (PMM2) gene. We have identified a 13-month-old boy who has been diagnosed with CDG-Ia. He displays several characteristic symptoms, including cerebellar hypoplasia, severe developmental retardation, hypothyroidism, impaired liver function, and abnormal serum ferritin levels. Through whole-exome sequencing, we discovered novel complex heterozygous mutations in the PMM2 gene, specifically the c...

Previous evidence has shown an association between serum ferritin and bilirubin levels in the development of type 2 diabetes mellitus (T2DM) and glycemic control. However, the evidence is scarce in Saudi Arabia. In this study, we aimed to evaluate the association between serum ferritin and bilirubin levels with glycemic control in patients with T2DM. This was a cross-sectional study that involved 153 patients with T2DM recruited from outpatient diabetes clinics. Participants were categorized into two groups: well-controlled and uncontrolled T2DM, based on their glycemic status...

The Ebola virus causes hemorrhagic fever in humans and poses a significant threat to global public health. Although two viral vector vaccines have been approved to prevent Ebola virus disease, they are distributed in the limited ring vaccination setting and only indicated for prevention of infection from orthoebolavirus zairense (EBOV)-one of three orthoebolavirus species that have caused previous outbreaks. Ebola virus glycoprotein GP mediates viral infection and serves as the primary target of neutralizing antibodies...

BACKGROUND: Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disorder that is characterized by quotidian fevers, arthritis, and an evanescent rash. Occurrence of concurrent thrombotic microangiopathy (TMA) in AOSD is rare. The treatment aspects of TMA in AOSD are actively being debated. METHODS: Medline search using MeSH terms and snowballing yielded a total of 29 articles with co-occurrence of AOSD and thrombotic thrombocytopenic purpura (TTP) including our own...

AIM: Although a low-calorie diet with lipid restriction is recommended in clinical practice guidelines for nonalcoholic fatty liver disease (NAFLD), both compliance and adherence are poor. The present study aimed to evaluate the compliance, adherence, and effectiveness of a moderate-carbohydrate diet without caloric or lipid restrictions. METHODS: Participants comprised 300 patients with NAFLD with elevated ALT levels who received counseling in carbohydrate restriction (150-200 g/day)...

BACKGROUND: Iron metabolism dysregulation may play a role in organ failure observed in Coronavirus disease 2019 (COVID-19). This study aimed to explore the whole iron metabolism in hospitalized COVID-19 patients and evaluate the impact of tocilizumab. METHODS: We performed an observational multicentric cohort study, including patients with PCR-provenCOVID-19 from the intensive care unit (ICU) (n = 66) and medical ward (n = 38). We measured serum interleukin-6 (IL-6), ferritin, glycosylated ferritin (GF), transferrin, iron, and hepcidin...

Invasive pulmonary aspergillosis is a severe fungal infection that primarily affects immunocompromised patients and is associated with high mortality. Contemporary clinical characteristics of invasive pulmonary aspergillosis and "real world" estimates and predictors of associated mortality are inadequate. TriNetX, a global research network, was queried to identify adult patients with invasive pulmonary aspergillosis diagnosis based on the ICD-10 code B44.0. We performed a propensity score-matched analysis comparing clinical characteristics among patients who survived versus non-survivors at one year...

AIM: We aimed to evaluate associations between serum ferritin and transferrin and variables related to the metabolic syndrome (MetS) in children. METHODS: Cross-sectional and longitudinal study in prepubertal children(n=832) aged 3-14 years. A subset(n=203) were re-examined after a mean follow-up of 3.7±0.8 years[range 2-6]. Outcomes were MetS and MetS components scores, glycosylated haemoglobin (HbA1c), and their follow-up change. RESULTS: Children with low ferritin had increased HbA1c Z scores (ANCOVA,P=0...

This study was designed to fully investigate the related risk factors for decreased BMD in schizophrenia, as well as evaluate the gender difference of BMD. METHOD: The BMD of the forearm of 211 patients (males/females = 140/71) who met the diagnostic criteria for DSM-5 schizophrenia was measured by dual-energy X-ray absorptiometry...

BACKGROUND: The potential effects of time factor and albuminuria on the morbid alterations in patients with type 2 diabetes (T2D) and COVID-19 are still unclear. We aimed to address the morbid alterations and the potential effects of time factor and albuminuria on the patients' characteristics before, during, and 1 year after COVID-19 recovery. METHODS: 83 patients with T2D were included, at Mansoura University Hospital, Egypt (July 2021-December 2021). Data of detailed history, physical examination, laboratory tests were recruited from files of the patients...

PURPOSE: The second wave of coronavirus disease 2019 (COVID-19) pandemic triggered a mucormycosis epidemic in India. Diabetes mellitus and dysregulated immune response were contributors, and rhino-orbital-cerebral mucormycosis (ROCM) was the most common presentation. It is however not known whether bio-chemical parameters at presentation correlate with stage of ROCM or final outcome in terms of vision or mortality. METHODS: This retrospective, hospital-based study included all in-patients of mucormycosis with ophthalmic manifestations at presentation admitted during June 1, 2021 to August 31, 2021...

The ability of isolated surface layer proteins (SLPs) to reassemble on suitable surfaces enables the application of SLPs in various fields of nanotechnology. In this work, SLPs from Lactobacillus buchneri BNCC 187,964 and L. kefir BNCC 190,565 were extracted and verified as glycosylated proteins. They were applied to coat on the surface of cationic liposomes. The absorption of the two SLPs on liposomes induced the zeta potential reduction and particle size increase. The two kinds of SLP-coated liposomes demonstrated better thermal, light and pH stability than the control liposomes...

As we already reported, fibrinogen fucosylation emerged as a prognostic marker of peritoneal membrane function in end-stage renal disease (ESRD) patients on peritoneal dialysis. After a follow-up period of 18 months, we estimated the ability of employed lectins, as well as other biochemical parameters, to serve as mortality predictors in these patients. Following a univariate Cox regression analysis, ferritin, urea clearance, residual diuresis, hyperglycemia, and an increase in the signal intensity obtained with Galanthus nivalis lectin (GNL) emerged as potential mortality predictors, but additional multivariate Cox regression analysis pointed only to glucose concentration and GNL as mortality predictors...

Adult-onset Still's disease (AOSD) is a systemic inflammatory disorder with an unknown cause characterized by high-spiking fever, lymphadenopathy, hepatosplenomegaly, hyperferritinemia, and leukocytosis. The clinical course can be divided into three significant patterns, each with a different prognosis: Self-limited or monophasic, intermittent or polycyclic systemic, and chronic articular. Two criteria sets have been validated. The Yamaguchi criteria are the most generally used, although the Fautrel criteria offer the benefit of adding ferritin and glycosylated ferritin values...

Hemophagocytic lymphohistiocytosis is a hyperinflammatory syndrome characterized by uncontrolled activation of immune cells and mediators. Two diagnostic tools are widely used in clinical practice: the HLH-2004 criteria and the Hscore. Despite their good diagnostic performance, these scores were constructed after a selection of variables based on expert consensus. We propose here a machine learning approach to build a classification model for HLH in a cohort of patients selected by glycosylated ferritin dosage in our tertiary center in Lyon, France...
