Newly proposed diagnostic criteria for Alzheimer's disease include cerebrospinal fluid (CSF) tau levels as one core supportive criterion. The published high sensitivity and specificity figures for CSF tau levels in Alzheimer's disease are offset by the large range of proposed cutoff values (9.6 pg/mL to 1140 pg/mL). This study aimed to provide guidance on how to establish, validate and audit CSF tau cutoff values using an unbiased, two-stage multicentre strategy. Both receiver operator characteristics (ROC) optimised and population-based cutoff values were calculated on a pilot dataset (n=99), validated in a large dataset (n=560) and then compared to the literature. The data suggest using an ROC optimised cutoff level of 323 +/- 51.7 pg/mL allowing for the published inter-laboratory coefficient of variation of 16%. This cutoff level was confirmed in a prospective audit (n=100). As demand for CSF tau levels will increase globally, the accuracy of local CSF hTau cutoff levels can be compared against this benchmark. (C) 2009 Elsevier Inc. All rights reserved.

Review Ophthalmology

Clinical review of retinotopy

Jenny Nij Bijvank, Lucas Maillette de Buy Wenniger, Pim de Graaf, Axel Petzold

Summary: This review discusses Dr. Gordon T. Plant's contributions to understanding optic nerve pathology, based on two observations made almost three decades apart. Through the combination of OCT and MRI technology, it is now possible to trace axonal degeneration throughout the visual system at a high resolution, providing new opportunities for distinguishing incidental findings from sinister pathology.

Blood β-synuclein is related to amyloid PET positivity in memory clinic patients

Patrick Oeckl, Marina Bluma, Marco Bucci, Steffen Halbgebauer, Konstantinos Chiotis, Anna Sandebring-Matton, Nicholas J. Ashton, Guglielmo Di Molfetta, Lana Grotschel, Miia Kivipelto, Kaj Blennow, Henrik Zetterberg, Irina Savitcheva, Agneta Nordberg, Markus Otto

Summary: Plasma beta-synuclein levels were found to be higher in individuals with Alzheimer's disease and mild cognitive impairment with amyloid-beta positivity. It demonstrated good discrimination and prediction of amyloid-beta status. The correlation between plasma beta-synuclein and amyloid-beta PET was observed in multiple cortical regions. These findings suggest that beta-synuclein is not a direct marker of amyloid-beta pathology and highlight the different longitudinal dynamics of synaptic degeneration and amyloid deposition in Alzheimer's disease.

Higher plasma β-synuclein indicates early synaptic degeneration in Alzheimer's disease

Patrick Oeckl, Shorena Janelidze, Steffen Halbgebauer, Erik Stomrud, Sebastian Palmqvist, Markus Otto, Oskar Hansson

Summary: Beta-synuclein can serve as a synaptic blood biomarker for Alzheimer's disease, even in the preclinical stages. Higher levels of plasma beta-synuclein are observed in preclinical AD, mild cognitive impairment, and AD dementia. The levels are associated with amyloid and tau pathology, as well as cognitive impairment and temporal cortical thinning.

Summary: This study investigated the association between vitamin B12 status and biomarkers of Alzheimer's disease. The results suggest that vitamin B12-related markers are associated with AD biomarkers and cognitive performance. Vitamin B12 supplementation may be important in slowing down brain changes and cognitive decline.

Acceptability and feasibility of plasma phosphorylated-tau181 in two memory services

Jemma Hazan, Simon Hall, Alex Pemberton, Ian Sherriffs, Suzanne Joels, Amanda Heslegrave, Elena Veleva, Mamoona Ghauri, Rhiannon Laban, Emily Abel, Henrik Zetterberg, Nick C. C. Fox, Robert Howard

Summary: This study explored the utility of plasma phosphorylated-tau181 (p-tau181) as a blood-based biomarker for Alzheimer's disease pathology. The results showed that 86% of clinicians found the p-tau181 result to be helpful and 44% of cases found it useful in making the diagnosis. However, further education and training are needed for clinicians to understand and interpret ambiguity in biomarker results.

Advancing Diagnostic Certainty in Alzheimer's Disease: A Synthesis of the Diagnostic Process

Jemma Hazan, Kathy Y. Liu, Nick Fox, Robert Howard

Summary: Changes in diagnostic certainty can be evaluated by assessing the impact of a diagnostic test in driving decision making. Diagnostic tests can be appraised using validated measures of accuracy, i.e., sensitivity, specificity, and positive or negative predictive values against a known reference standard. However, other less well formalized factors affect diagnostic certainty.

High diagnostic performance of plasma and cerebrospinal fluid beta-synuclein for sporadic Creutzfeldt-Jakob disease

Samir Abu-Rumeileh, Steffen Halbgebauer, Giuseppe Mario Bentivenga, Lorenzo Barba, Simone Baiardi, Andrea Mastrangelo, Patrick Oeckl, Petra Steinacker, Angela Mammana, Sabina Capellari, Markus Otto, Piero Parchi

Summary: Beta-synuclein is a promising biomarker for synaptic damage in cerebrospinal fluid and blood, and it can accurately distinguish sporadic Creutzfeldt-Jakob disease from non-prion rapidly progressive dementias. It outperforms protein 14-3-3 and total tau in cerebrospinal fluid, and has similar diagnostic value as cerebrospinal fluid biomarkers in plasma. Beta-synuclein may serve as the first highly accurate blood biomarker for the diagnosis of sporadic Creutzfeldt-Jakob disease.

Plasma & beta;-synuclein, GFAP, and neurofilaments in patients with malignant gliomas undergoing surgical and adjuvant therapy

Samir Abu-Rumeileh, Lorenzo Barba, Matthias Bache, Steffen Halbgebauer, Patrick Oeckl, Petra Steinacker, Antje Guettler, Jacqueline Kessler, Joerg Illert, Christian Strauss, Dirk Vordermark, Markus Otto

Summary: The concentrations and prognostic roles of plasma β-synuclein, glial fibrillary acidic protein (GFAP), and neurofilament proteins (NfL and NfH) were analyzed in 33 patients with malignant gliomas. GFAP and NfL levels were higher in glioblastoma patients compared to other tumor cases. Post-surgery, β-syn, NfL, and NfH increased, while GFAP decreased in long-term follow-up. Surgery and/or radiotherapy regimens influenced β-syn and neurofilament concentrations. GFAP and neurofilament levels were significantly associated with survival. Plasma neuronal and astrocytic biomarkers are differentially altered in malignant glioma types and have distinct trajectories after surgical and adjuvant therapy.

Summary: Optical coherence tomography (OCT) is a non-invasive method that can be used to rapidly and quantitatively examine the integrity of the neuroretina. It has been shown that OCT can be used to observe retinal thinning in patients with childhood dementia, and to assess the improvement of retinal structure after treatment. Furthermore, OCT can provide insights into other childhood dementias based on the correlation between retinal and brain degeneration in Sanfilippo syndrome.

Altered T cell development in an animal model of multiple sclerosis

Qianling Jiang, Xin Ma, Gaochen Zhu, Wen Si, Lingyu He, Guan Yang

Summary: This study investigated the effects of EAE induction on thymopoiesis and T cell development, revealing changes such as increased apoptosis, decreased proliferation, and a blockade in the transition from double-negative thymocytes to double-positive cells. It was also found that positive selection was disrupted in the thymus of EAE mice, along with an increased production of regulatory T cells.

Subclinical respiratory dysfunction and impaired ventilatory adaptation in degenerative cervical myelopathy

Hannah Sweetman, Mahmudur Rahman, Aditya Vedantam, Kajana Satkunendrarajah

Summary: Degenerative cervical myelopathy (DCM) is a neurological condition characterized by chronic compression of the cervical spinal cord, leading to impaired limb function. While respiratory dysfunction is not a common symptom of DCM, it can affect the ventilatory response to respiratory challenges. Surgical decompression improves sensorimotor function in DCM, but its impact on respiratory function is unclear. This study evaluates respiratory function and adaptive ventilation in a DCM model, showing that DCM impairs acute adaptive ventilatory ability and surgical decompression does not fully restore it.

Summary: This study found that Osteopontin (OPN) can attenuate inflammatory responses after subarachnoid hemorrhage (SAH) by promoting an anti-inflammatory microglial state. This effect may be mediated through the integrin-FAK-STAT3 and NF-kappa B signaling pathways.
