- BACKGROUND: Beta amyloid (Abeta) protein accumulates in the brains of individuals with Alzheimer disease (AD) and is detectable in cerebrospinal fluid and plasma. OBJECTIVE: To examine plasma levels of Abeta peptides Abeta(40) and Abeta(42) as predictors of incident AD and other types of dementia. DESIGN: Prospective, population-based cohort study. SETTING: The Uppsala Longitudinal Study of Adult Men. PARTICIPANTS: Plasma Abeta(40) and Abeta(42) levels were analyzed as predictors of incident AD in 1045 men at age 70 years and 680 men at age 77 years using Cox proportional hazards analyses. Alzheimer disease and other types of dementia were diagnosed by standardized screening, clinical evaluation, and medical record review. MAIN OUTCOME MEASURES: Hazard ratios of AD (primary outcome) and vascular dementia or other dementia (secondary outcomes) according to baseline levels of plasma Abeta(40) and Abeta(42). RESULTS: From the age of 77 years at baseline, 46 individuals developed AD at follow-up (median, 5.3 years). A low plasma Abeta(40) level at age 77 years was associated with higher incidence of AD. The multivariate-adjusted hazard ratio was 4.87 (95% confidence interval, 1.63-14.6) for the lowest Abeta(40) tertile compared with the highest tertile. On follow-up from age 70 years at baseline (median, 11.2 years), 82 individuals developed AD. Plasma Abeta(40) and Abeta(42) levels measured at age 70 years were not significantly associated with incident AD. CONCLUSIONS: Low plasma Abeta(40) levels predicted incident AD in elderly men independently of potential confounders. Plasma Abeta(42) levels were not significantly associated with AD incidence. The clinical value of Abeta measurement in plasma remains to be established in future studies.

- AIMS/HYPOTHESIS: Accumulating evidence suggests that diabetes increases the risk of dementia, but few studies have addressed possible mechanisms underlying this relationship. The aim of our study was to investigate the longitudinal association of glucose metabolism, insulin secretion and insulin action with the development of Alzheimer's disease and vascular dementia. METHODS: The Uppsala Longitudinal Study of Adult Men is an ongoing observational study in Sweden in which 1,125 men aged 71 years and free from dementia underwent an OGTT and a euglycaemic insulin clamp between 1990 and 1995. During a median follow-up of 12 years, 257 persons developed dementia or cognitive impairment, of whom 81 had Alzheimer's disease and 26 vascular dementia. Associations were analysed with the Cox proportional hazards method. RESULTS: Low early insulin response to oral glucose challenge, but not low insulin sensitivity, was associated with a higher risk of Alzheimer's disease (HR for 1 SD decrease 1.32; 95% CI 1.02, 1.69) after adjustment for diabetes, blood pressure, body mass index, cholesterol, smoking and educational level. Low insulin sensitivity was associated with a higher risk of vascular dementia (HR for 1 SD decrease 1.55; 95% CI 1.02, 2.35), but not after multiple adjustments. Diabetes increased the risk of any dementia and cognitive impairment by 63%. CONCLUSIONS/INTERPRETATION: In this community-based study, low early insulin response was associated with increased risk of subsequent Alzheimer's disease, whereas low insulin sensitivity was not. Vascular dementia was not related to early insulin response. We suggest that glucometabolic disturbances are linked differentially to the pathogenesis of these two main dementia subtypes.

Amyloid β-protein, Cystatin C and Cathepsin B as Biomarkers of Alzheimer's Disease
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It is suggested that Alzheimer’s disease (AD) is caused by an imbalance between production, degradation and clearance of the amyloid-β (Aβ) protein. This imbalance leads to aggregation of Aβ and tau proteins and neurodegeneration in the brain. Today there is increasing evidence that the balance between the protease cathepsin B and the protease inhibitor cystatin C affects the tendency for Aβ to aggregate. The primary aim of this thesis was to investigate Aβ, cystatin C and cathepsin B levels in blood and cerebro-spinal fluid (CSF) in relation to the risk of AD.Studies I & II were based on the re-examinations of participants, at ages 70 and 77, in the Uppsala Longitudinal Study of Adult Men (ULSAM), a community-based prospective study initiated in 1970 (participants then being 50 years of age). In ULSAM, low plasma Aβ1-40 (Study I) and low serum cystatin C levels (Study II) were associated with a higher risk of AD. Studies III & IV were based on a cross-sectional sample of people with AD, mild cognitive impairment and healthy controls, recruited at three Swedish Memory Disorder units: Uppsala University Hospital, Uppsala, Skåne University Hospital, Malmö, and Karolinska University Hospital, Huddinge, Stockholm. In Study III, CSF cystatin C levels were positively correlated with both Aβ1-42 and tau levels. In Study IV, individuals with AD had higher mean plasma cathepsin B levels than healthy controls.In conclusion, low plasma Aβ1-40 and low serum cystatin C levels may precede clinically manifest AD in elderly men, cystatin C levels are positively correlated with Aβ1-42 and tau levels in CSF, and mean plasma cathepsin B levels are higher in people with AD compared to healthy controls. In addition to Aβ1-42 and tau levels in CSF, Aβ1-40, cystatin C and cathepsin B levels in blood may reflect the risk of AD.

Tidskriftsartikel (refereegranskat)abstract
- Cystatin C is suggested to be involved in neurodegeneration and the development of Alzheimer's disease (AD) by binding to soluble amyloid-beta (Abeta) peptides. Studies of cystatin C levels in cerebrospinal fluid (CSF) in relation to risk of AD are conflicting and relations between cystatin C, Abeta42, and tau levels in CSF in AD, mild cognitive impairment (MCI), and healthy controls are unknown. The objective of this study was to investigate cystatin C, Abeta42, and tau levels in CSF in AD, MCI, and controls. As a secondary aim, the relationships between cystatin C, Abeta42, and tau levels across disease groups were investigated. Cystatin C, Abeta42, total tau, and phosphorylated tau levels in CSF were analyzed by turbidimetry (cystatin C) and xMAP Luminex technology (Abeta and tau) in persons with AD (n=101), MCI (n=84), and healthy control subjects (n=28). Mean cystatin C levels were similar in cases of AD (5.6 mumol/L +/- 1.7), MCI (5.4 mumol/L +/- 1.48), and controls (5.6 mumol/L +/- 1.6). However, CSF cystatin C levels were strongly and positively correlated with total tau and phosphorylated tau levels (r=0.61-0.81, p< 0.0001) and Abeta42 (r=0.35-0.65, p< 0.001) independent of age, gender, and APOE genotype. Mean CSF cystatin C levels did not differ between patients with AD and MCI and healthy controls. Interestingly, cystatin C levels were positively correlated with both tau and Abeta42 levels in CSF independent of age, gender, and APOE genotype.

Tidskriftsartikel (refereegranskat)abstract
- Cathepsin B is suggested to be involved in amyloid-β (Aβ) processing and Alzheimer's disease (AD). Studies of cathepsin B levels in plasma and cerebrospinal fluid (CSF) have not been previously performed. We examined cathepsin B levels in plasma and CSF samples in persons with AD, mild cognitive impairment (MCI), and healthy controls in order to test the hypothesis that cathepsin B levels can discriminate persons with AD or MCI from healthy controls. Cathepsin B, Cystatin C, Aβ1-40 and Aβ1-42, total tau, phosphorylated tau, and albumin levels in plasma and CSF were analyzed by ELISA (Cathepsin B) turbidimetry (cystatin C), xMAP Luminex technology (Aβ1-40 and Aβ1-42 and tau), and Cobas C501 analyzer (albumin) in persons with AD (n=101), MCI (n=84), and healthy control subjects (n=28). Plasma cathepsin B levels were higher in persons with AD compared to healthy controls, both in unadjusted models and in multivariable models adjusting for age, gender, APOE genotype, cystatin C, and albumin levels: Odds ratio (OR) for AD per 1 SD of plasma cathepsin B; 2.04, 95% confidence interval (CI); 1.01-4.14, p= 0.05. There was no difference between diagnostic groups in cathepsin B levels in CSF: OR for AD per 1 SD of CSF cathepsin B; 0.93, 95% CI; 0.37-2.30, p= 0.87. Plasma cathepsin B levels were higher in persons with AD compared to healthy controls whereas there was no difference between diagnostic groups in cathepsin B levels in CSF. Further investigation of cathepsin B as a predictor of AD is warranted.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Multiple lines of research suggest that increased cystatin C activity in the brain protects against the development of Alzheimer disease (AD). METHODS: Serum cystatin C levels were analyzed at two examinations of the Uppsala Longitudinal Study of Adult Men, a longitudinal, community-based study of elderly men (age 70 years, n = 1,153 and age 77 years, n = 761, a subset of the age 70 examination). Cox regressions were used to examine associations between serum cystatin C and incident AD. AD cases were identified by cognitive screening and comprehensive medical chart review in all subjects. RESULTS: On follow-up (median 11.3 years), 82 subjects developed AD. At age 70 years, lower cystatin C was associated with higher risk of AD independently of age, APOE4 genotype, glomerular filtration rate, diabetes, hypertension, stroke, cholesterol, body mass index, smoking, education level, and plasma amyloid-beta protein 40 and 42 levels (hazard ratio [HR] for lowest [<1.12 micromol/L] vs highest [>1.30 micromol/L] tertile = 2.67, 95% CI 1.22-5.83, p < 0.02). The results were similar at age 77 years (43 participants developed AD during follow-up). Furthermore, a 0.1-mumol/L decrease of cystatin C between ages 70 and 77 years was associated with a 29% higher risk of incident AD (HR 1.29, 95% CI 1.03-1.63, p < 0.03). CONCLUSIONS: Low levels of serum cystatin C precede clinically manifest Alzheimer disease (AD) in elderly men free of dementia at baseline and may be a marker of future risk of AD. These findings strengthen the evidence for a role for cystatin C in the development of clinical AD.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: Vascular risk factors are associated with ischemic changes in the cerebral white matter. We studied the predictive value of cognitive test performance especially related to subcortico-frontal pathways, together with a cognitive screening test, for later incidence of fatal or nonfatal stroke or TIAs and stroke subtypes. METHODS: A sample of 930 70-year-old men without previous stroke/TIA from the community-based Uppsala Longitudinal Study of Adult Men was investigated at baseline using Trail Making Tests (TMT) A and B and the Mini-Mental State Examination (MMSE). RESULTS: During up to 13 years of follow-up, 166 men developed a stroke or TIA; 105 participants had a brain infarction. In Cox proportional hazards analyses adjusting for education, social group, and traditional cardiovascular risk factors, a 1-SD increase in TMT-B time was associated with a higher risk for brain infarction (hazard ratio 1.48, 95% confidence interval 1.11-1.97). The risk of brain infarction was more than threefold higher in the highest (TMT-B = 146-240 s) compared to the lowest (TMT-B = 43-84 s) TMT-B quartile. TMT-A and MMSE results were not consistently related to stroke outcomes. CONCLUSION: Impaired performance in elderly men measured by Trail Making Test B, a cognitive test especially reflecting subcortico-frontal activities, was an independent predictor of subsequent brain infarction in this community-based sample of elderly men. Our results extend previous findings of cognitive decline as an independent predictor of stroke and indicate that the risk of brain infarction is increased already in the subclinical phase of cognitive deficit.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND/AIMS: Genetic factors influencing common complex conditions have proven difficult to identify, and data from numerous investigations have provided incomplete conclusions as to the identity of these genes. Here we aimed to identify susceptibility genes for late-onset Alzheimer's disease (AD). METHODS: The case-control analysis included samples from 86 AD patients and 404 cognitively healthy controls selected from the Uppsala Longitudinal Study of Adult Men (ULSAM). In the incidence analysis, all 1,088 genotyped ULSAM participants were included. DNA samples from ULSAM participants were analyzed for 2,578 single nucleotide polymorphisms (SNP) within 368 genes. The selection of genes tested for association to AD within this cohort was based on genes previously implicated in conditions with relevance to ULSAM, such as dementia, cardiovascular disease, diabetes and metabolic syndrome, osteoporosis, and cancer. RESULTS/CONCLUSION: Association analysis revealed 82 genes containing at least 1 significant SNP at p < 0.05 with association to AD. Only 20 genes remained significant after a permutation test to correct for multiple comparisons within individual genes. Using publicly available data from 2 genome-wide association (GWA) studies and linkage disequilibrium data from HapMap, we attempted to replicate the AD association identified in ULSAM. In addition to apolipoprotein E, we were able to replicate 5 other genes in both GWA studies at p < 0.05.

The normal equilibrium between CSF and plasma amyloid beta levels is disrupted in Alzheimer's disease
- 2007

Tidskriftsartikel (refereegranskat)abstract
- Amyloid-beta (A beta) with 40 (A beta 40) and 42 (A beta 42) amino acids, the main components of amyloid plaques in the Alzheimer's disease (AD) brain, can be measured in human cerebrospinal fluid (CSF) and plasma. Whereas CSF A beta 42 is decreased in AD, some studies have reported changed plasma A beta levels in AD and in subjects with mild cognitive impairment (MCI). To this date it is unclear if and how CSF and plasma levels of A beta correlate with each other in healthy individuals, albeit earlier studies on AD patients found no correlation between CSF and plasma A beta. We have measured A beta 40 and A beta 42 in paired CSF and plasma samples from patients with AD (n=39), MCI (n=29) and healthy control subjects (n= 18). We observed a clear correlation between CSF and plasma levels for both A beta 40 and A beta 42 in healthy individuals, whereas no such correlation could be seen for AD or MCI cases. Similarly to other studies we also found low levels of A beta 42 in AD CSF, whereas there were no significant differences in plasma A beta levels between the diagnostic groups. Our findings suggest that the normal equilibrium between CSF and plasma A beta may be disrupted with the initiation of amyloid deposition in the brain.

Better quality of end-of-life care for persons with advanced dementia in nursing homes compared to hospitals : a Swedish national register study
- 2020
-
Ingår i: BMC Palliative Care. - : BioMed Central. - 1472-684X. ; 19:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Hospitalisation of patients with advanced dementia is generally regarded as less preferable compared to care at home or in a nursing home. For patients with other diagnoses, young age has been associated with better end-of-life care. However, studies comparing the quality of palliative care for persons with advanced dementia in hospitals and nursing homes are scarce. The aim of this study was to investigate whether quality of end-of-life care for patients with dementia depends on age, gender and place of death.Methods: The Swedish Register of Palliative Care (SRPC) was used to identify patients who died from dementia in hospitals or nursing homes during a three-year period. The likelihood of death occurring at a hospital, based on age and gender differences, was calculated. Associations between 13 end-of-life care quality indicators collected from the SRPC and age, gender and place of care were examined in a logistic regression model.Results: Death at a hospital was associated with poorer quality of end-of-life care for 10 of the 13 measured outcomes when compared to death at a nursing home, and with better quality according to two of the outcomes. Death at a hospital was more common for men compared to women and for younger patients compared to older. Receiving fluids intravenously or via enteral tube in the last 24 h of life was strongly associated with death at a hospital. Women were more likely to have their oral health assessed and less likely to have pressure ulcers at death. Eight of 12 end-of-life care outcomes showed better results for the age group 65 to 84 years compared to those 85 years or older.Conclusions: Death in hospitals was associated with poorer quality of end-of-life care compared to death in nursing homes. Our data support the importance of advance care planning and individual assessments in nursing homes to avoid referral to hospitals during end of life. Despite established recommendations to avoid hospitalisation if possible, there were strong associations between younger age, male gender and hospitalisation in the end of life. Further studies are needed to investigate the role of socioeconomic factors in end-of-life care for this patient group.

Tidskriftsartikel (refereegranskat)abstract
- Introduction Globally, dementia is one of the leading causes of death. Given the growing elderly population in the world, the yearly number of deaths by dementia is expected to increase. Patients dying from dementia are reported to suffer from a burden of symptoms similar to that of patients with cancer, but receive less medication against symptoms, have a lower probability of palliative care planning and seldom have access to specialised palliative care. Studies investigating the quality of palliative care in dementia are scarce. The aim of this Swedish national study was to compare the quality of end-of-life care between patients with dementia and patients with cancer regardless of place of care. Methods Thirteen end-of-life care quality indicators collected by the Swedish Register of Palliative Care (SRPC) were compared between patients dying from dementia and patients dying from cancer. Data were collected from deaths occurring in nursing homes, hospitals, specialised and general palliative home care, and palliative in-patient units during a three-year period (during March 2012 to February 2015). Analyses were performed using a multivariable logistic regression model, adjusted for age and gender. A subgroup of patients with Alzheimer's disease was identified and compared to patients with other and unspecified types of dementia. Results A total of 4624 deaths from Alzheimer's disease, 11 804deaths from other dementia diagnoses and 51 609 deaths from cancer were included. For six of the 13 quality indicators examined (prescription of PRN drugs against nausea and anxiety, information and bereavement support offered to next of kin, pain assessment and specialised palliative care consultations), poorer outcomes were shown for the dementia group in comparison to the cancer group. Two outcomes (prevalence of pressure ulcers and fluid therapy during the last 24 hours in life) showed better outcomes for the dementia group. The outcomes for the 13 quality indicators were similar for patients with Alzheimer's disease compared to patients with other and unspecified types of dementia. Conclusions The findings in this study indicates that patients dying from Alzheimer's disease and other types of dementia receive a poorer quality of end-of-life care concerning several important end-of-life care areas when compared to patients dying from cancer. Guidelines for end-of-life care in Sweden cannot explain or justify these differences. Further studies are needed to find possible ways to improve end-of-life care in the large and growing group of patients dying from dementia.

Projects accomplished by the Selective Fisheries Secretariat 2014-2017 : a synthesis report
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Commissioned by the Swedish Agency for Marine and Water management, the Swedish University for Agricultural Sciences, established a Secretariat for selective fishing between 2014 and 2017. The secretariat main task has been to gather and evaluate ideas of new gears from the industry on how to minimize unwanted catches. The industry´s initiative and engagement are essential for the successful development of new ideas. All projects have followed the same work flow; a development of project ideas by science-industry collaboration, an industry lead development phase and finally scientific evaluation and reporting.Thirty-four projects have been completed between 2014 and 2017. The separate projects have been reported yearly123 (in Swedish). As there is also an apparent need to interact with similar initiatives in other countries and to disseminate to an international audience we here summarize all 34 projects according to the results of the scientific evaluations, their applicability given current fisheries regulations and fishing practises and also on the up-take of the new gears. The report is divided between active and passive gears and the different projects are grouped based on fisheries (gear type and target species). In the end of the report, fact sheets is included for the most relevant project.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- På uppdrag av Havs- och vattenmyndigheten (HaV), som har ansvarat för regeringsuppdraget selektivt fiske, upprättade SLU Aqua ett Sekretariat för selektivt fiske mellan 2014 och 2017. Sekretariatets huvuduppgift har varit att samla in idéer tillsammans med näringen, för att stimulera utvecklingen av selektiva fiskemetoder i syfte att minska mängden oönskad fångst. Näringens initiativ och engagemang har varit helt avgörande för en framgångsrik utveckling av nya idéer. Under projektperioden har sekretariatet tillsammans med näringen drivit 34 projekt inom selektivt fiske. Samtliga projekt är vetenskapligt utvärderade och redovisade i årliga verksamhetsrapporter. I denna syntesrapport sammanställs resultaten från projekt med liknande problemställningar, målarter och fiskemetoder, till olika fisken. De olika fiskena är uppdelade mellan aktiva och passiva redskap. I sammanställningen har alla projekten bedömts efter en 5-gradig skala som sammanfattar resultatet av den vetenskapliga utvärderingen, redskapets tillämpbarhet i verkligt fiske samt behov av förvaltningsåtgärder och/eller andra incitament för att redskapen verkligen skall komma till bred användning i fisket.

- Den 14:e utgåvan av den samlade resursöversikten av fisk- och kräftdjursbeståndens status i våra vatten.I rapporten kan du ta del av bedömningen som görs av situationen för bestånd som regleras inom ramen för EU:s gemensamma fiskeripolitik (GFP). Bedömningarna baseras på det forskningssamarbete och den rådgivning som sker inom det Internationella Havsforskningsrådet (ICES).De bestånd som förvaltas nationellt baseras på de biologiska underlagen, och rådgivningen i huvudsak på den forskning och övervakning samt analys som bedrivs av Institutionen för akvatiska resurser vid Sveriges lantbruksuniversitet (SLU Aqua) samt yrkesfiskets rapportering.Rapporten omfattar 41 fiskarter och åtta skaldjursarter.Nytt för i år är att flodkräftan och signalkräftan har fått egna presentationer. Vi har även ett nytt kapitel "Hållbarhetsbedömning av fisk- och skaldjursbestånd i havsområden runt Sverige”. Det består av en sammanfattning av den årliga bedömningen av hållbarheten i nyttjandet av fisk- och skaldjursbestånd i kust och hav runt Sverige. Bedömningenär baserad på de senaste tre åren vilket möjliggör en jämförelse över tid iantalet hållbart nyttjade bestånd. Jämförelsen visar inga tydliga förändringar över de senaste tre åren.Det finns ett nytt avsnitt i kapitlet ”Från biologi till förvaltning” om hur Havs- och vattenmyndighetens tillståndsgivning går till, och hur bedömningen baseras på resursöversikten vid ansökan om fiskelicens eller annan tillståndsgivning. Kapitlet har också utökats med ett avsnitt där SCB:s fritidsfiskeundersökning beskrivs och hur resultatet används i beståndsanalyserna.

Tidskriftsartikel (refereegranskat)abstract
- The importance of external and internal population processes in determining variation in reproductive output and variation in population size were quantified with model simulations for open populations of the sequentially hermaphroditic limpet Patella vulgata using field data from the Isle of Man and South West Ireland. Cross-correlation analyses of model outputs and elasticity analyses show that population dynamics are dominated by the effects of large females, and that recruitment adds little to reproductive output. However, populations experiencing low but highly variable recruitment appear male limited and recruitment pulses carrying young males into the population are correlated to reproductive output with a 2-5-year lag. We conclude that pulses in recruitment can be a major structuring force in these limpet populations, but site-specific post-recruitment processes will determine the relative importance of recruitment to population dynamics and the lag between recruitment and reproductive output.

H.O.P.E : Ett frågeformulär på svenska för att identifiera religiösa, andliga och existentiella behov

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Bakgrund: Enligt WHO kännetecknas palliativ vård av helhetssyn med mål att möta fysiska, psykiska, sociala liksom religiösa, andliga och existentiella behov. Att möta existentiella behov förbättrar livskvaliteten men forskningen visar att många patienter i palliativ vård har otillräckligt mötta existentiella behov. Det saknas frågeformulär på svenska för att identifiera och möta existentiella behov i palliativ vård.Syfte: Att utvärdera patienters och personals erfarenheter av att använda en svensk översättning avfrågeformuläret H.O.P.E (Hope, Organized Religion, Personal practices, Effects on medical care) vid en palliativ slutenvårdsenhet.Metod: H.O.P.E översattes från engelska till svenska genom ”double back translation”. Sex patienter, en sjuksköterska, en läkare och en kurator deltog i djupintervjuer om erfarenheter av att använda H.O.P.E i samtal med patienter. Intervjuerna spelades in digitalt, transkriberades och analyserades med hermeneutisk ansats.Resultat: Patienter och personal upplevde att H.O.P.E var applicerbart, uppskattat och relevant att använda vidsamtal om religiösa, andliga och existentiella behov. H.O.P.E associerades med känslor av att ”känna sig sedd” och bidrog till att identifiera coping strategier hos patienterna. I samtalen identifierades och adresserades existentiella frågor som mening, hopp, skuld och ånger som följdes upp vid behov. Modifieringar föreslogs av språk som ibland kändes akademiska. Separering föreslogs av vissa frågor. Aspekter av existentiella behov som hopp/hopplöshet, mening/meningslöshet, skuld och ansvar skulle kunna adresseras ytterligare för att bättre möta en sekulär kontext.Betydelse: Studiens resultat visade att den svenska versionen av H.O.P.E är användbart, uppskattat och relevant vid samtal med patienter i palliativ vård om religiösa, andliga och existentiella behov. Modifiering avspråk, uppdelning i flera frågor och tillägg av fler frågor utifrån en sekulär kontext skulle ytterligare förbättra formuläret. Framtida studier behövs för utveckling och validering av formuläret.

Tidskriftsartikel (refereegranskat)abstract
- Inflammation is suggested to be involved in the pathogenesis of Alzheimer's disease (AD). Serum interleukin-6 (IL-6) and high sensitivity serum reactive protein C (hsCRP) as markers of systemic inflammation were analyzed at two examinations of the ULSAM-study, a longitudinal, community-based study of elderly men (age 70, n = 1062 and age 77, n = 749). In addition, serum amyloid protein A (SAA) and urinary prostaglandin F2alpha (PGF2alpha) metabolite levels were analyzed at age 77 in this cohort. Two serial samples (at ages 70 and 77) were available from 704 individuals. Using Cox regression analyses, associations between serum IL-6, hsCRP, SAA and PGF2alpha metabolite levels and risk of AD, any type of dementia (all-cause dementia) and non-AD dementia were analyzed. On follow-up (median, 11.3 years) in the age 70 cohort, 81 subjects developed AD and 165 subjects developed all-cause dementia. Serum IL-6, hsCRP, SAA, or PGF2alpha levels were not associated with risk of AD. At age 70, high IL-6 levels were associated with an increased risk of non-AD dementia (Hazard ratio 2.21 for above vs. below/at median, 95%confidence interval 1.23-3.95, p-value = 0.008). A longitudinal change in CRP or IL-6 levels was not associated with AD ordementia. In conclusion, Serum IL-6, hsCRP, SAA, and PGF2alpha levels are not associated with the risk of AD. High serum IL-6 levels may be associated with increased risk of non-AD dementia.

Tidskriftsartikel (refereegranskat)abstract
- Oxidative stress in the brain is suggested to be involved in the pathophysiology of Alzheimer's disease (AD). In this study, serum alpha- and gamma-tocopherol, the two major systemic antioxidants, were analyzed at two examinations of the ULSAM-study, a longitudinal, community-based study of elderly men (age 70, n = 616 and age 77, n = 761). In addition, urinary F2-isoprostane levels, as markers of systemic oxidative stress, were analyzed at the age of 77 in this cohort (n = 679). Cox regression analyses were used to examine associations between serum alpha-, gamma-tocopherol and urinary F2-isoprostane levels and AD, any type of dementia (all-cause dementia) and non-AD dementia. On follow-up (median, 12.3 years), 40 subjects developed AD and 86 subjects developed all-cause dementia. Serum alpha- and gamma-tocopherol or urinary F2-isoprostane levels were not associated with the future risk of AD or dementia. In conclusion, systemic serum alpha- and gamma-tocopherol and urinary F2-isoprostane levels are not associated with the future risk of AD or dementia and do not seem to be useful predictors of clinical AD or dementia.
