Om mig

  • Jag är docent och lektor i klinisk epidemiologi, fokuserad på hur vi kan använda epidemiologiska studier för att bidra med information av nytta för patienter och vårdgivare, för att bättre förstå en viss sjukdom, och fatta mer välinformerade beslut om dess behandlingar.

    Som metodorienterad epidemiolog är jag särskilt inriktad på studiedesign, biostatistik och hur vi bäst kan använda register och andra hälsodatakällor för att komplettera information från randomiserade prövningar. Som en del av detta ger jag kurser i SAS-programmering, och under 2020 till 2022 jobbade jag vid Socialstyrelsen med datakvalitetsfrågor runt nationella sjukvårds- och socialtjänstregister. Sedan mars 2023 driver jag frågor som rör tillgång till hälsodata för forskning inom Clinicum -initativet, organiserat metodstöd för klinisk och translationell forskning, med finansiering av KI och Region Stockholm.

Forskningsbeskrivning

  • I mitt team, och genom samarbeten med andra forskargrupper, driver jag en rad olika forskningsprojekt inom kroniska inflammatoriska sjukdomars epidemiologi. Projekten kan grovt delas in i farmakoepidemiologiska projekt som rör långstidsuppföljning och läkemedelssäkerhet för patienter inom reumatiska sjukdomar eller multipel skleros, och mer etiologiska studier med ett fokus på familjehistoria som prediktor och prognostisk markör för reumatoid artrit och komorbida tillstånd. Min forskning finansieras av anslag från bland andra amerikanska Patient Centered Outcomes Institute (PCORI), Vetenskapsrådet, Reumatikerförbundet, NEURO och MS-forskningsfonden. Mitt arbete inom Anti-Rheumatisk Terapi I Sverige (ARTIS)-projektet har finansierats genom avtal mellan Karolinska Institutet och flera läkemedelsföretag

    Multiple sclerosis (MS), a chronic inflammatory and neurodegenerative condition, is a major driver of disability and healthcare costs among young to middle-aged adults. Access to disease-modifying treatments (DMTs) early in the disease course is thought to have improved prognosis, but outcomes vary greatly between patients. Major knowledge gaps remain on prognostic markers and on the benefit-risk balance of specific DMTs strategies in real world populations, with little evidence to guide the choice of DMT for individual patients. This prompted us to establish Combat-MS: a nationwide study following 3500 participants to answer which initial or secondary DMT strategy that, at the group level, best preserves quality of life and neurological functions. This unique cohort combined prospective serum samples and clinical evaluations with rich data from national registers, resulting in a series of influential publications. With this proposal, the cohort will be expanded further with promising biomarkers, imaging and electronic medical record data, covering patients’ trajectories from first healthcare contacts to long-term treatment outcomes. Analyzing this rich data with state-of-the art biostatistics and machine learning, my team will build a framework for a precision medicine approach to MS, providing individualized risk predictions at different clinical stages and evaluating the benefit-risk of distinct DMT strategies across diverse MS populations.

    Multiple sclerosis (MS) features aberrant adaptive immune reaction towards central nervous system antigens leading to myelin and neuron/axon damage. Disease modulatory therapies (DMTs) are highly effective in the initial inflammatory phase, but much less so in later progressive disease phases. We have recently invested 8.6 MUSD in the largest real-world study of MS in a nationwide population-based material, providing a unique basis for advancing our knowledge how MS evolves from a first triggering event to late progressive stages. We hypothesize that chronic infection of memory B cell clones with Epstein-Barr virus (EBV) drives the early inflammatory component of MS, and that innate immune mechanisms and accelerated aging explain progressive MS. The first aim will be addressed using advanced immunophenotyping of our unique MS cohort with full B cell repletion following antiCD20 therapy and a treatment trial with antivirals (collaboration Bergen). We will address the second aim with epidemiological techniques and large-scale soluble biomarker and brain imaging profiling (collaboration Oslo, Basel), supplemented with deep brain imaging and molecular cerebrospinal fluid characterization in smaller clinical materials. Our previous research has transformed treatment of MS in Sweden in a unique way. With this 5-year program we will make considerable progress towards implementation of precision medicine and further improve long-term outcomes for those affected by MS.

    Multiple sclerosis (MS), a chronic inflammatory and neurodegenerative condition, is a major cause of disability and driver of healthcare costs among young and middle aged adults. Access to a range of disease-modifying treatments (DMTs) have improved outlooks for most patients. Major knowledge gaps remain on the benefit-risk balance of specific DMTs strategies in real world populations, however, with little evidence to guide the choice of DMT for individual patients. This prompted us to launch Combat-MS, a nationwide observational drug trial following 3500 participants from 2017 to 2022 to answer which initial or secondary DMT strategy that, at the group level, best preserves quality of life and neurological functions. Nearing its end, the study has generated important insights on safety/effectiveness of major DMTs, also gaining major international interest. With this proposal, we wish to expand the cohort with further national registry and biomarker data and implement new prediction techniques to move from the group level to more individualized prognostication, including how DMT switches or extended dosing intervals interact with patient characteristics to predict treatment outcomes, and with a special focus on off-label use of rituximab. Analyzing this rich data with state-of-the art biostatistics and machine learning, we will build a framework for a precision medicine approach to MS, evaluating the benefit-risk of distinct DMT strategies across diverse MS populations.
