- Objective: To describe the effects of switching treatment from ongoing first-line injectable therapies to rituximab on inflammatory activity measured by MRI and levels of CSF neurofilament light chain (CSF-NFL) in a cohort of patients with clinically stable relapsing-remitting multiple sclerosis (RRMS).Method: Seventy-five patients with clinically stable RRMS treated with the first-line injectables interferon-β (IFN-β) and glatiramer acetate (GA) at 3 Swedish centers were switched to rituximab in this open-label phase II multicenter study. After a run-in period of 3 months, 2 IV doses of 1,000 mg rituximab were given 2 weeks apart followed by repeated clinical assessment, MRI, and CSF-NFL for 24 months.Results: The mean cumulated number of gadolinium-enhancing lesions per patient at months 3 and 6 after treatment shift to rituximab was reduced compared to the run-in period (0.028 vs 0.36, p = 0.029). During the first year after treatment shift, the mean number of new or enlarged T2 lesions per patient was reduced (0.01 vs 0.28, p = 0.004) and mean CSF-NFL levels were reduced by 21% (p = 0.01).Conclusions: For patients with RRMS, a treatment switch from IFN or GA to rituximab is associated with reduced inflammatory activity measured by MRI and CSF-NFL.Classification of evidence: This study provides Class IV evidence that rituximab has an equal or superior effect in reducing inflammatory activity in RRMS measured by MRI and CSF-NFL compared to first-line injectables during the first year after treatment shift.

- Rapidly expanding knowledge of the molecular landscape of cancers has resulted in the implementation of an increasing number of specific therapies targeted at tumors with specific molecular aberrations. In response to this development, new tools for predictive testing for molecular targets need to be implemented in routine health care. To achieve robust future molecular diagnostic pathology, and equal opportunity for patients to qualify for targeted therapy, the national working group for Solid Tumors in the initiative Genomic Medicine Sweden (GMS) aims to implement regional and national platforms for comprehensive genomic tumor profiling and linked analysis pipelines. Novel IT-infrastrucutures and recruitment of bioinformaticians and molecular biologists to hospital labotatories are paramount. The infrastructure will allow wider inclusion into clinical trials and supplement the national cancer registries with molecular »real world data« for research and evaluation of implemented cancer therapies and diagnostic procedures.

- Introduction: Fecal calprotectin (FC) is anoninvasive tool for examining response to biologics in inflammatory boweldisease (IBD), but its performance in relation to other novel fecal markers of various cellular origins is unknown.Methods: We performed a prospective multicenter cohort study and included patients with active IBD who provided a fecal sample at initiation of biological therapy. Levels of FC, myeloperoxidase (MPO), human neutrophil lipocalin (HNL), and eosinophil-derived neurotoxin (EDN) were analyzed and related to clinical remission status at 3 months. Changes in levels of markers at 3 months were calculated, and the impact of concomitant use of corticosteroids at baseline was estimated.Results: In patients achieving clinical remission (n = 27), a decrease in levels of FC (P = 0.005), MPO (P < 0.001), HNL (P < 0.001), and EDN (P < 0.001) was observed, whereas no significant decrease was seen in patients not achieving remission (n = 39). There was a significant difference in the change in the level of MPO (P = 0.01) and HNL (P = 0.02) between patients achieving clinical remission and those who did not, but changes in FC and EDN could not differentiate between these groups. Patients with concomitant systemic corticosteroids at inclusion had lower levels of HNL (P = 0.01) and EDN (P < 0.001) at baseline, compared with patients without corticosteroids.Discussion: Fecal MPO, HNL, and EDN are all promising biomarkers for assessing the treatment outcome of biologics in patients with IBD. Fecal levels of EDN and HNL are significantly affected by corticosteroids indicating a greater sensitivity to the effects of corticosteroids compared with levels of FC and MPO.
