Natalizumab Promotes Activation of Peripheral Monocytes in Patients With Multiple Sclerosis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesNatalizumab (NTZ), a monoclonal antibody against very late antigen-4 (VLA-4), is one of the most efficient therapies to prevent acute relapses in multiple sclerosis (MS). VLA-4 is the key adhesion molecule for peripheral immune cells, especially lymphocytes to enter the CNS. While its blockade thus virtually abrogates CNS infiltration of these cells, long-term exposure to natalizumab may also affect immune cell function.
methodsIn this study, we report that in patients with MS, NTZ treatment is associated with an enhanced activation status of peripheral monocytes.
resultsExpression of 2 independent activation markers, CD69 and CD150, was significantly higher on blood monocytes from NTZ-treated patients when compared with those from matched untreated patients with MS, while other properties such as cytokine production remained unchanged. DISCUSSION: These findings consolidate the concept that peripheral immune cells remain fully competent on NTZ treatment, an excellent asset rare among MS treatments. However, they also suggest that NTZ may exert nondesirable effects on the progressive aspect of MS, where myeloid cells and their chronic activation are attributed a prominent pathophysiologic role.
