Immunomodulatory Effects of Nintedanib on Human Blood Monocytes/Macrophages from Patients with Idiopathic Pulmonary Fibrosis.

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
backgroundNintedanib (NTD) is an inhibitor of several tyrosine kinases whose role in the pathogenesis of idiopathic pulmonary fibrosis (IPF) is well recognized. Therefore, NTD was approved for the management of IPF about ten years ago. NTD has been demonstrated to have immunomodulatory effects in vitro. We now evaluated the effects of NTD on monocyte/macrophage phenotype isolated from IPF patients treated with NTD.
methodsMonocytes were isolated from IPF patients naïve for treatments and used as such or differentiated into M1- and M2-like macrophages. The cellular phenotype (characterized by the expression pro- and anti-fibrotic surface markers) and responsiveness (characterized by oxidative stress and cytokine expression/release) were evaluated, at T0 (before treatment starts) and after 6 months of treatment with a 150 mg capsule of NTD twice a day (T1).
resultsFollowing differentiation, both M1 and M2 macrophage populations, derived from monocytes isolated from patients treated with NTD, present a higher percentage of cells positive for anti-fibrotic CD80/CD86 and expressing less profibrotic CD206/CD163. Importantly, gene expression and release of the pro-fibrotic factor TGF-β were significantly decreased at T1.
conclusionsThese results show that although it does not have a direct effect on monocyte phenotype/responsiveness, NTD in vivo appears to prime monocytes to differentiate preferentially towards an anti-fibrotic macrophage phenotype, suggesting that it has an immunomodulatory effect on macrophage polarization. This data leads us to hypothesize that NTD could also induce this change in vivo, thus contributing to the improvement of the patient's fibrotic state.
