Influence of post-transplant immunosuppressive therapy on gastrointestinal transit using biomagnetic method: a pilot study.

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
backgroundImmunosuppressive therapy after kidney transplant is necessary to prevent allograft rejection and it is the cause of several gastrointestinal (GI) disorders that have been scantily studied.
objectivesThis study was aimed at investigating the influence of triple immunosuppressive therapy on GI transit in renal transplant patients by employing a biomagnetic technique.
methodsTwenty-one renal transplant patients underwent triple therapy, which included either tacrolimus (TAC) or cyclosporin A (CsA) associated with prednisone and azathioprine. They were all evaluated, and fifteen other healthy individuals formed the control group. After a standardized meal, GI transit of magnetic markers was assessed using Alternating Current Biosusceptometry (ACB).
resultsPatients taking TAC had significantly accelerated gastric emptying and colonic arrival (p ≤ 0.001) when compared with those taking CsA and those in the control group. However, no differences were observed in small bowel transit among the groups studied. Overall, the inter-subject coefficients of variation for gastrointestinal transit parameters were higher for the TAC group and similar for the CsA and control groups.
conclusionThis study demonstrated that ACB is a suitable methodology when evaluating the influence of different immunosuppressive therapies on gastrointestinal transit after renal transplantation. Pronounced inter-individual variation was found in patients treated with tacrolimus, thus showing the prokinetic effect of this drug on GI motility. Studies of motility patterns in this population could be useful as complementary information toward determining the mechanisms and the relationship between motility and therapeutic doses.
