Assessment of Erythrocytes Methotrexate Polyglutamate Three Levels in Psoriatic Patients Treated with Methotrexate Monotherapy and Their Association with Disease Response.
Article in Indian journal of clinical biochemistry : IJCB, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Methotrexate is used to manage moderate to severe psoriasis and psoriatic arthritis. Methotrexate acts by inhibiting the enzymes involved in nucleotide synthesis. Methotrexate polyglutamates (MTXPGs) have a higher potency to inhibit Dihydrofolate reductase (DHFR), 5-aminoimidazole-4-carboxamide ribonucleotide transformylase (ATIC), and thymidylate synthase (TS), compared to naïve methotrexate. Among all the MTXPGs, methotrexate polyglutamate three (MTXPG-3) is a more potent inhibitor of DHFR, ATIC, and TS enzymes. MTXPG-3 is anticipated to allow therapeutic drug monitoring in immune-mediated inflammatory diseases. We aim to study MTXPG-3 levels as a biomarker for both efficacy and adverse events among psoriatic patients treated with methotrexate monotherapy. We used the LC-MS/MS (Liquid Chromatography Mass Spectrophotometry) system for measuring erythrocyte MTXPG-3. We recruited 106 patients with psoriasis who were treated with methotrexate. Sixty-one of them had psoriatic arthritis (concomitant or in the past). The mean age was 45.08 ± 13.04 years. After twenty-four weeks of methotrexate treatment, 73(69%) were responders, and 33(31%) were non-responders. Thirty-nine (36%) experienced adverse effects, and 67(64%) did not experience any adverse effects. We observed a significant positive correlation between erythrocyte MTXPG-3 and methotrexate dose per week at weeks 12 and 16 but not at week 24. Erythrocyte MTXPG-3 did not correlate with response or adverse effects. It can be used as a marker of compliance.
