Serum chitotriosidase-1 (CHIT1) as candidate biomarker for mitochondriopathies.
Article in Journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundNeuromuscular diseases (NMDs) and mitochondriopathies are rare and heterogeneous disorders. Diagnosis is often difficult and delayed, partly due to the lack of reliable biomarkers. Chitotriosidase (CHIT1) as a candidate marker for lysosomal storage diseases is elevated in Niemann pick disease type C as a prototype of this group of diseases. Most recently, a relevant role of the lysosomal pathway in mitochondriopathies has been discussed, but markers of lysosomal involvement have not been investigated. Therefore, the aim of this study was to evaluate CHIT1 concentrations in a broad spectrum of NMDs and mitochondriopathies.
methodsCHIT1 serum concentration of 151 patients with NMD or primary mitochondriopathy was determined by enzyme-linked immunosorbent assay, and compared to 38 healthy controls and 8 patients with Niemann pick disease type C. Results were controlled for age, sex, CRP and CHIT1 polymorphism, and compared to several established markers (CK, FGF21, GDF15).
resultsCHIT1 levels were not altered in NMDs, but significantly increased in mitochondriopathies, within the range of Niemann-Pick patients. Compared to the established biomarkers, CHIT1 and FGF21 showed a similar diagnostic performance, while better results were found for GDF15. However, there was a tendency for higher CHIT1 concentrations in patients with central nervous system involvement (MELAS syndrome), while FGF21 and GDF15 were not relevantly altered in these patients. Consequently, a combination of biomarkers including CHIT1 provided the best overall diagnostic performance.
conclusionsSerum CHIT1 concentration is significantly elevated in mitochondriopathies compared to healthy controls and other NMD, identifying CHIT1 as potential complementary biomarker in mitochondriopathies.
