The natural immune molecules urinary Tamm-Horsfall protein and pentraxin 3 as predictors for recurrent urinary tract infection severity: a single-center self-control 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
objectiveThe innate immune defense plays a pivotal role in protecting the urinary tract from uropathogenic invasion and maintaining immune homeostasis. Dysregulation of the innate immune system can result in recurrent urinary tract infections (RUTI) due to heightened susceptibility to uropathogens. Despite this, predicting the risk of recurrence and the degree of immune compromise in patients who have had one urinary tract infection remains challenging. Also identifying which patients are more susceptible to developing pyelonephritis rather than the more local disease of cystitis is imperfect, although delayed diagnosis of a UTI is a good indicator for developing pyelonephritis. This study aims to assess the potential of urinary Tamm-Horsfall protein (THP) and Pentraxin 3 (PTX3) as predictors of RUTI symptom severity and recurrence, while also evaluating the efficacy of the Chinese herbal formulation Tailin Formula (TLF) as a clinical therapeutic intervention for RUTI.
methodsA single-center cohort study was conducted involving 142 participants, consisting of 31 healthy individuals (non-RUTI group,
resultsUrinary THP levels were significantly lower in RUTI patients (TLF and CLAT groups) compared to the non-RUTI, whereas PTX3 levels showed a tendency toward elevation. After treatment, urinary THP levels were markedly higher in the TLF group (27.43 ± 7.07) compared to pretreatment levels (10.00 ± 2.79), while levels remained lower in the CLAT group (8.91 ± 2.23) than in the TLF group. Urinary PTX3 levels decreased post-treatment in both groups after treatment than before (CLAT: 0.30 ± 0.13 vs. 1.04 ± 0.38; TLF: 0.29 ± 0.12 vs. 1.15 ± 0.36). Additionally, THP was negatively correlated with renal tubular injury markers NAG/Cr and β2-MG in RUTI patients (
conclusionThis study suggests that urinary THP and PTX3 are likely involved in the pathogenesis of RUTI. These biomarkers may serve as valuable predictors for assessing symptom severity, recurrence risk, and therapeutic efficacy in patients with RUTI at risk of disease progression.
