Clinical significance of pyuria in pediatric diabetic ketoacidosis: evidence against empirical antibiotic use.
Observational study in Pediatric endocrinology, diabetes, and metabolism, 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
introductionDiabetic ketoacidosis (DKA) can be associated with severe morbidity and mortality in pediatric patients with type 1 diabetes mellitus, such as pyuria. Clinical association of pyuria with urinary tract infections (UTIs) remains unclear. Misinterpretation of sterile pyuria may lead to unnecessary antimicrobial treatment and hospitalization. The aim of the study was to assess pyuria frequency and its clinical relevance by examining clinical, laboratory, and biochemical parameters in pediatric cases with DKA. MATERIAL AND
methodsThe prospective observational study enrolled 150 children with DKA (1-14 years) who were diagnosed based on the International Society for Pediatric and Adolescent Diabetes criteria and admitted to the Children Welfare Teaching Hospital emergency department. Cases were evaluated by clinical history, physical examination, and laboratory parameters (urinalysis, urine culture, random blood sugar, white blood cell count, platelet count, arterial blood gas analysis, bicarbonate level, blood urea, and serum creatinine). Clinical and laboratory parameters were compared between pyuric (63/150) and non-pyuric groups (87/150).
resultsPyuria was observed in 42% of DKA cases; only 4.7% had culture-confirmed UTIs. Pyuria was significantly associated with older age (p = 0.02), female sex (p < 0.001), lower random blood glucose (p = 0.03), and lower PaO2 (p = 0.009). Degree of dehydration, level of consciousness, serum ketones, and total leukocyte count were insignificant.
conclusionsPyuria is common among pediatric patients with DKA but rarely indicates UTIs. Its presence in DKA patients and correlation with various clinical and biochemical parameters may reflect kidney inflammation, urging more clarification. Routine antibiotic therapy based solely on pyuria is not recommended without clinical or microbiological evidence.
