A case of kidney disease related to Staphylococcus epidermidis infection soon after insertion of a central venous catheter.

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
Central venous catheter (CVC)-related kidney disease has been well documented in cases of long-term catheter use, typically manifesting as membranoproliferative glomerulonephritis with immunoglobulin (Ig)M and C3 deposits after months to years of catheterization. We report an exceptional case of rapidly progressive kidney disease that developed just 7 days after CVC insertion in a 74-year-old man who underwent laparoscopic rectal cancer surgery. The patient presented with high fever (39 ℃) and acute kidney injury, with serum creatinine rapidly escalating from a baseline of 1.1-2.7 mg/dL. Laboratory evaluation revealed marked hypocomplementemia (C3 35 mg/dL, C4 5 mg/dL), significant proteinuria (1.5 g/day), and hematuria. Catheter tip culture isolated multidrug-resistant Staphylococcus epidermidis. Kidney biopsy demonstrated distinctive pathological findings characterized by endocapillary proliferative glomerulonephritis with massive fibrin deposition, confirmed by phosphotungstic acid-hematoxylin (PTAH) staining. Immunofluorescence revealed granular deposits of IgG and C3 along the capillary wall, notably without IgA or IgM deposits. Electron microscopy identified characteristic fibrin deposits measuring 7-8 nm in thickness, predominantly in the subendothelial region. DnaJ homolog subfamily B member 9 (DNAJB9) staining was negative, definitively excluding fibrillary glomerulonephritis (FGN). Following catheter removal and targeted antibiotic therapy without steroid treatment, the patient's renal function showed remarkable improvement, with creatinine decreasing to 1.8 mg/dL at discharge and further improving to 1.0 mg/dL after 1 year. This case demonstrates that S. epidermidis can induce severe glomerular lesions through fibrin deposition within an extraordinarily short timeframe, contrasting dramatically with the immune complex-mediated injury typically observed in long-term CVC use.
