Impact of cardiovascular and metabolic comorbidities on severity and outcomes of hospital-acquired sepsis in intensive care patients: a case-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
backgroundSepsis is a life-threatening dysregulated host response to microbial infection often leading to multiorgan failure and cardiovascular complications, which significantly contribute to mortality. This study aimed to identify key risk factors associated with disease severity among sepsis patients with distinct cardiovascular and metabolic comorbidities.
methodsThis hospital-based case-control study included 148 adult patients with sepsis admitted to the intensive care unit (ICU) and 311 non-septic controls with comparable cardiovascular and metabolic comorbidities. Sepsis was diagnosed based on clinical criteria and confirmed by elevated serum procalcitonin levels. Serum procalcitonin, IL-6, IL-10, and TNF-α were measured using chemiluminescent immunoassays. Associations between comorbidities and sepsis severity were evaluated using chi-square tests and logistic regression and survival among sepsis cases was explored using Kaplan-Meier analysis.
resultsMostly infections were caused by Gram-negative bacteria, mainly Klebsiella pneumoniae and Escherichia coli. Elevated serum procalcitonin levels were used to support the diagnosis of sepsis. Compared with controls, sepsis patients showed significant increases in serum levels of IL-6, IL-10 and TNF-α, indicating an enhanced systemic inflammatory response. Statistical analysis showed that cardiovascular diseases, hypertension and type-2 diabetes were significantly associated with increased disease severity. Descriptive survival analyses among sepsis patients suggested lower survival probabilities in those with rheumatic heart disease and peripheral arterial disease.
conclusionsCardiovascular and metabolic comorbidities particularly myocardial infarction and type 2 diabetes mellitus are strongly associated with sepsis requiring intensive care. Elevated inflammatory cytokine levels characterize the systemic immune response in these patients. These findings highlight the importance of early risk stratification in septic patients with underlying cardiometabolic disease.
