“…Numerous studies 28 , 29 , 35 , 39 , 40 have also found that the copeptin levels are significantly elevated during septicemia and increase proportionally with sepsis progression and severity. Likewise, studies have also reported lower admission copeptin levels in sepsis patients who survived 27 , 30 , 35 and these findings are similar to the findings that this meta-analysis produced.…”

Background: Sepsis syndromes are a major burden in the ICU with very high mortality. Vasopressin and copeptin are released in response to hypovolemia and have shown potential significance in diagnosing sepsis. Objective: To investigate the levels of copeptin in patients with sepsis syndromes and evaluate its relation with patient prognosis and mortality. Methods: Four databases were searched for literature published from inception to the 8th of November 2022. Original research articles where copeptin was measured in sepsis patients and compared with controls were included. Data extraction and synthesis: study characteristics, levels of copeptin in the participants, and copeptin assay description were extracted. Levels of copeptin in patients were pooled and compared with controls in terms of the standard mean difference (SMD) generated using a random-effects model. Results: Fifteen studies met the selection criteria. Copeptin levels were significantly higher in patients with sepsis, severe sepsis, and septic shock as compared to controls [(SMD: 1.49, 95% CI: 0.81–2.16, P<0.0001), (SMD: 1.94, 95% CI: 0.34–3.54, P=0.02), and (SMD: 2.17, 95% CI: 0.68–3.66, P=0.004), respectively]. The highest copeptin levels were noted in septic shock patients. The admission copeptin levels were significantly lower in survivors as compared to nonsurvivors (SMD: −1.73; 95% CI: −2.41 to −1.06, P<0.001). Conclusion and Relevance: Copeptin was significantly elevated in sepsis, severe sepsis, and septic shock. Survivors had a significantly lower copeptin during admission. Copeptin offered an excellent predictability to predict 1-month mortality. Measuring the copeptin in sepsis patients can aid treating physicians to foresee patients’ prognosis.
