Evaluation of relationship between inflammatory markers and hyperemesis gravidarum in patients admitted to emergency department.

BACKGROUND: Hyperemesis gravidarum (HG) is defined as severe nausea and vomiting in pregnancy and considered as one of the most frequent causes to emergency department (ED) admissions. Previous research has shown that HG is associated with systemic inflammation, but there have been no prospective studies to explore this link. The objective of this study was to assess the impact of inflammation in HG pathophysiology and to investigate the association between severity of HG and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and CRP in patients who were admitted to ED with nausea and vomiting. METHODS: This prospective study has been conducted in a tertiary clinic between 2015 and 2016. A total of 162 patients with <16 weeks gestation with singleton pregnancies and without any chronic diseases enrolled in the study. The study group consisted of 113 patients with HG and the control group included 49 healthy subjects. PUQE Index and VAS were used to evaluate the severity of symptoms. RESULTS: Demographical data were similar between both groups. The study group demonstrated significantly higher NLR, PLR and CRP levels (NLR 3.39 vs 2.5, p = 0.001; PLR 134.3 vs 111.2, p = 0.005; CRP 0.85 mg/dL vs 0.19 mg/dL, p = 0.001). While NLR and PLR levels were not correlated with severity of HG, CRP levels were associated with severity of disease (p = 0.001) regarding to PUQE index. CONCLUSION: NLR and PLR are easily obtained and routinely used diagnostic tools for various inflammatory diseases. Measurement of this markers might provide useful information in HG pathogenesis and diagnosis.

Effect of initial lactate level on short-term survival in patients with out-of-hospital cardiac arrest.

PURPOSE: This study evaluated whether serum lactate levels (SLL) at admission in patients with cardiac arrest (CA) can predict successful return of spontaneous circulation (ROSC) or short-term survival, especially within the first 24 h. MATERIALS AND METHODS: This prospective, observational study was conducted in the emergency department (ED) of a training and research hospital from April 2015 through February 2016. It included all patients older than 18 years who presented to the ED during the study period with non-traumatic out-of-hospital cardiac arrest (OHCA). The study measured two outcomes: whether ROSC was achieved and whether short-term survival was achieved. ROSC was defined as the presence of spontaneous circulation for the first hour after cardiopulmonary resuscitation (CPR). Survival was defined as having survived for a minimum of 24 h after ROSC. RESULTS: The study included 140 patients who were admitted to the ED with OHCA. ROSC was achieved in 55 patients (39.3%), and survival for 24 h following CA was achieved in 42 patients (30%). The mean SLL in the ROSC (+) and ROSC (-) groups were 9.1 ± 3.2 mmol/L and 9.8 ± 2.9 mmol/L, respectively. The mean SLL in the survivor and non-survivor groups were 8.6 ± 2.9 mmol/L and 10 ± 3.1 mmol/L, respectively. These differences were not statistically significant (p = 0.1). A multivariate regression model assessing the factors that predicted both ROSC and 24-h survival showed the odds ratio (OR) of initial SLL was 1.3 (95% CI: 1.05-1.6) and 1.1 (95% CI: 0.9-1.3), respectively. CONCLUSIONS: This study showed that in OHCA patients, SLL on admission was not associated with increased ROSC achievement or 24-h survival.
