Effects of atorvastatin doses on serum level of procalcitonin and predictors for major adverse cardiovascular events in patients with acute myocardial infarction: a pilot study and post hoc analysis.

BACKGROUND: Inflammation plays an important role in acute myocardial infarction (AMI). Procalcitonin levels rise in response to proinflammatory stimuli. This study aimed to investigate the effects of different doses of atorvastatin on the serum inflammatory profiles, especially procalcitonin and major adverse cardiovascular events (MACEs) in patients with AMI during hospitalization. METHODS: The patients who were admitted to the Coronary Care Unit of The Third Medical Center of PLA General Hospital (Beijing, China) between January 2015 and December 2015 with a diagnosis of AMI were enrolled, and randomized to atorvastatin 20 mg/day postoperatively (20-mg group), 40 mg/day postoperatively (40-mg group) and 80 mg preoperatively+40 mg/day postoperatively (80/40-mg group). Serum procalcitonin and high-sensitivity C-reactive protein (hs-CRP) were evaluated before and at 1 and 3 days after percutaneous coronary intervention (PCI). RESULTS: A total of 112 patients with AMI (23 women and 89 men) were prospectively eligible for the study. There were no significant differences in most clinical data among the three groups. The 80/40-mg group showed significantly reduced serum procalcitonin levels at 1 and 3 days after PCI (P < 0.001) and reduced hs-CRP levels at 3 days P = 0.001) compared with 20-mg and 40-mg groups. Serum procalcitonin (OR, 4.593; 95% CI, 1.476-8.387; P = 0.005), hs-CRP (OR, 1.149; 95% CI, 1.012-1.338; P = 0.018), highly sensitive cardiac troponin T (OR, 1.255; 95% CI, 1.004-1.569, P = 0.009) and Gensini score (OR, 1.022; 95% CI, 1.045-1.062; P = 0.013) were independently associated with MACEs during hospitalization. CONCLUSION: The use of atorvastatin 80 mg before and 40 mg/day after PCI in patients with AMI can effectively reduce serum inflammatory factors. procalcitonin and hs-CRP were independently associated with in-hospital MACEs.

Effects of nutritional support combined with insulin therapy on serum proteins, inflammatory factors, pentraxin-3, and serum amylase levels in patients with diabetic ketoacidosis complicated with acute pancreatitis.

ABSTRACT: To explore the effects of nutritional support combined with insulin therapy on serum protein, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), pentraxin-3 (PTX-3), and serum amylase (AMS) levels in patients with diabetic ketoacidosis complicated with acute pancreatitis.A total of 64 patients with diabetic ketoacidosis complicated with acute pancreatitis admitted to our hospital from January 2018 to February 2019 were enrolled in this prospective study. They were divided into the study group and the control group according to the random number table method, with 32 patients in each group. Patients in the study group were given nutritional support combined with insulin therapy, and patients in the control group were given insulin therapy.There were no significant differences in general data including age, gender, body mass index, course and type of diabetes, acute physiology and chronic health evaluation II, RANSON, CT grades between the 2 groups before treatment (all P > .05). After 7 days of treatment, the clinical efficacy of the study group was significantly higher than that of the control group (study group vs control group, 94.44% vs 75.00%, P < .05). After 7 days of treatment, the levels of prealbumin and albumin in the study group were significantly higher than those in the control group (P < .05). After 7 days of treatment, the levels of PCT, CRP, TNF-α, PTX-3, and AMS in the 2 groups were significantly lower than those before treatment (P < .05), and the levels of PCT, CRP, TNF-α, PTX-3, and AMS in the study group were significantly lower than those in the control group. After 7 days of treatment, the levels of IgG, IgM, and IgA in the 2 groups were significantly higher than those before treatment, and the levels of IgG, IgM, and IgA in the study group were significantly higher than those in the control group (P < .05).Nutritional support combined with insulin is obviously effective in the treatment of diabetic ketoacidosis complicated with acute pancreatitis, which can improve serum protein levels, reduce inflammatory response, improve immune function, and is worthy of clinical application.

The effect of insulin pump combined with ulinastatin on the levels of PCT, TG, PTX-3, and CX3CL1 in patients with diabetic ketoacidosis and pancreatitis.

ABSTRACT: The aim of this research is to observe the effect of insulin pump combined with Ulinastatin on the levels of procalcitonin (PCT), triglycerides (TG), pentraxin-3(PTX-3), and C-X3-C motif chemokine ligand 1 (CX3CL1) in patients with diabetic ketoacidosis and pancreatitis.A total of 72 patients with diabetic ketoacidosis and pancreatitis who were admitted to our hospital from February 2016 to February 2020 were selected as the research subjects. They were divided into study groups (36 cases, given insulin pump combined Ulinastatin treatment) and control group (36 cases, given insulin pump treatment). Statistics of changes in blood amylase (AMS), blood glucose, blood ketones, glycosylated hemoglobin (HbA1c), PCT, TG, PTX-3, and chemokine CX3CL in pancreatic tissue before and after treatment.After treatment, the clinical efficacy of the study group was significantly higher than that of the control group (94.44% vs 75.00%), the difference was significant (P < .05). After treatment, the clinical symptoms (abdominal distension, abdominal pain, body temperature, blood sugar, HbA1c and blood amylase) in the study group were significantly less time-to-normal than in the control group, and the difference was significant (P < .05). After treatment, the AMS, blood sugar, HbA1c, and blood ketones of the 2 groups were all lower than before treatment, and the study group's AMS, blood sugar, HbA1c, and blood ketones were all lower In the control group, the difference was significant (P < .05). After treatment, the 2 groups of PCT, TG, PTX-3, and CX3CL were all lower than before treatment, among which the study group PCT, TG, PTX-3, and CX3CL1 were lower than the control group, the difference was significant (P < .05). After treatment, the total adverse reaction rate of the 2 groups was not significantly different (P > .05), but the total adverse reaction rate of the study group was lower than that of the control group.The combination of insulin pump and ulinastatin in the treatment of patients with diabetic ketoacidosis complicated with acute pancreatitis has a effect, which can shorten the recovery time of clinical symptoms, reduce the levels of PCT, TG, PTX-3, and CX3CL1, and has fewer adverse reactions. It is worthy of clinical application.

Value of serum procalcitonin as an early predictor of antibiotic treatment response in inpatients with pelvic inflammatory disease (VALID).

OBJECTIVE: This study aimed to investigate the value of serum procalcitonin as an early predictor of antibiotic treatment response in the inpatient management of pelvic inflammatory disease (PID). MATERIALS AND METHODS: A prospective observational study was carried out at a university hospital. Patients admitted for pelvic inflammatory disease were classified into 2 groups: responders and non-responders. The primary outcome measure was the serum level of procalcitonin at the time of admission. The secondary outcome measures were other serum inflammatory markers including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and white blood cell (WBC) count. RESULTS: Baseline characteristics were similar between the groups. Serum level of procalcitonin at the time of admission did not differ between the groups (P = 0.564). However, the non-responders had more elevated CRP and ESR compared to the responders (P = 0.045 and P = 0.030, respectively). CRP showed the highest accuracy of 72.1% (95% confidence interval [CI], 59.2 to 82.9) in predicting antibiotics response, while procalcitonin showed the lowest accuracy of 49.1% (95% CI, 35.1 to 63.2). CONCLUSION: Compared with standard inflammatory markers such as CRP or ESR, procalcitonin had limited diagnostic value in predicting antibiotics response in patients admitted for PID. Therefore, procalcitonin measurement cannot be recommended as a laboratory test for patients with PID and the value of its routine use remains inconclusive.

Acute Eosinophilic Pneumonia Presenting with an Elevated Procalcitonin Level: A Rare Laboratory Finding.

BACKGROUND We present the case of a 33-year-old female who was transferred to a tertiary care hospital because of acute respiratory failure. CASE REPORT History, imaging, and laboratory testing (including an elevated procalcitonin level) were consistent with a diagnosis of bacterial pneumonia. However, despite broad spectrum intravenous antibiotics, her condition worsened. Shortly after transfer to our hospital, she required intubation and mechanical ventilation. Bronchoscopy with bronchoalveolar lavage (BAL) was performed and a diagnosis of acute eosinophilic pneumonia was made. After discontinuation of antibiotics and initiation of steroids she improved quickly. CONCLUSIONS Our case highlights the importance of considering alternative diagnoses in patients who appear to have bacterial lower respiratory tract infection, even in those with elevated procalcitonin levels.
