Assessment of the Relationship between Monocyte to High-Density Lipoprotein Ratio and Myocardial Bridge

Monocyte to high-density lipoprotein ratio is associated with mortality in patients with coronary artery diseases

BACKGROUND

Whether the monocyte to high-density lipoprotein ratio (MHR) is associated with the prognosis of coronary artery disease (CAD) is inconclusive.

METHODS

Patients with CAD were enrolled and their data were collected. Blood was sampled within 24 h after admission. Multivariate Cox regression analysis was performed to determine the relationship between the MHR and all-cause mortality as well as complications during hospitalization.

RESULTS

We included 5371 patients in our cohort study. Among them, 114 (2.12%) patients died in hospital. MHR was independently associated with all-cause mortality (hazard ratio [HR], 1.81; 95% confidence interval [CI] 1.35, 2.42), cardiovascular mortality (1.69; 1.17, 2.45) and non-cardiovascular mortality (2.04; 1.27, 3.28). This association was only observed in patients with hypertension (P for interaction = 0.003). Patients with higher MHR levels also have a higher risk of complications, including infection, pneumonia, electrolyte disturbance, gastrointestinal bleeding, multiple organ dysfunction syndrome, and disturbance of consciousness. The receiver operating characteristic (ROC) analysis showed that the MHR had higher prognostic values than monocytes and high-density lipoprotein.

CONCLUSION

MHR was an independent predictor of all-cause mortality and in-hospital complications in patients with CAD, especially in patients with hypertension.

Predictive Value of High-sensitivity C-reactive Protein to Albumin Ratio and Monocyte to High-density Lipoprotein Ratio in Patients with Brucellosis

Background: Brucellosis is an inflammatory disease that may affect any organ or system. Objectives: The aim of this retrospective cross-sectional study was to investigate the predictive value of novel and traditional inflammatory markers for the diagnosis of brucellosis. Methods: The demographic characteristics and laboratory results of 55 patients with confirmed brucellosis and 60 healthy controls were analyzed and compared. Blood culture was performed using the BacT/ALERT 3D automated system. The presence of Brucella antibodies was detected by both the Brucellacapt test and Brucella Coombs gel test. Complete blood count, erythrocyte sedimentation rate (ESR), and biochemical analyzes were also performed. Results: Compared to healthy controls, the patients with brucellosis had significantly higher high-sensitivity C-reactive protein (hsCRP), hsCRP to albumin ratio (CAR), ESR, monocyte, monocyte to high-density lipoprotein ratio (MHR), aspartate aminotransferase, creatinine levels, while had significantly lower mean platelet volume, lymphocyte to monocyte ratio, albumin, total cholesterol, and high-density lipoprotein levels. There was no significant difference between the two groups in terms of leukocyte count, neutrophil, lymphocyte, hemoglobin, red blood cell distribution width, platelet, neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, glucose, alanine aminotransferase, blood urea nitrogen, triglyceride, low-density lipoprotein levels. Positive correlations were observed between CAR, hsCRP, ESR, and MHR levels. Conclusions: This is the first study evaluating the predictive value of CAR and MHR in the diagnosis of brucellosis. The data revealed that CAR and MHR could be used as the markers of systemic inflammation in patients with brucellosis.

Relationships between monocyte count to high-density lipoprotein cholesterol ratio and cardiovascular outcomes in patients commencing dialysis

Objective

High monocyte to high-density lipoprotein cholesterol ratio (MHR) is known to be a risk factor for cardiovascular (CV) complications. We aimed to evaluate the relationship between MHR and CV outcomes in patients commencing dialysis.

Methods

The medical records of patients who started maintenance dialysis between January 2006 and July 2017 were reviewed. The primary outcomes were all-cause mortality and overall CV mortality and the secondary outcomes were CV event-free survival and the incidence of CV complications.

Results

Five hundred ninety-seven patients were enrolled and allocated to low- or high-MHR groups. All-cause mortality did not differ between the groups during a mean follow-up period of 3.9 years. In addition, overall CV mortality did not differ between the groups. However, CV event-free survival was significantly lower in the high-MHR group than in the low-MHR group (47.5% vs. 59.0%). Multivariate Cox regression analysis showed that high MHR was an independent predictor of CV events (HR 1.886, 95% CI 1.015–3.505).

Conclusion

High MHR at the time of initiation of dialysis may represent a useful predictor of CV complications.

Elevated Monocyte to High-density Lipoprotein Ratios as an Inflammation Markers for Schizophrenia Patients

Objective

Monocyte to high density lipoprotein ratio (MHR) is a new instrument for giving notice inflammation, which plays a main role in schizophrenia. Thus, in this study, our goal was to investigate the possible association between MHR and schizophrenia.

Methods

The participants of this study consisted of 75 schizophrenia patients and 74 healthy individuals (control group). The Positive and Negative Syndrome Scale was used to collect data from the patient group. Complete blood count parameters and lipid profile were analyzed in all study participants.

Results

The patients with schizophrenia had higher MHR values (15.04 ± 3.31 in schizophrenia patients and 12.62 ± 2.99 in controls; p = 0.001). Monocyte counts and MHR of the schizophrenia patients were significantly higher than the control group. There was a significant and positive correlation between age, body mass index, severity of disease and MHR.

Conclusion

To our knowledge, this study was the first to demonstrate inflammatory markers such as MHR levels in schizophrenia patients. Both monocyte counts and MHR values in schizophrenia patients were higher than the control group. MHR might be an available and useful inflammatory marker to evaluate inflammation in schizophrenia patients.

<p>The Predictive Value of Monocyte Count to High-Density Lipoprotein Cholesterol Ratio in Restenosis After Drug-Eluting Stent Implantation</p>

Background

The clinical value of monocyte count to high-density lipoprotein cholesterol ratio (MHR) in in-stent restenosis (ISR) of patients who have undergone bare metal stent implantation has been studied. However, the predictive value of MHR in ISR for patients who have undergone drug-eluting stent (DES) implantation has not been explored.

Methods

Non-ST segment elevation acute coronary syndrome (NSTE-ACS) patients who had undergone DES implantation and coronary angiography follow-up at the Beijing Shijitan Hospital, Capital Medical University, between January 1, 2008, and December 31, 2018, were retrospectively enrolled. Patients were divided into ISR and non-ISR groups depending on the follow-up coronary angiography results. Relative clinical information was recorded and analyzed. The receiver operating characteristic curve analysis was used to determine the optimum cut-off pre-procedural MHR to predict ISR.

Results

A total of 214 patients were enrolled in our study. The mean period between two coronary angiography procedures was 25.4±9.8 months. Percutaneous coronary intervention due to NSTE myocardial infarction, a bifurcation lesion, increased platelet count, and a high MHR were the independent risk factors in multivariate logistic regression analyses.

Conclusion

Our results indicated that elevated MHR is an independent and useful predictor of ISR in NSTE-ACS patients who have undergone DES implantation.

Evaluation of monocyte to HDL cholesterol ratio and other inflammatory markers in patients with psoriasis

Background

Psoriasis is a chronic systemic inflammatory disease frequently associated with serious comorbidities.

Objectives

To investigate the systemic inflammatory burden in psoriasis and to assess the correlation between traditional and novel inflammatory markers and the severity of the disease.

Methods

This cross-sectional study was conducted on 60 patients with psoriasis vulgaris and 50 healthy volunteers. Data including demographics, Psoriasis Area and Severity Index scores, and laboratory results were analyzed and compared.

Results

Compared with the control group, the psoriatic patients had significantly higher high sensitive C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, leukocyte, neutrophil, neutrophil-to-lymphocyte ratio, monocyte to high density lipoprotein (HDL) cholesterol ratio, and aspartate aminotransferase levels, and significantly lower HDL cholesterol levels (p < 0.05). No significant difference was found in procalcitonin, lymphocyte, monocyte, hemoglobin, red blood cell distribution width, platelet, mean platelet volume, platelet distribution width, lymphocyte-to-monocyte ratio, anti-cyclic citrullinated peptide, glucose, alanine aminotransaminase, blood urea nitrogen, creatinine, triglyceride, total cholesterol, and LDL cholesterol levels between the two groups (p > 0.05). The Psoriasis Area and Severity Index score was positively correlated with high-sensitivity C-reactive protein, serum amyloid A, and monocyte to HDL cholesterol ratio, and negatively correlated with lymphocyte-to-monocyte ratio (p < 0.05).

Study limitations

This was a single-center study with relatively limited numbers of patients and controls.

Conclusions

The data show that high sensitivity C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, neutrophil-to-lymphocyte ratio, and monocyte to HDL cholesterol ratio can be used as markers of systemic inflammation in patients with psoriasis. Moreover, high sensitivity C-reactive protein, serum amyloid A, monocyte to HDL cholesterol ratio and lymphocyte-to-monocyte ratio are closely related to the Psoriasis Area and Severity Index score, and they may be regarded as objective indicators in determining the disease severity.
