Hospital outcomes for myocardial infarction are among the clinical conditions influenced by the spread of COVID-19. Patients with COVID-19 frequently experience cardiovascular complications, with challenges encountered in acute management. We assessed clinical presentation, incidence, clinical outcomes and angiographic findings of myocardial infarction in COVID-19 patients.

This  study is a observational retrospective multicenter, medical diagram study was conducted on successive patients hospitalized with diagnosis of Covid-19 and myocardial infarction ,in two large referral hospitals with catheterization equipment and laboratories.COVID-19 infection was confirmed with reverse transcription–polymerase chain reaction assays of a nasopharyngeal sample or pattern of pulmonary parenchymal involvement in lung HRCT (approved by an expert respiratory or infection disease specialist). Data collected included patient demographics, comorbidities, electrocardiogram(ECG) and echocardiography results ,inpatient medication, treatment (fibrinolytic therapy, percutaneous coronary intervention  (PCI) ,coronary artery bypass graft (CABG), vasopressor use, invasive mechanical ventilation),laboratory test results (leucocyte count, C-reactive protein , D dimer, BUN, Cr, and ferritin)and outcome(duration of hospitalization, revascularization success, in-hospital reinfarction and mortality).

The most common comorbidities were hypertension (29, 58%), diabetes mellitus (21, 42%), dyslipidemia (14, 28%) and smoking (5, 10%). Fourteen patients (44.4%) were treated with PCI and 8 (19.5%) patients with fibrinolytic therapy as the initial reperfusion strategy. Revascularization was successful in 62% of patients.  The median CRP level of patients died was 96, which was significantly more than the level (46) in discharged cases (p<0.001). Creatinine levels were also significantly higher in patients who died compared to those who were discharged (p=0.008).

The results of this study demonstrate upper mortality rate in patients with diabetes, kidney injury and high-level CRP, denoting the baseline clinical and laboratory data could be defined as prognostic markers in COVID-19 patients, especially while managing myocardial infarction with concurrent COVID-19 infection.

Current data indicate that serum vitamin D and susceptible C-reactive protein (hs-CRP) levels, both indicative of the inflammatory state, have the potential to predict the onset and severity of chronic pain. Therefore, the objective was to assess the intensity of pain experienced after breast cancer treatment and its relationship with these two parameters.
In this cross-sectional study between 2019 and 2021, 201 patients were enrolled. The McGill Pain Questionnaire was employed to evaluate localized pain intensity at the site six months after the conclusion of cancer treatments. Patients were stratified based on the type of breast surgery, with or without a tissue expander, axillary region surgery, chemotherapy treatment, radiotherapy treatment, serum vitamin D levels, serum hs-CRP levels, and pain intensity. Data analysis was performed using SPSS 21 software with a significance level set at 0.05.
Among the patients, 67.6% (136 individuals) reported mild pain, 31.3% (63 individuals) reported moderate pain, and 1% (2 individuals) reported severe pain. The results of this study demonstrated a positive correlation between high serum hs-CRP levels and increased pain intensity, with serum marker levels being higher in patients experiencing more severe pain compared with those with milder pain. However, no statistically significant association was observed between various serum concentrations of vitamin D and pain intensity (P = 0.12).
Elevated levels of inflammatory factors, such as hs-CRP, are linked to a higher likelihood of developing chronic post-surgical pain.

This study assessed the effects of Aloe verasupplementation on serum inflammatory factors, blood sugar andlipid profiles in hemodialysis patients.

Totally, 50 hemodialysis patients wereallocated randomly to either Aloe vera or placebo groups. TheAloe vera group received 2 Aloe vera capsules daily for 8 weeks(500 mg/day). Serum C-reactive protein (hs- CRP), Fasting bloodglucose (FBS), and lipid profiles levels were evaluated at thebaseline and the end of the eighth week.

Aloe vera supplementation for 8 weeks was associatedwith a significant reduction of serum hs- CRP (p=0.004), totalcholesterol (p=0.01), low density lipoprotein (LDL) (p=0.02) levesand increased high density lipoprotein (HDL) (p=0.002)concentration in the hemodialysis patients.

Aloe vera supplementation is beneficial inimprovement of cardiovascular risk factors in hemodialysispatients

 Mucormycosis, commonly known as "Black Fungus," is an angio-invasive fungus and has become a significant concern during the Coronavirus disease 2019 (COVID-19) pandemic. This study aimed to determine the prevalence rate of mucormycosis and related risk factors among COVID-19 patients, making an essential contribution to further understanding this opportunistic disease.

Methods & Materials:

 This descriptive-analytical cross-sectional study was carried out among 276 patients. Patients were divided into two groups according to the presence of mucormycosis. The diagnosis of mucormycosis was established through a combination of clinical symptoms, imaging findings, and microbiological confirmation. The study examined demographic and clinical characteristics of the patients, including age, gender, duration of hospitalization, and laboratory results, such as C-reactive protein (CRP) and blood sugar levels. The statistical analysis was performed using the SPSS Statistics software package (version 26). Statistical significance was set at a P-value of 0.05.

The mean age of patients participating in the study was 59±16 years. Among them, 158 patients (57.2%) were male, and 20 (7.2%) were diagnosed with mucormycosis. The analysis revealed a significant association between mucormycosis presence and various demographic and clinical variables, notably impacting hospitalization duration, blood sugar level, and serum CRP level.

Findings from our study indicate that elevated CRP and blood sugar levels, as well as prolonged hospitalization, are significant risk factors for mucormycosis in the patients.

 Hemodialysis (HD) is the treatment of end-stage renal disease (ESRD), which leads to increased inflammation and mortality. This study aimed to investigate the relationship of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with high sensitivity C-reactive protein (hs-CRP) levels to predict inflammatory conditions in HD patients.

 A total of 100 eligible maintenance HD patients referred to 22 Bahman and 17 Shahrivar hospitals in Mashhad were enrolled in this cross-sectional study. We collected demographic and clinical data, as well as values of inflammatory markers such as NLR, PLR, and hs-CRP, from the patient’s medical records.

 Forty-six of the patients were female. The mean age of the patients was 37.96±10.29 years, and the mean duration of HD was 54.32±50 months. The mean hs-CRP levels, NLR, and PLR were 6.08±5.70 mg/L, 2.79±1.18, and 125.80±57.14, respectively. The results showed a statistically significant and direct relationship between PLR and hs-CRP levels (P=0.01). There was no correlation between NLR and hs-CRP levels (P=0.8). Additionally, PLR was inversely correlated with hs-CRP in hypertensive patients (r=-0.283, P=0.04), female patients (r=0.3, P=0.04), and patients with HD duration of less than five years (r=0.3, P=0.001).

 Based on these findings, the PLR is a useful inflammatory marker in HD patients with ESRD that correlates with hs-CRP levels. We recommend further investigations to establish its accuracy in clinical care.

Influenza mainly involves the pulmonary system, but may cause damage to other organs like liver, kidneys, and bone marrow. It is essential to identify changes in the laboratory markers indicating inflammation and hepatic injury; and changes in white blood cell count in patients with flu. This study aimed to evaluate these laboratory markers and compare them in children and adults.

This retrospective study was performed in three university hospitals in Qazvin, Iran. Clinically available laboratory biomarkers including some inflammatory markers (e.g. CRP and ESR) , marker of hepatic injury (AST, ALT, ALP, billirubin, prothrombin time), and white blood cell count of 435 definite inflenza patients with positive influenza RT-PCR in 2018 and 2019 were collected from their medical records. The results were classified based on age (over 14 years of age in adults) and the normal range reported by the performing laboratory. Using SPSS software 25, data were analyzed by chi-square and pearson correlation coefficient test. P<0.05 was considered significant.

Leukocytosis was observed in 22.5% of adults and 1.0% of children, and the difference between the two groups was significant (p<0.001). ESR was increased in 91.6% of children and 86.9% of adults;CRP was elevated in 34.7% of adults while 80.5% of children showed elevation (p<0.001). The duration of hospital stay was significantly correlated with ESR (p<0.001, r= 0.177), and CRP (p= 0.002, r= 0.163).The increase in ALT was detected in 32.1% of adults versus 10.0% of children and AST in 38.6% of adults versus 10.0% of children. This increase in both liver enzymes was greater in adults compared with children (p<0.044 and p<0.013, respectively). 42.4% of adults, showed increased prothrombin time.

Leukocytosis, CRP elevation and increase in liver enzymes during influenza seems to be more pronounced in adults than in children. The results also showed a significant relationship between a hospital stay and the level of ESR and CRP.

It has been known for centuries that plants and plant-derived chemicals are useful in treating diseases, with Aloe vera being one of the biologically active plants. A significant role is played by the C-reactive protein (CRP) in many inflammatory conditions, while leukocytes play an integral role in the response of the immune system to infectious diseases.

This study explored the potential anti-inflammatory effects of Aloe vera methanolic extract on the total white blood cell (TWBC) count and CRP levels in Wistar rats received formalin.

A total of 25 Wistar rats were divided into five groups (A to E), with group A serving as the control and the other groups receiving formalin to induce inflammation, followed by increasing doses of Aloe vera extract. The CRP level was measured using an enzyme-linked immunosorbent assay (ELISA) kit, and the TWBC count was determined using a Sysmex haematology autoanalyzer.

Research findings showed that 200 mg of Aloe vera methanolic extract effectively reduced the CRP level (0.056±0.0027) (P=0.04), while 600 mg of the extract significantly increased the TWBC count (13.920±4.757) (P=0.03).

These findings suggest that Aloe vera extract may be an effective natural supplement for improving the immune system function and reducing inflammation in the body. However, further research is needed to fully understand the underlying mechanisms for these effects and to determine the optimal doses and potential side effects.

The use of Securidaca longipedunculata for solving health problems related to immunological disorders is long-standing. The immunomodulatory activity associated with the anti-inflammatory effect of S. longipedunculata has not yet been elucidated by scientific research. The aim of our study is to show that the leaves of S. longipedunculata can solve problems related to immunodeficiency and inflammation.

The phytochemical compounds of the plant were carried out by solubility tests. The anti-inflammatory activity of the plant was evaluated by the chicken egg albumin denaturation inhibition, membrane stabilization, and C-reactive protein (CRP) tests. The 2,2-diphenyl1-picrylhydrazyl, total antioxidant capacity, and inhibition of lipoperoxidation tests were performed to evaluate the antioxidant activity of the plant. Immunosuppression was induced in rats by cyclophosphamide. The immunomodulatory activity of S. longipedunculata was studied by blood count. The lactate dehydrogenase (LDH) titration showed the effect of S. longipedunculata on the energy balance.

The extract contained polyphenols, flavonoids, and tannins. The tests of albumin denaturation inhibition, membrane stabilisation, CRP, total antioxidant capacity, and 2,2-diphenyl-1-picrylhydrazyl revealed that the extract had anti-inflammatory and antioxidant effects. The blood count results revealed that the extract non-significantly increased the number of leukocytes except in the case of neutrophils and monocytes at a dose of 400 mg/kg (P<0.05). The extract also restored the energy balance in the rats according to the LDH results.

This study reveals that the hydro-ethanolic extract of S. longipedunculata leaves has potential immunostimulant and anti-inflammatory effects.

The combined use of methadone and exercise training holds promise for promoting health. This study investigates the impact of resistance and aerobic training in conjunction with methadone consumption on lipid profiles and C-reactive protein (CRP) levels in addicted men.

Ninety addicted men (mean age 36.82 ± 4.32 years) undergoing prison treatment were randomly assigned to six groups (n=15 each): control, narcotics anonymous (NA), aerobic training + methadone, aerobic training + methadone reduction, resistance training + methadone, resistance training + methadone reduction. The 12-week exercise program, conducted thrice weekly, included aerobic training (4-8 sets, 3 minutes each, at 80-90% maximum heart rate on the ergometer bike) and resistance training (12 repetitions, 3 sets, at 70-85% of one repetition maximum). Blood samples collected pre- and post-intervention measured CRP and blood lipids using specialized kits. Data were analyzed with SPSS software, employing multiple analysis of variance (MANOVA) and Tukey's post hoc test (P<0.05).

High-density lipoprotein (HDL) levels significantly increased in trained groups compared to the control (P<0.001). Moreover, trained groups exhibited significant decreases in low-density lipoprotein (LDL), triglycerides, total cholesterol, and CRP compared to the control group (P<0.05). Importantly, aerobic training was more effective than resistance training in improving the studied variables.

Exercise training, particularly aerobic training with methadone ingestion, yields positive effects, including reduced CRP levels and improved lipid profiles in addicted men. Exercise training with methadone reduction may be considered for empowering individuals with addiction issues.

High-sensitivity C-reactive protein (hs-CRP), and homocysteine increase along with inflammation in type 2 diabetes mellitus (T2DM). The antioxidant properties of sumac might affect homocysteine and hs-CRP levels. We aimed to examine the effects of sumac powder (Rhus Coriaria L) on homocysteine and hs-CRP in patients with T2DM.

In a single-blinded, randomized controlled clinical trial, conducted in Ardekan city, Yazd, Iran; 60 patients with T2DM were randomly divided into 2 groups to consume either low fat yogurt alone in the control group or along with 6 (2×3 grams) grams of sumac powder daily in the intervention group, for 3 months. Fasting blood samples were used to analyze the fasting blood sugar (FBS), serum homocysteine, and hs-CRP at the baseline and after 90 days. P values <0.05 were considered statistically significant.

Fifty-eight individuals (intervention n=30, control n=28) with a mean age of 52.30±7.05 years in the intervention, and 51.61±7.07 years in the control group, finished the study. No significant differences were seen for FBS (p=0.94) and homocysteine (p=0.69) changes between the groups; but hs-CRP changes were significantly different between the groups (p=0.03).

Daily consumption of sumac powder for 3 months may not have a reducing effect on FBS and serum homocysteine. This is while sumac may prevent increment of hs-CRP in patients with T2DM.

 Among the serum biomarkers of infectious diseases, calprotectin and heparin-binding protein (HBP) seem to be of clinical and diagnostic value in patients with COVID-19.

 This study aimed to investigate the serum levels of calprotectin, HBP, and some other inflammatory markers in COVID-19 patients.

 In this case-control study, serum samples of 35 outpatients with COVID-19 and 35 healthy individuals were collected, and the levels of calprotectin, HBP, C-reactive protein (CRP), ferritin (FERR), as well as platelet (PLT) and neutrophil (NEU) counts and LDH activity, were determined.

 At first, SARS-CoV2 viral RNA was detected in the pharyngeal swab specimens of COVID-19 patients. Calprotectin, FERR, and CRP levels, LDH activity, and PLT and NEU counts were found to be significantly higher in COVID-19 patients compared with controls (P < 0.05), whereas no statistically significant difference was observed in HBP level (P > 0.05). Serum calprotectin showed a significant correlation with CRP and FERR levels, LDH activity, and NEU count (P < 0.001).

 Our findings showed that an increment in serum calprotectin level, together with increased CRP levels, might be a promising indicator of SARS-CoV2 infection.

People with chronic kidney disease (CKD) experience chronic systemic inflammation. Although a relationship exists between inflammation and renal injury, the association between inflammatory markers and renal disease has not been well-studied. As inflammation may be a trigger or a result of chronic disease, the kidney needs to be investigated to determine whether it is a clearer target for the devastating effects of persistent inflammation. Here, we report the relation of C-reactive protein and mean platelet volume levels with renal functions in chronic kidney disease patients.

This study was an observational retrospective single-center study conducted on the record of CKD patients to detect the outcomes over a median follow-up time of three years. Demographic, clinical, laboratory, medication, and outcome data were obtained from the electronic data records of the hospital. We investigated the multivariable association of plasma levels of C-reactive protein and mean platelet volume with the progression of CKD in the study participants.

Elevated plasma levels of C-reactive protein (r=0.13, P<0.001) and mean platelet volume (r=0.23, P<0.001) were associated with a greater loss of kidney function over time. The presence of diabetes mellitus was detected to be a risk factor for CKD progression (P=0.04). An inverse relationship was detected between sodium and creatinine (P<0.001). In addition, a weak association was detected between uric acid and creatinine (P<0.001). 

Elevated plasma levels of C-reactive protein and mean platelet volume were associated with a decline in the estimated glomerular filtration rate in patients with CKD.

 Infertility affects couples worldwide, with male factors being responsible for half of all cases.

 This study aimed to investigate the relationship between dietary inflammatory index (DII) and levels of C-reactive protein (CRP) in plasma and semen with the quality of semen in infertile males.

 In this cross-sectional study, 88 infertile men referring to Besat hospital, Tehran, Iran from December 2021-November 2022 were enrolled. A detailed questionnaire requesting information, and a 168-item semiquantitative food frequency questionnaire, were completed by participants. A food frequency questionnaire was used to calculate the DII. Additionally, semen and blood samples were collected from each participant for semen analysis and CRP-level assessment. Statistical analyses were performed to explore the association between DII and CRP levels with sperm quality. The correlation between DII and serum/semen CRP, besides assessing nutrients in each DII quartile group, was also explored.

 A significant difference was observed between different DII quartiles considering sperm motility (p = 0.006) and morphology (p = 0.014). Post hoc study revealed a significant difference between the 1st and 2nd quartiles and the 1st and 4th quartiles of DII regarding sperm motility (p = 0.011, and 0.017 respectively) and a significant difference between the 1st and 2nd quartiles of DII considering sperm morphology (p = 0.009). A statistically significant inverse correlation was also observed between DII and sperm motility (p = 0.017). Carbohydrates and β-carotenes were significantly different between the 4 DII quartiles (p = 0.043 and p = 0.026, respectively). Finally, no significant correlation was observed between DII and CRP levels in blood and semen (p > 0.05).

 The findings suggested a notable correlation between DII and semen quality; however, no significant association were observed between DII and CRP levels in blood and semen.

Sepsis is a serious condition that can be fatal and has become more common in recent times. The impact of diastolic dysfunction on the early mortality rate of septic patients has not been extensively researched. This study aimed to assess the accuracy of serum procalcitonin (PCT) levels and diastolic dysfunction in predicting the mortality rate of patients diagnosed with sepsis and admitted to the intensive care unit.

In this cross-sectional study, 40 sepsis patients admitted to the ICU were examined. Their characteristics were meticulously recorded using the APACHE II and SOFA score questionnaires, and only those who met the criteria underwent echocardiography. In order to evaluate the serum levels of PCT, it was required to take 40 ml of venous blood samples from the patients on the first and fifth days of admission.  

Out of 40 patients, the average age was 63±17 years. Of these patients, 23 (57.5%) were discharged, while 17 (42.5%) unfortunately passed away. Results showed a notable correlation between diastolic dysfunction, CRP, SOFA score on days 1 and 2, APACHE II score, and PCT on day 5 (P˂0.05). However, when analyzed using logistic regression, only PCT on day 5 showed a significant association with mortality.

Based on our research, we found that PCT is an essential indicator in predicting the mortality rate of sepsis patients. While there was no significant correlation between diastolic dysfunction and mortality, it should still be considered a critical factor in determining the mortality rate.

Strokes are among the major causes of disabilities worldwide. In recent years, there has been considerable interest in evaluating stroke prognoses.

In this investigation, we studied the association of lymphocyte-monocyte ratio (LMR), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and ESR-CRP ratio (ECR) with 3 months outcomes among those with acute ischemic stroke (AIS).

We carried out the present cross-sectional investigation among AIS patients at an academic hospital in northern Iran (from 2019 to 2021). Within 24 hours after the onset of symptoms, laboratory and clinical data of the patients were obtained. We assessed the results using the modified rankin scale (mRS) 90 days after the initial assessment. Statistical significance for comparing descriptive data was determined as P<0.05.

We entered 341 participants (Mean±SD age: 69.10±13.55 years, 53.1% female) into this investigation. Based on univariate analysis, there were poor correlations between NLR (r=0.361, P<0.001), PLR (r=0.215, P<0.05), CRP (r=0.234, P<0.001), LMR (r=-0.184, P<0.05), and ECR (r=-0.191, P<0.05) and a 3-month mRS. Also, after three months, the NLR, PLR, and CRP values were higher in the patients who died, but the LMR (P<0.001) and ECR (P<0.05) were lower. In multivariate comparison, only ECR was independently higher among the participants who died within 3 months (P<0.05).

In this study, ECR within 24 hours of symptoms onset was related to functional outcomes and mortality at 3-month follow-up. Thus, ECR might provide valuable prognostic information at a relatively low cost.
