ABSTRACT

Resumen El presente es un estudio retrospectivo, observacional, cuantitativo y descriptivo. Se evaluó la utilidad de la proteína C reactiva (PCR), la procalcitonina (PCT) y la relación PCR/PCT como marcadores de riesgo de sepsis, sumados al aclaramiento a las 72 h, como pronóstico de mortalidad y permanencia en unidades de cuidados intensivos (UCI). Se incluyeron 23 pacientes. Se clasificaron según qSOFA y se elaboraron curvas ROC. Se obtuvo un área bajo la curva de 0,79 para PCT. El valor umbral de PCT>0,88 ng/mL predice riesgo de sepsis con 77,78% de sensibilidad y 83,33% de especificidad. Utilizando PCR<31,23 mg/dL se obtuvo como parámetros destacados un 88,89% de sensibilidad y 83,33% de valor predictivo negativo, sin diferencias significativas (Mann-Whitney p<0,05) entre los grupos de sobrevivientes y óbitos y estadía prolongada vs. no prolongada. Se postula PCR como screening y PCT como marcador de riesgo de sepsis.


Abstract This is a retrospective, observational, quantitative and descriptive study. The utility of C reactive protein (CRP), procalcitonin (PCT) and the CRP/PCT ratio as sepsis risk markers was evaluated and these, added to clearance at 72 hours, as predictors of mortality and permanence in intensive care units (ICU). Twenty-three patients were included. They were classified according to qSOFA, and ROC curves were prepared, highlighting an area under the curve of 0.79 for PCT. The threshold value of PCT>0.88 ng/mL predicts the of sepsis with 77.78% sensitivity and 83.33% specificity. Using CRP>31.23 mg/dL, 88.89% sensitivity and 83.33% negative predictive value were obtained as outstanding parameters. No significant differences (Mann-Whitney p<0.05) were found between survivors and dead and prolonged vs. non-prolonged stay groups. CRP is postulated for screening and PCT as a sepsis risk marker.

ABSTRACT

Background: Neonatal sepsis is one of the commonest causes of morbidity and mortality. It is one of the four leading causes of morbidity and mortality in India. The purpose of this study was to evaluate the levels of procalcitonin as a rapid diagnostic test, to identify those with infection as soon as possible, and to classify them into definitive, clinical, or no sepsis. The rise in Procalcitonin levels in the neonate with sepsis is very rapid. Hence, it can be used for the diagnosis of early onset neonatal sepsis. Objectives were to estimate the concentration of Procalcitonin for diagnosis of early onset neonatal sepsis and to compare the Procalcitonin levels amongst 3 categories of neonatal sepsis (definite, clinical and no sepsis).Methods: This is a hospital based analytical prospective study.Results: 104 babies with early onset sepsis were included in the study from the NICU in tertiary health care center. Procalcitonin is positive in 69 (66.35%) and negative in 35 (33.65%). Out of the total 69 neonates with Procalcitonin positive, 42 (60.8%) neonates are preterm and 27 (39.1%) are term neonates. Out of the total 35 neonates with Procalcitonin negative, 24 (68.5%) neonates are preterm and 11 (31.4%) are term neonates. There was no sepsis observed in 57 (54.8%) of cases, clinical sepsis was observed in 34 (32.6%) of cases and definite sepsis was observed in 13 (12.5%). The mean value of level of Procalcitonin in different categories of sepsis as determined from the data is 3.27 ng/ml in cases of No sepsis, 11.79 ng/ml in cases of clinical sepsis and 17.2 ng/ml in cases of definitive sepsis.Conclusions: Procalcitonin has good sensitivity and hence can detect most cases of neonatal sepsis and good negative predictive value. Procalcitonin contributes more significantly to the diagnosis of newborn septicemia when paired with additional testing and helps in identifying the categories of sepsis in neonates.

ABSTRACT

Procalcitonin (PCT), a key hormone regulating calcium homeostasis, has previously shown the potential to differentiate between bacterial and viral infections. However, when we move further into the field of COVID-19 pandemic, an unprecedented question was raised: Can PCT levels increase without bacterial co-infection in SARS-CoV-2 infection? This review systematically searched PubMed, Scopus, and Google Scholar for articles on procalcitonin (PCT) in the context of COVID-19 published from 2019 to 2023. Inclusion criteria focused on relevant articles, excluding non-English publications. Increasing PCT levels were observed in COVID-19 patients, especially in severe cases, often interpreted as evidence of bacterial co-infection. However, the role of PCT in the immune response to SARS-CoV-2 remains unclear. The proposed mechanisms suggest that SARS-CoV-2 can stimulate the production of PCT even in the absence of bacterial co-infection by modulating the interferon (IFN) pathway and reducing the regulation of monocyte function. Furthermore, PCT has implications in antibiotic management, with guidelines recommended to avoid antibiotics in patients with low serum PCT levels. Increased PCT values show associations with the severity of disease, including increased mortality, which further underlines the need for a detailed understanding of the dynamics of the PCT in COVID-19. This review emphasizes the evolving significance of PCT in COVID-19, with elevated PCT levels emerging as a valuable prognostic indicator, aiding in disease severity assessment and management. However, the intricate dynamics of PCT in COVID-19 demand further investigation, particularly in distinguishing viral infection from bacterial co-infection.

ABSTRACT

The use of biomarkers in emergency situations represents a change in modern healthcare. This review examines their impact in emergencies focusing on how they improve the accuracy of diagnoses, provide insights into prognosis and aid in treatment decisions. Notably troponins (I and T) are effective in diagnosing myocardial infarction enabling targeted interventions and risk assessment for cardiovascular emergencies. In cases of sepsis procalcitonin helps distinguish infections and influences decisions about therapy, which is crucial for global efforts against resistance. S100B, a biomarker used in emergencies assists in prioritizing cases of brain injury. To prevent harm, serum markers like creatinine and cystatin C guide interventions for hepatic emergencies. For trauma and hematological emergencies D dimer and lactate provide prognostic information. Ongoing research is exploring biomarkers well as the integration of artificial intelligence offering promising advancements for the future. The clinical significance of biomarkers highlights a commitment to approaches that contribute to the ever-evolving field of emergency medicine and ultimately enhance patient care.

ABSTRACT

@#BACKGROUND: Heatstroke has become a common emergency event in hospitals. Procalcitonin (PCT) is used as a biomarker of infection in the emergency department (ED), but its role in rhabdomyolysis (RM) following exertional heatstroke (EHS) remains unclear. METHODS: A retrospective cohort study enrolled patients with EHS from the intensive care unit (ICU). We collected RM biomarkers, inflammation markers, critical disease scores at admission, 24 h, 48 h, and discharge, and 90-day mortality. Correlation analysis, linear regression and curve fitting were used to identify the relationship between PCT and RM. RESULTS: A total of 162 patients were recruited and divided into RM (n=56) and non-RM (n=106) groups. PCT was positively correlated with myoglobin (Mb), acute hepatic injury, disseminated intravascular coagulation (DIC), Sequential Organ Failure Assessment (SOFA) score, and Acute Physiology and Chronic Health Evaluation II (APACHE II) score, with correlation coefficients of 0.214, 0.237, 0.285, 0.454, and 0.368, respectively (all P<0.05). Interestingly, the results of curve fitting revealed a nonlinear relationship between PCT and RM, and a two-piecewise linear regression model showed that PCT was related to RM with an odds ratio of 1.3 and a cut-off of <4.6 ng/mL. Survival analysis revealed that RM was associated with higher mortality compared to non-RM cases (P=0.0093). CONCLUSION: High serum PCT concentrations are associated with RM after EHS in critically ill patients. Elevated PCT concentrations should be interpreted cautiously in patients with EHS in the ED.

ABSTRACT

Objective:To explore the the evaluation value of stress hyperglycemia ratio (SHR), C-reactive protein (CRP), and serum procalcitonin (PCT) for postoperative infection in patients with open tibiofibular fractures.Methods:This study was a prospective analysis. Patients with open tibiofibular fractures hospitalized in the Department of Orthopaedic Surgery of The Second Hospital of Tangshan and North China University of Science and Technology Affiliated Hospital from January 2018 to January 2023 were collected as the research objects, and a total of 839 cases were assessed for outcome, which were divided into infection group (103 cases) and non-infection group (736 cases) according to whether the selected subjects had postoperative infection. The clinical data of the two groups were analyzed by univariate analysis, and the risk factors of postoperative infection of open fracture of tibia and fibula were analyzed by multivariate Logistic regression, and the receiver operating characteristic (ROC) curve was drawn to analyze the predictive efficacy of SHR, CRP, PCT, and their combined models on adverse outcomes.Results:Univariate analysis showed that the infection group had SHR (1.82±0.31), CRP (92.28±36.07) mg/L, PCT (6.35±1.79) μg/L, the non infection group had (1.05±0.12), (56.35±10.21) mg/L and (2.17±0.41) μg/L, respectively, and there were significant differences between the two groups ( t values were 46.90, 21.60, and 54.17, respectively; all P<0.001). The proportion of albumin (<30 g/L) in the infection group was higher than that in the non-infection group (63.11%(65/103), 37.64%(277/736) (χ 2=24.28, P<0.001), and the two groups had significant differences in the rate of time from injury to operation (the infection group ≥6 h was 71.84%(74/103), <6 h was 28.16%(29/103); the non-infection group ≥6 h was 43.07%(317/736), <6 h was 56.93%(419/736); χ 2=35.37, P<0.001), the rate of Gustilo-Anderson classification (the infection group Ⅰ、Ⅱ was 44.46%(46/103), ⅢA was 33.98%(35/103), ⅢB was 12.62%(13/103), ⅢC was 8.47%(9/103);the non-infection groupⅠ、Ⅱ was 59.10%(435/736), ⅢA was 32.47%(239/736), ⅢB was 5.98%(44/736), ⅢC was 2.45%(18/736); χ 2=20.34, P<0.001) and the rate of postoperative drainage volume (the infection group was 40.60%(48/103),the non-infection group was 58.02%(427/736); χ 2=4.79, P=0.029). Multivariate Logistic regression analysis showed that SHR ( OR=1.871,95% CI 1.621-2.160, P<0.001), CRP ( OR=1.060, 95% CI 1.015-1.107, P=0.009), PCT ( OR=1.497, 95% CI 1.420-1.577, P<0.001) were independent risk factors for postoperative infection in open tibiofibular fractures. Among them, SHR had the highest OR value, which was the strongest factor affecting the outcome of the study. Other independent factors were age ( OR=1.052, 95% CI 1.038-1.066, P<0.001) and Gustilo-Anderson type-ⅢC ( OR=1.875, 95% CI 1.038-2.015, P<0.001). By drawing the ROC curve of SHR, CRP, PCT and their combined model to predict the incidence of postoperative infection in open tibiofibular fractures, the results showed that the combined model had higher diagnostic predictive value than the single application, and its sensitivity and specificity were 86.4% and 70.4%, respectively, which were higher than the sensitivity (78.6%, 77.7%, 75.7%) and specificity (69.2%, 69.3%, 69.6%) of the single assessment. Conclusion:The combined model of SHR, CRP and PCT has a higher predictive value than the single detection, which can provide a better clinical basis for the early diagnosis of postoperative infection in patients with open tibiofibular fractures.

ABSTRACT

Objective:To explore the value of serum procalcitonin (PCT), amylase (AMY), albumin (ALB) and lactate dehydrogenase (LDH) in the clinical diagnosis and evaluation of severe acute pancreatitis (SAP).Methods:A total of 70 patients with acute pancreatitis treated in Yancheng First People′s Hospital from January 1, 2020 to December 31, 2022 were enrolled as pancreatitis group. According to disease severity, they were divided into mild group (22 cases) and severe group (48 cases). A total of 70 controls during the same period were enrolled as control group. The general data of all the objects were collected at enrollment. The levels of plasma PCT, AMY, ALB and LDH were detected. The diagnostic value of the above indexes for SAP and their evaluation value for disease severity were analyzed by receiver operating characteristic (ROC) curves.Results:The levels of serum PCT, AMY and LDH in the pancreatitis group were significantly higher than those in the control group: (3.14 ± 0.67) μg/L vs. (0.82 ± 0.21) μg/L, (602.53 ± 199.47) U/L vs. (99.97 ± 30.85) U/L, (767.24 ± 198.73) U/L vs. (423.61 ± 59.19) U/L, P<0.05; while ALB was significantly lower than that in the control group: (33.47 ± 6.98) g/L vs. (45.79 ± 6.12) g/L, P<0.05. ROC curves analysis showed that area under the curve (AUC) values of PCT, AMY, LDH, ALB and combined detection in the diagnosis of acute pancreatitis were 0.783, 0.792, 0.697, 0.732 and 0.915, respectively. The levels of serum PCT and LDH in the mild group were significantly lower than those in the severe group: (2.76 ± 0.44) μg/L vs. (3.59 ± 0.61) μg/L, (507.06 ± 131.67) U/L vs. (848.95 ± 207.79) U/L, P<0.05; while ALB was significantly higher than that in the severe group: (35.39 ± 4.73) g/L vs. (32.64 ± 5.09) g/L, P<0.05. ROC curves analysis showed that the AUC values of PCT, LDH, ALB and combined detection for evaluating disease severity were 0.668, 0.749, 0.741 and 0.959, respectively. The evaluation value of combined detection was significantly higher than that of single index ( P<0.05). Conclusions:The levels of serum PCT, AMY and LDH are abnormally increased, while ALB level is abnormally decreased in patients with acute pancreatitis, and which all can be applied for clinical diagnosis. PCT, LDH and ALB can be applied for disease evaluation.

ABSTRACT

Objective:To analyze the changes rule of serum procalcitonin (PCT) levels in patients with traumatic brain injury in plateau areas, and to evaluate its value in assessing the severity and prognosis of the patients.Methods:A prospective cohort study was conducted. The patients with traumatic brain injury admitted to the critical care medicine departments of Xining Third People's Hospital (at an altitude of 2 260 metres) and Golmud City People's Hospital (at an altitude of 2 780 metres) from May 2018 to September 2022 were enrolled. According to the Glasgow coma scale (GCS) score at admission, the patients were divided into mild injury group (GCS score 13-15), severe injury group (GCS score 9-12), and critical injury group (GCS score 3-8). All patients received active treatment. Chemiluminescence immunoassay was used to measure the serum PCT levels of patients on the 1st, 3rd, 5th, and 7th day of admission. The Kendall tau-b correlation method was used to analyze the correlation between serum PCT levels at different time points and the severity of the disease. The patients were followed up until October 30, 2022. The prognosis of the patients was collected. The baseline data of patients with different prognosis were compared. The Cox regression method was used to analyze the relationship between baseline data, serum PCT levels at different time points and prognosis. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of serum PCT levels at different time points for death during follow-up.Results:Finally, a total of 120 patients with traumatic brain injury were enrolled, including 52 cases in the mild injury group, 40 cases in the severe injury group, and 28 cases in the critical injury group. The serum PCT levels of patients in the mild injury group showed a continuous downward trend with the prolongation of admission time. The serum PCT levels in the severe injury and critical injury groups reached their peak at 3 days after admission, and were significantly higher than those in the mild injury group (μg/L: 3.53±0.68, 4.47±0.63 vs. 0.40±0.14, both P < 0.05), gradually decreasing thereafter, but still significantly higher than the mild injured group at 7 days. Kendall tau-b correlation analysis showed that there was a significant positive correlation between serum PCT levels on days 1, 3, 5, and 7 of admission and the severity of disease ( r value was 0.801, 0.808, 0.766, 0.528, respectively, all P < 0.01). As of October 30, 2022, 92 out of 120 patients with traumatic brain injury survived and 28 died, with a mortality of 23.33%. Compared with the survival group, the GCS score, serum interleukin-6 (IL-6) levels, white blood cell count (WBC) in peripheral blood, and PCT levels in cerebrospinal fluid at admission in the death group were significantly increased [GCS score: 5.20±0.82 vs. 4.35±0.93, IL-6 (ng/L): 1.63±0.45 vs. 0.95±0.27, blood WBC (×10 9/L): 14.31±2.03 vs. 11.95±1.98, PCT in cerebrospinal fluid (μg/L): 11.30±1.21 vs. 3.02±0.68, all P < 0.01]. The serum PCT levels of patients in the survival group showed a continuous downward trend with prolonged admission time. The serum PCT level in the death group peaked at 3 days after admission and was significantly higher than that in the survival group (μg/L: 4.11±0.62 vs. 0.52±0.13, P < 0.01), gradually decreasing thereafter, but still significantly higher than the survival group at 7 days. Cox regression analysis showed that serum IL-6 levels [hazard ratio ( HR) = 17.347, 95% confidence interval (95% CI) was 5.874-51.232], WBC in peripheral blood ( HR = 1.383, 95% CI was 1.125-1.700), PCT levels in cerebrospinal fluid ( HR = 1.952, 95% CI was 1.535-2.482) at admission and serum PCT levels on admission days 1, 3, 5, and 7 [ HR (95% CI) was 6.776 (1.844-24.906), 1.840 (1.069-3.165), 3.447 (1.284-9.254), and 6.666 (1.214-36.618), respectively] were independent risk factors for death during follow-up in patients with traumatic brain injury (all P < 0.05). ROC curve analysis showed that the AUC of serum PCT levels on days 1, 3, 5, and 7 for predicting death during follow-up in patients with traumatic brain injury was all > 0.8 [AUC (95% CI) was 0.898 (0.821-0.975), 0.800 (0.701-0.899), 0.899 (0.828-0.970), 0.865 (0.773-0.958), respectively], indicating ideal predictive value. The optimal cut-off value for serum PCT level at 3 days of admission was 1.88 μg/L, with the sensitivity of 78.6% and specificity of 88.0% for predicting death during follow-up. Conclusions:Abnormal expression of serum PCT levels in patients with traumatic brain injury on the 3rd day of admission was found. The serum PCT levels greater than 3 μg/L may be related to severe illness. The serum PCT levels greater than 1.88 μg/L can predict the poor prognosis of patients. Dynamic observation of changes in serum PCT levels has good evaluation value for the severity and prognosis of patients with traumatic brain injury in plateau areas.

ABSTRACT

Objective:To explore the clinical significance of negative fluid balance and infection management in the treatment of acute respiratory distress syndrome (ARDS) caused by severe novel coronavirus infection.Methods:A retrospective survey was conducted. Patients with ARDS caused by severe novel coronavirus infection who were hospitalized in the department of critical care medicine of the Third Affiliated Hospital of Gansu University of Chinese Medicine and received non-invasive ventilator assisted ventilation were selected as the research objects. The fluid intake and output of all patients were accurately counted every day, and the fluid intake of the next day was adjusted according to the output of the previous day. According to the fluid negative balance, and whether the hospital infection management measures were complied with during the treatment and inspection of the patients, 45 patients with a negative fluid balance of more than 200 mL/d and strict management of nosocomial infection were taken as the observation group, and 48 patients with a negative fluid balance of less than 200 mL/d and no strict management of nosocomial infection were taken as the control group. The general data, weaning success rate, endotracheal intubation rate, mortality, as well as laboratory indicators such as white blood cell count (WBC), procalcitonin (PCT), C-reactive protein (CRP) after treatment were compared between the two groups.Results:There were no significant differences in gender (male: 51.1% vs. 52.1%), age (years old: 66.31±15.92 vs. 67.50±13.59), acute physiology and chronic health evalution Ⅱ (APACHEⅡ: 18.98±4.81 vs. 18.54±4.35) between the observation group and the control group (all P > 0.05), indicating that the baseline data were balanced and comparable. Compared with the control group, the weaning success rate of the observation group significantly increased [53.3% (24/45) vs. 31.2% (15/48), P = 0.031], endotracheal intubation rate significantly decreased [22.2% (10/45) vs. 43.8% (21/48), P = 0.028], mortality significantly reduced [20.0% (9/45) vs. 41.7% (20/48), P = 0.024], laboratory indicators WBC, PCT and CRP levels were significantly reduced [WBC (×10 9/L): 8.085±4.136 vs. 16.898±7.733, CRP (mg/L): 82.827±52.680 vs. 150.679±74.625, PCT (μg/L): 3.142±2.323 vs. 7.539±5.939, all P < 0.01]. Conclusion:Fluid negative balance and infection management have significant clinical significance in the treatment of severe novel coronavirus infection with ARDS.

ABSTRACT

Objective To investigate the value of emergency physician-led focused assessment with sonography for trauma(FAST)combined with serum C-reactive protein(CRP),procalcitonin(PCT),and interleukin-6(IL-6)testing in predicting the clinical outcome of patients with acute chest and abdominal trauma.Methods Ninety-six patients with acute thoracoabdominal trauma,who had been admitted to the Department of Emergency in our hospital from February 2019 to February 2022,were selected for this study.The patients were grouped according to their clinical outcomes,with the individuals who died after 48 h of treatment classified to the death group(n = 14)and all the others to the survival group(n = 82).The general clinical indicators(sex,age,body mass,trauma type,smoking history,alcohol consumption history,and previous chest and abdominal surgery history),CRAMS scores,inferior vena cava-collapse index(IVC-CI),and serum CRP,PCT,and IL-6 levels at 0,24,and 48 h after admission were compared between the two groups.Logistic regression analysis was used to identify the factors that influence the outcomes of patients with acute thoracoabdominal trauma based on statistically significant differences(P<0.05)between the two groups.Receiver operating characteristic(ROC)curves of the IVC-CI combined with serum CRP,PCT,and IL-6 detection were plotted to evaluate the value in predicting clinical outcomes.Results The serum CRP,PCT,and IL-6 levels,CRAMS score,and IVC-CI in the death group were higher than those in the survival group at 0,24,and 48 h after admis-sion(all P<0.001).The serum CRP,PCT,and IL-6 levels in patients in the death group gradually increased from 0,24,and 48 h after admission,and the differences between each time point were statistically significant(all P<0.05).In the patients in the survival group,these serum protein levels increased from 0 to 24 h after admission and peaked at 48 h,and the differences between each time point were statistically significant(all P<0.05).The logistic regression analysis showed that the CRAMS score,IVC-CI,and serum CRP,PCT,and IL-6 levels were risk factors affecting the outcome of patients with acute chest and abdominal trauma(all P<0.05).The area under the ROC curve for the IVC-CI combined with serum CRP,PCT,and IL-6 detection was greater than that for each individual assessment type alone(all P<0.05),and the use of the IVC-CI combined with serum CRP,PCT,and IL-6 detection to predict the clinical outcome of patients with acute chest and abdominal trauma had net clinical benefit.Conclusion The IVC-CI and serum CRP,PCT,and IL-6 levels were associ-ated with the clinical outcomes of patients with acute thoracoabdominal trauma.Therefore,emergency physician-led bedside ultrasound FAST combined with 48 h serum CRP,PCT,and IL-6 testing has good value for predicting the clinical outcomes of patients with acute chest and abdominal trauma.

ABSTRACT

Abstract Objective: This study investigated the effects of N-Acetylcysteine (NAC) combined with Ambroxol Hydrochloride (AH) on clinical symptoms, C-Reactive Protein (CRP), and Procalcitonin (PCT) levels in children with pneumonia. Methods: A total of 98 children with pneumonia were assigned to the control group and observation group by random number table method. NAC was administered to the observation group and AH was given to the control group. The therapeutic effect was observed, the disappearance time of clinical symptoms and levels of inflammatory factors, lung function parameters, blood gas analysis parameters, and immunoglobulin were measured. The incidence of adverse reactions was statistically analyzed. Results: A higher effective rate was observed in the observation group than in the control group (p < 0.05). Antipyretic time, cough disappearance time, and lung rale disappearance time in the observation group were shorter than those in the control group (p < 0.05). After treatment, CRP and PCT were lower (p < 0.05), FVC, FEV1, and FEV1/FVC were higher, PaCO2 was lower, PaO2 and SaO2 were higher, and IgA, IgG, IgM, and C3 were higher in the observation group than those in the control group (p < 0.05). The incidence of adverse reactions between the two groups was not significantly different (p > 0.05). Conclusion: NAC combined with AH is effective in the treatment of pediatric pneumonia by effectively alleviating clinical symptoms, reducing inflammatory factors, and improving lung function and immune function.

ABSTRACT

SUMMARY OBJECTIVE: The objective of this study was to evaluate the impact of the implementation of a bundle of interventions through a "Program for Antibiotic Management and Nosocomial Infection Prevention" in the intensive care unit on antibiotic and devices use and healthcare-associated infections. METHODS: This was a quasi-experimental study of consecutive series of cases in periods before and after the establishment of protocols and checklists for the use of antibiotics as well as other measures to prevent healthcare-associated infection as part of a quality improvement program. Antimicrobial consumption was assessed by the defined daily dose. RESULTS: A total of 1,056 and 1,323 admissions in the pre-intervention and post-intervention phases, respectively, were evaluated. The defined daily dose per 100 patient-day decreased from 89±8 to 77±11 (p=0.100), with a decrease in carbapenems, glycopeptides, polymyxins, penicillins, and cephalosporins. The rates of ventilator and central venous catheter use decreased from 52.8 to 44.1% and from 76 to 70%, respectively. The rates of healthcare-associated infection decreased from 19.2 to 15.5%. CONCLUSION: Quality improvement actions focused primarily on antimicrobial management and prevention of healthcare-associated infection are feasible and have the potential to decrease antibiotic use and healthcare-associated infection rates.

ABSTRACT

Background: India has experienced an unprecedented heave of mucormycosis (MCR) cases during second wave of COVID-19. Possible mechanisms may involve immune and inflammatory processes. The aim of the study is to estimate the role of inflammatory markers for triaging patients of COVID-19 associated rhino-orbital-cerebral mucormycosis (CAROCM) at tertiary care hospital in north India. Methods: A retrospective observational study was conducted between September 2021 to December 2021, at Government medical college and hospital, Patiala (Pb), 83 CAROCM patients admitted in ENT department were evaluated for serum ferritin, D-dimer and PCT. Results: The median age of the patients was 50 years. The number of male patients were 45 and female patients were 38. Based upon the medical history and associated comorbidities involved, 83 CAROCM patients were divided into three groups. 43 diabetic patients in group I, 33 patients with multiple risk factors in group II and 7 patients with no comorbidity in group III. The mean D-dimer levels were 702 ng/ml in group 1, 831ng/ml in group II and 399 ng/ml in group III, and ferritin levels were 522 ng/ml, 711 ng/ml and 426 ng/ml in group I, II and III respectively. Mean PCT levels in group I were 0.27 ng/ml, 1.32 ng/ml in group II and 0.42 ng/ml in group III. Conclusions: Our study concluded that a significant association was observed between levels of inflammatory markers and susceptibility factors. Serum ferritin, D-dimer and procalcitonin, can be used for assessing the severity of infection and decreases the mortality and morbidity in CAROCM patients.
