The utility of erythrocyte sedimentation rate, C-reactive protein, and procalcitonin in detecting infections in patients with systemic lupus erythematosus: A systematic review

We conducted a systematic review with metanalysis to investigate the utility of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and procalcitonin (PCT) in diagnosing infections in hospitalized patients with SLE. We searched Medline, Embase, Web of Science, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL) with a search strategy developed by a medical librarian. We included retrospective, cross-sectional, case-control, and prospective studies in our analysis. We used the Quality Assessment of Diagnostic Studies (QUADAS-2) to assess for bias and applicability. We obtained mean differences, sensitivities, and specificities in our analysis. We included 26 studies in our analysis. Most studies had an unclear or high risk of bias and our results were widely heterogenous. For the diagnosis of infections, the CRP had a pooled sensitivity of 0.75 (95%CI 0.57-0.94) and specificity of 0.72 (0.59-0.85), PCT had a pooled sensitivity of 0.68 (95% CI 0.0.59-0.77) and specificity of 0.75 (0.59-0.90), and for ESR pooled estimates were not calculated but sensitivity ranged from 50 to 69.8 and specificity from 38.5 to 55.6. Modifying cut-offs improved sensitivities and specificities. The ESR, CRP, and PCT mean differences were all greater in infection groups versus non-infection (10.1, 95% CI 3.2-17.0; 46.8, 95% CI 36.5-57.0; 0.53, 95% CI 0.26-0.80; respectively). Poor sensitivities and specificities were observed for the evaluated biomarkers with substantial heterogeneity in the cut-offs used to determine infection. Although mean biomarker values were increased in the infection group compared with the non-infection, our findings do not support the widespread use of ESR, CRP, or PCT in diagnosing infection in hospitalized patients with SLE due to increased heterogeneity and risk of bias. Further investigation is needed.

The prognostic significance of erythrocyte sedimentation rate in COVID-19.

There are limited data about the significance of erythrocyte sedimentation rate as a single prognostic parameter for the prognosis and mortality of COVID-19. This study aimed to investigate the diagnostic utility of erythrocyte sedimentation rate as a prognostic factor for the disease severity and mortality in patients with COVID-19. A total of 148 consecutive patients with a confirmed diagnosis of COVID-19 and hospitalized at the intensive care unit or non-the intensive care unit were included in the study. The patients were allocated to groups as severe/critical disease versus nonsevere disease and survivors and nonsurvivors. The prognostic role and predictable values of erythrocyte sedimentation rate were analyzed. Erythrocyte sedimentation rate was found to be higher among patients with severe/critical disease compared to those with nonsevere disease (p<0.001) and among nonsurvivors compared to survivors (p<0.001). The logistic regression analysis showed that erythrocyte sedimentation rate was an independent parameter for predicting disease severity and mortality. The role of erythrocyte sedimentation rate in the assessment of severity and mortality in patients with COVID-19 was analyzed using the receiver operating characteristic curve and was found to be significant in both. The analyses suggested that the optimum erythrocyte sedimentation rate cutoff point for disease severity and mortality were 52.5 mm/h with 65.5% sensitivity and 76.3% specificity and 56.5 mm/h with 66.7% sensitivity and 72.5% specificity. Our results suggest that erythrocyte sedimentation rate was an independent prognostic factor for severity and mortality in patients with COVID-19.

Clinical and laboratory prognosticators of atrophic papulosis (Degos disease): a systematic review

BackgroundDegos disease is a rare vascular disorder with a cutaneous-limited form, benign atrophic papulosis (BAP), and a systemic variant, malignant atrophic papulosis (MAP). Despite the poor prognosis of MAP, no study has established features associated with systemic disease.ObjectivesThe aims of this systematic review were to: (1) summarize clinical features and treatments implemented for patients with MAP and BAP (2) identify clinical and laboratory factors associated with the development of MAP, compared to BAP.MethodsWe systematically searched MEDLINE and Embase from inception to April 2020. Demographic and clinical features of Degos patients were presented descriptively; multivariable logistic regression was performed to identify associations with MAP.ResultsWe identified 99 case studies, comprising 105 patients. MAP (64%) had a 2.15 year median survival time from cutaneous onset, most often with gastrointestinal or central nervous system involvement. We found that elevations in either of erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) were associated with systemic involvement (OR 2.27, p = 0.023). Degos secondary to an autoimmune connective tissue disease was found to be inversely associated with MAP (OR 0.08, p = 0.048).ConclusionsElevated ESR or CRP is associated with MAP and may be a predictor of systemic involvement for patients with Degos disease. In addition, secondary Degos disease is associated with a favourable prognosis. Clinicians should be aware of the differences between primary and secondary Degos and the utility of ESR or CRP in identifying disease evolution to systemic involvement. The utility of ESR and CRP to identify systemic involvement should be further explored.

Sensitivity and Specificity of Serum and Synovial Fluid Markers in Diagnosis of Infection in Head-Neck Taper Corrosion of Metal-On-Polyethylene Total Hip Arthroplasty

BackgroundThe accurate diagnosis of periprosthetic joint infection (PJI) in the setting of adverse local tissue reactions in patients with metal-on-polyethylene (MoP) total hip arthroplasty (THA) secondary to head-neck taper junction corrosion is challenging as it frequently has the appearance of purulence. The aim of this study is to evaluate the utility of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and synovial fluid markers in diagnosing PJI in failed MoP THA due to head-neck taper corrosion. MethodsA total of 89 consecutive patients with MoP THA with head-neck taper corrosion in 2 groups was evaluated: (1) infection group (n = 11) and (2) noninfection group (n = 78). All patients had highly crossed polyethylene with cobalt chromium femoral heads and had preoperative synovial fluid aspiration. In addition, serum cobalt and chromium levels were analyzed. ResultsThe optimal cutoff value for synovial white blood cell was 2144 with 93% sensitivity and 84% specificity. Neutrophil count optimal cutoff value was 82% with 93% sensitivity and 82% specificity. Receiver operating characteristic analysis of ESR and CRP determined optimal cutoff at 57 mm/h and 35 mg/L with 57% sensitivity and 94% specificity and 93% sensitivity and 76% specificity, respectively. There were no significant differences in metal ion levels between the infected and noninfected groups. ConclusionThe results of this study suggest that ESR and CRP are useful in excluding PJI, whereas both synovial white blood cell count and neutrophil percentage in hip aspirate are useful markers for diagnosing infection in MoP THA patients with head-neck taper corrosion associated adverse local tissue reaction.

Diagnostic Utility of Erythrocyte Sedimentation Rate and C-Reactive Protein in Osteomyelitis of the Foot in Persons Without Diabetes

The aim of the study was to assess the diagnostic value of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels in differentiating foot osteomyelitis (OM) from soft tissue infection (STI) in persons without diabetes. We evaluated 102 patients in a retrospective cohort study of nondiabetic patients admitted to our institution with OM (n = 51) and with STI (n = 51). Patient diagnosis was determined through bone culture and/or histopathology for OM and magnetic resonance scan and/or single-photon emission computed tomography for STI. Cutoffs for ESR and CRP to predict OM as identified by receiver operating characteristic were 45.5 mm/h and 3.45 mg/dL, respectively. The ESR cutoff demonstrated a sensitivity and specificity of 49% and 79%, while the values for CRP were 45% and 71%, respectively. The combined sensitivity and specificity for ESR and CRP were 33% and 84%. The positive and negative predictive values were 68% and 60% for ESR and 61% and 56% for CRP, respectively. In conclusion, ESR and CRP demonstrate poor sensitivity and specificity for detecting OM in the nondiabetic foot. These markers have little diagnostic utility in the nondiabetic foot.

Utility of erythrocyte sedimentation rate for a predictor of necrotizing vasculitis: clinicopathological study of biopsy proven vasculitis neuropathy

Background: Vasculitis neuropathy is an emergency disease of peripheral nervous system.

Utility of Erythrocyte Sedimentation Rate and C-Reactive Protein for the Diagnosis of Giant Cell Arteritis

To evaluate the utility of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) for the diagnosis of giant cell arteritis (GCA) and to determine the frequency of normal ESR and CRP at diagnosis of GCA. All patients undergoing temporal artery biopsy (TAB) between 2000 and 2008 were identified. Only subjects with both ESR and CRP at the time of TAB were included. The medical records of all patients were reviewed. We included 764 patients (65% women), mean age 72.7 (±9.27) years, who underwent TAB. Biopsy was consistent with GCA in 177 patients (23%). Elevated CRP and elevated ESR provided a sensitivity of 86.9% and 84.1%, respectively, for a positive TAB. The odds ratio of a concordantly elevated ESR and CRP for positive TAB was 3.06 (95% CI 2.03, 4.62), whereas the odds ratio for concordantly normal ESR and CRP was 0.49 (95% CI 0.29, 0.83). Seven patients (4%) with a positive TAB for GCA had a normal ESR and CRP at diagnosis. Compared with GCA patients with elevated markers of inflammation, a greater proportion of these patients had polymyalgia rheumatica symptoms (P = 0.008), whereas constitutional symptoms, anemia and thrombocytosis, were observed less often (P < 0.05). CRP is a more sensitive marker than ESR for a positive TAB that is diagnostic of GCA. There may be clinical utility in obtaining both tests in the evaluation of patients with suspected GCA. A small proportion of patients with GCA may have normal inflammatory markers at diagnosis.

Clinical utility of erythrocyte sedimentation rate and plasma protein analysis in the elderly

The utilization and interpretation of the erythrocyte sedimentation rate in the elderly have been surrounded by controversy and confusion. To improve the understanding of the erythrocyte sedimentation rate and its determinants in the aged, a defined population of 111 ambulatory, retirement-home residents underwent thorough clinical and laboratory evaluation. Westergren erythrocyte sedimentation rate, Wintrobe erythrocyte sedimentation rate, and plasma viscosity measurements were all significantly correlated with one another as well as with plasma proteins, particularly fibrinogen and globulins. Age per se had no influence on the erythrocyte sedimentation rate in the study population. On the basis of standard upper limits of normal for younger populations, the Wintrobe sedimentation rate was most commonly abnormal and plasma viscosity least commonly abnormal. The “normal” upper limit of 20 mm/hour for Westergren sedimentation rate was also the optimal limit of normal by receiver operating characteristic analysis of the study population. Although the sensitivity of the Westergren sedimentation rate for the presence of an inflammatory condition or monoclonal gammopathy was only 0.55, the specificity was 0.96, and the positive predictive value of an elevated erythrocyte sedimentation rate being associated with a clinical disorder was 0.93. The enhanced clinical utility of the erythrocyte sedimentation rate in this population compared with other elderly populations may be due to a low prevalence of anemia and hypoalbuminemia. In such populations, the erythrocyte sedimentation rate may remain a useful clinical test, regardless of patient age.
