Background/PurposeTo evaluate biomarkers as predictors of impending erosion progression.MethodsVariables were measured at baseline and annually up to 5 years in patients with recent-onset polyarthritis treated to zero swollen joints. Erosive status was defined as ≥5 Units in Sharp/van der Heijde Erosion Score; Rapid Erosive Progression (REP) was defined as an increase ≥5 Units in Erosion Scores between consecutive visits. Generalised estimating equations (GEEs) evaluated the effect on REP of positive anticyclic citrullinated peptides (ACPAs) and/or rheumatoid factor (RF), C-reactive protein ˃8.0 mg/L (High-CRP) and 14-3-3η protein ≥0.50 ng/mL (High-14-3-3η), alone and in combinations.ResultsOut of 2155 evaluations in 749 consecutive patients, REP occurred after 186 (8.6%) visits, including 13 (2.2%) in patients recruited since 2010. Only 18/537 (3.4%; 6/411 (1.5%) in non-erosive vs 12/126 (9.5%) in patients already erosive) visits without any positive biomarker were followed by REP; at least one biomarker was positive prior to REP in 168/186 (90.3%) visits. Being positive for all four biomarkers conferred a positive predictive value (PPV) of 30.0% (RR 21.8) in patients non-erosive at the visit versus 35.5% (RR 3.07) in those already erosive. High-14-3-3η increased REP only in visits with High-CRP (eg, RR 2.5 to 3.9 when ACPA also positive) and in patients with non-erosive status (eg, RR from 4.3 to 9.4 when also High-CRP).ConclusionsAdding High-14-3-3η to positive antibodies and CRP improves prediction of impending REP. Although REP is becoming rarer, signatures of biomarkers might help to adapt treatment strategies in at-risk individuals, even those already erosive.

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory breast disease mimicking breast cancer. Limited research has been conducted on the application of serum biomarkers. This study aims to investigate the association of serum biomarkers with disease severity in patients with IGM. From November 2011 to March 2020, medical records of patients with IGM were reviewed. Serum cytokine levels were measured in patients and healthy controls between July 2018 and March 2020. A total of 41 patients with histologically proven IGM were found. Serum interleukin (IL)-6 level was significantly higher in patients with IGM (n = 11) than healthy controls (n = 7). Serum IL-6 and C-reactive protein (CRP) levels were significantly higher in patients with severe disease than mild and moderate disease. Serum IL-6 (Spearman’s ρ = 0.855; p < 0.001) and CRP (Spearman’s ρ = 0.838; p = 0.001) levels were associated with time to resolution. A higher serum CRP level was associated with a longer time to resolution (B = 0.322; p < 0.001) in multiple linear regression analysis. Serum IL-6 and CRP levels can be used as biomarkers for the evaluation of disease severity in IGM. IL-6 may play a crucial role in the immunopathology of IGM.

Background: Neonatal sepsis with its high incidence &grave prognosis, in spite of adequate treatment with modern antibiotics, has been a challenge for all times. Optimal diagnosis and treatment strategies are difficult to define. It is essential to diagnose early with laboratory investigation like serial CRP; so that a feasible, rapid and a relatively economic method to diagnose neonatal sepsis at earliest can be instituted even at basic health care level. hence a study was planned to find out the role of CRP against blood culture in early detection of neonatal sepsis. Aim & Objective: To evaluate Validity of C-Reactive Protein as a screening test in neonatal sepsis. Material and Method: This prospective study was carried out inpaediatric dept of medical college. 100 neonates (≤ 28 days) with suspected neonatal sepsis having a birth weight of ≥ 1000 grams admitted during a period from January 2020 to March 2020 were screened primarily with C-Reactive Protein. Serial level of CRPon the day of admission,2nd ,4th ,6th ,8th& 10th day was compared with the serial blood cultureon the day of admission,8th,15th& 21st day to establish the validity of CRP as a screening test.Data analysis carried out by Percentages, Chi Square test, Sensitivity, Specificity, Positive predictive value, Negative predictive value. Results: Amongst 100neonate 76% were early neonates,65% were low birth weight,CRP was having high sensitivity & specificity(78.57%,76.74% respectively). ROC analysis showed AUC 0.8 with p<0.001.Conclusion: CRP is a good screening test & establishes its validity in diagnosing suspected sepsis.

Objectives: The roles of procalcitonin (PCT) and C-reactive protein (CRP) in febrile cancer patients is currently unclear. Our aim was to assess these in febrile patients with solid tumors and to identify cut-off values for ruling out infection.Methods: We retrospectively evaluated patients with solid tumors admitted to hospital due to fever. They were divided into those with Fever with microbiologically documented infection (FMDI), Fever with clinically documented infection (FCDI) and Tumor-related fever (TRF). PCT and CRP levels were compared. Receiver-operating curves were plotted to define the best cut-off values for discriminating between infection-related and cancer-related fever.Results: Between January 2015 to November 2018, 131 patients were recorded (mean age 68 years, 67% male, 86% with metastasis). Patients with FMDI or FCDI had significantly higher baseline levels of PCT and lower CRP/PCT than those with TRF. A PCT cut-off value of 0.52 ng/mL for discriminating between infection and cancer-associated fever yielded 75% sensitivity, 55% specificity, 77% positive predictive value (PPV), and 52% negative predictive value (NPV). A CRP/PCT ratio with a cut-off value of 95 showed 56% sensitivity, 70% specificity, 79% NPV, and 44% PPV.Discussion: PCT is a sensitive marker of sepsis or localized infection in patients with solid tumors, but its specificity is poor. The CRP/PCT ratio improves specificity, thus providing a reliable means of ruling out infection for values above 95.

Purpose Obesity is associated with a higher risk of breast cancer mortality. The gold standard approach to weight loss is in-person counseling, but telephone counseling may be more feasible. We examined the effect of in-person versus telephone weight loss counseling versus usual care on 6-month changes in body composition, physical activity, diet, and serum biomarkers. Methods One hundred breast cancer survivors with a body mass index ≥ 25 kg/m2 were randomly assigned to in-person counseling (n = 33), telephone counseling (n = 34), or usual care (UC) (n = 33). In-person and telephone counseling included 11 30-minute counseling sessions over 6 months. These focused on reducing caloric intake, increasing physical activity, and behavioral therapy. Body composition, physical activity, diet, and serum biomarkers were measured at baseline and 6 months. Results The mean age of participants was 59 ± 7.5 years old, with a mean BMI of 33.1 ± 6.6 kg/m2, and the mean time from diagnosis was 2.9 ± 2.1 years. Fifty-one percent of the participants had stage I breast cancer. Average 6-month weight loss was 6.4%, 5.4%, and 2.0% for in-person, telephone, and UC groups, respectively (P = .004, P = .009, and P = .46 comparing in-person with UC, telephone with UC, and in-person with telephone, respectively). A significant 30% decrease in C-reactive protein levels was observed among women randomly assigned to the combined weight loss intervention groups compared with a 1% decrease among women randomly assigned to UC (P = .05). Conclusion Both in-person and telephone counseling were effective weight loss strategies, with favorable effects on C-reactive protein levels. Our findings may help guide the incorporation of weight loss counseling into breast cancer treatment and care.

Background: Appendicectomy for suspected acute appendicitis is a common procedure. The rate of normal appendices unnecessarily removed remains high despite several techniques and investigations used to improve the diagnostic accuracy. This study emphasizes the value of C reactive protein (CRP) in three groups of patients operated for clinical suspicion of acute appendicitis with different finding at appendicectomy namely an un-inflamed appendix, uncomplicated acute appendicitis or complicated acute appendicitis.Methods: This prospective study was performed on 100 consecutive patients who were operated on for treatment of acute appendicitis in KVG medical college and hospital between 01 August 2019 to 01 February 2021. Clinically proven by a surgeon, patients underwent appendicectomy. Serum CRP results of all patients were determined. Sensitivity, specificity, positive predictive value and negative predictive value were calculated. Statistical analysis will be made using descriptive statistic and SPSS version 21 was used for analysis.Results: The percentage of negative laparotomies was 13% and surgeon ‘s clinical suspicion was true in 87%. Preoperative CRP values were false negative in 21 patients with appendicitis and false positive in 2 patients with normal appendix. The difference of true and false results between CRP tests and surgeon’s diagnosis was statistically significant (p=0.001). Present study revealed, sensitivity=76%, specificity=87.5%, positive predictive value=96% and negative predictive value=41%.Conclusions: Serum C reactive protein when elevated supports the surgeon’s clinical diagnosis of acute appendicitis. It can be used frequently to diagnosis the acute appendicitis, so that the complication rate and negative laparotomies can be avoided.
