Abstract
Purpose Non-puerperal mastitis (NPM) accounts for approximately 4-5% of all benign breast lesions. Ultrasound is the preferred method for screening breast diseases; however, similarities in imaging results can make it challenging to distinguish NPM from invasive ductal carcinoma (IDC). Our objective was to identify convenient and objective hematological markers to distinguish NPM from IDC. Methods We recruited 89 patients with NPM, 88 with IDC, and 86 with fibroadenoma (FA), and compared their laboratory data at the time of admission. LASSO regression, univariate logistic regression, and multivariate logistic regression were used to screen the parameters for construction of diagnostic models. Receiver operating characteristic curves, calibration curves, and decision curves were constructed to evaluate the accuracy of this model. Results We found significant differences in routine laboratory data between patients with NPM and IDC, and these indicators were candidate biomarkers for distinguishing between the two diseases. Additionally, we evaluated the ability of some classic hematological markers reported in previous studies to differentiate between NPM and IDC, and the results showed that these indicators are not ideal biomarkers. Furthermore, through rigorous LASSO and logistic regression, we selected age, white blood cell count, and thrombin time to construct a differential diagnostic model that exhibited a high level of discrimination, with an area under the curve of 0.912 in the training set and with 0.851 in the validation set. Furthermore, using the same selection method, we constructed a differential diagnostic model for NPM and FA, which also demonstrated good performance with an area under the curve of 0.862 in the training set and with 0.854 in the validation set. Both of these two models achieved AUCs higher than the AUCs of models built using machine learning methods such as random forest, decision tree, and SVM in both the training and validation sets. Conclusion Certain laboratory parameters on admission differed significantly between the NPM and IDC groups, and the constructed model was designated as a differential diagnostic marker. Our analysis showed that it has acceptable efficiency in distinguishing NPM from IDC and may be employed as an auxiliary diagnostic tool.

Abstract
Background HBV and HCV infections are a significant public health issue in developing countries with weak healthcare systems, high poverty rates, illiteracy, low HBV immunization coverage, and low public health education. A study assessed the sero epidemiology of HBV antigen, anti- HCV markers, biochemical and heamatological indices of 559 participants in Dambam local government during hepatitis day. A structured questionnaire was administered to assess demographic information and risk factors. Rapid latex immunochromtographic kits were used for HBV, HCV, and HBV Combo serological markers, with positive and negative control included in each batch analysis. Descriptive statistics analysis was conducted on the data. Results The 559 study participants, had a mean age of 35.5+10.9years, majority within the age- group, 18-39years 279(49.04%), female accounted for 291(52.1%) compared to male 268(47.9), educational background, tertiary 244(43.6%), married, 356(68.7%) and student were 254(45.4%). Seroprevalence of HBsAg was 10.7%, serological markers as follows, HbsAb 1.7%, HbeAg 13.3%, HbeAb 60.0% HbcAb 95.0% and Anti-HCV of 3.4%. Gender breakdown(M vs F) of HBV(13.4% vs 8.2%) and HCV(3.0% vs 3.8%). Significant association was observed in the seroprevalence of HBV and HCV with age-group, gender, marital status and occupation(<0.05). No significant difference was observed with the risk factors of HBV and HCV. Biochemical and heamatological indices showed a significant difference between seropositive and negative study participants(<0.05). Conclusion The study's findings affirmed the endemicity of HBV infection and the increasing trend of HCV infection in Bauchi state, posing serious public health concerns. HBV serological markers suggest a low HBV immunization coverage rate and exposure of participants to the viral etiology in the community. Strengthening immunization coverage and population-based surveillance is strategic in the prevention and control of viral hepatitis in Bauchi state.

Abstract
Nonalcoholic fatty liver disease (NAFLD) currently represents one of the most common liver diseases worldwide. Early diagnosis and disease staging is crucial, since it is mainly asymptomatic, but can progress to nonalcoholic steatohepatitis (NASH) or cirrhosis or even lead to the development of hepatocellular carcinoma. Over time, efforts have been put into developing noninvasive diagnostic and staging methods in order to replace the use of a liver biopsy. The noninvasive methods used include imaging techniques that measure liver stiffness and biological markers, with a focus on serum biomarkers. Due to the impressive complexity of the NAFLD's pathophysiology, biomarkers are able to assay different processes involved, such as apoptosis, fibrogenesis, and inflammation, or even address the genetic background and "omics" technologies. This article reviews not only the currently validated noninvasive methods to investigate NAFLD but also the promising results regarding recently discovered biomarkers, including biomarker panels and the combination of the currently validated evaluation methods and serum markers.

Abstract
Purpose To explore whether machine learning models using serological markers can predict the relapse of Ulcerative colitis (UC). Patients and Methods This clinical cohort study included 292 UC patients, and serological markers were obtained when patients were discharged from the hospital. Subsequently, four machine learning models including the random forest (RF) model, the logistic regression model, the decision tree, and the neural network were compared to predict the relapse of UC. A nomogram was constructed, and the performance of these models was evaluated by accuracy, sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC). Results Based on the patients' characteristics and serological markers, we selected the relevant variables associated with relapse and developed a LR model. The novel model including gender, white blood cell count, percentage of leukomonocyte, percentage of monocyte, absolute value of neutrophilic granulocyte, and erythrocyte sedimentation rate was established for predicting the relapse. In addition, the average AUC of the four machine learning models was 0.828, of which the RF model was the best. The AUC of the test group was 0.889, the accuracy was 76.4%, the sensitivity was 78.5%, and the specificity was 76.4%. There were 45 variables in the RF models, and the relative weight coefficients of these variables were determined. Age has the greatest impact on classification results, followed by hemoglobin concentration, white blood cell count, and platelet distribution width. Conclusion Machine learning models based on serological markers had high accuracy in predicting the relapse of UC. The model can be used to noninvasively predict patient outcomes and can be an effective tool for determining personalized treatment plans.

Abstract
Objectives To construct a novel model based on contrast-enhanced ultrasound (CEUS) and serological biomarkers to predict the early recurrence (ER) of primary hepatocellular carcinoma within 2 years after hepatectomy. Methods A total of 466 patients who underwent CEUS and curative resection between 2016.1.1 and 2019.1.1 were retrospectively recruited from one institution. The training and testing cohorts comprised 326 and 140 patients, respectively. Data on general characteristics, CEUS Liver Imaging Reporting and Data System (LI-RADS) parameters, and serological were collected. Univariate analysis and multivariate Cox proportional hazards regression model were used to evaluate the independent prognostic factors for tumor recurrence, and the Contrast-enhanced Ultrasound Serological (CEUSS) model was constructed. Different models were compared using prediction error and time-dependent area under the receiver operating characteristic curve (AUC). The CEUSS model's performances in ER prediction were assessed. Results The baseline data of the training and testing cohorts were equal. LI-RADS category, α-fetoprotein level, tumor maximum diameter, total bilirubin level, starting time, iso-time, and enhancement pattern were independent hazards, and their hazards ratios were 1.417, 1.309, 1.133, 1.036, 0.883, 0.985, and 0.70, respectively. The AUCs of CEUSS, BCLC,TNM, and CNLC were 0.706, 0.641, 0.647, and 0.636, respectively, in the training cohort and 0.680, 0.583, 0.607, and 0.597, respectively, in the testing cohort. The prediction errors of CEUSS, BCLC, TNM, and CNLC were 0.202, 0.205, 0.205, and 0.200, respectively, in the training cohort and 0.204, 0.221, 0.219, and 0.211, respectively, in the testing cohort. Conclusions The CEUSS model can accurately and individually predict ER before surgery and may represent a new tool for individualized treatment.

Abstract
The utilisation of serological surveillance methods for malaria has the potential to identify individuals exposed to Plasmodium vivax, including asymptomatic carriers. However, the application of serosurveillance varies globally, including variations in methodology and transmission context. No systematic review exists describing the advantages and disadvantages of utilising serosurveillance in various settings. Collation and comparison of these results is a necessary first step to standardise and validate the use of serology for the surveillance of P. vivax in specific transmission contexts. A scoping review was performed of P. vivax serosurveillance applications globally. Ninety-four studies were found that met predefined inclusion and exclusion criteria. These studies were examined to determine the advantages and disadvantages of serosurveillance experienced in each study. If studies reported seroprevalence results, this information was also captured. Measurement of antibodies serves as a proxy by which individuals exposed to P. vivax may be indirectly identified, including those with asymptomatic infections, which may be missed by other technologies. Other thematic advantages identified included the ease and simplicity of serological assays compared to both microscopy and molecular diagnostics. Seroprevalence rates varied widely from 0-93%. Methodologies must be validated across various transmission contexts to ensure the applicability and comparability of results. Other thematic disadvantages identified included challenges with species cross-reactivity and determining changes in transmission patterns in both the short- and long-term. Serosurveillance requires further refinement to be fully realised as an actionable tool. Some work has begun in this area, but more is required.

Abstract
Introduction This study is aimed to map the clinical and immunological features of active lupus patients with different disease duration. Methods For clinical phenotype analysis, we enriched eligible medical records with active SLE (SLEDAI-2k≥8) from the Renji Lupus registry, a single-center database of hospitalized SLE patients with standard care, which covered national-wide patients. Patients with repeated hospitalization records in this enrichment were analyzed longitudinally as validation for the cross-sectional study above. Results We enriched a total of 1313 eligible records on active SLE (SLEDAI-2k≥8) for cross-sectional analysis. Stratified into four groups by a 5-year interval of disease duration, these active SLE patients showed a significantly shifting clinical phenotype along with the duration (ascending nephritis, pulmonary hypertension and descending fever, cutaneous symptoms, arthritis, and neuropsychiatric manifestations), especially in stratifications with disease onset age ≤ 45 years old. A longitudinal analysis of 55 patients with repeated hospitalizations for active lupus showed a similar trend. In the cross-sectional study of 222 records with full information on serology and lymphocyte subsets, peripheral B cell proportion, anti-dsDNA antibody, and serum IgG/IgM negatively correlated with duration, while CD8+ T cell proportion was positively correlated (P values, 0.029-4.8×10-17), which were supported by the sensitivity analysis in patient subgroups according to disease onset age and recent treatment. Multivariate linear regression identified duration as the only significant associator with both B cell and CD8+ T cell proportion (P values, 8.9×10-8 and 7.6×10-5, respectively). These duration biased immune phenotypes were highly consistent with the longitudinal observation in 14 patients with repeated hospitalizations. Conclusions Both clinical and immunological features of active SLE are significantly duration biased distributed, which merits further investigations in the evolution of SLE pathogenesis.

Abstract
Lung cancer represents one of the most common neoplasms and the main cause of cancer‑associated death worldwide. Its relationship with different risk factors such as tobacco, which is its main etiological factor, has been clearly established and despite the numerous advances achieved in the diagnosis, treatment and follow‑up of these patients, the life expectancy of these patients is notably limited. Furthermore, its treatment is not exempt from comorbidities and frequently it neither provides optimal control of the disease nor improve the quality of life of these patients. Despite the possibility of performing screening tests in patients at risk, their implementation in daily clinical practice is complex and most of them are diagnosed at an advanced stage of their disease where systemic radiotherapy or chemotherapy treatments slightly improve their prognosis. Lung adenocarcinoma is the most representative type of lung cancer, with specific epidemiological, molecular and clinical features. Thus, a growing number of studies are being conducted to find potential therapeutic targets based on the study of different molecular pathways, improving the outcome for these patients. In addition, a broad spectrum of serological, immunohistochemical and genetic markers are being evaluated for use in the screening and follow‑up of these patients in daily clinical practice, but unlike for other tumors, they are currently not implemented in the early diagnosis of the disease. Therefore, the aim of the present review was to summarize the main advances that have occurred in the development of serological and histological markers and their therapeutic implications in patients diagnosed with lung adenocarcinoma, explaining the limitations that have been observed and analyzing the future perspectives in the clinical management of this disease.

Abstract
Osteosarcoma represents a rare cause of cancer in the general population, accounting for <1% of malignant neoplasms globally. Nonetheless, it represents the main cause of malignant bone neoplasm in children, adolescents and young adults under 20 years of age. It also presents another peak of incidence in people over 50 years of age and is associated with rheumatic diseases. Numerous environmental risk factors, such as bone diseases, genetics and a history of previous neoplasms, have been widely described in the literature, which allows monitoring a certain group of patients. Diagnosis requires numerous imaging tests that make it possible to stratify both the local involvement of the disease and its distant spread, which ominously determines the prognosis. Thanks to various clinical trials, the usefulness of different chemotherapy regimens, radiotherapy and surgical techniques with radical intent has now been demonstrated; these represent improvements in both prognosis and therapeutic approaches. Osteosarcoma patients should be evaluated in reference centres by multidisciplinary committees with extensive experience in proper management. Although numerous genetic and rheumatological diseases and risk factors have been described, the use of serological, genetic or other biomarkers has been limited in clinical practice compared to other neoplasms. This limits both the initial follow-up of these patients and screening in populations at risk. In addition, we cannot forget that the diagnosis is mainly based on the direct biopsy of the lesion and imaging tests, which illustrates the need to study new diagnostic alternatives. Therefore, the purpose of this study is to review the natural history of the disease and describe the main biomarkers, explaining their clinical uses, prognosis and limitations.

Abstract
Purpose Hepatitis B virus (HBV) is one of the most common infectious pathogens worldwide. Various studies found a prevalence of HBV infection among blood donors ranging from 2% to 18%. Hence, this study aimed to provide an updated prevalence of HBsAg and anti-HBcAb among blood donors. Patients and Methods This was a cross-sectional study to investigate the donation records of blood donors in Sana’a, Yemen, over one year (January to December 2019). Eligible blood donors were included in the study. The serum samples of blood donors were tested for HBsAg and anti-HBcAb (IgG & IgM) using the electrochemiluminescence (ECL) and enzyme immunoassay (EIA) techniques. Results A total of 16,367 blood donors were recruited in this study, of whom 14,300 (87.4%) donated only once during this study (single, non-duplicated blood donors), while 2067 (12.6%) were repeated or duplicated. The overall prevalence of HBsAg and anti-HBcAb was 2.4% and 10.8%, respectively. Among single non-duplicated blood donors, HBsAg and Anti-HBcAb were 2.3% and 10.6% and 3.0% and 12.5% for repeated blood donors, respectively. There were statistically significant differences between HBsAg and Anti-HBcAb in terms of donor type and testing techniques. Conclusion The seroprevalence of HBsAg and anti-HBcAb among the blood donors was 2.0% and 10.3%, respectively. The ECL technique is more sensitive, has a lower error rate, and shows an advantage over the manual EIA technique. Duplicated blood donors influence the accuracy of the seroprevalence of HBsAg and anti-HBcAb.

Abstract
The incidence and prevalence of pancreatic adenocarcinoma have increased in recent years. Pancreatic cancer is the seventh leading cause of cancer death, but it is projected to become the second leading cause of cancer-related mortality by 2040. Most patients are diagnosed in an advanced stage of the disease, with very limited 5-year survival. The discovery of different tissue markers has elucidated the underlying pathophysiology of pancreatic adenocarcinoma and allowed stratification of patient risk at different stages and assessment of tumour recurrence. Due to the invasive capacity of this tumour and the absence of screening markers, new immunohistochemical and serological markers may be used as prognostic markers for recurrence and in the study of possible new therapeutic targets because the survival of these patients is low in most cases. The present article reviews the currently used main histopathological and serological markers and discusses the main characteristics of markers under development.

Abstract
BACKGROUND & AIMS The development of accurate non-invasive tests to detect and measure the extent of fibrosis and disease activity in patients with non-alcoholic steatohepatitis (NASH) - the progressive phenotype of non-alcoholic fatty liver disease (NAFLD) - is of great clinical importance. Herein, we aimed to validate the performance of PRO-C3 and ADAPT for the detection of moderate/severe fibrosis within the CENTAUR screening population. METHODS PRO-C3 was assessed in plasma from the screening population of the phase IIb CENTAUR study (NCT02217475) in adults with NASH and liver fibrosis. The relation between PRO-C3 and histologic features of NASH was evaluated, as well as the demographics of patients with high and low levels of PRO-C3. The diagnostic ability of PRO-C3, as a standalone marker or incorporated into ADAPT, to identify patients with F≥2 and NASH was estimated using receiver-operating characteristic analysis and logistic regression models. RESULTS A total of 517 individuals with matched biopsy and PRO-C3 measurements were included. Patients with PRO-C3 levels ≥20.2 ng/ml showed increased levels of insulin, HOMA-IR, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, and platelet count compared to patients with low PRO-C3 (p <0.05). PRO-C3 increased stepwise with increasing liver fibrosis, lobular inflammation, hepatocyte ballooning, steatosis, and NAFLD activity score (p <0.05), and could distinguish between NAFL and NASH (p <0.0001). PRO-C3 was independently associated with fibrosis and NASH when adjusted for clinical confounders. ADAPT outperformed Fibrosis-4, AST-to-platelet ratio index, and AST/ALT ratio as a predictor of advanced fibrosis and NASH (p <0.001). CONCLUSION PRO-C3 was associated with NAFLD activity score and fibrosis. ADAPT outperformed other non-invasive scores for detecting NASH. These data support the use of PRO-C3 and ADAPT as diagnostic tools to identify patients with NASH eligible for inclusion in clinical trials. CLINICAL TRIAL NUMBER NCT02217475 LAY SUMMARY: PRO-C3 is a serological biomarker associated with liver disease activity and fibrosis. Its performance for the detection of disease activity and fibrosis is improved when it is incorporated into the ADAPT score. Herein, we showed that ADAPT was better at selecting patients with non-alcoholic steatohepatitis for inclusion in clinical trials than other non-invasive scores.

Abstract
Pancreatic cancer has a dire prognosis and will represent the second leading cause of cancer death in the next 10 years. The multifactorial approach represents one of the main issues in controlling the extension of this neoplasm. In recent years, the characteristics of the tumor microenvironment, metastasis mechanisms and the relationship between immune system and neoplastic cells have been described, which has made it possible to understand the pathophysiology of pancreatic adenocarcinoma. Currently, there is a failure to provide an effective preventive method or early detection, so patients present with an advanced stage at the time of diagnosis. Despite numerous efforts, little progress has been made in clinical outcome and in improving survival in long term. Therefore, in the recent years, diverse diagnostic tests, treatments and possible approaches have been developed in the fields of radiotherapy, chemotherapy and surgery to find a combination of them that improves life expectancy in patients diagnosed with pancreatic cancer. At the moment, numerous clinical trials are being conducted to evaluate preventive diagnostic procedures such as serological markers or perfecting available imaging tests. On the other hand, implementation of immunotherapy is being studied in a neoplasm that has lagged in the application of this procedure since present possible treatments do not substantially improve quality of life. Therefore, the purpose of our study is to summarize the main progresses that have been made in the diagnosis, treatment and screening of this disease, explaining the limitations that have been observed and analyzing future prospects in the management of this illness.

Abstract
Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths and the fifth most common cancer worldwide. Clinically therapeutic options for HCC are very limited, and the overall survival rate of patients is very low. Therefore, early diagnosis and treatment of HCC have important impact on overall survival of patients. At present, alpha-fetoprotein (AFP) is one of the most widely used serological markers for HCC. Many evidences have shown that as a specific onco-protein, AFP has great research value in the occurrence, development, diagnosis and treatment of HCC. Here, we briefly introduce the molecular mechanism of AFP in the regulation of HCC occurrence and development, and its role in tumor escape from immune surveillance. We focus on the application of AFP as an important HCC target or carcino-embryonic antigen (CEA) in HCC clinical diagnosis and treatment.

Abstract
To evaluate the value of the combination schemes of 10 serological markers in the clinical diagnosis of acute cerebral infarction.The level of total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, high-sensitivity C-reactive protein, homocysteine (HCY), lipoprotein-related phospholipase A2, ischemia-modified albumin, complement C1q, and lipoprotein a were analyzed in 154 patients with acute ischemic cerebral infarction. The optimized diagnostic combination for acute cerebral infarction was explored by calculating the maximum area under the receiver operating characteristic curves (AUC).The levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-sensitivity C-reactive protein, HCY, lipoprotein-related phospholipase A2, ischemia-modified albumin, complement C1q, and lipoprotein a were significantly higher in the patient vs the control group. Moreover, the positive rate of HCY reached 89.9%. The analysis of the receiver operating characteristic curve of each index and their combinations showed that the minimum AUC of HDL-C alone was 0.543, while the maximum AUC of HCY was 0.853. A multiple logistic regression analysis indicated that HDL-C was a slightly significant variate in the diagnosis of acute cerebral infarction.The value of individual serological markers in the diagnosis of acute cerebral infarction was slightly significant, while the combination of the markers significantly improved the efficiency of its diagnosis.

Abstract
Our objective was to track and quantify the natural course of serological markers over the 1st year following spinal cord injury. For that purpose, data on serological markers, demographics, and injury characteristics were extracted from medical records of a clinical trial (Sygen) and an ongoing observational cohort study (Murnau study). The primary outcomes were concentration/levels/amount of commonly collected serological markers at multiple time points. Two-way analysis of variance (ANOVA) and mixed-effects regression techniques were used to account for the longitudinal data and adjust for potential confounders. Trajectories of serological markers contained in both data sources were compared using the slope of progression. Our results show that, at baseline (≤ 2 weeks post-injury), most serological markers were at pathological levels, but returned to normal values over the course of 6-12 months post-injury. The baseline levels and longitudinal trajectories were dependent on injury severity. More complete injuries were associated with more pathological values (e.g., hematocrit, ANOVA test; χ2 = 68.93, df = 3, adjusted p value <0.001, and χ2 = 73.80, df = 3, adjusted p value <0.001, in the Sygen and Murnau studies, respectively). Comparing the two databases revealed some differences in the serological markers, which are likely attributable to differences in study design, sample size, and standard of care. We conclude that because of trauma-induced physiological perturbations, serological markers undergo marked changes over the course of recovery, from initial pathological levels that normalize within a year. The findings from this study are important, as they provide a benchmark for clinical decision making and prospective clinical trials. All results can be interactively explored on the Haemosurveillance web site (https://jutzelec.shinyapps.io/Haemosurveillance/) and GitHub repository (https://github.com/jutzca/Systemic-effects-of-Spinal-Cord-Injury).

Abstract
Hepatitis B virus (HBV) is a leading cause of liver pathology, which has remained a serious public health challenge in spite of the availability of hepatitis B vaccine discovered about 40 years ago. People living with human immunodeficiency virus (PLHIV) are more at risk of hepatic problems as liver complications appear and progresses faster, owing to their immunocompromised status. This study seeks to determine HBV exposure, serological pattern, and HBV susceptibility among PLHIV. One hundred and fifty PLHIV were enrolled for the study. About 5 mL of blood was collected, processed, and tested for markers of hepatitis B virus: HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc. Twenty-eight (18.7%) had at least one serological marker while 122 (81.3%) tested negative to all the markers. The prevalence of HBsAg in this study was 8.7%, anti-HBs prevalence was 10%, while HBeAg was 2.7%, anti-HBe 6.0%, and anti-HBc 6.7%. Higher HBsAg, HBeAg, and anti-HBc prevalence were observed among the male participants with 13.9%, 5.6%, and 13.9%, respectively, while the female participants had more anti-HBs and anti-HBe of 1.8% and 6.1%, respectively. Age group 51-60 years had the highest prevalence of HBsAg (17.7%), HBeAg (11.8%), and anti-HBe (11.8%) while age group 31-40 years had the highest prevalence of anti-HBs (14.8%) and anti-HBe (9.8%). This study revealed the different serologic patterns of HBV infection among PLHIV and that susceptibility to HBV infection among PLHIV is high.

Abstract
Background and aim: The diagnosis of Crohn's disease (CD) is challenging. Ongoing search for biomarkers to facilitate the diagnosis is a worthwhile endeavor. The aim of this study was to explore the role of serological markers in the diagnosis of CD at an inflammatory bowel disease (IBD) referral center.Methods: This was a retrospective study including 196 suspected CD patients. The expression of ASCA-IgG, ASCA-IgA, AYMA-IgG, AYCA-IgA, FI2Y-IgG, and pANCA in the patient's serum was determined by enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence (IF).Results: ASCA was a relatively specific marker for CD (p = 0.0005), but not AYMA-IgG, AYCA-IgA, F12Y-IgG (p = 0.5936, 0.7974, 0.1085, respectively). However, a high sensitivity of 96.77% (95% CI 90.19%-99.83%) was noted for ASCA+/FI2Y+ to identify CD patients among the suspected cases, albeit with low PPV. The more combinations of serological markers, the higher sensitivity, and NPV. No correlation was found between the age of onset or disease location and the expression of ASCA, AYMA, AYCA, FI2Y, or pANCA. There was no significant difference between the expression of ASCA and the disease behavior at diagnosis (p = 0.3307). However, a decreased proportion of AYMA+ CD patients was found in those who received surgery compared with their non-surgical counterparts (p = 0.0488).Conclusions: ASCA was found to be the most accurate serological marker for the differential diagnosis of CD. Combinations of ASCA, AYMA, AYCA, and FI2Y improved diagnostic accuracy of CD.

Abstract
Background Hepatitis B infection is a public health concern globally. HBV can be associated with type II diabetes mellitus, as HBV outbreaks have been observed among diabetics in healthcare facilities. This study evaluates the prevalence of HBV infection among patients with type II diabetes mellitus. Method A total of one hundred and eighty (180) diabetic patients and one‐hundred non‐diabetics (Controls) were recruited for this study. Structured questionnaires were administered to the consented participants to obtain relevant data. Sera samples obtained were screened using the HBsAg ELISA kit; CTK Biotech, Inc, while the 5 panel kit—rapid diagnostic test, was used to assay for serological markers. Questionnaires were used to obtain relevant information and demographic data. Result Overall prevalence of HBV infection among diabetes patients was 13.3%. Breakdown showed 9 (5.0%) seropositivity was obtained among male subjects compared to 15(8.3%) recorded among the females, P = .834; P < .05. Subjects aged 41‐50 years recorded, 7(3.9%) positivity P = .774; P > .05. Educational status of participants showed 22 (12.2%) positivity among subjects with tertiary level of education P = .032; P < .05). Risk factors considered showed that 5(2.8%).seropositive subjects were alcoholic consumers (P value = .9711; P > .05). Result among non‐diabetics (Control) subjects showed (4%) seropositivity among the male subjects compared to (5.0%) seropositivity recorded among the female subjects (P = .739; P > .05). Conclusion There is an indication of higher risk of HBV infection among type 2 diabetic patients when compared to non‐diabetics. There is the need for more research on this area of study, to further validate the association between HBV infection and Diabetes Mellitus.

Abstract
Despite significant advancements in breast cancer (BC) research, clinicians lack robust serological protein markers for accurate diagnostics and tumor stratification. Tumor interstitial fluid (TIF) accumulates aberrantly externalized proteins within the local tumor space, which can potentially gain access to the circulatory system. As such, TIF may represent a valuable starting point for identifying relevant tumor-specific serological biomarkers. The aim of the study was to perform comprehensive proteomic profiling of TIF to identify proteins associated with BC tumor status and subtype. A liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis of 35 TIFs of three main subtypes: luminal (19), Her2 (4), and triple-negative (TNBC) (12) resulted in the identification of > 8800 proteins. Unsupervised hierarchical clustering segregated the TIF proteome into two major clusters, luminal and TNBC/Her2 subgroups. High-grade tumors enriched with tumor infiltrating lymphocytes (TILs) were also stratified from low-grade tumors. A consensus analysis approach, including differential abundance analysis, selection operator regression, and random forest returned a minimal set of 24 proteins associated with BC subtypes, receptor status, and TIL scoring. Among them, a panel of 10 proteins, AGR3, BCAM, CELSR1, MIEN1, NAT1, PIP4K2B, SEC23B, THTPA, TMEM51, and ULBP2, was found to stratify the tumor subtype-specific TIFs. In particular, upregulation of BCAM and CELSR1 differentiates luminal subtypes, while upregulation of MIEN1 differentiates Her2 subtypes. Immunohistochemistry analysis showed a direct correlation between protein abundance in TIFs and intratumor expression levels for all 10 proteins. Sensitivity and specificity were estimated for this protein panel by using an independent, comprehensive breast tumor proteome dataset. The results of this analysis strongly support our data, with eight of the proteins potentially representing biomarkers for stratification of BC subtypes. Five of the most representative proteomics databases currently available were also used to estimate the potential for these selected proteins to serve as putative serological markers.

Abstract
INTRODUCTION The primary aim of the study was to determine the knowledge of dental practitioners regarding HBV serological markers. Second objective was to determine prevalence of occupational exposures to HBV amongst dentists. METHODOLOGY A questionnaire was constructed pertaining to various aspects of HBV serology; validated by an expert panel; and piloted at 49 dentists. A Cronbach-alpha value of 0.7 was attained and thus extensive survey was conducted among dentists in routine practise treating hepatitis B patients at dental teaching hospitals in Peshawar, KP. The data was analysed using SPSS v.22. RESULTS A response rate of 58% (a total of 290 respondents) was attained. All respondents were vaccinated against HBV. Over 50% reported not to follow Standard precautions for every patient. Overall, 20.3% experienced HBV exposure, eight were administered PEP. Fifty-four percent of FYs; 74.5% PGTs and 71.6% of faculty dentists correctly answered: HBsAg to be the 'serological hallmark of HBV infection'; this was the most correctly answered question. Sixty-four percent dentists failed to identify the infectious carrier phase. Over 50% of dentists in each category failed to correctly answer 5/8 of the HBV serology. CONCLUSIONS Over 20% reported HBV occupational exposure but zero transmissions. Majority of dentists did not have correct information on HBV serological profile which may jeopardise cross-infection control. Further education on HBV serological markers and its clinical relevance to dentistry along with stringent adherence to Standard precautions is recommended.

Abstract
Tissue transglutaminase (tTG) and microbial transglutaminase (mTG) cross-link gliadins to form complexes that expose immunogenic neo-epitopes to produce tTG and mTG-neo-epitope antibodies. The aim of this study was to test the diagnostic performance of antibodies against non-complexed and complexed forms of transglutaminases, to correlate their activities to the intestinal damage and to explore age group dependency in celiac disease (CD). A total of 296 children with untreated CD and 215 non-celiac disease controls were checked by in-house enzyme-linked immunosorbent assays detecting immunoglobulin (Ig)A, IgG or combined detection of IgA and IgG (check) against tTG, AESKULISA® tTG New Generation (tTG-neo) and mTG-neo (RUO), IgA and IgG antibodies against deamidated gliadin peptide (DGP) and human IgA anti-endomysium antibodies (EMA) using AESKUSLIDES® EMA. Intestinal pathology was graded according the revised Marsh criteria, and age dependencies of the antibody activities were analysed. Using cut-offs estimated from receiver operating characteristic (ROC) curves, the highest area under curve (AUC) of the TG assays was 0·963 for tTG-neo check, followed by tTG check (0·962) when the diagnosis was based on enteric mucosal histology. tTG-neo check was the most effective to reflect the intestinal abnormalities in CD (r = 0·795, P < 0·0001). High levels of anti-mTG-neo IgG and anti-tTG-neo IgG appeared in the earlier age groups, as compared to anti-tTG IgG (P < 0·001). Considering antibody diagnostic performance based on AUC, enteric damage reflection and predictability at an early age, the anti-neo tTG check was the most effective diagnostic biomarker for pediatric CD. The mTG neo check might represent a new marker for CD screening, diagnosis and predictability.

Abstract
INTRODUCTION The ability to predict risk for poor outcomes in Crohn's disease [CD] would enable early treatment intensification. We aimed to identify children with CD with complications at baseline and throughout the study period who are at risk for surgery 2 years from diagnosis. METHODS Newly diagnosed children with CD were enrolled into a prospective, multicentre inception cohort. Disease characteristics and serological markers were obtained at baseline and week 12 thereafter. Outcome data including disease activity, therapies, complications and need for surgery were collected until the end of 104 weeks. A chi-square automatic interaction detection [CHAID] algorithm was used to develop a prediction model for early surgery. RESULTS Of 285 children enrolled, 31 [10.9%] required surgery within 2 years. Multivariate analysis identified stricturing disease at baseline (odds ratio [OR] 5.26, 95% confidence interval [CI] 2.02-13.67 [p = 0.001]), and Paediatric Crohn's Disease Activity Index [PCDAI] >10 at week 12 (OR 1.06, 95% CI 1.02-1.10 [p = 0.005]) as key predictors for early surgery. CHAID demonstrated that absence of strictures at diagnosis [7.6%], corticosteroid-free remission at week 12 [4.1%] and early immunomodulator therapy [0.8%] were associated with the lowest risk of surgery, while stricturing disease at diagnosis [27.1%, p < 0.001] or elevated PCDAI at week 12 [16.7%, p = 0.014] had an increased risk of surgery at follow-up. Anti-OmpC status further stratified high-risk patients. DISCUSSION A risk algorithm using clinical and serological variables at diagnosis and week 12 can categorize patients into high- and low-risk groups from diagnosis.

Abstract
The most optimal approach to the problem of managing children with autism spectrum disorders (ASD) is a complex one that involves a pediatric gastroenterologist, a nutritionist, a neurologist, a psychiatrist. Currently, there are studies that confirm the effectiveness of diet in the correction of neuropsychiatric status and gastroenterological disorders in ASD. Evidence supporting the therapeutic value of diets is limited and inconclusive. Diet therapy should be used only if food allergy or gluten or casein intolerance is diagnosed. Aim. To study the frequency of detection of markers of gluten and casein intolerance in children with ASD. Material and methods. The study involved 51 children (39 boys and 12 girls) aged 3 to 15 years with a diagnosis of ASD. Among the study participants, 20 children used gluten-free diet and casein-free diet for more than 6 months. The material for the study was venous blood taken from the elbow vein in the morning on an empty stomach. Determination of specific IgG-antibodies to casein and gliadin, IgA-antibodies to deamidized gliadin peptides was carried out by enzyme immunoassay. The level of total IgA to exclude selective deficiency was also determined. Results and discussion. Most children with ASD (79.5%) had increased levels of specific IgG antibodies to casein. The increase in IgG antigliadin antibodies was determined in 19.3% of children who do not follow a gluten-free diet, and antibodies to deamidized gliadin Ig peptides were not detected in any patient. Gluten intolerance in children with ASD is characterized by sensitivity to it and occurs in 40-50%. Conclusion. According to the literature and the results of own studies, some children with ASD have gluten and casein intolerance. Before the appointment of diet therapy for children with ASD, it is necessary to conduct a survey to clarify the nature of intolerance and the choice of optimal tactics of diet therapy.

Abstract
Background: Hepatitis B viral infection is the most common cause of hepatitis, and it leads to serious liver diseases such as cirrhosis and hepatocellular carcinoma. Aim: The aim of the study is to differentiate acute hepatitis B and chronic hepatitis B (CHB) among patients seropositive for hepatitis B surface antigen (HBsAg). Materials and Methods: This study was carried out in the Department of Microbiology, Chettinad Hospital and Research Institute, Kelambakkam, Tamil Nadu, India, for a period of 6 months (January 2018–June 2018). Blood samples were collected from 87 patients for the detection of hepatitis B virus (HBV) serological markers. HBsAg, hepatitis B e antigen (HBeAg), anti-HBc total, anti-HBc IgM, and antibody to hepatitis B surface antigen were screened using the ELISA method. Detailed demographic profile including history of previous hepatitis infection, previous blood transfusion, and other related details were collected and documented using a structured questionnaire. Results: A total of 87 patients were HBsAg seropositive; among them, 55 (63.2%) were male and 32 (36.9%) were female. Based on the serological markers tested, 24 and 63 were suffering from acute and chronic HBV infections, respectively. Among the acute hepatitis B patients, all samples were seropositive for HBsAg, anti-HBc total, and anti-HBc IgM. HBeAg seromarker was found in 15 patients (62.5%). Among the CHB patients, all samples were seropositive for HBsAg and anti-HBc total. HBeAg seromarker was found in 28 patients with 44.4%. Alcohol consumption was the major risk factor for the transmission of HBV infection. Conclusion: An increased sample size and detailed study of high-risk behavior will provide an alarming awareness of their association.

Abstract
Early diagnosis of malaria reduces disease, prevents deaths, and contributes to decreased malaria transmission. The use of specific and sensitive antigens in the execution of serological diagnostics may have an impact on the transmission of the disease. However, many individuals cannot be easily diagnosed by serological tests due to low levels of antibodies in the serum. Using two different Enzyme-Linked Immunosorbent Assay (ELISA) tests (a commercial and an in-house ELISA), a total of 365 serum samples from individuals with a clinical history of malaria were analyzed. From the serum samples analyzed, 192 (53%) samples from the commercial ELISA and 219 (60%) samples from the in-house ELISA presented positive serological reactivity to malaria. The concordance of the samples tested (n = 365) between both ELISAs was of 67% (n = 242), and with the negative control was 100% (n = 17). We demonstrated that the in-house ELISA showed high antigenic reactivity to Plasmodium falciparum antigens when compared with the commercial ELISA. The degree of concordance of both ELISAs suggested the possibility of existence of other P. falciparum antigens present in the crude extract of P. falciparum that are important in the serological response during malaria infection.

Abstract
PURPOSE To assess the etiological significance of herpesviral infection (HVI) in patients with acute idiopathic optic neuritis (ON) using clinical and laboratory monitoring. MATERIAL AND METHODS Clinical and laboratory examinations were conducted for 10 years and were based on the results of etiological monitoring of 79 patients (85 eyes) with acute idiopathic ON in the period of 2005-2015. RESULTS During a complex examination of 79 patients with acute idiopathic ON, various infectious pathogens were diagnosed in 75 people (94.9±2.1%). HVI was clearly dominant (69 patients - 87.3±2.4%). These patients were divided into 3 etiological groups. The first group - 34 people with herpesviral monoinfection; the second group - 15 people with mixed viral-viral infections; the third group - 20 people with mixed viral-bacterial infections. In the general population of patients with acute idiopathic ON associated with HVI, herpes simplex virus-1 is the most frequent (by more than 2.5 times), the infections of Epstein-Barr virus and cytomegalovirus were detected less often (p<0.05). Active current HVI in the general group of patients was diagnosed in 58 patients (84%). At the same time, reactivation of chronic infection (79.7%) was noted to be prevalent, while primary acute HVI was diagnosed rarely (4.3%). The remaining 11 patients (16%) had chronic persistent HVI. CONCLUSION Clinical and laboratory monitoring of HVI in patients with acute idiopathic ON has shown the etiological role of herpesviruses in its development. Based on a complex of serological markers in enzyme-linked immunoassay reactions of blood serum, it was found that in patients with acute idiopathic ON the frequency of herpesviral infection is 87.3±2.4%. The proportion of active (etiologically significant) herpesviral infection is 84% of the total group. The results of the clinical and laboratory studies are of great practical importance for verification of the etiologic diagnosis and selection of adequate etiopathogenetic therapy in patients with acute idiopathic ON associated with HVI.

Abstract
INTRODUCTION Thailand has integrated hepatitis B (HB) vaccination of newborns into the national Expanded Program on Immunization (EPI) in 1992. This has led to a dramatic decrease of HBsAg prevalence in children. However, HB vaccine coverage in remote areas is not well-known. This study aimed to investigate serologic characteristics of hepatitis B virus (HBV) among hill-tribe children in Omkoi District, Chiangmai Province, Thailand. METHODOLOGY This cross-sectional study was conducted on stored samples collected from hill-tribe children attending the primary/secondary school in Omkoi District in December 2014. Sera were tested for HBsAg, anti-HBs and anti-HBc using enzyme immunoassays (MUREX, DiaSorin, Italy). Samples with anti-HBc positive were further assessed for HBV DNA using an in-house HBV DNA semi-nested polymerase chain reaction (PCR) assay. RESULTS Of 210 children evaluated, 4 (1.9%:95% CI 0.5-4.8) were HBsAg-positive. Of the 206 children HBsAg negative, 17 were anti-HBc and anti-HBs positive, 15 anti-HBc positive only, 26 anti-HBs positive only and 148 negative for both anti-HBc and anti-HBs. None of the children with anti-HBc were positive for HBV DNA. CONCLUSIONS A high percentage of children had no markers of HBV protection suggesting that HB vaccine coverage was not optimal in this area. Our results warrant HBV serologic investigations in other remote areas to assess whether HB vaccine coverage needs to be improved and to identify children who should be vaccinated.

Abstract
Introduction: Plasmodium vivax (Pv) and P. knowlesi account together for a considerable share of the global burden of malaria, along with P. falciparum (Pf). However, inaccurate diagnosis and undetectable asymptomatic/submicroscopic malaria infections remain very challenging. Blood-stage antigens involved in either invasion of red blood cells or sequestration/cytoadherence of parasitized erythrocytes have been immunomics-characterized, and are vital for the detection of malaria incidence. Areas covered: We review the recent advances in Plasmodium immunomics to discuss serological markers with potential for specific and sensitive diagnosis of malaria. Insights on alternative use of immunomics to assess malaria prevalence are also highlighted. Finally, we provide practical applications of serological markers as diagnostics, with an emphasis on dot immunogold filtration assay which holds promise for malaria diagnosis and epidemiological surveys. Expert commentary: The approach largely contributes to Pf and Pv research in identifying promising non-orthologous antigens able to detect malaria incidence and to differentiate between past and recent infections. However, further studies to profiling naturally acquired immune responses are expected in order to help discover/validate serological markers of no cross-seroreactivity and guide control interventions. More so, the application of immunomics to knowlesi infections would help validate the recently identified antigens and contribute to the discovery of additional biomarkers of exposure, immunity, or both.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis in the absence of significant alcohol consumption (<40 g/week). The essential metabolic trait is insulin resistance, which is why NAFLD is associated with obesity, diabetes mellitus (DM), hyperlipidemia. Approximately one-quarter of adults with NAFLD present nonalcoholic steatohepatitis (NASH) leading to progressive hepatic fibrosis and finally cirrhosis and hepatocellular carcinoma. If liver biopsy (LB) has traditionally been NAFLD’s gold standard, over the past 15 years, its use has undergone an important transformation. In this review, the role of noninvasive tests (serological markers, imaging techniques) in the NAFLD evaluation is analyzed, starting from the low adherence of patients for LB, the complications of the technique, and the increased cost. LB is the only investigation that distinguishes between simple steatosis and NASH. However, in the medical practice, LB has gained lesser value; it is worth mentioning that NASH represents a small proportion compared to NAFLD. For this reason, most patients only show biopsy steatosis, which has a good prognosis. In addition, judging by the appearance of inflammation markers and fibrosis in the diagnosis technique, the use of LB has become increasingly rare in the definition of NASH.

Abstract
Recent data suggest that severe psoriasis is an independent risk factor for chronic renal disease. In the present study, we investigated the role of related-purine derivatives as predictors of renal dysfunctions in patients with psoriasis. A prospective study was conducted on a group of 45 patients with psoriasis vulgaris and 45 control cases, monitored over a 5-year period. Alterations of renal function, albumin/creatinine ratio (ACR, mg/g) and UA/creatinine ratio (UACR, mg/mg) were determined in spontaneous urine samples. The status of related-purine derivatives was evaluated by quantification of uric acid (UA, mg/dl), adenosine deaminase (ADA, UI/mg protein), xanthine oxidase (XO, UI/mg protein) and 8-hydroxy-deoxy-guanosine levels (8-OHdG, ng/ml) in serum samples. Compared to the controls, in patients with psoriasis there was an increase in related-purine derivatives levels, which was demonstrated by the elevated serum levels of UA (5.1±0.4 vs. 5.4±1.0, P=0.066), ADA (0.14±0.08 vs. 0.29±0.12, P=0.052), XO (0.22±0.11 vs. 0.42±0.21, P=0.011) and 8-OHdG (3.1±0.05 vs. 8.3±4.7, P=0.002). The serum levels of related-purine derivatives were associated with the severity of psoriasis. In addition, there was a link between the serum levels of related-purine derivatives and markers of renal impairment. There were positive correlations between 8-OHdG and ACR (r=0.452, P=0.028) and between ADA, XO, UA, 8-OHdG and UACR (r=0.297 and P=0.032, r=0.301 and P=0.002, r=0.431 and P=0.027, r=0.508 and P=0.002) and negative correlations between UA, 8-OHdG and the estimated glomerular filtration rate (r=-0.301 and P=0.036, r=-0.384 and P=0.002). Thus, severe psoriasis is a risk factor for the development of renal disease.

Abstract
Evaluating progression risk and determining optimal therapy for ulcerative colitis (UC) is challenging as many patients exhibit incomplete responses to treatment. As part of the PROTECT (Predicting Response to Standardized Colitis Therapy) Study, we evaluated the role of the gut microbiome in disease course for 405 pediatric, new-onset, treatment-naive UC patients. Patients were monitored for 1 year upon treatment initiation, and microbial taxonomic composition was analyzed from fecal samples and rectal biopsies. Depletion of core gut microbes and expansion of bacteria typical of the oral cavity were associated with baseline disease severity. Remission and refractory disease were linked to species-specific temporal changes that may be implicative of therapy efficacy, and a pronounced increase in microbiome variability was observed prior to colectomy. Finally, microbial associations with disease-associated serological markers suggest host-microbial interactions in UC. These insights will help improve existing treatments and develop therapeutic approaches guiding optimal medical care.

Abstract
The etiological role of the Epstein-Barr virus (EBV) in the development of an undifferentiated histological variant of nasopharyngeal carcinoma (uNPC) found for the first time in regions with a high incidence of this pathology, the Southern provinces of China and the countries of Southeast Asia, and later in the rest of the world, has served as a basis for the widespread use of EBV serological markers for the diagnosis of this form of tumor. In recent years, the use of a test based on the quantitative determination of the EBV DNA concentration in the blood plasma of uNPC patients for early detection and monitoring of the disease has become widespread in endemic regions. In non-endemic regions, such studies virtually have not been carried out, and moreover, the comparative evaluation of the significance of two viral markers, serological and EBV DNA load in the bloodstream of uNPC patients, for diagnostics and evaluation of the therapeutic effect was not investigated. The aim of this study was to compare the clinical value of two serological markers and plasma EBV DNA load in uNPC patients from non-endemic region (Russia). The obtained results indicate that IgA antibodies to the viral capsid antigen (IgA/VCA) and plasma EBV DNA concentration can be successfully used for the diagnosis of uNPC, while IgG/VCA antibodies have no practical significance as an uNPC marker. In addition, it was found that plasma EBV DNA load is more sensitive marker of uNPC than IgA/VCA titers because DNA copy numbers reflect more accurately the effect of the therapy and the clinical state of patients at the stages of remission or relapse. It was shown for the first time that in the non-endemic region the simultaneous evaluation of IgA/VCA antibody levels and the plasma EBV DNA loads are the most effective markers for the diagnostics of uNPC. However, we believe, that it is more practical to use IgA/VCA antibody levels for uNPC screening, and plasma EBV DNA copies - for monitoring of the disease.

Abstract
OBJECTIVE To describe the prevalence of serological markers in newly diagnosed treatment-naïve pediatric inflammatory bowel disease (IBD), their utility in differentiating Crohn's disease (CD), ulcerative colitis (UC) and symptomatic non-IBD patients and whether serological markers are associated with early TNF blocker treatment. MATERIAL AND METHODS Ninety-six children and adolescents <18 years, 58 with IBD and 38 symptomatic non-IBD controls were included. At diagnosis and after 1-2 years, serological antibodies (anti-Saccharomyces cerevisiae antibodies (ASCA), perinuclear anti-neutrophil cytoplasmic antibody (pANCA), flagellin expressed by Clostridial phylum (anti-CBir1), outer membrane porin of Escherichia coli (anti-OmpC), Pseudomonas fluorescens-associated sequence (anti-I2), CRP, ESR and fecal calprotectin were analyzed. The choice of treatment was made at the discretion of the treating pediatrician. RESULTS Of the IBD patients, 20 (36%) and 26 (47%) were positive for ASCA and pANCA compared to 3(8%), p < .01 and 10 (27%), p = .04 of the controls. Thirteen (72%) of UC patients were pANCA positive, versus 13 (35%) of CD patients (p < .01). None of the UC patients was ASCA positive versus 20 (54%) of CD patients (p < .0001). Compared to conventionally treated patients, the 18 (49%) TNF blocker treated CD patients had higher presence of ASCA (p < .01), lower presence of pANCA (p = .02) and higher levels of fecal calprotectin, CRP and ESR at diagnosis. In multivariate analyses ASCA and pANCA status, but not CRP, ESR or calprotectin, were independently associated with early TNF blocker treatment. CONCLUSIONS ASCA and pANCA status were associated with having IBD and with early TNF blocker treatment in CD.

Abstract
OBJECTIVE To evaluate prospectively serological markers at baseline and during treatment in patients with rheumatoid arthritis (RA) initiating rituximab treatment, following failure of antitumour necrosis factor (TNF)-α therapy. METHODS Patients with RA and healthy control subjects were recruited. Plasma complement (C)3, C4, rheumatoid factor (RF), anticitrullinated protein antibody (ACPA), immunoglobulin (Ig)M, A and G, disease activity scores (DAS) and therapeutic response were recorded at baseline and at 6, 12 and 18 months. RESULTS Patients (n = 35) had significantly higher C3 and C4 levels than controls (n = 30). At 12 months after initiation of rituximab, C3 and C4 levels were significantly lower in patients who responded to treatment, compared with nonresponders. There were direct correlations between C3 levels and DAS at 12 months in the study population as a whole, and between IgM levels and DAS in responding patients after 6, 12 and 18 months' treatment. CONCLUSIONS C3 and IgM levels may represent potentially useful serological markers of disease activity during rituximab treatment in patients with RA.

Abstract
OBJECTIVE The objective of this study is to investigate the occurrence of gastrointestinal (GI) and extraintestinal symptoms in children and adolescents with type 1 diabetes mellitus (DM1) and Down syndrome (DS) and their association with specific antibodies and histopathology of celiac disease (CelD), representing its clinical forms in the iceberg. MATERIAL AND METHODS Cross-sectional study (November 2009-December 2012) conducted at an outpatient care facility in Northeast Brazil including patients [DM1 (n = 111); DS (n = 77)] aged 10 months-18 years old. Measurement of anti-endomysial (EmA) and anti-tissue transglutaminase (anti-tTG) IgA antibodies was performed, as was that of anti-tTG-IgG in the cases with low serum IgA. The patients with antibody positivity were subjected to small intestine biopsy. RESULTS GI symptoms occurred in 53.7% of the sample, extraintestinal symptoms in 4.3%, and antibody positivity in 28.2% (n = 53). Of those who underwent biopsy (n = 40), histopathological findings of CelD were found in 37.5% [DM1 = 5/111 (4.5%), DS = 10/77 (13.0%)]. GI symptoms were associated with antibody positivity, but not with the histopathology. The GI (32.5%), silent (5.0%), and potential (62.5%) forms of disease were detected. CONCLUSIONS The prevalence of GI symptoms was high in groups DM1 and DS, and the occurrence of such symptoms was associated with antibody positivity. The lack of association between the symptoms and histopatholological findings points to the inconsistency of the former as indicators of CelD. Although the GI form predominated among the cases with active CelD, its contribution to the celiac iceberg was smaller compared with the potential form, which determined the large and submerged base of the iceberg representing the high-risk groups investigated.

Abstract
The progression of head and neck squamous cell carcinoma (HNSCC) is stimulated by various angiogenic peptides and growth factors. A correlation between tumor progression and the secretion of various serological mediators in patients with malignant tumors of the head and neck is of major interest for tumor diagnostics, evaluation of the therapy response and it may predict prognosis by specifying the individual tumor biology. Established chemotherapeutic regimes for head and neck tumors usually consist of platinum-based chemotherapeutic drugs and 5-fluorouracil (5-FU). The present pilot study sought to assess the eligibility of seven serological factors as biomarkers for malignant tumors of the head and neck: Platelet-derived growth factor, vascular endothelial growth factor, epidermal growth factor receptor, osteopontin, granulocyte-colony stimulating factor, interleukin-4 (IL-4) and IL-6. The serum levels of each factor in 20 patients receiving concomitant radiochemotherapy with cisplatin or carboplatin and 5-FU with curative intent were determined prior and subsequent to chemotherapy and were compared with 40 healthy controls. Another aim of the pilot study was to investigate whether the serum of patients showed significant differences in the concentrations of the analyzed factors at the start of concomitant radiochemotherapy compared with the controls, whether those markers indicated a neoplastic process and whether concomitant radiochemotherapy with cisplatin or carboplatin and 5-FU induced significant alterations of concentration compared with pre-therapeutic levels. The included patients were histopathologically diagnosed with HNSCC and the average age was 62.3 years. The serum samples of the patients were obtained during the course of regular pre- and post-chemotherapeutic blood draws one week prior to the start of radiochemotherapy and one week following the completion of chemotherapy. The healthy controls were collected from patients of the Sleep Laboratory of the Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital (Mannheim, Germany) without clinical evidence or laboratory signs of inflammation or history of a malignant disease. The average age was 50.3 years. The serological level of each factor was ascertained by enzyme-linked immunosorbent assay in duplicate. Serum levels of IL-4, IL-6 and osteopontin were significantly increased in patients with HNSCC compared with those in chemotherapy-naive healthy controls. IL-4 and osteopontin showed no significant therapy-associated alterations. Notably, IL-6 levels significantly increased post-therapeutically. Using logistic regression with osteopontin and IL-4, an individual risk-profile for random samples was calculated. IL-4, IL-6 and osteopontin appear to be suitable indicators of the neoplastic process as they are significantly increased in HNSCC patients compared with the control group. With the exception of IL-6, whose levels were in fact increased following therapy, a significant therapy-associated alteration of these factors was missing. Therefore, these serological markers failed to predict the therapy response, but they may be valuable as a screening instrument in primary diagnostics.

Abstract
BACKGROUND AND OBJECTIVES In Lao People's Democratic Republic, hepatitis B virus is highly endemic. However, blood donations are only screened for HBsAg, leaving a risk of transmission by HBsAg-negative occult infected donors. Here, we characterized first-time blood donors to assess prevalence of hepatitis B virus infections and occult infected donors. MATERIALS AND METHODS Sera were screened for HBsAg, HBeAg and anti-HBs, anti-HBc and anti-HBe antibodies. Occult HBV infections (OBIs) were assessed in HBsAg-negative sera by PCR, and sera of HBsAg positive and occult infected donors were phylogenetically characterized. RESULTS 9·6% of the donors were HBsAg positive, and 45.5% were positive for at least one of the hepatitis B virus serum markers. More than 40% HBsAg carriers were HBeAg positive, with HBeAg seroconversion occurring around 30 years of age. Furthermore, 10·9% of HBsAg-negative, anti-HBc and/or anti-HBs-positive donors were occult infected with hepatitis B virus. Thus, at least 3·9% of blood donations would potentially be unsafe, but hepatitis B virus DNA copy numbers greatly varied between donors. CONCLUSION In Lao People's Democratic Republic, a sizable proportion of HBsAg-negative and anti-HBc antibody-positive blood donations are potentially DNA positive and infective for hepatitis B.

Abstract
BACKGROUND AND AIMS Delayed or wrong diagnosis in patients with appendicitis can result in perforation and consequently increased morbidity and mortality. Serum bilirubin may be a useful marker for appendiceal perforation. The purpose of this systematic review was to evaluate studies investigating elevated serum bilirubin as a predictor for appendiceal perforation. MATERIAL AND METHODS Medline, Embase, and Cochrane databases were searched for studies evaluating elevated bilirubin in the diagnosis of perforated appendicitis. Study selection criteria included English language papers evaluating serum bilirubin as a marker of appendiceal perforation in humans. A total of 189 abstracts were screened for eligibility, of which five clinical studies were included in this study. RESULTS Bilirubin was significantly higher in patients with appendiceal perforation compared with patients with appendicitis without perforation. Elevated serum bilirubin had a sensitivity ranging from 0.38 to 0.77 and a specificity ranging from 0.70 to 0.87 in predicting appendiceal perforation. CONCLUSIONS Elevated serum bilirubin for determining the risk of perforation in appendicitis has low sensitivity but higher specificity. This measure can therefore be used as a supplement in the diagnostic process.

Abstract
During recent years, a rising incidence of invasive pulmonary aspergillosis (IPA) in non-neutropenic critically ill patients has been reported. Critically ill patients are prone to develop disturbances in immunoregulation during their stay in the ICU, which render them more vulnerable for fungal infections. Risk factors such as chronic obstructive pulmonary disease (COPD), prolonged use of steroids, advanced liver disease, chronic renal replacement therapy, near-drowning and diabetes mellitus have been described. Diagnosis of IPA may be difficult and obtaining histo- or cytopathological demonstration of the fungus in order to meet the gold standard for IPA is not always feasible in these patients. Laboratory markers used as a non-invasive diagnostic tool, such as the galactomannan antigen test (GM), 1,3-beta-glucan, and Aspergillus PCR, show varying results. Antifungal therapy might be considered in patients with persistent pulmonary infection who exhibit risk factors together with positive cultures or sequentially positive GM and Aspergillus PCR in serum, in whom voriconazole is the drug of choice. The benefit of combination antifungal therapy lacks sufficient evidence so far, but this treatment might be considered in patients with breakthrough infections or refractory disease.

Abstract
BACKGROUND Treatment of coeliac disease (CD) requires lifelong adherence to a strict gluten free diet (GFD) which hitherto has consisted of a diet free of wheat, rye, barley, and oats. Recent studies, mainly in adults, have shown that oats are non-toxic to CD patients. In children, only open studies comprising a small number of patients have been performed. AIM To determine if children with CD tolerate oats in their GFD. PATIENTS AND METHODS In this double blind multicentre study involving eight paediatric clinics, 116 children with newly diagnosed CD were randomised to one of two groups: one group was given a standard GFD (GFD-std) and one group was given a GFD with additional wheat free oat products (GFD-oats). The study period was one year. Small bowel biopsy was performed at the beginning and end of the study. Serum IgA antigliadin, antiendomysium, and antitissue transglutaminase antibodies were monitored at 0, 3, 6, and 12 months. RESULTS Ninety three patients completed the study. Median (range) daily oat intake in the GFD-oats group (n = 42) was 15 (5-40) g at the six month control and 15 (0-43) g at the end of the study. All patients were in clinical remission after the study period. The GFD-oats and GFD-std groups did not differ significantly at the end of the study regarding coeliac serology markers or small bowel mucosal architecture, including numbers of intraepithelial lymphocytes. Significantly more children in the youngest age group withdrew. CONCLUSIONS This is the first randomised double blind study showing that the addition of moderate amounts of oats to a GFD does not prevent clinical or small bowel mucosal healing, or humoral immunological downregulation in coeliac children. This is in accordance with the findings of studies in adult coeliacs and indicates that oats, added to the otherwise GFD, can be accepted and tolerated by the majority of children with CD.

Abstract
BACKGROUND Phage displayed random peptide technology has been utilised to identify binding epitopes of antibodies or receptor ligands. AIM To isolates peptides from a phage library which are specifically recognised by antibodies in serum from patients with Crohn's disease (CD). METHODS A phage displayed random peptide library composed of nine amino acids was established and sequentially screened using serum immunogloblin G obtained from CD patients. RESULTS Five different CD specific peptides were isolated from the phage library. No homology in amino acid sequences was observed among four (CDP-1, -3 to -5) of the five peptides exhibiting different binding characteristics with each CD patient's serum. In contrast, two peptides (CDP-1 and -2) had similar amino acid sequences and similar binding characteristics. Four multiple antigenic peptides (MAP, CDP-1, -3 to -5) were synthesised, and an enzyme linked immunosorbent assay (ELISA) using the four peptides was developed to detect serum antibodies against them. Fifty two of 92 CD patients (56.5%) were detected by ELISA, none of 20 ulcerative colitis (UC) patients, only one of 25 duodenal ulcer patients, and only three of 48 healthy subjects. CONCLUSIONS ELISA using the four peptides isolated in this study may be useful for the differential diagnosis of CD and UC.
