Characteristic profile of antibody responses to PPD, ESAT-6, and CFP-10 of Mycobacterium tuberculosis in pulmonary tuberculosis suspected cases in Surabaya, Indonesia.

Accurate and rapid diagnostic tools are important aspects of managing tuberculosis (TB) cases appropriately. However, the sensitivity and specificity of diagnostic kits based on immune response such as the tuberculin skin test (TST) and interferon gamma release assay (IGRA) are still debated. Thus, the exploration and assessment of specific biomarker-targeted antibodies are needed for the development of an accurate and rapid diagnostic tool. The present study was conducted in patients with a respiratory problem suspected to be TB at Dr. Soetomo Hospital, Surabaya, Indonesia. Among 102 patients tested by GeneXpert and AFB, 59 serum samples were from cases retrospectively determined to have active TB. A total of 102 serum of healthy controls (HC) was also collected. The PPD antigen and the recombinant CFP-10 and ESAT-6 proteins were prepared. Antibody responses against these proteins were evaluated by ELISA. All samples were also screened for the possibility of Mycobacterium avium-intracellulare complex (MAC) infection using Capilla MaC kit. The results showed that TB patients had a significantly higher concentration of IgG antibody in response to PPD than the HC. In addition, the receiver operating characteristic (ROC) curve analysis showed that PPD was acceptable for diagnostic purposes with an AUC value of 0.835 (95% CI 0.770-0.900, p < 0.0001). However, ESAT-6 and CFP-10 had low AUCs, and 32 samples from both groups showed a low concentration of IgA antibody against all antigens. The MAC detection results also showed that the concentration of IgA in the HC group was the highest. The current results indicate that PPD is a better antigen for antibody-based detection of TB than ESAT-6 and CFP-10. Based on the MAC detection assay, 53 people in the HC group were probably infected with rapidly growing nontuberculous mycobacteria (NTM), although antibody response to PPD was low.

Comparison of two kits of anti-infliximab antibodies plasmatic measurement.

Infliximab (IFX) is a chimeric monoclonal antibody which has proven its efficacy in the treatment of inflammatory diseases. However, its efficacy can be limited by the development of anti-IFX antibodies (ATI) resulting in a therapeutic failure of IFX. ATI plasmatic monitoring is then indicated to optimize IFX treatment. The aim of this study was to validate an ELISA (enzyme linked immuno sorbent assay) method of ATI plasmatic monitoring.

Evaluation of novel rapid detection kits for dengue virus NS1 antigen in Dhaka, Bangladesh, in 2017.

Dengue virus (DENV) infection is one of the biggest challenges for human health in the world. In addition, a secondary DENV infection sometimes causes dengue hemorrhagic fever (DHF), which frequently leads to death. For this reason, accurate diagnosis record management is useful for prediction of DHF. Therefore, the demand for DENV rapid diagnosis tests (RDTs) is increasing because these tests are easy and rapid to use. However, commercially available RDTs often show low sensitivity for DENV and cross-reactivity against other flaviviruses, especially Zika virus (ZIKV).

Possible role interleukin-21 and interleukin-33 in patients with genital warts.

Genital warts (GWs) are most prevalent sexually transmitted infections; presenting especially among the sexually active young population of both sexes. Efficient cell-mediated immunity is needed for regression of GWs. To clarify the reactivity of cellular immunity among patients with GWs by means of measurements of their levels of serum interleukin (IL)-21 and IL-33, hence, to identify the possible role of IL-21 and IL-33 in GWs. This study aimed to evaluate serum levels of IL-21 and IL-33 among patients with GWs in comparison with the results of the controls. Levels of serum IL-21 and IL-33 were assayed utilizing commercially enzyme-linked immune-sorbent assay (ELISA) kits in 45 patients with GWs and 45 healthy control subjects. Levels of serum IL-21 and IL-33 were significantly decreased among patients with GWs in comparison with the controls (P-value <0.0001). There was a highly significant positive correlation between IL-21 and IL-33 (r₌ 0.73, P-value <0.0001). Low levels of serum IL-21 and IL-33 could have a contributive role in development, persistence, severity, and recurrence of GWs which rely basically on the defectiveness of cell-mediated immunity. This could receive new light on non-conventional strategies for the prospective medical therapies of GWs by means of regulation of IL-21 and IL-33. This article is protected by copyright.

[A Case of Congenital Syphilis and Prozone Phenomenon].

The screening for syphilis during pregnancy is important to prevent intrauterine transmission and complications. Prozone phenomenon may cause a false negative result in non-treponemal syphilis tests, which complicates an accurate diagnosis. In this case report a newborn syphilis case was presented to emphasize the importance of reverse algorithm in diagnosis and the prozone phenomenon which can cause problems in rapid plasma reagin (RPR) test. The 2920 g infant patient was born from a 24-year-old mother with no known diseases, at the 35th week of gestation by cesarean section due to premature rupture of membranes. The initial physical examination of the newborn revealed erythema and exfoliation of the bilateral hands and feet. Laboratory results revealed CRP: 90 mg/L, WBC: 19.2 x 103/µl, hemoglobin: 9.5 g/dl, platelet count: 214 x 103/µl, HIV-Ag/Ab: non-reactive, anti-Toxoplasma gondii IgM and IgG: negative, anti-cytomegalovirus IgM: negative, anti-cytomegalovirus IgG: positive (128.7 AU/ml), anti-Rubella IgM: negative, anti-Rubella IgG: positive (26 IU/ml), anti-Treponema pallidum (anti-T.pallidum) antibody [IgM and IgG by the chemiluminescence microparticle enzyme immunoassay (Architect Syphilis TP; Abbott Japan Co, Japan)]: positive (Signal Cut Off value (S/CO): 28.35), and RPR (Omega Diagnostics, UK): negative. All of the above ELISA tests were performed by using Architect (Abbott Diagnostics, Wiesbaden, Germany) kits. When the RPR test was repeated with serial dilutions of the serum in order to detect prozone phenomenon, positive reaction was detected starting from 1:2 and ending at 1:64 dilution. It was determined that the mother was not tested for syphilis during her pregnancy. When both the mother and the father were tested for syphilis, the mother's anti-T.pallidum total antibody test result was reactive (S/CO: 30.52) and the RPR was positive at 1:32 dilution, while the father's anti-T.pallidum total antibody test result was reactive (S/CO: 16.05) and the RPR was negative. A four-fold difference between the maternal and infant RPR dilutions is required by the guidelines for a laboratory diagnosis of congenital syphilis. Although this criterion was not met in the newborn, the case was accepted as congenital syphilis due to clinical findings. Congenital syphilis must be considered in the differential diagnosis in the presence of skin manifestations at the birth and early neonatal period. Accurate and early diagnosis of the disease is important to start appropriate treatment and prevent complications. As described in the presented case, the use of reverse syphilis test algorithm will enable to reach the correct diagnosis of the infection. If the result of the treponemal test is positive and the RPR test is negative, prozone phenomenon should be considered and the RPR test should be repeated with serial serum dilutions.

HEV seroprevalence in blood donors in Turkey by two commercial total anti-HEV Ab ELISA kits.

Previous hepatitis E virus (HEV) seroprevalence studies in Turkey have shown high variabilities, leading to conflicting results. We aimed to re-evaluate HEV seroprevalence among blood donors in Turkey using the Wantai (Beijing, China) and the Dia.Pro (Milan, Italy) total anti-HEV antibody (Ab) enzyme-linked immunosorbent assay (ELISA) kits and compare their performances and to investigate the presence of HEV RNA in blood donors. Serum total anti-HEV antibodies were determined in a total of 2011 volunteer blood donor samples collected from different regions of Turkey (807 from Ankara, 243 from Kayseri, 284 from İzmir, 200 from Malatya, 200 from Kahramanmaraş, and 277 from Van). HEV RNA was evaluated by a real-time polymerase chain reaction in a total of 272 anti-HEV seropositive samples. The country-wide HEV seroprevalence was calculated as 11.5% (Dia.Pro) and 12.2% (Wantai) with seropositivity rates of 12.0%-12.5% in Ankara, 7.4%-8.2% in Kayseri, 14.5%-15.5% in Malatya, 8.1%-8.8% in İzmir, 15.0%-16.0% in Kahramanmaraş, and 12.6%-13.4% in Van by Dia.Pro and Wantai kits, respectively. The lowest detectable Ab concentrations were 0.16 and 0.14 units/mL WHO, for the Dia.Pro and the Wantai assays, respectively, showing no significant difference between assays. HEV RNA was not detected in any of the anti-HEV seropositive samples. Compared with previous studies, HEV was shown to have a higher overall seroprevalence in Turkey. Despite its limitation, the current study represents the most comprehensive HEV seroprevalence study in Turkey performed with two different commercial ELISA assays with high sensitivities so far. Further investigation is required to determine HEV genotypes in Turkey.
