Line Immunoassay for Confirmation and Discrimination of Human T-Cell Lymphotropic Virus Infections in Inconclusive Western Blot Serum Samples from Brazil Immunoassays

Difficulties in confirming and discriminating human T-cell lymphotropic virus type 1 (HTLV-1) and HTLV-2 infections by serological Western blot (WB) assays (HTLV Blot 2.4; MP Biomedicals) have been reported in Brazil, mainly in HIV/AIDS patients, with a large number of WB-indeterminate and WB-positive but HTLV-untypeable results. Nonetheless, a line immunoassay (LIA) (INNO-LIA HTLV-I/II; Fujirebio) provided enhanced specificity and sensitivity for confirming HTLV-1/2 infections. To add information concerning the improved ability of the LIA in relation to WB when applied to samples of individuals from different risk groups from Brazil, we performed the present study. Three groups were analyzed: group 1 (G1), with 62 samples from HIV/AIDS patients from São Paulo, SP (48 WB indeterminate and 14 HTLV untypeable); group 2 (G2), with 24 samples from patients with hepatitis B or hepatitis C from São Paulo (21 WB indeterminate and 3 HTLV untypeable; 17 HIV seropositive); and group 3 (G3), with 25 samples from an HTLV outpatient clinic in Salvador, Bahia (16 WB indeterminate and 9 HTLV untypeable; all HIV seronegative). Overall, the LIA confirmed HTLV-1/2 infection (HTLV-1, HTLV-2, or HTLV) in 66.1% (G1), 83.3% (G2), and 76.0% (G3) of samples. Interestingly, the majority of WB-indeterminate results were confirmed by the LIA as being HTLV-2 positive in G1 and G2 but not in G3, in which the samples were defined as being HTLV-1 or HTLV positive. These results agree with the...

We described the frequency of disease overlaps; for example, 34.7% of clients with a syphilis record had a gonorrhea record. We quantified known overlaps, finding 1274 clients had gonorrhea, infectious syphilis, and HIV/AIDS records, and potentially emerging overlaps, finding 59 clients had HIV/AIDS, hepatitis C, and iGAS records. IMPLICATIONS: Our novel person-based integrated surveillance dataset represents a platform for ongoing in-depth assessment of disease overlaps such as the relative timing of disease records. It enables a more client-focused approach, is a step towards improved characterization of syndemics i...

This study assessed which HIV care quality indicators were associated with healthcare resource utilization and costs. Design: Retrospective analysis of Texas Medicaid claims data (01 January 2012 to 31 September 2016). Methods: Included patients had at least two HIV-related medical claims during the identification period (01 July 2012 to 31 August 2014) (index = date of first HIV claim), were 18–62 years at index, and were continuously enrolled in the 6-month pre-index and 1-year post-index periods. Dependent variables included emergency department (ED) visits, inpatient hospitalizations, prescription count...

Conclusion: Prevalence of transfusion-transmissible viral infections was higher among hemodialysis patients, especially HCV infection which was an alarming situation and therefore strict adherence to infection control strategies, barrier precautions, and preventive measures, including routine hepatitis B vaccination and regular virological follow-up were recommended along with regular education and training programs of technical and nursing personnel's involved with dialysis patients.

Authors: Tang Q, Zhang X, Lu H Abstract Acquired immune deficiency syndrome (AIDS), hepatitis B virus (HBV), hepatitis C virus (HCV), gonorrhea and syphilis are the major sexually transmitted diseases (STDs) in the world, which are the focus of epidemic prevention and control in China. The epidemiological trend analysis of STDs in Shanghai could reflect the epidemic situation of these diseases in high-income areas of China, providing a reference for how to control their epidemic. Although the overall incidence rate of infectious diseases levelled off after 2009, Shanghai still faces many new obstacles in the fight ...

This study investigated factors associated with liver enzymes abnormalities among human immunodeficiency virus (HIV) infected individuals on ART from the Lake Victoria zone, Tanzania. Methods: A cross-sectional study involving a total of 230 sera from HIV seropositive patients from different regions of the Lake Victoria zone was carried out in July 2017. All samples with required variables/parameters such as age, sex, ART regimen, and residence were serially included in the study. Hepatitis B virus (HBV) and Hepatitis C virus (HCV) detection and liver enzymes assays (alanine transaminase (ALAT) and aspartate transamina...

Purpose: Viral hepatitis can cause significant morbidity and mortality in patients receiving chemotherapy. London cancer guidelines recommend universal pretreatment screening for hepatitis B (HBV) and hepatitis C (HCV). HIV-infected patients are at higher risk of developing AIDS-defining and non-AIDS-defining cancers. HIV testing for all oncology patients has been recommended. Studies reveal up to 30% of breast cancer patients may have undiagnosed diabetes [1]. Oncology patients with diabetes have an increased risk of complications: chemotherapy toxicities, steroid-induced hyperglycaemia and sepsis.
