Application of the Sm1-7-qPCR system for identifying S. mansoni DNA in experimentally infected mice.

Schistosomiasis presents a significant public health challenge, especially in regions with inadequate sanitation. Current diagnostic methods, including the Kato-Katz technique, often lack sensitivity in detecting low parasite loads, prompting the search for more precise alternatives. This study introduces the Sm1-7-qPCR system as a highly sensitive and specific diagnostic tool for identifying S.

Evaluation of Chemokines MIG and IP-10 as Immunological Biomarkers of Human Visceral Leishmaniasis: A Systematic Review.

Visceral leishmaniasis (VL) is a neglected tropical disease that is potentially fatal when untreated. Current diagnostic methods have limitations that contribute to ongoing transmission and poor prognosis. Thus, new tests are needed to provide quick, accurate diagnoses and evaluate clinical progression and treatment efficacy.

Evaluation of Proinflammatory Chemokines in HIV Patients with Asymptomatic Infection.

Asymptomatic , when associated with HIV, can become severe and potentially fatal. In this co-infection, the worst prognosis may be influenced by the host's immunological aspects, which are crucial in determining susceptibility. Chemokines play an important role in this process by influencing the cellular composition at affected sites and impacting the disease's outcome.

Evaluation of SmITS1-LAMP performance to diagnosis schistosomiasis in human stool samples from an endemic area in Brazil.

Schistosomiasis is a life-threatening infectious disease categorized by the World Health Organization as a public health issue. New molecular diagnostic alternatives for intestinal schistosomiasis caused by Schistosoma mansoni, such as the loop-mediated isothermal amplification (LAMP), a fast and simple amplification technique, have been proposed for control of this NTD in low-endemicity locations. A LAMP assay was performed to detect the internal transcribed spacer 1 ribosomal gene of S.

Lack of Association of Polymorphisms in and Genes with Fibrosis Severity in Patients with Chronic Hepatitis C.

The IL-22 pathway has been shown to play an important role in the pathogenesis of liver fibrosis. However, little is known about the role of single-nucleotide polymorphisms (SNPs) in IL-22-related genes in relation to the severity of liver fibrosis. This study aimed to investigate the association of polymorphisms in and genes with the severity of liver fibrosis in patients with chronic hepatitis C.

Asymptomatic Leishmania infection in HIV-positive outpatients on antiretroviral therapy in Pernambuco, Brazil.

Background: Visceral leishmaniasis (VL) in HIV-positive individuals is a global health problem. HIV-Leishmania coinfection worsens prognosis and mortality risk, and HIV-Leishmania coinfected individuals are more susceptible to VL relapses. Early initiation of antiretroviral therapy can protect against Leishmania infection in individuals living in VL-endemic areas, and regular use of antiretrovirals might prevent VL relapses in these individuals.

Identification of nontuberculous mycobacteria species by multiplex real-time PCR with high-resolution melting.

Introduction: Nontuberculous mycobacteria (NTM) species, as human pathogens, are increasing in the world, as is the difficulty of accurately identifying them. Differential diagnosis, especially between the M. tuberculosis complex and NTM species, and the characterization of NTM species is important.

Influence of LGALS3 and PNPLA3 genes in non-alcoholic steatohepatitis (NASH) in patients undergone bariatric surgery.

Aim: This study evaluated the genesPNPLA3 and LGALS3 in patients who have undergone bariatric surgery.

Methods: Individuals with NAFLD and NASH were evaluated, the DNA was extracted from total blood for genotyping of rs4644, rs4652 from LGALS3 and rs738409 from PNPLA3 genes, the total RNA was obtained from liver biopsy. For the detection of the molecular targets, real-time PCR through Taqman probes was used.

Loop-mediated isothermal amplification methods for diagnosis of visceral leishmaniasis () - a systematic review.

: Visceral leishmaniasis (VL) is a life-threatening infection remaining as one of the most neglected tropical diseases around the world. Despite scientific advances, an accurate diagnosis of VL remains a challenge. Loop-mediated isothermal amplification (LAMP) has emerged as a promising diagnostic tool with the possibility of becoming a point-of-care test to guide VL diagnosis and treatment.

Higher levels of TNF and IL-4 cytokines and low miR-182 expression in visceral leishmaniasis-HIV co-infected patients.

Aims: The aim of the present study was to assess serum cytokine and miRNA expression in visceral leishmaniasis-HIV (VL-HIV) co-infection and HIV mono-infection.

Methods And Results: We analysed 113 serum samples from HIV patients in areas endemic for leishmaniasis. The diagnosis of VL was confirmed in 65 of these 113 samples.

SLC11A1 (rs3731865) polymorphism and susceptibility to visceral leishmaniasis in HIV-coinfected patients from Northeastern Brazil.

Following the emergence of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), the number of visceral leishmaniasis-HIV (VL-HIV) coinfections has increased worldwide, mainly in Brazil. The development of clinical forms of VL can be influenced by nutritional status, age, and host genetic factors, which are important variables determining susceptibility to disease. There are no studies with a candidate gene approach assayed directly in the VL-HIV-coinfected population.

Rapid Tests and the Diagnosis of Visceral Leishmaniasis and Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome Coinfection.

After the emergence of the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), the number of visceral leishmaniasis (VL)-HIV/AIDS coinfections has increased worldwide. Herein, we assessed the usefulness of an rK39-based immunochromatographic test (rK39 ICT) (DiaMed-IT LEISH(®); DiaMed AG, Cressier-sur-Morat, Switzerland) and a latex agglutination test (KAtex; Kalon Biological, Guildford, United Kingdom) for urinary antigen detection to diagnose VL in 15 HIV/AIDS patients from northeastern Brazil. VL diagnosis was based on clinical findings, cytology, serology, parasite DNA, and/or urinary antigen detection.
