AI Article Synopsis

  • A study involved 26 Yemeni patients with visceral leishmaniasis (VL), assessing the efficacy of a C-ELISA test compared to traditional microscopy for diagnosing the disease.
  • The C-ELISA test showed higher sensitivity, identifying additional positive cases missed by microscopy, with 82.3% of patients testing positive on both methods.
  • Among the treated patients, 76.3% responded to sodium antimony gluconate, with the C-ELISA effectively monitoring treatment success by showing a decrease in antibody inhibition in drug-responsive patients.

Article Abstract

Twenty six Yemeni patients with clinically visceral leishmaniasis (VL) and laboratory abnormalities were subjected to L. donovani species-specific monoclonal antibody (D2) and a competitive enzyme-linked immunosorbent assay (C-ELISA). The results were compared with those obtained by microscopy Giemsa stained tissue smears of bone marrow or splenic aspiration. Of the patients, 51 (82.3%) were positive and 3 (4.8%) were negative by both microscopy and C-ELISA. An additional 8 (12.9%) who were negative by microscopy were positive by C-ELISA. 59 patients were treated with sodium antimony gluconate, 45 (76.3%) were drug responsive and 14 (23.7%) were drug resistant. The C-ELISA of 17 patients before and after chemotherapy showed a significant decrease in percent inhibition of monoclonal antibodies D2 in drug responsive patients. In drug-unresponsive patients the percent inhibition of D2 was unchanged or slightly increased. The results indicate that C- ELISA is more sensitive and specific than microscopy, especially for early diagnosis of VL and to evaluate the success of drug treatment.

Solid-phase immunosorbent reactions, such as ELISA, are widely used for detecting, identifying, and quantifying protein markers. However, traditional centimeter scale well-based immunoreactors suffer from low surface-to-volume (S/V) ratios, leading to large sample consumption and a long assay time. Microfluidic technologies, particularly tubular microfluidic immunoreactors, have emerged as promising alternatives due to their high S/V ratios.

Several interventional strategies have been implemented in malaria endemic areas where the burden is high, that include among others, intermittent preventive treatment (IPT), a tactic that blocks transmission and can reduce disease morbidity. However, the implementation IPT strategies raises a genuine concern, intervening the development of naturally acquired immunity to malaria which requires continuous contact with parasite antigens. This study investigated whether dihydroartemisinin-piperaquine (DP) or artesunate-amodiaquine (ASAQ) IPT in schoolchildren (IPTsc) impairs IgG reactivity to six malaria antigens.

Traumatic brain injury (TBI)-associated neuroinflammation and neurotoxicity can induce gastrointestinal dysfunction through the brain-gut axis. Partially hydrolyzed guar gum (PHGG) was demonstrated to exert beneficial health effects by altering gut microbiota and short-chain fatty acids (SCFAs) production. Our study aimed to explore the effects of PHGG on gastrointestinal dysfunction in TBI mouse models.

Functional characterization of novel anti-DEFA5 monoclonal antibody clones 1A8 and 4F5 in inflammatory bowel disease colitis tissues.

Background: The aberrant expression of α defensin 5 (DEFA5) protein in colonic inflammatory bowel diseases (IBDs) underlies the distinct pathogenesis of Crohn's colitis (CC). It can serve as a biomarker for differentiating CC from Ulcerative colitis (UC), particularly in Indeterminate colitis (IC) cases into UC and CC. We evaluated the specificity of commercially available anti-DEFA5 antibodies, emphasizing the need to further validate their appropriateness for a given application and highlighting the necessity for novel antibodies.

Enzyme-linked immunosorbent spot analysis is frequently used to investigate immune responsiveness during clinical trials. However, ELISpot classically utilizes peripheral blood mononuclear cell isolates from whole blood, requiring relatively high blood draw volumes and removing both granulocytes and bound drug. Here, we describe a novel protocol whereby CD45 cells are magnetically isolated from human whole blood and co-incubated with serum isolated from the same subject.
