Melioidosis after a long silence in Sri Lanka: an environmental hazard and dilemma in diagnosis, with recovery and longitudinal follow-up for 13?years: a case report.

ABSTRACT: BACKGROUND:Melioidosis is a potentially fatal bacterial infection caused by Burkholderia pseudomallei. The existence of melioidosis in Sri Lanka was once unheard of, and entertaining it as a diagnosis in clinical practice was extremely rare. CASE PRESENTATION:In this case report, we describe the clinical, epidemiological, and longitudinal follow-up data of a 58-year-old previously healthy Sinhalese woman who presented to our hospital with protracted febrile illness of 5?weeks' duration, later developing multiple abscesses at different sites of the body. There was a significant delay in confirming the diagnosis of melioidosis by isolating B. pseudomallei from blood and pus cultures. The patient recovered fully with a prolonged course of antibiotics and has remained in good health over the last 13?years without recurrence. Despite being immunocompetent, she had contracted the infection by a brief contact with mud soil in a footpath. CONCLUSIONS:A high index of clinical suspicion along with laboratory support is needed to confirm the diagnosis of melioidosis. Treatment with sensitive antibiotics over a long duration is needed, and longitudinal follow-up is essential to detect recurrences. This case raised awareness and created renewed interest in studies of melioidosis in Sri Lanka.

Project description:Introduction. Melioidosis, caused by Burkholderia pseudomallei, in endemic areas, poses a challenge for treating the diseased populations without accurate diagnosis, and the disease-specific biomarkers linked with the infection have yet to be reported. Due to the invasive nature of the causative agent, Burkholderia pseudomallei, host innate effector mechanisms, including autophagy are known to be activated, resulting in differential expression of cellular proteins and immune markers. Identification of a disease-specific biomarker associated with B. pseudomallei infection will be helpful to facilitate rapid confirmation of melioidosis, which would enable early treatment and therapeutic success.Aim. We aimed to assess the levels of a host autophagy component, p62/NBR1, which function as a cargo-receptor in the process of autophagy activation leading to the degradation of ubiquitin-coated intracellular bacteria in which p62/NBR1 itself is degraded in the clearance of the pathogen. We further probed the extent of intracellular p62/NBR1 degradation and assessed its potential as a melioidosis biomarker.Methodology. We analysed peripheral blood mononuclear cell (PBMC) lysates using an ELISA-based assay for detecting cytosolic autophagy-related proteins p62/NBR1. We measured p62/NBR1 levels in diseased (confirmed B. pseudomallei infection) and non -diseased populations and utilized receiver operating characteristic (ROC) curve and max Youden index analysis for evaluating potential disease biomarker characteristics.Results. Our results revealed a three to fivefold increase in p62/NBR1 levels confirmed melioidosis cases compared to uninfected healthy donors. Comparable to p62/NBR1, levels of cytosolic LC3-I levels also increased, whereas the levels of degraded membrane bound form LC3-II was low, suggesting autophagy deficiency. Proinflammatory serum cytokine response, particularly IL-6, was consistently higher alongside B. pseudomallei infection in comparison to healthy controls.Conclusions. ROC curve and max Youden index analysis suggest that increased p62/NBR1 levels in diseased populations display characteristics of a potential disease biomarker in melioidosis and illustrates that an elevated p62/NBR1 level, in conjunction with B. pseudomallei infection associated with autophagy deficiency.
