Background: Dengue has a wide spectrum of manifestations, from an asymptomatic condition to dengue shock syndrome. Extensive plasma leakage, severe bleeding, or both, could lead to dengue shock syndrome, a common cause of death in dengue-infected patients. Thrombocytopenia is a common laboratory finding in dengue, which correlates with the disease severity and rapidly resolves during the recovery phase.

Article Synopsis
  • Snakebite-related acute kidney injury (AKI) is prevalent in tropical regions, significantly contributing to morbidity and mortality, with this study aiming to investigate its occurrence, risk factors, and patient outcomes.
  • A prospective study conducted in Myanmar found that 54.3% of snakebite patients developed AKI, often severe, and many required dialysis or died during treatment.
  • Key factors linked to increased AKI risk included bites from Viperidae snakes, high white blood cell counts, low sodium levels, and delayed antivenom administration.

Background: Currently, there are no biomarkers that can predict the incidence of dengue shock and/or organ failure, although the early identification of risk factors is important in determining appropriate management to reduce mortality. Therefore, we sought to determine the factors associated with dengue shock and/or organ failure and to evaluate the prognostic value of serum procalcitonin (PCT) and peripheral venous lactate (PVL) levels as biomarkers of dengue shock and/or organ failure.

Methodology/principal Findings: A prospective observational study was conducted among adults hospitalized for confirmed viral dengue infection at the Hospital for Tropical Diseases in Bangkok, Thailand between October 2013 and July 2015.

Background: Dengue is the most common mosquito-borne viral disease in humans. However, the sensitivities of warning signs (WSs) for identifying severe dengue in adults are low, and the utility of lactate levels for identifying severe dengue in adults has not been verified. Therefore, we aimed to evaluate the diagnostic accuracy of using peripheral venous lactate levels (PVL), as well as WSs established by the World Health Organization, for identifying severe dengue.

In tuberculosis endemic areas, patients with sputum positive for acid-fast bacilli (AFB) are usually diagnosed and treated for pulmonary tuberculosis. The diagnosis of nontuberculous mycobacteria (NTM) lung disease is often ascertained only after lung disease progression occurs, increasing the risk of severe morbidity and mortality. We conducted a matched case-control study among a prospective cohort of 300 patients with newly diagnosed AFB-positive sputum in Thailand during 2010-2012.
