Article Synopsis
  • Soluble CD163 (sCD163) is a key inflammatory mediator linked to both acute and chronic inflammation, and its levels in the body reflect the presence of CD163-expressing macrophages.
  • The shedding of the CD163 receptor leads to increased sCD163 concentrations, which plays various roles including scavenging hemoglobin, serving as a macrophage marker, and affecting immune responses.
  • Elevated sCD163 levels are associated with the severity and progression of various diseases like asthma, sepsis, diabetes, and rheumatoid arthritis, highlighting its importance in disease diagnosis and management.

  • Rising antimicrobial resistance (AMR) in Salmonella Typhi poses a significant threat to typhoid treatment, especially in high-burden countries like Bangladesh, where long-term data is lacking.
  • The study analyzed typhoid cases in Dhaka from 1999 to 2022, finding a decrease in multidrug resistance (MDR) from 38% to 17% and a drop in cotrimoxazole consumption, while resistance to ciprofloxacin remained high (>90%).
  • With a noted decline in MDR, the research suggests that first-line antibiotics may be safely reintroduced for treating typhoid fever, pending further decreases in resistance rates.
