Insights

Post-artesunate delayed hemolysis (PADH) occurred in some children treated for severe malaria in the US. For these pediatric patients, symptom monitoring and counseling may be better than lab tests for managing PADH.

Area of Science:

  • Pediatric infectious diseases
  • Hematology
  • Pharmacology

Background:

  • Severe malaria is a life-threatening condition requiring prompt treatment.
  • Artesunate is a key antimalarial drug.
  • Post-artesunate delayed hemolysis (PADH) is a known complication.

Purpose of the Study:

  • To investigate the incidence and severity of PADH in children treated with artesunate in the United States.
  • To compare the effectiveness of symptom monitoring versus laboratory surveillance for PADH.

Main Methods:

  • Retrospective analysis of 24 children treated with artesunate for severe malaria.
  • Monitoring for signs and symptoms of hemolysis.
  • Review of laboratory data and clinical outcomes.

Main Results:

  • PADH was observed in 6 of 24 pediatric patients.
  • Severe hemolysis requiring hospitalization or transfusion was uncommon.
  • No significant difference in PADH incidence based on monitoring method.

Conclusions:

  • PADH is a potential complication in children treated with artesunate for severe malaria.
  • Symptom monitoring and patient counseling may be a more practical approach than routine laboratory surveillance for PADH in this population.
  • Further research is needed to optimize PADH management strategies.

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...

Antiprotozoal Agents

Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...
