Severe falciparum malaria is a medical emergency that is associated with a high rate of mortality, even when treated in an Intensive Care Unit. Until recently, intravenous quinine was the standard treatment; however, artemisin derivatives are now regarded as the first-line treatment for multidrug-resistant falciparum malaria. Although several studies have demonstrated the superiority of Artesunate, this drug is not licensed in many countries. This article describes the case of an HIV-positive patient, who returned from Africa and presented with 10% parasitemia and clinical signs of severe falciparum malaria; this individual was successfully treated with a combination of artesunate and quinine. Artesunate was imported from the foreign market, and written consent for its administration was obtained in advance. Parasite clearance was rapidly achieved; however, on day IV, the patient developed acute respiratory distress syndrome that required mechanical ventilation. The patient was extubated on day XIV and discharged on day XXV. Due to its rapid action, artesunate was likely responsible for the good clinical outcome in this case; however, in order to clarify the role of this new combination therapy, further studies are required.

Drug resistance resulting from mutations in Plasmodium falciparum, that caused the failure of previously effective malaria drugs, has continued to threaten the global malaria elimination goal. This study describes the profiles of P. falciparum chloroquine resistance transporter (Pfcrt) and P.

The article presents the diagnosis and treatment of an imported case with severe malaria, and the effect of plasma exchange combined with continuous renal replacement therapy. Severe malaria is characterized by complex clinical symptoms and multiple complications, and plasma exchange combined with continuous renal replacement therapy has a satisfactory therapeutic efficacy for severe malaria.

Background: The Plasmodium proteasome emerges as a promising target for anti-malarial drug development due to its potential activity against multiple life cycle stages.
Methods: In this investigation, a comparative analysis was conducted on the structural features of the β5 subunit in the 20S proteasomes of both Plasmodium and humans.
Results: The findings underscore the structural diversity inherent in both proteasomes.

Malaria rapid diagnostic tests (mRDTs) that detect histidine-rich protein 2 (HRP2) remain the mainstay of falciparum malaria diagnosis in Sub-Saharan Africa. Understanding their test characteristics when used for surveillance in asymptomatic populations is important. We explored the rate of false-positive and false-negative mRDT results among asymptomatic persons >5 years old screened for malaria at schools and clinics in the rural Bagamoyo District using 18S ribosomal RNA real-time polymerase chain reaction (qPCR) as the reference test.

Introduction: A continuing challenge for malaria control is the ability of to develop resistance to antimalarial drugs. Members within the transcription factor family AP2 regulate the growth and development of the parasite, and are also thought to be involved in unclear aspects of drug resistance. Here we screened for single nucleotide polymorphisms (SNPs) within the AP2 family and identified 6 non-synonymous mutations within AP2-06B (PF3D7_0613800), with allele frequencies greater than 0.
