In the earlier blog posts, we gave an outline on preventive medications and treatment options for malaria. In this post, I will provide more details on artemisinin-based combination therapies which are recommended for the treatment of uncomplicated malaria caused by P. falciparum.
For recap purposes, P. falciparum malaria parasitic infections are potentially severe and fatal; and rapid diagnosis and appropriate treatment must be administered as soon as possible to improve the prognosis.
Clinical manifestations of severe P. falciparum malaria
The clinical manifestations of severe P. falciparum malaria infections are as follows:
Ps: I have provided translations for people unfamiliar with medical terminologies
- Cerebral malaria – complications in the brain
- Severe anemia – severe lack of healthy red blood cells
- Respiratory distress – difficulty in breathing
- Renal failure – kidney failure
- Hypoglycaemia – drastic low blood sugar level
- Circulatory collapse – shock
- Coagulation failure – unable / decreased ability to stop bleeding
Artemisinin-based combination therapies
Artemisinin-based combination therapies (ACTs) are the recommended treatment option for uncomplicated/ non-severe form of P. falciparum malaria. ACTs refer to the combination of two malaria drugs with different mechanisms of action which bolsters efficacy and they are thought to have the potential to reduce spreading and resistance development.
Problems facing artemisinin-based combination therapies
- P. falciparum malaria resistance has developed in some countries.
- Artemisinin-based combination therapies are expensive and inaccessible to needy patients in developing countries.
- Artemisinin-based combination therapies are only administered after patients with severe malaria can tolerate oral therapy.
Alternative novel treatment options
How about considering novel malaria treatment alternatives utilising nanotechnology and gene therapy?
In the above figure, the blue particles which are extremely small–in nanometers–mimic the red blood cells by tricking malaria parasite particles to bind onto the nanoparticles. This effectively prevents the parasitic malaria from invading and causing death of red blood cells.
And, here I have something for you to ponder on whether we can ethically use gene therapy to treat mosquito-borne diseases such as malaria. Enjoy this highly animated and interesting video below.
