MALARIACaused by blood protozoa : Plasmodium Plasmodium sp. Infecting human : • P. falciparum falciparum malaria; tropical malaria; malignant tertian malaria • P. vivax vivax malaria; benign tertian malaria • P. ovale ovale malaria; tertian malaria • P. malariae quartan malaria • P. knowlesi monkey malaria human
MALARIA LIFE CYCLE Clinical manifestation
Acute attack of malaria • Cold stage • Chill(dingin), rigor(kaku) • Hot Stage • Fever increased(demam tinggi) • Headache(sakit kepala) • Flashing face(muka merah) • Sweating stage • Profuse sweating(banyak keringat) • Decrease body temperature(demam turun) • Feeling of Relief (fall a sleep) (merasa sehat)

Schizont stages P.f. P.m. P.v. P.o.
Malaria • P.falciparum causing severe malaria • Clinical manifestation: due to eritrocytic stage • Rupture of IRBC : released Antigens & toxins • Mature trophozoite adhere to endothelial cells • Haemolytic anaemia: • Periodical rupture of mature schizonts • Immune complex INDIRECT rupture of uninfected normal erythrocytes • Marrow suppression by some toxin of malaria parasites Marrow aspirates: dyserythropoiesis, phagocytosis of uninfected red cells

Malaria & Pregnancy Pregnancy Physiological anemia during pregnancy Microcirculatory arrest in the placenta may cause fetal death, small-for-date babies, and premature stage (mainly in 1st pregnancy) Congenital malaria May occur in all species of malaria but very rare Progressive hemolytic anemia may accur
ANTIMALARIALS • TISSUE schizontocides: primaquine (8-aminoquinoline derivatives) • ERYTHROCYTIC schizontocides: • Chloroquine • Sulfadoxine-pyrimethamine • Quinine • Antibiotics • GAMETOCYTOCIDES: primaquinelength species dependent • NEW POLICY (2008) ACT • Artemisinine Combination Theraphy
Preparation of thin and thick blood smears
Preparation of thin and thick blood smears
Giemsa staining • Thin film were fixed in absolute methanol for 30-60 second • No fixation for thick smear • Prepare 5% Giemsa solution with buffer/destilated water • Thick and thin smear were put into 5% Giemsa for 30 minutes • Carefully washed off the stain in runing tap water • Dry the slides and examined with 100x objective

Immuno-chromatographic technology Rapid Diagnostic Test (RDT) RDT for Malaria: detect malaria antigens
Diagnosis Parasitic Infection using Polymerase Chain Reaction (PCR) Every single parasite DNA were amplified thousands time using specific Primers easily detected
Pengobatan malaria falsiparum dengan Dihydroartemisinin+Piperaquin(DHP) dan Primakuin Dihydroartemisinin = 2-4 mg;Kg BB Piperakuin = 16-32 mg/Kg BB Primakuin = 0,75 mg/Kg BB (untuk membunuh gametocyte)
Pengobatan malaria vivak dengan DHP+Primakuin Dosis Primakuin = 0,25 mg/Kg BB selama 14 hari (membunuh gametosit dan hypnozoit dalam sel hati)
Pengobatan Malaria falsiparum dg Artesunat-Amodiakuin Artesunat = 4 mg/Kg BB Amodiakuin = 10 mgkKg BB Primaquin 0,75 mg/Kg BB
Pengobatan Malaria vivak dg Artesunat-Amodiakuin dan Primakuin Artesunat = 4 mg/Kg BB Amodiakuin = 10 mgkKg BB Primaquin 0,25 mg/Kg BB selama 14 hari
