What is new in Malaria Management ? Dr. PC Bhattacharyya Sr. Consultant Physician down town hospital Guwahati ,Assam
Current Scenario • No significant development in management since the advent of artemisinin. • Many new drugs are in experimental stage • Various combination of different drugs are tried with variable success • Newer investigations contributed much towards the successful management
Newer Investigations Serological Tests : Molecular biological techniques DNA Probes RNA probes Transcript amplification system and target amplification by PCR Probe amplification ring Q beta replicase Compound or ‘Christmas tree’ Probes Fluorescence microscopy
Management (i) Immediate general management Immediate admission in ICU Resuscitation Airway/Circulation by ALS technique ABG/Serum electrolyte estimation Coagulation profile Detection of pulmonary oedema and ARDS & ventilatory support
Management (ii) 8. Hypoglycaemia 9. Circulatory collapse 10.Renal shutdown- Dialysis 11. Anaemia – blood transfusion 12. Haemoglobinuria 13. Hyperpyrexia 14. Jaundice & exchange transfusion
Newer Drugs - I • TETRACYCLENE : Doxycycline, Cotrimoxazol Clindamycin • NAPHTHOQUINONE : (Atovaquone or BW 566 C80), • VINYL SULPHONES : Inhibit cystesine proteinase ) . • WR 238 ,605 : New 8 aminoquinolone, • SULPHONES/ BIGUANIDES
NEWER DRUGS - II AZITHROMYCIN DESFERRIXAMINE DRUGS WHICH REVERSE CHLOROQUINE RESISTANCE Calcium channel blocker. MISCELLANEOUS Pyronaridine, Benflumentol, Hydroxy Piperaquine, Trioxane. Teraoxanes, Hydroxynaphthoquinones & Pyridianomenthanols. Dapsone, Ketoconazole, Miconazole, Ampho-B
Exchange Transfusion Rationale • Rapid reduction of parasite load • Improving rheology • Reduction of microcirculatory sludge • Correction of anaemia • Buying time for optimum action of drugs
Exchange Transfusion Indications • Parasitaemia >30% without organ dysfunction • Parasitaemia > 10% with organ dysfunction • Pregnancy • Patient >60 yrs. of age
Exchange transfusion Technique • Through Femoral/brachial vein • Patients blood exchanged in small quantity • Volume exchanged- 2000ml- parasitaemia >10% 3000ml – parasitaemia >11-20% 4000ml – parasitaemia >20%
Exchange transfusion Our experience in DTH Number of cases 9 • Exchange transfusion 3 cases 2 had ARDS, All survived • Without exchange transfusion 6 cases 5 cases died (4 cases had ARDS)
