Current National Drug Policies in Lao P.D.R. By Dr Samlane Phompida Centre of Malariology, Parasitology & Entomology
Antimalarial drug resistance • Chloroquine: CQ • 1999: 46% treatment failure (33% RII/RIII) in VP • 2001-2002: 30-55% treatment failure in SVK, ATP, LN • Sulfadoxine-pyrimethamine: SP • 2001: 18-35% treatment failure in SVK, ATP • 2002: 11% treatment failure in CPS (4% ETF, 7% LPTF) • CQ+SP: • 2001: 16-22% treatment failure in ATP • 2002: 8% treatment failure in SVK • Mefloquine: MQ • 2001: 100% ACPR in ATP (14 days follow up) • Artesunate+mefloquine: • 2002-2003: 100% ACPR in SVK and LN (42 days follow up) • Artemether+lumefantrine: • 2002: 97% ACPR in SVK (42 days follow up) • 2003: 93% ACPR in LN (42 days follow up) • Artekin(Dihydroartemisinin+piperaquine) • 2004: 93% ACPR in SVK (42 days follow up)

Past anti-malarial drug policy in Lao PDR • Laos has adopted one treatment policy of malaria for different levels of health facilities system • Chloroquine or sulfadoxine/pyrimethamine for the treatment of uncomplicated malaria • Quinine i.v. for complicated malaria and in case of treatment failure with CQ or SP. • 1st line treatment (CQ) was available at village level
Enable VHWs in the correct treatment of uncomplicated malaria based upon clinical signs. • Enable central-, regional-, provincial-,district hospitals to diagnose and treat complicated malaria correctly • Regular monitoring of resistance to anti-malarial drug/ combinations at sentinel sites • National policy includedchemoprophylaxis for pregnant women and vulnerable groups, but implementation limited
Antimalarial drug resistance situation • 2001-2002: • 40-78% of failure to CQ (14/28/42 days) • 18-36% of failure to SP (42 days) • 8% of failure to CQ+SP (42 days) • 92% of efficacy of Coartem® (42 days) • 100% of efficacy of A+M (42 days) • 2003: • 94% efficacy of Coartem® (42 days) • 100% efficacy of A+M (42 days)
Response to drug resistance • Round table to discuss on the treatment policy (2003) • Introduction of CQ plus SP as interim policy • Change of policy to combination therapy: Coartem with the use of RDTs, esp at district and village level, free of charge to the patient • Registration of Coartem blisters only use by NMCP • Definition of 4 categories of weight and age • Launch of procurement of ACT through WHO in December 2003 • Production of guidelines on the use of RDT and ACT • Production of IEC materials on the use of ACT • TOT (incl on RDTs) in 3 pilot provinces (SRV, SK, ATP) in 2004, expanded to all provinces in 2005
Different options and alternatives • Artesunate+mefloquine • First choice • Procurement issues: no product available meeting international GMP standards • Alternative ACTs • Coartem® was adopted as 1st line treatment by Taskforce. Inform GFATM on change in policy, register Coartem, define weight and age dosages, produce new guidelines, new IEC materials, re-organize TOT on Coartem • Artekin® : not currently WHO-recommended
New Malaria Treatment Policy, Lao PDR: • 1st line: Artemether + Lumefantrine (CoArtem) – all levels of health services • 2nd line: Quinine + doxycycline • Severe and complicated malaria: inj. Artesunate or quinine • Small children: artesunate supp. • Pregnant women: quinine or artesunate (from 2nd trimester)
Implementation of the new policy • In 2002/2003 ACT was firstly introduced and closely followed up in 3 southern provinces of Laos: Attopeu, Sekong and Saravane where mortality and morbidity to malaria are high and evidence of DR is available. • Implementation of ACT focuses on provincial and district hospitals including health centers. • In pilot areas it is also implemented down to village level. • In 2005, begin of countrywide implementation
Efficacy monitoring of new policy continues in the 3 Lao sentinel sites, and regular review of results will be conducted • As the combination is expensive (2.4US$ per adult dose) therefore it is required to perform a malaria test (microscopy or dipstick) and treatment is given only to P.f positive patient
