Paediatric Care and treatment: What do we know What needs to be done?
Lack of attention to children- What do we need to consider in this consultation? • Children are not little adults and the guidelines need that specificity • Disease more aggressive in children – 30% mortality at yr 1, 50% at yr 2 and 60% at yr 5 – aspects of early diagnosis to be considered • HIV Diagnosis for children below 18 months problematic: • Clinical disease presentation non-specific • PCR expensive and requires sophisticated labs and expertise • Laboratory monitoring in children under 6 years difficult –CD4% required for children below 6 years • Capacities and expertise on care and treatment underdeveloped • Lack of infrastructure for chronic care management of children
Early diagnosis of HIV infection Ensure reliable early diagnosis of HIV infected children: • Ensure specialized care for infected children • Discontinue PCP prophylaxis in uninfected children • DNA PCR (real time PCR) on Dried Blood Spots (on filter paper) performed in regional/national centers?

What should be our guiding principles? • Urgency. There is an immediate need to scale up diagnosis and treatment. To achieve this guidelines should consider what can be delivered at the lower levels and different practitioners. • Equity of Access. All children in need of treatment, care, and support, including the hard to reach will receive it. • The Centrality of the needs Children Living with HIV/AIDS. The needs of children living with HIV/AIDS and their caregivers within the broader context of child survival. • Delivery of Life-Long Care and Support. Once started, antiretroviral therapy is for life. Recommendations should be realistic to ensure uninterrupted medicine supply.
Procurement and Supplies Management PMTCT Scale Up What tools do we have ?
FORMULATIONS TO PROVIDE PMTCT SERVICES : Key challenges • Nevirapine tablets: • Commercially available as pack of 60 tablets • Blister packs facilitate dispensing to some extent • For PMTCT, need 1 tablet stat, often to take home ? • Nevirapine suspension (10mg/ml): • Commercially available as 240ml • Donation programmes supply 20ml or 25ml • For PMTCT, need 0,6ml per day ? • Commercial bottles are adapted with fitted caps to facilitate dispensing, donation to decant ? • Dispensing syringe : BAXA Donation
FORMULATIONS TO PROVIDE PMTCT SERVICES : Key challenges • zidovudine tablets: bd from 28 weeks • Commercially available as pack of 60 tablets • Blister packs facilitate dispensing to some extent • zdv 300mg/3TC 150mg tablets: intrapartum, bd 7 days • Commercially available as pack of 60 tablets • Blister packs facilitate dispensing to some extent • For PMTCT, need 16 – 18 tablets per week, 20’s pack ? • zidovudine oral liquid (10mg/ml) • Commercially available as 100ml, 200ml, 240ml bottle • For PMTCT, need approximately 35 – 50 ml per week, or • 150ml per month ( if mom had no ART ) ?
Procurement and Supplies Management Paediatric HIC Care and Support
Global technical tools available .. • 2006 ART treatment guidelines for paediatric and adult ART; and ARVs for PMTCT (2004) • Guidelines on care treatment and support of HIV infected women and their children(nutrition, diagnosis, care of HIV exposed and infected children) • Global strategy on infant and young child feeding (range of tools) • Expert recommendations on Appropriate Paediatric ARV Formulations

MSF PAPER 2004: Current situation regarding prices and availability of specific children formulations … • Cost of treatment drops when switching to adult formulations: Peak around 14kg bodyweight • Using tablets for a child (20 kg) reduces the cost per treatment per year nearly 8 times: • (d4T / 3TC / NVP ) Best generic price/y $ 566 $224 Best innovator price/y $1,706 $631 • Managing the switch – increases complexities in resource poor settings
WHAT IS NEW ?WHO 6th Expression of Interest spells it out • Single formulations, adults, adolescents, paeds: • NRTIs; ABC, ddI, 3TC, d4T, TDF, ZDV • NNRTIs ; NVP, EFV • PIs; IDV, NFV, SQV, rtv • Reduced doses, scored tablets for the young, liquid formulation • FDC for adults and paeds, scored • Co-packaged formulations for adults and kids
Procurement and Supplies Management The need for Optimising Supply and Demand
Challenges affecting supply strategies supporting global disease programmes • Product selection is driven working groups, consultants and prequalification efforts • Lack of consideration of product specifications, e.g. expiry dates, weights and volume • Lack of consideration of storage and distribution requirements • Lack of consideration of performance characteristics, e.g. refrigeration needs • Lack of consideration of costs and cost drivers, buffer stock • Push to place orders to reach programme targets
Challenges affecting supply strategies supporting global disease programmes • Traditional planning methods are focussed on pushing products downstream towards end users, rarely with an understanding of the true demand at the first level of care • Push to place orders • Items move from under-stock to overstock in no time, expire, move back to undersupply Erratic demand • Affecting private sector as much as public
Delivery Systems & Management structures drive supply and demand • Unclear scientific data on effective models for delivery of paediatric care in resource limited settings • Chronic care management of sick children limited in most settings • However, best practices from programmatic experiences are emerging
