HIV/AIDS programmeHaydom Lutheran Hospital
• Voluntary counselling and testing (VCT)– Local hospital initiative
– NORAD supported project from 2002 planned in collaboration with Centre for International Health, Bergen
• HIV treatmentProject planned and supported by:
– Ullevål University Hospital, Oslo
– Sørlandet Hospital, Kristiansand
– NORAD support for drugs
JNB/05
Necessary conditions for starting HAART
• HIV-testing and counselling (VCT)– Established through NORAD project early 2003
• Diagnostic procedures– Evaluation of immunodeficiency – CD4 cell counts– Diagnosis of opportunistic infections / WHO stage III-IV
or CDC stage B (ARC) – C (AIDS)– Laboratory tests necessary for treatment follow up –
detection of serious side effects
• Drug supply– Antiretroviral drugs– Drugs for treatment of opportunistic infections
• Free treatment• Clinical skills for evaluation of patients
JNB/05
Problems with antiviral therapy
• A combination of drugs have to be taken every day – To be continued even if patient feels well
• Development of resistance – Insufficient drug combinations
– Lack of adherence
• Side effects
JNB/05
Adherence problems• Insufficient understanding of the
disease, the effect of treatment and the risk of resistance
• Stigma – lack of openness towards family and surrounding society – lack of acceptance
• Side effects
• Difficulties with drug supply
• Follow up
• Problems with care and nutrition
JNB/05
Problems with follow up
• Long distance from hospital
• Cost of travel
• No one to care for family at home
• No one to provide food in hospital
• Stop of treatment and follow up when improved
JNB/05
Indications for starting HAART
• Pregnancy in order to prevent HIV transmission to the child
• Development of laboratory signs of immunodeficiency– CD4-cell count < 200x109/L
• Symptomatic disease - Clinical signs of immunodeficiency– AIDS – CDC clinical stage C disease or WHO stage
4 disease
– ARC (AIDS Related Complex) - CDC clinical stage B disease or WHO stage 3 disease
JNB/05
DOT – Directly Observed Therapy in HAART treatment
Modified DOT regimen
• Initial phase – 14 days– Outpatients attend the HIV outpatient clinic once daily. The first
daily dose to be taken at clinic – the second dose delivered to the patient to be taken in the evening
– Blood sample at day 14
• Initial phase - week 3 and 4– Patients are given drugs for one week at the time – return of the
bottle for pill count and new drugs once a week
– Blood sample at day 28
• Continuation phase– Patients are given drug for 4-5 weeks – return with the bottles
for pill count and new drugs every 4 weeks
– Blood sample at week 12 and then every 3 months

Preliminary results
01.01.2005 01.05.2005
• Evaluated patients 152 300
• Started on CART 128 139
• Deaths 35 50
• Lost to follow up 9
CART: Combination antiretroviral therapy

Differences between the Haydom project and relief projects by MSF
Haydom:• All patients with
established treatment indications offered treatment
• Patients newly started on treatment for opportunistic infections included
• No selection based on long time follow up before treatment start
• Patients included even if no disclosure of HIV-status to others
MSF-Malawi (Thyolo):• Well developed home
based care system• Thorough screening of
patients for treatment• Exclusion of patients:
– Active opportunistic infections
– Not able to attend follow up regularly for several weeks prior to inclusion
– Not willing to disclose their HIV-status to family and contact persons in village
JNB/05
Consequences of the differences between the programs at Haydom and
MSF-Malawi
Haydom:• All patients needing
treatment are offered treatment
• Difficulties with follow up due to – Lack of transport– Stigmatisation HIV-status not
shared with relatives
• High death rate due to– Nutritional problems– Opportunistic infections
• Resistance may develop due to poor adherence to treatment
• The program may be run by local health personnel
MSF-Malawi:• Good adherence to
treatment• Few lost to follow up• Low death rate among
those treated• Selection criteria favours
people with abundant economical and mental resources
• Higher cost per patient treated
• The program depends on extensive continued support
JNB/05
Improvements
• Provision of transport to hospital
• Follow up seminars for patients every 4-8 weeks
• Mobile clinics – outreach program for follow up and drug delivery to patients at nearby village
• Nutritional support program for both in- and out-patients
JNB/05
ConclusionMain challenges
• Education and motivation of patients
• Stigma and acceptance of the disease
• Necessary laboratory service
• Qualified health personnel
• Follow up – transport from remote villages
• Drug supply
• Government regulations
JNB/05
HIV-treatment programs in developing countries
• Research projects– Completely staffed by skilled personnel
– Supply of modern equipment
– Run for a limited period
– Long term effect on local health service??
• Relief projects– Necessary skilled personnel brought in
– Some training of local staff
– Strictly necessary equipment
– Depend on continued support
• Development projects– Key personnel for limited periods
– Training of local staff aimed at take over
– Strictly necessary equipment
