Growth response to antiretroviral treatment in HIV-infected children: a cohort study from Lilongwe, Malawi.

OBJECTIVE: Malnutrition is common in HIV-infected children in Africa and an indication for antiretroviral treatment (ART). We examined anthropometric status and response to ART in children treated at a large public-sector clinic in Malawi. METHODS: All children aged <15 years who started ART between January 2001 and December 2006 were included and followed until March 2008. Weight and height were measured at regular intervals from 1 year before to 2 years after the start of ART. Sex- and age-standardized z-scores were calculated for weight-for-age (WAZ) and height-for-age (HAZ). Predictors of growth were identified in multivariable mixed-effect models. RESULTS: A total of 497 children started ART and were followed for 972 person-years. Median age (interquartile range; IQR) was 8 years (4-11 years). Most children were underweight (52% of children), stunted (69%), in advanced clinical stages (94% in WHO stages 3 or 4) and had severe immunodeficiency (77%). After starting ART, median (IQR) WAZ and HAZ increased from -2.1 (-2.7 to -1.3) and -2.6 (-3.6 to -1.8) to -1.4 (-2.1 to -0.8) and -1.8 (-2.4 to -1.1) at 24 months, respectively (P < 0.001). In multivariable models, baseline WAZ and HAZ scores were the most important determinants of growth trajectories on ART. CONCLUSIONS: Despite a sustained growth response to ART among children remaining on therapy, normal values were not reached. Interventions leading to earlier HIV diagnosis and initiation of treatment could improve growth response.

Early active follow-up of patients on antiretroviral therapy (ART) who are lost to follow-up: the 'Back-to-Care' project in Lilongwe, Malawi.

OBJECTIVES: To determine the proportion of patients returning to antiretroviral treatment (ART) and factors associated with their return in a resource-limited setting. METHODS: Between September 2006 and March 2009, at two ART-providing facilities in Lilongwe, Malawi, we identified patients who had missed clinic appointments by more than 3 weeks and therefore would have run out of antiretroviral drugs. We traced these individuals, documented reasons for missed appointments and, where appropriate, arranged another ART clinic appointment. RESULTS: Between April 2006 and March 2009, 2653 patients on ART had missed 3098 scheduled appointments. We successfully traced 85%, of whom 30% had died. Of the 1580 patients found alive, 25% had transferred to another ART clinic, 21% had collected drugs from other sources, 11% had treatment gaps; 40% had stopped taking drugs, 1% had not started taking drugs despite collecting them and 2% refused to be interviewed. Of the 1158 LTFU patients who had not died, transferred out or declined to be interviewed, 89% promised to return to their ART clinic and 74% actually did. The probability of returning to the clinic was significantly associated with being women, aged over 39 at ART initiation and having either treatment gaps or uninterrupted therapy. The B2C project reduced the proportion of patients finally classified as LTFU by 59%. CONCLUSION: Early active follow-up of LTFU patients resulted in marked improvement in known patient outcomes and improved retention in the treatment programme.

Developing a palliative care service for children in the Queen Elizabeth Central Hospital, Blantyre, Malawi.

There are too few palliative care services for children in resource poor countries. Health carers are overwhelmed with cases of acute illness that need their urgent attention, and chronically ill children with life-limiting diseases have been sidelined. The HIV epidemic in southern Africa revealed the huge needs in our own hospital, and in 2002, we started a hospital-based paediatric palliative care service. It was the first in Africa. We describe here how it developed and expanded in the ensuing years and how it has affected our staff, the children and their families in our care.
