OBJECTIVES: The recommended microscopy method by WHO to quantify malaria parasitaemia yields inaccurate results when individual leukocyte (WBC) counts deviate from 8000 leukocytes/μL. A method avoiding WBC count assumptions is the Lambaréné method. Thus, this study compared validity and reliability of the Lambaréné method and the WHO method. METHODS: Three methods for counting parasitaemia were applied in parallel in a blinded assessment: the Lambaréné method (LAMBA), the WHO method using a standard factor of 8000 leukocytes/μL ("simple WHO method", [sWHO]) and the WHO method using measured WBC counts ("accurate WHO method", [aWHO])...

OBJECTIVE: The 2015 WHO recommendation to initiate all HIV patients on antiretroviral therapy (ART) at diagnosis could potentially overextend health systems and crowd out sicker patients, mitigating the policy's impact. We evaluate whether South Africa's prior eligibility expansion from CD4 ≤200 to CD4 ≤350 cells/μL reduced ART uptake in the sickest patients. METHODS: Using data on all patients presenting to the Hlabisa HIV Treatment and Care Program in KwaZulu-Natal from April 2010 - June 2012 (n=13,809), we assessed the impact of the August 2011 eligibility expansion on the number of patients seeking care, number initiating ART, and time from HIV diagnosis to ART initiation among patients always eligible (CD4 0-200), newly eligible (CD4 201-350), and not yet eligible by CD4 count (>350)...

OBJECTIVES: Tuberculosis (TB) is known as a disease of the poor. Despite TB diagnosis and care usually being offered for free, TB patients can still face substantial costs, especially in the context of multi-drug resistance (MDR). The End TB Strategy calls for zero TB-affected families incurring 'catastrophic' costs due to TB by 2025. This paper examines, by MDR status, the level and composition of costs incurred by TB-affected households during care seeking and treatment; assesses the affordability of TB care using catastrophic and impoverishment measures; and describes coping strategies used by TB-affected households to pay for TB care...
