Admission Characteristics, Diagnoses And Outcomes Of HIV-Infected Patients Registered In An Ambulatory HIV-Care Programme In Western Kenya

Objective: To determine admissions diagnosis and outcomes of HIV-infected patients attending AMPATH ambulatory HIV-care clinics. Design: Prospective cohort study. Setting: Academic Model for Prevention and Treatment of HIV/ AIDS (AMPATH) ambulatory HIV-care clinic in western Kenya. Results: Between January 2005 and December 2006, 495 HIV-infected patients enrolled in AMPATH were admitted. Median age at admission was 38 years (range: 19 - 74), 62% females, 375 (76%) initiated cART a median 56 days (range: 1- 1288) before admission. Majority (53%) had pre-admission CD4 counts 200 cells/ml. Common admissions diagnoses were: tuberculosis (27%); pneumonia (15%); meningitis (11%); diarrhoea (11%); malaria (6%); severe anaemia (4%); and toxoplasmosis (3%). Deaths occurred in 147 (30%) patients who enrolled at AMPATH a median 44 days (range: 1 - 711) before admission and died a median 41 days (range: 1 -713) after initiating cART. Tuberculosis (27%) and meningitis (14%) were the most common diagnoses in the deceased. Median admission duration was six days (range: 1 - 30) for deceased patients and eight days (range: I - 44) for survivors (P=0.0024). Deceased patients enrolled in AMPATH or initiated cART more recently, had lower CD4 counts and were more frequently lost to follow-up than survivors (

A Needs Assessment to Build International Research Ethics Capacity at Moi University

International Research Ethics Partnership. This online version is the post-print version (final, peer-reviewed and accepted for publication version) of the published article. For the published version, refer to the article citation within the item record.International collaborators in biomedical sciences face ethical challenges in the design,review, and conduct of research. Challenges include differences in research ethics capacity, cultural differences in interpretation and application of ethical principles, and cooperation between ethics review boards at collaborating institutions. Indiana University School of Medicine (Indianapolis, USA) and Moi University Faculty of Health Sciences (Eldoret, Kenya)developed a Memorandum of Understanding (MOU) to establish greater cooperation between their ethics review boards, followed by a joint needs assessment to assess barriers to implementing the MOU. Focus groups and interviews at each institution revealed that while each side verbalized understanding and respect for the other's culture, there were misunderstandings deeply rooted in each culture that could potentially derail the collaboration. Although the participants at each university agreed on the major principles and issues in research ethics and on the importance attributed to them, a more in-depth evaluation of the responses revealed important differences. Methods to address these misunderstandings are outlined in the recommended Best Practices.Fogarty International Center at the NIH, Indiana University Division of General Internal Medicine and Geriatrics, Indiana University School of Medicine, Indiana University International Development Fund, Indiana Genomics Initiative, Lilly Endowment, Inc

Triangulating’ AMPATH: Demonstration of a multi-perspective strategic programme evaluation method

Clinical programmes are typically evaluated on operational performance metrics of cost, quality and outcomes. Measures of patient satisfaction are used to assess the experience of receiving care, but other perspectives, including those of staff and communities, are not often sought or used to assess and improve programmes. For strategic planning, the Kenyan HIV/AIDS programme AMPATH (Academic Model Providing Access to Healthcare) sought to evaluate its performance in 2006. The method used for this evaluation was termed ‘triangulation,’ because it used information from three different sources – patients, communities, and programme staff. From January to August 2006, Indiana University external evaluators and AMPATH staff gathered information on strengths, weaknesses and suggestions for improvement of AMPATH. Activities included in-depth key-informant semi-structured interviews of 26 AMPATH clinical and support staff, 56 patients at eight clinic sites, and seven village health dialogues (mabaraza) at five sublocations within the AMPATH catchment area. Data sources included field notes and transcripts of translated audio recordings,which were subjected to qualitative content analysis. Eighteen  recommendations for programme improvement emerged, including ten from all three respondent perspectives. Three recommendations were cited by patients and in mabaraza, but not by staff. Triangulation uncovered improvement emphases that an internal assessment would miss. AMPATH and Kenyan Ministry of Health leadership have deliberated these recommendations and accelerated strategic change actions, including rural satellite programmes, collaboration with village-based workers, and door-to-door village-based screening and counselling

Task Shifting in HIV Clinics, Western Kenya

Background: United states Agency for International development-Academic Model for Providing Accesses to Healthcare (USAID-AMPATH) cares for over 80,000 HIVinfected patients. Express care (EC) model addresses challenges of: clinically stable patient’s adherent to combined-antiretroviral-therapy with minimal need for clinician intervention and high risk patients newly initiated on cART with CD4 counts ≤100 cells/mm3 with frequent need for clinician intervention. Objective: To improve patient outcomes without increasing clinic resources. Design: A descriptive study of a clinician supervised shared nurse model. Setting: USAID-AMPATH clinics, Western Kenya. Results: Four thousand eight hundred and twenty four patients were seen during the pilot period, 90.4% were eligible for EC of whom 34.6% were enrolled. Nurses performed all traditional roles and attended to two thirds and three quarters of stable and high risk patient visits respectively. Clinicians attended to one third and one quarter of stable and high risk patient visits respectively and all visits ineligible for express care. Conclusion: The EC model is feasible. Task shifting allowed stable patients to receive visits with nurses, while clinicians had more time to concentrate on patients that were new as well as more acutely ill patients.East African Medical Journal Vol. 87 No. 7 July 201

Risk factors for death in HIV-infected adult african patients recieving anti-retroviral therapy

Objective: To determine risk factors for death in HIV-infected African patients on anti-retroviral therapy (ART).Design: Retrospective Case-control study.Setting: The MOH-USAID-AMPATH Partnership ambulatory HIV-care clinics in western Kenya.Results: Between November 2001 and December 2005 demographic, clinical and laboratory data from 527 deceased and 1054 living patients receiving ART were compared to determine independent risk factors for death. Median age at ART initiation was 38 versus 36 years for the deceased and living patients respectively (p<0.0148). Mediantime from enrollment at AMPATH to initiation of ART was two weeks for both groups while median time on ART was eight weeks for the deceased and fourty two weeks for the living (p<0.0001). Patients with CD4 cell counts <100/mm3 were more likely to die than those with counts >100/mm3 (HR=1.553. 95% CI (1.156, 2.087), p<0.003). Patientsattending rural clinics had threefold higher risk of dying compared to patients attending clinic at a tertiary referral hospital (p<0.0001). Two years after initiating treatment fifty percent of non-adherent patients were alive compared to 75% of adherent patients. Male gender, WHO Stage and haemoglobin level <10 grams% were associated with time to death while age, marital status, educational level, employment status andweight were not.Conclusion: Profoundly immunosuppressed patients were more likely to die early in the course of treatment. Also, patients receiving care in rural clinics were at greater risk of dying than those receiving care in the tertiary referral hospital

Pathogenic Huntingtin Repeat Expansions in Patients with Frontotemporal Dementia and Amyotrophic Lateral Sclerosis.

We examined the role of repeat expansions in the pathogenesis of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) by analyzing whole-genome sequence data from 2,442 FTD/ALS patients, 2,599 Lewy body dementia (LBD) patients, and 3,158 neurologically healthy subjects. Pathogenic expansions (range, 40-64 CAG repeats) in the huntingtin (HTT) gene were found in three (0.12%) patients diagnosed with pure FTD/ALS syndromes but were not present in the LBD or healthy cohorts. We replicated our findings in an independent collection of 3,674 FTD/ALS patients. Postmortem evaluations of two patients revealed the classical TDP-43 pathology of FTD/ALS, as well as huntingtin-positive, ubiquitin-positive aggregates in the frontal cortex. The neostriatal atrophy that pathologically defines Huntington's disease was absent in both cases. Our findings reveal an etiological relationship between HTT repeat expansions and FTD/ALS syndromes and indicate that genetic screening of FTD/ALS patients for HTT repeat expansions should be considered
