Prevalence of clinical, immunological and irological failure among children on Haart at the university teaching hospital, Lusaka, Zambia

Background: There is increasing evidence that the current clinical and immunological monitoring tools are not sufficient to identify early enough patients who are failing on treatment. Development of resistance to the limited treatment options for children and premature switching are the dangers. The objective of this study was to review patient records to see how well WHO staging, CD4 profiles and viral load estimations relate in children on treatment at the University Teaching Hospital (UTH).Methods: A retrospective chart review of all children aged between 0-19 years that started treatment between January 2004 and Dec 2010 was carried out at the UTH. Systematic sampling was done of every second child who received HAART for more than 24 weeks, with at least one viral load (VL) reading beyond 24 weeks of treatment. Six-monthly clinical (WHO staging) immunological (age- related CD4 count/%) and virological data were collected until last follow-up review or five years on treatment. The 2010 Zambian Pediatric Guidelines were used to gauge age-related clinical, immunological and virological failure (VL> 1,000).Results: A total of 517 patient records were reviewed (table 1). Mean age at ART initiation was 7 years ((SD 4.7yrs). Mean time after ART initiation when first viral load test was done was 2.7 years (SD 1.5yrs). Of all the viral loads done, 64% (328) had a routine indication for patients on treatment nearing the 3 year mark (mean 2.7 years). In 40% of children the first viral load test result was above 1,000 after 24 weeks or more of treatment. A total of 482 patients had WHO staging done at the time first VL test was done. Of the 359 patients (table 2) with a clinical stage I/II (not severely immunosuppressed), 41% were failing virologically. On the other hand, 63% of the patients with clinical stage III/IV had a VL below 1,000. Table 3 shows that there were 509 patients who had an immunological staging done at the time first VL was done. Of the 106 patients who were failing immunologically, 28% were virologically well suppressed. On the other hand of the 403 who were immunologically doing fine, 32% were failing virologically.Conclusions: Clinical staging and Immunological monitoring in children on ART does not accurately identify those that are failing. A push for routine, affordable virological testing is needed to identify treatment failures early to prevent development of ART resistance and to avoid premature switches to second line in those who are actually well suppressed

2017 ACC/AHA/HFSA/ISHLT/ACP Advanced Training Statement on Advanced Heart Failure and Transplant Cardiology (Revision of the ACCF/AHA/ACP/HFSA/ISHLT 2010 Clinical Competence Statement on Management of Patients With Advanced Heart Failure and Cardiac Transplant)

Since the 1995 publication of its Core Cardiovascular Training Statement (COCATS),1 the American College of Cardiology (ACC) has played a central role in defining the knowledge, experiences, skills, and behaviors expected of all clinical cardiologists upon completion of training. Subsequent updates have incorporated major advances and revisions—both in content and structure—including, most recently,

Acceptability of HIV counselling and testing among tuberculosis patients in south Ethiopia

<p>Abstract</p> <p>Background</p> <p>To benefit from available care and treatment options, patients should first be counselled and tested for HIV. Our aim was to assess the acceptability of HIV testing among tuberculosis patients under routine care conditions in south Ethiopia.</p> <p>Methods</p> <p>We interviewed all adult tuberculosis patients who were treated at Arba Minch Hospital in Ethiopia between January and August 2005. After recording socio-demographic information and tuberculosis treatment history, we referred those patients who showed initial willingness to a counsellor for HIV counselling and testing. Rapid test methods were used following a pretest counselling session. The results were disclosed during a post-test counselling session. We used the logistic regression method to assess factors associated with willingness and acceptability.</p> <p>Results</p> <p>190 adult tuberculosis patients were treated at the hospital and all of them consented to take part in the study. Their median age was 30 years (range, 15–68) and 52% of them were males. 49 patients (26%) were previously tested including 29 (59%) HIV positive. Of 161 patients (excluding the 29 already positive), 118 (73%) were willing to be tested and 58% (68/118) of those willing accepted the test. The overall acceptability rate was 35% (56/161). Fourteen (20.6%) were HIV positive and women were more likely to be HIV infected (p = 0.029). Unemployment and self-perceived high risk of HIV infection were associated with initial willingness (OR [95%CI]:2.6 [1.3–5.5] vs. 5.0 [1.1–22.4], respectively). However, only being unemployed was associated with accepting the test (OR = 4.2; 95%CI = 1.9–9.3).</p> <p>Conclusion</p> <p>The low acceptability of HIV counselling and testing among tuberculosis patients poses a challenge to the scale-up of TB/HIV collaborative efforts. There is a need for alternative counselling and testing strategies.</p

Knowledge and Perceptions of Couples' Voluntary Counseling and Testing in Urban Rwanda and Zambia: A Cross-Sectional Household Survey

Most incident HIV infections in sub-Saharan Africa occur between cohabiting, discordant, heterosexual couples. Though couples' voluntary HIV counseling and testing (CVCT) is an effective, well-studied intervention in Africa, <1% of couples have been jointly tested.We conducted cross-sectional household surveys in Kigali, Rwanda (n = 600) and Lusaka, Zambia (n = 603) to ascertain knowledge, perceptions, and barriers to use of CVCT.Compared to Lusaka, Kigali respondents were significantly more aware of HIV testing sites (79% vs. 56%); had greater knowledge of HIV serodiscordance between couples (83% vs. 43%); believed CVCT is good (96% vs. 72%); and were willing to test jointly (91% vs. 47%). Stigma, fear of partner reaction, and distance/cost/logistics were CVCT barriers.Though most respondents had positive attitudes toward CVCT, the majority were unaware that serodiscordance between cohabiting couples is possible. Future messages should target gaps in knowledge about serodiscordance, provide logistical information about CVCT services, and aim to reduce stigma and fear

Promotion of couples' voluntary counselling and testing for HIV through influential networks in two African capital cities

<p>Abstract</p> <p>Background</p> <p>Most new HIV infections in Africa are acquired from cohabiting heterosexual partners. Couples' Voluntary Counselling and Testing (CVCT) is an effective prevention strategy for this group. We present our experience with a community-based program for the promotion of CVCT in Kigali, Rwanda and Lusaka, Zambia.</p> <p>Methods</p> <p>Influence Network Agents (INAs) from the health, religious, non-governmental, and private sectors were trained to invite couples for CVCT. Predictors of successful promotion were identified using a multi-level hierarchical analysis.</p> <p>Results</p> <p>In 4 months, 9,900 invitations were distributed by 61 INAs, with 1,411 (14.3%) couples requesting CVCT. INAs in Rwanda distributed fewer invitations (2,680 vs. 7,220) and had higher response rates (26.9% vs. 9.6%), than INAs in Zambia. Context of the invitation event, including a discreet location such as the INA's home (OR 3.3–3.4), delivery of the invitation to both partners in the couple (OR 1.6–1.7) or to someone known to the INA (OR 1.7–1.8), and use of public endorsement (OR 1.7–1.8) were stronger predictors of success than INA or couple-level characteristics.</p> <p>Conclusion</p> <p>Predictors of successful CVCT promotion included strategies that can be easily implemented in Africa. As new resources become available for Africans with HIV, CVCT should be broadly implemented as a point of entry for prevention, care and support.</p
