- ItemOpen AccessAssessment at antiretroviral clinics during TB treatment reduces loss to follow-up among HIV-infected patients(Public Library of Science, 2012) Pepper, Dominique J; Marais, Suzaan; Bhaijee, Feriyl; Wilkinson, Robert J; De Azevedo, Virginia; Meintjes, GraemeSetting: A South African township clinic where loss to follow-up during TB treatment may prevent HIV-infected TB patients from receiving life-saving ART. Objective: To determine factors associated with loss to follow-up during TB treatment. Design: Regression analyses of a cohort of ART-eligible TB patients who commenced TB treatment and were followed for 24 weeks. RESULTS: Of 111 ART-eligible TB patients, 15 (14%) died in the ensuing 24 weeks. Of the remaining 96 TB patients, 11 (11%) were lost to follow-up. All TB patients lost to follow-up did not initiate ART. Of 85 TB patients in follow-up, 62 (73%) initiated ART 56 days after TB diagnosis (median, IQR 33-77 days) and 31 days after initial assessment at an ART clinic (median, IQR: 18-55 days). The median duration from TB diagnosis to initial assessment at an ART clinic was 19 days (IQR: 7-48 days). At 24 weeks, 6 of 85 (7%) TB patients who presented to an ART clinic for assessment were lost to follow-up, compared to 5 of 11 (45%) TB patients who did not present to an ART clinic for assessment. Logistic regression analysis (adjusted odds ratio  = 0.1, 95% confidence interval [95% CI]: 0.03-0.66) and our Cox proportional hazards model (hazard ratio  = 0.2, 95% CI: 0.04-0.68) confirmed that assessment at an ART clinic during TB treatment reduced loss to follow-up. CONCLUSION: Assessment at antiretroviral clinics for HIV care by trained health-care providers reduces loss to follow-up among HIV-infected patients with TB.
- ItemOpen AccessBarriers to initiation of antiretrovirals during antituberculosis therapy in Africa(Public Library of Science, 2011) Pepper, Dominique J; Marais, Suzaan; Wilkinson, Robert J; Bhaijee, Feriyl; De Azevedo, Virginia; Meintjes, GraemeBACKGROUND: In the developing world, the principal cause of death among HIV-infected patients is tuberculosis (TB). The initiation of antiretroviral therapy (ART) during TB therapy significantly improves survival, however it is not known which barriers prevent eligible TB patients from initiating life-saving ART. Method Setting. A South African township clinic with integrated tuberculosis and HIV services. Design. Logistic regression analyses of a prospective cohort of HIV-1 infected adults (≥18 years) who commenced TB therapy, were eligible for ART, and were followed for 6 months. FINDINGS: Of 100 HIV-1 infected adults eligible for ART during TB therapy, 90 TB patients presented to an ART clinic for assessment, 66 TB patients initiated ART, and 15 TB patients died. 34% of eligible TB patients (95%CI: 25-43%) did not initiate ART. Male gender and younger age (<36 years) were associated with failure to initiate ART (adjusted odds ratios of 3.7 [95%CI: 1.25-10.95] and 3.3 [95%CI: 1.12-9.69], respectively). Death during TB therapy was associated with a CD4+ count <100 cells/µL. CONCLUSION: In a clinic with integrated services for tuberculosis and HIV, one-third of eligible TB patients - particularly young men - did not initiate ART. Strategies are needed to promote ART initiation during TB therapy, especially among young men.
- ItemOpen AccessClinical deterioration during antituberculosis treatment in Africa: Incidence, causes and risk factors(BioMed Central Ltd, 2010) Pepper, Dominique; Marais, Suzaan; Wilkinson, Robert; Bhaijee, Feriyl; Maartens, Gary; McIlleron, Helen; De Azevedo, Virginia; Cox, Helen; McDermid, Cheryl; Sokhela, Simiso; Patel, Janisha; Meintjes, GraemeBACKGROUND:HIV-1 and Mycobacterium tuberculosis cause substantial morbidity and mortality. Despite the availability of antiretroviral and antituberculosis treatment in Africa, clinical deterioration during antituberculosis treatment remains a frequent reason for hospital admission. We therefore determined the incidence, causes and risk factors for clinical deterioration. METHODS: Prospective cohort study of 292 adults who initiated antituberculosis treatment during a 3-month period. We evaluated those with clinical deterioration over the following 24 weeks of treatment. RESULTS: Seventy-one percent (209/292) of patients were HIV-1 infected (median CD4+: 129 cells/muL [IQR:62-277]). At tuberculosis diagnosis, 23% (34/145) of HIV-1 infected patients qualifying for antiretroviral treatment (ART) were receiving ART; 6 months later, 75% (109/145) had received ART. Within 24 weeks of initiating antituberculosis treatment, 40% (117/292) of patients experienced clinical deterioration due to co-morbid illness (n = 70), tuberculosis related illness (n = 47), non AIDS-defining HIV-1 related infection (n = 25) and AIDS-defining illness (n = 21). Using HIV-1 uninfected patients as the referent group, HIV-1 infected patients had an increasing risk of clinical deterioration as CD4+ counts decreased [CD4+>350 cells/muL: RR = 1.4, 95% CI = 0.7-2.9; CD4+:200-350 cells/muL: RR = 2.0, 95% CI = 1.1-3.6; CD4+<200 cells/muL: RR = 3.0, 95% CI = 1.9-4.7]. During follow-up, 26% (30/117) of patients with clinical deterioration required hospital admission and 15% (17/117) died. Fifteen deaths were in HIV-1 infected patients with a CD4+<200 cells/muL. CONCLUSIONS: In multivariate analysis, HIV-1 infection and a low CD4+ count at tuberculosis diagnosis were significant risk factors for clinical deterioration and death. The initiation of ART at a CD4+ count of <350 cells/muL will likely reduce the high burden of clinical deterioration.
- ItemOpen AccessFibrolamellar hepatocellular carcinoma at a tertiary centre in South Africa(Health and Medical Publishing Group, 2009) Bhaijee, Feriyl; Locketz, Michael L; Krige, Jake E JBackground: Fibrolamellar carcinoma (FLC) is an uncommon malignant tumour of hepatocyte origin that differs from hepatocellular carcinoma (HCC) in aetiology, demographics, condition of the affected liver, and tumour markers. Controversy exists whether FLC demonstrates a more favourable prognosis than typical HCC. A review of existing literature reveals a dearth of FLC data from the African continent. Methods: We utilised the prospective liver resection database at Groote Schuur Hospital to identify all patients who underwent surgery for FLC between 1990 and 2008. Results: Seven patients (median age 21 years, range 19 - 42, 5 men, 2 women) underwent surgery for FLC. No patient had underlying liver disease or an elevated alpha fetoprotein (AFP) at either initial presentation or recurrence. Six patients had a solitary tumour at diagnosis (mean largest diameter = 12cm), and underwent left hepatectomy (N=2), right hepatectomy (N=1), extended right hepatectomy (N=1), and segmentectomies (N=2). Three patients underwent a portal lymphadenectomy for regional lymphatic tumour involvement. One patient with advanced extrahepatic portal nodal metastasis was unresectable. No peri-operative deaths occurred. Recurrence occurred post resection in all 6 patients. Median overall survival was 60 months, and overall 5-year survival was 4 out of 7 (57%). Post-resection survival (N=6) was 61 months, with a 5-year survival rate of 4 out of 6 (67%). The patient with unresectable disease survived 38 months after tumour embolisation with Lipiodol. Conclusion: Our series suggests that despite (i) a high resection rate of solitary lesions with clear tumour resection margins, and (ii) absence of underlying liver disease, FLC has a high recurrence rate with an ultimately poor clinical outcome. These findings concur with recent international experience of FLC.
