ABSTRACT

BACKGROUND: Across sub-Saharan Africa, mid-level healthcare managers oversee implementation of national guidelines. It remains unclear whether leadership and management training can improve population health outcomes. METHODS: We sought to evaluate leadership/management skills among district-level health managers in Uganda participating in the SEARCH-IPT randomised trial to promote isoniazid preventive therapy (IPT) for persons with HIV (PWH). The intervention, which led to higher IPT rates, included annual leadership/management training of managers. We conducted a cross-sectional survey assessing leadership/management skills among managers at trial completion. The survey evaluated self-reported use of leadership/management tools and general leadership/management. We conducted a survey among a sample of providers to understand the intervention's impact. Targeted minimum loss-based estimation (TMLE) was used to compare responses between trial arms. RESULTS: Of 163 managers participating in the SEARCH-IPT trial, 119 (73%) completed the survey. Intervention managers reported more frequent use of leadership/management tools taught in the intervention curriculum than control managers (+3.64, 95% CI 1.98-5.30, P < 0.001). There were no significant differences in self-reported leadership skills in the intervention as compared to the control group. Among providers, the average reported quality of guidance and supervision was significantly higher in intervention vs control districts (+1.08, 95% CI 0.63-1.53, P = 0.001). CONCLUSIONS: A leadership and management training intervention increased the use of leadership/management tools among mid-level managers and resulted in higher perceived quality of supervision among providers in intervention vs control districts in Uganda. These findings suggest improved leadership/management among managers contributed to increased IPT use among PWH in the intervention districts of the SEARCH-IPT trial.


CONTEXTE: Dans toute l'Afrique subsaharienne, les gestionnaires de soins de santé de niveau intermédiaire supervisent la mise en œuvre des directives nationales. Il n'est toujours pas clair si la formation en leadership et en gestion peut améliorer les résultats en matière de santé de la population. MÉTHODES: Nous avons cherché à évaluer les compétences en leadership et en gestion des responsables de la santé au niveau des districts en Ouganda participant à l'essai randomisé SEARCH-IPT visant à promouvoir le traitement préventif à l'isoniazide (TPI) pour les personnes vivant avec le VIH (PWH, pour l'anglais « people living with HIV ¼). L'intervention, qui a permis d'augmenter les taux de TPI, comprenait une formation annuelle en leadership et en gestion des gestionnaires. Nous avons mené une enquête transversale pour évaluer les compétences en leadership et en gestion des gestionnaires à la fin de l'essai. L'enquête a évalué l'utilisation autodéclarée d'outils de leadership et de gestion et de leadership et de gestion en général. Nous avons mené une enquête auprès d'un échantillon de prestataires pour comprendre l'impact de l'intervention. L'estimation ciblée basée sur les pertes minimales (TMLE, « Targeted minimum loss-based estimation ¼) a été utilisée pour comparer les réponses entre les groupes de l'essai. RÉSULTATS: Sur les 163 gestionnaires qui ont participé à l'essai SEARCH-IPT, 119 (73%) ont répondu au sondage. Les gestionnaires d'intervention ont déclaré utiliser plus fréquemment les outils de leadership/gestion enseignés dans le programme d'intervention que les gestionnaires de contrôle (+3,64 ; IC à 95% 1,98­5,30 ; P < 0,001). Il n'y avait pas de différences significatives dans les compétences de leadership autodéclarées dans l'intervention par rapport au groupe témoin. Parmi les prestataires, la qualité moyenne déclarée de l'orientation et de la supervision était significativement plus élevée dans les districts d'intervention que dans les districts témoins (+1,08 ; IC à 95% 0,63­1,53 ; P = 0,001). CONCLUSIONS: Une intervention de formation au leadership et à la gestion a permis d'accroître l'utilisation d'outils de leadership et de gestion parmi les cadres intermédiaires et d'améliorer la perception de la qualité de la supervision parmi les prestataires dans les districts d'intervention par rapport aux districts de contrôle en Ouganda. Ces résultats suggèrent que l'amélioration du leadership et de la gestion chez les gestionnaires a contribué à l'augmentation de l'utilisation du TPI chez les personnes handicapées dans les districts d'intervention de l'essai SEARCH-IPT.

ABSTRACT

BACKGROUND: Twelve weeks of weekly isoniazid and rifapentine (3HP) prevents TB disease among people with HIV (PWH), but the costs to people of taking TB preventive treatment is not well described.METHODS: We surveyed PWH who initiated 3HP at a large urban HIV/AIDS clinic in Kampala, Uganda, as part of a larger trial. We estimated the cost of one 3HP visit from the patient perspective, including both out-of-pocket costs and estimated lost wages. Costs were reported in 2021 Ugandan shillings (UGX) and US dollars (USD; USD1 = UGX3,587)RESULTS: The survey included 1,655 PWH. The median participant cost of one clinic visit was UGX19,200 (USD5.36), or 38.5% of the median weekly income. Per visit, the cost of transportation was the largest component (median: UGX10,000/USD2.79), followed by lost income (median: UGX4,200/USD1.16) and food (median: UGX2,000/USD0.56). Men reported greater income loss than women (median: UGX6,400/USD1.79 vs. UGX3,300/USD0.93), and participants who lived further than a 30-minute drive to the clinic had higher transportation costs than others (median: UGX14,000/USD3.90 vs. UGX8,000/USD2.23).CONCLUSION: Patient-level costs to receive 3HP accounted for over one-third of weekly income. Patient-centered approaches to averting or defraying these costs are needed.

ABSTRACT

BACKGROUND: Four large community-randomized trials examining universal testing and treatment (UTT) to reduce HIV transmission were conducted between 2012-2018 in Botswana, Kenya, Uganda, Zambia and South Africa. In 2014, the UNAIDS 90-90-90 targets were adopted as a useful metric to monitor coverage. We systematically review the approaches used by the trials to measure intervention delivery, and estimate coverage against the 90-90-90 targets. We aim to provide in-depth understanding of the background contexts and complexities that affect estimation of population-level coverage related to the 90-90-90 targets. METHODS: Estimates were based predominantly on "process" data obtained during delivery of the interventions which included a combination of home-based and community-based services. Cascade coverage data included routine electronic health records, self-reported data, survey data, and active ascertainment of HIV viral load measurements in the field. RESULTS: The estimated total adult populations of trial intervention communities included in this study ranged from 4,290 (TasP) to 142,250 (Zambian PopART Arm-B). The estimated total numbers of PLHIV ranged from 1,283 (TasP) to 20,541 (Zambian PopART Arm-B). By the end of intervention delivery, the first-90 target (knowledge of HIV status among all PLHIV) was met by all the trials (89.2%-94.0%). Three of the four trials also achieved the second- and third-90 targets, and viral suppression in BCPP and SEARCH exceeded the UNAIDS target of 73%, while viral suppression in the Zambian PopART Arm-A and B communities was within a small margin (~ 3%) of the target. CONCLUSIONS: All four UTT trials aimed to implement wide-scale testing and treatment for HIV prevention at population level and showed substantial increases in testing and treatment for HIV in the intervention communities. This study has not uncovered any one estimation approach which is superior, rather that several approaches are available and researchers or policy makers seeking to measure coverage should reflect on background contexts and complexities that affect estimation of population-level coverage in their specific settings. All four trials surpassed UNAIDS targets for universal testing in their intervention communities ahead of the 2020 milestone. All but one of the trials also achieved the 90-90 targets for treatment and viral suppression. UTT is a realistic option to achieve 95-95-95 by 2030 and fast-track the end of the HIV epidemic.

ABSTRACT

Dihydroartemisinin (DHA)-piperaquine is promising for malaria chemoprevention in pregnancy. We assessed the impacts of pregnancy and efavirenz-based antiretroviral therapy on exposure to DHA and piperaquine in pregnant Ugandan women. Intensive sampling was performed at 28 weeks gestation in 31 HIV-uninfected pregnant women, in 27 HIV-infected pregnant women receiving efavirenz, and in 30 HIV-uninfected nonpregnant women. DHA peak concentration and area under the concentration time curve (AUC0-8hr ) were 50% and 47% lower, respectively, and piperaquine AUC0-21d was 40% lower in pregnant women compared to nonpregnant women. DHA AUC0-8hr and piperaquine AUC0-21d were 27% and 38% lower, respectively, in pregnant women receiving efavirenz compared to HIV-uninfected pregnant women. Exposure to DHA and piperaquine were lower among pregnant women and particularly in women on efavirenz, suggesting a need for dose modifications. The study of modified dosing strategies for these populations is urgently needed.

ABSTRACT

Background: Toxicities due to anti-TB treatment frequently occur among TB/HIV-coinfected patients. Objectives: To determine the association between anti-TB drug concentrations and the occurrence of hepatotoxicity and peripheral neuropathy among TB/HIV-coinfected patients. Methods: TB/HIV-coinfected patients were started on standard dose anti-TB treatment according to WHO guidelines. Anti-TB drug concentrations were measured using HPLC 1, 2 and 4 h after drug intake at 2, 8 and 24 weeks following initiation of TB treatment. Participants were assessed for hepatotoxicity using Division of AIDS toxicity tables and for peripheral neuropathy using clinical assessment of tendon reflexes, vibration sensation or symptoms. Cox regression was used to determine the association between toxicities and drug concentrations. Results: Of the 268 patients enrolled, 58% were male with a median age of 34 years. Participants with no hepatotoxicity or mild, moderate and severe hepatotoxicity had a median C max of 6.57 (IQR 4.83-9.41) µg/mL, 7.39 (IQR 5.10-10.20) µg/mL, 7.00 (IQR 6.05-10.95) µg/mL and 3.86 (IQR 2.81-14.24) µg/mL, respectively. There was no difference in the median C max of rifampicin among those who had hepatotoxicity and those who did not ( P = 0.322). There was no difference in the isoniazid median C max among those who had peripheral neuropathy 2.34 (1.52-3.23) µg/mL and those who did not 2.21 (1.45-3.11) µg/mL ( P = 0.49). Conclusions: There was no association between rifampicin concentrations and hepatotoxicity or isoniazid concentrations and peripheral neuropathy among TB/HIV-coinfected patients.

ABSTRACT

BACKGROUND: Implementation of new tuberculosis (TB) diagnostic strategies in resource-constrained settings is challenging. We measured the impact of solid and liquid mycobacterial cultures on treatment practices for patients undergoing TB evaluation in Kampala, Uganda. METHODS: We enrolled consecutive smear-negative, human immunodeficiency virus positive adults with cough of ⩾2 weeks from September 2009 to April 2010. Laboratory technicians performed mycobacterial cultures on solid and liquid media. We compared empiric treatment decisions with solid and liquid culture in terms of diagnostic yield and time to results, and assessed impact on patient management. RESULTS: Of 200 patients enrolled, 26 (13%) had culture-confirmed TB: 22 (85%) on solid culture alone, 2 (8%) on liquid culture alone, and 2 (8%) on both solid and liquid culture. Thirty-four patients received empiric anti-tuberculosis treatment, but only 10 (29%) were culture-positive. Median time to a positive result on solid culture was 92 days (interquartile range [IQR] 69-148) compared to 106 days (IQR 66-157) for liquid culture. No patients initiated treatment following a positive result on liquid culture. CONCLUSION: The introduction of mycobacterial culture did not influence care for patients undergoing evaluation for TB in Kampala, Uganda. Attention to contextual factors surrounding implementation is needed to ensure the effective introduction of new testing strategies in low-income countries.


Contexte : La mise en œuvre de nouvelles stratégies de diagnostic de la tuberculose (TB) dans les contextes de ressources limitées constitue un défi. Nous avons mesuré l'impact des cultures mycobactériennes en milieu solide et liquide sur les pratiques de traitement des patients ayant une évaluation de la TB à Kampala, Ouganda.Méthodes : Nous avons enrôlé des patients adultes consécutifs à frottis négatif, positifs pour le virus de l'immunodéficience humaine avec toux de ⩾2 semaines, de septembre 2009 à avril 2010. Les techniciens de laboratoire ont réalisé des cultures mycobactériennes en milieu solide et liquide. Nous avons comparé les décisions de traitement empirique aux cultures en milieu solide et liquide en termes de rendement diagnostique et de délai d'obtention des résultats et nous avons évalué l'impact sur la gestion des patients.Résultats : Des 200 patients enrôlés, 26 (13%) avaient une TB confirmée par culture, 22 (85%) par culture en milieu solide seule, 2 (8%) par culture en milieu liquide seul et 2 (8%) par culture à la fois en milieu solide et liquide. Trente-quatre patients ont reçu un traitement de TB empirique, mais seulement 10 (29%) ont eu une TB à culture positive. Le délai médian d'obtention d'un résultat de culture positive en milieu solide a été de 92 jours (IQR 69­148). Le délai médian d'obtention d'un résultat de culture positive en milieu liquide a été de 106 jours (IQR 66­157). Aucun patient n'a commencé un traitement à la suite d'un résultat de culture positive en milieu liquide.Conclusion : L'introduction de la culture mycobactérienne n'a pas influencé les soins aux patients bénéficiant d'une évaluation de TB à Kampala, Ouganda. Il est nécessaire d'être attentif aux facteurs contextuels entourant la mise en œuvre afin d'assurer une introduction effective de nouvelles stratégies de tests dans les pays à faible revenu.


Marco de referencia: La ejecución de nuevas estrategias de diagnóstico de la tuberculosis (TB) en los entornos con limitación de recursos es problemática. En el presente estudio se midió la repercusión del uso del cultivo de micobacterias en medio sólido o liquido sobre las prácticas de tratamiento de los pacientes en curso de investigación diagnóstica de la TB en Kampala, Uganda.Métodos: Se incluyeron de manera consecutiva en el estudio los pacientes adultos, seronegativos frente al virus de la inmunodeficiencia humana, que consultaban por tos de ⩾2 semanas de duración y presentaban baciloscopia negativa, de septiembre del 2009 a abril del 2010. Los auxiliares de laboratorio practicaron el cultivo de micobacterias en medio sólido y medio líquido. Se compararon las decisiones empíricas de tratamiento y los tipos de cultivo, con respecto al rendimiento diagnóstico y al lapso hasta obtener los resultados y se evaluó su repercusión en el manejo de los pacientes.Resultados: De los 200 pacientes que participaron en el estudio, 26 obtuvieron confirmación del diagnóstico de TB mediante el cultivo (13%), 22 de ellos con el cultivo en medio sólido únicamente (85%), dos con el cultivo en medio líquido exclusivamente y dos con ambos tipos de cultivo (8%). Treinta y cuatro pacientes recibieron tratamiento antituberculoso empírico, pero solo 10 de ellos obtuvieron un cultivo positivo (29%). La mediana del lapso hasta obtener el resultado del cultivo en medio sólido fue 92 días (IQR 69­148). La mediana de este lapso con los cultivos en medio líquido fue 106 días (IQR 66­157). Ningún paciente inició el tratamiento antituberculoso después de haber obtenido el resultado positivo del cultivo en medio líquido.Conclusión: La introducción del cultivo para micobacterias no tiene ninguna influencia en la atención que reciben los pacientes en quienes se investiga la TB en Kampala, Uganda. Es importante prestar atención a los factores contextuales que rodean la ejecución, a fin de lograr una introducción eficaz de las nuevas estrategias diagnósticas en los países con recursos limitados.

ABSTRACT

SETTING: An out-patient clinic in a country with high rates of tuberculosis-human immunodeficiency virus (TB-HIV) co-infection. DESIGN: Cross-sectional analytical study of 123 adults with chronic cough and no previous anti-tuberculosis treatment. Demographic, clinical, chest X-ray (CXR) and GeneXpert® MTB/RIF data were collected. Proportions of TB diagnoses using both tests were calculated and compared using an unpaired t-test. RESULTS: Sixty-six patients (53.7%) were female and 35 (28.5%) tested positive for HIV; 21 (17.1%) were Xpert-positive, while 51 (42.5%) had CXR suggestive of TB (P = 0.0018), of whom only 15 (29.4%) were Xpert-positive. CXR was suggestive of pulmonary TB in 15 (71.4%) of the 21 patients with a positive Xpert test. CONCLUSIONS: The majority of the sputum smear-negative patients did not have TB on single Xpert testing. CXR gave an overestimate of sputum smear-negative TB cases.

ABSTRACT

BACKGROUND: Cohorts describing cause specific mortality in HIV-infected patients initiating antiretroviral therapy (ART) operate on an outpatient basis. Hospitalized patients represent the spectrum and burden of severe morbidity and mortality in patients on ART. OBJECTIVE: To determine the causes and outcomes of hospitalization among adults receiving ART. METHODS: A prospective cohort study. We enrolled 201 participants (50% female) with median (IQR) age and CD4 count of 34 (28-40) years and 91(29-211) cells/uL respectively. RESULTS: The most frequent causes of hospitalization were tuberculosis (TB) (37, 18%), cryptococcal meningitis (22, 11%), zidovudine (AZT) - associated anemia (19, 10%), sepsis (10, 5%) and Kaposi's sarcoma (10, 5%). Forty two patients (21%) died: 10 (24%) had TB, 8 (19%) had cryptococcal meningitis and 5 (12%) had sepsis, 9 (21%) had undiagnosed neurological syndromes while 10 (24%) had other illnesses. Predictors of death included low Karnofsky performance score of < 40 (OR, 21.1; CI 1.43- 31.6) and age >34 years (OR, 7.65; CI 1.09- 53.8). CONCLUSIONS: Opportunistic infections, malignancy and AZT-associated anemia contributed to most hospitalizations and mortality. It is important to intensify prevention, screening, and treatment for these opportunistic diseases and early ART initiation in HIV-infected patients. Tenofovir-based regimens, unless contraindicated should be scaled up to replace AZT-based regimens as first line ART drugs.

ABSTRACT

We evaluated the accuracy of heat-denatured, amplification-boosted ultrasensitive p24 assay (Up24) compared with reverse transcriptase polymerase chain reaction (RT-PCR). We tested 394 samples from Ugandans infected with HIV-1 non-B subtypes. We compared Up24 levels (HIV-1 p24 Core Profile enzyme-linked immunosorbent assay (ELISA), NEN Life Science Products) to RNA viral loads (Amplicor HIV-1 Monitor 1.5, Roche) by linear regression, and calculated sensitivity, specificity, positive and negative predictive values. Median viral load was 4.9 log10 copies/mL (interquartile range [IQR], 2.6-5.5); 114 samples (29%) were undetectable (<400 copies/mL). Sensitivity of the Up24 assay to detect viral load ≥400 copies/mL was 69%, specificity was 67%, and positive and negative predictive values were 84% and 47%, respectively. Sensitivity of Up24 was 90%, 80%, 68%, 62% and 45% to detect viral loads of >500,000, 250,000-500,000, 100,000-250,000, 50,000-100,000 and 400-50,000 copies/mL, respectively. In conclusion, when compared with RT-PCR for patients infected with non-B subtypes, the Up24 demonstrated limited sensitivity especially at low viral loads. Moreover, the Up24 was positive in 33% of samples deemed undetectable by RT-PCR, which may limit the use of the Up24 to detect viral suppression.

ABSTRACT

SETTING: Mulago Hospital, Uganda. OBJECTIVE: To evaluate the burden of TB-HIV (tuberculosis-human immunodeficiency virus) co-infections and their predictors in an urban hospital-based HIV programme. DESIGN: Prospective observational study. METHODS: Clinicians screened all patients with HIV/AIDS (acquired immune-deficiency syndrome) for previous and current TB treatment at enrolment and throughout follow-up. RESULTS: Of 10,924 patients enrolled between August 2005 and February 2009, co-prevalent TB was 157/10,924 (1.4%), which included 88/157 (56%) with TB confirmed at enrolment and 65/157 (41%) with TB diagnoses established during follow-up in whom symptoms were present at enrolment. Male sex (adjusted odds ratio [aOR] 2.3, 95%CI 1.6-3.2) and body mass index (BMI) ≤ 20 kg/m(2) (aOR 3.8, 95%CI 2.5-5.4) were associated with co-prevalent TB. Overall, 749/10,767 (7%) were diagnosed with incident TB at a higher rate among antiretroviral treatment (ART) patients (8/100 patient years of observation [PYO]) than non-ART patients (5/100 PYO, log rank P < 0.001). Female sex (adjusted hazard ratio [aHR] 1.4, 95%CI 1.2-1.7) and baseline BMI ≤ 20 (aHR 1.9, 95%CI 1.6-2.2) predicted incident TB. CONCLUSION: Routine TB screening in the HIV/AIDS care programme identified a significant number of TB-HIV co-infections among patients with and without ART, and is therefore a potential strategy to improve HIV treatment outcomes in resource-limited settings.

ABSTRACT

Liver enzyme elevations among patients on antiretroviral therapy (ART) were determined by prospectively evaluating aspartate aminotransferase (AST) data in a cohort of patients in Kampala over 36 months. A proportion of patients had hepatitis B virus (HBV) status determined. Hepatotoxicity was graded I to IV according to the AIDS Clinical Trial Group criteria. Of 546 patients, 377 (69%) were women; overall median baseline CD4+ T-cell was 97/µL (interquartile range [IQR] 20-164). Hepatitis B surface antigen (HBsAg) was detected in 42 (9%) of 470 persons. ART included lamivudine, with either nevirapine and d4T (74%) or efavirenz and AZT (26%). Median (IQR) AST level at baseline was 35 (27, 53 IU/L). Over 36 months, only eight patients had grade III AST elevation. Neither HBsAg nor ART regimen influenced AST levels. Male gender and CD4+ change from baseline were correlated with AST elevation. Patients with HIV/HBV co-infection were not at an increased risk of AST elevation, which occurred uncommonly in this setting.

ABSTRACT

BACKGROUND: Severe malaria is responsible for the high load of malaria mortality. It is not clearly understood why some malaria episodes progress to severe malaria. OBJECTIVE: To determine factors associated with severe malaria in children aged 6 months to 5 years living in Kampala. METHODS: Over a 6-month period, 100 children with severe malaria were matched by age and place of residence with 100 children with non-severe malaria. We collected health care information from care takers. RESULTS: Mean duration of illness before getting antimalarial treatment was shorter for controls than cases (8 hours vs. 20 hours, p 0.015). Children with severe malaria were less likely to have been treated with sulphadoxine-pyrimethamine in the preceding 2 weeks (OR 0.2, 95% CI 0.04-0.85, p 0.016). Odds of severe malaria were higher in those who reported lack of protective measures (mosquito coils (OR = 20.63, 95% CI 1.5-283.3, p=0.02 and insecticide sprays OR 10.93, 95% CI 1.13-105.64, p=0.03), although few reported their use. CONCLUSIONS: Early anti-malarial treatment and use of barriers against mosquitoes prevent severe malaria in children. There is need to increase the use of barriers against mosquito bites and to scale up prompt treatment and community-based interventions to reduce the incidence of severe malaria in children.

ABSTRACT

This study assessed the feasibility of a group-based couples intervention to increase condom use in HIV serodiscordant couples in three countries (India, Thailand and Uganda). The intervention focused on communication, problem solving, and negotiation skills. Forty-three couples enrolled in the intervention (15 in India, 14 in Thailand, and 14 in Uganda) and 40 couples completed all study activities. Participants were interviewed at baseline and at one and three months post- intervention. The intervention consisted of two same sex sessions and two couples sessions with 'homework' to practice skills between sessions. The same intervention modules were used at each site, tailored for local appropriateness. Participants at each site were enthusiastic about the intervention, citing information about HIV serodiscordancy and the opportunity to meet couples 'like us' as important features. Participants reported increased comfort discussing sex and condoms with their partner, although some participants remain concerned about situations when condoms might not be used (e.g. when drunk). At three-month follow up 90% of the participants reported having been able to use the skills from the intervention with their partner. Our results highlight the feasibility of this couples group-based intervention and the need for ongoing support for discordant couples.

ABSTRACT

Background: Malaria and HIV-1 infection cause significant morbidity and mortality in sub-Saharan Africa. HIV-1 increases risk for malaria with the risk increasing as immunity declines.The effect of HIV-1 infection on antimalarial treatment outcome is still inconclusive. Objective: To compare antimalarial treatment outcome among HIV-1 positive and negative patients with acute uncomplicated falciparum malaria treated with chloroquine plus sulfadoxine-pyrimethamine (CQ+SP). Methods: Ninety eight HIV-1 positive patients aged 18 months or older with acute uncomplicated falciparum malaria were treated with CQ+SP and followed for 28 days to monitor outcome.Treatment outcome of HIV-1 positive patients was compared to that of 193 HIV-1 negative historical controls.The primary study outcome for both groups was treatment failure. Results: HIV-1 positive patients older than 5 years of age were less likely to have treatment failure compared to HIV-1 negative patients in the same age group (RR 0.59 95CI 0.4- 0.8; p a 0.001) and HIV-1 positive patients on routine cotrimoxazole prophylaxis were less likely to have treatment failure following CQ+SP treatment compared to HIV negative patients (RR 0.6 95CI 0.43-0.92; p = 0.006).There was no difference in treatment outcome according to HIV-1 status for children younger than 5 years of age. Conclusions: Adherence to cotrimo-xazole prophylaxis should be reinforced in HIV positive patients and it should be reassessed if these patients present with acute episodes of malaria

ABSTRACT

Background: Despite global effort to scale up access to antiretroviral therapy (ART); many people in need of HIV/AIDS care in Uganda have not been reached. HIV testing and ART are not widely offered as routine medical services and data on HIV/AIDS in emergency settings in Sub-Saharan Africa is limited.We determined the HIV prevalence and eligibility for ART in a medical emergency unit at Mulago hospital. Methods: In a cross-sectional study; we interviewed 223 patients who were systematically selected from the patients'register from October through December 2004. HIV testing was offered routinely and results were delivered within 30 minutes.We evaluated HIV infected patients for WHO clinical stage of disease and referred them for HIV/AIDS care. Results: Out of 223 patients; 111 (50) had HIV infection of whom 78 (70) had WHO clinical stage 3 and 4 of disease thereby requiring ART. Overall; 84 out of 111 (76) HIV positive patients had not received any specific HIV/AIDS care. Conclusion: The burden of HIV infection in the medical emergency unit is high and majority of the patients who required ART had no prior HIV/AIDS care.We recommend scale up of HIV/AIDS care in acute care settings in order to increase access to ART

ABSTRACT

Background: Presumptive treatment of malaria in febrile children is widely advocated in Africa. This may occur in the absence of diagnostic testing or even when diagnostic testing is performed but fails to detect malaria parasites. Such over-treatment of malaria has been tolerated in the era of inexpensive and safe monotherapy. However; with the introduction of new artemisinin-based combination therapy (ACT); presumptive treatment becomes economically and clinically less acceptable. Methods: The risks and benefits of only treating children with microscopy confirmed malaria using a prospective cohort design were investigated. A representative sample of 601 children between one and 10 years of age were recruited from a census population in Kampala; Uganda and were followed for all of their health care needs in a study clinic. Standard microscopy was performed each time a child presented with a new episode of fever and antimalarial therapy given only if the blood smear was positive. Results: Of 5;895 visits for new medical problems 40were for febrile illnesses. Of the 2;359 episodes of new febrile illnesses; blood smears were initially reported as negative in 1;608 (68) and no antimalarial therapy was given. Six of these initially negative smears were reported to be positive following quality control reading of all blood smears: four of these patients were subsequently diagnosed with uncomplicated malaria and two cleared their parasites without antimalarial treatment. Of the 1;602 new febrile illnesses in which the final blood smear reading was classified as negative; only 13 episodes (0.8) were diagnosed with malaria in the subsequent 7 days. All 13 of these episodes of malaria were uncomplicated and were successfully treated.Conclusions: In this urban setting; malaria was responsible for only 32of febrile episodes. Withholding antimalarial therapy in febrile children with negative blood smears was safe and saved over 1;600 antimalarial treatments in 601 children over an 18-month period. In the era of expensive ACT; directing resources towards improving diagnostic and treatment practices may provide a cost-effective measure for promoting rational use of antimalarial therapy
