Association of HIV/AIDS Clinician Warm Line Utilization with Diagnosis and Management of Antiretroviral Treatment Failure in Mozambique: A Retrospective Analysis of Program Data.

In accordance with global HIV/AIDS goals, Mozambique is attempting to improve management of antiretroviral treatment failure (TF). We sought to determine whether the utilization of a national HIV/AIDS clinician telephone consultation service increased recognition and reporting of TF. In a retrospective analysis of routinely collected program data from telephone consultation logs and Mozambique's national registry of second-line antiretroviral requests, we used linear mixed methods to describe the association between TF-related telephone consultations and submission of second-line requests, which required documentation of the TF diagnosis. The unit of analysis was the health facility. Available data included 1417 consultations (390 [27.5%] TF related) and 2662 second-line requests from 1011 health units (2015-2016 data). In multivariable analyses, each TF-related consultation was associated with an increase of 0.61 (95% confidence interval 0.15 to 1.06) second-line requests. In this setting, TF-related telephone consultation was positively and significantly associated with diagnosis and reporting of antiretroviral TF.

Practical Management of HIV-Associated Anemia in Resource-Limited Settings: Prospective Observational Evaluation of a New Mozambican Guideline.

Mozambique's updated guideline for management of HIV-associated anemia prompts clinicians to consider opportunistic conditions, adverse drug reactions, and untreated immunosuppression in addition to iron deficiency, intestinal helminthes, and malaria. We prospectively evaluated this guideline in rural Zambézia Province. Likely cause(s) of anemia were determined through prespecified history, physical examination, and laboratory testing. Diagnoses were "etiologic" if laboratory confirmed (sputum microscopy, blood culture, Plasmodium falciparum malaria rapid test) or "syndromic" if not. To assess hemoglobin response, we used serial point-of-care measurements. We studied 324 ambulatory, anemic (hemoglobin <10 g/dl) HIV-infected adults. Study clinicians treated nearly all [315 (97.2%)] for suspected iron deficiency and/or helminthes; 56 (17.3%) had laboratory-confirmed malaria. Other assigned diagnoses included tuberculosis [30 (9.3%)], adverse drug reactions [26 (8.0%)], and bacteremia [13 (4.1%)]. Etiologic diagnosis was achieved in 79 (24.4%). Of 169 (52.2%) subjects who improved (hemoglobin increase of ≥1 g/dl without indications for hospitalization), only 65 (38.5%) received conventional management (iron supplementation, deworming, and/or antimalarials) alone. Thirty (9.3%) died and/or were hospitalized, and 125 (38.6%) were lost to follow-up. Multivariable linear and logistic regression models described better hemoglobin responses and/or outcomes in subjects with higher CD4(+) T-lymphocyte counts, pre-enrollment antiretroviral therapy and/or co-trimoxazole prophylaxis, discontinuation of zidovudine for suspected adverse reaction, and smear-positive tuberculosis. Adverse outcomes were associated with fever, low body mass index, bacteremia, esophageal candidiasis, and low or missing CD4(+) T cell counts. In this severely resource-limited setting, successful anemia management often required interventions other than conventional presumptive treatment, thus supporting Mozambique's guideline revision.

Identification of Invasive Salmonella Enterica Serovar Typhimurium ST313 in Ambulatory HIV-Infected Adults in Mozambique.

INTRODUCTION: Despite evidence describing the burden of invasive non-typhoidal salmonella (iNTS) disease in sub-Saharan Africa, iNTS is not recognized as a priority within global health policy institutions. Recently, Salmonella enterica serovar Typhimurium, sequence type (ST) 313, has been identified as the predominant cause of iNTS disease in multiple sub-Saharan African countries. MATERIALS AND METHODS: We conducted multilocus sequence typing (MLST) to determine the prevalence of the ST313 genotype in a sample of blood isolates from ambulatory HIV-infected Mozambican adults with iNTS disease. RESULTS: Of the 29 samples of NTS obtained and analyzed by MLST, all (29/29) were assigned the ST313 sequence type based on the set of allele types derived from each of the seven loci. For quality control, five randomly selected strains taken from the original cultures were confirmed as ST313, and the positive control strain SL3261 (taken from the original culture) was categorized as S. Typhimurium ST19. CONCLUSION: S. Typhimurium ST313 is an important example of a widely distributed pathogen that lacks a coordinated strategy for control. The highly vulnerable populations at risk for ST313 infection in Mozambique, and within the region, would benefit greatly from the development of new policy and on-the-ground capacity to support increased surveillance, prevention, and treatment initiatives.

Management of fever in ambulatory HIV-infected adults in resource-limited settings: prospective observational evaluation of a new Mozambican guideline.

A new Mozambican guideline for management of fever in HIV-infected adults requires malaria testing and systematic consideration of specific alternative diagnoses (eg, tuberculosis and bacterial infections) in addition to malaria. We conducted a prospective observational study of the guideline's performance. Of 258 HIV-infected subjects with axillary temperature ≥37.5° C or history of fever, 76.0% improved, 13.6% died or were hospitalized, and 10.5% were lost to follow-up. In multivariate analyses, factors associated with adverse outcomes were bacterial blood stream infection, syndromically diagnosed tuberculosis, lower CD4 T-lymphocyte count, no antiretroviral therapy, lower body mass index, lower hemoglobin, and nonprescription of antibiotics.

Bacteremia as a cause of fever in ambulatory, HIV-infected Mozambican adults: results and policy implications from a prospective observational study.

Fever is typically treated empirically in rural Mozambique. We examined the distribution and antimicrobial susceptibility patterns of bacterial pathogens isolated from blood-culture specimens, and clinical characteristics of ambulatory HIV-infected febrile patients with and without bacteremia. This analysis was nested within a larger prospective observational study to evaluate the performance of new Mozambican guidelines for fever and anemia in HIV-infected adults (clinical trial registration NCT01681914, www.clinicaltrials.gov); the guidelines were designed to be used by non-physician clinicians who attended ambulatory HIV-infected patients in very resource-constrained peripheral health units. In 2012 (April-September), we recruited 258 HIV-infected adults with documented fever or history of recent fever in three sites within Zambézia Province, Mozambique. Although febrile patients were routinely tested for malaria, blood culture capacity was unavailable in Zambézia prior to study initiation. We confirmed bacteremia in 39 (15.1%) of 258 patients. The predominant organisms were non-typhoid Salmonella, nearly all resistant to multiple first-line antibiotics (ampicillin, chloramphenicol, and trimethoprim-sulfamethoxazole). Features most associated with bacteremia included higher temperature, lower CD4+ T-lymphocyte count, lower hemoglobin, and headache. Introduction of blood cultures allowed us to: 1) confirm bacteremia in a substantial proportion of patients; 2) tailor specific antimicrobial therapy for confirmed bacteremia based on known susceptibilities; 3) make informed choices of presumptive antibiotics for patients with suspected bacteremia; and 4) construct a preliminary clinical profile to help clinicians determine who would most likely benefit from presumptive bacteremia treatment. Our findings demonstrate that in resource-limited settings, there is urgent need to expand local microbiologic capacity to better identify and treat cases of bacteremia in HIV-infected and other patients, and to support surveillance. Data on the prevalence and susceptibility patterns of important pathogens can guide national formulary and prescribing practices.

Determinants of use of insecticide treated nets for the prevention of malaria in pregnancy: Jinja, Uganda.

BACKGROUND: One established means of preventing the adverse consequences of malaria during pregnancy is sleeping under an insecticide treated net (ITN) throughout pregnancy. Despite increased access to this intervention over time, consistent ITN use during pregnancy remains relatively uncommon in sub-Saharan Africa. METHODOLOGY/PRINCIPAL FINDINGS: We sought to identify determinants of ITN use during pregnancy. Utilizing a population-based random sample, we interviewed 500 women living in Jinja, Uganda, who had been pregnant in the past year. ITN ownership at the start of pregnancy was reported by 359 women (72%) and 28 women (20%) acquired an ITN after the first trimester of pregnancy. Among 387 ITN owners, 73% reported either always sleeping under the ITN during all trimesters of pregnancy, or after acquiring their net. Owning more than 1 net was slightly associated with always sleeping under an ITN during pregnancy (RR: 1.13; 95% CI: 1.00, 1.28). Women who always slept under an ITN during pregnancy were more likely to be influenced by an advertisement on the radio/poster than being given an ITN free of charge (RR: 1.48; 95% CI: 1.24, 1.76). No differences were found between other socio-demographic factors, pregnancy history, ANC use or socio-cultural factors. CONCLUSIONS/SIGNIFICANCE: While self-reported ITN ownership and use was common throughout pregnancy, we were unable to pinpoint why a sizable fraction of Ugandan women did not always adhere to recommendations for use of an ITN during pregnancy. More data are needed on the capacity of individual households to support the installation of ITNs which may provide insight into interventions targeted at improving the convenience and adherence of daily ITN use.

Patterns of anti-malarial drug treatment among pregnant women in Uganda.

BACKGROUND: Prompt use of an effective anti-malarial drug is essential for controlling malaria and its adverse effects in pregnancy. The World Health Organization recommends an artemisinin-based combination therapy as the first-line treatment of uncomplicated malaria in the second and third trimesters of pregnancy. The study objective was to determine the degree to which presumed episodes of uncomplicated symptomatic malaria in pregnancy were treated with a recommended anti-malarial regimen in a region of Uganda. METHODS: Utilizing a population-based random sample, we interviewed women living in Jinja, Uganda who had been pregnant in the past year. RESULTS: Self-reported malaria during the index pregnancy was reported among 67% (n = 334) of the 500 participants. Among the 637 self-reported episodes of malaria, an anti-malarial drug was used for treatment in 85% of the episodes. Use of a currently recommended treatment in the first trimester was uncommon (5.6%). A contraindicated anti-malarial drug (sulphadoxine-pyrimethamine and/or artemether-lumefantrine) was involved in 70% of first trimester episodes. Recommended anti-malarials were used according to the guidelines in only 30.1% of all second and third trimester episodes. CONCLUSIONS: Self-reported malaria was extremely common in this population and adherence to treatment guidelines for the management of malaria in pregnancy was poor. Use of artemether-lumefantrine combined with non-recommended anti-malarials was common practice. Overuse of anti-malarial drugs, especially ones that are no longer recommended, undermines malaria control efforts by fueling the spread of drug resistance and delaying appropriate treatment of non-malarial febrile illnesses. Improved diagnostic capacity is essential to ultimately improving the management of malaria-like symptoms during pregnancy and appropriate use of currently available anti-malarials.

Predictors of survival after a diagnosis of non-Hodgkin lymphoma in a resource-limited setting: a retrospective study on the impact of HIV infection and its treatment.

OBJECTIVE: We examined factors associated with survival among patients with newly diagnosed non-Hodgkin lymphoma (NHL) in Uganda. METHODS: Information was abstracted from medical records for all NHL patients >13 years of age at the Uganda Cancer Institute between January 2004 and August 2008. Cox proportional hazard models were used to identify predictors of NHL survival. RESULTS: One hundred sixty patients with NHL were identified; 51 (31.9%) were known to be HIV positive. Overall, 154 patients had records sufficient for further analysis. The median person-time observed was 104 days (interquartile range 26-222). Median survival after presentation among those whose mortality status was confirmed was 61 days (interquartile range 25-203). HIV-positive patients receiving antiretroviral therapy had survival rates approximating those of HIV-negative persons, but the adjusted hazard of death was significantly elevated among HIV-positive patients not receiving antiretroviral therapy [adjusted hazard ratio (HR) 8.99, P < 0.001] compared with HIV-negative patients. Both B-symptoms (HR 2.08, P = 0.05) and female gender (HR 1.72, P = 0.05) were associated with higher mortality. CONCLUSIONS: In Uganda, overall survival of NHL patients is poor, and predictors of survival differed from those described in resource-rich regions. HIV is a common comorbidity to NHL, and its lack of treatment was among the strongest predictors of mortality. Strategies are needed for optimal management of HIV-infected individuals with cancer in resource-limited settings.

Determinants of use of intermittent preventive treatment of malaria in pregnancy: Jinja, Uganda.

BACKGROUND: Maternal malaria is associated with serious adverse pregnancy outcomes. One recommended means of preventing malaria during pregnancy is intermittent preventive therapy (IPTp) with sulfadoxine/pyrimethamine (SP). We sought to identify determinants of preventive use of SP during pregnancy among recently pregnant women in Uganda. Additionally, we characterized the timing of and indications for the administration of SP at antenatal care (ANC) visits and missed opportunities for SP administration. METHODOLOGY/PRINCIPAL FINDINGS: Utilizing a population-based random sample, we interviewed 500 women living in Jinja, Uganda who had been pregnant in the past year. Thirty-eight percent (192/500) of women received SP for the treatment of malaria and were excluded from the analysis of IPTp-SP. Of the remaining women, 275 (89.3%) reported at least two ANC visits after the first trimester and had an opportunity to receive IPTp-SP according to the Ugandan guidelines, but only 86 (31.3%) of these women received a full two-dose course of IPTp. The remaining 189 (68.7%) women missed one or more doses of IPTp-SP. Among the 168 women that were offered IPTp, 164 (97.6%) of them took the dose of SP. CONCLUSIONS/SIGNIFICANCE: Use of IPTp in Uganda was found to be far below target levels. Our results suggest that women will take SP for IPTp if it is offered during an ANC visit. Missed opportunities to administer IPTp-SP during ANC were common in our study, suggesting provider-level improvements are needed.

Task shifting in Mozambique: cross-sectional evaluation of non-physician clinicians' performance in HIV/AIDS care.

BACKGROUND: Many resource-constrained countries now train non-physician clinicians in HIV/AIDS care, a strategy known as 'task-shifting.' There is as yet no evidence-based international standard for training these cadres. In 2007, the Mozambican Ministry of Health (MOH) conducted a nationwide evaluation of the quality of care delivered by non-physician clinicians (técnicos de medicina, or TMs), after a two-week in-service training course emphasizing antiretroviral therapy (ART). METHODS: Forty-four randomly selected TMs were directly observed by expert clinicians as they cared for HIV-infected patients in their usual worksites. Observed clinical performance was compared to national norms as taught in the course. RESULTS: In 127 directly observed patient encounters, TMs assigned the correct WHO clinical stage in 37.6%, and correctly managed co-trimoxazole prophylaxis in 71.6% and ART in 75.5% (adjusted estimates). Correct management of all 5 main aspects of patient care (staging, co-trimoxazole, ART, opportunistic infections, and adverse drug reactions) was observed in 10.6% of encounters.The observed clinical errors were heterogeneous. Common errors included assignment of clinical stage before completing the relevant patient evaluation, and initiation or continuation of co-trimoxazole or ART without indications or when contraindicated. CONCLUSIONS: In Mozambique, the in-service ART training was suspended. MOH subsequently revised the TMs' scope of work in HIV/AIDS care, defined new clinical guidelines, and initiated a nationwide re-training and clinical mentoring program for these health professionals. Further research is required to define clinically effective methods of health-worker training to support HIV/AIDS care in Mozambique and similarly resource-constrained environments.

Clinical staging of HIV-related illness in Mozambique: performance of nonphysician clinicians based on direct observation of clinical care and implications for health worker training.

INTRODUCTION: In Mozambique, clinical staging may be the primary determinant of HIV/AIDS treatment decisions, and the task of staging commonly falls to nonphysician clinicians (técnicos de medicina). Two years after the first Mozambican técnicos were trained in HIV/AIDS care, the quality of their performance in clinical staging was unknown. METHODS: Expert clinicians observed 127 clinical encounters conducted by a randomly selected national sample of 44 técnicos and compared observed clinical staging decisions to World Health Organization and Mozambican national norms. They also reviewed relevant Mozambican in-service training curricula in HIV/AIDS care. RESULTS: Observers agreed with fewer than half (44.1%) of the técnicos' stage-defining diagnoses. Misclassification or misdiagnosis of 3 complaints (weight loss, fever, and diarrhea) accounted for the majority of the observed errors. Review of health worker curricula determined that observed staging errors reflected content errors and omissions in the técnicos' in-service HIV/AIDS training and constraints in local laboratory and imaging capacity. DISCUSSION: In response to these findings, the Mozambican Ministry of Health has revised the técnicos' scope of work and has developed new guidelines, curriculum materials, and training strategies to improve the quality of clinical staging and opportunistic infection diagnosis in Mozambique.

Armed conflict and poverty in Central America: the convergence of epidemiology and human rights advocacy.

Several armed conflicts took place in Central America during the last 3 decades of the 20th century. In this commentary, we discuss (1) studies describing the interrelationships among health, violence, and poverty during and after these conflicts and (2) some important lessons learned from these studies. We hope that those lessons help epidemiologists and others who must confront, and describe, similar situations elsewhere.

Intermittent preventive treatment of malaria during pregnancy in central Mozambique.

PROBLEM: New WHO strategies for control of malaria in pregnancy (MiP) recommend intermittent preventive treatment (IPTp), bednet use and improved case management. APPROACH: A pilot MiP programme in Mozambique was designed to determine requirements for scale-up. LOCAL SETTING: The Ministry of Health worked with a nongovernmental organization and an academic institution to establish and monitor a pilot programme in two impoverished malaria-endemic districts. RELEVANT CHANGES: Implementing the pilot programme required provision of additional sulfadoxine-pyrimethamine (SP), materials for directly observed SP administration, bednets and a modified antenatal card. National-level formulary restrictions on SP needed to be waived. The original protocol required modification because imprecision in estimation of gestational age led to missed SP doses. Multiple incompatibilities with other health initiatives (including programmes for control of syphilis, anaemia and HIV) were discovered and overcome. Key outputs and impacts were measured; 92.5% of 7911 women received at least 1 dose of SP, with the mean number of SP doses received being 2.2. At the second antenatal visit, 13.5% of women used bednets. In subgroups (1167 for laboratory analyses; 2600 births), SP use was significantly associated with higher haemoglobin levels (10.9 g/dL if 3 doses, 10.3 if none), less malaria parasitaemia (prevalence 7.5% if 3 doses, 39.3% if none), and fewer low-birth-weight infants (7.3% if 3 doses, 12.5% if none). LESSONS LEARNED: National-level scale-up will require attention to staffing, supplies, bednet availability, drug policy, gestational-age estimation and harmonization of vertical initiatives.

Challenges in the prevention, diagnosis, and treatment of malaria in human immunodeficiency virus infected adults in sub-Saharan Africa.

BACKGROUND: Many countries in sub-Saharan Africa currently report high prevalences of both human immunodeficiency virus (HIV) and Plasmodium falciparum malaria. The likelihood of HIV-malaria coinfection may affect clinical management of patients. The extent to which standard clinical guidelines address HIV-malaria coinfection is unclear. METHODS: We reviewed standard World Health Organization and other guidelines for diagnosis and treatment of malaria and/or HIV-related illness. We also searched PubMed (1990 to present) for literature on HIV-malaria interactions and treatment of coinfection. We restricted our review to the situation of the nonpregnant HIV-infected adult. RESULTS: We found only 6 articles describing the clinical presentation of HIV-malaria coinfection in adults. We also identified 10 clinical or laboratory syndromes that are shared by malaria and AIDS-related conditions and that might provoke diagnostic confusion. We identified 12 antimalarial medications whose coadministration with antiretrovirals is known or suspected to result in drug-drug interactions or overlapping toxicities. CONCLUSIONS: Substantial overlap in the clinical and laboratory characteristics of malaria and HIV-related syndromes generates potential difficulties in AIDS staging and in diagnosis and management of patients at risk for coinfection. Significant drug-drug interactions and overlapping drug toxicity profiles further complicate concurrent management of malaria and HIV. Standard clinical guidelines do not reflect the full complexity of the interactions and overlaps between the 2 infections. Clinicians who manage HIV-infected patients in malaria-affected regions should systematically consider malaria when evaluating patients with a broad spectrum of symptoms. Further research is urgently needed to define best practices for prevention, diagnosis, and management of HIV-malaria coinfection in this region.

Prevalence and predictors of maternal peripheral malaria parasitemia in central Mozambique.

Malaria infection during pregnancy (MiP) is heterogeneously distributed even in malaria-endemic countries. Program planners require data to facilitate identification of highest-priority populations for MiP control. Using data from two cross-sectional studies of 5,528 pregnant women in 8 neighboring sites in Mozambique, we described factors associated with maternal peripheral parasitemia by using logistic regression. Principal multivariate predictors of maternal peripheral parasitemia were gravidity (odds ratio [OR] = 2.29, 95% confidence interval [CI] = 1.60-3.26 for primigravidae and OR = 1.61, 95% CI = 1.29-2.01 for secundigravidae compared with gravidity > or = 3); age (OR = 0.96 per year, 95% CI = 0.94-0.99); study site (OR = 1.45, 95% CI = 1.34-1.56 to 5.32, 95% CI = 4.92-5.75) for comparison with the reference site; and no maternal education (OR = 1.38, 95% CI = 1.15-1.66) compared with any education. Other predictors (in subgroups) were bed net use (OR = 0.49, 95% CI = 0.48-0.50); preventive sulfadoxine-pyrimethamine doses (OR = 0.25, 95% CI = 0.24-0.25); and infection with human immunodeficiency virus (HIV) (OR = 1.49, 95% CI = 1.11-2.00). Programmatic priorities should respond to heterogeneous distribution of multiple risk factors, including prevalence of malaria and infection with HIV, and maternal socioeconomic status.

Lessons learned from bednet distribution in Central Mozambique.

INTRODUCTION: Malaria is an important cause of mortality and morbidity in sub-Saharan Africa. Use of insecticide-treated bednets (ITNs) is an important preventive intervention. Selection of the best mechanisms for distribution and promotion of ITNs to vulnerable populations is an important strategic issue. METHODS: Commercial shopkeepers and groups of community leaders were trained to promote and sell ITNs in 19 sites in central Mozambique between 2000 and 2004. Pregnant women and children under 5 years of age comprised the target population. Sales records, household survey results and project experiences were examined to derive 'lessons learned'. PRIMARY OUTCOME: An end-of-project household survey revealed that 40.8% of households owned one or more bednets, but only 19.6% of households owned a net that had been re-treated with insecticide within the preceding 6 months. Higher levels of bednet (treated or untreated) coverage (over 50%) were achieved in urban or peri-urban sites than in rural sites (as low as 15%). Bednet ownership was significantly associated with higher socio-economic status (odds ratios for association with bednet ownership: 5.6 for highest educational level compared with no education, 0.4 for dirt floor compared with cement or other finished flooring, 2.1 for automobile ownership compared with transportation on foot), but was negatively associated with the presence of young children in the household (odds ratio 0.5). Primary output: 23 000 ITNs were sold during the course of the project. Process lessons: Nearly all of the community leader sites failed and were replaced by shopkeepers or Ministry of Health personnel. Sales were most brisk in more prosperous urban and peri-urban sites (up to 147 nets/month) but were significantly slower in poorer, rural sites (as low as three nets/month). Remote rural sites with slow sales were more expensive to serve. Logistical difficulties were related to tariffs, transport, management of cash, warehousing and organization of re-treatment campaigns. CONCLUSIONS: This project failed to achieve adequate or equitable levels of ITN coverage in a timely manner in the programme sites. However, its findings helped support a subsequent Mozambican decision to conduct targeted distribution of long-lasting nets to the neediest populations in the provinces where the project was conducted.

Comparison of the diagnostic accuracy of a rapid immunochromatographic test and the rapid plasma reagin test for antenatal syphilis screening in Mozambique.

OBJECTIVE: Programmes to control syphilis in developing countries are hampered by a lack of laboratory services, delayed diagnosis, and doubts about current screening methods. We aimed to compare the diagnostic accuracy of an immunochromatographic strip (ICS) test and the rapid plasma reagin (RPR) test with the combined gold standard (RPR, Treponema pallidum haemagglutination assay and direct immunofluorescence stain done at a reference laboratory) for the detection of syphilis in pregnancy. METHODS: We included test results from 4789 women attending their first antenatal visit at one of six health facilities in Sofala Province, central Mozambique. We compared diagnostic accuracy (sensitivity, specificity, and positive and negative predictive values) of ICS and RPR done at the health facilities and ICS performed at the reference laboratory. We also made subgroup comparisons by human immunodeficiency virus (HIV) and malaria status. FINDINGS: For active syphilis, the sensitivity of the ICS was 95.3% at the reference laboratory, and 84.1% at the health facility. The sensitivity of the RPR at the health facility was 70.7%. Specificity and positive and negative predictive values showed a similar pattern. The ICS outperformed RPR in all comparisons (P<0.001). CONCLUSION: The diagnostic accuracy of the ICS compared favourably with that of the gold standard. The use of the ICS in Mozambique and similar settings may improve the diagnosis of syphilis in health facilities, both with and without laboratories.
