Investigating the etiology of acute febrile illness: a prospective clinic-based study in Uganda.

Background: Historically, malaria has been the predominant cause of acute febrile illness (AFI) in sub-Saharan Africa. However, during the last two decades, malaria incidence has declined due to concerted public health control efforts, including the widespread use of rapid diagnostic tests leading to increased recognition of non-malarial AFI etiologies. Our understanding of non-malarial AFI is limited due to lack of laboratory diagnostic capacity.

Infectious Diseases Institute at Makerere University College of Health Sciences: a case study of a sustainable capacity building model for health care, research and training.

Unlabelled: The Infectious Diseases Institute (IDI), established in 2001, was the first autonomous institution of Makerere University set up as an example of what self-governing institutes can do in transforming the academic environment to become a rapidly progressive University addressing the needs of society This paper describes the success factors and lessons learned in development of sustainable centers of excellence to prepare academic institutions to respond appropriately to current and future challenges to global health. Key success factors included a) strong collaboration by local and international experts to combat the HIV pandemic, along with b) seed funding from Pfizer Inc., c) longstanding collaboration with Accordia Global Health Foundation to create and sustain institutional strengthening programs, d) development of a critical mass of multi-disciplinary research leaders and managers of the center, and e) a series of strong directors who built strong governance structures to execute the vision of the institute, with subsequent transition to local leadership.

HIV drug resistance among adults initiating antiretroviral therapy in Uganda.

Background: WHO revised their HIV drug resistance (HIVDR) monitoring strategy in 2014, enabling countries to generate nationally representative HIVDR prevalence estimates from surveys conducted using this methodology. In 2016, we adopted this strategy in Uganda and conducted an HIVDR survey among adults initiating or reinitiating ART.

Methods: A cross-sectional survey of adults aged ≥18 years initiating or reinitiating ART was conducted at 23 sites using a two-stage cluster design sampling method.

Population-based monitoring of HIV drug resistance early warning indicators in Uganda: A nationally representative survey following revised WHO recommendations.

Introduction: With the scale-up of antiretroviral therapy (ART) there is a need to monitor programme performance to maximize ART efficacy and to prevent emergence of HIV drug resistance (HIVDR). In keeping with the elements of the World Health Organisation (WHO) guidance we carried out a nationally representative assessment of early warning indicators (EWI) at 304 randomly selected ART service outlets in Uganda.

Methods: Retrospective patient data was extracted for the six EWIs for HIVDR including; on-time antiretroviral (ARV) drug pick-up, patient retention on ART at 12 months, ART dispensing practices, ARV drug stock-outs, viral load suppression (VLS) and viral load (VL) testing completion.

Using Media to Promote Public Awareness of Early Detection of Kaposi's Sarcoma in Africa.

Background: Despite its hallmark cutaneous presentation, most Kaposi's sarcoma (KS) in Africa is diagnosed too late for effective treatment. Early diagnosis will only be achievable if patients with KS present earlier for care. We hypothesized that public awareness about KS can be enhanced through exposure to common media.

Prevalence of viral load suppression, predictors of virological failure and patterns of HIV drug resistance after 12 and 48 months on first-line antiretroviral therapy: a national cross-sectional survey in Uganda.

Objectives: We implemented the WHO cross-sectional survey protocol to determine rates of HIV viral load (VL) suppression (VLS), and weighted prevalence, predictors and patterns of acquired drug resistance (ADR) in individuals with virological failure (VF) defined as VL ≥1000 copies/mL.

Methods: We enrolled 547 and 1064 adult participants on first-line ART for 12 (±3) months (ADR12) and ≥48 months (ADR48), respectively. Dried blood spots and plasma specimens were collected for VL testing and genotyping among the VFs.

Evaluation of HIV-1 rapid tests and identification of alternative testing algorithms for use in Uganda.

Introduction: The World Health Organization recommends that countries conduct two phase evaluations of HIV rapid tests (RTs) in order to come up with the best algorithms. In this report, we present the first ever such evaluation in Uganda, involving both blood and oral based RTs. The role of weak positive (WP) bands on the accuracy of the individual RT and on the algorithms was also investigated.

Successful Treatment of Human Plague with Oral Ciprofloxacin.

The US Food and Drug Administration recently approved ciprofloxacin for treatment of plague (Yersina pestis infection) based on animal studies. Published evidence of efficacy in humans is sparse. We report 5 cases of culture-confirmed human plague treated successfully with oral ciprofloxacin, including 1 case of pneumonic plague.

Virological Response and Antiretroviral Drug Resistance Emerging during Antiretroviral Therapy at Three Treatment Centers in Uganda.

Background: With the scale-up of antiretroviral therapy (ART), monitoring programme performance is needed to maximize ART efficacy and limit HIV drug resistance (HIVDR).

Methods: We implemented a WHO HIVDR prospective survey protocol at three treatment centers between 2012 and 2013. Data were abstracted from patient records at ART start (T1) and after 12 months (T2).

Seasonal pulses of Marburg virus circulation in juvenile Rousettus aegyptiacus bats coincide with periods of increased risk of human infection.

Marburg virus (family Filoviridae) causes sporadic outbreaks of severe hemorrhagic disease in sub-Saharan Africa. Bats have been implicated as likely natural reservoir hosts based most recently on an investigation of cases among miners infected in 2007 at the Kitaka mine, Uganda, which contained a large population of Marburg virus-infected Rousettus aegyptiacus fruit bats. Described here is an ecologic investigation of Python Cave, Uganda, where an American and a Dutch tourist acquired Marburg virus infection in December 2007 and July 2008.

Clinical characteristics, treatment and outcome of childhood Burkitt's lymphoma at the Uganda Cancer Institute.

Burkitt's lymphoma (BL) is a major cause of death among Ugandan children. We studied clinical characteristics and outcomes of childhood BL over time at the Uganda Cancer Institute (UCI). A total of 1217 children (766 boys, 451 girls, mean age 6.

MDM2 and CDKN1A gene polymorphisms and risk of Kaposi's sarcoma in African and Caucasian patients.

A single-nucleotide polymorphism in the MDM2 promoter (SNP309; rs2279744) causes elevated transcription of this major negative regulator of p53 in several cancer types. We investigated MDM2 SNP309 and CDKN1A (p21/Waf1/Cip1) codon 31 (rs1801270) polymorphisms in 86 cases of cutaneous Kaposi's sarcoma (KS) from African and Caucasian patients, and 210 healthy controls. A significant increase of the MDM2 SNP309 T/G genotype was observed among classic KS cases (odds ratio 2.

Schistosomiasis among recreational users of Upper Nile River, Uganda, 2007.

After recreational exposure to river water in Uganda, 12 (17%) of 69 persons had evidence of schistosome infection. Eighteen percent self-medicated with praziquantel prophylaxis immediately after exposure, which was not appropriate. Travelers to schistosomiasis-endemic areas should consult a travel medicine physician.

Risk of being seropositive for multiple human papillomavirus types among Finnish and Ugandan women.

Although infections with multiple human papillomavirus (HPV) types have been reported widely, more information is needed on the occurrence of the different types. We determined the distribution of seroprevalences to multiple HPV types in Finland and Uganda to compare the epidemiology of the different HPV types in the 2 populations. Serum samples were obtained from 2784 Finnish and 1964 Ugandan women (mean ages 22 y and 25 y, respectively) of whom 44% and 57%, respectively, had antibodies to at least 1 of the 7 HPV types (6, 11, 16, 18, 31, 33, 45) tested (p < 0.

Human herpesvirus type 8 variants circulating in Europe, Africa and North America in classic, endemic and epidemic Kaposi's sarcoma lesions during pre-AIDS and AIDS era.

Human herpesvirus-8 (HHV-8) variants have been found heterogeneously distributed among human populations living in diverse geographic regions, but their differential pathogenicity in Kaposi's sarcoma development remains controversial. In the present study, HHV-8 variant distribution has been analyzed in classic, iatrogenic, endemic as well as epidemic Kaposi's sarcoma (KS) during pre-AIDS and AIDS period (1971-2008) in countries with different KS incidence rate. DNA samples from cutaneous KS lesions of 68 patients living in Africa (n=23, Cameroon, Kenya and Uganda), Europe (n=34, Greece and Italy) and North America (n=11) have been subjected to PCR amplification of HHV-8 ORF 26, T0.

TP53 codon 72 polymorphism in classic, endemic and epidemic Kaposi's sarcoma in African and Caucasian patients.

Objectives: Several studies have examined the association of codon 72 polymorphism of the TP53 gene, encoding either arginine or proline, in several tumor types but none have investigated its role in Kaposi's sarcoma (KS) development.

Methods: In this prevalent case-control study, 67 cutaneous lesions of classic, iatrogenic, endemic as well as epidemic KS from African (n = 22) and Caucasian (n = 45) patients, and blood samples from 150 healthy controls (n = 57 African, n = 93 Caucasian) have been analyzed for arginine and proline allele distribution.

Results: Among African cases the proline homozygous, heterozygous and arginine homozygous genotype frequencies were 50.

Dose-modified oral chemotherapy in the treatment of AIDS-related non-Hodgkin's lymphoma in East Africa.

PURPOSE Africa is burdened by the AIDS epidemic and attendant increase in HIV/AIDS-related malignancies. Pragmatic approaches to therapeutic intervention could be of great value. Dose-modified oral chemotherapy for AIDS-related non-Hodgkin's lymphoma is one such approach.

Impact of HIV infection and Kaposi sarcoma on human herpesvirus-8 mucosal replication and dissemination in Uganda.

Introduction: Kaposi sarcoma (KS) is the leading cause of cancer in Uganda and occurs in people with and without HIV. Human herpesvirus-8 (HHV-8) replication is important both in transmission of HHV-8 and progression to KS. We characterized the sites and frequency of HHV-8 detection in Ugandans with and without HIV and KS.

Clinical characteristics and outcome of children with Burkitt lymphoma in Uganda according to HIV infection.

Background: Characteristics of children with Burkitt lymphoma (BL) and HIV infection have not been described in Uganda before.

Procedure: We reviewed records at Uganda Cancer Institute (UCI) for years 1994-2004, to compare clinical features and outcome of BL in children who are HIV positive and negative (HIV+, HIV-). As statistical methods we used Student's t-test, Chi-square and Kaplan-Meier's to compare both groups.

Intestinal parasites in Kaposi sarcoma patients in Uganda: indication of shared risk factors or etiologic association.

Kaposi sarcoma (KS) is endemic in Uganda and shares several risk factors with intestinal parasite infestation, including rural residence, contact with surface water, and walking barefoot, however, the significance of these ecologic relationships is unknown. We investigated these relationships among 1,985 Ugandan patients with cancer. Odds ratios (OR) were calculated using logistic regression.

Current investigations and treatment of Burkitt's lymphoma in Africa.

We reviewed the scientific literature on Burkitt's lymphoma (BL) in Africa in order to provide information on the current status of clinical care and the existing research challenges. BL epidemiology led to the discovery of the Epstein Barr virus, an important cause of several viral illnesses and malignancies. The incidence of BL has increased in the endemic areas of Africa, overlapping with the epidemic of HIV and increase of malaria.

Burkitt's lymphoma in Africa, a review of the epidemiology and etiology.

Burkitt's lymphoma (BL) was first described in Eastern Africa, initially thought to be a sarcoma of the jaw. Shortly it became well known that this was a distinct form of Non Hodgkin's lymphoma. The disease has given insight in all aspects of cancer research and care.
