Non-malarial febrile illnesses comprise of almost half of all fever presenting morbidities, among under-five children in sub-Saharan Africa. Studies have reported cases of prescription of antimalarial medications to these febrile under-fives who were negative for malaria. The treatment of these children with antimalarial medications increases incidences of antimalarial drug resistance as well as further morbidities and mortalities, due to failure to treat the actual underlying causes of fever. To identify clinical and demographic factors associated with treatment type (malarial/non-malarial) of non-malarial febrile illnesses (NMFI) in children aged ≤5 at the Kenyatta National Hospital in Nairobi, Kenya. A positivist epistemological approach, cross sectional descriptive study design was used. A structured questionnaire was used on a sample of 341 medical records of children aged ≤5 years to extract data on clinical examinations (recorded as yes or no), diagnostic test results, and demographic data on the child's sex and age. Descriptive and inferential analysis was applied to the data. Prescription of antimalarial drugs despite negative microscopy results was found in 44 (12.9%) of the children, with mortality reported in 48 (14.1%). Assessment of respiratory distress was 0.13 (0.03,0.58) times associated with less likelihood of prescribing an antimalarial in those with a negative microscopy. A male patient was 0.21 (0.05,0.89) times less likely to receive an intravenous antimalarial after a negative microscopy. Patients aged ˂1 with a negative microscopy result were more likely to receive an antimalarial than older children. There is a need to eliminate incorrect treatment of NMFI with antimalarial medication, while ensuring correct diagnosis and treatment of the specific illness occurs. This requires strengthening and adherence to diagnostic and treatment guidelines of febrile illnesses in under-fives, consequently reducing morbidities and mortalities associated with inadequate management of NMFIs.

1.5 million Kenyans are living with HIV/AIDS as per 2015 estimates. Though there is a notable decline in new HIV infections, continued effort is still needed to develop an efficacious, accessible and affordable HIV vaccine. HIV vaccine clinical trials bear risks, hence a need to understand volunteer motivators for enrolment, retention and follow-up. Understanding the factors that motivate volunteers to participate in a clinical trial can help to strategize, refine targeting and thus increase enrolment of volunteers in future HIV vaccine clinical trials. The health belief model classifies motivators into social benefits such as 'advancing research' and collaboration with science, and personal benefits such as health benefits and financial interests. A thematic analysis was carried out on data obtained from four HIV clinical trials conducted at KAVI-Institute of Clinical Research in Nairobi Kenya from 2009 to 2015. Responses were obtained from a Questionnaire administered to the volunteers during their screening visit at the research site. Of the 281 healthy, HIV-uninfected volunteers participating in this study; 38% were motivated by personal benefits including, 31% motivated by health benefits and 7% motivated by possible financial gains. In addition, 62% of the volunteers were motivated by social benefits with 20% of who were seeking to help their family/society/world while 42% were interested in advancing research. The majority of volunteers in the HIV vaccine trials at our site were motivated by social benefits, suggesting that altruism can be a major contributor to participation in HIV vaccine studies. Personal benefits were a secondary motivator for the volunteers. The motivators to volunteer in HIV clinical trials were similar across ages, education level and gender. Education on what is needed (including volunteer participation) to develop an efficacious vaccine could be the key to greater volunteer motivation to participate in HIV vaccine clinical trials.

The global burden of mycetoma, a debilitating, neglected tropical disease, is unknown, and patients struggle to complete treatment due to limited accessibility and affordability of medications. This communication highlights a landmark clinical trial conducted by the Mycetoma Research Center (MRC) at the University of Khartoum, Sudan, in partnership with the Drugs for Neglected Diseases initiative (DNDi) and Eisai Co., Ltd. (Eisai). Published in The Lancet Infectious Diseases, this clinical trial marks a significant advancement in mycetoma research and treatment. As the first randomised clinical trial assessing a new mycetoma treatment, it compared fosravuconazole with the current standard of care, itraconazole. While the trial found no dose of fosravuconazole to be superior to itraconazole, it did reveal that fosravuconazole presented no new safety concerns. Moreover, its lower pill burden, reduced risk of drug–drug interactions, and the fact that it can be taken without food make it a more feasible alternative to the relatively expensive and less accessible itraconazole for treating eumycetoma. This clinical trial, conducted in a difficult socio-political situation in Sudan, was only made possible by the exceptional efforts of the MRC. This groundbreaking study not only advances treatment options for mycetoma but also enhances research capacity in an endemic region, paving the way for future investigations into neglected tropical diseases.

Eumycetoma is an implantation mycosis characterised by a large subcutaneous mass in the extremities commonly caused by the fungus Madurella mycetomatis. Despite the long duration of treatment, commonly a minimum of 12 months, treatment failure is frequent and can lead to amputation. We aimed to compare the efficacy of two doses of fosravuconazole, a synthetic antifungal designed for use in onychomycosis and repurposed for mycetoma, with standard-of-care itraconazole, both in combination with surgery. This phase 2, randomised, double-blind, active-controlled, superiority trial was conducted in a single centre in Sudan. Patients with eumycetoma caused by M mycetomatis, who were aged 15 years or older, with a set lesion diameter (>2 cm and ≤16 cm) requiring surgery were included. There was a limit of 20 female patients in the initial enrolment, owing to preclinical toxicity concerns. Exclusion criteria included previous surgical or medical treatment for eumycetoma; presence of loco-regional lymphatic extension; osteomyelitis, or other bone involvement; pregnancy or lactation; severe concomitant diseases; a BMI under 16 kg/m2; contraindication to use of the study drugs; pre-existing liver disease; lymphatic extension; osteomyelitis; transaminase levels more than two times the laboratory's upper limit of normal, or elevated levels of alkaline phosphatase or bilirubin; or any history of hypersensitivity to any azole antifungal drug. Patients were randomly allocated in a 1:1:1 ratio to 300 mg fosravuconazole weekly for 12 months (group 1); 200 mg fosravuconazole weekly for 12 months (group 2); or 400 mg itraconazole daily for 12 months (group 3) using a random number list with non-disclosed fixed blocks of size 12, with equal allocation to each of the three arms within a block. To ensure masking between groups, placebo pills were used to disguise the difference in dosing schedules. All groups took pills twice daily with meals. In all groups, surgery was performed at 6 months. The primary outcome was complete cure at end of treatment at the month 12 visit, as evidenced by absence of mycetoma mass, sinuses, and discharge; normal ultrasonography or MRI examination of the eumycetoma site; and, if a mass was present, negative fungal culture from the former mycetoma site. The primary outcome was assessed in the modified intention-to-treat (mITT) population (all patients who received one or more treatment dose with one or more primary efficacy assessment). Safety was assessed in all patients who received one or more doses of the study drug. This study is registered with ClinicalTrials.gov (NCT03086226) and is complete. Between May 9, 2017, and June 10, 2021, 104 patients were randomly allocated (34 in group 1 and 2, respectively, and 36 in group 3). 86 (83%) of 104 patients were male and 18 (17%) patients were female. After an unplanned second interim analysis, the study was terminated early for futility. Complete cure at 12 months in the mITT population was 17 (50%) of 34 (95% CI 32–68) for group 1, 22 (65%) of 34 (47–80) for group 2, and 27 (75%) of 36 (58–88) in group 3. Neither dose of fosravuconazole was superior to itraconazole (p=0·35 for 200 mg fosravuconazole vs p=0·030 for 300 mg fosravuconazole). 83 patients had a total of 205 treatment-emergent adverse events, and two patients had serious adverse events that led to discontinuation, neither related to treatment. Treatment with either dose of fosravuconazole was not superior to itraconazole, and the two doses had a numerically lower efficacy. However, fosravuconazole presented no new safety signals, and its lower pill burden and reduced risk of drug–drug interactions compared with the relatively expensive and inaccessible itraconazole suggests further research into effective treatments with a shorter duration and higher cure rate, without the need for surgery are warranted.

Mycetoma is a debilitating neglected tropical disease that affects individuals worldwide, particularly in regions where there is poverty and limited health care access. The Mycetoma Research Center (MRC), based in Khartoum, Sudan, provides a sustainable, holistic approach to patient care as the only World Health Organization collaborating center for mycetoma. We describe MRC activities that align with the United Nations’ Sustainable Development Goals to control mycetoma in Sudan and globally.

IntroductionLong-acting reversible contraceptives (LARCs) are effective birth control methods that do not depend on patient compliance. They include injections, intrauterine devices (IUDs) and sub-dermal implants. Kenya had over 1.5 million people living with HIV in 2015 with female sex workers (FSWs) known to be at a higher risk for both unintended pregnancies and HIV infection. HIV clinical trials test novel compounds whose effects in fetuses are unknown thus require female subjects to use LARCs to avoid pregnancies. Clinical trials also aim to recruit high-risk individuals to closely study infection dynamics in a representative natural infection cohort. Therefore, it is crucial to investigate the preference for contraception in a HIV-high risk population such as FSWs to inform the design and conduct of HIV vaccine clinical trials, especially in the resource-limited Sub-Saharan Africa. The on-going Simulated Vaccine Efficacy Trial (SiVET) Study at KAVI-ICR may provide answers to this.MethodsData on use of modern contraception methods (pills, injectables, implants, IUDs and surgicals) are collected from FSWs during screening, and confirmed by a contraceptive card or the presence of an implant or IUD strings. The proportion of women per method used is determined.ResultsSeventy nine women with an age range of 18–50 years have been screened since 2016. Most (89%, n=73) were already using contraception. Of these; 63% (n=46) were on injectables, 22% on implants (n=16), 8% IUCDs (n=6), 4% pills (n=3) and 3% (n=2) had undergone a surgical method. No pregnancy while two HIV infections were reported at screening.ConclusionThere is high contraceptive use among the FSWs with the majority preferring injectables. This practice is encouraging and thus, discontinuation of volunteers from the clinical trial due to pregnancy is unlikely. At the end of trial in 2018, data will be collected on changes in contraceptive, number of pregnancies, condom use, HIV infections and experience on use of the contraception.

Background Mycetoma is a chronic, progressively destructive infection that can result in severe disability and limb loss. In Ethiopia, diagnostic capacity and access to effective treatment remain limited, and the burden of mycetoma is poorly characterized. Recent clinical observations from the Afar Region suggest a high frequency of advanced disease and amputation, yet systematic evidence on the burden is lacking. This study aimed to describe the clinical burden of mycetoma, diagnostic and treatment practices, care-seeking patterns, and the extent of limb amputation at Dubti General Hospital in Afar region, northeastern Ethiopia. We conducted a facility-based retrospective review of all patients with a clinical diagnosis of mycetoma managed at Dubti General Hospital between September 2020 and August 2025. Demographic characteristics, clinical presentation, diagnostic investigations, treatment modalities, disability status, and surgical outcomes were summarized descriptively. Factors associated with delayed presentation (>12 months from symptom onset) were assessed using multivariable logistic regression. A total of 143 patients were identified, with a mean age of 30.9 years (SD ± 11.7); 79% were male, 85.3% resided in rural areas, and 46% were pastoralists. All cases involved the lower limb and presented with localized swelling. Pain (90.9%), warmth (54.5%), sinus formation (42.7%), and discharge (40.6%) were common. Diagnosis relied primarily on clinical assessment alone (58.7%), with limited use of imaging and biopsy. The mean duration of illness before first presentation was 33.8 months (SD ± 29), and 89.5% of patients presented after more than 12 months of symptoms. Compared with farmers, merchants had lower odds of delayed presentation (AOR = 0.89, 95% CI: 0.27–0.59). Nineteen patients (13.3%) underwent limb amputation, accounting for 23.5% of all orthopaedic amputations performed at the hospital during the study period. Disability at presentation was frequent, with 14.0% of patients experiencing severe motor impairment. Mycetoma in Afar predominantly affects young rural men and presents almost exclusively with advanced lower-limb disease. Profound diagnostic limitations, delayed care-seeking, and restricted surgical options contribute to poor outcomes. Integrating mycetoma into national neglected tropical disease strategies, strengthening early detection and diagnostic services, ensuring consistent access to essential medications, and expanding limb-sparing surgical capacity are critical to reducing preventable disability and aligning Ethiopia’s response with global NTD control targets.

There is limited data on antibiotic treatment in hospitalized neonates in low- and middle-income countries (LMICs). We aimed to describe patterns of antibiotic use, pathogens, and clinical outcomes, and to develop a severity score predicting mortality in neonatal sepsis to inform future clinical trial design. Hospitalized infants <60 days with clinical sepsis were enrolled during 2018 to 2020 by 19 sites in 11 countries (mainly Asia and Africa). Prospective daily observational data was collected on clinical signs, supportive care, antibiotic treatment, microbiology, and 28-day mortality. Two prediction models were developed for (1) 28-day mortality from baseline variables (baseline NeoSep Severity Score); and (2) daily risk of death on IV antibiotics from daily updated assessments (NeoSep Recovery Score). Multivariable Cox regression models included a randomly selected 85% of infants, with 15% for validation. A total of 3,204 infants were enrolled, with median birth weight of 2,500 g (IQR 1,400 to 3,000) and postnatal age of 5 days (IQR 1 to 15). 206 different empiric antibiotic combinations were started in 3,141 infants, which were structured into 5 groups based on the World Health Organization (WHO) AWaRe classification. Approximately 25.9% (n = 814) of infants started WHO first line regimens (Group 1-Access) and 13.8% (n = 432) started WHO second-line cephalosporins (cefotaxime/ceftriaxone) (Group 2-\"Low\" Watch). The largest group (34.0%, n = 1,068) started a regimen providing partial extended-spectrum beta-lactamase (ESBL)/pseudomonal coverage (piperacillin-tazobactam, ceftazidime, or fluoroquinolone-based) (Group 3-\"Medium\" Watch), 18.0% (n = 566) started a carbapenem (Group 4-\"High\" Watch), and 1.8% (n = 57) a Reserve antibiotic (Group 5, largely colistin-based), and 728/2,880 (25.3%) of initial regimens in Groups 1 to 4 were escalated, mainly to carbapenems, usually for clinical deterioration (n = 480; 65.9%). A total of 564/3,195 infants (17.7%) were blood culture pathogen positive, of whom 62.9% (n = 355) had a gram-negative organism, predominantly Klebsiella pneumoniae (n = 132) or Acinetobacter spp. (n = 72). Both were commonly resistant to WHO-recommended regimens and to carbapenems in 43 (32.6%) and 50 (71.4%) of cases, respectively. MRSA accounted for 33 (61.1%) of 54 Staphylococcus aureus isolates. Overall, 350/3,204 infants died (11.3%; 95% CI 10.2% to 12.5%), 17.7% if blood cultures were positive for pathogens (95% CI 14.7% to 21.1%, n = 99/564). A baseline NeoSep Severity Score had a C-index of 0.76 (0.69 to 0.82) in the validation sample, with mortality of 1.6% (3/189; 95% CI: 0.5% to 4.6%), 11.0% (27/245; 7.7% to 15.6%), and 27.3% (12/44; 16.3% to 41.8%) in low (score 0 to 4), medium (5 to 8), and high (9 to 16) risk groups, respectively, with similar performance across subgroups. A related NeoSep Recovery Score had an area under the receiver operating curve for predicting death the next day between 0.8 and 0.9 over the first week. There was significant variation in outcomes between sites and external validation would strengthen score applicability. Antibiotic regimens used in neonatal sepsis commonly diverge from WHO guidelines, and trials of novel empiric regimens are urgently needed in the context of increasing antimicrobial resistance (AMR). The baseline NeoSep Severity Score identifies high mortality risk criteria for trial entry, while the NeoSep Recovery Score can help guide decisions on regimen change. NeoOBS data informed the NeoSep1 antibiotic trial (ISRCTN48721236), which aims to identify novel first- and second-line empiric antibiotic regimens for neonatal sepsis.

ObjectiveTo assess pharmacokinetics and changes to sodium levels in addition to adverse events (AEs) associated with fosfomycin among neonates with clinical sepsis.DesignA single-centre open-label randomised controlled trial.SettingKilifi County Hospital, Kenya.Patients120 neonates aged ≤28 days admitted being treated with standard-of-care (SOC) antibiotics for sepsis: ampicillin and gentamicin between March 2018 and February 2019.InterventionWe randomly assigned half the participants to receive additional intravenous then oral fosfomycin at 100 mg/kg two times per day for up to 7 days (SOC-F) and followed up for 28 days.Main outcome(s) and measure(s)Serum sodium, AEs and fosfomycin pharmacokinetics.Results61 and 59 infants aged 0–23 days were assigned to SOC-F and SOC, respectively. There was no evidence of impact of fosfomycin on serum sodium or gastrointestinal side effects. We observed 35 AEs among 25 SOC-F participants and 50 AEs among 34 SOC participants during 1560 and 1565 infant-days observation, respectively (2.2 vs 3.2 events/100 infant-days; incidence rate difference −0.95 events/100 infant-days (95% CI −2.1 to 0.20)). Four SOC-F and 3 SOC participants died. From 238 pharmacokinetic samples, modelling suggests an intravenous dose of 150 mg/kg two times per day is required for pharmacodynamic target attainment in most children, reduced to 100 mg/kg two times per day in neonates aged <7 days or weighing <1500 g.Conclusion and relevanceFosfomycin offers potential as an affordable regimen with a simple dosing schedule for neonatal sepsis. Further research on its safety is needed in larger cohorts of hospitalised neonates, including very preterm neonates or those critically ill. Resistance suppression would only be achieved for the most sensitive of organisms so fosfomycin is recommended to be used in combination with another antimicrobial.Trial registration number NCT03453177.

Attenuated varicella zoster virus (VZV) is a promising vector for recombinant vaccines. Because human immunodeficiencyvirus (HIV) vaccines are believed to require mucosal immunogenicity, we characterized mucosal VZV-specific humoral immunity following VZVOka vaccination. Adult Kenyan VZV-seropositive women (n = 44) received a single dose of the live zoster VZVOka vaccine. The anamnestic responses to the virus were followed longitudinally in both plasma and mucosal secretions using an in-house glycoprotein enzyme-linked immunosorbent assay and safety and reactogenicity monitored. VZV seroprevalence and baseline responses to the virus were also characterized in our cohorts (n = 288). Besides boosting anti-VZV antibody responses systemically, vaccination also boosted anti-VZV immunity in the cervicovaginal mucosa with a 2.9-fold rise in immunoglobulin G (P < .0001) and 1.6-fold rise in immunoglobulin A (IgA) (P = .004) from the time before immunization and 4 weeks postvaccination. Baseline analysis demonstrated high avidity antibodies at the gastrointestinal and genital mucosa of VZV-seropositive women. Measurement of VZV-specific IgA in saliva is a sensitive tool for detecting prior VZV infection. VZVOka vaccine was safe and immunogenic in VZV-seropositive adult Kenyan women. We provided compelling evidence of VZV ability to induce genital mucosa immunity. NCT02514018.
