    (BMC Nephrology, 2015) Bagasha, Peace; Nakwagala, Frederick; Kwizera, Arthur; Ssekasanvu, Emmanuel; Kalyesubula, Robert
    Acute kidney injury (AKI) is a common complication of sepsis. We determined the prevalence of AKI among adult patients with sepsis on the medical wards in a low-income country and described their clinical pattern and outcomes at discharge. Methods: We conducted a cross-sectional study of sepsis-related AKI on the adult medical wards of Mulago National Referral Hospital between January and April 2013. All patients meeting the American College of Chest Physicians (ACP) sepsis criteria were recruited. Demographic, clinical, laboratory and ultrasonography data were recorded and all patients with AKI were followed up to a maximum of 2 weeks. Proportional analysis was carried out and odds ratios with 95% confidence intervals were calculated in the bivariate analysis. Results: Of 387 patients recruited, 217 (55.6%) were male and the average age was 37 years (range18–90 years). The prevalence of sepsis-related AKI was 16.3%. Age >59 years (p = 0.023), a postural drop in systolic blood pressure of >9 mmHg (p = 0.015) and a white blood cell count >12,000 cells/mL (p = 0.003) were significantly associated with AKI. In-hospital mortality among patients with AKI was 21% (13/63). 59% (20/49) of patients who were discharged alive or were still on the wards after 2 weeks had persistent kidney injury. Acute Kidney Injury Network (AKIN) Stage 3 was significantly associated with persistence of kidney injury (p = 0.001). None of the patients requiring dialysis or ICU care received either because of limited access. Conclusions: The prevalence, morbidity and mortality due to AKI among sepsis patients in Uganda is very high and limited access to dialysis and ICU care is a major factor in poor outcomes for these patients.

    Charcot arthropathy of the diabetic foot in a sub-Saharan tertiary hospital: a cross- sectional study
    (BioMedical Central, 2019) Wanzou, Jean Paul Vwakya; Sekimpi, Patrick; Komagum, Johnson Owonda; Nakwagala, Frederick; Mwaka, Erisa Sabakaki
    Abstract Background: Charcot foot arthropathy is a potentially limb-threatening condition that leads to progressive destruction of the bones and joints in the neuropathic foot. One of its main causes is diabetes mellitus whose prevalence is steadily increasing. The acute phase is often misdiagnosed thus leading to foot deformity, ulceration and increased risk of amputation. There is a paucity of literature on this condition from sub-Saharan Africa. This study aimed at determining the extent of Charcot foot arthropathy, the radiological patterns of Charcot foot arthropathy and patient’s factors associated with Charcot foot arthropathy among adult patients with longstanding diabetes in an African setting. Methods: This was a cross-sectional study that was carried at a national referral and university teaching hospital in Kampala, Uganda. One hundred patients with longstanding diabetes mellitus were consecutively recruited. Patients with a history of having diabetes mellitus for at least seven years since diagnosis were considered to have a longstanding disease. Clinical assessment of both feet was done. Weight-bearing radiographs of the selected foot were taken and evaluated using the Sanders and Frykberg and modified Eichenholtz classifications. A blood sample was taken for glycosylated haemoglobin (HbA1c). Data were summarized using descriptive statistics and student t-test. Results: The proportion of Charcot foot arthropathy among patients with longstanding diabetes was 12% of which one-third (4 out of 12) were acute cases. Fifty percent of the lesions were in the forefoot and 50% in the midfoot. Seventeen percent of lesions were at the inflammatory stage of the modified Eichenholtz classification, 50% at the developmental stage, 25% at the healing stage, and 8% at the remodelling stage. An abnormal foot radiograph was significantly associated with Charcot foot arthropathy among patients with longstanding diabetes. Conclusion: Charcot foot arthropathy is fairly common in patients with longstanding diabetes mellitus in these settings with one third of patients presenting in the early acute phase. An abnormal weight-bearing radiograph was an associated factor of Charcot foot arthropathy among this specific group of patients. To reduce on the morbidity and limb threatening sequelae of this condition, clinicians are therefore advised to routinely examine the feet of patients with diabetes and send those with suspicious signs and symptoms for radiographic assessment.

    COVID-19, HIV-Associated Cryptococcal Meningitis, Disseminated Tuberculosis and Acute Ischaemic Stroke: A Fatal Foursome
    (Infection and Drug Resistance, 2021) Bongomin, Felix; Sereke, Senai Goitom; Okot, Jerom; Katsigazi, Ronald; Kiiza Kandole, Tadeo; Oriekot, Anthony; Olum, Ronald; Atukunda, Angella; Baluku, Joseph Baruch; Nakwagala, Frederick
    Several viral, bacterial and fungal co-infections have been associated with increased morbidity and mortality among patients with COVID-19. We report a fatal case of severe COVID-19 pneumonia in a patient with a recent diagnosis of advanced HIV disease complicated by cryptococcal meningitis, disseminated tuberculosis and acute ischemic stroke. Case Presentation: A 37-year-old Ugandan woman was diagnosed with HIV infection 8 days prior to her referral to our center. She was antiretroviral naïve. Her chief complaints were worsening cough, difficulty in breathing, fever and altered mental status for 3 days with a background of a 1-month history of coughing with associated drenching night sweats and weight loss. The reverse transcriptase–polymerase chain reaction for SARS-CoV-2 of her nasopharyngeal swab sample was positive. Chest radiograph demonstrated military pattern involvement of both lungs. The serum and cerebrospinal fluid cryptococcal antigen tests were positive. Urine lipoarabinomannan and sputum GeneXpert were positive for Mycobacterium tuberculosis. Computed tomography of the brain showed a large acute ischemic infarct in the territory of the right middle cerebral artery. Regardless of the initiation of treatment, that is, fluconazole 1200 mg once daily, enoxaparin 60 mg, intravenous (IV) dexamethasone 6 mg once daily, oral fluconazole 1200 mg once daily, IV piperacillin/tazobactam 4.5 g three times daily and oxygen therapy, the patient passed on within 36 hours of admission. Conclusion: Co-infections worsen COVID-19 outcomes.

    A Demonstration of Peer Support for Ugandan Adults With Type 2 Diabetes
    (International journal of behavioral medicine, 2015) Baumann, Linda C.; Nakwagala, Frederick; Nankwanga, Betty; Ejang, Jospehine; Nambuya, Agatha
    Background By 2030, 80 % of people with diabetes will be living in developing countries. Purpose The purpose of this pre-post quasi-experimental study was to test the feasibility of a peer intervention to improve the following: (1) diabetes self-care behaviors, (2) glycemic control, (3) social support and emotional well-being, (4) linkages to health care providers, and (5) to assess the sustainability of the intervention 18 months later. Method Participants were adults with type 2 diabetes who resided in rural Uganda. Participants (n=46) attended a 1- day diabetes education program and agreed to make weekly contacts over 4 months with each other by phone or in person to assist with daily management, provide social and emotional support, and encourage appropriate contact with health care providers. Results Results indicated improvement in glycosylated hemoglobin (A1C), diastolic blood pressure, and eating behaviors. Conclusions A short-term peer support program was a feasible intervention to improve diabetes care in rural Uganda. Participants were successfully recruited and retained, and they experienced positive behavioral and physiologic outcomes. Elements of the intervention were sustained 18 months after the intervention.

    Research site monitoring for compliance with ethics regulatory standards: review of experience from Uganda
    (BMC Medical Ethics, 2013) Ochieng, Joseph; Ecuru, Julius; Nakwagala, Frederick; Kutyabami, Paul
    On site monitoring of research is one of the most effective ways to ensure compliance during research conduct. However, it is least carried out primarily for two reasons: presumed high costs both in terms of human resources and finances; and the lack of a clear framework for undertaking site monitoring. In this paper we discuss a model for research site monitoring that may be cost effective and feasible in low resource settings. Methods: This was a retrospective review of research site monitoring reports covering a period of four years. Results: The monitoring was conducted by the Uganda National Council for Science and Technology, the National Drug Authority and the National HIV/AIDS Research and Ethics Committee over the period 2007 to 2010. The monitoring team was usually three members comprising of two experts in research ethics and an assistant. A total of 28 site monitoring visits covering 40 research projects were reviewed. 25% of the site monitoring reports revealed violation of the regulatory requirement for valid ethical approval. 36% of the site reports showed some instances of informed consent violation, 28% showed violation of the rights and welfare of research participants, 38% revealed that sites did not report SAEs to regulatory authorities and many sites lacked adequate GCP and GCLP. However, most of the sites monitored had adequate facilities to conduct the respective studies and good working practices. Conclusion: This model employed by the monitoring teams to evaluate research compliance is effective in auditing ethical practice. Compliance monitoring is feasible and affordable in a resource limited setting. Research protocol non compliance is still a major problem in Uganda, and there is need for a pro-active approach to this vice by all stake holders if ethical conduct of research is to be achieved.
