Self-management Intervention for Reducing Epilepsy Burden Among Adult Ugandans With Epilepsy (Smart-u), Randomised Clinical Trial Protocol.

Background: Epilepsy is a common chronic brain disorder globally affecting people of all ages, with the majority living in developing countries. The introduction of epilepsy self-management approaches to help people with epilepsy is urgently needed to influence epilepsy-related outcomes. This 2-site randomised controlled trial building on promising preliminary data is intended to explore this further. Methods: A total of 188 adult people with epilepsy (PWE) attending the neurology clinics at Mulago and Mbarara hospitals and consent to participate in the study. They will be randomised into intervention versus enhanced treatment control (eTAU) study groups. The intervention group will receive 12-week "intensive" educational sessions and a 12-week remotely accessed telephone follow-up stage. The controls will continue in their usual care supplemented by written materials on epilepsy in their preferred language and tailored to the reading level of most patients at the clinic. SMART-U consists of 2 main components: a 12-week "intensive" group format stage and a 12-week remotely accessed telephone follow-up stage. SMART-U will be assessed for acceptability, fidelity, and efficacy compared to eTAU. The primary study outcome is the mean change in cumulative past 24-week seizure frequency (24 weeks prior to the study baseline compared to the 24-week follow-up). Seizure frequency will be via self-report with corroboration by family/support system informants whenever possible. Participants will self-report their seizure frequency (numeric count) that they experienced between baseline and 13 weeks and again between 13 and 24 weeks and the mean change from baseline to 24 weeks in QOL. Discussion: The curriculum-guided Self-Management intervention for Reducing The epilepsy burden among Ugandans (SMART-U) program is anticipated to reduce the epilepsy burden seizure frequency and improve other health outcomes, including depression, functional status and health resource use. Trial Registration Number TRN: NCT06139198. Date of registration: 14th November 2023.

Knowledge, attitudes, and adherence relating to COVID-19 and its prevention measures in high-risk districts of Uganda in 2020.

Introduction: COVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. There were no licensed vaccines or explicit medicines available for treatment at the time of conducting this study. Public health and social measures (PHSM) have been widely adopted to reduce the transmission of COVID-19. Hence, assessing people's knowledge, attitudes, and adherence/practices related to the management of COVID-19 is crucial for identifying the factors that may promote or hinder adherence to the implementation of PHSM. Methods: We conducted a cross-sectional study in the Amuru, Kyotera, Wakiso, and Kampala districts of Uganda. We used a simple random sampling technique to select households and conducted face-to-face interviews in selected households. We administered questionnaires to respondents to assess the factors that promote or hinder adherence to and knowledge about PHSM implementation. We used a Likert scale to assess respondents' attitudes toward COVID-19. Results: Out of the 270 respondents, 54 (20%), 73 (27%), 42 (15.6%), and 101 (37.4%) were from the Kampala, Amuru, Wakiso, and Kyotera districts, respectively. Most of the respondents had adequate knowledge (72.2%), a high level of adherence (63.7%), and approximately 57.8% had good attitudes relating to COVID-19 and its prevention measures. An inferential analysis revealed that people from the Kampala district had higher chances (odds ratio = 4.668) of having a high level of knowledge compared to people from the Amuru district. It was also found that respondents who had a high level of (adequate) knowledge were twice as likely to have good attitudes compared to those with a low level of knowledge. In addition, people with good attitudes were 2.5 times as likely to adhere to the COVID-19 prevention measures compared to those with poor attitudes. Conclusion: Most respondents had limited knowledge though the majority of them had adopted practices to prevent the spread of COVID-19. Respondents with low knowledge of COVID-19 need to be targeted, to improve their attitude toward the disease and their adherence to safe prevention practices.

Outbreak of cutaneous anthrax associated with handling meat of dead cows in Southwestern Uganda, May 2018.

BACKGROUND: Anthrax is a zoonotic infection caused by the bacteria Bacillus anthracis. Humans acquire cutaneous infection through contact with infected animals or animal products. On May 6, 2018, three cows suddenly died on a farm in Kiruhura District. Shortly afterwards, a sub-county chief in Kiruhura District received reports of humans with suspected cutaneous anthrax in the same district. The patients had reportedly participated in the butchery and consumption of meat from the dead cows. We investigated to determine the magnitude of the outbreak, identify exposures associated with illness, and suggest evidence-based control measures. METHODS: We conducted a retrospective cohort study among persons whose households received any of the cow meat. We defined a suspected human cutaneous anthrax case as new skin lesions (e.g., papule, vesicle, or eschar) in a resident of Kiruhura District from 1 to 26 May 2018. A confirmed case was a suspected case with a lesion testing positive for B. anthracis by polymerase chain reaction (PCR). We identified cases through medical record review at Engari Health Centre and active case finding in the community. RESULTS: Of the 95 persons in the cohort, 22 were case-patients (2 confirmed and 20 suspected, 0 fatal cases) and 73 were non-case household members. The epidemic curve indicated multiple point-source exposures starting on May 6, when the dead cows were butchered. Among households receiving cow meat, participating in slaughtering (RR = 5.3, 95% CI 3.2-8.3), skinning (RR = 4.7, 95% CI = 3.1-7.0), cleaning waste (RR = 4.5, 95% CI = 3.1-6.6), and carrying meat (RR = 3.9, 95% CI = 2.2-7.1) increased the risk of infection. CONCLUSIONS: This cutaneous anthrax outbreak was caused by handling infected animal carcasses. We suggested to the Ministry of Agriculture, Animal Industry and Fisheries to strengthen surveillance for possible veterinary anthrax and ensure that communities do not consume carcasses of livestock that died suddenly. We also suggested that the Ministry of Health equip health facilities with first-line antibiotics for community members during outbreaks.

Investigation of possible preventable causes of COVID-19 deaths in the Kampala Metropolitan Area, Uganda, 2020-2021.

BACKGROUND: Identifying preventable causes of COVID-19 deaths is key to reducing mortality. We investigated possible preventable causes of COVID-19 deaths over a six-month period in Uganda. METHODS: A case-patient was a person testing reverse transcription polymerase chain reaction-positive for SARS-CoV-2 who died in Kampala Metropolitan Area hospitals from August 2020 to February 2021. We reviewed records and interviewed health workers and case-patient caretakers. RESULTS: We investigated 126 (65%) of 195 reported COVID-19 deaths during the investigation period; 89 (71%) were male, and the median age was 61 years. A total of 98 (78%) had underlying medical conditions. Most (118, 94%) had advanced disease at admission to the hospital where they died. A total of 44 (35%) did not receive a COVID-19 test at their first presentation to a health facility despite having consistent symptoms. A total of 95 (75%) needed intensive care unit admission, of whom 45 (47%) received it; 74 (59%) needed mechanical ventilation, of whom 47 (64%) received it. CONCLUSION: Among hospitalized patients with COVID-19 who died in this investigation, early opportunities for diagnosis were frequently missed, and there was inadequate intensive care unit capacity. Emphasis is needed on COVID-19 as a differential diagnosis, early testing, and care-seeking at specialized facilities before the illness reaches a critical stage. Increased capacity for intensive care is needed.

Factors associated with poor treatment outcomes among tuberculosis patients in Kyangwali Refugee Settlement, Uganda, 2016-2017.

Communicable diseases, alone or in combination with malnutrition, account for most deaths in complex emergencies including refugee settings. Tuberculosis and HIV/AIDS are increasingly becoming an important cause of morbidity and mortality in refugee settings. We described the treatment outcomes of TB patients and explored factors associated with treatment outcomes among TB patients attending two facilities in Kyangwali Refugee Settlement in Kikuube District, 2016-2017. We abstracted data on laboratory-confirmed patient data from TB registers from 2016 to 2017, in Kikuube Health Centre IV and Rwenyawawa Health Centre II, both located in Kyangwali Refugee Settlement. We abstracted data on socio-demographic variables including age and sex. Other variables were height, weight, final treatment outcomes, demographics, HIV status, TB treatment category, and history of TB. Treatment outcomes were categorized into favorable (including patients who were cured or those who completed treatment) and unfavorable (those in whom treatment failed, those who died, those lost to follow-up, or those not evaluated). We used logistic regression to identify factors associated with unfavorable treatment outcomes. We identified a total of 254 TB patients with a median age of 36 (IQR 26-48) years; 69% (175) were male and 54% (137) were refugees. The median weight was 50.4 kg (range 4-198). Overall, 139 (55%) had favorable outcomes while 115 (45%) had unfavorable outcomes. Refugees formed 53% (71) of those with favorable outcomes and 47% (63) of those with unfavorable outcomes 63(47%). We found that increasing age was statistically associated with unfavorable outcomes, while diagnosis with MDR-TB was associated with decreased odds for unfavorable treatment outcomes. The treatment success rate was lower compared to 85% recommended by WHO. However, the rates are similar to that reported by other studies in Uganda. Innovative approaches to improve treatment success rates with particular focus on persons aged 41-80 years should be devised.

Sporadic Rift Valley Fever Outbreaks in Humans and Animals in Uganda, October 2017-January 2018.

Introduction: Rift Valley fever (RVF) is a mosquito-borne viral zoonosis. The Uganda Ministry of Health received alerts of suspected viral haemorrhagic fever in humans from Kiruhura, Buikwe, Kiboga, and Mityana districts. Laboratory results from Uganda Virus Research Institute indicated that human cases were positive for Rift Valley fever virus (RVFV) by polymerase chain reaction. We investigated to determine the scope of outbreaks, identify exposure factors, and recommend evidence-based control and prevention measures. Methods: A suspected case was defined as a person with acute fever onset, negative malaria test result, and at least two of the following symptoms: headache, muscle or joint pain, bleeding, and any gastroenteritis symptom (nausea, vomiting, abdominal pain, diarrhoea) in a resident of Kiruhura, Buikwe, Mityana, and Kiboga districts from 1st October 2017 to 30th January 2018. A confirmed case was defined as a suspected case with laboratory confirmation by either detection of RVF nucleic acid by reverse-transcriptase polymerase chain reaction (RT-PCR) or demonstration of serum IgM or IgG antibodies by ELISA. Community case finding was conducted in all affected districts. In-depth interviews were conducted with human cases that were infected with RVF who included herdsmen and slaughterers/meat handlers to identify exposure factors for RVF infection. A total of 24 human and 362 animal blood samples were tested. Animal blood samples were purposively collected from farms that had reported stormy abortions in livestock and unexplained death of animals after a short illness (107 cattle, 83 goats, and 43 sheep). Convenient sampling for the wildlife (10 zebras, 1 topi, and 1 impala) was conducted to investigate infection in animals from Kiruhura, Buikwe, Mityana, and Kiboga districts. Human blood was tested for anti-RVFV IgM and IgG and animal blood for anti-RVFV IgG. Environmental assessments were conducted during the outbreaks in all the affected districts. Results: Sporadic RVF outbreaks occurred from mid-October 2017 to mid-January 2018 affecting humans, domestic animals, and wildlife. Human cases were reported from Kiruhura, Buikwe, Kiboga, and Mityana districts. Of the 24 human blood samples tested, anti-RVFV IgG was detected in 7 (29%) human samples; 1 human sample had detectable IgM only, and 6 had both IgM and IgG. Three of the seven confirmed human cases died among humans. Results from testing animal blood samples obtained from Kiruhura district indicated that 44% (64/146) cattle, 46% (35/76) goats, and 45% (9/20) sheep tested positive for RVF. Among wildlife, (1/10) zebras, (1/1) topi, and (1/1) impala tested positive for RVFV by serological tests. One blood sample from sheep in Kiboga district tested RVFV positive. All the human cases were exposed through contact or consumption of meat from infected animals. Conclusion: RVF outbreaks occurred in humans and animals in Kiruhura, Buikwe, Mityana, and Kiboga districts. Human cases were potentially infected through contact with infected animals and their products.

Knowledge, perceptions and effects of Ebola virus disease outbreak on the pig value chain in the agro-pastoralist district of Luwero, Central Uganda.

BACKGROUND: Ebola Virus Disease (EVD) outbreaks have a significant impact on the health and wellbeing, and livelihoods of communities. EVD response interventions particularly affect the food value chain, and income security of pig farmers in agro-pastoral communities. Despite the enormous effort of EVD response interventions, there is paucity of information towards EVD among those involved in the pig value chain, as well as the effect of EVD outbreaks on the pig value chain. This study therefore, assessed the knowledge, perceptions on the occurrence of Ebola and its effects on the pig value chain in the agro-pastoral district of Luweero, Central Uganda. METHODS: A cross sectional study was conducted in two parishes of Ssambwe and Ngalonkulu, Luwero district. A total of 229 respondents were included in the study. Structured questionnaires, key informant interviews and focus group discussions were conducted to collect data. Quantitative data was analysed using SPSS version 22 while qualitative data was analysed using thematic content analysis. RESULTS: Of the 229 respondents, 95.6% could recall the occurrence of the last EVD outbreak in their locality. About 24.5% associated EVD with touching pigs or eating pork. Regarding knowledge, 194 (84.7%) correctly associated EVD with handling Ebola infected persons, 191 (83.4%) with migration of people from endemic areas, 148 (64.9%) eating monkey meat, 127 (55.5%) with eating bats, and 198 (64.9%) with conducting public meetings where there is an Ebola infected person. Out of 142 farmers, 55 (38.7%) believed that Ebola outbreaks affected demand and sale of pigs. The EVD outbreak significantly led to a reduction in the average number of pigs sold (P = 0.001), the average number of pigs bought by traders (P = 0.04), and the number of pigs sold/ slaughtered by butcher men at pork eating places (P = 0.03). CONCLUSION: This study showed that EVD outbreak negatively affected the pig value chain i.e., the demand and supply of pigs and pork. Therefore, there is need to sensitize the stakeholders in the pig value chain on EVD in order to minimize the negative economic impacts associated with EVD outbreaks.

Sporadic outbreaks of crimean-congo haemorrhagic fever in Uganda, July 2018-January 2019.

INTRODUCTION: Crimean-Congo haemorrhagic fever (CCHF) is a tick-borne, zoonotic viral disease that causes haemorrhagic symptoms. Despite having eight confirmed outbreaks between 2013 and 2017, all within Uganda's 'cattle corridor', no targeted tick control programs exist in Uganda to prevent disease. During a seven-month-period from July 2018-January 2019, the Ministry of Health confirmed multiple independent CCHF outbreaks. We investigated to identify risk factors and recommend interventions to prevent future outbreaks. METHODS: We defined a confirmed case as sudden onset of fever (≥37.5°C) with ≥4 of the following signs and symptoms: anorexia, vomiting, diarrhoea, headache, abdominal pain, joint pain, or sudden unexplained bleeding in a resident of the affected districts who tested positive for Crimean-Congo haemorrhagic fever virus (CCHFv) by RT-PCR from 1 July 2018-30 January 2019. We reviewed medical records and performed active case-finding. We conducted a case-control study and compared exposures of case-patients with age-, sex-, and sub-county-matched control-persons (1:4). RESULTS: We identified 14 confirmed cases (64% males) with five deaths (case-fatality rate: 36%) from 11 districts in western and central region. Of these, eight (73%) case-patients resided in Uganda's 'cattle corridor'. One outbreak involved two case-patients and the remainder involved one. All case-patients had fever and 93% had unexplained bleeding. Case-patients were aged 6-36 years, with persons aged 20-44 years more affected (AR: 7.2/1,000,000) than persons ≤19 years (2.0/1,000,000), p = 0.015. Most (93%) case-patients had contact with livestock ≤2 weeks before symptom onset. Twelve (86%) lived <1 km from grazing fields compared with 27 (48%) controls (ORM-H = 18, 95% CI = 3.2-∞) and 10 (71%) of 14 case-patients found ticks attached to their bodies ≤2 weeks before symptom onset, compared to 15 (27%) of 56 control-persons (ORM-H = 9.3, 95%CI = 1.9-46). CONCLUSIONS: CCHF outbreaks occurred sporadically during 2018-2019, both within and outside 'cattle corridor' districts of Uganda. Most cases were associated with tick exposure. The Ministry of Health should partner with the Ministry of Agriculture, Animal Industry and Fisheries to develop joint nationwide tick control programs and strategies with shared responsibilities through a One Health approach.

Low proportion of women who came knowing their HIV status at first antenatal care visit, Uganda, 2012-2016: a descriptive analysis of surveillance data.

BACKGROUND: HIV testing is the cornerstone for HIV care and support services, including Prevention of Mother to Child Transmission of HIV (PMTCT). Knowledge of HIV status is associated with better reproductive health choices and outcomes for the infant's HIV status. We analyzed trends in known current HIV status among pregnant women attending the first antenatal care (ANC) visit in Uganda, 2012-2016. METHODS: We conducted secondary data analysis using District Health Information Software2 data on all pregnant women who came for ANC visit during 2012-2016. Women who brought documented HIV negative test result within the previous 4 weeks at the first ANC visit or an HIV positive test result and/or own HIV care card were considered as knowing their HIV status. We calculated proportions of women with known current HIV status at first ANC visit, and described linear trends both nationally and regionally. We tested statistical significance of the trend using modified Poisson regression with generalized linear models. For known HIV positive status, we only analyzed data for years 2015-2016 because this is when this data became available. RESULTS: There was no significant difference in the number of women that attended first ANC visits over years 2012-2016. The proportion of women that came with known HIV status increased from 4.4% in 2012 to 6.9% in 2016 and this increase was statistically significant (p < 0.001). Most regions had an increase in trend except the West Nile and Mid-Eastern (p < 0.001). The proportion of women that came knowing their HIV positive status at first ANC visit was slightly higher than that of women that were newly tested HIV positive at first ANC visit in 2015 and 2016. CONCLUSION: Although the gap in women that come at first ANC visit without knowing their HIV positive status might be reducing, a large proportion of women who were infected with HIV did not know their status before the first ANC visit indicating a major public health gap. We recommend advocacy for early ANC attendance and hence timely HIV testing and innovations to promptly identify HIV positive women of reproductive age so that timely PMTCT interventions can be made.

Multidrug-resistant tuberculosis outbreak associated with poor treatment adherence and delayed treatment: Arua District, Uganda, 2013-2017.

BACKGROUND: In August 2017, the Uganda Ministry of Health was notified of increased cases of multidrug-resistant tuberculosis (MDR-TB) in Arua District, Uganda during 2017. We investigated to identify the scope of the increase and risk factors for infection, evaluate health facilities' capacity to manage MDR-TB, and recommend evidence-based control measures. METHODS: We defined an MDR-TB case-patient as a TB patient attending Arua Regional Referral Hospital (ARRH) during 2013-2017 with a sputum sample yielding Mycobacterium tuberculosis resistant to at least rifampicin and isoniazid, confirmed by an approved drug susceptibility test. We reviewed clinical records from ARRH and compared the number of MDR-TB cases during January-August 2017 with the same months in 2013-2016. To identify risk factors specific for MDR-TB among cases with secondary infection, we conducted a case-control study using persons with drug-susceptible TB matched by sub-county of residence as controls. We observed infection prevention and control practices in health facilities and community, and assessed health facilities' capacity to manage TB. RESULTS: We identified 33 patients with MDR-TB, of whom 30 were secondary TB infection cases. The number of cases during January-August 2017 was 10, compared with 3-4 cases in January-August from 2013 to 2016 (p = 0.02). Men were more affected than women (6.5 vs 1.6/100,000, p < 0.01), as were cases ≥18 years old compared to those < 18 years (8.7 vs 0.21/100,000, p < 0.01). In the case-control study, poor adherence to first-line anti-TB treatment (aOR = 9.2, 95% CI: 2.3-37) and initiating treatment > 15 months from symptom onset (aOR = 11, 95% CI: 1.5-87) were associated with MDR-TB. All ten facilities assessed reported stockouts of TB commodities. All 15 ambulatory MDR-TB patients we observed were not wearing masks given to them to minimize community infection. The MDR-TB ward at ARRH capacity was 4 patients but there were 11 patients. CONCLUSION: The number of cases during January-August in 2017 was significantly higher than during the same months in 2013-2016. Poor adherence to TB drugs and delayed treatment initiation were associated with MDR-TB infection. We recommended strengthening directly-observed treatment strategy, increasing access to treatment services, and increasing the number of beds in the MDR-TB ward at ARRH.

Feasibility study of a targeted self-management intervention for reducing stroke risk factors in a high-risk population in Uganda.

INTRODUCTION: Stroke remains a global concern due to increasing lifespan, patterns of industrialization, adoption of harmful western diets, and an increasing prevalence of risk factors such as hypertension, obesity, and diabetes. We investigated an adopted novel self-management intervention, TargetEd mAnageMent Intervention (TEAM) to reduce modifiable stroke risk factors in Uganda. METHODS: A six-month, uncontrolled, prospective pilot study to establish feasibility, acceptability and preliminary efficacy of TEAM in Ugandans at high risk for stroke was conducted. The primary outcome was change in systolic BP from baseline to 24-week follow-up. Secondary outcomes included change in diastolic BP, serum cholesterol, high and low density lipoprotein (HDL, LDL) and triglycerides. RESULTS: Mean (SD) baseline systolic BP was 162.9 (±25.6) mmHg while mean (SD) baseline diastolic BP was 99.1 (±13.8) mmHg. There was a significant reduction in mean baseline blood pressure of 163/98.8mmHg to blood pressure of 147.8/88.0mmHg at 24weeks, P=0.023. There were also significant reductions in the serum total cholesterol levels at 24weeks with P=0.001. CONCLUSION: Targeted training in self-management (TEAM) adapted to the Ugandan setting is feasible, highly acceptable to participants and appears to be associated with reduced blood pressure, improved lipid profiles and improved glucose control in diabetics.
