RESUMO
BACKGROUND: Diabetes mellitus (DM) has a direct impact on the clinical manifestation and prognosis of active tuberculosis disease (TB) and is known to increase the chance of developing the condition. We sought to determine the prevalence of DM in adult Ugandan patients with recently diagnosed TB and the associated sociodemographic, anthropometric, and metabolic characteristics of TB-DM comorbidity. METHODS: In this cross-sectional study conducted at the adult TB treatment centres of three tertiary healthcare facilities in Uganda, we screened adult participants with recently diagnosed TB (diagnosed in < 2 months) for DM. All participants were screened with five tests; initially with a random blood glucose (RBG) test, and then later with fasting blood glucose (FBG), laboratory-based glycated hemoglobin (HbA1c), point-of-care (POC) HbA1c, and oral glucose tolerance test (OGTT) if the RBG was ≥ 6.1 mmol/l. The WHO guidelines for diagnosing and managing DM were used to support the DM diagnosis. To identify the factors associated with DM-TB comorbidity, logistic regression was used. RESULTS: A total of 232 participants with recently diagnosed TB were screened for DM. Of these, 160 (69%) were female. The median (IQR) age, body mass index, and RBG of all study participants was 35 (27-42) years, 19.2 (17.6-21.3) kg/m2, and 6.1 (5.5-7.2) mmol/l, respectively. About half of the participants (n = 117, 50.4%) had RBG level ≥ 6.1 mmol/l. Of these, 75 (64.1%) participants returned for re-testing. Diabetes mellitus was diagnosed in 32 participants, corresponding to a prevalence of 13.8% (95% CI 9.9-18.9). A new diagnosis of DM was noted in 29 (90.6%) participants. On logistic regression, age ≥ 40 years was associated with increased odds of TB and DM comorbidity (AOR 3.12, 95% CI 1.35-7.23, p = 0.008) while HIV coinfection was protective (AOR 0.27, 95% CI 0.10-0.74, p = 0.01). CONCLUSION: TB and DM comorbidity was relatively common in this study population. Routine screening for DM in adult Ugandan patients with recently diagnosed TB especially among those aged ≥ 40 years and HIV-negative patients should be encouraged in clinical practice.

BACKGROUND: Active tuberculosis (TB) significantly increases the risk of cardiovascular disease, but the underlying mechanisms remain unclear. This study aimed to investigate the association between inflammation biomarkers and dyslipidemia in patients with drug-resistant TB (DR-TB). METHODS: This was a secondary analysis of data from a cross-sectional multi-center study in Uganda conducted 2021. Participants underwent anthropometric measurements and laboratory tests included a lipid profile, full haemogram and serology for HIV infection. Dyslipidemia was defined as total cholesterol > 5.0 mmol/l and/or low-density lipoprotein cholesterol > 4.14 mmol/l, and/or triglycerides (TG) ≥ 1.7 mmol/l, and/or high density lipoprotein cholesterol (HDL-c) < 1.03 mmol/l for men and < 1.29 mmol/l for women. Biomarkers of inflammation were leukocyte, neutrophil, lymphocyte, monocyte, and platelet counts, as well as neutrophil/lymphocyte (NLR), platelet/lymphocyte, and lymphocyte/monocyte (LMR) ratios, mean corpuscular volume (MCV), and the systemic immune inflammation index (SII) (neutrophil × platelet/lymphocyte). Modified Poisson Regression analysis was used for determining the association of the biomarkers and dyslipidemia. RESULTS: Of 171 participants, 118 (69.0%) were co-infected with HIV. The prevalence of dyslipidemia was 70.2% (120/171) with low HDL-c (40.4%, 69/171) and hypertriglyceridemia (22.5%, 38/169) being the most common components. Patients with dyslipidemia had significantly higher lymphocyte (P = 0.008), monocyte (P < 0.001), and platelet counts (P = 0.014) in addition to a lower MCV (P < 0.001) than those without dyslipidemia. Further, patients with dyslipidemia had lower leucocyte (P < 0.001) and neutrophil (P = 0.001) counts, NLR (P = 0.008), LMR (P = 0.006), and SII (P = 0.049). The MCV was inversely associated with low HDL-C (adjusted prevalence ratio (aPR) = 0.97, 95% CI 0.94-0.99, P = 0.023) but was positively associated with hypertriglyceridemia (aPR = 1.04, 95% CI 1.00-1.08, P = 0.052). CONCLUSIONS: Individuals with dyslipidemia exhibited elevated lymphocyte, monocyte, and platelet counts compared to those without. However, only MCV demonstrated an independent association with specific components of dyslipidemia. There is need for further scientific inquiry into the potential impact of dyslipidemia on red cell morphology and a pro-thrombotic state among patients with TB.

Coronavirus disease-2019 (COVID-19) is the leading cause of death worldwide from a single infectious agent. Whether or not HIV infection affects clinical outcomes in patients with COVID-19 remains inconclusive. This study aimed to compare the clinical outcomes of people living with HIV (PLWH) and non-HIV-infected patients hospitalized during the second wave of the COVID-19 pandemic in Uganda. We retrospectively retrieved data on patients with COVID-19 who were admitted to the Mulago National Referral Hospital in Uganda between April 2021 and mid-July 2021. We performed propensity-score-matching of 1:5 to compare outcomes in COVID-19 patients living with and those without HIV coinfection (controls). We included 31 PLWH and 155 non-HIV controls. The baseline characteristics were similar across groups (all p values > 0.05). PLWH had close to threefold higher odds of having ICU consultation compared to controls (odds ratio [OR]: 2.9, 95% CI: 1.2-6.9, p = 0.015). There was a trend toward having a severe or critical COVID-19 illness among PLWHIH compared to controls (OR: 1.9, 95% CI: 0.8-4.7, p = 0.164). Length of hospitalization was not significantly different between PLWH and non-HIV controls (6 days vs. 7 days, p = 0.184). Seven-day survival was 63% (95% CI: 42%-78%) among PLWH and 72% (95% CI: 61%-82%) among controls while 14-day survival was 50% (95% CI: 28%-69%) among PLWH and 65% (95% CI: 55%-73%) among controls (p = 0.280). There was another trend toward having 1.7-fold higher odds of mortality among PLWH compared to controls (OR: 1.7, 95% CI: 0.8-3.8, p = 0.181). Our data suggest that PLWH may be at an increased risk of severe or critical COVID-19 illness requiring ICU consultation. Further studies with larger sample sizes are recommended.

OBJECTIVE: To investigate the current status of the availability and affordability of specific essential medicines and diagnostics for diabetes in Africa. METHODS: Systematic review and meta-analysis. Studies conducted in Africa that reported any information on the availability and affordability of short-acting, intermediate-acting, and premixed insulin, glibenclamide, metformin, blood glucose, glycated haemoglobin or HbA1c, and lipid profile tests were included. Random-effect model meta-analysis and descriptive statistics were performed to determine the pooled availability and affordability, respectively. RESULTS: A total of 21 studies were included. The pooled availability of each drug was as follows: short-acting insulin 33.5% (95% CI: 17.8%-49.2%, I2 = 95.02%), intermediate-acting insulin 23.1% (95% CI: 6.3%-39.9%, I2 = 91.6%), premixed insulin 49.4% (95% CI: 24.9%-73.9%, I2 = 90.57%), glibenclamide 55.9% (95% CI: 43.8%-68.0%, I2 = 96.7%), and metformin 47.0% (95% CI: 34.6%-59.4%, I2 = 97.54%). Regarding diagnostic tests, for glucometers the pooled availability was 49.5% (95% CI: 37.9%-61.1%, I2 = 97.43%), for HbA1c 24.6% (95% CI: 3.1%-46.1%, I2 = 91.64), and for lipid profile tests 35.7% (95% CI: 19.4%-51.9%, I2 = 83.77%). The median (IQR) affordability in days' wages was 7 (4.7-7.5) for short-acting insulin, 4.4 (3.9-4.9) for intermediate-acting insulin, 7.1 (5.8-16.7) for premixed insulin, 0.7 (0.7-0.7) for glibenclamide, and 2.1 (1.8-2.8) for metformin. CONCLUSION: The availability of the five essential medicines and three diagnostic tests for diabetes in Africa is suboptimal. The relatively high cost of insulin, HbA1c, and lipid profile tests is a significant barrier to optimal diabetes care. Pragmatic country-specific strategies are urgently needed to address these inequities in access and cost.

Vulvovaginal candidiasis (VVC) is a commonly occurring form of mucocutaneous candidiasis in women. The aim of this study was to comprehensively investigate the prevalence, antifungal susceptibility, and etiology of VVC in sub-Saharan Africa (SSA). A search of studies was conducted in seven online databases and the reference lists of selected studies. Observational studies published between January 2000, to July 2021, that met the eligibility criteria were included. Meta-analyses with random and fixed-effects model, and subgroup analyses were performed using STATA 16.0. A total of 41 studies including 15 723 participants were included in the meta-analyses. The pooled prevalence of VVC was 33% (95% Confidence Interval (CI): 28-38%, I2 = 98%, P < 0.001). Pregnant women had 6% higher odds of having VVC compared to non-pregnant women Odds Ratio (OR): 1.06, 95% CI: 0.99-1.13, P = 0.107). The odds of diagnosing VVC were 40% higher in symptomatic patients than general study population (OR: 1.4, 95% CI: 1.3-1.5, P < 0.0001). In 17 studies, a total of 2112 isolates of Candida species were reported: 1514 (71.7%) Candida albicans, 510 (24.1%) non-albicans Candida (NAC) species and 88 (4.2%) unidentified Candida spp. Of the NAC species detected, Candida glabrata (40.9%, n = 209), Candida krusei (21.2%, n = 108), and Candida tropicalis (22.7%, n = 116) were the most common. Resistance to fluconazole in Candida albicans using disc diffusion methods ranged from 6.8% in Cameroon to 53.7% in Ethiopia. One-third of women in SSA have VVC, mainly caused by C. albicans. Data on the susceptibility of the Candida isolates to commonly used antifungal agents is limited and warrants further research. LAY SUMMARY: The overarching aim of this study was to comprehensively investigate the prevalence, antifungal susceptibility, and causative species of vulvovaginal candidiasis (VVC) in sub-Saharan Africa (SSA). A detailed search of studies was conducted to retrieve eligible observational studies published 'between' January 1, 2000, to July 31, 2021. From the 41 selected studies including 15 723 participants, VVC was found in 33% of the participants. The chances of diagnosing VVC was 40% higher in symptomatic patients compared to the general study population. In 71.7% of the cases, C. albicans was the causative species of VVC. We conclude that about one-third of women in SSA have VVC, mainly caused by C. albicans.

Anaemia predicts delayed sputum conversion and mortality in tuberculosis (TB). We determined the prevalence and factors associated with anaemia among people with TB at the National Tuberculosis Treatment Centre in Uganda. People with bacteriologically confirmed TB were consecutively enrolled in a cross-sectional study between August 2017 and March 2018. Blood samples were tested for a full blood hemogram, HIV infection, and CD4+ and CD8+ T-cell counts. Anaemia was defined as a haemoglobin level of <13.0 grams per decilitre (g/dl) for males and <12.0 g/dl for females. Of 358 participants, 210 (58.7%, 95% confidence interval (CI) 53.4-63.8) had anaemia. Anaemia was associated with night sweats, a longer duration of fever, low body mass index (BMI), hyperthermia, high sputum bacillary loads, HIV co-infection, and low CD4 and CD8 counts at bivariate analysis. Factors associated with anaemia at multivariable analysis were low BMI (odds ratio (OR) 2.93, 95% CI 1.70-5.05, P < 0.001), low CD4:CD8 ratio (OR 2.54, 95% CI 1.07-6.04, P = 0.035) and microcytosis (OR 4.23, 95% CI 2.17-8.25, P < 0.001). Anaemia may be associated with the features of severe TB disease and should be considered in TB severity scores.

BACKGROUND: Tuberculosis (TB) and its risk factors are independently associated with cardiovascular disease (CVD). We determined the prevalence and associations of CVD risk factors among people with drug-resistant tuberculosis (DRTB) in Uganda. METHODS: In this cross-sectional study, we enrolled people with microbiologically confirmed DRTB at four treatment sites in Uganda between July to December 2021. The studied CVD risk factors were any history of cigarette smoking, diabetes mellitus (DM) hypertension, high body mass index (BMI), central obesity and dyslipidaemia. We used modified Poisson regression models with robust standard errors to determine factors independently associated with each of dyslipidaemia, hypertension, and central obesity. RESULTS: Among 212 participants, 118 (55.7%) had HIV. Overall, 196 (92.5%, 95% confidence interval (CI) 88.0-95.3) had ≥ 1 CVD risk factor. The prevalence; 95% CI of individual CVD risk factors was: dyslipidaemia (62.5%; 55.4-69.1), hypertension (40.6%; 33.8-47.9), central obesity (39.3%; 32.9-46.1), smoking (36.3%; 30.1-43.1), high BMI (8.0%; 5.0-12.8) and DM (6.5%; 3.7-11.1). Dyslipidaemia was associated with an increase in glycated haemoglobin (adjusted prevalence ratio (aPR) 1.14, 95%CI 1.06-1.22). Hypertension was associated with rural residence (aPR 1.89, 95% CI 1.14-3.14) and previous history of smoking (aPR 0.46, 95% CI 0.21-0.98). Central obesity was associated with increasing age (aPR 1.02, 95%CI 1.00-1.03), and elevated diastolic blood pressure (aPR 1.03 95%CI 1.00-1.06). CONCLUSION: There is a high prevalence of CVD risk factors among people with DRTB in Uganda, of which dyslipidaemia is the commonest. We recommend integrated services for identification and management of CVD risk factors in DRTB.

BACKGROUND: Postoperative complications and mortality following laparotomy have remained high worldwide. Early postoperative risk stratification is essential to improve outcomes and clinical care. The surgical Apgar score (SAS) is a simple and objective bedside prediction tool that can guide a surgeon's postoperative decision making. The objective of this study was to evaluate the performance of SAS in predicting outcomes in patients undergoing laparotomy at Mulago hospital. METHOD: A prospective observational study was conducted among eligible adult patients undergoing laparotomy at Mulago hospital and followed up for 4 months. We collected data on the patient's preoperative and intraoperative characteristics. Using the data generated, SAS was calculated, and patients were classified into 3 groups namely: low (8-10), medium (5-7), and high (0-4). Primary outcomes were in-hospital major complications and mortality. Data was presented as proportions or mean (standard deviation) or median (interquartile range) as appropriate. We used inferential statistics to determine the association between the SAS and the primary outcomes while the SAS discriminatory ability was determined from the receiver-operating curve (ROC) analysis. RESULTS: Of the 151 participants recruited, 103 (68.2%) were male and the mean age was 40.6 ± 15. Overall postoperative in-hospital major complications and mortality rates were 24.2% and 10.6%, respectively. The participants with a high SAS category had an18.4 times risk (95% CI, 1.9-177, p = 0.012) of developing major complications, while those in medium SAS category had 3.9 times risk (95% CI, 1.01-15.26, p = 0.048) of dying. SAS had a fair discriminatory ability for in-hospital major complications and mortality with the area under the curve of 0.75 and 0.77, respectively. The sensitivity and specificity of SAS ≤ 6 for major complications were 60.5% and 81.14% respectively, and for death 54.8% and 81.3%, respectively. CONCLUSION: SAS of ≤ 6 is associated with an increased risk of major complications and/or mortality. SAS has a high specificity with an overall fair discriminatory ability of predicting the risk of developing in-hospital major complications and/or death following laparotomy.

Fungal sensitization is associated with poor asthma control. We aimed to determine the prevalence and factors associated with fungal asthma among Ugandan adults. Individuals aged ≥18 years with a new diagnosis of asthma in the last 12 months participating in the African Severe Asthma Program constituted the study population. Skin prick test results, clinical and demographic data were retrieved from the database, and serum Aspergillus fumigatus specific antibodies and total IgE were measured in stored blood. We enrolled 374 patients, median (IQR) age 34 (25-45) years, 286 (76.5%) females and 286 (76.5%) with severe asthma. Prevalence of Aspergillus fumigatus sensitization was 42.0% (95% CI: 37.1-47.0%), allergic bronchopulmonary aspergillosis (ABPA) 3.2% (1.8-5.5%), severe asthma with fungal sensitization (SAFS) 16% (12.7-20.1%) and allergic bronchopulmonary mycosis (ABPM) 2.9% (1.7-5.2%). Older age (55-64 years) (crude odds ratio (cOR) = 2.6), sensitization to at least one allergen (cOR = 9.38) and hypertension (cOR = 1.99) were significantly associated with Aspergillus sensitization, whereas tertiary education level (cOR = 0.29), severe depression (cOR = 0.15) and strong emotions (cOR = 0.47) were not. High occupational exposure to Aspergillus (cOR = 4.26) and contact with moulds (cOR = 14.28) were significantly associated with ABPA. Palpitations (cOR = 5.54), uncontrolled asthma (cOR = 3.54), eczema/dermatitis (cOR = 3.07), poor lung function (cOR = 2.11) and frequent exacerbations (cOR = 1.01) were significantly associated with SAFS. Eczema/dermatitis (cOR = 1.55) was significantly associated with ABPM, but cold weather trigger (cOR = 0.24) was not. Fungal asthma is a significant problem among Ugandans with asthma and should be particularly considered in individuals who remain uncontrolled despite optimal standard of care for asthma, as it is responsive to available and affordable oral antifungal therapy. LAY SUMMARY: This study showed that fungal asthma is a significant problem among Ugandans with asthma with a high prevalence. Fungal asthma should be considered in patients with uncontrolled asthma despite receiving optimal standard of care. This is the first modern attempt to define these endotypes of asthma in Africa.

Chronic pulmonary aspergillosis (CPA) is an emerging fungal infectious disease of public health importance. We conducted a systematic review of studies reporting the outcomes of patients with CPA managed surgically in Africa. A search of Medline, Embase, Web of Science, Google Scholar and African Journals Online was conducted to identify studies indexed from inception to June 2021 that examined surgical management of CPA in Africa. All articles that presented primary data, including case reports and case series, were included. We excluded review articles. A total of 891 cases (557 males (62.5%), mean age 39.3 years) extracted from 27 eligible studies published between 1976 and 2020 from 11 African countries were included. Morocco (524, 59%) and Senegal (99, 11%) contributed the majority of cases. Active or previous pulmonary tuberculosis was reported in 677 (76.0%) cases. Haemoptysis was reported in 682 (76.5%) cases. Lobectomy (either unilateral or bilateral, n = 493, 55.3%), pneumonectomy (n = 154, 17.3%) and segmentectomy (n = 117, 13.1%) were the most frequently performed surgical procedures. Thirty (4.9%) cases from South Africa received bronchial artery embolisation. Empyema (n = 59, 27.4%), significant haemorrhage (n = 38, 173.7%), incomplete lung expansion (n = 26, 12.1%) and prolonged air leak (n = 24, 11.2%) were the most frequent complications. Overall, 45 (5.1%) patients died. The causes of death included respiratory failure (n = 14), bacterial superinfection/sepsis (n = 10), severe haemorrhage (n = 5), cardiopulmonary arrest (n = 3) and complications of chronic obstructive pulmonary disease (n = 3). The cause of death was either unknown or unspecified in 9 cases. We conclude that surgical treatment had very low mortality rates and maybe considered as first-line management option in centres with experience and expertise in Africa.

Tinea capitis is a common and endemic dermatophytosis among school age children in Africa. However, the true burden of the disease is unknown in Africa. We aimed to estimate the burden of tinea capitis among children <18 years of age in Africa. A systematic review was performed using Embase, MEDLINE and the Cochrane Library of Systematic Reviews to identify articles on tinea capitis among children in Africa published between January 1990 and October 2020. The United Nation's Population data (2019) were used to identify the number of children at risk of tinea capitis in each African country. Using the pooled prevalence, the country-specific and total burden of tinea capitis was calculated. Forty studies involving a total of 229,086 children from 17/54 African countries were identified and included in the analysis. The pooled prevalence of tinea capitis was 23% (95% CI, 17%-29%) mostly caused by Trichophyton species. With a population of 600 million (46%) children, the total number of cases of tinea capitis in Africa was estimated at 138.1 (95% CI, 102.0-174.1) million cases. Over 96% (132.6 million) cases occur in sub-Saharan Africa alone. Nigeria and Ethiopia with the highest population of children contributed 16.4% (n = 98.7 million) and 8.5% (n = 52.2 million) of cases, respectively. Majority of the participants were primary school children with a mean age of 10 years. Cases are mostly diagnosed clinically. There was a large discrepancy between the clinical and mycological diagnosis. About one in every five children in Africa has tinea capitis making it one of the most common childhood conditions in the region. A precise quantification of the burden of this neglected tropical disease is required to inform clinical and public health intervention strategies.

BACKGROUND: Dental health is often neglected by the majority of the population and has contributed to the global burden of oral diseases. We assessed awareness, utilization and barriers to seeking oral health care among adults in Nebbi District, Uganda. METHODS: A community-based, cross sectional study was conducted in the central division, Nebbi District in Uganda among adults between the age of 18 years or older. An interviewer-administered, semi-structured questionnaire was used for data collection on socio-demographic characteristics, oral health awareness, oral health utilization, associated factors and barriers. RESULTS: A total of 400 adults with a median age of 32 years (interquartile range 24-43) years were enrolled. More than half (57.5%, n = 230) of the participants were female. Participants identified smoking (42.8%, n = 171) and consumption of sugary foodstuffs (29.0%, n = 116) as risk factors for oral disease. Not brushing was also identified by 260 participants (65.0%) as the cause of tooth decay and 95.8% (n = 383) believed brushing one's teeth could prevent tooth decay. Of the 51.5% (n = 206) who had experienced a toothache or discomfort 12 months prior to the study but only about half (52%, n = 106) had sought healthcare from a dental clinic or facility. About 89.5% (n = 94) of the participants were able to see a dentist during their last visits. Dental carries (76.6%, n = 70) and gum bleeding (14.9%, n = 14) were the most frequent reasons for visiting a dental clinic, and 73.7% (n = 70) had their tooth extracted. Barriers to seeking oral healthcare were cost of treatment (47.5%, n = 190), and long waiting time (18.5%, n = 74). The odds of seeking oral healthcare was 2.8-fold higher in participants who were being married (Odds ratio (OR): 2.8, 95% CI 1.3-6.3, p = 0.011) and 3.5-fold higher among housewives (COR: 3.5, 95% CI 1.1-11.4, p = 0.040). CONCLUSION: About half of the participants had sought healthcare following a dental condition. Cost of treatment seems to be an important factor affecting utilization of oral health services. Optimization of costs, and creating awareness regarding benefits of utilizing preventive dental services are recommended.

Chronic pulmonary aspergillosis (CPA) is a potentially life-threatening debilitating lung disease necessitating long-term oral antifungal treatment. However, development of antifungal-resistant isolates of Aspergillus and major toxicities requiring discontinuation of treatment limits their use. Intravenous (IV) antifungals are an option in this group of patients. We comprehensively evaluate the response rates to IV antifungals in the management of CPA. We searched Medline and Embase databases to select clinical studies providing information about IV amphotericin B or an echinocandin for the treatment of CPA from inception to May 2020. Reviews, single-case reports and case series reporting <10 patients were excluded. We evaluated 12 eligible studies. A total of 380 patients received amphotericin B (n = 143) or an echinocandin (n = 237) and were included in the meta-analysis. In a pooled analysis, overall response to IV antifungals was 61% ((95% confidence interval (CI): 52%-70%; I2 = 73.3%; P < .001), to amphotericin B was 58% (95% CI: 36%-80%; I2 = 86.6%; P < .001) and to echinocandins was 62% (95% CI: 53%-72%; I2 = 63.6%; P < .001). Amphotericin B courses were usually doses at slightly <1 mg/Kg (deoxycholate) or 3 mg/Kg (liposomal) for 2-3 weeks. Micafungin doses varied from 12.5 to 300 mg (frequently, 150 mg) daily for at least 3 weeks, and sometimes much longer. Liposomal amphotericin B was well tolerated, but led to renal function loss in 25% of patients. Adverse events were observed in 5-35.3% of patients receiving echinocandins, none of which was considered major. Intravenous antifungals have a place in the management of CPA. A head-to-head comparison of amphotericin B and echinocandins is lacking, and future studies should look at evaluating short- and longer-term outcomes of these agents.

Background: Diagnosis of childhood tuberculosis (TB) poses several challenges. Therefore, point-based scoring systems and diagnostic algorithms have been developed to improve the diagnostic yields in this population. However, there are no updated systematic reviews of the existing childhood TB scoring systems and algorithms. Hence, we systematically reviewed the diagnostic accuracy of the childhood TB diagnostic scoring systems and algorithms. Methods: We systematically searched PubMed, CINAHL, Embase, Scopus, and Google Scholar databases for relevant articles published until 30 March 2023. QUADAS-2 was used to assess their study quality. Diagnostic accuracy measures (ie, sensitivity, specificity, diagnostic odds ratio, positive and negative likelihood ratios) were pooled using a random-effects model. Results: We included 15 eligible studies, with a total of 7327 study participants aged <15 years, with 10 evaluations of childhood TB diagnostic scoring systems and algorithms. Among these algorithms and scoring systems, only 3 were evaluated more than once. These were the Keith Edwards scoring system with 5 studies (sensitivity, 81.9%; specificity, 81.2%), Kenneth Jones criteria with 3 studies (sensitivity, 80.1%; specificity, 45.7%), and the Ministry of Health-Brazil algorithm with 3 studies (sensitivity, 79.9%; specificity, 73.2%). Conclusions: We recommend using the Keith Edwards scoring system because of its high sensitivity and specificity. Further research is necessary to assess the effectiveness of scoring systems and algorithms in identifying TB in children with HIV and malnutrition.
RESUMO
Key Clinical Message: Antimicrobial resistance (AMR) is a public health challenge. It causes unresponsiveness to treatment with antimicrobials, leads to sepsis, septic shock, and increased hospital mortality. This is compounded by new multidrug resistant organisms. We present and discuss a case of sepsis caused by a rare multi-drug resistant bacterium Raoultella ornithinolytica. Abstract: Antimicrobial resistance is a major public health concern worldwide, associated with nearly 5 million deaths. The highest mortality attributed to AMR is seen in sub-Saharan Africa. Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Streptococcus pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa contribute to most deaths attributed to AMR globally. However, other uncommon microorganisms have been implicated. Few cases of resistant, extended-spectrum beta-lactamase (ESBL) producing Raoultella ornithinolytica have been reported to cause sepsis worldwide. To our knowledge, no case of R. ornithinolytica-induced sepsis has been reported in our settings. We report a case of sepsis due to R. ornithinolytica in an injured young adult. We received a 36-year-old man, a professional banker involved in a road traffic accident 2 h before admission. He sustained a deep degloving wound on the right ankle with exposure of the lateral malleolus and presented with severe pain, and bleeding at the injury site. x-Rays confirmed a comminuted intra-articular distal tibia and fibular fracture. Surgical debridement and external fixation were aseptically done on the same day. Below knee amputation was done on the 7th day post-admission due to extensively injured and infected limb with sepsis. Local pus culture isolated ESBL-positive R. ornithinolytica susceptible only to meropenem, ciprofloxacin, and amikacin. Introducing these antibiotics on the 11th post-admission day averted sepsis and enhanced patient recovery. With the threat of AMR, newly emerging highly resistant microbes should be expected and suspected. Early recognition of sepsis and its focus and precise intervention with antimicrobials guided by specimen culture and susceptibility profile is highly recommended and should be standard practice. It highly reduces morbidity and mortality due to sepsis.
RESUMO
BACKGROUND: Adolescent girls and young women (AGYW) in sub-Saharan Africa face a disproportionately higher HIV/AIDS burden despite the global decline in incidence. Existing interventions often fail to adequately address their unique social, economic, and cultural challenges, limiting access to essential HIV/AIDS services, including HIV testing. Emerging evidence indicates that HIV self-testing, a user-friendly and confidential method, enhances HIV diagnosis and linkage to care by targeting these barriers. This study aims to assess the feasibility, acceptability, and preliminary impact of a peer-delivered, community-health worker (CHW)-facilitated HIV self-testing intervention for AGYW in Northern Uganda. METHODS: This mixed-methods quasi-experimental implementation science study will employ a three-fold approach. Firstly, we will conduct baseline formative qualitative research with 50 AGYW, 50 parents/partners to AGYW, 30 CHWs, 15 community leaders, and the district health office to inform the design of a peer-delivered CHW-facilitated HIV self-testing intervention tailored to AGYW's needs in Northern Uganda. Secondly, we will implement a mixed-methods pilot study to assess the intervention's feasibility and acceptability, involving 415 AGYW, 30 AGYW peer leaders, and 10 CHWs in selected parishes and villages in Omoro district, Northern Uganda. Lastly, we will evaluate the implementation outcomes and preliminary impact of the intervention on HIV self-testing rates and linkage to care by collecting and analyzing quantitative data pre- and post-intervention, laying the groundwork for a future robust randomized controlled trial. DISCUSSION: Our intervention combines CHWs and peer-led strategies to address the unique challenges of AGYW in Northern Uganda, leveraging community resilience and peer influence. Successful completion of this project will provide a scalable model to be evaluated in a randomized trial and replicated in similar contexts. TRIAL REGISTRATION NUMBER: PACTR202404851907736.

RESUMO
Background: Tuberculosis (TB) is one of the leading causes of death from a single infectious agent globally. Stigma associated with TB encompassing self-, anticipated-, and public-stigma has significant negative effects on treatment adherence. In Uganda, limited data exist on the prevalence of stigma and its relationship with sex among patients with TB. We evaluate prevalence of three types of stigma and their relationship with the sex of patients undergoing TB treatment. Methods: This cross-sectional study was conducted between July 2020 to March 2021 at selected TB clinics in Kampala, Uganda. Eligible participants were aged 18-65 with confirmed TB and starting their prescribed treatment. We collected data on socio-demographics and used 13 items to capture the self-, anticipated-, and public-stigma from which we composed the dependent variables. The primary independent variable was sex. We employed multivariable logistic regression analysis to evaluate the association between sex and the three stigma types. Additionally, we considered potential confounders such as age, HIV, and employment status. Statistical significance was defined as p<0.05. Results: In this study we enrolled 144 participants with a mean age of 35.8 years (standard deviation = 12). Half of the participants (50%, n=72) were female, 44% had a secondary education, 37.5% were unemployed, and 32.6% were co-infected with HIV. The prevalence of self-stigma was 71.1%, anticipated stigma was 75.7%, and public stigma was 41.7%. Significant factors were associated with self-stigma were female sex (adjusted odds ratio (AOR): 2.35 95% CI: 1.02-5.74) and unemployment (AOR: 2.95 95% CI: 1.16-8.58). HIV-positive status was significantly associated with anticipated stigma (AOR: 3.58 95% CI: 1.38-11.23). However, none of the variables we evaluated showed a significant association with public stigma. Conclusions: Our study showed a high prevalence of self, anticipated and public stigma among TB patients. Notably, females and unemployed individuals were at a higher risk of self-stigma, while those with HIV/AIDS and TB were more likely to report anticipated stigma. To combat stigma effectively, interventions should be tailored to cater to sex-specific needs and persons living with HIV. Future research should delve further in determinants of TB-related stigma in high-burden settings.
RESUMO
Background: Despite the high frequency of adrenal insufficiency (AI) in patients with tuberculosis or HIV, its diagnosis is often missed or delayed resulting in increased mortality. This systematic review and meta-analysis aimed to document the prevalence, significant clinical features, and predictors of AI in adult patients with tuberculosis or HIV. Methods: We systematically searched databases (Medline, Embase, CINAHL, Cochrane Library, and Africa Journal Online) for published studies on AI in adult patients with tuberculosis or HIV. The pooled prevalence of AI was determined by a random-effect model meta-analysis. A narrative review was used to describe the significant clinical features and predictors of AI in adult patients with tuberculosis or HIV. Results: A total of 46 studies involving 4044 adults were included: 1599 with tuberculosis and 2445 with HIV. The pooled prevalence of AI was 33% (95% CI, 22%-45%; I2 = 97.7%, P < .001) in participants with tuberculosis and 28% (95% CI, 18%-38%; I2 = 98.9%, P < .001) in those with HIV. Presentation with multidrug-resistant tuberculosis, abdominal pain, salt craving, myalgia, increased severity and duration of tuberculosis disease, and the absence of nausea predicted AI in participants with tuberculosis in 4 studies. Cytomegalovirus antigenemia positivity, rifampicin therapy, and eosinophilia >3% predicted AI in participants with HIV in 2 studies. Conclusions: AI is relatively common in adults with tuberculosis or HIV. Its timely screening, diagnosis, and management in patients with these 2 conditions should be encouraged to avert mortality.
RESUMO
Background: Intensive glycaemic control reduces the risk of microvascular complications in persons with diabetes mellitus (DM). Owing to limited data available, we aimed to determine the knowledge, attitude, and practices (KAPs) toward glycaemic control among Ugandans with DM at two large tertiary healthcare facilities. Methods: A cross-sectional study was conducted among persons with DM attending outpatient clinics at Kiruddu National Referral Hospital (KNRH) and Mulago National Specialized Hospital (MNSH) between March and April 2022. Eligible participants provided written informed consent and were recruited through a systematic sampling technique and relevant data was collected using a pretested, interviewer-administered, semi-structured questionnaire. Results: Of the 452 participants, 318 (70.4%) were females. The median age was 52 years (IQR: 45-60 years), with more than two-thirds diagnosed with DM at ≥36 years (69.8%, n=310). Overall, 274 participants (60.6%) had good knowledge on glycemic control. At multivariable logistic regression analysis, good knowledge about glycaemic control was significantly associated with having received training on glycaemic control (aOR: 2.3, 95% CI: 1.4 - 3.7, p=0.002), level of education: diploma (aOR: 4.3, 95% CI: 1.1 - 17.8, p=0.042), degree aOR: 4.9, 95% CI: 1.0 - 23.1, p=0.046) compared to informal education, and nearest distance from the health facility (aOR: 3.1, 95% CI: 1.0 - 9.6, p=0.047). Conclusions: More than half of the patients had good knowledge about glycaemic control and this was associated with level of education, distance from the health facility and having received training. Further studies assessing the correlations between actual level of glycaemic control and patient related KAPs are recommended.

Background: Emerging infectious diseases like the Ebola Virus Disease (EVD) pose significant global public health threats. Uganda has experienced multiple EVD outbreaks, the latest occurring in 2022. Frontline healthcare workers (HCWs) are at increased risk, yet there isn't sufficient evidence of existing knowledge of EVD of these health workers. We aimed to assess the readiness of Uganda's emergency healthcare workers to manage Ebola virus disease (EVD) and identify their training needs to inform targeted capacity-building interventions for future outbreaks. Methods: This multicentre nationwide cross-sectional study was conducted from July to August 2023 among 691 HCWs providing emergency care in 14 secondary and tertiary hospitals across Uganda. Participants were consecutively recruited using the probability-proportional-to-size sampling technique, and data was collected using a self-reported questionnaire. Factors associated with EVD knowledge were identified through a mixed-effect linear model. Results: Data from 691 eligible HCWs with a median age of 32 (IQR: 28-38) was analyzed (response rate: 92%). Only one-third (34.4%, n = 238) had received EVD training in the past year. The median EVD knowledge score was 77.4% (IQR: 71.2% - 83.4%). EVD knowledge was associated with longer professional experience in years (ß: 0.21, 95% CI: 0.03 to 0.39, p = 0.024) and higher level of education: diploma (ß: 3.37, 95% CI: 1.49 to 5.25, p < 0.001), undergraduate degree (ß: 6.45, 95% CI: 4.11 to 8.79) and postgraduate degree (ß: 7.13, 95% CI: 4.01 to 10.25, p < 0.001). Being a doctor (ß: 2.55, 95% CI: 0.35 to 4.74, p = 0.023), providing care in the obstetrics/gynecology department (ß: -1.90, 95% CI: -3.47 to - 0.32, p = 0.018), previous EVD training (ß: 2.27, 95% CI: 0.96 to 3.59, p = 0.001) and accessing EVD information through social media (ß: 2.52, 95% CI: 1.17 to 3.88, p < 0.001) were also significantly associated with EVD knowledge. Conclusion: Our study reveals that Ugandan HCWs' EVD response readiness varies by individual factors and information sources. We recommend targeted training and suggest future research on educational innovations and social media's potential to fill knowledge gaps.
