Prevalence of neuropsychiatric adverse events and associated factors among adult patients on dolutegravir attending Mulago ISS clinic.

INTRODUCTION: Dolutegravir (DTG) is a second-generation integrase strand transfer inhibitor that is recommended by the World Health Organization as the preferred first-line and second-line antiretroviral therapy (ART) in patients with HIV. In 2018, Uganda started using DTG-based regimens as the preferred first-line ART. However, concerns regarding the potential neurotoxicity of DTG have been increasing. Data on the occurrence of neuropsychiatric adverse events (NPAEs) and the associated factors among adult patients who are initiated on or switched to DTG-based first-line or second-line ART in Uganda are limited. OBJECTIVE: This study aimed to determine the prevalence of NPAEs among adult patients on DTG and the factors associated with their occurrence. METHODS: We conducted a cross-sectional study using questionnaires administered by a trained research assistant between 15 November 2021 and 15 December 2021. The study included patients aged ≥18 years with HIV who were either initiated on or switched to a DTG-based ART regimen between 1 January 2018 and 31 October 2021. Informed consent and data were collected from 892 participants attending Mulago ISS clinic, including data on age, sex, marital status, disclosure status, current regimen, duration on ART, concurrent illness, concurrent medications, year of switch to DTG, duration on DTG, whether the onset of NPAEs was immediate or delayed, history of alcohol use or smoking, level of education, report of NPAEs while on DTG, and history of NPAEs while on previous regimen. Data were entered into Epidata version 4.6.0.2 then exported to Stata version 14 for analysis. RESULTS: Of the 892 adults on DTG attending Mulago ISS clinic, 41.7% (95% confidence interval [CI] 38.5%-44.9%) experienced at least one NPAE. DTG duration in years (adjusted prevalence [aPR] = 1.21, p = 0.024), disclosure status (aPR = 1.40, p = 0.042), concurrent medications (aPR = 1.31, p = 0.026), year of switch to DTG, and concurrent illness were associated with an increased occurrence of NPAEs. CONCLUSIONS: The prevalence of NPAEs was higher than that reported by any clinical trial. About 9.1% of participants had experienced severe to life-threatening NPAEs that required intervention from a healthcare professional to improve tolerability. The high prevalence requires that clinicians screen for NPAEs at very visit and reassure patients to maximize the benefits of long-term ART.

Tracheostomy-related indications, early complications and their predictors among patients in low resource settings: a prospective cohort study in the pre-COVID-19 era.

BACKGROUND: Tracheostomy is a life-saving procedure whose outcomes may vary between hospitals based on disparities in their existing expertise. We aimed at establishing the indications, early tracheostomy-related complications and their associated factors in Uganda. METHODS: In a prospective cohort study, we consecutively enrolled one-hundred patients, both adults and children 2 h post-tracheostomy procedure. At baseline, information on patients' socio-demographics, tracheostomy indications, pre- and post-procedural characteristics was collected through researcher administered questionnaires and from medical records. Clinical examination was performed at baseline but also at either day 7 or whenever a tracheostomy-related complication was suspected during the 7 days follow-up. Comparison of patients' baseline characteristics, tracheostomy indications and complications across two hospitals was done using Pearson's chi-square. For predictors of early tracheostomy complications, bivariate and multivariate analysis models were fitted using binomial regression in STATA 13.0 software. RESULTS: All patients underwent surgical tracheostomy. Majority were adults (84%) and males (70%). The commonest tracheostomy indications were; pulmonary toilet (58%) and anticipated prolonged intubation (42%). Overall, 53% (95% CI: 43.0 - 62.7) had early complications with the commonest being tube obstruction (52.6%). Independent predictors of early tracheostomy-related complications were; anticipated prolonged intubation as an indication (RR = 1.8, 95%CI: 1.19 - 2.76), Bjork flap tracheal incision (RR = 1.6, 95%CI: 1.09 - 2.43), vertical tracheal incision (RR = 1.53, 95%CI: 1.02 - 2.27), and age below 18 years (RR = 1.22, 95%CI: 1.00 - 1.47). CONCLUSION: Pulmonary toilet is the commonest tracheostomy indication at major hospitals in Uganda. The incidence of early tracheostomy complications is high and majorly related to post-procedure tracheostomy tube management. Having anticipated prolonged intubation as an indication for tracheostomy, a Bjork flap or vertical tracheal incisions and being a child were associated with increased risk of complications. Emphasis on multidisciplinary team care, standardization of tracheostomy care protocols, and continuous collection of patient data as well as paying attention to patient quality of life factors such as early return to oral feeding, ambulation and normal speech may have great potential for improved quality of tracheostomy care in low resource settings.

The risk of hyperglycemia associated with use of dolutegravir among adults living with HIV in Kampala, Uganda: A case-control study.

Emerging evidence suggests a possible association between hyperglycemia and dolutegravir (DTG), a preferred first-line antiretroviral agent in sub-Saharan Africa (SSA). There is need for rigorous studies to validate this association in the face of increasing DTG use and burden of non-communicable diseases among people living with HIV (PLHIV). We conducted a case-control study to assess the risk of hyperglycemia associated with use of DTG among PLHIV attending Mulago ISS Clinic in Kampala. Cases had hyperglycemia while controls had no hyperglycemia as confirmed by fasting plasma glucose and oral glucose tolerance tests. Demographic, laboratory, and clinical data were collected using interviewer-administered questionnaires and medical record abstraction. Analysis compared cases and controls on DTG use prior to diagnosis of hyperglycemia while controlling for potential confounders using multivariable logistic regression. We included 204 cases and 231 controls. In multivariable analysis, patients with prior DTG use had seven times greater odds of subsequent diagnosis of hyperglycemia compared to those who had non-DTG-based regimens (adjusted odds ratio [aOR] 7.01, 95% CI 1.96-25.09). The odds of hyperglycemia also increased with age (56 years and above vs. 18-35, aOR 12.38, 95% CI 3.79-40.50) and hypertension (aOR 5.78, 95% CI 2.53-13.21). Our study demonstrates a strong association between prior DTG exposure and subsequent diagnosis of hyperglycemia. Given the benefits of DTG, wide-scale use, and the growing burden of diabetes mellitus (DM) in SSA, there is need for systematic screening for hyperglycemia and consideration of alternate regimens for those at risk for DM.

Prevalence and factors associated with depressive illness in patients with tuberculosis in Mulago hospital, Kampala- Uganda: A cross sectional study.

BACKGROUND: Depression is a major cause of the global disease burden and globally affects 350-400 million persons making it the largest contributor to years lived with disability. Among of patients with chronic physical illnesses like tuberculosis, depression affects up to 25-33% of individuals. There are limited studies on the comorbidity of depressive illness and tuberculosis in the Ugandan setting. Our aim was to determine the prevalence and factors associated with depressive illness in patients with tuberculosis in Mulago Hospital, Uganda. METHODS: This was a cross sectional study involving 308 consecutively sampled participants aged 18 years and above diagnosed with tuberculosis attending the tuberculosis clinic in Mulago Hospital, Uganda. Consecutive sampling was done for a sample size of 308 participants. Participants had the following instruments administered to them; the Socio-demographic questionnaire, the Mini Neuropsychiatric Interview (MINI) to diagnose depressive illness and the Patient Health Questionnaire- 9 to rate the severity of depression. Data was entered using Epi-Data. Descriptive, bivariate and multivariate analyses were done with the Statistical Package for Social Sciences (SPSS). RESULTS: the prevalence of depressive illness was 23.7% (95% confidence interval 19.3-28.9). Depressive illness was independently associated with low education level (AOR = 0.39, 95%CI = 0.21-0.72, p = 0.003), being in the intensive phase of TB treatment (AOR = 2.34, 95%CI = (1.27-4.33), p = 0.007) and family history of depressive illness (AOR = 5.42, 95%CI = 2.02-14.54, p = 0.001). On the PHQ, 60.3% had moderate to severe depression. CONCLUSION: Depressive illnesses should be screened and managed among patients with TB. RECOMMENDATION: Depression should be routinely screened and managed among patients with Tuberculosis.
