[Interventional study on Dolutegravir and other antiretrovirals in patients with subclinical atherosclerosis in the Kinshasa Hospital]. / Étude interventionnelle sur le dolutégravir et les autres antirétroviraux dans l'athérosclérosclérose infra-clinique en milieu hospitalier de Kinshasa.

Introduction: After 2016, the World Health Organization (WHO) proposed Dolutegravir (DTG) as an alternative first-line treatment for adults. Thus, the purpose of this study was to identify biomarkers of cardiometabolic risk capable of demonstrating the beneficial effect of Dolutegravir (DTG) compared to other antiretrovirals in predicting atherosclerosis in people living with HIV (PLHIV) and hospitalized in Kinshasa Hospital. Methods: we conducted an interventional study of people living with HIV who had received antiretroviral therapy (ART) for at least 6 months and were treated in the structures of the network coordinated by the Catholic Church (BDOM-Bureau Diocésain des Oeuvres Médicales) and of the University Clinics of Kinshasa (CUK) between January 2017 and December 2021. Subclinical atherosclerosis was defined as Pulsed Pressure (PP) ≥60 mm Hg; Carotid Intima-Media Thickness (CIMT) > 0.8 mm; and Systolic Pressure Index (SPI) < 0.9. Logistic regression was used in the statistical analysis of associations. Results: a total of 334 PLHIV were recruited, of whom 96.1% (n=321) were on ART and 13.9% (n=13) were ART naïve patients. The mean age of PLHIV was 51±12 years with a female predominance (70.4%; n=235); the independent determinants of subclinical atherosclerosis were marital status (aOR: 4. 95% CI 1.5-10.5; p<0.006), low socioeconomic level (aOR: 10.7, 95% CI 2.3-48.7 p<0.002), duration of HIV infection (aOR: 6.6, 95% CI 2.8-16; p<0.0001), duration of antiretroviral therapy ≥9 years (aOR: 0.3, 95% CI 0.2-0.7; p<0.005) and total cholesterol ratio/high-density lipoprotein-cholesterol (CT/HDL-c)(aOR: 2, 95% CI 1.1-3.6; p= 0.034). The mean values of traditional and emergent variables were significantly higher in the previous ART regimen without DTG than in the new regimen with DTG. However, dyslipidemia was detected during the new DTG-based regimen. Conclusion: dyslipidemia was common during the DTG-based regimen. Marital status, low socioeconomic level, duration of HIV infection, duration of antiretroviral treatment beyond 9 years and the TC/HDL-c ratio were identified as determinants of subclinical atherosclerosis in PLHIV on ART hospitalized in the Kinshasa hospital.

[Lesions on CT scan in patients hospitalized for coronavirus pneumonia during the first wave of the SARS-CoV-2 pandemic at the University Clinics in Kinshasa (DRC)]. / Lésions tomodensitométriques chez les patients hospitalisés pour pneumonie à COVID-19 lors de la première vague de la pandémie à SARS-CoV-2 aux Cliniques Universitaires de Kinshasa (RDC).

INTRODUCTION: the main purpose of this study is to describe chest computed tomography (CT) findings in 26 patients hospitalized with COVID-19 pneumonia during the first wave of the SARS-CoV-2 pandemic at the University Clinics in Kinshasa (UCK). METHODS: we conducted a descriptive study of chest CT findings in 26 patients hospitalized with coronavirus pneumonia at the UCK over a 9-month period, from March 17 to November 17, 2020. Hitachi - CT-scanner 16 slice was used in all our patients. After analyzing lesions, these were divided into lesions suggestive and non-suggestive of SARS-CoV-2 infection. RESULTS: the average age of patients was 53.02 years. Male sex was the most affected (76.9%). Respiratory distress was the most common clinical symptom (61.5%). Arterial hypertension and renal failure were the most common comorbidities (3O% and 6%). Bilateral ground-glass opacities, with a predominantly peripheral distribution, accounted for 69.2% of cases, followed by condensations (57.7%) and crazy paving (19.2%). Severe COVID-19 was most frequently found (34.61%). Distal and proximal pulmonary embolism was the most common complication (11.5%). Among the associated diseases, pleurisy and pulmonary PAH were most frequently found (30.8%). The majority of our patients had parenchymal lung lesions, corresponding to early-stage disease on CT (50%). CONCLUSION: at the UCK, during the first wave of SARS-CoV-2 pandemic, lesions on CT suggestive of COVID-19 were dominated by plaque-like ground-glass opacities, followed by nonsystematized parenchymatous condensations and crazy paving. The less observed atypical lesions consisted of unilateral, peribronchovascular pseudo-nodular condensations and infection in the remodeled lung. Severe COVID-19 was the most common CT finding. Proximal and distal pulmonary embolism was the most common complication. This study highlights that these findings are consistent with those reported in the literature.

Epidemiological, clinical Characteristics and mortality of patients Infected with SARS-CoV-2 Admitted of Kinshasa University Hospital, Democratic Republic of the Congo from March 24, 2020 to January 30, 2021: Two waves, two faces?

BackgroundThe objective of our retrospective study was to establish a comparison between the first and the second waves of demographic and clinical characteristics as well as mortality and its determinants. MethodsA total of 411 COVID-19 patients were enrolled in Kinshasa University Hospital and categorized into two groups according to the pandemic pattern, demographics, and disease severity. The clinical characteristics were compared according to the two waves. To describe survival from the first day of hospitalization until death, we used Kaplan Meiers method. We used the Log Rank test to compare the survival curves between the two waves. The Cox regression was used to identify independent predictors of mortality. ResultsDuring the study period, 411 patients with confirmed COVID-19 were admitted to the hospital. The average age of patients in the 2nd wave was higher than in the first wave (52.4 {+/-}17.5 vs 58.1 {+/-}15.7, p=0.026). The mean saturation was lower in the first wave than in the second. The death rate of patients in the first wave was higher than in the second wave (p=0.009). Survival was reduced in the first wave compared to the second wave. In the first wave, age over 60 years, respiratory distress, law oxygen saturation ([≤]89%) and severe stage of COVID-19 emerged as factors associated with death, while in the second wave it was mainly respiratory distress, law oxygen saturation ([≤] 89%) and severe stage. The predictors of mortality present in both the first and second waves were respiratory distress and severe COVID-19 stage. ConclusionMortality decreased in the second wave. Age no longer emerged as a factor in mortality in the second wave. Health system strengthening and outreach to those at high risk of mortality should continue to maintain and improve gains.

[Prevalence and determinants of microalbuminuria and macroalbuminuria in children and young adults with type 1 diabetes in Kinshasa]. / Prévalence et déterminants de la microalbuminurie et de la macroalbuminurie chez les enfants et jeunes adultes diabétiques de type 1 à Kinshasa.

AIM: To determine the prevalence and determinants of microalbuminuria and macroalbuminuria in type 1 Congolese diabetics aged less than 30 years. METHODS: Cross sectional study (june-july 2008) at the Primary Health Care Center Boyambi in Kinshasa, The Democratic Republic of the Congo. HbA(1c) and urine albumin excretion (UAE) were measured by an enzyme immunoassay method. Determinants of microalbuminuria and macroalbuminuria were assessed by logistic regression. RESULTS: One hundred and eighty-one type 1 diabetics (female gender: 61.3%) were included in this study. They were aged 19.1+/-5.8 years and were diabetics for 57.6+/-45.1 months. HbA(1c) was superior or equal to 10% in 88%, between 7 and 10% in 4% and inferior to 7% in 8%. Prevalence of microalbuminuria and macroalbuminuria was 21.9% and 7.3%, respectively. Diabetes duration superior to 5 years (OR: 4.1; 95% CI [1.9-8.4]), age superior to 18 years (OR: 2.9 [1.3-6.2]) and HbA(1c) superior to 10% (OR: 2.6 [1.1-6.4]) were independent determinants of pathological UAE. CONCLUSION: Microalbuminuria and even macroalbuminuria are very frequent in type 1 Congolese diabetics aged above or equal to 30 years, especially in those aged above 18 years and diabetics for more than 5 years. Improving diabetes control and treating microalbuminuria is urgently needed to prevent renal insufficiency among children and young adults with type 1 diabetes of The Democratic Republic of the Congo.
