Clinical characteristics of children with autism spectrum disorders: a cross-sectional study of cases attended at three centers specializing in neurodevelopmental disorders in Kinshasa, Democratic Republic of Congo (DRC)

Context and objective. Autism spectrum disorders (ASD) in sub-Saharan African (SSA) countries are poorly studied. The aim of the present study was to describe the socio demographic and clinical characteristics of children with autism and to identify associated factors. Methods. This was a cross-sectional study of children with ASD attended at three specialized centers in Kinshasa. We confirmed a ASD diagnosis through clinical observation using Diagnostic and Statistical Manuel of Mental Disorders four Text Revision (DSM-VI-TR) criteria and standardized autism diagnostic tools. We analyzed socio-demographic and clinical characteristics and main comorbidities of ASD. The comparison of proportions was done using Pearson's chi-square test. One-way ANOVAs were calculated to test differences in averages. Results. A total of 120 children (72.5 % male) were examined. Their mean age at diagnosis was 7.83 ± 3.4 years, while parents were alerted at 1.8 ±0.78 years. Language delays were the main alert sign (54%) and the main symptom (62%). Social interaction disorders (11.7 %) were underreported by parents. The core signs of ASD were disorders of social interaction (90.5%), behavior (80%) and language (62.5%). The main ASD symptoms were associated with epilepsy(p=0.027), cerebral palsy (p=0.026) and hearing impairment (p=0.045). Conclusion. The diagnostic and language delay co-occurring with epilepsy and hearing impairment are the main clinical features of autism in the DRC. This study suggests that screening children for autism and its main comorbidities using a multidisciplinary approach should be a priority in Kinshasa.

Stress, anxiété, dépression et qualité de vie des patients tuberculeux pharmacorésistants à Kinshasa, République Démocratique du Congo / Stress, anxiety, depression and quality of life of drug-resistant tuberculosis patients in Kinshasa, Democratic Republic of the Congo

Contexte & objectif. La prise en charge médicale de la tuberculose pharmacorésistante connaît des progrès dans le monde. Mais, le volet psychosocial a été peu exploré en République Démocratique du Congo. La présente étude a évalué la qualité de vie des patients tuberculeux pharmacorésistants (PTP) suivis au Centre d'Excellence Damien (CEDA) à Kinshasa. Méthodes. L'échelle de stress perçu (PSS), l'Hospital Anxiety and Depression Scale (HADS) et l'Indicateur de Santé Perceptuelle de NOTTINGHAM (ISPN) ont été utilisés dans une étude transversale réalisée du 1er avril au 31 décembre 2018 sur 81 PTP hospitalisés au CEDA de Kinshasa. La méthode de régression logistique a recherché les déterminants de la qualité de vie. Résultats. Au cours de la période de l'étude, 81 PTP étaient reçus dont 62 TB multirésistants (TB MR, 76,5%) contre 19 TB ultrarésistants (TBUR, 23,5%), constituant les deux groupes d'étude. L'âge moyen des sujets était de 34,7±14,3 ans. Les hommes étaient légèrement prépondérants (53 %) avec un sex ratio H/F de 1,1. La tranche d'âge de 21 à 30 ans était plus représentée (35%). Trois-quarts des sujets étaient solitaires (75%), plus de deuxtiers avaient un niveau secondaire (69%), plus de la moitié n'avait pas d'occupation (56%), près de deux-tiers fréquentaient les Eglises indépendantes (60%). Trente-cinq pourcents des patients avaient une mauvaise qualité de vie. Celle-ci était liée à l'âge >40 ans, au type TBMR, au retard d'accompagnement psychosocial, au niveau d'étude primaire, à la présence de la co-infection tuberculose- VIH/SIDA, au stress perçu et à l'anxiété-dépression. Conclusion. Les patients tuberculeux pharmacorésistants à Kinshasa ont une qualité de vie altérée. Cette situation est favorisée par l'âge >40 ans, le type de tuberculose pharmacorésistante, le retard d'accompagnement psychosocial, le faible niveau d'étude, la présence de la coinfection tuberculose-VIH/SIDA, le stress perçu, l'anxiété et la dépression.

Context and objective. Despite many progress in the treatment of drug-resistant tuberculosis, psychosocial aspects remain poorly adressed in the Democratic Republic of Congo. This study aimed to evaluate the quality of life of drugresistant tuberculosis patients. Methods. A crosssectional survey was conducted in hospitalized drug-resistant tuberculosis patients at CEDA Kinshasa, during the period from April 1 to December 31th, 2018, through the perceived stress scale (PSS), the Hospital Anxiety and Depression Scale (HADS) and the NOTTINGHAM Health Profil (NHP) tools. Data from 62 multdrug rerestitant TB patients (MDR TB, 76,5%) were compared with 19 ultraresistant (PXDR, 23.5 %) and analyzed, using a multivariate logistic regression analysis to assess the determinants of quality of life. Results. Among a total of 81 pharmaco-resistant TB patients, average age 34.7 ± 14.3 years, with a slight man preponderance (53 %), 35% had a poor quality of life. This was linked to age > 40 years, MDRTB type, delayed psychosocial support, primary education, the presence of TBHIV co-infection, and perceived stress and anxiety-depression. Conclusion.The study reveals an impaired quality of life in Drug-resistant tuberculosis patients in Kinshasa, with some identified correlates. Targeted measures are needed to improve the management of these patients

Prevalence and comorbidities of autism among children referred to the outpatient clinics for neurodevelopmental disorders.

INTRODUCTION: Autism spectrum disorders (ASD) is a neurodevelopmental disorder that has been rarely diagnosed in Sub-Saharan Africa. Although a proportion of children do present features of ASD in the Democratic Republic of Congo (DRC), little is known about it prevalence. Often, the co-morbidities constitute the upfront symptoms and therefore may it recognition and management difficult, aggravating as such the prognosis. The present study therefore aimed at studying the clinical profile of autism spectrum disorder (ASD) and the associated morbidities among children and adolescents in outpatient clinics in Kinshasa, the Democratic Republic of Congo. METHODS: We conducted a cross sectional study in the three outpatients centers receiving patients referred for neurodevelopmental disorders in Kinshasa, DRC, from June 2008 to June 2010. A total of 450 subjects aged from 1-18 years old were referred and included in the study. The clinical diagnosis for ASD was made using the DSM-IV-R and the ADIR. Co-morbidities were identified using DSM-IV-R criteria together with an extensive clinical interview and observation. All patients were subject to an intellectual quotient evaluation and an electroencephalogram reporting. RESULTS: Of the 450 subjects referred, 120 (29.3%) received the diagnosis of ASD, with boys outnumbering girls (OR 3:1. The mean age was 7.9 years (SD 3.4) (p< 0.001). Intellectual disability (75.83 %) and epilepsy (72.50%) were the main co-morbidities significantly associated with autism (p< 0.001). It was also found that co-morbidities were most frequent in subjects with an IQ<70 (p=0.05). CONCLUSION: ASD is frequent among patients referred for neurodevelopmental disorders in the three outpatients' centers for neurodevelopmental disorders in Kinshasa. Males seem to be more affected than female. The main co-morbidities were epilepsy and intellectual disabilities. Our findings suggest that it is important to screen for ASD and co-morbidities among all subjects referred for neurodevelopmental disorders and to undertake survey on ASD in various structures of rejected children from the society in Kinshasa DRC. This will help to identify and manage ASD and associated co-morbidities at an early stage for a better prognosis.
