A possible case of spontaneous Loa loa encephalopathy associated with a glomerulopathy

It is well known that renal and neurological complications may occur after antifilarial treatment of patients infected with Loa loa. Conversely, spontaneous cases of visceral complications of loiasis have been rarely reported. A 31-year-old Congolese male patient who had not received any antifilarial drug developed oedema of the lower limbs, and then transient swellings of upper limbs. Two months after, he developed troubles of consciousness within several hours. At hospital, the patient was comatose with mild signs of localization. Laboratory tests and an abdominal echography revealed a chronic renal failure due to a glomerulopathy. Three weeks after admission, Loa microfilariae were found in the cerebrospinal fluid, and a calibrated blood smear revealed a Loa microfilaraemia of 74,200 microfilariae per ml. The level of consciousness of the patient improved spontaneously, without any specific treatment, but several days after becoming completely lucid, the patient died suddenly, from an undetermined cause. Unfortunately, no biopsy or autopsy could be performed. The role of Loa loa in the development of the renal and neurological troubles of this patient is questionable. But the fact that such troubles, which are known complications of Loa infection, were found concomitantly in a person harbouring a very high microfilarial load suggests that they might have been caused by the filarial parasite. In areas endemic for loiasis, examinations for a Loa infection should be systematically performed in patients presenting an encephalopathy or a glomerulopathy

Tests diagnostiques de l’infection à Coronavirus (COVID-19) : des atouts et des limites: Diagnosis testing for Coronavirus infection disease (COVID 19): Assets and limits

The world is going through a serious health crisis due to the COVID 19 pandemic. Although little is known about COVID-19, we have observed an increased interhuman transmission of etiological agent SARS-Cov-2 and we assume that each new cases of COVID-19 get at least two or three news persons infected. Therefore, the test for detection of the infection should be much implemented as an efficient strategy to fight against the COVID 19 pandemic. The COVID-19 diagnostic tests are an essential tool for assessing the pandemic. This review paper will discuss the advantages and limitations of the diagnosis tests for COVID 19. There are 2 categories of tests: those that directly detect the virus or its component, and those that search for the antibodies generated by the virus infection. The real time Reverse transcriptase Polymerase chain reaction (test rt-RT-PCR) remains the gold standard for the diagnosis of COVID-19. Its sensitivity on the nasopharynx swab seems high, though false negative cases can occur, with an average of 30% of cases. Serological test detect specific antibodies against SARS-COV-2. They help identify individuals that have been infected by the virus, those healed and that have acquired immunity against the virus. They are diagnosis orientation tests of COVID-19. Until now, none of these tests are 100% reliable, but they are used by a qualified collaborating medical staff. They can help identify the majority of the infected and immunized individuals. Le monde entier fait face à une crise sanitaire sans précédent due à la pandémie de maladie à virus SARS-COV-2 alias COVID-19. Malgré les connaissances très incomplètes sur la COVID-19, on a constaté une contagiosité interhumaine élevée au début de la pandémie actuelle, et on estime que chaque nouveau cas de COVID-19 infecte en moyenne deux à trois personnes. En conséquence, la stratégie de lutte contre la pandémie à COVID-19 qui ébranle nos sociétés passe nécessairement par une intensification des tests de détection de l’infection. Ces tests diagnostiques de la COVID-19 sont un outil essentiel pour suivre la propagation de la pandémie. Ainsi, l’objectif de la présente revue de la littérature est d’aborder le diagnostic de l’infection à Coronavirus (COVID-19) en s’attardant sur les tests de diagnostic, leurs atouts et leurs limites. Il y a deux catégories de test : ceux qui recherchent la présence directe du virus ou de ses fragments, et ceux qui recherchent les anticorps résultant de l’infection par le virus du COVID-19. Le test real time –Reverse Transcriptase –Polymerase chain reaction (rt-RT-PCR) reste le gold standard pour le diagnostic de la COVID-19. Sa sensibilité sur les écouvillons nasopharyngés semble élevée, mais des faux négatifs peuvent se produire, avec une fréquence incertaine (environ 30% des cas). Les tests sérologiques détectent les anticorps spécifiques du SARS-CoV-2. Ils permettent l’identification des individus qui ont été infectés par le virus, se sont rétablis, et ont développé, en théorie, une réponse immunitaire efficace contre le virus. Ils constituent des tests d’orientation diagnostique de la COVID-19. A ce jour, aucun de ces tests n’est fiable à 100 %, mais, utilisés par un personnel médical qualifié et en combinaison, ils permettent l’identification de la majorité des individus infectés et immunisés

Longitudinal analysis of sociodemographic, clinical and therapeutic factors of HIV-infected individuals in Kinshasa at antiretroviral therapy initiation during 2006-2017.

peer reviewedBACKGROUND: The benefits of antiretroviral therapy (ART) underpin the recommendations for the early detection of HIV infection and ART initiation. Late initiation (LI) of antiretroviral therapy compromises the benefits of ART both individually and in the community. Indeed, it promotes the transmission of infection and higher HIV-related morbidity and mortality with complicated and costly clinical management. This study aims to analyze the evolutionary trends in the median CD4 count, the median time to initiation of ART, the proportion of patients with advanced HIV disease at the initiation of ART between 2006 and 2017 and their factors. METHODS AND FINDINGS: HIV-positive adults (≥ 16 years old) who initiated ART between January 1, 2006 and December 31, 2017 in 25 HIV care facilities in Kinshasa, the capital of DRC, were eligible. The data were processed anonymously. LI is defined as CD4≤350 cells/μl and/or WHO clinical stage III or IV and advanced HIV disease (AHD), as CD4≤200 cells/μl and/or stage WHO clinic IV. Factors associated with advanced HIV disease at ART initiation were analyzed, irrespective of year of enrollment in HIV care, using logistic regression models. A total of 7278 patients (55% admitted after 2013) with an average age of 40.9 years were included. The majority were composed of women (71%), highly educated women (68%) and married or widowed women (61%). The median CD4 was 213 cells/μl, 76.7% of patients had CD4≤350 cells/μl, 46.1% had CD4≤200 cells/μl, and 59% of patients were at WHO clinical stages 3 or 4. Men had a more advanced clinical stage (p <0.046) and immunosuppression (p<0.0007) than women. Overall, 70% of patients started ART late, and 25% had AHD. Between 2006 and 2017, the median CD4 count increased from 190 cells/μl to 331 cells/μl (p<0.0001), and the proportions of patients with LI and AHD decreased from 76% to 47% (p< 0.0001) and from 18.7% to 8.9% (p<0.0001), respectively. The median time to initiation of ART after screening for HIV infection decreased from 40 to zero months (p<0.0001), and the proportion of time to initiation of ART in the month increased from 39 to 93.3% (p<0.0001) in the same period. The probability of LI of ART was higher in married couples (OR: 1.7; 95% CI: 1.3-2.3) (p<0.0007) and lower in patients with higher education (OR: 0.74; 95% CI: 0.64-0.86) (p<0.0001). CONCLUSION: Despite increasingly rapid treatment, the proportions of LI and AHD remain high. New approaches to early detection, the first condition for early ART and a key to ending the HIV epidemic, such as home and work HIV testing, HIV self-testing and screening at the point of service, must be implemented

Surveillance des décès aux Cliniques Universitaires de Kinshasa (RDC) : la COVID-19 a-t-elle entraîné une surmortalité ? Monitoring of deaths at the Kinshasa University Hospital: has COVID-19 resulted in increase of mortality?

Context and objectives. The extent of COVID-19 impact on overall in-hospital mortality is controversial. The objectives of the study were to compare the number of deaths in the first semesters of 2018, 2019 and 2020; determine the proportion of COVID-19 cases and identify the factors associated with COVID-19 among the deaths recorded at the morgue of the Kinshasa University Hospital (KUH).&nbsp;Methods. We collected death certificates registered at the KUH morgue. The diagnosis of COVID-19 was confirmed using RT-PCR in all suspected subjects (from March 2020), including those who have arrived dead. Pearson’s khi-square, Student’s t-test, and logistic regression were used as statistical tests.&nbsp;Results. The number of deaths recorded in the first semester of 2019 (868 cases) was higher than in 2020 (768 cases) and 2018 (744 cases). In 2020, 45 deaths related to COVID-19 (6.0%) were reported. The risk of COVID-19 depended on the period (month of June 2020, OR: 5.69; p = 0.002), sex (female, 0R: 0.42; p = 0.024) and age (one additional year of age, OR: 1.02; p = 0.009).&nbsp;Conclusion: COVID-19 did not lead to excess intra-hospital mortality in the first semester of 2020. The proportion of the disease among deceased patients was more marked in June 2020 and the risk increased with age, especially in men. Contexte et objectifs. L’ampleur de la COVID-19 sur la mortalité intra-hospitalière globale suscite des controverses. Les objectifs de l’étude étaient de comparer le nombre de décès lors des premiers semestres de 2018, 2019 et 2020 ; déterminer la proportion des cas de COVID-19 et identifier les facteurs associés à la COVID-19 parmi les décès enregistrés à la morgue des Cliniques Universitaires de Kinshasa (CUK).&nbsp;Méthodes. Nous avons colligé les certificats des décès enregistrés à la morgue des CUK. La COVID-19 a été recherchée par la RT-PCR chez tous les sujets suspects y compris les arrivés morts (à partir de mars 2020). Le Khi carré de Pearson, le test t de Student et la régression logistique ont été utilisés comme tests statistiques.&nbsp;Résultats. Le nombre de décès enregistrés au premier semestre 2019 (868 cas) était plus élevé qu’en 2020 (768 cas) et 2018 (744 cas). En 2020, on a rapporté 45 décès liés à la COVID-19 (6,0 %). Le risque d’avoir la COVID-19 dépendait de la période (mois de juin 2020, OR : 5,69 ; p = 0,002), du sexe (femme, 0R : 0,42 ; p = 0,024) et de l’âge (une année d’âge supplémentaire, OR : 1,02 ; p = 0,009).&nbsp;Conclusion. La COVID-19 n’a pas entraîné de surmortalité intra-hospitalière au premier semestre de l’année 2020. La proportion de la maladie parmi les patients décédés était plus marquée au mois de juin 2020 et le risque augmentait avec l’âge, particulièrement chez les hommes

Épidémiologie clinique et grande diversité génétique parmi les isolats de Cryptococcus spp. infectant les personnes vivant avec le VIH à Kinshasa, République démocratique du Congo

Neuromeningeal cryptococcosis (NMC) is a life-threatening opportunistic infection in advanced HIV disease patients (AHDP). It is caused by Cryptococcus spp. complexes and mainly occurs in sub-Saharan Africa. In this study, we performed molecular characterization and antifungal susceptibility profiling of Cryptococcus isolates from AHDP in Kinshasa (DRC). Additionally, we investigated a possible association between NMC severity factors and the Cryptococcus neoformans (Cn) multilocus sequence typing (MLST) profiles. We characterized the isolates using PCR serotyping, MALDI-TOF MS, internal transcribed spacer (ITS) sequencing, and MLST. Susceptibility testing for the major antifungal drugs was performed according to the EUCAST guidelines. Parameters associated with NMC severity, such as hypoglycorrhachia ( 30 cm H2O), and poor therapeutic outcome were compared with the Cn MLST sequences type (ST). Twenty-three out of 29 Cryptococcus isolates were identified as serotype A using PCR serotyping (79.3%; 95% IC: 65.5-93.1), while six (20.7%; 95% IC: 6.9-34.5) were not serotypable. The 29 isolates were identified by ITS sequencing as follows: Cryptococcus neoformans (23/29, 79.3%), Cutaneotrichosporon curvatus (previously called Cryptococcus curvatus) (5/29, 17.2%), and Papiliotrema laurentii (Cryptococcus laurentii) (1/29, 3.5%). Using the ISHAM MLST scheme, all Cn isolates were identified as molecular type VNI. These comprised seven different STs: ST93 (n = 15), ST5 (n = 2), ST53 (n = 1), ST31 (n = 1), ST4 (n = 1), ST69 (n = 1), and one novel ST that has not yet been reported from other parts of the world and was subsequently assigned as ST659 (n = 2). Of the included strains, only Papiliotrema laurentii was resistant to amphoterin B (1/29, 3.5%), 6.8% (2/29) were resistant to 5-flucytosine (the single Papiliotrema laurentii strain and one Cryptococcus neoformans isolate), and 13.8% (4/29) to fluconazole, including two of five (40%) Cutaneotrichosporon curvatus and two of 23 (8.7%) C. neoformans strains. We found a significative association between poor therapeutic outcome and a non-ST93 sequence type of causative strains (these concerned the less common sequence types: ST53, ST31, ST5, ST4, ST659, and ST69) (87.5% versus 40%, p = 0.02). Molecular analysis of Cryptococcus spp. isolates showed a wide species diversity and genetic heterogenicity of Cn within the VNI molecular type. Furthermore, it is worrying that among included strains we found resistances to several of the commonly used antifungals.Cryptococcose chez les personnes vivant avec le VIH à Kinshasa : étude épidémiologique et moléculaire3.

Retention in care and predictors of attrition among HIV-infected patients who started antiretroviral therapy in Kinshasa, DRC, before and after the implementation of the ‘treat-all’ strategy

peer reviewedThe retention of patients in care is a key pillar of the continuum of HIV care. It has been suggested that the implementation of a “treat-all” strategy may favor attrition (death or lost to follow-up, as opposed to retention), specifically in the subgroup of asymptomatic people living with HIV (PLWH) with high CD4 counts. Attrition in HIV care could mitigate the success of universal antiretroviral therapy (ART) in resource-limited settings. We performed a retrospective study of PLWH at least 15 years old initiating ART in 85 HIV care centers in Kinshasa, Democratic Republic of Congo (DRC), between 2010 and 2019, with the objective of measuring attrition and to define factors associated with it. Sociodemographic and clinical characteristics recorded at ART initiation included sex, age, weight, height, WHO HIV stage, pregnancy, baseline CD4 cell count, start date of ART, and baseline and last ART regimen. Attrition was defined as death or loss to follow-up (LTFU). LTFU was defined as “not presenting to an HIV care center for at least 180 days after the date of a last missed visit, without a notification of death or transfer”. Kaplan–Meier curves were used to present attrition data, and mixed effects Cox regression models determined factors associated with attrition. The results compared were before and after the implementation of the “treat-all” strategy. A total of 15,762 PLWH were included in the study. Overall, retention in HIV care was 83% at twelve months and 77% after two years of follow-up. The risk of attrition increased with advanced HIV disease and the size of the HIV care center. Time to ART initiation greater than seven days after diagnosis and Cotrimoxazole prophylaxis was associated with a reduced risk of attrition. The implementation of the “treat-all” strategy modified the clinical characteristics of PLWH toward higher CD4 cell counts and a greater proportion of patients at WHO stages I and II at treatment initiation. Initiation of ART after the implementation of the ‘treat all” strategy was associated with higher attrition (p<0.0001) and higher LTFU (p<0.0001). Attrition has remained high in recent years. The implementation of the “treat-all” strategy was associated with higher attrition and LTFU in our study. Interventions to improve early and ongoing commitment to care are needed, with specific attention to high-risk groups to improve ART coverage and limit HIV transmission

Factors associated with acceptability of HIV self-testing (HIVST) among university students in a Peri-Urban area of the Democratic Republic of Congo (DRC)

Introduction:&nbsp;this paper examines the acceptability of HIV self-testing (HIVST) by students in a university in the DRC and identifies factors associated with uptake of HIVST. Methods:&nbsp;a cross-sectional study was conducted with a sample of 290 students from Kikwit University. Data were summarized using proportions and predictions of acceptability of HIVST by logistic regression. Results:&nbsp;the average age of students was 22.5 years, with the majority of the students being male (57%). Just over half the students sampled, reported being sexually active (51.8%). One hundred and sixty four (75%) reported that they had one sexual partner and fifty-six (25%) two or more sexual partners in the past year. Sixty-six percent had used condoms during their last sexual encounter. The acceptability of HIVST was high (81.4%) and 66.1% of students stated that they would confirm the self-test at a local health facility. The knowledge about the importance of the self-test (OR 5.02; 95% CI:1.33-18.88; p=0.017), the perception that counseling pre and post-test were important (OR 2.91; 95% CI:1.63-5.19; p &lt; 0.0001) and the willingness to realize the test with a partner (OR 2.46; 95% CI:1.43-4.23; p=0.034) were factors associated with HIVST. Conclusion:&nbsp;the acceptability of HIVST was high and therefore its implementation is feasible in our country. However, prior to implementation, additional factors such as cost; access of HIVST; false reassurance of the test; missed early infections in the window period, limited counseling and linkage to care options, need to be considered

Decrease in late presentation for HIV care in Kinshasa, DRC, 2006-2020.

peer reviewedINTRODUCTION: Late presentation for HIV care is a well-described issue for the success of ART outcomes and the cause of higher morbidity, mortality and further transmission. Monitoring the level of late presentation and understanding the factors associated with it would help to tailor screening and information strategies for better efficiency. We performed a retrospective cohort study in Kinshasa, the capital of the DRC. The studied population included HIV-positive adults newly enrolled in HIV care between January 2006 and June 2020 at 25 HIV urban care facilities. Patient information collected at presentation for HIV care included age, sex, WHO clinical stage and screening context. We used 2 definitions of late presentation: the WHO definition of advanced HIV disease (WHO stage 3/4 or CD4 cell count < 200 cells/mm(3)) and a more inclusive definition (WHO stage 3/4 or CD4 cell count < 350 cells/mm(3)). RESULTS: A total of 10,137 HIV-infected individuals were included in the analysis. The median age was 40 years; 68% were female. A total of 45.9% or 47.5% of the patients were late presenters, depending on the definition used. The percentage of patients with late presentation (defined as WHO stage 3/4 or CD4 cell count < 350 cells/mm(3)) decreased during recent years, from 70.7% in 2013 to 46.5% in 2017 and 23.4% in 2020. Age was associated with a significantly higher risk of LP (p < 0.0001). We did not observe any impact of sex. CONCLUSIONS: The frequency of late presentation for care is decreasing in Kinshasa, DRC. Efforts have to be continued. In particular, the issue of late diagnosis in older individuals should be addressed
