M. K. Mbelu, J. J. Malemba, B. Kabengele, J. M. Kayembe, D. N. Kayembe
Journal of Tuberculosis Research (JTR) , 2018, DOI: 10.4236/jtr.2018.62015
Abstract: Context: The increase of serum lipase is established for pancreatic and bile duct disorders. However, the production of this enzyme by other organs, including the lungs, leads to the question of its potential role in the diagnosis of other conditions including lung diseases. Objective: The aim of the present study was to describe the profile of serum lipase in patients who suffered from the pulmonary tuberculosis and to identify its determinants. Patients and methods: A cross-sectional study was performed from July to October 2013 in four hospitals of Kinshasa (The University Hospital of Kinshasa, Lisanga medical Center and 2 medical centers of Save Army). Patients who suffered from tuberculosis were included. The levels of serum lipase, triglyceridemia, cholesterolemia, c-reactive protein were noted, as so as the hemogram profile and the prescribed treatment (category and phase). Results: One hundred and twenty-eight patients suffering from pulmonary tuberculosis were included. Forty three women (33.6%) and 85 men (66.4%). The sex ratio M/F was 1:9. Hyperlipasemia was observed in 44.5% of patients. The average level of serum lipase was 36.6 ± 5.0 IU/L (normal value: ≤ 38 IU/L) in tuberculosis patients and 30 ± 2.3 IU/L in controls The lipid profile of the patients was normal. Conclusion: L Hyperlipasemia can be encountered, in varying proportions, during pulmonary tuberculosis. It would be an indication of inflammation of the pulmonary parenchyma.

Abstract: Goal: Determining the place of Uricemia associated with other biochemical makers in the prediction of fetal-maternal complications during preeclampsia. Material and method: This is a prospective, cross-sectional study of 75 pre-eclamptic women in three maternities in Kinshasa, Democratic Republic of Congo, during the January to December 2013. The values of the following biochemical markers: uricemia, proteinuria and creatinemia were correlated with maternal and fetal prognosis. Results: This study showed that hyper uricemia associated with massive proteinuria and a high creatinine level correlated with an unfavorable pregnancy outcome and the occurrence of major materno-fetal complications such as eclampsia (X-squared = 24.3598, ddl = 2, p-value = 0.000005) and low birth weight (p = 0.001, R2 = 0.08). Conclusion: In view of these results, it appears necessary to ensure these biochemical markers systematically in the monitoring of pre-eclampsia.

Abstract: Objective: To assess the relationship between SCT, hemoglobin levels and anemia in CKD black patients. Method: A post-hoc analysis of data from 188 patients, enrolled in a cross-sectional study of sickle cell trait (SCT) and chronic kidney disease (CKD), was performed to assess the relationship between SCT, hemoglobin (Hb) levels and anemia defined as Hb < 12 g/dl in men and <11 g/dl in women. Student t test, Mann Whitney and Chi square test were used as appropriate for different comparisons. P < 0.05 defined the level of statistical significance. Results: SCT (HbAS) and normal hemoglobin (HbAA) were present in 39 (21%) and 149 (79%) CKD patients, respectively. Despite similar estimated GFR (eGFR) and age, HbAS patients had significantly lower Hb levels (8.8 ± 1.8 vs 10 ± 2.2 g/dl; p = 0.001) and a higher proportion of anemia (95% vs 72%, p = 0.001). In multiple linear regression analysis, eGFR, BMI, SBP and SCT emerged as independent determinants of Hb levels. The presence of SCT was associated with 1.185 g/dl decrease in Hb levels. Conclusion: In the present case series, SCT was associated with lower Hb levels suggesting its potential contribution to the pathogenesis of CKD-associated anemia.
Comparison of the Performance of Three Commonly Used Electrocardiographic Indexes for the Diagnosis of Left Ventricular Hypertrophy in Black Hypertensive Patients with Reduced Kidney Function Managed at a Tertiary Healthcare Hospital: A Post-Hoc Analysis  [PDF]
F. B. Lepira, C. M. B. Mpembe, F. I. N. Mbutiwi, J. R. Makulo, P. K. Kayembe, F. M. Kajingulu, E. V. Kintoki, J. R. M’buyamba-Kabangu
World Journal of Cardiovascular Diseases (WJCD) , 2017, DOI: 10.4236/wjcd.2017.74011
Background: Reduced kidney function in blacks is associated with an increased frequency of left ventricular hypertrophy. Given the unavailability of echocardiography in most developing countries, the diagnostic performance of current ECG indexes needs to be evaluated. Objective: To compare the diagnostic performance of 3 commonly used ECG indexes (Sokolow-Lyon, Cornell voltage and Cornell product) in black hypertensive patients. Methods: Electrocardiography and echocardiography estimated left ventricular mass of 155 consecutive hypertensive patients who participated from January 2012 to January 2013 to an echocardiographic cross-sectional study of left ventricular structure was analyzed to compare Cornell voltage and Cornell product indexes with Sokolow-Lyon voltage index as a reference. Reduced kidney function was defined as eGFR < 60 ml/min/1.730.05 m2. ROC curves in relation to LVH diagnosis were used to estimate the sensitivities and specificities of each index. P < 0.05 defined the level of the statistical significance. Results: The sensitivity and specificity were 43% and 85%, 23% and 77% and 26% and 77% for Sokolow-Lyon, Cornell voltage and Cornell product indexes, respectively. However, Sokolow-Lyon index (AUC; 95% CI: 0.64; 0.50 - 0.78) showed better performance than Cornell voltage (0.42; 0.25 - 0.59) and Cornell product (0.43; 0.28 - 0.59). Sokolow-Lyon index cut-point ≥ 37 mm corresponded to the highest Youden index (39.4% of sensitivity and 92.3% of specificity). Conclusion: Although the overall performance of the 3 ECG indexes versus echocardiography was low, Sokolow-Lyon index performed better than the two other indexes in diagnosing LVH.

Abstract: Background: There is paucity of literature on the determination of the root canal length of Bantu subjects in dental professional practicing in Africa and Democratic Republic of Congo in particular. Aims: The aim of the present study was to determine the root canal length of teeth of Bantu patients extracts attending the Teaching Hospital of Kinshasa University. Methods and Material: Prospective cross-sectional study was carried out in the service of Conservative Dentistry. The patients suffering with pulpitis of permanent teeth which were selected for root canal treatment during the period of January 2014 to December 2016 were included. All patients whose main root canals were inaccessible, teeth carrying prosthesis, teeth with large coronal decay, teeth having periapical periodontitis, supernumerary teeth, wisdom and primary teeth were excluded. Results: The upper canines presented some significant longer canals compared to the lower canine (23.4 ± 2.3 mm and 21.6 ± 1.8 mm). Palatal canals of the first and second molar were respectively longer as compared to the superior teeth canals (21.5 ± 1 mm, 21.3 ± 2 mm). The distal canals of the first and second molar were the longest in the mandibular arch respectively measuring 20.7 ± 2.0 mm and 21.5 ± 1.7 mm. Conclusion: Data obtained from Bantu patients show slightly shorter roots compared to some European populations, but longer than some Asian populations.

Journal of Tuberculosis Research (JTR) , 2017, DOI: 10.4236/jtr.2017.51004
Abstract: Introduction: To participate effectively in the fight against tuberculosis (TB), mothers need to have a good knowledge of TB and its prevention. The objective of this study was to evaluate the knowledge of mothers about TB and Bacillus Calmette Guérin (BCG). Methods: This was a cross-sectional survey performed from September to December 2015 in 4 health care facilities of Kinshasa. It concerned mothers of children who received BCG vaccine. The frequencies and chi-square of Pearson were used to report results. Results: A total of 380 couples of the children and their mothers were recruited. The median age of children was 16 months (ranges: 6 days to 59 months); 224 (58.9%) of them received BCG during the period recommended; 62 (16.3%) experienced a side effect. There was a significant association (p = 0.00) between sides effects and the delayed vaccination. The average age of the mothers was 29.3 ± 6.4 years; 352 (92.6%) had heard about TB; 28 (7.4%) never heard about it; 168 (44.2%) knew that TB is a contagious disease; only 111 (29.2%) knew the mode of transmission; 87 (22.9%) did not know any signs of TB, and 54 (14.2%) knew about prevention with the BCG vaccine. Factors significantly associated with the mothers’ lack of knowledge were a low level of education (p = 0.01), young age (p = 0.02), and place of residence (p = 0.04). Conclusion: There is an urgent need to improve the education of the population, particularly those who lives in poor conditions and who are uneducated.

Context: With the view to reorient both STI/HIV/AIDS prevention and adolescents pregnancies, this research study aims at evaluating cognitive and behavioral acquisitions, as well as the process of interactive sex education participatory approach among adolescents in Kinshasa high schools. Methods: Based on a “pre and post” virtually experimental design, two crosswise surveys were conducted in Kinshasa, for six months in 2011-2012 on 484 high school students (pre-survey) and on 441 high school students (post-survey), whose age range from 14 - 19 years including both sexes. Two participatory educational talks (PET) “A” and “B”, covered weekly in two different schools, were compared to a control group school. The PET “A” consisted of interactive interpersonal communication sessions given by an external expert as a substitute for the life education course in one school. The PET “B” carried out in another school, included more educational talk sessions, led by the external expert and supplemented by a close follow-up of teenagers divided into small groups of 10 participants. The subjects’ assessment was based on their knowledge, attitudes and practices relating to STI/HIV/AIDS dual prevention as well as to unwanted pregnancies. Results: The subjects involved in the PET “B” displayed a better/higher performance based on their knowledge, attitudes and practices related to STI/HIV/AIDS dual prevention and unwanted pregnancies. Broadly speaking, knowledge has been improved 6 times with the PET “B” (OR = 6, 10, IC 95%) (3.24 - 11.9), and 3 times with the PET “A” (OR = 3, 45, IC 95%) (1.79 - 6.81), compared to control school. Similarly, findings on subjects’ attitudes show an improvement rated 12 times with the PET”B” (OR = 11, 99, IC 95%) (5.67 - 27.38) and 5 times for the PET “A” (OR = 5.51, IC 95%) (2.54 - 12.87). As far as the subjects’ practices are concerned, an improvement of 6 more times of protected sexual intercourses with the PET “B” compared with the control school group (OR = 6, 52, IC 95%) (3.60 - 12.0). The process assessment records a spontaneous involvement of schools enhanced by the positive contribution of Life Education and Biology teachers; add a massive participation of adolescents who requested permanent PET program. Conclusion: The results of this study suggest that school sexual education programs can

Cartographie de la croissance urbaine de Kinshasa (R.D. Congo) entre 1995 et 2005 par télédétection satellitaire à haute résolution The mapping of the urban growth of Kinshasa (DRC) through high resolution remote sensing between 1995 and 2005

Abstract: La croissance spatiale de Kinshasa (RDC) est cartographiée par classification des espaces batis au départ d’images satellitaires SPOT datant de 1995 et 2005. D’après les résultats, la croissance de la ville est moins rapide que l’évolution démographique ; elle s’effectue désormais dans les espaces interstitiels en dépit de leurs fortes pentes et d’un certain éloignement des principales voies de communication (au delà d’1 km). The urban growth of Kinshasa (DRC) is mapped by classification of built-up areas using SPOT images dating from 1995 and 2005. From the results, the city growth is slower than the population growth; it is taking place within interstitial areas despite their steep slopes and their distance (1 km) from the main communication axes.

Abstract: In an epidemiological cross sectional study, a random sample of 524 pupils (263 boys, mean age of 18.7 ± 1.4 years) from school environment of Kinshasa were studied. Recorded parameters of interest were anthropometric, proteinuria, serum creatinine and estimated glomerular filtration rate (eGFR) according to the Schwartz formula using uncalibrated creatinine levels from one random measurement. CKD was defined as the presence of kidney damage (daily proteinuria ≥ 300 mg) and/or reduced kidney function (eGFR < 60 ml/min/1.73 m2). Concordances between eGFR according to Schwartz, Cockcroft-Gault (C-G) indexed for BSA and modification of diet in renal disease (MDRD) study equations were computed using the kappa coefficient.The prevalence of CKD by the Schwartz formula was 1.5%. By stage, 0.8% had CKD stage 1 (proteinuria with normal eGFR) and 0.8% had CKD stage 3 (eGFR, 30 to 59 ml/min/1.73 m2). The prevalence of proteinuria ≥ 300 mg/day was 1% (one case had 2.7g/day). Agreement between eGFR according to Schwartz formula and the MDRD formula was excellent (kappa: 88.8%). Although correlations between all formulas were excellent (0.99; 0.87, and 0.89), agreement was poor between eGFR according to Schwartz and C-G indexed BSA equation (kappa: 52.7%) and, poorer with C-G unadjusted for BSA (kappa: 26.9%).In the large African city of Kinshasa, 2% of high school students have CKD. This high prevalence rate emphasizes the need for appropriate detection and prevention measures in this vulnerable young age population group.

Abstract: Setting: The epidemiology of tuberculosis (TB) among children in the Democratic Republic of Congo (DRC) is not well known. Objective: This study aimed to describe the trends in TB epidemiology among children in the DRC and to compare these trends in children and adults. Design: Data from the National TB program, the WHO Global TB Report, and a demographic survey of health in the DRC were retrospectively analyzed. The study period was from 1995 to 2014. The notification rate, absolute incidence and incidence rate of TB per 100,000 population were reported. Results: In 2014, 12,785 (12.6% of adult cases) TB cases were reported in children and 101,303 in adults. Among children, 3438 (26.89%) had PTB+; 2828 (22.11%) had PTB; and 6519 (50.98%) had extrapulmonary TB (EPTB). Children under 5 years had a lower reported prevalence of TB (184 cases). The incidence rate per 100,000 population was 10 in children and 181 in adults. The TB incidence decreased between 2010 (11.47) and 2014 (10.46). The proportion of children in overall cases of PTB+ was 4% to 5% in all districts. Conclusion: Caring for childhood TB remains a challenge in the DRC. Improved diagnostic procedures and effective training of providers who care for childhood TB are needed.
