Clinical Characteristics and Outcomes of Patients Hospitalized for COVID-19 in Africa: Early Insights from the Democratic Republic of the Congo.

.Little is known about the clinical features and outcomes of SARS-CoV-2 infection in Africa. We conducted a retrospective cohort study of patients hospitalized for COVID-19 between March 10, 2020 and July 31, 2020 at seven hospitals in Kinshasa, Democratic Republic of the Congo (DRC). Outcomes included clinical improvement within 30 days (primary) and in-hospital mortality (secondary). Of 766 confirmed COVID-19 cases, 500 (65.6%) were male, with a median (interquartile range [IQR]) age of 46 (34–58) years. One hundred ninety-one (25%) patients had severe/critical disease requiring admission in the intensive care unit (ICU). Six hundred twenty patients (80.9%) improved and were discharged within 30 days of admission. Overall in-hospital mortality was 13.2% (95% CI: 10.9–15.8), and almost 50% among those in the ICU. Independent risk factors for death were age < 20 years (adjusted hazard ratio [aHR] = 6.62, 95% CI: 1.85–23.64), 40–59 years (aHR = 4.45, 95% CI: 1.83–10.79), and ≥ 60 years (aHR = 13.63, 95% CI: 5.70–32.60) compared with those aged 20–39 years, with obesity (aHR = 2.30, 95% CI: 1.24–4.27), and with chronic kidney disease (aHR = 5.33, 95% CI: 1.85–15.35). In marginal structural model analysis, there was no statistically significant difference in odds of clinical improvement (adjusted odds ratio [aOR] = 1.53, 95% CI: 0.88–2.67, P = 0.132) nor risk of death (aOR = 0.65, 95% CI: 0.35–1.20) when comparing the use of chloroquine/azithromycin versus other treatments. In this DRC study, the high mortality among patients aged < 20 years and with severe/critical disease is of great concern, and requires further research for confirmation and targeted interventions.

Cataract surgery in Kinshasa-Is there a place for "Monovision"?

Monovision is a method of correcting presbyopia where one eye is focused for far and the other for near vision. It is a simple, cost-effective approach to overcome the loss of accommodation with age and to become spectacles independent. About 50 patients, where bilateral cataract extraction was indicated, were included in this study performed at the St. Joseph's Eye Hospital in Kinshasa (DR Congo). Small incision cataract surgery technique (SICS) was applied with the implantation of 6mm PMMA lenses in the capsular bag. IOL refractive power choice was made to achieve a post-operative refraction of -0.5 dpt for the eye selected for far vision. The second eye received an implant heading for a post-operative myopia of -1.5 dpt suitable for intermediated and near vision. According to the literature, monovision criteria have been regarded as fulfilled when (a) far vision was 0.5 (logMAR) or better and (b) near vision was P3 (0.40, Decimal 32cm) or better. Spectacle dependence after bilateral cataract surgery heading for monovision was analysed using a dedicated questionnaire. Out of all 50 patients 22 (44%) fulfilled the above defined criteria of monovision in terms of post-operative refraction and visual acuity. About 19 out of these 22 (86.3%) patients were happy without glasses. Two of them used bifocal spectacles, whereas the remaining patient refused spectacles. About 28 patients did not fulfill monovision criteria. Out of these 28 patients, however, 9 (32.1%) of them are happy without glasses. In view of the described local circumstances aiming for monovision after bilateral cataract surgery is a suitable approach to optimise cataract surgical outcomes with no extra costs for surgery but considerable improvement of patient's visual performance in daily life.

Neonatal Outcome of Induced Prematurity for Severe Preeclampsia in Four Great Kinshasa Maternities

Severe preeclampsia (SPE) is associated with fetal complications including intrauterine growth retardation (IUGR), prematurity and in utero fetal death. Its treatment remains child birth that often is planned before term. However, this attitude can lead to fetal complications related to prematurity. Several studies on preeclampsia have already been studied in the DRC and several aspects have already been realized, but to date, the neonatal outcome has not yet been addressed. Methods: This is cross-sectional study performed in four public hospitals in Kinshasa (Democratic Republic of Congo). We included 400 cases of induced prematurity (IP) for SPE; the analysis compared pregnant women who gave birth before 34 weeks of amenorrhea (WA) and those after 34 WA. The comparison of the proportions was made by the Chi-square test and the calculation of Means by the Student’s test. The significance level was set at P Objective: To determine the frequency of induced prematurity for severe preeclampsia (SPE), to identify the indications and to evaluate neonatal outcome. Results: The IP frequency for SPE was 46.2%. The retro placental hematoma was the most indication in pregnancies before 34 WA 24.9%, while high blood pressure 54.5% in the after 34 WA group. In utero death was more common in pregnant women who gave birth before 34 weeks 25.4%; chronic fetal distress was elevated in the after 34 WA group 19.5%. Neonatal infection was more common in the group after 34 WA 49.4%, while respiratory distress 39.6%, intra and periventricular hemorrhage 19.5% and neonatal death 39.6% were more in group before 34 WA. Conclusion: Prematurity induced for SPE is related to a poor neonatal prognosis.

The Profile of Glycated Hemoglobin in Non-Diabetic Pregnant Women with Preeclampsia: A Case-Control Study in Kinshasa, the Democratic Republic of Congo

Background: A disturbed glucose metabolism is quite common during pregnancy. It is due to the diabetogenic potential of pregnancy and responsible for many obstetric complications. The glycated hemoglobin is one of the markers used to depict these disorders. Higher concentrations of this marker would be associated with unfavorable results of pregnancy. Objective: To describe the profile of HbA1c in non-diabetic preeclamptic pregnant women and to establish the association between the values of this marker and the maternal and fetal complications. Materials and Method: This is a case-control study of 142 pregnant women in their second and third trimester. They were followed in the maternity hospitals of University Clinics and the General Reference Hospital in Kinshasa, Democratic Republic of Congo between May and October 2019. The sampling of preeclamptic pregnant women was exhaustive. Controls were healthy pregnant women carrying pregnancies of the same type and of the same gestational age as the cases. Ultimately, 71 were preeclamptic and 71 healthy (controls). HbA1c was determined by immunoturbidimetry. Results: A total of 142 pregnant women took part in this study consisting of 71 preeclamptic women (cases) and 71 healthy pregnant women (controls). The average age of these pregnant women was 28.8 ± 6.8 (28.2 ± 6.8 years vs 29.5 ± 6.8 years p = 0.559), with an average parity of 2.3 ± 1.5 (2.2 ± 1.7 vs 2.4 ± 1.2, p = 0.005). The majority were carriers of monofoetal pregnancy. Higher HbA1c values were observed in the preeclamptic pregnant women compared to the controls (5.7 ± 1.3% vs 4.8 ± 0.7%, p 0.001). The proportion of pregnant women with pathological HbA1c values (>5.6%) was also higher in the group of preeclamptic pregnant women (46.5% vs 9.9%, p Conclusion: This study established that 46.5% of non-diabetic pregnant women with preeclampsia have high HbA1c values, which moreover are associated with preeclampsia and its complications. Systematic screening is essential for detecting preeclampsia or diabetes or both.

Magnitude of elevated iron stores and risk associated in steady state sickle cell anemia Congolese children: a cross sectional study

BackgroundThe serum ferritin assay is recommended in Sickle Cell Anemia (SCA) patients receiving regular transfusions. According to several authors, elevated iron stores indicating iron chelation corresponds to hyperferritinemia ≥500 ng/ml, and becomes detectable after twenty blood transfusions. The objectives of the study were to determine the prevalence of elevated iron stores and identify associated risk factors in a case series of Steady state SCA Congolese children.Material and methodsSerum ferritin was assayed in Steady state SCA children followed in 2 specialized hospitals in Kinshasa. Elevated iron stores was defined as serum ferritin level ≥ 500 ng/ml, and the associated risk factors were identified using univariate analysis.ResultsSeventy patients (median age 9 years, 56% boys, 53% receiving hydroxyurea) were selected in the study. Serum ferritin levels ranged from 24 to 2584 ng / ml with 21.4% of children having elevated iron stores. Mean levels of LDH, indirect bilirubin, plasma free Hb and CRP were similar between the 2 groups whereas history of polytransfusions (> 3 during the last year) was more frequent among patients with elevated iron stores (73% vs. 44%, p = 0.078). Receiving > 3 transfusions in a year vs. 0 was the main risk factor associated with elevated iron stores [OR 6.17 (95% CI: 1.81–20.96)].ConclusionIn SCA children, hyperferritinemia requiring iron chelation is most strongly related to blood transfusion. This situation concerned almost one in five children in present study; this shows the magnitude of the problem which is underestimated.

Risk factors and management of obstetric fistula associated with bladder calculus at Saint Joseph Hospital, Kinshasa - DR Congo

Aims: Obstetric fistula can be complicated by bladder calculus. The mechanism of lithogenesis is caused by some predisposing factors. The article aims to describe risk factors predisposing to bladder calculus formation and repair outcome.&#x0D; Methods: This was a comprehensive retrospective review from medical records of fistula obstetric repairs associated with bladder calculus at Saint Joseph Hospital in Kinshasa, DR Congo, from January 2007 to December 2017.&#x0D; Results: Among 1416 women who had had obstetric fistula, 30 (2.12%) had bladder calculus. The average age of women was 38 years old and ranged between 22 and 82 years old. The average duration of fistula was 8 years and ranged from 5 months to 31 years. All fistulas were iatrogenic and 86.67% (n = 26) occurred after caesarean section. Size of calculus varied between 1 cm and 15 cm. Risk factors identified were: urinary tract infection 80% (n = 24), foreign bodies 13.33% (n = 4), malnutrition and dehydration in 33.33%. In majority of cases (90%), the removal of the calculus and repair of fistula were performed at the same time by transvesical way. 70.37% of the patients had successful repairs.&#x0D; Conclusions: Iatrogenic fistula after caesarean section, urinary tract infection and foreign bodies are related to the formation of bladder calculi. Fistula repair and extraction of bladder calculus performed at the same time gives good results. Access to Obstetric Emergency Care, qualified personnel and available infrastructure and equipment are important for the prevention of the occurrence of bladder calculus.

Molecular identification of Plasmodium species in symptomatic children of Democratic Republic of Congo

BackgroundWorldwide, the highest malaria mortality is due to Plasmodium falciparum infection. However, other species of Plasmodium (Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi) can also cause malaria. Therefore, accurate identification of malaria species is crucial for patient management and epidemiological surveillance. This study aimed to determine the different Plasmodium species causing malaria in children under 5 years old in two provinces (Kinshasa and North Kivu) of the Democratic Republic of Congo (DRC).MethodsFrom October to December 2015, a health-facility based cross-sectional study was conducted in General Reference Hospitals in Kinshasa and North Kivu. Four hundred and seven blood samples were collected from febrile children aged ≤ 5 years. Nested polymerase chain reaction assays were performed for Plasmodium species identification.ResultsOut of 407 children, 142 (34.9%) were infected with Plasmodium spp. and P. falciparum was the most prevalent species (99.2%). Among those infected children, 124 had a mono infection with P. falciparum and one with P. malariae. Mixed infections with P. falciparum/P. malariae and P. falciparum/P. vivax were observed in 6 (1.5%) and 8 (2.0%) children, respectively. The prevalence of infection was higher in females (64.8%) than in males (35.2%), p < 0.001. The age-specific distribution of infection showed that children of less than 2 years old were less infected (18.4%) compared to those aged above 2 years (81.6%), p < 0.001.ConclusionAlthough this study showed clearly that the most prevalent species identified was P. falciparum, the findings demonstrate the existence of non-falciparum malaria, especially P. malariae and P. vivax among children aged ≤ 5 years living both Kinshasa and North Kivu Provinces in DRC.

P7 - Diagnosis of tuberculosis in patients infected with HIV from urine: experience of Ngaba (CHME, Ngaba) mother and child referral hospital in Kinshasa, Congo

P7 - Diagnosis of tuberculosis in patients infected with HIV from urine: experience of Ngaba (CHME, Ngaba) mother and child referral hospital in Kinshasa, Congo

Observational study shows that it is feasible to provide neuroprotective treatment for neonatal encephalopathy in low-income countries.

Perinatal asphyxia is one of the most frequent causes of neonatal morbidity and mortality worldwide, and 96% of the burden of neonatal encephalopathy occurs in low-income countries. This study investigated the feasibility of providing neuroprotective treatment for neonatal encephalopathy in low-income countries. Neonates with a gestational age of at least 36weeks, with signs of perinatal asphyxia, were included in this 2015 observational study in three hospitals in Kinshasa, capital of the Democratic Republic of Congo. Their characteristics were described, including the time to admission and Thompson score on admission. We found that 42 of 134 patients (31.3%) reached the hospital within six hours of birth with a Thompson score of at least seven on admission. Another 15 patients (11.2%) had a five-minute Apgar score of up to five, without a Thompson score, and were eligible for treatment. Of the 57 (42.5%) eligible patients, 31 were discharged (54.4%), 25 died (43.9%) and one (1.8%) remained in hospital at the end of the study. Interventional studies are feasible and necessary, especially in countries where the burden of neonatal encephalopathy is largest. A Thompson score of 7-15 might be a useful entry criterion for neuroprotective treatment in low-income countries.

Fréquence de l’ulcère cornéen à propos de 380 cas : étude rétrospective menée dans deux centres hospitaliers en RD Congo

To determine the frequency of corneal ulcer in our practice environment. This study was conducted at Saint-Joseph Hospital in Kinshasa and at the Lubumbashi University Clinics in the Democratic Republic of Congo from January 2011 to December 2014. We studied the frequency, demographic and clinical variables of corneal ulcer patients. A total of 380 cases of corneal ulcers were recorded out of 44,722 ophthalmologic consultations performed, with a frequency of 0.85% and a sex ratio ranging from 1.4 to 1.7 men to women. Corneal ulcer was diagnosed in patients of all ages; the mean age was 38.67±18.67 years. Patients with corneal ulcers presented for eye pain (80%), followed by tearing, photophobia, eye redness and blurred vision. The frequency of visual impairment was 10.30%; 2.1% of patients had vision reduced to light perception, and 1% of patients had no light perception. Corneal dystrophy was present in 41.6% of cases. Perforation of the globe and endophthalmitis were observed in 3.4% of cases each. Corneal ulceration is one of the leading causes of visual impairment and blindness in our practice environment. An early ophthalmologic consultation at the onset of symptoms and adequate management would improve the visual prognosis of patients.

Serum Lipase in Pulmonary Tuberculosis Patients in Kinshasa—A Hospital Based Study

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.

Seric Calcium and Magnesium in Normal and Pre Eclamptic Pregnant Women: A Case-Control Study in Kinshasa, D R Congo

Goal: The present study aimed to determine the profile of seric calcium and magnesium in pre-eclamptic and eclamptic pregnant women of Kinshasa province in the Democratic Republic of Congo where preeclampsia is characterized not only by a high incidence, but also by a seasonal variation probably related to nutritional intake. Study Design: This is a case-control study that took place during the period from September 2014 to March 2015 in four quaternary and tertiary maternity hospitals in Kinshasa. A total of 113 healthy pregnant women (controls) and 112 pre-eclamptic and eclamptic pregnant women (cases) were included in this study. Seric calcium and magnesium were measured in all these gravidas by the principle of spectrophotometry with a HUMALYSER Primus semi-automaton. Results: The mean age of those gravidas was 26.8 ± 6.3 years (26.7 vs 26.9, p = 0.11). The majority of these gravidas were primiparous. The mean gestational age in both groups was 31.35 ± 0.9 weeks (32.1 vs 30.6, p = 0.21). The average seric calcium value was 4.47 ± 0.23 mEq /L in healthy pregnant women compared to 3.80 ± 0.71 mEq/l in pre-eclamptics (P 0.001). The mean of seric magnesium was 1.56 ± 0.15 mg/dL in healthy pregnant women compared to 1.20 ± 0.41 mg/dL in pre eclamptics (P 0.001). Seric calcium and magnesium values were low in the pre-eclamptic group and lower in the eclamptic group (P 0.001). Conclusion: This study establishes a relationship between the low concentration of seric calcium and magnesium with pre-eclampsia and eclampsia, which could be one of the determinants of the high prevalence and seasonality of the disease in Kinshasa.

Forced sexual intercourse and its association with HIV status among people attending HIV Voluntary Counseling and Testing in a healthcare center in Kinshasa (DRC).

IntroductionSexual violence, an HIV determinant, is an integrated behavior in the D.R.Congo. We aimed to analyze the prevalence of forced sexual intercourse (FSI) among people receiving HIV Voluntary Counseling and Testing in a hospital in Kinshasa, and its association with socio-demographics, behaviors and HIV status.MethodologyCase-control study (2010–2012). Two-hundred and seventy-four cases with a new HIV+ test and 1,340 controls with an HIV- test were interviewed about HIV-related knowledge, attitudes and behaviors, including FSI.ResultsThirty-four percent of the participants declared having had FSI (38% of women and 32% of men). Being a woman, aged 25–49 and reporting multiple sexual partners were associated with reporting FSI. For men, being single was protective against FSI; and cohabiting, having a high socioeconomic status, and alcohol consumption increased the odds. For women, being single, divorced/separated and widow was associated with reporting FSI. A significant positive association was found between FSI and an HIV positive test.ConclusionAmong our Congolese population, FSI was strongly associated with HIV infection and it was also associated with alcohol consumption and multiple sexual partnerships, other key HIV determinants. These behaviors need to be identified as potential risk factors of FSI during counseling interventions. Researchers, practitioners and decision-makers should work together to get violence prevention integrated into health, social and educational policies.

Perceptions and types of support coming from families caring for patients suffering from advanced illness in Kinshasa, Democratic Republic of Congo.

Perceptions of families who take care of patients suffering from advanced illness are rarely considered in Kinshasa medical practices; nevertheless, these families are the main actors involved in such care. The objective of this present study was to illustrate, in a Congolese context, the perceptions of families on the care of patients suffering from advanced illness, and to identify the possible aids provided by healthcare facilities. A qualitative study was performed among focus groups in six hospitals in Kinshasa. Each group included eight members. We gathered factors that could negatively influence the care of a patient suffering from advanced disease. Such factors included: scarcity of and inaccessibility to painkillers, economic resilience, poor quality treatment, lack of psychological counselling, seeking alternative solutions and poor communication between caregivers and patients. In contrast, the study also showed that relatives caring for these patients often receive support from the wider family and from cult members. This study focuses on the miscommunication between healthcare workers and patients, poor management in advanced illness as well as a lack of psychological support from caregivers. The findings can serve as basis for further research in palliative care.

Pediatric pleural empyema: one of the management challenges in children of Democratic Republic of Congo

Empyema is a serious complication characterized by purulent exudate and bacteria in the pleural space, which may progress to necrosis, cavitations or fistulas in the thoracic cavity. It remains a major challenge throughout low-income countries. Objectives were to emphasize the role of basic medical and radiologic approach and to resolve a severe lung complication when facilities are inadequate. A five-year-old female was referred with distress respiratory to the Emergency Unit of Monkole, a large public-private missionary hospital in Kinshasa, Congo. Chest X-ray showed a massive empyema that was resolved by immediate drainage and antibiotiocs. Results were rapid improvement and discharge after 3 weeks. A classic medical and imaging approach is a winning return in low-income countries. According to the British Thoracic Society guidelines, pleural effusion with compromising respiratory function can be managed by drainage and antibiotics.

Chronic illness needing palliative care in Kinshasa hospitals, Democratic Republic of the Congo (DRC)

BackgroundChronic illnesses are a major public health problem in low-income countries. In the Democratic Republic of the Congo (DRC), few data are available, especially in palliative care. In this context, the present study aimed at describing the patterns of diseases in Kinshasa hospitals as well as risk factors associated with patients’ evolving status and length of hospital stay.MethodsA prospective study was conducted in ten hospitals of Kinshasa, over a 1-year period. A total of 2699 patients with a chronic condition (non-communicable diseases (NCD) and/or AIDS) were consecutively enrolled in the study between January and December, 2013.ResultsOut of 2699 patients studied, 36.9% were suffering from cardiovascular diseases, 29.7% from comorbidity and 17.5% from AIDS. 27.5% of patients died while hospitalized, and 67.4% were lost to follow-up. The risk factors independently associated with death in hospitals were AIDS (adjusted OR = 2.2) and age over 65 years old (adjusted OR = 1.7).Peri-urban and rural areas were significantly associated with a mean adjusted hospital stay longer than 3 days. The length of stay (LOS) was shorter for women and patients living in urban areas. Patients survived for a median of 10 days (range 7–20 days).ConclusionsThis study reveals the high proportion of patients suffering from advanced chronic diseases, including cardiovascular diseases, AIDS and comorbidity. It demonstrates the need for palliative care (PC) in medical practices in Kinshasa, the capital of the Democratic Republic of the Congo.

Stroke characterization in Sun Saharan Africa: Congolese population

BackgroundStroke is the second cause of death worldwide and over than 80% of deaths occurs in developing countries. However, its characteristics in the Democratic Republic of Congo (DRC) are poorly defined. This study aimed to describe the key features of stroke in a hospital population of Kinshasa in DRC and to assess the frequency of cardiovascular risk factors and their impact on target organs. MethodsA descriptive study was carried out from three hospitals in Kinshasa between January and April 2013. Cardiovascular risk factors, clinical and biological data were collected during the study period. The study involved 166 patients aged 18years and over. ResultsThe mean age of patients was 59.6±12.3years, the sex ratio for male of 1.9. Stroke was ischemic in 66% of cases. Hypertension was the most frequent cardiovascular risk factor (84.3%), followed by high blood cholesterol (45.2%).The etiologies of ischemic stroke (TOAST classification) were dominated by lacunas (38.5%) and embolic heart diseases (12.8%). The origin was unknown in 45.9% of cases. Coma was observed in 37% of patients on admission and was the main independent prognostic factor of mortality, which was 19.3%. Left ventricular hypertrophy and renal failure were found respectively in 64.7% and 34% of patients. ConclusionThis study found a growing increase of ischemic stroke in a society where hemorrhagic type used to be the most common, a high rate of hypertension, hypercholesterolemia and diabetes, indicative of a fast epidemiological transition.

Prevalence of Circadian Blood Pressure Patterns and Factors Associated with Non-Dipping among Black Patients with Untreated and Treated Hypertension: A Cross-Sectional Study

Objective: To determine the prevalence of circadian BP patterns and to assess factors associated with the non-dipping pattern in untreated and treated hypertensive patients, studied separately. Methods: Clinical data and ABPM were obtained from 52 untreated and 168 treated hypertensive patients referred for ABPM to Monkole Hospital in Kinshasa. Twenty-four ABPM was performed using an oscillometric device. Non-dipping pattern encompasses non-dipping (nocturnal systolic BP dip less than 10% of daytime systolic BP) and reverse dipping (mean night SBP higher than the day SBP). Results: the prevalence of non-dipping pattern was 75% (63.5% non-dipping and 11.5% reverse dipping) and 70% (60.1% non-dipping and 10.1% reverse dipping) in untreated and treated hypertensive patients, respectively. Advanced age (adjusted OR 1.80; 95%CI 1.96 - 3.38; p = 0.015), female sex (adjusted OR 2.28; 95%CI 1.19 - 4.36; p = 0.013), diabetes (adjusted OR 5.06; 95%CI 1.38 - 6.95; p = 0.014), reduced kidney function (adjusted OR 3.10; 95%CI 1.50 - 6.43; p = 0.018), inflammation (adjusted OR 2.65; 95%CI 1.76 - 6.48; p = 0.031), LVH (adjusted OR 4.45; 95%CI 1.78 - 7.67; p = 0.024) and antihypertensive therapy (adjusted OR 0.19; 95%CI 0.12 - 0.64; p = 0.018) emerged as the main independent factors significantly associated with the non-dipping pattern in the study population. Conclusion: the non-dipping pattern was a common finding in studied patients and associated with traditional and emerging risk factors suggesting that this abnormal pattern could be a marker of high cardiovascular risk.

Male condom use, multiple sexual partners and HIV: a prospective case-control study in Kinshasa (DRC)

ABSTRACTIn the Democratic Republic of Congo no previous studies have assessed the factors associated with different patterns of condom use and with multiple sexual partners, and the association between condom use simultaneously taking into account multiple sexual partnerships, and HIV infection. We carried out a prospective case–control study. From December 2010 until June 2012, 1630 participants aged 15–49 getting HIV Voluntary Counseling and Testing in a hospital in Kinshasa were selected. Cases were new HIV diagnosis and controls were HIV-negative participants detected along the study period. We recruited 274 cases and 1340 controls that were interviewed about HIV-related knowledge, attitudes and behaviours. Among cases there was a high prevalence of multiple lifetime and concurrent sexual partnerships (89.8% and 20.4%, respectively) and most cases never used condoms with only 1.5% using them consistently. Condom use and multiple partnerships were associated with male, single and high-educated participants. An association was found between multiple lifetime partners and ‘any condom use’ (OR = 2.99; 95%CI: 2.14–4.19) but not with consistent use. Both having two or more multiple concurrent sexual partners or not using condoms were variables similarly and highly associated to HIV risk. The association found between having two or more concurrent sexual partners and HIV was slightly higher (OR = 3.58, 95%CI:2.31–5.56) than the association found between never condom use and HIV (OR = 3.38, 95%CI:1.15–9.93). We found a high prevalence of multiple lifetime sexual partners and an extremely high prevalence of inconsistent condom use, both strongly associated with HIV seropositivity. Local programmes would benefit from comprehensive interventions targeting all behavioural and sociocultural determinants.

Promoting the sustainable management of hospital waste in Kinshasa

The management of hospital waste is a high-risk practice in the hospitals of Kinshasa, the largest city of the Democratic Republic of the Congo, from the point of view of public health and the environment. A multi-criteria study carried out in 4 hospitals assessed the situation and put forward solutions.
