A Descriptive Study of Perinatal Asphyxia at the University Hospital of Kinshasa (Democratic Republic Of Congo)

Perinatal asphyxia is the third cause of neonatal death after prematurity and infection. The purpose of this study was to determine the incidence, the etiology and the HIE score at the first day in term and near-term newborns with perinatal asphyxia at the University Hospital of Kinshasa. 50 term and near-term neonates with perinatal asphyxia were studied prospectively after they were admitted in neonatal intensive care from November 2009 to January 2011. For each patient admitted the perinatal data were collected. Clinical assessment was performed by the Sarnat grading and the Thompson score within twenty-four hours. Medcalc® was used for statistics. 50 babies were scored. The median maternal age was 31 years. In 22% of the mothers preeclampsia was diagnosed. Urogenital infection, IUGR were other prenatal diagnoses. Median Apgar score was 4 after 1 minute, 5 after 5 minutes and 6 after 10 minutes. Sarnat grade 1 was seen in 16 patients, Sarnat grade 2 in 20 patients and grade 3 in 8. Thompson score in the first 24 hours was more than 7 in 60% of the patients. A good correlation was found between the Thompson score and the Sarnat grade (r: 0,77; p < 0,0001). 14 of the 50 babies died. Both Sarnat and Thompson score correlated significantly with mortality. The incidence of perinatal asphyxia at the University Hospital of Kinshasa remains high and the majority of patients had a severe HIE.

The phenotype and genotype of rheumatoid arthritis in the Democratic Republic of Congo

IntroductionLittle is known about rheumatoid arthritis in the black, particularly in Congolese, populations. Our objective was to describe the phenotype and genotype of rheumatoid arthritis (RA) in Congolese.MethodsAll consecutive rheumatoid arthritis (RA) patients attending Kinshasa University Hospital in a three-year time period were included. Demographics, clinical features and tobacco consumption were noted. Disease Activity Score (DAS)-28 based on the erythrocyte sedimentation rate (ESR), Health Assessment Questionnaire (HAQ), anti-citrullinated peptide antibodies (CCP) antibodies and rheumatoid factor (RF) were determined. Radiographs were scored according to Sharp-van der Heijde. On a subset of patients and controls HLA-DRB1 typing was performed.ResultsA total of 114 females and 14 males aged 51.2 ± 14.9 were included. Mean duration of symptoms was four years. Moderate tobacco consumption was reported in a minority of patients. DAS-28 at first visit was >5.1 and HAQ ≥0.5 in all patients. X-rays showed joint erosions and/or joint space narrowing, mostly of a moderate grade in 55.8% of patients. Anti-CCP and/or RF were present in 48.6% of patients with available data (n = 72) and in 3.0% of controls (n = 67). Radiographic changes and nodules were more frequent in RF or anti-CCP positive patients. One copy of the shared epitope was found in 13 patients (35.1%) and 3 controls (12.5%). Two copies were found in one patient (2.7%) and in one control (4.2%).ConclusionCongolese patients with RA consult long after disease onset. Despite this delay, the majority presents without major damage and is RF, anti-CCP and SE negative. We put forward the hypothesis that besides different environmental factors there is probably also a particular genetic risk profile in Congolese patients, different from the HLA-DRB1 shared epitope.

Acute renal failure in Congolese children: a tertiary institution experience

Published data on acute renal failure in children from the Democratic Republic of Congo are rare. The objective of this study was to review clinical manifestations, aetiologies and outcome in hospitalized children with acute renal failure. A retrospective study at Pediatric Nephrology Unit of University Hospital of Kinshasa was carried out. Fifty-six children with acute renal failure were eligible. There were 31 boys (55.4%) and 25 girls (44.6%) with a sex ratio of 1.24. The median age was 6.7 years (range 1-13 years). Fever (80.3%), oligo-anuria (73.2%), jaundice (67.9%) were the common clinical presentation. Blackwater fever (42.8%) was the leading cause of Acute Renal Failure. The incidence of severe dehydration because of gastroenteritis was low (5.3%). Around 12.5% of patients' misused herbal plants. Acute Peritoneal Dialysis was indicated in 15/56 children and only performed in four patients. Fourteen children (25%) died. A wide spectrum of features was seen in hospitalized Acute Renal Failure children and limited access to Acute Peritoneal Dialysis remained an important mortality risk factor.

Retinoblastoma in the Democratic Republic of Congo: 20-Year Review from a Tertiary Hospital in Kinshasa

Background. To determine clinical profile and management of retinoblastoma among children at Kinshasa in Democratic Republic of Congo. Patients and methods. The medical records of patients with a diagnosis of retinoblastoma seen at the University Hospital of Kinshasa from January 1985 till December 2005 were retrospectively reviewed. Demographic profile, clinical data, modes of treatment and outcome were analysed. Results. A total of 49 children, of whom 40 had adequate data on record were identified as retinoblastoma (28 males and 12 females). Nine cases had bilateral disease. The median age at the first symptoms was 9 months (range, 1 month to 6 years) for unilateral retinoblastoma and 18 months (range, 1 month to 3.5 years) for bilateral retinoblastoma. The median age at the first oncology consultation was 2.4 years (range, 6 months to 6 years) for unilateral retinoblastoma and 2.4years (range, 9 months to 4 years) for bilateral disease. Leukokoria was present in 67.5% of subjects. Seventy-five percent abandoned the treatment. The mortality was 92.5%. Conclusion. In Democratic Republic of Congo, retinoblastoma remains a life threatening disease characterized by late referral to a specialized unit and affordability of chemotherapy; all leading to an extension of the disease and high mortality.

Sensitization Rate and Clinical Profile of Congolese Patients with Rhinitis

In the African continent, the sensitization pattern and clinical profile are unknown in patients with rhinitis/rhinosinusitis attending the outpatient ear, nose, and throat (ENT) clinics. We therefore aimed to analyze the clinical characteristics of rhinitis/rhinosinusitis patients in Democratic Republic of Congo (DRC), classify allergic rhinitis (AR) according to the Allergic Rhinitis and Its Impact on Asthma criteria, and evaluate the sensitization profile and its associated factors. From January to May 2009, 423 patients with rhinitis symptoms attending the Outpatient ENT clinic of the University Hospital and Saint Joseph Hospital of Kinshasa were evaluated for allergy symptoms, severity, and duration of symptoms and underwent skin-prick tests (SPTs) for a panel of 15 allergens. Of 423 patients 35.2% had positive SPT results, with 40.9% showing polysensitization. Dermatophagoides pteronyssinus (DPT) (68.5%) and cockroach (36.2%) were the most common allergens among sensitized patients. Patients with rhinitis/rhinosinusitis mainly presented in decreasing order with sneezing, facial pain/pressure, nasal obstruction, postnasal discharge, nose itching, clear nasal discharge, and eye itching. Persistent and moderate/severe AR represented 61.4 and 69.3%, respectively. Sensitization was independently associated with younger age, rhinoconjunctivitis, and reaction to nonspecific trigger factors. In conclusion, 35.2% of patients attending the ENT Outpatient Clinic in DRC for rhinitis problems had a positive SPT to at least one allergen, with mainly DPT and cockroach allergens being involved; and a substantial portion showed persistent and moderate/severe AR. Therefore, allergy should not be neglected as an etiologic factor in rhinologic disease in the African continent.

Clinical and epidemiological features of rheumatic diseases in patients attending the university hospital in Kinshasa

The aim of the present retrospective and hospital-based study was to describe epidemiological and clinical features of rheumatic diseases in patients attending the University Hospital of Kinshasa (UHK). Rheumatic complaint was a reason for consultation in 12.1% of outpatients attending the Department of Internal Medicine of the UHK. Osteoarthritis was the most common rheumatic disease (59.2%), followed by soft tissue rheumatism (16.1%), gout (9.3%), and spondylarthropathies (7.5%). The cumulative frequency of autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, dermatomyositis, and mixed connective tissues disease) and the frequency of osteoporosis were 5.2 and 2.7%, respectively. Lumbar spine was the part of the skeleton mostly affected by osteoarthritis. Pathological fractures in osteoporosis, subcutaneous nodules, rheumatoid factor, and erosive bone lesions in rheumatoid arthritis were rarely found. Compared to the previous studies performed in the same hospital, our results disclose a threefold increase of rheumatic outpatients. The paucity of erosive arthritis and extra-articular manifestations suggest the less severity of rheumatoid arthritis in our patients. Likewise, the absence of femoral and wrist osteoporotic fractures and the scarcity of advanced vertebral crush fractures suggest the mildness of osteoporosis.

Cancer of the large bowel in the African: A 15-year survey at Kinshasa University Hospital, Zaïre

In a 15-year survey at Kinshasa University Hospital, 954 solid cancers were recorded. Among these, 46 malignant tumours arose in the colon, rectum and anal canal, a proportion of 4-8 per cent. A review of the patients' age and clinical presentation, and pathology and aetiology of the tumours revealed that: 1. The incidence of this cancer in young Africans is higher than in Western countries. 2. The clinical presentation of this illness in young people is frequently unusual, but older African patients commonly present with classic symptoms. 3. The incidence of mucous carcinoma tends to be higher, but could be explained by the larger number of young people suffering from the condition. 4. Intestinal amoebiasis was associated with cancer in 3 cases. Its significance remains uncertain.

Clinicopathologic analysis of carcinoma of the breast in an African population.

A ten-year survey at Kinshasa University Hospital, Zaĭre, has shown that carcinoma of the breast is relatively common and accounts for 23% of all solid cancers in women. In most respects the growth is similar to that seen elsewhere. However, certain features not usually reported were noted: (1) Patients in Zaĭre are, overall, about ten years younger than those seen in western populations. (2) Compared with western data, the disease here is significantly associated with multiparity and breast-feeding. The reasons for these differences are not clear at present.
