[Perception of the cancer diagnosis announcement in a university hospital setting in Ivory Coast: About 120 patients followed in oncology and onco-hematology services]. / Perception de l'annonce du diagnostic de cancer dans un cadre hospitalo-universitaire en Côte d'Ivoire. À propos de 120 patients suivis dans les services d'oncologie et d'onco-hématologie.

BACKGROUND: The diagnostic of cancer is generally associated with a psychological shock. Body's defense mechanisms and drugs cannot resolve emotional distress and symptoms of cancer. A need for psychosocial management of the African patient is necessary. OBJECTIF: Study of perception of the cancer diagnosis announcement by Ivory Coast patients suffering of cancer. PATIENTS AND METHODS: This is a bicenter retrospective and cross-sectional study which aims at describing data over a period of seven (7) months (November 2017 to May 2018). This study took place in the haematology and oncology departments respectively in CHU of Yopougon and Treichville. Patient recruitment was carried out exhaustively. The data was collected using a standardized questionnaire, developed in the french language, which was given individually under the direction of the oncopsychiatrist investigator. The investigation required the presence of an interpreter for patients who did not speak French. This study exhibits sociodemographic, clinical, therapeutical and medico-psychosocial data. So, 120 patients were included. RESULTS: Breast's cancer was frequent (61%) and found at advanced stages (71%). Incurability and death's idea were 0.8% and 3.3%, respectively. Diagnostic announcement was good in 95% cases, but patients developed sadness (63.3%), denial (10%) and idea of suicide (3.4%). The psychosocial life of patients was affected by depressed state (35%). The therapeutical route was marked by medical treatment (42%), religious (41%), herbal treatment (9%). Altogether, 68.3% of patients had a social support, either given by friends (47.6%) or were financially supported (36.6 %) . CONCLUSION: This study was oriented towards formalization or integration of a psycho-oncological intervention during the management of a black patient group suffering from various cancers.

[Pre-therapeutic and evolutive characteristics of patients suffering from chronic myeloid leukemia, in Abidjan, Ivory Coast]. / Caractéristiques préthérapeutiques et évolutives des patients atteints de la leucémie myéloïde chronique à Abidjan Côte d'Ivoire.

INTRODUCTION: The diagnosis of chronic myeloid leukemia is based on the presence of translocation t(9,22). Additional cytogenetic abnormalities may exist at diagnosis and have prognostic value. The authors evaluated the relationship between these additional chromosomal abnormalities, clinical presentation, and therapeutic response. METHOD: In a retrospective and comparative study from 2005 to 2015, at Yopougon university hospital, 51 cases of myeloid leukemia were selected, including 22 cases with additional chromosomal abnormalities. RESULTS: Thirteen types of additional Ph1 abnormalities were detected in one group, with a median age of 39years (13-73); a sex ratio of 1.4 and a low social class (49%). The median consultation time is 13months (2-29). Hepatomegaly (54%, P=0.05); fever (81.8%, P=0.0017); bone pain (63.6%, P=0.0001); lymphadenopathies (27.3% P=0.014); poor general condition [WHO>1 (77.3%, P=0.001)], high Sokal index (63.6%, P=0.0019), eosinophilia>5% (72.7, P=0.02) and circulating blastosis were found more frequent in the group with additional abnormalities treated with imatinib mesylate. We obtained 13.6% hematologic remission and 22.7% cytogenetic remission (P=0.02). The average survival was relatively short (20months vs. 76.4months, Log-rank<0.0001). We deplored a high death rate (59.1%). CONCLUSION: The presence of an additional anomaly constitutes a pejorative element refractory to imatinib.

[Retrospective study about 20 cases of ovarian Burkitt lymphoma at Yopougon teaching hospital in Côte d'Ivoire]. / Étude rétrospective rapportant 20 cas de lymphome de Burkitt de localisation ovarienne pris en charge au CHU de Yopougon en Côte d'Ivoire.

CONTEXT: The maxillo-facial attack was the first described in the Burkitt lymphoma in 1958 by Denis Pearsons Burkitt. Abdominopelvic disorders, particularly ovarian localization are observed more and more by the developments of imagery technics. Our study aimed to describe the epidemiologic, clinical, therapeutic and evolutive aspects of ovarian localization in the endemic Burkitt lymphoma. METHODOLOGY: Twenty files of ovarian Burkitt lymphoma diagnosed in the clinical service of hematology TH of Yopougon during the period August 1995-March 2015 (19 years) were retrospectively analyzed. The epidemiologic, clinical, therapeutic and evolutive parameters were studied. RESULTS: Ovarian Burkitt lymphoma accounted for 20.41% of the population with Burkitt lymphoma and 38.46% for patients with Burkitt lymphoma. The average age was 20.4 years with extremes of 6 and 38 years. The main reasons for consultation were general impairment (85%) and pelvic mass (80%). 75% were in group B clinical scalability. The ovarian mass was bilateral in 60% of cases, heterogeneous in 75% of cases. There was a clear predominance of stage III of Murphy (55%). On the evolutionary level all the patients treated by chemotherapy were in incomplete remission (100%). 10% were alive. 83.33% of the deceased patients had received less than 6 courses of chemotherapy. CONCLUSION: The diagnosis of ovarian endemic Burkitt lymphoma is most often delayed diagnosis and poor prognosis. Improving its management requires early diagnosis.

Prevalence and correlates of growth failure in young African patients with sickle cell disease.

Growth failure (GF) in children with sickle cell disease (SCD) tends to decline in high-income countries, but data are lacking in sub-Saharan Africa. We performed a cross-sectional study nested in the CADRE (Cœur, Artères et DREpanocytose) cohort in Mali, Senegal, Cameroon, Gabon and the Ivory Coast. SCD patients and healthy controls aged 5-21 years old were recruited (n = 2583). Frequency of GF, defined as a height, weight or body mass index below the 5th percentile on World health Organization growth charts, was calculated. We assessed associations between GF and SCD phenotypic group, clinical and biological characteristics and history of SCD-related complications. GF was diagnosed in 51% of HbSS, 58% of HbSß0 , 44% of HbSC, 38% of HbSß+ patients and 32% of controls. GF in patients was positively associated with parents' lower education level, male sex, age 12-14 years, lower blood pressure, HbSS or HbSß0 phenotypes, icterus, lower haemoglobin level, higher leucocyte count and microalbuminuria. No association was found between GF and clinical SCD-related complications. In sub-Saharan Africa, GF is still frequent in children with SCD, especially in males and during adolescence. GF is associated with haemolysis and microalbuminuria, but not with the history of SCD-related clinical complications.

Subclinical Cardiac Dysfunction Is Associated With Extracardiac Organ Damages.

Background: Several studies conducted in America or Europe have described major cardiac remodeling and diastolic dysfunction in patients with sickle cell disease (SCD). We aimed at assessing cardiac involvement in SCD in sub-Saharan Africa where SCD is the most prevalent. Methods: In Cameroon, Mali and Senegal, SCD patients and healthy controls of the CADRE study underwent transthoracic echocardiography if aged ≥10 years. The comparison of clinical and echocardiographic features between patients and controls, and the associations between echocardiographic features and the vascular complications of SCD were assessed. Results: 612 SCD patients (483 SS or Sß0, 99 SC, and 19 Sß+) and 149 controls were included. The prevalence of dyspnea and congestive heart failure was low and did not differ significantly between patients and controls. While left ventricular ejection fraction did not differ between controls and patients, left and right cardiac chambers were homogeneously more dilated and hypertrophic in patients compared to controls and systemic vascular resistances were lower (p < 0.001 for all comparisons). Three hundred and forty nine SCD patients had extra-cardiac organ damages (stroke, leg ulcer, priapism, microalbuminuria or osteonecrosis). Increased left ventricular mass index, cardiac dilatation, cardiac output, and decreased systemic vascular resistances were associated with a history of at least one SCD-related organ damage after adjustment for confounders. Conclusions: Cardiac dilatation, cardiac output, left ventricular hypertrophy, and systemic vascular resistance are associated with extracardiac SCD complications in patients from sub-Saharan Africa despite a low prevalence of clinical heart failure. The prognostic value of cardiac subclinical involvement in SCD patients deserves further studies.

Degree of anemia, indirect markers of hemolysis, and vascular complications of sickle cell disease in Africa.

The hyperhemolysis paradigm that describes overlapping "hyperhemolytic-endothelial dysfunction" and "high hemoglobin-hyperviscous" subphenotypes of sickle cell disease (SCD) patients is based on North American studies. We performed a transversal study nested in the CADRE cohort to analyze the association between steady-state hemolysis and vascular complications of SCD among sub-Saharan African patients. In Mali, Cameroon, and Ivory Coast, 2407 SCD patients (1751 SS or sickle ß-zero-thalassemia [Sß0], 495 SC, and 161 sickle ß+-thalassemia [Sß+]), aged 3 years old and over, were included at steady state. Relative hemolytic intensity was estimated from a composite index derived from principal component analysis, which included bilirubin levels or clinical icterus, and lactate dehydrogenase levels. We assessed vascular complications (elevated tricuspid regurgitant jet velocity [TRV], microalbuminuria, leg ulcers, priapism, stroke, and osteonecrosis) by clinical examination, laboratory tests, and echocardiography. After adjustment for age, sex, country, and SCD phenotype, a low hemoglobin level was significantly associated with TRV and microalbuminuria in the whole population and with leg ulcers in SS-Sß0 adults. A high hemolysis index was associated with microalbuminuria in the whole population and with elevated TRV, microalbuminuria, and leg ulcers in SS-Sß0 adults, but these associations were no longer significant after adjustment for hemoglobin level. In conclusion, severe anemia at steady state in SCD patients living in West and Central Africa is associated with elevated TRV, microalbuminuria, and leg ulcers, but these vascular complications are not independently associated with indirect markers of increased hemolysis. Other mechanisms leading to anemia, including malnutrition and infectious diseases, may also play a role in the development of SCD vasculopathy.

Arterial Stiffness Impairment in Sickle Cell Disease Associated With Chronic Vascular Complications: The Multinational African CADRE Study.

BACKGROUND: Although a blood genetic disease, sickle cell disease (SCD) leads to a chronic vasculopathy with multiple organ involvement. We assessed arterial stiffness in SCD patients and looked for associations between arterial stiffness and SCD-related vascular complications. METHODS: The CADRE (Coeur Artères et Drepanocytose, ie, Heart Arteries and Sickle Cell Disease) study prospectively recruited pediatric and adult SCD patients and healthy controls in Cameroon, Ivory Coast, Gabon, Mali, and Senegal. Patients underwent clinical examination, routine laboratory tests (complete blood count, serum creatinine level), urine albumin/creatinine ratio measure, and a measure of carotid-femoral pulse wave velocity (cf-PWV) and augmentation index (AI) at a steady state. The clinical and biological correlates of cf-PWV and AI were investigated by using a multivariable multilevel linear regression analysis with individuals nested in families further nested in countries. RESULTS: Included were 3627 patients with SCD and 943 controls. Mean cf-PWV was lower in SCD patients (7.5±2.0 m/s) than in controls (9.1±2.4 m/s, P<0.0001), and lower in SS-Sß(0) than in SC-Sß(+) phenotypes. AI, corrected for heart rate, increased more rapidly with age in SCD patients and was higher in SCD than in control adults. cf-PWV and AI were independently associated with age, sex, height, heart rate, mean blood pressure, hemoglobin level, country, and hemoglobin phenotype. After adjustment for these correlates, cf-PWV and AI were associated with the glomerular filtration rate and osteonecrosis. AI was also associated with stroke, pulmonary hypertension, and priapism, and cf-PWV was associated with microalbuminuria. CONCLUSIONS: PWV and AI are deeply modified in SCD patients in comparison with healthy controls. These changes are independently associated with a lower blood pressure and a higher heart rate but also with the hemoglobin phenotype. Moreover, PWV and AI are associated with several SCD clinical complications. Their prognostic value will be assessed at follow-up of the patients.

Early renal damage in patients with sickle cell disease in sub-Saharan Africa: a multinational, prospective, cross-sectional study.

BACKGROUND: Chronic kidney disease is one of the leading causes of mortality in patients with sickle cell disease. However, it has been almost exclusively studied in patients with the SS phenotype and in high-income countries, despite more than 80% of patients living in Africa. We looked for the determinants of glomerulopathy in a multinational cohort of patients with sickle cell disease of different phenotypes in sub-Saharan Africa. METHODS: In the CADRE cohort, we prospectively included patients 3 years and older with sickle cell disease of all haemoglobin phenotypes in Cameroon, Côte d'Ivoire, Mali, and Senegal. All individuals were assessed at steady state. The main outcome of interest was albuminuria defined as a urine albumin-to-creatinine ratio of greater than 30 mg/g. We investigated the clinical and biological determinants (including haemolysis markers) of albuminuria in two main phenotype groups (SS and Sß(0); SC and Sß(+)) with further stratification by age and country. FINDINGS: The study is ongoing because of follow-up. 2582 patients with sickle cell disease were included (1776 SS, 136 Sß(0), 511 SC, and 159 Sß(+)). 644 patients with the SS and Sß(0) phenotypes (33·7%, 95% CI 31·6-35·8) and 110 with the SC and Sß(+) phenotypes (16·4%, 13·6-19·2) had albuminuria. In the SS and Sß(0) group, albuminuria was detected in 144 (27%) of 527 children younger than 10 years and its frequency increased with age (29 [48%] of 60 patients aged >40 years). Multivariable analysis showed that albuminuria was associated with age (odds ratio 1·43, 95% CI 1·20-1·71; p<0·0001), female sex (1·35, 1·02-1·82; p=0·045), low haemoglobin (0·79, 0·66-0·93; p=0·006), high lactate dehydrogenase concentrations (1·33, 1·14-1·58; p=0·0009), and, using Côte d'Ivoire as the reference, Mali (2·49, 1·64-3·79; p=0·042) and Cameroon (1·59, 1·01-2·51; p=0·0007) in patients with the SS and Sß(0) phenotypes. The magnitude of the association of albuminuria with haemoglobin and lactate dehydrogenase concentrations increased with age. In the SC and Sß(+) patients, only low haemoglobin (0·69, 0·48-0·97; p=0·029), high blood pressure (1·63, 1·17-2·27; p=0·0017), and Mali (3·75, 1·75-8·04; p<0·0001) were associated with albuminuria. INTERPRETATION: Hyperhaemolysis is associated with albuminuria, with an age-dependent effect, in the SS and Sß(0) phenotypes only, suggesting a different pathological mechanism for glomerular disease in the patients with SC and Sß(+) phenotypes. However, both phenotypes are associated with a high prevalence of albuminuria in childhood. Therefore, screening for albuminuria is advised in African children with sickle cell disease to detect early renal damage.

Characteristics and Results of the Treatment of Multiple Myeloma in the Subject under the Age of 65 at the University Hospital of Yopougon in Abidjan, Côte d'Ivoire.

We retrospectively studied 30 cases of multiple myeloma in patients under the age of 65, diagnosed from 1991 to 2005 in the clinical hematology department of the University Hospital of Yopougon that is a hospital incidence of 2.9 cases/year. The age of patients ranged from 34 to 64 years, with a mean age of 49 years and a sex ratio of 1.73. The professional activity was variable with 3% of radiographers and 10% of farmers. Clinically, the dominant sign was bone pain in 83% of cases. Myeloma was secretory in 93% of cases. It was Ig G-type in 86%, kappa-type in 66% of cases. 86% of patients were anemic, 20% had creatinine >20 mg/L, and 10% had serum calcium >120 mg/L. Geodes were found in 80% of cases. 53% were at stage III of DURIE and SALMON. Complications were infectious (33%), renal (20%), and hemorrhagic (7%). Chemotherapy regimens were VAD (10%), VMCP (30%), and VMCP/VBAP (60%) with 47% of partial responses, 33% of stable disease, and 7% of very good quality partial responses. The outcome developed towards death in 37% and causes of death were renal in 46% of cases. The median survival was only 5.1 months.
