Suivi post-greffe rénale à Kinshasa : analyse de survie et des facteurs associés à la perte de la fonction rénale du greffon

Contexte et objectifs. La greffe rénale n?est pas encore pratiquée en RDC, ce qui oblige les patients à se faire opérer à l?étranger. Le suivi post-greffe est fait localement par des médecins congolais, mais n?a pas encore été évalué. Nos objectifs étaient de déterminer la survie des greffons et d?identifier les facteurs associés à la perte de la fonction rénale du greffon chez les patients suivis à Kinshasa.Méthodes. Nous avons colligé les dossiers des patients qui ont bénéficié d?une greffe rénale à l?étranger (86% en Inde) et dont le suivi post-greffe a été effectué dans les hôpitaux de Kinshasa entre 2000 et 2017. Les paramètres d?intérêt étaient : l?âge au moment de la greffe, le type de greffe, la spécialité du médecin qui avait sélectionné le donneur et qui a fait le suivi post-greffe à Kinshasa, la régularité de prise des immunosuppresseurs et l?issue de la greffe (complications, rejet ou non, reprise ou non en dialyse). Les facteurs associés à la perte de la fonction rénale du greffon (défini par le rejet, une néphropathie chronique du greffon ou la reprise en dialyse) étaient recherchés en analyse univariée. La survie des greffons a été décrite par la méthode de Kaplan-Meier.Résultats. Au total, 29 sujets (moyenne d?âge à la greffe : 48±15 ans ; 83% d?hommes) ont été ou sont suivis en post-greffe rénale à Kinshasa. La greffe avec donneur vivant a été majoritaire (97%), avec 7% de donation ABO différent.Le rejet a été diagnostiqué dans 24% des cas. Les autres complications rapportées étaient : la néphropathie chronique du greffon (24%), les complications urologiques ou vasculaires per-opératoires (3%), la nécrose tubulaire aiguë transitoire (7%), les cancers (10%), le diabète cortisonique (7%) et la réactivation d?une infection par le VHC (3%). 0nze patients (38%) ont été repris en dialyse. La prise irrégulière des immunosuppresseurs (0R :3,33 ; IC 95% : 1,71-6,49 ; p=0,002) et le suivi par un médecin non néphrologue (OR: 2,88 ; IC 95% : 1,64-5,03 ; p=0,004) étaient les deux facteurs associés à la perte de la fonction rénale du greffon. La survie moyenne des greffons était de 61 mois dans le groupe entier, meilleure lorsque la préparation/le suivi était fait par un néphrologue (83 mois vs 41 mois ; p=0,026).Conclusion. Nonobstant un faible échantillonnage, ces donnent révèlent une moins bonne survie des greffons après la transplantation rénale chez les patients suivis à Kinshasa, notamment lorsque la prise en charge n?est pas faite en milieu spécialisé. Une prise de conscience collective et la nécessité d?établir des normes et de bien préparer les patients s?imposent

Prevalence and predictors of metabolic syndrome among Congolese pre- and postmenopausal women.

OBJECTIVES: This study aimed to determine the prevalence and predictors of metabolic syndrome (MetS) among Congolese pre- and postmenopausal women. METHODS: In total, 200 women (100 premenopausal and 100 postmenopausal) were interviewed and underwent clinical and biological investigations searching for lipid and non-lipid cardiovascular risk factors. National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII) criteria were used to define MetS. Multivariate logistic regression analysis was used to evaluate predictors of MetS. RESULTS: There were significant differences between the two groups in terms of age, plasma cholesterol, high density lipoprotein cholesterol and triglyceride levels. MetS was present in 20% and 10% of postmenopausal and premenopausal women (p = 0.07), respectively. The MetS components hypertension, elevated plasma glucose and triglycerides were more frequently observed in post- vs. premenopausal women with MetS. Menopause (adjusted odds ratio (aOR) 2.49; 95% confidence interval (CI) 1.05-5.95), overweight (aOR 6.35; 95% CI 1.66-24.23) and obesity (aOR 14.29; 95% CI: 3.84-53.06) emerged as the main independent predictors of MetS. CONCLUSION: This study showed that MetS is common among Congolese postmenopausal women; menopause and weight gain emerged as its main predictors. This suggests that an integrated therapeutic approach combining hormone replacement therapy and lifestyle change in postmenopausal women should be considered.

Incidence of stroke subtypes, prognosis and prevalence of risk factors in Joinville, Brazil: a 2 year community based study.

BACKGROUND: There have been few population based studies on stroke risk factors and prognosis conducted in Brazil. The objective of this study was to evaluate, over a 2 year period, the incidence of the subtypes of first ever stroke, the prevalence of cardiovascular risk factors and functional prognosis in a city located in the south of Brazil. METHODS: The period from January 2005 to December 2006 was evaluated prospectively by compiling data on first ever stroke cases, medications used prior to the morbidity and the incidence of traditional risk factors. The annual incidence was adjusted for age using the direct method. Patients were monitored for at least 6 months following the event. RESULTS: Of 1323 stroke cases, 759 were first ever stroke cases. Of these, 610 were classified as infarctions, 94 as intracerebral haemorrhage and 55 as subarachnoid haemorrhage. The crude incidence rate per 100 000 inhabitants was 61.8 for infarction (95% CI 57.0 to 66.9), 9.5 for intracerebral haemorrhage (95% CI 7.7 to 11.6) and 5.6 for subarachnoid haemorrhage (95% CI 4.2 to 7.3). The 30 day case fatality was 19.1%. The most prevalent cardiovascular risk factor was arterial hypertension. By post-stroke month 6, 25% had died (95% CI 21.4 to 29.1) whereas 61.5% had regained their independence (95% CI 56.2 to 68.3). CONCLUSIONS: Case fatality rate, prognosis and incidence adjusted for stroke subtypes were similar to those found in other population based studies. The prevalence rates of ischaemic heart disease, dyslipidaemia, arterial hypertension and diabetes suggest that Joinville presents a mixed pattern of cardiovascular risk, a pattern seen in developed and developing countries alike.

Trends in stroke incidence, mortality and case fatality rates in Joinville, Brazil: 1995-2006.

BACKGROUND: Studying stroke rates in a whole community is a rational way to assess the quality of patient care and primary prevention. However, there are few studies of trends in stroke rates worldwide and none in Brazil. OBJECTIVE: Established study methods were used to define the rates for first ever stroke in a defined population in Brazil compared with similar data obtained and published in 1995. METHODS: All stroke cases occurring in the city of Joinville during 2005-2006 were prospectively ascertained. Crude incidence and mortality rates were determined, and age adjusted rates and 30 day case fatality were calculated and compared with the 1995 data. RESULTS: Of the 1323 stroke cases registered, 759 were first ever strokes. The incidence rate per 100 000 was 105.4 (95% CI 98.0 to 113.2), mortality rate was 23.9 (95% CI 20.4 to 27.8) and the 30 day case fatality was 19.1%. Compared with the 1995 data, we found that the incidence had decreased by 27%, mortality decreased by 37% and the 30 day case fatality decreased by 28%. CONCLUSIONS: Using defined criteria we showed that in an industrial southern Brazilian city, stroke rates are similar to those from developed countries. A significant decrease in stroke rates over the past decade was also found, suggesting an improvement in primary prevention and inpatient care of stroke patients in Joinville.

Characteristics of geriatric patients related to early and late readmissions to hospital.

The aim of the study was to evaluate which characteristics of geriatric patients account for readmission to hospital, 6 months after discharge. All patients (203 females, 176 males) consecutively admitted over a two-month period to four acute geriatric care units, located in the cities of Chieti, Perugia, Pescara and Prato, participated in the study. Data that could potentially explain early and late readmissions were collected for each patient. Prevalence of diseases and comorbidity were assessed with the Cumulative Illness Rating Scale (CIRS); physical function by self-report (ADL, IADL) and objective (Stand and Walking Speed) measures; cognitive level by MMSE; and depressive symptoms by the Geriatric Depression Scale (GDS). Information on family and social support were also obtained. After discharge, data on hospital readmissions were collected for six months. For each readmitted patient (cases), medical records were reviewed, and supplementary information was obtained from families and general practitioners. Readmissions were classified as "early" (within the first three months), "late" (within the third and sixth month), and "multiple" (2 or more readmissions irrespective of the period). Patients not readmitted (alive at home) were considered as controls. Systematic differences between centers and between periods of readmissions were evaluated using one-way analyses of variance, and Pearson's chi 2 test. Factors related to early, late, and multiple readmission were identified in multivariate logistic regression models. On univariate analysis, patients readmitted over the first three-month period were sicker than controls (CIRS classes 3-4: 52.1% vs 34.1%), had more social problems or behavioral symptoms, and were more functionally impaired (ADL dependencies 3.3 +/- 0.4 vs 2.1 +/- 0.2). Patients who were readmitted between the third and the sixth month after discharge had a significantly higher CIRS total score (p = 0.006). Patients with multiple readmissions had more severe diseases, and more social problems. On multivariate analysis, early readmission was associated with unsatisfactory social conditions, living alone, severity of diseases and cognitive impairment, while late readmission was associated with comorbidity only. Multiple readmissions were related only to social factors, and to hospital admission before the baseline evaluation. The findings of this study suggest that interventions aimed at improving unfavorable social conditions may reduce the rate of rehospitalization in geriatric patients.

[Epidemiology of cerebrovascular disease in Joinville, Brazil. An institutional study]. / Epidemiologia dos acidentes cerebrovasculares em Joinville, Brasil. Estudo Institucional.

The paucity of epidemiologic data, and the previous impression of high incidence of cerebrovascular disease in Brazil, made us elaborate a prospective institutional study in Joinville, Brazil, with objective of identifying first and recurrent episodes in stroke. This study occurred from March 1995 to March 1996. We evaluated during the first episode of stroke: incidence, mortality and fatality-case ráte (in 30 days lethality), frequency of risk factor, time in hospital and distribution of cerebral infarcts by pathological subtypes. In this period, 429 patients with stroke were registered, 320 with the first episode. 98% of all the patients were submited to at least one computed tomography scanning. The episodes of cerebral infarcts were divided in pathological sub-types. Results showed that the annual incidence adjusted to the age of first stroke episode was 156/100,000. The distribution by diagnosis was: 73.4% for cerebral infarct, 18.4% for cerebral hemorrhage and 7.5% for subarachnoid hemorrhage. The annual standard mortality rate was 25/100,000. The fatality case global rate in 30 days was 26%. Hypertension, previous stroke and diabetes were the most frequent risk factors. Only 25% of the patients were assisted within three hours of the onset of stroke. We concluded that the incidence rate of first episode of stroke is high in institutionalized patient in Joinville, Brazil. The mortality and fatality--case rates are similar to the ones of other populations.
