INTRODUCTION: Nephrotic syndrome represents a significant part of chronic kidney disease in Black Africa. Our work aimed to determine the frequency and type of kidney lesions in an adult carrying pure nephrotic syndrome. PATIENTS AND METHODS: We conducted a prospective and descriptive study (2003-2004), 40 patients were recruited on the basis of the presence of a pure nephrotic syndrome. Proteinuria was plentiful, selective to albumin greater than 3 g/24h, not accompanied by hematuria, or high blood pressure, or kidney failure. Cases of bacterial, parasitic and viral infections (hepatitis B, C, HIV) were excluded. By following contra-indications of renal biopsy, samples were taken under local anesthesia by means of percutaneous lumbar and fixed in two tubes, one containing "Michel's medium" and the other 12% Formalin. These techniques and readings were carried out in the pathological anatomy Laboratories of Nantes (France) and Conakry (Guinea). RESULTS: There were 24 men and 16 women with an average age of 26.2 ± 8 years [range: 20-51]. Clinical symptoms were dominated by weight gain characterized by edema. Proteinuria was between 3-3.5 g/24h in 16 (40%); between 3.6-5 g in 2 cases (5%) and greater than 5 g/24h in 22 cases (55%). The number of glomeruli was on average 11 ± 9 [range: 3-36]; glomerular permeability was on average 10.4 ± 10. Renal impairment was glomerular in 22 cases, tubulointerstitial in 12 cases and vascular in 6 cases. Immunofixation was positive in 30/40 cases for IgA IgG IgM; in 26 cases for C1q C3; in 4 cases for C1q C3 C4; and finally for fibrin in 28 cases. Histological renal lesions were FSGS (40%), MDC (35%), MGN (5%), MPGN (5%) and undetermined (15%). CONCLUSION: A regular practice of renal anatomopathological examination "on the spot" will lead us to carefully assess the causes of kidney failure associated with nephrotic syndrome.
INTRODUCTION: Le syndrome néphrotique représente une part importante d'insuffisance rénale chronique en Afrique noire. Notre travail avait pour but de déterminer la fréquence et le type de lésions histologiques rénales chez un adulte porteur d'un syndrome néphrotique pur. PATIENTS ET MÉTHODES: Au cours d'une étude prospective et descriptive (20032004), 40 patients ont été sélectionnés sur la base de la présence d'un syndrome néphrotique pur. La protéinurie était abondante, sélective à l'albumine, supérieure à 3 g/24h, non accompagnée d'hématurie, ni d'hypertension artérielle, ni d'insuffisance rénale. Les cas d'infections bactériennes, parasitaires et virales (hépatites B, C, HIV) ont été volontiers exclus. En respectant les contre indications de la biopsie rénale, les prélèvements ont été effectués sous anesthésie locale, par voie lombaire percutanée, puis fixés dans deux tubes dont un contenait du « liquide de Michel ¼ et l'autre du Formol à 12%. Les techniques et lectures ont été effectuées aux Laboratoires d'anatomie pathologique de Conakry (Guinée) et de Nantes (France). RESULTATS: Il s'agissait de 24 hommes et de 16 femmes âgés en moyenne de 26,2 ± 8 ans [2051]. La symptomatologie clinique était dominée par une prise de poids marquée par les Ådèmes. La protéinurie était comprise entre 33,5 g/24h dans 16 cas (40%); entre 3,65 g dans 2 cas (5%) et supérieure à 5 g/24h dans 22 cas (55%). Le nombre de glomérules était en moyenne de 11 ± 9 [336]; la perméabilité des glomérules était en moyenne de 10,4 ± 10. L'atteinte rénale était glomérulaire dans 22 cas, tubulo-interstitielle dans 12 cas et vasculaire dans 6 cas. L' immunofixation a été positive dans 30 cas /40 pour les IgA IgG IgM; dans 26 cas pour C1q C3; dans 4 cas pour C1q C3 C4; et en fin pour la fibrine dans 28 cas. Les lésions histologiques rénales étaient une HSF (40%), une LGM (35%), une GEM (5%), une GNMP (5%) et indéterminée (15%). CONCLUSION: Une pratique régulière de l'examen anatomo-pathologique rénal «sur place" nous amènerait à apprécier judicieusement les causes d'insuffisance rénale en rapport avec un syndrome néphrotique.
RESUMO
The prevalence of the dyslipidemia is higher at the patients in chronic renal failure (CRF) than in the general population. The objective of this study was to determine the prevalence and the lipidic anomalies among uraemic patients and to evaluate the others associated factors of cardiovascular risk. The study was descriptive with prospective recruitment (November 2004-June 2005); concerned 60 patients having an advanced chronic renal failure whose calculated clearance of creatinin was lower than 30 ml/mn as well as the hemodialysed patients. The lipidic disturbances on the whole 9/16 dialysed (56%) and 31 uraermia /44 were not dialysed (70%). This majority triglyceride dyslipidemia comprised 8 cases of hypertriglyceridemia in the group of dialysed patients against 19 in the group of not dialysed; 1 case of mixed hyperlipidemia against 6 cases and 4 cases of hypercholesterolemia HDL in the non dialysed group with 1 case of HDL low cholesterol. The patients with dyslipidemia were 4 females (25%) and 5 males (31%) among dialysed group; and of 13 female (29%) and 18 male (41%) among not dialysed. The average age was of 54.3 +/- 0.7 years for dialysed against the 46.6 +/- 0.2 years for the dyslipidémia in the non dialysed. Among others factors of cardiovascular risk, the arterial high blood pressure was noted at 9 dialysed patient's dyslipidémia and 20 case / 31 to the not dialysed dyslipidémia; and the diabetes was observed in 1 and 3 cases respectively. The addiction to smoking was noted in both groups except at the dialysis patients not dyalipidémiques.

INTRODUCTION: The epidemiological profile of urinary stones varies from region of the world to another according to food habit and certain enviromental factors. The aim of our study was to establish an etiological approach of the urinary lithiasis collected in Conakry by morphological and constitutional analysis. MATERIALS AND METHODS: It was a prospective study from january 1 rst 2003 to january 1 rst 2004 concerning all the stones collected. They were analysed by binocular magnifying glass and infra red spectrophotometry of Fourier. RESULTS: During the period, 18 patients were observed (14 male, 4 femele) of 27.4 +/- 4 years old (from 2 to 69) living mainly in urban environment. From these patients 28 stones were collected; 12 spontaneously and 16 surgicaly. Their composition were whewellite (36%), struvite (29%), carbapatite (14%), urates (14%) and weddellite (7%). In Conakry stones come mainly from hyperoxaluria and urinary tract infection; hypercalciuria is uncomon. CONCLUSION: The urinary calculations examined among patients show in the adult a prevalence of elements in favour of a hyperoxalurie and a notable context of urinary infections in particular in the child; the pure hypercalciurie remains negligible in Conakry, we plan to lead a thorough work to the national scales.

It is a retrospective study of descriptive type on a 4 years period, from April 1, 1999 to March 31, 2003. The aim was to determine factors bound to morbidity and mortality of renal affections in the Conakry University Hospital Center Nephrology Unit. The study was based on 606 hospitalized patients of whom 21 dialysed. The study's references were age, sex, renal affections frequency, mortality, associated pathologies, hospitalization period, death hours and other factors of cardio-vascular risks (tobacco, alcohol). Patients having answered to the selection criteria were 365 men (60.23%) and 241 women (39.77%) with a sex ratio of 1.51. The average age was 44 +/- 17 years old with extremes of 15 and 95 years old; 16.34% of the patients were aged less than 25 years and 14.03% were more than 65 years old. According to the charge taking, 462 (76.24%) were at their neighbors' charge, only 144 (23.76%) could take themselves in charge for their medical care. According to the received treatment before hospitalization, 357 had consumed decoctions of leaves and roots, 86 consulted a health center. The average period of hospitalization was 13 +/- 9 days with extremes of 1 and 80 days. Nicotine addiction was observed with 183 patients of whom 181 were men and alcoholism with 134 patients of whom 122 were men. Renal affections were chronic renal failure (51%), arterial hypertension (30.36%), chronic kidney disease (8.09%), intense renal failure (7.59%), urinary infections (1.65%), intense kidney disease (0.99%) and kidney cancer (0.33%). Among them, 130 deaths were observed (21.45%). According to the period going on before the medical check up, 24 death occurred 2 weeks after the first symptom, and 106 after more than a month. Considering the hours, 33 death (25.38%) occurred between 8 a.m. and 4 p.m. and 63 deaths (48.47%) between 4 p.m. and 8 a.m.; in 34 cases, the hour was not specified. Mortality was due to chronic renal failure in 97 cases (74.61%), to arterial hypertension in 19 cases (14.62%) and to other affections in 14 cases (0.77%). Infections, diabetes, arterial hypertension and anemia sickle cells were renal risk factors. Morbidity and mortality factors were numerous and varied: medical check up delay, traditional cure, patients 'weak turnover, lack of medical care, lack of required equipment and the absence of popular health education.

Il s'agit d'une étude rétrospective de type descriptif sur une période de 4 ans, allant du 01Avril 1999 au 31 Mars 2003. L'objectif était de déterminer les facteurs liés à la morbidité et à la mortalité des affections rénales dans le service de Néphrologie du CHU de Conakry. L'étude a portésur 606 patients hospitalisés dont 21 dialysés. Les paramètres de l'étude étaient l'âge, le sexe, lafréquence des affections rénales, la mortalité, les pathologies associées, le délai de consultation, laprise en charge, le traitement reçu avant l'hospitalisation, la durée d'hospitalisation, les horaires de décès et certains facteurs de risque cardio-vasculaires (tabac, alcool). Les malades ayant réponduaux critères de sélection étaient 365 hommes (60,23%) et 241 femmes (39,77%) avec un sex-ratio de1,51. La moyenne d'âge était de 44 ± 17 ans avec des extrêmes de 15 et 95 ans ; 16,34% des patients étaient âgés de moins de 25 ans et 14,03% avaient plus de 65 ans. Selon la prise en charge, 462 (76,24%) étaient à la charge de leur entourage, seuls 144 (23,76%) pouvaient se prendre en charge pour les soins. Selon le traitement reçu avant l'hospitalisation, 357 avaient consommé des décoctions de feuilles et de racines, 86 avaient consulté un centre de santé. La durée moyenne d'hospitalisation a été de 13 ± 9 jours avec des extrêmes de 1 et 80 jours. Le tabagisme avait été observé chez 183 malades dont 181 hommes et l'alcoolisme chez 134 malades dont 122 hommes. Les affections rénales étaient l'insuffisance rénale chronique (51%), l'hypertension artérielle (30,36%), les glomérulonéphrites chroniques (8,09%), l'insuffisance rénale aiguë (7,59%), les infections urinaires (1,65%) les glomérulonéphrites aiguës (0,99%) et le cancer du rein (0,33%). Parmi eux, 130 décès avaient été observés soit 21,45%. Selon le délai écoulé avant la consultation, 24 décès étaient survenus 2 semaines après le premier symptôme et 106 après plus d'un mois.Suivant les horaires, 33 décès (25,38%) étaient survenus entre 8h et 16h et 63 décès (48,47%) entre 16h et 8h ; dans 34 cas, l'heure n'était pas précisée. La mortalité était due à l'insuffisance rénale chronique dans 97 cas, soit 74,61%, à l'hypertension artérielle dans 19 cas, soit 14,62% et aux autres affections dans 14 cas, soit 0,77%. Les infections, le diabète, l'hypertension artérielle et la drépanocytose étaient les facteurs de risque rénal. Les facteurs de morbidité et de mortalité étaient nombreux et variés à savoir : le retard à la consultation, le traitement traditionnel, le faiblerevenu des malades, l'absence de couverture sanitaire, le manque de prise en charge correct au cours des gardes, le manque d'équipement adéquat et l'absence d'éducation sanitaire populaire

For a long time endocrine pathology was unrecognized or even denied to exist in Black Africans, but this is not true. It seems to be recognized more frequently since medicalization has increased. This pathology does not present any particularities. Hyperthyroidism appears frequently, at least in urban areas. A series of 87 personal cases has permitted a review of the principal clinical and biological aspects; myasthenia seems to be particularly important; radical treatment is preferred over prolonged medical treatment which is not within the financial possibilities of our patients. There have been 30 observations of cortico-adrenal anomalies of which 7 known personally. It must be noted that the Black living in his traditional rural environment presents a certain degree of physiological hypocorticism with respect to whites and especially Blacks of higher social standing. Pathological hypocorticism is essentially due to tuberculosis; the melanodermia is evident to an alert observer. Metabolic hypercorticism produces the usual manifestations. Only 9 cases of Sheehan syndrome have been reported (5 personal). In the Black African woman, it appears earlier than in Europe often due to premature nuptiulity and the higher incidence of tachyparity. One is surprised that this syndrome is detected so rarely; it is, without a doubt, often well tolerated during a long period of time therefore goes undetected.
