Impact of renal failure on survival of African patients with cirrhosis.

To assess the effect of renal failure on the survival of black African patients with cirrhosis, we studied 132 (82 males, 50 females) cirrhotic black African patients with mean age of 47.5+/-14.4 years and mean follow-up period of 373+/-194 days. The edema and ascitis were the main reasons for admission to hospital. Renal failure was present in 30 (22.7%) patients, and it was positively correlated to the severity of the stage of the liver disease, and associated with severe hyponatremia. Survival at 1 year was 60.1% and 37.6% in the absence or presence of renal failure, respectively (p<0.001)). The stage of the liver disease was significantly inversely correlated with survival, which was further diminished in the presence of renal failure:23.7% versus 12.5% for Child-Pugh-Turcote (CPT) A-B in the absence or presence of renal failure, respectively (p=0.67), 30.2% versus 81.8% for CPT C in the absence or the presence of renal failure respectively (p<0.001). Hyponatremia has also appeared detrimental to survival, since mortality was 38.4% versus 81.8% in the absence or the presence of hyponatremia respectively (p<0.001). By multivariate analysis, renal failure, CPT stage C, and hyponatremia independently significantly correlated to mortality in patients with cirrhosis. We conclude that renal failure is frequently associated with decompensated cirrhosis. The presence of renal failure in this setting often results in high mortality. Renal failure that occurs in the setting of a severe liver disease and hyponatremia may be part of hepatorenal syndrome.

Child-Pugh-Turcott versus Meld score for predicting survival in a retrospective cohort of black African cirrhotic patients.

AIM: To compare the performance of the Child-Pugh-Turcott (CPT) score to that of the model for end-stage liver disease (MELD) score in predicting survival of a retrospective cohort of 172 Black African patients with cirrhosis on a short and mid-term basis. METHODS: Univariate and multivariate (Cox model) analyses were used to identify factors related to mortality. Relationship between the two scores was appreciated by calculating the correlation coefficient. The Kaplan Meier method and the log rank test were used to elaborate and compare survival respectively. The Areas Under the Curves were used to compare the performance between scores at 3, 6 and 12 mo. RESULTS: The study population comprised 172 patients, of which 68.9% were male. The mean age of the patient was 47.5 +/- 13 years. Hepatitis B virus infection was the cause of cirrhosis in 70% of the cases. The overall mortality was 31.4% over 11 years of follow up. Independent factors significantly associated with mortality were: CPT score (HR = 3.3, 95% CI [1.7-6.2]) (P < 0.001) (stage C vs stage A-B); Serum creatine (HR = 2.5, 95% CI [1.4-4.3]) (P = 0.001) (Serum creatine > 1.5 mg/dL versus serum creatine < 1.5 mg/dL); MELD score (HR = 2.9, 95% CI [1.63-5.21]) (P < 0.001) (MELD > 21 vs MELD < 21). The area under the curves (AUC) that predict survival was 0.72 and 0.75 at 3 mo (P = 0.68), 0.64 and 0.62 at 6 mo (P = 0.67), 0.69 and 0.64 at 12 mo (P = 0.38) respectively for the CPT score and the MELD score. CONCLUSION: The CPT score displays the same prognostic significance as does the MELD score in black African patients with cirrhosis. Moreover, its handling appears less cumbersome in clinical practice as compared to the latter.

[Clinical, endoscopic and histologic aspects of chronic Helicobacter pylori gastritis in Côte d'Ivoire: study of 102 patients]. / Aspects cliniques, endoscopiques et histologiques des gastrites chroniques à Helicobacter pylori en Côte d'Ivoire: étude de 102 patients.

BACKGROUND: Helicobacter pylori (H. pylori) is the most frequent aetiological factor of chronic gastritis (CG). The relationship between H. pylori gastritis, gastro-duodenal ulcer and some gastric cancers (adenocarcinoma, gastric MALT lymphoma) has now been proven. AIM: Describe clinical, endoscopical and histological aspects of H. pylori gastritis in Côte d'Ivoire. METHODS: Retrospective analysis of 1960 gastroscopy reports carry out between January 1994 and December 1995. Analysis of clinical and gastric histological results in 137 patients. FINDINGS: Among 137 patients with gastric biopsy, 102 had H. pylori gastritis (68 men, 38 women, mean age: 39.3 years) and 35 had chemical gastritis. Epigastric pain was the most frequent symptom. The mucosa was frequently erythematous or exsudative at endoscopy. Histological anomalies were located in the antrum, the fundus or generalised, respectively in 33.3%, 25.5% and 41.2% of cases. Mild atrophic CG was more frequent in various locations. Gastritis activity was present in 81.4%, intestinal metaplasia in 18.6% and follicular lymphoid hyperplasia in 36.3% of cases. CONCLUSION: Clinical and endoscopical aspects of H. pylori gastritis did not present any particularities. Fundic gastritis without antral localisation was not unusual. This situation could be the result of antibiotic and gastric acid secretion inhibitor treatments.
