Dietary salt intake and kidney function in rural Senegalese populations: a cross-sectional study.

INTRODUCTION: High salt intake is a major risk factor for hypertension and its complications such as chronic kidney disease (CKD) and cardiovascular diseases. The present study aimed to determine level of sodium consumption and its relation with kidney function in the rural populations of Ferlo (centre of Senegal). SUBJECTS AND METHODS: We performed a cross-sectional study including 400 volunteers aged > 18 years. Clinical, biological and dietary data were collected during household visits. Daily sodium intake was measured in the 24 h-urine outpout and CKD was defined as eGFR < 60 ml/min. Linear regression analysis was used to assess association between sodium intake and covariates. RESULTS: Mean age was 46.42 ± 15.60 and sex-ratio was 1.05. Prevalence of hypertension, CKD and overweight were 21.5, 11.7 and 20.5%, respectively. The median daily salt intake was 11.7 g with interquartile range of 14.8 g. Only 11.25% of participants consumed less than 5 g/day. After multivariate analysis, high salt intake was associated with age > 60 years, overweight and CKD. However, gender and hypertension were not significantly associated with salt intake. Industrial broths (91.5%) and bread (85%) represented the main sources of dietary salt. CONCLUSION: This study revealed high levels of daily salt intake contrasting with low potassium intakes in the majority of participants. Participants with CKD, overweight and age > 60 years presented higher salt consumption. Stategies to reduce salt consumption are urgently needed to reduce burden of CKD in rural Senegalese populations.

[Megaesophagus revealed by pleurisy]. / Méga-œsophage révélé par une pleurésie.

We report the case of a 65-year old patient without a history of alcohol consumption and cigarette smoking but with a history of gastrœsophageal reflux disease for which he had never been examined. He was admitted to the Department of Pneumology for exploration of a dry hacking cough causing insomnia associated with diffuse heaviness in his right chest evolving over a month in a context of evening and night fever without weight loss. Clinical and radiological examination showed right pleural effusion syndrome. Radiographic follow-up after evacuating pleural effusion by puncture showed inhomogeneous opacity occupying nearly all the right lung (A). Chest CT scan objectified thoracic megaesophagus associated with non-specific pleuro-pulmonary disease. The patient underwent upper gastrointestinal endoscopy that didn't show suspect cancer signs. Pleuro-pulmonary disease outcome was favorable after amoxicillin treatment.
