Bacteriological Profile of Pneumopathies in Chronic Renal Failure at the University Hospital Center of Point-G in Mali

Abstract

Introduction: Chronic renal failure (CKD) is defined as a glomerular filtration rate (GFR) of less than 60 ml/min/1.73m2 for more than 3 months [1]. Infectious complications are a major source of morbidity in patients with chronic renal failure. In Mali, we have no data on pneumopathies in this population, hence the interest of this study. The objective of this work was to determine the frequency of pneumopathies in patients with chronic renal failure, describe the clinical radio-types, identify the microorganisms involved, and assess the renal prognosis of pneumopathies. Materials and Methods: This was an 18-month prospective and descriptive study from January 1, 2018 to June 30, 2019 conducted in the nephrology and hemodialysis department of the University Hospital of Point G. Included were patients hospitalized during our study period with CKD associated with pneumopathy on a chest X-ray. Not included were all patients hospitalized outside the study period, all CKD cases without pneumonia, patients with incomplete records, and non-consenting patients. Results: We examined 1111 patients, 35 of whom presented an image on chest X-ray related to pneumopathy, a frequency of 3.15% of cases. Twenty-one men (60%) and 14 women (40%) with a sex ratio of 1.5. The mean age was 46.8 ± 13.9 years with extremes of 23 and 76 years. The types of pneumopathy on the chest X-ray were: alveolar pneumopathy: 23 cases (65.7%), pleuropneumopathy: 10 cases (28.6%) and cavitary pneumopathy: 2 cases (5.7%). Cytobacteriological sputum examination was positive in 65.7%; leukocytes (68.6% of cases). The germs found were: Klebsiella pneumoniae (25.7% of cases), Escherica coli (11.4%), Pseudomonas aeruginosa (5.7%), Staphylococcus aureus (5.7%), Citrobacter freundi (5.7%), Enterococus sp. (2.9%), Enterobacter cloacae (2.9%), Candida albicans (5.7%). The search for acid-alcohol-resistant bacilli (BAAR) in sputum was positive in 4 cases (11.4%). There was an association between the results of cytobacteriological examination of sputum and the results of BAAR testing of sputum (p = 0.046).
