Renal transplant recipient seizure practical management.

Seizures are not uncommon in renal transplant patients. The common aetiologies are metabolic disturbance associated with renal failure, immunosuppression and associated complications and infections. Their management can be challenging because of altered pharmacokinetics of antiepileptic drugs (AEDs) and their removal by dialysis. A practical approach to the management of seizure in renal transplant patients is discussed. This review highlights the guidelines for use of various AEDs in renal transplants.

Mycobacterium avium complex infection in non-cystic fibrosis bronchiectasis.

BACKGROUND AND OBJECTIVE: Reliable markers of disease progression or stability to assist in management decisions are lacking in patients with non-cystic fibrosis bronchiectasis and Mycobacterium avium complex (MAC) infection. METHODS: Data from 52 adults with non-cystic fibrosis bronchiectasis and coexisting MAC infection managed at our institution over a 5-year period were retrospectively analysed. High-resolution computed tomography (HRCT) scans were scored using a scoring system that focused on findings associated with MAC infection. RESULTS: Chronic pulmonary aspergillosis was independently associated with mortality (hazard ratio (HR) = 8.916, 95% confidence interval (CI) = 1.324-60.027), as were nodules with cavitation (HR = 5.911, 95% CI = 1.095-25.911) and emphysema (HR = 1.027, 95% CI = 1.002-1.053) on HRCT. Anti-MAC chemotherapy was more likely to lead to MAC culture conversion (67% vs. 27%, P = 0.005) but did not improve survival as compared with patients managed with observation. Longitudinally, patients who had improvements in HRCT scores were younger (60.2 ± 9.19 years vs. 69.83 ± 12.43 years, P = 0.043), while the presence of cavitation within nodules predicted a deterioration in HRCT scores (0.5 (0-3) vs. 0 (0-1), P = 0.033). No significant longitudinal differences were found in lung function in the cohort as a whole or within different groups. CONCLUSIONS: Chronic pulmonary aspergillosis in patients with bronchiectasis and coexisting MAC infection is a strong predictor of mortality. Cavitation within nodules and emphysema on HRCT at presentation were independently associated with mortality.

Lung clearance index and high-resolution computed tomography scores in primary ciliary dyskinesia.

RATIONALE: Lung clearance index (LCI) is a more sensitive measure of lung function than spirometry in cystic fibrosis (CF) and correlates well with abnormalities in high-resolution computed tomography (HRCT) scanning. We hypothesized LCI would be equally sensitive to lung disease in primary ciliary dyskinesia (PCD). OBJECTIVES: To test the relationships between LCI, spirometry, and HRCT in PCD and to compare them to the established relationships in CF. METHODS: Cross-sectional study of 127 patients with CF and 33 patients with PCD, all of whom had spirometry and LCI, of which a subset of 21 of each had HRCT performed. HRCT was scored for individual features and these features compared with physiological parameters. MEASUREMENTS AND MAIN RESULTS: Unlike in CF, and contrary to our hypothesis, there was no correlation between spirometry and LCI in PCD and no correlation between HRCT features and LCI or spirometry in PCD. CONCLUSIONS: We show for the first time that HRCT, spirometry, and LCI have different relationships in different airway diseases and that LCI does not appear to be a sensitive test of airway disease in advanced PCD. We hypothesize that this results from dissimilarities between the components of large and small airway disease in CF and PCD. These differences may in part lead to the different prognosis in these two neutrophilic airway diseases.
