A brief, systematic and structured cognitive behavioural intervention (CBI) decreases anxiety and depression symptoms and improves quality of life in patients with end-stage renal disease (ESRD) who are being treated with haemodialysis. These benefits are not achieved when anxiety and depression symptoms are identified but not treated psychologically. This CBI consisted of cognitive restructuring of the distorted thoughts (perfectionism, catastrophic thinking, negative self-labelling, and dichotomous thinking) that are correlated with depression and anxiety symptoms and that can be assessed by a validated questionnaire designed for patients with ESRD. The handbooks that were developed for this study are structured and systematic. They could be valuable in supporting the efforts and participation of non-specialized health professionals in CBI such as nurses, physicians, social workers, and psychologists, raising the possibility of further application in a variety of clinical populations. Both the therapy and the client workbooks are available in Spanish upon request.

Kidney transplant (KT) resolves many of the cardiac abnormalities associated with chronic kidney failure (CKF). This study analyzed cardiac alterations of kidney failure and their modification with transplant. Thirteen patients in CKF underwent conventional echocardiograms, dobutamine stress echocardiograms, and injection of contrast to examine perfusion before KT and 3 months after transplant. Nine patients had evidence of left ventricular hypertrophy and six had evidence of diastolic dysfunction. Wall thickness, left ventricular mass, and mass index diminished after KT; only two patients continued to manifest hypertrophy. Left ventricular systolic diameters and volumes diminished at 3 months, and diastolic diameters after 4 months. Left ventricular fractional shortening and ejection fraction increased 3 months after transplant. At the end of the study, only two patients continued to show diastolic dysfunction. Dobutamine echocardiograms showed no segmental wall-movement abnormalities. Myocardial perfusion was normal before and after transplant. The results suggest that KT diminishes hypertrophy and improves left ventricular systolic and diastolic function. Echocardiography provides valuable information for detection and follow-up of cardiac abnormalities in patients with kidney disease. Evaluation of segmental wall movement and myocardial perfusion aid in demonstrating that our studied patients with CKF had no indirect signs of coronary artery disease.

Hypertension and renal mass reduction induce glomerular hypertension (GH), hyperfiltration (HF) and renal injury. GH may contribute to allograft loss in post-transplant hypertensive patients (PT x HT). HF and GH may be evaluated by renal response to acute protein intake (API). Since ACE inhibition may prevent GH, the effects of fosinopril (Fos) were evaluated in 10 PT X HT on azathioprine and prednisone. Patients received 5 to 40 mg/day of Fos during 12 months. Baseline MAP (111.1 +/- 2.9 mm Hg) was significantly reduced by 10 to 12 mm Hg, rising to 114.7 +/- 2.7 mm Hg after Fos was administered. GFR (63.7 +/- 5.9 ml/min) decreased after 4 (48.1 +/- 4.6, P less than 0.05) and 12 months (50.7 +/- 4.6, P less than 0.05), rising to 59.4 +/- 5.6 after Fos was given. There was no GFR response to API before and after one month of Fos, however, a clear response became apparent at 4 (+ 27% P less than 0.05), and 12 months (+ 18%, P less than 0.05), disappearing after Fos discontinuation. Proteinuria (918.8 +/- 710.6 mg/d) decreased after 4 (72.3 +/- 21.6 mg/d, P less than 0.05) and 12 months, rising to 297.8 +/- 172.3 mg/day after therapy. GFR response to API in 22 controls and 17 uninephrectomized donors was 13 and 11%, respectively. Lack of response to API in PT x HT suggests HF and GH. Reduction of GFR, restoration of response to API and reduction of proteinuria, indicate that ACE inhibition with fosinopril ameliorates HF and GH. This effect may be beneficial in preventing hemodynamic-mediated allograft injury.
