To evaluate the efficacy of renal transplantation in small pediatric patients, we have reviewed 41 allografts performed in 39 children (28 M/11 F) less than 6 years of age between 1987 and 1998 in the North Italy Transplant Program. Of these patients, 39 had a cadaver donor and 2 a living-related donor, with ages ranging from 20 days to 35 years. The mean follow-up was 56 months. Graft survival was 74.5% and 70.5% at 1 and 5 years, respectively. The causes of graft lost were acute rejection (4), graft vascular thrombosis (4), and hemolytic uremic syndrome recurrence (1). Only 1 patient has died due to chickenpox. Double and triple immunosuppressive therapies were used in 63% and 37% of patients, respectively, on the basis of different center protocols, without differences in graft survival. Steroids were successfully administered on alternate days in 37% of patients, 6-12 months after transplantation. Thrombosis was reported in 2 of 6 kidneys from donors less than 1 year of age and in 2 of 35 donors older than 1 year (P < 0.05). Thirty rejections occurred in 23 patients: 7 episodes were steroid resistant and were treated with ATG/OKT3. Thirty-four infections were reported in 16 of 41 patients; of these 17 were viral, 14 bacterial, and 3 due to Mycoplasma. Four surgical complications were reported: 1 graft artery stenosis, 1 ureteral stenosis, 1 urinary leak, and 1 lymphocele. Mean height standard deviation score improved from -2.0 +/- 1.3 pre transplantation to -1.8 +/- 1.4, -1.5 +/- 1.3, and -1.5 +/- 1.5 at 1, 2, and 5 years post transplantation. Linear growth was significantly better in infants treated with alternate-day steroids. Hypertension was a frequent complication, since 19 of the 30 patients with a 5-year follow-up were still being treated with antihypertensive drugs. In conclusion, graft survival in patients less than 6 years old is satisfactory and similar to that obtained in children aged from 6 to 18 years (70.5% vs. 78.9% at 5 years, P = NS). Consequently, since there are many difficulties in managing infants on maintenance dialysis, an early transplant should be considered. Donors older than 24 months carry a low risk of vascular thrombosis and may be successfully grafted in infants.

A 78-year-old man with diabetes mellitus, hyperthyroidism and congestive heart failure was admitted to our hospital because of dyspnea on effort. He had been taking 200 mg/day amiodarone for 2 years, in order to treat a intermitted ventricular tachycardia. His chest X rays showed the appearance of diffuse consolidation in the right lung field. At first severe pulmonary infection was suspected, and he was treated with antibiotics. In spite of the treatment, the chest X-ray findings did not improved. We thought of the possibility of interstitial lung disease, and performed bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB) from the right middle lobe. TBLB revealed the organizing pneumonia (OP). At the same time we observed that he had temporary sinus arrest and entered a stated of shock requiring intubation, temporary pacing and intra-aortic balloon pumping (IABP) . The coronary angiography (CAG) revealed no abnormalities and cardiac function was normal. Within two days his sinus rhythm recovered spontaneously. After cessation of amiodarone and administering steroid therapy, pulmonary shadows resolved quickly. Since there were no laboratory signs of connective tissue or infectious disease such as a normal autoimmune serology, antibody titers against Mycoplasma pneumoniae, Clamydia species, and BAL, TBLB cultures, etc, we considered that unilateral organizing pneumonia and temporary sinus arrest could be induced by amiodarone. The amiodarone pulmonary toxicity (APT) commonly courses pleural effusion and while it may be strictly unilateral, there are often diminutive contralateral foci visible on HR-CT. Steroids should be given for months and tapered prudently, otherwise APT may recur owing to the persistence of amiodarone in lung.

The aim of the present study was to outline any predisposing factors and clinical and radiological features of post-infectious bronchiolitis obliterans (PIBO) in pediatric patients, and to determine the effect of long-term azithromycin treatment on these factors. In total, 16 cases of children with PIBO were retrospectively reviewed. Adenovirus and Mycoplasma pneumoniae were the most common etiological agents (12/16) in the children with PIBO. The patients presented with persistent dyspnea, a chronic cough, sputum production and wheezing following the initial lung infection. Chest X-rays indicated pulmonary overinflation and patchy ground-glass opacity. In addition, high-resolution computed tomography (HRCT) scans revealed patchy ground-glass opacity, bronchiectasis, bronchial wall thickening and mosaic perfusion in all 16 cases. A unilateral hyperlucent lung was observed in two cases. All the patients underwent treatment with low-dose azithromycin and prednisone. Follow-up examinations of the 16 cases, varying in duration between 7 and 31 months, showed that the disease condition had improved in 10 cases. However, no significant improvements were identified from the HRCT scans or were observed in the patient condition in the additional six cases. The diagnosis of BO is primarily based on a typical clinical presentation and HRCT observations. Therefore, a typical clinical history and patchy ground-glass opacity features on HRCT scans are screening indices that predict BO development. Steroids are the cornerstone of BO treatment; however, long-term azithromycin treatment can improve the condition of the patients. In summary, PIBO is a disease with a high morbidity rate and should be treated by a multidisciplinary team. Patients should receive follow-up examination for an extended period. Patchy ground-glass opacity features on HRCT scans indicate that clinical suspicion of BO is necessary in children with persistent and severe wheezing.
