ABSTRACT

Tuberous sclerosis complex (TSC) is a genetic disease that leads to formation of tumors i.e. in brain kidneys, heart, lungs, and skin. AIM: The aim of the study was to summarize center's experience in the first year of program of nephrologic follow-up in patients with TSC. MATERIALS AND METHODS: During 12 months 30 children with TSC (14 boys and 16 girls aged from 3 months to 17 years 11 months, mean 7.57±5.02 years) were hospitalized. Following parameters were evaluated: genetic and biochemical tests, blood pressure in ambulatory blood pressure monitoring (ABPM), kidney lesions in ultrasonography (30 patients) and in magnetic resonance (14 patients). RESULTS: Genetic tests were performed in 6 children - in 5 TSC2 mutation was found, in one boy with TSC and numerous renal cysts only PKD1 mutation was revealed. Mean GFR was 130.81±23.23 mL/ min/1.73 m2. Four children (13.3%) had arterial hypertension. Renal lesions were found in 28 (93.3%) children: 18 patients had angiomyolipomas (AML) (mean diameter 15.4±12.5, max 38 mm), 23 patients had renal cysts (mean diameter 7.6±7.0, max 30 mm); 13 patients had AMLs and cysts. A dysplastic lesion (39x26x15 mm) in right kidney was found in one girl. Children with AML were older than remaining patients (10.08±4.55 vs. 4.25±3.50 [years], p<0.001). Children with cysts were characterized by higher systolic (p=0.017), diastolic (p=0.027) and mean (p=0.014) arterial pressure, and mean arterial pressure Z-score (p=0.025) in ABPM. Maximal kidney cyst diameter correlated positively with systolic, diastolic, mean arterial pressure, mean arterial pressure Z-score, and diastolic blood pressure load in ABPM (r = 0.61-0.75, p = 0.033-0.005). Two children with numerous AML with diameter >30 mm were treated with sirolimus. CONCLUSIONS: Because of common focal lesions in kidneys children with TSC should be kept under regular nephrologic follow-up. Presence of large renal cysts may predispose children with TSC to arterial hypertension.

ABSTRACT

BACKGROUND/AIM: Chronic myeloid leukaemia (CML) rarely affects the paediatric population and has an incidence of 0.06-0.12/100,000 children per year. The dire clinical course of paediatric CML is further exacerbated by the adverse effects of long-term imatinib therapy. PATIENTS AND METHODS: Our cohort comprised 14 CML patients who were treated with imatinib between July 2010 and September 2018. The European Leukaemia Net (ELN) standard milestones of response criteria were used to evaluate its therapeutic effectiveness. RESULTS: Complete haematological remission and partial cytogenetic response were achieved in all patients. Complete cytogenetic response was achieved in seven patients. Major molecular response was achieved in six patients. Two patients underwent haematopoietic stem cell transplantation due to unsatisfactory response to imatinib. CONCLUSION: Imatinib is effective in treating paediatric CML and limits the progression to advanced stages, however, the quality of life still needs to be optimised.
