Introduction. Infantile nephropathic cystinosis (INC) is a metabolic disorder
due to impaired carrier-mediated transport of cystine out of cellular
lysosomes. Objective. To examine the prevalence and clinical characteristics
of INC in paediatric patients with end- stage renal disease (ESRD) in Serbia
and give a recent statement of the disease. Methods. ESRD database of the
Centre for Paediatric Renal Replacement Therapy (RRT) in Serbia was used to
identify all patients with INC who started RRT before age of 19 years during
the period January 1980 - December 2008; their records concerning clinical
characteristics, therapy and outcome were evaluated. Results. Only three of
298 paediatric patients with ESRD had INC. The first signs of the illness
were recognised during infancy. Fancony syndrome was diagnosed in the second
year, but the diagnosis of cystinosis was delayed at mean 6 years. ESRD
occurred in the first decade of life. All patients under- went cadaver kidney
transplantation. At the end of the study period all patients were alive. A
31-year-old female patient was on maintenance chemodialysis due to graft
failure after functioning for 11 years. She was growth retarded, single,
unemployed, with severe signs of renal dystrophy. Two male patients (14.3 and
14.7 years old) had normal graft function, normal education, and good quality
of life, although they were also severe growth retarded. Conclusion. The
prevalence of infantile nephropathic cystinosis is low in Serbia. The
diagnosis of cystinosis was delayed in all patients, although they exhibited
the typical course of the disease.
