Epidemiologic survey of patients treated with growth hormone in France in the period 1959-1990: preliminary results.

Because the delivery of growth hormone (GH) was centralized from 1977 in France, it has been possible to conduct, during the second half of 1990, a nationwide survey of the health status of patients treated with GH from the year 1959. A questionnaire regarding the 5,546 patients recorded for the period 1959-1990 was sent to the prescribers or the patients. 5,418 more or less completely documented reports were obtained. The mean age of the patients at the onset of GH treatment was 11.0 +/- 4.1 years. 1,937 of them had at this time some important disease associated with GH deficiency. The mean duration of treatment was 3.99 +/- 3.05 years. 3,446 patients were still under follow-up. Very recent information (1990-1991) was given for 82.7% of patients, less recent data (1985-1989) for 13.4%. For 3.9%, no data beyond 1985 were obtained. 77 patients had died, 38 from neoplastic disease (mainly recurrence of a primary malignancy), 10 from accident, 3 by suicide, 7 with neurological disease [only 1 case of Creutzfeldt-Jakob disease (CJD) was reported at the time of the survey], the others from various causes. No abnormal frequency of posttreatment leukemia, lymphoma, malignancies, hip diseases, glucose intolerance or other disease focusing attention, was found in the survey. From the time when this survey was completed (December 1990) to that of this report (May 1992), other cases of CJD have been reported in France: 3 ascertained, 7 clinically resembling but not yet certain. These 10 patients were treated for complete GH deficiency, 6 of congenital or neonatal cause and 4 after neurosurgery.(ABSTRACT TRUNCATED AT 250 WORDS)
