Stature-weight growth delays: Clinical and etiological aspects.

BACKGROUND

Stature-weight growth delay (SWGD) is a frequent motivation of consultation. It could be a consequence of a known chronic affection, congenital or acquired affection. The purpose of this study is to describe epidemiological, clinical, paraclinical, and etiological aspects of SWGD.

PATIENTS AND METHODS

This retrospective study included 103 patients presenting a growth delay with an average age of 14.44 years and ranging between 5 and 21 years. Male predominance was noticed in 68.93% of cases. Patients showed a stature lower to -2 standard deviation (SD) for corresponding age compared to Sempe and Pedron reference. Patients were hospitalized in Endocrinology and Metabolic Diseases Department of the University Hospital of Fez, Fez, Morocco.

RESULTS

Patient's history included a perinatal suffering in 6.7% of cases, a chronic pathology follow-up in 17.6% of cases, and psychomotor development disorder in 10.6% of cases. The average weight was -2.37 SD with extremes varying from -4 to -0.5 SD. The stature values varied between -4.5 and -2 SD for the given age, with an average of -3.12 SD. A severe stature delay (< -3 SD) was recorded in 39.6% of cases and the targeted average size was -2.44 SD with extremes varying from -4 to -1.5 SD. Growth delay etiologies were dominated by a deficit in growth hormones (GHs) in 60% of cases.

DISCUSSION AND CONCLUSION

Dynamic tests objectified a total deficit and partial deficits in GH in 41.7 and 30% of patients, respectively. The hypothalamo-pituitary magnetic resonance imaging was pathological in 23.3% of patients and showed a syndrome of interruption of pituitary stem in seven patients, pituitary hail gland in three patients, a craniopharyngioma in two patients, prolactin microadenoma in one patient, and nonfunctional pituitary microadenoma in one patient. GH treatment was established in 16 children that were presenting a deficit in GH, and two girls presenting Turner syndrome, whereas etiological treatment was suggested in all remaining cases.
