BackgroundCongenital adrenal hyperplasia (CAH) is a chronic disorder causing adrenal insufficiency and hyperandrogenism affecting the quality of life (QOL). The objective of the study was to assess the health-related QOL (HRQOL) in Egyptian children and adolescents with CAH and to identify factors affecting it.MethodsThis cross-sectional study included 200 CAH patients (with 21-hydroxylase deficiency [21-OHD]) who were assessed according to their age, sex, clinical phenotype, timing of genitoplasty, hospital admissions within the last year, compliance to treatment, regularity of follow-up, presence of complications and hormonal control. HRQOL was assessed using the World Health Organization (WHO)QOL-BREF questionnaire with four domains analyzed independently including physical, psychological, social and environmental domains, with higher scores indicating better QOL.ResultsThe study included 140 females and 60 males with a mean age of 6.6 ± 4.5 years, and 88% were salt-wasting (SW). Older patients had significantly lower QOL scores (r = − 0.151, p = 0.033). The physical domain correlated significantly with the degree of virilization (r = − 0.491, p = 0.001) and frequency of hospitalization (r = − 0.495, p < 0.001). The psychological domain was affected by age (r = − 0.157, p = 0.026) and timing of genitoplasty (r = − 0.326, p = 0.001), while the social domain was affected by age (r = −0.277, p < 0.005) and pubertal stage (r = − 0.195, p = 0.006). Females had lower scores at the psychological domain (p < 0.001), whereas males had lower scores at the physical domain (p = 0.003). Salt-losing patients had lower scores at the physical domain (p = 0.001). Patients with good hormonal control had higher scores at the physical domain (p = 0.03). Genitoplasty affected both psychological and social domains (p = 0.003 and 0.01, respectively). Patients with hypertension and hirsutism had lower QOL scores (p < 0.05).ConclusionsHRQOL was relatively more affected in CAH patients with older age, poor hormonal control, high frequency of hospital admissions and those who developed complications.
We studied two of the three patients with a hereditary defect in the biosynthesis of aldosterone originally described by Visser and Cost in 1964. All three presented as newborns with salt-losing syndrome and failure to thrive. The original biochemical studies showed a defect in the 18-hydroxylation of corticosterone. According to the nomenclature proposed by Ulick, this defect would be termed corticosterone methyl oxidase deficiency type I. We measured plasma steroids in the untreated adult patients and performed molecular genetic studies. Aldosterone and 18-OH-corticosterone were decreased, whereas corticosterone and 11-deoxycorticosterone were elevated, thus confirming the diagnosis of corticosterone methyl oxidase deficiency type I. Cortisol and its precursors were in the normal range. Genetic defects in the gene CYP11B2 encoding aldosterone synthase (P450c11Aldo) have been described in a few cases. We identified a homozygous single base exchange (G to T) in codon 255 (GAG) causing a premature stop codon E255X (TAG). This mutation destroys a Aoc II restriction site. Digestion of a PCR fragment containing exon 4 of CYP11B2 (261 bp) with this restriction enzyme revealed in the two patients homozygous for the E255X mutation only a 261-bp fragment, whereas the heterozygous parents had three fragments (261 bp from the mutant allele and 194 and 67 bp from the wild-type allele). The mutant enzyme had lost the five terminal exons containing the heme binding site, and thus there was a loss of function enzyme. We conclude that the biochemical phenotype of these prismatic cases of congenital hypoaldosteronism can be explained by the patients genotype.
Maternal-infant bonding is an affective maternal-driven process that occurs primarily to her infant. Prophylactic interventions or treatment of disordered bonding include infant massage. Evidence suggests that oxytocin plays an important role in facilitation of mother–infant bonding. Main objective is to assess the effect of infant massage on salivary oxytocin level of mothers and their infant during postpartum period. And to assess the difference of oxytocin level in normal and disordered maternal-infant bonding. This study is a quasi-experimental study, carried out on 37 pairs of mothers and their infants from second to sixth month postpartum, attending Basateen Gharb primary health care center (PHC) in Albasateen district, Cairo, Egypt. Postpartum Bonding Questionnaire (PBQ) was used to differentiate between mothers with normal and disordered bonding. Pre and post massage salivary samples were taken from mothers and their infants. Tappan’s technique of infant massage was used. Results showed that 48.6% (N = 18) of mothers had disordered maternal infant bonding. Mothers and infants with normal bonding showed a positive relationship with their salivary oxytocin level post massage. On the other hand, mothers and infants with disordered bonding showed no change in their salivary oxytocin level post massage. Salivary oxytocin level in male infants has decreased post massage, while oxytocin level in female infants has increased post massage in mothers with normal bonding. We concluded that infant massage increases salivary oxytocin level in mothers and infants with normal bonding and it has no effect on salivary oxytocin level of mothers and infants with disordered bonding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
