The most common 21-hydroxylase deficiency is characterized by a cortisol deficiency and an excess of androgens, with or without aldosterone deficiency. In our countries, in the absence of neonatal screening, the diagnosis is most often late leading to life-threatening complications. The aim of this study was to describe the diagnostic features of CAH at the Albert Royer National Children’s Hospital (ARNCH) in Dakar.?Patients and method:?We conducted a retrospective, descriptive study carried out at the pediatric endocrinology department of ARNCH from 2015 to 2019. All children aged under 15 with a form of CAH were included. Socio-demographic data, family history, clinical and biochemical data at presentation were collected. Patients were noted as presenting with Disorder of Sexual Development (DSD) with dehydration, DSD without dehydration, dehydration without DSD, precocious puberty. The Prader’s scale was used to determine the degree of external virilization. These data were entered and analyzed with Epi Info version 7.2.?Results:?A total of 32 patients were included, representing 74.41% of the causes of disorder of sexual development (DSD) and 84.21% of the causes of adrenal insufficiency. These were 27 girls (84.37%) and 5 boys (15.63%). The mean age was 19 ± 34.6 months. DSD was the main finding (87.5%). It was associated with dehydration in 22 cases (68.75%). 21-hydroxylase deficiency represented 93.75% of the cases with salt wasting in 73.33% of the cases.?Conclusion:?The diagnosis of CAH was delayed leading to life-threatening adrenal crises. In the absence of neonatal screening for CAH in Senegal, there is a need to train healthcare workers to recognize neonates with DSD early and refer them timeously for specialist care.展开更多

Methods By using PCR-ASO hybridization analysiswith amplified segments involving exon 3-4 and exon 6-8 of the gene to investigate for the type ofmutations. Results The results showed among 5 point mutations detected positive findings being in 28/66 (42%)of CAH chromosomes, or 17/33 (52%) of the CAH cases examined. The only 1 non - classic form CAH case wasfound as homonsous for val - 281→len mutation. Three classic cases were heterozygous for compound mutations asnitron 2 A, C→G associated with lie-172→Asn or lie - 172→Asn with Gin-318→stop. The other point mutationsall revealed as homozygous alleies with the most freguent matations as nitron 2A, C→G. No PCR product wereprovided by 3 cases who had been verilied by Southern blotting with CYP21 B gene deletion (not shown). NO pointmutations were illustrated in normal controls. Conclusion This report presentS data in 17/33 (52K) of Chinesechildren with CAH in CYP 21 B gene had point mutations documenting the type and location of mutation indiagnosis of CAH.展开更多

This will play a significant role inguiding diagnosis and treatment.展开更多

It is a rare monogenic recessive disorder. In African setting in absence of neonatal screening, the diagnosis is still late, based on a clinical approach. During this clinical enquiry, information from past history or pedigree of the patient is of a huge importance and may revealed surprises. Patients and Methods: In this observational study, we retrospectively included all patients with a diagnosis of CAH. The diagnosis of CAH was retained based on a high 17 hydroxyprogesterone level in addition to clinical and morphological findings. From patients’ files, we extracted data on family history of disease, pedigree, clinical findings and genetics when available of 39 patients from two endocrinopeadiatric centers. Results: In 13 (30%) families, we found 20 reported deaths of infant less than 12 months. In these 13 families, half of the patients followed had 21 hydroxylase deficiencies and had 11 hydroxylase deficiencies. Unsurprisingly, we suspected adrenal insufficiency in these patients at verbal autopsy even in families with a patient with 11 hydroxylase deficiency. Other non DSD malformations or genetic disorders with apparently no link with CAH were reported in 3 families. The father of a patient reported to have hypospadias. Conclusion: Each diagnosis of CAH made in our context is visible part of an iceberg. Behind a diagnosis of CAH made in our setting, is a long course of care, a dramatic past history revealing access to appropriate care disparity. Neonatal screening should thus be considered as an emergency.展开更多

Methods: 11 cases of female pseudohermaphroditism (8-27 years old) were analyzed retrospectively. Results: In 9 of the 11 patients with female pseudohermaphroditism who did no receive hormone replacement therapy, both internal and external branches of bilateral adrenal glands were found to be thickened, prolonged and twisted, and in 2 of the 9 patients they were found to be macronodularly hyperplasic. In one of the remaining two patients who had received long-term hormone replacement therapy, the adrenal glands were not thickened or twisted, though prolonged; and in the other patient imaging presentation of the adrenal glands was the same as that of those who did not receive hormone replacement therapy, but with co-existence of adrenal myelolipoma. Among the 11 patients agenesis of the uterus and the vagina was found in 4 cases. Conclusion: Female pseudohermaphroditism is a hereditary disease, where hyperplasia of the adrenal glands and agenesis of the uterus and the vagina were secondary. Early detection of these abnormalities by imageology would prove to be helpful in early detection and treatment of the condition.展开更多

文摘Dear editor:Congenital adrenocortical hyperplasia(CAH)is an autosomal reces-sive disease resulting from a deficiency in the cortisol synthase gene.This deficiency leads to an imbalance in adrenocortical hormones and excess androgen.21 Hydroxylase deficiency(21-OHD)is the most common form of CAH,accounting for 90%~95%of cases.1 This condition is pri-marily caused by a mutation in the CYP21A2 gene,located on chromo-some 6p21.3.2 Depending on the severity of aldosterone deficiency,CAH can be divided into classical(salt-wasting and simple-virilizing forms)and non-classical(NCCAH)types.Excess androgen,the most common factor in classical CAH and NCCAH,can negatively impact fertility in CAH patients.The spontaneous rate of pregnancy without treatment is typically very low in CAH patients.
文摘Objective: To discuss imaging features of the adrenal glands in female pseudo-hermaphroditism. Methods: 11 cases of female pseudohermaphroditism (8-27 years old) were analyzed retrospectively. Results: In 9 of the 11 patients with female pseudohermaphroditism who did no receive hormone replacement therapy, both internal and external branches of bilateral adrenal glands were found to be thickened, prolonged and twisted, and in 2 of the 9 patients they were found to be macronodularly hyperplasic. In one of the remaining two patients who had received long-term hormone replacement therapy, the adrenal glands were not thickened or twisted, though prolonged; and in the other patient imaging presentation of the adrenal glands was the same as that of those who did not receive hormone replacement therapy, but with co-existence of adrenal myelolipoma. Among the 11 patients agenesis of the uterus and the vagina was found in 4 cases. Conclusion: Female pseudohermaphroditism is a hereditary disease, where hyperplasia of the adrenal glands and agenesis of the uterus and the vagina were secondary. Early detection of these abnormalities by imageology would prove to be helpful in early detection and treatment of the condition.
