Is it possible to achieve an acceptable disease control by dietary therapy alone in Berardinelli Seip type 1? Experience from a case report. Front Endocrinol (Lausanne) 2023; 14:1190363.

Abstract
Background and objective Severe metabolic complications generally manifest at an early age in Berardinelli - Seip congenital lipodystrophy (BSCL) and their management is especially challenging. Nutritional intervention with low lipid diets is considered by experts to be fundamental in treating the disease when associated with medical therapy, however little is known about the beneficial effects of dietary interventions alone. Aim To underline the importance of a well-structured low-fat diet in BSCL patients. Methods and results A BSCL male patient strictly followed a hypocaloric hypolipemic diet (60% carbohydrates, 22% fats and 18% proteins) since clinical diagnosis at the age of one year. Interestingly, pharmacological interventions were not required at any point during the follow-up. Aged 16 years the patient was referred to our center. Biochemistry, hormonal evaluation, 75 mg oral glucose tolerance test, cardiac evaluation and abdominal ultrasound were performed, revealing no abnormalities. Genetic analysis and leptin dosage were carried out, confirming the diagnosis of BSCL type 1 (homozygosity for c.493-1G>C pathogenic variant in AGPAT2 gene) and showing undetectable circulating levels of leptin (< 0.2 mcg/L). Diet therapy alone was therefore maintained, scheduling follow-up visits every six months, with acceptable disease control ever since. Conclusions This report proves how a low-fat diet is of great help in the management of BSCL and its complications. In addition, a specific hypolipemic diet could be used alone as an effective treatment in selected cases with high compliance and, probably, a milder phenotype.

Isolated transient neonatal clitoromegaly with hyperandrogenism of unknown etiology. J Pediatr Adolesc Gynecol 2009; 22:e142-5. [PMID: 19592278 DOI: 10.1016/j.jpag.2009.01.066] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2008] [Revised: 01/11/2009] [Accepted: 01/19/2009] [Indexed: 11/22/2022]
Abstract
BACKGROUND Neonatal clitoromegaly is usually attributed to androgen stimulation secondary to congenital adrenal hyperplasia or in utero androgen exposure. We present a unique case of transient, isolated neonatal clitoromegaly, associated with increased androgen levels of unidentifiable cause, which spontaneously resolved when the androgen levels normalized. This is the first report where, despite an exhaustive workup, the cause of hyperandrogenism remains unknown. CASE A female infant was delivered at 25 + 5 weeks gestational age. Clitoromegaly was first documented at 3 months of age (18 mm long, |13 mm wide). There was no other evidence of virilization. There was no neonatal history of transfusions or androgen-medication exposure. Initial bloodwork documented extremely high levels of free testosterone (117 pmol/L) and dehydroepiandrosterone sulfate (DHEAS). Further tests ruled out the following diagnoses: 21-hydroxylase deficiency, 11-betahydroxylase deficiency, testicular feminization, presence of ovotesticular tissue, and androgen-secreting tumors. Maternal history ruled out in utero androgen exposure, maternal drug use, hyperandrogenism, or virilization during pregnancy, and antenatal imaging had not detected a maternal ovarian mass or adrenal tumor. The infant's androgen levels spontaneously declined, and by 4 months of age had normalized without therapy (free testosterone 8 pmol/L). At 5 months of age, the clitoral measurements normalized (10mm long, 5mm wide). CONCLUSION In this case of a premature female infant, hyperandrogenism and clitoromegaly resolved spontaneously. Only 1 other case of hyperandrogenism and clitoromegaly that resolved spontaneously in a preterm infant has been reported. In that case, the clitoromegaly and high testosterone levels were attributed to repeated blood transfusions from an adult male. The etiology of the hyperandrogenism and resultant clitoromegaly in our case is not known.

Abstract
BACKGROUND: Clitoromegaly is a frequent congenital malformation, but acquired clitoral enlargement is relatively rare. METHODS: Two acquired clitoromegaly cases treated in Ataturk Training Hospital, Izmir, Turkey are presented. RESULTS: History from both patients revealed clitoromegaly over the last three years. Neither gynecological nor systemic abnormalities were detected in either patient. Karyotype analyses and hormonal tests were normal. Abdominal and gynaecological ultrasound did not show any cystic lesion or other abnormal finding. Computerized tomography scan of the adrenal glands was normal. Clitoroplasty with preservation of neurovascular pedicles was performed for the treatment of clitoromegaly. CONCLUSION: The patients were diagnosed as "idiopathic isolated" clitoromegaly. To the best of our knowledge, there has been no detailed report about idiopathic clitoromegaly in the literature.

Mutations in Gng3lg and AGPAT2 in Berardinelli-Seip congenital lipodystrophy and Brunzell syndrome: phenotype variability suggests important modifier effects. J Clin Endocrinol Metab 2004; 89:2916-22.

Abstract
Congenital generalized lipodystrophy (CGL) is a rare autosomal recessive disorder caused by mutations in AGPAT2 and Gng3lg. We screened for mutations in AGPAT2 and Gng3lg in 26 families with CGL and one family with Brunzell syndrome. We found mutations in either AGPAT2 or Gng3lg in all but four probands, including three novel mutations in AGPAT2, A712T (Lys215X), IVS3-1G-->C, and C636A (Phe189X). In three siblings with Brunzell syndrome, we identified a splice site mutation (IVS4-2A-->G) in AGPAT2, showing that AGPAT2 mutations can also cause Brunzell syndrome. Eighteen CGL patients from 15 families from the same region of northeastern Brazil were homozygous for a frameshift mutation (669insA of AF05149) in Gng3lg. Despite having the same mutation, the subjects had widely divergent clinical manifestations. In our subjects, there did not appear to be any distinguishing clinical characteristics between CGL subjects with AGPAT2 or Gng3lg mutations with the exception of mental retardation in carriers of Gng3lg. In summary, mutations in AGPAT2 and Gng3lg are approximately equally represented in CGL; despite harboring the same Gng3lg mutation, subjects may have widely divergent clinical manifestations, suggesting modifying influences of other genes and/or environment; and Brunzell syndrome may be caused by a mutation in AGPAT2.
