Despite biochemical screening confirming ACTH-independent CS, imaging modalities including computed tomography and magnetic resonance imaging showed normal adrenal gland morphology, complicating the localization of cortisol hypersecretion. Subsequent nuclear imaging methods were not indicative of ectopic cortisol production until adrenal vein sampling (AVS) conclusively identified the adrenal glands as the only possible source of cortisol hypersecretion. Eventually, bilateral adrenalectomy led to a significant improvement in symptoms. Pathological examination confirmed the diagnosis of PPNAD, and genetic testing revealed a mutation in the PRKAR1A gene associated with the Carney complex. This case highlights the importance of considering rare etiologies in hypercortisolism diagnosis and describes their challenging diagnostic workup and the utility of AVS in localizing cortisol hypersecretion in PPNAD patients.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"2 10","pages":"luae174"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11443333/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142360735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a case of a 16-year-old Asian male patient, with short stature and progressive bone deformity, whose biochemical parameters revealed low levels of 1,25(OH)2 vitamin D, low serum calcium levels, along with high phosphorus and raised levels of intact parathyroid hormone. These biochemical parameters suggested the diagnosis of pseudohypoparathyroidism. The patient also had concurrent extrapulmonary tuberculosis during the time of presentation to our endocrine unit. However, on molecular testing, it was revealed that the patient was harboring pathogenic variants of the CYP27B1 gene, in a compound heterozygous manner, with a novel missense mutation in exon 6 of the CYP27B1 gene, c.1136G > C (p.Arg379Thr), suggesting the diagnosis of vitamin D-dependent rickets type 1A. The cause of high phosphorus at the time of presentation, which led to a diagnostic dilemma of pseudohypoparathyroidism, was later explained by presence of active extra pulmonary tuberculosis.

Approximately 30% of NEN exhibit functional activity with clinical syndromes through hormone-mediated effects. Synchronous and metachronous functioning syndromes, resulting from the simultaneous release of distinct hormones, are exceptionally rare. Of note, hormonal excess syndromes can have a greater effect on patients' morbidity and mortality than the tumor mass itself. We present the case of a 49-year-old male patient affected by an oligo-metastatic ileal NEN, concurrently demonstrating vasointestinal peptide (VIP) and serotonin excretion, complicated by pulmonary tuberculosis. After the first cycle of Lutetium-177-DOTATATE peptide-radio-receptor therapy, the patient developed a severe watery diarrhea, hypokalemia, and achlorhydria (WDHA) syndrome, despite receiving high-dose somatostatin analogues, everolimus, and telotristat ethyl, without any surgical options. The WDHA syndrome necessitated intensive-care-unit (ICU) admission with continual intravenous administration of electrolytes and fluids. With limited alternatives, an off-label intervention using the enkephalinase inhibitor racecadotril was initiated. After 5 days of treatment, the WDHA syndrome exhibited sufficient control, facilitating the patient's discharge from the ICU. This case report underscores racecadotril as an individualized, off-label treatment strategy for patients with severe VIPoma and serotonin-driven WDHA syndrome, where conventional therapeutic avenues have been exhausted.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"2 10","pages":"luae177"},"PeriodicalIF":0.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11439523/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142333883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patient was started on cabergoline with rapid normalization of PRL levels and resolution of symptoms, in keeping with previous reports. Cabergoline has a stronger affinity for the D2R receptor and longer half-life than L-Dopa, leading to lactotroph apoptosis, tumor shrinkage, and rapid and maintained normalization of PRL levels, with a better side-effect profile. Patients with DHPR deficiency need to be actively monitored for symptomatic hyperprolactinemia, as L-Dopa monotherapy is insufficient to suppress PRL secretion, leading to lactotroph hypertrophy and proliferation over time and development of prolactinomas in later life.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"2 10","pages":"luae172"},"PeriodicalIF":0.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11427838/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142333885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She presented with diaper rashes, oral thrush, and tetany during infancy due to candidiasis and hypoparathyroidism. During childhood, she developed hypothyroidism, primary adrenal insufficiency, and ovarian insufficiency. At age 14, she received a sibling-matched allogenic bone marrow transplant due to multiple antibiotic-refractory fungal infections. At age 35, her serum triglycerides were 914 mg/dL (10.32 mmol/L) and she had loss of subcutaneous fat from the upper and lower extremities and hips.
