     View Summary

    AIM: The present cohort study explored whether specific gut microbiota (GM) profile would predict the development of impaired glucose tolerance (IGT) in individuals with normal glucose tolerance (NGT). METHODS: A total of 114 study subjects with NGT in Kumejima island, Japan participated in the present study and underwent 75 g oral glucose tolerance tests at baseline and one year later. We compared the profile of GM at baseline between individuals who consistently maintained NGT (NRN, n = 108) and those who transitioned from NGT to IGT (NTI, n = 6). RESULTS: Within-individual bacterial richness and evenness as well as inter-individual bacterial composition showed no significant differences between NRN and NTI. Of note, however, partial least squares discriminant analyses revealed distinct compositions of GM between groups, with no overlap in their 95 % confidence interval ellipses. Multi-factor analyses at the genus level demonstrated that the proportions of CF231, Corynebacterium, Succinivibrio, and Geobacillus were significantly elevated in NTI compared to NRN (p < 0.005, FDR < 0.1, respectively) after adjusting for age, sex, HbA1c level, and BMI. CONCLUSIONS: Our data suggest that increased proportion of specific GM is linked to the future deterioration of glucose tolerance, thereby serving as a promising predictive marker for type 2 diabetes mellitus.

  • Impact of the transition from radioimmunoassay (RIA) to chemiluminescent enzyme immunoassay (CLEIA) for the measurement of plasma aldosterone concentration (PAC) on the diagnosis of primary aldosteronism (PA) via retrospective analyses in Okinawa, Japan.

     View Summary

    In Japan, the traditional method for measuring plasma aldosterone concentration (PAC) was radioimmunoassay (RIA), which had several challenges, including poor traceability of certified reference materials and reduced detection sensitivity at low concentrations. To overcome these issues, a chemiluminescent enzyme immunoassay (CLEIA) for PAC measurement was introduced in April 2021 and the Japan Endocrine Society published new guidelines for primary aldosteronism (PA). This study aimed to evaluate the impact of the transition from RIA to CLEIA for PAC measurement on PA diagnosis. Data from 190 patients admitted to the Second Department of Internal Medicine, University of the Ryukyus Hospital, between April 2012 and March 2021 were analyzed. Patients who were diagnosed with PA underwent adrenal venous sampling. The PAC measured by RIA (PAC(RIA)) was converted to the estimated PAC measured by CLEIA (ePAC(CLEIA)) using a conversion formula. The present study evaluated the discordance rates in diagnoses based on screening (SC), captopril challenge test (CCT), saline infusion test (SIT), and diagnosis of PA between results judged by PAC(RIA) according to the previous guidelines and those judged by ePAC(CLEIA) according to the new guidelines. The results revealed discordant diagnosis rates of 6.4% for SC and 10.1% for CCT, with no discordance for SIT. The discordant diagnosis rate for PA was 3.7%. Our study reveals the challenges in establishing appropriate diagnostic criteria for PA using PAC(CLEIA) and highlights the demand for further research on provisionally positive categories.

  • Post-traumatic pituitary stalk transection syndrome (PSTS) expeditiously manifested after a fall from a height combined with acute traumatic spinal cord injury: a rare case report with review of literature.

     View Summary

    Post-traumatic pituitary stalk transection syndrome (PSTS) is an extremely rare cause of combined pituitary hormone deficiency (CPHD), affecting approximately 9 per 100,000 cases of traumatic brain injury. In contrast, pituitary stalk interruption syndrome (PSIS) is also a rare cause of CPHD. Importantly, these conditions are often confused due to their similar names and resembling findings on magnetic resonance imaging (MRI). PSIS has been thought to be a prenatal developmental event resulting from a couple of genetic aberrations. In typical PSIS, anterior pituitary hormone deficiencies are restricted to growth hormone (GH) and gonadotropin during the pediatric age, gradually and generally progressing to panhypopituitarism in most cases. In contrast, global deficiencies of the anterior pituitary hormones in PSTS are temporally associated with trauma. To the best of our knowledge, no case reports of PSTS combined with acute traumatic spinal cord injury have been reported. A 34-year-old female was transferred to our hospital after jumping from the fourth building floor. She was diagnosed as an acute traumatic spinal cord injury and underwent the operation of elective posterior spinal fusion. On postoperative day 7, the blood tests revealed considerable hyperkalemia, hyponatremia and eosinophilia. Notably, menstruation stopped after falling from a height. Pituitary function tests revealed GH deficiency, hypogonadism, hypothyroidism and hypoadrenocorticism. MRI revealed loss of the pituitary stalk, whilst the hyperintense signal from distal axon of hypothalamus was still identified. Based on these findings, she was diagnosed as PSTS. Our case highlights endocrinological landscape of transection of the pituitary stalk by acute trauma.
