Effects of body mass index and estimated glomerular filtration rate on pituitary function in patients with non-functioning pituitary tumor

Seki Yasufumi , Ichihara Atsuhiro

Introduction: Hypothalamus or pituitary disorders frequently cause hypopituitarism. Diagnosing deficits of anterior pituitary hormones is important to manage metabolic impairments induced by hypopituitarism. Provocative tests including TRH, LHRH, CRH and GHRP-2 to diagnose hypopituitarism are recommended in Japan, however, the cut-off values in those tests are not adjusted for age, body mass index (BMI) or estimated glomerular filtration rate (eGFR). We retrospectively evaluat...

Renal prognosis of diabetic patients with and without central diabetes insipidus

Yatabe Junichi , Yatabe Midori , Babazono Tetsuya , Uchigata Yasuko , Ichihara Atsuhiro

Background: It has been suggested that higher arginine vasopressin (AVP) concentration may be associated with greater eGFR decline in diabetic patients not using inhibitors of the renin-angiotensin system (Diabetologia 2013). If excessive AVP action is detrimental to renal prognosis, then diabetic patients with central diabetes insipidus (CDI) may have relatively preserved renal function. Therefore, we aimed to compare long-term renal prognosis of diabetic patients with and wi...

A negative association between growth hormone secretion and inflammation in adult patients with non-functioning pituitary mass

Seki Yasufumi , Bokuda Kanako , Morimoto Satoshi , Watanabe Satoshi , Yamashita Kaoru , Takano Noriyoshi , Watanabe Daisuke , Ichihara Atsuhiro

Background: Growth hormone (GH) deficiency, which causes visceral obesity and non-alcohol fatty liver disease, increases cardiovascular event risks. High-sensitivity C-reactive protein (hs-CRP), an inflammatory marker associated with increased cardiovascular risk, reportedly decreased after GH supplementation in GH-deficient patients, however, the association between GH secretion and inflammation remains unclear.Patients and Methods: We retrospectively i...

Soluble (Pro)rennin receptor levels in patients with graves disease

Mizuguchi Yuki , Yatabe Midori , Yatabe Junichi , Seki Yasufumi , Niyama Michita , Bokuda Kanako , Watabnabw Daisuke , Ando Takashi , Morimoto Satoshi , Ichihara Atsuhiro

Background: (Pro)renin receptor[(P)RR] is a multi-functioning transmembrane protein which plays key roles in the regulation of tissue renin-angiotensin system (RAS). (P)RR is cleaved by furin to generate soluble (P)RR[s(P)RR], which is secreted into extracellular space. We previously reported that high blood concentration of s(P)RR indicates poor organ prognosis in several diseases. In this way, s(P)RR is expected as a candidate biomarker for reflecting the tissue RAS status, ...

Isolated pituitary sarcoidosis stained with a specific MAB against Propionibacterium acnes: a case report

Yamashita Kaoru , Niiyama Michita , Seki Yasufumi , Watanabe Daisuke , Isozaki Osamu , Amano Kosaku , Komori Takashi , Okada Yoshikazu , Eishi Yoshinobu , Ichihara Atsuhiro

Introduction: Sarcoidosis is a systemic granulomatous disorder usually affects multiple organs. Approximately 10% of sarcoidosis occurs as isolated neurosarcoidosis in CNS and <10% of neurosarcoidosis develops in a restricted hypothalamic–pituitary area. Recent study has identified Propionibacterium acnes in lungs and lymph nodes of many patients with sarcoidosis using a MAB specific for this bacterium (PAB), providing strong evidence for P. acne as ...

Effect of growth hormone deficiency on serum high-sensitivity C-reactive protein levels in adult patients with non-functioning pituitary tumors

Seki Yasufumi , Takano Noriyoshi , Yamashita Kaoru , Bokuda Kanako , Sasaki Nobukazu , Ishikawa Toru , Kimura Miwa , Watanabe Satoshi , Watanabe Daisuke , Morimoto Satoshi , Ichihara Atsuhiro

Background: Growth hormone (GH) deficiency causes visceral obesity and fatty liver and increases cardiovascular event risks. Because serum high-sensitivity C-reactive protein (hs-CRP) levels, which has been used to estimate those risks, was reported to be decreased by GH supplementation therapy in GH deficient patients, it has been suggested that inflammatory processes might be activated in GH deficient state. However, the clinical factors associated with increased hs-CRP leve...

(Pro)renin Receptor is essential for filtration barrier in glomerular podocyte

Kinouchi K. , Ichihara A. , Oshima Y. , Kurosawa H. , Sun-Wada G. , Wada Y. , Yamada T. , Takemoto M. , Saleem M. , Quaggin S. , Itoh H.

Backgrounds: Podocytes are highly specialized postmitotic kidney cells that contribute to maintaining the filtration barrier and normal structure of glomerular capillaries. The (pro)renin receptor (PRR), as ATP6AP2, is an accessory subunit of the vacuolar H+-ATPase (V-ATPase), implying more fundamental, developmental functions for the PRR in addition to its role in activating the local renin-angiotensin system.Results: Podocyte-specific conditional (P)RR...

Effectiveness of octoreotide administration before surgery for GH-TSH co-secreting pituitary adenoma with thyrotoxicosis: a case report

Kimura Shihori , Isozaki Osamu , Fukuda Izumi , Morimoto Satoshi , Seki Yasufumi , Yamashita Kaoru , Takano Noriyoshi , Otsuki Akiko , Kaneshige Terumi , Bokuda Kanako , Watanabe Daisuke , Ando Takashi , Hizuka Naomi , Amano Kosaku , Komori Takashi , Okada Yoshikazu , Ichihara Atsuhiro

Introduction: TSH-secreting pituitary adenoma (TSHoma) sometimes brings on rare cause of hyperthyroidism because of its excessive TSH secretion. Though the first line of treatment for TSHoma is surgical removal of tumour, hyperthyroidism often causes perioperative thyroid storm. Here, we report a case of GH-TSH pituitary adenoma whose thyrotoxicosis was controlled by 5 days’ octoreotide (OCT) subcutaneous administration before surgery.Case report: A...
