BACKGROUND: In pediatric patients with steroid-sensitive nephrotic syndrome, recent trials have revealed that a 2-month, short-term steroid regimen is not inferior to an extended steroid course. However, the optimal duration of initial steroid therapy for adult steroid-sensitive minimal change disease (MCD) remains unclear. OBJECTIVES: The aim of present study was to evaluate the effectiveness of a 2-month, short-term steroid regimen in the treatment of adult steroid-sensitive MCD patients. METHOD: This was a prospective observational study. Adult patients with steroid-sensitive MCD (n = 35) who were initiated on a short-term steroid regimen between January 2015 and June 2016 were included. The details of the regimen are as follows: (1) prednisolone was administered at an initial dose of 0.8-1.0 mg/kg/day and continued for 4-6 weeks and (2) dosage was reduced to 0.5-0.6 mg/kg/alternate day and continued for 4 weeks. Control patients (n = 140), who were treated using conventional steroid administration, were selected from our previous adult MCD cohort. All patients fulfilled the following criteria: biopsy-proven MCD, age ≥20 years, first episode of nephrotic syndrome, and attainment of complete remission within 4 weeks. The following parameters of patients who received short-term treatment regimen and control patients were compared: any relapse and frequent relapse, adverse events caused by steroid treatment and cumulative steroid dose. RESULTS: Throughout the observation period (median: 17.3 months), 24 (68.6%) patients in the short-term group developed at least one relapse. The short-term regimen showed earlier occurrence of any relapse than the conventional regimen (adjusted hazard ratio [aHR] 2.45; 95% CI 1.51-3.97; p < 0.001), but there was no difference in frequent relapse (aHR 1.31; 95% CI 0.43-3.99; p = 0.63). None of the patients showed any symptoms of adrenal insufficiency after discontinuation of corticosteroids. The cumulative steroid dose during the observational period was significantly lower in the short-term group than in the conventional group. CONCLUSIONS: The short-term steroid regimen may represent an effective treatment option that ensures lower steroid exposure when treating adult steroid-sensitive MCD patients.

Severe hypocalcemia following denosumab treatment in a patient with secondary osteoporosis associated with primary sclerosing cholangitis Open Access

Yasuda Yoshinori, Iwama Shintaro, Arima Hiroshi

ENDOCRINE JOURNAL Vol. 66 ( 3 ) page： 271 - 275 2019

Language：English Publishing type：Research paper (scientific journal)

Primary sclerosing cholangitis (PSC) has been known as a cause of secondary osteoporosis, which often requires medication. Herein, we give the first report of a case of a 38-year-old man with fatigue and paralysis in both upper limbs who had been treated with denosumab for secondary osteoporosis associated with PSC. Since bisphosphonate (alendronate) was ineffective in our patient, the treatment was changed from alendronate to denosumab. Despite replacements with calcium and active vitamin D (alfacalcidol; 1-hydroxycholecalciferol), he developed severe hypocalcemia (albumin-adjusted serum calcium: 5.2 mg/dL) 2 weeks after the second administration of denosumab, which required immediate correction. After that, the corrected serum calcium levels were controlled within the normal range with 0.75 μg of eldecalcitol (1α,25-dihydroxy-2β-(3-hydroxypropyloxy)vitamin D3) and increased doses of calcium (1,500 mg daily) and phosphate (900 mg daily) without denosumab. Even though denosumab treatment had been terminated, the T score of the lumbar spine improved from -4.4 to -2.6 by 1 year after the second administration, possibly due to the amelioration of osteomalacia through the treatment with eldecalcitol and the higher doses of calcium and phosphate. This report indicates that denosumab can cause severe hypocalcemia in patients with osteoporosis associated with chronic diseases of the hepatobiliary system including PSC, in turn suggesting that the possibility of vitamin D deficiency or osteomalacia should be considered before administering treatments and that serum calcium levels should be closely monitored to detect life-threatening hypocalcemia in patients who have high risk factors for hypocalcemia.

Management of immune-related adverse events in endocrine organs induced by immune checkpoint inhibitors: clinical guidelines of the Japan Endocrine Society. Open Access

Immune checkpoint inhibitors (ICIs) have become a promising treatment for advanced malignancies. However, these drugs can induce immune-related adverse events (irAEs) in several organs, including skin, gastrointestinal tract, liver, muscle, nerve, and endocrine organs. Endocrine irAEs comprise hypopituitarism, primary adrenal insufficiency, thyroid dysfunction, hypoparathyroidism, and type 1 diabetes mellitus. These conditions have the potential to lead to life-threatening consequences, such as adrenal crisis, thyroid storm, severe hypocalcemia, and diabetic ketoacidosis. It is therefore important that both endocrinologists and oncologists understand the clinical features of each endocrine irAE to manage them appropriately. This opinion paper provides the guidelines of the Japan Endocrine Society and in part the Japan Diabetes Society for the management of endocrine irAEs induced by ICIs.

当院で傍鞍部腫瘍に対しeTSS(内視鏡下経鼻経蝶形骨手術)を施行した98例(男性50例、女性48例、平均年齢55.9歳)を対象に、術後の遅発性低Na血症(DHN)発症について検討した。その結果、DHNは37例(37.8%)に認められた。DHN発症患者ではDHN発症時のAVP分泌が抑制されていないことが確認された。また、術後7日目においてDHN非発症患者では約3%程度の体重低下を認めるのに対し、DHN発症例では体重減少は1%程度と軽微であり、体内への水分貯留が示唆された。術前より尿崩症が認められた患者群ではDHN発症が少なかったものの、DHN発症例では渇感中枢障害を伴っていた。これは術後の脱水を危惧したADH補充による医原性のものと考えられた。以上、傍鞍部腫瘍の術後DHNの発症にはSIADHが強く関与していることが考えられた。尚、術後早期からの水分制限はDHN発症予防に有効と考えられたが、より適切なプロトコールならびに予測法の確立が必要である。

Familial neurohypophysial diabetes insipidus (FNDI), characterized by progressive polyuria and loss of arginine vasopressin (AVP) neurons, is an autosomal dominant disorder caused by AVP gene mutations. Our previous studies with FNDI model mice demonstrated that mutant proteins accumulated in the endoplasmic reticulum (ER) of AVP neurons. Here, we examined therapeutic effects of the chemical chaperone 4-phenylbutylate (4-PBA) in FNDI mice. Treatment with 4-PBA reduced mutant protein accumulation in the ER of FNDI mice and increased AVP release, leading to reduced urine volumes. Furthermore, AVP neuron loss under salt loading was attenuated by 4-PBA treatment. These data suggest that 4-PBA ameliorated mutant protein accumulation in the ER of AVP neurons and thereby prevented FNDI phenotype progression.
