Diabetes mellitus (DM) is a complex endocrine disorder characterized by abnormally high levels of glucose, also called hyperglycemia. DM usually occurs when the body does not produce enough insulin or cannot respond to the insulin in the body. Type 1 diabetes mellitus (T1DM) or insulin-dependent diabetes is an autoimmune disease that affects around 8 million people in the world. Patients with T1DM experience an array of symptoms such as polyuria, polydipsia, and weight loss. These patients are prone to immediate life-threatening complications, including hypoglycemia and diabetic ketoacidosis. These patients are also at increased risk of ischemic heart disease, stroke, chronic kidney disease, vision loss, and even damage to nerve endings resulting in neuropathy. In this article, we will discuss type 1 diabetes mellitus and the different treatment options, focusing primarily on the Food and Drug Administration (FDA)-approved first cellular therapy for T1DM, donislecel.

AIMS
To provide an overview of reported cases of new-onset type 1 diabetes mellitus (T1D) following COVID-19 infection.
METHODS
PubMed and Scopus library databases were screened for relevant case reports published between January 2020 and June 2022. Study design, geographic region or language were not restricted.
RESULTS
Twenty studies were identified and involved 37 patients (20 [54%] male, 17 [46%] female). Median age was 11.5 years (range 8 months-33 years) and 31 (84%) patients were aged ≤17 years. Most patients (33, 89%) presented with diabetic ketoacidosis (DKA). In total, 23 (62%) patients presented at the time of positive COVID-19 testing and 14 (38%) had symptoms consistent with COVID-19 infection or a previous positive test (1-56 days). Diabetes symptomatology was provided in 22 cases and (19, 86%) reported polyuria, polydipsia, polyphagia, fatigue, or weight loss or a combination of the aforementioned in the preceding weeks (3 days-12 weeks). Of the 28 patients that had data on acute and long-term treatment, all recovered well and most were managed with basal bolus insulin regimens. Quality assessment showed that most reports were either 'good' or 'moderate quality'.
CONCLUSIONS
Although uncommon, new-onset T1D is a condition healthcare professionals may expect to see following a COVID-19 infection.

Pituitary-dependent hypersomatotropism is rarely diagnosed in dogs and surgical treatment is not reported. A 6-year-10-month male neutered Patterdale Terrier presented with polyuria, polydipsia, progressive pharyngeal stertor, excessive hair growth and widened facial features and paws. Serum insulin-like growth factor-1 concentration via radioimmunoassay was consistent with hypersomatotropism (1783 ng/mL). A pituitary mass was identified on magnetic resonance and computed tomography imaging. Six weeks later, glucosuria, starved hyperglycemia and serum fructosamine above the reference range (467.6 μmol/L, RI 177-314) were documented, consistent with diabetes mellitus. Transsphenoidal hypophysectomy was performed under general anesthesia without complications. Pituitary histopathology identified an acidophil neoplasm, with positive immunostaining for growth hormone. Postoperatively, there was rapid resolution of clinical, biochemical and morphologic changes of hypersomatotropism with persistence of diabetes mellitus. This case demonstrates successful resolution of hypersomatotropism with ongoing diabetes mellitus in a dog after surgical treatment by transsphenoidal hypophysectomy.

A 16-month-old neutered male domestic shorthair cat weighing 2.7 kg was referred for further evaluation of acute generalized muscle weakness and paraparesis after a long-standing history of polyuria-polydipsia. The diagnosis of hypodipsic/adipsic hypernatremia relied on the key findings of absent spontaneous drinking despite hypernatremia and a hyperosmolar state (444.8 mOsm/kg, reference interval 280 to 310 mOsm/kg). Brain MRI revealed severe multifocal anatomic anomalies of the rostral calvarium and the forebrain, suggestive of encephaloclastic porencephaly. Involvement of the thalamic and hypothalamic regions could have been responsible for the cat's adipsic hypernatremia. The unique aspects of this case were the rare description of central nervous system disease leading to hypodipsia, and the history of chronic polydipsia before the acute onset of hypodipsia. Key clinical message: Multifocal abnormalities of the forebrain can present with polyuria-polydipsia syndrome, hypodipsia/adipsia, or both, depending on the stage of the disease. This likely happens when the hypothalamic and thalamic regions are affected, since they regulate antidiuretic hormone release and thirst, respectively.

A 21-year-old woman presented with polyuria, fragility fractures, and a history of recurrent renal calculi, which was also present in her maternal aunt. Examination revealed an oval palpable mass in the neck. Biochemistry revealed a grossly elevated serum calcium, PTH, and serum alkaline phosphatase with low serum phosphorous, suggestive of primary hyperparathyroidism. Ultrasonography of the neck and parathyroid scintigraphy localized a large lesion arising from the right posterior and inferior aspect of the thyroid gland, suggesting a parathyroid tumor. Parathyroid carcinoma was suspected based on the severe clinical manifestations. A computed tomography scan of the abdomen revealed cysts in the kidneys, bilateral medullary nephrocalcinosis, left ectopic-pelvic kidney, and lytic lesions in the iliac bone. The patient underwent a right inferior parathyroidectomy with normalization of serum calcium postoperatively. Histopathologic examination revealed a parathyroid adenoma, which was contrary to the expectation. Whole exome sequencing in the index case revealed a novel 99-bp heterozygous insertion, likely pathogenic variant in the exon 2 of CDC73 gene causing hyperparathyroidism jaw tumor syndrome. Here, we report a rare case of hyperparathyroidism jaw tumor syndrome that presented with severe hypercalcemia, renal cysts, and an ectopic-pelvic kidney without jaw tumor or uterine abnormalities.

Bartter syndrome type 1 is caused by mutations in the solute carrier family 12 member 1 (), encoding the sodium-potassium-chloride cotransporter-2 (NKCC2). In addition to causing renal salt-losing tubulopathy, mutations are known to cause nephrocalcinosis due to hypercalciuria, as well as failure to thrive associated with abnormal calcium and phosphorus homeostasis. We report a now 7-year-old Japanese girl with polyuria, hyponatremia, hypokalemia, and metabolic alkalosis, in whom compound heterozygous novel mutations were identified. Elevated parathyroid hormone (PTH) levels were consistently noted after the age of 1 year in conjunction with gradually declining serum calcium and increasing serum phosphorus levels. To confirm suspected PTH-resistance, Ellsworth Howard tests were performed at the ages of 6 years 8 months and 6 years 10 months in the absence or presence of ibuprofen, respectively. Urinary adenosine 3',5'-cyclic monophosphate excretion increased on both occasions in response to PTH(1-34) infusion suggesting pseudohypoparathyroidism type II. However, only during treatment with ibuprofen did PTH induce an almost normal phosphaturic response. The nonsteroidal anti-inflammatory drugs thus enhanced growth velocity, alleviated hypercalciuria, and increased PTH-stimulated urinary phosphorus excretion without significantly affecting renal function.

Diabetes mellitus is one of the most common diseases worldwide and is a major cause of morbidity and mortality. Type 2 diabetes, with its hallmark being insulin resistance, constitutes the majority of cases. Although usually related to modifiable risk factors, insulin resistance can have genetic causes. Here, we present one of the rare causes of insulin resistance. A 21-year-old man, who was deaf and blind, presented with a 3-week history of polyuria and polydipsia. He was found to have significant hyperglycemia, managed initially with insulin infusion, then he was transitioned to subcutaneous injections. Because he required high doses of insulin and had acanthosis nigricans, insulin resistance was suspected. Putting together his insulin resistance and chronic history of syndromic features, Alström syndrome was considered. Genetic testing revealed a mutation in the gene. The patient was then started on insulin sensitizers with a tapering of insulin with good response. Insulin resistance should be suspected if the insulin requirement is high and if acanthosis nigricans is present. Alström syndrome is a rare causes of insulin resistance. Affected individuals will usually have insulin-resistant diabetes by a young age and associated blindness and deafness. Insulin sensitizers are an important part of the treatment.

Hereditary central diabetes insipidus (CDI) is a genetic disorder characterized by polydipsia and polyuria. Most known mutations are located in the arginine-vasopressin () gene. Here, we describe a Swiss family with an autosomal dominant mutation in the gene region encoding for the carrier protein neurophysin II (P55R). In addition, we discuss the algorithm for diagnosing and treating patients with hereditary CDI based on this Swiss family.

BACKGROUND/AIM
Effect predictors of desmopressin for nocturia associated with nocturnal polyuria are understudied. Herein, we investigated the effects of desmopressin on sleep and patient quality of life. We defined cases in which administration of desmopressin led to hours of undisturbed sleep (HUS) ≥3 hours as "marked response cases" and examined predictive factors of desmopressin treatment response.
PATIENTS AND METHODS
Our study included 129 patients who were administered desmopressin 50 μg for nocturia associated with nocturnal polyuria at our hospital. Efficacy and safety of desmopressin were examined using bladder diaries, International Prostate Symptom Score, Overactive Bladder Symptom Score, Athens Insomnia Scale, Patient Global Impression of Improvement (PGI-I) score, physical examinations, blood tests, and body composition analyzers, and the predictors of desmopressin efficacy were investigated.
RESULTS
Significant improvements in all endpoints were observed from the early stage onward after desmopressin treatment compared with before treatment. After treatment, HUS was significantly longer in patients with good PGI-I scores, which indicated patient satisfaction. Variation in nocturnal micturition frequency did not affect the improvement in patient satisfaction. Examination of cases defined as "marked response cases" showed that the mean night-time urine volume was an independent predictor of treatment response.
CONCLUSION
Desmopressin can improve patients' quality of life and sleep by extending HUS. This suggests that desmopressin may be effective in patients with high mean night-time urine volumes based on their bladder diary.

Ifosfamide, a cytotoxic antineoplastic drug, can induce rare complications of Fanconi syndrome and nephrogenic diabetes insipidus (DI). Ifosfamide-induced Fanconi syndrome tends to occur in patients with certain risk factors including young age, high cumulative ifosfamide dose, and coadministration of cisplatin. Nephrogenic DI causes polyuria from impaired urinary concentrating ability due to resistance to arginine vasopressin (AVP) at the collecting duct. These complications are serious and potentially fatal. Here, we describe a case of a middle-aged man without risk factors who was admitted for the management of acute kidney injury and electrolyte derangements after his fourth cycle of chemotherapy including ifosfamide for synovial sarcoma. He was found to have hypokalemia, hypophosphatemia, renal glycosuria, and aminoaciduria, likely from Fanconi syndrome, which were managed by electrolyte replacement therapy. In addition, polyuria and hypernatremia were considered due to nephrogenic DI, which partially responded to desmopressin treatment. This case highlights the importance of the routine electrolytes monitoring after ifosfamide treatment.
