Introduction: Hypoglycemia, a frequent and potentially life-threatening consequence of anti-diabetic therapy, remains a major barrier to optimal glycemic control. Effective inpatient management depends on frontline staff knowledge and preparedness; thus, knowledge gaps may compromise patient safety. This audit evaluated staff knowledge of hypoglycemia management in a district hospital in Malaysia to identify areas for improvement. Methodology: A cross-sectional audit was conducted among healthcare staff in a district hospital. A structured, modified questionnaire based on the Malaysian MEMS Inpatient Glycemic Guidelines was used. The 10-item questionnaire assessed definition, initial and subsequent management, reassessment, escalation, and documentation, yielding scores from 0 to 10. Descriptive statistics were used for analysis. Conclusion Despite high overall knowledge, critical gaps remain in reassessment, drug-related risks, and stepwise management, warranting targeted education, protocol reinforcement, and re-audit to enhance patient safety.

Introduction: Clinically important drug–drug interactions are a frequently overlooked cause of severe hypoglycemia in patients with type 2 diabetes mellitus (T2DM). Gliclazide is primarily metabolized via cytochrome P450 2C9 (CYP2C9), while fluconazole is a potent inhibitor of this enzyme.1,2 Concomitant administrations markedly increase gliclazide plasma concentration and prolong its hypoglycemic effect, substantially increasing the risk of severe and prolonged hypoglycemia. In some cases of refractory sulfonylureainduced hypoglycemia, octreotide may need to be considered early. Case: A 63-year-old Malay female with a 15-year history of T2DM on maximum-dose gliclazide (320 mg/day) presented with syncope and recurrent severe hypoglycemia 5 days after receiving a single oral dose of fluconazole 150 mg for a superficial fungal skin infection. Her other antidiabetic medications included metformin 1 g twice daily and vildagliptin 50 mg once daily. Her blood pressure on presentation was 151/74 mmHg, and her glucose level was 2.8 mmol/L. Her presentation was compounded by community-acquired pneumonia and acute kidney injury (estimated glomerular filtration rate 52 mL/min/1.73 m²). Biochemical evaluation excluded adrenal insufficiency, with normal serum cortisol (1,098 µg/dL), serum sodium (141 mmol/L), and serum potassium (4.6 mmol/L). Thyroid and liver function tests were normal. Despite repeated boluses of 50% dextrose and continuous infusion of 20% dextrose, recurrent hypoglycemia persisted for up to 48 hours after discontinuation of gliclazide, with glucose ranging from 1.7 to 5.1 mmol/L, reflecting prolonged sulfonylurea activity. Conclusion This case highlights a clinically significant yet preventable interaction between fluconazole and gliclazide, mediated through CYP2C9 inhibition, resulting in sustained hyperinsulinemic hypoglycemia. Gliclazide should be reduced or withheld prior to initiating fluconazole, and medication review should be performed at every consultation.

Introduction: Insulin autoimmune syndrome (IAS), or Hirata syndrome, is characterized by hyperinsulinemic hypoglycemia resulting from the presence of high titers of insulin autoantibodies (IAAs) in the absence of exogenous insulin. We present a rare case of IAS. Case: A 75-year-old female with underlying hypertension, dyslipidemia, and osteoporosis presented with symptoms suggestive of spontaneous hypoglycemia of 3 months duration. She was non-diabetic with no history of antidiabetic agents or exogenous insulin use. Notably, she had taken traditional medications 1 month prior to onset of symptoms. Her fasting blood glucose was 2 mmol/L. Serum insulin was significantly elevated at >1,000 iui/mL and serum C peptide was 2,950 pmol/L, consistent with hyperinsulinemic hypoglycemia. Blood sulfonylurea level was not available. Her complete blood count and renal and liver function were normal. Thyroid function test was normal, and a short corticotropin stimulation test showed adequate cortisol response. Computed tomography (CT) pancreas, endoscopic ultrasound and PET-CT scan with Galium-68 DOTATATE showed no evidence of insulinoma. Serum IAAs were raised at 175 IU/mL, which confirmed a diagnosis of IAS. The patient was managed with dietary modifications and advised for frequent, small meals with low glycemic index, incorporating oral raw cornstarch. She was also started on oral diazoxide 100 mg twice daily (3 mg/kg/day) due to persistent hypoglycemia. She responded well to diazoxide with no more spontaneous hypoglycemia, however, developed fluid retention which was managed with oral diuretics. Subsequently, we managed to taper and stop the diazoxide after 18 months of treatment. Patient remains well with no further episodes of hypoglycemia. Conclusion IAS may be triggered by medications or viral infections, occurs more frequently in people with autoimmune conditions, and shows genetic predisposition. However, as in our patient, IAS may be idiopathic, and the cause remains unknown. IAS is frequently self-limiting, and our patient experienced spontaneous remission with no further hypoglycemic episodes after discontinuation of treatment.

OBJECTIVES: To investigate the role of active glucose monitoring in preventing hypoglycemia during the perioperative period of gastrointestinal endoscopy in children with glycogen storage disease type Ⅰb (GSD-Ⅰb). METHODS: A retrospective analysis was performed for the clinical data of children with GSD-Ⅰb who were diagnosed and treated in Guangdong Provincial People's Hospital from June 2021 to August 2024. The effect of active glucose monitoring on hypoglycemic episodes during the perioperative period of gastrointestinal endoscopy was analyzed. RESULTS: A total of 14 children with GSD-Ⅰb were included, among whom there were 7 boys and 7 girls, with a mean age of 10.0 years. Among 34 hospitalizations, there were 15 cases of hypoglycemic episodes (44%), among which 6 symptomatic cases (1 case with blood glucose level of 1.6 mmol/L and 5 cases with blood glucose level of <1.1 mmol/L) occurred without active monitoring, while 9 asymptomatic cases (with blood glucose level of 1.2-3.9 mmol/L) were detected by active monitoring. The predisposing factors for hypoglycemic episodes included preoperative fasting (5 cases, 33%), delayed feeding (7 cases, 47%), vomiting (2 cases, 13%), and parental omission (1 case, 7%). Two children experienced two hypoglycemic episodes during the same period of hospitalization, and no child experienced subjective symptoms prior to hypoglycemic episodes. Treatment methods included nasogastric glucose administration (1 case, 7%), intravenous injection of glucose (14 cases, 93%), and continuous glucose infusion (4 cases, 27%). Blood glucose returned to 3.5-6.9 mmol/L within 10 minutes after intervention and remained normal after dietary resumption. CONCLUSIONS Active glucose monitoring during the perioperative period of gastrointestinal endoscopy can help to achieve early detection of hypoglycemic states in children with GSD-Ⅰb, prevent hypoglycemic episodes, and enhance precise diagnosis and treatment.

Diabetes mellitus (DM) is a major global health issue, with glycated hemoglobin levels serving as the gold standard for evaluating glucose level control in DM patients. However, it has limitations in reflecting glucose oscillations (i.e. glycemic variability, GV). Increasing evidence suggests that GV is closely related to the progression of diabetes complications and patient prognosis. As people realize the importance of avoiding hypoglycemia while achieving target glycated hemoglobin levels in treatment, the clinical significance of GV becomes more obvious. This article systematically reviewed the concept and connotation of GV, summarized the latest research on its role in the complications of diabetes, and revealed the biochemical and pathophysiological abnormalities caused by excessive glycemic oscillation, aiming to provide a theoretical basis for the risk warning and early intervention of DM patients.

Objective: To analyze the short-time efficacy of empagliflozin in the treatment of glycogen storage disease type Ⅰb (GSD Ⅰb). Methods: In this prospective open-label single-arm study, the data of 4 patients were collected from the pediatric department in Peking Union Medical College Hospital from December 2020 to December 2022. All of them were diagnosed by gene sequencing and had neutropenia. These patients received empagliflozin treatment. Their clinical symptoms such as height and weight increase, abdominal pain, diarrhea, oral ulcer, infection times, and drug applications were recorded at 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 12 months, and 15 months after treatment to assess the therapeutic effect. The liquid chromatography-tandem mass spectrometry method was used to monitor the changes in 1, 5-anhydroglucitol (1, 5AG) concentration in plasma. At the same time, adverse reactions such as hypoglycemia and urinary tract infection were closely followed up and monitored. Results: The 4 patients with GSD Ⅰb were 15, 14, 4 and 14 years old, respectively at the beginning of empagliflozin treatment, and were followed up for 15, 15, 12 and 6 months, respectively. Maintenance dose range of empagliflozin was 0.24-0.39 mg/(kg·d). The frequency of diarrhea and abdominal pain decreased in cases 2, 3, and 4 at 1, 2 and 3 months of treatment, respectively. Their height and weight increased at different degrees.The absolute count of neutrophils increased from 0.84×10⁹, 0.50×10⁹, 0.48×10⁹, 0.48×10⁹/L to 1.48×10⁹, 3.04×10⁹, 1.10×10⁹, 0.73×10⁹/L, respectively. Granulocyte colony-stimulating factor was gradually reduced in 1 patients and stopped in 3 patient. Plasma 1, 5 AG levels in 2 children were significantly decreased after administration of empagliflozin (from 46.3 mg/L to 9.6 mg/L in case 2, and from 56.1 mg/L to 15.0 mg/L in case 3). All 4 patients had no adverse reactions such as hypoglycemia, abnormal liver or kidney function, or urinary system infection. Conclusion: In short-term observation, empagliflozin can improve the symptoms of GSD Ⅰb oral ulcers, abdominal pain, diarrhea, and recurrent infection, also can alleviate neutropenia and decrease 1, 5AG concentration in plasma, with favorable safety.

Objective: To systematically evaluate the correlation between prenatal steroid exposure and hypoglycemia in late preterm neonates. Methods: Eight databases in either Chinese or English, including PubMed, the Cochrane Library, Embase, Medline, Scopus, CNKI, Wanfang and VIP, were searched to extract the studies on the correlation between prenatal steroid exposure and hypoglycemia in late preterm neonates published from the establishment of each database to December 2022. The Meta-analysis was performed using Stata 14.0 statistical software. Results: A total of 9 studies were included in this Meta-analysis, including 6 retrospective cohort studies, 2 prospective cohort studies and 1 randomized controlled trial (RCT) study, involving 9 143 premature infants. The Meta-analysis showed that prenatal steroid exposure increased the risk of late preterm neonatal hypoglycemia (RR=1.55, 95%CI 1.25-1.91, P<0.001). The similar correlation between prenatal steroid exposure and hypoglycemia in late preterm neonates was all found in the following subgroups: North America (RR=1.57, 95%CI 1.37-1.80, P<0.001), enrolling pregnant women with gestational diabetes (RR=1.62, 95%CI 1.26-2.08, P<0.001), A-grade literature quality (RR=1.43, 95%CI 1.14-1.79, P=0.002), criteria for hypoglycemia ≤40 mg/dl (1 mg/dl=0.056 mmol/L, RR=1.49, 95%CI 1.28-1.73, P<0.001), sample size of 501-1 500 (RR=1.69, 95%CI 1.19-2.40, P=0.003) and >1 500 (RR=1.65, 95%CI 1.48-1.83, P<0.001), steroid injection dosage and frequency of 12 mg 2 times (RR=1.66, 95%CI 1.50-1.84, P<0.001), the time interval from antenatal corticosteroid administration to delivery of 24-47 h (RR=1.98, 95%CI 1.26-3.10, P=0.003), unadjusted gestational age (RR=1.78, 95%CI 1.02-3.10,P=0.043) and unadjusted birth weight (RR=1.80, 95%CI 1.22-2.66, P=0.003). Meta-regression results showed that steroid injection frequency and dose were the main sources of high heterogeneity among studies (P=0.030). Conclusion: Prenatal steroid exposure may be a risk factor for hypoglycemia in late preterm neonates.
