Fulltext Glibenclamide induced chronic cholestasis simulating primary biliary cirrhosis: a case report

Ramanathan M, Wahinuddin S, Kew ST

Med J Malaysia, 1996 Mar;51(1):140-3.
PMID: 10967995

A 43-year-old lady with long standing non-insulin dependent diabetes mellitus on glibenclamide presented with cholestatic liver disease. Initially she was thought to have developed primary biliary cirrhosis (PBC). When she made a spontaneous recovery following the withdrawal of glibenclamide, it became obvious that the patient had been suffering from drug-induced chronic cholestasis (DICC). The subtle differences between PBC and DICC are highlighted.

Repaglinide versus glibenclamide treatment of Type 2 diabetes during Ramadan fasting

Mafauzy M

Diabetes Res Clin Pract, 2002 Oct;58(1):45-53.

This study compared treatment with a prandial glucose regulator (repaglinide) and a sulphonylurea (glibenclamide) in Muslim Type 2 diabetic patients who practice Ramadan fasting. Two hundred and thirty-five patients, previously treated with a sulphonylurea, were randomised to receive either repaglinide (n=116, preprandially three-times daily) or glibenclamide (n=119, preprandially once- or twice-daily) 6 weeks before Ramadan. During Ramadan, patients changed their eating pattern to two meals daily, and the daily dose of repaglinide was redistributed to two preprandial doses. After Ramadan, patients resumed their regular meal pattern and treatment dosage for 4 weeks. During Ramadan, a statistically significant reduction in mean serum fructosamine concentration from baseline was observed in the repaglinide group (-16.9+/-4.9 micromol/l, -3.8%, P<0.05) but not the glibenclamide group (-6.9+/-4.8 micromol/l, -0.8%). Difference in change in HbA(1c) from baseline was not statistically significant between groups. The number of hypoglycaemic events with midday blood glucose <4.5 mmol/l was significantly lower in the repaglinide group (2.8%) than the glibenclamide group (7.9%) (P=0.001). Apart from hypoglycaemia, both treatments were equally well tolerated. Type 2 diabetic Muslims using prandial repaglinide showed a trend towards better glycaemic control and had a lower frequency of hypoglycaemia than patients using glibenclamide during Ramadan.

Efficacy and safety of single versus multiple daily doses of glibenclamide in type 2 diabetes mellitus

Wan Mohamad WB, Tun Fizi A, Ismail RB, Mafauzy M

Diabetes Res Clin Pract, 2000 Aug;49(2-3):93-9.

Although long acting, glibenclamide is frequently given in split doses for type 2 diabetes mellitus. This may discourage compliance. It is thus appropriate to consider dosing it less frequently. We therefore studied glibenclamide effects when used once daily and when used in split doses. Our objective was to assess the feasibility of using once daily dosing as a regimen of choice. We measured plasma glucose, insulin, glibenclamide, lipids, HbAl and body mass index associated with the regimens. We also compared the number of hypoglycemic episodes occurring with them. Thirty type 2 diabetics on multiple daily glibenclamide were enrolled. Their regimens were changed over to once daily. Blood for glucose, insulin, lipids, HbAl and glibenclamide and body weight measurements were determined before and after the crossover period. We found no major difference in the sugar and insulin profiles with the two regimens. Fasting total cholesterol and triglyceride were also similar and so were plasma glibenclamide. The HbAl levels and body mass index and number of minor and major hypoglycemic episodes and hospital admissions for hypoglycemia also did not differ. We conclude that single daily dosing of glibenclamide was equivalent to multiple daily dose regimens. It can be used to an advantage to improve patient's compliance.

Early transition from insulin to sulfonylureas in neonatal diabetes and follow-up: Experience from China

PMID: 28791793 DOI: 10.1111/pedi.12560

BACKGROUND: Sulfonylurea therapy can improve glycemic control and ameliorate neurodevelopmental outcomes in patients suffering from neonatal diabetes mellitus (NDM) with KCNJ11 or ABCC8 mutations. As genetic testing results are often delayed, it remains controversial whether sulfonylurea treatment should be attempted immediately at diagnosis or doctors should await genetic confirmation.
OBJECTIVE: This study aimed to investigate the effectiveness and safety of sulfonylurea therapy in Chinese NDM patients during infancy before genetic testing results were available.
METHODS: The medical records of NDM patients with their follow-up details were reviewed and molecular genetic analysis was performed. Sulfonylurea transfer regimens were applied in patients diagnosed after May 2010, and glycemic status and side effects were evaluated in each patient.
RESULTS: There were 23 NDM patients from 22 unrelated families, 10 had KCNJ11 mutations, 3 harbored ABCC8 mutations, 1 had INS mutations, 4 had chromosome 6q24 abnormalities, 1 had a deletion at chromosome 1p36.23p36.12, and 4 had no genetic abnormality identified. Sixteen NDM infants were treated with glyburide at an average age of 49 days (range 14-120 days) before genetic confirmation. A total of 11 of 16 (69%) were able to successfully switch to glyburide with a more stable glucose profile. The responsive glyburide dose was 0.51 ± 0.16 mg/kg/d (0.3-0.8 mg/kg/d), while the maintenance dose was 0.30 ± 0.07 mg/kg/d (0.2-0.4 mg/kg/d). No serious adverse events were reported.
CONCLUSIONS: Molecular genetic diagnosis is recommended in all patients with NDM. However, if genetic testing results are delayed, sulfonylurea therapy should be considered before such results are received, even in infants with newly diagnosed NDM.
