RESUMEN

@#The occurrence of hyperuricemia is frequently associated with diabetic ketoacidosis (DKA), however, crystalluria from the precipitation of calcium oxalate, uric acid, or urate crystals, is less known. Metabolic derangements during DKA, especially acidic urinary pH and hyperuricosuria are the main risk factors for uric acid crystals and stones. Here we report a case of uric acid crystalluria following the recovery phase of DKA.

Objective@#To evaluate the real-world use of once-weekly semaglutide among Thai patients with type 2 diabetes (T2DM) in a private hospital setting.@*Methodology@#A retrospective review of Thai patients with T2DM who have initiated semaglutide for at least 1 month between June 2020 and March 2022 at Theptarin Hospital, Bangkok, Thailand.@*Results@#A total of 58 patients (50% female, mean age 55.6 ± 15.9 years, with duration of diabetes 12.6 ± 10.3 years, BMI 31.5 ± 4.4 kg/m2, baseline HbA1c 7.9 ± 1.9%, with prior GLP-1 RA use 24.1%, and concomitant SGLT2i intake (41.4%) were included. During a median follow-up of 6 months, the mean serum HbA1c level reduction was 1.3 ± 1.7% with weight loss of 4.7 ± 4.1 kg. The proportion of patients who achieved optimal and sustainable glycemic control (HbA1c <7.0%) increased from 43.1% to 55.8% at the last follow-up. The proportion of patients reaching both HbA1c targets of <7.0% and 5% weight loss was 27.8%. No cases of pancreatitis, cancer, or progressive retinopathy were observed.@*Conclusion@#In this single center undertaking, it was shown that in among persons with T2DM and obesity in Thailand, semaglutide was associated with short-term glycemic control and weight loss comparable with what has been observed in randomized clinical trials and other RWE.

RESUMEN

The triad of diabetic ketoacidosis (DKA), severe hypertriglyceridemia, and acute pancreatitis have been occasionally described in severely obese patients with type 2 diabetes mellitus (T2DM). Herein, we present a long-term clinical course of a Thai man with ketosis-prone diabetes mellitus (KPDM) complicated with recurrent pancreatitis due to multifactorial chylomicronemia syndrome. Genetic testing showed no mutation in lipoprotein lipase (LPL) and its co-factors. The patient was referred to multidisciplinary team for lifelong weight loss consultation, limiting intake of fat and simple carbohydrates, and adherence to lipid-lowering medications. Subsequent follow-up 1 year later showed no recurrent pancreatitis. In patients with multifactorial chylomicronemia syndrome, long-term management with dietary modifications together with pharmacotherapy remains the cornerstone of successful treatment.

RESUMEN

Background: Weight gain post-radioiodine (RAI) treatment is observed in patients with hyperthyroid Graves' disease. Previous studies, mostly in Caucasian patients, demonstrated excessive weight gain averaging 5-7 kg from initial presentation. Aim: The aim of this study was to determine the extent and risk factors of weight gain in Thai patients with RAI-treated Graves' disease. Methods: This was a 5-year retrospective study of patients with hyperthyroid Graves' disease who received RAI treatment during 2016-2020. The proportion and associated risk factors of weight gain ≥5% in patients who was followed for at least 3 months when compared with weight at RAI administration were analyzed. Results: There were 347 patients with Graves' disease (females 81.0%, mean age 38.8 ± 12.1 years, BMI 23.3 ± 4.0 kg/m2) who were treated with RAI. Almost all RAI-treated patients (91.9%) eventually developed hypothyroidism. During the median follow-up period of 25 months, 73.1% of them had weight gain. The mean weight change was +2.5 ± 4.9 kgs when compared with weight at the time RAI administration and +3.4 ± 6.5 kgs when compared with recalled body weight before the onset of hyperthyroidism. The proportion of patient in the obesity class I (BMI 25.0-29.9 kg/m2) increased from 23.6% to 28.0% and obesity class II (BMI ≥30.0 kg/m2) increased from 5.2% to 8.9%. Duration of antithyroid drug treatment less than 6 months after the diagnosis of hyperthyroidism was the only factor associated with weight gain ≥5%. Conclusions: Weight gain post-RAI treatment was common, and a significant proportion of patients went on to develop obesity. Early intervention with weight management support should be employed in patients with less than 6 months of antithyroid drug treatment before RAI.

RESUMEN

Objective@#To evaluate the status of euthyroidism achieved among Thai patients with post-ablative hypothyroidism and to examine the difference between various weight-based daily levothyroxine (LT4) replacement regimens in these patients.@*Methodology@#We conducted a retrospective review of Thai patients with Graves’ disease (GD) who developed hypothyroidism following radioactive iodine treatment from 2016 to 2020 at Theptarin hospital. Daily LT4 dose was calculated based on actual body weight (ABW), ideal body weight (IBW), and estimated lean body mass (LBM).@*Results@#We reviewed a total of 271 patient records. Of these, 81.2% were females with a mean age of 40.8±11.7 years, LT4 intake duration of 27.1±14.6 months, and LT4 dose/kg ABW of 1.4±0.5 μg/kg/day. At the final follow-up, 62.4% of patients achieved thyroid-stimulating hormone (TSH) levels within the reference interval, 15.5% had TSH levels over, and 22.1% had TSH levels under the reference range. Obese patients required a lower daily LT4 dose relative to ABW and higher daily LT4 dose relative to IBW to attain euthyroidism (ABW 1.1±0.4 μg/kg/day and IBW 2.0±0.8 μg/kg/day). Estimated daily LT4 dose based on LBM showed a constant dosage of 2.0 μg/kg/day in all BMI categories.@*Conclusions@#Suboptimum LT4 replacement therapy was found in almost half of hypothyroid patients with GD treated with radioactive iodine. Estimated LBM was a better indicator for dosing calculation in these patients compared with ABW and IBW.

RESUMEN

@#Untreated celiac disease (CD) leads to an increased risk for hypoglycemia and diabetic complications. However, the diagnosis of CD can be challenging and some extra-gastrointestinal tract manifestations could be a presenting symptom. We report a case of a 29-year-old Indian male with brittle T1DM whose underlying CD was discovered from a work-up for anemia. After an introduction of a gluten-free diet, he gained 5 kgs in two months, was responsive to oral iron supplement, and had stable glycemic control with much less hypoglycemia. Even though this disease is rare in Asian populations, the diagnosis of celiac disease should always be kept in mind when people with T1DM present with unexplained microcytic anemia and/or unexplained hypoglycemia.

RESUMEN

@#Objectives. To describe the characteristics of long-standing T1DM in Thai patients and assess residual beta-cell function with status of pancreatic autoantibodies. Methodology. This is a cross-sectional study of Thai subjects with T1DM and disease duration ≥ 25 years seen at the Theptarin Hospital. Random plasma C-peptide and pancreatic auto-antibodies (Anti-GAD, Anti-IA2, and Anti-ZnT8) were measured. Patients who developed complications were compared with those who remained free of complications. Results. A total of 20 patients (males 65%, mean age 49.4±12.0 years, BMI 22.5±3.1 kg/m2, A1C 7.9±1.6%) with diabetes duration of 31.9±5.1 years were studied. Half of the participants remained free from any diabetic complications while the proportions reporting retinopathy, nephropathy, and neuropathy were 40%, 30%, and 15%, respectively. HDL cholesterol was significantly higher and triglyceride concentration significantly lower in patients who were free from diabetic nephropathy but not in those who were free from other complications. The prevalence rates of anti-GAD, anti- IA2, and anti-ZnT8 were 65%, 20%, and 10%, respectively. None of the patients who tested negative for both anti-GAD and anti-IA2 was positive for anti-ZnT8. Residual beta-cell function based on detectable random plasma C-peptide (≥ 0.1 ng/mL) and MMTT was found in only 3 patients (15%). There was no relationship between residual beta-cell function and protective effects of diabetic complications. Conclusion. Endogenous insulin secretion persists in some patients with long-standing T1DM and half of longstanding T1DM in Thai patients showed no diabetic complications. HDL cholesterol was significantly higher and triglyceride concentration significantly lower in patients who were free from diabetic nephropathy

RESUMEN

BACKGROUND: Advance in medicine has led to an increase in life expectancy of elderly diabetic patients especially on the growing population called the "oldest old", those in their mid-80s upwards. The aim of this study is to describe clinical characteristics and outcomes of "oldest old" patients in a specialized diabetes center. METHODS: A retrospective review was conducted on medical records of type 2 diabetes who were older than 85 years at Theptarin hospital from September 2014 to August 2015. RESULTS: During the study period, there were 143 oldest old diabetic patients who visited our hospital regularly. Of the 133 active follow-up patients (median time of follow-up 15 years, range 1-30 years), 70.7 % was female, the mean age of onset was 68.3 ± 11.5 years and duration of diabetes was 20.1 ± 11.1 years. According to the Charlson co-morbidity index (CCI), 35.3 % of patients were classified as having severe co-morbidities. The mean A1C, blood pressure, LDL were 6.7 ± 1.1 %, 132/65 mmHg and 80 ± 29 mg/dl respectively. 66.9 % of patients had tight glycemic control (A1C <7 %) while 12.0 % had poor control (A1C >8 %). Oral hypoglycemic agent (OHA) dual therapy was the most common treatment (26.3 %) followed by OHA monotherapy (22.6 %), insulin alone (19.5 %), diet therapy alone (12.7 %), and insulin plus OHA (8.3 %). Hypoglycemia was found in 10.5 % of patients in previous 12 months. Diabetic retinopathy, chronic kidney disease, cardiovascular disease, and stroke were presented in 23.4, 54.9, 15.8, 18.0 % of patients, respectively. Among patients whose received diabetic medications and resulted in very low level of A1C (A1C less than 6.0 %), only 20.0 % underwent deintensification. CONCLUSIONS: Our results revealed that real-world clinical outcomes of extreme elderly diabetic patients were diverse and being too "aggressive" diabetes treatment with older patients did occur frequently. Decision making in older people with diabetes is complex as chronic co-morbidities are very common.

RESUMEN

BACKGROUND: Ketosis-prone diabetes (KPDM) is new-onset diabetic ketoacidosis without precipitating factors in non-type 1 diabetic patients; after management, some are withdrawn from exogenous insulin, although determining factors remain unclear. METHODS: Twenty KPDM patients and twelve type 1 diabetic patients (T1DM), evaluated at baseline, 12 and 24 months with/without insulin maintenance underwent a standardized mixed-meal tolerance test (MMTT) for 2 h. RESULTS: At baseline, triglyceride and C3 were higher during MMTT in KPDM vs. T1DM (p<0.0001) with no differences in non-esterified fatty acids (NEFA) while Acylation Stimulating Protein (ASP) tended to be higher. Within 12 months, 11 KPDM were withdrawn from insulin treatment (KPDM-ins), while 9 were maintained (KPDM+ins). NEFA was lower in KPDM-ins vs. KPDM+ins at baseline (p = 0.0006), 12 months (p<0.0001) and 24 months (p<0.0001) during MMTT. NEFA in KPDM-ins decreased over 30-120 minutes (p<0.05), but not in KPDM+ins. Overall, C3 was higher in KPDM-ins vs KPDM+ins at 12 months (p = 0.0081) and 24 months (p = 0.0019), while ASP was lower at baseline (p = 0.0024) and 12 months (p = 0.0281), with a decrease in ASP/C3 ratio. CONCLUSIONS: Notwithstanding greater adiposity in KPDM-ins, greater NEFA decreases and lower ASP levels during MMTT suggest better insulin and ASP sensitivity in these patients.
