ABSTRACT

Type 2 diabetes mellitus is commonly associated with cardiovascular, renal complications, osteoporosis and other comorbidities. Sodium-glucose co-transporter 2 inhibitor (SGLT-2i) can reduce blood glucose level in patients with type 2 diabetes mellitus by promoting urine glucose excretion, and has the effect of weight loss and blood pressure reduction. Large randomized controlled clinical trials have shown that SGLT-2i can improve the prognosis of cardiovascular disease and diabetic nephropathy. This article focuses on the effects of SGLT-2i on cardiorenal outcomes and bone metabolism in addition to the glucose-lowering effect. SGLT-2i can improve the prognosis of patients with coronary atherosclerotic cardiovascular disease, reduce the risk of hospitalization for heart failure, reduce cardiovascular diseases and all-cause mortality, and has renal protective effect. Moreover, the cardiorenal protective effect is proved to be consistent in people without type 2 diabetes. SGLT-2i has a regulatory effect on bone mineral ions and bone metabolism related hormones, and its risk of osteoporosis and fracture deserves attention. Although data suggest that canagliflozin may increase fracture risk, meta-analyses of multiple clinical trials have concluded that SGLT-2i does not significantly increase fracture risk. However, for patients with high risk of fracture, bone mineral density and bone turnover biomarkers should be considered to assess the risk of fracture before prescription.

ABSTRACT

Objective:To analyze the gene variants in patients with primary distal renal tubular acidosis (dRTA), and explore the correlation between the genotype and phenotype.Methods:The Sanger direct sequencing or whole-exome sequencing was used to identify causal variants and the variation pathogenicity was evaluated according to 2015 American College of Medical Genetics and Genomics (ACMG) standards and guidelines in 44 dRTA patients (37 families) diagnosed in the Affiliated Qingdao Municipal Hospital of Qingdao University and the Affiliated Hospital of Qingdao University from April 2010 to September 2020. The clinical features of the patients were summarized, and the correlation between the genotype and phenotype was investigated.Results:Seven variants of SLC4A1 gene, 17 variants of ATP6V0A4 gene, and 15 variants of ATP6V1B1 gene were identified in 44 patients with dRTA, and of which 11 variants were new ones. According to ACMG guidelines, the pathogenic, likely pathogenic, benign variants among the 39 variants were 22, 16 and 1, respectively. Nine patients were autosomal dominant hereditary dRTA caused by SLC4A1 gene mutation, 4 patients with autosomal recessive hereditary dRTA complicated with Southeast Asian ovalocytosis and anemia were caused by SLC4A1 gene mutation, and 14 patients caused by ATP6V0A4 gene mutation and 8 patients caused by ATP6V1B1 gene mutation were autosomal recessive hereditary dRTA; Two children with dRTA were found to carry one monoallelic defect in ATP6V1B1, and no causal gene mutation was identified in 7 patients. One patient showed incomplete dRTA, and the other 43 patients showed complete dRTA. The prevalence of sensory neural hearing loss caused by ATP6V0A4 and ATP6V1B1 mutation were 2/14 and 6/10 respectively. The frequency of chronic kidney disease in adults, children and infants were 4/4, 2/4, and 1/36, separately. After the drug treatment based on potassium citrate and sodium citrate, the growth and development (28/40) and electrolyte disturbance (41/44) of most patients were significantly improved. Conclusions:The present study has identified 39 variants of SLC4A1, ATP6V0A4 and ATP6V1B1 genes in 44 patients with dRTA, including 11 novel ones. There is a close relationship between genotype and phenotype in dRTA patients and most patients' conditions were improved after proper treatment. This study enriches the human gene mutation database and provides valuable references for diagnosis, treatment and genetic counseling in patients with dRTA.

ABSTRACT

Objective:To investigate the association of muscle mass loss with atherosclerosis in elderly patients with type 2 diabetes mellitus(T2DM).Methods:A total of 322 patients with T2DM aged≥60 years old were divided into muscle mass loss group( n=152) and non-muscle mass loss group( n=170) according to their appendicular skeletal muscle mass index(ASMI). All participants underwent physical examination, dual-energy X-ray absorptiometry check, carotid and lower extremity ultrasound, as well as laboratory tests. Results:Among 322 patients, 49(15.22%) patients were suffered from sarcopenia and 152(47.2%) patients with reduced muscle mass. The carotid and lower extremity atherosclerosis grades in the muscle mass loss group were significantly higher than those in the non-muscle mass loss group( P<0.05), with lower body mass index(BMI), T-score, ASMI, uric acid, and homeostasis model assessment of insulin resistance index( P<0.05). Multivariate logistic regression analysis showed that carotid atherosclerosis and lower extremity atherosclerosis were risk factors for muscle mass loss while BMI and 25-(OH)D 3 were protective factors for muscle mass loss. There existed a consistency in carotid atherosclerosis grade and lower extremity atherosclerosis grade of elderly patients with T2DM( P<0.01). Conclusion:Atherosclerosis has a predictive value for early sarcopenia in elderly patients with T2DM.

ABSTRACT

Objective:To explore the related factors of muscle mass loss in patients with type 2 diabetes mellitus, and to provide evidence for prevention of sarcopenia in type 2 diabetic patients.Methods:A cross-sectional survey was used to select type 2 diabetic patients admitted to the Department of Endocrinology, Affiliated Hospital of Qingdao University from January 2019 to August 2019. All subjects underwent dual-energy X-ray absorptiometry check. According to the diagnostic criteria of the Asian Working Group for Sarcopenia (AWGS), the subjects were divided into a muscle reduction group and a non-muscle reduction group. Data including age, gender, body mass index, course of disease, blood index, urinary albumin-creatinin ration (UACR), and appendicular skeletal muscle index (ASMI) were collected. The relevant clinical data of viscera fat/subcutaneous fat (VAT/SAT), percentage of abdominal fat/percentage of hip fat (A/G), grip strength, and pace were analyzed for the related factors of muscle mass loss in type 2 diabetic patients.Results:A total of 369 patients with type 2 diabetes were enrolled, including 42 patients with sarcopenia (an incidence rate of 11.38%), and 155 patients with reduced muscle mass (an incidence of 42.01%). Age, systolic blood pressure, high density lipoprotein-cholesterol, UACR, VAT/SAT, and A/G in the muscle reduction group were higher than those in the non-muscle reduction group ( P<0.05). The parameter of body mass index, homeostasis model assessment for insulin resistance, estimated glomerular filtration rate (eGFR), ASMI, and grip strength were lower in the muscle reduction group than in the non-muscle reduction group ( P<0.05). Multivariate logistic regression analysis showed age, UACR, A/G, and VAT/SAT were risk factors for muscle loss, body mass index, eGFR, and grip strength were protective factors for muscle mass reduction. Conclusion:It is of great practical significance for type 2 diabetic patients, especially those with advanced age, central obesity, low body mass index, low grip strength, low glomerular filtration rate, and high UACR to perform an early screening and to begin an early intervention.

ABSTRACT

To report the clinical, imaging and pathological feature of a case of primary hyperparathyroidism(PHPT) with multiple brown tumors whose complain was repeated epistaxis, and to conduct a retrospective analysis with relevant literatures. A postmenopausal middle-aged woman, with a history of joint pain, fracture, and kidney stone which were neglected due to the lack of specificity of symptoms for years, went to hospital due to repeated epistaxis. Laboratory results showed high blood calcium, hypophosphatemia, alkaline phosphatase(ALP), and parathyroid hormone(PTH) levels, as well as increased urinary calcium. Imaging examination showed systemically multiple brown tumors and extensive osteoporosis. Meanwhile an abnormal mass was found behind the right thyroid. Taking all findings into account, the diagnosis was made with PHPT, and the histopathology further confirmed that the lesion was a parathyroid adenoma. This case seems to be a rare case of multiple brown tumor caused by parathyroid adenoma, which compressed and destructed nasal blood vessels, thus induced a repeated nasal discharge. After resection of parathyroid adenoma, the patient experienced a transient hypocalcemia and PTH level elevation. After 5-month follow up, part of the brown tumors spontaneously regressed, bone density increased, and her clinical symptoms were mostly relieved.

ABSTRACT

Objective To identify the clinical manifestations, imaging findings, and genetic mutation characteristics in an uncommon case of adrenoleukodystrophy ( ALD) with adrenocortical dysfunction ( Addison's disease) as the first manifestation. Methods The clinical data of the proband and his family members were comprehensively collected, and ABCDl gene sequencing was meticulously performed for the proband and his mother using high-throughput sequencing method. Results The patient presented with systematical skin pigmentation accompanied by fatigue in early stage, arose stroke-like episodes manifested as a sudden loss of consciousness and incontinence induced by high fever, and followed by progressive unclear speech, unstable walking and worsening vision. Serum very long-chain fatty acid (VLCFA) concentration increased over normal range. The brain MRI showed an abnormal signal of the symmetric distribution of the bilateral corpus callosum. A new c. 874 876del GAG hemizygous variation in the patient's ABCD1 gene was detected, while his mother had a nucleotide heterozygous variation to this site . Conclusion The diagnosis of ALD requires a combination of clinical manifestations, imaging examination, and serum VLCFA levels, while the detection of ABCD1 gene mutations is considered to be the most reliable approach.
