It is caused by inadequate production of antidiuretic hormone, in response to hypothalamic osmoreceptor-stimulation, from the pituitary gland (central DI) or resistance to its action at terminal distal convoluted tubules and collecting ducts (nephrogenic DI). Most cases of nephrogenic DI are caused by drugs, especially chronic lithium use. The Case: A 46-year-old man manifested such a disorder 8 months following d-Penicillamine (d-P) therapy for cystinuria. The drug was discontinued and the patient was managed conservatively with high fluid intake, diet low in protein and salt as well as alkalization of urine with Urolyte U to a pH > 7.5. Six weeks later, such side effect disappeared. Our patient had developed such phenomenon: a) without significant liver or renal disease to account for cumulative toxicity, and b) with a conventional dosage range of d-P. Such isolated toxicity indicates inherited a predisposition to this side effect. Conclusion: DI is a potential side effect of d-P therapy that is nephrogenic in site, transient in prognosis and an isolated phenomenon likely to reflect genetic predisposition.展开更多

Up tonow, there are few reports about CNDI in neonates. Early clinical manifestationsof CNDI in neonates are atypical. A lack of understanding of the disease byclinicians causes frequent misdiagnoses or missed diagnoses, which may result infailure to administer treatments in time and ultimately leads to severecomplications. In this study, clinical data of a case of AVPR2 gene mutationinducedCNDI, which was confirmed by genetic testing, were retrospectivelyanalyzed to improve our understanding of this disease.CASE SUMMARY On February 1, 2020, a male neonate was hospitalized 17 d after birth due to a 7 dperiod of pyrexia. The patient’s symptoms included recurrent pyrexia,hypernatremia and hyperchloremia, which were difficult to treat. The patient wasfed on demand, and water was additionally provided between milk intakes. Acombination treatment of hydrochlorothiazide and amiloride was administered.After the treatment, body temperature and electrolyte levels returned to normal,the volume of urine was significantly reduced and the patient was subsequentlydischarged. Genetic tests confirmed that the patient carried the AVPR2 genemissense mutation c.541C>T (P.R181C), and the patient’s mother carried aheterozygous mutation at the same locus. After clinical treatment with acombination of hydrochlorothiazide and amiloride, the body temperature andelectrolyte levels returned to normal. Up until the most recent follow-up examination, normal body temperature, electrolyte levels and growth anddevelopment were observed.CONCLUSION CNDI in the neonatal period is rare, and its clinical manifestations are unspecificwith some patients merely showing recurrent fever and electrolyte disturbance.Genetic testing of AVPR2 and AQP2 can be used for screening and geneticdiagnosis of CNDI.展开更多

Gestational Diabetes Insipidus (GDI) can coexist with severe preeclampsia and HELLP syndrome. The combination of these two conditions presents a unique challenge to the anesthesiologist and the obstetric team, caring for this parturient. We present the case of a parturient with an unusual presentation of GDI, coexisting with severe preeclampsia and HELLP syndrome. She had two days history of polyuria and polydipsia as well as lethargy and rapidly rising serum sodium in addition to acute renal failure without any neurologic symptoms. Expeditious delivery of the baby and supportive management is essential for optimal outcomes. She underwent a repeat Cesarean section under combined spinal epidural (CSE) anesthesia. This patient was discharged on postoperative day five after clinical resolution of her signs and symptoms.展开更多

The result was compared with the database sequence to identify the mutable sites via a BLAST search, the incidence of every mutation was analyzed, and the putative transcription factor binding sites that maybe disturbed were analyzed by MAPPER. Mutation g.1394A>G in exon 3 of AVPR2 was detected in all the subjects, g.861C>T(S167L) in exon 2 of AVPR2 and IVS1+3G>A in intron of AQP2 were detected, respectively, in two patients, and c.836A>C in 3′ untranslated region of AQP2 was detected in two patients and one mother. Four mutations were identified. g.1394A>G of AVPR2 and c.836A>C of AQP2 have high incidence in patients with nephrogenic diabetes insipidus. Detection on the two sites may become auxiliary diagnosis index of congenital nephrogenic diabetes insipidus.展开更多

This paper reports the case of a 13 year-old boy who underwent surgery for a suprasellar tumour and, immediately after surgery, developed a cerebral abscess, persistent diabetes insipidus (DI) as well as cerebral salt wasting syndrome (CSWS). The early onset of CSWS following DI has been associated with a poor prognosis and increased mortality. In cases in which these abnormalities coexist, the increased polyuria secondary to the rise in natriuresis associated with CSWS might be erroneously interpreted as a sign of poor control of the DI, thereby leading to therapeutic mistakes. Treatment basically consists of restoring electrolytes and the joint administration of desmopressin and fludrocortisone.展开更多

The aim of this study is to determine the etiology of initial symptom presentation and the outcomes of visual impairment and DI in suprasellar region germinoma. Methods: We investigated eleven cases of single lesion suprasellar germinomas that were diagnosed and treated in our hospital. For each, a magnetic resonance imaging (MRI) was performed. Results: At the hospital visit, decreased visual acuity was found in 5/11 cases, while DI was found in all cases. The decreased visual acuity was improved in 4/5 cases by treatment, but DI improved in only 2/11 cases. In 10 cases, DI occurred earlier than visual impairment. As the initial symptom, visual impairment occurred earlier than DI in only one case and did not improve by treatment. In this case, a pituitary stalk of the normal thickness could be identified by MRI, and the optic nerve was swollen. In ten cases except this case, no significant enlargement of optic nerve was detected, and a swollen pituitary stalk was confirmed. Conclusions: In suprasellar germinomas, it is rare, but the optic nerve can significantly swell at onset, while the pituitary stalk may be intact. In such cases, visual impairment occurs earlier than DI, and visual impairment may not be improved.展开更多

She was primigravida, with normal past medical history. Fasting blood levels were normal;specific gravity of the urine: 1006;no glucosuria or proteinuria was present. Urinary and plasma osmolality were 245 and 287 mOsm/l;water intake about 2700mL/day;diuresis 2000mL/day. On the basis of the value of urine output and osmolality the dose of desmopressin was Increased at 40 mg/nostril/day. Patient was evaluated every month with fluid balance, urine volume, osmolality, and serum electrolytes. Daily dosage of desmopressin was 40mg/nostril for all the duration of pregnancy according to a trend of an adequate fluid and electrolytes balance and in absence of symptoms. Mean blood Pressure was 100/60 mmHg;coagulation, liver, renal function were normal. Fetal monitoring with periodic ultrasound detected a normal intrauterine growth. Patient had an uncomplicated labor of a healthy male baby at the 39th week. Because of an insufficient dilatation of the cervical canal caesarian section was chosen. Despite a previous Central Diabetes Insipidus may worsen in a pregnant with impaired reserve of Antidiuretic Hormone because of the changes in osmoregulatory system and increased levels of vasopressinasis in middle and late pregnancy, our patient required a slightly higher dose of desmopressin in the first trimester. Contrary to expectations the need of desmopressin did not increase during the weeks.展开更多

文摘Background: Diabetes insipidus (DI) is a rare disorder characterized by inappropriate polyuria and hypo-osmolar urine. It is caused by inadequate production of antidiuretic hormone, in response to hypothalamic osmoreceptor-stimulation, from the pituitary gland (central DI) or resistance to its action at terminal distal convoluted tubules and collecting ducts (nephrogenic DI). Most cases of nephrogenic DI are caused by drugs, especially chronic lithium use. The Case: A 46-year-old man manifested such a disorder 8 months following d-Penicillamine (d-P) therapy for cystinuria. The drug was discontinued and the patient was managed conservatively with high fluid intake, diet low in protein and salt as well as alkalization of urine with Urolyte U to a pH > 7.5. Six weeks later, such side effect disappeared. Our patient had developed such phenomenon: a) without significant liver or renal disease to account for cumulative toxicity, and b) with a conventional dosage range of d-P. Such isolated toxicity indicates inherited a predisposition to this side effect. Conclusion: DI is a potential side effect of d-P therapy that is nephrogenic in site, transient in prognosis and an isolated phenomenon likely to reflect genetic predisposition.
文摘Introduction:Central Diabetes insipidus(CDI)is a rare disorder caused by vasopressin deficiency characterized by the excretion of copious volumes of unconcentrated urine.Objective:To assess the etiological,clinical,biochemical and radiological spectrum of Central DI in our institute and long term follow up of these cases.Material and Methods:32 patients with Central DI admitted in Department of Endocrinology,Guwahati Medical College,Assam in the last 2.5 years were included.Detailed clinical assessment,biochemical evaluation and MRI(Magnetic Resonance imaging)brain were done in all the patients.Central DI without any identifiable cause was considered Idiopathic and those with structural lesion in hypothalamic pituitary region were considered organic.Result:Idiopathic CDI was present in 12(37.5%)patients and 20(62.5%)patients had organic CDI with acute onset of presentation.12(60%)patients with organic CDI present with neurological symptoms but 8(40%)patients had no neurological symptoms even with organic cause.Pituitary dysfunction was common in organic CDI as compared to idiopathic CDI.Paediatric patients commonly present with organic cause for CDI with low cortisol most common hormonal deficit.One patient of idiopathic CDI with normal stalk thickness at baseline presented with clinical and radiological features of LCH(Langerhans cell histiocytosis)on follow up.Conclusion:Organic CDI more likely to have acute onset of presentation than idiopathic CDI and even in absence of neurological features.Paediatric patients commonly have organic cause for CDI.We propose the paramount importance of long-term clinical follow-up and reassessment of endocrine function in patients with CDI for definitive diagnosis of autoimmune and inflammatory causes of idiopathic CDI and timely treatment of pituitary hypofunction.

文摘BACKGROUND Germinoma is a type of germ cell tumor that most frequently arises in the midline axis of the brain.Impaired vision is a clinical manifestation of germinnoma.Although rare,intracranial germinoma seeding to the perioptic arachnoid space is one cause of visual acuity decrease.CASE SUMMARY An 11yearold girl who presented with polyuria and polydipsia and subsequently developed diminution of vision.Imaging showed bilateral heterogeneous enhancement of the optic nerve sheaths and atrophy of the optic nerve,and transsphenoidal biopsy revealed a germinoma.The patient experienced poor visual recovery following chemotherapy and radiotherapy.Germinomas are rare and they are mostly identified in children and adolescents.The manifestations include diabetes insipidus,pituitary dysfunction,visual complaints,etc.The mechanisms that lead to visual loss include intracranial hypertension,compression of optic chiasma,and tumor invasion.A literature review was performed to summarize the cases with a tumor infiltrating the optic nerve.Most of the reported patients were adolescents and presented with anterior pituitary hormone deficiency.Enhancement of optic nerve sheaths and optic disc pallor could be identified in most of the cases.The purpose of this report is to provide awareness that in cases where a germinoma is associated with visual loss,though rare,perioptic meningeal seeding should be taken into consideration.CONCLUSION The case report suggests that children with diabetes insipidus need a complete differential diagnosis.
文摘BACKGROUND Congenital nephrogenic diabetes insipidus (CNDI) is a rare hereditary renaldisorder that is caused by mutations in AVPR2 or aquaporin 2 (AQP2). Up tonow, there are few reports about CNDI in neonates. Early clinical manifestationsof CNDI in neonates are atypical. A lack of understanding of the disease byclinicians causes frequent misdiagnoses or missed diagnoses, which may result infailure to administer treatments in time and ultimately leads to severecomplications. In this study, clinical data of a case of AVPR2 gene mutationinducedCNDI, which was confirmed by genetic testing, were retrospectivelyanalyzed to improve our understanding of this disease.CASE SUMMARY On February 1, 2020, a male neonate was hospitalized 17 d after birth due to a 7 dperiod of pyrexia. The patient’s symptoms included recurrent pyrexia,hypernatremia and hyperchloremia, which were difficult to treat. The patient wasfed on demand, and water was additionally provided between milk intakes. Acombination treatment of hydrochlorothiazide and amiloride was administered.After the treatment, body temperature and electrolyte levels returned to normal,the volume of urine was significantly reduced and the patient was subsequentlydischarged. Genetic tests confirmed that the patient carried the AVPR2 genemissense mutation c.541C>T (P.R181C), and the patient’s mother carried aheterozygous mutation at the same locus. After clinical treatment with acombination of hydrochlorothiazide and amiloride, the body temperature andelectrolyte levels returned to normal. Up until the most recent follow-up examination, normal body temperature, electrolyte levels and growth anddevelopment were observed.CONCLUSION CNDI in the neonatal period is rare, and its clinical manifestations are unspecificwith some patients merely showing recurrent fever and electrolyte disturbance.Genetic testing of AVPR2 and AQP2 can be used for screening and geneticdiagnosis of CNDI.
文摘BACKGROUND Congenital nephrogenic diabetes insipidus(CNDI)is a rare hereditary disorder.It is associated with mutations in the arginine vasopressin receptor 2(AVPR2)gene and aquaporin 2(AQP2)gene,and approximately 270 different mutation sites have been reported for AVPR2.Therefore,new mutations and new manifestations are crucial to complement the clinical deficiencies in the diagnosis of this disease.We report a case of a novel AVPR2 gene mutation locus and a new clinical manifestation.CASE SUMMARY We describe the case of a 48-d-old boy who presented with recurrent fever and diarrhea 5 d after birth.Laboratory tests showed electrolyte disturbances and low urine specific gravity,and imaging tests showed no abnormalities.Genetic testing revealed a novel X-linked recessive missense mutation,c.283(exon 2)C>T(p.P95S).This mutation results in the substitution of a proline residue with a serine residue in the AVPR2 protein sequence.The diagnosis of CNDI was confirmed based on the AVPR2 gene mutation.The treatment strategy for this patient was divided into two stages,including physical cooling supplemented with appropriate amounts of water in the early stage and oral hydrochlorothiazide(1-2 mg/kg)after a clear diagnosis.After follow-up of one and a half years,the patient gradually improved.CONCLUSION AVPR2 gene mutations in new loci and new clinical symptoms help clinicians understand this disease and shorten the diagnosis cycle.
文摘HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets) is considered to be a variant or severe form of pre-eclampsia, a life threatening complication of pregnancy. Gestational Diabetes Insipidus (GDI) can coexist with severe preeclampsia and HELLP syndrome. The combination of these two conditions presents a unique challenge to the anesthesiologist and the obstetric team, caring for this parturient. We present the case of a parturient with an unusual presentation of GDI, coexisting with severe preeclampsia and HELLP syndrome. She had two days history of polyuria and polydipsia as well as lethargy and rapidly rising serum sodium in addition to acute renal failure without any neurologic symptoms. Expeditious delivery of the baby and supportive management is essential for optimal outcomes. She underwent a repeat Cesarean section under combined spinal epidural (CSE) anesthesia. This patient was discharged on postoperative day five after clinical resolution of her signs and symptoms.

文摘To detect mutations of the aquaporin 2 gene(AQP2) and the arginine vasopressin V2 receptor gene(AVPR2) of Chinese congenital nephrogenic diabetes insipidus, and to establish the foundation for further studying the emergence mechanism of the disease and clinical diagnosis, all the exons and part of introns of AQP2 and AVPR2 genes were amplified with intronic primers, using genomic DNA extracted from three patients with congenital nephrogenic diabetes insipidus and two mothers as template, PCR product was ligated into a T-vector and then sequenced. The result was compared with the database sequence to identify the mutable sites via a BLAST search, the incidence of every mutation was analyzed, and the putative transcription factor binding sites that maybe disturbed were analyzed by MAPPER. Mutation g.1394A>G in exon 3 of AVPR2 was detected in all the subjects, g.861C>T(S167L) in exon 2 of AVPR2 and IVS1+3G>A in intron of AQP2 were detected, respectively, in two patients, and c.836A>C in 3′ untranslated region of AQP2 was detected in two patients and one mother. Four mutations were identified. g.1394A>G of AVPR2 and c.836A>C of AQP2 have high incidence in patients with nephrogenic diabetes insipidus. Detection on the two sites may become auxiliary diagnosis index of congenital nephrogenic diabetes insipidus.
文摘The coexistence of different water homeostasis abnormalities following neurosurgery represents a diagnostic and therapeutic challenge for intensive care units. This paper reports the case of a 13 year-old boy who underwent surgery for a suprasellar tumour and, immediately after surgery, developed a cerebral abscess, persistent diabetes insipidus (DI) as well as cerebral salt wasting syndrome (CSWS). The early onset of CSWS following DI has been associated with a poor prognosis and increased mortality. In cases in which these abnormalities coexist, the increased polyuria secondary to the rise in natriuresis associated with CSWS might be erroneously interpreted as a sign of poor control of the DI, thereby leading to therapeutic mistakes. Treatment basically consists of restoring electrolytes and the joint administration of desmopressin and fludrocortisone.
文摘Aim: Many cases of suprasellar region germinoma occurs in diabetes insipidus (DI), but a patient initially may come to the hospital for the chief complaint of visual impairment. The aim of this study is to determine the etiology of initial symptom presentation and the outcomes of visual impairment and DI in suprasellar region germinoma. Methods: We investigated eleven cases of single lesion suprasellar germinomas that were diagnosed and treated in our hospital. For each, a magnetic resonance imaging (MRI) was performed. Results: At the hospital visit, decreased visual acuity was found in 5/11 cases, while DI was found in all cases. The decreased visual acuity was improved in 4/5 cases by treatment, but DI improved in only 2/11 cases. In 10 cases, DI occurred earlier than visual impairment. As the initial symptom, visual impairment occurred earlier than DI in only one case and did not improve by treatment. In this case, a pituitary stalk of the normal thickness could be identified by MRI, and the optic nerve was swollen. In ten cases except this case, no significant enlargement of optic nerve was detected, and a swollen pituitary stalk was confirmed. Conclusions: In suprasellar germinomas, it is rare, but the optic nerve can significantly swell at onset, while the pituitary stalk may be intact. In such cases, visual impairment occurs earlier than DI, and visual impairment may not be improved.
文摘A 20 years old woman, admitted in our Centre at the 6th week of pregnancy, was affected by Central Diabetes Insipidus and since the age of 10 years old she assumed desmopressin at a dose of 30mg/nostril/day. She was primigravida, with normal past medical history. Fasting blood levels were normal;specific gravity of the urine: 1006;no glucosuria or proteinuria was present. Urinary and plasma osmolality were 245 and 287 mOsm/l;water intake about 2700mL/day;diuresis 2000mL/day. On the basis of the value of urine output and osmolality the dose of desmopressin was Increased at 40 mg/nostril/day. Patient was evaluated every month with fluid balance, urine volume, osmolality, and serum electrolytes. Daily dosage of desmopressin was 40mg/nostril for all the duration of pregnancy according to a trend of an adequate fluid and electrolytes balance and in absence of symptoms. Mean blood Pressure was 100/60 mmHg;coagulation, liver, renal function were normal. Fetal monitoring with periodic ultrasound detected a normal intrauterine growth. Patient had an uncomplicated labor of a healthy male baby at the 39th week. Because of an insufficient dilatation of the cervical canal caesarian section was chosen. Despite a previous Central Diabetes Insipidus may worsen in a pregnant with impaired reserve of Antidiuretic Hormone because of the changes in osmoregulatory system and increased levels of vasopressinasis in middle and late pregnancy, our patient required a slightly higher dose of desmopressin in the first trimester. Contrary to expectations the need of desmopressin did not increase during the weeks.

文摘Objective Anemia is a common public health concern in patients with type 2 diabetes worldwide.This study aimed to identify the prevalence of anemia among patients with diabetes.Methods Electronic databases,including PubMed,Scopus,Web of Sciences,and Google Scholar,were searched systematically for studies published between 2010 and 2021.After removing duplicates and inappropriate reports,the remaining manuscripts were reviewed and appraised using theNewcastleOttawa Scale(NOS)tool.A random-effects model was used to calculate the pooled estimates of the extracted data using Stata version 17.Heterogeneity of the studies was assessed using the Q statistic.Results A total of 51 articles containing information on 26,485 patients with diabetes were included in this study.The articles were mainly from Asia(58.82%)and Africa(35.29%).The overall prevalence of anemia was 35.45%(95%CI:30.30–40.76),with no evidence of heterogeneity by sex.Among the two continents with the highest number of studies,the prevalence of anemia in patients with diabetes was significantly higher in Asia[40.02;95%CI:32.72–47.54]compared to Africa[28.46;95%CI:21.90–35.50](P for heterogeneity=0.029).Moreover,there has been an increasing trend in the prevalence of anemia in patients with diabetes over time,from[15.28;95%CI:9.83–22.21]in 2012 to[40.70;95%CI:10.21–75.93]in 2022.Conclusion Globally,approximately 4 in 10 patients with diabetes suffer from anemia.Therefore,routine anemia screening and control programs every 3 months might be useful in improving the quality of life of these patients.
文摘The knowledge of the pathogenesis of type 1 diabetes mellitus(T1DM)continues to rapidly evolve.The natural course of the disease can be described in four clinical stages based on the autoimmune markers and glycemic status.Not all individuals of T1DM progress in that specific sequence.We hereby present a case of T1DM with a classical third phase(honeymoon phase)and discuss the intri-cacies of this interesting phase along with a possible future promise of“cure”with the use of immunotherapies.We now know that the course of T1DM may not be in only one direction towards further progression;rather the disease may have a waxing and waning course with even reversal of type 1 diabetes concept being discussed.The third phase popularly called the“honeymoon phase”,is of special interest as this phase is complex in its pathogenesis.The honeymoon phase of T1DM seems to provide the best window of opportunity for using targeted therapies using various immunomodulatory agents leading to the possibility of achieving the elusive“diabetes reversal”in T1DM.Identifying this phase is therefore the key,with a lot of varying criteria having been proposed.

文摘BACKGROUND Fulminant type 1 diabetes mellitus(FT1DM)that occurs during pregnancy or the perinatal period is known as pregnancy-related FT1DM(PF),always without history of abnormal glucose metabolism.Here,we present four patients who developed FT1DM during treatment but were first diagnosed with gestational diabetes mellitus(GDM).CASE SUMMARY The clinical data of four patients with GDM combined with FT1DM admitted to our hospital between July 2018 and April 2021 were collected,and the patients and their infants were followed up.All patients were diagnosed with GDM during the second trimester and were treated.The blood glucose level elevated suddenly during the third trimester and then were diagnosed with FT1DM.Two patients had an insulin allergy,and two had symptoms of upper respiratory tract infection before onset.One patient developed ketoacidosis,and three developed ketosis.Two patients had cesarean section deliveries,and two had vaginal deliveries.The growth and development of the infants were normal.C-peptide levels were lower than those at onset,suggesting progressive impairment of islet function.The frequencies of the DRB109:01,DQB103:03,DQA103:02,DPA101:03,DPA102:02,DPB105:01,DRB401:03,G 01:01,and G 01:04 human leukocyte antigen(HLA)-G alleles were high in the present study.CONCLUSION In comparison with pregnancy-associated FT1DM(PF),patients with GDM combined with FT1DM had an older age of onset,higher body mass index,slower onset,fewer prodromal symptoms,and less acidosis.The pathogenesis may be due to various factors affecting the already fragileβ-cells of GDM patients with genetically susceptible class II HLA genotypes.We speculate that GDM combined with FT1DM during pregnancy,referred to as“double diabetes,”is a subtype of PF with its own unique characteristics that should be investigated further.
文摘While chronic hyperglycaemia resulting from poorly controlled diabetes mellitus(DM)is a well-known precursor to complications such as diabetic retinopathy,neuropathy(including autonomic neuropathy),and nephropathy,a paradoxical intensification of these complications can rarely occur with aggressive glycemic management resulting in a rapid reduction of glycated haemoglobin.Although,acute onset or worsening of retinopathy and treatment induced neuropathy of diabetes are more common among these complications,rarely other problems such as albuminuria,diabetic kidney disease,Charcot’s neuroarthropathy,gastroparesis,and urinary bladder dysfunction are also encountered.The World Journal of Diabetes recently published a rare case of all these complications,occurring in a young type 1 diabetic female intensely managed during pregnancy,as a case report by Huret et al.It is essential to have a comprehensive understanding of the pathobiology,prevalence,predisposing factors,and management strategies for acute onset,or worsening of microvascular complications when rapid glycemic control is achieved,which serves to alleviate patient morbidity,enhance disease management compliance,and possibly to avoid medico-legal issues around this rare clinical problem.This editorial delves into the dynamics surrounding the acute exacerbation of microvascular complications in poorly controlled DM during rapid glycaemic control.

文摘●AIM:To identify the differential methylation sites(DMS)and their according genes associated with diabetic retinopathy(DR)development in type 1 diabetes(T1DM)children.●METHODS:This study consists of two surveys.A total of 40 T1DM children was included in the first survey.Because no participant has DR,retina thinning was used as a surrogate indicator for DR.The lowest 25%participants with the thinnest macular retinal thickness were included into the case group,and the others were controls.The DNA methylation status was assessed by the Illumina methylation 850K array BeadChip assay,and compared between the case and control groups.Four DMS with a potential role in diabetes were identified.The second survey included 27 T1DM children,among which four had DR.The methylation patterns of the four DMS identified by 850K were compared between participants with and without DR by pyrosequencing.●RESULTS:In the first survey,the 850K array revealed 751 sites significantly and differentially methylated in the case group comparing with the controls(|Δβ|>0.1 and Adj.P<0.05),and 328 of these were identified with a significance of Adj.P<0.01.Among these,319 CpG sites were hypermethylated and 432 were hypomethylated in the case group relative to the controls.Pyrosequencing revealed that the transcription elongation regulator 1 like(TCERG1L,cg07684215)gene was hypermethylated in the four T1DM children with DR(P=0.018),which was consistent with the result from the first survey.The methylation status of the other three DMS(cg26389052,cg25192647,and cg05413694)showed no difference(all P>0.05)between participants with and without DR.●CONCLUSION:The hypermethylation of the TCERG1L gene is a risk factor for DR development in Chinese children with T1DM.
文摘Obesity is a prevalent cause of diabetes mellitus(DM)and is a serious danger to human health.Type 2 DM(T2DM)mostly occurs along with obesity.Foodborne obesity-induced DM is caused by an excessive long-term diet and surplus energy.Bariatric surgery can improve the symptoms of T2DM in some obese patients.But different types of bariatric surgery may have different effects.There are some models built by researchers to discuss the surgical procedures’effects on me-tabolism in diabetes animal models and diabetes patients.It is high time to conclude all this effects and recommend procedures that can better improve metabolism.

文摘BACKGROUND Age is a significant risk factor of diabetes mellitus(DM).With the develop of population aging,the incidence of DM remains increasing.Understanding the epidemiology of DM among elderly individuals in a certain area contributes to the DM interventions for the local elderly individuals with high risk of DM.AIM To explore the prevalence of DM among elderly individuals in the Lugu community and analyze the related risk factors to provide a valid scientific basis for the health management of elderly individuals.METHODS A total of 4816 elderly people who came to the community for physical examination were retrospectively analyzed.The prevalence of DM among the elderly was calculated.The individuals were divided into a DM group and a non-DM group according to the diagnosis of DM to compare the differences in diastolic blood pressure(DBP)and systolic blood pressure(SBP),fasting blood glucose,body mass index(BMI),waist-to-hip ratio(WHR)and incidence of hypertension(HT),coronary heart disease(CHD),and chronic kidney disease(CKD).RESULTS DM was diagnosed in 32.70%of the 4816 elderly people.The BMI of the DM group(25.16±3.35)was greater than that of the non-DM group(24.61±3.78).The WHR was 0.90±0.04 in the non-DM group and 0.90±0.03 in the DM group,with no significant difference.The left SBP and SBP in the DM group were 137.9 mmHg±11.92 mmHg and 69.95 mmHg±7.75 mmHg,respectively,while they were 126.6 mmHg±12.44 mmHg and 71.15 mmHg±12.55 mmHg,respectively,in the non-DM group.These findings indicate higher SBP and lower DBP in DM patients than in those without DM.In the DM group,1274 patients were diagnosed with HT,accounting for 80.89%.Among the 3241 non-DM patients,1743(53.78%)were hypertensive and 1498(46.22%)were nonhypertensive.The DM group had more cases of HT than did the non-DM group.There were more patients with CHD or CKD in the DM group than in the non-DM group.There were more patients who drank alcohol more frequently(≥3 times)in the DM group than in the non-DM group.CONCLUSION Older adults in the Lugu community are at a greater risk of DM.In elderly individuals,DM is closely related to high BMI and HT,CHD,and CKD.Physical examinations should be actively carried out for elderly people to determine their BMI,SBP,DBP,and other signs,and sufficient attention should be given to abnormalities in the above signs before further diagnosis.

文摘BACKGROUND Among older adults,type 2 diabetes mellitus(T2DM)is widely recognized as one of the most prevalent diseases.Diabetic nephropathy(DN)is a frequent com-plication of DM,mainly characterized by renal microvascular damage.Early detection,aggressive prevention,and cure of DN are key to improving prognosis.Establishing a diagnostic and predictive model for DN is crucial in auxiliary diagnosis.AIM To investigate the factors that impact T2DM complicated with DN and utilize this information to develop a predictive model.METHODS The clinical data of 210 patients diagnosed with T2DM and admitted to the First People’s Hospital of Wenling between August 2019 and August 2022 were retrospectively analyzed.According to whether the patients had DN,they were divided into the DN group(complicated with DN)and the non-DN group(without DN).Multivariate logistic regression analysis was used to explore factors affecting DN in patients with T2DM.The data were randomly split into a training set(n=147)and a test set(n=63)in a 7:3 ratio using a random function.The training set was used to construct the nomogram,decision tree,and random forest models,and the test set was used to evaluate the prediction performance of the model by comparing the sensitivity,specificity,accuracy,recall,precision,and area under the receiver operating characteristic curve.RESULTS Among the 210 patients with T2DM,74(35.34%)had DN.The validation dataset showed that the accuracies of the nomogram,decision tree,and random forest models in predicting DN in patients with T2DM were 0.746,0.714,and 0.730,respectively.The sensitivities were 0.710,0.710,and 0.806,respectively;the specificities were 0.844,0.875,and 0.844,respectively;the area under the receiver operating characteristic curve(AUC)of the patients were 0.811,0.735,and 0.850,respectively.The Delong test results revealed that the AUC values of the decision tree model were lower than those of the random forest and nomogram models(P<0.05),whereas the difference in AUC values of the random forest and column-line graph models was not statistically significant(P>0.05).CONCLUSION Among the three prediction models,random forest performs best and can help identify patients with T2DM at high risk of DN.
文摘Pancreatic surgery units undertake several complex operations,albeit with consi-derable morbidity and mortality,as is the case for the management of complicated acute pancreatitis or chronic pancreatitis.The centralisation of pancreatic surgery services,with the development of designated large-volume centres,has contribu-ted to significantly improved outcomes.In this editorial,we discuss the complex associations between diabetes mellitus(DM)and pancreatic/periampullary disease in the context of pancreatic surgery and overall management of complex pancreatitis,highlighting the consequential needs and the indispensable role of specialist diabetes teams in support of tertiary pancreatic services.Type 3c pan-creatogenic DM,refers to DM developing in the setting of exocrine pancreatic disease,and its identification and management can be challenging,while the glycaemic control of such patients may affect their course of treatment and outcome.Adequate preoperative diabetes assessment is warranted to aid identification of patients who are likely to need commencement or escalation of glucose lowering therapy in the postoperative period.The incidence of new onset diabetes after pancreatic resection is widely variable in the literature,and depends on the type and extent of pancreatic resection,as is the case with pancreatic parenchymal loss in the context of severe pancreatitis.Early involvement of a specialist diabetes team is essential to ensure a holistic management.In the current era,large volume pancreatic surgery services commonly abide by the principles of enhanced recovery after surgery,with inclusion of provisions for optimisation of the perioperative glycaemic control,to improve outcomes.While various guidelines are available to aid perioperative management of DM,auditing and quality improvement platforms have highlighted deficiencies in the perioperative management of diabetic patients and areas of required improvement.The need for perioperative support of diabetic patients by specialist diabetes teams is uniformly underlined,a fact that becomes clearly more prominent at all different stages in the setting of pancreatic surgery and the management of complex pancreatitis.Therefore,pancreatic surgery and tertiary pancreatitis services must be designed with a provision for support from specialist diabetes teams.With the ongoing accumulation of evidence,it would be reasonable to consider the design of specific guidelines for the glycaemic management of these patients.
