Diabetes mellitus in patients with type 1 autoimmune pancreatitis at diagnosis and after corticosteroid therapy

Background:A high prevalence of diabetes mellitus(DM)coexisting with autoimmune pancreatitis(AIP)is observed.However,evidence on the circumstances under which corticosteroid therapy(CST)for AIP improves or worsens DM is scarce.This study aimed to demonstrate and identify predictors of DM control under the influence of CST.Methods:Patients diagnosed with type 1 AIP were enrolled from a prospectively maintained cohort and were classified into three groups according to the chronology in which AIP and DM were diagnosed:pre-existing DM(pDM),concurrent DM(cDM),and non-DM(nDM).The responses of DM to CST were assessed when corticosteroid was ceased or tapered to a maintenance dose and classified as‘improvement’and‘non-improvement’(including‘no change’and‘exacerbation’).Results:Among 101 patients with type 1 AIP,52(51.5%)patients were complicated with DM at the time of AIP diagnosis,with 36 patients in the cDM group and 16 patients in the pDM group.The incidences of diffuse pancreatic swelling(72.2%)and pancreatic body/tail involvement(91.7%)were significantly higher in the cDM group than in both the pDM and nDM groups.Of the 52 patients with DM,CST was administered in 48 cases.Multivariate logistic analysis identified that elevated serum gamma-glutamyl transferase(GGT)level at AIP diagnosis[odds ratio(OR)=0.032,95%confidence interval(CI):0.003-0.412,P=0.008]and pancreatic atrophy after CST(OR=0.027,95%CI:0.003-0.295,P=0.003)were negatively associated with DM control improvement.Conclusions:Patients with diffuse pancreatic swelling and pancreatic body/tail involvement in pancreatitis tended to be complicated with cDM at AIP diagnosis.CST exerted a beneficial effect on the clinical course of DM in nearly half of the AIP patients complicated with DM at diagnosis,particularly in those without elevated serum GGT levels at diagnosis and who did not experience pancreatic atrophy after CST.

Pathogenesis and treatment of diabetes mellitus-related erectile dysfunction: current therapies and potential challenges

Erectile dysfunction(ED)is one of the important complications of diabetes,which is very common in diabetic patients,affecting more than half of male patients,and the incidence of the disease is about 3.5 times that of the normal population.The pathogenesis of diabetic erectile dysfunction(DMED)is complex,involving nerve,vascular,endocrine,muscular and psychological aspects.At present,the therapeutic approaches of DMED include drug therapy,surgery,physical therapy and so on.This article provides a review of current research on the pathogenesis and treatment of DMED.Further elucidation of the pathogenesis of DMED and the development of new therapeutic approaches are of great significance for the prevention and treatment of DMED.

Tailored nutritional interventions: A precision approach to managing gestational diabetes mellitus

Gestational diabetes mellitus(GDM)is a risk to maternal-fetal health due to uncertain diagnostic criteria and treatment options.Luo's study demonstrated the efficacy of customized nutritional therapies in controlling GDM.Tailored strategies led to significant body weight loss,improved glucolipid metabolism,and fewer prenatal and newborn problems.This holistic approach,which emphasizes the notion of’chrononutrition’,takes into account optimal meal timing that is in sync with circadian rhythms,as well as enhanced sleep hygiene.Implementing tailored dietary therapy,managing meal timing,and ensuring appropriate sleep may improve results for women with GDM,opening up a possible avenue for multi-center trials.

Autologous bone marrow derived stem cell therapy in patients with type 2 diabetes mellitus-defining adequate administration methods

AIM To carry out randomized trial for evaluating effects of autologous bone marrow derived stem cell therapy(ABMSCT) through different routes.METHODS Bone marrow aspirate was taken from the iliac crest of patients. Bone marrow mononuclear cells were separatedand purified using centrifugation. These cells were then infused in a total of 21 patients comprising three groups of 7 patients each. Cells were infused into the superior pancreaticoduodenal artery(Group Ⅰ), splenic artery(Group Ⅱ) and through the peripheral intravenous route(Group Ⅲ). Another group of 7 patients acted as controls and a sham procedure was carried out on them(Group Ⅳ). The cells were labelled with the PET tracer F18-FDG to see their homing and in vivo distribution. Data for clinical outcome was expressed as mean ± SE. All other data was expressed as mean ± SD. Baseline and post treatment data was compared at the end of six months, using paired t-test. Cases and controls data were analyzed using independent t-test. A probability(P) value of < 0.05 was regarded as statistically significant. Measures of clinical outcome were taken as the change or improvement in the following parameters:(1) C-peptide assay;(2) HOMA-IR and HOMA-B;(3) reduction in Insulin dose; subjects who showed reduction of insulin requirement of more than 50% from baseline requirement were regarded as responders; and(4) reduction in HbA 1c. RESULTS All the patients, after being advised for healthy lifestyle changes, were evaluated at periodical intervals and at the end of 6 mo. The changes in body weight, body mass index, waist circumference and percentage of body fat in all groups were not significantly different at the end of this period. The results of intra-group comparison before and after ABMSCT at the end of six months duration was as follows:(1) the area under C-peptide response curve was increased at the end of 6 mo however the difference remained statistically non-significant(P values for fasting C-peptide were 0.973, 0.103, 0.263 and 0.287 respectively and the P values for stimulated C-peptide were 0.989, 0.395, 0.325 and 0.408 respectively for groups Ⅰ?to Ⅳ);(2) the Insulin sensitivity indices of HOMA IR and HOMA B also did not show any significant differences(P values for HOMA IR were 0.368, 0.223, 0.918 and 0.895 respectively and P values for HOMA B were 0.183, 0.664, 0.206 and 0.618 respectively for groups Ⅰto Ⅳ);(3) Group Ⅰshowed a significant reduction in Insulin dose requirement(P < 0.01). Group Ⅱ patients also achieved a significant reduction in Insulin dosages(P = 0.01). The Group Ⅰand Group Ⅱ patients together constituted the targeted group wherein the feeding arteries to pancreas were used for infusing stem cells. Group Ⅲ, which was the intravenous group, showed a non-significant reduction in Insulin dose requirement(P = 0.137). Group Ⅳ patients which comprised the control arm also showed a significant reduction in Insulin dosages at the end of six months(P < 0.05); and(4) there was a non-significant change in the Hb A1 c levels at the end of 6 mo across all groups(P = 0.355, P = 0.351, P = 0.999 and P = 0.408 respectively for groups Ⅰto Ⅳ). CONCLUSION Targeted route showed a significant reduction in Insulin requirement at the end of six months of study period whereas the intravenous group failed to show reduction.

Effectiveness of cognitive behavior therapy for sleep disturbance and glycemic control in persons with type 2 diabetes mellitus:A community-based randomized controlled trial in China

BACKGROUND Poor sleep quality is a common clinical feature in patients with type 2 diabetes mellitus(T2DM),and often negatively related with glycemic control.Cognitive behavioral therapy(CBT)may improve sleep quality and reduce blood sugar levels in patients with T2DM.However,it is not entirely clear whether CBT delivered by general practitioners is effective for poor sleep quality in T2DM patients in community settings.AIM To test the effect of CBT delivered by general practitioners in improving sleep quality and reducing glycemic levels in patients with T2DM in community.METHODS A cluster randomized controlled trial was conducted from September 2018 to October 2019 in communities of China.Overall 1033 persons with T2DM and poor sleep quality received CBT plus usual care or usual care.Glycosylated hemoglobin A1c(HbAlc)and sleep quality[Pittsburgh Sleep Quality Index(PSQI)]were assessed.Repeated measures analysis of variance and generalized linear mixed effects models were used to estimate the intervention effects on hemoglobin A1c and sleep quality.RESULTS The CBT group had 0.64,0.50,and 0.9 lower PSQI scores than the control group at 2 mo,6 mo,and 12 mo,respectively.The CBT group showed 0.17 and 0.43 lower HbAlc values than the control group at 6 mo and 12 mo.The intervention on meanΔHbAlc values was significant at 12 mo(t=3.68,P<0.01)and that meanΔPSQI scores were closely related toΔHbAlc values(t=7.02,P<0.01).Intentionto-treat analysis for primary and secondary outcomes showed identical results with completed samples.No adverse events were reported.CONCLUSION CBT delivered by general practitioners,as an effective and practical method,could reduce glycemic levels and improve sleep quality for patients with T2DM in community.

Manifestation of Diabetes Mellitus Type 1: A Questionnaire to Evaluate the Acceptance of Initial Intravenous Therapy

For families suddenly confronted with the diagnosis of a lifelong chronic disease, implementing a continuous iv. infusion represents restriction of movement and possibly also a psychological burden. We designed a questionnaire to evaluate the perception of pediatric patients and their parents for this treatment as part of a diabetes manifestation. Patients and their parents treated in the diabetes outpatient clinic at children’s university hospital in Mainz were asked for their opinion about “iv. infusion” and “frequency of blood taking” during their first stay in the hospital upon manifestation of diabetes. They assigned scores from 1 to 10 for the following parameters: “delivery of diagnosis”, “communication by doctor”, “execution of training”, “atmosphere during diabetes training”, “frequency of blood taking”, “iv. infusion” and “start of sc. insulin application”. Parents gave relatively high ratings. Parameters such as “frequency of blood taking” were rated with 6.1 on average. Ultimately, “frequency of blood taking”, “delivery of diagnosis” (6.11) and “iv. infusion of insulin” (6.5) scored lower than for instance “atmosphere of diabetes training” (7.95). Children awarded scores of 3.72 for “iv. infusion”, on average, whereas they scored 7.15 for the “doctor’s communication” and 7.28 for “diabetes training”. Asked if a decision in favor of a subcutaneous insulin injection right at the beginning of the therapy would have been preferable, parents were undecided. Therefore it cannot be concluded that an instant subcutaneous therapy has psychological advantages or disadvantages. The patients themselves (aged 12 - 17 years) were undecided, too, (58.3%) when asked for their preference of the subcutaneous insulin regime right at the beginning of the therapy. Nevertheless, the continuous infusion of insulin iv. was rated poorly by them. When planning further studies on this topic, the following questions should be analyzed: If the initial therapy had been started subcutaneously, would the manifestation be assessed differently by the family? Is the patients’ poor rating of the iv. insulin injection reproducible? Do other factors more greatly influence the decision for or against iv. insulin injection at the start of the therapy, such as the time needed for caretaking for the iv. injection by the nurses or possible side effects of an iv. injection? How can the start of the therapy be organized, when starting with sc. therapy, in particular regarding the first communication with patient and family?

“Diabegon”, a safe and effective polyherbal therapy for type 2 diabetes mellitus

AIM: To investigate the antihyperglycemic, antihyperlipidemic and antioxidant functions of a polyherbal formulation, "Diabegon", in human subjects with type 2 diabetes mellitus.METHODS: A total of 33 human subjects with type 2 diabetes mellitus were recruited for the study and all anthropological and biochemical parameters were recorded at the time of registration. The subjects were given hot water extract obtained from 10 gm of "Diabegon" powder, "Diabegon kwath", on an empty stomach everyday in the morning under personal supervision for 6 mo. The therapeutic functions of the "Diabegon kwath" was assessed by monitoring the blood glucoselevels at monthly intervals and glycosylated hemoglobin, lipid profile and biomarkers of oxidative stress, liver and kidney function markers at three monthly intervals in the study subjects. RESULTS: Daily administration of hot water extract of "Diabegon" regularly for 6 mo resulted in significant reductions of blood glucose and glycosylated hemoglobin levels. There was also a significant increase in high density lipoprotein cholesterol levels with concomitant decreases in total cholesterol, triglycerides, low density lipoprotein cholesterol and very low density lipoprotein. A significant improvement in glycosuria and proteinuria was also observed. Also, the subjects exhibited a significant improvement in enzymatic and nonenzymatic biochemical markers of oxidative stress. The kidney and liver functions remained normal and in fact improved in many subjects.CONCLUSION: The study which is first of its kind, advocates "Diabegon kwath" as a safe and effective Ayurvedic therapy for the treatment of human type 2 diabetes mellitus and further placebo controlled trial may substantiate the therapeutic efficacy of the formulation.

COMMENTS ON THE STUDY OF ACUPOINT COMBINATION AND REMEDIES FOR TREATMENT OF DIABETES MELLITUS WITH ACUPUNCTURE AND MOXIBUSTION

In the present paper, the author reviews the progresses in the study on acumoxi (acupuncture-moxi-bustion) treatment of diabetes mellitus (DM) from Chinese ancient classical works, Chinese and foreign journals. The therapeutic results reveal that acupuncture treatment of DM is effective in improving DM patients' symptoms via vagal-nerve reflex, regulation of neuroendocrine and immune functions. The author holds that ① correct selection of acupoints in accordance with syndrome differentiation and the related meridians and combined application of acupuncture and Chinese herbal medicines (for oral administration) are the key points for raising the therapeutic effect; and ② acupoint combination and curative methods need to be researched further.

Challenges and pitfalls of youth-onset type 2 diabetes

The incidence and prevalence of youth-onset type 2 diabetes mellitus(T2DM)are increasing.The rise in frequency and severity of childhood obesity,inclination to sedentary lifestyle,and epigenetic risks related to prenatal hyperglycemia exposure are important drivers of the youth-onset T2DM epidemic and might as well be responsible for the early onset of diabetes complications.Indeed,youth-onset T2DM has a more extreme metabolic phenotype than adult-onset T2DM,with greater insulin resistance and more rapid deterioration of beta cell function.Therefore,intermediate complications such as microalbuminuria develop in late childhood or early adulthood,while end-stage complications develop in mid-life.Due to the lack of efficacy and safety data,several drugs available for the treatment of adults with T2DM have not been approved in youth,reducing the pharmacological treatment options.In this mini review,we will try to address the present challenges and pitfalls related to youth-onset T2DM and summarize the available interventions to mitigate the risk of microvascular and macrovascular complications.

Human pluripotent stem cell-derivedβcells:Truly immature isletβcells for type 1 diabetes therapy?

A century has passed since the Nobel Prize winning discovery of insulin,which still remains the mainstay treatment for type 1 diabetes mellitus(T1DM)to this day.True to the words of its discoverer Sir Frederick Banting,“insulin is not a cure for diabetes,it is a treatment”,millions of people with T1DM are dependent on daily insulin medications for life.Clinical donor islet transplantation has proven that T1DM is curable,however due to profound shortages of donor islets,it is not a mainstream treatment option for T1DM.Human pluripotent stem cell derived insulin-secreting cells,pervasively known as stem cell-derivedβcells(SC-βcells),are a promising alternative source and have the potential to become a T1DM treatment through cell replacement therapy.Here we briefly review how isletβcells develop and mature in vivo and several types of reported SC-βcells produced using different ex vivo protocols in the last decade.Although some markers of maturation were expressed and glucose stimulated insulin secretion was shown,the SC-βcells have not been directly compared to their in vivo counterparts,generally have limited glucose response,and are not yet fully matured.Due to the presence of extra-pancreatic insulin-expressing cells,and ethical and technological issues,further clarification of the true nature of these SC-βcells is required.

Gestational diabetes mellitus: Challenges for different ethnic groups

Ethnicity is defined as"belonging to a social groupthat has a common national or cultural tradition".Membership of certain ethnic groups has long been associated with increased risk of gestational diabetes mellitus(GDM).Studies that examined ethnic differences amongst women with GDM were often conducted in western countries where women from various ethnic backgrounds were represented.The prevalence of GDM appears to be particularly high among women from South Asia and South East Asia,compared to Caucasian,African-American and Hispanic communities.For some,but not all ethnic groups,the body mass index is a risk factor for the development of GDM.Even within a particular ethnic group,those who were born in their native countries have a different risk profile for GDM compared to those born in western countries.In terms of treatment,medical nutrition therapy(MNT)plays a key role in the management of GDM and the prescription of MNT should be culturally sensitive.Limited studies have shown that women who live in an English-speaking country but predominantly speak a language other than English,have lower rates of dietary understanding compared with their English speaking counterparts,and this may affect compliance to therapy.Insulin therapy also plays an important role and there appears to be variation as to the progression of women who progress to requiring insulin among different ethnicities.As for peri-natal outcomes,women from Pacific Islander countries have higher rates of macrosomia,while women from Chinese backgrounds had lower adverse pregnancy outcomes.From a maternal outcome point of view,pregnant women from Asia with GDM have a higher incidence of abnormal glucose tolerance test results post-partum and hence a higher risk of future development of type2 diabetes mellitus.On the other hand,women from Hispanic or African-American backgrounds with GDM are more likely to develop hypertension post-partum.This review highlights the fact that management needs to be individualised and the clinician should be mindful of the impact that differences in ethnicity may have on the clinical characteristics and pregnancy outcomes inwomen affected by GDM,particularly those living in Western countries.Understanding these differences is critical in the delivery of optimal antenatal care for women from diverse ethnic backgrounds.

Non-alcoholic fatty liver disease and type 2 diabetes mellitus: The liver disease of our age?

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease that might affect up to one-third of the adult population in industrialised countries. NAFLD incorporates histologically and clinically different non-alcoholic entities; fatty liver (NAFL, steatosis hepatis) and steatohepatitis (NASH-characterised by hepatocyte ballooning and lobular inflammation &#x000b1; fibrosis) might progress to cirrhosis and rarely to hepatocellular cancer. NAFL increasingly affects children (paediatric prevalence is 4.2%-9.6%). Type 2 diabetes mellitus (T2DM), insulin resistance (IR), obesity, metabolic syndrome and NAFLD are particularly closely related. Increased hepatic lipid storage is an early abnormality in insulin resistant women with a history of gestational diabetes mellitus. The accumulation of triacylglycerols in hepatocytes is predominantly derived from the plasma nonesterified fatty acid pool supplied largely by the adipose tissue. A few NAFLD susceptibility gene variants are associated with progressive liver disease, IR, T2DM and a higher risk for hepatocellular carcinoma. Although not approved, pharmacological approaches might be considered in NASH patients.

Effects of intensive control of blood glucose and blood pressure on microvascular complications in patients with type Ⅱ diabetes mellitus

AIM: To evaluate the effects of intensive control of blood glucose and blood pressure on microvascular complications in patients with type Ⅱ diabetes by comparing the therapeutic effects of intensive and standard treatment in patients with type Ⅱ diabetes. METHODS: A total of 107 patients with type Ⅱ diabetes were randomly assigned into intensive and standard treatment groups. Patients in the intensive treatment group received preterax (perindopril/ indapamide) to control blood pressure, and gliclazide (diamicron) MR to control blood glucose. Patients in the standard treatment group received routine medications or placebo. Urinary microalbumin (UMA), urinary creatinine (UCR), the UMA/ UCR ratio, and visual acuity were monitored according to the study design of the ADVANCE trial. Direct ophthalmoscopy and seven-field stereoscopic retinal photography were used to examine the fundi at baseline,and repeated after 5 years of treatment. RESULTS: The characteristics of patients in both groups were well balanced at baseline. After 5 years of treatment, visual acuity was found to be decreased in the standard group (P=0.04), but remained stable in the intensive group. The severity of diabetic retinopathy had not progressed in patients in the intensive group, but had deteriorated in the standard group (P=0.0006). The UMA/UCR ratio was not obviously changed in patients in the intensive group, whereas it was significantly increased in the standard group (P=0.00). CONCLUSION: Intensive control of blood glucose and blood pressure can decrease the incidence or slow the progression of microvascular complications in patients with type Ⅱ diabetes, and maintain stable vision.

Management of diabolical diabetes mellitus and periodontitis nexus: Are we doing enough?

Periodontitis is the commonest oral disease affecting population worldwide. This disease is notorious for the devastation of tooth supporting structures, ensuing in the loss of dentition. The etiology for this disease is bacterial biofilm, which accumulates on the teeth as dental plaque. In addition to the biofilm microorganisms, other factors such as environmental, systemic and genetic are also responsible in progression of periodontitis. Diabetes mellitus (DM) is metabolic disorder which has an impact on the global health. DM plays a crucial role in the pathogenesis of periodontitis. Periodontitis is declared as the &#x0201c;sixth&#x0201d; major complication of DM. Evidence based literature has depicted an enhanced incidence and severity of periodontitis in subjects with DM. A &#x0201c;two way&#x0201d; relationship has been purported between periodontitis and DM. Mutual management of both conditions is necessary. Periodontal therapy (PT) may assist to diminish the progression of DM and improve glycemic control. Various advanced technological facilities may be utilized for the purpose of patient education and disease management. The present paper clarifies the etio-pathogenesis of periodontitis, establishing it as a complication of DM and elaborating the various mechanisms involved in the pathogenesis. The role of PT in amelioration of DM and application of digital communication will be discussed. Overall, it is judicious to create an increased patient cognizance of the periodontitis-DM relationship. Conjunctive efforts must be undertaken by the medical and oral health care professionals for the management of periodontitis affected DM patients.

Type 2 diabetes mellitus affects eradication rate of Helicobacter pylori

AIM: To study the eradication rate of Helicobacter pylori (Hp) in a group of type 2 diabetes and compared it with an age and sex matched non-diabetic group.METHODS: 40 diabetic patients (21 females, 19 males;56±7 years) and 40 non-diabetic dyspeptic patients (20females, 20 males; 54±9 years) were evaluated. Diabetic patients with dyspeptic complaints were referred for upper gastrointestinal endoscopies; 2 corpus and 2 antral gastric biopsy specimens were performed on each patient. Patients with positive Hp results on histopathological examination comprised the study group. Non-diabetic dyspeptic patients seen at the Gastroenterology Outpatient Clinic and with the same biopsy and treatment protocol formed the control group.A triple therapy with amoxycillin (1 g b.i.d), clarithromycin (500 mg b.i.d) and omeprazole (20 mg b.i.d.) was given to both groups for 10 days. Cure was defined as the absence of Hp infection assessed by corpus and antrum biopsies in control upper gastrointestinal endoscopies performed 6weeks after completing the antimicrobial therapy.RESULTS: The eradication rate was 50 % in the diabetic group versus 85 % in the non-diabetic control group (P＜0.001).CONCLUSION: Type 2 diabetic patients showed a significantly lower eradication rate than controls which may be due to changes in microvasculature of the stomach and to frequent antibiotic usage because of recurrent bacterial infections with the development of resistant strains.

Key details of the duodenal-jejunal bypass in type 2 diabetes mellitus rats

AIM: To investigate which surgical techniques and perioperative regimens yielded the best survival rates for diabetic rats undergoing gastric bypass. METHODS: We performed Roux-en-Y gastric bypass with reserved gastric volume, a procedure in which gastrointestinal continuity was reestablished while excluding the entire duodenum and proximal jejunal loop. We observed the procedural success rate, long-term survival, and histopathological sequelae associated with a number of technical modifications. These included: use of anatomical markers to precisely identify Treitz's ligament; careful dissection along surgical planes; careful attention to the choice of regional transection sites; reconstruction using full-thickness anastomoses; use of a minimally invasive procedure with prohemostatic pretreatment and hemorrhage control; prevention of hypo-thermic damage; reduction in the length of the procedure; and accelerated surgical recovery using fast-track surgical modalities such as perioperative permissive underfeeding and goal-directed volume therapy. RESULTS: The series of modif ications we adopted reduced operation time from 110.02 ± 12.34 min to 78.39 ± 7.26 min (P < 0.01), and the procedural success rate increased from 43.3% (13/30) to 90% (18/20) (P < 0.01), with a long-term survival of 83.3% (15/18) (P < 0.01). CONCLUSION: Using a number of fast-track and damage control surgical techniques, we have successfully established a stable model of gastric bypass in diabetic rats.

Role of ZAC1 in transient neonatal diabetes mellitus and glucose metabolism

Transient neonatal diabetes mellitus 1(TNDM1) is a rare genetic disorder representing with severe neonatal hyperglycaemia followed by remission within one and a half year and adolescent relapse with type 2 diabetes in half of the patients. Genetic defects in TNDM1 comprise uniparental isodisomy of chromosome 6, duplication of the minimal TNDM1 locus at 6q24, or relaxation of genomically imprinted ZAC1 /HYMAI. Whereas the function of HYMAI, a non-coding m RNA, is still unidentified, biochemical and molecular studies show that zinc finger protein 1 regulating apoptosis and cell cycle arrest(ZAC1) behaves as a factor with versatile transcriptional functions dependent on binding to specific GC-rich DNA motives and interconnected regulation of recruited coactivator activities. Genome-wide expression profiling enabled the isolation of a number of Zac1 target genes known to regulate different aspects of β-cell function and peripheral insulin sensitivity. Among these, upregulation of Pparγ and Tcf4 impairs insulinsecretion and β-cell proliferation. Similarly, Zac1-mediated upregulation of Socs3 may attenuate β-cell proliferation and survival by inhibition of growth factor signalling. Additionally, Zac1 directly represses Pac1 and Rasgrf1 with roles in insulin secretion and β-cell proliferation. Collectively, concerted dysregulation of these target genes could contribute to the onset and course of TNDM1. Interestingly, Zac1 overexpression in β-cells spares the effects of stimulatory G-protein signaling on insulin secretion and raises the prospect for tailored treatments in relapsed TNDM1 patients. Overall, these results suggest that progress on the molecular and cellular foundations of monogenetic forms of diabetes can advance personalized therapy in addition to deepening the understanding of insulin and glucose metabolism in general.

Glucose intolerance and diabetes mellitus in ulcerative colitis: Pathogenetic and therapeutic implications

Diabetes mellitus is one of the most frequent co-morbidities of ulcerative colitis patients.The epidemiological association of these diseases suggested a genetic sharing and has challenged gene identification.Diabetes co-morbidity in ulcerative colitis has also relevant clinical and therapeutic implications,with potential clinical impact on the follow up and outcome of patients.These diseases share specific complications,such as neuropathy,hepatic steatosis,osteoporosis and venous thrombosis.It is still unknown whether the coexistence of these diseases may increase their occurrence.Diabetes and hyperglycaemia represent relevant risk factors for postoperative complications and pouch failure in ulcerative colitis.Medical treatment of ulcerative colitis in patients with diabetes mellitus may be particularly challenging.Corticosteroids are the treatment of choice of active ulcerative colitis.Their use may be associated with the onset of glucose intolerance and diabetes,with difficult control of glucose levels andwith complications in diabetic patients.Epidemiologic and genetic evidences about diabetes co-morbidity in ulcerative colitis patients and shared complications and treatment of patients with these diseases have been discussed in the present review.
