Consensus Statements from the Diabetologists & Endocrinologists Alliance for the Management of People with Hypertension and Type 2 Diabetes Mellitus.

Hypertension and type 2 diabetes mellitus (T2DM) are important, intertwined public health issues. People with both conditions face significantly elevated risks of cardiovascular (CV) and renal complications. To optimize patient care, a multidisciplinary expert panel met to review recent evidence on optimal blood pressure (BP) targets, implications of albuminuria, and treatment regimens for hypertensive patients with T2DM, with the aim of providing recommendations for physicians in Hong Kong. The panel reviewed the relevant literature, obtained by searching PubMed for the publication period from January 2015 to June 2021, to address five discussion areas: (i) BP targets based on CV/renal benefits; (ii) management of isolated systolic or diastolic hypertension; (iii) roles of angiotensin II receptor blockers; (iv) implications of albuminuria for CV/renal events and treatment choices; and (v) roles and tools of screening for microalbuminuria. The panel held three virtual meetings using a modified Delphi method to address the discussion areas. After each meeting, consensus statements were derived and anonymously voted on by every panelist. A total of 17 consensus statements were formulated based on recent evidence and expert insights regarding cardioprotection and renoprotection for hypertensive patients with T2DM.

Management of Pediatric Patients Presenting with Acute Abdomen Accompanying Dilatation of the Common Bile Duct / 대한소아소화기영양학회지

PURPOSE: The aim of this study was to describe our treatment experiences with patients who had acute abdomen (AA) with common bile duct (CBD) dilatation. METHODS: The treatment outcomes in children with AA and CBD dilatation were retrospectively reviewed. According to the shape of the intrahepatic bile ducts on ultrasonography (US), the origin of the pain was estimated as choledochal cyst (CC) complication or choledocholithiasis in normal CBD. Patients with complicated CC underwent surgery, and patients with choledocholithiasis in a normal appearing CBD underwent symptomatic treatment initially. RESULTS: Of the 34 patients, 30 (88.2%) were female. The mean age of the patients was 6.4±4.9 (range, 0.8–17) years. Seventeen (50.0%) patients had CBD stones and 17 (50.0%) did not. Surgical treatment was performed in 20 (58.8%) patients, 2 of whom underwent preoperative stone removal with endoscopic retrograde cholangiopancreatography and an operation. Conservative treatment was applied in 12 (35.3%) patients (8 with and 4 without stones), 1 of whom developed symptom relapse and underwent an operation. Among the 8 patients with CBD stones, 4 (4/17, 23.5%) had complete resolution of the stones and recovery of the CBD diameter after conservative treatment. US findings of patients with stone showed a fusiform or cylindrical shape of the CBD in 14 (82.4%) patients. CONCLUSION: The presence of stones in the distal CBD and the US features of CBD dilatation may be helpful to diagnose and treat the causes of biliary dilatation. Conservative treatment can be considered as initial therapy in patients with uncomplicated CBD dilatation with stone.

Clinical Characteristics and Ultrasonographic Findings of Acute Bacterial Enterocolitis in Children / 대한소아소화기영양학회지

PURPOSE: This study clarified the bacterial pathogens currently causing acute infectious enterocolitis (AIE) in children and evaluated the clinical characteristics and ultrasonographic findings according to the different pathogens. METHODS: Medical records regarding age, sex, clinical symptoms, laboratory data, identified enteropathogens, ultrasonographic findings, treatment, and outcome of 34 patients who were diagnosed with AIE via stool examination using multiplex polymerase chain reaction (PCR) or culture, were retrospectively reviewed. RESULTS: Twenty-four patients (70.6%) were male. The mean age of the patients was 8.5±6.2 (range, 1.1–17.1) years. Six bacterial pathogens were isolated: Salmonella species (spp.) (32.4%), Campylobacter spp. (20.6%), verotoxin-producing Escherichia coli (14.7%), Staphylococcus aureus (11.8%), Clostridium difficile (8.8%), and Shigella spp. (2.9%). Abdominal pain occurred in all patients regardless of pathogen. The patients infected with Salmonella were older than those infected with verotoxin-producing E. coli (p<0.05). C-reactive protein levels were higher in patients with Salmonella and Campylobacter infections than in those with verotoxin-producing E. coli infection (p<0.05), the other clinical and laboratory data were indistinguishable between pathogens. Ultrasonography demonstrated diverse involvement of bowel segments according to pathogen. Wall thickening of both the ileum and the entire colon was the most common lesion site regardless of pathogen. CONCLUSION: Various bacterial agents cause AIE and the symptoms are diverse symptoms, however, all most children recovered spontaneously. Use of multiplex PCR on stool samples warrants improvement of its sensitivity for diagnosis of enteropathogenic bacteria. Ultrasonographic examination is useful for diagnosis of AIE; it can also detect the disease extent and severity.

Gastric Hemangioma Treated with Argon Plasma Coagulation in a Newborn Infant / 대한소아소화기영양학회지

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H₂ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

The evolution of electrocardiographic changes in patients with Duchenne muscular dystrophies / 소아과

PURPOSE: Myocardial dysfunction and dysrhythmias are inevitable consequences of Duchenne muscular dystrophy. We aimed to evaluate specific trends of electrocardiographic changes that reflect the progress of cardiomyopathy in patients with Duchenne muscular dystrophy. METHODS: Fifty electrocardiograms (ECGs) of 30 patients (ages 1 to 27 years) who had not been prescribed medications for heart failure treatment at the time of examination were retrospectively analyzed and compared with 116 ECGs of age-matched healthy 116 controls. Heart rate, leads with fragmented QRS (fQRS), corrected QT, Tpeak-to-Tend, and Tpeak-to-Tend/QT were analyzed. RESULTS: The patients with Duchenne muscular dystrophy failed to show a normal age-related decline in heart rate but showed an increasing trend in the prevalence of fQRS, corrected QT, corrected Tpeak-to-Tend, and Tpeak-to-Tend/QT over time. In the ≤10-year-old patient group, a significant difference was found only in the prevalence of fQRS between the patients and the controls. The prevalence of fQRS, heart rate, Tpeak-to-Tend/QT, and corrected Tpeak-to-Tend demonstrated significant differences between the patients and the controls in the middle age group (11 to 15 years old). All the indexes were statistically significantly different in the ≥16-year-old patient group. CONCLUSION: The prevalence of lead with fQRS representing regional wall motion abnormalities was higher in the young patients than in the young healthy controls, and this might be one of the first signs of myocardial change in the patients. Markers of depolarization and repolarization abnormalities were gradually prominent in the patients aged >10 years. Further studies are needed to confirm these findings.

Clinical Features and Extraintestinal Manifestations of Crohn Disease in Children / 대한소아소화기영양학회지

PURPOSE: The aim of this study was to investigate the clinical features and extraintestinal manifestations (EIMs) of Crohn disease (CD) in Korean pediatric patients. METHODS: The medical records of 73 children diagnosed with CD were retrospectively reviewed. Data regarding baseline demographic and clinical characteristics, including CD phenotype at diagnosis based on the Montreal classification, and clinical features and course of EIMs were investigated. RESULTS: Fifty-two (71.2%) of the patients were males. The mean age of the patients was 12.5 years. The mean follow-up period was 3.4 years. The disease location was ileal in 3 (4.1%) of the patients, colonic in 13 (17.8%), ileocolonic in 56 (76.7%). The clinical behavior was inflammatory in 62 (84.9%) of the patients, stricturing in 8 (11.0%), and penetrating in 3 (4.1%). Perianal abscesses or fistulas were found in 37 (50.7%) of the patients. EIMs observed during the study period were anal skin tag in 25 patients (34.2%), hypertransaminasemia in 20 (27.4%), peripheral arthritis in 2 (2.7%), erythema nodosum in 2 (2.7%), vulvitis in 1 (1.4%), uveitis in 1 (1.4%), and pulmonary thromboembolism in 1 (1.4%). CONCLUSION: Perianal diseases and manifestations were present in more than half of Korean pediatric CD patients at diagnosis. Inspection of the anus should be mandatory in Korean children with suspicious CD, as perianal fistulas, abscesses, and anal skin tags may be the first clue to the diagnosis of CD.

Vitamin D deficiency in children aged 6 to 12 years: single center's experience in Busan

PURPOSE: This study investigated the prevalence and risk factors associated with vitamin D deficiency in children. METHODS: We analyzed the medical records of 330 patients from the age of 6 to 12, who visited the endocrinology clinic of the Department of Pediatrics at Pusan National University Hospital, from September, 2013 to May, 2014. According to their serum 25-hydroxyvitamin D (25(OH)D) levels, the patients were grouped into either the deficiency group (25(OH)D<20 ng/mL), or the sufficiency group (25(OH)D≥20 ng/mL). The differences between the 2 groups were compared. RESULTS: There were 195 patients (59.1%) who had vitamin D deficiency. Their mean serum 25(OH)D level was 14.86±3.20 ng/mL. The differences in sex, age, and pubertal status between the 2 groups were not statistically significant. Weight standard deviation score (SDS), and body mass index SDS, were significantly higher in the vitamin D deficiency group (P=0.002 for each), compared to the sufficiency group. Compared with Autumn, both Spring (odds ratio [OR], 9.7; 95% confidence interval [CI], 4.3–22.0), and Winter (OR, 5.9; 95% CI, 3.5–10.0), were risk factors for vitamin D deficiency. In multiple logistic regression analysis, only seasonal differences have been confirmed to have an effect on vitamin D deficiency. CONCLUSION: Vitamin D deficiency in children aged 6 to 12 years is very common. Spring and Winter are the most important risk factors for vitamin D deficiency. We suggest that it is necessary to supplement the guideline for the vitamin D intake according to our situation.

Living Related Liver Transplantation in an Infant with Neonatal Hemochromatosis / 대한소아소화기영양학회지

Neonatal hemochromatosis (NH) is a severe neonatal liver injury that is confirmed by extra-hepatic iron accumulation. Although a recent study described treating NH with exchange transfusions and intravenous immunoglobulin, liver transplantation should be considered for patients with severe liver failure that does not respond to other medical treatment. Herein, we report the case of a two-month-old female infant who presented with persistent ascites and hyperbilirubinemia. Her laboratory findings demonstrated severe coagulopathy, high indirect and direct bilirubin levels, and high ferritin levels. Abdominal magnetic resonance imaging presented low signal intensity in the liver on T2-weighted images, suggesting iron deposition. The infant was diagnosed with NH as a result of the clinical findings and after congenital infection and metabolic diseases were excluded. The infant was successfully treated with a living-donor liver transplantation. Living related liver transplantation should be considered as a treatment option for NH in infants.

Clinical significance of serum alanine aminotransferase and lifestyle intervention in children with nonalcoholic fatty liver disease / 소아과

PURPOSE: This study aimed to investigate the clinical significance of serum alanine aminotransferase (ALT) levels in children with nonalcoholic fatty liver disease (NAFLD) and the effect of lifestyle intervention on NAFLD. METHODS: The clinical data of 86 children diagnosed with NAFLD were reviewed retrospectively. Forty-six patients belonged to the elevated ALT group and 40 to the normal ALT group. The clinical parameters of patients with NAFLD were also compared based on the status of ALT levels after lifestyle intervention. RESULTS: Patients with elevated ALT had significantly higher body mass index (BMI) scores than those with normal ALT (P<0.05). Of all the patients with elevated ALT, 89% exhibited moderate or severe degree of fatty change in the liver on ultrasonographic examination, whereas most patients with normal ALT exhibited mild or moderate degree changes. Liver biopsy was performed in 15 children with elevated ALT and all showed mild histological changes. Of all patients with elevated ALT, 49% achieved normal ALT levels after lifestyle intervention. Those with more severe histological changes tended to have continuously increasing ALT levels. There was no correlation between the normalization of posttreatment ALT level and BMI, as well as ultrasonographic findings at diagnosis. CONCLUSION: ALT elevation in NAFLD is highly associated with higher BMI scores and more severe degree of fatty changes on ultrasonographic examination. Lifestyle intervention can significantly improve ALT in children with NAFLD. The degree of histologic changes appears to be a predictor of the treatment response to NAFLD.

Prevalence and Risk Factors for the Weight Loss during Hospitalization in Children: A Single Korean Children’s Hospital Experience / 대한소아소화기영양학회지

PURPOSE: Undernutrition during hospitalization increases the risk of nosocomial infection and lengthens the disease courses. The aim of this study was to evaluate the risk factors of weight loss during hospitalization in children. METHODS: All the patients who were admitted in general wards between April and May 2014 were enrolled. Patients aged >18 years and discharged within 2 days were excluded. Weight loss during hospitalization was defined as a decrease in body weight of >2% in 8 hospital days or on the day of discharge. Patients who lost body weight during hospitalization were compared with patients who maintained their body weights. Significant parameters were evaluated by using the multivariate logistic regression analysis. RESULTS: We enrolled 602 patients, of whom 149 (24.8%) lost >2% of their body weight. Complaint of pain (p=0.004), admission to the surgical department (p=0.001), undergoing surgery (p=0.044), undergoing abdominal surgery (p=0.034), and nil per os (NPO) durations (p=0.003) were related to weight loss during hospitalization. The patients who had high weight-for-age tended to lose more body weight (p=0.001). Admission to the surgical department (odds ratio [OR], 1.668; 95% confidence interval [CI], 1.054-2.637; p=0.029) and long NPO durations (OR, 1.496; 95% CI, 1.102-2.031; p=0.010) were independent risk factors of weight loss during hospitalization. The patients with high weight-for-age tended to lose more weight during hospitalization (OR, 1.188; 95% CI, 1.029-1.371; p=0.019). CONCLUSION: Greater care in terms of nutrition should be taken for patients who are admitted in the surgical department and have prolonged duration of nothing by mouth.

Familial young-onset diabetes, pre-diabetes and cardiovascular disease are associated with genetic variants of DACH1 in Chinese.

In Asia, young-onset type 2 diabetes (YOD) is characterized by obesity and increased risk for cardiovascular disease (CVD). In a genome-wide association study (GWAS) of 99 Chinese obese subjects with familial YOD diagnosed before 40-year-old and 101 controls, the T allele of rs1408888 in intron 1 of DACH1(Dachshund homolog 1) was associated with an odds ratio (OR) of 2.49(95% confidence intervals:1.57-3.96, P = 8.4 × 10(-5)). Amongst these subjects, we found reduced expression of DACH1 in peripheral blood mononuclear cells (PBMC) from 63 cases compared to 65 controls (P = 0.02). In a random cohort of 1468 cases and 1485 controls, amongst top 19 SNPs from GWAS, rs1408888 was associated with type 2 diabetes with a global P value of 0.0176 and confirmation in a multiethnic Asian case-control cohort (7370/7802) with an OR of 1.07(1.02-1.12, P(meta)  = 0.012). In 599 Chinese non-diabetic subjects, rs1408888 was linearly associated with systolic blood pressure and insulin resistance. In a case-control cohort (n = 953/953), rs1408888 was associated with an OR of 1.54(1.07-2.22, P = 0.019) for CVD in type 2 diabetes. In an autopsy series of 173 non-diabetic cases, TT genotype of rs1408888 was associated with an OR of 3.31(1.19-9.19, P = 0.0214) and 3.27(1.25-11.07, P = 0.0184) for coronary heart disease (CHD) and coronary arteriosclerosis. Bioinformatics analysis revealed that rs1408888 lies within regulatory elements of DACH1 implicated in islet development and insulin secretion. The T allele of rs1408888 of DACH1 was associated with YOD, prediabetes and CVD in Chinese.

The reproductive and metabolic effect of rosiglitazone on Chinese women with polycystic ovarian syndrome--a double-blind randomized placebo-controlled study.

OBJECTIVE: To investigate whether an insulin sensitizer has any effect on amenorrhea and clinical and biochemical hyperandrogenism in Chinese women with polycystic ovarian syndrome (PCOS). DESIGN: Randomized controlled double-blind trial. SETTING: A tertiary referral center, Hong Kong. PATIENT(S): Chinese women who fulfilled the Rotterdam criteria of PCOS (n = 70). INTERVENTION(S): Rosiglitazone 4 mg daily for the first month followed by 4 mg twice daily for 11 months. MAIN OUTCOME MEASURE(S): Menstrual status as well as clinical and biochemical hyperandrogenism. RESULT(S): There is a significantly higher rate of regular menses among the treatment arm (16 [50.0%] of 32 vs 4 [11.8%] of 34) at 6 months and the improvement appeared to be sustained (10 [41.7%] of 24 vs 6 [20.0%] of 30) at 12 months. There was no change in the acne and hirsutism scores as well as serum T levels in both arms. CONCLUSION(S): We found a possible benefit in menstrual cyclicity but a lack of improvement in hyperandrogenism in our Chinese population. CLINICAL TRIAL REGISTRATION NUMBER: ChiCTR-TRC-09000670 (Chinese Clinical Trial Registry).

A Rare Case of Scimitar Syndrome Accompanied with an Imperforate Anus in a Newborn

Scimitar syndrome (SS) is a rare congenital anomaly characterized by hypoplasia of the right lung and partially anomalous pulmonary venous drainage to the inferior vena cava. The term scimitar derives from the shadow created by the anomalous pulmonary vein on chest X-ray that closely resembles that of a curved Turkish sword. It rarely presents as an isolated abnormality. Various cardiac and non-cardiac anomalies have been association with SS, such as right lung hypoplasia, dextroposition of the heart, hypoplasia of the right pulmonary artery, systemic arterial blood supply to the right lower lung from the infra-diaphragmatic aorta, and a secundum type of atrial septal defect. However, an imperforate anus has not been reported previously in association with SS. We describe the first case of infantile scimitar syndrome accompanied with an imperforate anus in a newborn who presented with tachypnea and right pulmonary atelectasis.

A case of reactive arthritis after Salmonella enteritis in in a 12-year-old boy / 소아과

Reactive arthritis comprises a subgroup within infection-associated arthritides in genetically susceptible hosts. Researchers and clinicians recognize two clinical forms of reactive arthritis which occurs after genitourinary tract infection and after gastrointestinal tract infection. Chlamydia infection has been implicated as the most common agent associated with post-venereal reactive arthritis. Studies have proposed Shigella infection, Salmonella infection, or Yersinia infection as the microorganisms responsible for the post-dysenteric form. The human leukocyte antigen (HLA)-B27 antigen is the best-known predisposing factor. We report a case of HLA-B27-associated reactive arthritis after Salmonella enteritis at Pusan National University hospital.

Accuracy of an Interferon-gamma Release Assay to Detect Active Tuberculosis in Children: A Pilot Study / 소아감염

PURPOSE: Early diagnosis of active tuberculosis (TB) in children is difficult. The widely used tuberculin skin test has low sensitivity and cross reactivity with non-tuberculous mycobacteria or Bacille Calmette-Guerin vaccination. Interferon gamma release assays have been shown good diagnostic accuracy for active in adults. But studies in children were limited. The purpose of this study was to examine the performance of enzyme-linked immunospot assay (ELISpot) as an initial test in the diagnosis of active tuberculosis in children. METHODS: In a hospital-based study, we prospectively examined the performance of ELISPot in 33 children suspected of active TB. TB was confirmed bacteriologically or histologically. RESULTS: Among 33 patients, 9 had active tuberculosis. When tested, they all had a positive test result from the ELISpot. The sensitivity and specificity of the assay were 100% (95% CI, 66.4-100%) and 95.8% (95% CI, 78.9-99.9%) respectively. CONCLUSION: ELISpot might be an useful and improved clinical diagnostic method for the detection of active TB in children.

Analysis of neonatal sepsis in one neonatal intensive care unit for 6 years / 소아과

PURPOSE: Sepsis is a significant cause of morbidity and mortality in the newborn, particularly in preterm. The objective of this study was to analyze the incidence rate, causative pathogens and clinical features of neonatal sepsis in one neonatal intensive care unit (NICU) for 6 years. METHODS: This study was retrospectively performed to review the clinical and laboratory characteristics including sex, gestational age, birth weight, Apgar score, length of hospitalization, length of total parenteral nutrition, presence of central venous catheter, underlying diseases, laboratory findings, microorganisms isolated from blood culture, complications and mortality in 175 patients between January 2003 and December 2008. RESULTS: 1) Sepsis was present in 175 of 3,747 infants for 6 years. There were more gram-positive organisms. 2) The gram-negatives were more prevalent in preterm. There were no significant differences of other clinical features between two groups. 3) Underlying diseases were found in 73.7%, and the most common disease was cardiovascular disease. The most common organisms of gram-positives and gram-negatives were methicillin resistant Staphylococcus aureus (MRSA) and Serratia marcescens. 4) There was statistically significant difference on platelet counts between two groups (P<0.05). 5) Complications were found in 18.3% and septic shock was the most common. MRSA was the most common pathogen in sepsis with complication. 6) The mortality rate was 7.4%. 7) There were differences in monthly blood stream infection/1,000 patient-days. CONCLUSION: The studies about the factors that can influence neonatal sepsis will contribute to decrease the infection rates in NICUs.

Effects of systolic and diastolic blood pressures on incident coronary heart disease and all-cause death in Chinese women with Type 2 diabetes: the Hong Kong Diabetes Registry.

BACKGROUND: Elevated blood pressure (BP) is an important risk factor for the development of coronary heart disease (CHD), although the threshold above which the risk increases has not been clearly defined. The aim of the present study was to examine the full-range association between BP and CHD. METHODS: A prospective cohort of 3861 Chinese women with Type 2 diabetes mellitus (T2DM) was followed for a median of 5.61 years. Restricted cubic spline analysis was used to examine the relationship between BP and CHD. RESULTS: Subjects who developed CHD were older, more likely to be smokers, had a significantly longer duration of diabetes, higher systolic BP (SBP), glycated hemoglobin, albuminuria, low-density lipoprotein-cholesterol, and triglycerides, and lower estimated glomerular filtration rate and high-density lipoprotein-cholesterol. Mortality was higher in those who developed CHD compared with those who did not, with all-cause death in 30.2% and 7.8% of patients, respectively. Over 21,641 and 22 049 person-years follow up, 4.4% of patients (n = 169) developed CHD and 8.8% (n = 340) died, respectively. The relative risk of SBP for CHD was constant up to 120 mmHg, after which it started to rise: from 130 mmHg, each 10-mmHg increase in SBP was associated with a 1.13-fold increased risk of CHD. CONCLUSIONS: We identified 130 mmHg as the threshold of SBP for increased risk of CHD in Chinese female patients with T2DM. It appears that 67-77 mmHg is the optimal range for diastolic BP, within which the risk of CHD is lowest.

Glucose intolerance and cardiometabolic risk in children exposed to maternal gestational diabetes mellitus in utero.

OBJECTIVE: The goal was to examine the carbohydrate tolerance and cardiometabolic risk among children exposed to maternal gestational diabetes mellitus in utero. METHODS: In this study, 164 Chinese children whose mothers had participated in a previous study on the screening and diagnosis of gestational diabetes mellitus (63 had gestational diabetes mellitus and 101 had normal glucose tolerance during the index pregnancies) underwent follow-up evaluations at a median age of 8 years (range: 7-10 years). Children's weight, height, hip and waist circumferences, and blood pressure were measured, and weight-adjusted oral glucose tolerance tests were performed. RESULTS: Six children (3.7%) demonstrated impaired glucose regulation or diabetes mellitus at the follow-up evaluation. Children exposed to maternal gestational diabetes mellitus had significantly higher systolic (94+/-1.2 vs 88+/-0.9 mmHg) and diastolic (62+/-0.8 vs 57+/-0.6 mmHg) blood pressure values and lower high-density lipoprotein cholesterol (1.58+/-0.04 vs 1.71+/-0.03 mmol/L) levels, after adjustment for age and gender. A high (>or=90th percentile) umbilical cord insulin level at birth was associated with abnormal glucose tolerance in the offspring. CONCLUSIONS: Maternal gestational diabetes mellitus increases the offspring's cardiometabolic risk, and in utero hyperinsulinemia is an independent predictor of abnormal glucose tolerance in childhood.

Erectile dysfunction predicts coronary heart disease in type 2 diabetes.

OBJECTIVES: We examined the predictive power of erectile dysfunction (ED) on coronary heart disease (CHD) events in Chinese men with type 2 diabetes. BACKGROUND: Subjects with diabetes are prone to develop cardiovascular complications. Erectile dysfunction is strongly associated with CHD in cross-sectional studies, but prospective data are lacking. METHODS: A consecutive cohort of men with no clinical evidence of cardiovascular disease underwent comprehensive assessments for diabetic complications. Erectile dysfunction was defined according to the definition of the National Institutes of Health Consensus Conference 1992. Coronary heart disease events were censored with centralized territory-wide hospital databases in 2005. RESULTS: Of 2,306 subjects (age: 54.2 +/- 12.7 years; follow-up: 4.0 [range 1.7 to 7.1] years), 26.7% had ED at baseline. The incidence of CHD events was higher in men with ED than those without (19.7/1,000 person-years, 95% confidence interval [CI] 14.3 to 25.2 person-years vs. 9.5/1,000 person-years, 95% CI 7.4 to 11.7 person-years). Men who developed CHD events were older; had a higher frequency of ED and microvascular complications; had longer duration of diabetes; and had higher blood pressure, total cholesterol, low-density lipoprotein cholesterol, and urinary albumin/creatinine ratio but lower high-density lipoprotein cholesterol and estimated glomerular filtration rate than those without CHD events. Erectile dysfunction remained an independent predictor for CHD events (hazard ratio 1.58, 95% CI 1.08 to 2.30, p = 0.018) after adjustment for other covariates along with age, duration of disease, and use of antihypertensive agents and albuminuria. CONCLUSIONS: In type 2 diabetic men without clinically overt cardiovascular disease, the presence of ED predicts a new onset of CHD events. Symptoms of ED should be independently sought to identify high-risk subjects for comprehensive cardiovascular assessments.
