儿童糖尿病酮症酸中毒25年回顾分析

为了解低儿童糖尿病酮症酸中毒（ＤＫＡ）的发病率,提高儿科治疗ＤＫＡ的成功率。回顾分析了２５年胰岛素依赖型糖尿病住院儿童１１４例（其中ＤＫＡ５３例）的资料。１９９０年￣１９９８年和１９７４年￣１９７９年或１９８０年￣１９８９年比较,ＤＫＡ发病率明显下降,年龄越小,ＤＫＡ发病率越高,父母文化程序低的农村儿童发病率明显高于城镇儿童,ＤＫＡ的诱因中,感染列首位（４９．１％）。停用胰岛素其次（２０．８％）。     

新诊断儿童1型糖尿病109例的临床特征

目的探讨近年新诊断儿童1型糖尿病的临床特征。方法对1999年1月1日～2005年4月30日浙江大学医学院附属儿童医院住院且为首次发病的109例1型糖尿病的临床资料进行回顾性分析,按照有无酮症酸中毒和有无低钾血症分别进行分组比较,正态分布的数据用x±s表示,采用为卡方及t检验,非正态分布的资料用中位数表示,采用Mann-WhiteyU检验进行组间比较。结果新诊断1型糖尿病儿童非酮症酸中毒(DKA)组病程明显较DKA组长,平均住院时间和糖化血红蛋白明显低于DKA组。入院时有感染诱因者21例(19.3%);伴低钾血症48例(44%),非低钾血症61例(56%);DKA组低钾血症的比率为26/47(55.3%),明显高于非DKA组的22/62(35.5%)。低钾组出现心悸、胸闷及倦怠症状出现频率为39.6%、35.4%,而非低钾组上述症状的频率分别是11.5%、16.4%,两组差异有显著性。所有患儿无1例死亡,出院后治疗依从性不一致。结论感染可能导致患儿糖尿病的进展和临床表现的出现。低钾血症组的症状较重。可能是临床症状的不典型导致了糖尿病不能及时被发现。     

儿童1型糖尿病90例

目的探讨儿童1型糖尿病(IDDM)的发病情况、临床特点、远期并发症及酮症酸中毒(DKA)的治疗。方法回顾性分析1993～2003年我院90例IDDM患儿的发病情况,临床特点,远期并发症,并探讨DKA的治疗。结果10～16岁儿童发病率最高,感染是诱发DKA的常见原因,未长期坚持胰岛素治疗易导致IDDM远期并发症的发生。结论小剂量胰岛素持续静滴、纠正水电解质紊乱、调节酸碱平衡是抢救DKA的关键;坚持长期胰岛素治疗是防治远期并发症IDDM的关键。     

儿童系统性红斑狼疮合并糖尿病4例及远期随访

目的 分析儿童系统性红斑狼疮(JSLE)合并糖尿病(DM)的临床特征并文献复习。方法 收集首都儿科研究所附属儿童医院2002至2008年收治的4例JSLE合并DM患儿的临床资料,总结其临床表现、治疗和预后。结果 4例女性患儿,3例12岁,1例8岁。4例患儿风湿免疫病相关自身抗体阳性,均确诊为JSLE;4例患儿多次查血糖升高,符合DM诊断;2/4例行胰岛素刺激试验和糖耐量试验,1例提示1型糖尿病可能性大,1例2型糖尿病可能性大;3/4例DM发病急剧,出现DM酮症酸中毒的临床表现。2例确诊为甲状腺功能减低。4例患儿均予糖皮质激素或添加免疫抑制剂治疗,狼疮活动均能缓解。1例患儿失访;3例患儿分别随访1、2和5年,其中2例长期应用胰岛素治疗,1例JSLE活动期予胰岛素治疗,病情稳定后通过控制饮食维持血糖正常;血糖均控制满意,生长发育正常。结论 DM可能JSLE的一种表现。糖皮质激素可能不是引起DM的主要原因。在治疗JSLE合并DM时,糖皮质激素是主要的治疗药物。JSLE患儿应及早预防DM的发生,除监测血糖和尿糖外,还应检测胰岛素自身抗体和谷氨酸脱羧酶抗体。

儿童时期糖尿病的危重表现及临床急救

自1999年WHO统一糖尿病的分型以来，儿童糖尿病的名称已舍弃不用。目前糖尿病临床分型为：1）1型糖尿病，主要为胰岛B细胞破坏，导致胰岛素绝对缺乏。又分为免疫介导性和特发性2个亚型，儿童青少年大部分为1型免疫介导性。     

浙江省1999～2004年新诊断儿童1型糖尿病流行病学特征及血脂水平

目的 探讨浙江省新诊断儿童1型糖尿病（DM）患儿流行病学特征及血脂特点。方法对1999年1月1日～2004年12月31日住院且为首次发病的101例1型DM患儿的年龄发病时间、出生时间、酮症酸中毒（DKA）及血脂特点进行回顾性分析。结果2004年新诊断的1型DM病人与总住院人数之比高于1999年；男童中12岁以上组病例所占同性别比例高于同年龄组女童（27．5％vs4．9％）.新诊断1型DM患儿出生于10月份至次年1月份者多于2～5月份出生者，同期发病的病例与总住院人数之比也明显升高。新诊断病例DKA组血糖和糖化血红蛋白（HbAlc）较非DKA组明显升高。两组总胆固醇（TC）和三酰甘油（TG）有显著性差异。血脂异常组与血脂正常组并DKA的比率有显著性差异，两组血糖、HbAlc和住院时间差异有显著性。结论儿童1型DM与总住院人数之比早逐年上升趋势；其发病可能与青春发育有关。初发1型DM患儿的DKA发生率又有回升。1型DM患儿TC、TG与血糖和HbAlc水平相关。     

儿童糖尿病酮症酸中毒监护与处理

儿童糖尿病酮酸中毒（ＤＫＡ）是一种发生于胰岛素依赖型糖尿病严重的代谢紊乱。其病死率约１５％。因其危及生命，患有这种病的儿童应转送至儿科监护病房。安全转送需了解此病的发病机制及并发症。     

儿童糖尿病酮症酸中毒并发脑水肿临床分析

目的探讨儿童糖尿病酮症酸中毒并发脑水肿的临床特点及危险因素。方法对糖尿病酮症酸中毒并发脑水肿患儿的临床特点及病因进行分析,并与无脑水肿的患儿资料进行对比。结果在47例糖尿病酮症酸中毒患儿中,并发脑水肿4例（8.51%）,均为重度酮症酸中毒。与未并发脑水肿同等程度的酮症酸中毒患儿相比,并发脑水肿者在治疗期间血钠上升缓慢、甚至降低,尿素氮水平较高。4例患儿中有3例应用了碳酸氢盐,用量大于未并发组。结论糖尿病患儿并发重度酮症酸中毒时易并发脑水肿。血钠上升缓慢甚或降低、血尿素氮升高及碳酸氢盐的不适当应用,可增加脑水肿发生的危险。     

The changing presentation of children with newly diagnosed type 1 diabetes mellitus

Abstract: Although it is known that the incidence of type 1 diabetes mellitus (DM) in childhood is progressively increasing, it is less clear whether the presentation of newly diagnosed DM is changing. The aim of this study was to establish whether any biochemical or clinical presentation parameters have altered over time.
A retrospective study was performed comparing newly diagnosed children with DM in two 24 month time intervals, 8 yrs apart (1988–89 and 1995–96). Fifty-seven children were diagnosed with type 1 DM in 1988–89 and 70 children in 1995–96. At presentation, children born in the later cohort had a higher pH (p < 0.001) and lower serum glucose (p < 0.05). Although the frequency of diabetic ketoacidosis (DKA) was higher in the 1988/89 cohort (63% vs. 42% in 1995/96) the absolute number of children with DKA in each time interval was similar (33 subjects in 1988–89 vs. 30 subjects in 1995/96). Islet cell antibody (ICA) levels were very different between the two cohorts; higher antibody levels were found in the 1988/89 group (p < 0.01). DKA was also associated with higher ICA titres (p < 0.05). Hospital admission stay decreased from 6.5 DS to 3.4 DS over the 8-year period (p < 0.0001).
At our institution, the presentation of children with type 1 D M is changing with many more children diagnosed before developing DKA. We speculate that a new environmental factor(s) may be responsible for the absolute increase in patients presenting without DKA, while older etiologies (both genetic and environmental) are responsible for the steady, unchanging number of patients with a more severe presentation. Greater awareness of diabetes in children is not the factor contributing to earlier diagnosis before DKA develops.     

Ketoacidosis at onset of type 1 diabetes mellitus in children--frequency and clinical presentation

Abstract: Background: Since 1987, patients with newly diagnosed diabetes mellitus type 1 under 15 yr of age have been registered in Baden‐Wuerttemberg (BW), Germany. Aim: Our aim was to describe the frequency and the clinical presentation of diabetic ketoacidosis (DKA) at onset of type 1 diabetes mellitus in children. Methods: All 31 pediatric departments in BW and one diabetes center participated in this study. Hospital records of 2121 children below 15 yr of age were examined retrospectively. DKA was defined as glucose > 250 mg/dL, pH < 7.30 or bicarbonate < 15 mmol/L and ketonuria. Statistical analysis was done after logarithmic transformation. Results: 26.3% (n = 558) of all patients presented with DKA. The mean age of these patients was 7.9 yr. The frequency of DKA is higher in girls than in boys (28.9 vs. 23.8%; p = 0.0079). Those aged 0–4 yr suffered most frequently (p < 0.0001) from ketoacidosis (36.0%). The percentage of DKA in newly diagnosed cases was constant over 10 yr. 23.3% of all patients with DKA presented with an altered level of consciousness; 10.9% of these had clinical signs of coma. No deaths occurred. The proportion of ketoacidosis does not increase concurrently with the number of diabetes manifestations in winter. Conclusion: The proportion of DKA in children with newly diagnosed diabetes mellitus is significant. In particular, children < 5 yr and girls face an increased risk. DKA may be the result of a particularly aggressive subtype of diabetes.     

25-羟维生素D与儿童1型糖尿病及酮症酸中毒的相关性研究

目的探讨血清25-羟维生素D[25-(OH)D]水平与儿童1型糖尿病(T1DM)及酮症酸中毒(DKA)的相关性。方法选取2006年1月—2009年12月期间152例住院患儿,其中52例为首次发病的T1DM患儿,包括酮症酸中毒(DKA组)21例,以及非酮症酸中毒(非DKA组)31例,其余100例为非T1DM组。检测并比较三组患儿的血清25-(OH)D水平,分析血清25-(OH)D水平与儿童T1DM及DKA的相关性。结果 DKA组患儿的血清25-(OH)D平均为(53.6±27.8)nmol/L,显著低于非DKA组的(69.7±27.9)nmol/L和非T1DM组的(81.8±28.3)nmol/L(P<0.05);非DKA组患儿的血清25-(OH)D水平显著低于非T1DM组(P<0.05)。结论 T1DM患儿的血清25-(OH)D水平低,尤以DKA患儿最为明显,维生素D在儿童T1DM发病中的潜在保护效应值得关注。     

Ketoacidosis at presentation of type 1 diabetes in children in Kuwait: frequency and clinical characteristics

Abdul‐Rasoul M, Al‐Mahdi M, Al‐Qattan H, Al‐Tarkait N, Alkhouly M, Al‐Safi R, Al‐Shawaf F, Mahmoud H. Ketoacidosis at presentation of type 1 diabetes in children in Kuwait: frequency and clinical characteristics. Background: Diabetic ketoacidosis (DKA) has significant morbidity and mortality, and is common at diagnosis in children. Objective: Describe the frequency and severity of DKA at diagnosis of type 1 diabetes mellitus (T1DM) in children in Kuwait. Methods: Hospital records of 677 diabetic children less than 12 yr of age, diagnosed during the period of 2000–2006 were reviewed. DKA was defined as blood glucose > 11 mmol/L, pH < 7.3, and/or bicarbonate < 15 mmol/L with ketonuria. Results: Of all patients diagnosed with T1DM, 255 (37.7%) presented with DKA. The frequency of DKA was constant between 2000 and 2002 (42.7–41.5%), but decreased in the following years to 30.7% in 2006 (p < 0.005). The majority had either mild or moderate DKA (74.1%). Fifty‐one (36.7%) of all children in the 0–4 yr had severe DKA compared to ten (2.9%) in the 5‐ to 8‐yr‐old group, and three (1.5%) in 9‐ to 12‐yr‐old patients (p < 0.0001). Moreover, 83% of children with severe DKA were in the 0–4 yr age group. One child (0.15%) died and twenty‐seven (4%) needed intensive care unit (ICU) care. Conclusion: Our study provides recent data on Middle Eastern population, for whom data are sparse. Although it has significantly decreased, the frequency of DKA at presentation of T1DM in children in Kuwait is still high, secondary to the high prevalence of diabetes in the community. Young children, especially those less than 2 yr old remain at high risk. Increasing the general awareness of the public as well as of pediatricians to the disease may lead to early diagnosis before the development of acidosis.     

Clinical features at the onset of childhood type 1 diabetes mellitus in Shenyang,China

Aim: To describe the clinical picture and laboratory features of Chinese children with newly diagnosed type 1 diabetes mellitus. Methods: The clinical and laboratory data of a total of 203 children who presented with newly diagnosed type 1 diabetes mellitus during a 5‐year period (2004–2008) were retrospectively analysed based on hospital records. Results: There were 88 boys (43.3%) and 115 girls (56.7%) with a median age of 8.3 years. The age distribution was categorised as 0–4 years: 52 (25.6%), 5–9 years: 57 (28.1%) and 10–14 years: 94 (46.3%). We found a peak incidence rate in the older age group. No significant seasonality was observed. The most common symptoms were polydipsia, polyuria and weight loss. Eighty‐five (41.9%) of all patients presented with diabetic ketoacidosis (DKA). The average duration of presenting symptoms before the hospital encounter was 24.5 days. Young age group children had shorter duration (17.1 days, P= 0.03) and significantly lower levels of C‐peptide (P= 0.003) and haemoglobin A1c (P= 0.049) than the other groups. Children with DKA had a higher incidence of preceding infections (P= 0.032), lower free triiodothyronine and free thyroxine levels (P= 0.035, 0.046), and higher white blood cell counts (P= 0.000) than the non‐DKA group. Conclusion: The duration between the onset of the symptoms and diagnosis was long, and the proportion of DKA in children with newly diagnosed diabetes mellitus was high. These findings call for a collaborative effort for the early recognition of symptoms by patients and physicians in order to avoid more severe types of presentation.

Predictors of glucose control in children and adolescents with type 1 diabetes mellitus

AIMS: To evaluate the glucose control [(as measured by hemoglobin A1c (HbA1c)], the factors associated with glycemic control, and possible explanations for these associations in a sample of children and adolescents with type 1 diabetes. METHODS: Data were collected on 155 children and adolescents, with type 1 diabetes mellitus, attending a multidisciplinary diabetes clinic in Portland, OR. Patients' hospital charts were reviewed to determine demographic factors, disease-related characteristics, and HbA1c level. RESULTS: Mean percent HbA1c was 9.3. Adolescents between the ages of 14 and 18 yr were in poorer metabolic control (adjusted mean percent HbA1c 0.56 higher than children 2-8 yr). Children who attended the clinic three to four times in the previous year were in better control (adjusted mean percent HbA1c 0.46 lower than those who visited two or fewer times and 1.11 lower than those who attended five or more times). Children with married parents were in better glycemic control than those of single, separated, or divorced parents (adjusted mean percent HbA1c 0.47 lower for children of married parents). This effect appeared to be mediated, in part, by the number of glucose checks performed per day. CONCLUSIONS: This study suggests that adolescents should be targeted for improved metabolic control. Diabetes team members need to be aware of changing family situations and provide extra support during stressful times. Regular clinic attendance is an important component of intensive diabetes management. Strategies must be developed to improve accessibility to the clinic and to identify patients who frequently miss appointments.     

Insulin resistance in children and adolescents with type 1 diabetes mellitus: relation to obesity

BACKGROUND: Insulin resistance is well recognized both in type 1 diabetes mellitus (T1DM) and in obesity. Studies concerning the relation between insulin resistance and overweight in T1DM have not yet been carried out. METHODS: Degree of overweight [standard deviation score-body mass index (SDS-BMI)] and daily insulin doses per weight (ID/kg), per body surface (ID/m2), and per ideal body weight (ID/IW) were recorded in 4124 children aged between 5 and 20 yr with a duration of T1DM of 4-5 yr and an adequate metabolic control [hemoglobin A1c (HbA1c) <8.0%]. SDS-BMI was compared between insulin-resistant (ID/kg > or = 1.0) and insulin-sensitive (ID/kg <1.0) children. The ID/kg, ID/m2, and ID/IW were compared between obese (SDS-BMI >1.9) and non-obese children. Multivariate linear regression analysis was conducted for the dependent variables ID/kg, ID/m2, and ID/IW, including age, gender, SDS-BMI, and HbA1c as independent variables. RESULTS: The 882 insulin-resistant children did not differ significantly (p = 0.447) with respect to SDS-BMI (median +0.38) compared to the 3242 insulin-sensitive children (median SDS-BMI +0.42). The ID/kg was significantly (p = 0.031) lower in the obese children compared to the non-obese children (median 0.80 vs. 0.83), while ID/m2 (median 31.0 vs. 26.2) and ID/IW (median 1.17 vs. 0.85) were significantly (p < 0.001) increased in the obese children. In multivariate linear regression analysis, SDS-BMI was significantly (p < 0.001) associated with an increase in ID/m2 and ID/IW and a decrease in ID/kg. CONCLUSIONS: T1DM children with insulin resistance based on ID/kg are not more overweight than insulin-sensitive children with T1DM. ID/m2 and ID/IW seem to reflect a better tool than ID/kg to describe the influence of overweight on insulin resistance in T1DM.
