[Possibilities of applying basis/bolus method in treatment of adolescent with type 1 diabetes mellitus]


MARCH 22, 2012

Lege Artis Medicinae - 2012;22(03)

[INTRODUCTION - Since the end of the pastcentury, the basis/bolus method has been adeterminate factor of adjusting insulin thera-py. Experiences with insulin pump treatmentprove that well-quantified and adequatelytimed basal insulin treatment can fully com-pensate for the diurnal glucose-producingactivities of the liver and the diurnal changesin the activity of insulin receptors. Suitablyselected basal insulin treatment can, there-fore, keep the changes in blood sugar levelthat are dependent of the diet’s carbohydratecontent well under control. CASE REPORT - By presenting the approxi-mately five-year treatment of an adolescentboy, the author presents the current options(and failures) of insulin therapy that might beused with more or less success. Each treat-ment approach had its place in the variousstages of the patient’s diabetes. Nevertheless,insulin pump therapy, admittedly the moststate-of-the-art method today was unsuccess-ful due to patient’s lack of compliance, thusthis treatment had to be stopped. Still, on thebasis of the experiences with insulin pumptherapy, the restored intensive-conservativetreatment was set up on glargine basalinsulin, defining doses of bolus in correlationwith 10 grams of carbohydrate, which madethe diet less strict. This approach resulted ina considerable improvement of the patient’smetabolic profile. CONCLUSION - The right choice of thedoses and efficacy curve of basal insulin isessential for achieving a good metabolic bal-ance during intensive-conservative therapy.In case of deteriorating metabolic balance,suspending the inefficient insulin pump ther-apy is justified and means no disadvantagefor the patient, as long as the subsequentadjustment is prudent. By defining doses of ashort-acting bolus insulin analogue in corre-lation with carbohydrate intake along withglargine therapy permits adaptation to themetabolism of patients with poor compli-ance and unsatisfactory lifestyle - in expec-tation of better results. ]

[Epidemiological surveillance systems used by international organisations in military crisis management operations]

KOPCSÓ István, KISS Antal Zsolt

[Facing new challenges and growing requirements, the renewal and adjustment of doctrines, methods and technology is an indispensable progressive need for modern militaries. In order to achieve the maximal protection of troops and conservation of fighting strength, innovation is continuous and has greatly accelerated in the whole spectrum of Force Health Protection. Owing to the development of technology, portable capabilities that had been available only in the hinterland have become available in the military medical support area. Utilising mobile information technology solutions, the continuous, real-time information flow between the tactical level medical units and the higher level medical analysts and decision makers has become technically feasible, which results in a significant widening of epidemiological surveillance capabilities as well. We discuss the current challenges of expeditionary- type military operations and their general epidemiological aspects and the morbidity reporting and monitoring systems used in international military missions. Furthermore, we overview the milestones of the development of the NATO near-real-time epidemiological surveillance system, the NATO Deployment Health Surveillance Capability, which functions as a branch of the Budapestbased multinational NATO Centre of Excellence for Military Medicine.]

[What is the doctor like, if female? - Female doctors’ ideal image based on empirical studies]

MOLNÁR Regina, GIRASEK Edmond, CSINÁDY Adriána, BUGÁN Antal

[The aim of our study was to examine thestereotypes about female doctors and howdo the female medical students perceivethe working female doctors whom are theirrole models. In the first study (247 from theAlbert Szent-Györgyi Medical and Pharma-ceutical Centre at the University of Szegedand 256 from the Medical and HealthScience Centre of the University ofDebrecen) the female medical students’professional socialization was compared tothe male counterparts’. In the second study(from University of Szeged, 214 femalemedical students, 132 female jurist stu-dents) female medical and jurist students'professional socialization was comparedincluding the comparison of stereotypes inconnection with working female doctorsand jurists. Female medical students’ professionalsocialization is different that of male coun-terparts in several aspects: being morealtruistic, more family centered, gettingcommited to the profession earlier, havingmore ambiguous carrier planes, and asmaller percentage of their parents’ has adegree or is a medical doctor, then for malemedical students. The female medical doc-tor has positive, idealistic, altruistic charac-ters according to both female studentgroups’ opinions. The female doctor’simage is more often associated with char-actersitics implying problems by femalemedical students then jurists. The unfold-ing image of these stereotypes is a femaledoctor who is willing to help, however,faceing lots of hardnesses during work.If the female medical students’ image of theproblematic life of these idealistic femaledoctors’ is known, it provides an opportu-nity to prepare them for the hardnessesthey’ll face avoiding role conflicts andhealth problems in the future.]

[The new British recommendations for the treatment of lower back pain on the basis of the new NICE guidelines - comparison with the Hungarian therapeutic practice]


[The new NICE guidelines on lower back pain emphasise the importance of clinical assessment. Radiological imaging methods are used primarily to exclude severe diseases, such as tumour, infection, trauma or inflammation. It’s crucial to inform patients and encourage them to use self-management and stay active. Pain management is guided by the analgesic ladder. A complex physical and psychological treatment is used, which involves a structured exercise programme, manual therapy and acupuncture, taking into account the preferences of the patient. Depending on the aetiology, surgical intervention should be considered in therapy-resistant cases. Finally, the authors compare the above guidelines with the Hungarian practice in this field.]

[Disturbances of the bone metabolism in type 1 diabetic patients]


[AIMS - Because of contradictory data in literature our aim was to study bone metabolic disturbances and their correlates with anthropometric and metabolic parameters in type 1 diabetic patients (T1DM). Since quantitative bone ultrasound (QUS) measures bone qualities different from BMD, and it has only been scarcely investigated in T1DM, our aim was to describe covariates of QUS parameters. PATIENTS AND METHODS - Osteodensitometry was performed (lumbal spine, femur neck - DEXA; calcaneal ultrasound) on 115 T1DM patients (34 male, 81 female; mean age: 41.4±11 [± SD] yrs; BMI: 23.9±3.0 kg/m2; diabetes duration: 21.6±11.7 yrs; HbA1c: 8.1±1.3%). In addition anthropometric, blood pressure and laboratory parameters (HbA1c, lipids, renal function, fibrinogen, homocystein, PTH, TSH, β-CrossLaps, vitamine D3, osteocalcin, osteoprotegerin) were measured, data using a questionnaire were collected. RESULTS - The prevalence of osteoporosis was 9/112 (8%). A further 21/62 patients with osteopenia were found. Disturbances of bone metabolism have been more frequently proven on lumbal spine (p<0.001). Using multiple linear regression modelling, the independent covariates of osteopathy were systolic blood pressure, body weight, β-CrossLaps and cystatin C. The average broadband ultrasound attenuation (BUA) was 114.2±14.9 in males vs. 108.4±16.3 dB/MHz in females (p=0.07), the mean speed of sound (SOS) 1552±26 in males vs. 1559±32 m/s in females (p=0.32). SOS values in addition to bone density were associated with fracture risk. The independent covariates of BUA were body weight and height (R=0.473, p<0.001), and of SOS only fibrinogen (R=0.305, p=0.032). CONCLUSIONS - According to our results the prevalence of osteoporosis in acceptable controlled T1DM patients is relatively low. The more common metabolic calcipenic osteopathy show a correlation with body weight, markers of bone resorption and diabetic complications/co-morbidities (nephropathy, hypertension) being therefore not only an a priori consequence but also a complication of diabetes mellitus. Our data provide baseline data of QUS in type 1 diabetic patients. Because of the frequency of lower bone mineral content and their known high fracture risk bone metabolism screening of T1DM patients has to be considered.]

[Measurement of coronary artery calcification in adults with type 1 diabetes mellitus using dual-source, multi-slice computed tomography]


[INTRODUCTION - Coronary artery calcification can be characterized non-invasively and numerically using computed tomography (CT). In adult patients with type 1 diabetes mellitus, coronary atherosclerosis may be present without clinical symptoms. PATIENTS AND METHODS - Asymptomatic adults with type 1 diabetes mellitus (n=46) were investigated. Coronary artery calcification was expressed in Agatston-scores using a dual source CT scanner. RESULTS - Twenty-one patients had a coronary artery calcification score of ≥1 (range 1-2353), while in 25 patients no detectable calcium (score 0) was observed. Patients with vs. without coronary artery calcification had a higher age (51.0±9.9 vs. 42.8±7.8 years; p=0.0045), a longer duration of diabetes (30.6±9.2 vs. 24.2± 8.6 years; p=0.0238), a higher waist circumference (87.9±11.5 vs. 79.7±9.4 cm; p=0.0146), and a higher BMI (26.2±2.9 vs. 23.8±3.1 kg/m2;p=0.0109). Moreover, patients with vs. without detectable coronary artery calcification had higher serum lipid levels (LDL-cholesterol, 3.35±0.32 vs. 3.01±0.68 mmol/l; p=0.0069) and higher serum uric acid levels (228.4±48.7 vs. 195.1±39.4 µmol/l; p=0.0437). Hypertension was more common (p=0.0144) in patients with coronary artery calcification than in patients without it. There was no significant difference between the groups in HbA1c (7.97±0.85 vs. 8.26±1.28%; p=0.7491), however, estimated insulin sensitivity was lower in patients with vs. without detectable coronary artery calcification (7.15±2.09 vs. 9.20±2.03 mg/kg/min; p=0.0017). CONCLUSION - Our results suggest that coronary artery disease in type 1 diabetic patients is associated with higher age, longer duration of diabetes, and cardiovascular risk factors rather than with long-term glucose control.]

[Optimalisation of basal insulin regimen for adolescent patients with type 1 diabetes]


[INTRODUCTION - During the total phase of type 1 (insulin-dependent) diabetes mellitus (T1DM), both the quantity and the quality of daily insulin doses must be determined to help the daily blood-glucose profile approach normoglycaemia, derived from the patient’s diet and regimen. Adolescence for young people with T1DM is a rather stressful - often shocking - psychosomatic state, due not only to the increased - but erratic - secretion of contrainsular hormones (predominantly growth hormone), but also to the special mental state of the child. Accordingly, choosing the right kind and amount of basal insulin to compensate the contrainsular effect is crucial for optimal treatment during this stage of life as well. CASE REPORT - We describe the process of optimising metabolic balance and basal insulin demand in a 11-year-old, adolescent girl with T1DM for 7.5 years using glargine insulin. In order to achieve this goal, both the dosage of glargine and the daily schedule of its administration needed to be modified. CONCLUSIONS - To achieve optimal metabolic results, both the quantity and the efficacy curve of basal insulin must and can be adapted to the actual stage of general somatic development. The demand for basal insulin during puberty may be well beyond the widely approved limit of 50%. Adapting the administration of glargine insulin to a daily schedule has the potential to counterbalance increasing contrainsular effects.]

[The number of diabetic patients will be doubled in the coming decades reaching 300 million for year 2025. The number of type 1 diabetics will also be increased but the majority of it will result from the increased number of type 2 diabetics. All types of diabetes are the consequence of a combination of genetic susceptibility and environmental factors, meaning that the prevention of diabetes epidemic cannot be done without the clarification of the genetic background. Significant progression has happened in the discovery of the genetic background of type 1 diabetes mellitus. It was helped by the etiologic classification of the disease: with the new classification the patient groups became more homogeneous. The HLA system is responsible for about 50-70% of the genetic risk while the effects of other genetic factors contribute 1-2% of the genetic susceptibility, respectively. Presently 25 gene regions are known as the different genetic factors of type 1 diabetes mellitus. Regarding the HLA system, the genes and pathomechanism causing the disease are not known. The classification of diabetes mellitus can be based on the HLA type while the predictability of type 1 diabetes mellitus is helped by the HLA type and the INS-VNTR. Much less is known about the genetic background of the polygenic type 2 diabetes mellitus. Its manifestation is now happening at younger age before. The best-fit genetic model consists of only a few genes with moderate effect superimposed on a polygenic background. Several „candidate” genes participating in the impaired insulin secretion and insulin action have already been investigated as the genes responsible for type 2 diabetes. These data showed the specificity in the population and most showed mild or modest association with the disease. Genomewide scans have resulted a number of significant diabetes susceptibility genes specific for a variety of populations, but these investigations have only resulted in the isolation of one gene (calpain 10) that is thought to contribute to type 2 diabetes. Most recent genomewide scans found loci on chromosome 20 in two different populations with significant segregation of type 2 diabetes. These loci are near to the region harboring the transcription factor hepatocyte nuclear factor genes. The transcription regulator HNF family is responsible for the regulation of the expression of several genes participating in the function of liver and pancreatic islet becoming a strong candidate for being a diabetes gene.]

[Asserting basis-bolus principle by analogue insulin preparations in pre-pubertal child with diabetes]


[INTRODUCTION - The choice of insulin combination therapy in children with type 1 diabetes mellitus is determined basically by the diet as well as the age of the patient. However, life rhythms of individual children are widely different. As a consequence, insulin therapy must be tailored to individual needs, by chosing the optimal one from the available insulin products with different efficacy curves. The aim is, of course, to maintain near-normoglycaemia for years or decades. CASE STUDY - The author presents the case of a 10-year-old girl with diabetes for 4 years, whose insulin treatment has involved a number of combinations. Good metabolic balance could be obtained by premixed insulin preparations for more than two years. However, subsequent intensive treatment with human insulins had poor results. This was primarily due to the fact that the child had a rather hectic daily schedule and eating habits, although she ate - appropriately for her age - six meals per day. After changing the ratios of the meals while maintaining her six-mealsper- day regime, an analogue glargine/glulisine combination therapy was induced, with a significant increase in the basal/ bolus ratio. This treatment was successful: HbA1c level got to the target range, without changes - theoretically caused by the rapid analogue - in hypo- and hyperglycaemic periods before and after small meals, respectively. CONCLUSION - During the time of remission, treatment with premixed human insulin can maintain good metabolic balance even for years, while saving (at least) two pricks per day. Insulin treatment intensified by analogue insulins (glulisine/glargine) may be attempted in prepubertal children needing six meals a day, provided their lifestyle raises problems. Glargine, given in an increased ratio, can compensate the hyperglycaemic effect of minimised small meals.]
