Nyúltvelői neurovascularis kompresszió. A szekunder hypertonia ritka oka.

Compression of the rostral ventrolateral medulla oblongata is one of the rarely identified causes of refractory hypertension. In patients with severe, intractable hypertension caused by neurovascular compression, neurosurgical decompression should be considered. The authors present the history of a 20-year-old man with severe hypertension. After excluding other possible causes of secondary hypertension, the underlying cause of his high blood pressure was identified by the demonstration of neurovascular compression shown by magnetic resonance angiography and an increased sympathetic activity (sinus tachycardia) during the high blood pressure episodes. Due to frequent episodes of hypertensive crises, surgical decompression was recommended, which was performed with the placement of an isograft between the brainstem and the left vertebral artery. In the first six months after the operation, the patient's blood pressure could be kept in the normal range with significantly reduced doses of antihypertensive medication. Repeat magnetic resonance angiography confirmed the cessation of brainstem compression. After six months periodically increased blood pressure returned, but in smaller extent and less frequent. Based on the result of magnetic resonance angiography performed 22 months after surgery, re-operation was considerd. According to previous literature data long-term success can only be achieved in one third of patients after surgical decompression. In the majority of patients surgery results in a significant decrease of blood pressure, an increased efficiency of antihypertensive therapy as well as a decrease in the frequency of highly increased blood pressure episodes. Thus, a significant improvement of the patient's quality of life can be achieved. The case of this patient is an example of the latter scenario. Orv. Hetil., 2014, 155(21), 838-842

A cukorbeteg-ellátás mutatóinak alakulása Magyarországon 2001–2014 között. Az Országos Egészségbiztosítási Pénztár adatbázis-elemzésének célja és módszertana

In the last couple of years, database analyses have become increasingly popular among clinical-epidemiological investigations. In Hungary, the National Health Insurance Fund serves as central database of all medical attendances in state departments and purchases of drug prescriptions in pharmacies. Data from in- and outpatient departments as well as those from pharmacies are regularly collected in this database which is public and accessible on request. The aim of this retrospective study was to investigate the database of the National Health Insurance Fund in order to analyze the diabetes-associated morbidity and mortality in the period of years 2001-2014. Moreover, data of therapeutic costs, features of hospitalizations and practice of antidiabetic treatment were examined. The authors report now on the method of the database analysis. It is to be hoped that the upcoming results of this investigation will add some new data to recent knowledge about diabetes care in Hungary. Orv. Hetil., 2016, 157(32), 1259-1265

A 2-es típusú diabetes antihyperglykaemiás kezelésének alakulása Magyarországon 2001–2014 között – az Országos Egészségbiztosítási Pénztár adatbázis-elemzésének eredményei

In the last couple of years, significant developments in antidiabetic treatment have influenced the pharmacological treatment of type 2 diabetes mellitus (T2DM). The aim of this study was to analyze the changes in prescribing patterns of glucose-lowering drugs for T2DM patients in Hungary between 2001 and 2014. The number of patients with newly diagnosed T2DM decreased from 75,700 (2001) to 33,700 (2014), while prevalent T2DM cases continuously increased and plateaued in 2014 with a number of registered patients of 727,000. Sulfonylurea-monotherapy decreased from 64% to 35% while metformin-monotherapy increased from 19% to 42% in this period. The most frequently used drug at first treatment initiation was metformin (66%) and sulfonylurea (16%) as monotherapy in 2014. DPP4-inhibitors were newly administered in 20,362 cases while GLP1-mimetics were newly used by 4,996 patients in 2014. Five years later after initiating sulfonylurea therapy between 2010 and 2014, metformin was more frequently used as second drug (39%) than sulfonylurea in patients with previous metformin treatment (22.9%). The prescribing patterns of glucose-lowering drugs have changed over time in accordance with new guidelines. Further changes in prescribing habits can be expected in the near future.

Neutrophil-to-Lymphocyte Ratio Is an Independent Risk Factor for Coronary Artery Disease in Central Obesity

Several inflammatory biomarkers were found to be associated with an increased risk of cardiovascular disease. Neutrophil-to-lymphocyte ratio (NLR) is a marker of subclinical inflammation that increases with the stress response. Visceral adiposity index (VAI) calculated as a combination of anthropometric and metabolic parameters reflects both the extent and function of visceral adipose tissue. Given the association of subclinical inflammation with both obesity and cardiovascular diseases, it is plausible that the inflammation-CVD association is modulated by the amount and function of adipose tissue. Thus, our aim was to examine the association between NLR and coronary artery calcium score (CACS), an intermediate marker of coronary artery disease in asymptomatic patients across VAI tertiles. Methods: Data from 280 asymptomatic participants of a cardiovascular screening program were analysed. In addition to the collection of lifestyle and medical history, a non-contrast cardiac CT scan and laboratory tests were performed on all participants. Multivariate logistic regression was conducted with CACS > 100 as the outcome and with conventional cardiovascular risk factors and NLR, VAI, and NLR by VAI tertile as predictors. Results: We found an interaction between VAI tertiles and NLR; NLR values were similar in the lower VAI tertiles, while they were higher in the CACS > 100 in the 3rd VAI tertile (CACS ≤ 100: 1.94 ± 0.58 vs. CACS > 100: 2.48 ± 1.1, p = 0.008). According to multivariable logistic regression, the interaction between NLR and VAI tertiles remained: NLR was associated with CACS > 100 in the 3rd VAI tertile (OR = 1.67, 95% CI 1.06-2.62, p = 0.03) but not in the lower tertiles even after adjustment for age, sex, smoking, history of hypertension, hyperlipidaemia, and diabetes mellitus, as well as high-sensitivity C-reactive protein. Our findings draw attention to the independent association between subclinical, chronic, systemic inflammation and subclinical coronary disease in obesity

Correlation of same-visit HbA1c test with laboratory-based measurements: A MetroNet study

BACKGROUND: Glycated hemoglobin (HbA1c) results vary by analytical method. Use of same-visit HbA1c testing methodology holds the promise of more efficient patient care, and improved diabetes management. Our objective was to test the feasibility of introducing a same-visit HbA1c methodology into busy family practice centers (FPC) and to calculate the correlation between the same-visit HbA1c test and the laboratory method that the clinical site was currently using for HbA1c testing. METHODS: Consecutive diabetic patients 18 years of age and older having blood samples drawn for routine laboratory analysis of HbA1c were asked to provide a capillary blood sample for same-visit testing with the BIO-RAD Micromat II. We compared the results of the same-visit test to three different laboratory methods (one FPC used two different laboratories). RESULTS: 147 paired samples were available for analysis (73 from one FPC; 74 from the other). The Pearson correlation of Micromat II and ion-exchange HPLC was 0.713 (p < 0.001). The Micromat II mean HbA1c was 6.91%, which was lower than the 7.23% from the ion-exchange HPLC analysis (p < 0.001). The correlation of Micromat II with boronate-affinity HPLC was 0.773 (p < 0.001); Micromat II mean HbA1c 6.44%, boronate-affinity HPLC mean 7.71% (p < 0.001). Correlation coefficient for Micromat II and immuno-turbidimetric analysis was 0.927 (p < 0.001); Micromat II mean HbA1c was 7.15% and mean HbA1c from the immuno-turbidimetric analysis was 7.99% (p = 0.002). Medical staff found the same-visit measurement difficult to perform due to the amount of dedicated time required for the test. CONCLUSION: For each of the laboratory methods, the correlation coefficient was lower than the 0.96 reported by the manufacturer. This might be due to variability introduced by the multiple users of the Micromat II machine. The mean HbA1c results were also consistently lower than those obtained from laboratory analysis. Additionally, the amount of dedicated time required to perform the assay may limit its usefulness in a busy clinical practice. Before introducing a same-visit HbA1c methodology, clinicians should compare the rapid results to their current method of analysis

Relapsing insulin-induced lipoatrophy, cured by prolonged low-dose oral prednisone: a case report

<p>Abstract</p> <p>Introduction</p> <p>Circumscript, progressing lipoatrophy at the insulin injection sites is an unexplained, however rare condition in diabetes mellitus.</p> <p>Case presentation</p> <p>We report a case of severe localised lipoatrophy developing during insulin pump-treatment (continuous subcutaneous insulin infusion) with the insulin analogue lispro (Humalog^®) in a woman with type-1 diabetes mellitus. After 11 months of progressing lipoatrophy at two spots on the abdomen, low-dose prednisone (5-10 mg) p.o. was given at breakfast for 8 months, whereby the atrophic lesions centripetally re-filled with subcutaneous fat tissue (confirmed by MRI) despite ongoing use of insulin lispro. However, 4 weeks after cessation of prednisone, lipoatrophy relapsed, but resolved after another 2 months of low-dose prednisone. No further relapse was noted during 12 months of follow-up on insulin-pump therapy with Humalog^®.</p> <p>Conclusion</p> <p>Consistent with an assumed inflammatory nature of the condition, low-dose oral prednisone appeared to have cured the lipoatrophic reaction in our patient. Our observation suggests a temporary intolerance of the subcutaneous fat tissue to insulin lispro (Humalog^®), triggered by an unknown endogenous mechanism.</p
