Positive airway pressure normalizes glucose metabolism in obstructive sleep apnea independent of diabetes and obesity

KABELOĞLU Vasfiye, SENEL Benbir Gulçin, KARADENIZ Derya

The relationship among obstructive sleep apnea syndrome (OSAS), type 2 diabetes mellitus (DM2) and obesity is very complex and multi-directional. Obesity and increased visceral fat are important perpetuating factors for DM2 in patients with OSAS. On the other hand, OSAS itself leads to obesity by causing both leptin and insulin resistance as a consequence of activation of the sympathetic nervous system. Risk for developing DM2 further increases in patients with OSAS and obesity. Data regarding effects of positive airway pressure (PAP) therapy, gold standard treatment for OSAS, on glycemic control were inconsistent due to variability in duration of and adherence to PAP therapy. In our cohort study we investigated effects of PAP treatment on glucose metabolism in normal-weighted non-diabetic OSAS patients, in obese non-diabetic OSAS patients, and in OSAS patients with DM2. We prospectively analyzed 67 patients diagnosed with OSAS and documented to be effectively treated with PAP therapy for three months. Apnea-hypopnea index was highest in the diabetic group, being significantly higher than in the normal-weighted group (p=0.021). Mean HOMA values were significantly higher in obese (p=0.002) and diabetic group (p=0.001) than normal-weighted group; the differences were still significant after PAP therapy. HbA1c levels were significantly higher in diabetic group compared to those in normal-weighted (p=0.012) and obese (p=0.001) groups. After PAP treatment, decrease in HbA1c levels were significant in normal-weighted (p=0.008), obese (p=0.034), and diabetic (p=0.011) groups. There was no correlation with the change in HbA1c levels and age (p=0.212), BMI (p=0.322), AHI (p=0.098) or oxygen levels (p=0.122). Our study showed that treatment of OSAS by PAP therapy offers beneficial effect on glucose metabolism, not only in diabetic patients, but also in obese and normal-weighted OSAS patients. Although data regarding overall effects of PAP therapy on glycemic control present contradictory results in the literature, it should be emphasized that duration and adherence to PAP therapy were main determinants for beneficial outcome of treatment.

[Epidemiology of diabetes mellitus and diabetes-related eye complications in Hungary]

TÓTH Gábor, NÉMETH János

[Diabetes mellitus is a disease of civilization and a leading cause of blindness among people of working age in developed countries. It’s prevalence is estimated to be 9.9% in the adult population in Hungary, based on this, the estimated number of people with diabetes mellitus was 807 000 in 2015 in our country. Almost every fifth people with diabetes mellitus has some form of diabetic retinopathy in Hungary. Among diabetic persons 0.3% is blind and 0.3% has serious visual impairment due to not adequately treated diabetes mellitus. The total prevalence-based diabetes retinopathy-associated economic burden was 43.66 billion HUF in 2018 in our country. The two major cost drivers were anti-VEGF injections and vitrectomies; they covered almost the four-fifths of the total cost among people with diabetes mellitus. We have to emphasize the importance of prevention, healthy nutrition and frequent sport activity in the fight against diabetes mellitus and overweight. With at least annually performed eye examinations in people with diabetes mellitus and timely treatment of diabetic retinopathy, visual impairment and blindness due to complications of diabetes mellitus can be prevented. ]

[Diabetes mellitus and hypertension - Facts, questions and thoughts]

KERÉNYI Zsuzsa, STELLA Péter, TAMÁS Gyula

[Using the new diagnostic criteria by WHO/ISH, the frequency of hypertension in type 1 diabetic patients is 15-61%, reaching 51-73% in type 2 cases. The combination of diabetes mellitus with hypertension increases the risks of stroke and cardiovascular diseases further compared to non-diabetic hypertensive patients. Authors review new recommendations concerning the diagnosis and treatment goals of hypertension in different types of diabetes mellitus. Most recent studies supporting these recommendations are also critically analysed. Theoretical advantages of new drugs and drug combinations in the therapy of hypertensive diabetics are reviewed. The strategy of treatment according to the cardiovascular riskprofile of diabetic patients is discussed in detail in the report. For the prevention of target-organ damage, the evidence based combination of ACE inhibitors and long-acting calcium channel blockers was strongly recommended. In about 70% of diabetic patients a combination of two drugs, in one-third of the cases a combination of three or four preparations seemed to be necessary, including low-dose diuretics and/or cardioselective beta-blockers. ]

[Tension type headache and its treatment possibilities]

ERTSEY Csaba, MAGYAR Máté, GYÜRE Tamás, BALOGH Eszter, BOZSIK György

[Tension type headache, the most common type of primary headaches, affects approximately 80% of the population. Mainly because of its high prevalence, the socio-economic consequences of tension type headache are significant. The pain in tension type headache is usually bilateral, mild to moderate, is of a pressing or tightening quality, and is not accompanied by other symptoms. Patients with frequent or daily occurrence of tension type headache may experience significant distress because of the condition. The two main therapeutic avenues of tension type headache are acute and prophylactic treatment. Simple or combined analgesics are the mainstay of acute treatment. Prophylactic treatment is needed in case of attacks that are frequent and/or difficult to treat. The first drugs of choice as preventatives of tension type headache are tricyclic antidepressants, with a special focus on amitriptyline, the efficacy of which having been documented in multiple double-blind, placebo-controlled studies. Among other antidepressants, the efficacy of mirtazapine and venlafaxine has been documented. There is weaker evidence about the efficacy of gabapentine, topiramate, and tizanidin. Non-pharmacological prophylactic methods of tension type headache with a documented efficacy include certain types of psychotherapy and acupuncture. ]

[Aspirin therapy in diabetes mellitus]

ÁBEL Tatjána

[Patients with diabetes mellitus have an increased risk of cardiovascular events and this risk is often present in the prediabetic phase of the type 2 diabetes. Diabetic patients have altered platelet function, including increased production of thombox ane resulting in increased platelet aggregation. This effect is reversed by aspirin within few days after beginning treatment with 75 mg aspirin daily. These findings of primary and secondary prevention trials in men and women with dia betes mellitus support the view that low-dose aspirin therapy should be used as secondary prevention when not contraindicated, and it should also be used as primary prevention in patients who are at high risk for cardiovascular events. ]

[Predictive factors for ischemic heart disease, diabetes mellitus and chronic kidney disease among hypertensive patients based on the data of the Hungarian Hypertension Registry 2011-2013-2015. Part I. Hypertensive population aged 35 to 64 years]

KÉKES Ede, PAKSY András, SZEGEDI János, JÁRAI Zoltán

[The association of hypertension with ischemic heart disease, diabetes and chronic kidney disease is the greatest therapeutic challenge because these associations significantly increase mortality and deteriorate life expectancy. It is important for the clinician to clarify the predictive factors of each association for successful prevention or slowing the progression of diseases. According to the database of the Hungarian Hypertension Registry 2011-2013-2015, 11,137 men and 11,112 women with hypertension and comorbidities (CHD, diabetes, CKD) aged between 35 and 64 were analyzed for the purpose of assessing the predictive value of the traditional risk factors in co-morbidity. We analyzed the predictive weight of each variable with single- and multi-variable stepwise logistic regression, and reported Odds ratio (OR, odds ratio). In patients with hypertension aged 35-64 (male / female), the prevalence of CHD was 41.6% / 35.8%, diabetes 27.1% / 23% and KVB 16.2% / 33.8%, respectively. The chance of developing CHD is highest in hypertensive individuals (male/female) who have diabetes (OR 1.30/1.48), who are obese (OR 1.22/1.21), who smoke (OR 1.50/1.51), and whose blood pressure >140/90 mmHg (OR 1.23/1.29). The dominant predictive factors of type 2 diabetes are obesity (visceral obesity) (OR 1.46/1.49), low HDL cholesterol (OR 1.32/1.35), and high triglyceride levels (OR 1.20/1.42); in women the uric acid level also showed high odds ratio (OR 1.39). There is a significant chance of developing chronic kidney disease in hypertension in both sexes, if abnormal uric acid levels (OR 1.73/1.46) and inadequate treatment of high blood pressure (>140Hgmm SBP) (OR 1.43/1.19) are present. In women, the abnormal triglyceride level) also showed a high odd (OR 1.81).]

[Type 2 diabetes: what is the role of a General Practitioner in the treatment of diabetes?]

TORZSA Péter, OLÁH Ilona, HARGITTAY Csenge, KALABAY László

[The 2017 National Guidelines of the Hun­garian Diabetes Association emphasize the individual treatment of diabetic patients and the strong, goal-oriented regulation of carbohydrate metabolism from recogni­tion on. Beside monotherapy, primary dual or triple combination therapy may be applied in the treatment of patients. In primary care it’s the treatment of patients with type 2 diabetes where there is a lot to be done. We hope that the everyday use of the Professional Guidelines will contribute to a more successful diabetic care by General Practitioners (GPs). The holistic care of the GP’s team plays an important role in the primary, secondary and tertiary prevention of Type 2 diabetes, which accounts for more than 90% of all diabetic cases. ]

[Potential benefits of using GLP1-receptor agonists during COVID-19 epidemic]

KIS János Tibor, SCHANDL László, GRÓSZ Andrea

[The risk of SARS-CoV-2 infection is higher among diabetic patients. The severity of progressing infection also increases in diabetes mellitus. Obesity associated with diabetes and cardiovascular disease are worsening the prognosis. Glucagon-like peptide-1 receptor agonists (GLP1-RA) administered in type 2 diabetes are lowering significantly the blood sugar level without increasing the risk of hypoglycaemia, support patients to lose weight, and reduce the likelihood of developing and worsening car­diovascular diseases. Through their many effects, they prepare diabetic patients to a certain extent to survive SARS-CoV-2 infection with fewer complications and have a beneficial immunological effect against the development of cytokine storm respectively. The authors summarize the potential beneficial effects of GLP1-RAs in SARS-CoV-2 infection.]

[GLP-1 receptor agonists in the treatment of type 2 diabetes]

WINKLER Gábor

[The glucagon-like peptide (GLP)-1 receptor agonists and somewhat later, the sodium-glucose cotransporter (SGLT) -2 inhibitors have brought new perspectives in the antihyperglycemic treatment of type 2 diabetes. The article overviews clinicopharmacologic characteristics of the GLP-1 receptor agonist group, their glycemic and non-glycemic effects, results of the cardiovascular endpoint studies as well as their place in the recent therapeutic guidelines. It is proven, that both glycemic and weight reducing effect is greater of the long-acting (non-prandial) coumpounds as compared to that of the short acting (prandial) derivates, further, that in studies with cardiovascular endpoints they reduced the relative risk of the composite endpoint of non-fatal myocardial infarct, non-fatal stroke and cardiovascular death. Due to the favolurable glycemic and non-glycemic properties their use is advised already in the early course of type 2 diabetes, as combination of the metformin therapy.]

[Metabolic syndrome - metabolic risk factors]

AUDIKOVSZKY Mária, PADOS Gyula

[Since abdominal type obesity, diabetes mellitus and the metabolic syndrome were classified as primary coronary risk factors beside hypercholesterolaemia and smoking, five out of six of the most significant risk factors are regarded of metabolic origin. Simultaneous occurrence of these factors are far more frequent in the population. The composition and background of this syndrome were subject of numerous analyses and classification from syndrome-X to metabolic syndrome. Reaven finds insulin resistance and compensatory hyperinsulinism as the primary cause, while Matsuzava et al regards visceral type obesity (visceral fat syndrome), and Björntrop views the increase in sympathetic tone (civilization syndrome) as fundamental. In the diagnostics and therapy of the metabolic syndrome we should consider all factors mentioned above. We have to establish the presence of three or more classic risk factors for a firm diagnosis. In the therapy, decreasing the body weight with diet and exercise is crucial, with adjuvant drug therapy of antidiabetics, insulinsensitizers, lipid lowering agents and antihypertensives, as needed. ]
