[Role of nephroclinicopathology in the nephrological diagnosis]

NAGY Judit, KEMÉNY Éva, IVÁNYI Béla

[In cases where a definitive diagnosis of a renal disease cannot be established on the basis of the clinical and laboratory data as well as imaging techniques the histological examination of the renal biopsy can be useful for establishing a pathological diagnosis, assessing the prognosis and can give etiopathogenetic information to guide the further management. The description and the degree of the active and chronic changes may influence the rationale treatment and the likelihood of the response. However, discussion between the nephrologist and the nephropathologist is indispensable at the decision to take the biopsy and at the evaluation of the result of the histological examination.]

[Diagnostic of genetic factors affecting blood pressure and the genetic risk factorsof hypertension]

LACZIKÓ Dorottya, RÉPÁSI Eszter, RZEPIEL Andrea, KEREKES Éva, SHENKER-HORVÁTH Kinga, KOLLER Ákos, ELBERT Gábor, NAGY Zsolt B.

[Hypertension is a risk factor of cardiovascular and renal diseases. Although high blood pressure usually does not show symptoms, it can lead to serious health problems such as stroke or cardio and renal insufficiency. Globally 40% of adults over the age of 24 suffer from hypertension, and the risk increases with age. The incidence is more than 70% over 65 years of age. Environmental and genetic effects are jointly responsible for the onset of hypertension, thereby determining predisposing genes is extremely difficult. Genetic variations of several genes have been identified to increase the risk of hypertension. The most common hypertension susceptibility polymorphisms occur in AGT, AGTR1, ACE, NOS3 and CYP4A11 genes. Learning about polymorphisms has clinical importance both in prevention and therapeutic processes. Therapeutic and lifestyle recommendations can be individualized by using molecular genetic tests such us PCR, microarrays, real-time PCR.]

[Application of central sympatholytic agents and vasodilators between 2007-2014 based on OEP’s database]

BARNA István, GYURCSÁNYI András

[Due to the a large number of antihypertensive drugs on the Hungarian market, in the light of the constantly updated recommendations for therapy, seemed to be worth to consider the traffic data provided by the National Health Insurance. We analysed the turnover of the centrally-acting and direct vasodilator antihypertensive, using the data of The National Health Insurance Fund (NHIF) between 2007 and 2014. Every year the December data were comparesed, the turnover of the month did not substantially different from other month, an average of 5-6 million boxes of cardiovascular products are prescribed. Over the past seven years it was fluctuating, but overall there was almost 19% increase in the turnover of centrally acting medicinal products. The prescription number of guanfacine decreased almost one-third, moxonidine orders fell 37%, while the turnover of rilmenidine doubled during that same period. A significant expansion of the centrally acting rilmenidine became clear in the domestic market. The minimal side effects, the favourable profile of applications, the number of international and domestic studies make it an excellent second-third additional agent. The use of vasodilators overall increased of a small degree (15%), mainly due to a 53% increase of doxazosin. Considering the domestic prescribing habits they follow very well the international and domestic recommendations. The observed differences in each group are the effects of the positive results of recent studies.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

[The connection between the socioeconomic status and stroke in Budapest]

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]
