[Subtype diagnosis, treatment, complications and outcomes of primary aldosteronism and future direction of research: a position statement and consensus of the Working Group on Endocrine Hypertension of the European Society of Hypertension – excerpts]

KOVÁTS Viktória, ALFÖLDI Sándor

[Primary aldosteronism is a frequent cause of secondary hypertension requiring a specific pharmacological treatment with mineralocorticoid receptor antagonist or with unilateral adrenalectomy. These treatments have shown to reduce the excess of cardiovascular risk characteristically associated with this disease. In this consensus, we discussed the procedures for the diagnosis of primary aldosteronism, we address the strategies for the differential diagnosis of primary aldosteronism subtypes and therapy. We also discuss the evaluation of outcomes and provide suggestions for follow-up as well as cardiovascular and metabolic complications specifically associated with primary aldosteronism. ]

[Unattended automated office blood pressure measurement versus classic office automated blood pressure measurement in a hypertension outpatient clinic]


[Accurate measurement of blood pressure is a fundamental prerequisite requirement for an appropriate management of arterial hypertension. In order to eliminate the well-known limitations of classic office blood pressure measurements, the so-called unattended automatic office blood pressure measurement method can be a solution. In 52 patients arriving for regular followup into one of the Hypertension Outpatinet Clinic of the Nephrology-Hypertension Center of the University of Szeged 3-3 blood pressure measurements were made at 1-1 minute intervals first by a doctor with an MIT5 automatic device and then in a separate room unattended, starting alone by the patient with a Hem-907 device. ]

[Effect of beta-blockers with or without vasodilating properties on central blood pressure]


[Beta-blockers are more and more excluded as frist-line option in recent hypertension guidelines – they are mainly used in the case of compelling indication. However beta-blockers are not a homogeneous drug-class as several differences exist between them regarding their effect on metabolism or vasoconstriction/vasodilation. The clinical implication of central blood pressure has recently arisen into the focus of interest in the light of the fact that different antihypertensives exert different effect on central blood pressure. The theory of ”stiffness-gradient” may help us to deepen our knowledge regarding the physiology of central blood pressure. Several studies investigated the effects of different beta-blockers on central blood pressure. Based on the unique effect of beta-blockers with vasodilating properties it can be emerged to form this group of drugs as a new antihypertensive class. ]

[Hypertension, cognitive function and dementia – Significance of antihypertensive therapy]

GAJDÁN Nikolett, ÁBRAHÁM György

[The significance of hypertension as one of the major cardiovascular risk factor is unquestionable. By achieving target blood pressure values differentiated by age and comorbidities, the risk of cardiovascular events can be significantly reduced. However, it is essential to the quality of life the patient spends the extra years of life thus gained. This is a really complex issue affecting many co-disciplines, but one of the most important of these is the mental health, maintaining cognitive functions, and avoiding dementia. High blood pressure impairs the blood supply to the target organs, including the brain, by damaging the smooth muscle of the arteries and accelerating atherosclerosis, which increases the risk, the frequency and the severity of mental decline in proportion to the degree of tension. This means serious implications not only for the individual, but for the family and the society, as well. A particular contradiction is that treating blood pressure to the target range does not automatically means preserving cognitive functions and avoiding the risk of dementia. Meta-analyzes of large studies have shown differences between the individual antihypertensive groups have been confirmed in this respect as well. Inhibitors of the renin-angiotensin system and calcium antagonists – mainly dihydropyridines – appear to be a priority in this regard. The authors provide an overview of the relationship between hypertension and mental abilities, with a review of the literature on the effects of antihypertensive therapy, with particular reference to the effects on cognitive function and dementia. ]

[Lupus nephritis, 2022]

CZIROK Szabina, DOLGOS Szilveszter

[The lupus nephritis (LN) is one of the most frequent manifestation of SLE which causes higher morbiditiy and mortalitiy of the patients if it appears. Although the use of glucocorticoides, cyclophosphamide and mycofenolat mofetil and the protection of the kidney with conservative therapy has significantly improved the outcome of the disease, but the long-term renal outcome and risk of death from LN have not changes over the last 20 years. Furthermore, the side effect of our medications used as part of the standard immunomodulatory therapy are not negligible. The better understanding of the pathomechanism of different medical conditions (hypertension, diabetes mellitus etc.) has helped to combine medications with different therapeutic targets which result more effective and favorable side-effect profile therapy. Therefore, it is not suprising that, in parallel with improvement of the immunology, with better knowlege about the patomechanism of SLE can lead to the new combined, targeted treatments which have broadened the therapeutic options. In addition to the immunmodulatory therapy, a drug with new mechanism of action has become available to slow the progression of chronic kidney diseases. The purpose of this summary is to briefly summarize the current knowledge available and assist clinicians in the daily practice of patients with LN to give suggestion for more effective and personalized therapeutic options.]

[Prominents in Hungarian nephrology Professor Gyula Petrányi (1912-2000). Part II]


[A nation can only survive and keep its identity through its traditions. This is why the initiative to launch this series coming from professor János Radó is worthy of attention. Gyula Petrányi is an outstanding personality in 20th century internal medicine, to be more precise in nephrology and immunology, his activity being wide-ranging. The first part of the current summary of his work deals with a tribute to his personality, and his role in immunomodularity treatment in glomerulonephritis. The second part shall cover his role in spreading renal biopsy, screening and caring kidney patients, dialysis, in developing kidney patients’ care, furthermore in clinicopharmacology and renal transplantation.]

[Primary tubulointerstitial nephritis is characterised by an inflammatory infiltrate of tubulointerstitial space. The infiltrate consists of T and B lymphocytes, monocytes, macrophages, neutrophyl and eosinophyl granulocytes in varying degree. It is associated with interstitial oedema and different level of tubular damage. The disease exists in acute and chronic form. The main causes of this condition are: drugs, infection, systemic diseases, malignancy and in some cases the disease is idiopathic. The pathogenesis in most cases is immune-mediated. The secondary form of tubulointerstitial nephritis can occur in primary glomerular and vascular disease and is characterised by tubulointerstitial fibrosis and tubulus atrophy. The morphological alterations are major determinants of the progression of chronic renal disease. In both forms of tubulointerstitial nephritis the development of renal insufficiency is often observed.]

[Role of nephroclinicopathology in the nephrological diagnosis]


[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.]

[Tubulointerstitial nephritis and uveitis syndrome]


[Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare and underdiagnosed oculorenal disorder that is characterized by the development of acute tubulointerstitial nephritis and uveitis. The median age of onset is 15 years, but it may occur at any age. There is a female predominance. Uveitis might occur before, after, and also concomitantly with tubulointerstitial nephritis. The symptoms are typically non-specific, including fever, loss of appetite, weight loss, nausea and vomiting, weakness, abdominal pain, arthralgias and myalgias. Laboratory findings reveal an acute impairment of renal function, anaemia and elevated inflammatory parameters. Urinary findings are consistent with tubulointerstitial nephritis including subnephrotic proteinuria, sterile leucocyturia, microhaematuria, and tubular dysfunction (e.g. normoglycemic glycosuria). The prognosis appears to be good, especially in children. Persistent renal dysfunction only develops in a small proportion of cases. In this paper, we present the case of a 39-year-old female patient with TINU syndrome, and review the literature.]
