[Introduction: Rapidly progressive glomerulonephritis is life-threatening manifestation of antineutrophil cytoplasmatic antibody (ANCA)-associated vasculitis (AAV), often diagnosed only in advanced stage of renal failure. In 2010 a new histopathologic classification of ANCA- associated vasculitis was published by an international working group of nephropathologists. Vasculitis cases were classified in four groups: focal, crescent, mixed and sclerotic. Method: The aim of our study was to re-evaluate the predictive value of this new classification regarding renal outcome. From the 88 patients with ANCA-associated vasculitis treated in our department from 1996 to 2013, 39 were involved. Results: By retrospective evaluation of biopsy samples, patients were classified as 11 in focal, 12 in crescent, eight in mixed, eight in sclerotic group. There was no significant difference among the four groups regarding the mean age, sex, ANCAtype and initial eGFR. Due to the treatment, the eGFR values significantly increased in the focal and in the crescent groups. Eleven patients needed dialysis at presentation and three of them recovered, none of them belonged to the sclerotic group. The cumulative renal response to treatment was 100% in the focal, 87.5% in the mixed, 64% in the crescent and 62% in the sclerotic group. Renal response at one year treatment was 80%, thirty-one of the thirty-nine patients were dialysis independent. All patients were alive at one year, by year five two patients from the sclerotic group died. Conclusion: The new nephropathological classification of AAV is useful in predicting the renal response to treatment. Nephropathology can optimize the system by mentioning the specific percentage of normal glomeruli in the biopsy specimen.]

[Blood presssure paradoxon in very elderly patients]


[The paper is warning for the necessity of very complex consideration before taking antihypertensive therapeutic decisions (indication, point or points of actiou, blood pressure target levels, dynamics of BP reduction, etc) for elderly hypertensive patients. Blood pressure reduction can mean efficient protection against cardiovascular events also among the elderly hypertensives. However in those old and very old hypertensive patients who have not only severe stiffness of their large vessels but suffer in advanced co-morbidities and integrated pathologic geriatric syndromes, the blood pressure reduction can result in sometimes even life threatening general deterioration. Antihypertensive therapeutic dilemmas of elderly caregivers appear mainly in relation to old hypertensive patients of age over 80 years. For this „very old” age period the HYVET study gave us evidence based conclusions about the cardiovascular protective usefulness of combined antihypertensive treatment resulting in BP reduction to 150 Hgmm systolic BP target levels. However a non-negligable rate of selection of the included patients in HYVET study can weaken the generalizability of the HYVET findings in this age period and the extensibility of its antihypertensive therapeutic conclusions for the entire „very old” population because this population has also a high proportion of patients with chronic progressive illnesses and general decline. Thus the elderly hypertensives’ caregiver must always carefully and critically balance between the messages of the HYVET and the nonselective observational follow up studies among elderlies showing frequently the so-called epidemiologic blood pressure/ mortality paradoxon. The paper is also trying to find potencial pathomechanical interpretations and point of actions for the epidemiologic blood pressure/mortality paradoxon found in the very old population.]

[The beginnings and difficulties of peritoneal dialysis at the end of the last century. Part II. Hungarian experiences]


[In Part I, I summarised the beginnings, the theoretical background and the international experiences of peritoneal dialysis. Hungarian publications related to peritoneal dialysis in the 1950s were focusing on the role of the method in the treatment of chronic renal disorders. The first dialysis centres were established in the medical universities of Hungary (Szeged in 1955, Budapest in 1960, Pécs in 1964, Debrecen in 1970) and in Miskolc in 1968. Despite the restricted hemodialysis capacities the intermittent technique of peritoneal dialysis did not spread in accordance with the demand. A survey conducted at the beginning of the 1970’s in the territory of the five counties with 1.5 million inhabitants revealed that considering the numbers of patients with renal diseases requiring dialysis, developing of a network of care and increasing the dialysis capacities is necessary and so is the development of a system of szatellite peritoneal dialysis, which was implemented with our support in 10 units of the county hospitals. A devoted and enthusiastic organiser of the nation-wide system of peritoneal dialysis was professor Taraba, who, due to his untimely death, was deprived of seeing the nation-wide spread of CAPD. At the beginning of the 1980’s the first reports on the favourable effects of CAPD appeared in Hungary. Solutions prepared in pharmacies and the lack of up-to-date equipment resulted in the frequent occurrence of peritonitis. In addition, the unfavourable memories of dialysis performed with bottled solutions (long treatment times, frequently peritonitis) were still vivid among patients and colleagues supervising the treatment. As a consequence, our survey conducted in 1991 revealed that the spread of CAPD all over the world in Hungary resulted in a significant increase of those treated with the intermittent method (more than 10% of the dialysis patients), while those treated with CAPD remained under 2%. Several reports on CAPD and the consequences that followed from them as well as the further training organised in the Szent Margit Hospital, Budapest and in Gánt, and also the guidelines issued by the Society of Hungarian Nephrologists the number of those treated with dialysis has exceeded 6000 in the past decade. 10% of them received CAPD/APD treatment.]

[Ways and tools of the organism's defence in atherosclerosis - The mysterious HDL particle]


[Every type of injury elicits an immediate defending, preventing response in the living organism, which involves the whole organism’s participation. In case of a single effect, the events and symptoms together can be designated as “acute phase reaction syndrome”. The pathogenic constituents' effects on the arterial wall are, however, permanent, though varying in composition and intensity. The protecting reaction serving the prevention of the continuously arising vessel wall lesion is inflammation itself. Beginning of the inflammatory phenomenon carries within itself the criteria of the acute tissue response but it takes on involuntarily chronic features as a consequence of the chronic etiology. In the arterial wall ongoing vasculitis affects all the three layers of the vessels. The HDL particle is involved in triggering and progression of vasculitis. It transports cholesterol from the tissues to the liver, defends the integrity and physiological functions of the endothelium, exerts antioxidant effects, and it has the capacity to inhibit secretion and effects of cytokines, cell migration and the thrombotic process. These are all together serving as controllers of the ongoing vasculitis in the artery wall. Composition of the HDL particle is exceptionally complex. Almost half of the identifiable - at least 48 - components could be considered as acute phase reactants, and almost as many are related to cholesterol and lipoprotein metabolism. Participation of proteinase inhibitors and complement system components and regulators is very important for its function. Some constituents have a glycosaminoglycan binding capacity. The physiological roles of some acute phase reactants are not completely identified as today. This is especially valid concerning the characteristics of the HDL particle as an entity. Nevertheless, on the basis of present study data, it is ascertainable that HDL is an acute phase reactant; it is an inherent part of the natural, innate immune system of the organism. However, it is only one single component of the large group of the anti-inflammatory mechanisms and factors.]

[Polyneuropathy as a first sign of microscopic polyangiitis]

ZÖLD Éva, HORVÁTH Ildikó Fanny, TARJÁN Péter, BARTA Zsolt, ZEHER Margit

[INTRODUCTION - Microscopic polyangiitis (MPA) is a systemic autoimmun disease characterized by necrotizing small vasculitis. MPA belongs to the ANCA-associated vasculitides. The disease can affect many of the body’s organ systems. Major organs involved are kidneys, skin, peripheral nerves and lungs. In addition, generalized symptoms such as fever and weight loss are very common. CASE REPORT - In January 2013 a 56-year old woman presented with weight loss, lower leg numbness, walking difficulty and petechiae on the lower legs. One month later, laboratory examinations showed progressive kidney dysfunction, anemia, hypersedimentation and elevated C reactive protein level, but further tests and investigations for potential bacterial infection and tumors were all negative. In sum, clinical signs and symptoms suggested systemic vasculitis, which was proved by the kidney biopsy and ENG examination. From these findings, microscopic polyangiitis was diagnosed with polyneuropathy and glomerulonephritis. The patient was a Hepatitis B (HBV) virus carrier, which can be provoking factor for vasculitis. Corticosteroid and six treatment cycles of intravenous pulse cyclophosphamide were performed for induction of remission. After treatment her symptoms improved and kidney function was normalized. Antiviral treatment was started because of HBV reactivation in October 2013. As a new manifestation of MPA, pulmonary symptoms were appeared in November 2013 and the patient was treated with synchronization of plasmapheresis and pulse cyclophosphamide with good clinical effectivity. Now, she is treated with methotrexate as immunosuppressive treatment and control examinations indicate the remission of the disease with proper renal function. CONCLUSION - We draw attention to a rare case of vasculitis and underline the importance of both the early diagnosis and the early and effective immunosuppressive therapy. Peripheral neuropathy may occur as a result of having systemic vasculitis. Nevertheless, the exploration and elimination of provoking factors are also must be part of the management and the regular follow-up is essential to recognize the disease relapses, thus avoid permanent organ damage.]

[INTRODUCTION - Vasculitis is an inflammatory disorder of the vessels, often associates with necrosis. The primary (idiopathic) form caused by distinct immunological mechanisms, the secondary form caused by infection, tumor, drugs or systemic autoimmune disease. CASE REPORT - 57-year-old smoking female patient with a medical history of the left ankle fracture. Four days earlier had sore throat, at admission was febrile and generally weak and had severe pain in her lower extremities. Physical examination revealed numerous livid alterations in both lower extremities, necrotic change of some toes and new onset of diastolic hypertension. Elevated serum transaminase levels, severe thrombopenia, anemia, leukocytosis suggested the possibility of thrombotic thrombocytopenic purpura and vasculitis. Tests ruled out septic embolism, therefore we applied high dose steroid treatment and plasma exchange. Meanwhile the results fulfilled the classification criteria of polyarteritis nodosa (vasculitis, livedo reticularis, polyneuropathia and new onset of diastolic hypertension), accordingly we synchronized the treatment with fractionally administered intravenous cyclophosphamide. The process revealed responsive to therapy and the substantive function of the legs remained after surgical removal of the necrotic areas. CONCLUSIONS - Early rapid diagnosis of vasculitis is fundamental and we emphasize the significance of the efficient treatment.]
