[Systemic ANCA-associated vasculitis. Induction immunosuppression therapy, complications and outcome. Part 2]

HARIS Ágnes, POLNER Kálmán

[The present review is compiled of two parts, the first part aims to summarize the induction immunosuppressive therapy, the second part delineates the outcome and complications of ANCA-associated vasculitis. ANCA-associated vasculitis is a systemic disease, accompanied with rapidly progressive glomerulonephritis and severe, often life-threatening extrarenal complications. By early diagnosis and immediate initiation of immunosuppressive therapy both patient and renal outcome have been substantially improved. The major aims of modern therapeutic protocols are, besides improving survival, to decrease immunosuppressive drug toxicity and avoid infections. Immunosuppression is based on the combination of large dose of corticosteroid and cyclophosphamide, which is advisable to supplement by plasma exchange. The B-cell depleting anti-CD20 monoclonal antibody rituximab, which has already been available in Hungary, has been proved to be similarly effective in newly diagnosed ANCA-vasculitis, and even more effective in a relapsing disease, compared to cyclophosphamide. Amongst rituximab’s further indications in this disease is the preservation of young women’s fertility, and it also has priority in some other special cases. Early diagnosis and prompt immunosuppressive treatment have resulted that ANCAvasculitis became a treatable disease with reasonably good clinical outcome, yet both the disease and the immunosuppressive medications frequently cause complications, which necessitate continuous alertness of the attending nephrologists.]

[Isolated systolic hypertension in the elderly and very elderly]


[In the elderly (˃65 yrs) and very elderly (˃80 yrs) large clinical investigations showed that isolated systolic hypertension is the most frequent form of hypertension. In the background, several cardiovascular, neural and hormonal changes have been proved. One of the most important pathogenetic factor is the increase of arterial stiffness. This leads to the increase of pulse wave velocity and systolic blood pressure, and also to the decrease of diastolic blood pressure. Consequently, pulse pressure increases. All these factors contribute to the increase in incidence and prevalence of cardiovascular consequences of hypertension, which are more frequent than in younger ages.]

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.

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study


Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.

[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. ]

Acute effect of sphenopalatine ganglion block with lidocaine in a patient with SUNCT


Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing/short-lasting unilateral neuralgiform headache with cranial autonomic features (SUNCT/SUNA) is a rare severe headache. At the time of an attack, it can hinder a patient from eating and requires acute intervention. The sphenopalatine ganglion is an extracranial parasympathetic ganglion with both sensory and autonomic fibers. Sphenopalatine ganglion block has long been used in the treatment of headache, particularly when conventional methods have failed. Here, we present a patient who was resistant to intravenous lidocaine, but responded rapidly to sphenopalatine ganglion block during an acute episode of SUNCT/SUNA.

The applications of transcranial Doppler in ischemic stroke


Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.
