[Effect of mycophenolate sodium therapy on quality of life of renal transplant patients]

[Enteric-coated mycophenolate sodium (EC-MPS; Myfortic®, Novartis Pharma AG, Basel, Switzerland) is an enteric-coated formulation delivering MPA. Enteric-coated MPS has been developed with the aim of improving the upper GI tolerability of MPA while providing a therapeutical equivalence. The primary objective of the study was to measure the quality of life of kidney transplant patients, with special attention to gastrointestinal symptoms during mycophenolate sodium therapy. The secondary objective was to measure the mean daily mycophenolate sodium dose during routine therapy. These two parameters can significantly influence long-term graft survival of the patients. The study was a multicentric, non-interventional, 12 weeks, single arm, cohort, observational study, in which 251 adult, kidney transplant patients were enrolled in 4 study centers. As part of the study, the patient completed a questionnaire to assess the gastrointestinal status: the Gastrointestinal Symp­tom Rating Scale (GSRS). The patient’s average age was 51.03 years by the time of the inclusion. 61% of the patients were male and 39% female. Kidney transplant was performed averagely 6.3 years (SD: 4.3 years) prior to the screening visit. At the first visit the average intensity of gastrointestinal side effects was 0.87, at the final visit was 0.28. The change of the average number of gastrointestinal side effects between the first and last visit was examined by Wilcoxon test, and it was significant (p<0.0001). Patients had to complete the GSRS questionnaire aiming at five gastrointestinal symptom groups. In all five symp­tom-groups significant (p<0.0001) improvement was observed between the visits. Our results support that, in renal transplant patients with gastrointestinal undesirable effects due to MMF, using enteric-coated mycophenolate sodium may increase the maximum tolerated dose of MPA and reduce GI disorders.]

Mid-term oral isotretinoin therapy causes a predominantly sensory demyelinating neuropathy

ALTUN Yasar, INAN Esra

Aim - The purpose of this prospective study was to investigate whether mid-term treatment with oral isotretinoin may impact peripheral nerve function. Methods - In this study, we included 28 patients with no apparent neurological or neurophysiological findings. The patients received treatment with oral isotretinoin for papulopustular or nodulocystic acne. The patients with normal findings in the first examination were given 1 mg/kg/day oral isotretinoin. Neurological examinations and electroneurographic studies were performed before and 6 months after the onset of isotretinoin treatment. Results - Clinical examinations and electroneurographic evaluations prior to treatment revealed no abnormalities in any of the patients. However, 20 patients (72%) displayed one or more abnormal values in the tested parameters after treatment. Although the mean amplitudes of compound muscle action potential of the ulnar and median nerves did not vary, significant decreases were observed in the mean sensory conduction velocities of median, ulnar, sural, medial plantar, medial dorsal cutaneous, and dorsal sural nerves 6 months after the onset of treatment. Conclusion - Systemic use of isotretinoin may cause electroneurographic changes. Probable electroneurographic alterations may be detected at a much earlier period via dorsal sural nerve tracing when electrophysiological methods used in routine clinical practice cannot detect these changes.

[Perioperative management of patients with coronary stent undergoing noncardiac surgical procedures - Part II. - Algorythm of emergency and perioperative treatment decisions]

ZIMA Endre, MEZŐFI Miklós, BECKER Dávid, SZABÓ György, MERKELY Béla, PÉNZES István

[The aim of percutaneous coronary intervention (PCI) is to optimise coronary and cardial status, and thus improve short- and long-term outcomes. It is known from large Western databases that stent implantation is performed during 77-85% of coronary interventions, which means hundreds of thousands of patients with new stent every year. The majority of patients need to take dual platelet aggregation inhibitor, namely acetyilsalicylic acid and thienopyridin - most often clopidrogel - following stent implantation. It presents a major therapeutic dilemma when these patients need noncardiac surgery. First, the surgery should be performed with the least blood loss possible, which would be optimally achieved by suspension of the platelet aggregation inhibitor therapy that cannot be stopped during the critical period after stent implantation. Second, stent thrombosis should be avoided, which can only be achieved if platelet aggregation inhibitor therapy is continued. The aim of our paper is to summarise the current professional guidelines and the current risk estimation in the perioperative management of patients with coronary stent. In the second part of the article, we summarise the preoperative preparation of the patient, assessment of coronary status and cardial medication, and the optimal time and location of the surgery. We present the decision principles regarding the risks of perioperative bleeding and stent thrombosis, and the need to continue platelet aggregation inhibitor therapy.]

[Quantitative analysis of the genes determining spinal muscular atrophy]

NAGYMIHÁLY Mariann, HERCZEGFALVI Ágnes, TÍMÁR László, KARCAGI Veronika

[Spinal muscular atrophy (SMA) is one of the most common autosomal recessive diseases, affecting approximately one in 10.000 live births and with a carrier frequency of approximately one in 35. The disease is caused by a deficiency of the ubiquitous protein survival of motor neuron (SMN), which is encoded by the SMN1 and SMN2 genes. Due to a single nucleotide polymorphism in exon 7, SMN2 produces less full-length transcript than SMN1 and cannot prevent neuronal cell death at physiologic gene dosages. On the other hand, the copy number of SMN2 affects the amount of SMN protein produced and the severity of the SMA phenotype. SMN gene dosage analysis can determine the copy number of SMN1 to detect carriers and patients heterozygous for the absence of SMN1 exon 7. This study provides copy number estimation of SMN1 gene by real-time PCR technique in 56 SMA type I., II., III. patients, 159 parents and healthy relatives and in 152 undefined SMA patients. Among the family members, 91 carriers have been detected and in 56 patients homozygous deletion of SMN1 exon 7 has been confirmed. Moreover, in 12 patients compound heterozygosity of SMN1 exon 7 mutation has been detected, thus providing the possible diagnosis of SMA. In 94 patients, copy number of SMN2 has also been evaluated and a good correlation has been found with the phenotype of the disease. Due to the genetic complexity and the high carrier frequency, accurate risk assessment and genetic counselling are particularly important for the families. These new results provide improvement of the diagnostic service in SMA in Hungary with focus on proper genetic counselling and possible enrolment of the patients in future therapeutic interventions.]

[CARDIOVASCULAR PREVENTION OPPORTUNITIES OF RISK REDUCTION, 2010]

NAGY András Csaba

[10 years of experience following the millennium has confirmed again that data on long term cardiovascular morbidity and mortality can be influenced by effective prevention most substantially. Growing body of knowledge and experience in the field of modern cardiovascular prevention is available, but novel and novel milestone studies have been published leading to updating of guidelines, however, we cannot be satisfied with the results. Evidence suggest that despite recent efforts, Hungarian cardiovascular morbidity and mortality has not been reduced significantly and except for some success - acute ST elevation myocardial infarction care in accordance with the European standard - we are behind the other EU countries in cardiovascular mortality of the active (age 30-65 years) age group. Recently several interesting contradiction has been published in the field of prevention, like the effectiveness of aspirin as primer prevention, which changes our common prevention conception. Data have to be also addressed, which can explain the controversial results from a different point of view. Now we are talking about the results of REALITY study, which highlight not only the noncompliance of the patient but that of the physician as well.]
