[Sarcopenia and quality of life: the validated Hungarian translation of the Sarcopenia Quality of Life (SarQoL) questionnaire]. / Sarcopenia és életminoség: a Sarcopenia Quality of Life (SarQoL) kérdoív hiteles magyar fordítása.

INTRODUCTION: Sarcopenia, or age-related muscle loss, is emerging as a serious public health concern. Due to the impaired physical performance associated with sarcopenia, a reduced quality of life (QoL) has been evidenced in the affected individuals. Generic instruments, such as Rand Corporation Short Form 36 (SF-36) or the European Quality of Life (EuroQoL-5D) questionnaires do not accurately assess the impact of sarcopenia on QoL. SarQoL (Sarcopenia Quality of Life) questionnaire, was the first disease-specific questionnaire addressing the quality of life in patients with sarcopenia and has been recently designed for providing a global assessment of the quality of life in community-dwelling elderly subjects aged 65 years and older. AIM: Our aim was the development of a valid Hungarian version of the original SarQoL, through the translation, cultural adaptation and content validation of the original questionnaire. METHOD: We followed the recommended process, the international protocol of translation in five steps: two initial translations, synthesis of the two translations, backward translation, expert committee to compare translations with the original questionnaire and pretest. The pretest process involved 20 subjects (10 clinically sarcopenic and 10 non-sarcopenic with different educational and socioeconomic backgrounds) who were asked to complete the questionnaire. Feedbacks were requested from all subjects regarding the comprehensibility of questions or difficulties in completing the test. RESULTS: Using the recommended best practice protocol for translation, the pre-final version is comparable with the original instrument in terms of content and accuracy. CONCLUSION: After the content validation with clinically sarcopenic persons it should be a useful tool to assess the quality of life of people with sarcopenia among elderly Hungarian patients.

[Peroral and transdermal application of non-steroidal anti-inflammatory drugs (NSAIDs) for the treatment of regional musculoskeletal pain syndromes]. / Nem szteroid gyulladáscsökkentok peroralis és transdermalis alkalmazása regionális mozgásszervi fájdalmi szindrómákban.

In this review the available evidences regarding the most frequently applied medication (peroral and transdermal non-steroidal anti-inflammatory agents) for the most frequent musculoskeletal complaints (regional pain syndromes) have been collected for the appropriate medical professionals who are most frequently faced with these conditions (general practitioners, rheumatologists, orthopedics, occupational and sports medicine experts). The special population at risk (with repeated and high energy overuse because of occupational or sport activities) and the pathology of their syndromes are identified. Mode of action, pharmacological properties of the non-steroidal anti-inflammatory drugs and the unwanted effects of their application especially in infants and elderly are highlighted. Recommendations of the general and specific pain management guidelines have been selected and listed in the review. Orv Hetil. 2017; 158(Suppl. 3): 3-30.

Psychosocial, educational, and somatic factors in chronic nonspecific low back pain.

Analysis of the effect of psychosocial factors and co-morbidities on the health status of patients with chronic nonspecific low back pain and patients with surgical intervention because of disk herniation was performed. One hundred and two nonselected consecutive inpatients with chronic nonspecific low back pain were included in the study. Their average age was 56.7 (SD = 10.9) years. The control group consisted of 199 subjects matched according to age and sex, chosen from the database of the national representative health survey Hungarostudy 2006, which involved 4,527 subjects. We measured quality of life including mental health with the SF-36 questionnaire validated for use in Hungary, the short 9-item version of the Beck Depression Inventory, the WHO-Five Well-Being Index, and the Hospital Anxiety-Depression Scale. We characterized the socio-demographic status with variables on age, sex, marital status, and education. Data on symptoms and signs of low back pain, other musculoskeletal diseases, and their treatments including spinal surgery were recorded. Co-morbidity and body mass index were considered as independent indicators of health. Depression as measured by Beck Depression Inventory and severity of depression did not vary significantly according to marital status, education, hypertension, diabetes, and gastrointestinal disease. Only half of the patients (52 %) were in the normal range of the scale; 22 % suffered from mild, 16 % from moderate, and 12 % from severe depression. Average values for anxiety and depression as measured by Hospital Anxiety-Depression Scale and Beck Depression Inventory were both significantly higher in the patient than in the control group (Hospital Anxiety Scale: p = 0.0001; Beck Depression Inventory: p = 0.0001). According to the WHO Well-Being Index-5 scale, the difference between patients and the control group was significant (p = 0.0001). Furthermore, correlation was found between the incidence of depression and surgery. Depression was demonstrated in 47.4 % of those patients who had no surgery, in 50 % of patients who had one round of surgery, and in 62.5 % of those who had undergone surgery more than once; the contingence coefficient was 0.211. According to different measurements, the psychological state of patients with chronic nonspecific low back pain was significantly altered as compared to the matched Hungarian population. Higher anxiety and depression markers occurred in 48 % of the patients. There was no correlation between the depression of patients with low back pain and variables such as marital status, education, and co-morbidities. Our study is the first to demonstrate that depression runs parallel with the number of surgical procedures. Therefore, if there is a relative indication for surgery, depression and severity of depression should be assessed and considered when deciding on the intervention.

Back pain and sacroiliitis in long-standing adult celiac disease: a cross-sectional and follow-up study.

There have been only scattered reports suggesting that musculoskeletal manifestations including back pain and sacroiliac joint involvement may be associated with celiac disease. In order to confirm this issue in a larger cohort, rheumatic manifestations were analyzed in 21 adult celiac patients using a comprehensive clinical, laboratory and radiological analysis. The diagnosis of celiac disease was based on the histopathology of jejunal biopsy specimens. The mean duration of celiac disease was 15 (0-31) years. All patients were currently on gluten-free diet and none of the patients had gastrointestinal symptoms at the time of the study. Using various imaging techniques, involvement of the sacroiliac joints was confirmed in 70% of celiac patients. Imaging revealed different morphological changes in the sacroiliac joint, e.g. accumulation of synovial fluid, synovitis, erosion with concomitant sclerosis, sacroiliitis or calcification of the ligament. These changes probably represent different clinical stages and/or manifestations of the same process. In a follow-up study of eight patients, after 11 years on a gluten-free diet, the great majority of patients had no clinical symptoms; yet, a subclinical progression of the sacroiliac joint involvement could be verified. Our results suggest the importance of regular rheumatologic follow-up of patients with celiac disease.

[Genetic and immunological processes in the pathomechanism of gluten-sensitive enteropathy and associated metabolic bone disorders]. / Genetikai és immunológiai tényezok a gluténszenzitív enteropathia és az asszociált csontmetabolikus eltérések patogenezisében.

Celiac disease or gluten-sensitive enteropathy is the most common disease of jejunum, leading to malabsorption. It is an immune mediated disease induced by gluten at the presence of genetic predisposition. After gluten exposition, immune processes are induced by T-cell mediation causing typical intestinal and extra intestinal manifestations. The diagnosis of celiac disease is still set up on the result of jejunal biopsy and detecting of antibodies against endomysium and tissue transglutaminase. From genetic aspect, association with HLA DQ2/DQ8 is identified in celiac disease. On a strict gluten-free diet, the clinical, histological and serological results improve and remission of accompanying diseases may be achieved. In the etiopathogenesis of celiac disease several genetic and immunological mechanisms have been recognized in recent years. Connected to the accompanying diseases, more reviews have been issued about the bone metabolic changes and less about the inflammatory join disorders. In the present work, the authors review literature data that reveal common background from both immunological and genetic aspects.

INTRODUCTION: Sarcopenia is an age-related involution process, causing a significant functional disability, therefore it can be classified as a disease. Early recognition of the disease is essential. Objetive: Authors of the original SARC-F questionnaire developed a simple and rapid screening tool, recommended by the European Working Group on Sarcopenia as the mandatory first step in the diagnostic process of sarcopenia. Our study aimed to test and validate the Hungarian version of this instrument. METHOD: 105 volunteers of 65+ years were recruited and evaluated for sarcopenia (muscle mass, strength and performance). Participants completed the SARC-F, other two generic and one disease-specific quality-of-life questionnaires. We checked the instrument for reliability, validity (discriminative power, construct, convergent and divergent validity) and screening performance. STATISTICAL ANALYSIS: Cronbach's alpha test, the Pearson/Spearman's correlation coefficient, chi-square test, sensitivity, specificity, positive and negative predictive value calculations have been performed. The SPSS 17.0 statistical program was used. RESULTS: The prevalence of sarcopenia according to the SARC-F test (score: ≥4) was 36%, while 40% was diagnosed with the European consensus definition. Sarcopenic individuals had significantly higher SARC-F total and domain scores. Very good internal consistency (Cronbach's alpha 0.755), specificity and negative predictive values were found. CONCLUSION: A reliable, rapid and inexpensive sarcopenia indicator is now available to timely detect the Hungarian-speaking patients at risk of sarcopenia. Orv Hetil. 2020; 161(47): 2000-2005.

Brief Report: Safety and Immunogenicity of Rituximab Biosimilar GP 2013 After Switch From Reference Rituximab in Patients With Active Rheumatoid Arthritis.

OBJECTIVE: Comparable clinical efficacy of the rituximab (RTX) biosimilar GP2013 and reference RTX has been established in blinded randomized trials. However, when switching from a reference biologic to a biosimilar, potential safety implications are often an important consideration. Therefore, the aim of this study was to evaluate the safety of switching from reference RTX to RTX biosimilar GP2013 compared with treatment continuation with reference RTX in patients with rheumatoid arthritis (RA). METHODS: In this multinational, randomized, double-blind, parallel-group safety study, 107 patients with RA who had previously received treatment (of any duration) with reference RTX as part of routine practice and who required continuation of treatment were randomized to receive either GP2013 or to continue treatment with reference RTX. All patients received a stable dosage of methotrexate and folic acid during the study. Study assessments included the incidence of hypersensitivity, infusion-related and anaphylactic reactions, immunogenicity (antidrug antibodies), and general safety. RESULTS: Regardless of whether patients switched to GP2013 or continued treatment with reference RTX, the incidences of hypersensitivity (9.4% and 11.1%, respectively) and infusion-related reactions (11.3% and 18.5%, respectively) were similarly low. Only 1 patient (in the reference RTX group) developed antidrug antibodies to RTX after starting study treatment. No neutralizing antidrug antibodies were observed. Antidrug antibodies were not associated with adverse events (AEs). No clinically meaningful differences in the rate of AEs were observed between treatment groups. CONCLUSION: No safety risks were detected when patients switched from reference RTX to GP2013. The safety profiles of patients in both treatment groups were similar, although the study was not powered for statistical testing of equivalence in safety.

Fatal idiopathic pulmonary haemosiderosis in association with pregnancy - medico-legal evaluation.

Idiopathic pulmonary haemosiderosis is a rare disorder characterised by repeated episodes of intra-alveolar bleeding in association with consecutive anaemia, pulmonary fibrosis, pulmonary hypertension and respiratory failure. Pregnancy may exacerbate the symptoms of idiopathic pulmonary haemosiderosis typically worsening in the third trimester. A 32-year-old female after delivery was admitted to hospital with progressive dyspnoea of about 1-month duration. Sudden circulatory collapse caused fatal complication. During the post-mortem investigation, lung haemorrhage and histologically abundant iron deposition in macrophages and interstitial fibrosis were found. Medico-legal post-mortem evaluation of fatal cases may support the clinico-pathological context of the diagnosis of this entity.

Genetic and immunological processes in the pathomechanism of gluten-sensitive enteropathy and associated metabolic bone disorders.

Celiac disease, or gluten sensitive enteropathy is a relatively common disease of the jejunum, leading to malabsorption. It is an immune mediated disease, induced by gluten on the grounds of a specific genetic makeup. After gluten exposition immune processes are induced mainly by T-cells, causing typical intestinal and extra intestinal manifestations. The diagnosis of celiac disease is based on jejunal biopsy histology and the presence of antibodies against endomysium and tissue transglutaminase. Genetically, celiac disease is associated with HLA DQ2/DQ8. Strict gluten-free diet improves the clinical, histological and serological picture and remission may be achieved. In the etiopathogenesis of celiac disease several genetic and immunological mechanisms have been recognized in the recent years. Concerning accompanying diseases/extraintestinal manifestations, several disorders have been shown, including rheumatological diseases. In celiac disease, bone metabolic changes are more frequent compared to the prevalence of inflammatory join disorders. In this review, we aim to give an overview on various aspects of the genetic and immunological processes in the pathomechanism of gluten-sensitive enteropathy and associated metabolic bone disorders.
