[MOOT-COMP study - Compliance of patients with antiporotic treatment]

BORS Katalin, BOROS Erzsébet

[INTRODUCTION - Several studies prove the importance of the lack of compliance in the ineffectiveness of drugs which have been tested by clinical studies. In our study we finded the reasons of leaving off the antiporotic treatment. PATIENTS AND METHODS - 1067 osteoporotic patients (91% women, 9% men) were enrolled to examine compliance and to find explanation of non-compliance. We asked the patients about medications, exercises, electrotherapy and medical aids. RESULTS - Medications were recommended for most patients and exercise was the secondary most common therapeutic method. Electrotherapy was prescribed for one third and medical aids were recommended for one fifth of the recruited patients. Two third of patients reported to take all pills, most of them suffered from bone fracture. More than one fifth of patients sometimes or often forgot to take the treatment. 10% more patients did exercises than it was recommended by the practitioner. However, only 25% of all patients did exercises appropriate frequency and at least 20 minutes per day. Electrotherapy was not prescribed by the doctors for more than half of patients on this treatment. Medical aids were not used by 10% of patients despite the recommendations. Almost one third of the enrolled patients reported a fact which disturbed keeping recommendations of the doctors. These facts were financial problems, long waiting lists and low motivation of patients for keeping recommendations. The compliance did not correlate with education and social status. The patients with multiple fractures were more comply with medications and exercises. CONCLUSION - Drawing the informed patient into decision making and knowing the therapeutic outcome are important factors for keeping therapeutic recommendations. The high fracture rate in Hungary attracts our attention for enhance patient compliance.]

[Relationship of cardiovascular risk factors and bone status in a large adult population of the Balaton Region]

BUDAY BARBARA, IZSÓNÉ KATZ MELITTA, NAGY ELVIRA, PAPP ZSUZSA, KORÁNYI LÁSZLÓ

[BACKROUND - Numerous international studies have investigated the relationship between bone metabolism and type 2 diabetes mellitus. The results are controversial, there are those proving an increasing effect of diabetes on bone density but we know data that prove the opposite results. Our aim was to investigate the relationship between bone density, obesity and carbohydrate metabolism on a large Hungarian population. PATIENTS AND METHODS - The data from a large population screening (n=6287, mean age 56±13 years, men: n=1561, women: n=4726), carried out in the Balaton Region, Hungary, were analyzed (anthropometry, blood glucose and total cholesterol, blood pressure, calcaneus ultrasound T-score). RESULTS - Analyzing the relationship between type 2 diabetes and osteoporosis/osteopenia, we found, that the prevalence of osteopenia is significantly higher in diabetic women between 50-60 years of age than that of normal glucose tolerance, (50 vs. 36.34%, OR: 1.711, 95% CI: 1.076-2.722, p<0.022), however in different age groups and in males there were no significant differences, similar to the metabolic syndrome which did not influence the prevalence of osteoporosis/osteopenia. In normal weight (male and female) diabetic population over 60 years of age, the frequency of osteoporosis/ ostepenia was much higher, than in the normal weight normal glucose tolerance group, which difference was borderline-significant in the case of osteoporosis (63.63 vs. 26.2%, OR: 2.71, 95% CI: 0.969-7.6, p=0.054), and did not reach it with osteopenia (53.38 vs. 43.31%, p=0.359). In the same age group, within the “all glucose intolerant” and “all normal glucose tolerance” groups the prevalence of osteoporosis/osteopenia did not differ. We found significant correlation between BMI and T score only in women and it was strongest in age group of over 70 years (r=+0.23, p<0.001). CONCLUSION - Our data suggest that the increased bone density often measured in type 2 diabetic patients is actually the consequence of the accompanying obesity, and not of diabetes itself, which is rather a risk factor for bone loss.]

FERENCZ VIKTÓRIA, BOJSZKÓ ÁGNES, PALLINGER ÉVA, LAKATOS Péter, FALUS ANDRÁS, HORVÁTH CSABA

[INTRODUCTION - Histamine receptor antagonists seems to have effect on bone metabolism according to previous studies. We investigated the bone turnover in allergic children who were treated with H1-histaminreceptor (H1R) antagonists. PATIENTS AND METHODS - The biochemical bone turnover markers [β-CrossLaps (β-CTx), osteocalcin (OCN), β-CTx/OCN ratio], parathyroid hormone (PTH) and the 25(OH)vitamin D3 were determined in 37 H1Rantagonist treated multiplex allergic children and in 21 age and gender matched healthy children. The intracytoplasmatic histidine decarboxylase (HDC), histamin, and surface H1 and H2 receptors expression were assessed by flow cytometry on peripheral leukocytes. The distribution of lymphocyte subpopulation were also determined. RESULTS - The serum OCN, PTH and 25(OH)vitamin D3 levels did not differ between the healthy and the allergic groups. However, the β-CTx was lower in the H1Rantagonists treated allergic children (1090.82±80.25 pg/ml) in comparison with controls (1456.58±95.81 pg/ml; p=0.006). The β-CTx/OCN ratio was found to be lower in the H1R-antagonists treated allergic than in the controls (9.24±0.608 vs. 12.65±0.53; p=0.001). β-CTx serum level correlated with OCN in the controls (r=0.845, p<0.001) and in the H1R-antagonist treated allergic, too (r=0.519, p=0.005). Higher HDC expression and H1 receptor down regulation was found in allergic children. The CD3+/CD16-56+ T cells were in higher rate in children of control group. CONCLUSION - Decreased bone resorption was found among H1 receptor antagonist treated allergic children, which is indicated by serum markers. Therefore, bone turnover is shifted toward bone formation in the H1Rantagonist treated allergic subjects.]

Fluoxetine use is associated with improved survival of patients with COVID-19 pneumonia: A retrospective case-control study

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

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.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]
