[Systemic adjuvant pharmacotherapy of colorectal cancer]

BODOKY György

[Colorectal cancer is one of the most frequent cancer in the postindustrial world; its most common form is adenocarcinoma. In Hungary, colorectal cancer has the second highest mortality among tumours. If diagnosed early, it might be successfully treated by surgery, however, chemotherapy is necessary to prevent tumor relapse and development of metastases and achieve adequate palliation. In the past few years, adjuvant treatment of colorectal cancer has improved substantially. Many new drugs have been developed, which are also being used in combination with previously known agents. This article will discuss the novelties in the field of adjuvant chemotherapy for colorectal cancer and the main guidelines of adjuvant treatment.]

[Insulin analogues and pregnancy]

TAMÁS GYULA, KERÉNYI ZSUZSA

[Near-normoglycaemic metabolic control in pregnant women with diabetes - started before conception in pregestational diabetes - decreases the frequency of maternal and foetal complications. Such control can be achieved by using optimalised systems of insulin therapy. A number of (ultra)rapid and long-acting insulin analogues became available during the last decade, which - on the basis of theoretical considerations - might be used to maintain normoglycaemia. Summarising the data available today, the use of rapid insulin analogues (lispro, aspart) seem to be effective and safe during pregnancy. Some questions arise, however, about their modes of application. The use of long-acting insulin analogues in pregnancy is currently not indicated. Further trials are needed to prove their efficacy and safety in diabetic pregnancy.]

[Resistant hypertension - differential diagnosis and therapy]

TISLÉR András

[Hypertension is considered resistant to therapy if the target blood pressure is not achieved despite treatment with three different types of antihypertensive drugs, including a diuretic. Causes of therapy resistance may be grouped into three broad categories: Pseudoresistance can be the result of inadequate blood pressure measurement technique, the “white-coat” effect or the patients’ noncompliance with pharmacological and nonpharmacological medical advices. Evaluation of the measurement technique - including the size of the cuff used - and blood pressure monitoring at home can help identify the causes of pseudoresistance. Secondary resistance comprises drug interactions and concomitant medical conditions that elevate blood pressure or antagonize antihypertensive therapy. In addition, secondary resistance can result from disorders associated with secondary hypertension, among which appropriate screening for hyperaldosteronism as well as for renoparenchymal and renovascular hypertension need special emphasis. Suboptimal therapy is frequently related to subclinical volume overload and the use of inappropriate type or dosing of diuretics. Furthermore, when choosing the optimal drug combination, care should be taken to inhibit the various systems that regulate blood pressure as much as possible. In addition to combining the most frequently used antihypertensive drugs, the use of aldosterone antagonists, vasodilators, nitrates or drugs affecting the central nervous system might help to optimise treatment.]

[The relevancy of measuring the level of D-dimer test in clinical practice]

PINCZÉS István, SPEER Gábor

[Plasma levels of D-dimer may rise in a number of pathological conditions, which might be relevant for diagnosis as well as for prognosis. Its concentration increases with age, perhaps because of the wide-spread co-morbidity. In this article we demonstrate the diagnostic role of Ddimer in the well-known thromboembolic diseases. Beyond that, we highlight the importance of measuring D-dimer levels in other, lesser-known conditions, about which important findings have been published, such as cardiovascular, inflammatory or malignant diseases. It seems that in these disorders - provided that appropriate clinical conditions are available -, measuring D-dimer levels might have a role not only in diagnosis but in the prognosis as well. Furthermore, our aim was to discourage inappropriate clinical practice. Ignoring to measure the D-dimer levels (for fear of it being high) might lead to diagnostic errors. On the other hand, routinely performing the D-dimer test without clinical consideration (in the hope of it being negative) might cause diagnostic confusion in case of unexpected positivity and - mostly because of false interpretation - lead to further, unnecessary examinations.]

[Rituximab therapy in rheumatoid arthritis]

SÜTŐ Gábor

[Rheumatoid arthritis is a chronic, lifelong disease that causes severe joint deformity, reduces quality of life, and, if not treated appopriately, leads to disability and substantial premature mortality. Its treatment is a multistep procedure, where different grades of treatment options follow each other. Besides traditional, diseasemodifying antirheumatic drugs (DMARDs) and biological therapies inhibiting TNF, a new therapautic option is the use of a chimeric antibody, rituximab, which inhibits B lymphocyte function. This drug is an effective and safe choice for those patients who have received various anti- TNF therapies or do not tolerate TNF inhibition.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

[Christmas inventory]

BRYS Zoltán

[Overall, it is clear that humanity is facing perhaps its greatest challenge ever; humanity needs a consciously done reform, in its established economic and social mechanisms. A kind of passionate self-reflection, a dedogmatisation. This requires a deeper and more comprehensive understanding of its history and of itself. The way to a peaceful Christmas 2073, I suggest...]

A variant of Guillain-Barre syndrome after SARS-CoV-2 vaccination: AMSAN

TUTAR Kaya Nurhan, EYIGÜRBÜZ Tuğba, YILDIRIM Zerrin, KALE Nilufer

Introduction - Coronavirus disease 2019 (COVID-19) is a respiratory infection that has rapidly become a global pandemic and vaccines against SARS-CoV-2 have been developed with great success. In this article, we would like to present a patient who developed Guillain-Barré syndrome (GBS), which is a serious complication after receiving the inactive SARS-CoV-2 vaccine (CoronaVac). Case report – A 76-year-old male patient presented to the emergency department with nine days of progressive limb weakness. Two weeks prior to admission, he received the second dose of CoronaVac vaccine. Motor examination revealed decreased extremity strength with 3/5 in the lower extremities versus 4/5 in the upper extremities. Deep tendon reflexes were absent in all four extremities. Nerve conduction studies showed predominantly reduced amplitude in both motor and sensory nerves, consistent with AMSAN (acute motor and sensory axonal neuropathy). Conclusion - Clinicians should be aware of the neuro­logical complications or other side effects associated with COVID-19 vaccination so that early treatment can be an option.

Acute transverse myelitis after inactivated COVID-19 vaccine

ERDEM Şimşek Nazan, DEMIRCI Seden, ÖZEL Tuğba , MAMADOVA Khalida, KARAALI Kamil , ÇELIK Tuğba Havva , USLU Ilgen Ferda, ÖZKAYNAK Sibel Sehür

Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been rapidly developed to prevent coronavirus disease 2019 (COVID-19) pandemic. There is increasing safety concerns regarding COVID-19 vaccines. We report a 78-year old woman who was presented with tetraparesis, paresthesias of bilateral upper extremities, and urinary retention of one-day duration. Three weeks before these symptoms, she was vaccinated with CoronaVAC vaccine (Sinovac Life Sciences, China). Spine magnetic resonance imaging showed longitudinally extensive transverse myelitis (TM) from the C1 to the T3 spinal cord segment. An extensive diagnostic workup was performed to exclude other possible causes of TM. We suggest that longitudinally extensive TM may be associated with COVID-19 vaccination in this case. To the best of our knowledge, this is the first report of longitudinally extensive TM developing after CoronaVac vaccination. Clinicians should be aware of neurological symptoms after vaccination of COVID-19.

[Can we influence the negative drug attitude? Interpretation of the rejection of COVID-19 vaccine in the light of results of a pilot study ]

POGÁNY László , HORVÁTH A. András, LAZÁRY Judit

[Vaccination refusal is a serious obstacle to minimizing the spread of COVID-19. Nevertheless, the rejection of vaccine can be considered the result of a negative attitude towards medical treatment, and according to our previously published data, it can be influenced by the underlying affective state. Increased incidence of affective disorders and anxiety could be observed globally during the pandemic, which may have a significant impact on vaccination acceptance. The aim of our pilot study was to determine the association between clinical improvement of affective and neurocognitive symptoms and change of drug attitude and health control beliefs in a sample of psychiatric patients. A data set of 85 patients with psychiatric disorder has been analysed with the use of Patient’s Health Belief Questionnaire on Psychiatric Treatment (PHBQPT) with 5 subscales (Negative Aspect of Medication – NA; Positive Aspect of Medication – PA; Doctor health locus of control- Doctor HLOC; Internal HLOC; Psychological Reactance – PR); Hospital Anxiety Depression Scale (HADS-Anx; HADS-Dep) and neurocognitive tests, such as the Stroop test and the Trail Making Tests. All the tests were performed before and after a 14 days treatment. Paired t-tests and generalized linear models were performed to assess the associations between the variables. The baseline scores of NA and HADS-Anx correlated significantly (p=0.001) and after two weeks of treatment NA decreased (p=0.001), while Doctor HLOC and Internal HLOC increased (p=0.001 and p=0.006). The patients performance of the neurocognitive tests improved (all p<0.05). The reduction of HADS-Anx (p=0.002) and HADS-Dep (p=0.006) scores showed significant associations with the decrease of NA. Increase of the PA score was associated with reduction of HADS-Dep (p=0.028). Improvement of neurocognitive functions had no effect on PHBQPT scores. Important conclusions can be drawn regarding the rejection of the COVID-19 vaccine based on the associations found between the intensity of affective and anxiety symptoms and the attitude towards treatment. Our findings suggest that affective symptoms have a negative influence on the attitude towards treatment and that the improvement of these symptoms can facilitate the acceptance of the therapy, regardless of diagnosis. The modest effect of the improvement of neurocognitive functioning on the attitude towards drugs and the significant role of affective-emotional factors suggest that the accep­tance of vaccination probably cannot be facilitated solely with the aid of educational programs. Considering the increasing incidence of affective disorders during the COVID-19 pandemic, the screening of affective and anxiety symptoms and treatment of these disorders could be an important step towards the acceptance of the vaccine. Although psychiatry is not considered as a frontline care unit of the COVID cases, more attention is needed to pay on the availability of mental health services because refuse of vaccine can develop due to affective disorders too.]
