[OUR EXPERIENCE WITH COMBINED ANTIVIRAL TREATMENT IN PATIENTS WITH CHRONIC HEPATITIS C WITH PERSISTENTLY NORMAL ALANINE AMINOTRANSFERASE LEVELS]

HORVÁTH Gábor, TOLVAJ Gyula, HALÁSZ Tünde, STOTZ Gyula

[INTRODUCTION - Persistently normal alanine aminotransferase levels, which occur in a fraction of patients chronically infected with hepatitis C virus, do not rule out the presence of chronic hepatitis C, even of that with advanced inflammation and fibrosis. Here we report our results of the treatment of these patients. PATIENTS AND METHODS - Patients with histologically confirmed chronic hepatitis C received combined antiviral treatment with pegylated interferon (alfa-2a 1×180 μg/week or alfa-2b 1×1.5 μg/kg/week) and ribavirin (800- 1200 mg/day) for 48-52 weeks. The alanineaminotransferase levels of 21 patients (14 females, 7 males, age: 20-54, mean 38 years) did not reach the upper limit of normal (40 U/l) during the period of observation (≥6 months). There were 19 and 2 cases with hepatitis C virus genotype 1b and 3, respectively. The patients' hepatitis activity index was 3.7 1.75, fibrosis score: 0.9 0.64, baseline viral titer: 1.18 1.12×106 IU/ml, alanine-aminotransferase level: 33.51 7.2 U/l. The last 100 unselected patients with elevated alanine-aminotransferase levels enrolled in treatment for chronic hepatitis C and who were followed for at least 6 months served as the control group with the following parameters: 41 females and 59 males (age: 18- 65, mean: 45.65 years), viral genotypes: 98 and 2 cases of type 1 and 3, respectively, hepatitis activity index: 5.44±4.03, stage: 1.29±1.00, baseline viral titer: 4.13±6.25×106 IU/ml. RESULTS - In the study group, all patients were hepatitis C virus RNA negative at the end of the treatment and with one exception remained so by the end of the 6-month follow-up period (20/21), while the sustained virologic response was 36% in the control group. The pretreatment normal alanine aminotransferase level decreased significantly (15.26 4.9 vs 33.51 7.2 U/l, p<0.001) by the end of the treatment, and remained at this level during the follow-up in all except one relapse case. CONCLUSION - The efficacy of the combined antiviral treatment is high in patients with persistently normal alanine aminotransferase levels, possibly due to the relatively younger age, the higher proportion of females, the lower baseline viral titer, and the less advanced liver disease (lower inflammatory activity and less or absent fibrosis) observed in this group. Combined antiviral treatment is recommended for patients with histologically confirmed chronic hepatitis C with normal alanine aminotransferase levels, even with mild inflammatory activity and minimal or absent fibrosis in the liver tissue. The previous suggestions based on published evidence to revise the upper limit of the normal range of alanine aminotransferase level are supported by the results of this study.]

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias

BALÁZS Nóra , BERECZKI Dániel, KOVÁCS Tibor

In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

[Vaccines against COVID-19 pandemic]

FALUS András, SZEKANECZ Zoltán

[The rapidly spreading SARS-CoV2 respiratory virus has evoked an epidemic with serious aftermath around the world. In addition to the health effects, the global economic damage is actually unpredictable. At the same time, the pandemic has launched a series of unprecedented collaborative scientific research, including the development of vaccines. This study summarizes up-to-date information on vaccines, immune memory, and some emerging clinical effects.]

[A short chronicle of three decades ]

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

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

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.
