Antiviral Therapy of Chronic Hepatitis B Virus between Present and Future

Background/Objectives: The objective of this study was to analyze the results of clinical trials regarding long-term antiviral therapies in chronic hepatitis with HBV to compare current therapeutic protocols and to analyze the results of preliminary studies with new antiviral therapies for HBV. Methods: Clinical studies and meta-analyses from PubMed, Google Scholar, and Research Gate from 2011 to 2024 were analyzed on patients undergoing chronic antiviral therapy for HBV, and a retrospective observational study performed in our clinic on a group of 76 patients undergoing chronic therapy with entecavir was presented. Also, a summary of the results of preliminary studies with various innovative antiviral molecules for HBV was performed. Results: The results of extensive clinical trials reveal that current therapies for chronic HBV are well tolerated and maintain good viral suppression if the patient is adherent to therapy. Innovative therapies aim to eliminate HBsAg and, thus, significantly shorten the duration of treatment, and the preliminary results of the studies are promising. Conclusions: Being an asymptomatic condition that requires life-long therapy, adherence to therapy is a real problem. Also, the risk of decompensation of liver cirrhosis and adenocarcinoma remains important in these patients. Future research is needed to perfect some antiviral therapy schemes that shorten the treatment period but also decrease the rate of progression towards decompensated cirrhosis and liver adenocarcinoma.

Non-operative Management - The First Option in the Treatment of Blunt Liver and Spleen Trauma in Pediatric Patients

AIM

The aim of the present study is to assess some characteristics of blunt hepatic and splenic injuries in children, the non-operative management (NOM) procedures and efficiency, over a 5-year period in a tertiary hospital for children. Materials and Methods: We conducted a retrospective study on 32 patients with blunt liver and/or spleen injuries. Age, gender, mechanism of injury, hemoglobin and hematocrit levels, lenght of stay and bedrest, imaging diagnosis, hemostatics and transfusions, treatment, and discharge status were evaluated. Results: 58% of patients were males. Mean age was 10.7 years. The main mechanism of injury was motor vehicle accident. Ultrasound (US) and Computed Tomography (CT) found 56.2% patients with spleen injury and 43.8% with liver injuries. On US the most frequent injuries were lacerations, and on CT were splenic-grade III and hepatic-grade II. 84.4% of patients were hospitalized in Intensive Care Unit and 15.6% in the surgical unit. The mean hemoglobin and hematocrit were 10.91g/l and 33%, respectively.The treatment was non-operative for 84.4%, and operative for 15.6%. When discharged, 56.2% of patients were cured and 43.8% were improved.

CONCLUSION

With a performing multidisciplinary team of surgeons, intensive care therapists and radiologists, NOM in pediatric patients with blunt liver and spleen injuries is safe and effective, may be conducted depending on the hemodynamic stability rather than the lesions' extension, and reduces the ICU lenght of stay, as well as the need for hemostatics and transfusion.

Efficiency of continuous positive airway pressure and high-flow nasal oxygen therapy in critically ill patients with COVID-19

OBJECTIVE

Critically ill patients with COVID-19 develop acute respiratory distress syndrome characterized by relatively well-preserved pulmonary compliance but severe hypoxemia. The challenge in managing such patients lies in optimizing oxygenation, which can be achieved through either high oxygen flow or noninvasive mechanical ventilation. This study was performed to compare the efficiency of two methods of noninvasive oxygen therapy: continuous positive airway pressure (CPAP) and high-flow nasal oxygen therapy (HFNO).

METHODS

This retrospective cohort study involved 668 patients hospitalized in the intensive care unit (ICU) of the "Sf. Apostol Andrei" Emergency Clinical Hospital, Galati, Romania from 1 April 2020 to 31 March 2021 (CPAP, n = 108; HFNO, n = 108).

RESULTS

Mortality was significantly lower in the CPAP and HFNO groups than in the group of patients who underwent intubation and mechanical ventilation after ICU admission. Mortality in the ICU was not significantly different between the CPAP and HFNO groups.

CONCLUSIONS

HFNO and CPAP represent efficient alternative therapies for patients with severe COVID-19 whose respiratory treatment has failed. Studies involving larger groups of patients are necessary to establish a personalized, more complex management modality for critically ill patients with COVID-19.

Sleep Disorders Associated with Neurodegenerative Diseases

Sleep disturbances are common in various neurological pathologies, including amyotrophic lateral sclerosis (ALS), multiple system atrophy (MSA), hereditary ataxias, Huntington's disease (HD), progressive supranuclear palsy (PSP), and dementia with Lewy bodies (DLB). This article reviews the prevalence and characteristics of sleep disorders in these conditions, highlighting their impact on patients' quality of life and disease progression. Sleep-related breathing disorders, insomnia, restless legs syndrome (RLS), periodic limb movement syndrome (PLMS), and rapid eye movement sleep behavior disorder (RBD) are among the common sleep disturbances reported. Both pharmacological and non-pharmacological interventions play crucial roles in managing sleep disturbances and enhancing overall patient care.

Calcium, Phosphorus and Magnesium Abnormalities Associated with COVID-19 Infection, and Beyond

The coronavirus disease (COVID-19) pandemic caused by the novel coronavirus SARS-CoV-2 has had a profound impact on global health, leading to a surge in research to better understand the pathophysiology of the disease. Among the various aspects under investigation, disruptions in mineral homeostasis have emerged as a critical area of interest. This review aims to provide an overview of the current evidence linking calcium, phosphorus and magnesium abnormalities with COVID-19 infection and explores the potential implications beyond the acute phase of the disease. Beyond the acute phase of COVID-19, evidence suggests a potential impact of these mineral abnormalities on long-term health outcomes. Persistent alterations in calcium, phosphorus and magnesium levels have been linked to increased cardiovascular risk, skeletal complications and metabolic disorders, warranting continuous monitoring and management in post-COVID-19 patients.

Comparative Evaluation of the Clinical Severity of COVID-19 of Vaccinated and Unvaccinated Patients in Southeastern Romania in the First 6 Months of 2022, during the Omicron Wave

(1) Background: The pandemic wave produced by SARS-CoV-2 Omicron was characterized by milder clinical forms and high contagiousness. The vaccination rate against COVID-19 in Romania was approximately 42%. (2) Objectives: Comparison of the clinical severity in vaccinated patients compared to unvaccinated ones. (3) Methods: A retrospective cohort study was conducted on a group of 699 adult patients confirmed with COVID-19 who presented in the "Sf. Cuvioasa Parascheva" Infectious Diseases Clinical Hospital of Galati, Romania, between 1 January 2022 and 30 June 2022. The study compared the need for hospitalization, reinfections, demographic and comorbidity data, clinical and paraclinical parameters from the initial evaluation, and the ratio of unfavorable developments on subgroups chosen according to the vaccination status. (4) Results and Conclusions: Our study reveals that unvaccinated patients required hospitalization in 54.68% of cases, while fully vaccinated patients had a hospitalization rate of 40.72%, which was significantly lower than that of the unvaccinated group (p = 0.01); patients who received a booster dose had a hospitalization rate of 27.84% (p < 0.01, significantly lower than unvaccinated individuals; p = 0.01, significantly lower than fully vaccinated individuals); and among the four patients who received four doses, none required hospitalization. From the analysis of the two subgroups of hospitalized patients, we observed a significantly higher prevalence of radiological lesions, such as pulmonary opacities in the group of unvaccinated patients and a higher average duration of hospitalization, and serum values of D-dimers and blood-sugar at admission were significantly higher in unvaccinated patients. The higher presence of these parameters, which are indicators of severe progression in clinical studies, in the group of unvaccinated patients suggests the need to include them in the initial evaluation of the unvaccinated patients with COVID-19.The cumulative share of deaths and transfers in the ICU was higher in the group of unvaccinated patients, but the difference between the groups had no statistical significance. This study draws attention to the possibility of severe clinical forms among both vaccinated and unvaccinated populations, especially in the elderly and in patients with multiple comorbidities.

Changes in Dento-Facial Morphology Induced by Wind Instruments, in Professional Musicians and Physical Exercises That Can Prevent or Improve Them-A Systematic Review

The aim of this study is to highlight the changes that occur regarding dento-facial morphology, facial, and masticatory muscles in musicians who play wind instruments. Anatomical and functional changes may occur after the long-term use of each type of wind instrument. We considered studies of the impact of playing the wind instrument on the masticatory muscle activity and the resulting modifications. Both children and adults can be affected by playing wind instruments in regard to tooth positioning and facial morphology. These changes relate to the type of wind instruments, the type of vowels and tones used by instrumentalists. There most valuable breathing techniques have been identified that improve the redistribution of pressure, with a minimizing effect on the morphological changes in the oral cavity and cephalic extremity, implicitly on the masticatory functional disorders. In addition to these beneficial effects on the stomatognathic system, these breathing techniques favorably increase lung capacity. Furthermore, a series of toning exercises for neck muscles-which are actively involved and overworked by wind instrument-playing artists-was identified. The study concludes that less experienced instrumentalists demonstrate increased facial muscle engagement, possibly leading to excessive strain, while experienced instrumentalists exhibit more optimized patterns of muscle activity. The novelty of this research lies in its interdisciplinary approach to understanding the influence of wind instruments on dento-facial morphology, addressing preventive and corrective measures to mitigate undesirable outcomes.

Giant Benign Struma Ovarii with High-Grade Fever, Elevated CA 125, and Hormonal Function in an Adolescent Patient

Struma ovarii (SO) is a monodermal teratoma containing at least 50% thyroid tissue. Classically, SO is a hormonally inactive benign neoplasm that occurs in premenopausal women, and has unspecific clinical and imaging features. Its treatment is surgical and its diagnosis is established histopathologically. We report the case of a euthyroid 16-year-old girl presenting with abdominal girth increase. An abdomino-pelvic ultrasound showed a giant multicystic mass with transonic content and multiple septa, and magnetic resonance imaging suggested the diagnosis of right ovarian mucinous cystadenoma. Blood tests showed inflammatory syndrome, iron deficiency anemia, mild hepatocytolysis, and elevated serum CA 125 levels. High-grade fever occurred on the third day of hospitalization, but none of the preoperative tests could identify its origin. Cystectomy was performed, and the histopathological examination revealed benign SO with a few small cysts with purulent content. The patient developed hypothyroidism postoperatively. In conclusion, this case report reunites most of the uncommon features of SO and confirms the superiorityof histopathology in its definitive diagnosis, as well as the suitability of ovarian sparing techniques, as the best treatment option for cystic ovarian pathology in pediatric patients, even in cases of large tumoral size and elevated serum CA 125 levels.

Ag-Decorated Iron Oxides-Silica Magnetic Nanocomposites with Antimicrobial and Photocatalytic Activity

Nanotechnology offers unlimited possibilities for creating effective hybrid materials, which combine functional performance in environment depollution and antimicrobial defense with a lack of toxicity, biocompatibility, biodegradability, and natural availability. This paper presents the silver effect on photocatalytic and antibacterial activities of double-coated iron oxide nanoparticles (NPs), Fe3O4@SiO2/ZnO-Ag. The structural, morphological, and textural information of the, core-shell iron oxides-based superparamagnetic nanoparticles (IOMNPs) decorated with 5% Ag by ultrasound-assisted synthesis were evaluated by scanning electron microscopy with energy dispersive spectroscopy (SEM-EDX), X-ray diffraction, Raman spectroscopy, and Brunauer-Emmett-Teller physisorption measurements. Although two synthesis temperatures of 95 and 80 °C were used for the co-precipitated iron oxide cores, the XRD patterns revealed the formation of a single magnetite, Fe3O4, phase. The sorption-photocatalytic activities under dark and UV irradiation encountered a maximum removal efficiency of the MB (90.47%) for the Fe3O4@SiO2/ZnO-Ag sample with iron oxide core obtained at 80 °C. The rate constant for the second-order kinetics was 0.0711 min-1 for 2 h, and the correlation coefficient R2 closed to unity. Two samples with Ag-decorated hybrid SiO2/ZnO shell and hierarchically interconnected porous structure with large surface area (328.8 and 342.5 m2g-1) exhibited the best disk diffusion antimicrobial activity against four microorganisms, especially gram-positive Staphylococcus aureus.

Clinical, Imaging, Histological and Surgical Aspects Regarding Giant Paraovarian Cysts: A Systematic Review

Paraovarian cysts (POCs) develop within the broad ligament of the uterus. POCs are considered to be giant when the threshold of 150 mm is exceeded. Clinical signs and symptoms occur as a consequence of the pressure effect on adjacent organs or due to complications. Abdominal ultrasonography, computed tomography or magnetic resonance imaging are useful imaging tools, but most often the exact origin of such voluminous cysts is revealed only by surgical exploration. The review aims to appraise and update the diagnostic, the histological aspects and the treatment of the giant POCs in rare cases. We carried out a systematic search in Medline-PubMed, Google Scholar and ResearchGate electronic databases. Twenty-seven papers fulfilling the selection criteria were included in the review. The data extracted included information about first author, year of publication, country, patient age, size and side of the POCs, symptoms, tumoral markers, imaging methods, preoperative diagnosis, surgical management and histopathological findings. Although not very numerous, all the studies highlighted the low incidence of giant POCs, the impossibility of establishing the origin of the cystic mass by clinical and imaging methods even with advanced technical tools and the low risk of torsion (11.1%). Despite the recognized benign nature of POCs, we found an unexpected high percent (25.9%) of borderline giant POCs. Surgical excision is the only treatment option. Ovarian-sparing surgery was performed in 85.1% of the cases, and minimally invasive techniques were applied in only 42.9% of the patients, which demonstrates the need of a high-level laparoscopic expertise. Knowledge of this pathology, its recognition as a possible etiology of an abdominopelvic cyst, and a higher awareness of the possibility of a borderline histology in giant POCs are required for the proper management of these particular cases.

Risk of hepatitis B reactivation: From biologic therapies for psoriasis to immunosuppressive therapies for COVID‑19 (Review)

The cytokine storm from the evolution of severe cases of COVID-19, requiring strong immunosuppressive therapies, has raised the issue of reactivation of hepatitis B virus (HBV) infections in these patients. An analysis of the first observational studies in patients with COVID-19 and immunosuppressive therapy and HBV infection along with special clinical cases was presented, as well as personal experience on a series of cases (a group of 958 patients with COVID-19), compared with the analysis of studies performed on patients with HBV infection that underwent biological therapies for psoriasis and personal experience (a group of 81 psoriasis patients treated with biological therapies). Clinical studies have revealed that HBV reactivation in patients undergoing biological therapies for psoriasis, can be prevented with monitoring and treatment protocols and thus, these therapies have been demonstrated to be safe and effective. In COVID-19, immunosuppressive therapies are short-lived but in high doses, and the conclusions of clinical trials are contradictory, but there are published cases of HBV reactivation, which requires a unitary attitude in the prevention of HBV reactivation in these patients. An algorithm was presented for monitoring and treatment of HBV infection for patients with psoriasis treated with biological therapy and the conditions when this protocol can be used for patients with COVID-19 and immunosuppressive therapy.

The Role of D-Dimers in the Initial Evaluation of COVID-19

Purpose

The COVID-19 pandemic was noted for the high degree of contagion and the large number of cases, as well as for the various clinical forms, from asymptomatic towards rapid evolution to death. The hospitals limited care capacity imposed the need to identify some markers of unfavorable evolution. The purpose of our study is to identify the parameters correlated with COVID-19 unfavorable evolution and to draw the profile of the patient at risk of unfavorable evolution. This set of parameters will help the doctor in deciding whether to hospitalize a patient and in choosing the treatment.

Patients and Methods

We performed a prospective, observational, actively controlled study on 849 patients with COVID-19, hospitalized in the Second Clinic of “Sf. Cuv. Parascheva” Infectious Diseases Clinical Hospital Galati, Romania, between 1.03.2020–30.11.2020.

Results

The parameters statistically significant modified at the admission of the patients with COVID-19 unfavorable evolution were age, oxygen saturation, D-dimers, creatine kinase (CK), troponin, erythrocytes sedimentation rate (ESR), leukocytes, lymphocytes, neutrophils, platelets, hemoglobin (Hb), aspartate transaminase (AST), total and direct bilirubin (TBIL, DBIL), urea, creatinine, serum glucose. Strong correlations were observed between the unfavorable evolution and the admission values of D-dimers, AST, TBIL and between D-dimers and AST, which suggests that D-dimers levels can be considered predictive for the alteration of liver function and for the negative prognosis of the patient.

Conclusion

Coagulation disorders and acute respiratory failure are the prevailing causes of death from COVID-19. Together with other parameters that constitute the risk profile for severe COVID-19 evolution, the D-dimers dosing at admission proved to be extremely useful in the management of COVID-19.

Benefits and adverse events of melatonin use in the elderly (Review)

Melatonin is a hormone secreted by the pineal gland in accordance with the circadian rhythm when the light level decreases. Reduction of melatonin secretion with age may be associated with physiological aging in neurodegenerative diseases by affecting the suprachiasmatic nucleus or of the neuronal pathways of transmission to the pineal gland. A significant decrease in melatonin synthesis has been reported in various disorders and diseases, including cardiovascular diseases, metabolic disorders (particularly diabetes type 2), cancer and endocrine diseases. In addition to the fact, that melatonin is a sleep inducer, it also exerts cytoprotective properties as an antioxidant and free radical scavenger. The therapeutic role of melatonin has been demonstrated in sleep disorders, eye damage and cardiovascular disease. The association between melatonin and β-blockers has had a positive impact on sleep disorders in clinical trials. Previous studies have reported the anti-inflammatory effect of melatonin by adjusting levels of pro-inflammatory cytokines, including interleukin (IL)-6, IL-1β and tumor necrosis factor-α. Melatonin treatment has been demonstrated to decrease IL-6 and IL-10 expression levels and efficiently attenuate T-cell proliferation. Currently, there is an inconsistency of scientific data regarding the lowest optimal dose and safety of melatonin for long-term use. The aim of the present review was to summarize the evidence on the role of melatonin in various clinical conditions and highlight the future research in this area.

Orthopaedic manifestations of neurofibromatosis type 1: A case report

Neurofibromatosis type 1 (NF1) or von Recklinghausen disease is one of the most common autosomal dominant genetic diseases. It is characterized by ‘café-au-lait’ spots and multiple tumors starting from the central and peripheric nervous system. The diagnosis is determined on two out of seven criteria: i) A total of 6 or more light brown spots larger than 5 mm in diameter (pre-puberty) or 15 mm in diameter (post-puberty); ii) a total of 2 or more neurofibromas or one plexiform neurofibroma; iii) axillary or inguinal freckling; iv) optic glioma; v) a total of 2 or more Lisch nodules; vi) bone abnormalities: tibia pseudarthrosis or dysplasia of the sphenoid wing; and vii) a relative of first degree having an NF1 diagnosis. A total of ~50% of patients have significant musculoskeletal manifestation, with scoliosis and congenital pseudarthrosis of tibia most common. Management of the orthopaedic manifestations of NF1 is often difficult. Due to NF1 influencing multiple organ systems, patients are likely to benefit most from a multidisciplinary treatment strategy.

Diagnostic and Management of Undescended Ovary - A Preoperative Dilemma: A Case-Based Systematic Review

Undescended ovary (UO) is an uncommon congenital condition characterized by the presence of the adnexa above the common iliac vessels, with an estimated incidence of 0.3–2%. Because of its rarity, it is usually presented as a case report. A thorough knowledge of the ovarian embryological development is essential for the clinician, who must be warned about the possibility of associated Müllerian and renal malformations. There may be asymptomatic patients, incidentally diagnosed during infertility evaluation, but when symptoms occur, these are unspecific and most often this disorder is misdiagnosed, the accurate diagnosis being established intraoperatory. The malignant potential of an UO is accepted, although no such cases were reported. The role of the UO in infertility is still unclear, despite evidence of its normal function. Complications are linked to the ovary (cyst formation, cyst ruptures or tumors) or to the undescended fallopian tube (ectopic pregnancies). The management should be conservative, but there is no consensus about whether it is necessary to excise the ipsilateral undescended tube. We included a short case presentation of an UO cystadenoma misdiagnosed as a renal cyst, which depicts all diagnostic and management dilemmas and inspired us to write this review. The present literature review includes all the cases reported from the early 20th century to the present, with updated data about epidemiology, pathophysiology, clinical and imaging diagnosis, treatment options and prognosis of this rare condition. This paper aims to establish some directions in the diagnosis and management of similar patients and to remind us that, no matter how advanced the imaging investigation techniques might be, a correct preoperative diagnosis may often be missed.

COVID-19 impact on the liver

The coronavirus disease 2019 (COVID-19) pandemic imposed arestructuring of global health systems by rethinking spaces used for the care of these patients and the additions of intensive care, infectious diseases and pneumology departments. This paper provides evidence on the presence of severe acute respiratory syndrome coronavirus 2 in hepatocytes and its direct cytopathic activity, as well as the degree of liver damage due to drug toxicity, inflammation and hypoxia in COVID-19. A review of clinical trials has quantified liver damage through both pathology and biochemistry studies. Additionally, we briefly present the results of a study conducted in our clinic on 849 patients admitted for COVID-19 treatment, of which 31 patients had pre-existing chronic liver disease and 388 patients had values above the normal limit for alanine aminotransferase, aspartate aminotransferase, and total bilirubin. It was observed that patients with abnormal liver tests were significantly statistically older, had more comorbidities and had a higher percentage of unfavourable evolution (death or transfer to intensive care). The conclusion of this paper is that the main causes of liver damage are direct viral aggression, coagulation dysfunction and endothelial damage, and patients with impaired liver function develop more severe forms of COVID-19 which requires special care by a multidisciplinary team that includes a hepatologist.

An Unusual Case of Meckel Diverticulitis Misdiagnosed as an Infected Urachal Cyst

Introduction: Meckel’s diverticulum (MD), a remnant of the omphaloenteric duct, is among the most frequent intestinal malformations. Another embryonic vestige is the urachus, which obliterates, becoming the median umbilical ligament; the failure of this process can lead to a urachal cyst formation. We present a case of Meckel diverticulitis misdiagnosed as an infected urachal cyst. Presentation of case: A 16-year-old girl presented with hypogastric pain, fever and vomiting. She had undergone an appendectomy 6 years prior and no digestive malformation had been documented. In the last 2 years, she had 3 events of urinary tract infections with Escherichia coli, and anabdominal ultrasound discovered a 28/21 mm hypoechogenic preperitoneal round tumor, anterosuperior to the bladder. We established the diagnosis of an infected urachal cyst, confirmed later by magnetic resonance imaging. Intraoperative, we found MD with necrotic diverticulitis attached to the bladder dome. Discussions: Meckel’s diverticulum and urachal cyst (UC) are embryonic remnants. Both conditions are usually asymptomatic, being incidentally discovered during imaging or surgery performed for other abdominal pathology. Imaging diagnosis is accurate for UC, but for MD they are low sensitivity and specificity. For UC treatment, there is a tendency to follow an algorithm related to age and symptoms, but there is no general consensus on whether to perform a routine resection of incidentally discovered MD. Conclusion: Preoperatory diagnosis of MD represents a challenge. We want to emphasize the necessity of a thorough inspection of the small bowel during all abdominal surgical interventions and MD surgical excision regardless of its macroscopic appearance. These two actions seem to be the best prophylaxis measures for MD complications and consequently to avoid emergency surgery, in which case more extensive surgical procedures on an unstable patient may be needed.

A Working Hypothesis on Vesicular Lesions Related to COVID-19 Infection, Koebner Phenomena Type V, and a Short Review of Related Data

SARS-CoV-2 has recently been associated with the reactivation of varicella zoster virus in patients. This is potentially an observation of a local susceptibility of the skin in areas of vesicle formation. This article explores the dermatologic manifestations that have been linked to the SARS-CoV-2 virus, their infectious risk, as well as potential confounding factors. An isotopic response may be occurring due to the occurrence of an immunocompromised district incited by sustained inflammation mediated by inflammatory cytokines.

Gadolinium-based contrast agents in neurofibromatosis type 1 (Review)

Gadolinium (symbol Gd) is the chemical element with atomic number 64 and is aductile rare-earth metal, and +3 is its most frequent oxidation state. Gadolinium has an ionic radius of 0.99 Å and is nearly identical to the one of Ca²⁺. Gd³⁺ and Ca²⁺ can become toxic to biological systems if complete. It slowly reacts with atmospheric oxygen to form a black coating and in nature it is usually found only in an oxidized form. Gadolinium usually has impurities similar to those of other rare-earth metals, when separated, because of their similar chemical properties. Neurofibromatosis type 1 (NF1) or von Recklinghausen's disease is an autosomal dominant disorder of tissues of ectodermal origin, accounting for over 90% of neurofibromatosis cases. Diagnosis is primarily clinical and the central nervous system is commonly involved. The screening of the brain with magnetic resonance (MR) imaging is utilised to evaluate the patients with neurofibromatosis type 1 and as an aid in the diagnosis of asymptomatic patients when clinical criteria are not met.

Effectiveness of 8- and 12-Week Treatment with Ombitasvir/ Paritaprevir/Ritonavir and Dasabuvir in Treatment-Naïve HCV Patients in a Real-Life Setting in Romania: the AMETHYST Study

BACKGROUND AND AIMS

The 12-week regimen of ombitasvir/paritaprevir/ritonavir and dasabuvir (OPrD) has shown high efficacy and tolerability in clinical trials for the treatment of chronic hepatitis C virus (HCV). The shorter 8-week regimen has been recently incorporated into clinical guidelines and on-label indications, but real-world evidence on its use is limited. Given this knowledge gap, the AMETHYST study aimed to evaluate the effectiveness of the 8- and 12-week regimens of OPrD in treatment-naive patients with HCV with mild to moderate liver fibrosis in Romanian clinical practice.

METHODS

This was a secondary data collection study analyzing data from a 1-year Patient Support Program in HCV in Romania. Patients received OPrD treatment for 8 or 12 weeks. The effectiveness endpoint was sustained virologic response 12 weeks post-treatment (SVR12).

RESULTS

A total of 1,835 treatment-naive patients with HCV with mild or moderate fibrosis were included in the study. Of these, 426 and 1,375 completed the 8-week and 12-week regimens, respectively. SVR12 was 98.1% in the 8-week treatment group and 98.7% in the 12-week treatment group.

CONCLUSION

The study provides real-world evidence that 8-week and 12-week treatment regimens of OPrD are highly effective in treatment-naive patients with HCV with mild to moderate liver fibrosis.

Perspectives on skin disorder diagnosis among people living with HIV in southeastern Romania

The beginnings of the human immunodeficiency virus (HIV) pandemic are closely linked to dermatological conditions. A large part of the population living with HIV (PLWH) has a series of skin conditions that determine at some point, a visit to the dermatologist. The introduction of highly active antiretroviral therapy (HAART) more than 20 years ago has diminished the range of dermatological conditions, with improved immunosuppression of CD4 lymphocytes. The study aimed to describe the prevalence of the diagnosed type of skin changes in PLWH receiving antiretroviral therapy and their stratification according to the degree of immunodeficiency. A prospective study was conducted on 57 PLWH evaluated monthly at an HIV outpatient clinic, from a tertiary hospital in southeastern Romania. Clinical examination and dermoscopy revealed the existence of a wide range of dermatological conditions; all 57 patients (100%) being diagnosed with one or more dermatological conditions. As our study shows, the prevalence of different dermatoses among PLWH varies depending on the geographical region. At the same time, under HAART, the image of dermatoses associated with decreased immunity from HIV infection has changed. The skin changes of PLWH no longer fully follow the classical staging, based on the degree of immunosuppression.

The Role of Cytokine in the Diagnosis and Monitoring of Patients with Systemic Infections

Sepsis is an immunologic disorder with a high rate of mortality which is caused by the exacerbation of the inflammatory response. The purpose of this study was to characterise the etiologic spectrum and the profile of the most significant pro-inflammatory and anti-inflammatory citokines in patients with sistemic infections, by analysing the relationship between the type of etiologic agents and the intensity of the inflammatory response. The study was carried out on a number of 33 patients with systemic infections who were hospitalized in the �Saint Parascheva �Infectious Diseases Clinic Hospital in Galati, Romania. The intensity of the inflammatory response was higher in the sepsis with Gram-negative Bacilli (BGN) as compared to the systemic infections produced by Gram-positive Cocci (CGP). In the case of the patients with bacterial etiology (CGP and BGN) there was evidence of an increase levels of analysed cytokines (TNF-a, IL-1, IL-4, IL-6, IL-10), while the fungal etiology was correlated with high serum concentrations of TNF-a. The levels of IL-4 and IL-6 were similar in all patients with systemic infections, regardless of their etiology. The Klebsiella pneumoniae sepsis has led to the occurrennce of high serum levels both in the case of pro-inflammatory and anti-inflammatory citokines. The obtained results outline the necessity of monitoring pro-inflammatory and anti- inflammatory cytokines in sepsis, which might provide clues about the intensity of the generalized inflammatory reaction, representing not only an important diagnosis criteria but also a useful guide in the therapeutic methods chosen and the monitoring of these severe infections.

Antioxidant Profile of Buckwheat Honey from the Republic of Moldova

The honey is a natural substance, whose therapeutic qualities have been developed in parallel with human evolution. Its antioxidant and antiinflammatory properties are due to the polyphenolic compounds. The purpose of this study is to identify and quantify the phenolic compounds and the FTIR spectrum from buckwheat honey from the Balti region, Republic of Moldova. The radical scavenging activity of honey was 83% in the DPPH� reaction system. Phenolic compounds from honey were identified by HPLC-MS method, the significant concentrations being lignans, catechins, isorhamnetin, rutin, apigenin and luteolin. FTIR analysis revealed both the carbohydrate profile in buckwheat honey and the presence of active compounds.

Influence of phytochemicals in induced psoriasis (Review)

Cytokines involved in pathogenesis of psoriasis such as interleukins (IL-1β, IL-6, IL-17, IL-22, IL-23), interferon-α, tumor necrosis factor-α and interferon-γ can also become therapeutic targets. Research currently uses murine models of imiquimod-induced psoriatic-type dermatitis in order to analyze potentially helpful phytotherapeutics for psoriasis treatment: Curcuma longa, Aloe vera, Nigella sativa, Rubia cordifolia, Smilax china, Thespesia populnea, Wrightia tinctoria, Scutellaria baicalensis, Cassia tora, Pongamia pinnata and various Chinese herbal formulas. Psoriasis is a chronic inflammatory disease with complex pathogenic mechanisms that yield abnormal immune responses with clinical and morphological echoes (erythematous, scaly plaques with a histopathological basis made up of alterations i.e. keratinocyte aberrant proliferation, parakeratosis or chronic inflammation). The current therapeutic approach has only been able to manage the disease, without ensuring a certified treatment, thus giving rise to the need for better medications. This novel therapeutic approach has shown promising results in preclinical studies, giving hope for future phytochemical animal-based studies.

Schizophrenia and the Family Burden During the Pandemic

This article focuses on the issue of the burden that families with people with schizophrenia in care are confronted with. The pandemic caused significant disruption to the family dynamics of people caring for individuals with schizophrenia due to their higher risk of infection and worse outcomes. Families with patients with schizophrenia should pay close attention to detect both respiratory and psychiatric symptoms as early as possible. They may need health care professional support, guidance and help to prevent COVID-19 infection among people diagnosed with schizophrenia. However, the issue of the difficulties that families with people diagnosed with schizophrenia face remains a serious matter.

Covid-19 and the Spanish Flu. From Suffering to Resilience

This paper is an overview of how the pandemic affected society during the Spanish flu period and its impact on the psychiatric hospitals and asylums of that period. The continuous changes of situations in the context of the current pandemic and the attempt of individuals to adapt led to comparisons between COVID-19 and the Spanish flu of 1918-1919. The progress of medicine and intervention measures are still struggling with the strength of influenza viruses and their ability to spread around the world has grown exponentially. The study analyzes how this new pathology can influence the attitude of individuals towards the disease, their thoughts, emotions and behaviors so as to prevent the onset of symptoms in the field of mental health and contribute to the well-being of the population.

Comparative Effectiveness of Vancomycin and Metronidazole for the Initial Episode of Nonsevere Clostridium Difficle Infection

The infection with Clostridium difficile (CDI), which appeared at epidemic level, after acquiring the germ of some fluoroquinolone resistance genes, initially considered nosocomial infection and adverse effect post-antibiotic therapy, is affecting more and more people without risk factors and extending into the community. This paper proposes an analysis of the two main antibiotics used in therapy: metronidazole and vancomycin, the evidence of efficacy in the literature and the chemical stability of antibiotics in simulated gastrointestinal fluid. Based on UV-Vis absorption spectra, it can be considered that there are no major changes in the chemical structure of the investigated drugs in the presence of gastro-duodenal conditions. Clinical impact of comparative treatment with metronidazole and vancomycin has also been studied, in a group of 720 CDI patients hospitalized during the period 1.01.2017-31.12.2018 in the Clinical Hospital St. Parascheva of Infectious Diseases Galati. From this group, two subgroups were selected, one of 284 patients receiving oral vancomycin treatment and one group of 62 patients receiving oral metronidazole for an initial nonsevere episode of CDI. The number of days from the beginning of the treatment until the normalization of the stool, the length of hospitalization, the number of days of antibiotic treatment and the percentage of relapses were comparable in the two groups, the percentage of deaths in the first 30 days from the episode of CDI was higher in the vancomycin-treated group, probably due mainly to the severe comorbidities of these patients. The conclusion of the study is that the treatments with metronidazole and vancomycin, of the initial episode, nonsevere of CDI are comparable as a therapeutic response, provided that the patients treated with metronidazole do not associate hepatic, renal or neurological impairment due to the risk of adverse reactions.

The Therapeutic Relevance of Vitamin E

Maintaining cellular homeostasis in the context of its normal metabolic function is achieved by establishing the balance between its own antioxidant capacity and the level of harmful compounds resulting from the mitochondrial activity and the immune system. One of the antioxidants involved in this process is vitamin E with its most active form - alpha-tocopherol, which exerts its functions through vitamin C. The main functions of this antioxidant are: regulation of platelet aggregation, cellular signaling, antioxidation. The therapeutic relevance of vitamin E has increased due to the incrimination of oxidative stress as a link in the pathophysiology of many chronic diseases. Respectively, the role most targeted is that of antioxidant.

Efficeint Administration of Human Albumin in Clostridium Difficile Infection

Albumin is the most important protean component of the plasma. Human albumin is a concentrate of plasmatic proteins from the blood with multiple therapy uses. The study aims to highlights the efficient administration of human albumin i.v. in hypoalbuminemia due to diarrhea with Clostridium difficile. Administering human albumin i.v. in symptomatic hypoalbuminemia manifested by the occurrence of edemas was followed by symptoms remission and ensured a favorable evolution.

Clostridium Difficile Infection Complicated By Toxic Megacolon In Immunocompetent Patient

Toxic megacolon can be a form of severe clinical course of the infection with Clostridium difficile (ICD), life-threatening, requiring a particular course of treatment. Infection with Clostridium difficile in the Galati Infectious Disease Hospital presents rising number of cases, namely 172 cases in 2014, 271 cases in 2015 and 301 cases in 2016 with clinical evolutions with different severity degrees, including toxic megacolon and death. Among 744 patients with ICD in our clinic, since 1st January 2014 to 31 December 2016. The frequency of toxic megacolon (TM) was 0,537%, so: 3 toxic megacolon cases with favorable evolution with treatment with vancomycin and metronidazole and just one case whose evolution was aggravated under this therapy and evolved favorably under treatment with tigecycline. The work presents this last case of ICD occurred in a 69 years old, immunocompetent man with unknown concomitant chronic diseases which undergoes surgery for bilateral inguinal hernia and receives antibiotherapy with cephalosporin IIIrd generation during surgery and after 7 days develops medium degree ICD with score Atlas 3 and receives therapy with oral vancomycin. He presents clinical aggravation during this therapy with the occurrence of colon dilatation, ascites and right pleurisy at ultrasound and therapy associated with metronidazole is decided. Clinical aggravation continues in this combined therapy with defining the clinical, colonoscopy and tomography criteria for TM and is decided surgical monitoring and replacing antibiotherapy with tigecycline. Evolution is favorable with tigecycline without surgical intervention.
