ABSTRACT

Coronavirus disease 2019 (COVID-19) is a fatal pandemic viral disease caused by the severe acute respiratory syndrome corona virus type-2 (SARS-CoV-2). The aim of this study is to observe the associations of IL-6, SARS-COV-2 viral load (RNAemia), IL- 6 gene polymorphism and lymphocytes and monocytes in peripheral blood with disease severity in COVID-19 patients. This study was carried out from March 2021 to January 2022. RT-PCR positive 84 COVID-19 patients and 28 healthy subjects were enrolled. Blood was collected to detect SARS-COV-2 viral RNA (RNAemia) by rRT-PCR, serum IL-6 level by chemiluminescence method, SNPs of IL-6 by SSP-PCR, immunophenotyping of lymphocytes and monocyte by flow cytometry. Serum IL-6 level (pg/ml) was considerably high among critical patients (102.02 +/- 149.7) compared to severe (67.20 +/- 129.5) and moderate patients (47.04 +/- 106.5) and healthy controls (3.5 +/- 1.8). Serum SARS-CoV-2 nucleic acid positive cases detected mostly in critical patients (39.28%) and was correlated with extremely high IL-6 level and high mortality (R =.912, P < 0.001). Correlation between IL-6 and monocyte was statistically significant with disease severity (severe group, p < 0.001, and 0.867*** and critical group p < 0.001 and 0.887***). In healthy controls, moderate, severe and critically ill COVID-19 patients, IL-6 174G/C (rs 1800795) GG genotype was 82.14%, 89.20%, 67.85% and 53.57% respectively. CC and GC genotype had strong association with severity of COVID-19 when compared with GG genotype. Significant statistical difference found in genotypes between critical and moderate groups (p < 0.001, OR-10.316, CI-3.22-23.86), where CC genotype was associated with COVID-19 severity and mortality. The absolute count of T cell, B cell, NK cell, CD4+ T cells and CD8+ T cells were significantly decreased in critical group compared to healthy, moderate and severe group (P < 0.001). Exhaustion marker CD94/NKG2A was increased on NK cells and CD8+ cytotoxic T cell among critical and severe group. Absolute count of monocyte was significantly increased in critical group (P < 0.001). Serum IL-6, IL-6 174 G/C gene and SARS-CoV-2 RNAaemia can be used in clinical practice for risk assessment;T cell subsets and monocyte as biomarkers for monitoring COVID-19 severity. Monoclonal antibody targeting IL-6 receptor and NKG2A for therapeutics may prevent disease progression and decrease morbidity and mortality.Copyright © 2023 Elsevier Inc.

ABSTRACT

Background and Objectives: Due to the high prevalence of COVID-19 disease and its high mortality rate, it is necessary to identify the symptoms, demographic information and underlying diseases that effectively predict COVID-19 death. Therefore, in this study, we aimed to predict the mortality behavior due to COVID-19 in Khorasan Razavi province. Method(s): This study collected data from 51, 460 patients admitted to the hospitals of Khorasan Razavi province from 25 March 2017 to 12 September 2014. Logistic regression and Neural network methods, including machine learning methods, were used to identify survivors and non-survivors caused by COVID-19. Result(s): Decreased consciousness, cough, PO2 level less than 93%, age, cancer, chronic kidney diseases, fever, headache, smoking status, and chronic blood diseases are the most important predictors of death. The accuracy of the artificial neural network model was 89.90% in the test phase. Also, the sensitivity, specificity and area under the rock curve in this model are equal to 76.14%, 91.99% and 77.65%, respectively. Conclusion(s): Our findings highlight the importance of some demographic information, underlying diseases, and clinical signs in predicting survivors and non-survivors of COVID-19. Also, the neural network model provided high accuracy in prediction. However, medical research in this field will lead to complementary results by using other methods of machine learning and their high power.Copyright © 2022 The Authors.

ABSTRACT

Introduction: Following the lifting of generalised restrictions and universal masking, severe acute respiratory syndrome coronavirus 2 (SARS-CoV- 2)- infected patients, especially the clinically extremely vulnerable (CEV) haematology patients, are at an increased risk for other respiratory viral coinfections;therefore, physicians need to be cognizant about excluding other treatable respiratory pathogens. Here, we report coinfection with SARS-CoV- 2 and other respiratory pathogens in patients with haematological cancers presenting to a large tertiary care hospital. Method(s): From July 2022-December 2022, patients with haematological disorders were screened for SARS-CoV- 2 and other 10 common respiratory pathogens by PCR. We performed a retrospective analysis of patients with concurrent respiratory viruses and will prospectively evaluate the same from Jan 2023 to March 2023. Result(s): During this period a total of 322 inpatients had routine screening and additional 6213 swabs were done in the outpatient/ambulatory setting, of which 294 were positive in 221 patients. We excluded all patients who had a single positive PCR swab result and specifically analysed only patients with coinfections. We identified 30 patients (14%) who had respiratory coinfections with 73 viral infections/reactivations over 6 months period, which represented 25% of all positive swabs: 25 inpatients (19 symptomatic/6 asymptomatic) and 48 in outpatients (32 symptomatic/16 asymptomatic). The median age of the cohort was 47.3 years (21-77). Patients were post allograft (n = 15), autograft (n = 7), post CART (n = 5) and postchemotherapy (n = 4). Of the 30 cases, 13 patients had concurrent infections: 5 SARS-CoV2, 10 Respiratory syncytial virus (RSV), 7 Rhino and 4 Influenza A, with all patients having dual viral infection. The remaining 17 patients had multiple viral infections but separated by a median of 54 days (range 27-137 days): 16 SARS-CoV2, 5 RSV, 6 Rhino, 2 Parainfluenza, 2 Adeno and one each of Influenza A, Influenza B, and metapneumovirus. Of the treatable infections (n = 46), 22% were detected on routine asymptomatic swabbing, with 50% of SARS-CoV2 detected on routine swabs. All 8 patients with Influenza were treated with oseltamivir, of 16 RSV cases one was treated with oral ribavirin and of the 22 SARS-CoV2 patients, 5 were treated (4 Paxlovid and 1 Remdesivir). No patients needed intensive care support and no deaths were reported. Conclusion(s): The burden of respiratory coinfections in CEV cohort has a significant impact on respiratory isolation and management, including appropriate & timely initiation of therapy for treatable viral infections. Although mortality was not increased secondary to respiratory coinfections and none needed intensive care, larger prospective cohorts are needed to assess the exact impact.

ABSTRACT

The safety of COVID-19 pharmacotherapy is a relevant issue, first of all, because of the current lack of experience with using particular medicinal products and with off-label prescribing. The aim of the study was to analyse information on potential adverse drug reactions (ADRs) and their predictors in etiology- and pathogenesis-oriented COVID-19 therapy. According to literature data, the main clinically significant risk factors for COVID-19 patients to develop an ADR are the duration of their hospital stay, combined use of antivirals, polypharmacy, and their history of drug allergies. The most common adverse reactions to antivirals, to virus-neutralising antibodies, and to human anti-COVID-19 immunoglobulin and convalescent plasma are, respectively, gastrointestinal and hepatobiliary disorders;gastrointestinal disorders, neurological disorders, and allergic reactions;and transfusion reactions (fever, chills, etc.). For pathogenesis-oriented therapy with systemic glucocorticosteroids, the most characteristic ADR is hyperglycaemia. Janus kinase inhibitors and interleukin inhibitors are most often associated with gastrointestinal disorders and hypertransaminasemia;neutropenia is also characteristic of a number of interleukin inhibitors. Haemostatic adverse reactions to anticoagulants depend on the patient's dosing regimen and condition. Drug-drug interactions are a common problem in COVID-19 treatment, with the combination of nirmatrelvir and ritonavir showing the largest number of significant interactions attributed to their pharmacokinetics. Currently, there is data on the role of pharmacogenetic biomarkers in the safety and clinical outcomes of COVID-19 therapy. Thus, to improve the safety of COVID-19 therapy, an integrated approach is needed that will take into account both the clinical, demographic, and pharmacogenetic predictors of ADRs and the risk of drug-drug interactions.Copyright © 2023 Safety and Risk of Pharmacotherapy.

ABSTRACT

Background: Patients with cancer are at a higher risk of getting infected with the severe acute respiratory syndrome coronavirus 2 owing to their immunocompromised state. Providing care to these patients amidst the first wave of the coronavirus disease-2019 (COVID-19) pandemic was extremely challenging. Objective(s): This study was aimed at evaluating the clinical profile and disease-related outcomes of pediatric patients with hematological illnesses and cancer. Material(s) and Method(s): This retrospective study was conducted at a tertiary care center in North India during the first wave of the pandemic from March 2020 to December 2020. Children aged up to 18 years, who were treated for a hematological illness or malignancy or underwent hematopoietic stem cell transplantation (HSCT) and tested positive for COVID-19 regardless of symptoms were included in the study. Baseline demographic data related to the age, diagnosis, treatment status, and chemotherapy protocol used were collected. Outcomes including the cure rates, comorbidities, and sequelae were recorded. Result(s): A total of 650 tests for COVID-19 were performed for 181 children;22 patients were found to be COVID-19 positive. The most common diagnosis was acute leukemia (63.6%). None of the patients developed COVID-19 pneumonia. The majority of patients had asymptomatic infection and were managed at home. Among those with a symptomatic infection, the most common symptoms were fever and cough. A total of 3 (13.6%) patients needed oxygen therapy, one developed multisystem inflammatory syndrome of children leading to cardiogenic shock. Three patients required intensive care or respiratory support;all the patients had favorable clinical outcomes. The median time from the onset of COVID-19 to a negative result on the reverse transcription-polymerase chain reaction test was 21.3 days. Cancer treatment was modified in 15 patients (68.2%). Conclusion(s): Our results suggest that children with hemato-oncological illnesses rarely experience severe COVID-19 disease. The impact of the first wave of COVID-19 primarily manifested as disruptions in the logistic planning and administration of essential treatment to these children rather than COVID-19 sequelae.Copyright © 2021 Cancer Research, Statistics, and Treatment Published by Wolters Kluwer - Medknow.

ABSTRACT

Background: There is still no specific treatment strategy for COVID-19 other than supportive management. The potential biological benefits of ozone therapy include reduced tissue hypoxia, decreased hypercoagulability, modulated immune function by inhibiting inflammatory mediators, improved phagocytic function, and impaired viral replication. This study aimed to evaluate the effect of intravenous ozonated normal saline on patients with severe COVID-19 disease. Method(s): In this study, a single centralized randomized clinical trial was conducted on 80 hospitalized patients with severe COVID-19. The patients were selected by random allocation method and divided into two groups A and B. In group A (control group), patients were given standard drug treatment, and in group B (intervention group), patients received ozonated normal saline in addition to the standard drug treatment. In the intervention group, 400 mL of normal saline was weighed by 40 mug/ kg of body weight and was injected into patients within 15 to 30 minutes (80 to 120 drops per minute). This process was done daily every morning for a week. Primary and secondary outcomes of the disease included changes in the following items: length of hospital stay, inflammatory markers including C-reactive protein (CRP), clinical recovery, arterial blood oxygen status, improvement of blood disorders such as leukopenia and leukocytosis, duration of ventilator attachment, and rapid clearance of lung lesions on CT scans. The need for intensive care unit (ICU) hospitalization, the length of ICU stay, and the mortality rate in patients of the two groups was compared. Result(s): According to the results of the initial outcome variable analysis, the probability of discharge of patients who received the normal ozonated saline intervention was 33% higher than patients who did not receive this intervention;however, this relationship was not statistically significant (HR = 0.67, 95%, CI = 0.42-1.06, P value = 0.089). The chance of ICU hospitalization in patients of the intervention group was three times more than that of the comparison group, but this relationship was not significant (odds ratio = 4.4 95% CI = 1.32-14.50, P value = 0.016). The use of ozonated normal saline was found to increase the risk of death by 1.5 times but this relationship was not statistically significant (odds ratio = 1.5, 95% CI = .24-9.75, P value = 0.646). Ozonated normal saline had a significant effect on changes in respiration rate (in the intervention group the number of breaths was decreased) and the erythrocyte sedimentation rate (in the intervention group the erythrocyte sedimentation rate was increased);however, it had no significant effect on other indicators. Conclusion(s): The present study showed that ozone therapy in hospitalized patients with severe COVID-19 could help improve some primary and secondary outcomes of the disease. Governments and health policymakers should make ozone therapy an available care service so that the need for advanced treatment facilities decreases;consequently, this measure may improve patient safety, prevent lung tissue destruction, and control cytokine storms in patients. Additionally, health decision-makers need to aim for the effective clinical improvement of patients, especially severe ones, and the reduction of their mortality. However, further large-scale multicenter studies with larger sample sizes considering drug side effects and other variables influencing the clinical course of COVID-19 can provide more information on the effectiveness and importance of ozone therapy.Copyright © 2023 The Author(s);Published by Kerman University of Medical Sciences.

ABSTRACT

Introduction: We aimed to describe the incidence, risk factors, and clinical outcomes of bacterial and fungal co-infections and superinfections in intensive care patients with COVID-19 in a retrospective observational study. Method(s): A retrospective cohort of intensive care patients with confirmed SARS-CoV-2 by PCR was analysed from January to March 2021. This was contrasted to a control group of influenza-positive patients admitted during 2012-2022. Patient demographics, microbiology and clinical outcomes were analysed. Result(s): A total of 70 patients with confirmed SARS-CoV-2 were included;6 (8.6%) of 70 had early bacterial isolates identified rising to 42 (60%) of 70 throughout admission. Blood cultures, respiratory samples, and urinary samples were obtained from 66 (94.3%), 18 (25.7%) and 61 (87.1%) COVID-19 patients. Positive blood culture was identified in 13 patients (18.6%). Bacteraemia resulting from respiratory infection was confirmed in 3 cases (all ventilator-associated). Line-related bacteraemia was identified in 9 patients (6 Acinetobacter baumannii, 4 Enterococcus spp. and 1 Pseudomonas aeruginosa and 1 Micrococcus lylae). No concomitant pneumococcal, Legionella or influenza co-infection was detected. Invasive fungal infections with Aspergillus spp. were identified in 2 cases. Pneumococcal coinfections (7/68;10.3%) were identified in the control group of confirmed influenza infection;clinically relevant bacteraemias (6/68;8.8%), positive respiratory cultures (15/68;22.1%). The rate of hospital- acquired infections was 51.4% for COVID-19 and 27.9% for influenza. Longer intensive care stay, type 2 diabetes, obesity and hematologic diseases were independent risk factors for superinfections in the COVID-19 cohort. Conclusion(s): Respiratory coinfections occurred in influenza but not in COVID-19 patients. The rate of hospital-acquired infections (51.4% for COVID-19;27.9% for influenza) was unexpectedly high in both groups.

ABSTRACT

Background: COVID-19 infection during pregnancy is associated with an increased risk of stillbirth, likely due to placental insufficiency through the associated inflammatory response and hypoperfusion. A spectrum of associated placental changes has been reported. Whilst pregnancy alone is a hypercoagulable state, concurrent COVID-19 further increases the risk of coagulopathy. Disseminated intravascular coagulation (DIC) is uncommon in pregnancy but is increased in both COVID-19 infection and fetal death in utero (FDIU). Method(s): Case report. Informed written consent was obtained from the patient. Result(s): A 31-year-old G5P2 presented with a FDIU at 23 + 3 weeks gestation, in the setting of maternal COVID-19 infection without respiratory symptoms or oxygen requirements. The pregnancy had been uncomplicated, and her presenting issue was two days of reduced fetal movements, when FDIU was confirmed on ultrasound. On admission, the case was further complicated by disseminated intravascular coagulopathy (DIC). This DIC could have resulted from COVID-19 infection, FDIU or a combination of both. Placental histopathology showed evidence of inflammation, with chronic histiocytic intervillositis (CHI) and massive perivillous fibrin deposition (MPFD). The inflammatory response, evidenced by histopathological findings of CHI and MPFD, likely contributed to placental insufficiency and FDIU. Conclusion(s): COVID-19 infection is associated with increased risk of hematological abnormalities, placental inflammation and pregnancy loss. This case is the first to report both DIC and CHI in the context of FDIU in COVID-19 infection. We present this case to highlight the impact of COVID-19 infection on placental function, coagulation disturbances and subsequently adverse pregnancy outcomes.

ABSTRACT

Background: Previous studies had demonstrated that patients with hematologic malignancies had suboptimal antibody response after receiving COVID-19 vaccines, especially among those having previously treated with anti- CD20 monoclonal antibodies. Method(s): Adult patients with non-Hodgkin's lymphoma or chronic lymphocytic leukemia (CLL) were enrolled before receiving the second dose of SARS-CoV-2 vaccine. Determinations of anti-SARS-CoV-2 spike and nucleocapsid IgG titers were performed every 1-3 months, after they received the second and the third dose of SARS-CoV-2 vaccine, respectively. Patients were excluded from analysis if they were diagnosed with COVID-19. All serum samples were tested for anti-nucleocapsid antibody and those tested positive were excluded from subsequent analyses. Result(s): A total of 85 participants were enrolled, including 42 (49.4%) with diffused large B-cell lymphoma, and 13 (15.3) with follicular lymphoma and 9 with CLL. 72 (84.7%) participants had received anti-CD20 monoclonal antibodies, with a median interval of 24 months between last anti-CD20 treatment and the second dose of vaccine, and 21 (24.7%) had HIV infection. Factors associated with failure to achieve an anti-spike IgG titer >141 BAU/ mL within 12 weeks after the second dose of vaccine included HIV infection (adjusted odds ratio [aOR], 0.14;95% CI, 0.04-0.51), active hematologic disease (aOR, 5.50;95% CI 1.42-21.32), receipt of anti-CD20 monoclonal antibodies (aOR, 6.65;95% CI 1.52-29.07), and receipt of two doses of homologous mRNA vaccination (aOR, 0.17;95% CI 0.05-0.56). In the participants having previously treated with anti-CD20 regimen, only 8.6% achieved an antibody response ( >141 BAU/mL) in the first year, while 78.3% achieved anti-spike IgG titer > 141 BAU/mL after two years post B-cell depleting treatment. After the third dose of SARS-CoV-2 vaccine, 53.6% achieved an antispike IgG titer > 141 BAU/mL in the first year post anti-CD20 treatment. Conclusion(s): Our study demonstrated that previous treatment with anti-CD20 monoclonal antibodies was associated a lower antibody response among patients with lymphoproliferative disorders receiving two doses of SARS-CoV-2 vaccine. While two doses of SARS-CoV-2 vaccines might not be sufficient even one year apart from the last dose of rituximab, a third dose of vaccine may boost anti-spike IgG particularly in the subset of recent exposure to rituximab. Anti-spike IgG determined 1-3 months after the second (A) / third (B) dose of COVID-19 vaccine, stratified by the interval between last anti-CD20 regimen and the second / third dose of COVID-19 vaccine.

ABSTRACT

Introduction. The connection between the health of the oral cavity and general health is well known, because oral diseases can impair general health, but the health of the oral cavity can also be impaired due to the existence of a systemic disease. The structures of the oral cavity can be affected directly by the disease or indirectly due to the influence of drugs or due to the patient's behavior. Oral manifestations affect hard dental tissues, supporting tissues and oral mucosa. The changes that occur can lead to pain and discomfort, cause concern for the child and parents, and can be completely asymptomatic. Doctors of dental medicine are often the first to suspect the presence of a disease during a routine examination, because the area of the oral cavity is easily accessible for early detection of pathological changes. That way, they can directly influence the course and therapy of the systemic disease by early recognition and referring the patient to further tests. Aim of the lecture is to present oral manifestations of gastrointestinal diseases, diabetes, blood diseases, bacterial diseases and viral diseases with a special focus on COVID-19.

ABSTRACT

Case Report: A 26-year-old woman with a history of warm autoimmune hemolytic anemia, immune thrombocytopenia, triple positive antiphospholipid syndrome, and chronic migraine presented to the emergency department with worsening generalized fatigue for one week associated with headache, dyspnea on exertion, nausea, vomiting and lightheadedness. Of note, she had received her second dose of mRNA COVID-19 vaccine 4 days prior to presentation. On admission, patient was found to be severely anemic with a hemoglobin of 4.3g/dL which is decreased from her baseline hemoglobin of 9-10.5g/dL;however, W-AIHA precluded the administration of blood product until adequate blood with the appropriate antibodies could be acquired. During the hospitalization, hemoglobin decreased to 3.3g/dL. Patient was then administered the most compatible blood product which she tolerated well. Hematology was consulted who started the patient on hydroxychloroquine, high dose methylprednisolone, and Intravenous Immunoglobulin (IVIG). Throughout the admission, the patient remained asymptomatic. After 2 days of IVIG, three days of high dose glucocorticoids, and one unit of packed red blood cells, the patient's hemoglobin increased to 7.2g/dL. Patient was discharged home on prednisone taper and hydroxychloroquine. Conclusion(s): Episodes of hemolytic anemia after either the first or second dose of mRNA COVID vaccines are rare and have occurred in patients with known hematological pathology as well as patients without any history of hematologic or immunologic disorders. When taking the history of patients presenting with hemolytic anemia, it is important to query recent vaccinations as, while rare, mRNA COVID vaccine may well be the etiology. While this ultimately will likely not change patient management, this information would be beneficial for further study.

ABSTRACT

Objective: Adverse drug reactions increase morbidity and mortality, prolong hospital stay and increase healthcare costs. The primary objective of this study was to determine the prevalence of emergency department visits for adverse drug reactions and to describe their characteristics. The secondary objective was to determine the predictor variables of hospitalization for adverse drug reactions associated with emergency department visits. Method(s): Observational and retrospective study of adverse drug reactions registered in an emergency department, carried out from November 15th to December 15th, 2021. The demographic and clinical characteristics of the patients, the drugs involved and the adverse drug reactions were described. Logistic regression was performed to identify factors related to hospitalization for adverse drug reactions. Result(s): 10,799 patients visited the emergency department and 216 (2%) patients with adverse drug reactions were included. The mean age was 70 +/- 17.5 (18-98) years and 47.7% of the patients were male. A total of 54.6% of patients required hospitalization and 1.6% died from adverse drug reactions. The total number of drugs involved was 315 with 149 different drugs. The pharmacological group corresponding to the nervous system constituted the most representative group (n = 81). High-risk medications, such as antithrombotic agents (n = 53), were the subgroup of medications that caused the most emergency department visits and hospitalization. Acenocumarol (n = 20) was the main drug involved. Gastrointestinal (n = 62) disorders were the most common. Diarrhea (n = 16) was the most frequent adverse drug reaction, while gastrointestinal bleeding (n = 13) caused the highest number of hospitalizations. Charlson comorbidity index behaved as an independent risk factor for hospitalization (aOR 3.24, 95% CI: 1.47-7.13, p = 0.003, in Charlson comorbidity index 4-6;and aOR 20.07, 95% CI: 6.87-58.64, p = 0.000, in Charlson comorbidity index >= 10). Conclusion(s): The prevalence of emergency department visits for adverse drug reactions continues to be a non-negligible health problem. High-risk drugs such as antithrombotic agents were the main therapeutic subgroup involved. Charlson comorbidity index was an independent factor in hospitalization, while gastrointestinal bleeding was the adverse drug reaction with the highest number of hospital admissions.Copyright © 2022 Sociedad Espanola de Farmacia Hospitalaria (S.E.F.H)

ABSTRACT

Background: Vaccination is considered the most effective preventive strategy to fight COVID-19. The aim of this study was to evaluate two critical concerns about: 1) the kinetic response of IgG and IgM, and: 2) the hematological abnormalities in a longitudinal cohort of health-care workers (HCW) who had received 2 doses of BNT162b2 mRNA-based vaccine. Method(s): Blood and nasopharyngeal swabs were collected from 46 volunteers' participants, previous written consensus, with presumable no symptoms of COVID-19. Anti-SARS-CoV-2 serum immunoglobulin G (IgG) and M (IgM) and hematological parameters were examined. Multivariable mixed-effects models for repeated measure analysis were adopted to evaluate time changes in IgG, IgM and hematological parameters, and to investigate associations with vaccination response. Result(s): Forty-six subjects (N.=46;31.8% men;68.2% women;mean age near 36 years-old) were enrolled among healthcare workers of IRCCS MultiMedica (Milan, Italy). Overall, increase in serological IgG concentration appeared mainly between 21-28 days after the 1st dose, whereas IgM did not reach positivity in all cases. Mean blood cells counts were in normal range but we observed a significant reduction of total white blood cells and absolute lymphocyte counts after the 1st dose, persisting until the day 28. The increase of monocytes and neutrophils the day after the 1st dose subsequently decayed significantly. Eosinophils concentration showed a tendency to increase over time. Peripheral blood smear showed a growing frequency of atypical lymphocytes (lympho-variants), and of plasmacytoid forms, whereas no difference was found in large granular lymphocytes (LGL), although a decay after the boost was evident. The stratification of subjects, relative to the timing of IgG increase, showed the occurrence of 3 different patterns after vaccination, namely early-responders (R+), late-responders (R-) and pauci-responders (PR) with a peculiar kinetics of hematological parameters. Lymphocytes were significantly associated with total IgG: lower in R+ and PR compared to R- (P=0.0193 and P=00054, respectively). Conclusion(s): In healthy subjects, anti SARS-CoV-2 vaccination induced a variety of non-pathologic abnormalities. The response to vaccination was not equal in the groups examined.

ABSTRACT

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is named as the coronavirus disease of 2019 (COVID-19). Patients with SARS-CoV-2 infection experience a wide range of symptoms and they are at the risk of various systemic complications. Besides the pulmonary complications, COVID-19 cases may develop cardiovascular and hematological complications. This study aimed to review the most important hematological and cardiovascular complications caused by SARS-CoV-2 infection. Method(s): The English databases, including Pubmed, ScienceDirect, Cochrane Library, Scopus, and Google Scholar, were searched. The published papers were selected and reviewed based on the subject of this study. Result(s): The review of the literature showed that several cardiovascular complications related to COVID-19, including acute myocardial infarction, cardiomyopathy, acute heart failure, and venous thromboembolic events due to coagulation abnormalities, have been reported. COVID-19 associated hematological complications include elevated levels of hematological factors including C-reactive pro-tein, lactate dehydrogenase, procalcitonin, and ferritin. Furthermore, the levels of blood cells, including lymphocytes and thrombocytes, can be reduced. Conclusion(s): This study reviewed COVID-19-associated cardiovascular and hematopoietic complica-tions. In conclusion, the patients may experience a wide range of cardiovascular and hematological is-sues during the illness. These complications are often associated with the need for ICU support and care which imposes further costs to the healthcare system. So the healthcare team must consider the possible complications when treating COVID-19 patients to reduce the treatment costs and mortality of patients.Copyright © 2021 Bentham Science Publishers.

ABSTRACT

BACKGROUND: The maternal mortality rate is an indicator that reflects the mother's health status, especially the risk of death for the mother during pregnancy and childbirth. Measles, Mumps, and Rubella (MMR) has a close relationship with efforts to increase human development. Therefore, efforts are needed to reduce MMR by identifying the factors that influence MMR. AIM: The aim of the study was to analyze the factors causing the incidence of Maternal Death in East Java Province. METHOD(S): The research design used in this research is a quantitative research using descriptive-analytical. The population of this research is districts/cities in East Java Province, with a sample of 38 districts/cities. The research period starts from August to September 2021. Data analysis using grouping and percentage of cases. RESULT(S): The results of the study found that cases of maternal death in East Java due to postpartum hemorrhage in 2021 were 131 cases. Cases due to hypertension as many as 115 cases. Cases due to infection as many as 25 cases. The incidence of maternal death due to abortion is 1 case. There were 13 cases of maternal death due to blood disorders. There were 6 cases of maternal death due to metabolic disorders - cases of maternal death due to Heart as many as 54 cases. Maternal deaths due to COVID-19 were 793 cases. CONCLUSION(S): Factors causing maternal death in East Java Province, namely, hypertension bleeding, infection, abortion, blood disorders, heart metabolic disorders, and COVID-19. The most influential factor in maternal mortality in 2021 is COVID-19.Copyright © 2023 Maharani Maharani, Sutrisno Sutrisno.

ABSTRACT

Background: Determination of predictors of mortality from COVID-19 is important. In general older people have a greater risk of death from COVID-19. The study aimed to investigate whether age is a risk factor of mortality in patients (pts) with hematological diseases. Material(s) and Method(s): Retrospective analysis of medical cards of pts with hematological diseases and confirmed by PCR test COVID-19 in 2020-2021 at the City Hematology Center (Dnipro, Ukraine) was conducted. Result(s): The study included medical cards of 56 pts. 35 (62.5%) women, median age 60 (47-65.5) years. The overall mortality was 35.7%. According to ROC-analysis the age 55 years and less (23 pts) was statistically significant in mortality prediction, with sensitivity 70% and specificity 75%, AUC 0.74, p=0.002. Mortality rate was 60.9% in group of "younger" pts VS 18.2% in another group (p=0.001). Then we compared the profile of hematological diseases in these pts and have identified that they more often had acute leukemia-in 47.8% VS 12.1% in another group (p=0.003) but less common had multiple myeloma - 0% VS 30.3%, p=0.004. Other diseases were equally common. Among key indicators in CBC test, Hb was lower in "younger" pts - 81 (70-98) g/l VS 103.5 (81-122.5) g/l, (p=0.03). However, HB alone has not been shown to be predictor of mortality (p=0.2 by logistic regression). Other indicators were statistically equal. Conclusion(s): Hematologic pts younger than 55 years of age have a higher risk of death from COVID-19, which is most likely due to the higher prevalence of acute leukemia among them. This category of pts requires proactive management tactics even in case of a mild onset of COVID-19.

ABSTRACT

Introduction: Thrombotic thrombocytopenic purpura (TTP) is a rare thrombotic microangiopathy characterized by severe thrombocytopenia, microangiopathic hemolytic anemia, and organ ischemia ascribable to platelet-rich microthrombi. TTP is related to a severe deficiency in ADAMTS13, the specific von Willebrand factor-cleaving metalloprotease. The aim of our study is to analyze the clinical characteristics, treatment and outcome of patients with TTP. Method(s): We retrospectively analyzed 15 patients with TTP treated Farhat Hached hospital, Sousse, Tunisia, from2004 to 2021. Result(s): Among the 15 patients, there were 7 males and 8 females, with a median age of 45,5 (30~72) years. Two of them had evolutive cancer and 1 had covid-19 vaccination 3 months earlier. Twelve patients had neurological presentations (80%), 4 had mucocutaneous bleeding and 2 had fever. Biology showed thrombopenia, mechanical hemolytic anemia in all patients and renal failure in 2 patients. No abnormalities in coagulation tests were detected. The ADAMTS13 activity was performed in only 3 patients (Due to test unavailability) showing a level <=10% in all 3 patients. All patients were treated with plasma exchange/ plasma infusion + glucocorticoid, combined with rituximab in 2 cases. Ten patients showed complete remission, 1 relapsed within the first year, 2 died and 2 others were lost to follow-up. Discussion/Conclusion: Most TTP patients presented with the triad of microangiopathic anemia, thrombocytopenia, and neurologic abnormalities and improved with plasma therapy.

ABSTRACT

Individuals with kidney failure face a future requiring long-term treatment with either dialysis or renal transplantation. Renal transplantation is the preferred form of renal replacement therapy, and is associated with a better quality of life, and usually increased longevity. Unfortunately, owing to excessive co-morbidities, only 30% of patients who develop end-stage renal failure are fit enough for transplantation. Over 90% of kidney transplants still function after 1 year, and most function for >15 years. Improvements in transplant outcomes are attributable to advances in histocompatibility testing, organ procurement, organ preservation, surgical techniques and perioperative care. Long-term outcomes have shown only minor improvements over the last two decades, although this should be considered in the context of deteriorating organ quality as older deceased donors with increasing co-morbidity are used more often to satisfy the need for donor organs. An overall increase in deceased donor numbers has boosted transplant activity in the UK, and it is hoped this will continue with the adoption of the 'opt-out' consent system. Living donor activity remains stable, but the use of non-directed altruistic donation and the living donor exchange scheme have reduced the need for higher immunological risk incompatible transplantation. The COVID-19 pandemic has reduced transplant rates globally, although national transplant systems are now recovering.Copyright © 2022
