Could cooling dialysate improve inflammatory and nutritional status of hemodialysis patients?

BACKGROUND: It has been shown that dialysate cooling (lowering the dialysate temperature to 0.5 °C below central body temperature) reduces the incidence of intradialytic hypotension. Other influences on hemodialysis patients, however, have not been adequately investigated. The purpose of this study was to determine the impact of individualized dialysate cooling on nutritional and inflammatory parameters in chronic hemodialysis (HD) patients. METHODS: Seventy HD patients were separated into two groups: group A: (control group) standard dialysate temperature was 37 °C, and group B: (intervention group) dialysate temperature was 0.5 °C below core body temperature. In addition to routine laboratory tests, blood pressure, anthropometric measurements, inflammatory markers, and the malnutrition inflammation score (MIS) were calculated. RESULTS: After six months of dialysate cooling, intradialytic hypotension episodes were much less prevalent in the intervention group (p = 0.001). Serum ferritin, transferrin saturation (TSAT), high sensitive C-reactive protein (HS-CRP), and Interleukin-6 (IL-6) reduced following dialysate cooling, whereas serum albumin rose. In the control group, IL-6 dropped but serum ferritin, TSAT, albumin, and HS-CRP rose. In both groups, hemoglobin levels dropped, and erythrocyte sedimentation rate (ESR) rose, both groups' midarm muscle circumference and MIS worsened. CONCLUSION: Cold dialysate decreased intradialytic hypotension with no significant improvement of the nutritional and inflammatory surrogates. However, more studies including larger number of patients with longer duration of follow up are required to adequately assess its effect on inflammation and nutrition in chronic hemodialysis patients.

Symptom burden, fatigue, sleep quality and perceived social support in hemodialysis patients with musculoskeletal discomfort: a single center experience from Egypt.

BACKGROUND AND AIMS: Musculoskeletal disorders (MSDs) are commonly encountered in hemodialysis (HD) patients. However, the causes linked to these disorders are still partially defined. The aim of this study was to determine the frequency of MSDs and their relationship to a variety of clinico-social characteristics such as sleep quality, mood disorders, fatigue, and social support, in addition to the patients' clinical and therapeutic profile. METHOD: The study included 94 patients on maintenance HD. Clinical and Sociodemographic data was gathered. To investigate the prevalence and trends of MSDs, the Nordic Musculoskeletal Questionnaire (NMQ-E) was employed. Patients completed the modified Edmonton Symptom Assessment System, Pittsburgh Sleep Quality Index (PSQI), multidimensional Fatigue Inventory (MFI-20), and Perceived Social Support from Family Scales. Univariate and multivariate regression analysis were used to assess the determinants of MSDs. RESULTS: The patients' mean age was 49.73 and 59.6% were males. Seventy-two percent of patients were afflicted by MSDs. Knee pain (48.9%), low back pain (43.6%), shoulder pain (41.6%), hip/thigh pain (35.1%), and neck pains (35.1%) were the most reported MSD domains. Pain (p = 0.001), fatigue (p = 0.01), depression (p = 0.015), and anxiety (p = 0.003) scores were substantially higher in patients with MSDs. Furthermore, patients with MSDs engaged in less physical activity (p = 0.02) and perceived less social support (p = 0.029). Patients with MSDs had lower subjective sleep quality, daytime dysfunction domains, and global PSQI scores (p = 0.02, 0.031, 0.036, respectively). Female gender (p = 0.013), fatigue (p = 0.012), depression (p = 0.014), anxiety (p = 0.004), lower activity (p = 0.029), and PSQI score (0.027), use of erythropoiesis-stimulating agents (ESAs), antihypertensive drugs, calcium and Iron supplementation were all significantly associated with MSDs. At the multivariable regression model, administration of ESAs (p = 0.017) and pain score (p = 0.040) were the only independent variables associated with the outcome. CONCLUSION: MSDs are quite common among HD patients. Female gender, pain, fatigue, depression, anxiety, reduced activity, poor sleep quality, and use of ESAs are all significantly associated with MSDs in HD patients. Patients with MSD perceived less social support compared to the other group. Patients treated with antihypertensive drugs, calcium and iron supplements were more likely to suffer MSDs.

Clinical and Ultrasonographic Characteristics of the Achilles Tendon in Hemodialysis Patients.

Background and Objectives: The early recognition of tendon alterations in chronic hemodialysis (HD) patients, an awareness of the factors that influence the condition, and active intervention have considerable clinical relevance. The aim of this study was to investigate the musculoskeletal ultrasound (MSUS) features of the Achilles tendon in chronic HD patients and determine the factors associated with tendon abnormalities. Materials and Methods: This study was conducted on 46 HD patients and 24 sex- and age-matched controls. All participants were evaluated clinically for any signs of Achilles tendon abnormalities. Then, the Achilles tendon was scanned bilaterally using MSUS. Results: Among the 92 Achilles tendons in the HD patients, there was tenderness and swelling of only two (2.2%). Regarding MSUS features, there were statistically significant higher thicknesses in the proximal end (p < 0.001), midpoint (p < 0.001), and distal end (p < 0.001) of the Achilles tendons in the HD patients when compared with the healthy controls. Tendinosis was found in 12 (13%) of the HD patients' Achilles tendons, which was statistically significant in comparison to the healthy controls (p = 0.008). There were statistically significant higher scores of structural abnormalities (p = 0.005), bone erosions (p = 0.017), and calcifications (p = 0.015) in the HD patients when compared to the healthy controls. According to the results of a univariate regression analysis, age and male gender were predictive for US abnormalities in HD patients (p = 0.002 and 0.025, respectively). Conclusions: The Achilles tendon in subjects on chronic HD showed frequent US abnormalities. These abnormalities in HD patients appear to be more related to age and gender and may be asymptomatic.

Tixagevimab and Cilgavimab (Evusheld) Boosts Antibody Levels to SARS-CoV-2 in End-Stage Renal Disease Patients on Chronic Hemodialysis: A Single-Center Study.

Background and Objectives: In addition to a suboptimal and rapidly diminishing response to the coronavirus disease 2019 (COVID-19) vaccine, hemodialysis (HD) patients are at risk for developing a severe COVID-19 infection. In 2022, the combination of cilgavimab and tixagevimab (Evusheld, AstraZeneca) was approved for COVID-19 preexposure prophylaxis in high-risk groups. The purpose of this study was to evaluate the humoral response and short-term safety of this antibody combination in a group of HD patients. Materials and Methods: Seventy-three adult maintenance hemodialysis patients were recruited from a tertiary-care hospital for this double-blinded, non-randomized, placebo-controlled study. Patients were placed into two groups: the intervention group (n = 43) received a single 300 mg dosage of cilgavimab and tixagevimab, while the control group (n = 30) received a saline placebo. The titer of COVID-19-neutralizing antibodies was measured at baseline and after 1 and 6 months. The patients were evaluated for any drug-related adverse effects and monitored for six months for the emergence of any COVID-19-related events. Results: Patients in the intervention group were substantially older and had been on HD for longer (p = 0.002 and 0.006, respectively). The baseline antibody levels were higher in the Evusheld group. The antibody level in the intervention group increased significantly after 1 month and remained consistent for 6 months, whereas the antibody level in the control group fell significantly after 6 months during the study period (Wald χ2 = 30.620, p < 0.001). The drug-related adverse effects were modest and well-tolerated, and only seven patients experienced them. Six months after study enrollment, 10 patients in the intervention group and 6 patients in the control group had been infected with COVID-19, respectively. In the control group, ICU admission and mortality were observed, but in the intervention group, the infection was milder with no aggressive consequences. Conclusions: This study demonstrated the short-term safety and efficacy of tixagevimab-cilgavimab for COVID-19 preexposure prophylaxis in HD patients. These findings require more studies with more HD patients and longer follow-up periods.

COVID-19 Vaccination Intention and Vaccine Hesitancy among Patients with Autoimmune and Autoinflammatory Rheumatological Diseases: A Survey.

Background: Coronavirus disease 2019 (COVID-19) vaccine hesitancy or refusal has arisen as a major global public health concern. The aim of this study was to address the attitudes of patients with autoimmune and autoinflammatory rheumatological diseases (AIIRDs) about COVID-19 vaccination and investigate the factors that influence their decision. Methods: This interview-based cross-sectional study was carried out on AIIRD patients at the period between 15 August and 15 September 2021. The questionnaire included socioeconomic data, intention to receive COVID-19 vaccine, AIIRD subtype, disease duration, associated comorbidities, history of COVID-19, beliefs and attitudes towards COVID-19, and conventional vaccination in general and COVID-19 vaccine in particular, in addition to COVID-19 vaccination status. Results: A total of 206 AIIRD patients were included, with a mean age of 37.61 years (SD = 10.67), and 84% were females. The percentage of vaccine acceptance was 70.39%, while only 16.02% were hesitant and 13.59% were resistant to COVID-19 vaccination. About one-fourth of patients reported getting infected with COVID-19. Of them, 15.1% were hospitalized and 5.7% were admitted at the intensive care unit (ICU). Most of the AIIRD patients (77.2%) believed that they are at a higher risk of getting COVID-19. The main motivation for vaccine acceptance was the fear of being infected (41.4%). About 40% of vaccine nonacceptants fear about the serious side effects of COVID-19 vaccine. Conclusion: There is a high acceptability rate of COVID-19 vaccination among AIIRD patients. Public health workers and policymakers must emphasize efficient COVID-19 vaccine acceptance messaging for all AIIRD patients.

Ultrasound Versus Magnetic Resonance Imaging in the Evaluation of Shoulder Pain in End Stage Renal Disease Patients on Chronic Hemodialysis.

Background: Musculoskeletal pain is common in hemodialysis (HD) patients and may be related to articular or periarticular amyloid deposition. The shoulder is one of the most common afflicted joints, but not all causes of shoulder pain are detectable on radiography, and magnetic resonance imaging (MRI) is not always available. The aim of this study was to evaluate the validity of musculoskeletal ultrasound (MSUS) to properly detect shoulder disorders in HD patients by identifying US abnormalities in the shoulder and comparing them to those identified on MRI, with MRI serving as the gold standard test. Methods: This cross-sectional observational study was conducted on 28 HD patients (16 males and 12 females, mean age 46.89) with either unilateral or bilateral shoulder pain. Demographic data and clinical characteristics were recruited. All patients were subjected to clinical assessment, MSUS and MRI of both shoulders. Results: US abnormalities were prevalent in almost all patients. Supraspinatus tendinopathy was the most common abnormality in symptomatic shoulders (92.1%), followed by subacromial-subdeltoid (SASD) bursitis (65.8%), humoral erosions (57.9%), and acromioclavicular joint (ACJ) osteoarthritis (52.6%). MSUS shows high sensitivity and specificity when compared to MRI in all the studied shoulder pathologies except glenohumeral joint (GHJ) effusion (sensitivity, 33.3%) and infraspinatus tendinopathy (sensitivity, 58.3%). The percentage of agreement between MSUS and MRI in detecting biceps tenosynovitis was 82.14% (kappa, 0.64), subscapularis tendinopathy 83.93% (kappa, 0.654), supraspinatus tendinopathy 91.07% (kappa, 0.617), infraspinatus tendinopathy 82.14% (kappa, 0.470), SASD bursitis 80.36% (kappa, 0.569), humeral head erosions 82.14% (kappa, 0.635), GHJ effusion 82.14% (kappa, 0.352), and ACJ osteoarthritis 76.79% (kappa, 0.539). Conclusions: Shoulder problems are common in HD patients, even in people who do not have obvious shoulder complaints. MSUS is a valuable imaging technique that assists in the diagnosis of HD patients who report shoulder pain.

Attitude towards COVID-19 vaccination among healthcare workers: a cross sectional study from Egypt.

BACKGROUND: Herd immunity is necessary to contain the coronavirus disease 2019 (COVID-19) pandemic. Vaccination is the fastest and safest pandemic control strategy. Healthcare workers (HCWs) are essential in providing vaccination information. The aim of this study was to assess intent to be vaccinated against COVID-19 among HCWs in Egypt and to determine the factors that may influence their decision. METHODS: A questionnaire-based cross-sectional study was conducted among HCWs who care for patients in several hospitals in Delta region, Egypt. The questionnaire included sociodemographic, clinical, and occupational data, intention to receive the COVID-19 vaccine, and beliefs and attitudes towards COVID-19 and its vaccination. RESULTS: The study included 455 HCWs with a mean age of 36.55 years (SD = 10.31) and 80% were females. The acceptance rate for the COVID-19 vaccine was 70.5%, while hesitancy and resistancy were both 17.6 and 11.9% respectively. About one-third (33.4%) of the subjects had previously contracted COVID-19. Most participants believed that they had a higher risk of contracting COVID-19 (71.6%). More than 64% believed they were at risk for vaccination side effects. Fear of infection and being at high risk of infection were the main drivers for COVID-19 vaccination, while the major barriers were waiting for additional experience with these new vaccines and having doubts about the vaccines' efficacy. CONCLUSIONS: The acceptance of the COVID-19 vaccination among HCWs is very high. This crucial group needs to be the focus of educational initiatives and campaigns designed to increase public awareness of the safety and effectiveness of COVID-19 vaccination.

Ultrasonographic assessment of entheseal sites of upper and lower extremities in hemodialysis patients using Madrid Sonography Enthesitis Index.

BACKGROUND: There is no much information about the entheseal involvement among hemodialysis (HD) patients. The aim of this study was to assess the frequency and distribution of ultrasonographic (US) entheseal alterations in HD patients and to evaluate the association between US abnormalities and both clinical and laboratory data. METHODS: This study was conducted on 41 HD patients and 23 sex- and age- matched controls. All participants were evaluated clinically for any signs of enthesopathy. Six entheses sites were scanned bilaterally using grey scale (GS) and power Doppler (PD) US and were scored using Madrid Sonography Enthesitis Index (MASEI) scoring system. RESULTS: In HD patients, at least one clinical sign suggestive of enthesopathy was found in 69 (14%) of 492 entheses. HD patients had statistically significant higher scores of structural tendon abnormalities (p < 0.001), enthesis thickening (p < 0.001), bone erosions (p < 0.001) and calcification (p = 0.037) than the healthy controls. Total MASEI score was higher in HD patients than healthy controls (median;18 vs 8, p < 0.001), also, MASEI-inflammatory (median;11 vs 3, p < 0.001) and damage scores (median;6 vs 0, p < 0.001). There was a statistically significant positive association between total MASEI score and both age (p = 0.032) and duration of HD (p = 0.037). Duration of HD was predictive for both MASEI-damage component (p = 0.004) and total MASEI score (p = 0.014). CONCLUSION: There is a high prevalence of subclinical enthesopathy in HD patients. The entheseal US alterations is much higher in HD patients than in healthy subjects. The duration of HD is the significant predictor of enthesopathy in HD patients.

Challenges of Egyptian patients with systemic lupus erythematosus during the COVID-19 pandemic.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic in Egypt is part of the worldwide COVID-19 pandemic that has contributed to substantial deterioration of healthcare systems. The aim of this study was to assess the challenges faced by Egyptian systemic lupus erythematosus (SLE) patients during the COVID-19 pandemic. MATERIAL AND METHODS: This questionnaire-based study was carried out on 200 patients with SLE from Egypt. The questionnaire provided covered socioeconomic status, lupus disease data, information about COVID-19 infection, and medical and family history of COVID-19 infection. RESULTS: The mean age of the participants was 30.1 ±8.4 years. 140/200 (70%) of the participants reported difficulty in obtaining medications during the COVID-19 pandemic, particularly antimalarials (60%). The lupus disease condition became worse because of the drug shortage in half of the participants. Wearing protective masks (74%) and using disinfectants of the hands several times per day (67%) were the most reported used measures. Forty patients (20%) had to stop or reduce taking nonsteroidal anti-inflammatory drugs while 10 patients (5%) had to start taking antimalarials as a prophylaxis against COVID-19 infection. Among those who needed hospitalization, the main cause was lupus activity, and most of them (71%) experienced difficulty in hospital admission. Thirty-two patients (16%) had confirmed COVID-19 infection. About half of them had lupus flare and had to change the medications used for treatment of lupus. CONCLUSIONS: The current COVID-19 pandemic has a negative impact on the healthcare provided to SLE patients in Egypt. Patients with SLE faced a shortage of their medications, especially antimalarials, and difficulty in hospital admission.

Clinical and histopathological features and short-term outcomes of lupus nephritis: a prospective study of 100 Egyptian patients.

OBJECTIVE: The short-term outcomes of lupus nephritis (LN) are variable and unpredictable among individuals. We aimed to evaluate the clinical and histopathological features and short-term renal outcomes in LN patients. METHODS: This was a prospective cohort study carried out at nephrology and rheumatology units in Egypt between 2018 and 2019. A total of 100 patients with biopsy-proven LN were studied. Patients were evaluated for response after six months. RESULTS: The female-to-male ratio was 8.1:1. About 70% of patients were hypertensive at disease onset, with rates for classes I, II, III, IV, V and VI LN being 1%, 7%, 20%, 53%, 14% and 6%, respectively. Among the immunosuppressive drugs used for induction, mycophenolate mofetil (MMF) represented the most commonly used (44%) followed by cyclophosphamide (CYC; 37%). After six months of follow-up, about two thirds of patients achieved remission. There was no significant difference in remission rate between MMF and CYC. On multivariate analysis, serum creatinine (SCr) at presentation was the most significant predictor of renal recovery. According to the receiver operating characteristic curve, the cut-off value of SCr was 1.6 mg/dL, with a sensitivity of 76% and specificity of 71% predicting renal recovery. Repeat renal biopsy was needed in 10 patients; class and treatment strategy changed in 40% and 70% of them, respectively. CONCLUSION: Our findings in Egyptian LN patients compare favourably with most studies.

Musculoskeletal symptoms and their impact on health-related quality of life in chronic nonbacterial osteomyelitis patients.

INTRODUCTION: Chronic non-bacterial osteomyelitis (CNO) is a rare, non-infection- related inflammatory disorder that affects children and teens. Clinical manifestations of CNO range widely from moderate, time-limited, monofocal inflammation of the bone to extreme multifocal or chronically active inflammation of the bone. OBJECTIVES: The main aim of this study was to explore the correlation between musculoskeletal (MSK) symptoms and health-related quality of life (HRQoL) in patients with CNO. METHODS: Children and adults with CNO and their parents were asked to answer a web-based survey. The survey consisted of multiple questions centered around demographic, clinical and therapeutic data, MSK discomfort form based on the Nordic MSK Questionnaire and HRQoL based on Pediatric Quality of Life Inventory-4 (PedsQL-4) and PedsQL rheumatology module. The inclusion criteria included diagnosis of CNO before the age of 18. Patients who had malignancies or any chronic rheumatic, MSK, neurological disease prior to CNO onset were excluded. RESULTS: There was a total of 68 participants, mostly females (66.2%), with median age 14 years and median disease duration 4.75 years. The median number of bones affected by CNO was 5 and ranged from 1 to 24 bones. Among the studied patients, 45 patients (66.2%) had MSK manifestations at the last month. The most commonly affected part was ankle and feet (26.5%). Regarding HRQoL, patients with MSK manifestations had lower scores than did patients without in PedsQL-4 (p < 0.001) including domains of physical functioning (p < 0.001), emotional functioning (p = 0.033), social functioning (p < 0.001) and school functioning (p = 0.007) in addition to lower scores in PedsQL rheumatology module (p < 0.001) including domains of pain and hurt (p < 0.001), daily activities (p < 0.001), treatment (p = 0.035), worry (p = 0.001) and communication (p < 0.001). CONCLUSION: MSK manifestations have a negative impact on HRQoL in CNO patients. So, early identification and treatment are highly recommended.

Extraarticular manifestations of juvenile idiopathic arthritis and their impact on health-related quality of life.

OBJECTIVES: The objective of this study is to investigate extraarticular manifestations (EAMs) in patients with juvenile idiopathic arthritis (JIA) and assess their impact on health-related quality of life (HRQoL) among these patients. METHODS: This cross-sectional analytic study was carried out on 117 patients with JIA. EAMs were identified clinically by history and examination. Sicca symptoms, peripheral neuropathy, enthesitis, and skin lesions were picked up during clinical examination. Pulmonary involvement was evaluated by high-resolution CT chest. Patients were assessed by abdominal ultrasonography to assess the size of liver and spleen. Atlantoaxial subluxation was evaluated by cervical spine x-rays. Patients were evaluated by Pediatric Quality of Life Inventory-4 (PedsQL-4) and PedsQL-3 arthritis module. RESULTS: The median age of patients was 14 years with a median disease duration 4 years, 82.9% were females. Of the studied 117 JIA patients, 85 patients (72.6%) had at least one EAM. Persistent fatigue (51.3%) was the most prevalent EAM, followed by recurrent skin rash (16.2%), enthesitis (15.4%), recurrent fever (13.7%), and uveitis (12%). Patients with EAMs scored significantly lower in physical functioning (p = 0.001), emotional functioning (p < 0.001), social functioning (p = 0.005), and school functioning (p = 0.001). Regarding PedsQL arthritis module, patients with EAM had also significantly lower scores than did patients without EAM on the domains of pain and hurt (p < 0.001), daily activities (p = 0.008), and worry (p = 0.001). RESULTS: EAMs are prevalent among JIA patients and have a negative impact on their HRQoL. So, early identification and treatment are highly recommended. Key Points • A large percentage of JIA patients experienced at least one extraarticular manifestation (EAM). • Persistent fatigue and recurrent skin rash are the most prevalent EAMs in JIA patients. • JIA patients with EAMs have worse scores in almost all domains of HRQoL.

Seroprevalence of Toxoplasma gondii among hemodialysis patients: A possible link to main T-lymphocyte subsets levels and dialysis adequacy.

BACKGROUND: A high prevalence of Toxoplasma gondii infection has been reported in patients with hemodialysis (HD). However, a lack of data exists on the relationship between T lymphocyte subsets and dialysis adequacy. This study aimed to investigate the seroprevalence of Toxoplasma gondii infection among HD patients and its relation to T lymphocyte cells subsets, CD3+, CD4+, CD8+, CD4+/CD8+ ratio, and HD adequacy. METHODS: This cross-sectional comparative study was conducted on 92 subjects. Of them, 42 HD patients and 50 were control participants. Anti-Toxoplasma gondii IgG, IgM antibodies, the T lymphocyte cells subset CD3+, CD4+, CD8+, CD4+/CD8+ ratio, and adequacy of dialysis via calculation of Kt/V were detected for all subjects. RESULTS: The seropositivity for anti-Toxoplasma gondii IgG antibodies was significantly higher in HD patients 66.7% (28/42) compared to 34% in controls (17/50), (p = 0.0003). The main T lymphocyte subsets was significantly lower in HD compared to controls (p < 0.05). Seropositive HD patients exhibited statistically significantly lower T lymphocyte cell subsets and CD4+/CD8+ ratio compared to seronegative patients (p < 0.05). There was a negative correlation between anti-Toxoplasma gondii IgG level and T lymphocyte subsets and the CD4/CD8+ ratio. Binary logistic regression showed that CD4+ T cell significantly predicts Toxoplasma gondii susceptibility among HD patients (p = 0.03). The mean Kt/V index is significantly lower among seropositive HD patients compared to seronegative HD patients (1.05 ± 0.46, 1.41 ± 0.53, respectively, p = 0.03) with a significant negative correlation with anti-Toxoplasma gondii IgG level (p < 0.05). ROC curve analysis showed the CD4+ T cell % had the highest AUC value among HD patients (AUC= 0.88, p < 0.001). The Kt/V value of ≤ 0.8 significantly predicted susceptibility to Toxoplasma gondii infection among HD patients (AUC = 0.68, p = 0.03). CONCLUSION: The current study reinforces previous reports of a high prevalence of Toxoplasma gondii infection among HD patients. CD4+ T cell and Kt/V showed a good diagnostic performance in predicting susceptibility for Toxoplasma gondii infection in HD patients. Considering the clinical consequences caused by Toxoplasma gondii infection in these patients, regular screening and adequate HD are recommended.

Acceptance and hesitancy to receive COVID-19 vaccine among university students in Egypt: a nationwide survey.

BACKGROUND: The public's willingness to be vaccinated will determine the success of the COVID-19 vaccination program. The aim of this study was to identify acceptance and hesitancy to receive COVID-19 vaccine among university students in Egypt, assess their level of knowledge about COVID-19 vaccine and identify factors that influence their intention towards COVID-19 vaccination. METHODS: A standardized and self-administered questionnaire was distributed among university students allover Egypt. The questionnaire included sociodemographic data, intention to receive COVID-19 vaccine, knowledge and beliefs about it and status of COVID-19 vaccination. Logistic regression analysis was used to determine factors associated with COVID-19 vaccine acceptancy. RESULTS: A total of 1071 of university students were involved, with a mean age of 20.51 years (SD = 1.66) and 68.2% were females. COVID-19 vaccination acceptability rate was 69.0% while hesitancy was 20.8% and resistancy was 10.2%. Median knowledge score of 4 out of 8 (IQR = 8). The main motivation for vaccine acceptance was fear of being infected (53.6%) and desire to get back to normal life (51.0%) while the main barriers against getting vaccinated were being afraid of serious side effects. Univariate regression analysis revealed an increasing likelihood of vaccine acceptancy associated with an active lifestyle (OR 1.35, 95% CI 1.04-1.75, p = 0.025), a high knowledge score (OR 1.53, 95% CI 1.42-1.66, p < 0.001), and positive vaccine beliefs. CONCLUSION: There is a high rate of acceptability of COVID-19 vaccination among university students. Vaccine acceptability is associated with an active lifestyle, a high knowledge score and positive vaccine beliefs. Educational campaigns and efforts aiming to raise awareness about safety and efficacy of COVID-19 vaccines need to be directed to this important population.

Attitudes and concerns regarding booster dose of COVID-19 vaccine among Egyptian patients with autoimmune and rheumatic diseases: a cross-sectional survey study.

BACKGROUND: COVID-19 booster dose vaccination acceptance and actual vaccination behavior is not known among Egyptian individuals with autoimmune and rheumatic diseases (ARDs). The aim of this study was to investigate the acceptability of booster dose of the COVID-19 vaccine, as well as the factors that drive and inhibit that acceptance among Egyptian patients diagnosed with ARDs. METHODS: This interview-based, cross-sectional analytical study was carried out on ARD patients from 20 July to 20 November 2022. A questionnaire was created to assess sociodemographic and clinical data, as well as COVID-19 vaccination status and the intention to receive a COVID-19 vaccine booster dose, perception of health benefits of it in addition to the perceived barriers and/or concerns. RESULTS: A total of 248 ARD patients were included, with a mean age of 39.8 years (SD = 13.2), and 92.3% were females. Among them, 53.6% were resistant to the COVID-19 booster dose, whereas 31.9% were acceptant and 14.5% were hesitant. Those who were administering corticosteroids and hydroxychloroquine shown significantly greater booster hesitancy and resistance (p = 0.010 and 0.004, respectively). The primary motivation for taking a booster dose among the acceptant group was own volition (92%). Most acceptants believed that booster dose can prevent serious infection (98.7%) and community spread (96.2%). Among the hesitant and resistant groups, the main concerns for booster dose were fear about its major adverse effects (57.4%) and long-term impact (45.6%). CONCLUSIONS: There is a low acceptability rate of booster dose of COVID-19 vaccine among Egyptian patients with ARD diseases. Public health workers and policymakers need to make sure that all ARD patients get clear messages about accepting the COVID-19 booster dose.

Anxiety and depression in maintenance hemodialysis patients: prevalence and their effects on health-related quality of life.

PURPOSE: The aims of the study are to explore the prevalence and risk factors of anxiety and depression in hemodialysis (HD) patients and to study their relationship with quality of life (QOL). METHODS: This cross-sectional study involved 298 HD patients. Sociodemographic, clinical, and laboratory data of the patients were obtained from their records. Anxiety and depression were assessed by utilizing Hospital Anxiety and Depression Scale (HADS). In addition, QOL of the patients were evaluated by fulfilling the Kidney Disease Quality of Life-36. RESULTS: This study included 298 HD patients (male 59.1%) with a median age of 49 years. Abnormal and borderline cases of anxiety were recognized in 49.6%, 26.2% of the patients, respectively, while depression cases and borderline cases were identified in 55 and 28.2% of the patients, respectively. Percentages of females (41 and 48% vs 26.4%, respectively), and patients who were not working (92.3 and 93.9% vs 72.2%, respectively) increased significantly in borderline and abnormal anxiety groups. Patients who did not work, led an inactive lifestyle, and smoked had considerably greater percentages in the borderline and abnormal HADS-depression categories than normal patients. Abnormal cases of depression and anxiety had significantly longer duration of HD than other two groups. Abnormal and borderline cases of anxiety and depression had worse QOL components than the normal patients. CONCLUSION: Anxiety and depression are prevalent among HD patients in Egypt, and several sociodemographic and clinical risk factors are associated. In addition, these mental disorders are associated with poor QOL.

Lifting the Mask on Musculoskeletal Manifestations of COVID-19: Results of an Interview-Based Study.

Background: Coronavirus disease of 2019 (COVID-19) is considered a multi-system disease that might present with or develop complications during the acute phase of illness. The aim of this study was to describe the characteristics of musculoskeletal (MSK) manifestations in patients with COVID-19 infection and investigate their clinical correlations. Methods: This study was carried out on 110 patients with a history of RT-PCR confirmed COVID-19 infection. They completed a questionnaire that covered detailed information on their sociodemographic characteristics, clinical data of COVID-19 infection in addition to MSK discomfort form based on the Nordic MSK Questionnaire. Results: The mean age of the patients was 37.7 years (SD 12.9), 72.7% were females. The majority of patients (90.9%) reported MSK symptoms that occur during or shortly after the acute attack of COVID-19 infection. The median duration of onset of MSK symptoms was 2 days from the first day of COVID-19 infection (min-max: 0-45 days) with a median duration of MSK symptoms of 7 days. Myalgia was the main complaint (85.5%) followed by arthralgia 90 (81.8%). However, swollen joints were reported in only 9 patients (8.2%). According to the body areas, maximum number of patients felt pain at the lower back (60%), followed by neck (39.1%), and upper back (32.5%) followed by right and left shoulder (20.9%). Patients with MSK manifestations were associated higher severity of COVID-19 infection (p < 0.001), prolonged duration of COVID-19 symptoms (p < 0.001) and higher prevalence of fatigue (p < 0.001). Conclusion: MSK manifestations are common in COVID-19 patients and related to disease severity, duration and fatigue.

Acceptance of COVID-19 vaccination among maintenance hemodialysis patients: an Egyptian survey study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a contagious disease that is associated with significant morbidity and mortality especially among maintenance hemodialysis (MHD) patients. COVID-19 vaccination is important to decrease risk and severity of COVID-19 infection. However, vaccine hesitancy is a significant barrier to vaccination. Thus, the aim of this study was to investigate the vaccine acceptability among Egyptian MHD patients. METHODS: We conducted a paper-based survey on 237 MHD patients in 2 tertiary Egyptian hemodialysis (HD) centers. The survey consisted of a questionnaire that addressed demographic and clinical data, knowledge and attitudes towards COVID-19 infection and vaccines, beliefs regarding both conventional and COVID-19 vaccines, intention of COVID-19 vaccination together with motivators for and barriers against vaccination, sources of information regarding COVID-19 vaccines. RESULTS: According to intention to be vaccinated, the patients were divided into vaccine acceptant (VA), hesitant (VH), and resistant (VR) groups who comprised 58.3%, 26.5%, and 15.2%, respectively. Only occupational status and residency were significantly different between the three groups. In 60% of VA group, fear of infection was the main motivator for vaccination. Meanwhile, 40% of VH and VR groups reported that fear of serious side effects of vaccines was the main barrier against vaccination. Television was the primary information source (58.6%) about COVID-19 vaccination while only 18% of patients got their COVID-19 vaccine information from their nephrologists. CONCLUSIONS: More than half of MHD patients accept to receive COVID-19 vaccine. Vaccine acceptability is not associated with age, gender, educational level, but rather with employment status and residency.

COVID-19 Vaccination Trends and Side Effects among Egyptian Hemodialysis Patients: A Multicenter Survey Study.

(1) Background: Vaccination may be a key intervention to prevent infection in chronic hemodialysis (CHD) patients. This study aimed to determine the COVID-19 vaccination status in Egyptian CHD patients and to analyze the safety and detailed side effect profile of the COVID-19 vaccine among these patients. (2) Methods: This survey-based study was conducted on 670 end-stage renal disease (ESRD) patients on CHD from 3 December 2021 to 5 February 2022. Subjects were asked about sociodemographic characteristics, clinical and therapeutic data, in addition to their COVID-19 vaccination status. If the subject had been vaccinated, we inquired about the type of vaccine and the side effects that occurred within a few days after administration of the first and second dose of the COVID-19 vaccine. Additionally, subjects were asked about the onset of side effects (days from vaccination), timing of maximum symptoms, intensity of symptoms and their effect on activity and need for medical attention. (3) Results: The study included 670 CHD patients with a mean age of 50.79 years; 58.1% were females. The vast majority (614; 91.6%) of the studied patients received two doses of the vaccine. Side effects were more commonly reported after the first dose than the second dose. The main side effects reported were generalized weakness/fatigue (56%), headache (43.8%) and fever (40.4%), and sore arm/pain was also reported (29.3%). Adverse events mostly occurred within one day after vaccination and the maximum symptoms usually happened on the second day. The median duration of symptoms was 3 days with a maximum duration up to 5 days. The univariate logistic regression analysis showed that male gender (OR 1.848; (95% CI, 1.242−2.749), p = 0.002), age (OR 0.981; (95% CI, 0.969−0.993), p = 0.003), smoking (OR 6.067; (95% CI, 3.514−10.475), p < 0.001), duration since starting HD (OR 0.998; (95% CI, 0.998−0.999), p < 0.001), associated comorbidities (OR 2.202; (95% CI, 1.478−3.281), p < 0.001) and prior COVID-19 infection (OR 3.318; (95% CI, 1.952−5.642), p < 0.001) were the main determinants of adverse events related to COVID-19 vaccination. (4) Conclusions: our preliminary findings support the favorable short-term safety profile of the COVID-19 vaccine among CHD patients, and hence can reassure both clinicians and patients, as well as further promote COVID-19 vaccine administration among these patients.
