Radiation-Induced Macrovessel/Microvessel Disease.

Radiation therapy (RT) is a cornerstone in cancer treatment (used in 50% of cases), yet challenges persist because damage to normal tissue through direct impact of radiation or bystander effects is inevitable. Injury of macrovessels by RT manifests as obstructive disease, which is akin to atherosclerotic disease. Historically observed in coronary arteries of patients treated for breast cancer and lymphoma, it also affects patients receiving contemporary therapy for lung and chest cancers. Moreover, radiation at various sites can lead to peripheral vascular disease. An aspect of radiation-induced injury that has received little attention is microvascular injury, which typically results from damage to the endothelium and is considered the primary driver of RT-induced toxicity in the skin, kidney, and brain. This review delves into the clinical manifestations of RT-induced vascular disease, signaling pathways, cellular targets affected by radiation injury, and preclinical models of RT-induced vascular injury. The goal is to inspire the development of innovative strategies to prevent RT-related cardiovascular disease.

Innate immune response in COVID-19: single-cell multi-omics profile of NK lymphocytes in a clinical case series

BackgroundCOVID-19 pandemic caused by the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) represents the biggest global health emergency in recent decades. The host immune response to SARS-CoV-2 seems to play a key role in disease pathogenesis and clinical manifestations, with Natural Killer (NK) lymphocytes being among the targets of virus-induced regulation.MethodsThis study performed a single-cell multi-omics analysis of transcripts and proteins of NK lymphocytes in COVID-19 patients, for the characterization of the innate immunological response to infection. NK cells were isolated from peripheral blood samples collected from adult subjects divided into 3 study groups: (1) non-infected subjects (Naïve group, n = 3), (2) post COVID-19 convalescent subjects (Healed group, n = 3) and (3) patients that were vaccinated against SARS-CoV-2 (Vaccine group, n = 3). Cells were then analysed by the BD Rhapsody System for the single-cell multi-omics investigation of transcriptome and membrane proteins.ResultsThe bioinformatic analysis identified 5 cell clusters which differentially expressed gene/protein markers, defining NK cell subsets as “Active NK cells” and “Mature NK cells”. Calculating the relative proportion of each cluster within patient groups, more than 40% of the Naïve group cell population was found to belong to Mature NKs, whereas more than 75% of the Vaccine group cell population belonged to the cluster of Active NKs. Regarding the Healed group, it seemed to show intermediate phenotype between Active and Mature NK cells. Differential expression of specific genes, proteins and signaling pathways was detected comparing the profile of the 3 experimental groups, revealing a more activated NK cell phenotype in vaccinated patients versus recovered individuals.ConclusionsThe present study detected differential expression of NK cell markers in relation to SARS-CoV-2 infection and vaccine administration, suggesting the possibility to identify key molecular targets for clinical-diagnostic use of the individual response to viral infection and/or re-infection.

Public Awareness of the Symptoms and Risk Factors of Thyroid Disease in Saudi Arabia.

Thyroid disorders are a common manifestation of hormonal disorders that result from either excessive or insufficient production of thyroid hormones and the swelling of the thyroid gland. A lack of information and awareness of the signs and risk factors of thyroid problems can lead to untreated patients, thereby harming public health. Observational cross-sectional research was conducted in the Al-Baha region of Saudi Arabia, with 531 residents selected from the general population. The data were analyzed using SPSS to derive significant insights, and questionnaires were used to collect the data. The results revealed that 79 (14.9%) of the participants had been diagnosed with thyroid disease. The risk factors for thyroid diseases reported were as follows: female gender (386, 72.7%); exposure to radiation (329, 62.0%); smoking (312, 58.8%); family history (300, 56.5%); and insufficient or excess intake of iodine (277, 52.2%).Only 110 (20.7%) of the participants knew that the use of amiodarone medication is a risk factor for thyroid diseases. The symptoms reported included fatigue (430, 81.0%), feeling cold, and weight gain (409, 77.0%); neck lump (379, 71.4%); depression (367, 69.1%); and hair loss (336, 63.3%). Early diagnosis (426, 80.2%), a well-exercised program (394, 74.2%), and a well-balanced diet (392, 73.8%) were the prevention methods reported by a majority of the participants. The study results revealed an average score of 13.57±2.11, with a minimum knowledge score of 0 and a maximum of 25. A statistically significant difference was observed in knowledge scores based on the participant's gender, age, education level, previous diagnosis with thyroid diseases, family history of thyroid diseases, and having performed thyroid gland investigation with p-values <0.05 (<0.001, 0.019, 0.027, <0.001, 0.023, and 0.031), respectively. Nearly half of the participants had low knowledge scores regarding the risk factors and clinical manifestations of thyroid diseases. Although a sizable proportion of participants demonstrated awareness of some clinical presentations and prevention methods, there are serious knowledge gaps regarding the risk factors and symptoms of thyroid disease among the general population in the Al-Baha region. There is a need for targeted health education programs to improve public awareness of risk factors and early detection and prevention measures of thyroid diseases to improve the quality of life among community members.

Correlation between dental symptoms and functional and clinical manifestations of Crohn's disease and ulcerative colitis

Objective. To analyze the correlation between dental symptoms and clinical and functional manifestations of Crohn's disease (CD) and ulcerative colitis (UC). Materials and methods. A prospective, observational, longitudinal clinical study of 70 patients with verified inflammatory bowel diseases, i.e. Crohn's disease and ulcerative colitis, has been performed. For an in-depth assessment of the oral mucosa (OM) and red lip border (RLB) condition in patients with these systemic diseases, a complete dental examination has been carried out. The validated questionnaire "7´7" was used to objectify the symptoms of functional gastric dyspepsia. Results. In patients with the main clinical manifestations of the gastrointestinal tract impairments in CD and UC, extraintestinal dental manifestations in the form of meteorological cheilitis (16 and 9, respectively; p = 0.081), glossitis (15 and 11, respectively; p = 0.323), onset of recurrent aphthous stomatitis (17 and 11; p = 0.144), chronic mechanical trauma of oral mucosa (14 and 11; p = 0.455), and the presence of scalloped tongue (28 and 21, p = 0.068) were diagnosed. At the same time, the incidence of associated pathologies of OM and RLB was significantly higher in patients with CD (p0.05) than in patients with UC. Clinical examination of patients revealed predominance of flatulence symptoms in patients with CD and UC in 74.3 and 77.1 % of cases, respectively (р = 0.771). Patients with CD prevailed in the number of dyspeptic disorders and their variability but statistically significant differences were determined only for the symptom 'abdominal pain decreasing after bowel emptying'. The correlation between the frequency of dyspeptic disorders in patients and characteristic changes in the clinical state of RLB and OM was revealed. For the CD and UC groups Chuprov conjugacy coefficients were statistically significant (ChC=0.36, ChC=0.28 respectively). In patients with CD clinically apparent changes in the RLB and OM associated with various dyspeptic disorders were manifested more often than in patients with UC. Conclusion. The conducted study has shown that in patients with CD and UC there is a correlation between the frequency and severity of the main functional and clinical symptoms/syndromes (in the form of edema, hyperemia, pitting edema of the ОМ (in fact) and the RLB) and dyspeptic disorders, this correlation being stronger in Crohn's disease (p = 0.031 vs p = 0.046).

Differential T follicular helper cell phenotypes distinguish IgE-mediated milk allergy from eosinophilic esophagitis in children

IgE-mediated food allergy and eosinophilic esophagitis (EoE) are diseases commonly triggered by milk. Milk-responsive CD4+ T cells producing type 2 cytokines are present in both diseases, yet the clinical manifestation of disease in milk allergy (MA) and EoE are distinct. To identify CD4+ T cell differences between EoE and MA that may be responsible for distinct disease manifestations. The total and milk-specific CD4+ T cell phenotype of children with milk allergy (MA), EoE (active or in remission) and controls was measured using spectral flow cytometry of peripheral blood (all groups) or esophageal biopsies (EoE and control). Circulating milk-responsive T cells could be identified in active (A)-EoE and MA. An increased frequency of Th2A cells was also noted in MA and EoE. In circulating T cells, type 2 cytokine production was elevated in MA, but not EoE. Within the milk-responsive Tfh subset, a dichotomy of phenotype was noted: Tfh13 cells predominated in MA, while IL-10-producing Tfh cells predominated in EoE. In the esophagus, CD4+ T cells were constitutively activated and expressed not only type 2 cytokines, but also IL-10 and IL-21 in A-EoE. There was production of IgG4 from CD38+ plasma cells in close proximity to CD4+ T cells. In vitro activation studies demonstrated that IL-10 and IL-21 elicited strong IgG4 responses in B lymphocytes, while IL-4 and IL-13 promoted IgE production. Our studies demonstrate a dichotomy of Tfh responses that may be the basis for the different clinical manifestations to milk in EoE and MA.

Catatonia and neurocognitive disorder in the context of schizophrenia spectrum disorders

Background. Currently, researchers are aiming to establish the relationship between neurocognitive disorder and other clinical manifestations of endogenous diseases and functional indicators of the patient’s adaptation to social life. According to some data, the development of cognitive disorders is associated with the severity of catatonic disorders in the clinical picture of various diseases, in particular the presence of catatonic symptoms determines the worst indicators of cognitive functioning in the case of schizophrenia.The aim. To study the clinical and psychopathological features of catatonic syndrome in connection with schizophrenia spectrum disorders, as well as its connection with neurocognitive disorder manifestations among patients with endogenous disorders.Methods. From September 2022 to March 2024, we conducted a prospective, multicenter study of patients (n = 69) suffering from paroxysmal schizophrenia with primary catatonic symptoms in the structure of attacks. Mental status, the severity of catatonic symptoms using Bush – Francis Catatonia Rating Scale, neurocognitive profile using a number of validated scales (Montreal Cognitive Scale, Brief Assessment of Cognition in Schizophrenia, Frontal Assessment Battery) were assessed.Results. Neurocognitive disorder was revealed in all cases studied. It has been noted that, depending on the presence/absence of affective symptoms, various domains of the neurocognitive profile are affected. Thus, in patients without severe affective symptoms, auditory and verbal memory, attention, processing speed, and motor skills are impaired. In patients with pronounced affective disorders, processing speed, motor skills, and problem-solving behavior are affected.Conclusion. Based on the results of processing the material, it was revealed that the most pronounced neurocognitive disorders were found in case of the manifestation of paroxysmal paranoid schizophrenia in male patients with a relatively early onset of the disease and hypokinetic catatonic disorders. In the future, we are planning to compare these results with the results of control group of patients with endogenous diseases and without catatonia.

Dermatological manifestations, and drug-induced reactions in COVID-19 patients: an observational study from İstanbul, Turkiye

Aims: The systemic and respiratory clinical manifestations of coronavirus disease 2019 (COVID-19) include fever, cough, sneezing, sore throat, rhinitis, dyspnoea, chest pain, malaise, fatigue, anorexia, and headache. Moreover, cutaneous manifestations have been observed in 0.2% to 20.4% of cases. This investigation further explores the dermatological manifestations associated with COVID-19 and reactions induced by its pharmacological treatments. Conducted at a university hospital, the study examined 841 patients and identified skin manifestations in 1.5% of cases. It differentiates between symptoms directly attributed to the viral infection and those arising from treatment, highlighting the need for clinical vigilance and adaptability in managing these manifestations. COVID-19 has been linked to a wide range of clinical symptoms, extending beyond the well-known respiratory effects to include various dermatological manifestations. These manifestations, which range from mild rashes to severe conditions like vasculitis, may complicate diagnosis and management, particularly when similar symptoms are induced by therapeutic drugs used in COVID-19 treatment. Methods: This cross-sectional study included 841 patients treated in the COVID-19 outpatient and inpatient units of the university hospital between March and May 2020. The assessment involved clinical examinations and telemedicine consultations, focusing on differentiating between viral and drug-induced dermatological reactions. Results: Dermatological manifestations were observed in 1.5% of the 841 patients. Direct virus-related skin changes were noted in 1% (n=8) of patients, including maculopapular eruptions (50%, n=4) on the face and trunk, trunk-localized urticaria (25%, n=2), and purpuric lesions (12.5%, n=1) on the lower extremities. Drug-induced dermatological reactions were identified in 0.5% (n=5) of patients, featuring conditions such as bullous drug reactions, psoriasiform drug eruptions, hypertrichosis, and urticaria. Conclusion: These findings highlight the complex interplay between COVID-19 and its treatment, where both the virus and pharmacological agents can trigger significant dermatological reactions. The need for healthcare providers to consider both viral and drug-induced factors in the diagnosis and management of skin manifestations in COVID-19 patients is underscored. Further studies are essential to refine treatment protocols and reduce adverse dermatological outcomes.

Clinical and immunological characteristics of post-covid patients with infectious immunopathology syndrome

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has caused global morbidity and high mortality worldwide. Today it is known that, despite recovery from COVID-19, confirmed by both laboratory and instrumental diagnostic methods, many patients, regardless of the severity of the disease, suffer from a significant deterioration in health and increased exacerbations of chronic diseases. During examinations by attending physicians, they note fatigue, an increase in cases of acute respiratory viral infections per year, an increase in relapses of skin diseases such as furunculosis, pyoderma, exacerbation of pulmonary pathologies, pathologies of the urinary tract of inflammatory origin, as well as chronic infectious diseases such as herpesvirus and human papillomavirus infections, which occur for the first time or are characterized by frequent relapses no less than six months after recovery from acute COVID-19. Such persistent post-infectious consequences are known as post-COVID syndrome. SARS-CoV-2 infection is accompanied by damage to both the acquired and innate immune systems. In previous work, we determined the role of B cells, cytotoxic T lymphocytes, natural killer cells and the regulatory properties of CD46, as well as its involvement in the processes of viral entry into the cell. In this study, we studied the relationship of immune disorders of these factors of innate and acquired immunity with the clinical manifestations of post-COVID infectious syndrome in this category of patients and the severity of lung damage in these patients during the acute period of COVID-19. The results of the study showed that in some patients more than six months after suffering from COVID-19, the following was revealed: in patients who had a coronavirus infection without lung damage, no violations of the innate and acquired parts of the immune system were detected. In addition, significant differences were identified between clinical manifestations of diseases with increasing cases of relapses or newly identified after clinical recovery from an acute COVID-19 infection, depending on the phenotype of immune status disorders.

Determination of antinuclear antibodies: role in modern differential diagnosis of connective tissue autoimmune diseases

There is an increase in autoimmune rheumatic diseases among all age population groups globally. Diagnosis is often difficult, because the early stages of the diseases usually do not have specific symptoms. Often, clinical manifestations of autoimmune diseases and non-autoimmune pathologies have similar symptoms. Therefore, the differential diagnosis could be very difficult. Most often, the determination of antinuclear autoantibodies is used for laboratory diagnosis of connective tissue systemic diseases. Autoantibodies can be detected in patients long time before the appearance of symptoms. The correct diagnosis is very important because the therapy of various nosologies can be different. It is especially significant with the invention of targeted therapy. Further analysis of the diagnostic value of autoantibody determination is very important. This article presents examination and follow-up data of three children. The analysis of medical documentation was carried out. The role of determining autoantibodies in the differential diagnosis of autoimmune connective tissue diseases was analyzed. In the first patient with Sjögren’s syndrome, the clinical picture of the underlying disease developed at least 5 years after the detection of high levels anti-SS-A, SS-B and Ro-52 antibodies (immunoblotting) and the speckled pattern (indirect immunofluorescence assay). In the second patient, antibodies against centromeres (specific markers of systemic scleroderma) appeared at least 2 years before clinical symptoms. In the third patient, the specific markers of systemic scleroderma have been detected for 5 years. There were antibodies against centromeres (immunoblotting), high titer and the centromere pattern (indirect immunofluorescence assay). However, the patient has not developed any clinical symptoms of this disease during all time of observation. Thus, the analysis of the presented clinical cases shows that autoantibodies can be detected in patients long time before the onset of clinical manifestations of a specific autoimmune disease. In all three cases, the first immunological examination has been carried out in the background of the disease symptoms, but they were atypical. Identification of specific autoantibodies, is very important for differential diagnosis. In the absence of clinical symptoms, the presence of autoantibodies, is the reason for dynamic observation of the patients.

Why is vestibular migraine associated with many comorbidities?

Vestibular migraine (VM) is a usual trigger of episodic vertigo. Patients with VM often experience spinning, shaking, or unsteady sensations, which are usually also accompanied by photophobia, phonophobia, motor intolerance, and more. VM is often associated with a number of comorbidities. Recurrent episodes of VM can affect the patient's emotions, sleep, and cognitive functioning to varying degrees. Patients with VM may be accompanied by adverse moods such as anxiety, fear, and depression, which can gradually develop into anxiety disorders or depressive disorders. Sleep disorders are also a common concomitant symptom of VM, which significantly lower patients' quality of life. The influence of anxiety disorders and sleep disorders may reduce cognitive functions of VM, such as visuospatial ability, attention, and memory decline. Clinically, it is also common to see VM comorbid with other vestibular disorders, making the diagnosis more difficult. VM episodes are relieved but lingering, in which case VM may coexist with persistent postural-perceptual dizziness (PPPD). Anxiety may be an important bridge between recurrent VM and PPPD. The clinical manifestations of VM and Meniere's disease (MD) overlap considerably, and those who meet the diagnostic criteria for both can be said to have VM/MD comorbidity. VM can also present with positional vertigo, and some patients with VM present with typical benign paroxysmal positional vertigo (BPPV) nystagmus on positional testing. In this paper, we synthesize and analyze the pathomechanisms of VM comorbidity by reviewing the literature. The results show that it may be related to the extensive connectivity of the vestibular system with different brain regions and the close connection of the trigeminovascular system with the periphery of the vestibule. Therefore, it is necessary to pay attention to the diagnosis of comorbidities in VM, synthesize its pathogenesis, and give comprehensive treatment to patients.

IgG4-Related Disease: Comprehensive Overview of Pathogenesis, Clinical Manifestations, and Diagnostic Challenges.

Introduction IgG4-related disease (IgG4-RD) is a progressive and potentially life-threatening condition characterized by immune system activation and tissue fibrosis, affecting various organs such as the pancreas, kidneys, and lungs. Initially recognized in 2003, it often presents as mass-like lesions, which can mimic tumors. Despite advancements in understanding its pathology, epidemiological data are limited, and many patients remain undiagnosed due to unfamiliarity with the disease. Aim of the study The aim of this article wast to summarize the latest knowledge on the diagnosis and clinical manifestations of IgG4-related disease. Materiał and methods This review is based on articles from the PubMed and Google Scholar databases, covering the years 2007-2024, using the keywords: IgG4-related disease; autoimmune pancreatitis; retroperitoneal fibrosis; classification criteria. Results The disease's complex pathogenesis involves B and T cell activity, with genetic and environmental factors contributing. While effective treatments, like B cell depletion, exist, the disease's broad clinical manifestations and multi-organ involvement require a multidisciplinary approach for proper diagnosis and management. Conclusion Diagnosing IgG4-RD is challenging due to its varied symptoms, often mimicking other diseases. Key findings include high IgG4 levels and specific histopathological features. Further research is needed to understand its genetic factors, pathogenesis, and epidemiology.

Risk of incident chronic obstructive pulmonary disease during longitudinal follow-up in patients with nontuberculous mycobacterial pulmonary disease

BackgroundThe Global Initiative for Chronic Obstructive Lung Disease 2023 revision proposed that chronic obstructive pulmonary disease (COPD) has various etiologies including infections (COPD-I), such as tuberculosis and human immunodeficiency virus. While nontuberculous mycobacterial pulmonary disease (NTM-PD) and pulmonary tuberculosis share similar clinical manifestations, research on COPD development during longitudinal follow-up in patients with NTM-PD is limited. In this study, we aimed to evaluate the incidence and risk of COPD development in patients with NTM-PD.MethodsWe retrospectively enrolled patients with NTM-PD with normal lung function and 1:4 age-, sex-, body mass index-, and smoking status-matched controls between November 1994 and January 2022. We compared the risks of spirometry-defined COPD between the NTM-PD and control groups (study 1). A nationwide cohort study using the health insurance claims database was conducted to validate the findings (study 2).ResultsIn study 1, during a mean follow-up of 3.3 years, COPD occurred in 14.0% (241/1,715) and 4.3% (293/6,860) of individuals in the NTM-PD and matched control cohorts, respectively. The NTM-PD cohort exhibited a higher risk of incident COPD (adjusted hazard ratio [aHR], 2.57; 95% CI, 2.15–3.09) compared to matched controls. In study 2, COPD occurred in 6.2% (24/386) and 2.5% (28/1,133) of individuals with and without NTM-PD, respectively. The NTM-PD cohort had a higher risk of incident COPD (aHR, 2.04; 95% CI, 1.21–3.42) compared to matched controls.ConclusionThese findings suggest that NTM-PD could be considered a new etiotype of COPD-I and emphasize the importance of monitoring lung function in individuals with NTM-PD.

Pylore Krishnaier Rajagopalan: Pioneer in Kyasanur Forest Disease Research and His Contributions to Zoonotic Disease Studies.

Pylore Krishnaier Rajagopalan was a distinguished public health expert who made significant breakthroughs in the research of Kyasanur forest disease (KFD), a prevalent tick-borne viral ailment in South India. His extensive research on KFD provided vital insights into the impact of the disease on public health and considerably advanced our knowledge of it. Rajagopalan's work also encompasses the study of zoonotic diseases, where he made substantial contributions to our understanding of their epidemiology and control. His research on KFD was instrumental in comprehending the disease transmission dynamics, clinical manifestations, and control strategies, resulting in improved management practices in regions where the disease is endemic. Rajagopalan's contributions have had a long-lasting impact on public health practices, as his work has influenced both scientific research and public health policies. The enduring effects of his work can be observed in the enhanced disease surveillance, outbreak response, and comprehension of zoonotic disease dynamics, which will continue to inform contemporary public health practices.

Quality assessment of heatstroke videos on TikTok.

The prevalence of heatstroke is rising due to global warming, making it a serious but preventable condition, highlighting the urgent need for effective dissemination of relevant health education to the general public. Advances in technology have made accessing health information more convenient and rapid. In recent years, short videos have become a primary medium for delivering health education, with TikTok gaining considerable popularity among the general public. However, the quality of heatstroke-related health education content on TikTok deserves closer scrutiny. This study aimed to evaluate the quality and content of heatstroke-related videos available on TikTok. The present study analyzed the top 100 heatstroke-related short videos on TikTok, focusing on their characteristics, quality, and the content they conveyed. The quality of these videos was assessed using the DISCERN instrument. In addition, the completeness of the videos was assessed by examining six key aspects: disease definition, clinical manifestations, risk factors, assessment, management, and outcomes. The study included a total of 90 videos. The results showed that news organizations and healthcare professionals were the primary contributors to these videos, with those from news organizations receiving the most attention. In contrast, those from healthcare professionals received comparatively less engagement. Overall, the quality of the information was found to be moderately low, with the highest quality videos posted by non-profit organizations, followed by those posted by healthcare professionals. The majority of videos uploaded described the disease definition, clinical presentation, risk factors, assessment, management, and outcomes of heatstroke. The quality of information provided in heatstroke-related short videos on TikTok is generally inadequate and requires significant improvement. In addition, such content should be subject to government review to ensure its accuracy and reliability.

A rare deleterious case of concomitant renal disease associated with IgG4-associated systemic disease

In IgG4-associated disease, several organs and tissues are often affected, especially kidney tissue, and is characterized by interstitial nephritis, obstructive nephropathy, and in rare cases glomerulopathy (including membra[1]nous nephropathy).IgG4-associated disease was isolated as an independent nosological form in 2003, when patients with type 1 autoimmune pancreatitis were found signs of systemic damage (involvement of the biliary tract, salivary glands, retroperitoneal space), and in 2012 the first international nomenclature of the disease was proposed.The clinical manifestations of IgG4-associated disease are nonspecific and diverse, which determines the difficulties of differential diagnosis, including infections and tumors, and increases the period from the onset of the disease to diagnosis to an average of 2 years. IgG4-associated disease is more likely to develop in middle age and old age. The prevalence of the disease is higher among men than among women. Thus, autoimmune pancreatitis type 1, retroperitoneal fibrosis and tubulointerstitial nephritis are more common in men, and sialoadenitis, dacryoadenitis and thyroiditis are more common in women.In this article, we present a clinical case of IgG4-associated systemic disease with a combined lesion of the tubulo-interstitial and glomerular compartments of kidney tissue with nephrotic syndrome as the only initial manifestation. The combination of IgG4-tubulo-interstitial nephritis with membranous nephropathy is an ex[1]tremely rare pathology. Nephrobiopsy was crucial in the diagnosis of this condition, which allowed the patient to be prescribed proper and timely treatment.

Evolving Pattern of Human Cystic Echinococcosis: A Cross-Sectional Study

Introduction Cystic echinococcosis (CE) poses a considerable public health challenge in many countries. Due to the absence of comprehensive CE surveillance and management guidelines and varying demographic and geographical factors across countries, examining the disease's epidemiology and clinical manifestations within specific regions is essential. The current study aims to investigate CE trends, clinical features, and patient complaints in an endemic area of Iraq. Methods This retrospective cross-sectional study was conducted at Smart Health Tower in Sulaymaniyah, Iraq, from May 2020 to May 2024. It involved patients diagnosed and treated for CE. Data was collected using detailed case forms covering patient demographics, cyst location, presentation, medical and surgical history, and recurrence. Results The study involved 605 CE patients with nearly equal gender distribution and a mean age of 40.1 ± 18.6 years. Most patients, 217(35.9%), were aged 31-50 and lived in urban areas 505(83.5%). The majority, 382(63.1%), were asymptomatic, with liver cysts being the most common 361(59.7%). Single cysts were more prevalent in 513(84.8%) cases, with surgery performed in 222(36.7%) of cases, and recurrence was rare 8(1.3%). Conclusion This study highlights a significant burden of CE in urban areas, where asymptomatic cases often lead to delayed diagnosis. The high prevalence of liver and lung cysts underscores the necessity for targeted public health strategies and enhanced control measures for free-roaming dogs.

Macrophage colony-stimulating factor receptor/CD115+ non-classical monocytes are expanded in systemic lupus erythematosus and associated with lupus nephritis

Objective In systemic lupus erythematosus (SLE), the non-classical monocyte compartment is expanded, but its phenotype and association with clinical disease manifestations have not been explored. Method Monocyte subsets from 39 SLE patients, 32 healthy age-matched controls, and 16 patients from a disease control (autoimmune connective tissue disease other than SLE) were determined based on CD14 and CD16 surface expression. Cell surface expression of the receptors for macrophage colony-stimulating factor (M-CSF) (CD115) and granulocyte–macrophage colony-stimulating factor (GM-CSF) (CD116), as well as 6-Sulpho LacNAc (slan), were analysed by flow cytometry. The association of monocyte populations with disease manifestations, disease activity markers, and current medication of each patient was analysed by chart review. Results Non-classical monocytes displayed a cell-type specific signature of high M-CSF receptor CD115 and low GM-CSF receptor CD116 expression that separated them from the other two monocyte subsets. In healthy individuals, the M-CSF receptor on non-classical monocytes was an age-dependent surface marker, with lower expression in young adults. However, SLE monocytes were characterized by a marked expansion of M-CSF receptor/CD115+ non-classical monocytes in patients of all ages. The expanded population of M-CSF receptor/CD115+ non-classical monocytes was associated with lupus nephritis but not with disease activity, and coexpressed slan. Conclusion The non-classical monocyte subset in SLE is characterized by an expansion of M-CSF receptor/CD115+ cells that are associated with lupus nephritis and coexpress slan.

Circulating Interleukin-22 in Patients with Acute Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

Acute coronary syndrome (ACS) represents an important clinical manifestation of coronary artery disease (CAD) and is characterized by a particularly poor prognosis. Myocardial reperfusion through primary percutaneous coronary intervention (PPCI) is imperative in the event of acute ST elevation myocardial infarction (STEMI). Interleukin-22 (IL-22) regulates immune and inflammatory responses. This interleukin has been described in the scenario of the CAD, but there are no data in patients with STEMI undergoing PPCI. Objectives: The goals of this study were to investigate the differences in circulating IL-22 levels between patients with STEMI undergoing PPCI and healthy controls and to determine whether these differences were associated with the culprit coronary artery, door-to-balloon time (DBT), final angiographic result, CAD classification, and presence of diabetes mellitus (DM). Methods: A total of 280 participants were recruited, comprising 210 STEMI cases and 70 healthy controls. Participants underwent clinical and angiographic evaluations, and serum IL-22 levels were measured using an enzyme-linked immunosorbent assay (ELISA). Data analysis was performed using the Mann-Whitney and Fisher tests, with p < 0.05 indicating significance. Results: Serum IL-22 levels were lower in cases (149.63, 84.99-294.56) than in the controls (482.67, 344.33-641.00); p < 0.001. Lower IL-22 levels were associated with the right coronary artery (RCA) (144.57, 70.84-242.43; 146.00, 63.60-279.67; 191.71, 121.80-388.97); p = 0.033. IL-22 was lower with shorter DBT (≤60 min, 106.00, 49.60-171.71; >60 min, 153.00, 88.86-313.60); p = 0.043. Conclusions: IL-22 levels were significantly lower in patients with STEMI than in healthy controls.
