Assessment of IL-8 Levels in Saliva of Healthy and Chronic Periodontitis Individuals

ABSTRACT Inflammation of the gums and other tissues supporting the teeth, as well as gradual loss of attachment and bone, are the results of chronic periodontitis, an infectious illness. During inflammation, a group of low molecular weight proteins called cytokines facilitate a complex interaction between inflammatory cells (such neutrophils) and other cellular components in connective tissue. The cytokine interleukin-8 (IL-8) is a potent neutrophil chemoattractant. Therefore, it is possible that IL-8 is crucial to the development of periodontitis’s pathology. Objectives: 1) To estimate concentration of IL-8 levels in healthy individuals and chronic periodontitis individuals. 2) To compare IL-8 levels in healthy and chronic periodontitis individuals Materials and Methods: Participants in this research will be recruited from among those who visit the outpatient department (OPD) at the NGH Institute of Dental Sciences and Research Centre, Belagavi, run by the Maratha Mandal. Control Group: Subjects with no clinical attachment loss (CAL) and a probing depth of 3.0 mm are considered to be periodontally healthy. Those in Group 2 (chronic periodontitis) have a chronic form of the disease, as shown by a probing pocket depth (PPD) of less than 5 mm and CAL of less than 2 mm. Unstimulated saliva sample will be collected in a 5 mL wide-mouthed sterile container by spitting method. Samples collected will be centrifuged. The supernatant is collected and stored at –80°C and then assayed for IL-8 concentration by using the standardized IL-8 ELISA kit.

The Unveiled Triad: Clinical, Radiological and Pathological Insights into Hypersensitivity Pneumonitis

Hypersensitivity pneumonitis (HP) is a diffuse parenchymal lung disease (DLPD) characterized by complex interstitial lung damage with polymorphic and protean inflammatory aspects affecting lung tissue targets including small airways, the interstitium, alveolar compartments and vascular structures. HP shares clinical and often radiological features with other lung diseases in acute or chronic forms. In its natural temporal evolution, if specific therapy is not initiated promptly, HP leads to progressive fibrotic damage with reduced lung volumes and impaired gas exchange. The prevalence of HP varies considerably worldwide, influenced by factors like imprecise disease classification, diagnostic method limitations for obtaining a confident diagnosis, diagnostic limitations in the correct processing of high-resolution computed tomography (HRCT) radiological parameters, unreliable medical history, diverse geographical conditions, heterogeneous agricultural and industrial practices and occasionally ineffective individual protections regarding occupational exposures and host risk factors. The aim of this review is to present an accurate and detailed 360-degree analysis of HP considering HRCT patterns and the role of the broncho-alveolar lavage (BAL), without neglecting biopsy and anatomopathological aspects and future technological developments that could make the diagnosis of this disease less challenging.

Late-onset and long-lasting neutropenias in the young: A new entity anticipating immune-dysregulation disorders.

This study identifies a new chronic form of immune neutropenia in the young with or without detectable indirect anti-neutrophil antibodies, characterized by mild/moderate neutropenia low risk of severe infection (14%), tendency to develop autoimmune phenomena over the course of the disease (cumulative incidence of 58.6% after 20 years of disease duration), leukopenia, progressive reduction of absolute lymphocyte count and a T- and B-cell profile similar to autoimmune disorders like Sjogren syndrome, rheumatoid arthritis, and systemic lupus erythematosus (increased HLADR+ and CD3 + TCRγδ cells, reduced T regulatory cells, increased double-negative B and a tendency to reduced B memory cells). In a minority of patients, P/LP variants related to primary immuno-regulatory disorders were found. This new form may fit the group of "Likely acquired neutropenia," a provisional category included in the recent International Guidelines on Diagnosis and Management of Neutropenia of EHA and EUNET INNOCHRON ACTION 18233. The early recognition of this form of neutropenia would help clinicians to delineate better specific monitoring plans, genetic counseling, and potentially targeted therapies.

Review of publications on drug-related problems investigations in osteoporosis patients

A chronic form of osteoporosis (OP) substantiates a long-term pharmacotherapy of patients, which increases the risk of adverse drug reactions (ADRs) during the therapy. The enhancement of requirements to the quality of safety monitoring carried out in the context of pharmacovigilance and the newly identified safety problems require an improvement of the system of quality control of medicinal products (MPs).The aim of the work was to review the application of a new promising method for monitoring the drug safety – the system of Drug-Related Problems (DRP) in the osteoporosis pharmacotherapy.Materials and methods. The following databases and search engines were used to retrieve scientific papers by Russian and foreign authors: PubMed, elibrary.ru, Google Scholar, CyberLeninka, Russian National Library. The information sources were searched using the following keywords and word combinations: “drug-related problems”, “drug safety”, “osteoporosis” (in Russian and English, respectively), as well as the corresponding MeSH terms.Results. The application of DRP system in the health care of different countries was reviewed, and the risk factors of the problems associated with the use of MPs, the appropriate interventions in case of the detection of high DRP values were investigated. The study of the problems associated with the use of MPs for the treatment of OP during the complex pharmacotherapy made it possible to determine the feasibility of using this method to improve the safety and effectiveness of this kind of treatment in patients.Conclusion. The analysis of emerging DRPs makes it possible to increase patients’ adherence to the treatment and stop the ADRs. This improves the quality of life of patients and increases the effectiveness of pharmacotherapy. The introduction of such a method of the drug safety research into the system of pharmacovigilance of the Russian Federation is an important step in the development of personalized medicine. A further study of problems associated with the use of drugs in OP patients will also help to reduce the risks arising during the combination pharmacotherapy.

A chronic form of tick-borne encephalitis. Case report

Background: Chronic tick-borne encephalitis is a rare and not fully understood pathology in which the body is not able to completely get rid of the virus. The virus remains in the nervous system mainly in the motor structures, supporting the degenerative-inflammatory process in them. Clinical case description: A clinical case of a chronic form of tick-borne encephalitis, steadily progressing, in a young man with a completely intact cognitive sphere is described. Damage to the motor nuclei of the trunk, motoneurons of the anterior horns of the spinal cord led to gross bulbar disorders, severe diffuse muscle atrophy with difficulty in independent movement. Conclusion: The above observation of the amyotrophic form of tick-borne encephalitis reflects the remitting-progressive nature of the course for 1.5 years.

The Trimeric Autotransporter Adhesin EmaA and Infective Endocarditis.

Infective endocarditis (IE), a disease of the endocardial surface of the heart, is usually of bacterial origin and disproportionally affects individuals with underlying structural heart disease. Although IE is typically associated with Gram-positive bacteria, a minority of cases are caused by a group of Gram-negative species referred to as the HACEK group. These species, classically associated with the oral cavity, consist of bacteria from the genera Haemophilus (excluding Haemophilus influenzae), Aggregatibacter, Cardiobacterium, Eikenella, and Kingella. Aggregatibacter actinomycetemcomitans, a bacterium of the Pasteurellaceae family, is classically associated with Aggressive Periodontitis and is also concomitant with the chronic form of the disease. Bacterial colonization of the oral cavity serves as a reservoir for infection at distal body sites via hematological spreading. A. actinomycetemcomitans adheres to and causes disease at multiple physiologic niches using a diverse array of bacterial cell surface structures, which include both fimbrial and nonfimbrial adhesins. The nonfimbrial adhesin EmaA (extracellular matrix binding protein adhesin A), which displays sequence heterogeneity dependent on the serotype of the bacterium, has been identified as a virulence determinant in the initiation of IE. In this chapter, we will discuss the known biochemical, molecular, and structural aspects of this protein, including its interactions with extracellular matrix components and how this multifunctional adhesin may contribute to the pathogenicity of A. actinomycetemcomitans.

Cardioprotection with levocarnitine intracoronary administration during percutaneous coronary interventions

Currently, the number of percutaneous coronary interventions (PCI) performed in acute and chronic forms of coronary heart disease continues to grow: every year their number reaches at least 5,000,000 worldwide, and more than 200,000 of them in Russia. The main causes of postoperative mortality are perioperative myocardial infarction and acute heart failure due to inadequate protection of the myocardium from ischemia/reperfusion under conditions of balloon expansion and stenting of the affected coronary arteries. The review presents experimental and clinical literature data on the successful use of levocarnitine for cardioprotection in patients with various forms of coronary heart disease and patients with chronic heart failure, both with intravenous administration and as part of a cardioplegic solution during heart surgery. The intracoronary route of administration of levocarnitine solution during PCI in high-risk patients (elderly and senile patients, with multivessel lesions of the coronary bed, difficulties in conducting the intervention) is substantiated. The description of two clinical cases of the use of the technique in elderly patients with acute forms of coronary heart disease with multivessel lesion is given. The postoperative period proceeded without complications with smooth dynamics of biomarkers (troponin I, total creatinephosphokinase, MB-fraction of creatinephosphokinase, lactate dehydrogenase), ischemic ECG shifts were little pronounced. The expected results of the application of the technique are a reduction in intraoperative and postoperative complications of ischemia/ reperfusion and an increase in the effectiveness of the clinical results of PCI in high-risk patients.

About chronic cerebrovascular insufficiency caused by cardiac pathology (literature review)

The widespread introduction of cardiological diagnostic methods in clinical angioneurology has significantly enriched the data on the role of cardiovascular diseases in the development of cerebrovascular pathology. Various cardiac disorders play a significant role in the development of cardioembolic and haemodynamic ischaemic strokes. It has been scientifically proven that chronic heart failure, along with hypertension, is a risk factor for the occurrence of a chronic form of cerebrovascular disease — chronic cerebrovascular insufficiency. The characteristic feature of all types of cardiovascular insufficiency is the inability of the circulatory system to deliver to the organs, systems, tissues, including the brain, the amount of blood necessary for their normal functioning, both at rest and especially during exertion. In their daily practice, neurologists encounter patients with chronic heart failure and symptoms of cerebrovascular disease (memory loss, reduced performance, depression). Underestimation of these conditions can result in a shortened life due to irreversible damage to target organs (heart, brain, kidneys). In the absence of adequate treatment, death is possible within the first 5 years after the onset of heart failure. The degree of disease progression depends on many factors: clinical and pathogenetic variant of chronic heart failure, the rate of the pathological process, the presence of myocardial damage and remodeling, complications from target organs. In this article, we tried to analyse the literature data of domestic and foreign authors on the pathogenetic mechanisms of chronic heart failure, the impact on its development and the course of its complications, and, above all, brain damage in the form of chronic cerebrovascular insufficiency.

Clinical case of acute hepatitis in a patient with ascariasis

Helminthiases are fairly widespread human parasitic diseases caused by various lower worms - helminths. In the Russian Federation, more than 4.5 million cases of helminthiasis were registered in 2016. According to the WHO Expert Committee, ascariasis affects about 900 million people in the world every year, most of whom are children of preschool and school age. In the Russian Federation, 24,115 cases of ascariasis were registered in 2015. The true prevalence of helminthiasis is much higher. In recent decades, there has been an increase in and manifestation of new helminth infestations as a result of changes in economic and socio-economic conditions, increased migration, and the introduction of helminths, common in countries with tropical and subtropical climates, to Russia. The possibility of a patient having one or another type of helminthiasis is practically not taken into account in clinical practice, which leads to incorrect diagnosis, the development of complications of the disease, and its transition to a chronic form. As a rule, helminthiases are relatively asymptomatic, but in some cases their local manifestations come to the fore clinically and the disease occurs under the guise of infectious and non-infectious diseases.

Clinical and laboratory assessment of the antibacterial effectiveness of anodic dissolution of copper electrodes during endodontic treatment of teeth with partially obliterated root canals

The aim of the work was to study the antibacterial effectiveness of anodic dissolution of copper electrodes in endodontic treatment of teeth with root canals obliterated by more than half the length of the root.The study included two stages: experimental and clinical. In an experimental study using automatic cultivation of microorganisms in liquid nutrient media, it was found that anodic dissolution of a silver-copper electrode was more effective with respect to the clinical isolate of P. Intermedi and of C. Albicans, as well as a mixed culture of pathogenic microorganisms Streptococcus sanguis + Enterococcus faecium – a copper electrode. In the clinical part of the study, 30 patients with chronic forms of pulpitis were treated using intra-channel anodic dissolution of a copper electrode in the teeth, where the root canals were obliterated by more than half the length of the tooth root.After the procedure, not a single type of pathogenic microorganisms found in the root canals before treatment was detected. All patients had no complaints, and a control X-ray examination showed no pathological changes after year treatment.

Navigating Q fever: Current perspectives and challenges in outbreak preparedness.

Q fever, also known as query fever, is a zoonotic illness brought on by the Coxiella burnetii bacteria. This disease was first discovered in 1935 in Queensland, Australia. Worldwide, Q fever is a disease that requires notification, and certain nations classify it as a national health concern. A feature of C. burnetii is known as cell wall phase fluctuation. Serological testing is the main method used to diagnose Q fever illnesses. Inhalation is the primary method of C. burnetii transmission in both people and animals, with smaller amounts occurring through milk and milk product ingestion. The bacterial strain that is causing the infection determines how severe it is. Q fever is a significant zoonosis that can be dangerous for personnel working in veterinary laboratories, livestock breeding operations, and slaughterhouses due to its high human contagiousness. Coxiella burnetii is a biological weapon that can be sprayed on food, water, or even mail. It can also be employed as an aerosol. Antibiotics work well against this disease's acute form, but as the infection develops into a chronic form, treatment becomes more difficult and the illness frequently returns, which can result in a high death rate. Vaccination has been demonstrated to lower the incidence of animal infections, C. burnetii shedding, and abortion. Several hygienic precautions should be put in place during an outbreak to lessen the spread of disease to animals.

Гіперсенситивний пневмоніт. Клінічний випадок

Abstract. Hypersensitivity pneumonitis (HP), or exogenous allergic alveolitis, is a complex and heterogeneous immune-mediated inflammatory and/or fibrotic disease of the lung parenchyma, small airways and interstitium that occurs in people with congenital or acquired hypersensitivity/ susceptibility to certain inhaled antigens. The disease can occur in acute/inflammatory form (duration of the disease is less than 6 months) or chronic form (duration of the disease is more than 6 months). According to the latter classification, HP is divided into fibrotic and non-fibrotic forms: non-fibrotic HP is a mild form of HP compared to fibrotic HP. However, non-fibrotic HP often progresses to fibrosis, i.e. it can be recurrent. The article describes a clinical case of acute HP induced by poultry antigens in the occupational environment. The clinical case study shows that the anamnesis data, namely the identification of a direct link between the occupational environment and the onset of symptoms of dyspnoea, cough, weakness, and headache, made it possible to suspect poultry antigen-induced HP. The characteristic picture of HP observed on computed tomography images, as well as auscultation and radiological findings, made it possible to confirm the diagnosis. The results of the respiratory function assessment showed the presence of pulmonary insufficiency, and the laboratory examination data showed the presence of inflammation, immunological imbalance, acid-base (alkaline) disorders and hypoxia.

Clinical Spectrum of Hereditary Tyrosinemia Type 1 in a Cohort of Pakistani Children.

Hereditary Tyrosinemia Type 1 (HT1), a rare autosomal recessive metabolic disorder, arises from fumarylacetoacetate (FAH) enzyme deficiency, resulting in toxic metabolite buildup. It manifests in acute, subacute, and chronic forms, with early diagnosis and Nitisinone treatment being vital. The study aims to highlight the different clinical presentations of Hereditary Tyrosinemia type 1 in a cohort of Pakistani children. Retrospective observational study. All patients diagnosed with HT1 at Shifa International Hospital, Islamabad and Pak Emirates Military Hospital, Rawalpindi between 2010 and 2023 were included. Information was collected regarding age, gender, symptoms, physical signs, and laboratory results. The study identified 6 cases of HT1. The average age at presentation was 8 months, with a mean delay in diagnosis of 26.8 months. Males were 4 (66.7%) and 2 (33.3%) were females. All patients had underlying liver disease presenting as abdominal distension with hepatosplenomegaly and accompanying growth failure. Four cases presented with rickets, 2 of which had hypophosphatemic rickets. Urine for succinylacetone was raised in all patients. Alpha fetoprotein was raised but hepatocellular carcinoma was diagnosed in 1 patient only. Low protein diet, and vitamin supplements were used for management. Five of the 6 patients died within 2 years of diagnosis. Delayed referrals and unavailability of Nitisinone are the major challenges in diagnosing and treating HT1 in Pakistan.

Non infectious ocular surface inflammation: Paediatric GVHD

Although ocular findings and treatment for GVHD are described in adult patients, the literature describing this condition in paediatric patients is relatively few. In children, detection of symptoms and diagnosis of ophthalmic findings are more difficult than in adults, as history taking, clinical examination and diagnostic tests such as fluorescein staining or Schirmer tests are difficult to perform due to limited cooperation. Also patients cannot specify their complaints and symptoms especially in younger age group. Follow‐up and frequent ophthalmic evaluation are important in diagnosis and management of children who had bone marrow transplantation. Even though ophthalmic findings are common in children, usually milder than adults but timely diagnosis and management are very important to decrease secondary eye complications such as corneal ulcers and vision loss and also to improve quality of life.Graft‐versus‐host disease (GVHD) is a major complication of bone marrow transplantation that is performed for haematological malignancies and diseases and seen in 50–70% of cases. It is a complex clinical disease with many organ and system involvement. Acute form is seen in the first 3 months after transplantation, systemic manifestation mainly include hepatitis and skin involvement and chronic form is mostly seen after acute GVHD. Ocular manifestations can be classified as acute and chronic and also as anterior and posterior. Most common ocular finding is dry eye with corneal involvement and seen in 40–90% of patients with chronic GVHD. Corneal vascularization, keratitis and even perforation can be seen. Conservative treatment with topical steroids, autologous serum, lubricant eye drops and ointments should be integrated with topical cyclosporine‐A that might be an effective and safe treatment option in dry eye related to chronic GVHD.

Risk Factors and Management of Acute Pancreatitis; A Systematic Review

Pancreatitis, characterized by pancreatic inflammation, commonly stems from triggers such as gallstones and excessive alcohol consumption. Gene-environment interactions intricately contribute to disease onset and progression, challenging the traditional classification of acute, recurring, and chronic pancreatitis as distinct entities. Instead, a disease continuum has emerged, where 30% of acute pancreatitis cases progress into a chronic form, often involving episodes of recurrence. This systematic study aims to explore the Risk Factors and Management of Acute Pancreatitis. Data from PubMed/Medline, Scopus databases, and Embase were analyzed following PRISMA guidelines (2010–2023). Among 329 identified studies, 15 met inclusion criteria, primarily employing surveys and national database analyses. Enhanced comprehension of risk factors, diagnosis, and treatment is crucial for refining future evaluation and management strategies. Pancreatitis exhibits multifaceted characteristics, presenting diverse causes, symptoms, and outcomes. Current understanding of its natural history and treatment remains limited. Long-term follow-up and randomized studies are imperative to unravel gene-environment interactions and formulate innovative therapeutic approaches. The increased incidence has facilitated progress in defining pancreatitis, with identified risk factors including biliary issues, anatomical abnormalities, systemic diseases, medications, trauma, genetics, infections, and metabolic factors. Notably, the proportion of idiopathic cases has decreased due to improved recognition of genetic and anatomical variants. Effective acute pancreatitis management necessitates early and aggressive fluid and nutritional therapy, pain control, and addressing precipitating factors.

Anaesthetic Management of a Patient with Guillain-Barré Syndrome undergoing Proximal Humerus Fracture Surgery: A Case Report

Guillain-Barré Syndrome (GBS) is an autoimmune disorder which can present in acute and chronic forms. It is an inflammatory demyelinating polyneuropathy. These patients pose potential perioperative risks of autonomic dysfunction and respiratory muscle weakness. The current case report shows a 66-year-old female with a history of a fall at home eight days prior to surgery, diagnosed with a right-sided proximal humerus fracture. The patient was a diagnosed case of GBS and hypertension since five years. For GBS, she had a history of Intensive Care Unit (ICU) admission for both upper and lower limb muscle weakness and breathlessness. She recovered with treatment of Intravenous Immunoglobulin (IVIg) and oxygen therapy. The weakness improved gradually over time but did not fully recover. The patient continued to have weakness in both lower and upper limbs prior to surgery. The patient underwent Joshi’s External Stabilising System (JESS) fixation surgery for the right proximal humerus fracture. Ultrasound-guided (USG) interscalene and superficial cervical plexus block were performed in view of pre-existing muscle weakness and to reduce the requirement of postoperative ventilator support. The intraoperative course was uneventful. The patient’s sensory and motor power returned to the same prior to surgery after the block’s effects subsided.

Functional responses in American marten habitat selection indicate cumulative effects of progressive habitat change

AbstractShifts in habitat selection may serve as behavioral indicators of changing habitat quality and can provide an insight into the effects of chronic disturbance on wildlife populations before rates of occurrence and other metrics related to population viability are affected. Long‐term studies can provide unique opportunities to understand animals' behavioral responses to the cumulative effects of habitat disturbance that may be missed by short‐term studies or space‐for‐time substitution. Using the American marten (Martes americana) as a focal species, we evaluated the effects of progressive habitat disturbance on an animal population by identifying changes in habitat availability and selection over time. Marten are strongly associated with mature forest conditions and are thus sensitive to forest harvesting, which is a chronic and prevalent form of disturbance across the species' range. We developed resource selection functions that characterized both temporally consistent patterns and functional responses in the relative selection of habitats by marten at the patch scale. We used a combination of marten location data collected during three periods over 30 years of extensive forest change in northern Maine and a habitat classification scheme informed by species' behavior and designed to capture habitat changes over time. Marten increased their selection of tall (>12 m mean tree height) mature forest, including uncut forest and regenerated clearcuts, in response to decreased availability. Marten also increased avoidance of early‐successional forest (<9 m mean tree height) in response to increased availability. These functional responses in habitat selection appear to enable marten to maintain access to required resources in mature forest and limit exposure to risky or resource‐poor habitat within home ranges. However, a declining trend in the occurrence of resident adult females may indicate a limit to the functional response strategies for individuals unable to incur the energetic or prey‐related costs that may be associated with strong functional responses. Our results suggest that, despite adaptive habitat selection strategies, there are minimum thresholds of mature forest availability below which resident adults, particularly females, will struggle to persist. We recommend forest management strategies targeted at minimizing the strength of functional responses displayed by marten within occupied landscapes.

Machine Perfusion and Bioengineering Strategies in Transplantation-Beyond the Emerging Concepts.

Solid organ transplantation has progressed rapidly over the decades from the first experimental procedures to its role in the modern era as an established treatment for end-stage organ disease. Solid organ transplantation including liver, kidney, pancreas, heart, and lung transplantation, is the definitive option for many patients, but despite the advances that have been made, there are still significant challenges in meeting the demand for viable donor grafts. Furthermore, post-operatively, the recipient faces several hurdles, including poor early outcomes like primary graft dysfunction and acute and chronic forms of graft rejection. In an effort to address these issues, innovations in organ engineering and treatment have been developed. This review covers efforts made to expand the donor pool including bioengineering techniques and the use of ex vivo graft perfusion. It also covers modifications and treatments that have been trialed, in addition to research efforts in both abdominal organs and thoracic organs. Overall, this article discusses recent innovations in machine perfusion and organ bioengineering with the aim of improving and increasing the quality of donor organs.

Masticatory efficiency in patients with acute and chronic forms of masticatory muscle disorders

Introduction. Masticatory muscle disorders are frequently encountered in clinical dental practice, with a varied impact on the functionality of the stomatognathic system. The rehabilitation of mastication is a central objective in the treatment of these pathologies, thus there are required to employ objective and qualitative indices for the assessment and treatment efficiency quantification for the masticatory function. Aim of the study: Evaluation of masticatory efficiency parameters through the mixing ability test in patients with acute and chronic phases of masticatory muscle disorders. Material and methods. There were investigated 55 patients with masticatory muscle disorders (females, average age — 28.1 ±5.02 years), divided into 2 groups according to the phase of the disease (acute/chronic). There were determined the values of the descriptive indices of the dysfunctional process (pain intensity, severity of dysfunction, mandibular mobility, functional limitation). Masticatory efficiency was assessed subjectively and objectively based on mixing ability test indices. Results. In the chronic phase of masticatory muscle dysfunction, there is a more pronounced expression of the parameters of the dysfunctional process, but masticatory efficiency is rarely severely affected, possibly due to the initiation and involvement of functional compensation and adaptation mechanisms.

Use of C-reactive protein as a marker for Lyme disease in Bernese Mountain Dogs – a preliminary study

The aim of the study was to determine the correlation between serum C-reactive protein (CRP) levels, the presence of antibodies to B. burgdorferi, and the occurrence of clinical signs of Lyme borreliosis in Bernese Mountain Dogs (BMDs). The study included 54 BMDs divided into three groups. The first group (n = 29) consisted of animals with signs suggestive of Lyme disease and rapid tests showing the presence of antibodies to B. burgdorferi in their serum. The second group (n = 15) included dogs that did not show signs of Lyme disease and had antibodies to spirochetes in their serum. The third group consisted of BMDs (n = 10) that showed no signs of disease and in whose serum no antibodies to B. burgdorferi were detected by rapid tests. Of the 29 dogs in the first group, 18 had elevated CRP levels. These animals showed signs of arthritis and renal failure. After treatment with doxycycline, the clinical signs of the disease disappeared, and the CRP concentration decreased to normal levels in 16 dogs. In the second group, 2 animals had elevated CRP levels, while in the third group, no antibodies to spirochetes were detected in the serum of any of the dogs, and CRP levels remained within the physiologically normal range. Our own observations indicate that C-reactive protein is a promising marker for monitoring the effectiveness of Lyme disease therapy in BMDs, as well as for distinguishing asymptomatic positive seroreagents from dogs of this breed that are actually suffering from the disease. However, to confirm its usefulness, further research is needed on representatives of this breed, especially those suffering from a chronic form of the disease.
