IgA vasculitis after COVID-19: a case-based review.

IgA-associated vasculitis (IgAV) known as Henoch - Schönlein purpura (HSP) disease is an inflammatory disorder of small blood vessels. It's the most common type of systemic vasculitis in children which can be associated with the inflammatory process following infections. IgA vasculitis is a rare and poorly understood systemic vasculitis in adults. Coronavirus disease 2019 (COVID-19) has been associated with HSP in both adults and children. A 58-year-old woman was diagnosed with HSP, fulfilling the clinical criteria: palpable purpura, arthritis, hematuria. The disclosure of the HSP disease was preceded by a infection of the respiratory tract. COVID-19 infection was confirmed via the presence of IgM and IgG antibodies. This case indicates the possible role of SARS-CoV-2 in the development of HSP. The clinical course of IgAV in adults appears to be different from pediatric IgAV, especially due to higher risk of renal complications. Symptoms of the disease quickly resolved with low-dose of steroids.

Giant haematoma of the posterior compartment of thigh in a patient with coronavirus disease 19 pneumonia and pulmonary embolism - Case Report.

Introduction. During the Coronavirus-19 (Covid-19) pandemic, a significant increase in the frequency of complications in the form of venous thrombosis was observed. However, there is also the other side of the coin - an increase in the tendency to bleeding in the course of COVID19. Case Report. We present the case of a patient hospitalised in the COVID-19 Isolation Ward due to severe pneumonia in the course of SARS-CoV2 infection. She developed respiratory failure requiring a non-invasive mechanical ventilation. In addition, pulmonary embolism was diagnosed, the treatment with low molecule heparin was initiated. Soon, the patient developed a huge haematoma of the posterior compartment of the thigh causing deformation and dysfunction of the limb and resulting with acute haemorrhagic anaemia. Conclusion. Our article is a contribution to the discussion on the need to pay attention to the possibility of haemorrhagic complications in the course of anticoagulant treatment due to venous thrombosis in COVID-19 patients.

Acute liver injury in the course of COVID-19.

Although coronavirus disease 19 (COVID-19) most often affects the respiratory system, in the course of this disease, dysfunction of many other organs may also develop. The case is presented of a female patient, treated for a long time due to chronic obstructive pulmonary disease, complicated by chronic complete respiratory failure, and who was undergoing non-invasive mechanical ventilation at home. She was admitted to the Pneumonology Department due to exacerbation of the symptoms of her underlying disease. Several tests for SARS-CoV2 infection gave a negative result. During the patient's stay in the clinic, a rapid increase was observed in symptoms of respiratory failure, heart failure, and laboratory signs of acute liver damage. The next PCR test result proved to be positive. In addition to the case report, the possible impact of SARS-CoV2 infection on liver damage is also also discussed, along with a literature review on this topic.

Various Forms of Tuberculosis in Patients with Inflammatory Bowel Diseases Treated with Biological Agents.

Although there are undeniable advantages of treatment of the inflammatory bowel diseases, Crohn's disease, and ulcerative colitis, with biological agents, the increased susceptibility to tuberculosis should not be ignored. Tuberculosis is an infectious disease caused by the Mycobacterium tuberculosis complex which includes M. tuberculosis, M. bovis, and M. africanum. Primary tuberculosis is uncommon in the setting of inflammatory bowel disease: reactivation of latent tuberculosis is of greater concern. Consequently, latent infection should be excluded in patients who qualify for immunosuppressive treatments. Apart from the review of the literature, this article also presents three cases of different patterns of tuberculosis that occurred during treatment with infliximab, adalimumab, or vedolizumab. The first case reports a case of tuberculosis presenting as right middle lobe pneumonia. The second case featured miliary tuberculosis of the lungs with involvement of the mediastinal lymph nodes, liver, and spleen. The third patient developed a tuberculoma of the right parietal lobe and tuberculous meningitis. It is important to reiterate that every patient qualifying for a biologic agent should undergo testing to accurately identify latent tuberculosis, as well as precise monitoring for the possible development of one of the various forms or patterns of tuberculosis during treatment.

Short-acting inhaled ß2-agonists: why, whom, what, how?

We showed the present data about the efficacy and safety of inhaled short-acting ß2-agonists (SABA), such as salbutamol and fenoterol, in the management of obstructive diseases in children and adults. Our work discusses major mechanisms of action, clinical effects, possible side effects and indications of inhaled SABA. We presented current recommendations for the position of SABA in the therapy of obstructive diseases in children and adults, particularly in asthma and chronic obstructive pulmonary disease.

Not only cigarettes - other culprits of lung cancer.

Introduction. Before cigarettes became popular, lung cancer was an extremely rare disease, but currently it is the most common cause worldwide of cancer death in both genders. Therefore, it constitutes a huge epidemiological, diagnostic and socio-economic challenge around the world. In Poland, lung cancer is the second most common carcinoma in both men and women, and it is also the most prevailing cause of carcinous death. Undoubtedly, although smoking classical cigarettes is the strongest risk factor of developing the cancer, unfortunately it is not the only one. Objective. The aim of this study was to present smoking-related factors, e.g. cigars, pipes, e-cigarettes or marijuana smoking, etiologically related to lung cancer incidence.

New guidelines for the treatment of seasonal allergic rhinitis.

The paper discusses the classification and forms of allergic rhinitis with a special focus on seasonal allergic rhinitis (SAR). The general principles of SAR management are presented, including the role of nasal glucocorticoids, nasal and oral antihistamines, and antileukotrienes. Based on the latest guidelines, the current rules for the selection of drugs in the therapy of SAR are given, paying special attention to the initial treatment. The aim of the paper is to present updated guidelines for the pharmacological management of patients with seasonal allergic rhinitis.

Eosinophilic airway inflammation is a main feature of unstable asthma in adolescents.

BACKGROUND: Stability of asthma is a clinical phenotype of the disease based on long-term evaluation of control of asthma symptoms and its exacerbations. A relationship between airway inflammation and clinical classification of asthma based on stability criterion has not been well studied. OBJECTIVES: The purpose of our study was to analyze the inflammation profile of stable and unstable asthma in adolescents treated with moderate and high doses of inhaled corticosteroids. METHODS: 139 young asthmatics of 16.8 (3.25) years were classified in the stable group (N = 72) and unstable group (N = 67) after a 3-month prospective observation. Inflammatory markers including cytogram of the induced sputum (IS), fractional exhaled nitric oxide (FeNO) and bronchial hyperresponsiveness (BHR) following provocation with hypertonic saline and exercises, as well as clinical and spirometric parameters in both groups were compared. RESULTS: 75% of patients with unstable asthma revealed elevated percentage of eosinophils in the induced sputum (>2.5%), and mean values were significantly higher in comparison with stable asthma: 2.0 (0,5-4,2) vs 5,5 (2,6-11,3), p < 0,001. Bronchial hyperresponsiveness was markedly higher in unstable asthma, especially in asthma with eosinophilic profile; statistically significant differences also related to functional pulmonary tests. In multivariate analysis, asthma instability was significantly associated with sEos (p = 0.005), BHR (p = 0.001) but not FeNO (p = 0.24). CONCLUSION (AND CLINICAL RELEVANCE): Eosinophilic inflammation, relatively resistant to high doses of inhaled corticosteroids, is a dominant type of inflammation in unstable asthma in adolescents. Asthma instability is also associated with higher bronchial hyperresponsiveness and lower spirometric parameters. In the light of the new studies and progress in biological methods of therapy of eosinophilic inflammation, unstable asthma, especially in case of severe course, requires extended diagnostics with determination of inflammatory phenotype.

Beta-2-adrenoreceptor polymorphism at position 16 determines the clinical severity of chronic obstructive pulmonary disease.

The Arg/Arg homozygosity at codon 16 of the beta-2-adrenoreceptor (ADRB2) gene has been thought to predispose asthma patients to a poorer therapeutic response to beta-2-mimetics, or to worse control of the disease. In contrast, the results of the studies analysing the effect of ADRB2 polymorphisms on the response to beta-2-adrenoreceptor agonists in chronic obstructive pulmonary disease (COPD) patients are sparse and inconclusive. The aim of this research was to verify if p.Arg16Gly (c.46A > G) and p.Gly27Glu (c.79G > C) single nucleotide polymorphisms (SNPs) exert a negative effect on the selected clinical indicators of COPD. The SNPs of the ADRB2 were identified by multiplex allele-specific PCR on DNA isolated from the venous blood leukocytes of 92 patients with stable grade COPD. In addition, all of the patients were asked about the course of COPD during the 12 months preceding the study, including the frequency of exacerbations requiring hospitalisation, the number of antibiotic therapy courses given due to the lower respiratory tract infection, and the number of courses of systemic corticosteroid therapy administered due to the exacerbation of COPD. Arg/Arg homozygotes at codon 16 required at least two courses of antibiotic therapy administered as a result of a lower respiratory tract infection significantly more frequently than carriers of other polymorphic variants of the ADRB2. Moreover, they were the only ones who required three or more courses of corticosteroid therapy due to COPD exacerbation. No significant relationships were observed between the polymorphism at codon 27 and the analysed clinical indicators of COPD severity. These data suggested that Arg/Arg homozygosity at codon 16 of the ADRB2 gene predisposes patients to a clinically more severe course of COPD.

Pulmonary actinomycosis - the great imitator.

Pulmonary localisation represents only 15% of all cases of actinomycosis. The clinical symptoms and radiological changes of this disease are non-specific and sometimes it can be misdiagnosed, usually as tuberculosis, lung cancer or lung abscess. In the reported case, what might look like the lung cancer, finally turned out to be actinomycosis. The interesting case is presented of lung actinomycosis in a 77-year-old farmer, admitted to the Department of Pneumonology, Oncology and Allegology in Lublin due to a massive haemoptysis. CT scan of the chest showed, apart from other changes, the spicular consolidation in the right lung which aroused oncology vigilance. The diagnostic path, which was a real medical challenge, led to the diagnosis of actinomycosis. The process of diagnosis and consequent treatment, which led to the complete regression of clinical and radiological changes, is presented.

[Pneumomediastinum - a case report]. / Odma sródpiersiowa - opis przypadku.

UNLABELLED: Pneumomediastinum is a rare disorder which often occurs without symptoms. It is sometimes a result of an injury but most often it is spontaneous. Pneumothorax may be iatrogenic; one of the reasons might be tracheotomy. Pneumomediastinum in some cases may be the threat to life and health. In this rare cases surgical intervention is needed, however pneumomediastinum is usually spontaneously absorbed. AIM: The aim of this study was to present the differential diagnosis of pneumomediastinum based on the case of a 60-year-old woman with tracheostomy, diagnosed eight years ago with generalized irreversible narrowing of the trachea and bronchi (suspicion of tracheobronchopathia osteochondroplastica). A CASE REPORT: Patient complained of increasing shortness of breath, dry cough and symptoms of upper respiratory tract infections for 2 weeks. In chest CT pneumomediastinum was detected. During bronchoscopy and endoscopic examination of trachea and larynx, no focal lesions of upper respiratory tract and bronchi were detected. By using noninvasive treatment, clinical improvement was achieved. In control chest CT, significant resorption of the air from the mediastinum was detected. Pneumomediastinum occurs often without characteristic symptoms or can be asymptomatic and it is discovered incidentally. If there is no obvious trauma, the cause is usually unknown. In the presented case, after exclusion of the majority of possible causes, we suspected that pneumomediastinum was a complication of tracheotomy but it was not confirmed in endoscopy. It might have been a complication of severe coughing in the course of upper respiratory tract infection or it might have been spontaneous.
