Gout is a picturesque presentation of uric acid disturbance. It is the most well understood and described type of arthritis. Its epidemiology is studied. New insights into the ...pathophysiology of hyperuricemia and gouty arthritis; acute and chronic allow for an even better understanding of the disease. The role of genetic predisposition is becoming more evident. The clinical picture of gout is divided into asymptomatic hyperuricemia, acute gouty arthritis, intercritical period, and chronic tophaceous gout. Diagnosis is based on laboratory and radiological features. The gold standard of diagnosis is identification of characteristic MSU crystals in the synovial fluid using polarized light microscopy. Imaging modalities include conventional radiography, ultrasonography, conventional CT, Dual-Energy CT, Magnetic Resonance Imaging, nuclear scintigraphy, and positron emission tomography. There is remarkable progress in the application of ultrasonography and Dual-Energy CT which is bound to influence the diagnosis, staging, follow-up, and clinical research in the field. Management of gout includes management of flares, chronic gout and prevention of flares, as well as management of comorbidities. Newer drugs in the pharmacological armamentarium are proving successful and supplement older ones. Other important points in its management include patient education, diet and life style changes, as well as cessation of hyperuricemic drugs.
Background. Anaemic syndrome of complex origin is not uncommon in urinary tract infection, particularly in dietary non-adherence, menstrual cycle disorders, or concomitant digestive diseases, ...recurrent respiratory infections, etc. However, there is currently insufficient epidemiological data on this comorbidity in the literature. This study aims to establish the features of pyelonephritis course in its combination with anaemic syndrome in children. Materials and methods. We analysed the medical records of 200 children aged 0 to 17 years with acute non-complicated pyelonephritis, complicated and recurrent urinary tract infections for 2012–2017. In the second stage of our work, we comprehensively examined 85 girls aged 11 to 17 who underwent inpatient treatment between 2018 and March 2023. Thirty children of the same age and gender made up the comparison group. A paediatric gastroenterologist, a paediatric gynaecologist and/or urologist examined all patients. Immunochemical method with electrochemiluminescence immunoassay was used to assess ferritin content; also, serum iron and total iron-binding capacity were measured. Results. Anaemic syndrome is common in most girls with urinary tract infections (58.8 % of сases). Among the causes, the following are distinguished: menstrual cycle disorders with abnormal uterine bleeding (50.0 %), chronic digestive disorders, in particular malabsorption syndrome of unknown origin (25.0 %), recurrent bronchopulmonary disorders (15.0 %), and unbalanced diet (10.0 %). The features of urinary tract infections and concomitant iron deficiency in children include fatigue (55.0 % in acute non-complicated pyelonephritis vs. 40.0 % in complicated urinary tract infections, р < 0.05), dizziness (35.0 % in acute non-complicated pyelonephritis vs. 15.0 % in recurrent urinary tract infections, χ2 = 48.6532, р < 0.05), and pallor (25.0 % in complicated urinary tract infections vs. 10 % in recurrent urinary tract infections, χ2 = 0.7168, р > 0.05). The ferritin level was the highest in patients with complicated urinary tract infections (18.2 µg/mL). In patients with recurrent urinary tract infections, this indicator was the lowest — 5.0 µg/mL. Conclusions. Retrospective analysis of medical records confirmed the presence of anaemia in 30.0 % of girls with inflammatory kidney diseases. During the physical examination, 58.8 % of female adolescents with urinary tract infections had signs of anaemic syndrome.
Microscopic polyangiitis (MPA) is one of the three clinical phenotypes of vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA). Although MPA is considered a rare form of ...ANCA-associated vasculitis (AAV), clinical evidence shows that it is fairly common among nephrologists, as it manifests as a systemic, weak-immune vasculitis affecting glomerular capillaries, resulting in necrotizing glomerulonephritis (GN) diagnosed in nearly 100% of MPA patients. The issue of AAV in general, and MPA specifically, has gained significant importance in the context of the ongoing SARS-CoV-2 coronavirus pandemic, as both conditions share common anatomical sites of infection and inflammation. This study presents three new cases of MPA in post-COVID-19 patients. The analysis and presentation encompassed demographic data, patient history regarding comorbidities, details of follow-up care, chronology with COVID-19, and laboratory findings at the time of MPA diagnosis. A comparative analysis of the chronological progression of MPA in the documented clinical cases reveals the polymorphic nature of early-stage clinical manifestations, as well as diverse patterns of disease progression in the advanced stage. Additionally, we provide a brief literature review on diagnostic challenges, pathogenetic mechanisms underlying the relationship between SARS-CoV-2 and AAV, and peculiarities of clinical presentations in early and advanced stages of MPA.
