Introduction. Gout in elderly patients is characterized a pronounced comorbid background [2,8-10], which causes difficulties in their management [9]. Objectives of the study. Analysis of the comorbid background for gout in different age groups. Identification of risk factors characteristics, the onset and evolution of gout in elderly people compared to middle-aged patients. Material and methods. To achieve the goal of the cross-sectional study, 237 patients with gout (average age for the men 60±8.0 years and for the women 63±9.0 years) were examined. Results. The patients were separated into two groups, depending on the age of onset of gout: the age of onset up to and including 59 years (group I, 146 people) and the age of onset after 60 years inclusive (group II, 91 people). The average age in group I was 58.1±11.7 years, in group II - 72.8±4.1 years (p<0,1). Conclusions. The average number of concomitant diseases is 2 times higher in the group of gout patients aged 60 years and older (4.0 [3.0; 5.0]) than in the group of patients with gout under the age of 59 years inclusive (2.0 [2.0;3.0], p <0,1), in patients with the onset of gout at the age of 59 years inclusive, the development of coronary artery disease, chronic heart failure and nephrolithiasis occurs significantly earlier than in patients with the onset of gout at the age of 60 years and older (48,4±6,9 years and 59,1±5,0 years; 53,6 ± 3,4 years and 65,6±9,0 years; 37,3±8,9 years and, respectively, 54,9±14,6 years, p<0,05 in all cases).

Objectives. The objective was to evaluate the relationship of comorbid pathology with the clinical and ultrasound characteristics of the evolution of psoriatic arthritis in order to optimize the management. Material and methods. In order to achieve the purpose and objectives of the study, a group of 92 patients with psoriatic arthritis was selected, established in accordance with the CASPAR diagnostic criteria (2006). The patients were treated in the rheumatology and arthrology departments of the Timofei Moşneaga Republican Clinical Hospital and of the Saint Trinity Municipal Clinical Hospital in Chisinau during 2017-2020. A type 1 cohort study is planned (prospective study with retrospective components). Results. Expression at the time of examination of the history data was observed in 54 (58,7%), clinical enthesitis was observed in 47 (51.1%) patients. During the clinical examination of patients, it was found that the frequency of TJC/14 was 11.3% (145/1288), SJC/14 – 4.5% (58/1288), which was 40% (58/145) among all painful joints. During clinical examination, it was found that the TJC of the upper limbs (74/736, 10.1%) and lower (71/552, 12.9%) do not differ significantly (χ2 = 2.489, p = 0.115). At the same time, the SJC of the lower limbs (43/552, 7.8%) was significantly higher than the upper one (15/736, 2.04%) (χ2 = 24.267, p < 0.001). According to ultrasound data, the number of joints examined was 228/1288 (17.7%), number of inflamed entheses – 90/1288 (6.9%), which was 39.5% among the detected synovitis (90/228). The number of enthesitis were 661/4968 (13.3%), of which 19.4% (128/661) of the entheses were vascularized. Conclusions. According to ultrasound data, the frequency of detection of enthesitis and synovitis was significantly higher than during the clinical examination (p < 0.01). For its part, the psoriatic arthritis activity index (DAPSA) did not correlate with inflammatory changes detected during extensive ultrasound of large joints and entheses according to the “gray scale” and the use of Power-Doppler (p > 0.05). On the other hand, vascularization in the entheses is an index of activity independent of age and activity of psoriatic arthritis and psoriasis (p > 0.05), and it is a sign of active inflammation which correlates with laboratory markers of inflammation (hs-CRP, p < 0.05; ESR, p < 0.01).

Objectives. Improvement of early diagnosis of psoriatic arthritis based on clinical data, immunological and mathematical research methods. Material and methods. The study was carried out between 2019 and 2022 at the Rheumatology and Nephrology Discipline, in the arthrology and rheumatology departments of the Timofei Moşneaga Republican Clinical Hospital. To accomplish the tasks set out in the study, 110 patients were examined, including 55 patients with psoriatic arthritis (group I) and 55 patients with rheumatoid arthritis (group II). Results. The range with the highest probability of psoriatic arthritis for the instrumental index is between 0.54 and 1.86. Of the 55 patients with psoriatic arthritis in 95% of patients clinical, laboratory, immunological and instrumental indices were within the range of the highest probability of the disease, which indicates a fairly high reliability of the mathematical model. Conclusions. Immune disorders in the early stages of rheumatoid arthritis and psoriatic arthritis are nonspecific and are characterized by an increase in CD16+ (26.2±1.5) and CD29+ (24.8±2.1) in rheumatoid arthritis, which is significantly higher than in psoriatic arthritis CD16+ (22.0±1.3) and CD29+ (17.4±3.2) (p <0.05). A mathematical model of rheumatoid arthritis and psoriatic arthritis has been developed, which serves as an additional way of diagnosing rheumatoid arthritis and early psoriatic arthritis. Keywords: rheumatoid, psoriatic arthritis, mathematical, immune diagnosis.

Background. Pachydermoperiostosis (or primary hypertrophic osteoarthropathy) is a rare genetic disease that usually begins in childhood or adolescence, is characterized by certain clinical signs (pachydermia, periostosis, drum sticks) that gradually progress over many years until the disease stabilizes. Currently, there are 2 genes in which mutations are associated with the development of pachydermoperiostosis - HPGD and SLCO2A1. The functions of these genes are not fully understood, but their influence on the metabolism of prostaglandin E2 is known. Case presentation. We present a case of a 20-year-old patient mistakenly diagnosed as juvenile idiopathic arthritis. Symptoms on admission to the hospital: pain accompanied by swelling in the hands and feet, arthralgias in the talocrural joints, knees with slight swelling, paresthesia in the extremities, hyperhidrosis, fatigue. Clinical and paraclinical examinations confirmed the diagnosis of pachydermoperiostosis. Conclusions. Pachydermoperiostosis should be considered as a differential diagnosis when a patient presents with hypertrophic osteoarthropathy and acromegalic features.

Introduction. Psoriatic arthritis (PsA) is a chronic musculoskeletal and cutaneous inflammatory disease that affects about 20-30% of patients with psoriasis. In addition to musculoskeletal and cutaneous manifestations, patients with PsA have a higher prevalence of comorbidities compared to the general population. More than half of patients with PsA have at least one comorbidity, with up to 40% of patients having more than three comorbidities. Purpose of the study. To evaluate the relationship of cardiovascular comorbid pathology with the clinical and laboratory characteristics of the evolution of psoriatic arthritis and quality of life to optimize patient management tactics. Material and methods. In order to achieve the purpose and objectives of the study, a group of 92 patients with psoriatic arthritis was selected, established in accordance with the CASPAR diagnostic criteria (2006). The patients were treated in the rheumatology and arthrology departments of the Republican Clinical Hospital „Timofei Moşneaga„ and of the Municipal Clinical Hospital „Saint Trinity” in Chisinau during 2017-2019. In order to achieve the purpose and objectives of the research, type 1 cohort study (prospective study with retrospective components) is planned. Results. In the study conducted by us in the 92 patients with PsA, different subjective and objective symptoms of heart damage were determined. This number does not include persons up to 18 years of age and after 60 years, with obesity (BMI > 25 kg/m2 ), diabetes mellitus type I or II, hypertension and ischemic heart disease developed up to the onset of the underlying disease, congenital dyslipidemia, congenital and rheumatic valvulopatii, decompensated cirrhosis of the liver, long-term treatment with glucocorticosteroids (>1 month) or > 1 mg/kg/body (for 2 weeks). The most common pathology was hypertension with a frequency of 38% (35 out of 92). With an established diagnosis of coronary heart disease: exertion angina pectoris - at 5.4% (5 out of 92) and postinfarct cardiosclerosis (CSPI) in 2.2% (2 out of 92) of patients, chronic heart failure (ICC) in 6.5% (6 out of 92) of patients. Combined cardiovascular pathology was observed in 16.3% (15 out of 92) of patients. Cerebrovascular disorders were detected in 3.3% (3 out of 92). Conclusions. In patients with PsA of young and middle age, a high frequency of comorbid pathology was observed: in 60.9% of patients, more than one comorbid pathology was observed, with the highest frequency were recorded diseases of the musculoskeletal system (42.4%), cardiovascular (41.3%) and diseases of the digestive system (41.3%).
