Introduction. The incidence and prevalence of gout have increased worldwide in recent decades. Scientists at the Rochester Epidemiology Project (MN, USA) have seen a two-fold increase in the incidence of primary gout (patients without diuretic exposure) over a 20-year period, which ended in 1996. The increase of incidence may be related due to the difficulty and often unsatisfactory treatment options. The aim of the study was to systematize the recommendations on dietary treatment, and medication for patients with gout. Materials and methods. An analytical, qualitative, and secondary study was performed in the form of a synthesis article. 115 sources were identified and analyzed; from this list, 44 sources were selected according to the impact score during the publication period and according to the level of recommendations. Results. 44 articles were included. Most studies were small, retrospective analyses performed in single centers, with concerns for bias. Eleven studies (including five randomized controlled trials) reported improved patient outcomes following pharmacological interventions with known efficacy in gout, including allopurinol, prednisolone, NSAIDs and anakinra. Eight studies reported improved outcomes associated with non-pharmacological interventions: inpatient rheumatology consultation and a hospital gout management protocol. No studies to date have prospectively evaluated strategies designed to prevent re-admissions of patients hospitalized for gout flares. Conclusions. Urate crystals is completely soluble when we can lower the serum level of uric acid to normal values, but this often requires long-term treatment. The early onset of rehabilitation of affected joints helps to reduce the articular inflammatory process, the pain syndrome and it delays the progression of the underlying pathology while improving the quality of life in patients with gout. Further research is needed to enable healthcare providers to individualize and optimize gout treatment strategies, ensuring that patients with gout receive effective, safe, and high-quality care.

Background: Despite the progress made in the study of psoriasis and psoriatic arthritis, their early diagnosis and treatment for practicing physicians continue to be a difficult problem. Material and methods: 100 people were examined, including 70 patients with psoriatic arthritis aged between 18 and 60 years (23 men and 47 women), admitted to the rheumatology and arthrology departments of the Timofei Mosneaga Republican Clinical Hospital 2019-2022 (Favorable opinion of the Committee for Research Ethics, No 21 of 21.12.2019). The control group included 30 people with rheumatoid arthritis. Results: Ultrasound signs of damage to the joint structures were detected, such as synovitis (p=0.26), cartilage changes (p=0.433), enthesopathy (p=0.980) and tenosynovitis, statistically significant differences (p=0.800). Magnetic resonance imaging determined that fluid was the predominant symptom in frequency (n=13, 92.86%), including in the small joints of the hands (n=1, 100%) and feet (n=2, 100%). Conclusions: In large joints, the proliferation of the synovial membrane was detected in 51.67% of the joints and had predominantly high echogenicity. At small joints, synovial proliferation with predominantly low echogenicity occurred only in 6.1% of the joints.

Introduction. Osteitis condensans ilii (OCI) is a condition characterized by benign sclerosis of the iliac bone in the portion adjacent to the sacroiliac joints, which is radiologically manifested by triangular opacities at the level of this portion. Among the clinical manifestations, localized low back or lumbosacral pain is often attested, which is found in the gestational or post-partum period. The pain may worsen during physical exertion or during menstruation and may be accompanied by myalgia. Material and methods. The epidemiological, clinical and paraclinical data were used to highlight this study, followed by the conclusions of multidisciplinary specialists, retrieved from the inpatient medical records of 3 women with OCI, who were admitted for diagnosis and treatment. Results. 3 cases of imaging-determined OCI will be presented, which were initially diagnosed with seronegative spondyloarthritis (SpA). Through them, we would determine the varieties between the OIC forms and their differential diagnosis with SpA. The results of the lab tests do not reveal specific changes, so the markers of inflammation (C-reactive protein, erythrocyte sedimentation rate) were normal. Also, unlike SpA, the marker HLA-B27 is in most cases negativ Conclusions. According to the results of the presented clinical cases, OCI is often confused with sacroiliitis, which leads to misdiagnosing and erroneous treatment tactics. Thus, in order to establish a true diagnosis, it is necessary to collect a detailed history, perform a comprehensive objective examination, which includes the character of the pain and its triggers, the lack of inflammatory lab markers and the radiological presence of the sclerosis areas at the level of the iliac bone, not involving the sacroiliac joints.

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.

Introduction. Parasitic arthritis is associated with infestation of the patient’s body of parasitic species of worms and protozoan microorganisms. Now it has been established that parasitic arthritis can be caused by almost any species of these creatures. The objective of the study was to research the clinical-evolutionary features of cases of parasitic infections associated with damage of the osteo-articular system in helminthic pathologies. Materials and methods. 161 patients were included in the study, which were divided into 3 groups of differentiated observation by the pathogen of infestation and the clinical variant of parasitic arthritis. The first group (97 patients) consisted of patients with parasitic arthritis associated with echinococcosis infestation, the 2nd (31 patients) – patients with parasitic arthritis associated with Toxocara canis and the 3rd (33 patients) included subjects with parasitic arthritis associated with of Giardia lamblia infestation. Results and discussion. Echinococcosis was manifested more often by the axial (65.67%) and peripheral (31.34%) clinical forms, while the mixed form was being extremely rare (2.98%) (p < 0.001). The power of connection with the type of arthritis has reached the degree of statistical significance (p < 0.001). Parasitic arthritis due to Toxocara canis showed an overwhelming predominance of peripheral forms of joint syndrome (70.96%), with an insignificant share of axial (12.9%) and mixed form (16.13%) (p < 0.01), with a connection to the peripheral form of parasitic arthritis (p < 0.01). The clinically developed form of parasitosis caused by Giardia lamblia manifested a predominantly mixed joint syndrome (57.89%), confirming a predominantly peripheral impairment (36.84%) of the axial (5%) with a statistically significant difference (p < 0.05), as well as a connection for the mixed-peripheral form of parasitic arthritis (p < 0.05). Conclusions. Parasitic arthritis is characterized by the diversity of clinical joint manifestations, which fall into 3 clinical variants: induced by infestation with Echinococcus, Toxocara canis and Giardia lamblia, among which giardiasis correlates with a more severe clinical course, followed by echinococcosis and toxocariasis. Despite a large number of painful and inflamed joints that are also associated with an advanced radiological stage of joint damage, parasitic arthritis is characterized by a comparatively diminished articular painful syndrome.
