Возрастные особенности заболевания не изучены.</p><p>Цель исследования — изучение возрастных особенностей БДПК.</p><sec><title>Материал и методы</title><p>Материал и методы. Ретроспективно было проанализировано 113 пациентов (54 мужчины и 59 женщин), получавших стационарное или амбулаторное лечение в ФГБНУ НИИР им. В.А. Насоновой. Критерии включения: возраст старше 18 лет, кристалл-верифицированный диагноз БДПК, подписанное информированное согласие. Пациенты были разделены на две группы: старше 55 лет (n=38) и моложе 55 лет (n=75). Сравнивали частоту клинических симптомов, в том числе фенотипов в соответствии с рекомендациями EULAR, интенсивность боли по визуальной аналоговой шкале (ВАШ), потребность в симптоматической терапии, частоту выявления хондрокальциноза (ХК) в коленных и лучезапястных суставах по результатам рентгенографии, антропометрические показатели, лабораторные показатели [сывороточный уровень С-реактивного белка (СРБ), креатинина, мочевой кислоты, паратгормона, магния, фосфора, общего кальция], наличие факторов, ассоциирующихся с БДПК [травмы суставов в анамнезе, семейные случаи ХК, гипомагниемия, ги-перпаратиреоз (ГПТ), гемохроматоз, гипомагниемия, ревматоидный артрит (РА), подагра, хроническая болезнь почек (ХБП) &gt;3-й ст., факт приема мочегонных препаратов].</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Из 113 обследованных пациентов с БДПК 38 (33,6%) были моложе 55 лет. Наиболее частым клиническим вариантом БДПК являлся хронический артрит (n=54; 47,8%), реже — остеоартрит (ОА) с кристаллами пирофосфата кальция (ПФК; n=35; 31%) и острый артрит (n=24; 21,2%), их частота в сформированных группах не различалась.</p><p>Интенсивность боли по ВАШ у больных старше 55 лет была больше, чем в более молодом возрасте (50 [40; 70] и 40 [25; 54] мм соответственно; р&lt;0,001); они чаще были вынуждены принимать нестероидные противовоспалительные препараты (НПВП) и/или колхицин (94,7 и 76,3% соответственно; р=0,0039) и имели более высокий сывороточный уровень СРБ (4,1 [1,9; 10,3] и 2,1 [1,9; 10,3] мг/л соответственно; р=0,0034), однако количество пациентов с концентрацией СРБ &gt;5 мг/дл в обеих группах было сопоставимым. Семейные случаи БДПК были зафиксированы у двух пациентов моложе 55 лет. ХК по данным рентгенографии коленных суставов выявлялся у 65 (57,5%) пациентов после 55 лет — достоверно чаще, чем в более молодом возрасте (68 и 36,8% соответственно; р=0,001). При рентгенографии кистей ХК обнаружен у 21 пациента (18,6%), он также чаще встречался после 55 лет (25,3 и 5,3% соответственно; р=0,001).</p><p>К числу факторов, ассоциирующихся с БДПК, относят ОА, подагру, гиперпаратиреоз, РА и ХБП &gt;3-й ст.; в настоящем исследовании они были выявлены соответственно в 91 (80,5%), 28 (24,8%), 14 (12,4%), 5 (4,4%) и 12 (11%) случаях. Значимых различий по частоте выявления этих заболеваний у больных моложе и старше 55 лет не было. Также по одному пациенту имели гипомагниемию и гемохроматоз, оба были моложе 55 лет.</p></sec><sec><title>Заключение</title><p>Заключение. Распространенность БДПК в молодом возрасте может быть недооценена: 33,6% наших пациентов с БДПК, подтвержденной выявлением кристаллов ПФК в синовиальной жидкости, были моложе 55 лет. При этом частота отдельных фенотипов и основных факторов, ассоциирующихся с БДПК, в разных возрастных группах идентична. В возрасте старше 55 лет БДПК характеризуется более частым выявлением рентгенологических признаков ХК, большей потребностью в приеме НПВП и колхицина, большим уровнем СРБ.</p></sec></abstract><trans-abstract xml:lang="en"><p>Calcium pyrophosphate deposition disease (CPPD) is more common at an old age. The age-related features of the disease have not been studied.</p><sec><title>Objective</title><p>Objective: to study age-related features of CPPD.</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. A total of 113 patients (54 men and 59 women) who had received inpatient or outpatient treatment at the V.A. Nasonova Research Institute of Rheumatology were retrospectively analyzed. The inclusion criteria were age older than 18 years, crystal-verified diagnosis of CPPD, and a signed informed consent.</p><p>The patients were divided into two groups: 1) older than 55 years (n=38) and younger than 55 years (n=75). The investigators compared the frequency of clinical symptoms, including phenotypes in accordance with the EULAR recommendations, the intensity of pain with a visual analogue scale (VAS), the need for symptomatic therapy, detection rates for chondrocalcinosis (CC) in the knee and wrist joints by radiography, anthropometric and laboratory (the serum levels of C-reactive protein (CRP), creatinine, uric acid, parathyroid hormone, magnesium, phosphorus, and total calcium) features, the presence of CPPD-associated factors (a history of joint injuries, family CC cases, hypomagnesemia, hyperparathyroidism (HPT), hemochromatosis, hypomagnesemia, rheumatoid arthritis (RA), gout, chronic kidney disease (CKD) Stage &gt;3, and use of diuretics).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Thirty-eight (33.6%) of the 113 examined patients with CPPD were aged less than 55 years. The most common clinical form of CPPD was chronic arthritis (n=54; 47.8%), the less common forms were osteoarthritis (OA) with calcium pyrophosphate (CPP) crystals (n=35; 31%) and acute arthritis (n=24; 21.2 %); their rates did not differ in the formed groups.</p><p>In patients older than 55 years, the pain intensity according to VAS was higher than that at a younger age (50 [40; 70] mm and 40 [25; 54] mm, respectively; p&lt;0.001); they had more frequently to take nonsteroidal anti-inflammatory drugs (NSAIDs) and/or colchicine (94.7 and 76.3%, respectively; p=0.0039) and had a higher serum CRP level (4.1 [1.9; 10.3] and 2.1 [1.9; 10.3] mg/L, respectively; p=0.0034); however, the number of patients with a CRP concentration of &gt;5 mg/dL was comparable for both groups. Family CPPD cases were recorded in two patients less than 55 years of age. Knee joint radiography significantly more frequently revealed CC in 65 (57.5%) patients aged older than 55 years than that at a younger age (68 and 36.8%, respectively; p=0.001). Hand radiography detected CC in 21 (18.6%) patients, it was also more common in those aged older than 55 years (25.3 and 5.3%, respectively; p=0.001).</p><p>The CPPD-associated factors include OA, gout, HPT, RA, and CKD &gt;3 Stage; these diseases detected in this study were seen in 91 (80.5%), 28 (24.8%), 14 (12.4%), 5 (4.4%), and 12 (11%) cases, respectively. There were no significant differences in the detection rates for these diseases in patients younger and older than 55 years of age. Also, one patient had hypomagnesemia and one patient had hemochromatosis; both were younger than 55 years old.</p></sec><sec><title>Conclusion</title><p>Conclusion. The prevalence of CPPD at a young age can be underestimated: 33.6% of the patients with CPPD confirmed by the detection of CPP crystals in synovial fluid were aged less than 55 years. Moreover, the frequency of individual phenotypes and main CPPD-associated factors is identical in different age groups. At the age of older than 55 years, CPPD is characterized by the more frequent detection of radiographic signs of CC, a greater need for NSAIDs and colchicine, and a high level of CRP.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь депонирования кристаллов пирофосфата кальция</kwd><kwd>хондрокальциноз</kwd><kwd>возраст</kwd><kwd>кристаллы пирофосфата кальция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>calcium pyrophosphate deposition disease</kwd><kwd>chondrocalcinosis</kwd><kwd>age</kwd><kwd>calcium pyrophosphate crystals</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Announ N, Guerne PA.
