Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide.
Aim of our study was to assess the clinical and the cytogenetic characteristics in longlivers with osteoarthritis from Precarpathian region (Ukraine).
Methods: Cytogenetic, Clinical
Results: All of the subjects were separated into three groups: І group - 146 longlivers patients who had hypertension and osteoarthritis (ОА); II group - 93 longlivers patients only with ОА. The control (third) group included 130 patients aged 90-102 years without osteoarthritis and hypertension in anamnesis. In the age group more than 95 years, men and women of both groups were significant difference (p<0,05) to be compared with control.
Cytogenetic characteristics of the long-livers with on osteoarthritis showed that most there is a tendency for a higher frequency of chromosomal aberrations in male long-livers and tere are significant difference among control (p<0,05). The number of chromosomes associated in a single cell was significantly higher (p<0,05) in both groups compared to control.
Conclusion: The importance of this study resides, to the best of our knowledge, in the fact that the largest group of patients in Ukraine was analyzed and assessed.
Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage on the ends of your bones wears down over time. Osteoarthritis is a topic covered in the ICD-10-CM (M15-19). The pathogenesis of OA is not fully understood but some of the factors which contribute towards the development of OA include genetics, obesity, joint injury and occupational factors [5,7,14].
The most common symptoms of osteoarthritis are stiffness, particularly first thing in the morning or after resting, and pain. Some people also experience swelling, tenderness and a grating or crackling sound when moving the affected joints [1,5,16].
Globally, as of 2010, approximately 250 million people had osteoarthritis of the knee (3.6% of the population). Hip osteoarthritis affects about 0.85% of the population [2,13]. As of 2012, osteoarthritis affected 52.5 million people in the United States, approximately 50% of whom were 65 years or older . It is estimated that 80% of the population have radiographic evidence of osteoarthritis by age 65, although only 60% of those will have symptoms [5,13,17].
In Ukrainian population, the prevalence of symptomatic OA was 34.2%, presenting a difference in sex and region (higher in rural areas than in urban areas) [4,11]. In 1997, 42.2 thousand cases of osteoarthritis were diagnosed in Precarpathian region, and in 2014 it was 53.2 thousand .
The proportion of older people is constantly increasing in most industrialized countries. For instance, while 21% of the German population were 65 years or older in 2013, it is expected that at least every third person will be older than 65 years by 2060 and there will be twice as many people aged 70 or older as there are births in Germany . Physical activity reduces joint pain in older adults with osteoarthritis, and helps them to maintain or improve functioning [5,10,18].
Zengini E et al. performed a genome-wide association study for osteoarthritis using data across 16.5 million variants from the UK Biobank resource. Following replication and meta-analysis in up to 30,727 cases and 297,191 controls, they reported 9 new osteoarthritis loci, in all of which the most likely causal variant is non-coding .
The main objective of the EPOSA study is to investigate the personal and societal burden of OA and its determinants in 669 older adults (65-85 years) in five European countries (Germany, the Netherlands, Spain, Sweden, and the United Kingdom). .
Because osteoarthritis is a leading cause of disability worldwide and carries a substantial public health and health economics burden, that aim of our study was to assess the clinical and the cytogenetic characteristics in longlivers with osteoarthritis from Precarpathian region (Ukraine).
This retrospective study evaluated 369 longlivers from Precarpathian region (West Ukraine) who were diagnosed and followed-up at the underwent karyotyping over a period of 16 years (1998–2014) in the Genetic Laboratory of the State Medical University “Ivano-Frankivsk National Medical University”, Ukraine.
Our study were conducted in compliance with the main provisions of the GCP (1996), the Council of Europe Convention on Human Rights and Biomedicine of 04.04.1997, the Helsinki Declaration, Orders of the Ministry of Health of Ukraine.
All of the subjects were separated into three groups: І group - 146 longlivers patients who had hypertension and osteoarthritis (ОА); II group - 93 longlivers patients only with ОА. The control (third) group included 130 patients aged 90-102 years without osteoarthritis and hypertension in anamnesis.
The exclusion criteria included the patients with birth defects or hereditary pathology, cancer, somatic pathology grade III or more.
The examination was carried out on the basis of the therapeutic department №1 and №2, the rheumatologic department of the Central City Clinical Hospital, the department of arterial hypertension of the Regional Clinical Cardiology Clinic in Ivano-Frankivsk and the rheumatologic department of the Ivano-Frankivsk Regional Clinical Hospital, and further observation was carried out outpatient.
At baseline we collected data in person with a socio-demographic questionnaire (e.g., age, socioeconomic status, education). All patients were interviewed in a clinical center, using a standardized questionnaire and a clinical exam. A medical health history questionnaire to ascertain information about major comorbidities (e.g., diabetes, hypertension, cardiovascular disease) was administered.
The osteoarthritis confirmed by reference to the medical records of the orthopaedic surgeon and the original radiographs when possible. Osteoarthritis diagnosed according to the criteria of the American College Rheumatologists and European Criteria (ESCEO, 2014) based on clinical and radiological changes and consultation of the rheumatologist in older patients.
To study the peculiarities of karyotype in OA, a sample of 188 longlivers was created taking into account their desire and health at the time of blood collection.
For cytogenetic analysis, peripheral blood was used as biological material. Two milliliters peripheral blood was drawn in a sterilized syringe under complete aseptic conditions. Rest of the blood was transferred in heparinized vial. Add 5 ml of either PB-MAX Karyotyping Medium of KARYOMAX to each sterile T-25 flask to be set up for the assay. Add 1 ml blood to each tube. Incubate flask in CO2 incubator for 48-68 hours with caps loose. Add 0.1 µg/ml COLCEMID to each flask for a 30 minute incubation. After 15 minutes, transfer flask contents to a 15 ml centrifuge tube and spin down at 1200 rpm for 5 minutes. Remove supernatant and re-suspend pellet. Add 10 ml of 0.075 M KCI to pellet and gently mix. Allow to sit at room temperature for 15 minutes Add 0.5 ml of fixative (three parts absolute methanol to none part glacial acetic acid). Gently mix with pipette. Centrifuge for 5 minutes at 1200 rpm. Aspirate off supernatant. Add 10 ml of fixative, mix and let sit at room temperature for 15 minutes. Repeat centrifugation step. Add 5 ml of fixative, mix, and let sit 10 minutes at room temperature. Centrifuge and aspirate off supernatant. Add 5 ml of fixative and incubate for 10 minutes at 4°C. The cytogenetic karyotype was analyzed on lymphocytes cultured from human peripheral blood. A minimum of 30 metaphases was accepted and analyzed through GTG banding with 450-550 band resolutions observed on microscope (Axiostar plus, Carl Zeiss, Germany) [6,8]. Cytogenetic analyses were performed on phytohaemagglutinin-stimulated lymphocytes according to standard protocol [6,12].
Determined the immunocytogenetic status of the organism, the frequency of association of acrocentric chromosomes, structural and quantitative chromosomal aberrations according to the criteria . The evaluation of AAC included the absence of an overlap of acrocentric chromosomes, the orientation of short shoulders, and the distance between the acrocentrics without satellite, which did not exceed the size of the long shoulder of the chromosome from group G.
Calculated associative index, as the ratio of the number of cells with associations to the total number of analyzed cells, in a 100% calculation. Also the average number of AAC in a single cell and the average number of chromosomes in one association were determined .
We considered the following data for each patient: age at diagnosis of OA, age at the time of the study, medical history and karyotype. Clinical history was recorded too.
In Precarpathian region (West Ukraine) according to the Statistical Office on January, 2015 population  was 1,382,600 persons, including 727,800 women (52.6%).
We studied the cohort of patients came from 14 districts of Ivano-Frankivsk region and Ivano-Frankivsk town (1998–2014 yy). Our cohort included 369 long-livers aged 90-102 years - 239 longlivers with OA and 130 longlivers without this pathology. We observed significantly (p<0,05) more likely 244 (66,1%) female than 125 (33,9 %) men and aged 90-102 years.
Among 369 patients, 298 long-lived people aged 90-95 (80,8%), 67 people (18,2%) over 95 years old, 4 long-lived people (1,1%) were more than 100 years old (Table 1). In control and group II we have not seen any woman over 100 years of age. We observed only two women aged 101 and 102 years in group I, who had osteoarthritis and hypertension. Man aged 102 years only with osteoarthritis was the oldest in our cohort.
Among 146 longlivers (group I) with hypertension and osteoarthritis the median of age was 95±4.8 years, II group - 93 longlivers patients only with ОА (median of 94±4.1). The mean age of the patients in control group was 93±3.9 years. Although no significant difference was found with regard to the age of the groups (p>0.05) under investigation, however, the greatest age at the time of examination was in patients with OA and hypertension compared with the control group. This explained by the fact that patients of group I had health problems and more often turned to doctors than longlivers without any complaints.
In the age group of 90-95 years, prevailed women from the control group – 80 (92,0%) and men from the group II (only with OA) – 24 (80,0%) however, no significant difference was found (p>0,05).
In the age group more than 95 years, men and women of both groups were significant difference (p<0,05) to be compared with control. More than 95 years old, women -18 (28,6%) from the group II (only with OA) most often also met (p<0,05). Among men in the age group over 95 years the least diagnosed OA in group II (only with OA) -5 (16,7%), among women – in group I (osteoarthritis and hypertension) -23 (24,5%).
Three long-livers (two woman and one man) of the age over 100 had a combination of osteoarthritis and hypertension.
At the time of the survey in two groups (I and II) duration of OA was from 15 to 38 years, on average (29,4 ± 8,1) years, in group I duration of HD was from 10 to 35 years, on average (17,2 ± 6,9) years.
Studying the peculiarity of process of osteoarthritis at the Precarpathian long-livers it has been found out, that the beginning of manifestation of diseases at them starts mostly at the age of 75-89 years old, which for long time had been preserving them active physical state. One man from group I aged 95, had surgery on hip twenty years ago due to osteoarthritis. Woman from group II aged 91 was operated nine years ago due to knee osteoarthritis. Both long-livers have tried non-surgical treatments for several years, and they aren’t enough to cope with the pain, swelling, stiffness, and other symptoms of OA and the doctor recommended them to make an operation.
During this period, long-livers with osteoarthritis diagnosed in the Genetic Laboratory of the State Medical University “Ivano-Frankivsk National Medical University”, Ukraine, with various complaints and clinical manifestations.
To study the peculiarities of karyotype in diseases with hypertension and OA, a sample of 188 long- livers (76 men and 112 women) was created taking into account their desire and health at the time of blood collection. In long-livers patients with OA, the differences from the frequency of chromosomal aberrations in persons of the control were not significant (p>0,05) among men (2.57 ± 0.24) and among women (2,33±0,29), respectively (Table 2).
As can be seen from the data in table 2, there is a tendency for a higher frequency of chromosomal aberrations in male long-livers and tere are significant difference among control (p<0,05). In women of both groups, no significant difference was found in comparison with control (p>0,05).
The number of disorders of the hereditary apparatus at the chromosomal level was more often recorded in comorbid conditions, both in men and in women but there was no significant difference among control (p>0,05).
A natural continuation of the study of adaptive possibilities and immunogenetic status of the organism was the study of association of acrocentric chromosomes. It has been established that the average number of associations of acrocentric chromosomes (Table 3) in long- livers patients with hypertension and OA prevailed in the control group (p<0,05).
As can be seen from the data in table 3, the total frequency of AAC cells was not significantly different in the various groups of long-livers, although it was at the highest with comorbidity. The number of chromosomes associated in a single cell was significantly higher (p<0,05) in both groups compared to control.
The average amount of AAC in a single cell in long-term residents with a combination of osteoarthritis and hypertension was 1.75 times higher (p <0.05) compared with those in healthy subjects. It was interesting that the average number of AAC in one cell was almost identical in the case of hypertension or OA, and did not differ significantly from that of healthy long-livers.
All investigated long-livers often found deletions. Their number prevailed in people with comorbid pathology. At the same time, there were more gaps in such long-livers, than in healthy subjects. With a true gap between the fragment and the chromosome there was no connection, one of the fragments on the metaphase plate looked displaced.
To investigate the distribution of associations of acrocentric chromosomes between different chromosomes in long-livers individuals, a statistical analysis was used (Table 4). Between 13-15, 14-22 and 21-22 chromosomes of the association in the first study group compared to the control (p<0.05).
A greater number of cytogenetic disorders (predominance of chromosomal aberrations, AAС) in lymphocytes of long-lived peripheral blood with diseases of hypertension and OA have been established compared to those in long-livers without HD and OA.
We evaluated 239 long-livers with on osteoarthritis and 130 longlivers without this pathology aged 90–102 years from Precarpathian region (West Ukraine) who were diagnosed and followed-up at the underwent karyotyping over a period of 16 years.
Although no significant difference was found with regard to the age of the groups (p>0.05) under investigation, however, the greatest age at the time of examination was in patients with OA and hypertension compared with the control group. This explained by the fact that patients of group I had health problems and more often turned to doctors than longlivers without any complaints.
Cytogenetic characteristics of the long-livers with on osteoarthritis showed that most there is a tendency for a higher frequency of chromosomal aberrations in male long-livers and there are significant difference among control (p<0,05).
The number of chromosomes associated in a single cell was significantly higher (p<0,05) in both groups compared to control.
