PSIX-12 “Lamarin Saldonum” for the raising of milk production of cows

The aim of the research was to establish the effectiveness of the use of the feed additive “Lamarin Saldonum.” The feed additive contains Japanese kelp, milk thistle, to increase the milk productivity during the milking period. The studies were conducted on 40 cows of the black-and-white Holstein breed at the age of 2–4 lactation and the amount of milk for the last lactation not less than 7,500 kg. The cows were divided into 4 groups (GE1, GE2, GE3, GC) of 10 heads in each. Cows GE1, GE2, GE3 received 30 days before calving daily feed additive in doses of 0.1, 0.2, 0.3 g/kg, respectively, for 60 days. In the GC animals didn’t receive the feed additive (control group). Control milking was performed every 10 days. Using of feed additive in the ration increased milk productivity. In the 1st month of lactation, the average daily amount of milk in GC was 24.00±0.93 kg, which is 7.4%, 19.6% (P < 0.01), 7.4% less than in GE1, GE2 and GE3, respectively. In the 2nd month, the highest average daily amount of milk in GE2 and GE3, which is 13.4% (P < 0.01) and 4.6% more than the GC, respectively. In the 3rd month, the average daily amount of milk in GE1, GE2, and GE3 was 30.22±2.44 kg, 39.57±2.68 kg, 35.11±2.59 kg, respectively, which is 6.8%, 39.9% (P < 0.01), 24.1% more than in GC. The mass fraction of fat in milk in animals GE1, GE2, GE3 was 0.2–0.92%(P < 0.01) higher than in GC. In the second month of lactation, the mass fraction of protein in GE2 was higher by 0.24% (P < 0.01), in GE3–by 0.14 (P < 0.05) relative to GC. At the 3rd month of lactation, the protein content in milk was 0.29% higher in GE2 (P < 0.001) and GE3-by 0.21% (P < 0.001) than in GC.

PSX-B-28 Reproductive function of sows with the using of feed additive “Verva”

The aim of the study was to study the effect of the feed additive “Verva” on the reproductive ability of sows and the recovery of their sexual cyclicity. Fir triterpenic acids are the main active ingredient of the feed additive. The study was conducted on 80 sows of the large white breed. Experimental and control groups were formed: GE (n=50), GC (n=30). GE sows from the 80th day of pregnancy for 30 days were additionally given “Verva” at a dose of 3 g per head per day. GC sows weren’t given the “Verva”. Hunting was detected within seven days after weaning the piglets. Artificial insemination was performed twice and the effectiveness was determined on day 28 by ultrasound. The number, weight of newborn piglets in GE and GC don’t differ significantly. By weaning, 10.94±0.17 heads were obtained from one sow in GE, which is 9.1% (p < 0.01) more than in GC. By weaning, the weight of the nest (total weight of piglets) in GC was 66.72=2.13 kg, which is 7.3% (p < 0.05) less than in GE. The “Verva” has a positive effect on the activation of sexual cyclicity: in GE, 95.3% of animals came to the hunt, and in GC-by 4.4% less. On the 4th day after weaning the piglets, 34.1% of the animals came to the hunt in GE, 40% in GC, on the 5th day–46.3% in GE and 50% in GC. On the 6th, 7th days in GE, 17.1% and 2.1% of sows came to the hunt, and in GC, 10.0% and 0.0%, respectively. The efficiency of artificial insemination in GE was 95.4%, which is 13.5% higher than in GC. The “Verva” has a positive effect on the milk production of sows, preserves their progeny, sexual cyclicity after weaning piglets, increases the duration of economic use of animals.

POS0127 ASSOCIATION BETWEEN HYPERURICEMIA AND OSTEOARTHRITIS

Background:

Objectives:

To evaluate the relationship of hyperuricemia (GU) with the course of knee osteoarthritis (OA) and the components of metabolic syndrome (MS).

Methods:

The prospective study included 107 women aged 40-75 y.o, with a reliable diagnosis of I-III Kellgren J. - Lawrence J. stage of knee OA (ACR), who signed an informed consent. The average age of patients was 59.1 ± 8.9 y.o. (from 38 to 74), the duration of the disease was 9 (4-12) years. The average values of the body mass index (BMI) corresponded to obesity (30.6 ± 5.7 kg / m2), waist circumference (WC) - 93.9 ± 12.1 cm. An individual card was filled out for each patient, including anthropometric parameters, anamnesis and clinical examination data, an assessment of knee joint pain according to VAS, and concomitant diseases. All patients underwent standard X-ray of the knee joints, DEXA scan of the lumbar spine and total hip, and laboratory examination.

Results:

Hyperuricemia was diagnosed in 26.2% of patients. Patients with GU had a higher BMI and WC (p<0.05). X-ray examination revealed significantly larger sizes of osteophytes (p = 0.02) and smaller sizes of the medial space of the knee joint (p = 0.02), while the patients of both groups were comparable in age and duration of OA (Table 1). Patients with GU had a statistically significantly higher bone mineral density (BMD) values were observed in L1-L4 and total hip (p<0.05). MS was almost 2 times more often diagnosed in patients with GU (83.3% vs. 49.2%, RR=1.71, 95%Cl 1.21-2.36, p=0.01). Higher levels of CRP, COMP, leptin, triglycerides (TG), creatinine, ALT and AST were determined in patients with GU (Table 1). Spearman rank ordered correlation coefficients between GU and BMI (r=0.22, p=0.03), WC (r=0.26, p=0.02), MS (r=0.29, p=0.01), and CHD (r=0.21, p=0.04). There were a correlation between GU and the stage of knee OA (X-ray) (r=0.34, p=0.02), the size of medial osteophytes in the femur (mm) (r=0.37, p=0.01) and the medial space of the knee joint (mm) (r=-0.27, p=0.01), BMD L1-L4 (r=0.37, p=0.03) and the total hip (r=0.37, p=0.04). There were also significant positive associations with the following laboratory parameters: CRP (r=0.27, p=0.007), COMP (r=0.25, p=0.05), leptin (r=0.29, p=0.03), creatinine (r=0.45, p<0.0001), TG (r=0.44, p=0.0001), ALT (r=0.32, p=0.002), AST (r=0.25, p=0.02).

Conclusion:

GU may be an aggravating predictor of not only MS-associated diseases such as obesity, dyslipidemia, but also OA. Thus, at high levels of uric acid, more advanced radiological stages of OA, high values of the BMD of the axial skeleton and increased values of CRP, COMP are noted. In this connection, therapeutic interventions of OA in patients with GU should also be aimed at reducing the concentration of uric acid, which may provide a slowdown in the progression of the disease. Further study of this issue is needed.

POS0130 ASSOCIATION BETWEEN HYPERTENSION AND OSTEOARTHRITIS

Background:

Objectives:

To evaluate the relationship between arterial hypertension (AH) and the course of knee osteoarthritis (OA).

Methods:

The prospective study included 109 women aged 38-75 y.o., of I-III Kellgren J. - Lawrence J. stage of knee OA (ACR), who signed an informed consent. The average age was 59.3 ± 8.7 y.o. (from 38 to 74), the average duration of the OA was 7 (4-12) years. The average values of the body mass index (BMI) corresponded to obesity (30.9 ± 5.4 kg / m2), waist circumference (WC) – 94.4 ± 11.7 cm. An individual card was filled in for each patient, including anthropometric parameters, anamnesis and clinical examination data, assessment of knee joint pain according to VAS, WOMAC, KOOS and DN4 indices, and concomitant diseases. All patients underwent standard X-ray of the knee joints, laboratory examination.

Results:

AH was diagnosed in 69.7 % patients with OA. Patients were divided into 2 groups, according to the presence or absence of AH (Table 1). Patients with AH were older, had a higher BMI, WC, a longer duration of menopause and significantly earlier its onset (p<0.05). Patients with OA and AH had a more severe course of OA: higher values of pain in VAS, total WOMAC and all its components, DN4, worse indicators of total KOOS (p<0.05). X-ray examination showed a tendency to a more significant narrowing of the medial space of the knee joints (p = 0.07). Laboratory examination showed higher values of CRP, ESR, IL-6, and leptin (p < 0.05).

We founded positive (р <0.05) associations between AH and a more severe, prolonged course of OA (r=-0.39, p<0.01) in the the Spearman rank-order correlation coefficient analysis. Thus, patients with AH had higher values of VAS pain (r=0.31, p<0.01), total WOMAC (r=0.31, p<0.01) and all its components (pain (r=0.33, p<0.01), FI (r=0.3, p<0.01) and stiffness (r=0.24, p<0.01), DN4 (r=0.24, p=0.01), worse indicators of total KOOS (r=-0.42, p<0.01) and overall health status (r=0.23, p=0.02), more often detected more advanced stage of OA (r=0.24, p=0.03) and synovitis (r=0.23, p=0.01). In addition, positive relationships were found with CRP (r=0.31, p<0.01), IL - 6 (r=0.3, p=0.03), ESR (r=0.3, p=0.02). Positive relationships were confirmed between AH and age (r=0.39, p<0.01), menopause duration (r=0.39, p<0.01), WC (r=0.37, p<0.01), leptin (r=0.35, p=0.01), the presence of hypertriglyceridemia (r=0.35, p=0.01) and cardiovascular risks according to SCORE (r=0.26, p=0.02), considering traditional risk factors for cardiovascular diseases (CVD).

Conclusion:

Thus, we found that AH in patients with knee OA is affected by a variety of variables, both related to traditional CVD factors and to OA itself, and the correlations found are approximately equal in strength. The results obtained require further study, and it is possible that preventive measures aimed at reducing the traditional risk factors of diseases of the circulatory system, or correcting existing CVD, will contribute to a more favorable course of OA.

AB0604 FACTORS ASSOCIATED WITH PAIN IN EARLY KNEE OSTEOARTHRITIS (PRELIMINARY DATA)

Background:

Objectives:

To identify factors associated with pain in patients with early knee osteoarthritis fulfilling ESKOA criteria [1].

Methods:

50 patients (46 women (92%); 4 men (8%)) fulfilling ESKOA criteria were enrolled in the trial, every participant signed up the consent form. Median age of patients was 47 ± 8 yrs (36 – 63 yrs), body mass index (BMI) was 28.5 ± 4.9 kg/m2 (40% of patients had obesity). Every patient, after signing the standard informed consent form, was addressed to a physician, who would fill in an individual case report form (CRF), including anthropometric parameters, history of OA, comorbidities and physical examination data. Knee pain was also assessed with the use of visual analog scale (VAS). All participants underwent knee X-ray according to the standardized fixed flexion protocol with the use of positioning frame [2].

Results:

Most of the patients (70%) were between the ages of 35 and 50 and only 15 of them (30%) were older than 50 years. Median knee pain duration was found to be 16 (12-20) weeks, intensity of VAS – knee pain was 46 mm (42-50). Median number of episodes of knee pain (in the last 6 months) was 3 (2-6); 30 participants (60%) had episodes of knee pain lasting less than a week, 8 of them (6%) had pain lasting for around a week, 12 of them (24%) had episodes of pain lasting more than one week. In most patients (74%) pain relieved with time, without any additional therapy. Most of the patients had episodes of knee pain linked to increased overload (48 (96%)), when squatting (41 (82%)), most of the patients also reported pain when climbing up and down the stairs (80%) and short joint stiffness when starting movement (76%). Knee pain after sitting was reported in 54% of cases and 20 participants (40%) also reported some walking limitations due to knee discomfort.

Knee X-ray revealed that most of the patients had I Kellgren&Lawrence (K&L) stage knee OA (picture 1). All the included participants had ESR (7 (5-10 mm/hr)) and CRP (1.24 (0.8-2.2 mg/l)) within normal range.

Picture 1 – Radiological knee OA stage (K&L) distribution in the study group

In the Spearman correlation analysis, we have estimated the factors, which may be associated with more severe pain in patients with early knee OA fulfilling the ESKOA criteria. We found out that higher BMI (r=0.38, р=0.02), presence of metabolic syndrome (r=0.37, р=0.008) and hypertension (r=0.29, р=0.04), as well as walking limitations (r=0.33, р=0.008) are associated with knee pain.

Conclusion:

The use of ESKOA criteria in patients with short duration of knee pain can facilitate diagnosis of osteoarthritis on an early stage. In addition, the acquired data show that timely diagnosis and correction of certain components of metabolic syndrome may be beneficial for the course of knee pain intensity in patients with early knee OA, further continuation of this trial is necessary.
