Sütçü İneklerde Ovaryum Kistlerinin Tanısı ve Metabolik Profili Üzerine Bir Çalışma

Abstract

A clinical study was performed to evaluate the diagnostic methods for ovarian cysts (OC), and to determine the metabolic profiles of animals with OC in the region of Mitidja in the North of Algeria. A total of 504 non-pregnant lactating cows were used in this study. Ultrasonography was performed by EXAGO scanner and was combined with assessment of serum P4. Biochemical serum parameters were assayed by spectrophotometry and insulin and cortisol serum measurement was performed by electrochemiluminescence. The results showed an overall incidence of 11.9% of OC. The incidence of OC was higher among cows in third lactation. Holstein breed was the most affected by OC compared with other breeds (P<0.001). There were no effects of average BCS (Body Condition Scoring) and milk production on the incidence of OC (P>0.05). OC were single in 91% of cases. They were found mainly on the right ovary (66.66%). Seasonality had a significant influence on incidence rate of OC with higher incidence rates during winter and spring (71.66%); while, 28.33% of OC were detected during the summer and autumn (P<0.05). OC were associated with low serum concentrations of glucose, insulin and urea as well as high levels of cortisol. Ultrasound examination and progesterone assays were proposed as the most effective diagnostic combination to diagnose OC. In conclusion, in addition to hormonal imbalances, metabolic disorders are involved in the formation and/or persistence of OC. Therefore, the use of metabolic indicators in understanding and exploration of OC is of great interest.

Toplam 504 gebe olmayan laktasyondaki inekler bu çalışmada kullanıldı. EXAGO tarayıcı kullanılarak ultrasonografi uygulandı ve serum P4 verileri ile birlikte değerlendirildi. Biyokimyasal serum parametreleri spektrofotometri ile belirlenirken insülin ve kortizol serum ölçümleri elektrokimyasal görüntüleme ile gerçekleştirildi. Ovaryum kist insidansı %11.9 olarak belirlendi. Ovaryum insidansı üçüncü laktasyondaki ineklerde daha fazla oranda tespit edildi. Diğer türler ile karşılaştırıldığında Holstein ırkında ovaryum kisti daha fazla oranda gözlemlendi (P<0.001). Ovaryum kisti üzerine Vücut Kondisyon Skorunun bir etkisi gözlemlenmedi (P>0.05). Ovaryum kisti, vakaların %91'inde tek taraflı olarak tespit edildi. Kistler çoğunlukla (%66.66) sağ ovaryumda yer almaktaydı. Mevsimin ovaryum kistlerinin ortaya çıkmasında önemli bir etkiye neden olduğu, kış ile ilkbahar aylarında (%71.66) insidansın arttığı yaz ve sonbaharda ise düşük seviyede (%28.33) olduğu belirlendi (P<0.05). Ovaryum kistlerinin düşük glukoz, insülin ve üre ile yüksek kortizol serum konsantrasyonları ile ilişkili olduğu belirlendi. Ult...

Evaluation of the Relationship between Type and Amount of Fat Consumption in the Diet and Functional Ovarian Cysts in Females of Reproductive Age

“…The present study found no significant difference in BMI between the case and control groups, although obesity and overweight are established risk factors for FOC. FOCs are among the most common gynecological diseases worldwide, and their prevalence is influenced by lifestyle and nutritional factors, which are also risk factors for other non-communicable diseases [4,13,14]. Given the high prevalence of overweight and obesity among Iranian women of reproductive age [6], it is noteworthy that 20 (50%) case and 23 (57.7%) control participants in our study had a BMI above 24.5 kg/ m 2 .…”

“…Women with a higher BMI can produce more estrogen from steroids in adipose tissue, which has a positive effect on LH production and a negative effect on FSH production. Moreover, an increase in LH levels can cause hyperplasia of the ovarian stroma and an increase in androgen production, ultimately leading to the anovulation cycle in women [13]. Therefore, adopting a proper diet and engaging in appropriate physical activity to lose weight improves insulin levels, insulin resistance, and reduces androgenization, leading to improved ovulation.…”

Influence of Age and Breed on Bovine Ovarian Capillary Blood Supply, Ovarian Mitochondria and Telomere Length

“…The increased vascularization of the superficial cortical stroma in normal older ovaries and in ovaries due to polycystic syndrome could affect the cortical metabolic rate and thus, the survival of the primordial follicles and lead to early follicular growth [25]. Since ovarian cysts in high-performing dairy cows, like the Holstein-Friesian, are also a major factor affecting fertility [28][29][30], these dynamics should be studied more closely. Particular attention should be paid to the spatial distribution of the blood vessels (superficial and deep cortical stroma).…”

Factors Influencing Cystic Ovarian Disease in Holstein Friesian (HF) Crossbred Cattle

“…The incidence of cystic ovarian disease was highest in 2 nd parity and was reduced thereafter, as reported by Roberts [13] . Contrarily, Mimoune et al [14] have reported a higher incidence of COD in 3 rd lactation, Hernendez-Ledezma et al [15] was observed that the incidence of cystic ovary increased from 8.4% in primiparous cows to 25.9% in cows of 5 th lactation. In the present study, no cyst was observed beyond 5 th lactation, which was similar to that reported by Bhattacharyya et al [16] .…”
