Use of PCSO-524® with Physical Rehabilitation to Regain Mobility in Dogs after Femoral Head and Neck Excision


An 8 years old Pomeranian dog showed acute non weight-bearing lameness of the right hind limb after high jumping. Preliminary examination identified pain at the right hip and radiographic images revealed right hip luxation.
Femoral head and neck excision was performed for the surgical treatment.
Multimodal treatment scheme deployed after the surgery consisted of neutraceutical PCSO-524® and physical rehabilitation using laser class 4, exercise such as Cavaletti exercise, balanced board, walking on treadmill, and hydrotherapy including walking under water and swimming.
Evaluation of the treatment during follow-up showed decreased pain score and severity of lameness, which was consistent with the owner’s report that described improvement of weight- bearing of the right hind limb and the quality of life.

Use of PCSO-524® and Cyclosporin for Treatment of Immune-Mediated Polyarthritis in Dogs


An 8 years old Chihuahua dog was admitted to the Small Animal Hospital at Chulalongkorn University due to signs of depression, lethargy, lameness and joint effusion. Hematological examination and test of synovial fluid indicated Immune-Mediated Polyarthritis (IMPA).
Prednisolone, Gabapentin and Amoxillin-clavulanic acid were prescribed for the treatment. Abnormally increase of ALT, ALK and AST enzyme was observed 1 week later, therefore, the treatment was changed to Cyclosporin, Gabapetin, and PCSO-524®. The clinical signs continued to improve after the adjustment of prescription and Cyclosporin and Gabapetin were terminated after 3 and 4 months, respectively.
A follow-up examination at 4 months later showed no signs of lameness and joint effusion and no adverse effects caused by the long-term use of PCSO-524®.
The success of IMPA treatment is a result of rapid diagnosis and appropriate treatment protocol. Follow-up for treatment evaluation is necessary during the treatment course in order to reduce the impact on health and minimize the medication dosage without risk of causing adverse effects or recurrence of the disease.

PCSO-524® for Treatment of Immune-Mediated Polyarthritis in Dogs
An 8-year old Chihuahua dog was admitted for surgical treatment of patella luxation at Small Animal Hospital of Chulalongkorn University, Thailand.
At 2 weeks prior to the hospital visit, the dog showed signs of fever, anorexia, lethargy, and lameness of the left leg. Non-steroidal anti-inflammatory drug (NSAIDs) was prescribed at that time but the dog had no response to the treatment.
The dog received prednisolone 0.6 mg/kg bid, gabapentin 10 mg/kg sid, samylin® liver supplement 1 tablet sid, and amoxicillin-clavulanic acid 20 mg/kg sid in the first week of the treatment. Then prednisolone was stopped due to elevation of liver enzymes; AST, ALT, and ALK.
The following 1-month treatment course included cyclosporine 6 mg/kg bid, gabapentin 10 mg/kg bid, samylin® 1 tablet sid, and PCSO-524® 1 capsule bid.

Use of PCSO-524® Along with Physical Therapy for Controlling Pain and Inflammation in a Cat Suffering from Osteoarthritis, Chronic Kidney Disease and Triaditis
A spayed female domestic shorthaired cat aged 21 years and weighed 4.2 kilograms with history of chronic kidney disease and triaditis was referred to Suvarnachad Animal Hospital.
The cat showed signs of both hind limb weakness, limp tail and pain around posterior body part. Other signs included polydipsia, polyuria, and diarrhea. Radiographic examination revealed osteoarthritis at lumbosacral joint, elbow and both stifle joints. Hematological and blood chemistry tests showed mild anemia, neutrophilic leukocytosis, increased serum amyloid A and Increased Feline pancreatic lipase.
Administration of PCSO-524® and physical therapy were provided to reduce systematic and local pain and inflammation. The supportive treatment was continued for 15 months, during the first 2 months of which, the lumbosacral joint painwas reduced and then disappeared after 5 months. The control of elbow and knee joint pain was satisfied for the whole treatment period.
The cat was able to move the tail and resume normal walking after the 1st and 5th month of the treatment, respectively. Ability to jump and climb returned in the 5th and 8th month. However, the cat had improved defecation within 3 months. Testing of feline pancreatic lipase and serum amyloid A showed normal levels after 7 months of the treatment.

Clinical Effect of PCSO-524® on 3 Osteoarthritic Cats Associated with Chronic Kidney Disease
Three cats suffering from chronic kidney disease were admitted to animal hospital.
The first cat showed sudden onset of right hindlimb pain without apparent cause. Bladder stone was found in the second cat while the third cat was admitted for nursing care. Caging was applied and fluid therapy were administered for the third cat. All 3 cats had never been diagnosed with arthritis prior to the admission.
X-ray examination showed symptoms of arthritis at hip and stifle joints. PCSO-524® was then administered daily for 60 days.
Pain evaluation using Feline Musculoskeletal Pain Index (FMPI), which is a reliable and effective method for pain evaluation in cats (Benito et al., 2013), showed that, after the treatment, chronic pain was decreased in all of the cats (Appendix 1). The cats’ behavior was nearly normal compared with the behavior before the treatment. Interaction between the cats and owners was improved as well.
By the end of the experiment, UP/C ratio was not altered and blood creatinine tended to decrease.

Nutraceutical Treatment of Feline Fhne and Hip Dysplasia in an 8-Month Old Cat
A Persian male cat was diagnosed with right hip luxation and left hip injury. While waiting for surgical treatment, the cat was treated with NSAIDs to control pain and inflammation.
After the operation on the right femoral head (right FHNE), the cat received antibiotics and NSAIDs for 10 and 3 consecutive days, respectively. Two weeks after the operation, the lameness and pain of the right hip, as observed from palpation, still remained, but the cat began to bear partial weight.
PCSO-524® was then prescribed and the gait analysis was performed to measure the angle of joint movement.
The monitoring showed increased angle of joint movement and decreased lameness score. This was consistent with the owner report that described less hiding behavior of the cat and improved high jump performance and better quality of life.

Use of PCSO-524® Combined with Surgical Treatment of Patellar luxation in Dogs
Five dogs with bilateral patellar luxation were presented at the Small Animal Hospital of Faculty of Veterinary Medicine, Chulalongkorn University.
Four dogs had grade 2, 3, and 4 medial patellar luxation in 3, 3, and 2 stifle joints, respectively. One dog had grade 3 bilateral lateral patellar luxation that had recurrent patellar luxation of left stifle joint for 6 months after previous surgery. All dogs had surgical treatment to re-align and stabilize extensor mechanism in the normal position.
The dogs received anti-inflammatory drug and PCSO-524® in combination with rehabilitation to restore normal limb function and muscle mass postoperatively. All dogs achieved good outcomes when compared with pre-operation. Range of motion was normal in all dogs and the patellae were in the normal position.
However, one stifle with previous reluxation and severe osteoarthritis had slightly crepitation when flexed and extended the stifle joint. Patellar luxation causes abnormal wear of the patella and trochlear ridges leading to lameness, muscle pain, and osteoarthritis.
The treatment focuses on stabilization of the stifle joint and restore limb function. Surgical treatment is recommended in most cases. Rehabilitation provides strengthen muscle, improves normal joint function, enhanceslimb function, and prevents complications.
Despite successful treatment for correcting patellar luxation, osteoarthritis remains occurrence in most cases.
Therefore, use of anti-inflammatory supplement such as PCSO-524® is important for long-term management with less side effect and safety for long-term use when compared with non-steroidal anti-inflammatory drugs.


Use of PCSO-524® for Treatment of Spine Fracture in Conjunction with Pedicle Screw-Rod Fixation (PSRF)
An intact male mixed breed dog aged 2 years engaged in a fight with several dogs resulting in disable of hind limbs and loss control of elimination. Physical and radiographic examination showed fracture and luxation of the 7th lumbar vertebrae. Spinal cord injury (SCI) was also found and the fracture was identified as the cause. The spinal cord trauma could occur since the incident and was left for more than 2 weeks.
Pedicle screw-rod fixation (PSRF) was operated to fix the vertebral column. After the second operation, it was suspected that there was remain of inflammatory cytokines that probably increased after the operation. Anti-inflammatory medication for prohibition of inflammatory cytokines synthesis was essential but its adverse effect must be concerned. The study therefore used holistic treatment including PSRF, non-steroidal drug and PCSO-524® anti-inflammatory extract, in conjunction with physical therapy.
Follow-up examination on neurological system, walking, and urinary system showed promising result. The neurological system was restored, and adverse effect of long-term use had not been found.

The Trial Treatment of Feline Osteoarthritis in an Eleven-Year-Old Cat
A domestic short hair cat aged 11 years was taken to the hospital due to shaking and weakened hind legs. The cat could not perform high jump for 1 month.
Preliminary diagnosis included early stage of osteoarthritis of left hip and capsulitis.
Pain killers, NSAIDs and gabapentin, were administered but the response was not satisfied. Therefore, multimodal treatment program was initiated. Physical therapy using electrical stimulation and laser beam class 4 in conjunction with PCSO-524® were used. Measurement of joint movement angle (active range of motion; active ROM) in 2 dimensions using Kinovea program was conducted for follow up.
The study found increased active ROM and decreased lameness score after the treatment.
The owner described that the cat showed less isolation behavior and was able to perform vertical jump again. Overall quality of the cat’s life was improved.

Use of PCSO-524® (Antinol®) for Treatment of Nervous Disorder Caused by Car Accident and Hip Osteoarthritis in Geriatric Cats
Male castrated Persian cat aged 12 years was injured at the rear body in an automobile accident causing paralysis of the hind limbs.
X-ray examination found luxation of both pelvic joints and osteoarthritis of hip joint. Nervous disorder of the hind limbs was diagnosed from the absence of the motor and deep pain sensory impulse. MRI examination found no spinal cord damage.
The treatment included electrical stimulation at the hind limb muscle in combination with long-term administration of PCSO-524® (Antinol®).
The hind limbs were functional normally at the end of the treatment and blood chemistry examination at 32 weeks after the treatment showed normal liver and kidney indicators.
