Use of PCSO-524® for Control of Inflammation Caused by Iris Tumorand Uveitis in Cats with Lymphoma and Chronic Kidney Disease

A neutered male Domestic Shorthair cat aged 8 years was infected with FIV and diagnosed with nasal submucosa-T-cell lymphoma that was positive to CD3.

Four months later, tumor of iris and uveitis were found in the left eye. Treatment of inflammation of the left eye included prednisolone acetate 1% eye drop (lnf-oph® 1 %, Seng Thai company; Thailand) qid, doxycycline (Siadocin®, Siam Bheasach; Thailand) PO at the dose 10 mg/kg/day, prednisolone (Prednisolone GPO; Thailand) PO0.36 mg/kg bid.

Two weeks later, the size of tumor remained constant, the inflammation degree was reduced but creatinine level was increased. Administration of oral prednisolone, not the eye drop, was then terminated. Uveitis of the right eye was diagnosed and also fibrin in the anterior chamber and tumor of the iris were found in the right eye. Prednisolone acetate 1% eye drop was prescribed for both eyes.

The inflammation of both eyes still existed after 1 month of the prednisolone treatment. Green Lipped mussel extract, PCSO-524® (VetzPetz Antinol®, DKSH, Thailand), 1 capsule per day was then prescribed as an alternative of steroidal medication for control of inflammation, together with the prednisolone acetate 1 % eye drop in both eyes.

After 30 days of the start of PCSO-524® treatment, the tumor of iris disappeared and the severity of uveitis was reduced in both eyes.

A female spayed cat aged 13 years with chronic renal disease later affected with indolent ulcer, and consequently followed by corneal sequestrum.

After azotemia was controlled, the cat was surgically treated with keratectomy that used conjunctival pedicle graft for suture closure.

The cat received 4mg/kg Tolfenamic acid (Tolfedine®, Vetoquinol, Best Agro; Thailand) for 3 days, 2.5 mg/kg Doxycycline monohydrate (Vibravet®, Zoetis, Thailand) for 2 weeks and 1 tablet per day of New Zealand Green-lipped mussel extract, PCSO-524® (Vetz Petz Antinol®, DKSH, Thailand) for long-term control of inflammation.

The latter was used as an antioxidant and alternative to Non-steroid, which is a contradiction for chronic renal failure.


The cat showed decreased severity of inflammation, normal clinical symptoms, and fine control of azotemia.

It is concluded that PCSO-524® (Vetz Petz Antinol®) can be used to support long-term anti-inflammation treatment and reduce the damage in cats with medical contraindication due to chronic renal disease
