Purpose: To increase awareness of ocular pythiosis by presenting a typical case and summarizing clinical data of 11 ocular pythiosis cases in Ramathibodi Hospital.
Design: Interventional case report.
Methods: A 48-year-old healthy woman with a history of 3-week painful corneal ulcer of left eye was treated with enucleation.
Results: The histopathology of enucleated eye revealed endophthalmitis and ulcerative keratitis with numerous hyphae in full-thickness of corneal stroma. The culture identification of the causative organism was Pythium insidiosum. The final diagnosis was ocular pythiosis.
Conclusions: Pythium insidiosum is a causative agent of pythiosis and is distributed worldwide. Ocular pythiosis may not be uncommon, as it may be underdiagnosed due to unfamiliarity among clinicians and microbiologists. Diagnosis of pythiosis is difficult. The disease has high morbidity, as evidenced by nearly evisceration or enucleation among all patients at Ramathibodi Hospital. Early detection and effective treatment are needed for possible cure.

Functional characterization of macrophages and change of Th1/Th2 balance in patients with pythiosis after Pythium insidiosum antigen immunotherapy.

There has been limited research into the role of the Pythium insidiosum antigen (PIA) in modulating immune response in patients with pythiosis. This study investigated the balance of T helper type 2 (Th2) and T helper type 1 (Th1) responses after receiving PIA immunotherapy in patients with pythiosis. Next, the phagocytic activity and phagocytic index of IFN-γ primed PIA-treated macrophages were examined.

Introduction: keratitis (PIK) is a rapidly progressing ocular disease predominantly found in tropical and subtropical regions. Characterized by severe corneal damage and high morbidity, this infection poses significant challenges in diagnosis and management, necessitating effective anti-infective therapies.
Areas Covered: This report delves into the pathophysiology, clinical and microbiological diagnosis, and detailed insights into the anti-infective therapy for PIK, outlining current diagnostic challenges that complicate treatment.

Background: Lagenidium deciduum is an oomycete that can cause infections in mammals that present similarly to pythiosis and mucormycosis. Most of the existing case reports have occurred in canines and have been fatal. In animals, medical therapy has not been successful, so surgical excision is the mainstay of treatment.

Pythium insidiosum keratitis (PIK) is a devastating corneal infection resulting in blindness in a large number of cases. Clinically and morphologically, it closely mimics fungal keratitis, and hence is also labeled as "parafungus." Although many clinical studies have documented evidence regarding the virulence of microorganism, and anatomical and functional outcomes, it remains a clinical challenge and diagnostic dilemma for most clinicians.
