Effectiveness of combined plasma cell therapy and costimulation blockade based desensitization regimen in heart transplant candidates.

Background: Desensitization is one of the strategies to reduce antibodies and facilitate heart transplantation in highly sensitized patients. We describe our center's desensitization experience with combination of plasma cell (PC) depletion therapy (with proteasome inhibitor or daratumumab) and costimulation blockade (with belatacept).

Methods: We reviewed five highly sensitized patients who underwent desensitization therapy with plasma cell depletion and costimulation blockade.

Molecular detection and characterization of (PSTVd) infecting Tomato ( L.) in Karnataka State of India.

Potato Spindle Tuber Viroid (PSTVd) is a non-coding, infectious, small, circular RNA known to cause disease in agricultural and horticultural plants. In the present work, an investigation was conducted in the southern districts of Karnataka state to assess the possible pospiviroid infections on tomato plants that are considered natural hosts for viroids. A total of 83 tomato samples showing disease symptoms (virus or viroid-like) along with healthy ones were collected and subjected to viroid detection by conventional Reverse Transcriptase Polymer Chain Reaction (RT-PCR) using universal (Pospi1-RE/Pospi1-FW) and a specific set of primers (3H1/2H1).

Subconjunctival Dirofilariasis Presenting as Orbital Cellulitis.

Human ocular Dirofilariasis is a relatively rare, zoonotic disease, caused by a filarial nematode, Dirofilaria repens. This parasitic infestation usually presents as a subconjunctival nodule with hyperemia. The authors present a case of subconjunctival dirofilariasis in a 91-year-old gentleman, who presented with manifestations of orbital cellulitis.
