Abstract

The radioimmunoguided surgery (RIGS) system employs a monoclonal antibody (CC49), a radionuclide (Iodine-125), and a hand-held gamma-detecting probe (the Neoprobe model 1000). The prototype cancer studied has been colorectal cancer. The antibody identifies a type of mucin, the by-product of the adenocarcinoma cancer cell. The RIGS system localizes up to 90% of colorectal cancers and finds additional RIGS-positive tissues in >50% of the patients. More than 90% of the RIGS-positive visceral tumors are identified by routine hematoxylin-and-eosin (H&E) light microscopy, but the RIGS-positive lymph nodes are H&E occult tissues in >70% of the cases. Enhanced, more time-consuming methods have been developed to confirm hidden cancer cells in these lymph node tissues. Survival data confirm the importance of RIGS-positive tissues. RIGS-positive tissues remaining at the completion of the surgical procedure portend a much poorer outcome than if the patient is deemed RIGS-negative at the completion of the surgical procedure (i.e., all RIGS-positive tissue was removed at surgery).

ZrO₂@C-based colorimetric/photothermal dual-mode immunosensor coupled with a novel monoclonal antibody for quantification of Aspergillus ochraceus biomass.

Aspergillus ochraceus contaminates agricultural products and produces nephrotoxic, carcinogenic ochratoxin A (OTA), posing severe food safety hazards. A dual-signal lateral flow immunochromatographic assay (dLFIA) based on ZrO₂@C nanoprobes was established for quantitative detection of A. ochraceus biomass. A novel monoclonal antibody (mAb 4B4) was prepared as the capture antibody to immobilize A. ochraceus mycelial lysate antigen on the test line, and a rabbit polyclonal antibody (pAb G2801) as the detection antibody to modify ZrO₂@C composites (synthesized via UiO-66 pyrolysis) into 200 nm colorimetric/photothermal nanoprobes. This dLFIA achieved limits of detection of 0.164 μg/mL (colorimetric) and 0.517 μg/mL (photothermal). This efficient and reliable method allows quantitative analysis of A. ochraceus biomass, which is suitable for routine monitoring of fungal contamination in agro-food matrices.

Rituximab for lymphoproliferative disease prior to haematopoietic stem cell transplantation for X-linked severe combined immunodeficiency.

Lymphoproliferative disease (LPD) is a complication of congenital and acquired immunodeficiency states. There are a number of treatment options for LPD arising after haematopoietic stem cell or solid organ transplantation including reduction of immunosuppression, targeted therapies, such as the anti-CD20 monoclonal antibody, rituximab, and EBV specific cytotoxic lymphocytes. Treatment of LPD in children with congenital immunodeficiency syndromes remains unsatisfactory and is associated with a high mortality rate. We recently managed an infant found to have polymorphic LPD concurrent with X-linked severe combined immunodeficiency (SCID). Haematopoietic stem cell transplantation (HSCT) had to be deferred because of progressive LPD. Treatment with rituximab resulted in regression of the LPD following which the patient received a 5/6 HLA matched umbilical cord blood (UCB) transplant. The patient remains well 20 months following transplantation. Rituximab treatment may have a useful role in the control of LPD associated with congenital immunodeficiency prior to HSCT.

Response to rituximab in a child with neuroblastoma and opsoclonus-myoclonus.

Opsoclonus-myoclonus (OM) is a paraneoplastic syndrome of probable autoimmune origin. Despite current therapies aimed at decreasing autoantibody formation, OM is difficult to control and may impact long-term neurologic outcome. We present a case of a 19-month-old patient who initially presented with OM, neuroblastoma and a constitutional cytogenetic abnormality t(5;12)(q11.2;q15). The patient's OM was recalcitrant to conventional therapies, but showed significant improvement following treatment with rituximab.
