Superficial transitional cell carcinoma (STCC) of the bladder is usually managed with intravesical bacille Calmette-Guerin. Recombinant human interleukin-12 (rhIL-12) is a heterodimeric cytokine that induces T-cell and natural killer cell proliferation/activation and production of IFNgamma. It has demonstrated preclinical in vivo bladder antitumor activity and no systemic toxicity. This phase 1 study evaluated intravesical rhIL-12 administration in patients with STCC (Tis, Ta, or T1) who had failed at least one prior intravesical therapy or had at least two recurrences of low-grade tumors. Eligible patients had adequate hematologic, renal, and hepatic function and Karnofsky performance status at least 70%. Cohorts of three patients received 5, 20, 50, 100, and 200 microg rhIL-12 (treated n = 15). Each patient received intravesical rhIL-12 weekly for 6 weeks, with a 2-hour bladder dwell. No patient experienced moderate, severe, or life-threatening systemic toxicity. Treatment-related adverse events included dysuria, urinary frequency, urinary urgency, asthenia, pain, hematuria, bladder spasms, and chills. Specific AE incidences were not dose-related. Among 12 patients without visible pretreatment lesions, 7 remained disease-free and 5 experienced recurrence of STCC within the 4-week follow-up period. Three patients with pretreatment Tis or Ta/T1 lesions had persistent disease at posttreatment follow-up. No patients with persistent tumor manifested antitumor response to rhIL-12. Two-hour dwell urine samples and 24- to 30-hour postdose serum samples showed negligible induction of IFNgamma. In summary, intravesical rhIL-12 was well tolerated by patients with recurrent STCC but showed no clinically relevant evidence of antitumor or immunologic effects.

In August 2003, 44 victims were poisoned by chemical warfare agents (CWAs) leaked from five drums that were excavated at a construction site in Qiqihar, Northeast China. The drums were abandoned by the former Japanese imperial army during World War II and contained a mixture of Sulfur mustard (SM) and Lewisite. We carried out a total of six regular check-ups between 2006 and 2014, and from 2008 we added neurological evaluations including neuropsychological test and autonomic nervous function test in parallel with medical follow-up as much as was possible. Severe autonomic failure, such as hyperhidrosis, pollakiuria, diarrhoea, diminished libido, and asthenia appeared in almost all victims. Polyneuropathy occurred in 35% of the victims and constricted vision occurred in 20% of them. The rates of abnormal response on cold pressor test (CPT), active standing test (AST), Heart rate variability (CVR-R), performed in 2014, were 63.1%, 31.6%, and 15.9%, respectively. On neuropsychological testing evaluated in 2010, a generalized cognitive decline was observed in 42% of the victims. Memories and visuospatial abilities were affected in the remaining victims. Finally, a 17-item PTSD questionnaire and the Beck Depression Inventory evaluated in 2014 revealed long-lasting severe PTSD symptoms and depression of the victims. Our findings suggest that an SM/Lewisite compound have significant adverse consequences directly in cognitive and emotional network and autonomic nervous systems in the brain.
