RESUMO

BACKGROUND: Patients may receive negative results from a specific IgE (sIgE) test such as the ImmunoCAP (CAP) despite a documented history of systemic reaction to a Hymenoptera sting. Thus, further testing may be required using another serological method or venom skin prick tests to confirm allergy diagnosis and correct species. OBJECTIVE: To evaluate the sensitivity and the specificity of CAP and IMMULITE 3gAllergy (IMMULITE) for detecting sIgE to Paper wasp (WA) and Yellow Jacket (YJ) venoms using patient clinical history as the comparator. METHODS: Sera from 70 participants with a history of systemic reactions (SR) to WA and/or YJ stings were tested using CAP and IMMULITE. Fifty participants from this group had negative results on CAP. To assess specificity, sera from 71 participants who had never experienced either a WA or YJ sting were tested using CAP and IMMULITE. Fifty participants from this group tested positive using CAP. RESULTS: In participants with a history of systemic reaction to a Hymenoptera sting, yet who tested negative for WA and/or YJ sIgE according to CAP, the positivity rate according to IMMULITE was 20-42% using 0.10 IU(A)/mL as the limit of detection (LoD), per the manufacturer's specification. When the LoD for CAP (0.35 IU(A)/mL) was applied to the IMMULITE results, positivity according to IMMULITE was 14-26%. Overall, sensitivity, specificity, and agreement with SR were greater for IMMULITE than for CAP. For YJ: sensitivity (IMMULITE:CAP), 42.8%:28.5%; specificity, 53.5%:39.4%; agreement, 48.2%:34%. For WA, sensitivity (IMMULITE:CAP), 58.6%:28.5%; specificity, 49.3%:47.8%; agreement, 43.9%:38.3%. CONCLUSION: The IMMULITE performed well for detecting sIgE to Hymenoptera venom.

RESUMO

The combination of carboplatin/paclitaxel is commonly used as chemotherapy for advanced non-small cell lung cancer. However, the relatively high incidence of neurotoxicity remains a problem. This study was undertaken to determine whether the fractionated administration regimen can reduce the neurotoxicity. Patients with stage III or IV non-small cell lung cancer were randomized to the nonfractionated (NF) dose group, which received paclitaxel (200 mg/m(2)) and carboplatin (area under the concentration-time curve=6) on day 1, or the fractionated dose (F) group, which received paclitaxel (100 mg/m(2)) and carboplatin (area under the concentration-time curve=3) on days 1 and 8. The cycle was repeated every 3 weeks. Peripheral neuropathy was objectively evaluated by measuring the current perception threshold (CPT) in the median nerve using a neurometer. Fourteen and 13 patients were assigned to the NF and F groups, respectively. The incidence of subjective numbness was significantly lower in the F group (15.4%) than in the NF group (57.1%). The CPT value determined at 2000 Hz showed significant increases in the NF group compared with the pretreatment baseline, but no significant changes were observed in the F group. The response rate was comparable in both groups. The fractionated administration of carboplatin/paclitaxel combination therapy showed a significant reduction in neurotoxicity. Measurement of CPT by a neurometer is a useful tool to evaluate the neurotoxicity of anticancer drugs objectively.

RESUMO

UNLABELLED: Aims/Introduction: When monotherapy with an oral hypoglycemic agent (OHA) is not sufficiently effective for blood glucose control, combination therapy with OHA having different mechanisms of action might be indicated. MATERIALS AND METHODS: In the present study, we compared the efficacy of two options in type 2 diabetes mellitus patients whose blood glucose had not been well controlled with mitiglinide (30 mg/day) alone. A total of 20 patients were included in the study and divided into two groups: group A, in which mitiglinide was given concomitantly with the α-glucosidase inhibitor voglibose (0.6 mg/day); and group B, in which a double dose of mitiglinide was given (60 mg/day). Twelve weeks after changing the medication, HbA1c, glycoalbumin and 1,5-anhydroglucitol (1,5-AG) were measured. In addition, at weeks 0 and 12, a meal tolerance test was carried out, and plasma glucose, insulin, glucagon, active glucagon-like peptide-1 (GLP-1) and total glucose-dependent insulinotropic polypeptide levels were measured. RESULTS: The plasma level of 1,5-AG improved in both groups at week 12. In group A, the plasma insulin level significantly decreased and the plasma active GLP-1 level significantly increased during the meal tolerance test at week 12; thus, bodyweight significantly decreased only in group A. CONCLUSIONS: Our findings suggested that concomitant administration of mitiglinide with voglibose could achieve better glycemic control, particularly in the postprandial period, without bodyweight gain and might have beneficial effects in type 2 diabetic patients at risk of macrovascular complications.
