Ultraviolet-A1 (UV-A1) wavelengths have been found effective in mitigating signs and symptoms of disease activity in systemic lupus erythematosus (SLE) but studies have been uncontrolled. To rigorously assess the effectiveness and safety of daily low-dose UV-A1 irradiation as a therapeutic agent in this disorder we enrolled 26 women with SLE in an 18-week two-phase study. During the initial six-week prospective, double-blind, placebo-controlled phase, the patients were divided into two groups; Group A was exposed to 60kJ/m2 of UV-A1 (340-400 nm) irradiation within a sunbed five days a week for three weeks and Group B was exposed for an equal amount of time to visible light of greater than > 430 nm (placebo). Each group was then crossed over for exposure to the other source for three weeks. During the second phase-2 weeks-patients and physicians were unblinded and patients were irradiated with progressively decreasing levels of UV-A1 only. Twenty-five patients completed the six-week placebo-controlled phase of the study and eighteen patients participated for the entire 18 weeks. In Group A the systemic lupus activity measure (SLAM) score improved significantly after three weeks of five-day-a-week UV-A1 irradiation (P < 0.05), regressing to baseline during the three weeks of placebo irradiation. Improvement recurred and progressed with six weeks of three-day-a-week UV-A1 irradiation (P < 0.05). Group B patients responded negligibly to the three weeks of visible light, more sharply to UV-A1, and as with Group A, maximally to the six weeks of three-day-a-week UV-A1 (P < 0.01). With twice- and then once-weekly UV-A1 irradiation the SLAM scores worsened slightly. All patients decreased their drug use. Anti-double-stranded DNA antibodies (anti-dsDNA) decreased significantly (P < 0.05) and anti-nuclear antibodies non-significantly. Side effects were negligible. Visible light had no significant effect. In conclusion, low-dose UV-A1 irradiation effectively, comfortably, and without apparent toxicity diminished signs and symptoms of disease activity in SLE.

Summary:Breast cancer patients with cardiac disease are usually excluded from clinical trials of high-dose chemotherapy. We treated 52 patients with inflammatory and/or metastatic disease with sequential high-dose melphalan and stem cell rescue followed by high-dose thiotepa and stem cell rescue. Stem cells were mobilized with cyclophosphamide and/or paclitaxel and filgrastim. Left ventricular ejection fraction (LVEF) was measured by equilibrium radionuclide angiocardiography (ERNA) at baseline, after each course of chemotherapy and 4 weeks after completing both transplants. The mean absolute decrease in LVEF after the two transplants was 3.6% (P ‫؍‬ 0.008 for the comparison with baseline LVEF), and most of this drop (؊2.5%, P ‫؍‬ 0.007) occurred after mobilization. Unexpectedly, paclitaxel was associated with a mean absolute decrease in LVEF of 3.4% (P ‫؍‬ 0.032, n ‫؍‬ 19), cyclophosphamide alone was not associated with a significant change in LVEF (؊1.3%, P ‫؍‬ 0.23), but mobilization with sequential paclitaxel and cyclophosphamide resulted in a mean absolute drop of 4.9% in LVEF (P ‫؍‬ 0.009). Twelve patients were found to have a reduced LVEF (Ͻ50%) at least once during treatment and had a mean absolute decrease in LVEF of 10% (P ‫؍‬ 0.008) from baseline, compared with a drop of only 1.8% (P ‫؍‬ 0.176) in the patients without impaired LV function. Although two of these 12 patients developed symptomatic heart failure, their cardiac symptoms were easily treated and there were no cardiac deaths. We conclude that our protocol has acceptable cardiac toxicity and breast cancer patients with impaired LV function should not be denied high-dose chemotherapy if otherwise indicated.
