Influence of initial treatment modality on long-term control of chronic idiopathic urticaria.

ABSTRACT: BACKGROUND: Chronic idiopathic urticaria (CIU) is a common cutaneous disorder but the influence of initial treatment modality on long-term control is not known. The aim of this study was to evaluate clinical features, and the influence of initial treatment modality on long-term control. METHODS AND RESULTS: 641 CIU patients were enrolled from the allergy clinic in a tertiary referral hospital. Disease duration, aggravating factors and treatment modality at each visit were evaluated. Times required to reach a controlled state were analyzed according to initial treatment modality, using Kaplan-Meier survival curves, the Cox proportional-hazards model, and propensity scores. Female to male ratio was 1.7: 1; mean age at onset was 40.5 years. The most common aggravating factors were food (33.5%), stress (31.5%) and fatigue (21.6%). Most patients (82.2%) used H1-antihistamines alone as initial treatment while 17% used a combination treatment with oral corticosteroids. There was no significant difference in the time taken to reach a controlled state between patients treated with single vs multiple H1-antihistamines or between those who received H1-antihistamine monotherapy vs. a combination therapy with oral corticosteroids. CONCLUSION: The time required to control CIU is not reduced by use of multiple H1-antihistamines or oral corticosteroids in the initial treatment.

Project description:ImportanceThe first-line treatment for patients with chronic spontaneous urticaria (CSU), which is divided into idiopathic and autoimmune subtypes, consists of H1-antihistamines. However, limited evidence guides the treatment of CSU after maximal therapy with antihistamines fails. Two randomized clinical trials suggest that dapsone may be a successful second-line therapy.ObjectiveTo evaluate the efficacy and safety of dapsone therapy in patients with CSU.Design, setting, and participantsThis retrospective medical record review included 79 patients with CSU treated with dapsone who presented to the tertiary care academic medical center at the New York University School of Medicine, New York, New York, from January 1, 2005, through April 15, 2017. Follow-up was completed on February 28, 2018. Data were analyzed from March 1 through May 31, 2018.ExposuresTreatment with oral dapsone for CSU.Main outcomes and measuresEfficacy of dapsone therapy for CSU was evaluated as improvement, complete response, and remission.ResultsSeventy-nine patients (65% women; mean [SD] age, 49.8 [16.1] years [range, 20-79 years]) were included in the analysis. Forty-five patients had chronic idiopathic urticaria and 34 had chronic autoimmune urticaria. Improvement in CSU was observed in 62 patients (78%) (36 [80%] with idiopathic and 26 [76%] with autoimmune disease) with dapsone. Mean (SD) time to improvement was 1.1 (1.0) months. A complete response was achieved in 29 (47%) of these 62 patients (16 [44%] with idiopathic and 13 [50%] with autoimmune disease). Mean (SD) time to complete response was 5.2 (5.2) months. Dapsone therapy was tapered in 21 patients after a mean (SD) of 2.4 (2.2) months and discontinued in 18. Ten patients experienced remission with no subsequent flares, even after dapsone therapy was discontinued with follow-up of 0.3 to 10.0 months. Sixteen patients experienced mild adverse effects. Two serious adverse effects were reported.Conclusions and relevanceResults of this study suggest that dapsone is a useful and well-tolerated second-line therapy for patients with CSU in whom antihistamines and other first-line agents have failed.

Project description:ObjectiveTo evaluate the impact of measures of intraocular pressure (IOP) control on progression of visual field (VF) loss during long-term treatment for open-angle glaucoma (OAG).DesignLongitudinal, randomized clinical trial.ParticipantsWe included 607 participants with newly diagnosed OAG.MethodsStudy participants were randomly assigned to initial treatment with medications or trabeculectomy, and underwent examination at 6-month intervals. Standardized testing included Goldmann applanation tonometry and Humphrey 24-2 full threshold VFs. Summary measures of IOP control during follow-up included the maximum, mean, standard deviation (SD), range, proportion less than 16, 18, 20, or 22 mmHg, and whether all IOP values were less than each of these 4 cutpoints. Predictive models for VF outcomes were based on the mean deviation (MD) from VF testing, and were adjusted for age, gender, race, baseline VF loss, treatment, and time. Each summary IOP measure was included as a cumulative, time-dependent variable, and its association with subsequent VF loss was assessed from 3 to 9 years postrandomization. Both linear mixed models, to detect shifts in MD levels, and logistic models, to detect elevated odds of substantial worsening (?3 dB), were used.Main outcome measuresWe measured the MD from Humphrey 24-2 full threshold VF tests.ResultsThe effect of the summary IOP measures differed between the medicine and surgery groups in models that addressed the continuous MD outcome. After adjustment for baseline risk factors, in the medicine group larger values of 3 IOP control measures-maximum IOP (P = 0.0003), SD of IOP (P = 0.0056), and range of IOP (P<0.0001)-were significantly associated with lower (worse) MD over the 3- to 9-year period. No IOP summary measure was significantly associated with MD over time in the surgery group. The same 3 IOP summary measures were also significantly associated with substantial worsening of MD; however, the effects were similar in both treatment groups. In models predicting inadequate IOP control, consistently significant predictors of higher maximum, SD, and range of IOP included black race, higher baseline IOP, and clinical center.ConclusionsThese results support considering more aggressive treatment when undue elevation or variation in IOP measures is observed.
