The aim of this study was to investigate the duration of remission periods in psoriasis after narrowband ultraviolet B (NB‐UVB) phototherapy, especially during multiple cycles of treatment. We analyzed 63 patients (101 cases) demonstrating marked improvement after NB‐UVB phototherapy. The remission period was defined as the duration of time from the end of phototherapy until treatment using either phototherapy or systemic treatments was required again. It was found that an age of 60 years or older, history of systemic therapy within 6 months and three or more phototherapy cycles were significantly associated with shorter remission periods. Furthermore, multivariate analysis confirmed that three or more phototherapy cycles (odds ratio [OR], 4.0; 95% confidence interval [CI], 1.73–9.33; P = 0.001) and a history of systemic therapy (OR, 2.2; 95% CI, 1.27–3.95; P = 0.005) were independently associated with the shorter remission period. In conclusion, when planning NB‐UVB phototherapy for psoriatic patients who have undergone multiple phototherapy cycles, clinicians should consider the possibility of shorter remission periods. 相似文献

The synchronous application of narrowband UVB phototherapy with 311 nm lamps (Philips TL-01) and bathing in Dead Sea salt solution was evaluated in a multicentre trial (n = 60) in outpatients suffering from psoriasis vulgaris. The study design consisted of an initial therapy phase of up to 35 treatments (three to five times a week) followed by maintenance therapy with up to 35 further applications (once or twice a week). Evaluation was performed separately for patients in according-to-protocol (ATP) (n = 280) and intention-to-treat (ITT) (n = 692) groups. An overall significant improvement of the Psoriasis Area and Severity Index (PASI) score (P < 0.05) could be shown for both groups during initial therapy with 71.4% improvement for ATP and 61% for ITT patients. The mean PASI for ATP (values for ITT in parentheses) was 17.7 (18.6) at baseline, 9.5 (10.7) after 20 applications and 5.2 (7.4) at the end of initial therapy. On average, ATP patients received 3.9 (3.5) applications per week with a cumulative irradiation dose of 19.5 J cm-2 (16.2 J cm-2). The most frequent side-effect was erythema, observed in 8.7% of the patients. Subjective evaluation of the therapy by the patients (n = 168) was excellent. Seventy-nine per cent of patients preferred the new treatment strategy in comparison with other previous therapies and 88% regarded this therapy as pleasant and comfortable. In conclusion, we could demonstrate a significant effect of therapy in both the ATP and the ITT groups for this new treatment system which imitates, as far as possible, the Dead Sea climatic conditions, with no severe side-effects and a high acceptance by the patients. 相似文献

The aim of the present study was to examine the effect of far erythemogenic dose of narrow-band ultraviolet B (NB-UVB; starting dose at 35% minimal erythematous dose [MED]) on clinical response by measuring the severity, extent of disease and the changes in quality of life. Fifty patients with chronic plaque-type psoriasis were enrolled. Therapy was held for 3 days a week. The severity of the disease was assessed based on the Psoriasis Area and Severity Index (PASI) score and Dermatology Life Quality Index (DLQI) scores. The percentage improvement of PASI at 30 sessions was 68.99%. The improvement in DLQI scores at 30 sessions was 79.67%. Pearson correlation coefficients showed that PASI scores were not correlated with DLQI scores at the beginning of treatment ( P = 0.330, r = 0.14), but after the 30th session of NB-UVB therapy improvements in quality of life were correlated ( P < 0.05, r = 0.399). Therefore, far erythemogenic dose of NB-UVB is considered to be effective treatment for plaque-type psoriasis in our patients. However, we cannot confirm that it is safer than higher MED starting dose in term of cumulative UV irradiation. 相似文献

We compared the clinical efficacy of various psoriasis treatments among: (i) topical application of calcipotriol ointment twice daily (group I); (ii) topical application of calcipotriol ointment twice daily and narrowband ultraviolet B NB‐UVB phototherapy once a week (group II); (iii) topical application of heparinoid ointment twice daily and NB‐UVB phototherapy more than twice a week (group III); and (iv) topical application of calcipotriol ointment twice daily and NB‐UVB phototherapy more than twice a week (group IV). Ten patients were randomly selected for each group and treated by the indicated regimens for 12 weeks. All treatments were effective and significantly improved Psoriasis Area and Severity Index (PASI) scores, self‐administered PASI scores and visual analog scale scores of pruritus. Group IV showed most marked and rapid reduction in PASI and self‐PASI scores among the four regimens. Although the serum levels of interleukin (IL)‐17, IL‐20 and IL‐22 and psoriasis disability index were significantly decreased after the treatments, no significant difference was detected among the four groups. Our study indicates that combination of calcipotriol ointment plus NB‐UVB more than twice a week is superior to other treatment regimens, rapidly improving psoriasis lesions. 相似文献

Background: A combination of oral psoralen with narrowband ultraviolet B (UVB), defined as 'psoralen-narrowband UVB', was shown to have a superior efficacy than UVB alone and even a comparable efficacy to psoralen and ultraviolet A in psoriasis.
Objective: To find out whether topical psoralen-narrowband UVB provides any additional benefit to narrowband UVB alone in psoriasis.
Methods: Nineteen patients with plaque psoriasis were included. Phototherapy was given three times per week. Two symmetrical lesions were selected as target lesions. In the first 12 sessions of phototherapy, the target lesion on one side was treated with 1% 8-methoxypsoralen (MOP) gel 30 min before UVB radiation whereas the target lesion on the other side served as a control. Target lesion scores were assessed at baseline, third, sixth, ninth and 12th sessions. Side effects were recorded.
Results: Sixteen patients completed the study. Target lesion scores decreased significantly on both sides ( P <0.0001). The mean percentage of decreases was greater on the 8-MOP-applied sides compared with the control sides for all assessments, but the difference was statistically significant only at the ninth session (37.7% vs. 58.6%, P =0.043). Pigmentation was frequently seen in 8-MOP gel-applied lesions.
Conclusion: Topical 8-MOP gel plus narrowband UVB has greater efficacy than narrowband UVB alone in psoriasis. 相似文献

Background: Narrowband ultraviolet B (NB-UVB) phototherapy is an effective treatment for psoriasis.
Objectives: To compare the effects of three and five times weekly NB-UVB phototherapy in the treatment of chronic plaque psoriasis.
Methods: Sixty-five patients with chronic plaque psoriasis were allocated to receive three or five times weekly NB-UVB, starting at low dose.
Results: Among the patients who completed the study, clearance was achieved in 18 out of 23 patients (78%) in the three times weekly group and in 15 out of 22 patients (68%) in the five times weekly group. The difference was not statistically significant ( P =0.44).
No statistically significant differences were found between the two groups in the number of treatments ( P =0.95), cumulative UVB dose ( P =0.51), and rate of side-effects. Length of the treatment period was significantly shorter in the five times weekly group ( P <0.001). At the end of treatment, the mean psoriasis area and severity index score was lower in the three times weekly group ( P =0.02).
Conclusions: We recommend three times weekly NB-UVB for chronic plaque psoriasis; however, the more rapid clearance of psoriasis with five times weekly phototherapy may justify using this method in some patients. 相似文献

BACKGROUND: The use of narrowband ultraviolet (UV) B phototherapy to treat psoriasis and other disorders has increased markedly since the TL-01 lamps were introduced in the 1980s. While broadband UVB phototherapy has generally been considered to be a relatively safe treatment, some concern has been raised about the potential increased skin cancer risk with narrowband UVB. OBJECTIVES: The likelihood of a patient who is free of nonmelanoma skin cancer (NMSC) at the start of phototherapy developing a malignancy after a certain follow-up period will be dependent not only on the carcinogenic potential of the treatment but also on the age-conditional probability of natural occurrence. We were interested to explore the potential difficulty of designing studies to separate these two events. Methods Mathematical models were developed that combined age-conditional probabilities of developing NMSC due to natural causes with the risk of inducing these cancers from narrowband UVB phototherapy in order to estimate the excess number of cancers resulting from this therapeutic intervention in a cohort of patients. RESULTS: Within-department studies will be most unlikely to demonstrate that the number of NMSCs observed in follow-up studies is significantly different from that expected in an untreated population, even for a follow-up period of 20 years. CONCLUSIONS: Determination of the carcinogenic potential associated with narrowband UVB will require large multicentre studies typically involving several thousand new patients per year and followed up for 10 years or more. 相似文献

Background Synchronous balneophototherapy (sBPT) simulates treatment conditions at the Dead Sea for outpatient use. In the past, sBPT proved to be an effective treatment for psoriasis. However, there is a lack of sufficiently large randomized controlled clinical trials evaluating the additional benefit of sBPT compared with ultraviolet B (UVB) monotherapy. Objectives The purpose of this study was to compare the effectiveness and safety of sBPT with UVB phototherapy (PT) alone in a randomized controlled effectiveness study. Methods In this phase III, multicentre effectiveness study, 367 patients with moderate to severe psoriasis were randomly allocated in a 1 : 1 ratio to receive either sBPT consisting of narrowband UVB PT with 311 nm and synchronous bathing in 10% Dead Sea salt solution or PT with 311 nm alone. Primary endpoint, analysed on an intention‐to‐treat basis (n = 356), was the relative improvement of the Psoriasis Area and Severity Index (PASI) from baseline to end of treatment (35 sessions or clearance). Sample size calculation aimed at the detection of superiority of at least 10%. Results Median PASI values were comparable at baseline (sBPT: 15.1, interquartile range: 10.9–24.3; PT: 15.3, interquartile range: 10.0–23.7). A clinically relevant and statistically significant difference of 49.5% between sBPT and PT could be proven at the end of the therapy phase (P < 0.001; Wilcoxon–Mann–Whitney test). Exploratory testing showed a statistically significant superiority of sBPT after 6 months. Conclusions In routine clinical practice, sBPT is superior to PT alone after 35 treatment sessions and a follow‐up of 6 months. Both treatments demonstrated to be safe. 相似文献

Palmoplantar psoriasis is an idiopathic disabling condition, often resistant to conventional therapies. The purpose of this study was to evaluate the efficacy and safety of local narrowband ultraviolet B (NB-UVB) phototherapy and to compare it with local psoralen plus ultraviolet A (PUVA) paint in patients with palmoplantar psoriasis unresponsive to conventional therapies other than phototherapy. A cohort of 25 patients with palmoplantar psoriasis were included in this study, which was based on a left-to-right comparison pattern. The treatments were administered with local narrowband UVB irradiation on one side and local PUVA on the other side three times a week over 9 weeks. Clinical assessments were performed at baseline and every 3 weeks during the 9-week treatment. There was a statistically significant decrease in the mean clinical scores at the third, sixth and ninth week with both treatments. The difference in clinical response between the two treatment modalities was statistically significant at the end of the treatment period, with the percentage reduction in severity index scores with the PUVA-paint-treated side being 85.45% compared with 61.08% for the NB-UVB treated side (t = 5.379, P = 0.0001, Student's t-test for unpaired samples). Our results show that, although some clinical improvement was achieved with local NB-UVB phototherapy, the results were better with local PUVA, and such a treatment option may be reserved for patients with palmoplantar psoriasis who experience phototoxic reaction to psoralens. 相似文献

BACKGROUND: Different protocols have been used for narrowband ultraviolet B (UVB) therapy, commonly used in the treatment of psoriasis; however, more effective and reliable protocols are still required. OBJECTIVE: The aim of this study was to compare the weekly and daily dose increment protocols of narrowband UVB phototherapy in psoriasis patients. METHODS: Thirty patients with plaque psoriasis underwent narrowband UVB treatment three times a week and 15 patients selected consecutively among these patients underwent a weekly (once in three treatments) dose increment whereas the remaining 15 patients underwent a daily dose increment. Patients were monitored for 10 weeks and evaluated by the Psoriasis Area Severity Index (PASI). RESULTS: When the two groups were evaluated according to median PASI scores prior to the treatment and during 10 weeks of treatment, there was no statistically significant difference between the groups (P > 0.05). During the treatment lasting for 10 weeks, four patients in the group with a weekly dose increment and three patients in the group with a daily dose increment recovered and no statistically significant difference was detected between the groups (P > 0.05). The groups were also evaluated according to the median cumulative dose. The median cumulative dose was higher in the group with a daily dose increment and the difference between the groups was statistically significant (P = 0.002). CONCLUSION: The application of daily dose increments was no better than that of weekly dose increments in narrowband UVB treatment for psoriasis. Therefore, although our results may need to be supported by large-series studies, we conclude that application of weekly dose increments with a lower cumulative dose having the same efficacy is preferred in narrowband UVB treatment of psoriasis. 相似文献

Calcipotriol vs. tazarotene as combination therapy with narrowband ultraviolet B (311 nm): efficacy in patients with severe psoriasis 总被引:2,自引:0,他引:2

BACKGROUND: Phototherapy has been shown to be one of the most effective treatment modalities for patients with psoriasis. Nevertheless, photocombination therapies capable both of reducing cumulative ultraviolet (UV) doses and of accelerating clearance of skin lesions are important and of high interest. There have been no published studies comparing the effect of narrowband UVB irradiation in combination with topical application of tazarotene vs. calcipotriol. OBJECTIVES: To determine, in a half-side manner, whether a combination of UVB (311 nm) and tazarotene is superior to UVB (311 nm) plus calcipotriol or vice versa. METHODS: Ten patients suffering from widespread symmetrical psoriasis were treated for at least 4 weeks with topical calcipotriol and tazarotene in a half-side distribution. Additionally, the whole body was irradiated with narrowband UVB (311 nm) four times a week. Before treatment and once weekly during therapy a modified Psoriasis Area and Severity Index was estimated for each body half. The total treatment time, number of treatment sessions and cumulative UVB dose necessary for clearance of skin lesions were determined in an observer-blind fashion for each patient. Furthermore, all patients completed a quality of life questionnaire. RESULTS: Clearance of psoriasis was observed after a median of 19 treatment sessions (range 14-28) and a median cumulative UVB dose of 22.98 J cm-2 (range 9.24-58.22) simultaneously for both body halves. On the side treated with topical tazarotene gel, four patients complained of itching and dryness of the skin, and skin irritation was observed in three of them. Six patients preferred the application of tazarotene gel, while four preferred calcipotriol. CONCLUSIONS: Our clinical comparison of narrowband UVB with either topical calcipotriol or topical tazarotene revealed no significant therapeutic difference between both regimens. Although these results need to be confirmed in larger patient groups, we feel that both photocombination therapies can broaden the therapeutic options for moderate to severe psoriasis vulgaris and may reduce the cumulative UVB dose during therapy. 相似文献

Severe pustular psoriasis von Zumbusch type is a therapeutic challenge not only in adults, but even more in children. We report a 3(1/2)-year-old boy who developed a generalized flare of diffusely scattered pustules on erythematous skin which rapidly progressed to large exuding areas. The clinical presentation and investigations including histopathological examination of a biopsy and negative bacterial cultures were consistent with the diagnosis of pustular psoriasis von Zumbusch type. Upon initial treatment with methylprednisolone, acitretin and antibiotics the extent of the disease declined. However, several attempts to reduce the dose of the oral corticosteroid were followed by immediate severe flares. Additional treatment with narrowband ultraviolet B (NB-UVB, 311-313 nm UVB) resulted in a rapid arrest of disease activity and allowed the corticosteroid to be tapered off. After 10 irradiations the patient was both off steroid and disease free. NB-UVB therapy was subsequently reduced to twice-weekly exposures and acitretin gradually diminished to a maintenance dose of 0.3 mg kg(-1) daily. We conclude that NB-UVB in conjunction with acitretin is a potent therapeutic regimen for the treatment of severe pustular psoriasis von Zumbusch type in childhood. 相似文献

Clinical measures of disease severity and outcome in psoriasis: a critical appraisal of their quality 总被引:10,自引:0,他引:10
In clinical trials, a wide range of outcome measures has been used to evaluate the severity of psoriasis and its response to treatment. Despite their widespread use, many measures have received little attention with regards to their reliability and validity. Selecting an appropriately developed measurement tool is therefore of critical importance. We conducted a literature survey to examine the status of clinical outcome measures used in psoriasis research. The measures most commonly used were individual sign scores, e.g. for erythema, plaque thickness or scaling, and pooled indices, e.g. the Psoriasis Area and Severity Index. None of these, however, systematically fulfilled all the requirements of a validated instrument for disease assessment. Ideally, a core set of reliable and validated outcome measures for use in all psoriasis clinical trials is needed. Objective instrumental methods should minimise observer variation, but unless a simple non-invasive method can be developed, the uptake of such technology will probably be limited by cost and lack of practicality. Moreover, the translation of instrumental readings into clinically relevant measures is always a major problem, and for none of the methods has there been a robust mapping of instrumental readings on to a clinically meaningful scale. Further research is needed to determine the most appropriate and sensitive parameters to use as surrogate measures for capturing the distress which psoriatic patients feel but which is not measured with sufficient sensitivity or precision with current quality of life or distress questionnaires. 相似文献

The remission period of psoriasis vulgaris following narrowband ultraviolet B (NB-UVB) light therapy with topical vitamin D(3) application was evaluated retrospectively to investigate the therapeutic efficacy. Fifty-two patients (60 cases) were treated with a 5-day/week protocol of NB-UVB light irradiation plus topical vitamin D ointment application for 1 month and followed up for at least 12 months. We considered re-exacerbation as the time when the patients needed treatment other than topical therapy. The remission period was defined as the duration from the end of treatment until re-exacerbation. Twenty-seven cases (56%) of psoriasis showed a remission period longer than 12 months. The patients with a past history of systemic therapy or phototherapy had a significantly shorter remission period than those without such a history. No statistically significant differences were observed in sex, age, period before treatment, Psoriasis Area and Severity Index score and total irradiation dose. A previous history of systemic therapy or phototherapy may mean that the disease is severe and sufficiently active to form multiple new lesions requiring these treatments. Our results suggest that the 5-day/week NB-UVB light protocol for 4 weeks is an effective and safe treatment for psoriasis vulgaris and can induce long-term remission. 相似文献

Background There is a perceived need for a better method for clinical assessment of the severity of psoriasis vulgaris. The most frequently used system is the Psoriasis Area and Severity Index (PASI), which has significant disadvantages, including the requirement for assessment of the percentage of skin affected, an inability to separate milder cases, and a lack of linearity. The Copenhagen Psoriasis Severity Index (CoPSI) is a novel approach which comprises assessment of three signs: erythema, plaque thickness and scaling, each on a four‐point scale (0, none; 1, mild; 2, moderate; 3, severe), at each of 10 sites: face, scalp, upper limbs (excluding hands and wrists), hands and wrists, chest and abdomen, back, buttocks and sacral area, genitalia, lower limbs (excluding feet and ankles), feet and ankles. Objectives To evaluate the inter‐rater and intrarater reliability of the CoPSI and to provide comparative data from the PASI and a Physician’s Global Assessment (PGA) used in recent clinical trials on psoriasis vulgaris. Methods On the day before the study, 14 dermatologists (raters) with an interest in psoriasis participated in a detailed training session and discussion (2·5 h) on use of the scales. On the study day, each rater evaluated 16 adults with chronic plaque psoriasis in the morning and again in the afternoon. Raters were randomly assigned to assess subjects using the scales in a specific sequence, either PGA, CoPSI, PASI or PGA, PASI, CoPSI. Each rater used one sequence in the morning and the other in the afternoon. The primary endpoint was the inter‐rater and intrarater reliability as determined by intraclass correlation coefficients (ICCs). Results All three scales demonstrated ‘substantial’ (a priori defined as ICC > 80%) intrarater reliability. The inter‐rater reliability for each of the CoPSI and PASI was also ‘substantial’ and for the PGA was ‘moderate’ (ICC 61%). The CoPSI was better at distinguishing between milder cases. Conclusions The CoPSI and the PASI both provided reproducible psoriasis severity assessments. In terms of both intrarater and inter‐rater reliability values, the CoPSI and the PASI are superior to the PGA. The CoPSI may overcome several of the problems associated with the PASI. In particular, the CoPSI avoids the need to estimate a percentage of skin involved, is able to separate milder cases where the PASI lacks sensitivity, and is also more linear and simpler. The CoPSI also incorporates more meaningful weighting of different anatomical areas. 相似文献

Disseminated superficial actinic porokeratosis (DSAP) is a subtype of porokeratosis, thought to be clonal disorder of keratinization. Chronic exposure to ultraviolet (UV) light might be an etiological cause of DSAP, of which frequent sites are sun-exposed areas. We report a case of DSAP that occurred on the trunk of a 79-year-old man with psoriasis treated with narrowband ultraviolet B (NB-UVB) for clearing and maintenance therapies. DSAP has been reported to associate with psoralen and ultraviolet A therapy and broadband UVB, but not NB-UVB. This may be the first case of DSAP after repeated exposure to NB-UVB. 相似文献

We examined the relation between adalimumab and infliximab plasma trough levels, anti‐adalimumab and anti‐infliximab antibody formation. We analyzed plasma from 32 adalimumab‐treated and 20 infliximab‐treated psoriasis patients for evaluating trough levels of each drug. The presence of anti‐adalimumab and anti‐infliximab antibodies was analyzed and the severity of psoriasis was evaluated. At week 28, 25 out of 32 and at week 48, 21 out of 30 adalimumab‐treated patients maintained as more than PASI 75. At week 28, 12 out of 20 and at week 48, nine out of 18 infliximab‐treated patients were evaluated as more than PASI 75. In patients treated with 40 mg adalimumab every other week, the mean trough level was 7.62 μg/mL (range, 0.05–10.6) at week 48. In patients treated with 80 mg adalimumab every other week, the mean trough level was 8.61 μg/mL (range, 0.08–13.5) at week 48. Mean trough level of infliximab‐treated cases (4.1–5.2 mg/kg; mean, 4.6) was 4.64 μg/mL (range, 0.03–16.9) at week 48. Anti‐adalimumab antibody was detected in five out of 32 cases and anti‐infliximab antibody was detected in six out of 20 cases, respectively, at weeks 24 and 48. The optimal cut‐off values of adalimumab and infliximab concentration for more than PASI 75 were more than 7.84 μg/mL and more than 0.92 μg/mL, respectively. The trough levels of adalimumab and infliximab in psoriasis patients were positively associated with clinical response and were significantly lower in cases having anti‐adalimumab or anti‐infliximab antibodies. 相似文献
