Immunoreactive plasma and synovial fluid concentrations of calcitoningene-related peptide II (CGRP II), substance P and vasoactiveintestinal peptide (VIP) were measured in patients with osteoarthritis,gout and rheumatoid arthritis. Significantly higher levels ofCGRP II and substance P and VIP-like immunoreactivity levelsin synovial fluid were found in gout as well as CGRP II, substanceP and VIP-like immunoreactivities in rheumatoid arthritis whencompared to those in osteoarthritis. Plasma CGRP II, substanceP and VIP-like immunoreactivity levels showed no significantdifferences among patients in the three different groups ofarthritis. Our results suggest that these neuropeptides releasedfrom peripheral nerve endings into the synovial cavity probablyplay a pathogenic role in human joint inflammation.

In a double-blind randomized study, 92 patients with culturally proven tinea corporis and/or tinea cruris were treated orally with either terbinafine (Lamisil) (125 mg b.i.d.) or griseofulvin (500 mg b.i.d.) for up to 6 weeks. The two groups of patients and distribution of the target lesions were similar, but the analysis of the clinical scores showed that the terbinafine group had slightly higher mean scores at baseline (P = 0.186). At the end of therapy the proportion of patients with negative microscopy and culture was 78% in the terbinafine group and 83% in the griseofulvin-treated group. At the assessment 8 weeks after the end of therapy the percentages of terbinafine- and griseofulvin-treated patients with negative mycology were 93 and 95%, respectively. There were three relapses after mycological cure in the griseofulvin group (8%) and two in the terbinafine group (4%). Griseofulvin-treated patients were treated for shorter periods than terbinafine-treated patients (i.e. 58% compared to 26% received only 2-4 weeks of therapy). In terms of overall effectiveness, there were no significant differences between the two treatments. Thirty-seven terbinafine patients (77%) compared to 36 griseofulvin patients (82%) had overall effective therapy. Eight terbinafine patients (16%) compared to 10 griseofulvin patients (20%) experienced at least one adverse event. Five patients in the terbinafine group and six in the griseofulvin group had to stop the treatment due to headaches or gastrointestinal disorders. One terbinafine patient had an elevation of liver function tests after 6 weeks of treatment.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Summary We report the first case of co-infection with herpes zoster and leishmania in the same lesion, on the face of a 29-year-old female, who was an intravenous drug user and who was HIV positive. The infection was initially resistant to acyclovir and itraconazole, and the patient died due to severe infection in the Mediterranean countries is increasing among the HIV-positive population because of the existence of human carriers. Paradoxically, most of these patients show mild forms of visceral leishmaniasis. 相似文献

ITRACONAZOLE VERSUS GRISEOFULVIN IN THE TREATMENT OF TINEA CAPITIS: A DOUBLE-BLIND RANDOMIZED STUDY IN CHILDREN 总被引:3,自引:0,他引:3
SARA LÓPEZ-GÓMEZ M.D. AMALIA DEL PALACIO M.D. Ph.D. JAN VAN CUTSEM M.D. Ph.D. MARIA SOLEDAD CUÉTARA M.D. Ph .D. LUIS IGLESIAS M.D. Ph .D. ANTONIO RODRIGUEZ-NORIEGA M.D. Ph .D. 《International journal of dermatology》1994,33(10):743-747
Background. Tinea capitis is a fungal infection in which topical therapy is often unsuccessful. Griseofulvin has been considered to be a first-line therapy. Other antifungal agents are the azole derivatives. Among these, itraconazole was compared with griseofulvin in children in a double-blind study. Patients and Methods. Thirty-four children and one adult with clinical signs and symptoms of tinea capitis and with positive culture and microscopy for dermatophytes have been included in a double-blind comparison between itraconazole, 100 mg daily, and ultramicronized griseofulvin, 500 mg daily. Both drugs were given for 6 consecutive weeks. The final evaluation was made 8 weeks after the end of treatment to allow the hairs to regrow. Seventeen itraconazole- and 15 griseofulvin-treated patients received the complete 6-week treatment course. Fifteen of these 17 itraconazole patients and 14 of the 15 griseofulvin patients had infections caused by Microsporum canis. Fifteen of 17 patients were cured by itraconazole (88%) and 15 of 17 patients by griseofulvin (88%). One of the patients who discontinued griseofulvin therapy after 4 weeks was clinically and mycologically cured. Two of the original 17 griseofulvin patients discontinued therapy because of vomiting. None of the itraconazole-treated children experienced side effects. Conclusions. Itraconazole is the first azole derivate that matches griseofulvin for the treatment of tinea capitis in children. The drug also appears to be better tolerated than griseofulvin. 相似文献

Contact allergens and sodium lauryl sulphate upregulate vascular endothelial growth factor in normal keratinocytes 总被引:1,自引:0,他引:1
In allergic and irritant contact dermatitis, keratinocytes are major target cells that can be activated to take part in local reactions by secreting soluble mediators. Among the growth factors produced by keratinocytes, vascular endothelial growth factor (VEGF) is a powerful inducer of permeability of endothelial cells, and is involved in inflammation. We determined whether different contact allergens, dinitrosulphobenzene (DNSB), para-phenylenediamine (pPD) and the metals nickel and chromium, as distinct from cobalt, which has been shown to mimic the effects of hypoxia, can modify the basal level of VEGF in normal human keratinocytes when tested at various, non-toxic concentrations. The effects of an irritant, sodium lauryl sulphate (SLS), and of hydrocortisone were also tested. Our results showed an intense dose-dependent upregulation of VEGF release by keratinocytes after treatments by metals, pPD and SLS. DNSB induced only a moderate increase of VEGF. Hydrocortisone reduced the basal level as well as the nickel-induced upregulation of VEGF. These findings suggest that contact allergens and irritants probably upregulate VEGF in keratinocytes by different mechanisms and may contribute directly to the microvascular hyperpermeability which characterizes both contact and irritant dermatitis. 相似文献
