Abnormalities in plasma composition of essential fatty acids (EFAs) may be associated with the etiology of pruritus and other skin problems in patients undergoing hemodialysis. To study whether an oral supplementation with omega-6 (n-6) EFAs would restore deranged plasma EFAs and ameliorate skin symptoms, 9 and 7 dialysis patients were randomly assigned to receive either gamma-linolenic acid (GLA)-rich evening primrose oil (EPO) or linoleic acid (LA) (2 g/day each) for 6 weeks. Plasma concentrations of EFA were analyzed by gas chromatography and uremic skin symptoms were assessed for dryness, pruritus and erythema by questionnaire and visual inspection in a double-blind manner. The patients given EPO exhibited a significant (p < 0.05) increase in plasma dihomo-gamma-linolenic acid (a precursor of anti-inflammatory prostaglandin E1) with no concomitant change in plasma arachidonic acid (a precursor of pro-inflammatory prostaglandin E2 and leukotriene B4). In contrast, those given LA exhibited a significant (p < 0.05) increase in LA but not in any other n-6 EFAs, whereas they exhibited a significant (p < 0.05) decrease in plasma docosahexaenoic acid. The patients given EPO showed a significant (p < 0.05) improvement in the skin scores for the three different uremic skin symptoms over the baseline values and a trend toward a greater improvement (0.05 < p < 0.1) in pruritus scores than those given LA. Results indicate that GLA-rich EPO would be a more favorable supplemental source than LA in terms of shifting eicosanoid metabolism toward a less inflammation status through modifying plasma concentrations of their precursor n-6 EFAs. Further studies are required to confirm the efficacy and safety of EPO therapy for the treatment of uremic pruritus.

Adverse effects of amlodipine besylate, a widely used antihypertensive medication, include peripheral edema, flushing, headache, pruritus, and rash. An adverse renal effect attributable to the medication has hitherto not been reported in the literature. We herein report a case of amlodipine besylate induced acute interstitial nephritis.

The aim of this study was to investigate the efficacy and tolerability of intranasally applied dimetindene (CAS 3614-69-5) 0.1% spray in children suffering from seasonal allergic rhinitis. A total of 100 children under 14 years with acute seasonal allergic rhinitis participated in this randomised, single-blind, reference-controlled, multi-center, parallel group study with two treatment groups. The study took place between 2nd April and 16th September 1996 during the pollen season. Patients were examined at enrollment (day 1), day 8 and day 15. Patients kept diary throughout the 2-week treatment phase. Patients were randomised to receive either dimetindene 0.1% (Fenistil Nasal Spray) or a levocabastine (CAS 79516-68-0) 0.05% solution as reference medication. Both medications were supplied in similar outer packages. A single-blind approach was chosen, because the reference medication levocabastine requires two spray puffs per nostril as a single dose, whereas for dimetindene maleate solution a single spray puff per nostril is sufficient. Dimetindene 0.1% was applied with 1 spray puff (= 0.14 mg dimetindene) in each nostril and levocabastine with 2 spray puff (= 0.10 mg levocabastine) in each nostril every day in the morning before leaving the house and in the evening before going to bed. Additional administration of the spray was allowed up to 4 times a day if needed. Efficacy was assessed as change in severity of characteristic symptoms associated with pollen rhinitis: nasal rhinorrhea, nasal itching, nasal sneezing and nasal congestion. In addition, changes in ocular symptoms, lacrimation, ocular itching and red eyes, global physician's assessment of efficacy at the end of treatment were assessed. The primary criterion change of total nasal symptom severity score between day 1 and day 3 resulted in a statistically equivalent and therapeutically relevant symptom reduction for the two treatments. All secondary criteria showed a similar reduction in symptoms, thus underlining the consistency of the findings. Both nasal sprays were well tolerated. It is concluded from these results that dimetindene 0.1% nasal spray solution is a safe and efficient treatment option for children under 14 years suffering from seasonal allergic rhinitis.

Skin involvement in chronic renal failure is characterised by a multitude of different aspects. Apart from the typical yellow-brown discolouration of the skin, most often patients complain of pruritus and xerosis cutis. A marked actinic elastosis is noticed. Dialysis treatment alters and partly aggravates these pre-existing skin conditions. When chronic renal failure leads to a kidney transplantation, some of the reversible skin pathology, e.g. pruritus, xeroderma, tends to ameliorate, but a high tendency to develop malignancies becomes prominent.
