Does chloroquine therapy of porphyria cutanea tarda influence liver pathology?

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 11 2009
U Wollina MD
Background, Porphyria cutanea tarda (PCT) is regularly associated with changes in liver tissue. On the other hand, systematic investigations are lacking on whether there is a correlation between the severity of liver damage and chloroquine treatment. Patients and methods, During a 20-year period, liver biopsies were obtained in 89 patients with PCT confirmed by biochemical analysis of urine and feces and low-dose chloroquine therapy. Seventeen patients with alcohol-induced liver disease were excluded. In 8 of 63 patients, only a single biopsy was available. Classification of liver damage was performed according to the Riedel score. Electron microscopy was available from 24 patients. In a second group of patients, the HFE status was investigated and Berlin blue stains of liver biopsies were performed. Results, There was no correlation between the duration of cutaneous symptoms and liver pathology. After 12 months chloroquine treatment, 45 patients (81%) disclosed an improvement of liver pathology, nine (16%) had no change, and a worsening was observed in one patient (3%). All patients achieved a complete clinical and biochemical remission. In 13 of 16 patients with a relapse, there was again a deterioration of liver damage. Patients with HFE mutations had a significant higher risk (P < 0.05) for hepatic siderosis. Conclusions, The severity of liver damage was not correlated with the disease duration. Chloroquine treatment resulted in PCT remission (clinical and biochemical) and in 81% to an improvement of liver morphology. [source]


Cutaneous manifestations of Wegener's granulomatosis: a clinicopathologic study of 17 patients and correlation to antineutrophil cytoplasmic antibody status

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 10 2007

Background:, Wegener's granulomatosis (WG), a systemic vasculitis, can be associated with cutaneous signs and symptoms before, during or after the diagnosis of systemic disease. Methods:, We reviewed clinical and histologic features of cutaneous lesions from 17 patients with WG. The temporal relationship between development of cutaneous symptoms and onset of systemic disease was determined, and antineutrophil cytoplasmic antibody (ANCA) status of the patients was also established. Results:, In six patients, systemic and cutaneous disease developed concurrently. In eight patients, cutaneous disease developed after patients received the diagnosis of systemic disease. In three patients, cutaneous disease preceded systemic disease. Cytoplasmic ANCA or proteinase-3-ANCA [c-ANCA/proteinase 3 (PR3)-ANCA] serologic test results were negative for one patient when cutaneous disease developed, and one patient had c-ANCA/PR3-ANCA seroconversion a year before systemic disease developed. Histopathologic features of cutaneous WG were not limited to leukocytoclastic vasculitis; they also included acneiform perifollicular and dermal granulomatous inflammation and palisaded neutrophilic and granulomatous inflammation. Conclusions:, Patients with WG can present initially with cutaneous symptoms. Histopathologic patterns vary, but leukocytoclastic vasculitis is most commonly noted. Patients with WG and skin lesions are likely to have positive c-ANCA/PR3-ANCA serologic test results. [source]


The use of topical calcineurin inhibitors in lupus erythematosus: an overview

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 1 2008
U Wollina
Abstract Lupus erythematosus (LE) shows a broad range of cutaneous symptoms, including acute, subacute and chronic lesions. The gold standard of established topical treatment consists of medium- to high-potency corticosteroids. Because face and neck are often involved, adverse effects of prolonged corticosteroid use are not uncommon. There is a need of steroid-free topical treatment in LE. With the development of topical calcineurin inhibitors, tacrolimus and pimecrolimus, there is an alternative available. The present study reviews the literature data on topical tacrolimus and pimecrolimus for malar rash, subacute lesions and discoid chronic lesions among others. The present data argue for an efficacy of these compounds in acute and subacute cutaneous LE manifestations with a rapid response and only minor side-effects when used as an adjunct to systemic treatment. In chronic discoid LE, hypertrophic plaques do not well respond because of limited penetration. The primary target seems to be the decrease or blocking of cytokine production by activated T lymphocytes. [source]


Anaphylaxis to Patent Blue V. I. Clinical aspects

ALLERGY, Issue 1 2010
A. S. Hunting
Abstract Background:, The dye Patent Blue V (PBV) is increasingly used for staging procedures in operable breast cancer, but is reported to cause adverse reactions. The aim of this study was to present the clinical features and the results of follow-up examinations in patients with such reactions. Methods:, We studied nine patients with hypersensitivity reactions to PBV between 1999 and 2006 who were identified through the Norwegian network for reporting and investigating allergic reactions during anesthesia. Results:, We observed incidences of 0.5% (7/1418) for all kinds of PBV reactions and 0.4% (5/1418) for anaphylaxis. Typical clinical features included: (i) cardiovascular and/or cutaneous symptoms, (ii) a delay in symptoms, compared to the time of dye injection, (iii) poor response to ephedrine and intravenous fluid, and (iv) need for adrenaline administration, sometimes prolonged, for circulatory stabilization. Cutaneous manifestations were noted in five of the seven patients with anaphylaxis and two additional patients without circulatory instability. During anaphylactic reactions, serum tryptase was increased in six patients and normal in one. Serum tryptase was normal in one patient with skin symptoms only. Skin prick tests to PBV were positive in all eight patients tested, including the two with skin manifestations only. Conclusion:, The clinical features and the results of follow-up studies strongly suggest that these reactions are IgE mediated. [source]


Changes in serum lactate dehydrogenase activity in children with atopic dermatitis

PEDIATRICS INTERNATIONAL, Issue 2 2010
Yasuyuki Morishima
Abstract Background:, In recent years an increase has been seen in the number of patients with severe atopic dermatitis (AD) accompanied with generalized typical eruptions. Some markers indicating the severity of the disease and symptom changes are very useful, and therefore the purpose of the present study was to investigate serum lactate dehydrogenase (LDH) as such a marker. Methods:, A total of 58 children with AD were enrolled. The severity of the disease was graded on the basis of the extent of eruptions and the severity of atopic symptoms. The fraction of serum LDH, number of eosinocytes in the peripheral blood, and serum IgE levels were also determined. Results and Conclusion:, There was a close correlation between the severity of cutaneous symptoms and serum LDH activity, and between severity and eosinocyte count, but no relationship was seen between serum IgE levels and severity of the disease. The aforementioned factors were determined in a time-related way. As the patients' condition improved, serum LDH activity tended to decline, but there were no consistent changes in eosinocyte count in the peripheral blood or serum IgE level. On LDH isozyme the levels of LDH4 and LDH5 were high. Tissue showed high LDH activity, especially in epidermides. These results suggest that serum LDH activity is a useful marker. [source]

ABSTRACT We report a patient with Darier's disease successfully treated with photodynamic therapy. She had previously been recalcitrant to treatment with emollients, topical corticosteroids and retinoids. Photodynamic therapy was trialled with significant clinical improvement in her cutaneous symptoms and signs that was maintained for over 27 months. [source]


Allergic contact dermatitis following exposure to essential oils

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2002
Narelle Bleasel
SUMMARY Allergic contact dermatitis from the topical use of essential oils is not widely recognized as an occupational hazard. Four cases of allergic contact dermatitis to essential oils occurring in three aromatherapists and one chemist with a particular interest in aromatherapy are described. All presented with predominantly hand dermatitis and demonstrated sensitization to multiple essential oils. One patient developed a recurrence of cutaneous symptoms following ingestion of lemongrass tea. Workers within this industry should be aware of the sensitization potential of these products and the risk of limiting their ability to continue employment. [source]


Frequent association between MEN 2A and cutaneous lichen amyloidosis

CLINICAL ENDOCRINOLOGY, Issue 2 2003
Uberta Verga
Summary objective Multiple endocrine neoplasia type 2A (MEN 2A) and familial medullary thyroid carcinoma (FMTC) are genetic diseases due to activating mutations of the RET proto-oncogene. Affected patients develop medullary thyroid carcinoma (100%), in an isolated form (FMTC) or in association with phaeochromocytoma (30,50%), and primary hyperparathyroidism (10,20%) (MEN 2A). The presence of cutaneous lichen amyloidosis (CLA) has been anecdotally described in few families harbouring RET proto-oncogene mutation in codon 634. The aim of the study was to evaluate the incidence of CLA in MEN 2A/FMTC families. patients and design Ten MEN 2A/FMTC families were studied and RET gene mutations identified in all. Complete dermatological assessment was carried out in each family member. Skin biopsy for histological studies was performed in patients with CLA. results Among 10 MEN 2A/FMTC families, the presence of CLA was found only in patients belonging to the three families with MEN 2A and RET mutation in codon 634. Nine of 25 patients (36%) with codon 634 mutation presented CLA, though two of them did not show CLA skin lesions but the typical neurological pruritus in the upper back. In all patients, neurological pruritus was present since infancy as a precocious marker of the disorder. The dermatological study of patients with CLA skin lesions added further evidence that pruritus has a pivotal role in the development of CLA, the amyloid deposition being the consequence of repeated scratching. Light microscopy revealed orthokeratotic hyperkeratosis, with elongation of the rete ridges, rare intramalpighian apoptic keratinocytes and deposits of amorphous material in the superficial dermis. Examination under ultraviolet light showed thioflavin T-positive staining, confirming the presence of amyloid in the papillary dermis. The use of Capsaicin at the dilution of 0·025% had a mild efficacy on the cutaneous symptoms. conclusions Among the members of the three families with MEN 2A and RET 634 mutation, the incidence of CLA was 36%, a figure similar to that reported in the literature for phaeochromocytoma (30,50%) and even higher than that for hyperparathyroidism (10,20%). The present data confirm that CLA is linked to codon 634 RET mutations and is a precocious marker of the disorder. [source]


Neonatal management of symptomatic transplacental cryoglobulinaemia

ACTA PAEDIATRICA, Issue 4 2004
V Laugel
This study reports the first case of symptomatic placental transfer of cryoglobulins and discusses the potential pathogenic processes and the basic guidelines for neonatal management. A 32-y-old woman was affected by essential type I cryoglobulinaemia and displayed the cold-triggered cutaneous symptoms of the disease due to a monoclonal immunoglobulin G (IgG) cryoglobulin. She gave birth to healthy dizygotic twins who were placed in incubators immediately after birth and did not show any cutaneous or visceral lesion in the first 2 d. Cyanotic macules appeared on the hand and foot of one of the newborns when they were removed from the incubators. The same monoclonal IgG-, cryoglobulin was identified in the two newborns'cord blood and in the mother's serum. The skin lesions disappeared within 1 wk as both twins were transiently replaced in incubators. No recurrence of skin lesions was observed even at room temperature and, 6 mo later, both twins were healthy and their clinical examination was normal. Conclusion: To the authors'knowledge, this is the first report of placental transfer of cryoglobulins and the first description of any neonatal effect. Neonates born to mothers suffering from IgG cryoglobulinaemia should be protected against cold to avoid precipitation of the pathogenic cryoglobulins, until spontaneous resolution. [source]
