[Five cases of erythema infectiosum in adults].

The similarities between clinical features of erythema infectiosum and collagen disease or other viral infections prompted us to investigate clinical manifestations and laboratory data of parvovirus B19 (B19) infection in adults. We diagnosed all five patients as acute B19 infection by antibody assays. The age of patients ranged from 18 to 39 years old (mean 29), and all patients were female. All five patients showed high fever, arthralgia and edema of the extremities. Four of the five patients showed skin rash of the extremities or cheeks. Two patients were diagnosed as erythema infectiosum by family physicians before coming to us. The three remaining patients were suspected to be systemic lupus erythematosus, adult Still disease or rubella indivisually and referred to our hospital. A-27-old female (case 5) visited our hospital because of polyarthralgia and butterfly rash on her face. A test for antinuclear antibodies (ANA) was positive at a dilution of 1:320. Rheumatoid factor (RF) was also detected by latex fixation test. Her AST was 51 IU/L, ALT 68 IU/L and LDH 568 IU/L. Her symptoms persisted for 3 weeks and hepatic dysfunction recovered within 3 weeks. Five months later. ANA was negative at the dilution of less than 1:40. We suggest that the similarities between some symptoms of B19 infection and clinical and serological manifestation of collagen diseases merit closer attention.

United States standard diphtheria toxin for the Schick text and the erythema potency assay for the Schick text dose.

A diphtheria toxin shown to have high toxicity and avidity and to combine with antitoxin in multiple proportions was selected for the U.S. standard diphtheria toxin for the Schick test and freeze-dried. Assayed values per vial were 1.09 L(f), 1.09 L(r), 1,090 Schick test doses (STD), 33 LD(80), 38 LD(50), and 43,000 minimum skin reactive doses. One STD (L(r)/1000) is slightly more toxic than one unit of the international standard (L(f)/1,000). Experiments showed that the potency assay of Schick test toxin by guinea pig erythema toxicity, determined relative to the toxicity of the standard, was highly reproducible and significantly more reproducible than the lethal (minimum lethal dose) test and that the STD, defined as one L(r)/1000, was equivalent to approximately 1/50 minimum lethal dose. The erythema potency assay was prescribed in the U.S. standards for Schick test toxin effective in 1969.

Serodiagnosis of erythema migrans and acrodermatitis chronica atrophicans by the Borrelia burgdorferi flagellum enzyme-linked immunosorbent assay.

The diagnostic performance of an enzyme-linked immunosorbent assay (ELISA) using purified Borrelia burgdorferi flagella as test antigen was compared with that of a B. burgdorferi sonic extract ELISA. We tested sera from 200 healthy controls, 107 patients with erythema migrans (EM), 50 patients with acrodermatitis chronica atrophicans (ACA), and 98 patients with various dermatological disorders without clinical evidence of active Lyme borreliosis. The flagellum ELISA was significantly more sensitive than the sonic extract ELISA. With sera from patients with EM, the diagnostic sensitivity for immunoglobulin G (IgG) antibody detection increased from 11.2 to 35.5% (P less than 0.001) and for IgM antibody detection it increased from 16.6 to 44.8% (P less than 0.001). In the flagellum ELISA, the number of positive tests increased significantly (P less than 0.005) when the duration of EM exceeded 1 month, but still only about 50% of patients with longstanding (1 to 12 months) untreated EM were IgG seropositive. Concomitant general symptoms did not affect the antibody level, whereas patients with multiple erythema were more frequently seropositive. All sera from patients with EM which were positive in the sonic extract ELISA were also positive in the flagellum ELISA. Not only did the overall number of positive tests increase, but the flagellum ELISA yielded a significantly better quantitative discrimination between seropositive patients and controls (P less than 0.002). IgG antibodies to the B. burgdorferi flagellum were found in all sera from patients with ACA, indicating persistence of an antiflagellum immune response in late stages of Lyme borreliosis. IgM reactivity in sera from patients with ACA was shown to be unspecific and the result IgM rheumatoid factor. A rheumatoid factor was detected in sera from 32% of patients with ACA, compared with 7.5% of patients with EM. The improved diagnostic performance, the ease of standardization of the flagellum antigen, and the lack of strain variation make the B. burgdorferi flagellum a needed reference antigen for growing routine serology in Lyme borreliosis.

Ovalbumin blocking improves sensitivity and specificity of immunoglobulin M immunoblotting for serodiagnosis of patients with erythema migrans.

To improve the serodiagnosis of erythema migrans, we evaluated how sensitivity and specificity of immunoblotting are influenced by antigen concentration and blocking conditions. We found that an antigen concentration of 0.5 micrograms per lane in concert with ovalbumin blocking of the nitrocellulose provided the best results. In this case, 81% of the erythema migrans had positive immunoglobulin M tests, whereas only 33% were positive in a flagellum enzyme-linked immunosorbent assay (ELISA) and 28% were positive in a sonicate ELISA.

Quantitative detection of Borrelia burgdorferi in 2-millimeter skin samples of erythema migrans lesions: correlation of results with clinical and laboratory findings.

Variability of disease manifestations has been noted in patients with Lyme disease. A contributing factor to this variation may be the number of spirochetes present in infected patients. We evaluated clinical and laboratory findings for patients with erythema migrans with regard to the number of Borrelia burgdorferi organisms detected by quantitative PCR (qPCR) in 2-mm skin biopsy specimens. B. burgdorferi was detected in 80% (40 of 50) of the specimens tested; the mean number of spirochetes in these specimens ranged over 3 orders of magnitude (10 to 11,000 spirochetes per 2-mm biopsy specimen). Larger numbers of spirochetes were significantly associated with a shorter duration of the erythema migrans skin lesion (P = 0.020), smaller skin lesions (P = 0.020), and infection with a specific genotype of B. burgdorferi (P = 0.008) but not with the number or severity of symptoms. Skin culture positivity was significantly associated with skin lesions containing larger numbers of spirochetes (P = 0.019).

Erythema nodosum due to Pasteurella pseudotuberculosis.

Two children developed erythema nodosum due to Pasteurella pseudotuberculosis. Neither case showed typical signs of P. pseudotuberculosis infection, but this cause was shown by positive agglutination tests. It is suggested that this organism is a more common cause of erythema nodosum than is at present recognized.

Erythema nodosum--diagnostic difficulties in the accident and emergency department.

Five patients presenting with erythema nodosum to an accident and emergency department are described. Initially they were misdiagnosed as cellulitis, infected insect bites, and minor trauma. Suspicious skin lesions or joint manifestations occurring either alone or especially if in combination should alert the wary clinician to the possibility of erythema nodosum and follow up in a few days may help to confirm the diagnosis.

Erythema nodosum progressing to pyoderma gangrenosum as a complication of Crohn's disease.

Erythema nodosum occurs more frequently than pyoderma gangrenosum in Crohn's disease. We report the occurrence of both lesions in a woman with Crohn's disease and the transformation of one to the other. Pyoderma gangrenosum has been described at the site of previous trauma in Crohn's disease and at the site of other skin conditions in other circumstances, but, to the best of our knowledge, actual progression from erythema nodosum to pyoderma gangrenosum has been reported on only one previous occasion in Crohn's disease.

Palmar-plantar erythema associated with combination chemotherapy.

We report three cases of a distinctive palmar-plantar erythema associated with the treatment of non-Hodgkin's lymphoma and acute myeloid leukaemia. The rash is characterized by a painful, sharply demarcated, intense erythema of the palms and/or soles followed by bulla formation, desquamation and healing. The eruption is self limiting in nature and did not adversely affect prognosis. Treatment need be neither altered nor stopped; only symptomatic measures are required.

Erythema multiforme to amoxicillin with concurrent infection by Epstein-Barr virus.

BACKGROUND: The incidence of rashes following the intake of aminopenicillins during an acute episode of infectious mononucleosis is high, but severe cutaneous reactions as erythema multiforme or Stevens-Johnson syndrome are rare manifestations in childhood. MATERIAL AND METHODS: We report the case of a 7 year old girl that developed a generalized purpuric rash with target shaped areas, 9 days after starting treatment with amoxicillin-clavulanic acid. Laboratory investigation revealed a significant increase of Epstein Barr virus (EBV) specific IgM antibody. After skin biopse she was diagnosed as erythema multiforme syndrome. Prick, intradermal and patch tests were performed with penicilloylpolylysine, minor determinant mixture, benzylpenicillin, ampicillin, amoxicillin, cefazoline and cefotaxime, the 24 hours reading was positive for aminopenicillins. Patch tests were also positive only for aminopenicillins, other betalactams were negative. CONCLUSIONS: The interaction between an infectious agent (EBV) and amoxicillin could precipitate the severe skin reaction. Patch test and delayed intradermal reading with amoxicilllin were an useful tool for the diagnosis of the etiological agent in this reaction. The negative response to other beta-lactams, suggests that the aminobenzyl group of the side chain of amoxicillin plays a predominant role in this reaction.

Erythema multiforme-like eruption due to carbamates and thiuram.

Report of a case of erythema multiforme-like eruption due to the use of rubber gloves. After several complementary studies, including epicutaneous and skin prick tests, we concluded that the eruption was secondary to sensitization to carbamates and thiuram. The main differential diagnosis in this case was allergic contact dermatitis to latex in natural rubber gloves. This entity is less frequent than might be expected, because it is usually due to intermediate chemical compounds used in rubber manufacturing, such as vulcanization accelerators; among of these latter compounds are thiurams and carbamates. Erythema multiforme-like eruption is a rare manifestation of contact dermatitis. Several cases have been reported, most of which have been due to contact with plants, metals or topical non-steroidal anti-inflammatory drugs. Its mechanism is still unclear, but it seems to be a type IV hypersensitivity reaction.

Erythema multiforme associated with cytomegalovirus infection in nonimmunosuppressed patients.

BACKGROUND: It is widely known that cytomegalovirus (CMV) primarily brings about subclinical and asymptomatic infection in the early stages of life and can cause various dermatological and systemic disorders under immunosuppressed conditions. Nonimmunosuppressed individuals very rarely present with cutaneous CMV involvement. OBJECTIVE: In the present study, we described the clinical characteristics of 5 nonimmunosuppressed adult patients with positive IgM antibody to CMV. METHODS: The systemic symptoms and dermatological features of these 5 patients were described. Laboratory examinations including blood cell counts, liver and renal functions were performed. IgG and IgM antibodies to CMV were also examined at the first consultation and 2-3 months after the skin eruption. Polymerase chain reaction for CMV DNA was performed in the skin samples of the patients. RESULTS: All 5 patients had fever and complained of a sore throat. Multiple exudative erythema and target lesions with itching were observed mainly on the extremities. These symptoms and eruptions disappeared within 1 week after the onset and IgM antibody titers significantly decreased after 2-3 months. IgG antibody to CMV was already positive in 3 cases but was negative in 2 cases at the initial consultation. CONCLUSION: We propose that CMV infection may cause erythema multiforme by primary, recurrent infections or reactivation of CMV even in nonimmunosuppressed adults.

Periorbital oedema and erythema as a manifestation of discoid lupus erythematosus.

Periorbital oedema and erythema are a rare cutaneous manifestation of discoid erythematosus (DLE) which is well known to ophthalmologists but less to dermatologists. We report the case of a 74-year-old female patient with periorbital oedema and erythema. Since swelling of the eyelid is common in the dermatological practice, dermatologists should be aware of the differential diagnosis and its occurrence in patients with DLE.

Effects of oral bexarotene (targretin) on the minimal erythema dose for broadspectrum UVB light.

Photo(chemo)therapy and oral retinoid therapy for psoriasis or cutaneous T-cell lymphoma are frequently combined to obtain an enhanced therapeutic effect with lower safety risks. Bexarotene, a new RXR-selective retinoid (rexinoid), has been developed for the treatment of cutaneous T-cell lymphoma and has recently been investigated in the treatment of psoriasis. In the present study the UV-modulating properties of bexarotene were evaluated by assessment of the minimal erythema dose (MED) for UVB light. In 11 patients participating in a phase II study of oral bexarotene 0.5 mg/kg/day (7 patients) or 3.0 mg/kg/day (4 patients) for plaque-type psoriasis, MED tests were performed on uninvolved psoriatic skin on the lower back of the subjects before and after 12-week treatment. Clinical scores of erythema and determination of the MED 24 h after irradiation did not show statistically significant changes between the exposed areas before and after bexarotene treatment or between the two doses tested. No photosensitizing reactions were observed. This study demonstrates that a single exposure to UVB irradiation is well tolerated in patients treated with bexarotene 0.5-3.0 mg/kg/day and suggests that it is not necessary to take precautions with respect to short-term effects of sun exposure during bexarotene treatment. Further study of bexarotene photo(chemo)therapy in cutaneous T-cell lymphoma and psoriasis is warranted.

Predominant telangiectatic erythema in linear atrophoderma of Moulin: novel variant or separate entity?

Linear atrophoderma of Moulin is a distinctive disease originally described in 1992 and characterized by acquired, mildly atrophic, non-sclerotic, slightly hyperpigmented lesions following the lines of Blaschko. Here, we describe a 15-year-old girl with a 13-year history and a 29-year-old male with a 6-year history of prominent linear telangiectatic erythema and mild atrophoderma following the lines of Blaschko that involved the right leg and hip, and both legs, the trunk and both arms, respectively. As pronounced telangiectatic erythema within lesions of atrophoderma of Moulin has not hitherto been described, we propose that the disease in our patients represents a novel variant of linear atrophoderma of Moulin. Due to considerable overlap, we do not favour the notion that our cases constitute an entity entirely separate from linear atrophoderma of Moulin.

Erythema multiforme-like drug eruption with oral involvement after intake of leflunomide.

Leflunomide is an antirheumatic agent of the type of a 'disease-modifying antirheumatic drug'. In rare cases, severe skin reactions up to the extreme expression of toxic epidermal necrolysis have been observed. A female patient with rheumatoid arthritis had been treated with systemic steroids and methotrexate for 2 years. Five weeks prior to admission to our hospital methotrexate was replaced by leflunomide. Three weeks after initiation of leflunomide therapy a progressive generalized erythema with blistering formation occurred accompanied by increase of body temperature, chills and erosive lesions on the lips and oral mucosa. The palmar and plantar surfaces revealed edema, erythema and pulpitis with epidermolysis. On histologic examination necrotic keratinocytes and epidermal spongiosis were observed. After administration of high-dose prednisolone and topical treatment the patient recovered within 14 days. This is one of the few cases of severe drug reaction after intake of leflunomide. Therefore, the indication of this relatively new drug should be considered carefully.

Prevalence of Erythema migrans Borreliosis in blood donors.

European Erythema migrans Borreliosis and North American Lyme disease are closely related to syphilis. This implicates a potential risk of infection for blood recipients. Eighty-six of 3,157 blood donors tested showed IgG-antibodies against Borrelia Burgdorferi. From among 47 persons of this group who could be examined, clinical signs of diseased skin, joints or nervous system, not diagnosed before, were found or could be suspected in 13 cases. Since intrauterine transmission of Borrelia infection has been described, the inevitable question of whether this disease can also be transmitted as a result of blood transfusion becomes a major concern. As the pathogen can persist even in the presence of serum antibodies, it seems advisable to examine blood donors serologically, whenever Erythema migrans Borreliosis is suspected. Though further research is required to document a transfusion-transmitted Borrelia infection, infected persons should be treated to avoid serious or late manifestations.
