Acrodermatitis continua of Hallopeau: response to combined treatment with acitretin and calcipotriol ointment

Treatment of acrodermatitis continua of Hallopeau (ACH) is difficult and often disappointing. We describe a patient with an extensive ACH of all finger- and toetips, who was treated with acitretin combined with calcipotriol. A within-subject left/right comparison was carried out between calcipotriol ointment (50 micrograms/g) and the ointment base to investigate the additional value of calcipotriol above the ointment base. The side treated with calcipotriol as adjunct therapy showed an impressive improvement, well beyond the degree of improvement at the side treated with the ointment base only.

Success and failure in the treatment of acrodermatitis chronica atrophicans

To determine the most effective treatment for acrodermatitis chronica atrophicans, several clinical trials were undertaken in recent years to evaluate whether a 2-week course of ceftriaxone would be superior to oral antibiotics. Of the 46 patients suffering from acrodermatitis chronica atrophicans, 14 were treated with ceftriaxone 2g for 15 days. The remaining patients received either oral penicillin V 1.5 million IU t.i.d. or doxycycline 100 mg b.i.d. for 20 to 30 days. Patients were followed up for at least 1 year. Of the 14 ceftriaxone-treated patients four showed incomplete regression of the inflammatory skin changes after 6 to 12 months. Two out of five patients who were monitored for Borrelia burgdorferi DNA excretion were still positive after 12 months as compared to none of six patients who were treated orally for 20-30 days. Six out of 11 patients treated orally for only 20 days needed retreatment after 6 months because of continuing skin manifestations, neuropathy or arthralgia. A 30-day duration of treatment with oral antibiotics and not the chosen antibiotic is crucial for curing acrodermatitis chronica atrophicans. The duration of treatment with ceftriaxone needed for eradication of Borrelia in acrodermatitis chronica atrophicans has yet to be determined in future studies.

[Gianotti-Crosti syndrome in Epstein-Barr virus infection]

Gianotti-Crosti syndrome, a relatively rare, distinctive eruption occurring after hepatitis B infection, is characterized by a lichenoid papular exanthema, usually localized on the face, limbs, and buttocks. Hepatitis B antigenaemia is associated with Gianotti-Crosti syndrome only in some cases. Recent reports indicate that a variety of infectious agents are associated with Gianotti-Crosti syndrome. This is a report of 2 1/2-year-old girl with Gianotti-Crosti syndrome and concurrent primary Epstein-Barr virus infection without evidence of hepatitis B infection.

Lymphoproliferative responses to Borrelia burgdorferi in patients with erythema migrans, acrodermatitis chronica atrophicans, lymphadenosis benigna cutis, and morphea

BACKGROUND AND DESIGN

Specific humoral and cell-mediated immune responses play an important role in the pathogenesis of Lyme borreliosis. Several previous studies demonstrated that a specific cellular immune response to Borrelia burgdorferi can occur independently of a diagnostic humoral response. Little is known about T-cell reactivities against B burgdorferi in early and late cutaneous manifestations of Lyme borreliosis. We studied the lymphoproliferative response of peripheral blood mononuclear cells to B burgdorferi antigen from 99 patients (25 with erythema migrans, 16 with acrodermatitis chronica atrophicans, 13 with lymphadenosis benigna cutis, and 45 with localized scleroderma) and 21 control subjects. The results are expressed as a stimulation index (SI) (mean count per minute of triplicate cultures with stimulant divided by mean count per minute without stimulant). The serum samples from all patients and control subjects were tested for antibodies to B burgdorferi by indirect immunofluorescence assay.

RESULTS

The 21 healthy seronegative controls had an SI of 3.3 +/- 2.0 (mean +/- SD). Compared with that of control subjects, the SIs were significantly elevated in patients with erythema migrans (9.8 +/- 9.1), acrodermatitis chronica atrophicans (11.8 +/- 8.2), and lymphadenosis benigna cutis (7.2 +/- 6.2). The 45 patients with localized scleroderma had elevated proliferative responses, with an SI of 6.5 +/- 7.3, but these responses did not significantly differ from those of controls. Elevated titers of antibodies to B burgdorferi were present in six (24%) of 25 patients with erythema migrans, five (38%) of 13 patients with lymphadenosis benigna cutis, and 13 (29%) of 45 patients with localized scleroderma. All 16 patients with acrodermatitis chronica atrophicans had markedly elevated antibody titers.

CONCLUSIONS

Our findings show that a significant lymphoproliferative response to B burgdorferi occurs in the majority of patients with cutaneous manifestations of Lyme borreliosis. The lymphocyte proliferation assay may be of diagnostic value in patients in whom Lyme borreliosis is strongly clinically suspected and who have nondiagnostic levels of antibodies against B burgdorferi.

Changes in Borrelia burgdorferi-specific serum IgG antibody levels in patients treated for acrodermatitis chronica atrophicans

The kinetics of Borrelia burgdorferi-specific serum IgG antibody values in 74 patients treated for acrodermatitis chronica atrophicans was analysed by means of enzyme-linked immunosorbent assay. At the last clinical control, there had been no clinical signs of active infection. The serological follow-up time ranged from 12 months to 5 1/2 years (median 2 years and 1 month). In 68 (92%) of the 74 patients, a significant decrease of the specific antibody values was found within 3 years after the initiation of therapy. In 53 (72%) of the patients, this decrease was found within 15 months. Most of the patients remained seropositive during the follow-up period. The results show that a significant decline of the levels of serum IgG antibodies to Borrelia burgdorferi can be expected in the majority of patients who do not exhibit clinical evidence of persistent infection after antibiotic treatment of acrodermatitis chronica atrophicans.

Acrodermatitis enteropathica, zinc metabolism, copper status, and immune function

OBJECTIVE

To study zinc metabolism, copper status, and immune function in a patient with acrodermatitis enteropathica.

RESEARCH DESIGN

Case report.

PATIENT

A 16-year-old boy with acrodermatitis enteropathica.

INTERVENTION

Change of zinc supplementation dosage from 1000 to 525 mumol/d.

MEASUREMENTS AND RESULTS

Zinc metabolism was studied with an oral dose of zinc chloride Zn 65 and whole-body counting at both zinc dosages. Zinc, copper status, and immune indexes were also measured at both dosages. The higher dosage of zinc supplementation was found to induce a state of low copper status and immune dysfunction. Lowering the dosage normalized these indexes. Zinc absorption in this patient was found to be within the reference range for healthy subjects. At the lower dosage, zinc retention and the rate of whole-body turnover also normalized. These results suggest that the primary lesion in acrodermatitis enteropathica is a cellular defect in zinc metabolism rather than an impairment of zinc absorption.

CONCLUSION

Zinc and copper status and immune function should be monitored regularly in patients with acrodermatitis enteropathica to provide a proper dosage of zinc during different physiologic stages.

No association with HLA class II alleles in Swedish patients with cutaneous manifestations of Lyme borreliosis

The possibility of an association between manifestations of Lyme borreliosis and HLA class II alleles has been investigated with varying results. In the present study, we used genomic typing techniques to determine the DR, DQ and DP allele frequencies in 29 patients with erythema migrans and 36 patients with acrodermatitis chronica atrophicans. We did not find a significant deviation from controls in the distribution of the HLA class II alleles in any of these disease manifestations, nor in the subgroup of 8 patients with acrodermatitis chronica atrophicans and long-standing arthritis. With the additional information obtained by the typing techniques used, our results are thus in accord with those studies where no association between the development of the late disease manifestation acrodermatitis chronica atrophicans and HLA class II alleles has been found.

Serological follow-up after treatment of Borrelia arthritis and acrodermatitis chronica atrophicans

To study the serological response to Borrelia burgdorferi after treatment of late Lyme borreliosis, consecutive serum samples from 20 patients with Borrelia arthritis and 21 with acrodermatitis chronica atrophicans were analysed with capture IgM ELISA and indirect IgG ELISA, both using B. burgdorferi flagella as antigen. Seven patients had positive IgM OD values, whereas all 41 had positive IgG OD values before therapy. In the majority, highly elevated IgG OD values were seen. All patients improved after antibiotic therapy, 32 recovering completely, while 9 had sequelae. At follow-up after 6 months to 5 years, 4/7 patients became negative IgM ELISA, whereas 3 still had slightly elevated IgM OD values 6 months, 1 year and 4.5 years, respectively, after therapy. Only one patient became negative in IgG ELISA during follow-up, although a significant decline in IgG OD values was seen in 22 of the remaining 40 initially IgG-positive patients. The serological response after successful treatment of Borrelia arthritis and acrodermatitis chronica atrophicans may persist for several years even with highly elevated IgG OD values in patients who have recovered completely.

Acrodermatitis chronic atrophicans: a chronic T-cell-mediated immune reaction against Borrelia burgdorferi? Clinical, histologic, and immunohistochemical study of five cases

BACKGROUND

Acrodermatitis chronica atrophicans (ACA) is a late manifestation of infection caused by Borrelia burgdorferi.

OBJECTIVE

Our purpose was to study the clinical, histopathologic, and immunohistochemical findings in patients with ACA to understand better the pathogenesis of the disease.

METHODS

Five patients were studied. Skin biopsy specimens were obtained from active lesions for histologic and immunohistochemical studies.

RESULTS

Clinical lesions included an initial erythematous discoloration in one patient and violaceous infiltrated plaques and nodules in four patients, three of whom also had late atrophic lesions. Biopsy specimens showed a dermal perivascular and interstitial lymphocytic infiltrate with plasma cells. There was a predominance of CD3+, CD4+ T cells in the dermal infiltrate. B cells were present in three patients. The dermal infiltrate showed an intense expression of lymphocyte function-associated antigen. The intercellular adhesion molecule type 1 was expressed on endothelial cells, perivascular mononuclear cells, and focally on basal keratinocytes.

CONCLUSION

Our findings suggest that a chronic, T-cell-mediated immune reaction against B. burgdorferi is involved in the pathogenesis of ACA.

Antibodies to Borrelia burgdorferi in patients with carpal tunnel syndrome

In a study of 94 consecutive patients with neurophysiologically verified carpal tunnel syndrome (CTS) 7/94 had IgG and 0/94 IgM serum titers to Borrelia burgdorferi above the 98th percentile value of age and sex matched controls (n = 127). The difference in prevalence of positive IgG serum titers in patients, compared to controls, was not statistically significant. Even in patients, living in an area, highly endemic for Lyme borreliosis, routine serological screening for borrelia infection does not seem indicated in the investigation of CTS.

A clinical, histological, and immunohistochemical comparison of acrodermatitis chronica atrophicans and morphea

We compared 19 patients with acrodermatitis chronica atrophicans (ACA), a dermatosis caused by Borrelia burgdorferi infection, and 40 patients with morphea, a disease of heterogeneous origin where a borrelia etiology has been suggested in some cases, both clinically and histologically to define the differences between these two dermatoses. Clinically, ACA involves acral body sites with lower temperatures, is seen mostly in elderly persons, and presents as a livid discoloration that is not sharply demarcated. Morphea can be localized in embryonal structures, affects any age and body site, and exhibits extension at the periphery of the lesions. Histologically, ACA shows atrophy of collagen and elastic tissue as well as hypertrophic basophilic elastic tissue; whereas in morphea, sclerosis and polarizing elastic tissue are prominent. Graft-versus-host-like reactions may be present in both dermatoses. Immunohistochemical testing with different lymphocyte markers showed differences only in the expression of HLA-DR antigens. These conditions can be distinguished from each other on a clinical and histological basis in most cases. In 17% of morphea biopsy specimens, however, histological differentiation from ACA was not possible. Moreover, the histological pattern of morphea was not associated with a positive borrelia serology.

Spirochetes in atrophic skin lesions accompanied by minimal host response in a child with Lyme disease

Acrodermatitis chronica atrophicans, which has rarely been observed in the United States, is a late skin manifestation of Lyme borreliosis. A 12-year-old girl who spent summers on Cape Cod presented with a 2-year history of hyperpigmentation and atrophy of the skin on the hands, wrists, and ankles. The skin biopsy specimen of an affected area showed mild dermal fibrosis, a few inflammatory cells, and spirochetes morphologically compatible with Borrelia burgdorferi. An IgG antibody response to B. burgdorferi could be elicited by immunoblotting, but not by enzyme-linked immunosorbent assay. We conclude that this patient had chronic Lyme borreliosis manifested only by indolent infection of the skin.

Comparison of flagellum and sonicate antigens for serological diagnosis of Lyme borreliosis

A sonicate antigen and two concentrations of a purified flagellum antigen of Borrelia burgdorferi were compared for serological diagnosis of Lyme borreliosis by an enzyme immunoassay (EIA). Generally, the higher concentration of flagellum antigen was found to be superior to the lower concentration, which was diluted eight times compared to the higher concentration. The diagnostic sensitivity for IgG antibody detection increased from 13% in the sonicate EIA to 31% in the best flagellum EIA assay (p = 0.01) in sera from patients with erythema migrans (n = 70), and from 34% to 55% (p = 0.01) in sera from patients with neuroborreliosis (n = 77). However, the sensitivity for IgG in sera from patients with acrodermatitis chronica atrophicans (n = 20) was high in both assays: 90% in the sonicate EIA compared to 95% in the flagellum EIA. Regarding IgM, there was no significant difference between the sensitivity of the assays in sera from any of the patient groups. The sensitivity values for IgM and IgG in cerebrospinal fluid (CSF) from patients with neuroborreliosis were also without significant differences. Sera and CSF from patients with meningitis/encephalitis of non-Borrelia etiology (n = 35), multiple sclerosis (n = 9) or syphilis (n = 24), served as controls. The flagellum EIA showed a significantly improved specificity for IgG in CSF from controls with syphilis (p less than 0.01). It is concluded that purified Borrelia burgdorferi flagellum antigen is superior to a sonicate antigen, especially for serodiagnosis of the early stages of Lyme borreliosis.

[An association between hepatitis-B antigen-negative infantile papular acrodermatitis and Epstein-Barr virus infection]

The virological studies on 23 patients with infantile papular acrodermatitis (IPA) without hepatitis B virus (HBV)-associated antigens and antibodies were performed. The following results were obtained; 1) There was serological evidence of primary Epstein-Barr virus (EBV) infection in 17 out of 23 cases (74%). 2) The regression assays was done in 5 cases of IPA and 10 cases of infectious mononucleosis known to be associated with primary EBV infection in order to investigate the development of EBV-specific killer T cell activity in the primary EBV infection. The results confirm the evidence for EBV-specific cellular immunity in both patients with IPA and infectious mononucleosis. 3) The in vitro transformation assays was also done in 4 cases of IPA and 10 cases of infectious mononucleosis. Incidence of in vitro spontaneous transformation in the presence of cyclosporin A was significantly higher in patients of IPA and infectious mononucleosis than in the EBV seropositive controls. These results confirm that EBV plays an important role on the pathogenesis of HBV-negative IPA.

[Acrodermatitis chronic atrophicans and sclerodermiform skin changes in Borrelia infection]

A female patient with acrodermatitis chronica atrophicans and widespread sclerodermiform skin lesions with a high IgG antibody titer against Borrelia burgdorferi is presented. The rapid improvement after high-dose penicillin G therapy and the course of the Borrelia antibody titer suggest a persistence of the causative organism.

Abnormal immune responses during hypozincaemia in acrodermatitis enteropathica

Immune responses were characterized in six patients with acrodermatitis enteropathica during a break in zinc supplementation and during resupplementation. During hypozincaemia the number of T-cells increased but the amount of B-cells and the responses of T- and B-lymphocytes to phytohaemagglutinin, concanavalin A-, pokeweed mitogen- and Staphylococcus aureus stimulations in vitro were subnormal. Cell counts and stimulation results both normalized when serum zinc values improved. One patient was anergic to tuberculin while showing signs of acrodermatitis enteropathica; she converted during supplementation whereas the others were continuously positive. Three females had antibodies against nuclear antigens and slightly elevated serum IgE concentrations; these values were not affected by the break in supplementation. Four females were continuously rheumatoid factor positive. Our findings suggest that zinc deficiency is closely associated with impaired immune responses in patients with acrodermatitis enteropathica, and laboratory markers of autoimmunity occur in a considerable number of the acrodermatitis enteropathica patients, irrespective of their zinc status.

Gianotti-Crosti syndrome: a study of 26 cases

We have studied 26 patients presenting with a symmetrical papular or papulovesicular acrolocated eruption of more than 10 days duration. Mean age at onset was 2 years (range 10 months to 5.75 years). Lymphadenopathy was noted in eight cases, and hepatomegaly in one case. In 12 cases, histopathology and direct immunofluorescence were non-contributory. Cytolytic hepatitis occurred in one case and was associated with HBs antigenemia. A history of recent immunization was given in two cases. There was serological evidence of recent Epstein-Barr virus infection in seven out of 13 cases tested. Coxsackie B viruses were isolated from three patients, and cytomegalovirus was probably associated with the syndrome in one case. We conclude that the Gianotti-Crosti syndrome is not rare in France, and that non-hepatitis B virus (HBV)-associated cases are more frequent than the classical HBV-associated papular acrodermatitis of childhood.

[Etiology of acrodermatitis chronica atrophicans and erythema chronicum migrans]

In Lyme's disease (LD) as well as in the European form of erythema chronicum migrans (ECM), the etiologic agents are spirochetes. As fas as we know by now, these microbes are closely related but not identical. Consequently, LD and ECM should be regarded as closely related but not as identical diseases. The sera of our 21 patients suffering from acrodermatitis chronica atrophicans (ACA) contained elevated antibody titers directed against the etiological agent found in ECM. These findings strongly suggest that ACA is also induced by spirochetes-possibly by the same microbes found in ECM.

Expression of HLA-DQ antigens on keratinocytes in Borrelia spirochete-induced skin lesions

Skin biopsies were investigated with two different immunohistochemical techniques, thus revealing HLA-DQ antigens on HLA-DR-expressing keratinocytes in the late skin manifestations of a Borrelia spirochete infection. In the early skin lesions only HLA-DR antigens were present on the keratinocytes. The invariant gamma chain of class II transplantation antigens was observed on keratinocytes in 1:5 of the late cases. Upon penicillin treatment detectable HLA-DR and HLA-DQ antigens disappeared completely from the keratinocytes. Furthermore, the mononuclear cell infiltrates dominated by anti-Leu 1 and anti-Leu 3a-reactive cells and containing many cells with markers for activation (HLA-DR, HLA-DQ, transferrin, and interleukin 2 receptors) diminished markedly. The possibility that the expression of different class II transplantation antigens on keratinocytes might reflect separate functional demands of these cells or an altered immunological reactivity in the host, is discussed. The precise functional role of the temporary expression of the class II antigens on non-lymphoid cells, however, remains an enigma.

Papular acrodermatitis of childhood associated with hepatitis A virus infection

A 2-year-old girl developed an erythematous papular eruption on her face and extremities a week after an epidemic of hepatitis A had occurred in her school. Clinical and laboratory signs of acute hepatitis, together with serologic verification, confirmed hepatitis A infection. That diagnosis should be considered in the etiology of papular acrodermatitis of childhood.

Gianotti-Crosti syndrome associated with hepatitis B surface antigen (subtype adr)

The Gianotti-Crosti syndrome, papular acrodermatitis of childhood (PAC), is an infrequently recognized disorder with distinctive characteristics. At present hepatitis B virus is thought to be an etiologic agent. The disease is very rare in Korea, in spite of the high frequency of hepatitis B surface antigen (HBsAg) in the general population. It is known that subtype ayw of the HBsAg may influence the pathogenesis of PAC, but subtype analysis of HBsAg in these patients disclosed adr. Therefore, our studies reconfirmed that PAC may in addition be associated with subtype adr of HBsAg. We believe that the lower incidence of PAC in Korea as compared with the high incidence of PAC in other parts of the world, such as in the Mediterranean area, may be due to the fact that a higher predisposition to PAC is conferred by subtype ayw of HBsAg.

Serological diagnosis of erythema migrans disease and related disorders

An indirect immunofluorescence technique for the determination of antibodies against ixodid tick spirochetes is described. Differences in the reactivity between Ixodes ricinus spirochete and Ixodes dammini spirochete antigens were not observed. Cross-reacting antibodies against Treponema pallidum and Treponema phagedenis can be eliminated by quantitative absorption with T. phagedenis. Cross-reactions with leptospira were not observed by immunofluorescence. In the IgM test, false negative reactions caused by high-titered specific IgG antibodies or false positive reactions caused by rheumatoid factor occur. This can be avoided by testing the IgM fraction (19S-IgM-test) or using sera previously treated with anti-IgG serum. Significantly elevated antibody titers against ixodid tick spirochetes were observed in 45% of 44 cases with erythema migrans disease, in 72% of 29 cases of lymphocytic meningoradiculitis, in all of nine patients with acrodermatitis chronica atrophicans and in all of four investigated patients with lymphocytoma (lymphadenosis benigna cutis).
