RESUMO

A retrospective study of 109 skin biopsies with granuloma annulare (GA) or morphea histology from patients with suspected tick bite was performed. Biopsies were tested for cutaneous Borrelia burgdorferi DNA using PCR. The same biopsies were analysed for tick-borne novel agents, Chlamydia-related bacteria (members of the Chlamydiales order), using a PCR-based method. Borrelia DNA was detected in 7/73 (9.6%) biopsies with GA and in 1/36 (2.8 %) biopsies with morphea, while Chlamydiales DNA was found in 53/73 (72.6%) biopsies with GA and 25/34 (73.4%) biopsies with morphea. All Borrelia DNA-positive GA samples were also positive for Chlamydiales DNA. The Chlamydiales sequences detected in GA were heterogeneous and contained Waddliaceae and Rhabdochlamydiaceae bacteria, which are also present in Ixodes ricinus ticks, while the Chlamydiales sequences detected in morphea closely resembled those found in healthy skin. In conclusion, tick-mediated infections can trigger GA in some cases, while correlation of either Borrelia or Chlamydiales with morphea is unlikely.

RESUMO

Despite considerable achievements in the study of localized scleroderma, the etiology of the disease has not been investigated completely. Borrelia burgdorferi-the agent of Lyme disease-is suggested to be one of the possible etiological factors of localized scleroderma. However, among scientists, this hypothesis is quite controversial. We have conducted investigations of the level of IgM and IgG class antibodies to B. burgdorferi in the serum of patients with localized scleroderma. To rationally substantiate the role of B. burgdorferi in the occurrence of localized scleroderma, thirty-two patients with localized scleroderma treated at an in-patient department were examined. The level of anti-Borrelia antibodies was determined in ELISA. Diagnostic levels of IgM and/or IgG were detected in 18.8% of patients with localized scleroderma, which is more than in the population (p < 0.01). Positive levels of anti-Borrelia antibodies in patients with localized scleroderma confirm the borreliosis nature of the disease, requiring conduction of complex antimicrobial treatment.

RESUMO

BACKGROUND: Progressive hemifacial atrophy or Parry-Romberg Syndrome (PRS) is a rare, acquired, progressive dysplasia of subcutaneous tissue and bone characterized by unilateral facial involvement. Its etiology is unknown, but theories about its pathogenesis include infectious, degenerative, autoimmune, and traumatic causes among others. The causal relationship of PRS and linear morphea en coup de sabre (LMCS) with Borrelia burgdorferi infection remains controversial. Our goal was to serologically determine anti-B. burgdorferi antibodies in patients diagnosed with PRS and LMCS to establish a possible association as a causative agent. METHODS: We conducted a serology study with patients belonging to a group of 21 individuals diagnosed with PRS, six with LMCS, and 21 matched controls. Anti-Borrelia IgG antibodies were determined by ELISA. A descriptive statistical analysis and Fischer's exact test were done. RESULTS: In serological tests, only two cases had borderline values and were further analyzed by Western blot with non-confirmatory results. For both the PRS and LMCS group, the association test was not significant, suggesting a lack of association between PRS or LMCS and the presence of anti-Borrelia antibodies. CONCLUSION: In Mexico there are no previous studies on Borrelia infection and its relationship between PRS or LMCS. Our result showed a lack of association of either clinical entities with anti-Borrelia-antibodies. Former reports of this association may suggest coincidental findings without causal relationship.

RESUMO

We present a case of a 16-year-old boy with morphea caused by Borrelia burgdorferi. We re-emphasise an immunohistochemical method, focus floating microscopy (FFM), to detect Borrelia burgdorferi spirochetes in tissue sections. Focus floating microscopy (FFM) proved to be more sensitive than polymerase chain reaction (PCR) and nearly equally specific.

RESUMO

Recently, a possible etiological connection between infection with Borrelia burgdorferi and various skin lesions, including morphea and systemic sclerosis (SSc), has been discussed. The aim of our study was the evaluation of frequency of skin thickening typical of SSc or morphea in the group of patients with Lyme disease (LD) with frequent exposition to tick bites. The group consisted of 110 patients with LD frequently exposed to tick bites form the northeastern Poland, which is an endemic area for this disease. To measure the skin lesions, the modified Rodnan total skin score (RTSS) was used. In the analyzed group, no skin changes typical of morphea or skin thickening were found. According to RTSS, all patients scored 0 points. Raynaud's phenomenon in all patients was not found. The relationship between scleroderma or morphea and LD is still a matter of controversy. Described by some authors, cases with LD and scleroderma may be associated with co-existence of B. burgdorferi infection with autoimmune process.

RESUMO

BACKGROUND: In the present study, Borrelia spirochetes were found in four (26.6%) out of 15 patients with Atrophoderma of Pasini and Pierini (IAPP) and lichen sclerosis et atrophicans (LSA) from the Brazilian Amazon Region. MATERIAL AND METHODS: Borreliosis was investigated by immunohistochemistry and focus floating microscopy for Borrelia burgdorferi in skin biopsy samples from 15 patients with both clinical and histopathology evidences compatible with Morphea, LSA, and IAPP. RESULTS: Spirochetes were detected by specific immunohistochemistry and focus floating microscopy for B. burgdorferi in samples from three patients. A limitation of our study was the fact that we were not able to isolate and culture these organisms. CONCLUSION: Our data confirm the presence of borreliosis cases in the Amazon.

RESUMO

Borrelia burgdorferi is the causative agent of Lyme Borreliosis, an infectious multisystemic disease transmitted to humans by the Ixodes ticks bite. A possible association of Borrelia burgdorferi with localized scleroderma has been postulated. However, published data do not provide unequivocal results. Previous serologic analysis of patients with localized scleroderma in South American countries (including Venezuela), have been reported as yielding some reactivity. The present study looked for evidence of Borrelia burgdorferi infection in venezuelan patients with localized scleroderma, using the polymerase chain reaction to analyze 21 skin samples of patients with this skin condition. The results were negative in all the samples studied. Our data do not support an association of Borrelia burgdorferi infection and the sclerotic lesions of localized scleroderma; but do not rule out the possibility of a relationship between localized scleroderma and an unknown geno-specie of Borrelia burgdorferi sensu lato complex, a different Borrelia specie or a different spirochetal organism, as the etiological agents of the skin lesions in this area.

RESUMO

BACKGROUND: Morphea, granuloma annulare (GA) and lichen sclerosus et atrophicans (LSA) have also been suggested to be linked to Borrelia infection. Previous studies based on serologic data or detection of Borrelia by immunohistochemistry and polymerase chain reaction (PCR) reported contradictory results. Thus, we examined skin biopsies of morphea, GA and LSA by PCR to assess the prevalence of Borrelia DNA in an endemic area and to compare our results with data in the literature. METHODS: Amplification of DNA sequences of Borrelia burgdorferi sensu lato by nested PCR from formalin-fixed and paraffin-embedded skin biopsies of morphea, GA and LSA, followed by automated sequencing of amplification products. PCR-based studies on Borrelia species in these disorders published until July 2009 were retrieved by a literature search. RESULTS: Borrelia DNA was detected in 3 of 112 skin biopsies (2.7%) including one of 49 morphea biopsies (2.0%), one of 48 GA biopsies (2.1%) and one of 15 LSA biopsies (6.6%). Amplification products belonged to B. burgdorferi sensu stricto in two cases available for sequence analysis. CONCLUSIONS: The results of our and most of other PCR-based studies do not argue for a significant association of B. burgdorferi sensu lato with morphea, GA, LSA.

RESUMO

The known spectrum of skin manifestations in cutaneous Lyme disease is continuously expanding and can not be regarded as completed. Besides the classical manifestations of cutaneous borreliosis like erythema (chronicum) migrans, borrelial lymphocytoma and acrodermatitis chronica atrophicans evidence is growing that at least in part also other skin manifestations, especially morphea, lichen sclerosus and cases of cutaneous B-cell lymphoma are causally related to infections with Borrelia. Also granuloma annulare and interstitial granulomatous dermatitis might be partly caused by Borrelia burgdorferi or similar strains. There are also single reports of other skin manifestations to be associated with borrelial infections like cutaneous sarcoidosis, necrobiosis lipoidica and necrobiotic xanthogranuloma. In addition, as the modern chameleon of dermatology, cutaneous borreliosis, especially borrelial lymphocytoma, mimics other skin conditions, as has been shown for erythema annulare centrifugum or lymphocytic infiltration (Jessner Kanof) of the skin.

RESUMO

BACKGROUND: Morphea is an inflammatory autoimmune skin sclerosis of unknown etiology. A causative role of Borrelia burgdorferi infection has been controversially discussed, but no conclusive solution has yet been achieved. OBJECTIVE: Intrigued by 3 young patients with severe Borrelia-associated morphea and high-titer antinuclear antibodies, we retrospectively examined the relationship between Borrelia exposure, serologic autoimmune phenomena and age at disease onset in morphea patients. METHODS: In 90 morphea patients the presence of Borrelia-specific serum antibodies was correlated to the age at disease onset and the presence and titers of antinuclear antibodies. Patients with active Borrelia infection or high-titer antinuclear antibodies due to systemic sclerosis or lupus erythematosus served as controls. RESULTS: We observed a statistically highly significant association between morphea, serologic evidence of Borrelia infection, and high-titer antinuclear antibodies when disease onset was in childhood or adolescence. LIMITATIONS: Because pathogenic Borrelia species may vary in different geographic regions the relevance of Borrelia infection in morphea induction may show regional variations. CONCLUSION: B burgdorferi infection may be relevant for the induction of a distinct autoimmune type of scleroderma; it may be called "Borrelia-associated early onset morphea" and is characterized by the combination of disease onset at younger age, infection with B burgdorferi, and evident autoimmune phenomena as reflected by high-titer antinuclear antibodies. As exemplified by the case reports, it may take a particularly severe course and require treatment of both infection and skin inflammation.

RESUMO

BACKGROUND: Morphoea or localized scleroderma is a cutaneous inflammatory disease with still unknown aetiology. Borrelia burgdorferi as causative agent has been discussed controversially. OBJECTIVES: To assess the evidence for infection with B. burgdorferi in patients with morphoea by focus-floating microscopy (FFM). METHODS: Using standard histological equipment, tissue sections stained with a polyclonal B. burgdorferi antibody were simultaneously scanned through in two planes: horizontally as in routine cytology, and vertically by focusing through the thickness of the section, i.e. FFM. Part of the material was also investigated with a Borrelia-specific polymerase chain reaction (PCR). RESULTS: One hundred and twenty-two cases of morphoea and 68 controls (58 negative and 10 positive by PCR) were investigated for the presence of Borrelia within tissue specimens. Using FFM Borrelia was detected in 84 cases (68.9%) of morphoea and in all positive controls, but was absent in all negative controls. Borrelia was significantly more frequent in early inflammatory-rich (75%) than late inflammatory-poor (53%) cases (P = 0.018). What seemed to be vital microorganisms were mostly found close to the active border, while degenerated forms were more common in fibrosclerotic parts. The presence of B lymphocytes determined by CD20 staining proved to be a good positive predictor of the microorganism (correlation 0.85, P < 0.001). Borrelia-specific DNA was detected in only one of 30 cases of morphoea analysed by PCR. CONCLUSIONS: FFM is a reliable and highly sensitive method to detect Borrelia in tissue sections. The frequent detection of this microorganism in morphoea points to a specific involvement of B. burgdorferi or other similar strains in the development of or as a trigger of this disease.

RESUMO

BACKGROUND: Morphea and lichen sclerosus et atrophicus (LSA) are sclerotic skin lesions of unknown etiology involving connective tissue. The hypothesis of a borrelial origin of morphea and LSA is currently controversial. METHODS: Immunoglobulin G (IgG) immunoblot serologies against Borrelia burgdorferi in patients with morphea and LSA were analyzed and compared with those from healthy donors and patients with syphilis to determine the association with a probable borrelial agent in Colombia. RESULTS: No significant differences in the number of reactive antigenic bands were found between morphea/LSA patients and syphilis patients or healthy donors. The presence of at least one of the following bands, p28, p39, or p45, was the criterion most able to distinguish morphea/LSA, yielding a specificity of 95% and a sensitivity of 28.6%. Using this criterion as evidence of putative exposure to a causative borrelial agent, sclerotic skin lesions had an odds ratio of 7.60 (95% confidence interval, 1.47-39.23). CONCLUSIONS: These results could be explained by cross-reactivity; however, the partial shared reactivity of sera from patients with syphilis and morphea/LSA does not rule out the possibility that a new spirochetal agent, unrelated to B. burgdorferi or Treponemas, may be the causative agent of morphea/LSA in Colombia.

RESUMO

AIMS: Previous studies investigating the link between infection with Borrelia burgdorferi and morphoea have produced conflicting results. Often, these studies have been undertaken in patients from different regions or countries, and using methods of varying sensitivity for detecting Borrelia burgdorferi infection. This study aimed to establish whether a relation could be demonstrated in the Highlands of Scotland, an area with endemic Lyme disease, with the use of a sensitive method for detecting the organism. METHODS: The study was performed on biopsies of lesional skin taken from 16 patients from the Highlands of Scotland with typical clinical features of morphoea. After histological confirmation of the diagnosis, a nested polymerase chain reaction (PCR) using primers to a unique conserved region of the Borrelia burgdorferi flagellin gene was performed on DNA extracts from each biopsy. A literature search was also performed for comparable studies. RESULTS: None of the 16 patients had documented clinical evidence of previous infection with B burgdorferi. DNA was successfully extracted from 14 of the 16 cases but all of these were negative using PCR for B burgdorferi specific DNA, despite successful amplification of appropriate positive controls in every test. The results were compared with those of other documented studies. CONCLUSIONS: Examination of the literature suggests that there is a strong geographical relation between B burgdorferi and morphoea. These results, in which no such association was found, indicate that morphoea may not be associated with the subspecies of B burgdorferi found in the Highlands of Scotland.

RESUMO

BACKGROUND: The aetiology of morphoea is still unknown. Borrelia burgdorferi as a causative agent of morphoea has been discussed since 1985, but the relationship remains uncertain. OBJECTIVES: We aimed to find evidence for infection with B. burgdorferi by combined evaluation of different clinical and laboratory data in a group of 54 patients with morphoea. METHODS: In each patient, an evaluation of the case history was performed with regard to infection with B. burgdorferi, using a standardized questionnaire. Questions focused on previous tick bites and skin changes suspicious for erythema migrans (EM). The case history data of 52 patients were compared with those of 104 matched control subjects and of 25 patients with acrodermatitis chronica atrophicans (ACA). Serological examinations were performed in 53 patients with morphoea. Furthermore, lesional skin was examined for borrelial DNA in 33 patients, using nested polymerase chain reaction (PCR) for the ospA and the borrelial rRNA gene. RESULTS: Results of the questionnaire showed no differences between patients with morphoea and matched controls. In contrast, patients with ACA showed a much higher prevalence of tick bites and skin changes suspicious for EM as compared with patients with morphoea. Serological examination was positive in only one patient with morphoea alone and in two additional patients with coexistent ACA. No borrelial DNA was detected by PCR in lesional skin of 33 patients with morphoea. CONCLUSIONS: No evidence was found for B. burgdorferi infection in patients with morphoea.

RESUMO

OBJECTIVES: The role of B. burgdorferi in the etiology of sclerodermia circumscripta (SC) and lichen sclerosus et atrophicus (LSA) are is reported in numerous, however controversial studies. The objective of our study is to approximate the solution of the given problem and to widen these consideration by other diagnoses with multifactorial and unclear etiology such as erythema nodosum (EN), granuloma anulare (GA), erythema anulare (EA) and urticaria chronica. MATERIAL AND METHODS: 124 probands were divided into groups according the diagnoses presented above and compared with the negative control group of 131 probands with dermatologic diagnoses, in which the etiologic agent of B. burgdorferi was not assumed and positive group of 55 probands with lyme boreliosis. Indirect immunofluorescent test was used to find out the tieter of antibodies against B. burgdorferi in all groups by using the endemic strains as antigens, which has caused a higher value of the so-called cut-off. RESULTS: The negative control had a positive titer in 44 cases (n = 131, i.e. in 33.6%). The positive titer was found in 11 probands from the SC group (34.4% =, n = 32), 5 probands in LSA (71.4%, n = 7), 9 probands in the EN group (64.3%, n = 14), 6 probands in the EA and GA groups (42.3%, n = 14) and 19 probands in the group of urticaria chronica (33.3%, n = 57). CONCLUSION: We assume that in the probands with high titers of antibodies, B. burgdorferi could play a role in the etiology of the given diseases titers of antibodies against B. burgdorferi. The draft problem could be solved by modern method including PCR with the use of several primers focused on different antigens regarding the certain epidemiologic regions. (Fig. 7, Ref. 17.)

RESUMO

The aetiology of morphoea and lichen sclerosus et atrophicus is still unknown. Since the detection of Borrelia burgdorferi (B. burgdorferi) as the causative agent of Lyme disease, there has been debate about a possible association between B. burgdorferi and morphoea. Initial serological and cultural studies showed controversial results. The introduction of polymerase chain reaction (PCR) initially suggested an association between B. burgdorferi and morphoea. We reviewed the literature on B. burgdorferi (specific serology, immunohistology, culture, lymphocyte stimulation and DNA detection by PCR) since 1983, using Medline and Current Contents. Histological and immunohistological detection of B. burgdorferi was reported in 0-40% (20 of 82) of the cases with morphoea and in 46-50% (17 of 36) of the cases with lichen sclerosus et atrophicus. Cultivation of spirochetes from lesional skin succeeded in five patients (five of 68) with morphoea, but failed in patients with lichen sclerosus et atrophicus. In Europe and Asia, serological detection of antibodies against B. burgdorferi was described in 0-60% (138 of 609) of patients with morphoea and in 19% (six of 32) in the U.S.A. For lichen sclerosus et atrophicus 0-25% of the published cases (three of 23) in Europe and Asia were seropositive. DNA from B. burgdorferi was detected by PCR in 0-100% (17 of 82) of the tissues of patients with morphoea in Europe and Asia, but not a single case among 98 patients was reported to be positive from the U. S.A. In Europe and Asia, borrelial DNA was detected in 0-100% (nine of 28) of the cases with lichen sclerosus et atrophicus, whereas in the U.S.A. none of 48 patients was positive. There are two possible explanations for these contradictory findings: the most likely is that B. burgdorferi is not a causative agent for morphoea. Another possible explanation could be that a subset of morphoea is caused by a special subspecies of B. burgdorferi that is present in Europe and Asia but does not occur in the U.S.A.
