Principles of the diagnosis and antibiotic treatment of Lyme borreliosis.

Clinical signs and symptoms are an essential aspect of the diagnosis of Lyme borreliosis. Thus, a thorough knowledge of the clinical features of the disease is important. Established clinical definitions could be of help in everyday clinical practice and especially to compare the findings of different authors or groups. The characteristic sign that permits the diagnosis of Lyme borreliosis is a typical erythema migrans skin lesion. Highly suggestive manifestations are ear lobe lymphocytoma, acrodermatitis chronica atrophicans and Bannwarth's syndrome. The majority of other signs and symptoms are only suggestive and, when expressed individually, may have a very limited or even symbolic value for the purpose of diagnosis. Laboratory confirmation of borrelial infection is needed, as a rule, for all manifestations of Lyme borreliosis with the exception of typical erythema migrans. In clinical practice indirect laboratory methods are usually employed. Determination of borrelial IgM and IgG antibodies by immunofluorescence assays or enzyme-linked immunosorbent assays has not been standardised, and correlation of the results from different laboratories and/or different commercial tests may be poor. Immunoblotting may solve some of the many dilemmas but could (especially in Europe) raise additional questions in a field in which numerous uncertainties already exist. The reliability of methods for direct detection of borrelial infection other than culture to ascertain spirochetes in tissue specimens is open to question. Treatment with antibiotics is reasonable in all stages of Lyme borreliosis and for all clinical manifestations; however, it has been most effective early in the course of the illness. The choice of antibiotic depends upon many factors including the efficacy, pharmacokinetic profile, side effects, expected compliance and price. For the majority of manifestations the most effective antibiotic, the optimal dosage, and the most appropriate duration of treatment have not been exactly determined. Recommendations for the treatment of Lyme borreliosis in Slovenia are presented.

The outcome of Lyme borreliosis in children.

Austria is an endemic area for Lyme borreliosis. The IgG seroprevalence of healthy blood donors as investigated by a DAKO flagellum-ELISA in Graz/Styria is 13%. In order to determine whether this high seroprevalence is caused by infection in childhood, 36 children aged 3 to 18 years (mean, 10.1 years) were followed up over 2 to 20 months (mean, 11.1 months) and reinvestigated for clinical symptoms and antibodies against B. burgdorferi by a commercial flagellum ELISA and a commercial B. garinii Western blot (WB). Twenty-seven children had erythema migrans (EM), one of them with reinfection, 5 had borrelia lymphocytoma (BL), 2 EM and BL, 1 acrodermatitis chronica atrophicans and 1 ACA/circumscribed scleroderma. Before treatment with either phenoxymethylpenicillin, amoxicillin, or minocyclin for 3-4 weeks, 64% of the patients were IgM and 44%, IgG seropositive. Clinically, all but 5 patients with EM recovered from Lyme borreliosis. Among these 5 patients--one of them with reinfection of EM--3 had mild arthralgia, 1 recurrent headache and 1 concentration disturbance. Only 2 children with arthralgia were IgM positive by ELISA and WB. One of 5 BL patients had a persistent swelling of the ear lobe although with a negative serology before and after several antibiotic treatments and at follow up. In 16 children serological investigations were performed after more than 12 months (range, 13-20 months). Eighteen percent of them had IgM antibodies by ELISA, 25% by WB, and 6% IgG antibodies by ELISA and 6% by WB. Although there was a decline of antibody response from 64% to 18% for IgM and from 44% to 6% for IgG as measured by ELISA, children remain seropositive for more than 1 year with or without clinical symptoms. The relevance of the association with clinical symptoms can be raised by combining several diagnostic methods. It is assumed that recurrent, often silent, infections might increase antibody titres. It should be noted that antibody titres also generally increase with the age of individuals.

[Therapy of Lyme borreliosis. Stage-appropriate antibiotic selection and dosage].

When there are good reasons for suspecting Lyme borreliosis, treatment with an antibiotic is mandatory. If the clinical picture clearly shows erythema migrans, antibiotic treatment must be instituted also in the absence of a bacteriological diagnosis. Later manifestations require longer and higher-dose antibiotic treatment. Except acrodermatitis stage II and III manifestations should be treated intravenously. The success of treatment cannot be monitored serologically. A European vaccine is currently being developed.

[Skin manifestations of Lyme borreliosis in patients at the 1st Dermato-venereologic Clinic of Comenius University Medical School in Bratislava 1996-1998].

60-70% of Lyme borreliosis is formed by early manifestations, in particular erythema migrans (EM). All vegetative forms of the tick Ixodes ricinus (e.g. full grown tick, nymphae and larvae) transmit the causal organism, the spirochete Borrelia burgdorferi sensu stricto and Borrelia burgdorferi sensu lato (B. garinii, B. afzelii). The objective of the work was to evaluate clinical and epidemiological parameters and to contribute by testing and investigating in greater detail criteria to the early and exact diagnosis of the disease. In a group of 50 patients the time of development of EM was evaluated, the mode of transmission, the incubation period, localization, symptoms of dissemination of B. burgdorferi, the period of treatment and the antibiotic used. The dynamics of the antibody titre against B. burgdorferi (IFA test) were assessed in 21 patients with EM for a period of 1 to 22 months and in 5 patients with acrodermatitis chronic atrophicans (ACA) for 3 to 55 months. In 50% EM developed during the summer months. 66% reported as the vector a tick, 14% insects and 20% did not know. An incubation of 1 and 2 weeks was reported in 34%, the lower extremities were affected in 52%. Manifestations of dissemination were found in 6 patients, in 2 patients EM relapsed. Antibodies (Ab) against B. burgdorferi were present in 38 patients. In 21 patients the dynamics of the antibody titre were followed up for 1 to 22 months and no substantial changes were found. Serum positivity in patients with ACA persisted without change of the titre for several years. In the treatment of EM most frequently doxycycline was administered for two weeks. EM as the early stage of LB is a seasonal disease with a natural focus. If treatment is started in the early stage of infection, antibodies against B. burgdorferi need not develop. There is no correlation between clinical complaints and serological results and the type of treatment. The prognosis of the disease is favourable in the majority of patients. Vaccination offers new possibilities in active protection against Borrelia infection, in particular in endemic areas. For European countries at present a recombined vaccine is being prepared from the surface lipoprotein A (OspA) made from prevalent strains of B. afzelii and B. garinii.

[Epidemiology of Lyme borreliosis in French-speaking Switzerland].

The purpose of this study was to assess the number of cases and the clinical aspects of Lyme borreliosis in French-speaking Switzerland. From July 1996 to December 1997, all laboratories performing serological tests for Lyme borreliosis sent a questionnaire to the treating physicians whenever the tests were positive. In addition, the physicians who diagnosed a case on clinical grounds only were also asked to report these cases. During this period, 1460 positive serological tests were recorded among approximately 10,360 performed (14%). A total of 775 questionnaires were returned (53%). In 3/4 of the cases, the test was ordered because of an acute clinical manifestation or a tick bite. The rest related to chronic symptoms or follow-up. In 504 cases (65%), diagnosis was considered certain or probable. These were erythema migrans in 46%, clinical manifestations of stage II in 33% (26 facial palsy, 20 acute arthritis, 5 benign cutaneous lymphocytoma) and chronic symptoms in 21% (23 acrodermatitis, 26 neuropathies, and 8 arthritis). The adjusted incidence, estimated on the basis of the treating physician's place of residence, ranged from 9/100,000 in Valais to 95/100,000 in Neuchâtel. This study indicates that Lyme borreliosis is a diagnosis frequently looked for and established in French-speaking Switzerland. Although erythema migrans is the main clinical manifestation, symptoms of stage II and III indicate that Lyme borreliosis is also responsible for relatively major systemic morbidity.

[Culture of Borrelia burgdorferi sensu lato from patients in the Czech Republic].

Spirochete of Borrelia burgdorferi sensu lato were isolated in a modified BSK medium from 26 patients of 275 investigated suffering from early and late borreliosis. The isolates were specified by phenotype and genotype analysis using monoclonal antibodies, by immunochemical methods and by including species specific 16S rRNA, OspA and OspC primers and probes in a polymerase chain reaction with hybridization. Borrelia afzelii was found in 9 patients, Borrelia garinii in 16 and B. burgdorferi sensu stricto in one instance. B. afzelii was isolated from 5 biopsies with erythema migrans. 2 with acrodermatitis chronica atrophicans and from blood of 2 patients with arthritis. B. garinii cultures were prepared from 6 cerebrospinal fluids, 3 blood samples, 1 placenta, 1 liver biopsy and 5 skin samples. Unique was B. burgdorferi detected in a bioptic sample of the heart muscle which was positive on immunohistochemical examination. Monoclonal antibodies against OspA and genotype analysis provided evidence that Borrelia garinii isolates from cerebrospinal fluid are close to serotype IV. One CSF isolate was resistant to antibiotics; the tropism of B. garinii to nervous tissue is contemplated.

[Clinico-epidemiologic characteristics of Lyme disease treated at the Infectious Disease in Novy Sad 1993-1998].

INTRODUCTION: Borrelia burgdorferi, the etiological agent of Lyme disease, is transmitted by the bite of Ixodes ricinus, registered in all parts of Yugoslavia. Vectors are very active in spring and early summer and the disease has a seasonal distribution. Generally speaking, there are three defined stages of the disease, but some of them can be misdiagnosed or really absent. Serological analysis of Lyme disease is very difficult to interpret, especially in later stages, so confirmation by immunoblot assays is recommended. The aim of this study was to present some epidemiologic and clinical characteristics of Lyme disease in Vojvodina in the period from 1993-1998. Throughout this period, 1.659 persons with tick bite were registered, whereas 560 with diagnosed Lyme disease have been treated at the Clinic for Infectious Diseases in Novi Sad. RESULTS: In 511 patients (91.25%) we registered the first stage of the disease, in 42 (7.50%) the second stage and in 7 (1.25%) the third stage of the disease. The mean age of patients with erythema migranes was 38.67 years, mean incubation period was 9.37 days, and tick was removed from the skin after 2.29 days on average. Most of the identified tick bites originated from suburban areas (50.29%), they predominantly occurred in May and June (63.01%), and most of the ticks were removed improperly (57.67%). Dominant clinical manifestations of the second stage were acute meningitis (9.52%), Bannwarth's syndrome (9.52%), arthralgia and arthritis (50%), skin lesions (14.28%), cardiac disorders (11.90%) and mild liver lesions (2.38%) and generalized lymphadenopathy (2.38%). Chronic neuroborreliosis (42.85%), acrodermatitis chronica atrophicans (28.57%) and chronic arthritis were dominant clinical manifestations of the third stage. Up to 81.63% of patients with late stage of disease had a history of previous tick bite. One third of patients were asymptomatic in the first stage of the disease. Improper treatment of the first stage resulted in development of late stage disease in 57.14% of patients. CONCLUSIONS: Morbidity of Lyme disease in Vojvodina is about 1.98-9.8 cases on 100.000 inhabitants, and it belongs to regions with low incidence. Majority of bites are registered during summer months arround cities. Longer persistence of vector on the skin is a risk factor for manifested diseases. Inappropriately treated or completely untreated persons have higher risk for disseminated infection. In our country, most common manifestations of the second stage are neurological and articular manifestations as in the third stage. Leading symptoms and epidemiology aren't enough for diagnosis of Lyme disease, and more specific and sensitive serologic assays are necessary.

Urea cycle disorders in Thai infants: a report of 5 cases.

Urea Cycle Disorders (UCD) is an inborn error of urea synthesis in which ammonium and other nitrogenous precursors of urea accumulate leading to episodic coma and a high mortality rate. Therapy with peritoneal dialysis, essential amino acids or their nitrogen-free analogues has increased survival. The authors report 5 cases of urea cycle disorders, all of whom developed and were rescued from hyperammonemic coma. However, the eventual outcome was quite variable. Argininosuccinate lyase deficiency (ALD) Case 1. A 2 month old male infant, a product of a consanguineous marriage (Suphanburi province); developed poor feeding on day 7, lethargy, convulsion, hepatomegaly and respiratory alkalosis leading to respiratory failure and coma. Hyperammonemia, elevation of glutamic acid and argininosuccinic acid and its anhydrides confirmed the diagnosis of ALD. He is now 9 years old and severely retarded. Case 2. A male infant with history of lethargy, poor feeding on day 3, treated as sepsis and required respiratory support for 6 days; subsequently readmitted at age 2 weeks with vomitting, lethargy, seizure activity and hyperammonemia, and was treated by a local pediatrician in Songkhla province. There was a history of parental consanguinity and he was referred to Siriraj Hospital on day 64 with severe essential amino acid deficiency and acrodermatitis enteropathica with markedly elevated plasma citrulline level. In spite of aggressive treatment; the patient developed sepsis and he expired on day 78. Ornithine transcarbamylase deficiency (OTC) Case 3. An eleven-month-old male infant, the product of a non-consanguineous marriage, developed neonatal onset of hyperammonemia on day 5 after poor feeding, lethargy, hypothermia, seizure, apnea and coma. He was rescued from neonatal hyperammonemic coma on day 9 after aggressive treatment, but expired at eleven months of age after overwhelming sepsis. Case 4. A male infant, sibling of case 3 was referred to Siriraj Hospital on day 8 with hyperammonemia and coma. In spite of intensive genetic counseling given after the birth of their first child with OTC, the couple chose to have another baby without informing any physician. The baby developed vomiting and lethargy on day 2; subsequently hyperammonemia was noted. In spite of aggressive treatment given; hepatic dysfunction, renal failure and disseminated intravascular coagulation defects occurred on day 15. He expired on day 18 after parental permission for discontinuation of all treatment. Argininosuccinate synthetase deficiency (ASS) or Citrullinemia. Case 5. A seven week old female infant, the product of a consanguineous marriage and of Pakistani ethnic origin; developed intermittent vomiting from day 6. Initial diagnoses included ruminations, sepsis and pyloric stenosis for which she was operated on (day 30); however, vomiting continued; subsequently seizures, hyperammonemic coma developed and she was rescued from hyperammonemic coma within 30 hours. Significant elevations of citrulline and L-glutamine were demonstrated. She was discharged in excellent condition to her home in Dubai, the United Arab Emirates.

Solitary borrelial lymphocytoma in adult patients.

During the period from 1986 to 2000, 85 adult patients with solitary borrelial lymphocytoma were diagnosed at the Department of Infectious Diseases, University Medical Centre Ljubljana, Slovenia. There were 36 (42.4%) females and 49 (57.6%) males with a median age of 49 (15-74) years. Borrelial lymphocytoma was located on the breast (nipple--areola mammae region) in 68 (80%) patients, on the ear lobe in eight (9.4%), and in other locations in nine (10.6%). A concomitant erythema migrans enabling clinical diagnosis of Lyme borreliosis was registered or reported in 67 (78.8%) patients. Fifteen (17.6%) patients had no accompanying symptoms, 34 (40%) reported local and constitutional symptoms, 23 (27.1%) recounted only local symptoms, and 13 (15.3%) patients had solely constitutional symptoms. Clinical findings indicating early disseminated borrelial infection were observed at the first visit in 12 (14.1%) patients: six (7.1%) had multiple erythema migrans, one had meningitis, one meningoradiculitis and arthritis, one radiculoneuritis and arthritis, one peripheral facial palsy and concomitant meningitis, and two arthritis. In addition, one of the patients with borrelial lymphocytoma on the breast had acrodermatitis chronica atrophicans. A seropositive response to borrelial antigens was found in 30 (35.3%) patients at the initial examination. In 11/46 (23.9%) patients, infection with Borrelia burgdorferi sensu lato was confirmed by isolation of the agent from lymphocytoma tissue. Eight out of nine (88.9%) typed borrelial strains were found to be B. afzelii, and one (11.1%) B. bissettii. Patients were treated with doxycycline, azithromycin, amoxycillin, cefuroxime-axetil, phenoxymethylpenicillin, or ceftriaxone. Median time to complete disappearance of lymphocytoma was 28 days (range 7-270 days) after the institution of antibiotic treatment; disappearance took longer in patients with prolonged duration of the skin lesion prior to treatment. Treatment failure was registered in 11 (12.9%) patients who were later re-treated. The outcome of borrelial infection assessed at the end of a follow-up period of one year was favourable.

Anetoderma and borreliosis: is there a pathogenetic relationship?

A 32-year-old man simultaneously developed anetoderma and acrodermatitis chronica atrophicans on his left arm and showed a positive serology for borreliosis with ELISA and Western Blot tests. In addition, a 45 year-old man is presented with anetoderma without any associated systemic or cutaneous diseases, with B. afzelii confirmed as a singular causality through serology (ELISA, Western Blot) and amplification of B. afzelii-specific DNA from the skin by PCR. These two observations highly suggest that anetoderma can be the result of an infection with B. afzelii. We conclude that in patients with anetoderma a serological investigation for Borreliosis should be performed.

[Peripheral circulatory disorders and acrocyanosis in arsenic exposed Moselle wine-growers].

Peripheric circulatory disturbances and acrocyanosis in Moselle vinedressers injured by arsenic. During the years 1972--1975 a total number of 100 vine-dressers came for medical treatment because of late injures caused by arsenic intoxication. That is an average of 400 examinations per year 1600 control examinations within four years. These patients belonged to the age-classes 1890--1923, and the average time of exposure to arsenic was 20 years. After years of being exposed to arsenic, and even years after the exposure to it has stopped, there are those so-called late injures caused by arsenic. There are typical arsenic melanisms on the forehad-temple-rim where the hair begins to grow, on the nape of the neck, on the shoulders, chest, arms, and on the back of the hands which pass into precanceroses and carcinomas. The average time until the first late injuries caused by arsenic occur is 26 years. However, there have been latence periods of up to 50 years. This depends mainly on the amount of arsenic absorbed during the time. There are skin alterations which resemble very much an acrodermatitis chronica atrophicans Herxheimer. Histological examinations rather showed the symptoms of an endangiitis obliterans with atrophy of the cutis. These symptoms were found in 60--70% of the 50--60 years old patients, in 80--90% of the 60--70 years old patients, and in 90--95% of the 70--80 years old patients. Simultaneously there are distinct peripheric circulatory disturbances, cyanosis of the lips, dyspnoea, and an emphysema together with typical cardiac insufficiency. Foot and finger pulse are distinctly slower, and the temperature of the skin is remarkably lower. While people grow older the cyanosis gets worse. With a control group of patients who hadn't been exposed to arsenic these symptoms had only been found on 1--2%.

[Viral hepatitis sequelae].

The viral hepatitis is a serious public health problem worldwide. Some problem is hepatitis B, particularly superinfection HBV-HDV and least hepatitis C (HCV), because they are transmitted via parenteral routes. About 20% of patients becomes a chronic carrier. Some chronic carriers are healthy: and they have no functional deficiencies. Others however, chronic active hepatitis develops and can lead to cirrhosis of the liver and finally to hepatocellular carcinoma, that is one of the major cancers of the world today. The immunocomplexes play a role in pathogenesis of several syndromes, such as: polyarthritis nodosa, glomerulonephritis, acrodermatitis. In the study based on questionnaires mailed 645 persons after acute viral hepatitis they were observed: cholecystitis--13.9%, stomach and/or duodenum ulcer--11.5%, and cholelithiasis--8.1%. An important results of the investigation is the conclusion that hepatitis caused distinct decrease of the health condition and change of the lifestyle. After the viral hepatitis 9% of patients shifted to a lighter job for a time, 3.8% for good and 5.6% patients after hepatitis B were receiving disability payment. In the light of the problems discussed here the vaccination would prevent not only the acute liver illness but also the sequelae of the disease.

[Incidence of skin manifestations of Lyme disease in Croatia].

In the study, the most relevant historical data concerning Lyme-borreliosis are shortly reviewed. The most frequent skin manifestations, i.e. erythema cronicum migrans (ECM), lymphocytoma cutis (LCC) and acrodermatitis chronica atrophicans (ACA) are described. The clinical course of Lyme disease and the chronologic review of the most significant data on the disease are given. The frequency of skin manifestations of Lyme-borreliosis in various areas of Croatia from 1988 to 1989 based on the reports of dermatologists throughout Croatia is presented. According to our results, it can be concluded that skin manifestations of Lyme-borreliosis are much more frequent in the central and western parts of Croatia than elsewhere. The authors hope that the use of a fluorescent method for detecting antibodies to Borrelia burgdorferi since 1989 in the Serologic Laboratory of the Department of Dermatology, Salata, Zagreb will lead to more precise results about this disorder in the future.

Maple syrup urine disease presenting with neonatal status epilepticus: report of one case.

Maple syrup urine disease (MSUD) is a rare inborn error of the branched chain amino acid metabolism, which can be classified as classical, intermediate, intermittent, and thiamine responsive types. We report a 16-day-old boy who suffered from difficult feeding, persistent metabolic acidosis, and tricycling movement of the lower legs. Status epilepticus was the initial impression, but classical type MSUD was later diagnosed. Under the diagnosis, dietary therapy effectively prevented further neurological deterioration. However, amino acid deficiency manifested as acrodermatitis enteropathica-like skin rash occurred once. Early parenteral glucose supplementation and periodic plasma amino acid monitoring are very important in the management of metabolic diseases, including MSUD.

[Three bacterial species associated with Lyme borreliosis. CLinical and diagnostic implications].

DNAs from various Borrelia associated with Lyme disease were reciprocally hybridized. This genomic taxonomy method showed that Lyme disease agent comprised three genomic species. Two species could be differentiated by phenotypic characters as major proteins molecular weights and monoclonal antibodies reactivity. Western-blot with sera from patients suffering from different clinical forms of Lyme disease: arthritis, meningoradiculitis and Acrodermatitis Chronicum Atrophicans showed that each of these evolutive forms was preferentially associated with one of the species, respectively: Borrelia burgdorferi sensu stricto, Borrelia garinii and Borrelia group VS 461. Furthermore, geographical repartition of these three species was heterogeneous. B. burgdorferi sensu stricto seems to be the only one present in the United States of America, whereas it coexists in Europe mainly with B. garinii in Western Europe and Borrelia group VS 461 in Northern Europe.

[Guideline 'Lyme borreliosis'].

Borrelia burgdorferi is the causative bacterial agent of Lyme borreliosis, a tick-transmitted infectious disease. The Dutch Institute for Health Care Improvement (CBO) has now issued a guideline on 'Lyme borreliosis'. Lyme borreliosis is classified as 'early', 'early disseminated', 'late' or as 'post-infectious complaints and symptoms'. Erythema migrans is the most common manifestation of early Lyme borreliosis. Frequent neurological manifestations of 'early disseminated Lyme borreliosis' include meningoradiculitis, meningitis and peripheral facial palsy, but Lyme carditis and arthritis also occur. Late Lyme borreliosis is characterised by skin abnormalities (acrodermatitis chronica atrophicans), chronic neuroborreliosis or chronic arthritis. Confirmation serology with respect to Borrelia is the most commonly used laboratory technique, but in early Lyme borreliosis the immune response may be absent. In addition, the mere presence of antibodies in the serum is no proof of an active infection with Borrelia and serology may yield false-positive reactions. Doxycycline and ceftriaxone are the most commonly used antibiotics in the various stages of Lyme borreliosis. Lyme borreliosis may be prevented by avoiding high-risk areas, keeping the skin covered as much as possible, and inspection of the skin after possible exposure to remove ticks within 24 hours. Laboratory tests after a tick bite are not recommended, nor is prophylactic treatment with antibiotics.
