Pathogenetic implications of the age at time of diagnosis and skin location for acrodermatitis chronica atrophicans.

Background: The pathogenesis of acrodermatitis chronica atrophicans (ACA) is not well understood.

Objective: The purpose of this study was to gain a better understanding of ACA by utilizing a large data set of adult Slovenian patients with Lyme borreliosis.

Methods: The age of 590 ACA patients was compared with that of patients with other manifestations of Lyme borreliosis.

Are patients with erythema migrans who have leukopenia and/or thrombocytopenia coinfected with Anaplasma phagocytophilum or tick-borne encephalitis virus?

Lyme borreliosis (LB), tick-borne encephalitis (TBE) and human granulocytic anaplasmosis (HGA) are endemic in central part of Slovenia. We tested the hypothesis that patients with erythema migrans (EM) from this region, who have leukopenia and/or thrombocytopenia (typical findings in HGA and in the initial phase of TBE but not in patients with LB) are coinfected with Anaplasma phagocytophilum and/or with TBE virus, i.e.

Clinical characteristics associated with Borrelia burgdorferi sensu lato skin culture results in patients with erythema migrans.

Clinical characteristics associated with isolation of Borrelia burgdorferi sensu lato from skin have not been fully evaluated. To gain insight into predictors for a positive EM skin culture, we compared basic demographic, epidemiologic, and clinical data in 608 culture-proven and 501 culture-negative adult patients with solitary EM. A positive Borrelia spp.

Comparison of isolation rate of Borrelia burgdorferi sensu lato in two different culture media, MKP and BSK-H.

The aim of the study was to evaluate two culture media for Borrelia burgdorferi sensu lato isolation from a 5 × 2 × 2 mm skin biopsy that was dissected into two pieces and inoculated into modified Kelly-Pettenkofer (MKP) and Barbour-Stoenner-Kelly-H (BSK-H) medium. Samples were incubated at 33°C for up to 9 weeks. Borrelia species was determined by MluI-restriction of whole genome or by MseI-restriction of PCR product.

Gender disparity between cutaneous and non-cutaneous manifestations of Lyme borreliosis.

Cutaneous manifestations of Lyme borreliosis in Europe include erythema migrans (EM) and acrodermatitis chronica atrophicans (ACA); the most common non-cutaneous manifestations are Lyme neuroborreliosis (LNB) and Lyme arthritis. The purpose of this study was to evaluate the gender distribution of patients with these clinical manifestations of Lyme borreliosis. Data on gender were obtained from the clinical records of patients with Lyme borreliosis aged ≥15 years who had been evaluated at the University Medical Center Ljubljana, Ljubljana, Slovenia.
