Prevalence of infection by Bartonella spp. in patients with psoriasis

pressed patients (HIV-positive and chronic kidney disease) presented vesicles on an erythematous base; the distribution in one case was dermatomal and in the other the lesions were grouped. These findings are clinically consistent with the Herpesviridae family viruses. In the literature, vesicular lesions similar to varicella are reported, with a more dispersed and diffuse distribution and located on the trunk. Thus, the clinical and evolution characteristics can help to differentiate this particular injury. A polymerase chain reaction test of a sample of the lesion is very useful in the identification of the causative virus. The prevalence of skin lesions observed in the present study was much lower than that found by Recalcati, but similar to that reported by Tammaro. The skin manifestations found in this study are similar to those caused by other viruses, and it cannot be concluded that there is a pathognomonic skin lesion of SARS-CoV-2. As previously reported, no correlation with disease severity was observed. The deficit in the immune system can cause other infections, and the established therapy can also cause skin lesions; therefore, it is essential to carry out detailed studies in each case to make a better differential diagnosis.
