[[Translated article]]BIOBADATOP Spanish Atopic Dermatitis Registry: Description and Early Findings

BACKGROUND

In recent years, remarkable improvements in our understanding of atopic dermatitis (AD) have revolutionized treatment perspectives, but access to reliable data from clinical practice is essential.

MATERIALS AND METHOD

The Spanish Atopic Dermatitis Registry, BIOBADATOP, is a prospective, multicenter database that collects information on patients of all ages with AD requiring systemic therapy with conventional or novel drugs. We analyzed the registry to describe patient characteristics, diagnoses, treatments, and adverse events (AEs).

RESULTS

We studied data entries for 258 patients who had received 347 systemic treatments for AD. Treatment was discontinued in 29.4% of cases, mostly due to a lack of effectiveness (in 10.7% of cases). A total of 132 AEs were described during follow-up. Eighty-six AEs (65%) were linked to a systemic treatment, most commonly dupilumab (39 AEs) and cyclosporine (38 AEs). The most common AEs were conjunctivitis (11 patients), headache (6), hypertrichosis (5), and nausea (4). There was 1 severe AE (acute mastoiditis) associated with cyclosporine.

CONCLUSIONS

Initial findings on AEs from the Spanish BIOBADATOP registry are limited by short follow-up times precluding comparisons or calculation of crude and adjusted incidence rates. At the time of our analysis, no severe AEs had been reported for novel systemic therapies. BIOBADATOP will help answer questions on the effectiveness and safety of conventional and novel systemic therapies in AD.

Colonization with vancomycin-resistant enterococci (VRE) in intensive care unit patients in Cordoba City, Argentina

The purpose of this study was to determine the prevalence of colonization with vancomycin-resistant enterococci (VRE) among intensive care unit (ICU) patients in a hospital in Córdoba, Argentina. We collected 235 rectal swab specimens from 147 ICU patients. Resistance to vancomycin was screened with the disk diffusion method, and MICs were determined with the E-test method. Vancomycin-resistant genotypes were determined by PCR. The VRE strains were isolated from 18/147 patients (12.2%). The isolates were identified as Enterococcus faecium (94.4%), and Enterococcus gallinarum (5.6%). PCR showed that the E. faecium strains carried the vanA gene, and the E. gallinarum strain carried the vanC1 gene. Our study indicated that at least 12.2% of ICU patients were VRE carriers.

Bilateral and subcutaneous palmar nodules in a 2-year-old child suggesting deep granuloma annulare

Granuloma annulare is a benign, relatively common dermatosis in childhood. The subcutaneous form is rare, and lesions typically occur on the legs, buttocks and scalp. We report a case of a deep granuloma annulare confined to the palms of the hands in a 2-year-old child.

Maximal respiratory pressures in myasthenia gravis. Relation to single fiber electromyography

OBJECTIVES

The respiratory muscle weakness was evaluated in mild forms of myasthenia gravis (MG) and was compared with single fiber electromyography results (SFEMG) in the extensor digitorum communis muscle.

MATERIAL AND METHODS

We assessed 61 treated MG patients without clinical respiratory involvement (13 ocular forms, 28 form IIa and 20 form IIb patients) by maximal respiratory pressure (MRP) to ascertain whether they were consistent with SFEMG results.

RESULTS

Maximal expiratory pressure (MEP) and maximal inspiratory pressure (MIP) were reduced below the lower limit for healthy subjects in 85% and 77% of ocular patients; in 93% and 89% of form IIa, respectively; and in 95% of form IIb. The highest percentage of MEP and MIP reduction showed a positive correlation with increased jitter (r=0.45, P<0.001; r=0.27; P<0.05 respectively) and impulse blocking (r=0.35, P<0.01; r=0.28, P<0.05 respectively).

CONCLUSION

We consider MRP measure useful for assessing respiratory muscle weakness in MG patients with subclinical respiratory involvement.

Enzyme-linked immunosorbent assay for detection and quantification of Cryptococcus neoformans antigen

An enzyme-linked immunosorbent assay was standardized for the detection of cryptococcal antigen in serum and cerebrospinal fluid. The system was evaluated in clinical samples from patients infected by human immunodeficiency virus with and without previous cryptococcosis diagnosis. The evaluated system is highly sensitive and specific, and when it was compared with latex agglutination there were not significant differences. A standard curve with purified Cryptococcus neoformans antigen was settled down for the antigen quantification in positive samples.
