RESUMEN

Abstract: Nail changes are present in about 50% of psoriasis patients and tend to be refractory to conventional treatments. Pulsed dye laser has emerged as an alternative therapy. Our aim is to evaluate the efficacy of pulsed dye laser in nail psoriasis and the impact of treatment on quality of life. Fourteen patients were treated in monthly sessions for three months. The outcome assesment was made by the Nail Psoriasis Severity Index (NAPSI). The median improvement in the scores of the overall NAPSI, nail bed NAPSI, and nail matrix NAPSI were 44.2% (P = 0.002), 50% (P = 0.033) and 65.1% (P = 0.024), respectively.

RESUMEN

Neonatal lupus erythematosus is an autoimmune disease produced by the passage of maternal antinuclear antibodies and extractable nuclear antigen antibodies through the placenta. At the moment of the diagnosis, the mothers are asymptomatic in 40 to 60% of cases. The most common manifestations are cutaneous lesions and congenital heart block. The cutaneous findings are variable and usually begin within the first weeks or months of life. Congenital lupus erythematosus is a congenital variant of neonatal lupus erythematosus. We present one case of congenital lupus erythematosus and one case of neonatal lupus erythematous, showing the variability of this disease.


Lúpus eritematoso neonatal é uma doença auto-imune produzida pela passagem de anticorpos maternos antinucleares e anticorpos contra antígenos extraíveis nucleares através da placenta. No momento do diagnóstico, as mães são assintomáticas em 40 a 60% dos casos. As manifestações mais comuns são lesões cutâneas e bloqueio cardíaco congênito. Os achados cutâneos são variáveis e geralmente começam nas primeiras semanas ou meses de vida. Lúpus eritematoso congênito é uma variante do lúpus eritematoso neonatal. Apresentaremos um caso de lúpus eritematoso congênito e um caso de lúpus eritematoso neonatal, mostrando a variabilidade da doença.

RESUMEN

Human herpesvirus type 6-(HHV-6) has been associated with morbidity after liver transplantation. OBJECTIVE: The aim of this study was to determine the HHV-6 seroprevalence among donor-recipient pairs, analyze the incidence of early active infection, its clinical manifestation, interaction with CMV, and the related morbidity in the first year after kidney transplantation. METHODS: 46 donor-recipient pairs had IgG evaluated by ELISA before transplantation: HHV-6(Pambio - USA) and CMV-(Roche - USA). A frozen whole blood sample collected weekly (from the 1st to the 6th week) was retrospectively tested for HHV-6 viral load (VL) determination by real time quantitative PCR (qPCR, Nanogen - Italy). Patients were preemptively surveyed for CMV by pp65 antigenemia (Ag, APAAP, immunohistochemistry, Biotest - Germany) from the 4th to the 12th week after transplantation. Active infection was defined as qPCR-HHV6+ (viral-load/mL-VL) and Ag+ (+cells/100.000 granulocytes), for HHV-6 and CMV, respectively. DCMV was defined as simultaneous positive antigenemia and suggestive signs/symptoms. Concerning +qPCR-HHV6, associated factors, clinical manifestation, interaction with CMV and morbidity were searched. RESULTS: Pre-transplant HHV-6 seroprevalence was significantly higher among kidney recipients compared to their donors (82.6x54.8%; p = 0.005 [3.9 (1.4-10.4)]). Active infection by this virus occurred in 26.1% (12/46), with no association with previous IgG (p = 0.412). Median VL was 125 copies/mL (53-11.264), and the median Ag was 21 +cells (2-740). There was no association between HHV-6 and CMV activation after transplantation (p = 0.441), neither concerning DCMV (p = 0.596). Median highest Ag+ and days of ganciclovir treatment were similar between qPCR-HHV6 + or - (p = 0.206 and p = 0.124, respectively). qPCR-HHV6+ was associated with higher incidence of bacterial (p = 0.009) and fungal (p = 0.001) infections, and higher number (p = 0.001) of hospital admission and longer duration of hospitalization over the first 6 and 12 months post-transplantation (p = 0.033 and p = 0.001). CONCLUSION: Latent HHV-6 infection is more common among recipients than donors before transplantation. Early active infection by this pathogen after transplantation does not increase DCMV incidence or severity during the first 3 months of follow-up. However, early HHV-6 replication is associated with other infections and hospitalizations in the first year.
