Assessment of Immune and Clinical Response in Patients with Mucosal Leishmaniasis Treated with Pentavalent Antimony and Pentoxifylline.

Mucosal leishmaniasis (ML) is a severe form of tegumentary leishmaniasis associated with a persistent inflammatory response. High levels of TNF, IFN-γ, CXCL9 and CXCL10 are found in ML patients, and the association of pentoxifylline with antimony is more effective in decreasing the healing time in ML patients when compared to antimony alone. The present study aimed to investigate the existence of a correlation between cytokine and chemokine production and ML severity and evaluate the potential value of cytokine and chemokine production as marker of therapeutic response in ML patients. This prospective study included 86 subjects in an area of endemic Leishmania braziliensis transmission. Patients diagnosed with ML were classified into clinical stages ranging from I to V according to disease severity. TNF, IFN-γ, CXCL9 and CXCL10 levels were quantified in the supernatant of the mononuclear cell cultures by ELISA before and after treatment with antimony alone or antimony plus pentoxifylline. The median TNF level in the group with mild disease (Stages I-II) was 1064 pg/mL (142-3738 pg/mL), while, in the group with moderate or severe disease (Stages III-V), it was 1941 pg/mL (529-5294 pg/mL) (p = 0.008). A direct correlation was observed between ML clinical severity and levels of TNF production (r = 0.44, p = 0.007). Patients who were treated with antimony and pentoxifylline healed significantly faster than those treated with antimony alone (52 vs. 77 days, hazard ratio = 0.60; 95% confidence interval = 0.38-0.95, p = 0.013). Therapeutic failure was higher in the group that received antimony alone (25% vs. 7%; p = 0.041). There was a significant decrease in CXCL9 after therapy of ML in both groups (p = 0.013; p = 0.043). TNF levels are associated with the severity of mucosal diseases, and pentoxifylline associated with antimony should be the recommended therapy for ML in countries where liposomal amphotericin B is not available.

Late Diagnosis of HIV Infection in Metropolitan Areas of the United States and Puerto Rico.

The majority of persons infected with HIV live in large metropolitan areas and many such areas have implemented intensified HIV testing programs. A national indicator of HIV testing outcomes is late diagnosis of HIV infection (stage 3, AIDS). Based on National HIV Surveillance System data, 23.3 % of persons with HIV diagnosed in 2012 had a late diagnosis in large MSAs, 26.3 % in smaller MSAs, and 29.6 % in non-metropolitan areas. In the 105 large MSAs, the percentage diagnosed late ranged from 13.2 to 47.4 %. During 2003-2012, the percentage diagnosed late decreased in large MSAs (32.2-23.3 %), with significant decreases in 41 of 105 MSAs overall and among men who have sex with men. Sustained testing efforts may help to continue the decreasing trend in late-stage HIV diagnosis and provide opportunities for early care and treatment and potential reduction in HIV transmission.

Combination therapy of orally administered glycyrrhizin and UVB improved active-stage generalized vitiligo

Glycyrrhizin has been used clinically for several years due to its beneficial effect on immunoglobulin E (IgE)-induced allergic diseases, alopecia areata and psoriasis. In this study, glycyrrhizin, ultraviolet B light (UVB) or a combination of both were used to treat active-stage generalized vitiligo. One hundred and forty-four patients between the ages of 3 and 48 years were divided into three groups: group A received oral compound glycyrrhizin (OCG); group B received UVB applications twice weekly, and group C received OCG+UVB. Follow-ups were performed at 2, 4, and 6 months after the treatment was initiated. The Vitiligo Area Scoring Index (VASI) and the Vitiligo Disease Activity (VIDA) instrument were used to assess the affected body surface, at each follow-up. Results showed that 77.1, 75.0 and 87.5% in groups A, B and C, respectively, presented repigmentation of lesions. Responsiveness to therapy seemed to be associated with lesion location and patient compliance. Adverse events were limited and transient. This study showed that, although the three treatment protocols had positive results, OCG and UVB combination therapy was the most effective and led to improvement in disease stage from active to stable.

Empeoramiento de la enfermedad de Parkinson y componentes de subtipo motor influencia la condición física / Agravo da doença de Parkinson e subtipo motor influencia componentes da capacidade física / Parkinson's disease severity and motor subtype influence physical capacity components

The severity of Parkinson's disease (PD) and PD's motor subtypes influence the components of physical capacity. The aim of this study was to investigate the impact of both PD severity and motor subtype in the performance of these components. Thirty-six PD patients were assigned into four groups: Tremor (TD) initial and TD mild, akinetic-rigid (AR) initial, and AR mild. Patients' strength, balance, coordination, mobility and aerobic capacity were evaluated and groups were compared using a two-way ANOVA (severity and subtype as factors). AR presents a poorer performance than TD in almost all tests. Also this performance was worsened with the advance of the disease in AR, contrary to TD. We conclude that AR and TD subgroups are different about their performance on physical capacity components, moreover, this performance worsens with the advance of the disease of the AR group, but not for TD.

A doença de Parkinson (DP) é caracterizada por diferentes subtipos motores e supõe-se que o desempenho dos componentes da capacidade física é influenciado por esses subtipos. O objetivo desse estudo foi investigar o impacto que a severidade e o subtipo da DP podem trazer sobre o desempenho dos componentes da capacidade física. Trinta e seis pacientes com DP foram distribuídos em quarto grupos: com dominância de tremor (TD) inicial e TD intermediário ou acinesia (AR) inicial e AR intermediário. A força, equilíbrio, coordenação, mobilidade e capacidade aeróbia foram avaliados. AR apresentou um pior desempenho que TD em nos testes. Esse desempenho foi pior com o aumento da severidade da doença em AR, mas não em TD. Conclui-se que os grupos AR e TD são diferentes em relação ao desempenho dos componentes da capacidade física, mas principalmente, esse desempenho piora com o avanço da doença em AR, mas não em TD.

La enfermedad de Parkinson (EP) se caracteriza por subtipos motor, y se supone que el rendimiento de los componentes físicos de capacidad es influenciada por aquellos subtipos. El objetivo de este estudio fue investigar el impacto tanto de la severidade y subtipo de la PD en el rendimiento de estos componentes. Treinta y seis pacientes con EP se distribuyeron en: Temblor (TD) inicial y TD suave, acinesia (AR) inicial y AR suave. Fuerza, equilibrio, coordinación, la movilidad y la capacidad aeróbica fueron evaluados. AR presenta un desempeño más pobre que TD en las pruebas. También este comportamiento se agravó con el avance de la enfermedad en AR, diferente que en TD. Como conclusión AR y TD son diferentes en respecto a su rendimiento en los componentes físicos de capacidad, pero sobre todo, esto empeora con el aumento de avance de la enfermedad en el grupo de AR, pero no en TD.
