Role of Posaconazole in the Treatment of Oropharyngeal Candidiasis Infection and Drug Resistance. 2010 | Pubmed ID: 21694893 Posaconazole is the newest azole antifungal approved by the US Food and Drug Administration, and possesses a broad spectrum of activity against numerous yeasts and filamentous fungi. It is available as an oral suspension and is generally well tolerated by patients, but gastrointestinal absorption is sometimes inadequate and remains a clinical concern in treating deep-seated infections. It is used routinely and effectively for the prophylaxis of invasive fungal infections in immunosuppressed hosts and is an effective treatment of oropharyngeal candidiasis, including azole-resistant disease.
Cat-scratch Disease American Family Physician. Jan, 2011 | Pubmed ID: 21243990 Cat-scratch disease is a common infection that usually presents as tender lymphadenopathy. It should be included in the differential diagnosis of fever of unknown origin and any lymphadenopathy syndrome. Asymptomatic, bacteremic cats with Bartonella henselae in their saliva serve as vectors by biting and clawing the skin. Cat fleas are responsible for horizontal transmission of the disease from cat to cat, and on occasion, arthropod vectors (fleas or ticks) may transmit the disease to humans. Cat-scratch disease is commonly diagnosed in children, but adults can present with it as well. The causative microorganism, B. henselae, is difficult to culture. Diagnosis is most often arrived at by obtaining a history of exposure to cats and a serologic test with high titers (greater than 1:256) of immunoglobulin G antibody to B. henselae. Most cases of cat-scratch disease are self-limited and do not require antibiotic treatment. If an antibiotic is chosen, azithromycin has been shown in one small study to speed recovery. Infrequently, cat-scratch disease may present in a more disseminated form with hepatosplenomegaly or meningoencephalitis, or with bacillary angiomatosis in patients with AIDS.
Antiretroviral Therapy Protects Against Frailty in HIV-1 Infection Journal of the International Association of Providers of AIDS Care. Feb, 2013 | Pubmed ID: 23042791 HIV-1-infected patients are surviving longer and by 2015 half will be older than 50 years of age. Frailty is a syndrome associated with advanced age but occurs in HIV-1-infected patients at younger ages. One hundred outpatient HIV-1-infected persons were prospectively tested for clinical markers of frailty: shrinking weight, slowness in walking, decrease in grip strength, low activity, and exhaustion. Age, length of infection with HIV, CD4 count, HIV-1 RNA, and comorbidities were compared. CD4 counts 350 cells/mm(3) (odds ratio [OR] 9.0, 95% confidence interval [CI] 2.1-44). Seven frail patients were measured 6 months later: 2 died refusing therapy, 4 were no longer frail, and 1 patient remained frail. We conclude that frailty is common in HIV outpatients and is associated with low CD4 counts. However, our data suggest that frailty is transient, especially in younger patients who may revert to their prefrail state unlike uninfected elderly individuals in whom a stepwise decline in function occurs.
