IntroductionRT‐PCR is widely used as a diagnostic test for the detection of SARS‐CoV‐2. In this study, we aim to describe the clinical utility of serial PCR testing in the final detection of COVID‐19.MethodWe collected multiple nasopharyngeal swab samples from patients who had negative RT‐PCR test on the first day after hospitalization. RT‐PCR tests were performed on the second day for all patients with initial negative result. For the patients with secondary negative results on day 2, tertiary RT‐PCR tests were performed on day 3 after hospitalization.ResultAmong 68 patients with initial negative test results, at the end of follow‐up, the mortality number was 20 (29.4%). About 33.8% of patients had subsequent positive PCR test results for the second time and 17.4% of the patients who performed third PCR test had positive result.ConclusionBased on this study, serial RT‐PCR testing is unlikely to yield additional information. 相似文献

We studied 39 AIDS patients from 1989 to 1996, with previous history of herpes zoster. Twelve of them received acyclovir (ACV) secondary prophylaxis. There were 31 males and 8 females, mean age 33.9 years (19-60) during first herpes zoster. Transmission was sexual in 71.8%. Among these 39 patients, 78 herpes zoster episodes occurred. Median CD4 lymphocytes was 18/mm3 (0-232) among the 12 patients with ACV prophylaxis. Mean posology of ACV was 2,400 mg (1,600-4,000) per day, during mean 10 months (median 4 months). ACV prophylaxis was used because of high frequence of herpes zoster (more than 4) (4 cases), neurologic complications in 4 cases (1 myelitis, 1 myeloradiculitis, 1 vascularitis and 1 meningo-encephalitis), disseminated herpes zoster in 4 cases and one hyperalgic zoster. Ten from these 12 patients occurred no zoster recurrence. Among patients without prophylaxis, zoster recurrences were more frequent at 12 months (68% versus 22% among patients with prophylaxis). This prophylaxis seems to be interesting, particularly in deep immunocompromised patients (CD4 < 50/mm3) with serious herpes zoster or frequent recurrences (more than 4). However, since protease inhibitors treatments, zoster incidence is decreasing in HIV+ patients. This prophylaxis will probably be less usefull than before. 相似文献

Hepatitis A (HAV) and B (HBV) vaccination is strongly recommended for HIV-infected patients, especially those with hepatitis C coinfection. The aim of this study was to determine the prevalence of antibodies directed against HAV and HBV in a large cohort of HIV/HCV-coinfected patients, and to identify factors associated with HAV and HBV vaccination.
