"Say Ninetynine": It's Never too Late to Recover from COVID-19.

COVID-19, the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, showed higher severity and lethality in male older adults . There are currently no specific treatments. Studies are evaluating the efficacy of monoclonal antibodies against interleukin-6 receptor. Here we present the case of a 98-years old man admitted to our COVID-Hospital with acute respiratory failure. Comprehensive geriatric assessment showed no signs of frailty. First-line therapy with hydroxychloroquine and anticoagulants was not effective. Patient was administered intravenous monoclonal antibodies, and he showed remarkable clinical improvement. This case suggests that age alone should not preclude access to new therapeutic approaches. Comprehensive, multisciplinary, multidomain approaches are needed to develop patient-tailored treatments against COVID-19.

Lamivudine-based maintenance antiretroviral therapies in patients living with HIV-1 with suppressed HIV RNA: derivation of a predictive score for virological failure.

OBJECTIVES: Two-drug antiretroviral regimens based on lamivudine (3TC) plus either a protease inhibitor (PI) or dolutegravir (DTG) are becoming increasingly popular in switch strategies. Our goal was to derive a predictive score for virological failure (VF). METHODS: We retrospectively analysed data for a cohort of 587 virologically suppressed (HIV RNA < 37 HIV-1 RNA copies/mL), adult (≥ 18 years old) patients starting lamivudine plus either a boosted PI or dolutegravir. Predictors of VF (defined as a single HIV RNA measurement ≥ 1000 copies/mL or two consecutive HIV RNA measurements ≥ 50 copies/mL) were identified using a multivariate Cox regression model. A 'weighted' score was assigned to each variable associated with VF; the discriminative power of the score obtained was expressed as the area under the receiver-operator characteristic curve (ROC-AUC). RESULTS: During a median 2 years of follow-up time, 35 VFs occurred; predictors of VF were baseline residual HIV RNA between 20 and 36 copies/mL, African ethnicity, ≥ 10 therapeutic lines, the presence of at least one resistance-associated mutation (RAM) for resistance to current drugs (excluding M184V), a non-B viral subtype and a baseline CD4 count < 200 cells/µL. A score of 2 was assigned to non-B viral subtype, 3 to residual viraemia ≥ 20 copies/mL, ≥ 10 previous therapeutic lines and African ethnicity, 4 to baseline CD4 count < 200 cells/µL, and 7 to the presence of at least one RAM (excluding M184V). The ROC-AUC was 0.67 (95% confidence interval 0.57-0.77). CONCLUSIONS: The presence of at least one RAM, higher residual viraemia and African ethnicity were among the major predictors of VF in our cohort. Studies with larger sample sizes are warranted to improve the predictive value of the derived score.

Trends of hospitalisations rates in a cohort of HIV-infected persons followed in an Italian hospital from 1998 to 2016.

Here we evaluated hospitalisation rates and associated risk factors of human immunodeficiency virus (HIV)-infected individuals who were followed up in an Italian reference hospital from 1998 to 2016. Incidence rates (IR) of hospitalisations were calculated for five study periods from 1998 to 2016. The random-effects Poisson regression model was used to assess risk factors for hospitalisation including demographic and clinical characteristics. To consider that more events may occur for the same subject, multiple failure-time data analysis was also performed for selected causes using the Cox proportional hazards model. We evaluated 2031 patients. During 13 173 person-years (py) of follow-up, 3356 hospital admissions were carried out for 756 patients (IR: 255 per 1000 py). IR decreased significantly over the study period, from 634 in 1998-2000 to 126 per 1000 py in 2013-2016. Major declines were detected for AIDS-defining events, non-HIV/AIDS-related infections and neurological diseases. Older age, female sex, longer HIV duration and HCV coinfection were associated with a higher hospitalisation risk, whereas higher CD4 nadir and antiretroviral therapy were associated with a reduced risk. Influence of advanced HIV disease markers declined over time. Hospitalisation rates decreased during the study period in most causes. The relative weight of hospitalisations for non-AIDS-related tumours, cardiovascular, respiratory and kidney diseases increased during the study period, whereas those for AIDS-defining events declined.

An outbreak of acute hepatitis A among young adult men: clinical features and HIV coinfection rate from a large teaching hospital in Rome, Italy.

OBJECTIVES: Italy is a low-incidence region for hepatitis A; however, during the last 2 years an increase in the incidence of hepatitis A virus (HAV) infection was reported in Europe. The aim of this study was to describe this recent outbreak. METHODS: We retrospectively analysed all cases of acute hepatitis A diagnosed at our laboratory between January 2010 and June 2017. We evaluated the following variables at the time of diagnosis: sex, age, nationality, glutamic oxaloacetic transaminase (GOT/AST), glutamic pyruvic transaminase (GPT/ALT), bilirubin concentration, international normalized ratio (INR) and the presence or absence of anti-HIV-1/2 antibodies. Hospitalization was also considered. We analysed these parameters using the χ2 test and Mann-Whitney U-test. RESULTS: A total of 225 cases were analysed; 82.7% were in male patients, 94.2% were in Italians and the median age of the patients was 36.4 years. At diagnosis, the median GOT value was 306 U/L, the median GPT was 1389 U/L, and the median total bilirubin value was 5.88 mg/dL. Hospitalization was required for 142 patients, with a median duration of hospital stay of 8.5 days. In 2016-2017 we registered 141 cases, with a higher prevalence of male patients, higher GPT values and a higher prevalence of patients aged 20-39 years compared with older (2010-2015) cases. Homosexual intercourse was reported as the HAV risk factor in 70.2% of patients. HIV serology was available for 120 patients: 24 were HIV-positive, four of whom represented new diagnoses. HIV-positive patients showed lower bilirubin and GPT values and fewer hospitalizations than HIV-negative patients. CONCLUSIONS: In 2016-2017, we saw a rise in the number of hepatitis A cases, with a higher prevalence of adult male patients. No significant differences regarding the prevalence of HIV coinfection emerged.

Serum and urine biomarkers for human renal cell carcinoma.

Renal cell carcinoma (RCC) diagnosis is mostly achieved incidentally by imaging provided for unrelated clinical reasons. The surgical management of localized tumors has reported excellent results. The therapy of advanced RCC has evolved considerably over recent years with the widespread use of the so-called "targeted therapies." The identification of molecular markers in body fluids (e.g., sera and urine), which can be used for screening, diagnosis, follow-up, and monitoring of drug-based therapy in RCC patients, is one of the most ambitious challenges in oncologic research. Although there are some promising reports about potential biomarkers in sera, there is limited available data regarding urine markers for RCC. The following review reports some of the most promising biomarkers identified in the biological fluids of RCC patients.
