To evaluate the occurrence of hepatotoxicity in patients during antiretroviral therapy (ART) that contains protease inhibitors and the role of hepatitis viruses in its development, we performed a retrospective study including 1325 HIV-infected patients treated with ART for at least 6 months. Presence or absence of hepatitis viruses, alanine aminotransferase (ALT), total bilirubin, CD4 cell count, and plasma HIV RNA levels were evaluated. Hepatotoxicity developed in a few study subjects without coinfection, whereas it was significantly higher in coinfected patients. Univariate logistic regression analysis showed that viral hepatitis coinfections are independent risk factors for hepatotoxicity. After 6 months of treatment, ritonavir was associated with higher rates of severe hepatotoxicity in the coinfected group; in fact, ritonavir seems to be the most strongly hepatotoxic agent among coinfected patients. After 12 months of therapy, hepatotoxicity occurred more frequently in patients with hepatitis C virus who did not respond to antiretroviral therapy (ART), whereas patients who did respond to ART showed decreased ALT levels. Hepatotoxicity is not exclusively an effect of drug toxicity, and the presence of hepatitis coinfection is an independent risk factor. Moreover, chronic hepatotoxicity mainly occurs in patients who did not respond to therapy. Conversely, patients who did respond to ART seemed to show improvement of chronic liver infection.

SARS-CoV-2 infection shows a wide-ranging clinical severity, requiring prognostic markers. We focused on S100B, a calcium-binding protein present in biological fluids, being a reliable biomarker in disorders having inflammatory processes as common basis and RAGE as main receptor. Since Covid-19 is characterized by a potent inflammatory response also involving RAGE, we tested if S100B serum levels were related to disease severity. Serum samples (n = 74) were collected from hospitalized SARS-CoV-2 positive patients admitted to Covid center. Illness severity was established by admission clinical criteria and Covid risk score. Treatment protocols followed WHO guidelines available at the time. Circulating S100B was determined by ELISA assay. Statistical analysis used Pearson’s χ2 test, t-Test, and ANOVA, ANCOVA, Linear Regression. S100B was detected in serum from Covid-19 patients, significantly correlating with disease severity as shown both by the level of intensity of care (p < 0.006) as well by the value of Covid score (Multiple R-squared: 0.3751); the correlation between Covid-Score and S100B was 0.61 (p < 0.01). S100B concentration was associated with inflammation markers (Ferritin, C-Reactive Protein, Procalcitonin), and organ damage markers (Alanine Aminotransferase, Creatinine). Serum S100B plays a role in Covid-19 and can represent a marker of clinical severity in Sars-CoV-2 infected patients.

Our results demonstrate a statistically significant correlation of aminotransferase values with the histological parameters, and an even stronger correlation with the AST values. Our study therefore suggests that aminotransferase values, especially AST, may correlate with liver damage.

We report a case of Hymenolepis diminuta infection in an Italian child affected by tuberous sclerosis. Praziquantel is the drug of choice for the treatment of H. diminuta infection. However, considering the patient's neurological disease, we decided to use not praziquantel but niclosamide, which proved equally effective. CASE REPORTA 2-year-old boy living in the urban area of Rome, Italy, was referred to the Department of Tropical and Infectious Diseases of the University of Rome "La Sapienza" owing to the emission of tapeworm proglottids in his stool. In the previous 2 weeks, the patient had episodes of itching and nocturnal restlessness. His medical history was positive for tuberous sclerosis with no overt neurological complications other than seizures that were controlled with diazepam. The results of a physical examination were normal. No abnormalities were revealed by blood and urine analyses. Macroscopic and microscopic tapeworm examinations were suggestive of Hymenolepis diminuta proglottids. The parasitological examination of concentrated stool samples revealed spherical eggs, 70 m in diameter, with a striated outer membrane and a thin inner membrane and containing six central hooklets but no polar filaments (Fig. 1); they were identified as H. diminuta eggs and differentiated from H. nana eggs, which have a similar appearance but are smaller and have two evident polar thickenings, from each of which arise four to eight polar filaments. Owing to the possible convulsant effect of praziquantel, oral niclosamide (1 g for the first day, 500 mg/day for the following 6 days) was prescribed (1, 3). Parasitological stool examinations 7, 9, 15, and 30 days after the end of treatment were negative for H. diminuta eggs.

The Coronavirus Disease (Covid-19) pandemic is rapidly spreading across the world, representing an unparalleled challenge for health care systems. There are differences in the estimated fatality rates, which cannot be explained easily. In Italy, the estimated case fatality rate was 12.7% in mid-April, while Germany remained at 1.8%. Moreover, it is to be noted that different areas of Italy have very different lethality rates. Due to the complexity of Covid-19 patient management, it is of paramount importance to develop a well-defined clinical workflow in order to avoid the inconsistent management of patients. The Integrated Care Pathway (ICP) represents a multidisciplinary outline of anticipated care to support patient management in the Sant’Andrea Hospital, Rome. The main objective of this pilot study was to develop a new ICP evaluated by care indicators, in order to improve the COVID-19 patient management. The suggested ICP was developed by a multi-professional team composed of different specialists and administrators already involved in clinical and management processes. After a review of current internal practices and published evidences, we identified (1) the activities performed during care delivery, (2) the responsibilities for these activities, (3) hospital structural adaptation needs and potential improvements, and (4) ICP indicators. The process map formed the basis of the final ICP document; 160 COVID-19 inpatients were considered, and the effect of the ICP implementation was evaluated over time during the exponential phase of the COVID-19 pandemic. In conclusion, a rapid adoption of ICP and regular audits of quality indicators for the management of COVID-19 patients might be important tools to improve the quality of care and outcomes.
