COVID-19 in patients with thymic epithelial tumors with or without Good's syndrome: a single-center retrospective study.

INTRODUCTION: Thymic epithelial tumors (TETs) are rare neoplasms often associated with immune-related disorders. Patients with Good's syndrome (GS), an adult-acquired TET-related immunodeficiency, are at a high risk of mortality due to infectious diseases. This study aims to examine COVID-19 occurrence and severity in TET patients, with or without GS. METHODS: Clinical records of TET patients referred to the Regional Coordinating Center for Rare Tumors of Campania Region were retrospectively collected. During the observation period, elapsing from March 2020 to April 2023, the following data were collected: occurrence of SARS-CoV-2 infection; COVID-19 severity, according to the National Institute of Health (NIH) illness categories; COVID-19 treatment. COVID-19 occurrence and severity were assessed in the overall population and correlated with the presence of GS and/or other immune-related dysregulations. RESULTS: Overall, 47 TET patients were included in the study; 27 of these (57.4%) had GS. All participants had received a full cycle of mRNA vaccine for SARS-CoV2., Thirty-one patients (66.0%) experienced COVID-19, of whom 18 (58.0%) had previously received a diagnosis of GS. No significant association of GS and/or other immune-related dysregulations with SARS-CoV-2 infection occurrence was detected (Fisher's exact test p = 1 and p = 0.3587, respectively). Among patients with GS, 8 (45.0%) reported a COVID-19 severity score of ≥ 3; whereas, only 1 of the 13 patients without GS (7.7%) had a severity score of ≥ 3. The correlation between presence of GS and COVID-19 severity (score 1 or 2 vs. ≥ 3) was statistically significant (p = 0.0448). No statistically significant association between COVID-19 severity and other immune-related syndromes were found (p = 1). Of note, all the hospitalized patients for NIH 4 and 5 COVID-19 had GS. CONCLUSIONS: Our data suggest that TET patients, especially those with GS, require a careful multidisciplinary monitoring for SARS-CoV-2 infection, in order to establish tailored treatments and prophylactic protocols.

Optimizing COVID-19 treatment in immunocompromised patients: early combination therapy with remdesivir, nirmatrelvir/ritonavir and sotrovimab.

BACKGROUND: Morbidity and mortality are higher in immunocompromised patients affected by COVID-19 than in the general population. Some authors have successfully used antiviral combination, but never in the early phase of the infection. METHODS: We conducted a retrospective cohort study to determine the efficacy and safety of the combination of two antivirals, with and without a monoclonal antibody (mAb), in both the early (within 10 days of symptoms) and in a later phase (after 10 days) of SARS-CoV-2 infection in immunocompromised patients admitted to our Facility. RESULTS: We treated 11 patients (seven in an early phase and four in a late phase of COVID-19) with 10 days of intravenous remdesivir plus five days of oral nirmatelvir/ritonavir, also combined with sotrovimab in 10/11 cases. Notably, all the "early" patients reached virological clearance at day 30 from the end of the therapy and were alive and well at follow-up, whereas the corresponding numbers in the "late" patients were 50% and 75%. Patients in the "late" group more frequently needed oxygen supplementation (p = 0.015) and steroid therapy (p = 0.045) during admission and reached higher COVID-19 severity (p = 0.017). DISCUSSION: The combination of antiviral and sotrovimab in the early phase of COVID-19 is well tolerated by immunocompromised patients and is associated with 100% of virological clearance. Patients treated later have lower response rates and higher disease severity, but whether therapy plays a causative role in such findings has yet to be determined.

Treatment-based risk stratification of infections in inflammatory bowel disease: A comparison between anti-tumor necrosis factor-α and nonbiological exposure in real-world setting.

BACKGROUND AND AIM: Infective issues about anti-tumor necrosis factor (TNF)-α agents in inflammatory bowel disease (IBD) remain controversial, especially when compared with nonbiological treatments. This study aimed to evaluate the incidence and prevalence of several infections in anti-TNF-α-exposed patients compared with nonbiological treatments. METHODS: All naïve IBD subjects treated with anti-TNF-α and matched nonbiologic-exposed patients were included. RESULTS: Among 3453 patients in the database, 288 anti-TNF-α-exposed subjects and 288 nonbiologic-exposed IBD controls met inclusion criteria. Fifty-eight infections (20.1%) occurred during anti-TNF-α treatment versus 23 (8%) in the matched group (odds ratio [OR] 2.9, P < 0.001) (incidence 5.72 vs 0.96/100 patient-years, incidence ratio [IR] 6, P < 0.001). IR was higher for anti-TNF-α versus mesalamine/sulfasalazine (IR 40.8, P < 0.001), similar to azathioprine/6-mercaptopurine/methotrexate (IR 0.78, P = 0.32) and lower than corticosteroids (IR 0.05, P < 0.001). The incidence rate of serious infections was 1.3 in the anti-TNF-α-exposed versus 0.38/100 patient-years in nonexposed subjects (IR 3.44, P = 0.002), without significant difference between anti-TNF-α and azathioprine/6-mercaptopurine/methotrexate (1.3 vs 3.03/100 patient-years, IR 0.43, P = 0.1). Predictors of infections in anti-TNF-α-exposed patients were concomitant use of systemic steroids (OR 1.9, P = 0.02) or azathioprine (OR 2.6, P = 0.01) and a body mass index < 18.5 at time of infection (OR 2.2, P = 0.01). CONCLUSIONS: The risk of developing infections during anti-TNF-α therapy remains high, although not dissimilar to that found for other immunosuppressants, while concomitant immunosuppression and malnutrition appear the most important causes of infection.

Resolution of autoimmune thrombocytopenia associated with raltegravir use in an HIV-positive patient.

About 10% of the human immunodeficiency virus (HIV) patients show thrombocytopenia. We describe the case of an HIV/HCV-positive patient whose autoimmune thrombocytopenia resolved with the addition of raltegravir to previous highly active antiretroviral therapy (HAART). It is noteworthy that the effect on platelet count appeared to be independent of viral load suppression, which was achieved with previous antiretroviral regimens. In fact, it has been suggested that the positive effect exerted by raltegravir on autoimmune diseases is due to its inhibition on herpes viruses, and hence on activation of endogenous human retroviruses. This consideration, if confirmed, could open new avenues in the treatment of autoimmune thrombocytopenia in the HIV setting.

Remdesivir Alone or in Combination with Monoclonal Antibodies as an Early Treatment to Prevent Severe COVID-19 in Patients with Mild/Moderate Disease at High Risk of Progression: A Single Centre, Real-Life Study.

Early treatment with antivirals against SARS-CoV-2 infection can prevent the onset of severe COVID-19 in fragile and immunocompromised patients. In this real-life, prospective, observational study, we evaluated efficacy and safety of a 3-day early treatment with remdesivir in adult and fragile patients with a diagnosis of SARS-CoV-2 infection who referred to the COVID-19 early treatment service of Infectious Diseases Unit of University of Naples Federico from 10 January 2022 to 31 March 2022. The included patients could be treated with either remdesivir alone or with remdesivir plus a monoclonal antibody with activity against SARS-CoV-2. Among the 62 included patients, we showed low rates of hospitalization (8%), increase in oxygen supplementation (3.2%), ICU admission (1.6%) and death (1.6%). The rate of disease progression was 8% and it was similar in patients treated with remdesivir alone or in combination with monoclonal antibodies (6.7% and 9.4%, respectively; p = 0.531). The rate of adverse drug reaction was low and similar in the two groups (13.3% in patients treated with remdesivir, 15.6% in patients treated with the combination; p = 0.543). Most common adverse events were headache and fever. In conclusion, in our cohort of patients at a high risk of worse COVID-19 outcomes, an early course of remdesivir showed low rates of disease progression and adverse drug reactions.

Casirivimab/imdevimab + remdesivir in hospitalized patients with severe Covid-19: A single centre experience.

Since 2020, COVID-19 pandemic has spread worldwide causing a huge number of cases and casualties. Among direct anti SARS-CoV-2 agents available for the treatment of COVID-19, only remdesivir and casirivimab/imdevimab have been approved for severe disease. As they act at different levels in blocking viral replication, it is theoretically possible to combine them. In this case series we describe tolerability, safety and effectiveness in a small group of 14 patients of the combination of casirivimab/imdevimab monoclonal antibodies with the polymerase inhibitor remdesivir for the treatment of severe COVID-19. We conducted a retrospective study among consecutive patients admitted to the Infectious Disease ward of the University of Naples (Italy) Hospital for COVID-19 that received the combination of casirivimab/imdevimab and remdesivir for the treatment of severe COVID-19 from the August 1, 2021 to the November 30, 2021. During the study period, 78 patients were admitted for severe COVID-19. Fourteen patients (18%) received the combination casirivimab/imdevimab and remdesivir. They were five males and nine females with a median age of 54 years. Eight patients had significant comorbidities; three patients were in the immediate post-partum period. No adverse drug reaction was observed. All patients except one improved clinical condition and respiratory parameters within seven days following the therapy. All patients were discharged in good conditions.

Risk Factors for Pneumocystis jirovecii Pneumonia in Non-HIV Patients Hospitalized for COVID-19: A Case-Control Study.

BACKGROUND: Very few cases of Pneumocystis jirovecii pneumonia (PJP) have been reported in COVID-19 so far, and mostly in patients with concomitant HIV infection or in solid-organ transplant recipients. Despite COVID-19 being associated with lymphopenia and the use of steroids, there are no studies specifically aimed at investigating the risk factors for PJP in COVID-19. METHODS: A retrospective case-control study was performed. We matched PJP cases with controls with a 1:2 ratio, based on age ± 10 years, solid-organ transplantation (SOT), hematological malignancies, and in the setting of PJP development (ICU vs. non-ICU). A direct immunofluorescence assay on bronchoalveolar lavage fluid was used to diagnose PJP. RESULTS: We enrolled 54 patients. Among 18 cases of PJP, 16 were diagnosed as "proven". Seven of the eighteen cases were immunocompromised, while the other patients had no previous immunological impairment. Patients with PJP had significantly lower median lymphocyte values (p = 0.033), longer COVID-19 duration (p = 0.014), a higher dose of steroid received (p = 0.026), higher CRP values (p = 0.005), and a lower SARS-CoV-2 vaccination rate than the controls (p = 0.029). Cumulative steroid dose is the independent risk factor for PJP development (OR = 1.004, 95%CI = 1-1.008, p = 0.042). CONCLUSIONS: PJP develops in COVID-19 patients regardless of immunosuppressive conditions and the severity of disease, and it is correlated to the corticosteroid dose received.

Efficacy and Safety of Reparixin in Patients with Severe COVID-19 Pneumonia: A Phase 3, Randomized, Double-Blind Placebo-Controlled Study.

INTRODUCTION: Polymorphonuclear cell influx into the interstitial and bronchoalveolar spaces is a cardinal feature of severe coronavirus disease 2019 (COVID-19), principally mediated by interleukin-8 (IL-8). We sought to determine whether reparixin, a novel IL-8 pathway inhibitor, could reduce disease progression in patients hospitalized with severe COVID-19 pneumonia. METHODS: In this Phase 3, randomized, double-blind, placebo-controlled, multicenter study, hospitalized adult patients with severe COVID-19 pneumonia were randomized 2:1 to receive oral reparixin 1200 mg three times daily or placebo for up to 21 days or until hospital discharge. The primary endpoint was the proportion of patients alive and free of respiratory failure at Day 28, with key secondary endpoints being the proportion of patients free of respiratory failure at Day 60, incidence of intensive care unit (ICU) admission by Day 28 and time to recovery by Day 28. RESULTS: Of 279 patients randomized, 182 received at least one dose of reparixin and 88 received placebo. The proportion of patients alive and free of respiratory failure at Day 28 was similar in the two groups {83.5% versus 80.7%; odds ratio 1.63 [95% confidence interval (CI) 0.75, 3.51]; p = 0.216}. There were no statistically significant differences in the key secondary endpoints, but a numerically higher proportion of patients in the reparixin group were alive and free of respiratory failure at Day 60 (88.7% versus 84.6%; p = 0.195), fewer required ICU admissions by Day 28 (15.8% versus 21.7%; p = 0.168), and a higher proportion recovered by Day 28 compared with placebo (81.6% versus 74.9%; p = 0.167). Fewer patients experienced adverse events with reparixin than placebo (45.6% versus 54.5%), most mild or moderate intensity and not related to study treatment. CONCLUSIONS: This trial did not meet the primary efficacy endpoints, yet reparixin showed a trend toward limiting disease progression as an add-on therapy in COVID-19 severe pneumonia and was well tolerated. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04878055, EudraCT: 2020-005919-51.

A Simple Non-Invasive Score Based on Baseline Parameters Can Predict Outcome in Patients with COVID-19.

We evaluated the role of CRP and other laboratory parameters in predicting the worsening of clinical conditions during hospitalization, ICU admission, and fatal outcome among patients with COVID-19. Consecutive adult inpatients with SARS-CoV-2 infection and respiratory symptoms treated in three different COVID centres were enrolled, and they were tested for laboratory parameters within 48 h from admission. Three-hundred ninety patients were enrolled. Age, baseline CRP, and LDH were associated with a P/F ratio < 200 during hospitalization. Male gender and CRP > 60 mg/L were shown to be independently associated with ICU admission. Lymphocytes < 1000 cell/µL were associated with the worst P/F ratio. CRP > 60 mg/L predicted exitus. We subsequently devised an 11-points numeric ordinary scoring system based on age, sex, CRP, and LDH at admission (ASCL score). Patients with an ASCL score of 0 or 2 were shown to be protected against a P/F ratio < 200, while patients with an ASCL score of 6 to 8 were shown to be at risk for P/F ratio < 200. Patients with an ASCL score ≥ 7 had a significantly increased probability of death during hospitalization. In conclusion, patients with elevated CRP and LDH and an ASCL score > 6 at admission should be prioritized for careful respiratory function monitoring and early treatment to prevent a progression of the disease.

COVID-19 chest CT and laboratory features of B.1.617.2 (Delta variant) vs B.1.1.7 (Alpha variant) surge: a single center case-control study.

Purpose: To assess clinical, laboratory and radiological differences between Delta and Alpha SARS-CoV-2 variants. Materials and Methods: Twenty SARS-CoV-2 patients admitted from 30th of August to 30th of October 2021 (period with estimated highest prevalence of Delta variant circulation in Italy) were enrolled. Patients were matched in a 1:1 ratio with same gender and same age +/- 2 years controls admitted from 1st of September 2020 to 30th of January 2021 (predominant circulation of Alpha variant). Chest computed tomography (CT) were retrospectively evaluated. Main clinical parameters, radiological and laboratory findings were compared between two groups. Results: Patients with probable Delta variant had significantly higher CT severity scores, lower PaO2/FiO2 ratio and higher C-reactive protein and lactate dehydrogenase levels at admission. On multivariate analysis, probable Delta variant infection was associated with higher CT severity score. Ground glass opacities and crazy paving patterns were more frequently noticed than consolidation, with the latter being more frequent in Delta cohort, even though not significantly. According to prevalent imaging pattern, the consolidation one was significantly associated with pregnancy (p=0.008). Conclusions: Patients admitted during predominance of Delta variant circulation had a more severe lung involvement compared to patients in infected when Alpha variant was predominant. Despite imaging pattern seems to be not influenced by viral variant and other clinical variables, the consolidative pattern was observed more frequently in pregnancy.

mTOR Inhibitor Use Is Associated With a Favorable Outcome of COVID-19 in Patients of Kidney Transplant: Results of a Retrospective Study.

Introduction: In solid organ transplant recipients, COVID-19 is associated with a poor prognosis because of immunosuppression. Some studies suggest a potential therapeutic role of mammalian Target of Rapamycin (mTOR) inhibitors in SARS-CoV-2 infection. This study aimed to assess the impact of mTOR employment on the evolution and outcome of SARS-CoV-2 infection in solid organ transplant recipients. Methods: We enrolled kidney transplant patients attending the Azienda Ospedaliera Universitaria Federico II in Naples and followed up on these patients from March 2020 to June 2021. We evaluated the risk of acquiring the SARS-CoV-2 infection, the clinical presentation of the disease, and its outcome together with the type of immunosuppressive therapy. Finally, we assessed the impact of mTOR inhibitors on relevant clinical metrics of SARS-CoV-2 infection. Results: We enrolled 371 patients, of whom 56 (15.1%) contracted SARS-CoV-2 infection during the period of the study. There were no differences observed among the different immunosuppressive therapies concerning the risk of acquiring SARS-CoV-2 infection. In contrast, the type of immunosuppressive therapy had a significant impact on the outcome of the disease. In detail, patients who received mTOR inhibitors, as part of their immunosuppressive therapy, compared to other regimens had a lower chance of developing a moderate or severe form of the disease (OR = 0.8, 95, CI: (0.21-0.92), P = 0.041). Conclusion: In kidney transplant patients, the use of mTOR inhibitors as part of an immunosuppressive regimen is associated with a better prognosis in the case of COVID-19.

SARS-CoV-2 in Kidney Transplant Patients: A Real-Life Experience.

Background: The COVID-19 pandemic has significantly impacted the management of solid organ transplant recipients and on clinical evolution in post-transplantation. Little is known on the impact of SARS-CoV-2 infection in these patients. The severity and lethality of this disease in solid organ transplant patients are higher thanin the general population. This study aims to describe clinical characteristics of SARS-CoV-2 infection in solid organ transplant recipients followed in our center. Methods: In this observational study, we enrolled all kidney transplant recipientsattending the A.O.U. Federico II of Naples from March 2020 to January 2021. For each patient we evaluated the epidemiological and clinical characteristics as well as outcome. Results: We enrolled 369 kidney transplant patients (229, male, 62%). Of these, 51 (13.8%) acquired SARS-CoV-2 infection and 29 showed symptomatic disease. Of the 51 patients with the infection, 48 (94.11%) had at least one comorbidity and such comorbidities did not constitute a risk factor for a more severe disease. Hospitalization was necessary for 7 (13.7%) patients. Of these, 2 required low-flow oxygen supplementation, 3 non-invasive/high flow ventilation and 2 invasive ventilation. Finally, 2 patients died. Conclusions: Our study shows a lower mortality and hospitalization rate compared to figures available in the literature (4% vs. 13-30% and 14% vs. 32-100%, respectively). Furthermore, the comorbidities examined (hypertension, dyslipidemia, and diabetes) did not constitute a risk factor for a more severe disease condition in this patient category. Further studies with larger sample size are necessary to confirm these data.

Quantitative but not qualitative flavor recognition impairments in COVID-19 patients.

BACKGROUND: Smell and taste dysfunctions (STDs) are symptoms associated with COVID-19 syndrome, even if their incidence is still uncertain and variable. AIMS: In this study, the effects of SARS-CoV-2 infection on chemosensory function have been investigated using both a self-reporting questionnaire on smell and flavor perception, and a simplified flavor test. METHODS: A total of 111 subjects (19 hospitalized [HOS] and 37 home-isolated [HI] COVID-19 patients, and 55 healthy controls [CTRL]) were enrolled in the study. They received a self-evaluation questionnaire and a self-administered flavor test kit. The flavor test used consists in the self-administration of four solutions with a pure olfactory stimulus (coffee), a mixed olfactory-trigeminal stimulus (peppermint), and a complex chemical mixture (banana). RESULTS: After SARS-CoV-2 infection, HOS and HI patients reported similar prevalence of STDs, with a significant reduction of both smell and flavor self-estimated perception. The aromas of the flavor test were recognized by HI and HOS COVID-19 patients similarly to CTRL; however, the intensity of the perceived aromas was significantly lower in patients compared to controls. CONCLUSION: Data reported here suggests that a chemosensory impairment is present after SARS-CoV-2 infection, and the modified "flavor test" could be a novel self-administering objective screening test to assess STDs in COVID-19 patients. CLINICAL TRIAL REGISTRATION NO: NCT04840966; April 12, 2021, retrospectively registered.

Pneumocystis jirovecii Pneumonia in Non-HIV Patients Recovering from COVID-19: A Single-Center Experience.

OBJECTIVE: to describe a single-center experience of Pneumocystis jirovecii pneumonia (PJP) in non-HIV patients recovering from COVID-19. METHODS: We report the cases of five non-HIV patients with COVID-19 who also developed PJP at a University Hospital. RESULTS: With the exception of one subject, who experienced an atypical and prolonged course of COVID-19, all the patients developed PJP after the clinical resolution of COVID-19 pneumonia. All but one patient had no pre-existing immunosuppressive conditions or other risk factors for PJP development at COVID-19 diagnosis. Nonetheless, following the course of COVID-19 infection, all the patients fulfilled at least one host factor for PJP; indeed, all the patients had received at least 2 weeks of high-dose steroids and three out of five had a CD4+ cell count <200/mm3. CONCLUSIONS: The use of corticosteroids for COVID-19 respiratory impairment seems to be the most common risk factor for PJP, together with viral-induced and iatrogenic lymphopenia. The worsening in respiratory function and the characteristic radiological picture during or after COVID-19 pneumonia should raise the suspicion of PJP, even in immunocompetent patients. PJP primary chemoprophylaxis can be considered in selected high-risk COVID-19 patients, but further studies are needed.

Home Parenteral Nutrition in Patients with Intestinal Failure: Possible Undetected Complications.

BACKGROUND: Septic pulmonary embolism (SPE) may be a frequently undetected complication of central venous catheter (CVC)-related bloodstream infections (CRBSIs). MATERIALS AND METHODS: The incidence of SPE was evaluated in a cohort of non-oncological patients on home parenteral nutrition (HPN) who were hospitalized for a CRBSI from January 2013 to December 2017. The main clinical, microbiological, and radiological features and the therapeutic approach were also described. RESULTS: Twenty-three infections over 51,563 days of HPN therapy were observed, corresponding to an infection rate of 0.45/1000. In 10 out of the 23 cases (43.5%), pulmonary lesions compatible with SPE were identified. CONCLUSION: Our results demonstrated that a CRBSI can produce asymptomatic SPE with lung infiltrates in 43.5% of the cases, suggesting the need to check for secondary lung infections to choose the most appropriate antimicrobial therapy.

Central venous catheter related bloodstream infections in adult patients on home parenteral nutrition: Prevalence, predictive factors, therapeutic outcome.

BACKGROUND: The prevalence of central venous catheter (CVC)-related blood-stream infections (CRBSI), infecting agents and the effectiveness of antibiotic therapy were evaluated in 172 adult patients on Home Parenteral Nutrition (HPN) at the Clinical Nutrition Outpatient Unit of Federico II University Hospital in Naples, Italy. MATERIALS AND METHODS: The study population consisted of 127 oncological (74%) and 45 (26%) non-oncological patients, for a total of 53,818 (median 104; range 14-1080) CVC days. RESULTS: Ninety-four CRBSIs were diagnosed on 238 CVC (infection rate 1.74/1000 CVC days). Coagulase negative (CoNs) Staphylococci were the most frequently infecting agents (52.8% as single agent) with 17.1% Staphylococcus epidermidis infections. Eighty-three percent S. epidermidis were beta-lattamase producer (BLACT), 66.6% methicillin-resistant (MR) and 55.5% had a MIC for Vancomicin ≥1. Gram-negative bacteria represented 18.6% infections, fungi 7.1%, finally 15% infections were polymicrobial. Previous catheterizations and the presence of an enterocutaneous stoma were significantly related with a higher infection risk (p < 0.0001 in both cases). CONCLUSIONS: CRBSI and antibiotic resistance of infecting agents remain an important challenge in adult patients on HPN; an active research on strategies to counteract the phenomena is required.

Fecal microbiota transplantation for Clostridium difficile infection: back to the future.

INTRODUCTION: Clostridium difficile infection (CDI) is a leading cause of diarrhea in the industrialized world. The estimated costs of this infection are impressive: over 3.2 billion dollars annually in the US. The introduction of fecal microbiota transplantation (FMT) to clinical practice can be considered a Copernican Revolution. The rationale of this approach consists of correcting the imbalance of the organisms dwelling in the gut by reintroducing a normal flora. AREAS COVERED: This review focuses on the indication for FMT in CDI; it examines in-depth the most relevant aspects of the techniques used, and the safety and efficacy of this new 'old' therapy. EXPERT OPINION: Authoritative guidelines about the management of CDI strongly recommend FMT for multiple recurrent episodes of infection by C. difficile unresponsive to repeated antibiotic treatment. The cure rates are about 90%, with no serious adverse events having been reported. The main concerns are the long-term outcomes, lack of a standardized procedure for the delivery of donor material, and a cultural barrier to the transplantation of fecal microbiota. A promising solution to some of these problems could be the use of a more acceptable administration route of fecal material, namely, oral capsules.

A retrospective study on HIV and syphilis.

In the early 1990s a reduction in the rate of sexually transmitted infections (STIs) occurred, although recent years have seen an increase. The aim of this study was to examine epidemiological and clinical features of syphilis cases in patients with HIV infection. We reviewed the charts of HIV-infected patients referring to our centre in the period 2002-2011. Fifty of the 402 consecutive HIV-positive patients (12.4%) received a diagnosis of syphilis. An increasing trend in the number of syphilis cases was observed within the period of the study. Most patients with syphilis (64%) presented a latent syphilis of unknown duration. About half of these received a concomitant diagnosis of HIV infection. Men who have sex with men (MSM) were the largest group. In the years 2002-2011, the incidence of syphilis in HIV-infected patients increased in our centre, notably among MSM. There is an urgent need for campaigns aiming to prevent STIs.

Human platelet antigen-3 genotype predicts platelet count in patients with HCV infection.

BACKGROUND/AIM: A low platelet count is one of the most sensitive tests for cirrhosis detection in patients with hepatitis C virus (HCV) infection. We evaluated whether the human platelet antigen (HPA) genotype could predict platelet count in HCV-positive patients. MATERIALS AND METHODS: We genotyped the HPA 1, 2, 3, 5 and 15 polymorphisms in consecutive patients with HCV infection. RESULTS: Out of the 56 patients enrolled, 56.1% had liver cirrhosis. The mean platelet count was significantly lower in those with HPA1aa genotype than in those with HPA1ab/bb genotype. Platelet count did not differ among the other HPA polymorphisms. However, at logistic regression analysis, only the HPA3aa genotype and liver cirrhosis were independent predictors of a low platelet count. CONCLUSION: HPA3aa is an independent factor for a low platelet count in this cohort of patients with HCV chronic infection regardless of disease stage.
