Prevalence, Outcome, and Prevention of Congenital Cytomegalovirus Infection in Neonates Born to Women With Preconception Immunity (CHILd Study).

BACKGROUND: Human cytomegalovirus (HCMV) is the leading infectious cause of congenital disabilities. We designed a prospective study to investigate the rate, outcome, and risk factors of congenital CMV (cCMV) infection in neonates born to immune women, and the potential need and effectiveness of hygiene recommendations in this population. METHODS: The study was composed of 2 sequential parts: an epidemiology (part 1) and a prevention (part 2) study. Performance of part 2 depended upon a cCMV rate >0.4%. Women enrolled in part 1 did not receive hygiene recommendations. Newborns were screened by HCMV DNA testing in saliva and cCMV was confirmed by urine testing. RESULTS: Saliva swabs were positive for HCMV DNA in 45/9661 newborns and cCMV was confirmed in 18 cases. The rate of cCMV was .19% (95% confidence interval [CI]: .11-.29%), and 3 out of 18 infants with cCMV had symptoms of CMV at birth. Age, nationality, occupation, and contact with children were similar between mothers of infected and noninfected newborns. Twin pregnancy (odds ratio [OR]: 7.2; 95% CI: 1.7-32.2; P = .037) and maternal medical conditions (OR: 3.9; 95% CI: 1.5-10.1; P = .003) appeared associated with cCMV. Given the rate of cCMV was lower than expected, the prevention part of the study was cancelled. CONCLUSIONS: Newborns from women with preconception immunity have a low rate of cCMV, which appears to be mostly due to reactivation of the latent virus. Therefore, serological screening in childbearing age would be pivotal to identify HCMV-seropositive women, whose newborns have a low risk of cCMV.

Fifteen-Year Surveillance of LTR Receiving Pre-Emptive Therapy for CMV Infection: Prevention of CMV Disease and Incidence of CLAD.

The efficacy of pre-emptive therapy in the prevention of cytomegalovirus (CMV) disease and the potential association of CMV infection with the occurrence of chronic lung allograft dysfunction (CLAD) was evaluated in 129 lung transplant recipients receiving pre-emptive therapy based on pp65-antigenemia or CMV-DNA in the blood and in the bronchoalveolar lavage. Seventy-one (55%) patients received pre-emptive ganciclovir/valganciclovir (GCV/VGCV) for CMV infection for a median of 28 (9-191) days. Possible CMV disease occurred in six (5%) patients and was healed after the GCV/VGCV therapy. The cumulative incidence of CLAD was 38% and 54% at 5 and 10 years. Acute rejection and CMV load in the blood (but not in the lung) were independent predictors of the occurrence of CLAD. Pre-emptive therapy is highly effective in preventing CMV disease in lung recipients and does not induce a superior incidence of CLAD compared to what reported for other cohorts of patients who received an extended antiviral prophylaxis.

Human Cytomegalovirus-Specific T-Cell Reconstitution and Late-Onset Cytomegalovirus Infection in Hematopoietic Stem Cell Transplantation Recipients following Letermovir Prophylaxis.

Letermovir (LTV), recently approved for the prophylaxis of human cytomegalovirus (HCMV) reactivation after hematopoietic stem cell transplantation (HSCT), has been shown to decrease the rate of infection in the first months post-transplantation. The aim of this study was to evaluate the impact of LTV prophylaxis on immune reconstitution and late-onset infection. We studied HCMV infection and HCMV-specific T cell reconstitution in 2 matched groups of HSCT recipients, those treated with LTV prophylaxis (n = 30; LTV group) and those receiving preemptive therapy (n = 31; PET group). We analyzed the rates of graft-versus-host disease (GVHD), neutropenia, baseline disease recurrence, and overall survival in the 2 groups. Clinically significant infections necessitating preemptive therapy showed a similar rate in the 2 groups (PET: 21 of 31 [68%]; LTV: 17 of 30 [57%]; P = .434) but occurred significantly later (after prophylaxis discontinuation) in the LTV group. There was no between-group difference in peak HCMV DNAemia level (P = .232). HCMV-specific T cell recovery was delayed by approximately 100 days in the LTV group. HCMV-specific CD4 and CD8 T cell counts were significantly lower in the LTV group at days 120 to 360 and days 90 to 120, respectively. A lower rate of chronic GVHD (P = .024) was seen in the LTV group. Time to engraftment, rate of disease relapse, and 1-year survival were not different between the 2 groups, whereas trends toward a lower rate of neutropenia (P = .124) and a higher rate of acute GVHD grade III-IV (P = .103) were observed in the LTV group. Because LTV prophylaxis delays HCMV infection and HCMV-specific immune reconstitution, immunologic and virologic monitoring should be implemented after discontinuation of prophylaxis. The potential effect of LTV prophylaxis in reducing chronic GVHD should be evaluated in prospective studies.

Anti-epidermal growth factor receptor skin toxicity: a matter of topical hydration.

Skin toxicity is a frequent complication of anti-epidermal growth factor receptor therapy, which can be an obstacle in maintaining the dose intensity and may negatively impact on the clinical outcome of cancer patients. Skin lesions depend on the disruption of the keratinocyte development pathways and no treatment is clearly effective in resolving the cutaneous alterations frequently found during anti-epidermal growth factor receptor therapy. Among systemic treatments, oral tetracycline proved to be useful in preventing skin manifestations. We describe the case of a patient affected by metastatic colorectal cancer, for whom a combination of chemotherapy and cetuximab was used as second-line treatment. The patient developed a symptomatic papulopustular skin rash that disappeared completely after a twice-daily application of a hydrating and moisturizing cream, mainly consisting of a mixture of paraffin, silicone compounds, and macrogol. The marked cutaneous amelioration allowed the patient to continue cetuximab without any further symptoms and was associated with a partial radiological response.

Multimodality treatment of osteosarcoma of the jaw: a single institution experience.

Osteosarcomas of the jaws are rare mesenchymal tumors frequently diagnosed in the fourth decade of life which account for 6 % of all osteosarcomas. This study evaluated the efficacy on the patients outcome of multimodality treatment consisting of surgery, chemotherapy and radiotherapy. The records of 22 patients affected by jaw osteosarcoma treated with a combination of surgery, poly-chemotherapy and adjuvant radiotherapy in selected cases were reviewed. Response rate, progression-free survival and overall survival were evaluated. Neoadjuvant chemotherapy resulted in an overall response rate of 83.3 %, necrosis of grade I or II was obtained, respectively, in 44.4 and 55.6 % of the patients, and surgery was radical in all patients. At a median follow-up of 60 months, the 5-year progression-free survival and overall survival were 73.5 and 77.4 %, respectively. These outcome parameters significantly correlated with age at diagnosis and grade of chemotherapy-induced necrosis. A complex multimodality approach including chemotherapy and radiotherapy, along with radical surgery, can maximize the outcome of patients affected by osteosarcoma of the jaws.
