Ceftazidime-avibactam use for klebsiella pneumoniae carbapenemase-producing k. pneumoniae infections: A retrospective observational multicenter study

2021

Abstract Background A growing body of observational evidence supports the value of ceftazidime-avibactam (CAZ-AVI) in managing infections caused by carbapenem-resistant Enterobacteriaceae. Methods We retrospectively analyzed observational data on use and outcomes of CAZ-AVI therapy for infections caused by Klebsiella pneumoniae carbapenemase–producing K. pneumoniae (KPC-Kp) strains. Multivariate regression analysis was used to identify variables independently associated with 30-day mortality. Results were adjusted for propensity score for receipt of CAZ-AVI combination regimens versus CAZ-AVI monotherapy. Results The cohort comprised 577 adults with bloodstream infections (n = 391) or nonba…

Oral leishmaniasis in an HIV-infected patient.

2000

As in most countries in the Mediterranean basin, leishmaniasis is endemic in Italy, where it has visceral (VL) and cutaneous (CL) forms caused by viscerotropic and dermotropic strains of Leishmania infantum, respectively. With the spread of the acquired immunodeficiency syndrome (AIDS) epidemic, the number of coinfections with Leishmania and human immunodeficiency virus (HIV) is increasing. Between 35% and 50% of the adult VL cases diagnosed annually in Sicily from 1991 to 1995 were related to HIV [1]; although cases of coinfection have been reported in 28 countries worldwide, the majority of these cases (1440 from 1990 to 1998) have been notified in four countries (Spain, Italy, France, Po…

Leishmaniasis among organ transplant recipients.

2008

Leishmaniasis is a rarely reported disease among transplant recipients; however, the number of published cases has quadrupled since the beginning of the 1990s. Most cases have been observed in patients living in countries of the Mediterranean basin. Leishmaniasis is most commonly associated with kidney transplantation (77%), and cases are also recorded among patients undergoing liver, heart, lung, pancreas, and bone marrow transplantation. Visceral leishmaniasis (VL) is the most frequently observed clinical presentation, followed by mucosal leishmaniasis and more rarely cutaneous leishmaniasis. Transplant recipients with VL develop the classic clinical form of the disease, which is a febril…

Treatment of human brucellosis with rifampin plus minocycline

2003

In order to evaluate the efficacy and tolerability of a high intravenous dose of rifampin plus oral minocycline (administered daily for 3 weeks) for the treatment of acute brucellosis, we retrospectively reviewed the outcome of 239 consecutive patients (135 adults and 104 children) diagnosed and treated over a 17-year period in Italy. The combination used resulted in 100% response and a relapse rate lower than 2%. Fifty-two (30 adults and 22 children) (29.8%) complained of mild adverse effects including an increase in aspartate aminotransferase (>250 IU) observed in 12 cases and considered related to rifampin and in 11 cases a reversible hyperpigmentation of the tongue attributed to minocyc…

Subacute Malaria Due toPlasmodium falciparumand the Role of Polymerase Chain Reaction

2001

Clinical use of polymerase chain reaction performed on peripheral blood and bone marrow samples for the diagnosis and monitoring of visceral leishman…

2007

Background To overcome some of the limitations of conventional microbiologic techniques, polymerase chain reaction (PCR)-based assays are proposed as useful tools for the diagnosis of visceral leishmaniasis. Patients and methods A comparative study using conventional microbiologic techniques (i.e., serologic testing, microscopic examination, and culture) and a Leishmania species-specific PCR assay, using peripheral blood and bone marrow aspirate samples as templates, was conducted during an 8-year period. The study cohort consisted of 594 Italian immunocompetent (adult and pediatric) and immunocompromised (adult) patients experiencing febrile syndromes associated with hematologic alteration…

A 6 day course of liposomal amphotericin B in the treatment of infantile visceral leishmaniasis: the Italian experience

2004

Objectives To evaluate in a retrospective analysis the efficacy and safety of a 6 day course of liposomal amphotericin B (L-AmB) in infantile cases of Mediterranean visceral leishmaniasis (VL) diagnosed over a 10 year period in Italy. Patients and methods Patients included were diagnosed as having VL consecutively admitted from December 1992 to December 2001 at four main referral children's hospitals in Italy and treated with six intravenous doses of 3 mg/kg L-AmB given on days 1-5 and 10 (a total dose of 18 mg/kg). Demographic data, nutritional status, underlying diseases, clinical and laboratory findings, and therapy outcome were considered. Results A total of 164 HIV-negative children (m…

Intestinal tuberculosis as a cause of chronic diarrhoea among patients with human immunodeficiency virus infection: report of two cases.

2001

In Western countries human immunodeficiency virus infection is considered the main risk factor of tuberculous disease, its incidence being 500 times higher in HIV-infected patients than in the general population. Despite the disease frequently present in these patients with extraintestinal manifestations, intestinal localization is rarely observed and often as a consequence of complications such as acute gastrointestinal bleeding or perforation. The diagnosis of intestinal tuberculosis is difficult and is often delayed due to the lack of specific signs and symptoms as well as the low sensitivity of routine methods. A review of the literature is made and personal experience in the diagnosis …

Pediatric visceral leishmaniasis in Western Sicily, Italy: a retrospective analysis of 111 cases

2002

The clinical and epidemiological characteristics of 111 consecutive cases of visceral leishmaniasis identified from 1980 to 2000 in a Sicilian pediatric hospital were analyzed retrospectively. The mean age of the patients was 1.7 years. All children were HIV negative, but 15% were severely malnourished. Fever and splenomegaly were present in all cases and hepatomegaly in 101 (90.1%) cases. Thrombocytopenia and anemia were both observed in 78 (70.2%) cases and leukopenia in 47 (42.3%) cases. A bone marrow aspirate was obtained in all cases; Leishmania amastigotes were detected in 89 (80.2%) cases. Initial treatment consisted of meglumine antimoniate in 99 (89.2%) patients and amphotericin B …

Polymerase chain reaction in the diagnosis and prognosis of Mediterranean visceral leishmaniasis in immunocompetent children.

2002

Objective. To assess the usefulness of a polymerase chain reaction (PCR) assay amplifying the small subunit rRNA coding region of Leishmania species performed on peripheral blood (PB) and bone marrow (BM) aspirates for the diagnosis and follow-up of visceral leishmaniasis (VL) in children living in the Mediterranean basin. Design. A prospective study was conducted on children consecutively hospitalized over a 1-year period at our Infectious Diseases Department in Sicily (Italy) presenting with fever, hepatosplenomegaly, and/or pancytopenia and a positive Leishmania serology (≥1:40). Results. Among the 14 patients hospitalized with signs and symptoms suggestive of the disease and a positive …

Role of PCR in Diagnosis and Prognosis of Visceral Leishmaniasis in Patients Coinfected with Human Immunodeficiency Virus Type 1

2001

ABSTRACT A group of 76 consecutive human immunodeficiency virus (HIV)-positive patients with fever of unknown origin ( n = 52) or fever associated with pulmonary diseases was evaluated in order to assess the usefulness of PCR with peripheral blood in the diagnosis and follow-up of visceral leishmaniasis. We identified 10 cases of visceral leishmaniasis among the 52 patients with fever of unknown origin. At the time of diagnosis, all were parasitemic by PCR with peripheral blood. During follow-up, a progressive decline in parasitemia was observed under therapy, and all patients became PCR negative after a median of 5 weeks (range, 6 to 21 weeks). However, in eight of nine patients monitored …

Clarithromycin Versus Azithromycin in the Treatment of Mediterranean Spotted Fever in Children: A Randomized Controlled Trial

2002

We conducted an open-label randomized controlled trial to compare the efficacy and safety of clarithromycin (15/mg/kg/day in 2 divided doses for 7 days) with those of azithromycin (10 mg/kg/day in 1 dose for 3 days) in the treatment of children with Mediterranean spotted fever. Until now, there has not been a gold-standard therapy for this rickettsial disease in children. Eighty-seven children were randomized to receive 1 of the 2 drugs. The mean time to defervescence (+/- standard deviation) was 46.2+/-36.4 h in the clarithromycin group and 39.3+/-31.3 h in the azithromycin group. These differences were not statistically significant and both drugs were equally well-tolerated. Clarithromyci…
