Use of bedaquiline in spinal osteomyelitis and soft tissue abscess caused by multidrug-resistant Mycobacterium tuberculosis: A case report.

INTRODUCTION: Spinal Tuberculosis (STB) represents between 1% and 2% of total tuberculosis cases. STB management remains challenging; the first-line approach consists of medical treatment, while surgery is reserved for patients with complications. No data regarding STB treatment with bedaquiline-containing regimens are available in the literature. CASE DESCRIPTION: Herein, we report the case of a 21-year-old man from Côte d'Ivoire with a multidrug resistance STB with subcutaneous abscess. After approval of the hospital off-label drug committee, we started bedaquiline 400 mg daily for two weeks, followed by 200 mg three times per week, for 22 weeks, associated with linezolid 600 mg daily, rifabutin 450 mg daily, and amikacin 750 mg daily (interrupted after eight weeks). During treatment, we performed a weekly EKG. No QT prolongation was shown, but inverted T waves appeared, requiring several cardiological consultations and cardiac MRI, but no cardiac dysfunction was found. After 24 weeks, bedaquiline was replaced with moxifloxacin 400 mg daily. The patient continued treatment for another year. We performed another computer tomography at the end of treatment, confirming the cure. DISCUSSION: A salvage regimen containing bedaquiline proved effective in treating multidrug-resistance tuberculosis spinal infection without causing severe adverse effects. However, further studies are needed to evaluate better bedaquiline bone penetration and the correct duration of treatment with bedaquiline in MDR spinal tuberculosis.

Travel-Related Typhoid Fever: Narrative Review of the Scientific Literature.

Enteric fever is a foodborne infectious disease caused by Salmonella enterica serotypes Typhi and Paratyphi A, B and C. The high incidence in low income countries can increase the risk of disease in travelers coming from high income countries. Pre-travel health advice on hygiene and sanitation practices and vaccines can significantly reduce the risk of acquiring infections. Although the majority of the cases are self-limiting, life-threatening complications can occur. Delayed diagnosis and cases of infections caused by multi-drug resistant strains can complicate the clinical management and affect the prognosis. More international efforts are needed to reduce the burden of disease in low income countries, indirectly reducing the risk of travelers in endemic settings. Surveillance activities can help monitor the epidemiology of cases caused by drug-susceptible and resistant strains.

Ebola virus disease: Case management in the Institute of Infectious Diseases, University Hospital of Sassari, Sardinia, Italy.

Since the onset of the worst epidemic of Ebola virus disease in December 2013, 28,637 cases were reported as confirmed, probable, or suspected. Since the week of 3 January 2016, no more cases have been reported. The total number of deaths have amounted to 11,315 (39.5%). In developed countries, seven cases have been diagnosed: four in the United States, one in Spain, one in the United Kingdom, and one in Italy. On 20 July 2015, Italy was declared Ebola-free. On 9 May 2015, an Italian health worker came back to Italy after a long stay in Sierra Leone working for a non-governmental organization. Forty-eight hours after his arrival, he noticed headache, weakness, muscle pains, and slight fever. The following day, he was safely transported to the Infectious Diseases Unit of University Hospital of Sassari. The patient was hospitalized for 19 hours until an Italian Air Force medical division transferred him to Rome, to the Lazzaro Spallanzani Institute. Nineteen people who had contacts with the patient were monitored daily for 21 days by the Public Health Office of Sassari and none presented any symptoms. So far, neither vaccine nor treatment is available to be proposed on an international scale. Ebola is considered a re-emerging infectious disease which, unlike in the past, has been a worldwide emergency. This case study aimed to establish a discussion about the operative and logistic difficulties to be faced and about the discrepancy arising when protocols clash with the reality of facts.

Helicobacter pylori active infection in patients with acute coronary heart disease.

OBJECTIVES: To evaluate the possible role of the active Helicobacter pylori infection as a trigger factor in acute coronary heart disease (CHD). METHODS: Forty patients with acute coronary syndromes, 40 patients with infections other than H. pylori (control group A) and 40 healthy subjects (control group B), pair matched for age, sex and CHD risk factors were studied. In each patient and control subject the presence of H. pylori stool antigen (HpsA) and serum anti-CagA were tested. RESULTS: Twenty-eight of patients with CHD resulted positive for HpSA compared to 14 patients of control group A and 16 subjects of group B (p=0.00095). No significant difference was found in the anti-CagA positivity among patients with CHD and control groups. Concomitant positivity for anti-CagA and HpSA was found in 13 patients with CHD, four controls of group A and five controls of group B (p=0.017) CONCLUSIONS: Our findings revealed a higher rate of HpSA positivity and a significantly higher association between HpSA and anti-CagA positivity in patients with acute CHD compared to control groups. These data suggest that active H. pylori infection may play a role as a trigger factor in acute cardiovascular events.
