Abstract
Introduction: Multidrug-resistant Pseudomonas aeruginosa isolates have multiple resistance mechanisms, and there are insufficient therapeutic options to target them. Ceftolozane-tazobactam is a novel antipseudomonal agent that contains a combination of an oxyimino-aminothiazolyl cephalosporin (ceftolozane) and a β-lactamase inhibitor (tazobactam). Methods: A single-center retrospective observational study between January 2017 and December 2018 for patients who had been diagnosed with carbapenem-resistant P aeruginosa infections and treated with ceftolozane-tazobactam for more than 72 hours. We assessed clinical success based on microbiological clearance as well as the clinical resolution of signs and symptoms of infection. Results: A total of 19 patients fit the inclusion criteria, with a median age was 57 years, and 53% were female. The types of infections were nosocomial pneumonia, acute bacterial skin, and skin structure infections; complicated intra-abdominal infections; and central line–associated bloodstream infections. All of the isolates were resistant to both meropenem and imipenem. The duration of therapy was variable (average of 14 days). At day 14 of starting ceftolozane-tazobactam, 18 of 19 patients had a resolution of signs and symptoms of the infection. Only 14 of 19 patients (74%) had proven microbiological eradication observed at the end of therapy. During therapy, there was no adverse event secondary to ceftolozane-tazobactam, and no Clostridium difficile infection was identified. The 30-day mortality rate was 21% (4/19). Conclusions: Multidrug-resistant P aeruginosa infection is associated with high mortality, which would potentially be improved using a new antibiotic such as ceftolozane-tazobactam. Studies are required to explain the role of combination therapy, define adequate dosing, and identify the proper duration of treatment.

Abstract
OBJECTIVE The bacille Calmette Guérin (BCG) vaccine is administered worldwide to prevent tuberculosis. Although, Post BCG vaccination complications like disseminated BCG infections are rare and immunocompromised children are at high risk of developing BCG-related complications including BCG-lymphadenitis and other disseminated diseases. PATIENTS AND METHODS This was a prospective study of children who developed disseminated BCG after vaccination who were admitted in three tertiary care hospital in Riyadh, Saudi Arabia, in the year 2015. The clinical presentation, microbiological/immunological evaluation and outcome will be discussed. RESULTS 12 cases (7 males and 5 females) of disseminated BCG infections after vaccination were documented with age ranges 3 and 32 months. Eight (66%) patients had interleukin IL-12 deficiency and 3 (25%) had severe combined immune deficiency (SCID) and 1 (8%) had Interferon gamma receptor II deficiency. 9 (75%) patients presented with generalized lymphadenopathy. Hepatosplenomegaly was present in 6 (50%) patients. 2 (16%) patients presented with a recurrent skin infection and persistent oral candidiasis in one patient and pneumonia in the other. Five (41%) families were from 1st degree consanguineous marriage. Tuberculosis (TB) culture and sensitivity were positive for Mycobacterium bovis from gastric aspirate (GA) in 4 patients and the lymph node in 9 patients and 1 patient had culture positive from both skin lesion and lymph nodes. Mycobacterium bovis PCR was positive in 4 patients. All patients received anti-tuberculosis therapy; all patients survived except one who died due to multi-organ failure. CONCLUSIONS These results indicate that the prevalence of disseminated BCG vaccine in immunocompromised Saudi children is significantly high. Since in our region we have a high consanguinity rate and a high number of primary immune deficiency disorder (PID), we believe that BCG vaccination should be postponed till a child reaches one-year-old and appropriate tests exclude the diagnosis of primary immunodeficiency diseases.

The prevalence of community-associated methicillin-resistant Staphylococcus aureus among outpatient children in a tertiary hospital: A prospective observational study in Riyadh, Saudi Arabia. Int J Pediatr Adolesc Med 2015; 2:136-140.

Abstract
Background and objectives The emergence of methicillin-resistant Staphylococcus aureus (MRSA) infections among previously healthy persons in community settings, without exposure to health care facilities, has been noted recently. Colonization rates of community-associated MRSA (CA-MRSA) have been reported to range from 0 to 9.2 percent. The nose and open skin areas are considered the most important sites for colonization. The aim of our study was to assess the prevalence and to describe the antibiotic susceptibility pattern of CA-MRSA among outpatient children. Patients and methods We prospectively screened every third consecutive child presenting to our pediatric emergency department of King Saud Medical City, a 275 bed tertiary care teaching hospital in Riyadh, Saudi Arabia, from March through July 2015. Results We analyzed a total of 830 screening results (n = 478 males, 57.6%). Most of the screened patients were from Riyadh (n = 824, 99.3%). A total of 164 (19.8%) were found to be colonized with S. aureus, and of these 38 (4.6%) with MRSA. Thus, the MRSA rate amongst all S. aureus carriers was 23.2%. All MRSA were susceptible to vancomycin, (94.7%) were susceptible to linezolid, (65.8%) to clindamycin, and (89.5%) to trimethoprim/sulfamethoxazole. Conclusion The rate of MRSA carriage among children in Riyadh province was within the range reported internationally. As the MRSA rate among S. aureus infected children was 23.2%, empirical MRSA coverage should be considered in children with suspected S. aureus infections.
