Patients with Primary Immunodeficiencies in Pediatric Intensive Care Unit: Outcomes and Mortality-Related Risk Factors

Purposes

The aims of this study were to review the frequency, characteristics, and the clinical course of primary immunodeficiency (PID) patients admitted to pediatric intensive care unit (PICU) and attempt to identify factors related with mortality that might predict a poor outcome.

Methods

We performed a retrospective review of children with PID aged 1 month to 18 years and admitted to PICU from January 2002 to January 2012 in our tertiary teaching children’s hospital.

Results

There were a total of 51 patients accounting for 71 admissions to the PICU. The most common diagnosis was severe combined immunodeficiency. Respiratory problems were the leading cause for admission. A total of 20 patients received hematopoietic stem cell transplantation. Immune reconstitution was achieved in 9 (45 %) patients and eight of them did survive. In all 56 % of all admission episodes resulted in survival. Risk factors for mortality included requirement of mechanical ventilation (P?<?.001), number of organ system failure (P?=?.013), need for renal replacement therapy (P?<?.001), use of inotropes (P?<?.001), higher Pediatric Logistic Organ Dysfunction (PELOD) score (P?=?.005), and length of PICU stay (P?<?.001).

Conclusions

This is the first study regarding the outcome and mortality-related risk factors for PID patients requiring PICU admission. We suggest that PICU management is as important as early diagnosis and treatment for these patients. Prediction of those at risk for poorer outcome might be beneficial for accurate intensive care management and survival.     

Assessment of Neuropsychological Late Effects in Survivors of Childhood Leukemia

The neurologic dysfunctions caused by treatment may affect health and quality of life in survivors of childhood leukemia. The objective of this study was to identify the neuropsychological late effects of leukemia treatment to provide an assessment about the degree and incidence of these late effects. Neurological and ophtalmological examination, cranial magnetic resonance imaging (MRI), auditory and neurocognitive tests, and questionnaires of quality of life were performed to 44 acute leukemia survivors at least 5 years after diagnosis. Median time since completion of chemotherapy was 7.5 years (2–18) and median age at the time of the study was 16.4 years (8–31). At least one or more late effects detected by physical examination (PE), neurological tests, or neurocognitive tests encountered in 80% of the patients, and 64% of the patients specified at least one complaint in the quality of life questionnaire. MRI revealed pathological findings in 18% and electroencephalogram (EEG) abnormalities were present in 9% of the patients. Evaluation of total intelligence scores revealed that 30% of patients’ IQ scores were <80 and 70% of the patients’ scores demonstrated neurocognitive dysfunctions. The patients >6 years at the time of diagnosis were found to have more psychological problems and higher rates of smoking and alcohol consumption. The most frequent complaint was headache and the most common problem in school was denoted as difficulty in concentration. Our study demonstrated that most of the survivors of childhood leukemia are at risk of developing neuropsycological late effects.     

Nasopharyngeal carriage of Streptococcus pneumoniae in healthy Turkish children after the addition of PCV7 to the national vaccine schedule

The aim of this study was to determine serotype distribution and investigate antimicrobial resistance patterns of Streptococcus pneumoniae in healthy Turkish children in the era of community-wide pneumococcal conjugate vaccine (PCV7). The study was conducted on 1,101 healthy children less than 18 years of age. Specimens were collected with nasopharyngeal swabs between April 2011 and June 2011. Penicillin and ceftriaxone susceptibilities were determined by E-test according to the 2008 Clinical Laboratory Standards Institute, and serotypes of the isolates were determined by Quellung reaction. The nasopharyngeal pneumococcal carriage rate was 21.9 % (241/1,101). Using the meningitis criteria of minimum inhibitory concentration values, 73 % of the isolates were resistant to penicillin and 47.7 % of them were resistant to ceftriaxone. Half of all pneumococcal isolates were serotyped as 19F (15.2 %), 6A (15.2 %), 23F (10.3 %), and 6B (9.3 %) and surprisingly, no serotype 19A was isolated. Serotype coverage rates of PCV7 and non-PCV7 were 46.2 and 53.8 %, respectively. The most common penicillin- and ceftriaxone-resistant serotypes were 6A, 6B, 14, 19F, and 23F. Penicillin- and ceftriaxone-resistant isolates were more prevalent in serotypes covered by PCV7 than the non-PCV7 serotypes. Conclusion: After the community-wide PCV7 vaccination, more non-PCV7 serotypes were isolated from the carriers compared to the time before PCV7 was used especially the serotype 6A, and the antimicrobial resistance of pneumococci was significantly increased.
