Bacterial meningitis in patients with sickle cell anemia in Salvador, Bahia, Brazil: a report on ten cases

Seizures risk factors in sickle cell disease. The cooperative study of sickle cell disease

INTRODUCTION

Although evidence suggests that neurological complications, including seizures and epilepsy, are more common among sickle cell disease (SCD) patients, few studies have assessed the risk factors of developing seizures among SCD patients METHODS: We used a nested case-control study design to compare pediatric and adult SCD patients who experienced seizures with patients who did not experience any seizure regarding clinical and laboratory parameters. We conducted a secondary analysis using the data from the Cooperative Study of Sickle Cell Disease in this study RESULTS: There were 153 out of 2804 (5.5%) pediatric patients who had seizures with a median age of 8.5 (Interquartile range [IQR] = 10.1) years at first seizure and 115 out of 1281 (9.0%) adult patients who had seizures with a median age of 28.0 (IQR = 10.6) years at first seizure. Cerebrovascular accident ([CVA], OR = 5.7, 95% CI = 2.9-11.0), meningitis (OR = 3.6, 95% CI = 1.8-7.2), and eye disease (OR = 3.4, 95% CI = 1.5-8.0) were associated with increased risk of developing seizures among pediatric patients. While CVA (OR = 7.5, 95% CI = 3.5-16.0), meningitis (OR = 5.6, 95% CI = 1.5-20.0), nephrotic syndrome (OR = 3.0, 95% CI = 1.2-7.9), spleen sequestration (OR = 2.7, 95% CI = 1.1-6.3), and pneumonia (OR = 2.1, 95% CI = 1.0-4.4) were associated with increased risk of developing seizures among adult patients CONCLUSION: These findings suggest the need for treatment optimization and regular neurological follow up for SCD patients with these identified risk factors to prevent the development of seizures.

Prevalence of Serious Bacterial Infections in Children with Sickle Cell Disease at King Abdulaziz Hospital, Al Ahsa

Objective

The main aim was to report the prevalence and severity of serious bacterial infections (SBI) in children with sickle cell disease at King Abdulaziz Hospital (KAH), Al Ahsa, Saudi Arabia, to aid in determining whether outpatient management of such cases is appropriate.

Methods

We conducted a retrospective chart review of febrile children less than 14 years of age admitted with sickle cell disease 2005 through 2015.

Results

During 320 admissions, 25 children had SBIs (8%) including pneumonia (n=11), osteomyelitis (n=8), bacteremia (n=3, all with Salmonella species) and UTI (n=3). All recovered uneventfully.

Conclusion

It appears that in the current era, less than 10% of febrile children with sickle cell disease in our center are diagnosed with an SBI. Over 11 years, there were no sequelae or deaths from SBI. Given these excellent outcomes, outpatient ceftriaxone should be considered for febrile well-appearing children with sickle cell disease if they have no apparent source and parents are judged to be reliable.
