Antistreptococcal response is exaggerated in children with familial Mediterranean fever.

Familial Mediterranean fever (FMF) is an autosomal recessive disorder. Although the pathogenesis of the disease is not yet completely understood, enhanced acute-phase responsiveness is considered to be one of the most important mechanisms. The presence of high levels of antistreptolysin O (ASO) antibodies and streptococcus-associated diseases, such as acute poststreptococcal glomerulonephritis (AGN) and acute rheumatic fever (ARF), has been reported in patients with FMF. In order to better understand the effect of FMF on antistreptococcal antibody response, we measured ASO and antideoxyribonuclease B (anti-DNAse B) levels in patients with FMF and compared them with those in healthy controls. The study consisted of two parts. In the first step, antistreptococcal antibody levels were analysed in 44 patients with FMF and 165 healthy children who had no history or clinical evidence of upper respiratory tract infection (URTI) for the last 4 months. In the second step, antistreptococcal antibody levels were measured in 15 patients with FMF and 22 healthy controls in response to documented group A beta-haemolytic streptococcal pharyngitis. In the first part of the study, ASO and anti-DNAse B levels in patients with FMF were found to be significantly higher than those in healthy controls (P<0.001). In the second part, ASO and anti-DNAse B titres were found to be significantly higher in patients with FMF than in controls (P<0.001 and <0.05, respectively) 4 weeks after a positive throat culture. We concluded that patients with FMF have an exaggerated response to streptococcal antigens and might be prone to poststreptococcal non-suppurative complications, such as ARF.

The value of the levels of acute phase reactants for the prediction of familial Mediterranean fever associated amyloidosis: a case control study.

In order to determine the role of levels of acute phase proteins (APPs) for the development of amyloidosis in familial Mediterranean fever (FMF) patients, the levels of serum amyloid A (SAA), C reactive protein (CRP), fibrinogen and erythrocyte sedimentation rate were measured in paired sera of 36 FMF patients during and in between acute attacks, 39 of their healthy parents (obligate heterozgotes), and 15 patients with FMF associated amyloidosis. To compare the levels of APPs, 39 patients with chronic infections or inflammatory diseases who may develop secondary amyloidosis, 20 patients with acute infections who are known to have elevated acute phase response but will never develop amyloidosis and 19 healthy controls were included. The median levels of all APPs are increased in the patients with FMF during attacks and a significant decrease was observed after the attack was over. The level of SAA was above reference range in all FMF patients during the attack free period and the level of at least one other APP was also above normal in 64% of the patients. Both CRP and SAA levels were found to be higher in obligate heterozygotes compared to controls. The levels of SAA in patients with FMF during the attack-free period, obligate heterozygotes and patients with FMF-amyloidosis were found to be similar. The levels in each group were found to be higher than SAA levels found in healthy controls yet lower than the levels measured in the patients with acute infections and patients with chronic inflammation or chronic infections. In conclusion, our results show that SAA level reflects subclinical inflammation with high sensitivity but its value for the prediction of amyloid formation process seems to be low.

Disseminated pyomyositis with high creatine phosphokinase levels.

Pyomyositis is a rare purulent infection of skeletal muscle caused predominantly by Staphylococcus aureus. We report a patient who presented with high fever, widespread muscle pain and high creatine phosphokinase levels. He also developed multiple muscle and lung abscesses associated with a S. aureus septicaemia.

Antibody response to measles vaccination in Turkish children.

In recent years, there has been a remarkable increase in measles cases among preschool and secondary school children in Turkey, as in many other countries. The seroconversion and coverage rates of measles vaccine should therefore be evaluated in order to obtain data that could be used to determine the vaccination policy for Turkey. Measles immunity status was studied by an enzyme-linked immunosorbent (ELISA) test determining the anti-measles IgG antibody levels. Measles specific IgG antibodies were found to be positive in 77.88% of the entire study group of 800 children aged 11 months to 12 years, while 21.25% had negative sera. Seven (0.87%) subjects had borderline results. The results of this study indicate the need to administer a second dose of measles vaccine, preferably at 18 months of age concomitant with other vaccines. This vaccination policy, together with an increase in the extent of immunization coverage, may help to achieve the World Health Organization's (WHO) target of the complete eradication of measles.

Campylobacter jejuni gastroenteritis in Turkish children.

Four hundred children between the ages of 1 month and 14 years with the complaint of diarrhea were studied to assess Campylobacter jejuni isolation rates in childhood acute gastroenteritis in Turkey and to clarify clinical presentations of C. jejuni enteritis. C. jejuni was found to be the second most common isolate with a rate of 8.3%, the first being Shigella strains. The highest isolation rate was in the 6 to 14-year age range at 12%. The most frequent symptoms in patients with C. jejuni enteritis were abdominal pain (51.5%), vomiting (36.4%) and fever (30.3%). Stool examination revealed bloody mucous stool in 51.5% of the patients, and erythrocytes and/or leucocytes were detected in 42.4%. Only 12.1% of the patients with C. jejuni enteritis were hospitalized in this study.

Investigation of risk factors for penicillin-resistant Streptococcus pneumoniae carriage in Turkish children.

BACKGROUND: Nasopharyngeal colonization plays an important role for infections caused by Streptococcus pneumoniae. Emergence of penicillin resistance in this organism has made it difficult to treat pneumococcal infections. The objectives of this study were to investigate the risk factors for nasopharyngeal colonization with S. pneumonia and for nasopharyngeal colonization with penicillin-resistant S. pneumoniae. METHODS: Three hundred children with or without evidence of infection were investigated for various risk factors. Streptococcus pneumoniae isolated from children's nasopharyngeal swabs were examined for penicillin susceptibility. RESULTS: Day-care attendance (odds ratio OR=2.82, P=0.003) and upper respiratory tract infection within the last month (OR=1.83, P=0.02), have been determined to be risk factors for S. pneumoniae carriage. The use of antibiotics within the last 3 months (OR=81.07, P<0.001), the presence of more than five people living in the house of the child (OR=6.63, P=0.03), and having a sibling under 5-years-old (OR=4.60, P=0.03) have been determined to be risk factors for penicillin-resistant S. pneumoniae carriage. CONCLUSION: Some children are inevitably exposed to and colonized with penicillin susceptible or resistant S. pneumoniae. Changes in day-care organizations, better living conditions, and restriction of antibiotic use seems to be useful precautions to prevent the emerging and colonization with penicillin-susceptible or -resistant S. pneumoniae.

Nasopharyngeal colonization with penicillin-resistant Streptococcus pneumoniae in Turkish children.

BACKGROUND: Streptococcus pneumoniae is one of the major infectious agents observed in children. In spite of the fact that penicillin is preferred in the treatment of infections caused by S. pneumoniae, there has been a world-wide increase in the frequency of penicillin-resistant S. pneumoniae. METHODS: One hundred and fifty sick children with a clinical diagnosis of pneumonia, meningitis, acute otitis media, acute sinusitis and septicemia or bacteremia, and 150 healthy children without any infection were examined. Streptococcus pneumoniae, which were isolated from the nasopharynx, were analyzed with respect to penicillin susceptibility using the agar dilution method. RESULTS: The S. pneumoniae carriage rate was observed to be 43.3% in the group of sick children and 30.0% in the control group (P < 0.05). The penicillin resistance of S. pneumoniae isolated from the nasopharynx was determined to be 35.4% from a total of 110 isolates, with an intermediate resistance of 32.7% and a high resistance of 2.7%. The penicillin resistance of S. pneumoniae carried in the nasopharynx was determined to be 41.5% in the group of sick children and 26.6% in the control group (P > 0.05). Resistance rates of other antibiotics were determined as follows: cefotaxime 2.7%, erythromycin 19%, clarithromycin 5.4%, tetracycline 21.8%, trimethoprim-sulfamethoxazole 4.5% and rifampin 0%. CONCLUSIONS: Penicillin resistance of S. pneumoniae has recently become a problem in Turkey. Because of this, we require new strategies to limit the spread of drug-resistant S. pneumoniae.

Pulmonary involvement in childhood-onset systemic lupus erythematosus: a report of five cases.

OBJECTIVE: Systemic lupus erythematosus (SLE) is a chronic systemic disease, which can involve multiple organs such as kidney, skin and brain. Lung is another organ that can be affected. A number of pulmonary complications including pleuritis, pneumonitis, infectious pneumonia, pulmonary haemorrhage, pulmonary hypertension and pneumothorax have been reported in patients with SLE. Pulmonary involvement is relatively frequent in adult patients; it has infrequently been reported in children with SLE. However, pulmonary manifestations may be an initial and/or life-threatening complication of SLE in children. In this paper we aim to emphasize the pulmonary involvement in childhood-onset SLE via description of our patients. METHODS: The patients, who were diagnosed with SLE at the Children's Hospital of Ankara University Medical School between 1993 and 2002, were retrospectively evaluated for evidence of pulmonary involvement. All patients fulfilled at least four of the classification criteria of the American Rheumatism Association. Using a standardized form, we obtained data regarding the age, sex and presenting complaints of the patients, previous therapies given, clinical and laboratory features, treatment and outcome. Informed consent was obtained from all patients. RESULTS: During the 10-yr study period, 16 patients were diagnosed with childhood-onset SLE. Five of them (31%) had pulmonary involvement including acute lupus pneumonitis, invasive pulmonary aspergillosis, cytomegalovirus pneumonia and pulmonary haemorrhage (in two patients). These 5 patients with lupus lung disease are presented in more detail.
