Abstract Background Acute rheumatic fever (ARF) still a very common condition and constitutes a real public health problem in the developing countries including Algeria. The objective is to assess the epidemiological and clinical profile and the disease course of ARF in our region and estimate the incidence of cardiac complications. Method The authors report the results of a retrospective study of 52 cases of ARF in children, hospitalized and treated at the Sainte Therese Clinic of the CHU Annaba for a period of 6 years. The diagnosis was made according to Jones criteria. Information was obtained from hospital records. Results The disease mainly concerned the age group of 4–10 years (52%), the sex ratio was 0.86 (28 girls, and 24 boys). The maximum number of hospitalizations is observed during the rainfall period (October-March). 54% of patients had untreated angina. Clinically, fever was noted in 23 patients, polyarthritis in third of cases and a heart murmur in half of patients. Doppler-coupled echocardiography founded carditis in 73% of patients: Endocarditis was noted in all of these cases and the mitral insufficiency was the dominant anatomo-clinical form. The number of infra-clinical carditis was considerable (10/38 cases of carditis). Biologically, accelerated ESR (> 50 mm/H1) was observed in 65% of cases, high CRP level and hyper leucocytosis were noted in 38 and 31 patients, respectively. ASLOs were high in 85% of cases. The outcomes were favorable in the majority of cases. Nevertheless 5 relapses were recorded, including 3 complicated by severe carditis. Conclusion ARF still frequent in our region. Cardiac complications are always frequent and constitute a major factor of morbidity. Our results illustrate the absolute need for a rigorous application of the national prevention program, the main objective of which is to reduce the prevalence of rheumatic heart disease.

BACKGROUND Pharyngotonsillitis is defined as a spectrum of conditions ranging from inflammation primarily confined to the tonsils to pharyngitis implying generalized inflammation of the whole of pharynx. Children are more prone to get several episodes of pharyngotonsillitis per year during their school years. Pharyngitis caused by Streptococcus pyogenes can cause two non-suppurative complications, acute rheumatic fever and acute glomerulonephritis which is responsible for significant morbidity and mortality. The present study was conducted to identify the prevalence of bacterial pathogens causing pharyngotonsillitis and to study their antibiotic sensitivity pattern that would indicate the optimum line of treatment. METHOD A total of 200 children at the age group of 2 - 12 years who had clinical features of pharyngotonsillitis according to the inclusion criteria were recruited for this study over a period of one year. With the help of a disposable wooden spatula, pus from the pharyngo tonsillar region was collected and processed. Predominant isolates obtained were identified and antibiotic sensitivity was done. RESULTS Bacteria was isolated from 70 samples. Pharyngotonsillitis was found most prevalent at the age group of 8 – 10 years. Intake of cold food stuffs and passive smoking at home was found to have statistically significant association as risk factor for pharyngotonsillitis. Staphylococcus aureus was the most common organism isolated followed by Streptococcus pyogenes. The other organisms isolated were group G and C streptococci, Streptococcus pneumoniae, Pseudomonas aeruginosa and Klebsiella pneumonia sub species (spp) aerogenes. CONCLUSIONS Staphylococcus aureus was the most common organism isolated, followed by Streptococcus pyogenes. All the isolates of beta haemolytic streptococci were found to be sensitive to penicillin. There was increased incidence of resistance to macrolides among the gram-positive isolates except Streptococcus pneumoniae and it may be due to the wide spread use of macrolides injudiciously. All the bacterial pharyngotonsillitis cases were cured with the antibiotic given according to the sensitivity except one case.

AbstractBackgroundCentral to rheumatic fever (RF) diagnosis is evidence of streptococcal exposure, specifically antistreptolysin O (ASO) and antideoxyribonuclease B (ADB) antibodies. It is unknown if these antibody titers should be adjusted to the background exposure rates of GAS or if published standards should be used. Here, we establish the normal values of ASO and ADB in Uganda and examine RF case detection using published vs. population-specific thresholds.MethodsParticipants (age 0-50 years) were recruited. ASO was measured in-country by nephelometric technique. ADB samples were sent to Australia (PathWest) for ADB determination by enzyme inhibition assay, andthe 80% upper limit values by age were established. The published standard values for ASO (200IU/ml) and ADB (375IU/ml) were compared to the Ugandan 80% upper limit of normal values (ULN) for RF case detection in children 5-15 years.FindingsOf the 428 participants, 16 were excluded from analysis (9 sore throat, 1 skin sores, 5 fever, 4 echocardiograms showing occult RHD), and 183 of the remaining were children 5-15 years. The median ASO titer in this age group was 220 IU/ml, with the 80th percentile value of 389 IU/ml. The median ADB titer in this age group was 375 IU/ml, with the 80th percentile value of 568 IU/ml. Application of new Ugandan cutoffs to 528 children enrolled in our prospective RF study, reduced the number of definite RF cases to 120/528 (22·7%), as compared to 173/528 (32·8%) using published normal values.InterpretationThe 80th percentile ULN for ASO and ADB are higher in Uganda than in other countries. Applying these higher values to RF diagnosis in Uganda results in higher diagnostic specificity, but some unknown loss in sensitivity. Implications of over-diagnosis and missed cases will be explored through a longitudinal follow-up study of children in the RF research program.FundingThis work was supported by American Heart Association Grant #17SFRN33670607 / Andrea Beaton / 2017 and DELTAS Africa Initiative.Research in contextEvidence before this studyWe searched PubMed for data on normal values of streptococcal antibody titers within diverse populations between database inception and January 1, 2019, using the search terms (rheumatic fever) OR (streptococcal antibodies). Nine studies were identified, but only one was from sub-Saharan Africa (2018, Ethiopia) and it was limited by vague exclusion criteria and lack of data on anti-DNase B. Given the high burden of rheumatic heart disease in sub-Saharan Africa, further data is needed to determine normal streptococcal antibody titers in this population and to assess the clinical impact of different cutoffs for RF diagnosis.Added value of this studyOur study utilized a rigorous approach to exclude patients with history of recent possible streptococcal exposure including skin and throat infection and employed echocardiography to exclude patients with pre-existing rheumatic heart disease. Additionally, this study was conducted in parallel to a larger epidemiological cohort study of rheumatic fever in Uganda, allowing us, for the first time, to prospectively determine how utilization of different streptococcal antibody titer cutoffs affect diagnosis of rheumatic fever.Implications of all the available evidenceRheumatic fever remains a challenging diagnosis based on a clinical decision rule with imperfect sensitivity and specificity. Improved understanding of streptococcal antibody titers in rheumatic heart disease endemic populations may improve diagnostic performance. Our study also points to the need for development of a rheumatic fever diagnostic test, in order to provide a more definitive assessment of risk.
