Streptolysins
Rheumatic Fever
A febrile disease occurring as a delayed sequela of infections with STREPTOCOCCUS PYOGENES. It is characterized by multiple focal inflammatory lesions of the connective tissue structures, such as the heart, blood vessels, and joints (POLYARTHRITIS) and brain, and by the presence of ASCHOFF BODIES in the myocardium and skin.
Amoxicillin for fever and sore throat due to non-exudative pharyngotonsillitis: beneficial or harmful? (1/59)
OBJECTIVES: To determine duration of signs and symptoms and adverse reactions after treatment with amoxicillin of patients with fever and sore throat due to non-exudative pharyngotonsillitis. DESIGN: This was a randomized, double-blinded, placebo-controlled trial. Outpatients at four medical centers were enrolled. Patients over 5 years of age presented with fever and sore throat for less than 10 days due to non-exudative pharyngotonsillitis. Cases with any of the following symptoms or illness were excluded: earache, nasal discharge with foul smell, rheumatic fever, valvular heart disease, renal disease, and penicillin hypersensitivity. Amoxicillin or identical placebo at the dosage of 50 mg/ kg per day was given three or four times daily for 7 days. RESULTS: There were 1217 patients enrolled in this study. Some were lost to follow-up, which is the reason for the variability in number of cases in these analyses. After therapy, duration of fever was 2.46 and 2.48 days (P = 0.78) and of sore throat 3.01 and 3.04 days (P = 0.80) in amoxicillin (n = 431) and placebo (n = 436) groups, respectively. Complications were clinically documented in 13 (2.5%) and 16 (3.0%) cases in amoxicillin (n = 527) and placebo (n = 524) groups (P = 0.56). Two cases (0.46% and 0.46%) from each group (n= 433 and 431) were positive by antistreptolysin O antibody determination. The history of carditis and abnormal urinalysis after treatment were not obtained. CONCLUSIONS: Amoxicillin therapy for non-exudative pharyngotonsillitis conferred no beneficial or harmful effect.

A case history is presented of the occurrence of a high binding capacity for native DNA in the serum of a patient on phenylbutazone. This reverted to normal on stopping the drug. The patient also had a reversible neutropenia and leucopenia, and it is suggested that the high anti-DNA binding capacity was a feature of a drug-induced lupus-like phenomenon.

OBJECTIVE: To evaluate the diagnostic value of streptococcal serology in adult early arthritis patients in discriminating between post-streptococcal reactive arthritis (PSRA) and arthritis with other causes. METHODS: The antistreptolysin-O (ASO) and anti-DNase B tests were performed at baseline in 366 consecutive, newly referred early arthritis patients. After 1 yr of follow-up the patients were classified according to international classification criteria and were evaluated for the presence of persistent arthritis. The outcome measures were the predictive value of streptococcal serology for the diagnosis of PSRA and the ability of this serology to discriminate at the first visit between the self-limiting and persistent forms of arthritis. RESULTS: With a positive serological result, the probability of having PSRA increased from 2 to 9%, whereas the probabilities of having rheumatoid arthritis or undifferentiated arthritis continued to be high (23 and 29%). The serological tests did not discriminate between the self-limiting and persistent forms of arthritis. The major Jones criteria apart from arthritis were not observed. CONCLUSION: Streptococcal serology has no diagnostic value in adult early arthritis patients in whom major Jones criteria other than arthritis are not present.

In an outbreak of idiopathic erysipelas ten women patients, aged 42-74, in a long-stay unit of a psychiatric hospital were simultaneously affected. Group A streptococci M-type 1 were isolated from two isolated from two patients with erysipelas and 18 carriers, but subsequent serological tests for type-specific antibody, antistreptolysin O, and anti-deoxyribonuclease B showed that the infection had been widespread in the unit. Treatment with ampicillin proved ineffective and to prevent relapse it was substituted by a standard course of intramuscular penicillin. This seems to be the first epidemic of this type to be reported and certainly the first outbreak of idiopathic erysipelas to be investigated by modern serological techniques. (+info)Rheumatic fever in a high incidence population: the importance of monoarthritis and low grade fever. (5/59)
AIMS: To describe the clinical features of rheumatic fever and to assess the Jones criteria in a population and setting similar to that in many developing countries. METHODS: The charts of 555 cases of confirmed acute rheumatic fever in 367 patients (97% Aboriginal) and more than 200 possible rheumatic fever cases from the tropical "Top End" of Australia's Northern Territory were reviewed retrospectively. RESULTS: Most clinical features were similar to classic descriptions. However, monoarthritis occurred in 17% of confirmed non-chorea cases and 35% of unconfirmed cases, including up to 27 in whom the diagnosis was missed because monoarthritis is not a major manifestation. Only 71% and 25% of confirmed non-chorea cases would have had fever using cut off values of 38 degrees C and 39 degrees C, respectively. In 17% of confirmed non-chorea cases, anti-DNase B titres were raised but antistreptolysin O titres were normal. Although features of recurrences tended to correlate with initial episodes, there were numerous exceptions. CONCLUSIONS: Monoarthritis and low grade fever are important manifestations of rheumatic fever in this population. Streptococcal serology results may support a possible role for pyoderma in rheumatic fever pathogenesis. When recurrences of rheumatic fever are common, the absence of carditis at the first episode does not reliably predict the absence of carditis with recurrences. (+info)Poststreptococcal nephritis--a rare disease?. (6/59)
Forty-three children presenting with acute nephritis were studied for evidence of preceeding steptococcal infection. They were compared with a group of control children of similar age. Two-thirds of those with nephritis gave a history of a preceeding respiratory infection (compared with one-third of the controls). A significant rise of antistreptolysin O tire occurred in only 16 children with nephritis and within this minority several did not show a fall of serum C3 level. It is probable that only one-third of the children with acute nephritis had poststreptoccoccal glomerulonephritis. Poststreptococcal glomerulo-nephritis is no longer the main cause of childhood acute nephritis in the Leeds area. There may be many different aetiological factors and this diversity calls for more rigorous investigations and a more guarded prognosis.

Two hundred and ninety-four New Zealand secondary school students were examined by questionnaire, and physical and biochemical methods. The sample contained almost equal numbers of Maoris and Europeans. The findings related to joint conditions are presented. Past injury and rheumatic disease accounted for some of the reported morbidity, but no important sex or race differences in these factors emerged. There were, however, significant differences in serum uric acid levels with the Maori having higher levels than the Europeans. A significant correlation with body mass was present in both race and sex groups but a correlation with haemoglobin was present only in the European females. While hyperuricaemia was not associated with morbidity in this young sample, ethnic differences anticipated the higher prevalence of gout already observed in Maori men.

In a survey of the general population the presence or absence of osteoarthrosis of the hand was determined radiologically in 685 adults (300 males and 385 females). Of these, 261 (124 males and 137 females), chosen randomly, were given a complete clinical examination of the musculoskeletal system which included x-ray of joints elsewhere in the body. Osteoarthrosis (OA) scores for the hand and for all body sites were computed for each subject by summing the number of affected joints. For all subjects soical class, height, weight, total serum protein, serum uric acid, haemoglobin, antistreptolysin O, (ASO), C-reactive protein (CRP), and rheumatoid factor were also measured. Analyses were carried out by simple comparison of means and by calculating multiple regressions and correlations. (+info)

- Antistreptolysin-O titer was negative. (cdc.gov)
- A high titer of antistreptolysin O (ASO) shows recent streptococcal infection, indicating the possibility of poststreptococcal glomerulonephritis. (medscape.com)
- Because 20% of patients with documented infection do not show a rise in the antistreptolysin titer, other antistreptococcal antibodies such as anti-deoxyribonuclease (DNAse) B, anti-DNAse, and antihyaluronidase should be tested if ASO findings are negative. (medscape.com)
- however, other signs and symptoms differ, and unlike patients with RA, laboratory studies in patients with rheumatic fever reveal an elevated antistreptolysin O titer. (medscape.com)
