Glomerulonephritis Streptococcal

The goals of therapy for streptococcal pharyngitis are to eradicate infection in order to prevent complications, shorten the disease course, and reduce infectivity and spread to close contacts. Sequelae that can be prevented by antibiotic use are peritonsillar or retropharyngeal abscess, cervical lymphadenitis, and rheumatic fever. There is no evidence that antibiotic use has an impact on the incidence of poststreptococcal glomerulonephritis. 

Post-streptococcal glomerulonephritis is the result of infection with the nephritogenic strain of group A hemolytic streptococci. The streptococci are usually isolated from patients with a sore throat and, in developing countries, skin infection like impetigo or infected scabies is an important cause. There is no specific treatment except for antihypertensives, salt restriction and diuretics. Corticosteroids are of no value. The disease is self-limiting but, in some adults, it may progress to chronic renal failure.

Pharyngitis is the most common disease produced by S. pyogenes. Penicillin-resistant isolates of this organism have yet to be observed. The preferred oral therapy is with penicillin V, 500 mg every 6 hours for 10 days. Equal results are produced by the administration of 600,000 units of penicillin G procaine intramuscularly once daily for 10 days or by a single injection of 1.2 million units of penicillin G benzathine. Parenteral therapy is preferred if there are questions of patient compliance. Penicillin therapy of streptococcal pharyngitis reduces the risk of subsequent acute rheumatic fever but not of poststreptococcal glomerulonephritis. 

The interaction that results in neutralisation of the thrombolytics is established and clinically important. One author says that clinically, therapy is not repeated within a year as it would not work. Given that it has been suggested that the effects may be very persistent, it would seem prudent, if a second use is needed, to use a thrombolytic with less antigenic effects such as alteplase. The British National Formulary says that streptokinase should not be used again beyond 4 days of the first use of either streptokinase or anistreplase. In addition, the manufacturer recommends avoidance of streptokinase in patients who have had recent streptococcal infections that have produced high anti-streptokinase titres, such as acute rheumatic fever or acute glomerulonephritis. ... 

Biliary tract Biliary pseudolithiasis has been reported in three Chinese children with renal diseases, two with nephrotic syndrome and one with post-streptococcal glomerulonephritis with acute renal failure, who were given ceftriaxone [17 ]. 

Streptococcus pyogenes may get into foods from infected handlers since they are carried on airb)orne droplets from the respiratory tract of infected people who may sneeze or cough on food. The disease caus by this bacteria is commonly called strep throat. Other Streptococcal bacteria can get into the food and cause scarlet fever. However, this is uncommon in the United States today. These diseases are characterized by fever, vomiting, and sore throat. To prevent their spread, food should E)e protected from contamination by infected handlers. Once contracted, the disease responds to penicillin and other antibiotics. Occasionally streptococcal infections produ(3e cxjmplications such as rheumatic fever and glomerulonephritis.
