Tonsillitis and sexually transmitted infections like gonorrhea and chlamydia can also cause a sore throat. Strep throat causes nearly 20-30% of sore throat cases in children. The most common one is strep throat, an infection of the throat and tonsils caused by group A Streptococcus bacteria. Strep throat and other bacterial infectionsīacterial infections can also cause sore throats. mumps, an infection that causes swelling of the salivary glands in the neckĢ.chickenpox, an infection that causes a fever and an itchy, bumpy rash.measles, an illness that causes a rash and fever.mononucleosis, an infectious disease that’s transmitted through saliva.Among the viruses that cause sore throats are: Sore throat is usually caused by a viral infection. Colds, the flu, and other viral infections Here are eight of the most common sore throat causes. If you experience severe symptoms or if your sore throat lasts longer than one week, talk to a doctor to determine the cause and best course of treatment for you.Ĭauses of sore throats range from infections to injuries. On the other hand, a sore throat caused by a bacterial infection may require treatment with antibiotics to prevent complications. In most cases, a sore throat caused by a viral infection will improve on its own over time without any treatment. bacterial sore throatĪ sore throat is usually caused by viral infections, including the common cold, flu, measles, and chickenpox. If you experience any of these symptoms in addition to a sore throat or have recently been exposed to COVID-19, you may want to consider getting tested. Other possible symptoms of COVID-19 include: COVID-19ĬOVID-19 is a viral infection that can cause a range of symptoms, including a sore throat. Unlike other conditions that can cause a sore throat, strep throat is not associated with coughing, runny nose, pink eye, or hoarseness.Īdditionally, while a sore throat usually improves on its own over time, strep throat requires treatment with an antibiotic. small red spots on the roof of the mouth. red or swollen tonsils, which sometimes have white patches.In addition to a sore throat, strep throat can also cause other symptoms, including: Sore throat may be a symptom of strep throat, which is an infection caused by Streptococcus pyogenes, a type of bacteria. These white patches are more common in strep throat than in a sore throat caused by a virus.Īlong with the sore throat, you may also have symptoms like: Sometimes, white patches or areas of pus will form on the tonsils. Your throat or tonsils might also look red. It may hurt more when you swallow or talk. Liver uptake of N-acetyl-D-cysteine was reflected in organ concentrations 7-fold higher than noted for the L-isomer.The symptoms of a sore throat can vary depending on what caused it. The L-isomer also increased urinary excretion of glutathione-derived acetaminophen metabolites whereas the D-isomer increased only acetaminophen sulfate excretion and reversed the customary predominance of acetaminophen cysteine over the mercapturic acid conjugate. N-acetyl-L-cysteine succeeded in decreasing these measures of acetaminophen hepatotoxicity while driving liver glutathione concentrations 2-3 fold above control values. Oral coadministration of N-acetyl-D-cysteine (1200 mg/kg), however, failed in preventing the elevation of serum alanine aminotransferase activity, in decreasing hepatocellular necrosis, in interdicting covalent binding of the toxic metabolite to hepatocellular proteins and in preventing the depletion of liver glutathione caused by 500 mg/kg of acetaminophen. This led us to compare the conventional L-isomer of the antidote to its nonphysiologic stereoisomer, N-acetyl-D-cysteine, because the latter should be capable of reducing the toxic metabolite but not of stimulating glutathione biosynthesis. Elevated glutathione may be responsible for inhibiting covalent binding but above-normal concentrations have never been demonstrated in vivo after N-acetyl-L-cysteine treatment or separated adequately from other possible hepatoprotective actions including direct reduction of the toxic acetaminophen metabolite by the antidote. The revelation that many covalent binding estimates are falsely low due to flawed normalization discloses that protection by N-acetyl-L-cysteine against acetaminophen hepatotoxicity is accompanied routinely by a 50 to 80% decline in arylation.
