Best Antibiotic For Group B Strep Uti

Symptoms Of Group B Streptococcal Infection

How much dose of an antibiotic is sufficient for Strep Throat? – Dr. Sriram Nathan

The signs and symptoms of GBS vary according to age, but can include:

  • in non-pregnant adults fever, headache, confusion, shortness of breath or cough , a burning sensation when passing urine or frequent visits to the toilet to pass urine , or red, swollen and painful skin
  • in pregnant women fever, abdominal swelling, uterine tenderness
  • in newborns shortness of breath or difficulty breathing, lethargy, low blood pressure
  • in babies aged between one week and a few months fever, lethargy, irritability, poor feeding, seizures.

What Is The Risk Of Death If The Baby Has An Early Gbs Infection

Researchers have estimated that the death rate from early GBS infection is 2 to 3% for full-term infants. This means of 100 babies who have an actual early GBS infection, 2-3 will die. Death rates from GBS are much higher in infants who are born at less than 33 weeks gestation .

Although the death rate of GBS is relatively low, infants with early GBS infections can have long, expensive stays in the intensive care unit. Researchers have also found that up to 44% of infants who survive GBS with meningitis end up with long-term health problems, including developmental disabilities, paralysis, seizure disorder, hearing loss, vision loss, and small brains. Very little is known about the long-term health risks of infants who have GBS without meningitis, but some may have long-term developmental problems .

How Is Group B Strep Diagnosed

Pregnant women are routinely tested for GBS late in the pregnancy, usually between weeks 35 and 37. The test is simple, inexpensive, and painless. Called a culture, it involves using a large cotton swab to collect samples from the vagina and rectum. These samples are tested in a lab to check for GBS. The results are usually available in 1 to 3 days.

If a test finds GBS, the woman is said to be “GBS positive.” This means only that she has the bacteria in her body not that she or her baby will become sick from it.

GBS infection in babies is diagnosed by testing a sample of blood or spinal fluid. But not all babies born to GBS-positive mothers need testing. Most healthy babies are simply watched to see if they have signs of infection.

What Happens If You Test Positive For Group B Strep During Pregnancy

The Faith Cause: Increasing Group B Strep Awareness

Healthcare providers prevent GBS infection in your baby by treating you with intravenous antibiotics during labor and delivery. The most common antibiotic to treat group B strep is penicillin or ampicillin. Giving you an antibiotic at this time helps prevent the spread of GBS from you to your newborn. It’s not effective to treat GBS earlier than at delivery. The antibiotics work best when given at least four hours before delivery. About 90% of infections are prevented with this type of treatment.

One exception to the timing of treatment is when GBS is detected in urine. When this is the case, oral antibiotic treatment begins when GBS is identified . Antibiotics should still be given through an IV during labor.

Any pregnant person who has previously given birth to a baby who developed a GBS infection or who has had a urinary tract infection in this pregnancy caused by GBS will also be treated during labor.

Indications For Intrapartum Antibiotic Prophylaxis

Indications for intrapartum antibiotic prophylaxis are listed inTable 1 .

Exceptions to universal prenatal GBS vaginalrectal culture are women who have GBS bacteriuria identified at any time during the current pregnancy and those who have previously given birth to a neonate with GBS EOD because these risk factors are overriding indications for intrapartum antibiotic prophylaxis. All women whose vaginalrectal culture at 36 0/737 6/7 weeks of gestation are positive for GBS should receive appropriate intrapartum antibiotic prophylaxis, unless a prelabor cesarean birth is performed in the setting of intact membranes. Women with a positive prenatal GBS culture result who undergo a cesarean birth before the onset of labor and with intact membranes do not require GBS antibiotic prophylaxis 62.

Women with reported or known GBS colonization status in a previous pregnancy and who present in labor at 37 0/7 weeks of gestation or more with unknown culture status in the current pregnancy also should be considered candidates to receive antibiotic prophylaxis intrapartum.

Can Uti Symptoms Linger After I Take Antibiotics

Since UTI symptoms usually improve just a few days after starting antibiotics, youll want to talk to your healthcare provider if you notice that UTI symptoms are still hanging around after finishing your antibiotics.

Theres no need to panic, but you and your healthcare provider will want to make sure the antibiotics actually worked against your UTI. To do this, they may take another sample of your urine to see if the bacteria are still there or not. If the infection is cured, youll want to be sure there isnt a different issue thats causing similar symptoms.

Causative Factors And Pathogenesis

Escherichia coli is the predominant uropathogen isolated in acute community-acquired uncomplicated UTIs, followed by Staphylococcus saprophyticus . Enterococcus, Klebsiella, Enterobacter, and Proteus species are less common causes.7

In recurrent uncomplicated UTIs, reinfection occurs when the initially infecting bacteria persist in the fecal flora after elimination from the urinary tract, subsequently recolonizing the introitus and bladder.1 A number of host factors appear to predispose otherwise healthy young women to recurrent UTIs. These include local pH and cervicovaginal antibody changes in the vagina greater adherence of uropathogenic bacteria to the uroepithelium and possibly pelvic anatomic differences, such as shorter urethra-to-anus distance.

Diabetes mellitus, neurologic conditions, chronic institutional residence, and chronic indwelling urinary catheterization are important predisposing factors for complicated UTIs. In affected patients, organisms that are typically less virulent may cause marked illness, although E. coli infection remains the most common organism in nearly all patient groups. Klebsiella and group B streptococcus infections are relatively more common in patients with diabetes, and Pseudomonas infections are relatively more common in patients with chronic catheterization. Proteus mirabilis i s a c ommon u ropathogen i n p atients with indwelling catheters, spinal cord injuries, or structural abnormalities of the urinary tract.7

If Your Baby Gets Gbs Do Signs Of Infection Or Other Problems Show Up Right After Birth

What is a Group B Strep Test?

Not always. It depends on the kind of GBS infection your baby has. There are two kinds of GBS infections:

  • Early-onset GBS: Signs like fever, trouble breathing and drowsiness start during the first 7 days of life, usually on the first day. Early-onset GBS can cause pneumonia, sepsis or meningitis. If you have GBS, you can pass this kind of infection to your baby. But treatment with antibiotics during labor and birth can help prevent your baby from getting it. About half of all GBS infections in newborns are early-onset.
  • Late-onset GBS: Signs like coughing or congestion, trouble eating, fever, drowsiness or seizures usually start when your baby is between 7 days and 3 months old. Late-onset GBS can cause sepsis or meningitis. If you have GBS, you can pass this kind of infection to your baby during or after birth. Treatment with antibiotics during labor and birth does not prevent late-onset GBS. After birth, your baby also can get GBS from other people who have the infection.

    When Gbs Status Is Unknown

    Your doctor screens for GBS between 35 and 37 weeks. So, if you go into labor early, you may not have had your screening yet. Additionally, if you missed this prenatal appointment or do not have prenatal care, may not know your group B strep status. If your GBS status is unknown, you will receive antibiotics when you get to the hospital in labor.

    What Are Potential Side Effects Of Antibiotics For Uti

    In addition to the notable side effects weve already covered, there are a few more potential antibiotic side effects youll want to know about.

    Most antibiotics can cause some degree of stomach upset like nausea, vomiting, and/or diarrhea. If you have severe diarrhea or diarrhea that lasts for 2 or more days, let your healthcare provider know. Diarrhea is a common side effect while taking antibiotics and just after finishing them. But in some cases, diarrhea from antibiotics can be a sign of a more serious infection caused by Clostridium difficile bacteria.

    Some people are also sensitive to antibiotics, which could result in a minor reaction like a rash or a more serious reaction like anaphylaxis. If you notice difficulty breathing or major skin changes after taking an antibiotic, get medical help right away.

    Can Gbs Cause Problems For Mom During And After Pregnancy

    Gbs Test Pregnancy

    GBS can cause a uterine infection during and after pregnancy. Symptoms of a uterine infection include:

    • Fever
    • Pain in your belly
    • Increased heart rate

    If you have a uterine infection, your provider can give you antibiotics, and the infection usually goes away in a few days. Some women have no symptoms, so they dont get treatment. Without treatment, infection during pregnancy may increase your chances of:

    • Premature rupture of the members When the amniotic sac breaks after 37 weeks of pregnancy but before labor starts
    • Preterm labor Labor that happens too early, before 37 weeks of pregnancy
    • Stillbirth When a baby dies in the womb after 20 weeks of pregnancy

    If youre treated for GBS during labor and birth, you probably wont get a uterine infection after your baby is born.GBS also can cause a UTI during pregnancy. A UTI can cause fever or pain and burning when you urinate. Sometimes a UTI doesnt have any symptoms. If you have a UTI, you may find out about it from a urine test during one of your prenatal visits.If you have a UTI caused by GBS, your provider gives you antibiotics to take by mouth during pregnancy. You also get antibiotics through an IV during labor and birth, because you may have high levels of GBS in your body.

    What Types Of Health Care Professionals Treat Group B Strep Infections

    Group B strep infections may be diagnosed and treated by different specialists, depending on the patient’s age and the potential complications encountered by the patient. In pregnant women, a GBS infection may be diagnosed and treated during labor by the patient’s obstetrician/gynecologist or by a family practitioner if they are delivering the baby. Babies who develop a GBS infection will be treated by a pediatrician or a neonatologist, and sometimes an infectious disease specialist may be involved. Nonpregnant adults who develop GBS infection will frequently be treated by their family physician, an internist, or an infectious disease specialist, and rarely by a general or orthopedic surgeon if a skin or bone infection requiring surgery is present.

    When Should I See My Healthcare Provider If Im Positive For Group B Strep

    In some cases, GBS causes infections during pregnancy. Symptoms of infection include fever, pain and increased heart rate. Let your provider know if you have any of those symptoms as it could lead to preterm labor.

    GBS can also cause urinary tract infection , which requires oral antibiotics.

    Talk to your provider about what you can expect during labor and delivery if you have group B strep.

    A note from Cleveland Clinic

    Try not to panic if your healthcare provider tells you you’re positive for group B strep during pregnancy. It’s caused by bacteria that occur naturally in your body, not by anything you did wrong. The chances of you passing group B strep to your baby are quite low, especially if you take antibiotics during labor. Talk to your provider about group B strep and share any concerns you have. In most cases, testing positive for GBS causes no problems, and your baby is healthy.

    What Is The Evidence For Antibiotics During Labor To Prevent Early Gbs Infection

    To answer this question, I will walk you through the most important studies that led to how we most commonly try to prevent early GBS infections in the U.S. today.

    GBS emerged as a widespread threat to newborns in the early 1970s. At that time, 1.7 of every 1,000 infants had early GBS infection . In 1973, a researcher proposed giving pregnant women penicillin to stop early GBS infections in infants .

    First, researchers tried giving penicillin to women before labor, but this didnt work. Although penicillin temporarily lowered GBS levels, by the time women went into labor the GBS levels were back up again .

    Next, researchers tried giving antibiotics to those with GBS during labor. In the late 1980s, three groups of researchers in the U.S., Spain, and Finland randomly assigned women with GBS to either receive IV antibiotics during labor or no antibiotics .

    In a recent Cochrane review, researchers combined the results of these 3 studies, with a total of 500 pregnant women. They found that when women with GBS had antibiotics during labor, their infants risk of catching early GBS infection dropped by 83% .

    Amoxicillin/potassium Clavulanate Cefdinir Or Cephalexin

    Group B StrepâTesting and Treatment Explained

    How it Works: is another combination drug that belongs to the penicillin class of antibiotics. and belong to a different class of antibiotics thats closely related to penicillins.

    All three antibiotics kill bacteria by destroying one of its most important components: the cell wall, which normally keeps bacteria structurally intact.

    Common doses:

    • Amoxicillin/clavulanate: 500 twice a day for 5 to 7 days

    • Cefdinir: 300 mg twice a day for 5 to 7 days

    • Cephalexin: 250 mg to 500 mg every 6 hours for 7 days

    Notable side effects: Diarrhea, nausea, vomiting, and rash are common side effects of these antibiotics. In rare cases, all three have the potential to cause the dangerous skin reactions, SJS and TEN.

    If you have a penicillin allergy, your healthcare provider wont prescribe amoxicillin/clavulanate. They may or may not prescribe cefdinir or cephalexin since there is a small chance that a person with a penicillin allergy may also be allergic to these two.

    Detection And Identification Of Gbs

    The majority of GBS infections can be diagnosed through routine laboratory testing of clinical samples such as blood, cerebrospinal fluid, or aspirates from sites of local suppuration. In the majority of cases isolates are rapidly identified by typical colony morphology on agar medium such as tryptic soy agar-5% sheep blood, and are tested for catalase, which streptococci do not express. Isolates are grouped into the Lancefield B group using commercial typing antisera for latex agglutination assays. GBS antigens can occasionally be detected in blood, cerebrospinal fluid, and urine but are not routinely tested for in any diagnostic assays. A Gram stain of a clinical specimen can be useful in the detection of infection but is not specific and therefore not definitive for identification. Polymerase chain reaction and optical immunoassay may, on the other hand, provide rapid and specific results for the detection of GBS infection however, optimization and validation of these assays to ensure sensitivity and specificity has limited their widespread application in the clinical laboratory .

    How Can You Protect Your Baby From Gbs

    If your GBS test at 35 to 37 weeks shows you have the infection, your provider gives you medicine called an antibiotic during labor and birth through an IV . You also may be treated if you have any risk factors for GBS and you dont know your GBS test results or you havent been tested yet. Treatment with antibiotics helps prevent your baby from getting the infection.Penicillin is the best antibiotic for most women. Another antibiotic called ampicillin also can be used. These medicines usually are safe for you and your baby. But some women treated with penicillin have a mild allergic reaction, like a rash. About 1 in 10,000 women have a serious allergic reaction that needs to be treated right away. If youre allergic to penicillin, your provider can treat you with a different medicine.If your test shows you have GBS, remind your health care providers at the hospital when you go to have your baby. This way, you can be treated quickly. Treatment works best when it begins at least 4 hours before childbirth.If you have GBS and youre having a scheduled cesarean birth before labor starts and before your water breaks, you probably dont need antibiotics.Its not helpful to take oral antibiotics before labor to treat GBS. The bacteria can return quickly, so you could have it again by the time you have your baby.
