Impact Of The Rectal Microbiome On Chlamydia
The unique microbiome of the rectum is another factor that may make rectal chlamydia more difficult to clear. In vivo, IFN- up-regulates the enzyme indoleamine 2,3-dioxygenase, which depletes tryptophan. The genital strains of chlamydia are tryptophan auxotrophs, but have retained the trpBA genes in the tryptophan biosynthesis pathway. This enables them to back-synthesize tryptophan from indole, a compound that is present in the rectum as a product of some bacteria . The availability of indole in the rectum could aid the recovery of chlamydia at this site from attack by the host and could therefore influence how well chlamydia responds to treatment and is cleared. While there is ongoing research investigating the role of the microbiome in cervical chlamydia infection, it should also be investigated for its role in sustaining rectal infection.
When Was Azithromycin First Approved As An Antibiotic
Azithromycin is an antibiotic in the macrolides class. The Food and Drug Administration first approved azithromycin in 1991. Like all antibiotics, azithromycin can only fight certain bacteria. For this reason, it is important to talk to a doctor before taking the drug. It is not effective against viral infections or as a pain reliever.
How Is It Contracted
Chlamydia is transmitted primarily through sexual activity. The following are the most common ways:
- unprotected intercourse with an infected partner
- oral sex, although a less common cause of infection as bacteria Chlamydia trachomatis targets the genital area rather than the throat. Although it is possible theoretically, the cases of infestation from mouth-to-penis and penis-to-mouth contact are rare
- vagina, cervix, anus, penis or mouth contacting infected secretions or fluids which means that contraction can occur even if the penis or tongue does not enter the vagina or anus
- bacteria can travel from the vaginal area to the anus or rectum of women while wiping with toilet paper
- sharing sex toys
- from mother to the newborn during vaginal childbirth through the infected birth channel
- infection can be transferred on fingers from the genitals to other parts of the body
Chlamydia is not contracted through simple kissing, handshaking, any casual contacts, sharing baths, towels and cups as well as from toilet seats.

Long Term Complications Of Chlamydia In Males
In men, chlamydia can be diagnosed from a urine test / swab, even if you have no symptoms. In 50% of men who test positive, chlamydia symptoms are absent. However if untreated, because chlamydia also causes inflammation in the male genital tract, this may result in the following.
- Urethritis pain within the penis and on passing urine, often with discharge
- Epididymo-orchitis painful, swollen testicles
- Prostatitis a painful, swollen, prostate gland
- Chlamydial infection also affects male fertility. Semen is poorer quality, and as it is packed full of inflammatory cells, sperm are less ability to swim freely.
How Accurate Are The Tests
The accuracy of a chlamydia test depends on the kind of test used and the type of sample thats collected. The recommended tests are over 95% accurate in picking up chlamydia. As no test is 100% accurate theres a small chance that the test will give a negative result when you do have chlamydia. This is known as a false negative result. This can sometimes explain why you might get a different result from another test or why you and a partner might get a different test result.
Its possible for the test to be positive if you havent got chlamydia, but this is rare.

What Antibiotics Are Used To Treat Chlamydia
Currently, NICE recommends Azithromycin or Doxycycline as the first-line drugs for uncomplicated genital chlamydia infections. According to their guidelines, Doxycycline is preferred in instances where the patient shows signs of a rectal infection. Azithromycin is used in other cases.
- Doxycycline is given as a 100mg tablet, taken twice daily for one week.
- Azithromycin is issued for use over three days. A 1g dose on the first day, followed by two 500mg doses.
When Can I Have Sex Again
If you had doxycycline, you shouldn’t have sex including vaginal, oral or anal sex, even with a condom until both you and your partner have completed treatment.
If you had azithromycin, you should wait 7 days after treatment before having sex .
This will help ensure you don’t pass on the infection or catch it again straight away.

How Will I Know If I Have Chlamydia
You can only be certain you have chlamydia if you have a test.
Anyone can get chlamydia. Youre more likely to have it if youre under 25, have a new sexual partner, or more than one sexual partner in the last year, and if you havent used condoms.
You should have a test if:
- you, or a partner, have or think you might have symptoms
- youve recently had sex without a condom with a new partner
- you, or a partner, have had sex without a condom with other partners
- during a vaginal examination, your doctor or nurse says that the cervix is inflamed and/or theres an unusual discharge
- a sexual partner tells you they have a sexually transmitted infection
- you have another STI.
If you live in England, and youre a woman who is under 25 and sexually active, its recommended that you have a chlamydia test when you change sexual partner and once a year.
If youre a man who is under 25 and sexually active, its recommended that you have a chlamydia test once a year if you are not using condoms with new or casual partners.
You could still have chlamydia even if a partner has tested negative. The only way to make sure you dont have chlamydia is to get tested yourself.
If you have chlamydia, youll be encouraged to be tested for other STIs as you can have more than one STI at the same time.

What Is The Treatment For Chlamydia
Chlamydia can be easily cured with antibiotics. HIV-positive persons with chlamydia should receive the same treatment as those who are HIV-negative.
Persons with chlamydia should abstain from sexual activity for 7 days after single dose antibiotics or until completion of a 7-day course of antibiotics, to prevent spreading the infection to partners. It is important to take all of the medication prescribed to cure chlamydia. Medication for chlamydia should not be shared with anyone. Although medication will stop the infection, it will not repair any permanent damage done by the disease. If a persons symptoms continue for more than a few days after receiving treatment, he or she should return to a health care provider to be reevaluated.
Repeat infection with chlamydia is common. Women whose sex partners have not been appropriately treated are at high risk for re-infection. Having multiple chlamydial infections increases a womans risk of serious reproductive health complications, including pelvic inflammatory disease and ectopic pregnancy. Women and men with chlamydia should be retested about three months after treatment of an initial infection, regardless of whether they believe that their sex partners were successfully treated.
Infants infected with chlamydia may develop ophthalmia neonatorum and/or pneumonia. Chlamydial infection in infants can be treated with antibiotics.
Does The Treatment Work
Usually, yes. You can infect another sex partner as soon as you get chlamydia. Most women and some men do not have early signs of the disease.
A pregnant women can also pass on the infection to her baby as it is being born. This can lead to infection of the eyes and lungs in the infant. It is important to inform people you have had sex with during the past 3 months because they may have the disease and not know they need treatment. Your public health nurse will contact your partner if you prefer. Your name will be kept confidential.

Does Chlamydia Cause Cervical Cancer
No, chlamydia doesn’t cause cervical cancer.
It’s possible to get a sexually transmitted infection by having sex with someone who has an STI, even if they have no symptoms.
The following measures will help protect you from most STIs including chlamydia, gonorrhoea and HIV.
If you have an STI, they’ll also help prevent you from passing it on to someone:
- Use condoms every time you have vaginal or anal sex.
- If you have oral sex , use a condom to cover the penis, or a dam to cover the vulva or anus.
- Avoid sharing sex toys. If you do share them, wash them or cover them with a new condom before anyone else uses them.
What Happens If You Dont Get Treated For Chlamydia
Even though chlamydia is common and doesnt usually cause any symptoms, it can become a big deal if its not caught and treated early.
Chlamydia can spread to your uterus and fallopian tubes if it goes untreated for a long time. This can cause you to have pelvic inflammatory disease . PID can cause permanent damage that leads to pain, infertility, or ectopic pregnancy. So getting tested regularly for chlamydia really lowers your chances of getting PID.
If you have a penis, a chlamydia infection can spread to your epididymis if its left untreated, and can cause chronic joint pain. Rarely, it can make you infertile.
Having chlamydia may increase your chances of getting or spreading HIV.
If you have chlamydia during your pregnancy and dont treat it, you can pass it to your baby when youre giving birth. Chlamydia can also cause eye infections and pneumonia in newborns, and it also increases the risk of delivering your baby too early.
Testing and treatment for chlamydia is quick, easy, and the best way to avoid all of these problems.

Taking Doxycycline To Treat Chlamydia
Dose: Doxycycline, one 100mg capsule twice a day for 7 days.
Your doctor or other health professional will assess your suitability for doxycycline or an alternative.
Taking doxycycline
- Swallow the capsules whole do not break, chew, or crush the capsules.
- If you take it with food you are less likely to feel sick.
- Stay upright while swallowing it ie standing, or sitting not lying down.
- The most common side effects are headaches, and nausea.
Special precautions

Do not take doxycycline if:
- You are under 12 years old as it can stain your teeth.
- You are pregnant.
- You are allergic to it.
- You have kidney or liver disease.
- Or if you have
It is now possible to purchase a 7-day course of doxycycline from Dr Fox online. This is safe, quick and convenient. In the light of this new advice, Dr Fox has now discontinued selling azithromycin for chlamydia infection.
Ophthalmia Neonatorum Caused By C Trachomatis
A chlamydial etiology should be considered for all infants aged 30 days who experience conjunctivitis, especially if the mother has a history of chlamydial infection. These infants should receive evaluation and age-appropriate care and treatment.
Preventing Ophthalmia Neonatorum Caused by C. trachomatis
Neonatal ocular prophylaxis with erythromycin, the only agent available in the United States for this purpose, is ineffective against chlamydial ophthalmia neonatorum . As an alternative, prevention efforts should focus on prenatal screening for C. trachomatis, including
Neonates born to mothers for whom prenatal chlamydia screening has been confirmed and the results are negative are not at high risk for infection.
Diagnostic Considerations
Treatment
Erythromycin base or ethylsuccinate 50 mg/kg body weight/day orally, divided into 4 doses daily for 14 days*
* An association between oral erythromycin and azithromycin and infantile hypertrophic pyloric stenosis has been reported among infants aged < 6 weeks. Infants treated with either of these antimicrobials should be followed for IHPS signs and symptoms.
Although data regarding use of azithromycin for treating neonatal chlamydial infection are limited, available data demonstrate that a short therapy course might be effective . Topical antibiotic therapy alone is inadequate for treating ophthalmia neonatorum caused by chlamydia and is unnecessary when systemic treatment is administered.
Follow-Up

Summary Of The Evidence
There is no evidence relating to patient values and preferences but the Guideline Development Group agreed that there is probably no variability in the values people place on the outcomes. Research related to other conditions indicates that adherence may be improved with simpler medication regimens. The GDG therefore agreed that azithromycin may be more acceptable to patients since it is a single dose regimen . There is little to no evidence for equity issues and feasibility. Resistance in other infections that often co-occur with chlamydia may restrict the use of some medicines, such as ofloxacin. For many of these medicines, costs may differ between countries in places with high incidence of chlamydia, the cost differences between azithromycin and doxycycline may be large due to greater numbers of people requiring treatment.
In summary, there was moderate quality evidence for trivial differences in benefits and harms between azithromycin and doxycycline, and although the cost of azithromycin is higher, the single dose may make it more convenient to use than doxycycline. While the differences are also trivial with the other medicines, the evidence is low quality and these are therefore provided as alternatives, with the exception of delayed-release doxycycline, which is currently expensive.
See for list of references of reviewed evidence, and for details of the evidence reviewed, including evidence profiles and evidence-to-decision frameworks .
How Antibiotics For Chlamydia Are Administered
Antibiotics for uncomplicated genital chlamydia infections are taken orally.
- Where Azithromycin is used, it is given as a three day course. This will usually be two 500mg tablets on the first day, followed by one 500mg tablet on the second and third days.
- If Doxycycline is used, NICE recommends 100mg taken twice a day for one week. So one dose might be one 100mg tablet, or two 50mg tablets.
- Ofloxacin might be given as a once daily 400mg dose for one week, or a 200mg dose twice daily for one week.
- Erythromycin for chlamydia might also be prescribed in one of two ways: as a 500mg dose taken four times daily for one week or as a 500mg dose taken twice a day for up to two weeks.
- Amoxicillin is given as a 500mg dose , taken three times daily for one week.
However, in any case, you should always follow the specific instructions issued to you by your doctor.

Can You Get Chlamydia More Than Once
Yes, you can get the infection even if youve successfully treated it already.
A sexual partner who has chlamydia can transmit it to you again, even if youve already had it and treated it.
You can also get chlamydia again if it wasnt fully treated the first time. This can happen if you stop taking the necessary treatment. Its important to complete the antibiotics youve been given, even if your symptoms get better.
The CDC recommends getting tested 3 months after treatment of your initial infection to ensure the infection is cleared.
Will I Need To Go Back To The Clinic
If you take your antibiotics correctly, you may not need to return to the clinic.
However, you will be advised to go back for another chlamydia test if:
- you had sex before you and your partner finished treatment
- you forgot to take your medication or didn’t take it properly
- your symptoms don’t go away
- you’re pregnant
If you’re under 25 years of age, you should be offered a repeat test for chlamydia 3 to 6 months after finishing your treatment because you’re at a higher risk of catching it again.

What Other Information Should I Know
Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your body’s response to azithromycin.
Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of infection after you finish the azithromycin, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
