Randomized secondary prevention trial of azithromycin in patients with coronary artery disease: primary clinical results of the ACADEMIC study. (1/356)
BACKGROUND: Chlamydia pneumoniae is associated with coronary artery disease (CAD), although its causal role is uncertain. A small preliminary study reported a >50% reduction in ischemic events by azithromycin, an antibiotic effective against C pneumoniae, in seropositive CAD patients. We tested this prospectively in a larger, randomized, double-blind study. METHODS AND RESULTS: CAD patients (n=302) seropositive to C pneumoniae (IgG titers >/=1:16) were randomized to placebo or azithromycin 500 mg/d for 3 days and then 500 mg/wk for 3 months. The primary clinical end point included cardiovascular death, resuscitated cardiac arrest, nonfatal myocardial infarction (MI), stroke, unstable angina, and unplanned coronary revascularization at 2 years. Treatment groups were balanced, and azithromycin was generally well tolerated. During the trial, 47 first primary events occurred (cardiovascular death, 9; resuscitated cardiac arrest, 1; MI, 11; stroke, 3; unstable angina, 4; and unplanned coronary revascularization, 19), with 22 events in the azithromycin group and 25 in the placebo group. There was no significant difference in the 1 primary end point between the 2 groups (hazard ratio for azithromycin, 0.89; 95% CI, 0.51 to 1.61; P:=0.74). Events included 9 versus 7 occurring within 6 months and 13 versus 18 between 6 and 24 months in the azithromycin and placebo groups, respectively. CONCLUSIONS: This study suggests that antibiotic therapy with azithromycin is not associated with marked early reductions (>/=50%) in ischemic events as suggested by an initial published report. However, a clinically worthwhile benefit (ie, 20% to 30%) is still possible, although it may be delayed. Larger (several thousand patient), longer-term (>/=3 to 5 years) antibiotic studies are therefore indicated. (+info)Cytomegalovirus seropositivity and C-reactive protein have independent and combined predictive value for mortality in patients with angiographically demonstrated coronary artery disease. (2/356)
BACKGROUND: The role of inflammation in coronary artery disease (CAD) is being increasingly recognized. Markers of inflammation (eg, C-reactive protein [CRP]) and infection (eg, seropositivity to Chlamydia pneumoniae, cytomegalovirus [CMV], and Helicobacter pylori) have been proposed as risk factors for CAD, but these associations require further evaluation. METHODS AND RESULTS: We prospectively tested whether CRP levels and IgG seropositivity to C pneumoniae, CMV, and H pylori are predictors of subsequent mortality in 985 consecutive patients with angiographically demonstrated CAD (stenosis >/=70%). Patients were followed for an average of 2.7 years (range 1.5 to 4.0 years). Patients averaged 65 years of age; 77% were men; and 110 (11.2%) died during follow-up. CRP levels were significantly elevated in nonsurvivors compared with survivors (mean CRP 3.1 mg/dL versus 1.5 mg/dL, P:=0.003). After controlling for all known baseline variables, the 2nd and 3rd tertiles of CRP compared with the 1st produced a Cox hazard ratio (HR) for mortality of 2.4 (P:=0.001). Of the 3 infectious markers tested, only seropositivity to CMV (HR=1.9, P:<0.05) was predictive of mortality. The majority of mortality risk associated with elevated CRP or CMV seropositivity occurred when both risk factors were present (P: for trend <0.0001). Other independent predictors of increased risk of mortality were age (HR=1.07 per year, P:<0.0001), left ventricular ejection fraction (HR=0.97 per percent, P:<0.0001), and diabetes mellitus (HR=1.7, P:=0.02). CONCLUSIONS: CMV seropositivity and elevated CRP, especially when in combination, are strong, independent predictors of mortality in patients with CAD. This suggests an interesting hypothesis that a chronic, smoldering infection (CMV) might have the capacity to accelerate the atherothrombotic process. (+info)Naturally occurring lesions of the uterine tube in sheep and serologic evidence of exposure to Chlamydophila abortus. (3/356)
The uterine tubes from 405 ewes, collected at an abattoir, were assessed grossly and microscopically for abnormalities that correlated with serological evidence of exposure to Chlamydophila abortus. Gross lesions were found in 41 ewes and 86 had microscopic lesions. Enzyme immunoassay (EIA) of serum was used as an indication of exposure of individual ewes to C. abortus; 52 were found to be positive. Chi-squared analysis indicated no association between EIA-positive animals and lesions of the uterine tube. (+info)Unstable atherosclerotic plaques contain T-cells that respond to Chlamydia pneumoniae. (4/356)
OBJECTIVE: Atherosclerotic lesions are characterized by an immune mediated chronic inflammation. Seroepidemiological studies support a relationship between atherosclerotic disease and infection with C. pneumoniae; an association further endorsed by immunocytochemical and DNA directed studies. However, the question arises whether C. pneumoniae acts as a causal antigen, or is merely a bystander. For this reason we have analyzed the T lymphocyte population of carotid atherosclerotic plaques of symptomatic patients for their response against C. pneumoniae. METHODS: T cell lines were generated from carotid endarterectomy tissues obtained from eight patients with symptomatic disease. The response of these T cell lines against C. pneumoniae elementary bodies was analyzed by 3H-thymidine incorporation. T cell clones were generated by limiting dilution from the cell lines of three patients and tested for antigen specificity in the same manner. Furthermore, cytokine profiles (Th1/Th0/Th2) were established by measuring the production of IFN-gamma and IL-4. RESULTS: Of the eight T-cell lines five responded to C. pneumoniae. Eighteen of 69 CD4-positive clones, generated from three patients with a positive T cell lines response, responded to C. pneumoniae also. The majority (17/18, 96%) of these clones showed a Th1 cytokine profile. CONCLUSION: These results show that in a subpopulation of symptomatic patients C. pneumoniae can activate T cells within atherosclerotic plaques suggesting that a C. pneumoniae enhanced proinflammatory Th1 response contributes to plaque destabilization in these patients. (+info)Cardiovascular infection by Chlamydia pneumoniae is not related to apolipoprotein E genotype. (5/356)
Chlamydia pneumoniae is detectable in the blood vessels of patients suffering from arteriosclerosis. Risk for arteriosclerosis is modulated by the apolipoprotein E (apoE) allele. We assessed the significance of the apoE genotype as a risk factor for vascular C. pneumoniae infection by determining the genotype of 30 coronary heart disease patients with PCR-proven C. pneumoniae infection of coronary artery tissue. The apoE genotype is not distinctly associated with an increased risk for vascular C. pneumoniae infection. (+info)Atherosclerosis in apoE knockout mice infected with multiple pathogens. (6/356)
Cytomegalovirus (CMV) and Chlamydia pneumoniae (CP) possibly contribute to atherosclerosis. Murine CMV (MCMV) and CP increase lesion size in apoE knockout mice. In this study, apoE knockout mice were infected with MCMV and CP to determine whether infection with multiple pathogens increases lesion size to a greater extent than either pathogen alone and whether infection with MCMV changes serum cytokine levels in a manner that could increase lesion development. One group of mice received MCMV at 2 weeks of age, followed by 2 doses of CP at 6 and 8 weeks of age. Additional groups received only MCMV or CP. Animals were killed at 16 weeks of age to determine lesion area. Infection with MCMV alone, CP alone, and both MCMV and CP increased lesion size 84% (P<.001), 70% (P<.0001), and 45% (P<.01), respectively. The MCMV-induced increase in circulating levels of interferon-gamma may have contributed to this increase. (+info)Effect of azithromycin on murine arteriosclerosis exacerbated by Chlamydia pneumoniae. (7/356)
Chlamydia pneumoniae infection can exacerbate atherosclerosis in animals. To test the hypothesis that antibiotic therapy inhibits the atherogenic effects of C. pneumoniae infection, 10-week-old apolipoprotein E (ApoE) null mice were infected with C. pneumoniae or placebo, were treated for 2 weeks after infection with azithromycin or placebo, and were killed at 20 weeks of age. Infection did not affect the size of the aortic lesion, and antibiotic treatment had no effect. Another group of mice, 12-week-old ApoE mice, were infected with C. pneumoniae or placebo, were treated for 2 weeks after infection with azithromycin or placebo, and were killed at 26 weeks of age. C. pneumoniae infection increased the size of the lesion in infected mice, but azithromycin did not reduce the size of the aortic lesion in infected mice. Therefore, immediate therapy of acute infection may be necessary to prevent the proatherogenic effects of C. pneumoniae infection. (+info)Chlamydia pneumoniae and the lung. (8/356)
Chlamydia pneumoniae is a frequently occurring respiratory pathogen affecting all age groups. It may cause 5-20% of community-acquired pneumonias in adults and children. The organism has also been implicated as an infectious trigger for asthma. Furthermore, new studies suggest that it may play a role in the pathogenesis of several chronic diseases including atherosclerosis. However, despite the growing significance of C. pneumoniae as a pathogen, progress is hampered by the lack of standardized diagnostic methods including serology and polymerase chain reaction. This makes it practically impossible for the practitioner to make a specific microbiological diagnosis. The lack of standardized methods has also had an adverse effect on treatment trials. The dependence on serology for diagnosis in treatment studies has generated some questionable results. Unless cultures are performed, microbiological efficacy cannot be assessed and it may never be possible to survey for or document the emergence of resistance. (+info)Some common types of Chlamydophila infections include:
1. Pneumonia: Chlamydophila pneumoniae can cause pneumonia, which is an inflammation of the lungs that can lead to fever, cough, chest pain, and difficulty breathing.
2. Trachoma: Chlamydia trachomatis can cause trachoma, a highly contagious eye infection that can lead to blindness if left untreated.
3. Pelvic inflammatory disease (PID): Chlamydia trachomatis and Chlamydia psittaci can cause PID, an infection of the female reproductive organs that can lead to chronic pelvic pain, infertility, and ectopic pregnancy.
4. Urinary tract infections (UTIs): Chlamydia trachomatis and Chlamydia caviae can cause UTIs, which are infections of the urinary tract that can lead to symptoms such as burning during urination and frequent urination.
5. Rectal infections: Chlamydia trachomatis and Chlamydia psittaci can cause rectal infections, which can lead to symptoms such as rectal pain, bleeding, and discharge.
Chlamydophila infections are typically treated with antibiotics, and early treatment can help prevent long-term complications and reduce the risk of transmission to others. It is important to practice safe sex and good hygiene to prevent the spread of these infections.
Psittacosis is a zoonotic disease, meaning it can be transmitted between animals and humans. It is important to take precautions when handling birds or their droppings to avoid infection. Treatment of psittacosis typically involves antibiotics, and early diagnosis and treatment can help prevent complications and improve outcomes.
Psittacosis is a rare disease, but it is important for veterinarians, avian specialists, and other professionals who work with birds to be aware of the risk of transmission and take appropriate precautions to protect themselves and others.
Definition:
Veterinary abortion refers to the intentional termination of a pregnancy in an animal, typically a farm or domesticated animal such as a dog, cat, horse, cow, or pig. The procedure is performed by a veterinarian and is usually done for reasons such as unwanted breeding, disease or genetic disorders in the fetus, or to prevent overpopulation of certain species.
Types of Veterinary Abortion:
1. Spontaneous Abortion (Miscarriage): This occurs naturally when the pregnancy is terminated by natural causes such as infection or trauma.
2. Induced Abortion: This is performed by a veterinarian using various methods such as injection of drugs or surgical procedures to terminate the pregnancy.
Methods of Veterinary Abortion:
1. Drug-induced abortion: This method involves administering medication to the animal to cause uterine contractions and expulsion of the fetus.
2. Surgical abortion: This method involves surgical intervention to remove the fetus from the uterus, usually through a small incision in the abdomen.
3. Non-surgical abortion: This method uses a device to remove the fetus from the uterus without making an incision.
Complications and Risks of Veterinary Abortion:
1. Infection: As with any surgical procedure, there is a risk of infection.
2. Hemorrhage: Excessive bleeding can occur during or after the procedure.
3. Uterine rupture: In rare cases, the uterus may rupture during the procedure.
4. Incomplete abortion: In some cases, not all of the fetus may be removed, leading to complications later on.
5. Scarring: Scars may form in the uterus or abdomen after the procedure, which can lead to reproductive problems in the future.
Prevention of Unwanted Pregnancies in Animals:
1. Spaying/neutering: This is the most effective way to prevent unwanted pregnancies in animals.
2. Breeding management: Proper breeding management, including selecting healthy and fertile breeding animals, can help reduce the risk of unwanted pregnancies.
3. Use of contraceptives: Hormonal contraceptives, such as injection or implants, can be used in some species to prevent pregnancy.
4. Behavioral management: In some cases, behavioral management techniques, such as separation or rehoming of animals, may be necessary to prevent unwanted breeding.
Ethical Considerations of Veterinary Abortion:
1. Animal welfare: The procedure should only be performed when necessary and with the intention of improving the animal's welfare.
2. Owner consent: Owners must provide informed consent before the procedure can be performed.
3. Veterinarian expertise: The procedure should only be performed by a licensed veterinarian with experience in the procedure.
4. Alternative options: All alternative options, such as spaying/neutering or rehoming, should be considered before performing an abortion.
Conclusion:
Veterinary abortion is a complex issue that requires careful consideration of ethical and practical factors. While it may be necessary in some cases to prevent the suffering of unwanted litters, it is important to approach the procedure with caution and respect for animal welfare. Owners must provide informed consent, and the procedure should only be performed by a licensed veterinarian with experience in the procedure. Alternative options, such as spaying/neutering or rehoming, should also be considered before performing an abortion. Ultimately, the decision to perform a veterinary abortion should be made with the intention of improving the animal's welfare and quality of life.
Chlamydiaceae infections are a group of bacterial infections caused by the bacterium Chlamydia. These infections can affect various parts of the body, including the respiratory tract, genitourinary tract, and eyes.

Diagnosis of Chlamydiaceae Infections:
Diagnosis of Chlamydiaceae infections is typically made through a combination of physical examination, medical history, and laboratory tests. Laboratory tests may include:
1. PCR (polymerase chain reaction) test: A test that detects the presence of Chlamydia trachomatis DNA in a sample of cells or tissue.
2. NAAT (nucleic acid amplification test): A test that detects the presence of Chlamydia trachomatis RNA or DNA in a sample of cells or tissue.
3. Culture: A test that grows Chlamydia trachomatis bacteria from a sample of cells or tissue.
4. Immunoassay: A test that detects the presence of antibodies against Chlamydia trachomatis in the blood or other body fluids.
Treatment of Chlamydiaceae Infections:
Chlamydiaceae infections are typically treated with antibiotics. The choice of antibiotic depends on the severity and location of the infection, as well as the patient's age, health status, and any allergies they may have. Common antibiotics used to treat Chlamydiaceae infections include:
1. Azithromycin (Z-Pak)
2. Doxycycline
3. Erythromycin
4. Levofloxacin (Levaquin)
5. Ofloxacin (Floxin)
6. Ceftriaxone (Rocephin)
7. Ciprofloxacin (Cipro)
It is important to note that antibiotics should only be prescribed by a healthcare professional, and the patient should complete the full course of treatment as directed, even if symptoms resolve before finishing the medication. Untreated Chlamydiaceae infections can lead to serious complications, such as infertility, ectopic pregnancy, and pelvic inflammatory disease.
Prevention of Chlamydiaceae Infections:
To prevent Chlamydiaceae infections, it is important to practice safe sex, including:
1. Using condoms or dental dams for all sexual activities
2. Avoiding sexual contact with anyone who has a Chlamydiaceae infection
3. Getting regularly tested for Chlamydiaceae infections if you are sexually active
4. Informing any sexual partners if you have a Chlamydiaceae infection
5. Using a new condom or dental dam for each sexual activity
6. Avoiding sharing of sex toys
7. Washing your hands after sexual activity
8. Getting vaccinated against Chlamydia trachomatis if you are at high risk for infection.
It is also important to note that Chlamydiaceae infections can be spread from mother to child during pregnancy and childbirth, so it is important for pregnant women to be screened and treated for Chlamydiaceae infections if they are positive.
In conclusion, Chlamydiaceae infections are a common cause of genitourinary tract infections and can have serious complications if left untreated. It is important to practice safe sex, get regularly tested, and seek medical attention if symptoms persist or worsen over time. With proper treatment and prevention methods, Chlamydiaceae infections can be effectively managed and the risk of complications reduced.

The most common bacteria that cause pneumonia are Streptococcus pneumoniae (also known as pneumococcus), Haemophilus influenzae, and Staphylococcus aureus. These bacteria can infect the lungs through various routes, including respiratory droplets, contaminated food or water, or direct contact with an infected person.
Symptoms of pneumonia may include cough, fever, chills, shortness of breath, and chest pain. In severe cases, pneumonia can lead to serious complications such as respiratory failure, sepsis, and death.
Diagnosis of pneumonia typically involves a physical examination, medical history, and diagnostic tests such as chest X-rays or blood cultures. Treatment typically involves antibiotics to eliminate the infection, as well as supportive care to manage symptoms and prevent complications. Vaccines are also available to protect against certain types of bacterial pneumonia, particularly in children and older adults.
Preventative measures for bacterial pneumonia include:
* Getting vaccinated against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib)
* Practicing good hygiene, such as washing hands regularly and covering the mouth and nose when coughing or sneezing
* Avoiding close contact with people who are sick
* Staying hydrated and getting enough rest
* Quitting smoking, if applicable
* Managing underlying medical conditions, such as diabetes or heart disease
It is important to seek medical attention promptly if symptoms of pneumonia develop, particularly in high-risk populations. Early diagnosis and treatment can help prevent serious complications and improve outcomes for patients with bacterial pneumonia.

10. Vitamin deficiencies: Deficiencies in vitamins such as vitamin A, D, or E can cause a range of health problems in goats, including skin conditions, poor appetite, and weakness.
Goat diseases can be diagnosed through physical examination, laboratory tests, and imaging studies. Treatment depends on the specific disease and may involve antibiotics, antiviral medications, or supportive care such as fluid therapy and nutritional supplements. Prevention is key in managing goat diseases, and this includes maintaining good hygiene, providing clean water and a balanced diet, and vaccinating goats against common diseases.
Symptoms include:
* Redness and swelling of the conjunctiva
* Discharge (pus) in the eye
* Itching or burning sensation in the eye
* Crusting of the eyelids
* Blurred vision
* Sensitivity to light
Diagnosis is usually made based on symptoms and physical examination, but may require laboratory testing to rule out other causes.
Treatment typically includes antibiotic eye drops or ointments, which can help to clear up the infection within a few days. In severe cases, oral antibiotics may be prescribed. Anti-inflammatory medications may also be used to reduce swelling and discomfort. Good hygiene practices, such as washing hands frequently and avoiding close contact with others, can help to prevent the spread of the infection.
Prognosis is generally good, but complications can include corneal ulcers, which can lead to vision loss if left untreated. Recurrent conjunctivitis may occur in some individuals, particularly those with weakened immune systems or other underlying medical conditions.
Prevention includes good hygiene practices, avoiding close contact with others, and avoiding sharing personal items such as towels or makeup. Vaccination against streptococcal infections can also help to prevent conjunctivitis caused by this type of bacteria.
The symptoms of chlamydia infections can vary depending on the location of the infection. In genital infections, symptoms may include:

In eye infections, symptoms can include:
* Redness and swelling of the eye
* Discharge from the eye
* Pain or sensitivity to light
In respiratory infections, symptoms may include:
* Cough
* Fever
* Shortness of breath or wheezing
If left untreated, chlamydia infections can lead to serious complications, such as pelvic inflammatory disease (PID) in women and epididymitis in men. Chlamydia infections can also increase the risk of infertility and other long-term health problems.
Chlamydia infections are typically diagnosed through a physical examination, medical history, and laboratory tests such as a nucleic acid amplification test (NAAT) or a culture test. Treatment for chlamydia infections typically involves antibiotics, which can effectively cure the infection. It is important to note that sexual partners of someone with a chlamydia infection should also be tested and treated, as they may also have the infection.
Prevention methods for chlamydia infections include safe sex practices such as using condoms and dental dams, as well as regular screening and testing for the infection. It is important to note that chlamydia infections can be asymptomatic, so regular testing is crucial for early detection and treatment.
In conclusion, chlamydia is a common sexually transmitted bacterial infection that can cause serious complications if left untreated. Early detection and treatment are key to preventing long-term health problems and the spread of the infection. Safe sex practices and regular screening are also important for preventing chlamydia infections.
Some common types of eye infections include:
1. Conjunctivitis - a highly contagious infection of the conjunctiva, which is the thin membrane that covers the white part of the eye and the inside of the eyelids. It can be caused by bacteria or virus and is commonly known as pink eye.
2. Keratitis - an inflammation of the cornea, which is the clear dome-shaped surface at the front of the eye. It can be caused by bacteria, virus or fungi.
3. Uveitis - an inflammation of the uvea, which is the layer of tissue between the sclera and retina. It can cause pain, sensitivity to light and blurred vision.
4. Endophthalmitis - a severe infection inside the eye that can cause damage to the lens, retina and other structures. It is usually caused by bacteria or fungi and can be a complication of cataract surgery or other eye procedures.
5. Dacryocystitis - an inflammation of the tear ducts and sac that can cause pain, redness and swelling in the eyelid. It is usually caused by bacteria.
Eye infections can be diagnosed through a comprehensive eye exam, which may include a visual acuity test, dilated eye exam, tonometry and imaging tests such as ultrasound or CT scans. Treatment depends on the type of infection and severity of the condition, and may involve antibiotic or antiviral medication, anti-inflammatory medication or surgery. It is important to seek medical attention if symptoms persist or worsen over time, as untreated eye infections can lead to complications such as vision loss, corneal scarring and even blindness.
There are several different types of conjunctivitis, including:
1. Allergic conjunctivitis: This type is caused by an allergic reaction and is more common in people who have a history of allergies.
2. Bacterial conjunctivitis: This type is caused by a bacterial infection and is often accompanied by a thick discharge and redness of the eye.
3. Viral conjunctivitis: This type is caused by a viral infection and is highly contagious.
4. Chemical conjunctivitis: This type is caused by exposure to chemicals or foreign objects, such as smoke, dust, or pollen.
5. Irritant conjunctivitis: This type is caused by exposure to irritants such as chemicals or foreign objects.
Symptoms of conjunctivitis can include redness and discharge of the eye, itching, burning, and tearing. Treatment typically involves antibiotic eye drops or ointments for bacterial conjunctivitis, anti-inflammatory medication for allergic conjunctivitis, and viral conjunctivitis is usually self-limiting and requires supportive care only.
It's important to note that conjunctivitis can be highly contagious, so it's important to practice good hygiene, such as washing your hands frequently, avoiding sharing personal items like towels or makeup, and not touching the eyes. If you suspect you have conjunctivitis, it's important to see a healthcare professional for proper diagnosis and treatment.
Some common types of eye neoplasms include:
1. Uveal melanoma: This is a malignant tumor that develops in the uvea, the middle layer of the eye. It is the most common primary intraocular cancer in adults and can spread to other parts of the body if left untreated.
2. Retinoblastoma: This is a rare type of cancer that affects children and develops in the retina. It is usually diagnosed before the age of 5 and is highly treatable with surgery, chemotherapy, and radiation therapy.
3. Conjunctival melanoma: This is a malignant tumor that develops in the conjunctiva, the thin membrane that covers the white part of the eye. It is more common in older adults and can be treated with surgery and/or radiation therapy.
4. Ocular sarcomas: These are rare types of cancer that develop in the eye tissues, including the retina, optic nerve, and uvea. They can be benign or malignant and may require surgical removal or radiation therapy.
5. Secondary intraocular tumors: These are tumors that metastasize (spread) to the eye from other parts of the body, such as breast cancer or lung cancer.
The symptoms of eye neoplasms can vary depending on their location and type, but may include:
* Blurred vision
* Eye pain or discomfort
* Redness or inflammation in the eye
* Sensitivity to light
* Floaters (specks or cobwebs in vision)
* Flashes of light
* Abnormal pupil size or shape
Early detection and treatment of eye neoplasms are important to preserve vision and prevent complications. Diagnosis is typically made through a combination of physical examination, imaging tests such as ultrasound or MRI, and biopsy (removing a small sample of tissue for examination under a microscope). Treatment options may include:
* Surgery to remove the tumor
* Radiation therapy to kill cancer cells
* Chemotherapy to destroy cancer cells with medication
* Observation and monitoring if the tumor is slow-growing or benign
It's important to seek medical attention if you experience any unusual symptoms in your eye, as early detection and treatment can improve outcomes.
