What Antibiotics Treat Pneumonia In Adults

What Are The Symptoms Of Pneumonia

Antibiotics for pneumonia part 1

Cough is a common symptom. You may also feel generally unwell and have a high temperature . Other symptoms you may notice include:

  • Loss of appetite

All these symptoms are also seen in flu so it is sometimes difficult to diagnose pneumonia in the early stages. See the separate leaflet called Influenza and Flu-like Illness for further details.

Coughing up a lot of phlegm is more likely to happen in pneumonia than in flu. The phlegm may become yellow-coloured or green-coloured. It may be streaked with blood or you may cough up more significant amounts of blood.

You may become short of breath, start breathing faster than normal and develop a tight chest. A sharp pain in the side of the chest may develop if the infection involves the pleura. The pleura is the membrane between the lung and the chest wall. A doctor may hear crackles when listening to your chest with a stethoscope.

How Is Bacterial Pneumonia Treated

Bacterial pneumonia can be treated with antibiotics, which usually help people feel better within a few days to a week.

People who are very old, very young, have shortness of breath, or have a high fever may need to be admitted to the hospital for intravenous antibiotics. If you need to go to the hospital, your doctor may do cultures from sputum or blood tests to identify and target the exact bacteria.

People with more severe cases of bacterial pneumonia may be treated with oxygen, intravenous fluids, and breathing treatments to ease symptoms.

Antibiotic Resistance Of The Major Causative Bacteria Of Community

Resistance against ampicillin due β-lactamase production is common in H. influenzae. In a domestic study that analysed 544 bacterial strains, the antibiotic resistance against ampicillin, cefuroxime, clarithromycin, cefaclor, and amoxicillin/clavulanate was 58.5%, 23.3%, 18.7%, 17.0%, and 10.4%, respectively . This study did not identify bacterial strains that are resistant to levofloxacin and cefotaxime. In another study that analysed 229 bacterial strains, the antibiotic resistance against ampicillin high at 58.1%, and that against cefaclor, clarithromycin, amoxicillin/clavulanate, cefixime, and levofloxacin was 41.4%, 25.8%, 13.5%, 10.9%, and 1.3%, respectively .

Not many studies have analysed the antibiotic susceptibility of M. pneumoniae in Korea. In a study that examined M. pneumoniae isolated from respiratory organ samples of pediatric patients in 2000-2011, genes related to macrolide resistance was detected in 31.4% of the samples, and this rate was reported to increase every year . In another study using respiratory organ samples from pediatric patients, genes related to macrolide resistance were found in 17.6% of the samples of M. pneumoniae . Although the ratio of methicillin-resistant S. aureus in community-acquired S. aureus infection has been increasing in Korea, systematic research on the role of MRSA in community-acquired pneumonia is lacking .

How Is Fungal Pneumonia Treated

If the course of the pneumonia is slow and your chest X-ray looks unusual, you may have fungal pneumonia. These conditions can be diagnosed with a blood test that shows your body is making antibodies to the fungus.

More than 10 types of fungi can cause fungal pneumonia, which is more common in people with weakened immune systems.

Several antifungal drugs serve as treatment for pneumonia and can be administered either orally or intravenously.

How Are Pneumonia Complications Treated

Antimicrobial Therapy for Community

Complications may be more common in pneumonia that starts after stomach contents are inhaled into the lungs, a type of condition called aspiration pneumonia.

Another dangerous variation is necrotizing pneumonia, a bacterial pneumonia that can result from a large number of pathogens, including staphylococcus.

Complicated pneumonias such as these may result in respiratory failure, which requires assisted breathing with a machine called a ventilator.

In rare but severe cases, a pocket of pus called a lung abscess can form inside or around the lung due to causes that include aspiration and bacterial or fungal infections.

If you have complicated pneumonia, you may need to undergo a procedure to drain the lung or remove diseased lung tissue. Your doctor may refer to this procedure as “lung scraping.”

Which Vaccines Should Be Administered To Elderly Patients In Order To Prevent Cap

Vaccination remains the primary preventive strategy for CAP in the elderly. Guidelines recommend immunization against both influenza virus and S. pneumoniae in patients above the age of 65. Nevertheless, both vaccinations are substantially underused in this vulnerable population.

Recent meta-analyses provide evidence supporting the recommendation of pneumococcal polysaccharide vaccine to prevent invasive pneumococcal disease in adults, but, with regard to adults with chronic illness, do not find compelling evidence to support the routine use of PPV to prevent all-cause pneumonia or mortality . However, the 23-valent vaccine prevented pneumococcal pneumonia and reduced mortality due to pneumococcal pneumonia in nursing-home residents in a randomized trial . Moreover, in a matched casecontrol study in patients aged 65 years and hospitalized with CAP, Domínguez and colleagues found an effectiveness of 23.6% for the PPV for preventing hospitalizations due to pneumonia .

Are Side Effects Associated With The Pneumonia Vaccine

Side effects of PCV13 in children include drowsiness, temporary loss of appetite, or redness, swelling, or tenderness where the shot was given. Mild fever and irritability are other common side effects. Adults receiving pneumococcal vaccines have reported pain, redness, rash, and swelling where the shot was given also mild fever, fatigue, headache, chills, or muscle pain.

Any type of vaccine has the potential to cause an allergic reaction, which can be severe, but this side effect is rare. This would happen within minutes to a few hours after receiving the vaccine.

What Antibiotics Treat Pneumonia In Cats

What Antibiotics Treat Pneumonia In Cats? In cases where it truly is difficult to know whether aspiration or bronchopneumonia is more likely, airway sampling either in the form of ETW or BAL would be recommended. The most commonly prescribed antibiotics for pneumonia include amoxicillin/clavulanate, doxycycline, and fluoroquinolones.

Compounding the situation is the fact that many of these cats may be unvaccinated or under-vaccinated, which also means they have little to no protection against many of the agents causing respiratory infections in cats. Remember, antibiotics do NOT treat viral infections whatsoever, so for simple, routine upper respiratory infections in cats, they are not indicated. We consider upper respiratory infections in cats to be very contagious, and it is not uncommon for a normal-looking kitten to be adopted from a shelter, only to start sneezing within a few days, followed shortly by all of the other cats in the house. If you are bringing home a new cat that may be infected, there are a few things you can do to try to slow the spread of upper respiratory infections to the other cats in your home.

What Is Walking Pneumonia

Walking pneumonia is a mild form of pneumonia . This non-medical term has become a popular description because you may feel well enough to be walking around, carrying out your daily tasks and not even realize you have pneumonia.

Most of the time, walking pneumonia is caused by an atypical bacteria called Mycoplasma pneumoniae, which can live and grow in the nose, throat, windpipe and lungs . It can be treated with antibiotics.

Scientists call walking pneumonia caused by mycoplasma atypical because of the unique features of the bacteria itself. Several factors that make it atypical include:

  • Milder symptoms
  • Natural resistance to medicines that would normally treat bacterial infections
  • Often mistaken for a virus because they lack the typical cell structure of other bacteria

Questions To Ask Your Doctor

  • I have a chronic condition. Am I at higher risk for pneumonia?
  • Do I have bacterial, viral, or fungal pneumonia? Whats the best treatment?
  • Am I contagious?
  • How serious is my pneumonia? Will I need to be hospitalized?
  • What can I do at home to help relieve my symptoms?
  • What are the possible complications of pneumonia? How will I know if Im developing complications?
  • What should I do if my symptoms dont respond to treatment or get worse?
  • Do we need to schedule a follow-up exam?
  • Do I need any vaccines?

What Treatment Should Elderly Patients With Cap Receive

Antimicrobials are the cornerstone of therapy for CAP in any population, including the elderly. The most recently published clinical practice guidelines for CAP do not recommend different treatments for elderly patients .

According to the IDSA/ATS guidelines, in the outpatient setting, the recommended empirical treatment is a macrolide for previously healthy patients who have not used antimicrobials within the previous 3 months. However, in some countries macrolide-resistant S. pneumoniae are frequent . A respiratory fluoroquinolone or a beta-lactam plus a macrolide are recommended for patients with comorbidities. In hospitalized patients with nonsevere CAP, the recommendation is a respiratory fluoroquinolone or a beta-lactam plus a macrolide. In severe CAP, a combination of antibiotics is usually recommended. A beta-lactam plus either azithromycin or a respiratory fluoroquinolone are preferred. In patients with predisposing factors for P. aeruginosa or other Gram-negative bacilli an antipneumococcal, antipseudomonal beta-lactam plus either a quinolone or an aminoglycoside and azithromycin should be considered . If MRSA is considered as a possible causative organism, guidelines recommend adding vancomycin or linezolid.

. Similarly, it is asked, how long do you take IV antibiotics for pneumonia?

Patients were initially treated with three days of IV antibiotics and, when clinically stable, were assigned either to oral antibiotics to complete a total course of 10 days or to a standard regimen of 7 days of IV antibiotics.

Also Know, what is the first line treatment for pneumonia? The Pneumonia Severity Index should be used to assist in decisions regarding hospitalization of patients with CAP. The initial treatment of CAP is empiric, and macrolides or doxycycline should be used in most patients.

Also know, what is the best antibiotic to treat pneumonia?

Macrolide antibiotics: Macrolide drugs are the preferred treatment for children and adults. Macrolides include azithromycin and clarithromycin .

What is the drug of choice for pneumonia?

Levofloxacin is rapidly becoming a popular choice in pneumonia this agent is a fluoroquinolone used to treat CAP caused by S aureus, S pneumoniae , H influenzae, H parainfluenzae, Klebsiella pneumoniae, M catarrhalis, C pneumoniae, Legionella pneumophila, or M pneumoniae.

How Do You Diagnose Pneumonia

  • Symptoms – a doctor will suspect pneumonia from asking about your symptoms and how you are feeling. They may also ask about your medical history and that of your family. They will be interested in whether you smoke, how much and for how long. The examination may include checking your temperature. Sometimes your doctor will check how much oxygen is circulating around your body. This is done with a small device that sits on the end of your finger. The doctor will listen to your chest, so they may want you to lift or take off your top. If you want a chaperone during the examination, the doctor will arrange one. If you have asthma, they may ask you to check your peak flow measurement. They will listen to your chest with a stethoscope. Tapping your chest over the infected lung is also sometimes performed. This is called percussion. An area of infected lung may sound dull.
  • X-ray – a chest X-ray may be required to confirm the diagnosis and to see how serious the infection is.
  • Other tests – these tests are usually carried out if you need to be admitted to hospital. They include sending a sample of phlegm for analysis and blood cultures to check if the infection has spread to your blood.

Complications Caused By Pneumonia

Pneumonia can sometimes have complications. They include:

  • pleurisy where the pleura, the thin linings between your lungs and ribcage, become inflamed, leading to chest pain. If you have pleurisy, you are more likely to develop fluid on the lungs.
  • fluid on the lungs – about 1 in 10 people with pneumonia develop fluid around the lung, called a pleural effusion which can become infected. This may require a sample of the fluid to be taken by inserting a needle between the ribs under local anaesthetic, and if infected is likely to need a longer course of antibiotics. Occasionally, a tube is inserted into the lung to remove fluid as well.
  • a lung abscess a rare complication thats mostly seen in people with a serious pre-existing illness or history of alcohol misuse.
  • blood poisoning, also called septicaemia – this is where infection spreads from the lungs to the blood stream. This can cause low blood pressure and a severe illness that might need intensive care treatment.
  • respiratory failure this is where pneumonia causes low levels of oxygen in the blood even in people given oxygen. This might also require intensive care treatment.

The vast majority of people recover from pneumonia and return to good health. However, pneumonia can be very serious and some people with severe pneumonia dont survive, despite the best available care. Those who are elderly or have other health problems are most at risk of severe or fatal pneumonia.

Data Collection And Evaluation

All patients were assessed on hospital admission and followed during hospital stay until discharge, according to a standardised data sheet. The following parameters were evaluated: date of presentation age sex weight smoking habits comorbidities mode of hospital admission residence in nursing home duration of symptoms clinical symptoms blood gas analysis chest radiography laboratory parameters and intensive care unit admission and/or mechanical ventilation. The following three end-points were defined: hospital discharge, conclusion of the in-patient treatment due to CAP and death. For comparison of pneumonia severity within groups, the Pneumonia Severity Index and CURB-65 score were calculated for each patient on admission .

Is There A Vaccine For Pneumonia

Antibiotics after pneumonia: Study finds overprescribing at hospital discharge

There isnt a vaccine for all types of pneumonia, but 2 vaccines are available. These help prevent pneumonia caused by pneumococcal bacteria. The first is recommended for all children younger than 5 years of age. The second is recommended for anyone age 2 or older who is at increased risk for pneumonia. Getting the pneumonia vaccine is especially important if you:

  • Are 65 years of age or older.
  • Smoke.
  • Have certain chronic conditions, such as asthma, lung disease, diabetes, heart disease, sickle cell disease, or cirrhosis.
  • Have a weakened immune system because of HIV/AIDS, kidney failure, a damaged or removed spleen, a recent organ transplant, or receiving chemotherapy.
  • Have cochlear implants .

The pneumococcal vaccines cant prevent all cases of pneumonia. But they can make it less likely that people who are at risk will experience the severe, and possibly life-threatening, complications of pneumonia.

Treatment Of Pneumonia After Antibiotics

Treatment of pneumonia after antibiotics can be the reason for the selection of ineffective drugs or if the intake of antibacterial agents is not taken properly – an incorrect dosage, a violation of the regimen. In normal course, antibiotics are taken to normalize the temperature and then after 3 more days. In severe cases of pneumonia, treatment may take up to 4-6 weeks. If during this period the positive dynamics of the disease is not fixed, then the cause is in the wrong antibacterial treatment. In this case, a second analysis is performed on the bacteria, after which a course of correct antibacterial therapy is conducted. After full recovery and positive results of radiography, spa treatment, smoking cessation, and increased vitamin nutrition are indicated.

In the additional treatment with antibiotics after pneumonia, the patient may need to:

  • Wrongly chosen antibiotic for treatment.
  • Frequent change of antibiotics.

Also, antibiotic treatment after pneumonia may be necessary in the event of a recurrence of the disease. The reason for this – long-term treatment with antibiotics, depressing the defenses of the body. Also, a similar result arises from self-medication and uncontrolled administration of antibiotics at unidentified doses.

Atypical Pathogens And Their Resistance

Globally, Mycoplasma pneumoniae, Legionella pneumophila, and Chlamydophila pneumoniae are atypical bacteria commonly involved in CABP. Atypical pathogens such as Mycoplasma and Legionella constitute up to 20% of etiological agents in hospitalized patients with CABP. Thus, it is imperative that empirical antibiotic coverage should include atypical pathogens. However, a 2012 Cochrane systematic review of 28 randomized controlled trials evaluating empirical coverage of atypical pathogens reported no difference in mortality between the atypical arm and the nonatypical arm . Interestingly, a nonsignificant trend toward clinical success and a significant advantage to bacteriological eradication were Reported in atypical arm. Emergence of resistance is an important factor that makes the treatment difficult. Macrolide-resistant M. pneumoniae have been reported and are associated with longer duration of antibiotic therapy and longer time for the resolution of fever. Given these results, atypical coverage should be the part of initial empirical therapy to improve the clinical success rate.
