Doxycycline – Mechanism, precautions, side effects & uses

Economic pressures have accentuated the focus on reducing health care costs and utilizing resources while maintaining or improving quality of care.31 These pressures are exacerbated by the growing resistance of S. pneumoniae to penicillin.31,32 This pattern of resistance increases the cost of treatment because of prolonged hospitalization, relapses, and the use of more expensive antibacterial agents.3337

It also is used to treat gonorrhea. Other penicillin-type antibiotics include ampicillin , piperacillin , and ticarcillin . These antibiotics stop bacteria from multiplying by preventing bacteria from forming the walls that surround them that are necessary to protect bacteria from their environment and to keep the contents of the bacterial cell together. Bacteria are unable survive without a cell wall. Amoxicillin is effective against many different bacterial strains including H. influenzae, E. coli, Pneumococci, N. gonorrhoea, Streptococci, and some strains of Staphylococci.

Doxycycline is a tetracycline antibiotic used for many different types of infections, including respiratory tract infections due to Hemophilus influenzae, Streptococcus pneumoniae, or Mycoplasma pneumoniae.

Types Of Antibiotics For Pneumonia

What are the uses of Doxycycline?

Pneumonia is a respiratory infection that affects the lower part of the respiratory system, primarily the lungs or the bronchi.

The bronchi are the air passages that connect the lungs to the windpipe.

Because pneumonia causes the air sacs in your lungs fill with pus and fluid, pneumonia can make it harder to take in oxygen and expel carbon dioxide.

Pneumonia is typically caused by a virus or bacterial infection.

Sometimes fungal infections can lead to pneumonia, but that is rarer, and typically occurs in people with weak immune systems due to other diseases.

Viral pneumonia will often resolve on its own, though it still frequently requires medical care for supportive treatment.

Sometimes pneumonia occurs during or after another viral illness, like the flu or a cold.

If your pneumonia is caused by a virus, antibiotics wont help unless there is also a secondary bacterial infection.

If you have bacterial pneumonia, you will need antibiotics to prevent complications and to help your body clear the infection.

Even with antibiotics, it can still take 4-6 weeks to recover from bacterial pneumonia.

Most bacterial pneumonia that is community-acquired comes from the bacteriaStreptococcus pneumoniae.

There are several different antibiotics are effective at treating this bacterial infection.

The following article is a part of conference coverage from the American College of Allergy, Asthma & Immunology 2021 Annual Scientific Meeting, being held virtually from November 4 to 8, 2021. The team at Pulmonology Advisor will be reporting on the latest news and research conducted by leading experts in the field. Check back for more from the ACAAI 2021 Annual Scientific Meeting.

The use of doxycycline therapy in patients with COVID-19 pneumonia is not associated with improved mortality rates, according to research findings being presented at the American College of Allergy, Asthma & Immunology 2021 Annual Scientific Meeting, November 4 to 8, in New Orleans, LA.

The researchers examined outcomes linked to doxycycline treatment in hospitalized patients with COVID-19 pneumonia through a retrospective, observational chart review of patients admitted to University Hospital in Brooklyn, NY, between March 2020 and June 2020, for COVID-19related symptoms.

A total of 478 charts of patients who were polymerase chain reactionpositive for SARS-CoV-2 infection were reviewed. Overall, 110 patients with COVID-19 were treated with doxycycline. Researchers extracted the following data points from all patient charts: the Charlson Comorbidity Index rate all medications administered to the patient National Early Warning Score -2 and length of hospital stay.

Why It Is Important To Do This Review

In clinical practice, use of corticosteroids for people with pneumonia remains variable. Current guidelines do not address corticosteroids in the standard management of people with CAP, HAP, HCAP, or VAP . An exception is the British guidelines, which state that “… steroids are not recommended in the routine treatment of high severity CAP” .

The 2011 version of this Cochrane Review showed that corticosteroids were beneficial for accelerating the time to resolution of symptoms with no effect on mortality for most people with pneumonia . Since then, several relatively large randomised controlled trials assessing the role of corticosteroids for people with pneumonia have been published. Combining data from all relevant trials may lead to more definitive conclusions, particularly whether the effects of corticosteroids could be patientspecific. Compiling all existing studies might allow for the assessment of corticosteroid effects for specific patient subgroups with pneumonia. For this update we revised the protocol, inclusion criteria, and analyses and reextracted all data. We have reported deviations from the original review, , in the section of this update.
