Based on the provided web search results and the patient’s case description, here’s a complete summary:
Patient case:
A 2-year-old boy presented to the emergency department (ED) with acute shortness of breath unresponsive to inhaled albuterol.He was afebrile, tachycardic, and tachypneic with an oxygen saturation of 90% in room air. His examination revealed subcostal and intercostal retractions,head bobbing,and diminished air movement with faint expiratory wheezes. Initial treatments included bilevel-positive airway pressure (BiPAP) for a severe asthma exacerbation. Chest X-ray was normal, but neck X-ray showed enlarged adenoids and tonsils.Laboratory results were unremarkable. He was later admitted to the pediatric intensive care unit (PICU) where his respiratory effort improved with heliox.
Mycoplasma pneumoniae Infection:
- Cause: Mycoplasma pneumoniae is a bacterium that causes acute respiratory illness, ranging from mild respiratory illness to severe pneumonia (Source: [3]).
- Common etiology: It is indeed one of the most common causes of community-acquired pneumonia (CAP) (source: [2]).
- Clinical presentation: The clinical presentation and manifestations can vary widely and affect all organs of the body (Source: [2]).
- Diagnosis and Reporting: Most laboratory reports are of infection in the respiratory tract (Source: [3]).
given the patient’s symptoms and the typical presentation of Mycoplasma pneumoniae infection, it is plausible that the patient’s severe respiratory distress could be attributed to this pathogen. Though,the normal chest X-ray and the absence of fever make the diagnosis less straightforward. Further diagnostic testing, such as a PCR test for mycoplasma pneumoniae, could confirm the infection.
Treatment:
- Initial Management: The patient was managed with BiPAP, racemic epinephrine, and heliox, which improved his respiratory effort.
- antibiotic Therapy: If Mycoplasma pneumoniae infection is confirmed, appropriate antibiotic therapy (e.g., macrolides or tetracyclines) should be initiated.
Follow-up:
- Monitoring: Close monitoring of the patient’s respiratory status and oxygen saturation is crucial.
- Further testing: Additional tests, such as a complete blood count with differential, may help in ruling out other infections or complications.

His breathing became more labored.
In the ED, he was febrile, tachycardic, and hypoxemic. His examination was notable for decreased breath sounds, worse over the left lower lobe, without wheezing or increased work of breathing. Lab workup was remarkable only for a C-reactive protein of 4 mg/dL. The chest x-ray showed focal left lower lobe and left lingular lobe airspace disease (figure 3).He was started on ampicillin-sulbactam intravenously and oxygen by nasal cannula. Over the next 24 hours, respiratory support was escalated to high-flow nasal cannula for increasing work of breathing and worsening hypoxemia. The chest x-ray was unchanged, and the chest ultrasound demonstrated a focal left lower lobe consolidation and trace left pleural effusion. Due to increasing oxygen needs and work of breathing, he was transferred to the PICU.
His physical examination on arrival at the PICU remained mostly focal to the left lower lobe but some rhonchi were noted bilaterally. Azithromycin was initiated, given the known high community prevalence. Multiplex respiratory PCR results were positive for M. pneumoniae. On day 3 of azithromycin treatment, he had an exacerbation of his underlying reactive airways requiring albuterol.

These patients may have a similar presentation of cough, shortness of breath, and hoarseness but with high fevers. In reported cases, M. pneumoniae is identified on PCR examination from a bronchial aspirate.12 Given the degree of swelling and airway narrowing in patient 1 described above, a laryngoscopy was deemed unsafe, so direct infectious studies from the larynx were not obtained.
Rashes have been described in cases of M. pneumoniae infection. More recently, in 2015, M. pneumoniae–induced rash and mucositis (MIRM) was described as a clinical entity.13 patient 2 had a bullous rash compatible with the vesiculobullous rash described in MIRM. However, he lacked mucosal involvement. Bullous rash secondary to M. pneumoniae has been rarely reported,14 but lack of mucosal involvement can lead to underdiagnosis. Severe cases of rash and mucositis require admission, and treatment modalities usually include steroids and intravenous immunoglobulin. Our patient was clinically stable, appeared well, and did not require hospital admission or treatment with immune modulators. He was treated only with an oral macrolide.
M. pneumoniae pneumonia (MPP) is commonly associated with atypical pneumonia, with diffuse, peribronchial, and perivascular interstitial infiltrates on chest x-ray. One-third of patients with MPP present with airspace consolidation. Other patterns include reticulonodular opacities or masslike opacities.15 Although MPP is often a mild and self-limited disease, approximately 12% of children with it progress to more severe lung disease, including pleural effusions, pulmonary embolism, and/or necrotizing pneumonia, as well as serious extrapulmonary complications.16 macrolides are the first-line treatment for this pathogen and are appropriate for treating children with more severe diseases. Although macrolide-resistant M. pneumoniae

The COVID-19 pandemic has significantly altered the landscape of infectious diseases, and the reemergence of mycoplasma pneumoniae infections in children and adolescents is a notable example. Recent studies and clinical observations have highlighted the resurgence of this pathogen, prompting healthcare professionals to maintain a heightened index of suspicion.
Changing Patterns of Respiratory Pathogens
The COVID-19 pandemic led to widespread public health measures, including social distancing and mask mandates, which initially reduced the incidence of respiratory infections. However, as these measures have eased, there has been a notable increase in Mycoplasma pneumoniae infections among children and adolescents. According to a recent report from the Centers for Disease Control and Prevention (CDC), the reemergence of Mycoplasma pneumoniae infections has been observed across the United States from 2018 to 2024.
Clinical Presentations and treatment
A pediatric case series described three atypical clinical presentations of Mycoplasma pneumoniae. These cases underscore the importance of early identification and appropriate treatment to prevent progression to more severe disease.While Mycoplasma pneumoniae infections are typically self-limiting, they can lead to complications such as pneumonia and bronchitis. Continued vigilance is crucial given the evolving patterns of this pathogen and other respiratory infections in the post-pandemic era.
Global Incidence and Resistance
The global incidence of invasive group A streptococcus infections and scarlet fever has also risen during the COVID-19 era. A study published in the International Journal of Surgery noted an increase in severe cases, emphasizing the need for ongoing surveillance and effective public health strategies.
Prevention and Treatment Strategies
Preventing Mycoplasma pneumoniae infections requires a multifaceted approach, including vaccination, hygiene practices, and prompt treatment with appropriate antibiotics. Recent publications estimate antibiotic resistance in the United States to be less than 10%, but this figure can vary globally. Effective treatment strategies are essential to manage infections and reduce the risk of complications.
Public Health Measures
Public health containment measures, such as mask-wearing and hand hygiene, have played a critical role in controlling the spread of respiratory infections. As these measures are relaxed, it is essential to continue promoting good hygiene practices and monitoring the incidence of respiratory pathogens.
Conclusion
The reemergence of Mycoplasma pneumoniae infections in children and adolescents post-COVID-19 pandemic underscores the need for continued vigilance and effective public health strategies. Healthcare providers must maintain a high index of suspicion for this pathogen and other respiratory infections, ensuring timely diagnosis and treatment to prevent severe disease outcomes.

Emerging Trends in Mycoplasma pneumoniae infections: A Deep Dive into Recent Research
In the ever-evolving landscape of infectious diseases, Mycoplasma pneumoniae has been making headlines, particularly in the context of the COVID-19 pandemic. This bacterium, known for causing atypical pneumonia, has shown a resurgence in recent years, prompting researchers to delve deeper into its clinical characteristics and treatment challenges.
Beyond the Pandemic: The Persistence of Mycoplasma pneumoniae
A study published in The Lancet Microbe in 2022 highlighted the enduring presence of Mycoplasma pneumoniae beyond the COVID-19 pandemic. The research, conducted by the ESGMAC and the ESGMAC–MyCOVID study group, underscored the importance of continued surveillance and understanding of this pathogen. The study noted that despite the global focus on SARS-CoV-2, Mycoplasma pneumoniae infections remained a meaningful concern, particularly among children.
Respiratory Illnesses on the rise
Data from the European Center for Disease Prevention and Control (ECDC) revealed an increase in respiratory illnesses among children in Beijing, China, during the autumn and winter of 2023. This surge in cases has raised concerns about the impact of Mycoplasma pneumoniae and other respiratory pathogens on pediatric health.
The Impact of Testing Changes
A study published in clinical infectious Diseases suggested that the increased pediatric respiratory syncytial virus (RSV) case counts following the emergence of SARS-CoV-2 could be attributed to changes in testing protocols. This shift in diagnostic practices has also shed light on the prevalence of Mycoplasma pneumoniae infections, which may have been underreported previously.
Severe Manifestations and Treatment Challenges
One of the most concerning aspects of Mycoplasma pneumoniae infections is the potential for severe complications. A case report published in BMC Infectious Diseases described a rare but severe manifestation of the infection, pseudomembranous necrotizing laryngotracheobronchitis. This highlights the need for clinicians to be vigilant for unusual presentations of Mycoplasma pneumoniae infections.
Skin Manifestations and Dermatological Complications
Along with respiratory symptoms, Mycoplasma pneumoniae can also manifest in the skin. A case series published in The Journal of Investigative Medicine detailed bullous skin manifestations associated with Mycoplasma pneumoniae infections. These skin complications can be challenging to diagnose and manage, requiring a multidisciplinary approach.
Clinical Characteristics and Risk Factors
Researchers have been exploring the clinical characteristics of Mycoplasma pneumoniae pneumonia, particularly in children. A study published in Infectious Diseases and Therapy in 2024 examined the risk factors for Mycoplasma pneumoniae necrotizing pneumonia. The findings emphasized the importance of early diagnosis and appropriate treatment to prevent severe complications.
Macrolide Resistance: A Growing Concern
The emergence of macrolide-resistant Mycoplasma pneumoniae strains has become a significant concern.A study published in Emerging Infectious diseases reported on macrolide-resistant infections in children in Ohio, USA. This resistance poses a challenge to treatment options and underscores the need for choice therapeutic strategies.

The Rising Challenge of Macrolide-Resistant Mycoplasma pneumoniae
In the ever-evolving landscape of infectious diseases, one pathogen has been making headlines for its growing resistance to common antibiotics: Mycoplasma pneumoniae.This bacterium,a frequent culprit behind community-acquired pneumonia (CAP) in children,is increasingly displaying resistance to macrolide antibiotics—a class of drugs commonly used to treat infections.
First reported in Japan in 1968, macrolide-resistant Mycoplasma pneumoniae (MRMP) has since spread globally, with varying incidence rates documented across different countries [1[1[1[1]. The Centers for Disease Control and Prevention (CDC) is actively monitoring this trend, tracking resistance through specimens submitted by local and state public health departments [2[2[2[2].
A recent study published in the JAMA network Open provides a comprehensive overview of the global trends in macrolide-resistant Mycoplasma pneumoniae infections. The study, conducted by Yang HJ and Lee E, highlights that while some cases of Mycoplasma pneumoniae infections are self-limiting, others can lead to severe clinical outcomes [3[3[3[3].
The study found that the proportion of macrolide-resistant Mycoplasma pneumoniae infections has been on the rise. This increasing resistance poses a significant challenge to healthcare providers, who are left with fewer effective treatment options.The table below summarizes key findings from the study,offering a snapshot of the global impact of this resistance trend.
| Region | Incidence Rate of MRMP (%) |
|—————–|—————————–|
| Asia | 60-70 |
| Europe | 20-30 |
| North America | 10-20 |
| South America | 10-20 |
| Africa | Limited Data |
The data underscores the need for enhanced surveillance and targeted interventions to manage and mitigate the spread of macrolide-resistant Mycoplasma pneumoniae. As the pathogen continues to adapt and evolve, healthcare systems must remain vigilant and proactive in their approach to treatment and prevention.
