The primary goal of pertussis treatment is to inhibit pathogen proliferation, alleviate symptoms, and prevent complications. Antibiotic therapy is the first choice, especially when administered early in the infection to effectively block transmission. Supportive therapies such as respiratory management and nutritional supplementation are also key components, particularly for infants and immunocompromised patients.
Treatment strategies should be adjusted based on the patient's age, severity of symptoms, and contact history. Early diagnosis and prompt treatment can significantly reduce hospitalization rates, especially in infants under 6 months old, who are at higher risk for pneumonia and respiratory failure, requiring more cautious management.
Antibiotic therapy mainly involves macrolides (such as erythromycin, azithromycin) or second-generation tetracyclines, which work by inhibiting bacterial protein synthesis and cell wall formation. Immunoglobulin therapy is used for high-risk groups, providing immediate antibody protection to neutralize the pathogen.
Supportive therapies include oxygen therapy, tracheal suctioning, and nutritional support. These non-pharmacological measures can effectively improve breathing difficulties and dehydration. In severe cases, intensive care monitoring and mechanical ventilation may be necessary.
Suitable for patients diagnosed with or highly suspected of having pertussis, with antibiotic treatment most effective within two weeks of symptom onset. Contacts who are unvaccinated or immunocompromised are recommended to receive prophylactic antibiotics to block transmission.
Immunoglobulin therapy is indicated for newborns, immunodeficient patients, or those with severe allergy to antibiotics. Treatment should be administered within 72 hours of symptom onset to maximize benefits.
Oral antibiotics such as erythromycin should be taken three times daily for 7-10 days; liquid formulations are suitable for infants and young children. Azithromycin is given as a high-dose short-course therapy over three days to improve compliance.
Intravenous immunoglobulin should be administered in medical facilities, with doses calculated based on body weight. Prophylactic treatment for contacts is recommended using a single dose of azithromycin or erythromycin, with half the usual dose to reduce side effects.
Antibiotics may cause gastrointestinal discomfort such as diarrhea or nausea, with an incidence of approximately 20-30%. Erythromycin may temporarily elevate liver enzymes, requiring regular liver function monitoring.
Severe allergic reactions are rare but can include difficulty breathing or skin rashes. Immunoglobulin therapy may cause fever or injection site swelling; the risk of anaphylactic shock is about 0.01-0.02%.
Contraindications include hypersensitivity to drug components and cautious use of tetracyclines in preterm infants. The use of macrolides during pregnancy should be carefully evaluated for risks. During breastfeeding, short-acting drugs are preferred to reduce infant exposure.
Patients with liver dysfunction should have dosage adjustments; severe liver disease patients are advised to switch to azithromycin. Other respiratory infections should be ruled out before treatment to avoid unnecessary antibiotic use.
Concurrent use with antacids can reduce antibiotic absorption; it is recommended to separate administration times. Combining with anticoagulants may enhance effects, requiring INR monitoring. Immunoglobulin may interfere with live vaccines, which should be administered at least four weeks apart.
When used with theophylline, macrolides may increase blood drug concentrations, requiring blood level monitoring. Concurrent NSAID use may exacerbate gastrointestinal side effects; acetaminophen is preferred for fever reduction.
Studies show that using antibiotics within five days of symptom onset can shorten the disease course by 40-60%. The 2017 WHO guidelines indicate that azithromycin is as effective as erythromycin but has fewer side effects. Using immunoglobulin within 72 hours of exposure can reduce the incidence by 60%.
Supportive therapies can reduce infant hospitalization and mortality to below 1%. Symptoms typically improve 3-5 days earlier after antibiotic treatment, with the infectious period shortened to 24 hours after completing therapy.
For those allergic to antibiotics, amoxicillin-clavulanate can be considered, but resistance issues should be monitored. Supportive therapies include physical expectoration, high-flow oxygen therapy, and nasogastric feeding to maintain nutritional status.
Traditional Chinese medicine adjuncts such as cough-relief teas and acupoint application can alleviate cough spasms but should be used alongside antibiotics. In cases of severe respiratory failure, invasive measures such as tracheal intubation and extracorporeal membrane oxygenation (ECMO) are necessary.
When using antibiotics (such as erythromycin or azithromycin), it is essential to strictly follow the physician's instructions to complete the entire course (usually 10 to 14 days). Avoid discontinuing medication prematurely to prevent resistance. It is recommended to avoid taking the medication with dairy products, as they may affect absorption; if gastrointestinal discomfort occurs, take smaller doses more frequently and consult your doctor for dosage adjustments.
When cough symptoms are severe, what non-pharmacological home remedies can help alleviate cough?Try elevating the upper body during sleep to reduce nighttime coughing, use humidifiers to maintain air humidity (40%-60%), and avoid irritants such as cigarette smoke and dust. Older children and adults can try chest percussion and postural drainage, but avoid direct chest tapping to prevent triggering severe coughing fits.
If vaccinated against pertussis, is antibiotic treatment still necessary if infected?Yes. Although vaccination reduces the risk of infection and severity of symptoms, it does not provide complete immunity. Confirmed cases should still follow medical advice to use antibiotics to shorten infectiousness and reduce transmission risk. Vaccinated individuals may still require treatment due to waning immunity; vaccination alone cannot replace medication.
Does a cough lasting several months after treatment indicate treatment failure or complications?Prolonged cough recovery can last several months, especially after the characteristic 'inspiratory whoop' sound subsides. Persistent dry, irritating cough may continue. If blood-tinged sputum, recurrent fever, or breathing difficulties occur, immediate medical evaluation is necessary to assess for pneumonia or secondary infection, rather than assuming treatment failure.
Should household caregivers contact the patient receive booster vaccines to prevent transmission?It is recommended to verify the tetanus-diphtheria-pertussis (Tdap) vaccination record for cohabitants. If not vaccinated in the past ten years, booster shots should be administered promptly to reduce infection risk. Caregivers with cough symptoms should wear surgical masks and avoid close contact with the patient; prophylactic antibiotics may be considered if necessary.
