To compare clinical response to initial empiric treatment with oxacillin plus ceftriaxone and amoxicillin plus clavulanic acid in hospitalized children diagnosed with very severe community-acquired pneumonia (CAP).
                A prospective randomized clinical study was conducted among children 2 months to 5 years old with a diagnosis of very severe CAP in the pediatric ward of São Paulo State University Hospital in Botucatu, São Paulo, Brazil, from April 2007 to May 2008. Patients were randomly divided into two groups by type of treatment: an oxacillin/ceftriaxone group (OCG, n = 48) and an amoxicillin/clavulanic acid group (ACG, n = 56). Analyzed outcomes were: time to clinical improvement (fever and tachypnea), time on oxygen therapy, length of stay in hospital, need to widen antimicrobial spectrum, and complications (including pleural effusion).
                The two groups did not differ statistically for age, sex, symptom duration before admission, or previous antibiotic treatment. Time to improve tachypnea was less among ACG patients than OCG patients (4.8 ± 2.2 versus 5.8 ± 2.4 days respectively; P = 0.028), as was length of hospital stay (11.0 ± 6.2 versus 14.4 ± 4.5 days respectively; P = 0.002). There were no statistically significant differences between the two groups for fever improvement time, time on oxygen therapy, need to widen antimicrobial spectrum, or frequency of pleural effusion.
                Both treatment plans are effective in treating very severe CAP in 2-month-to 5-year-old hospitalized children. The only analyzed outcome that favored amoxicillin/clavulanic acid treatment was time required to improve tachypnea.
                ClinicalTrials.gov ID: NCT01166932. Co-trimoxazole is widely used in treatment of paediatric pneumonia in developing countries, but drug resistance may decrease its effectiveness. We studied the effectiveness of co-trimoxazole compared with that of amoxycillin in pneumonia therapy, and assessed the clinical impact of co-trimoxazole resistance.
                We recruited 595 children, aged 2-59 months, with non-severe or severe pneumonia (WHO criteria) diagnosed in the outpatient wards of two urban Pakistan hospitals. Patients were randomly assigned on a 2:1 basis co-trimoxazole (n=398) or amoxycillin (n=197) in standard WHO doses and dosing schedules, and were monitored in study wards. The primary outcome was inpatient therapy failure (clinical criteria) or clinical evidence of pneumonia at outpatient follow-up examination.
                There were 92 (23%) therapy failures in the co-trimoxazole group and 30 (15%) in the amoxycillin group (p=0.03)-26 (13%) versus 12 (12%) among children with non-severe pneumonia (p=0.856) and 66 (33%) versus 18 (18%) among those with severe pneumonia (p=0.009). For patients with severe pneumonia, age under 1 year (p=0.056) and positive chest radiographs (p=0.005) also predicted therapy failure. There was no significant association between antimicrobial minimum inhibitory concentration and outcome among bacteraemic children treated with co-trimoxazole.
                Co-trimoxazole provided effective therapy in non-severe pneumonia. For severe, life-threatening pneumonia, however, co-trimoxazole is less likely than amoxycillin to be effective. To ascertain whether therapeutic equivalence exists for the treatment of paediatric community acquired pneumonia by the oral and intravenous (IV) routes.
                A multicentre pragmatic randomised controlled non-blinded equivalence trial was undertaken in eight paediatric centres in England (district general and tertiary hospitals). Equivalence was defined as no more than a 20% difference between treatments of the proportion meeting the primary outcome measure at any time. 246 children who required admission to hospital and had fever, respiratory symptoms or signs and radiologically confirmed pneumonia were included in the study. Exclusion criteria were wheeze, oxygen saturations <85% in air, shock requiring >20 ml/kg fluid resuscitation, immunodeficiency, pleural effusion at presentation requiring drainage, chronic lung condition (excluding asthma), penicillin allergy and age <6 months. The patients were randomised to receive oral amoxicillin for 7 days (n = 126) or IV benzyl penicillin (n = 120). Children in the IV group were changed to oral amoxicillin after a median of six IV doses and received 7 days of antibiotics in total. The predefined primary outcome measure was time for the temperature to be <38 degrees C for 24 continuous hours and oxygen requirement to cease. Secondary outcomes were time in hospital, complications, duration of oxygen requirement and time to resolution of illness.
                Oral amoxicillin and IV benzyl penicillin were shown to be equivalent. Median time for temperature to settle was 1.3 days in both groups (p<0.001 for equivalence). Three children in the oral group were changed to IV antibiotics and seven children in the IV group were changed to different IV antibiotics. Median time to complete resolution of symptoms was 9 days in both groups.
                Oral amoxicillin is effective for most children admitted to hospital with pneumonia (all but those with the most severe disease who were excluded from this study). Prior to this study, the British Thoracic Society guidelines on childhood pneumonia could not draw on evidence to address this issue. This will spare children and their families the trauma and pain of cannulation, and children will spend less time in hospital. Children in developing countries who present with malnutrition often have infections, particularly pneumonia, at the time of presentation. We evaluated the initial antibiotic management of 144 Gambian children who presented for the first time with malnutrition and who had clinical or radiologic evidence of pneumonia. They were enrolled in a double blind trial of trimethoprim-sulfamethoxazole vs. chloramphenicol. Most children in the study underwent detailed investigations of bacterial and viral etiology as part of another study. The study drug was administered for a week along with oral metronidazole, vitamins and standardized nutritional therapy. Treatment failure was defined as the need for change to parenteral antibiotics during treatment, failure to respond to a week of treatment with the study drug or relapse during the following 2 weeks. There were no differences between the treatment groups in the clinical indicators of severity, etiology or radiologic findings. Thirty-three children were excluded from the analysis because of tuberculosis, inappropriate enrollment or inadequate follow-up. Of the 111 children remaining, 32 (16 in each arm of the study) failed treatment. Clinical failure was not related to in vitro antimicrobial resistance in the 20 cases in which invasive bacterial isolates were obtained. Those who failed treatment were more likely to have had lower chest wall indrawing and positive bacterial cultures than those who were successfully treated. In an area with infrequent antimicrobial resistance of common respiratory pathogens, oral chloramphenicol and trimethoprim-sulfamethoxazole were equally effective in the initial management of malnourished children with community-acquired pneumonia. The diagnosis and the treatment of community-acquired severe pneumonia is still a serious child health problem in developing countries. The aim of this study is to evaluate the effectiveness of two different antibiotic regimens in the empirical treatment of severe childhood pneumonia.
                We enrolled 97 infants (aged 2-24 months) with severe community-acquired pneumonia in a randomized-controlled trial of 10 days of treatment with penicillin G+chloramphenicol (n:46) or ceftriaxone (n:51). We evaluated the effectiveness of treatments with symptoms and some laboratory tests during and at the end of the study.
                The cure rates were similar in both groups and the antibiotic regimens in all patients were found effective (P< 0.001). The number of nurse rounds was much more in penicillin plus chloramphenicol group than ceftriaxone group.
                Both penicillin G plus chloramphenicol and ceftriaxone are effective in the empirical treatment of severe community pneumonia of young children. In spite of more nurse visits for antibiotic treatment, penicillin G+ chloramphenicol combination may be a cheaper alternative to ceftriaxone in the treatment of childhood pneumonia. To compare the efficacy of sequential injectable crystalline penicillin (C.pen) and gentamicin combination followed by oral amoxicillin with sequential IV and oral amoxicillin-clavulanate (amox-clav) in treatment of severe or very severe hypoxemic pneumonia.
                Children aged 2-59 months with WHO-defined severe or very severe pneumonia with hypoxemia (SpO2 < 90%) were included in the study. Patients with fever > 10 days, bacterial meningitis, prior antibiotic therapy > 24 hours, stridor, heart disease and allergy to any of the study drugs were excluded. They were randomly allocated to two groups--Group A and Group B. Group A received C. pen and gentamicin intravenously (IV), followed by oral amoxicillin and group B got amox-clav IV, followed by oral amox-clav. Minimum duration of IV therapy was 3 days and total 7 days. Respiratory rate, oxygen saturation and chest wall indrawing were monitored 6 hourly.
                71 patients were included. There were two (5.2%) blood cultures positive in group A and three (9%) in group B. Organisms isolated were S. pneumoniae (n=3) and H. influenzae-b (n=2). There was only one treatment failure in each of the groups. One was due to penicillin resistant H. influenzae -b and the other was due to worsening of pneumonia. The mean time taken for normalization of tachypnea, hypoxia, chest wall indrawing and inability to feed was similar (P-N.S). Mean duration of IV therapy in group A was 76+/-25 hrs and group B was 75+/-24 hrs (p>0.1).
                In children of 2-59 months, sequential injectable C. pen and gentamicin combination, followed by oral amoxicillin or sequential IV and oral amox-clav were equally effective for the treatment of severe or very severe hypoxemic community acquired pneumonia. To evaluate whether five days' treatment with injectable ampicillin plus gentamicin compared with chloramphenicol reduces treatment failure in children aged 2-59 months with community acquired very severe pneumonia in low resource settings.

                Chloramphenicol versus a combination of ampicillin plus gentamicin.
                Primary outcome measure was treatment failure at five days. Secondary outcomes were treatment failure defined similarly among all participants evaluated at 48 hours and at 10 and 21 days.
                More children failed treatment with chloramphenicol at day 5 (16% v 11%; relative risk 1.43, 95% confidence interval 1.03 to 1.97) and also by days 10 and 21. Overall, 112 bacterial isolates were obtained from blood and lung aspirates in 110 children (11.5%), with the most common organisms being Staphylococcus aureus (n=47) and Streptococcus pneumoniae (n=22). In subgroup analysis, bacteraemia with any organism increased the risk of treatment failure at 21 days in the chloramphenicol group (2.09, 1.41 to 3.10) but not in the ampicillin plus gentamicin group (1.12, 0.59 to 2.13). Similarly, isolation of S pneumoniae increased the risk of treatment failure at day 21 (4.06, 2.73 to 6.03) and death (5.80, 2.62 to 12.85) in the chloramphenicol group but not in the ampicillin plus gentamicin group. No difference was found in treatment failure for children with S aureus bacteraemia in the two groups, but the power to detect a difference in this subgroup analysis was low. Independent predictors of treatment failure by multivariate analysis were hypoxaemia (oxygen saturation <90%), receiving chloramphenicol, being female, and poor immunisation status.
                Injectable ampicillin plus gentamicin is superior to injectable chloramphenicol for the treatment of community acquired very severe pneumonia in children aged 2-59 months in low resource settings.
                Current Controlled Trials ISRCTN39543942. Pneumonia is the most frequent cause of child mortality in less-developed countries. We aimed to establish whether the combination of benzylpenicillin and gentamicin or chloramphenicol would be better as first-line treatment in children with severe pneumonia in Papua New Guinea.
                We did an open randomised trial in which we enrolled children aged 1 month to 5 years of age who fulfilled the WHO criteria for very severe pneumonia and who presented to hospitals in two provinces. Children were randomly assigned to receive chloramphenicol (25 mg/kg 6 hourly) or benzylpenicillin (50 mg/kg 6 hourly) plus gentamicin (7.5 mg/kg daily) by intramuscular injection. The primary outcome measure was a good or an adverse outcome.
                1116 children were enrolled; 559 children were treated with chloramphenicol and 557 with benzylpenicillin and gentamicin. At presentation the median haemoglobin oxygen saturation was 71% (IQR 57-77) for those allocated chloramphenicol and 69% (55-77) for those allocated penicillin and gentamicin. 147 (26%) children treated with chloramphenicol and 123 (22%) treated with penicillin and gentamicin had adverse outcomes (p=0.11). 36 children treated with chloramphenicol and 29 treated with penicillin and gentamicin died. More children treated with chloramphenicol than penicillin and gentamicin represented with severe pneumonia within 1 month of hospital discharge (p=0.03).
                For children with severe pneumonia in less-developed countries the probability of a good outcome is similar if treated with chloramphenicol or with the combination of benzylpenicillin and gentamicin. This study, which aimed to assess the results of three different regimens in the treatment of pneumonia, was carried out at the Pediatric Outpatient Department of Capa Children's Hospital in Istanbul on 151 patients aged between 4 months and 14 years. The first group (n = 46) received co-trimoxazole orally for 10 days and the second group (n = 63) procaine penicillin G in intramuscularly for 10 days. Benzathin penicillin G combined with procaine penicillin G was given to the third group (n = 42) as a single dose intramuscularly. While the best results were obtained with penicillin procaine G, no statistically significant difference was found between this regimen and co-trimoxazole therapy (chi 2 = 0.305023 P = 0.5). We suggest that co-trimoxazole is easy to administer and cost effective in the ambulatory treatment of pneumonia in children.
For treatment of patients with CAP in ambulatory settings, amoxycillin is an alternative to co-trimoxazole. With limited data on other antibiotics, co-amoxyclavulanic acid and cefpodoxime may be alternative second-line drugs. Children with severe pneumonia without hypoxaemia can be treated with oral amoxycillin in an ambulatory setting. For children hospitalised with severe and very severe CAP, penicillin/ampicillin plus gentamycin is superior to chloramphenicol. The other alternative drugs for such patients are co-amoxyclavulanic acid and cefuroxime. Until more studies are available, these can be used as second-line therapies.
There is a need for more studies with radiographically confirmed pneumonia in larger patient populations and similar methodologies to compare newer antibiotics. Recommendations in this review are applicable to countries with high case fatalities due to pneumonia in children without underlying morbidities and where point of care tests for identification of aetiological agents for pneumonia are not available.
