The effects of subacute administration of chlorpromazine HCI (CPZ), erythromycine base and erythromycin estolate on the cholestatic response to intravenous taurolithocholate (TLC) and taurochenodeoxycholate (TCDC) in the rat were investigated. All three enhanced the recovery of bile flow after TCDC but not after TLC. Erythromycin base and estolate enhanced bile flow recovery after TCDC and potentiated the increase of plasma 5'-nucleotidase, as did CPZ. Neither erythromycin estolate nor CPZ precipitated a cholestatic response in rat maintained for 9-13 days on a diet supplemented with 0.05% lithocholic acid. It is concluded that the interaction of CPZ and erythromycins with bile salts is not based on the cholestatic properties of the drugs, and hence is not a practical way of distinguishing cholestatic from non-cholestatic drugs.

Erythromycin estolate (EME), a potent macrolide antibiotic, generates free radicals, but their role in the development of liver toxicity is not yet well understood. The present study was carried out to investigate the effect of the antioxidant drug tetrahydrocurcumin (a metabolite of curcumin, the main component of turmeric) against EME-induced lipid peroxidation in rats. The oral administration of combined THC (80 mg/kg body weight) and EME (800 mg/kg body weight) for 15 days significantly decreased lipid peroxidation and enhanced cellular antioxidant defenses when compared with the group treated with EME alone. Supplemental histopathological examination of liver sections revealed that THC had a better antioxidant effect than Silymarin (200 mg/kg body weight), a reference drug. The results of this study indicate that THC affords significant protection against EME-induced lipid peroxidation.

One hundred five Staphylococcus aureus infections occurring in 79 children who were seen in a private office practice were evaluated for response to antibiotic therapy. The value of in vitro disk susceptibility testing in directing antibiotic selection in treatment failures was also examined. Of the total episodes studied, the types of infection studied included vesicular pyoderma (48%), secondary pyoderma (13%), bullous pyoderma (5%), furunculosis (14%), carbunculosis (12%), cellulitis (3%), suppurative otitis media (4%), and paronychia (2%). Comparative treatment efficacy was obtained with perioral erythromycin estolate and erythromycin ethylsuccinate, cefaclor and cephalexin, and clindamycin hydrochloride and dicloxacillin sodium. Penicillin V potassium, ampicillin, and topical bacitracin were generally ineffective. In 23 patients, 27/105 infections were initial treatment failures. Antibiotic disk susceptibility testing predicted these clinical failures and/or the antibiotic that would produce a clinical response in 21 of these 23 patients, suggesting that this office procedure can be of considerable value.

All household contacts of 152 children with culture-positive pertussis who provided consent (n = 362). After withdrawals, there were 135 households with 310 contacts. Exclusions included pregnancy, age <6 months, already receiving an erythromycin-containing antibiotic, and erythromycin allergy. INTERVENTUINS: Erythromycin estolate (40 mg/kg/day in 3 divided doses; maximum dose 1 g) or placebo for 10 days. Nasopharyngeal cultures, pertussis antibodies, and clinical symptoms were assessed before and after treatment.

Five hundred eight-four patients were fully evaluable. The most frequent diagnoses included tonsillopharyngitis (n = 231), otitis media (n = 170) and lower respiratory tract infections (n = 114). Most frequently prescribed antibiotics included amoxicillin (n = 102), potassium penicillin V (n = 81) and clarithromycin (n = 67). Overall compliance (positive urine test) on the last day of therapy was 69.5% (406 of 584 patients). Compliance was not significantly influenced by the region of residence or the underlying bacterial infection. It was significantly associated with the antibiotic used (macrolides, 89.0%; penicillins, 62.2%; cephalosporins, 66.4%; P = 0.0001 for macrolides vs. the others). Best compliance was found with clarithromycin (94.0%) and erythromycin estolate (89.8%). Compliance was also significantly better in patients > or =6 years old (77.7%; P = 0.016); with a treatment duration of < or =7 days (77.6%; P = 0.014); when the drug package contained a dose-taking reminder (79.7%; P = 0.003); and when the pediatrician's behavior toward the patient was assessed by the parents as "very sympathetic" or "sympathetic" (72.6%; P = 0.017). Subjecting all variables to logistic regression analysis, we found 3 variables to be significant predictors of treatment compliance: choice of antibiotic (P = 0.0001); patient age (P = 0.0008); and residence in town or city (P = 0.03).

One hundred and fourteen Corynebacterium diphtheriae, toxigenic, gravis type, pharyngeal carriers were identified during a diphtheria epidemic in Elgin, Texas. All carriers were treated with erythromycin estolate, 1 g/day in divided doses for 6 days. Serial pharyngeal cultures were obtained in order to monitor the bacteriological response. Seventy-two carriers had positive cultures immediately prior to the start of therapy, and only these individuals were considered in the analysis of the effects of erythromycin. Forty-eight hours after institution of therapy, 96% of the carriers had become culture negative; all were negative by the 4th day of therapy, and all remained culture negative while taking the drug. Two days after cessation of therapy, all but one (99%) were culture negative. However, upon reculture 2 weeks later, 15 (21%) had relapsed to the carrier state. There were no significant differences in the serum diphtheria antitoxin levels, immunization status, age, sex, or socioeconomic status of those who relapsed and those who remained culture negative. This study demonstrates that erythromycin is effective in converting carriers to culture-negative status, but when given for only 6 days it is associated with large numbers of relapses. Because previous studies have not included follow-up cultures 2 weeks after therapy, it is suggested that all C. diphtheriae carriers be treated with either erythromycin or penicillin and that all be recultured at a minimum of 2 weeks after completion of therapy to assure eradication of the diphtheria organisms.
The absorptions of 6 erythromycin preparations were compared in a cross-over study in healthy humans. In a single-dose study, 500 mg of each preparation was, after an overnight fast, given to 10 volunteers. The two enterosoluble preparations of erythromycin base studied were absorbed slowly, and the peak serum concentration (1.5-2 mg/l) was achieved only at 4 h. The absorption of the stearates was quick, but especially one of them was poorly absorbed, the serum concentration being always below 1 mg/l. Both of the two estolates gave highest apparent concentrations, and the maximum serum level (2-2.5 mg/l) was achieved at 2 h, but the concentration of active erythromycin remains unknown. In the second part of the study, two erythromycin stearates and one base preparation were given at 6-h interval in a cross-over fashion, each for 4 days. On the 4th day, blood samples were analyzed. The erythromycin base gave higher serum concentrations than did the two stearates, which were equivalent. It seems doubtful that the erythromycin stearate at the dose of 250 mg every 6th hour would give satisfactory serum levels of erythromycin which would be effective against most bacteria during the whole treatment.
Certain macrolide antibiotics, such as troleandomycin (TAO), oleandomycin, and erythromycin estolate (Ilosone), can lower the maintenance dose of glucocorticoids required by severely asthmatic patients. These effects were postulated to be caused by an as yet undefined steroid-sparing effect. In this study, TAO in combination with methylprednisolone, when compared with methylprednisolone alone, was demonstrated to significantly increase liver glycogen deposition in adrenalectomized mice, intact mice, and adrenalectomized rats; protect histamine-sensitized mice following beta adrenergic blockade or adrenalectomy; further decrease the steroid-lowered glucose tolerance of mice and significantly increase the plasma corticosteroid levels in rats. TAO alone did not have these effects. TAO plus betamethasone, and erythromycin estolate plus methylprednisolone also increased liver glycogen deposition. However, TAO did not appear to potentiate the effects of hydrocortisone. Erythromycin stearate and to a lesser degree erythromycin ethylsuccinate when combined with methylprednisolone also decreased histamine lethality in mice. Leucomycin and tetracycline did not enhance the effects of methylprednisolone. TAO, alone or with methylprednisolone, did not alter serum glutamic oxaloacetic transaminase (SGOT) levels in rats. Thus, TAO and some other macrolides did not exert their effects on corticosteroids as antimicrobial agents, adrenocorticotropic hormone (ACTH)--like compounds, or quasisteroids, but as steroid-sparing agents by some undefined mechanism.

The chemistry, bioavailability, and adverse effects of erythromycin base, stearate, estolate, and ethylsuccinate are reviewed. Criteria for the evaluation of erythromycin bioavailability studies include study design, patient population, meal composition and timing, and assay methodology. Based on these criteria, the bioavailability of individual erythromycin products are evaluated in this paper. Compared with other antibiotics, the erythromycins have a good safety record. However, both the estolate and ethylsuccinate forms of erythromycin may cause hepatotoxity. Considering bioavailability and adverse effect data, a specific brand of enteric-coated erythromycin base tablets is recommended for erythromycin-sensitive infections in adults. For pediatric patients, a liquid formulation of erythromycin estolate or erythromycin ethylsuccinate is recommended.

Antibiotics concentrations in middle ear fluid (MEF), saliva and tears were measured in children with persistent middle ear effusions undergoing tympanostomy tube placement. In 31 children given cefaclor, specimens of serum, saliva and MEF were collected at 0.5, 1, 2, 3 or 5 h after a dose. Another group of 37 children were randomized to receive a single dose of penicillin V, amoxicillin, ampicillin, erythromycin estolate, erythromycin ethylsuccinate, trimethoprim-sulfamethoxazole or cefaclor. Concentrations of antibiotics in saliva and tears bore no consistent relationship to those in MEF. Mean concentrations of all drugs in MEF were several-fold greater than the usual minimal inhibitory concentrations (MIC) of pneumococci, but only with trimethoprim and cefaclor were they greater than in usual MIC's for Haemophilus influenzae. Concentrations of antibiotics in MEF in persistent effusions were comparable to those previously reported in acute purulent effusions.

Twelve trials with 1,720 participants met the inclusion criteria. Ten trials investigated treatment regimens and two investigated prophylaxis regimens. The quality of the trials was variable. Results showed that short-term antibiotics (azithromycin for three days, clarithromycin for seven days, or erythromycin estolate for seven days) were equally effective with long-term antibiotic treatment (erythromycin estolate or erythromycin for 14 days) in the microbiological eradication of Bordetella pertussis (B. pertussis) from the nasopharynx. The relative risk (RR) was 1.02 (95% confidence interval (CI) 0.98 to 1.05). Side effects were fewer with short-term treatment (RR 0.66; 95% CI 0.52 to 0.83). There were no differences in clinical improvement or microbiological relapse between short and long-term treatment regimens. Contact prophylaxis (of contacts older than six months of age) with antibiotics did not significantly improve clinical symptoms or the number of cases that developed culture positive B. pertussis.

PL chronica (PLC) was recorded in 37% of the cases, PL et varioliformis acuta (PLEVA) in 57.3%, and clinical features of both disorders were seen simultaneously in the remaining. The median age of onset was 60 months (range: 6-180 months), although the median age of onset of PLEVA (median: 60 months) was significantly younger than that of PLC (median: 72 months) (P = .03). The age distribution showed peaks at 2 to 3 years (24.8%) and 5 to 7 years (32%). A history of infection or drug intake preceded the skin manifestations in 30% and 11.2% of patients with PLC and PLEVA, respectively. The disease began most commonly during winter (35%) or fall (30%). The median duration was 20 months (range: 3-132 months) in patients with PLC and 18 months (range: 4-108 months) in patients with PLEVA. Involvement was diffuse in 74.2% of the patients, peripheral in 20.2%, and central in the remainder. The disease was recurrent in 77% of the patients (n = 80). Of the patients, 59% had pruritus, whereas 32% reported no symptoms; the remainder had fever, arthralgia, or both. Erythromycin estolate or ethylsuccinate was administered to 79.7% of the affected children; 66.6% of these showed at least a partial response.

Because of the lack of a UV chromophore and their much smaller abundances in comparison with the major component, the minor components in erythromycin estolate preparations are difficult to analyze by high performance liquid chromatography ultraviolet (HPLC-UV). Tentative assignment of the major and minor components can be achieved with the combination of full scan and ZoomScan using an ion trap mass spectrometer. Tandem mass spectrometry (MS/MS) provided an effective method to quickly identify most components without chromatographic separation, and all the related compounds, except the isobaric pair ECE and PdMeEA, could be identified in this way. The best result was obtained by using liquid chromatography/tandem mass spectrometry (LC/MS/MS) operated in selected reaction monitoring mode. The major compound, the estolate of erythromycin A (EAE), and seven other minor components, could be separated and identified, with semiquantitative estimates of relative concentrations.

We included one trial, involving 1071 women. Of these, 644 women between 22 weeks and 32 weeks' gestation were randomly assigned to one of three groups of antibiotic treatment (n = 174 erythromycin estolate, n = 224 erythromycin stearate, and n = 246 clindamycin hydrochloride) or a placebo (n = 427). Preterm birth data was not reported in this trial. Incidence of low birthweight less than 2500 grams was only evaluated for erythromycin (combined, n = 398) compared to placebo (n = 427) and there was no statistically significant difference between the two groups (risk ratio (RR) 0.70, 95% confidence interval (CI) 0.46 to 1.07). There were no statistically significant differences in side effects sufficient to stop treatment between either group (RR 1.25, 95% CI 0.85 to 1.85).

The tetracyclines are active in vitro against many urinary tract pathogens such as Chlamydia, Mycoplasma pneumoniae, Brucella, rickettsiae, and Nocardia. Chloramphenicol is used primarily for anaerobic infections, Haemophilus influenzae meningitis, and infections due to Salmonella typhi. Erythromycin is active in vitro against M. pneumoniae, Legionella spp., Streptococcus pneumoniae, and group A beta-hemolytic streptococci; it may also be used as prophylactic therapy for subacute bacterial endocarditis and for recurrence of acute rheumatic fever in patients who are allergic to penicillin. Clindamycin should be used primarily for the treatment of anaerobic infections. The tetracyclines may cause gastrointestinal upset; phototoxic dermatitis; hepatitis, especially in pregnant women; discoloration of the teeth and bone dysplasia in the human fetus and in children; and superinfections, especially oral and anogenital candidiasis. The tetracyclines should be used with caution in patients with renal insufficiency. The most important toxic effect of chloramphenicol is bone marrow suppression, which is dose related or idiosyncratic. The incidence of undesirable side effects associated with the use of erythromycin is low; gastrointestinal irritation is the most common, and cholestatic hepatitis may occur with the use of erythromycin estolate. Pseudomembranous colitis is the most important toxic effect associated with the use of clindamycin.
In an open randomized multicenter study 190 culture-positive pediatric ambulatory pertussis patients were treated for 14 days with either erythromycin estolate (EST) (n = 93; 40 mg/kg/day divided in 2 doses) or erythromycin ethylsuccinate (ETH) (n = 97; 60 mg/kg/day divided in 3 doses). On day 14 Bordetella pertussis was recovered from cultures of 2 patients (2.2%) treated with EST and 1 patient (1.0%) treated with ETH. Despite the fact that 151 patients (79.4%) had reached the early paroxysmal stage at initiation of antimicrobial therapy, clinical improvement was seen in the majority (reduced frequency and severity of coughing: EST, 77.4 and 67.7%; ETH, 74.2 and 63.9%, respectively). Drug-related side effects were noted in 11 patients (11.8%) treated with EST and 16 patients (16.5%) treated with ETH (P greater than 0.05) and consisted mainly of minor gastrointestinal complaints. Erythromycin estolate in a lower dose administered only twice a day was equivalent to erythromycin ethylsuccinate in all aspects and proved to be adequate antimicrobial treatment for pertussis patients.

Suitable antimicrobials given during the catarrhal stage of whooping cough can attenuate the course of the disease. The efficacy of antibiotics administered prophylactically during the incubation period remains controversial but appears to be beneficial. Currently, erythromycin given for two weeks is the antibiotic of choice for pertussis. No treatment failures were observed with erythromycin estolate. Erythromycin ethylsuccinate and stearate must be given at high dosages (50-60 mg/kg/day) in order to achieve sufficient concentrations in the respiratory secretions. With ampicillin and amoxicillin treatment failures have been observed. The role of josamycin and co-trimoxazole in pertussis remains open.

The hepatic clearance and the effects of a new fluorinated macrolide (P-0501A) on the functions of the isolated, perfused rat liver were compared with two known erythromycins--the base and the estolate--after 7 days of treatment (1.36 mmol/kg po daily). The in vitro metabolism of the antibiotics was induced to different extent but only the base and P-0501A were cleared from the perfusate and the liver faster than in untreated animals. In untreated rats the therapeutically active form of P-0501A was excreted in the bile more than the base and the estolate; after pretreatment, biliary excretion of all erythromycins was nearly double. The content of inactive, complexed cytochrome P-450 was increased only by the base and estolate, with various effects on microsomal activities (some induced, e.g. aminopyrine demethylation, other reduced, e.g. pentobarbital clearance). The clearance and biliary excretion of sulphobromophthalein was not affected by treatment with P-0501A or the base, but was significantly reduced by estolate.
The simultaneous determination of erythromycin propionate and erythromycin base in serum and urine by high-performance liquid chromatography using oleandomycin as internal standard is described. The separation was achieved on a reversed-phase C18 column employing acetonitrile-0.05 M phosphate buffer (65:35), adjusted to pH 7.0, as the mobile phase with coulometric detection. Hydrolysis of the ester during blood sample collection was minimised by immediate high-speed centrifugation of collected blood samples, followed by separation and immediate freezing of the serum fraction. A solid-phase extraction procedure, combined with a simple phase-separation step was used prior to chromatographic analysis. The method has the necessary precision, sensitivity and accuracy to allow the simultaneous determination of both components in serum and urine following a single 500-mg oral dose of erythromycin estolate.
Of 456 patients enrolled during 17 consecutive months, 420 were evaluable. Clinical success at Study Days 15 to 19 was 94.6% in the azithromycin group and 96.2% in the comparative treatment group (P = 0.735) and at 4 to 6 weeks posttherapy 90.6 and 87.1%, respectively (P = 0.330). Evidence of infection was identified in 46% of 420 evaluable patients (1.9% bacteria, 29.5% M. pneumoniae and 15% C. pneumoniae). Microbiologic eradication was 81% for C. pneumoniae and 100% for M. pneumoniae in the azithromycin group vs. 100 and 57%, respectively, in the comparator group. Treatment-related adverse events occurred in 11.3% of the azithromycin group and 31% in the comparator group (P < 0.05).

Topical antibiotics were used on patients with acne vulgaris. Corynebacterium acnes organisms from open comedones were quantitated during treatment, and the progress of the disease was evaluated. Clindamycin lotion completely suppressed the growth of C acnes organisms, whereas erythromycin and tetracycline did not depress the C acnes counts. Taken as a group, these antibiotics gave a substantial improvement of the disease on the treated side as compared with paired untreated sides of the face and back.
A total of 477 children were enrolled and randomly assigned to either azithromycin (n = 239) or erythromycin (n = 238). Of these children, 114 (24%) grew B pertussis from nasopharyngeal specimens (azithromycin group: 58 of 239 [24%]; erythromycin group: 56 of 238 [23%]); these children composed the efficacy cohort for the per-protocol and intention-to-treat analyses. Serology and PCR added 52 children to the number considered to have pertussis for a total of 35% (166 of 477) of all children who presented with cough illness. In the safety analysis (antibiotic side effects, compliance) and comparison of cough symptoms after treatment, all randomized children are reported in their assigned treatment group. At end of therapy, bacterial eradication was demonstrated in all 53 patients in the azithromycin group and all 53 patients in the erythromycin group with follow-up cultures available (eradication 100%; 95% confidence interval [CI]: 93.3-100). No bacterial recurrence was demonstrated in children with 1 week posttreatment nasopharyngeal cultures available (51 and 53 participants in the azithromycin and erythromycin arms, respectively [0%, 95% CI: 0-7.0; and 0%, 95% CI: 0-6.7]). No serious adverse events attributable to study drug were observed. Gastrointestinal adverse events were reported less frequently in azithromycin (18.8%; 45 of 239) than in erythromycin estolate (41.2%; 98 of 238) recipients (90% CI on difference: -29.0% to -15.7%) as a result of less nausea (2.9% vs 8.4%; 95% CI: -8.9% to -2.0%), less vomiting (5.0% vs 13.0%; 95% CI: -4.9% to -1.4%), and less diarrhea (7.1% vs 11.8%; 95% CI: -9.0% to -0.3%). Children who were randomized to azithromycin were much more likely to have complied with antimicrobial therapy over the treatment period. In the azithromycin group, 90% of children took 100% of prescribed doses, whereas only 55% of children in the erythromycin group took 100% of prescribed doses.

All splenectomized individuals are at risk of developing pneumococcal sepsis, but most reports fail to mention how many patients are given prophylactic penicillin therapy. Fourteen reported cases of postsplenectomy bacterial sepsis in patients receiving prophylactic penicillin therapy are reviewed. In only five cases, the patients had penicillin-sensitive pneumococcal infection. Hence, the exact frequency of the failure of penicillin prophylaxis cannot be calculated, but it appears to be very rare. Continuous antibiotic prophylaxis used indefinitely and pneumococcal vaccine are both strongly recommended for all children and adults undergoing splenectomy.
