RESUMEN
OBJECTIVE: Previous investigations suggest the use of extract from the root of Pelargonium sidoides (EPs 7630) for the therapy of uncomplicated acute upper airway inflammations, due to its strong antimicrobial and immunomodulatory effect. We aimed to compare clinical efficacy, safety and bactericidal effect of EPs 7630 and amoxicillin monotherapy in treatment of patients with mild to moderate acute bacterial rhinosinusitis (ABRS). METHODS: Fifty ABRS patients were divided into two groups by randomization. Group 1 (n = 25) received EPs 7630 tablets, 3 × 20 mg/day per os for 10 days. Group 2 (n = 25) received amoxicillin tablets 3 × 500 mg/day per os, for 10 days. We assessed total symptom score (TSS), individual symptom scores for each symptom (nasal obstruction, rhinorrhea, postnasal drip, facial pain/pressure, loss of the sense of smell), endoscopic findings, including total endoscopic score (TES) and individual endoscopic signs (mucosal edema, mucopurulent secretion), before and after treatment. Samples of discharge taken from the middle meatus of all patients were cultivated for bacteria before and after therapy. RESULTS: Higher absolute improvement after treatment was found for TSS, nasal obstruction, facial pain/pressure, impaired sense of smell, TES, mucosal edema and mucopurulent secretion in EPs 7630 group compared to amoxicillin group (P < .001 for all parameters). However, there were no differences in absolute improvement of rhinorrhea score and postnasal drip score between groups (P = .248; P = .679, respectively). Fewer types of bacteria grew on culture from middle meatal samples in EPs 7630 group compared to amoxicillin group. There were no reported adverse events from patients from either group. CONCLUSION: Our results demonstrated better clinical and antimicrobial efficacy of EPs 7630 than amoxicillin. EPs 7630 was shown as a potent agent and good alternative to antibiotic treatment of uncomplicated ABRS.

The objective of this study was to determine whether curcumin and a commercial microencapsulated phytogenic supplement containing thymol, cinnamaldehyde and carvacrol in broiler chicken feed would improve health and meat quality (fatty acid profile), as well as to determine the coccidiostatic and bactericidal potential of the additives. The broiler chickens were divided into five groups: NC - negative control feed; PC - positive control; CU - with 50 mg/kg of curcumin, PHY - 100 mg/kg phytogenic; and PHY + CU, a combination of both additives at 50 mg/kg (curcumin) and 100 mg/kg (phytogenic). We observed significantly higher levels of total proteins associated with increased circulating globulins, as well as lower levels of uric acid, cholesterol and triglycerides in the PHY + CU group than in the NC. There were significantly fewer oocysts in birds supplemented with additives in the NC group on day 21; on day 35, the NC, PHY and PHY + CU groups had significantly lower counts than the PC and CU groups; however, at 44 days, the lowest counts were in PC group. The bacterial counts were significantly lower on day 21 in all groups that received additives than those of the control group; however, at 44 days, the bacterial and Escherichia coli counts in these groups were significantly higher than those of the control. Curcumin with or without phytogenic agent improved meat quality, with increased antioxidant levels and reduction of lipid peroxidation. There were significantly lower total saturated fatty acid levels and significantly greater monounsaturated/polyunsaturated fatty acid levels in broilers that consumed additives individually and in combination. The combination of additives significantly increased the crypt/villus ratio, a marker of improved intestinal health and performance. Additives potentiated their individual effects, suggesting they can replace conventional growth promoters without compromising health, intestinal mucosa or meat quality.

A dynamic interplay between the host and pathogen determines the course and outcome of infections. A central venue of this interplay is the struggle for iron, a micronutrient essential to both the mammalian host and virtually all microbes. The induction of the ironregulatory hormone hepcidin is an integral part of the acute phase response. Hepcidin switches off cellular iron export via ferroportin-1 and sequesters the metal mainly within macrophages, which limits the transfer of iron to the serum to restrict its availability for extracellular microbes. When intracellular microbes are present within macrophages though, the opposite regulation is initiated because infected cells respond with increased ferroportin-1 expression and enhanced iron export as a strategy of iron withdrawal from engulfed bacteria. Given these opposing regulations, it is not surprising that disturbances of mammalian iron homeostasis, be they attributable to genetic alterations, hematologic conditions, dietary iron deficiency or unconsidered iron supplementation, may affect the risk and course of infections. Therefore, acute, chronic or latent infections need to be adequately controlled by antimicrobial therapy before iron is administered to correct deficiency. Iron deficiency per se may negatively affect growth and development of children as well as cardiovascular performance and quality of life of patients. Of note, mild iron deficiency in regions with a high endemic burden of infections is associated with a reduced prevalence and a milder course of certain infections which may be traced back to effects of iron on innate and adaptive immune function as well as to restriction of iron for pathogens. Finally, absolute and functional causes of iron deficiency need to be differentiated, because in the latter form, oral iron supplementation is inefficient and intravenous application may adversely affect the course of the underlying disease such as a chronic infection. This chapter summarizes our current knowledge on the regulation of iron metabolism and the interactions between iron and the immune response against microbes. Moreover, some of the unanswered questions on the association of iron administration and infections are addressed.

The modern clinical research on prostatitis started with the work of Stamey and coworkers who developed the basic principles we are still using. They established the segmented culture technique for localizing the infections in the males to the urethra, the bladder, or the prostate and to differentiate the main categories of prostatitis. Such categories with slight modifications are still used according to the NIH classification: acute bacterial prostatitis, chronic bacterial prostatitis, Chronic Pelvic Pain Syndrome (CPPS) and asymptomatic prostatitis. Prostatic inflammation is considered an important factor in influencing both prostatic growth and progression of symptoms of benign prostatic hyperplasia and prostatitis. Chronic inflammation/neuroinflammation is a result of a deregulated acute phase response of the innate immune system affecting surrounding neural tissue at molecular, structural and functional levels. Clinical observations suggest that chronic inflammation correlates with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and benign prostatic hyperplasia (BPH) and an history of clinical chronic prostatitis significantly increases the odds for prostate cancer. The NIHNIDDK classification based on the use of the microbiological 4- glasses localization test or simplified 2-glasses test, is currently accepted worldwide. The UPOINT system identifies groups of clinicians with homogeneous clinical presentation and is used to recognize phenotypes to be submitted to specific treatments. The UPOINTS algorithm implemented the original UPOINT adding to the urinary domains (U), psycho-social (P), organspecific (O), infection (I), neurological (N), muscle tension and tenderness (T) a further domain related to sexuality (S). In fact sexual dysfunction (erectile, ejaculatory, libido loss) has been described in 46-92% of cases with a high impact on the quality of life of patients with CP/CPPS. Prostatic ultrasound represents the most popular imaging test in the work-up of either acute and chronic prostatitis although no specific hypo-hyperechoic pattern has been clearly associated with chronic bacterial prostatitis and CPPS. Use of a digital-processing software to calculate the extension of prostatic calcification area at ultrasound demonstrated a higher percentage of prostatic calcification in patients with chronic bacterial prostatitis. Multiparametric Magnetic Resonance Imaging (mpMRI) is the current state-of-the art imaging modality in the assessment of patients with prostate cancer although a variety of benign conditions, including inflammation, may mimic prostate cancer and act as confounding factors in the discrimination between neoplastic and non-neoplastic lesions. Bacteria can infect prostate gland by: ascending the urethra, reflux of urine into the prostatic ducts, direct inoculation of bacteria through inserted biopsy needles or hematogenous seeding. Enterobacteriaceae are the predominant pathogens in acute and chronic bacterial prostatitis, but an increasing role of Enterococci has been reported. Many strains of these uropathogens exhibit the ability to form biofilm and multidrug- resistance. Sexually Transmitted Infections (STI) agents, in particular Chlamydia trachomatis and Mycoplasma genitalium, have been also considered as causative pathogens of chronic bacterial prostatitis. On the contrary the effective role in genital diseases of other "genital mycoplasmas" is still a much debated issue. Sexually Transmitted Infections agents should be investigated by molecular methods in both patient and sexual partner. "Next generation" investigations, such as cytokine analysis, cytological typing of immune cells could help stratifying the immune response. Epigenetic dysregulation of inflammatory factors should be investigated according to systemic and compartment-specific signals. The search for biomarkers should also include evaluation of hormonal pathways, as measurement of estrogen levels in semen. Antimicrobials are the first line agents for the treatment of bacterial prostatitis. The success of antimicrobial treatment depends on the antibacterial activity and the pharmacokinetic characteristics of the drug which must reach high concentrations in prostate secretion and prostate tissue. Acute bacterial prostatitis can be a serious infection with a potential risk for urosepsis For iInitial treatment of severely ill patients, intravenous administration of high doses of bactericidal antimicrobials, such as broad-spectrum penicillins, third-generation cephalosporins or fluoroquinolones, is recommended in combination with an aminoglycoside. Use of piperacillin-tazobactam and meropenem is justified in presence of multiresistant gramnegative pathogens. The antibiotic treatment of chronic prostatitis is currently based on the use of fluoroquinolones that, given for 2 to 4 weeks, cured about 70% of men with chronic bacterial prostatitis. For the treatment of Chlamydial prostatitis macrolides were shown to be more effective than fluoroquinolones, whereas no differences were observed in microbiological and clinical efficacy between macrolides and tetracyclines for the treatment of infections caused by intracellular pathogens. Aminoglycosides and fosfomycin could be considered as a therapeutic alternative for the treatment of quinolone resistant prostatitis. Use of alpha-blockers in CP/CPPS patients with urinary symptoms and analgesics +/- non steroidal anti-inflammatory drugs (NSAID), in presence of pain demonstrated a reduction of symptoms reduction and an improvement of quality of life, although long term use of NSAID is limited by side effect profile. However, the multimodal therapeutic regimen by contemporary use of alphablockers, antibiotics and anti-inflammatory showed a better control of prostatitis symptoms than single drug treatment. Novel therapeutic substances for the treatment of pain, such as the cannabinoid anandamide would be highly interesting to test. An alternative for the treatment of chronic prostatitis/chronic pelvic pain syndrome is phytotherapy, as primary therapy or in association with other drugs. Quercetin, pollen extract, extract of Serenoa repens and other mixtures of herbal extracts showed a positive effect on symptoms and quality of life without side effects. The association of CP/CPPS with alterations of intestinal function has been described. Diet has its effects on inflammation by regulation of the composition of intestinal flora and direct action on the intestinal cells (sterile inflammation). Intestinal bacteria (microbiota) interacts with food influencing the metabolic, immune and inflammatory response of the organism. The intestinal microbiota has protective function against pathogenic bacteria, metabolic function by synthesis of vitamins, decomposition of bile acids and production of trophic factors (butyrate), and modulation of the intestinal immune system. The alteration of the microbiota is called "dysbiosis" causing invasive intestinal diseases pathologies (leaky gut syndrome and food intolerances, irritable bowel syndrome or chronic inflammatory bowel diseases) and correlating with numerous systemic diseases including acute and chronic prostatitis. Administration of live probiotics bacteria can be used to regulate the balance if intestinal flora. Sessions of hydrocolontherapy can represent an integration to this therapeutic approach. Finally, microbiological examination of sexual partners can offer supplementary information for treatment.

Acute rhinosinusitis is one of the most common conditions that physicians treat in ambulatory care. Most cases of acute rhinosinusitis are caused by viral upper respiratory infections. A meta-analysis based on individual patient data found that common clinical signs and symptoms were not effective for identifying patients with rhinosinusitis who would benefit from antibiotics. C-reactive protein and erythrocyte sedimentation rate are somewhat useful tests for confirming acute bacterial maxillary sinusitis. Four signs and symptoms that significantly increase the likelihood of a bacterial cause when present are double sickening, purulent rhinorrhea, erythrocyte sedimentation rate greater than 10 mm per hour, and purulent secretion in the nasal cavity. Although cutoffs vary depending on the guideline, antibiotic therapy should be considered when rhinosinusitis symptoms fail to improve within seven to 10 days or if they worsen at any time. First-line antibiotics include amoxicillin with or without clavulanate. Current guidelines support watchful waiting within the first seven to 10 days after upper respiratory symptoms first appear. Evidence on the use of analgesics, intranasal corticosteroids, and saline nasal irrigation for the treatment of acute rhinosinusitis is poor. Nonetheless, these therapies may be used to treat symptoms within the first 10 days of upper respiratory infection. Radiography is not recommended in the evaluation of uncomplicated acute rhinosinusitis. For patients who do not respond to treatment, computed tomography of the sinuses without contrast media is helpful to evaluate for possible complications or anatomic abnormalities. Referral to an otolaryngologist is indicated when symptoms persist after maximal medical therapy and if any rare complications are suspected.

The article summarizes 15 years of experience of the use of moxifloxacin (Avelox) in Russia in patients with acute bacterial rhinosinusitis. Emphasize its high bactericidal activity against a broad spectrum of microorganisms- from basic agents to the atypical and anaerobic microflora. The results of these studies suggest the continued effectiveness of the dosage of 400 mg a short course (7 days) over 15 years of practical use of the drug, which in its clinical efficacy is superior to amoxicillin/clavulanate, cefuroxime axetil and levofloxacin. The safety profile of moxifloxacin, studied at the population level is not associated with an increased risk of adverse effects in compliance with the dosing regimen, taking into account the indications and contraindications.

OBJECTIVE: The aim of this study was to discuss the clinical characteristics and results of hand infections in diabetic patients treated with hyperbaric oxygen therapy (HBOT). METHODS: This retrospective study included 10 patients with diabetes mellitus who underwent HBOT due to hand infections between January 2006 and February 2011. RESULTS: Amputation was performed at the level of the right hand index finger proximal interphalangeal joint in 1 patient and at the level of the distal phalanx of the left hand middle finger in 1 due to necrotizing soft tissue infection. Ulcers of 8 patients healed completely without amputation. CONCLUSION: The addition of HBOT to the standard treatment may contribute to the healing of hand ulcers in diabetics by increasing the tissue oxygenation and correcting the process of disturbed wound healing.

This study evaluated the in vitro and in vivo performance of antibiotic-releasing porous polymethylmethacrylate (PMMA)-based space maintainers comprising a gelatin hydrogel porogen and a poly(dl-lactic-co-glycolic acid) (PLGA) particulate carrier for antibiotic delivery. Colistin was released in vitro from either gelatin or PLGA microparticle loaded PMMA constructs, with gelatin-loaded constructs releasing colistin over approximately 7 days and PLGA microparticle-loaded constructs releasing colistin for up to 8 weeks. Three formulations with either burst release or extended release at different doses were tested in a rabbit mandibular defect inoculated with Acinetobacter baumannii (2×10(7) colony forming units ml(-1)). In addition, one material control that released antibiotic but was not inoculated with A. baumannii was tested. A. baumannii was not detectable in any animal after 12 weeks on culture of the defect, saliva, or blood. Defects with high dose extended release implants had greater soft tissue healing compared with defects with burst release implants, with 8 of 10 animals showing healed mucosae compared with 2 of 10 respectively. Extended release of locally delivered colistin via a PLGA microparticle carrier improved soft tissue healing compared with implants with burst release of colistin from a gelatin carrier.

Immobilization is an easy and convenient method to induce both psychological and physical stress resulting in restricted motility and aggression and is believed to be the most severe type of stress in rodent models. Although it has been generally accepted that chronic stress often results in immunosuppression while acute stress has been shown to enhance immune responses, the effects of IS on the host resistance to Escherichia coli (E. coli) infection and associated behavioral changes are still not clear. In a series of experiments aimed at determining the level of hypothalamic COX-2, HSP-90, HSP-70, SOD-1 and plasma level of corticosterone, cytokine, antibody titer and their association with behavioral activities, mice were infected with viable E. coli during acute and chronic IS by taping their paws. In this study we show that acute and chronic IS enhances the resistance of mice to E. coli infection via inhibiting the production of pro-inflammatory cytokines, free radicals, and by improving the exploratory behavior. Altogether, our findings support the notion that cytokines released during immune activation and under the influence of corticosterone can modulate the open field behavior both in terms of locomotor activity as well as exploration. One of the features observed with chronic stressor was a lower ability to resist bacterial infection, although in case of acute stress, a better clearance of bacterial infection was observed in vivo with improvement of exploratory behavior and cognitive functions.

OBJECTIVE: To investigate the role of bacterial infection, antimicrobial sensitivity and antibiotics usage in severe acute exacerbations of COPD requiring mechanical ventilation in the respiratory care unit of the central chest institute of Thailand. MATERIAL AND METHOD: All data were analyzed from medical records of 38 patients admitted in RCU of CCIT during 1 November 2008-31 August 2011 with severe acute exacerbations of COPD requiring mechanical ventilation. The tracheobronchial aspirates specimens were collected for Gram stain, quantitative culture and sensitivities testing. The sera were tested for antibodies to Chlamydophila pneumoniae and Mycoplasma pneumoniae with the immunofluorescence test. RESULTS: Bacterial pathogens were isolated by quantitative culture from 18 of 38 patients (47.3%). Gram-negative bacilli were the predominant organisms. K. pneumoniae was the predominant isolates 7 cases (18.4%) followed by H. influenzae 3 cases and P. aeruginosa 3 cases (7.9% each). A single pathogen was isolated from 12 patients (31.6%), two pathogens were isolated from 5 patients (13.2%) and three pathogens from 1 patient (2.6%). Serological samples were positive for Chlamydophila pneumoniae in 5 (13.2%) cases. 1 of these patients had coinfection with Acinetobacter baumannii. In the RCU, 33 (86.8%) patients were empirically treated with antibiotic. Ceftriaxone was the most commonly used antibiotic. CONCLUSION: 57.8% (22/38 cases) of the patients with severe exacerbations in COPD requiring mechanical ventilation caused by bacterial infection, Gram-negative bacilli were the predominant organism with a resistance to commonly used antibiotics of K. pneumoniae, P. aeruginosa, S. aureus, E. coli, A. baumannii, P. mirabilis, S. dysgalactiae and S. pneumoniae. 13.2% of the patients had serological evidence of Chlamydophila pneumoniae infection.

Chronic obstructive pulmonary disease is a common condition which causes considerable morbidity and mortality. It is a heterogenous disorder in which the majority of patients have chronic bronchitis. Bacterial infections are a major cause of acute exacerbations of both conditions which have a major impact on healthcare resources, quality of life and disease progression. Antibiotics are used to treat exacerbations involving purulent sputum production, together with increased breathlessness and/or sputum volume. Moxifloxacin is a quinolone antibiotic and is one of the treatment options. This article discusses pathophysiology of these diseases, moxifloxacin clinical studies and appropriate use of moxifloxacin.

National guidelines for treatment of ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, and hyponatremia have been approved by the Danish Society of Gastroenterology and Hepatology. Ascites develops in approximately 60% of patients with cirrhosis during a 10 year period and is frequently associated with complications that determine the course of the disease and the prognosis. These evidence-based guidelines are divided in two parts and consider definitions, pathophysiology, diagnostic aspects, treatment, and prophylaxis.

We previously demonstrated the safety and efficacy of fluoroquinolone-macrolide combination therapy in category II chronic bacterial prostatitis (CBP). The aim of this study is to retrospectively compare the microbiological and clinical findings of two treatment schemes for CBP based on the combination of azithromycin (500 mg, thrice-weekly) with a once-daily 500- or 750-mg dose of ciprofloxacin (Cipro-500 or Cipro-750 cohort, respectively). Combined administration of azithromycin (1500 mg week(-1)) with ciprofloxacin at the rate of 750 mg day(-1) for 4 weeks rather than at 500 mg day(-1) for 6 weeks increased the eradication rates from 62.35% to 77.32% and the total bacteriological success from 71.76% to 85.57%. A significant decrease in pain and voiding signs/symptoms and a significant reduction in inflammatory leukocyte counts and serum prostate-specific antigen (PSA) were sustained throughout an 18-month follow-up period in both groups. Ejaculatory pain, haemospermia and premature ejaculation were significantly attenuated on microbiological eradication in both groups, but the latter subsided more promptly in the Cipro-750 cohort. In total, 59 Cipro-750 patients showed mild-to-severe erectile dysfunction (ED) at baseline, while 22 patients had no ED on microbiological eradication and throughout the follow-up period. In conclusion fluoroquinolone-macrolide therapy resulted in pathogen eradication and CBP symptom attenuation, including pain, voiding disturbances and sexual dysfunction. A once-daily 750-mg dose of ciprofloxacin for 4 weeks showed enhanced eradication rates and lower inflammatory white blood cell counts compared to the 500-mg dose for 6 weeks. Our results are open to further prospective validation.

To understand the changing spectrum of neonatal infectious disease, one must first be familiar with the history, the variety of organisms and the progression of change of neonatal infections over the years. As progressively more immature neonates are surviving, the spectrum of infectious disease has changed in response to current medical practice responsible for this success and to selective pressures on the microorganisms. The surviving very low birth weight infants are at a significant risk for contracting infections from this expanding repertoire of pathogens. Microorganisms once thought seemingly benign and nonpathogenic are now commonly accepted as pathogens and are among the most likely organisms to cause infections in this extremely vulnerable patient population. When considering the possible identity of infecting organisms and attempting to tailor specific therapies to decrease unwanted consequences, one must consider the level of maturity and the age of neonate, as well as the intensity of care necessary for a successful outcome. This brief review focuses primarily on the changing spectrum of bacterial and fungal infections and will not substantially address viral infections.

IMPORTANCE OF THE FIELD: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is one of the most common diagnoses arising out of urologic office visits. It is a costly problem and sufferers compare the effect of this syndrome on quality of life as being similar to the effects of diabetes mellitus and myocardial infarction. The syndrome is variable in presentation and symptom management and efficacy will vary between inflicted men. AREAS COVERED IN THIS REVIEW: CP/CPPS is not highly responsive to therapy. As such, it is often a waxing and waning illness with symptoms in multiple domains, including urinary symptoms, pain and ejaculatory dysfunction. The pharmacotherapeutic options and management strategies for CP/CPPS presented in this review are based on the published literature from September 1989 to January 2010. When available, randomized, placebo-controlled studies were reviewed to aid in making definitive recommendations for treatment strategies. WHAT THE READER WILL GAIN: The reader will be familiarized with the commonly used classes of pharmaceutical and non-pharmaceutical therapies. Readers will then use the efficacy data to inform treatment decisions for patients with disparate symptomatology. This will be crystallized in the author's treatment algorithm and summary statement. TAKE HOME MESSAGE: Many practitioners use antimicrobials as a first-line agent, particularly a fluoroquinolone, such as levofloxacin. Trimethoprim/sulfamethoxazole is another medication alternative, with comparable response rates. Many afflicted men will have significant improvement on a 4- to 6-week regimen of a fluoroquinolone antibiotic. Second-line pharmacotherapy includes alpha-blockers, 5-alpha reductase inhibitors and anti-inflammatories for men with urinary symptoms or pain as a predominant symptom domain. Other pharmacotherapy includes steroids, glycosaminoglycans and phytotherapy. Surgical options are generally not recommended for CP/CPPS. Despite the lack of curative therapies, effective symptom management can be achieved with knowledge of the classes of pharmacotherapy. Therapeutic decisions can be based on the symptoms of the patient. Pelvic floor physical therapy is a useful second-line therapy in the author's opinion, but randomized controlled trials and standardization of technique for CP/CPPS are needed before recommendations can be substantiated.

OBJECTIVE: This study compared the clinical efficacy, time to symptom resolution, and tolerability of a 5-day regimen of telithromycin with a 10-day regimen of high-dose amoxicillin-clavulanate in acute bacterial sinusitis (ABS). RESEARCH DESIGN AND METHODS: In this multinational (41 centers in Canada, Germany, Greece, Portugal, and Turkey), open-label, noninferiority study, patients >/=18 years old (n=298) with a clinical (>7 days' symptoms) and radiological (air/fluid level, total opacification, mucosal thickening >/=10 mm) diagnosis of ABS were randomized to receive telithromycin 800 mg once daily for 5 days or amoxicillin-clavulanate 875/125 mg twice daily for 10 days. Clinical efficacy and tolerability were assessed at the test-of-cure visit (days 17-21). Time to symptom resolution was based on patients' daily diary assessment of individual symptoms. RESULTS: The per-protocol clinical success rate (primary endpoint) with telithromycin (88.6% (109/123)) was noninferior to that with amoxicillin-clavulanate (88.8% (111/125)) (95% confidence interval: -8.9 to 8.5). In the modified intention-to-treat (mITT) population, the median time for 50% reduction of total symptom scores was significantly shorter for telithromycin (4 days) vs. amoxicillin-clavulanate (5 days; p=0.044); median times for 75% reduction of total symptom scores were: telithromycin, 7 days; amoxicillin-clavulanate, 8 days (p=0.115). The median time for reduction of total symptom scores to the absent/very mild category (mITT population) was 6 days for telithromycin vs. 8 days for amoxicillin-clavulanate (p=0.04). All treatment-emergent adverse events (TEAEs) were mostly gastrointestinal and occurred in 20.7% (30/145) of telithromycin-treated patients vs. 31.8% (47/148) of amoxicillin-clavulanate-treated patients (p=0.034). One serious AE was reported in the telithromycin group, but it was considered not to be related to treatment. CONCLUSIONS: This open-label, randomized study demonstrated that treatment of ABS with telithromycin resulted in comparable clinical efficacy, shorter times to symptom resolution, and fewer total TEAEs than treatment with amoxicillin-clavulanate.

Sinusitis remains 1 of the most common reasons for antimicrobial prescriptions in the United States, with health care costs approaching $4 billion annually. We utilized the serial sinus aspirate sampling (SSAS) technique to obtain daily specimens to evaluate the time course of drug effect in patients with acute maxillary sinusitis. Eighteen patients with a radiologically confirmed acute maxillary sinusitis were enrolled into a study evaluating the relationship between levofloxacin exposure and the time course of antimicrobial effect using SSAS. SSAS was performed daily during therapy for bacteriologic evaluation. Six steady-state levofloxacin concentrations were obtained. Levofloxacin plasma and sinus aspirate concentrations were modeled using Monte Carlo Parametric Expectation Maximization algorithm implemented in S-ADAPT 1.53. Endpoints evaluated included time to resolution of signs and symptoms and time to sinus sterilization. Among the 18 enrolled patients, 15 were clinically evaluable. From these, 1 Streptococcus pneumoniae, 3 Haemophilus influenzae, 1 Moraxella catarrhalis, 1 Corynebacterium spp., and 1 coagulase-negative Staphylococcus organisms were isolated, with the latter 2 organisms being likely contaminants. For the pathogens, levofloxacin MIC values ranged from 0.03 to 2 mg/L. All pathogens were eradicated by the 4th day of therapy. The median and mean time to sinus sterilization (pathogens only) was 1 and 1.4 days, respectively. The median time to resolution of each sign and symptom ranged from 1.5 to 12-19 days, with the 83% of total signs and symptoms resolved by the end of therapy (day 5). The mean plasma area under the concentration-time curve (AUC) (mg x h/L) was 100.1 (n = 14, %CV = 27). Plasma AUC/MIC ratios ranged from 33.9 to 1696 for isolated pathogens. In this pilot SSAS study, levofloxacin rapidly eradicated isolated pathogens from the maxillary sinus.

Increasing evidence implicates periodontitis, a chronic inflammatory disease of the tooth-supporting structures, as a potential risk factor for increased morbidity or mortality for several systemic conditions including cardiovascular disease (atherosclerosis, heart attack, and stroke), pregnancy complications (spontaneous preterm birth [SPB]), and diabetes mellitus. Cross-sectional, case-control, and cohort studies indicate that periodontitis may confer two- and up to sevenfold increase in the risk for cardiovascular disease and premature birth, respectively. Given the recently acquired knowledge that systemic inflammation may contribute in the pathogenesis of atherosclerosis and may predispose to premature birth, research in the field of periodontics has focused on the potential of this chronic low-grade inflammatory condition to contribute to the generation of a systemic inflammatory phenotype. Consistent with this hypothesis clinical studies demonstrate that periodontitis patients have elevated markers of systemic inflammation, such as C-reactive protein (CRP), interleukin 6 (IL-6), haptoglobin, and fibrinogen. These are higher in periodontal patients with acute myocardial infarction (AMI) than in patients with AMI alone, supporting the notion that periodontal disease is an independent contributor to systemic inflammation. In the case of adverse pregnancy outcomes, studies on fetal cord blood from SBP babies indicate a strong in utero IgM antibody response specific to several oral periodontal pathogens, which induces an inflammatory response at the fetal-placental unit, leading to prematurity. The importance of periodontal infections to systemic health is further strengthened by pilot intervention trials indicating that periodontal therapy may improve surrogate cardiovascular outcomes, such as endothelial function, and may reduce four- to fivefold the incidence of premature birth. Nevertheless, further research is needed to fully discern the underlying mechanisms by which local chronic infections can have an impact on systemic health, and in this endeavor periodontal disease may serve as an ideal disease model.
