Comparative safety of different recommended doses of sodium-glucose cotransporter 2 inhibitors in patients with type 2 diabetes mellitus: a systematic review and network meta-analysis of randomized clinical trials.

Objective: The safety results of different recommended doses of sodium-glucose cotransporter 2 inhibitors (SGLT-2i) for patients with type 2 diabetes mellitus (T2DM) remain uncertain. This study aims to comprehensively estimate and rank the relative safety outcomes with different doses of SGLT-2i for T2DM. Methods: PubMed, Embase, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, Chinese National Knowledge Infrastructure, WanFang database, and SinoMed database were searched from the inception to 31 May 2023. We included double-blind randomized controlled trials (RCTs) comparing SGLT-2i with placebo or another antihyperglycemic as oral monotherapy in the adults with a diagnosis of T2DM. Results: Twenty-five RCTs with 12,990 patients randomly assigned to 10 pharmacological interventions and placebo were included. Regarding genital infections (GI), all SGLT-2i, except for ertugliflozin and ipragliflozin, were associated with a higher risk of GI compared to placebo. Empagliflozin 10mg/d (88.2%, odds ratio [OR] 7.90, 95% credible interval [CrI] 3.39 to 22.08) may be the riskiest, followed by empagliflozin 25mg/d (83.4%, OR 7.22, 95%CrI 3.11 to 20.04)) and canagliflozin 300mg/d (70.8%, OR 5.33, 95%CrI 2.25 to 13.83) based on probability rankings. Additionally, dapagliflozin 10mg/d ranked highest for urinary tract infections (UTI, OR 2.11, 95%CrI 1.20 to 3.79, 87.2%), renal impairment (80.7%), and nasopharyngitis (81.6%) when compared to placebo and other treatments. No increased risk of harm was observed with different doses of SGLT-2i regarding hypoglycemia, acute kidney injury, diabetic ketoacidosis, or fracture. Further subgroup analysis by gender revealed no significantly increased risk of UTI. Dapagliflozin 10mg/d (91.9%) and canagliflozin 300mg/d (88.8%) ranked first in the female and male subgroups, respectively, according to the probability rankings for GI. Conclusion: Current evidence indicated that SGLT-2i did not significantly increase the risk of harm when comparing different doses, except for dapagliflozin 10mg/d, which showed an increased risk of UTI and may be associated with a higher risk of renal impairment and nasopharyngitis. Additionally, compared with placebo and metformin, the risk of GI was notably elevated for empagliflozin 10mg/d, canagliflozin 300mg/d, and dapagliflozin 10mg/d. However, it is important to note that further well-designed RCTs with larger sample sizes are necessary to verify and optimize the current body of evidence.

Real-world safety profile of eculizumab in patients with paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, or generalized myasthenia gravis: an integrated analysis of post-marketing surveillance in Japan.

Eculizumab is a C5 inhibitor approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), and anti-acetylcholine receptor antibody-positive generalized myasthenia gravis (AChR + gMG) in Japan. We report integrated safety data from post-marketing surveillance in these three indications, focusing on commonly occurring adverse events (AEs) and infection-related AEs. Of 1219 patients registered, 1055 (PNH: 780; aHUS: 192; AChR + gMG: 83) had available safety data. Total eculizumab exposure was 3977.361 patient-years. AEs were reported in 74.03% of patients. AEs with an incidence of  ≥ 1.0 per 100 patient-years included hemolysis, headache, nasopharyngitis, renal impairment, anemia, pneumonia, upper respiratory tract inflammation, influenza, condition aggravated, and infection. The incidence of infection-related AEs was 21.30 per 100 patient-years, the most frequent types (≥ 1.0 per 100 patient-years) being nasopharyngitis, pneumonia, influenza, and infection. Meningococcal infections were reported in four patients (0.10 per 100 patient-years). Two patients died from meningococcal sepsis, with a mortality rate of 0.05 per 100 patient-years. This is the largest safety dataset on eculizumab in Japan derived from more than 10 years of clinical experience. No new safety signals were observed and the safety profile of eculizumab was consistent with that in previous clinical trials and international real-world safety analyses.

Long-Term Safety and Tolerability During a Clinical Trial and Open-Label Extension of Low-Sodium Oxybate in Participants with Narcolepsy with Cataplexy.

BACKGROUND: The safety and efficacy of low-sodium oxybate (LXB; Xywav®) were established in a randomized, double-blind, placebo-controlled, phase 3 withdrawal study in adults with narcolepsy with cataplexy; however, the longer-term safety profile has not yet been examined. The aim of the current analysis was to assess the time of onset and duration of common treatment-emergent adverse events (TEAEs) for LXB throughout the open-label optimized treatment and titration period (OLOTTP) and the stable dose period (SDP) portions of the main study, and the subsequent 24-week open-label extension (OLE). METHODS: In a double-blind, placebo-controlled, randomized withdrawal trial of LXB, TEAEs were evaluated during the 12-week OLOTTP, the 2-week SDP, and the subsequent 24-week OLE. Eligible participants were aged 18-70 years with a diagnosis of narcolepsy with cataplexy. At study entry, participants were taking sodium oxybate (SXB) alone, SXB with other anticataplectics, other anticataplectics alone, or were anticataplectic-treatment naive; other anticataplectics were tapered and discontinued during the OLOTTP. All participants initiated LXB during week 1 of the OLOTTP, and their dose was individually titrated based on safety and efficacy. Following the main study period, participants entered the OLE after rescreening (re-entry) after discontinuing LXB treatment or directly after completing the main study (rollover). TEAEs were assessed in the safety population as of database lock. TEAE duration was defined as time from TEAE start date to end date (or end of SDP or OLE, if end date was unrecorded). RESULTS: The safety population included 201 participants (SXB alone, n = 52; SXB with other anticataplectics, n = 23; other anticataplectics alone, n = 36; anticataplectic-treatment naive, n = 90). During the OLOTTP/SDP, headache was the most common LXB-emergent TEAE overall (71 events; n = 42 (21%); median (range) duration = 1 (1-147) day), followed by nausea (31 events; n = 26 (13%); median (range) duration = 9 (1-54) days) and dizziness (26 events; n = 21 (10%); median (range) duration = 7 (1-117) days). Among the 74 participants in the OLE, the most commonly reported TEAEs were headache (14 events; n = 7, 9%; peak incidence month 3 (n = 5/72); median (range) duration = 1 (1‒25) day), dizziness (8 events; n = 5, 7%; peak incidence month 1 (n = 3/74); median (range) duration = 26 (1‒181) days), and nasopharyngitis (6 events; n = 6, 8%; peak incidence month 6 (n = 2/69); median (range) duration = 9 (1‒24) days). Overall, study discontinuations attributed to TEAEs were 21/65 (32%) during the OLOTTP and SDP and 3/7 (43%) during the OLE. CONCLUSIONS: In this long-term analysis, the safety and tolerability profile of LXB was generally consistent with the known safety profile of SXB. During the OLOTTP and SDP, most TEAEs occurred early and were generally of short duration. TEAE prevalence decreased throughout the duration of the OLE; the most common TEAEs reported during the OLE were headache, dizziness, and nasopharyngitis. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03030599 (25 January 2017).

Low-sodium oxybate (LXB) is a medicine for narcolepsy. LXB treats daytime sleepiness and cataplexy (sudden muscle weakness). LXB is like sodium oxybate (SXB) but has 92% less sodium. This study looked at side effects in people taking LXB for many months. Three study periods were looked at in this report. In period 1, people could change their LXB dose for 12 weeks. This was to find their best dose. In period 2, people took that same best dose for 2 weeks. In period 3, some people kept taking LXB for 24 weeks. This was to study the longer-term effects. Everyone knew that they were taking LXB. During periods 1 and 2, the most common side effect was headache. Nausea and dizziness were also common. During period 3, headache was also the most common side effect. Dizziness and nasopharyngitis were also common. Nasopharyngitis is a cold in the nose and throat. In periods 1 and 2, most side effects happened early on. They also ended quickly. Fewer side effects happened in period 3. Among people leaving the study early, 32% left because of side effects during periods 1 and 2. During period 3, 43% left because of side effects. Overall, long-term side effects in people taking LXB were similar to those seen with SXB.

Safety and tolerability of spesolimab in patients with ulcerative colitis.

BACKGROUND: Interleukin (IL)-36 signaling has been shown to be increased in ulcerative colitis (UC). Spesolimab, a novel humanized monoclonal antibody, targets the IL-36 pathway. RESEARCH DESIGN AND METHODS: We report safety, immunogenicity, and efficacy data of intravenous (IV) spesolimab in UC. Study 1: phase II, randomized, placebo-controlled trial (300 mg single dose; 450 mg every 4 weeks [q4w]; or 1,200 mg q4w, three doses). Study 2: phase IIa, randomized, placebo-controlled trial (1,200 mg q4w). Study 3: phase IIa, open-label, single-arm trial (1,200 mg q4w). Studies lasted 12 weeks, with a 12-, 24-, and 16-week safety follow-up, respectively. RESULTS: Adver+se event (AE) rates were similar for spesolimab and placebo in Studies 1 (N = 98; 64.9%; 65.2%) and 2 (N = 22; 86.7%; 71.4%); all patients in Study 3 (N = 8) experienced AEs. The most frequent investigator-assessed drug-related (spesolimab; placebo) AEs were skin rash (5.4%; 0%) and nasopharyngitis (4.1%; 0%) in Study 1; acne (13.3%; 0%) in Study 2; one patient reported skin rash, nasopharyngitis, headache, and acne in Study 3. Efficacy endpoints were not met. CONCLUSIONS: Spesolimab was generally well tolerated, with no unexpected safety concerns. The safety data are consistent with studies in other inflammatory diseases.

Risk of infections of biological and targeted drugs in patients with spondyloarthritis: meta-analysis of randomized clinical trials.

BACKGROUND: Concerns exist regarding the risk of infections in patients with spondyloarthritis (SpA) treated with biologics. We assessed the risk of infections of biological and targeted drugs in patients with SpA by performing a meta-analysis based on randomized controlled trials (RCTs). METHODS: A systematic literature search was conducted in PubMed, Embase, Web of Science, the Cochrane Library, and China Biology Medicine Disc for RCTs evaluating the risk of infections of biological therapy in patients with SpA from inception through August 9, 2021. We calculated a pooled Peto odds ratio (OR) for infections in biologics-treated patients vs. placebo patients. The risk of bias on the included RCTs was assessed by using the Cochrane Risk of Bias Tool. RESULTS: In total, 62 studies were included in this meta-analysis. Overall, the risk of infection (Peto OR: 1.16, 95% confidence interval [CI]: 1.07-1.26, P < 0.001), serious infection (Peto OR: 1.65, 95% CI: 1.26-2.17, P < 0.001), upper respiratory tract infection (URTI) (Peto OR: 1.17, 95% CI: 1.04-1.32, P = 0.008), nasopharyngitis (Peto OR: 1.25, 95% CI: 1.10-1.42, P < 0.001), and Candida infection (Peto OR: 2.64, 95% CI: 1.48-4.71, P  = 0.001) were increased in SpA patients treated with biologics compared with placebo. Sensitivity analysis based on biologics classes was conducted, and results demonstrated that compared with placebo, there was a higher risk of infection for tumor necrosis factor (TNF)-a inhibitors (Peto OR: 1.38, 95% CI: 1.13-1.68, P  = 0.001) and interleukin (IL)-17 inhibitors (Peto OR: 1.55, 95% CI: 1.08-2.22, P  = 0.018) in axial SpA, and for Janus kinase inhibitors in peripheral SpA (Peto OR: 1.39, 95% CI: 1.14-1.69, P  = 0.001); higher risk of serious infection for IL-17 inhibitors in peripheral SpA (Peto OR: 3.46, 95% CI: 1.26-9.55, P = 0.016) and axial SpA (Peto OR: 2.01, 95% CI: 1.38-2.91, P < 0.001); higher risk of URTI for TNF-a inhibitors in axial SpA (Peto OR: 1.37, 95% CI: 1.05-1.78, P = 0.019), and for apremilast in peripheral SpA (Peto OR: 1.60, 95% CI: 1.08-2.36, P = 0.018); higher risk of nasopharyngitis for TNF-a inhibitors in axial SpA (Peto OR: 1.41, 95% CI: 1.05-1.90, P = 0.022) and peripheral SpA (Peto OR: 1.49, 95% CI: 1.09-2.05, P = 0.013), and for IL-17 inhibitors in axial SpA (Peto OR: 1.35, 95% CI: 1.01-1.82, P = 0.044); higher risk of herpes zoster for Janus kinase inhibitors in peripheral SpA (Peto OR: 2.18, 95% CI: 1.03-4.62, P = 0.043); higher risk of Candida infection for IL-17 inhibitors in peripheral SpA (Peto OR: 2.52, 95% CI: 1.31-4.84, P = 0.006). CONCLUSIONS: This meta-analysis shows that biological therapy in patients with SpA may increase the risk of infections, including serious infections, URTI, nasopharyngitis, and Candida infection, which should be paid attention to in our clinical practice.

Infectious events in patients treated with immune checkpoint inhibitors, chimeric antigen receptor T cells, and bispecific T-cell engagers: a review of registration studies.

BACKGROUND: Immunological treatments (immune checkpoint inhibitors [ICIs], chimeric antigen receptor T [CAR-T] cells, bispecific T-cell engagers [BiTEs]) have deeply changed the treatment of several cancers. However, the impact of these treatments on the risk of developing infections has not been completely ascertained yet. METHODS: We reviewed all the registration studies of currently approved ICIs, CAR-T cells, and BiTEs to collect all the reported infections. For each drug, we have generated a report with the infections occurring in at least 10% of the patients enrolled. RESULTS: The most frequently reported infections involving patients treated with ICIs involved the respiratory tract, including nasopharyngitis, upper respiratory tract infections, and pneumonia and the urinary tract. Those treated with CAR-T cells frequently reported the incidence of unspecified infections and infestations, bacterial infections, and viral infections. In patients treated with BiTEs, nasopharyngitis, pneumonia, and device-related infections were the most frequently reported conditions. CONCLUSIONS: A wide range of infections are reported in registration studies and clinical trials of ICIs, CAR-T cells, and BiTEs.

A first case report of nasopharyngeal Mycobacterium abscessus subspecies massiliense infection.

BACKGROUND: Mycobacterium abscessus subspecies massiliense is a non-tuberculous mycobacteriosis and was subdivided from Mycobacterium abscessus in 2006. This article is the first report on nasopharyngitis caused by Mycobacterium abscessus subspecies massiliense. CASE PRESENTATION: A 45-year-old woman had an 18-month history of recurrent nasopharyngitis and presented with pain in the throat. Mycobacterial tissue culture and polymerase chain reaction testing revealed the presence of Mycobacterium abscessus subspecies massiliense in the nasopharyngeal tissue. This patient underwent surgery, followed by multiple rounds of chemotherapy with oral and intravenous antibiotic agents for 16 weeks. She has had no recurrence during the 56 weeks since treatment. CONCLUSION: It is difficult to detect the presence of Mycobacterium abscessus subspecies massiliense in a culture from the swabbing sample. The tissue culture from a biopsy specimen is mandatory for the identification of the species. Currently, no definite treatment policy is available and only empirical treatment is applied. This case is an important for the diagnosis and treatment of this bacterial infection on nasopharynx.

Nasopharyngeal linguatulosis or halzoun syndrome: clinical diagnosis and treatment.

OBJECTIVE: Halzoun syndrome, also known as nasopharyngeal linguatulosis, is a rare entity that is mostly prevalent in Eastern Mediterranean countries. The consumption of raw ovine liver and lymph nodes infested with Linguatula serrata nymphs remains a major cause of the nasopharyngeal symptoms and discomfort associated with the disease. Halzoun syndrome is a clinical diagnosis based on history and presentation. METHODS: Treatment of this disease is still debated; however, our experience reveals that alcohol gargle can be a good option. Proper counselling on the hazards of eating raw liver in endemic areas is needed. RESULTS: Moreover, physicians should be aware of the sequence of events in the disease in order not to delay or miss the diagnosis. CONCLUSIONS: This communication presents a rare Lebanese case of Halzoun syndrome that offers medical implications in the clinical diagnosis and treatment of the nasopharyngeal symptoms of this syndrome, with a review of the literature.

Nasopharyngeal linguatulosis or halzoun syndrome: clinical diagnosis and treatment

SUMMARY Halzoun syndrome, also known as nasopharyngeal linguatulosis, is a rare entity that is mostly prevalent in Eastern Mediterranean countries. The consumption of raw ovine liver and lymph nodes infested with Linguatula serrata nymphs remains a major cause of the nasopharyngeal symptoms and discomfort associated with the disease. Halzoun syndrome is a clinical diagnosis based on history and presentation. Treatment of this disease is still debated; however, our experience reveals that alcohol gargle can be a good option. Proper counselling on the hazards of eating raw liver in endemic areas is needed. Moreover, physicians should be aware of the sequence of events in the disease in order not to delay or miss the diagnosis. This communication presents a rare Lebanese case of Halzoun syndrome that offers medical implications in the clinical diagnosis and treatment of the nasopharyngeal symptoms of this syndrome, with a review of the literature.

RESUMO Esta comunicação apresenta um caso libanês raro de síndrome de Halzoun que oferece implicações médicas no diagnóstico clínico e no tratamento dos sintomas nasofaríngeos desta síndrome, com uma revisão da literatura. A síndrome de Halzoun, também conhecida como linguatulose nasofaríngea, é uma entidade rara predominante nos países do Mediterrâneo Oriental. O consumo de linfonodos ovinos e linfáticos ovinos infestados com ninfas Linguatula serrata continua a ser uma das principais causas dos sintomas nasofaríngeos e do desconforto associado à doença. A síndrome de Halzoun é um diagnóstico clínico baseado na história e na apresentação. O tratamento dessa doença ainda é debatido; no entanto, nossos resultados revelam que o gargarismo de álcool pode ser uma boa opção. É necessário um aconselhamento adequado sobre os perigos de comer fígado cru em áreas endêmicas. Além disso, os médicos devem estar cientes da sequência de eventos na doença, a fim de não atrasar ou perder o diagnóstico.

Long-term Safety and Efficacy of Reslizumab in Patients with Eosinophilic Asthma.

BACKGROUND: In placebo-controlled trials, reslizumab, an anti-IL-5 monoclonal antibody, significantly reduced asthma exacerbations and improved lung function and asthma control in patients with eosinophilic asthma. OBJECTIVE: This open-label extension study evaluated safety and efficacy of reslizumab for up to 24 months. METHODS: After participation in 1 of 3 placebo-controlled, phase III trials in moderate-to-severe eosinophilic asthma, patients received reslizumab 3.0 mg/kg intravenously every 4 weeks for up to 24 months. Adverse events (AEs), lung function, and patient-reported asthma control were evaluated. RESULTS: In the open-label extension, 1,051 patients received ≥1 reslizumab dose (480 reslizumab-naïve, 571 reslizumab-experienced); median (range) exposure was 319 (36-840) and 343 (36-863) days in reslizumab-naïve and reslizumab-experienced patients, respectively. Continuous exposure, including during the placebo-controlled studies, was ≥12 months for 740 patients and ≥24 months for 249 patients. The most common AEs were worsening of asthma and nasopharyngitis. Serious AEs affected 78 of 1,051 (7%) patients; 18 of 1,051 (2%) discontinued treatment because of AEs; and there were 3 deaths (all non-treatment-related). Fifteen adult patients (15 of 1,023; 1%) had malignancies of diverse tissue types. Reslizumab-experienced patients maintained improved lung function and asthma control; reslizumab-naïve patients had improvements in these measures throughout open-label treatment. Blood eosinophil counts appeared to be returning to baseline after reslizumab discontinuation. CONCLUSIONS: In patients with moderate-to-severe eosinophilic asthma, intravenous reslizumab 3.0 mg/kg displays favorable long-term safety and sustained long-term efficacy. Initial improvements in lung function and asthma control were maintained for up to 2 years. These findings substantially add to our understanding of the long-term safety and efficacy of anti-IL-5 strategies.

Short-term increase in prevalence of nasopharyngeal carriage of macrolide-resistant Staphylococcus aureus following mass drug administration with azithromycin for trachoma control.

BACKGROUND: Mass drug administration (MDA) with azithromycin is a corner-stone of trachoma control however it may drive the emergence of antimicrobial resistance. In a cluster-randomized trial (Clinical trial gov NCT00792922), we compared the reduction in the prevalence of active trachoma in communities that received three annual rounds of MDA to that in communities that received a single treatment round. We used the framework of this trial to carry out an opportunistic study to investigate if the increased rounds of treatment resulted in increased prevalence of nasopharyngeal carriage of macrolide-resistant Staphylococcus aureus. Three cross-sectional surveys were conducted in two villages receiving three annual rounds of MDA (3 × treatment arm). Surveys were conducted immediately before the third round of MDA (CSS-1) and at one (CSS-2) and six (CSS-3) months after MDA. The final survey also included six villages that had received only one round of MDA 30 months previously (1 × treatment arm). RESULTS: In the 3 × treatment arm, a short-term increase in prevalence of S. aureus carriage was seen following MDA from 24.6% at CSS-1 to 38.6% at CSS-2 (p < 0.001). Prevalence fell to 8.8% at CSS-3 (p < 0.001). A transient increase was also seen in prevalence of carriage of azithromycin resistant (AzmR) strains from 8.9% at CSS-1 to 34.1% (p < 0.001) in CSS-2 and down to 7.3% (p = 0.417) in CSS-3. A similar trend was observed for prevalence of carriage of macrolide-inducible-clindamycin resistant (iMLSB) strains. In CSS-3, prevalence of carriage of resistant strains was higher in the 3 × treatment arm than in the 1 × treatment (AzmR 7.3% vs. 1.6%, p = 0.010; iMLSB 5.8% vs. 0.8%, p < 0.001). Macrolide resistance was attributed to the presence of msr and erm genes. CONCLUSIONS: Three annual rounds of MDA with azithromycin were associated with a short-term increase in both the prevalence of nasopharyngeal carriage of S. aureus and prevalence of carriage of AzmR and iMLSB S. aureus. TRIAL REGISTRATION: This study was ancillary to the Partnership for the Rapid Elimination of Trachoma, ClinicalTrials.gov NCT00792922 , registration date November 17, 2008.

Endoscopic and clinical benefits of hyaluronic acid in children with chronic adenoiditis and middle ear disease.

Hyaluronic acid (HA) is involved in modulating inflammatory airway processes and mucociliary clearance. Some studies have tested the effectiveness of the topical administration of HA in patients with upper airway diseases with positive preliminary results. A prospective, single-blind, 1:1 randomised controlled study was performed to assess the efficacy and safety of the daily topical administration of 9 mg of sodium hyaluronate in 3 mL of a 0.9 % sodium saline solution on the basis of endoscopic and clinical parameters in children with chronic adenoiditis associated with recurrent acute otitis media and otitis media with effusion; age- and gender-matched children receiving normal 0.9 % sodium chloride saline solution were used as controls. Analysis was based on 103 (mean age 63.3 ± 18.2 months; 52 males, 50.5 %) children: 54 in the study group and 49 in the control group. A statistically significant reduction in the mean number of all acute otitis media episodes (AOME) (mean reduction 0.8 ± 0.4 per month; p value 0.05) and AOME without tympanic membrane perforation (mean reduction 0.6 ± 0.3 per month; p value 0.04) after recruitment was documented only in the study group. HA significantly improved all the endoscopic outcomes (p values ranging between 0.05 and <0.01) but one. Nasal washing with saline solution was effective on only three of them (p values ranging between 0.03 and <0.01). No untoward effects were documented. Our results confirm the safety and document the positive effect of topically administered HA solution on children with chronic adenoiditis associated with middle ear disease.

[The possibilities for the rational pharmacotherapy of adenoiditis in the children]. / Vozmozhnosti ratsional'noi farmakoterapii adenoidita u detei.

The available literature data give evidence that viral infection is the main cause underlying the development of inflammatory nasopharyngeal pathology in the children. According to ICD-10, nether acute nor chronic adenoiditis should be considered as a self-consistent nosological entity. Acute adenoiditis is usually regarded as a form of acute nasopharyngitis (J02) or acute respiratory viral infection (J06.9) whereas chronic adenoiditis is commonly referred to as representing other chronic diseases of the tonsils and adenoids (J 35.8). The reactive changes in the nasopharyngeal tonsils begin to be manifested on days 3-5 after the onset of acute respiratory viral infection; thereafter, they persist and gradually disappear within the next 2-3 weeks. In the majority of the cases, acute adenoiditis is actually a physiological reaction of the nasopharyngeal tonsils as the organs of regional mucosal immunity to antigenic stimulation. There is no universally accepted opinion as regards the duration of the inflammatory process which would allow these pathological changes to be considered as turned into chronic ones. This condition is actually not a serious pathology provided it is not associated with the concomitant complications and produces no clinically significant effect on the child's quality of life. Under practical conditions, such children are most frequently treated with the use of irrigation therapy. Taking into account that otorhinolaryngologists all over the world do not consider chronic adenoiditis as an independent nosological entity but distinguish only hypertrophy of adenoid vegetations or chronic rhinosinusitis (in the presence of inflammatory changes in the nasopharynx), it appears correct to speak about chronic adenoiditis provided the clinical manifestations of the disease persist for more than 12 weeks. Based on the predominant etiological component, the viral, bacterial, and allergic forms of nasopharyngeal adenoiditis can be distinguished even though it is rather difficult to actually determine which etiological factor prevails in each concrete case. The aforedescribed situation poses a large number of questions pertaining to the choice of either systemic or topical antibacterial therapy.

Association of laryngeal and nasopharyngeal tuberculosis: a case report.

INTRODUCTION: To the best of our knowledge, the association of nasopharyngeal and laryngeal tuberculosis has never been described before in the literature. We report here a first observation. CASE PRESENTATION: We report the case of a 38-year-old Arab man who presented with an isolated hoarseness. Radiological and endoscopic examinations showed a thickening of the left lateral wall of his nasopharynx and the left vocal cord. Pathology revealed the diagnosis of tuberculosis of both localizations. He received a 6-month antituberculous chemotherapy with a satisfying uneventful evolution. CONCLUSIONS: Tuberculosis should be considered in the differential diagnosis of soft tissue masses of the head and neck, particularly when the imaging findings and clinical presentation are atypical. The diagnosis of tuberculosis is mainly based on histopathological and/or bacteriological examination.

[The possibilities for the treatment of exudative otitis media in the children presenting with chronic adenoiditis].

The objective of the present study was to improve the effectiveness of medicamental therapy of exudative otitis media in the children with recurrent and chronic adenoiditis. It was shown that the use of fluifort (carbocysteine lysine salt) for the treatment of exudative otitis media in the children presenting with chronic adenoiditis is a more effective approach in comparison with the expectant management. It is concluded that the application of carbocysteine lysine salt in combination with the mometasone furoate nasal spray ensures the rapid elimination of the symptoms of adenoiditis and significantly accelerates the resolution of exudative otitis media compared with the monotherapeutic treatment.

[The experience with the application of selective polarized chromotherapy in the clinical practice].

A series of investigations have demonstrated the anti-inflammatory, bactericidal, analgesic, and vegetocorrective effects of extraocular selective polarized chromotherapy using blue and red light and the possibility to optimize autonomous regulation with the help of this technique. The results of the study confirmed the high clinical effectiveness and safety of the method being considered for the treatment of acute respiratory diseases, chronic tonsillitis, cervical dorsopathies, and vegetative dysfunction.

The utility of nasopharyngeal culture in the management of chronic adenoiditis.

OBJECTIVES: To examine the utility of nasopharyngeal culture in the management of children with chronic adenoiditis to determine if it results in a change in antibiotic therapy. METHODS: Retrospective chart review of pediatric patients managed for chronic adenoiditis, being defined as cough, postnasal drip, and congestion for over three months with endoscopic evidence of nasopharyngeal purulence with normal anterior rhinoscopy and middle meati. Standard treatment was defined as amoxicillin clavulanate or amoxicillin clavulanate ES-600 in non-penicillin allergic patients, and cefuroxime or clarithromycin for penicillin allergic patients. Nasopharyngeal culture results and antibiotic prescriptions were reviewed to look for a change from the standard. RESULTS: Of 207 patients diagnosed with chronic adenoiditis, 198 had nasopharyngeal cultures (119 male, 79 female, mean age 3.7 years). The most common organisms isolated were Streptococcus pneumoniae sensitive to penicillin in 40 cultures (20.2%), S. pneumoniae intermediate or resistant to penicillin in 26 (13.1%), Moraxella catarrhalis in 27 (13.6%), Haemophilus influenzae in 57 (28.8%), and Staphylococcus aureus intermediate or resistant to penicillin in 26 (13.1%). 13.3% of S. aureus isolated was methicillin resistant. 103 (52.0%) children required different antibiotics from the standard, and 26 (13.1%) had no antibiotics prescribed based on a negative culture. Of the 87 children suspected to have upper airway reflux, 25 (28.7%) had negative cultures. Of the 135 patients with follow-up, 50 (37.0%) reported resolution and 50 (37.0%) reported improvement of their symptoms. CONCLUSION: Nasopharyngeal culture has significant utility in the choice of antibiotics for children with chronic adenoiditis.

Intranasal drug-induced fungal rhinopharyngitis.

BACKGROUND: Intranasal drug abuse has long been recognized as an etiology of sinonasal pathology. However, the intranasal use of prescription and nonprescription drugs has surpassed the use of illicit drugs, and the pattern of presentation and required therapeutic intervention appears to be different. We report on our experience with these patients, along with a successful treatment algorithm for this disease process. METHODS: Retrospective chart review of 9 consecutive patients who presented with rhinopharyngitis and a history of intranasal opioid and/or acetaminophen abuse, from 2007 to 2010, at a tertiary referral center. RESULTS: Nine patients were found to have abused intranasal hydrocodone/acetaminophen, oxycodone/aceta-minophen, or acetaminophen and were diagnosed with rhinopharyngitis. Sinonasal pain and odynophagia were the most common chief complaints and 8 of 9 patients reported previous antibiotic failures. On endoscopy, all patients exhibited a thick, white, exudative process involving the nasal septum and lateral nasal mucosa. Five of 9 exhibited large septal perforations. Seven of 9 exhibited white, exudative pharyngitis. Seven of 9 patients had identifiable fungal organisms on culture, including 5 with species of Candida and 3 with Aspergillus. Two patients grew Staphylococcus aureus. Five patients were compliant with follow up. All 5 showed significant improvement in symptoms and examination, following treatment with oral and topical antifungal therapy and nasal irrigations. CONCLUSION: Intranasal opioid and acetaminophen abuse is often associated with the development of fungal rhinopharyngitis. Recognizing that this process is primarily fungal in origin is paramount to successful treatment, as most patients respond well to antifungal therapy when compliant with treatment.

[Immunomodulators for topical application to prevent and manage chronic adenoiditis in children].

The authors report the results of a study on the efficacy of topical application of the immunomodulator IRS 19 in children presenting with chronic adenoiditis and grade I-III hypertrophy of adenoid vegetation. The use of this preparation is shown to faster and more efficaciously normalize the volume of the lymphoid tissue than irrigation of the nasopharynx with saline solutions. Moreover, the treatment of chronic adenoiditis with IRS 19 promoted normalization of biocenosis of the nasopharyngeal secretion and significantly decreased the abundance of pathogenic microflora. Specifically, the overall frequency of exacerbations and the frequency of exacerbations of adenoiditis decreased three- and two-fold respectively while the duration of the disease shortened. It is recommended that the topical immunomodulator IRS 19 should be included in the programs of planned seasonal treatment of children suffering chronic adenoiditis (to be applied at least 2-3 times annually).
