We analyzed the performance of p16(INK4a) immunocytochemistry on a series of 810 retrospectively collected atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL) cases with available biopsy follow-up data, including 94 cases of cervical intraepithelial neoplasia (CIN) 2 and 128 cases of CIN 3. Human papillomavirus (HPV) testing was performed from the same residual liquid-based cytologic specimen, and results for both tests were correlated with histologic follow-up data. Sensitivity values for high-grade CIN (HGCIN) confirmed on biopsy within 6 months were 92.6% (ASC-US) and 92.2% (LSIL) for cytotechnologists' reviews of p16 cytology and 90.1% (ASC-US) and 95.7% (LSIL) for HPV testing. Sensitivity rates of initial pathologists' reviews were slightly lower, 76.4% to 80.1%, with levels comparable to cytotechnologists' results after adjudication. The specificity of p16 cytology for HGCIN detection was significantly higher than for HPV testing for cytotechnologists and pathologists: 63.2% to 71.1% (p16 cytology) vs 37.8% for HPV in ASC-US (P < .001) and 37.3% to 53.3% (p16 cytology) vs 18.5% for HPV in LSIL (P < .001). This evaluation of the diagnostic performance of p16 cytology confirms the potential of this stain for the efficient triage of ASC-US and LSIL cytologic results.
Background: Upper respiratory tract infections (URTI) are very common and associated with considerable healthcare costs. We evaluated the clinical benefit of a homeopathic add-on therapy. Patients and Methods: In this randomized controlled multinational clinical trial, patients (age range 1-65 years) with feverish URTI received either on-demand symptomatic standard treatment (ST group: paracetamol, ambroxol, and/or oxymetazoline), or homeopathic medication (IFC group: Influcid®) for 7 days plus the same on-demand standard treatment. URTI symptoms were assessed using the Wisconsin Upper Respiratory Symptom Survey-21. Response at day 4, defined as absence of fever and absence or very mild degree of URTI symptoms, was the primary outcome measure. Results: 523 patients (265 IFC group, 258 ST group) were randomized in 12 Ukrainian and 10 German centers. The responder rate on day 4 was 15.4% in the IFC group and 6.7% in the ST group (ΔIFC-ST = 8.7%, 95% confidence interval 2.9-14.5%). The IFC group used less symptomatic medication, and symptoms were alleviated 1-2 days earlier. 3 and 8 adverse events (AEs) in the IFC and ST group, respectively, were assessed as possibly treatment-related; 2 out of the 3 AEs in the IFC group were possibly related to symptomatic therapy, 1 (vomiting) to IFC treatment. Conclusion: The homeopathic treatment shortened URTI duration, reduced the use of symptomatic medication, and was well tolerated.
We investigated the clinical effectiveness of a homeopathic add-on therapy in a pediatric subpopulation with upper respiratory tract infections (URTI) in a randomized, controlled, multinational clinical trial. Patients received either on-demand symptomatic standard treatment (ST-group) or the same ST plus a homeopathic medication (Influcid; IFC-group) for 7 days. Outcome assessment was based on symptom and fever resolution and the Wisconsin Upper Respiratory Symptom Survey–21 (WURSS-21). A total of 261 pediatric (<12 years) patients (130 IFC-group; 131 ST-group) were recruited in Germany and the Ukraine. The IFC-group used less symptomatic medication, symptoms resolved significantly earlier (P = .0001), had higher proportions of fever-free children from day 3 onwards, and the WURSS-assessed global disease severity was significantly less (P < .0001) during the entire URTI episode. One adverse event (vomiting) was possibly related to IFC. IFC as add-on treatment in pediatric URTI reduced global disease severity, shortened symptom resolution, and was safe in use.
BackgroundThe present study was initiated to investigate the effectiveness, safety and tolerability of complex homeopathic CalSuli-4-02 tablets on prevention of recurrent acute upper respiratory tract infections (URTIs) in children, in comparison to another complex homeopathic product.MethodsThe study was designed as a prospective, multicenter, randomized, open, clinical trial with two parallel treatment groups at four outpatient pediatric clinics in Russia. Children aged ≤ 6 years with susceptibility to acute URTIs (≥ three occasions during the last 6 months) were randomized to receive either CalSuli-4-02 or a comparator homeopathic product (control group) for 3 weeks. Primary outcome was the frequency of acute URTIs after 3 and 6 months post-treatment follow-up. Secondary endpoints were changes in complaints and symptoms (total and individual scores), treatment satisfaction, antibiotic use, safety and tolerability.ResultsThe intention-to-treat analysis involved 200 children (CalSuli-4-02: N = 99, Control: N = 101). In both treatment groups, the median number of acute URTIs was one for 3 months and two, respectively, for the full 6 months post-treatment (Relative Risk: 0.86 (95 %-CI: 0.72–1.03), p = 0.1099). Seasons had no influence on the outcome. At the end of study, CalSuli-4-02 had overall higher odds of getting lower complaints severity total score (Odds ratio: 1.99 (95 %-CI: 1.31–3.02), p = 0.0012) and showing symptom improvement (Odds ratio: 1.93 (95 %-CI: 1.25–3.00), p = 0.0033). Specifically, the complaint “appetite disorder” and the symptom “child’s activities” significantly improved more in the CalSuli-4-02 group (p = 0.0135 and p = 0.0063, respectively). Antibiotic use was decreased in both treatment groups at the study end. Overall assessment for satisfaction with and tolerability of treatment was higher with CalSuli-4-02. A low number of non-serious adverse drug reactions was reported (CalSuli-4-02: N = 4, Control: N = 1).ConclusionsBoth complex homeopathic products led to a comparable reduction of URTIs. In the CalSuli-4-02 group, significantly less URTI-related complaints and symptoms and higher treatment satisfaction and tolerability were detected. The observation that the use of antibiotics was reduced upon treatment with the complex homeopathic medications, without the occurrence of complications, is interesting and warrants further investigations on the potential of CalSuli-4-02 as an antibiotic sparing option.Clinical trial registration numberRoszdravnadzor: Study No 164–563
