RESUMO
Background: Among several treatment options for BRAF-mutant metastatic melanoma, a combination of BRAF inhibitor, MEK inhibitor, and anti-PDL1 antibody seems to be a new emergent approach recently registered in the Russian Federation. It is still not clear which patient population benefits more from this simultaneous use of three drugs instead of its sequencing. Aim: This study aimed to evaluate patients' characteristics treated in real practice in 14 Russian regions by triple combination and to analyze their outcomes depending on biomarkers (PD-L1 expression). Methods: This was a part (cohort A1) of a prospective non-interventional study of clinical outcomes and biomarkers in patients with skin melanoma. Patients were included in cohort A1 if combination treatment with vemurafenib (vem) + cobimetinib (cobi) + atezolizumab (atezo) was initiated no earlier than 12 weeks (84 days) prior to written informed consent to participate in this study. The index event was the initiation of therapy with all three drugs vem + cobi + atezo (i.e., triple combination). The primary efficacy endpoint of the study was the 24-month overall survival (OS), defined as the time from the index date to the date of death from any cause. If the patient did not experience an event, the OS will be censored at the date of the last contact. Objective response rate (ORR), duration of response (DoR), and progression-free survival (PFS) in the Intention to treat (ITT) population, in biomarker positive population, and in population with brain metastases were also evaluated. Quality of life questionnaires were pre-planned by protocol if it was a part of routine practice. Adverse events were also collected. Results: Between March 2021 and May 2023, 59 patients were enrolled in 19 centers from 14 regions of Russia. Thirty-one of 59 (52.4%) patients had central nervous system metastases, and 18 of 31 (58.4%) were symptomatic. Forty of 59 patients (68%) received the triple combination as the first-line treatment. The median follow-up period was 16.83 [95% confidence interval (CI) 13.8-19.8] months. The mean duration of therapy with this regimen was 9.95 months (95% CI 7.48-13.8). ORR was 55.1%; progression as the best outcome was seen in 16.3%. The median DoR was 12.95 months (95% CI 11.0-14.8 months), with a median of 20.3 months (95% CI 9.1-31.5 months) when triple therapy was administered in the first-line treatment. In patients with brain metastases (N = 31), ORR was 45.1%; the median DoR was 12.95 (95% CI 11.0-14.8 months). The median PFS in the entire population was 13.6 months (95% CI 8.6-18.6); the 24-month PFS was 22%. The estimated median OS in the entire population was 15.8 months (95% CI NA); 24-month OS was 45% (95% CI 0.32-0.64). In multivariate Cox regression model, biomarkers of interest [lactate dehydrogenase, Programmed cell death ligand-1 (PD-L1)] did not have statistically significant impact on PFS, OS, or DoR probably due to high data missing rate. No unexpected adverse events were reported. Grades 3-4 AEs were seen in 23 of 59 patients (38%) with most common were skin and liver toxicity. Conclusion: Triple combination of atezolizumab, vemurafenib, and cobimetinib had proven its efficacy and tolerability in real settings. No impact of potential predictive biomarkers was seen (NCT05402059).
RESUMO
Purpose: COPD affects more than 300 million people worldwide, requiring inhalation treatment. Novel triple formulations of ICS, LABAs and LAMAs are becoming the mainstay of treatment, however there is still a lack of clinical evidence for personalized therapy. Patients and Methods: RATIONALE was a non-interventional, prospective, 52 week study, assessing the effectiveness of beclometasone/formoterol/glycopyrronium-bromide (BDP/FF/G), in symptomatic COPD patients, with moderate airflow obstruction. The study included 4 visits, where data on demographic parameters, exacerbations, symptoms, quality of life (based on the EQ-5D-3L questionnaire) and lung function were collected. Data on adherence to treatment, based on prescriptions filled was collected from the database of the National Health Insurance Fund, with the patients' consent. The primary objective was the change of adherence to treatment during the study, compared to baseline. Results: Altogether 613 patients had been enrolled. Their average age was 64.56 years and 50.5% were female. The average CAT score was 20.86, and most patients had suffered minimum one exacerbation (82.2%). Average FEV1 was 59.6%. Most patients had some limitation in one or more dimensions of EQ-5D-3L, with an average visual analogue scale score (VAS) of 60.31. After 12 months of treatment, adherence improved significantly - proportion of patients in the highest adherence group increased from 29.8% to 69.7% (p<0.001). The average CAT score improved by 7.02 points (95% CI 5.82-8.21, p<0.001). There was a significant improvement in all dimensions of EQ-5D-3L, with an average increase of 17.91 (95% CI 16.51-19.31, p< 0.001) points in the VAS score. Exacerbation frequency also decreased significantly. Conclusion: Although limitations of observational studies are present, we observed that early introduction of fixed triple combination results in a marked improvement in adherence to treatment, symptom scores, exacerbation frequency and quality of life. The optimal choice of treatment is crucial for reaching the highest possible adherence.

BACKGROUND: Although post-inflammatory hyperpigmentation (PIH) is a common adverse event following laser procedures, studies evaluating its risk remain limited. OBJECTIVE: To analyze PIH risk after 532 nm Q-switched Nd:YAG laser (QSNYL) treatment for solar lentigines and examine the efficacy of triple combination cream (TCC) for its prevention. METHODS: In this single center, investigator-blinded, randomized controlled study, participants with solar lentigo either received TCC or emollient from 2 weeks post-QSNYL treatment. The occurrence of PIH was determined by three independent and blinded dermatologists. In vivo skin measurements and sun exposure questionnaires were examined to evaluate the risk of PIH. RESULTS: A total of 28 patients with 67 solar lentigines were included in the analysis. In the control group, PIH occurred in 55.3% of the lesions. Risk factors for the occurrence of PIH were the increased erythema at weeks 2 (OR, 1.32; p = 0.035) and outdoor activity during 1-5 pm (OR, 8.10; p = 0.038). Treatment with TCC from 2 weeks post-QSNYL treatment significantly decreased the incidence of PIH (31.0% vs. 55.3%, p = 0.048). CONCLUSION: Post-laser erythema and outdoor activity at the daytime are prognostic factors for the occurrence of PIH. Administering TCC could be considered for the prevention of PIH in high-risk patients.

Diagnosis and treatment of pulmonary hypertension (PH) in patients with lung diseases (PH-LD) remain unestablished and pose significant challenges. In this report, we present a case of a 77-year-old patient with an indeterminate for usual interstitial pneumonia pattern along with chronic obstructive pulmonary disease, who developed groups 1 and 3 PH. Following diagnosis, upfront triple oral combination therapy (UTOCT) with macitentan, sildenafil, and selexipag was initiated. Stability in disease progression was achieved over 4 years with the addition of pirfenidone to address interstitial lung disease progression. To the best of our knowledge, this represents the first reported case of PH-LD, where disease control was maintained with the addition of pirfenidone to UTOCT. This case suggests that some patients with PH-LD, presenting with groups 1 and 3 PH, may benefit from combined UTOCT and antifibrotic agents, potentially improving symptoms and extending their prognosis.
RESUMO
INTRODUCTION: According to Global Initiative for Asthma (GINA) guidelines, long-acting muscarinic antagonists (LAMAs) should be considered as add-on therapy in patients with asthma that remains uncontrolled, despite treatment with medium-dose (MD) or high-dose (HD) inhaled corticosteroids (ICS)/long-acting ß2-agonist (LABA) combinations. In patients ≥ 18 years, LAMA may be added in triple combination with an ICS and a LABA. To date, the precise efficacy of triple ICS/LABA/LAMA combination remains uncertain concerning the impact on exacerbation risk in patients with uncontrolled asthma. Therefore, an umbrella review was performed to systematically summarize available data on the effect of triple ICS/LABA/LAMA combination on the risk of asthma exacerbation. METHODS: An umbrella review has been performed according to the PRIOR statement. RESULTS: The overall results obtained from 5 systematic reviews and meta-analyses suggest that triple ICS/LABA/LAMA combination reduces the risk of asthma exacerbation. HD-ICS showed a greater effect particularly in reducing severe asthma exacerbation, especially in patients with evidence of type 2 inflammation biomarkers. CONCLUSIONS: The findings of this umbrella review suggest an optimization of ICS dose in triple ICS/LABA/LAMA combination, based on the severity of exacerbation and type 2 biomarkers expression.

This study aimed to evaluate the effectiveness and safety of an oral sequential triple combination therapy with selexipag after dual combination therapy with endothelin receptor antagonist (ERA) and phosphodiesterase-5 inhibitor (PDE5I)/riociguat in pulmonary arterial hypertension (PAH) patients. A total of 192 PAH patients from 10 centers had received oral sequential selexipag therapy after being on dual-combination therapy with ERA and PDE5i/riociguat for a minimum of 3 months. Clinical data were collected at baseline and after 6 months of treatment. The study analyzed the event-free survival at 6 months and all-cause death over 2 years. At baseline, the distribution of patients among the risk groups was as follows: 22 in the low-risk group, 35 in the intermediate-low-risk group, 91 in the intermediate-high-risk group, and 44 in the high-risk group. After 6 months of treatment, the oral sequential triple combination therapy resulted in reduced NT-proBNP levels (media from 1604 to 678 pg/mL), a decline in the percentage of WHO-FC III/IV (from 79.2% to 60.4%), an increased in the 6MWD (from 325 ± 147 to 378 ± 143 m) and a rise in the percentage of patients with three low-risk criteria (from 5.7% to 13.5%). Among the low-risk group, there was an improvement in the right heart remodeling, marked by a decrease in right atrium area and eccentricity index. The intermediate-low-risk group exhibited significant enhancements in WHO-FC and tricuspid annular plane systolic excursion. For those in the intermediate-high and high-risk groups, there were marked improvements in activity tolerance, as reflected by WHO-FC and 6MWD. The event-free survival rate at 6 months stood at 88%. Over the long-term follow-up, the survival rates at 1 and 2 years were 86.5% and 86.0%, respectively. In conclusion, the oral sequential triple combination therapy enhanced both exercise capacity and cardiac remodeling across PAH patients of different risk stratifications.
RESUMO
BACKGROUND: While the GRIPHON study and others have confirmed the efficacy and safety of selexipag with single, dual, and initial triple combination therapy for patients with pulmonary arterial hypertension (PAH), multicenters studies concerning diverse triple oral combination therapies based on selexipag are limited. HYPOTHESIS: This study was conducted to evaluate the effects of various sequential triple oral combination therapies on PAH outcomes. METHODS: A retrospective study was carried out involving 192 patients from 10 centers, who were receiving sequential triple oral combination therapy consisting of an endothelin receptor antagonist (ERA), a phosphodiesterase 5 inhibitor (PDE5i)/riociguat and selexipag. Clinical parameters, event-free survival, and all-cause survival were assessed and analyzed at baseline and posttreatment. RESULTS: Among the 192 patients, 37 were treated with ERA + riociguat + selexipag, and 155 patients received ERA + PDE5i + selexipag. Both sequential triple oral combination therapies improved the World Health Organization functional class and raised the count of low-risk parameters. As a result of the larger patients' population in the ERA + PDE5i + selexipag group, these individuals exhibited significant increases in 6-minute walking distance (6MWD), pulmonary arterial systolic pressure, pulmonary arterial pressure, right ventricle, and eccentricity index, and significant decreases in N-terminal probrain natriuretic peptide after 6 months of treatment. Nevertheless, both sequential triple oral combination therapy groups demonstrated similar shifts in these clinical parameters between baseline and 6 months. Baseline 6MWD and mean pulmonary arterial pressure were independent predictors of survival in patients undergoing ERA + PDE5i + selexipag therapy. Importantly, no significant differences were found in 6-month event-free survival and all-cause survival between two groups. CONCLUSIONS: Different oral sequential triple combination therapies based on selexipag could comparably improve outcomes in patients with PAH.

BACKGROUND: Sequential triple combination therapy is recommended for pulmonary arterial hypertension (PAH) patients who are not at therapeutic goal on dual therapy, but long-term data on efficacy and safety is scarce. OBJECTIVE: To assess the long-term impact of sequential triple combination therapy in patients with PAH who are not at goal on dual combination therapy. STUDY DESIGN AND METHODS: We performed a retrospective observational study in a racially/ethnically diverse cohort of consecutive PAH patients on a stable dual therapy regimen who remained in intermediate- or high-risk category and were subsequently initiated on sequential triple combination therapy. We studied interval change in functional, echocardiographic, and hemodynamic parameters, REVEAL 2.0 risk category and ERS/ESC 2022 simplified four-strata risk category. Multivariate logistic regression analysis was performed to identify independent predictors of successful risk reduction (achievement or maintenance of REVEAL 2.0 low-risk category). Kaplan-Meier survival curves were created to assess the effect of risk reduction on survival. RESULTS: Out of 414 PAH patients seen in our program, 55 patients received add-on sequential triple combination regimen and had follow-up hemodynamic data. The mean age was 57 years, with 85% women. The most common etiology of PAH was idiopathic/heritable (41.8%). Most patients were WHO functional class III (76.4%), and 34.5% of patients were in high-risk category (REVEAL 2.0). On a median follow-up of 68 weeks, there was a significant improvement in WHO Functional Class (p < 0.001), six-minute walk distance (35 m) with 61.8% of patients achieving low-risk status by REVEAL 2.0, and a 28% of patients' improvement in pulmonary vascular resistance. Female gender was identified as a strong predictor of successful risk reduction, whereas Hispanic ethnicity estimated right atrial pressure on echocardiogram and pericardial effusion predicted lower probability of risk reduction. Patients who achieved or maintained low-risk status had significantly improved survival. CONCLUSION: Add-on sequential triple combination therapy significantly increased functional, echocardiographic, and hemodynamic parameters with improvement in risk category and survival.

The authors evaluated the efficacy, safety, and characteristics of patients who respond well to standard dose triple combination therapy including chlorthalidone 25 mg with telmisartan 80 mg plus amlodipine 5 mg in hypertensive patients. This is a multicenter, double-blind, active-controlled, phase 3, randomized trial. Patients are randomized to triple combination (telmisartan 40 mg/amlodipine 5 mg/chlorthalidone 12.5 mg, TEL/AML/CHTD group) or dual combination (telmisartan 40 mg/amlodipine 5 mg, TEL/AML group) treatment and then dose up titration to TEL 80/AML5/CHTD25mg and TEL80/AML5, respectively. The primary endpoint is the change of mean sitting systolic blood pressure (MSSBP) at week 8. A Target BP achievement rate, a response rate, and the safety endpoints are also evaluated. Total 374 patients (mean age = 60.9 ± 10.7 years, male = 78.3%) were randomized to the study. The baseline MSSBPs/diastolic BPs were 149.9 ± 12.2/88.5 ± 10.4 mm Hg. After 8 weeks treatment, the change of MSSBPs at week 8 are -19.1 ± 14.9 mm Hg (TEL/AML/CHTD) and -11.4 ± 14.7 mm Hg (TEL/AML) (p < .0001). The achievement rates of target BP (53.8% vs. 37.8%, p = .0017) and responder rate (54.8% vs. 35.6%, p = .0001) at week 8 were significantly higher in TEL/AML/CHTD. There are no serious adverse event and no one discontinued medication due to adverse event. Among the TEL 80/AML5/CHTD25mg treatment group, patients of female or age ≥ 65 years old showed higher rate of target BP achievement than relatively young male. (61.4 vs. 46.8%, p = .042) Our study showed standard dose triple combination of telmisartan 80 mg/amlodipine 5 mg/chlorthalidone 25 mg is efficacious and safe in treatment of primary hypertension. Target BP achievement with triple therapy would be facilitated in female or old age.

The brain is among the target organs of hypertension. Patients with hypertension have a higher risk of developing stroke as well as experiencing a decline in cognitive functions and dementia. Changes in the white matter and atrophy of the grey matter of the brain induced by high blood pressure develop insidiously since the onset of hypertension, even in young individuals. The effect of high blood pressure on the vessel wall cumulates in time; therefore, hypertension in younger people implies an increased risk of dementia in older age. Hypertension in young age cannot be considered a benign condition. Hypertension in middle age increases the risk of dementia by 61 %. Consistent and early hypertension control can reverse the adverse development towards dementia and lack of self-sufficiency in the patient. Data comparing individual antihypertensive drugs in terms of preventing dementia are scarce. However, renin angiotensin system blockers have been found to protect against Alzheimer's disease more than other classes of antihypertensive drugs. To achieve rapid and effective hypertension control, a combination of antihypertensive drugs is usually required. Using a fixed-dose triple combination of perindopril, indapamide, and amlodipine, blood pressure targets of < 130/80 mm Hg can be achieved within three months in 93 % of patients.

Aim: The objective of this study was the evaluation of the arterial stiffness, which changed after adding statins to the guidelines recommended dual or triple fixed combination antihypertensive therapy in patients with moderate to severe arterial hypertension. Materials and methods: It was included 99 patients in total being diagnosed with moderate and severe arterial hypertension (2nd and 3rd stages of arterial hypertension) without diabetes. Those patients were divided into 2 groups. The first group (n = 59) was assigned to the dual or triple fixed combination antihypertensive therapy plus including statins.Patients in the second group (n = 40) received only the dual or triple fixed combination antihypertensive treatment following the recommended guidelines without any statins. The CAVI index was performed in order to measure in all participants before and at the end of the follow-up period. Furthermore, the Office (Clinic BP) Blood Pressure (BP) was monitored in assigned participants as well as the Ambulatory Blood Pressure Monitoring (ABPM). The laboratory investigations also took place such as the standard blood test, the urine and biochemistry analysis and the estimated Carotid Intima-Media Thicknesses with Ultrasound. The study-duration was 6 months. Results: Office BP and ABPM had decreased significantly and equally in both treatment groups. The total cholesterol (TC) and LDL cholesterol had decreased significantly in the statin group on 1,76 mmol/l (30%, p < 0,05) and 1,51 mmol/l (41%, p < 0,05) respectively. In the group without statin therapy, there was no changes in the level of TC and LDL cholesterol. In the group without statins, it was noted a significant decrease in the level of BP, however, the CAVI index level was shown the growth to +0,9 units on the right side and +1,0 units on the left.In the group without statin's treatment, the CAVI index was changed from 7.73 ± 0.17/7.62 ± 0.19 units to 8.63 ± 0.22/8.62 ± 0.12 units on the right/left site after treatment (p < 0,05). It means there was an increase in the stiffness of the arterial wall in terms of cardio-vascular index CAVI in the group without added statin after 6 months of the therapy. In the group with added statin after 6 months of the therapy, the CAVI had not have any changes. It can be seen from the observed figures: the CAVI on the right/left site was 8.32 ± 0.16/8.33 ± 0.19 initially and 8.44 ± 0.16/8.24 ± 0.15 units treatment (p > 0,05) afterwards.We did not note any impact of statin therapy on the BP level. However, a significant correlations was found between the CAVI index with age and the serum level of blood Triglycerides before treatment, including LDL Cholesterol and HDL Cholesterol, duration of hypertension, the blood glucose level, the Potassium level and the Maximum Thickness of Intima-Media of Carotid Arteries in the statins group. Conclusion: The adding of the statin to the current fixed dual or triple combination of the antihypertensive therapy could prevent the progression of arterial stiffness in patients with 2nd and 3rd stages of arterial hypertension.
RESUMO
The approval of immune-checkpoint inhibitors (CPI) and mitogen activated protein kinase inhibitors (MAPKi) in recent years significantly improved the treatment management and survival of patients with advanced malignant melanoma. CPI aim to counter-act receptor-mediated inhibitory effects of tumor cells and immunomodulatory cell types on effector T cells, whereas MAPKi are intended to inhibit tumor cell survival. In agreement with these complementary modes of action preclinical data indicated that the combined application of CPI and MAPKi or their optimal sequencing might provide additional clinical benefit. In this review the rationale and preclinical evidence that support the combined application of MAPKi and CPI either in concurrent or consecutive regimens are presented. Further, we will discuss the results from clinical trials investigating the sequential or combined application of MAPKi and CPI for advanced melanoma patients and their implications for clinical practice. Finally, we outline mechanisms of MAPKi and CPI cross-resistance which limit the efficacy of currently available treatments, as well as combination regimens.

We report here how the triple combination of drugs elexacaftor/tezacaftor/ivacaftor (ETI) alters the balance of the de-novo synthethic pathway of sphingolipids in primary cells of human bronchial epithelium. The treatment with ETI roughly doubles the levels of dihydrosphingolipids, possibly by modulating the delta(4)-desaturase enzymes that convert dihydroceramides into ceramides. This appears to be an off-target effect of ETI, since it occurs in a genotype-independent manner, for both cystic fibrosis (CF) and non-CF subjects.

Paediatric acute myeloid leukaemia (AML) continues to present treatment challenges, as no "standard approach" exists to treat those young patients reliably and safely. Combination therapies could become a viable treatment option for treating young patients with AML, allowing multiple pathways to be targeted. Our in silico analysis of AML patients highlighted "cell death and survival" as an aberrant, potentially targetable pathway in paediatric AML patients. Therefore, we aimed to identify novel combination therapies to target apoptosis. Our apoptotic drug screening resulted in the identification of one potential "novel" drug pairing, comprising the Bcl-2 inhibitor ABT-737 combined with the CDK inhibitor Purvalanol-A, as well as one triple combination of ABT-737 + AKT inhibitor + SU9516, which showed significant synergism in a series of paediatric AML cell lines. Using a phosphoproteomic approach to understand the apoptotic mechanism involved, proteins related to apoptotic cell death and cell survival were represented, in agreement with further results showing differentially expressed apoptotic proteins and their phosphorylated forms among combination treatments compared to single-agent treated cells such upregulation of BAX and its phosphorylated form (Thr167), dephosphorylation of BAD (Ser 112), and downregulation of MCL-1 and its phosphorylated form (Ser159/Thr 163). Total levels of Bcl-2 were decreased but correlated with increased levels of phosphorylated Bcl-2, which was consistent with our phosphoproteomic analysis predictions. Bcl-2 phosphorylation was regulated by extracellular-signal-regulated kinase (ERK) but not PP2A phosphatase. Although the mechanism linking to Bcl-2 phosphorylation remains to be determined, our findings provide first-hand insights on potential novel combination treatments for AML.

Aim: Selexipag is an oral selective prostacyclin receptor agonist approved for treatment of patients with pulmonary arterial hypertension (PAH). In the present study, we aim to assess the safety and efficacy of selexipag in triple combination therapy with endothelial receptor antagonists (ERAs) and PDE5is for Chinese PAH patients. Methods and results: A single center retrospective study was performed on group 1 PAH patients (n = 68) initiating triple combination therapy with selexipag from 1 February 2020 to 31 August 2021 in Qilu Hospital of Shandong University (Shandong, China). Adolescents, children, and PAH patients with unrepaired congenital heart disease were excluded. The French pulmonary hypertension network (FPHN) non-invasive risk assessment, echocardiogram parameters, and clinical data, including tolerability, safety, and death/hospitalization events associated with PAH, were collected. Of the 68 patients, 31 (45.6%) patients had tolerable side effects while only a single patient discontinued selexipag due to severe diarrhea. In the analysis of the efficacy set of 62 patients, the median selexipag treatment time from selexipag initiation to last risk assessment was 27 (21, 33) weeks. Compared to baseline parameters, the percentage of WHO FC III/IV decreased from 77.4% (48) to 24.2% (15) (p = 0.000), median 6-min walk distance (6MWD) increased 82 m [from 398 (318, 450) to 480 (420, 506) m; p = 0.000], and NT-proBNP levels decreased from 1,216 (329, 2,159) to 455 (134, 1,678) pg/mL (p = 0.007). Patients who improved to three low-risk criteria increased from 9.7 to 38.7%. Right ventricular diameter (RV) diameter also decreased and was accompanied by an improved tricuspid annular plane systolic excursion (TAPSE). Patients transitioning from subcutaneous treprostinil to selexipag continued to show improvements in WHO FC, 6MWD (404 ± 94 vs. 383 ± 127 m) and NT-proBNP levels (2,319 ± 2,448 vs. 2,987 ± 3,770 pg/mL). Finally, the 1-year event free survival rate was 96.7% for patients initiating the triple combination therapy within 3 years of PAH diagnosis. Conclusion: Triple combination therapy with selexipag was safe and effective in Chinese PAH patients, which was confirmed by acceptable tolerability, and improved exercise capacity, right heart function, risk assessment, and prognosis.
RESUMO
This study aimed to assess and compare the clinical efficacy and safety of a triple combination treatment using 2940 nm Er:YAG laser, triamcinolone acetonide solution combined with either 308 nm excimer laser or 0.1% tacrolimus for the treatment of stable segmental vitiligo. Patients with stable segmental vitiligo were randomly divided into two groups and received a 5-month treatment with 2940 nm Er:YAG laser followed by triamcinolone acetonide and, either 308 nm excimer laser (Group A, N = 8) or 0.1% tacrolimus (Group B, N = 13). General information and imaging data were collected before and at 1 month after treatments. Marked repigmentation and overall repigmentation rates were analyzed and any adverse skin reactions were recorded. Both treatments significantly reduced the percent of skin lesions per total body surface area (p < 0.05) and no significant differences in repigmentation were observed between the two groups (p > 0.05). The marked repigmentation rate of Group A was 42.11% and overall repigmentation rate was 94.74%, while for Group B these rates were 51.16% and 100%, respectively. There were no significant differences in the number of fingertip units at each time point (p > 0.05). While there was a significant effect for time on the number of fingertip units without considering other factors (p < 0.05), the time x treatment interaction was not significant (p > 0.05). One Group A patient developed adverse reactions consisting of erythema, burning sensation and blisters and one Group B patient developed mild erythema and burning sensations. Both treatments demonstrated a high level of efficacy and safety in the treatment of stable segmental vitiligo.

Introduction Topical medications are one of the most commonly used therapeutic agents in treating a wide spectrum of dermatological diseases. The misuse of topical medicines for inappropriate indications and an extended period may result in cutaneous adverse drug reactions (ADR). Aims We conducted this study to observe demographic parameters, commonly misused topical medicines, various clinical patterns of cutaneous ADR, and source of drug prescription among study participants. Materials and methods This cross-sectional observational study was conducted from October 2021 to May 2022 at the dermatology outpatient department (OPD) of a tertiary care center. All patients who presented with worsening pre-existing skin diseases or the development of skin disease after the topical application of some cream or ointment were included in the study with written informed consent. A detailed history was taken, and a clinical examination was done. Results We detected 200 cases (1.62%) of cutaneous ADR out of 12,346 OPD patients in the eight-month study period. The most common age group was 21-30 years (30%). Most of the patients had used topical medicines for fungal infections (76%). The most commonly used topical medication was a fixed drug combination (FDC) of steroid, antifungal, and antibacterial agents (40%). Tinea incognito (36%) was the most common cutaneous ADR noted. Conclusion This study shows that misuse of topical medications is rampant in our community because of their free and easy availability. There is an urgent requirement for strict regulations over the manufacturing, sales, and marketing of over-the-counter (OTC) topical medications to reduce the incidence of cutaneous ADR.
RESUMO
The ongoing crisis of antimicrobial resistance demands novel combinations between antimicrobials and nonantimicrobials to manage infections caused by highly resistant pathogens. This study aimed to evaluate the effect of combining sodium ascorbate and/or apo-transferrin with imipenem, forming double and triple combinations, against 20 multiple-carbapenemase-producing Acinetobacter baumannii strains using the checkerboard test, time-kill assay, and disc diffusion test. The results of the checkerboard assay revealed that all double combinations showed indifference, while only triple combination recorded a synergistic effect (fractional inhibitory concentration index [FICI] < 0.8) in 95% the test isolates. Moreover, the MIC of imipenem (MICimp) was strongly reduced (up to 128-fold reduction) after treatment with the triple combination against highly resistant isolates and reached the susceptible range. The time-kill assay revealed that the triple combination led to a 4-log10 reduction in the CFU at 8 h compared with the initial bacterial count, and no viable count was recorded at 10 h. The mouse pneumonia model showed restoration of lung function and structure, with mild to moderate residual inflammation and moderately congested vessels observed 8 h following administration of the triple rescue therapy. Additionally, normal lungs with normal patent alveoli were detected 72 h following treatment. Accordingly, sodium ascorbate and apo-transferrin are promising adjunct biological agents with the potential to restore the effectiveness of critically essential antibiotics like imipenem, commonly used for the treatment of A. baumannii infections. IMPORTANCE Combination therapy provides a perspective to threat multidrug-resistant (MDR) strains. The present study sheds light on a novel and effective triple combination against carbapenem-resistant A. baumannii. Our in vitro results showed that combining imipenem with apo-transferrin and sodium ascorbate yielded synergism in 95% of test isolates, and this was associated with a marked reduction in imipenem MIC, shifting it below the breakpoint. Furthermore, a bactericidal effect was recorded, with no viable count detected at 10 h. An in vivo murine model of pneumonia was induced to mimic human disease. The triple combination therapy restored lung function and structure, with mild to moderate residual inflammation and moderately congested vessels observed 8 h following the initiation of therapy. Therefore, our findings suggest novel insights about a promising new combination therapy against highly resistant carbapenemase-producing A. baumannii to restore the effectiveness of imipenem.

Introduction: Inhaled corticosteroid/long-acting ß2-adrenoceptor agonist/long-acting muscarinic antagonist (ICS/LABA/LAMA) fixed-dose combination (FDC) is currently recommended as controller option at asthma Step 4 and as preferred treatment at asthma Step 5, but no research investigated the potential drawbacks of this therapeutic option in a large asthmatic population. Thus, the aim of this study was to quantify the potential drawbacks of triple FDC therapy in asthma. Methods: A pairwise meta-analysis was performed according to PRISMA-P guidelines to assess the risk of overall serious adverse events (SAEs), cardiovascular SAEs, and pneumonia reported as SAE in asthmatic patients treated with ICS/LABA/LAMA FDC vs ICS/LABA FDC. A pooled analysis was performed to calculate the frequency of SAEs. Results: Data from 7204 asthmatic patients were extracted from the CAPTAIN, IRIDIUM, TRIMARAN, and TRIGGER studies. Triple FDC vs ICS/LABA FDC did not increase the risk of total SAEs (RR 0.99 95% CI 0.83-1.18) and cardiac SAEs (RR 0.74 95% CI 0.39-1.40), whereas the sensitivity analysis performed to resolve heterogeneity resulted in increased risk of vascular SAEs (RR 3.23 95% CI 1.05-9.90, P<0.05). The level of ICS dose did not modulate the risk of pneumonia, in any case pneumonia was the most frequent SAE (0.57%). These results were not affected by significant risk of bias. Conclusion: Triple FDC is a safe pharmacological therapy in severe asthmatic patients; it is characterized by a favourable safety profile and few potential drawbacks, namely, the increased risk of vascular SAEs, that certainly are worthy of future investigations.
