Al Bazzal A, Hatami P, Abedini R, Etesami I, Ayanian Z, Ghandi N. A prospective comparative study of two regimens of diphenylcyclopropenone (DPCP) in the treatment of alopecia areata. Int Immunopharmacol 2021; 101:108186. [PMID: 34710658 DOI: 10.1016/j.intimp.2021.108186] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 09/19/2021] [Accepted: 09/20/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Alopecia areata (AA) is a chronic disorder and the best treatment regimen for it is unknown. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. AIM To evaluate the safety and efficacy of a novel method (multi-concentration patch test) versus standard protocol for topical immunotherapy. METHODS A prospective randomized clinical trial was conducted on 30 patients with Alopecia areata, half of them received DPCP with a novel method using multi-concentration patch test to determine the optimal initiating concentration of DPCP (case group) and the other half experienced immunotherapy according to the standard protocol (control group). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. (IRCT registration code: IRCT20141209020250N5). RESULTS Absolute and relative hair regrowth percentages were reported 25% and 41.49% in case group and 8.2% and 14.21% in control group respectively. Considerable response (more than 75% hair regrowth) was observed in 4 (26.6%) patients in case and 1 (6.6%) patient in control group. The clinical response was initiated about 7 weeks sooner in case compared to the control group (14 versus 7.38 weeks, P: 0.001). Overall, clinical response was higher in patients received new protocol, compared to control group. Moreover, patients who experienced new protocol had a higher level of treatment satisfaction in comparison with patients having standard protocol (P: 0.012). CONCLUSION This study revealed the effectiveness and safety of the novel multi-concentration patch test DPCP therapy for AA and its priority to conventional method, at least in terms of shortened duration of DPCP immunotherapy.

Abstract
BACKGROUND Alopecia areata (AA) is a chronic autoimmune disorder. Finding the best treatment regimen for it remains a challenge. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. AIM To evaluate the safety and efficacy of combined DPCP and anthralin versus standard protocol (DPCP alone). METHODS A prospective randomized clinical trial was conducted on 50 patients with Alopecia areata who received DPCP alone (group D) or in combination with anthralin (group D/A). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. RESULTS Complete hair regrowth was observed among three patients in each group (18.75% in Group D and 15.79% in Group D/A) after 6 months. Moreover, 25% and 31% of patients in group D and 21% and 47% of patients in group D/A had > 75% and > 50% hair regrowth respectively at the end of the study (P-value: 0.696). In addition, earlier age of onset, chronicity of lesions, nail involvement, facial hair loss and extensive lesions at baseline were associated with poor clinical outcome. CONCLUSION DPCP and anthralin was as effective as DPCP alone and anthralin did not add to the effect of DPCP in treating AA.

Abstract
The nervous system, which consists of a complex network of millions of neurons, is one of the most highly intricate systems in the body. This complex network is responsible for the physiological and cognitive functions of the human body. Following injuries or degenerative diseases, damage to the nervous system is overwhelming because of its complexity and its limited regeneration capacity. However, neural tissue engineering currently has some capacities for repairing nerve deficits and promoting neural regeneration, with more developments in the future. Nevertheless, controlling the guidance of stem cell proliferation and differentiation is a challenging step towards this goal. Nanomaterials have the potential for the guidance of the stem cells towards the neural lineage which can overcome the pitfalls of the classical methods since they provide a unique microenvironment that facilitates cell-matrix and cell-cell interaction, and they can manipulate the cell signaling mechanisms to control stem cells' fate. In this article, the suitable cell sources and microenvironment cues for neuronal tissue engineering were examined. Afterward, the nanomaterials that impact stem cell proliferation and differentiation towards neuronal lineage were reviewed.

Abstract
OBJECTIVES Existing studies have demonstrated that intravenous and intramyocardial-administrated mesenchymal stem cells (MSCs) lead to tissue repair after cardiac disorders. We compared the efficiency of both administration methods. MATERIALS AND METHODS A rat model of isoproterenol-induced heart failure (ISO-HF) was established to compare the effects of intravenous and intramyocardial-administrated MSCs on cardiac fibrosis and function. The animals were randomly assigned into six groups: i) control or normal, ii) ISO-HF (HF) iii) ISO-HF rats treated with intramyocardial administration of culture medium (HF+IM/CM), iv) ISO-HF rats treated with intravenous administration of culture medium ( HF+IV/CM), v) ISO-HF rats treated with intravenous administration of MSCs (HF+IV/MSCs), vi) ISO-HF rats treated with intramyocardial administration of MSCs ( HF+IM/MSCs). Cultured MSCs and culture medium were administrated at 4 weeks after final injection of ISO. Heart function, identification of MSCs, osteogenic differentiation, adipogenic differentiation, cardiac fibrosis and tissue damage were evaluated by echocardiography, flow-cytometery, von Kossa, oil red O, Masson's trichrome and H & E staining, respectively. RESULTS Both intravenous and intramyocardial MSCs therapy significantly improved heart function and reduced cardiac fibrosis and tissue damage (P<0.05), whereas the cultured medium had no beneficial effects. CONCLUSION In sum, our results confirm the validity of both administration methods in recovery of HF, but more future research is required.

Abstract
Hydrogels are a three-dimensional and crosslinked network of hydrophilic polymers. They can absorb a large amount of water or biological fluids, which leads to their swelling while maintaining their 3D structure without dissolving (Zhu and Marchant, Expert Rev Med Devices 8:607-626, 2011). Among the numerous polymers which have been utilized for the preparation of the hydrogels, polysaccharides have gained more attention in the area of pharmaceutics; Sodium alginate is a non-toxic, biocompatible, and biodegradable polysaccharide with several unique physicochemical properties for which has used as delivery vehicles for drugs (Kumar Giri et al., Curr Drug Deliv 9:539-555, 2012). Owing to their high-water content and resembling the natural soft tissue, hydrogels were studied a lot as a scaffold. The formation of hydrogels can occur by interactions of the anionic alginates with multivalent inorganic cations through a typical ionotropic gelation method. However, those applications require the control of some properties such as mechanical stiffness, swelling, degradation, cell attachment, and binding or release of bioactive molecules by using the chemical or physical modifications of the alginate hydrogel. In the current review, an overview of alginate hydrogels and their properties will be presented as well as the methods of producing alginate hydrogels. In the next section of the present review paper, the application of the alginate hydrogels will be defined as drug delivery vehicles for chemotherapeutic agents. The recent advances in the application of the alginate-based hydrogels will be describe later as a wound dressing and bioink in 3D bioprinting.

The Synergistic Effect of Glucagon-Like Peptide-1 and Chamomile Oil on Differentiation of Mesenchymal Stem Cells into Insulin-Producing Cells. CELL JOURNAL 2020; 21:371-378. [PMID: 31376318 PMCID: PMC6722451 DOI: 10.22074/cellj.2020.6325] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Accepted: 11/17/2018] [Indexed: 01/01/2023]
Abstract
OBJECTIVE Glucagon-like peptide-1 (GLP-1) has attracted tremendous attention for treatment of diabetes. Likewise, it seems that active ingredients of chamomile oil might have anti-diabetic effects. This work was conducted to investigate the effects of the combination of GLP-1 and chamomile oil on differentiation of mesenchymal stem cells (MSCs) into functional insulin-producing cells (IPCs). MATERIALS AND METHODS In this experimental study, adipose MSCs derived from the adult male New Zealand white rabbits were assigned into four groups: control (without any treatment); GLP-1 (in which cells were treated with 10 nM GLP-1 every other day for 5 days); chamomile oil (in which cells were treated with 100 ug/ml Matricaria chamomilla L. flower oil every other day for 5 days); and GLP-1+ chamomile oil (in which cells were treated with 10 nM GLP-1 and 100 μg/ml M. chamomilla flower oil every other day for 5 days). Characterization of isolated MSCs was performed using flow cytometry, Alizarin red S staining and Oil red O staining. The expressions of genes specific for IPCs were measured using reverse transcriptase-polymerase chain reaction (RT-PCR) assay. Measurement of insulin and the cleaved connecting peptide (C-peptide) in response to different concentrations of glucose, were performed using ELISA kits. RESULTS Our results demonstrated that isolated cells highly expressed MSC markers and were able to differentiate into osteocytes and adipocytes. Additionally, using GLP-1 in combination with chamomile oil exhibited higher levels of IPCs gene markers including NK homeobox gene 2.2 (NKX-2.2), paired box gene 4 (PAX4), insulin (INS) and pancreatic duodenal homeobox-1 (PDX1) as well as insulin and C-peptide secretion in response to different glucose concentrations compared to GLP-1 or chamomile oil alone (P<0.05). CONCLUSION Collectively, these findings establish a substantial foundation for using peptides in combination with natural products to obtain higher efficiency in regenerative medicine and peptide therapy.

Abstract
Aim: Routine therapeutic drug monitoring is highly recommended since common antidepressant combinations increase the risk of drug-drug interactions or overlapping toxicity. Materials & methods: A magnetic solid-phase extraction by using C18-functionalized magnetic silica nanoparticles (C18-Fe3O4@SiO2 NPs) as sorbent was proposed for rapid extraction of venlafaxine, paroxetine, fluoxetine, norfluoxetine and sertraline from clinical plasma and urine samples followed by ultra-HPLC-MS/MS assay. Results: The synthesized C18-Fe3O4@SiO2 NPs showed high magnetization and efficient extraction for the analytes. After cleanup by magnetic solid-phase extraction, no matrix effects were found in plasma and urine matrices. The analytes showed LODs among 0.15-0.75 ng ml-1, appropriate linearity (R ≥ 0.9990) from 2.5 to 1000 ng ml-1, acceptable accuracies 89.1-110.9% with precisions ≤11.0%. The protocol was successfully applied for the analysis of patients' plasma and urine samples. Conclusion: It shows high potential in routine therapeutic drug monitoring of clinical biological samples.

Abstract
PURPOSE A potential therapeutic approach on skin flap necrosis is to target parallel pathways involved in necrosis. Azelaic Acid, Minoxidil and Caffeine combination was tried on skin flap survival by their possible interaction with ATP sensitive potassium (KATP) channels and nitric oxide pathway. MATERIAL AND METHODS Sprauge-Dawley rats were divided into 8 groups for skin flap surgery. Azelaic acid, minoxidil, caffeine, or their combination were applied topically in different groups. Two additional groups were treated with L-NAME or glibenclamide in addition to the combination therapy. Percentage of flap necrosis was calculated and flap samples were removed to measure tissue malondialdehyde (MDA) and nitric oxide (NO) and expression of inducible nitric oxide synthase (iNOS), Bcl-2 and Bax proteins. RESULTS Combination therapy profoundly decreased skin flap necrosis, tissue MDA contents, and expression of the pro-apoptotic protein Bax (p < 0.05 vs. single treatments). These effects were reversed by L-NAME and glibenclamide pre-treatments. Further evaluations showed combination therapy increases flap tissue NO content and iNOS expression (p < 0.05 vs. single treatments). CONCLUSION Beneficial effect of the combination therapy with azelaic acid, minoxidil and caffeine therapy on rescuing the flap from necrosis by targeting parallel signaling pathways suggested potential applications in clinical practice.

Abstract
Presently, clinical nanomedicine and nanobiotechnology have impressively demanded the generation of new organic/inorganic analogues of graphene (as one of the intriguing biomedical research targets) for stem-cell-based tissue engineering. Among different shapes of graphene, three-dimensional (3D) graphene foams (GFs) are highly promising candidates to provide conditions for mimicking in vivo environments, affording effective cell attachment, proliferation,and differentiation due to their unique properties. These include the highest biocompatibility among nanostructures, high surface-to-volume ratio, 3D porous structure (to provide a homogeneous/isotropic growth of tissues), highly favorable mechanical characteristics, and rapid mass and electron transport kinetics (which are required for chemical/physical stimulation of differentiated cells). This review aims to describe recent and rapid advances in the fabrication of 3D GFs, together with their use in tissue engineering and regenerative nanomedicine applications. Moreover, we have summarized a broad range of recent studies about the behaviors, biocompatibility/toxicity,and biodegradability of these materials, both in vitro and in vivo. Finally, the highlights and challenges of these 3D porous structures, compared to the current polymeric scaffold competitors, are discussed.

Abstract
OBJECTIVE The mesenchymal stem cells derived from human amniotic membrane have the ability to secrete and release some factors that can promote the repair of damaged tissues. This secretome contains proteins and factors that reduce apoptosis and increase angiogenesis in the ischemia/reperfusion models. The present study was conducted to determine whether this secretome provides protection against transient focal cerebral ischemia. MATERIALS AND METHODS A rat model of focal cerebral ischemia was established through middle cerebral artery occlusion (MCAO) for 60 min and 24 h reperfusion. The amniotic mesenchymal stem cells-conditioned medium (AMSC-CM) at the dose of 0.5 μl was injected intracerebroventriculary (ICV) 30 min after reperfusion. Infarct volume, brain edema, neurobehavioral functions, and blood brain barrier (BBB) integrity were assessed 24 h after reperfusion. Neuronal loss and expression of caspase-3, Bax and Bcl-2 in motor cortex were evaluated by nissl staining and immunohistochemistry assay respectively. RESULTS ICV administration of AMSC-CM markedly reduced infarct volume, brain edema and the evans blue penetration rate compared with MCAO group (P < 0.05). Additionally, post-treatment with AMSC-CM significantly reduced neuronal loss, neurological motor disorders and expression of caspase-3, Bax and Bcl-2 in motor cortex compared with MCAO group (P < 0.05). CONCLUSION The results of this study indicate that treatment with AMSC-CM improves the pathological effects in the acute phase of cerebral ischemia. These findings establish a substantial foundation for stroke therapy and future research.

Abstract
INTRODUCTION Topical immunotherapy is frequently used in the treatment of alopecia areata (AA) although few studies report long-term follow-up. Our goals were to determine the efficacy and the prognostic factors of topical immunotherapy in a large cohort of patients with AA treated in the departments of Dermatology and Venereology of Bergamo, Como and Pavia, from 1978 to January 2016. METHODS A total of 252 patients with AA were evaluated retrospectively. RESULTS All our patients developed an allergic reaction to a 2% solution of dinitrochlorobenzene (DNCB) or squaric acid dibutylester (SADBE) or diphenylcyclopropenone (DPCP). No patients discontinued therapy because of side effects. In total 112 patients (44.05%, p < 0.001) had a good response. Statistical analysis revealed that the main prognostic factors influencing the clinical results were the severity of hair loss at the beginning of therapy, the duration of AA, a history of atopy (particularly eczema), and the early development of sensitization to the three sensitizers. CONCLUSION Topical immunotherapy in patients with AA is quite effective, mostly well tolerated, and provides prolonged therapeutic benefits.

Abstract
Testicular torsion-related oxidative stress causes a sequential chain of DNA damage, lipid peroxidation and cell death that leads to the derangement in the sperm functions and infertility. Capsaicin that has been applied for pain relief and cancer prevention possesses antioxidant properties which can be exploited to confer cell survival under ischaemic testis damage. Wistar male rats weighing 150-200 g were randomly divided into four groups: (i) sham group (all procedures except torsion of testis), (ii) ischaemia group (TT group), (iii) three TT groups treated with different dose of capsaicin (TT + different doses of Cap) and (iv) three control groups treated with different doses of capsaicin (100, 500 and 1000 ug/ml). Capsaicin administration significantly decreased the expression of pro-apoptotic factors and increased the expression of anti-apoptotic factors. Likewise, the expression of FOXO1 is significantly increased by higher doses of the capsaicin. Histological assessment by H&E and TUNEL method also exhibited an improved testicular morphology and decreased apoptosis in testes. These results suggested clinical potential for capsaicin in treatment of testicular torsion by targeting FOXO1 and apoptotic pathways.

Abstract
Diphenylcyclopropenone (DPCP) is an effective topical immunotherapy for recalcitrant alopecia areata (AA), which sometimes requires prolonged treatment. We developed a new treatment protocol to shorten the duration of therapy. This study aimed to compare the efficacy and safety of the new treatment protocol with the standard treatment protocol in the treatment of recalcitrant AA. We conducted a 6-year retrospective comparative study of patients with AA who received one of the DPCP treatment protocols at our institute. Patients’ information was collected and subsequent statistically analyzed. Thirtynine patients (16 in the new treatment group and 23 in the standard treatment group) were included. There were no statistically significant differences in area of hair regrowth. Mean duration to initial hair regrowth and mean duration to significant hair regrowth in the new treatment group were significantly shorter than in the standard treatment group (P=0.002 and 0.01, respectively). Adverse effects were slightly higher in the new treatment group. The present study reveals the effectiveness and safety of the new treatment protocol, which shortens the duration of DPCP treatment and could represent an alternative regimen.

Abstract
BACKGROUND Although diphenylcyclopropenone (DCP) is frequently used for the treatment of alopecia areata (AA), large studies with more than 100 patients are still scarce. OBJECTIVE To determine the efficacy of DCP immunotherapy in a large cohort of patients with AA who had been treated in our institute from January 2000 to December 2006. METHODS A total of 142 patients with AA undergoing topical DCP therapy in a self-controlled design were evaluated retrospectively. RESULTS Seven patients (4.9%) were anergic to DCP. Two of 135 patients (1.5%) discontinued DCP therapy because of adverse effects. Fifty-one patients (37.8%) had a complete response (CR: >90% re-growth of hair), 20 patients (14.8%) exhibited a partial response (PR: >50-90% re-growth), 26 patients (19.3%) experienced a minimal response (MR: 10-50% re-growth) and 38 patients (28.1%) had no response after DCP therapy (NR: <10% re-growth). Bivariate logistic analysis revealed that severity of hair loss at the beginning of DCP (P=0.001) is the only significant prognostic factor for therapeutic outcome. Twenty-three patients (45.1%) with CR had relapses upon discontinuation of the treatment or even during prolonged DCP therapy. CONCLUSION Topical immunotherapy with DCP of patients with AA is rather effective and mostly well tolerated. The extent of hair loss before therapy is the main predictor for the therapeutic success of DCP. However, DCP therapy is associated with a high degree of relapse of which patients should be well informed.

Abstract
OBJECTIVE To evaluate the efficacy of two topically applied immunomodulative agents through the detection of lymphocyte subsets using monoclonal antibodies against CD4, CD8 and MHC II. METHODS Fifty patients from the Departments of Medical Biochemistry, Dermatology and Pathology at Cairo University with different degrees of alopecia areata (AA) were included in this study. They were classified into two groups each of 25 patients. Each patient was treated with the immunomodulative agent on one side of the scalp and the other side was left as a control. Biopsies were taken from all patients at the beginning of treatment and at the end of the study. Tissue specimens were prepared for histologic and immunophenotypic analysis. The main outcome measures were the uses of diphencyprone (DPCP) and topical tacrolimus as two topical immunotherapeutic modalities in the treatment of AA. RESULTS A clinical response of 68% was achieved in group A (treated with DPCP) while group B (treated with 0.1% tacrolimus) showed an insignificant clinical response. Decreased expression of CD4 and increased expression of CD8 and MHC II was detected in the post-treated areas compared with pretreated areas in cases treated with DCPC. In tacrolimus-treated cases, there was a decrease in CD4 and MHC II, with no change in CD8 between the pre- and post-treated areas. CONCLUSION DCPC is one of the most accepted therapeutic modalities in the treatment of AA, with a favourable prognosis among patchy hair loss. MHC II expression was the one correlating with clinical response. Tacrolimus, though beneficial in other dermatoses, could not be considered effective in the treatment of AA.

Abstract
BACKGROUND Clinical efficacy of topical corticosteroids in alopecia areata (AA) is still controversial. Positive clinical results have been obtained using ointments with occlusive dressing but this approach has a low patient compliance. Recently, a new topical formulation (thermophobic foam: Versafoam) of clobetasol propionate 0.05% has been introduced on the market (Olux, Mipharm, Milan, Italy) (CF). This formulation is easy to apply. After application to the skin the foam quickly evaporates without residues and it has a good patient compliance. In vitro studies have also shown that this formulation enhances the delivery of the active compound through the skin. AIM To evaluate the efficacy, safety and tolerability of CF in the treatment of moderate to severe AA. SUBJECTS AND METHODS Thirty-four patients with moderate to severe AA (eight men, mean age 40+/-13 years) were enrolled in a randomized, double-blind, right-to-left, placebo-controlled, 24-week trial. Alopecia grading score (AGS) was calculated at baseline and after 12 and 24 weeks of treatment using a 0-5 score (0=no alopecia; 5=alopecia totalis). Clobetasol foam and the corresponding placebo foam (PF) were applied twice a day for 5 days/week for 12 weeks (phase 1) using an intrapatient design (right vs. left). From weeks 13 to 24 each enrolled patient continued only with the treatment (both on the right and left site) that was judged to have a greater efficacy than that on the contralateral side (phase 2). The primary outcome of the trial, evaluated on an intention-to-treat basis, was the hair regrowth rate, which was evaluated using a semiquantitative score (RGS) (from 0: no regrowth, to 4: regrowth of 75%). RESULTS At baseline the AGS was 4.1 (range: 2-5). Nine (26%) patients prematurely concluded the trial. At the end of phase 1, a greater hair regrowth was observed in 89% of the head sites treated with CF vs. 11% in the sites treated with PF. The RGS was 1.2+/-1.6 in the CF-treated sites and 0.4+/-0.8 in the PF-treated sites (P=0.001). A RGS of 2 (hair regrowth of more than 25%) was observed in 42% CF-treated sites and in 13% of PF-treated sites (P=0.027). In seven subjects (20%) a RGS of 3 to 4 (hair regrowth of 50%) was observed in CF-treated sites. In three subjects (9%) a RGS of 4 (hair regrowth of 75%) was observed in CF-treated sites. In one patient only, in a PF-treated region, a RGS of 3 was observed. The AS was reduced to 3.8 by CF treatment at the end of phase 1 and to 3.3 at the end of phase 2 (P=0.01). From weeks 12 to 24 the treatment with CF induced a further increase in the RGS (from 1.2 to 1.5+/-1.4). Forty-seven per cent of CF-treated patients had a RGS of 2 at the end of the trial. A total of eight patients (25%) at the end of the treatment with CF showed a RGS of 3. Folliculitis occurred in two patients. No significant modifications in cortisol and ACTH blood levels were observed during the trial. CONCLUSION This new formulation of clobetasol propionate foam is an effective, safe and well-tolerated topical treatment for AA. This formulation has a good cosmetic acceptance and patient compliance profile.
