The article discusses the current state of the problem and priorities in the treatment of chronic anal fissures according to literature data. We described consistently standard medical, surgical and other treatment methods with an assessment of their advantages and disadvantages. Based on the analysis of literature data, it is shown that fissure excision in combination with dosed form of subcutaneous sphincterotomy still remains the «gold standard» for the treatment of chronic anal fissure. Taking into account the revision of the traditionally established paradigm and the emerging trends towards a multidisciplinary approach to the problem, the use of combined and minimally invasive sphincter-sparing treatment methods is justified. The use of botulinum toxin, various options for anoplasty, transcutaneous neurostimulation, laser vaporization and pneumoballoon dilatation of the anal sphincter are described. The possibilities of using autologous plasma enriched with platelet growth factors and autologous cells of adipose origin used as cell (tissue) transplantation are presented.

Background: A prospective observational study was conducted with the purpose of evaluating the role of autologous platelet-rich plasma (PRP) in the form of a clot as an adjunct in surgery for the closure of large full-thickness macular holes (>400 µm). Methodology: Thirteen patients with a diagnosis of full-thickness macular hole larger than 400 µm, without associated pathologies or previous vitreoretinal surgeries, were selected. Each patient underwent a complete ophthalmological evaluation, including visual acuity (uncorrected or best corrected), optical coherence tomography (OCT Optovue), and in some cases, retinal photographs. On the day of the procedure, blood samples were taken to prepare PRP and form a clot according to institutional protocol. Patients were followed for 1 year with periodic evaluations that included OCT, retinal photographs, and assessments by a retina specialist and optometry. Results: Of the 13 patients, 46% (6 cases) had an epiretinal membrane as the triggering factor for the macular hole and 54% (7 cases) had vitreomacular traction. Complete closure of the macular hole was achieved in 92.31% (12 cases) and partial closure in 7.69% (1 case). Postoperative best-corrected visual acuity ranged from 20/30 to 20/200 according to the Snellen chart. No patient experienced a deterioration in visual acuity after the procedure. Conclusions: The use of PRP as an adjunct treatment for macular hole surgery in patients without previous vitreoretinal surgeries has proven to be effective in achieving complete or partial closure in a high percentage of cases. Pre-and postoperative changes in visual acuity, hole size, and type of closure provide valuable information on the efficacy of PRP treatment in these patients. [ABSTRACT FROM AUTHOR]

Background: Postoperative air leak (PAL) is a frequent and potentially serious complication following thoracic surgery, characterized by the persistent escape of air from the lung into the pleural space. It is associated with extended hospitalizations, increased morbidity, and elevated healthcare costs. Understanding the mechanisms, risk factors, and effective management strategies for PAL is crucial in improving surgical outcomes. Aim: This review seeks to synthesize all known data concerning PAL, including its etiology, risk factors, diagnostic approaches, and the range of available treatments from conservative measures to surgical interventions, with a special focus on the use of autologous plasma. Materials and Methods: A comprehensive literature search of databases such as PubMed, Cochrane Library, and Google Scholar was conducted for studies and reviews published on PAL following thoracic surgery. The selection criteria aimed to include articles that provided insights into the incidence, mechanisms, risk assessment, diagnostic methods, and treatment options for PAL. Special attention was given to studies detailing the use of autologous plasma in managing this complication. Results: PAL is influenced by a variety of patient-related, surgical, and perioperative factors. Diagnosis primarily relies on clinical observation and imaging, with severity assessments guiding management decisions. Conservative treatments, including chest tube management and physiotherapy, serve as the initial approach, while persistent leaks may necessitate surgical intervention. Autologous plasma has emerged as a promising treatment, offering a novel mechanism for enhancing pleural healing and reducing air leak duration, although evidence is still evolving. Conclusions: Effective management of PAL requires a multifaceted approach tailored to the individual patient's needs and the specifics of their condition. Beyond the traditional treatment approaches, innovative treatment modalities offer the potential to improve outcomes for patients experiencing PAL after thoracic surgery. Further research is needed to optimize treatment protocols and integrate new therapies into clinical practice. [ABSTRACT FROM AUTHOR]

Purpose: to evaluate the effectiveness of anti-scar treatment of eyelid tissues with platelet-rich plasma (PRP) lysate by pathomorphological examination. Material and methods. 20 patients (men aged 27–64 years with eyelid scars caused by traumatic tissue rupture) underwent reconstructive plastic surgery on their eyelids. All patients had similar injuries and traumatic agents, the type and localization of the scar, and the same duration of the post-traumatic period (12 months after the injury). The patients were divided into 2 groups depending on the application of anti-scar treatment using PRP lysate in the preoperative period. The treatment consisted in injecting a personalized biotransplant into the scar tissue. During the surgery, a fragment of scar tissue was taken from each patient for pathomorphological examination. Results. In the control group, the pathomorphological picture was of the same type and corresponded to the third phase of wound healing with remodeling and the formation of a rough scar. The third phase of wound healing with scar remodeling in patients of the main group was characterized by significantly less pronounced fibrotic-dystrophic changes in both cellular and stromal components of the dermis and hypodermis. Conclusion. In the main group with PRP lysate therapy, scar tissue was characterized by significantly less pronounced fibrotic-dystrophic changes in both cellular and stromal components of the dermis and hypodermis as compared to the control group. The observed morphological picture was close to a complete involution of the scar with its restructuring, approaching the normal histoarchitectonics of the dermis and hypodermis.

Most of the current assays directed at the investigation of HIV reactivation are based on cultures of infected cells such as Peripheral Blood Mononuclear Cells (PBMCs) or isolated CD4+ T cells, stimulated in vitro with different activator molecules. The culture media in these in vitro tests lack many age- and donor-specific immunomodulatory components normally found within the autologous plasma. This triggered our interest in understanding the impact that different matrices and cell types have on T cell transcriptional profiles following in vitro culture and stimulation. Methods: Unstimulated or stimulated CD4+ T cells of three young adults with perinatal HIV-infection were isolated from PBMCs before or after culture in RPMI medium or autologous plasma. Transcriptomes were sequenced using Oxford Nanopore technologies. Results: Transcriptional profiles revealed the activation of similar pathways upon stimulation in both media with a higher magnitude of TCR cascade activation in CD4+ lymphocytes cultured in RPMI. Conclusions: These results suggest that for studies aiming at quantifying the magnitude of biological mechanisms under T cell activation, the autologous plasma could better approximate the in vivo environment. Conversely, if the study aims at defining qualitative aspects, then RPMI culture could provide more evident results. [ABSTRACT FROM AUTHOR]

Objective To explore the clinical effects of autologous platelet-rich plasma (PRP) in the treatment of postoperative bone nonunion for long bone shaft fractures during operation and after operation. Methods A total of 34 patients with postoperative bone nonunion for long bone shaft fracture, who were admitted and cured in the Orthopedics Department of our hospital from January 2019 to June 2020, were selected. They were randomly divided into the experimental group(n=17) and control group(n=17). Individuals in the control were treated with autologous iliac bone alone., while the experimental group were treated with autologous iliac bone graft plus autologous PRP during and after operation. After surgery, the autogenous PRP was accurately injected with ultrasound guidance every 7 days (5 mL/person, 4 occasions in total). The clinical healing time of the fracture, the grading of callus formation and the functional rehabilitation level of limbs on the affected side at different time were observed in both groups. Results All 34 patients were followed up. In the experimental group and the control group, the clinical healing time (month) of the fracture was (5.03±1.24) vs (6.91±1.41), P

Abstract Background Although umbilical cord blood (UCB) is identified as a source of mesenchymal stem cells (MSCs) with various advantages, the success in cell isolation is volatile. Therefore, it is necessary to optimize methods of cord blood-derived MSC (UCB-MSC) isolation and culture. In this study, we evaluated the efficiency of UCB-MSC isolation and expansion using different commercially available serum- and xeno-free media and investigated the capacity of autologous serum and plasma as a supplement to support cell proliferation. Additionally, we defined the presence of multilineage-differentiating stress-enduring (Muse) cells in the UCB-MSC population. Functions of UCB-MSC in in vitro angiogenesis processes and anti-cancer were also verified. Methods Mononuclear cells were isolated using density gradient separation and cultured in four commercial media kits, as well as four surface coating solutions. UCB-MSCs were characterized and tested on tube formation assay, and co-cultured with SK-MEL cells in a transwell system. Results The results showed that only StemMACS™ MSC Expansion Media is more appropriate to isolate and culture UCB-MSCs. The cells exhibited a high cell proliferation rate, CFU forming capability, MSC surface marker expression, trilineage differentiate potential, and chromosome stability. In addition, the culture conditions with autologous serum coating and autologous plasma supplement enhanced cell growth and colony forming. This cell population contained Muse cells at rate of 0.3%. Moreover, UCB-MSCs could induce the tube formation of human umbilical vein endothelial cells and inhibit more than 50% of SK-MEL cell growth. Conclusions UCB-MSCs could be high-yield isolated and expanded under serum- and xeno-free conditions by using the StemMACS™ MSC Expansion Media kit. Autologous serum coating and plasma supplement enhanced cell proliferation. These UCB-MSCs had effected the tube formation process and an anti-cancer impact.

Purpose: to evaluate the effectiveness of platelet-rich plasma lysate (PRP) in the treatment of patients with post-traumatic eyelid scarring by clinical examples. Material and methods. Patients with post-traumatic scarring changes in eyelid tissues causing a damage in the functional and cosmetic state of the auxiliary apparatus of the eye were treated in the Department of Plastic Surgery and Eye Prosthetics at the Helmholtz National Medical Research Center of Eye Diseases. Two of the patients, who had been traumatized shortly before the examination and one patient who had rejected surgery were offered treatment by PRP lysate manufactured at the Sklifosovsky Medical Research Institute of Emergency Medicine. After local infiltration anesthesia, each patient received a single injection of PRP lysate (2 ml) into the scar tissue. The result was evaluated at a follow-up that took place 3 months after the injection. Results. The clinical picture of the three patients showed a pronounced positive dynamic of the functional and cosmetic state of the auxiliary eye apparatus, which made the patients reject subsequent (additional) surgical treatment. Conclusion. An improvement tissue repair and regeneration processes after PRP lysate injection allows us to assess this method as an applicable alternative of reconstructive operations in certain cases.

Purpose: to study the effectiveness of the use of thrombofibrin clot of platelet-rich plasma (PRP) in patients with corneal ulcers. Material and methods. A clinical study, conducted by the Department of Traumatology and Reconstructive Surgery of Helmholtz National Medical Research Center of Eye Diseases, involved 20 patients, aged from 22 to 82, with corneal ulcers of inflammatory and burn genesis more than 100 microns deep. All patients got coated with a thrombofibrin PRP clot from autologous blood. Prior to the study, all patients received standard treatment for 2 weeks to 3 months, including multiple amniotic membrane coating, with no effect. The thrombofibrin clot was produced by the Scientific Department of Biotechnology and Transfusiology of the N.V. Sklifosovsky Research Institute for Emergency Medicine. The ready clot was placed on the surface of the cornea and covered with an amniotic membrane. The membrane was fixed to the episclera along the border of the limb with a circular suture, whereupon autologous serum was injected along the limb in 4 quadrants, to be followed by temporary lateral blepharography. Results. On the 2nd day following the procedure, the patients noted a decrease in lacrimation and pain in the operated eye. As shown by optical coherence tomography, the average depth of the corneal ulcer at the beginning of the study in all patients was 129 ± 28.5 microns. On the 5th day, the depth lowered to an average of 71 ± 32.6 microns, and on the 10th day, to 23.3 ± 15.1 microns. In 7 patients (35%), complete healing of the defect was observed on the 15th day, while in 9 patients (45%) it was stated between the 16th and the 20th day. Thus, the average time of healing of the ulcer with complete epithelization occurred was 15 days. In four patients with the consequences of severe burns (20%), the ulcer did not heal due to extensive damage to the limbal zone. Conclusion. The use of a thrombofibrin PRP clot in combination with amniotic membrane transplantation allows achieving a stable and fairly rapid healing of corneal ulcers of various origins. However, this method is ineffective in patients with limbal cell insufficiency, severe burns and extensive damage to the limbal zone. In such cases, it is advisable to use more radical surgical methods, such as buccal or limbal cell transplantation, or allolimbal transplantation.

Purpose: to evaluate the effectiveness of platelet-rich plasma (PRP) lysate in patients with corneal erosion or posttraumatic scarring of eyelid tissues.Material and methods. The study involved 30 patients aged 22 to 82 (51.5 ± 19.1 years): 10 with persistent corneal erosions, who were treated in 2 stages (2 weeks of standard keratoprotective therapy, then treatment supplemented with instillations of PRP lysate) and 20 patients with post-traumatic scarring of eyelid tissues, who were divided into a clinical group and a comparison group. PRP lysate was produced in the cell transplantation and immunotyping laboratory of N.V. Sklifosovsky Research Institute for Emergency Medicine.Results. In group 1, already on the 3rd day of PRP lysate use, a positive dynamic of the cornea was observed: all patients had fewer complaints of pain, photophobia, and lacrimation. Corneal biomicroscopy, performed daily over the entire epithelization period, revealed a decrease in hyperemia of the tarsal and bulbar conjunctiva and corneal edema, which indicated a weakened inflammatory response. On average, the area of the cornea at the start of traditional therapy was 21.6 [19.6; 30.65] mm2. After two weeks of treatment, at the time of adding PRP lysate, the average area of erosion fell to 15.7 [12; 18.9] mm2, after a week of treatment with lysate, it dropped to an average of 2.35 [0.4; 4.3] mm2. On day 14, all patients revealed complete epithelialization of the corneal defect. In patients with post-traumatic eyelid tissue scars, after a 3-month-long use of PRP lysate (study group), an improvement was noted in the cosmetic and functional state of the eyelids, on average by 4 points (Me = 12 [10; 12] points before and 8.5 [8; 9] points after treatment (on the Manchester scar assessment scale), in contrast to the patients who received no anti-scar therapy (comparison group), as the latter showed a deterioration in the condition of eyelid scars by 1–2 points (Me = 11 [10.25; 11.75] points at the beginning and 12 [11; 12] points at the end of the observation period). The acoustic density of scar tissue in the study group approached the normal values, in contrast to the comparison group, in which scar tissue appeared to be hypoechoic.Conclusion. Using PRP lysate aimed at improving the repair and regeneration processes in patients with corneal erosion or post-traumatic scarring of eyelid tissues is promising and requires further clinical study.

Abstract Objective Currently, the replacement of fetal calf serum (FCS) by a more suitable alternative is a sought aim in the field of tissue and cell culture research. Autologous plasma (AP) and especially autologous serum (AS) have been shown to be effective substitutes of FCS in culture media for some of the cell types. Nevertheless, there is no comparative data on the most appropriate supplement for cell media in neutrophil studies, it is now unclear whether AP have a relatively equal, superior or inferior performance to FCS in neutrophil cell culture. In the present study, human blood neutrophils were isolated and cultured in FCS- or AP-supplemented medium. After 12, 36 and 60 h of incubation, cell viability, oxidative burst and CD11b expression were determined by flow cytometry. Results Compared to the culture of neutrophils in FCS 10% medium, the culture of neutrophils in a medium with AP 10% could prolong their life span without affecting their function. The findings introduce AP as a better supplement for human neutrophil cell culture than FCS and propose a simple and economical procedure for neutrophil isolation and culture.

The purpose. Using clinical observation, to study the feasibility of applying a coagulant and to assess its efficacy in the treatment of patients with post-burn erosion of the cornea.Material and methods. The treatment was carried out in the Department of Trauma and Reconstructive Surgery, the Helmholtz Moscow Research Institute of Eye Diseases, Russia. Based on clinical test results, the patient, was diagnosed with post-burn persistent erosion of the cornea with sub-total cornea conjunctivization and: limbal stem cell deficiency (LSCD) in the right eye. The keratoprotective therapy conducted for several months turned ineffective. In order to activate the cornea regeneration process, the erosion site was covered with autologous thrombofibrin clot that had been obtained from the stabilized blood. Following a two-stage centrifugation of patient's stabilized blood, the plasma with the platelets were collected into a round-bottomed test-tube; and the chloride calcium activator was added. The clot was formed in the thermostat at a temperature of 37 С. The patient was given a local anesthesia, and the thrombofibrin clot was placed on the cornea surface and covered with an amniotic membrane. The membrane was fixed with a circular stitch along the limbus of the cornea.Result. The patient was followed-up and showed positive changes over time in the form of a diminished erosion area at day 5 and a complete corneal epithelialization at day 14.Summary. Our methodaimed at enhancing the reparative and regenerative processes in the cornea, reducing swelling, accelerating epithelialization, expanding transparency, and improving the optic characteristics thanks to less intensive opacity formation showed a high efficacy.

Background There is a time lag between hair follicle harvesting and implantation, during this time hair follicles suffer ischemic injury. We need a holding medium or a solution to minimize or neutralize ischemic injury. Aims and Objective To evaluate plasma as a graft holding solution in terms of its efficacy in hair growth and hair graft survival. Method and Material A split scalp study was performed. The left side was designated as the control area (Group A) where grafts implanted were kept in Ringer’s lactate, and the right side behaved as the test area (Group B) and received grafts preserved in autologous plasma. The p-value was calculated. Observations MTT staining for grafts stored in Ringer’s lactate at 12 and 72 hours showed poor hair follicle cells’ survival while grafts kept in plasma showed viable cells even after 72 hours. The hair count and density in plasma group were significantly higher than those in the Ringer’s lactate group. There was an improvement in hair thickness in both groups from 6 months to 12 months. Conclusion Autologous plasma is an easily available graft holding solution. Platelets along with the plasma provide multiple growth factors promoting epithelialization, neovascularization, and action on hair follicle stem cells to improve growth. The fibrin coating around the graft makes it sticky and prevents dehydration. The split scalp controlled study certainly shows the advantages of using plasma over other extra cellular graft holding solutions.

The study was undertaken to evaluate the therapeutic efficacy of Ozone and Autologous plasma in 40 infectious repeat breeder cows. The animals were divided in 2 different groups viz. Group-I 20 and Group-II 20 treated with Ozone @55µg/ml in 60ml distilled water and Autologous plasma @ 30ml in intrauterine route, respectively. The diagnosis was confirmed by estimation of pH, PMN cell count, White Side Test and Spinnbarkeit test, which indicated 93.00% cows having alkaline pH, PMN cell count >5% and all cases positive for White Side Test. It was observed that pH of CVM in infectious cows before treatment was 8.00±0.07 and 8.13±0.08 which was reduced after treatment 7.32±0.07 and 7.49±0.08, while PMN cells before treatment revealed as 9.35±0.37 and 9.80±0.44 which was changed to 4.90±0.40 and 4.80±0.65 after treatment and Spinnbarkeit value before treatment was 9.00±0.32 and 9.15±0.27 changed to 15.15±0.59 and 14.95±0.61 after treatment under Groups-I and II, respectively. Recovery rate after treatment were found as 75.00 and 65.00 per cent, respectively. The conception rate was found as 68.42 and 55.00 per cent in cows in Group-I and II, respectively. On conclusion, cows treated with Ozone showed higher recovery rate. [ABSTRACT FROM AUTHOR]

Stress urinary incontinence (SUI) is a common disease. It is 2 times more common among women than in men. The causes of SUI are the insufficiency of the closing function of the sphincter of the bladder and/or hypermobility of the urethra. For this reason, methods aimed at improving the closing function of the urethra, i.e., the use of volume-forming agents are justified for the treatment of this disease. Side effects and time-limited relief of symptoms of urinary incontinence after the application of volumeforming agents, or at the other hand complications after surgery lead to the search for alternative treatments that can restore the natural physiological mechanism of urinary retention. This study demonstrates that administration of platelet-rich autologous plasma in combination with hyaluronic acid in the periurethral region is a safe and effective method of treatment of SUI in women.

BACKGROUND: Diabetes mellitus is frequently associated with microcirculation pathology and hemorheological disorders. METHODS: 24 patients with diabetic foot and 22 healthy subjects were recruited. RBC aggregation, disaggregation and morphology of aggregates were determined in autologous plasma and serum. RESULTS: The RBC aggregation in patients with diabetic foot increased in autologous plasma and serum. Increased red blood cell aggregate strength in these patients was observed only in autologous plasma. Microscopic images of RBC aggregates of patients with diabetic foot show the formation of pathologic globular structures of aggregates in autologous plasma and serum. CONCLUSION: The RBC aggregation in autologous plasma and autologous serum in patients with diabetic foot is significantly higher than in healthy subjects. Increase in strength of RBC aggregates in diabetic foot patients was observed only in autologous plasma. The microscopic images of RBC aggregates in patients with diabetic foot indicate the formation of globular (pathologic) structures of aggregates in autologous plasma and serum. The differences in the morphology of RBC aggregates in autologous plasma and serum between healthy subjects and diabetic foot patients, obtained by microscopic image analysis with high magnification light microscope, can be used as an additional diagnostic tool in medical practice.

Background: Injection of autologous blood can stimulate a healing response in chronic tendon disorders. Objective: To comparing the effectiveness of intralesional autologous plasma with intralesional corticosteroid injection for treatment of plantar fasciitis. Patients and Methods: Sixty-one adult patients presented to the orthopedic clinic in Erbil Teaching Hospital from 1st of January, 2015 to 31st of December, 2015, with chronic proximal plantar fasciitis were included in this study. They were allocated into two groups, group A, the autologous plasma group (30 patient), and group B, the corticosteroid group (31 patients). Pain severity was assessed depending on visual analogue scale scores before treatment and at 2 weeks, 1 month, and 3 months after treatment. Results: At first week and first month after treatment the pain reduction was significantly higher among corticosteroid group (P = 0.012 and 0.010, respectively). While at third month after treatment there was no significant difference in pain reduction (P = 0.11). Reduction in visual analogue scale scores for both groups was significant over time (p < 0.001). However, the corticosteroid group showed an earlier sharp drop and a plateau in average pain levels at the lower end of the scale as early as 2 weeks. Conclusion: Intralesional autologous plasma injection was effective in lowering pain and tenderness, although not as quicker than and as effective as the corticosteroid. [ABSTRACT FROM AUTHOR]

The aim of this study was to isolate mesenchymal stem cells (MSCs) from feline peripheral blood (fPB-MSCs) and to characterise the cells' in vitro properties. The mononuclear cell fractions were isolated from venous blood of cats by density gradient centrifugation and cultured on plastic dishes under various culture conditions to isolate MSCs. When these cells were cultured with 5% autologous plasma (AP) and 10% foetal bovine serum (FBS), adherent spindle shaped fibroblast-like cells (fPB-MSCs) were obtained from 15/22 (68%) cats. These cells were isolated only from medium containing both AP and FBS. The morphology of these MSCs was similar to those isolated from other species and from other feline tissues. fPB-MSCs expanded steadily up to 5–6 passages, but had increased population doubling time during passaging and almost all cells stopped proliferation at passages 7–9. These cells expressed CD44 and CD90, and were mostly negative for major histocompatibility class II and CD4. The cells could be induced to differentiate into adipogenic, osteogenic and chondrogenic cell lineages. These findings indicate that fPB-MSCs can be generated but appear to require specific culture conditions. [ABSTRACT FROM AUTHOR]
