ObjectivesDeep Brain Stimulation (DBS) is an effective, yet underused therapy for people living with Parkinson’s disease (PD) in whom tremor, motor fluctuations and/or dyskinesia are not satisfactorily controlled by oral...

Sacral neuromodulation in pediatric refractory bladder and bowel dysfunction Insights from Canada's first pediatric cohort.

Refractory bladder and bowel dysfunction (BBD) significantly affects the health and quality of life of children and their caregivers, emphasizing the need for effective and minimally invasive treatments. This study aims to present the inaugural Canadian experience using sacral neuromodulation (SNM ) as a therapeutic option for children with refractory BBD. Patients <18 years old with refractory BBD were prospectively followed from 2018 to the present. Preoperative evaluation included spinal MRI and video urodynamics. Two-stage SNM implantation was executed with a minimum two-week stage 1 trial. Functional outcomes and complication rates were measured following validated questionnaires. Six patients completed staged implantation at a median age of 10.8 years (range 8.2-18). The median baseline Dysfunctional Voiding Scoring System (DVSS) score was 12.5 (10-22). At six months of followup, only one patient required adjunct bladder medication. Median DVSS at one-year followup was 5.5 (0-7). Symptomatic resolution was noted in three patients at six months, sustained over one year. Early surgical complications were reported in one (infection) and late complications in three (lead fracture, battery depletion, non-traumatic malfunction), requiring reimplantation at a median of 37.5 (1-49) months. Post-SNM reimplantation, oral medication and rectal therapy decreased, and DVSS scores improved by 30% (0-63.6) at six months. SNM is feasible and offers promising results for refractory pediatric BBD in Canada. The significant improvement of symptoms highlights the treatment's potential, which must be balanced against the high need for revision detected at three years, possibly related to patients' growth and high activity level.

Non-invasive laser therapy effect on lipid profile and renal function in metabolic syndrome: randomized control trial

INTRODUCTION. Metabolic syndrome (MetS) represents an assortment of interconnected metabolic risk factors, particularly central obesity, dyslipidemia, and hyperglycemia. These variables have a detrimental impact on renal function and contribute to increased mortality. This timeline necessitates a prompt approach that enables the deployment of safe and non-intrusive therapeutic equipment in conjunction with therapy for MetS patients. Accordingly, we aim to investigate whether using a low-level laser (LLL) watch device as a non-invasive instrument enhances multiple metabolic parameters, so it may be a practical therapeutic approach for managing metabolic disorders. AIM. To investigate the effect of non-invasive laser therapy on parameters of lipid profile and renal function in patients with metabolic syndrome. MATERIALS AND METHODS. This study enrolled 40 MetS patients of both genders aged 45–65 years. The study group received a 12-week treatment consisting of oral hypoglycemic medication and LLL therapy (LLLT), which involved three weekly sessions performed in the morning, targeting the wrist area using a continual output diode laser (skin contact mode, maximum power: 0.005 W, beam spot area: 0.03 cm2, energy density: 288 J/cm3, and radiation time: 1800 s). The control group only received hypoglycemia medications. Laboratory lipid profile and renal function measurements were conducted prior to and following the trial. RESULTS. Following a 12-week laser watch therapy, the results revealed a significant decline in total cholesterol (TC), triglycerides (TG), and low-density lipoprotein (LDL) levels and an increase in high-density lipoprotein (HDL) levels, which was slightly improved in the control (p 0.00). Moreover, glomerular filtration rate (GFR) and creatinine levels were significantly improved, while the control group did not experience any significant improvement (p 0.5). DISCUSSION. Combining non-invasive laser therapy with hypoglycemic medications significantly improved the lipid profile in patients with MetS; however, kidney function, like GFR and creatinine levels, was enhanced. Furthermore, lower TC and TG levels might be due to the reduction of glycation and promoted LDL receptors which increased LDL catabolism. CONCLUSION. Non-invasive laser therapy enhances lipid profile and renal function in MetS patients. Furthermore, the control group had a minimal effect on the lipid profile and no effect on renal function.

Use and Intensification of Oral Guideline-Directed Medical Therapy in Hospitalized Patients With Heart Failure and Reduced Ejection Fraction

Adults with heart failure with reduced ejection fraction are at increased risk for morbidity and mortality, especially if hospitalized for acute decompensation. Evidence-based medication therapies are frequently underused or inappropriately prescribed, which further exacerbates poor outcomes for these patients. Provider inertia has been identified as a leading cause of poor medication utilization. Nurse practitioners in an acute care setting are uniquely positioned to improve outcomes by prescribing and intensifying oral therapies during acute decompensated heart failure. This article describes the current evidence-related core guideline-directed medical therapy along with strategies for intensification during hospitalization.

Experience from a single-center study on multimodal medication therapy for patients with complex regional pain syndrome.

Despite the application of various therapeutic methods, pain caused by complex regional pain syndrome (CRPS) is not sufficiently managed and often progresses to a chronic stage. For the systematic and effective treatment of CRPS, we developed an algorithm for multimodal medication therapy based on the established pathophysiology of CRPS to control CRPS-related pain. In this study, we present the outcomes of our novel algorithm for multimodal medication therapy for patients with CRPS, consisting of three major components: multimodal oral medication, intravenous ketamine, and intravenous lidocaine therapy. We retrospectively investigated patients with CRPS who received multimodal therapy. Pain severity scores were evaluated using a numerical rating scale at four time points (P1, pain at initial consultation; P2, pain after oral medication; P3, pain after ketamine treatment; and P4, pain after lidocaine treatment). The effect of the multimodal medication therapy algorithm on pain management was evaluated at each time point. In patients with CRPS, multimodal oral medication, intravenous ketamine, and intravenous lidocaine therapies led to significantly improved pain control (p< 0.05). Additionally, the combination of these three therapies (through the multimodal medication therapy algorithm) resulted in significant pain relief in patients with CRPS (p< 0.05). Our multimodal medication therapy algorithm effectively controlled pain in patients with CRPS. However, further prospective studies with large sample sizes and randomized controlled trials are needed for more accurate generalization.

Acute heart failure (AHF)

Acute heart failure (AHF) is a frequent cause for emergency consultations, leads to long hospital stays and is characterized by high mortality and rehospitalization rates, with the first months after hospitalization having the highest risk («vulnerable phase»). The clinical presentation is usually characterized by fluid accumulation. Over the last three decades, few advances have been achieved in the treatment of AHF, as most studies with diuretics or vasodilators failed to show positive effects in terms of mortality and rehospitalization rates. In this context, the treatment of AHF must have an integrative approach, consisting of rapid correction of systemic congestion on the one hand, and specific therapies for the precipitating factors, the underlying cardiac pathology, and non-cardiac comorbidities on the other. Recently, it has been shown that a rapid and intensive up-titration of oral heart failure medical therapy during and immediately after hospitalization can improve the prognosis during the vulnerable phase after AHF. In this article, the principles of optimization and personalization of diuretic therapy and oral heart failure medication during hospitalization and the early outpatient phase after AHF are discussed.

Comparison of Acebrophylline vs Theophylline on Chronic Obstructive Pulmonary Disease

Over the past few decades, there has been a positive increase in the use of pharmaceutical treatment for chronic obstructive pulmonary disease (COPD). Methylamines are often used in COPD patients. Theophylline is a well-known bronchodilator and anti-inflammatory medication, and acebrophylline is a relatively recent addition to contemporary respiratory care. Both are used as adjunctive therapy for patients with stable COPD who are receiving long-acting muscarinic antagonists (LAMAs). One of the world's most pressing public health issues at the moment is chronic obstructive pulmonary disease (COPD). Oral medication therapy is utilised as a second- or third-line maintenance treatment for COPD, while inhaled treatments constitute the first-line maintenance treatment. In comparison to inhaled therapy, oral medications exhibit modest bronchodilator and anti-inflammatory properties, albeit at a lesser concentration. A number of benefits of oral medication therapy include its rapid availability, cloudiest pharmacologic methods of action, convenience of administration, lack of complications with correct inhalational drug deposition in lung airways, and cost-effectiveness.

The Impact of an Overactive Bladder Care Pathway on Longitudinal Patient Management.

Implementation of an overactive bladder (OAB) care pathway may affect treatment patterns and progression. This study aimed to assess the effect of OAB care pathway implementation on treatment patterns for women with OAB. This retrospective cohort study evaluated women with OAB, before (January 1, 2015-December 31, 2017) and after (January 1, 2019-December 31, 2021) care pathway initiation. Care pathway use included standardized counseling, early introduction of therapy, and close follow-up. Primary outcomes included OAB medication use, follow-up visits, third-line therapy, and time to third-line therapy. A total of 1,349 women were included: 1,194 before care pathway implementation and 155 after. Patients after implementation were more likely to have diabetes mellitus (P = 0.04) and less likely to smoke (P = 0.01). Those managed via a care pathway were more likely to use any medication or third-line therapy within 1 year after consultation (61.3% vs 25.0%; P < 0.001). This included higher proportions receiving a medication (50.3% [95% confidence interval (CI), 41.8%-57.6%] vs 23.3% [95% CI, 20.9%-25.7%]; P < 0.001) and progressing to third-line therapy (22.6% [95% CI, 15.7%-28.9%] vs 2.9% [95% CI, 2%-3.9%]; P < 0.001). Among those who underwent third-line treatment, care pathway use was associated with shorter time to third-line therapy (median, 10 days [interquartile range, 1-56 days] vs 29 days [interquartile range, 7-191 days]; P = 0.013). Those managed via a care pathway were less likely to have additional clinic visits for OAB within 1 year after initial consultation (12.3% vs 23.9%; P < 0.001). Use of an OAB care pathway was associated with higher rates of oral medication and third-line therapy yet decreased follow-up office visits. Use of an OAB care pathway may promote consistent and efficient care for women with OAB.

Association between adherence with oral anticancer medications and short-term health care resource utilization: A 2010-2018 claims-based analysis.

There is limited evidence on the effect of adherence to oral anticancer medications on health care resource utilization (HRU) among patients with cancer. To determine the association between adherence to oral anticancer medication and subsequent HRU. A retrospective cohort study was conducted using Optum Clinformatics® Data Mart commercial claims database. Patients who initiated an oral anticancer medication between 2010 and 2017 were included. Proportion of days covered was used to calculate medication adherence in the first 6 months after oral anticancer medication initiation. All-cause HRU in the following 6 months was assessed. Multivariable negative binomial regressions were used to determine the association between oral anticancer medication adherence and HRU, after controlling for confounders. Of 37,938 patients, 51.9% were adherent to oral anticancer medications. Adherence with oral anticancer medication was significantly associated with more frequent physician office and outpatient visits for several cancer types with the strongest association among those with liver cancer (adjusted incidence rate ratio [aIRR] = 1.34; 95% CI = 1.18-1.52 and aIRR = 1.32; 95% CI = 1.13-1.55, respectively). Oral anticancer medication adherence was associated with more emergency department visits only among patients with lung cancer (aIRR = 1.22; 95% CI = 1.01-1.48). Oral anticancer medication adherence was significantly associated with a higher rate of inpatient hospitalizations and longer stays among patients with liver cancer (aIRRs were 1.45 [95% CI = 1.02-2.05] and 2.15 [95% CI = 1.21-3.81], respectively), whereas hospitalizations were fewer and length of stay was shorter among patients with colorectal cancer who were adherent with oral anticancer medication (aIRRs were 0.77 [95% CI = 0.68-0.86] and 0.77 [95% CI = -0.66 to 0.90], respectively). Other measures did not reveal statistically significant differences in HRU among adherent and nonadherent patients for the cancer types included in the study. HRU following the initial phase of oral anticancer medication therapy was generally similar among adherent and nonadherent patients. We observed a slightly higher rate of office and outpatient visits among adherent patients, which may reflect ongoing monitoring among patients continuing oral anticancer medication. Further studies are needed to determine how oral anticancer medication adherence may affect HRU over a longer time period.

Osmotic Demyelination Syndrome after Correction of Hyponatremia

Osmotic demyelination syndrome is a rare neurological disease resulting in cerebral apoptosis and loss of myelin due to osmotic stress. Based on anatomical localization and pathological attributes, ODS can be categorized as Central Pontine Myelinolysis (CPM) and Extrapontine Myelinolysis (EPM). It has a biphasic course, with first phase reflecting electrolyte imbalance and the second with pontine dysfunction, impaired vigilance and movement disorders. In an autopsy-based study, a prevalence rate of 0.25–0.5% was seen in the general population and 10% in patients undergoing liver transplantation. Being a rare disease with variable, but preventable outcome, the present case was managed with Ayurvedic oral medication and Panchakarma therapy with an aim to improve the quality of life. In Ayurvedic perspective, Vata kshaya lakshanas occur during the phase of hyponatremia and further correction of this leads to disruption of osmolality (Kapha pitta accumulation) resulting in Avarana of Vata. This may be the reason for demyelination and localisation of Vata in Sira and Snayu leading to Sira snayu shoshana on both halves of the body resulting in Sarvangaroga (full body afflicted with Vata). Thus Avaranahara, Srotosodhana and Vatanulomana principles were adopted. An improvement in Barthel index and modified rankin scale were observed after a course of treatment for 30 days.

Therapies for Parkinson's disease and the gut microbiome: evidence for bidirectional connection.

The gut brain axis (GBA), a bidirectional communication pathway has often been linked to health and disease, and gut microbiota (GM), a key component of this pathway shown to be altered in Parkinson's disease (PD), are suggested to contribute to the pathogenesis of PD. There are few studies that report the impact of oral medication therapy on GM, however, there are even fewer studies that discuss the impact of other treatments such as device assisted therapies (DAT) including deep brain stimulation (DBS), levodopa-carbidopa intestinal gel infusion (LCIG) and photobiomodulation (PBM) and how these might impact GM. Here, we review the literature and summarize findings of the potential contributions of GM to the heterogenous clinical response to pharmaceutical therapies among individuals with PD. We also discuss the potential interactions between the GM and DATs such as DBS and LCIG and present evidence for alterations in GM in response to DATs. Given the complexity and highly individual nature of the GM of patients with PD and the potential influence that other external factors such as diet, lifestyle, medications, stage of the disease and other comorbidities, further investigations into the response of GM to therapies are worthy of future study in prospective, controlled trials as well as medication naïve individuals. Such detailed studies will help us further comprehend the relationship between GM in PD patients, and will help investigate the potential of targeting GM associated changes as a treatment avenue for PD.

Worsening of chronic heart failure: definition, epidemiology, management and prevention. A clinical consensus statement by the Heart Failure Association of the European Society of Cardiology.

Episodes of worsening symptoms and signs characterize the clinical course of patients with chronic heart failure (HF). These events are associated with poorer quality of life, increased risks of hospitalization and death and are a major burden on healthcare resources. They usually require diuretic therapy, either administered intravenously or by escalation of oral doses or with combinations of different diuretic classes. Additional treatments may also have a major role, including initiation of guideline-recommended medical therapy (GRMT). Hospital admission is often necessary but treatment in the emergency service or in outpatient clinics or by primary care physicians has become increasingly used. Prevention of first and recurring episodes of worsening HF is an essential component of HF treatment and this may be achieved through early and rapid administration of GRMT. The aim of the present clinical consensus statement by the Heart Failure Association of the European Society of Cardiology is to provide an update on the definition, clinical characteristics, management and prevention of worsening HF in clinical practice.

Systematic Review of Nutrition Interventions to Improve Short Term Outcomes in Head and Neck Cancer Patients.

Head and neck cancer (HNC) is associated with high rates of malnutrition. We conducted a systematic review and descriptive analysis to determine the effects of nutrition interventions on the nutrition status, quality of life (QOL), and treatment tolerance of HNC patients. PubMed, Web of Science, and Embase were searched to include all potentially relevant studies published between 2006-2022. Meta-analysis was not conducted due to heterogeneity of study designs and outcomes reported. Studies were categorized as nutrition interventions: (1) with oral nutrition supplements (ONS) and medical nutrition therapy (MNT) delivered by an RD; (2) with enteral nutrition (EN) support and MNT delivered by an RD; (3) with motivational interviewing and no ONS or EN; and (4) with ONS and no RD. Seven articles met inclusion criteria. Studies measured outcomes from immediately following treatment to 12 months post-treatment. Interventions resulted in benefits to lean mass/weight maintenance (three studies), QOL (two studies), nutrient intake adequacy (one study) and treatment tolerance (two studies). Nutrition counseling by a registered dietitian leads to improved nutrition status and QOL. Further research is needed to determine best practices related to timing of initiation, duration of nutrition intervention, as well as frequency of dietitian follow-up.

Labium superius oris mucormycosis: an enigma

Mucormycosis is an aggressive opportunistic fungal infection affecting immunocompromised patients. It has six manifestations: rhinocerebral, pulmonary, cutaneous, gastrointestinal, disseminated and localized infection. However, isolated mucormycosis of upper lip (labium superius oris) without any bony invasion has not been reported in literature to the best of our knowledge. Hence this poses a diagnostic challenge. A 50-year-old male came with left sided nasal pain and left sided nasal obstruction associated with very mild uniform swelling of upper lip of 24 months duration. He underwent FESS in a local hospital and was misdiagnosed as granulomatous origin probably Tuberculosis. Even on ATT the symptoms didn’t subside and hence presented to our hospital. On incisional biopsy deep fungal infection probably mucor was reported and he was put on tab Posaconazole 300 mg OD. On recurrent upper lip swelling, excision biopsy was done. HPE was reported as fibrocollagenous stroma interspersed by multiple non-caseating epitheloid granulomas with plenty of foreign body type of giant cells. PAS showed broad aseptate acute angled hyphal forms suggestive of mucor. The follow up clinical presentation of the patient was very satisfactory with complete regression of upper lip swelling and no damage to surrounding structures. The case report highlights the existence of localized form of mucormycosis without bony necrosis in immunocompetent patients which require minimal surgical intervention along with oral medical therapy rather than extensive debridement.

This quality improvement study evaluates access to oral COVID-19 therapeutics within communities in the 48 contiguous states and the District of Columbia.

Protein cohabitation: long-term immunoglobulin G storage at room temperature.

Long-term functional storage of therapeutic proteins at room temperature has been an eternal challenge. Inspired by the cellular cooperativity of proteins, we have taken a step forward to address this challenge by cohabitating Immunoglobulin G (IgG1) with a food protein gelatin in the solid-state at room temperature. Interestingly, IgG1 remained functionally active for a record 14 months revealed from the western-blot assay. Further quantification by HP-LC analysis showed 100% structural integrity of IgG1 with no degradation in the gelatin matrix during this period. The developed formulation has a direct application in oral medical nutrition therapy to cure gastrointestinal microbial infections. Also the strategy provides a robust energy economic alternative to the protein engineering methods for long-term functional storage of therapeutic proteins at room temperature.

Effect of Ayurvedic oral medication and Panchakarma therapy in Gridhrasi (Sciatica) - A Case Report

Gridhrasi is one among eighty diseases of Vata. Here Gridhra refers to vulture and typical walking style is acquired in Gridhrasi. Here typical gait refers to slight tilt towards the affected part of body. The clinical features of Gridhrasi is low back pain which is radiating to the hip, the back of thighs and down to leg. It can be correlated to Sciatica. Sciatica is the painful condition in which pain starts in the lumbar area and radiates along the course of the sciatic nerve. For present study, we have reported 38 years old male patient having symptoms since 15 days. Before treatment, patient was unable to walk even 4 to 5 steps, Visual Analogue Scale score was 10, range of motion was restricted and painful, his SLR test was positive at 150 of right side and 30°of left side. The aim of study is to evaluate the effect of Ayurvedic treatment protocol in Gridhrasi. Shamana (pacification), Shodhana (purification) was the main treatment modalities planned in this patient. Ksheera Basti was main line of treatment planned. After 52 days of treatment he was able to walk up to 500 meters without any difficulty, Visual Analogue Scale score changed to 2, was able to move the leg with minimal pain and SLR test was changed to 60° on both sides. Patient got 80% relief from pain. This article highlights a case study treated with simple Ayurvedic formulations and Ksheera Basti which is helpful in reducing the symptoms and stopping the recurrence of the disease. The results with rationality have been depicted in this article.

Benefits and safety of Oxymetazoline cream 1% on rosacea-associated erythema: A systematic review and analysis of clinical evidence.

Facial persistent erythema is recognized as difficult feature to treat in rosacea. Topical Oxymetazoline cream 1% has been used to treat persistent facial erythema in rosacea patients for some years. To quantitatively synthesize the benefits and harms of Oxymetazoline cream 1% in real-world clinical management of treatment response and adverse events. The clinical researches before June 1, 2022 published on online databases including PubMed, Web of Science, Embase and Cochrane Library were meta-analyzed. A total of 2298 participants were included, and the improvement rate of two-grade Clinician Erythema Assessment score (CEA) and Subject Self-Assessment for rosacea facial redness score (SSA) in Oxymetazoline group was 38% (95%CI 28-48) and 25% (95%CI 22-27), respectively, at the 4th week of the dosing. The comprehensive rate of treatment-related TEAEs in Oxymetazoline group was 7% (95%CI 5-8). The rate of stinging/burning was 15% (95%CI 10-19), pruritus was 15% (95%CI 9-22), dryness was 23% (95%CI 18-28), and scaling was 17% (95%CI 12-22) in analysis of dermal tolerability. And topical Oxymetazoline cream 1.0% presented a very low rebound rate of erythema (1%, 95%CI 0-2). These real-world data on Oxymetazoline cream 1% in rosacea-associated erythema may help making clinic decision and informing treatment expectations, and more clinic trials on longer-term dosing or the combination treatment with oral medication and energy-based therapy are worth exploring.

Advances in traditional Chinese medicine as adjuvant therapy for diabetic foot.

Diabetes mellitus (DM) is a complex disease that often causes multiple systemic complications that have become a major international public health problem. Diabetic foot (DF) is one of the severe and frequent chronic complications of DM due to vascular lesions and neuropathy. DF ulcers (DFU) affect approximately 15% of people with DM and are the leading cause of death and disability. The prevalence and recurrence of DF are worrisome, and morbidity and mortality are also on the rise, which poses a substantial socioeconomic burden. Treating DF is difficult for clinicians and requires multidisciplinary cooperation, combining local and systemic therapy to reduce amputation and case-fatality rates. Traditional Chinese Medicine (TCM) has received extensive attention due to noticeable therapeutic effects and few adverse reactions. In recent years, research on DF treatment by TCM has been increasing, and further progress has been made. TCM includes oral medication, injectable preparations, and adjuvant therapy. This article reviews the relevant research on TCM-related adjuvant therapy for DF. We describe current progress in TCM in terms of external application, acupuncture, massage, acupoint injection, foot bath, fumigation, and moxibustion, as well as the mechanisms involved.

Role and Effectiveness of Intra-articular Injection of Hyaluronic Acid in the Treatment of Knee Osteoarthritis: A Systematic Review.

Osteoarthritis (OA) is a degenerative joint disease that causes persistent joint pain and stiffness of mainly the large peripheral weight-bearing joints. It is a leading cause of functional disability and poor quality of life. Various modalities of therapy are recommended by different research organizations at different stages of OA including non-pharmacological, pharmacological, and surgical interventions. Intra-articular injections of hyaluronic acid (HA) is widely used for over three decades in the treatment of OA. However controversies exist regarding its safety and efficacy, the number of injections and courses, type of preparation, duration of its effects, and combining it with other drugs or molecules. This study aimed to review the most recent data available in the published literature to address these.Electronic databases like Medline, Embase, ProQuest, and Google Scholar were searched for articles using keywords, intraarticular injections, hyaluronic acid, and osteoarthritis knee. The review was carried out as per PRISMA guidelines.Thirty-eight randomized control trials (RCTs) investigating the efficacy and safety of intra-articular injection of HA were included in the systematic review. Out of the 38 studies, 22 (57.9%) were double-blind, eight (21%) single-blind, three (7.9%) non-blind, four (10%) with simple randomization, and one (2.7%) was open-labeled. Total 5,025 patients were included in these studies. The mean age of the patients was 60.28 years and the osteoarthritis grade of the knee joint was 1 to 3. HA was studied as a test preparation in 19 (50%) while in another 19 (50%) it was studied as a control. In 24 (63.2%) studies, HA was used as high molecular weight preparation in eight (21%) as low molecular weight preparation while in six studies the information was not available. HA was used as a standalone preparation in 31 studies, in two studies it was injected with platelet-rich plasma (PRP) and with either low-level laser therapy (LLLT), triamcinolone (TA), betamethasone (CS), poly deoxyribonucleotide (PDRN) or dexamethasone (DX) in one study each. In the majority of the studies, HA was given as a single injection (52.6% studies) or weekly three injections (28.9% studies). In 13.2 %, it was given as weekly 5 injections and in 5.3% as weekly two injections.IA-HA injections have a limited role in the treatment of knee osteoarthritis in those patients who do not have sufficient pain relief with topical or oral medication and physical therapy. It is safe and effective except for minor side effects such as local pain and swelling lasting for a few days. Severe allergic reactions are extremely rare. They provide adequate pain relief and functional improvement for up to six months irrespective of a number of injections and type of preparations used. The combination formulations with corticosteroids or PRP or MSCs show better results than HA alone. Combining HA with newer molecules such as peptides or diclofenac for sustained and disease-modifying effects requires more studies in the future.
