BACKGROUND
Several studies have reported the association between osteoporosis and major depressive disorder (MDD) as well as the use of antidepressants. However, it remains to be elucidated whether these associations are related to exposure to antidepressants, a consequence of a disease process, or a combination of both.
METHODS
This study investigates the independent effect of the antidepressant duloxetine hydrochloride (DH) on ovariectomy-induced bone loss in mice. One week after ovariectomy, the treated mice received DH. To explore the mechanism underlying the rescue of bone loss, bone marrow cells were isolated from mouse femurs and tibias, and macrophages extracted from them were induced to become osteoclasts in vitro while being treated with DH. Subsequently, the osteoclasts underwent Bulk RNA-Seq to reveal the involved signaling pathways. The results of the bioinformatic analysis were then validated through in vitro experiments.
RESULTS
The in vivo experiments demonstrated that DH treatment compromised ovariectomy-induced bone loss after 7 weeks. The in vitro experiments suggested that DH treatment attenuated osteoclast differentiation via the MAPKs/NFATc1 signaling pathway.
CONCLUSION
The findings from this study suggest that DH, instead of causing bone mass loss, may assist in alleviating postmenopausal osteoporosis. These results can serve as a reference for the clinical treatment of patients with perimenopausal or postmenopausal depression using antidepressants.

Meta-Analysis
INTRODUCTION
The optimal dose of duloxetine in the management of fibromyalgia remains still controversial. Therefore, a systematic review and meta-analysis to investigate efficacy and safety of duloxetine was conducted. The outcomes of interests were to assess changes in Fibromyalgia Impact Questionnaire (FIQ), Brief Pain Inventory (BPI), and Clinical Global Impression (CGI). The rate of of adverse events and those leading to therapy discontinuation were also investigated.
MATERIAL AND METHODS
This study followed the 2020 PRISMA guidelines. The literature search started in December 2022 accessing PubMed, Google scholar, Embase, and Scopus databases. All the RCTs investigating the efficacy and safety of daily administration of duloxetine for fibromyalgia were accessed. Studies reporting quantitative data under the outcomes of interest, and including a minimum of 10 patients who completed a minimum of 4 weeks follow-up, were included. Studies on combined pharmacological and non-pharmacological managements for fibromyalgia were not considered.
RESULTS
Data from 3432 patients (11 RCTs) were included. The mean age of the patients was 46.4 ± 10.7 years old, and the mean BMI 25.3 ± 3.2 kg/m. 90% (3089 of 3432 patients) were women. The 60 mg/daily cohort reported the higher FIQ, followed by the 30, 30-60, 120 mg/daily, and placebo groups, while the 60-120 mg /daily group performed the worst results. Concerning the CGI severity scale, placebo resulted in the lowest improvement, and no differences were found in the other groups. Concerning the BPI interference and severity pain scores, the 30-60 mg/daily group reported the worst result, along with the placebo group. The rate of adverse events leading to study discontinuation were lower in the 60-120 group, followed by the 30-60 and 30 mag/daily groups. Duloxetine was superior in all the comparisons to placebo, irrespective of the doses, in all endpoints analysed.
CONCLUSIONS
Duloxetine could help in improving symptoms of fibromyalgia. The dose of duloxetine should be customised according to individual patients. Irrespective of the doses, duloxetine was more effective than placebo in the management of fibromyalgia. The dose of duloxetine must be customised according to individual patients.

Fibromyalgia is a chronic, centralized pain syndrome characterized by disordered processing of painful stimuli. Fibromyalgia is diagnosed more frequently in women and occurs globally, affecting 2% of people in the United States. Patients with fibromyalgia have diffuse chronic pain, poor sleep, fatigue, cognitive dysfunction, and mood disturbances. Comorbid conditions, such as functional somatic syndromes, psychiatric diagnoses, and rheumatologic conditions may be present. The Fibromyalgia Rapid Screening Tool is a helpful screening method for patients with diffuse chronic pain. The American College of Rheumatology criteria or the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks-American Pain Society Pain Taxonomy diagnostic criteria can diagnose fibromyalgia. Establishing the diagnosis and providing education can reassure patients and decrease unnecessary testing. A multidisciplinary approach that incorporates nonpharmacologic therapies and medications to address problematic symptoms is most effective. Patient education, exercise, and cognitive behavior therapy can improve pain and function. Duloxetine, milnacipran, pregabalin, and amitriptyline are potentially effective medications for fibromyalgia. Nonsteroidal anti-inflammatory drugs and opioids have not demonstrated benefits for fibromyalgia and have significant limitations.

Review
Diabetic neuropathy is a neurodegenerative disorder that may alter both the somatic and autonomic peripheral nervous systems in the context of diabetes mellitus (DM). It is a prevalent and burdensome chronic complication of DM, that requires timely management. Optimized glycemic control (mainly for type 1 DM), multifactorial intervention (mainly for type 2 DM), with lifestyle intervention/physical exercise, and weight loss represent the basis of management for diabetic distal symmetrical polyneuropathy, and should be implemented early in the disease course. Despite better understanding of the pathogenetic mechanisms of diabetic peripheral neuropathy, there is still a stringent need for more pathogenetic-based agents that would significantly modify the natural history of the disease. The paper reviews the available drugs and current recommendations for the management of distal symmetrical polyneuropathy, including pain management, and for diabetic autonomic neuropathy. Evaluation of drug combinations that would perhaps be more efficient in slowing the progression of the disease or even reversing it, and that would provide a better pain management is still needed.

Meta-Analysis Review
Treatment recommendations for fibromyalgia (FM) include a range of predominantly pharmacological treatment options designed to ensure the maintenance of symptoms and improvement in the quality of life of these patients. Our aim is to identify and compare the efficacy of amitriptyline (AMT), duloxetine (DLX), and pregabalin (PGB) for reducing pain intensity by 30% (R30%) and 50% (R50%) in adult patients with fibromyalgia. The review was conducted in the Medline/PubMed, Cochrane Library, and Embase databases up to February 2022. This study included systematic reviews (SR) of randomized clinical trials (RCTs) targeting adult patients over 18 years of age diagnosed with fibromyalgia according to the criteria of scientific societies, which include the basic clinical diagnosis characterized by the presence of pressure sensitivity in at least 11 of the 18 tender points, in addition to the presence of widespread musculoskeletal pain for a period longer than 3 months and a general assessment of the patient's health status. Pregnant women and children or adolescents were excluded. The Rob 2.0 tool from the Cochrane Collaboration was used to assess the risk of bias in RCTs. The quality of evidence of the reviews included was assessed according to the Grading of Recommendations Assessment, Development and Evaluation-GRADE. A meta-analysis for the evidence network was performed using the Bayesian approach, which allows simultaneous comparison of all treatment options (medication and dose). The different treatments were ranked according to the response rate according to the surface under the curve (SUCRA), which was expressed as a percentage. The results were presented in tables and figures. The protocol with the detailed methods was registered in PROSPERO (CRD42021229264). Eight systematic reviews were identified, and, from these, 15 clinical trials comparing AMT (n = 273), DLX (n = 2595), and PGB (n = 3,506) against placebo were selected. For the outcome R30%, PGB 450 mg was superior to DLX 30 mg and PGB 150 mg, while DLX 20 mg and 30 mg were not superior to placebo. For the outcome R50%, AMT 25 mg was superior to all other alternatives evaluated. The calculation of the SUCRA indicated that PGB 450 mg was the best performance option for R30% and AMT 25 mg for R50%. PGB 150 mg was the drug with the worst performance in the two outcomes evaluated. The drugs evaluated showed benefits for pain reduction in patients with fibromyalgia. In the absence of direct comparison studies, indirect comparison meta-analyses are an important resource for assisting in clinical decision-making. Our data only provide an indicator of the effectiveness of the three drugs evaluated, but as with other health conditions, tolerability and safety are important for the decision-making process and clinical management. In this regard, we encourage caution in interpreting our data.

Review
Diabetic peripheral neuropathy (DPN) is one of the most prevalent chronic complications of diabetes. The lifetime prevalence of DPN is thought to be >50%, and 15%-25% of patients with diabetes experience neuropathic pain, referred to as "painful DPN." Appropriate treatment of painful DPN is important because this pain contributes to a poor quality of life by causing sleep disturbance, anxiety, and depression. The basic principle for the management of painful DPN is to control hyperglycemia and other modifiable risk factors, but these may be insufficient for preventing or improving DPN. Because there is no promising diseasemodifying medication for DPN, the pain itself needs to be managed when treating painful DPN. Drugs for neuropathic pain, such as gabapentinoids, serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, alpha-lipoic acid, sodium channel blockers, and topical capsaicin, are used for the management of painful DPN. The U.S. Food and Drug Administration (FDA) has approved pregabalin, duloxetine, tapentadol, and the 8% capsaicin patch as drugs for the treatment of painful DPN. Recently, spinal cord stimulation using electrical stimulation is approved by the FDA for the treatment for painful DPN. This review describes the currently available pharmacological and nonpharmacological treatments for painful DPN.

Comparative Study Randomized Controlled Trial
BACKGROUND
Duloxetine and pregabalin are among the most widely used medications in the treatment of patients with fibromyalgia syndrome (FM).
OBJECTIVES
To add to the very few lines of evidence that exist on the comparative safety and efficacy of these two medications.
METHODS
In this open-label randomized clinical trial, outpatient women, who were diagnosed with FM based on American College of Rheumatology 2010 criteria, and had an age range of 18-65 years old were assigned to either duloxetine 30-60 mg or pregabalin 75-150 mg per day for 4 weeks. Patients were excluded in cases of having used duloxetine, pregabalin, gabapentin, or antidepressants within 12 weeks prior to the study, having had a history of comorbid medical conditions that could provoke chronic pain, or having had comorbid neuropsychiatric disorders, except for major depressive/anxiety disorders. Primary outcomes were between-group differences in mean score changes from baseline to end point for Widespread Pain Index (WPI) and Beck Depression Inventory-II. Secondary outcomes were the same statistical estimates, but for Fibromyalgia Impact Questionnaire-Revised and 12-Item Short Form Survey. Descriptive statistics and independent samples t-test were the main methods of analysis. ( www.irct.ir ; IRCT2016030626935N1).
RESULTS
Among all the scales, only WPI scores improved with a statistically significant difference between the two treatment arms, favoring duloxetine (Mean difference in score change - 2.32, 95% CI, -4.46 to - 0.18; p = 0.034; Cohen's d 0.53 95% CI, 0.04 to 1.02). Drop out rate and cumulative incidence of nausea was significantly higher in the duloxetine arm compared to the pregabalin arm.
CONCLUSION
This study provides further evidence on higher efficacy of duloxetine compared to pregabalin for the treatment of pain in patients with fibromyalgia. Future comprehensive pragmatic clinical trials are warranted.

Prurigo is a common skin disease characterised by erythematous macules and papules/nodules with severe pruritus. We report here two cases with treatment-resistant prurigo that were successfully treated with duloxetine hydrochloride, a serotonin-norepinephrine reuptake inhibitor. In vivo experiments with a mouse model of prurigo-like inflammation showed that duloxetine hydrochloride ameliorated not only scratching behaviours, but also skin inflammation. Duloxetine hydrochloride appears to be useful for treating prurigo via modulating itch signals and immune responses.

Review
INTRODUCTION
Generalized Anxiety Disorder (GAD) is a common psychiatric condition, characterized by the presence of general apprehensiveness and excessive worry. Current management consists of a range of pharmacological and psychological treatments. However, many patients do not respond to first-line pharmacological treatments and novel anxiolytic drugs are being developed.
AREAS COVERED
In this review, the authors first discuss the diagnostic criteria and epidemiology of GAD. The effective pharmacological treatments for GAD and their tolerability are addressed. Current consensus guidelines for treatment of GAD are discussed, and maintenance treatment, the management of treatment resistance, and specific management of older adults and children/adolescents are considered. Finally, novel anxiolytics under development are discussed, with a focus on those which have entered clinical trials.
EXPERT OPINION
A range of effective treatments for GAD are available, particularly duloxetine, escitalopram, pregabalin, quetiapine, and venlafaxine. There is a limited evidence base to support the further pharmacological management of patients with GAD who have not responded to initial treatment. Although many novel anxiolytics have progressed to clinical trials, translation from animal models has been mostly unsuccessful. However, the potential of several compounds including certain psychedelics, ketamine, oxytocin, and agents modulating the orexin, endocannabinoid, and immune systems merits further study.

Hyponatremia can be asymptomatic or have a wide range of clinical presentations such as headaches, muscle cramps, nausea, seizures, coma, cerebral edema and may even result in death. Despite it has been suggested that duloxetine has a relatively less risk of hyponatraemia, the number of case reports are increasing. A 45- year old female patient with complaints of fear, anxiety, sleeplessness and headache was started on duloxetine (30 mg/day). In the first week of the treatment, she was admitted to the emergency service with dizziness, dry mouth, polyuria and polydipsia. She had to be transferred to the intensive care unit because of agitation, loss of consciousness and a generalized tonic-clonic seizure. Blood levels of Sodium (Na+), Potassium (K+) and Chlorine (Cl-) were, respectfully, 121 mmol/L, 2.7 mmol/L and 87 mmol/L. Brain imaging displayed cerebral edema. Electrolyte levels were regulated with saline infusions. Amitriptyline was initiated for the ongoing headache and anxiety. In outpatient visits, hyponatremia did not recur in the following 3 months. Low dose duloxetine was associated with severe hyponatremia signs and symptoms in an individual who was not previously considered as high risk for hyponatraemia. The patient's history did not reveal any complaints related to hyponatremia when she was treated with sertraline two years ago. Based on these, we discussed the risk factors for hyponatremia and risky antidepressant classes.
