Intrarenal epidermoid cyst mimicking a cystic renal cell carcinoma: A case report and review of literature.

Key Clinical Message: This case highlights the diagnostic pitfalls that can occur when evaluating complex cystic renal masses. Distinguishing epidermoid cysts from renal cell carcinoma is difficult but imperative to guide conservative management when appropriate, avoiding unnecessary nephrectomy. Abstract: Renal epidermoid cysts are extremely rare, with only 12 cases reported in the literature. Their radiographic features often resemble cystic renal cell carcinoma, frequently prompting unnecessary nephrectomy. A 64-year-old man with a history of nephrolithiasis presented with left flank pain and hematuria. Imaging revealed a complex cystic renal mass suspicious for renal cell carcinoma. Following left radical nephrectomy, histopathology examination revealed a benign epidermoid cyst. Renal presentation of epidermoid cyst poses unique diagnostic and therapeutic challenges. Possible pathogenesis includes ectopic epidermal implantation during embryogenesis or squamous metaplasia following chronic irritation or deficiency. Radiographic distinction from concerning entities like renal cell carcinoma is difficult but imperative to avoid extensive surgery. This case highlights the diagnostic pitfalls and management considerations for renal epidermoid cysts. Additional study of clinical and imaging factors that distinguish epidermoid cysts from renal cell carcinoma can guide conservative management when appropriate, avoiding unnecessary nephrectomy for benign disease.

Acquired arteriovenous hemangioma on the nose of a middle-aged man: A case report.

Arteriovenous hemangioma is a rare, benign vascular lesion that presents with an asymptomatic red or violaceous papule which is frequently asymptomatic but pruritus, pain and enlargement may be seen in some patients. In histology it is composed of thick-walled and thin-walled blood vessels distributed in superficial and mid dermis. The treatment of choice in such cases is complete excision and recurrence is rare. In this article we describe an acquired form of arteriovenous hemangioma on the nose of a middle-aged man.

Case Report: Gastrointestinal Basidiobolomycosis in a Young Girl with Cystic Fibrosis and Celiac Disease.

Basidiobolomycosis is an uncommon fungal infection that has been reported in the literature mainly as a cause of infection in the skin and subcutaneous tissue. Intraabdominal infections have been reported in tropical and subtropical areas in the Middle East, such as Iran and Saudi Arabia, and in the United States. Our patient was a 6-year-old girl with cystic fibrosis and celiac disease who was referred to our department with a history of chronic abdominal pain. In the imaging studies of the abdomen and pelvis, a large retroperitoneal mass was reported in the right upper part of the abdomen with involvement of the duodenum and the mesentery of the small and large intestines, as well as the superior mesenteric vessels, and was diagnosed as basidiobolomycosis through biopsy. Because of the large unresectable mass, the patient was first treated with antifungal drugs for 2 months and then surgical resection was performed. The main point in the management of these patients is a combination of antifungal therapy and surgical resection. In some patients, complex surgeries such as the Whipple procedure may be performed to appropriately manage intraabdominal infections.

Prevalence of Psychological Distress and Posttraumatic Stress Symptoms and Associated Factors in Hospitalized Iranian COVID-19 Patients.

Objectives: To investigate the prevalence of psychiatric symptoms/distress and posttraumatic stress (PTS) and associated factors among inpatients with COVID-19 before discharge from the hospital. Methods: This cross-sectional study was conducted in two teaching referral hospitals in Babol, Iran from July to November 2020. The subjects were inpatients diagnosed with COVID-19 who were clinically stable. Before their discharge from the hospital, the patients completed three questionnaires: demographic data, Brief Symptom Inventory, and Primary Care Post Traumatic Stress Disorder Screen for Diagnostic and Statistical Manual-5. Results: The subjects were 477 inpatients diagnosed with COVID-19 including 40 (8.4%) admitted to intensive care units. Their average age was 60.5±17.9 years; 53.9% were female. Most had symptoms of significant psychological distress (96.0%) and PTS (8.1%) prior to discharge. A higher level of education (-0.18; standard error (SE) = 0.05; p < 0.001) was a negative predictor of psychiatric distress. The admission to intensive care units (0.86; SE = 0.08; p< 0.001) was a positive predictor of psychiatric distress. Conclusions: Most COVID-19 inpatients suffered significant psychiatric distress and PTS symptoms before discharge. Appropriate mental health crisis interventions are recommended for COVID-19 patients during hospitalization.

Thyroid Stimulating Hormone, T3 and T4 Population-based Reference Range and Children Prevalence of Thyroid Dysfunction: First Report from South of Iran.

Background & Objective: The TSH reference range's validity affects the thyroid dysfunction diagnosis. The primary objective of this study is to determine the reference range, which is established according to age and region. Methods: The data were collected retrospectively from people over the age of one who visited Motahari Clinic for routine health checkups between August 2017 and October 2019. TSH, T4, T3, personal drug usage, and thyroid history were collected. After excluding subjects with thyroid diseases and outliers, 1392 participants were analyzed. Hormone intervals of men and women ≥1 year old have been determined using the non-parametric method. Results: The non-disease subjects' TSH, T3, and T4 reference ranges were 0.64 to 5.94 lU/mL, 0.91 to 2.47 ng/dL, and 5.53 to 12.48 g/dL, respectively. According to this range, total thyroid dysfunction prevalence in our study in children was 8.94%. There was no significant difference between TSH, T4 level, and gender in the non-disease population (P=0.46 and 0.13, respectively), but there was a statistical difference between sex and T3 (P =0.03). Our study also illustrates that for subjects under 18 years old and older, the hormones (TSH, T3, T4) concentration are statistically different (P≤0.001). Conclusion: We found a statistically difference between hormone values younger and older than age 18 (P=≤0.01); therefore, it is not appropriate to use the same reference range for children younger than age 18 and adults. There was male predominance in the population aged1-18 years old.

Recurrent Infections and Immunodeficiency Caused by Severe Pancytopenia Associated with a Novel Life-Threatening Mutation in Hypoxia-Upregulated Protein 1.

HYOU1 encodes a protein from the endoplasmic reticulum chaperone proteins, expressed to protect cellular mechanisms from stress such as hypoxia, insufficient energy and excessive or insufficient substances, and to restore cell homeostasis. In this study, we report a novel pathogenic variant in HYOU1. The proband, the second patient with pathogenic variant in HYOU1, was a female born to consanguineous parents. A novel homozygous pathogenic variant in HYOU1 (NM_001130991.3: c.1456C>T; p.Arg486Cys) was identified, causing anemia, thrombocytopenia and severe panleukopenia and immunodeficiency in the second month of age, leading to consistent high-grade fever, regression of brain functions and recurrent infections; ultimately resulting in the patient expiring at three and half months of age. Both parents are heterozygous for this variant and have no issues related to this study.

Liver Biomarkers Assay in COVID-19 Cases: A Comparison Study between Alive and Dead Patients.

BACKGROUND: Identifying effective biomarkers plays a critical role on screening; rapid diagnosis; proper managements and therapeutic options, which is helpful in preventing serious complications. The present study aimed to compare the liver laboratory tests between alive and dead hospitalized cases for prediction and proper management of the patients. METHODS: This retrospective, cross sectional study consists of all deceased patients admitted in one center in Shiraz, Iran during 19 Feb 2020 to 22 Aug 2021. For further comparison, we selected a 1:2 ratios alive group randomly. RESULTS: Overall, 875 hospitalized cases died due to COVID-19. We selected 1750 alive group randomly. The median age was significantly higher in died group (65.96 vs 51.20). Regarding the laboratory findings during the hospitalization ALT, AST, Bili.D were significantly higher in non-survivors than survivors but Albumin was less in deceased patients. It was revealed elevated levels of Albumin, AST, Bili.T and Bili.D were associated with increasing the risk of in hospital death. Moreover, the predictive effect of ALP and Bili.D had significantly more than others with high sensitivity and specify. CONCLUSION: We found patients with COVID-19 have reduced serum albumin level, and increase ALT and AST. The current results revealed abnormal liver chemistries is associated with poor outcome, which highlighted the importance of monitoring these patients more carefully and should be given more caution.

Phenotypic spectrum of autosomal recessive Keratitis-Ichthyosis-Deafness Syndrome (KIDAR) due to mutations in AP1B1.

Inborn errors in copper metabolism result in a diverse set of abnormalities such as Wilson disease and MEDNIK syndrome. Homozygous pathogenic variants in AP1B1 lead to KIDAR (Keratitis-Ichthyosis-Deafness Syndrome). The main phenotypic features of KIDAR are ichthyosis, keratitis, erythroderma, and progressive hearing loss accompanied by developmental delay and failure to thrive. Herein, we describe a six-and-a-half-year-old boy with KIDAR caused by a novel pathogenic variant in AP1B1 (NM_001127.4:c.1263C > A, p.Tyr421*). The proband presented with ichthyosis, erythroderma, palmoplantar keratoderma, hearing loss, and corneal scarring. He also had hypotonia, global developmental delay, and photophobia. Lastly, we review all of the previously reported cases and the clinical features associated with KIDAR.

Concomitant BK virus infection and visceral Leishmaniasis in a pediatric liver transplant recipient.

BACKGROUND: Solid organ transplant recipients are vulnerable to various unusual infections. Visceral Leishmaniasis (VL) is a protozoal opportunistic infection, which may affect the immune-suppressed hosts and solid organ transplant recipients. The BK virus infection is an evolving challenge in kidney transplant recipients. However, there are very few reports of BK virus (BKV) nephropathy involving the native kidney in liver transplant recipients. To the best of our knowledge, this is the first report of the simultaneous occurrence of these rare infections in a liver transplant recipient. CASE REPORT: The patient was a 9-year-old girl, a case of liver transplantation who presented with the incidental finding of proteinuria, azotemia, and cytopenia. Investigations revealed that she had concomitant BKV nephropathy and visceral leishmaniasis. Both infections were successfully treated. CONCLUSION: BK virus should be considered as a cause of nephropathy in liver transplant recipients. The presenting features of fever, cytopenia, and splenomegaly in a post-transplant patient should remind of unusual infections such as VL other than the common post-transplant conditions.

The regulation of CD47-SIRPα signaling axis by microRNAs in combination with conventional cytotoxic drugs together with the help of nano-delivery: a choice for therapy?

CD47, a member of the immunoglobulin superfamily, is an important "Don't Eat-Me" signal in phagocytosis process [clearance of apoptotic cells] as well as a regulator of the adaptive immune response. The lower level of CD47 on the cell surface leads to the clearance of apoptotic cells. Dysregulation of CD47 plays a critical role in the development of disorders, particularly cancers. In cancers, recognition of CD47 overexpression on the surface of cancer cells by its receptor, SIRPα on the phagocytic cells, inhibits phagocytosis of cancer cells. Thus, blocking of CD47-SIRPα signaling axis might be as a promising therapeutic target, which promotes phagocytosis of cancer cells, antigen-presenting cell function as well as adaptive T cell-mediated anti-cancer immunity. In this respect, it has been reported that CD47 expression can be regulated by microRNAs (miRNAs). MiRNAs can regulate phagocytosis of macrophages apoptotic process, drug resistance, relapse of disease, radio-sensitivity, and suppress cell proliferation, migration, and invasion through post-transcriptional regulation of CD47-SIRPα signaling axis. Moreover, the regulation of CD47 expression by miRNAs and combination with conventional cytotoxic drugs together with the help of nano-delivery represent a valuable opportunity for effective cancer treatment. In this review, we review studies that evaluate the role of miRNAs in the regulation of CD47-SIRPα in disorders to achieve a novel preventive, diagnostic, and therapeutic strategy.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).

Acute necrotizing glomerulonephritis associated with COVID-19 infection: report of two pediatric cases.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is thought to cause kidney injury via a variety of mechanisms. The most common reported kidney injury following COVID-19 infection is acute tubular injury (ATI); however, the procoagulant state induced by the virus may also damage the kidneys. CASE-DIAGNOSIS/TREATMENT: Herein, we report two cases of acute necrotizing glomerulonephritis (GN) with fibrinoid necrosis in the context of COVID-19 infection. The one with more chronic features in the kidney biopsy progressed to permanent kidney failure but the second one had an excellent response to glucocorticoid pulse therapy with subsequent normal kidney function at 2-month follow-up. CONCLUSIONS: Both reported cases had an acute presentation of kidney injury with positive nasopharyngeal PCR test for COVID-19. Based on the data review by the researchers, this is the first report of acute necrotizing GN associated with COVID-19 infection.

Cutaneous Vesicular of COVID-19 in Two Burn Patients.

Despite the whole world's effort for controlling an ongoing global outbreak caused by new corona virus; it is still a major public health issue. Any hospitalized patient or outpatient in burn departments should be considered as a potential infectious source of COVID-19, which may cause an overwhelming of disease. However, there are no previous experiences about COVID-19 in burn patients all over the world, and here we reported two burn cases at Amir-al-Momenin Burn Hospital Affiliated to Shiraz University of Medical Sciences, Shiraz, Iran with skin manifestations, which were detected as a rarely COVID-19 symptom. A 13-year-old girl [total body surface area (TBSA): 18%] and a 37-year-old woman (TBSA: 30%) who had burn injuries by gas explosion and car accident, respectively were enrolled. After admission, some vesicular injuries were visible in burn area. To confirm, skin biopsy specimens were either sent for histopathology examination or for real time polymerase chain reaction (PCR) as follow: Herpes Simplex Virus (HSV), chicken pox, and potassium hydroxide (KOH) for fungal infections. All test results were negative. Although they had no symptoms of COVID-19, two swabs from nasopharyngeal and oropharyngeal samplings were taken, the result was negative either. Specimens were obtained from vesicular lesions for qRT-PCR assay of COVID-19. According to the molecular results for vesicular samples, all the results were positive for COVID-19. Unlike all other COVID-19 patients who have respiratory symptoms, SARS-COV-2 appeared by cutaneous vesicular and blisters in two burn cases.

A First Case of Acute Cerebellitis Associated with Coronavirus Disease (COVID-19): a Case Report and Literature Review.

Novel coronavirus (severe acute respiratory syndrome-coronavirus-2: SARS-CoV-2), which originated from Wuhan, China, has spread to the other countries in a short period of time. We report a 47-year-old male who was admitted to our hospital due to suffering from progressive vertigo and ataxia for 7 days prior to the admission. Neurological examination revealed cerebellar dysfunction, and brain magnetic resonance imaging (MRI) depicted edema of the cerebellar hemisphere associated with leptomeningeal enhancement. Cerebrospinal fluid (CSF) analysis showed mild lymphocytic pleocytosis, elevated protein, and lactate dehydrogenase. SARS-CoV-2 RNA was detected in the oropharyngeal/nasopharyngeal and CSF specimens. As a result, treatment with lopinavir/ritonavir was initiated, and patient symptoms and signs improved significantly during the course of hospitalization. To the best of our knowledge, this is the first case of acute cerebellitis associated with COVID-19 disease which is reported in the literature so far.

Epidemiological and clinical features of 2019 novel coronavirus diseases (COVID-19) in the South of Iran.

BACKGROUND: In March 2020, the WHO declared the novel coronavirus (COVID-19) outbreak a global pandemic. Although the number of infected cases is increasing, information about its clinical characteristics in the Middle East, especially in Iran, a country which is considered to be one of the most important focal points of the disease in the world, is lacking. To date, there is no available literature on the clinical data on COVID-19 patients in Iran. METHODS: In this multicenter retrospective study, 113 hospitalized confirmed cases of COVID-19 admitted to university affiliated hospitals in Shiraz, Iran from February 20 to March 20 were entered in the study. RESULTS: The mean age was 53.75 years and 71 (62.8%) were males. The most common symptoms at onset were fatigue (75: 66.4%), cough (73: 64.6%), and fever (67: 59.3%). Laboratory data revealed significant correlation between lymphocyte count (P value = 0.003), partial thromboplastin time (P value = 0.000), international normalized ratio (P value = 0.000) with the severity of the disease. The most common abnormality in chest CT scans was ground-glass opacity (77: 93.9%), followed by consolidation (48: 58.5%). Our results revealed an overall 8% (9 out of 113 cases) mortality rate among patients, in which the majority was among patients admitted to the ICU (5: 55.6%). CONCLUSION: Evaluating the clinical data of COVID-19 patients and finding the source of infection and studying the behavior of the disease is crucial for understanding the pandemic.

Clinical and laboratory findings from patients with COVID-19 pneumonia in Babol North of Iran: a retrospective cohort study.

BACKGROUND: In December 2019, China has experienced an outbreak of novel coronavirus disease 2019 (COVID-19). Coronavirus has now spread to all of the continents. We aimed to consider clinical characteristics, laboratory data of COVID-19 that provided more information for the research of this novel virus. METHODS: We performed a retrospective cohort study on the clinical symptoms and laboratory findings of a series of the 100 confirmed patients with COVID-19. These patients were admitted to the hospitals affiliated to Babol University of Medical Sciences (Ayatollah Rohani, Shahid Beheshti and Yahyanejad hospitals) form 25 February 2020 to 12 March 2020. RESULTS: Nineteen patients died during hospitalization and 81 were discharged. Non-survivor patients had a significantly higher C-reactive protein (CRP) (MD: 46.37, 95% CI: 20.84, 71.90; P = 0.001), white blood cells (WBCs) (MD: 3.10, 95% CI: 1.53, 4.67; P < 0.001) and lower lymphocyte (MD: -8.75, 95% CI: -12.62, -4.87; P < 0.001) compared to survivor patients Data analysis showed that comorbid conditions (aRR: 2.99, 95% CI: 1.09, 8.21, P = 0.034), higher CRP levels (aRR: 1.02, 95% CI: 1.01, 1.03, P = 0.044), and lower lymphocyte (aRR: 0.82, 95% CI: 0.73, 0.93, P = 0.003) were associated with increased risk of death. CONCLUSIONS: Based on our findings, most non-survivors are elderly with comorbidities. Lymphopenia and increased levels of WBCs along with elevated CRP were associated with increased risk of death. Therefore, it is best to be regularly assessed these markers during treatment of COVID-19 patients.

Carnosine and Histidine Supplementation Blunt Lead-Induced Reproductive Toxicity through Antioxidative and Mitochondria-Dependent Mechanisms.

Lead (Pb)-induced reproductive toxicity is a well-characterized adverse effect associated with this heavy metal. It has been found that Pb exposure is associated with altered spermatogenesis, increased testicular degeneration, and pathological sperm alterations. On the other hand, it has been reported that Pb-induced reproductive toxicity is associated with increased reactive oxygen species (ROS) formation and diminished antioxidant capacity in the reproductive system. Hence, administration of antioxidants as protective agents might be of value against Pb-induced reproductive toxicity. This study was designed to investigate whether carnosine (CAR) and histidine (HIS) supplementation would mitigate the Pb-induced reproductive toxicity in male rats. Animals received Pb (20 mg/kg/day, oral, 14 consecutive days) alone or in combination with CAR (250 and 500 mg/kg/day, oral, 14 consecutive days) or HIS (250 and 500 mg/kg/day, oral, 14 consecutive days). Pb toxicity was evident in the reproductive system by a significant increase in tissue markers of oxidative stress along with severe histopathological changes, seminal tubule damage, tubular desquamation, low spermatogenesis index, poor sperm parameters, and impaired sperm mitochondrial function. It was found that CAR and HIS supplementation blunted the Pb-induced oxidative stress and mitochondrial dysfunction in the rat reproductive system. Thereby, antioxidative and mitochondria-protective properties serve as primary mechanisms for CAR and HIS against Pb-induced reproductive toxicity.

Spontaneous Rupture of Renal Cell Carcinoma in Pregnancy, Surgical Management With Fetal Preservation:A Case Report.

Spontaneous Retroperitoneal hemorrhage in pregnancy is a rare condition. Renal angiomyolipoma (RA) is the most common cause of this hemorrhage. To the best of our knowledge, this is the first reported case of Wunderlich syndrome (WS) due to renal cell carcinoma (RCC) diagnosed in the second trimester of pregnancy.

Dual effects of sulfasalazine on rat sperm characteristics, spermatogenesis, and steroidogenesis in two experimental models.

There are reports of sulfasalazine (Salazosulfapyridine; SASP)-induced reproductive toxicity, but there it is not known whether the SASP molecule or its intestinal metabolites are responsible for this effect. Rats received SASP (150, 300, and 600mg/kg) for 60 consecutive days (in vivo). Additionally, epididymal sperm was isolated and incubated with SASP (10µM-1600µM) (in vitro). Markers of oxidative stress, mitochondrial function, and sperm functionality, along with testis histopathology as well as several steroidogenic genes and proteins, including steroidogenic acute regulatory (StAR) protein, cytochrome P450 side chain cleavage enzyme (P450scc; Cyp11a), 3ß-hydroxysteroid dehydrogenase (3ß-HSD), 17ß-hydroxysteroid dehydrogenase (17ß-HSD) were measured. SASP toxicity was evident as shown by severe testicular histopathological alterations, along with poor sperm parameters and increased markers of oxidative stress. Plasma testosterone level and steroidogenesis-related gene and protein (StAR, 3-beta-HSD, 17-beta-HSD) expressions, as well as mitochondrial membrane potential, were significantly decreased at high doses of SASP (in vivo). Interestingly, in vitro treatment of sperm with SASP not only caused no significant detrimental effect on rat sperm but also increased parameters of sperm functionality and decreased markers of oxidative stress. SASP had paradoxical actions on the rat sperm in these experimental models. The findings might be useful in understanding the mechanism(s) of SASP-induced reproductive toxicity. The present findings have opened a new molecular window into the relationship between disrupted steroidogenesis and mammalian reproduction indices and also are vital regarding clinical administration of SASP and human reproductive health.

Mechanism of valproic acid-induced Fanconi syndrome involves mitochondrial dysfunction and oxidative stress in rat kidney.

AIM: Drug-induced kidney proximal tubular injury and renal failure (Fanconi syndrome; FS) is a clinical complication. Valproic acid (VPA) is among the FS-inducing drugs. The current investigation was designed to evaluate the role of mitochondrial dysfunction and oxidative stress in VPA-induced renal injury. METHODS: Animals received VPA (250 and 500 mg/kg, i.p., 15 consecutive days). Serum biomarkers of kidney injury and markers of oxidative stress were assessed. Moreover, kidney mitochondria were isolated and mitochondrial indices, including succinate dehydrogenase activity (SDA), mitochondrial depolarization, mitochondrial permeability transition pore (MPP), reactive oxygen species (ROS), lipid peroxidation (LPO), mitochondrial glutathione, and ATP were determined. RESULTS: Valproic acid-treated animals developed biochemical evidence of FS as judged by elevated serum gamma-glutamyl transferase (γ-GT), alkaline phosphatase (ALP), creatinine (Cr), and blood urea nitrogen (BUN) along with hypokalaemia, hypophosphataemia, and a decrease in serum uric acid. VPA caused an increase in kidney ROS and LPO. Renal GSH reservoirs were depleted and tissue antioxidant capacity decreased in VPA-treated animals. Renal tubular interstitial nephritis, tissue necrosis, and atrophy were also evident in VPA-treated rats. Mitochondrial parameters including SDA, MMP, GSH, ATP and MPP were decreased and mitochondrial ROS and LPO were increased with VPA treatment. It was found that carnitine (100 mg/kg, i.p.) mitigated VPA adverse effects towards the kidney. CONCLUSIONS: These data suggest that mitochondrial dysfunction and oxidative stress contributed to the VPA-induced FS. On the other hand, carnitine could be considered a potentially safe and effective therapeutic option in attenuating VPA-induced renal injury.

The effect of melatonin on the lipid levels in menopausal women: A double-blind, controlled, clinical trial.

BACKGROUND: Cardiovascular diseases are the major public health problem in many countries and are responsible for more than half of the deaths in above 50-year-old women. The most common curable risk factor of these disorders is hypoestrogenemia resulting from menopause. The present study aimed to investigate the effect of melatonin on plasma lipid levels in menopausal women. MATERIALS AND METHODS: The present double-blind, placebo-controlled, clinical trial was conducted in 2013-2014 on 240 menopausal women between 40 and 60 years old referring to the Gynecology and obstetrics clinics of Shiraz University of Medical Sciences who were randomly divided into two groups. The intervention group received 3 mg melatonin tablets and the control group received the placebo for 3 months. The data were gathered using the demographic information questionnaire and lipid profile test before and 3 months after the intervention. Then, the data were analyzed through the SPSS statistical software (version 16). The repeated measures analysis of variance, the least significant difference, the independent-sample t, the Chi-square, and Fisher's exact tests were done for data analysis. RESULTS: The two study groups were similar regarding the demographic and clinical variables at the beginning of the study. In the melatonin group, the amount of triglyceride increased from 140.34 ± 48.29 before the study to 151.24 ± 54.60 3 months after the intervention and no significant difference was observed between the two groups in this regard (confidence interval [CI] = 95%, P > 0.05). In addition, no significant difference was found between the two groups concerning low-density lipoprotein cholesterol level (CI = 95%, P = 0.125). CONCLUSION: Melatonin was not effective in reduction of lipid levels. However, further controlled studies are needed to be conducted on the issue.
