Co-administration of saffron and chamomile: to determine the efficacy as an adjuvant therapy for mild to moderate depression in human subjects. A pilot randomized clinical trial.

OBJECTIVE: To determine the combined effects of chamomile and saffron herbs as an adjuvant therapy in patients with metabolic alterations associated with mild to moderate depression. METHODS: The prospective, randomised, blinded, end-point pilot study was conducted at the Aga Khan University, Karachi, from August to October 2020, and comprised patients with mild to moderate depression with or without diabetes, hypertension and dyslipidaemia. The subjects were randomised into intervention group A, which was given herbal tea sachets containing saffron 1mg and chamomile 20mg for twice a day oral use for a month along with medications, and control group B, which was advised to continue their routine medications. Data was collected at baseline and post-intervention using Patient Health Questionnaire-9 for assessing depression severity, and blood samples for cholesterol estimations. Data was analysed using SPSS 20. RESULTS: Of the 50 subjects, 25(50%) were in each of the two groups. Cholesterol, high-density lipoprotein, low-density lipoprotein and depression values were significantly better in group A than in group B (p<0.05). CONCLUSIONS: Potential benefits of combined doses of chamomile and saffron were found in depressive patients by improving metabolic alterations.

A randomized clinical trial to test efficacy of chamomile and saffron for neuroprotective and anti-inflammatory responses in depressive patients.

Depression is one of the common psychiatric problems in growing world population caused by long-term stressful events that may trigger the down regulation of neurogenesis. The pathogenesis of depression initially relies on serotonin deficiency which is associated with depressive feelings. Tryptophan (TRP) depletion participate crucial role in inducing depressive symptoms. Long-term reduction of 5-HT may disseminate to high sensitivity of MDD and alters the level of BDNF. Some studies have also revealed the strong association between excessive neuroinflammation and BDNF levels, due the release of pro-inflammatory cytokines. The treatment approach through FDA approved medicine has their own merits and drawbacks. Therefore, herbal alternatives have recently garnered attention for their effectiveness against depression. However, evidence-based synergic effects of antidepressant with different herbal agents are limited. The purpose of this study was to assess the synergistic effects of two well-known herbs, chamomile and saffron, as an adjuvant therapy in patients with mild to moderate depression. The present study was study randomized, open, blinded trial and comprised of 120 participants randomly allocated to control (n = 60) and test (n = 60). After consent, the patient health questionnaire- 9 (PHQ-9) was filled to obtain depression scores. The test participants were received herbal tea sachets twice a day for one month (20 mg Chamomile and 1 mg Saffron/sachet) along with routine medicines, while control participants were received only allopathic medications. Blood samples were taken before and after the treatment. The depressive symptoms improved significantly with both treatments. The effect of herbs enhanced the efficacy of medications and significantly improved PHQ-9 scale and BDNF while reduced the inflammatory markers (CRP) and TRP level in plasma thereby increased the availability of TRP in brain. It has been concluded that the herbal adjuvant therapy produced long term improvement against depression and enhanced the efficacy of allopathic treatment.

A narrative review on manifestations of gluten free casein free diet in autism and autism spectrum disorders.

Autism and Autism Spectrum Disorder (ASD) are specific neurological disorders that affect the brain, frequently characterised by challenging paediatric behaviour. The current narrative review using PubMed and Google Scholar was conducted in line with the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols, and comprised randomised controlled trials and clinical control trials with gluten-free, casein-free (GFCF) diets published till 2020. Of the 80 studies selected, 7(8.75%) were included in the review. It was observed that the gluten-free, casein-free diet was safe with therapeutic benefits in autistic children. Therefore, a tailored dietary approach can be a beneficial management regimen. The trials related to utility of gluten-free, casein-free diet among autistic children are sparse, with limited sampling size, and indication of bias in the findings. Therefore, larger cohort studies on gluten-free, casein-free trials are required to provide further insight into the therapeutic benefits of the diet.

Ocular COVID-19: Eyes as a Reservoir to Conceal and Spread SARSCoV- 2.

Ocular tissues can serve as a reservoir for the SARS-CoV-2 virus which can not only cause conjunctivitis but also serve as a source of infection transmission to others. Additionally, the eye and its tear drainage apparatus can track the SARS-CoV-2 from the eye into the respiratory tract of the patient. The potential ocular presence of the SARS-CoV-2 in the eye of a patient can target ACE2 receptors in the endothelium of the conjunctival vessels and use the lacrimal sac a potential space to evade immune detection and clinical isolation. The recently reported case of COVID-19 after the acquisition of SARS-CoV-2 from a COVID-19 patient should alert the healthcare professionals dealing with COVID-19 patients that wearing masks alone cannot guarantee protection against infection transmission. Further studies, like isolation of SARS-CoV-2 from the eyes of patients with COVID-19, are needed to identify the eyes as a potential source of SARS-CoV-2 infection transmission.
