Toxic Animal-Based Medicinal Materials Can Be Effective in Treating Endometriosis: A Scoping Review.

Animal toxins and venoms have recently been developed as cancer treatments possessing tumor cell growth-inhibitory, antiangiogenesis, and proapoptotic effects. Endometriosis is a common benign gynecological disorder in reproductive-age women, and no definite treatment for this disorder is without severe side effects. As endometriosis and malignant tumors share similar characteristics (progressive, invasive, estrogen-dependent growth, and recurrence), animal toxins and venoms are thought to be effective against endometriosis. The objective of this study was to outline studies using toxic animal-based medicinal materials (TMM) as endometriosis treatment and to explore its clinical applicability. Preclinical and clinical studies using TMM were searched for in four databases from inception to October 2020. A total of 20 studies of TMM on endometriosis were included. In eight clinical studies, herbal medicines containing TMM were effective in relieving symptoms of endometriosis, with no side effects. In twelve experimental studies, the main therapeutic mechanisms of TMM against endometriosis were proapoptotic, antiangiogenesis, estrogen level-reducing, and possible anti-inflammatory effects. TMM are thus considered promising sources for the development of an effective treatment method for endometriosis. Further studies are needed to clarify the therapeutic mechanism of TMM against endometriosis and to provide sufficient grounds for clinical application.

Oscillococcinum leading to angioedema, a rare adverse event.

Oscillococcinum is an alternative medicine prepared by serial dilution of wild duck heart and liver extracts. This preparation has been labelled as a 'non drowsy, homoeopathic medicine' that 'reduces the duration and severity of flu and flu-like symptoms'. Clinical evidence exists to support this claim and the product has not previously been reported to cause any serious adverse drug reactions. We bring to light, however, a case of angioedema in our patient who was using oscillococcinum for flu-like symptoms. Consumers must therefore exercise caution at the outset of allergy symptoms.

A pilot placebo-controlled, double-blind, and randomized study on the cognition-enhancing benefits of a proprietary chicken meat ingredient in healthy subjects.

BACKGROUND: It has long been postulated that the relative abundance of specific nutrients can affect cognitive processes and emotions. Newly described influences of dietary factors on neuronal function and synaptic plasticity have revealed some of the vital mechanisms that could be responsible for the action of diet on brain health and cognitive function. Here, through a double-blind, randomized, placebo-controlled trial, we asked if the newly discovered chicken meat ingredient-168 (CMI-168) could be beneficial to the cognitive function in healthy adults. METHODS: Normal, healthy subjects were supplemented with either placebo or CMI-168 for 6 weeks. The subjects were given a series of cognitive tests to examine their levels of cognitive functioning at the beginning and end of supplementation, as well as two weeks after termination of supplementation. The combination of these tests, namely Digit Span Backwards, Letter-Number Sequencing, and the Rey Auditory Verbal Learning Test (RAVLT), was used to assess the subjects' attention and working memory. For all comparisons, the probability level of p < 0.05 was taken as statistically significant using repeated measure 2-way ANOVA followed by Bonferroni post-hoc test. RESULTS: Overall, subjects supplemented with CMI-168 showed significantly (p < 0.01) better performance in all cognitive tests after 6 weeks' supplementation compared to control and such superior performance was maintained even 2 weeks after termination of supplementation. CONCLUSIONS: The present study reveals the cognition-enhancing properties of a recently developed chicken meat ingredient, likely arising from the promotion of attention and prefrontal cortex functions.

Desiccated thyroid extract compared with levothyroxine in the treatment of hypothyroidism: a randomized, double-blind, crossover study.

CONTEXT: Patients previously treated with desiccated thyroid extract (DTE), when being switched to levothyroxine (L-T4), occasionally did not feel as well despite adequate dosing based on serum TSH levels. OBJECTIVE: Our objective was to investigate the effectiveness of DTE compared with L-T4 in hypothyroid patients. DESIGN AND SETTING: We conducted a randomized, double-blind, crossover study at a tertiary care center. PATIENTS: Patients (n = 70, age 18-65 years) diagnosed with primary hypothyroidism on a stable dose of L-T4 for 6 months were included in the study. INTERVENTION: Patients were randomized to either DTE or L-T4 for 16 weeks and then crossed over for the same duration. OUTCOME MEASURES: Biochemical and neurocognitive tests at baseline and at the end of each treatment period were evaluated. RESULTS: There were no differences in symptoms and neurocognitive measurements between the 2 therapies. Patients lost 3 lb on DTE treatment (172.9 ± 36.4 lb vs 175.7 ± 37.7 lb, P < .001). At the end of the study, 34 patients (48.6%) preferred DTE, 13 (18.6%) preferred L-T4, and 23 (32.9%) had no preference. In the subgroup analyses, those patients who preferred DTE lost 4 lb during the DTE treatment, and their subjective symptoms were significantly better while taking DTE as measured by the general health questionnaire-12 and thyroid symptom questionnaire (P < .001 for both). Five variables were predictors of preference for DTE. CONCLUSION: DTE therapy did not result in a significant improvement in quality of life; however, DTE caused modest weight loss and nearly half (48.6%) of the study patients expressed preference for DTE over L-T4. DTE therapy may be relevant for some hypothyroid patients.

Thyroid storm due to inappropriate administration of a compounded thyroid hormone preparation successfully treated with plasmapheresis.

BACKGROUND: Thyroid storm (TS) is a rare life-threatening condition that is characterized by fever and altered mental status precipitated by endogenous or exogenous critical events, illness/injury, acute iodine load, and thyroid or non thyroid surgery. A large number of thyroid extracts are available and extensively used, even though they are not recommended clinically in hypothyroid or euthyroid patients. Consumption of such products can be dangerous and result in life-threatening TS. Here, we report a case of TS caused by inadvertent intake of very high dosages of triiodothyronine (T3) and thyroxine (T4) in compounded thyroid extracts. Plasmapheresis may be considered an option for the management of exogenous TS. PATIENT FINDINGS: A 62-year-old woman with no significant past medical history presented with severe myalgia, fever, tachycardia, and blood pressure of 170/80 mmHg, which precipitated to an altered mental state within 24 hours. Neurological examination did not reveal any focal deficit or any signs of meningeal irritation. Further investigation revealed that she had been taking thyroid supplements. The patient had accidentally been supplied with a batch of thyroid extract pills that had an inadvertently high content of T4. Her free T3 (FT3) and free T4 (FT4) levels were found to be very high beyond the laboratory readable range (FT3>30 pg/mL; FT4>6.06 ng/dL; thyrotropin [TSH]=0.07 IU/mL). SUMMARY: Three days post commencement of standard conservative management of TS, the patient developed posterior reversible encephalopathy syndrome, resulting in a seizure. She remained unresponsive and in a poor mental state. The confirmed exogenous etiology for TS led to a decision to conduct plasmapheresis. Plasmapheresis conducted for two consecutive days proved successful as a therapeutic measure for TS and improved her thyroid profile as well as her mental state. CONCLUSIONS: The inappropriate use of thyroid extracts in euthyroid and hypothyroid patients can result in life-threatening TS. Plasmapheresis is probably a life-saving treatment in patients who are exposed to amounts of thyroid hormone far in excess of that usually produced by the thyroid gland.

MS14, an Iranian herbal-marine compound for the treatment of multiple sclerosis.

MS14 is a natural herbal-marine drug, which has shown to slow down or halt the progression of multiple sclerosis (MS). This drug consists of 90% Penaeus latisculatus, 5% Apium graveolens, and 5% Hypericum perforatum L. Preclinically, the effects of MS14 have mostly been examined in an animal model of multiple sclerosis called experimental allergic encephalomyelitis (EAE). Clinical studies of the effects of MS14 in MS patients also showed that it could improve the patients' quality of life. MS14 is a safe drug in MS patients and might also be effective in the treatment of other neurodegenerative disorders with the same mechanisms.

A natural seaweed derived mineral supplement (Aquamin F) for knee osteoarthritis: a randomised, placebo controlled pilot study.

BACKGROUND: Osteoarthritis (OA) is a slowly destructive process that may be influenced by a nutritional mineral balance in the body. METHODS: This small, double blind, placebo controlled pilot study investigated the impact of treatment with a natural multi-mineral supplement from seaweed (Aquamin) on 6 minute walking distance (6 MWD), range of motion (ROM), and pain and joint mobility measured by the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index in subjects with moderate to severe OA of the knee during gradual withdrawal of non-steroidal anti-inflammatory drugs (NSAIDs) that were being used daily for pain management. Subjects (n = 29) with moderate to severe OA of the knee were randomised to receive either Aquamin (2400 mg/d) or Placebo for up to 12 weeks. RESULTS: Of the 29 subjects initially randomized, only 22 subjects proceeded to treatment due to 7 subjects not meeting study selection criteria at baseline. Fourteen subjects completed the study and an ITT analysis (n = 22) of the data showed no significant differences in WOMAC scores however, the data did reveal significant improvements in passive and active extension ROM (0.83 degrees +/- 1.54 vs. -1.54 degrees +/- 2.43; difference, 5.2 degrees +/- 2.2, p = 0.028) and 6 MWD (150 +/- 48 ft vs. 12.5 +/- 31.5 ft; difference, 136 +/- 57 ft, p = 0.03) in the Aquamin group compared to the placebo group; respectively, following a 50% reduction in NSAID use. The treatments were well tolerated and the adverse event profiles were not significantly different between the groups. CONCLUSION: This small preliminary study suggests Aquamin may increase range of motion and walking distances in subjects with OA of the knee and may allow partial withdrawal of NSAIDs over 12 weeks of treatment. Additional research is needed to confirm these preliminary observations. TRIAL REGISTRATION: NCT00755482.

[House-dust mites allergen for specific immunotherapy by oral administration: experimental study].

The oral medicinal form of house-dust allergen has been prepared with the use of new technology. To produce the preparation, the standard water-saline extract obtained from house-dust mites (Dermatophagoides farinae) allergen has been used. This preparation is chemically stable and does not lose its biological activity for 2 - 3 years of storage. The microbiological purity of the allergen meets the requirements for oral preparations. The allergen has proved to be safe in cases of prolonged administration and has no chronic toxicity. As shown with the use of immunochemical methods, the preparation has high immunogenicity and lower allergenicity. This preparation may be recommended for clinical trials on a limited circle of subjects.

[Fever and chills following intravenous administration of NeyTumorin--an unconventional xenogenous derived peptides extract].

We report a 54 year old patient who was recently diagnosed with retroperitoneal recurrence of colon carcinoma, and who was admitted because of fever and chills. Extensive work-up yielded no source of infection, multiple blood cultures were sterile, and symptoms resolved within two days. During hospitalization, it was learned that her symptoms appeared an hour after a drug named NeyTumorin was administered to her intravenously by an alternative medicine practitioner. NeyTumorin is part of cell therapy, which is an alternative medicine therapy involving the administration of farm animals derived preparation of peptides from several organs, including the diencephalon and hypophysis. This case underscores the risk of invasive alternative medicine treatments, which are not subject to adequate scrutiny by the health authorities.

[Evaluation of the complementary drug Factor AF2 as a supportive agent in management of advanced urothelial carcinoma. Prospective randomized multicenter study]. / Bewertung des Komplementärtherapeutikums Factor AF2 als Supportivum in der Behandlung des fortgeschrittenen Urothelkarzinoms. Prospektiv randomisierte Multicenterstudie.

This is a prospective randomized multicenter trial for evaluation of the biological response modifier Factor AF2 in advanced urothelial cancer treated with chemotherapy. Main aim of the study was the analysis of supportive effects. Additionally patients were examined with regard to tumor response, time to progression and survival. 106 patients with advanced urothelial cancer received chemotherapy with cisplatin and methotrexate. They were randomized for additional Factor AF2 (500 mg i.v., given at days 0-3, 7-10 and 11-14). Myelotoxicity was more common and severe in the group without Factor AF2 reaching statistical significance. Gastrointestinal side effects occurred in both groups, though grade III to IV toxicity was more common without Factor AF2. Overall remission rate was 38%, median survival 33 weeks, mean time to progression 20 weeks. There was no significant difference between the two groups with or without Factor AF2.

Immunotherapy in bee sting hypersensitivity. Bee venom versus wholebody extract.

Fifty-six patients with serologically confirmed bee sting hypersensitivity were treated for 1-3 years with either bee venom (BV) (31 patients) or wholebody extract (WBE) (25 per cent of re-exposed patients on BV-therapy showed a diminished reaction and 75% no reaction. Thirty-three per cent of re-exposed patients on WBE-therapy developed an unchanged or worse reaction, 42% a diminished reaction and 25% no reaction at all. An initial rise in BV-specific IgE was observed in BV-treated patients, whereas IgE levels after 1 year of treatment lay significantly below pretreatment values in both treatment groups. BV-specific IgG increased markedly in patients on BV-therapy and decreased slightly in those on WBE-therapy. The initial IgE increase induced by BV-therapy was insignificant in patients with high pretreatment levels of specific IgG-antibodies. Similarly, re-exposed patients with high BV-specific IgG showed no IgE increase, whereas a substantial rise in specific IgE was observed in those with low IgG. On the basis of clinical and serological results immunotherapy with BV is considered to be clearly superior to immunotherpy with WBE.
