Apocrine gland adenocarcinoma in a persian cat remission with homeopathic treatment: case report

Apocrine gland carcinomas are rare malignant neoplasms that occur in cats. Available treatment is surgical, would lead to total ablation of the external acoustic meatus and usually recurrent [1,2].Methodology:In December 2020, a homeopathic consultation of the feline, male, Persian, 13 years old, a history of the disease was reported, which started in 2015, adding up to six recurrences of tumor processes in the eyelids and recent formation in the left ear canal.The result of the histopathological examination confirmed apocrine adenocarcinoma.Prior to homeopathic treatment, tumors recurred despite surgical interventions and prophylactic treatment with trichloracetic acid.However, remaining formations were noted in the eyelids and ear canal. It has a rounded blackened shape in the upper right eyelid measuring 0.4 cm and the lower 0.2 cm, round. In the left ear canal, around 1.6 cm, in addition to 4 points scattered in the ear folds. Homeopathic treatment was started for two months with Arsenicum album30 cH, twice a day; Carcinosinum 200 cH, once a day, and complex containing Avena sativa4 cH, Echinacea angustifolia4 cH, Conium maculatum6 cH, Thuja officinalis6 cH and Silicea terra6 cH, four times a day. Every two months, the clinical picturewas reassessed, potenciesand frequencies readjusted.In a few months,there was complete remission of the tumor, recovery of welfare, and improvement in mood and appetite. The free and informed consent term was signed. There was no recurrence of tumors until May2022. Conclusion:This study proved to be effective, documented with photos and exams. Approaching a rare case may provide a new therapeutic possibility. The credibility of quality homeopathic case reports has been increasing due to methodological requirements using tools developed in recent studies.

Phenotypic Changes in Mammary Adenocarcinoma (4T1) cells In Vitro after Treatment with Carcinosinum.

OBJECTIVE: The present study aimed to identify possible phenotypic changes in 4T1 (murine mammary adenocarcinoma) cells in vitro, including viability, HER-2 (human epidermal growth factor receptor-type 2) expression, and metastatic potential, after treatment with Carcinosinum in different homeopathic dilutions (12cH, 30cH, 200cH) shaken mechanically in pure, sterile, water from a commercial stock dilution. METHODS: Treated cells were cultured in R10 medium, using 24-well plates, 105 cells per well, and treated with vehicle, Carcinosinum 12cH, 30cH or 200cH; untreated cells were used as the baseline control. After 24 hours of treatment, the percentage of apoptotic cells was analyzed by annexin V. Cell morphology was evaluated by microscopy after hematoxylin-eosin and Giemsa staining, whilst HER-2 expression was assessed using immunocytochemistry. The metastatic potential was determined by the expression and activity of the enzyme matrix metalloproteinase 9 (MMP-9) using zymography. The cytokine profile was established using the cytometric bead array method. RESULT: Treatment of 4T1 cells in vitro with Carcinosinum 30cH produced an increase in the number of annexin V-positive cells (apoptosis) and decreased expression of proactivated MMP-9. Cells treated with Carcinosinum 200cH presented hyper-expression of HER-2 on the plasma membrane, identified by immunocytochemistry. There were no differences in cytokine production among treatments. CONCLUSION: The data show promising results for Carcinosinum 30cH in vitro, but in vivo studies are also required to evaluate the role of tumor microenvironment in its effects.

Characterization of Antimonium crudum Activity Using Solvatochromic Dyes.

BACKGROUND: The mechanism by which highly diluted and agitated solutions have their effect is still unknown, but the development in recent years of new methods identifying changes in water and solute dipole moments is providing insights into potential modes of action. OBJECTIVE: The objective of the current study was to compare the biological effects of Antimonium crudum (AC) previously obtained by our group and already described in the literature with now measurable physico-chemical effects on solvatochromic dyes. METHODS: Different dilutions of AC and succussed water have been characterized with respect to their effect on the visible spectra of the solvatochromic dyes methylene violet (MV), a pyridinium phenolate (ET33), and a dimethylamino naphthalenone (BDN) compared with in-vitro action against Leishmania amazonensis-infected macrophages. RESULTS: Dye responses varied according to the dye used and the level of AC dilution and results were found to corroborate previously published in-vivo and in-vitro effects of AC. In addition, a very significant enhancement in the absorbance increase of MV was seen using the supernatant from AC 200cH-treated cells (15%; p < 0.0001) over that seen with AC 200cH itself (4%; p = 0.034), suggesting the amplification of ultra-high dilution effects by biological systems. Furthermore, supernatants from AC-treated cells increased the range of dilutions of AC that were capable of producing effects on the spectra of MV. The effect of AC dilutions on dye ET33 was eliminated by a weak electric current passed through potency solutions. CONCLUSION: The data confirm a correspondence between the biological effects of dilutions of AC in-vitro and physico-chemical effects on solvatochromic dyes as measured by changes in their visible spectra. Results also indicate high dilutions of AC are sensitive to exposure to electric currents and biological systems.
