Therapeutic effect

Summary

Therapeutic effect refers to the response(s) after a treatment of any kind, the results of which are judged to be useful or favorable. This is true whether the result was expected, unexpected, or even an unintended consequence. An adverse effect (including nocebo) is the converse and refers to harmful or undesired response(s). What constitutes a therapeutic effect versus a side effect is a matter of both the nature of the situation and the goals of treatment. No inherent difference separates therapeutic and undesired side effects; both responses are behavioral/physiologic changes that occur as a response to the treatment strategy or agent. To maximize therapeutic effects (desired) and minimize side effects (undesired) requires recognition and quantification of the treatment in multiple dimensions. In the specific case of targeted pharmaceutical interventions, a combination of therapies is often needed to achieve the desired results. A 2015 review found that aloe vera exhibits therapeutic antioxidant, antimicrobial, immune boosting, antitumor, hypoglycemic, hypolipidemic, wound healing, and antidiabetic effects. Also in 2015, a review found that probiotics were beneficial in the treatment of irritable bowel syndrome. Again in 2015 another review found that Rituximab was therapeutic in the treatment of myasthenia gravis, an autoimmune disorder. A 2016 review found that the adjunctive use of standardized pharmaceutical-grade nutrients, known as nutraceuticals, had a therapeutic effect in patients with depression. Also in 2016, a review found that despite limited data botulinum toxin type A may be beneficial for the treatment of trigeminal neuralgia paroxysms and suggests further study. A 2014 review found there was a strong therapeutic benefit from stem cell therapy on organ recovery from injury and that it may also inhibit tumor growth. A 2015 review found that mindfulness based interventions had a therapeutic effect on stress reduction for mental illness.

High-risk human papillomavirus (HPV) encoding E6/E7-HPV oncogenes are responsible for a subgroup of head and neck squamous-cell carcinoma (HNSCC) and thus therapeutic E7-vaccines may be used to control HPV+HNSCC tumors. Herein we investigated the effects of an optimized nanoparticle-conjugated E7 long-peptide vaccine adjuvanted with CpG (NP-E7LP) in an orthotopic immunocompetent mouse model of HPV+HNSCC which is based on injection of HPV16 E6/E7-expressing mEERL95-cells into the submental space. In absence of surgery, vaccination performed before or after tumor-cell injection decreased tumor growth or prolonged mice survival only marginally, despite the high numbers of vaccine-induced circulating E7-specific IFN-gamma-secreting CD8(+) T-cells. This contrasts with the high-efficacy of NP-E7LP-vaccination reported in the genital and subcutaneous HPV16-E6/E7-expressing TC-1 models. Our data show that in a direct comparison, NP-E7LP-vaccination fully controlled TC-1, but not mEERL95, tumors subcutaneously growing in the flanks. Immune-cell infiltration was 10-fold higher in TC-1-tumors, than in mEERL95-tumors, suggesting that vaccine-induced CD8(+) T-cells can only poorly infiltrate mEERL95-tumors. Indeed, immunofluorescence staining of orthotopic mEERL95-tumors showed that CD3(+) T-cells are preferentially located peritumorally. However, when NP-E7LP-vaccination was performed after mEERL95-cell injection, but before resection of primary tumors, no postsurgical recurrence was observed and 100% of the mice survived until the experimental endpoint (day 70) in the NP-E7LP-vaccinated group. In contrast, we observed a 60% recurrence rate and only 35% survival in PBS-vaccinated mice. This suggests that removal of the primary tumor modified the tumor microenvironment, allowing a therapeutic effect of the vaccine-induced anti-tumor response. E7-vaccination combined with surgery may thus benefit patients with HPV+HNSCC.

Dual Targeting of the Autophagic Regulatory Circuitry in Gliomas with Repurposed Drugs Elicits Cell-Lethal Autophagy and Therapeutic Benefit

Douglas Hanahan, Ksenya Shchors, Aristea Massaras

The associations of tricyclic antidepressants (TCAs) with reduced incidence of gliomas and elevated autophagy in glioma cells motivated investigation in mouse models of gliomagenesis. First, we established that imipramine, a TCA, increased autophagy and conveyed modest therapeutic benefit in tumor-bearing animals. Then we screened clinically approved agents suggested to affect autophagy for their ability to enhance imipramine-induced autophagy-associated cell death. The anticoagulant ticlopidine, which inhibits the purinergic receptor P2Y(12), potentiated imipramine, elevating cAMP, a modulator of autophagy, reducing cell viability in culture, and increasing survival in glioma-bearing mice. Efficacy of the combination was obviated by knockdown of the autophagic regulatory gene ATG7, implicating cell-lethal autophagy. This seemingly innocuous combination of TCAs and P2Y(12) inhibitors may have applicability for treating glioma.

Therapy

A therapy or medical treatment (Both words, "Treatment" and "Therapy" are often abbreviated tx, Tx, or Tx) is the attempted remediation of a health problem, usually following a medical diagnosis. As a rule, each therapy has indications and contraindications. There are many different types of therapy. Not all therapies are effective. Many therapies can produce unwanted adverse effects. Medical treatment and therapy are generally considered synonyms. However, in the context of mental health, the term therapy may refer specifically to psychotherapy.

Therapeutic effect

Adverse effect

An adverse effect is an undesired harmful effect resulting from a medication or other intervention, such as surgery. An adverse effect may be termed a "side effect", when judged to be secondary to a main or therapeutic effect. The term complication is similar to adverse effect, but the latter is typically used in pharmacological contexts, or when the negative effect is expected or common. If the negative effect results from an unsuitable or incorrect dosage or procedure, this is called a medical error and not an adverse effect.
