Abstract

Acromegaly, which is characterised by an excess of growth hormone, is accompanied with comorbidities that produce considerable clinical dysfunction and a high mortality risk. Late diagnosis, as well as poor therapy tolerance and adherence, impede outcomes. The purpose of this work is to give a scoping evaluation of the benefits of existing treatments and to describe potential constraints that may restrict disease control or treatment continuity. Current therapies include transsphenoidal surgery, which is frequently followed by the use of synthetic somatostatin analogues or growth hormone receptor antagonists. In the case of nonresponsive patients or recurrent tumours, radiotherapy is used as an adjuvant to treatment. Despite therapeutic benefits, patient burdens result in an estimated one-quarter of patients stopping treatment or going missing, with up to 88 percent of these cases having uncontrolled disease. Although early disease detection and rapid treatment improve disease outcomes, long-term treatment adherence is crucial to results. The most cost-efficient and effective solutions include a thorough grasp of the particular patient's condition and treatment loads, as well as the patient's knowledge of their disease and the full utilisation of all health care team resources.

The most cost-efficient and effective solutions include a thorough grasp of the particular patient's condition and treatment loads, as well as the patient's knowledge of their disease and the full utilisation of all health care team resources. Provider awareness of factors influencing follow-up, the use of precision medicine, and the implementation of a team approach that actively involves patients, nurses, and physicians in treatment decisions, location convenient disease monitoring with co-morbidity treatment coordination, and home drug administration are all important factors in facilitating long-term treatment adherence.

Introduction

Acromegaly is caused by an excess of Growth Hormone (GH), which is usually the outcome of a pituitary tumour, or adenoma [1]. The estimated disease prevalence is 40 to 125 per million, with an annual incidence of 3 to 4 per million, affecting men and women equally [2]. However, where access to health care is universal, 17-21 percent of patients have been reported to be lost to treatment follow-up, with up to 88 percent of these having uncontrolled disease. Excess GH increases the creation of insulinlike Growth Factor-1 (IGF-I), notably in the liver. Excess GH and IGF-1 are substantially responsible for the disease’s clinical features and morbidity. High levels of IGF-1 stimulate chondrocyte and osteocyte activity, resulting in bone and cartilage overgrowth, acral enlargement, notably of the hands and feet, typical coarsening of facial features, joint laxity and remodelling, and increasing joint discomfort and arthritic symptoms.

The face, hands, and feet are the most affected by skin changes, puffiness, and edoema. There may also be oily skin with big pores, hypertrichosis, excessive perspiration, hyperpigmentation, skin tags, and psoriasis. Soft tissue growth and skeletal alterations encourage the formation of colon polyps, carpal tunnel syndrome, chest wall enlargement, and airway blockage, which frequently manifests as shortness of breath, sleep apnea, and poor oxygenation. Infertility can result from hypogonadism. IGF-1 also modulates myocytes, glucose metabolism, and insulin sensitivity, which manifests in a variety of diseases such as heart disease, hypertension, and diabetes. As a result, disease therapy is multifaceted. Individuals with acromegaly have a negative psychological status that is equivalent to patients with other chronic conditions, although body image difficulties are significantly worse for patients with acromegaly [3,4].

As with other uncommon disorders, the path to a specialist’s diagnosis and management of acromegaly, or referral to a pituitary centre, is frequently indirect. The onset of symptoms can be delayed and insidious, and diagnosis might take up to ten years. Disease co-morbidities contribute to dramatically increased mortality, which is 2-4 times greater than in the general population, but lifetime with managed GH is related with normal lifespan. Patients frequently come to several healthcare professionals, including endocrinologists, many of whom may be unfamiliar with this rare disease, resulting to a delay in diagnosis. As with other uncommon disorders, the path to a specialist’s diagnosis and management of acromegaly or referral to a pituitary clinic is frequently indirect. The onset of symptoms can be gradual and insidious, and diagnosis might take up to ten years. Untreated, illness co-morbidities contribute to dramatically increased mortality, which is 2-4 times greater than in the general population, but lifetime with managed GH is related with normal lifespan. It is not uncommon for patients to present to numerous healthcare professionals, including endocrinologists, many of whom may lack familiarity with this rare disease, resulting to a delay in diagnosis.

There is currently no treatment that has proved 100% efficacy. All have dangers and advantages, and each may have a distinct influence on patients. Although surgery is frequently used as the initial line of treatment, up to 68 percent of patients have residual disease or incomplete remission, necessitating further treatment following surgery [5]. When surgical remission is not obtained, medical therapy with either a mono or a combination therapy is used. Somatostatin analogues are typically used as monotherapy, whereas GH receptor antagonists and dopamine agonists are typically utilised in combination therapy.

Precision medicine based on individual biomarkers is becoming a viable alternative for improving outcomes. Detailed tumour histology can now provide quantification of somatostatin receptor subtype expression; describe the ratio of receptor expression; identify associated protein expression, such as AI expression of Aryl Hydrocarbon-Interacting Protein (AIP), beta arreston-1; quantify the percentage of proliferative activity markers, such as Ki-67 antigen and p53; and describe tumour granulation pattern, all of which have the potential to provide some guidance in predisposition. Similarly, some genomic polymorphisms have the ability to predict response to and liver problems associated with pegvisomant, and tumour dopamine receptors can assist predict response to dopamine agonist [6,7]. Soluble Klotho (sKlotho), a protein that inhibits insulin and IGF-1 signalling, has been discovered to be considerably higher in acromegaly patients and could be a potential clinical and molecular disease biomarker. The identification of new disease biomarkers may lead to more tailored illness therapies and surveillance in the future.

Acromegaly Drug Therapy

The development of SSAs (Octreotide and Lanreotide) and an SSA with a larger spectrum of activity (Pasireotide) has resulted in significantly improved treatment outcomes. Longacting SSAs addressed patient preferences for lowering the need for daily injections and, in some situations, allowing SSA administration at home. The future development of SSAs with a broader range of activity may reduce the rate of treatment failures even further [8]. The development of SSAs (Octreotide and Lanreotide) and an SSA with a larger spectrum of activity (pasireotide) has substantially improved treatment outcomes. The availability of longacting SSAs addressed patient preferences for lowering the need for daily injections and, in certain situations, allowing SSA administration at home. The development of SSAs with a broader range of activity in the future may reduce the prevalence of treatment failures even further [8].

Parenteral drugs should ideally be replaced or augmented with oral meds. In addition to removing the need for unpleasant injections and improving patient convenience, the use of oral drugs is anticipated to result in patient advantages similar to those seen in other chronic conditions. In a similar vein, replacing intravenous deferoxamine with oral deferasirox for the treatment of iron overload disorders resulted in increased adherence, superior clinical outcomes, higher quality of life, and pharmacoeconomic benefits. A new octreotide formulation employs unique Transient Permeability Enhancer technology, which allows octreotide to traverse the gastrointestinal wall in the small intestines via tight junctions. A recent phase 3 trial confirmed the safety and efficacy of twice-daily oral octreotide capsules. Most GH levels were lowered and acromegaly-related symptoms improved under therapy with oral octreotide. At the end of the 7-month treatment period, 65% of 151 evaluable individuals reached the primary endpoint of IGF-1 1.3 times upper limit of normal and mean integrated GH 2.5 ng/mL. Eighty-five percent of participants who joined a 6-month extension phase sustained this response for up to 13 months, suggesting therapy durability.

Anecdotally, patients describe difficulty scheduling injections around work schedules, family gatherings, and vacations, especially when the medication is linked with disruptive side effects such diarrhoea [9]. Family conflict has been described as a result of both disease and treatment-related difficulties. As a result, injection intervals are frequently lengthened or reduced to account for these difficulties. Some individuals experience ‘break through’ symptoms near the end of an injection cycle, which may necessitate a shorter treatment cycle or a second injection of a short-acting suppressive drug. Medical management may be disrupted due to supply shortages, insurance authorization issues, or the lack of a health care practitioner available to administer the injection. Due of disturbed work schedules and the potential for interfering with drug monitoring and compliance, treatment location may necessitate significant cost outlay. The requirement for continuing injections can be a persistent psychological reminder of a state of illness, adding a sensation of being powerless and losing one’s distinct identity by being a patient. Cognitive changes in older people might cause learning difficulties, bigger hands make administration devices harder to use, and visual deficiencies or presbyopia can make preparing and self-administering injectable drugs problematic. Patients must establish trust in the individuals who will be providing their shots. When confronted with an unknown nurse or a nurse that lacks experience in the preparation and administration of their injection, patients report more injection discomfort and more break-through symptoms. Although the terms adherence and compliance are commonly used interchangeably, they are rarely defined in the literature, and there is no gold standard for measuring them. Adherence implies an internal commitment, whereas compliance implies submitting to an external source. The World Health Organization’s Adherence Project defines adherence in terms of long-term therapy as “the extent to which a person’s behaviour in terms of taking medications, following a diet, and/ or implementing lifestyle changes corresponds with agreed recommendations from a health care provider” [10]. In wealthy countries, the average rate of adherence to long-term therapy for chronic illness is believed to be around 50%, and considerably lower elsewhere. Adherence and patient commitment to long-term therapy are crucial to patient outcomes, but they are difficult to achieve because no single strategy is effective for all patients in all conditions. Person-centered care evolved as a method of refocusing health care on the patient as an equal participant in care decisions in order to get the greatest results. The Picker Institute’s principles, which include respect for patients’ values, preferences, and expressed needs; coordination and integration of care; information, communication, and education; physical comfort; emotional support and alleviation of fear and anxiety; involvement of family and friends; transition and continuity, are central to this. Patient-centered care necessitated the participation and integration of all members of the health care team.

Poor adherence to a recommended medical therapy includes failing to complete prescriptions, failing to take doses as prescribed or at nontherapeutic dosing intervals, discontinuing treatment prematurely or to accommodate life events, and failing to attend clinic follow-up visits. The extent to which a patient chooses or is able to follow a prescribed treatment regimen is influenced by a variety of factors, many of which have been discussed in the preceding narrative; however, adherence and patient compliance decision making in general remain poorly understood , particularly in patients with acromegaly. A recent analysis of acromegaly registry patients in Germany indicated that inadequate patient motivation was the primary cause of poor acromegaly control, and additional efforts for patient education were recommended [11].

Conclusion

A critical component of promoting treatment adherence is selecting a treatment that minimises patient hassles while maximising benefits. Early disease detection and treatment reduce comorbidities and ensure the best outcomes, which may offset the overall expense of therapy. Precision medicine advancements and novel treatment methods may necessitate comprehensive histopathology at sites that undertake significant volumes of pituitary tumour resections. When long-term or lifelong treatment is required, developing a treatment strategy to promote adherence becomes difficult. Establishing meaningful, attainable quality of life goals with the patient may give a foundation for the establishment of an attainable treatment programme. Establishing an effective treatment programme necessitates early involvement of the patient’s local and primary health care teams, as well as coordination of the attending physician, nurse, and the patient.
