Thalassemia refers to a serious medical condition that has a negative effect on the patient's quality of life (16). In patients with Thalassemia, measuring their health-related quality of life (HRQoL) is a unique approach to assess the patients' viewpoint of their condition and its influence on their lives (17).
When it comes to the availability of primary care services, there is a difference between rural and urban settings. As a result, the current study found that the majority of participants lived in urban areas due to the availability of primary care services, which is consistent with the findings of another Iranian study that found that the majority of Thalassemia patients came from urban areas (18). Furthermore, the place of residence was accombined with HRQoL in all domains and total HRQoL summary scores in this study. When compared to children from rural areas, children from urban areas showed greater HRQoL. One possible explanation is that the youngsters were under continual stress as a result of their long journeys and the transfusion treatments that they underwent throughout their hospitalization.
Iron over load complications was related to HRQoL in this investigation. These findings were not consistent with the study conducted in Thailand (5).
This present investigation found that the majority of patients experienced an Iron-overload problem, with the most likely causes being numerous transfusions, a decreased pre-transfusion hemoglobin level, insufficient chelation treatment, and severe anemia, as revealed by the findings. While other studies have reflected a significantly lower incidence rate of cardiomyopathy among their Thalassemia patients in Dubai (1.8 percent), this study found a significantly lower incidence rate of cardiomyopathy in their patients with a percentage of (1.8%) among their Thalassemia patients (12).
The comparatively high iron overload complication rate in Yemen might be illustrated by the fact that Thalassemia therapy is complicated, expensive, and difficult to obtain due to poverty, thus patients are unable to obtain iron chelating medicines, which assist to reduce the incidence of problems.
The findings of the current investigatiom showed that more than a half of the patients did not get chelation. This might be explained by a variety of factors, including the lack of chelator in some Yemeni facilities and poor compliance among some of the patients under investigation. Because of the exorbitant expense of transfusions and chelating medicines, the situation is dire.
Another research showed that (67%) of the Thalassemia patients they investigated were undergoing some type of chelation treatment. The present study's findings are in conflict with that other study's findings (19).
According to the findings of this study, patients with a pre-transfusion hemoglobin level more than >9 g/dL had substantially higher overall HRQoL ratings than patients with a pre-transfusion hemoglobin level less than <9 g/dL. Because low hemoglobin levels are accompanied with a variety of symptoms such as fatigue, general weakness, and lower mental alertness in addition to other symptoms, this might explain why patients' HRQoL has been found to be compromised (20). Pre-transfusion Hb level should be supervised routinely to retain an optimal level of 9 to 10.5 g/dL(3, 5, 20).
The results of this study also revealed that the regimen of iron chelation therapy was substantially associated with decreased HRQoL. Thalassemia patients who regularly received the iron chelation treatment and patients who occasionally received iron chelation having lower total HRQoL scores when compared with patients not received iron chelation treatment. A repeated course of chelation therapy may result in an increase in iron losses, which may have an indirect effect on the patient's quality of life. Furthermore, patients who did not delay blood transfusion had better total HRQoL scores when compared with patients delay of blood transfusion but there was no considerable association between total HRQoL scores and delay of blood transfusion.
The findings of this study revealed that the lowest domain score in the current investigation was in physical functioning (45.1±18.2), which was not the same as in the previous studies (73.2±14.9) conducted by Mahmoud (12), who explained the high physical functioning score by stating that these patients had low expectations of physical performance because they had been told that they would not be able to perform.
The Jordan study's low HRQoL ratings in the physical domain revealed that their Thalassemia youngsters felt discomfort, pains, and low energy when doing daily activities (16). The discrepancy in HRQoL domain scores can be explained by the fact that the majority of participants in Malaysian research were homozygous beta-Thalassemia and transfusion dependent, whereas the majority of participants in Thailand studies were not and were not transfusion dependent. Furthermore, it was found that there were variations in cultures, experiences, and attitudes across Thailand, Malaysia, and Yemen, which might be explained by a variety of factors. Another investigation found that the mean score of HRQoL among teenagers was more than 70, indicating that they had strong HRQoL, as evidenced by the fact that they considered themselves as physically active and capable of doing their typical daily routine activities. (15). In the majority of the investigations, the subscales of the psychosocial health summary score were used for assessment (3, 5, 16, 21).
Following the findings of the current research, it was discovered that the domain of school functioning had the lowest mean score. In order to maintain their health, children with Thalassemia must get blood transfusions once every three to four weeks at the Thalassemia Day Care Society. Thalassemia patients may experience extra difficulties such as frequent school absences for Thalassemia visits, difficulty coping with schoolwork, and a lack of energy when doing academic tasks. These difficulties can negatively impact the quality of life. However, this conclusion was in contrast to the findings of an Egypt research, which indicated that school functioning ratings improved as a result of the presence of patients who needed to have their blood transfused at the hospital (22).
The current study showed that age and gender had no significant association with physical function. However, this finding is inconsistent with an investigation reported by Sharma et al (2017). They reflected that age of Thalassemia children and gender were associated with physical functioning while it is identical to the investigations conducted by Sazlina et al (2015), Ismail et al (2006) and Thavorncharoen et al (2010) who reported no significant association between gender and physical function. Also, it is similar to some studies done by Ismail et al (2013), Surapolchai et al (2010) and Torcharus et al (2011). They detect no considerable association between age and physical function.
In a study of all factors that influence the physical summary score, it was discovered that the mean yearly serum ferritin level had a non-significant impact on physical health summary score, with greater serum ferritin levels associated with worse physical quality of life scores. This finding is inconsistent with the study done byWasfyet al (2011). This study showed that the type of payment for treatment had not association with physical functioning. According to the findings of one study, patients who were insured by the Universal Health Coverage Scheme had considerably better physical functioning (23).
As regards to clinical factors, the current study showed that emotional functioning was significantly associated with iron over load complications, pre-transfusion Hb level and age at received iron chelation (P-value <0.05) while no significantly associated with types of Thalassemia, age at diagnosis of Thalassemia, family history of Thalassemia, siblings with Thalassemia and serum ferritin level (P-value >0.05).
This finding is inconsistent with the results found by Montarat et al (2010) who reported that iron over load complications, pre-transfusion Hb level and age at received iron chelation, types of Thalassemia. Also, age at diagnosis of Thalassemia, family history of Thalassemia and serum ferritin level were not significant associated with emotional functioning which were consistent with the current study. Also Asrul et al (2020) reported that iron over load complications not significantly associated with emotional functioning. The current studies showed that there was no demographic factors that affect social functioning among Thalassemia patients (P-value >0.05) except place of residency(P-value<0.05). This result was inconsistent with results found by Sazlina et al (2015). There was a statistically considerable relationship between social functioning and both age and educational level. Similarly to the previous study, Thavorncharoensap et al (2010) discovered that age is a major determinant in the development of worse social functioning.
As regards to clinical factors, the current study showed that social functioning was significantly associated with iron over load complications and pre-transfusion Hb level (P-value <0.05) while no significantly associated with types of Thalassemia, age at diagnosis of Thalassemia, family history of Thalassemia and siblings with Thalassemia and serum ferritin level and age at received iron chelation (P-value >0.05). The current study was consistent with the study done by Thavorncharoensap et al (2010) that found pre-transfusion of Hb level was significantly impaired HRQoL in social functioning subscale. They also discovered that patients with anemia who were less than two years old at the time of start and who underwent iron chelation therapy had substantially worse HRQoL in the social functioning subscale. This is in conflict with the findings of the current study.
The current studies showed that there were no demographic factors that affect school functioning among Thalassemia patients (P-value >0.05) except place of residency (P-value <0.05). Basing on an investigation among Malaysian children, school functioning was only associated with age (5).
As regards to clinical factors, the current study showed that school functioning was not significantly associated with any one of clinical factors (P-value >0.05) except for iron over load complications (P-value <0.05). According to the findings of a research conducted among Malaysian children, school functioning was solely related with pre-transfusion hemoglobin levels, and the age at which anaemia first manifested itself was less than two years (5). Aside from that, illness complications were shown to be related with a poor quality of life (16).
It is not feasible to determine if converts in self-rated functioning and well-being would have happened in persons who were not exposed to the same situation because of the study's limitations because there was no control group.
