Rheumatoid Arthritis: Risk factors and potential treatments 
José Eduardo Ramos Miranda 
University of Puerto Rico at Cayey, Cayey, Puerto Rico, Department of Natural Sciences 
Abstract: 
This paper reviews the disease of rheumatoid arthritis(RA) and how finding its causes are so 
important for the prevention of this autoimmune disease. Throughout the years this disease has 
been in our lives, affecting mainly the adult population, and narrowing it down to female patients. 
Specifically, we can see how different institutes of health try to determine possible diagnoses and 
causes for this disease. Treatment and rehabilitation are important for the control of this disease. 
RA is a chronic disease, meaning its effects keep increasing over time. But luckily we have 
treatments that slow down this process and makes coping with RA easier. Methrotexate (MTX) is 
highlighted throughout this paper because of the amount of people who are using it recently. At 
the end, suggested research that is being worked on is presented to enlighten the conscience of 
these patients

Conclusion 
Introduction 
Rheumatoid arthritis (RA) is a complex disease affecting approximately 0.5% of the adult 
population worldwide, and it occurs in 20-50 cases per 100,000 annually. It strikes mainly women 
in their 40s or older (Carmona et al. 2010). Its origin remains elusive, but there is evidence that 
both genetic and environmental factors trigger the pathogenesis. Growing evidence suggests that 
RA consists of at least 2 different subsets characterized by the presence or absence of antibodies to 
citrullinated protein antigen (ACPA) (Svendsen et al. 2013). RA is located in all areas of the world 
in which the prevalence rates for females tend to be higher than the rate for males. Medline Plus 
(2014), states that this specific form of arthritis causes pain, swelling, stiffness, and loss of 
function in your joints such as wrist and fingers. RA is an autoimmune disease that mistakenly 
attacks healthy cells in your body. In addition, there is no proven cause of why autoimmune 
diseases appear. The author states that there are more than 80 types of autoimmune diseases, and 
some are very similar, nevertheless the main goal in treating these diseases is to reduce the 
inflammation. Anyone can get this disease even though there is no proven cause. Gaujoux et al. 
(2014) say that this disease runs a chronic course marked by flares of synovial membrane 
inflammation that can eventually cause joint destruction, thereby compromising quality of life and 
causing disability.
Sometimes we can ask ourselves, how is it diagnosed? Well even though this disease can be hard 
to diagnose because its symptoms take time to really develop. Common diagnoses include: 
medical history, physical exams, x rays, and lab tests. Carmona et al. (2010) describes the 
emphasis is now on early intervention with the aim of preventing disability and irreversible 
damage, resulting in a race to find the earliest point in time to treat the disease safety. RA has 
different name varieties in which it is diagnosed: early RA, undifferentiated RA, and advanced 
RA. We can deduce that even because RA is very present in our everyday lives and it is virtually 
impossible to fight; there is still an option to keep finding a plausible cause or solution to this 
overwhelming disease. 
Risks factors of RA 
When it comes to relevant risks factors for the occurrence of the condition, Carmona et al. (2010) 
states many factors in the pathogenesis of this disease. First, RA involves multiple genes, but 
genes with the major histo-compatability complex appear to have the strongest influence on the 
susceptibility of the disease. The major histo-compatability complex is a group of genes that code 
for proteins that are situated in the surface of the cells. Also, this complex works with the immune 
system, targeting foreign substances. Even though the concept of susceptibility factors is still 
being researched, we can assume that factors like this one certainly have a huge effect on what is 
going on with this disease. Secondly, Carmona et al. (2010) reports that a significantly increased 
risk of RA has been demonstrated in women whose pregnancies were complicated by hypermesis, 
gestational hypertension, or pre-clampsia. Hypermesis is a disorder that causes the pregnant 
woman to suffer from nausea, vomiting, weight loss and even electrolyte deduction. Meanwhile, 
pre-clampsia is another disorder that affects the blood pressure of the patient and the high 
concentration of protein in the urine. The author gives certain sex-related associations that go in 
relation with the mother having a higher susceptibility than the man. This is very alarming because 
this segment of the population is the most delicate, due to the dangers related to the different 
stages of child birth. The third factor that the authors mention is general lifestyle factors. Habits 
like smoking are etiological factors because they show a clear interaction with genetic 
susceptibility genes. Infections also play a part on this disease; Epstein-Barr virus, parvovirus, and 
bacteria like Proteus and Mycoplasma. These factors are very important because they can serve as 
warning signs to patients who have symptoms or are suffering from this disease. Carmona et al. 
(2010) suggests that future patients should take into consideration: behavioral factors, climate, 
environmental exposures, RA diagnosis and genetic factors. 
Potential Remedies or Treatments 
The optimal management of patients with RA requires a dialogue between the rheumatologist and 
patient to ensure that the patient receives the information and education needed to share in his or 
her management decisions (Gaujoux et al. 2014). Thanks to advances in science we can say that 
RA can be treated, even though this is a chronic disease. The main goals are to: take away pain, 
reduce swelling, slow down or stop joint damage, help people feel better, and stay active. These 
main goals are given by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. 
Treatments can and may involve lifestyle changes, medicine, surgery, regular doctor visits and 
alternative therapies. One main factor that affects the variation between treatments is the state of 
the patient. Some people may have an advanced type of disease while other patients may still be in
the early stages. This makes it necessary have a diverse array of options when it comes to the 
quantity or type of treatment for RA, or in any type of autoimmune disease. Gaujoux et al. (2014) 
proposes a three-phase treatment plan: this algorithm starts with Phase I, and the treatment 
strategies for recent-onset of RA. After the diagnosos of RA there is an initiation of MTX, 
combined with short-term glucocorticoid therapy, plus an initiation of sulfasalazine or 
leflunomide. After a waiting period or three to six months we can determine to continue the 
treatment or go to Phase II. The second phase consists on treatment strategies for RA with an 
inadequate response to methotrexate, starting off by using add-on biologic (anti-TNF or abatacept 
or tocilizumab or rituximab), and if there is failure switch to other DMAR LEF, SSZ, MTX alone 
or combined. After the stipulated waiting period you can continue the treatment or go to the final 
phase. The final and third phase is a treatment strategy in RA with an inadequate response to 
biologic therapy. The patient has the option to switch to a second anti-TNF or abatacept or 
tocilizumab or rituximab in case that the treatment doesn’t seem effective. The method is very 
useful when helping patients with very different needs when it comes to treatments. 
Methrotrexate 
The use of immunosuppressive agents in the treatment of rheumatoid arthritis began in the 1950s 
after the introduction of NSAIDs and corticosteroids (Cripriani et al. 2014). Later, other drugs that 
are from the same ladder, were introduced and formed a very important part in this line of 
treatment for the patient. Among the disease-modifying antirheumatic drugs, MTX 
(methrotrexate) is currently considered the “anchor drug” for the treatment of RA; it is 
administered in up to 70% of patients with this disease (Cipriani et al. 2014). This is an alarming 
and essential detail. The rheumatologist is the specialist who should be in charge of managing 
patients with RA (Gaujoux et al. 2014). For over 50 years this antimetabolite drug has established 
itself as effective to many autoimmune disorders that have been developed over the years. 
Cripriani et al. (2014) studied available research in relation to (MTX) and how it is useful for RA 
patients. They pointed to the importance of MTX and the routes of oral, subcutaneous, and 
intramuscular administration. The importance of the oral MTX route was highlighted throughout 
the study. However, the main reason parenteral (injected) administration of this drug is 
recommended is because of the patient’s poor compliance with taking the oral dosage. The authors 
provided good and helpful information on whether to consider the oral administration of MTX, or 
parenteral administration, keeping in mind that both are beneficial to the quality of life of the 
patient with RA. Secondly, the dosage and quantity of MTX was also considered a factor in terms 
of the direct effect of the drug. Cipriani et al (2014) informs us that MTX acts specifically during 
the synthesis of RNA and DNA in the S phase of the cell cycle. Also, the author reports that many 
studies have pointed out to the long-term efficacy and safety of MTX. This drug is a great choice 
for the first-line of treatment for a recent onset of RA, and as a consequence, it improves the 
overall response of the patient’s disease. 
Conclusion 
There is a suggestion that the incidence and severity of RA may have declined over the past few 
decades. This decline has been attributed to the trend to ‘invert the pyramid and to diagnose and 
treat rheumatoid disease earlier and more aggressively (Carmona et al. 2010). The author also 
mentions that the pattern of use of treatments, with earlier aggressive treatment and the 
introduction of new drug therapies, is a more than plausible cause for the new found decline. The
aggressiveness factor from this article may have a point when it comes to an overall projection on 
what is the immediate future for RA. When it comes to treatments, the use of MTX is highly 
recommended because of so many testimonies of active patients taking the drug. Cipriani et al. 
(2014) suggest that OR-MTX should be initiated at the highest tolerable dose, with a progressive 
weekly increase of the drug to the maximal recommended dosage and an early witch to the 
parental route in case of unresponsiveness or evidence of adverse effects, before switching to 
another drug. We may not have a clear idea of the exact causes of this disease, but at least we have 
advances on different treatments that can slow down this chronic and devastating illness. 
Nevertheless we must have in consideration that by knowing more of these high risk factors, we 
can introduce at a much higher lever drugs and natural remedies that stop the disease effects. 
Further research is being done now in many areas like: immune systems, genes, families with 
rheumatoid arthritis, new drugs or drug combinations, rheumatoid arthritis and disability, 
preventing related health problems, and quality of life for people with rheumatoid arthritis. All of 
these routes are being explored for the sake of our physical well-being.

Review Paper

  • 1. Rheumatoid Arthritis: Risk factors and potential treatments José Eduardo Ramos Miranda University of Puerto Rico at Cayey, Cayey, Puerto Rico, Department of Natural Sciences Abstract: This paper reviews the disease of rheumatoid arthritis(RA) and how finding its causes are so important for the prevention of this autoimmune disease. Throughout the years this disease has been in our lives, affecting mainly the adult population, and narrowing it down to female patients. Specifically, we can see how different institutes of health try to determine possible diagnoses and causes for this disease. Treatment and rehabilitation are important for the control of this disease. RA is a chronic disease, meaning its effects keep increasing over time. But luckily we have treatments that slow down this process and makes coping with RA easier. Methrotexate (MTX) is highlighted throughout this paper because of the amount of people who are using it recently. At the end, suggested research that is being worked on is presented to enlighten the conscience of these patients Table of Contents: Introduction Origin of rheumatoid arthritis and autoimmune diseases Diagnosis Rheumatoid Arthritis description Risks factors of rheumatoid arthritis Potential remedies or reatments Metrotexate Conclusion Introduction Rheumatoid arthritis (RA) is a complex disease affecting approximately 0.5% of the adult population worldwide, and it occurs in 20-50 cases per 100,000 annually. It strikes mainly women in their 40s or older (Carmona et al. 2010). Its origin remains elusive, but there is evidence that both genetic and environmental factors trigger the pathogenesis. Growing evidence suggests that RA consists of at least 2 different subsets characterized by the presence or absence of antibodies to citrullinated protein antigen (ACPA) (Svendsen et al. 2013). RA is located in all areas of the world in which the prevalence rates for females tend to be higher than the rate for males. Medline Plus (2014), states that this specific form of arthritis causes pain, swelling, stiffness, and loss of function in your joints such as wrist and fingers. RA is an autoimmune disease that mistakenly attacks healthy cells in your body. In addition, there is no proven cause of why autoimmune diseases appear. The author states that there are more than 80 types of autoimmune diseases, and some are very similar, nevertheless the main goal in treating these diseases is to reduce the inflammation. Anyone can get this disease even though there is no proven cause. Gaujoux et al. (2014) say that this disease runs a chronic course marked by flares of synovial membrane inflammation that can eventually cause joint destruction, thereby compromising quality of life and causing disability.
  • 2. Sometimes we can ask ourselves, how is it diagnosed? Well even though this disease can be hard to diagnose because its symptoms take time to really develop. Common diagnoses include: medical history, physical exams, x rays, and lab tests. Carmona et al. (2010) describes the emphasis is now on early intervention with the aim of preventing disability and irreversible damage, resulting in a race to find the earliest point in time to treat the disease safety. RA has different name varieties in which it is diagnosed: early RA, undifferentiated RA, and advanced RA. We can deduce that even because RA is very present in our everyday lives and it is virtually impossible to fight; there is still an option to keep finding a plausible cause or solution to this overwhelming disease. Risks factors of RA When it comes to relevant risks factors for the occurrence of the condition, Carmona et al. (2010) states many factors in the pathogenesis of this disease. First, RA involves multiple genes, but genes with the major histo-compatability complex appear to have the strongest influence on the susceptibility of the disease. The major histo-compatability complex is a group of genes that code for proteins that are situated in the surface of the cells. Also, this complex works with the immune system, targeting foreign substances. Even though the concept of susceptibility factors is still being researched, we can assume that factors like this one certainly have a huge effect on what is going on with this disease. Secondly, Carmona et al. (2010) reports that a significantly increased risk of RA has been demonstrated in women whose pregnancies were complicated by hypermesis, gestational hypertension, or pre-clampsia. Hypermesis is a disorder that causes the pregnant woman to suffer from nausea, vomiting, weight loss and even electrolyte deduction. Meanwhile, pre-clampsia is another disorder that affects the blood pressure of the patient and the high concentration of protein in the urine. The author gives certain sex-related associations that go in relation with the mother having a higher susceptibility than the man. This is very alarming because this segment of the population is the most delicate, due to the dangers related to the different stages of child birth. The third factor that the authors mention is general lifestyle factors. Habits like smoking are etiological factors because they show a clear interaction with genetic susceptibility genes. Infections also play a part on this disease; Epstein-Barr virus, parvovirus, and bacteria like Proteus and Mycoplasma. These factors are very important because they can serve as warning signs to patients who have symptoms or are suffering from this disease. Carmona et al. (2010) suggests that future patients should take into consideration: behavioral factors, climate, environmental exposures, RA diagnosis and genetic factors. Potential Remedies or Treatments The optimal management of patients with RA requires a dialogue between the rheumatologist and patient to ensure that the patient receives the information and education needed to share in his or her management decisions (Gaujoux et al. 2014). Thanks to advances in science we can say that RA can be treated, even though this is a chronic disease. The main goals are to: take away pain, reduce swelling, slow down or stop joint damage, help people feel better, and stay active. These main goals are given by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Treatments can and may involve lifestyle changes, medicine, surgery, regular doctor visits and alternative therapies. One main factor that affects the variation between treatments is the state of the patient. Some people may have an advanced type of disease while other patients may still be in
  • 3. the early stages. This makes it necessary have a diverse array of options when it comes to the quantity or type of treatment for RA, or in any type of autoimmune disease. Gaujoux et al. (2014) proposes a three-phase treatment plan: this algorithm starts with Phase I, and the treatment strategies for recent-onset of RA. After the diagnosos of RA there is an initiation of MTX, combined with short-term glucocorticoid therapy, plus an initiation of sulfasalazine or leflunomide. After a waiting period or three to six months we can determine to continue the treatment or go to Phase II. The second phase consists on treatment strategies for RA with an inadequate response to methotrexate, starting off by using add-on biologic (anti-TNF or abatacept or tocilizumab or rituximab), and if there is failure switch to other DMAR LEF, SSZ, MTX alone or combined. After the stipulated waiting period you can continue the treatment or go to the final phase. The final and third phase is a treatment strategy in RA with an inadequate response to biologic therapy. The patient has the option to switch to a second anti-TNF or abatacept or tocilizumab or rituximab in case that the treatment doesn’t seem effective. The method is very useful when helping patients with very different needs when it comes to treatments. Methrotrexate The use of immunosuppressive agents in the treatment of rheumatoid arthritis began in the 1950s after the introduction of NSAIDs and corticosteroids (Cripriani et al. 2014). Later, other drugs that are from the same ladder, were introduced and formed a very important part in this line of treatment for the patient. Among the disease-modifying antirheumatic drugs, MTX (methrotrexate) is currently considered the “anchor drug” for the treatment of RA; it is administered in up to 70% of patients with this disease (Cipriani et al. 2014). This is an alarming and essential detail. The rheumatologist is the specialist who should be in charge of managing patients with RA (Gaujoux et al. 2014). For over 50 years this antimetabolite drug has established itself as effective to many autoimmune disorders that have been developed over the years. Cripriani et al. (2014) studied available research in relation to (MTX) and how it is useful for RA patients. They pointed to the importance of MTX and the routes of oral, subcutaneous, and intramuscular administration. The importance of the oral MTX route was highlighted throughout the study. However, the main reason parenteral (injected) administration of this drug is recommended is because of the patient’s poor compliance with taking the oral dosage. The authors provided good and helpful information on whether to consider the oral administration of MTX, or parenteral administration, keeping in mind that both are beneficial to the quality of life of the patient with RA. Secondly, the dosage and quantity of MTX was also considered a factor in terms of the direct effect of the drug. Cipriani et al (2014) informs us that MTX acts specifically during the synthesis of RNA and DNA in the S phase of the cell cycle. Also, the author reports that many studies have pointed out to the long-term efficacy and safety of MTX. This drug is a great choice for the first-line of treatment for a recent onset of RA, and as a consequence, it improves the overall response of the patient’s disease. Conclusion There is a suggestion that the incidence and severity of RA may have declined over the past few decades. This decline has been attributed to the trend to ‘invert the pyramid and to diagnose and treat rheumatoid disease earlier and more aggressively (Carmona et al. 2010). The author also mentions that the pattern of use of treatments, with earlier aggressive treatment and the introduction of new drug therapies, is a more than plausible cause for the new found decline. The
  • 4. aggressiveness factor from this article may have a point when it comes to an overall projection on what is the immediate future for RA. When it comes to treatments, the use of MTX is highly recommended because of so many testimonies of active patients taking the drug. Cipriani et al. (2014) suggest that OR-MTX should be initiated at the highest tolerable dose, with a progressive weekly increase of the drug to the maximal recommended dosage and an early witch to the parental route in case of unresponsiveness or evidence of adverse effects, before switching to another drug. We may not have a clear idea of the exact causes of this disease, but at least we have advances on different treatments that can slow down this chronic and devastating illness. Nevertheless we must have in consideration that by knowing more of these high risk factors, we can introduce at a much higher lever drugs and natural remedies that stop the disease effects. Further research is being done now in many areas like: immune systems, genes, families with rheumatoid arthritis, new drugs or drug combinations, rheumatoid arthritis and disability, preventing related health problems, and quality of life for people with rheumatoid arthritis. All of these routes are being explored for the sake of our physical well-being. Cited Literature: 1. Carmona L, Cross M, Williams B, Lassere M, March Lyn. 2010. Rheumatoid arthritis.
