Ankylosing spondylitis is a chronic rheumatic disease that affects the spine and sacroiliac joints, causing pain and inflammation. We presented a case of a 61 years old male with ankylosing spondylitis that, despite being receiving Nonsteroidal anti-inflammatory drugs (NSAIDs), analgesics and prednisone showed clinical deterioration. The patient received phototherapy within a range from 425 to 650 nm and a cytokine profile was measured at previous to the therapy and after 48 sessions. The clinical improvement was evident with pain remission and mobility recovery, as well as reduction in the proinflammatory cytokine profile.

Ankylosing Spondylitis (AS) is a chronic rheumatic disease that affects the spine and sacroiliac joints, causing pain and inflammation. Its global prevalence is between 0.1 and 1.4%, and patients with active disease may present diminished physical functioning due to the loss of lumbar mobility . Nonsteroidal anti-inflammatory drugs (NSAIDs) and Coxibs remain important therapeutic options for AS, but since the last decade onwards, in developed countries, the use of biologic and synthetic Disease-Modifying AntiRheumatic Drugs (DMARD) and tumour necrosis factor inhibitors (TNFi) has been increased significantly; on the contrary, the use of steroids has been decreased [2–3]. On the other hand, different types of phototherapies, varying widely in the range of nanometers applied, have been used in clinical practice against autoimmune diseases [4–6]. Despite, its well known clinical benefit, there is scarce information regarding non UV phototherapy. In this line, our group has proved the benefit of this therapy against Rheumatoid Arthritis . Looking for cheaper and efficient options against autoimmune diseases, the aim of this paper was to report a case of AS with clinical improvement after phototherapy treatment with the documentation of changes in the cytokine profile.
Male of 61 years
Familial antecedents: The patient’s 83-year-old mother had Chronic Obstructive Pulmonary Disease (COPD) associated with exposure to wood smoke, in addition to Type 2 Diabetes Mellitus (T2DM) and Arterial Hyper Tension (AHT) for 20 years, who had undergone right supracondylar amputation three years ago, with Chronic Renal Failure (CRF) and retinopathy, under medical management. The patient’s father had died 30 years ago at the age of 71 years after underwent a surgery for right kidney tumor. The patient’s three siblings aged 47, 56, and 65 years have T2DM. He has three apparently healthy children aged 32, 30, and 29 years.
Personal non-pathological information: Schooling: 6th grade; Occupation: Employee at the Federal Electricity Company (CFE) from the age of 18 years, working in the maintenance and repair of energized lines. The patient frequently received 150–200 volt electric shocks in the job for 20 years, always working with protective equipment. Smoking denied. Positive alcoholism from the age of 23 until 35 years, with alcohol ingestion once a month, consuming tequila or brandy (100–200 mL). Drug addictions denied. Complete immunization scheme in childhood. Application of influenza vaccine every two years.
Personal pathological data: Uncomplicated measles and childhood infectious diseases. From the age of 18–20 years, repetitive events of sore throat, odynophagia, cough, expectoration, and chills without fever remained up to three weeks, predominating in the period from December to January. Left inguinal hernia after physical activity at the age of 19 years, with no complications. Left wrist fracture at the age of 52 years without complications. Four Urinary Tract Infections (UTI) since the age of 40 years, past from three years, always receiving medical management for up to one and one half months with oral antibiotics not specified by the patient. Allergies and transfusions denied.
Current disease: From May 1994, the patient initiated with the disease at age of 40 years, when he presented intermittent pain in the lumbar region of mild intensity 2–3/10, of daily presentation, from the time of he gets up in the morning. He went to a general practitioner who referred him to second-level medical attention, where he was prescribed naproxen-type medications and other analgesics, which he took continuously, as well as daily physical exercise for rehabilitation purposes. Lumbar pain increased in intensity during the winter season to 5–6/10 with difficulty in bending.
In 2001, cervical pain 5–6/10 was added, with progressive intensity and with difficulty in turning over to the side, which increased until the patient was totally disabled for five years. From 2006, he was required to perform neck movements en bloc. After the onset of cervical pain, his family physician referred him to a Rheumatologist who, after performing laboratory tests including HLA-B27 and X-rays, confirmed the diagnosis of AS. Management was begun with NSAID, analgesics and Prednisone, the patient taking the latter for 3–4 months. Pain increased in the lumbar region to 8/10, which forced the patient to walk in a semi-flexed posture, this was last for a period of one year. Pain intensity subsequently decreased to 3/10, remaining under these conditions until 10 years previously, when the patient stopped taking his medication for apparent remission of pain; the patient felt good, without discomfort. For the past 10 years, the patient has reported paresthesias in the outer half of the fourth finger and of the entire right hand (ulnar affectation), extending to the middle third of the palmar region.
In 2016, patient referred pain in the right shoulder 8/10, right back, and right thorax 6–7/10, right elbow 6/10, which produced severe limitation for mobility of the upper right limb, with the inability to perform personal tasks such as eating or bathing. In addition, there was shoulder and right elbow flogosis with inflammation of the affected back and chest. Since April 7, 2016, the patient received, from a general practitioner, Diclofenac-Cholestyramine 75 mg p.o. every 12 h, thus reducing pain, flushing, and inflammation of the chest and back by about 50%, but after two months, due to physical limitation and pain, the patient was invited to receive phototherapy sessions.
Arterial Blood Pressure (ABP): 122/80; heart rate: 70 x'; respiratory rate: 14 x'; temperature: 36°C, weight: 91 kg; height: 1.73 m; Body Mass Index (BMI): 30.4, and capillary glucose: 125 mg/dL.
The patient experienced painful facies when attempting to mobilize neck and right upper limb, both of these with severe inability to perform minimal movements. Normal brain cerebral functions. Eyes with bilateral pterygium with conjunctival congestion ++, without secretion. Fundoscopy with angiosclerotic angiopathy without alterations in the retina. Neck: severe limitation on attempting lateral as well as flexion and extension movements. Mild jugular engorgement. Thyroid not palpable. Thorax: severe pain on palpation of the infrahumeral region, especially the pectoral musculature, which is perceived on touch with slight induration. Precordial area with rhythmic heart sounds, no blows or gallop. Soft abdomen, depressible, with normoperistalsis without hepatosplenomegaly. Extremities without edema. Joint exploration demonstrated mild-to-moderate spontaneous pain to pressure in the right shoulder with severe functional limitation in its arches of mobility. Mild pain on mobilization of right elbow. Prehension force: right hand: 300 mmHg; left hand: 300 mmHg. Imaging studies revealed cervical column affection (Figure 1), the characteristic “bamboo spine” (Figure 2), and right shoulder lesion (Figure 3).

This intervention was approved by the Ethics Committee of the Maternal-Perinatal Hospital “Monica Pretelini Saenz” (HMPMPS), code: 217B500402017001. Briefly, with the patient in supine position and placing the lamp 30 cm above the neck, the patient received phototherapy within a range from 425–650 nm (visible light spectrum) (Figure 4), 11.33 Joules/cm2 (Phototherapy lamp, Federal Ministry of Health registration number 1694E95). The phototherapy scheme was 30 min, three times a week.

Granulocyte Macrophage Colony Stimulating Factor (GMCSF), Interferon-γ (INF-γ), Interleukin-4 (IL-4), IL-6, IL-10, IL-12, Monocyte Chemotactic and Activating Factor (MCAF), and Tumor Necrosis Factor alpha (TNF-α) (Multiplex Human Cytokine ELISA Kit) were determined with the Optical Density (OD) value method by means of the Enzyme-Linked Immunosorbent Assay (ELISA) at 490 nm employing ELx800™ equipment (BioTek Instruments, Inc., USA). The process was conducted in blinded fashion at the Research Laboratory of CipresGrupoMedico S.C. (CGM), Toluca, State of Mexico, Mexico.
After phototherapy sessions, the patient’s clinical improvement was notorious. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Bath Ankylosing Spondylitis Functional Index (BASFI) showed impressive changes, the first from 100 to 0 points and the second from 98 to 6 after the 48 sessions. The Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) changed from 15 to 1. The latter evaluations happened in addition to the reduction in the inflammatory profile (GM-CSF, MCAF, TNF-α) and vice versa with that of the anti-inflammatory cytokines (IL-4, IL-10). IL-12 was practically without changes (Table 1).

At present, there are several pharmacological alternatives for treating AS. While the first is the use of NSAID, for those patients whose disease activity remains high despite the use of the former, anti-TNF drugs comprise second-line treatment. Other AS therapies include DMARD, such as Hydroxychloroquine, Methotrexate and Sulfasalazine, for patients with peripheral arthritis .
A limiting factor for the generalized use of anti-TNF is the cost, up to US $1,182 per month per patient, of course with price disparities, being the lowest cost associated to the use of Etanercept, followed by Adalimumab and Infliximab . When evaluating the disease activity, inflammation, lumbar pain and physical function, a two year randomized open trial reported no differences between Infliximab and Etanercept therapy . In the case of the treatment that we offered to the patient, no cost to the patient was involved at our Institution. In case of the treatment being installed in the patient’s home, this could cost between US $25 and US $50 per month for a period of one year, adding the cost of the lamp and the electricity consumption.
Inflammation of the sacroiliac joint at the base of the spine, followed by rising inflammation along the spine are the principal features of AS that results in back pain and stiffness . Although the use of NSAID, DMARD, and non-drug interventions such as physical therapy may offer palliation of symptoms, including peripheral joint pain, spinal pain, in addition to the improvement shown in the physical function [12,13], none has been shown to alter the progression of AS. In the case we reported, it was clear the clinical improvement with the phototherapy, the patient recovering the mobility of the lumbar and cervical column. We anticipate that our findings will produce reasonable doubts in the rheumatological field. Thus, the medical patient file and a possible in vivo online contact with the patient and authors are available upon request.
It is certain that targeted biologic therapies have revolutionized the clinical management of AS. In this line, clinical trials have shown that these agents produce clinically important benefits to patients by improving physical functioning and reducing disease activity . A previous meta-analysis synthesized the data on different agents and concluded that TNF-α blockers improve disease activity and functional capacity in AS [15,16]. Based on our previous reports of the effect of phototherapy on autoimmune diseases [7,17], we think that this therapy reduces TNF-α levels by still unknown mechanisms, probably changing the Th1/Th2 lymphocyte ratio.
It is recognized that the action of phototherapy over autoimmune diseases is effective, with several modalities (Table 2). Notwithstanding, we think the feasibility of our technique offers a new opportunity to reach a clinical improvement at low cost.
Table 2: Modalities of phototherapy against autoimmune diseases.
Phototherapy within a range of 425–650 nm was effective in this case of AS for the recovery of mobility and for pain reduction, which offers a new window for exploration and a new, inexpensive alternative for treatment of this disease. The mechanism of action appears to be the reduction of TNF-α levels.
