<title>Introduction</title>
<p>Sir&#x0101;granthi results from vitiated v&#x0101;ta in sir&#x0101;s, leading to granthi due to V&#x0101;taprakopaka nid&#x0101;nas. &#x0100;c&#x0101;rya Vagbhata recommends sir&#x0101;vyadha for treating sir&#x0101;granthi. The role of inflammation in vascular diseases is explored, with a focus on Interleukin-6 as a key biomarker. The absence of studies on sir&#x0101;vyadha&#x2019;s impact on inflammatory biomarkers, particularly Interleukin-6, underscores the study&#x2019;s relevance, aiming to observe changes in inflammatory response in varicose veins post-sir&#x0101;vyadha within a 15-day period.</p>
</sec>
<sec id="sec2">
<title>Objective</title>
<p>To observe changes in IL-6 values before and after sir&#x0101;vyadha within a 15-day period in individuals with varicose veins. Materials and Methods: After excluding deep vein thrombosis (DVT) through lower limb color doppler, five subjects who satisfied the inclusion criteria were selected. Assessments included BT, CT, Hb screening, and parameters like AVVQ, pain, edema, tortuosity, skin pigmentation, and itching. Sir&#x0101;vyadha was performed over the tortuous vein with an 18G needle, and sample was collected from drained blood for IL-6 testing. After a 15-day follow-up, Sir&#x0101;vyadha was repeated, and assessment of all parameters were done.</p>
</sec>
<sec id="sec3">
<title>Results</title>
<p>Statistically significant differences (<italic>p</italic>&#x003C;0.05) were observed after treatment in Interleukin-6, AVVQ, pain, edema, tortuosity, and skin pigmentation. However, itching showed no statistically significant difference after treatment (<italic>p</italic>&#x202F;&#x003E;&#x202F;0.05).</p>
</sec>
<sec id="sec4">
<title>Conclusion</title>
<p>In all 5 cases, a reduction in the rate of IL-6 was observed. Remarkably, three patients with initially high values showed a statistically significant reduction (<italic>p</italic>&#x202F;&#x003C;&#x202F;0.05) after sir&#x0101;vyadha treatment, indicating a reduction in inflammation. Clinical and statistical significance (<italic>p</italic>&#x202F;&#x003C;&#x202F;0.05) were also observed in subjective parameters such as pain, edema, tortuosity, and skin pigmentation. Although itching decreased in patients, it did not reach statistical significance, possibly due to some patients not experiencing itching before the procedure. The study demonstrates that sir&#x0101;vyadha effectively reduces the inflammatory response and subjective symptoms of varicose veins. Furthermore, the improvement in the quality of life after sir&#x0101;vyadha was highly significant (<italic>p</italic>&#x202F;&#x003C;&#x202F;0.05). Overall, the study supports sir&#x0101;vyadha&#x2019;s efficacy in reducing inflammatory biomarker IL-6 and subjective symptoms in varicose veins.</p>

<title>Introduction</title>
<p>Due to <italic>v&#x0101;ta prakopaka nid&#x0101;nas</italic> (factors aggravating <italic>v&#x0101;ta</italic>&#x2014;one of the tridoshas that facilitates movement throughout the body), the vitiated <italic>v&#x0101;ta do&#x1E63;a</italic> enters the <italic>sir&#x0101;s</italic> (veins), causing <italic>samp&#x012B;&#x1E0D;ana</italic> (squeezing), <italic>sa&#x1E45;koca</italic> (contraction/cramp), and <italic>vi&#x015B;o&#x1E63;a&#x1E47;a</italic> (act of drying up). This produces a round and protruded <italic>granthi</italic> (knot) in the <italic>sir&#x0101;s</italic> (veins), manifesting as <italic>Sir&#x0101;granthi</italic> (<xref ref-type="bibr" rid="ref1">1</xref>) (a condition correlated with varicose veins (VVs) in Ayurveda). The accumulation of <italic>rakta</italic> (blood) and vitiation of <italic>v&#x0101;ta</italic> (the bodily humor facilitating movement throughout the body) in the <italic>sir&#x0101;</italic> (vein) leads to dilation of veins and tortuosity (<xref ref-type="bibr" rid="ref2">2</xref>). <italic>Rakta</italic> is considered the fourth <italic>do&#x1E63;a</italic> by <italic>&#x0101;c&#x0101;rya Su&#x015B;ruta</italic>. <italic>Raktamok&#x1E63;a</italic> (venesection/bloodletting) is regarded as the ultimate treatment for vascular diseases, especially when <italic>rakta</italic> (blood) and <italic>pitta</italic> (one of the tridoshas that controls heat, metabolism, and transformation of both body and mind) are vitiated. It is considered <italic>ardhacikits&#x0101;</italic> (half of the treatment) in <italic>&#x015A;alyatantra</italic> (the branch of Ayurveda that deals with surgical and para-surgical procedures), similar to how <italic>Vasti</italic> (therapeutic enema) is viewed in <italic>K&#x0101;yacikits&#x0101;</italic> (<xref ref-type="bibr" rid="ref3">3</xref>) (the first branch of <italic>Ashtanga Ayurveda</italic> that deals with general medicine, where <italic>K&#x0101;ya</italic> means body and <italic>cikits&#x0101;</italic> means treatment)<italic>. &#x0101;c&#x0101;rya Vagbhata</italic> recommends <italic>sir&#x0101;vyadha</italic> (venesection/bloodletting) in the <italic>cikits&#x0101; sutra</italic> (line of management) for <italic>sir&#x0101;granthi</italic> (<xref ref-type="bibr" rid="ref4">4</xref>). The effectiveness of siravyadha has already been demonstrated in numerous studies, indicating a positive response to siragranthi by doing siravyadha (<xref ref-type="bibr" rid="ref5 ref6 ref7 ref8">5&#x2013;8</xref>).</p>
<p>Different <italic>lak&#x1E63;a&#x1E47;a</italic>s (signs/symptoms) based on <italic>do&#x1E63;anus&#x0101;ra rakta du&#x1E63;&#x1E6D;i</italic> (vitiation of blood due to each bodily humor) are discussed in classical texts, emphasizing the varied presentations of symptoms. Similarly, variation in the consistency and flow of blood is explained. The role of inflammation in vascular diseases was explored, with a focus on Interleukin-6 as a key biomarker (<xref ref-type="bibr" rid="ref9">9</xref>). IL-6 was found to play a major role in the formation of inflammation. IL-6 is considered to be a surrogate endpoint for varicose veins.</p>
<p>Furthermore, numerous studies support the elevation of IL-6 levels in varicose veins. One study showed that some blood constituents were elevated in varicose vein blood compared to blood from the antecubital vein of the same patient with VVs. The levels of hsCRP, IL-6, vWF, and D-dimer were significantly raised (<xref ref-type="bibr" rid="ref10">10</xref>). Another study investigated the levels of 12 inflammatory cytokines to discover which ones are most important in chronic venous insufficiency (CVI). The results showed that the most relevant inflammatory biomarkers in CVI are IL-6, IL-8, and MCP-1 (<xref ref-type="bibr" rid="ref11">11</xref>). Another study correlated blood constituents in varicose veins with those in the antecubital vein. Blood withdrawn from the site of a varicose vein was found to have significantly increased concentrations of IL-6, fibrinogen, and hemoglobin when compared to the same patient&#x2019;s antecubital blood sample (<xref ref-type="bibr" rid="ref9">9</xref>).</p>
<p>The lack of studies on the impact of <italic>sir&#x0101;vyadha&#x2019;</italic>s (venesection/bloodletting) on inflammatory biomarkers, particularly Interleukin-6, underscores the study&#x2019;s relevance. Therefore, this study aims to observe changes in the inflammatory response in patients with varicose veins post-<italic>sir&#x0101;vyadha</italic> (venesection/bloodletting) over a 15-day period. In addition to IL-6, clinical outcomes were measured using the Aberdeen Varicose Vein Questionnaire (AVVQ) to assess quality of life (QOL) and the visual analogue scale (VAS) to assess pain, edema, tortuosity, skin pigmentation, and itching.</p>

<title>Data recording</title>
<p>Patients were screened by checking for normal values of bleeding time, clotting time, and hemoglobin. Data collection was performed by recording case details using a case report form and questionnaires. The diagnostic criteria included patients with lower limb varicose veins classified as C2, C3, or C4a according to the CEAP classification, who had undergone color Doppler of the lowerlimbs, which suggested the presence of varicose veins and who showed no evidence of DVT. Patients were recruited only after meeting all the above criteria and providing their consent to participate in the study. After recruitment, a procedure visit was advised, and <italic>sir&#x0101;vyadha</italic> was performed with proper <italic>p&#x016B;rvakarma</italic> and <italic>pa&#x015B;c&#x0101;t karma.</italic> Subjective parameters were assessed before the first <italic>sir&#x0101;vyadha</italic> and after the second <italic>sir&#x0101;vyadha.</italic> Blood samples for analyzing IL-6 were collected from the drained blood during both <italic>sir&#x0101;vyadha</italic> procedures.</p>
</sec>
<sec id="sec10">
<title>Study design</title>
<p>The study design was a single-group observational study.</p>
</sec>
<sec id="sec11">
<title>Procedure of <italic>Sir&#x0101;vyadha</italic> (venesection/bloodletting)</title>
<p>The procedure of <italic>Sir&#x0101;vyadha</italic> was performed in two sittings with an interval of 15&#x202F;days in between. The procedure is briefly explained under three titles: <italic>P&#x016B;rvakarma</italic> (preoperative procedure), <italic>Pradhana karma</italic> (main procedure), and <italic>Pa&#x015B;c&#x0101;t karma</italic> (postoperative procedure).</p>
<sec id="sec12">
<title><italic>P&#x016B;rvakarma</italic> (preoperative procedure)</title>
<p>The following materials were collected prior to the procedure: Gauze pieces, swabs, bandages, tourniquet, kidney tray, ounce glass, beaker, needle no.18G, spirit, chair, and dressing table. The patient was given snigdha yavagu (unctuous gruel: gruel added to an adequate amount of ghee) half an hour before the procedure. <italic>Sth&#x0101;nika abhyanga</italic> (localized oil massage) and <italic>n&#x0101;&#x1E0D;&#x012B; sweda</italic> (fomentation) were performed just before <italic>sir&#x0101;vyadha</italic>.</p>
</sec>
<sec id="sec13">
<title><italic>Pradh&#x0101;na karma</italic> (procedure)</title>
<p>The procedure was performed in the morning for each patient. The patient was made to stand comfortably. The leg to be punctured was observed, and a tourniquet was tied above the selected vein. The most tortuous vein was selected and punctured with an 18G needle, and the blood was collected using a kidney tray. The blood was allowed to flow until it stopped by itself. No measures were taken to forcefully stop the flow of the blood. The collected blood was carefully observed. Later, the output was measured using a glass beaker. Standard antiseptic and precautionary measures were taken during the procedure.</p>
</sec>
<sec id="sec14">
<title><italic>Pa&#x015B;c&#x0101;t karma</italic> (postoperative procedure)</title>
<p>As the procedure neared completion, the flow of the blood decreased and finally ceased; after which the needle was withdrawn. The pricked part was cleaned up with cotton swabs, and a tight bandage was applied. The patients were provided with milk for consumption and advised to rest by raising their legs using a pillow. General pathya apathyas (what to follow and what to avoid) were suggested to all patients after the procedure of siravyadha.</p>
</sec>
<sec id="sec15">
<title>Protocol of testing Interleukin-6</title>
<p>Once blood started ejecting from the needle, a sample was collected directly into a test tube, which was coated with EDTA to inhibit coagulation and separate the plasma. The sample was then centrifuged in the hospital laboratory. The quantitative immunoassay ECLIA (electrochemiluminescence) method was used for measuring IL-6. It was performed using a Cobas E601 analyzer (Roche Diagnostics). The comparison method (Milenia Biotec) was a semiquantitative lateral flow immunoassay coupled with a digital image capture system (PicoScan). The total imprecision of the results ranged from 3.7 to 8.0%, depending on the IL-6 concentrations. The unit of Interleukin-6 is picogram/milliliter, abbreviated as pg/mL.</p>

<title>Results on Interleukin-6</title>
<p>A paired <italic>t</italic>-test was performed to evaluate the significant difference in the mean value of Interleukin-6 before treatment and after treatment. Among the recruited patients, samples for checking IL-6 were collected from the blood drained during <italic>sir&#x0101;vyadha</italic>. The blood sample collected on the 1st day was considered the before value, represented as IL-6 BT, and the sample collected on the 15th day was considered the after value, represented as IL-6 AT. IL-6 was found to be in the normal range in the sample analyzed during the first sitting itself in two patients. In the other three patients, elevated levels of IL-6 were observed in the sample analyzed during the first sitting, suggesting severe inflammation. Only those three patients were included in the statistical analysis. It was observed that there was a significant difference in the mean values before and after treatment in the patients with abnormal IL-6 levels. The mean IL-6 score before treatment was 115.26, which decreased to 92.0 after treatment, as shown in <xref ref-type="table" rid="tab3">Table 3</xref>.</p>

<title>Discussion</title>
<sec id="sec24">
<title>Discussion on observations</title>
<sec id="sec25">
<title>Age</title>
<p>The prevalence of varicose veins varies geographically. Currently, it is reported that approximately 2&#x2013;73% of the global population is affected by varicose veins (<xref ref-type="bibr" rid="ref13">13</xref>). In this study, 80% of the patients were aged between 41 and 50&#x202F;years, while the remaining 20% were in the age range of 51&#x2013;60&#x202F;years.</p>
</sec>
<sec id="sec26">
<title>Sex</title>
<p>Of the total patients recruited for the study, four were female and one was male. This predisposition of female individuals to develop varicose veins could be due to the effects of the hormones estrogen and progesterone. All the female patients in the study were parous. In female individuals, key events are directly related to the appearance of varicose veins, such as pregnancy and menopause, which are influenced by age and hormones (<xref ref-type="bibr" rid="ref14">14</xref>). A total of three patients in the study had attained menopause, and one had undergone a hysterectomy 12&#x202F;years prior. Varicose veins in women around menopause show a two-fold increase in the number of ER+ cells and estrogen receptor (ER) gene expression (<xref ref-type="bibr" rid="ref15">15</xref>).</p>
</sec>
<sec id="sec27">
<title>Occupation</title>
<p>It was observed that 60% of the patients recruited for the study had active and long-standing jobs. Among them, 20% had jobs involving frequent travel, and another 20% had jobs requiring prolonged sitting. House makers are required to spend a good amount of time standing. This, in turn, makes them a potential candidate for developing varicose veins.</p>
</sec>
<sec id="sec28">
<title>Discussion on the quantity of blood drained</title>
<p>The procedure was performed in two sittings. The quantity of blood drained was different for each patient. Blood was drained till it stopped on its own. When <italic>sir&#x0101;vyadha</italic> is performed properly, the vitiated <italic>rakta</italic> flows in a stream and it stops naturally without any external hindrance (<xref ref-type="bibr" rid="ref16">16</xref>). The quantity of blood drained from the recruited patients was collected in two sittings, with a 15-day interval between them. The mean volume of blood drained during the first sitting was 159.6&#x202F;mL, while during the second sitting, it was 198&#x202F;mL.</p>
</sec>
<sec id="sec29">
<title>Discussion on the duration of bleeding</title>
<p>The minimum duration of bleeding was 7&#x202F;min, and the maximum duration was 15&#x202F;min. For the first and second patients, the duration of bleeding remained the same in both sittings, and for the third and fifth patients, the duration of bleeding in the second sitting was longer than in the first sitting. For the fourth patient, the duration of bleeding in the second sitting was less than in the first sitting.</p>
</sec>
<sec id="sec30">
<title>Discussion on IL-6</title>
<p>A marked reduction in the values of the inflammatory marker IL-6 was observed for all five patients. IL-6 was found to be within the normal range in the samples analyzed during the first sitting in two patients. However, they exhibited symptoms such as tortuosity, pain, edema, and skin pigmentation, which may be due to some mechanical causes. Their symptoms may not be due to inflammation, since their IL-6 value was normal even before treatment. In the other three patients, elevated IL-6 levels were observed in the samples analyzed during the first sitting, suggesting severe inflammation. These levels were significantly reduced after treatment. Therefore, we can suggest that sir&#x0101;vyadha helps in the reduction of inflammation.</p>
</sec>
<sec id="sec31">
<title>Discussion on the AVVQ</title>
<p>The Aberdeen Varicose Vein Questionnaire is a disease-specific questionnaire that measures health-related quality of life for patients with varicose veins (<xref ref-type="bibr" rid="ref12">12</xref>). The total score ranges from 0 to 100 points, with 0 indicating the best possible quality of life and 100 indicating the worst. In all five patients, QOL greatly improved after the procedure compared to before.</p>
</sec>
<sec id="sec32">
<title>Discussion on pain</title>
<p>Vitiated v&#x0101;ta is a factor for pain, which enhances the stimulation of the neurotransmitter (substance P), which accumulates in the smooth muscle of blood vessels. V&#x0101;ta nirharana (elimination of deranged vata) along with dushita rakta (impure blood) contributes to pain relief after raktamok&#x1E63;ana (bloodletting) (<xref ref-type="bibr" rid="ref6">6</xref>). Resulting from venous hypertension, there is stretching of the veins, which causes pain. The pain in varicose veins increases proportionally with the exertion of legs, indicating that the pain is generally due to v&#x0101;ta do&#x1E63;a. The VAS was used for the assessment of pain, and grading was performed according to the scale. All five patients experienced pain. A marked reduction was observed after treatment, and it was also statistically significant.</p>
</sec>
<sec id="sec33">
<title>Discussion on Edema</title>
<p>Edema may occur due to venous outlet obstruction. This increases venous capillary hydrostatic pressure, leading to the accumulation of tissue fluid. <italic>Raktamok&#x1E63;ana</italic> helps in the reduction of venous hydrostatic pressure and the accumulated tissue fluid, thereby causing a reduction in ankle edema. The effect is better appreciated through <italic>Siravyadha</italic> as it facilitates the drainage of fluid from the interstitial tissues (<xref ref-type="bibr" rid="ref17">17</xref>).</p>
</sec>
<sec id="sec34">
<title>Discussion on tortuosity</title>
<p>Tortuosity was present in all five patients. Self-graded scores were used for the assessment. It reduced after treatment in four patients in this study, which may be due to the regaining of normal elasticity through external punctures and the expulsion of stagnant blood (<xref ref-type="bibr" rid="ref7">7</xref>).</p>
</sec>
<sec id="sec35">
<title>Discussion on skin pigmentation</title>
<p>Brownish pigmentation of the skin over the lower limb was observed in four patients. Self-graded scores were used for the assessment, and grades reduced markedly after treatment in all four patients and were statistically significant. This condition may be caused by hemosiderin deposition resulting from the disintegration of RBCs that have leaked from thin-walled veins. Through the process of raktamok&#x1E63;ana (bloodletting), dead RBCs, along with iron in the form of hemosiderin, are removed. Histamine is stimulated to deposit at the site of RBC extravasation and breakdown in the lower leg, resulting in vasodilation and decreased vascular permeability. This leads to itching and may eventually contribute to the formation of eczema.</p>
<p>Skin pigmentation may be due to the formation of a fibrin cuff that blocks the tiny capillaries. Due to this, there is an increase in venous capillary pressure, leading to its rupture. The stagnant blood gets deoxygenated, leading to brownish depigmentation of the skin. Raktamok&#x1E63;ana (bloodletting) helps eliminate impure blood and reduces venous congestion.</p>
</sec>
<sec id="sec36">
<title>Discussion on itching</title>
<p>Itching is basically considered a kaphaja symptom. Siravyadha is performed for raktaja and paittika conditions. Among the recruited patients, itching over the lower limb was present in three patients, and its grade was reduced significantly after treatment. Itching was absent in the other two patients. The skin becomes dry and flaky due to edema and fibrinogen deposits. This leads to pruritus and scratching, with excoriation and eczematous changes (<xref ref-type="bibr" rid="ref18">18</xref>).</p>
</sec>
<sec id="sec37">
<title>Discussion on the probable mode of action of <italic>Sir&#x0101;vyadha</italic> in <italic>Sir&#x0101;granthi</italic></title>
<p>It was observed that the predominant <italic>do&#x1E63;as</italic> in dushtarakta were <italic>kapha</italic> and <italic>v&#x0101;ta</italic>. The color of blood was blackish-red in all patients during the first sitting, which changed to bright red in most of them during the second sitting. The consistency of blood was thick in most of the patients during the first sitting of <italic>sir&#x0101;vyadha</italic>, which became less thick during the second sitting. Frothy blood was observed in most of the patients during the first sitting of <italic>sir&#x0101;vyadha</italic>, but it was absent or partially relieved in all patients afterwards. This suggests that <italic>sir&#x0101;vyadha</italic> aids in the removal of <italic>du&#x1E63;&#x1E6D;a rakta</italic> and <italic>sanga</italic> (obstruction) within the vessel walls, thereby improving blood flow and promoting the formation of <italic>&#x015B;uddha rakta</italic>. Through <italic>sir&#x0101;vyadha,</italic> in the case of <italic>sir&#x0101;granthi, dushita rakta,</italic> along with <italic>prakupita do&#x1E63;as</italic>, flows out, leading to normal <italic>gati</italic> of <italic>v&#x0101;yu.</italic> This may enhance the circulation of fresh blood, thereby promoting the regeneration of healthy tissues (<xref ref-type="bibr" rid="ref19">19</xref>). <italic>Sir&#x0101;vyadha</italic> acts predominantly on disorders related to <italic>pitta, rakta,</italic> and <italic>kaphaja vy&#x0101;dhi</italic>, or when <italic>pitta</italic> and <italic>kapha</italic> are in association with <italic>v&#x0101;ta do&#x1E63;a</italic>. In conditions where there is <italic>v&#x0101;ta prakopa,</italic> along with <italic>&#x0101;</italic>var<italic>ana</italic> of <italic>kapha</italic> and <italic>pitta, sir&#x0101;vyadha</italic> helps eliminate the <italic>&#x0100;varana</italic> of <italic>kapha</italic> and pitta and facilitates <italic>anulomana</italic> (normal downward movement) indirectly. This ultimately cures <italic>v&#x0100;tika</italic> symptoms along with those of <italic>pitta</italic> or <italic>kapha do&#x1E63;a</italic>, thereby providing patients with instant relief from pain. According to the modern point of view, stimulation of large sensory fibers by peripheral tactile receptors inhibits the transmission of pain signals either from the same area of the body or from many segments. This results in local lateral inhibition. Interleukin-6 is considered a surrogate endpoint of the varicose vein, but <italic>siravyadha</italic> is a treatment modality mentioned for <italic>siragranthi</italic>. In this study, the patients with a normal IL-6 value still exhibited symptoms of <italic>siragranthi,</italic> and <italic>siravyadha</italic> led to a remarkable decrease in those symptoms. Therefore, <italic>Sir&#x0101;vyadha</italic> not only alleviates the symptoms of <italic>siragranthi</italic> but also reduces elevated inflammatory biomarker IL-6 levels.</p>
</sec>

<sec sec-type="conclusions" id="sec38">
<title>Conclusion</title>
<p>In all five cases, a reduction in the value of IL-6 was observed. Remarkably, three patients with initially elevated values showed a statistically significant reduction (<italic>p</italic>&#x202F;&#x003C;&#x202F;0.05) after the <italic>sir&#x0101;vyadha</italic> treatment, indicating a reduction in inflammation. Clinical and statistical significances (<italic>p</italic>&#x202F;&#x003C;&#x202F;0.05) were also observed in the subjective parameters such as pain, edema, tortuosity, and skin pigmentation. Although itching decreased in the patients, it did not reach statistical significance, possibly due to some patients not experiencing itching before the procedure. The study demonstrates that <italic>sir&#x0101;vyadha</italic> effectively reduces the inflammatory response and the subjective symptoms of varicose veins. Furthermore, the improvement in the quality of life after <italic>sir&#x0101;vyadha</italic> was highly significant (<italic>p</italic>&#x202F;&#x003C;&#x202F;0.05).</p>
</sec>
<sec id="sec39">
<title>Strengths</title>
<p>There was an overall improvement in symptoms among all five recruited patients, with a significant enhancement in their quality of life. Inflammatory biomarker IL-6 levels were markedly reduced in the patients. <italic>Sir&#x0101;vyadha</italic> helped alleviate inflammatory symptoms. Although the IL-6 levels were within the normal range in two patients, <italic>sir&#x0101;vyadha</italic> helped maintain these levels even after the procedure. The subjective parameters, including QOL, were greatly improved in all patients. As an observational study, all areas were carefully noted, observed, and documented.</p>
</sec>
<sec id="sec40">
<title>Limitations</title>
<p>The small sample size limits the ability to draw generalized conclusions. Therefore, a larger sample would be necessary to validate the findings. The wide variation observed in the before-treatment values of IL-6 can be considered a limitation of the study. In addition, due to the very small sample size, there is a constraint in extrapolating the reliability. However, the same may be carried out only in patients with abnormal/raised IL-6 values.</p>
