Muscle enzymes in newly diagnosed hypothyroid patients

Objective: To measure serum levels of CXCL10 and CCL2 prototype chemokines of the two major subclass (CXC and CC) in patients with newly diagnosed chronic autoimmune thyroiditis (AT), and relate the findings to the clinical phenotype. Design and methods: Serum CXCL10 and CCL2 were assayed in 70 consecutive patients with newly diagnosed chronic AT, in sex- and age-matched healthy volunteers (n = 37) and in 20 patients with non-toxic multinodular goiter, extracted from a random sample of the general population from the same geographic area. Results: CXCL10 serum levels were significantly higher in patients with thyroiditis than in controls or multinodular goiter patients, while comparable CCL2 levels were found between groups. CXCL10 levels were significantly increased in hypothyroid patients and in those with an hypoechoic pattern (P = 0.0004 and P = 0.0001, respectively) while serum CCL2 levels were significantly increased in patients older than 50 years and in those with hypothyroidism (P = 0.0001 and P = 0.03, respectively). No correlation between CXCL10 and CCL2 serum levels could be demonstrated. CXCL10 and CCL2 were studied separately in relation to clinical features of AT patients. Two separate multiple linear regression models for CXCL10 and CCL2 were performed, including age, thyroid volume, thyroid stimulating hormone (TSH), FT4, anti-thyroid peroxidase (AbTPO), hypoechoic pattern, and the presence of hypervascularity, demonstrating that ln of serum CXCL10 levels was associated with TSH independently of other possible confounders levels [regression coefficient (R.C.) 0.143 confidence interval (C.I.) (0.042–0.245); P = 0.0059], while serum CCL2 were significantly associated only with age [R.C. 5.412 C.I. (3.838–6.986); P < 0.0001]. Conclusion: Our results, obtained in a large cohort of newly diagnosed AT patients demonstrate increased CXCL10 especially in hypothyroid patients with a more aggressive disorder, and normal CCL2 serum levels in AT.

Hypothyroid Patients

Introduction: Hypothyroidism is due to decreased circulating levels of Thyroid hormones and is caused by inadequate functioning of thyroid gland. Pseudocholinesterase (PCHE) is a nonspecific cholinesterase enzyme that hydrolyses choline based esters in plasma. The purpose of this study was to evaluate the serum level of PCHE in hypothyroid patients. Methodology: The present study was conducted on 100 newly diagnosed hypothyroid patients attending the Medical OPD. The results of patients were compared with 100 healthy controls of either sex of similar age group. Anthropometric measurements, T3, T4, TSH, PCHE & Cholesterol estimations were performed. Results: The mean serum PCHE (decrease) level was observed statistically highly significant (p<0.001) in hypothyroid patients as compared with healthy control subjects. A highly significant positive correlation between PCHE with T3 & T4 (p< 0.001) in hypothyroid cases. Conclusion: Serum Pseudocholinesterase may be helpful as biomarker in screening test for hypothyroidism along with thyroid stimulating hormone.

Introduction: Thyroid hormone effects on many organs including central and peripheral nervous systems. However, these hormones do not affect all systems/organs to a similar extent. Thus, we conducted this study to explore the effect of thyroid hormones on somatic nervous system assessed by Nerve conduction study and cardiac autonomic activity assessed by heart rate variability. Methods: The study included newly diagnosed hypothyroid patients and healthy controls. In all subjects NCS were performed in median, ulnar, tibial and sural nerves using Nihonkohden machine Cardiac autonomic control was assessed using Short-term Heart Rate Variability and parameters were analyzed by Time Domain and Frequency Domain methods. Results: Both the groups were comparable in term of age, Body Mass Index, Pulse Rate, Systolic Blood Pressure and Diastolic Blood Pressure. Sensory parameters of NCS showed significant decrease in left median nerve SNAP amplitude (38.24±10.23 Vs 31.59±14.06, P=0.048) and nerve conduction velocity of bilateral median nerve in hypothyroid patients. In motor parameters of NCS, onset latencies of bilateral median nerves and right ulnar nerve were significantly increased in hypothyroid patients. All Time Domain measures of HRV and Frequency Domain measures; LF Power, HF Power and Total Power were significantly decreased (P<0.05) in hypothyroid patients. These HRV parameters are indicators of parasympathetic activity. Conclusions: In newly diagnosed hypothyroid patients, especially median nerve functions (both sensory and motor) and parasympathetic activity were decreased. It reflects that in hypothyroidism both autonomic nervous system and other somatic nerves are not affected in a similar extent.

Prevalence Of Anemia

Background: The association between anemia and hypothyroidism has been recognized, although the prevalence of anemia in hypothyroid patients varies widely between studies. The main objectives were to study the prevalence, type, etiology of anemia in primary hypothyroidism and to correlate severity of anemia with severity of hypothyroidism.Methods: A case control study was carried out in a tertiary care hospital. Newly diagnosed 60 overt primary hypothyroid patients and 180 euthyroid controls were evaluated for anemia. Morphological types of anemia, their etiology were studied. Severity of anemia was correlated with that of hypothyroidism.Results: Anemia was observed in 45 patients with hypothyroidism. Symptoms due to anemia were significantly higher in cases than in the anemic controls. RBC morphology showed normocytic normochromic in 39, microcytic hypochromic in 14 and macrocytic in 7 cases. Serum iron was significantly lower in the cases than in the controls. Serum anti-TPO positivity was 63.33% in cases as compared to 10% in controls. Anemia was severe in cases with high TSH.Conclusions: The prevalence of anemia was 75% which was higher than that seen in the euthyroid controls. Hypothyroid patients were more symptomatic for anemia than the controls. Normocytic normochromic type of anemia was the most common type in our study. Autoimmunity in the form of anti-TPO positivity was detected in 69% of anemic cases. Iron deficiency was observed in the cases more than in the controls. There was a statistically significant negative correlation between TSH and hemoglobin.

Hypothyroid Patients

Objective: This observational study was conducted during the year 2016–2017 to assess the electrodiagnostic evidence of peripheral nerve dysfunction among newly diagnosed hypothyroid patients attending a tertiary care hospital and to find the effect of hormonal treatment after short duration. Methods: An observational study was conducted in 25 newly diagnosed hypothyroid patients with the age group of 20–60 were included. After obtaining informed consent, all participants were examined with electrodiagnostic workup performed at the initial time of diagnosis and after short duration for median and ulnar nerves of upper limb by (NeuroStim -NS2, EMG/EP/NCV, and MEDICAID SYSTEMS). Electrophysiological parameters such as distal motor latency, amplitude, and conduction velocity were evaluated. Results: The mean age of study population was 42.7±12.1 (23–61) years. The mean values of nerve conduction velocity of motor and sensory median before the treatment were 42.8±15.7 and 40.13±4.19 and motor and sensory ulnar before treatment were 41.18±22.4 and 39.46±11.9. The mean values of nerve conduction velocity of motor and sensory median after treatment were 53.35±4.7 and 57.3±5.6 and motor and sensory ulnar After treatment were 54.56±2.99 and 54.09±12.17. The result of the study. Shows that there were reduction of conduction velocity before treatment and statistically significant after 3 months duration of treatment with appropriate doses. Conclusion: After treatment, total triiodothyronine, total thyroxin, free triiodothyronine, free thyroxin, thyroid-stimulating hormone, and median and ulnar nerve motor and sensory functions were normal with appropriate treatment. The involvement of sensory fibers is more than that of the motor fibers.
