Background Psoriasis is a prevalent inflammatory skin disease. Psoriasis is a complex illness in which environmental variables acting on individuals with unique genetic predisposition causing immunological dysregulation. Claudins are transmembrane proteins that help to generate tight junctions by binding to the actin cytoskeleton. Claudin 3 in the blood is thought to be a good indicator of intestinal permeability. Objective: The aim of this study was to detect of the alteration of claudin-3 in psoriasis patient and find the correlation between severity and concentration of the claudin-3. Patients and methods: forty psoriatic patients (25males and 15 females) and thirty normal healthy controls (19 men and 11 females) who were age and sex matched to the cases group were included in this study. They were chosen at random from Al Fallujah hospital Dermatology Department outpatient clinic. Result: When compared to the control group, the psoriasis group had substantially greater levels of claudin-3 (mean=2.18 ± 0.16 versus 1.27 ± 0.03; p0.0001). Furthermore, the amount of claudin-3 rose progressively as the severity grade increased (001). There were no significant correlations between claudin-3 levels and gender, dietary status, or family history in the psoriasis group (p>0.05 for each). Conclusion: Claudin-3 levels were considerably greater in psoriasis patients than in healthy controls. PASI levels were shown to be linked to claudin-3 levels.

Abstract Background: Previous studies suggested that alterations in serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. Imbalance in serum cortisol and DHEA-S levels may be related to responsivity to antipsychotic treatment. Aim: To compare serum cortisol and DHEA-S levels between patients with schizophrenia and healthy controls and to evaluate their association with psychopathology in schizophrenic patients with different response to antipsychotic treatment. Material and Methods: This clinical prospective study included 60 patients with schizophrenia and 40 healthy age and sex matched controls. All patients experienced an acute exacerbation of the illness (PANSS: P1 and P3 ≥ 4). Clinical evaluation of patients was performed using the Positive and Negative Symptom Scale. A questionnaire for socio-demographic and clinical data collection was used. For the purposes of the study, the examined group was divided in two subgroups: responders and nonresponders. Serum cortisol and DHEA-S levels were measuredat baseline in all participants and after 3 and 6 weeks of the antipsychotic treatment in patients with schizophrenia. Results: Patients with schizophrenia had significantly higher serum cortisol and DHEA-S levels comparedwith control group. Responders had significantly higher serum cortisol and DHEA-S levels compared with nonresponders. Responders group had significant correlation between serum cortisol and PANSS positive scale score as well as between hostility and serum DHEA-S. Conclusion: Elevated serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. Serum cortisol and DHEA-S are associated with psychopathology in schizophrenic patients with different response to antipsychotic therapy.

Objective Patients with acromegaly are at increased risk of colorectal polyps. However, their risk of colorectal cancer remains unclear. This study aimed to identify the histopathological features of colorectal polyps in patients with acromegaly and compare their risk of colorectal cancer with that in healthy controls. Methods The study participants were 178 patients who underwent Hardy’s operation and perioperative colonoscopy at our hospital between April 2008 and September 2016. For the control group, we randomly selected 356 age- and sex-matched patients who underwent colonoscopy at our hospital during the same period. The incidence, size, location, and histology of the colorectal polyps detected were compared between the groups. Results Colorectal polyps were detected in 66.8% of the acromegaly group and 24.2% of the control group (P < 0.001). The average number and size of the polyps were 2.44 and 4.74 mm, respectively, in the acromegaly group and 1.77 and 3.89 mm in the control group (P = 0.001). Polyps in the acromegaly group were more likely to be in the rectosigmoid region (P = 0.006). In the acromegaly group, the frequency of polyps ≥5 mm was 34.3% and that for polyps ≥10 mm was 15.2%; the respective values were 7.6% and 2.2% in the control group (P < 0.001). We found no evidence of between-group histopathological differences in the polyp specimens resected by endoscopy. ConclusionsPatients with acromegaly are at an increased risk of colorectal polyps, especially in the rectosigmoid region. However, there is no pathological evidence that they are at greater risk of colorectal cancer than the general population.

Purpose: To investigate platelet-to-lymphocyte ratio (PLR) in retinal vein occlusion (RVO) patients. Methods: In this study, we retrospectively reviewed data of 32 patients with RVO (RVO group) and 32 age- and sex-matched participants without RVO (control group) between January 2017 and March 2019. The PLR was determined by dividing the platelet count by the lymphocyte count. Results: Age and gender were comparable between the groups ( p = 0.204 and p = 0.800, respectively). PLR was significantly elevated in the RVO group compared with the control group (137 (113–164) vs 101 (86–129), p = 0.001)). In the receiver operator characteristics curve analysis, the optimal cut-off value of PLR for predicting RVO was 123, with 69% sensitivity and 72% specificity. Conclusion: We report that PLR are elevated in RVO, suggesting that PLR may be a useful marker for RVO.

Abstract Background B-Thalassemia, sickle cell disease (SCD) and other inherited hemoglobin disorders are considered the most prevalent monogenic diseases worldwide. Secondary iron overload is one of the major complications in such groups of patients affecting many organs (e.g. liver, heart and endocrinal glands). Objective The current study will assess brain iron content ( using R2* values ) in the caudate and thalamic regions through quantitative brain MRI study in B-Thalassemia and SCD patients in comparison to age and sex-matched healthy controls. Also evaluation of the association with LIC (liver iron concentrations) and MIC (myocardial iron concentrations) was done. Methods A case control study on 30 patients (15 with B-thalassemia major and 15 with SCD) and 11 age and sex-matched healthy controls was carried out in the period between August 2018 till August 2019. Brain MRI study using multiecho fast gradient echo sequence was done for all the patients and controls. Brain R2* values of both caudate and thalamic regions (right and left sides) were calculated. Also brain R2* values were correlated with the LIC and HIC in B-thalassemia and SCD groups. Results 15 transfusion dependent B-thalassemia (mean-age: 19.40 ± 4.31 years, 53.3% females), 15 SCD patients (SCD; mean-age: 16.93 ± 3.41 years, 40.6% females) and 11 age and sex matched healthy controls (HC; mean age: 18.73 ± 4.84 years, 54.5% females) were enrolled in the study. No statistically significant differences were found between SCD and control group in all regions of interests No statistically significant differences were found between the three subgroups (p &gt; 0.05) in right thalamus, left and right caudate regions. However, in B-thalassemia subgroup, patients had moderately significantly higher R2* values compared to the controls and SCD patients as regards the left thalamic region with mean R2* values (16.69 ± 1.34) Hz compared to (15.65 ± 1.10) Hz in the control group (p = 0.021) and (15.79 ± 0.77) Hz in the SCD group (p = 0.029). There were no significant correlations between LIC and HIC with brain R2* values of all regions of interests in both B-thalassemia and SCD subgroups. Conclusion MRI is a valuable, reliable, safe and noninvasive method for quantifying iron concentration (in cases of iron overload) in many organs as the liver and heart and it is now used internationally for regular follow up of LIC and HIC for monitoring of the chelation therapy in B-thalassemia and SCD patients. The results of our study showed that even in cases of iron overload which affects vital organs as the liver, cardiac and brain iron overload don't occur. This may be explained by heavy chelation therapy regimens given to our patients due to their poor compliance so as to keep the pre-transfusion hemoglobin level above 10mg/dl to prevent detrimental cardiac affection as cardiac siderosis, arrhythmias including heart block, or even heart failure.

Purpose. In this study, we evaluated corneal epithelial integrity and tear film parameters in patients with inflamed pinguecula and compared these findings with their fellow eyes and with healthy controls. Methods. We evaluated the fluorescein staining properties and performed the tear break-up time (TBUT) test and Schirmer 2 test (ST2) measurements of 32 patients who had symptomatic unilateral inflamed pinguecula and compared the results with their fellow eyes and also with an age- and sex-matched control group. Results. Twenty-three eyes (72%) in the inflamed pinguecula group and 1 eye (3.1%) in the fellow eyes group had punctate epithelial staining (PES) or epithelial defect on the nasal cornea (p<0.001). There was no PES or epithelial defect in the control group. Eyes with inflamed pinguecula (n = 32) had lower TBUT and ST2 values compared to the control group (n = 32) (p<0.001 for both). Fellow eyes (n = 32) also had lower TBUT and ST2 values compared to the control group (p=0.003 for both). There was no difference in the TBUT and ST2 results between the eyes with inflamed pinguecula and fellow eyes (p=0.286 and p=0.951, respectively). Conclusion. A high percentage of eyes with inflamed pinguecula had nasal corneal epithelial staining or epithelial defect. We also found lower TBUT and ST2 results in eyes with inflamed pinguecula and the fellow eyes compared to the control group. These findings may be important in pathogenesis of pinguecula and pterygium and also in uncovering their relation.

Aim. To assess the parameters of local immune response in patients with different forms of allergic rhinitis, associated with nasal bacterial infection. Methods. Nasal swabs and nasal epithelium samples obtained from 10 patients with seasonal allergic rhinitis aged 12 to 32 years and from 15 patients with persistent allergic rhinitis aged 18 to 45 years, as well as form the 20 healthy subjects aged 18 to 45 years without signs of allergy who were age and gender-comparable, were examined. Swabs were prepared from cell suspension, stained with 0.04% trypan blue solution, and a microscopy with the count of non-stained cells was performed. Epitheliocytes expressing toll-like receptors-2, were determined by flow cytometry. Interleukin-10 concentration in swabs was assessed by ELISA. Results. The number of epitheliocytes expressing toll-like receptors-2 was by 1.9 times lower in patients with seasonal allergic rhinitis and by 1.7 times lower in patients with persistent allergic rhinitis compared to control group. There was a reverse correlation found between the number of epitheliocytes expressing toll-like receptors-2 and interleukin-10 level in nasal swabs of healthy controls, while in patients with allergic rhinitis a it was a direct correlation. In patients with persistent allergic rhinitis S. aureus was a part of microbiota in 100% of cases and was associated with other bacteria (Str. pyogenes - 33.3%, Neisseria spp. - 66.7%). In patients with seasonal allergic rhinitis the association of S. aureus and S. hemolyticus (70.0%) was the most frequent one. In the control group, S. epidermidis (50.0%), Str. viridians (25.0%), S. hominis (25.0%) were among the nasal microbiota. There were no differences revealed between the mean levels of interleukin-10 in patients with allergic rhinitis and healthy controls. Conclusion. The number of epitheliocytes expressing toll-like receptors-2 was significantly reduced by almost 2 times in patients with persistent allergic rhinitis compared to control group. Colonization of nasal mucosa by S. aureus in patients with allergic rhinitis leads to an increase of epithelial cells expressing toll-like receptors-2.

Abstract Background/Objectives: This study was designed to investigate serum protein levels in acne patients.Method: Acne patients (n=362) and healthy volunteers (n=272) were matched in terms of both age and sex. Serum levels were measured.Results: Among the 362 acne patients and 272 age- and sex-matched healthy controls, serum albumin levels in female acne patients were lower than in the healthy controls (P < 0.05), serum albumin levels in male acne patients were lower than in the healthy controls (P < 0.01). Additionally, serum globulin and total protein levels were significantly lower in acne patients than in the healthy control group (P < 0.01). Serum levels of prealbumin were significantly lower in female acne patients than in the control group (P < 0.05). Finally, the severity of female and male acne patients was negatively correlated with serum total protein, albumin, globulin, and prealbumin levels. Conclusions: The results of this study suggested that acne patients are potentially accompanied with protein malnutrition.

Background: Bipolar affective disorder is an episodic illness characterized by fluctuating mood states. Association of dermatoglyphic traits with bipolar affective disorder has been observed in various studies. This study was undertaken to evaluate epidermal ridge patterns in bipolar patients as compared to healthy controls attending a super speciality district hospital in West Bengal. Context and purpose of study: Establishing dermatoglyphic parameters as biomarkers for early diagnosis and consequently, prompt intervention in bipolar affective disorder will ensure a greater scope of recovery, and thus promote a better quality of life for the individual as well as lower the burden of disease for the society. Methods: Quantitative dermatoglyphic parameters namely, Total Finger Ridge Count (TFRC), Total A-B Ridge Count (TABRC), and ATD Angle of 100 bipolar patients were compared to 100 age and gender matched healthy controls. Results: Statistically significant differences were found on comparing the dermatoglyphic parameters between cases and controls. TFRC was found to be decreased while ATD angle was increased in bipolar cases, as compared to the control group. However, no significant change was observed in TABRC between the two groups. Conclusions: This study found a significant association between dermatoglyphic pattern anomalies and the development of bipolarity. This may offer a scope of primordial prevention of bipolar disorder in future. Key words: Dermatoglyphics, ridge pattern, bipolar disorder, Total Finger Ridge Count (TFRC), Total A-B Ridge Count (TABRC), ATD angle.

Abstract Background and Aims Telomere length (TL) is an emerging novel biomarker of ageing and survival. Telomere shortening to a critical limit is associated with replicative senescence and cell death; a process accelerated by oxidative stress and chronic inflammation. This process is often observed among patients with end stage kidney disease (ESKD). This predisposes them to increased morbidity and mortality in comparison to their normal counterparts when matched for age and gender. The exact reason for premature ageing in this cohort remains poorly understood and there is a need for further investigations into biomarkers of ageing to help understand the process. The aim of the study was to investigate if patients with ESKD in comparison to healthy controls had an increased biological age based on telomere length measurements. Method This was a single centre prospective, observational, cohort study among eligible dialysis patients and healthy controls. The healthy control group consisted of potential living donors. Patients were recruited as per the study protocol. Recruited patients on HD had their blood sampled prior to their mid-week dialysis session while potential live donors and PD patients had their blood sampled at outpatient clinics. Whole blood was immediately isolated for peripheral blood mononuclear cells (PBMC). Genomic DNA was extracted from PBMC to measure relative telomere length (rTL) by quantitative real-time polymerase chain reaction according to the modified Cawthon protocol. Baseline demographic data and 1-year mortality were obtained from electronic patient records. Results A total of 336 patients (125 patients on HD, 114 patients on PD and 100 healthy controls) had their baseline rTL measured between the period of December 2015 to July 2018. Inter assay CV for rTL assay was 4.86%. Mean age of the dialysis cohort was 54.3 with an age range between 23-83 years. Mean age of control cohort was 44.5 with an age range between 20-75years. There were 87 and 56 females in the dialysis and control cohort respectively. Age was significantly associated with TL in a multivariate regression model in both the dialysis (p&lt;0.001) and control group (p&lt;0.001). There was no significant difference in mean TL between gender in the healthy cohort in our study p=0.778. However, mean TL was higher in females than in males among dialysis patients, p=0.007. Mean TL of control and dialysis group was 2.23 ± 0.33 and 2.11 ± 0.34 respectively. The difference in TL between the groups was significant, p=0.006. However, a multivariate analysis of TL adjusted for age and gender was not significant, p=0.875. This was due to the control cohort consisting of younger recruits in comparison to the dialysis cohort. TL was not significantly different between HD and PD patients. There were 10 deaths in 365 days with no loss of follow up throughout the study period. All the deaths were in the dialysis cohort. There was no significant association found between TL and mortality outcomes but the direction of effect i.e shorter TL was associated with increased risk of death. Conclusion This study failed to show any difference between TL between dialysis patients and controls to demonstrate that patients on dialysis age faster. This does not preclude current evidence suggesting that dialysis patients do have an accelerated ageing in comparison to healthy cohort but merely that our study has shown that TL may not be the ideal biomarker of ageing to demonstrate this difference. In fact, increasing animal studies have found that the rate of change in TL over a period of time is a better representation of ageing. The study also identified no association between TL and 1-year mortality as there were only 10 deaths within the 1 year of follow up. This may be largely due to a short duration of follow up and it may be interesting to evaluate TL and 5-year mortality data in this cohort in future.

We determined the serum concentration of biotin, zinc, antiepileptic drugs, and biotinidase enzyme activity in 20 children treated with valproic acid, in 10 children treated with carbamazepine, and in 75 age- and sex-matched healthy controls. There were no significant differences in the serum levels of biotin, and biotinidase enzyme activity between the patients treated with valproic acid, the patients treated with carbamazepine, and the control group. Zinc serum levels were lower in the patients treated with valproic acid and with carbamazepine than in the control group, but within the normal range. Hair loss was observed in 3 patients treated with valproic acid, with normal serum levels of biotin, zinc, and biotinidase activity, and the alopecia disappeared with the oral administration of biotin (10 mg/d) in 3 months. These results suggest that the treatment with valproic acid does not alter the serum levels of biotin, zinc, and biotinidase enzyme activity.
