Abstract Background and Aims Todays increasing effort are made to detect non-invasive and reliable methods for prediction of organ rejection. In the current study, we evaluated the degree of CD3, CD20, Th17 and Tregs infiltration in kidney biopsy of the patients with acute cellular rejection and the possible relation with graft outcome. Method From 70 biopsy proven ATCMR according to Banff criteria in whom kidney biopsy were done based on acute creatinine rise, 50 patients were selected. 20 patients excluded because of insufficient specimen or clinical data. All of recruited patients experienced their first episode of ATCMR. 21 patients had deceased donors and 29 had living ones. Paraffin sections were deparaffinized then dehydrated using alcohols. The tissues were incubated with Antibodies in two stages. First, they were incubated with antihuman IL-17 monoclonal antibody and polyclonal antibody against FOXP3. The results analyzed with SPSS version 20. P value less than 0.05 was considered as significant. Results FOXP3 mean cell count in stable graft function group was 7.88 but in impaired graft group was 8.02, which was not statistically significant (P-value :0. 96). Th17 mean cell count in stable group was 5.0 but in impaired group was 10.1, which was not significant too (P-value: 0.24). FOXP3/Th17 ratio was higher in stable group (1.4 versus 1.12) but without any statistically important value (P-value: 0.22) .CD3 count was higher in impaired group (29.8 versus 27.7) and CD20 count was more in stable group (8.8 versus 7.8) without any significant values (P-value: 0.7 and 0.62) respectively. FOXP3 positive cell count was higher in failure to response group (9.95 vs. 6.63) but with non-significant P-value of 0.1. Th17 count was higher also in this group (11.3 vs. 8.3) but with non-significant value .The FOXP3/Th17 ratio was higher in appropriate response group (1.19 vs. 1.15) with P-value 0.8 .CD3 count was higher in response group and CD20 in failure group vice versa (31.2 vs. 27.3 and 7.96 vs. 8.06) also with nonsignificant values Conclusion We observed that allografts with higher Th17 at biopsy had lower levels of GFR in the next 12 months. One conclusion can be that assessing the Th17 infiltration is more effective than FOXP3 Tregs in predicting the prognosis of renal transplant .

Abstract Background and Aims Renal transplantation is considered as the best replacement therapy for advanced ESRD patients. An allograft rejection happens as a result of post transplant immune reactions, which change the outcome of the organ transplantation. Today a major challenge in the field of transplantation is the identification of easy, reliable and non-invasive markers or methods that being able to predict the probability of organ rejection. One of the possible methods is looking for type of infiltrated cells in tissue obtaining by biopsy stained with specific cellular markers and assesses the infiltration of these cells in different types of rejection. Here the severity of CD3, CD20, Th17 and FOXP3 infiltration in patients with biopsy proven acute cellular rejection was evaluated based on IHC staining, whether these specific infiltrations can show an association with graft outcome or not. Method 50 patients with biopsy proven Acute T Cell Mediated Rejection (ATCMR) recruited. Previous clinical data and 1 year clinical follow up collected. The entire specimen assessed for infiltration of CD3, CD20, FOXP3 Tregs and Th17 with IHC. Patients divided into subgroups: stable graft function versus impaired graft function based on serum creatinine course in one year follow up after rejection therapy and appropriate response to treatment versus failure to response, based on allograft function throughout the course of admission. Results In impaired graft function arm, FOXP3 (7.88 vs. 8.02 with P-value 0.96) and Th17 cells were higher (5.01 vs. 10.2 with P-value 0.24) but with non-significant values. FOXP3/Th17 ratio was higher in stable group (1.4 vs. 1.12 with P-value 0.22). In failure to response to therapy group both FOXP3 (9.95 vs. 6.63 with P-value 0.1) and Th17 (11.3 vs. 8.3 with P-value 0.15) cells were higher. FOXP3/Th17 ratio was higher in proper response group (1.19 vs. 1.15 with P-value 0.8). No significant difference was obtained between CD3 and CD20 infiltration in these two groups. Conclusion Final results showed that Th17 has more important role in predicting the graft outcome and response to treatment and FOXP3 infiltration had a minor part. This may be in controversial with previous facts about the role of FOXP3 cells, which drive the allograft into stable condition.

Introduction: A large number of Human Immunodeficiency Virus (HIV) infected patients are taking combination Antiretroviral Therapy (cART) worldwide as it has led to dramatic improvements in them with a decreased viral load as well as an increase in Cluster of Differentiation (CD4+) T cell count. Though the incidence of HIV associated Chronic Kidney Disease (CKD) has decreased with the use of effective cART, the prevalence of End Stage Renal Disease (ESRD) in HIV positive patients has increased due to the risen longevity owing to them. Aim: To study the renal function abnormalities in HIV infected patients and to compare the change in renal function of treatment naïve patients with patients on triple drug regimen (cART). Materials and Methods: This prospective longitudinal cohort study was conducted on 54 Enzyme Linked Immunosorbent Assay (ELISA) positive HIV patients belonging to the age group of 18-70 years of both the genders over a period of two years from August 2017 to September 2019 in MKCG Medical College and Hospital, Berhampur, Odisha, India. Forty nine HIV infected patients naive to cART and five patients on cART for a minimum period of three months were included in this study. All patients were treated with triple therapy regimens of either ZLN (Zidovudine 300 mg+Lamivudine 150 mg+Nevirapine 200 mg) or TLE (Tenofovir 300 mg+Lamivudine 150+Efavirenz 600 mg) daily; in a single dose at bed time. Renal function parameters like serum urea, serum creatinine, Creatinine Clearance (CrCl), estimated Glomerular Filtration Rate (eGFR) and CD4+ T cell count of treatment naive patients were compared with the same patients on cART after six months duration. GFR was calculated by Modification of Diet in Renal Disease (MDRD) equation. Results were analysed using the Statistical Package for the Social Sciences (SPSS) software for Windows Version 17.0. Results: Out of 54 patients, 53.7% (n=29) were males and 46.3% (n=25) were females. The mean CrCl of HIV positive patients on cART (79.09±25.705 mL/min) was higher than treatment naive (69.65±25.506 mL/min) patients and was highly significant (p-value=0.003). The mean eGFR of HIV positive patients on cART (102.711±26.9424 mL/min/1.73 m2) was higher than treatment naïve (90.189±28.2575 mL/min/1.73 m2) patients and was highly significant (p-value=0.003). The mean serum urea of HIV positive patients on cART (25.78± 4.721 mg/dL) was lower than HIV positive treatment naïve (26.19±4.742 mg/dL) patients but was non-significant (p-value=0.640). The mean serum creatinine of HIV positive patients on cART (0.815±0.1393 mg/dL) was lower than HIV positive treatment naïve patients (0.906±0.1687 mg/dL) and was also highly significant (p-value=0.003). The mean CD4+ T cell count of HIV positive patients on cART (401.63±225.816 cells/μL) was higher than HIV positive treatment naïve (287.13±198.263 cells/μL) patients and was very highly significant (p=0.001). Conclusion: Renal impairment (CrCl <60 mL/min) and eGFR (<60 mL/min/1.73 m2) were higher in HIV positive treatment naive patients than those on cART. Radiological parameters like size of the kidney and cortical echogenicity became normal after six months on cART.

The study of the prevalence of asymptomatic <em>Plasmodium falciparum</em> in humans infected with immunodeficiency virus (HIV) was carried out in Ile-Ife, Osun State Nigeria. The aim of the study is to determine the prevalence of asymptomatic infection <em>P.falciparum</em> in HIV positive individuals and correlate it to age Parasitaemia and CD4 T cell count. Out of ninety three (93) HIV positive patients that participated in the study, 53 (58.8%) were females while 40 (41.4%) were males; 48 (52.4%) females and 35 (33.8%) males were positive for asymptomatic <em>P. falciparum</em> given a total number of 83 (86.6%). Twenty non-HIV patients were used as control samples: 9 (45%) were males and 11 (55%) were females. With 3.0 (33.3%) males and 5 (45.45%) females were positive with insignificant value of mean Parasitaemia of 125.0µl of blood. Age group 31-40 had the highest positive rate of 26 (32.2%) and age group 11-20 and above 60 had the least of positive rate. The correlation between age and both CD4 T cell count and Parasitaemia showed levels of significance less than 0.01 (P&lt;0.01) while the correlation between CD4 T cell and count and Parasitaemia showed no significant correlation, having P-value of P&gt;0.05. Comparing the males mean age, CD4 T cell count and Parasitaemia with that of females there was no level of significance P-value being greater than 0.05 (P&gt;0.05) each. In conclusion, the study showed that in asymptomatic P<em>lasmodium falciparum</em>, almost all the tested samples were positive which could be as a result of depletion in the immune level, hence there is need to always screen for <em>Plasmodium falciparum</em> whether in asymptomatic or symptomatic patients. The CD4 T cells count from the study can not be used for the detection or determination of the presence of malaria infection in HIV positive patients. The best method for malaria identification so far is still the staining method. There should not be discrimination when sampling the patient when investigations on HIV and malaria are to be carried out when both are infected.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease. Few biomarkers for SLE have been validated and widely accepted for the laboratory follow-up of inflammatory activity. In SLE patients, with lupus nephritis (LN), complement activation leads to fluctuation of serum C3 and C4 that are frequently used as clinicalm biomarker of disease activity in SLE. Patients and Methods: In this study the number of patients were 37, seven patients were excluded for incomplete data collection, 28 were females ,2 were males. The duration of the study is two years from 2015 to 2017. Patients were considered to have SLE and LN according to American College of Rheumatology (ACR) criteria, and International Society of Nephrology/ Renal Pathology Society (ISN/RPS). All patients were evaluated withm clinical presentation, laboratory investigations. Our patients underwent kidney biopsy according to standard procedure by Kerstin Amann, and their tissue specimens were studied in the laboratory with light microscope (LM) and immunofluorescence microscope reagents. The relationship between the serological markers and immunofluorescence deposits in kidney biopsy of all patients were studied using the statistical analysis of Pearson correlation and single table student's T test. A P value 0.05 was considered statistically significant. Results: The granular pattern of IF deposits was present in all LN patients, and in more than two third of patients these IF deposits presented in glomerular, tubular, and mesangium sites. While less than one third of patients had IF deposits in the mesangium only. There was no statistically significant correlation between serum ANA, anti-dsDNA, and IF deposits of different types. There was significant correlation between serum C3 and C4 hypocomplementemia and IgG immune deposits in kidney biopsy, and there was significant relationship between serum C3 hypocomplementemia and full house immunofluorescence (FHIF) deposits inm kidney biopsy.Conclusions:Immunofluorescence deposits is mainly granular pattern in LN patients. There was no significant association between serum ANA, anti-dsDNA, and immune deposits in kidney tissue. Immunofluorescence deposits of IgG type correlates significantly with serum C3 and C4 hypocomplemetemia, and these immune deposits in association with low complement levels correlates with LN flare. There was significant correlation between C3 hypocomplementemia and FHIF.

Background: Serum cytokine levels over the course of HIV infection usually increase with immunosuppression and decrease after antiretroviral treatment (ART). Objectives: The aim of the study is to compare cytokine levels between HIV-infected patients (HIP) and controls and investigate the relationship between CD4+T cell count, HIV-RNA levels, and cytokine levels. Methods: The study subjects comprised ART-naive HIP (n=30) with no comorbidities and age-and sex-matched healthy controls. We measured levels of IL-6, IL-1β, TNF-α, and IFN-γ in serum samples of HIP at the beginning and at month 6 of ART and in controls. Results: The mean age of the study subjects was 38.7 ±10.3 years, with men making up 86.7% of the study subjects (n=26). IL-6, IL-1β, and TNF-α levels were significantly higher in both ART-naive (p<0.001, p=0.002, p=0.001) and ART-experienced HIP (p<0.001) than controls. The IFN-γ level was lower in both ART-naive and ART-experienced HIP compared to controls (p=0.082 and p=0.002). There was a positive correlation between the CD4+T cell count and serum concentration of IFN- γ(r=0.320, p<0.05). While the serum IFN-γ concentration showed a negative correlation with the HIVRNA level(r=-0.412, p<0.001), the serum IL-1β, IL-6, and TNF-α concentrations showed a positive correlation with the HIV-RNA level (r=0.349, p<0.001; r:0.54, p<0.001; r:0.438, p<0.00). Conclusions: Although serum concentrations of IL-6, IL-1β and TNF-α showed a significant decrease after ART, they were still significantly higher than the controls. IFN-γ responded differently to ART compared to the other cytokines, indicating that it may play a distinct and important role in the pathogenesis of HIV infection.

Background: Acute pancreatitis is usually a mild and self-limiting disease. About 25 % of patients have severe episode with mortality up to 30%. Early identification of these patients has potential advantages of aggressive treatment at intensive care unit or transfer to higher centre. Several scoring systems are available to predict severity of acute pancreatitis but are cumbersome, take 24 to 48 hours and are dependent on tests that are not universally available. Haematocrit has been used as a predictor of severity of acute pancreatitis but some have doubted its role.Objectives: To study the significance of haematocrit in prediction of severity of acute pancreatitis.Methods: Patients admitted with first episode of acute pancreatitis from February 2014 to July 2014 were included. Haematocrit at admission and 24 hours of admission were compared with severity of acute pancreatitis. Mean, analysis of variance, chi square, pearson correlation and receiver operator characteristic curve were used for statistical analysis.Results: Thirty one patients were included in the study with 16 (51.61%) male and 15 (48.4%) female. Haematocrit at 24 hours of admission was higher in severe acute pancreatitis (P value 0.003). Both haematocrit at admission and at 24 hours had positive correlation with severity of acute pancreatitis (r: 0.387; P value 0.031 and r: 0.584; P value 0.001) respectively.Area under receiver operator characteristic curve for haematocrit at admission and 24 hours were 0.713 (P value 0.175, 95% CI 0.536 - 0.889) and 0.917 (P value 0.008, 95% CI 0.813 – 1.00) respectively.Conclusion: Haematocrit is a simple, cost effective and widely available test and can predict severity of acute pancreatitis.Journal of Kathmandu Medical College, Vol. 4(1) 2015, 3-7

Pneumocystis carinii pneumonia (PCP) is the most frequent opportunistic infection in patients with AIDS, occurring in 80% and recurring in 50% of patients within 12 months of the first episode. Prophylaxis for PCP is recommended if the CD4+ cell count is <200×106/l or 20% of the total lymphocyte count, or after an episode of PCP. The most effective prophylactic agent currently is trimethoprim-sulphamethoxazole and should be the drug of choice but alternatives such as aerosol pentamidine are being increasingly used for patients who cannot tolerate this combination or other oral preparations. If aerosol pentamidine is used and administered via a Respigard II Marquest nebulizer, the dosage should be higher than the currently recommended monthly dosage of 300 mg.
