Frequency and predictors of pulmonary hypertension in patients with Systemic Lupus Erythematosus.

OBJECTIVE: To determine the frequency and predictors of pulmonary hypertension in patients with Systemic Lupus Erythematosus in a Pakistani population, presenting at a tertiary care hospital. METHODS: This cross-sectional study was conducted at the Department of Rheumatology, Shiekh Zayed Hospital, Lahore from March to June 2018. A total of 97 patients, who fulfilled the Systemic Lupus Erythematosus (SLE) criteria of American College of Rheumatology (ACR) 1992 were enrolled. Pulmonary Arterial Hypertension (PAH) was measured by calculating pulmonary arterial systolic pressure through echocardiography by a single consultant cardiologist. Disease characteristics and demography was collected in a self-administered proforma. PAH was defined as mean pulmonary arterial pressure of 25mmHg or above by calculating with a formula. SPSS version 20 was used for analysis of data. RESULTS: Out of 97 patients, 89.7% (n=87) were females and 10.3% (n=10) were males, with mean age of 31.29± 8.824 years. The mean disease duration was 24.21 ± 30.46 months. PAH was found in 23.3% (n=23) patients, including 19 females and 4 males. On further analysis of data, Raynaud phenomenon, rheumatoid factor and nephritis were assessed as predictors of PAH and all of these showed statistical significance for presence of PAH as per Chi-square test (p<0.05). CONCLUSION: In this study, 23.3% SLE patients showed evidence of PAH and positive statistical significance was found between predictors like Raynaud phenomenon, rheumatoid factor, nephritis and presence of PAH. So it is imperative to detect PAH early and start prompt treatment to achieve better quality of life.

Takayasu Arteritis: Pattern Of Clinical And Radiological Features, Experience From Pakistan.

BACKGROUND: Takayasu arteritis (TKA) is a rare large vessel vasculitis occurring in young adults of less than 50 year of age. We analyse the clinical, radiological features, and treatment regimens in Pakistani patients presenting to a tertiary care center. METHODS: A retrospective cross-sectional analysis of TKA patients done at the Rheumatology department of Fatima Memorial Hospital. A comprehensive evaluation of clinical, laboratory, radiographic features and treatment regimens was carried out. RESULTS: A consecutive cohort of 18 patients, with 13 patients (72%) of female gender was studied. Mean age of the cohort was 35.94±2.7 years. A mean delay of 2.32±0.43 years between symptoms and final diagnosis was reported, attributed to alternate diagnosis in 57.1% and late presentation in 42.8% cases. Limb claudication (44.4%), absent pulses (38.9%), were the common initial manifestation. Hypertension (61.5%), blood pressure discrepancy between arms (88.9%) and bruit (72.2%) over major vessels were common systemic features. As per angiographic classification, Type V (44.4%), and Type I (33.3%), were most common pattern of disease in the cohort. Subclavian artery (72.2%), renal artery (33.3%), iliofemoral arteries (27.8%), and coronary artery involvement (16.7%) were the common lesions. Coronary artery lesion was higher in females (p=0.52) while renal artery lesion in males (p=0.27). There was no statistically significant difference in involvement of vessels according to gender (p >0.05). CONCLUSIONS: Type V and Type I are the common pattern of TKA. Limb claudication was the most common initial manifestation. Renal artery involvement was seen more commonly in males while coronary artery involvement more commonly in females.

Stress at Home and Female Gender Are Significantly Associated With Non-adherence and Poor Illness Perception Among Patients With Rheumatoid Arthritis.

Aims We aimed to assess the level of non-adherence and poor illness perception among rheumatoid arthritis (RA) patients. Additionally, we examined their associations with clinical indicators and outcomes. Methods This was a cross-sectional study conducted using data collected at the time of patient enrolment in the Pakistan Registry of Rheumatic Diseases (PRIME) registry. A wide range of clinical variables was studied. To measure adherence, we used the Urdu version of the General Medication Adherence Scale (GMAS), which has recently been validated in RA patients. A Brief Illness Perception Questionnaire (BIPQ) was used to measure illness perception. Results The data of consecutive 320 RA patients were reviewed. Thirty-six percent of the cohort (n=116) was noted to have non-adherence. On multiple logistic regression analysis, a significant association of non-adherence was noted with moderate-to-severe stress (odds ratio {OR}: 1.85, confidence interval {CI}: 1.04-3.2), DAS-28 scores (OR: 1.83, CI: 1.52-2.21), Health Assessment Questionnaire (HAQ) scores (OR: 1.77, CI: 1.07-2.92), and deformed joint counts (OR: 1.30, CI: 1.15-1.46). Additionally, non-adherence due to "patient behavior" had a significant association with the male gender (OR: 0.48, CI: 0.26-0.87), unemployment (OR: 1.82, CI: 1.07-3.10), and stress at home (OR: 2.17, CI: 1.35-3.49). Twenty-six percent of the cohort (n=86) was noted to have the most negative illness perception, and on multiple logistic regression analysis, it was significantly associated with male gender (OR: 0.24, CI: 0.11-0.53), age of onset of arthritis (OR: 0.96, CI: 0.94-0.99), and worse HAQ scores (OR: 3.7, CI: 2.2-6.1). Conclusions Important adverse factors contributing to non-adherence and negative illness perception highlighted in this study were stress at home, female gender, and younger age of patients.

Correlation Between Quantitative Anti-dsDNA Levels with Severity of Proteinuria in Systemic Lupus Erythematosus Patients.

OBJECTIVE: To evaluate the correlation of quantitative anti-dsDNA level with proteinuria levels in patients with lupus nephritis in a tertiary care hospital. STUDY DESIGN: In this prospective cross-sectional study, 76 patients of newly diagnosed SLE coming to Fatima Memorial Hospital were included in the study period between January 2020 to June 2020. Demographic data such as age, gender, lupus manifestations such as serositis, arthritis, mucocutaneous disease, and neuropsychiatric manifestations were recorded. Quantitative anti-dsDNA was measured by enzyme-linked immunosorbent assay and proteinuria was estimated by 24h urinary protein collection. Data was analyzed by SPSS 23. Association between categorical variables was assessed using chi-square test. For comparison of categorical independent and continuous dependent variable t-test or Mann-Whitney U test was applied. RESULTS: The median age of the cohort was 29 (with inter quartile range - IQR - of 13) years. The female gender comprised of 68 (89.4%) of the cohort population. The median anti-dsDNA level was 54.9 (183.6 IQR) IU, and baseline proteinuria of the cohort was 520mg/dL (1.49 IQR). There was a significant association of anti-dsDNA level with systemic features such as arthritis (p=<0.01), serositis (p=<0.01) and, Raynaud's phenomenon (p=<0.01). NPSLE and mucocutaneous features did not show statistically significant association (p=0.91 and 0.14 respectively). Baseline anti-dsDNA showed a statistically significant correlation with baseline proteinuria levels (p=<0.01). CONCLUSION: Quantitative anti-dsDNA is directly correlated with nephritis measured as proteinuria, and can be detected even before organ involvement. Hence, it can determine disease course and guide early treatment.

Frequency of Urinary Tract Infections in Type 2 Diabetic Patients Taking Dapagliflozin.

Background Urinary tract infections (UTIs) are common in patients with diabetes. The use of sodium-glucose cotransporter-2 inhibitors (SGLT2i) to achieve good glycemic control increases glucose levels in urine. This glycosuria further enhances the risk of UTIs. This study aimed to evaluate the frequency of UTIs in patients with type 2 diabetes receiving the SGLT2i dapagliflozin as an add-on therapy. Methods We conducted this cross-sectional study at the Endocrinology Department of Hayatabad Medical Complex in Peshawar from April 2020 to September 2020. A total of 400 patients with diabetes receiving either 5 mg or 10 mg of dapagliflozin as an add-on therapy for the treatment of type 2 diabetes were included in this study. We collected blood and urine samples from participants and measured glycosylated hemoglobin levels. Urine samples were cultured on cysteine lactose electrolyte deficient agar. We used IBM SPSS Statistics for Windows, version 25.0 (IBM Corp., Armonk, NY) to analyze our data. Results The prevalence of UTIs in diabetic patients receiving 5 mg or 10 mg of dapagliflozin was 5.3%. Women were more affected (76.2%) than men (p < 0.05). UTIs were more prevalent in patients older than 50 years (85.7%) than in any other age group. The dose strength of dapagliflozin was not associated with UTIs (p > 0.05). Conclusion This study examined UTIs in patients taking dapagliflozin for the treatment of type 2 diabetes. These infections were mild to moderate and were treated easily. None of these infections caused the patient to discontinue the treatment. Dapagliflozin is well-tolerated in patients with diabetes but should be used with appropriate caution and monitoring.

Clinical and serological characteristics of systemic sclerosis: Experience of a tertiary care center in Pakistan.

Objectives: This study aims to evaluate the clinical and serological characteristics of systemic sclerosis (SSc) in Pakistani population. Patients and methods: This prospective, cross-sectional study included a total of 38 patients (6 males, 32 females; mean age: 34.5±1.5 years; range, 16 to 60 years) with SSc who were admitted to our rheumatology clinic between November 2019 and January 2020. We evaluated the clinical, serological, and radiological features of SSc patients. Results: Thirty-four (89.5%) patients developed Raynaud phenomenon at the time of disease onset, while sclerodactyly was found in 34 (89.5%), digital ulcers in 25 (65.8%), and tendon friction rub in 12 (31.6%) patients. Interstitial lung disease was present in 30 (78.9%) patients with a higher prevalence in diffuse scleroderma (100%) than in limited scleroderma (70%) (p=0.01). Pulmonary hypertension was present in 18 patients with a significantly higher prevalence in diffuse disease (57.1%) than limited disease (11.8%) (p<0.01). Thirty (78.9%) patients had impaired pulmonary function tests. Fibromyalgia was present in seven (18.4%) patients, and depression was present in 10 (26.3%) patients. Antinuclear antibody (ANA) was positive in 30 (78.9%) patients. Anti-Scl-70 antibodies were present in 24 (63.2%) patients with a significant association with diffuse disease (85% vs. 35.3%, respectively; p<0.01). The anti-centromere antibodies (ACA) were present in 20 (52.6%) patients with a significantly higher rate in limited disease (94.2% vs. 19.0%, respectively; p<0.01). Conclusion: Scleroderma has a female preponderance. Raynaud phenomenon is the most initial clinical feature followed by other manifestations of a variable course and disease severity.

Past and Future Perspectives for Hepatitis B and C in Pakistan.

Background Hepatitis B and C are viral infections of the liver transmitted by blood contamination. These infections are endemic in Pakistan and put a tremendous burden on its healthcare system. We conducted this study to assess the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in Gujranwala, Pakistan, from 2010 to 2015 and determine the trend of future infections for a prediction of the disease burden by 2030 so policymakers can make informed decisions. Methods We conducted a retrospective cross-sectional study of 66,308 healthy blood donor samples at District Headquarters Teaching Hospital in Gujranwala from January 2010 to December 2015. Samples were screened for HBV and HCV using the kit method, and data were analyzed using IBM SPSS Statistics for Windows, version 20.0 (IBM Corp., Armonk, NY). We applied a least squares regression to our results to predict HBV and HCV incidence in 2030. Results A total of 715 samples (1.08%) were positive for HBV and 1,846 samples (2.78%) were positive for HCV. Our projections indicate that 3.25% of patients in Pakistan will be positive for HBV, and 6.36% will be positive for HBC by 2030. Conclusion We found an unexpectedly greater burden of HBV and HCV in the recent past than at current levels. The predicted percentages of future burden over the next decade were alarmingly high. These data necessitate implementing preventive and therapeutic measures by policymakers to reduce the disease burden and mortality in Pakistan.

Empyema thoracis: management outcome.

BACKGROUND: Empyema thoracis results from postpneumonic effusion of bacterial origin or trauma. If untreated it may convert to fibro-purulent or an organising stage. METHODS: This study was conducted at cardiothoracic unit of Ayub Teaching Hospital Abbottabad from Jan 2008 to Aug 2009. Patients with diagnosis of empyema thoracic were studied. Their clinical features and investigations were recorded on a proforma. Antibiotics alone, aspiration, chest intubation, rib resection or decortication were performed where required. RESULTS: Out of 71 patients, males were 58 (81.69%) and females were 13 (18.3%). Majority of the patients (24, 33.8%), were below 20 years of age. Most of the patients (59, 83.09%), were from the poor socioeconomic class. Forty-one (57.76%) patients were smokers, 12 (16.9%) were diabetic, and 39 (54.92%) were hypertensive. Cough was the most common complain (62, 87.32%). Forty (56.33%) had more than 50% involvement of hemi thorax. In 44 (61.97%) cases, cause was tuberculosis. Fifty-one (71.83%) patients were treated with tube thoracostomy and 13 (18.3%) required decortication. CONCLUSION: Empyema thoracis commonly affects males. Apart from clinical assessment, x-ray chest is an important and simple investigation to detect empyema thoracic. Mostly tube drainage cures the diseases but in case of failure other options are also available.

Carcinoma of prostate in clinically benign enlarged gland.

BACKGROUND: Carcinoma of the prostate is one of the common tumours of old age in men. This cross sectional study was conducted to detect carcinoma of prostate in clinically benign enlarged gland and to evaluate the efficacy of Digital rectal Examination in detection of prostatic cancer in patients presented at Khyber Teaching Hospital, Peshawar from July 1998 to July 1999. METHODS: Patients presenting with lower urinary tract symptoms over the age of 50 years were evaluated on English version of International Prostate Symptoms Score (IPSS), clinically examined and post-voiding residual urine determined on abdominal sonography. The selection criteria were; Severe IPSS, absence of signs of malignancy on Digital Rectal Examination (DRE) and post-voiding residual urine more than 100 ml. Thus a total 100 patients were selected for further study. Four ml blood was taken to assess Prostate Specific Antigen (PSA) level pre-operatively. All these patients underwent either transvesical prostatectomy or transurethral resection of prostate (TURP) and enucleated prostatic tissues were sent to histopathology. RESULTS: Eighty-five percent patients had PSA level up to 10 etag/ml. PSA level of 15 (15%) patients were above 10n gm/ml out of which 13 (13%) patients were having PSA in range of 11-12 etag/ml and two (2%) had PSA level between 20-25 etag/ml. Histopathology report of 2% patients turned out as adenocarcinoma of the prostate. CONCLUSION: Out of 100 patients who were having clinically benign DRE findings, 2 turned out as Carcinoma of the prostate histologically.

Case report of a lupus patient with a severe flare and miliary tuberculosis: need for proper guidelines for management.

Systemic lupus erythematosus (SLE) is an autoimmune disease that is frequently treated with high doses of corticosteroids and other immunosuppressive drugs. Thus patients with SLE are at increased risk for infections with several pathogens including Mycobacterium tuberculosis. There are no established guidelines available for treatment of tuberculosis in SLE patients with high disease activity due to lack of relevant studies and management based more on physician expertise. We report a case of a young SLE patient with high disease activity index (SLEDAI19) as evidenced by the presence of a vasculitic rash, non-healing ulcer on forearm and proteinuria of >1 g/d along with miliary tuberculosis. She was treated with intravenous methylprednisolone pulse up to 3 g and antituberculous therapy, but the result was a fatal outcome. This case report emphasizes the need for formal guidelines for co-management of active tuberculosis and SLE with high disease activity.

Objetivo: Evaluar la correlación del nivel cuantitativo de anti-dsDNA con los niveles de proteinuria en pacientes con nefritis lúpica en un hospital de tercer nivel. Diseño del estudio: En este estudio transversal prospectivo se incluyeron 76 pacientes de LES recién diagnosticados que acudieron al Fatima Memorial Hospital en el período de estudio entre enero de 2020 y junio de 2020. Se registraron datos demográficos como edad, sexo, manifestaciones de lupus como serositis, artritis, enfermedad mucocutánea y manifestaciones neuropsiquiátricas. El anti-dsDNA cuantitativo se midió mediante un ensayo inmunoabsorbente ligado a enzimas y la proteinuria se estimó mediante la recogida de proteínas en orina de 24 horas. Los datos fueron analizados por SPSS 23. La asociación entre variables categóricas se evaluó mediante la prueba de χ2. Para la comparación de variable dependiente continua e independiente categórica se aplicó la prueba t o la prueba u de Mann Whitney. Resultados: La mediana de edad de la cohorte fue de 29 años (con rango intercuartil – IQR – de 13). El género femenino comprendía 68 (89,4%) de la población de la cohorte. El nivel medio de anti-dsDNA fue 54,9 (183,6 IQR) UI, y la proteinuria basal de la cohorte fue de 520mg/dL (1,49 IQR). Hubo una asociación significativa del nivel de anti-dsDNA con características sistémicas como artritis (p=<0,01), serositis (p=<0,01) y fenómeno de Raynaud (p=<0,01). El NPSLE y características mucocutáneas no mostraron asociación estadísticamente significativa (p=0,91 y 0,14, respectivamente). El anti-dsDNA basal mostró una correlación estadísticamente significativa con los niveles basales de proteinuria (p=<0,01). Conclusión: El anti-dsDNA cuantitativo se correlaciona directamente con la nefritis medida como proteinuria y puede detectarse incluso antes de la afectación de órganos; por lo tanto, puede determinar el curso de la enfermedad y orientar el tratamiento temprano.(AU)
