ABSTRACT
Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread to almost every country on the globe, and each country is reporting the symptomatic presentation of their patients to give better insight into the various clinical presentations of SARS-CoV-2. However, the epidemiological literature from Pakistan is scanty. Methods We retrospectively analyzed data from 412 patients who were residents of East Karachi and tested positive for SARS-CoV-2 between February 26 to April 24, 2020. Patients' demographics, symptoms, travel and contact history, and outcomes were recorded. All statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 22 (IBM SPSS Statistics for Windows, IBM Corp, Armonk, NY). Results Most of the patients were male (64.6%), the majority (43.3%) belonging to the 21- to 40-year age group. Most of the patients (65.5%) were residents of Gulshan Iqbal. A total of 15.8% of the patients were admitted to the hospital, and 3.9% of patients expired. The three most common presenting symptoms were fever (74.8%), cough (60.4%), and flu (35.5%). The majority of patients (89.3%) gave a history of contact with SARS-CoV-2 patients. Conclusion The number of SARS-CoV-2 cases is rapidly increasing in Karachi, Pakistan. There is a need to educate the population about the most common sign and symptoms of the virus so that individuals can identify these symptoms and get themselves tested. The concerned authorities should devise an adequate and effective plan to flatten the infectivity curve.
ABSTRACT
To determine the patterns of the prevalent glomerulonephritis (GN) in our region, we studied the results of 511 consecutive renal biopsies performed on patients with proteinuria, hematuria and mild to moderate renal impairment at the Aga Khan University Hospital during a period of 18 years from January 1990 to December 2008. Primary glomerular disease accounted for two-thirds of the glomerular diseases, which in turn constituted 49% of all renal biopsies. The most common histological lesion was membranoproliferative disease (28%). Membranous GN was the second most common lesion (19%), followed by minimal change disease (16%) and focal segmental GN (11%). Secondary glomerular disease comprised 30% of glomerular diseases (21% of all the renal biopsies), with lupus nephritis forming the most common lesion (34%) followed by amyloidosis (22%), diabetic nephropathy (10%), Wagener's granulomatosus and post-infectious GN (9% each). Tubulointerstitial diseases accounted for 16% of all the renal biopsies. We conclude that there exists a wide variability in the different categories of primary and secondary glomerular diseases in our region as compared with different parts of the world. Future studies should be directed to analyze the causes for these variations.
