RESUMEN
The clinical presentation of COVID-19 varies from being asymptomatic to developing acute respiratory distress syndrome and multi-organ dysfunction. The diffuse microvascular thrombi in multiple organs seen in the autopsy of COVID-19 patients are similar to that of thrombotic microangiopathy (TMA). TMA is characterised by thrombus formation in the microvasculature with laboratory findings of microangiopathic haemolytic anaemia (MAHA) and thrombocytopenia. A 49-year-old male presented to the Aga Khan University Hospital, Karachi. with fever, diarrhoea, altered level of consciousness, and a positive nasopharyngeal swab for SARS-CoV-2. He developed severe thrombocytopenia, MAHA with 5.8% schistocytes, and worsening renal function on the sixth day of admission. Diagnosis of thrombotic thrombocytopenic purpura (TTP) was established based on PLASMIC score, and he was successfully treated with intravenous (IV) Methylprednisolone, therapeutic plasma exchange and IV Rituximab. The case emphasises the need to keep TTP in the differential diagnosis when a patient with COVID-19 develops severe thrombocytopenia, acute renal failure, or impaired level of consciousness, since prompt diagnosis and treatment is necessary to gain favourable outcome.

Atypical Haemolytic Uraemic Syndrome (aHUS) is considered an uncommon pathology that usually affects young adults and causes acute kidney injury which can further lead to End Stage Renal Disease (ESRD). Here we present the case of a previously healthy young boy who was diagnosed as a case of atypical HUS on renal biopsy in Sheikh Zayed Hospital Lahore. His C3 was low, while ANA and C-ANCA P-ANCA were in normal range; multiple sessions of plasmapheresis were conducted, whereas IV Methylprednisolone was also given during both admissions (the patient had to be readmitted six months later after having been discharged on improvement). After that, his GFR improved along with other laboratory parameters. Rituximab was also offered but the family refused due to affordability issue.

OBJECTIVE: To calculate the incidence of post-transplant erythrocytosis, and to assess the response to treatment. METHODS: The prospective study was conducted from April 2016 to April 2018 at the Department of Nephrology, Bahria International Hospital, Lahore, Pakistan, and comprised patients undergoing renal transplantation who were evaluated and followed up for 12 months. Patients having haemoglobin levels ≥17gm/dl were labelled as having polycythemia. Data was analysed using SPSS 21. RESULTS: Of the 94 total patients, 69(73.4%) were enrolled. During follow-up, 2(2.9%) of them died, and, thus, the final sample stood at 67(71.3%); 57 (85%) males and 10(15%) females. The mean age of the sample was 32.6±8.8 years. Overall, 19(28.4%) patients developed polycythemia and they were either given angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers. Of these 19 patients, 11(57.8 %) responded to the treatment, while 8(42.1%) required phlebotomy. Further, 3(15.7%) patients required one phlebotomy, while 5(26.3%) who had glomerular filtration rate >30% had to have repeated phlebotomy. CONCLUSIONS: The incidence of post-transplant erythrocytosis was significantly high at 28.4%.

Fusarium wilt of chili caused by the fungus Fusarium oxysporum f. sp. capsici (FCO) severely reduces the production of chili worldwide. There is growing evidence of resistance to commercial fungicides targeting succinate dehydrogenase (Sdh) of FCO soliciting the development of new Sdh inhibitors (SdhIs). In the current work, optimized docking and virtual screening were used to mine twelve SdhIs from the ZINC database, followed by in vitro antifungal evaluation on spore and radial mycelium development. Four new promising SdhIs exhibiting a mean mycelium inhibition rate greater than 85.6% (F = 155.8, P = 0.001, P < 0.05) were observed on ten strains of virulent and resistant FCO. Importantly, three of the discovered molecules exhibited potent spore germination inhibition (≥ 80%, P = 0.01, P < 0.05) compared to the commonly used fungicide penthiopyrad. A significant positive correlation (r* ≥ 0.67, P < 0.05) between the activities of the newly discovered SdhIs compared to penthiopyrad against all tested FCO strains indicated a broad-spectrum fungicidal activity. The current findings indicate that the four SdhI's discovered could judiciously replace certain commercial SdhIs that some FCO displays resistance to.

RESUMEN
OBJECTIVE: To assess the frequency and time of onset of new-onset diabetes after transplant (NODAT) and its associated factors. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Nephrology, Bahria International Hospital, Lahore, Pakistan, from April 2016 to April 2018. METHODOLOGY: NODAT was diagnosed according to American Diabetes Association Criteria with fasting plasma glucose >126 mg/dl or random plasma glucose >200 mg/dl. Those with pre-existing diabetes and follow-up duration less than 12months, were excluded. Patients were divided in two groups: with and without NODAT, for statistical comparison. RESULTS: The study included 115 patients, 101 were males and the median age was 35.0 (29.0-46.0) years. During the one-year period of follow-up, 28 (24.3%) patients developed NODAT. The mean time of onset of NODAT was 5.3 ± 3.6 months. Family history of diabetes was positive in 46% patients in NODAT group, which was significantly higher as compared to 5.7% in non-NODAT group with p-value of <0.001, which is significant. All patients with more than three HLA mismatches developed NODAT. The mean fasting glucose levels (FPG) before transplant in NODAT group was 96.6 ± 15.4 mg/dl, which was significantly higher than FPG of non-NODAT group, where it was 80.5 ± 12.2 mg/dl. It was interesting to note that 35.7% of hepatitis patients developed NODAT as compared to 6 % in non-NODAT group with p = 0.001. CONCLUSION: NODAT was observed in 24.3% patients. The pre-transplant FPG, family history of diabetes, increased HLA mismatches, and hepatitis C infection were the major associated factors. Key Words: New onset diabetes after transplant, Fasting plasma glucose, Renal transplant.

BACKGROUND: Diabetes mellitus has become a major emerging health concern. Its burden, estimated to be 451 million in 2017, has been projected to rise to 693 million by 2045. This will bring a rise in the prevalence of its associated complications. There is a wide spectrum of non-diabetic renal disease (NDRD) known to be present in diabetic patients with variable prevalence. However, the majority of diabetes mellitus (DM) patients with renal disease are yet not biopsied and the diagnosis of diabetic nephropathy (DN) is presumed on clinical grounds. METHODS: It is a retrospective cross-sectional study. We selected a total of 126 cases of renal biopsies with a history of type 2 diabetes mellitus. Demographic data was collected from the medical records and pathology reports while all cases were evaluated by reviewing the archived slides. RESULTS: Patients were categorized into group 1 with isolated NDRD, group 2 showing NDRD mixed with DN and group 3 with isolated DN. Thirty-four (27%) cases had isolated NDRD (group 1), 14 (11%) had NDRD mixed with DN and 78 (62%) patients had isolated DN. NDRD, either alone or in combination with DN, was found to be present in 48 patients with an overall prevalence of 38%. CONCLUSION: Our study concludes that NDRD is frequent in type 2 diabetes mellitus patients. Renal biopsy remains the key diagnostic tool in such cases, providing crucial information for proper management of the underlying pathology.
