Nephrotic Syndrome and Posterior Reversible Encephalopathy Syndrome as Clinical Presentations of Gemcitabine-Induced Thrombotic Micro-Angiopathy.

Gemcitabine-induced thrombotic micro-angiopathy (GiTMA) is a very rare pathology of micro-vascular occlusion with a poor prognosis. In this case report, we present a young male with pancreatic carcinoma who received gemcitabine as adjuvant chemotherapy and developed thrombotic micro-angiopathy (TMA) manifesting as nephrotic syndrome with renal dysfunction and posterior reversible encephalopathy syndrome (PRES). The case was successfully managed with discontinuation of the drug and conservative management. The pathogenesis of GiTMA might be direct endothelial dysfunction with consequent activation of the clotting system. The role of plasma exchanges and monoclonal antibodies is unclear in drug-induced TMA.

Postpartum Pulmonary-Renal Syndrome with Thrombotic Microangiopathy in Systemic Lupus Erythematosus.

Postpartum pulmonary syndrome as lupus flares in inactive or mild lupus is uncommon. The diagnosis and management of postpartum lupus flare in second pregnancy presenting with crescentic lupus nephritis (LN), secondary thrombotic microangiopathy (TMA), and severe lupus vasculitis in an undiagnosed systemic lupus erythematosus is extremely challenging. Here, in this case report, we present a young lady who presented with postpartum acute kidney injury (AKI) with systemic complaints about 4 weeks post-term uneventful delivery. Renal biopsy was suggestive of crescentic LN with severe lupus vasculitis. The stormy course was further complicated with diffuse alveolar hemorrhage, portal venous thrombosis, TMA, and anuric AKI requiring renal replacement therapy. She received multiple sessions of plasmapheresis, steroid, intravenous immunoglobulin, inj. cyclophosphamide, and started showing improvement after about 6 weeks of presentation.

Prolonged fever and pancytopenia in a case of severe dengue may be secondary hemophagocytic lymphohistiocytosis.

The diagnosis of secondary hemophagocytic lymphohistiocytosis (HLH) in the setting of dengue fever is usually challenging but should be kept in mind in patients with persistent fever, pancytopenia, and multiorgan dysfunction. We report a case of severe dengue who had prolonged fever with multiorgan involvement, laboratory features fulfilling the diagnostic criteria of HLH, and had a prompt response with high-dose corticosteroids. Physicians should be aware of this rare clinical syndrome and its variable clinical presentations so that fatal outcomes can be prevented with prompt and appropriate treatment.

Post Covishield (ChAdOx1 nCoV-19) Vaccination: New Onset Focal Segmental Glomerulosclerosis Resistant to Steroid and Calcineurin Inhibitor.

With the ongoing mass COVID vaccination program, various case reports link the COVID-19 vaccines with heightened off-target immune responses leading to de novo development or relapse of various glomerular diseases. Very few glomerular diseases (totally nine published cases to date) have been reported post ChAdOx1 nCoV-19 (Oxford-AstraZeneca) vaccination compared to more potent m RNA vaccine. In this case report, we present a case of de novo focal segmental glomerulosclerosis (FSGS) post ChAdOx1 nCoV-19 vaccination resistant to steroid and calcineurin inhibitor treatment. To our knowledge, this is the first case of FSGS tip variant reported after the ChAdOx1 nCoV-19 vaccination and the second de novo FSGS case post COVID vaccination (any types of COVID vaccines). We may expect more such types of cases resistant to conventional therapy as the global penetration of vaccination programs will improve.

The Epidemiology of Intensive Care Unit Readmissions and Proposed Discharge Protocol for a Tertiary Care Hospital.

BACKGROUND: Intensive Care Unit (ICU) readmissions during the same hospitalization are associated with increased hospital stays, morbidity and mortality. Whereas mortality rates in patients admitted to the ICU for the first time may range from 10 to 20% depending on various factors, readmission mortality rates can be up to 50 to 70%. Factors leading to readmission in ICU in Indian Armed Forces Hospitals have not been well studied till date. METHODS: This was a record based cross sectional descriptive study conducted at the ICU of a tertiary care Armed Forces hospital. Demographic and clinical data of ICU patients were analysed. ICU admission and discharge data for the duration of last three years were acquired from admission and discharge registers and Hospital Informatics system (HIS) software. The primary outcome was readmission rates to ICU during the same hospitalization. Secondary outcomes included diagnosis at time of index admission (first time admission) to ICU and at readmission, multiple readmissions to ICU and mortality rates in readmitted patients. RESULTS: There were 3021 admissions to the ICU during the study period. 422 patients succumbed to illness during initial admission resulting in a mortality rate of 14%. 198 patients were readmitted to the ICU. The readmission rate to the ICU was 7.8%. The mortality rate in readmitted patients was 31% as compared to the ICU mortality rate of 14%. The triggering factors for readmission were usually respiratory or cardiac decompensations. CONCLUSION: Readmission to ICU occurred in about 7.8 % of all ICU patients in our study. ICU readmissions increase the risk of adverse outcomes. Objective measures in the form of a discharge protocol incorporating the stability and work index for transfer (SWIFT Score) may help minimizing readmission to ICU. Such protocols must be in place while shifting any patients from ICU so as to improve outcomes in patients of tertiary care hospitals.

Burkholderia cepacia Bacteremia Complicated by Intracranial Abscesses and Immune Reconstitution Inflammatory Syndrome in a Renal Transplantation Recipient.

Burkholderia cepacia is almost always a colonizing organism rather than an infecting organism, but it may be pathogenic in immunocompromised individuals when isolated from body fluids that are ordinarily sterile. When recovered from blood culture it may present infection, pseuedo infection, or actual infection from contaminated intravenous fluids. We present a case of a renal transplant recipient patient who developed B. cepacia bacteremia following central venous cannulation. The subsequent clinical course was of worsening quadriparesis, which on neuroimaging revealed multiple brain and spinal abscesses. Following two weeks of intravenous antibiotics, his clinical features further worsened and the size of lesions further increased, which was suggestive of immune reconstitution inflammatory syndrome. With an increased steroid dose and continuation of the same anti-biotics, there was a regression of the lesions and significant clinical improvement.

Early Experience with Sine Wave Technique for Superficialization of a difficult to cannulate Arterio Venous Fistula.

OBJECTIVE: To highlight safety and efficacy of sine wave technique (SWT) in superficializing deep arterio venous fistula (AVF) and managing infiltrations and other complications. METHODS: It is a single center observational study done from Jul 2017 to July 2020. All successive cases of deep AVFs, aneurysm / pseudoaneurysms of AVFs, and AVFs requiring open venoplasty were managed with SWT. Data was collected prospectively and analyzed. SWT is based on random pattern skin flaps. Using ultrasound, a line is marked on either side of centre line (AVF) at a distance of approximately 1.5-2 cm. A sine wave is drawn starting from either of the lines to the other with multiple crests and troughs. The base of flap should be double the height of the flap, that is, about 3-4 cm. Skin is incised and flaps are raised at level of AVF. Excess fat is removed. A sliver of unhealthy skin can be sacrificed if required. Flaps are sutured back to restore sine wave continuity. RESULTS: SWT was used in a total of eleven patients. Median age was 58 years (range 10-67 years). Eight were females and three males. One was radio-cephalic and rest were brachio-cephalic AVFs. Eight AVFs were deep with median depth of 10.25mm (range 8-13mm), median body mass index of 25.5 kg/m2 (range 23.9-26.5kg/m2), median vein diameter of 7 mm (range 6-8 mm), and median flow rate of 1137.5ml/min (range 650- 1380 ml/min). Out of eight, four AVFs presented with infiltration. In other three, SWT was used for exposing AVF to treat underlying pathology (one case each of aneurysm, pseudoaneurysm & stenosis). Ten cases were done under local or regional anesthesia and one under general anesthesia. There was no peri-operative mortality or loss of AVF. Transient limb oedema developed in one case. Median time to cannulate was 20 days (range 13-28 days). Median follow up was 13 months (range 6 - 31months). Cumulative patency at 18 months was 90% (95% CI 47.3%-98.53%) and 45 % (95% CI 9.9%-87.1%) at 24months and at the end of the study. CONCLUSION: SWT is safe and effective in superficialization of deep / difficult to cannulate AVF as well a good approach to treat complications like infiltration. Post procedure cannulation time is reasonably short.

Clinical Spectrum of Rheumatic Manifestations in HIV Infected Males at a Tertiary Care Hospital.

BACKGROUND: In the current era of effective Anti retroviral therapy (ART), and Human Immunodeficiency Virus (HIV) infection becoming a chronic illness, there has been a gradual rise in the prevalence of rheumatic manifestations associated with this disease. These are characterized by a modified clinical course and widened spectrum of a few emerging rheumatic manifestations seen with HIV infection. AIMS AND OBJECTIVES: To assess the type, frequency, prevalence and clinical spectrum of rheumatic manifestations among &male patients followed at an HIV clinic of a tertiary care defence hospital. MATERIALS AND METHODS: All male patients with confirmed HIV infection at the study centre were studied after obtaining informed consent. A detailed history was taken including the date of seropositivity, symptoms of rheumatic disease, family history of rheumatic illness, and treatment history with ART. A detailed general and systemic examination was performed and rheumatic symptoms guided appropriate investigations were carried out on as required basis. RESULTS: 879 confirmed HIV cases were evaluated for rheumatic manifestations during the study period. Of these 499 cases were newly detected HIV cases and the rest 380 were old cases on follow up. Rheumatic disorders were diagnosed in 16 cases (1.82%). Spondyloarthropathy was the commonest presentation i.e. 5 out of 16 cases (31.25 % of the rheumatic disorders). Mean age was 37 years (range 27-52 yrs). 2 patients of the study group had the rheumatic illness prior to detection of HIV. Psoriatic Arthritis (0.114 %) was seen in 1 patient who was HLA B-27 negative. Reactive arthritis (0.227 %) was noted in 2 patients. 1 patient had cutaneous small vessel vasculitis (0.114 %), whereas 1 of the patient developed DLE (0.114 %) over neck. HIV related non specific polyarthritis (0.114 %) of the large joints was noted in 1 patient who was RF negative, while polyarthralgia (0.340 %) was noted in 3 patients. 10 patients (60 %) had CD 4 count < 200 cells/ µL, whereas 6 patients had a CD 4 count between 200 and 500 cells/µL. 13 out of 16 patients detected to have rheumatic illnesses were on ART. CONCLUSION: With the advent of ART, the clinical spectrum of HIV infection is changing as a chronic treatable disease. Present study consisting mainly adult males, showed only 1.82 % prevalence of rheumatic disorders in HIV infection. Early diagnosis, availability of ART and prompt treatment of opportunistic infections have changed the clinical profile of HIV patients. Impact of ART in producing and affecting the clinical spectrum of rheumatic disease has to be kept in mind while treating HIV-infected patients.

Open-label randomized control trial of hydroxychloroquine in patients with moderate to severe coronavirus disease 2019 infection.

BACKGROUND: At onset of coronavirus disease 2019 (COVID-19) pandemic, hydroxychloroquine (HCQ) was repurposed for treatment of patients based on reports that it had in vitro activity. The aim of this study was to find out if HCQ reduces number of days of hospitalization when given to patients with moderate to severe COVID-19 infections who require hospitalized care. METHODS: This was an open-label randomized control trial of HCQ administered 400 mg twice on day 1, then 400 mg once daily from day 2 to day 5 in patients with moderate to severe COVID-19 infection. Assessment was not blinded. Standard of care was given to both arms.Primary outcome was number of days of hospitalization till discharge or death. RESULT: One hundred ten patients (55 in each arm) were included. Mean age was 58 years. Baseline characteristics were well matched. There was no difference in the primary outcome (13.67 vs 13.89; p = 0.98). Number of deaths were more in HCQ arm (RR: 1.81; 95% CI: 1.13-2.93; p = 0.03). There was no difference in number of days on oxygen or normalization of oxygen saturation, number who needed ventilator, days to ventilator requirement and days on ventilator. Twenty-nine patients in control arm received remdesivir. When adjusted analysis was done after removal of these patients, there was no difference in primary or secondary outcomes. Number of deaths in adjusted analysis were not significant (RR: 1.28; 95% CI: 0.87-1.88; p = 0.37). CONCLUSION: HCQ does not change the number of days of hospitalization when compared with control.

Demographic Characteristics, Outcome and Complications of Renal Transplantations at a Tertiary Care Center in South India.

BACKGROUND: Renal transplantation is the treatment of choice for selected patients with end-stage renal disease. In this study, we present our experience and follow up data of renal transplantations done at this center with special emphasis on demographic characteristics, outcome and its complications. MATERIALS AND METHODS: All those patients who underwent renal transplantations and had been followed up at this center were studied and their details were recorded. For living donor transplantation, donor and recipient were evaluated in detail. Graft loss was defined as the patient became dialysis-dependent or underwent second renal transplantation. RESULTS: A total of 250 renal transplantations were done during the study period. 16.4% of total transplantations were cadaveric transplants. Recipients mean age was 38.5±11.64 yrs and donor mean age was 42.25 ±10.79 yrs. The majority of the recipients were male (72.4%) while female donors were predominant among living donors(59.3%). Mean graft survival time was 98.2 months (95% confidence interval [CI]:72.2-114.4). Mean patient survival time was 104.5 months (95% confidence interval [CI]:82.4-126.2). CONCLUSION: There is increasing no. of cadaveric renal transplants due to well established deceased donation programs in the state. Our patient and graft survival are comparable. Most of the immediate graft loss was due to acute rejection and late graft loss was due to chronic antibody-mediated rejection.

Anaphylaxis: An Uncommon Cause of Rhabdomyolysis-Related Acute Kidney Injury.

Anaphylaxis is an acute, severe, and potentially lethal form of an allergic reaction. It can lead to a sepsis-like syndrome and multisystem involvement with complications. It can cause distributive shock with preferential blood supply to vital organs, at the expense of blood supply to skeletal muscle. Skeletal muscle ischemia leads to the fast depletion of myocyte energy source and a cascade of inflammatory reactions leading to myocyte injury and death. Myocyte lysis or rhabdomyolysis releases the cellular contents into circulation. Rhabdomyolysis is not an oft-discussed complication of anaphylaxis. We describe a 21-year-old male with no known comorbidity who presented with anaphylactic shock after consuming one tablet paracetamol + ibuprofen and was found to have rhabdomyolysis-related acute kidney injury.

A case of cholesterol embolization syndrome mimicking rapidly progressive renal failure causing end-stage kidney disease.

Cholesterol embolization syndrome is an uncommon complication of coronary angioplasty. Its clinical manifestations are nonspecific and may be ascribed to other causes mimicking vasculitis syndrome. In an appropriate clinical setting, the diagnosis can be confirmed by tissue biopsy. In this case report, we present a middle-aged male who presented with cutaneous and renal manifestations within two weeks of primary angioplasty. The patient had progressive clinical deterioration in the form of dry gangrene of toes and end-stage renal disease requiring surgical amputation and maintenance hemodialysis respectively within two months of symptoms onset.

Renal Transplantation Significantly Improves Autonomic Function with Normalization of Baroreflex Sensitivity as Early as Three-Month Post-transplantation.

The most common cause of mortality in chronic kidney disease patients is cardiovascular events. Cardiovascular autonomic dysfunction is likely to contribute high incidence of cardiovascular mortality, and in addition to adrenergic overdrive in these patients, there is the presence of impaired reflex control of both sympathetic and parasympathetic outflow to the heart and vasculature. Very few studies are available which show that renal transplantation (RT) improves the baroreflex function along with improvement in cardiovascular variability parameters. This prospective study was designed for the assessment of the autonomic function, i.e., heart rate variability (HRV), blood pressure variability (BPV), and baroreflex sensitivity (BRS) in end-stage renal disease (ESRD) patients before RT and three and six months after RT and to study the effects of RT on cardiac and vascular autonomic tone and on BRS. We studied 81 ESRD patients prospectively slated for RT but only 64 patients (mean age: 33 years) completed both three and six months visits after RT for autonomic function study. Patients were evaluated in detail clinically as well as routine biochemical parameters were done on every three visits. Baroreflex function was quantified by the sequence method. Assessment of short-term HRV and BPV were done using power spectrum analysis of RR intervals and systolic BP by frequency domain analysis. The parameters of HRV after RT showed significant changes in high-frequency domain measures six months post-RT but not in low frequency. HRV in total power was also statistically significant as early as three months postrenal transplant and remained at six months. The favorable effect of RT on decreasing BPV and improving BRS is seen by as early as three months.

Improvement in Pulse Wave Velocity and Baroreflex Sensitivity Three-and Six-Month Postrenal Transplantation.

Cardiovascular diseases are an important cause of mortality in end-stage renal disease (ESRD) and increased arterial stiffness and autonomic dysfunction have been proposed to explain part of this excess cardiovascular risk. This prospective study was designed with the aim of noninvasive assessment of the vascular function, i.e., arterial stiffness in the form of pulse wave velocity (PWV) and autonomic function in the form of baroreflex sensitivity (BRS) in ESRD patients before renal transplantation (RT) and three and six months after RT. The study was conducted in 64 patients of ESRD slated for RT in the Department of Nephrology and was being followed up during all three visits (pretransplant, three-, and six-month posttransplant). The period of patient recruitment and data collection lasted for approximately 1½ years. Although PWV did not show a significant change, the change in PWV was negatively correlated with baseline PWV, and it was statistically significant. The BRS after RT had a significant improvement as early as three months. The correlation between change in PWV and change in BRS postrenal transplant was not seen. RT improves BRS, but it is still unknown that it is through amelioration of arterial properties or neural components or/and a relative contribution of both. We suggest that the improvement in BRS postrenal transplant is probably because of the improvement in autonomic neural functions rather than the improvement in compliance of barosensitive regions of large arteries.

The therapeutic dilemma in pre-transplant asymptomatic aspergilloma: A case report and review of literature.

Aspergillus species are ubiquitous, and inhalation of infectious conidia is not so uncommon. With immunosuppression, it can invade adjacent structures and lead to widespread invasive disease. There is no randomized, prospective trial for optimized treatment including the antifungal and surgical approach for aspergilloma. The available literature related to the management of asymptomatic aspergilloma in pre-renal transplant setting is scarce and debatable. Opinion favoring surgery is that it is necessary to eliminate the fungus reservoir before transplantation because of the inadequacy of pharmacological fungus control measures in immunocompromised patients. We present a case of end-stage renal disease that was planned for renal transplantation and during the workup, was detected to have asymptomatic right upper lobe aspergilloma. He underwent surgical resection of the aspergilloma before undergoing successful renal transplantation. In this case report, we will discuss this case and controversies related to its management before undergoing successful renal transplantation.

Demographic and Clinical Profile of Dengue Fever in a Tertiary Care Hospital of South India.

BACKGROUND: Dengue fever is the most common viral communicable disease caused by the bite of Aedes aegypti mosquito. Worldwide about 3.9 billion people are at the risk of this infection. MATERIALS AND METHODS: This prospective study was done in patients of dengue fever admitted in a service hospital in the coastal area of southern India from 01 Jan 2018 to 31 Dec 2018. RESULTS: 751 patients of confirmed dengue patients were admitted with 555 (73.9%) males and 196 (26.1%) females. The mean age was 30.6 (SD± 10.48) years, mean day of admission after the onset of illness was 3.4 days (SD±2.76). The most common presentation was fever (99.33%) followed by myalgia (77.62%), headache (67.24%), vomiting (35.41%), nausea (26.76%) and fatigue (9.05%). Bleeding diathesis was evident in 97patients (12.91%). 306 (40.75%) patients presented with warning signs. The mean duration of hospitalization was 5.73 (SD± 2.75) days. Four patients died due to severe dengue (mortality rate-0.53%). CONCLUSION: Intense monitoring, early detection, and management of complications can prevent mortality in dengue.

Clinical Profile, Histopathological Features and Outcome of IgA Nephropathy in a Tertiary Care Hospital in India.

IgA nephropathy (IgAN) is reported to be more common in Asians and is considered to be a very progressive disease with worse outcome. The present study encompasses a cohort of biopsy-proven IgAN in a tertiary care hospital to characterize the initial clinical presentation, Oxford classification profile and one year follow up of patients with clinical and biochemical investigations. All renal biopsies with a diagnosis of primary IgAN were included. In all biopsies with ≥8 viable glomeruli, the MEST-C scores were analyzed, according to the Oxford criteria. Demographic and clinical data included age, gender, presence of hypertension, presence of hematuria and edema. Baseline investigations include urine protein semiquantitative, spot urine protein creatinine ratio, 24-h urinary protein, serum creatinine, and serum albumin. All the details of the use of antiproteinuric drugs and immunosuppressive drugs were recorded. Total 48 renal biopsies (21.62%) were diagnosed as primary IgAN. Thirty-seven (77.08%) had renal dysfunction on initial presentation out of which 31 (64.5%) patients had subnephrotic range proteinuria (SNRP). MEST-C lesions distribution were interpreted in 39 patients. 42.85% of patients with nephrotic range proteinuria (NRP) and 55.55% of patients with SNRP had renal deterioration during follow up period while 28.57% patients with NRP and 41.66% patients with SNRP had reached end-stage renal disease (ESRD). Our study population of IgAN has a unique clinical profile with hypertension, microscopic hematuria and subnephrotic proteinuria as the predominant clinical presentation. In spite of low MEST-C score in our study cohort, the disease has an aggressive course with 47.91% of patients with renal function deterioration and about one third follow up patients approaching ESRD during the study period.

Disseminated Histoplasmosis Masquerading as Significant Weight Loss Eight Years Post Renal Transplant.

With the advent of potent immunosuppressive therapies, renal transplant recipients are more susceptible to a variety of infections with atypical pathogens and presentations. In the setting of many years post-renal transplant, weight loss may be due to occult systemic fungal infection and if left untreated it may evolve with multisystem involvement. We describe a case with significant weight loss who got admitted for the evaluation for post-transplant lympho- proliferative disorder. The 30-year-old male patient presented with weight loss eight years post- renal transplant and detailed evaluation revealed systemic fungal infection involving cutaneous, pulmonary, and hematopoietic systems.
