Nephrology in a Resource Limited Setting, Gaza Edition


by Nimra Sarfaraz

What did I expect from the healthcare system going into the Gaza strip, seemingly one of the most inaccessible and dangerous places on earth ?

It’s embarrassing to say that media portrayals played a role in my notions. I was expecting to see a lack of physicians in a weak system with destruction all around. What I saw was simultaneously heartbreaking and comforting. I went with a team from MedGlobal, a non profit aimed at providing sustainable health care services to refugees, the most vulnerable in crisis areas and in low resource settings. Through MedGlobal, a diverse team from a professional, ethnic and religious backgrounds formed. Our team consisted of specialists in pulmonary critical care, Ob/Gyn, pediatrics, colorectal surgery, surgical oncology, anesthesia, pediatrics, nephrology, heme/onc and neurology. The team had clinicians from both the UK and the US with members identifying as Hindu, Jewish, Muslim, Catholic, Christian and agnostic; our unity around a common goal was beautiful to be immersed in. Our goal was to provide patient care, teaching and donating direly needed medical supplies, all of us were there on our own time and paid our own expenses.

On our first day there, we met with officials from the Ministry of Health and heard from leaders in the oldest and biggest hospital, Al-Shifa . What I will always remember more so than the jarring statistics was the sense of pleading to be heard, heard by the global community about what is happening. There’s a mingled guilt and helplessness in situations like this and I always come away wondering what sheer dumb luck has led me to such a position of comfort and privilege to sit across from individuals ever capable and exemplifying resilience. Later in the day the clinicians dispersed to meet with their Palestinian counterparts in one of two of the main hospitals we were working at, Al-Shifa Hospital or Nasser Hospital with the purpose of understanding each specialty’s work flow and assessing needs for future missions. I was paired and rounded with Dr. Riad, a bright nephrologist who had studied and trained in Egypt. We rounded on patients together and saw cases that ranged from run of the mill AKI to more complex cases such as steroid resistant childhood nephrotic syndrome that was now worsening, prompting a change in therapy. We visited the dialysis unit where many patients greeted Dr. Riad more as a friend. At the end of the day, when the group reconvened over dinner, all our experiences were similar – the lack wasn’t of human capital or education, the handicap was in a stifling lack of resources and mobility. Half of basic necessary drugs are at zero stock level, meaning there are not enough essential medications to effectively run a hospital to last through the next month. Astounding. The average amount of electricity per day is 7 hours. Dr. Aarti Garg, who did laparoscopic colon surgery on this trip, witnessed firsthand electricity flickering mid operation: luckily, big hospitals have generators but what of regular people?

What was I able to contribute as a nephrologist ?

Honestly the nephrologists there are capable and bright. They are deft at managing complex cases and have access to medications such as tacrolimus, mycophenolate and steroids. Uptodate is a highly cherished resource. Some of the more expensive medications, such as rituximab, are impossible to access because of the blockade. If a patient needs these medications, they need to be transferred out of the Strip. Transfer to more advanced centers is an onerous process, as on average 43 people are given permission to leave per day. Thinking comparatively to Las Vegas, a city of about the same size, to imagine only 43 people allowed to leave Las Vegas per day is mind boggling. People can’t leave to study, to visit family or to get more advanced and necessary medical care. Kidney biopsies that are done are sent across the border to neighboring countries to be analyzed. There is no doubt room for improvement, though it would be remiss to comment without also noting that these limitations will be difficult to overcome unless the prevailing root circumstances change. One notable example was the number of patients in the dialysis unit and the space each patient was allotted. The dialysis unit was full to the brim with one patient able to reach over and touch their neighbor, privacy and space, you see, is a luxury in a densely populated area with limited resources. Medications such as erythropoietin and calcitriol were not available; many patients asked us if we were able to provide these medications on a regular basis. 

I have gravitated towards point-of-care ultrasound particularly because of ease of use, rapid diagnostic ability and practicality of use, especially in low resource settings. I’ve previously taken a course with MedGlobal and have been using the Butterfly ultrasound probe on a regular basis. The Intensivists at my home institution have guided and taught me along the way as well. I was tasked with teaching a Point-of-Care Ultrasound workshop to the Internal Medicine and Intensive Care physicians at Nasser and Al-Shifa Hospitals; around 35 med students and attendings attended between two hospital systems. The workshop was well received and we did bedside ultrasound on patients in the Intensive Care Unit there. This part of my time there was likely the most beneficial of contributions to the most amount of people as the clinicians there are going to be using what they’ve learned on an ongoing basis. 

I encourage anyone with even a fleeting curiosity to delve for themselves into the complexities of the situation and with intentional conscience not forget the humanity of people, approach learning about this situation with empathy. Often times the most common narrative is not reflective of reality.

#NephMadness Choosing Wisely Campaign (#NCWC) – Pediatric Nephrology Region (#PedsRegion)

Blog Post


As we head into #NephMadness 2018, many of us are wondering how the Blue Ribbon Panel will make its decisions on which teams they select to advance to the next round. Here we take a look at the Pediatric Nephrology Region (#PedsRegion on Twitter) to see if there is any lean towards one team being victorious over another in each match-up.

Genes in CAKUT vs. Environment in CAKUT:

Congenital anomalies of the kidneys and urinary tract (CAKUT) are the most common cause of CKD in children. Kidney organogenesis is a precise, multi-step process that begins around 3 weeks gestation with formation of the pronephros and continues through the 36th week of gestation as the final kidneys undergo nephrogenesis. Because of the complexity of kidney development, multiple genetic and environmental insults can influence organogenesis and lead to abnormal formation of kidney and/or urinary tract structures. This #NephMadness rivalry is a battle of “nature vs. nurture” to see which team reigns supreme.

It’s tough to get a read from selection committee member Michelle Rheault’s (@rheault_m) scouting report on this match-up. She touches upon the 50+ genes that have been discovered thus far that are implicated in various congenital anomalies, ranging from renal agenesis to primary vesicoureteral reflux, and how next-generation sequencing could identify a potential cause for CAKUT in 5-10% of cases. Given her research interest in Alport syndrome, a disorder with a clear genetic basis, and her recent comments on Twitter, it may suggest she is trying to sway the Blue Ribbon Panel towards choosing the “Genes in CAKUT” team:

Then again, in the scouting report she emphasizes the burden of maternal diabetes and obesity in pregnancy and the risks of prematurity, which affect millions of babies born each year. This suggests a possible lean towards environment due to its greater impact on kidney health at a population level.

On a global scale, over 15 million preterm births occur each year. Prematurity leads to the arrest of nephron development and renal hypoplasia although some nephron development may continue after birth. Unfortunately, while premature infants are trying to form a few last nephrons after birth, they are exposed to nephrotoxic medications in the course of their care that may further disrupt this process.

Has the Blue Ribbon Panel leaked any secrets about their thoughts on genes vs. environment in CAKUT? It’s hard to tell as no one on the panel has talked about this match-up on Twitter yet.

A quick PubMed search may offer other clues into how the panelists may vote. Deidra Crews (@DrDeidraCrews), for example, is interested in socioeconomic factors that lead to racial disparities in chronic kidney disease for African Americans. Recognizing the role that environment plays in the risk of kidney disease in this population, it is possible she may vote for “Environment in CAKUT.” Looking at Tazeen Jafar’s research interests in ethnic disparities in the treatment of kidney disease in South Asian countries, this may signal another vote for “environment” as well.

On the genetics side, Michael Choi (@Mike_J_Choi) has a research interest in APOL1 risk alleles. Fiona Loud (@FionaCLoud), the Policy Director at Kidney Care UK, is a renal transplant recipient herself and has tuberous sclerosis, a genetic disorder of tumor growth associated with renal manifestations including angiomyolipomas, cysts, and renal cell carcinoma. This may signal two votes from these panelists for “Genes in CAKUT.”

So where does this leave us? Two Blue Ribbon Panel members with possible votes for “Environment in CAKUT” and two potential votes for “Genes in CAKUT,” but it’s anybody’s game.

GN Diagnosis vs. HTN Diagnosis:

Glomerular diseases comprise the second most common cause of pediatric chronic kidney disease, just behind CAKUT. However, they are arguably the most challenging cases we see in our practice and come with plenty of co-morbidities and complications. Many of us have had that experience of a patient with steroid-resistant nephrotic syndrome that has gone through our limited arsenal of immunosuppression down the path to ESKD, or that challenging lupus nephritis patient with multiple lupus flares while on oral steroids and MMF. Hypertension, on the other hand, is also a tough team to beat. There is a known association of high BP in childhood with adult hypertension, yet many children go undiagnosed. Furthermore, obtaining accurate BP readings in children can be a challenge (older studies have shown that infants who cry raise their BP by 30-50 mmHg on average!) and BP targets are different based on the child’s age, gender, and stature.

Going back again to the selection committee member for the #PedsRegion, Michelle Rheault’s research interest in Alport syndrome may suggest she could be setting up the Blue Ribbon Panel to vote for “GN Diagnosis.” However, again looking at kidney disease from a population-level standpoint, she makes the following argument about the burden of pediatric HTN and the consequences of us not identifying it early:

Unfortunately, children with high blood pressure grow up to be adults with high blood pressure. In the Childhood Determinants of Adult Health study, children with blood pressure >90th percentile had a 35% increased risk of elevated blood pressure or hypertension in adulthood. Children with hypertension also demonstrate increased intermediate markers of cardiovascular disease including increased LV mass, carotid intimal media thickness, and pulse wave velocity. By putting in a little effort early to diagnose and treat childhood hypertension, a lifetime of cardiovascular disease risk can be minimized. From a potential health system impact standpoint, this team has a clear leg up on the competition.

This, in addition to the hype surrounding the newly released AAP Pediatric Hypertension guidelines, make it seem like “HTN Diagnosis” has a home court advantage.

But what does the Blue Ribbon Panel have to say? A quick Twitter search has not revealed any clear bias from panelists towards one particular team. When looking at PubMed, Michael Choi’s research interests in APOL1 and glomerular disease as a whole suggests a vote for “GN Diagnosis.” Tazeen Jafar’s research on BP control in rural South Asian communities and involvement in the Control of Blood Pressure and Risk Attentuation (COBRA) trial suggests a lean towards “HTN Diagnosis” with her vote.

Like the CAKUT bracket, “GN Diagnosis” vs. “HTN Diagnosis” remains a toss-up. Glomerular diseases, though relatively uncommon in the whole pediatric population, is a more common cause of CKD and ESKD in children than in adults and fraught with management challenges. However, given the long-term risks of not identifying elevated BP in childhood and the rising prevalence of HTN in this age group, particularly due to the obesity epidemic, I would lean towards “HTN Diagnosis” as claiming victory but not by a big margin.
